Abstract

PROBLEM TO BE SOLVED: To accumulate only unit paper in a group unit by providing a control part for suspending a drive of a cutting part upon recognizing a grouping unit while continuing a belt conveyance of a delivery stacker part to stack unit paper in the grouping unit and suspending the cutting of paper at the time when the unit paper is cut in the grouping unit. SOLUTION: Continuous paper 1 is cut into unit paper 2 by allowing a blade 13 to contact a perforation machine. Then the number of sheets of paper is counted with a paper counter 32 at the time of cutting the paper. Next, the unit paper 2 is conveyed to a delivery stacker part 26 by pressing overlapping surfaces with each other. At this time, the number of sheets of paper is counted with the paper counter 34. When the paper counter 32 counts the sheets of paper up to a predetermined number, the unit paper in the predetermined number is fed to a pressing rotor 16 to suspend the cutting of the paper. Subsequently, when the predetermined number is counted by the paper counter 34, the operation of the conveyance roller 34 and the like is also suspended. Consequently, only the unit paper in the predetermined number is subsequently conveyed and accumulated.

Following the carry-out roller 33, there is provided a delivery stacker section 26 for sequentially stacking the unit paper sheets P2 whose overlapping surfaces are pressure-bonded, and this delivery stacker section 26 is provided.
Is equipped with a belt conveyor 26a which is a belt transfer mechanism. The delivery stacker portion 26 has one end rotatably supported by a support shaft 27 provided on the upper cover 31, while the other end is pivotally attached to a support arm 28 supported by the machine body 1 and the support arm 28 is folded. By making it possible, it can be displaced horizontally (in the state of FIG. 1) or in the inclined state during operation and in the vertical state during standby. Further, a guide plate 36 is provided on the pivot end side so that the unit sheets P2 transported by the belt conveyor 26a are stacked in a vertical state.

A sheet counter 34 for counting the number of unit sheets P2 is arranged above the end of the belt conveyor 26a on the side of the carry-out roller 33. Further, a paper counter 32 for counting the number of unit sheets P2 is arranged between the high speed roller 12 and the blade 13 at a position corresponding to the conveyance path of the unit sheet P2. The paper counters 32 and 34 form a paper counting unit. The count signals of the paper counters 32 and 34 are also input to the control unit 19. In addition,
The sheet counters 32 and 34 and the storage unit 21 constitute a sorting unit identification unit.

Further, the machine body 1 is provided with a manual on / off switch 35 for on / off controlling the operation of the drive motor 18. The on / off signal of the on / off switch 35 is also input to the control unit 19.

On the other hand, casters 29 are provided at four corners on the lower surface of the machine body 1 so as to be movable,
Inside each of the casters 29 on the front side, a fixing member provided with a grounding body 30 which is made of rubber and presses the floor surface by a screw mechanism is provided. Although this fixing member is provided only on the front side, the grounding body 30 is made of rubber and is deformable, so that the machine body 1 is installed in a horizontal and stable state to prevent movement by the casters 29.

Next, the operation of the present embodiment configured as described above will be described. First, description will be made regarding a case where a predetermined number of sheets, for example, 30 sheets, is used as a sorting unit. When the number of sorting units “30” is input from the input unit 20, the vertical spacing between the pair of pressure rollers 16 and the top and bottom of the unit sheet P2 are set. Data such as an appropriate processing speed according to size, paper thickness and the like is also input from the input unit 20 and stored in the storage unit 21.

Then, the paper placing table 5 on which the continuous paper P1 is placed in a predetermined folding state is set on the paper folding device 3 by its supporting arm 6, and the continuous paper P1 is passed through the paper folding device 3 to a predetermined folding condition. The sheets are superposed and guided to the guide plate 7, and further, the marginal holes of the continuous paper P1 are fitted into the pins of the tractor 8 and set in a predetermined state.

When the main switch (not shown) is turned on, the drive motors 17 and 18 are driven, the continuous paper P1 is transported by the tractor 8, the marginal portion is cut and removed by the marginal slitter 9, and While being transferred to the high speed roller 12 via the infeed roller 11, the cut marginal portion is stored in the marginal storage portion 10. The continuous paper P1 is nipped by the infeed roller 11 and the high speed roller 12,
When tension is applied due to the difference in transfer speed, the blade 13 comes into contact with the horizontal perforations of the continuous paper P1 and breaks the horizontal perforations, and the continuous paper P1 becomes the unit paper P2. At the time of this cutting, the paper counter 32 counts the unit paper P2.

The unit paper P2 is conveyed by the conveyor belt 14, passes through the idler roller 15 and reaches the pressure roller 16, where a predetermined pressure is applied from above and below, and the overlapping surfaces are pressure-bonded. Unit paper P2 with the overlapping surface pressed
Are carried out to the belt conveyor 26a by the carry-out roller 34, sequentially transferred to the guide plate 36, and guided by the guide plate 36 to be accumulated vertically. Even when the unit paper P2 is carried out to the belt conveyor 26a,
The sheet counter 34 counts.

