At this time, the bottom flaps of the carrier blank are disposed in alignment with the Side walls. in order to form the carrier and complete the package Iincluding the bottles in the carrier, it is necessary that the bottom flaps be folded beneath the bottles and interlocked with the bottles being tightly clamped within the carrier.
In accordance with this invention, it -is proposed to provide a manually operated packaging machine which will allow an individual to readily and quickly apply a bottle carrier blank to a plurality of bottles and after the blank has been so applied, form and lock the carrier through the operation of a suitable lever.
Another object of this invention is to provide a novel mechanism for folding bottom flaps of a bottle carrier 'beneath a plurality of bottles to be encased within the carrier, the mechanism including two support strips for two rows of bottles and flap folding members movable immediately below the support Strips to swing the bottom flaps of the carrier into position beneath the bottles with edge portions of the bottom flaps being in overlapping relation, the flap folding members being carried by two generally upright supports which are pivotally mounted at their lower ends andwhich have associated therewith a rotatable cam, the single cam being engaged with cam followers associated with the two supports so that as the cam is rotated, the two supports are moved towards each other to swing the flap folding members towards each other and to effect the folding of the iiaps as is required in the closing of the carrier.
Another object of this invention is to provide a novel drive for flap folding members in a bottle carrier forming machine, the drive including a shaft which may be readily manually oscillated and which shaft carries a cam, the flap folding means includ-ing a pair of opposed flap folding members .carried by supports, the cam` being disposed outwardly of and adjacent one of the supports and in engagement with a cam follower directly carried thereby, and the other of the supports having a link which entends across the first-mentioned support and is pro'- vided with a cam follower Whichengages the cam in opposition to the lirst-mentionedcam follower whereby when the shaft is rotated to rotate theV cam, the one support is moved away from the cam and the other support is pulled towards the cam to effect the necessary movemeut of the flap folding members.
Another object of this invention is to provide a novel manually operated packaging machine for usewith `wrap- 3,197,937 Patented Aug. 3, i955 ICC around type bottle carriers wherein a bottle carrier blank is positioned over the tops of a plurality of bottles disposed in two rows, after which the bottles and the bottle carrier blank are moved to a station wherein the bottle carrierblank is formed into the desired bottle carrier and locked together with the bottles to form a convenient package, the -bottles at this time being supported by a pair of support strips about which the bottle carrier is wrapped, and a platform for receiving the package, the platform having a ramp up which the bottom of the bottle carrier rides as the Vbottles move off of the support strips. A further object of this invention is to provide a novel control ramp for use in conjunction with a packaging machine, the control ramp being pivotally mounted and having a stop at the entrance end thereof, the stop being disposed in the path of a package when a completed package is disposed thereon, and the ramp being provided with counterbalance means for swinging the ramp to a position where the stop is depressed to permit a next package to be passed onto the ramp.
Still another object of this invention is to provide in a packaging machine for use with a wrap-around type bottle carrier means for folding bottom flaps of the carrier into overlapped relation and assuring the folding of -one of the bottom flaps in advance of the other, the flap folding means including two flap folding members which are of similar construction but one of which has a portion disposed further inwardly than the corresponding portion of the other so that when the two flap folding members are simultaneously actuated, one of the flaps will be folded in advance of the other lap A still further object of this invention is to provide a novel apparatus for folding bottom flaps of a wrap-around type bottle carrier and for interlocking the overlapped portions of the bottom iiaps by the engagement of locking tabs through openings, the apparatus including a pair of generally upright supports pivotally mounted at the lower ends thereof, each of the supports carrying a flap folding member, a manually rotatable shaft carrying a rst cam engaged with cam followers connected to the supports for effecting `the simultaneous movement of the flap folding members, and one of the flap folding members carrying a pivot shaft to which there is rigidly secured a desired number of arms with each arm carrying a tab posi- 'tioning finger, and there being further connected to the pivot shaftfor rotating the same means operated by a second cani carried by the shaft wherein when the shaft is rotated, the folding of the bottom flaps of the carrier is first effected, after which further rotation of the shaft results 'in the operation of the tab positioning fingers to effect the interlocking of the overlapped por-tions of the bottom flaps.
