7 Claims.

This invention relates to a winder that is especially adapted for winding a plurality of bands of web material into separate rolls.

For the purpose of disclosing one of the applications of the winder, it is shown in connection with a paper slitter that receives the full width web and cuts it into a plurality of bands.

When winding paper or other web material that is to be supercalendered, it is desirable that the paper be loosely wound but without wrinkles and the like that may cause a rupture in the paper during its travel through the supercalender stack. Heretofore, it has been the practice to rewind the paper from the paper machine upon a multiple drum winder, but this has proven unsatisfactory due to the fact that where the paper is to be supercalendered, it should be wound loosely, yet free from wrinkles or corrugations. When the paper is wound conventionally on the drum type winder, the supercalender must be driven at a relatively low speed.

The present improvements contemplate slitting the paper while winding it on a center wind type of winder, or a plurality of such winders. The paper after being slit and wound into rolls is ready for delivery to the supercalender stack. This procedure has proven highly advantageous in that it is considerably safer because wrinkles are avoided, and further it is possible to operate the supercalender at a great deal faster speed than heretofore has been deemed advisable.

The center wind type, or shaft winders in the present instance are preferably mounted at each side of a slitter one in front of the other and in such relation to the slitter that there is the same draw on each band of paper being wound. Provision is made to bodily displace one of the winding machines in an endwise direction after its roll has been unloaded in order to clear the way for the unloading of the other roll. The shaft winders are both mounted in upper portions of suitable supporting frames that are fulcru-med at their lower ends to permit the wound rolls to swing in an arcuate outward and downward path to be unloaded. The winding shafts are coupled to and are actuated by individual motors that are adapted to be uncoupled when the rolls are being unloaded. Also the bearings of each winding shaft are of a demountable character to permit the removal of the bearings and the shaft from the core of the roll after the latter has been unloaded.

It is one of the principal objects of this invention to simplify the construction of a winder for bands of web material such as contemplated herein, and to improve the efliciency, operation and dependability of such winder.

It is also a principal object of'this invention to provide a winder for bands of web material 2 that is adapted readily to unload the rolls from the winder device.

It is another object of this invention to provide a multiple center wind type of winder wherein a plurality of rolls of paper are wound thereon, one of the rolls being first unloaded and the winder then displaced to permit the removal or unloading of a roll on another Winder back of the first winder.

A further object of this invention resides in providing a machine for winding a plurality of paper rolls and maintain the same draw on each of the bands being wound.

It is also an object hereof to provide a winder for bands of web material that are received direct from a slitter, and to maintain identical draw upon the several bands during the winding thereof.

Additional objects, aims and advantages of the present invention will be apparent to persons skilled in the art after the construction and operation of the present winder is understood from the within description. It is preferred to accomplish the numerous objects hereof and to practice the invention in substantially the manner hereinafter fully described'and more particularly pointed out in the claims. Reference is now made to the accompanyin drawings.

In the drawings:

Figure 4 is an end elevation looking at the left hand side of the structure shown in Figure 1 and drawn to an enlarged scale;

Figure 5 is an axial section showing details of a Winder shaft, and parts immediately associated therewith.

The drawings are to be understood as being more or less of a schematic character for the purpose of disclosing a typical or preferred form of the improvements contemplated herein, and in these drawings like reference characters identify the same parts in the different views.

A roll of sheet material such as paper and the like may be placed upon an unwinding stand (not shown) that is equipped with a suitable braking device, and the paper web is fed therefrom to a slitter structure that comprises a top or table 5 supported upon legs 6 and having a plurality of rollers I journalled in bearings 8 that are mounted upon the table 5. One of the bearings 8 is provided with upstanding arms 9 3 for journalling the spindle of the slitter ID that comprises a disk having a knife edge opposing the adjacent roller 'L- The other two rollers! at both sides of the disk respectively receive the paper web from the unwinding stand, and

then deliver the slit bands to the winder ma chine that comprises two assemblies that are located one below the table or platform and the other in front of the stand in the manner shown in Figure 4.

