Claims. (Cl. 83-407) This invention relates to cutting device andmore particularly to devices for cutting elongated paper rolls at spaced intervals. Each perforated strip is then wound about an arbor about a paper or cardboard core positioned on the arbor until the roll reaches a predetermined cross sectional diameter, whereupon the core with that portion of wound paper stripping is removed and a new core is placed in position on the arbor and the winding continues in such fashion until the paper strip is consumed. Controlling the size ofthe rolls and the positioning of the cardboard cores may be performed manually or automatically.

Strips of toilet tissue break very easily when being wound about receiving arbors. In practice when one of the 8 or strips which are simultaneously wound around the receiving arbors breaks, costly delays are ex perienced and loss of considerable paper results.

It is first an object of the instant invention to provide a device which completely revises the conventional practice followed in making paper rolls for consumer use, thereby eliminating the costly operations of first unwinding the paper from a roll, then slitting the unrolled paper and re-winding it into smaller rolls, and eliminating the costly waste of paper resulting from breaking of the perforated strips of paper during re-winding.

In accordance with the instant invention there is pro.- vided a device to which the paper is delivered in elongated perforated rolls wound about a single elongated cardboard core resembling a long mailing tube. Initially, the paper delivered to the device comprehended in the instant application is wound to substantially the same cross sectional diameter as that of the finished rolls, so that upon cutting of the elongated roll into transverse segments of selected length no further unwinding or rewinding is required.

It is, therefore, an object of this invention to provide a device which has a mechanism for feeding paper rolls of selected diameter unto a cutting bed which advances against a plurality of rotating knives which cut the roll paper into selected roll segments.

It is a further object of this invention to provide a device for cutting perforated rolls into roll segments of selected length and which has a plurality of holders for holding the paper during cutting and permitting yielding of the paper to preclude damage resulting from friction during the cutting operation.

It is a yet further object of this invention to provide a device for cutting paper rolls and the like into segments of selected smaller roll lengths in which there Patented Apr. 18, 1961 are a plurality of longitudinally spaced rotatably mounted cutting knives which successively cut end segments of the advancing paper roll.

A still further object of this invention is the provision of a device having a bed and a plurality of rotating cutters extending through said bed and being movable relative to each other so that a paper roll carried on the bed will be successively cut to providea plurality of smaller rolls of selected dimension.

Other and further objects of this invention will'become apparent from the following description and appended claims, reference being had to the accompanying drawings and numerals of reference thereon.

On the drawings:

Fig. 5 is an enlarged view looking at the device from above and illustrating the cutting bed and roll cutting operations.

Fig. 6 is a view taken substantially on the line 66 of Fig. 2 and illustrating the mechanism for feeding the rolls unto the cutting bed.

Fig. 7 is an enlarged side view of one of the plurality of roll holding elements taken on the line 77 of Fig. 2.

Fig. 8 is atransverse sectional view taken substantially on line 88 of Fig. 3.

Fig. 9 is a transverse sectional view taken substantially on line 9--9 of Fig. 3, and

Fig. 10 is a transverse sectional view taken substantially on line 1010 of Fig. 3.

Referring now more particularly to the drawings, the device comprises an elongated frame, generally designated by the numeral 20, and portions of which form legs 21 which are arranged in opposed pairs to support the frame above the ground or floor level. An endless conveyor, generally designated at 22, is driven longitudinally of the frame 20. In the embodiment illustrated, the conveyor comprises a plurality of endless transversely spaced link chains, of which there are six, identified respectively as 22a, 22b, 22c, 22d, 22a and 22], as illustraed in Fig. 4. However, the device is not limited to six conveyor components or to the fact that the conveyor components are link chains because the width of the bed formed by conveyor 22, in a given device, will be dependent upon the length of the primary roll 45 which such device is adapted to handle; and any equivalent conveyor construction may be substituted for the 1 chain conveyors illustrated in the drawings provided a bed of the transversely spaced elements is formed.

