Overturning positioning device for printed matter

Abstract

The invention discloses an overturning positioning device for a printed matter. The device comprises a bottom frame and a loading rack, wherein a bed frame is mounted on the top end of the bottom frame, and an overturning plate is movably connected to the top end of the bed fame; a piston rod is movably connected to the right side of the bottom end of the overturning plate; an arc-shaped plate is fixedly mounted at the bottom end of the piston rod; a servo motor is mounted at the bottom end of the bottom frame; a cam which is in match with the arc-shaped plate is arranged at the right side of the servo motor. According to the overturning positioning device for the printed matter, the piston rod, the arc-shaped plate and the cam are matched; the servo motor can drive the cam to rotate under the matching of a coupling and a rotating roller; the cam is in match with the arc-shaped plate to drive the piston rod to move in a piston sleeve so as to enable the overturning plate to repeatedly overturn on the bed frame, and as a result, the printed matter can fall down onto the loading rack; an air pump can work to generate air, and the air is sprayed out through an air spraying port so as to drive the printed matter to quickly fall down onto the loading rack; the overturning positioning device can continuously work to overturn and uprightly position the printed matter.

Description

technical field [0001] The invention relates to the technical field of printing machinery, in particular to a device for reversing and placing printed matter. Background technique [0002] Printed matter and printed matter are flat paper objects. After the printed matter passes through the printing process of different equipment or other processing steps, it must be collected in batches at the output end of the equipment. Multiple pieces of printed matter are stacked continuously. After reaching a certain amount, they are removed and resumed. Stacking, because the printed matter needs to go through a variety of processes, there will be a variety of printed materials on the printing surface, and it cannot be stacked immediately after the process to avoid affecting the quality of the printed surface, so it is necessary to turn the printed matter upright to protect the printed matter, but the traditional The operation steps can not be completed well, often require multiple manu...

[0002] Printed matter and printed matter are flat paper objects. After the printed matter passes through the printing process of different equipment or other processing steps, it must be collected in batches at the output end of the equipment. Multiple pieces of printed matter are stacked continuously. After reaching a certain amount, they are removed and resumed. Stacking, because the printed matter needs to go through a variety of processes, there will be a variety of printed materials on the printing surface, and it cannot be stacked immediately after the process to avoid affecting the quality of the printed surface, so it is necessary to turn the printed matter upright to protect the printed matter, but the traditional The operation steps can not be completed well, often require multiple manual operations, and can not be turned up in time, affecting the printing effect and quality, in the prior art, for example, the invention patent with application number 201520679819. There is a rotatable turning plate on the upper side. The turning plate protrudes and extends to the other side of the body with several support rods. The supporting rods tilt up with the turning of the turning plate. On the side, the holding frame is vertically inclined to the side facing away from the body. The holding frame and the top plane of the body form an obtuse angle. In actual use, it cannot work continuously and the printed matter can be turned up and placed on its own
