Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a paper sheet stacking and dispensing mechanism, and more particularly to a paper sheet handling device suitable for automatic cash handling devices of busy banks and the like. .

[Background of the invention]

Conventionally, as described in Japanese Patent Application No. 58-48715, etc., a device has been used to temporarily store paper products accumulated in the upper part of the device in a storage box below and then feed it out again.
There is a mechanism for storing the accumulated paper sheets by tilting the push plate on which the stacked paper sheets are placed and sliding them down into the storage box below.

On the other hand, in order to separate the stored paper sheets one by one and feed them stably at regular intervals, it is necessary to
In particular, it is necessary to minimize misalignment of the storage position in the feeding direction, disorder of alignment, etc.

In the above-mentioned mechanisms, no consideration is given to means for correcting the alignment during storage when the stacked paper sheets are slid off the push plate and stored.

In addition, the mechanism for feeding out paper sheets stored in this type of device is
At the bottom of the storage box, a pickup roller that comes into contact with the stored paper sheets is used to feed out the paper sheets one by one. The rollers are interlocked and normally rotate freely in the standby state, and paper sheets stored in contact with the pickup roller tend to move back and forth in the feeding direction, and may be misaligned due to external forces such as vibrations. The sex is great.

[Purpose of the invention]

An object of the present invention is to address the above-mentioned problems and to provide a paper sheet handling device, such as an automatic cash handling device installed in a bank, which needs to distinguish between paper sheets that have been accumulated once and sheets that are to be accumulated next. An object of the present invention is to provide a paper sheet handling device capable of storing paper sheets while minimizing disturbances in alignment and positional deviations in order to stably feed paper sheets one by one at regular intervals.

[Summary of the invention]

To achieve the above purpose, in order to distinguish between the paper products that were piled up first and the paper products that were piled up next, the push plate supporting the paper sheets that had been piled up was tilted so that the paper sheets that were piled up first were stacked first. When paper sheets slide down to the bottom of the push plate and are stored, in order to feed out the paper sheets stably next time, it is necessary to minimize the disturbance of alignment and positional shift during storage. For this purpose, the alignment of the stored paper sheets is corrected by vibrating the push plate, and the rotation of the pickup roller that comes into contact with the stored paper sheets is regulated to prevent misalignment.

That is, the present invention comprises a paper sheet transport mechanism that is composed of a belt and a pulley and that transports paper sheets to the upper side of the apparatus, and a push plate that is biased from below by a spring or the like at one end of the belt of the paper sheet transport mechanism. It has a stacking mechanism that sequentially stacks conveyed paper sheets, tilts the push plate, and slides the stacked paper sheets into a storage box provided on the lower side to sequentially store them, and a push plate. Feeds provided at the front in the transport direction are provided by pick-up rollers arranged so as to be able to contact each paper sheet from above the paper sheets stacked above and from below the paper sheets stored in the storage box. In a paper sheet stacking/feeding device that consists of a paper sheet feeding mechanism that feeds paper sheets to a roller, separates them one by one, and feeds them out, the paper sheet stacking/feeding device sequentially stacks/stores paper sheets and feeds them out. A push plate vibrating mechanism is installed that vibrates the push plate during the operation of tilting the push plate and pulling out the paper sheets that have accumulated on the upper side while sliding them into the storage box to store the paper sheets in a well-aligned manner. It is characterized by

In addition, the pickup roller that can come into contact with the paper sheets stored in the storage box is prevented from rotating in the direction opposite to the paper sheet feeding direction, so that the storage position of the paper sheets that are stored in contact with the KL and pink up rollers is adjusted. The present invention is characterized in that it is provided with a pickup roller direction rotation mechanism that prevents the rotation of the pickup roller.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described in detail using the drawings.

FIG. 1 is a side view of a sheet stacking and feeding device which is an embodiment of the present invention.

The push plate 20 is rotatably attached to a shaft 22 that is rotatably supported by a carrier (A) 21.

When stacking the banknotes which are transported by the conveyor belt 1.2 to the device in the direction of the arrow A, the separator 20 is held by a locking lever 24 together with a horizontal pressure shaft 22 and a latch 23 fixed thereto. On the other hand, carrier (A)
21 is connected to a carrier (B) 25 via a spring 26, and is slidable up and down using a rail 9 as a guide by a bearing 7.8, and applies appropriate pressure to the conveyor belt 1, that is, the stacked banknotes 53a. .

Further, the carrier (B) 25 is connected to the bearing 13 by a timing belt (not shown) and a motor that drives the timing belt.
It can be slid up and down using the rail 9 as a guide via 14.

