Description

Detailed Description of the Invention This invention aims to remove the distortion of the end surface that occurs during cutting by pulling out a bundle of small pieces of predetermined dimensions (e.g. postcards) from a stack of sheets into multiple rows and columns from a cutting machine. The present invention relates to a stacking device for stacking stacks of small paper sheets, which is capable of modifying the above-mentioned paper stacks and then transshipping the stacks of paper sheets having multiple rows and columns into a predetermined number of stages.

Conventionally, the work of pulling out the cut stack of paper sheets from a cutting machine, correcting the distortion of the cut end face, and transferring the stack of paper sheets to a predetermined number of tiers was all done manually, which was extremely inefficient. It was hot.

The present invention is based on mechanizing such conventional manual work procedures, and its configuration is such that a stack of paper sheets cut into multiple rows and columns is pulled out from a cutting machine to a predetermined position and transferred to the next order. A discharge transfer trolley section A, and a transfer trolley section B for transferring check paper bundles one row at a time from the discharge transfer trolley section A to the next rank.
Then, a correction cart part C corrects the distortion of the end face of the paper bundles transferred one row at a time from the transfer cart part B, and the paper bundles corrected by the correction cart part C are transferred again in many rows and in many columns. Aligning cart part D for aligning
and a transshipment section E that transships stacks of paper sheets arranged in a plurality of rows and columns in a sorting cart section D into a predetermined number of stages.

Next, the configuration will be explained with reference to an embodiment shown in the drawings.

FIG. 1 shows a discharge transfer truck section A. This discharge transfer truck section A has rollers and can run on the table from the cutting table 1 toward the air table 2. It is designed to move forward or backward by forward or reverse rotation of a feed screw 4 attached to the frame 3, and the rotation of the feed screw 4 is performed by a drive mechanism of a gear 5, a worm reducer 6, and a pole change motor 7. ing.

The discharge transfer cart A also has a discharge arm 8 that can come into contact with the rear end of the small paper sheet P, and an air cylinder 9 that brings the discharge arm and 8 into and out of contact, and the discharge arm 8 is connected to the cutting table 1. When the air cylinder 9 is perpendicular to the plane shown in the figure (the rod is retracted) and the paper stack P is sent forward, it can come into contact with the rear end surface of the paper stack P, and the paper stack P can be moved forward. P is discharged by rotating the feed screw 4.

In the above, the paper bundle P is cut into many rows and many columns by the cutting machine 10 as usual, and when the discharge transfer cart A returns backward (moves to the left), the discharge arm 8 is moved to the air cylinder 9. It can be raised above the table surface so that the discharge arm 8 can be raised to a position where it does not come into contact with the stack of paper sheets P when the discharge transfer cart A is retreating. Note that the discharge transfer table A is moved back by reverse rotation of the feed screw 4.

The discharge transfer cart A can move forward to position A' in correspondence with the feed screw 4 when transferring the small paper bundle P, and moves the small paper bundle P from the cutting table 1 to the air table 2.
Eject and transfer to the side to position P ¹ . The transfer trolley section B receives the paper bundle P discharged forward by the discharge trolley section A and corrects it by receiving it in one row using the paper bundle receiving section 11 consisting of a horizontal stand and an inclined plate of the trolley section B. This transport vehicle part B has rollers 13 and seesaw bases 14 that move within channel-shaped guide rails 12 installed opposite to each other in both the front and rear regions.
It has a rack 16 that meshes with the gear 15 on the side, the sheet bundle receiving part 11 is slightly inclined forward, and the upper surface of the receiving part is arranged forward and slightly lower than the two surfaces of the air table. As shown in the figure, in the backward state, the transfer cart section B is in a relationship such that it can receive one row of paper bundles P each time the paper bundle P is discharged forward in one row by the discharge cart section A.

On the other hand, the seesaw table 14 has a support shaft 17 pivotally attached to the rear part of the frame portion that holds the guide rail 12, and the upper surface of the tip of the seesaw table can swing up and down by an air cylinder 18 connected to the lower front part. A rack 19 that engages with the gear 15' that rotates the gear 15, and an air cylinder 20 that moves the rack 19 are attached to the rack.

Therefore, the seesaw table 14 moves the transfer carriage B back to the illustrated position by the return of the air cylinder 20, and also maintains the transfer carriage B in a horizontal position by raising the air cylinder 18. Bring the rear end of the top surface of the horizontal table into contact with the front end of the air table 2,
Next, when the motor 7 is driven and the feed screw 4 is rotated to move the discharge transfer cart A forward a distance corresponding to one row of check paper bundles P, that is, one pitch, the frontmost row of check paper bundles P is moved to the air table. From 2, the paper sheet stack receiving section 11
It is delivered to the horizontal platform of.

