The applicator means is operable to execute both a downward and forward motion to the sleeve such that the forward motion of the sleeve substantially is synchronized with that of the article during fitment of the sleeve thereto.
Description
- This invention relates to an applicator mechanism for fitting an end closure sleeve onto one or more articles in a multiple packaging process. The applicator mechanism is particularly useful for fitting a sleeve onto a pair of bottles at each end of a group of bottles which then has an open-ended wrapper applied thereto which holds together the bottle group to form a multiple unit package. The wrapper has its opposite ends closed by the fitted sleeves thereby forming a totally enclosed package which is suitable for protecting bottled beverages whose organoleptic properties can be affected by ultra-violet light. Such a package is disclosed in our U.S. Patent Application Serial No. filed July 29, 1982 entitled "Article Carrier."
- One aspect of the invention provides a mechanism for applying a sleeve to at least one moving article so that the article is introduced through an open base of the sleeve, which apparatus comprises supply means for accommodating a plurality of said sleeves in collapsed condition, erecting means to bring each sleeve sequentially into a set-up condition and present the set-up sleeve for downward transfer towards the article to be sleeved, transfer means to effect said downward transfer and applicator means for fitting said transferred sleeve around said article, said applicator means being operable to execute both a downward and a forward motion to the sleeve such that the forward motion of the sleeve is substantially synchronized with that of the article, conveyed beneath the mechanism, during fitment of the sleeve onto said article.
- Another aspect of the invention provides a method of applying a sleeve to at least one moving article so that the article is introduced through an open base of the sleeve, which method comprises withdrawing a collapsed sleeve from a supply and bringing the sleeve into a set-up condition, transferring the set-up sleeve towards the article to be sleeved, executing a downward and forward motion to the sleeve to complete the transfer step so that the sleeve is fitted around said moving article and such that the forward motion of the sleeve substantially is synchronized with that of the article during fitment of the sleeve thereto.
- An embodiment of the invention will now be described, by way of example, with reference to the accompanying drawings, in which:-
- Figure 1 is a perspective view of a closure sleeve suitable for use in the mechanism according to the invention,
- Figure 2 is a perspective view of a completed package incorporating a closure sleeve at each of its ends,
- Figure 3 is a schematic side view of the applicator mechanism according to the invention.
- Figure 3a is a schematic perspective view of the main gear trains incorporated in the applicator mechanism;
- Figure 4 is a schematic end view of the applicator mechanism according to the invention, and
- Figures 5 to 7 are schematic views illustrating fitment of a sleeve around a pair of bottles.
- Referring first to Figure 1, there is shown a
closure sleeve 10 suitable for use with the mechanism according to the invention. Thesleeve 10 comprises aamin panel 12 to the top edge of which anauxiliary panel 14 is hinged alongfold line 16.Auxiliary panel 14 is cut away at each end and thefold line 16 stops short of each top end edge of the main panel leaving exposedshoulder portions Side panel 22 is hinged to one side edge of the main panel alongfold line 24 and, similarly,composite side panel 26 is hinged to the opposite side edge of the main panel alongfold line 28. Aback panel 30 is hinged to each of the side panels alongfold lines nesting notch 30a is formed in the upper edge of the back panel. Thus, economy of material is achieved since the closure sleeve can be nested with an adjacent closure sleeve by means of cooperation betweenauxiliary panel 14 of one blank and nestingnotch 30a of an adjoining blank. - A completed
package 36 is shown in Figure 2 in which a group of bottles 'B' are accommodated within an open-ended wrapper 38 havingend closure sleeves 10 at each end thereof. Each end closure sleeve encloses an endmost pair of bottles within the package and theauxiliary panel 14 is folded inwardly of the package alongfold line 16.End panel 38a of the wrapper is folded downwardly in overlapping face contacting relationship with the outer face of the adjacentauxiliary panel 14. - An applicator mechanism for applying a closure sleeve such as that shown in Figure 1, to a pair of bottles is illustrated in Figures 3, 3a and 4.
