Abstract

ADJUSTABLE GLUE APPLICATOR ROLLS
FOR CONTAINER LABELING MACHINE

Abstract of the Disclosure Peripherally contacting applicator and fountain rolls of a glue pot are mounted on individual pivots and are journaled on support yokes which are swingable toward and away from con-veyed containers on a linear path adjacent to one side of the glue pot. The swinging of the two yokes and their supported applicator and fountain rolls is under control of two independent screw adjustment shafts having swiveled connections with the glue pot and yokes. The arrangement enables the application of glue to containers with and without recessed label receiving surfaces.

Description

Lg7~

Prior art container labeling machines are known in which conveyed rolling containers, such as bottles pass through the labeling machine on a llnear path adjacent to glue applicator means in a horlzontal mode and an upright mode the prevent invention relates to improvements in the latter type ox machine where the containers move past the glue applicator roller in an upright guided rolling mode.
In the prior art, when labels mu9~ be applied to con-tainers having recessed and non-receæsed labeling sur~aces~
difficult and time-consuming adjustments of the glue pot struc-ture across the path of movement of the container and along such path generally mutt be made.
he main objective of the presank invention i8 to pro-vide a simpler and more economical and convenienb arrangement for adjusting the glue applicator and fountain rolls of a glue pot in relation to passing upright containers ox either mentioned type without the necessity or adjusting the entire glue pot structure at leaæt across the path of movement of the guided containers. The necessary ad~u~tment ox ths bwo rolls can be made much more conveniently and quickly without requirlng great skill. the adjusting means it self-locking in any selected adjusted position so that the rolls will not wander during operation of the maohine. The two rolls of the glue pot are independently adjustable and independently driven through gear which are coaxial with the pivot axes of the support yokes for the two rolls. This particular geometry ¢ontribube~ to the preoision action of the me¢hanism, Other features and advantages of the invention will become apparent to those skilled ln the art during the following desoription in which:

Figure 1 is a perspective view of the inventlon, Figure 2 it a plan vlew of the lnventio~ with the applicator and mountain rolls ad~ustad Jo apply glue to a container having a recessed labeling surface;
Figure 3 it a similar view with the two rolls adJusted to apply glue to a non-recessed container; and Figure 4 it a fragmentary vertical section taken on llne 4-4 of Figure 2.
Re~errlng to the drawings in detall whereln like num-erals designate like part, the numeral 10 designate a gluepot ad~ustably mounted ad~acenb to one side ox a horizontal con-veyor 11 for uprlght axis containers 12. These containers may have recessed label-receiving surfaces 13, Figures 1 and 2~ or non-recessed label-receiving surface 14, Figure 3. The ad-~ustable glue applicator roller means aocording bo bhs invention has the capability ox applying glue with preoi~ion Jo either type of container, A3 the conba~ners move through the gluing station, they are caused to roll continuouslg on bheir upright axes through contact with the moving belt 15 on their outer sides and en-gagement with a guide rail 16 on their inner sides relative to the glue pot 10, and parallel to the belt 15, this mode ox conveyance of the contalners it convenbional, A glue applicator roll 17 having an upright axis par-allel to the axes of the containers is ~ournaled on a rigld yoke 18 which in turn is pivokally connected with an uprlght axis drive shaft 19 carrying a drlve gear 20, The applicator roll 17 carrles a series of spaced parallel glue applicator ring 21J whose peripheries contaot the oontainer area 13 to apply axially spaoed annular stripes 22 of glue thereto as the 1~7~7~

container rollingly engage the properly adjusted applicator roll at the gluing station.
The drive shalt 19 is suitably driven by a means, not shown, underneath the glue pot lo The drive gear 20 t S in mesh with a driven gear 23 for the applicator roll 17 attached to the upright axis shark 24 of the applicator roll, A parallel axis ~ounta~n or supply roll 25 or glue is ~ournaled on a swlngable yoke 26 similar to the yoke 18 which i9 pivotally held on another upright axis drive sham 27 carry-ing a gear 28 meshing wibh a companion gear 29 atbached to the shaft 30 of mountain roll 25. The two roll 17 and 25 are thus independently gear driven and are continuously driven throughout the pull ranges ox pivotal adjustment of the yokes 18 and 26 due to the coaxial relationship ox the yoke pivots to the drive gear 20 and 28, The yokes 18 and 26 and their rolls 17 and 25 are independently preci~io~ adjustable around bhe axe ox shafts l9 and 27 by the operation of screw-ad~usti~g shafts 31 and 32 each having a turning handle 33. Each adjusting screw shalt has a swlveled support at 34 on a ledge 35 ox the glue pot 10.
Mach shalt 31 and 32 ha a slmilar swiveled connection at 36 with the lower arm 37 of each yoke 18 and 26. Mach s¢rew ad-rusting shalt includes a female element 38 and a male element 39J as shown, A lock nut 40 is provided on each adJusting shaft to secure the elements 38 and 39 and the respeotive rolls 17 and 25 in their selected adjusted positions with precls~on.
: It can be seen in Figure 2 that the rings 21 ox appli-cator roll 17 can be holy adJusted to rollingly engage the recessed surface 13 ox each passing container 12 whlle the fountain roll 25 is independently adjusted into contact with ~76~6 the peripherieæ of the rings 21 to transfer glue bhereto prom the glue pot. No adjustment ox the glue pox assembly 10 across the path ox travel ox the containers 12 is required, a necessi-tated by the prlor art When container3 without recessed labeling areas are being processed as shown in Figure 3, the two rolls 17 and 25 with their yokes 18 and 26 are appropriately adjusted by using the screw adjusting shafts 31 and 32 to back off the two rolls until they properly engage the label receLving surfaae 14 while maintaining contact with each other again without necessitating movement of the glue pot assembly 10 relative to bhe containers It should also be explained that each yoke 18 and 26 at its top has a pivot extension 19' and 27' coaxial with shafts 19 and 27. A yoke stabilizer 41 l provlded and has its vertlcal portion 42, Figure 1J attached to one side wall ox the glue pot 10. A top horizontal arm 43 of the yoke sbabilizer ha open-lngs pivotally receiving the extenslons 19' and 27', In lleu of the shafts 24 and 30 formlng plvokal oonnec-tions with the tops of yokes 18 and 26, suoh tops may be of rlng form to surround the tops of rolls 17 and 25 so as Jo form journals therefor.
The invention embodied in the described roller ad-~usbing meohanism is characberized by convenience, precision in operatlon and economy in accordance wibh the objectives of the invention.
It l to be undersbood that the Norm of the invention herewibh shown and described is to be waken a a preferred example of the same, and that various changes in the shape, size and arrangement ox parts may be resorbed to, without de-parting from the spirit of the inventlon or scope ox the sub-joined claims
