Definitions

  • the invention relates to a method for strapping a bale or the like, preferably from z. B. man-made fibers, by means of a metal bandage coming from a supply reel with its free end first passed through a metal connecting element held ready, then guided around the bale, the advanced free end guided a second time into the connecting element, locked, then by rearward Driving the bandage through the connecting element this bandage is stretched around the bale, the connecting element is pressed and the part of the bandage still connected to the supply reel is cut.
  • a method of this type is known from DE-B-1 257 662.
  • the band serving as a metal bandage behind and at a distance from the connecting element is gripped by a separate device and bent by a mandrel by 180 °. After removal of this bending device and subsequent tensioning of the band around the bale, the loop thus produced slips over the connecting element with which the two bands lying one above the other are pressed.
  • the connecting element is also a metal band, which is bent twice in a U-shape to produce an all-round clasp and then - but with an open seam - pressed. This method of closing the bandage is very complex to construct and the bandage itself is not very durable.
  • a more advantageous strapping method is known from EP-A-093 953.
  • the device disclosed there has the advantage that a permanent strapping of a fiber bale is made possible by means of a wire, the wire ends being connected to one another by a seal made of a tubular metal piece.
  • the object of the invention is to develop a method and a device for carrying out this method, with which a permanent, firm strapping of a bale or the like can be produced, which is made from a wire and as a binding closure from an all-round sealed seal, the bale can have any shape or dimensions, without the wire must be detachably gripped for tensioning the loop, and without the risk that the necessary wire section around the bale is previously cut too short or too long.
  • the invention provides that the bandage formed as a wire passes through a completely closed metal tube as a connecting element and a short piece of the free end of the wire, previously run around the bale, is bent for locking around the end of the metal tube.
  • the wire since the wire is only cut from the supply spool after the seal has been produced, the outer dimensions of the bale are irrelevant for the establishment of a permanent connection.
  • the wire does not need to be detachably gripped either for tensioning around the bale or for producing the seal, so that a holding and closing device of the known type can be dispensed with in the new method.
  • the bending of the end can be canceled again after straightening the seal by straightening the wire, so that possible injury to a person through the bent end or damage to the packaged goods can be avoided.
  • the fiber baling press shown in FIG. 1 for pressing a bale 1 consists of a press ram 2 and a counter pressure plate 3.
  • the four now free side surfaces of the bale 1 enclose a press jacket 4, which now closes the bale 1 after the pressing process has ended is withdrawn from the top of the bale 1.
  • the bale 1, which is free on four sides, held in the pressed state by the press die 2 and advantageously previously packaged on the six peripheral surfaces, is provided with a plurality of bandages by a lacing device 5 which stands to the right of the bale 1 and can be moved past the bale. that both the press ram and the counter pressure plate have 3 guide channels through which a wire can be inserted.
  • a rear device 6 is additionally detachably fastened, with which the wires initially threaded through the counterpressure plate 3 are automatically bent upwards and are guided back to the strapping device 5 by the ram 2 (dash-dotted line).
  • the strapping device 5 consists of a frame 7 which is arranged on the bale 1 so as to be movable on the floor and via a support 8 fastened to the press. This movability of the strapping device is important for the exemplary embodiment shown in order to be able to place several bandages around the bale held in the press with only one strapping device 5. It is also conceivable to move the bale past the strapping device or to arrange several such strapping devices next to one another, which then place the required bandages.
  • an arm 10 is held pivotably about the axis 9 at the level of the lower longitudinal edge of the bale 1 by means of a piston-cylinder unit 11. All details for placing the bandage around the bale and also for sealing are arranged on this arm 10.
  • the wire feeder 12 which consists of two pairs of rollers arranged one above the other, each of which grips the wire 30 in a ring groove between them and rotates both forwards and backwards (double arrow) by means of the motor 13 with gear 14.
  • the sealing and cutting device 15, which is described in detail in connection with FIG. 3, is arranged below the wire feed 12.
