Definitions

  • a guide plate can be adjusted in parallel by two synchronized spindles.
  • a third, also synchronized spindle with half a pitch adjusts another organ by half an amount.
  • the axes of the three spindles lie in a common plane.
  • the present invention has for its object to provide a packaging machine with a continuous path for products, a wrapping material feed, folding, sealing and trans port means to be designed such that it can be easily adjusted for different widths of the products transversely to the transport direction.
  • Fig. 2 is a plan view, partly in section, and
  • FIG. 3 shows a section along the line III-III in FIG.
  • the device 1 is used to pack groups 2 of upright, flat food slices, eg biscuits.
  • the groups 2 are fed on a first conveyor 3 to the device 1 in the conveying direction A at regular intervals.
  • the group 2 is enveloped by a wrapping material film 4.
  • the film 4 is drawn off in cycles from a supply roll 5 transversely to the transport direction A and cut to the appropriate length by a knife 6.
  • the center of the cut piece of film is in the central plane M.
  • the next group 2 is transported, it becomes encased by the piece of film 7 and formed by two transverse sealing jaws 8 a sealing seam.
  • the enveloped groups 2 are then moved by the comb 1 by a comb-like conveyor in cycles. You will first get to a ordered end-face folding device 10.
  • Each device 10 consists of two triangular sheets 11, which are offset from one another transversely to the direction of transport, overlap, symmetrically arranged with respect to one another and to the central plane M.
  • a sealing device 12 This consists on both sides of a number of sealing jaws 13 which can be moved transversely to the transport direction A and which are moved against one another by the lifting element 14 and seal the sealing seams on the end face.
  • the packages 15 are pushed onto a further conveyor 16, which transports them away.
  • the folding member 10 and the sealing device 12 on each side are each mounted on a carrier plate 20.
  • the plates 20 are slidably guided on three circular cylindrical tubes 21.
  • one of the bores 22 of the plates 20 as a cylindrical sliding seat bore, a second as an elongated hole with a sliding fit in the vertical direction, and the third as a bore 22 of larger diameter.
  • the tubes 21 have a shoulder 23 on both sides and a thread 24 which is inserted through a plate 25, 26 each.
  • the tubes 21 are fastened to the plates 25, 26 by means of nuts 27.
  • the plates 25, 26 can be adjusted in height by synchronously driven threaded spindles 28 in order to adjust the device 1 to different diameters or Adapt the shapes of the panes of group 2.
  • a radial bearing 32 is inserted in each of the two pipe ends and secured axially in the pipe 21 by screws 33.
  • a threaded spindle 34 with a right-hand thread 35 and a left-hand thread 36 is rotatably mounted in the bearings 32.
  • the threads 35, 36 have the same pitch.
  • a sprocket 37 is attached to the spindle 34 on one side.
  • the three sprockets 37 are connected to one another via a chain 38.
  • the spindle 34 is secured against axial displacement by the chain wheel 37 and a locking disk 39.
  • a nut 42 is screwed onto each of the threads 35, 36. Each nut 42 is secured against rotation by a pin 43.
  • the pin 43 is loosely seated in a transverse bore 44 in the nut 42 and extends through a longitudinal slot 45 of the tube 21.
  • the pin 43 is inserted in a bore 46 in a plate 47.
  • the plate 47 is fastened to the supporting plate 20 with screws 48.
  • One of the screws 48 also secures the pin 43.
  • the sectional view of the left tube 21 is shown rotated by 90 °. In reality, all the slots 45 are vertically below the spindles 34. This effectively prevents the spindles 34 from becoming dirty. This is particularly important when packaging biscuits.
  • One of the spindles 34 also has a handwheel or a crank 49.
  • the connecting lines 50 of the axes 21 of the spindles 34 form a polygon, in the exemplary embodiment shown a triangle.
  • the three-point mounting means that the plates 20 are prevented from tilting secured by transverse forces which occur when the sealing seams are sealed, even when the load is unequal.
  • the described adjusting device requires few, simple and mostly identical parts. The machine can be easily adapted to different lengths of groups 2.
  • the support plates 20 can also be slidably guided on two separate cross bars which are fastened in the plates 25, 26. In this case, all of the bores 22 have a larger diameter than the tubes 21.

Abstract

L'invention concerne une machine servant à emballer des groupes de produits alimentaires discoïdes, notamment de biscuits, contigus placés sur chant. Afin de pouvoir ajuster ledit dispositif à des groupes de différentes longueurs, les éléments de pliage et de scellement sont fixés sur des plaques porteuses (20), dont l'intervalle peut être ajusté à chaque fois par au moins trois tiges filetées (34). Les tiges (34) sont montées dans des tubes (21) solidaires du boîtier, pourvus d'une fente longitudinale (45), et sont reliées entre elles par une chaîne (38). Des écrous (42) vissés sur le filetage (335, 36) sont reliés à chacune des plaques porteuses (20) correspondantes par l'intermédiaire d'une goupille (43) qui fait saillie dans la fente (45). Ce dispositif de structure simple est solide et permet un ajustement rapide et fiable.
