Claims. (Cl. 242-65) This invention relates to improvements in apparatus for winding web material into rolls.
The principal object of the invention is the provision of apparatus constructed and arranged to wind successive rolls of material from a web thereof which is continuously supplied to the apparatus.
The apparatus may be used for forming rolls from webs of various materials. Paper is a good example of material that is wound into rolls, but the novel features of the invention are not limited thereto.
As a web of paper comes from a paper making machine, calendering machine or other apparatus, it may be desired to wind said web into separate successive rolls directly as it comes from said apparatus.
According to novel features of the apparatus in a general way, a web of paper is wound onto an arbor or mandrel in a carrier by a rotating drum, and when the web has been wound into a roll of a predetermined diameter, the drum ceases its roll rotating function, the web is severed, the winding of a new roll on. a new arbor is commenced, the finished roll is discharged, and the new arbor is transferred to the carrier.
The apparatus of the invention is characterized by arbor carrier and supporting means for the roll winding operation which is guided and supported for movement away from the winding drum during the winding operation, and is arranged to discharge the arbor of a completed roll. At the same time, the arbor supporting means is such that when empty of the roll of material and its arbor, it is positionable to receive a subsequent arbor for the winding of a subsequent roll.
The roll of material being formed is rotated by the winding drum so that at all times the surface speed of the drum and roll coincide to obtain the most efiicient winding without unwanted wrinkles in the material of the roll. The gradually increasing diameter of the roll being wound functions in cooperation with the winding drum to move the arbor supporting means away from the winding drum and towards an arbor releasing or discharging position.
The apparatus of the invention is also characterized by means, in movement of the arbor supporting means relativeto the winding drum, to maintain accurate parallelism between the axes of the arbor and winding drum thereby to provide rolls which are uniform in all important respects.
As one novel feature of theinvention, means is provided for returning the arbor supporting or carrier means from its arbor releasing position to arbor receiving position for an arbor on which a roll of material is to be wound As another feature of the invention, the arbor carrier andsupporting means, during the roll forming operation, moves away from the winding drum without friction and theweight of thjeroll does not affect the friction between the drum and roll being formed so that the roll may be of the desired uniform hardness and other characteristics. ,Yarious ehanges and modification may be made in'the Patented Jan. 12, 1960 form of the apparatus without departing from the spirit and scope of the invention to be hereinafter disclosed in the presently preferred form thereof.

Referring now to the drawings more in detail, the novel features of the apparatus will be fully described.
To facilitate a clear understanding of the apparatus embodying the novel features of the invention hereof and the operation thereof, it will be described in connection with Figs. 1 and 2, which diagrammatically show the essential components of the apparatus.
A driving drum 2, which is rotatable upon a horizontal axis indicated by 4, receives a web of material W, such as paper, from a paper making machine, calendering apparatus, or other apparatus. The'said drum is in continuous rotation in the operation of the apparatus and may be rotated by any desired means.
Arms 6, at opposite ends of the drum, are swingable upon a horizontal axis indicated by 8 from the position shown in Fig. 1 in a clockwise direction, and reversely.
Said arms 6 are forked at 10 to receive and carry opposite ends of an arbor 12' on which the web is to be wound into a roll. The said arbor 12', as shown in Fig. l, is out of contact with the web W and the drum 2.
Arbor carriers or segments 20 are disposed at opposite sides of the apparatus and have peripheral edges 22 which are rollable along horizontal supports. Said segments are provided with seats or sockets 24 to receive the ends of an arbor from the arms 6.
Said segments 20 are slotted between inner and outer sides inwardly to bearing surfaces 24 which are concentric relative to the longitudinal axis of the arbor sockets and peripheries 22 thereof.
Pairs of flexible propelling members are provided for each segment 20. One of each pair of members is represented by dash lines 26 and one of the members of the other pair is represented by dot-dash lines 28.
Guide wheels 26' for the members 26 are rotatable on shafts which are disposed on horizontal fixed axes. Other guide wheels 28' and 28" and shafts for the members 28 are provided. Shaft 29 is for the wheels 28".
A pair of cylinders 30, one on each side of the machine, have pistons 32 reciprocable therein. Piston rods 34 of the pistons carry end members 36. Shafts 38 are provided for transversely spaced wheels 40. The wheels 40 are located at opposite sides of the machine on shafts 38 which are independent.
The members 28 have upper end portions in the slots or grooves of the segments 20, and are suitably anchored to said segments at 42. Said members extend from the segments around wheels 28' and 28", around wheels 40, and at opposite ends are anchored or fixed at 44 to stationary parts of the apparatus.
Each of the members 26 are disposed in the slots or grooves of the segments 20 and said ends are secured to the segment at 44. The opposite ends of said members 26 extend around wheels 49 and are secured at 46 to stationary parts of the machine.
The members 26 and 28 will be in the form of flexible chains but cables or the like will be equally well adapted for the purpose of the invention.
