WRAPPING MACHINE.

Application filed June 2,

T 0 all whom it may concern:

' Be it known that I, FRANK YV. Luv, a citizen of the United States, residing at Astoria, Long Island, in the county of Queens and State of New York, have invented certain new and useful Iinprovements in Vrapping Machines, of which the following is a specification. This invention rel-ates to machinery for wrapping packages of cigarettes and the like.

The principal objects of the invention are to provide a machine of this character, which will operate rapidly and eiiiciently to automatically apply wrappers, labels or the like, and which will be of durable and relatively simple construction.

In the form of the invention which I have herein disclosed, the wrappers are fed from a wrapper magazine into position in front of a pusher which doubles the wrapper over the articles and forces the same into folding boxes provided in a traveling carrier. These boxes are constructed with corner folders which turn in the corners at the forward edge of the wrapper. The carrier is then advanced to carry the inserted wrappers into position in line with a second set of corner folders. In the course of travel of the wrappers from the first station to this second station, the ends of the wrapper are brought together and at the second station, another pusher ejects the wrappers past this second set of corner folders, so as to turn in the rear corners of the pack age. In this ejecting movement, the wrappers are carried past edge-folding devices which close the edges of the wrapper together, after which the closed wrappers are ejected by a packer onto a suitable carrying off conveyor.

In the accompanying: drawings I have illustrated the invention embodied in this one form, but I would have it understood that various changes and modifications may be made without departure from the true spirit and scope of the invention as herein defined and claimed.

In the drawingsreferred to:

Figure 5 is a broken side elevation of the wrapper magazine.

Figure 6 is a sectional view of the same,

on substantially the plane of line 6-6' of a combination of related devices, by- Whicl' the cigarettes are bundled and each bundle 1S wrapped in a single cover.

The articles to be packed or labeled, in

this case the cigarettes,-a'resupported a hopper or magazine 15, which may be or the type consisting of a box-like structure which is agitated by means of acrank 16' and rocking lever 17, to cause the cigarettes to feed down evenly in the comparti-ne'nts between the partitions 18', from which'they are ejected by the multi-fingered plungers 19, to a chamber where the two rows of cigarettes thus ejected are combined by the co-operating slides 20' into a bundle, such as indicated at 21 in Figure 145. I r

The bundle thus formed, and while held in this shape within the guide channel provided therefor, is engaged by the plunger 2-2 and advanced against a previously positioned wrapper or label 23', servingias it is thus advanced to double the wrapper over the forward endof the same and to carry the doubled wrapper into a folding hon or pocket. I

These'foldingboxes are designated and consist of open ended compartments connect ed to form an endless chain supported on the

sprocket wheels

25 and 26.

The boxesare shown as rigidly constructed elements mounted on a. flexible support ing band or belt 27 and are each shown as secured to said band along a single line 28 (Figures 3 and 7 substantially transverse to the line of flexure of the band in passing over the sprockets or pulleys, so as not to interfere with the flexing of the belt. Interiitting lugs and sockets on the belt and supporting-sprockets maintain the parts in proper relation and also serve as driving means. In the illustration the seats or recesses are shown at 29, as formed in the sprockets and the lugs are indicated at 30 in. the form of cleats secured to the under face of the flexible band inline with the fastening of the folding boxes thereto. For.

the sake of simplicity, the same fastenings which secure-the boxes in place may be extended through to fasten the lugs at the under side of the belt, substantially as I have indicated at 31 in Figure 7 The carrier described is intermittently advanced with a step by step motion to carry the folding boxes to and past the different folding instrumentalities by means consisting in the illustration of Geneva gearing, involving a disc 32 carrying a pin 33 engaging at each revolution of the disc in a slot 34: in the carrier sarocket 2G and having an arcuate rim or flange 35 taking into the arcuate pockets 36 in the side of the sprocket at the end of each shifting movement; to hold the sprocket stationary for the balance of the revolution of the disc,

Thewrappers or labels 23 are automatically fed one by one from the magazine 37 by feeding-out devices consisting in the illustration of a pluralityof frictional belts 38 of rubber or the like (Figures 4:, 5 and 6) supported on pulleys 38 with their upper runs standing above or substantially in the plane of the bottom of the magazine, so as to engage the lowermost wrapper therein. The pulleys for these-friction belts are car ried by the shafts 39 and an intermittent feeding operation is obtained by intermittently rotating these shafts in a feeding-out direction.

