10 Claims.

This invention relates to machines for enveloping cigars, particularly to a machine for enveloping cigars in transparent cellulosic materials, such as Cellophane and the like.

The main object of the present invention is to provide an organized machine particularly designed for the enveloping of cigars in such material. While machines have already been developed for wrapping Cellophane about cigars,such machines have been in the nature of attachments and improvements grafted on foiling or other wrapping machines. Because of the peculiar nature of Cellophane and similar transparent cellulosic materials which are of a resilient nature which resists folding and unfolding, unless special measures are taken to prevent same, it has been found necessary in order to increase the speed, to completely redesign existing machines, particularly with respect to performing the additional steps or operations necessary for the best results with Cellophane at separate stations so that one operation does not interfere with or delay another.

Another object is to provide for a machine of this type in which the operation of the cigar car-v rier or turret tends to tighten the envelop as the result of the forward movement of the enveloped cigars. A further object is to produce a machine which has the above advantages and which so delivers the cigar from the turret that, after passing through a number of operating stations, it delivers the enveloped cigar in the same relative position to preceding and following cigars as said cigar occupied in the box row from which it was withdrawn for enveloping. Another object is to obtain greater speed through division of labor between stations such that successive operations are performed simultaneously on a number of cigars. Still another object is to provide a machine in which it is not necessary to withdraw the folders or other mechanism acting on the envelop before the cigar can be discharged, thus speeding up the ejection of the cigars at the discharging station. Another object is to provide a machine which is capable of a particularly wide range of adjustment for enveloping cigars of different sizes and shapes. With these and other objects in View, the invention consists in certain constructions and combinations which will be hereinafter fully described and then set forth in the appended claims.

In carrying the invention into effect, there is provided means for feeding a web of enveloping material, means for cutting an envelop from said web, 4means for folding the envelop circumferentially about a cigar With the longitudinal edges in overlapping relation, means arranged to feed cigars to said folding means, means for heat sealing the overlapped edges of the envelop, means for successively tucking, creasing, and folding back the ends of said envelop, a delivery table arranged to receive the enveloped cigar, and

means for transferring the enveloped cigar from said folding means to said table. In the best constructions contemplated, said web feeding means includes intermittently operating web feeding rollers and said cutting means includes a cam actuated knife operating to cut an envelop from said Web while the feeding rollers are inoperative. In the best constructions contemplated, also, said folding means includes an intermittently rotating turret provided with a plurality of pockets, a charging device comprising an oscillating pusher and a transfer arm cooperating with said pusher to assemble an envelop and a cigar in one of said pockets with the envelop folded about three sides of the cigar, and folding plates for folding the vedges of the envelop over the fourth side of the cigar in overlapping relation. In the preferred form of construction, said heat sealing device includes a cam operated sealer for uniting the overlapped edges of the envelop in said pocket, said means for tucking, creasing and folding back the ends of the envelop includes tuckers, heated creasing dies, and heated fingers, respectively, for performing these operations on the ends of the envelop in said pocket, and said transfer device includes a transfer arm receiving the enveloped cigar from said turret and discharging it on said table.

These various means and parts may be widely varied in construction within the scope of the claims, for the particular machine selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention, therefore, is not to be restricted to the specific construction shown and described.

Referring to Figs. 1, 2 and 3, the machine con-l sists of pedestals 20 carrying a bed plate 21 on which are mounted the end frames 22 and 23 and the bearing frames 24 and 25. The machine is driven through a belt 26 by a pulley 27 equipped with a friction clutch 28 which is operated through shift lever 29 fulcrumed on pivot 30 mounted on bracket 31. Shift lever 29 is operated by means of a cam 32 from hand lever 33 fulcrumed on pivot 34 supported by bracket 35. Pulley 27 is mounted on the main drive shaft 36 supported by end frame /23 and bearing frame 25, a concentric shaft 37 carrying crank handle 38 being slidably mounted in end frame 22 and bearing frame 2 4 to engage the drive shaft, for turning the machine by hand for purposes of adjustment.

The main drive shaft 36 is also equipped with a safety clutch 39 engaging with disk 40 of the .wardly by gear 41 which is loosely mounted on shaft 36 and which meshes with gear 42 on stud 43 supported by end frame 23. To gear 42 is pinned the gear 44 driving gear 45 mounted on cam shaft 46 supported by end frames 22 and 23 and bearing frames 24 and 25. Gear 45 meshes with gear 47 on the turret shaft 48, also supported by end frames 22 and 23 and bearing frames 24 and 25.

