Definitions

  • This invention relates to a finishing apparatus for receiving and binding into sets precollated copy sheets from a document reproducing apparatus, comprising a compiling station for registering and assembling copy sheets into sets and at least one stapling device for binding a set compiled at the compiling station and having means for clamping an edge of the set during stapling. It also relates to a document reproduction system incorporating such a finishing apparatus.
  • a finishing device such as a stitcher or stapler is activated to bind the set.
  • These systems are of the precollation type wherein the document sheets are precollated in the document handling apparatus prior to commencement of a reproduction run. The output for the reproduction machine will likewise be precollated in sets corresponding to the sequenced numbered document set in the document handling apparatus. The copy sheets are collected in collated sets as they are sequentially produced so that binding may be effected without the interacton of additonal devices.
  • Such systems are described in U.S. patent No. 4,134,672.
  • the present invention contemplates the concept of utilizing a compilation station which includes the stapler or stitcher heads in order to avoid the use of copy set transport devices and permit continuous compilation of successive copy sets.
  • Present day machines on the market such as the Xerox duplication machine labeled the 9400° Duplicator marketed by Xerox Corporation of Stamford, Connecticut, utilizes a document handler as an input device which exposes as many copies of a single document sheet at a time as is appropriate - before starting on the next document sheet.
  • the present invention contemplates utilizing a recirculating type of document handling apparatus such as of the general type disclosed in the above referred to U.S. Patent No. 4,134,672. Any other suitable recirculating type of document handler may also be used in conjunction with the processor for the 9400 Duplicator.
  • a finishing apparatus is characterised in that said compiling station includes a support surface movable, while a said set is clamped by said stapling device, between a first position for supporting sheets received at the compiling station as they are being compiled into a set and a second position out of its supporting position for removing a bound set from the compiling station.
  • the compilation station is defined by a . movable, horizontally arranged plate upon which sheets are collected, and the stapling heads for one or more stapling apparatus.
  • the plate is quickly retracted from the set in timed sequence with the clamping of the stapling heads whereupon the rear edge of the set lowers to carry the set downwardly upon a set collecting, vertically movable tray.
  • a set kicker may be employed to facilitate quick removal of the stapled edge out of the stapling heads.
  • the compiling plate is repositioned into its compilation position to catch the first sheet of the succeeding copy set.
  • the collecting plate reciprocates, that is, moves from a collecting position to a retracted position and back to its collection position at a cycle rate approximately equal to the rate of production of the reproduction machine with which the finisher is associated so that there is no loss of productivity.
  • the time during which the plate reciprocates is approximately equal to the pitch time for the machine or that time for a copy sheet to move a distance from the leading edge of one copy sheet to the leading edge of a succeeding sheet regardless of where the sheets are in the system.
  • the printing system is preferably of the xerographic type as one including a xerographic processor 11, and a recirculating type document handling apparatus 12.
  • the processor 11 is the same as the processor in the commercial embodiment of the Xerox duplicator 9400 * , which utilizes flash, full frame exposure for very high speed production.
  • Document sheet exposure, image processing and copy sheet transport/handling are under control by a machine programmer and are effected in timed seqence, and in accordance with the program an operator has preset in the machine.
  • the system comprising the processor 11 and the document handling apparatus 12 is under control of a programmer P which permits an operator various options: to turn the entire system ON or OFF; to program the reproduction system for a desired number of reproductions to be made of each original document sheet or set; to select whether simplex or duplex copies are to be made; to select a desired output arrangement, that is, sets mode or stacks mode, stapled or unstapled; to select one of a plurality of paper trays; to condition the machine for the type of document, that is, whether one sided or two sided, to select a copy size reduction mode, and other desirable functions.
  • the programmer P also includes a controller which provides all operational timing and synchronization between the processor 11 and all of its xerographic processing functions, and system control functions, the automatic events to be described hereinafter.
