APPARATUS ECR PRODUCING SEALED WRAPPED PACKAGES.

Appiitin inea July 2s,

Be it known that VrLLIAM A. liVnrCi-iTMAN and CHARLES H. NrrsoH both citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Apparatus for Producing Sealed Wrapped Packages, of which the following is a specification. y

This invention relates tofthe art of pro-- dncing sealed wrapped packages.l pertainingtype yhaving the advantage of tightly vfitting the packet and remainingl on the packet even after the package has been oijiened to `@rain access to the packet contents.

The wrapper' employed in this type is `generally in the form of a blank having` its body portion made np of connected sections corresponding substantially to the contour and area of the packet walls which each is to cover togetherwith a marginal top lap, the sections having end wings or laps which are applied `at the ends of the packet the wings or laps having' shapes which when applied will produce coverings for the packet ends. One face of the blank is adhesively coated and this face is adherently applied to the walls and ends of the packet, this latter operation being generally provided by covering apparatus formed of a plurality of covering instrumentalities which operate in predetermined cyclesto produce the wrapped` effect.

.As will be uinlc-irstood.v they formation of a commercial package of this type involves an accurate registration of the packet and blank vin order that the covering operations may bring the sections, etc., in proper position on the walls and ends of the packet. To provide this accurate registration is more or less of a problem due to the length of the blank and to the yfact tb at, after receiving its Specification of Letters Patent.

adhesive coating,` the coated blank mustbe properly positioned in order that the packet may be brought into registration contact therewith. This problem is made more diflicult where it is desired to provide a more or less automatic operation, since the conditions are such that the point of adhesive application is generally spaced from the pointwhere the blankmust be positioned at the commencement of the coveringA operations thus complicating the problem by the necessity for transferring the adhesivelycoated blank from the adhesive-applying mechanism to the covering instrunientalities. To transfer the lengthy thin and flexible blank with its adhesive coating and accurately deliver it in position to receive the packet becomes a serious problem since the blank must be drawn in the direction of its length and while coated.y tending to limit the speed of travel of the blank and thus increase the time required to transfer it, this latter in turn tending torincrease the inherent curling effect produced by the setting of the adhesive. Manual transporting and positioning is more or less diiiicult due to the necessity for handlingr a. thin flexible wrapper of considerable length and other dimensions when one face of the blank is entirely covered with the adhesive. i

The methods by which these problems are met aredisclosed generally in our companion application filed June 29, 1917, Ser. No. 177,832, the present invention pertaining more particularly to one embodiment of apparatus for carrying lout the methods disclosed in the said companion application. As pointed out in thesaid application, the

solution of these problems is had primarily by supporting the blank during` the adhesive-applying operation7 and, while so supportefh bringing the packet and blank into registration contact" thus assembling the packet and coated blank by applying a face of the packet to the complemental portion of the adhesive face of the blank, thereby providing an extended connection between the two parts and producing an assembly such as will enable the packet to serve as the means for drawing the coated blank during the transfer of the latter from the point of adhesive application to the covering instruinentalities. As a result.y the movement `of the assembly can be provided by bodily moving` the packet, permitting` the latter to be automatically the general solutions referred to lin 'the companion application, the apparatus embodying various instrumentalities which are co-related in operation in such manner as to produce the automatic action.

Tothese 'and other ends, the nature of which Will be readily understood as the inventionl is hereinafter disclosed, ysaid invention consists in the improved construction and combination of parts, hereinafter fully described, illustrated in the accompanying` drawings, and more particularly pointedv out 1n the` appended claims.

wapparatus, a brief description o Fig. 14C isa detail sectional vieivof parts shown in Fig. 4c with parts changed to accord with Fig. 13.

Before giving a detail descri tion of the e general operation is given.

