[Processed product arrangement pattern of paper]
FIG. 4 is a plan view showing an example of an array pattern of the processed products Q of the paper P. FIG. The arrangement pattern of the processed products Q shown in the figure is such that four processed products Q having folds are produced from one sheet of paper P. Basically, four cutting lines S extending in parallel with the transport direction F, two folding lines C extending in the width direction W, and four cutting lines K extending in the width direction W are set. The two folding lines C and the cutting line K are formed by cutting the paper P in parallel with the conveyance direction F along the cutting line S, and removing the long paper pieces Ja and Jb cut from the paper P. Each of the two sheets of paper Pc arranged side by side is formed by being subjected to crease processing or cutting processing a plurality of times.

In the array pattern of the processed products shown in FIG. 4, since there are four cutting lines S parallel to the conveying direction F by the slitter mechanism 20, the center unit 20b or the most downstream unit 20c in the slitter mechanism 20 is provided. Only one of them is moved to a predetermined position in the width direction W for cutting, and the other is moved to the outside of the sheet conveying path 5 to be on standby.

Various kinds of work setting information to be applied to the paper P regarding the arrangement pattern of the processed products Q are set by the user using the operation panel 46 or recorded on the barcode M2 of the paper P. . The various setting information includes whether or not to drive the storage box moving unit 66, the movement amount of the paper piece storage box 65, the movement speed, the number of movements when reciprocating, the vibration width, the vibration cycle, the vibration speed, and the number of vibrations. When at least one piece of information, the paper pieces J in different states are mixed in the paper piece storage box 65, information on how to combine different movement operations of the paper piece storage boxes 65 based on the state of each paper piece J is included.

[Overview of overall processing equipment processing]
(1) From the operation panel 46 shown in FIG. 1, the user can determine the size of paper P, stiffness, thickness, type, arrangement, number and size of processed product Q, and size of paper piece J cut out from paper P. Various work setting information relating to the length and number in a predetermined direction such as the conveyance direction F and the width direction W is input. Instead of this manual input or in cooperation with the manual input, the work setting information can be automatically input by reading the barcode M2 or the like by the reading unit 26.

(2) A plurality of sheets P stacked on the sheet feeding tray 3a of the sheet feeding unit 3 in FIG. 1 are supplied one by one from the upper end to the conveying path 5 by the suction conveying belt mechanism 8a and the sheet feeding roller 8.

(3) The reading unit 26 reads the position mark M1 of the paper P and, if necessary, the barcode M2, and acquires various work setting information to be applied to the paper P.

(4) In the reject mechanism 25, if reading by the reading unit 26 is impossible and the processing conditions are unknown, the reject mechanism 25 operates on the paper P, drops the unreadable paper P and discards it. Collected in the tray 25a.

(5) In the slitter mechanism 20, the paper P is cut by a plurality of cutting lines S parallel to the transport direction F by the cutting blade 36. Unnecessary paper pieces Ja at both the left and right edges cut out from the paper P by the most upstream unit 20a are moved downward by the margin dropping member 55 to the lower paper piece collection unit 23, guided by the guide 69, and supplied to the paper piece storage box. 65.

(6) In the paper piece dropping mechanism 27, the unnecessary paper piece Jb cut from the paper P by the central unit 20b and the most downstream unit 20c in the slitter mechanism 20 is moved downward to the lower paper piece collection unit 23. In the paper piece storage box 65.

(7) In the crease mechanism 21, a crease is formed along the fold line C in the width direction W.

(8) In the cutter mechanism 22, the paper P is sequentially cut along the respective cutting lines K, and the paper pieces Jc that are cut out from the paper P and become unnecessary are guided by the guide 70 and collected by the paper piece collection unit 23. The processed product Q obtained by the cutting and crease processing is conveyed to the paper receiving unit 2 and stacked.

In this manner, during the processing process of the paper P, the paper piece J that has been cut off from the paper P by the slitter mechanism 20 and the cutter mechanism 22 and is no longer necessary is stored in the paper piece storage box 65. The control unit 45 controls the driving of the storage box moving unit 66 according to the detection result of the paper piece detection unit 68. Then, the control unit 45 drives the storage box moving unit 66 when the side paper piece detection unit 88 detects the paper piece J in the paper piece storage box 65 over a predetermined time, and the paper piece storage box 65 is driven. Vibrate.

At this time, the control unit 45 drives the motor 80 to rotate the drive gear 81 and rotates the crank gear 82 accordingly. When the crank gear 82 rotates, the pair of crank members 78 rotate, and the pedestal 76 is moved parallel to the transport direction F on the horizontal plane by the link mechanism of the crank arm 83. Then, the paper piece storage box 65 on the carriage 71 is moved along the conveyance direction F by the movement of the base 76. When the control unit 45 controls the drive time of the motor 80, the movement of the paper piece storage box 65 by the storage box moving unit 66 is a reciprocating movement. The upstream side wall 64 and the downstream side wall 64 are reciprocated between a direction away from the paper piece J and a direction adjacent thereto.

