Paper sheet separating device

Abstract

The present invention provides a paper sheet separator which can reduce the generation of inferior separation and inferior conveying caused by the effect of temperature variation in one day. The paper sheet separator is provided with an adjusting determining unit (181). The engaging amount between the paper feeding roller and door roller is determined to be adjusted when the year, month and day output by a calendar part (11), the time output by a clock part (12), and temperature output from a temperature sensing part (13) are in a preset range and furthermore the wasting rate calculated by a wasting rate calculating unit exceeds a preset threshold value. The engaging amount is adjusted through an engaging amount adjusting unit when the engaging amount between the paper feeding roller and door roller is determined to be adjusted by the adjusting determining unit (181).

Description

technical field [0001] The present invention relates to a paper sheet separation device for separating and leading out paper sheets stacked on a stage one by one. Background technique [0002] Conventional paper sheet separating devices pass the paper sheets stacked on the table into pressure contact with the pick-up roller, and at the same time rotate the pick-up roller to extract them. In order to separate the exported paper sheets one by one, the The paper feed roller and gate roller (gate roller), which are arranged in a box meshing shape, are separated one by one and sent to the conveying path. In the sheet separating device constructed in this way, when the amount of mesh between the feed roller and the gate roller is small, the phenomenon of overlapping conveyance (refeeding) of multiple sheets of paper will occur at the same time, and on the contrary, when the amount of mesh is large , it may happen that the paper cannot be fed out, and the paper may be damaged. In ...

Problems solved by technology

[0005] However, in the prior art described above, even if the meshing amount of the paper feed roller and the gate roller is regularly adjusted to an appropriate amount based on the information indicating the separation state and conveyance state of the sheets within a predetermined period, the meshing will still be caused by the meshing. The amount varies based on the temperature of the paper feed roller and gate roller, especially in winter mornings, the temperature in the room where the sheet separation device is installed and the temperature inside the device are low, and the temperature of the paper feed roller and gate roller is also low On the other hand, as the indoor temperature and the temperature in the device due to the air conditioner rise, the temperature of the paper feed roller and the gate roller also rises, so there is a possibility that the separation of paper sheets may be affected by the influence of the daily temperature change. and problems that may occur during transportation

[0006] In view of such a problem, even if the control is performed based on the indoor temperature and calendar information (refer to JP-A-8-5060), it is difficult to control the paper sheet separation device due to changes in installation conditions such as the installation place and working hours of the sheet separation device and annual temperature changes. Adjust the amount of engagement between the paper feed roller and the gate roller to an appropriate amount, and even if there is no problem in the separation state and conveyance state of the sheets, the engagement amount may vary according to the room temperature and calendar information , resulting in poor separation and poor transport of paper sheets

[0007] In addition, when the conveyance state of the sheets led out to the conveyance path by the paper feed roller and the gate roller is monitored by the conveyance state monitoring device, and the output of the conveyance state monitor is statistically processed, there may be Before the paper sheets reach the specified number of sheets after a long period of time, the meshing amount between the paper feed roller and the gate roller cannot be adjusted to an appropriate amount, so that fine adjustment cannot be performed