After the above delivery, in synchronization with this, air cylinder 2
0 and has a sheet bundle section 11.
is pulled forward along the guide rail 12, and the check paper bundle P is transferred to the rear of the table 21 of the table correction cart section C. Thereafter, when the air cylinder 18 is driven in the downward direction to lower the seesaw table 14 using the support shaft 17 as a fulcrum, the transfer trolley B and the paper bundle receiver 11 are simultaneously lowered and the small paper bundle P ₃ is lowered.
is left on the upper surface of the rear end of the table 21. As will be described later, the rear end of the table 21 has a cutout structure corresponding to the sheet stack receiving section 11, so that the sheet stack receiving section 11 can pass downward.

Next, the transfer cart B is moved back to the old position by the backward operation of the air cylinder 20, and then the seesaw table 14 is returned to the horizontal position by the drive of the other air cylinder 18, and one cycle of movement of the transfer cart B is completed.

The correction truck section C serves to correct the distortion of the end faces of the paper bundles _P3 sent one row at a time from the transfer truck section B, and then transfer them to the alignment truck section E. Here, the correction truck section C can move forward and backward along the guide rail 23 by means of an air cylinder 22 provided on the pedestal 3, and the table 21
The ends of the paper bundle P ₃ placed on the upper surface of the rear end are moved forward by the transfer arm 24, and the edges of the paper bundle P ₃ are aligned.

In the above transfer, the paper bundle is sent to the _P4 position, and the transfer arms 24 and 25 are moved to the air cylinder 2.
4' and 25', and the correction truck part C is repeatedly moved intermittently to move back and return to the position shown in the figure.
One of the transfer arms 25, which is formed by descending again at the timing until the next transfer of the paper bundle _P3 by the transfer arm 24, is located at the rear end of the paper bundle _P4 . air cylinder 26 when
The correction stopper 27 is rotated upward by the intermittent drive and comes into contact with the front end of the paper bundle _P4 , thereby aligning the paper bundle _P4 back and forth.

Note that the rear end of the table 21 (the position where the paper bundle _P3 is placed) has a cutout structure corresponding to the paper stack receiver 11 so that the paper stack receiver 11 can pass downward, and The tip of the table 21 has a notch structure corresponding to the correction stopper 27 so that the correction stopper 27 can pass upward therethrough.

Also, the top surface of this table 21 is the transfer arm 2.
4 and 25 have grooves through which they can pass through in sliding contact with each other, and when the correction cart section C moves forward, the paper bundle P ₄ whose end face has been corrected is aligned by the transfer arm 25 and transferred to the cart section. They are sequentially transferred to the air table 28 at D.

The alignment truck part D is a part that re-aligns the stack of paper sheets _P5 corrected and transferred one column at a time from the correction truck part C into multiple rows and columns, and the alignment truck 29 has a pinion gear 30, This pinion gear is
By rotating it in the opposite direction, it runs back and forth on the rack 32 provided on the pedestal 31. Rotation of the pinion gear 30 is provided by driving a brake motor 34 via a worm bundle reducer 33.

The alignment truck 29 also has an alignment transfer arm 35;
The transfer arm is made horizontal and vertical by actuation of an air cylinder 36 supported by the alignment truck 29. Note that an end face alignment stopper 37 is fixed to the most distal end of the pedestal 31 with respect to the transfer arm 35.

On the other hand, side plates are provided in both areas of the table 21 and the pedestal 31, and both end faces of the bundle of paper sheets that are sequentially transferred forward are corrected in correspondence with the side plates, and the side plates are connected to adjustment bolts. It is set so that the corresponding interval position can be adjusted. 38 is a reloading plate which will be described later.

Then, the brake motor 34 is driven to reversely rotate the pinion gear 30, and the alignment cart 29 is retreated along the rack 32 to the rear end of the air table 28, and then the air cylinder 36 is operated. The alignment transfer arm 35 is made vertical and brought into contact with the rear end surface of the Sho-kirigami leaf bundle _P5 being transferred to the air table 28 by the correction cart section C. At this time, the air cylinder 36 is configured to operate when the stack of paper sheets _P5 is in one row on the air table 28 or when a specific number of rows (for example, three rows) are formed.