Shaft 48 carries the turret 49 which is provided with a sleeve 50 loosely mounted on said shaft. The turret 49 is provided with six radial arms 51 arranged at intervals of 60 degrees and having forked members 52 loosely mounted on pivots 53. The members 52 are normally pulled inwardly towards the turret arms on which they are supported through springs 54 connected to the cross bars in the arms of the members 52 and the adjacent turret arm and moved outthe folding members 55, fast on pivots 52, which are actuated by cranks 56 having rollers 57 held in contact with an oscillating cam 58 by springs 59 extending from pins 60 in arms 51 to pins 61 in crank arms 62 fixed to the pivots 53.I Cam 58 is oscillated by means of lever 63 having roller 64 in engagement with cam 65 mounted on shaft 46. The cam 58 is so designed that, at the proper moment as the turret rotates, the forked member 52, when actuated by folding member 55, brings the movable jaw 66 carried by it, towards or away from the stationary jaw 67 attached to arms 51, thus opening or closing the cigar pocket formed thereby at the end of each turret arm 51. The members 55 carry the folding plates 68 which are thus controlled by cam 58.

The turret arms 51 also carry folding members 69 equipped with folding plates 70, these members being supported by pivots 71 and controlled through cam levers 72 carrying rollers 73 by cam 74 oscillated by lever 63 and cam 65. The members 69 are equipped with tension springs 75 which secure contact of rollers 73 on cam.74.

The bottom Walls of the turret pockets are formed by plungers 76 yieldingly supported by springs 77 so as to occupy their radially outermost position when not held back by cigars in the pockets which, as soon as they are inserted by means hereinafter described, are clamped between

jaws

66 and 67.

Turret 49 is driven by means of a Geneva wheel 78 actuated from crank 79 and roller 80. Crank 79 mounted on shaft 81 is driven by gear 82 meshing with gear 83 mounted on cam shaft 46.

The cigars C after boxing, are placed layer by layer .from the box into the magazine 84 and are intermittenty fed layer by layer by fingers 85 carried by an endless chain 86 towards station I vof turret 49 by means shown in the copending application of H. H.,Wheeler, Ser. No. 268,434, filed April 9, 1928. Gear 87 on shaft 88 supported by bracket 89 operates the cigar carrying plate described in said application through means, not shown. Gear 87 is driven through intermediate gears 90 and 91 by gear 92 mounted on cam shaft 46; At the inner end of magazine 84, the cigars C are lifted one by one, by transfer arm 93 and transfer pusher 94, into the open turret pocket of station I. The pusher 94 is fastened to shaft 95 which receives oscillating motion from gear 96 meshing with gear 97 mounted on the hub of cam lever 98 having roller 99 engaging with cam 100 on shaft 46. Cam lever 98 and gear 97 are fulcrumed on pivot 101, fastened to bearing frame 24. The arm 93, however, is loosely mounted on the shaft and cooperates with the pusher to prevent rolling'of the cigar during the transfer operation so that the cigar may be delivered to the turret in the proper position to be wrapped and ejected therefrom in the position it will occupy in the cigar box.

Transfer arm 93 and pusher 94 take the cigar up to the turret pocket of station I, and While arm 93 is stopped in front of the said pocket through means hereinafter described, the pusher 94 inserts the cigar C with the envelop blank E, which has been cut to size and fed to the holder guides 102 by means hereinafter described, into the turret pocket, thereby folding the envelop about three sides of the cigar. The jaw 66 of the pocket then closes immediately by the action of cam 58, thereby holding the envelop firmly on the cigar.

The Cellophane web for the envelop is fed into the holders 102 from a reel 103 on a vertical core 104, by means of rollers 105 which receive intermittent motion through gears 106 operated by gear 107 on shaft 108, through a suitable gear train such as shown in my prior Patent No. 1,796,073, granted March 10, 1931. The gear 107 is connected to the shaft 108 by a ball clutch to drive it one direction only and is actuated from rack 109 hinged to lever 110 on shaft 111. Lever 110 carries the cam lever 112 having roller 113 engaging with the right-hand track of cam 114 and is thereby operated to reciprocate the rack 109. The envelop blank is cut to the required length by means of knife 115 attached to shaft 116 which is actuated through lever 117 and link 118 by lever 119 connected through shaft 120 to cam lever 121 carrying roller 122 engaging with cam 123 on turret shaft 48.

After the cigar C and the envelop have been assembled in the turret pocket and the latter has closed, the turret makes one-sixth of a revolution, this bringing the said pocket with the inserted cigar to station II where the inner lengthwise fold on the fourth side of the cigar is made by means of folding plate 68 on the leading edge of the envelop.

Moving to station III, the outer lengthwise fold is made by means of folding plate 70 on the trailing edge of the envelop, this final fold overlapping the inner fold and thefolding plate 68 which remains in the folding position until the enveloped cigar is ready to be sealed. By folding the edges of the envelop in this manner, the overlap is in trailing position when it-is discharged on the delivery table so that it does not tend to open lwhen it is forwarded thereon. Thereupon, the

tuckers 124, advancing from each side towards the ends of the cigar, Figs. 4, 5, .and 6, tuck the sides of the overhanging ends of the envelop as shown in Figs. 7 and 8, so that the same may readily be folded. The tuckers 124 are fastened to rods 125 mounted on bridges 126, Figs. 1 and 2, carrying studs 127 with rollers 128 which engage with cam tracks 129 of double-cams 130 on turret shaft 48. 'I'he bridges 126 are guided by horizontal rods 131 mounted in frames 22 and 24 and frames 23 and 25, respectively.

