" application mea Ntvember as, 1929. serial' 110,426,566.

. To all whoml t may concern Be it known that I', J oHN VAN RUBEN, a citizen of the UnitedStates, and a resident of Brooklyn, in the county of Kings and State of New York, haveV invented certain new and useful ImprovementsI in Packagingv Machines, of which the following is a specification. i

The present invention relates in general to wrapping and packagingmachme's, and more particularly to machines for wrapping individual articles and then collecting them in. groups and finally wrapping such groups into packages, and has specialreference .to the provision ofj a -machine peculiarly adapted for wrapping sticks of so-called chewing 'gum and then assembling a .predetermined number of' such wrapped sticks and forming Atherefrom a 'commercial' package. n

uThe' machine divides itself broadly considered into two general parts, the first including the means and methods employed for wrapping the individual sticks, andthe to be wrapped;

second including the means and methods for collecting and,` wrapping a1 number of ,-the

sticks wrapped'by the first part of the ma.

chine. For convenience in illusfration and description, part of the machine 1s shown more fully in detail in co-pending compan- 1 ion application Serial No. 426,565 filed con#v The"J desired results above suggested includes in general groups of elements for performing the ollowing functions and operations;

1. Positioning asuitable prece-of wrapping paper made'of correct size as by cutting it from a roll; f i

2.' Feeding against the paper the yarticle currently herewith.

3. Causing the wrapping-paper to eni compass the article ,zincluding folding the f. 5. Causing the wrapped article andthercby fix the wrapper ends thereof; Y

4. Positioning a suitable label in the path of movement of the article and feeding the latter thereagainst;

label to/ encompass the in position; a 6. Assemblingthe wrapped and labelled articles into groups;

7 Positioningl a suitable I*piece of wrap'- 7 yping aper in ille path of movementxof the assem led group;

achine adapted for ,producing the 8. Feeding against the paper the as sembled group 9. Causing the wrapping paper closely to encompass the group, including .folding the ends' and sealing the wrapper as .an entirety in folded position;

. 10. Positioning .a suitable label in the path of movement of the wrapped and sealed package, and feeding the latter thereagainst;

11. Causing the .label to' encompass the wrapped and sealedpackage andhfix the Wrapper thereof in position; Y 12. Efecting the completed package the machine. i

The lprincipal objects-.of the present invention are an improved machine and method for producing an improved wrapping .and packaging of' articles of the charfrom acter referred to, and one which willv accomplish such functions and operations most economically, together with an improved package produced thereby, and `v`'such other ybenefits and advantages as may hereinafter appear. l

While machines containing the present invention have other fields of usefulness,- it is found particularly adapted for use in connection with articles of the general, shape andcharacter of sticks of chewing gum,

Figs.v 12,13 and 14 are elevations of the transfer mechanism showing its parts in dif-I ferent relative positions in order to illustrate theJ operation thereof.

As a matter of convenience in description, the several groups of elements will now be described according to the order followed in performing-the functions and operations hereinabove outlined.

Referring first to Figures 1 and 2 of the drawings, it will beobservcd that the indivi'dual sticks of gum. duly wrapped .and

` labeled in ividiially if desired. as described in -oo -pend Iig companion application Serial No. `426,565, may 'be fed from the carrier 127 by the fingers 86 on the chains 85 through t-h s106147 to an asscmblingmcchanism now,` obe described. y

Referring to` Figures .12 to 1l it. may be 'seen' that t-he guide is curved downwardly 'and thatone of its walls' extends below the other. Platform members 154' are held 'against the-extended. wall by springs 154;

' Y whichl provide a resilient support. for the platform. Backing members 155 are spring pressedl into contact with the other wall of 'guide 147 and these when' inthe position-in which they are shown in Figure i12` form continuations of the guide. A stop 156, .piv- 'oted at 156 isjheld bya spring across .the guide1-l7 (F ig 14). 157 designates the arms of a reciprocatory' shifting device, pivoted at 15S and loscillated byfaflink 159 pivoted to a yoke 160 actuated bya'n -eccentric (not shown).

