DISCLOSURE OF THE INVENTION

Problems to be Solved by the Invention

In a paper sheet processing device, because of abrasion or wearout of processing means, it is occasionally necessary to replace the processing means. In such cases, in the device of Patent literature 1, it was necessary to disassemble some parts of the device and to replace them. Hence, there was a problem of requiring time and effort for replacement work and being unable to use the device during the replacement work.

In addition, in the paper sheet processing device disclosed in Patent literature 1, if various kinds of processing means are installed to provide various kinds of processing functions, the device is upsized. On the other hand, in actual circumstances, some of the various kinds of processing means are used less frequently.

Furthermore, in the device of Patent literature 2, a unit having a cutting round blade and secured at a predetermined position cuts paper sheets at a predetermined position; however, another unit is necessary to perform cutting at a different position; hence, numerous units are required to be prepared according to cutting dimensions.

On the other hand, the cutting waste elimination means in the conventional paper sheet processing device is secured at a predetermined position in the direction (the width direction of paper sheets) perpendicular to the carrying direction. Hence, if the cutting position is changed, the generation position of cutting waste is also changed, whereby problems described below are caused.

(1) Paper sheets are ejected to a paper ejection part without eliminating cutting waste; hence, it is necessary to eliminate the cutting waste at the paper ejection part.

(2) For the purpose of eliminating cutting waste, the position of the cutting waste elimination means is required to be changed manually each time the generation position of cutting waste is changed.

Still further, in the paper sheet processing device of Patent literature 1, the processing for cutting paper sheets in the carrying direction is performed while one fringe of the paper sheet is used as a reference, for example. Hence, in the paper sheet processing devices of Patent literatures 1 and 6, paper feeding is performed such that the fringe of the paper sheet is aligned along a guide.

However, in this kind of paper sheet processing device, no problem occurs in the case that the printed area (the area wherein printing was performed) of the paper sheet is at a normal position, but in the case of an abnormal position, a problem occurs. In other words, in FIG. 37, as shown in (a), in the case that the printed area 101 of a paper sheet 100 is inclined with respect to the fringe 111 of the paper sheet 100, the cutting in the carrying direction with reference to the fringe 111 is performed so as to be inclined with respect to the printed area 101 as indicated by the alternate long and short dash lines of (b); furthermore, the cutting in the direction perpendicular to the carrying direction with reference to the fringe 112 is also performed so as to be inclined with respect to the printed area 101 as indicated by the alternate long and short dash lines of (c); as a result, as shown in (d), a paper sheet 100 having the printed area 101 kept inclined with respect to the fringes 111 and 112 is obtained.

The technology of Patent literature 7 is intended to solve the problem shown in FIG. 37; however, a plate for controlling the fringes of paper sheets is provided in a paper feeding device part, and it is conceivable that this plate interferes with the feeding of paper sheets being inclined, whereby it is conceivable that carrying capable of solving the problem described above cannot be performed stably.

A first object of the present invention is to provide a paper sheet processing device capable of reducing time and effort required for replacement work for processing means.

A second object of the present invention is to provide a paper sheet processing device which is capable of moving the position of the processing means and is capable of being applicable to multiple cutting dimensions by using one unit. Furthermore, the object is to provide a paper sheet processing device capable of performing proper processing even in the case that the printed position of a paper sheet is misaligned.

A third object of the present invention is to provide a paper sheet processing device being not upsized while having various kinds of processing functions.

A fourth object of the present invention is to provide a paper sheet processing device capable of securely eliminating cutting waste from the carrying route without manually changing the position of the cutting waste elimination means even if the generation position of cutting waste is changed.

A fifth object of the present invention is to provide a paper sheet processing device capable of processing a paper sheet having a printed area inclined with respect to the fringe thereof and obtaining a paper sheet having the printed area being in parallel with the fringe.

