Abstract: When paper jam occurs during copy operation, the paper feed opening (which is one of the paper feed openings 1a to 1d) in which the paper jam occurs is determined, and thus, the number of occurrences of paper jam is counted for each of the paper feed openings. When the number of occurred times of paper jam exceeds a predetermined number, the paper feed opening concerned is forbidden to be used until maintenance or other repair work is completed. If the preferred feed opening (1a) assigned the first priority is forbidden to be used, another preferential feed opening is selected based on the numbers of occurred times of paper jam in the other paper feed openings (1b to 1d). On the other hand, when paper jam occurs, a paper jam occurrence ratio is calculated for each paper feed opening based on the number of sheets and the number of occurred times of paper jam counted.

Abstract: A feed system for large copy sheets to feed such sheets through a copying machine, such as a white print, blue print or other copying machine, a computer printing machine, a pen plotter of other vector plotter, or raster plotter, or a printing machine. A supply roll is provided with copy sheets wound on the supply roll in an interleaved or overlapping array. A pair of support rollers form a cradle for freely supporting the supply roll, with at least one of the support rollers being driven. A printing roller grasps a copy sheet as the sheet is fed from the supply roll. A sensor stops the driven support roller and, in turn, the supply roll at a given time in a predetermined cycle whereby the printing roller can pull the fed sheet away from the supply roll and away from a succeeding overlapped sheet interleaved with the fed sheet.

Abstract: A sheet transport includes one or more drive nips and a mechanism for automatically disengaging the nips in response to a predetermined condition such as the sensing of a jammed or stalled sheet, the movement of a sheet delivery tray between a sheet feeding position and a retracted position or the opening of an access door to the sheet transport. In a preferred form, one element of each drive nip is moved from the other element on a pivoted mounting.

Abstract: An ejector unit for machines for handling signatures and similar flat articles comprises a first rotary body defining the output end of a conveyor on which a substantially continuous flow of articles to be handled is fed, a stop member selectively orientable between a rest position and an operating position in which the member stops the flow of articles adjacent the output end of the conveyor, and two second rotary bodies which can be rotated by the first rotary body to carry out a shaping (ribbing) action on the articles handled. Third rotary bodies interposed between the first rotary body and one of the second rotary bodies are movable between a first operating position in which motion is transmitted from the first rotary body to the second rotary bodies and a second operating position in which the transmission of rotary movement between the first rotary body and the second rotary bodies is prevented.

Abstract: Method and apparatus for creating a gap in a stream of sheets, and also moving the sheets at a uniform rate onto a take-off conveyor. The function is accomplished by diverting a portion of a conveyor to have it move through a longer path than the original path, and thereby have the portion move faster in order to create the gap.

Abstract: A feed member is selectively driven and brought into contact with an image forming medium so as to feed the image forming medium stored in a storage section in a direction toward an image forming section. A drive mechanism selectively applies a force to the feed member so that the feed member is brought into contact with the medium so as to feed the medium. A controlling means supplies a first control signal to the drive mechanism in response to a medium feed instruction signal. The medium can be sufficiently fed in accordance with the first control signal. The controlling means also supplies a second control signal to the drive mechanism in response to an error processing instruction signal when an error occurs. The feed member is separated from the medium in accordance with the second control signal.

Abstract: An apparatus forms a continuous moving stream of signatures into groups separated by gaps. The apparatus includes lugs which travel along a path having an upwardly inclined portion between belts of a conveyor. The lugs lift the signatures off the conveyor while keeping them moving at conveyor speed. Once the signatures are lifted, the lugs stop. The leading signature lifted by a lug is pinched between the lug and biasing members pressing down on the stream of signatures. A guide extends upstream from the biasing members to control stack up of the signatures behind the leading signature. When a sufficient gap has been formed, the lugs accelerate and lower the signatures back onto the conveyor.

Abstract: An image forming apparatus such as a copying machine has a memory for storing a signal corresponding to the amount of movement of a paper feed roll. The paper is fed to an image forming station and a controller is provided for moving the paper feed roll to a predetermined rotation position when the operation of the apparatus is suspended by detection of a jam.

Abstract: A sheet distribution method is provided which, when a stop switch (20) to stop a copying operation of a copying machine (1) or an interrupt switch (21) to interrupt the copying operation is depressed during the copying operation in a collation mode or an assortment mode, inhibits any further copying operation while keeping only a copy sheet conveyor section operative to deliver already fed copy sheets to a collator 82). When the number of copy sheets stored in the collator (2) has coincided with the number of fresh sheets fed out of the copying machine (1) during that copying operation, the conveyor section is made inoperative and the next copy start and variation in the operating mode of the machine (1) or preset number of sheet to be copied are permitted.