The Wrapped package which forms the.

product of the apparatusis shown in Fig. l2, this being made up of the packet P and ,ywrapper W,these beingshown in assembled relation in Fig. 6, it being understood. of`

course, ,that this assembly takes place through the operation of the apparatus. The packet P1 `is .representative of a container carrying a commodity or it may be the coin- `inodity itself, itbeing preferably of angular contour. The'wrapper is formed of four connected sections a, b, c, and together with a top lap e, these all being integrally connected together and practically constituting the length of the Wrapper; The several Wrapper sections are provided With end Wings or laps a', b', c and 0l', these Wings being of suitable contour, the form shown in the drawings having `Wings b and d of less projecting length than Wings a and c, the

causing these Wings to be folded at the ends of the packet practically as shown in Fig. 12.

The assemblage and the'successive Wrapping operations are shown generally in Figs. 5 to 12, Fig, 5 indicating the manner in which the packet and Wrap erare brought into registration contact, t e feed yof the voperations of the covering instrumentalities packet and Wrapper being such as to cause fully described, this assembly of packet and Wrapper takes place While the Wrapper is supported'by a platen on which the wrapper is supported While receiving its adhesive coating, the assembly being providedwhile both Wrapper and packet are advancing, the advance movement placing the top lap e, of comparatively narrow Width, in advance of the packet, sections Z1, c and d trailing behind the packet, as shown in F ig. 6. g

This assembly is transferred'bodily by continuing the advance movement, until it reaches a osition .in proper alinement with the initia` folding or covering instrumentality and at the entrance of the latter, Where the downward movement of a plunger carries the packet through the first folding or Wrapping instrumentality into` a rotatable carrier or turret. This movement applies section b and top lap e to the proper Walls of the packet and at the same'M time turns Wings a into contact With the ends of the packet, as shown in Fig. 7. Rdtation of the turret carries the assembly past a wiping brush or roll which applies section c to its proper face of the packet.:l

. tinued travel of the turret then folds in the end flap 7)', (Fig. l0), the turret stopping opposite an additional wrapping instrumentality,wvell-like in character, the assembly being in the form shown in Fig. 10 at this point. The assembly ist-hen moved out ofl the turret into thewell, this movement applying the last sectioned-to.theproper.. faceof the packet and into overlappingw relation to top lap e, as shown in Fig. l1.,

Upon completion of this action, end wings ci are folded in, producing the configura tion of Fig. 12, and the Wrapped package is then moved out ot the apparatus and delivered at the desired point.

A number oi' advantages result from this general sequence of operations.

The assemblage takes place While the wrapper vWith its freshly-applied adhesive is located on its supporting platen and bcore the Wrapper begins any material movementin its own plane tovvard the wrapping instrumentalities. Hence, instead of attempting to advance a thin adhesively-coated and lengthy Wrapper for a considerable distance in its ovvn plane by the use or' grippers, and attempting to properly position the Wrapper with respect to the packet so as to lproduce registration, the registration is provided in advance and the extended connection between the packet and section will insure a proper advance of the assembly by simply advancing the packet. Hence the advance movement may be at greater speed and Without liability of damage to the Wrapper.

Furthermore, the production of the assembly provides an additional advantage in that covering of one Wall or tace ot the packet is completed before the advance travel has .carried the assembly into the main covering instrumentalities.

Another feature is the tact that the ivrappingoperation practically extends successively and progressively throughout the length of the section portion of the Wrapper, one section .after another being applied until the Wrapper is completely applied, the result being that there is tendency to dran7 or Wipe the last applied section into close contact with the Wall so as to reduce the liability of forming blisters, this drawing or wiping action being made possible Without liability of destroying registration by reason of the fact that the adhesive connection of section a, and the packet has taken place suiiiciently in advance of the initial wiping action as to permit the adhesive to set to a more or less extent.

lVhile the sections are applied. in regular progression in the direction ot length oi the Wrapper, the end Wings are applied in an irregular progression, as indicated in the above description, the result being that the outer applied Wings are thus connected to spaced apart sections, these latter Wings being adhesively-connected to the previously folded Wings and to the ends ot the packet.

