A slide plate 82 is adapted to move via rollers 88, 88, . 84 is provided, and a support shaft 85 that protrudes from the slide plate 82 extends through the entire slit 84. A sprocket 86 and a boo IJ87 are provided at the front and rear of the horizontal support beam, and a chain 88 is wound between the sprocket 86 and the pulley 87.
8C is fixed to the front and rear ends of the slide plate 820. The sprocket 86 is rotated by an electric motor 89.

Phototubes 90.91 are attached to the front lower surface of the moving table and the front lower surface of the horizontal support beam 74, and these phototubes 90.91 detect the top surface of the stack of blank sheets on the pallet 92 placed in the stacking position. , the downward movement of the movable table 60 is stopped when the movable table 60 becomes flush with the upper surface thereof.

Next, the effect will be explained.

The uppermost bundle of packaged products placed on the lifter 8 is extruded onto the fixed table 15 by the extruder 2. At this time, as shown in FIG. 6, the grip 16 opens to hold the front end of the extruded packaged product.

When the packaged product located at the top of the mounting device 1 is delivered onto the fixed table 15, the detector 9 is activated and the lifter 8
is driven to raise the packaged product at the next highest position to the same level as the detector 9.

During this operation, the grip 16 is moved forward by the rodless cylinder 23, inviting 17 the extruded packaged product. At this time, the rotatable fourth regulation plate 32 provided between the fixed table 15 and the movable table 60 is raised to a vertical position as shown in FIG. , the grip 16tj moves the packaged product forward until the front end of the packaged product comes into contact with the grip 16tj. Next, the air cylinders 28 and 29 are activated to move the packaged product to the second regulating plate 25.
It is pressed in the Y direction in the figure by the regulating plate 26. At the same time, the air cylinder 30 is actuated to control the eighth regulation plate 2.
7 to press the top surface of the packaged product. The packaged products positioned by these position regulating devices 24 are then cut around the four circumferences of the wamp by a movable cutter device 34. At this time, cutter 40, 42, 45, 50i of each moving cutter
jliJ-Height is adjusted, and with L the wamp is divided into two halves, an upper part and a lower part.

Since the movable cutter along the 0 side and D side of the fixed table can also move in directions toward and away from these sides, the position of each rodless cylinder 43, 48 is determined depending on the size of the packaged product. When the rodless cylinder 43.48 approaches the side of the packaged product and the cutter 45.50 contacts the wamp, the limit switch 46.51 is activated and the air cylinder 47
．． 52 stops. Each rodless cylinder 43.
After the position of 49 is determined, each cutter 40.42.4
5. Move the 50 along the rodless cylinder and cut the wamp.

After cutting the wamp, each regulation plate 25, 27, 26
and 32 return to their original positions and the packaged product is released.

Thereafter, the delivery device 55 is activated to send the packaged product onto the moving table 60, and for this purpose the air cylinder 6
8 to lower the delivery plate 59. Next, when the rodless cylinders 56 and 56 are actuated, the delivery plate 59 sends out the rear end of the packaged product toward the moving table 60. At this time, soccer 61.61 is activated. This state is shown in Figure 8(b). When the sucker 61 starts to fully suck, the lower wamp is sucked by the sucker, and as the packaged product moves, the sucker 61 moves to the moving table 6.
Bend it in the 0 direction and work around this so that the front end of the lower wamp faces downward (.

Therefore, the front end of the lower wamp is positioned below the feed roller 62, and if the operation of the sucker 61 is stopped at this moment, the lower wamp will fall between the two tables 15 and 60. The stack of blank sheets covered by the upper wamp is sent out onto the moving table by the sending plate 59, and the feeding peak plate 59 moves the stack of blank sheets until the front end of the stack of blank sheets contacts the first stop plate 79 (FIG. 9). to move. When the stack of blank sheets stops on the moving table, the upper wump is removed by the upper wamp stripping device @68. That is, a vacuum source (not shown) is activated to attract the upper wamp by the sucker 66, and then the rodless cylinder 64 is activated to move the sucker 66 in the Y direction (to the left), and at the position outside the moving table. At this point, the suction of the sucker 66 is stopped. In this way, the upper wump is removed from the stack of blank sheets. Cylinder 7 when the upper wamp is removed
7.78 is actuated to raise the stop plate 79.82. Thereafter, the moving table 60 moves forward along the horizontal support beam 74 by the drive of the electric motor 89, and the movement continues until the front end of the moving table 60 comes into contact with a stop plate 75 attached to the front end of the horizontal support beam. . When the front end of the moving table comes into contact with the stop plate 75, the moving table stops, and then the air cylinder 78 is activated to move the second
The stop plate 80 is lowered.

Thereafter, the screw shafts 71 and 71i are driven to lower the movable table 60. At this time, the phototubes 90 and 91 attached to the moving table 60 and the horizontal support *74 detect the top surface of the stack of blank sheets 7'L stacked on the pallet 92, so both phototubes 90 and 91 detect the top surface of the stack of blank sheets. When the top surface is reached, the movement table 6o stops descending.

In this state, when the movable table 6o is moved to the rear side along the horizontal support beam 74, the stack of blank sheets placed on the upper button of the movable table 60 is moved by the second stop plate 80. Directional movement is restricted 11, top surface of blank paper stack K11+1! will be placed. As these trough operations are repeated, the stacks of blank sheets from which the wamps have been removed are stacked one after another on the pallet 92.

In addition, in the present invention, the wump is removed from the top and bottom of the stack of blank sheets using a wamp stripping device that has separate upper and lower parts of the wamp, but after cutting the wump with a movable cutter device, the wamp is turned over. It is also possible to install a machine, first remove the upper wamp, then reverse the whole stack of blank sheets to move the wamp on the back side to the front side, and then use the same wamp stripping device to remove the wump that was reversed to the front side. ↓Yes.

Since the present invention is configured as described above, it is possible to mechanically perform the work of cutting the wrapping paper with a knife and the loincloth work 1, which requires a very high labor burden (and takes a long time) for the worker. This can have an extremely large effect on labor saving.