Where chains are used, all of the wheels referred to may be in the form of sprockets if desired. Sprockets 28" are fixed to shaft 29, and may be rotated by turning said shaft so as to simultaneously roll the segments 20 on the supporting means therefor and away from the dnim 2.
As the segments 20 roll on their supports in a clockwise direction, the arrangements of the parts is such that the wheels 48 and the pistons 32 are moved to the left from the position of Fig. 1.
A pair of stabilizers are provided for each segment 20. One such stabilizer 50 of each pair has one end anchored to each segment at 52, and an opposite end anchored or fixed at 54 to a fixed part of the apparatus. The other stabilizer 56 of each pair has one end anchored at 58 to the segment, and an opposite end anchored or fixed at 60 to a fixed part of the apparatus.
The stabilizers of the pairs thereof will preferably be in the form of metal bands. As the carriers or segments 20 roll in one direction, one band will be wrapped or wound on the peripheries of the segments while the other band will be unwound. In reverse rolling, the reverse will be true.
The stabilizers function to control the segments as they roll thereby to maintain the axis of the arbor 12, in the sockets of the segments parallel to the axis of the drum 2 in all postions of the segments.
An air jet conduit 66 transversely of the apparatus and is provided with parts for directing jets of air upwardly between the drum 2 and a roll of material R on an arbor 12 carried by the segments.
In Fig. l, with the drum 2 in rotation, the web W is being wound on a rotatable arbor 12 in the sockets 24 of the segments 20. The roll R being formed bears against the drum so as to be rotated thereby. As the roll R builds up or increases in diameter, the segments 20 roll clockwise on their peripheries away from the drum 2, so that the axis of the arbor therein moves horizontally in a straight line to the right.
Fig. 2 shows the components in about the transfer position where the roll R is spaced from the drum about 3" or so. When the arbor is filled to the desired diameter, the members 26 and 28 are operated by pistons 32 of cylinder 30 to move the roll R to the right to provide the space between the roll- R and drum.
- The arms 6 are swung clockwise through a rather small initial angle to bring an arbor 12 therein into contact with the web W on the drum for rotation thereof by said drum- Jets of air are directed upwardly between the drum 2 and roll R so as to lift or blow the web from the drum and balloon or loop it upwardly as indicated by 70 and bring it around into contact with the rotating arbor 12. The ballooning of the web causes it to double upon-itself somewhat, as indicated by 72, and the doubled portion is caught in the bite of the arbor 12' and drum whereby the rotating arbor winds 12 up the web. The web W between the arbor and roll R then becomes taut so that it is ruptured and separated from the roll R.
Subsequent to rupture of the web, segments 20 are moved clockwise through their full travel to discharge the filled arbor 12 onto supporting means of the machine, or suitable other means. Such movement of the segments is accomplished through the members 28 by applying pressure to the right hand end of cylinders 30.
With the arbor 12 free of the segments 20, pressure is applied to the left end of the cylinders to move the pistons to the right. Such movement of the pistons and rolls 40 causes the members 26 to roll the segments 20 counterclockwise to position the sockets 24 thereof in arbor receiving position where said sockets are adjacent the drum.
The arms 6 are further rotated clockwise by means of the gearing so that the arbor 12 being rotated by the drum to wind up the web has its opposite ends deposited in the sockets of the segments. The roll partly formed in the arbor lies against the drum and is rotated thereby for continuing and completing a roll from the web. The pressure between the roll and drum can be controlled by the pressure at the left end of the cylinders 30.
The supporting structure of the apparatus includes horizontally spaced similar side frames which are preferably formed from various shapes of structural steel. It will be understood that the elements may be secured together in any well known manner such as by welding, riveting, bolting or the like. These side frames will preferably be mounted on suitable foundations or at least on a suitable support so that the components may be maintained in operative relationship, and of course the side frames may be suitably secured together in horizontally spaced relation, as may be desired.
Otherwise the side frames may be of castings or formed in any desired manner.
For purpose of disclosure, the side frames 69 are provided with elongated horizontal sole plates 70 and with horizontally spaced lower stringers 72 on said sole plates.
Vertically extending supporting fixed pillars, such as 74, have lower ends secured to the stringers 72, and upper ends secured to upper elongated stringers 76. Upper elongated horizontally disposed plates 78 are carried by and secured to the upper stringers 76.
Similar bearing housings, such as 80, for the drum 2 and arms 6 are secured to upper sides of the upper plates 78 of each side frame. One said bearing housing is shown in Fig. 6.
A shaft 82 for the drum 2 is journalled in the housing by means of an anti-friction bearing 84, and an end cap 86' secured to the housing holds the bearing 84 in place. Sealing rings 86 are held in place by plates 88 as is usual.
A ring 90 is rotatable on the housing which is held against axial displacement therefrom by means of a ring 92 secured thereto. A central part of the arm 6 is held to the ring 90 by a ring 94. The arm 6 is thus mounted for swinging in such manner that the shaft 82 rotates on axis 4 while the arm swings on axis 8. That is, the axes of the arm and shaft are relatively spaced.
