Description: UNSTABLE ARTICLE CONVEYING DEVICE WITH DIVERTER Field of the Invention This invention relates to an unstable article conveying device, and, more particularly, relates to a device with a diverter for conveying and diverting unstable articles, particularly unstable articles having a neck portion with a neck ring thereon, between a single path, or line, and multiple paths, or lines. Background of the Invention It is oftentimes necessary to convey articles between different locations, such as, for example, moving articles from one location to another in connection with various steps in manufacturing, storage and/or use of articles, or containers. Such articles must sometimes be moved in single line, or file, and at other times must be moved in multiple line or mass, between locations, and conveying systems for effecting article movement between multiple line or mass to single line and/or from single line to multiple line or mass are now well known. Particular difficulty has been encountered, however, in conveying lightweight unstable articles, such as plastic containers or bottles, from one location to another location due, at least in part, to the tendency of such articles to easily tip during movement. Where such articles have a neck ring, it is also known that such articles can be engaged and supported by elongated guides or movable flanges engaging the bottom side of the neck ring with movement of the articles along the guides being urged by air directed at the articles (see, for example, U.S. Patent Nos . 4,284,370 (Danler et al.), 4,724,035 (Mann et al.), 4,822,214 (Aidlin et al.), 4,938,636 (Aidlin et al.), 5,028,174 (Karass) , 5,100,265 (Mirkin) , 5,147,153 (Aidlin et al.), 5,161,919 (Smith et al.), 5,246,097 (McCoy et al.), 5,299,889 (Langenbeck) and 5,501,552 (Simkowski)) or with movement of the articles being urged by movement of the flanges (see, for example, U.S. Patent No. 5,937,998 (Priero) ) . It is also known that sections of fixed guides engaging the neck rings of the articles can be curved to cause a deviation, or turn, in the article flow path (see, for example, U.S. Patent No. 5,501,552 (Simkowski)), and that fixed guides engaging the neck rings of articles can be flexed to provide height adjustment of the article flow path (see, for example, U.S. Patent No. 5,630,679 (Simkowski et al.)). It is likewise also known that unstable articles being air conveyed along a path established by fixed position guides can be diverted to auxiliary, or other, paths through the use of diverters (see, for example, U.S. Patent Nos. 4,822,2.14 (Aidlin et al.), 4,938,636 (Aidlin et al.), 5,246,097 (McCoy et al . ) , and 5,501,552 (Simkowski) ) , and that displaceable arms can be pivoted to divert articles between single and multiple lines (see, for example, U.S. Patent No. 5,567,091 (Johnson et al.) and EPO Publication 0 668 223 (Steinle) where air is utilized to urge the articles through the displaceable arm, U.S. Patent Nos. 3,822,006 (Shuttleworth) and 5,174,430 (Ebira) where belts are utilized to convey the articles through the displaceable arm, and U.S. Patent No. 5,842,818 (Simkowski) where gripping fingers are utilized to convey the articles through the displaceable arm) . Summary of the Invention This invention provides an unstable article conveying device, particularly for unstable articles having a neck portion with a neck ring thereon, with the device including an article (or article line) diverter. The unstable articles are conveyed along a first path (preferably in single line, or file) established by a first guide unit to a plurality of second paths (each preferably also conveying the articles in single line, or file) established by a plurality of second guide units through a third path established by a third guide unit having a diverter with a first portion establishing a first end portion path of the third path that is aligned with the first path established by the first guide unit, a second portion establishing a second end portion path of the third path with the second portion being movable to align the second end portion path with different ones of the plural second paths established by the plurality of second guide units, and a flexible portion (preferably including a flexible bar) establishing a deviation in the third path upon aligning movement of the second portion. Aligning movement of the second portion of the diverter of the third guide unit, normally in opposite arcuate directions, is controlled by a controller (preferably acting in conjunction with a movable portion of a support bar of the diverter) to align the second end portion of the third path with different ones (preferably successive adjacent ones) of the second paths established by the plurality of second guide units. An article actuator, with article engagable members, is provided within an actuator path at each