Description

[Detailed Description of the Invention] (Industrial field of application) The present invention classifies and counts paper sheets like a paper sheet processing machine, for example, a banknote classification and counting machine, and then stores the banknotes. The present invention relates to a paper sheet storage device used for.

(Prior Art) Conventionally, there is a technology as disclosed in Japanese Utility Model Laid-Open No. 60-126446, for example, as a bill storage device in the above-described paper sheet processing machine.

The above-mentioned conventional technology is detachable from the main body of the banknote handling machine, has an opening at the top, has a receiving plate inside, and a storage box for storing processed paper sheets such as sorting and counting, An elevating body that engages with a protruding portion of a receiving plate provided in the main body of the processing machine and protrudes from the storage box and displaces the receiving plate in accordance with the amount of paper sheets stored, By driving, the receiving plate is moved up and down according to the amount of paper sheets in the storage box.

(Problems to be solved by the invention) However, in the above-described conventional technique, it is necessary to drive the elevating body that displaces the receiving plate according to the amount of paper sheets stored in the storage box. The amount of paper sheets or the amount of paper sheets to be stored is detected, and the receiving plate is displaced according to the result. Therefore, a large number of paper sheet detecting means are required, and a driving means for driving the elevating body is required. Since it is necessary, there is a problem that the device becomes complicated and the device itself becomes expensive.

On the other hand, separately from this, the receiving plate of the storage box is always urged by a spring or the like toward the opening for storing paper sheets, and the stored paper sheets are stored in the storage box against the above spring bias. There are things that were designed to be pushed in.

According to this configuration, the structure of the device itself is simplified and it is possible to provide the device at low cost, but when the paper sheets are stored in the storage box, the receiving plate does not descend due to its own weight. First, it is necessary to strengthen the spring that biases the receiving plate toward the opening.

Therefore, with the above configuration, when the paper sheets in the storage box are removed, the receiving plate vigorously rises due to the urging force of the spring, so when removing the paper sheets, direct the receiving plate toward the bottom of the storage box. It is necessary to pull it out while it is being held down, which results in poor workability.

In view of this, the present invention has been made for the purpose of providing a paper sheet storage device capable of improving the workability at the time of removing paper sheets with a simple configuration.

(Means for Solving the Problem) In order to solve the problems of the above-described conventional technology, the present invention provides a paper sheet that is pushed by a paper sheet pushing member from the opening of the paper sheet storage section in the storage section. In a paper sheet storage device for receiving a paper sheet in a pressed state by a backup body urged toward the opening, a backup body for urging the backup body toward the opening Urging means, a pair of rollers provided so as to be movable integrally with the backup body, and a contact surface portion provided in the paper sheet storage section for maintaining a contact state with each of the pair of rollers when the backup body moves. A pressing means that presses the pair of rollers toward the contact surface portion, and the rollers can rotate when the backup body moves in the direction of the opening, and the roller is opposite to the opening. And a one-way clutch that disables rotation of the roller when moving in the direction.

(Operation) When the paper sheet is stored in the paper sheet storage unit, the backup body is prevented from descending due to frictional contact between the roller and the contact surface portion. At the time of removing the paper sheets, the roller rotates and the backup body moves toward the opening by the urging means.

Between both or one of the rollers 50, 50 and its shaft 53, 53, the rollers 50, 50 are free when the backup body 41 moves in the ascending direction, and the rollers 50, 50 do not rotate when the backup body 41 descends. One-way clutches 59, 59 for restraining are interposed. As the one-way clutches 59, 59, those having a structure in which the rotation of the rollers 50, 50 is restrained by a wedge action by a combination of a ball and an inclined surface are used as is known.

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

When the banknotes P are loaded into the hopper 4 of the machine body 1 and started, the banknotes are picked up one by one by the not-shown pick-up means, and the banknotes that are discriminable to be taken in by the discriminating unit 6 are conveyed through the conveyance path 7 and are classified by type. All of the banknotes fed into the temporary storage units 3a, 3a, 3a provided above the banknote storage devices 3, 3, 3 and then loaded in the hopper 4 are temporarily stored in the respective temporary storage units. , When the storage button etc. is operated,
First, the bottom plate of the temporary holding unit 3a is released by a drive mechanism (not shown), and the temporarily holding banknotes enter the temporary storage unit 11 of the storage unit.

