Collator

Claim 2

A sophisticated collator capable of intercommunicating with a computer of a computer-controlled photocopier to receive job commands from the photocopier regarding the mode and size of a collating job to be transmitted to the collator directly from the photocopier, to store the job commands in a buffer, and to control the collating operations of the collator based upon the job commands while reporting progress of the collating operations to the photocopier during the operation, comprising: (a) a sheet conveyor system for receiving sheets from the photocopier and for transporting the sheets to trays in a bin unit during the collating operation, the system including a movable deflector means for deflecting the sheets from a conveyor into predetermined trays; (b) a logic control means, having a programmable computer with a stored program, for communicating with the computer of the photocopier and for controlling the collating operations in the collator upon receipt of the job commands from the photocopier, including a buffer for storing the job commands to remove dependency upon the photocopier for continued checking of the desired collating operation, the logic control means being connected to means for sensing collating operation information within the collator to monitor the collating operation and being connected to the conveyor system to control operation of the conveyor system; (c) means for sensing the entry of a sheet into the collator from the photocopier and for signalling the entry to the logic control means so that the logic control means can count the entry of the sheet and monitor the passage of the sheet along the conveyor system to a predetermined tray selected on the basis of the job commands; (d) means for identifying the individual trays of the bin unit by counting the operation of the deflector means at each tray so that the position of the deflector means ready to deflect sheets to a tray represents the position of the tray; and (e) means for sensing entry of the sheet into the predetermined tray and for signalling the entry to the logic control means so that the logic control means can count the entry and command continued collating operations based upon the entry, such as changing the deflector means or signalling a jam to the photocopier.

Claim 3

The collator of claim 1 wherein the conveyor system includes a laterally spaced, double vacuum belt system to better control wide paper.

Claim 4

The collator of claim 1, further comprising manual insertion means connected with the conveyor system for receiving sheets from a source other than the photocopier, for signalling the receipt to the logic control means, and for conveying the sheets to the conveying system upon the command of the logic control means, wherein the manual insertion means may be used to collate sheets in the collator independently of job commands generated in the photocopier.

Claim 5

The collator of claim 1, further comprising means for detecting whether there are any sheets in any tray of a bin unit and for signalling whether there are any sheets in any tray to the logic control unit so that the logic control unit can determine whether the job command is able to be completed.

Claim 6

The collator of claim 1, further comprising means for attaching additional bin units to the collator, and means for detecting attachment of additional bin units and for signalling the attachment to the logic control means so that the logic control unit can control the additional bin units when controlling the collator operations.

Claim 7

The collator of claim 5, further comprising diverter fingers in each bin unit, controlled by the logic control means, for diverting sheets on command from the logic control means over a bin unit and into an adjacent bin unit.

Claim 8

The collator of claim 1, further comprising a proof tray for receiving sheets in one mode of operation and means for proofing, controlled by the logic control means, for diverting a sheet from the conveyor system to the proof tray upon command from the logic control means.

Claim 9

A sophisticated collator capable of intercommunicating with a computer of a computer-controlled photocopier to receive job commands from the photocopier regarding the mode and size of a collating job to be transmitted to the collator directly from the photocopier, to store the job commands in a buffer, and to control the collating operations of the collator based upon the job commands while reporting progress of the collating operations to the photocopier during the operation, comprising: (a) a sheet conveyor system for receiving sheets from the photocopier and for transporting the sheets to trays in a bin unit during the collating operation, the system including a deflector means for deflecting the sheets from a conveyor into predetermined trays; (b) a logic control means having a programmable computer with a stored program for communicating with the computer of the photocopier and for controlling the collating operation in the collator upon receipt of the job commands from the photocopier, including a buffer for storing the job commands to remove dependency upon the photocopier for continued checking of the desired collating operation, the logic control means being connected to means for sensing within the collator to monitor the collating operation and being connected to the conveyor system to control operation of the conveyor system (c) means for sensing the entry of a sheet into the collator from the photocopier and for signalling the entry to the logic control means so that the logic control means can count the entry of the sheet and monitor the passage of the sheet along the conveyor system to a predetermined tray selected on the basis of the job commands; (d) means for identifying the individual trays of the bin unit by counting the operation of the deflector means at each tray so that the position of the deflector means ready to deflect sheets to a tray represents the position of the tray; (e) means for sensing entry of the sheet into the predetermined tray and for signalling the entry to the logic control means so that the logic control means can count the entry and command continued collating operations based upon the entry, such as moving the deflector or signalling a jam to the photocopier; (f) manual insertion means connected with the conveyor system for receiving sheets from a source other than the photocopier, for signalling the receipt to the logic control means, and for conveying the sheets to the conveying system upon a command from the logic control means, wherein the manual insertion means may be used to collate sheets in the collator independently of job commands generated in the photocopier; (g) means for attaching additional bin units to the collator; (h) means for detecting attachment of additional bin units and for signalling the attachment to the logic control means so that the logic control means can control the additional bin units when controlling the collator operations; (i) proof tray for receiving sheets in one mode of operation and means for proofing, controlled by the logic control means, for diverting a sheet from the conveyor system to the proof tray upon command from the logic control means; (j) means for diverting sheets from one bin unit into an adjacent bin unit.
