To aZZ whom it may concern.-
Be it known that I, ANTON SKOFSRUD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Paper-Reeling Machines, of which the following is a specification.
This invention relates to mechanism for antomatically forming sheets of paper into rolls, tubes, or rigid cylinders; and it consists in combining With means for feeding a continuous sheet of paper a lengthwise-reciprocating tubular spindle having lateral suctionperforations, means for causing suction therein while it is stopped over the path of said sheet to pick up the edge thereof, and means for concurrently actuating the feeding mechanism and rotating said spindle; in combining with said apparatus means for applying paste to the surface of the sheet asit is wound upon the spindle; in combining with said apparatus'paste-applyin g mechanism acting momentarily immediately after the edge of the sheet is picked up and again as the roll approaches completion, and shearing mechanism acting immediately preceding the final action of the paste-applying mechanism; in improved means for regulating the speed of the feeding mechanism in accordance with the size of the roll, and in various other features and details of construction hereinafter described and claimed.
In the drawings, Figure 1 is an elevation of apparatus embodying my-iuvention viewed from the reeling end of the machine. Fig. 2 is a longitudinal elevation with parts omitted from the front side of the machine, showing, among other things, the double cam-drum for projecting, staying, and retracting the suction-spindle and the clutching mechanism for engaging the paper-feeding and spindle-rotating devices with the main driving-shaft-. Fig. 3 is an enlarged fractional elevation of reeling part of the machine, showing paper feed and cutting knife; Fig. 4, an enlarged transverse section on the line at 4 of Fig. 2, seen in the direction of the arrows; Fig. 5, an enlarged plan View of thedouble cam-drum detached ,showing the gate and switches therein; Fig. 6, a transverse section through said drum on the line 6 0 of Fig. 5; Figs. 7, 8, and 9, enlarged details of the gates and switches appertaining to said drum; Fig. 10, a fractional longitudinal section through the vacuum-cylinder and valve-piston therein, showing also a portion of the suction-spindle; Fig. 11, an enlarged detail, partly in transverse section, of the double cam-drum, the traveler operated thereby, and the vacuum-cylinder carried by said traveler; Fig. 12, a detail of the clutch-shipping lever and its engaging catch, and Fig. 13 a sectional detail showing clutch and pulley at the junction of the sections of the main shaft.
A designates a strong rectangular benchframe mounted upon suitable legs A, with transverse bars A tying said legs therebeheath and serving as supports for various bearings mentioned in the ensuing description. For convenience in identification the location and direction of movement of groups and elements of the apparatus will hereinafte'r be defined as right or left or front or rear with reference to the position of this frame, as indicated in Fig. 2 of the drawings.
13 is a main driving-shaft in two sections 1" and 2 running longitudinally of the frame and turning in bearings b, secured to the aforesaid tie-bars, and B is a driving-pulley fixed to the left-hand section of said shaft and constantly driven from any suitable source. Rigidly aflixed to the right-hand section of shaft B, at the point where it abuts against the rear section, is'a second pulley B connected by belt I) with a smaller overhead pulley B which is suitably pinned, as by screw B to elongated bushing B, resting and revolving in bearings b supported by brackets B from the bench and stayed against endwise movement by annular end flanges b snagged against the outer faces of said bearings.
C is the vacuum-cylinder, sliding lengthwise through said bushing B and turned therewith and thereby through engagement of its longitudinal spline c with groove 0, cut lengthwise of the bushing. At its rear end the cylinder is fixedly held in clamping-bushmg C, journaled in bearing C upon the traveler C which reciprocates lengthwise of the bench in ways 0 to a distance advisably somewhat exceeding the width of the sheet to be reeled. The right-hand end of the cylinder is stopped by a plug 0 into which is axially tapped the suction-spindle 0 having lateral perforations c and closed at its farther end. The plug is adapted, as by keysockets c", to be readily removed and re placed by others carrying spindles of different diameters, according to the nature of the work. i
In the vacuum-cylinder is a piston D, secured to a rod D of such length that when the cylinder is at the extreme left-hand limit of its reciprocation the valve is closely adjacent to the aforesaid plug and which extends through the open rear or left-hand end of said cylinder and through a bearing d on the frame and at'its extreme free end is screwthreaded to receive adjusting and jam nuts d, which confine an encircling coiled expansion-spring D against said bearing, whereby the piston-rod is normally retracted to the full limit permitted by a collar d pinned thereto on the other side of the bearin g. With this arrangement it is evident that since the piston is held back yieldingly against accompanying the cylinder in its advancing movement by its spring-seated rod a vacuum will be formed in said cylinder during each traverse to the right, creating a strong suction through the perforations of the spindle, and that the drag of the vacuum uponthe piston itself will overcome the resistance of the spring D to such an extent thatthe piston will be carried along some distance in the same direction with the cylinder until the longitudinal movement of the latter stops at the extreme of the traverse to give space for the rotary or winding movement, when the expansion of the spring will retract the piston, and thus continue the lateral suction through the spindle for an appreciable time, so that it may pick up the edge of the sheet fed above it.
