INVENTOR 1Q J. Fa bey 7:; :7:21- A BY 10M A ORNEY United States Patent C) 3,198,091 SET UP MAQHHQE EUR EGG QARTNS Richard Fahey, Glenview, iii., assigner to Michigan Carton Company, Bettie Creek, Mich., a corporation of Michigan Filled May 2S, i962, Ser. No. 195,3;4-4 25 Ciaims. (Ci. @v3-437) This invention relates to a method and apparatus for setting-up or erecting pape-rboard cartons and, in particular, relates to a method and apparatus for setting-up or erecting a collapsed paperboard carton blank into a cellular car-ton of the type used for receiving and storing eggs.

It has heretofore been proposed to set-up or erect carton-s, such as cellular egg cartons, by providing an apparatus comprising several set-up instrumentalities for successively acting upon collapsed paperboard carton blanks which are `supplied one at a time from a stack thereof contained in a supply magazine. With specific lreference to the set-up of cartons for receiving and storing a plurality f eggs, such a collapsed carton blank is characterized by a connected series of panel members adapted to be erected into top, side `and bottom wall forming members of the finally set-up carton, and further includes cross partition forming panel members foldable out of the plane of the top wall forming member into interlocking engagement with the bottom wall forming member to form the final-ly set-up or erected carton and the cell structure thereof for receipt of the eggs. The set-up apparatus and methods of the prior art have typically included means for feeding collapsed carton blanks from the aforementioned supply magazine one at a time to a set-up zone in which means are provided for successively at least partially expanding the carton blank and disposing the top wall forming member thereof in engagement with a reciprocable set-up head equipped with a plurality of pivoted folding plates or leaves adapted to engage and fold the cross partition forming panel members out of the plane of the top wall forming member for subsequent interlocking engagement with the bottom wall forming member of the carton blank which is then ltucked into engagement therewith by `a `suitable tucking means. While such prior apparatus and methods have been employed with considerable success, they have presented certain problems which seriously detract from the overall efficiency of the carton set-up or erecting operation, and frequently malfunction in properly erecting egg cartons thereby resulting in considerable waste in paperboard carton blanks, and otherwise.

For example, prior `apparatus of the type in question particularly adapted for setting-up or erecting egg cartons have typically comprised a relatively great number of set-up instrumentalities such .as a feeding mechanism, ar-resting mechanism for a carton blank being fed by the feeding mechanism, mechanism for partially expanding the car-ton blank, mechanism for operating the set-up head :and additional mechanism for operating the pivotal folding plates or leaves carried thereby, mechanism for accomplishing final set-up or erection of the carton blank by tucking the bottom wall forming member thereof into interlocking engagement with the cross partition forming members .and mechanism for ejecting a fully set-up or erected carton fr-om the apparatus, most if not all of such mechanisms or instrumentalities being individually controlled by separate drive means including drive cams, follower rods and linkages and the like. Consequently, it has been necessary to utilize rather elaborate drive and ylinkage systems in connection with such mechanisms or instrumentalities so as to interrelate their individual operating actions to the successive sequence of operations desired to be made in fully erecting a carton from a col- 3,198,091 Patented Aug. 3, 1965 ice lapsed paperboard carton blank. As a result, considerable care must be taken in adjusting and servicing each yof the individual drive mechanisms for each of the setup instrumentalities not only to insure proper operation :of the particular instrumentality involved `in performing its intended function, but also to insure that each `such instrumentality operates in proper timed relationship with respect .to the other instrumentalities.

Furthermore, the magazine structures of such prior art apparatus have included oppositely facing wall means rigidly secured to the apparatus in predetermined spaced relationship to receive collapsed carton blanks or `a stack thereof of a predetermined size. Consequently, on those tocca-sions when it is desired to erect carton blanks of a dimension differing from tho-se of the carton blanks for which the magazine was particularly designed, it has been necessary to adjust the spacing of .the wall means of the original magazine or completely replace the latter to accommodate the stack of carton blanks having the different dimensions. As -a consequence, considerable down time may result during adjustment or replacement of the magazine, thereby detracting from the overall eciency of Ithe apparatus.

In addition, in one known Iapparatus of this type, a plurality of pick-up cleats or fingers are mounted on the leading or feeding edge of a feed mechanism so as to engage in corresponding pick-up openings in the lowermost collapsed carton blank of a stack thereof contained in the aforementioned supply magazine so as to feed Isaid lowermost carton blank from the stack into a set-up zone on the apparatus. However, it frequently happens that one or more of the pick-up lingers or cleats carried by the feed mechanism extends not only int-0 the lowermost carton blank in the stack, but lalso into the blank immediately thereabove, thereby resulting in the feed mechanism attempt-ing, `if not successfully so, to feed two carton blanks to the set-up instrumentalities in the set-up zone. Such a situation is intolerable in an apparatus of the type in question, and merely results in waste in the carton blanks since the set-up instrumentalities are incapable of acting upon carton blanks fed more than one at a time.

