INVENTOR Irving D. Glazer ATTORNEYS BOTTLE CARRIER STRIPPING APPARATUS Irving D. GlazenDailas, Tex., assignor to Dara Pal: Corporation, Dallas, Tex., a corporation of Texas Application May 13, 1957, Serial No. 653,835 18 Claims. or. 214 310 be suspended therefrom b'y'relative longitudinal and transverse movement betweenthe carrier and bottles whereby said carrier is quickly and economically removed.
A particular object of the invention is to provide an iniproved bottle carrier stripping apparatus, of the character described, havin'g'means for feeding a case ofbottles and their associated or connected carriers to stationary means for lifting the carriers while holding the bottles against upward displacement whereby said bottles are separated from said carriers for movement with the case upon the feeding of a following case.
An important object of the invention is toprovide an improved bottle carrier stripping apparatus, of the character described, having reciprocal feed means arranged to engage one case of bottles at a time for advancing the same beneath a stationary stripper and being disengaged from the stripped case for engaging and advancing a following case whereby the'car'tie'rs are stripped automatical- 1y frorn'tli'e'bottles'. 7 r 7 A construction designed to carry out the invention will be hereinafter described, together with other features of the invention.
The'invention will bemore readily understood from a reading of the following specification and by reference to the accompanying drawings, wherein an exampleof the invention is shown, and wherein:

The 1 lower ends of the posts 16 extend through the cross bars 17 externally of the frame members and are screwthreaded for receiving nuts 18 above and below said bars to permit adjustment of the elevation of the platform 15'. A horizontal base plate 19 is supported by the cross bars so as to underlie the platform between the posts. For guiding a case A of bottles B beneath the platform, a pair of substantially coextensive angle bars or rails 20 are carried by stanchions 21 upstandingfrom the frame members 11. The guide rails 20 are disposed inwardly of the posts immediately above the base plate U and have outwardlyflaring end portions 22tat the opposite or left-hand end of theframe 10. V
The bottles B are of the usual type having reduced neck portions N and are adapted to be suspended from a platelike bottle carrier C havingflexible jaws J for gripping the neck portions (Fig. 3'). Each carrier C is arranged tosupport a plurality of bottles B, usually six, and groups of earner-connected bottles, usually four, are mounted inthe case A for ease in handling. Due to thefiexible jaws J, the carriers may be stripped from the neck portions N by relative movement longitudinally of the bottles. As will be'explained, bottled-filled cases are adapted to be advanced endwise' beneath the platform 15 of the stripper 14 for lifting and separating the carriers from the bottles. A longitudinal extension or continuation 23 projects from the left-hand end of the platform beyond the posts 16 and has a plurality of longitudinal guide bars or members 24 depending from its underside in parallel, spaced relationship for receiving the bottles therebetween. As shown in Fig. 2, the guide bars 24 extend beneath the platform and may be coextensive therewith for reinforcing the extension 23. The left-hand ends of the guide bars project from the extension and terminate in elongated stripper elements or fingers 25 which have downwardly and outwardly inclined upper surfaces 26 for engaging the undersides of the bottle carriers between the bottles and at the longitudinal margins of said carriers.
Substantially coextensive holddown ribs or members 27 and 28 are carried by the undersides of the guide bars 24 and stripper fingers 25 for engaging the enlarged lower portions of the bottles B upon "engagement of the surfaces 261 of said fingers withthe undersidesof the carriers C (Fig. 4). The ribs 27 of the outer bars and fingers are substantially L-shaped and directed inwardly, while the ribs 28 of the inner bars and fingers are V-shaped for engaging bottles on both sides thereof (Fig. 5). Due to this arrangement, the bottles are confined against displacement upon advancement through the stripper 14. Since the inclined surfaces of the stripper fingers engage their undersides, the carriers are lifted'or pried from'the neck portions of the bottles upon such advancement. 'It is noted that the adjustable mounting of the platform 15 permits the stripper to accommodate bottles of diiferentheights. Although not shown, any suitable means may be provided for receiving the stripped carriers. i v,
For conveying or supporting the bottle-filled cases A, an angle bar 29 overlies and extends longitudinally of each fr'amemember 11 below the guide rail 20 and has its lower, horizontal flange directed outwardly and interposed between said frame member and the stanchions 21. The inner, upright flange of each angle bar 29' carries apluralityof'narrow'conveyor rollers 30whichai rollers extend from the left-hand end of the frame to the left-hand cross bar 17 so as to underlie the platform extension 23 of the stripper 14. As a result, the advancing cases ride from the rollers and slide over the cross bars and base plate. Although not shown, any suitable conveyor means may be connected to the righthand end of the frame for receiving the cases.