With the above and other objects in view that will hereinafter appear, the `nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views il- Vand shows the manner in which a nished package is reioved from the bottle support strips, the ramp for dis-V charging iinished packages being shown in a package receiving position.

Referring now to the drawings in detail, it will be seen that there is illustrated the packaging machine which is the subject of this invention, the packaging machine being generally referred to by the numeral 15. The packaging machine I5, as is best shown in FIGURE 7, includes a suitable frame 16 carried by uprights 17 ofthe desired height. The frame 16 has extending upwardly therefrom adjacent the right hand end thereof, as viewed in FIG- URES 1 and 2, a suitable support 1S which has secured thereto a generally horizontal plate 19. The plate 19, which may be continuous transversely of the machine 15, or which may be interrupted, as is shown in FIGURE l, is provided along the outer edges thereof with upstanding flanges 2th Each flange 2li projects to the right of the plate or plates 19 and is provided with a horizontal flange 2l which in effect forms a continuation of the plate 19. It is to be understood that each pair of flanges 20 and 2l combine to define a guide rail, generally referred to by the numeral 22.
A pair of endless chain conveyors 23 extend between the guide rails 22 and have the upper runs thereof terminate short of the plate 19. The endless chain conveyors 23 are suitably supported in a manner not shown and receive and deliver -two rows of bottles B. It is to be lunderstood that the relative elevations of the upper surfaces of the flanges 21 and the upper runs ofthe endless chain conveyor 23 will be such that as the bottles B ride onto the flanges 21 of the guide rails 22, they will be A slightly elevated with respect to the endless chainV conveyor 23 so that there will only be very slight fri/:tional lengagement between the endless chains'23 and the bottles B and the bottles B can remain stationary on the guide rails 22 while the endless chain conveyors 23 move therep 19 in cantilever relation as generally continuations of the endless chain conveyors 23. The support strips 24 extend across a central portion of the packaging machine l5 and serve as the sole supports for a plurality of bottles B and associated carrier blanks 25.
The frame lo is provided with an upstanding support 2o adjacent the left ends of the support strips 24, as is best shown in FIGURES 1 and 2. The upstanding support 2o carries a horizontally disposed platform 27 which is provided at the right end thereof with an upwardly and to the left inclined ramp 2S. The ends of the support strips 24 will normally be supported by the ramp Z.
The platform 27 is relatively wide as compared to the path of movement of packages thereover and outer portions of the platform 27 are provided with'channel crosssectional spacers 29. The spacers 29 support generally triangular cross-sectional folding blades 3@ which are provided withy tapered folding surfaces 5l at the right ends thereof.
The packaging machine l5 also includes take-away means 32 at the left end thereof. The take-away means 32 may be in the form of a conveyor, a table, a ramp, etc., and for purposes of illustration has been shown as a table. The take-away means 32 is disposed below the level of the platform 27 and is spaced therefrom a distance generally equal to the length of a package formed of a plurality of bottles and the carrier wrapped around the bottles.
The packaging machine 1S includes a combined ramp and stop, generally referred to by the numeral 33, which extends between the platform 27 and the package takeaway means 32. The combined ramp and stop includes a pivot shaft 34 which has the opposite ends thereof supported by suitable brackets v35 which, in turn, are supported by the support 26. The combined ramp and stop 33 includes a ramp portion 36 which has the pivot shaft 34 secured to the underside thereof. The stop is in the form of a depending flange 37 on the right end of the ramp 36. A further flange 38 projects to the right from the lower end of the flange 37. The' tapering or pivoting of the ramp 36 downwardly from right to left is limited by engagement of the flange 38 beneath the platform 27, as is shown in FIGURE 2. When the combined ramp and stop 33 is in the position of FIGURE 2, the flange 37 projects up int-o the path of packages and prevents the removal of a completed package from the platform 27. The ramp 36 is held in its position of FIGURE 2 bya package, such as the package P disposed thereon.
