Definitions

  • the invention relates to a thread processing machine, in particular an embroidery machine according to the preamble of claim 1.
  • the thread changing devices on embroidery machines are used to change colors, i.e. to be able to use threads of different colors and possibly also of different types one after the other.
  • Known embroidery machines in particular small embroidery machines, have as many needle bars for this as there are colors to be used, i.e. For each different thread there is a separate needle bar with needle, thread layer and thread tensioner, which can be used one after the other.
  • Such solutions are structurally extremely complex.
  • the number of threads of different colors is limited. In practice, the limit for the number of needle bars and thus for the number of colors that can be used is 9 to 10. If more colors and thus more needle bars are to be used, the mechanical outlay is greater and in particular the construction effort is greater and the embroidery head is thus wider .
  • a thread changing device is known from WO-A-9 104 217, which can have a splicer as the thread connecting device.
  • a frame is provided in which thread clamps and thread guide tubes are arranged, through which the threads available for selection are guided.
  • a movable carriage is arranged in front of it.
  • the invention has for its object to provide a machine of the generic type that greatly reduces the mechanical effort for color change-related thread changes and that has no practical limitation on the number of colors that can be used.
  • the invention provides that the thread in use is connected to the beginning of the following thread of a different color by air swirling, and that the leading thread is used to pull the subsequent thread through the needle, which is possible because there are no knots or the like occur.
  • This section produced by air swirling, in which the two threads are connected to one another, can be tightened by the thread tensioner, the eyelet of the thread layer and in particular the eyelet of the needle are pulled through.
  • the leading thread which is to be replaced by a subsequent thread of a different color, is cut off immediately after the connection has been made. This can theoretically be done by hand, but expediently through the advantageous further development according to claim 2.
  • the section in which the leading and the subsequent thread are connected to one another by air swirling is cut out. This is done after this section has been pulled through the eye of the needle.
  • the further embodiment according to claim 3 is expediently provided for pulling out the thread or this section.
  • the cutting itself can again be done by hand or by means of an advantageous embodiment according to claim 4.
  • the correct assignment of a new thread to be fed in can take place through the configuration according to claim 5, from where the feeding and optionally gripping of the threads and the feeding takes place by the advantageous measures according to claims 6 to 10.
  • the two threads are connected in the thread connecting device in a known manner in a device such as is marketed, for example, under the name ClipJet by the company Heberlein Maschinenfabrik AG, CH - 9630 Wattwil, Switzerland (see prospectus of Heberlein Maschinenfabrik AG "ClipJet-FT").
  • a device such as is marketed, for example, under the name ClipJet by the company Heberlein Maschinenfabrik AG, CH - 9630 Wattwil, Switzerland (see prospectus of Heberlein Maschinenfabrik AG "ClipJet-FT").
  • Such known devices are used in texturing and also in spinning technology.
  • the filaments of a thread in the swirl chamber are dissolved and swirled by compressed air. Surprisingly, it has been found that when two threads are introduced together, these two threads are connected to one another by the interlacing of their filaments. It has also surprisingly been found that the strength of the connection is completely sufficient to pull the two different, interconnected threads through the thread tensioner, the
  • the embroidery machine shown in the drawing has a stand 1, an upper arm 2 and a lower arm, usually referred to as base plate 3, in the usual way.
  • the upper arm 2 has an embroidery head 4 in the region of its free end, in which a needle bar 5 is mounted so that it can be driven up and down in the vertical direction.

  • the leading "old” thread 23 is pulled out of the thread pulling device 21 to such an extent that the section 26, via which the threads 23, 24 are connected to one another, is pulled through the needle, to the extent that in the thread pulling direction 25 still a section 27 of approximately 30 to 35 mm remains, which is formed only by the subsequent thread 24.
