10 Claims. (Cl. 198-31) of the character described which will distribute the arti-' cles from a single line rapidly and accurately to provide the plurality of lines desired, which plurality may be any odd or even number Within the operating range of the mechanism.

A further object of the invention is to provide a can dividing or distributing mechanism which is' of simple construction, reliable and accurate in operation, and adapted to operate at a high speed.

A more specific object of the invention is to provide an improved can dividing or distributing mechanism of the type which makes use of a rotary can dividing or distributing wheel having pockets in its periphery to accommodate the cans to be divided or distributed and so arranged in relation to means for bringing a single line of cans to the wheel and means for conducting multiple lines of cans away from the wheel that the cans supplied to the wheel from the single line tend to impart operating rotational movement thereto.

Another object of the invention is to provide a novel and eflicient rotary wheel type of can dividing or distributing mechanism in which cans are received in open peripheral pockets of the wheel from a single supply line are retained in such pockets until they have been moved by rotatation of the wheel to the particular places at which they are to be discharged from the wheel to provide the desired multiple outgoing lines, whereupon they are released and are discharged from the rotating wheel.

Other objects and advantages of the invention will hereinafter be pointed out or will become apparent from the following description of practical embodiments of the invention. as shown in the accompanying drawings, in which:

Patented Apr. 2, 1957 Fig. 7 is a cross-section through the governor mechanism on the line 7-7 of Fig. 5;

Fig. 8 is a vertical cross-sectional view of a mechanism embodying the invention in a form adapted to divide or distribute upright cans from a single incoming horizontal line so as to provide a plurality of horizontal outgoing lines, the view being taken on the line 88 of Fig. 9; and

Fig. 9 is a horizontal cross-sectional view of the form of mechanism shown in Fig. 8, the view being taken on line -9 of Fig. 8.

The form of mechanism shown in Fig. 1 comprises a can dividing or distributing wheel, generally designated 10, mounted to turn about a relatively fixed horizontal axis, as on a fixed position horizontal supporting shaft 11. Shaft 11 and wheel 10 thereon are located so that the periphery of the wheel turns beneath the lower discharge end of an inclined chute or rollway 12 for cans l3 and also directly above the upper receiving ends of a series of outgoing or delivery chutes or rollways for the cans. These outgoing chutes or rollways are five in number in the example shown and respectively are designated 14, 15, 16, 17 and 18.

The can dividing or distributing wheel 10 comprises a pair of circular discs, Mia and 10b, Fig. 2, rigidly connected together in spaced apart parallel relation, as by suitable cross connectors represented by the dotted small circles indicated at 19 in Fig. 1. Any suitable known means to connect the discs together so that they will turn as a unit on the supporting shaft 11 may be employed, the arrangement to be such as to provide an open space between the peripheral edge portions of the discs slightly wider than the length of the cans to be divided or distributed, so as to permit entry of rolling cans from the rollway 12 into such space. The bottom of rollway 12 may be extended as indicated at 12a, Figs. 1 and 2, so as to conduct each of successively leading cans 13 downwardly into the upper part of the wheel 16 until the can is in a peripheral portion of the wheel that has passed its upper dead center position. Such can will then be in position to be supported by and between two angularly spaced adjacent pairs of aligned pins 20 which project from the inner faces of the wheel discs toward each other so that their projecting ends are spaced apart a distance less than the length of the cans to be divided or distributed by the Wheel. See Fig. 2. Can marked X in the upper part of Fig. l is in the position just described.

The pairs of pins 29 are located on a circle spaced radially inward from and concentric with the periphery of the wheel. Adjacent pairs of pins 28 are spaced apart a distance which is less than the diameter of the cans but is substantial so as to provide an open pocket between each two adjacent pairs of pins in which a can will be seated when delivered thereto from the rollway 12, as in the case of the above mentioned can marked X.

Pockets thus provided in the periphery of wheel it) are suflicient in number to provide a plurality-four in the example shown-consecutive series or sets of five angularly successive pockets each, the pockets of each, such series or set corresponding in number to the out-.

going chutes 14 to 18, inclusive, and being indicated at 21, 22, 23, 24 and 25, respectively, in Fig. 1.

