12 Claims.,

vThis invention relates to a method and apparatus for packaging, and more particularly to a method and apparatus suitable for packaging articles oi confection, such as candy and the like. The invention further relates to a new type of package.

One of the objects of the invention is to provide a new and improved method and a new and improved apparatus for packaging articles and especially for packaging articles of food, such as candy.

Another object of the invention is to provide a method and apparatus for packaging articles of the type described automatically with a minimum amount of handling.

A further object of the invention is to provide a new and improved method and apparatus for packaging articles of the type described in such a way that the articles are individually separated from each other within the package.

Another object oi the invention is to provide a new and improved method andapparatus for packaging articles of the type described in a noninterrupted or continuous manner using a continuous strip of packaging material fed from a roll.

An additional object of the invention is to provide a new and improved type of package or packaged article.

A more specific object of the invention is t0 provide a method and apparatus for packaging articles by plaiting or crimping the end of a continuous strip of flexible sheet material, such as paper, to form longitudinal grooves or channels therein, then feeding or inserting continuous strips of the article into the grooves or channels,

completing formation of the package in continuous strip form, and severing the packaged article of predetermined size from the end of the strip.'

Fig. 17 is a side view of the severing mechanism shown in Fig. 16.

As will be observed, Figs. 9 to 15 are for the purpose of illustrating the method of forming the package and apparatus details which are unnecessary vfor this purpose are omitted. It will be noted further that Figs. 4 and 5 are substantially continuations of Figs. 2 and 3, respectively. As will be further understood the apparatus shown represents only one form of apparatus which can be used for practicing the invention,r

and the structural details thereof may be varied without departing from the invention.

Referring to Figs. l to 5 inclusive, the appa'- ratus shown comprises a pair of horizontal frame members 2 and 4 held together at th'e, ends by transverse frame members 6 (Fig. 2) and B (Fig. 4) and supported from beneath by spaced pairs of frame supporting members Iii-I0, l2l2 and |4-I4. A motor i6, or other suitable power means, is supported by auxiliary frame members generally shown at i8 and 20- in Fig. l.

A roll 22 of paper or other suitable packaging material is rotatably supported on o, shaft 24 freely engaged at either end by supporting members 26 attached to frame members Ill, I0 as generally illustrated in Fig. 1. From the roll 22 a strip A of the paper, or other packaging mateat 3l, 40,

rial, is fed upwardly over a roller 28, as can best be seen by reference to Fig. 3, and then passes into the plaiting or crimping mechanism generally shown at B. 'I'his mechanism constitutes an important part of the invention and comprises a pair of folding or plaiting elements 80 and 82 having complementary grooves, or corrugations therein, which are preferably contoured in a particular way, as will be more fully described hereinafter. The elements 80 and 82 are resiliently held in contact with the strip A on either side thereof by bolts 84 and 88, which pass through brackets or projections generally shown 42 and 44 in Figs. 2 and -3. As will be observed, the brackets 40 and 42 are fastened to the lower member 80 and the

brackets

88 and 44 are fastened to the upper member 82 and are slotted so that the members 80 and 82 may be readily disengaged from each other merely by moving the bolts 84 and 88 outwardly. While the members 80 and 82 are engaged inthe manner shown in Fig. 3,

springs

48, 48, held under compression by

nuts

48, 48 causes the paper strip A to be held resiliently between said members. When the members 88 and 82 are disengaged in the manner previously described, the member 82 may be raised, e. g. as shown in dotted lines in Fig. 1, about the hinge 48 to which it is fastened, by means of hinge members 80 and 82. The lower plaiting member 80 is iixedly attached to the frame members 2 and 4 by means of the =

sup porting members

84, 88, 88 and 80.

The paper strip A is fed or pulled from the continuous roll 22 by two pairs of feed rollers 82, 84, trated in more detail by Fig. '1. Theupper feed rolls 82 and 88 are provided with projections. and recesses adapted to fit into the channels and over the plaits previously formed by the plaiting mechanism B. Thus the plaits and grooves of strip A are preserved by the feed rollers and set 1 in their predetermined shape. The lower feed rollers 84 and 88 preferably have a resilient surface (as for example, rubber or fabric) in order to prevent slippage of the paper.