While the pushers 124 are tucking the ends of the envelop, the creaser dies 132 vand 133 start to move towards the cigar ends, and as soon as the fingers 124 have receded far enough, the upper creasers 132 engagewith the lo'wer creasers 133, Fig. 9, thereby creasing the tucked ends of the envelop E. At the same time, the creases so made are sealed by the action of the heating units 134, with which the creaser dies are equipped.

The creaser dies 132 and 133 are mounted on levers 135and 136, Fig. 3, pivoted on shaft 137 supported by bearing frames 24 and 25. Levers 135 and extensions 138 of levers 136, are connected through

toggles

139, 140 to rods 141 pivoted to levers 142 mounted on shaft 143 which is supported by bearing frames 24 and 25. Shaft 143 carrying crank arm 144, Figs. 1 and 2, is actuated through rod 145 by double-lever 146 having roller 147 in engagement with cam 148. In order to obtain an equal movement on both creaser levers 135 and 136, the pivots 149 connecting

links

139 and 140 with rods 141 are guided by slotted plates 150 mounted on bearing frames 24 and 25. By this construction, it is obvious that the creaser dies will have a positive action with much greater pressure than the constructions employed in prior machines of this type.

Coming to station IV, folding plate 68 moves out of the-way to allow sealer 151 to seal the lengthwise fold of the envelop. Sealer 151 which carries a heating unit L52 and is pivoted on rod 153, is operated by lever 154 from a cam, not shown.

The creased and sealed ends of the cigar envelop are projecting axially when arriving at station IV, and in order to' insure a neat appearance of the nished cigar package, these ends are folded back against the side of the envelop and sealed thereon. This is done by fingers 155 equipped with heating units 156. Fingers 155 are supported by adjustable pivots 157 fastened to brackets 158 of bearing frames 24 and 25 and are actuated by rods 159 fastened to guide bridges 160 carrying studs 161 provided with rollers 162 engaging in cam tracks. 163 of cams 130. The bridges are guided by rods 164 supported in

frames

22 and 24, and 23 and 25.

Moving to station V, the folding plate 70 releases the enveloped cigar and jaw 66 opens thus permitting the plunger 76 to eject the enveloped cigar onto a transfer arm 165 on shaft 166 actuated from gear'segment 167 engaging with segment 168 having cam lever 169, the roller 170 of which engages with the left-hand track of cam 114. Cam lever 169 is loosely mounted on shaft 111. The enveloped cigar is then clamped in the transfer arm 165 by the ejector-arms 171 which are loosely mounted on shaft 166 and have the gear segments 172 meshing with gear segments 173 mounted on shaft 111-which is actuated by cam lever 174 having roller 175 engaging with the right-hand track of vcam 176 on shaft 46. Arms 171 are equipped with hinges 177 and tension springs 178 so that they may yield as hereinafter described.

By the division of the enveloping operation between ve stations, greater speed is attained, .the present machine having a capacity of 80 cigars per minute while the prior foiling machines have a capacity of only 50 cigars per minute.

The enveloped cigar is discharged onto a delivery table 179 when the transfer arm moves downwardly through a longitudinal slot in said table and is resiliently pressed against said table by the arms 171. The cigars delivered on the table are released from the arms 171 and advanced step by step to make room for more cigars by the ejecting fingers 180 fastened on rod 181 supported by brackets 182 and operated through link 183 from lever 184 mounted on shaft 185 actuated through lever 186 and link 187 from lever 188 fulcrumed on shaft 111 having cam lever 189 engaging by roller 190 with the left-hand track of cam 176 on shaft 46. 'I'his construction provides a simpler delivery in which the enveloped cigar is moved through an arc of 45 degrees instead of 90 degrees as in the prior foiling machines.

The cigars while being advanced on the table 179 are guided with a gentle pressure by the adjustable top plate 191 supported on studs 192 slidable in slotted-cam plates 193 attached to frames 24 and 25. Plate 191 is liftable by arms 194 having the handle 195 and being pivoted on shaft 196 having an arm 197 movable between two stops 198 against either one ofwhich it is held by a tension spring 199 attached to pin 200 in frame 24. By this means the top plate may be readily swung out of the way without detaching any parts.

Cam 201 shown on shaft 46,. by means of roller 202 on cam lever 203, actuates a shaft 204 which, through levers 205 and 206, operates a gear segment 207. Lever 206 and segment 207 are pivoted on stud 208 mounted on frame 25. Cam 100 through cam lever 209 actuates a link 210. Segment207 and link 210 drive parts of the cigar feed not shown. To yieldingly hold the arm 93 in normal position with respect to the pusher 94, there is provided a spring 212 connecting the lugs 211 and 213, and a stop 214 on the pusher 94 engaging the pin 216 in the tail 215 of the arm 93. On its other end the arm 93 is provided with a stop 217 adapted to engagethe abutment 218 and stop said arm at a position in front of the envelop blank hol-d er, the spring 212 permitting the arm 93 to yield, with respect to the pusher 94 which then carries the cigar and envelop into the turret pockets.
