Definitions

  • the invention relates to a device for aligning a Wicketer stacking station with respect to the edge of a plastic tube or semi-tubular web, in which the Wicketer stacking station consists of a longitudinally displaceable winder frame with transport arms rotating about a shaft for taking over welded welded from the plastic tube or semi-tubular web Bags, a longitudinally displaceable end frame on a base frame, which is connected to the winder frame via a carrier, and a stacking section running between the winder frame and the end frame and formed by an endless conveyor, which has intermittently driven traction means with pairs of stacking pins, onto which those provided with stamped-in positioning holes Bags are needled, the device having an adjusting device for moving the Wicketer stacking station according to a measured edge deviation and the wicking frame with at least one cross rail supported on rollers or sliding surfaces of a supporting frame.
  • So-called Wicketer stacking stations are usually placed behind plastic bags of plastic tubular or semi-tubular webs arranged by means of transverse welding separating welding stations arranged in such a way that these, with their transport arms arranged in pairs and equipped with suction devices or gripping devices, take over the bags and, after rotation by 180 °, stack them onto pairs of stacking pins of an endless conveyor of a stacking section.
  • these In order to be able to needle the individual bags for their stacking, they are provided with corresponding positioning holes which are punched into the still connected web before the welding station.
  • a Wicketer stacking station is known for example from GB-A-2 094 765. Alignment of the Wicketer stacking station with the web edge in the event of web delay is not described here, however.
  • the frame of a winding roller for winding a web is pivotally mounted on an intermediate plate which is guided on a base plate so that it can be moved, the frame being provided with a pivoting drive and the intermediate plate being provided with a drive for transverse displacement which scans over an edge of the web Sensors are controlled in such a way that the web runs straight on the winding.
  • the object of the invention is therefore to enable a simpler and more sensitive adaptation of the Wicketer stacking station with a stacking section to an offset of the web.
  • this object is achieved in a device of the type mentioned above in that the actuating device only acts on the wicket frame, that the end frame is supported on longitudinal rails of its base frame by rollers so that it can be rotated through small angles on the base frame so that the the winder frame with the end frame connecting carrier is designed to be rigid and that the winder frame is additionally connected to the end frame by a central girder of the stacking section.
  • the device according to the invention enables Fast and sensitive adjustment of the Wicketer stacking station including the stacking section to an offset of the web by running, since only the wicket frame is shifted by the amount of the offset.
  • the winder frame makes a slight rotation about a vertical axis, which is located in the area of the end frame, so that the desired adaptation to the web offset is achieved only by transverse displacement of the winder frame.
  • transverse displacement can take place by means of pressure-piston-cylinder units.
  • the transverse rail is expediently provided with a toothed rack with which a pinion driven by a stepping motor or the like meshes, the shaft of which is mounted on the support frame.
  • the support frame of the winder frame can be provided with rollers or wheels which are guided on rails of a base frame parallel to the stacking section.
  • the end frame is supported on longitudinal rails of its base frame by rollers, so that the Wicketer stacking station and the stacking section can easily be moved in the longitudinal direction for repair and maintenance purposes. During operation, however, the wicketer and end frames are locked relative to the base frame.
  • a shaft 4 which is provided with a drive (not shown), is mounted carries the transport arms 5 arranged in pairs and provided with suction devices or gripping devices.
  • the cross welding separating device 6 is arranged in front of the winder frame 3. This consists of the intermittently driven pair of transport rollers 7 for advancing the plastic tube or half tube web 10 by one bag width or length.
  • the welding tool consists of an upper, with a cutting edge, lifting and lowering welding bar 8 and a lower welding roller 9, which forms the counter jaws.
  • the sensing device 11 is arranged in front of the transport rollers 7 for scanning a side edge of the web.
  • a punching device is arranged in front of the sensing device and punches the positioning holes in the edge of the web at the intended distance from the side edge, the distance of which corresponds to the distance between the stacking pin pairs 12, 13.
  • the stacking pin pairs 12, 13 are arranged on plates of an endless conveyor chain or a toothed belt 14, which rotate over the front deflection wheel 15, which is mounted in the winder frame 3, and the rear deflection wheel 16, which is supported in the end frame 17.
  • the wicket frame 3 is connected to the end frame 17 by a longitudinally rigid support 18. Furthermore, a center girder 19 of the stacking section is connected both to the winder frame 3 and to the end frame 17, so that a further stiffening connection is created between the two frames.
  • the lower edges of the cross members 20, 21 connecting the side parts 1, 2 of the winder frame 3 form cross rails which are supported on the cylindrical shells of rollers 23 which are rotatably mounted on cross bars of a support frame 22 about horizontal axes parallel to the stacking section.
  • the support frame 22 is further provided with rollers 27 which are rotatably mounted about transverse axes and are guided on rails 28 of a base frame 29 running parallel to the stacking section.
  • the end frame 17 is provided with four rollers 30 mounted about transverse axes, which are guided on rails 31 of its base frame 32 running parallel to the stacking section.
  • the deflection wheel 16 mounted in the end frame 17 is provided with an intermittent drive 33 for the stacking belt provided with the stacking pins 12, 13.
  • the stepping motor is switched on in accordance with this offset via a control device, not shown, so that the winder frame 3 is adjusted via the pinion 25 via the measured offset.
  • the punching device for punching the positioning holes is also adjusted by a device, also not shown, so that the distance between the positioning holes and the edge of the web 10 remains the same.