The feeding mechanism, as generally shown at C in Figs. 2 and 3, comprises a series of supporting members, arms or brackets mounted on the frame members 2 and 4 and generally indicated by the

numerals

18, 12, 14, 18, 18, 80, 82, and 84 in Fig. 3. It |will be understood that a corresponding set of members is provided on the opposite side of the machine. The feed roll 82 is keyed to shaft 84, the feed roll 84 is keyed to shaft 88, the feed roll 88 is keyed to shaft 88 and the feed roll 88 is keyed to shaft 80. The feed rolls 82 and 84 are drivingly connected to each other by means of a pair of gears 82 and 84 mounted on the shafts 84 and 88, respectively, and the

feed rolls

88 and 88 are drivingly connected to each other by means of a pair of

gears

88 and 88 mounted on the

shafts

88 and 80, respectively. The two pairs of feed rolls are further synchronized with each other by a driving connection comprising a chain mounted on a pair of sprockets |02 and |04, which in .turn are keyed to the

shafts

88 and 80, respectively.

Power is supplied to the feeding mechanismC from the motor I8, es shown in Fig. 1, through a chain drive |08 which in turn is drivingly connected to another chain drive |08. Chain drive |08 is drivingly connected to the shaft 88 through a sprocket |0, as shown in Figs. 2 and 7.

From Ithe feeding mechanism C the plaited paper strip is fed forwardly to the

article deand

88, 88, as shown in Fig. 2 and as iilusmessage livery mechanism, generally shown at D and which can best be seen by reference to Figs. 1 and 6. As illustrated, the article delivery mechanism has an elevated frame comprising a pair of oppositely disposed members each including an oblique member II2, a substantially horizontal member ||4 and another oblique member H8. These members are preferably welded together and form an integral unit. Two pairs of upright supporting members ||8, ||8 and |20, |20 are mounted on transverse frame members |22 and |24, which in turn are supported by the longitudinal frame members 2 and 4. A shaft |28 extends through suitable bearings in one end of frame members ||8, ||8 and another shaft |28 extends through suitable bearings in one end of frame members |20, |20. 'I'he arms ||2, ||2 and H8, ||8 are provided at their ends with bearing surfaces and are mounted respectively on the shafts |28 and |28 or, if desired, may be affixed directly to the upright supporting members ||8, ||8 and |20, |20. Abelt conveyor |80 is mounted on the article feeding mechanism D and passes over and between a series of rollers generally indicated at |32, |84, |88, |38, |40 and |42 in Fig.

l. The roller |32 is keyed to shaft |28, which in turn is keyed to sprockets |44 and |48, as shown in Fig. 2. Sprocket |48 is drivingly connected by a, chain |48 to another sprocket |80, which in turn is keyed to shaft 88. Shaft 88 is driven by the feed mechanism drive in the manner previously described. Thus the movement of the belt conveyor |30 is synchronized with the movement of the feeding mechanism A.

'I'he sprocket |44 is drivingly connected through a chain |82 to a sprocket |84, which is keyed to shaft |88, which in turn drives roller 28 and assists in feeding the paper strip A. The

roller 28 can also be an idler roller.

The endless belt is also driven from roller |42 mounted on shaft |28, which is driven by a chain drive |88 from suitable sprocket drive means 80 keyed to shaft |28 and |82 keyed to shaft |84 (see Fig. 4). Shaft |84 is drivingly connected by means of sprocket |88 and chain |88 to a sprocket |10 aillxed to shaft 80 (see Fig. 2). The shaft 80 is driven as a. part of the feed drive mechanism C in the manner previously described and hence the rotation of roller |42 is also synchronized with the rotation of the feed drive.

Since shaft |28 is driven from the feed roll drive mechanism C, the forward movements of paper strips A and E are synchronized.