A stream of the wrapped gumstieksC is fed through :the guide 147 'by the spaced l pairs bfngers 86 on the cha-ins85, past the i .s topl156 onto the platform members 154. As gum. stick approaches hthe'. platform' 55 members, itcrowds the stop156 downwardeac ly about its pivot 156 intov the position in `which it is shown in Figure 12. Should a stick ofgumoverrun the feeding fingers 86.

it will. lbe arrested 'by the stop 156 and held. there luntil lthe fingers 86 catch up with 'it past the stop-to the platformand force; it members.' Y.

#As the gum stick reaelfes the platform members`.'the arms 157 f move to the left to .the :position shown'in Figurell, to shift itV A. against the backing members 155 and out of 1 Lamas? the'way ofthe next stick of gum to pass through the guide 147. Or if more than one .stick of gum is on the platform at the time,

all of theml'and the backing member will be shifted, three sticks ofgn'm being' shown in Flgure 13. This will permit the stop 156 Ito rise as shown in Figurev13 until theshift- .guide 252. The chains aredrivcn at an ir regular rate by cllipticalgearing which will vbe described hereinafter which is so proportioned und arranged that the fingers 163 will pass the platform members 154 at a comparati\-'el "high rate of' speed.

The continued movement of these fingers 168 :is the chains 162 are driven by the sprocket. wheels 164 fccds the predetermined number of gum sticks from the platform 151 against waxed paper fed downwardly b v rollers l165. 166 into thcypath of the feed ofthe assembled `:rroup for the packaging operation.

Referring now to/Fign'rc's A1, 2 and 3, a strip of paper (l from a, roll (not shown),

preferably parafiined paper. is fed down- 1 wardly topositioning and cuttingoff mech# anlsm shortly to be descrlbed.`

Reverfing particularlv to VFigure 2, the

.paper strip'G'is fedbctween rolls 200, 201.r

the lat-tcr'of which is continuously ,driven by means of :tchaiu 202 running over a sprocket 203 fixed to the shaft 201 upon which-the/roll 2011's mounted. The chain 202 is driven b 'v a sprocket. 205. (Figures 1 and 3). fixed on the shaft 206 cai-lying the gear 207 meshing with the gear 20S en thc stnb-shuft 209 having-agear 210 in mesh with and driven by the gear 211 on the line shaft 169 driven from a convenient source of iower not shown). 'lo assure that the -ro s 200. 201 movecin unison. they are pro- Ivided with intermcshing gears 212. 213.

Positioned hclow-' therolls 200, 201 are the feed rolls 165, 166 carried by shafts 214, 215 provided with intermeshing gears one of Awhich is indicated at 216 in Figure 3.

The shaft 214 carrying the roll 165 is driven with-'a step-by-step movement through the v pinion 217 in mesh .with the gear 216 on the stub-shaft 219. the gear 218 being 1n mesh with the gear 220 fixed to the shaft 221.

For imparting intermittent movement to l the shaft-221 there is mounted thereupon a'` star-wheel 222 driven by a pin 223,(F1gure 6), on a. crank 224 .mounted on a shaft 225 which in turn is driven by the elliptical gear 226 in mesh with another elliptical gear 227 on the shaft 206 above referred to.

By this combination .of' a Geneva starwheel movement and the pair of double elliptical gears described, lthere is attained a quick initial movement of the shaft 221 and a slow stop thereof, which is of peculiar utility for certain purposes to be hereinafter pointed out.

As a result of the continuous movement o rolls 200, 201 and the intermittent movement of the rolls 165, 166 a slack ini the paper strip G is intermittently produced between the two pairs of rolls, the purpose of which will presently appear.

