- wIsooNsIN i ROLL WINDING MACHINE Application ined october s, 1927. serial No. 223,756.
This invention relates to roll winding machines and, more particularly, to machines for winding toilet paper rolls. In machines of this type, there is generally 5 'provided a' rotatable carrier in the form of a drum orreel, which carrier supports a plurality of core-holding elements, usually spindles, or mandrels. These spindles are removedfromxthe`V carrier in o rder t' place 0 cores thereon and, when the lwinding operation has been completed, they are again removed in order' to remove the wound rolls therefrom.
It is an object of this invention t0 render 5 automatic certainoperations which have heretofore been done bv hand.
It is a further object of this invention to provide a roll-winding machine with means for automatically applying cores to the core- 20 holding elements, which means, while automatic, shall always be within control of the operator.
p It is anotherobject of the invention to provide means for supplying cores to the 23 automatic core-applying means.
:a pleted.
Another obiectj of the invention is to provide mechanical means for stripping the wound rolls from the core-holding elements when the winding operation has been corn- It is a further object ot this invention to construct a machine embodying the features described and in which the cycle of operation includes four steps, as follows: Apply- 5 ing cores to the core-holding members, ap-
member are brought into contact with an adhesive-applying roller, the paper is being wound upon the cores on the next preceding member, and the wound rolls upon the fourth member are being stripped therefrom.
o Other obje-'cts and advantages of the invention will in part be obvious and in part more fully brought out as the description proceeds.
In the accompanying-drawings, we have illustrated an embodiment of our invention; but it is to be understood that the drawings are illustrative merely and that they are, in no way, intended to limit or restrict us to the details of construction therein shown.

l mounted. There are four such spindles each of which may be moved successively to a series of predetermined positions'by rotation of the carrier-f. It will be noted that the spindles are supported by'the carrier only at one end except when a spindle isin winding position at which time itl is supported at the other end by means to be hereinaftery fully n described.
The spindles 6 are rotatably mounted in the carrier 5 by the means illustrated in Fig. 13; Each spindle is provided with an'eXtension 7 bearing in the carrier and projecting a short distance beyond the carrier. To this proj ection is secured (a, disk 8, which, when the spindle is in roll-Winding position, contacts with a leather-faced plate 9 through whichrotary'motion is transmitted from the main drive shaft to the spindle. The bearings for thespindles( in thecarrier may be provided vwith anti-friction rollers 10.
The means for supporting. the spindles When4 in roll-winding position is illustrated .in Figs. 9 and 10. -This means comprises an arm 11 secured to the bracket 2 and provided at one end with'a bearing for the spindle supporting number 125- The member 12 is provided at one end with a conical nose 13 adapted to be received in an opening in the end of a spindle 6. Anti-friction rollers 14 are rovided in order to insure free rotation he member 12 in its bearing. The member 12 is maintained inlengagement with-the spindle by the action of the spring 15. rIVhe member 12 is also provided with a circumferential groove 16 which receives the yokeshaped end of a lever 17, by operation of which the member 12 may be withdrawn from the spindle against 'the action of the spring 15. The lever 17 is operated by a'handlev 17 at the right side of the machine which is connected to the lever by means of a rod passing through the hollow7 shaft 4. l
Upon rotation of the carrier, the spindles are successively brought into a' position in alinement with the automatic core-applying mechanism now to be described. This mechanism includes a supply hopper 1 supported by an arm 19 secured to a stationary bracket 20, as illustrated in Figs. 1a and 6. A plurality of rods 21 are located within the hopper and conform substantially to the shape thereof. The rods are rotated through a pulley 22 driven by a belt'23 and they are also reciprocated by means of the stationary cam rollers 24 working in the cam 25. Since it is not essential that this mechanism be timed with the othcr'operations of the machine, the pulley 22 may be driven from any convenient partof the machine. Cores are placed in the hdpper 18 in a disarrangcd mass and,by,mo tion of the rods 21, they are straightened out and descend by gravity in a vertical position through the tube 26 to the applying mechanism. The lower end of the tube 26 is composed of two hingedly connected sections 27 and 28, so that when the pins of the applying mechanism engage a core, itwill be drawn down from' a vertical to a horizontalposition 'to be applied to aspindle.l
The core-applying mechanism is best illustrated in F ig'. 4. This mechanism comprises a pair of sprocket ch-ains 29 trained about the,
sprocket wheels 30 and so arranged that one -chain travels in clockwise -and the other in counter-clockwise direction. Each chain is `provided with tightening means 31. The chains are also provided. with a pluralityA of pin blocks 32, rubber blocks 33, and stopblocks 34, all spaced along each chain at desired intervals. The pin blocks 32 carry pins 35 which, in the travel of the chains, engage a core 36 and draw it. out, of thev tube 26. By
" constructing the -lower end of the tube in two hingedly connected'section's, the core is permitted to fall into a horizontal position where it is eng/aged and frictionally held by the rubber blocks 33. The core is then carried by the chains and slipped onto the spindle 6.
