  • the principle object of this invention is to provide for the separation of returned documents from those in the stack yet to be copied by a separator bar, and the automatic removal of the separator bar from the bottom of the stack and the positioning thereof on the top of the stack.
  • This invention relates to a document transport system comprising, in combination, 'means for holding a stack of documents to be transported, processed and returned; means for separating returned documents from those in the stack yet to be processed; a drive linkage for the separating means, comprising a rotary drive crank; a link pivotally connected to the crank, the separating means being connected to the link at a point remote from the crank; a pivot arm having one end pivot ally connected to a fixed point and its other end pivotally connected to the link at a point intermediate the crank connection and the separating means connection, whereby rotation of the drive crank one revolution causes the separating means to traverse a circumambient path out from under a stack of documents in the holding means and then over the stack to the top thereof.
  • FIG. 1 is a side view in cross section showing a document handler incorporating the improved document transport belt of the present invention in operative association with a document copying machine;
  • FIG. 2 is an isometric view of the document handler shown in FIG. 1;
  • FIG. 3 is an isometric view showing details of the document separating bail
  • FIG. 4 is an isometric view showing the drive details for the main document transports of the document handler shown in FIG. 1;
  • FIG. 5 is an isometric view showing the drive details for the return document transports of the document handler shown in FIG. 1;
  • FIG. 6 is a control schematic for the document handler shown in FIG. 1;
  • FIG. 7a-e depict a stepwisesequence of the cyclic operation of a separator bar or bail bar and its drive linkage in moving from the bottom of a document stack to the top thereof.
  • Document handler 10 incorporating the platen transport of the present invention.
  • Document handler 10 may be used with any suitable document processing apparatus, such as a copying or reproduction machine 5, which has a platen 6 on which the document to be copied rests.
  • Document handling apparatus 10 includes a supply tray 12 for storing both documents 7 to be copied and documents 8 already copied. From tray 12, one document at a time is advanced from the bottom of supply 7 by an intermittently operated primary feed roll 14 into the nip of retard roll pair 16, 17. The lower roll 16 is driven in a document feeding direction while the upper roll 17 is driven in the reverse or document reject direction (as shown by the dotted line arrow in FIG. 1) through a suitable slip coupling which normally enables the lower roll 16 to override the reverse drive input to roll 17 and thereby turn roll 17 in the document feeding direction. However, if two or more documents enter the nip of roll pair l6, 17, the reduced friction between the overlapping documents reduces the frictional drive force between roll pair 16, 17, permitting the slip clutch to engage and drive roll 17 in the reverse, document rejecting direction.
  • Transport 20 which preferably comprises a belt-type conveyor, first carries the document forward onto platen 6 until the entire document is positioned thereon. Transport 20 is then reversed to bring the document trailing edge against register 22. Register 22 locates the document in copying position following which the copy or copies are made by the copying apparatus 5.
  • platen transport 20 is again started in reverse to move the document backwards off platen 6, register edge 22 being previously retracted for this purpose.
  • Deflector 21 which was previously lowered, guides the returning document upwardly into the nip of return roll pair 23.
  • Roll pair 23 move the document along suitable return guides 26 through second and third return roll pairs 27, 28 re spectively, and back into tray 12.
  • Bail 32 is disposed substantially opposite to and above primary feed roll 14 to prevent documents resting thereon from contacting roll 14. As will appear, bail 32 may be reset onto the top of the documents in tray 12 when it is desired to refeed the documents to copying machine 5.
  • document tray 12 includes a substantially flat downwardly inclined base 31 and suitable supporting frame 36 carried on copying machine 5 adjacent platen 6.
  • a curved guide 33 leads from base 31 to platen 6, which in the arrangement shown is substantially horizontal.
  • a series of openings 29 in both base 31 and guide 33 accommodate rolls 14, 16 and 18.
  • a tray assembly 30 is provided A for holding the documents, the tray assembly being comprised of matching right and left hand receptacles 41, 41 respectively.
  • Receptacles 41, 41' are arranged in facing relationship to one another and supported by their lower ends on shaft 42, the receptacle supporting segment of which is rectangular in cross section.
  • Shaft 42 is journaled for rotation in bushings 43 on frame 36 adjacent the bottom of base 31.
  • Shaft 42 carries stop collars 44 at each end between bushings 43 and cover supports 45, the latter serving to support tray cover from shaft 42 as will appear.
