Definitions

  • the invention relates to an operating method for the change of fabric by means of a transport device in a weaving machine.
  • Transport devices of this type are used so that fully wound goods trees can be brought to further processing quickly and without effort for the weaving staff.
  • JP-A-60 171956 US-A-4606381 describes a transport trolley with gripper arms for taking over the goods tree from a weaving machine. After the full goods tree is positioned in the trolley, a new goods tree is inserted into the weaving machine from the trolley. The new goods tree must then be wound up with an auxiliary device in the weaving machine. To wind up the new merchandise tree, practically only the side of the merchandise tree facing the weaving aisle is accessible. Since the space around the goods tree in the lower area of a weaving machine is usually very cramped, the trolley must be precisely adapted to the weaving machine.
  • the transport device for carrying out the method must be equipped with a receiving device for the full goods tree, at least one warehouse for the new goods tree and a winding tree, and also with scissors for separating the fabric.
  • a device according to the described method can easily be used for different types of weaving machines if there is sufficient space for the gripping arms of the device at the storage locations of the goods tree in the weaving machine. By winding the new goods tree in the transport device, it is practically accessible from all sides, whereby the winding process runs safely and slippage of the wound fabric is avoided.
  • the weaving machines have to be designed in such a way that the warehouse branches can be opened automatically.
  • the structure of the transport device 102 is shown schematically in FIG. 1a. It is divided into driving units 1a and 1b and a support unit 2 arranged between them.
  • the travel units each contain a travel drive.
  • the carrying unit is drawn with a full goods tree 50, an empty goods tree 51, a pinch tree 70 and with gripping arms 40a, 40b. Furthermore, a cutting device 10 is indicated, which is movable in the longitudinal direction of the transport device 102.
  • a cross member 21 connects the right side part 20a to the left side part 20b, the cross member 21 being displaceable relative to the side part 20b. Between the side parts 20a and 20b there are several telescopic rods 225, with which the length of the transport device can be adapted for the type of weaving machine to be operated.
  • the transport device 102 is shown in a view in the longitudinal direction next to a weaving machine 500a.
  • warp threads are fed to a sley 503, where the weft insertion takes place.
  • the fabric 510 is directed to a goods tree 50 via a material train 504 and deflecting rods 505 and wound there.
  • the elements of the weaving machine mentioned are mounted between cheeks 506, which are held together by tubular cross members 507b and angular cross members 508b.
  • the cheeks 506 are supported on foot rails 509.
  • the fabric is wound onto the fabric tree 50 up to a maximum permissible diameter of the cloth wrap. This can be indicated by a sensor within the weaving machine 500a.
  • a logistic control device of the weaving mill then orders the transport device 102 to the relevant weaving machine 500a.
  • Fig. 1 The gripper arm 40a moves according to arrow 40a 'vertically downwards. He swings around one Pivotal point at its upper end to the left and encompasses the bearing journal 55 of the merchandise tree 50 while its legs 42, 43 move into an open position.
  • Fig. 2 The gripper arm 40a has the bearing pin 55 and closed its legs 42 and 43. Parallel to the gripping arm 40a, the gripping arm 40b is moved on the other side of the goods tree. Then the gripper arms 40a, 40b in a vertical movement and simultaneous pivoting movement to the right, the fabric tree 50 from the weaving machine and insert it in the dot-dash position 50 'in the transport device.
  • a manipulator 72 for the winding tree 70 lifts the winding tree 70 in a pivoting movement to the left to such an extent that it can be taken over by the gripping arms 40a, 40b.
  • the gripping arms 40a, 40b move vertically upwards in the transport device 102 and execute a swiveling movement to the right, the loop formation of the fabric 510 starting.
  • fabric must be unwound from the fabric tree 50, which rotates in the direction of the arrow shown.
  • the winding tree 70 also rotates in the direction of the arrow.
  • the weaving machine does not have to be stopped during the change of the fabric tree, so that new weave is continuously removed from the weaving machine 500a in the direction of the arrow 510 ′.
