Definitions

  • This invention relates to sheet distributing or sorting devices and more particularly to an apparatus which can continuously sort large numbers of multipaged documents as copies of a particular page proceed from a reproducing device such as a printer or copy making machine.
  • a reproducing device such as a printer or copy making machine.
  • sorters should be modular to the extent that if a module does not have the capacity, additional modular receiver bin sections may be provided. without any substantial loss of time or extra handling of the copied material. While smaller collators or sorters are mainly intended for the office market as a necessary adjunct to office copying machinery, larger sorters are more intended for the high volume commercial market and for large in-plant reproduction centers, commercial houses and printing departments. These higher volume paper handling installations may be turning out catalogs, maintenance manuals, instruction books, brochures, sales material and perhaps other items such as reports, bid specifications and other large quantity multipage publications. Those skilled in the art will appreciate the savings in labor, time and money if the output of a printing or copying center can be sorted and handled at a rate which is matched to the press and duplicating machinery production capability.
  • a continuous paper sorting machine in which the receiver with the bin is designed generally in accordance with the teachings of U.S.Patent No.3,938,801 which describes side-by-side stacks of inclined columns of paper receiving bins or shelves.
  • the receiver of this invention is moved laterally with respect to a generally upright feeding device, in which the feeder is comprised of a base section and an upstanding tower portion.
  • An in-feed conveyor is located generally midway between the top and bottom of the tower and receives sheets of paper from the press or duplicating machinery.
  • a proof tray is supported above the infeed conveyor and a deflector mechanism is provided on the infeed conveyor for directing the sheets either upwardly into the proof tray or to allow the sheets to pass on through to the feeder.
  • a deflector at the junction of the infeed and the upward and downwardly intermediate conveyors directs ehets of paper either into the upper intermediate conveyor or onto the downwardly intermediate conveyor depending upon feeder controls programming .
  • a generally vertically disposed reversible feeder conveyor extends between the outer ends of the two intermediate conveyors and receives paper from either direction.
  • the feeder has drive and clutching means for reversing the direction of movement of the feeder conveyor.
  • a series of paper deflectors are located on the feed conveyor and are designed to deflect paper copies from either direction. The deflectors are individually actuated by drive solenoids.
  • a deflector guide section is provided on a hinged frame which swings away from the conveyor to allow access to paper jams and for maintenance.
  • the deflector guide frame is mounted for pivotal movement so that the guides arc precisely located with respect to the entrances to the bins on the receiver.
  • a paper sorting machine feeder device which is continuous and uniquely designed and intended for maximizing the production volume of a commercial printing, reproducing, duplicating or copying center.
  • the invention is particularly intended to reduce and to minimize the amount of time a reproduction, printing or copying device loses due to the lack of a continuous paper copy sorting capability which is matched to copy making capacity. Because of the unique feeder in conjunction with the canted columns of bins type of receiver, there is no necessity to stop the sorting of paper copies from column to column. The machine can continue to sort as it moves from tray-to-tray and from column-to- column without interruption of copy production.
  • the receiver can be unloaded off line, so that a filled receiver may be rolled away and an empty receiver moved into position with a minimum of lost time.
  • the invention is particularly suited for use in printing shops or reproduction centers for such things as multi-pag.e brochures, catalogs, books and other items which must be produced in large numbers.
  • the machine is capable of receiving sheets and feeding them at the high speeds of present day advanced copying, printing and duplicating machinery.
  • Feeder 10 is in position between a duplicator or press device generally designated by the number 12 and a receiver mechanism generally designated by the number 14.
  • the receiver moves laterally back and forth on track structure 16.
  • Feeder 10 includes an infeed conveyor section 18, a proof tray assembly 20 and a control panel 22.
  • the infeed conveyor feeds either to a downwardly angled intermediate conveyor 26 or an upwardly angled intermediate conveyor 24.
  • a tower section generally designated by the number 28 supports a vertically disposed reversible feeder conveyor, bin deflectors and guides to be described more in detail hereinafter.