When the number of unit sheets P2 counted by the sheet counter 32 reaches "30", the control signal from the control section 19 causes the 30th unit sheet P to be counted.
After 2 is sent from the conveyor belt 14 to the pressure bonding roller 16, the drive motor 18 is stopped and the new cutting operation is stopped. When the sheet counter 34 counts the thirty unit sheet P2, the control signal from the control unit 19 causes the drive force transmission system of the drive motor 18 to shut off the drive force transmission system for the pressure roller 16 and the carry-out roller 33. Then, the operations of the pressure roller 16 and the carry-out roller 33 are also stopped.

Therefore, only the unit sheet P2 of 30 sheets, which is the designated sorting unit, is positioned on the belt conveyor 26a, and the unit sheets P2 sequentially transferred in the direction of the guide plate 36 are vertically arranged by the guide plate 36. Accumulated in
It is divided. If each unit sheet P2 in this stacking state is taken out, the 30 unit sheets P2 are divided.
Can be obtained. Then, when the on / off switch 35 is turned on, the drive motor 18 is driven again, the driving force transmission system for the pressure roller 16 and the carry-out roller 33 is connected, and the above-described operation is repeated.

Next, a case will be described in which the sorting is performed for each sorting unit by the sorting mark (not shown) provided on the unit paper P2. In this case, the mark sensor for reading the division mark is replaced with the above-mentioned paper counters 32 and 34 and arranged at the same position, and when the continuous paper P1 is cut into the unit paper P2, the division mark is read and When the final unit paper P2 is detected, the drive signal of the drive motor 18 is stopped after the detected final unit paper P2 is sent from the conveyor belt 14 to the pressure roller 16 by a control signal from the controller 19. The cutting operation stops. Then, when the mark sensor provided corresponding to the belt conveyor 26a detects the final unit paper P2 of this sorting unit, the drive motor 18 is controlled by the control signal from the controller 19.
In the driving force transmission system, the driving force transmission system for the pressure roller 16 and the carry-out roller 33 is shut off, and the operations of the pressure roller 16 and the carry-out roller 33 are stopped.

In this way, only the unit paper P2 of one sorting unit designated by the sorting mark is conveyed by the belt conveyor 2
The unit sheets P2, which are positioned on the sheet 6a and are sequentially transferred in the direction of the guide plate 36, are vertically stacked and sorted by the guide plate 36. By taking out the unit sheets P2 in this stacking state, it is possible to obtain the divided unit sheets P2. Then, when the on / off switch 35 is turned on, the drive motor 18 is driven, the drive force transmission system relating to the pressure roller 16 and the carry-out roller 33 is connected, and the same sorting operation is repeated.

Further, in the above-described series of processing and sorting operations, when a unit paper P2 whose overlapping surfaces are not adhered due to a jam or the like is generated or only one unit paper P2 needs to be adhered, the upper cover is formed. When the lid 22 of 31 is opened, the open state is detected by the detection switch 24, and if the drive motors 17 and 18 are being driven, the control unit 1
This is stopped by 9. Here, the unit paper P2 is inserted along the insertion guide plate 23, and the pair of pressure rollers 1
When it is sent toward 6, the paper sensor 25 detects the unit paper P2 and sends a detection signal to the control unit 19 to cause the control unit 1
The control signal from 9 starts the drive motor 17. Therefore, the pair of pressure rollers 1 are attached to the unit paper P2.
A predetermined pressure is applied by 6 and the superposed surfaces are pressure-bonded and transferred to the delivery stacker unit 26.

The present invention is not limited to the above-described embodiment. For example, the continuous paper P1 may be folded in two, not only in three folds, but also in two folds. You can also use it. In addition, the bonding state of the overlapping surfaces may be such that the entire surface is bonded, or a part of the peripheral surface or one side, such as an envelope or a booklet, is bonded. Then, the sheet folding device 3 having a configuration corresponding to this folding operation is used, and in the case of cutting and stacking, the sheet folding device 3 is not necessary. Further, the segmenting operation does not necessarily have to be performed in combination with the crimping operation.

Further, the on / off switch 35 may be configured to be turned on / off automatically instead of manually. For example, it is automatically turned on after a predetermined time (for example, 10 to 15 seconds) set after the end of the classification. It may be configured to operate, or may be configured to automatically turn on after a predetermined time (for example, 2 to 3 seconds) set in advance after taking out the unit sheets P2 in the stacking state.

As is clear from the above description,
According to the invention described in claim 1, the operation of dividing the unit sheet obtained by cutting the continuous sheet is stopped at the time when the unit sheet of the unit of dividing is cut, and the delivery stacker unit displays the operation of dividing the unit sheet. Since only unit sheets are collected,
This has the effect of enabling reliable division.

According to the invention described in claim 2,
It is possible to reliably perform the sorting operation for each constant number of sheets.
