Abstract: A copying or printing machine comprising a microcomputer, a memory having a sequence control program for accomplishing copying or printing operation, and a processing unit operative for reproducing a copy. The copying machine is provided with a delivering device for delivering the copy, a sorter for sorting successive copies delivered from the delivering device and a jam detector for detecting a jamming of a copy in the sorter. The delivering device is covered with a cover which may be opened so that an operator may access the delivery device.When a malfunction in the sorter is detected by the jam detector, the microcomputer stops the operation of the copying machine. It is necesary for the operator to remove the copy detected by the jam detector and to close the cover after opening it once for restarting the operation of the copying machine. The microcomputer enables the copying machine to restart after it detects that the copy detected by the jam detector is cleared and the cover is closed.

The sorter may be formed of one or more sorter portions arranged serially and is provided with a memory register for memorizing information corresponding to the number of sheets to be inserted manually, a count register for counting the number of sheets for manual insertion, and a circuit for inhibiting the manual insert operation for a predetermined period of time after the contents in the memory register becomes equal to the contents in the count register, thereby attaining the precise and reliable collation and sorting of the sheets to be inserted as covers and partitions.

Abstract: A collator includes a series of twenty bins arranged in parallel with each other, a copy feeding member for feeding copies supplied from a copying machine along inlets of the successive bins, first and second deflecting devices arranged at the uppermost two bins for delivering the copies into the uppermost two bins and a distributor movable between the third bin and the twentieth bin for delivering the copies into the bins. The collator can treat the copies in a job separation mode in which all copies of each documents are delivered into respective bins in succession, while the distributor is advanced bin by bin in response to a distributor advance signal produced by a variable timer which is actuated upon detection of the rear edge of the last copy of an Nth original by an entrance switch to set a time period represented by b+(N-1).times.a/V.sub.1, wherein a is a pitch between successive bins, b is a distance from the entrance switch to the first bin and V.sub.1 is a copy feed speed in the collator.

Abstract: A sophisticated collator having a general purpose microprocessor with a stored program is capable of intercommunicating with a sophisticated photocopier. In most operations, the collator functions as a slave to the photocopier. It processes a collator task by receiving and processing signals from several sensors positioned about the collator. A manual insertion assembly allows entry of sheets into the collator from a source other than the photocopier. Proofed pages can be re-fed for collating, or jobs from a second source may be processed. Thus the collator need not be a slave only to the photocopier. A second vacuum belt reduces problems of transporting wide paper. Diverting fingers may contact the conveyor system to allow sheets to pass over a bin into additional bin units attached to the sophisticated collator.

Abstract: A plurality of bins (31) to (40) are divided into two groups which are used alternatingly when a number of copies N to be collated exceeds the number of bins, thus allowing a copying machine to operate continually and further allowing an operator to remove the collated copies from one group while the copies are being collated in the other group. When the number of pages P of a document exceeds a predetermined number, the first group is defined to contain more bins than the second group, thereby reducing the number of times each page must be fed to the copying machine. A unique sensor arrangement (151) senses for feed failures using only two sensors (78), (79).

Abstract: The present invention is directed to a photocopier collator wherein a movable paper chute is disposed between the discharge slot of a photocopy machine and the entry point of a plurality of bins mounted adjacent thereto. The movable paper chute is designed to receive copies from the photocopy machine and to direct them successively into one of the bins. The chute is successively diverted to each of the predetermined number of bins by means of a pulse from the photocopy machine which indicates that a copy has been produced and discharged to a bin. The pulse actuates a solenoid which controls a cam latch thereby releasing a follower, which is attached to the movable paper chute. Actuation of the solenoid successively lowers the paper chute to divert successive sheets of photocopies to each of the predetermined number of bins. After the pulse from the photocopy machine has actuated the solenoid, the latch is pulled away from the solenoid by means of a spring.

Abstract: Sheets are delivered to receptacles by a traveling distributor which includes an incrementally movable carriage. A continuous loop belt or belts such as in a vacuum plenum transport convey the sheets to the carriage where a roller arrangement on the carriage diverts the belts and thus the sheets into a direction in alignment with the receptacles. The rollers then divert the belt away from the receptacles so that the sheets continue into the receptacles. The rollers are mounted so as to place the belt or belts in tension during normal operation but are movable to relieve the belt tension to facilitate paper removal from the belt in jam clearance procedures.

Abstract: A heated metal plate drying system for drying either green veneer or partially dried veneer can have a plurality of modular hot presses mounted on a frame. At a loading station, individual sheets of veneer to be dried or redried are fed into a hot press, and at an unloading station the dried veneer sheets are unloaded from the system. Within each individual modular hot press, a direct contact drying process occurs that functions to reduce the moisture content of a veneer sheet down to the desired uniform level such as within a range of from 1 to 10%. The drying process accepts veneer of different species, thickness, and beginning moisture contents and the controlled process variables include contact time, temperature and pressure.Each individual modular press can be multi-opening and has the ability to open and close on command. Specially designed heated metal plates are part of each press and each plate has substantially parallel grooves on at least one surface.

Abstract: A movable self-contained deflector unit for directing sheets into the paper bin of a multi-bin collator. A first motor is mounted on the frame of the deflector unit to drive transport rolls also mounted thereon. The transport roll provides the final impetus for moving the sheets into the collator bin. A second motor is mounted on the frame of the deflector unit to drive the unit to a selected bin. The motor may be reversible in order to approach a selected bin from either direction. Alternatively, movement of the deflector unit in the second direction may be obtained through a spring motor wound through deflector unit movement in the first direction. Speed of the spring-driven deflector unit is controlled by dynamic braking of the second motor. This collator may interact with a copier machine to provide semi-automatic duplexing and the speed of the transport rolls may be synchronized with the speed of the copier for moving copy sheets into bins while the sheet is still in the final processing station.