During the advancing movement of the vacuum-cylinder and until the suction-spindle closely approximates its winding position the pulley B is disconnected from the rear orleft-hand section of the main drivingshaft, so that vacuum-cylinder and suction-spindle are unaffected by the revolution of the latter; but as the traveler O nears the limit of its forward traverse it' strikes and moves the upper end of clutch-shifter lever E, and thereby causes the engagement of sliding clutch E upon said rear section, which advisably is a conical friction-clutch, as shown, with said pulley, and locks the sections together, when the pulley instantly by means of belt b communicates motion to overhead pulley B and rotates cylinder and spindle at a greatly-multiplied speed over that of the main shaft' The instant the reverse traverse of the cylinder commences, which will be after a suitable interval to permit the winding of a roll of the desired size, the pulley B must be disengaged from=the driving-section of the main shaft to stop the rotation of the spindle, and lest the usual spring employed for such pur pose in similar locations should not act promptly enough to break the contact be tween the friction clutch-faces I preferably make the unclutching positive by means of a spring-catch E on the forward face of the traveler-block beveled advancingly at e to ride over the shifter-lever in the right-hand traverse, but shouldered in rear, as at e, to drop over and hold said lever in the left-hand traverse and carry therewith until the clutch is disengaged and the lever so inclined as to release said catch. WVhen the suction-spindle reaches the end of its forward movement and begins to revolve, it is just in advance of and practically in flush contact with the adjacent knife-edge of the self-adjusting table F, arranged transversely to the length of the bench-frame at the right-hand end thereof and over which the sheet to be wound is fed. This table is supported by pins f in convergent guide-slots f at the top of standards F, which rise from an extension-bracket F bolted to the front of the bench-frame, and it is normally checked in a horizontal or inclined position, depending upon the diameter of the suction-spindle used, by an adj ustable stop f which stays the knife-edge at the level of the upper surface of said spindle. The stop offers no resistance to any upward movement of the knife-edgc. Therefore as the papersheet is wound upon the spindle and the diameter of the roll increases the knifeedge resting thereon gradually rises and the table tips in its guide-slots to direct the sheet constantly to the top of the roll.
' The sheet is fed to the table and over it to the spindle by rollers G and G, the first of which is driven and the other simply a pressure roll turning in yielding bearings g, pressed down by spring g toward said driven roll. The feed-roll G is driven and its speed is automatically increased as demanded by the increasing diameter of the paper-roll being wound in the following manner, to wit: Alongside pulley B on elongated bushing B is keyed a second pulley H, which when the bushing, and consequently the spindle, is revolved drives back by belt h to pulley H, fixed to the rear or left-hand end of countershaft H hereinafter termed the feedshaft. Upon the right-hand end of this feedshaft is keyed a friction-disk h, which engages with a friction-wheel 7L2 upon the lower end of a vertical shaft H turning in long sleeve-bearing h and hearing at its upper end a second friction-wheel h", which in turn engages with a friction-disk 72, on the extended gudgeon h of the feed-roller. The
friction-wheel it engages with its drivingdisk above the axis of the feed-shaft, and the friction-wheel 77, engages with the disk which it drives below the axis of the gudgeon of the feed-roll. Therefore an ascending movement of their vertical carrying-shaft, hereinafter termed the change-speed shaft, will result' in lengthening the driving-surface in contact with one for a single revolution of the feed-shaft and contracting the surface which the latter must travel over to produce a single revolution of the feed-roll, thus speeding the latter, while a descending movement, on the contrary, will slow down the feed-roller. To regulate this change of speed, the friction-Wheels may each be adjustable on its shaft by means of binding-screws 72 set in their hubs, as shown. To impart the rising movement to the vertical shaft, its lower end is stepped upon the subtending arm 7: of a lever K, pivoted to the frame, and by its opposite arm supporting a sliding bar K in contact with the surface of the increasing paper-roll, so that with each additional convolution added thereto the arm 76 is depressed and the arm 7t correspondingly raised, lifting shaft H and its friction-wheels and accelerating the feed-roll. When the reeling is completed and the suction-spindle withdrawn, stripping off the paper-roll, the vertical change-speed shaft will fall by its own weight to normal slow-feed position and the lever K will be restored to starting position, where it will be stayed by contact with lug 7& before the upper or contact end of sliding bar K has risen where it will obstruct the ensuing advance of the suction-spindle, but Will come in contact with the paper wound thereon as soon as any appreciable demand is made upon the feed.