Furthermore, in addition to pick-up of the lowermost carton blank in the stack thereof in the magazine, it is quite important that the lowermost canton blank be positioned properly for cooperating engagement between the pick-up openins therein Iand the pick-up cleat-s -or fingers on the feed mechanism of the prior art. However, it happens that a given car-ton blank may become misaligned relative to the feed mechanism o-f the prior art as the blank descends in the stack in the magazine, resulting in failure to feed such carton blank and further waste.

In addition, in known apparatus of the type in question, the feed mechanism is additionally equipped with a plurality of ejecting fingers or cleats along the leading or `feeding edge thereof and extending therebeyond, and adapted to engage a portion of an erected carton to eject the latter from the set-up zone of the apparatus as the eed mechanism feeds a successive carton -biank for erection by the set-up apparatus. More specifically, these ejecting fingers or cleats have been adapted to engage with an edge of a locking strip or panel at one end of the carton blank which, upon erection of the carton, is adapted to engage therewith to close the top of the carton and enclose the eggs therein. It sometimes happens that a certain amount Vof warpage occurs along the aforementioned edge of the locking strip or panel causing the edge thereof to be bowed upwardly from the path of the feed mechanism equipped with the ejectin-g lingers or cleats, thereby frequently resulting in the ejecting fingers or cleats being unable to reach the aforef r A y entionedfe-dge of the locking strip or panel to per-form the ejeoting operation.

By way of further example, one ofthe more serious problemsl presented lby apparatus of the type in question and heretofore known resides in operation of the aforementioned set-up head and .the pivotal folding plates or leaves carried thereby for folding the cross partition forming panel members of the V,carton blank into position for interlocking *engagement with the bottom wallY forming member of the carton Vupon nal set-up. More specically, in one type of knownapparatus, the set-up head has .been mounted for oscillatory movement between the supply magazine containingthe stack of collapsed feeding'the carton blanks one at Va'time from a stack contained in a magazine, and which means eliminates the Vpaperboard carton blank` characterized by an improved means for ejecting a fullyiset-up or erected carton from Y the apparatus without requiring `the ejecting cleats or carton .blanks and a set-up zone in which the set-upop- Y eration occurs, and the folding plates or; leaves have been relaitvely impositively actuatedgthat is, as a function of the oscillatory movement of the set-up head itself and without any direct or positive relation tothe position of the car-ton blank being Yset-up or other set-up y instrumentalities of the apparatus,V Thus, it frequentlyl vhappens that the fodlingplates areV partially operated and pivoted before theyeven engage theV cross partition A Y forming panel members of a partially erected carton, thereby resulting inthe folding plates or leavesV attemptv ing to pierce throng-bathe cross pantition forming members rather than folding them into lposition for operative engagement with the bottom wall forming member of the carton '.blank; It was a recognition of these and other fingers of the prior arton the feed mechanism, and

which improved ejecting mechanism is operable irrespective'of any warpage which might occur in any 'part of the fully erected carton, and particularly that part engageable with the improved ejeicting mechanism.

, VIt is a further object and feature of this invention to provide an adapter 'means for a supply magazine of the type comprisingoppositely iixedly spaced wall means for receiving stacks of collapsed carton blanks go-f'two differerent dimensions therebetween, and characterized by the fact that the adapter means includes an adapter member adjustablymountcd on oneV of the lwallrmeans of the magazine .and provided with two carton blank-engaging surfaces selectively disposable'within the magazine to varying extents to provide support for stacksof collapsed problems in'this art that led to the conception and de- I' v-elopment of the presentfinvention.

Therefore, the objects and features of the.A present invention include the provision of animproved set-upy ap-v para-tus and method Yby, which successive collapsed paper'- board carton blanks .maybe fed one at a time from a magazine and set-up `quite rapidly and efficiently into erected cellular cartons ofthe type Vparticularly adapted t-o receive eggs, while avoiding one or more ofthe 'prob'-A lcm-s discussed above as well as others.

FIGURE 13 is a perspective view of one type of collapsed paper-board carton blank adapted to Ibe setup into an erected carton by t-he apparatus and method of this invention.

In FIGURE 13, the numeral generally designates a type of collapsed partially folded paperboard carton blank which is adapted to be manipulated and set-up into an erected summit type carton for subsequent use; that is, a carton blank of the type which, when fully erected, pro- Vides la summit or medial row of partitions between the fron-t yand rear side walls thereof to provide additional support vfor the cover forming portion of the fully erected carton when locked into position in the carton to enclose eggs therein. As is well known in the art, a carton blank of this type is formed from a unitary paperboard blank which is cut, creased, folded and glued so as to result in the collapsed carton blank illustrated in FIGURE 13, which also illustrates the condition of the carton blank as it is supplied to the user thereof. However, as will also `be appreciated by tho-se acquainted with this art, carton blanks other than those specifically designed for the erection of summit type cartons may likewise be employed in accordance with the invention, 4as will become more readily apparent hereinafter.

