Definitions

  • the present invention relates to an apparatus for producing thermoplastic handle bags as mentioned in the preamble of claim 1 and as shown for example from GB-A-2 023 063.
  • T shirt bags Bags having the configuration of the bags produced by the subject matter of the present invention are generally referred to as "T shirt bags".
  • the construction essentially comprises the creation of inwardly directed folds or gussets in tubular web material which is sealed and cut are regularly spaced intervals to produce an envelope or a pillow having each end heat sealed.
  • Some existing procedures transport the envelope to a stacking station which may include upstanding members, such as fences, to accumulate successive gussseted and sealed envelopes to create a stack.
  • a stacking station which may include upstanding members, such as fences, to accumulate successive gussseted and sealed envelopes to create a stack.
  • a press having a knife shaped to remove a generally rectangular portion from the stack of web segments. The knife cuts through the stack of web segments such that the inner extremity of the gussets and a portion of one of the transverse seals is severed, thereby creating loops which can be grasped by hand or receive the forearm of a user.
  • Methods and machinery are presently available for improving stack registration by interconnecting the web segments along the trailing or leading edge to maintain stack registration during manual pickoff and punching.
  • Two known approaches are used. One involves providing heated pins or bars located adjacent the sealing station that are effective to tack weld or block the stack as it is being generated. The second approach involves a heated bar in contact with one marginal edge of the welded web segments to unify the successive segments as a stack is being created. To effect this association of web segments tack welding sometimes is restructed to the area of the bag edge which will be punched or cut out when the final stage of producing a T shirt bag is accomplished.
  • Certain approaches extend the tacking area of the successive bags along the entire margin of the web segment so that even after removing a rectangular segment, all of the bags are unified along the remaining edge portions. Whether heated pins are used or a heated blocking bar, the manual operation of removing the bag stack from the stacking table to the punching machine requires manual effort in removing the unified or blocked stack of bags from the bag making machine to the punching unit.
  • T shirt bag operations have resorted to cutting the rectangular segment from the stack of web segments on the bag machine.
  • the present state of the art incorporates rotary dies downstream of the seal bar to produce the rectangular cutouts.
  • This approach does fulfill the requirements of a high quality bag (one in which the rectangular cutout is cleanly made and accurately positioned) but the rotary dies and the machine elements supporting and rotating the dies are exceedingly expensive to insure proper continuous operation and on changing bag size, replacement of the rotary dies is an expensive alteration.
  • the object of the present invention is to eliminate the disadvantages of the known apparatus in question and to provide a continuously and effectively operating apparatus insuring a precise production of the thermoplastic handle bags in question.
  • the present invention may comprise means, synchronously operated with a bag machine associated therewith, for removing a portion of a web segment defining a bag from a predetermined location relative to the margins of such a segment, whereby the removing means operates within the time span within which the web segment is being severed and sealed by the bag making machine.
  • the means for removing a portion of the advanced web segment may include a stationary platen and a cam driven platen supporting clamping members and a knife shaped in accordance with the portion to be removed, the cam driven platen is designed to create forces that minimize bending in guide pins and bushing thereby insuring longevity and clean and accurate shearing of the web.
  • the portion of the web removed from the advanced web segment may be conveniently disposed out of line of the web path by providing a scrap conveyor for receiving and transporting the cutout portion of the web transversely of the machine.
  • a system of bag transporting conveyor belts enhanced maintaining the completed bag in a fixed position thereby insuring fold lines or creases to assume coordinate locations with respect to the margins of the bag.
  • a T shirt bag making apparatus is generally indicated by the numeral 10, and is cooperatively integrated with the operation of a bag machine of the general type shown in United States Patent No. 3,663,338.
  • the bag machine incorporates a twin sealing device 12, details of which are shown in United States Patent No. 4,019,947.
  • Draw rolls 14, intermittently rotated by the bag machine advance a selected segment of gusseted web W between the sealing device 12 toward a reciprocating punching mechanism 16 that removes a generally rectangular web portion from the leading portion of the advanced web segment.
  • Upper and lower transversely spaced conveying means 18 and 20, respectively, direct and assist in properly positioning each web segment relative to the mechanism 16 and thereafter transport the completed bag to folding means 22.
  • the folded bag is then discharged to a carton or other suitable container supported on an indexable belt 24.
  • the belt 24 may incorporate spaced upstanding fences 26 which, when positioned at the discharge at the folding means 22 define a stacking station 28 confining the folded bags to assume a stack.
