If the packager shuts down, the buckets simply are held in the -stand-by station 86 rather than passing through the loading station without being filled. Also, the demand conveyors 20 act as buffers between the packagers l7 and the accumulating conveyor 21 and avoid the need of synchronizing the packagers with the accumulating conveyor and the cartoner 24 so that the packagersand the cartoner may operate independently of one another. The demand conveyors thus increase the versatility and flexibility of the packaging system.

  • each packager may continue to operate for a short period of time after the cartoner shuts down and thus it is not necessary to interrupt operation of the packagers if the cartoner is shut down only momentarily.
  • each timing conveyor operates at a higher speed than the associated demand conveyor 20, the timing conveyor is capable of disposing of the backlog of buckets 58 that builds up in the storage area when the cartoner 24 is shut down. Also, the speed dif ferential between the demand and timing conveyors periodically results in a bucket 58 being absent at the first transfer station 96 when a pusher lug arrives at the transfer station. Under such circumstances, the lug will pass between the transfer stations 96 and 97 without advancing a bucket 58 and thus isolated ones of the buckets 29 on the accumulating conveyor 21 will not be filled.
