Definitions

  • the invention relates to a system for producing strapped wire mesh rolls, with a winding device which has a driven winding mandrel for winding the supplied wire mesh and a guide device for threading the wire mesh into the winding mandrel, a stripping device with which the wound wire mesh roll relative to the winding mandrel in the axial direction is movable, a gripper mechanism which has gripping arms which can be pivoted from above and from below against the lateral surface of the wire mesh roll and by means of a transport device from a first position in which it picks up the wire mesh roll in the region of the winding device by means of the gripping arms, over a length exceeding the roll length Distance in the direction of the winding mandrel axis in a second position distant from the winding mandrel, and a strapping device for the wound wire mesh roll with a strapping frame for a strapping element.
  • a system known from AT-PS 276.028 of the type specified in the introduction has the disadvantage that the gripper mechanism can only be moved passively from the first to the second position with the aid of an ejection plate, in which a stationary strapping device is provided. It is therefore not possible for the strapping device to work sensitively and to adapt it to different mesh roll dimensions or strapping requirements.
  • the object of the invention is to avoid this disadvantage and to create a system of the type specified in the introduction with which the wire mesh roll can be tied with great accuracy at any point along the length of the wire mesh roll using strapping elements.
  • the device according to the invention has the features that the gripper mechanism has at least two mutually independent units of gripper arms provided with associated holders and by means of a gripper mechanism load-bearing, in a known manner movable carriage on rails parallel to the mandrel axis is adjustable in freely selectable positions, and that the strapping frame adjustable in a known manner perpendicular to the mandrel axis is also mounted on a trolley and controlled with this carriage parallel to the mandrel axis on rails can be moved into freely selectable strapping positions, the gripping arms of each gripping arm unit being able to be pivoted away from the wire mesh roller in a controlled manner for passing through the strapping frame.
  • the holders of the gripper arm units are formed by bearing plates oriented transversely to the mandrel axis and adjustable relative to one another in the direction of this axis, which are mounted on the carriage of the gripper mechanism and on which the pivot bearings for the gripper arms are provided above and below the mandrel axis .
  • the free ends of the gripping arms preferably engage the wire reel via holding members that run parallel to the winding mandrel axis and are preferably adjustable in the direction parallel to this axis. This design ensures that wire mesh rolls of different diameters are held safely and gently.
  • a mesh web G is fed in the direction of arrow P 1 with the aid of driven transport and retention rollers 1 and between a pair of guide rollers 2 of a winding device 3, which is only shown schematically.
  • the winding device 3 has a not shown drive and drive devices according to the double arrow P2 drivable mandrel 4 and an upper guide plate 5 and a lower guide plate 6, which are each pivotable towards and away from each other according to the double arrow P3.
  • the guide plates 5, 6 are pivoted against one another and form a guide passage, via which the initial section of the grid path is guided exactly onto the winding mandrel 4, which facilitates the threading and fixing of the grid path on the winding mandrel 4.
  • the length of the grid web G is continuously measured with the aid of a length measuring device 7 assigned to the transport and retention rollers 1.
  • the grid web is cut with the aid of a cutting device 8 connected downstream of the measuring device, which essentially consists of an upper shear bar 9 provided with a knife 11 and a lower shear bar 10 also provided with a knife; separated from the material stock.
  • a labeling device 12 is provided which, when the lower guide plate 6 is pivoted downward away from the wire mesh, through a cutout 15 of the guide plate 6 around a suspension 13 from an initial position 12 'in accordance with the double arrow P4 into a tangent to the winding mandrel 4-pointing working position 12 '' is pivotable, in which the labeling device 12 essentially touches the underside of the grid web.
  • labels E which contain, for example, product data, are continuously wrapped in the grid roll R '.
  • the labels E are taken from a label supply magazine 14 and can be separated from a material supply as required or can also be in the form of single sheets.
  • the labeling device 12 is adjustable within the cutout 15 of the lower guide plate 6 according to the double arrow P5 parallel to the mandrel axis xx in order to adapt the position of the labeling device 12 to different widths of the grid web to be wound up and to be able to adjust the position of the wrapped label E relative to the edge of the grid web .
  • the lower guide plate 6 has a second cutout 15 'which can accommodate a second labeling device (not shown).
  • a transport carriage 16 can be moved according to the double arrow P6 parallel to the direction of the mandrel axis x-x on rails 17 from a take-over position W, in which the carriage takes over the grid roller R 'from the winding device 3, into a binding position A.
  • the transport carriage 16 carries a plurality of bearing plates 18 oriented transversely to the longitudinal direction of the carriage, on each of which three gripping arms 19, 20, 21 forming a gripping arm unit are pivotably mounted according to the double arrow P7 about axes parallel to the mandrel axis x-x.
  • the end shields 18 are adjustable relative to one another in accordance with the double arrow P8 parallel to the mandrel axis x-x in order to be able to adapt the relative position of the gripping arms to the length of the grid roller R 'to be accommodated. Shortly before separating the grid web from the material supply, the gripping arms are placed on the grid roll R ', the contact pressure being adjusted so that the separated end of the grid web can be wound up without damaging the grid roll R'.
  • each gripper arm that engages the grating roller R ′ has a tubular holding member 22 that is parallel to the winding mandrel axis at the free end of the gripper arm slidably attached and its length and design is adapted to the mesh size of the grid roller to be held.
  • the three arms of each gripper arm unit are mounted on the associated end plate 18 so that the bearings of two arms 20, 21 lie above the mandrel axis xx, while the bearing of an arm 19 is below the mandrel axis.
  • the grating roller R ' is supported by the gripping arms 19, 20 from below, whereas the gripping arm 21 holds down the grating roller R' from above.
  • the gripper arms 19, 20, 21 of a gripper arm unit can be pivoted individually or together with the aid of actuating elements (not shown).
  • the grid roller R' is taken along by the transport carriage and at the same time by means of an adjustable opening on the rails 17 by means of a double arrow P9 parallel to the mandrel axis xx on the running rails 17 the stripping carriage 23 having the mandrel 4 is pushed off the mandrel 4.
  • the grid roller R ' is transported by means of the transport carriage 16 from the take-over position W to the binding position A, which lies in the axial direction so far outside of the winding device 3 that the grid roller R' completely releases the winding mandrel 4.
  • the winding device 3 is immediately ready for winding up a new grid roll.
  • the winding mandrel 4 can be turned back against the original winding direction.
  • a strapping device 24 is provided for tying a grid roller R in the tying position A.

From stand 27 protrudes a strapping frame 28, which surrounds the lattice roll R to be tied and places a strapping band B lying in the strapping frame 28 in the form of a loop B 'around the lattice roll R.
  • the strapping B can have different shapes within the scope of the invention and can consist of a wide variety of materials, such as plastic or metal straps.
  • elements for strapping such as a storage magazine for the strapping, a sealing unit and a cutting device for the strapping are accommodated.
  • the strapping device 24 is brought according to the double arrow P1 Gitter parallel to the longitudinal axis of the lattice roll R to be tied to a point at which the strapping B is to be placed around the lattice roll R. Then the stand 27 is moved so far against the grid roller R according to the double arrow P11 that the stand-side inside of the strapping frame 28 is exactly against the grid roller R. The loop B 'of the strapping is pulled shut, closed at the point of closure and the strapping is then separated from the material supply. Then the stand 27 moves back to its starting position according to the double arrow P11.
  • the strapping device 24 is adjusted with the help of the carriage 26 according to the double arrow P10 along the fixed transport carriage 16 and thus along the lattice roll R and positioned at a new location.