More specifically, and referring particularly to FIG- URES 8 and 13, the carton blank 20 comprises a relatively narrow locking panel or strip 22 extending across one end of the blank from which the carton blank is formed, and includes a plurality of spaced locking hooks 24 along its free edge. The locking panel or strip is bendable along the fold line 26 with respect to a cover forming panel member 28 adapted to close the top of an erected carton upon -engaging the locking hooks in one edge thereof. The cover forming panel member is bendable yalong a fold line 30 with respect to one side wall forming panel member 32 which is benda'ble along the Ifold line 34 with respect to one bottom wall forming panel member 36 which is, in turn, bendable with respect to another substantially duplicate bottom wall forming panel member 38 along the medial fold line 40. The other bottom wall forming panel member 38 is, in turn, bendable along a fold line 42 with respect to the other side wall forming panel member 44 which is substantially a duplicate of the side wall forming panel member 32. A pair of top wall forming panel members are indicated generally at 46 and 4S in FIGURE 13, and are joined together -by the medial fold line Sti. Referring particularly to FIGURE 13, each top wall forming panel member includes a plurality of interconnected cross partition forming

panel members

52 and 54 which are separable along the score lines 56 by a folding means to be hereinafter described, and are foldable out of the respective planes of the top wall forming

panel members

46 and 48 inwardly of a partially erected carton for subsequent engagement with the bottom wall forming

panel members

36 and 38.

To this end, one end of each of the cross partition forming

panel members

52 and 54 is swingably connected to one edge of the `side wall forming panel member 44 by means of small tabs jointed on fold lines indicated at 5S, while the other ends of the cross partition forming panel members are similarly swingably connected to an elongate erminal glue strip 6i) attached by glue or other adhesive tao the inner surface of the side Wall forming panel mem- A row of spaced elongate openings including hook members 62 extend along the respective bott-om wall forming panel members 35 and 38 in opposition to each other, and are adapted to be tucked inwardly of a `carton during erection er set-up thereof for engagement with a plurality of locking apertures including bridging members e4 spaced along the medial fold line Si) between the top wall forming

panel members

46 and 48. Additionally, upon folding or swinging the cross partition forming

panel members

52 and 54 out of the plane of the top wall forming panel members inwardly of the carton during the erection of the latter, the terminal ends of the cross partition forming members 52 are adapted to be received witl1- in a plural-ity of spaced locking slits 66 formed in the bottom wall for-

ming panel members

36 and 38. Furthermore, and as will be readily apparent, a plurality of spaced tongues 68 project from the medial fold line 4t) separating the bottom wall forming panel members 36 and 3S and, after the bottom wall forming panel members are tucked inwardly of the carton as aforementioned, will eX- tend between respective pairs of the cross partition forming

panel members

52 and 54 to form therewith a crown or summit support for the cover forming panel member 28 foldable thereover to enclose eggs within the carton.

As is clearly indicated in FlGURE 13, in its collapsed or knocked down condition, the carton blank 2@ is partially folded upon itself along the medial fold line 4() at one end thereof and again at the medial fold line Si) to permit securing the terminal glue strip 6d to the side wall forming member 32. As a result, the respective side, bottom and top wall forming panel members including the cross partition forming panel members aforementioned overlie each other and form a double ply thickness of the carton blank material extending from one end thereof through somewhat more than one-half of its length, the cover forming panel member 2S and locking panel or strip 22 being, therefore, of single ply. A plurality of collapsed cartons as illustrated in FIGURE 13 and suggested by FGURE l are adapted to be stacked one upon the other in a supply magazine with the cover forming panel member 28 and the panel members connecterl thereto lying on top, and the edge of the carton blank at the medial fold line 4i) forming the leading edge of a carton blank fed from the magazine.

Referring now particularly to FlGURES l through 3, the drawings illustrate an apparatus comprising a supporting frame indicated generally at 70 which includes four rectangularly spaced support legs 72 supporting a lower rectangular frame structure comprising end rails 74 and 76 and side rails 78 and Si) all of which are rigidly interconnected. Two spaced end posts and 34 extend substantially vertically upwardly from the corners of the aforementioned lower frame structure at one end thereof, and another pair of upwardly and outwardly extending end posts 86 and 88 are rigidly secured to and extend from the other end of said lower frame structure.

An upper vrectangular frame structure comprises the spaced end rails 93 and 1419 extending between andV rigidly connected to the

posts

36, 88 and 82, 84, respectively, and the side rails 162 and 1414 rigidly secured to and extending between the posts S2, S6 and 84, 3S, respectively. f

A bushing 111i is rotatably adjustably v mounted on the shaft 168, and supports a hanger plate 112 to which the motor 114 is suitably secured, it being understood that a hanger rod or other suitable means well known in the art andV not shown may be employed to adjust the position of the motor on the supporting frame 7), The output shaft of the motor drives a pulley 116 and, through a belt 118, a larger diameter pulley v120 secured to drive shaft 122 rotatably journaled in bearings 124 mounted on the side rails 92 and 9dof the intermediate frame structure. A small gear 126 at one end of the'drive shaft 122 drives a larger gear 128 rigidly secured to camy shaft 13@ extending between and `having suitable aperture 'ina bracket 163 kmounted between the ends of the: end railt76 of the lower framestructure. A pair of adjustable collarsY indicated at ll'il are mounted on the Vrod k166 and embrace the bracket 168 to hold their delivery chute in any desired inclined position. A

v pair of upstanding retaining clips 172 are provided at the lower end ofthe delivery chute to prevent erected cartons from falling' out of'such end of the chute.