. This intermittent feeding movement is imparted to the shafts 39 from a reciprocating rack 40'1nounted in guides tl on the side of the magazine and engaging with the gears 42 carried by the sleeves 13 loose on the shafts and which sleeves carry the discs 44', supporting spring-pressed pawls 45 in engagement with the ratchets 46 fast on the ends of theshafts. These pawls and ratchets are faced so as tooperate the conveyor shaftsonly in the feeding-out direction or toward'the right in Figure 5.

:The wrappers separated by the feedingout devices are advanced to the station. where they are acted on by the feed plunger 22 (igure 14) through a guide-Way, including the opposed sets of conveyor belts 4E7 l8 which may be constantly driven and which extend down far enough to drop the wrappers accurately in the stationary guide'channels 49. V p 7 In the illustration I have utilized this constant drive of the feed belts to effect the reciprocating movement of the feeding-out rack. The connections for this purpose, as best shown in Figure 5, comprise a crank disc 50 driven by gears 51 from the upper opposed sets of belts being connected by a' suitable chain of gearing, such as I have indicated at 57.

The wrappers are properly registered in front of the pockets in the conveyor by a suitable or gages, such as shown in Figure, 14, in the form of stop pins 58 ca r ried by the plates 59 adjustably secured by the thumb screws 60 at the lower ends of the guide channels 49. .The adjustability of these registering devices enables the adaptation of the machine to different sizes or styles of labels and the independent adjustment of the two stops is important in that it enables the wrapper to beftilted one way or the other until the proper efiect is ob tained.

The first wrapper applying operation consists in forcing the article or packet against the previously positioned wrapper and into one of the folding boxes in the carrier, so as to double the wrapper over the forward or leading edge of the article. This condition is illustrated in Figure 7, wherein the article feedingplunger 22 is shown as having forces the bundle of cigarettes far enough into the folding pocket to double the wrapper over the top and bottom of the bundle;

As the doubled wrappers are insertedin the folding boxes, the forward corners thereof are broken and turned in by corner folders 61 mounted in opposed relation in the folding boxes at the side furthest from the feeding-in plunger 22. 'These cor.- ner folders are shown in the form of blocks or lugs extending inward into the box from the opposite side wallsthereof and having opposed. substantially flat and parallelside naeaasi faces 62 to shape and confine the sides of the entering package and tapered or wedge shape forward ends63operat1ng as wedges to'form the preliminary break in the ad- Vance edge of the wrapper.

Spaces 64 are left in the folding boxes above and below the corner fold blocks for the laterally ex tending side wings '65 of the entering wrap The. folding boxes may be conveniently constructed as best shown in Figure 7 in the form of substantially U-shaped castings or members having the inwardly extending folding blocks 61 carried by the opposite sides thereof and having the tops closed by plates 66 which may be socured in place by screws or other suitable fastenings 67. This makes the construe-- 'tion of these boxes relatively inexpensive and at the same time enables the boxes to be readily opened up to gain complete access to the corner folders, in case, for 'instance, it is found that said folders are not operating properly.

After the wrappers with theco-ntained ar ticl'es are fully seatedin the folding boxes, and the forward corners of the wrapper have been thereby broken in and shaped, the carrier is advanced by the intermittent movement described, to carry the project- 111g upper rear edge 68' of the wrapper beneath a down turned folding flange 69 (Fig-- ure 7) which turns the edge downover the rear end of the article into the form of an end flap, as Shown in Figure 8'.

lower flap 70 up over the down turned flap 68', as shown in Figure 9, thereby completing the closing of the rear end of the wrapper. lVith the rear end thus closed, the package wrapper is then brought into registry witha slide which ejects it from the folding pocket.

The construction and operation of this ejecting slide will be best understood from Figures 1 and 10, wherein, the slide is indicated at 74: and is. shown. standing atthe opposite side of the conveyor from. the feed ing-in slide and in position to engage and eject the package from the foldingbox, which is then in registry therewith.

As the packages are ejected by this slide, they pass into. a channel indicated generally at 75 in F igure 1, and in which are arranged first, a set. ofrear edge corner folders 76 then a set of down turning flap folders-'7"? and finally, a set of lip turning flap folders 78 (Figures 19' and 12:)...

As the package passes beneath the upper flap folders 77 (Figure 10), the lower out standing flaps 65 pass under the glue or ad hesive applying rolls 79 and receive a strip of adhesive, as indicated, so that said flapsare in condition to seal the package when acted on bv the final folders 78 upon the next movement of the package.

