Bobbin detector

Abstract

The invention belongs to the technical field of packing and relates to a coil paper detector used for a paper supply system of packaging equipment on a high speed production line of light industry. The detector consists of a base, a shell, a status display lamp, test light sources, a photoelectric induction device, a detecting head, an outgoing line plug-in and a detecting circuit board; wherein,the detecting head extends outside the shell, the front end of the detecting head is provided with a rectangular slot, and the two groups of test light sources and the photoelectric induction device are installed on the two walls of the slot in an opposite way; a detecting circuit comprises the test light sources, the photoelectric induction device, a signal amplification circuit, a data processing circuit, a signal output circuit and a status display circuit; when the tested wrapping paper normally passes through the rectangular slot of the detecting head, no control signal is output from the detector; when the tested wrapping paper has the phenomena of misplacement, discontinuity and failure crack, the control signal is output from the detector, and a controller and an actuator on the production line can be used for stopping the work of a host machine and the paper supply system, thus effectively ensuring the normal high speed running of the production line.

Description

Tray detector Technical field: The invention belongs to the technical field of packaging, and relates to a paper reel detector used in a paper supply system of a packaging equipment on a high-speed production line of light industry such as pharmaceuticals and food. Background technique: In the high-speed production lines of various industries in our country, the paper feeding speed of the paper feeding system of packaging equipment is generally 600 m / min. The paper feeding speed of some more advanced packaging equipment can reach 1600 m / min. The paper feeding system often occurs in production. If the paper is discontinuous, discontinuous, misplaced, or broken, if it cannot be found immediately and the machine is stopped, a packaging accident will occur, resulting in product loss. Summary of the invention: The purpose of the present invention is to provide a paper reel detector with simple structure and convenient installation and maintenance, which can effectively detect the ...
