Definitions

  • the present invention relates to a device for stacking plastic bags arranged at the outlet of machines for the manufacture of these bags.
  • This axis is used in combination with two bag holding members on the axis and a retracting member of the rear part of the bag.
  • the thickness of the stack of bags is limited to a certain thickness due to the spacing of the mechanical members.
  • the support axis of the rear part is carried by means allowing the progressive retraction of said axis relative to the bag outlet member as the bags are stacked,
  • the device according to the invention allows due to the retraction of the support axis of the stack of bags, to have the upper part of the stack of bags located at the same level regardless of the thickness of this stack, relative to the outlet plane of the machine.
  • the bag stacking device shown in Figure 1 is located at the outlet of a bag making machine of which rolls 1 has been shown, the drive in the direction of arrow F of a sheath 2 in plastic and a pair of welding jaws 3, 3a combined with a sheath cutting member 4 and a guide member 5.
  • the welding and cutting members are mounted in a known manner in order to produce bags from the sheath 2.
  • an improved bag stacking device which comprises an endless belt 6 mounted on drive rollers 7, said belt carrying a stack of bags 8 of which the rear part 8a straddles a rotary roller 9 mounted between the outlet of the machine and the endless belt 6.
  • the roller 9 (FIGS. 1 and 2) is used in combination with a holding member 10 capable of coming to bear against the stack of bags 8 and of keeping the bags stacked on the roller 9.
  • the holding member 10 which is constituted by a bar is actuated in a known manner by means of a cam driven by the motor member of the machine so that it selectively occupies the positions shown in solid lines and in broken lines.
  • a flap 11 extending transversely to the direction of travel of the bags and which is intended under the action of a spring 29, to come to hold the bags permanently on the roller 9 as shown in solid lines in FIG. 1.
  • the flap 11 is capable of occupying an erasing position shown in broken lines (Fig. 1) to allow the passage of a retraction member 12 of the rear part 8a, of a bag, said member consisting of several son arranged transversely being capable of passing from position 12 to position 12a to effect the retraction of the bag when the flap 11 is in the position in broken lines.
  • the flap 11 and the retraction member 12 are actuated in a known manner by cams driven by the motor member of the machine.
  • the roller 9 (Fig 1 and 2) is mounted in free rotation at its two ends by means of rolling bearings 13 on axes 14 integral with arms 15 of which only one is shown in the drawing and which are fixed to a shaft 16 at keyways 17.
  • the tree 16 is rotatably mounted at its two ends in bearings 18 integral with the flanges 19 of the support frame, only one of which is shown in the drawing.
  • a bearing 20 On the shaft 16 is rotatably mounted by means of a bearing 20 at least one cage 21, which is integral with one of the parts of a freewheel 22 of which the other part is keyed at 23 on the shaft 16, said cage bearing one of its ends, an armature plate 24 which cooperates with a magnetic braking member 25 fixed by screws 26 on the frame 19.
  • An air gap X provided between the armature plate 24 and the magnetic braking member 25 can be adjusted by means of the bearing 20.
  • the arms 15 are extended beyond the shaft 16, by parts 15a, on which is hooked by one of its ends a spring 27, the other end of which is fixed to a member 28 of the frame of the machine, said spring 27 intended to return the roller 9 to the high position.
  • the raising of the holding member 10 allows the rollers 1, la, to bring onto the stack of bags 8, a determined length of sheath intended to constitute a new bag which after cutting and welding will have its rear part 8a, folded down by the retracting member 12 as described above.
  • the spring 27 is gradually stretched so that when the stack 8a reaches the desired thickness, the braking member 25 is actuated to ensure the latter is uncoupled from the plate 24 which is integral with the cage. 21, and this results in a release of the cage 21, which allows the pivoting of the shaft 16 in the opposite direction to the arrow Fl under the action of the spring 27.
  • the roller 9 returns to its initial position to receive a new stack of bags.