Reverting to Figure 3, it will'beseen that the pressing rollers 200 and 166 are rotatably carried in pairs-of upper and lower yoke members 228,229 which in turn are pivoted upon a shaft 230 and are held in vieldingly resistant contact with the rollers 201 and 165 by means ofthe spring 231. It

will thus be( discerned that the yoke members 228. 229'carried by the shaft 230 are so arranged as to permit the use of but a single spring at each end of the shaft each acting Epon both an upper and a lower yoke memvExperience teaches that where paper is fed in such a manner as to present slack there is a very objectionable tendency of the paper to distort and crumple, to overcome which there is here provided -a guide member 232 to impart some transverse., curvature. y

For severing the required piece of paper from the strip. G there is provided a shearing knife, 233. co-acting with a stationary cutting block 234. The cutte 233 is carried bythe crank 235 on the shaft 236 towhich is .pivoted one end of the'lever237 (see Figure 6) the other end of which ispivoted to the connecting lrod 238 having at the opposite end a woke 239 engaging an eccentricl 240 on the shaft 206 abovereferred to. thus providing the cut-ter 233--with an oscillatory motion. As a result ofthis the cutter 233 is moved bodily towards the block 234 inthe arc of a circle. Further, to enhance the cut- .ting action of the shear 233, its active edge is beveled and the co-acting ledge of 'the block 234 is complementarilyA beveled as is clearly to be seen on inspection of Figure 2.

For feeding the paper strip G substantially vertically downwardlyabetween the cutters 233, 234 the guide\241 is provided which serves to direct the paper in the desiredrelation to the knives,` l Y i The paper is further guided into position to bestruckby the collected bunch I of gum 245 of the slot 244 serves as a lilnit stop for the movement of the wrapper H.

The intermittent movement of the cutterl -233 and of the lower feed rolls 165, 166 are so co-ordinated that the cutters act whilst the rolls are stationary.

Inasmuch as it is necessary to prevent ac.- cumulation of paper between the pairs of rolls 2,00, 201 and 165, 166 theI lower rolls 165, 166 must not only be driven at a much higher average rate of peripheral speed than the upper rolls 200. 201 in order to feed the paper intermittently downwardly but also desirably have an additional slight increment ofaverage speed in order to prevent any possibility of such accumulation of paper.

Again referring to Figures 2 and 3, the chains 162 are driven by the right hand pair of sprockets 164 mounted upon the shaft 246 carrying the gear 247 in mesh with the pinion 248 on the-shaft- 249, (Figure 6), 1n turn carrying the elliptical gear 250 in mesh with I another elliptical gear 251 on the shaft 206 above referred to.

As above suggested, the chains 162 carry a pair of fingers 163 beneat-h the sticks of gum grouped upon the platform or supporting members 154 at a time when a predetermined number have been accumulated upon such platform members, and the continued lmovement of said fingers 163 carries such sticks in a. group along the passage 252 and into contact withV the wrapper H, (Figure 4). cut from the paper strip G and positioned as previously described, it being understood that the location of the fingers 163 on the chains 162 issuch that they move the gum sticks I against the 4wrapper H at a time when the wrapper H is stationary.

As the fingers 163 advance thel grouped gum sticks I 4throughthe passage 252 and strike the wrapperl IH, they carry along througlr'a passage253 the gum sticks with the wrapper which through contact with the edges of the passage'253 is folded against the asseml'iled gum sticks.

l`rlhe relation of the assembled gum sticks to the wrapper H is such that the lowermost port-ion of the wrapper H is shorter than the width of the gum sticks, whereas the outermost, portion is longer, and consequent.- lv the folding of the lowermost portion of the wrapper H is completed, whereas the uppermost portion has an extending flap J (Figure 4). 1