BEST MODES FOR CARRYING OUT THE INVENTION

First Embodiment

FIG. 1 is a schematic vertical sectional view showing the whole of a paper sheet processing device in accordance with a first embodiment of the present invention. A paper sheet processing device 1 is provided with a paper feeding part 11 comprised of a paper feeding tray and a paper ejection part 12 comprised of a paper ejection tray on both ends of the device body 10 thereof. A carrying route 20 is formed of carrier means 2 comprising multiple pairs of rollers 21 in the range from the paper feeding part 11 to the paper ejection part 12. Carrier driving means (not shown) are connected to the carrier means 2. In addition, a carrying correction means 803, an information reading means 804, a rejection means 806, a first cutting device part 4A, a second cutting device part 4B, a third cutting device part 4C, a cutting waste dropping means 807, a fourth cutting device part 4D and a fold forming device part 5 are installed on the carrying route 20 from the side of the paper feeding part 11. These are all supported on the device body 10. Furthermore, processing driving means (not shown) are connected to these means. The first cutting device part 4A, the second cutting device part 4B, the third cutting device part 4C, the fourth cutting device part 4D and the fold forming device part 5 correspond to the first type processing device part.

Besides, the paper sheet processing device 1 is provided with a control means 800 for controlling the operation of the whole device inside the device body 10. The control means 800 has a CPU connected to an operation panel (not shown). The control means 800 also performs control, for example, as a position control means and a processing control means, these being described later. Moreover, the paper sheet processing device 1 has a trash box 801 for accommodating cutting waste generated by cutting paper sheets at the bottom part inside the device body 10.

In FIG. 2, (a) shows an example of a paper sheet that is processed by the paper sheet processing device 1 in accordance with the present invention. On this paper sheet 100, a position mark 102 and a bar code 103 as well as a main printed part 101 are printed. The bar code 103 indicates processing information serving as the content of a series of processing to be performed for the paper sheet 100.

The paper sheet processing device 1 operates as described below.

First, paper sheets 100 are fed one by one from a bundle of the paper sheets 100 placed on the paper feeding part 11 to the carrying route 20, and enter the carrying correction means 803. If a paper sheet 100 having being fed is inclined, the carrying correction means 803 straighten it. Furthermore, if two or more paper sheets 100 having being fed overlap, the carrying correction means 803 detects the state and stops the carrying of the paper sheets 100. In the case that one paper sheet 100 has been fed straight, the paper sheet 100 is carried to the next stage.

The paper sheet 100 having been carried to the next stage enters the information reading means 804 after its leading end is detected by a paper sheet end sensor 201. The information reading means 804 reads the position mark 102 and the bar code 103 of the paper sheet 100 by a CCD sensor 805. This information having been read is sent to the control means 800. The control means 800 stores the information having been read and controls the subsequent various means on the basis of it. The processing information indicated by the bar code 103 has the following content, for example. In other words, the content is to obtain eight paper sheets 200 each having a fold 210 as shown in (c) in FIG. 2 by applying cutting processing along the solid lines A, B, C and D and fold forming processing along the alternate long and short dash lines E to the paper sheet 100 as shown in (b) in FIG. 2. In the case of such processing information, the subsequent various means operate as described below. The paper sheet 100, the information of which was unable to be read at the information reading means 804, is judged that printing is unclear and is dropped into a rejection tray 802 disposed downward by the rejection means 806 provided next.

The paper sheet 100 having passed through the rejection means 806 enters the first cutting device part 4A after its leading end is detected by a paper sheet end sensor 202. The first cutting device part 4A is ON-controlled by the processing control means of the control means 800, and is controlled by the position control means of the control means 800 so that two cutting cutters are positioned at the positions indicated by the two solid lines A ((b) in FIG. 2), respectively. Hence, the paper sheet 100 is cut along the solid lines A, that is, in the carrying direction, by the first cutting device part 4A. As a result, the paper sheet 100 has the shape shown in (a) in FIG. 3 and is carried to the second cutting device part 4B provided next. Unnecessary pieces X1 are dropped into the trash box 801.

The second cutting device part 4B is ON-controlled by the processing control means of the control means 800, and is controlled by the position control means of the control means 800 so that two cutting cutters are positioned at the positions indicated by the two solid lines B ((b) in FIG. 2), respectively. Hence, the paper sheet 100 shown in (a) in FIG. 3 is cut along the solid lines B, that is, in the carrying direction, by the second cutting device part 4B. As a result, the paper sheet 100 has the shape shown in (b) in FIG. 3 and is carried to the third cutting device part 4C provided next.