These winder assemblies, designated generally as A and B, are respectively fixed and mobile. In other words, the winder assembly A is mounted on a stationary support within the table or stand, while the mobile winder assem bly B, is of a movable" character and in normally operating position has a portion laterally overlapping the fixed assembly A. The mobile assembly B is adaptedtobe' shifted endwlse from in front of the slitter and the other winder after its" roll has been unloaded to provide space to accommodate unloading of the stationary assembly A. It will be noted that the slitter is located so that it gives the same or approximately the same length of draw on the bands going to the winders. The winders are at a lower level than the slitter and are laterallyoifset with respect to each other, with portions of one overlapping laterally portions of the other. Each of'the winders, as will be later explained has its own individual drive so arranged as to maintain constant tension on the webs as they are being simultaneously wound into the separate rolls on the winder assemblies A and B.

The details of the winder assembly A are shown in Figure 3, and the shaft, bearings and other details thereof are shown in enlarged longitudina'l section in Figure 5. This assembly comprises elongated I-beams H, H disposed in laterally spaced parallel relation to each other and at one end thereof there is a block I2 having a saddle l3 on its top" for receiving and mounting an electric motor H. The motor shaft l5 has a pinion l6 anchored to it for drivingthe gear I! on the ad acent end of the driven shaft I8. This shaft has its end adjacent the gear l'l ,iournalled in an elongat d bearing 19 at the u per end of a pedestal 20a ar sing from the base rails H. The other end of the shaft 18 receives a sli able co p n sleeve 20 that is rotatahle with t e shaft I8 by rea on of a key and kevwav connect on 2| t erewith. A latch bar 22 in a recess on s aft i8 maintains the sleeve a ainst lon itudinal movement toward the beariri I! bv the enga ement of t e end of bar 22 with t e a'diacent end face of t e sleeve 20. A p n 23 fulcrums an e d of the latch bar in its re and a shrine 2A se ted beneath it urges themnva le end of t latch bar upward or outwa d radial to the s aft.

The structure that supports the roll being woun'd' has operative connect on with and is rotated by the s aft 18 throu h the medium of the col ar 2n. Thiswindin structure comprises a; ion tubular winding shaft 25 t at carries the core M for the pa er roll. The end of the metal tube 25 nearest t e motor end of the winder has the reduced end of a hub 21 inserted into it and secured thereto in any suitable manner preferably by a press fit. The other end of this hub-21 opposes but does' not contact the adjacent end of the shaft l8 and it is provided with a longitudinal keyway 28 to receive the key of the keyway connection 2! between the collar and the shaft. Between the keyway and the outer end of the tube, the hub is received in suitable antifriction bearings 29 carried in a cupped housing" ,surrounding the: bearing; anfd the hub. The open end of' housing"!!! is closed by a removable cap 3|.

The bearing housing 30 has an annular recess 32 circumferentially of its cylindrical portion to fit it into a concave seat 33 in a boss at the upper en'd of -rocker arm 34. A pivoted concave clamp yoke 35 engages around the upper portionof'thebearing' housing 30 and is fulcrumed at itsalower end-of a pin 36 (Figure 2). Opposing lugs 36a are formed on adjacent portions of the boss and the clamp yoke opposite the pin 36, and a hand operated clamping screw 31 engaging these lugs is adapted to draw" the parts together for clamping the bearing housing 30 in the seat at the upper end of the'arm 34.

The lower end of the arm 34' is provided with a slit boss 3!! the parts of which are drawn togetherby bolts 39% engaged innlugs 38a to clamp the arm 34 rigidlyto a rocker shaft lillocated in a horizontal plane adjacent the rails I I of the base. The'rockershaftlfl has reduced end portions 41 and: 42: that arereceiv'ed in bearing a housings 4'3 and respectively; Antifriction bearings 45 and 46' are interposed between the ends of the rocker shaft Miand' the respective bearing housings l3- and" '44", and the bearing housings have open ends that are closed by removable plates w'and 4 1 respectively, which are held in place by boltsorthelik'e (Fig. 3-)