  • the punching mechanism 16 for cutting and removing a generally rectangular slug of material from the leading portion of the web segment or segments being fed, is positionable longitudinally relative to the seal bar 12 to insure that the rectangular slug removed thereby includes cuts penetrating the inward folds of the gussets and the leading seal at spaced intervals.
  • Figure 1A illustrates the cutting operation wherein a typical T shirt bag 30 is formed with inwardly extending gussets having a crease line terminating at 32. Both ends of the bag are sealed along lines 34 and a small portion of web material, usually referred to as a skirt 36, extends beyond the transverse zone of the seal 34.
  • the cutout C.O. takes the form of longitudinal incisions 38, cutting the skirt 36, the seal 34 and the inner crease of the gussets 32.
  • the incisions 38 are interconnected by a transverse incision 40 thereby separating the cutout from the web segment and accordingly producing a T shirt bag.
  • the reciprocating mechanism 16 for making the cutouts or removing a generally rectangular portion of material from the leading portion of the web segment operates within the time in which the seal bar 12 is creating the seals and severing the advanced web segment.
  • the mechanism 16 is positioned longitudinally relative to the seal bar 12 to produce T shirt bags of desired length.
  • Figures 2, 3, 4 and 5 illustrate the constructional features of the reciprocating mechanism 16.
  • the preferred construction includes mechanisms for translating the position of the mechanism 16 with respect to the seal bar, depending upon the length of the bag to be made. Translation is achieved by providing transversely aligned and spaced upstanding plates 42 having rigidly mounted at the upper edge and on the inner surface, gear racks 44 meshing with gears 46 mounted on a shaft 48 which is rotated by a hand wheel 50 secured to a lateral extension of the shaft 48.
  • the upper edge of the plates 42 provides a support for a box-like structure 52 comprising an upper plate 54 formed with downturned portions 56 to thereby form a transversely extending channel (Figure 5).
  • the reciprocating mechanism 16 is a "2-up head" meaning that two webs are simultaneously processed. Accordingly, the mechanism 16 is constructed to simultaneously process two webs and this is accomplished by providing duplicate (in construction and mode of operation) cutting positions 70 and 72. Accordingly, in describing the reciprocating mechanism 16, it is to be understood that interchangeable reference may be made with respect to the cutting positions 70 and 72.
  • the cutting and removing of a generally rectangular portion from the thermoplastic web meets the objective of providing a self contained assembly which can be moved forward or away from the seal bar 12 in response to the length of bags desired.
  • the constructional arrangement provides a mechanical drive designed to balance the dynamic forces during the cutting operation which insures longevity and trouble free operation since unbalanced forces which would tend to cause deterioration between machine elements that move relative to each other are balanced such that the net forces are reduced to an absolute minimum.
  • the mechanism 16 includes an upper reciprocating platen 74 and a lower stationary platen 76.
  • a series of actuators 92 and 93 are mounted in threaded bores formed in the upper platen 74.
  • the rods 92a and 93a are in turn fixed to an outer presser plate 80 and a central presser plate 94.
  • the rods 92a and 93a are continually biased toward an extended position either by a spring or air maintained at a selected pressure.
  • the presser plate 80 is formed with a rectangular opening 82 having attached to its lower surface a compress- able elastomeric strip 84 even with the opening 82.
  • the upper platen carries, by means of a mounting block 86, a knife 88 formed to produce cuts along lines 38 and 40.
  • the knife 88 is located adjacent to the rectangular opening 82.
  • the central presser plate 94 is also provided with an elastomeric strip 96.
  • the lower stationary platen 76 is formed with a generally central rectangular central opening 98 conforming in shape and size to the rectangular opening 82 in presser plate 80.
  • the insert 100 is formed with a flange 102 and a central opening 104 through which, as will be presently explained, the cutout portion of web material passes for reception by a scrap conveyor 106 operating to convey scrap material transversely of the path of the gusseted web.
  • the insert 100 together with the lower platen 76, provides a slot 108 for receiving the knife 88.
  • the bag machine drive includes a main input shaft 110 having keyed thereon a tooth pulley 112 driving a similar pulley 114 by a timing belt 116 held in tension by an idler pulley 118.
  • Pulley 114 and a pulley 122 are mounted on a clutch brake shaft 120.
  • Pulley 122 drives a timing belt 124.
  • the timing belt passes around an idler pulley 126 and a pulley 128 rotatably mounted on a stub shaft 130 carried by the bracket 66.
  • a grooved pulley 132 driving a pulley 134 by a belt 136.
  • the pulley 134 is keyed to a shaft 139 driving the scrap conveyor 106.
  • the timing belt 124 is wrapped around a timing pulley 138 keyed to one of the shafts 62, thereby driving both shafts by virtue of the meshing gears 68.