Mounted adjacent the sprocket chains is a ratchet wheel 37 operated by a pawl y38 connected to a lever 39. One end o'f the lever 39 projects into the path of the stop blocks-34 and as one of these blocks engages the end of the lever the pawl'is operatedrtov rotate the ratchet wheelthe' distance of one tooth. v
The-. step-bystep motion lot 'the ratchet wheel 37 operates the timing mechanism best illustrated in Fig. 5. The ratchet wheel 37 is mounted on a small shaft or pin 40 on which is also mounted the-notched wheel 41. A spring-pressed pawl 42 engages the notch in the Wheel41 when the mechanism is in inoperative position. The pawl 42 is connected to a lever 43, the other end of which connects with a ,bell-crank lever 44. One arm of the bell-crank lever is connected to an operating rod 45 which is provided with a handle (not shown) at the right side of the machine. The other arm of the bell-crank lever operates the levers 46 and 47 which are the gear 53 which meshes with the gear 54 .on the shaft 55 andthe bevel gears 56 andv57. By this means the gears 58 and 59 are driven and transmit motion to the sprocket wheels 30 and their chains 29, as above described.
It is believed that the operation of the coreapplying mechanism will now be clear. The timing mechanism being ininoperative position as illustrated in Fig. 5, the operating rod 45 is rst actuated which simultaneously releases the brake 52 and lets in the clutch 51. Also, the awl 42 is withdrawn from the notch in t e wheel 41. The mechanism is now in'operation and the ratchet wheel 37 is rotated which, in turn, rotates the notched wheel 41. When the latter has made a complete revolution, the pawl 42 drops into the notch, thereby actuating the lever 43 which actuates the bell-crank lever 44 and the levers 46 and 47 to thereby'simultaneously let out the clutch and apply the brake. The mechanism is now restored to inoperative position.
It will be understood that the use of the automatic core-applying mechanism is not confined to the particular roll-winding machine herein described, but that it may be provided as an attachment for vother ma` chines of this character now in use.
When a spindle has been loaded with cores by the above described mechanism, the carrier is rotated to bring the cores into contact with a glue-roll 60, yieldably supported in bearings 61 provided with springs 62. The roll is supported in contact with glue or other adhesive in the trough 63 mounted upon the frame l by means of brackets 64.
When the winding operation has been completed, the carrier is again rotated and the wound rolls are stripped from the core-holding members or spindles by the mechanism illustrated in Figs. 1 and 11 which will now be described. A screw threaded rod 65 is journaled in bearings in the brackets 2 and 3 and is turned by the pulleys 66 and 67 through the clutch 68. The clutch is oper-- ated by the hand lever 69 connected to the shaft 70 passing through the rod 65. Mounted in the brackets 2 and 3 above the rod 65 is a guide rod 71. A pair of hingedly connected stripping fingers 72 have collars encircling the guide rod and threaded portions engaging the threads on the rod 65. The stripplng fingers are normally located at the right side of the machine in the open position indicated by dotted lines in Fig. 12. When the wound rolls are to be stripped from the spindles, the lever 69 is actuated which simultaneously closes the stripping fingers 72 by means of the lever 73 and lets in the clutch 68. The stripping fingers travel along the threaded rod 65 with their lower ends in contact with the wound rolls. At the end of their travel, the fingers are separated by the cam 74 and contact the stop block 75 whereby the clutch is disengaged the rotation of the rod 65 is reversed'and the stripping fingers are returned to their normal position vat the right side of the machine in contact. with the `adjustment stops 76. They remain in open posltion until the lever 69 is again operated.
Paper is supplied to our machine by the means illustrated in dotted lines in Figs. 2 and 3.4 This means includes the usual perforating, slitting and feeding rollers well known in the art and, since this forms no part of our invention, no further description need here be given.
In Fig. 14 we have illustrated diagrammatically the position of the spindles when the glued cores are to be brought into contact with the web of paper. As will be noted from this figure,when a roll has been wound and the carrier is rotated to present the rolls to the stripping mechanism, the web is elevated to such an extent that the following spindle will not contact therewith when in roll-winding position, indicated by It. To bring the glued cores into contact with the web w, the carrier is given a slight additional turn to present the spindle in the position indicated at R2. A part of the lue is thereby transferred to the web which is then severed by a mechanism well known in the art. The spindle is then returned to the position R and the winding operation is again started.
It is believed that the construction and operation of our machine has now been fully and clearly brought out and that its many advantages will be apparent to those acquainted with this type of machine.