. For receiving the partially wrapped package andy folding the outstanding flap J thereupon thereis providedxa radially slot-fl ted conveyor 254. The several slots 255 y thereof are "so spaced and arranged asl sue-l cessively to form substantial contirmation's'v sticksby means ofthe angularly arranged Kef the passages 252 and 253 and of a depth guides-242, 243. A- guide slot 244 is provided to receive the' loweixedge of the wrap- Ber H cut from'the strip G and the bottom just sufficient to accommodate the partly'` wrapped group wlth the flap-J extending outwardly beyond the conveyer. 13C- As the fingers 163 advance the grouped gum sticks with thewrapper in posltion through the passage 253 towards the barrel 254, the advanced end walls of the projecting portions of the wrapper `are brought into contact withqtuckers- 256v beveled on' their forward redges 257, thus folding only the advanced proJecting walls of the wrapper H, and scoring the adjacent portions of the Wrapper H. At the time the fingers 163 move the group I of gum sticks, theyare moving at a comparatively slow 'rate..

lVhen, therefore,- the" fingers 163 have advanced the'p'artially wrapped group of gum sticks into the slot 255, of -the barrel,2`54, an initial fold has been given to the outer ends of the wrapper H and vit is prepared ,for

' Afurther folding operations.

It will be. speeiauymd that inasmuch as the tuckers 256 are acting upon the advanced wall ofthe projecting portions of the wrapper H simultaneously with folding barrel 254 is divided `as vshown in' Figure 7,

to provide reduced concentric portions ,254* which are rotatably supported `in bearings,

2541?.v The gearing describedstarts the rotation ofthe barrel 254 lat a high initial rate ofl speed at the time theffingers163 'aref moving the articles into 4the slots of the'r barrel slowly, thus avoiding interference between-,the movements'im arted to the gum .sticks I in different directlons by these two instrumentalities. This gearing also brings the barrel 254 to rest slowly so that when it brings the gum sticks to the ,position from which they are removed-by the fingers163,

its movement is slouw, but the rate ofmovement of the fingers at this point is high.-

ment of the fingers 163.v

Inasmuch as the advantages ofla' radial- Y arrangement of the slots 255 and of a movement of the fingers163 diam'etrically of they` barrel 254 are obvious, the shaft -221 has been so positioned as to be out of the path 4of movement of the fingers 163 which has been accomplished by providing the barrel l 254 with the/internal gear 259 meshing with the pinion 258,*above referred-to, as a result of which the shaft- 221 may" be mounted f eccentrically ofthe axis of rotation ofthe barrel 254 and out ofv the Vpath of move- Lavazza? i It will be'further observed that'the posil tion of the wrapper H when struck by the grouped gum'sticks C is spaced from the barrel v254 and that therefore the initial folding of the wrapper H takes place while the group of sticks is beinggfed through the passage 253 and before it reaches the slot 255 of the barrel 254, thus additionally avoiding any abra'sure of the margins of said-slot and any distortion of the wrapper H.

1t 'has been above pointed out in connection with Figure 2 that the chains 162 are driven through the 'medium 'of the elliptical gears 250,- 251.` As aresult of this, the fin-` gers 163 are at times given -a retarded move'- rment and .at other times an accelerated movement. The barrel 254 is driven through the medium ofthe shaft 221 and this shaft has been described as given an intermittent movement with a quick start and a slow stop by virtue -of the employment of the elli-ptical gears 226, 227 and the star-wheel 222.. The movements of the barrel 254 and of the fingers 163 'are so synchronized that the fingers move slowly -while the s lot 255 is opposite to the passage 253 ,long enough to advance the. group of gum sticks fully into the. slot 255, immediately upon which the barrel 254 is given an accelerated rotatory movement quickly withdrawing the group of gum .sticks C from the path bf movement of the fingers 163 and simultaneously the fingers continue their phase ofi retarded .movement thereby permitting the removal of the grouped gum sticks without interference or with the fingers 163.-

ReferringA now toFigure 4, as the barrel i 254 revolves contra-clockwise, eachl succeeding flap J is bent against the-perimeter of thebarrel 254 by means of the folding block 260. As each fla-preaches the position indicated at J', the barrel stops there with the flap J insuch osition, for the ejection of another partial y wrapped group I of gum sticks from the s106255"l into passage 261, which latter Ais now in alignment therewith.

