Abstract

Provided is a paper supplying device that can discontinue control of a servo motor by a clutch or brake, and make the feeding speed of cardboard sheets to a printing device high-speed using a simple configuration. Columns of paper supplying rolls feed the lowest sheet of cardboard sheets, which are stacked and held on a paper supplying table, intermittently one sheet at a time to the printing device, and the paper supplying rolls are respectively connected, via a shaft, to individual servo motors. Each of the servo motors are controlled so as to be subjected to rapid acceleration in a synchronized manner from a stopped state of to the high-speed rotation speed of one cycle in which the paper supplying rolls feed the lowest sheet of cardboard sheets by making contact therewith, and the servo motors are each controlled so as to be caused to sequentially stop suddenly from the high-speed rotation speed when it has been determined that the paper supplying rolls are not making contact with the lowest sheet of cardboard sheets.

Description

technical field [0001] The invention relates to a paper feeding device for conveying stacked cardboards to post-processing devices such as printing devices or cutting devices, wherein the cardboards can be, for example, corrugated cardboards. Background technique [0002] A common paper feeding device has a paper feeding table and a guide plate. There is a gap between the guide plate and the paper feeding table. A number of thick cardboards are stacked on the paper feeding table. The front ends of these cardboards are in contact with the reference surface of the guide plate. The bottom layer of cardboard is attracted by the suction unit set under the paper feeding table, and is intermittently conveyed one by one from the gap of the guide plate to the post-processing device through a plurality of paper feeding rollers. Part of the peripheral surface of the paper feeding roller Exposed to the paper feeding platform (refer to Patent Document 1). In addition, the above-mentione...
