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, particularly improved in this regard, and a correspondingly simplified installation method, which ensures reliable positioning of the switching unit and its connection to the drive device in a shorter assembly time than 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 permits the use of ready-to-install, particularly simply constructed and correspondingly inexpensive switching units (“prints”) with integrated operating elements, as a result of which a pre-assembly of the switching units, which was 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 determined in this operating position and in a position with the Drive device connected control system is connected, 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.
  • I contains a machine frame with two side cheeks I 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 I 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 wound in a known manner onto a fabric tree 7 arranged between the side cheeks 1, 2.
  • 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 II, Ila, Ilb which are distributed over the longitudinal extent of the cross member 3 and which are kept at a distance from one another by corresponding plate-shaped spacers 12.
  • the switching units II, 11a, 11b each contain a printed circuit board 13 with integrated switching connections and switches 14, 15, 16, 17, 18 and 19, which act as a break switch can be formed, which are not or only to a very small extent over the projecting surrounding installation area of the relevant circuit board 13.
  • the circuit boards 13 and the spacers 12 are each slidably guided parallel to the longitudinal extension of the cross member 3 with two holding parts formed on their lateral edges in the guide grooves 9 and 10.
  • the installation positions of the switches 14 to 19 are provided with correspondingly arranged operating openings 21 which make the switches 14 to 19 in question accessible.
  • At least one of the switching units II, IIa, Ilb is essentially within easy reach of each section of the weaving width for the operator 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 are required.
  • the switch 14 is used to start the weaving machine
  • the switches 15 and 16 are used to switch on a stepwise rewinding or advancing of the weaving machine
  • the switch 17 is used to synchronize the devices coupled to the weaving machine drive
  • the switches 18 to switch off the weaving machine.
  • the switch 19 can form part of a "two-hand lock" which must be actuated simultaneously with the switch 14 or 15 or 16 in order to release a locking of these switches 14, 15 and 16 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 circuit boards 13 can each be connected via a connecting plug 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, the drive device 27 can be influenced from each of the switching units II, Ila, Ilb.
  • the ribbon cable 23 is guided through an installation space 25 provided between the cross member 3 and the printed circuit boards 13 and the spacers 12 and is connected to the control device 26 in a manner not shown.
  • the switching units II, ILA, ILB and the spacers 12 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 10 and shifted into the intended operating position, where they are determined by the spacers 12 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 II, Ila, Ilb.
  • 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, e.g. a single, centrally arranged switching unit, which can complement about two switching devices arranged on the side walls I and 2.
  • a corresponding plastic profile can also be used for the holding rail.
  • An embodiment is also possible in which the guideways for the switching units II, Ila, IIb are integrated in the crossmember and this is provided with operating openings 21 for the switches 14 to 19 or corresponding switching elements.
  • the guideways for the switching units can also be formed on the outside of the cross member.