  • Cover supports 45 each include a drive lug 45' adapted, following predetermined rotation of the cover 60 in the opening direction to engage a mating shoulder 44' on the adjoining collar 44 and thereby drivingly couple shaft 42 and receptacles '41, 41' thereto.
  • Receptacles 41, 41 each include a base 46 and outer side 47.
  • the upper portion 47' of receptacle sides 47 are preferably flared outwardly to provide a slightly enlarged entrance facilitating entry of returning documents to the tray assembly 30.
  • the relative narrower sides 47 therebelow aid in aligning the document side edges with one another.
  • Receptacles 41, 41' are preferably supported for lateral adjusting movement along the rectangular portion of shaft 42 toward and away from one another to accommodate various size documents.
  • the receptacles 41, 41 are interconnected adjacent their lower end by means of cord 48.
  • Cord 48 is supported around pulleys 49 with one terminal end thereof secured to one tray 41 and the other to tray 41 As can be understood, movement of cord 48 effects simultaneous movement of trays 41, 41 toward or away from one another.
  • Suitable detent means may be provided to maintain the receptacles 41, 41' in pre-selected positions corresponding to conventional document widths.
  • Torsion springs 50 bias receptacles 41, 41' inwardly toward base 31 (in the clockwise direction as seen in FIG. 1), it being understood that contact between base 31 and the bottom 46 of receptacles 41, 41 limits inward movement of receptacles 41, 41'.
  • cover 60 is provided to guide returning documents into the receptacles 41, 41' as well as prevent documents from falling out of the receptacles 41, 41, particularly when bail 32 is reset. As described, cover 60 is rotatably supported from shaft 42 via supports 45 which enable the cover 60 to be swung open for access to the tray assembly 30 during loading and unloading of documents.
  • Cover 60 includes an exterior wall 62, which may be suitably decorated, depending sides 63, and interior wall 64, which together form a hollow section or plenum 65. As may be seen in FIG. 2, cover 60 is substantially rectangular in shape, and sized to overlay the entire base 31 including the tray assembly 30. Interior wall 64 of cover 60 is substantially flush with the top edge of receptacle sides 47 when cover 60 is closed, the wall 64 serving as a guide to help route returning documents into receptacles 41, 41' as will appear.
  • a fan 66 is disposed within the cover plenum 65 opposite outlet 67 in interior wall 64.
  • Fan 66 serves to discharge a low pressure stream of air downwardly through outlet 67 onto the documents therebelow in tray assembly 30.
  • Fan motor 68 is housed in the cover plenum 65 and suitable air inlet openings (not shown) are provided in the cover proper for fan 66.
  • Cover 60 carries a depending detent and stop member 70 on each side thereof, stop members 70 being slotted at 71 to receive guide pins 72 supported from each side of the frame 36.
  • the bail 32 is carried by arms 81 which are in turn pinned to intermediate links 82.
  • Each link 82 is pivotally supported on the frame 36 through an arm 83.
  • Upstanding frame brackets 36' are provided for this purpose, arm 83 being in effect pinned between brackets 36' and link 82.
  • Intermediate links 82 are also pinned to crank arms 84 carried by the transversely extending output shaft 85 of a one revolution clutch 180. As will appear more fully herein, engagement of clutch 180 turns shaft 85 and crank arms 84 through one revolution.
  • bail 32 On rotation of crank arms 84, and due to the interrelationship of links 82 relative to supporting arms 82, 83, bail 32 moves through a generally rectangular path, initially in a forward direction generally parallel to tray base 31, then up away from base 31, then back toward primary feed roll 14, and then down toward base 31.
  • bail 32 With reference to any documents in tray 12 which rest on bail 32, bail 32 moves first forward out from under the documents, then raises up to a position above the documents, then moves back to a position above feed roll 14, and then down onto the topmost document.
  • springs 86 are provided to bias arms 81 in a downward direction toward tray base 31.
  • a photocell type detector 88 is provided on bail 32.
  • a light 89 for detector 88 is located under base 31 and opposite detector 88, base 31 being suitably apertured for this purpose. As will appear, detector 89 responds in certain circumstances to the absence of documents under bail 32 to actuate clutch 180 and reset the ball 32 as described heretofore.
  • a suitable ion generator 92 is provided adjacent the entrance to the document tray assembly 30.
  • Generator 92 which is connected to a suitable source of electrical energy (not shown), serves to ionize the air through which the documents returning to tray assembly 30 pass to help neutralize any static electric charges that may be on the documents.