actuator guide of each guide unit, with each article actuator preferably being a movable chain within a chain (actuator) path and having flanges extending therefrom to engage the articles in the article path adjacent to the chain path. An actuator guide of each guide unit is also preferably positioned at opposite sides of each article path, to engage the articles and urge the articles along the article path upon movement of the article actuators along the actuator paths. It is therefore an object of this invention to provide improved article conveying. It is another object of this invention to provide improved article conveying for unstable articles having a neck portion with a neck ring thereon. It is another object of this invention to provide improved unstable article conveying utilizing article diverting. It is another object of this invention to provide improved article diverting for conveying of unstable articles between a single line, or path, and multiple lines, or paths. It is another object of this invention to provide an improved unstable article conveying device and method with article, or line, diverting for conveying unstable articles between a single line, or path, and multiple lines, or paths. It is another object of this invention to provide an improved unstable article conveying device that includes a movable diverter with a flexible portion that causes a deviation in the article path at the diverter upon movement of the diverter to align a single line and different ones of multiple lines. It is another object of this invention to provide an improved unstable article conveyor that includes a movable diverter with a flexible portion connected with a support bar having a movable portion and a controller for controlling movement of the movable portion of the support bar to cause movement of the diverter to align a single line and different ones of multiple lines with the aligning movement of the diverter also causing the flexible portion of the diverter to establish a deviation ■ in the article path at the diverter. It is another object of this invention to provide an improved unstable article conveyor that includes a first guide unit establishing a first path for the unstable articles and having article actuation associated with the first portion for urging the unstable articles along the first path, a plurality of second guide units each establishing a second path for the unstable articles and having article actuation associated with each of the plural second paths for urging the unstable articles along the plural second paths, and a third guide unit establishing a third path with the third guide unit having a diverter with article actuation associated with the third path for urging the articles along the third path and with a first portion of the diverter establishing a first end portion path of the third path aligned with the first path established by the first guide unit, a second portion establishing a second end portion path of the third path with the second portion being movable to align the second end portion with different ones of the plural second paths established by the plurality of second guide units, and a flexible portion establishing a deviation in the third path upon aligning movement of the second portion to align the second end portion with different ones of the second paths. With these and other objects in view, which will become apparent to one skilled in the art as the description proceeds, this invention resides in the novel construction, combination, arrangement of parts, and method substantially as hereinafter described, and more particularly defined by the appended claims, it being understood that changes in the precise embodiments of the herein disclosed invention are meant to be included as come within the scope of the claims.

Description of the Invention Articles 12 to be conveyed, or transferred, by device 13 of this invention are normally lightweight unstable articles, such as plastic containers or bottles, and such containers or bottles may have a neck portion 14 with a neck ring 15 thereon, as has been indicated in the drawings. It is meant to be realized, however, that other lightweight articles, and particularly lightweight unstable articles, could, at least for some applications, also be conveyed, or transferred, by the device of, and in accordance with, this invention. As best shown in FIGURE 1, unstable articles 12 are conveyed into device 13, normally in single file, and are received at device 13 on first article path 16 established by first guide unit 17. The unstable articles received on first article path 16 are conveyed to different ones of plural, or multiple, second article paths 18, established by a plurality of second guide units 19, through third article path 20, also normally in single file, established at movable guide, or diverter, 21 of third