A substantially YU-shapecl guide chute including the upstanding side ,walls 174 and inclined end wall 176 is mounted on side rails 92 andA 94 of the intermediate frame structt'ucv by ,means of the brackets 173. This inclined guidel chute delivers directly into the lower end of the delivery chutev 160 as indicatedy particularly in FIGURE l, a pair of spaced springjclips 18d-each having one end secured to an upper portion of the end wall 176 of the guide chute and projecting outwardly therefrom further Vlower end `of the'delivery chute, and picked up and moved therealong by the clips 15%,carrie'd by the conveyor chain 156 to the upper discharge endof the delivery chute. A supply magazine for a ,stack of carton blanks in the collapsed condition ofy FIGURE '13 is indicated generally at 132 in lFIGURl-SlY and, referring additionally to FIG- `URES 2, l1 and 12,` comprisesr a first pair of angle Viron structure alongside the driveV shaft'122, `A pair of iden- .i

tical drive cams 131i are respectively suitably secured to the opposite ends of the cam shaft` 130 just outwardly. of the side rails 92 and 94 of the intermediate frame structure.

lt will be noted that drive fromA the drive shaft'122 to theV gear 126 is through a conventional one-way clutch mechanism indicated generally at 136 in FIGURE 3 and of the 'type typically including two members rotatable relative to each other in one direction only, one'of the members including a pin 13% adapted to be dogged with one end of a latch lever 141,0 rotatably supported on'one end of a bracket 142 having its other end rigidlyy securedv to the endl rail HB of the intermediate frame structure;

The latch leverV 174i) .normally needs norattention during 1 operation of theapparatus hereindisclosed, and Vnormally dogs with'theV pin 13S to permitdrive' of the mecha-v nismin only one direction; that is, the direction desired to operate the various set-up instrumentalities 'of the apparatus while, at thersame time, permitting `undogging of the pin for manualV operation of the drive in a reverse fashion for maintenance or trouble shooting purposes, for example.` .n l

A drive sprocket 144 is suitably rigidly connected to the rotatable cam shaft 13) and is connected through a drive chain 146 to another drive sprocket 148 'xed to a bushing '15iirotatably supported on a fixed shaft 152 t of the lower framev structure. Another drive` sprocket posts 18V-4 anda secondpairgof ranglegiron posts 185 rigidly secured to the supporting frame of the apparatus in' rectangularly spaced relationship as by means of `the constitute oppositcly spaced `and iixed wall means of the supply magazine to receive the collapsed carton blanks.V

YA pair of laterally spaced elongate floor ,plates `190 each 154 is also secured to the bushing 150 andrmounts a con-V veyor' drive chain 15d having clipslSS secured in spaced relation thereal'ong for transporting cartons up a delivery chute 16%. The conveyor chain 156 is entrained labout another sprocket, not shown, at the other end of the dei livery chute in a manner well known' toY those acquainted with this art, the upper run of the conveyor chain 1756 riding ina central recessed opening 162 inthe delivery chute. l

The delivery chute 161) is rotatably adjustably supported on the fixed shaft 152 by means of a pair of brackets pivotally'connected to the upper end ofthe delivery chute have one end rigidly secured'to the end raill 1Gb of the upper frame structure of the supporting frame, and project therefrom in parallel relationship beneath the maga- Vzine anglel iron postss18j6 toward the angle iron posts 1S4so asto 'terminates generally midway therebetween and therebelow to form a' door means for-the magazine.

A carton blank support bar 192 extends between and is 'suitably rigidly secured'V to ythe magazine langle iron posts 184, and is providedl with a plurality of laterally spaced carton blankf support 4fingers 194, herein shown 'to beV seven in number, projectingV inwardly of the magazine. The upper surfaces of'a spaced pair of the support ngersjare recessed as indicated at 195 in FIGUREZ to 1receive a carton blank feeding inger to be hereinafter described. A pair of guide bars'193 are suitably adjustablyy yrnountedion an upper support bar 200 extending between the magazine angle iron postsf184 above the support bar 192, and depend therefrom in suchra manner that their lower terminali ends are aligned with the support lingers having they recesses 196 tol aid and facilitate guiding of the carton blank feeding lingers, to be hereinafter described. As illustrated particularlyrin FIG- URES 7 and 8, amountingfbracket 202 is also secured Y hereinafter.