The combined ramp and stop 33-is provided with suitable counterbalance means 39, as is shown in FIGURE 1, to effect the automatic pivoting of the ramp 35 when the package P is removed therefrom to the position shown in FIGURE 3. At this time, the stop forming flange 37 is pivoted to a position below the surface of the platform 27 and another package P may be slid from the platform 27 onto the package take-away means 3:2 down the ramp 36. The function of the stop formed by the flange 37 is more important, as will be described in detail hereinafter, than merely preventing a package from sliding down 'the ramp 36.
Reference is again made to FIGURE l in detail, wherein it will be seen that the packaging machine 15 includes a carrier blankapplying station A which generally overlies thev discharge end of the endless chain conveyors 23. The packaging machine I5 also includes a carrier bottom flange folding and locking station C which overlies the support strips 24.
As is best Shown in FIGURES Sand 6, the frame I6 members 44B and 41. The angle member 4th includes a base fiange i2 and an upstanding flange 43. On the other hand, the angle member 4I includes a base flange 44 and an upstanding flange 4S.
A pair of generally opstanding supports #to and 47 are pivotally connected at theirlower ends to the upstanding flanges 43 and 45 of the angle members 4t? and 41, respectively. A pivot pin i8 is provided f-or pivotally mounting each of the supports 46 and 47. i
There are two supports lo and a bottom flap folding member 4S extends between the two supports 46. The bottom flap folding member 48 includes a generally upright flange l? and a base flange 5d. There are` also two of the supports 4,7, and the upper ends of the supports 47 are connected together by a bottom flap folding lmember 5l which includes a horizontal flange 52 and an upright flange 53. At this time, it is pointed out that the free edge of the ange Sti is disposed closer to the center line of the machine than is the free edge of the flange 52 for a reason to be described in detail hereinafter. Y
The angle members iti and 41 carry upstanding bearing units 54 which are secured to the upstanding flanges of the angle members lil and 41 by means of bolts 55. The bearing units 54 are properly spaced by means of spacers 5o. Actuating shaft 57 is rotatably journaledl in the bearing units 5d and extends parallel of the machine i5 adjacent the supports 47. It is to be understood that during the use of the machine 15, the shaft 57 is oscillated back and forth.
A cam` 53 is carried by the shaft 57 for rotation therewith adjacent each of the supports 47. The shape of the cams 55 is best shown in FlGURE 1l. generally rectangular in outline and includes two flat sides 59 connected by a pair of rounded ends 60.
The supports 47 are provided with cam followers o1 which are engaged with the inwardly facing portions of the cams 53. On the other hand, the supports 46 have pivotally connected thereto horizontally disposed links r2; which are connected to the supports 46 by means of pivot pins d3. Each link 62 has a horizontally elongated slot ed therethrough (see FGURE 7) through which the shaft 57 passes. The end of each link 62 remote from its associated support 46 is provided with a cam follower o5 which engages its respective cam 58 on the outer surface thereof in opposition to the associated cam follower nl.
It is to be noted that the cam followers o1 and 65 normally engage the flat sides 59 of the cams 5S. However, when the cams 58 are rotated through` the rotation of the shaft 57, the cam followers 61 and 65 are urged apart. As a result, the supports 47 are swung to the left and the supports 46 are pulled to the right, as viewed in FGURE 7. The supports 45 and 47 move in unison. The movement of the supports de and 47 continues until such time as the cam followers 61 and 65 ride up onto the rounded end portion 60 of the cam 5S, at which time, further movement of the supports 46 and 47 is eliminated.
it is to be noted tha the supports 46 and 47 are normally urged apart by means of springs 66. Each spring extends from a pin o7 on a respective link o2 to a pin 63 on a respective support 47.
