Definitions

  • the invention is based on a method and a device for fitting valve bags with a side valve onto the filler neck of a filling machine according to the preamble of claims 1 and 2.
  • DE-PS-2 240 378 describes and shows a machine for placing valve bags on the filler neck of a machine.
  • the uppermost, flat-lying valve sack at its foot end is grasped by a first device from a supply stack, picked up and placed in an intermediate position in which the valve sack is completely in the vertical position, its valve being located at the head end of the pendulum which freely swings downward Valve bag is located.
  • the valve bag is then grasped and taken over at its head end by means of a further device, the first device detaching from the valve bag received and returning to its starting position.
  • valve sack When the valve sack is taken over, the valve is now opened by rotating the head end of the sack and the sack is thus transported by the second device and other means to a filler neck and placed thereon.
  • This method and this device are not suitable for attaching valve bags with a side valve.
  • DE-A-2 824 966 describes a method and an apparatus for handling valve sacks with a side valve, according to which it is possible to pick up the sack from a storage stack and to place it on the filler neck of a filling machine with the valve open.
  • the procedure here is such that the side valve of the valve bag located in the raised intermediate layer is first pre-opened, then opened maximally and approximately rectangularly by means of spreading tools inserted into the pre-opened valve, and finally is shaped back into an approximately circular shape suitable for attachment, after which the valve bag is attached .
  • stops, spreading and clamping tools with corresponding movement mechanisms are provided for this.
  • the device proposed for this purpose is constructed in a complex manner and has a stop for the valve opening for the valve opening as well as spreading and clamping jaws fastened to controlled arms with corresponding control mechanisms for their actuation.
  • the object of the invention is to improve the method mentioned in the introduction and a device therefor, with which or with which it is possible to simplify the side valve of valve bags which are to be plugged onto the filler neck of filling machines or with less construction effort to open in a clip-on shape.
  • Another advantage of the device is that it can also be used for conventional valve bags that have the valve in the block bottom. In this case, the pivoting action of the first suction device is eliminated, and furthermore the second suction device is completely out of operation. If the bag valve itself does not open sufficiently when the bag is picked up from the stack, an additional cylinder or a mechanism can assist and / or provide for the opening of the valve.
  • a z. B. made of plastic film valve bag 1 shown, which is closed in its empty state on its long sides two inwardly projecting folds 2, 3 and on its the top and bottom end forming short sides by welds 4 and 5.
  • a so-called side valve 6 is provided, the opening of which is indicated by 6a.
  • a device for receiving and plugging such a valve bag 1 onto the filler neck 7 of a filling machine 8, which is only partially indicated, consists essentially of a frame 9 or the like, as shown in FIGS. 2 and 3, of a platform 10, which can be raised and lowered thereon, on which a Storage stack 11 is mounted on valve bags, and from a generally designated 12 and carried by the frame arrangement for handling the stacked valve bags.
  • the arrangement 12 consists of a frame structure 13, a first suction device 14 and a second suction device 15.
  • the frame structure 13 is composed of a horizontal frame 16, a stand 17 which can be pivoted about a vertical axis and to which the frame is rigidly attached at one end, and a swivel cylinder 18 which is attached to the frame 16 and to a strut 19 of the frame 9 is articulated.
  • a horizontally movable carriage 20 is provided within the frame 16 and carries the two suction devices 14 and 15. The carriage is moved horizontally by a pneumatic cylinder 21 in order to move the two devices 14 and 15 between the bag receiving position and the bag attaching position. The latter is indicated by dash-dotted lines on the left in FIGS. 2 and 3.
  • the first suction device 14 comprises a pneumatic lifting cylinder 22, a joint 23 which is fastened to the outer end of the piston rod of the lifting cylinder 22, a swivel cylinder 24, the piston rod 25 of which is operatively connected to the joint 23 via a lever arm 26, and a suction arrangement 27 with preferably a plurality of suction cups 28, which are subjected to negative pressure via a connection 29 in a manner known per se.
  • the two cylinders 22 and 24 are attached to the carriage 20.
  • the second suction device 15 comprises a parallelogram 30, a suction arrangement 31 with preferably a plurality of suction devices 32, which can be subjected to negative pressure via an air connection 33, and an actuating cylinder 34 for moving the suction arrangement 31 back and forth in a controlled manner while maintaining its horizontal orientation in the horizontal direction to be able to.
  • the parallelogram 30 and the cylinder 34 are also articulated on the carriage 20.
  • the second suction arrangement 31 is oriented horizontally such that it is opposite the first suction arrangement 27 when it has been pivoted into its horizontal position.
  • the first suction arrangement 27 is moved downward and placed on the uppermost valve sack of the stack 11, in the region of the side valve 6 indicated in FIG. 3.
  • the top valve sack adheres the suction cups 28, and the arrangement 27 moves back a distance with the detected valve bag.
  • the arrangement 27 now pivots with the valve bag horizontally by approximately 90 ° into the dot-dash position shown in FIG. 2 and drawn out in FIG. 3.
  • the second suction device 31 then moves horizontally to the partially pivoted valve bag 1, so that the suction devices 32 on the other side of the valve bag also act on the bag in the region of the side valve 6.
  • the cylinder 21 is actuated so that the carriage 20 moves forward and thus transports the opened valve bag 1 to the filler neck 7 of the filling machine 8 (dash-dotted position in FIGS. 2 and 3).
  • the cylinder 18 pivots the frame structure 13, so that the valve bag 1, which is now in a completely vertical position, is pushed onto the filler neck 7 according to the arrow 35 in FIG. While the sack is now being filled, the device returns to its initial state, after which the described movement sequences are repeated for attaching the next valve sack.
