This invention relates to lock joint cigar or other article enveloping machines designed to malte a lock joint fold'. during the envelo ing of cigars, sticks of candy, or similarly e ongated articles in a suitable envelop or foil or other wrapping material.
The superiority of the lock joint fold., wherein one edge is folded over and behind and under the other edge, over the usual lap fold in which one edge of the wrapping material is merely laid on top of the other edge, is obvious since the former fold will keep air out and moisture in, and does not easily become undone. rlhis fold is particularly advantageous for articles tapered towards the end, such as cigars, since this shape tends to cause the lap joint to gap open in defeating the purpose of the wrapping and making same less attractive in appearance.
In order that envelops' so folded may not add appreciably to the-cost of the enveloped character requiring relatively this purpose it is important that a machine for be provided which will be uite rapid in operation, and which will per orm the lock folding during the other enveloping operations. It is the main object of this invention to produce' such a device. Still another object is to produce a device of this few folding stations, simple in construction and requiring little change over prior lap fold enveloping machines.
With these and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations which will be hereinafter fully described and then more particularly pointed out in the appended claims.
lin the accompan ing drawings which form a part of this specification and in which like characters of reference indicate the same or cigar,
' l like parts:
Fig. 9 is a front elevation ofthe detail shown in Fig. 8;
Fig. 10 is a detail side elevation of certain folding mechanism shown in Fig. l; and
Fig. 11 is a rear elevation of the structure shown in Fi 10.
ln carrying the invention into e'ect there is provided means for forwarding cigars or other articles and envelops therefor having outstanding edges, means for pinching together the outstanding edges vo the envelop over. the cigar, mechanism for successively folding the leading edges over and tucking them behind trailing edges, and a device for laying the folded and tucked edges dat on the cigar to thereby produce alock joint between the .edges of the envelop. In the' -in construction within the scope of the claims,
for the particular structure selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention, therefore, is not to be restricted and means for l to the precise details ofthe structure shown and described.
Referring to Fig. 1 of the drawings theA cigars or other articles to be envelop are fed by any suitable means, such as a swinging transfer arm 21 and cooperating curved gui e 22, into the pockets ofturret arms 23. This turret and transfer mechanism is similar to that shown in acopending application for a cigar envelo ing machine by Henry H. Wheeler, S. .203,082,led Jul 2,1927. In the aforesaid machine, lap fol ing and end folding mechanisms for folding the envelop about the cigars in the turret are disposed about its periphery. To adapt this enveloping` machine to lock folding, the la folding mechanism is omitted and theloc folding mechanism, as hereinafter described, is substituted in lieu thereof, retaining the en folding mechanism.- Accordingly, konly so much of this enveloping machine structure is illustrated and described as is necessary to- "several enveloping and folding operations take place which stations' for convenience have been designated in the drawin and description by Roman numerals I to at station I of which the cigar is transferred to the turret and at station V of which the cigar is ejected therefrom. The turret 23, which is similar to that used imlap foldl enveloping machines, is given intermittent and clockwise rotation by suitable means such as the Geneva gear 24 mounted on sleeve 25 surrounding a stationary horizontal turret shaft 26.
fifi
i mndielg Each of the fixed arms 23 of the turret carry a. stationary jaw 27, and a -movable forked lever 29 pivoted to the arm 23 at 28, which lever carries a relatively movable jaw 30. Each of the'levers 29 is provided with two arms 31 and 32 extending rearwardl from the pivot point, one on each side of t e arm 23. Rollers 33 on the arms 31 bearon the circumference of al cam 34 on the stationary shaft 26, arms 31 being thus held byv springs The ci r C is pushedby the transfer arm 21 into t e envelop F, which in the form selected for illustration is of foil, thereby partl enwrapping the cigar within the envelop.
e arm t ereafter pushes the cigarand envelopl against a plunger 36 in a pocketv formed by t e ljaws 27 and 30 against the outward rassure of ringk 37 so that, as shown in ig.` 1 the cigar and envelop therefor are supported with their ed es outstanding. The relative ition :of tte cigar and the envelop material fed by the rollers 38 is made such that the'portion of the envelop above the cigar is somewhat longer than that below the -cigar to provide the extra material at the leadin edge of the envelo for making the lock fo d. As this occurs the wrapping material forming the envelopY F, which is interjmittently fed in timed relation to the movement of the transfer arm and the turret by feeding rollers 38,is cutoff by the usual knife bar 39 andledge'r block 40, the knife bar being oscillated 1n proper timed relation to the feeding movement o the envelop material.
