MACHINE FOR 'WR-APPING AND GROUPING ARTICLES.

Application filed September 19, 1911.

T 0 aZZ LC/ 20m it may concern Be it known that I, HARRY Y. ARMSTRONG, a citizen of the United States, and a resident of lilgin, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Machines for Wrapping and Grouping Articles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the characters of reference vmarked thereon, which form a part of this specification.

This invention relates to improvements in wrapping machines for wrapping flat, thin articles, such as CHhOS of gum and the like, and the invention refers more specifically to improvements in the mechanism for folding the wrappers about the articles and also to a mechanism for bunching or grouping the wrapped articles preparatory to applying confining bands to the same.

Among the objects of the invention is to simplify the construction and arrangement of the wrapping mechanism, to reduce the number of parts thereof and to increase the capacity of said mechanism.

A further object oi the invention .is to provide an exceedingly simple and effective grouping or bnnching mechanism arranged to receive wrapped gums from the wrapping mechanism and to group them in bundles of a predetermined number in each handle with the t ee flaps of the wrapper confined between the gums without the necessity of reversing one of the articles of each group.

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

Fig. 10 is an enlarp 'l detail section on line 101O of Fig. t Fig. 11 is an enlarged longitudinal section on the line ]l-'t1 of Fig. i). with the wrapping shaft in plan elevation. Figs. 1'2. 13, 1+ and are enlarged transverse sections on the lines 12-12, LS-13, jl.lli and 15-15 of Fig. 9. Figs. 1c, 17, 18 and 1a illustrate the successive. steps of the wrapping operation of the package.

In the particular embodiment of the invention herein shown there are two wrapping mechanisms operating to deliver wrapped articles to a single grouping mcchanism, the grouping mechanism being arranged betwcen the wrapping mechanisms to receive the wrapped articles as they are discharged from the wrapping mechanism and carry them inwardly to grouping position and to finally discharge the groups.

As shown in the drawings, 10 designates the base plate of the machine supported on the stainlards 11, and 12, 12 designate vertical plates or members which rise from and are attached to the base platelt) and which carry bearings for various movable parts of the machine, as ivill hereinafter appear.

14- des gnates the main driving shaft of the machine which is mounted in bearings 15, 15 carried by the plates 1:2. Said operating shaft is provided at one end with a belt pulley 10 by which it is driven.

17 designates a countershalt arranged at one end of the machine parallel witl the main shaft and mounted in bearings 18, 18 in the frame plates 12. (Fig. 2 The countershait is provided at one end with a gear wheel 57 that meshes with a pinion 56 011 the shaft 51 that is mounted in suitable bearings 5') carried by the frame. The shaft 51 also carries a gear wheel that meshes with an idler gear 20 that in turn meshes with a gear wheel ll carried by the main driving shaft 14. 'lhrongh this train of gears the conntersha'lt is driven from the main shaft.

The articles to be wrapped. such as sticks of gum, are placed in the vertical chute or' hopper that is located centrallv between the two wrapping mechanisms. disposed one at each side ofthe transverse medium line of the machine. Each of the wrapping 1necba nisrns embrace-f magazine 26 in which is contained a compressed bundle of wrappers (1- arranged vertically edgewise. Said wrappers are delivered by the stripper rolls 27, 27 and the feed rolls 29, 29, to wrapper receiving recesses 30, 30, the bottoms of which are formed by the wrapper supporting braekets31. The wrappers thus delivered to the wrapper receiving recesses extend across the feed slots or ways 33, 33 which extend in opposite directions from the bottom of the hopper 25, and through which slots the gums are alternately fed from the lower end of the hopper alternately to the oppositely disposed wrapping mechanisms by means of the reciprocating plunger 35. The said fee-d slot is formed in part between the upper horizontal casting 36, attached by the bracket 37 to the adjacent side plate (Fig. 5) and lower laterally separated plates 38, 38, (Figs. 3 and 5) and in part between the upper members 4:0 and the lower members 41 of the wrapping mechanisms (Fig. The upper members are fastened to and depend from the bottoms of the magazines, and the lower members are formed on the brackets 43 extending laterally from and fastened to the adjacent frame plate 12 (Fig. 4). One of the wrapper stripper rollers 2'? is mounted on the main operating shaft 14 (Fig- 3) and the other wrapper stripper roller is'mounted on a shaft l5 geared to and driven from the main shaft 1%. lhe feed rollers 29 are geared to and driven from the shafts 1e and 25 (Fig. 1).

