Definitions

  • the winder in the above-identified application has been used for winding large rolls of web material to form parent rolls, i.e., rolls having thousands of feet of web material.
  • a feature of the invention of the earlier winder was the use of an air jet and knife arrangement to effect transfer and thus eliminate the need for adhesively securing the leading edge of a severed web to a new core. This is particularly important in the winding of plastic webs such as polyethylene.
  • FIG. I is a perspective view of apparatus embodying teachingsof the invention, and showing one end of the machinery; r v
  • FIG. 2 is another perspective view of apparatus revealing the other end
  • FIG. 3 is a schematic side elevational view of certain operative portions of the machine of FIGS. 1 and 2 with which the instant invention is concerned;
  • FIGS. 4-6 are further schematic views essentially similar to FIG. 3 but showing the parts thereof in differentoperational positions;
  • FIG. 7 is a perspective view of the central portion of v FIG. 2.
  • the numeral 10 designates generally the machine frame.
  • the frame is essentially a box-like structure supporting a plurality of rolls in the interior thereof and which are driven through gearing generally designated 11 from a motor (not shown).
  • the numeral 12 designates a discharge platform or way wherein finished retail sized rolls of plastic web material -such as polyethylene are directed out of the frame 10.
  • the numeral 13 designates a core hopper for supplying cores to be wound in sequence and discharged from the other side of the machine on the way 12.
  • a roll is in the process of being wound at 14 in the winding stations of the turret 15, the shaft of the latter being generally designated 15a in FIG. 3.
  • the turret 15 includes a plurality of mandrels or arbors which, when the turret rotates, orbit through a plurality of positions or stations.
  • a four-arbor turret is employed with arbor stations for unloading being represented by'the numeral 16, for core loading as at 17, and for transfer as at 18. Stations 17 and 18 are indicated also on FIG. 2.
  • the turret is arranged for rotation about the axis of the shaft 15a so as to bring the various arbors thereof sequentially through the transfer station, winding station, etc. It will be appreciated that the invention can also'be employed to advantage where the cores are eliminated and the web wound directly on the mandrels or arbors, viz., core means.
  • Web material W (still referring to FIG. 3) is brought into the frame from a parent roll source (not shown) by means of feed rolls l9 and 20.
  • the rolls l9 and 20 are suitably driven from the gearing 11 and serve to feed or advance the web W at a constant rate toward the turret for winding.
  • the numeral 21 in FIG. 3 designates an auxiliary roll which is mounted for free rotation in the frame 10, but with its axis fixed. It will be noted that in FIG. 3, the path of travel of the web W issuch as to be partially but substantially wrapped around the auxiliary roll 21. In the illustration given, the diameter of the auxiliary roll 21 is the same (O.D.-) as the core (or mandrel,when no core is used) onto which the web is to be wound. However, three other rolls 22, 23, and 24 also serve to determine the path of travel of the web W from'the feed rolls 19-20 to the arbor in the winding station 14. The rolls 22, 23, and 24 are mounted on a sub-frame 25 (see FIG. 2) for oscillation to the positions 22', 23', and 24' as designated in FIGS. 4-6.
  • the machine condition corresponds to the middle of a winding cycle.
  • arbor 14a moves in a counterclockwise direction toward the winding station and thus permits a successive arbor 18a to arrive at the transfer station.
  • a previously wound roll, held by arbor 16a, is unloaded at the unloading station 16, and an arbor 17a is equipped or loaded with a core in the core loading station 17. It will be appreciated that more or less arbors may be used as desired, and also the various stations may be relocated.
  • the arbors employed include coni- I are axially movable relative to each other so as to be inserted into the open ends of a core.
  • One of such chucks can be seen in the central portion of FIG. 2 where the same is designated by the letter C.
  • the arbor means a single rod or mandrel extending across the web, with or without a core, in conventional fashion.
  • the mandrels shown in the above-identified Nystrand application Ser. No. 108,067 may be advantageously employed. In view of the air jet procedure for transferring the leading edge of this severed web, it is unnecessary to employ glue, so that the mandrels can be employed with or without cores.
  • the web is seen to be partially wrapped around the auxiliary roll 21, also partially wrapped around the first oscillating roll 22, and to a lesser degree partially wrapped around the second oscillating roll 23. Thereafter the path of web travel takes it past the third oscillating roll 24 where the degree of wrap is minimal.