The third cutting device part 4C is ON-controlled by the processing control means of the control means 800, and is controlled by the position control means of the control means 800 so that two cutting cutters are positioned at the positions indicated by the two solid lines C ((b) in FIG. 2), respectively. Hence, the paper sheet 100 shown in (b) in FIG. 3 is cut along the solid lines C, that is, in the carrying direction, by the third cutting device part 4C. As a result, the paper sheet 100 has the shape shown in (c) in FIG. 3 and is carried to the fourth cutting device part 4D. An unnecessary piece X2 is dropped into the trash box 801 by the cutting waste dropping means 807 provided at the next stage.

Before the paper sheet 100 shown in (c) in FIG. 3 enters the fourth cutting device part 4D, its leading end is detected by a paper sheet end sensor 202.

The fourth cutting device part 4D is ON-controlled by the processing control means of the control means 800. In the fourth cutting device part 4D, each time the cutting position is detected by a cutting position sensor 204, the paper sheet 100 shown in (c) in FIG. 3 stops at the cutting position indicated by each of the three solid lines D ((b) in FIG. 2). Furthermore, each time the paper sheet 100 stops, it is cut along each of the solid lines D, that is, in the direction perpendicular to the carrying direction, by a pair of cutting cutters 41. Hence, the paper sheet 100 has the shape shown in (d) in FIG. 3 and is carried to the fold forming device part 5. Unnecessary pieces X3 are dropped into the trash box 801.

The fold forming device part 5 is ON-controlled by the processing control means of the control means 800. In the fold forming device part 5, each time a folding position is detected by a folding position sensor 205, the paper sheet 100 shown in (d) in FIG. 3 stops at the folding position indicated by each of the two alternate long and short dash lines E. Furthermore, each time the paper sheet 100 stops, a fold 201 is formed along each of the alternate long and short dash lines E, that is, in the direction perpendicular to the carrying direction, by a pair of fold forming pressure molds 51. Hence, the paper sheet 100 has the shape shown in (e) in FIG. 3 and is fed to the paper ejection part 12.

The paper sheet processing device 1 operates as described above.

In the present invention, the first to third cutting device parts 4A to 4C are installed detachably from the device body 10.

The first cutting device part 4A is taken as an example and described below specifically.

The first cutting device part 4A comprises a cutting unit 70X and a unit accommodating part 9. The cutting unit 70X is configured as a unit for performing cutting. The unit accommodating part 9 is formed in the device body 10 and can detachably accommodate the cutting unit 70X.

FIG. 4 is a front view showing the cutting unit 70X, and FIG. 5 is a fragmentary perspective view of FIG. 4. The Y-direction in FIG. 5 indicates the carrying direction. The unit 70X is provided with a case part 700 and two cutting cutters (processing means) 72 and 74. The case part 700 comprises a top plate 701, two side plates 702 and 703, and a bottom frame 704. The two cutting cutters 72 and 74 are supported inside the case part 700. Two handles 7011 are attached on the top plate 701. The two side plates 702 and 703 are installed downward in the vertical direction from both sides of the top plate 701. Two screw shafts (moving means) 705 and 719, two upper guide shafts 706 and 707, two lower guide shafts 708 and 709, and two rotation shafts 710 and 711 are installed to span between the side plates 702 and 703. These shafts are all parallel. The two rotation shafts 710 and 711 are disposed at the upper and lower positions, respectively.

The cutting cutter 72 performs cutting by rubbing two rotary blades together up and down, and comprises an upper member 714 having an upper rotary blade and a lower member 715 having a lower rotary blade. In addition, the upper member 714 can move along the two upper guide shafts 706 and 707 as the screw shaft 705 passing through a screw engagement part 7050 rotates. Furthermore, the rotary blade of the upper member 714 is rotated by the rotation of the upper rotation shaft 710. The lower member 715 can move along the two lower guide shafts 708 and 709 together with the upper member 714. Furthermore, the rotary blade of the lower member 715 is rotated by the rotation of the lower rotation shaft 711.

