Definitions

  • the disclosed apparatus is a folding machine for FOR FOLDING MACHINES paper sheets which includes a paperworkmg assembly for per- 13 Claims, 3 Drawing Figs forming operations such as perforating, scormg or sllttmg on each folded sheet. Sheets are fed through the apparatus and U-S.
  • folded means of buckle chutes then pass through the 83/302, 83/322, 83/348, 33/430, 83/481, 83/482 paperworking assembly which comprises a pair of rotatable ll!!- hafts carrying elected combinations of cooperating pairs of Fleld ofSearch feed and working rollers which act to perforate score and/or 302, 348, 430, 563, 564, 482, 481, 503, 506, slit the folded sheets.
  • the shafts and their rolls may be moved 322 between an operative position and an inoperative position by 56] References Cited actuation of a cam which lifts one shaft.
  • This invention relates generally to folding machines and more particularly to a device for perforating, scoring or slitting folded sheets of paper as they emerge from the folding machine.
  • Paper folding machines are well known in the paper handling art and have enjoyed substantial commercial success. In general, these machines successively feed sheets of paper of various sizes from a stack into and through a folding mechanism and then discharge the folded sheets in a suitably stacked arrangement. The machines may be adjusted to make various fold configurations such as letter fold, accordion fold or single fold. The thus folded sheets are then generally delivered to some form of stacking tray or feeder in staggered relationship ready to be inserted into envelopes,although in some instances the folding machines may be attached to or otherwise associated with other paper handling apparatus, for example, an envelope stuffing machine.
  • the other types of operations which the folding machine itself is not capable for performing must be performed on the sheets subsequent to folding.
  • Another example might be where a memorandum or notice isprinted twice on the same sheet of paper for convenience in printing; in such a case it is often desirable to slit the sheet of paper between the two printed portions after the folding operation.
  • a further example arises where it becomes necessary to pass a folded sheet through the folding machine more than once in order to achieve further folding and size reduction. In this situation it has been found that if each folded sheet is initially scored along the desired fold lines, a more uniform and uncrimped fold is obtained with less jamming of the folded sheets during the subsequent folding operations.
  • an object of the present invention is to provide an improved cam actuated device for perforating, scoring or slitting folded sheets in conjunction with a sheet folding machine.
  • Another object of the present invention is to provide a device of the above character which may be readily shifted from an operative position to an inoperative position without being removed from the folding machine or pivoted from its normal plane of operation.
  • a further object of the present invention is to provide a device of the above character which does not require connection or disconnection from the drive mechanism of the folding machine when it is shifted from operative to inoperative positions.
  • Another object of the present invention is to provide a .device of the above character which is simply constructed
  • a paperworking assembly for perforating, scoring and/or slitting folded paper sheets is integrated into a paper folding machine.
  • the paperworking assembly is rendered operative and inoperative without removal or displacement from its normal plane of operation, and without disconnection from the folding machine power source. This makes the invention particularly suited for use in larger and heavier folding machines, and in those applications where frequent shifts of the paperworking assembly between operative and inoperative conditions may be required.
  • the paperworking assembly comprises a pair of rotatable shafts carrying corresponding pairs of feeding and working rollers for performing one or more of the operations of perforating, scoring or slitting folded sheets.
  • One shaft is fixed in place in the folding machine and connected to the power source.
  • the other shaft is mounted to a subframe which may be moved away from the fixed shaft to separate the pairs'of feeding and working rollers and render them inoperative.
  • the subframe is moved through rotation of a cam which bears against a portion of the subframe to lift it away from the fixed shaft, and which supports the subframe and its associated shafts in this inoperative position.
  • the paperworking assembly may be pivoted out of the machine for purposes of changing shafts, or of adding, subtracting or realigning the feeding and working rollers for various paperworking operations.
  • the paperworking assembly is provided at the discharge end of the folding machine so that after paper sheets have been folded therein, they are fed between the shafts of the assembly where they are either subject to the action of the working rollers if in an operative position, or pass through without change if in an inoperative position.
  • FIG. 1 is a side elevation sectional view of the apparatus of the invention taken along line 1-1 of FIG. 2 and showing the paperworking assembly of the invention in a normal operative position (solid lines), and pivoted from the paper folding machine for adjustment (dotted lines).
  • FIG. 2 is a front elevational view of the apparatus of FIG. 1, partly broken away to reveal the means for moving the paperworking assembly between operative and inoperative position.
  • FIG. 3 is a sectional view taken along line 3-3 of FIG. 2.
  • the folding machine comprises a pair of parallel upstanding sideplates 12 and 14 which define a frame for supporting the folding machine components.
  • Tray 16 is disposed in suitable angled relationship to facilitate the feeding of sheets seriatim by a feed roller 13 mounted on a shaft 20 which is rotatably mounted by journals 22 to the folding machine frame.