  • Fig. 5 The gripping arms 40a, 40b insert the winding tree 70 into an intermediate storage location and release it.
  • Fig. 6 The winding tree 70 was removed by a manipulator 71 from the intermediate storage location and is pressed against the new goods tree 51. By turning the Anwickelbaums 70 a cloth reserve is formed. The winding tree 70 now begins to bypass the goods tree 51 in the counterclockwise direction, and continues to rotate in the direction of the arrow. The loop of the fabric 510 is further enlarged.
  • Fig. 7 In the dashed position of the winding tree 70 ', the tissue is cut through a cutting device 10 over the entire width. The winding tree is pivoted further according to arrow 71 'into the extended position. The fabric section 510 'hangs freely from the new fabric tree 51. It can be wound by a folding device 11, which is moved in the direction of arrow 11 'against the new goods tree 51, together with the fabric 510 on the new goods tree 51 when it rotates according to arrow 51'. The fabric section towards the weaving machine is tightened at the same time.
  • the gripping arms 40a, 40b have brought the new goods tree 51 from the winding position into an intermediate position in which the goods tree 51 is rotated further by an auxiliary drive 54 until the fabric section 510 is taut.
  • Fig. 9 The gripper arms 40a, 40b insert the new goods tree 51 into the weaving machine 500a, whereupon a drive within the weaving machine brings about the winding of the fabric.
  • the gripping arms 40a, 40b fetch the winding tree 70 from the winding position and insert it into an intermediate position in FIG. 10, from where it is transferred into the original position according to FIG. 1 by the manipulator 72 described in FIG. 3 .
  • FIG. 11 The coupling of the goods tree 51 in the transport device 102 is shown in FIG. 11.
  • One adapter 804 'in the form of a perforated disc with a groove on the outer circumference is screwed onto both sides of the goods tree 51.
  • the gripping arms 40a, 40b grasp the goods tree 51 over the circumference of the adapter disks 804 '.
  • the new goods tree is held and driven in the transport device by means of a claw coupling 804.
  • a drive unit 803 for the goods tree 51 is axially displaced by a carriage 810 connected to the drive unit 803 by means of a device 81, formed from a drive motor 811 and a spindle 812, in relation to the latter Side part 20a of the transport device is moved.
  • a housing 801 of a coupling device 80 for the goods tree 51 sits on a base plate 813 below.
  • the goods tree 51 is rotated by the drive 803, when coupled to the dog clutch 804, the coupling being effected by axially moving the carriage 810.
  • a non-rotatable gear 802 is seated on the housing 801.
  • a housing 710 is mounted freely rotatably on an extension of the housing 801 in front of this gear.
  • a gear 717, which meshes with the gear 802, is in turn freely rotatably mounted in the housing 710.
  • the gear 717 is driven from the other side of the transport device via a shaft 718 by a gear drive 719, the drive wheel 719 'is mounted concentrically with the goods tree 51.
  • the gear 717 rolls on the fixed gear 802, causing the housing 710 to pivot about the axis of the fabric tree 51.
  • a stationary Cam track 714 is attached to the side part 20b. It comes into contact with a roller 713, which is attached to a lever 711, which is mounted on a pin 716 in the housing 710 in a certain angular range of the housing 710 during its rotation.
  • FIG. 13a shows the position of the manipulator 71 in the take-over position for the winding tree 70
  • FIG. 13b shows a position during the bypassing of the new goods tree 51 by the winding tree 70.
  • the drive shaft 718 according to FIG. 12 and the winding tree 70 for example, must be designed as telescopic rods or tubes.
  • the right-hand part of the winding tree 70 in FIG. 12 forms a telescopic tube, while the left-hand part is formed by a telescopic rod and elements 70 ⁇ sitting thereon with the same diameter as the telescopic tube. If the dressing tree 70 is adjusted for a new weaving width, also changes the distance of the segments 70 ⁇ on the winding tree 70 'measured Fig. 12th
