Definitions

  • the invention relates to a device for releasably attaching a thread head a twisting machine according to the preamble of claim 1.
  • Thread heads of this type are used in the production of technical threads (cords) for bringing together the threads coming from the two supply spools used. They are also known as cord regulators.
  • twisting heads or cord regulators are one on the support plate Twisting machine attached with the help of screws, usually with three in evenly spaced Allen screws.
  • the thread head consists of a housing that rotates with the support plate of a twisting machine is releasably connectable and a downward-pointing rotor is free within this housing is rotatably mounted.
  • This rotor carries a number of guide rollers over which the to twisting threads run and has a thread at which the two to twisting threads twisted together, d. H. be twisted. Then runs the twisted thread through central openings within the housing of the Twisting head and the support plate of the twisting machine as well as further deflection, Tensioning and control devices up to a take-up reel.
  • the cord regulator or However the thread head can be removed regularly. This assumes that everyone Fastening screws are loosened. For subsequent attachment of the thread head the screws must be kept and the fastening done, as well as that Solve with the help of tools. This procedure is time consuming and requires the right one Tool, does not involve the risk of losing screws and furthermore the risk Fully tightened screws resulting in twisting machine failure during operation if the twisting head is loosened due to loosening of a screw detaches from the support plate of the twisting machine.
  • FIG. 1 shows the twisting head 1 fastened to the support plate 2 of a twisting machine.
  • the twisting head 1 has a substantially cylindrical housing 5, on the latter Underside is a rotor 15 which rotates freely within the housing 5 is stored.
  • the rotor 15 is inclined from below by a thread balloon coming thread 16 through an opening 17 within a plate 18 of the rotor 15 runs, with respect to the housing 5 in rotation about the central axis A.
  • the rotor 15 has a number of deflection rollers 19 which are not of interest here whose primary job is to tighten the thread tension between the two to keep twisting threads constant.
  • the rotor has above the deflection rollers 19 15 the so-called thread point 20, i.e.
  • a locking ring 3 On the support plate 2, which can be seen particularly well in FIG. 3, there is a locking ring 3 a plurality of locking lugs 4 rigidly attached, for example screwed or pressed in.
  • the locking ring 3 has nine in the same embodiment Angular distance of 40 ° to each other locking lugs 4 on the inside are oriented and, viewed from the radial direction, initially rectangular cross section and a trapezoidal or roof-shaped tapering on the top Have cross-section.
  • the locking lugs 4 are arranged obliquely inwards.
  • the locking ring 3 has intermediate spaces between the respectively adjacent locking lugs 4 on.
  • a locking element ring 6 On the side of the housing 5 of the twisting head 1 there is a locking element ring 6 also nine arranged on its outside and radially outwards protruding locking elements 7, which are also at the same angular distance from each other are arranged.
  • the locking elements 7 have, viewed from the radial direction, on their The top has a trapezoidal or roof shape that tapers upwards.
  • the underside of the locking elements 7 has a recess 9 in the middle bevels running upwards on both sides of the recess 9
  • Bottom 8 of each locking element thus has a wavy appearance from the side seen starting with a bevel 12 running from top to bottom, the first upward and then downward recess 9 and then again bevel 12.
  • the outer diameter of the nine locking elements 7 on the locking element ring 6 is larger than the inner diameter of the plurality of locking lugs 4 on the locking ring 3. Furthermore the distance between two adjacent locking lugs 4 is greater than the maximum width of one Locking element 7.
  • the housing 5 of the twisting head 1 has below in the illustrated embodiment the locking element ring 6 an axially slightly displaceable, with a spring washer 13th biased disc 14 in the direction of the locking element ring 6.
  • the disc 14 can upwards, i.e. towards the locking elements 7, do not dodge further, but against the Pressure of the spring washer 13 down, that is, in the direction of the twisting head 1, pressed become.
  • the twisting head 1 is fastened to the support plate 2 of the twisting machine by Grasping the housing 5 of the twisting head 1 provided with handle bars and attaching to the support plate 2, as shown in Figure 3, and by moving the Housing 5 in the direction of the support plate 2, the upper bevels 20 of the Locking elements 7 and then the entire locking elements 7 between adjacent Slide locking lugs 4 of locking ring 3 through.
  • the housing 5 through Sliding along the locking lugs 4 on these bevels 20 of the locking elements 7 easily twist. Only in the rare case that exactly the not beveled Tops of each locking element 7 to lie on the undersides of each locking lug 4 no insertion can take place. In this case, the housing 5 only has to manually rotated slightly, whereupon the locking lugs 4 on the Bevels 20 of the locking elements 7 come.
  • the twisting head 1 is released from the support plate 2 of the twisting machine in Conversely, that is, by slightly rotating the housing 5 while simultaneously Apply pressure upwards and remove the twisting head 1.
  • the described device enables a very quick release and insertion of the Twisting head 1 in a twisting machine. It also avoids any risk of a wrong one Attachment, because if the locking lugs 4 are not fully locked into the Recesses 9 of the locking elements 7 of the twisting head 1 immediately out of the support plate 2 falls out. In this case, the locking lugs 4 are not in the recesses 9, but on the side bevels 12 on the underside 8 of the locking elements 7 and the locking elements 7 slide down under the pressure of the spring washer 13 - The twisting head 1 falls out into the hand of the fitter.
  • the twisting head Only when complete locking by engaging the detents 4 in the Recesses 9 is reached, the twisting head is in a safe operating position and can then no longer fall out.