The cutting cutter 74 has the same configuration as that of the cutting cutter 72 and is installed so as to be symmetrical with the cutting cutter 72. The cutting cutter 74 can move along the two upper guide shafts 706 and 707 as the screw shaft 719 rotates. The screw shaft 719 passes through a screw engagement part 7190. In addition, the rotary blade of the upper member 714 is rotated by the rotation of the upper rotation shaft 710. The lower member 715 can move along the two lower guide shafts 708 and 709 together with the upper member 714. Furthermore, the rotary blade of the lower member 715 is rotated by the rotation of the lower rotation shaft 711.

Moreover, the unit 70X is provided with pins 718 for supporting from below the paper sheets 100 passing through. The pins 718 are installed at three positions corresponding to the center and both sides of the paper sheet 100 in the width direction thereof. The pins 718 extend in the carrying direction and can pivot on a horizontal plane while the base ends 7181 thereof are used as fulcrums; when no external force is applied, they are configured to maintain the state of being directed in the carrying direction. Hence, when the pins 718 make contact with the cutting cutters 72 and 74, they are configured to keep away from the cutting cutters 72 and 74.

In addition, a gear 7051 is installed at the end of the screw shaft 705 protruding from the side plate 702 to the outside. Furthermore, a gear 7191 is installed at the end of the screw shaft 719 protruding from the side plate 703 to the outside. Moreover, gears 7101 and 7111 are installed at the ends of the two rotation shafts 710 and 711 protruding from the side plate 702 to the outside, respectively. The two gears 7101 and 7111 are coupled together, whereby the two rotation shafts 710 and 711 rotate reversely at the same time.

On the other hand, the unit accommodating part 9 is configured such that a first driving part 94, a second driving part 95 and a third driving part 96 are installed in a frame member 90 as shown in FIG. 6. The frame member 90 comprises two side plates 91 and 92 and a lower frame 93.

The first driving part 94 is installed on the upper part of the side plate 91 and comprises a gear 941 and a motor 942 for rotating the gear 941. The gear 941 is positioned inside the side plate 91. The motor 942 is positioned outside the side plate 91.

The second driving part 95 is installed on the upper part of the side plate 92 and comprises a gear 951 and a motor 952 for rotating the gear 951. The gear 951 is positioned inside the side plate 92. The motor 952 is positioned outside the side plate 92. The first driving part 94 and the second driving part 95 are installed symmetrically.

The third driving part 96 is installed at the lower part of the side plate 91 and comprises a gear 961, a motor 962, gears 963, 964, 965 and 966, and pulleys 967 and 968. The gear 961 is positioned inside the side plate 91 and above the lower frame 93. The motor 962 is positioned inside the side plate 91 and below the lower frame 93. The gears 963, 964, 965 and 966 and the pulleys 967 and 968 are positioned outside the side plate 91 to transmit the driving force of the motor 962 to the gear 961.

The gear 961 of the third driving part 96 protrudes inside the side plate 91 further than the gear 941 of the first driving part 94.

In addition, in the first cutting device part 4A, when the unit 70X is accommodated in the unit accommodating part 9 in the first cutting device part 4A, the gear 7051 is coupled with the gear 941, the gear 7111 is coupled with the gear 961, and the gear 7191 is coupled with the gear 951 as shown in FIG. 6. The unit 70X accommodated in the unit accommodating part 9 is positioned and then secured to the side plates 91 and 92 by screws 991 and 992.

When the unit 70X is accommodated in the unit accommodating part 9, the first cutting device part 4A operates as described below. That is to say, the unit 70X is ON-controlled by the processing control means of the control means 800, and is controlled by the position control means of the control means 800 so that the two cutting cutters 72 and 74 are positioned at the cutting positions. In other words, by the position control means, the motor 942 of the first driving part 94 is operated for a predetermined time period, and the cutting cutter 72 is moved to its cutting position, and, additionally, the motor 952 of the second driving part 95 is operated for a predetermined time period, and the cutting cutter 74 is moved to its cutting position. Furthermore, by the processing control means, the motor 962 of the third driving part 96 is operated, the rotary blades of the cutting cutters 72 and 74 are rotated, and the paper sheet 100 is cut at the positions of the cutting cutters 72 and 74 in the carrying direction.