guide unit 22. Diverter 21, as best shown in FIGURES 2A, 2B, 3A and 3B, with straight line operation illustrated, has first portion 23 establishing first end portion path 24 of third article path 20 (aligned with first article path 16 as illustrated in Figure 1) , second portion 25 establishing second end portion path 26 of third article path 20 (with second portion 25 being movable to align second end portion path 26 with different ones of plural second article paths 18 (as illustrated in FIGURE 1) , and flexible portion 27 establishing divertable, or displaceable, portion path 28 of third article path 20 with flexible portion 27 being flexed upon aligning movement of second portion 25 causing a deviation in divertible portion path 28 of third article path 20 to align second end portion path 26 of third article path 20 with different ones of plural second article paths 18. While three second guide units 19 have been illustrated in FIGURE 1, it is to be realized that the configuration and/or number is meant to be an illustrative example, and any plural number, as needed or desired, could normally be utilized. The guide units (i.e., first, second, and third guide units 17, 19, and 22) are mounted on frame 29, and each guide unit includes at least one actuator unit 30, and preferably includes a pair of actuator guides 30 and 31, with the guides of each pair positioned at opposite sides of an associated article path (i.e., one of article paths 16, 18, and 20) established therebetween and extending lengthwise between the guides (with the guides thus being spaced from one another a sufficient distance to enable the articles to be conveyed along the article path established between the guides) . This arrangement is best illustrated in FIGURES 2A, 2B, 4, and 5 for diverter 21 of third guide unit 22, and a similar arrangement is preferably also utilized with respect to the first and second guide units (but normally with no provision for flexing to establish a deviation, or bend, in the article path as is provided in article path 20) , although the articles may, at least for some applications, be air conveyed through the first and second guide units in a manner such as taught in my U.S. Patent No. 5,842,818 (Simkowski). Each of the pair of actuator guides 30 and 31 includes an article drive arrangement 32, now preferably a mechanical drive arrangement, with each mechanical drive arrangement, or unit, including, as best illustrated in FIGURES 4 through 7, a driven chain 33 having a plurality of links 34 with flanges 35 that extend from the chain to the article path associated with the actuator guide having the chain in actuator, or chain, path 36 to engage and urge article movement of articles then on the article path by movement of the chain along the lengthwise extending actuator path 36. It is also meant to be realized that, while not now preferred, a single drive arrangement might, for some applications (and as generally illustrated in FIGURE 8) , be utilized at one side of the article path with a flange, ledge, or the like, utilized, for example, at the other side of the article to provide article support and/or that drive, or article actuation, might, for some applications, be utilized in addition, or in lieu of, the particular article drive arrangement described herein.. As best shown in FIGURES 4 and 5 and particularly described herein for conveyance of unstable articles 12 having neck portions 14 with neck rings 15 thereon, and using chain 33 with links 34 having flanges 35 extending therefrom to engage and urge the unstable articles along the associated article path, flanges 35 are preferably spaced from one another a sufficient distance to receive neck portions 14 (normally vertically extending as illustrated in the drawings) of unstable articles 12 therebetween and engage the bottom side of protruding neck rings 15 of the unstable articles to support the unstable articles and, due to frictional engagement between the articles and flanges, urge movement of the unstable articles along the article path established between the actuator guides and spaced flanges upon movement of chain 33 along chain path 36 (extending along and adjacent to the associated article path) in each of the actuator guides. Additional support for articles conveyed along the article paths, such as, for example, side support provided by flanges depending from the actuator guides at opposite sides of the article paths for engagement with the sides of the articles in the article paths, can also be utilized, as needed. Third guide unit 22 is adapted, by use of movable guide, or diverter, 21, to divert third article path 20, as necessary, upon movement of second portion 25 of the diverter to align first article path 16 with different ones of plural second article paths 18. More particularly, articles 12 conveyed along first article path 16 