An upright pusher element or plate 31 is mounted for V reciprocation between the angle bars 29 and is adapted to engage the left-hand end of a case A for advancing the same through the stripper 14. The pusher plate 31 has a pair of .upstanding arms 32 and is carried by the outer end of a piston rod 33. Preferably, the pusher plate is adjustably connected to the rod 33 by nuts 34 screw-threaded on said rod. For reciprocating the rod and pusher plate, an air or other pressure fluid cylinder 35 is suspended beneath the frame 10. As shown most clearly in Fig. 6, the right-hand end of the cylinder 35 is pivotally connected to the underside of the right-hand end member 12 by a suitable bracket 36. This pivotal mounting permits the cylinder to swing about a horizontal axis relative to the frame so as to accommodate vertical movement of .the pusher plate. A flanged roller 37 is mounted on each side of the pusher plate, being journaled upon a transverse pin 38 having a nut 39 screw-threaded on its inner end (Fig. 7). To facilitate mounting of the roller 37, an opening 40 may be formed in the pusher plate.
A pair of upper tracks 41 extend longitudinally of the frame inwardly of the angle bars 29 and rollers 30 for receiving the rollers 37 and supporting the pusher plate 31 between said angle bars and in position for engagement with the end of a case A. The track 41 is of less length than the angle bars so as to terminate short of the ends thereof and has pivoted 'end portions or switches 42 and 43. A spring 44 is connected to the inner end of each switch 43, which has an intermediate pivot, for maintaining the switch in alinement with its track and permitting clockwise tilting of said switch. Counterclockwise tilting of this switch from its alined position is prevented by an adjustable stop 45 underlying its inner end. The left-hand switches 42 are pivoted at their inner ends and hang downwardly from the tracks. A pair of lower tracks 46 underlie the upper tracks 41 and have upwardly inclined end portions 47 and 48 which terminate in horizontal portions 49 and 50 beyond and below the switches 42 and 43. The inclined track portions 47 and 48 underlie the switches and, when said switches pivot downwardly, their outer ends rest on said inclined portions. A pair of longitudinal mounting plates 51 are provided for supporting the tracks, switches and associated elements and are connected to the frame members 11 by transverse braces 62. It is noted that the left-hand end of the cylinder 35 is supported by the engagement of the rollers with the tracks whereby a weight is provided for holding said rollers engaged with said tracks.
As shown in Fig. 4, the upper tracks 41 support the pusher plate 31 in position for engagement with the end of a case A and the case is advanced through the stripper 14 upon reciprocation of said plate toward the right. When the rollers 37 pass the intermediate pivots of the switches 43, said switches are swung clockwise into engagement with the underlying inclined track portions 48 to permit said rollers to ride onto the track portions 50. The force of the springs 44 immediately return the switches to their alined or horizontal position whereby the inclined track portions are cleared for receiving the rollers. It is noted that the intermediate pivots of the switches 43 are in substantially vertical alinement with the ends of the stripper fingers 25 so that said switches do not pivot clockwise until the carriers C have been stripped from the bottles B. Also, the track portions 50 support the pusher plate at suflicient elevation to engage the case.
Upon reciprocation of the pusher plate to the left by the rod 33, the rollers 37 ride down the inclined portions 48 beneath the switches 43, along the tracks 46 and up the inclined portions 47. It is noted that the pusher element passes beneath the cases due to the spacing between the tracks 41 and 46 (Figs. 2 and 5). Since the switches 42 are pivoted at their inner ends, the same are swung upwardly by the rollers to permit said rollers to ride onto the horizontal track portions 49. As shown in Fig. 8, the cases C are continuously supplied to the stripping apparatus whereby said cases follow one another. As a result, the upwardly moving pusher element engages and tilts the case following the case to be stripped until it passes from therebeneath upon reciprocation to the right. Although the switches 42 swing downwardly when the rollers ride onto the track portions 49, said switches direct said rollers onto the tracks 41.
For automatically reversing the reciprocation of the pusher plate 31, an actuator 52 is carried by the lower end of said plate and projects from each side thereof for engaging bleeder or remote control valves 53 and 54 at the ends of the stroke. The valve 53 is suspended from the left-hand end member 12 by a transverse angle bar 55, while a suitable bracket 56 connects the valve 54 to the left-hand end of the cylinder 35 (Fig. 4). A main control valve 57 is connected to the bleeder valves by lines 58 and 59 and to the ends of the cylinder by lines 60 and 61 (Fig. 6). The valve 57 has a conventional inlet for receiving air or other fluid under pressure and a pair of exhaust outlets. With this arrangement, pressure fluid is exhausted from the right-hand end of the cylinder and supplied to its left-hand end when the actuator 52 engages the bleeder valve 53 at the end of the left or outer stroke so that the pusher plate is reciprocated inwardly or to the right toward the stripper 14. When the actuator engages the bleeder valve 54,
pressure fluid is supplied to the left-hand end of the cylinder and exhausted from its right-hand end whereby the pusher plate is reciprocated outwardly or to the left away from the stripper.
The foregoing description of the invention is explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated construction may be made, within the scope of the appended claims, without departing from the spirit of the invention.
