ATTORNEY HHHIIIHIIHHIIIHHJIl 111 H I I I atent 3,019,58 l Patented Feb. 6, 1 962 chine & Foundry Company, a corporation of New Jersey Filed June 20, 1958, Ser. No. 743,298 17 Claims. (Cl. 53-236) This invention relates to cigarette making machines, and more particularly to an apparatus and method for automatically collecting finished cigarettes or other rodshap'ed articles, in trays or other comparatively deep containers.

Heretofore, it has been the practice to accumulate the finished cigarettes on collecting belts which forward them to a collecting table. The cigarettes were then manually gathered and transferred to trays that were removed to cigarette packaging machines. This manual gathering, handling and placement of'cigarettes had a deleterious effect upon the quality and appearance of the cigarettes. Previous machines for mechanically loading cigarettes into trays required trays of special design which was objectionable.

One of the objects of this invention is to provide an improved mechanical device for placing cigarettes into standard trays.

A further object of this invention is to provide an automatic device for collecting cigarettes or other rod-shaped articles which will be of simple design and be reliable in operation.

A further object of this invention is to provide a machine which will convey cigarettes gently to avoid loss of tobacco from the ends thereof.

A further object of this invention is to provide a cigarette collector having a cigarette feeder which only delivers cigarettes into receiving trays while moving in one direction, thereby allowing full loaded trays to be indexed or replaced with another direction.

A further object of this invention is to provide for periodic delivery of cigarettes from the delivery end of the belts while continuously and without interruption receiving cigarettes on the receiving end of the tromboning belt.

A further object of the invention is to provide a device for aligning cigarettes or other rod-shaped articles on a conveyor.

A further object is to provide an apparatus for collecting tipped cigarettes in trays which allows for differences in diameter of mouthpiece and cigarette filler lengths.

A further object of this invention is to provide a method and device for the automatic indexing of cigarette trays.

A further object of this invention is to provide a cigarette tray loader which may be built into the confines of an existing cigarette makingmachine.

A further object of this invention is to provide an automatic cigarette collector having a distributor resembling a beak which will descend inside a tray to evenly dis charge cigarettes or other rod-shaped articles within the trays.

A still further object of this invention is to provide a cigarette collecting apparatus having a tromboning or empty trays when the feeder travels in.

telescopic type of motion to uniformly load cigarette trays.

A further object of this invention is to provide a timed tray feed for feeding empty trays to a point beneath the cigarette feeder, and for simultaneously removing filled tra s.

1: further object of this invention is to provide means to take-up and play out the tromboning belt so as to maintain a uniform tension therein.

Other objects and features of the invention will appear as the description of the particular physical embodiment selected to illustrate the invention progresses.

This invention is an improvement to the co-pending patent application of George Daniel Horgan, file Number 688,375, filed October 4, 1957.

In carrying our invention into effect it may be attached to any suitable cigarette making machine such as that described in co-pending US. patent application of George S. Dearsley, file Number SN 509,293, filed May 18, 1955, or as shown in FIGURE 1, it may be used in conjunction with a cigarette catcher machine of the type shown in US. Patent No. 2,124,397, wherein the severed cigarettes are discharged sidewise from the rod conveyor belt 2 by deflectors 4. The rod conveyor belt 2 is arranged to run at a linear speed somewhat in excess of the linear speed at which the endless tobacco rod is traveling before being cut into cigarette lengths. By this known technique the individual cigarettes are axially spaced from one another.

In the embodiment used to illustrate the invention, the cigarettes are ejected onto a collecting tape 6, traveling over suitably driven rollers 8 and 10, traveling in the direction indicated by the arrow 12. A sponge rubber roller 14 is mounted above roller 8 and spaced therefrom by a distance slightly less than the diameter of a cigarette, so that, as each cigarette passes in the space between those rollers 8 and 14, it is gently retarded andaxial movement is stopped without injury to the cigarette ends.

