Definitions

  • the invention relates to a device for measuring or adjusting the length of a processing point, for. B. a weaving machine to be fed, thread-like material, with a winding body upstream of the processing point for winding the material.
  • a weaving machine is used as a processing point, and z. B. adopted the weft of the loom.
  • the winding body consists of a conical drum, on the periphery of which a thread guide is arranged which accommodates the turns of the winding body, which are axially offset from one another.
  • the thread guide can be moved in the axial direction, so that the length of each thread turn can also be changed when it is moved to another area of the conical drum. In this way, z. B. in a loom with air jet entry of the weft in the shed adjust the length of the weft to be entered the weaving width.
  • turns have to be axially displaced or moved during operation to change the length of each individual turn. This can lead to tension in the thread, which can promote weft breakage in the weaving machine. Furthermore, a greater or lesser degree of friction can arise on the thread guide in each turn, as a result of which the thread is undesirably stressed.
  • a thread guide must also be arranged axially displaceably on the circumference of the conical drum.
  • the invention has for its object to provide a particularly improved device in this regard.
  • the invention consists in that at least one part of the circumference of the winding body receiving the winding consists of elastic material, so that the diameter of this circumferential part can be changed. Since the diameter of the winding body can be changed in the new device, the length of each thread turn can be changed in a simple manner. The turns therefore do not need to be moved or moved axially. The thread can be particularly protected. An axially displaceable thread guide arranged on the circumference of the winding body is unnecessary. If such a thread guide consisting of several eyelets or a comb is used at all, it can be attached in a stationary manner and serves only to separate the individual turns.
  • a device is known from GB-A-2 027 070, the winding body of which has bars which can be mechanically expanded by a double-threaded spindle.
  • this device is relatively complicated and has the disadvantage that the winding body circumference has slots in which thread flying dust can accumulate and the edges of which may damage the threads.
  • the device according to the invention has the advantage of a uniform, flat peripheral surface.
  • the device according to FIGS. 1, 2 used for an air jet weaving machine, not shown, contains a continuously rotating drive shaft 1 (axis line 24) driven synchronously with the weaving machine, which has a longitudinal toothing 3 in a central section 2 and is shown in FIG 1 continues to the left into a head 5 provided with a support ring 4.
  • a support ring 6 is arranged on the longitudinal toothing 3. Between him and the support ring 4 is made of an elastic material, for. B. rubber, existing peripheral part (jacket, cylinder) 7 clamped.
  • the support ring 6 is supported by a ball bearing 8 against a stationary ring 9 which is held in the axial position by a nut 14 screwed onto a thread 12 of a cylinder 13 surrounding the shaft 1.
  • a ball bearing 15 is arranged between the cylinder 13 and the drive shaft 1.
  • the weft thread 16 runs from a weft thread bobbin 17 located outside the shed of the weaving machine in the direction of arrow 18 into a groove 19 in the peripheral part 7 of the metering drum designated as a whole by 20.
  • z. B. three to four thread turns 27.
  • the weft thread is derived again according to arrow 21 and reaches the further processing points of the weaving machine, for. B. to a weft storage and then to the weft, via which it is entered in the shed of the machine.
  • the nut 14 can be rotated during operation, so that the rings 9, 6 in FIG. 1 after to the left (arrow 71).
  • the result is the upset position 7a of the peripheral part 7 shown in FIG. 2, in which the through knife d of the groove 19 is larger than in FIG. 1.
  • the nut 14 can be used to set any desired thread length to be subtracted from the bobbin 17 during weaving operation, so that optimal weaving operation can be achieved and the smallest possible thread waste on the catching side of the weaving machine.
  • the circumferential part 7 Due to the recess 23 provided on the inner circumference of the circumferential part 7, it can be achieved that the circumferential part 7 contains a section 73 with a smaller cross section 72. As a result, the circumferential part 7 is moved outwards with certainty when the parts 9 move to the left.
  • the thread turns 27a of the weft thread 16a drawn off the bobbin 17a are kept separated by a comb 28 arranged outside the peripheral part 7, so that they cannot run one above the other.
  • the groove 19 can be omitted.
  • the comb 28 can be arranged somewhere opposite the peripheral part 7, e.g. B. as outlined in Fig. 1 or in the middle, d. H. about opposite groove 19.
  • the drive shaft 1 contains a shoulder 31.
  • the other support ring 4a sits on the left.
  • the shaft 1 itself forms the right support ring 6b in FIG. 4 for the elastic peripheral part 7.
  • the shaft continues into a hollow section 36 which surrounds the cavity 35 and which has two bores 37 with an annular space 38 communicates.
  • the annular space 38 is formed between the peripheral part 7 and the hollow section 36 of the shaft 1.
  • the section 36 has threads 39, onto which the support ring 4b is screwed using a threaded ring 41, which lies in a fixed position against the elastic peripheral part 7.
  • the elastic peripheral part 7 is vulcanized onto the support rings 6b and 4b at points 57 and is thus connected to them in a rotationally fixed manner.
  • peripheral part 7 is in the axis-parallel position shown in solid lines in FIG. 4.
  • a screw 42 is screwed into the hollow section 36.
  • the displacement mass 44, z. B. a viscous paraffin or wax, more or less press.
  • the mass 44 is pressed from the inside against the peripheral part 7, so that, for example, the expanded position 7a is created.
  • the turns, not shown, have a greater circumferential length in this position.
  • the drive shaft 1 continues to the left in a cone 48.
  • Shaft 1 has a thread 49 on which an adjusting screw 51 is screwed. This gives the position of a first support ring 6c arranged on the shaft 1 for an elastic peripheral part 7c adapted to the conicity of the cone 48 on the inner circumference.
  • the part 7c is held by a second support ring 4c, which is fixed by a screw 52 screwed into the cone 48.
  • the outer circumference 54 of the circumferential part 7c remains parallel to the axis line 24 when displaced according to arrow 53.
  • the adjustment can only be carried out when the parts are stationary.
  • a tool is placed on the square 61 of the support ring 4d, whereby the ring 4d can be rotated into a changed rotational position relative to the ring 6d after loosening the screw 56.
  • the screw 56 is tightened again, so that the support ring 4d maintains the new position.
  • the diameter of the peripheral part 7d can only be changed when the parts are at a standstill.
  • the peripheral part of the metering drum 20 which receives the thread windings is made of flexible material and suitable means are provided for widening or constricting the peripheral part.
  • the peripheral part 7 does not need to be vol le, axial length to consist of elastic material; for example, only a section of the peripheral part 7 carrying the turns 27 or 27a can be designed to be elastic, while the remaining sections are rigid and consist of metallic material.
