Definitions

  • the invention relates to a gripper for gripping a bobbin or bobbin tube and to a holding element for such a gripper according to the preamble of the independent claims. It also relates to a doffer comprising a doffer bar with at least one gripper according to the invention and to a ring spinning machine with such a doffer.
  • the spinning machines In a large number of spinning machines, particularly ring spinning machines, a large number of already wound bobbins or cops are removed together at the spinning stations of the spinning machine during a bobbin changing process and replaced with empty bobbin tubes.
  • the spinning machines have a doffer device with a doffer bar, which is arranged on the spinning machine so that it can move, for example via a scissor mechanism.
  • a large number of grippers or doffer grippers are in turn arranged on the doffer bar in order to be able to grip the bobbins or the empty bobbin tubes together and to remove or attach them.
  • the individual grippers can preferably be actuated pneumatically and contain a clamping element in the form of a membrane that can be pressurized with compressed air, which is placed over the bobbin or bobbin tube and then grips the bobbin or bobbin tube by introducing compressed air.
  • compressed air supply channels are arranged in the doffer beam, from which the compressed air is fed via feeders to the individual membranes of the grippers.
  • the CN2873813Y describes a gripper of the same design.
  • the gripper has a cylindrical holding element for holding a spool or spool sleeve.
  • a clamping element in the form of a rubber membrane is arranged on the inner wall of the holding element and can be adjusted via a pneumatic device.
  • Membrane makes it possible to grasp the end area of the coil or coil sleeve inserted into the interior of the holding element from the outside.
  • the membrane is fixed to the holding element in the direction of a longitudinal axis via two closure caps, which are arranged on the underside and top of the holding element. The two closure caps are clipped onto the holding element via a snap connection.
  • the gripper includes a fastening element for fastening to a doffer bar.
  • the fastening element is firmly connected to the holding element and contains an air channel for the compressed air supply to the membrane.
  • the fastening element has a hook on its top and an elastic retaining tab on its bottom.
  • the gripper is fixed to a holder via the hook and in a locking groove on the doffer bar via the elastic retaining tab.
  • a gripper with a similar structure is available in the EP0303877A1 shown.
  • the fastening element of the gripper has an elastic retaining tab on its underside and on its top.
  • the gripper can be disengaged and releasably attached to two parallel locking grooves on the doffer beam using the two elastic retaining tabs.
  • the locking grooves make it possible to attach a number of individual grippers along the doffer beam.
  • the membrane When changing a coil or coil sleeve, the membrane is pressurized with compressed air via the air channel. The membrane then contracts in the holding element and grips the coil or coil sleeve at its end from the outside. In order to release the coil or coil sleeve in the holding element again, the membrane is relieved by removing the compressed air. Due to the constantly changing load and relief of the membrane, and the friction of the membrane on the coil or coil sleeve, the membrane wears out after a certain period of operation. The wear is evident in the membrane becoming porous and developing leaks. As a result, a safe replacement of the coil or coil sleeve is no longer guaranteed. It is therefore necessary to replace the worn membrane with a new membrane after a certain period of operation.
  • a major disadvantage of the gripper described is that replacing a worn membrane with a new one is very time-consuming.
  • the gripper To replace a membrane, the gripper must first be removed from the doffer beam by the operator. To do this, the gripper is removed from the CN2873813Y the hook is released from the doffer bar holder and the elastic retaining tab is released from the locking groove or from the gripper EP0303877A1 the two elastic retaining tabs are disengaged from the two parallel locking grooves. Outside the doffer device, the upper and lower closure caps are then released from the holding element. The worn membrane is then separated from the holding element and replaced with a new membrane.
  • the new membrane is then fixed to the holding element in the direction of the longitudinal axis of the holding element using the closure caps and the gripper is attached to the doffer beam. Due to the design of the gripper, replacing a worn membrane is very time-consuming because the entire gripper has to be removed from the doffer beam. Replacing the membrane therefore involves long downtimes for the spinning machine. In addition, the frequent assembly and disassembly of the gripper on the doffer beam leads to unnecessary wear and tear on the gripper's elastic retaining tab. As a result, a sufficient clamping effect of the elastic retaining tab in the locking groove on the doffer beam cannot be guaranteed.
  • WO2016071789 a gripper for gripping a spool or spool sleeve with a fastening element and a cylindrical holding element with a longitudinal axis, wherein the holding element has an inner wall and an outer wall, and a pneumatically actuated clamping element is arranged on the inner wall, which can be pressurized with compressed air via an air channel.
