17 Claims.
This invention relates to improvements in rewinding machines, and more particularly to a machine for continuously converting a Web of sheet material into relatively small rolls to be marketed as toilet paper, toweling, wax paper, or the like.
A general object of the invention is to provide a rewinding machine having novel means for effecting a transfer of the web from the wound rolls on one mandrel to the empty cores on a succeeding mandrel while the apparatus is operating at full speed.
A further object of the invention is to provide an apparatus having novel mechanism arranged to deflect and form a loop in a portion of the moving web which is intermediate one mandrel being wound and a next succeeding mandrel so that said web portion is advantageously positioned for subsequent cutting and for tucking of the web into the nip between the cores of the succeeding mandrel and an engaging roller.
A more specific object of the invention is to provide a device of the class described having transfer mechanism which is arranged to wrap a substantial portion of the length of the web on the cores of a succeeding mandrel while an advanced mandrel is still being wrapped, to-
gether with means for thereafter eiecting a complete overlapped tuck on the succeeding core substantially simultaneously with the severing of the web.
A further, more specific object of the invention is to provide a device of the classv described wherein there is an oscillatory transfer bar and wherein there is a tucking member movable with said transfer bar and mounted thereon for independent swinging movement at a predetermined tim'e in the cycle of operation.
A further object of the inventionis to provide a novel transfer member which is cam controlled in timed relationship with other cooperating parts of the machine. l
A further object of the inventiomis to provide a rewinding machine wherein the necessity of using moisture or an adhesive for applying a severed end of the web to a new set of cores is eliminated.
A further Object of 'the iin/elution is to pm-V vide a rewinding machine having a rotatable mandrel holder wherein means is provided for causing a periodic dwell during the rotation of the mandrel holder so that the transfer operationl may be more efficiently performed.
Other objects of the invention are to provide a'rewinding machine which is strong and Idurable, which is speedy in operation, which will accurately produce a roll of desired size, and which is otherwise Well adapted for the purposes described.
With the above and other objects in view the invention consists of the improvedrewinding machine and all its parts and combinations as set forth in the claims and all equivalents thereof.
In the accompanying drawings illustrating one complete embodiment of the preferred form of the invention,
Fig. 1 is an elevational view of one end of the machine;
Fig. 2 is a top plan view thereof;
Fig. 3 is a fragmentary view showing the opposite end of the machine from Fig. 1 and taken approximately on the line 3 3 of Fig. 2.;
Fig. 4 is a vertical sectional view taken approximately onlthe line 4--4 of Fig. 2 and showing the position of the parts as the transfer bar is moving forward toY deflect the web;
Fig. 5 is a view similar to Fig. 4 showing the position of the transfer bar -just before the web is transferred to the empty-cores;
Fig. 6 is a similar View showing the position of the parts at the time of actual transfer and just after the web has been severed; and
Fig. 7 is a similar view showing the transfer bar moving backout of the path of the mandrel holder.
Referring more particularly to the drawings the machine includes a suitable supporting frame having spaced side members I0 and `I I. A main shaft I2 is suitably journaled in the machine and is driven from an outside source through the pulley I3. 'I'he shaft I2 rigidly supports a bed roll Ill so that as' the shaft is driven the bed roll rotates. Referring to Fig. 1 the bed rol1 shaft I2 carries a bed roll gear I5 which in turn drives gears I6, I1, I8 and I9. The gear i6 is rigidly mounted on a shaft 20 for a pull roll 2I. The gear I1 is rigidly mounted on a shaft I22 for a perforating roll 23. The perforatingl roll is Aformed with one or more longitudinal rows of perforating projections 24 which cooperate with suitably located recesses in the bed roll to cause perforating of sheet material which passes between the bed roll and the perforating roll.
. The gear I8 is rigidly mounted on a shaft' 25 which drives a slitter roll 26. The slitter roll is formed with. suitably spaced circumferential frame.
. knives 21 which cooperate with circumferential grooves in the bed roll to cause slitting of the web to a predetermined number of widths. gear I9 is .rigidly mounted on a shaft 28 which drives a second pull roll 29.
Also rigidly connected to the bed roll shaft I2 is a worm 30 which drives a worm wheel 3|. The worm wheel 3| is rigidly mounted on a horizontal shaft 32 and the shaft 32 carries a bevel gear 33 rigidly von its outer end. The bevel gear in turn drives a bevel gear 34 mounted rigidly on a camshaft 35 which extends through theframe. The shaft 35 also carries av :rigidly mounted sprocket wheel 36 which is connected by a sprocket chain 31 with a sprocket wheel 38 mounted rigidly on a short shaft 39 vnear thev members consistsof three arms extending radially from a hub portion. The outer end of each arm forms a suitable bearing for a rotatable holder 41. Each of the rotatable holders 41 at one side of the machine is equipped with a drive pulley 48. Mandrels 49 are removablyinsertable, in any well-known manner, between the mandrel holders 45 and 46 in such a mannerthat when the drive pulley 48 for -a particular mandrel holder is rotated that the attached mandrel 49 will be likewise rotated. Each of the The mandrels 49 is adapted to receive a plurality of cardboard cores 50 in such a manner as to' cause rotation of .the cores when they are in position on the mandrel. s
Referring to Fig. 1, on the outer end of thebed roll shaft there is alsol mounted a friction drive pulley 5| which is connected by4 an endless belt 52 with a' smaller pulley 53 at the top of the The 'pulley 53 is mounted on a shaft 54 and said shaft carries on its inner end a pulley 55 (see Fig. 2). The pulley 55 drives an endless drive belt 56 which is' also threaded around a belt tightener pulley 51 and an idler pulley 58. That portion of the lengthvof the friction'drive belt 56 which extends between the pulley 55 and the idler pulley 58 is always deflected, in the manner shown in Fig. Lfby engagement of certain of the mandrel driving pulleys 48 therewith. Thus, movement of the endless drive belt 56 causes rotation of those mandrels whose drive pulleys are in engagement with the drive belt 56 at a particular time in the cycle of operation.
