  • Patent number: 6055792
    Abstract: The present invention concerns a procedure for the simultaneous transportation of one group of cans (31, 310, 311) in a row from a can rack (6, 60, 61)--the cans (3) being capable of being filled with fiber band--to a frame machine (2) and/or to another textile machine (4) or to a can depot (5). The group of cans (31, 310, 311) is brought in common with the can rack (6, 60, 61) for the filling of said cans (3) into a first work station (A.sub.1) on the frame machine (2). The can rack (6, 60, 61) remains at that point during the filling of the cans (3) of this can group (31, 310, 311) until, after the filling of all the cans (3) on the can rack, the can rack (6, 60, 61) then, once again with the cans, is transported to the additional textile machine (4) or to the can depot 5.

  • 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.

  • Patent number: 5682647
    Abstract: A coiler can transporting assembly for advancing coiler cans in a transporting direction to a sliver-producing textile machine. The assembly includes coiler cans each having a bottom forming a conveying face; and a conveyor element having a discharge end and an upper transporting surface engaging the conveying face of the coiler cans when in an upright, standing position on the conveyor element. The conveying face and the transporting surface have a low friction value relative to one another. A can-stopping device is situated at a location along the conveyor element and has first and second states. In the first state the can-stopping device blocks advancement of a coiler can while the conveyor element continues to move in the transporting direction. In the second state the can-stopping device allows advancement of a coiler can therethrough.

  • Patent number: 5673461
    Abstract: A method of depositing a textile fiber sliver into flat sliver cans. The sliver is deposited in layers of loops similar in shape to cycloids produced under the action of an inner force effect of the sliver body in the flat sliver can. The force results from the combination of the rotary motion of an outlet aperture of the can coiler and of the mutual reversing rectilinear motion of the can coiler and of the flat sliver can in the direction of the longitudinal axis of the flat sliver can. The axis of rotation of the can coiler lies in the longitudinal axis of the flat sliver can. The width of the layers of the loops in the direction perpendicular to the longitudinal axis of the flat sliver can is inferior to the width of the inner space of the flat sliver can. Thus, a deflection is produced of the sliver loop towards the longitudinal walls of the flat sliver can at which there is a greater velocity of the mutual relative motion of the outlet aperture of the can coiler and of the flat sliver can.

  • Patent number: 5661947
    Abstract: The invention relates to the filling of a flat can with fiber sliver by a textile machine which delivers a fiber sliver, such as a carding machine or a draw frame, whereby the flat can is moved under a stationary, rotating rotary plate. The invention significantly reduces the costs for the required movements of the flat can as compared to the state of the art. The process according to the invention for the traversing of a flat can during the filling process at a textile machine delivering a fiber sliver is realized in that the flat can is shifted laterally by tilting of the flat can around an axis in the return path of the traversing path. In the device according to the invention, the traversing mechanism is equipped with a tilting device. For this purpose, the tilting device is provided with a tilter and an axis around which the flat can is tilted.

  • 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: 5412845
    Abstract: The invention is a process and a device for the jigging of a flat can in a textile draw frame. According to the invention, the flat can is subjected to different dynamic moments in the translational movement along the jigging path. It is a characteristic of the invention that the speed is regularly modified in proximity of the reversal points (P1, P2), i.e. in the area of the reversal paths (UW1, UW2). The jigging device is provided with a driving device which renders the constant translational movement changeable in proximity of the reversal point (P1, P2). The driving device may be a servomotor controlled by a computer which serves as the control device. In another embodiment the diving device is a different, less expensive electric motor on the drive shaft of which belt pulleys capable of being coupled are installed.

  • 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: 5377385
    Abstract: An autoleveller draw frame achieves changes in the draft by changing the supply speed. The can press nevertheless works evenly. A storage device between the sliver calenders and the can press compensates for changes in the amount of supplied sliver. The storage device can be arranged in such a way that it allows a "flying change of cans." In one aspect, between the sliver calenders and the can press, the sliver forms a hanging loop which varies in depth, depending upon any changes in the supply speed of the sliver, while the can press operates relatively evenly and is not required to be accelerated or braked in response to changes in the supply speed. In another aspect, the storage device includes a conveyor belt arrangement between the supply of the sliver and the can press. Sliver loops are formed on an upper conveyor belt strand, whereafter they are deflected to a lower conveyor belt strand and then fed to the can press.

  • Patent number: 5285553
    Abstract: An apparatus for depositing sliver in a can. The sliver is introduced from above and is deposited continuously in the can in layers one above the other from bottom to top. The sliver is guided by a guiding device. The device includes rollers contained by an annular device. At least one of the rollers has a conical shape. The rollers make contact with and draw the sliver into the can. The guiding device includes a funnel which is movable in a radial direction such that the sliver is deposited in successive spiral paths in the can. A counterbalancing device is provided so as to counteract the movement of the funnel. The sliver is guided such that the spiral path runs alternately from an outer radial position to an inner radial position approximately adjacent the can center and from the inner radial position to the outer radial position adjacent an inner wall of the can.
