The invention "relates to a Traneporteinrichtung a automatic shell changing device aura replacement of On the spindles of a textile machine, preferably a spinning or twisting machine, full sleeves are placed against empty ones Pods.

In a fee-known HüXsenwecBscleinrlchtung of this type, the transport device has a conveyor belt having a first transport unit for the longitudinal direction of the machine for the transport of the empty and empty tubes, wherein the tubes can be attached to tube holders that are arranged on the conveyor belt. The conveyor belt is arranged in such a way that the plane of the sleeve holder torn open by its sleeve holder falls approximately into the spin hole torn open by the spindles. Furthermore, a second transport unit is provided for transporting the full sleeves from the spindles to the conveyor belt and the empty sleeves from the conveyor belt to the spindles, the second transport unit having a gripper bench on which a corresponding number of spindles Number of gripping members for gripping the full and empty sleeves is arranged. This second transport unit has a plurality of guide rods arranged at a distance from one another along the machine, on each of which a slide that can be driven by a drive device is guided, with these slides jointly carrying the gripper tape.

These guide rods are mounted on a common shaft and together around a pivot axis parallel to the spindle plane pivotable. By moving the slide up and down on the guide rods and appropriate pivoting of the guide rods the gripping organs can be brought into single grip with the full sleeves and the full sleeves placed on the conveyor belt will. The empty sleeves placed on the conveyor belt can then be moved into the gripping path of the gripping organs and by appropriately pivoting the guide rod and moving the carriages on the guide rods on the spindles transported and attached there. This transport facility is relatively simple and reliable, but it has, among other things. the disadvantage dad the pivoting movement of the Guide rods and the upward and downward movement of the carriage guided straight on the guide rods are separate drives and controls require. Also located at some spinning or twisting machines vertically below the spindles drive elements of the machine in question, for example Curves to control the lifting movement of the ring rail. With these machines the installation of the first Traaeportaggregates prepares Difficulties, especially when the transport device is subsequently built into the Maaohlne in question shall be.

The invention is in particular the task of create a transport device of the type mentioned at the beginning, which is simple and reliable, and in which the

Disadvantages of the known transport devices are avoided. Another object of the invention is to provide a transport device sstt that can also be retrofitted to textile machines, in particular spinning or twisting machines can be incorporated without significant modifications to the machine concerned being necessary. The invention also aims at a transport device to create through which the operation of the Spinnoder Twisting machine is not obstructed during spinning or twisting.

To solve this problem is a transport facility an automatic sleeve changing device büb replacement from Tollen sleeves attached to the spindles of a textile machine, preferably a spinning or twisting machine against empty tubes, with a first transport unit having a conveyor belt for the longitudinal direction of the machine the delivery and removal of the empty and rolled tubes, where the. Sleeves can be attached to the sleeve holder on are arranged on the conveyor belt, furthermore with a «wide. Transport unit for transporting the full tubes from the spindles to the conveyor belt and the empty tubes from the conveyor belt to the spindles, the second transport unit has a gripper bench on which at least one gripping element is arranged for gripping the full and empty tubes, is, and with an automatically controlled drive device for driving and controlling the movement of the first and second Traneportaggregates

The wide slide of each transport unit 29 is coupled to a traction means designed as a roller chain 35 by means of a bearing journal 56 attached to the roller chain, which engages in a cylindrical bearing bore 37 (Fig. 3) of a holding arm 38 arranged on the disputed sole. This endless roller chain 33 is placed over a drive sprocket 39ι a guide roller 40 and a guide roller 41. It has "white main tracks 43" 47 parallel to the spindle plane 70. The drive chain wheel 39 is fastened in a rotationally fixed manner on a drive shaft 42 extending along the machine. The drive shaft is driven by a directionally reversible drive motor 43, the drive function of which can be controlled by means of a control device indicated at 44.