Mounted on shaft |28 is a sprocket |88, which is drivingly connected by means of a chain 200, or other suitable means, to a sprocket 202 keyed 4to shaft 204 (see Figs. 1 and 4). Roller 208 is fixed to shaft 204 and drives endless belt 208. Referring to Fig. 5, it will be observed that after the candy strips F, or other articles in strip form, are fed downwardly by endless belt |80, they pass into grooves or channels in Ithe paper strip A formed by the plaiting mechanism B, previously described, and the paper strip E is-fed on top of the articles F with the assistance of the endless belt 208. The endless belt 208 is also supported by anidier roller 2l0 mounted on a shaft 2| 2. The shaft 2l2 is supported at either end by a Y-shaped frame member or yoke 2H freely mounted on shaft 204. Shaft 204 is freely supported by arms 2l8 andA 2I8 (see Fig. 4), which are freely mounted at the other end on shaft I2* As will be apparent, the entire endless belt 208 and its driving mechanism may be moved upwardly around shaft t28 or shaft 204, or both. The height of the endless belt 208, with respect to the article F and paper strip A, can be adjusted by

set screws

228, 228 carried by transverse mem- Y ber 222 and provided with

locknuts

224, 224.

The paper strip A is partially assisted in its forward movement by a roll 226 mounted o n shaft ld and preferably having a relatively rough surface for frictional engagement. During its forward movement paper strip A is supported by cross bars 228 and 288 (see Fig. 8) which are adjustably fastened tothe frame members 2 and 4 by

bolts

232, 232 and 284, 234 in

brackets

236, 236 and 288, 288..

Referring to Fig. 5, after the paper strip A passes beyond the roller 222, it is supported by a plate 248, which is likewise affixed to the frame members 2 and 4 in any suitable manner; for example, by means of a transverse supporting member 242 attached to upright frame members 820. The other end of the plate 240 is supported by transverse member 244 and

upright members

246, 246 from the longitudinal frame members 2 and 4.

The longitudinally disposed spacer members 248 are continuations of the sides of the grooves -of the plaiting mechanism A and are provided to assist in maintaining the grooved or corrugated cross-sectional shape of the paper strip A,

The ribs or spacer members 248 are imbedded in cross bars 228 and 280 andare cut away over

rollers

64, 68 and 226. They taper downwardly and terminate beneath roller 208 at point 268.

After the strips of candy. or other article F, have been fed into the grooves or channels in the paper A. as shown in Fig. 5, and the top strip of paper E has been applied and pressed into place by means of the endless belt 208, the continuous package thus formed passes beyond the upright spacing members 248 at point 260, as described. Just beyond the end of the endless belt 208 the marginal edges G and H oi' the paper sheet are folded over the top o f the package by any suitable means, as for example by means of

folders

262 and 264.

The sides of the package are pressed together by the

strips

268 and 258, as shown in Fig. 4. The

strips

268 and 268 are spring pressed toward each other by means of

springs

260 and 262, respectively, and overlap at one end the outer spacer ribs 248, as shown in Fig. 4. The

spring

28,0 is mounted around a bolt 288 which passes through s pair of supporting

members

264 and 288. The supporting

members

264 and 266 in turn are fixed to a transverse supporting member 288, which is fastened by means of bolts or other suitable means to frame members 2 and 4. The bolt 262 is fastened at one end to the side bar 266 and is the opposite side of the machine and causes .the

side member 268 to exert pressure against the` opposite side of the package, thereby decreasingV the width of the package. In a like manner pressure is also applied against the

side members

268 and 268 by

springs

214 and 218 which are mounted on

bolts

218 and 280, respectively.

The

bolts

218 and 280 are supported by vertically Y, disposed

members

282, 284 and 286, 288, respec iron or heat-seal the turned over edges G and Hy of the paper strip A to the top strip E. Heat can also be supplied in any suitable manner tolseal the tips of the corrugations within the package to the inside of the top strip E. One or both surfaces of the materials to be joined may be waxed in order to eiect heat sealing by melting the wax coating, or the packaging materials may be made of cellulose acetate or other thermoplastic material of a type 'suitable for heat sealing.

The continuous package is then severed. into a plurality of packages of predetermined size. This can be accomplished in any suitable manner,

but is preferably done in su'ch a way that the con-` tinuous movement of the packaged material is not substantially interrupted. One method for accomplishing the severing operation is illustrated in the drawings and comprises a vertically reciprocatable knife 284 mounted on a slide block 296 guided by two guide blocks 298 and 800 which are fixed to the inside or upright frame members 802 and 804. A suitable cooperating knife surface 806 is provided beneath the package to cooperate with the knife blade 284. The knife blade 284 is set at an angle, as shown in Fig. 16, and is actuated in a practically instantaneous manner by any suitable mechanism.