  • the tower section 28 is supported on a base section 30 shown in generally outlined form in Figure 1.
  • the infeed conveyor 20 includes side frame members 36 in which is supported a conveyor plenum enclosure 38 having an outer end 40 and inner end 42.
  • the conveyor plenum 38 has a wall 46 in which are disposed rows of openings 48.
  • the openings 48 are formed in the wall 46 so as to present transverse as well as longitudinal rows over substantially the entire length of the plenum structure 38.
  • a shaft 50 is supported adjacent the inner end 42 of the plenum and has affixed thereto a plurality of rollers 52.
  • a shaft 54 has a series of belt rollers 56.
  • a series of belts 58 extend around the rollers 52 and 56 as seen in the drawings.
  • a short section of transfer conveyor belts 60 extend around rollers 62 which are also affixed to shaft 54 to accept the sheets of paper from the press or duplicating device for transfer to the infeed conveyor 18.
  • a fan means 34 is provided in the infeed conveyor for creating vacuum or negative pressure for holding the sheets of paper on the belts 58.
  • the proof tray structure generally designated by the number 20 includes proof conveyor belts 64 which extend around pulleys 66 and 68 mounted on shafts 70 and 72 respectively.
  • the proof conveyor feeds to a tray 74 having side walls 76.
  • a proof deflector 80 is mounted on a shaft 82 and is biased into a normal position such that when power is off the deflector would be in an intercept positionwith respect to sheets of paper coming onto the infeed conveyor.
  • the proof deflector 80 is actuated by a solenoid 84 as seen in Figure 2.
  • a direction deflector 86 is provided at the inner end of the infeed conveyor structure for directing sheets of paper off the infeed conveyor either to the upwardly angled intermediate conveyor 24 or the downwardly angled intermediate conveyor 26.
  • Directional deflector 86 is'mounted on shaft 88 and is in turn selectively actuated by the solenoid 90 again shown in Figure 2.
  • the proof conveyor belts and pulleys 64, 66 and 68 are driven by a power belt 92 extending from a drive pulley 94 on shaft 54 to a pulley 96 mounted on shaft 70.
  • the infeed conveyor belts 58 in turn are driven by a belt 98 which extends around drive pulley 100 mounted on shaft 50, again as best seen in Figures 2 and 3.
  • FIG 4 directed to details of the base 30 and the feeder tower frame 28, shows base 30 to be a generally rectangular box-like structure housing motor 110 and other parts as will be more particularly described hereinafter.
  • Base 30 has a bottom wall 112, side walls 114, a rear wall 116 and top wall 118.
  • a conveyor frame receiving area is defined by a recessed wall 120 which is spaced a predetermined distance from the front wall 120, and as can be seen, angles upwardly and rearwardly generally parallel to the bottom intermediate conveyor section 26.
  • Supported within the recessed area of the frame are two spaced apart main upstanding or vertical frame members 124 and 126 seen in Figure 4 and also in Figure 8.
  • a horizontal top frame member 128 interconnects main upright frame members 124 and 126.
  • Mounting frame members 128 and 130 are secured to the main upright frame members 124 and 126, respectively, for additional frame rigidity as well as for supporting other parts.
  • an internal, triangular, inner wall structure generally designated by the number 132. It will be seen by reference to Figure 4 that the wall 132 extends from near the lower end of the uprights to a point near the upper end of the uprights. Extending generally vertically is a wall 134 which with wall 132 defines a triangular enclosed space 136 within a basic frame structure.
  • a shroud occupied by the fan 140 provides air evacuation means for the lower intermediate conveyor 26 while a fan 144 surrounded by shroud 142 provides air evacuation means for the upper intermediate conveyor 24. Note that the shrouds and fans 138, 140, 142 and 144 are part of the wall structure 132 just described.
  • shroud 146 towards the lower part of cavity 136 and shroud 148 towards the upper part of cavity 136.
  • Shrouds 146 and 148 are occupied by fans 150 and 152, respectively.
  • the air evacuation means direct the air inwardly from the direction of the conveyors and exhaust it through screened openings 154 as shown in Figure 1.
