Definitions

  • the invention relates to a method for decorating objects having a conical outer surface with a decor of an embossing film, the embossing film, which is provided in succession with a large number of decors, being unwound from a supply roll and fed to an embossing station which receives the respective object to be decorated, in which the decor is provided by the Embossing foil is transferred to the conical outer surface of the object to be decorated, the embossing foil around an adjustment device in the feed direction of the embossing foil upstream of the embossing station Arranged deflection roller is deflected, which together with the supply roll for the embossing foil with the aid of the adjusting device executes a movement parallel to the axis of the embossing roller and at the same time a pivoting movement about a pivot axis perpendicular to its longitudinal axis, and a device for carrying out the method.
  • Such a method or a device for performing this method is known from DE-AS 27 21 980.
  • the aim is to decorate a truncated pyramid-shaped surface of an object, which is, for example, a television housing, by means of an embossing foil.
  • the supply roll can be moved axially and approximately parallel to the embossing roller of the embossing station.
  • the embossing film is mounted between the supply roll and the embossing roller before it lies against the jacket partial surface of the object to be decorated via a transverse axis which is displaceable approximately parallel to itself for tensioning the embossing film and rotates about a transverse axis running perpendicular to the jacket partial surface of the article to be decorated.
  • the stamping foil is guided around a dancer roll, which is movable with the supply roll for the stamping foil.
  • a so-called dancer roller as a deflection roller, i.e. a roller that is freely movable and that suits the respective one through the stamping foil or the respective partial shell surface adapts subject-specific conditions step by step.
  • the situation is different, however, with objects having a conical lateral surface are frustoconical. Such objects are, for example, cans or the like.
  • the invention has for its object to provide a method of the type mentioned and a device for performing this method, with which it is possible easily and within relatively short cycle times, a conical, i.e. to decorate objects with a truncated cone-shaped surface.
  • This object is achieved according to the method in that the deflection roller is continuously shifted linearly by a distance that corresponds to the deviation between the straight course of the embossing foil and the curve of the development of the conical outer surface of the object to be decorated, and in that the deflection roller simultaneously continuously by an angle is pivoted so that the rectilinear course of the embossing film is compensated in relation to the respective opening angle of the arcuate development of the conical outer surface of the object to be decorated.
  • the deflection roller and with it the supply roll for the stamping foil accordingly lead in two degrees of freedom, that is, along its linear adjustment path and in the area of it Pivoting angle precisely coordinated forced movements. It is therefore not possible to speak of a so-called dancer role, as described in DE-AS 27 21 980 mentioned at the beginning.
  • the deflecting roller is accordingly rotatably mounted on a bearing part about its longitudinal axis.
  • This bearing part is also intended for storing the supply roll for the stamping foil.
  • a movement of the bearing part therefore requires not only a movement of the deflection roller, but a simultaneous movement of the supply roll for the stamping foil.
  • the bearing part is connected to the adjustment platform by means of a swivel axis.
  • the pivot axis between the bearing part and the adjustment platform is oriented to the embossing station in such a way that a possible warping of the embossing foil which has been unwound from the supply roll, deflected on the deflecting roller and then fed to the embossing station is minimized.
  • the adjustment platform is arranged in a linearly movable manner on the stationary base part, the linear mobility of the adjustment platform and thus the linear movement of the bearing part or the deflection roller mounted on the bearing part to compensate for the linear course of the embossing foil in relation to the curve of the development of the conical outer surface of the decoration Object serves.
  • each linear movement of the adjustment platform and thus simultaneously the bearing part or its feeler element results in a relative movement with respect to the stationary guide device provided on the stationary base part , whereby each linear movement of the adjustment platform simultaneously causes a pivoting movement of the bearing part and thus the deflection roller about its axis of rotation, which to compensate for the rectilinear course of the stamping foil in relation to the respective opening angle of the arcuate development of the conical outer surface of the to be decorated Object serves.
  • the deflection roller accordingly executes in its two possible degrees of freedom, that is to say translationally in its longitudinal direction and rotationally about its axis of rotation, precisely adapted to the object to be decorated.
  • the drive device provided for linear movement of the deflection roller can have a disk which can be driven about its central axis, is rotatably mounted on the base part and is provided with a spiral groove, which engages one leg of an angle lever mounted on the base part, and with the second leg of the Angle lever can be articulated at a connection point a connecting element which is pivotally attached to the adjustment platform.
  • the drive device for the disk having a spiral-shaped groove is preferably a drive with which the embossing roller of the embossing station and other components of the device are also driven.
  • the connecting element has a variable length. This makes it possible, as desired, to precisely adapt the forced movement of the deflection roller in its two degrees of freedom mentioned to each object to be decorated with a conical outer surface in terms of dimensions and conicity. It serves the same purpose if the distance from the connection point of the connection element to the axis of rotation of the angle lever and / or if the fastening point of the connection element on the adjustable platform can be changed.
  • the guide device associated with the feeler element and provided on the stationary base part can have a curve element on which the feeler element is guided so as to be slidable, the curve element being oriented in a direction different from the direction of the linear movement of the adjustment platform.
  • the Guide device is arranged adjustable on the base part. This also makes it possible to adjust the linear movement and the pivoting movement of the deflection roller in relation to the embossing station, ie in relation to the object to be decorated with a conical outer surface, to the dimensions and conicity of the object to be decorated, in order to fit objects with the decor of an embossing foil to provide.
  • Reference number 12 shows the development of the conical, ie the frustoconical, surface of an object to be decorated with the decor of the embossing film 10.
  • the development 12 of the outer surface of the object to be decorated has an outer arch 14, an inner arch 16 and side edges 18 and 20. Any surface line of the development 12 of the outer surface is designated by the reference number 22.
  • the surface line 22 includes an opening angle b with the first side edge 18.
  • the intersection 24 of the surface line 22 with the outer curve 14 of the development 12 of the surface of the object to be decorated is at a distance a from one edge 26 of the embossing film 10 or its decoration.
  • the opening angle b and the distance a depends on the dimensions and the taper of the object to be decorated and its development 12.
  • the arrow 28 indicates the direction of rotation of the object to be decorated, ie the movement of its development 12 and the arrow 30 indicates the simultaneous feed movement of the embossing film 10 with its decor.
  • the embossing film 10 must adapt to the rotary movement of the truncated cone-shaped object to perform a linear movement corresponding to the respective distance a and at the same time a pivoting movement corresponding to the opening angle b associated with each distance a to ensure an exact adaptation of the embossing foil 10 with its decor to the conical object to be decorated. How this adaptation between the linear movement and the pivoting movement of the embossing film 10 is realized is described in the following with reference to the schematic illustration. Fig. 2 and explained with reference to a preferred embodiment of the device, as illustrated in Figures 3 to 7.
  • FIG. 2 shows a schematic, greatly reduced illustration in a view from above of an object 32 to be decorated, which has a frustoconical outer circumferential surface 34 which is to be decorated with a pattern of an embossing film 10 in a precisely fitting manner.