Referring to Figs. 16 and 17, one type of mecha-v nism which can be used to actuate the knife blade 294 comprises a double acting piston unit 801'of a conventional type (e. g. Hopkins style 2, vnonrotating double acting air cylinder cushioned,v

made by Tompkins-Johnson Co., J ackson. Michigan, U. S. A.) having means comprising conduits.

388 and 8|8 atv the opposite ends thereof to introduce fluid pressure, such as compressed air. The introduction of the fluid pressure is controlled by a conventional type of valve 3I2 (e. g.'Ross four y Way cam operated' valve made by Ross Operating Valve Company, Detroit, Michigan) which is p ro'- vided with four ports capable of being openedland closed by valve stems generally shown at'3 I4 and 3l6. Fluid pressure is supplied to the valve 812y through conduit 3|6 from a compression chamber 3 I8.

trolled by a valve 322. The arrangement of ports within the valve 812 is conventional and includes an intake port opening to line 8|8, a port to linev 308, a port to line 3l0 and an exhaust port.

thus keep the knife 286 in its up-position.

Upon the actuation of a suitable. actuating n 5 means hereinafter described, iiuid pressure is" caused'to flow through the conduits 308 and 810 provided at the other end with a nut 210 to adjust the tension or pressure of spring 260, which is to be exerted against the sides `of the package.

alternately; that is to say, for example, whenA the valve stem at 3l4v is moved outwardly, com-1 munication .is established by means of suitable 1 The spring 262 is similarly mounted on bolt 22 on The fluid under pressure is introduced into# the pressurechamber 3l8 from a conduit`320 vconi ports i-n the valve 3I2 between the pressure line 3I8 and conduit 308 and at the same time air in the opposite cylinder is exhausted as the piston in cylinder 308 makes one stroke. This causes the knife 294 to move downwardly very rapidly and in fact instantaneously, thereby successively severing packages J, as illustrated in Figs. 4 and 5. A spring 3|8 is provided as a shook absorber for the knife elements.

The means for actuating the valve stem 314 comprise a cam 820 provided with a cam element 322. The cam is fixed to a shaft 324 to which is keyed a sprocket 328 driven by a chain 828` Chain A 328 is driven directly from a suitable sprocket drivingly connected to the motor I8, as shown in Fig. l. The cutting mechanism operates in timed relationship and in synchronism with the movement of the continuous packaged article. A spring 330 is provided to assist the return of the valve to its normal position after movement of the actuating element 332 by the camelement 322. As will be observed, the rocker arm 332 is pivoted at point 334. When the cam element 322 strikes the rocker arm 332, the latter rocks, pulling the valve stem at 3|4 out and pushing the valve stem 3 I 5 inwardly. As soon as the cam element 322 rotates beyond the rocker arm 332, the latter is restored to its normal position by the springs associated with valve unit 3I2 with the assistance of spring 330. 'Ihis opens the valve port to conduit 3I0 and restores the knife 288 to its up-position.

Referring to Figs. 4 and 5 it will be observed that an endless belt 338 is provided to remove the severed packages J from the cutting knife 294. The endless belt 336 is carried 'at one end over a suitable transverse blade member 338 and at the other end by a roller 340 fixed to a shaft 342 driven from a sprocket 344 bya chain 348, which in turn is drivingly connected to a sprocket 348 keyed to shaft |84. The shaft |64 is driven in the manner previously described. Thus, the endless belt 336 is in synchronism with the various other moving parts of the apparatus.

The method of operation may best be understood by reference to Figs. 9 to 15 inclusive. As shown in Fig. 9, the strip of paper A, or other suitable packaging material, is fed continuously from a roll 22 (see Fig. 1) and passes through the plaiting mechanism B, previously described. In the plaiting mechanism the continuous strip of paper A is passed between a pair of

members

30 and 32 having alternatecomplemental laterally disposed grooves and projections running longitudinally and generally converging toward each other. As illustrated in Fig. 10, the lower member 30 is provided with a recess a and the upper member 32 with a complemental projection b. These recesses and projections a and b are separated from each other by complemental projec` tions and recesses c and d in the

members

30 and 32 respectively.

