Abstract

PURPOSE:To make paper sheets possible to be accurately separated and delivered without being affected by an ambient temperature change, by controlling the driving speed of a separate roller part having a driving source separate from that of a conveying part, on the basis of detected results of conveying speed in the conveying part. CONSTITUTION:Operation of a separate roller part speed control mechanism compares a standard conveying speed code being stored in a read-only memory 35 with a speed code corresponding to the existing speed to be detected by a conveying speed detector 34 by a separate roller speed compensation control part 36, and transmits a step motor control signal corresponding to the difference to a separate roller speed control part 37. Next, this separate roller speed control part 37 converts a speed compensation code into a speed control pulse value of a step motor, transmitting it to a separate roller driving part 25, and it controls speed of the step motor. Thus, accurate separation and delivery of paper sheets are made performable with simple constitution, without being affected by any ambient temperature change.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a paper sheet handling device, and in particular, when paper sheets are sent to a conveyance path by a separation roller, the conveyance speed of the paper sheets in the conveyance path is controlled. The present invention relates to a paper sheet handling device that enables reliable separation and delivery of paper sheets with a simple configuration by controlling the paper sheet delivery speed of the separating roller according to the above.

[Conventional technology]

For example, in conventional banknote handling devices that have a separating mechanism for separating paper sheets on the side of the stacking mechanism that stacks paper sheets, the leading edge of the next banknote gets caught in the first separation roller when separation is completed. If the stacking continues, problems such as multiple separation or separation jams will occur during the next separation. Therefore, after separation is completed, the separation roller is reversed to remove the next and highest banknotes. At the same time, a process is performed to return the bit of the tip of the bill that has been fed out to a certain extent to its normal position.

For this reason, in conventional devices, for example,
As described in Japanese Patent No. 72590, it is known that the drive source for the separation roller and the drive source for the conveying section are provided separately, and a forward/reverse switching clutch is provided on the drive side of the one-separation roller.

[Problem that the invention seeks to solve]

However, in the above-mentioned recirculation banknote handling device equipped with a separation mechanism for separating paper sheets on the stacking mechanism side,
If a forward/reverse switching clutch is provided, there is a problem in that the mechanism becomes more electrified.

Also, the separation roller drive! +If the IJ source and the drive source for the conveyance section are provided separately, it is necessary to synchronize the conveyance speed of the conveyance section and the bill delivery speed from the separation roller, but this has the following problems. .

In other words, when the drive source for the separation roller and the drive source for the conveyance section are provided separately, a motor such as a step motor, which can easily control the rotation, is usually used as the primary drive source for the separation roller. A common AC motor is used as the drive source. However, the rotational speed of the AC motor fluctuates due to the frictional load on the conveyance system caused by changes in the surrounding temperature, so the conveyance speed cannot be synchronized with the separation roller system, which is driven at a constant speed, and the rotational speed between the separation roller and the conveyance section cannot be synchronized. However, problems such as buckling, jamming, and skewing of banknotes occur.

The purpose of the present invention is to solve the above-mentioned problems in conventional paper sheet handling devices, and to reliably separate and send one sheet of paper with a simple configuration without being affected by changes in ambient temperature.
(Our objective is to provide a paper sheet handling device.

[Effect]

In the paper sheet handling device according to the present invention, the drive speed of the separation roller section, which has a drive source provided separately from the drive source of the transport section, is controlled based on the detection result of the interleaving speed of the transport section. This eliminates the speed difference between the conveyance section and the separation roller section.
