Traction film-pulling compensation detection device and method

Abstract

The invention discloses a traction film-pulling compensation detection device. The traction film-pulling compensation detection device comprises a traction mechanism arranged between a film covering machine and a punching machine and used for pulling a PVC forming film, and a detection piece arranged between the traction mechanism and the punching machine and used for sensing the edges of bubble caps on the PVC forming film, the traction mechanism is connected with a PLC control module used for controlling the traction stroke of the traction mechanism, and the PLC control module receives sensing information of the detection piece. The traction film-pulling compensation detection device has the advantages that the structure is simple, the cost is low, control is stable, and it can be ensured that the punching position does not exceed the allowable offset range so as to avoid mistaken punching or broken punching. A traction film-pulling compensation detection method comprises the following steps that S1, the standard distance L1 is set; S2, the actual distance L0 is determined; S3, the compensation distance L2 is determined; S4, the compensation distance L2 is subjected to compensation setting; S5, the punching machine is started to conduct punching so as to form the finished bubble caps; and S6, the steps S2 to S5 are executed circularly. The traction film-pulling compensation detection method is simple, practical and easy to implement.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical machinery and equipment, in particular to a traction film compensation detection device and a compensation detection method thereof. Background technique [0002] In the existing blister machine, after the PVC film is coated by the laminating machine, it is then punched into a finished blister by a punching machine. Forming) thermal expansion and contraction after cooling lead to excessive dimensional deviation, and cumulative errors in the traction process cause the punching size to exceed the allowable value of the deviation, causing the punching position to deviate and cutting errors or damage to occur. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a traction machine with simple structure, low cost, stable control, and the ability to ensure that the punching position does not ...