are received at first end portion path 24 of third article path 20, diverted as necessary in divertable portion path 28 of third article path 20, and conveyed from second end portion path 26 of third article path 20 to a then aligned one of plural second article paths 18. All of the guide units now preferably utilize the above-described chain drive for conveying the unstable articles through the guide units as set forth hereinafter with respect to third guide unit 22, with third guide unit 22 being also particularly adapted for article, or article line, diversion as set forth hereinafter. Major axis 37 of each link 34 of chain 33 extends in a direction normal (i.e., perpendicular) to the direction of chain path 36 established in each of the actuator guides 30 and 31. As best illustrated by FIGURES 6 and 7, when chain path 36 is horizontal, then major axis 37 of each link 34 extends vertically. This positioning of chain 33 is shown in FIGURE 4 and 5 to be effected in actuator guide 30 with actuator guide 30 substantially surrounding, or enclosing, chain 33. As best indicated in FIGURES 2A and 2B in conjunction with FIGURES 4 and 5, each guide unit 30 and 31 includes chain 33, preferably an endless chain that extends around sprockets 38 and 39 with sprocket 38 being rotatively driven by electric motor/gear box 40 to cause movement of each chain 33 along chain path 36. With use of a pair of actuator guides 30 and 31 positioned at opposite sides of an associated article path, separate endless chains 33 with flanges 35 extending therefrom are thus positioned at opposite sides of the associated article path (as generally indicated in FIGURE 9) so that flanges 35 engage articles at each side of the article path for urging movement of unstable articles then on the article path along the associated article path upon movement of chains 33 along chain paths 36. Each actuator guide has an elongated opening 41 that extends along the entire guide wall 42 facing the article path to enable flanges 35 to extend, from each link 34 of chain 33 in chain path 36 then within the guide, into the adjacent associated article path. As best shown in FIGURE 7, each link 34 of chain 33 has a pair of end plates, or ears, 43 and 44 that extend in a plane parallel to the direction of chain movement (i.e., horizontal when the direction of chain movement is horizontal) with end plates 43 and 44 being spaced from one another along major axis 37 of each link (i.e., vertically spaced when the direction of article movement is horizontal) , with apertures 45 therein to receive linking pins 46 (as indicated in FIGURE 6) between end plates 43 and 44, and with end plates 43 and 44 having contoured edge, or side, portions 47. Each chain link 34 also has a body portion 48 that includes a cylindrical portion 49 that extends in a direction normal to the direction of chain path 36 (i.e., extends vertically when chain path 36 extends horizontally) . End plates, or ears, 50 are at opposite ends of cylindrical portion 49 and extend in a plane normal to cylindrical portion 49 (i.e., are horizontally positioned when cylindrical portion 49 is vertically positioned) , with cylindrical portion 49 and end plates 50 having apertures 51 therethrough for receiving linking pin 52 (linking pin 52, as illustrated in FIGURE 6, is indicative of the linking pin needed to complete the endless chain and hence, when so used, becomes an additional linking pin 46) . End plates 50 also extend under end plates 43 and 44 for connection to end plates 43 and 44 thereat, with end plates 50 having edge, or side, portions 53 (i.e., vertically extending when end plates 50 are horizontally positioned) that are offset from end plates 43 and 44, and each link also having wall 54 extending between end plates 43 and 44 and cylindrical portion 49 at the side of the link from which flanges 35 extend for strengthening the link. As best shown in FIGURES 4 and 5, each flange 35 extends from the lower end portion (and therefore from end plate 43 and from the bottom of wall 54) of each link 34 in a direction normal to both chain path 36 and major axis 37 of each link 34 (i.e., each flange 35 extends horizontally from each chain link 34 and from wall 54 when chain path 36 extends horizontally) to engage articles then on the associated article path. As indicated in FIGURES 6 and 7, when links 34 are connected, or joined, by the linking pins to form endless chain 33, adjacent links have the cylindrical portion of one link received between end plates 43 and 44 of an adjacent link with contoured, or shaped, side edges 47 of each of end plates 43 and 44 of adjacent links, as well as side edges 53, adjacent to cylindrical portion 49 of adjacent links, permitting rotation of each link with respect to each adjacent link in the chain. With adjacent links joined to form an endless chain, flanges 35 of adjacent