MafdJZZaazA Qzgz'az Z f 7 ATTORNEYS United States Patent 3,373,952 DRUM WINDER FOR PAPER AND THE LIKE Edward J. Klaczkiewicz, Wilmington, Del., assignor to Beloit Eastern Corporation, Downingtown, Pa., a corporation of Delaware Filed Jan. 7, 1966, Ser. No. 519,206 13 Claims. (Cl. 242-66) This invention relates to improvements in drum winders for paper and the like.

A principal object of the present invention is to improve upon the drum winders heretofore in use for rewinding paper and the like, by simplifying adjustability and maintenance of the winder and increasing the efficiency thereof by improving upon the slides and supports for the core shaft for the roll of paper,

Another object of the invention is to provide a new and improved drum winder for rewinding paper and the like, in which the usual cantilevered core shaft slides are replaced by slides slidably supported along opposite sides of the center of the core shaft, and thereby providing a greater thrust capacity for-the core shaft and restriction in the end play of the shaft.

A still further object of the invention is to provide a novel and improved drum winder for rewinding paper and the like, in which the core shaft is rotatably supported intermediate the guides for the core shaft slides and a brake means is provided, controlling ascent of the core shaft slides and simplifying the adjustability and replacement of the core shaft.

Still another object of the invention is to improve upon the drum winders for rewinding paper and the like by slidably guiding the core slides along opposite sides of the slides and suspending the slides from the centers thereof, and providing detachable chucks for the core shaft, the centers of which are in alignment with the lines of suspension thereof and intermediate the guides for the slides to simplify the replacement and adjustability of the core shaft.

Still another object of the invention is to provide a simple and improved form of drum Winder in which core shaft slides slidably supported equal distances from the center of the core shaft, replace the usual cantilever slides, in which a control shaft for the slides ties the slides for movement together and is controlled by a brake, controlling ascent of the core shaft slides, and in which fluid pressure cylinder and piston means are provided for ad justably moving the slides, and interlocked with the brake for the control shaft for the slides.

A still further object of the invention is to provide a novel and improved control for the rider roll of a drum winder having a simple and improved form of counterweight which may readily be filled with shot to the extent required to counterbalance the rider roll.

Still another object of the invention is to improve upon I the rider roll supports and counterweighting means for drum winders heretofore in use by supporting the rider roll in slides slidably supported on opposite sides of the rider roll and vertically moved by fluid pressure operated cylinder and piston means at each end of the rider roll, in which counterweights in the form of upwardly opening receptacles are mounted on the cylinder and piston means and may readily be loaded with shot and the like, to counterbalance the rider roll.

These and other objects of the invention will appear from time to time as the following specification proceeds and with reference to the accompanying drawings wherein:

FIGURE 1 is a fragmentary view in end elevation of a drum winder constructed in accordance with the principles 0f the present invention, with the winder drums and frame structure for the winder shown in phantom and 3,373,952 Patented Mar. 19, 1968 with other parts of the winder removed and shown in section;

FIGURE 5 is an end view of the Winder, showing the frame in phantom and showing one of the counterweights in section, in order to illustrate the support and control for the rider roll; and

FIGURE 6 is a sectional view line VI-VI of FIGURE 5.

In the embodiment of the invention illustrated in the drawings, I have shown in phantom in FIGURES l, 2, 5 and 6 a drum winder 10 including a base 11, shown in phantom, and parallel spaced posts 12, 12 shown in phantom as extending upwardly of opposite sides of said base. The base 11 carries bearing supports (not shown) for rotatably supporting a pair of spaced horizontally aligned Winder drums in a conventional manner. The base 11 may also form a support for a motor (not shown) and reduction gearing driven therefrom (not shown) for driving the winder drums 13, 13.

The posts 12, 12 each have parallel spaced facing channeled guides 15, 15 extending therealong (FIGURE 2) forming slidable guides for core shaft slides 16, 16 and rider roll slides 17, 17 disposed above said core shaft slides and slidably movable along said guides.

