Automatic plate loading and unloading structure of computer to plate and plate loading and unloading method of structure

Abstract

The invention discloses an automatic plate loading and unloading structure of a computer to plate and a plate loading and unloading method of the structure. The structure comprises head clamps, tail clamps, a head clamp mechanical arm, a tail clamp mechanical arm, a head clamp sensor, a tail clamp sensor, a roller, a plate loading appliance, a head compression roller and a tail compression roller, wherein T-shaped grooves are formed in the surface of the roller and sleeved with the head clamps and the tail clamps in a sliding way, the plate loading appliance is in a fixed structure, and the head compression roller and the tail compression roller can swing around a public rotation centre. The core of the structure is the head clamps which are movable relative to the roller, and the fixed plate loading appliance. According to the structural combination disclosed by the invention, on one hand, the structure is simplified, the head clamps are not complex and the same as the tail clamps basically, and the fixed plate loading appliance is far simpler than a swinging plate support appliance; on the other hand, a simple plate material movement process is caused, and when the plate is uploaded, the plate material can directly move to a connection direction from the roller without need of swinging by the plate loading appliance and a reversion movement.

Description

technical field [0001] The invention relates to a PS plate direct plate-making machine for printing industry, which proposes a new, simple and effective printing plate transmission structure and its upper and lower plate method. Background technique [0002] The plate-to-plate machine (CTP) is an upgraded product of the laser phototypesetter. From a structural point of view, CTP is far more complicated than imagesetters. On the one hand, there is a difference in the optical system, and on the other hand, there is a difference in the plate. The hard aluminum-based PS plate of CTP leads to the complexity of the process and structure of the upper and lower plates. [0003] The PS board is fixed on the roller, and there must be a first board clip and a tail board clip. According to the current popular structure, the position of the head clamp relative to the drum is fixed, while the tail clamp is movable to adapt to the change of the upper plate and the plate width. Because th...

Problems solved by technology

On the one hand, this combination of structures adds redundant actions to the movement of the plates, and on the other hand, it complicates the structure

Because there are various transmission, detection, and alignment devices on the carrier, it is far more complicated than the first clamp