The chains comprising conveyor 22 are-disposed in spaced relationship for reasons to become apparent hereinafter. They are actuated by means of a prime mover which is illustrated as an electricenergized motor, generally designated as 23. The electric motor 23 is suitably secured on a pedestal 25 which forms an extension of the frame 29, as clearly illustrated in Figs. 4 and 9. Power from the motor 23 is transmitted through motor shaft 26 to a pulley wheel 27 secured on the end of said shaft 26. From said pulley wheel 27 a pair of pulleys or belts 28 transmits the power to a wheel 29 which is rigidly secured on the end of shaft 30 of a gear reducer mechanism generally designated as 31, and only the housing of which is shown in the drawings. The force at the output end of the gear reducer mechanism 31 is transmitted to shaft 24, which is illustrated in Figs. 1, 3 and 4, the shaft 24 being journalled in opposed bearing compothe shaft 24 and pull the conveyor 22 in the direction of the arrow in Figs. 1, 3, 5, 6, and 7. In other words,

the left end of Fig. 1 is the discharge end of the frame.

In the embodiment illustrated, there are six sprocket wheels 33a, 3311, 330, 33a, 33c, and 33], one for each of the correspondingly designated sprocket or conveyor 'chains 22. As illustrated in Fig. 4, a plurality of sprocket wheels, generally designated as 34, are rigidly secured to a shaft 35 which is journalled in bearing components car- 'ried on the frame 20. Six of such last-mentioned sprocket wheels 34a, 34b, 34c, 34d, 34a and 34 are shown, one

for each of the conveyor chains 22. The sprocket wheels 34 are mounted below thecutting bed of the frame in a position selected for directing the course of the conveyor 22 toward the head of the frame 20, as

- will show in Fig. 1.

The sprocket wheels 33 are operably supported by the frame 20 at the discharge end of the frame in positions aligned to keep the conveyor chains, 22 level and straight from the head of the frame- 20 to the discharge end thereof. The alignment'of said sprocket wheels 33 is with a plurality of sprocket wheels generally designated as 36, and of which there are six in the device illustrated,

: being identified as 36a, 36b, 36c, 36d, 36c and 36f. The sprocket wheels 36 are rigidly secured on a shaft 37 which is journalled in opposed bearing blocks 38. Said bearing blocks 38, of which only one is shown, are illustrated in Fig. 2.

To direct the course of the conveyor chains 22 from the sprocket wheels 34 to the sprocket wheels 36 a 'plurality of sprocket wheels, generally designated as 39,

are rigidly secured on the shaft 40, which is illustrated in Fig. 1. The shaft 40 is journalled in opposed journalling elements 41, only one, of which is shown in Fig. 1.

, In the embodiment shown, there are six of such last-men tioned sprocket wheels 39a, 39b, 39c, 39d, 39:; and 39],

one respectively for each of the conveyor chains 22.

.The portions of the conveyor chains 22 being carried from right to left with respect to Fig. 1 between sprocket wheels 36 and 33 provide a substantially flat bed or table; and to maintain the chains 22a, 22b, 22c, 22d, 222 and 22f properly spaced and aligned throughout their course through the bed a plurality of elongated tracks are pro- .vided. Said tracks are generally designated as 42 and specifically identified as 42a, 42b, 42c, 42d, 42s and 42;,

- one for each of the chains 22. Said tracks are rigidly j secured for the support thereof to transversely extending frame components 43, as illustrated in the drawings.

The primary elongated paper roll intended to be severed by the device into a plurality of finished rolls or segments has wound upon its elongated core a pro-determined length of paper corresponding to the length of paper desired in the finished roll product. The paper on the primary roll, if preferred, may have been previously perforated at appropriately spaced intervals so that sections thereof may be detached easily from the finished roll. In accordance with the instant disclosure, a plurality of primary rolls, generally designated as 45, are successively fed by means clearly illustrated in Figs. 2, 6 and 7, onto the bed of conveyor 22. As each roll 45 progresses from right to left, with respect to Fig. 5, its initial opposite ends 44:: are severed, then again two end 44b portions of the remaining primary roll 45 are severed, and successively until finally the remaining portion of the primary roll is divided into two segments 44c.