Above and parallel with the suction-spindle when in its extreme advanced position is a smoothing and compacting roll L, mounted in hearings in the lower ends of sliding bars L, which work in vertical ways Z in the overhanging brackets L upstanding from the rear of the bench-frame. These bars are extended with rods 1, screw-threaded at'their ends to receive adj usting-nuts Z whereby the limit of their downward play is determined,
' and encircled by coiled springs Z which press the smoothing-roll into constant contact with the paper-roll as the latter is wound. As said paper-roll increases in diameter With theprogress of the reeling the smoothing-roll, the object of which is to lay the convolutions uniformly and compactly together, is lifted, with its carrying-bars, against the force of the springs Z until finally, with the completion of the reeling friction-dogs L on a rockshaft Z engaging with each sliding bar, lock the roll against descent while the suctionspindle is being retracted and until it is again advanced and begins reeling. Then the cam m on the right-hand or intermittent section of the main shaft acts against the lower end ofa rod M, guided in vertical sleeve m, and
at its upper end connected to a crank m from the dogging-shaft Z, and lifts it, rocking said shaft and disengaging the dogs, when the smoothing-roll is immediately carried down toward and into contact with the accumulating paper-roll.
To sever the sheet when a roll of suitable size has been reeled-on the suction-spindle, a knife or shear blade 02 is secured to the inner face of a block N, pinned to guide-rods N,
which play in cars n,proj ectin g inwardly from the aforementioned extension-bracket F and also through a ledger-plate n, over which the sheet is advanced by the feed devices and against which it is severed on the descent of the knife. The knife-block N is normally held elevated bysprings N but immediately before the rotation of the suction-spindle ceases a cam or tappet P on the intermittent section of the main shaft B strikes the pendent arm 13 of an elbow-lever P, pivoted atp to a standard P from the bench-frame and forces down the overhanging arm 19 of said lever, which normally rests in contact with said block, carrying the block down and cansin g the knife thereon to shear past the ledgerplate. This action takes place sufliciently in advance of the cessation of rotation of the spindle to permit the reeling in of all that part of the sheet extending along the table between spindle and shearing mechanism.
One of the purposes for which this machine is designed is to form tubes for firework use. This requires that both the initial and the final edge of the paper-roll shall be pasted, and to that end a paste-trough R is located beneath the bench-frame to contain a supply roll R, having its gndgeons seated in open bearings r in the ends of said box and pivoted in the lower end of frame-bars R which at their upper ends, on the rear side of the advanced position of the suction spindle, carry a roller r, adapted to be swung into contact with said spindle or the paper-roll thereon. Over this roll 0" and around a. lower roll r mounted by its gndgeons in longitudinal slots r in said frame-bars and adapted to bear by gravity against the supply-roll, is led an endless paste-apron R which is moved each time it comes in contact with the revolving paper-roll, and thereby moves the supplyroll. Normally the apron is kept away from the paper-roll by expansion-springs r seated against bent retraction-arms S, pivoted to said frame-bars and pressing outward against the heads of dowel-pins 5, playing through said arms and connected to the bars; but immediately after the new edge of the sheet is picked up by the suction-spindle the lower arms of bent levers S are struck by tappets s on the intermittent section of the main shaft and the upper arms thereof are carried forward to strike the paste-frame bars and force them toward the spindle against the resistance of said springs r causing paste to be applied to the paper edge, the paste-frame being immediately retracted by the springs as the tappets pass off of the lever-arms. As the paper-roll increases in size some provision is necessary to keep the paste-apron at a suitable distance therefrom that paste may neither be applied where it is not wanted nor the operating devices changed in their rela, tions. To this end the upper extremities of the bent retraction-arms are provided with antifrictiona-olls .9 which rest on inclined tracks 5 cut in the sliding bars L of the 'the lifting of said roll by the increase in size of the paper-roll said retraction-bars shall be forced out, carrying the paste-frame with them, away from the spindle. When the knife has been actuated and the reeling of the paper approaches its completion, a second set of tappets s on said intermittent section of the main shaft strike the bent levers S and again force the paste-frame inward that the apron may touch and prepare the roll for the pasting down of the terminal edge by the pressure of the smoothing-roll. Nuts .95 on the dowel-pins enable the stress of springs r to be adjusted so that the normal distance of the paste-frame may be determined nearer to or farther from the suctionspindle, and the tappets s and 8 may be set by means of screws 3 passing through their hubs to advance or retard or omit altogether one or both of the pasting movements. The paste -frame, with its attached retractionarms, being unconnected, except by contact with the paste-trough and with the inclined tracks 8 may be lifted bodily out of the machine in case it is intended to merely reel and not to paste the paper sheet. The suctionspindle in its advancing movement passes through and is guided by a bearing S located at the left-hand side of the passageway for the paper sheet, so that in reeling the adjacent end of the paper-roll is practically in contact with the right-hand side of said bearing. Therefore when the series of operations, heretofore described, terminating with the final severing and pasting of the sheet are finished and the suction-spindle begins its retreating traverse, followed immediately by the cessation of rotary movement, the paper-roll is stopped by this bearing and stripped from the spindle to drop through the open bench-frame into any suitable receptacle .placed beneath.