In the present apparatus the Wrappers and packets are brought to assembling position from magazines which are adapted to carry a plurality of each, suitable delivery mechanisms being employed to bring the individual elements to the point ot assembly. Obviously, various types ot delivery mechanisms may be employed, the drawings indicating one embodiment ot each -ivhich is operative to produce the desired result, it being understood, ot course, that other mechanisms may be employed as equivaient structures.

Referring first to the wrapper delivery or teed mechanism7 indicates the general 'trame of the apparatus Which is ot suitable design.

Mounted on suitable slides 2() carried by the iframe is a carrier frame 2l adapted to be reciprocated by the action of .suitably-l driven cam 22 (Fig. 2) operatively connected to the carrier frame through bell crank lever structure andy link connections 24, cam 22 being carried Yby a drive shaft 25. Frame 2l. forms a support for a table 26, the latter being supported yieldably by springs 27. Table 26 is adapted to support the blanks, guides 2S,.having inturned yfianges or stops .2811, serving to re tain thc blanks in position. Guides 2S are carried by the frame, and stops 282l serve 'to limit the upward movement of the table through contact ot the top-most blank with these stops 28, springs 27 tending to hold the topmost blank in contact with the stops. Depending from table 26 is an arm 29 having teeth 29:l which are adapted to co-operate with a paivl 3() carried by a bell crank .'1 ncture 3l, this structure including .a roller S2 adapted to `co-operate with a member 3S having a cam face 33,

ris will be understood, reciprocating movementof iframe 2l will canse roller 32 to travel over face 33, thus causing ybell crank structure 3l. Ato be oscillated as the iframe travels backward and forward. This oscillation of bell crank structure 3]. in one direction causes pan/l 30 to engage a tooth 2.9a of arm 29 and move said arm and table downwardly against the tension ot springs 27, thereby carrying the top blank of the pile out ot' contact with stops 28a. 0scillation of structure 3l in the opposite direction-permits springs 27 to move the table upward until the top blank contacts with stops 28u.

Se indicates the suction member ol' a suitable suction-creating and controlling mechanism (not shown), this member being mounted above the blanks, as shown in Fig. l. and having a perforation or perforations which are adapted to be brought into operative relation to theV upper blank-on the table. Member 34 is rotatable, the rotation being had by a rack and gear connection Witlr frame 2l, the reciprocating movements ot the latter causing member Sil to be oscillated.

As will be readily understood, the suction action of'member 34 will cause the top blankto adhere. to this member, yand when frame 2l moves forward, carrying the pile of blanks in this direction, member B4 will be moved to raise the front end of the topmost blank into the' Zone of operation of a pair of feed rolls 3G which operate to feed `the blank. During this advance movement of' the frame and While the topmostv blank is 4 thus engaged, roller 32 will become active to lower table 26, thus leaving the top `blank free to be Withdrawnv from the pile of blanks by the action of the :feed rolls 36.

37 indicatesa rotatable blank-supporting platen having suitable grip mechanism '37 f by means of which thefadvance end of a blank fed by rolls 3G will be gripped and drawn onto the surface of the platen. This platen structure is of any desired type, various forms being well-known in the art.

The particular delivery mechanism above briefly described is, as explained, simply representative of mechanism for this purpose,it being understood that other indi-i.

vidual delivery `mechanisms may be employed', Where. such mechanisms are of a 'type which will deliver a blank to feed rolls which will in turn deliverthe blank being fed to the blankadvancing support, the lat-' ter, in the present instancabeing indicated by platen 37, i

After the advancing blank "has been gripped by the gripping*mechanisms 3W, advance of the blank brings the outer face v.of the blank into the zone yof operation of adhesive-applying mechanism `shown as in the form of a pair of' adhesive-applying rolls 38 carried by a frame 39 rolls 38 being adapted to receive the adhesive from a suitable tank 40 by means of` take-upy roll v41` and distributor roll 42 This general arrangement of adhesive-applying mechanism is Well-known and is not described in de-` tail, it being understood that any one of a number of different types of mechanisms for this `purpose may be employed, a pre-il ferred form of mechanism being adapted to apply a coating of adhesive throughout the exposed `face of the Wrapper blank.