The collecting moving surface of tape 6 may receive any desired number of rows of cigarettes from the cigarette maker. In this particular invention we have shown the collecting tape 6 receiving two rows of cigarettes.'

While the cigarettes are deposited upon the receiving tape 6 in a position generally parallel with one another, their ends are not in proper alignment.

The aligning portion of our invention corrects this misalignment of ends, and arranges the cigarettes in proper axial and end alignment with one another and transverse to the direction of the tape.

It also permits a wider separation of the adjacent ends of the cigarettes on the catcher tape 6 than was effected by rod conveyor belt 2, thereby providing a positive method for transferring cigarettes onto belts 32.

A cigarette separator bar 18 is positioned by suitable means over the center of, and in close proximity with, the tape 6, at a point upstream of the roller A pair of diverging belts 20 and 22, and having their sides vertically arranged traveling in the direction of the arrows 24, over two pairs of vertical rollers 25 and 26, and 29 and 30 respectively shown in FIGURE 1, and supported by suitable means, are positioned at a point downstream from separator bar 18.

The belts 20 and 22 travel at a speed equal to the speed of the tape 6 with their lower edges being adjacent to the upper surface of the upper lap of the tape 6. Belts 20 and 22 are driven by belt 16 in any suitable manner such as by gearing or a friction drive.

The belt 16 travels at an elevation higher than pulleys 26 and 30. As the inside end of irregularly positioned cigarettes come into contact with the upstream surfaces of the belts 20 and 22, they are gently pushed endwise into alignment with each other as shown in FIG. 1.

The aligned cigarettes are then deposited, in an orderly and straight manner, on belts 32.

Referring to FIGS. 1 and 2, endless belts 32 travel over rollers 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56 and 58. The rollers 36 are rotatably mounted in horizontally reciprocal carriages 60.

Second carriages 62 are suitably supported on the carriages 60 and are vertically reciprocable. Second vertically reciprocable carriages 62 have rollers 38, 64 and 66 rotatably supported therein. Endless driven resilient surfaced belts 68 travel over rollers 64 and 66 and are so spaced with respect to the rollers 36 and 38 that the distance between the opposite vertical runs of belts 68 and 32 will be spaced from each other a distance equal to substantially the diameter of a cigarette. The cigarettes are transferred downwardly between the vertical parallel runs of belts 32 and 68 as shown in FIG. 2 and are deposited in horizontal rows in the receiving trays.

Sometimes when cigarettes are dropped a short distance they may have a tendency to bounce and fall askew. Cigarettes thus deposited would not be aligned nor parallel to one another and would create difficulties in the packaging operation. To prevent this problem from arising we have shown a modified version of the discharge end of: the belts 32 and 68.

When commencing the filling of one tray 70, the initial row of cigarettes must lay squarely across the plane, flat surface of the tray bottom. Cigarettes deposited from above, on such smooth surface, sometimes tend to roll out of the desired position.

Also in the movement of the tromboning belt system back and forth in the tray, the center line of the cigarette flow can come no nearer the ends of the tray than a dimension equal to the diameter of pulleys 38 and 66. This being the case there may be a void space left at the end of each layer of cigarettes in the tray unless other provision is made.

To provide for this the lower portion of the parallel, downwardly moving belts 32. and 68 are provided with means to feed the cigarettes in a sidewise manner so as to exert a degree of control in the flow of cigarettes and to deposit cigarettes into the void space under the rollers at the end of the feeding actuation.

A time delay relay system has been built into the electrical circuits controlling the magnetic clutches that drive the tromboning belts system back and forth across the tray. This delay will permit the corners of each path of the tromboning belt system to be filled when there is a deflecting mechanism to turn the flow of cigarettes into these void spaces.