- Referring to Figure 3, the applicator mechanism comprises two
similar units wrapper 36 shown in Fig 2, to a group of bottles. - As shown in Figures 3, 3a and 4, the
applicator mechanism 40 comprises ahopper 44 in which a supply ofclosure sleeves 10 are held each with its main andauxiliary panels open mouth 46 of the hopper. The hopper is mounted in an inclined attitude above asleeve guide 48 comprisingguide plates hopper mouth 46 is disposed adjacent the path of movement of a sleeve withdrawal device 'WD'. The withdrawal device comprises anoscillatory arm 50 fixedly mounted on arotary shaft 52 which is journalled at each of its ends inbearings vertical face plates mechanism 40. Thearm 50 carries at its free end a pair ofvacuum cups 62 for engagement with the main panel of the leading sleeve within thehopper 44. A connectinglinkage 64 is pivotally mounted at 64a to thearm 50 intermediate its ends and to acam 66 carried byrotatable shaft 68 mounted parallel to and aboveshaft 52. Shaft 68 carries a drivensprocket 70 which is rotated throughchain drive 72 and sprocket 74 mounted onshaft 76.Shaft 76 also is journalled in bearings carried by thevertical face plates rotary shaft 52 to be driven fromsprocket 78. Sprocket 78 is driven bychain 79 which also is entrained aboutsprocket 78a carried byshaft 76a ofapplicator unit 42. Shaft 76a is driven by chain andsprocket drive shafts rotary shaft 68 which causes the oscillatory arm to pivot through a predetermined arc by virtue of the connectinglinkage 64 so that itsvacuum cups 62 oscillate towards and away from themouth 46 of the supply hopper. - When the
vacuum cups 62 are in abutment with themain panel 12 of the leadingsleeve 10 present at the mouth of the hopper, vacuum is applied so that the sleeve is engaged and as theoscillatory arm 50 is pivoted away from the hopper mouth, thesleeve 10 is brought into a set up condition as shown in Figure 3 abovesleeve guide 48. In this position themain panel 12 of thesleeve 10 is held adjacent theforward guide plate 48b. Suction is then released so that thevacuum cups 62 are detached from thesleeve 10 whereafter the sleeve may be transferred downwardly through thesleeve guide 48 for fitment over a pair of bottles 'B'. - A series of bottles 'B' are conveyed in pairs along
conveyor base 80 by means ofside lugs side lug chains guide 48. - Transfer is effected by means of a pair of spaced
vertical transfer chains sprockets Sprockets vertical face plates oscillatory arm 50 andsprockets rotatable shaft 76. Each of thetransfer chains sleeve 10 to effect transfer thereof through thesleeve guide 48. - The lugs 102,104 engage the upper edge of each of the
side panels sleeve 10 and push the sleeve downwardly through theguide 48 towards a pair of bottles present onconveyor base 80 adjacent the lower end ofguide 48, and on which the sleeve is to be fitted. As the open base of the sleeve approaches the tops of the bottles cam elements 106,108 carried by rotatable cam discs 110,112, respectively, pass through theshoulder portions side panels cam discs rotatable sleeve 85 concentric withshaft 76 and are disposed inwardly ofsprockets sleeve 85 is driven fromshaft 76 through a suitable chain and sprocket train. Referring more specifically to Figure 3a, the train incorporatessprocket 87 mounted onshaft 76 which drives, viachain 89sprocket 91 mounted onshaft 93. Shaft 93 also carries sprocket 95 which in turn drives, viachain 97, a sprocket 99 mounted jon thesleeve 85. Tie input to output ratio of this chain and sprocket train is chosen such thatcam discs kets - The
cam elements respective sprockets - Figures 5 to 7 schematically illustrate the cooperation between the transfer lugs and the cam elements during seating of a sleeve onto a pair of bottles. Reference is made to transfer
lugs 104 andcam element 108 carried bycam disc 112 acting on one side ofsleeve 10, it being understood that the opposed components comprisingtransfer lugs 102 andcam element 106 carried bycam disc 110 act on the other side of the sleeve in like manner. - When
sleeve 10 has moved through thesleeve guide 48 to the position shown in Figure 5, in which the open lower end of the sleeve is disposed immediately above the bottle pair 'B', downward pressure is being exerted bytransfer lug 104 on the top edge of one side wall of the sleeve. At this time,cam element 108, carried bycam disc 112, also engages the top edge of the side wall. Thecam element 108 is then at a position approximately 10° above the diametric datum line 'X-X'. Transfer of the sleeve then continues with force applied for a predetermined period simultaneously by both thelug 104 andcam element 108. When the sleeve has been moved downwardly to the position shown in Figure 6, downward force is continued solely by thecam element 108. This occurs since the arcuate speed ofcam element 108 is greater than that oflug 104 passing aroundsprocket 98. At thistime cam element 108 is approximately 10° below diametric line 'X-X'. - As the cam element continues along its arcuate path the sleeve is forced downwardly and forwardly during fitment onto the bottle pair 'B1'. The
cam element 108 continues its arcuate movement wiping across the top edge of the side wall of the sleeve so as to execute a forward accelerating force on the sleeve to bring the forward speed of the sleeve into synchronism with that of the bottle pair to which it is applied. - In Figure 7 the cam element has completed execution of the wiping operation whereby the sleeve is seated on the bottle pair 'B'. Once the sleeve is seated, lug 104 passes over the top edge of the sleeve behing the cam element to continue on its return run towards
sprocket 100 - The sleeved bottles then proceed along
conveyor base 80 to a wrapping station of the machine (not`shown). - The
applicator unit 42 is similar in construction tounit 40 and like reference numerals disignate parts with the addition of suffix 'a'. However, inunit 42 thesleeves 10 are accommodated within hopper 42a such that the main panel andauxiliary panel guide plate 48a' so that theback panel 30 of the sleeve is located adjacent the mouth of the hopper. This arrangement is required since it is required to fit one sleeve at each end of a package so that both sleeves of the package have their main panels facing outwardly. The arrangement and timing of operation ofunit 42 is such that the bottles sleeved byunit 40 pass beneathunit 42 together with a preselected numver of unsleeved bottles pairs until the required pair of bottles to be sleeved byunit 42 is positioned for sleeving. Thus, the bottles sleeved byunit 40 form one end of the package whilst the bottles sleeved byunit 42 form the other end of the package.