While not absolutely essential, `it is preferred to provide an additional travelling support or conveyor for the blank and the assembly, `this being shown as in the forni `of a plurality of endless bands 43 which eX- tend partially around platen. 37, (Figs. l

` and `5) and over which the gripped-blank y asf extends While on the platen, bands 4B leading over a table top in the direction of advance ofthe assembly, the return flight being located beneath table top a suitable belt tightening mechanism, indicated at 44,

being employed to maintain the conveyor taut.

It will therefore be understood, that the several mechanisms described Will automatically pick the top' blank from the pileof blanks, deliver the blank to platen 37 over conveyor 43, and, While4 the blankis` located on theplaten, it Will have, its exposed face coated with` an adhesiveflm.

As the platen andy conveyor 43"continuef their movements, the coated blank Will be led off of theplaten by the `upper run or flight of the conveyor, gripping mechanism 37 being operated `at the proper time t0 permit this action to take place. y

l'effore the blank is actually led fromthe platen.y the packet is broughtvinto position there its lower face will contact with .the

y `ed outer face of the blank, this being pi ,vided by the :following mechanism:

45 indicates a magazine for the packets,

this being of suitable type, preferablyv ad- 'son linstable to accommodate fordifferent t pes of packets,this magazine being located a ove the plane of' the top of table m andiin rear of the point Where the blank is kbrou'ghtto theA plane of such table top. The magazine is'arranged in such manner that the lowermost packet therein is free to advance over the table top bythe action of suitable advancing v mechanism, a preferred arrangement of which is shown as in the form of a pair of endless chains 46 located on opposite sides ofthe'path of travel of the packet, which chains at opposite ends of the packet. i

lib-ich chain 4G carries a plurality of elements 49 which contact with the rear face of' the packet and push the packet along the table top as the l'chains advance.` `Elements 49 may be of variousytypes, a simple and preferred arrangement being to employ a rigid portion 49TL and a, yielding finger 49b carried by portion 49'. Portions 49El project from the chain a distance sufficient to contact with the rear face `of the packet While in the straight flight of the chain. However, when the advance of the element carries it to a point rWhere the chain flight passes out of the straight path in roundingA sy'nocket wheel 4S, the movement of the chain causes portion 49A to be Withdrawn from contact with the packetfrear face, leaving finger 49b in contact. The supporting spring1 for finger 491?` is of sufficient power to continue the advance of the packet as long as the. latter is not restrained from ad- Yvancing. When, however, the advance `face of the packet passes into contact with adjustf able stop members 50, thus preventing further advance movement of the packet, fingers p49 will yield and permit theelements to pass by the packet, thus` leaving the latter` positioned as to locate the packet at the proper point for `further operation by the covering instrumentalities.

Chains i6 are operatively connected to tra vel in unison and elements 49 are positioned so that one element from each chain becomes active simultaneouslyon a packet,

the result being that the packet will be ad-..

vanced in a predetermined path and at a uniform speed.

During kthe advance of the packet it is brought directly over and in contact with the exposed tace of the blank which is carried by platen 37, the several blank advancing instrumentalities having their operations timed in such manner, relative to the movements of the packet, that the advancing packet will be presented in proper registration with the complemental section oit the blank. As will be seen fromFig. 5,

the advancing blank has its direction of length extending on the arc of a circle formedby the platen while the advancing packet is travelling in a horizontal plane which corresponds to a tangent of' this are..

i plied to produce the adhesive connection between the packet and blank, the packet is caused to pass beneath a pair of' yielding platesl, these plates providing downward pressure on the packet at the time the lower y face ot the latter is being applied to the wrapper section. As a result, a proper adherentl connectionjis provided vbetween the packet and blank while the blank; is supported by the platen, the completion of this connection by the advance of both packet and blank completing the covering of this -face of the packet.