T. e plunger 35 whichreciprocates through the reed slot and the bottom of the hopper to carry the gums from the hopper alternately to oppositewrapping mechanisms, is carried by the free end of an arm 16 which is iaed to and extends laterally from a horisontal reciprocable shaft 17 arranged beneath and at one side of the feed slot. The outer free end of said arm which carries the plunger is turned upwardly, as shown in Figs. 2 and-3, to bring the end thereof between the lower plates 38 of the slot and the plunger in the plane of said slot. Said shaft 4:? slides in bearings 4:9 attached to the adjacent frame plate 12, (Figs. 2, and 5) and is operated through the medium of a crank carried by the rotative shaft 51. The said crank 50 is connected to the forward end of the shaft 47 by means of a pitman 53 shown in Fig. 1, and is driven from the main driving shaft 14 through the train of gears before described and clearly shown in Fig. 1.

Referring now to the wrapping mechanisms by which the individual articles are separately wrapped, the same are made as follows: Located at each side of the center of the machine is a transverse, horizontal shaft which is mounted to rock in suitable bearings 61 in theframe plates 12. Each shaft has an enlarged outer end 63, best shown in Figs. 9, 10 and 11, which is provided with a longitudinal slot 64 arranged in the plane of the axis of the shaft. The said slots 64 of the wrapper shafts are adapted, when the shafts are rocked to bring the slots in horizontal position, to aline with the feed slot 30, and to receive therein the articles and wrappers forced by the plunger 35. The said enlarged end of each shaft is arranged between the superposed members 40, 1 at its inner side and the laterally separated curved arms of a member 65 at the outer side, thereof. The inner sides 66 of the curved arms and the inner side 67 of the member 40 are curved concentrically withrespect to'the enlarged wrapping end of the shaft (Fig.9). The said slotted wrapper shafts are so arranged with respect to their operating mechanism that when the slot of one shaft is horizontal, and alined with the feed slot 33, the slot of the other shaft is vertical and is alined with the vertical wrapper slot 68 formed between the adjacent members 41 and 65; one of the slots 64: being thus in position to receive an article from the feed slot and its wrapper at "the time the other slot 64 is in position for a wrapped article to be discharged therefrom into the adjacent vertical wrapper slot 68. The said shafts 60 and. their enlarged wrapping ends are rocked in the manner indicated by the arrows on Fig. 3, the extent of the to and fro rocking movement of each shaft being 270 degrees or three'quarters of a circle. The said shafts are thus rocked on their axes by a mechanism made as follows: Each shaft is provided near the wrapping side of the machine with a pinion 70 which meshes with a rocking gear sector 71 that is loosely mounted on a stub shaft 72 carried by the frame plate 12 and provided with a crank arm 73. To the outer ends of the crank arms are pivoted the outer, opposite ends of cam-actuated links 7 5, the inner or adjacent ends of which are formed with yokes 7 6 having elongated slot 77, as shown .in dotted lines in Fig. 1, through which extends the main driving shaft 14. Said yolres ar e located side by side on the shaft 14-, and between two disks 77, fixed to said shafts, provided on their inner faces with closed cam grooves or tracks 78 which are engaged by the roller bearing studs 79 0f the yokes 76.

From an inspection of Fig. 3, it will be observed that the feed plunger 35 has forced an article with its wrapper a into the slot 6-1 of the enlarged end of the left hand wrapper shaft, and in so forcing the article into the slot, the wrapper has been folded about the advance margin of the article, as indicated in Fi 9 with the longer upper side a, trailing ehind the rear edge of the article. After the slotted shaft has received the wrapper and article it is rocked threequarters of a turn, or to the position indicated at the right hand side of Fig. 2 and in Fig. 9, with its slot arranged vertically and in line with the wrapper slot 38. \Vhile rocking through the three-quaiters 01 a turn the trailing side a of the 'rapper is confined or guided by the curved inner sides of the member 40 and arms 65. as most clearly indicated in Fig. 9, so as to be in position to be folded in overlapped relation to the other or shorter side of the Wrapper when the arti is forced from the slotted shaft into the folding slot as. The partially wrapped article. which is of a Width but slightly greater than one-half the diameter of the enlarged end of the wrapper shaft. is forced from the slotted shaft into the folding slot 68 by means of a rocking ejector arm 83 iixed to a I Q rock shatt l extending between and mountanother article.