Single cross pins obviously may be used instead ofpairs of spaced apart, aligned pins 2%, in which event the chute bottom extension 12a would be shortened enough to clear the cross pins as the wheel it) rotates.

With the exception of pockets 21 which, in the particular embodiment of the invention shown in Fig. 1, require no such holding means, the can-accommodating pockets of the rotary distributing wheel are provided with releas able individual can latching means, each of which is actuated by a stationary cam to permit a can-to enter its;

energetic pocket from rollway 12 when thatpocket is at the-top of the wheel and also actuated again by a second stationary cam at the proper place to release the can in its pocket for discharge into the intended outgoing or delivery chute. The individual can latching means are alike except for features of their release means which hereinafter will be explained.

One of the wheel discs, as disc a, is provided with holes 26 opening into one end of

pockets

22, 23, 24 and 25, respectively. A can latching presser pin 27 projects from the inner side of the free end portion of a i-atch bar 28 which is pivotally supported at its opposite end, as at 29, on a bracket 30 which is fixed to the outer face of the disc Illa radially outward from the associate hole 26 so that spring means, indicated at 31, Fig. 2, which urges the bar 28 toward the limit of its pivotal movement toward the disc 1011, will tend to maintain the presser pin 27 projected through the hole 26 into the communicating pocket. If a can 13 is in that pocket, as shown in Fig. 2, when the presser pin is projected inwardly from a retracted position, indicated by dot-anddash lines in Fig. 2, the presser pin will be pressed firmly against the end wall 13a with which such can is provided and this will tend to press the can as an entity against the inner face of the opposite Wheel disc and therefore reicasably retain the can in its pocket. The can may have its end wall 13a fixed in a relatively countersunk position in the end of the can body, leavinga projecting end Wall 1312 into which the presser pm projects. The end pressure exerted by the spring pressed pin on the can therefore need not be enough to preclude all shifting movements of the latched can in its pocket during all conditions of service as lateral contact of the projected pin with the inner face of the projecting can end portion 3.35 will prevent premature or unintended displacement of the can from its pocket even though it may shift about more or less therein as the wheel 10 rotates.

The pivoted bars 28, in addition to carrying the presser pins 27 projecting from the inner face of their free ends, as shown for one of these bars in Fig. 2, carry pro ecting

release bars

32a, 32b, 32c or 3211?, Fig. 1, these bars being of different lengths for the can latching devices associated with the

pockets

22, 23, 24 and 25, respectively, but otherwise being alike. Reiease bar 32a for the latching devlce associated with pocket 22 is shorter than release bar 32b for pocket 23, etc., the release bar 32d for pocket 25 whidh is the last of the series being the longest. Each of the release bars may be spaced outward from the outer face of its bar 23 by a spacer block 33, Fig. 2, such spacer block and one end of the release bar being fixed to the free end of the pivoted bar 28 as shown in that view or in any other suitable known manner. A cam follower 34 is fixed on the inner face of the opposite, free end of each release bar. The cam follower 34 of the respective can latching devices associated with

pockets

22, 23, 24 and 25, respectively, are actuated at appropriate times and places in a cycle of rotation of the wheel 10 by individual fixed position cams to bias the pivoted presser pin bars 28 outward to withdraw the presser pins from such pockets.

An upper cam. plate 35 is mounted adjacent to the outer face of wheel disc 10:: directly above the axis of rotation of the wheel 10 in a position such that the cam follower 34 on the release bar of each of the individual can latching devices will ride up an inclined cam surface or ramp 35;: at the end of the cam plate facing counterclockwise as viewed in Fig. 1 as the pocket with which that latching device is associated approaches its can receiving position and then will ride on a constant level surface 35b of that cam. plate so that the can latchingpresser pin 27 of that device will be held in its outwardly retracted position until a can from the supply rollway has entered the pocket. The place of entry of such can into the pocket preferably is slightly beyond the upper dead center position of that pocket so that each cancntering-a pocket will aid'rotation of the-wheel. 'Ihe cam follower then will-ride ofii the opposite end of the cam plate 35, thus permitting projection of the presser pin of the latching device to its can-latching position.

