Definitions

  • the invention relates to a device for twisting the extremities of a packing wrapping consisting of a means for supplying and discharging objects about which the packing wrapper has to be twisted by pairs of twisting claws, said pairs of twisting claws being hingedly mounted about levers to oppositely rotating heads, means being provided to move both claws toward and away from each other, one of the pairs of claws being adapted to receive a stick attached to the object.
  • a similar device is known from GB-A-328145.
  • the hinged joints of one of the pairs of twisting claws have to be at a relatively large distance of the spheroidal portion of the object. This requires long levers, which results in high centrifugal forces. Consequently, it is nearly impossible to obtain a device whose number of revolutions is sufficient for keeping up with the high production rate of modern machines for the production of lollipops.
  • the device can be designed such that the pair of claws in question in each wrapping cycle makes three and a half revolutions with the object and half a revolution without the object.
  • the head of the one pair of claws then consists of a flange portion for guiding a steering rod for the toothed rack, and a bridge portion confronting the mounting plate in balance with regard to the bridge portion.
  • the levers of the pair of twisting claws are provided with a counter mass beyond the hinged joint of the head.
  • the device shown in the drawing consists of two heads 1 and 2 which rotate in opposite directions for twisting the extremities of a packing wrapping 3 shown by dotted lines in Figure 1, so that an object 5 provided with a stick 4, such as a lollipop, can efficiently be provided with a packing having an attractive appearance.
  • the left-hand head 1 in the drawing is provided with hinged levers 6 which at their free ends have the appearance of a claw 7.
  • the hinging of these levers is effected in a known fashion in that a toothed rack 8 is movable in the head in axial direction of the head.
  • the teeth of this toothed rack 8 engage teeth applied to the circular rear end of the levers 6 positioned about the pins 9. Because of safety it is necessary that the claws are closed by a spring pressure and are opened with force.
  • the right-hand head 2 in the drawing is provided with hinged levers 10 which at their free ends have the appearance of a claw 11.
  • the hinging of these levers is effected by a stepped toothed rack 12 which engages teeth applied to the rear ends of the levers 10 positioned about the screwed connections 13.
  • the head 2 consists of a cylindrical flange portion 15 with a guide bush 16 for guiding a steering rod 17 for the toothed rack 12.
  • the flange portion 15 is integral with a bridge portion 18 which in its turn is integral with a mounting plate 19 which supports the levers 10 by means of the screwed connections 13.
  • the mounting plate 19 is positioned preferably diametrally opposite the bridge portion 18.
  • the bridge portion is therefore of a proportionally thick construction.
  • the mounting plate 19 may also be fitted out with edges (not shown) dropping over a short distance for guiding the toothed rack 12.
  • the levers 10 may continue to beyond the screwed connections 12 in order to constitute balancing masses 20.
  • the claws 7 of the left-hand head 1 are made of plastic because they need not be heated and are therefore not subject to high centrifugal forces.
  • For the claws 11 are made of metal indeed, because they can be heated in a way not relevant.
  • the above described device operates in the following way:
  • the object 4/5 and the packing wrapping 3 arrive in the pairs of claws 6 and 7 according to the sense of arrow 21.
  • the object remains at rest for a part of the cycle of the device, for instance for three and a half revolutions of head 2.
  • the lollipop is retained by a device which is driven by a Malthezer cross. In consequence the device moves 120° of a 360° cycle and is 240° at rest.
  • the head 2 rotates during this stationary period 240/360° x four revolutions.
