AI Technical Summary

Benefits of technology

This solution enables synchronized conveyance of sheets between upstream and downstream apparatuses, even when the sheet is straddling, reducing delays and ensuring smooth operation by coordinating the drive of conveying rollers through precise control signals.

Problems solved by technology

In a system in which plural apparatuses for conveying paper sheets are interconnected, in the case of stopping a paper sheet in a state of straddling the upstream apparatus and the downstream apparatus or resuming conveyance of the paper sheet stopped in the state of straddling the upstream apparatus and the downstream apparatus, a conveying roller of the upstream apparatus is driven by the controller of the upstream apparatus and a conveying roller of the downstream apparatus is driven by the controller of the downstream apparatus, and thus it is difficult to synchronize conveyance between these apparatuses.
Also, if the controller of one of the upstream apparatus and the downstream apparatus drives the conveying rollers via the controller of the other apparatus, a delay occurs and it is difficult to achieve the synchronization.

Embodiment Construction

[0017]Hereinafter, one or more embodiments of a sheet conveying system and an image forming system according to the present invention will be described with reference to the drawings. However, the scope of the invention is not limited to the disclosed embodiments.

[0018]FIG. 1 is a configuration diagram showing an example of a sheet conveying system of the present embodiment. In this example, in an image forming system 110A including a sheet feeding apparatus 100A, an image forming apparatus 10A, a finishing apparatus that is not illustrated, and so forth, a sheet conveying system 1A of the present embodiment constitutes a conveyance path between the sheet feeding apparatus 100A and the image forming apparatus 10A through which a paper sheet P is conveyed.

[0019]The sheet feeding apparatus 100A is an example of an upstream apparatus, and includes a conveyor 101 that conveys a paper sheet P and a single or plural sheet feeding trays 102 that store paper sheets P. The sheet feeding appa...

Abstract

A sheet conveying system includes: an upstream apparatus provided on an upstream side in a conveyance direction of a paper sheet; a downstream apparatus provided on a downstream side of the upstream apparatus; an upstream conveyor that conveys the paper sheet; an upstream driver that drives the upstream conveyor; a downstream conveyor that receives the paper sheet conveyed from the upstream conveyor, and conveys the paper sheet received from the upstream conveyor; a downstream driver that drives the downstream conveyor; an upstream controller that is connected to the upstream and downstream drivers; and a downstream controller that is connected to the downstream and upstream drivers, wherein the sheet conveying system switches control on the basis of sheet information between first control in which the upstream controller controls the upstream and downstream drivers and second control in which the downstream controller controls the downstream and upstream drivers.

Description

[0001]The entire disclosure of Japanese patent Application No. 2016-242684, filed on Dec. 14, 2016, is incorporated herein by reference in its entirety.BACKGROUNDTechnological Field[0002]The present invention relates to a sheet conveying system and an image forming system in which plural apparatuses are interconnected and which conveys a paper sheet.Description of the Related Art[0003]As a configuration in which a paper sheet is conveyed by driving a conveying roller by a motor, a technique in which a slave central processing unit (CPU) for motor control is provided in addition to a host CPU and the host CPU controls the motor via the slave CPU by, in response to a trigger command issued by the host CPU, the slave CPU rotating the motor on the basis of acceleration information stored in a built-in random access memory (RAM) has been proposed (for example, see JP 3096114 B2).[0004]In addition, a technique in which a CPU that outputs a motor control command outputs motor selection inf...
