Auxiliary paper collecting and lifting device and working method for same

Abstract

The invention discloses an auxiliary paper collecting and lifting device which is characterized by comprising a motor, chains, chain transmissions, a limiting device and an auxiliary paper collecting device. The motor is connected with the chain transmissions, the chain transmissions are connected with the chains, the chains are connected with the auxiliary paper collecting device, and the limiting device is mounted at vertical movement extreme positions of the auxiliary paper collecting device. A working method for the auxiliary paper collecting and lifting device includes that after paper collected by a main paper collecting device is full, paper collecting work is stopped, and auxiliary paper collecting fork levers of the auxiliary paper collecting device stretch out to carry out temporary paper collecting work; when paper collected by the auxiliary paper collecting device is nearly full, the motor rotates to drive the auxiliary paper collecting device to move downwardly; when the auxiliary paper collecting device reaches the lower extreme position, the motor stops rotating; after the main paper collecting device returns to work, the auxiliary paper collecting fork levers are retracted, the motor rotates reversely and the auxiliary paper collecting device ascends; when the auxiliary paper collecting device reaches the upper extreme position, the motor stops rotating. The auxiliary paper collecting and lifting device and the working method have the advantages that the auxiliary paper collecting device can be vertically adjusted, the paper collecting quantity is increased, unnecessary shutdown operation is reduced, and the production efficiency is improved.

Description

(1) Technical field: [0001] The invention is suitable for printing machinery and equipment, especially for the occasion of paper collection. (2) Background technology: [0002] The usual sheet-fed printing equipment is equipped with a device for collecting paper. The paper delivery device is generally divided into a main paper delivery device and a secondary paper delivery device. Auxiliary device for collecting paper. When the main paper delivery device collects the paper to a certain height, it needs to send the paper stack out of the machine. At this time, the main paper delivery device will stop working. The paper device replaces the main paper delivery device for paper delivery. [0003] The auxiliary paper delivery device in the prior art can only realize the extension and retraction actions at a fixed height. When the paper delivery work is required, it is extended to collect paper. When the main paper delivery device is working, the auxiliary paper delivery fork le...

AI Technical Summary

Problems solved by technology

This kind of fixed-height auxiliary delivery device has some problems in actual production. For example, when the collected paper is thick, it is easy to fill the auxiliary delivery device when the equipment is running at high speed. If the device cannot return to its original position for paper delivery, it must be stopped at this time, or the speed of the equipment should be lowered during auxiliary paper delivery to allow enough time for the main paper delivery device to export the paper stack, which obviously affects Productivity