As will be readily understood, the come pletiony of this assembly betere the blank has made any material movement toward the covering instrumentalities a't'ter leaving the platen, eliminates any necessity, tor the use oit' gripping or other mechanisms for advancing the adhesively-coated blank, since the packet itself serves as an advancing means for the blank, the extended adhesive connection between the'blank andl packet providing a ifar more efficient means for advancing the blank than could be, providedv by gripping mechanism which would be required to grip a comparatively thin blank wetted by the adhesive. Hence the blank is not only properly and accurately advanced without the use oi' grips or other means for grasping the blank, but the contact between the packet and blank is at such point-advance section qfthat the major portion of the blank, in trailing the packet, is practically unaffected bythe advancing movement of the assembly. Bands 43 not only aidin providing this result, but also `tend to prevent smearing' or otherwise disiiguring any printing matter which may be contained on the lower face of-theblank during this travel. As a result, the blankymay be of comparativelythin stock without liability of being damaged during ,the assembly advance even though the latter be at considerable speed.

Suitable provision is made tor preventing contact of rollers 3S and the face of platen n 37 uponftailure of proper feeding of a blank to the platen, the particular mechanism for n'oviding this result not being specifically described, various devices of the art being available for the purpose.

Stops 50 are so positioned in the path of advancingmovement of the packet as to locate the latterin proper alinement with. a vertically reciprocating plunger 52-which is operative to carry the assembly intol the wrapping instrumentalities. Thisl position ot' the assembly places section a of the wrapper directly over a pair of hinged yieldable supports 53, the latter being adapted `to normally support the weight of the assembly and being yieldable downwardly when plunger 52 becomes active to shift the assemblage downward. Supports 53, during this downward movement of the -assembly serve to told wings a into contact with the ends ol.E the packet (F ig. 4t), thus positively afli'ic ing section a to the packet and preventing liability ot relative shifting of blank and packet at the start ot the wrapping operation. During the earlier portion of the downward movement of the assembly, the`r wrapper is brought into Contact with a pair ot' wiping elements in the form of brushes 34-, these brushes serving to wipe lap e into contact with one tace of the packet and section 7) et the blank into contact with the opposite Alace o'f the packet. As the assembly continues its movement, it successivelypasses into contact with brushes 55 (which act to provide awiping action on the folded wings a) and into Vcontact with rollers 56 (which act to smooth section 7) and lap c of the blank in their applied positions).

This provides the result indicated in Fig. 7, in which form the assembly` is positioned in a rotatable carriershown as in the form' 1120 of a `turret-movable on a horizontal axis.

The turret is shown asprovided witha plurality oi'l assembly-receiving structures,

f these structures being arranged in pairs ,with

each pair alined on a diameter of the turret,"

sembly is positioned and held. during move-a mentsI of the turret. Eafchpair of'structures is `provided with a reciprocatingmember 58 Y having its opposite ends formed with'heads o r platens 58, each platenl operating in one .ofA the structures, the length of each member 'y58-beingsuch that when the face of one `platen '58EL is incontact'with a positioned vasi sembly,the face of the opposite platen will be` approximately at lthe entrance of the structure within which it operates.

f turret larrangement is such that the platen tering assembly -is normally positioned at 58a which is in the path of travel of the enthe outer end of the structure which is to receive the assembly. Consequently, when the assemblyl advances under the continued' movement of plunger 52, it contacts with the4 advanced platen 58 and moves member 58 toward its opposite extreme of movement,`

this platen thus forming an element on which the assemblyy rests while positioned in the turret, the'opposite platen serving to deliver ya previously positioned `assembly as presently described.'

