TEXTILE DEVICE Svend A. Petersen, Brooklyn, and Ho Chow, New York, N. Y., assignors to Celanese Corporation of America, New York, N. Y., a corporation of Delaware Application February 4, 1953, Serial No. 335,013
20 Claims. (Cl. 242-72) This invention relates to a textile device for use in yarn winding machinery, and relates more particularly to a mandrel for a yarn Winding machine on which a yarn package support is mounted for rotation.
In the winding of yarns on tubular yarn package supports, or tubes, it is customary to employ a mandrel rotatably mounted on a suitable support and provided with means for gripping the tube, which tube is generally A tube is placed on the mandrel and the gripping means thereof are moved into engagement with the tube to hold it firmly on the mandrel. After this loading or donning operation, the tube is rotated to wind yarn thereon by placing a driven rotating roller into contact with the outside of the tube and, subsequently, with the layers of yarn Wound on the tube. When the winding operation is completed, the driven roller is moved away from the wound tubeand the rotation of the tube and mandrel is stopped. The wound tube is then unloaded or dofied from the mandrel by releasing the gripping means from contact with the tube and then removing the tube from the mandrel. The mandrels used in the prior art have been diflicult to load and unload and have necessitated many time-consuming operations on the part of the operator in placing the tube on the mandrel, effecting the engagement of the gripping means with the tube, releasing the gripping means and removing the tube from the mandrel.
It is an object of this invention to provide a new and improved mandrel for yarn package supports which will be free from these and other difficulties.
A further object of this invention is the provision of a novel mandrel for yarn tubes which is easily and rapidly loaded and unloaded.
Other objects of this invention will be apparent from the following description and claims.
According to this invention, the mandrel fora yarn tube comprises a member mounted for rotation having gripping means and means for forcing said gripping means into engagement with the yarn tube. The mandrel is also provided with means for holding said forcing means in inoperative position and with means, adapted to be engaged and moved by the yarn tube when said tube is being loaded onto the mandrel, for actuating said holding means to release the same whereby the gripping means may be moved into engagement with the yarn tube to grip the latter firmly.
More particularly the mandrel of this invention comprises a barrel mounted for free rotation on an arbor. Slidably mounted on this barrel is a member having a collar and a tapered resilient skirt which is adapted to be engaged and moved by one end of the yarn tube as Such movement of p the skirt and collar is opposed by a spring mounted the tube is slipped over the barrel.
on the barrel. Also mounted on the barrel is a sleeve having an expansible portion. One end of the sleeve is fixed to the barrel, while the other and expansible end of the sleeveis compose'dof a plurality of fingers provided with roughened'outer surfaces and with inwardly nited States Patent Patented Feb. 7, 1956 directed flanges. These flanges are adapted to be engaged by a cam surface of a cup-shaped cap which is slidably mounted on the barrel. Another spring, mounted on the barrel, pushes the cap in a direction to cause the cam surface to move the flanges outwardly, thus expanding the sleeve and forcing the roughened surfaces of the fingers of the sleeve into gripping engagement with an inner surface of the yarn tube.
When no yarn tube is mounted on the mandrel, the cap is normally maintained in a position in which it is prevented from moving in a direction to expand the sleeve, being locked in this inoperative position by a shoulder at the head end of a rockable lever. When the lever is in its locking position its head end is located in a groove in the cap with its shoulder engaging a shoulder of said groove, which is situated near the rim of the cap. When there is movement of the cap relative to the head end of the lever the shoulder of the groove is adapted to rock the lever out of its locking position by forcing said head end out of the groove and onto the rim of the cap. The lever is retained in its locking position by the engagement of the tail end of the lever with a portion of the slidable collar. When the collar is moved by the yarn tube during the loading operation it is moved away from the tail end of the lever, thereby allowing the lever to rock out of its locking position, thus'permitting the cap spring to push the cap in a direction to expand the expansible sleeve. The construction and arrangement is such that this rocking movement of the lever places the tail end of the lever in front of the free edge of the collar, thereby blocking the tendency for the return of the collar to its original position in response to the action of the collar spring.
The cap is generally mounted to project beyond the free end of the yarn tube, that is, beyond the end of the tube which is engaged by the expansible end of the sleeve, and is provided with another cam surface adapted to engage the head end of the lever and rock the lever into its locking position when the cap is moved manually to its inoperative position. Such rocking of the lever also moves its tail end away from the free edge of the collar, allowing the collar to move and to partially eject the yarn tube from the mandrel. Thus, removal of a fully wound tube from the mandrel requires only a simple continuous motion of one hand of the operator. The hand of the operator, in approaching the end of the tube, engages and pushes the protruding cap inwardly to its inoperative position, thereby releasing the tube from the mandrel and causing one end of the tube to be moved off the mandrel. The operator grasps this end of the tube and slides the tube entirely oif the mandrel.
In the accompanying drawing which illustrates certain preferred embodiments of this invention,
Fig. l is an elevational view, partly in section, showing the position of the parts of the mandrel before the yarn tube is loaded thereon, and
Fig. 2 is an elevational view, partly in section, showing the position of the parts of the mandrel when the yarn tube is loaded thereon.
Like reference numerals indicate like parts in both views of the drawing.
In the drawing, reference numeral 10 indicates generally a rotatable mandrel adapted to support a yarn tube 11, shown in dotted lines, for rotation therewith. In order to place tube 11 on mandrel 10 the tube is slipped overthe mandrel from right to left, as viewed in the drawing. The mandrel 10 comprises a barrel 12 supported for free rotation on an arbor 13 by any suitable means, such as ball bearings 14 and 16 mounted near opposite ends of said barrel. A member 17 is slidably mounted on the barrel 12. This member 17 has an integral collar 18 engaging the barrel and, integral into contact with said yarn tube, and second resilient means adapted to oppose the movement of said releasing means. V