In the preferred form of the device, the outedges of the .envelop are initially plnch .together (station II, Fig. 1) by the mtergeared pinchers 41 and 42, shown more in detail in Figs. 8 and 9. These pinchers bod are mounted just beyond the periphery'of the turret and each has an envelop engaging surface extending the full width of the envelop, the surface of the .pinchar 42 being broader-than that of the pincher 41 to corre- J spond to the greater width of the leading outstanding edge of the envelop. j These pinchers 41 and 42 are secured on shafts 43 and 44 respectively, suitabl supported vfrom the main frame of the en've oping machine, and these shafts carry gears 45 in mesh with each other whereby' the pinchers are intergeared. The shaft 44 carriers a lever 46 to which is connectedl by a pin 47, a rod 48 operated by suitable means not shown, such as a cam on one of the operating shafts of the enveloping machinefor reciprocating said rod as indicated by the arrow inlig. 1.
` Mechanism is provided for holding the outstanding edges of the envelop together, at station dll. These edge holding means, shown more in detail in Fig. 4, have envelop engaging surfaces similar to those of pinchers 41 and 42, but are independently actuated as follows: yllhe holders 49 and 50 are each mounted onthe shaft 51, the holder 49, being loose thereon, and `the holder 50 secure thereto. The edge holder 49 has an arm 52 to which is connected vby a pin 53 an operating rod 54, which is suitably reciprocated by means not shown trom a shaft of the enveloping vmachine proper. rlllhe shaft 51 mounts an arm 55 to `which is connected at 56 a rod 57, also suitably reciprocated by a cam not shown on a shaft of the enveloping machine. While it is preferred to provide means for initially pinching together the edges of the envelop at stationlll', it is apparent that in some instances this hrst pinching operation could well be dispensed with and such omission is contemplated, the edge holding means 49 serving for this purpose. i
To fold the leading edge over and tuck it behind the trailing edge, holder 50 is provided with a folding plunger 58, and the arm 55 on the shaft 51 is provided with a tucking plunger 59. Each of these plungers is slidable in slots in saidedge holder and arm. The 4folding plunger 58 1s positioned with its forward .trailing edge thereof. The tucliing plunger 59 (Fig. 4) moves in a direction at right ani gles to the directionvof movementof the foldmg plunger, being positioned with its Working surface in alignment with the edge holdin'surface ofthe element 49.
he plunger 58 is actuated by the cam 61 mounted on a shaft 62, and the plunger 59 is controlled by the cam 63 on shaft 64, both shafts being supported by a frame of the enveloping machine to which the device emying the invention is attached, and are connected with the drive shaft of the latter. At either side of the working face Yof theplunger 58 arev mounted 65 to which are .13
vsecured springs 66 hooked to` pins 67, which pull the slide outward into engagement with the operating surface of the cam 61. Similarly springs 69 secured to pins 68'in a slide 60 of the plunger frame hold the rear end lslide 59 in engagement with the cam 63, as shown in Fig. l0.
The 'folded' and tucked edges are then laid fiat by a stationary surface extending between station HI and station V provided by the guide plate 71 and curved concentrically with the turret and mounted close to its periphery.
This guide plate holds the foil wrapper in.
lace while its ends are folded by the end folding mechanism of the above mentioned enveloping machine. f f Y The operation of the devices above described is as follows: At station ll (Fig. 2) a cigar C pushes the envelop F against the plunger 36, while at the same time the envelop is cut to length by knife 39. Further movement of the transfer plunger 21 pushes the ci ar into the turret pocket between jaws 27 an 30 and folds'the envelop around three sides of the cigar. its the turret moves from station l to station Il, the depressed portion of the cam 34 permits the jaw 30 to close on and its envelop for folding. t station ll,
the outstanding edges of the envelop are pinched together by the pinchers 41 and 42,
as shown in Fig. 3, which thereafter open as shown in dotted lines to pei-untl movement of the turret 'arm to station IH. A t this station the outstanding edges of the envelop are a ain inched together as shown in Fig. 4, an whi e so pinched together the plunger 58 folds the wider edge over the shorter trail.- ing edge, as shown in Fi 5, the top edge of the pinching face of the e ement 49 serving as a cooperating folding surface. The plunger 58 is-then withdrawn, the pincher element 49 is opened by downward movement of the rod 54, and t e plunger'59 moves downwardly as shown in Fi 6, thereby tucking the overhang of the fol ed leading ed e down behind the narrower trailing ed e. heplunger 59 is thereafter moved up gy the operation of 59 the sprin 69 and cam 63. Downward movement of t e rod 57 and resulting movement of the pincher' element 50 ermite movement of the turret alon the sur ace of the concentric guide 7l whic laysfthe folded and tucked edges of the envelop hat, holdin the same in this position durin Aend folding. at sta tion IV, asfshown in ig. l7. At station V the jaw 30 is opened by raised portion 34.' of cam 34 actingon the lever 31, therebyejecting M" the complet y enveloped-cigar.
