Can Changing Patents (Class 19/159A)
  • Patent number: 6161257
    Abstract: A given plurality of empty round (cylindrical) cans are brought by a can carrier into an empty can magazine of a textile machine which produces a band output. These cans are taken from the can carrier, one after another, to be filled at a filling station from whence filled cans are sequentially moved to a just emptied can carrier in a full can magazine. This can carrier, after the receipt of a given plurality of filled cans, are transported out of the full can magazine. Subsequently, the can carrier, which, in the intervening time, has been emptied and is now to be found in the empty can magazine, is transported by means of an elevated crossover into the full can magazine, which has become free. For the well-timed release of a can carrier loaded with empty cans as well as the transporting of a can carrier from the filling operation loaded with filled cans, there is a Hold Station serving as a buffer zone for an empty can with its can carrier.

  • Patent number: 5966780
    Abstract: A method for improving the monitoring of the fill state of a sliver can (5) at a spinning station of a textile machine processing sliver wherein a defined portion (24 or 124) of a can bottom (22) is initially kept free from sliver (6) while a predetermined amount of sliver (6) is deposited on an adjoining portion (25 or 125) of the can bottom (22) and only after the adjoining portion (25 or 125) is covered with sliver, is the defined portion (24 or 124) covered with sliver (6). The method includes monitoring the defined (24 or 124) portion while the sliver is being drawn out and detecting when the defined portion of the can bottom (22) is uncovered to trigger a signal for exchanging an empty can for a filled sliver can. In one preferred embodiment, a sensor (27) for monitoring the defined portion (24 or 124) and detecting an uncovered can bottom is mounted on a service unit (16) which passes over the spinning stations.

To obtain the desired rupture of the sliver, the draft of the running sliver is increased in the drawing frame to such an extent as to provide a location of reduced thickness in the running sliver. Thereupon the filled can is moved away from under the coiler head when the location of reduced thickness in the running sliver is situated in a zone of the sliver outlet of the coiler head.

  • Patent number: 5428869
    Abstract: A device for filling a series of non-circular cans, which are disposed on a conveyor, with sliver from a sliver producing textile machine. A coiler for delivering sliver to the cans is supported on an ancillary frame which is, in turn, supported for movement on a main frame. The cans are supported on the conveyor that moves past the coiler in a direction perpendicular to the long axis direction of the respective cans. A double acting piston cylinder arrangement moves the coiler and a cover over the can in which the coiler is disposed along the path of movement of the conveyor for moving the coiler over the can to be filled. The cover and can coiler together are moveable along the long axis plane of each of the cans by a drive for moving the coiler to deliver the sliver into the can.

  • Patent number: 5400476
    Abstract: The present invention provides a drafting apparatus and method having a plurality of pairs of rollers which pairs are each driven in the same rotational direction and have silver contact points oriented along a common straight line. Sliver is fed to the primary rollers through a trumpet guide connected to a strain gage to determine the size of incoming silver and adjust the draft ratio accordingly to equalize the output silver weight. A silver presence and position detecting device operative on a reflected signal is provided adjacent the output of silver, which sends a signal through a computer to adjust the speed of the silver take up apparatus.

  • Patent number: 5390484
    Abstract: A method for automatic silver can exchange operations includes the transport of full sliver cans on a sliver can transport carriage to and between the spinning stations of a textile spinning machine and is particularly suitable for the exchange of sliver cans at spinning stations of the type having a back row position for supporting a sliver can and a front row position for supporting another sliver can. In a situation in which sliver is still being drawn from the frontmost sliver can while the backmost sliver can is empty, the method includes the step of initially transferring the running sliver can to the transport carriage, positioning a can support on the transport carriage for receipt of the empty backmost sliver can, and transfer of the empty backmost sliver can. Thereafter, the method includes the step of indexing movement of a full sliver can on the transport carriage to position the can for subsequent transfer to the back row position of the spinning station.