When the cantilever 28 is pushed up in the direction of arrow J, the lock lever 24 rotates in the direction of the arrow and the latch 23 is released.
The push plate 20 falls down in the direction of arrow G due to its own weight, but as shown in FIG.
It is held tilted at a small angle from the vertical direction by a spring 15 fixed to. FIG. 2 is a diagram for explaining the operations of the press plate vibration mechanism and the pickup roller direction rotation mechanism. The carrier (A) 21 is provided with an electromagnetic solenoid 16 at a position where the push plate 20 held in the state shown in FIG.
The push plate 20 is configured to swing in the direction of arrow M due to OF'F.

On the other hand, a pickup roller 36 provided below the storage box s4 is supported by a one-way clutch 17 so as to be rotatable only in the direction of arrow B.

An example of the operation of an embodiment based on the present invention will be described below. The carrier (B) 25 is lowered by a motor (not shown). A part of the carrier (B) 25 (not shown) is a carrier (
A) 21 K contact, carrier (A) 21 and carrier (
B) 25 begins to descend all at once.

Up until now, the spring 26 has contracted and the carrier (A)
21 is stopped. After that, the cantilever 28 continues to descend, and the cantilever 28 is moved to the bottom plate 12 or the already stored banknotes 36.
is pushed by the upper surface of the press plate 20 and rotates in the direction of arrow J as shown by the dashed line in FIG. At this time, the rotation of the shaft 22 is determined by a sensor (not shown), and the motor (not shown) is stopped to stop the lowering of the carrier (A) 21 and the carrier (B) 25. Next, when the motor is reversed and the carrier (B) 25 is raised, since the carrier (A) 21 is connected to the carrier (B) 25 via the spring 26, the carrier (B)
25 rises. The push plate 20 has rollers 35
The banknotes are not moved along the bottom plate 12 or the upper surface of the stored banknotes 36, but fall down further, passing through the state shown by the dashed line in FIG. 2, and then reaching the state shown in FIG. 2, that is, the vertical state and a slightly tilted state. At the same time, the stacked banknotes ssb slides down on the push plate 20 so that its tip overflows the guide 11. At this time,
Since the pickup roller 6b is rotated only in the direction of arrow B by the one-way clutch 17, it has an appropriate resistance force against the direction in which the stacked banknotes 53b or the stored banknotes 3b are dragged by the pusher plate 20 and moved toward the pusher plate 20 side. and prevents misalignment when stored. On the other hand, the pickup roller 3b is freely rotatable in the direction of feeding the stored banknotes 56 to the feed roller 4b and the gut roller 5b, that is, in the direction of arrow B. By rotating the cam 6 by a drive source (not shown), the pickup roller 3b is rotated. It rotates at intervals and can feed out the stored banknotes 36 one by one at regular intervals. When the electromagnetic solenoid 16 is turned on and off as appropriate in the state shown in FIG. can be arranged.

After that, the carrier (A) 21 and the carrier (B) 25 are further raised until the carrier (A) 21 reaches the fixed position where the banknotes are accumulated (then the carrier (A) 21 is moved to a stopper (not shown) provided above the banknotes). 3 makes contact and stops. Figure 3 shows the push plate carriers (A) and (B) mounted on the banknote stacking and dispensing device.
) is a vertical cross-sectional view of. The carrier (B) 25 continues to rise further, and the cam 40 provided on the carrier (B) 25 shown in FIG. 3 lifts the lever 41 on the carrier (A) 21. The lever 41 is fixed to a gear 58, and the gear 3B is meshed with a gear 39 fixed to the shaft 22, so when the lever 41 is lifted, the shaft 22 rotates, lifting the push plate 20 in the direction of arrow H, and locking the lever. 2
4, the shaft 22 and the press plate fixed thereto are held and locked in a horizontal state through the latch 23, and the series of operations is completed in a state in which banknotes conveyed by the new busy conveyor belt 1.2 can be stacked.

According to this embodiment, by vibrating the push plate 20 and rotating the pickup roller 3b only in the feeding direction, the stacked banknotes 5 are stored in the storage box 34 at the bottom of the push plate 20.
The banknotes 36 to be stored separately from the banknotes 51 can be stored with less misalignment and disordered alignment.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, when the banknotes stored in the storage box are stably fed out, it is possible to reduce the displacement of the storage position and the disturbance in the alignment of the banknotes stored in the storage box. This function prevents defective bills, that is, abnormal intervals between bills being fed out, and feeding out a large number of overlapping bills, and allows bills to be fed out one by one at regular intervals, making it possible to reliably count the bills being fed out and prevent bill jams during the conveyance path. This has the effect that it is possible to prevent such problems from occurring and to ensure stable operation of the device.
