'IZ/WE 2 lqyd D, Riley INVENTOR ATTORNEYS PACKAGING METHOD AND MACHINE SUMMARY This invention relates to the art of packaging and more particularly to a machine for packaging a predetermined number of articles wherein means are provided to arrange, from a random quantity of articles, plural succession or columns of the articles and release them from each succession one at a time into a container.

The articles preferably are substantially round, as for example, citrus fruits, apples, onions and some shapes of potatoes. The more nearly round the articles are, the more eicient will be thlmachine; but, limited degrees of oblateness or deformation are easily within the capabilities of the machines func IlOIl.

AThe invention involves a mechanical system for arranging from a random supply of articles plural successions thereof and releasing one article from each succession into a container as it travels by the arrayed discharge ends thereof. The number or articles placed in the container is equal to the number of successions functioning during a particular container transit. t

It is a principal object of this invention to provide a versatile article packaging machine by means of which -a selected number of articles may be packed, varying from one to the built-in capacity ofthe machine.

Another object of the invention lies in the provision of a packaging machine having means for arranging random articles into columns or successionsfrom which the articles are released successively into plural containers moving by the discharge ends of the successions, the 'release being effected by a control mechanism actuated by the movement of each container thereby.

It is yet another object of the present invention to provide in the foregoing reference a clutch actuated rotatablewheel having plural circumferentially spaced article pockets each movable from a receiving station to a discharge station by means of incremental radial movements effected by said clutch.

A further object of my invention is to provide a novel method of disengaging meshed gears to serve as said clutch.

The foregoing and other objects and `advantages of the present invention will ybecome more apparent from the following specification when considered in association with the accompanying drawings wherein a preferred form of the invention is graphically illustrated.

In the accompanying drawings where like reference numerals are employed to designate similar parts throughout:

FIG. l is an isometric view `of the arrangingland control portion of my invention.

FIG. 2 is an enlarged sectional view taken substantially on the plane indicated by line 2-2 of FIG. 1,in the direction indicated by the arrows.

FIG. 3 is a plan view of the control mechanism shown in FIG. 2.

FIG. 4 is a front elevation taken on'a plane through the line 4-4 of FIG. 3, taken in the direction indicated by the arrows.

FIG. 5 is an 'elevation of the power transmission carried by the subframe; and

FIG. 6 is an elevation of said transmission rotated 90 counterclockwise from FIG. 5, i.e., looking'from the left of FIG. 5.

Referring now more particularly to the several views of the drawing, I have provided frame l0 having subframe '11 serving as a base for the machine.

Carried by subframe 11 are'two electric motors l2 and 13. Motor 12,'by means of V-belt 14 (FIG. 6) drives a power train, encased in housing l5, which in turn rotatesmain shaft 16. At one end shaft 16 carries sprocket 17 (FIG. 5) which drives chain 18, to rotate continuously and at a constant speed, eccentric 19 (FIG. 5) interconnected by pitman 20 to rock lever 21 and thusly to oscillate rock-shaft 22 (FIGS. 1, 5) to which floating frame 24 is connected by rock links 23 to adapt the floating frame for `rectilinear oscillations in the direction of double-ended arrow 25.

Main shaft 16 is also provided with bevel gear 26 (FIGS. l, 6) which enmeshes with companion bevel gear 27 (FIG. 6) drivingly carried by a jack shaft 28 adapted to drive eccentric 29 (FIG. 5) which, through pitman 30 effects rectilinear oscillation of laterally inclined oscillating plate 31 (FIG. 6) in the direction of double-ended arrow 32.

Frame l0 (FIG. l) carries paired side-by-side but otherwise coincident endless belt conveyors 33-33 which are inclined from their lower edges contiguous to the oscillating plate upwardly at a selected angle manually adjustably fixed by articulate linkage 34. The belts of conveyors 33-33 are trained about parallel upper and

lower belt rollers

35 and 36. The lower rollers are rotated by V-belt transmission 37 trained about pulley 38, driven by motor 13, and pulley 39, adapted to drive rollers 36 and move the top flight of the conveyor belts in the direction indicated by arrows 4040.

Contiguous to and at the side of inclined oscillating plate 3l, opposed to conveyors 33, I provide a series of parallel troughs 41-41 mounted upon floating frame 24 and thus subject to rectilinear oscillations therewith.

