Definitions

  • the invention relates to a terry weaving machine based on a oscillating displacement of the stop edge of a fabric to be manufactured works in rhythm and in sync with the drive of a reed.
  • the pile formation can take place by means of the so-called weaving shop control according to the invention according to EP 0 298 454 B1.
  • the weaving shaft is connected to a servo drive which is independent of the weaving machine drive and which can be controlled freely and in individual wefts.
  • terry weaving machine For the production of terry goods with variable pile height by means of the so-called fabric control, the applicant has produced a terry weaving machine as a prototype, which has a separate drive that is independent of the loom drive for free and single-weft control, which is connected to transmission elements for changing the pile height during the weaving process. These transmission elements, which act on the pile organs, control the movement of the fabric and that of the basic chain.
  • a hydraulic linear amplifier with integral proportional control was used as a separately controllable drive.
  • the pile height was able to meet requirements specified and smooth weaving for borders can also be realized.
  • EP 0 350 446 B1 a terry weaving method and a weaving machine with pile forming elements are known, the weaving machine having measures to implement terry fabrics with a variable pile height according to the principle of the shop control. Furthermore, EP 0 350 446 B1 discloses a weaving machine which realizes terry fabrics with a variable pile height according to the principle of fabric control. To change the pile height, at least one pile forming element is actuated by a separate drive, which can be controlled individually and individually. A servo motor is proposed as a separate drive, which is coupled to at least one pile forming element via a reduction gear and / or transmission elements.
  • a terry weaving machine with a terry device for continuously changing the pile height during weaving is known.
  • the terry formation also takes place on the basis of the so-called fabric control, ie the weft stop edge of the fabric experiences a shift towards and away from the reed position of the reed in rhythm and synchronously with the weft stop movement of the reed.
  • the terry formation device consists of a ball screw mechanism, which is connected to a pattern-controllable motor drive to reverse the direction of rotation of the ball screw.
  • a rotatably mounted angle lever is articulated to the mechanism with one of its lever arms.
  • the other lever arm is connected via a coupling to a so-called rotatably mounted intermediate lever which, in addition to a lever for articulating the coupling originating from the angle lever, has two further lever arms.
  • a second coupling is articulated on one of the further lever arms, which is connected to a component causing the tissue displacement, while a third coupling is articulated on the other further lever arm, which acts on a component influencing the polette tension.
  • a variable pile height is based on a servo motor which is controlled independently of the loom main drive and which is connected to organs for tissue displacement or with organs for adjusting the stop position of the reed.
  • a servomotor requires a high drive power to carry out the terry movement.
  • EP 0 518 809 A1 discloses a weaving machine according to the preamble of claim 1 with a pile height adjustment device, the drive of which is an eccentric drive derived from the main weaving machine drive.
  • the pile height adjustment device is placed between the eccentric drive and the breast tree of the weaving machine.
  • the features of the pile height adjustment device consist essentially of at least one lever acting on the breast beam and of the eccentric drive acting on coupling elements on the lever, and of means which influence the effective length of the lever arm indirectly connected to the eccentric drive.
  • the object of the invention is therefore to provide a pile height adjustment device for Terrycloth looms of the type mentioned in the preamble of the main claim to create whose terry formation is based on the fabric control and the pile height, starting from a specified first pile height, is continuously changeable.
  • a web height adjustment device consisting of a gear transmission unit with a separately controllable electromotive drive is integrated in a weaving machine equipped with a basic pile forming device, which works on the basis of the so-called fabric control, in a mechanism that transmits the terry toweling movement.
  • the pile height adjustment device takes, based on known precautions to carry out a so-called basic terry movement, such influence these precautions that within a given framework change the Pile height, starting from the base pile height, can be effected.
  • the weaving machine 1 shown in FIG. 1 has a basic warp beam 2 with a basic warp 3, which, starting from the basic warp beam 2, is led via a tensioning beam 4 to the shedding elements 6 forming the shed 5 and finally to the binding point 7 of the fabric 8.
  • the finished fabric 8 is guided over a fabric shifting component, which in the present case is the feed roller 9.
  • the fabric 8 passes from the single roller 9, possibly via further deflection rollers, which are not shown here, to the goods tree 10.
  • the pile chain 11 is guided from a pile warp beam 12 after a deflection roller 13 to a dancer shaft 14 and from there through the shedding elements 6 to the binding point 7 of the fabric 8.
  • the drive for at least one so-called terry toweling cam 16 and the drive for a reed 18 connected to the sley 17 are derived from a schematically illustrated main loom 15 drive.
  • a tension spring 22 acts on the double lever 20, which ensures that the scanning roller 21 of the double lever 20 does not lift off the eccentric disk.
  • a pile height adjustment device 23 is arranged between the double lever 20 and the drawing-in roller 9 and has a motor drive 24 which is independent of the main drive 15.
  • At least one coupling 25, 25a must be provided between the double lever 20 and the drawing-in roller 9.
  • the pile height adjustment device 23 functions as a link for transmitting a basic terry movement from the terry cam 16 with a double lever 20 to the drawing-in roller 9.
  • One end of the respective coupling 25, 25a is articulated in the pile height adjustment device in mutually different arrangement planes.
  • the other end of the one coupling 25 is fastened to the double lever 20 in an articulation point which determines the basic terry movement.
  • This articulation point can lie, for example, in a longitudinal guide 20a of the double lever 20.
  • a wide variety of basic terry movements can be defined in a known manner.
  • the other end of the other coupling 25a is articulated on a lever arm 26 which is firmly connected to the drawing-in roller 9.
  • FIG. 2 shows the pile height adjustment device 23 designed according to the invention, which consists of a gear unit and a drive 24 connected to the gear unit.
  • the transmission unit in turn is formed from a combination of a first partial transmission 27a with a second partial transmission 27b.
  • the first sub-transmission 27a consists of a drive pinion 28 connected to the armature shaft 24a of an electromotive drive 24 and of a gear 29 which is arranged on a common transmission shaft 30 in a rotationally fixed manner and which meshes with the pinion 28.
  • the second partial transmission 27b consists of a drive pinion 31 which is connected to the common transmission shaft 30 in a rotationally fixed manner and of a toothed sector piece 32 which is in engagement with the drive pinion 31 and which is connected to at least one lever-like bearing plate 33 via a first connecting bolt 34.
  • a drive pinion 31 which is connected to the common transmission shaft 30 in a rotationally fixed manner
  • a toothed sector piece 32 which is in engagement with the drive pinion 31 and which is connected to at least one lever-like bearing plate 33 via a first connecting bolt 34.
  • two identically designed bearing plates 33 are provided, which are rotatably mounted and spaced apart from one another about the central axis 30a of the transmission shaft 30.
  • the tooth sector piece 32 is in this case integrated between the two bearing plates 33.
  • a second connecting pin 35 is provided spaced apart from the first connecting pin 34 on the tooth sector piece 32.
  • One of the couplers 25, 25a is articulated on each of the connecting bolts 34, 35.
  • the drive 24 is connected via a control line 36 to an electronic control 37 which controls the drive 24 on the basis of a pile height selectable via the display 38.
  • an electric motor drive for example, a pneumatic or hydraulic drive can be provided.