Thus, for example, as shown in FIG. 5A, when the paper piece J is in contact with the upper portion of the side wall 64 on the downstream side of the paper piece storage box 65, the side wall moving unit 56 first separates the side wall 64 from the paper piece J. The side wall 64 is moved in the direction of the arrow G which is the same as the conveying direction F to be moved. Then, as shown in FIG. 5B, the posture of the paper piece J collapses, and the posture of the paper piece J becomes inclined with an angle with respect to the vertical direction V being larger than that in FIG. Further, the side wall moving unit 56 moves the side wall 64 from the state shown in FIG. As a result, as shown in FIG. 5C, the posture of the paper piece J further collapses, and the posture has a larger angle with respect to the vertical direction V.

  Therefore, the paper piece J moved downward toward the paper piece storage box 65 leans against the side wall 64 of the paper piece storage box 65 and leans against the side wall 64 and maintains a posture substantially parallel to the vertical direction V while being in contact with the side wall 64. When the paper piece J is likely to be bulky, the side wall moving unit 56 moves in a direction in which the side wall 64 is separated from the paper piece J in contact with the upper part of the side wall 64 of the paper piece storage box 65. The angle is increased so that the bulk of the paper piece J can be eliminated.

In addition, the storage box moving unit 66 moves the paper piece storage box 65 a plurality of times along the conveyance direction F on the horizontal plane, so that the side wall moving unit 56 is separated from the direction away from the paper piece J and the adjacent direction. Therefore, the paper piece J is tilted so that the angle of the paper piece J with respect to the vertical direction V becomes larger and the bulk of the paper piece J can be further reduced.

And since the bottom member moving part 57 moves the bottom member 63 of the paper piece storage box 65 in a predetermined direction, the contact portion of the bottom end portion of the paper piece J with the bottom member 63 moves in the predetermined direction as the bottom member 63 moves. As a result, the paper piece J is out of balance and tilted. In particular, when the paper pieces Ja and Jb cut and cut by the cutting line S by the cutting blade 36 of the slitter mechanism 20 are stored in the paper piece storage box 65, as shown in FIG. In many cases, D comes into line contact with the bottom member 63 in a posture parallel to the upright posture. In this state, the bottom member moving part 57 moves the bottom member 63 along the transport direction F, so that the bottom member 63 at the lower edge D of the paper piece J is moved to the bottom member 63 as shown in FIGS. Is no longer a line contact. Then, the lower end edge D of the paper piece J and the bottom member 63 are in point contact or no longer contact with each other, and the paper piece J cannot be maintained in the standing posture and tilts. Thus, the bulkiness of the paper piece storage box 65 can be reduced efficiently.

Further, since the side wall 64 of the paper piece storage box 65 is moved along the conveyance direction F of the paper P by the side wall moving unit 56, the bulk of the long paper pieces Ja and Jb cut by the cutting blade 36 of the slitter mechanism 20. This can be solved efficiently.

Further, as shown in FIG. 6A, when there is a long paper piece J in a standing posture, for example, by being caught in a gap between the paper pieces Jd accumulated at the bottom of the paper piece containing box 65, the containing box moving unit 66 is operated by the cutting blade. The paper piece storage box 65 is moved in substantially the same direction as the cutting direction 36. Thus, as shown in FIGS. 2B and 2C, the long paper piece J in the standing posture can be tilted to reduce the bulkiness.

In addition, even when there is a paper piece J in a standing posture sandwiched between the gaps of the paper pieces Jd accumulated at the bottom of the paper piece containing box 65 as shown in FIG. By moving in the predetermined direction, the bottom member moving unit 57 moves the bottom member 63 of the paper piece storage box 65 in the predetermined direction. Accordingly, the paper piece Jd accumulated at the bottom of the paper piece storage box 65 is moved in a predetermined direction along with the movement of the bottom member 63, the gap between the paper pieces Jd is reduced, and the standing paper piece J is out of balance. Therefore, the standing paper piece J can be tilted.

When the paper piece J tilts due to the horizontal movement of the paper piece storage box 65 and the paper piece J is no longer detected by the side paper piece detection unit 88 because the bulkiness is reduced, the control unit 45 stops driving the storage box movement unit 66. Then, the movement of the paper piece storage box 65 is stopped. The control unit 45 may control to drive the storage box moving unit 66 for a predetermined time in advance, instead of the time until the paper piece J is no longer detected by the side paper piece detection unit 88.

Further, the control unit 45 detects the distance to the upper surface of the paper piece J accommodated in the paper piece accommodation box 65 based on the detection result of the upper paper piece detection unit 89. Then, the control unit 45 compares the detected height of the paper piece J in the paper piece storage box 65 with a preset height so as to notify the fullness of the paper piece storage box 65. When the height of the paper piece J in the paper piece storage box 65 exceeds the set height, the control unit 45 drives the storage box moving unit 66. The length of time for which the storage box moving unit 66 is driven is until the height determined based on the detection result of the upper paper piece detection unit 89 becomes less than the set height. Alternatively, the length of time for driving the storage box moving unit 66 may be a predetermined time set in advance.

