  • the two tape accumulation boxes 9, 9' are mounted at a predetermined place on the base 1 between the side frames 4, 4 and each have a width W and depth D (the depth is the dimension as measured from the front side to the rear side of the box).
  • a nip roll assembly comprising a tape feed roll 17 adapted to be driven by a motor 10 and a pressure roll 18, a tape traverse mechanism and a tape shaking-off device comprising two rocking plates 52, 53 adapted to rock upon receipt of the tape from the nip roll assembly.
  • an endless belt 14 is wrapped or trained about a transverse mechanism drive pulley 16, a pulley 15 mounted on the feed roll 17 and a pulley 13' mounted on a disc 57 which is adapted to drive a connecting rod 56 connected to a link rod 54 which is in turn connected to two rocking plates 52, 53 which are in turn pivoted at the upper ends to parallel and spaced shafts 50, 51 and the belt 14 is driven from the motor 10 through an endless belt 12 trained about a pulley 11 on the motor 10 and the disc 57 to drive the nip roller assembly, tape traverse mechanism and shaking off device at the same time.
  • the tape traverse mechanism comprises a worm 20 which is driven by the pulley 16, a sprocket wheel 22 adapted to be rotated by a worm wheel 21 meshing with worm 20, an endless chain 25 trained about the sprocket wheel 22 and a sprocket wheel 23 which is mounted on a chain box 26 on one side of which a slide plate 27 is supported for reciprocal movement by the chain 25.
  • the above-mentioned slide plate 27 is provided with a vertical slot 29 for receiving a pin 30 on the chain 25.
  • a horizontal support bar 24 is secured to the slide plate 27 and a first pair of closely spaced guide bars 31, 32 extend uprightly at one end of the support bar 24 and a second pair of closely spaced guide bars 31', 32' extend uprightly at the other end of the support bar 24.
  • the tapes T are guided through the clearances between the pairs of guide bars 31, 32 and 31', 32', respectively, with the tapes each twisted a quarter turn upstream and downstream of the guide bars 31, 32 and 31', 32' (see Figure 2) so that each tape width lies horizontal on the upstream roll (unreferenced) and on the downstream roll 17 but is vertical as shown when passing between the guide bars 31 and 32 or 31' and 32' respectively.
  • the tapes T are guided for traverse movement as the slide plate 27 moves reciprocally.
  • Rotational movement is imparted to the feed roll 17 as the pulley 15 rotates and the pressure roll 18 is moved into contact with the feed roll 17 with a predetermined pressure bythe operation of a handle 19 to pinch the associated tape T therebetween to transfer the tape.
  • the tape shaking-off-rocking mechanism comprises the above-mentioned parallel and spaced rotary shafts 50, 51 to which the upper ends of the two rocking plates 52, 53 are pivoted to define the tape receiving clearance therebetween just below the nip of the pinch roll assembly.
  • the rocking plates 52, 53 are connected together on their opposing sides by means of the connection linkage 54 which is in turn connected to the disc 57 by means of the connecting rod 56.
  • the rocking plates 52, 53 rock as shown by the solid and two-dot lines in Figure 2 to shake the tape off which tape is then folded upon itself to form folded layers which adapt to the depth D of the box 9.
  • the rocking plates 52, 53 are pivoted at the upper edges 101, 102 thereof to the shafts 50, 51 which in turn extend parallel to each other and are secured at the opposite ends to the side frames 3, 3.
  • the rocking plates 52, 53 are connected together at their intermediate points between the upper and lower ends thereof by the linkage 54 which is in turn rotatably supported by means of pins 103,104 on the rocking plates 52, 53.
  • the linkage 54 is operatively connected through a rotary shaft 105 to one end of a connecting rod 56 which is reciprocally moved by a constant stroke given by rotation of the disc 57.
  • rocking plates 52, 53 are integrally formed at their opposite side edges with flanges 106, 107, respectively, for preventing the tape from escaping out of the confinement defined by the rocking plates.
  • the length of the rocking plates 52, 53 is so selected that the rocking plates are allowed to rock by the disc 57 through the connection rod-56 in conformity with a desired folding-up width for the tape within a rocking movement range determined by the abutting of the flanges 106, 107 at the lower ends against each other.
  • the rocking plates 52, 53 increase the width of the guide opening defined therebetween soon after the momentary narrowing of the opening as the plates continue to rock to thereby eliminate the accumulation of the tape within the opening and as a result, the successive shaking off of the tape can be effected without substantially disturbing the folded-up condition of the tape.
  • a mechanism is provided which is adapted to press against the tops of the stacks of folded tapes within the accumulation boxes 9, 9'.
  • two parallel rotary shafts 64, 74 extend between and are suitably journalled in the lower side frames 4, 4 in a position just above the front upper edge 81 of the accumulation boxes 9, 9'.
  • Pressure plates 5, 7 each having the width substantially corresponding to one half of the width W of the accumulation boxes 9, 9' are secured on the rotary shaft 64 whereas two pressure plates 6, 8 similar to the pressure plates 5, 7 are secured on the rotary shaft 74.
