Definitions

  • the invention relates to fabric tree changers for weaving machines, consisting of a transport device with gripping arms and gripping tools, which operate work stations for full and / or empty trees.
  • Weapon changers are used to remove full ware trees from weaving machines, to wind up empty ware trees, to separate from the cloth to the full ware tree, to load weaving machines or empty them with wrapped trees, to transport the full ware trees, to unload the full ware trees in warehouses and to pick them up and the transportation of empty goods trees.
  • Devices of this type are described in U.S. Patent 4,606,381 dated August 19, 1986 and in EP-A-0 296 113 / No. 0296114 / No.0296115 from 12.12.1988.
  • Gripping arms with gripping tools are characteristic of the transport of the sometimes very heavy goods trees from one work station to another. They pick up goods trees and position them both in stations within the transport device and in stations outside the transport device, the range of the gripping arms and the position of the work stations being coordinated with one another.
  • An essential task of the gripping arms is the exact positioning of the gripping tools Recording of the goods trees and the exact positioning of the goods trees in the individual stations. There are therefore only slight deviations in the dimensions of the goods trees themselves and when positioning the transport device in relation to the weaving machine.
  • creep speeds and sensors at the stations are necessary in the final phase to confirm the required end position, or extreme demands on the accuracy of the relative position between the transport device and the work station must be met; both measures that require a complex concept.
  • the invention provides a remedy here. It solves the task of precisely positioning gripping tools and goods trees in certain workstations with simple means.
  • the object is achieved in that elastic transmission elements are installed in the moving transmission elements between the gripping tool and support on the transport device, which deflect when the preset limit forces are exceeded, and in that the gripping arms or the goods trees held by them when starting a device provided by guide rails and Limit stops in their movement are limited.
  • the advantages of the invention can be seen in the fact that the intended end positions are maintained even with larger deviations in the relative position between the transport device and the work station, namely as long as the starting of the work station from the direction and within the flexibility of the transmission elements is programmed and the permissible deformation paths of the elastic ones Transfer elements are not exceeded.
  • the permissible deformation path is exceeded due to an unforeseen obstacle to standstill without damage, while not using the flexibility indicates a likely failure to reach the intended end position, i.e. in the area of the flexibility, the gripper arm can be controlled in an open timing chain and the precisely intended position despite the imprecise relative position between the transport device and the work station to reach.
  • the invention can be used in the same way for devices for changing the weaving harness and / or the warp beam and for devices for changing bobbins or groups of bobbins.
  • a fabric tree changer for weaving machines 2 which consists of a transport device 1 with gripping arms 3 and gripping tools 4, a holding device 5 for full goods trees 17, a holding device 6 for empty goods trees 16, a cloth winding device 7 and a cloth cutting device 8 , as well as a weaving machine 2 with cloth winding station 26 and full merchandise tree 17th
  • elastic transmission elements 11, 12 are installed in the moving transmission elements 3, 9 between the gripping tool 4 and the support 10 on the transport device 1, which deflect when the preset limit forces are exceeded. This deflection is provoked by, on the one hand, the movement of the gripper arm 3 with its roller 25 or a goods tree 16 held by it when approaching a provided cloth winding station 26 on the weaving machine 2 is limited by guide rails 19 and end stops 20, and on the other hand by the cloth winding station 26 predetermined movements are theoretically run over a weaving path s, which is opposite to the flexibility of the elastically deflectable gripper arm 3 and whose amount is greater than the positioning accuracy of the transport device 1 with the gripper arm 3 to the winding station 26 for the cloth 18 in the weaving machine.
  • the vertical transport carriage 9 which carries a gripper arm 3 on a controlled swivel mechanism, moves downwards by a lead screw 21 connected to the transport device 1 via supports 10 and a spindle nut 22 guided in the transport carriage 9 and secured against rotation drives.
  • the gripping arm 3 bends on the one hand by compressing a prestressed spring 11, and on the other hand a prestressed spring 12 between the spindle nut 22 and the transport carriage 9 is loaded more by the buckling forces.
  • the bending movement and the lowering of the transport carriage 9 is limited by the end stop 20.
  • Each further lowering of the spindle nut 22 additionally compresses the spring 12 and increases the distance between the spindle nut 22 and the sensor 24 on the transport carriage 9.
  • the weight compensation 13 with the mass m compensates for part of the dead weight of the transport carriage and gripper arm.
  • Fig. 4 shows two spring plates 28 which are screwed with clamping strips 30 on both sides of the divided gripper arm 3 to form a parallelogram. Shear forces that occur in the longitudinal direction of the goods trees on the gripper arm 3 lead to a parallel displacement against the restoring forces of the spring plates 28, their movement being limited by a tongue 29. If the swivel arm 3 hits an inclined guide rail leading into the correct longitudinal position when lowering and the tongue 29 prevents further evasion, the elastic transmission members 11, 12 deflect and the signals from the sensors 24 or 23 lead to a stop or a reversal of the Movement and further processing of information in the control. The signals from the sensors 24 and 23 are generally checked in the control during the adjustment of the gripper arms 3 to determine whether they may occur in the measured position in the current position and the result of the comparison is processed further as a control signal.
  • the transport device 1 is supported by outer support elements 14, 15 in order to form a sufficiently large stand area for the takeover of the goods trees 17, 16.