As shown in FIGURES 1 and 2, each core shaft slide 16 is in the general form of an elongated plate having a boss 18 extending outwardly of a central upwardly opening recess formed in said slide and forming a mounting for an eye bolt 19 having a flexible support and drive member, such as a drive chain 20 suitably connected to the eye thereof. The chain 20 forms a support for the slides 16 and is connected thereto in alignment with the center of the core shaft and roll of paper being wound thereon, and extends upwardly of said slide along a line disposed midway between the guides 15, 15 over an idler sprocket 21 suitably journalled in a cap 22 for the post 12, extending along the outside of said idler sprocket. The chain 20 extends from the top of the idler sprocket 21 about a sprocket 23 on the outer end of a control shaft 24 suitably journalled in the cap 22. From thence the chain extends downwardly to an eye bolt 25 mounted on a horizontal leg 26 of an angle iron, the vertical leg of which is bolted or otherwise secured to a fluid pressure operated cylinder 27, movable along a piston rod 29, fixed at its opposite ends. The piston rod 29 is mounted at its upper end in a flange 30 extending outwardly of the cap 22 for the post 12 and at its lower end in a shouldered portion 31 of the base 11. A second flexible drive device in the form of a drive chain 32 is connected to an eye bolt 33 mounted in the leg 26 of the angle iron and extends downwardly therefrom about a direction changing idler sprocket 35 and upwardly therefrom to an ear 36 extending laterally of the slide 16, and is suitably connected thereto to lower the slide 16 as the cylinder 27 moves upwardly along the piston rod 29.

The slide 16 is slidably guided along the channeled guides 15 on follower rollers 37, 37 engaging the insides of legs or flanges 38, 38 of the channeled guides 15, as

taken substantially along shown in FIGURE 2, the slides 16 also have parallel spaced vertically extending ribs 39, 39 spaced inwardly of opposite sides thereof and extending therealong. The ribs 39, 39 form abutments for retainer gibs 40, 40 extending vertically along said slides and secured thereto as by machine screws 41. The retainer gibs 40 have inwardly beveled engaging faces 42 slidably engaging corresponding faces extending along the ends of the legs 38 and retaining said slides 16 for vertical movement along the flanges 38, 38 of the channeled guides 15, 15.

The slide 16 has a rectangular boss 43 depending therefrom and extending inwardly therefrom and forming a mounting for a piston rod 44 extensible from and retractible within a cylinder 45. The cylinder 45 is shown in FIGURE 2 as being mounted on the outside of an outwardly extending boss portion 46 of the boss 43 as by machine screws 47. The piston rod 44 has a core shaft chuck 48 journalled on the outer end thereof and engaging within the end of a core shaft 49, a fragment of which is shown in FIGURE 2. The core shaft 49 may be of a conventional form and may be surrounded by a tubular shell on which the web is wound.

The leading end of the paper web is thus threaded around the tubular shell of the core shaft and suitably clamped thereto. The rolls 13, 13 are then driven to rotate the core shaft and shell so that a roll of paper will build up on said shell in contact with the winder drum 13, 13. As the roll builds up on the core shaft 49, the paper building up on said core shaft riding on the nips between the winder drums 13, 13 will lift the slides 16, 16 along the guides 15, 15 extending along opposite posts 12, 12, in cooperation with the cylinders 27, 27.

The core shaft chuck 48 and core shaft 49 mounted thereon are thus rotatable about coaxial axes midway between the guides 15, 15. The core shaft slides 16, 16 are also slidably supported equal distances from the center of the core shaft to provide a rigid slidable support for the slides and core shaft, with a resultant greater thrust capacity and a restriction in end play along the axis of the core shaft.

The cylinders 27, 27 at opposite ends of the winder may thus serve to quickly raise the core shaft slides and may also serve to lower the slides under the control of the control shaft 24. The control shaft 24 is suitably journalled in the caps 22 for the posts 12 at the top thereof and extends thereacross and is provided with a pair of parallel spaced flanges 50, 50 extending radially outwardly therefrom, having a brake 51 mounted in the space therebetween. The brake 51 may be a conventional diaphragm brake known to the trade as a Horton diaphragm brake, so only herein shown and described generally. The brake includes a lower shoe 51a lined with a brake lining (not shown) engageable with the periphery of the shaft 24. An upper shoe 52 is pivotally suspended from a bracket 53 on a pivot pin 54. The bracket 53 is shown as being suitably mounted on and extending inwardly of an associated cap 22 for a post 12. The shoe 52 has lugs 55 extending outwardly from opposite ends thereof. The shoe 51a has corresponding lugs 56 extending outwardly of opposite ends thereof. A separate rod 57 threaded at one end thereof extends through each lug 55 and the registering lug 56 and is secured to the associated lug 55 as by nuts 59 engaging opposite sides of said lug. A compression spring 60 encircles each rod 57 and is interposed between a collar 61 secured to said rod and the lug 56, to bias the brake shoe 51a in on off position. A fluid pressure operated diaphragm 63 is connected with the shoe 51a through a plunger 65, to apply the brake.

The brake 51 is interconnected in the fluid pressure circuit controlling operation of the fluid pressure operated cylinders 27, to apply the brake during raising movement of the slides 16, 16 and the core shaft 49 and thereby cont-r01 movement of the slides 16, 16 and make it possible to accurately stop the slides in a desired location. The brake may also control descent of the slides.

