Abstract

PURPOSE:To stack and deliver sheets stably by moving the position of a guide means when stacking operation is switched to delivery operation or vice versa, and by moving the protruding position of an endless belt. CONSTITUTION:Sheets 1 are stacked stably and well aligned by an endless belt 5, which is retracted with movement of pressure rollers 6a, 6b when the stacking operation is to be changed over to the delivery operation or vice versa. This does not cause heaving of the endless belt 5 when a carrier 23 rises, and the sheets 1' will never be drawn to the endless belt 5 to cause misalignment, and the delivery operation can be performed stably with a constant pitch kept. Changeover of these operations is practicable even with the belt 5 running, which does not require drive control of the belt 5, and when it retracts, no solids are in contact, so that the wear of the belt 5 is less.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a stacking and feeding mechanism for paper sheets, and in particular, to a stacking mechanism using an endless belt, it is possible to stably stack and feed paper sheets. The present invention relates to a deposition mechanism suitable for.

[Conventional technology]

The conventional paper sheet stacking device is Utility Model 6O-IQ9171.
It is dangerous to feed paper sheets into the storage section using a pair of rollers located at the end of the conveyance path that feed the paper sheets into the storage section, and an endless belt that rotates as the rollers rotate, as described in . There is a mechanism for depositing good paper sheets, which has a structure in which it is dropped and deposited. Further, there is a paper sheet stacking and feeding mechanism which combines a paper sheet stacking mechanism with a feeding means, as described in Japanese Patent Laid-Open No. 59-45745.

[Problem to be solved by the invention]

The conventional sheet stacking mechanism described in Japanese Utility Model Application Laid-Open No. 60-109171 has high performance and a small number of parts.

Therefore, it is very convenient to combine the paper sheet dispensing means and use it in a paper sheet stacking and dispensing mechanism of an automatic cash handling device or the like. FIG. 5 shows a side sectional view of an example of a sheet stacking and feeding mechanism using a conventional stacking mechanism. However, in this type of mechanism, when switching from the sheet stacking operation to the feeding operation, it is necessary to raise the sheet group 1' in the storage section 2 by a moving mechanism and bring it into contact with the pickup roller 51, which is the feeding means. be. The rear end of the sheet group 1 that rises during this switching pushes up the endless belt 5, so the increased pressing force between the endless belt 5 and the sheet group 1 at this time causes the sheet group 1' to move as shown by the broken line in FIG. There is a problem that the pickup is pulled into the pickup and becomes an obstacle to the next feeding operation if the alignment position is uneven.To solve this problem, a pickup as described in the above-mentioned prior art Japanese Patent Application Laid-Open No. 59-45745 is proposed. A paper sheet stacking and feeding mechanism is provided with a contact means that can change the rotational position of the endless belt as the roller moves, and has a structure in which the rotational position of the endless belt is retracted by the contact means when paper sheets are fed out. be. However, this mechanism has the problem that since the fixing member comes into contact with the endless belt, the endless belt must have wear resistance to withstand this, making it difficult to extend the service life. The object of the present invention is to solve the above-mentioned drawbacks and realize a stacking and dispensing mechanism capable of stably stacking and dispensing paper sheets.

[Defined means to solve problems]

The above object is to provide a means for moving the guide means that holds the endless belt and determines the protrusion position, and to move the position of the pressing row 2 when switching between the stacking operation and the feeding operation of paper sheets. This can be achieved by creating a structure in which the protruding position of the endless belt is moved.

[Effect]

When changing the sheet stacking operation to the feeding operation, the protruding position of the endless belt can be retracted by moving the position of the guide means, so that the rear ends of the sheets are not drawn into the endless belt and are aligned. Keep it in good condition and leave it as it is
Switching from operation to feeding operation is possible υ, and feeding operation is stabilized.

(9) In the present invention, since the endless belt can be retracted without contacting the fixing member, unnecessary wear of the endless belt does not occur, and it is possible to switch from the stacking operation to the feeding operation without stopping the rotation of the endless belt. Therefore, there is no need to control the drive of the endless belt. [Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

The same parts are given the same reference numerals throughout the figures.

First, the configuration of this embodiment will be described with reference to FIGS. 1, 2, and 5. In FIG. 1 showing a side sectional view of this embodiment, the paper sheets 1 sent in the direction of arrow P from the previous stage during the stacking operation are handled by a leading edge guide 1° 21, a trailing edge guide 22, and a carrier 23. A feed roller 5 is rotated by a power source K (not shown) to feed the storage portion 2, a counter roller 24 is driven opposite to the roller 5, and an endless belt 5 has elasticity and rotates as the feed roller 50 rotates. are arranged.