' rWith particular reference to FIGURES 2 and vll, the

Imagazine construction also includes a pair of retaining arms 2% one end of each of'which is pivotally conrriected as indicated at 2648 to a rearward portion of the respective magazine floor plates 19t). The retaining arms cross each other in scissors fashion, and at their opposite ends mount retaining plates 21) including portions extending above and below the plane of the floor plates k19t). A spring 212 interconnects the lower portions of each of the retaining plates 210, and acts to continuously urge the retaining arms into the position shown in FIG- URE 1l in which the retaining plates extend inwardly of the magazine for engagement with the trailing edge of a lowermost carton blank in the magazine to be fed. Suitable stop means, herein shown to be in the form of adjustable stop bolts 214, a-re connected in the end rail 100 and include head members engageable with the respective retaining arms to limit movement thereof under the inluence of the spring 212 into the magazine for the purpose aforementioned. 4

After loading the supply magazine 182 with a stack of collapsed paperboard carton blanks in the condition illustrated in FIGURE 13, the leading edge of the lowermost carton blank in the stack at the medial fold line 4t) including the tongues 68 will rest upon the support lingers 194 while the trailing edge thereof formed by the locking panel or strip 22 will rest on the floor plates 199 adjacent the magazine angle iron posts 186. At this time, and prior to feeding such carton blank to the seteup instrumentalities to be described hereinafter, the pivotal retaining arms 296 are spread scissors fashion as illustrated in FIGURE 1l so that the upper portions of the retaining plates 210, which extend above the floor plates 190, engage the trailing edge of the carton blank to continuously urge such carton blank into supported engagement on the support fingers. However, means are provided, in conjunction with a carton feeding mechanism to be hereinafter described, for collapsing the retaining arms 2li-5 outwardly of the magazine to the position illustrated in FIGURE 2 to free the trailing edge of the carton blank for movement to the right in FIGURE 2 to facilitate disengagement of the leading edge thereof from the support fingers 194, whereby the lowermost carton blank will drop entirely onto the floor plates 1911 for subsequent feeding to the set-up instrumentalities.

' Referring now particularly to FIGURES 1, 11 and l2, the magazine construction also includes means for adapting the magazine to hold and supply collapsed paperboard carton blanks having different dimensions or lengths between the leading and trailing edges thereof. More specifically, the lower end of each of the magazine angle iron posts 186 includes a recess 216 to receive an adapter member indicated generally at 21S. Each of these adapter members includes a pair of substantially parallel oppositely disposed carton blank-engaging

surfaces

220 and 222, there also being provided a guide surface 224 tapering from one end of the surface 22! and a guide surface 226 tapering from the other end of the other surface 222. A hinge pin 228 is adapted to be suitably secured to each of the magazine angle iron posts 186, and rotatably and slidably receives a respective one of the adapter members 218 on an axis closer to one of the carton blank-engaging surfaces than the other. A spring 239 acting between one side surface of each adapter member and the head of its associated hinge pin continuously biases the respective adapter members toward the respective magazine angle iron posts. A pair of stop pins 232 are mounted on the opposite side surface of each adapter member above and below and in the same common plane as the hinge pins 223 for abutment with a surface of the respective magazine angle iron posts 186. Thus, the stop pins 232 prevent rotation of the adapter members on the respective hinge pins while in the position of FIGURE l2, but the adapter members may be slid against the opposition of the spring 23@ to free the stop pins from abutting engagement with the magazine angle iron posts thereby permitting the adapter members to be rotated 189 and then replaced in the position il-y lustrated in FIGURE l2 to select one or the other of the carton blank-engaging surfaces 22) and 222 for projection into the magazine. Since the carton blankengaging su-rfaces are located at different distances from the axis of the hinge pins 228, it will be immediately apparent that any one given adapter member will per mit adjustment of the effective carton blank-receiving length between the magazine angle iron posts 184 and 186 to receive carton blanks having two different dimensions between the leading and trailing edges thereof. irrespective of which carton blank-engaging surface is selected in accordance with the particular carton blanks being fed, it will be readily apparent that each such surface is provided with the aforementioned guide surfaces to facilitate feeding carton blanks as they descend in the stack in the magazine into position on the floor plates 190 and support lingers 194. Needless, perhaps, to mention, it will also be apparent that more than two sizes of carton blanks can be handled by the magazine merely by providing more adapter members of corresponding configuration.

With particular reference to FIGURES 1, 2, 9 and 10, a folding head is indicated generally at 234 and a set-up and feeding head is indicated generally at 236. The folding head 234 comprises a laterally elongate carriage plate 238 extending between the side rails 102 and 104i of the upper frame structure of the supporting frame, and has suitably rigidly secured to the opposite ends thereof the guide bushings 2451 which are respectively slidably mounted on a pair of guide rods 242, each of which has one end rigidly secured to the end rail of the upper frame structure and the other end thereof secured to a bracket 244 rigidly secured to and depending from the

side rail members

162 and 104 of the upper frame structure between the ends of the latter. A generally rectangularly shaped open folding frame 246 has the upper portion thereof secured to the carriage plate 238 and depends therefrom. The upper and lower portions of the folding frame are provided with a suitable number of vertically aligned pairs of folding arms 248, herein shown to be eight pairs in accordance with the number of cross partition forming panel members to be folded on the carton blank in question, each arm having one end suitably rigidly secured to an upper or lower portion 0f the fold ing frame so as to project away therefrom. The other end of each of these folding arms is arcuately curved as illustrated particularly in FIGURE 9 to facilitate the folding operation on the cross partition forming panel members. Additionally, each of the folding arms is provided with a locking linger 2@ suitably rigidly secured to one side surface thereof and projecting laterally therefrom so as to receive and hold one edge of a folded cross partition forming panel member to facilitate final erection of a carton as will become more apparent hereinafter. In view of the foregoing description, it should be immediately apparent that the folding head 234 comprising carriage plate 238 and folding frame 24d is mounted for rectilinear reciprocation along supporting frame 70 by means of guide bushings 240 and guide rods 242, power for such reciprocable movement being provided by a drive means to be described hereinafter.