  • the subframe 25 is mounted on a crank mechanism 26 (see FIG. 2) which oscillates the three rolls from the condition of FIG. 3 to that of FIGS. 4-6.
  • crank mechanism 26 occurs at the beginning stages of a new winding cycle wherein an arbor to which the web has just been transferred is moved toward the winding station 14 while a succeeding mandrel is moved toward the transfer station 18 from the core loading station 17.
  • FIGS. 3 and 4 An important difference between the configurations depicted in FIGS. 3 and 4 is the disposition of the web W.
  • the web has been virtually unwrapped from around the auxiliary roll 21 and has minimal contact with the first oscillating roll 22'.
  • the web has been substantially wrapped around the third oscillating roll 24 and around the core in the transfer position 18.
  • this partial wrapping of the web is referred to as pre-wrap since the web is wrapped on the new core but it is not yet being wound on the new core.
  • Pre-wrapping of the web on the new or rewind" core 18 at the transfer station facilitates a glueless transfer by trapping a leading edge of the web, after severing, between the core 18 and the web being fed on it during' pre-wrap. It will be observed from a comparison of FIG. 3 (prior to prewrap) and FIG. 4 (pre-wrap established) that the amount of pre-wrap established about the new core 18 by the roll 24 is greater than 180. When the leading edge of the web is trapped on the rewind core and transfer completed, the pre-wrap is removed. The rewind core is then indexed to the winding station and the roll 24 is moved to the position shown in FIG. 3 without changing thelengthof the web being fed to the turret.
  • FIG. 5 The initial step for achieving this is seen in FIG. 5 wherein a nose piece 28 is pivoted downwardly about a pivot center 29 so as to be directed toward and close to the nip 27.
  • the nose piece 28 can be seen in greater detail in the above-identified Nystrand application.
  • the nose piece 28 is seen to include a knife-receiving recess 30 and a bore or passage 31 for the delivery of a jet of air.
  • a knife 32 Also seen in schematic form but which can be seen in greater detail in the above-mentioned Nystrand application is a knife 32. As the knife 32 moves upwardly to the 32' position seen in FIG.
  • the web W is severed and the leading edge of the severed web is directed by the air jet issuing from the bore 31 into the nip 27 where it is picked up by the web partially wrapped around the roll 24' and held against the core on the mandrel 18a.
  • the gap at the nip 27 is relatively small, the surface of the roll 24' being about l/32 inch away from the surface of the core in the station 18.
  • the same degree of spacing exists in the configuration seen in FIG. 3 wherein the third oscillating roll is designated 24. Still further in FIG. 3, there is the same small spacing between the first oscillating roll 22 and the auxiliary roll 21, and this still further applies to the disposition of the first oscillating roll 22' relative to the auxiliary roll 21 in FIGS. 4-6.
  • the nose piece structure 28 i.e., the arms 33 which pivot around the pivot shaft center 29 with a further roll 34.
  • the function of the roll 34 is to be in pressure engagement with'the web partially wrapped on the surface of the core in station 18 (see FIGS. 5 and 6) to further insure the entry'of the severed leading edge into the nip 27.
  • the urging roll 34 includes a center shaft 35 (seen only in FIG. 5) which is driven so as to develop a surface speed on the shell 36 which is slightly greater than the lineal speed of the web W.
  • there is an impositive connection between the shaft 35 and the shell 36 by means of a bearing 37 so that there results only a slight urging of the composite roll 34 relative to the web W.
  • the knife 32' retreats to the 32 position of FIGS. 3-5 and the nose piece, or, more properly, the arms 33 rotate clockwise to the position of FIGS. 3 and 4 taking with them the urging roll 34.
  • FIG. 7 is an enlarged perspective view of the central portion of the machine seen in FIG. 2, the means for oscillating the rolls 22, 23, and 24 can be seen in greater detail.
  • the numeral 38 designates a pair of spaced-apart plates which rotatably support the three rolls 22, 23, and 24.
  • the three rolls are designated .via their shaft ends and from the position of the third oscillating roll 24 relative to the core equipped arbor 18a.
  • FIG. 7 corresponds to that shown in FIGS. 4-6, as contrasted to the showing in FIG. 3 where the third oscillating roll 24 is above the core in station 18.
  • the brackets 38 are supported by two pairs of cranks 39 and 40.
