Definitions

  • the invention relates to a device for clamping and closing of strapping bands, in particular bands made of plastic, for PackungsumreifInstitut, with a superimposed band ends of the strapping band receiving, on a longitudinal outside and the front and rear end faces substantially open band channel, on its longitudinal inner side a band edge guide for the inner edges of the strapping has, with a arranged in the front region of the device, when clamping in the band channel partially bordering, acting on one of the two belt ends tensioner and with a clamping direction behind arranged Bandverschuch affection.
  • Devices of this type are used to strapping packages such as large cartons or loaded pallets and thus to hold the palletized goods or cartons together and secure them for transport.
  • a solid band usually made of plastic, placed around the package, the band ends are braced against each other by means of the device and then connected together.
  • the connection generally takes place with the aid of a friction welding device forming the closing device.
  • the object of the invention is to avoid these disadvantages and to design a device of the type mentioned above so that the strained against each band ends even without band edge guide on the longitudinal outside of the band channel in the closing device are largely without offset one above the other.
  • band edge guide obliquely on the longitudinal inner side of the band channel extends to the clamping direction of the tension roller in the direction of the longitudinal outer side of the band channel.
  • the inner band edge guide thus does not extend parallel to the clamping direction of the tension roller and thus not at right angles to its axis, but is slightly obliquely set to the clamping direction, whereby it is substantially parallel to the position of acted upon by the tension roller (upper) band end during the tensioning process , Since the second (lower) end of the tape also bears against the tape guide arranged at an angle to the tensioning roller, it is in the same alignment as the first, tensioned tape end in the region of the closing device and is thus connected to it over its entire width.
  • the superposed bands are thus aligned obliquely to the clamping direction that is generated by the tensioning wheel on the exciting (upper) band during the transport and tensioning operation acting on the longitudinal inner side of the band channel force component, the running of the free band to the outer side of the band channel due to compensated by the tension roller caused band deformation.
  • An additional, outer band edge guide in the area of the band closing device can be dispensed with completely.
  • the band edge guide is formed substantially by a front edge stop located near the tension pulley and a rear edge stop near the belt closing means, the rear edge stop protruding further toward the longitudinal outside in the band channel than the front edge stop.
  • the band ends are thus only there a guide their inner edges, where it depends on their location particularly, namely in particular in the field of closing and on the tensioner.
  • the band edge guide is suitably aligned at an angle of 1 ° to 6 ° obliquely to the clamping direction of the tension roller, which corresponds to the angle to the free end of the tape - depending on the type of strip material used and the size of the pressing force of the tensioner - relative to the tangential or Clamping direction of the tension roller is directed towards the limited by the band edge guide longitudinal inner side of the band channel.
  • the band edge guide can be adjustable in its angular position relative to the clamping direction, whereby it is possible to adapt the device to the extent of compensating band end deflection.
  • the band edge guide transversely to the clamping direction in order to take into account the different widths of the strapping bands used, if this is desired in individual cases.
  • the front and / or rear edge stopper is adjustable transversely to the clamping direction of the tensioning roller, whereby on the one hand, the angular position of the band edge guide, on the other hand, the effective width of the band channel can be varied.
  • the band channel can be closed in its front region in the vicinity of the tensioning roller with an outer band stop, which can be lowered together with the tension roller and so unintentional leakage of the band laterally from the band channel prevented during transport and tensioning by the tension roller.
  • the designated in the drawing in its entirety by 10 device is used to produce a strapping 11 for a package 12 by means of a strapping made of plastic, which is placed around the package and the two band ends 13,14 clamped by means of the device against each other and then welded together ,
  • the device has an extending in the longitudinal direction, on a longitudinal outer side 15 and the front and rear end faces 16,17 open band channel 18, which is bounded below by a pressure plate 19 and in the top of a tension roller 20 a clamping device 21 together with a front, outer band stop 36 is adjustable.
  • the band channel the band ends are inserted from the longitudinal outer side 15 of the channel to produce the strapping.
  • the tension roller 20 and the outer band stop 36 are pivoted after inserting the band ends 13, 14 in the band channel 18 down, whereby the outer band stop 36 prevents re-emergence of the band from the channel.
  • the tensioning roller presses firmly during the tensioning operation on the upper end of the tape 13 and pulls this in the tensioning direction 22 over the lower end of the tape 14 until the desired tape tension is reached.
  • a arranged in the tensioning direction 22 behind the tension roller closing device with Reibsch practiciser 24 moves the upper end of the tape at high speed over the lower end of the tape back and forth, so that the two band ends weld together due to the resulting frictional heat.
  • the operation of such devices is known, so that should be dispensed with a detailed description here.
  • the tension roller 20 is mounted in the housing 25 of the device flying with a roller bearing 26 and protrudes from the belt channel 18 inside limiting longitudinal inner side 27 in this.
  • a roller bearing 26 In order to clamp the upper end of the tape 13 with the desired high tensile force, it is necessary to press the tension roller 20 by means of a non-illustrated adjusting mechanism with great force on the strapping.
  • the device according to the invention in the rear direction of the band channel in the tensioning direction only comes with a band edge guide 30 arranged on the longitudinal inner side 27 in order to compensate for the negative effect of the uneven compression of the upper band end during tensioning.
  • the band edge guide 30, which consists in the embodiment substantially of a front, near the tension roller 20 arranged edge stopper 31 and a rear edge stop 32 in the vicinity of the Reibsch thoroughlyiser obliquely to the clamping direction 22 of the tension roller 20 at an angle ⁇ of about 3 ° arranged, ie the rear edge stop protrudes further in the direction of the longitudinal outer side 15 in the band channel 18 than the front edge stop.
  • the band edge guide 30 formed by the two edge stops ensures that the two band ends 13, 14 in the band channel 18 are not approximately parallel to the tensioning direction 22 of the tensioning roller, but extend at an angle ⁇ obliquely to the tensioning direction, which corresponds at least approximately to the angle to the the upper end of the band 13 is deflected during the clamping process as a result of the non-uniform pressure forces over the bandwidth.
  • the two belt ends are thus in the inlet region 33 in the tensioning direction 22 in front of the tensioning roller 20 as far as possible over each other edge-to-edge, as can be seen in Fig. 3, and are aligned in the closing device 23 with each other. They are therefore superimposed with the friction welding unit edge-to-edge welded together, so that the weld receives the highest possible strength.
  • the rear edge stop 32 is arranged transversely to the clamping direction 22 adjustable in the housing 25, as indicated by the double arrow 35. This makes it possible to change the angle ⁇ , by which the band edge guide 30 is inclined relative to the clamping direction 22. This can be taken into account the fact that the amount of compression of the upper end of the tape and thus the deflection of strip material changed to strip material and in dependence on the applied Antik practitionern.
  • the invention is not limited to the illustrated and described embodiment, but various changes and additions are conceivable without departing from the scope of the invention. So it is easily possible to make the front edge stop adjustable transverse to the clamping direction.
  • the band edge guide can for example also consist of a continuous guide rail which extends substantially from the front to the rear end of the pressure plate.
