  • FIG. 2 is an enlargement of the encircled portion of FIG. 1;
  • FIG. 3 is a fragmentary perspective view of the inventive machine taken essentially from the left side of FIG. 1;
  • FIG. 4 is an elevational view of the machine viewed from just inside of one of the side frames so as to disclose the essential working parts;
  • FIG. 5 is a sectional view such as would be seen along the sight line 5-5 as applied to FIG. 4;
  • FIG. 6 is a fragmentary perspective view of the stacking portion of the machine and corresponds to a view taken along the lines 66 of FIG. 4;
  • FIGS. 7-10 are schematic views showing the operation of the various finger assemblies on stacks of web segments
  • FIGS. 11 and 12 are sectional views taken along the sight lines 99 and 10 applied to FIG. 4 in the vicinity of the stack remover.
  • FIG. 13 is a graph plotting cam contour as a function of cam rotation-cams being employed to control the movement of the aforementioned finger assembles in developing stacks.
  • the numeral 20 designates the frame of the machine which, in accordance with conventional practice, includes two relatively heavy side members as at 20a and 20b in FIG. 1.
  • the apparatus for delivering the webbed segments into the stacking station or area Usually provided as part of the machine frame is the apparatus for delivering the webbed segments into the stacking station or area.
  • the forming anddelivery mechanism need not be that illustrated here and may take a variety of forms. In certain aspects it is described in greater detail in the aforementioned Patent No. 3,254,889.
  • the superstructure designated D in FIG. 1 shows this generally.
  • the web in FIG. 4 is designated by the symbol W and is seen to pass between a cutoff roll 21 equipped with knives 22 and operating against an anvil roll 23. Both of these rolls are advantageously rotatably supported on the frame 20 and driven by gears 21a and 2311, respectively (see FIG. 1).
  • the cutoff roll 21 illustrated here is a two-time roll and operates to transversely sever the web W at discrete intervals.
  • the roll 23 also has a web-adhering function through the use of internal vacuum. Thus, the leading edge of the web W is caused to follow the surface of the roll 23 to the point designated 24 in FIG. 4.
  • the web W has followed the periphery of roll 23 only part way to the point 24.
  • a previous web segment W has been removed from the roll 23 under the influence of a folding roll 25.
  • the folding roll 25 has vacuum ports at the points designated 26, 26a, 26b and operates to remove a middle portion (i.e., half-Way along its length) of a web segment from the roll 23. This develops folds F, and F in the segment W.
  • the web W advantageously may be longitudinally folded (as by the mechanism D) so as to provide a stack of double folded hankies, napkins, etc.
  • the segment W then passes between the surface of the roll 25 and that of an ironing roll 27 so that a transversely folded web segment is delivered by orbiting packer fingers 28 to the stack defining station.
  • the packer fingers 28 operate to strip segments from the roll 25 by moving into annular grooves 29 thereofbefore the segments W reach that portion of the roll 25. This stripping position is seen in dotted line in FIG. 4 and is designated 28'.
  • Web segments (folded or otherwise depending upon the type of delivery means) follow a path generally designated 30 and which also is seen in FIGS. 3 and 5.
  • a second path is designated 30 and will be appreciated that as many side by side paths can be utilized as is convenient in an installation.
  • the path 30 would be that associated with the righthand set of fingers and grooves 28 and 29 in FIG. 2 while the path 30' with the lefthand set.
  • the stack defining means provided herein are essentially the same in each path.
  • the path 30, as seen in FIG. 4, is arranged at about 45 from the vertica1.-However, for the sake of ease of description, it will be described as being a generally downward path, but those skilled in the art can appreciate that the path may have many other directions than that shown and described.
  • FIG. 7 is schematic and occurs a short time after the configuration of elements seen in FIG. 6.
  • the packer finger mechanism is seen to be moving upwardly after the assemblies 31 and 33 have begun to clamp a completed stack against the assemblies 32 and 34.
  • the packer mechanism is delivering a subsequent segment 39 (see FIG. 7) against the upper segment 40 of the just completed stack.
  • FIG. 8 shows that the stack of say ten hankies confined between the upper set of finger assemblies 31 and 33 and the lower set of finger assemblies 32 and 34 is compacted in FIG. 7 but is not so compacted in FIG. 8.
  • the orbital movement of the finger assemblies can also be appreciated from a consideration of FIG. 13.
  • the upper curve represents a projected profile of the cam employed to develop the movement of the finger assemblies in the direction of the path. As mentioned previously, for the sake of convenience, this can be considered up and down.
  • the down movement can be considered in the direction of the path of web segment movement while the up movement can be con sidered against the flow of Web segments.
  • the lower curve in FIG. 13 represents the contour of a second cam which is responsible for the movement of the assemblies transverse to the direction of the path 30. In other words, after the finger assemblies reach the bottom of that portion of their orbit which is in the path 30, they must move laterally outwardly from the path before moving upwardly to enter the path in the movement indicated schematically at 47 in FIG. 10.
