Electric moving goods shelf movement row anti-clamping safety inspection device

Abstract

The invention discloses an electric moving goods shelf movement row anti-clamping safety inspection device and relates to the technical field of moving goods shelves. The electric moving goods shelf movement row anti-clamping safety inspection device comprises a guide rail and a PLC; fixed goods shelves are fixedly connected to the two ends of the guide rail respectively; moving goods shelves aremovably connected to the middle part of the guide rail; receivers are fixedly connected to the inner sides of the fixed goods shelves respectively; emitters are fixedly connected to the two sides of the moving goods shelves respectively; a motor is fixedly connected to the bottom end of each moving goods shelf; and the PLC is internally provided with a data receiving module, a central processing unit and a data sending module. For the electric moving goods shelf movement row anti-clamping safety inspection device, by adopting a correlation type optical grating, output signals are diversified;a full model is firm in machine body, and a thin shell and the light transmittance of the highest level are adopted, so that the attenuation rate of the correlation distance is reduced; and by adopting a visual lens, the position of a shielding object can be clearly distinguished, and the signal output condition can be quickly recognized.

Description

technical field [0001] The invention relates to the technical field of mobile shelves, in particular to an anti-pinch safety inspection device for moving rows of electric mobile shelves. Background technique [0002] The mobile rack is easy to control, safe and reliable. Each row of shelves is driven by a motor, and the rollers installed under the shelves move along the track laid on the ground. Mobile shelves only need to set up one channel, the space utilization rate is extremely high, safe and reliable, and easy to move. According to the load-bearing, it can be divided into three types: heavy, medium and light. Generally, heavy-duty shelves use electric control to facilitate movement, and light and medium-sized shelves generally use hand cranks. move. Product features: It is suitable for warehouses with many types of inventory but low frequency of entry and exit, or warehouses with high inventory frequency but can enter and exit warehouses in the order of lanes.

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a safety inspection device for anti-clamping of electric mobile shelves, which solves the problem that the existing mobile shelves only install a pair of opposite-shooting sensors at the head and tail. It can only be detected when the mobile column is merged, and the item may have been squeezed when it is detected