This machine is provided with a manual paper feed inhibiting device operable in such a manner the manual feed of the copying paper through the manual feed mouth is permitted only when and after the heat fixing device has attained the predetermined high temperature.

Abstract: A sheet stacking method and apparatus having conveyor belts for feeding overlapping cut sheets of cardboard in a flow to a stacking station, in which in order to form a gap in the flow a second conveyor belt is driven faster than a first conveyor belt and, during the time the second belt is driven at the faster rate, a third conveyor belt lifts the sheets off the second belt and drives them at the same speed as the first conveyor belt until the sheet downstream of the gap has left the second belt, whereupon the second belt is again driven at the same speed as the first belt and the third belt replaces the flow of sheets onto the second belt.

Abstract: A feed assembly for feeding sheets seriatim from a position of register on a feed table to an impression cylinder in a printing press which includes a pre-gripper having an oscillating connection with the press drive for periodically swinging the pre-gripper from a sheet pick-up position at the front edge of the table to a sheet-releasing position at the surface of the impression cylinder. The pre-gripper has a jaw and a jaw lever for opening and closing the jaw. A gripper operating cam is arranged in the path of movement of the jaw lever as the pre-gripper oscillates back and forth, the oeprating cam being mounted for retreating and return movement to control the opening and closing movement of the jaw. A rotating control cam coupled to the press drive has a control cam follower with a linkage for connecting the same to the gripper operating cam for controlling its retreating and return movement so that the jaw is closed upon an awaiting sheet at the pick-up position.

Abstract: A cam operated document stop in an item sorter provides positive action to halt the passage of a document or other item, from a flow of documents in a mainstream pathway, when it arrives in an inspection station. The document is stopped in an open receptacle area for inspection and then released for return to the mainstream pathway. Stoppage is effected by rotation of cam members which position a stop arm to stop the flow of the document. After the document has been inspected and corrected, the stop arm is repositioned to release the document into the mainstream flow. After a suitable delay to allow the document to clear the receptacle area, the cam members rotate the stop arm into position to stop the next document.

Abstract: A product grouping station in a system for offloading bacon strips or the like comprises hydraulically-actuated lifters which lift groups of the bacon strips clear of the unidirectionally driven conveyor as they proceed away from the transfer station, and then release the groups in time sequence to achieve separation on the conveyor. The product grouping station is particularly adapted to handling thin strip-like products such as bacon slices, and employ novel control circuitry to obtain a continuous uniform operation for the offloading system which does not interfere with the operation of the continuously moving conveyor belt.

The mounting and cartridge are keyed to detect that a cartridge containing a predetermined denomination is properly mounted with the issue slot open to enable the drive mechanisms. A sensor is provided to detect a cash out condition to inhibit operation of the drives.

Abstract: In an electrostatic reproduction machine there is provided one or more rollers capable of rotating in union with a copy sheet being advanced, in the course of travel of the copy sheet. Sensing switches are provided for sensing nonuniformity in rotation of the rollers which may occur in abnormal copy sheet transportation states and, more particularly, in a jam state. The outputs from the sensing switches are utilized for identifying the abnormal machine states.

Abstract: In a bottle labeller of the type having a rotating discharge roller with an extending finger that withdraws a label from a magazine, the discharge roller contains a piston in which the finger is carried by a complimentary shape of a slot in the piston with the base of the finger. The piston moves in a cylindrical bore both axially and rotatably to retract the finger from extended position into the roller when a bottle detecting system discovers an interruption in the flow of bottles to the labeller. The detecting system directs pressurized air to the roller, forcing the piston to move in the bore and retract the finger when an interruption is discovered.

Abstract: From a printing machine a stream of printing products is received. To build up a stack of predetermined length a plurality of part-stacks is successively composed from the incoming stream. Each of the part-stacks comprises at least one product. The total number of products within the plurality of part-stacks is adjusted so as to correspond to the predetermined length of the stack to be built up. If said plurality of part-stacks having said total number has been successively composed these part-stacks are combined to form the total stack having the predetermined stack length.

Abstract: A sheet feed apparatus feeds sheets, placed on a sheet receptacle, one by one toward a sheet processor. When the sheets on the receptacle are exhausted, the operation of the apparatus is interrupted by a signal from a signal emitter which operates to detect the termination of sheet delivery. The signal emitter is actuated upon the detection of the occurrence of a plurality of idling operations of the sheet feed apparatus.