links extending into the associated article path are contiguous to one another, as indicated in FIGURES 8 and 9, to virtually form a moving continuous support for engaging articles then in the associated article path and urge the articles along the path upon movement of the endless chain to cause the flanges to be moved along the article path. As indicated in FIGURE 8 (illustrating a chain at one side of the article path) , during a straight run of the chain, flanges 33 extend substantially parallel with respect to one another into the article conveying path with substantially egual small spacing between adjacent edges 55 of each of the flanges. As indicated in FIGURE 9, angular deviations, or bends, in the associated article conveying path are enabled since adjacent links of the chains can be rotated with respect to one another to a degree sufficient to allow angular deviation of the chain path. As indicated, with chains utilized at opposite sides of the angular deviating section of the associated article path, flanges 35 at one side of the associated article conveying path are angularly deviated, or rotated, in one direction so that adjacent flanges have an increased spacing at the outer edges of adjacent flange edges 55, while flanges 35 at the opposite side of the associated article path are angularly deviated, or rotated, in the opposite direction so that adjacent flanges have a decreased spacing at the outer edges of adjacent flange edges 55. In a working embodiment of this invention, it has been found that a spacing of about 0.020 inches when parallel with a maximum increase and/or decrease in spacing of about 0.010 inches for turns results in about a permissible 24 inch turning radius. It has also been found in a working embodiment of this invention that use of dissimilar material for the chain and chain guide is preferred, with use of dissimilar polymer materials being now preferred, including, for example, Acetal for the chain and oil impregnated ultra high molecular weight (UHMW) polymer for the chain guide. To effect angular deviations, or bends, at divertible, or deviation, portion path 28 of third article path 20, flexible portion 27 of diverter 21 is flexed, or bent, at flexible portion 27. As best shown in FIGURES 2A, 2B, 10A, and 10B, third article path 20 is established at diverter 21 of third guide unit 22 between actuator guides 30 and 31, and flexible portion 27, preferably a vertically positioned flexible bar of metallic material such as aluminum or steel, of the diverter establishes divertible portion path 28 of the third article path between first and second end portion paths 24 and 26 of the third article path. First portion 23 of diverter 21 (establishing first end portion path 24 of article path 20 aligned with first article path 16) includes mounting plate 56 having a pair of drive mounts 57 mounted thereon. A sprocket 38 is rotatively mounted on each of drive mounts 57 and positioned to be at each side of the associated article path so that each sprocket 38 is driven by motor/gear box 40. Actuator guides 30 and 31, each having chain 33 in chain path 36, are mounted on mounting plate 56, spaced from one another, to form, or establish, first end portion path 24 of third article path 20 between the inner run of the chain in each actuator guide, inwardly of sprockets 38, with the outer side of each guide having a chain diverter 58 to divert the outer, or return, portion of the endless chain from sprockets 38 into the actuator guides. In addition, bracket 59 is also mounted on mounting plate 56 with bracket 59 extending upwardly from mounting plate 56 above actuator guides 30 and 31 for mounting of flexible bar 60 (inwardly of bracket 59) and one end of support bar 61 to bracket 59 (straps 62 are utilized to fasten the actuator guides to flexible bar 60 and support bar 61 at mounting plate 56) . Second portion 25 of diverter 21 (establishing second end portion path 26 of third article path 20 alignable with different ones of plural article paths 18) includes mounting plate 63 having a pair of sprocket mounts 64 mounted thereon (a sprocket 39 is rotatively mounted on each of sprocket mounts 64 and positioned to be at each side of the article path) . Actuator guides 30 and 31, having chains in chain . paths 36, are mounted on mounting plate 63 spaced from one another, and inwardly from sprockets 39, to form, or establish, second end portion path 26 of third article path 20 therebetween with the outer side of each guide having a chain diverter 65 to divert the outer, or return, portion of the endless chain from sprockets 39 into the guide. In addition, bracket 66 is also mounted on mounting plate 63 with bracket 66 extending upwardly from mounting plate 63 above actuator guides 30 and 31 for mounting of support bar 61 thereto (straps 67 are utilized to fasten the actuator guides to support