The endless belt 5 is pressed against the belt roller 7 by the pressure rollers 6a and 6b, and is held so as to protrude above the storage section 2 as shown in the figure. As shown, they are arranged on both outer sides and near the center of the feed roller 3. The shaft 8 to which the belt roller 7 is fixed, and the shaft 9 to which the feed roller 3 is fixed are as follows.
It is connected by a pair of gears 10 and 11, and an endless belt 5
is configured to rotate at a constant speed ratio with respect to the rotation of the feed roller 6. The opposing roller 4 is supported by the shaft 8 via a bearing 12, and is driven separately from the belt roller 7 by a pair of opposing feed rollers 5.

On the other hand, the chiaria 23 holding the stacked paper leaf group 1
is movably supported on the rail 24, and the carrier 2
By driving the belt 25, which is fixed to the belt 5, by a drive source (not shown), it can be moved up and down in accordance with the amount of the sheet group 1' and the operating conditions of the stacking and feeding of the apparatus.

On the other hand, the aforementioned pressing rollers 6α, 6h are fixed to a holder 27 supported by the shaft 8 via a bearing 26, and a link 29 is engaged with a pin 28 provided at one end of the holder 27. When the link 29 is pushed and pulled in the direction of the arrow S by a drive source M (not shown), the suppression rollers 6G, 64 are fixedly rotated around the shaft 8, and accordingly, the protruding portion of the endless belt 5 is moved to the first position. It can be moved to the position shown in the figure and FIG. 5 as appropriate.

Further, above the storage section 2, a group of paper sheets 1 is provided during the feeding operation.
A pickup roller 31 having a rubber portion on a portion of the sheet group 1' to feed out the sheets at regular intervals, and a feed roller 3 arranged in pairs to separate and feed out the sheet group 1' one by one.
2 and a gate roller 55 are provided.

In the high-quality paper sheet stacking and feeding device configured as described above,
First, during the stacking operation, as shown in FIG.
At the same time, the link 29 is pulled to move the protrusion of the endless belt 5 toward the storage section 2. The paper sheet 1 is held between a rotating feed roller 3 and an opposing roller 4, and is pushed by an endless belt 5, which also rotates, and is sent to the storage section 2 while being deformed into a corrugated plate shape as shown in 1 in FIG. 9 is thrown in. By deforming the paper sheet 1 into a corrugated plate shape, even if there are folds, wrinkles, etc., the paper sheet 1 has high rigidity in the feeding direction and is stable without bending in the middle, so that it is stable in the order of Fig. 4 (α) → (hl). , the diameter of the hole that has come loose from the grip between the feed roller 3 and the opposing roller 4,
Furthermore, the endless belt 5 is fed until the leading end contacts the leading edge guide 21. At that time, the endless belt 5 is moved by the frictional force generated by the contact pressure with the sheet 1 as shown in FIG. 4(C).
As shown in Figure 4 (di), the side of the arrow α becomes the tension side, and the side of the arrow becomes the slack side, and the sheet rides on the rear end of the sheet 1, and as shown in Fig. 4 (di), the sheet 1 is knocked down onto the sheet group 1. As a result, the paper sheets 111- are stacked in good alignment on the paper sheet group 1', and the stacking operation progresses in a stable manner one after another without the subsequently fed filter paper sheets 1 colliding with each other.

Next, during the feeding operation, the link 29 is pushed to rotate the pressure rollers 6a and 6b, and the endless belt 5 is moved to the fifth position.
As shown in the figure, the sheet group 1' is retracted from above, and the carrier 23 is moved upward to bring the sheet group 1 into pressure contact with the pickup roller 51. Next, the pickup roller 51,
When the feed roller 32 is rotated to the right in the figure by a power source N (not shown), the sheet group 1' is sent out at regular intervals, and the feed roller 52 rotates like the pickup roller 51 and the gate roller 55 does not rotate. The sheets are separated one by one and fed to the next stage.

As described above, according to this embodiment, the endless belt 5
The endless belt 5 can be stacked stably and well-aligned, and when switching between the stacking operation and the feeding operation, the endless belt 5 is
Since the retracting movement can be performed by a movement of 6 hours, the endless belt 5 is not pushed up when the carrier 25 rises, and the sheet group 1 is not drawn into the endless belt 5 and becomes misaligned. is maintained and stable, allowing for the next operation. In addition, the operation can be switched even while the endless belt 5 is rotating, so there is no need to control the drive of the endless belt 5, and since the endless belt 5 does not come into contact with fixed objects when it is retracted, there is no wear on the endless belt 5. .

Furthermore, since the endless belt 5 moves immediately with the rotational movement of the pressure rollers 6α, 6h, the endless belt 5 can be moved simultaneously with the movement of the carrier 25, and the switching time does not increase.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to switch between the stacking operation and the dispensing operation while maintaining the aligned state of the stored paper sheets, which has the effect of making the dispensing operation of the paper sheets more stable. Since it does not come into contact with fixed objects when it is retracted, unnecessary wear of the endless belt can be prevented.

Secondly, it is possible to change the operating state (accumulation and feeding) while rotating the endless belt, and there is no need to control the drive of the endless belt.
