62 Claims.

This invention relates to improvements in web rewinding machines.

The invention has many important objects including the provision of means for assuring accurate registry of the cores with the web portions to be wound thereon; the provision of means for slitting the cores upon the sam machine in which the web is slit and the rewinding is accomplished, whereby the cores, instead of being threaded on to the winding core shaft, are slit directly on such shaft and immediately thereafter receive the correspondingly slit portions of the web in the winding operation; the provision of means whereby a controlled, fanlike spray of water is delivered from below on to the web, which is tensioned across the empty cores, for severing the web and causing its severed end to adhere to the cores; the provision of an alternatively available means for mechanically severing the relatively waterproof web, such as wax paper, and concurrently causing its cut end to be delivered to the empty cores upon which the web is to be wound in the next operation; the provision of means whereby a single manual operation removes a full core shaft from the machine and substitutes a new core shaft with empty cores freshly cut and accurately positioned thereon; the provision of a novel and improved means for assuring a driving connection from the core shaft to the cores during the winding operation; and the provision of novel and improved means for carrying out the above described functions to enable the machine to be operated simply, effectively and with improved speed as compared with any previously known device for the purpose, while nevertheless adapting it for operation by unskilled operators.

Other objects will be apparent to those skilled in the art upon study of the following disclosure of the invention.

Figure 15 is a view principally in front elevation but partially in section fragmentarily illustrating portions of the mRhine equipped with the modified apparatus shown in Figures 13 and 14.

Like parts are identified by the same reference characters throughout the several views.

While the machine as herein disclosed may be used fOr many rewindin functions, it has particular utility for winding toilet paper or other tissue upon cores for distribution and use and, as modified by inclusion of the alternative web cutting mechanism shown in Figures 13 to 15, the machine is particularly useful in winding wax papers and the like upon cores for distribution and use.

That portion of the apparatus which precedes the actual rewinding operation is generally con- Mounted directly upon shaft 16, as best shown in Figure 1 (assuming the machine is used as a toilet rewinder or for the rewinding of towels or tissues), is a matrix roll 21 with which the knives of the perforator roll 28 coact to perforate the web.

The web is drawn from a parent roll 29, passes over the felt covered roll 30, and about the matrix roll 21, and between the matrix roll 21 and the felt covered roll 3|, and thence over the slitting matrix roll 32 where it is acted upon by the slitting knives 33 carried by shaft 34. The shaft 34, as well as the shafts carrying the several rolls 3U, 28, 3| and 32 are all mechanically driven by the gearing shown at the right in Figure -2 which, however, need not be described in detail here. It will, of course, be understood that any desired number of the disklike slitting knives 33 may be located at any desired spacingupon shaft 34 to divide the total width of the web into such appropriate lesser widths as are adapted for the particular purposes of the machine.

The present invention is more particularly concerned with the portions of the apparatus now to be described.

Portions of the opposite sides of the frame I! are provided with projecting shoulders defining a path of movement of the ends of the successive core shafts. For convenience, these path-defining shoulders may be considered as separate guideway sections. While Figure 1 shows the inside surface of only one of the sides of the machine frame, it will be understood that the pathdefining shoulders are similarly arranged at the opposite side of the frame. 7

There is a shoulder comprising a first guideway at 40 into which the operator may introduce the core shaft with a single unslit length of core tube extending from end to end thereof. The guideway 40 is inclined rearwardly from the operators station at the front of the machine so that the core shaft is fed by gravity to the slitting station A at which the empty core shaft is indicated at 4| in Figure 1.

From this station, a second guideway section 42 leads downwardly at so sharp an angle as to be almost vertical. At the bottom of guideway section, 42 is the second station B at which the core shaft with individual cores separated by a slitting operation rests in the position indicated.

From this position, a third guideway 44 leads forwardly, terminating at a third station C in a pocket from which the full core shaft with its load of fully wound rolls may be removed by hand. As will hereinafter be explained in more 1 detail, the tubular core material is peripherally slit todivide it 'into separate'cores at station A. The winding is done at station B. The core shaft :is engagedin chucks. and driven at both of these stations. The core shaft, carrying its burden of wound paper rolls, is delivered, while still -chucked, from station B to station and there released from the chucks while concurrently a.

core shaft bearing empty cores is dropped from station A to station B and is there engaged by the; empty chucks following their return to station B from station C. I shall first describe the .core shaft and then describe the mechanism which cooperates therewith at each of the successive stations.