As the paper strip A advances the projections and recesses c and d become deeper and narrower in cross-section, as illustrated in Fig. ll, and

finally assume the contours shown in Fig. l2, at

which point the paper strip A is ready to leave the crimping mechanism. At this point the paper strip A has a plurality of grooved or recessed portions e separated by plaits or folds as shown in Fig. 9. The paper strip A also has marginal areas G and H, previously referred to. It is then drawn through the feed roller mechanism C, previously described, the projecting portions of the

upper feed rollers

32 and 66 traveling in the grooves e of the paper strip A and feeding the paper forwardly to the article delivery mechanism D, previously described, where the article is inserted. In this instance the article shown consists of continuous strips F of taffy-like candy. As the strips of candy F are inserted into the grooves e of the paper strip A from the previously described article delivery mechanism D, a top layer E of waxed paper or other suitable covering material is placed above the candy strips F, in the manner previously described and as generally illustrated in Fig. 9.

As shown in Figs. i3 and i4, the paper strip A, during the delivery of the candy strips F and the application of the top layer E, is traveling on bed plate 240 and the partitions 248 of the bed plate 240 separate the partitions f of the paper, thereby maintaining the predetermined shape of the paper previously fixed by the plaiting mechanism A. As shown in Fig. 14,v the belt 208 presses down nrmly against the top layer e. The marginal edges G and H of the paper strip A extend outwardly, or outwardly and upwardly. Where the continuous length of material passes beneath the belt 208, or at point 250 (see Figs. 4 and 5) the partition strips 248 terminate and at this point the side strips 258 and 253, which tend to converge toward each other, press against the sides of the package and compress it. due to the action of

springs

280, 282, 214 and 218 (see Figs. 4 and 14). At the same time, the folding elements 252 and 254 cause the marginal edges G and H to be folded over the top layer E, as illustrated in F18. 9. The marginal edges G and H are then preferably sealed to the top layer E by

heater elements

230 and 292 disposed directly above the folding elements 252 and 254, as shown in Figs. 4, 5, and 15. A continuous package is thereby formed containing individual strips of candy separated from each other by a partition of the packaging material. The continuous package thus formed is then severed by any suitable type of severing mechanism, as for example that previously described, and the candy packages produced by the severing operation are preferably further wrapped with a suitable wrapper in any suitable manner.

It will be understood that the invention is susceptible of considerable variation Aand modification in the manner of its practical application. For example, the apparatus described is not limited to the use of any particular type of knife or other severing means for severing the articles J.

A continuously rotating knife may be used instead of the vertical reciprocatable knife previously described. It is important from the standpoint of the invention that the knife operate in such a way as not to interfere with the substantially continuous forward movement of the continuous strip A, the article F and any auxiliary packaging materials, such as the top layer E; otherwise, a take-up mechanism would have to be provided to take up the length of material which would accumulate behind the severing means, or it would be necessary to feed the ,various portions of the package, including the article itself, intermittently. and while the apparatus does not preclude the possibility of intermittent feeding, it will be apparent that a continuous operation is much more desirable.

As previously indicated, while the invention is especially suited for packaging candy and the like with a paper packaging material, preferably one which is waxed, it will be understood that other types of packaging material may be used, as for example regenerated cellulose-cellulose acetate, and rubber hydrohalides (Pliofilm). It is preferable to use a material which is suiciently thermoplastic to permit heat sealing in the manner previously described, although it will be under- .stood that in some instances the heat-sealing operation may be omitted. f

Other types of mechanisms may be employed for folding over the marginal edges G and H. For example, instead of a pair of plates 252 and 25d, rollers or endless belts may be used to direct the edges of the paper inwardly toward each other.

Likewise, as will be apparent to those skilled in the art, other types of driving mechanisms and other types of feed mechanisms may be employed without departing from the invention.

The invention provides a new and improved type of compartmented package, and a new and improved method and apparatus for forming such a package.