  • the controller may include any suitable microprocessor having a CPU and the appropriate machine clock, but preferably the microprocessor is one similar to the Intel 8080 Microprocessor manufactured by the Intel Corporation, Santa Clara, California, and having sufficient ROM's and RAM's for all of the necessary functions in the reproduction system.
  • the document handling apparatus 12 serves to feed one document sheet at a time from a supply of document sheets of a document D into copying position on the platen 14 where a single exposure of each document sheet is made per document set and during sequential operation. Following exposure, each document sheet is automatically returned to the document supply and the next document sheet, if any, is brought into the exposure position on platen 14. Document sheets returned to the supply stack may be recycled by the apparatus 12 in the event additional copy sets are to be produced, or simply removed by the user when the copying program is completed.
  • copy sheets exiting through the exit slot 50 positioned at one end of the housing for the xerographic processor 11 are directed to the finishing station 13 which comprises a compiling station, a stapler apparatus, and an output elevator system.
  • the finishing station 13 which comprises a compiling station, a stapler apparatus, and an output elevator system.
  • each sheet is positioned upon a transport 92 to be further conveyed generally along the same horizontal plane as its previous path to a fixed receiving point or station 93.
  • the transport includes a movable endless transport belt 94 upon which each sheet is placed and a plurality of loosely retained rotatable balls 95 which rest on and along the belt 94 by gravity and which coact with the belt to convey sheets therebetween.
  • the belt 94 is driven by a motor and suitable gearing and pulleys (not shown) at a velocity slightly greater than the processing speed of the processor 11 in order to add more working space between the sheets and to ensure that the final handling of copy sheets does not impede the throughput of the entire system as determined by the process speed of the processor 11.
  • the rate at which the sheets arrive at the station 93 nevertheless is the same as the process speed or reproduction rate of the processor.
  • the axis of the belt 94 is at a slight angle to the direction of the movement of the copy sheets.
  • This arrangement drives each sheet of copy slightly laterally against a side registration edge 97 which is parallel to and offset from the centerline of the incoming path of sheet movement.
  • the sheet S as can be seen through a sheet clearance opening 98 formed in the top plate of the transport 92. In this orientation, the sheets are positioned so that their toner image side is down, for the simplex mode, or an odd numbered page is down for the duplex copying mode, and the top of each sheet is along the edge 97.
  • a sheet contacting switch S-1 is positioned to be actuated as each sheet enters the transport 92 of the finishing station 13.
  • the circuit for this switch is connected to the logic in the programmer P and serves to reset the machine clock for the finishing function so that zero time for the sheet commences when the sheet is at the station 93 which serves as the system reference point.
  • a pair of contacting transport rollers or a set of corrugating rollers 100 which receive each copy sheet within the nip for directing a sheet onto a compiling receiving plate 102 located at a compiling station which includes this plate.
  • the plate 102 is suitably mounted for horizontal reciprocable movement between the position showing in Figure 2 whereat copy sheets are compiled to form a set C just prior to a stapling operation to its retracted position shown in Figure 3.
  • a pneumatic cylinder 104 having an electromagnetic actuable valve 105 is suitably connected to the plate to provide very fast reciprocable movement upon logic control in the programmer P.
  • the valve 105 is energized by means of a time signal from the programmer logic to drive the plate to the collecting or compiling position of Figure 1 or to retract the plate to the position shown in Figure 3.
  • the rate at which the plate 102 makes a complete reciprocable cycle is approximately equal to the rate of production of the processor, or its pitch per unit of time. For example, if the production rate for the processor is 120 copies per minute, its pitch is one sheet plus one space between sheets per one-half second and the cycle time for reciprocation of the plate will be approximately one-half second.
  • an individually-operable, dual stapler apparatus 110 which provides a stapling function either with a single staple or with two staples, both being adapted to be applied at variable positions along the long edge of a set C of copy sheets. Stapling is achieved by way of two identical mechanisms, each of which provides the functions of copy set clamping, staple driving and staple clinching.
