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

technical field [0001] The invention belongs to the technical field of packaging, and relates to a paper coil detector used for a paper feeding system of packaging equipment on high-speed production lines of light industries such as pharmaceuticals and food. technical background [0002] In the high-speed production lines of various industries in my country, the paper feeding speed of the paper feeding system of the packaging equipment is generally 600 m / min, and the feeding speed of some advanced packaging equipment can reach 1600 m / min. If the paper is discontinuous, discontinuous, dislocated, and broken, if it cannot be found and stopped immediately, packaging accidents will occur, resulting in product loss. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a paper coil detector with simple structure and convenient installation and maintenance, which can effectively detect the paper feeding quality and paper feeding status of the automa...