The second cutting device parts 4B and 4C have the same configuration as that of the first cutting device part 4A, and operate similarly. In addition, the first, second and third cutting device parts 4A, 4B and 4C each control the cutting cutters 72 and 74 to the positions shown in FIG. 7 serving as a schematic plan view, thereby performing the cutting described above.

As described above, in the paper sheet processing device 1 having the configuration described above, the cutting units for performing cutting in the first, second and third cutting device parts 4A, 4B and 4C, respectively, are installed detachably from the device body 10; hence, the following effects can be achieved. That is to say, even in the case that the cutting cutter of one of the cutting device parts, for example, the first cutting device part 4A, is required to be replaced because of abrasion or the like, replacement can be performed simply by taking the cutting unit 70X from the unit accommodating part 9 of the device body 10 and by accommodating a new cutting unit 70X being prepared as a spare in the unit accommodating part 9. Hence, time and effort required for replacement work can be reduced.

In addition, in the paper sheet processing device 1 having the configuration described above, even in the case that the first cutting device part 4A, for example, is configured as the cutting unit 70X, the movement control of the positions of the cutting cutters 72 and 74 can be performed in the unit 70X; hence, application to various kinds of cutting positions is possible, and proper cutting can be performed even in the case that the printed position of the paper sheet 100 is misaligned.

Furthermore, in the paper sheet processing device 1 having the fold forming device part for forming folds in the carrying direction and a perforation forming device part for forming perforations in the carrying direction, the fold forming device part and the perforation forming device part may be installed detachably from the device body 10.

In the case that the fold forming device part for forming folds in the carrying direction is installed detachably from the device body 10, the fold forming device part comprises a fold forming unit and the unit accommodating part 9. The fold forming unit is configured such that the cutting cutter of the cutting unit 70X is replaced with a fold forming tool. As shown in FIG. 8 and FIG. 9 serving as a view taken in the direction of arrow IX of FIG. 8, the fold forming tool operates to fit the convex part 7811 of a rotary blade 781 into the concave part 7821 of a receiving blade 782 together with a paper sheet to press the paper sheet, thereby forming a fold on the paper sheet. The rotary blade 781 is held in the upper member 714 and is rotated by the rotation of the rotation shaft 710. The receiving blade 782 is held in the lower member 715 and is rotated by the rotation of the rotation shaft 711. The height of the receiving blade 782 can be changed by applying an eccentric shaft; hence, the depth of the fold can be adjusted by changing the fitting depth of the convex part 7811 with respect to the concave part 7821.

In the case that the perforation forming device part for forming perforations in the carrying direction is installed detachably from the device body 10, the perforation forming device part comprises a perforation forming unit and the unit accommodating part 9. The perforation forming unit is configured such that the cutting cutter of the cutting unit 70X is replaced with a perforation forming tool. As shown in FIG. 10 and FIG. 11 serving as a view taken in the direction of arrow XI of FIG. 10, the perforation forming tool operates to slidingly-contact the sharp edge part 7121 of a gear blade 712 with the wall of the concave part 7131 of a receiving blade 713 together with a paper sheet to form perforations in the paper sheet. The gear blade 712 is held in the upper member 714 and is rotated by the rotation of the rotation shaft 710. The receiving blade 713 is held in the lower member 715 and is rotated by the rotation of the rotation shaft 711. The height of the receiving blade 713 can be changed by applying an eccentric shaft; hence, the width of the perforation can be adjusted by changing the fitting depth of the sharp edge part 7121 with respect to the concave part 7131.

In the embodiment described above, the position mark 102 and the bar code 103 printed on the paper sheet 100 are read, and the device itself automatically performs the movement control of the positions of the processing means, such as the cutting cutters, on the basis of the information having been read; however, the paper sheet processing device in accordance with the present invention is not limited to have this kind of configuration; for example, an embodiment described below can be adopted. That is to say, the content of processing (the dimensions of paper sheets, the type of processing, etc.) and processing positions are input from an operation panel (not shown) and preset as processing forms. At the time of processing, a processing form being set is selected. Hence, the movement control of the positions of the processing means is performed, and paper sheet processing corresponding to the selected processing form is done.