' The core shaft generically designated erence character 4| is speciflcallyillustrated in Figures 7 to 9. It comprises a tube 45 to the ends of which are fitted the plugs 45 and 41.

the former being squared at 48 and the latter being tapered at 49 to engage the respective chucking means. The tube is provided at spaced intervals with hardened bands, preferably made of steel and welded thereon as indicated at 50. These bands are so'located as to cooperate with the core cutting disks.

Between the bands 50. the tube 45 is pierced with holes 5| opening in various directions through its periphery. Within the tube is a sack 52 of rubber or other similar material which may be dilated with air pressure to expand outwardly through the holes 5| into pressure engagement with a core 53 sleeved on to the outside of the core shaft as indicated in Figures 7 and 9. At its end the sack 52 is connected to a nipple 54 threaded into the core shaftplug member 41 and communicating with a duct 55 through which air pressure may be communicated from a special chuck shown in Figure 7 to the interior of the sack. This special chuck is used during the winding operation and, therefore, will not be described until later.

At the top of the frafne is the core slitting mechanism comprising sets of coacting knife disks 50, 6i and 62, all of which are mounted for rotation. The arms 63 which mount the disks do not move during the operation of the machine, being carried by a fixed shaft 64.

The disks SI and 52 are respectively carried by arms 650 and ll from rock shafts 65 and 66, these being intergeared for simultaneous oscillation by segments 61 and 68 (Fig. 4 and Fig. 2) which are at the right of the machine as viewed from the operator's station at the front thereof in Figure 2.

All three-of the knife disks which comprise a given set are in the same plane to cutupon the same line peripherally of 'the core'sleeve on v the core shaft. The number of sets of knives respective shafts.

At the left of the machine, as viewed in Figure 2 and Figure 3, the shaft 65 is extended and provided with a hand lever 59 and with a cam section 10.. Shaft 55 may also be operated in-- directly by'a depending arm 1| (Fig. 1) as will hereinafter be described. There is preferably a counterweight box at l2 adapted to receive counterweights of any desired value to tend to oscillate shaft-55 inadirectiom to bring its kni'vs ,.5l into engagement with the work. It will, of

course, be understood that the bias of the counterweight, as well as any manual operation of shaft 55 is communicated through the gear segments 51 and 58 to shaft 55 to produce correby refcutting disks'GI sufiiciently so that the core shaft will roll into station A, as shown in Fig. 1.

The same oscillation of the rock shaft which allows the core shaft to enter station A will also result in the retraction ofthe chuck shown in Figure 11. This chuck does not engage ,the squared end 08 of the core shaft to drive the core shaft positively. The end of the core shaft is station A to station B by reason ofthe fact that the filled core shaft moving along guideway M from station B encounters the arms II thereby oscillating rock shafts 05 and 60 to remove their respective supporting knives BI- and 62 from beneath the core shaft at station A, thereby allowing the latter to drop through'guideway 42 into station B, to replace the filled core shaft which is in process of removal from that station.

As clearly appears in Figure 1, the core shaft at station B rests in a pocket in the guideway it.

simply engaged frictionally by the end of a spin- 0 7 die 13 which rotates in anti-friction hearings in a chuck sleeve 14 biased outwardly by a spring 140. The spindle 12 carries a driving gear 15 at the center of which is a cam follower l0 rotatably mounted and positioned to be acted upon by the cam I0.

The drive for .the chuck spindle I2 is shown in Figure 3. A separate motor, which may be con- At the time the unloaded core shaft falls into station B, the chucks which are later to engage this core shaft do not register with station B, having moved along guideway with the loaded roll.

The chucks. and 90 (Fig. 2 and Fig. '1) are mounted on arms 9| and 92 which are pivoted at opposite sides of the machine frame by reason of their disposition at the opposite ends of a the rock shaft 93. Counterweights 94 extend to carry the rock shaft in a. position in which the arms 9| and 92 project upwardly.

stantly in operation during the use of the ma chine, is provided'at I1 and transmits motion through belt 18 to a pulley I9 'on sleeve 80 which also carries pinion 8| meshing with gear 15 and having a-wide enough surface to permit the chuck assembly in sleeve It to move in and out under the bias of spring 140 and the pressure of cam 10. The pulley I9, sleeve 80 and pinion 8| constitute a unit .freely rotatable on the reduced extremity of rock shaft 66, being confined on the reduced end of the shaft by the collar 02, Fig. 11.

When the rock shaft 65 is oscillated counterclockwise as viewed in Figure 3 and Figure 1 to permit the' core shaft 0| to roll into station A, the thinportion of the cam sector 10 will be re istered with the cam follower button 16 to allow the chuck to assume itsextreme left position as viewed in Figure 11 under the bias of spring 14.