At this juncture, it should be noted that the carriage plate 238 is mounted immediately below the magazine floor plates 199 and, as aforementioned, the folding frame 246 depends from the Carriage plate and hence below the floor plates 190 as clearly illustrated in the drawings. Furthermore, the central portion of the carriage plate, and particularly the edge 252 thereof as illustrated particularly in FIGURE 9, is adapted to engage the lower portions -of the retaining plates 210 on retaining arms 206 aforedescribed to collapse them to the position of FIGURE 2 for feeding a carton blank from the support fingers 194 upon the carriage plate and entire folding head being reciprocated to the positionV illustrated in FIGURES V1 and 2.

The set-up and feedinghea-d 236 comprises a'generally being aligned and positioned relative to thefolding arms of the folding frame to permit passage of the latter.y there- 'around as indicated particularly in FIGURE l0. Each end of theset-up and feeding frame 254 is suitably rigidly secured to a guide rod 258 which are respectively slidably mounted within guide bushings 250 rigidly secured to the carriage plate 238 and beneath the latter; The other ends of each of these guide ro-ds are suitablyrigidly secured to a generally vU-shaped cross bar 262 having stop members 2d4 at opposite ends thereofv adapted to abut thel end posts 82 and 84 to limit travel of the set-up and feeding head in this direction under the influence of the drive means to be described. Thus, the set-up and'feeding frame 254 is located in front of the `folding frame 246,

and the upper edge thereof is provided with a plurality of feeding. blades or fingers 266, herein shown to be six in numbenall of which project forwardly and upwardly from the upper edge of the set-up and feeding framey above the surface of the magazine floor plates 190, the narrower extreme outer feeding blades or fingers .being inclined upwardlyto a somewhaty greater extent than the interior wider fingers or blades.l Four rectangularlyv spaced stop members 258 are located in theY respective four corners of the set-up Vand feeding frame 254 for abutment with the corresponding `corners of the folding frame 24e-as will appear hereinafter. n

A pair of brackets 270 yextend between the upper and lower portions of the set-up and feeding frame 254, and

set-up and feeding ead tothe position shown in FIG- URE 1. l Y Y AReferring particularly to` FIGURES 1 and 2, a bottom tuckingplate or blade 288 extends transversely between and below the side rails 102 and 104 of the upper Aframe structure of the supporting frame soV as .to be .substantially aligned with the medial portion of the aforedescribed folding head and set-up and feeding head. One Vend of the ing plate or blade is suitablyrigidly secured to a depending portionlof the-cross rail 105 and the other free end thereof extends toward the folding head and set-up and feeding head aforementioned..V rThe freeV end-vof the tucking plate or blade is provided with Ya plurality of elongate openings 2,90 adapted to receive wall formingv panel member of the carton blank. A pair of spaced receptacles 292 are also` suitably secured to the cross rail 105 to receive ,therein cushioning springs l294 for a purpose to appear more fully hereinafter. Additionally,l a suitable number of brackets 296 are spaced along the lower portion of the cross' rail 106 to support springr fingers 298 mounting on the free vends thereof ejectinggnge'rs or cleats 300 to facilitate in ejecting a fully erected carton from the apparatus in a manner to be described.

, Referring particularly to FIGURES 1 andZ, the apparatlkls also includes a second set-up head indicated generally at 302 and comprising4 a laterally elongate setup framev indicated generally at 304 havingits opposite each pivotally mounts aplatch lever 272 adapted to latchl ingly engage and disengage the lower portion of the folding frame 246. Each of the latch levers is continuously biasedv toward such latching'engagement bythe free ends of leaf springs 274 having their lopposite endsl securedto the cross bar 262 of the set-up andfeeding head. v

With Vthe latch levers 272 engaged as illustrated particularly in FIGURESl 1, 4 and 5, the folding head 234 and set-up andrfeeding head236 are adapted to be reciprocated rin unison along the supporting frame 70 from right to left in theaforementioned figures of the drawings by a drive means including the aforedescribed drive cam 134.1 More specifically, and referring particularly to FIGURES 1 through 3, a pair-of drivevarms 276 each have one end suitably pivotally vjournaled. for oscillation on "the fixed shaft 108 and their other ends pivotally connected'through a drive link 278 to a bracket depending from and suitably rigidly secured to the carriage plate 238 of the folding head 234. A cam follower roller 280 is' rotatably mounted on each of the drive, arms 276` for engagement with the respective' drive cams 134.

ends suitablykrigidly secured respectively to a pair of .guide rods 306 which are respectively slidablymounted in guide bushings 308 suitably rigidlysecured to the cross u rail MP6,. the' opposite ends of these guide rods being suitably rigidly secured to the opposite ends of across bar 3130. The cross bar 310 is connected by a pair of return springs 312 to the cross rail 1706 so as to continuously bias the set-up head 302 lto the right and relativeto the tucking plate or blade 288 to a position in a set-up zone on the apparatus as illustrated in FIG- URES 1, Zand 4V through 6. A latchflever 314 is pivotally connectedv to, .a bracket carried by the end Vrail 98 ofthe upper frame structure Vof the supporting frame, and includes a clogging notch 316 engageable` with the cross bar 310 to lock the set-up head 302 in position in tue set-up zone aforementioned. jIn' particular, the latch lever prevents movement 'of set-up head 302 to theleft vrin FIGURES V1 and 2 to an extremek retracted position until released byV mechanism to be described hereinafter.