In the temporary storage section 11, since the pushing members 23 and 24 are both in the upright state and located outside the machine casing 10 as shown in FIGS. 5 and 10 (A), the upper portion of the machine casing 10 is opened. The partition members 13, 13 ... Are projected into the temporary storage portion 11 as shown in FIGS. 1 and 4. Therefore, the banknotes that have entered the temporary storage section 11 are temporarily received with the lower surfaces on both sides in the longitudinal direction thereof being placed on the partition members 13, 13.

After that, when all the banknotes in the temporary storage unit 3a are stored in the temporary storage unit 11 due to the lapse of a predetermined time, the motor M ₁ is activated, the crank plate 19 is rotated, and the left and right crank levers 21 and 21 are moved together. Pull to swing the arms 22,22,
Rotate in directions opposite to each other (direction of arrow in FIG. 1). Based on this, the shafts 15 and 15 rotate in opposite directions through the bevel gears 18 and 16, respectively, and the partition members 13 and 1 fixed to the upper ends thereof.
3 rotate as shown by the arrow in FIG. 1 to retract from the temporary storage portion 11 to the outside of the machine frame 10 (FIG. 10 (B)).

On the other hand, the motor M _{2 is} also started, the crank plate 32 rotates, the crank lever 30 is pulled, and the arm 28,
28 rotate in opposite directions, and long push members 23, 23
.. rotate in the fall direction, and the rollers 27, 27 at the tip end push downward near the center of the banknote in the width direction.

The short pushing member 24, which is interlocked with one long pushing member 23 on one side via the link mechanism 25, tilts and turns slightly later than the long pushing member 23 through each lever 35, 36, 38 of the link mechanism 25 ( FIG. 10 (D)), the pressing portion 33 at the tip hits the upper surfaces of both side edges of the banknote in the longitudinal direction to press the banknote, and the banknote is flat as a whole even when the banknote is fluffyly accumulated like a circulating banknote. It is pressed so that
It is pushed inside. At this time, in the storage space 12, the bill is received on the backup body 41, the backup body 41 resists the tensile force of the spring 42, which is a biasing means, and the rollers 50, 50 come into contact with each other according to the storage amount of the bill. It slides and descends against the frictional force with the surface portions 56, 56.

When the pushing is completed, the pushing members 23, 23 ... Rotate in the standing direction, while the partition members 13, 13 ... Pivot in the projecting direction to advance to the upper surface of the stored banknotes, and on the backup body 41. The accumulated banknotes are stored in a state of being sandwiched between the backup body 41, which is biased upward by the spring 42, and the lower surface of the partition member 13, 13 ...

The banknotes thus fed into the temporary storage section 11 are then stored in the storage space section 12 in the same manner as described above, and the storage space section 12 is stored.
As a compressed state, a large number of banknotes can be stored therein.

When the storage space 12 is full, the machine body 1 to the machine frame 2
... and the partition members 13, 13 ... And the pressing members 23, 23 ... With each retracted to the outside of the machine frame 10, a door (not shown) is opened, and a required number of banknotes are grasped and taken out from the upper part.

In this way, when the appropriate amount of banknotes in the upper position is taken out, the backup body 41 is biased by the spring 42 and the roller 5
When the one-way clutches 59, 59 of 0, 50 are released, the rollers 50, 50 rotate and rise. However, the above spring 42 is a weak spring as long as it has a force enough to raise the backup body 41, and therefore the backup body 41 does not rise sharply and rises gently by the amount of the bills taken out, The remaining bills are supported stably, and the piled state of bills is not disturbed.

In the illustrated embodiment, the case of handling banknotes has been described, but it is applicable to paper sheets other than banknotes, and the specific configuration of each part is not limited to the illustrated embodiment.

[Effect of device]

As described above, according to the present invention, the roller does not rotate due to the one-way clutch when the paper is stored in the paper storage unit, and the friction force between the roller and the contact surface prevents the backup body from descending. Therefore, the urging means for urging the backup body toward the opening may be weak, and the problem that the backup body suddenly rises when the paper sheets are removed does not occur. In addition, since the backup body can be configured without using any driving means such as a motor, it is not necessary to provide a detecting means, a driving force transmission system, etc., which accompany the backup means, and the device configuration is simple, small and inexpensive. Therefore, there are various effects such as a storage device having excellent operability and the like.
