An automatic winder that enables the number of yarn-supplying-bobbin feeding devices to be increased easily. In an automatic winder comprising an ejection passage 2 formed therein for ejecting a bobbin conveying medium (a tray T) with a bobbin placed thereon and a feeding passage formed therein for supplying the bobbin conveying medium, the automatic winder having a plurality of installation spaces S in each of which a single winding unit U can be installed, wherein a yarn-supplying-bobbin feeding device 12 that is compatible with the winding unit U in terms with mounting dimensions is installed in an arbitrary installation space S while the winding unit U is installed in each of the other installation spaces S so that the bobbin conveying medium ejected from the winding unit U can be received by the yarn-supplying-bobbin feeding device 12 via the ejection passage 2 while the bobbin conveying medium can be supplied from the yarn-supplying-bobbin feeding device 12 to the winding unit U via the feeding passage 3. The number of yarn-supplying-bobbin feeding devices 12 can be increased easily, so that for example, the number of yarn types handled by a single automatic winder can be changed easily.

A sliver can which facilitates the location of a trailing end portion of the sliver. The sliver can includes a main body and a tubular member associated with the main body for receiving an end portion of the sliver. By positioning the end portion of the sliver in a specific area, i.e. the within tubular member, the end portion may be easily located.

A bobbin carrying tray having an air passage extending through a peg adapted for insertion in a bobbin, and through a base underlying it. Some linear members are provided at the midway portion of the air passage to prevent the passing of yarn which is suspended in a bobbin by the air drawn through the air passage.

A yarn end finding device in which a yarn end suction opening part of a suction mouth for leading out a yarn end on a surface of a yarn layer on a spinning bobbin by an action of a suction air flow can be moved on the basis of the difference in the yarn layer diameter of the spinning bobbins to be treated.

A yarn end unwinding apparatus includes a support base for supporting a yarn package in an upright disposition and a cooperating member. The cooperating member at least partially circumferentially surrounds the upright yarn package and includes a plurality of jet nozzles for directing jet streams of gas interiorly of the cooperating member. The jet streams of gas combine together to form a spiraling stream of gas which causes planetary motion of the package. The package moves in contacting relation along the inner surface of the cooperating member while simultaneously rotating about the package axis and this planetary motion of the package causes unwinding of the yarn end therefrom into position for subsequent package unwinding engagement. The support base preferably includes a pair of relatively movable semi-cylindrical portions.
摘要:
A device for finding an end of a yarn whereby an end of a yarn connecting to a layer of the yarn on a bobbin is found and is inserted into a center hole of a bobbin. The device includes an air flow controlling plate located near an outer periphery of a layer of a yarn on a spinning bobbin and a compressed air injection nozzle located in a gap between the air flow controlling plate and the yarn layer of the spinning bobbin.

A bobbin conveying apparatus comprising a plurality of trays each of which has a bobbin supporting pin insertable in the bobbin; a pair of guide rails assembled in loops for guiding the trays; a round belt running along the guide rails, the belt being kept with the bottom surfaces of the trays so that the trays are frictionally moved in accordance with the movement of the belt; a mechanism for stopping the bobbin so that the belt continues to run away from the arrested bobbin; and a bobbin take-up means for taking up the arrested bobbin from the tray.
摘要:
An apparatus for finding an end of a yarn of a spinning bobbin comprising a cutter mechanism located adjacent a path along which a spinning bobbin fitted uprightly on a tray is fed for releasing and cutting a bunch of a yarn on the bobbin, a yarn end pick-up mechanism located next to the cutter mechanism for picking up an end of the out yarn from a layer of the yarn, and a yarn end inserting mechanism located next to the yarn end pick-up mechanism for cutting the yarn end picked up frm the yarn layer into a string of a particular length and for inserting the yarn into a center hole of the bobbin.
摘要:
A device for inserting the thread end of a textile bobbin into a bobbin sleeve includes a bobbin conveyer, slip-on arbors disposed on the bobbin conveyer, each of the slip-on arbors being a tube with upper and lower open ends for receiving a bobbin sleeve thereon, a first controllable suction nozzle, a device for positioning the first suction nozzle against the lower end of one of the slip-on arbors on which a bobbin sleeve is disposed, a controllable mechanical thread stripper for stripping thread from the bobbin sleeve, a thread clamp, a second controllable suction nozzle connected to the thread stripper and to the thread clamp, a device for moving the second suction nozzle upward and downward into a stop position against the upper end of the bobbin sleeve, a controllable holding device for laterally pressing the base of the bobbin sleeve against the one slip-on arbor, a thread severing device disposed downstream of the second suction nozzle as seen in travel direction of a thread end separated from the bobbin above the bobbin sleeve, and a device for reversing the direction of suction air flow acting on the thread end separated from the bobbin for inserting the thread end into the bobbin sleeve.
