Definitions

  • the invention relates to a central magazine for a Tube feed device producing a package Textile machine according to the preamble of claim 1.
  • a sleeve magazine with a sleeve transfer device is assigned to each of the two package changers in the area of the machine ends of the false twist machine.
  • the sleeve magazines each have a plurality of shafts, in which empty sleeves are arranged in the manner in which they are required by the sleeve stores of the package changer.
  • a sleeve transfer device in the form of a conveyor belt is mounted below the empty tube receiving shafts.
  • the conveyor belt is guided around a drive roller and a deflection roller; its conveying direction is transverse to the machine longitudinal direction.
  • the conveyor belts of the tube magazines convey the empty bobbin tubes directly into the tube storage of the cross-wound bobbin changer in question via a discharge opening without changing their orientation.
  • a large number of conical empty sleeves are stored in a vertical orientation.
  • the conical sleeves are stacked in such a way that the bottom sleeve can be pulled off by a special device and transferred to a sleeve transfer device via a slide.
  • the sleeve transfer device is designed as an elevator, which transfers the sleeves to a machine-long sleeve conveyor belt.
  • the sleeves then reach the area of a movable operating unit that supplies the winding stations of the textile machine via the sleeve conveyor belt.
  • the control unit preferably a cross-wound bobbin changer, has, inter alia, a sleeve buffer, a sleeve receiving device and a sleeve transfer device.
  • EP 0 262 726 A2 describes a cross-wound package Textile machine with at least one machine end arranged central magazine.
  • the central magazine shows revolving storage chains with mandrels for empty tubes on.
  • One integrated in the central magazines Sleeve transfer device pushes the if necessary requested sleeves from the mandrels, so that these over a slide on a machine-long sleeve conveyor belt get the sleeves arranged to a movable Cross coil changer promotes.
  • the package changer takes that requested sleeve from the conveyor belt and changes it directly in the bobbin frame of the winding unit concerned on.
  • US Pat. No. 5,350,128 discloses a device for loading bobbin tubes from an empty tube storage onto the transport mandrel of an operating carriage.
  • the device is designed both for the transport of bobbin tubes and for the transport of heavy cross-wound bobbins wound with synthetic yarn and has a device for receiving and transferring bobbin tubes which can be moved in the vertical direction.
  • the device has a rotatably mounted rake with projecting tines, the division of which is matched to the diameter of the winding tubes.
  • a layer of winding tubes is taken from an empty tube memory and initially positioned on a so-called grid base.
  • the bobbin tubes are then brought into an extended position by means of a transverse displacement device and then transferred to the transport mandrel of the operating carriage by a replenishment device.
  • the bobbin tubes relocated several times until it finally hit the mandrel of the control cart are transferred.
  • the structure of the doffing device known from JP 60-244 767 A is also quite complicated.
  • This doffing device also has, inter alia, a rotatably mounted sleeve gripper which can remove a bobbin tube from a transport carriage and insert it into the bobbin frame of a textile machine.

  • the gripper carrier has a plurality of sleeve grippers which are arranged next to one another and can be controlled in a defined manner.
  • the number of sleeve grippers corresponds to the number of storage columns in the storage unit. To take over a sleeve stored in the loading chutes of the storage columns, only a vertical positioning of the gripper carrier and a control of the relevant sleeve gripper are necessary. Subsequently, the received sleeve can be brought into a position in a simple manner by moving the gripper carrier into an overhead transfer position, in which position it can be easily taken over by a gripping device arranged on the sleeve transport carriage of the sleeve transport device.
  • the central magazine has a storage unit, which, preferably easily replaceable, is fixed to a central unit.
  • a storage unit which, preferably easily replaceable, is fixed to a central unit.
  • the storage unit can first be completely emptied and then quickly and easily replaced with a new, filled storage unit.
  • the new storage unit was fitted with new empty tubes in a tube loading station, which can also be located in a remote department. This means that the ability to quickly and easily replace an empty storage unit with a full storage unit eliminates the need for operating personnel to monitor the filling level of the storage unit at short intervals and to constantly refill new empty tubes.
  • each storage column is a separate one Assigned sleeve gripper.
  • the most vertically movable Gripper carriers arranged sleeve grippers are indeed shifted together in terms of their working height, the Sleeve grippers are via the central magazine's own Control device, however, defines, that is, individually controllable.

This means that the sleeve grippers are optimally adapted to the known difficult environmental conditions in spinning mills.
  • sensor devices preferably light sensors, are arranged on the gripper carrier and monitor the filling status of the loading chutes.
  • the sensor devices are connected to the central magazine control device via signal lines.
  • the sensor devices ensure that the gripper carrier does not position the sleeve grippers in front of an empty loading shaft. This means that if the sensor device detects that the loaded feed chute no longer has an empty sleeve, the gripper carrier is moved one row of feed chutes, for example downwards, so that the relevant sleeve gripper is again in front of a filled feed chute.
  • the central magazine is advantageous Control device programmable via an input keyboard (Claim 10). That means using the input keyboard can set certain parameters for example regarding the Order of emptying the storage columns and / or their Loading shafts and the process and scope of the Supply of the winding station's own buffer memory is specified what, especially in connection with a Lot change is positive, because in this way the Downtime of the textile machine can be minimized.
  • the feed chutes each have lateral guide strips, which ensure that the sleeves roll off properly within the inclined feed chutes.
  • the orientation of the sleeves within the feed chutes is such that the sleeve center axes are approximately orthogonal to the longitudinal center axis of the feed chutes.
  • the guide strip, on which the conical sleeves bear with their smaller diameter is mounted so as to be longitudinally movable.
  • the sleeve grippers preferably also have a control lever which acts on the movable bar in the longitudinal direction with each sleeve receptacle. This means that during each sleeve removal process, the bar is aligned by means of a controlled movement against the rolling direction of the sleeves, thus immediately counteracting the beginning of the sleeve tilting.
  • a control curve on the control lever of the sleeve gripper prevents the sleeves located in the loading shaft from being acted upon when the longitudinally movable bar returns to its initial position due to the spring force.
  • the friction values of both the fixed sleeve side guides and the movable bar are also optimized.