Furthermore, a pair of feeding fingers 328 are suitably secured to the top portion of the upper wall membe'rp322 of the set-up frame so as to be in vertical alignment with and pass beneath the guide bars v198, and

' enter the recesses 196'in"the.pair,of support fingers 194 l on the magazine forfeeding the leading edge of a carton blank therefrom as will also appear-more fully hereinafter. v'Thelower wall member. 324 of the set-up frame 364B provided with `a suitable number of slots to permit movement therethrough' of 'the' ejecting fingers or cleats v30d. r`Also,a suitable number of spaced retaining fingers 330 lare secured ,to and project outwardly from frame 304. A pair of stop or abutment rods 332 each have one end suitably rigidly secured to the respective end plates 31S of the set-up frame, and project therefrom for cooperation with the set-up and feeding head 236 in a manner to be described hereinafter. Also, a pair of unlatching lingers 334 each have one end xedly secured to the end plates 31S of the set-up frame for cooperation with the latch levers 272 pivotally mounted on the setup and feeding frame 254 to control unlatching thereof.

A pair of bell crank latch levers 336 are pivotally mounted on cross rail 106 adjacent the side rails 102 and 104 of the upper frame structure of the supporting frame and are adapted to selectively engage the end plates 318 of the set-up frame 304 to hold the latter in a retracted position away from the set-up zone of the apparatus as illustrate-d in FIGURE 7, and are selectively disengageable to permit the return springs 312 to return the setup head 302 to the set-up zone or the position illustrated in FlGURES l and 4 through 6. To this end, one end of the respective latch levers 336 is pivotally connected through suitable joint connections in a link 338 to laterally projecting portions of a pair of latch control levers 340 pivotally connected to the side rail members 92 and 94 of the intermediate frame structure of the apparatus.

rThe upper ends of these control levers are interconnected by a cross rod 342 carrying a central bracket 344 mounting an adjustable control member 346 which, as the control levers are oscillated as to be described hereinafter, will operate in timed relation with the rest of the setup instrumentalities to control latching and unlatching engagement of the latch lever 314 with the cross bar 310 of the set-up head 302. Additionally, oscillation of these control levers operating through the links 338 similarly controls latching and unlatching engagement of the bell crank latch levers 336 with the end plates 318 of set-up frame 304. The control levers 340 are operated in accordance with the positions of the drive cams 134, drive arms 276 and the corresponding positions of the various set-up instrumentalities of the apparatus by means of an adjustable cam follower 348 located at the opposite end yof each of the control levers from cross rod 342, and adapted to cooperate with the respective drive arms 276 whereby, upon oscillation of the drive arms counterclockwise in FGURE l, the control levers are rotated clockwise under the influence of springs 350 connecting7 the latter to the cross rail 106 to ultimately lift latch lever 314 and dispose latch levers 335 for latching engagement with set-up frame 304. Conversely, upon clockwise oscillation of the drive arms 226 in FlGURE l, the control levers will pivot counterclockwise to ultimately dispose latch lever 314 in position to re-engage the cross bar 310, and operate the bell crank latch lever to the positions illustrated in FIGURE 2 to release the set-up head 302 from its retracted position for return to the set-up zone of the apparatus under the influence of return springs 312.

Referring now to the operation of the aforedescribed apparatus, it will be understood that the motor 114 is energized to continuously rotatably drive the drive shaft 122 and cam shaft 130. As a result, the drive arms 276 are continuously oscillated about the axis of shaft 108 to reciprocate the folding head 234 in one direction and n then the opposite direction on the supporting frame.

Furthermore, drive is conducted through drive chain 1455 to conveyor Chain 156 to continuously operate the y latter for conveying fully set-up or erected cartons.

14 zone on the apparatus for erection of the same. At this time, the latch lever 314 is engaged with the cross bar 310 of the set-up head 302 to hold the set-up frame 304 at the forward or free end of the tucking plate or blade 283 in the set-up Zone. Furthermore, the latch levers 272, under the iniluence of the leaf springs 274, latchingly engage the folding frame 246 so as to hold the folding head 234 and the set-up and feeding head 236 in predetermined spaced relation as the carriage plate 233 is reciprocated along the guide rods 242 from right to left in FIGURE l of the drawings under the influence of the aforedescribed drive means.