When the hand lever 69 is moved clockwise as viewed in Figure 3 and Figure 1 .to raise'the knives GI and 02 against the work, the work is lifted into contact with knives 00 and simultaneously the cam 10 acts on the cam follower button 16 to force the chuck assembly to the, right as viewed in Figure 11, thereby engaging the end of the chuck spindle 13 with the end of the core shaft to rotate the core shaft and the core sleeve with respect to the several knives, thereby subdividing the core tube into sections according to r the locations of the knife sets.

At its right hand end (as viewed in Fig. 11). the core shaft engages the slightly concave face ofa yieldable centering member 04 which isreciprocable in a housing cylinder 05 and is biased outwardly under the pressure of spring 06 to the extent permitted'by the disk 01 which engages sleeve 85 to limit the outward movement; The end member center in member. 84 and turns therein during the operations just described. These operations will ordinarily be performed while a winding operation is in progress at station B. The introduction of the core shaft into station A and the operations thereon at station A do not in any way affect the operation in progress at station B. However, at the conclusion of the winding operation at station B, the removal of the core shaft from that station with its load of fully wound rolls will meehanicallyeffecta transferofthecoreshaftfrom.

'by spring 91 toward a The chuck 89 (Fig. 2) has a socket complementary to the squared end of the terminal member 08 of the core shaft. Chuck 89 is rotatably mounted upon spindle 95 which turns -on antifriction hearings in the sleeve 96 which is biased thechuck with the core'shaft. The position of this sleeve and the associated chuck in response to the bias of sprin 91 is determined by a cam follower roller 98, rotatable on the upwardly projecting gudgeon 99, and also by the detent pin I00 (Figs. 3, 5 and 6) which, in the outward retracted movement of the sleeve 96 registers with a socket MI in the sleeve and enters the socket to hold the sleev retracted, the pin I00 having a spoolshaped head I02 with which interacts a lever I03 under the bias of compression spring I04.

The rock shaft 93 upon which the arms9l and ,92 are mounted carries a, hand lever I05 (Fig. 3)

41 of the core shaft finds its own by which it may be oscillated in aclockwise direction as viewed in Figure 3 to swing the entire chuck assembly forwardly toward the operator's station, thereby to move the core shaft from station B to station C. In the path of the cam follower roller 98 with which the chuck sleeve 98 isprovided, there is a, stationary cam I06 on-the frame of the machine which, as the core shaft approaches station C, retracts the sleeve 96 and the chuck 09 to free the end of the core shaft. The retracted sleeve is engaged by the detent pin I00 and'maintained in retracted position until, in the course of its movement to the left as viewed in Figures 3 and 5, it again registers with station B. At this point, the lower end of lever I03 strikes a fixed stop I00 on the machine frame; thereby oscilla'ting the lever in a direction to retract the pin I00 and allow the chuck and chuck sleeve to spring in under the bias of spring 91 to a position of engagement with the unloaded core shaft recently arrived through guideway 42 at station B as above described. v I

The chuck at the right of the machine is similarly retracted. Figure 2 shows the stationary cam I00 andthe cam follower roller 90 as above described. The specific construction of the chuck is different, However, and is best il--- lustrated in Figure 7.

The chuck so is rotatable on the spindle I n m I the sleeve III. The sleeve as a whole is reciprocable through the supporting arm and is biased into engagement with the end of the core shaft by compression spring III. The cam follower roller 90 and the detent-pin III with its position for engagement .of r

controlling lever I03 and fixed stop I08 (Fig. 5) are the same as those previously described in connection with the driving chuck at the other side of the machine.