  • Roller 18 cooperates with a paper separator roll 24 on assembly 15 to insure that only a single sheet is fed at one time.
  • a slot 26 is provided in paper tray 16 through which separator roll 24 contacts the lower surface of successive sheets of paper.
  • a pair of guide surfaces 28a and 28b (FIG. 1) on guide members 30a and 30b (FIG. 2) at either side of the machine define a forward wall for the paper tray compartment of the folding machine.
  • Guide surfaces 28a and 23b together with the forward end 32 of paper tray 16 define in passageway 34 for the sheets of paper to be folded.
  • Guide surfaces 28a and 28b terminate in turn-around guides 36a and 36b (FIG. 1) for directing sheets of paper into the nip between a feed roller 38 mounted on a shaft 40, and another feed roller 42 mounted on a shaft 44 disposed in spaced parallel relationship with shaft 40.
  • the paper sheets are held against roller 38 as they round it by a guide roller 37 (FIG. 1) supported on a shaft 39 joumaled to guide members 30a and 30b (FIG. 2).
  • Buckle chute 48 may be of any desired or known construction for the purposes of this n invention; for illustration purposes, however, it is shown as comprising a pair of closely spaced parallel plates 50 and 51 having between them an adjustable stop element 49. Stop element 49 provides an abutment which stops the movement of each sheet of paper moving through buckle chute 48. This causes the sheet to buckle for folding as is more fully described hereinafter.
  • a further feed roller 52 is mounted on shaft 54 in position to cooperate with feed roller 42. Rollers 42 and 52 form a first fold as each buckled sheet of paper feeds between them; they then feed the folded leading edge of the paper sheet to the inlet end 55 of a second buckle chute 56 located beneath buckle chute 48.
  • Buckle chute 56 may also be of any desired or known construction and again for illustrative purposes is shown as comprising a pair of closely spaced parallel plates 58 and 59.
  • An adjustable stop 57 is located between plates 58 and 59 against which the previously folded leading edge of the paper sheet abuts. This stops the movement thereof and causes the sheet to buckle again to prepare for a subsequent fold. It will be seen that both buckle chutes 48 and 56 are provided with shaped guide surfaces adjacent their inlet ends for assisting the sheets of paper to buckle in the right direction, and for guiding the buckled portion of each sheet toward the next set of folding rollers.
  • a further feed roller 60 is mounted on a shaft 62 in position to cooperate with roller 42 to impart a second fold to each buckled sheet of paper as it passes therebetween, and to feed each sheet out of the folding machine.
  • guide surfaces 28a and 28b, 36a and 36b, and rollers 37, 38, 42, 52 and 60 all constitute a feeding and folding roller assembly mounted on the folding machine. It can also be seen from FIG. 1, that the nip of rollers 42 and 60 and a plane extending substantially parallel therefrom define for at least a short distance a discharge path for folded sheets of paper emerging from the feeding and folding roller assembly.
  • the folded sheets which are being discharged at a substantially high rate of speed are collected on a suitable tray or powered stacker mechanism, an example of the latter being shown in FIG. 1 wherein an endless belt 64 passes around a driven roller support 66 and an idler support (not shown).
  • the upper reach 68 of belt 64 receives the discharged folded sheets and enables them to be stacked in staggered relationship in a manner well known in the art.
  • roller 18 in cooperation with separator roll 24 and guide surfaces 28a and 28b, feeds the topmost sheet into passageway 34 and around guides 36a and 36b until the sheet is picked up in the nip of rollers 38 and 42.
  • These rollers feed the sheet into upper buckle chute 48 until the leading edge of the sheet abuts stop element 49.
  • the sheet buckles downwardly in the area of the inlet end 46 of buckle chute 50, and the buckled portion of the sheet enters the nip of rollers 42 and 52 which press the buckled portion to effect a fold.
  • the fold now constitutes a new leading edge.
  • Rollers 42 and 52 then feed the sheet downwardly to the inlet end 55 of buckle chute 56 where the leading edge is deflected into the buckle chute until it engages stop element 57.
  • Continued rotation of the feed rollers 42 and 52 causes the sheet to buckle again in the area of inlet end 55 of buckle chute 56, the buckles extending forwardly toward the nip of rollers 42 and 60.
  • Rollers 42 and 52 continue to feed the sheet causing the buckled portion to be picked up in the nip of rollers 42 and 60 to effect a second fold in the sheet which forms a new folded leading edge.
  • Rollers 42 and 60 then feed the fully folded sheet along the discharge path and out of the folding machine to be deposited on upper reach 68 of traveling belt 64 of a stacker tray (not shown).
  • rollers 38, 42, 52 and 60 are rotating at a much higher rate of speed than roller 18 so that the trailing edge of the first sheet is completely clear of the nip of rollers 38 and 42 before the leading edge of the next sheet arrives at that point.
  • rollers and shafts may be driven by a suitable power source through any desired power chain as will be apparent to those skilled in the art.