Having reference to Fig. 2, it is seen that a bin or hopper 46 is secured on the frame 20 above the bed formed by the conveyors 22. A plurality of primary rolls 45 are deposited in the hopper and the same. are d by one upwardly the inner ends of arms 47 are withdrawn from at spaced intervals unto the bed formed by the conveyor-r secured on the shaft 49 the lower or outer end of a thrust arm 51 which at its opposite end is retained between a track or guide 52 carried on the hopper. The thrust arms 51 are angularly disposed and are in parallel alignment with each other; and each thereof bears on a cam 53 which is eccentrically secured on a transversely extending shaft 54. The shaft 54 at its opposite ends is journalled in bearing blocks 55 which are secured toopposite sides of frame 20, as illustrated in Fig. 2.

As the shaft 54 rotates thrust arms 51 are successively raised by virtue of the cams 53 and'rapidly lowered under the action of tension spring 56 one end of which is secured to one of the links 48 and the opposite end of which is secured to one of the guide members 52, as illustrated in Fig. 2. As the thrust arms are moved the hopper 46 for. a sufficient time to permit the stack rolls 45 to drop onto thrust arms 51, the device being so 'reciprocated that when the lowermost roll 45 has dropped to the thrust arms 51 the arms 47 will rapidly and simultaneously move back into the hopper 46, under the action of the spring 56, to occlude the hopper 46 and hold the remaining rolls 45, as illustrated in Fig. 6. As

the thrust arms, are lowered toward their lowest position,

a roll then deposited thereon will be picked up by an advancing roll holder on the conveyor 22. The length of the arms 47 is such that they will continue to support the rolls 45 in the hopper until arms 51 have been again sufliciently raised to support the dropped stack.

Each arm 47 moves back and forth through the hop per apertures and is guided between an upper end portion of a respective track'or guide 52. The inward movement of each of said arms 47 is limited by engagement of the respective bearing plates 57 -in the angles 58 defining the-bend in the arms 47. Each hearing plate 57 is secured orintegral with a respective guide 52, as illustrated in Fig.2.

To provide rotation for the shaft 54 a sprocket whee 59, illustrated at the right of Fig. 1, is rigidly secured on the shaft 54. Sprocket wheel 59 is actuated by power transmitted from the rotation of the shaft 37 to a sprocket wheel 60 rigidly secured on shaft 37. A chain 61 operably connects sprocketwheel 60 with sprocket wheel 59. Each primary roll 45 released from the hopper is dropped onto a roll holder. The roll holders extend transversely of the conveyor and aplurality of such roll holders, each longitudinally spaced from the other thereof, are provided, as illustrated in Fig. 5, so that at any one time a plurality of .primary'rolls 45 are simultaneously in the process of being severed on the bed formed by the conveyors 22 and are in varyingphases of segmentation, as illustrated in Fig; 5. The designation roll holder is ageneral term and for the purpose 22. Each back rest 65 is ofangular construction and has a roll-engaging portion 65a and a base 65b, a's' 'illus trated in Fig. 7; Eachbackrestbase 65a is isecured to its respective chain in conveyor 22 by fasteners 66 such as bolts and nuts or the like. 'Th'efront rest 640i each holding component 63 is spaced from the respective back rest 65 a distance which will permit the primary roll 45 to be engaged and held therebetweemas illustrated in Fig. 7, but spaced from theconveyor 22. Each front rest 64 comprises angularly disposed roll-engaging portion 64a and a base 64b which is secured to its respective chain in the conveyor by fastening means 67 such as nuts and bolts. To guide the rolls 45 into proper :position as they successively drop from the hopper the 'front rests positions 64a are disposed at approximately a 50 angle from the bed formed by the conveyor 22. The front rests 64 in each roll holder 62 fall substantially in a transversely extending plane.