In the example shown, cam plate 35 is carried by an upwardly extending arm 36a on a hub 36 which is fixed on the stationary shaft 11 outwardly from the disc 10a.

Hub 36 also has a depending arm 36]) which carries an arcuate cam plate 37 which is formed to provide at the end thereof facing counterclockwise a series of inclined cam surfaces or

ramps

38, 39, 40 and 41, respectively, these being at different radial distances from the axis of rotation of the wheel 10 corresponding to the radial dis tances from that axis of the cam followers 34 of the latching devices for pockets'25, 24, 23 and 22, respectively. The

inclined cam surfaces

38, 39, 40 and 41 are located at angularly different places along the lower part of the path of travel of the pockets of the wheel so that these cam surfaces and the immediately following portions of uniform level plane surface 42 of the cam plate 37 will act through the cam followers on the release means of the cam latching devices for the

pockets

25, 24, 23 and 22 of a series to effect release of the cans therein from the latching devices so that such cans will drop into the open upper ends of outgoing chutes-15, 16, 17 and 18, respectively.

The wheel 10 has four consecutive sets of five pockets 21 to 25, inclusive. In passing beneath the lower delivery end of supply chute 12, these pockets will be supplied in consecutive order with cans rolling into them from such chute. Each can on entering its pocket and thereafter until it is discharged therefrom or has reached the lower dead center position of the pocket will tend to impart an operating rotational movement to the can dividing or distributing wheel.

The unflatched can carried by the leading pocket 21 of a series will be restrained against outward displacement therefrom, if need be, by a suitably positioned guard rail 43 extending along the periphery of the wheel from above the delivery end of the supply chute to the outer side of the entrance of chute 14. The can then will be free to drop into that chute. The can in the next pocket, i. e. pocket 22, has the shortest release bar of the set of can-latching devices and hence, in the operation of the particular assembly of elements shown in Fig. 1, will be retained therein until the entrance of outgoing chute 18 has been readhed and then released to drop into that chute. Cans from pocket 23 will be released to chute 17, cans from pocket 24 will be released to pocket 16 and cans from pocket 25 will be released to pocket 15.

The mechanism as just described may be used with either filled or empty cans. If the cans are empty and are closed at only one end, they must be arranged with the closed end'thereof turned to face the disc 10a as at the time they are deposited in the peripheral pockets of the rotating Wheel. This may be done by suitable twister conveying mechanism, not shown, arranged to precede or form a part of the incoming can chute or rollway 12.

The cans delivered to the rotary can dividing and distributing wheel will impart rotation thereto with the arrangement described. It may be desirable, however, to equip this Wheel with a means to regulate or control rotation thereof so as to assure-desirable uniformity of speed and smoothness of rotary movement as well as ability positively to regulate the speed of and stop the rotation of the wheel when this is desirable.

Fig. 4 shows one form of rotation control means for the wheel, this being a friction drive wheel 44 supported, as by supporting structure indicated generally at 45, for r0- tation with its peripheral surface bearing against the outer face of disc 10bof the wheel 10 to impart a rotary motion to the wheel 10 in the desired direction at a uniform speed'determined by. the peripheral speed of the wheel 44 when the latter is rotated; Wheel 44 may have a driven connection, represented, by the chain and sprocket arrangement generally designated 46 in Fig. 4, with a motor and gear reduction unit designated 47. Unit 47 may be supported on the supporting structure 45 and may of course be started and stopped at will.

Instead of the motor driven speed control appliance shown in Fig. 4, Wheel 10 may be equipped with either or both of a brake mechanism generally designated 48 and a governor generally designated 49, both shown in Fig. 5.