On the end of the cam shaft 35 opposite to the end which carries the bevel gear 34'is an internal cam 59 (see Figs. 2 and 3) having acam groove 68. Mounted for oscillation on astud 6| is an arm 62 formed with a gear segment 63 at its upper end. Connected to the arm 62 and extending toward the internal cam is a shorterl Figs. -4 to '7. A tucker pivot shaft 10 connects the transfer arms 68 and has its ends pivoted in said arms. The tucker pivot shaft has rigidly connected thereto, in spaced position, a plurality of tucker arms 1| and these tucker arms are connected at their free ends by a tuckerr bar "I2, The tucker bar 12 is normally maintained in an inactive position against a stop 13 by means of a coil spring 14. The tucker arm `shaft 10 is equipped with a projecting actuating lug 15. This lug is adapted to be engaged by one of the fixed studs 16 projecting from each mandrel holder arm, and this engagement causes movement of the tucker arms 1I and tucker bar 12 to the position of Fig. 6 when the transfer bar is in the position of said figure.
The transfer bar is formed with la longitudinal groove 11 which is cooperable with a knifel when the transfer bar is in the position of Fig. 6.
The knife 18 is Xedly suported between the sides top pulley -53 will cause driving of the friction drive belt 56.
A web of toilet tissue, paper toweling or other I sheetmaterial, which is fed from'a jumboroll 19, passes over the top of the pull roll I6 and then downwardly around the bed roll I4 between the latter and the rolls |1,'|8 and I9. The web then extends upwardly around the bed roll and beneath one of the mandrels to the uppermost mandrel whose cores are being wound. As the internal cam 59 rotates, it will, through the action ofthe cam follower vand arms 64 `and 62, gear segment 63 and gear66, cause rocking of the transfer arm shaft 61 to cause movement of the'transfer arms in the direction indicated by the arrow in Fig. 4. This causes deflection of that portion of the web which is between the mandrel being wound and the next succeeding mandrel. The rolls of paper on the uppermost mandrel of Fig. 4 are nearly wound. `Through the action of the cam 59 the transfer bar 69 continues its movement from the position of Fig. 4 to the position of Fig. 5, making a loop 80 in the web and wrapping it nearly aroundl the empty cores on the mandrel which is adjacent the bed roll. All of this time the drive pulleys 48 for the mandrel -which is being wound and for the next succeeding mandrel are in engagement with the drive belt 56, as shown in Fig. 1,
- 'and the mandrels and cores thereon are being rotated. The third mandrel is not being rotated i and is in the positionshown in Fig. 1 wherel the mandrel may be disconnected, the wound rolls removed and a new set of cardboard cores 50 inserted. Following the position of Fig. 5
the cam follower 65 (see Fig. '3) drops into a quick cam drop portion 8| of the cam groove to cause a quick forcing of the transfer bar from the position of Fig. 5 to the'position of Fig.- 6.
During this period one of the blank spots 44 of theintermittent mandrel holder drivegear is opposite the blank section 4I of the gear 40.
This causes a momentary dwell -in the rotation of the mandrel holder on the shaft 43. As the transfer bar 69 moves to the position of Fig. 6, the tucker actuating lug engages the stud 'I6 to cause swinging of the tucker arms 1I and tucker bar 12 from the position of Fig. 5 to the position of Fig. 6 against the tension of the spring 13. This causes the edge of the tucker bar 'l2 to tuck the looped web into the nip between the bed roll and the cores on the lowermost mandrel. Obviously this effects a complete surrounding of the empty cores by the web and an overlapping of the tucked portion so that upon continued rotation of the paper cores the webwill begin to wind and build up thereon. Simultaneously with the tucking operation the transfer bar engages the fixed knife i8 in the maginer shown in Fig. 6 to cause severing of the We The mandrel holder will again start to rotate after its momentary dwell and at the same time the cam control for the transfer bar will cause withdrawal movement of the bar in the direction indicated by the arrow in Fig. 7 and ultimately to a position clear of the rotating mandrels. As the newly started rolls on the lower mandrel move upwardly they are being continually wound,as indicated in Fig. '7, and by the time they reach the top position they are nearly fully wound. At the same time the fully wound rolls are being moved to the removal position by the mandrel holder.
It is apparent from the above that the winding operation is continuous even while the transfer of the web from one mandrel to another is a very advantageous positioning of the web just hesive to the web or empty -cores in order to start winding.
While it is preferred to use the intermittent drive for the mandrel holder, in order to obtain more efficient operation of the transfer mechanism, nevertheless the invention may be utilized in connection with a continually rotating man` drel holder.
Various other changes and modifications may be made without departing from thev spirit of the invention and all of such changes are contemplated as may come within the scope of the claims.