In this instance, however, the spindle I I comprises a sleeve Within which the tube H4 is both rotatable and reciprocable. In the headed end of tube H4 is a gasket H5 of fiber, felt or other suitable material which bears rotatably against the end of the tapered portion 48 of the core shaft when such tapered portion is engaged in the conically tapered end of chuck 90. A key in the form of a plug H6 engages a slot in the tube IM to secure the tube non-rotatably to the external sleeve II and also to limit its axial movement. Across the opening at this end of the tube, is a cross pin III engageable with the stem of a valve I-I'Ia with which the air chuck H8 at the end of air hose H9 is provided. This chuck is a conventional chuck such as is used in filling automobile tires. Its valve Illa is biased to a seat not only by air pressure but by an internal spring shown in dotted lines in Figure 7. The chuck is clamped by a yoke I to the terminal member I2I which is screwed into, and acts as a part of, the main supporting sleeve III. Except when the end of the core shaft is engaged with the gasket I|5 to force the tube H4 to the right as viewed in Figure 7, the bias on valve IIIa will hold the valve closed and will push the tube ||4 to the left. However, when the respective chuck mounting sleeves are released by their respective detents to engage the ends of the core shaft at station B, the resulting pressure of the compression springs 91 and H2 causes the core shaft to exert upon gasket H5 a sufficient pressure to force tube H4 to the right, thereby unseating the valve IIIa and admitting air from hose I|9 into the duct 55 of the core shaft to inflate the sack 52 and thereby to dilate the said sack at the several openings 5| whereby the protruding portions of the sack engage the core 53 to fix the core securely for rotation with the core shaft during the winding operation. When not thus dilated by air pressure, the sack 52 has suflicient resilience to collapse and thereby to completely free the core tube or cores from the core shaft to facilitate the application of the core tube and the removal of the completed rolls.

The driving chuck 89 on spindle 95 receives motion in the following manner:

The pulley I on the main drive shaft I6 (Fig. 3 and Fig. 2) transmits motion by means of belt I26 to a pulley I21 which is carried loosely on the reduced end of shaft 93. Pulley I2! is provided at I28 with a clutch facing frictionally bearing against the face of pulley I29, the latter being independently mounted for free rotation upon shaft 93 and having a pressure nut I30 threaded to the rockshaft 93 for transmitting pressure through its bearings to vary the frictional effect of the clutch facing I28 in transmitting motion to pulley I29.

From pulley I29, which is coaxial with the rock shaft 93 upon which arm 9| oscillates, motion is transmitted through belt I32 to pulley I33 on the end of spindle 95.

The purpose of the slip clutch at I28 is to accommodate the differential driving forces applied to the several cores on core shaft 4| at station B during the winding of web material thereon. It will be noted from Figure 1 that at the commencement of the winding operation the core is in contact with the roll 32 over which the web is supplied. As the roll wound on the core in- (ill creases in size, the core shaft moves to the right, oscillating arms 9| and 92 clockwise as viewed in Figures 1 and 4. Assuming that the ratio of the belt and pulley driving connections to the core shaft chuck is appropriate in the first instance to rotate the core at the same peripheral speed at which the core tends to be rotated by the feed roll 32, over which the web is supplied, the gradual increase in the size of the roll will reduce the frictional driving ratio between feed roll 32 and the wound roll of web on the core shaft and the rate of drive to the chuck would be excessive if the excess movement were not accommodated by slippage at the clutch above described.

As is usual in machines of this character, I provide a counter I35 for stopping or, at least, de-clutching e main drive motor I0 when the correct amount of paper has been wound on to the cores carried by the core shaft 4| at station B. The drive shaft I36 of the counter is connected in any suitable manner as by means of chain I31 and sprocket I38 with the main drive shaft I. Such a counter usually contains a switch (not shown) and the electrical supply conduit I39 enters the counter and is connected through the counter to the conduit I40 leading to motor.|8.

When the motor stops, the operator will actuate lever I05 clockwise, as viewed in Figure 3, thereby swinging the arms 9| and 92 and the still chucked core shaft along guideway 44 toward station C. As the core shaft moves along the guideway, it encounters the arms 1| depending from rock shaft 65 thereby oscillating rock shafts 65 and 66 and dropping from station A a, core shaft upon which the core tube has been freshly slit into core sections of the desired length. Due to the fact that the core dividing operation is performed in the same machine in which the winding is accomplished and due to the fact that the cutting knives 60, 6| and 62 which act on the core are aligned with the cutting knives 33 which slit the web, it is possible to assure absolute alignment of each web section with its respective core, making hand alignment of the cores unnecessary. In the past, where the cores have been pre-cut and threaded separately on to the core shaft, unavoidable irregularities have made it necessary for the operator to align the cores by hand as it has sometimes been impossible to align them at all. By eliminating these problems, the present machine not only gives results of improved accuracy, but also accomplishes considerable time savings.