When the tromboning belt system is in position as shown in FIG. 6, the flow of cigarettes is directed into the corner 72. The time delay is set to accommodate that many cigarettes. When the tromboning belt system is in position as shown in FIG. 7, the flap 74 is moved back as shown. The flap 74 is moved by an actuating bar 76 mounted on shaft 78. Shaft 78 has a rotary solenoid mounted on its end which rotates it in the direction required to contact bar 76 with the flap actuating bar 80 at point 77. When the flap 74 is moved back and up, the cigarettes are dumped into the corner 73, thereby, filling the space under the roller 38.

As the tromboning belts are returning toward position as shown in FIG. 6 with no cigarettes being dropped, the flap 74 is raised above the level of cigarettes laying in the tray. This prevents the misalignment of cigarettes already deposited in the tray. As the tromboning belt system approaches position as shown in FIG. 6, bar 80 comes into contact with the tray end at point 79, thereby, swinging flap 74 into position again to deliver cigarettes into the tray as shown by position of flap 74 in FIG. 6.

Flap is suspended as shown in FIG. 6 at a distance of two cigarette diameters from flap 74. This is to facilitate the desired reservoir of cigarettes for proper control of cigarette fio'w. Flap 75 is also suspended in its shown position to dampen the bounce of the cigarettes as they are deposited into the tray. These flaps 74 and 75 are made of thin metal and felt. The metal part is the top or hinge-half and the felt part being the lower half that should be flexible when coming into contact with cigarettes in the trays. Flop 74 has the metal to form the contour of the flap and the felt to dampen the bounce of the cigarettes when leaving the control of the vertical elements of the tromboning belt system. Flap 74 has also a contour to suit the angle of the bottom of the tray. When the cigarettes roll off of flap 74 they are falling with their axis positioned in a parallel plane with the bottom of the tray.

The belts 32 and 68 and the carriages 60 and 62 are operated in timed relationship with respect to each other so that when empty trays are positioned under the lower end of the belts 32 and 68 below rollers 38 and 66, the carriages 62 Will be lowered to bring the lower delivery end of belts 38 and 66 to a position close to the bottom of the empty collecting trays. As the belts 32 and 68 continue traveling in the direction indicated by the arrows 69 shown in FIG. 2, they will cause cigarettes to be deposited along the bottom of the trays 70 in horizontal tiers when the carriages 60 travel inwardly so as to deposit substantially horizontal layers of cigarettes across the respective trays.

When the carriages 60 have reached their innermost distance of travel, the carriages 62 are elevated a suitable distance from the cigarettes previously deposited, having finished their cigarette feeding actuation, and the carriages 60 commence traveling outwardly. The surface feed of belts 32 being driven by rollers 34, is equal to the reciprocating feed of carriages 60 so that when the carriages 60 travel outwardly, the cigarettes held between the opposed belts 32 and 68 do not move downwardly, hence no cigarettes are deposited in the tray during the outward travel of the carriages 60. However, when the carriages 66 commence traveling inwardly, cigarettes held between vertical runs of belts 32 and 68, will again'cornmence traveling downwardly and another tier of cigarettes will be horizontally deposited along the receiving trays being filled. With this technique, a periodic delivery of cigarettes may be obtained from the delivery end of belts 32'and 68 while a continuous and uninterrupted flow of cigarettes is being received from the making machine on the horizontal run of belt 32.

The belts 32 have the tromboning efiect described because of the vertical movable rollers 44, 48, 52 and 56, which take up the slack when the carriages 60 move inwardly and play out the belt 32 when the carriages 60 move outwardly. The movable rollers 44, 48, 52 and 56 impart the desired amount of tension to belts 32 and are interconnected by suitable means, so that they all move up and down together. The amount of tension exerted by the movable rollers may be controlled by the weight of the rollers or if desired, spring means may be employed to impart the amount of tension desired.

In FIGURES 3a and 4, the trays 70, 82 and 84 are shown supported on a suitable conveyor 86 and are intermittently indexed or advanced in the direction indicated by the arrow 88. In addition to this rapid indexing motion, a continuous slow creep motion is provided in the direction of arrow 88 to maintain the back of trays 70 in close proximity to the delivery end of belts 32 and 68 as the carriages 62 are retracted vertically out of the tilted trays 70. When the pair of trays 70 become full, vertical carriages 62 are elevated out of trays 70. Trays 70 are then indexed forward and empty trays 82 are indexed under carriages 62. In FIG. 5, it is shown how trays may be automatically indexed as will be described hereinafter.

