Definitions

  • the invention relates to a device for connecting the Umschnürungsbandenden on strapping machines, with a strapping band guide and a clamping and connecting station for the strapping band, wherein arranged in the connection station clamping and closing stamp are by means of springs against a the clamping and closing stamp biased in a working and release position moving camshaft are.
  • a device of the type in question is known from US 4,776,905, wherein the Umschnürungsband consists of meltable plastic material. After putting the strapping band around the package and Stramm convinced the Umschnürungsbandes be clamped, superimposed Umstrürungsbandenden directed to the longitudinal extension vibratory transverse movements generated on these, due to friction to heating the respective Umschnürungsband Schemee, after which then the connection of the melted over the closing punch Band ranges done. On the control of the clamping and closing stamp through the camshaft is not discussed in detail in this patent.
  • DE 4014305 A1 is also known from the prior art. These known device has a camshaft, by means of which, about Levers controlled by rams. additionally are provided springs which depress the plunger.
  • EP 0720948 A1 discloses a strapping machine for packaged goods, which also plunger by means of a lever through a camshaft are charged. Clamping and closing punches are not (both) against the camshaft is biased.
  • the invention is the Task is based, a device of the type in question in terms their structure and their operation advantageous embody.
  • This task is initially and essentially at a device having the features of claim 1 solved, taking care that the springs Compression springs are and the camshaft in a middle Area of clamping and sealing stamp attacks.
  • This configuration is a favorable force attack the camshaft on both the clamping and sealing stamp in front.
  • the stamp Upon loading the stamp by compression springs, the stamp are hiring free guided. Otherwise, the admission is carried out by the compression springs such that the punch in the direction their working position are moved.
  • a structurally favorable Design is shown by the fact that two clamping punch and an interposed seal are provided. They preferably extend in a parallel juxtaposition and create the Prerequisite for a favorable control. installation Technical Benefits arise from the fact that the stamp removable without further fasteners behind a cover plate are arranged.
  • the camshaft with respect to the cover plate is arranged on the opposite side.
  • the stamps are these through in windows the stamp stored roles led, which is also a largely play-free storage allowed.
  • this stamp designed so that it has a boom on the foot side for bearing one acted upon by the camshaft Caster.
  • the stamp itself possesses an L-shape, with the longer leg the actual Stamp and the shorter leg of the boom represents, which with the roller the camshaft engages behind.
  • the invention provides in that the closure punch has a direction transverse to its direction of movement displaceable friction slide stores.
  • This receives after completing the Umschnürungsbandes and tightening the same Ribbon section of the strapping band its vibration-like Transverse displacement associated with heating the superimposed band areas by friction.
  • an upward shift takes place the locking punch, wherein the friction slide and the required pressure load on the melted Band ranges exercises.
  • the friction slide U-shaped takes in its U-interior Bearing elements of the closure stamp on. The movements let the closure stamp and the friction slide coordinate favorably and lead to one functionally favorable construction of the closure stamp with friction slide.
  • the friction slide itself are the bearing elements designed as bearing rollers.
  • the Umschnürungsband opposite to the drive wheel interacts with a mating gear. This represents an abutment, so that an optimized Transport of the strap by the Umschnürungsbandkanal is realized. It makes sense also to drive the mating wheel. It affects the band of strapping but not just propulsion, but also withdrawal forces. For this serves a the Umschnürungsband tensioning wheel which can be driven in the clamping direction. In known Way, this is disengageable, so it in particular only runs with a pre-transport. Only in Clamping cycle, the tensioning wheel is coupled. For the purpose of reduction the surface load of the tape has the Tensioning wheel a relatively large diameter.
  • An alternative is characterized by that the driving force by means of a gear on the Tensioning wheel is applied, with a counter-force received the transmission via a load cell and a certain admission of the load cell as a limit is used for the clamping force.
  • the driving force by means of a magnetic coupling on the tensioning wheel is transmitted.
  • the clamping force of such a coupling theoretically can be indefinite. she is easily variable, so infinitely adjustable in terms of on the flow behavior of the plastic Umschnürungsbandes. For one, such a coupling a Magnetic powder coupling be. On the other hand, too a hysteresis coupling can be used.
  • the transferable Moment is of the current in the exciter coil dependent and infinitely variable up to the respective maximum value adjustable.
  • the advantage of such a hysteresis coupling exists in a particularly high life expectancy, because the hysteresis clutches always have the torque create an air gap in contrast to Reibbelagkupplept and magnetic powder clutches. There are in this regard so no wear and no sealing problems, so that the life expectancy is a multiple of the corresponds to the aforementioned couplings. Also stands out Such a hysteresis clutch by a high torque repeatability out. Then it lies because no mechanical friction and also no magnetic powder for Drive transmission is used, a special gentle way of working.
  • Another advantageous feature of the invention is to be seen in that the friction slide between two Clamping dies is arranged. Before laying around the Plastic strapping band are these two Clamping punch including friction slide in one Release position, what the insertion of the strap and laying it around the package allows. Thereafter, the insertion-side clamping punch closes, so that the strapping tape taut around the package is tensionable. Then the second clamping punch moves in active connection. Time-delayed controls the seal with the friction stamp in his investment position to the strapping band. At the same time can over a the sealing punch associated cutting knife the Cutting the Umschnürungsbandes done.
  • Friction slides become the superimposed band sections by relative transverse displacement to each other heated, melted and after exposure of Reibschlitten-displacement welded.
