Definitions

  • the invention relates to a device for attaching a valve to a provided packaging, such as a packaging container or packaging material, according to the preamble of the main claim.
  • a device of this type known for example from DE-A-28 48 833, a composite tool consisting of a plunging tool and a pressure ram is arranged in a fixed position at one station of a packaging machine, to which packaging bags are fed one after the other.
  • the delivered valves adhering to a carrier tape are brought into succession by moving a guide piece with a peeling edge back and forth in alignment with the pressure stamp, if the coaxial plunging tool has previously pierced an opening in the wall of the bag provided. Since the performance of this known device is low, it is desirable to have performance adapted to higher, high-speed packaging machines.
  • the valve mounting device of the type mentioned according to the invention has the characterizing features of the main claim and has the advantage that the movement for positioning a valve on a packaging means is connected to the bringing in and out of working position of the locking tool by the common, movable support for the lock tool and the pressure ram.
  • the simply constructed and powerful device can also be combined in a simple manner with packaging machines of various types.
  • FIG. 1 shows a device for attaching valves assigned to a mandrel of a packaging machine, in plan view
  • FIG. 2 shows a part of the device according to FIG. 1 in a second working position in plan view
  • FIG. 3 shows a pressure ram in cross section
  • FIG. 4 shows an attracting tool in side view.
  • a segment-shaped support 12 is pivotally mounted about a pivot point 13. It is articulated on the piston rod 14 of a pressure-actuated working cylinder 15 which pivots it cyclically between two end positions.
  • Two other pressure-actuated working cylinders 16, 17 sit on the carrier side by side at a certain distance.
  • the piston rod 18 of the one working cylinder 16 carries a piercing or locking tool in the form of a needle 19 with a wedge-shaped tip 20.
  • the piston rod 21 of the other working cylinder 17 carries a pressure stamp 22 with a suction device in its end face.
  • the suction device is formed by an opening 23 which can be connected to a vacuum source via a line 24 and a valve (not shown).
  • a light barrier consisting of light source 36 and photocell 37 monitors the advance of a valve 1 in the region of the deflection edge 32 of the guide piece 31.
  • the guide piece 31 is arranged on the base plate 11 in such a way that the transfer point for the valve 1 peeling off from the carrier tape 3 at the deflecting edge 32 lies in alignment with the pressure plunger 22 when the carrier 12 with the working cylinders 16, 17 in its one, left end position is pivoted.
  • the needle 19 is in register with a packaging bag 4 made of a flexible packaging material, which is formed on a mandrel 38 and is provided for attaching a valve 1.
  • the mandrel 38 has a recess 39 for receiving the needle 19.
  • the pressure plunger 22 is advanced from its retracted position, whereupon the valve 1, which only partially adheres to the carrier tape 3, is pulled by the suction action of the pressure temple 22 against its end face and held there.
  • This transfer takes place in the one, left end position of the carrier 12.
  • the needle 19 is pushed forward simultaneously by the working cylinder 16, so that it cuts a gas passage opening in the form of an arcuate slot 5 in the hives 4 provided on the mandrel 38.
  • the working cylinder 15 pivots the carrier 12 into the other, right position, in which the plunger 22 is now in register with the provided booty 4, in particular with the slot 5 previously cut into it .
  • the working cylinder 17 In this position, the working cylinder 17 in turn pushes the pressure plunger 22 so that it presses the valve 1 held onto the wall of the bag 4 above the slot 5. After the suction line 24 has been disconnected from the vacuum source, the working cylinder 17 pulls back the plunger 22 ′ and the working cylinder 15 swivels the carrier back into the first position. At the same time, the bag 4 provided with a valve 1 is conveyed further and another is provided. In the meantime, the pair of preferred rollers 33, 34 has brought the valve 1 following on the carrier belt 3 into the take-over position, so that a new working cycle can proceed as described above.
  • the device described is assigned to a packaging machine on which hives are produced from flexible packaging materials, which are then filled and sealed. It can also be used in particular on so-called tubular bag machines. Furthermore, it can be combined with a conveyor device on which packaging material webs or blanks are fed, which are then shaped into packaging containers.
  • the attachment point of the valves to the bags or packaging is additionally assigned a liquid metering and supply device which applies the smallest liquid droplets to the opening of the valve.
  • the liquid is drawn into the valves by capillary action.
  • Such a device can also be arranged at another station through which the bags equipped with a valve run.
