Abstract:
A textile machine apparatus for handling tubes having remaining yarn thereon includes a branch path for supporting tube support members, which individually support tubes thereon, for travel to and from the discharge assembly of a textile winding machine. The tube handling apparatus also includes a sensor disposed along the discharge transport path of the tube support members from the winding stations of the textile winding machine for discriminating among tubes having no yarn thereon and tubes having remaining yarn thereon. A guide member is operatively connected to the discriminating sensor for guiding the tube support members supporting tubes having remaining yarn thereon onto the branch path for transport therealong to a tube stripping device, which strips the tubes of the remaining yarn. The stripped tubes are then returned to the discharge transport path at a location upstream of the discriminating sensor. In one aspect of the invention, the discriminating sensor discriminates among tubes having less than a predetermined minimum amount of yarn thereon, tubes having more than a predetermined minimum amount of yarn thereon, and tubes having no yarn thereon.
Abstract:
A tube transport assembly is provided for individually transporting tubes of the type onto which yarn is wound on a textile machine. The tube transport assembly includes magnetic components for guiding and transporting the tube support members along a transport path by magnetic interaction with ferromagnetic portions of the tube support members. The magnetic components can be configured as electromagnets or as permanent magnets. The transport path includes a junction at which the tube support members can be individually branched onto a branch path and a magnetic component is positioned adjacent the junction for selectively magnetically engaging the tube support members to guide the tube support members along to selected branch paths. A vertical transport component includes magnetically active carrier members mounted on an endless belt and is operable to magnetically engage and carry the tube support members vertically.
Abstract:
A yarn end preparing apparatus is provided for drawing off a yarn end of a textile yarn package and thereafter rewinding the drawn out yarn end onto the yarn package at a preferred location thereon. The yarn preparing apparatus includes a suction housing supported on a pair of vertical guide rods for movement parallel to the axis of a yarn package to be prepared. A pair of linkage members, each comprising a conduit, are pivotably connected to one another with their respective conduits communicated with one another for applying suction through the conduits to the suction housing to thereby effect drawing in of a yarn end through a suction slot of the suction housing. A light beam emitting member is mounted forwardly of the suction slot for emitting a light beam detected by a light beam detecting member mounted on an opposite forward side of the suction slot. During downward movement of the suction housing to dispose the suction slot adjacent the tapered top portion of a yarn package, the light beam is interrupted by the body of yarn on the yarn package as the suction slot reaches an optimal spacing from the yarn package and a control unit stops the movement of the suction housing in response to the interruption of the light beam to automatically position the suction slot at a predetermined optimal spacing from the tapered top portion of a yarn package independent of the relative axial position of the tapered top portion.
Abstract:
In a bobbin winding machine with plural winding stations (13), a bobbin transport system for conveying bobbins to be unwound to and from the winding stations comprises a feed track (10), an oppositely located removal track (14) and plural transverse transport tracks (16) extending therebetween through an unwinding position (17) of an associated winding station. The winding station (13) has a positioning element (18), which positions and holds a transport element (11) with a spinning bobbin (12) in the unwinding position and releases it after unwinding. A device (31), preferably combined as an integral unit with the positioning element (18), is additionally associated with each transverse transport track to limit the capacity of the transverse transport track to accept only a single transport element (11) between the positioning element (18) and the removal track (14).
Abstract:
A textile package transport system utilizing transport plates for transporting spinning cops, particularly within a textile machine which produces cheeses. Each transport plate has an information storage medium in the form of a magnet of ferromagnetic material having a high retentivity encodable by selective polarization thereof. Electrically chargeable encoding coils are arranged in the transport system to selectively apply a defined polarity to the magnets. The encoding coils are actuated by way of sensor signals generated as a function of a processing status of the spinning cop and Hall sensors are utilized for detecting the respective polarity of the magnets. Controllable electric switches are disposed in the transport system for controlling the conveyance of the transport plates within the system.
Abstract:
An apparatus for pneumatically aspirating a yarn end from a spinning cop (15) with a suction nozzle (33) whose working position is adjustable has a housing (16) defining a vertical aspirating slit (19) over which a sealing belt (31) is disposed. An air passage (32) is formed in the belt (31) with the suction nozzle (33) fastened on the belt (31) about the passage (32). The belt (31) is selectively displaceable between a sealing position completely closing the aspirating slit (19) in the housing (16) and various aspirating positions wherein the air passage (32) of the belt (31) is in communication with the aspirating slit (19) of the housing (16) to apply suction through the nozzle (33) to initiate an effective, yet gentle loosening of a yarn end (46) from the conical windings (43) or the surface area of a spinning cop (41).
Abstract:
A transport system for mutually independent caddies carrying bobbins or bobbin tubes and having base plates, includes one transport path and another transport path entering the one transport path at a converging point. Moving surfaces, in particular surfaces of conveyor belts, carry the caddies along the transport paths by frictional engagement, with the caddies standing on the base plates. At least one additional contact surface is disposed at the converging point for touching a caddy passing through the converging point and imposing an additional motion component upon the caddy.
Abstract:
An apparatus for automatic rotational positioning of textile yarn winding tubes about their lengthwise axes while being transported on peg-tray tube carriers along a conveyor belt or other transport path includes a positioning station having a pair of rotatable positioning rollers disposed at the station along one side of the transport path at a sufficiently close spacing to one another to prevent passage of the peg trays therebetween. Each peg tray has a base plate whose annular surface is formed of a magnetically attractable material such as iron and at least the upstream one of the positioning rollers is magnetized to selectively exert a magnetic force on the peg trays at controllable intervals. As desired, the downstream positioning roller can also be magnetized.
