Abstract

PURPOSE:To release biting into a paper sheet easily by providing a separation feeding means and a separation resistant means as a separation take-out means of paper sheet and driving said means through a driving mechanism in the counter feeding direction of paper sheet when required. CONSTITUTION:Upon rotation of a feed roller 20, a pickup roller 34 will rotate intermittently in synchronization with the feed roller 20 through a cam 31. Consequently, the uppermost paper sheet B is fed to the separating section comprising the feed roller 20 and a gate roller 25. Upon simultaneous biting of plural paper sheets B at the separating section, a pushboard 62 is first lowered by a drive motor 42 until the switch section 82 interlocked with a lever 81 for detecting the existence of paper sheet is turned off. Then an arm 29 is rotated to retract such as the roller 34 upward thereafter, the feed roller 20 is rotated reversely to rotate the gate roller 25 in the counter feeding direction, resulting in release of biting into the paper sheet B.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a paper sheet handling device that accumulates conveyed paper sheets in a storage section and separates and takes out the sheets one by one from the storage section as necessary. be.

[Background of the invention]

Conventional paper sheet handling devices include, for example, Japanese Patent Application Laid-Open No. 58-2
In the system disclosed in Japanese Patent No. 20043, a vacuum drum is used as a feeding means for feeding out paper sheets accumulated in a storage section, and the paper sheets are adsorbed by vacuum and separated and taken out. This conventional method requires a device to generate a vacuum, which increases the size of the device, and if the paper sheet is bent or torn, the suction operation becomes unstable, making it difficult to take out the paper sheet incorrectly. It is conceivable that the separation and removal performance of paper sheets may be deteriorated.

Moreover, when separating and taking out paper sheets, the paper sheets to be taken out will stop with the paper sheets remaining in the separating section, which will have a negative effect on the next sheet stacking operation.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a paper sheet handling device in which the stacking operation of paper sheets is stabilized.

[Summary of the invention]

A feature of the present invention is that an impeller receiving and guiding means is used as a paper sheet receiving and guiding means, a friction feeding means is used as a separating and feeding means, and a sheet is provided near the feeding means so as to come into contact with the paper sheets. A deformation regulating means is provided to restrict the deformation of the fed filter paper sheets, and a separating and sending means and a separation resistance means are installed to separate and send out the fed paper sheets one by one at regular intervals. Further, the receiving guide means, the feeding means, and the paper sheet deformation regulating means are structured to be able to swing in accordance with the time of stacking the paper sheets and the time of separating and feeding out the paper sheets, respectively. The feeding means and paper sheet deformation regulating means are retracted from the paper sheet surface to enable stacking of paper sheets, and when separating and feeding out the paper sheets, the retracted feeding means and paper sheet deformation regulating means are retracted from the paper sheet surface. The two stacked paper sheet feeding faces are brought into contact with each other, and the swinging is controlled so as to enable separation and feeding of the paper sheets and control of deformation of the paper sheets. Further, the pressing force between the receiving and guiding means and the paper sheet accumulation surface, and the engagement position and pressing force between the feeding means and the paper sheet are controlled.

In these figures, two feed rollers 2o are provided on a shaft 23 rotatably supported by a frame 22, and have a friction member 21 on a part of the circumference thereof. On both sides of the two feed rollers 20, stopper rollers 24 are disposed coaxially with the shaft 23, as shown in FIGS. 2 and 3. The stopper roller 24 is made of a material with a low coefficient of friction, such as metal. The feed roller 20 and the stopper roller 24 each have a groove 20A in the circumferential direction.

It has 24A. A gate roller 25 made of a friction member is inserted into these grooves 20A and 24A.
! 'ii! Being fucked. That is, feed roller 2
0 and gate roller 25. A stopper roller 24 and a gate roller 25 are arranged to overlap each other.