  • a unitary paperworking assembly 70 is located adjacent the discharge area of the folding machine. Assembly 70 is contained wholly within the folding machine and is cam actuable between operative and inoperative positions without being removed from the machine or pivoted from its normal plane of operation. As will be recognized, this makes assembly 70 particularly suitable for larger machines, or for those machines in which the frequency of change from operative to inoperative portions makes a removable or pivotable assembly impractical or undesirable.
  • paper working assembly 70 comprises a generally rectangular frame 72 terminating at either end in the previously discussed guide members 30a and 30b (FIG. 1).
  • a pair of side plates 71a and 71b (FIG. 2) formed integrally with frame 72 are pivotably journaled about bearings 73a and 73b in either end of the folding machine frame. This permits the entire assembly 70 to be pivoted out of the folding machine, as shown by dotted lines in FIG. 1, for major but relatively infrequent changes more fully discussed below.
  • a pair of shafts 78 and are rotatably supported respectively in bearings 73 on sideplates 71, and in sliding blocks 74 and 76.
  • Blocks 74 and 76 and shaft 80 are part of a movable subframe 81, more fully described below, which is manually actuated to render the paper working assembly operable or inoperable as desired.
  • Shafts 78 and 80 are preferably removable from the bearings 73 and blocks 74 and 76 for purposes of replacement or repair.
  • Each shaft carries a plurality of selected feeding rollers and working rollers; these cooperate with each other to simultaneously feed folded sheets and perform various operations thereon as they pass between the shafts 78 and 80 when assembly 70 is in an operative position.
  • shafts 78 and 80 are shown carrying two pairs of spaced apart feed rollers 84 and 86 for feeding folded sheets between the shafts.
  • Shaft 80 may also carry one or more scoring rollers 88 which each cooperate with a flat resilient roller 00 on shaft 78 to provide a score line on each folded sheet as it passes therebetween.
  • Shaft 80 may also carry one or more slitting rollers 92 which each cooperate with a grooved roller 94 to slit each folded sheet as it passes through.
  • Shaft 80 may further carry one or more perforating rollers 96 which each cooperate with a grooved roller 98 similar to roller 94 in order to form a perforated line across each folded sheet as it passes.
  • Feed rollers 84 and all of the working rollers 88, 90, 92, 96 and 98 are mounted so as to be axially adjustable on shafts 78 and 8022s well as removable from the shafts, so that any desired arrangement of feed rollers and working rollers may be set up in order to achieve a particular result. It is for this purpose that assembly 70 is pivotable from the front of the machine as shown in dotted lines in FIG. 1.
  • the bearings 73 rotatably supporting shaft 78 are fixedly mounted in sideplates 71.
  • Shaft 78 is driven through a gear 100 affixed to one end which meshes with an adjacent gear 102 connected to a convenient power source such as a power takeoff from the folding machine.
  • the connection of shaft 78 is not moved from its position even when, as shown in FIG. 1, assembly 70 is pivoted from the front of the folding machine for changes to the feeding and working rollers on shafts 78 and 80.
  • shaft 80 is movable in a vertical plane within the folding machine between operative and inoperative positions.
  • sliding blocks 74 and 76 in which the ends of shaft 80 are rotatably journaled, are respectively slidably mounted in slots 104a and 10411 in sideplates 71.
  • Blocks 74 and 76 are suspended from a carrier plate 106 by a pair of pins 108a and 10812 which pass freely through plate 106 and are upset to attach them thereto.
  • Coil springs 110a and 110b telescopically mounted on pins 108a and 1118b between blocks 74, 76, and plate 106, bias blocks 74 and 76 away from plate 106. As shown in FIG.
  • springs 110a and 1101) serve to maintain the rollers on shaft 80 resiliently biased against the corresponding rollers on shaft 78 to maintain their cooperating relationship. They also act somewhat like shock absorbers capable of adjusting for variations in the thickness of materials passing between shafts 78 and 80.
  • Carrier plate 106 is in turn suspended by bolts 112a and 112b from a top plate 114 forming part of subframe 81 (FIG. 2).
  • a pair of spacers 113a and 1111b are interposed between the upper surface of the carrier plate 106 and the underside of a cam follower plate 124 described below to maintain a fixed predetermined distance between the carrier plate 106 and the cam follower plate 124.
  • a pair of coil springs 116a and 1l6b are telescopically mounted on the spacers 113a and 11% between carrier plate 106 and top plate 14, and bias the carrier plate 106 downwardly with respect to the top plate 114 for a purpose made clear hereinafter.
  • the mechanism for shifting paperworking assembly 70 between operative and inoperative positions preferably comprises a cam 118 secured to a rotatable shaft 120 within a recess 122 in top plate 114. It will be recognized however that cam 118 may be replaced by an equivalent mechanical device such as a jackscrew, a lever arrangement, a wedge or the like.