The end o'f-- the' metai tube 25 (Figure 5) that is remote to the coupling sleeve 20 receives a shouldered hub- 48,-the'adjacent reduced portion of which is entered in said tubeandis secured thereto in any suitable manner, preferably by a press fit. A bell-shaped sleeve 9' is loosely fitted upon the hub beyond the metal tube 25 and is arranged to have itsend portion abutting the roll-core 26. The flaired' out portion of this sleeve is of greater diameter than the hub 5-8 and is provided with internal threads W while the exterior portion is ofangular form to receive a wrench. This sleeve limits" longitudinal movement of the core upon the'tube 25; Another sleeve 5|, loosely mountedon the hub has a threaded outer portion that is screwed into the first sleeve 49 and it has an angular flange to receive awrench. The outer end of sleeve 5| has a recessed face 53 and the adjacent portion of the hub is provided 'with an annular channel 54 to receive a two-par-t ston ring, that forms an abutment on the'hubz The proximate or opposing ends of the ring segments are shouldered as indicated at SBirr'FiguresB and 5. The seating of this ring or stop 5 in channel 54- prevents said' stop-moving longitudinally on the hub 48. By applying wrenches the angular portions of the sleeves 48 and 5-! they may be rotated with respect to each other to press the sleeve 5| against the stop ring 55 and the opposite end of the sleeve 49' against ion dose 26, thus frictional'ly locking these partstdgether.

Beyond the stop' riiigji the hub 48, is reduced to provide a shoulder 51 and anannular bushing 58 surrounds the adjacent portion of the hub with its inner end portion eriliged with the shoulder 51. An open ended sldt I! isma'de in bushing 58 that cooperates with a; lateral pin 60' projecting from the hub to spline and bushing together for rotation seen other and also to permit the bushing to be removed longitudinally endwise from the hub. Antliriction bearings 60 are interposedbetwoenthe bushing II and a cupped bearing housing 6| that has its open end closed by a removable plate 62. The cylindrical face of housing 6| has an annular channel 63 to receive the opposing members of a separable clamp device 63a carried at the upper end of a rocker arm 64, said clamp device being similar to the clamp at the other end of the winding tube.

- The parts of this clamp device 63 are drawn together by a hand operated screw member 65 that engages opposing ears 66 on the respective members of the clamp. The movable or swinging member of this clamp device is fulcrumed on a pin 61 to allow the clamp to be opened and swung downward when unloading the roll from the mounting frame. The lower end of the swinging arm 64 is provided with a two-part boss 68 surrounding the adjacent portion of the rocker shaft 40, the parts of this boss being drawn together around the shaft by clamping bolts 69 engaged in spaced ears 68a, in the same manner as the other swinging arm 34 is secured to the opposite end portion of the rocker shaft Ml. A spring projected latch bar 22a, operating in a recess in the outer portion of hub 48, prevents longitudinal movement of the bushing and housing on the hub when the clamping device has been released and the roll unloaded.

Between its end bearing housing 44 and the boss 68 the rocker shaft All has a collar ll! secured to it and there is an arm H projecting from this collar having at its outer end a segmental rack 12, the teeth of which are meshed with a pinion '53 carried upon the outer end of a spindle 14 projecting from its bearing on a gear housing 15 rigidly mounted on the bearing housing 44. A large worm wheel 16 (Figure 4) is secured to shaft 14 inside the housing With its teeth meshed with a worm H on a rotatable operating shaft I8. An end of this shaft projects out of the housing where it is provided with a crank 79 for rotating it preferably by hand.

