Definitions

  • the invention relates to a method and a device for attaching in particular valve bags with side valves to the filler neck of a filling machine.
  • DE-PS 22 40 378 describes and shows a machine for fitting valve bags onto the filler neck of a filling machine.
  • the uppermost, flat-lying valve bag at its foot end is grasped by a first device from a stack of stocks, picked up and placed in an intermediate position in which the valve bag is completely in the vertical position, its valve being on the head which freely swings below end of the valve bag.
  • the valve bag is then detected and taken over by means of a further device at its head end, in that the first device detaches from the valve bag received and returns to its starting position.
  • the valve sack is taken over, the valve is now opened by rotating the head end of the sack and the sack by the second device and others Means transported to a filler neck and placed thereon.
  • This method and this device are not suitable for fitting valve bags with side valves.
  • the object of the invention is therefore to provide a method and a device with which it is possible to fit valve sacks with a so-called side valve onto the filler neck of filling machines.
  • the method according to the invention is characterized in that the uppermost, essentially flat-lying valve bag is grasped by means of at least one suction device from a stack of stocks on one side in the area of the bag valve and placed in an intermediate position is brought, in which at least the sack end having the side valve is in the vertical position, that the valve sack is then detected on its other side in the region of the side valve by means of at least one further suction device and the valve is opened by actuating this suction device and with the participation of the first-mentioned suction device and that the valve bag with the side valve opened in this way is placed on a filler neck of the filling machine with the suction device still holding open.
  • a device for carrying out such a method is characterized by a first suction device operated with negative pressure, which can be moved in the vertical direction in order to receive a flat valve bag on one side thereof in the region of the side valve and to bring it into an at least partially vertical intermediate layer and is designed to be pivotable about a horizontal axis, by means of a second suction device operated with negative pressure, which is arranged opposite the first suction device with respect to the pivot position determining the intermediate position and is movable in the horizontal direction in order to prevent the latter To open the side valve of the valve bag, and by means of a further device for transporting the opened valve bag and applying it to a filler neck of the filling machine.
  • valve bags with so-called side valve fully automatically from a supply stack and securely stuck on the filling spout of a filling machine or thiocyanate, the ⁇ .
  • the supply of valve sacks lying flat on top of one another and forming a supply stack which has proven itself particularly for film sacks, can be used, it also being ensured that the attached sacks.
  • Valve bag is in the vertical position and can be filled to volume.
  • Each individual valve sack is initially only partially taken up with the first suction device, ie the head end of the valve sack having the side valve is picked up, while the rest of the sack is still supported on the supply stack.
  • valve sack The head end of the valve sack is then turned into a vertical one Intermediate position pivoted, the remaining sack still essentially being supported on the stack.
  • the second suction device engages on the other side of the valve bag in the region of the valve and opens the bag valve by a short backward movement, so that the bag can now be transported to the filler neck and attached to it with the valve kept open.
  • Another advantage of the device according to the invention is that it can also be used for conventional valve bags which have the valve in the cross bottom.
  • the pivoting activity of the first suction device is eliminated, and furthermore the second suction device is completely out of operation.
  • an additionally attached cylinder or a mechanism can assist and / or provide for the opening of the valve.
  • FIG. 1 shows a valve bag with a side valve in a top view
  • FIG. 2 shows a device for carrying out the mentioned method in a greatly simplified form and in a side view
  • FIG. 3 shows a further simplified view of the device according to FIG. 2.
  • Valve bag 1 made of plastic film is shown, which - in the empty state, has two folds 2, 3 projecting inwards on its long sides and closed by weld seams 4 and 5 on its short sides forming the head end and foot end.
  • a so-called side valve 6 is provided, the opening of which is indicated by 6a.
  • Valve bags with a side valve are also known which have no folds 2, 3.
  • 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, essentially consists of a frame 9 or the like, of a platform 10 mounted and liftable thereon, on which a supply stack 11 is mounted on valve bags, and from an arrangement, generally designated 12 and carried by the frame, 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, of a stand 17 which can be pivoted about a vertical axis and on which the frame is at one. End rigid. is attached, as well as "from a swivel cylinder 18, which is articulated on the one hand on the frame 16 and on the other hand on a strut 19 of the frame 9.
  • a horizontally movable carriage 20 which holds 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 being indicated by dash-dotted lines on the left in FIGS.
  • the first suction device 14 comprises a pneumatic lifting cylinder 22, a joint 23, which at the outer end of the Piston rod of the lifting cylinder 22 is fastened, 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 device arrangement 27, preferably with a plurality of suction devices 28, which are connected via a connection 29 in a manner known per se with negative pressure be charged.
  • 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 several

  • 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 device described above works in the following manner. It is assumed that a flat-lying valve bag is to be picked up from the supply stack 11 placed on the platform 10 and to be placed on the filler neck 7 of the filling machine 8.
  • the first suction arrangement 27 is moved downward and placed on the uppermost valve sack of the stack 11, in the area of the sack valve 6 indicated by the dashed line in FIG. 3 on the suction cups 28, and the arrangement 27 moves back a distance with the detected valve bag.
  • the arrangement 27 By actuating the cylinder 24, the arrangement 27 now pivots with the valve sack h tal by approximately 90 ° into the dot-dash position shown in FIG. 2 and drawn out in FIG. 3.
  • the second suction arrangement 31 By actuating the cylinder 34, the second suction arrangement 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 engage the bag in the region of the bag valve 6. After the vacuum has acted on the suction device 32 via the connection 33 and after the suction device arrangement 31 has been moved back briefly, the bag valve 6 is opened, as shown in FIG.
  • Carriage 20 drives up and thus transports the opened valve bag 1 to the filler neck 7 of the filling machine 8
