Definitions

  • the invention relates to a weaving machine with a drive device and a cross member running over the weaving width of the weaving machine, on which at least one electrical or electronic switching unit connected to the drive device is arranged, which contains control elements in particular for starting, stopping and controlling the weaving machine.
  • the invention further relates to a method for attaching a switching unit of the type mentioned to the weaving machine.
  • the invention has for its object to provide a weaving machine, in particular in this respect improved and a correspondingly simplified installation method, which ensures a safe positioning of the switching unit and its connection to the drive device in a shorter assembly time compared to previous designs.
  • the cross member is provided with at least one rail-like guide part for the switching unit, and in that the switching unit has at least one holding part which can be moved together with the guide part, and in that the guide part has means for Detection of the switching unit are assigned.
  • the arrangement according to the invention allows the use of ready-to-install, particularly simply constructed and correspondingly inexpensive switching units (“prints”) with integrated operating elements, as a result of which the pre-assembly of the switching units required in previous designs is eliminated.
  • the switching units can rather be attached directly to the guide part, moved in a simple manner into the predetermined operating position and locked. This enables considerable cost and labor savings.
  • the method according to the invention for attaching at least one switching unit to the weaving machine consists in that the switching unit is brought together with the guide part from one end and is moved at least over part of its longitudinal extent into a predetermined operating position and is then fixed in this operating position provides and is connected to a control system connected to the drive device, and that the guide part is attached to a cross member of the loom.
  • a rational, in particular screwless attachment of the switching unit or several switching units can be achieved in a variable operating position.
  • the weaving machine according to FIG. 1 contains a machine frame with two side cheeks 1 and 2 and two cross members 3 and 3a connecting them.
  • a number of heald frames 4 for guiding warp threads 30 and for forming a shed are arranged between the side cheeks 1 and 2.
  • a weft thread is drawn off from a weft spool 5 arranged outside the shed, in a manner not shown, for example by compressed air or a projectile or by gripper, is inserted into the shed and struck in the tip of the shed on the fabric 6 starting there.
  • the fabric 6 is applied in a known manner arranged between the side cheeks 1, 2 arranged tree 7.
  • the cross member 3 extends essentially above the shed over the weaving width of the weaving machine, while the cross member 3 a, as a so-called “chest cross member”, connects the end portions of the side cheeks 1 and 2 on the goods side. 4, the cross member 3 can have a square hollow profile.
  • two mutually opposite guide grooves 9 and 10 are formed in the holding rail 8, which extend substantially over the entire length of the cross member 3.
  • Arranged in the guide grooves 9 and 10 are three plate-shaped switching units 11, 11 a, 11 b distributed over the longitudinal extent of the cross member 3, which are kept at a distance from one another by corresponding plate-shaped spacers 12.
  • the switching units ll, lla, llb each contain a printed circuit board ("print") l3 with integrated switching connections and switches l4, l5, l6, l7, l8 and l9, which act as toggle switches can be formed, which do not or only protrude by a very small amount over the surrounding installation area of the circuit board l3 in question.
  • the circuit boards l3 and the spacers l2 are each ver with two holding parts formed on their lateral edges in the guide grooves 9 and l0 parallel to the longitudinal extent of the cross member 3 slidably guided.
  • operating openings 2l are arranged corresponding to the installation positions of the switches 14 to 19, which make the switches 14 to 19 in question accessible.
  • At least one of the switching units ll, lla, llb is essentially within easy reach of the operator from each section of the weaving width in order to start or stop the weaving machine, so that the removal of fabric defects, in particular warp or weft breaks, correspondingly short downtimes of the weaving machine required.
  • the switch l4 is used to start the loom
  • the switches l5 and l6 are used to switch on a stepwise rewinding or advancing of the loom
  • the switch l7 is used to synchronize the devices coupled to the loom drive and the switches l8 to switch off the weaving machine.
  • the switch l9 can form part of a "two-hand lock", which must be actuated at the same time with the switch l4 or l5 or l6 in order to release a locking of these switches l4, l5 and l6 provided for security reasons. This ensures that when the loom is switched on both hands of the operator remain outside the area of the moving parts of the loom.
  • the printed circuit boards 13 can each be connected via a connector 22 to a ribbon cable 23 which contains a plurality of control lines 24 which are connected to a control device 26 assigned to the drive device 27 of the weaving machine. Via the control lines 24 is the on Drive device 27 can be influenced from each of the switching units ll, lla, llb.
  • the ribbon cable 23 is guided through an installation space 25 provided between the cross member 3 and the printed circuit boards l3 and the spacers l2 and is connected to the control device 26 in a manner not shown.
  • the switching units ll, lla, llb and the spacers l2 can each be inserted at one end of the holding rail 8 removed from the cross member 3 into the two guide grooves 9 and l0 and shifted into the intended operating position, where they are determined by the spacers l2 and without further fastening means can be easily connected to the connector 22.
  • the holding rail 8 can then be fastened to the cross member 3 in the operating position shown.
  • the holding rail 8 remaining on the cross member 3 is equipped with the switching units 11, 11, 11, 11b.
  • a corresponding holding rail 8 can also be attached to the cross member 3a designed as a crossbeam.
  • the holding rail 8 can also contain more or less than three switching units, for example a single switching unit arranged in the center, which can add about two switching devices arranged on the side walls 1 and 2.
  • a corresponding plastic profile can also be used for the holding rail will.
  • An embodiment is also possible in which the guideways for the switching units ll, lla, llb are integrated in the crossmember and this is provided with operating openings 2l for the switches l4 to l9 or corresponding switching elements.
  • the guideways for the switching units can also be formed on the outside of the cross member.
  • corresponding guideways running transversely to the longitudinal extent of the cross member for example vertically, each of which enables the switching units to be inserted from above into the relevant operating position.
