Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a paper sheet storage and feeding device, and in particular to a paper sheet storage and feeding device that receives paper sheets from an upper opening and stores them in a stacked state. The present invention also relates to a paper sheet storage/feeding device which feeds paper sheets by a feeding means from a feeding port provided at the bottom when necessary, and which is provided in the form of a cassette that is detachable from the machine body.

(Prior Art) In the above-described paper sheet storage device, paper sheets are conventionally stacked and stored on the lower feeding means, so that the uppermost and upper surfaces of the paper sheets stacked here are There is a space between the opening and the opening, and when storing paper sheets, the paper sheets freely fall through this space and are deposited on the feeding means.

In the above device, the paper sheets can be fed into the opening in a manner in which the paper sheets are sequentially fed one by one, or the paper sheets are temporarily held and accumulated above the upper opening. However, the paper sheets are dropped all at once into the upper opening, and in either form, the paper sheets freely fall from the upper opening and are piled up.

(Problem to be solved by the invention) However, in the case of the paper sheet having the above-mentioned storage section, there is an air layer between the paper sheets, which creates a sufficient load on the feeding means such as the feeding roller at the bottom. Particularly as the number of sheets stored decreases, the frictional force with the feeding means ceases to act, resulting in feeding errors (empty feeding).

In addition, as a general feeding means, there is one in which the upper surface of the sheet to be fed is pressed by a pressing member to apply a frictional force to the feeding means.
In the case of the above-mentioned paper sheet storage device, if the pressing member is provided to simply press downward, it will interfere with the paper sheets being fed into the storage section, and a good stacking state will not be obtained. Moreover, since there is a limit to the opening degree of the upper opening of the storage section, it is difficult to feed paper sheets without being damaged by the pressing member.

Furthermore, even if an attempt is made to retract the pressing member to a position where it does not interfere with the paper sheets being fed, it is difficult to retract the pressing member because the sheet storage/feeding device is a cassette type and its size is limited. It was very difficult to find space.

In view of this, the present invention makes it possible to apply a sufficient load to the paper sheets stored in the storage section regardless of the amount of paper sheets stored in the storage section. It is an object of the present invention to provide a paper sheet storage and feeding device that is equipped with a pressing member that can be retracted to a position where it does not interfere with paper sheets being fed into the device, and a drive mechanism for the pressing member.

[Structure of the idea]

(Means for Solving the Problems) In order to achieve the above object, the present invention receives paper sheets from the upper opening of the paper sheet storage section, stores them in a stacked state, and when necessary, the paper sheets are fed through the lower opening. In a paper sheet storage/feeding device which feeds out paper sheets one by one by a feeding means and is provided as a cassette type that is detachable from the machine body, the upper opening is provided to open and close, and when the upper opening is opened, the opening is opened. A shutter stored in a shutter storage section on one side,
a pressing member that is movable between an exit position located directly below the shutter storage section and exited laterally from the paper sheet storage section and a pressing position that presses stacked sheets against a feeding means; The apparatus is characterized by comprising a drive mechanism having a locking mechanism for retracting the pressing member to the exit position when accepting leaves from the upper opening and locking the pressing member in the sheet pressing state when taking out the cassette from the machine body. It is something.

(Function) With the above configuration, when paper sheets are fed into the storage section, the pressing member retreats to the side of the storage section, so that the pushing member does not interfere with the fed paper sheets. Further, when paper sheets are fed out, the pressing member advances into the storage section and presses the paper sheets against the feeding means, so that the frictional force between the paper sheets and the feeding means is maintained. Further, when the cassette is taken out from the machine, the drive mechanism locks the pressing member in the sheet pressing state, thereby preventing the sheets from stacking up and collapsing.

A conveyance path 64 is provided from the bottom of the storage body 5 to the front side for sending out banknotes P paid out from inside each of the cassettes 3 ₁ to 3 ₄ . 65
is a shutter that opens and closes the opening 6.

Next, the operation of the above embodiment will be explained.

The storage body 5 loaded with each cassette ₃₁ to ₃₄ is transferred to the aircraft 1.
When the cassettes ₃₁ to 34 are inserted into the cassettes, the shutters 65 of each of the cassettes 31 _{to 34} are opened by a mechanism not shown, and the openings 6 are placed directly below the temporary storage parts ₄₁ to ₄₄ , respectively. At this time, the pressing member 10 is placed in a retracted position outside the storage portion 9 as shown in FIG.