Each of the article supporting elements-conveyors 33 33, oscillating plate 3l and troughs 4l-is inclined so that the articles which the machine is adapted to package will roll by gravity from a random quantity placed upon conveyors 33- 33 across plate 31 to form successions or columns of articles in each trough. The various oscillations are effected to impart adequate lateral and horizontal movement in the articles to facilitate their entry into the elevated receiving ends of the troughs.

At the lower discharge end of each trough 4l, I provide a control mechanism generally comprising wheel 50 (FIGS. 1, 3) journaled for rotation about horizontal countershaft 52 extending laterally of its respective trough so as to present sequentially plural, circumferentially spaced pockets defined by adjacent radiating fingers 51-51. In the drawings I have shown fingers 51-5l, and thus the pockets defined thereby, quadrantially arranged but more or fewer may be provided, if desired.

FIG. 2 shows wheel 50 disposed after having received an orange 0 from the

succession

01, 02 on and is momentarily cradling it while controlling the gravity flow of the balance of the

succession

01, 02, on reposing in the associated trough 4l. In this position, countershaft 52 journaled in spaced arms 53-53 of tilt frame 54, is in its elevated or raised position, the wheel having just rotated clockwise past the receiving station wherein orange 0 moved by gravity, into its pocket at substantially the coincident moment the preceding orange 03 was discharged from the preceding pocket through its open mouth and into container 55 carried by plural container supporting and actuating device 56 adapted to support containers with their open mouths positioned to move along a predetermined path adjacent to the discharge ends of troughs 41 to sequentially receive articles therefrom.

In the position shown, orange 0 is intermediate the receiving station and its discharge station. This momentary resting position is effected by means of cam 57 having saddle 58 in which one of plural dogs 59, fixed to and projecting from a side face of peripherally toothed gear 60, is supported. Gear 60 is drivingly carried by countershaft 52 and in said intermediate position, the peripheral teeth of gear 60 are held disengaged with respect to companion gear 6l drivingly connected to driving shaft 62 which is constantly rotating, being driven from shaft 16 by V-belt transmission 63.

Cam 57 is fixed to lever 64 pivoted at its inner end for horizontal rotation about the vertical axis of pin 65 and is yieldably held in the position shown in FIGS. 2, 3 and 4, by tension spring66. When lever 64 is momentarily moved in the direction of arrow 67 (FIG. 3), cam S7 is shifted in .the same direction (arrow 68, FIG. 4) out of supporting relationship to dog 59.and tilt frame 54 is permitted to drop by gravity, engaging

gears

60 and 61 and thus driving wheel 50 by the receiving and discharge stations to discharge one orange 0 and receive the next successive orange 0l, whereupon the next successive dog 59 contacts cam 57, to elevate tilt frame 54 and thereby disengage the meshing teeth of

gears

60 and 61 simultaneously with the dog 59 becoming captured by saddle 58.

At the outer end of lever 64, I provide axially vertical sleeve 67 in,which is journaled one leg 71 of U-shape member 70 which is yieldably held in the position shown by tension spring 66 attached at point 68 spaced from the axis of leg 71 to apply biasing torque to maintain the position shown. When finger 80 of container support and actuating device 56, moving along its course of transit, strikes outer leg 72 of the member 70, it shifts the lever as hereinbefore described and thence the member may pivot about the axis of leg 7l to further shift leg 72 as indicated by arrow 73 and thus provide a lost motion or yieldable connection to allow for necessary clearances between moving parts. g

In FIG. 1 it is seen that I have provided a series of troughs 41, each with its control mechanism 50-72. It should also be understood that the container support and advancing device will carry plural containers 55, each having its associated actuating finger 80 disposed to effect discharge of an orange into the container from successive troughs 41 until the desired number of oranges have been contained. The quantity may be variable up to the number of troughs 41, each of which holds one succession, by blocking entrance to the troughs. For example, if only three troughs are open, only three oranges will be placed in each successive bag 55.

lt should be seen that while I have described this invention in relation to oranges, the term articles is employed to include any and all items which can be handled like the descriptive oranges. Furthermore, I do not wish to be limited to bags as the packaging device and therefore employ the term containers to include any and all operable devices for containing articles that are subject to the practice of this invention.