Second Embodiment

FIG. 12 is a schematic vertical sectional view showing the whole of a paper sheet processing device in accordance with a second embodiment of the present invention. In FIG. 12, the same components as those shown in FIG. 1 are designated by the same numerals. A paper sheet processing device 1 is provided with a paper feeding part 11 comprised of a paper feeding tray and a paper ejection part 12 comprised of a paper ejection tray on both ends of the device body 10 thereof. A carrying route 20 is formed of carrier means 2 comprising multiple pairs of rollers 21 in the range from the paper feeding part 11 to the paper ejection part 12. In addition, carrier driving means (not shown) are connected to the carrier means 2. Furthermore, a carrying correction means 803, an information reading means 804, a rejection means 806, a first cutting device part 4A, a second cutting device part 4B, a third cutting device part 4C, a cutting waste dropping means 807, a fourth cutting device part 4D, a fold forming device part 5 and an optional processing device part (second type processing device part) 7 are installed on the carrying route 20 from the side of the paper feeding part 11. These are all supported on the device body 10. Furthermore, processing driving means (not shown) are connected to these means.

Besides, the paper sheet processing device 1 is provided with a control means 800 for controlling the operation of the whole device inside the device body 10. The control means 800 has a CPU connected to an operation panel (not shown). The control means 800 also performs control, for example, as a position control means and a processing control means, these being described later. Moreover, the paper sheet processing device 1 has a trash box 801 for accommodating cutting waste generated by cutting paper sheets at the bottom part inside the device body 10.

In the paper sheet processing device 1 in accordance with this embodiment, the configuration and operation of the parts from the paper feeding part 11 to the fold forming device part 5 are the same as those in accordance with the first embodiment. In other words, the paper sheet 100 shown in (a) in FIG. 2 is fed to the optional processing device part 7 while having the shape shown in (e) in FIG. 3.

Next, the configuration of the optional processing device part 7 will be described.

In the optional processing device part 7, a processing content can be selected as desired from among multiple kinds of contents. More specifically, the optional processing device part 7 comprises multiple processing units 70 and a unit accommodating part 9A as shown in FIG. 13. The multiple processing units 70 are multiple processing means for performing processing of different kinds of contents, each being configured as a unit. The unit accommodating part 9A is installed in the device body 10 and can detachably accommodate a processing unit that is selected as desired from among the processing units 70.

The unit accommodating part 9A is configured such that a first driving part 94, a second driving part 95, a third driving part 96, a fourth driving part 97 and a detection part (processing type detecting means) 98 are installed on a frame member 90. The frame member 90 comprises two side plates 91 and 92 and a lower frame 93.

The first driving part 94 is installed on the upper part of the side plate 91 and comprises a gear 941 and a motor 942 for rotating the gear 941. The gear 941 is positioned inside the side plate 91. The motor 942 is positioned outside the side plate 91. The second driving part 95 is installed on the upper part of the side plate 92 and comprises a gear 951 and a motor 952 for rotating the gear 951. The gear 951 is positioned inside the side plate 92. The motor 952 is positioned outside the side plate 92. The first driving part 94 and the second driving part 95 drive screw shafts for moving the positions of processing means (for example, cutting cutters, perforation forming tool, fold forming tool, etc.). In the case that a processing means comprises two cutting cutters, for example, the first driving part 94 and the second driving part 95 are installed symmetrically on both the side plate 91 and the side plate 92 so as to correspond to the respective cutting cutters.

The third driving part 96 is installed at the lower part of the side plate 91 and comprises a gear 961, a motor 962, gears 963, 964, 965 and 966, and pulleys 967 and 968. The gear 961 is positioned inside the side plate 91 and above the lower frame 93. The motor 962 is positioned inside the side plate 91 and below the lower frame 93. The gears 963, 964, 965 and 966 and the pulleys 967 and 968 are positioned outside the side plate 91 to transmit the driving force of the motor 962 to the gear 961. The third driving part 96 drives a processing means (for example, a business card cutting tool having multiple rotary blades) requiring large power for processing. Hence, the motor 962 has a large driving force.

The fourth driving part 97 is installed at the lower part of the side plate 92 and comprises a gear 971, a motor 972, gears 973, 974, 975 and 976, pulleys 977 and 978, and gears 979 and 980. The ge
