In the arrangement pattern of the processed products Q shown in the drawing, four cutting lines K, two perforation lines Y, and two crease lines T along the sheet conveyance width direction are set on one sheet P. . From this, three unnecessary regions U are removed, and two processed products Q are manufactured.

[Work of processing equipment]
Using the operation panel 46 shown in FIG. 1, the user can use the size and type of the paper P, the number and size of the processed product Q, the cutting line, the perforation line, the crease line, etc. Various processing information relating to the position and length of the paper processing line is set. Note that the processing information can be automatically set by reading the barcode M2 or the like by the reading means 26 instead of the manual setting or in cooperation with the manual setting.

A plurality of sheets P stacked on the sheet feeding tray 2a of the sheet feeding unit 2 in FIG. 1 are supplied to the sheet conveying path 5 one by one from the upper end by the suction conveying belt mechanism 8a and the sheet feeding roller 8b. Then, the paper P is transported downstream on the paper transport path 5 by the transport rollers 9 to 17.

In the reading means 26, the position mark M1 of the paper P and the barcode M2 as necessary are read, and processing information to be applied to the paper P is set.

The rejection mechanism 25 operates on the paper P when the reading means 26 cannot read and the processing conditions are unknown or when there is a double feed, and the paper P is dropped and discharged. Collected by the tray 25a.

In the horizontal perforation forming mechanism 18, when the sensor 32 detects the front edge Pa of the paper P, the control unit 45 starts measuring the transport amount of the paper P in order to determine the formation position of the perforation line Y. Then, the control unit 45 synchronously drives each transport driving unit to transport the paper P by a predetermined amount, and sets the perforation line Y along the paper transport width direction W of the paper P at the installation position of the perforation forming blade 53. When the position to be formed has arrived, the transport drive units are stopped to stop transport of the paper P. Then, the control unit 45 drives the horizontal perforation forming drive unit to lower the perforation forming blade 53 and bring it into contact with the receiving member 54 via the paper P to form a perforation line Y at a predetermined position of the paper P. .

At this time, the lower roller 65 of the transport unit 11 installed on the immediate upstream side of the horizontal perforation forming mechanism 18 is a rubber transport member in which the paper sandwiching portion 67 that sandwiches the paper P is formed of rubber. In order to form Y, when the control unit 45 stops driving the transport driving unit and stops transporting the paper P, the paper P is firmly sandwiched between the upper roller 64 and the lower roller 65, and the proper position is reached. It can be stopped accurately. Therefore, it is possible to form the perforation line Y with high accuracy, and the sheet P is not slipped by the paper nipping portion 67 of the conveying member and the paper P is not excessively conveyed downstream, so that the perforation line Y is formed. The position does not shift.

Further, the control unit 45 starts measuring the transport amount of the paper P when the sensor 32 detects the front edge Pa of the paper P, and then when the paper P is transported by a predetermined amount by the rubber transport member of the transport unit 11, Since the perforation line Y is controlled to be formed on the paper P, the accuracy of the transport amount of the paper P can be further improved.

In the arrangement pattern of the processed products Q shown in FIG. 4, since the perforation line and the slit line along the paper conveyance direction F are not set, the vertical perforation forming mechanism after the paper P passes through the horizontal perforation forming mechanism 18. 19 and the slitter mechanism 20 and the paper piece dropping mechanism 27 pass through without any processing.

In the lateral crease forming mechanism 21, when the sensor 34 detects the front edge Pa of the paper P, the control unit 45 starts measuring the transport amount of the paper P in order to determine the formation position of the crease line T and the cutting line K. To do. Then, the control unit 45 stops the conveyance of the sheet P when the position where the crease line T along the sheet conveyance width direction W of the sheet P has reached the installation position of the upper mold 59 and the lower mold 60. To do. Then, the control unit 45 drives the lateral crease forming drive unit to lower the upper mold 59 and insert the convex portion of the upper mold 59 into the concave groove of the lower mold 60 via the paper P, so that the predetermined position of the paper P is reached. A crease line T is formed.

At this time, similarly to the formation of the perforation line Y in the horizontal perforation forming mechanism 18, the transport unit 15 installed on the immediate upstream side of the horizontal crease forming mechanism 21 holds the paper P of the lower roller 65. Since the portion 67 is a rubber conveyance member formed of rubber, when the control unit 45 stops driving the conveyance drive unit and stops conveyance of the paper P in order to form the crease line T, the paper P It can be stopped at an appropriate position by a strong frictional force. Accordingly, the crease line T can be formed with high accuracy, and the paper P does not slip and is not excessively conveyed downstream.