As clearly illustrated in Figs. and 7, the roll engaging portion 65a is substantially at right angles from its base portion 65b. However, each portion 65a is bent so that at its inner end itis closer to its respective roll engaging portion 64a of the corresponding front rest 64. In other words, as we move from either side of the device medially the outer ends of each back rest portion 65a are divergent or bent rearwardly from the roll-engaging portion 64a of the front rest 64. The reason for such construction is to permit bending of the roll 45 as the segments thereof are being cut. That is to say, if no provision is made to accommodate the thickness of the cutting tool, the end surfaces of the segments in engagement with the cutters will be scorched or otherwise damaged.

The foregoing construction permits each of the portions 44a, 44b and 440 during the cutting thereof to yield and move outwardly in its respective holding component 63.

In accordance with the instant invention, a device is provided in which the cutting of the rolls 45 occurs in successive stages so that from the primary roll 45 initially two end portions are severed and as each primary roll travels along the bed successive end portions of the primary roll 45 are severed until a segment of the primary roll remains intact should be equivalent in its longitudinal dimension to substantially one or two finished rolls. If such last remaining portion is twice as long as a finished roll, it is then severed in half, and therefore only a single cutter is required and accordingly, adjacent the discharge end of the device illustrated, a single rotatable cutter 68 (which is preferably a circular knife) is mounted. Said cutter 68 is disposed in the vertical longitudinal axial plane of the device in the path of the moving primary rolls.

The rotating central cutter 68 is rigidly secured on a transversely extending arbor or shaft 69 which is journalled in opposed bearing members 70. The bearing members 70 are carried on members of the frame '20, as illustrated in Fig. 9. Power for the rotation of arbor or shaft 69 is transmitted through a pulley wheel 71 which is rigidly secured on the arbor 69 and which is rotationally actuated by force transmitted through a friction belt or pulley 72. The radius of the knife 68 is such that it will permit a clean severing of the primary roll.

The friction belt 72 receives its power through a wheel 73 which is rigidly secured on shaft arbor 74. The arbor' 74 is journalled in a pair of bearing elements 75 which are carried on members of frame 20, as illustrated in Fig. 8. The arbor 74 has secured thereon in spaced relation a pair of opposed cutters suchas circular knives or the like 76 which are adapted to engage the advancing primary roll 45 just beyond the medial pair of holding components 63, as illustrated in Fig.8.

In the embodiment shown, the cutters 76 are adapted to completely sever the ends of the primary roll 45 after the first two segments have been removed in the next preceding cutting operation.

plurality of bearing elements 78 which :are secured to members of frame 20. The arbor 77 has rigidly secured thereon a pulley wheel 79 which drives friction pulley or belt 80. Said pulley 80 is operably connected to a pulley wheel which is secured-on arbor 74 whereby said arbor 74 is rotated.

The rotational force of the shaft 77 is received from a pulley wheel 81 rigidly secured on said shaft 77. The wheel 81 is operably connected by pulley or friction belt 82 to a pulley wheel 83, seen in Fig. 3.

Pulley wheel 83 is secured on a transversely extending shaft 132 which is suitably journalled in said frame. Shaft 132 has secured thereon a pulley wheel 133 which is operably connected to a pulley wheel 135 secured on shaft 84 by means of pulley belt 134. Shaft 132 is preferably journalled in bearing components 85 in the lower portion of the frame 20, as illustrated in Fig. 10.

Secured outwardly of the frame 20 at end of the shaft 84 is a large flywheel 86 operably connected to a second prime mover means, such as motor or the like 130.

We wish it understood that we do not intend limiting the invention to two prime movers. Obviously, by mechanical variations, easily apparent, at single prime mover means could beemployed, if desired.