This passage 261 is formed betweenthe I lower surface ofthe block 260 and theguides l 111, and at eachgside of the passage 261 ,is disposed latucker 262 andl the co-acting folders 26a, 264.`

In the position of the barrel 254 shown in Figure 4,'it-willibe appreciated that while one pair of the fingers 163 is moving a group of gum sticks into'the slot 255, another pair of such fingers 163 isfremoving the partially wrapped-group ofrom the .slot 255a into the i i passage' 261 and, due tothe contact .of the fiap J with the block 260, this causes such flap. J to be folded' down .upon the theretofore completely- ,folded short flap of the wrapper H.l This' completes the initial wrapping of the group I of gum sticks save for the folding of the projecting ends of the wrapper J, andthe sealing hereinafter set forth. t

This end folding is accomplished by means of the -tuckers 262 which act on the now forward (formerly rear) wall of the pro- 'ectiner wra )er J and scorinf the ad'acent :I 2D D portions of the wrapper H. vAt this point the wrapper has upper and lower projecting flaps ateach side. As the package is moved still further along the passage 261 these projecting flaps are bent against the end walls l of the package by the co-acting folders, 263,-

264 so arranged that the upper flaps are firstfolded down against the package by the forward edges of the folders 263 aud the lower aps then folded upwardly upon such upper flaps by the forward edges of the folders 264.

The block 260 and the co'acting folders 263, 264 may be heated in order to soften the paratlin with which the wrapper l-l is co-ated. This heating'in'ay be effected by meansof lelectrical resistance coils 265, 266, the structure of which is illustrated in Figures 10 and `11. The purpose of this heating is to fix the fi'ap J against the short flap, and to fix the end flaps down in position uponthepackage, thus effecting the provision of a package which is not only compact and held against accidental opening, but also one which ishermetically sealed against the entrance of air or moisture, both of which tend tothe deterioration of the gum sticks contained within the package.

From the foregoing description it is apparent that the paraiiin heating and paper folding operations are carried on simultaneously, that the passage of the flap J against the block 260 and of the top aps against the folders 263 and ofl the bottom aps against lthe folders 264 not only fold the flaps but also soften the paraffin soI thatsealing is effected immediatel uponl pres` `sure exertedl upon such flaps y said meinbers 260. 263, 264. For 'further assurance of a tightseal, cooler plates 267, 268, 269

4are provided for accelerating the dispersal of heat from the top and ends ofthe package,l and thereby the solidiication 0`f the paraffin. i

The variable rate of movement of athe iin- 'gers 163 is utilized to retard vthe movement ofthe groups ofwrapped gum sticks asthe pass the heat Sealers and the plates 267, 268, 269 or any of them.

As thepackage wrapped and sealed, as just above described, is moved from the position indicated at C3, Figure 5, a label K. is presented across its path of movement through the passage 261?. The stream of labels or ex'teriorbands lK may-be fed into" position by the mechanism -shown which lcomprises the`hop`per 270, se arator 271g,

gearing indicated generally at 2 2 and asso--v4 ciated parts,- all fully'described and claimed inthe copendilng companion application of4 gearing 272 is driven by the shafts 273 and the separator 2714 is driven by the shaft 274. These .two shafts are provided with intermeshing gear 275, 276 and on the shaft 273 is mounted the gear 277 meshing with a gear 278, on a shaft 279, which latter gear in turn meshes ,with the pinion 208l heretofore described. .i

Here too as is the case with the wrapper H, the band or exterior labelK is positioned so that the initial folding thereof is accomplished as the wrapped package I of gum sticks traverses the slot 280. from the passage 261, within whichslot 280 the band K is positioned bymeans of a delector 281 and spring-actuated oscillating presser members 282. to a second rotating conveyer 283. The band K is so positioned in the slot 280 that in this initial folding the lowermost part of the band Kis folded against the wrapped package and the uppermost portion thereof 'L veyer barrel, 254. has a similar series of radial slots 284 jinto which the fully wrapped and partially banded packages are succesy sively-fed by the. lingers"f163-` This barrel 283 is intermittently driven with a step-by-step movement having a quick start and a. slow stop, by' means ofthe internal gear 285 with which meshes the pinion 28,6 onl the shaft 287 which carries a star` y wheel 288 rotated step-bv-stepv bv means of the pin 289 on .the crank 290 carriedbv the shaft 291 having .an elliptical gear 292 in meshv with another elliptical gear 293 on the stub shaft 279 carrying the gear 278 in turn in mesh with the pinion-208 heretofore 'referred to.