Brake 48 comprises an arm 50 pivota lly supported at one end, as at 51, on a suitable support 52 which may form part of the structural support for the wheel supporting horizontal shaft 11. The arrangement is such that the pivoted arm 50 may be swung about the axis of its pivotal connection with support 52 toward and away from the bottom of a peripheral V-groove 53 (see Fig. 6) of a brake wheel 54 which is fixed to and coaxial with the wheel 10. A brake shoe 55, which is made of compressible material such as rubber and is of V-shape in crosssectional configuration to match the cross-sectional configuration of brake wheel groove '3, is fixed to the inner side of swingable arm 50. When the latter has been swung toward the axis of rotation of the brake wheel, the brake shoe will be compressed by the sides of the V- groove of the brake wheel to exert a braking action adequate, if desired, to stop rotation of wheel 10. The opposite end of pivoted swingable arm 50 is connected adjustably by an adjusting connector 56 with one end of a coil spring 57, the opposite end of which is connected to the movable element 58 of a solenoid 59, which is supported in a relatively stationary position, as by an overhanging arm 6t attached to the top of the supporting member 52.

The brake wheel 54 may be connected to the adjacent disc lob of the wheel to rotate therewith in any suitable or preferred manner, as by rigid connectors such as that indicated at 61 in Fig. 6.

The adjustment by element 56 of the spring link 57 with pivoted arm 50 may be such that the brake shoe 55 wilt be completely disengaged from the brake wheel groove when the solenoid is deenergized, the coil spring link 57 then being free from tension. With this adjustment, energization of the solenoid will pull the brake shoe arm toward the periphery of the brake pulley so as to stop rotation of the can dividing and distributing wheel 10. A suitable known electric circuit, none shown, may be provided to energize the solenoid whenever a condition arises which makes stoppage of the wheel 10 desirable. Thus, a suitable known photoelectric signalling device and operative connections to the solenoid may be provided and arranged to energize the solenoid and stop the rotation of the wheel 10 whenever there is a gap or discontinuance of the line of cans rolling down the supply chute 12 to the pockets of the wheel 10. Alternatively, the adjusting device 56 may be adjusted to put the spring link 57 under sufficient tension to cause the brake shoe 55 to exert a predetermined drag on the brake wheel when the solenoid is de-energized and thus tend to retard rotation of wheel 10 and make it more smooth and regular. Stoppage of the rotation of the wheel 10 would be efiected in the manner described, that is, by energization of the solenoid.

The governor 49 comprises a rotary wheel 62 arranged to hear at its periphery against the face of disc 10b of the wheel 16 so as to be driven by rotation of the latter. Driven wheel 62 is mounted operatively, as on a bracket 6.) attached to the support 52. Rotation of wheel 62 by rotation of the wheel 10 will cause motion to be transmitted through a suitable transmission generally indicated at 64 to a vertical spindle 65 which depends into a con,- tainer 66, suspended from the bracket 63. Container 66 is adapted to hold a viscous fluid, such as oil 67, Fig. 7, against which vertical vanes 68 on the submerged portion of spindle 65 will act when spindle 65 is rotated about its axis by the means and in the manner described. This will oppose resistance to the rotation of wheel 10 so as to retard and stabilize or. render uniform the rate of such rotation. The retardation of the rotation of wheel 10 by the device 49 may be varied by filling the container 66 so as to submerge the vanes 68 more or less with a fluid of a given viscosity according to the amount of retardation desired. The container may have a valved bottom outlet such as indicated at 69 in Fig. 5 for convenience in regulating the level of the retarding fluid in the con tainer. The regulation of such retardation could, of course, be efiected by using oils or other suitable fluids of different viscosities.

An embodiment of the invention adapted and intended for use with cans in upright position, indicated at 113, is shown in Figs. 8 and 9. These cans are brought in a single line on a horizontal conveyor 114 moving in the direction indicated by the arrow thereon in Fig. 9. The incoming cans may be guided in a lane 112'defined by parallel guide strips 115 and 116, respectively. Guide strip 116 extends above a marginal edge portion of conveyor 114 and may be extended past a can dividing and distributing wheel generally indicated at 110 so as to serve in cooperation with a spaced parallel strip 117 to provide an outgoing lane 118 for cans at the opposite side of the wheel 110 from incoming lane 112. Other outgoing lanes, indicated at 119, 120 and 121 are provided above the horizontal conveyor 114 at the opposite side of Wheel 110 from lane 112 by suitably spaced parallel guide strips 122, 123 and 124, respectively.

