A CORPORATION 0F NEW YORK DELIVERY HECHANISM FOR PAPER RLIS IN PAPER MAKING MACHINES Application led October 15, 1927. Serial No. 226,353.

This invention relates to certain improvements in roll handling mechanisms for paper winding machines. l

In paperl winding machines, particularly f those used for winding the large web rolls produced by Fourdrinier and like paper making machines, the rolls are wound on a spindle` in a winding mechanism, which consists of a pair of driven Winding rolls, around one of which the'web passes, lthe web roll resti Where lit may be .prepared for shipment or otherwise handled. Ordinarily the web rolls are lifted from the winding mechanism by suitable devices taking hold of the core or spindle. In large paper makingv machines where the web rolls are wide, particularly those producing web rolls for ynev'vs print,

the rollsvare Vvery. large and heavy, and liftv ing them from the Winder by Ymeans of-overhead hoisting apparatus takes" up a great amount of time and isfundesirable for other reasons. Furthermore, the spindle onwhich the paper is wound is limited in diameter and "is, therefore, not suiiiciently rigid to afford a satisfactory means for `lifting the rolls, particularly .with vvideI rolls.v

Furthermore, itisimportant in fast paper Imaking machines vthat the time 'consumed-in .35 y 'the way as rapidly as the paper is produced.

handlingv the -rolls be reduced as far as possible, so that the Vrolls maybe gotten out of It is the especial object of the present invention to produce a simple construction for delivering the webv rollifromthe winding mechanism, in Vwhich the `roll is pushed olf the Winder onto a receiver'fromwhich it may j be delivered in any suitable manner.

l-A `further object ofthe invention is to produce such a' construction which can Vbe readily. andeasily operated, and which shall re- ,Y quire a minimum amount o f space.

lWith-these and other objects not specificalv` ly referred to in view,'th e invention consists incertain novel parts,- arrangements and combinatlons which will be described in connection'with the accompanying drawings and thev novel features pointed out in the claims hereunto annexed.

In these drawings,-

. Figure 1 is a plan view of the improved delivery mechanism, and

Figure 2 is a side View, partly in section, of the construction shown in Figurel.

Referring now to these drawings, the invention consists generally in the provision of a receiver located, preferably, at one side of the Winder mechanism, in combination with a pushing device which acts to push the web roll from the Winder onto the receiver, the receiver being thereafter operated to deliver the roll in any desired manner. While the specific embodiment of the invention may vary widely, in the particular construction illustrated there is shown a Winder, mechanism of n conventional form including side frames 1, 2, and a pair of winding'rolls or drums 3, 4 suitably journalled in the frames, these drums being driven drums rotated in any suitable manner by mechanism not illustrated. The web of paper W, as it comes from the paper making machine, is Wound into a web roll 5 on a spindle 5', the roll being wound by the. winding drums in the usual manner.

. In accordance lwith `the invention, the mechanism for pushing the web' roll oif the winding' drums onto th receiver is located closely adjacent the Winder drums and, preferably, at the long side of the web roll. ,While the pushing mechanism may varysomewhat in construction, a simple one is that shown,

in which there is provided a shaft 6 suitably supported in, the side frames, which shaft is provided with a number of arms 7, 8, in which are supported a pair of pushing spools or discs 9, 10. This shaft is rotatedthrough suitable gearing, indicated at 11, from a m0- tor 12; On the rotation of the shaft in the direction of" arrow a in Figure 2, the pushing pushing it from its position on the drums`i'3`,\95

In the particular construction illustrated, this receiver is in the form of a number of cradle arms 14, 15, which preferably have curved In the particular construction illustrated,

the roll is lowered by the cradle arms to the floor level, indicated by the letter F, where the web roll may be moved away for subsequentv handling. Any suitable means may be employed for operating the rock-shaft to cause the arms to deliver the web rolls, but

in the referred construction these means will be suc that the cradle arms after delivering a web roll will return to a position to receive .asuccessive web roll. In the particular con- The operation of the device will beclear ,winding machines, the combmation with.

from the foregoing Adescription but may be `briefly summarized as follows:

Whenthe roll 5 has reached the desired diameter, the web is severed in the usual manner, and the shaft 6 is rotated by th-emotor 12 through one revolution, which pushes the roll 5 from the drums 3, 4 onto the receiver 13,.by means of the spools or discs 9, 10. The shaft having made a complete revolution comes to rest in its original position. The operator then causes the movement of the rock-shaft 17, which moves the cradle arms from the position shown in full lines in Figure 2 to the position shown in dotted lines, where the web roll 5 is deliveredonto the Hoor. When the parts have reached this position, the reverslng switch stops the rotationof the shaft to the right and causes its rotation to the left to bring the cradle armsv back to the position shown in full lines in Figure 2. It will be understood, of course, that a limit switch isA or may be employed for stopping the motor 12 after it has caused one rotation of the shaft 6,. f

With -this construction therefore, the web rolls may be readily and quickly removed from the winding mechanism and delivered as desired without-the necessity of overhead hoist or the use of the spindle for manipulating the rolls. c

While. the invention has been shown and described in its preferred form, it will be understood that various changes -maybe made in the specific construction and operation of the parts without departing from ,the invennexed.