bar 61 and mounting plate 63, with flexible bar 60 being received in flexible bar mount 68 (as best shown in FIGURE 4, flexible bar mount 68 is a plastic insert, or block, having an aperture therein slightly larger than the dimensions of the flexible bar to receive the flexible bar therein) between straps connected with different ones of the actuator guides so that the flexible bar is lengthwise movable along the straps (and hence relatively movable with respect to support bar 61 and mounting plate 63) . Support bar 61 has fixed end 69 connected to bracket 59 (connected with mounting plate 56 of first portion 23 of diverter 21) with bar 61 having a pivot 70 to enable movable, or pivotable, end 71 of bar 61 to move, or pivot, in opposite horizontal directions, with movable, or pivotable, end 71 being received at, and connected to bracket 66 (connected with mounting plate 63 of second portion 25 of diverter 21) . Flexible bar 60 extends lengthwise inwardly of brackets 59 and 66 of first and second portions 23 and 25 of line diverter 21 with one end of flexible bar 60 being slidably received between straps 67 to enable lengthwise movement of flexible bar 60 relative to straps 67 (for some applications, flexible bar 60 could be slidably received between straps 62 in lieu of being slidably received between straps 67) . Spaced sections 72 of actuator, or chain, guides 30 and 31 (with the spaced sections being preferably connected in pairs, as shown in FIGURES 1, 2A, 2B, 3A and 3B) are connected to flexible bar 60 by straps 73 at flexible portion 27 of diverter 21 with sufficient spacing between adjacent chain guide straps to enable flexing of flexible bar 60 (due to movement of second portion 25 of diverter 21 relative to first portion 23 of the diverter upon pivoting of pivotable end 71 of support bar 61 relative to fixed end 69 of the support bar) as necessary for path alignment between second end portion path 26 and different ones of plural second paths 18. As indicated in FIGURES 2A and 10A, sprockets 39 are mounted in lengthwise extending slots 74 on second portion 25 of diverter 21 to enable movement of each sprocket 39 in opposite directions along a path parallel to that of chain path 36 (and third article path 20) . As indicated in FIGURES 2A and 2B, with a straight third article path 20 through diverter 21, chain path 36 at each side of third article path 20 is preferably the same length, and sprockets 38 and 39 are spaced the same distance from one another. When a deviation occurs in third article path 20 by flexing of flexible portion 28 of the diverter, as is indicated in FIGURES 10A and 10B, this causes the chain path at the outer side of the deviation to' travel a distance greater than the distance traveled by the chain at the inner side of the diverter, and this requires that movable sprocket 39 at the outer side of the deviation be inwardly offset relative to movable sprocket 39 at the inner side of the deviation in order to maintain proper tensioning of the endless chains. This is accomplished by air cylinders 75, mounted on mounting plate 63 adjacent to each sprocket 39, to control lengthwise movement of each ω o o 13 H • o - SD ti ¬ OJ ti01 P ) 0> rt Φ •σ Φ ii CO p.

Positioning of diverter 21 for alignment of first end portion path 24 of third article path 20 with the different ones of plural article paths 18 nay be effected by controller 77. As is shown in FIGURE 1, controller 77 includes controller support 78 extending across second portion 25 of line diverter 21 with controller support 78 having carriage 79 slidably mounted thereon so that the carriage moves in reciprocal directions back and forth across control support 78. Carriage 79 is connected with support bar 61 by means of connecting arm 80 so that movement of carriage 79 causes angular displacement of pivotable end portion 70 of support bar 61 resulting in flexing of flexible bar 60 to cause an angular deviation to be established by the spaced sections 72 of actuator guides 30 and 31 at flexible portion 27 of diverter 21 and thus establish an angular deviation at divertable portion 28 of third article path 20. Carriage 79 is connected by connecting arm 81 with chain 82 mounted for rotation about sprockets 83 and 84 near the opposite ends of controller support 78, and sprocket 83 is rotatively driven by electric motor 85 to drive chain 82 and precisely position second portion 25 of line diverter 21 at a then selected one of the plurality of second guide units 19 to thereby align second end portion path 26 of third article path 20 with the then selected one of plural second article paths 18. Controller 77 could also be realized by other apparatus, such as, for example, through use of a screw drive arrangement, particularly where more precise positioning of the diverter is needed than is normally provided by a chain-carriage arrangement. As