In step S4, when the strapping band recognition photosensor 13 detects the third strapping band 43, the strapping band recognition photosensor 13 transmits a signal to the control device 5, and the control device 5 performs counting while stopping the second timing and starting the third timing.
Specifically, in step S6, when the off-position photoelectric sensor 12 cannot detect the box 3, the off-position photoelectric sensor 12 transmits a signal to the control device 5, and the control device 5 receives a falling edge signal of the off-position photoelectric sensor 12, and then ends the counting of the packing belts of the box 3 this time and clears the third time.
According to the automatic detection method for the packing belt, disclosed by the invention, the deviation value of the joint 401 of the packing belt, the deviation value of the distance of the packing belt and the quantity of the packing belt can be automatically detected after a finished product is packed, so that on one hand, the situation that the joint 401 of the packing belt is unqualified in deviation, unqualified in distance deviation, missed packing, multiple packing and the like directly flow into a finished product warehouse to bring hidden danger to after sale can be avoided; on the other hand, the packing quality and the packing strength can be improved. In addition, the first preset deviation value, the second preset deviation value and the preset number of the packing belts can be switched at will, and the method is suitable for different customer requirements.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected by one skilled in the art without departing from the spirit and scope of the invention, as defined in the appended claims.