  • One end or the left-hand end ( Figure 1) of the rotary shaft 64 protrudes outwardly of the associated side frame 4 and has an arm 63 secured thereto. The end of the arm 63 is pivoted to the outer end of the piston rod 62 of an air cylinder 60 which is in turn pivoted to a rotary shaft 61 secured to the adjacent vertical frame 2.
  • One end or right-hand end (as seen in Figure 1) of the rotary shaft 74 protrudes outwardly of the associated side frame 4 which opposes the side frame 4 from which the above-mentioned end of the rotary shaft 64 extends and has an arm 73 longer than the arm 63 secured thereto.
  • the end of the arm 73 is pivoted to the outer end of the piston rod 72 of an air cylinder 70 which is in turn pivoted to a shaft 71 secured to the associated vertical frame 2.
  • the pressure plates 5, 7 and pressure plates 6, 8 are connected to the rotary shafts 64, 74 by means of shorter and longer support arms 65, 75, respectively.
  • the longer arm 75 supporting the pressure plates 6, 8 is provided with a notch 76 in which the rotary shaft 64 is adapted to be received when the pressure plates 6, are pivoted from the upright one-dot line position as shown in Figure 2 to the horizontal position as shown in Figure 1.
  • the two tapes T are guided about the stepped tension regulator guide roll C and passed through the clearances defined between the upright guide bars 31, 32 and 31', 32' of the traverse mechanism, respectively, with their breadth disposed uprightly so that the tapes T are suspended down through the clearances defined between the respectively opposing rocking plates 52, 53 and 52', 53', respectively, while being pinched by the cooperating feed rolls and pressure rolls 17, 18 and 17', 18', respectively.
  • the tapes T are advanced by the rolls 17, 18 which are driven by the belts 12, 14 wrapped about the pulleys 11, 13 and 13', 15, 16, respectively.
  • the pulley 16, worm 20, worm wheel 21, sprocket wheels 22, 23 and chain 25 are operated to move the pin 30 on the chain 25 which engages in the elongated slot 29 in the slide plate 27 whereby the slide plate 27 moves laterally along the side of the chain box 26.
  • the support bar 24 secured to the slide plate 27 and the upright guide bars 31, 32 and 31',32' at the opposite ends of the slide plate 27 also move to traverse the tapes T in the axial direction of the feed roll 17 whereby the reciprocal traverse movement of the tapes T is effected while being regulated depending upon the space between the sprocket wheels 22, 23.
  • the two rocking plates 52, 53 also reciprocally rock as shown by the two-dot lines in Figure 2 on the stroke depending upon the rotation of the disc 57 whereby the tapes T fed between the plates are shaken off in the depth direction D of the accumulation boxes 9, 9' and in succession folded upon themselves within the boxes 9, 9' as shown in Figure 2 to form tape layers folded to form a zigzag attack in the width direction W of the boxes.
  • the piston rods 62, 67 of the air cylinders 60, 70, respectively, are maintained in their extended positions so that the pressure plates 5, 6, 7, 8 can be maintained in their upright positions until the accumulation boxes 9, 9' are filled with the folded tapes whereby the shaking-off of the tapes will not be impeded.
  • reference numerals 40, 41 denote microswitches which are adapted to detect the opposite ends of the support bar 24 having the guide bars 31, 32, and 31', 32' at the opposite ends, respectively, when the bar 24 reaches either extreme of its traverse movement stroke.
  • the microswitches 40, 41 are connected to their associated counters which count the number of traverse movements of the support bar 24 during the tape stacking operation as mentioned hereinabove.
  • the counters have stored therein the number of traverse movements to indicate when the top of the stack of folded tapes T is positioned above the upper edges 81 of the accumulation boxes 9, 9'.
  • the compressed air supply control system for the air cylinders is actuated and as shown in Figures 8 and 9, the operation of the control system is so related to the operation of the above-mentioned microswitches 40, 41 that during the tape folding and stacking operation, the pressure plates 6, 8 adapted to press against the tape stacked in one half portion of the width W of the associated accumulation box fall down when the tape is not shaken off in the half portion of the box whereas the other pressure plates 5, 7 are erected and as the tape traverse movement proceeds, when the tape is shaken off in the half portion of the width of the box, the pressure plates 6, 8 are then erected and the now erect pressure plates 5, 6 fall down and, thus, the pressure plate erecting and falling-down operations are timed so as not to impede the traverse
  • Figure 7 is a view showing the pressing step.
  • the pressure plate 5 falls down as shown by the two-dot chain line and the flat pressure face 80 of the pressure plate 5 presses the top F of the tape stack down to the position as shown by the line 80' which is below the upper edge 81 of the box 9 whereupon the pressure plate 5 erects itself to the upright position and the succeeding tape section is folded onto the top F of the previous tape stack.
  • all of the tape stacked in the box can be compressed to gradually increase the compactness of the tape stack. In this way, any abrupt compression on the tape stack is avoided to thereby eliminate possible unnatural distortion and/or creasing of the tape.
  • the amount of tape stacked in the accumulation boxes exceeds four times that of the conventional accumulation boxes into which the tape is accumulated therein by only the shaking-off and folding and two times that in the conventional roller pressing-folding method.
  • the tape feed speed in the apparatus of the invention is quite high and irregular folding and clinging of tape about rollers which were seen in the conventional apparatus of the type are eliminated.
