A continuous positioning detection device for preforms

Abstract

The invention provides a continuous positioning detection device for preforms, which includes a bracket, a photographing detection device, a preform conveying device, an interval transfer device and a detection conveying device. side; the detection and conveying device includes a rotating assembly and several preform spin limit assemblies; by setting an interval transfer device, the preforms conveyed from the preform conveying device are arranged at intervals in the further transmission process, and Cooperate with the detection and conveying device to rotate and clamp the sorted preforms during the rotary motion, and then take pictures and detect at the photo-detection device. The detection method realizes the detection of the thread integrity of the bottle preform and the bottle cap and simultaneously performs the photo detection of the defects of the bottle body of the preform, which solves the technical problems of low efficiency and high cost in the preform detection process in the prior art.

Description

technical field [0001] The invention relates to the field of preform manufacturing and production, in particular to a continuous positioning detection device for preforms. Background technique [0002] In the bottle production line, the quality of the preform is usually at the end of the line. The preform imaging and rejecting device is installed from the preform unscrambling system to the preform track, which needs to be transferred by a separate mechanism. Not only is the cost high, the equipment is complicated, and the area is large, but the key problem is that it is inconvenient to operate and is not conducive to on-site observation. maintain. [0003] Therefore, for technicians, the problem to be solved urgently is to develop a preform imaging detection and rejection device with reasonable design. The installation position is determined according to the output and the size of the bottle mouth, and the unqualified preforms are eliminated through the cooperation of the ...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a continuous positioning detection device for preforms. By setting up an interval transfer device, the preforms transported from the preform conveying device are arranged at intervals during the further transmission process, and cooperate with the The detection and conveying device rotates and clamps the preforms that have been sorted during the rotary motion, and then takes a photo to the photo inspection device for photo inspection, and the preform spin limit assembly realizes the inspection of the thread of the bottle cap bottle mouth during photo inspection. , to realize the detection of the integrity of the thread integrity of the preform and cap, and at the same time to carry out the photo inspection of the defects of the bottle body of the preform, which solves the technical problems of low efficiency and high cost of the preform detection process in the prior art