Further, when the paper P reaches the cutter mechanism 22, the position where the cutting line K along the paper conveyance width direction W of the paper P has reached the contact position between the upper movable blade 62 and the lower fixed blade 63. Thus, the control unit 45 stops the conveyance of the paper P. Then, the control unit 45 drives the cutting drive unit, lowers the upper movable blade 62, and contacts the lower fixed blade 63 via the paper P, thereby cutting the paper P at a predetermined position.

At this time, since the sheet holding portion 67 that holds the sheet P of the lower roller 65 of the conveyance unit 16 installed on the immediately upstream side of the cutter mechanism 22 is a rubber conveyance member formed of rubber, the control unit 45 performs the sheet conveyance. When the conveyance of P is stopped, it can be accurately stopped at an appropriate position. Therefore, the cutting line T can be formed with high accuracy.

Further, in addition to the immediate upstream side of the cutter mechanism 18, a paper clamping unit 67 that clamps the paper P of the lower roller 65 of the conveyance unit 17 installed on the immediate downstream side is a rubber conveyance member formed of rubber. Therefore, when cutting the paper P, the paper P can be held with a strong force both upstream and downstream in the paper transport direction by the pair of transport members. Therefore, it is possible to cut the paper P with high accuracy along the paper conveyance width direction W. Therefore, the upper movable blade 62 does not contact the lower fixed blade 63 during cutting, so that the position of the paper P does not deviate from the stop position, and the cutting line T is deviated from the paper conveyance width direction W. There is no such thing as being formed.

The unnecessary area U cut out from the paper P falls to the lower paper piece collection unit 23. The perforation line Y, the crease line T, and the cutting line K are respectively provided, and the obtained processed product Q is conveyed to the paper receiving unit 3 and stacked.

As described above, in the processing apparatus 100 according to the present embodiment, the processing for processing the paper P in the direction intersecting the paper transport direction F by the transport members such as the horizontal perforation forming mechanism 18, the horizontal crease mechanism 21, and the cutter mechanism 22. Some of the transport units 11, 15, 16, and 17 installed in the vicinity of the processing unit 24 are configured such that, among the pair of transport members, the transport member that is rotationally driven has the paper sandwiching unit 67 that sandwiches the paper P as the rubber. The other conveyance units 9, 10, 12, 13, and 14 are formed of a metal, and the sheet holding portion 67 of the conveyance member that is rotationally driven among the pair of conveyance members is formed of metal. Therefore, when processing the paper P, the paper P can be accurately transported and stopped, and the paper can be clamped by a transport unit using the metal transport member. 67 wear is suppressed. Therefore, durability can be improved.

In the above embodiment, the pair of conveying members is constituted by the upper roller 64 and the lower rollers 65, 66. However, the processing apparatus according to the present invention is not limited to this, and the installation direction of the conveying member is changed up and down. Alternatively, the belts may be opposed to each other in the lateral direction, or a belt may be used instead of the rollers. In addition, although the sponge roller is used as the conveyance member that forms a pair with the rubber conveyance member and the metal conveyance member, the sheet holding portion 67 of the pair of conveyance members may be formed of the same kind of material.

In addition, the rubber conveyance member is closer to the paper conveyance direction F than the horizontal perforation forming mechanism 18 and the horizontal crease mechanism 21 which are the processing unit 24 that processes the paper P in a direction crossing the paper conveyance direction F by the conveyance member. Although installed on the upstream side, the conveyance member of the conveyance unit installed on the further upstream side of the latest upstream conveyance unit may be a rubber conveyance member. Further, the horizontal perforation forming mechanism 18 may use the conveyance member on the most downstream side as a rubber conveyance member instead of or in addition to the most upstream side in the sheet conveyance direction.

Further, the control unit 45 starts measuring the transport amount of the paper P when the paper P is detected by the sensors 32 and 34 installed on the upstream side of the processing units 24. The transport amount of the paper may be measured based on the detection result of the sensor installed immediately downstream of the processing unit 24, and the position of the paper P may be determined based on the setting of the setting unit 47.

In addition, the lower roller 65 on both the upstream side and the immediately downstream side in the paper transport direction F of the installation position of the cutter blade 61 of the cutter mechanism 22 is a rubber transport member. A rubber conveying member may be installed only in the case.

The various processing information is manually set by the user from the operation panel 46 or automatically by reading the barcode M2 by the reading means 26. However, the external information that can communicate with an information processing apparatus such as a personal computer is provided. Information may be sent from the device and set. Alternatively, a plurality of arrangement patterns of the paper P may be stored in advance in the storage unit by manual setting from the operation panel, and each pattern may be called and set by a number or the like.

Needless to say, the processing apparatus 100 can be applied to a processing apparatus in which the configuration of each mechanism for processing a sheet is different from that of the above-described embodiment. Further, the arrangement pattern of the paper P is not limited to that illustrated in FIG. 4, and various other patterns can be set for the positions and numbers of cutting lines, perforation lines, crease lines, and the like.
