Abstract

In order to facilitate the doffing of packages wound on a spindle carrying a mandrel, and particularly packages wound in the form of successive layers of figure-8s in which the crossovers of the figure-8s progress around the package and a radial opening is provided extending from the outside of the package into the axial opening thereof, through which the free inner end of the material is led out, a shaft is provided having a sleeve slidable thereon on which a mandrel is placed for forming the winding. The shaft has at its free end extending from the machine a part pivoted thereon, and stop mechanism on such extending part to limit movement of the sleeve. By sliding the sleeve outwardly after a wind has been completed, beyond the pivot, the sleeve can drop down to a vertical position, so that the package formed on it can drop off into a box or onto a conveyor.

Gilreath 57 ABSTRACT In order to facilitate the doffing of packages wound on a spindle carrying a mandrel, and particularly packages wound in the form of successive layers of figure- 8s in which the cross overs of the figure-8s progress around the package and a radial opening is provided extending from the outside of the package into the axial opening thereof, through which the free inner end of the material is led out, a shaft is provided having a sleeve slidable thereon on which a mandrel is placed for forming the winding. The shaft has at its free end extending from the machine a part pivoted thereon, and stop mechanism on such extending part to limit movement of the sleeve. By sliding the sleeve outwardly after a wind has been completed, beyond the pivot, the sleeye can drop down to a vertical position, so that the package formed on it can drop off into a box or onto a conveyor.
2 Claims, 3 Drawing Figures ARRANGEMENT FOR DOFFING PACKAGES WOUND ON A SPINDLE CARRYING A MANDREL BACKGROUND OF THE INVENTION 1. Field of the Invention V The invention relates to a device for doffing wound packages of flexible material wound on a horizontal spindle, and particularly packages of the universal type having a radial opening extending from the outside into the axial opening.
2. The Prior Art Machines are well known, for example in Taylor U.S. Pat. No. 2,767,938, for winding packages of flexible material in a series of figure-8s with cross-overs progressing around the package, and with a radial opening extending from the outside into the axial opening. The winding spindles of these machines are normally horizontal. This presents the problem that, at the end of the winding of a package, and after collapse of the mandrel, which may be of the type shown in application Ser. No. 440,875, filed Feb. 8, 1974, the package must be removed manually from the mandrel. This presents particular problems in winding packages of fairly heavy material, which may weight 60 pounds or more, and requires the employment of persons able to handle such weights. Furthermore, dropping of the package during its removal may cause damage to the winds which will prevent proper payout.
SUMMARY OF THE INVENTION The present invention provides a device which allows the doffing of the package after it is wound without requiring the lifting of a heavy weight. More particularly, the invention contemplates the use, in a machine which employs a horizontal winding shaft or spindle, of a sleeve slidable on the spindle for receiving the mandrel, and a part pivoted at the free end of the winding spindle which is pivotally connected thereto about a horizontal axis, and has stop means thereon to limit the outward movement of the sleeve. By sliding the sleeve beyond this pivot, it can move down into a vertical position, so that when the mandrel is contracted the package will drop off and can be either loaded directly into a box or placed on a conveyor.
BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:
FIG. 1 shows in side elevation with parts in section, a doffing shaft embodying the invention;
FIG. 2 is a top plan view thereof; and
FIG. 3 shows the device in doffing position.
DESCRIPTION OF THE PREFERRED EMBODIMENTS In the arrangement shown, there is a horizontal shaft 2 comprising the spindle shaft of a winding machine, which is also provided with a guide which is reciprocated along the spindle in the proper phase relationship 2 thereto to produce the desired winding. On this shaft is secured by a pin 4 a clutch member 6 having notches 8 therein.
A sleeve 10 is slidably mounted on the shaft 2, with a space 12 therebetween. The sleeve is mounted at its inner end on the shaft by a clutch member 14 which has a part bearing directly on the shaft and is secured to the sleeve by pins 16. The member 14 has projections 18 which are engageable in the notches 8 to clutch the sleeve to the shaft through the clutch member 6.
At its other end, the shaft carries a fork 20, in which engages a projecting portion 22 of a shaft extension member 24. The part 22 is secured in the fork 20 by a horizontal pin 26. The part 24 carries a fixed sleeve 28 secured on it by pins 30 on which the sleeve 10 slides, and forms the outer support for the free end of the sleeve.
In the form shown here, the sleeve 10 supports a winding mandrel having a central portion 32 which may have spherical end portions and a cylindrical central portion, and removable end forms 34 which have outwardly flaring inner surfaces. The mandrel may be a collapsible one of the type shown in application Ser. No. 440,875 filed Feb. 8, 1974.
In the use of the device, during winding the sleeve 10 is pushed in completely so that the projections 18 engage in the notches 8. After the package is completed, the outer end form 34 is removed, and the sleeve is slid outwardly until its innermost end passes the pivot 26, where the member 14 engages the sleeve 28, thereby limiting further outward movement of the sleeve. The sleeve then drops down to the position shown in FIG. 3, the mandrel is collapsed and the package will drop off into a container or onto a conveyor or the like.
The projection of the shaft 2, and the location of the pin 26, must be great enough so that, when the device falls to the position shown in FIG. 3, the inner end form 34 will not strike the body of the machine.
I claim:
1. In combination with a horizontal winding spindle, a sleeve slidably mounted on the spindle for movement between inner and outer positions for receiving a winding mandrel, clutch means for connecting the sleeve to the spindle for rotation therewith in the inner position of the sleeve, a part pivoted on the free end of the spindle, and cooperating stop means on said part carried by the sleeve and by said part to limit movement of the spindle away from the clutch means to its outer position at a point which permits the sleeve and the part to swing downwardly with respect to the spindle to permit the doffmg of a winding carried by the mandrel.
2. In a device as claimed in claim 1, such spindle having at its end adjacent the clutch means a member secured therein and having a shoulder on the side remote from the clutch means, and said part and said member constituting the means for limiting the outward movement of the sleeve.

Claims (2)

1. In combination with a horizontal winding spindle, a sleeve slidably mounted on the spindle for movement between inner and outer positions for receiving a winding mandrel, clutch means for connecting the sleeve to the spindle for rotation therewith in the inner position of the sleeve, a part pivoted on the free end of the spindle, and cooperating stop means on said part carried by the sleeve and by said part to limit movement of the spindle away from the clutch means to its outer position at a point which permits the sleeve and the part to swing downwardly with respect to the spindle to permit the doffing of a winding carried by the mandrel.
2. In a device as claimed in claim 1, such spindle having at its end adjacent the clutch means a member secured therein and having a shoulder on the side remote from the clutch means, and said part and said member constituting the means for limiting the outward movement of the sleeve.