On the other hand, for example, when a customer places a banknote P in the receiving slot 51 for deposit and enters the receiving operation, the banknote P
The coins are taken in one by one by the group of feeding rollers 52, and while being conveyed through the conveyance path 53, they are identified by the discriminator 54, and according to the recognition results, they are sorted and deposited into the temporary storage units ₄₁ to ₄₄ of each denomination. It will be done.

After the intake from the receiving port 51 is completed, the temporary storage section 4
When a certain amount of banknotes P are stored in the cassettes ₁ to ₄₄ and the movable bottom plates 61, 61 are opened by the take-in signal, the banknotes P are stored all at once from the opening 6 of the cassettes ₃₁ to ₃₄ . Fall into section 9.

The banknotes P that have entered the storage section 9 are transferred to the feed roller 12
The front and rear parts are received by the upper surfaces of the free-rotating roller 15, and the aligning members 38, 38 are swung left and right by an operation mechanism (not shown), so that the width directions of the bills P are aligned.

After a predetermined period of time has elapsed after the acquisition signal was sent, the motor 29 is activated, the pulley 28 rotates counterclockwise, and its pin 27 moves downward. The pressing member 10 starts swinging in the same direction following the pin 27 due to its own weight, and stops when the pressing portion 10A contacts and is supported by the upper surface of the banknote P. When the detected plate 33 rotates 90 degrees, the motor 29 is stopped, but before this happens, the head 27A of the pin 27 escapes from the guide plate 37, so it comes out due to the spring 36 and connects to the groove cam 26. relationship is severed.

Next, when the feed roller 12 is driven in the direction of the arrow by the feeding command, the several bills P from below move forward and their tips fit into the circumferential surface of the gate member 14 (state shown in the third figure). The rear end of the banknote P is the top 15 of the circumferential surface of the freely rotating roller 15.
deviate from A. As a result, when this state is reached, only the lower few banknotes P are supported by the circumference of the hard roller 17 and the feed roller 12, and the higher banknotes P are supported by the free rotation roller 15 and the feed roller 12. It will be done. Therefore, most of the weight of the stored banknotes P is supported by the free rotation roller 15 and the feed roller 12, and is not applied to the hard roller 17.

In this way, when the kicking portion 17A of the kicking roller 17 comes into contact with the lower surface of the lowest banknote P, only one bill is fed out due to the frictional force and sent out through the gate gap L between the feed roller 12 and the gate member 14. , and are sent out of the cassette 3 by the carriers 19 and 20.

The banknotes P sent out from the cassette 3 are extracted from the payout port 50 via the conveyance path 64 in the warehouse 5 and the payout conveyance paths 62 and 63.

When the banknotes P in the cassette 3 are fed out one after another in this way, the pressing member 10 gradually swings downward due to its own weight as the number of banknotes P decreases, thereby constantly pressing the banknotes P against the feeding means 8. , continues to apply the frictional force necessary for feeding (Figures 5 to 6).

When the protrusion 33A of the detection plate 33 interferes with the pin lowering position detection detector 35, the motor 29 rotates in reverse, the pin 27 goes under the guide plate 37 and is pushed out, and its tip touches the groove of the grooved cam member 24. It enters into the cam 26, hits the end of the grooved cam 26 midway, rotates the grooved cam member 24 in the same direction, and swings the pressing member 10 upward to return to the state shown in FIG.

Note that when the storage body 5 is pulled out and the cassette 3 is pulled out while the pressing member 10 is in the pressed state and the pin 27 has come out of the grooved cam 26 as described above, the locking piece 48 of the locking mechanism 39 releases the spring 4.
6 rotates counterclockwise until it hits the stopper 47, the pawl member 43 rotates clockwise due to the spring 42, and its pawl 40 engages with the pawl teeth of the ratchet wheel 25 to restrain the pressing member 10. . Therefore, when the cassette 3 is taken out, the pressing member 10 does not swing erratically, and the bills P are prevented from being scattered.

In the illustrated embodiment, the present invention is applied to a cassette for a banknote circulation processing machine, but it is of course applicable to a dispensing device such as a storage box used as a single unit. The configurations of other parts are also not limited to the illustrated embodiments.

[Effect of idea]

As explained above, according to the present invention, even in a storage and feeding device having a cassette-type paper sheet storage section, the pressing member can be retracted to a position where it does not interfere with the stored paper sheets, and Since the pressing member presses the paper sheet against the feeding means when feeding the leaves, the frictional force between the paper sheet and the feeding means can be maintained. Furthermore, when the cassette is taken out of the machine, the drive mechanism locks the pressing member in the state of pressing the paper sheets, so that various effects such as preventing collapse of the stacked state of the paper sheets are achieved.