indicated in FIGURE 1, the plural second article paths 18 at the plurality of second guide units 19 are preferably adjacent to one another about an arcuate path at the ends thereof adjacent to second portion 25 of line diverter 21 to facilitate alignment with the second end portion path of the third article path, and may thereafter be brought toward substantially parallel relationship with one another. Second end portion 26 of third article path 20 is preferably successively and sequentially aligned with each adjacent one of plural second article paths 18 by repeated and/or additional flexing of flexible portion 27 of line diverter 21 as electric motor 85 causes second end portion path 26 to be moved in position from one second path 18 to the next adjacent path, preferably by movement in one arcuate direction until the outer plural second article path is reached, and then in the opposite arcuate direction until the opposite outer plural second article path is reached, with the alternate directions of displacement of the second end portion path being continued so long as normal operation is continued. An article counter 86 (indicated in FIGURE 2A as a spaced eye and receptor positioned to count articles passing therebetween) is positioned adjacent to second end portion path 26 of line diverter 21 to count the number of unstable articles passed from second end portion path 26 of article path 20 to plural second article paths 18 so that each time that a predetermined count is reached, article counter 86 can cause actuation, or energization, of electric motor 85 to shift delivery of unstable articles from a then selected one of the plural second article paths to an adjacent one of the plural second article paths. While a specific controller has been described herein for controlling line diverting, it is meant to be realized that control of line diverting, other than as above described, could also be utilized. In addition, it is also to be realized that the unstable articles are normally discharged from the second guide units for further conveyance, such as, for example, for conveyance to a palletizer for palletizing the unstable articles, and it is also meant to be realized that the direction of article flow could be reversed to transfer the unstable articles from the plural second paths to the first path through the third path, and that such transfer could, for, example, be used in connection with depalletizing of unstable articles. As can be appreciated from the foregoing, this invention provides an improved conveying system using article, or line, diverting for conveying unstable articles and, particularly, for conveying unstable articles, such as plastic bottles or containers, having a neck ring, between a single path, or line, and multiple paths, or lines.

Claims: WHAT IS CLAIMED IS: 1. A device for conveying unstable articles, said device comprising: a first guide unit establishing a first path for the unstable articles and having article actuation associated with said first path for urging the unstable articles along said first path; a plurality of second guide units establishing plural second paths for the unstable articles and having article actuation associated with each of said plural second paths for urging the unstable articles along said plural second paths ; a third guide unit establishing a third path for the unstable articles with said third guide unit having a movable article diverter with article actuation associated with said third path for urging the unstable articles along said third path, said article diverter having a first portion establishing a first end portion path of said third path aligned with said first path, a second portion establishing a second end portion path of said third path with said second portion being movable to align said second end portion path with different ones of said plural second paths, and a flexible portion establishing a deviation in said third path upon said aligning movement of said second portion; and a controller for controlling movement of said second portion of said article diverter to align said second end portion path with said different ones of said plural second paths. 2. The device of claim 1 wherein said paths for the unstable articles are established by said guide units such that the unstable articles are conveyed along said paths in single line. 3. The device of claim 1 wherein said article actuation at each of said guide units includes at least one article actuator and an actuator guide for establishing an actuator path extending along and adjacent to said associated article path with said actuator guide d Hi 3 OJ OJ 3 OJ cn 0 cn Q- Ω o 3 Ω n cn 13 3 cn o 13 Q 0- cr o ro Ω cr 13 <τi μ- OJ 3 Φ cn Ω 0 ii OJ Hi OJ μ- OJ Hi 0 0 ro d 0 0 Φ Hi 0 ) d μ- ► Hi 3 o 0 ) 0 0 3 rt cn OJ Ω cn ft < ti- μ- μ- <! d < 3 Ω •ϋ ii < Ω rt- μ- < OJ 3 < hi .