  • Lower intermediate conveyor 26 includes an elongated generally rectangular plenum wall 160 which has both transverse and longitudinal series of holes 162. At the lower end of the plenum are a series of belt conveyor pulleys 164 mounted on shaft 166. At the upper end of lower intermediate conveyor 26 are a plurality of belt pulleys 168 mounted on shaft 170. Since the sheets of paper must traverse around the lower end of intermediate conveyor 26, the radius of turn is larger as can be seen by reference to the relative difference between the lower pulleys 164 as opposed to the upper pulleys 168. A series of guide and idler pulleys 172 increase the amount of wrap of the belts 174 around rollers 164 primarily to provide clearance between other parts and belts 174.
  • a series of spaced apart guide plates 176 having aradius of curvature 178 extend along the bottom in non-interfering relationship with belts 174.
  • a plurality of individual guide or pressure rollers 180 are mounted on plates 176 to engage belts 174 as they begin to contact rollers 164.
  • a series of rollers 184 also mounted on plates 176 engage the belts 174 to assist in the positive movement of sheets of paper around the lower end of the intermediate conveyor as the belts leave contact with rollers 164. In this way, paper sheets move positively around the end of the intermediate conveyor to be engaged by the feed conveyor 28 to be described hereinafter.
  • upper intermediate conveyor 24 has larger diameter upper belt pulleys 190 mounted on shaft 192 with pressure or paper guide rollers 194 and 196.
  • Lower end pulleys 198 are mounted on shaft 200 with the upper end shaft 192 and the lower end shaft 200 being mounted at the ends of plenum wall 202 having transverse and longitudinal rows of openings 204.
  • Belts 206 extend around the upper and lower pulleys again with idler or wrap-around pulley assembly 208 serving the same function as pulleys 172 at the lower end of the lower intermediate conveyor.
  • guide plates 210 having a radius of curvature 212 allow a sheet of paper to traverse around the top end of the conveyor to the vertical feed conveyor. It is to be observed that the pressure or retainer rollers 196 and 194 could be mounted individually on the guide plates as shown or on a common shaft or bar extending laterally across.
  • the feeder conveyor section 28 has side frame members 220 and 222 which attach to and extend between the vertical mounting pieces 129 and 130 as seen in Figure 8.
  • a series of belts 232 extend around the upper and lower pulleys 224 and 228 and idler or guide roller assemblies with pulleys 234 are mounted at spaced intervals between the upper and lower end pulley assemblies as seen in Figures 8 and 9.
  • a series of deflectors numbering 51 in total are spaced between the frame members 220 and 222, said deflectors being generally designated by the number 240.
  • the deflectors 240 are made of light aluminum sheet and are formed with a front wall 242 which when in retracted position is generally parallel to and as can be seen, slightly rearward of the carrying or paper contact surface of the belts so that the front walls of the deflectors in retracted position do not interfere with the movement of paper with the belts.
  • the deflectors are also formed with a top wall 244 which is generally at right angles and extending rearwardly from the front face 242 to define deflector edges 243.
  • the front faces 242 are provided with openings 246 extending rearwardly on the topwall 244 in the form of opening 248, as best seen in Figures 8 and 9.
  • each of the 51 deflectors is provided with a depending actuating tab 252 engaged by solenoid 254.
  • light compression springs 256 are disposed between the tabs 252 and the solenoids 256 so that the deflectors are normally biased into their retracted position as seen in Figure 4.
  • the deflectors Upon energization of the solenoid the deflectors are pivoted outwardly around the ears 250 to move the deflectors into an intercept or deflecting position with respect to pieces of paper moving either downwardly or upwardly or belts 232.
  • the edge 243 formed by the intersection of the front face 242 and the top wall 244 of the deflectors is extended outwardly so that the front surface 242 and top surface 244 are each at approximately a 45° angle to the belts.
  • Figures 4, 8 and 10 show details of the deflector guide assembly generally designated by the number 260 which include side frame members 262 and 264 with one side 264 being provided with a hinge 266 for swinging the deflector guide assembly away from the face of the feed conveyor.