The supports 47 have a pivot shaft 69 extending through the upper portions thereof. The pivot shaft 69 is rotatable and is maintained in place with respect to the supports 47 by means of collars 7i) mounted on opposite ends thereof.
A pair of arms 71 are rigidly secured to intermediate portions of the pivot shaft 69. Each arm 71 adjustably carries a finger 72 which has a lower end threaded into its respective arm 71 and which is locked in an adjusted position by means of a lock nut '73. The purpose of the finger 72 will be described in detail hereinafter. The arms 71 are normally held in retracted positions by means of springs 74 which extend between the pins 67 and pins 75 on the arms 71.
A lever 7u is rigidly secured to an intermediate portion of the pivot shaft o9. The lever 76 is, in turn, connected to the upper end of a link 77 by means of a pivot pin 78. A lower portion of the link 77 is provided with an elongated slot 79 which extends longitudinally of the link 77 Each cam 5S is 6 and receives the shaft 57, the shaft 57 serving to guide the link 77 in its movement.
A cam Sil is carried bythe shaft 57 adjacent the link 77. The lower end of the link 77 is provided with a cam follower 81 which engages beneath the cam S@ so that when the shaft 57 rotates, the cam Si) acts on the cam follower 81 to move the link 77 downwardly and urge the arms 71 and the lingers 72 upwardly from their positions shown "in FGURE 7 to the positions shown in FGURE 8. rlhe shape of the cam t? is best shown in FGURE 8, and it is to be noted that the cam is so positioned relative to the cams 5S that for all practical purposes the fingers 72 do not move upwardly until after the bottom llap folding members 48' and 51 have folded the bottom flaps of the carrier beneath the bottles.
At this time, it is pointed out that each of the bottom flap folding members 43 and 5l is provided at the opposite ends thereof with suitable alignment lingers $2 to edect the `alignment of the rilap folding members 4S and 51 with the carrier blank B, the outline of the fingers 82 'being best shown in FGURE l. In addition, each of the bottom flap folding members 43' and 5i is provided with a pair of projections S3 which are disposed in alignment with the intersections between adjacent bottles B in the rows of bottles. The function of the projections S3 -will be described in further detail hereinafter.
Although it is intended that the completed package engaged with the stop 37 provide the means for aligning the next set of bottles and the carrier blank with the carrier folding and locking means, the supports 46 and 4'7 disposed remote from the endless conveyors 23 are provided with suitable stop members S4 for engaging the forward edges of an advancing carton blank B, as is shown in FGURE ll, for the purpose of effecting the alignment of the carton blank with the bottom flap engaging members eti and 5l.
lt is to be understood that the packaging machine 15 is to be manually operated. To this end, it may be either operated by hand or by foot. With reference to FIGURE 9, it will be seen that there is illustrated a foot treadle S5 which is hingedly mounted, as at S6, to a suitable support 37 which may be mounted on the floor of the area where the packaging machine .15 is mounted. The foot treadle S5 will carry an elongated upstanding link 33 which has the upper end thereof pivotally connected to an arm S9 by a pivot pin The arm 39 will, in turn, be secured to one end of the shaft 57 for effecting the oscillation thereof.
lt is also to be noted that the arm S9 is provided with a pin 91; intermediate the ends thereof, the pin 9i projecting in the general direction of the adjacent end of the shaft 57. When a hand lever is to be used in lieu of the foot treadle 85, a hand lever 92 is pivotally mounted on the end of the shaft :'57 in partial overlying relation to the pin 91.. Since the hand lever 92 rests upon the pin 9i, downward movement of the hand lever 92 in a clockwise direction, as is shown in FIGURE 12, will result in the necessary pivoting of the shaft 57 to effect the operation of the means for forming and interlocking the carton blank in the formation of the iinal carton.