Next, the brake motor 34 rotates the pinion gear 30 in the forward direction to move the alignment cart 29 forward, and the alignment transfer arm 35 transfers one row or a specific number of rows of small paper bundles P ₅ to one of the small paper bundles. The transfer plate 38 is moved from the air table 28 to the position where the front end surface contacts the end face alignment stopper 37, that is, the position of the small paper bundle _P6 .
Transfer to the side.

Here, the alignment cart 29 is stopped by a limit switch (not shown) activated by a brake when the front end surface of the stack of paper sheets P ₅ in one row or a specific multiple rows comes into contact with the end surface alignment stopper 37. The drive of the motor 34 can be stopped.

Next, the air cylinder 36 is moved back and returned, the alignment transfer arm 35 is rotated upward, and the transfer arm 35 is moved horizontally to move the brake motor 3.
4, the pinion gear 30 is reversely rotated, and the alignment truck 29 is moved backward and returned to its original position. This stroke completes one cycle of movement of the alignment cart 29.

In the above, one row or multiple rows of check paper sheets P ₅
The front end surface of is brought into contact with the end surface alignment stopper 37 in the first movement cycle of the alignment cart 29,
In the second and subsequent movement cycles, the paper bundles P ₆ , P ₇ . 29 is in a running relationship in which a limit switch (not shown) operates to stop the brake motor 34 when the number of lines in the transfer reaches a predetermined number.

Furthermore, a stack of paper sheets with multiple columns (for example, 5 rows x 11 columns) is divided into two or more groups of multiple rows and columns (for example, cases of 5 rows x 6 columns and 5 rows x 5 columns). When it is desired to align the first group (for example, five rows), a secondary end face alignment stopper 40 that is movable in the vertical or horizontal direction by the operation of the air cylinder 39 is provided in the middle as shown in FIG. 1B. x6 rows) of check paper sheets
After transferring and aligning P ₆ and P ₇ , the air cylinder 39 is operated to make the secondary end face alignment topper 40 vertical, and by repeating the movement cycle of the alignment cart 29 as described above, the second group (for example, 5 rows x 5 columns) may be transferred and aligned.

In the above case, the transshipment plate 38 must also be divided into two or more groups, as described below.

In this way, the distortion of the end face of the stack of small paper sheets cut into multiple rows and multiple columns is corrected by repeating the movement cycle of the alignment cart 29, and then transferred and aligned again onto the transfer board 28 into multiple rows.

The transshipment E is a section for transshipping the stacks of paper sheets P ₆ , P ₇ .

Here, the transshipment board 38 consists of opening/closing plates 38a and 38b divided symmetrically on the left and right, and the opening/closing plate 3
8a and 38b each have a roller 42 and a rack 43 symmetrically in the front and back, and the roller 42 slides on a guide rail 45 supported by a pedestal 44, and the opening/closing plate 38a,
38b relatively opens and closes in the direction of the guide rail 45 via the rollers by the rotation of the pinion 46.

A rotating shaft 47 of the pinion 46 is supported by the frame 44 via a flange unit 48.
The rotating shaft 47 is connected to an air motor 50 via a gear 49.
It is configured so that it can be rotated.

Therefore, the operation of the transshipment section E begins with the air motor 5.
0 to rotate the pinion 46 in the forward direction, move the rack 43 to close, and close the opening/closing plate 38 of the transfer plate 38.
a and 38b are closed. Next, the stacks of paper sheets P ₆ , P ₇ , etc. are placed on the transfer plate 38 closed by the alignment cart D.
After arranging the plates into multiple rows and matrices, the air motor 50 is driven to reversely rotate the pinion 46 and move the rack 43 in the direction of opening the transshipment plate.
8a and 38b are opened in both areas along the guide rail 45. Then, the stacks of check paper sheets arranged in many rows and many columns fall vertically without breaking, and the pallets 41 placed on the table lifter 51
transshipped to the top.

In this way, one cycle of movement of the transfer section E is completed, and by repeating this cycle, it is possible to transfer the stacks of paper sheets arranged in many rows and many columns to the desired number of stages, and If it is desired to divide a stack of paper sheets with many rows and columns into two or more groups, a plurality of the above-mentioned units including the transfer plates 38 may be provided in a column.

Note that the stack of paper sheets transferred to the desired number of stacks is lowered down the pallet 51 and transferred to, for example, a belt conveyor 52.
This can be done appropriately by discharging the waste and transferring it to the next process.