  • crank 39 is pivotally connected to the bracket 38, as at 42, while a similar connection is provided relative to the crank 40 as at 43.
  • each crank has its own rocker shaft, as at 44 for the crank 39, and 45 for the crank 40.
  • the drives for the two cranks include gears 46 and 47 which are engaged by adriven gear 48.
  • the gear 48 is driven by the gear 49 through an intermediate gear 50 and cross shaft 51.
  • the gear 49 is caused to rock or oscillate via the motion imparted to its shaft 52 through the rocker arm 53 (see the forward left hand portion of FIG. 7).
  • auxiliary roll 21 is supported on a fixed support 55 outside of the brackets 38.
  • the arm 56 of the turret which supports the core in station 18 can be seen in the lower left hand portion of FIG. 7 along with a gear driven friction clutch drive'57 therefor.
  • a frame a turret rotatably'mounted on said frame and equipped with a plurality of rotatable arbor means, means for rotating said turret to move each arbor means sequentially between a transfer station and a winding station, feed roll means rotatably mounted on said frame adjacent to said transfer station but spaced therefrom for advancing a web, an auxiliary roll rotatably mounted on said frame between said feed roll means and transfer station, oscillating roll means on said frame including first and second rolls for redirecting the path of travel of said web between said feed roll means and arbor means in said transfer station while maintaining substantially constant the length of web therebetween, means for moving said oscillating roll means between a first position of partially wrapping said auxiliary roll with the advancing web by means of said first roll and a second position to unwrap said auxiliary roll by said first roll and to form a nip with said arbor.
  • means in said transfer station by means of said second roll of said oscillating roll means, and means operably associated with said frame
  • said operably associated means includes a roll movable into contact with said web on one arbor means in said transfer station for urging the leading severed edge of said web against said arbor means and into said nip.
  • said oscillating roll means includes a third roll and crank means on said frame for moving said first and third rolls in a partial are about said auxiliary roll and for moving said second roll in a partial are about arbor means in said transfer station.
  • said arbor'means includes a pair of axially spaced-apart chucks insertable into the end of a core.
  • a frame in a web winding machine of high cyclic rate, a frame;- a turret rotatably mounted on said frame and equipped with a plurality of rotatable, driven arbor means; means for rotating said turret to move each arbor means sequentially between a transfer station and a winding station; means for feeding a web toward said transfer station at a constant speed; an auxiliary roll carried by said frame and engaging said web before i said web reaches said transfer station; movable roll means carried by said frame and including a first roll associated with said auxiliary roll and a second roll associated with an arbor means at said transfer station, said web engaging said first and second rolls before said web reaches said transfer station; means synchronized with said means for rotating said turret for alternately moving said movable roll means to.
  • each of said arbor means is substantially the same as the diameter of said auxiliary roll; and wherein said first and second rolls of said movable roll means are moved in an arc greater than 180 respectively about said auxiliary roll and arbor means in said transfer station between said first and second positions.
  • said movable roll means further includes a subframe movably carried by said frame for holding said first roll and said second roll in fixed position relative to each other such that when said movable roll means is in said first position, the prewrap of said web on said arbor means and the wrap of said web on said second roll is greater than 180, and the wrap of said web on said auxiliary roll and said first roll is removed, and when said movable roll means is in said second position, the pre-wrap of said web is removed from said arbor means and the wrap of said web on said second roll is reduced, and the wrap of said web on said auxiliary roll and said first roll is greater than 180.
  • the apparatus of claim 8 further comprising means for urging the leading severed edge of said web into engagement with said arbor means at said transfer station and beneath the web being wound thereon from said movable roll means to start a new rewinding roll.
  • a method of winding a web at high cyclic rate on a core without adhesive comprising: feeding said web at substantially constant speed; engaging an auxiliary roll and a first roll with said web before feeding said web to a core at a transfer station; moving a second roll in an arc about said arbor means in said transfer station to establish a pre-wrap of said web greater than on a rewind core at said transfer station; then severing said web and urging the leading edge between said core and and portion of the web being fed thereon to trap said severed leading edge; and simultaneously and equally moving said first and second rolls respectively in arcs greater than 180 about said auxiliary roll and said arbor means in a direction reverse of the first-mentioned movement of said second roll to remove the pre-wrap of said web on a started core and to increase the wrap of web on said auxiliary roll.