  • Motor 100 may be conveniently supported on frame 36 below tray base 31.
  • Motor shaft 101 is connected by means of toothed belt 102 with main power takeoff shaft 103.
  • the primary feedroll l4, retard roll pair 16, 17, and lower roll 18 of intermediate roll pair 17, 18 are preferably operated at a lower speed than that of platen belt 20 and return roll pairs 23, 27, 28.
  • a toothed belt 104 drivingly connects shaft 103 with clutch 105 on transfer shaft 106.
  • clutch 105 when actuated, couples power takeoff shaft 103 with transfer shaft 106.
  • Transfer shaft 106 which is suitably joumaled in frame 36, carries a drive pulley 108 on the outside end thereof.
  • a toothed belt 109 drivingly connects pulley 108 with gear 110 on shaft 111 of the bottom limiting roll 16 and with toothed pulley 112 of overrunning clutch 114.
  • Clutch 1 14 is supported on shaft 115 of the bottom intermediate transport roll 18 and serves to turn shaft 115 in a document feeding direction unless the high speed drive input to shaft 115 is operational,
  • Primary feed roll 14 is supported by shaft 118 which in turn is suitably joumaled in frame 36.
  • Drive belt 117 drivingly connects shaft 118 with limiting roll support shaft 1 1 1.
  • actuation of clutch 105 drives primary feed roll 14, lower retard roll 16, and lower intermediate transport roll 18 at low speed in a document feeding direction.
  • power takeoff shaft 103 carries a drive pulley 120 on the terminal end thereof.
  • Pulley 120 is connected with pulley 121 on stub shaft 122.
  • Gear 123 on pulley 121 meshes with gear 124 on shaft 125 supporting the lower rolls of return transport roll pair 28.
  • a toothed belt 126 drivingly connects shaft 125 with shaft 127 supporting the lower rolls of return transport pair 27.
  • a second belt 128 drivingly interconnects shaft 125 with shaft 130 supporting the lower rolls of return transport pair 23.

  • Shaft 137 of clutch 136 is suitably joumaled in transport subframe 36".
  • Gear set 138 drivingly couples clutch shaft 137 with the retard roll 17.
  • engagement of clutch 136 drivingly couples clutch shaft 137 with driven shaft 125 to turn retard roll 17 via gearset 138 in the reverse or document rejecting direction (shown by dotted arrow in FIG. 6).
  • Hysteresis clutch 136 is preset to engage whenever the reverse torque applied to shaft 137 generated through contact of roll 16 with retard roll 17, either directly or through the intermediary of one or more documents therebetween, falls below a predetermined level. This normally occurs whenever more than one document at a time attempts to pass between the retard roll pair l6, 17. At other times, clutch 136 is effectively disengaged and retard roll 17 turns with roll 16 in the document feeding direction.
  • a double clutch 140 is provided on an intermediate transfer shaft 142.
  • one side of clutch 140 carries a forward drive gear coupled to power take off shaft 103 by means of gear 148.
  • the other side of clutch 140 carries reverse drive pulley 143 coupled to shaft 103 via toothed belt 144.
  • Output pulley on shaft 142 is drivingly coupled by toothed belt 151 with idler gear 152 on stub shaft 153.
  • a second pulley 154 on shaft 153 is coupled by toothed belt 155 with pulley 156 on shaft 157 of platen transport roll 231.
  • Gear 158 on stub shaft 153 meshes with gear 159 of one-way clutch 160 on shaft 115 of lower intermediate transport roll 18.
  • One-way clutch 160 functions to drivingly connect shaft 115 and lower intermediate transport rolls 16 with transfer shaft 142 whenever clutch 140 is engaged in the forward document feeding direction to provide high speed drive to roll pair 18, 19. On engagement of clutch 140 in the reverse feeding direction, clutch 160 disengages to prevent reverse rotation of intermediate transport roll pair 18, 19.
  • the upper intermediate transfer roll 19 is supported on idler shaft 161 suitably joumaled in frame 36.
  • overrunning clutch 114 additionally serves to accommodate overruning of roll 18 when both clutches 105 and 140 are simultaneously engaged.
  • high speed drive from motor 100 is conducted by clutch 140 in either the forward or reverse direction to platen transport 20. Where clutch 140 is engaged in the forward direction, intermediate feed roll pair 18, 19 are turned at high speed.