In the instant embodiment the pulleywheel-86 is actuated by motor 136 through a V-belt 131. v

A pair of cutters, illustrated herein as circular knives 87, are secured in opposed positions on the shaft 77. As shaft 77 rotates said cutters 87 will be caused to rotate and sever any oncoming roll 45 to provide finished rolls 44a from the outermost end portions of roll 45. That is to say, the cutters 87 engage just inwardly of the outermost pair of holding components 63.

From the foregoing it will be apparent that a primary roll 45 of any selected dimensions can be accommodated and successively segmented into finished rolls, by making obvious physical changes.

For example, without modifying the-dimensions of the particular embodiment herein illustrated, an additional pair of finished rolls of paper could be segmented merely by adding a pair of circular knives on a shaft; and rotating so that the added knives engage outwardly of the end holding elements 63 to thereby sever a pair of rolls from an elongated primary roll '45.

Each of the cutters in the instant disclosure may be of the same construction and design and in the embodiment illustrated herein each has a substantially straight cutting flat 88 and a bevelled cutting flat 89 terminating in a cutting edge. As illustrated in the drawings, in each of the cutters except the cutter 68, the straight cutting flat 88 is medially or inwardly disposed and the-beveled fiat 89 is laterally or outwardly disposed to preclude damage to the roll ends. It is of no significance whether the'flat 88 or 89 of the center wheel 68 is disposed to the right or to the left because both of the finished-roll portions 44c will yield in their holding components 63.

Each of the cutters is provided with a sharpening or grinding mechanism comprising a pair of grinders such as cup wheels or abrasive cups, the rims of which are intermittently engageable with the opposite'edge flats 'of the respective cutters. The rim of each abrasive cup 90 which engages the straight flat 88 of its respective cutter lies in a plane substantially parallel to the respective straight fiat 88. The rim of the abrasive cup 91 which engages the opposite flat of its respective cutter lies in a plane intersecting the plane of the cutting edge of its respective cutter. The cups 90 and 91 of each grinding mechanism are slightly spaced from each other so that projection of the plane of their respective rims will meet at a point slightly below the edge of the cups 90 and 91. Such disposition provides for a fine cutting edge on each cutter when same is disposed between the cups and engaged by its respective grinding mechanism. 7

Each of the cups 90 is relea'sably secured to a bracket {192 and each of the cups 91 is releasably secured to a bracket 93 which is angularly disposed to its mate. The

cups 90 and 91, may be rotated when desired by changing their positions upon re-mounting on the brackets 92 and 93, respectively, to provide even erosion on the abrasive Fig. 8. The pairs of brackets 92 and 93 with-their respective cups 90 and 91 are pivotally mounted on a rock shaft 96, illustrated in Fig. 10. The brackets 92 and 93 of each pair thereof are drawn together by a tension spring 97, which, at its opposite ends, is secured to its respective brackets 92 and 93. Secured between each pair .of brackets 92 and 93 is a slotted boss 98, the slot of which acts as a bearing for its respective spring 97, as illustrated in Figs. 8, 9, and 10. Each spring 97 will yield as its respective grinding mechanism is brought into engagement with its respective rotating cutter, however, maintaining suflicient tension to assure the formation and maintenance of a sharp edge on its cutter. a

The device is reciprocated in such a fashion that 1nv termittently the rock shafts 94, 95 and 96 are rotated in and out of sharpening position. The shaft 94 is journalled in a pair of opposed bearing elements 100 which are secured to members of frame 20, as illustrated in Fig. 9. The shaft 95 is journalled in a pair of opposed bearing elements 101 which are rigidly secured to members of frame 20, as illustrated in Fig. 8. The shaft 96 is rockably borne in bearing 102 which is secured to a l member of frame 20, as illustrated in Fig. 10. Each of the shafts 94, 95 and 96 are operably connected to an elongated longitudinally reciprocable arm 103, illustrated in Fig. 1. The rocking arm 103 is operably connected to the prime mover means, as will be more fully described 7 hereinafter.