ed in bearings 85 in the frame plates 12. The slotted wrapper shafts are each notched at one side. as indicated at 87, to permit the inner ends of the ejector arms to move downwardly against the upper edges of the partially wrapped articles to eject the latter from the slotted shafts. the said notches being shorter than the slots. The two rock shafts 8+1 associatedwith the two wrapping mechanisms are alternately rocked by means of the cam actuated links or pitzncn 9O pivoted at their outer ends to crank arms 91 keyed or otherwise fixed to the shafts 841 and provided at their inner ends with slotted yokes 92 through which the operating shalt 14 extends. Said yohes .12 are arranged side by side on the shaft ll between disks 93 fixed to said shaft. and the disks are provided with closed cam grooves or tracks 9-1 to rccei re the roller bearing studs 95 carried by the cam yokes as best shown in Fig. The said rock shafts 8i and the ejector arms 83 are actuated alternately. and in opposite directions. one arm being held above the wrap i er shaft while the lattcr is in position to receive an article and its wrapper, as shown at the left hand side of Fig. 3. and the other ejector arm occupying at this time its lowermost position. as indicated at the right hand side of Fig 3. to eject the par tially wrapped article therefrom into the adjacent W sipping slot 68.

The operation of the parts just described serves to completely wrap both sides of the wrapper (6 about the article, as shown in Fig. 1&3. with its end flaps /2''' extending end- Wiseawaytherefrom. l hcpartially wrapped articles are torccd through the slots 38 by the pressure ol the articles which follow and in their passage through said wrapper slots. the cod flaps oi the wrapper are tolded llat against the sidcs oi the package by Folding device made as follows: The width of llic lohling slot is lcss than the length of the partially wrapped articles. so that the nod llaps n oi the. wrappers project beyond he s des of the slots (ll-l at theupper or en .catcd in Figs. 4, 5. 1t) and 11-.

tering ends thereof, as will be made clear from an inspection of Fig. 11. As the partially wrapped article is being forced into the folding slot. the end flaps are creased at their bases 14 by the creasing plates 100 located at the upper ends and at the sides of the wrapper slots. After a Wrapper has beenthus creased. the end flaps are folded backwardly to the dotted line position indicated in Fig. 18 by the radially arranged wings 101 carried by the enlarged ends 68 of the wrapper shaft at the sides of the slots said wings 101 sweeping over the projecting flapsu from the position indicated in Fig. 9 backwardly through three-quarters of a turn in which position the slot of the shaft is alined with the feed slot 213 to receive ll hen another partially wrapped article is received by the slotted shaft. the shaft is turned forwardly threequarters of a rm'olution to deliver the partially wrapped article to the vertical wrapper slot (38. and during such partial rotation the wings 101 swccp back over the end flaps ol' the wrappcr to rcvcrscly fold them to thc position shown in Fig. 12 betwecn said wings and thc crcascr plates 100. The folding of the end llups thus backwardly and il orwardly has the cll'ectto more cil'cctivcly hl lfilk the wrappers at the bases of the cod flaps so as to obtain a clcan fold. The end llaps a. are foldcd against the sides of the package. as the articles are forced through the wrapper slot 38. by means of the folding horns 105. ll); arranged one ntcach side of each slot and form d integral with the members -11. as most clearly indi- The upper ends of said horns arc arranged laterally outside the crcascr plates (),bctwcen which and the wings 101 the flaps (1F ofthc wrappers are confined in their first or upper position. shown in Figs. 9. 10 and 12. As each wrapped article is forced downwardly from said position said wings confine thc cud Haps in their right angle positions until said folded cud flaps are brought into engagement with the upper ends ol thc horns 105, or the second position indicatcd in Figs. 1). 10 and 125. The inner faces 10] ol said horns are concavcly and tramwcrsclv curved and are inclined downwardly and inwardly, so that as the end llaps move downwardly tliereover from second position indicated to the third position indicated in said Figs. 9 and 10 and in Fig. 11. the end flaps are gradually turncd inwardly toward the side oi the package and are folded flat against the sides of the pachagc when the articlc reaches the lourth or lowermost position in the wrapper slots (Figs. and 11)). The article is now completely wrapped and is rcadv to be discharged from the folding mechauisufto the grouping mechanism, if the grouping mechanism be employed.

