DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet stacking and stacking apparatus suitably used for stacking a plurality of banded sheet stacks and providing the same for the next packing step.

[0002]

2. Description of the Related Art For example, a bill is a fixed number (for example, 100 bills).
) To form a sheet bundle, stack the sheet bundle in a fixed number of bundles (for example, 10 bundles) to form a flat stacking block, further apply the banding to the flat stacking block, and serially number the packing blocks. Is adopted. The same applies to securities, postcards, lotteries, and the like.

For example, a flat sheet stacking apparatus disclosed in Japanese Patent Application Laid-Open No. Hei 5-178520 discloses a side stacking means for controlling a side of a stack of sheets stacked on a stacking table. A plurality of accumulation stations are juxtaposed along the length of the elongated passage between the side rulers, that is, the passage defined by the side rulers and the loading table.

[0004] The sheet bundle is dropped between the both side ruler plates and is flatly stacked on a loading table. The loading table descends along the inner surface of the both side ruler plates as the flat stacking amount of the sheet bundle increases. Each stacking station forms a plurality of flat blocks.

[0005] Each of the flat stacking blocks is transferred along the passage in a state of being aligned in a row by a pusher running along the passage between the two side ruler plates, and one block is sequentially moved from the front end block to the passage end outlet. One by one,
After the discharge of the last block is completed, the flat stacking operation of the sheet bundle on the stacking table is started again.

[0006]

In the above-mentioned sheet stacking flat stacking apparatus, a plurality of flat stacking blocks are discharged one by one as described above, and after the discharge of all the flat stacking blocks is completed. Otherwise, the next flat stacking operation cannot be started, which is extremely inefficient and has a problem that it is difficult to respond to a demand for high-speed processing.

Further, since the stacking table is moved up and down along the inner surfaces of the pair of side ruler plates, the distance between the two side ruler plates cannot be reduced to less than the width of the stacking table. There is a problem that is difficult to deal with as appropriate.

If the distance between the two ruler plates is increased, a gap is formed between the stacking table and the ruler plate, and the edge of the lowermost sheet bundle cuts into the gap, causing damage to the sheets and trouble in the apparatus. .

Further, when each flat block is extruded by a pusher, the entire side surface of each block is rubbed over a relatively long process while being in contact with the inner surface of the side ruler plate. Is done.

The present invention is to solve these problems properly.

[0011]

Means for Solving the Problems As means for solving the above problems, the present invention comprises a first guide pin for regulating one side of the sheet bundle and a second guide pin for regulating the other side. A guide pin extends through the loading table and extends upwardly of the loading table. A plurality of the first and second guide pins are arranged in parallel along the length of the loading table. A second guide pin adjusting means which moves in a direction approaching and separating from the guide pins is provided to adjust the distance between the first and second guide pins.

[0012]

According to the present invention, a plurality of first guide pins and a plurality of second guide pins are arranged in parallel along the length of the loading table.

Accordingly, an entrance and an exit for each unit guide composed of the first and second guide pins are formed in a direction orthogonal to the longitudinal axis of the elongated loading table, and the flat stacking block group is simultaneously placed on the loading table through each of the outlets. Then, the next flat stacking operation can be started immediately, and the demand for high-speed processing can be met.

Further, since the first and second guide pins are configured to penetrate through the loading table, the second guide pins are moved in the longitudinal direction of the loading table to adjust the distance between the first and second guide pins. The interval between the first and second guide pins can be set to a smaller interval than the width of the loading table at any time without restricting the vertical movement of the loading table.

Further, since the first and second guide pins penetrate the loading table and move the second guide pins in the longitudinal direction of the loading table, the edge of the sheet bundle bites between each guide pin and the loading table. Such a harmful gap is not generated, and the entire lower surface of the flat stacking block is always stably supported, so that the flat stacking operation and the discharging operation can be smoothly performed.

Further, since each flat stacking block comes into linear contact with the first and second guide pins and is immediately discharged from the outlet between the first and second guide pins, damage due to rubbing between the flat stacking block and the side regulating means. Effectively prevent.
