Abstract
A collating system having a plurality of feeders to release enclosure materials onto a deck and a plurality of pusher finger pairs moving along the deck for collating the released materials. The pusher finger pairs are mounted on a pair of moving belts at pre-determined positions. A sensing device is used to monitor whether any pusher finger is missing, broken or out of alignment, thereby rendering a pusher finger pair non-functioning. If a pusher finger pair is not functioning, the cell or pocket associated with that pusher finger pair will be marked “damaged” so that the feeders release enclosure materials only to the cells associated with functional pusher finger pairs.
Claims13
A collation system for collating generally flat items, comprising:
- an upstream end;
- a downstream end;
- a deck extending from the upstream end to the downstream end;
- a plurality of feeders, each positioned relative to the deck so as to be able to release the items onto the deck;
- a continuous moving member running from the upstream end toward the downstream end;
- a plurality of pusher pairs mounted on the moving member, each pair disposed in a pre-determined position and associated with a section of the moving member in front of said pair for pushing from the upstream end to the downstream end the items released into said section by the feeders;
- a sensing mechanism to determine whether a pusher pair is functional;
- and
- a controller coupled to the sensing mechanism and controlling the feeders to release the items only onto the sections of the moving member associated with functional pusher pairs.
A method of improving the performance of a collation system for collating generally flat items, wherein the collation system comprises:
- an upstream end;
- a downstream end;
- a deck extending from the upstream end to the downstream end;
- a plurality of feeders positioned relative to the deck so as to be able to release the items onto the deck;
- a continuous moving member running from the upstream end toward the downstream end;
- a plurality of pusher pairs mounted on the moving member, each pair disposed in a pre-determined position and associated with a section of the moving member in front of said pair for pushing from the upstream end to the downstream end the items released into said section by the feeders, said method comprising the steps of:
- sensing the position of the pusher pairs;
- determining whether the pusher pairs are functional as to said pushing based on the sensed positions;
- releasing the items only onto the sections of the moving member associated with functional pusher pairs;
- marking the sections to indicate whether the sections are functional so that the releasing of the items is based on said marking.
A mail inserting system for inserting enclosure materials into envelopes for mailing, said system comprising:
- an envelope insertion section for providing the envelopes for insertion;
- a collation section for collating the enclosure materials, the collation section having:
- an upstream end,
- a downstream end adjacent to the envelope insertion station,
- a deck extending from the upstream end to the downstream end,
- a plurality of feeders, each positioned relative to the deck so as to be able to release the enclosure materials onto the deck,
- a continuous moving member running from the upstream end toward the downstream end, and
- a plurality of pusher pairs mounted on the moving member, each pair disposed in a pre-determined position and associated with a section of the moving member in front of said pair for pushing from the upstream end to the downstream end the enclosure materials released into said section by the feeders so as to convey the pushed enclosure materials to the envelope insertion section for insertion;
- and
- a sensing mechanism, positioned relative to the deck of the collation section, to determine whether a pusher pair is functional;
- a controller coupled to the sensing mechanism and controlling the feeders to release the enclosure materials only on the sections of the moving member associated with functional pusher pairs.