  • Extending horizontally between the side frame members 262 and 264 are the generally Y-shaped guide deflectors indicated by the number 268.
  • the guide deflectors have a horizontal outer section 270 and an upwardly angled inner arm 272 and a downwardly angled inner arm 274. It will be noted by reference to Figure 4 that the outer end of the horizontal section 270 of the deflector guides terminates approximately midway between the openings to bins in the receiver.
  • the edge 243 is approximately midway between the lower angled arm 274 and the upper angled arm 272 of adjacent deflector guides.
  • a sheet of paper coming from the top of the feeder conveyor will be deflected into a given bin address by one deflector and if approaching its bin address from the bottom of the feed conveyor will be deflected into the same address by the next lower deflector. Since there are 50 bins in the receiver and 50 guide deflectors 268, it is necessary that there be 51 deflectors in order to properly address sheets of paper into the available bins.
  • An opening 276 extends all the way from the top to the bottom of the deflector guide assembly 268 to accommodate the light and photocell components 280 and 282 as seen at the bottom and top of the feeder conveyor tower in Figure 4.
  • a clutching and drive assembly is shown diagrammatically in Figure 7 and includes motor 110 and a drive pulley 111.
  • the drive pulley drives belt 113 which in turn drives pulley 115 on shaft 166 at the bottom of lower intermediate conveyor assembly 26.
  • a belt 98 also seen in Figure 2
  • a belt 92 at the outer end of the infeed conveyor drives the proof conveyor belts.
  • the motor 110 drives all of the conveyor sections of the feeder.
  • two clutch assemblies 117 and 119 are driven by a belt 121 through a lower pulley 123 and an upper pulley 125.
  • a reversing drive belt 127 connects drive power to lower shaft 230 of the reversible feed conveyor through pulley 231.
  • clutch 117 When clutch 117 is engaged, the feeder conveyor is moved to transport paper upwardly from the bottom.
  • the lower clutch 119 When the lower clutch 119 is engaged, the feeder conveyor will transport paper from the top down.
  • a horizontally disposed contact roller 290 near the top and a horizontal roller 292 near the bottom are supported on the feeder to engage the receiver 14 as it moves laterally by the feeder to prevent contact and to maintain a predetermined distance relationship between receiver and feeder.
  • tile feeder and receiver Operation of tile feeder and receiver is contindous and is best described as follows.
  • a first or page "1" master is inserted in the press or duplicator. Several copies are first directed to the proof tray and then the sorting job begins. Odd numbered pages coming out of the press are directed to lower intermediate conveyor 26 and up the feeder conveyor to the top bin. Sheets will be fed up the conveyor 232 and deflected to the desired bin address by a deflector and the lower surface of a Y-shaped deflector.
  • the receiver moves a discrete distance from left to right and presents the next bin address until all 50 bins in a column have been filled.
  • the sorting job extends to the next column copies continue to be fed to the feeder conveyor via lower intermediate conveyor 26 and up the feeder conveyor to the topmost bin in the second column.
  • the topmost bin of the second column is offset from the lowermost bin of the first column by the same increment of distance as the bins are offset from each other in each column.
  • the feeder continues to feed around the lower intermediate conveyor until all fifty bins in the second column are filled.
  • the feeder belts 232 are reversed to bring the first sheet from the top to the bottom of the feeder conveyor and filling of the bins with copies of page 2 begins with the lowest bin in column 2 where the first page sorting job ended.
  • the feeding of bins is continuous not only from bin to bin but from column to column.
  • odd numbered pages from the duplicator are fed from the bottom up while the receiver indexes from left to right and even numbered pages are fed from the top down while the receiver moves from right to left.
  • two adjacent deflectors are needed for a single bin address. When coming down the conveyor sheets are deflected by the top one of two adjacent deflectors and directed against the top surface of a deflector guide and into the bin opening. When coming from the bottom the sheet is deflected by the lower one of two adjacent deflectors and off the lower surface of a deflector into the same bin address.