  • a guide arm 18 is held pivotably about the axis 16 by means of the pressure piston cylinder unit 17 in order to be able to guide the wire 30 "pushed back by the press ram 2 back to the metal tube holding device (FIG. 2).
  • the strapping of the bale 1 with a wire 30 takes place with this device as follows.
  • the wire 30 coming from the supply spool 19, which can also be arranged separately from the frame 7, is pushed by means of the wire feeder 12 through a metal tube 20 (FIG. 3) and then through the guide channels in the counter-pressure plate 3, in the rear device 6 and in the ram 2 back to the strapping device 5.
  • the wire 30 "automatically runs into the guide channel of the guide arm 18 and thus back to the metal tube 20 and through it again.
  • the tape feed 12 is switched off by a limit switch, and then the free one The wire end is locked on the metal tube 20 (see description of FIG.
  • the guide arm 18 is pivoted about the axis 16 into the dot-dash position by means of the drive 17 and finally the tape feed 12 is moved backwards for tensioning the wire 30 around the bale 1 , the wire 30 being pulled out of the guide channels on the three sides of the bale 1.
  • the arm 10 of the strapping device 5 is pivoted against the bale 1 with the aid of the drive 11, so that the wire 30 around the bale 1 comes to rest relatively firmly.
  • the sealing device according to FIG. 3 is then activated and the part of the wire 30 connected to the supply spool 19 is separated from the seal 20 '. Now the drive 11 can arm 10 of the Swing the strapping device 5 back into the position shown in FIG. 1, with which the strapping device 5 can move past the bale 1 parallel to a further strapping plane.
  • FIGS. 2 and 3 show the details of the sealing and cutting device 15 according to FIG. 1.
  • the metal tube holding device according to FIG. 2 essentially consists of an arm 23 which is held on the device part 15 so as to be pivotable about the axis 22 and which can be pivoted outwards by 90 ° from its working position shown in FIG. 2 with the aid of the pressure piston cylinder unit 36.
  • the arm 23 pivots with the aid of the drive 36 into the position shown in dash-dot lines, so that the metal tube 20 can now be pressed into the seal 20 'according to FIG. 3 without impairing the holding fingers 24.
  • a new metal tube is now pushed into the holding fingers 24 from the magazine 26 with the aid of the drive 25, so that the opened press jaws 27, 28 according to FIG. 3 can be re-equipped with a metal tube 20.
  • the metal tube pressing device according to FIG. 3 for producing a seal 20 ' consists of two pressing jaws 27, 28, of which the one designated 27 is arranged in a stationary manner.
  • the pressing jaw 28, on the other hand, moves towards the pressing jaw 27 in the direction of the arrow 29 to produce the seal 20 '.
  • the wire 30 coming from the supply spool 19 is pulled through the metal tube 20 held by the holding fingers 24 between the press jaws 27 and 28.
  • the wire 30 On the exit side of the metal tube 20, the wire 30 'leaves the metal tube pressing device and then wraps around the bale 1 according to FIG. 1 in the manner described there.
  • the slider 31 moves in the direction of the arrow 32 into the position shown in dash-dotted lines, so that the end of the wire 30 "protruding from the metal tube 20" is bent in the direction of the arrow 32.
  • the wire 30 is thus at its end on the metal tube 20 locked, so that the wire feed 12 can now be driven in the opposite direction in order to achieve the tensioning of the wire 30 around the bale 1.
  • the metal tube pressing device lies close to the bale 1, as shown in FIG. 3.
  • the press jaw 28 now moves in the direction of the arrow 29 into the position shown in dash-dot lines, so that a permanent connection is now established between the two wire ends 30' and 30 ".
  • the wire 30 ' is still connected to the supply spool 19.
  • the separation process takes place at the same time, but for safety reasons, with the manufacture of the seal 20 '.
  • two cutting plungers 33, 34 are arranged facing each other at the input of the pressing device according to FIG. 3.
  • the cutting plungers 33, 34 also move towards one another and separate the wire 30 'from the supply spool 19.
  • the slide 31 moves back in the direction of the arrow 35 into that shown in solid lines Position so that the end of the wire 30 "is bent straight again.
