6 Claims.

This invention relates to a device for handling yarn packages, particularly packages which are mounted upon a removable mandrel which is taken from the winding machine as a preliminary step for removing the yarn package from the mandrel.

It is usual to mount a hollow tubular core upon a mandrel and then to wind yarn upon this core in the formation of a suitable package. The mandrel and package are then lifted from their guide bearing and the package is removed from the mandrel, usually by manipulating some member at one end while holding the package in the hand of the operator. The grasping of the package by the operator for this release of the package frequently soils or abuses the yarn on the outer layers of the package.

One of the objects of this invention is to provide a means for handling the yarn so that it will be unnecessary to touch the yarn with the hand for releasing the yarn package from the mandrel and removing it therefrom.

Another object of the invention is to provide an arrangement so that the mandrel with the yarn package thereon may be grasped at one end without touching the yarn and then this mandrel with the package thereon placed axially in alignment with an upstanding post with such releasing means as is provided for the mandrel engaging in a holding arrangement on the end of the post so that by merely turning the part grasped by the hand when the mandrel is in this position will cause a release of the package from the mandrel and allow the package to drop over the post downwardly against the base or support from which the post extends so that the package is transferred from the mandrel into a position on the post and there properly supported.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. 1 is a top plan View of a base with a plurality of posts upstanding therefrom for the receipt of the yarn packages in an assembly for convenient handling.

Fig. 2 is a side elevation with one of the yarn packages omitted from a post and this post broken away and partly in section.

Fig. 3 is a sectional View of the mandrel and package.

Fig. 4 is a perspective View of a iragmental part of the base with a post upstanding therefrom and showing a package as dropped down over the post.

Fig. 5 is a sectional view illustrating the'package on the mandrel and in a position just prior to discharge of the package from the mandrel to drop over the post.

Fig. 6 is a sectional View through the package and mandrel;

Fig. 'l is a perspective View of a fragmental portion of the base and the post alone.

In proceeding with this invention, I provide a mandrel having a thumb nut at one end which upon manipulation will release the package so that it will fall from the mandrel, while at the other end there is a head which may be grasped for holding the assembly if desired. I also provide a base with a plurality of upstanding posts each slotted at its end to receive the thumb nut on the mandrel so that if the thumb nut is received in the slot at the end of the post and the mandrel turned, the nut will be turned relative tothe spindie, the mandrel contracted so that the core of the package will drop down over the post.

With reference to the drawings, l@ designates a base of any suitable material and of a thickness to be rigid and self-supporting. Upstanding from this base there are a plurality of posts Il which will be secured to the base by any suitable means, such for instance as at hole I2 in the base and a pin I3 on the post il extending downwardly into the base l0, thus permitting the post to be removed and interchanged with posts of diierent diameters if desired. Each of these posts Il is provided with slots l and l5 extending right angularly to each other across the end of the postA and of a depth to receive the releasing member of the mandrel.

The mandrel is shown in section in Fig. 3 and is the subject of a separate application led February 16, 1942, Serial No. 431,115. It consists essentially of body 2l consisting of three segments assembled about the spindle 2B with the ends tapered as at 22 and 23 to lit the tapered portion 24 of the head 25 fixed to the spindle at one end and fit the tapered portion 26 of the washer 2l slideable along the spindle 20 at the other end. Threads 28 are provided on the spindle and a member consisting of a thumb nut 29 threadingly engages this portion of the spindle and through means of a metal washer 30 will serve to force the washer 21 inwardly to expand the segments 2| of the body of the mandrel While spring wires 3l lodged in grooves 32 in the mandrel serve to contract these segments and force the Washer 21 outwardly as the thumb nut or member 29 moves outwardly on the spindle.

The yarn package core 33 consisting of a tubular cylindrical member is gripped by expansion of the body segments and is adapted to have wound thereon yarn 34 which will be wound on this core to the proper diameter.

When the yarn package is full the operator will grip the head 25 in his hand and then place this entire assembly of mandrel and yarn package axially in alignment with the post H as shown in Fig. while gripping the head 25 with the thumb nut 29 positioned into the slot either E4 or l5 and then by rotation of this head 25 which is xed to the spindle will cause a relative rotation of the thumb nut 29 and the spindle to move the thumb nut outwardly on the threads 28. Spring wires 3l will cause a contraction of the segments, thus releasing the core 33 and permit this core to drop axially over the post Il from the position shown by full lines in Fig. 5 to the dotted line position shown in Fig. 5. Thus this yarn package will be positioned on the post such as shown in Fig. 4.

As each yarn package is dropped over the post in this manner there will be assembled upon the several posts of the device a group of packages. The size of the group will depend upon the size of the base and number of posts thereon, all without it being necessary for the operator to touch yarn or use but one hand in a picking up of the mandrel and its package from the machine and a discharge of this yarn packonto a suitable asssembly device ready for transporting the yarn in the desired number of assembled units on the device from one place to another.

I claim:

1. A receiving device for a yarn package, which is mounted on and secured to an expansible mandrel having means thereon movable relative to said package to release said mandrel from an expanded condition to permit contraction thereof to permit removal of said package therefrom, extending therefrom of a dimension to receive said package therein, means in the upper end of said post for cooperation with the releasing means to permit relative rotation of said means to release said mandrel from expanded condi-v tion to permit renewal of said package from said mandrel for mounting the same onto said post.
