Paper sheet conveyor

Abstract

The invention discloses a paper conveying device. The problem to be solved by the present invention is to provide a preventive maintenance device capable of realizing long-term stable sheet conveyance even when a long-term regular maintenance interval is provided in the sheet conveyance device. The means to solve the problem is that it includes: a stacking plate (2), which stacks banknotes P; a pick-up roller (3), which uses the stacking plate (2) to press banknotes P; a feed roller (4) and a gate roller (5), It separates the banknotes P transported with the rotation of the pick-up roller (3) one by one and transports them to the transport path (11); transport monitoring sensors (10a), (10b), which monitor the banknotes on the transport path (11) The conveying state of the banknote P conveyed on the top, it adjusts the meshing amount of the feeding roller (4) and the gate roller (5) according to the output of the conveying monitoring sensor (10a), (10b), and the paper sheet conveying device is provided with a memory unit ( 18), carrying out statistical processing on the output of the transport monitoring sensors (10a), (10b) and adjusting the meshing amount of the feed roller (4) and the door roller (5), and recording the date and time of adjusting the meshing amount in the memory part ( In 18), when the adjustment frequency calculated from the recorded adjustment date and time exceeds a predetermined frequency, a maintenance request notification is issued from the device.

Description

technical field [0001] The present invention relates to a sheet conveying device for separating and conveying accumulated sheets one by one. Background technique [0002] As a conventional sheet conveying device, for example, there is an automatic banknote handling device. The automatic banknote handling device presses the banknotes stacked on the stacking plate against the pick-up roller, and uses the rotation of the pick-up roller to convey the banknotes, and passes through the feeding rollers that are meshed with each other and arranged oppositely. Separating from the gate rollers one by one and conveying to the conveying path, the output from the conveying monitoring sensor that monitors the conveying state of the bills on the conveying path is statistically processed, and the meshing amount between the feed roller and the gate roller is adjusted to achieve stable conveyance with almost no abnormality banknote delivery. As an example of such a technique, Japanese Patent...