After the roll has been wound on the tube and core of the winder assembly which has been described, the motor M is stopped and the clamps 35 and 53 are opened. The motor is then uncoupled from the hub 2'! by depressing latch bar 22 and sliding the sleeve towards the drive shaft bearing l9 until the sleeve has cleared the previously engaged portion of hub 27. A wheeled truck or dolly 8!] is placed in front of the roll supporting devices and the crank 19 is then rotated to operate the gearing which in turn moves the rack 72 to swing the arm H thereof outwardly towardthe truck or dolly. This operation Will rotate the rocker shaft MI in a direction to move the roll supporting rocker arms 35 and 64 downward until the roll is resting on the dolly 30. After the roll has been deposited upon the truck or dolly the bearing housings 30 and 6! are removed endwise from the respective hubs 21 and 48. The core retaining sleeves 49 and 5| may then be rotated in a direction to release the tension or pressure between the core 26 and the stop or collar 55, whereupon the collar may be separated and the sleeves 49 and 5! may be slipped endwise from the housing. The structure is then reassembled by telescoping another core 26 upon the tubular shaft and tightening it in place by means of the sleeves 49 and 5%. The bearing housings 30 and Eli are then replaced and the crank rotated to operate the gearing and rock the shaft in a direction to restore the tubular shaft 25 to its operating position in axial alinement with the driven shaft I8 to which it may then be coupled by sliding the collar 20 away from the bearing I9 6 to engage the key in the keyway 28 of the hub 21.

The foregoing description has been directed to the winder assembly designated as A. The winding assembly which is designated as B is identical with that described in connection with the assembly A with the exception that its components are arranged in opposite order with portions of the two winders overlapping each other in a lateral direction. For the purpose of simplicity, the same reference characters have been applied to corresponding portions of the assembly B as hereinbefore described with respect to the other assembly A.

Both motors M of the two assemblies A and B are constant horsepower motors and therefore maintain constant and equal tension in the separate draws I00 and I0! (Fig. 4) of the webs as they are being wound on the rolls C and D. As is obvious, more than two rolls could be simultaneously wound by merely adding other assemblies like assembly B.

In addition to being of the same construction as the assembly A, the assembly B is of a mobile type that is adapted to be moved endwise away from the slitter device after the assembly B has unloaded its roll. The assembly B is mounted upon longitudinally disposed I-beam rails I la, I la that rest on tracks 82, 82 embedded in the floor in front of the table. These tracks have oppositely projecting flanges 83 that are engaged by the inturned flanges 84 on the bottom of the rails Ha. An elongated screw or worm shaft 85 has threaded engagement with a nut 85a or other threaded element anchored to a suitable portion of the winder assembly B as shown in Figure 2. This screw shaft has its other end journalled in bearings 85 of a housing 81 that is in spaced relation to or removed a distance from the adjacent end of theassembly B. The spindle 88 of an electric motor 89 enters the housing 86 and has a suitable gear connection with the worm shaft 85 to rotate it.

In normal or winding position the winder assembly B is shown in full lines in Figures 1 and 2. After the roll has been unloaded from this winder assembly, the motor 89 is started and the entire assembly B is slid endwise to the position shown in dotted lines in Figure 1. This will displace it from overlapping relation to assembly A and will clear the space in front of the slitter table. A truck or dolly may then be moved into the proper position in front of the roll on the winder assembly A so that the roll may be unloaded onto said truck in the same manner as the other roll was unloaded from the assembly B.

The tubes 26 or winder shafts are long enough for the maximum width of any single roll that they may receive from the slitter. As will be seen in Figure l the dotted lines C and D on the respective winder assemblies indicate the respective rolls of paper that have been wound thereon and it will be noted that these rolls are oifset with relation to each other, and the adjoining edges of the slit webs lie in substantially the same vertical plane. By referring to Figure 4 it will be noted that the slitter is so located with respect to the winders A and B as to give the same amount of draw to each of the webs being wound. The winders are disposed on each side of the axis of the slitter although the respective rolls C and D are offset with relation to each other. The motors It for driving the winder assemblies are preferably in series circuit which operate them in unison and synchronized with respect to each other so that the paper rolls are of uniform size and proportion.

It: will, of course, be understood that various details: of construction may be. varied through. a wide range withoutideparting'fizom the principles of this invention anditis; therefore, nott-hepurpose to limitthepatentgranted hereon otherwise than necessitated; by the. scope: Of the appended claims.