The mechanism for rotatingxthe barrel 283 i is injallsubstantial respects similar to that employed for rotating the lbarrel 254, and

.there is a similar coordination of the movementsof the barrel283 and of the fingers 163 for the purpose of removingthe wrapped and partially bandedp-ackage from the path of movement scribed.

pon the shaft 291 b v which motion is im'- parted to the star-wheel immediatelv abovey y ,described there is mounted a crank 294,and

an/ eccentric-295,4 (Figures 1l and ,5). this-crank 294 is pivoted a link y296 in turn pivoted to anarm 297`piv'oted at 298 to a stub shaft 299 (seeFigure 1). The arm 297 .carries at its outer end an 'oscillating flap of s u'ch fingers. as above def reversing rod 300 which xwhen it moves I clockwise passes over the free edge of the extended bandflap and then when it .moves 'contra-clockwise passes undef` the band flap and bends it intothe position indicated at L in Figure 5. l

"On continued movementU of the barrel 283 l y and while' the reversing'rod 300 isholding the flap L in the position indicated,- this flap is directed against a guide block 301 provided vvitha curved, guiding surface 302 along which tiap L lmoves eventually upon release of the tension due to bending. directing itself toward the roller 303 upon the surface of which adhesive is fed by gravity from the reservoir 304 through the 305.

The eccentric 295 carries a: yoke 306 to the a opposite end of which ispivoted at 307 a link 308 carried by the stub -shaft 309 and spring pressediinto driving engagement with the presser bar 310 also carried on said stub shaft 309. I

Again reverting to Figure 1, it will be noticed that the eccentric 295 and associated parts are so proportioned and arranged as to bring the presser bar 310 into contact with the flap L While the barrel 283 is momentarily stationary with the flap L closely adjacent to the adhesive feeding roll 303. i The extent 'ofmovement of the presser bar 310 is such as to cause'said bar 310 tofpress the ap L againstfthe feed roller 303 and there- Vby apply adhesive/ tothe inner margin of the flap L.

As. additional' increments of motion are imparted to thebarrel 2183 and the fiap'L finally-comes into contact with the folder 311 the completed package is removed from the slot 284a by means of theloscillating ej ector fork 312 reciprocated by the shaft 313, (Figures 1 and 6), which is moved bythe crank 314 pivoted to one end of a connecting rod 315, the other end ofwhich isprovided with va yoke mounted upon the eccentric 316 carried by the stub shaft 279 driven by the driven as'. previously set forth.

intermeshing ,gears 278 and 208 heretofore referred t0.

In order to provide an adequate feed of adhesive from the reservoir 304` the roller -303 is driven intermittentlv bv the shaft-317 carrying the gear 318 in mesh with the pinion, 319 upon thej shaft 287 intermittently For controlling the iow of adhesive from 'the reservoir 304, the 4spreader 320 is made upon stoppage ofthe gear 211, the'collar 32.5, which is held in rotatable engagement with the collar 326 onthe 'gear 211, `by the torsion spring 327, continues torotate relatively to the collar 326. Upon such continued movement the pins-328, which'rest in opening gers projecting therefrom, means for drivfingers projecting therefrom, a platform ex- .ing said shaft at an irregular rate, a platan' annular depression 329 in the-collar 326 is forced to the left into engagement with lthe yoke 330 (see Figure 3) on' the shifting bar 331 pivoted at 'its upper end tothe bracket 332 and engaging at its lower end the` collar 333 on the slide rod 334 which actuates the main clutch (not shown) connecting thel line shaft to the source of power.