  • Bail clutch has an input gear 183 drivingly connected by belt 184 with stub shaft 186.
  • Gear 187 on shaft 186 is driven from reverse drive gear 145 through suitable intermediate gears (not shown) designed to drive belt 184 at the proper speed and in the proper direction.
  • Clutch 180 comprises a suitable solenoid actuated one revolution clutch effective when engaged to turn crank arms 84 through one revolution and thereby reset bail 32.
  • controller 301 includes a suitable timing or counting device (not shown) driven by means of clock disc 302 on power transfer shaft 103, there being a suitable signal generator here shown as photocell 304, and light source 305 disposed on opposite sides of disc 302. Note FIG. 4. Apertures 303 in disc 302 permit light from light source 305 to intermittently strike photocell 304 as disc 302 rotates to provide a clocklike input pulse.
  • Starting and stopping of document handler motor 100 may be conveniently effected by means of a suitable manually operated start-stop control 308.
  • operation of the document handler 10 is dependent upon enabling signals from copying machine 5, tray cover safety switch 80 and platen transport safety switch 309, respectively.
  • Switches 80, 309 reflect disposition of tray cover 60 and platen transport 20 in their closed operating positions. It is understood that other contingency controls may be provided.
  • the documents 7 to be copied are placed in tray assembly 30 trailing edge down, the document or docu- 7 ments resting atop bail 32. It is understood that receptacles 41, 41 are adjusted for proper document size.
  • stop-start control 308 actuated and platen transport 20 lowered, closing cover 60 starts document handler motor 100. It is understood that return transport roll pairs 23, 27, 28, whichare directly coupled to motor 100, are driven whenever motor 100 is energized.
  • controller 301 engages bail clutch 180 to move bail 32 through one cycle from a position below the documents in tray 12 to a position on top of the documents in the manner explained heretofore.
  • controller 301 in response to the document demand signal of wait station detector 312 at the entrance to platen 6, actuates clutch 105 to drivingly couple primary feed roll 14, retard roll pair 16, 17 and intermediate feed roll pair 18, 19 with motor 100. Rotation of feed roll 14 advances the bottommost document in tray 12forward through retard roll pair l6, 17
  • controller 301 actuates clutch 140 to couple gear 145 to drive shaft 142 and thereby operate intermediate feed roll pair 18, 19 and platen transport 20 in the forward direction to advance the waiting document onto platen 6. It is understood that engagement of clutch 140 in the document forward feed direction drives intermediate feed roll pair 18, 19 at high speed, overrunning clutch 114 accommodating the difference in driving input speed in the event primary feed clutch 140 is engaged.
  • controller 301 switches clutch 140 from forward to reverse drive, the latter coupling drive pulley 143 with shaft 142.
  • Platen transport 20 is therefore reversed and the document moved backwards on platen 6 until the rear or trailing edge thereof abuts against register 22. Abutment of the document edge with the edge of register 22 locates the document in predetermined copying position. With document movement prevented by register 22, belt 20 slides across the document surface until clutch 140 is disengaged. It is understood that one-way clutch 160 prevents reversing of intermediate feed roll pair 18, 19 upon reversing of platen transport 20.
  • Platen transport 20 is operated in reverse by controller 301 for an interval sufficient to allow transport 20 to bring the document trailing edge against register 22, at which point clutch 140 is disengaged and platen transport 20 stopped. With the document in copying position, copying apparatus is then enabled to begin the copying cycle.
  • controller 301 again engages clutch 105 in response to the demand signal from detector 312. Rolls 14; 16, 17; and 18, 19 are therefore operated to bring the next or second document forward as explained heretofore.
  • controller 301 disengages clutch 105 to prevent feeding of another document. At this point therefore, the first document is in copying position on platen 6 while the second document is in a waiting position adjoining the inlet to platen 6.
  • controller 301 actuates register drive clutch 170 to retract register 22 and lower deflector 21.
  • controller 30 actuates clutch in the reverse drive mode to couple belt 144 with shaft 142.
  • Platen transport 20 is therefore driven in reverse to move the document off platen 6.
  • deflector 21 routes the document into the nip of first return transport roll pair 23.
  • Roll pair 23 cooperate with return guides 26 and roll pairs 27, 28 to carry the document back to tray 12 where the document is deposited into receptacles 41, 41 atop bail 32.
  • controller 301 actuates register drive clutch to bring register 22 forward 'to registering position on platen 6.
