Application filed November 6, 1923. Serial No. 673,163.
This invention relates to apparatus as used for the gluing and sealing of wrapped arti cles, cardboard cartons, paper wrappers on cartons, et cetera, and has for its particular objects a simple, durable and reliable machine which thoroughly cements the entire surface of all the open flaps of a cartonor package, as against the localized application of cement heretofore used, andwhich will apply heat to the cemented joint to set the joint, and at the same time melt together the layers of a wax or other impregnated inner wrapping of the package or carton, whereby in a single operation the outer wrapping is sealed and the inner wrapping hermetically sealed.
I attain the objects outlined in the apparatus described in the following specification and shown in the accompanying drawings, and in which: I
Figure 1 is a side elevation of my com plete machine; Figure 2 a plan view thereof, Figure 3 an enlarged plan view of the receiving, cementing and folding elements of my machine Figure 4 a cross section of Figure 3 along the line 44l thereof;
Figure 5 a perspective view of the packbefore sealing and Figure 6 a cross section of the package.
Before entering a detailed description of the machine, the package to be sealed had better be described so as to give a quicker appreciation of the machine for sealing it.
The package as shown in Figures '5 and 1 represents a candy package, and consists of an inner cardboard container (1) for the candy, at waxed or paraiiined paper wrapping (2) folded by hand around the inner container, and an outer cardboard carton (3) into which the Waxed paper wrapped inner carton fits snugly and into which it is inserted by hand.
The outer carton is furnished by the manufacturers as a tubular article open at both ends, the longitudinal joint 1) being glued at the carton factory.
At each open end of the outer carton are four simple flaps, (5) and (6) denoting respectively, the upper and lower side flaps, and (7) and (8) respectively the two edge flaps.
My invention is concerned with the gluing down of the four flaps at each end of the outer carton as well as they heat sealing of the joints and overlapping ends of the paraflined inner wrapping.
In Figures 1 and 2 my machine is shown as having a supporting frame (9) adapted to rest upon the floor (10) and having the feeding end (11) of the apparatus at a convenient height for anoperator whose duty it is to insert the candy tilled double cartons, one at a time between thereceiving guide plates (12), each carton being inserted in front of one of the traveling slats (13) of an endless chain conveyor (1 1) carried over head and tail sprockets (15) and (16) rotatably mounted at opposite ends of the machine. The upper part of the frame supports long guides (17) slotted. for the chain and along which the cartons are dragged by the slats (13) which project above the slotted'guide. p I t On the frame is supported a motor (18) geared through means of a worm reduction (19) to a shaft (20), thence through bevel ggaging (21) to the head sprocket shaft 1.4.2 i r i The tail sprocket (16) is actuated by'the moving conveyor chain and has an extension shaft carrying pulleys (24)(21) at both ends belted to rotate the flap gluing wheels which revolve in suitable glue troughs (26), removable for cleaning.
Around the exposed portion of the tail sprocket (16) is a, guard (27) suitably braced to the frame as shown so that an opcrative can safely rest against it in feeding the machine, without danger of being injured by the sprocket or chain.
The cartons are entered between the guides (12) with theedge flaps folded down against the waxed paper wrapped inner carton and with the side flaps extended over the guides (12) as indicated in the enlarged view (Figure 3), and are caught each by a slat of the conveyor and after being sealed are carried toward the discharge chute (28) positioned overthe head sprocket (15).
The sealing of the flaps is effected through the combination of gluing wheels (25) and folding fingers or ears (29) and (30) as follows: V
The gluing wheels are wide face wheels with a bevel edge and are each inountedvto. rotate at an angle of forty-five degrees as best shown in Figure 4, with the lower part of the wheel revolving in a bath of liquid glue or other cement (31) which may be heated or not as desired, whereby the wheel edge and both sides are covered with the glue which is carried up as the wheel revolves and delivered to the carton flaps.
The wheel face is made of a width corresponding to the vertical height of the carton between the guide flaps so that it will coat the entire exposed surface of both edge flaps which have previously been folded against the inner package as explained. This gluing of the entire end of the carton is a particular feature of my invention in making a better seal and permitting the use of a cheaper adhesive owing to the additional gluing of the outer flaps, as the outer and lower sides of the wheel at the same time coat the respective inner surfaces of the upper and lower side flaps (7) and (8). The wheels are preferably grooved on the gluing surfaces indicated at (39) to increase the quantity of glue carried on them.
The machine is made to suit the length of the carton so that the wheels bear against the folded end flaps, and the side flaps are held lightly in contact with the sides of the wheel by sheet metal finger extensions (32) and (33).
From the receiving guides (12) extend suitable guiding plates (34-) and (35) toward the gluing wheels to insure that the flaps pass over the proper sides of the wheels.
After passing the gluing wheels the cars (29) strike the upper flap and through the action of their curved surfaces fold up the flap as the carton moves along, and after which a second set of similar ears repeat the operation on the lower flaps.
Upon the glued flaps all being folded against the carton as described the carton enters between two side walls (36) which hold the glued flaps tightly against the ends of thc carton while they are passed through a heating chamber (37) which entirely surrounds the conveyor and may be heated by any convenient means. but I prefer to heat it electrically; and the illustration is intended to portray an electrical oycn or heating box surrounding the conveyor and preferably of well known construction providing dill crcnt stages of heat controlled through switches (38) so that the most ell'cctivc heat can be easily produced.
The object of the elongated oven is to do two things: to dry, or partially dry the glued or cemented iiapsand at the same time to fuse the parafiine or wax coating of the inner wrapping so as to hermetically seal the inner package against the entrance of moisture.
The heat is therefore an intense one. but of short duration. so that the proper result is quickly achieved before the licat pcnctratee through the inner carton to injure the candy.
The duration of the heat depends of course on the speed of travel of the conveyor chain as well as on the length of the oven through which the cartons pass.
in describing my apparadus l have omitted any unnecessary reiercnce to the many constructive icaturcs common to such apparatus indicated in the drawings and well known in the art. as my invention is conlined to a device which will perform the successive steps to glue the outer package and stall the inner one by heat without especial limitation to detail except so tar as the peculiar form and mounting ol my gluing wheels is concerned: for this latter feature provides in a single wheel a means of transporting the glue or cement from a pan he ncath to three ditl'crcnt carton surfaces siniultancously. and covers the entire rlll'fllt'e'! of all the flaps instead ol :1 small strip only, as heretofore generally done.
The machine as described whilc primarily intended to seal candy packagcs. may laadaptcd to the scaling of any similar packages such as breakfast Foods and the like. and any modifications falling within the spirit oi my invention and adapting it to such use are intended to be covered in my appended claims.
I claim:
l. package scaling machine comprising an elongated guide. a traveling chain conveyor ihcrcalong adapted to convey the packages along the guide. a pair ot gluing wheels rotatably mounted at an angle alongside the guide adapted to revolve in liquid adhe ive at the lowcr cdgc and conta t th packages at their vertical Bilge-F. and rion elements for actuating the won and gluing wheels s multancou 'ly.
