Definitions

  • This invention relates generally to transfer mechanisms and, more particularly, to means for detecting whether or not the product being handled has actually been transferred.
  • a general object of the invention is to provide an improved means for detecting a product transfer at a predetermined transfer point.
  • Another object of the invention is to provide novel electronic means for detecting the transfer of a paperboard carton at a predetermined transfer point in a forming, filling and sealing machine.
  • a further object of the invention is to provide electronic means coupled with photoelectric and vacuum sensing means for detecting any jam-up of a paperboard carton at a particular transfer point in a packaging machine.
  • Still another object of the invention is to provide means consisting of a photoelectric sensor, a vacuum sensor, and at least one strobe signal adapted to detect the presence of signals from both sensors.
  • Figure 1 illustrates a loading type of transfer point as may be used to transfer bottom sealed cartons 10 two-at-a-time from an indexing conveyor means 12, moving from left to right in Figure 1, to resilient carriers 14 moving at a right angle with respect to the conveyor.
  • the carriers each consist of an inverted U-shaped bracket whose side walls are normally urged toward one another until spread slightly to admit and retain a carton 10 therebetween.
  • the cartons 10 typically will have been stripped from a mandrel (not shown) and placed on a stationary rail 16 extending laterally from between a pair of parallel endless conveyors 12 mounted around sprockets 18, as more fully shown and explained in U.S. patent no. 4,566,251, issued January 28, 1986.
  • the transfer of the pair of cartons 10 from the conveyor 12 to the carriers 14 is accomplished by a lifting mechanism 20, having a support platform 22 above which the cartons are positioned as they leave the rail 16.
  • the lifting mechanism 20 extends between the conveyors and raise each two side-by-side cartons vertically upwardly into the spring biased carriers 14.
  • a conveyor 24 associated with the carriers 14 indexes the cartons onto support rails 26 for the start of a further process step, such as the sterilization process.
  • Sensors, represented at 28, are mounted on the support platform 22 and serve to detect an increase in the force necessary to lift the cartons 10 into the carriers 14.
  • This sensor can be a load cell, a strain gauge device, a spring loaded plate and proximity switch, or a similar device that is capable of an instant response to an increase in the force needed to lift the carton.
  • This response or increased force load would be sensed by the control system and immediately stop the conveyor 24 to prevent further jamming of the carton, damage to the machine, and lost downtime.
  • a carton jammed at this point in the machine can be easily removed without major machine problems. Otherwise, a jam in the machine could cause a compromise of the commercial sterility, and complete machine resterilization may be required, which involves a substantial amount of downtime.
  • An unloading device 34 serves to raise a pair of vacuum cups 36 upwardly to engage the pair of cartons 10 being held in the carriers 14.
  • the vacuum cups engage the bottoms of the cartons and pull them down onto a stationary rail 38 and into compartments 40 between the conveyors 30 which will be indexed for the further processing of final filling and sealing of the cartons.
  • a pair of photoelectric sensors 42 will detect the presence of two cartons as the latter move into the unload station. This fact is recorded and stored in the logic system of the machine control unit.
  • the vacuum cups 36 are operatively connected to vacuum sensors 44, which serve to detect the increase in vacuum after the unloading device has raised the cups 36 to grip the bottoms of the cartons. This event is also noted in the machine control unit, and as the unloading device 34 is cycled and the two cartons are pulled into the conveyor compartments 40, a comparison is made of the signals to determine if cartons that were sensed in the carriers 14 had successfully passed by the photoelectric sensors 42, and had been subjected to sufficient vacuum, as sensed by the vacuum sensors 44, to be pulled into receiving compartments 40. If both signals are not correct within a predetermined time period, the machine control system will be caused to stop, thereby preventing jamming of the cartons at this transfer station.
  • Figure 3 shows the logic and timing of the photoelectric sensor 42 (PES) and the vacuum sensor 44 (VS) , a first strobe signal that is used to detect the presence of both signals, and a second strobe signal that is used to detect the presence of only the PES signal. A number of conditions will cause the machine to be stopped:
  • the strobe signals are unrelated to the PES or the VS signals, and are developed from other timing signals in the machine and synchronized to the conveyor movements.
  • the second strobe signal f is optional and may be used either to back up the action of the first strobe signal c, or in lieu thereof.
  • This second strobe signal f serves to detect that the PES signals a and b have shown that both cartons 10 have been removed, i.e., moved completely past the photoelectric sensors 42 and, hence, have been deposited in the compartments 40 of the conveyors 30. Should any one carton not pass by the photoelectric unit, the pulse would continue as represented by the dash lines in Figure 3.
  • the invention provides a novel and efficient means for assuring that transfers of a product, such as paperboard cartons, have occurred at the inlet and outlet of crucial processing operations, such as a sterilization chamber, wherein jam-ups would cause substantial downtime, not only in unjamming and possible machine damage, but in complete resterilization time before the machine can be restarted.
