Yarn cone holder with yarn retention arm

Abstract

A yarn cone holder whereby the yarn cone is mounted on an angled wire section of the holder with a yarn retention arm disposed substantially below the yarn cone and extending outwardly therefrom and including a resilient pad with the lower edge of the yarn cone deforming the resilient pad.

Description

BACKGROUND OF THE INVENTION

Creels are widely used in the textile and the carpet industry on which multiple yarn cones are mounted at varying positions on the creel. Yarn is unwound from the cone and transferred to tufting, warping, weaving looms and other like-type machines. During this process, yarn is unraveled from the cardboard yarn cone at high speed which causes inherent vibration in the cone itself. This results in the strands of yarn wrapped around the cone and disposed closest to the creel post tending to slide away from the cone which can cause interference in the operation of the creel including yarn breakage and yarn tightening which requires the operator to manually reposition the yarn strands on the cone. By this invention, lower strands of yarn are maintained in position and the need for yarn end and tension detectors is eliminated.

BRIEF SUMMARY OF THE INVENTION

In textile manufacturing, multiple yarn cones are mounted on a creel by means of a yarn cone holder. As the yarn is removed from the cones, yarn wound on the lower portions of the cones tends to unravel. In order to prevent undesirable unraveling, according to this invention, a wire cone holder includes angular wire cone engaging means with the yarn cone mounted thereon and which is attached to the creel by means of an attachment bracket. A yarn retention arm including a base plate with a foam pad mounted thereon extends laterally from the cone engaging means so that the lower edge of the yarn cone depresses the resilient foam causing the foam pad to envelop the lower strands of yarn mounted on the cone and thereby maintain them in their proper position. This results in the elimination of the need for tight end detectors and motion sensors so that the machine operates at a higher production efficiency.

Over time, yarn cones tend to collapse and assume an irregular shape making it difficult to install them on a conventional wire cone holder. According to this invention, the wire cone engaging means includes a pair of angular spaced wire sections extending from an attachment bracket with the distal looped ends angled inwardly to facilitate mounting of the yarn cone even if it is substantially collapsed.

DETAILED DESCRIPTION OF THE INVENTION

In the drawings and with particular reference to FIG. 1, numeral 1 designates an upright frame member or creel post of a conventional creel with multiple vertically arranged support shafts 2 extending outwardly and generally laterally therefrom.

As shown in FIG. 3, the yarn cone holder is designated generally by the numeral 3 and includes attachment bracket 4 and wire cone engaging means 5. Wire cone engaging means 5 includes wire sections 6 and 7 the free ends of which are secured to bracket 4, as is well known. Wire sections 6 and 7 extend in a generally parallel fashion from bracket 4 outwardly and loop around through an angle substantially greater than 90 degrees whereby the ends opposite from bracket 4 are integrally joined together by connector 8. The distal looped ends of wire sections 6 and 7 are angled inwardly so that the tips are in close proximity to the point of touching or slightly separated.

According to a feature of this invention and as best shown in FIGS. 4-7, the yarn retention arm is indicated generally by the numeral 9 and includes base plate 10 and foam pad 11. Foam pad 11 is manufactured of any suitable resilient foam material and is secured to base plate 10 by means of conventional hook strips 12 and loop strips 13 adhered, respectively, to foam pad 11 and base plate 10. By this means, foam pads 11 are quickly removed and replaced, as needed, due to wear and tear. Foam pads 11 are also attachable to base plate 10 by more permanent means such as glue and the like.

In order to attach yarn retention arm 9 to creel support shaft 2, various types of brackets are utilized. One such bracket is shown in FIG. 5 in the form of a split collar bracket generally designated by the numeral 14 by which semicircular clamp 15 is secured by welding and the like to base plate 10. In order to attach retention arm 9 to support shaft 2, without the necessity of removing and replacing wire cone engaging means 5, semicircular clamp 15 is positioned around support shaft 2 and corresponding semicircular clamp 16 is placed on the opposite side of support shaft 2. Then semicircular clamps 15 and 16 are secured together by means of screws 17 and 18 so that yarn retention arm 9 is securely fastened to support shaft 2 and extends through aperture 22. By separating semicircular clamps 15 and 16, retention arm 9 is easily removed and replaced without the necessity to disassemble and remove any other elements of yarn cone holder 3.

An alternate yarn retention arm attachment means is shown in FIG. 6 by which circular bracket 19 is attached to base plate 10 by welding and the like and is provided with set screw 20. In order to install yarn retention arm 9 on the creel, it is positioned so that support shaft 2 extends through aperture 21 of circular bracket 19. Bracket 19 is then secured in place by set screw 20 and retention arm 9 is in an operational position as shown generally in FIG. 1.

Following this, yarn cone holder 3 is positioned on support shaft 2 whereby support shaft 2 extends through aperture 23 of attachment bracket 4 such that the lower surface of attachment bracket 4 is in face contacting relation with the upper surface of either circular bracket 19 or split collar bracket 14 depending on which type of bracket is being used. Attachment bracket 4 is secured to support shaft 2 by means of set screw 24 extending through an aperture formed in attachment bracket 4, as shown in FIG. 7.

Yarn cone 25 is then positioned on yarn cone holder 3 in known manner. Since the inner diameter of yarn cone 25 is less than the angular disposition of wire cone engaging means 5, the resulting outwardly biasing force on the inside of yarn cone 25 acts to maintain the yarn cone in its proper operational position on the creel, as shown in FIG. 1.

Since the lower strands of yarn 26 tend to unravel in practice, it is necessary to maintain yarn 26 from unraveling around the inner edge of yarn cone 25 which causes a tight end or break out. This is accomplished by the resiliency of foam pad 11 whereby the inner edge of yarn cone 25 closest to the creel post 1 is caused to depress foam pad 11 inwardly an amount sufficient to cause the surrounding foam to envelope and thereby hold the lower strands of yarn 26 in position.

Depending on the access limitations of the particular creel, bracket 4 is positioned so that set screw 24 is accessed from above or below and affixed to support shaft 2 by means of set screw 24.

In some applications of this invention, it is desirable to affix a second foam pad 11 to the opposite side of base plate 11, as shown in FIG. 8, so that, in effect, base plate 10 is fully enveloped in foam so as to prevent any operator injuries resulting from inadvertent contact with exposed metal parts of base plate 10.

The feature of applicant's invention of the looped distal ends of wire sections 6 and 7 being angled inwardly and touching facilitates the placement of yarn cones 25 onto wire cone engaging means because typically the cardboard yarn cones themselves tend to collapse over time which are clearly difficult to place onto conventional yarn cone holders in which the distal ends are not substantially turned inwardly.
