The conventional stacking device has the advantage that the leading end of the succeeding sheet 1 can be reliably inserted into the lower side of the trailing end of the stacking sheet 1a. There is. That is, the leading edge of the succeeding sheet 1 is the air nozzle 3
After passing through the sheet, since the lower surface receives air, the upper surface of the succeeding sheet 1 is pressed against the lower surface of the sheet 1a being laminated, and the friction resistance when inserting the subsequent sheet 1 is large. become. Therefore, when the sheet 1 is a paper having a weak stiffness, it is difficult to smoothly insert the subsequent sheet 1.

In particular, when the leading edge of the succeeding sheet 1 is in contact with the lower surface of the sheet 1a being stacked, the leading edge of the succeeding sheet 1 floats upward from the conveyor 2 and is pushed in from the rear side for insertion. There is a particular problem because you will have to go. In addition, the subsequent sheet 1 is the sheet 1a being laminated.
Since it is forcibly inserted by the transfer conveyor 2 while contacting with, the transfer conveyor 2 needs to be installed up to the stacking position A. Therefore, when carrying out the stacked sheets after stacking, it is necessary to carry out in a direction that does not interfere with the transport direction of the transport conveyor 2, or to provide a complicated transport mechanism so as not to interfere.

In view of the above conventional problems, the present invention can smoothly and smoothly insert a flat plate such as a paper having a weak stiffness, and is not restricted to carry out after the stacking. An object is to provide a flat body integrated device.

It is for ejecting air from the lower side to the lower surface of the.

Next, a stacking operation by the stacking device having the above structure will be described. The transport conveyor 6 continuously transports each sheet 5 in the arrow direction in an overlapped state in which the leading end side of the succeeding sheet 5 is inserted below the trailing end of the preceding sheet 5. Then, the preceding sheet 5 that has reached the end portion of the transfer conveyor 6 is pressed onto the transfer conveyor 6 by the pressing roller 9, so that the leading end thereof projects from the end of the transfer conveyor 6 toward the stacking table 7.

Then, since air is jetted from the upper air nozzle 10 and the lower air nozzle 11 to both the upper and lower surfaces of the sheet 5 , the preceding sheet 5 is slightly vibrated while the front end is held by the air. While moving to the accumulation table 7 side

You will be buoyant by Ah . Up and down like this
The air from each of the air nozzles 10 and 11 has a different function depending on the position of the seat 5, and thus the structure can be simplified as compared with the case where separate air nozzles are provided.

Moreover, since air is blown from both the upper and lower sides of the sheet 5, it is possible to suppress the generation of static electricity at the same time. Thereafter, in the same manner, the sheets 5 conveyed in the overlap state by the conveyor 6 are sequentially inserted into the lower side of the sheets 5 in the accumulating section and accumulated .

When a predetermined number of sheets 5 are accumulated in the accumulating portion on the accumulating table 7, the accumulating sheet 12 is carried out to the outside. In this case, air to the distal end side of each sheet 5 from above and below
It may be held by, away already from the transport conveyor 6
Collected sheets 5 by the sheet 5 on the conveyor 6 side.
Since it is sent to the stacking table 7 side, it is not necessary to install the transfer conveyor 6 over the stacking table 7. Therefore, the transport conveyor 6 and the stacking unit on the stacking table 7 are
Since the stacking sheets 12 can be arranged at intervals, the carry-out direction of the stacking sheet 12 is not restricted by the transport conveyor 6, and the stacking sheet 12 can be carried out in any direction, and the carry-out mechanism itself can be simplified.

The sheet (flat plate) 1 is not limited to paper or the like, and non-woven fabric or other material can be used in the same manner.
