A transport system for spinning bobbins and bobbin tubes comprises a transport path with two essentially vertical sections and an essentially horizontal section connected therebetween. The spinning bobbins and bobbin tubes are transported on pallets whose foot portion comprises an element consisting of magnetizable material. A conveyor belt runs along the transport path at the back side of which belt stationarily arranged permanent magnets are arranged to exert magnetic forces to hold the pallets on the conveyor belt.

A cop changing and transport system for a composite ring spinning and winding machine wherein both the ring spinning machine and the winding machine have respective transport systems 2 and 3 in which circulate separate respective groups of transport pallets 25 and 26, dedicated to the respective machines. A transfer device 1 is disposed at an adjacent location between the transport systems 2 and 3, and has two adjoining transport disks 8, 9 rotating in the same direction. Cop and tube manipulating devices 42 are respectively disposed on the transport disks 8 and 9 on support columns 39 of a support structure 38, which manipulating devices are positively controlled in the course of the rotation of the transport disks 8 and 9 such that the manipulating devices continuously transfer the spinning cops 59 or the empty tubes 60 from the transport pallets of one transport system to the transport pallets of the other transport system.

Textile yarn cop changing and transport system

An assembly for transporting empty tubes and cops in a ring-spinning machine. Driven conveyor belts are disposed alongside rows of spindles disposed on both sides of the ring-spinning machine. The conveyor belts are driven for delivering empty tubes to and removing cops from the spindles, and the conveyor belts have openings formed therein at a mutual spacing approximately corresponding to half the given spindle spacing for securing arbors for alternatingly supporting empty tubes and cops. Instead of the arbors, however, at least every other opening supports a driver which engages one of a plurality of caddies at an indentation formed in a support surface thereof and entrains it along the conveyor belt. Each of the caddies carry an arbor for an empty tube and for a cop. The caddies have a length which is less than the given spindle spacing. Guide tracks extend along the conveyor belts and they guide the caddies along the conveyor belts.

An apparatus for automatically forming yarn reserve windings selectively on either end of an empty tube prior to winding a yarn package thereon utilizes a threaded spindle and spindle nut assembly for supporting one of a pair of tube clamping plates for selective longitudinal displacement of a tube clamped therebetween during rotation of the tube to place the yarn reserve windings thereon. The hand of the threaded connection between the spindle and spindle nut determines the longitudinal direction in which the tube is displaced and, in turn, determines the end of the tube about which reserve windings are to be formed. In one embodiment, the spindle and spindle nut assembly are exchangeable for a like assembly formed with opposite threads, thereby to alter the longitudinal direction of tube displacement. In another embodiment, an interiorly and exteriorly threaded bushing is interposed between the spindle and the spindle nut, to form oppositely mating threads between the bushing and the spindle and between the bushing and the nut. Set screws are provided to selectively fix the nut with respect to the bushing or, alternatively, to fix the spindle with respect to the bushing, thereby to change the longitudinal direction of tube displacement without necessitating an exchange of the spindle and nut assembly.

A transport system for transporting tube support members between textile machines includes a mobile transport unit having a plurality of superposed floorings each of which supports and guides several rows of the tube support members. An onsite transfer assembly adjacent each textile machine is operable to simultaneously load tube support members onto the parallel support paths of the mobile support unit while unloading tube support members from the parallel paths onto the textile machine. Each flooring of the mobile support unit includes a transverse support surfaces at each end of the parallel support paths onto which a newly loaded row of tube support members can be positioned for subsequent movement into the parallel support paths. Each flooring also includes an offload transverse support surface for supporting a row of the tube support members for transverse movement thereof onto an intermediate holding assembly of the onsite transfer apparatus (change assembly to apparatus above). An onload platform device is operable to move a plurality of tube support members to a selected vertical position adjacent each of the floorings of the mobile support unit for transfer of the tube support members on the onload platform device onto the onload transverse support surface of the flooring. An offload platform device is operable to receive a plurality of the tube support members which have been offloaded from one of the floorings to vertically move the tube support members to another vertical level at which the tube support members are advanced along an entry path to the textile machine.

A package carrier member is positioned under a wound package by being pivoted at the end of a support arm that in turn is pivoted at the end of an arm of a package moving mechanism that includes a translational motion gear set so that upon rotation of the positioning arm the gear set will maintain the package in translational motion to a position closely above a package handling assembly at which the positioning mechanism pivots the carrier member to withdraw it from underneath the package. During this withdrawal a stop member is positioned against the package on the side opposite the direction of carrier member withdrawal to maintain the package in position against twisting, tilting or rotating as it is being released onto the package handling assembly. A package diameter sensing mechanism in the form of a roller on the end of an arm senses the diameter of the wound package in terms of the degree of pivoting of the arm, which information is applied through a comparator to control the moving means to position the carrier member closely under the package when the package has been raised for positioning of the carrier member thereunder.

Method and apparatus for transferring packages from winding stations of

A housing is mounted on a column outwardly of a package conveyor at the rear of the machine. A pair of support arms are connected to gears of a gear assembly in the housing and extend at a downward inclination inwardly toward the machine. One of the arms is mounted above the other arm and is longer so that package supporting rods extending from the ends of the support arms will be substantially parallel in a generally horizontal plane for receipt of packages positioned thereon at the winding station. The housing is vertically movable to lower the support arms for deposit of the package onto the conveyor. The support arms pivot through arcs sufficiently long to clear the rods of the package upon raising of the housing and connected support arms into position for receipt of the next package. A synchronization shaft connects the gear assemblies at the other winding stations for synchronous operation of pivoting of the support arms, and a synchronization belt extends along the machine for synchronized raising and lowering of the housing and support arms at all of the winding stations.

Package transferring means for a textile winding machine

A reserve winding of yarn on a tube on which a cross-wound package is built. The reserve includes an end projecting from the windings and extending to provide an initial length along the surface of the tube and around which windings are formed without substantial overlapping with the windings progressing from the inward extent of the initial length of yarn toward the tube end. The reserve winding is formed by a method utilizing an apparatus that is part of a traveling service unit and includes a suction conduit centrally located in a tube clamping plate for drawing-in the end of yarn and yarn guiding and advancing elements that guide the yarn inwardly along the surface of the tube and then advance the yarn outwardly during rotation of the tube to form the non-overlapping windings. The drawn-in end of the yarn is then cut at a maximum of approximately one centimeter from the windings or is inserted into the interior of the tube.
