Definitions

  • the package holding device of each package is supported by a creel part extending between the end of a mounted package and the thread guide and thread brake associated therewith.
  • the package holding device is guided by the moving means so as to be linearly displaceable at least at the package area of the creel parallel to the axis of a package inserted thereon and away from the thread brake and thread guide and at the end of the aforementioned linear movement externally of the package area such package holding device can be tilted in a vertical plane, preferably through 90.
  • the present invention relates to a new and improved construction of warp creel of the type embodying supports arranged in parallelism for receiving or housing respective juxtapositioned and/or superimposed arranged thread brakes and associated thread guides, and means for moving the packages or bobbins associated with the thread brakes out of their wind-off or unwinding position in the package area together with their package holding devices for the purpose of package or bobbin exchange.
  • magazine warp creels by means of which the work is carried out continuously, for instance such as beaming or warping.
  • magazine warp creels there is provided for each thread brake and associated thread guide a respective pair of packages, wherein the start of the thread of one package is connected with the thread end of the other package of the package pair, so that after depletion of the lastmentioned package the thread jumps over the produced connection to the full firstmentioned package and now is wound-off therefrom, whereas its end is connected with the start of a new full package mounted at the location of the prior empty package.
  • Another and more specific object of the present invention is to provide an improved construction of warp creel which effectively fulfills the need of combining minimum space requirements of the creel in the lengthwise and horizontal direction and allows for good accessibility to the packages or bobbins for exchange purposes.
  • the pairs of packages associated with a thread brake are supported by a package board or shelf independently of the brake board or shelf carrying the thread brakes and guides, and in such a manner that in each case two packages are pivotably retained, for instance, at pivot arms about a common axis, wherein the pivot axes of all pivot arms are carried by supports arranged in parallelism with one another at a frame. If during operation of such creel the one package of a pair of packages is empty then the arm is moved, particularly pivoted, out of the package area, the empty package sleeve is withdrawn and replaced by a new full package. Thereafter, the new. package is again pivoted back and its thread start portion connected with the thread end of the package which is in operation.
  • creel constructions contemplate exchanging the packages externally of the creel in that the package or bobbin holding device is secured, for instance, to a pistol handle which is releasably supported at the package board provided in addition to the brake board. While such type creels render possible a very space saving arrangement of the packages, still they possess the drawback that the packages must be guided manually out of and into respectively, the package or bobbin bay. Consequently, there is present the danger of undesired contact of the packages. Additionally, there is always present the danger that during careless handling, or as a result of vibrations, packages will drop-off and damage lower situated packages. Both the large number of handles as well as the special supports at which they are detachably secured additionally disturb the facility of inspection and accessibility of such creels.
  • the package holding devices are connected with vertical uprights or supports arranged in a plane.
  • the package holding devices are pivotable about axes with respect to the vertical uprights.
  • Such axes are located in a plane parallel to the plane of the uprights, and the pivot axes of the package holding devices intersect the uprights at a downwardly open acute angle of about 35 to 50, and the plane of the pivot axes parallel to the plane of the uprights is displaced or offset in a direction leading away from the thread guides.
  • each package support rod is secured to an upright through the agency of a pivotal parallelogram.
  • This pivotal parallelogram for the purpose of exchanging the package, must be rocked out of its horizontal position in the wind-off position out of the package bay into a vertical position.
  • the package is ,moved closely past movable compo nents, constituting a great danger of possible damage and operational disturbance.
  • the large number of movable components at the direct neighborhood of the unwinding region are subjected to pronounced contamination by dust and fibers and only can be cleaned with great difi'lculty.
  • the large number of parts impairs the visual accessibility of the equipment, so that the condition of the packages only can be controlled from a close-up position.
  • the packages can be moved linearly and in a plane, namely the plane of the thread brake, in other words opposite the pay-off or withdrawal direction of a thread or the thread, out of its wind-off position in the package area and out of such package area, there is rendered possible optimum utilization of the available space, not only in the vertical direction but also in the horizontal and especially in the lengthwise direction of the creel, since the package holding devices can be arranged quite close to one another in both directions.
  • One of the prior art constructions mentioned at the outset of this disclosure further has the drawback that the package holding devices must be secured to special vertical or horizontal supports, the so-called package board or shelf, whereby additionally with known magazine holding devices oftentimes two different uprights have to work with one thread guide and thread brake respectively.
  • the so-called brake board or shelf Along with the supports necessary for the mounting of the thread guides and thread brakes, the socalled brake board or shelf, there is also present a multitude of supports and other components which impair the facility of inspection of the equipment for monitoring same from a distance.
  • the holding device of eack package is carried by that support which also carries the associated thread guide and thread brake.
  • FIG. 1 is a portion of a vertical support of a creel with four superimposed arranged thread guides and associated thread brakes and the holding devices for the packages associated with said thread guides and thread brakes, partially in different positions
  • FIG. 2 is a horizontal sectional view through a portion of a magazine warp creel with two horizontal neighboring vertical supports with a respective thread brake of the associated thread guide and the associated package pair at its holding device in the wind-off position;
  • FIG. 3 illustrates a sectional view of a package holding device in the wind-off position
  • FIG.4 is a view of the package holding device, corresponding to the showing of FIG. 3, but in the position of the components assumed for exchanging the package.
  • warp creel which has not been shown in its entirety in the drawings will be understood to comprise a large number of spaced parallel supports 1. These supports 1 can extend horizontally from one end of the creel to the other, or they can be located vertically next to one another as in the arrangement selected for the illustrated exemplary embodiment.