The packages after being thus completely scaled, pass, out'the end of the guide pas sage 75 beneath a plunger 80 (Figures 1 and 2) which delivers the completed packages through a chute 81 onto the carryingoff conveyor 82. i

From the foregoing it will be seen that the carrier with the folding'boxesis intermittently advanced to bring the same into register with the several folding devices. At the first station, a wrapper is automati call'y' fed out of the magazine and positioned in front of the open endof a folding box.

the wrapper, so as to'fold the same across the leading end and over the top and: bottom of the bundle. In this feeding-in move ment, the forward corners of the wrappers are turned in and folded by the corner folders in the opposite sides of the box (Fig. 7).- As the carrier advances in its next movement, the upper rearward edge 68 of the wrapper is turned downward by the stationary flap folder 69.

In the next advancing movement of the carrier, the lower rearward edge'YO of the wrapper is carried beneath the pasting rollor 71 8) and on the succeeding advancing movement of the carrierthis lower pasted flap is turned up by the flap turner 73,

so as to close the rearward end of the packvanced to bring the package into register with the ejecting slide 74. This slide, in ejecting the wrapper with its contents, forces the rearward closed end of the wrapper past the corner folders 76 which turn in the rear corners of the package, as. shown.

in Figure 10. The stroke of the pusher 74 may be just suiiicient to. discharge the package-from the folding pocket, the advancing movement of the packages through the discharge channel 7 5 being accomplished by the engagement of one package against an-.

other. After passing .the rear set of corner folders 76, theupper' fiap's65 of the wrapper are turned down'by' the flap folders 77 over the turned in corners, the lower outstanding flaps receive a supply of adhesive and then in the further movement of the packages,

the finalv folders 78' turn up the lower adhesive flaps 65 and thus seal the package. The discharge. channelv 75 may be arranged to it the packages rather closely, so as to insure their being-properly sealed and it is for this reason that the packing plunger is provided, to positively e ect the finished packages from such channel.

it is, of course, important that the fold The various related instrumentalities de scribed are all mounted on a suitable base or framework and suitably connected so as to operate in properly timed relation. In therm'achine here-in disclosed, I have illustrated a suitable supporting frameworlrat 83 and have shown the parts as all driven from a main power shaft 8 on whichare mounted the fast and loose pulleys 8586 respectively. This main power shaft drives through spur gearing 8'7, a cross shaft 88 connected by bevel gearing 89 with a longitudinally extending shaft 90 and which latter shaft drives through bevel gearing 91', the cross shaft 92 which carries the disc'32 of the Geneva gearing for operating the carrier. This cross shaft 92 is shown as utilized also for driving the carrying-oif conveyor 82 through sprocket chain connections indicated at 93. v r

The feeding-in slide 19 is operated through a link connection 9&, from the rocking arm 95, which is mounted on rock shaft 96, said latter shaft being actuated through a rock arm 97 and connecting link 98 from a crank disc 99 on the end of shaft 90.

The ejecting pusher 74: is shown as operated through a connecting link 100 from rocker arm 101 on rock shaft 102' which is connected by gearing 103 with'the first rock shaft 96.

The upright shaft 53 which drives the magazine feed rollers is shown as driven by bevel gearing'104i (Fig. 3) from the .cross shaft 88.

The first set of gluing rollers is driven, in the illustration, through a. system of gear- 105 (Fig. 3) from a transverse shaft 106 connected by suitable bevel gearing with the upright'shaft 58. r

The second set of adhesive applying rollers areshown in Figure 1 as driven by gearing 107 from a longitudinally extending shaft 108 driven by bevel gearing 109 from the upright shaft 53. V r a The crank disc 16 for agitating the hopper is illustrated as carried by a shaft 110 connected by bevel gearing 111 with the longitudinal shaft 108.

The packing slides 20 which bundle the yersely acting right hand slide 20.

cigarettes into the form shown in 1d, are actuated in the illustration by a rocking lever 112'shown in Figure 2 as o aerated b g a cam 113 on the cross shaft 88, sa d cam lever being directly connected. at its upper endwith the left hand slide :20 in Figure 1 and serving through the rack and pinion gearing illustrated at 114 to operate the re- The dischar in lun er 80 is illustrated v 2:: P s in figure 2 as operated by a rock arm 115 011 rock shaft 96 connected by a link 116 with the lower end of the sliding rod 117 which supports the plunger.

In my invention the operations are en-" tirely automatic and in view of the results accomplished, it will be seen that the ma chine is of relatively simple construction. The parts are all durable and not likely to get out of order and may be driven at relatively high speed without impairing the work turned out by the machine.
