Abstract

PURPOSE:To dispense with a system to control a pressing plate pressing paper sheets and simplify a paper sheet storage section by reversely rotating separating rollers while the pressing plate is depressed when a protruded paper sheet s detected by a sensor, and re-storing the protruded paper sheet. CONSTITUTION:When a protruded paper sheet 10 from a paper sheet storage section is detected by a sensor 2, separating rollers 3, 4 are reversely rotated to return the protruded paper sheet 10 to the storage section. The reverse rotation of the separating rollers 3, 4 is stopped by the information of the protrusion detecting sensor 2 when the protruded paper sheet 10 is returned to the storage section.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a paper sheet separation device, and particularly to a paper sheet separation device, and particularly to a paper sheet separation device.
Install the paper sheet separation device that is most suitable for dl.

[Prior Art] When a conventional device of this type detects a sheet protruding from the sheet storage section, the pressing plate that is pressing the surface of the sheet is released from the pressing plate by some kind of drive mechanism, and the separation roller By rotating the paper a predetermined amount in the opposite direction, the paper sheet is bitten back into place. However, in the above-mentioned conventional technology, when a heading is detected on a sheet of paper, the pressure of the push plate pressing on the surface of the sheet is released, the separation roller is reversely rotated by a predetermined amount, and the sheet is separated. It is used for biting back. In this technology, when the cash cassette and the banknote separation/conveyance path are removable, such as in a banknote payment device, a drive mechanism is also required within the cash cassette, making it difficult to transmit the driving force. Furthermore, since the amount of return is not managed, problems may occur due to too much return or not enough return.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the need for a complicated drive mechanism and, moreover, to carry out the return of paper sheets in a manner that prevents problems from occurring when the paper sheets set in a paper sheet storage section are separated.

[Means for solving the problem] In order to achieve the above object, a sensor is provided to detect the heading of the paper sheet, and the amount of reverse rotation of the separation roller is controlled by light and dark information from the sensor. . This eliminates the need to release the pressure of the push plate that is pushing the surface of the sheet. In other words, since the separation roller is not rotated in the opposite direction more than the necessary amount, even banknotes that are still being pressed by the push plate can be returned to the storage unit without disrupting the set state of the paper sheets.

[Operation] When a sensor detects a sheet protruding from the sheet storage section, the separation roller is rotated in the opposite direction to return the protruding sheet to the storage section. At this time, the amount by which the separation roller is rotated in the opposite direction depends on the information from the overflow detection sensor, and the rotation is stopped when the overflowing sheet returns to the storage section. In this way, if the separation roller is rotated in the opposite direction without releasing the pressure from the press plate that is pushing the paper sheets, not only the protruding paper sheets but also the second and subsequent bills will try to move due to the frictional force between the paper sheets. This can be solved by providing a plate serving as a stopper in that direction. [Embodiment] An embodiment of the present invention will be explained with reference to FIGS. 1, 2, 3, 4, and 5.

FIG. 1 is a schematic diagram of a banknote payment device according to an embodiment of the present invention.The banknote payment device can be roughly divided into: 1 a cash cassette, 2 a sensor for detecting the heading of a banknote, and 3 a pickup for a banknote. 4 is a separation roller that conveys banknotes, 5 is a separation roller that separates banknotes one by one, 6 is a roller that clamps the banknotes and sends them to a conveyance path, 7 is a conveyance path, and 8 is a separation roller that conveys the conveyed banknotes. It consists of a payment mechanism section that is stacked and delivered to customers.

FIG. 2 is a side view of the banknote separation mechanism according to the embodiment of the present invention, in which 9 is a push plate that presses the banknote surface, 10 is the first banknote, and 11
12 is a plate for suppressing the disturbance of the set banknotes, 13 is a spring that applies a predetermined pressure to the banknotes, and 14 is a slide for moving the push plate 9 by the spring 13. , 1δ is a sliding shaft, and 16 is a front plate.

FIG. 3 is a schematic side view of the bill separating mechanism during the biting and returning operation. FIG. 4 is a schematic diagram of the bill separating mechanism after the biting and returning operation. FIG. 5 is a flowchart of the biting and returning operation.

Next, as shown in FIG. 2 illustrating the operation of this embodiment, the set banknotes 10.11 are sandwiched between the roller 3 and the push plate 9. In other words, the first banknote 10
is always pressed by the push plate 9 and pressed against the roller 3. Normally, when separating banknotes, rollers 3 and 4 rotate in the direction of the arrow, and the banknotes are separated. When the separating operation is completed, as shown in Figure 3, if the tip of the first banknote 10 exceeds the roller δ, a problem will occur during the next transaction or when pulling out the cash cassette, so the protruding banknote must be pulled back. There is a need. In such a case, the 51st! I
As shown in the flowchart, the rollers 3 and 4 are rotated in the direction of the arrow in FIG. 3 until the bill protrusion sensor 2 turns on, and the bill is pulled back. However, at this time, not only the first banknote 10 but also the second and subsequent banknotes 11 rise due to the frictional force between the banknotes, but because they stop against the plate 12, the set banknotes are not disturbed.

As shown in FIG. 4, since the rotation of the rollers 3.4 is stopped when the sensor 2 turns on, the leading banknote does not rise too much and jam in the banknote storage section.

[Effects of the Invention] The present invention does not require a mechanism to control the push plate that pushes the banknotes, so the banknote storage section can be simplified, and even in a device where the banknote storage section can be attached and removed, it is possible to return the banknotes appropriately. Can be easily adopted□.

[Claims] 1. A spring that applies a predetermined pressure to a push plate that presses the surface of the paper sheet, a sliding part that slides the push plate, a sensor that detects the protrusion of paper sheets from the paper sheet storage section, and a separation that feeds out the paper sheets. A paper sheet separation device consisting of rollers is characterized in that when a sensor detects that a sheet has protruded, the separation roller is rotated in the opposite direction while pressure is still applied to the push plate to re-storage the protruding sheet.