The rider roll slides 17, 17 are slidably guided in the guides 15, 15 and are vertically moved along said guides by flexible drive devices, such as drive chains 66, operated by fluid pressure cylinders 67, having piston rods 68 extensible therefrom, as will hereinafter more clearly appear as this specification proceeds.

As shown in FIGURES 1, 5, and 6 the slides 17, 17 provide supports for bearing boxes 69 at their lower ends, forming bearing supports for a rider roll 70, riding on top of the roll of paper during the winding operation and maintaining a predetermined pressure nip between the roll of paper and the winder drums 13, 13 and thereby exerting a predetermined force on the roll of paper as it is being wound, which decreases as the roll of paper builds up on the winder shaft and is relieved as the roll of paper 18 built up to a predetermined diameter. The bearing boxes 69 are held in place by bearing caps 94, retained to the bottoms of the slides 17 as by the machine screws 71.

One rider roll slide 17, shown in FIGURE 4 as being the left hand slide, forms a support for a motor 73 driving the rider roll through V-belt drives generally indicated by reference character 75. The motor 73 may be a speed reducer motor in which the speed of rotation of the rider roll may be varied in accordance with the diameter of the roll of paper. The drive to the rider roll is conventional and is no part of the present invention so need not herein be shown or described in detail.

As shown in FIGURE 5 each drive chain 66 is connected at one end with an eye bolt 76 extending through and secured to a lug 77 extending downwardly of the associated slide 17. From the eye bolt 76 the endless chain 66 extends upwardly over an idler sprocket 79, suitably journalled in the cap 22, to a control sprocket 80, suitably secured to the outer end of a control shaft 81 extending across the winder and tying the two chains 66, 66 on opposite sides of the machine together, to effect uniform raising and lowering movement of the rider roll. From the control sprocket 80, the chain 66 extends downwardly about an idler sprocket 83 on a shaft 85, mounted at its opposite ends in a clevis 86 on the top of the piston rod 68, and secured theretofFrom the idler sprocket 83 the endless chain extends upwardly to and is connected with an eye bolt 88, secured to a ledge 89, formed integrally with the post 12 adjacent the upper end thereof.

Extensible movement of the piston rod 68 will thus accommodate lowering movement of the rider roll 70 downwardly into engagement with the periphery of the roll of paper being wound on the core shaft 49.

The shaft 85 mounted in the clevis 86 is shown in FIG- URE 6 as extending beyond opposite ends of said clevis and forming a mounting for a counterweight 90 having a hollow central portion 91 opening to the inner side thereof and extending downwardly along the cylinder 67. As shown in FIGURE 5 the counterweight has an upwardly opening receptacle 92 contained therein, extending partially about the cylinder 67 and adapted to be loaded with the lead shot 93 or other weighting means, to provide the necessary weight to counterbalance the weight of the rider roll 70 and determine the pressure of engagement of the rider roll on the periphery of the roll of paper, in cooperation with the cylinder 67.

It may be seen from FIGURE 5 that the lead shot 93 may easily be inserted in the receptacle 91 or removed therefrom to the extent required to properly balance the rider roll 70. This overcomes the burdensome operation of adjusting the counterweight heretofore present in drum winders, and makes it possible to rapidly load the counterweight to the required weight for efficient winding requirements.

In operation, shot is loaded in the two counterweights to the extent required to initially adjust the counterweight so the system is in equilibrium with the rider roll just touching the roll of paper. Fluid pressure is released from the piston rod ends of the cylinders 67 and fluid pressure fnay be applied to the head ends of said cylinders in the amount required to provide a downward force of the rider roll against the roll of paper and create pressure nips between the roll of paper and the winding drums 13, 13. As the paper is wound on the core shaft, the diameter of the roll of paper will increase and the core shaft will move upwardly and raise the core shaft slides 17, 17 along the guides 15, 15. Pressure may then be released from the head ends of the cylinders 67 in the amount required to reduce the pressure of the rider roll on the roll of paper, until such time as the counterweights 91 take over to provide a minimum pressure of the rider roll on the roll of paper as the roll reaches its maximum diameter. Pressure may be relieved entirely from the roll of paper by applying fluid under pressure to the piston rod ends of the cylinders 67, 67 which may positively lift the rider roll 70 above the roll of paper. The control for the rider roll may be an automatic control of a conventional form and is no part of the present invention so need not herein be shown or described.

While I have herein shown and described one form in which the invention may be embodied, it may readily be understood that various variations and modifications in the invention may be attained without departing from the spirit and scope of the novel concepts thereof.
