23 Claims.

This invention relates to an improved apparatus for rearranging rolling cans from a single line into three lines. In the handling of canned goods, such as canned food products, after the filling and proc-,

essing operations are completed, the cans are labeled and then packed in suitable cases for shipment such as corrugated board or fibreboard shipping cartons. The labeling is done by means of a labeling machine through which the cans roll in a single line but most packing machines require that the single line of cans leaving the labeling machine be rearranged into a plurality of lines so as to facilitate the forming of the charge and placing of it in the shipping case.

A single row or line of cans is'readily rearranged into two lines or any multiple of two lines by means of a can divider or distributing mechanism which is provided with can-deflecting means which is shiftable by the cans themselves so as to deliver alternate cansinto either of two lines. Such mechanism has not customarily been employed for rearranging cans from a single line into three lines or a multiple of three lines because of the difiiculty in obtaining an equal distribution of the cans among the three lines. Can distributing mechanism of this type is frequently referred to in the industry as star wheel divider mechanism because of the fact that the can-deflecting member is in the form of a portion of a star wheel. 7

The primary object of my present invention is to provide a can-rearranging or distributing mechanism of the star wheel divider type which is capable of rearranging a single line of cans into three lines having an equal average distribution of the cans between them so that cans may be removed from each of the three lines at the same rate, that is to say, the same quantity may be taken from each of the three lines per unit of time.

A specific object of the invention is to provide a can-distributing mechanism for supplying cans to a case packing machine for placing the cans in shipping cases in which the cans are stacked in three superposed rows and then pushed endwise into the case.

Another object of the invention is to provide a can-distributing mechanism of a particular construction which is capable of use in distributing cans into three rows with either an equal or an unequal average distribution, that is, of general application.

The invention will be understood from a consideration of the accompanying drawings which of the invention in a case packing machine.

Referring now to these drawings:

cated generally by reference numeral 3.

Fig. 1 is a view in side elevation of the improved can-rearranging or distributing mechanism applied, to the runways of a case packing machine which is adapted to insert a charge of cans consisting of three rows of four cans each into the packing case;

v Fig. 2 is an enlarged view of the can-distributing mechanism shown in Fig. 1 with the front side plate thereof removed; and a Fig. 3 is a diagram of the electrical connections and also illustrating a vertical section taken on line 33 of Fig. 1, drawn to an enlarged scale, showing the can gate or stop mechanism.

Referring to Fig. 1, the case-packing machine comprises a frame l which supports packing mechanism indicated generally by reference numeral '2 and a can runway or track section indi- The packing mechanism 2 comprises 3 superposed shelves :3 which receive the cans to be packed from the three superposed runways 5.

After a charge comprising 12 cans, four on each of the three shelves Kl, has been received by the packing mechanism, a set of plungers 5, carried by a common head or carriage, are advanced and push the cans forward in the direction of their axes through a funnel l on which the case to be packed has been telescoped. This motion of the plungers 6 ejects'the charge of cans into the packing case on the funnel and the weight of the cans causes the case to be lowered by means of a drop-off arm 5 which is pivoted on a shaft 9 and causes the filled case to be turned through an angle of to upright position and deposited upon a conveyor (not shown) by which the filled cases are carried to the next operation, usually that of closing, gluing and sealing the flaps ready for shipment.

'The head or carriage for the packing plungers 6 is indicated generally by reference numeral ill and is reciprocated by a pair of arms H, the lower one of which carries a cam roller [2 which engages a face cam l3. This cam is rotated by means of an electric motor l4 through suitable reduction gearing I5 and control mechanism (not shown). This brief description of the packing mechanism is believed sufiicient for present purposes and further details thereof may be found in Kimball, Braren and Schaefer Patent 2,127,924,

granted August 23, 1938, to the assignee of the present application.

Suitable gate mechanism, indicated by numeral means II and II of the star wheel divider" type and a can-switching device or means 20,.together with a can feed stop mechanism 2| illustrated in Fig. 3. These various devices are all mounted or assembled between two

parallel plates

22 and 23, the rear plate 22 being illustrated in Fig. 2 and the front plate 22 in Fig. 1. These plates are mounted in fixed relation and spaced apart from one another slightly more than the length or height of the cans which the apparatus is to handle so that the cans when lying on their sides may move freely between these plates.

Each of the can-deflecting devices i8 and I9 comprise a pair of members in the form of a portion of a star wheel and fixed in alinement with one another to their respective supporting.

shafts

24 and 25. These shafts are mounted for free oscillation in suitable bearings carried by the

side plates

22 and 23 and their construction and operation is illustrated and described in detafl in the aforementioned Letters Patent 2,127,924. The pairs of star wheel members constituting each of these can-deflecting devices are spaced apart on their supporting

shafts

24 and 25 sufhciently so that they will engage the beads of the cans rather than the can bodies.