With a bearing housing 80 secured to each side frame, the shaft 82 extends between the side frames, and has the drum 2 fixed thereto which is disposed between said side frames. The shaft 82 and drum may be rotated by any desired means so that the web to be wound into a roll is delivered to the apparatus.
The gear segments 14 are fixed to the lower ends of the arms 6. The driving pinions 16 therefor are fixed to the shaft 18 which is rotatable in bearings such as 96 secured to the leftmost support 74, see Fig. 3. The shaft 18 may be rotated by a motor, crank or such other means as may be desired.
The upper plates 78 of the side frames are provided with elongated slots 79, in which the arbor carriers or segments 20 are disposed, see Fig. 8. The segments have wear plates 20 on their opposite sides for slidably engaging opposite sides of the slots 79 as they roll on their supports. Said segments are provided with slots 98 between opposite sides thereof as in Fig. 5, which terminate in curved surfaces 24, shown clearly in Fig. 3.
Elongated horizontally extending guides 106 are disposed in vertical planes and are secured to the plates 100. Said guides are adapted to engage and guide peripheral side portions of the segments 20 as they roll back and forth relative to plates 100. a
The stabilizers 50 and 56 of the pairs thereof for each of the segments 20 are flat flexible metal strips or bands, and are adapted to lie on the plates 100. One stabilizer 50 of the pairs thereof has upper ends secured at 52 to the segments 20, and opposite ends secured to the ends of the guides 106 by plates 54. The other stabilizer 56 of the pairs thereof has one end secured to the segments at 58, and opposite ends secured to the ends of the guides 106 by plates 60.
The peripheries of the segments 20 engage the stabilizers. As the said segments roll in opposite directions, the stabilizers of the pairs thereof are alternately wrapped or wound on and unwound from said peripheries, and are arranged to maintain the axes of the sockets and drum in accurate parallelism.
The cylinders 30 have members 108 secured to the rails 72 of the frames, and the piston rods 34 thereof are slidable in guides 110 secured to said rails 72. End members 36 of the piston rods have shafts 38 to carry the wheels 40.
A chain 26 and a chain 28 is provided for each segment 20. As shown in Fig. 1, an upper end portion of each chain 28 is disposed in the slot 98 of a segment, and is secured thereto at 42. Said chains 28 extend over wheels or pulleys 28' and 28", the lower member 28" being in the form of a sprocket. Shafts 112 and 29 are rotatable in members 114 and 116 secured to vertical members 74. The shaft 29 at least extends between the side frames, and may be rotated by any desired means, preferably however by action of pistons 32. The chains 28 extend over the wheels 40, and are anchored by bolts 118 secured to members 120 which in turn are secured to the rails 72.
Each chain 26 has one end secured to a segment at 44, and extends over pulleys 26' and 26" on shafts 122 and 124 of vertical plates 126 of each side frame. The opposite end portions of the chains 26 extend over the wheel 40 and are anchored by bolts 46 to members 118, of the side frames.
The arbor 12 includes an elongated shaft 134 on opposite ends of which is a rotatably mounted bearing 136 which is held against axial displacement. The bearings 136 are receivable in the seats 24 of the segments 20, and are of such dimensions as to be out of contact with the upper plate 78 as the segments roll therealong in forming of a roll R. Bearings 138, in which opposite ends of the shaft 134 are freely rotatable, are receivable in the slots of the forked ends of the arms 6. A central portion 140 of the arbor, on which a web is wound to form a roll such as R, is preferably tubular and is fixed to said shaft 134 in any desired and suitable manner.
Various means may be provided for supplying air for rupturing the web as the full roll thereof is formed. For illustrative purposes, the conduit 66 is indicated which may be provided with longitudinally spaced ports, and suitably connected to an air supply. Said conduit will extend between the side frames to underlie the web W.
From the foregoing, it will be observed that the roll R being formed on the arbor in the segments, is in contact with and rotated by the drum. As the roll increases in diameter, the segments roll clockwise away from the drum on their peripheries to the finished size of the paper roll. The segments are readily rolled clockwise to move a completed roll from out of contact with the drum, and further to its arbor and roll discharging position. The arms swing an empty arbor into contact with the drum, so that the web is looped into contact with an arbor and caught between the bite of the said arbor and drum whereby the arbor commences winding a roll so that the web is ruptured. The segments release the arbor of a completed roll so that the ends of the arbor are supported by the upper plates of the supporting structure for removal thereof from the'apparatus. The segments are returned to arbor receiving position adjacent the drum, and the arms swing clockwise to transfer an arbor, on which a roll is partly formed, so that opposite ends are seated in the sockets of the segments.
Various means may be employed for rotating the drum and the shafts 18 and 29, as well as for supplying pressure to the cylinders all to the end that the components of the machine may operate in the desired time relation. Such changes may be made as will adapt the apparatus for use with webs of various materials, and therefor it is desired to be limited, if at all, by the appended claims rather than by the foregoing description of the present preferred form of the invention.
