Electronic automatic measurement device for length of bottle body

Abstract

The invention discloses an electronic automatic measurement device for the length of a bottle body, which is characterized in that a clearance eliminating and buffering assembly moves in a reciprocating manner between a zero-point reference block and a bottle bottom reference plate along an axis direction of the bottle body; the end, which is close to the bottle bottom reference plate, of the clearance eliminating and buffering assembly is contacted with an opening end of the bottle body so as to locate a measuring position I; the end, which is away from the bottle bottom reference plate, of the clearance eliminating and buffering assembly is contacted with the zero-point reference block so as to locate a measuring position II; the relative movement distance of a magnetic strip between themeasuring position I and the measuring position II is the movement amount of the magnetic strip; a magnetic sensor is static relative to the zero-point reference block, and the magnetic sensor is setin a mode of directly facing towards the magnetic strip so as to sense the movement amount of the magnetic strip; and a PLC (Programmable Logic Controller) analyzes and calculates the length of the bottle body according to the movement amount of the magnetic strip. According to the invention, a stepping motor is adopted to drive a linear module, the linear module drives a high-precision magneticbar code, the magnetic bar code senses the magnetic sensor, the magnetic sensor outputs an analog value, the PLC reads the analog value and converts the analog value into a numerical value, and the numerical value is displayed in a display.

Description

technical field [0001] The invention relates to an electronic automatic measuring device for bottle body length, which belongs to the technical field of automatic bottle length measurement auxiliary equipment. Background technique [0002] At present, for the bottles containing medicines, for the length of the bottles, in view of the constraints of technical equipment, the bottles generally adopt the method of random inspection, and the length of each bottle is not checked and tested, which will lead to possible There are poor workmanship products, causing users to check. When a substandard drug is loaded in the tube, the bottle body will be broken. When filling the bottle body, 300-500 pieces per minute, once the bottle body is broken, the broken bottle body residue is easy to mix in In the medicine, it causes significant loss of medicines and seriously affects the quality of medicines. [0003] Aiming at the above problems, the present invention provides an electronic aut...
