Definitions

  • the invention relates to a circular loom for the production of hoses with an annular frame, on the circumference of which vertically movable strands for the warp threads are arranged and in which at least one contactor is rotatably mounted, which carries a weft bobbin.
  • Fire hoses or industrial hoses are generally produced with such circular looms. It is customary to group the strands for the warp threads in compartments, each compartment being mounted on guide rods so that it can move vertically. If, for example, twelve compartments are arranged, a tube with twelve transition corners is created, on which the division shows irregularities.
  • circular looms In addition to circular looms with strands arranged in compartments, circular looms are also known in which a control wheel raises and lowers the warp threads and rotates in front of the contactor. However, weaving errors often occur with this system because the warp threads can slip off. In addition, only a small stroke is possible, so that the rest of the stroke movement must be carried out via a rifle stroke. This creates considerable friction, so that special cooling measures are required at high speeds.
  • the invention has for its object to provide a circular weaving machine of the type outlined at the outset, in which simple retraction takes place with simple measures, so that the division is uniform over the circumference.
  • this object is achieved according to the invention in that the strands are mounted on at least one circular path at a constant distance from one another and individually vertically movable, a circumferential control disk being provided for their height control on the circular path.
  • control disks To produce different bonds, several concentric circular paths of strands with associated control disks can be provided.
  • the number of control discs corresponds to the number of shooters and thus the weft threads.
  • Two or four control disks are provided to produce a linen weave, while a twill weave can be produced with the help of three control disks.
  • the strands are mounted such that they can move vertically in bearing bores, which are incorporated into an upper and a lower ring plate, which are part of the ring-shaped frame.
  • the strands carry cam followers at their lower ends, which run on the control discs.
  • each contactor has a shooter hand which consists of a one-piece round rod and rises counter to the direction of rotation.
  • each contactor carries a flat, approximately triangular weaving knife, which has a part-circular recess on its tip pointing to the axis of rotation of the weaving machine and a nose guiding the weft thread.
  • ring-shaped thread guide rods are attached to the outer circumference of the frame and in the warp thread feed direction in front of the strands, with a tensioning element being provided for each warp thread between two thread guide rods, the lower, freely floating end of which has a switching element that switches off the machine when the thread breaks. which interrupts the electrical power supply, for example.
  • an electronic control unit with a computer to which an input and display unit for the shot density, an input and display unit for the speed of the contactors with an assigned tachometer and a sensor for measurement and display of the length of the hose generated per unit of time are connected.
  • the circular loom shown in Figures 1 to 5 is used to manufacture hoses, such as fire hoses or industrial hoses, and has an annular frame with an upper ring plate 10 and a lower ring plate 12.
  • the two ring plates 10 and 12 connected to each other by a reed or a cage 14 which serves to guide and absorb the horizontal forces of at least one contactor 16 (FIG. 5).
  • the contactor 16 carries a shot coil 18 and is rotated by a rotating thrust washer 20 via a thrust arm 22.
  • the horizontal forces are absorbed by the cage 14 via toothed support rollers 24, while the vertical forces are transmitted from support rollers 26 to an upper guide track 28 and a lower guide track 30.
  • the upper guide track 28 is attached to the upper ring plate 10, while the lower guide track 30 is attached to the lower ring plate 12.
  • Rod-shaped strands 32 are used to raise and lower the warp threads.
  • the strands 32 are arranged at a constant distance from one another on an associated circular path 38 (or 38 ', 38''), the circular paths, as shown in FIG. 4, being concentric to one another.
  • Bearing holes 40 serve for the vertically movable mounting of the strands 32 are incorporated into the upper ring plate 10 and into the lower ring plate 12 corresponding to the circular paths 38 and 38 ', 38'', respectively.
  • the strands 32 carry cam follower rollers 42 at their lower ends.
  • the cam follower rollers 42 of all strands 32 of a circular path 38 or 38 ′, 38 ′′ run on an associated, rotating control disk 44, which thereby raises or strands the strands 32 in the required manner. lowers.
  • FIG. 3 shows, a total of three control disks 44 are provided corresponding to the three circular paths 38, 38 'and 38' 'in order to control the three stranded rims during their vertical movement.
  • each contactor 16 is also provided, each of which carries a shot coil 18, the rotational movement of which is decelerated by a shot coil brake 46.
  • Each contactor 16 has a shooter hand 48 which consists of a one-piece round rod which rises in front of the weft bobbin 18 in the opposite direction to the direction of rotation according to arrow 50 in FIG. 5 (arrow 52), so that the associated weft thread 54 is raised in this way.
  • a nose 56 with a radial guide groove 58 which is attached to the front edge of a weaving knife 60, which is part of the contactor 16.
  • the front edges of the three triangular weaving knives 16 are formed as part-circular recesses, whereby a circular opening 62 is formed through which the hose is pulled down during its manufacture.
  • FIG. 3 shows that an outwardly projecting support member 64 is attached to the upper ring plate 10 and the lower ring plate 12, to which annular thread guide rods 66 are attached.
  • the warp threads 36 are guided over these thread guide rods 66, which are arranged concentrically to one another, a brake actuator 68 being provided radially outside the thread guide rods 66 for each warp thread 36.
  • a tensioning element 70 is provided for each warp thread 36, the upper end of which is suspended in the warp thread 36, while the lower, freely floating end carries a switching element 72 which closes a contact 74 when the thread breaks and thereby switches off the machine.
  • Figure 6 shows an electronic control unit for the circular loom according to the invention.
  • Three display units 78, 80 and 82 are connected to a computer 76, of which the display unit 78 shows the weft density, the display unit 80 the speed and the display unit 82 the machine output in m / sec.
  • the speed of the contactors is measured by a sensor 84, while the performance of the machine, i.e. the take-off speed of the hose produced, a sensor 86 measures.
  • the shot density display unit 78 is connected to an input unit 88 and the speed display unit 80 is connected to a corresponding input unit 90.
  • the corresponding number is entered on the input unit 88, while the maximum speed of the contactors can be determined on the input unit 90.
  • the power is measured continuously via the sensor 86, the speed being controlled in accordance with the desired weft density.