The rocking arm 103 is movably secured against a vertically extending and slotted bracket-like lever arm 104, as illustrated in Fig. 1.

-' a'rm'104 is by means of a fastener or the like 106 having an enlarged head and which fastener or pin 106 is slid-" able within the limits of slot 107 in lever arm 104. The

' lower end of the lever arm 104 is fast on shaft 96. A

Securance against lever fulcrum element 108 has its lower end fast on shaft 96 and its upper end is slotted, as illustrated at 109. A pin or boss 110 is rigidly secured at its inner end on lever arm 104. As the arm 103 rocks to and fro its movement is limited in part by the limits of slot 107. The reciprocating force of arm 103 is translated into movement in lever arm 104 which will rock about the fulcrum element 108 but will also move as an arm within the limits of 1 the slot 109 to intermittently cause rocking of the shaft 96 to move the grinding mechanisms supported by said i shaft into and out of sharpening engagement with the cutters 87, respectively.

The rock arm 103 also is movably mounted adjacent bracket-like lever arm 105 to which 'it is secured by means of a fastener 111 with an enlarged head. The fastener is movable within the limits of slot 112 in said lever arm 105. The lower. end of the lever arm 105 is rigidly secured on the rock shaft 95. A fulcrum element 113 has its lower end rigidly secured on the rock shaft 1 95 and is provided at its upper end with a slot 114 which I limits the rotational or rocking movement of the lever arm 105 by virtue of engagement with pin 115 which at its inner'end is secured on the lever arm 105 and Which I engages in said'slot 114, as'illustrated in Fig. 1. Accordingly, as the'rock arm 105 moves to the left with respect to Fig. -1 the shaft 95, like the shaft 96'is rotated counterclockwise and the sharpening mechanisms mounted on said shafts 95' and- 96 are brought into sharpening engageiii ment with the respective knives carried on the- shafts 95 and 96. I

Rocking of the shafts 95 and 96 in a counter clock wise direction will cause drawing of arm 116 to the right with respect to Fig. 1 because the inner end of this arm is rigidly secured on shaft 95. Such movement in arm 116 causes the lower end of link 117, which at said lower end is rigidly secured to arm 116, to move tothe right. Accordingly, arm 118, which is pivotally connected to the upper end of link 117 and rigidly connected to the shaft 94 at its opposite end, will move downwardly and rock shaft 94 clockwise thereby causing the sharpening mechanism carried on shaft 94 to be brought into sharpening engagement with knife 68.

To impart movement to the rock arm 103 a sprocket wheel 119 is rigidly secured on the shaft 40 hereinbefore described. The force of said sprocket wheel 119 is transmitted to a sprocket wheel 120 through a sprocket chain 121 to thereby reduce the speed of the shaft 40.

*shown) carried in the frame.

The sprocket wheel 121 is secured on a stub shaft 122 which is conventionally journalled in bearings (not A sprocket wheel 123 'which is rigidly secured on the stub shaft 122 transmits the rotational force of the last mentioned shaft to sprocket wheel 124 through sprocket chain 125 to cause rotation of shaft 126 on which the sprocket wheel 124 'is rigidly secured, as illustrated to the right of Fig. 1.

The shaft 126 extends transversely through the frame and is journalled therein. It has secured thereon in a position aligned with the end 127 of the elongated arm 103 a cam 128 so that as the shaft 126 rotates the cam will intermittently engage the face of the arm end 127 to move it to the left with respect to Fig. 1. Such movement accordingly causes the grinding cups or cup shells,

heretofore identified, to engage their respective cutters.

The arm 103 is withdrawn from sharpening position 'under the action of tension spring 129 as soon as the face of cam 128 begins to disengage the end 127 of arm 103 and accordingly the sharpening elements disengage the cutters.