As the loaded core shaft moves from station B to station 0, it stretches an unbroken line of web from the rolls on the core shaft to the supply roll 32. The unloaded core shaft dropping through guideway 42 from station A to station B falls on to this web which is thereby confined under tension beneath the freshly cut cores. When the loaded core shaft reach s station C and is unchucked from the arms 9| and 92, as above described, a cam I45 on the rock shaft 93 engages at the last movement of the rock shaft a water supply valve stem I46, the water supply valve controlling the admission of water under pressure to a pipe I41 (Figs. 1, 12 and 2). This pipe is provided at suitable intervals of perhaps eight or ten inches with spray nozzles I48 enclosed within a flat walled tapered housing I49 having an upwardly directed slot for projecting a flat spray directly against that portion of the paper web which is held under tension beneath the cores scribed, I have reduced by .the latterlbeing I ment of the invention the guideway ase'aooo of the core shaft newly arrived at stationB. Since the web is under tension, it will, if made of tissue or other soft .paper, immediatel break when wet. Moreover, the wet end will adhere to the cores on the core shaft at station B. The wet end trailing from. the full rolls on the core shaft at station C can readily be wound on to the full rolls by the operator who will turn the rolls by hand for this purpose, whereupon the wet end will adhere to the full rolls to preventthe full rolls from coming unwound.

Meantime the chucks will be returned to station 3 and engaged with the empty core shaft and the motor re-started and clutched to the machine to commence a new winding operation. The operator, after lifting the full core shaft from station C, will slide the completed rolls therefrom, thread an unslit core tube on to the empty core shaft, place the tubed core shaft in the guideway 40 and manipulate the hand lever 69 to open the cutting disks 5| and 52 and thereby to admit the core shaft to station A. He will thereupon slit the cores at station A by pulling on the hand lever $9, by which time the winding operation is approximately complete and the cycle will be repeated, the full rolls being removed from station fore,

is moved out to station C, tensio i between the full rolls I13 and the supply cylinder 32 a portion of the web as previously described. The unloaded core shaft' drops into sioned intervening web. Thereupon, by manipulating lever III, the operator rotates the pinion I69 on rock shaft I55 and, although the sleeve I58 is not positively connected with the rock shaft, the oscillation of the rock shaft-is transmitted to the leeve through the torsion springs I I15 to elevate the arms l5l and the parts connected therewith, thereby raising the web about the unloaded core shaft and the freshly cut cores thereon to the position indicated in dotted lines in-Figure 13. 'When the receptacle comprising members I56 and I59 receives the knife I50, the web is severed. The receptacle strikes the bar IIi upon which the. knife is supported and, therecan go no farther. This brings the sleeve I56 and the arms I51 to rest and continued movement of the rock shaft I55, accommodated by B, automatically substituting at station B the core shaft with newly slit cores from station A.

In winding wax paper, the water out off is unsuitable. Therefore, for wax and other relatively water impermeable papers, I use a cut off shown In Figures 13 to 15 with which, in a machine otherwise corresponding exactly to that above'deapprordmately onehalf the time required to wind wax paper rolls.

In the device shown in Figures 13 to 15, a sta tionary knife I56 spans the machine in close' I proximity to the feed roll 82 over which the web is supplied and upon which it is slit.

Upon the rock station '13, the loaded core shaft having been're-.

moved to station C as shown in Figure 13. Approximately loaded core shaft at station B, each of the arms I51 has a slot I5I of arcuate form in which there is oscillatable a mounting member I52 which has the shape of a sector of a tube. Carried by the I mounting member I62 and projecting therefrom in a direction representing a minor chord of the arcuate slot I6I. is a tucking blade I55. Foroscillating the mounting member I62 in slot I6I and thereby advancing the lug member I62 is provided with a gear segment I55 driven by an idler I5'I from a pinion I68 moimted on the rock shaft'l55. The rock shaft I55 is. in turn, provided with a pinion I58 meshing with a segment I15 at the end ofiever III, pivoted to the frame on. stud I12. operations described in During the winding connection with ,the first mentioned embodi- (and which are here con-' ducted in exactly the assembly of the arms 4! in the position indicated in same manner), the entire dotted lines-in shaft I55 which spans the ma- .chine immediately beneath station B is a sleeve I51 is cut away to provide atucking blade, the mount- I51 liesretracted beneath.

torsion springs I15, results in the transmission of motion through gears I56 and I51 to segment I66 whereby the split tube mounting member I62 oscillates through its arcuate guide slots to the position shown in Figure 14 in which the tucking blade I65 has forced the severed end of the web into the bite between the supply cylinder .32 and the cores-53 upon the core shaft at station B. The starting of the machine will now cause the end of the ,web to follow around thecore and thereby to commence a new winding operation,

whereupon the lever III will be-moved counterclockwise as viewed in Figure 13; The torsion springs I15 will first restore the tucking blade and its semi-tubular mount to their original'relative positions at the bottom of the arcuate slots I5I grid-thereafter the continued movement of the lever will result in retracting the entire assembly to its original dotted line position as indicated in Figure 13.
