The paper separating device C has the following configuration (see FIG. 2).

That is, there is a separation unit connecting plate 50 connected to the positioning device B via the indexing unit 20, and an insertion air cylinder 51 fixed thereto allows the insertion head to be mounted by moving the plate 53 back and forth in the direction of arrow S-8. be moved. Guide 5
2a and 52b are for receiving loads. Insertion head mounting plate 5
A rising air cylinder 54 for moving the insertion head 56 up and down is fixed to 3. The guide 55a is for receiving a load. The insertion head 56 has a bellows 57 at its tip. The insertion head 56 separates the laminated paper 7 vertically at the marker 70 (FIG. 6C and FIG. 8) attached to the side surface of the laminated paper 7. An insertion head 56 is inserted.

Further, the tip of the vertical cutting plate 105, which is extended by the separation unit connecting plate 50, is bent, and a cylinder 106,

The delivery device consists of the following configuration (see Figure 1).
.

That is, the X-axis unit 22 in the positioning device B is located via the guide and slider in the X-axis unit 11.

This can be done without moving back and forth on the X-axis unit 11 by the air cylinder 23. (2) Fixed forks 24 and 24 are respectively coupled to the shaft unit 22. Only one of these fixed photos 24 and 24 is used at the same time,
The unused (fixed) j-rib 24 can be rotated horizontally by 90°, for example, and released so as not to interfere with the laminated paper 7 (FIG. 5).

(2) A screw 27 is attached to the shaft unit 22, and can be rotated by a movable fork drive motor 26. The movable fork 25 can be slid left and right from this point. FIG. 5 shows the situation when the laminated paper 7 is not fed out one ream. This will be explained below.

Figure a shows the state immediately before the start of operation.

The fixed fork 24 is rotated at 90° so that only the right fixed fork 24 is used, and the left fixed fork 24 does not function.
Manually rotate it in the horizontal direction so that it does not interfere with the laminated paper 7.

Conversely, depending on where the marker 70 is placed, only the left fixed fork 24 may function. Further, only the fixed flap 24 side that also uses the lower paper presser 28 functions.

The laminated paper 7 is separated by the insertion head 56 of the paper separating device C and fixed fork 24 . A movable folio 25 and a lower paper presser 28 can be inserted.

The figure shows a state in which the shaft unit 22 moves forward once by a certain stroke, and then the bottom paper presser 28 descends to press down the bottom paper.

Figure C shows a state in which the movable fork 25 has moved to the left.

In Figure d, the V-axis unit 22 is further advanced by a constant step,
This shows the state in which one rim has been sent out. During this time, the bottom paper presser 28 is kept pressed so that the bottom paper does not move.

The automatic paper feeder configured as described above is configured such that when the pallet 6 carrying the stacked paper 7 is moved to the conveyor 5'',
The pallet lifting device A operates and the lifter 1 rises.

Accordingly, sensor 1 of marker 70 ], marker 7 at sensor 1
When 0 is detected, the lifting of the lid 1 is stopped. Since this stopping operation is carried out by the pallet lifting device A, which weighs 1 to 25 tons, mere forced stopping cannot be put to practical use due to large variations in the stopping position.

Therefore, after detecting the marker 70 with the sensor 111, as shown in FIG.
As shown in FIG.
The servo motor 2 is controlled by the numerical control device 200 to switch the lifting operation of the lifter 1 by 1" to a numerically controlled deceleration operation, and to control the lifter 1 to stop at a certain distance from the detection position of the marker 70. (For example, the lifting operation of the lifter 1 is stopped 5 mm after the marker 70 is detected.)

Note that, by the numerical control device 200, the distance from when the sensor 111 detects the marker 70 to when the lid 1 stops rising remains constant even if the stacked paper on the lid 1 changes. FIG. 6a shows the state of the lifter 1 when it is raised 1" or stopped. In this state, as shown in FIG. 6C (FIG. 6C shows FIG. 6A in detail), the marker 70 is The upper paper is lifted up from the paper with the marker 70 on it, creating a gap, into which the bellows 57 and insertion head 56 are inserted to separate the upper ream containing the paper with the marker 70 from the ream below it. can be done. 6th
The figure shows a state in which the bellows 57 of the insertion head 56 are inserted between the stacks of paper 7. When the pallet 6 is stopped from rising, each time the marker 70 is detected, as shown in FIG. The counter 211 counts the slowness from the start of the ascent to the stop through the pulse generator 210, and the central processing unit 212 compares the counted value with the standard value and calculates the difference (ε= If 1 standard value - count value 1) is within the range of allowable values, it is considered normal, and if the difference is large, it is considered abnormal and a warning is issued and the lifting of the pallet 6 is stopped. This makes it possible to automatically detect printing errors of the marker 70 in the previous process.

When the lift 1 stops rising, the insertion head 56 can be inserted. This state is the state shown in FIG. 7a. Next, through the operations shown in FIGS. 6a and 6b, the state shown in FIG. 7 is reached.

Next, when the lifter 1 is raised, the insertion head 56 is also raised by the lifting force. The lifting operation of the lifter 1 stops when the next marker 70 is detected, but by supplying air to the lifting air cylinder 54 just before that, the insertion head 56 rises a certain amount further from that position and stops. . The state is shown in FIG. 7C, that is, the marker 70
The upper part of the fixed fork 24. of the delivery device is lifted. The movable flap 25 and the bottom paper presser 28 can be inserted between them. In order to send out 12 to 15 reams per minute, the insertion head 56 must be moved after the pallet 6 stops rising.
If the lifter 1 is inserted, the cycle time will not be in time for the bottom of the side, so the insertion head 56 is inserted before the lifter 1 rises, and when the lifter 1 stops rising, the marker 70 is already marked as shown in FIG. 7C. The upper part is further raised, allowing the delivery device to operate immediately, reducing cycle time.

In the state shown in Fig. 7C, the movable foot support 25 is moved in the direction away from the fixed fork 24 (Fig. 7d), and the bottom paper presser 28 is lowered to hold the bottom paper so that it does not move. One ream is sent out as shown in Figure 5d. - The blade insertion head moves from the state shown in FIG. 7 d to the state shown in FIG. 7 a, and proceeds to the next insertion operation.

By repeating this process, the reams can be wrapped one after another by the hand wrapping machine (
(not shown).

Effects of the Invention Since the present invention is configured as described above, it has the following effects.

Before the insertion head is inserted into the laminated paper, an air supply member with an air port for blowing air to the laminated portion of the laminated paper is provided, so that air creates a gap between the laminated papers in which the insertion head can be inserted. This method has the advantage of being able to effectively separate sheets of laminated paper into a predetermined number of sheets without using ream marker tape.