In order. to fully understand the operation of the packaging machine 15, it is first desirable to understand the general details of the construction of the carton blank 25 although these details may vary slightlyfrom carton blank to carton blank. The carton blank 25, as is shown in FfGURE 7, includes a top wall panel 33 having suitable openings'gl for receiving the necks of the bottles B. The carton blank 25 also includes side wall panels 95 depending from opposite sides of the top wall panel 93. The side wall panels 95 terminate at their lower ends in bottom flaps or panels 95, 97.
Reference is now made to FIGURE 13 where it is shown that the bottom flap 97 is provided with triangular openings 98 therein, the triangular openings 98 being closed by triangular members E9 hingedly connected to the bottom'ap 97 along the line 16d. On the other hand,
the bottom flap 96 isrprovided with lockingtabs MB1 along the free edge thereof. T he locking tabs lill are configu- Vrated to be pushed through the triangular -openings 9S and to interlock with the bottom ap 97 so as to lock the bottom flaps 9d and 97 together. It is to be noted that the triangular openings 9S are disposed intermediate the bottles B Within the finished carton, as is generally shown in FIGURE 8. Y
Attention is also directed to the fact that the side panels 95 are provided with suitable slits 102 and 1&3 adjacent the bottom flaps 96 and $7 so that when the carrier blank 25 is properly lapplied to the bottles E, as is shown in FIGURE 8, the outer lower portions of the bottles B will extend generally outwardly through the side panels 95.
Operation In accordance with the invention, the bottles B to be packaged are continuously supplied by the endless conveyor chains 23. When six bottles have been accumulated at station A, a carrier blank 25 is positioned over the siX bottles B in the manner generally shown in FG- URB 6. Then, 4the bottles yand the associated carrier Z5 are slid along the support strips 24 with the side panels 9S of the carrier blank 25 being engaged by the blank folding blades Sti, as is shown in yFIGURE 7. When the carrier blank 25 either engages the previously formed package P or the stops 54, the shaft 57 is rotated either by means of the foot treadletl or the hand lever 92. This rotation of the shaft 57 results in the bottom flap engaging or forming members 48 and 51 engaging the bottom flaps 97 and 96, respectively, and folding the same up underneath the -bottles B disposed on the support strips 24s'. Since the flange Sti projects inwardly with respect to the `flange 52, it will be yapparent that the flap 97 will be folded upwardly ahead of the flap 96. As the bottom blank folding members di) continue to move inwardly, the projections 83 will engage the lower portions of the side panels 95 and move the same inwardly in between the .adjacent bottles in the rows, as is shown in FIGURE 8, to `tightly wrap the carrier blank 25 around the bottles B. When the inward movement of the bottom flap engaging members 48 and 5l is discontinued, the locking tabs Alill are aligned with the openings 98. Further rotation of the shaft S7 results in the upward movement of the fingers '72 through the openings 98 forcing the tabs 101 through the openings 9d and urging the members 995 upwardly, as is shown in FIG- URE 8. The bottom flaps 96 and 97 are now interlocked 'and the package Pis completed. The newly formed package P is then moved to the left, as viewed in FIGURES 1 and 2, forcing the previously formed package down the ramp 36 and onto the take-away means 32. The operator is now ready to form another package.
From `the foregoing, it will be seen that the machine l5 is of such a nature whereby one operator may quickly and securely apply a bottle carrier ofthe wrap-around type to a plurality of bottles, for example, the six bottles shown, as desired. The mechanical features of the packaging machine 1S are extremely simple and require no adjustment once set nor are they subject to wear in an undesired manner.
From the foregoing, it will be seen that novel and advantageous provision has been made for carrying out Vthe desired end. However, attention is directed to the fact that variations may be made inthe example apparatus disclosed herein without departing from the spirit and scope of the invention, as defined in the appended claims.