In order that ready access may be had to the wrapper slots 68 to clear the same of improperly wrapped or crushed articles, the

- members 65, constituting the outer walls of said slots, are movable toward and away from the inner members 41. For this purpose said outer members 65 are provided with rigidly ailixed, horizontal, outwardly extending stems which have sliding engagement in sleeves 111 formed on the upper ends of standards 112 at the ends of the machine. Said standards are bolted to and rise from castings 113 that are made integral with the shaft bearings 11 1, 114 for the parallel, horizontal operating shafts 115 of the grouping mechanism, hei'einafter to be described. The stems 110 are formed at their outer ends with axial sockets to receive compression springs 117 and plungers 118, the springs being interposed and compressed between the inner ends of the plungers. and the bottom of the sockets. The plungers 118 are provided at their outerends with radial locking pins 119 which extend outwardly through openings in the hollow ends of the stems 110 and are adapted to engage short arcua-te locking notches 120 near the ends of the sleeves. Said notches open to the outer ends of the sleeves through releasing slots 121. When the locking plungers are pressed inwardly and are rotated to engage the locking pins 119 with the notches 120 of the sleeves 111, the springs 117 are compressed and act on the stems 110 to hold the wrapper slot members 65 in their innermost or normal positions. To release the locking devices to move the members 65 outwardly, so as to gain access to the material in the wrapper slots 68, the plunger-s 118 are rotated to bring the locking pins in line with the releasing slots 121. The said wrapper slot members 65 are provided at their upper ends with the hood like guide flanges 122 which engage over the inner ends of the sleeves 111, and the members 65are furthcr-provided at their lower ends with outturned guidelugs 121- (shown in full lines in Fig. 3 andip dotted lines in Fig. 2) which engage the guide slots 125 in the bearing basting 113, whereby said members are guided in their movement toward and from the fixed inner members -11 of the wrapper slots.

The wrapped articles or packages are delivered from the t\\ o wrapping mechanisms just described to a common grouping or bunching mechanism by which they are carried inwardly to a centrally located grouping space, wherein they are arranged in groups or bunches of a predetermined number, and the bunches are discharged, from the machine. The mechanism for grouping the packages embraces features of novelty, and the illustrated embodiment of this feature of the invention is made as follows:

The operating shafts 115 of the grouping mechanism, before referred to, are parallel and arranged in the same horizontal plane.

The shafts are provided beneath the wrapping mechanisms with the'sleeves 128, 1:28 formed with deep spiral threads and inter vening grooves, constituting parallel screws 130, which extend at their outer ends beneath the lower ends of the wrapper slots 68, as most clearly shown in Fig. The threads of each shaft are divided into two sections, one of right hand pitch and the other of left hand pitch, and said sections are spaced at the centers of the screws by spaces 131 at the smooth or unthreaded portions of the sleeves, located at the central grouping space before referred to. The parallel, opposing sections at each side of the grouping space or position are formed, one with a right hand thread and the other with a left hand thread, and the shafts are rotated in opposite directions, so that the packages which are deposited in the spiral grooves at the outer ends of opposing sections are carried inwardly, in parallel re lation, toward the grouping space by the rotation of said screws. The outer wrapper slot members 65-extend at their lower ends below the bottoms of the spiral grooves of the screws, as shown in Fig. 3, so as to properly deliver the packages to said grooves. Two parallel screws thus arranged are employed so as to support the packages at both ends, (Figs. 41, 5 and 6) and thereby properly balance the same as they are moved inwardly toward the grouping space. A single screw at each side of the grouping space will obviously effect the inward travel of the packages to group the same if said packages be properly guided and balanced. The arrangement shown is advantageous when operating on oblong packages. Guide rails 13:2, 132, supported at their outer ends on lugs 133 extending upwardly from the bearings 111 of the shafts 115,,and supported at their inner ends adjacent to the grouping space on the upper ends of the standards 13%, 131 of frame 135, are arranged above the grouping screws in such relation to the ends of the packages as to prevent the packages from moving endwise out of their proper positions on the screws. The packages are supported in the grouping position by the uuthreaded portions of the screw-threaded sleeves at the spaces 131 on. the fixed support or platform 13? arranged between the parallel shafts and supported by the central upright standard 138 of the frame 135. Said platform 137 is elongated in the direction of travel of the packages and is curved downwardly at its ends below the bottoms of the spiral. grooves of the screws so as to facilitate the passage of the packages there on. The packages, while being formed in roup. are thus supported at their central ts on the said platform 13? and at their on the smooth or untlu-eaded portions the sleeves 1-35. In order to hold the ges vertically cdgewise during the foron of a group they are delivered by screws into the grouping space against mg arms 138. 138 which are attached their rear ends to :1 lug 139 that rises from the frame 135, said spring arms exforwardly through the grouping space. h'aid spring arms tend to spread from each other at their outer ends so i hold the packages yieldingly between the same and the inner ends of the grouping c ms. The spring arms not only hold the kages vertically on edge, but also holds tho end laps ot the package flat againstthe package during the formation of the groups. a grouping-screw operating shafts 115 geared together by the gear wheels 140.; in feed to the ends of the shafts at one end a machine and are driven from the s .a ft- 17 through the idler gear wheel the gear wheel 142 on the shaft 143. l shaft is arranged at right angles to the snaft 17 and driven through the lathrongh the beveled pinions 141, 111 on c -l shafts (Figs. 1 and '2).

