Definitions

  • ABSTRACT A bag stacking device to be located downstream of a bag welding machine wherein a bag support member is positioned to receive a stack of bags being built up and pinching fingers are positioned to rest on the lateral edges of the bag of the stack.
  • the present invention relates to a device for stacking bags.
  • a device for stacking bags In order to fabricate bags from a plastic tubing or film, it is known to use machines in which the tubing or film, carried along with a translational movement, is cut off and welded at definite intervals. The bags are then stacked at the outlet of this machine in order to make it possible for the operator easily to recover a large pile of bags.
  • French Pat. No. 1,594,567 discloses a bag stacking device in which the pile of bags is pinched at one of its ends, between an edge of the lower-weldingjaw extending downstream from the jaw along the direction of movement of the tubing, and a supporting component.
  • a holding component cooperates withthe supporting component in order to grip the bags when the supporting component moves away from the edge of the jaw, for stacking a new bag.
  • this device in which one of the ends of the bags is held pinched, is entirely satisfactory in the case of bags having only a single welded side, but it is more difficult to use it on bags having welds at both ends, because of the sticking of the welds of adjacent stacked bags. It is an object of the invention to overcome this disadvantage by using means which make it possible to pinch the bags by their side edges.
  • a device for forming a stack of bags from a film or tubing comprising at least two welding jaws at least one of which is mobile and carries means for cutting the tubing or film, characterised in that a supporting member is positioned downstream from the jaws and has a face for supporting the stacked bags, and in that at least one pair of pinching fingers is positioned to rest on the two side edges of the stacked bags to hold the bags on said supporting member.
  • FIG. 1 is a view in front elevation of the device for stacking bags mounted at the outlet of a machine for fabricating bags;
  • FIG. 2 is a view in longitudinal cross-section of the machine for fabricating bags and of the stacking device showing the main components;
  • FIG. 3 is a detail view, in front elevation, of the device
  • FIG. 4 is a cross-sectional view along the line IV-IV of FIG. 3;
  • FIG. 5 is a schematic view showing the first stage of holding a bag which hasjust been deposited on the pile;
  • FIG. 6 is the same view as in FIG. 3, showing the raising of the pinching fingers.
  • FIG. 7 is the same view as in FIG. 3, showing the bag inserted on the pile under the pinching fingers.
  • a machine for fabricating bags which comprises especially a pair of rotating pinch rollers l and 1a advancing a plastic tubing 2 along the direction F in which it is unwound in the machine has been partially represented in FIGS. 1 and 2.
  • Behind the rollers 1 and la are two lower welding jaws 3 and 4 which are fixed and co-operate with two upper welding jaws 3a and 4a which can move in a vertical plane.
  • a cutting component 5 is located between the upper weldingjaws 3a and 4a.
  • the jaws 3a and 4a and the cutting component 5 are mounted on a transverse beam 6 which is firmly fixed at its two ends to vertically extending rods 7'and 7a which are slidably mounted in bearings 8' and 8a firmly fixed to the frame 9 of the machine.
  • the rods 7 and 7a are equipped with wheels 10 and 10a which roll on earns 11 and 11a keyed to a shaft l2'rotated by a drive means (not shown).
  • the device for stacking the bags according to the invention is located downstream from the jaws 4 and 4a and comprises a supporting component 17 which consists of a bar fixed at the top end of at least one threaded rod 18 (FIG. I) screwed into a rod 19 slidably mounted in a cross-bar 20 fixed to the frame 9.
  • a supporting component 17 which consists of a bar fixed at the top end of at least one threaded rod 18 (FIG. I) screwed into a rod 19 slidably mounted in a cross-bar 20 fixed to the frame 9.
  • a ring 21 is screwed onto the threaded rod 18 and forms an abutment for the top end of a helical compression spring 22 the other end of which abuts the crossbar 20 so as to urge the supporting component 17 upwardly against at least one pair of pinching fingers 23 and 23a firmly fixed to sleeves 24 fitted on a transverse bar 25.
  • Each sleeve 24 carrying a finger can be moved along the bar 25 transversely to the direction of tubing advance and fixed along the width of the bags by means of the locking screw 26.
  • the bar 25 is firmly fixed at its two ends to two vertical rods 26 and 26a mounted for longitudinal sliding movement.
  • the rods 26 and 26a each carry a cam follower wheel 27 and 27a engaging a respective rotating cam 28 or 28a under the action of springs 29 and 29a fixed between the bar 25 and the frame 9, the said earns 28 and 28a being keyed onto the same rotating shaft 12 as are the earns 11, 11a.
  • This arrangement makes it possible to hold the pile of bags 30 between the upper surface 17a of the supporting component 17 and the fingers 23 and 23a which are resting on the side edges of the bags.
  • a holding component 31 On the transverse beam 6 which carries the movable welding jaws is a holding component 31 having slots 32 in which feet 33 and 33a are mounted for adjustment transversely and to be able to rest against the bag 14 and the supporting component 17 when the beam 6 is lowered.
  • the device according to the invention operates in the following manner.
  • the newly made bag 14 is placed on the pile 30 of bags made during previous operations of the machine, and while the jaws 3a and 4a are in the raised position as shown in FIGS. 3 and 4, the side edges 34 of the bag 14 are located above the fingers 23 and 23a and the pile of bags 30 is pinched at its side edges between the fingers 23 and 23a and the supporting component 17.
  • the beam 6 is then lowered in the direction of the arrow A by rotation of the earns 11 and 11a so as to bring the upper welding jaws 3a and 4a into contact with the fixed lower jaws 3 and 4 for welding the tubing 2.
  • the holding component 31 firmly fixed to the beam 6 is lowered so that the feet 33 and 33a pinch the bag 14 and the pile of bags 30 against the supporting component 17 as shown in FIG. 5.
  • the cams 28 and 280 lift the rods 26 and 26a in order to raise the fingers 23 and 23a past the top bag in the direction of the arrow B, as shown in FIG. 6.
  • the fingers are then located above the side edges 34 of the bag 14 as shown in FIG. 6. At this instant, the pile of bags is held down against the spring urged supporting component 17 only by the feet 33 and 33a of the holding component.
  • the fingers 23 then return to their original position following further rotation of the cams 28 and 28a to pinch simultaneously the side edges 34 of the bag 14 and the pile of bags 30 therebelow.
  • the beam 6 rises again in the opposite direction to the arrow A, so as to lift the upper jaws 3, 3a and the holding component 31, and to separate the feet 33 and 33a from the supporting component 17 as shown in FIG. 7.
  • the pile of bags 30 is then held by the fingers 23 and 23a again resting against the supporting component 17 and a new cycle can recommcnce for stacking the next hag.
  • the fingers 23 and 23a it is possible for the fingers 23 and 23a to be fixed in that the bar is firmly fixed to the frame 9 of the machine.
  • the feet 33 and 33a of the holding component 31 pushthe supporting component 17 back during their descent in opposition to the spring 22 and they thus ensure that the pile of bags is held against the said supporting component, whilst disengaging the fingers 23 and 23a of the supporting component in order to make it possible for the side edges 34 of the bag 14 to be transferred to below the fingers 23 and 23a in a manner similar to that represented in FIG. 6.
  • apparatus for forming stacks of bags from weldable film or tubing comprising a frame, mobile welding jaw means movably mounted on said frame, furtherjaw means mounted on said frame in the path of movement of said movable jaw means and cooperating with said mobile jaw means, means for advancing film or tubing along a path extending between said movable jaw,