When the number of processed sheets of paper P increases and the paper pieces J gradually accumulate up to the top of the paper piece storage box 65, the paper piece detection unit 68 detects the paper piece J even if the paper piece storage box 65 is vibrated for a predetermined time. Will not be resolved. At this time, the control unit 45 interrupts the processing of the paper P and displays an error message on the operation panel 46.

In the above embodiment, the storage box moving unit 66 has moved the paper piece storage box 65 in the same direction as the cutting direction of the cutting blade 36, but the storage box moving unit according to the present invention is not limited to this, and the cutting blade If the cutting direction is substantially the same as the cutting direction, the paper piece storage box may be moved in a different direction slightly shifted from the cutting direction of the cutting blade. In addition, the storage box moving unit 66 has moved the paper piece storage box 65 in the same direction as the conveying direction F, which is the cutting direction of the cutting blade 36 of the slitter mechanism 20, but the storage box moving unit 66 is capable of cutting other cutting blades. The paper piece storage box may be moved in substantially the same direction as the direction. For example, the cutting mechanism may be a cutter mechanism. In this case, the cutting blade is a cutter, and the cutting direction is the width direction. Further, although the cutting blades 24 and 36 cut the paper P in the width direction W and the transport direction F, respectively, the paper may be cut along an oblique cutting line with respect to the transport direction F.

The storage box moving unit 66 includes a carriage 71, a sliding contact plate 72, a width guide 73, and a movement drive unit 74. The carriage 71 includes a pedestal 76 and wheels 77, but other mechanisms such as springs, screws, cams, and the like. It is also possible to use a combination of these.

Further, although the side wall 64 is moved in the horizontal direction, the side wall 64 may be moved in the vertical direction. FIG. 7 shows a paper piece collection unit 23a having a storage box moving unit 66a in which the side wall 64 swings in the vertical direction. In the figure, the crank arm 83 a extends to the downstream side wall 64 of the paper piece storage box 65.

The crank arm 83a is formed in a U shape in cross section, and a bearing 93 is accommodated in the U shape. The bearing 93 is accommodated in the vicinity of the upstream end portion of the crank arm 83a. The bearing 93 is movable forward and backward in the U-shape while being guided by the crank arm 83a. Further, the bearing 93 is pivotally supported at a position spaced by a predetermined amount from the rotation center of the crank member 78a.

A swing base 91 is sandwiched and fixed between the pair of left and right crank arms 83a. A paper piece storage box 65 is placed on the swing base 91. The swing base 91 is pivotally supported by the support base 90 at the center in the transport direction F so as to be swingable.

When the motor 80a rotates, the crank member 78a is rotated by the connecting member 84a rotated via the drive gear and the driven gear 82a. Thereby, the bearing 93 moves the crank arm 83a up and down while moving back and forth in the crank arm 83a. Therefore, the swing base 91 swings as shown in FIG. 7B with the support base 90 as the swing center, and the paper piece storage box 65 is moved in the vertical direction.

Further, the side wall 64 is reciprocated a plurality of times between the direction separating from the paper piece J and the approaching direction, but may be moved only once in either the separating direction or the approaching direction. .

The various work setting information is manually set by the user from the operation panel 46 or automatically input by reading the barcode M2 by the reading unit 26, but communicates with an external information processing apparatus such as a personal computer. It may be set. Alternatively, a plurality of sheet arrangement patterns may be stored in advance in the storage unit by manual input from the operation panel, and each pattern may be called and set by a number or the like.

The processing apparatus 100 includes the slitter mechanism 20, the cutter mechanism 22, and the crease mechanism 21, but may be a processing apparatus including at least one of a slitter mechanism and a cutter mechanism. It is possible to apply the present invention to a processing apparatus in which a mechanism (including a perforation forming mechanism, a roundness forming mechanism, etc.) is appropriately combined, and further to a processing apparatus in which the number of processing mechanisms and transport roller pairs is different from that of the above embodiment Needless to say. Further, the sheet arrangement pattern is not limited to that illustrated in FIG. 4, and various other patterns can be set for the number of cutting lines S, K and folding lines C.

(Example)
Paper was processed using a paper piece collection unit 23 that can move in the horizontal direction shown in FIGS. 2 and 3 and a paper piece collection unit 23a that can move in the vertical direction shown in FIGS. The size of the paper piece storage box 65 was 650 mm in the conveyance direction length, 430 mm in the width direction length, and 330 mm in depth. Table 1 shows the maximum moving length of the paper piece storage box 65 in the horizontal or vertical direction, the time required for one reciprocating movement, the vibration state of the paper piece storage box 65, and the reduction ratio of the bulk of the paper pieces in the paper piece storage box 65. .

From Table 1, there was an effect of reducing the bulk of the paper pieces in the paper piece storage box by moving both the horizontal direction and the vertical direction of the paper piece storage box. Further, when the maximum movement length is the same, the ratio of reducing the bulk of the paper pieces in the paper piece storage box is higher in the horizontal movement than in the vertical movement. Very good results were obtained when the moving direction was horizontal and the maximum moving length was 40 mm.
