Definitions

  • the invention relates to a device for coupling and uncoupling heald frames according to the preamble of claim 1 and a weaving machine with such a device.
  • the invention has for its object to provide a device for coupling and uncoupling heald frames to or from a shaft drive with several shaft rods, which aligns the coupling parts during coupling and uncoupling and holds positionally stable and which the shaft rods during the movement and leads permanently at standstill.
  • a loom with such a device is characterized according to the invention by the features of claim 4.
  • the shaft rod taking into account the ratio of the free rod length L St to the maximum lifting height, stroke max , according to the invention Free space created below the heald frames to permanently guide the shaft rods in a receiving part. This results in the following advantages that the shaft rods are held in position when the heald frames are missing, are guided during the occasional lubrication stroke and a reduction in the stroke of the shaft drives that are not required is not necessary and that the shaft change is made easier, for example when changing the article, because the shaft rods keep the position unchanged .
  • the shaft drive element and the shed are assigned to one another in the weaving machine in such a way that the ratio of the distance H tot , measured from the pivot point 21 of the shaft rod 2 to the lower edge 22 of the shaft 1 to the max. Stroke height stroke max , measured in the direction of movement of the heald frame max. Is 2.4. It has proven to be an advantage here that the device for coupling and uncoupling heald frames with the receiving part and the actuating member can remain in the same position with respect to the operational as well as the rest position without changing the operating height, ie the level of the specialist tip, among the heald frames. As a result, it is not only possible to maintain the known, advantageous construction dimensions in new weaving machines, but also to retrofit existing weaving machines with appropriate devices for coupling and uncoupling heald frames.
  • Figures 1 and 2 show a preferred embodiment of the device for coupling and uncoupling a heald frame 1 to or from a shaft rod 2.
  • the shaft rod has a rod 3, a coupling 4, which is articulated to a drive member 5 of a shaft drive, not shown and a coupling part 6 which can be brought into and out of engagement with a coupling part 7 on the heald frame 1.
  • the coupling part 6 of the shaft rod 2 has two locking members 8 which can be brought into and out of operative connection with the coupling part 7 on the heald shaft 1.
  • a locking element 8 is provided with a stop rod 9.
  • the device contains two holders 11 which are mounted on a frame (not shown), an axle 12 which is fastened in the holders 11, two support members 13 which are arranged pivotably on the axle 12, an actuating member 14 for the locking members 8 of the coupling parts 6 and a receiving part 15 for the shaft rods 2, the two Support members 13 are attached and an actuator 16 which is operatively connected to the support members 13 to place the actuator and the receiving part from a rest position (Fig. 2) in a working position (Fig. 3).
  • the receiving part 15 has a number of elongated holes 17 which are arranged parallel to one another, the number of elongated holes 17 corresponding to the possible number of heald frames 1 of a shaft package.
  • the actuating member 14 is a continuous part, the length of which is determined by the possible number of heald frames 1 in order to actuate all coupling parts 6 on the shaft drive side at the same time.
  • the receiving part 15 has two projections 18, which are each formed adjacent to the elongated holes 17. The projections 18 protrude from the top and bottom of the receiving part and are provided with V-shaped gates 19 which are aligned with the elongated hole 17 (Fig. 3).
  • the device is arranged below the heald frames 1 in a weaving machine (not shown).
  • the device is mounted in the weaving machine by means of the holders 11 in such a way that the receiving part 15 is arranged at a level such that the receiving part 15 guides the shaft rods 2 during the movement essentially over the free length of the rod 3.
  • the shaft rod 2 is designed such that the ratio of the free rod length L St to max. Stroke height stroke max , measured in the direction of movement of the heald frame 1 is at least 1.1.
  • the shaft drive element 5 and the shed 1 are assigned to one another in the weaving machine in such a way that the ratio of the distance H tot , measured from the articulation point 21 of the shaft rod 2 to the lower edge 22 of the shaft 1, is max. Stroke height stroke max , measured in the direction of movement of the heald frame max. 2.4 is.
  • this assignment creates a free space below the heald frames 1, in which the receiving part 15 is arranged, so that permanent guidance of the shaft rods 2 during the movement is advantageously achieved.
  • This also applies to the non-coupled shaft rods regardless of whether they are actuated by the shaft drive or are stationary.
  • the device is in the working position.
  • the actuating member 14 has pivoted the locking members so that the coupling parts 6, 7 are uncoupled and the receiving part 15 holds the shaft rod 2 in a stable position so that the heald frame 1 can either be lifted off or inserted.
  • the shaft-side coupling part 7 is pushed over the shaft-side coupling part 6, the coupling parts being aligned with one another and connected in a form-fitting manner.
  • the shaft rod 2 is arranged in the V-shaped gates 19 when the device is in the working position. This aligns the shaft rods and keeps them stable. If the device assumes the rest position, the shaft rods 2 are guided in the elongated holes 17, as is shown by the dash-dotted lines in FIG. 3.
  • the device contains an actuator for the shaft lock and a receiving part 15 which guides the shaft rods 2 in the rest position of the device and locks the shaft rods and consequently the shaft locks in the working position in order to insert the heald frames.
  • the device is arranged in a weaving machine below the heald frames 1, so that the receiving part 15 lies at one level and the shaft rods 2 are permanently guided.
  • the space required for this is created by the design of the shaft rod 2, taking into account the ratio of the free rod length L St to the maximum lifting height Hub max .
