Detection method and detection device for hanging ring of bottle blowing machine

Abstract

A hanging ring detection method and a hanging ring detection device of a blow molding machine are disclosed. The detection method comprises: arranging a bottle blank detector and a hanging ring detector in the direction vertical to the transfer direction of an infusion bottle; detecting time points t1 and t2 corresponding to two end points in the diameter A of a bottle blank in the transfer direction during transferring by the bottle blank detector; detecting time points t3 and t4 corresponding to two end points in the diameter B of the hanging ring in the transfer direction during transferring by the hanging ring detector. When the hanging ring detector cannot detect data, the hanging ring in the detected infusion bottle is missed to be buckled; and when a difference value of t3 and t1 is unequal to a difference value of t2 and t4 in the detected data, the hanging ring in the detected infusion bottle is misplaced. The detection method and device provide high sensitivity and stable equipment performance, reduce labor intensity and quality risk, and avoid human interference in the working process by automatic detection. During the operation, the device detects the hanging ring of the transferring bottle blank by two sensors.

Description

technical field [0001] The invention relates to a detection method and a detection device for a hanging ring of a bottle blowing machine. Background technique [0002] In the production of large infusions, the process of blow molding machines has gradually adopted the method of automatic lifting rings instead of manual lifting rings, but sometimes there will be cases where the rings are missing or the buckles are misplaced, resulting in the corresponding plastic infusion bottles being unqualified. In the past, there was no good way to detect the above-mentioned problems in production in a timely manner. Therefore, personnel can only be arranged to carry out manual inspections, and timely make up buckles or adjustments when missing or misplaced buckles are found. However, it is difficult for operators to keep If you are in a good mental state, there will still be infusion bottles without rings or misplaced rings flowing into the next process, resulting in quality defects in i...