The tray slide 86, having a width approximate to that of a cigarette tray, is positioned transverse to the direction of the movement of the tromboning belts 32, to support the trays on their way to a tray discharge station (not shown).

Tilted trays serve to better contain the cigarettes as the trays are being filled. The tilt facilitates the shifting of cigarettes lengthwise into the tray when disturbed by operational vibrations. It also permits sidewise indexing of a full open-side tray without the danger of the column of cigarettes spilling out through the open side during the shock of indexing. This tilt is also required because filter tip and cork tip cigarettes have a large di ameter end. This end builds up to about 5 degrees when the level of the cigarettes are nearing the top sections of the trays. While tilted trays afford a convenient means for controlling cigarettes in deep trays it must be understood that this invention is not limited by this consideration since it will function equally well with trays in a vertical position with other suitable control means to retain cigarettes in the trays. This may be -accomplished with flaps or vertically moving tray covers attached to the retraction mechanism.

It has been ascertained that an inclination of 8 degrees of the slide 86 produces the best results. However, it should be understood that an incline of greater or less than 8 degrees will not materially affect its operation.

Substantially vertical rotatable shafts 92 are positioned at all four end corners of the tray slide as as shown in FIGURE 3a.

While We have shown how sprockets and sprocket chains may operate, any other suitable belt and pulley system may be used. Sprocket wheels 94 are mounted adjacent to the ends of these shafts 92 and rotate therewith.

These shafts 92 are set substantially perpendicular to the slide 86 so that the axis of the sprockets 94, and those of the sprocket chains 96 traveling over those sprockets 94, will likewise be substantially perpendicular to the slide 86.

Endless sprocket chains 96 having cleats or lugs 1M- afiixed to their outer surfaces, describe a closed path of travel around the sprockets 94.

The lugs 104 on all the sprocket chains 96 have a spaced relationship to the effect that as an empty tray 82 is positioned transversely on the slide 86, near its base, a lug 104 from each of the chains 96 supports each corner of the rearward slide of the tray 84 during its ascent along the slide 86.

The shafts 92 are all in timed relationship with each other to ensure that the trays move at all times along the slide 86 in a position transverse to the slide 86..

One of the shafts 92 is power driven and transmits power and timing to all the other shafts in any suitable manner.

There are two distinct motions necessary to accomplish tray indexing. One is a creep motion for the slow constant movement of the sprocketed conveyor chains 96. This motion is needed due to the 8 degree tilt. The cigarettes are fed vertically into the trays and as carriages 62 are elevated the trays creep up slide 86 to stay under carriages 62.

The other is the indexing motion, serving to move two fully loaded trays 84 from the loading zone, and two empty trays 32 into loading position.

FIGURE 5 indicates schematically how these two motions may be obtained. All of the mechanism shown therein is located in the gear box 106 as indicated in FIG. 3a.

Mainshaft 168 is the prime mover of this system, driving both creep and index motions. A crank 11% serves to move ratchet arms 112 which turn ratchet 114. This in turn, through a suitable belt or sprocket chain 116, motivates the conveyor drive shaft 92 on which a tray conveyor sprocket 94 is mounted as shown in FIG. 3a.

Another method of obtaining this creep motion would be to connect the motion of mainshaft 108, through suitable gearing and speed reduction, directly to a conveyor shaft 92.

The sprocket or gear located at the conveyor drive shaft 92 would then be mounted on an overriding coupling to permit the indexing motion to function. This would provide constant creep for the tray conveyor chain 96. The ratchet type creep system gives intermittent motion and permits overriding of the indexing system movement.

