Definitions

  • the invention relates to a roving bobbin wagon with means for removing at least one full roving bobbin from a transport device containing roving bobbins, with means for receiving and holding the beginning of the roving of the full roving bobbin and with means for removing at least one empty roving bobbin from a creel of a spinning machine and for insertion the at least one full roving spool into the creel, the at least one full roving spool being removed from the transport device by a manipulator.
  • two manipulators are provided as means for removing the full roving bobbins from the transport device and for removing the empty roving bobbins from a creel, one of which removes the full roving bobbins from the transport device. transferred to a position within the roving bobbin changing carriage, in which means for receiving and holding the beginning of the roving the full roving bobbin can be delivered, and which then inserts the full roving bobbin into the creel.
  • the second manipulator removes the empty bobbin tube from the gate and transfers it to the transport device.
  • the movement mechanisms of the two manipulators must be designed so that the full roving bobbin and the empty bobbin tube can be guided past one another during the work.
  • the roving bobbin changer has a manipulator which carries out the replacement of full roving bobbins fed on a transport device for empty roving bobbins hanging from the gate of the spinning machine.
  • the manipulator has a receiving device for receiving full or empty roving bobbins and is designed to be pivotable and adjustable in height.
  • a plurality of receiving elements for roving bobbins arranged in a row are provided on the receiving device.
  • a receiving device for roving bobbins or roving bobbin sleeves is provided in the roving bobbin changing carriage, which serves as a buffer during the changing-in process, so that all work can be carried out with only one manipulator.
  • the invention has for its object to provide a roving bobbin changing carriage of the type mentioned in such a way that a simplified construction is obtained and the beginning of the roving of the new roving bobbin is found and made available quickly and safely.
  • the manipulator transfers the at least one full roving spool to a preparation station temporarily storing it, the means for receiving and holding the beginning of the roving at the preparation station containing at least one full roving spool, which takes the at least one empty roving spool from the creel and takes it on the transport device transfers and which then takes over the at least one prepared roving bobbin from the preparation station and inserts it into the creel.
  • the roving bobbin changing carriage according to the invention has the advantage that only one manipulator is necessary, which both removes the full roving bobbins from the transport device and transfers them to the gate and also removes the empty bobbin tubes from the gate and transfers them to the transport device.
  • the full roving bobbins are temporarily stored in a preparation station and prepared in such a way that the beginning of the new roving is picked up and kept ready. Since the means for receiving and holding the beginning of the roving of the full roving spool belong to the preparation station, no complex constructions have to be provided in order to deliver them to the roving spool. Rather, the roving spool is delivered to these funds.
  • An advantageous embodiment provides that a manipulator is provided to replace the at least one full roving bobbin with at least one empty roving bobbin, which is equipped with a gripper which grips the beginning of the roving when the at least one full roving bobbin is taken over from the preparation station.
  • a further simplification of the structural design of the roving bobbin changing carriage is achieved in that only one manipulator is provided for the replacement of the at least one full roving bobbin with at least one empty (or almost empty) roving bobbin. In particular, there is no need to move several manipulators together.
  • the only manipulator provided in the subject matter of the invention enables gripping at least one full roving spool from the transport device, transferring it to the preparation station in the roving spool changing carriage, removing at least one empty roving spool from a creel of the spinning machine and inserting the at least one full roving spool into the creel.
  • Two manipulated gates can be arranged with the manipulator rows of a ring spinning machine can be controlled. Additional devices on the ring spinning machine, by means of which the roving bobbins of the two creel rows swap places, can be omitted.
  • the preparation station is arranged to be pivotable. This makes it possible for the preparation station to be pivotable out of the lifting plane of the manipulator.
  • the manipulator can hereby be delivered with a simple lifting movement in the vertical direction of the transport device. This reduces the control effort for the manipulator.
  • the preparation station for receiving at least one full roving bobbin has a receiving device on which at least one receiving element is provided for hanging receiving at least one full roving bobbin.
  • the hanging holder of the full roving spool facilitates the transfer from the manipulator to the preparation station. Furthermore, this arrangement ensures that the space requirement is particularly small.
  • the receiving element is arranged on a shaft which is rotatably mounted on the receiving device and to which a drive is assigned.
  • the rotatably drivable receiving element enables the at least one full roving bobbin to rotate about its longitudinal axis. This makes it easier to find the beginning of the roving of the full roving spool.
  • the means for receiving the beginning of the roving of the full roving spool are designed as a suction tube which contains a suction opening for sucking the beginning of the roving.
  • the suction tube arranged stationary at the preparation station sucks the beginning of the roving at its suction opening during the rotation of the full roving spool about its longitudinal axis.
  • the suction opening of the suction tube is arranged at a height which is arranged in a preceding process (flyer) in accordance with the storage height of the beginning of the roving.
  • suction pipe is arranged in the area of the receiving element.
  • the suction tube is formed with a suction opening which can be pivoted away from the roving spool held on the receiving element by means of a drive.
  • the pivoting movement of the suction opening is only initiated after the beginning of the roving has been found and sucked in.
  • the suction opening is swung away, the drawn roving start is removed from the full roving spool. In this position, gripping the beginning of the roving is made easier by the gripper.
  • the suction pipe is approximately Z-shaped with a straight elongated Z-leg, at the end region of which the suction opening is arranged.
  • the straight, elongated Z-leg is guided in the direction of the longitudinal axis of the full roving bobbin arranged on the receiving element.

  • the suction opening which is located in the immediate vicinity of the full roving bobbin held on the receiving element during the finding and suctioning of the beginning of the roving, is pivoted away from the latter.
  • the initial region of the roving of the full roving spool is stretched between the suction opening of the suction tube and the full roving spool.
  • the means for keeping the beginning of the roving ready are designed as a rod-shaped counter-holder which contains a deflection guide for the roving.
  • the rod-shaped counter-holder arranged at the preparation station guides with its deflection guide the beginning of the roving entering the suction opening of the suction tube. A particularly precise positioning of the initial region of the roving for the gripping device is hereby achieved.
  • the counter-holder is arranged such that it can rotate relative to the roving bobbin held on the receiving element and is assigned to a drive.
  • the suction pipe and the counter holder are arranged on the receiving device so that they can be pivoted in opposite directions.
  • the starting area of the roving of the full roving spool can be brought into a position which is particularly favorable for the takeover by the gripping device.
  • the simultaneous sequence of the pivoting movement of the counter holder and the suction tube reduces the time required to prepare the beginning of the roving.
  • An advantageous embodiment of this embodiment provides that the intake manifold and the counterholder are assigned a gear arrangement which enters a counter-rotating movement and is connected to a drive. This makes the design structure particularly simple.