On the other hand, a timing pulley 26 is attached to one end of the shaft 23. This pulley 26 has a timing belt 2
It is multiplied by 7. Although not shown, this belt 27 is connected to, for example, a step motor that can rotate in forward and reverse directions. This motor operates in response to a signal from a paper waste passage sensor (not shown) disposed on the paper waste discharge path side of the feed roller 20. As a result, the rotation of the shaft 23, that is, the feed roller 20 and the stopper roller 24 is controlled. In the portion between the feed rollers 20 and 20 of the shaft 23,
The f\ wheel 28 is fixed. This gear 28 engages with a gear 30 that is rotatably mounted on an arm 29 that is swingably mounted around the shaft 23. On the side of this gear 30,
A cam 31 is attached coaxially with this and rotates together with the gear 30. Further, a free rotation shaft 32 attached to one end of the arm 29 is provided with a rubber roller 33 at a position where it engages with the cam 31, and a separating and feeding means for separating and feeding out paper sheets made of rubber with a high friction coefficient for applying a conveying force to the paper sheets. A pickup roller 34 is fixedly attached thereto. Further, the arm 29 is rotatably provided with a detection lever 81 that detects the presence or absence of filter paper below the pickup roller 34. This detection lever 81 is positioned so that one end side is in contact with the opposite side of the paper, and the other end side is turned on and off by rotation of the detection lever 81.
It is linked with a switch section 82 that performs F. This switch section 81 is turned on when a certain amount of paper waste is accumulated on a push plate 62, which will be described later. When the gear 28 rotates once, the cam 31 contacts the rubber roller 33 by a predetermined rotation angle and rotates the pickup roller 34. That is, cam 3
By the action of J-.

When the shaft 23 rotates, the feed roller 20 and the pink-up roller 34 will be driven synchronously. The pickup roller 34 is in contact with the center portion of the paper sheet B in the longitudinal direction when the paper sheets are separated and fed out.

When the feed roller 20 is rotated, power from the gear 28 fixed to the shaft 23 is transmitted to the cam 31.
, the pickup roller 34 rotates intermittently in synchronization with the feed roller 20. As a result, the top paper B pressed against the pickup roller 34
is sent to a separating section constituted by a foot roller 20 and a gate roller 25. At this time, if the separation and take-out operation ends with a plurality of sheets of paper B being simultaneously fed into the separating section due to the frictional force caused by the rotation of the pickup roller 34, the paper may be caught between the feed roller 20 and the gate roller 25, The state remains as it was. In this state, the single impeller 54 cannot receive and collect the paper sheets B, so the above-mentioned biting and returning operation of the paper sheet B, that is, the paper held between the feed roller 2o and the gate roller 25, It is necessary to push B back into the storage section. This operation of returning the paper to the paper will be explained with reference to FIGS. 4 and 5. First, by driving the drive motor 42, the push plate 62 is lowered until the switch section 82 interlocked with the sheet presence/absence detection lever 81 is turned off. Next, the arm 29 is rotated by the rotation of the cam 45 shown in FIG.
by rotating the pickup roller 34. Roller 72.
The guide roller 39 and stopper 47 are retracted in the opposite direction.

Next, rotate the feed roller 20 in the opposite direction to that at the time of separation (
When the gate roller 25 is rotated in the opposite direction (reverse rotation), the gate roller 25 is free to rotate in the counter-feeding direction. 25 rotates in the opposite direction. As a result, the jamming of the paper that is caught and held in the separating portion is released. The rotation of the gate roller 25 in FIGS. 4 and 5 was given by the rotational force of the feed roller 2o and the gripping force of the paper in the separation section, but as shown in FIG. gear 2
It goes without saying that the same effect can be obtained even if the gate roller 25 is driven by a gear 25a with a one-way clutch provided on the gate roller shaft 25A by providing a gear 25a with a one-way clutch provided on the gate roller shaft 25A. In addition, as shown in FIG. 7, a DC motor 55 is installed and a gear 55a attached to the DC motor shaft 55A is used to constantly move the gate roller 25 in the counter-feeding direction even when the gate roller 25 is bitten back after being separated and taken out or when being separated and taken out. A similar effect can be obtained by driving.

In addition, although the above-mentioned embodiment describes a structure in which paper scraps are piled up or separated in the horizontal direction, the present invention can also be applied to a case where paper scraps are in an upright position.

In each of the embodiments described above, a case has been described in which paper sheets are handled as paper sheets, but it goes without saying that similar effects can be obtained with other paper sheets such as slips.

〔Effect of the invention〕

According to the present invention, when switching from the separated state to the integrated state,
Since it is possible to release paper sheets from being caught in the separating section, stable stacking of paper sheets can be performed.