  • An orbit or cycle can be considered to start at the point generally designated 48 in FIG. 13 where a given set of finger assemblies is at the very top of its orbit. From that point there is a movement downward designated 49 and a corresponding inward movement (so labeled) and indicated by the numeral 50 applied to the lower curve. At this juncture, the given finger assembly set is ready to receive subsequent web segments and support the same for the formation of a stack. The initial web segment is deposited at a time corresponding to the extreme lefthand portion of FIG. 13 and designated 51 relative to the upper curve and 52 relative to the lower curve.
  • the means for orbiting the finger assemblies is generally designated 60 and includes the mechanism shown essentially in the lower portion of FIG. 4, particularly the splined shaft 61 at the righthand central portion of FIG. 4this being selected as exemplary for ease of description.
  • the splined shaft 61 provides the means for guiding the orbital movement of the finger assembly 31. It will be understood that in the illustration given, a splined shaft will be provided for each of the four finger assemblies 31-34. However, in connection with the shaft 31, it will be noted that it is rotatably supported on the frame 20 by means of bearings 62 and 63.
  • the splined shaft 61 is inclined at 45 to the vertical, thus paralleling the direction of the path 30.
  • the finger assembly 31 is provided as part of an arm 64 (see also FIG. 3) extending at right angles to the length of the splined shaft 61 and is slideably mounted on the shaft 61 by means of a block 65 (see the central portion of FIG. 5) Still referring to FIG. 5, it is seen that the shaft 61 is provided with a gear segment 66 which is fixed or pinned thereto. This is responsible for the horizontal component of the orbital motion and the actuating mechanism therefore will be described in detail hereinafter.
  • the numeral 67 designates generally a linkage system for this vertical component. It includes a cam 68, the contour of which is seen in projected form in the upper curve in FIG. 13. It will be appreciated that the cam 68 is rotatably mounted on the frame and is powered by belt 68a (FIG. 1). Usually in machines of this nature, a single, highpowered motor is used with interconnecting gears, gear reducers, etc. and many of these have been omitted as being conventional expedients. Riding against the periphery of the cam 68 is a cam follower 69 mounted on an arm 70.
  • the cam follower arm 70 is shownin FIG. 4 only as a line, i.e., in schematic form so it is not to obscure with unnecessary detail the remaining portion of the drawing.
  • the cam follower arm 70 is fixed to a transverse pivot or rocker shaft 71 mounted in suitable pillow blocks 72 provided as part of the frame 20. Also fixed or pinned to the pivot shaft 71 is a pivot or rocker arm 73 (shown schematically in FIG. 4). Pivotedly interconnected between the arm 64 and the end of the rocker arm 73 is a linkage 74 (still referring to FIG. 4).
  • This oscillation includes, for example, the portion of the upper curve in FIG. 13 designated 49 where the finger assembly is moving downwardly and inwardly to the position designated 47 in FIG. 10.
  • the particular portion of the cam contour which serves as an actuator or velocity control for this phase of the operation is designated 75.
  • the corresponding cam contour for this purpose is designated 76 and 77 in FIG. 4.
  • a second cam 78 for the other set 36 of finger assemblies is designated 78 in FIG. 4. It will be appreciated that the cam 68 through the cam follower 69 and rocker shaft 71 is responsible for the up and down movement of both of the finger assemblies 31 and 33 constituting the first set 35. A linkage assembly including arms like those designated 73 and 74 is provided for the finger assembly 33.
  • the means for moving the other set 36 of finger assemblies 32 and 34 includes a cam follower 79 (still referring to the bottom of FIG. 4) cam follower arm 80 and first rocker shaft 81, suitably journaled in the frame 20.
  • a second rocker shaft is provided at 82 and is responsive to the oscillation of rocker shaft 81 by virtue of interconnecting gears 83 and 84this being provided to reverse the movement of the cam follower 79 inasmuch as the same is provided on the opposite side of the cam shaft 68b from the cam follower 69, it being appreciated that all of the finger assemblies follow the same orbit.
  • This output of the rocker shaft 82 is transmitted through a rocker arm 85 and linkage 86 to the arm 87 (see also FIG. 3) associated with the finger assembly 32.
  • the arm 87 is fixed to a block 88 which is slideably mounted on a splined shaft 89.
  • cam and linkage system 90 to achieve the in and out movement of the finger assemblies, we employ a cam and linkage system generally designated 90 in FIG. 5.
  • the control for this movement is provided in the form of a cam 91.
  • a cam follower 92 is positioned for movement in accordance with the contour of the cam 91 and is rotatably mounted on a cam follower arm 93 (again schematically represented).
  • the cam follower arm 93 is fixed to a rocker or cross-shaft 94 as is a rocker arm 95.