As shown in Figs. 3 and 4, members 58 preferably extend in parallel planes, and

.each member is mounted in a rotatable sup-` port 59, extendingtlirough the latter. The

support 59 is provided with cavities 59", closed by members 60, these members being Y {yieldably supported by springs 60 and forniing elements normally projecting beyond the end of vthe support and therefore `in the path of movement of theplaten 58a which is being moved by the entering assembly1 the movementsof `plunger being suoli ythatthe assembly will bemoved into its `receiving structure a distance sufficient to move element 60 inwardly and provide com'` pression of itssupporting spring 60a. However, `as soon as plunger 52begins its return imovement, the pressure on platen 58' will be released, and the compressed spring 60 :will return element 60 to its outer position,

ythus shifting the entering assembly out'- -wardly a :small distance and positioning it for further operation.

an appreciable distance beyond lthe path of "travel of the turret (Fig. l) thus enabling al charged fromthe turret. The turret is op` eratively connected upto the drive shaft 1t may be noted at this point that this temporary excess movement of member 58 fis jdesigned mainly for the purpose of moving the opposite platen a distance sufficient to carry the previously-positioned assembly proper moyement of the turret to be had without being affected'by an assembly disy"to provide for intermittent step by steprovtating movement, the movements being of l-aialength to position the assembly-receiviimr `4structures successively in position toreceive .an advancing assembly, dwell'in the move- *ment ofthe turret being provided while an assembly is being introduced and pOSQIlFd.

The

'sult shown in Fig. 11.

` After an assembly hafslbeen introduced into itsstructure, rotation of the turret carries'it through an angular distance of` 90 which then places the assembly in the p0- sition shown at the left "in Fig.' 1, the suc-A- ceeding receiving structure passing into position to receive the succeeding assembly. During travel of the assembly to this position, it passes a revolving brush 61 which serves to apply section o of the trailing* poition of the carrier in Figi 7 on to its complemental face of the packet,` placing the assembly inthe condition shown in Fig. 8. After the assembl reaches the position shown at `the left in P ig. l and during the period of Vdwell in such position, wiping instrumentalities, `preferably in the form of y rollers 62, are actuated to turn in wings c and apply these wings to theends of the packet and in overlapping relation to wings e', producing the result shown in Fig. 9.

The succeeding movement of the Aturret places the assembly in the position shown at thebottom `of the turret in Fig. l, and dur? being approximately in the form shown in Fim 10. y

iongitudinal movement of member 58y then takes place by the lintroductionr of an assembly into theopposite`receiving structure, this movement of'member 58 forcing the lower assembly out of its carrying structure and into a wrapping instrumentality located below the turret, this wrapping instrumentality being in the form of wiping rbrushes 64 between which the assembly is vpassed vwhen discharged from the turret, these brushes forming a well-like structure,

one of said brush structures acting to apply the remaining section (l to'the complemental wall of the packet and in overlapping relation to thetop lap e, this action being provided by the downward movement of the assembly, which, as heretofore `ointed out, carries the discharged vassemblage out of the path of travel of the turret and the succeedingassembly, This produces the re- After the assembly is positioned in the well-like structure, the remaining wings d are applied to` the ends of the packet by wiping instriinientalities preferably 'in the form of rolls 65, this operation taking place after the "assembly has come to rest and prior to its succeeding movement which is provided bythe discharge of the succeeding iassembly which acts to push the positioned assembly; 'downward in the Well. During Vizo` this' lattermovement` the ends of the packet are brought into contact with wiping instrumentalities in the lorio. of brushes 66 which smooth out any inaccuracies ot folding of thescends. This completes the wrapping operation, and the completely Wrapped packagcmshoii'n in Fig. 19T-is discliarged troni the iijell when the nextsucceeding` assembly is introduced.