As shown by Fig. 8, wheel 110 comprises a horizontally disposed disc 110a attached to the lower end of a rotary suspending shaft 125 which is journaled in and supported by a suitable bearing structure 126 which is mounted on a cross frame 127 carried by uprights 128. Disc 110a carries a circular series of depending pins 129, adjacent pins being spaced apart a distance less than the diameter of a can 113 and the pins being located in a circle spaced radially inward from the periphery of disc 110 preferably somewhat greater and not appreciably less than the diameter of such a can. The wheel 110 thus is provided with consecutive sets of pockets indicated at 130, 131, 132 and 133, respectively. The number of pockets of each such set corresponds with the number of outgoing lanes 118 to 121, inclusive, and three of the four pockets of each set are provided with individual releasable can latching devices, respectively, indicated at 134, 135 and 136.

Each

device

134, 135 or 136 is substantially like the t can latching device for the embodiment of the invention shown in Fig. 1. It' therefore will sufiice to state that each such device includes a spring loaded pivoted latch pin arm 137 mounted on the upper face of wheel disc 116a and urged continuously toward such disc so that a can presser pin 138 carried by the pivoted arm 137 is urged through a hole 139 in disc 110a to position to bear against the end closure 113a within the confines of the projecting upper end portion 113!) of the can body so as to'retain the can in its pocket during rotation of the wheel 110 until presser pin 138 has been raised above the level of can end 11312. For raising the presser pins 138 of the severe! latching devices in their turn to admit cans to and sub-' sequently release the cans in the associated pockets, stationary cam plates 140 and 141 areprovidedand formed appropriately for coaction with cam followers 142 carried by different length releasezarms 143,144 and 145 which are carried by the pivoted arms 137 of the

can latching devices

134, 5135 and 136, respectively.

As shown, stationary cam plate 140 projects from a hub 146 having a bearing 147 through which a portion of the vertical shaft extends and in which such shaft may turn 'freely. Cam plate 140 may be connected with over-' head frame member 127 by arigid suspension element 148.

- With the wheel 1 10 rotating counterclockwise as indi, cated by the arrow in Fig. 9, the cam followers 142 of the

several latching devices

134, and 136, respectively; will ride up an inclined cam surface 141a at the proximal side of the catn plate so as to raise the presser pins;

1.38, of the. can latching devices above the leveliof the. tops, of the cans entering the pockets inturn from; the lane, 112. The presser pins 138 will be kept raised until the cam follower elements of such devices are moved off the opposite edge of the cam plate 140 and. the latching; devices will then automatically clamp down on the cans in the underneath pockets. The pocket 130 does not have a can latching device and the can carried thereby will be discharged into the first encountered outgoing lane, which is 118. The cans in the other pockets will be held therein until the latching devices associated with such pockets are actuated to release them. This will occur for the pocket 131 when the cam follower 142 of its latching device rides up an inclined surface 141a of a stationary cam plate 141. Stationary cam plate 141 projects from the hub 146 at the opposite side of the axis of rotation of wheel 11% from cam plate 140 and is suspended from cross frame member 127 by suspension elements 149. This will permit cans from pocket 131 to pass into the more remote of the outgoing lanes, which is lane 121. The cans from pocket 132 will be released for entry into lane 120 when the cam follower 142 of its latching device rides up an in clined surf-ace 141]) of cam plate 141. Likewise, each can in the pocket 133 will be released to enter its lane, which is lane 119, when the cam follower 142 of its latching device rides up inclined surface 1410 of cam plate 141,

The rotation of the wheel 110 will be effected by the cans entering the pockets thereof from the supply lane 112 and the speed thereof will, of course, depend on the speed of linear movement of conveyor 114.

Obviously many modificationsof and changes in the illustrative embodiments of the invention shown in the drawings will now become apparent or readily occur to those skilled in the art and I therefore do not wish to be limited to the details of these illustrative embodiments.
