Transfer mechanism with jam detector |
(57) A mechanism for transferring a pair of side-by-side cartons from one processing station
to another, and accompanying device(s) for detecting any jam-up during the transfer,
should one occur for any reason. One embodiment includes a photoelectric unit, a vacuum
sensor, and a strobe signal for timing and detecting the presence of both signals
to shut down the machine if either signal is abnormal. Another embodiment includes
a second strobe signal for use as a back-up for the first strobe, or in lieu thereof,
for timing and detecting the photoelectric signal only.