The drive means then operates to move the various set-up instrumentalities to the FIGURE 4 position. In moving from the FGURE l to the FIGURE 4 position, the feeding blades or fingers 266 on the set-up and feeding head 236 engage the medial fold line 50 between the top wall forming

panel members

46 and 48 of the carton blank to feed the latter along the oor plates toward the set-up head 302. The leading edge of the carton blank along the medial fold line 40 between the bottom wall forming panel members thereof will initially engage the upper wall member 322 of the set-up frame 304 and, due to the roughened or frictional surface of the plate members 326 carried thereby, will tend to be retarde-d in yits feeding action toward the apex of the inclined wall members 322 and 324 of the set-up frame. During this feeding action, and prior to reaching the FGURE 4 position, the rearward portion of the double ply portion of the carton blank is confined on the floor plates 190. As a result, due to the retarding action on the leading edge 40 of the carton blank, the bottom wall forming panel members 3d and 33 tend to and do expand somewhat, facilitating further expansion thereof as illustrated in FIGURE 4 after the double ply portion of the carton blank passes over the edges 0f the floor plates 190 and t-he leading edge 40 of the carton blank assumes the position shown.

ln the FIGURE 4 position, the double ply portion of the carton blank has moved completely off of the floor plates 190 of the magazine as aforedescribed, while the cover forming panel member 23 and locking panel or strip 22 thereof still extends to some extent onto the floor plates. At this time, the set-up and feeding head 235 is able, in response to continued reciprocation thereof with folding head 234, to begin further spreading the partially expanded carton blank. Thus, continued movement of the drive mechanism disposes the set-up instrumentalities in the FIGURE 5 position, at which time the carton blank is substantially fully expanded in the set-up zone of the apparatus. In this position, the bottom wall forming

panel members

36 and 38 and top wall forming panel members 46 and 43 including cross partition forming

panel members

52 and 54 are respectively engaged with and confined between the set-up

frames

304 and 254 and interconnect the side wall forming

panel members

32 and 44, the respective side wall forming panel members being guided and confined between the lower surfaces of the support bar 192 on the magazine and the retaining fingers 330 projecting from the lower wall member of the set-up frame 304. In particular, in the FIGURE 5 position, it will be noted that the top wall forming panel members including the cross partition forming panel members lie substantially flush with the set-up and feeding frame 254 for the subsequent folding operation on the cross partition forming panel members as will be described. Also, the ends of stop or abutment rods 332 engage the set-up and feeding frame 236, and unlatching lingers 334 are in position to unlatch the latch levers 272 to free the folding head 234 for reciprocable movement relative to the set-up and feeding head 23d and set-up head 392. Finally, and as shown more clearly in FIGURES 7 and 8, the lower ends of spring clips 204 are interposed between the carton blank and the set-up frame 304.

At this time, the edges of thecross partition forming panel members adjacent the top wall form-VV ing panel members of the carton blank are received between and locked `by therespective folding arms and the lockingiingers 25d carried thereby as indicated in FIGURE 6.

More specifically, during Vreturn movement of theV folding head 234 and set-upand feeding head 236 as described above, these instrumentalities will move from `the FIG- URE`7 position through theFlGURESposition to the The timing of the arms 27d is "such that the .folding vhead 234 and set-up vand feeding head 236 will reach at leastthe position illusf trated in FIGURE 8 before the'bell crank latch meming frame 254 so that further reciprocation of the fold-l Y ing head 234m the left in FIGURE 6 will oflnecessitycarry with it the set-up and feeding head 236 and the set-uphead 362 which is indirect engagementlwith the set-up and feeding head r236` through the stop ror abutment rods 332. j

As they driveY means operates to reciprocate the'gaforedescribed mechanism from the position of FIGURE 4 through the positionfof FIGURE 5.tothe position of FIGURE 6, the drive arms 276 will be oscillating counterclockwise in FIGURE 1 permitting the latch control levers 3ft@ to rotate clockwisel under ythe influencev of the springs as aforedescribed; f As the v c ontrol levers` so rotate, the adjustable control member 346VK gradually rises Vuntil 'it is in a position to engage the free end of the latch lever 314 to undog the notch 316 thereof from the cross bar 314i, of the set-up head 3tl2. Additionally, as the control levers so rotate, the bell crank latch levers 336 are being returned fromthe unlatching position of FIGURE 2 to a position for engagement with the a fully re- Y set-up frame 3de upon the latter reaching with the various set-up instrumentalities inthe positions Y 'illustrated in FIGURE -6. Consequently, further operation of the drive means now Vreciprocates-the folding head bers V336y are released for return movement of the set-up head 302. 4in this manner, the folding head and set-up andfeeding head are permitted torreturn far enough to,

first, clear the trailing edge of the cover forming panel member 23 Vof the fully erectedl carton for free delivery of the latter into the guide rchute to the deliverychute ,and,V secondly, to place the carriage plate 238 in position Y to depress the retaining arms Zeeland retaining plates 210 out of engagement with the lowermost carton blank in the stack which is next tobe fed tothe set-up apparatus.

Thus, upon the folding head and setup and feeding i head reaching approximately the position illustrated in ation .position the set-up zone at the forward edge of the 4tucking-plate or bladeuas illustrated in FGURE 4, move- `ment thereof is arrested and cushioned bythe cushioning .springs 294 engaging cross bar-316, and the feeding iin- ,gers 328 project through and along the recesses 196 in 234, set-up andfeeding head 23e and set-up head 302:rv
