Definitions

  • the invention relates to an ultrasonic welding apparatus for forming welds on textiles according to the preamble of patent claim 1.
  • An object of the present invention is to develop an ultrasonic welding device of the type mentioned in such a way that welds of optimal uniformity can be generated.
  • the energy input on the sonotrode is distributed over an arc of about 30 °.
  • the same result can be achieved with substantially less energy in such a constructed ultrasonic welding device.
  • Particularly advantageous has proved to be an anvil circulating around at least two pulleys V-belt. If the V-belt is guided around three pulleys, two of which are equidistant from a working surface and the third over, good supervision can be achieved on the welding point while working.
  • the sonotrode may be stationarily arranged stationary or also movable, in particular pivotable. Furthermore, the sonotrode is preferably disk-shaped (angular or round disk shape) or spherically round, e.g. roll-shaped or spherical.
  • Figure shows a side view of a schematically illustrated ultrasonic welding device, which is installed in a work table.
  • reference numeral 1 denotes an inventive ultrasonic welding device, which is arranged in a recess 3 in a work table 5.
  • the ultrasonic welding device 1 comprises a disk-shaped sonotrode 7 according to this exemplary embodiment, which is excited by a suitable sound generator 9 known from the prior art (shown schematically as a rectangle).
  • a sonotrode 7 is generally understood a component which forwards the ultrasonic vibrations generated by the sound generator 9 to a workpiece to be sonicated.
  • the vertex S of the sonotrode 7 projects beyond the surface 11 of the work table 5 by an amount a.

  • Pulleys 13, 15, 17 carry a belt 21 which by unspecified
  • the sonotrode 7 is also drivable (shown schematically) by a motor M 2 - Depending on the distance between the two pulleys 13 and 15 and the distance a, with the sonotrode 7, the surface 11 of the work table 5 surmounted, wraps around the lower run 19 between the two pulleys 13, 15 the apex region of the sonotrode 7 at a larger or smaller angle ⁇ .
  • the wrap angle ie the angle over which the belt 21 rests on the periphery of the sonotrode 7, is approximately 30 °.
  • the speed of the two drive motors M 1 and M 2 is individually adjustable and adjustable, so that between the two contacting parts of the sonotrode 7 and the belt 21 and a minimum differential speed (ni - n 2 ) can be driven to compensate for Lengths of the surfaces of a workpiece 23, which is guided over the disc-shaped sonotrode 7, compensate.

Abstract

L'invention concerne un dispositif de soudage par ultrasons (1) destiné à former des cordons de soudure sur des textiles, comportant une sonotrode (7) et une enclume (8) réalisée en matériau élastique. L'enclume peut se présenter sous la forme d'au moins une courroie (21) guidée sur deux poulies (13, 15). Une partie (19) de la courroie (21) entre en contact avec la périphérie de la sonotrode (7) à un angle (a) et bloque dans cette zone la pièce intercalée lors du soudage.