  • a large arc of contact of the belt 124 around the pulley 138 is achieved by idler pulley 140 and 142.
  • the pulley 142 is rotatably mounted on a short stub shaft 144 carried by the bracket 66 as shown in Figure 3.
  • the upper platen 74 is driven downwardly to project the blade 88 through the portion of the web located within its projected area. Reciprocation of the platen 74 is accomplished by rigidly mounting, laterally spaced ears 146 to its upper surface and rotatably mounting therebetween, on a short pin shaft 148, a cam follower roller 150.
  • the upper platen 74 is reciprocated by cams 152 and 154 ( Figure 4) rigidly secured to the shafts 62 which, as mentioned above, are concurrently driven by the belt 124 through the agency of the meshing gears 68.
  • the shafts 62 and the cams associated therewith are rotated in opposite directions and therefore, the forces produced which may tend to create or impose bending moments on the platen 74 balance each other and accordingly smooth action and extended life between relatively moving surfaces result.
  • the upper platen 74 is guided for rectilinear movement by guide pins 156 each of which have one end secured in the lower platen 76 and the other end fixed in an ear 158 rigid with the outer ribs 58.
  • compression springs 160 bias the platen 174 upwardly and insure that rolling contact between the cam follower rollers 150 and the cams 152 and 154 is maintained.
  • the scrap conveyor 106 has a feeding reach 162 extending below both of the inserts 100 so that the punched out portion of web material may be transported laterally of feed path of the web material.
  • the scrap conveyor includes a driven roller 163 mounted on the shaft 139, idler rollers 164 and a return each diverting roller 166.
  • Positive ejection of the scrap of web material cut by the knife 88 is preferably accomplished by providing a tube 188 connected to a source of pressure air and being fixed to the upper platen 74.
  • the tube partially projects into the central presser plate 194.
  • An enlarged opening 190 insures the diffusion of pressure air to positively remove the cutout portion of web material and propel it to the conveyor 106.
  • Each of the levers 168 are formed with an integral pocket 178 in which is rotatably mounted a cam follower roller 180, held in rolling engagement with cams 176 by the springs 174. In view of this arrangement, during each cycle of operation, the levers 168 are cammed downwardly squeezing the completed bag between the belts 18 and 20 for advancement to the folding means 22.
  • the upper and lower conveying means 18 and 20 respectively comprise, as shown in Figure 3, a plurality of laterally spaced relatively narrow flat belts, some of which are diverted around reciprocating unit 16 so that their path does not fall in the projected area of the knife 88 and certain of the belts are directed over the lower platen 76.
  • a plurality of idler rollers all of which are collectively identified by the numeral 182
  • divert belts 20a Figure 5 to pass under the cutting knife 88 while belts 20b pass over the lower platen 76.
  • Diversion of the upper conveying means 18 follows a similar pattern by diverting reaches 18a while reaches 18b are adjacent the reaches 20b.
  • All of the belts 18 diverted around the reciprocating unit 16 pass around roller 172 and are tracked as shown in Figure 5 by idler rollers 184 which are rotatably supported in end plates 186 attached in any suitable manner to the frame of the reciprocating mechanism 16.
  • the leading portion of the segment is positioned within the projected area of the knife 88 to effect cutting along the longitudinal incisions 38 and the transverse incision 40 as described above.
  • the twin sealing device 12 descends to effect sealing and severing of the advanced web segment.
  • the reciprocating mechanism 16 descends clamping the web by presser plate 80 and the central presser plate 94 firmly clamping the web before the knife 88 cuts the web along lines 38 and 40.
  • the cutout C.O. is removed by the air issuing through tube 188 afterthe upper platen raises, releasing the clamping pressure of the presser plate 94 and then the presser plate 80.
  • the cutout portion is received on conveyor 106 and discharged.
  • the folding mechanism comprises first and second sets of folding rolls 192 and 194, respectively.
  • the bag is sequentially directed to the nip of folding rolls 192 and 194 by air issuing from air tubes 196 and 198 directing jets of air to the nip of the folding rolls.
  • the bag with the single fold is directed by belts 18 between the wires 206 and a generally L shaped wire 210.
  • the air tube 198 is programmed for operation by a time delay and the jets of air directed toward the nip of folding rolls 194 makes one additional fold.
  • the twice folded bag is discharged to the stacking station 28.
  • Figure 10 diagramatically illustrates the action of the folder 22. Upon accumulating a stack having a selected number of bags the conveyor 24 is operated to transport the bag stack away from the stacking station 28.
