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 SchuQ bobbin.
  • fire hoses or industrial hoses are generally manufactured. It is customary to group the strands for the warp threads in compartments, each compartment being vertically movable on guide rods. If on the scope e.g. twelve compartments are arranged, a tube with twelve transition corners is formed, on which the division has 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.
  • weaving errors often occur in this system because the warp threads can slip off.
  • only a small stroke is possible, so that the rest of the stroke movement must be carried out over a rifle stroke. This creates considerable friction, so that special cooling measures are necessary at high speeds.
  • the invention has for its object to provide a circular weaving machine of the type outlined at the outset, in which, with simple measures, a uniform feed takes place, 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 is.
  • a plurality of concentric circular paths of strands with associated control disks can be provided.
  • the number of control discs corresponds to the number of contactors 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.
  • each contactor has a shooter hand consisting of a one-piece round rod and rising in the opposite direction 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 is the machine when the thread breaks has switching switching element that 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 assigned tachometer and a sensor for measuring and displaying the length of the hose produced per unit of time are connected.
  • FIG. 1 shows a schematic side view of a part of the circular loom according to the invention to show the heald arrangement and the associated control disk
  • FIG. 2 shows a vertical section through part of the circular loom with a heald ring
  • FIG. 4 the top view of a part of the upper ring plate
  • FIG. 5 the enlarged top view of a contactor
  • FIG. 6 the schematic block diagram of the control unit for the circular loom according to the invention.
  • the circular loom according to the invention shown in FIGS. 1 to 5 is used to manufacture hoses, for example fire-fighting hoses or industrial hoses, and has an annular frame with an upper ring plate 10 and a lower ring plate 12.
  • the two rings are ⁇ plates 10 and 12 by a reed ode: -: a cage 14 connected to each other, 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 set in rotation 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 fastened to the upper ring plate 10, while the lower guide track 30 is attached to the lower ring plate 12.
  • Rod-shaped strands 32 each with an elongated hole 3 ⁇ 1, through which the associated warp thread 36 is guided, serve 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 criss-cross paths, as shown in FIG. 4, running concentrically to one another.
  • Bearing holes 40 are used for vertically supporting the strands 32. speaking the circular paths 38 and 38 ', 38''are machined into the upper ring plate 10 and into the lower ring plate 12.
  • 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 the strands 32 in the manner required or lowered.
  • FIG. 3 shows, a total of three control disks 44 are provided in accordance with the three circular paths 38, 38 'and 38' 'in order to control the three stranded rings in their vertical movement.
  • each contactor 16 is also provided, each of which carries a shot coil 18, the rotational movement of which is delayed 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.
  • a nose 56 ' For guiding the weft thread 54 there is a nose 56 ' with a guide groove 58 running in the radial direction, which is attached to the front edge of a W ⁇ b ⁇ ss ⁇ rs 60, the part of the contactor 16.
  • FIG. 5 it is indicated that the front edges of the overall triangular weaving knives 16 are designed as partially circular recesses, as a result of which a circular opening 62 is formed, through which the hose is pulled downwards 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, on which ring-shaped thread guide rods 66 are attached.
  • the warp threads 36 are guided over these thread guide rods 6 ′ 6 arranged concentrically to one another, with a brake actuator 68 being provided 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.
  • FIG. 6 shows an electronic control unit for the circular weaving machine according to the invention.
  • a computer 76 Connected to a computer 76 are three display units 78, 80 and 82, of which the display unit 78 shows the shot density, the display unit 80 shows the speed and the display unit 82 shows the machine output in m / sec.
  • the speed of the contactors is measured by a sensor 84, while the power of the machine, i.e. the withdrawal speed of the manufactured hose, a sensor 86 measures.
  • Di ⁇ • display unit 78 for the weft density is impressed with a standardized 88 Einga ⁇ connected, and di ⁇ Anz ⁇ ige ⁇ inh ⁇ it 80 for di ⁇ Dreh ⁇ number is connected to a corresponding input unit 90th
  • 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 continuously measured by the sensor 86, the speed being controlled according to the desired weft density.