It is evident that the movements and effective engagements of the various elements of the machine may be primarilyinduced and controlled in a great number of ways from the main shaft; but that which I have specially devised and prefer to use for the pur pose consists in a reversely-cam-grooved drum T, Figs. 2 and 5, keyed to the rear or lefthand section of the main shaft, and by the revolution of which the traveler is alternately carried to the right from its rearmost position (indicated in Fig. 2) until it has engaged and operated the clutch-shifter, held stationary while the suction-spindle is being rotated, and finally withdrawn to its starting position to immediately resume its forward traverse. For the purpose of describing this drum and its mode of operation it will be conventionally assumed that the View thereof in Fig. 2 is a side elevation, and Fig. 5 a top plan. Then at the outset the pendent roller T engages with the longitudinally-trending cam-grooves T and T of said drum at the neutral point 00, Fig. 5, and in the advancing"- movement, with the drum rotated as indicated by the arrow, it follows the groove T and is in thrusting contact with the rear edge if thereof, ultimately returning by the groove T and in contact with the front edge 25 of said groove. The two grooves are described around the drum on opposite spirals, merging into each other with a slow or rounded sweep at the starting-point, crossing each other centrally beneath the drum, and meeting again on top at the return-point X in an angle which opens into a circumferential groove T", which is traversed by the rollerT during an entire revolution of said drum before entering the return-groove,whereby the traveler is held stationary during the reeling operation.
In order that the traveler-roll may not take the wrong groove at the point where the grooves cross each other, each groove is provided upon its contact edge t and 1., respectively, with a spring-held hinged gate 25 and t normally closing the entrance to the crossing and adapted when opened to make the contact edge of its respective groove continuous thereacross. This gate is struck by the traveler-roll in its approach to the crossing and pushed open to afford a bridge for its passage. Afterhaving left the gate in the advancing groove T the traveler roll approaches the return-angle, and here it is requisite that its entrance into return-groove T should be temporarily barred, so that it may with certainty engage with'the delay-groove T and travel therearound its allotted period. To this end just before reaching said point it strikes and rides upon a yielding cam-block T closing the groove T depressing it, and thereby rocking a lever t on fulcrum t and raising a guard-block T to close the entrance to the return-groove. Simultaneously with the depression of cam-block T and elevation of guard-block T a cam-block T is raised in the delay-groove T in advance of the returnpoint, and a switch-block T connected therewith by lever t, fnlcrumed at and until then closing the entrance to the delay-groove, is retracted, opening a clear passage for the roller. This simultaneous action of the guard and switch blocks and their cams is induced by intercommnnicating lever i and when once thrown the parts are maintained inposition until again actuated by the travelerroll by the frictional contact of spring-washers t on their lever-fulcrums or other suitable means. The traveler-roll having entered the annular delay-groove journeys therearound until it strikes and depresses cam-block T near the return-point, thus throwing up the switch -block T and retracting the guardblock T closing the delay-groove to further advance and opening a track into the returngroove, which it follows to gate i and, bridging the crossing therewith, continues back to the starting-point, when it immediately commences a fresh advance, of course carrying with it the traveler and its attachments in all these movements.
