Further, a guide plate 44 is provided above the transportation path of the accumulated banknotes. This guide plate 44 is indicated by an arrow (e)-(f).
It is arranged along the direction, and for example, the lower surface thereof slides on the banknotes stacked on the transfer plates 35 and 36 so as to prevent the banknotes from being disturbed when the banknotes are conveyed. It has become.

Next, the steps for accumulating banknotes in the sorting unit 12 and bundling the banknotes in the bundling unit 13 will be described with reference to FIGS.
It will be described with reference to the drawings.

The banknotes sent through the transport path M ₂ are sent to the stacking position 23 and then hit by the knock-off forks 26 on the upper surface of the banknotes, so that the banknotes are placed on the placing plate 25 waiting to rise to the position indicated by the solid line. They are stacked and placed one by one.

When 100 banknotes are accumulated on the mounting plate 25 (based on the timing sensor 24 detecting the passage of the trailing edge of the 100th banknote), the mounting plate 25 is shown in FIGS. 2 and 3. These 100 stacks of banknotes descend to the position indicated by the chain double-dashed line.
A transfer plate 35 that was previously waiting under the mounting plate 25
Delivered to 36.

In parallel with this, the 101st and subsequent bills sent through the transport path M ₂ are rotated in the arrow (c) and arrow (d) directions simultaneously with the lowering of the mounting plate 25, and are then placed in the stacking position 23. It is temporarily collected on the placed sorting forks 27 and 28 (shown by the chain double-dashed line). That is, even when the mounting plate 25 has left the stacking stack 23, the feeding and stacking of banknotes through the transport path M ₂ is continued without any timing change.

Here, since each rotation of the division forks 27/28 in the arrow (c) and arrow (d) directions is performed in parallel with the descent of the above-mentioned storage 25, the division forks 27/28 are
Of the forks 27 and 28 when rotating the
The support surfaces 27C and 28C, which are lower surfaces of the banknotes, press the upper surface of the banknote stack, thereby preventing the banknote stacking state from being disturbed by movement.

Further, when the division forks 27, 28 are rotated and arranged as shown by the chain double-dashed line, these division forks 27, 28
It is assumed that the support surfaces 27C and 28C of 28 are in contact with or pressed against the upper surface of the banknote stack.

With the mounting plate 25 at the position shown by the chain double-dashed line in FIGS. 2 and 3, the transfer plates 35 and 36 and the delivery plate 37 advance in the direction of arrow (e). At this time, the delivery plate 37 presses the accumulated banknotes on the mounting plate 25 in the arrow (e) direction, so that the accumulated banknotes are moved on the mounting plate 25, and the transfer plates 35 and 36 are transferred. Get down.

Here, the support surface 27C / 28C on the lower surface of the sectioning fork 27/28
Is used as a guide when the accumulated banknotes move in the arrow (e) direction.

Then, after this, the transfer plates 35 and 36 further advance in the direction of the arrow (e) with the stacked banknotes placed thereon, and further the binding portion 13
When it moves to a position close to the holding plates 14A and 14B, one of the transfer plates 36 stops and the other transfer plate 35 (not shown) as shown by the chain double-dashed line on the left of FIG. And only the delivery plate 37 moves forward. As a result, in a state where the accumulated banknotes are partially supported, the stacked banknotes are guided between the sandwiching plates 14A and 14B, sandwiched by the sandwiching plates 14A and 14B, and the movable portion 40 that supports the delivery plates 35 and 36 and the delivery plate 37 is bound. When returning from the section 13 to the organizing section 12, the banding process is performed by banding.

On the other hand, when the accumulated banknotes are guided and sandwiched between the sandwiching plates 14A and 14B, the accumulated banknotes are concave upward (convex downward) along the shape of the sandwiching plates 14A and 14B. One of the delivery plates 35 is retracted downward by the accumulated banknotes so as not to hinder the operation.

In parallel with the above steps, the transfer board for the accumulated banknotes
The mounting plate 25, which has been emptied after being transferred to 35 and 36, moves upward and is placed at the position shown by the solid line in FIG. At this time, since the sorting forks 27 and 28 on which the 101st and subsequent stacked banknotes are temporarily stacked are formed in comb teeth as shown in FIG. Can be inserted into these dividing forks 27 and 28 without any trouble.

Division forks 27 and 28 are in the arrow (c) direction, arrow (d)
The bills, which are temporarily accumulated on the sorting forks 27 and 28, are delivered to the placing plate 25 by rotating in the respective directions, and thereafter, are placed at the standby position shown by the solid line.

At this time, when the partitioning forks 27/28 rotate, the rotation of the partitioning forks 27/28 is not hindered by the presence of the mounting plate 25 for the same reason as described above.

Hereinafter, the steps from to are continuously performed to sequentially create a banknote bundle.

As described in detail above, according to the paper sheet stacking and conveying apparatus shown in the embodiment of the present invention, when the sorting forks 27 and 28 enter the bill stacking position 23, they are formed on the lower surface of the sorting forks 27 and 28. Since the supported surfaces 27C and 28C are configured to press a predetermined number (100) of banknotes stacked and mounted on the mounting plate 25, when lowering the mounting plate 25, The stacking state can be prevented from being disturbed, and the bills can be transported smoothly (see the process).

Further, since the supporting surfaces of the sorting forks 27 and 28 are in a positional relationship of pressing the upper surface of the banknotes having a predetermined number of stacked banknotes, after the mounting plate 25 is lowered, the mounting plate 25 is further lowered. When the upper banknotes are collectively moved horizontally (plane direction), the support surfaces 27C and 28C of the sorting forks 27 and 28 can be used as guides for horizontally guiding the banknotes. As a result, it is possible to smoothly guide the stacked bills to the bundling unit 13 (see the process).

Further, a sorting fork 27 for temporarily accumulating banknotes exceeding the predetermined number (the 101st banknote and thereafter) on the supporting surfaces 27C and 28C.
Since it is provided on the lower surface of 28, as a result, this sorting fork 27/28 can have at least two functions: a function of temporarily stacking and placing banknotes and a function of pressing or guiding banknotes. . As a result, there is an effect that the device is not complicated and the entire device can be relatively downsized.

[Advantages of the Invention] As described in detail above, according to the present invention, when the sorting fork enters the sheet stacking position, the supporting surface formed on the lower surface of the sorting fork is on the receiving plate. Since a predetermined number of stacked sheets are pressed, it is possible to prevent the stacking state of the sheets from being disturbed when the receiving plate is lowered, and to smoothly transport the sheets. It can be carried out.

Further, since the supporting surface of the sorting fork is in a positional relationship of pressing the upper surface of a predetermined number of stacked sheets, after lowering the receiving plate, the sheets on the receiving plate are further removed, for example. When trying to move horizontally (plane direction) collectively, the supporting surface of this sorting fork can be used as a guide for horizontally guiding the paper sheets, and the guide can be performed smoothly. The effect of being able to do is obtained.

Further, since the supporting surface is provided on the lower surface of the sorting fork for temporarily accumulating the paper sheets exceeding the predetermined number sent through the transport path, as a result, the paper sheets are temporarily accumulated on the sorting fork. It is possible to provide at least two functions, that is, a function of placing and a function of pressing or guiding the paper sheets. In other words, since the function of pressing or guiding the paper sheets could be incorporated into the existing sorting fork, as a result, the device was not complicated even though the function was increased, and the entire device was relatively The effect that it can be miniaturized is obtained.
