. a ENGLAND MACHINE FOR SEALING CONTAINERS Application filed July 23, 1928, Serial No. 294,845fa1it1 in Great Britain August 10, 1927.

This invention is for improvements in or relating to machlnes wherein bands, stamps or the like are automatically wrapped around or partly'around packets, for exam- ;ple packets of cigarettes, and has for its 0 object the provision of a machine wherein bands or stamps may be applied to the packets at a greater speed and more efficiently than has been the practice hitherto.

The present invention consists of a machine for applying bands, stamps or the like which comprises 'means (for example, an oscillating sucker) for removing a band or the like from a pile; a gum roller for receiving said band or the like fromthe suckers and, applying adhesive to one side thereof, means (for example a suction roller) arranged to receive the band or the like from the said gumming roller and present the gummed surface thereof to the surface of a packet movable beneath the said suction roller, and means arranged to fold the said band around or partly around the said packet. V

.The invention ismore particularly de scribed in the accompanying .drawings,'in which V p Fig. 1 is a side elevation, partly in section of a machine adapted to apply labels to the broad side of a packet. p Y

Fig. 7 is a similar view to Fig. 2showing the machine adjusted forapplying stamps to the-narrow face of the packet;

. Fig. '8 is a front elevation to a larger scale of the suction apparatus shown in Fig. 1 and the associated parts; In this Fig. 9 is a detail of Fig. 8, and

view the. frame of the machine has been Figs. 10 and 11 show a device for folding the ends of the stamp around the bottom side of the packet.

I Referring to Figsfl, 2 and 3, the packets 1 are stacked in a vertical magazine 2 mounted on the bed 3. A continuous conveyor is arranged to carry a plurality of pusher pieces 5 and convey the same 1n the direction, f

of the arrow A beneath ,the magazine 2.

apply a band to one broad side of the packet.

when the said arm is'not raised by a packet the oscillating sucker hereinafter described is rendered inoperative. .The operation of the arm 2 will be described later withrefer- 1 ence to Fig. 8 of the drawings. The device for applying the band com- I prises a-stacker 6 in which a'pile of bands,

for example revenue stamps 7 are located as shown in Figs. 1 and 8, of the drawings. Mounted atthe lower end'of the'said stacker is an oscillating sucker 8 which is adapted to .move periodically intoengagement with the lowermost band 'of the pile. The sucker 8 is connected to a rotary pump 34cv of ordinary construction. The pump is driven by .a chain 35 from the main shaft 36 of the mac hine, and thersuction pipe 37 is connected to the sucker 8 as shown, and to the suct-ionwheel 19hereinafter described. The

-Each pusher piece 5 is arranged to remove a .packet' from the magazine and'carry the same beneath a ClGV1C6 whlch is adapted to suction tube 37 is connected to the sucker 8 r structed and operated in the following manner: V The valve-comprises a body 40 provided with vents 40a and having a sliding piston 41 mounted therein and connected by a rod 12 to a lever 48 which carries the detector arm 2 at the front of the machine. The valve is placed in the suction tube as shown and has an orifice 44 through which air can pass into the pump when the piston 41 is lowered. The lever 43 is pivoted to the frame at 45 and has a cam roller 16 which engages with a cam 47 which is driven by the main drive of the machine and timed to synchronize with the movement of the conveyor. When a packet reaches the position immediately beneath the detector 2, the roller i6 is about to drop down the depress'ion in the cam 47. If a packet is in positionbeneath the detector the lever 43 cannot drop and the suction in the pipe 37 causes a stamp to be fed, which stamp will eventually be applied to the packet at present beneath the detector. If, however, there is no packet beneath the detector the lever 43 will turn on thepivot 4-5 and pull down the piston 41, thus breaking the vacuum and preventing thGzfGQCl of the stamp. Due

to the fact thatthe bands are supported at their leading corners upona ledge 9, the initial movement of the sucker is to bow the leading edge of the first band downwardly whereupon a support 10 is automatically moved between the bowed edge of the band and the remaining bands in the pile as shown in Fig. 18, so as to support thesame against any further movement of the displaced band. The support '10 is wedge shaped and is provided at the thickest portion of the wedge with a roller ,11 as shown in Figs. 8 and 9 which, as the support passes between the separated'band and'the remaining bands of the pile, 'forcesthe separated band into engagement with a continuously rotating roller 12 and the band is fed down .a narrow slot between fixed guides 13 and 14. The sucker 8 and the wedge 10 are operated by the link work shown on Fig. 8.

