Abstract:
In an apparatus on a spinning room machine for depositing fiber sliver, a stationary delivery device for delivering fiber sliver and a substantially flat receiving support surface for receiving and collecting the fiber sliver as a can-less fiber sliver package are present. The receiving support surface, which is substantially unenclosed, is movable during the depositing process back and forth in the horizontal direction by a drive arrangement. In order to improve the production of the can-less fiber sliver package, the speed of the receiving support surface with the sliver package is alterable substantially on a reversal path such that a gradual braking to speed value zero to the speed of the back and forth movement are effected.
Abstract:
A device with a drafting device (3) for drafting at least one sliver (FB) supplied to the drafting device (3) comprises a sliver depositing apparatus (4) downstream from the drafting device (3) for depositing the drafted sliver (FB′) into a can (6). Furthermore, the device comprises a can replacement device (15) for replacing a filled can (6′) by a can (6) to be filled. Means (17) is provided on the device for lowering the temperature (T) and/or the relative moisture (LF) of the fibrous material (FB, FB′) before or after it is deposited in the can (6). Furthermore, means (17) for raising the temperature TU of the machine parts (13, 20) that make contact with the uppermost sliver layers (BL) in the filled can (6′) can be provided, with which means (17) a condensation of water on the cited machine parts (13, 20) is at least reduced. A combination of a card (1) with a drafting device (3) comprises a sliver depositing apparatus (4), downstream from the drafting device (3), for depositing the drafted sliver (FB′) into a can (6) as well as comprises a can replacement device (15). During the replacement of a filled can (6′) by a can (6) to be filled the filled can (6′) is pushed from the filling position (18) to an adjacent ejection position (19). No machine part (13, 20) covering and touching the uppermost sliver layers (BL) is provided in the ejection position (19) in order to avoid a condensation of water.
Abstract:
A device is provided on a spinning preparation machine for receiving a sliver from a discharge device of the spinning preparation machine and transporting the sliver to a downstream machine, the spinning preparation machine having a depositing region. The device has a support for receiving the sliver deposited from the discharge device in the depositing region, and a moving device for moving the deposited sliver relative to the discharge device in the depositing region for forming a free standing sliver bundle, and for moving the free standing sliver bundle out of the depositing region for transport to a downstream machine.
Abstract:
A transport apparatus for feeding textile packages used in the textile industry in two transport directions includes a first pusher element being displaceable in two transport directions and a second pusher or indexing element extending parallel to the first pusher element. A coupling device couples the elements in various positions with limited mutual movement. A reversible drive mechanism is connected to one of the elements for acting on the one element to produce a relative motion between the elements. Latch carriers for the two transport directions are movably supported on the first pusher element. The latch carriers are pivotal into a transport plane of sliver holding containers in accordance with the transport directions by the second pusher or indexing element. The latch carriers are automatically pivoted into a transport position or an idle stroke position under influence of the relative motion. A transport system may also include a plurality of the transport apparatuses and an automatic can transport vehicle may include at least one transport apparatus.
Abstract:
A system for conveying a coiler can between a sliver producing fiber processing machine and a sliver consuming fiber processing machine includes a carriage for accommodating the coiler can; an electric motor mounted on the carriage for propelling the carriage; and a battery replaceably mounted on the carriage and being electrically connected with the motor for supplying electric current thereto. The system further includes a battery replacing apparatus having a manipulating mechanism for removing a battery from and for moving a battery onto the carriage and a supporting arrangement for supporting the battery during displacement thereof by the manipulating mechanism.
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. Following transfer of the full sliver can from the transport carriage to the back row position of the spinning station, the running sliver can is returned to the front row position of the spinning station. An apparatus for use in practicing the method includes a can transport carriage having a rotating turntable with a plurality of equally angularly spaced can supports thereon.
Abstract:
The can transporting device transports the cans by using rails which are driven synchronously by crank drives. In one embodiment, the cans rest on a floorplate while the rails are moved so as to transport the cans in a forward step-wise manner along the floorplate. In non-linear arrangements, straight rails are jointed to each other by curved rails. In this embodiment, an additional crank drive is provided to support the outer curved rail for vertical movement. The transport direction of the cans can be selected through selection of the direction of rotation of a gear motor which drives the transmission for the crank drives.
Abstract:
An apparatus for transporting at least one can between a sliver furnishing fiber processing machine, e.g. a carding machine, and a sliver fed fiber processing machine, e.g. a drawing frame, by means of a transporting carriage. In order to improve loading and unloading as well as transport of the spinning cans, a loading and unloading device for the can is associated with the transporting carriage, with the loading and unloading device including conveyor elements for moving the can with respect to the transporting carriage.
Abstract:
Method of exchanging sliver cans of a spinning machine having individual spinning stations, the sliver cans being disposed in staggered array adjacent and behind one another, by means of a can exchanging device able to travel on a given travel path along the spinning machine which includes placing the sliver cans in groups of at least three cans on turntables installed below the respective spinning stations of the spinning machine, conducting the can-exchanging device with at least one filled sliver can carried thereby in operating readiness past the groups of at least three cans at the respective spinning stations, stopping at a respective spinning station in response to a signal "sliver missing" from the spinning station and automatically carrying out the following operating steps:(a) turning the turntable into can-exchanging position if the turntable is not already in such position;(b) removing from the turntable the sliver can to be exchanged;(c) delivering the filled sliver can from the can exchanging device to the turntable;(d) turning the turntable back into operating position thereof if necessary;(e) conducting the can-exchanging device to a loading station and surrendering thereto the removed sliver can;(f) and providing the can-exchanging device with another filled sliver can to be carried thereby.
