Definitions

  • Tensioning unit for the weaving chain of a weaving machine having a first outer and second outer side cheek, with functional elements on the warp beam side that extend across the weaving width, such as a coating roller, a deflecting roller, and with at least one element that applies a tension force and with elements that apply the tension force transfer the match tree.
  • a device for tensioning a warp on a weaving machine is known from European patent 0 109 472 B1.
  • the object on which the known invention is based is, inter alia, to meet the requirements for weaving at high warp tensions, for constant warp tension during weaving of the warp beam and for the lowest possible inertia of the tensioning element which tension the warp during its periodic oscillating movements.
  • a device which consists of a spring-like rod-like tensioning element and a support tree on which the tensioning element is supported several times over the weaving width, and about the center axis of which the tensioning element is arranged pivotably.
  • the tensioning element should be a tensioning element which is rigidly connected to the supporting tree and is not resilient in itself.
  • the known solution meets the aforementioned requirements in that the supporting beam is supported together with a deflecting beam for the warp threads between the warp beam and the tensioning element in several bearing plates connected below the weaving plane with a machine-fixed support.
  • Such a support enables the tensioning element as well as the supporting tree and the deflecting tree to be designed with relatively small cross-sectional dimensions and consequently with little mass.
  • a disadvantage of this solution is that the tensioning element is inevitably in fixed connection with the supporting tree via corresponding connecting pieces. Such a design is costly with regard to the manufacturing process of the support tree tensioning element connection.
  • a device for tensioning the warp is also known from European patent application 0 409 306 A1.
  • the object of the solution according to the invention here is to provide a device for tensioning the warp which is suitable for periodically influencing the tension of the warp as a function of the warp tension present during the change of shed and the rip fence.
  • the object is achieved in that the back rest is received between two supports arranged within the weaving machine and each support is mounted on a support arm running below and parallel to the weaving plane, which in turn has one free end on a second but pivotally mounted one Arm is articulated.
  • the other free end of the support arm is operatively connected to an eccentric shaft of a gear means.
  • the warp should be periodically tensioned and relieved by means of an eccentric stroke applied periodically by the gear means.
  • the aforementioned technical solution is not based on the design of a particularly low-mass tensioning unit for warp tensioning, including the coating roller and the deflection roller.
  • the object of the present invention is to provide a tensioning unit for the warp, which dispenses with a conventional supporting tree on which the coating roller is supported, in which the coating roller and the deflection roller are designed to be low-mass and loosely received, and the tensioning unit as such is within the Weaving machine is pivotable and adjustable back and forth in the weaving direction.
  • the roller lever is operatively connected to a lever element, via which the warp tension is transmitted from at least one tensioning element to the coating roller.
  • a lever element is a cam, for example.
  • Each cam disk is supported by a shaft which rotates through the end shields and which cooperates with the tensioning element via at least one lever which is connected to this shaft in a rotationally fixed manner.
  • the roller lever is designed as a one-armed lever in the case of interaction with the cam disc. A Two-armed lever formation is conceivable, for example, if the aforementioned shaft with the cam disks is dispensed with.
  • the clamping unit 1 acc. 1 to 3 forms, inter alia, a rotationally symmetrical cross member 2 which is carried in the receptacle 3 of the component 4 and is adjustable about its longitudinal axis 2A.
  • the cross member 2 can be locked in the receptacle 3 by means of the screws 5.
  • the component 4 is shown in FIG. 2 as an individual part.
  • the component 4 is over with the component 7 arranged in a height-adjustable manner on the first outer side cheek 6, see FIG. 2 the guide 7A and the elongated holes 7B are connected by means not shown which pass through the elongated holes 4A and 4B in the component 4.
  • each component 4 is also a in the weaving direction according to the bolts 8.
  • Carrier 10 pointing arrow 9 is present, to which a first articulation point 11 of a tensioning element 12, for example a tension spring, is articulated.
  • the second articulation point 13 of the tensioning element 12 is connected to the free end of a one-armed lever 14. It should be mentioned that the components 4, 5, 7 are once again present in identical configuration and arrangement on the opposite weaving machine side.
  • a plurality of end shields 15, but at least a first outer and a second outer end shield 15, are arranged on the cross member 2 extending from one weaving machine side to the other. All end shields 15 lie in a common plane.
  • the individual end shields 15 form a bearing 15A at their free end, preferably a two-point roller bearing for receiving the deflection roller 16, see also FIG. 3.
  • the two bearing rollers 17 are rotatably mounted on the axes of rotation 18 integrated in the bearing plate 15.
  • a roller lever 19 designed as a single-armed lever, best seen in FIG. 1 and FIG. 3, is pivotably mounted about an axis 20, preferably close to the bearing plate 15.
  • the axis 20 is fixed on the bearing plate 15 so that the roller lever 19 together with the coating roller 21 can perform an adjustment and a periodic pivoting movement in the directions of the double arrow 22 according to the requirements.
  • the roller lever 19 here also has a two-point roller bearing 19A for the coating roller 21, see also FIGS. 1 to 3.
  • the axes of rotation 23 of the two bearing rollers 24 are integrated in the roller lever 19.
  • a scanning roller 25 is integrated in the roller lever 19 such that its axis of rotation 26 lies at the intersection of the obtuse angle of a triangle which can be formed between the axes of rotation 23 of the bearing rollers 24 and the axis of rotation 26 of the scanning roller 25.
  • Cam discs 29 are connected to a shaft 28 which passes through the end shields 15 in the bearing 27 and on which at least one spring-loaded lever 14 engages in a rotationally fixed manner.
  • One cam 29 each is in operative connection with the relevant scanning roller 25 of the roller lever 19, see also FIGS. 1 to 3.