A cam 61 rocks a shaft 62 through a cam roller 63. A bell crank'lever is also fixed to the shafty62 and the short arm 63 of this lever is connected by a link 64 to another link 65 carryingthe sucker 8.

The other end oflink 65 is pivoted to the frame at 66 and as the cam 61 rotates, the sucker swings up and down about'thiscentre. The long arm-67 of the bell crank lever carries the wedge 10 and roller 11 at its lower end and consequently these parts movein time with the sucker 8. The band then passes over a roller 15 which is supplied with gum from a gum wheel 16 rotating in a gumbath 17. A scraper 18 is fitted to the gum wheel 16 in the usual manner.

The band is carried forward by the adhesion of the gum on the wheel 15 through one half of a revolution, whereupon a rotating suction wheel 19- strips the band, by

means of suction, from the wheel 15 and ,the next oncoming packet.

greater than that at which the conveyor is moving and deliver the same on to a platform 21 beneath a vertical stacker 22. The platform is reciprocated vertically by means of a lever 23 operated by a cam 24. The sides of the vertical stacker are formed by brushes 25 and as the packet is moved vertically upwards the projecting ends ofthe band are brushed downwards on to the ends of the packet. 'VVhen the packets reach the top of the stacker the bands arefirmly secured to thespacket and the packets may be removed by' hand or ,by a reciprocating plunger or the'like.

If necessary, the band may be arranged to extend below the lowermost faceofthe packet as the same 'movedgthrough the vertical stacker andjfolders may be provided in the vertical stacker so as to fold the extensions of the band around the fourth side of the 'packet'so that theiband completely envelops the packet or the extension may be folded upon the underside of the packetby A suitable device for this purpose is shown in Figs. 10 and 11 which show sections of the vertical stacker 22.

Referring to Fig. 10, it will be seen ,that two spring fingers 48 are mounted at the sides of the stacker, and when the platform '21 rises up with the packet the spring fingers are pushed outwardly, and when the platform 21 descends, the fingers 18 snap inwardly as shown in Fig. 11 and bend the remaining folds of the stamp around the bottom of the packet.

In order to prevent wastage of bands particularly in the case of revenue stamps,

there is mounted adjacentto the gum wheel 6 contact with the gumwvheel will be carried around by adhesion, but due to the natural resiliency ofthat band which visnot in contact with the gum on the wheel, the same will move inia path tangential'to the gum wheel and be locateduponthe chute 26 hereinbefore referred to.

7 In some cases it is desired to place the stamp on the narrow edges of the packet method of driving the machine.

as shown in Fig. 4 and in order to do this it is necessary to feed the packet to the bed packets one at a time from the bottom of the magazine 27 in the manner indicated in Fig; 5. The packets are then conveyed on the rim of the wheel 28 and fall down into the guides 30 of the labelling machine. A fabric band 31 is fitted which keeps the packets under proper control. A cam 32 is fixed to the casing in which the wheel. 28 is mounted and cam rollers 33 on each of the Y pawls 29 run on this cam which is shaped to give the pawls the necessary movements for feeding the packets and passing clear of the guides. The wheel 28 is driven from the main drive of the machine through the conveyor spindle 49 (Fig.7 and a vertical shaft 50 which has bevel gears mounted at its ends. The upper gear gears with another gear 51 mounted on a small horizontal shaft, and the other end of this shaft has a spur 52 mounted thereon which meshes with another spur gear 53 fixed to the spindle 54: of the wheel 28.

F ig; 7 also shows diagrammatically the A pulley 55 driven by a belt is fixed to the main shaft 36 carried in the bearings 56 and drives the The stamp feeding mechanism is driven by the main shaft by spiral gears 58, the various units of the stamp feed beingdriven by ordinary spur gears mounted in the casing 59. a

The tucking wheels 20 are also driven by bevel gears 60 which drive another cross shaft carrying bevel gears (not shown) which drive other bevelson the spindles of the wheels 20. V V

The forward conveyor shaft shown in Fig. 1 is driven by a conveyor chain itself which is in turn driven by the shaft 49 as previously described, 4

It will be understood that the guides, the stacker and the stamp applying-mechanism will require adjustment from the position shown in Figs. 1 and 2 when the packets are fed edgewise.
