technical info
Control and marking device for blanks not provided with film The system comprises of 2 fibre optic sensors placed in the window area on each lane. The detectors can be adjusted on a lateral direction across each lane according to the blank size and the window position. On detection of an missing window, a signal is sent via the machine computer directly to an electrically operated pneumatic valve which immediately adjusts the catch roll on the delivery conveyor in running direction in order to mark the shingled carton stream with the defective blank. The catch roll then returns to its normal operating position and continues the ore-set shingled stream. During the disruption of the shingled stream an audible alarm will be heard, thus drawing the attention of the operator to the faulty blank which must be removed prior to the arrival of the fault at the automatic stacker. The two-lane version works completely independent on each of the two lanes and would mark the corresponding faulty blank independently.