As the creep motion moves a tray, the positioning notch 118 in the tray indexing ratchet 120 moves into position under the indexing ratchet pawl 122. This notch 11?: may be ahead of the pawl 122 at the time of indexing, but it should never be behind the pawl 122 at the instant of indexing motion.

The indexing system works as follows. Sprocket 124 is located on the main drive shaft 108 and is keyed thereto. The indexing drive sprocket 126 is located on the clutch shaft 128 and is keyed thereto.

Sprocket chain 130 travels over sprockets 124 and 126. While we have shown sprockets and sprocket chains transmitting continuous motion from the main drive shaft 198 to the clutch shaft 123 any other suitable means may be used to accomplish this result.

Sprocket 124, located on the main drive shaft 108, turns the magnetic clutch 134 continuously. Crank arm 132 only moves when the magnetic clutch 134 is energized. The magnetic clutch 134 is energized when the switch cam 136 (shown in FIG. 4-) operates starting switch 138.

The switch cam 140 (see FIG. 5) makes one complete turn and de-energizes the magnetic clutch 134 by bumping the stop-switch 14-2. During this one complete turn of the crank 132, ratchet 120 is partially rotated, thereby properly automatically indexing the trays.

As mentioned hereinbefore, when the carriages 60 travel outwardly, they move at a rate of speed. equal to or faster than the belt 32 travels over pulley 34. The speed at which conveyor belt 32 travels is at least equal to the speed at which cigarettes are received from the deflector 4. When the carriages 60 are traveling outwardly in this manner, no cigarettes are being delivered downwardly by the belts 32 and 68 but the cigarettes are accumulated during this interval.

It is during this period: of travel that the full trays supported on the carrier sprocket 96 are indexed in the manner hereinbefore described so as to present an empty set of trays under the vertical delivery runs of belts 32 and 68 guided over the rollers carried on the vertically reciprocable carriages 62.

During that interval of time when the trays are being indexed and the carriages 6t) are moving outwardly the carriages 62 can remain stationary relative to carriages 60 or they can continue to move up at their constantly uniform rate of upward movement. When the empty trays 82 are in position to receive cigarettes the carriages 62 "are driven downwardly until their lower end reaches a plane near the bottom of the empty tray 82. During this downward movement into the empty tray, it is desired that no cigarettes be delivered from the belts 32 and 63. This can be accomplished if the downward motion of carriages 62 takes place after the empty tray has been indexed into position but during the latter portion of the outward motion of the carriages 60. No cigarettes will therefore be delivered by belts 32 and 68 because they are still accumulating along the top run of belt 32. This may also be accomplished if the downward motion of carriages 62 begins after the trays have been indexed and at the time carriages 60 begin their inward travel, then carriages 62 are driven down at a speed equal to or greater than twice the linear speed of belts 32 so that no cigarettes are delivered by belts 32 and 68 because they accumulate between these belts as they extend down into the empty trays.

While the collecting apparatus used to illustrate our invention has been shown to consist of two pairs of parallel belts to fill two trays simultaneously, it will be appreciated that only one pair of parallel belts need be employed for filling one tray at a time as the cigarette machine discharges cigarettes in a single column, or if desired, a multiple unit of more than two pairs of parallel belts could be employed for filling more than two trays at a time where a similar number of rows of cigarettes are formed by a cigarette making machine.

From the foregoing description, it will be apparent that we have provided an apparatus which can be readily employed with cigarette trays of whatever design a manufacturer prefers and it does not require trays of a special design. One merely has to set the distance the horizontal carriages 6t and vertical carriages 62 are reciprocated. It will also be noted that the automatic tray loader is of such design that it allows for easy visual or mechanical inspection of the cigarettes while they are on top of the horizontal runs of belts 32 and that the cigarettes are not subjected to any undesirable stacking, squeezing or rolling actions in the type of apparatus we have disclosed.

The invention hereinabove described may therefore be varied in construction within the scope of the claims, for the particular device selected to illustrate the invention is but one of many possible embodiments of the same.