  • the apparatus utilizes two commercial type stapler heads 112, such as the Bostitch staple head indicated as the 64-E manufactured by the Bostitch Division of the Textron Corporation of Buffalo, Rhode Island.
  • the stapling apparatus 110 may be identical to that disclosed in detail in the commonly assigned copending application Serial No. 180,184, filed August 21, 1980.
  • logic timed control signals are imparted to two electromagnetic clutches and one solenoid in order to acquire copy set clamping along the edge of the copy set to be stapled; staple driving which separates a staple from a supply and drives it through the set; and clinching wherein the staple legs are bent to secure the copy sheets.
  • the receiving plate 102 is in the position shown in Figure 1 wherein its far edge is adjacent the clamping position for the stapling apparatus.
  • sheets are conveyed past the reference point 93 by the rollers 100, they are directed upon the plate 102 and into clamping positions relative to the stapler heads 112.
  • corner registration members 114, 115 As the sheets are being directed into their prestapling position, they engage and become registered against corner registration members 114, 115.
  • the member 114 is positioned between the heads 112 and in spatial arrangement so that when all sheets of a set are against the member, the now aligned edge of the set is in proper position to be clamped and stapled by the stapling heads.
  • a stapled copy set is dropped onto an elevator device 118 which is utilized to collect into a pile stapled or unstapled sets or stacks of copy sheets for delivery to an operator.
  • the elevator comprises a tray 119 mounted in cantilever fashion at the upper ends of a pair of vertically arranged, drive screws 120 threadedly received in threaded members 121 secured one to each side corner of the tray 119, so that upon rotation of the drive screws 126, the tray 119 is moved vertically in the up or down directions.
  • a reversible motor M-1 is operatively connected to the member 121 for imparting rotation to the same in either direction. Elevator height of piled sets or stacks is controlled by an optical sensor SR-1 which "looks" across the pile and effects the energization of the motor M-1 and lowering of the tray 119 until the pile is at or below the sensor.
  • Corresponding copy sheets are produced in collated arrangement in the processor 11 and exited at the slot 50 in succeeding order in accordance with the production rate for the processor. Since the present invention is arranged so that there will be no skipped pitches in the production run, the copy sheets will be evenly spaced throughout processing, for all twenty times five, or one hundred sheets set to be produced.
  • the first five copy sheets, corresponding to the first complete cycling of the document apparatus 12 are transported by way of the transport 92, through the reference point 93 and into the compiling station to be collected for a stapling operation. Each of these sheets is conveyed to and upon the top surface of the plate 102 and into the clamping position for the stapling heads 112, the leading edges of the sheets being registered by the devices 114, 115.
  • the clamping clutches for stapling heads are activated to clamp the adjacent edge of the collected set.
  • the compiling plate 102 is retracted to permit the lowering of the opposite or trailing edge of the set, as shown in Figure 3.
  • This plate is returned immediately to its compiling position as shown in Figure 1 so as to be in position to receive the first sheet of the second set of five copy sheets being transported.
  • the clutch for providing the force to drive staples through this edge and the clinching solenoid are activated in timed sequence to produce a stapled set.
  • the forward registration device 114 may be suitably connected to a kicker driving mechanism and timed in its actuation to kick the stapled edge out of the stapling positions of the heads 112 at the instant before the plate 102 is returned. With the far portions of the stapled set already in position below the level of the plate 102 and dropping, the final kick of the set causes immediate lowering of the set and out of the return path of the plate.
  • Final kicking of a completed copy set is such that the compiling plate 102 is returning to the compiling station as the first copy sheet of a succeeding copy set being produced.
  • the logic will determine when these actions are to occur by way of operator manipulation of the programmer P during presetting of the desired reproduction run. As the stapled sets are produced, one by one they fall upon the elevator tray 119 which lowers in accordance with the sensed height of. the topmost set thereon.