  • These supports 1 are formed by profile members la possessing, in cross-section, a substantially U-shaped configuration, as such is well known in the art of warp creels for the supports of thread brakes and thread guides. At oppositely situated locations of the legs 2 of these supports 1 same are provided with thread guides 3, 3 in the form of pairs of eyelets through which there is linearly guided through the hollow compartment 1b of the profile member 1a of the relevent support 1 the respective thread F withdrawn from a package or bobbin of the creel and thus braked by a double-2-plate thread brake 4 arranged in such hollow compartment.
  • a package or bobbin S is associated with each individual thread brake 4 and associated thread guide 3, 3, and in the case of a magazine warp creel of the type shown in FIG. 2, two packages or bobbins S1 and S2 are associated with each individual thread brake 4 and associated thread guide 3, 3.
  • FIG. 2 which illustrates the respective package pair S1 and S2, associated with a thread brake 4, in the wind-off position in the package or bobbin area, the thread F is paid-off the package or bobbin.
  • the thread end of the package S1 is connected by a knot K with the thread start location of the package. or bobbin S2 which serves as a reserve package.
  • the thread F jumps over, and without interruption, now is withdrawn or paid-off from the package S2.
  • the now empty package or bobbin must be replaced by a full package and its thread start point connected with the thread end of the package S2, so that when the package S2 is empty the thread can again be withdrawn or paid-off without interruption from the new package.
  • a leg 2 of the support 1 which also carries the thread brake 4 and the thread guides 3, 3, and which support 1 is associated with the relevant package or bobbin, there is welded or otherwise connected a square pipe or tubular member 5 which extends horizontally away from such support 1 toward the interior of the creel.
  • a sliding element 6, preferably formed of plastic material, is mounted non-rotatably in the square pipe 5 so as to be lengthwise displaceable.
  • At the sliding element 6 there is hingedly connected through the agency of a toggle or universal joint 7 an arm 8. This arm 8, in the position of FIG.
  • This guide sleeve 9 forms a stop by means of a part 10 which extends into the hollow compartment or space 5a of the square pipe 5, this stop preventing complete withdrawal of the sliding element 6 out of the pipe 5.
  • the arm 8 carries a grip or gripping portion 11 which extends perpendicular thereto.
  • This grip portion 11 carries a spindle 12 which extends perpendicular therefrom and therefore parallel to the arm' 8, this spindle 12 serving in conventional manner for the mounting of a package and, if desired, can carry at its free end a disk.
  • the components assume the position in the wind-off or unwinding position of the bobbin or package, as such has also been illustrated for the two lowermost packages of FIG. 1 and for all of the packages of FIG. 2.
  • the grip portion 11 of the associated package holding device is seized and withdrawn, whereby the package is initially linearly guided parallel to the axis of the package and opposite to the direction of pay-off of the thread out of the package area and out of the region of the neighboring packages located in the wind-off position.
  • the arm 8 and the sliding element 6 suspended thereat slide coaxially within the square pipe 5 until reaching the position illustrated for the uppermost package or bobbin of FIG. 1.
  • the package holding devices for both packages 81, S2 associated with the thread guide 3, 3 and thread brake 4 are secured to the support 1 in the form of a horizontal V extending towards the support 1.
  • the support 1 of the creel extending vertically and always possessing unit or assembly of thread guide, thread brake and package holding device arranged in spaced relation above one another, it would also be possible for the support to also extend horizontally and to have such units or assemblies arranged in spaced relationship adjacent one another.
  • the package holding devices additionally can be considered to be maintenance free units.
  • One need hardly fear any wear since the movable components are formed from paired plastic/metal parts.
  • the displacement and pivot mechanism In the unwinding or wind-off position of the packages the displacement and pivot mechanism is retracted into the square tube or pipe 5 and there protected against contamination by dust and fibers. In this position there are not present at any location protruding screws or edges which could hinder thread travel.
  • the package holding devices form at the same time balloon dividers or breakers between superimposed arranged packages at the wind-off position.
  • the package holder devices can be readily loaded with a single hand.
  • a warp creel for mounting thread packages at a creel package area comprising support means, thread brake means and associated thread guide means arranged at said support means, package holding means for each thread package, means cooperating with each package holding means to enable moving a package mounted at the package holding means for exchange purposes together with the package holding means out of the thread wind-off position at the package area, said cooperating moving means comprising a component of the creel extending between the end of a mounted package at the associated package holding means and the thread guide means and thread brake means associated therewith for supporting the package holding means for each package, said moving means cooperating with the associated package holding means to enable such associated package holding means to carry out a substantially linear movement at least at the package area of the creel substantially parallel to the axis of the mounted package away from the associated thread guide means and thread brake means and at the end of said linear movement allowing for downward pivoting of such package holding means externally of the package area.
  • each package holding means includes a member, a spindle intended to receive the package rigidly secured substantially perpendicular to said member, said cooperating moving means embodying an arm extending substantially perpendicularly away from said member in the direction of the spindle and sustantially parallel thereto, said creel component comprising a substantially horizontal pipe member extending away from said support means of the warp creel, said arm being nonrotatably but lengthwise displaceably mounted in the pipe member for rendering possible said linear movement, a sliding element slidably but non-rotatably arranged in the pipe member, means for hingedly connecting the arm about a pivot axis with the slidable but non-rotatable sliding element, said arm being movable into a retracted terminal position wherein the hinge connecting means is located externally of the pipe member and enables pivoting of the arm into a vertical plane about the pivot
  • said pipe member comprises a square metallic pipe, a collar located at the free end of the pipe member guiding the arm and preventing the complete departure of the sliding element out of the pipe member, said sliding element and said collar being formed of plastic.
