PHELPS 7 BY 7 v Arron/vars United States Patent 3,471,097 METHOD AND APPARATUS FOR STOPPING THE ROTATION OF A FULLY WOUND ROLL OF WEB MATERIAL Richard W. Phelps, Fulton, N.Y., assignor to The Black Clawson Company, Hamilton, Ohio, a corporation of Ohio 1 Filed Nov. 6, 1967, Ser. No. 680,815 Int. Cl. B65h 19/20, 17/08 US. Cl. 242-56 7 Claims ABSTRACT OF THE DISCLOSURE Background of the invention A fully wound rotating paper roll is commonly stopped after the paper web is transferred to a new core or spool by applying friction brake shoes against the ends of the spool supporting roll. In view of the trend towards producing, processing and winding paper at higher web speeds and in larger diameter rolls, however, the stopping of a fully wound rotating roll by breaking the spool has presented increasingly serious problems. For example, if a braking force is applied to the spol of a large diameter fully wound rotating roll, the inertia of outer wraps of the roll causes the outer wraps to rotate in advance or run ahead of the spool thereby disturbing the web tension within the roll. Frequently, therunning ahead of the outer wraps is sufiicient to cause the web to break within the roll. Then when the roll is subsequently unwound for printing or further processing, the break in the web results in additional problems such as downtime of the printing or processing machine.

Summary of the invention The present invention is directed to a simplified and dependable apparatus and method'for stopping a fully wound rotating roll of Web material and is especially suited for stopping large diameter heavy rolls having a high peripherial speed. In general, the invention is directed to the stopping of a fully wound roll by driving endless belts at the peripheral speed of the roll, moving the belts into pressure engagement with the outer surface of the roll, severing the web, and then gradually decelerating the speed of the belts while maintaining the pressure engagement between the belts and the peripheral surface of the roll. The rate of deceleration and the applied pressure of the belts against the winding roll are selected according to several factors including the roll weight, the caliper of paper and the roll speed.

As a result of stopping a rotating roll in accordance with the present invention, the relative rotation between the outer wraps and the spool is minimized and the chance of breaking the web within the roll is substantially eliminated. While the roll braking apparatus of the present invention is ideally suited for use in conjunction with a heavy duty single drum surface winder for winding large diameter heavy rolls, such as disclosed in Patent No. 2,703,683 issued to the assignee of the present invention, it is to be understood that the apparatus may be adapted for use with other types of winders such as a turret winder having multiple driven cores.

Brief description of the drawing FIGS. 1-3 show schematic views of a drum Winder incorporating a roll stopping mechanism constructed in accordance with the invention and illustrate the successive steps for transferring the web to a new spool and for stopping a fully wound rotating roll.

Description of the preferred embodiment The detailed construction and operation of the continuous winding apparatus shown schematically in FIGS. 1-3 are disclosed in the above Patent No. 2,703,683. In general, this apparatus includes a drum 10 rotatably supported by a frame 11 and driven by a variable speed drive motor 12. A guide roll 14, such as a Mt. Hope roll, is positioned ahead of the drum 10 for directing a web W of paper or other material into engagement with the outer surface of the drum 10.

An empty spool 15 is received by parallel spaced arms 16 rotatable on the axis of the drum 10 and is moved into nip relation with the drum 10 with the Web W extending through the nip. The winding operation is initiated by wrapping the leading end of the web W around an empty spool 15 supported by the arms 16 so that rotation of the drum 10 causes a roll R to wind on the spool.

After the roll R has built up to a predetermined diameter, the arms 16 are rotated clockwise, thereby lowering the winding roll R until the bearings mounted on the ends of the spool 15 engage a pair of parallel spaced rails 18 supported by the frame 11 and extending horizontally from the drum 10. As the roll R increases in diameter, its spool 15 moves horizontally along the rails 18 against the bias of pressure cylinders (not shown) which are employed to maintain a predetermined nip pressure between the winding roll R and drum 10.

In accordance with the invention, a roll stopping mechanism 25 is positioned below and between the rails 18 and includes a pair of parallel spaced rollers 26 and 28 around which are directed a plurality of laterally spaced endless flat belts 30. The roller 26 is rotatably supported by the frame 11, whereas roller 28 is supported by parallel spaced arms which are pivotable on the axis of the roller 26 and extend generally horizontally in their retracted position as shown in FIG. 1. A pair of fluid cylinders 35 are pivotally supported by the frame 11 and have piston rods connected to the arms 32 for moving the roller 28 along an arcuate path 36 and thereby moving the belts 30 between retracted positions (FIG. 1) and extended postions (FIGS. 2 and 3). The roller 26 is driven by a variable speed electrical motor 38, and the rpm. of the motor 38 is indicated by a tachometer 40.

In accordance with one method for operating the winder of the invention, when the winding roll R has built up to almost its desired diameter, the belts 30 are accelerated until their speed matches the peripheral speed of roll R as indicated by the tachometer 40. As roll R is moved away from the winding drum 10 by moving its spool 15 along the rails 18 toward the stops 42 located at the end of the rails 18, the cylinders 35 are energized to raise the arms 32 and move the belts 30- into pressure engagement with the lower portion of the rotating roll R. After the roll R leaves the drum 10, the speed of roll R decreases slightly which produces slack within the web W. The slack is formed into a loop L with the aid of a suitable air pipe 45 (FIG. 2).

After the loop L is formed, the web is severed with the air jets from the pipe 45, and the leading end of the cut web is immediately directed by the air jet around the empty spool 15 supported by the arms 16 and into the nip formed between the empty spool and the drum 10 to commence the winding of a new roll R. The motor 38 is then decelerated at a controlled uniform rate which 7 is selected according to several factors including the type of web material, the weight of the fully wound roll R, the caliper of the web W, and the peripheral speed of the roll R. As the motor 38 and belts 30 decelerate, the belts 30 are held in pressure engagement with the peripheral surface of the roll R by maintaining a predetermined pressure within the cylinder 35.

As mentioned above, an important advantage obtained by stopping the fully wound rotating roll R in accordance with the invention is that a predetermined pressure engagement is maintained between the belts 30 and the roll R and the belts 30 are decelerated at a controlled rate so that the roll R is stopped with minimum relative rotation between the outer wraps of the roll R and its supporting spool 15. As a result, the web tension within the roll is not significantly disturbed, and the chances of the web breaking within the roll are substantially eliminated. While preferably the belts 30 are brought up to matched speed with the roll R before the belts are moved into pressure contact with the roll, it is to be understood that the belts 30 may be made free-wheeling with the use of a suitable clutch and brought up to speed by engagement with the roll R, after which a controlled braking torque would be applied to the roller 26 by deceleration of the motor 38 or some other braking device.