  • the other end of the rocker arm 95 is pivotedly connected to a link 96 which in turn is pivotedly connected to a block 97.
  • the block 97 has at one end a gear segment 98 and is fixed to the splined shaft 61.
  • the gear segment 98 is employed to deliver the same movement to a second gear segment 99 mounted on the splined shaft 100.
  • the splined shaft 100 is associated with the finger assembly 33 constituting the mate of the finger assembly 31 in making up the set 35.
  • Both of these finger assemblies 31 and 33 operate from the cam 91.
  • a second cam (not shown) is mounted coaxially with the cam 91 and is employed for imparting the in and out movement to the finger assemblies 32 and 34 by virtue of a suitable connection with the splined shaft 89 and 101.
  • linkages 103 and 104 These operate to pivot additional splined shafts as at 61 and 89' associated with a parallel path 30.
  • the machine illustrated in the drawing is intended .for delivering two streams of stacked paper handkerchiefs.
  • two separate folding devices are provided at the very top portion of the showing in FIG. 1 as at 105 and 106 for the paths 30 and 30, respectively.
  • the webs are longitudinally folded for ultimate delivery through troughs 107 and 108, respectively at the left center portion of FIG. 1.
  • These troughs or ways are also identified in FIG. 3.
  • the folding roll 25 is equipped with a gear 25a (see FIG. 1) which, like the other gears pictured, derives rotational power through a series of gears, ultimately, in the illustration given, from a drive pulley 109 on the rear side of the machine and pictured in the upper righthand portion of FIG. 1.
  • the folding roll 25 is equipped with the previously referred to vacuum grooves 29 (see particularly FIG. 3) which are coupled to a vacuum pump by means of a manifold 110 (see the lower righthand side of FIG.
  • the frames 20a and 20b are cut out as at 111 (see the central portion of FIG. 1) for the ready removal of the folding roll 25.
  • This cut out 111 provides the basis for the showing of the interior workings in FIG. 2.
  • the finger assemblies 31 and 32 alternate in moving downwardly so as to define stacks. As the finger assembly 32 reaches the nadir of its orbit, it is moved laterally outwardly from engagement with the stack, i.e., out of the paper and then upwardly to a position above the finger assembly 31.
  • the fingers 31 and 32 are arranged as illustrated, we offset or interleave them as shown for readily passing one another.
  • the fingers 32 in the operation depicted in FIG. 2 are withdrawn from supporting relation with a given stack of webs only after the clip 45 attached to the stack remover chain 44 has removed a completed stack.
  • an improved stack defining mechanism characterized by the fact that it includes:
  • each assembly of a given pair being aligned with one assembly of the other pair to provide two sets (35, 36) of finger assemblies, said finger assemblies being sized to extend over a minor edge portion of a given segment (39) in said path so as to present a substantial central portion of said given segment for frictional engagement with a subsequent segment (40) moving into said path, and means (60) operably associated with said finger assemblies sets for sequentially orbiting said sets with a portion of each orbit being in said path, and including a retrograde movement said means being arranged and constructed to limit the movement of said finger assemblies toward each other so as to necessarily present said substantial central portion.
  • an improved stack defining mechanism characterized by the fact that it includes:
  • each assembly of a given pair being aligned with one assembly of the other pair to provide two sets (35, 36) of finger assemblies, said finger assemblies being sized to extend over a minor edge portion of a given segment (39) in said path so as to present a substantial central portion of said given segment for frictional engagement with a subsequent segment (40) moving into said path, and means (60) operably associated with said finger assemblies sets for sequentially orbiting said sets with a portion of each orbit being in said path, said means including an actuator to position a set commencing said orbit portion in compacting relation with a stack supported on the other set whereby said central portion is caused to upstand relative to said commencing set finger assemblies during at least the initial build up of a succeeding stack.
  • said means includes a second actuator (76) for accelerating the movement of each set shortly prior to the end of its movement in said orbit portion to compact a preceding stack just prior to engagement of said preceding stack with said stack remover.
  • said means includes a third actuator (77) for reversing the movement of each set for a predetermined time immediately following the compaction of said preceding stack whereby the stack following said preceding stack is supported free of engagement of said stack remover, said stack remover being arranged and constructed to engage said preceding stack only after the beginning of the reverse movement.
  • each finger assembly includes a plurality of finger parts projecting into said path, the finger parts of one assembly of a given pair being offset (41, 42) from the finger parts of the other assembly of said given pair whereby said parts are adapted to pass each other during sequential orbiting thereof.
  • said means includes four splined shafts (61, 89, 100, 101) rotatably mounted on said frame, finger-assembly carrying arms (64, 87) movably mounted on said shafts (61, 89) means interconnecting pairs of said shafts for cooperative action in rotating the same, and gear means coupled to said arms and cooperative rotating means for orbiting said finger assemblies.
