ADHESIVE EXCESS/SHORT SUPPLY SIGNAL GENERATING DEVICE FOR BOX BLANK

摘要

PROBLEM TO BE SOLVED: To provide an adhesive excess/short supply signal generating device for box blanks which is capable of certainly eliminating rejects due to the excess/short supply of an adhesive without the manning of a dedicated operator. SOLUTION: The excess/short supply of an adhesive applied to the overlap width 18 of a corrugated fiberboard sheet 1 by the glue gun 19 of a folder gluer 3, is detected using a detector 10, and based on the detection results, the time when box blanks 2 whose excess/short supply of the adhesive is detected, arrive at a stacking device 7 is forecast using a controller 9. Further, an alarm lamp 12 is actuated at the time of the forecast to warn the generation of the rejects due to the excess/short supply of the adhesive applied to the box blanks 2. Thus it is possible to certainly eliminate the rejects of the box blanks 2 without the manning of a dedicated operator.