is mounted in bearings at the upper ends of standards 145. 145 fixed to and rising from the base plate 10.

The machine herein shown is designed to form groups having five wrapped packages n each group. and is provided with means for ejecting each group from the grouping anism as soon as the group is formed. .is the mechanism shown is arranged each group is composed of three articles from one pair of parallel grouping screws and tv o puck-l delivered from the other pair; w .1 the spirals of the screws on opposite has of the grouping space are so adjusted If each p. of opposing parallel screws :ilte nately deliver two packages and three 1 we to the grouping space during the erm of forming the group. The packages are delivered from the wrapper slots 68 to the spiral rooves at the ends of the screws the sides against which theend flaps are folded facing inwardly or toward the ouping space of the mechanism. It will be evident that each package is delivdirectly to the group of which it forms ...-t. with the end flaps of its wrapper on side thereof toward the center of the oup. so that there arises no necessityfor or reversing one of the packages of eacn group in order that the end flaps of the packages shall be confined between the packages of the group.

The packages are discharged or ejected from the grouping space by an ejector Inechanisn'i made as follows: 146 designates an reciproca'ble plunger arranged Said shaft 143 transversely of the machine in line with and slightly above the level of the grouping space. h'aid plunger is guided at its forward end in a bearing 147 carried by the adjacent frame plate 12. The plunger is carried at its rear end by a sliding head 148 which is guided in and supported by a grooved, horizontally arranged bracket 1-19 extending laterally from the other frame plate 12 of the machine. The said head is reciprocated in the grooved supporting bracket 149 by means of a crank 150 (Figs. 1 and 7) connected at its outer end to a downwardly extending arm 151 of said head by a link 1432. The said crank 150 is fixed to one end of the shaft 143 driven from the countershaft. as before described, and best shown in Figs. 1 and 2. The plunger 116 is forked at its outer end. and pivoted between the arms thereof by means of the pin 160 is a swinging dog 161. the lower widened and 162 of which is in the path of the group of packages formed in the grouping space. In the forward stroke of the plunger the lower or contact end 162 of said dog engages the group of packages in the grouping space to eject them therefrom into and through the chute 163, through which the group may be delivered to abanding mechanism or other suitable place for the disposal of the group. The swinging dog engages a stop pin 104 above and in front of its pivot 1 which limits the backward swing of the lower contact end thereof when the plunger moves forwardly and holds the dog in proper vertical position during the forward stroke of the ejector plunger. During the backward stroke of the plunger the engagement of the widened. contact end 162 with the forming group swings the dog upwardly to permit it to freely pass over said forming group. The said swinging dog is brought to its upright or operative position when the plunger reaches the limit of" its back stroke by engagement of the upper end thereof with a fixed arm 166 that is attached to the plunger bearing H7 and extends outwardly therefrom toward the grouping space, as most clei rly shown in Fig.