It will be understoodthat each of these candeflecting devices i8 and I 9 is shiftable by the passage of the cans to either of the two positions shown respectively in full and dotted lines in Fig. 2. Hence when a can descends from the switching device 20 onto can-deflecting device l8, it will be diverted or deflected to the right, and while moving past the right hand side of can-defiectingcievice ill, will shift it from the full line to the dotted line position so that the next can will consequently be deflected to the left. The can-deflecting device l9 operates in a similar manner.

Can-deflecting device I9 is positioned so as to deliver cans alternately to the lowermost can runway or track 5 and the intermediate can rimway or track 5. Can-deflecting device i 8 being disposed above and slightly to the left of deflecting device I 9, is arranged to deliver cans alternately to a point substantially above the vertical center line of the deflecting device l9 and to the uppermost can runway or track section 5.

In order to suitably guide and maintain the cans as they pass to the left of can-deflecting I devices It and I! so that they will pass suiflciently close to these devices to insure the shifting thereof, an appropriately shaped can supporting plate- 26 is provided .which extends between the side plates 22 and is carried by these plates. Similarly supported

guide plates

21 and 28 deliver cans .from deflecting members is and I8, respectively, to the intermediate and uppermost runways 5.

The can-switching device 20 comprises a pair of downwardly directed

parallel plates

29 and 20 which are pivoted at their upper ends to swing freely between the

side plates

22 and 23.

They are maintained in parallel relation by means of a pair of links ll arranged on the outside of

plates

22 and 23 and connected to the lower ends of switch plates 22 and 2| by

pins

32 and 32 which extend through arcuate

slots llandiiinthesideplatea'Thesecanswitch plates

22 and 30 are shiftable from the full line 7 position shown in Fig.2 to the dotted line position by means of a solenoid It. The plunger 21 ofthis solenoid isconnected by ashortlink to'a bell crank lever II which is connected at its opposite end to a link 22 to switch plate 20. This leverage and linkage system is biased to the full line position shown in Fig. 2 bymeans of a helical spring I. and when thesoienoid coil 26 is energized the switch plates of switch mechanism 20 are shifted to the right in dotted position so as to deliver the cans vertically over the center line of can-deflecting device I. Right hand switch plate 3. is provided with a. curved extension ll to preserve the cans in operative engagement with can-deflecting device l8 when mechanism 20 and the can stop mechanism 2| so as to cause the can-distributing mechanism if! to produce an equal average distribution of cans among the three can runways or tracks 5. so that equal quantities of cans per unit of time can be removed from the discharge or lower ends of these runways, as, for example, by the casepacking machine illustrated in Fig. l, the canswitching mechanism 20 and the can stop device 2| are controlled by the electric switching devices illustrated in Fig. 1 which are electrically connected as shown in Fig. 3.

Mounted above the uppermost runway or track section 5 is an electric switch 44 which is provided with an operating lever 45 (Fig. 3) arranged in the path'of the cans and when this lever is raised by cans passing beneath it, switch N is closed. This switch is positioned about midway between the discharging mechanism I! and the case packing mechanism 2 so as to provide a can storage section for the packing mechanism to the left of switch It and an operating can supply section to the right of switch ll.

Also in the uppermost can runway section 5 there is arranged adjacent the can distributing mechanism- II a counterbalanced pivoted track section 46. This-track "section is pivoted at 41 and counterbalanced by an adjustable weight 48. It is connected to operate a second electric switch 49 by means of a rod 50.

In the lowermost can runway section 5 and also adjacent can-distributing mechanism ll, there is asimilar pivoted track section 5| pivoted at 52 counterbalanced by weight 53 and connected by an operating rod 54 to operate a third electric switch. 55. Both of these pivoted track sections operate in the same way; that is to say, when sufllcient cans rest upon either of the respective track sections their counterweights are overbalanced causing the right hand end of the sections to descend, thereby closing their respective electric switches 49 and 55.

Referring to the circuit diagram of Fig. 3 the holding switch 44 is in series with switch 49 so 2,312,060 that current is received from one of the supply mains 55 and passes first through holding switch 44, then through conductor 51 to switch 49, thence through conductor 58 to solenoid coil 35 for operating the can-switching device 20, and thence through conductor 59 back to the other supply line 56.

The third switch 55 receives its current from one of the supply conductors 56 and the current then passes through conductor 50 to the operating coil 6| of can stop device 2|, thence through conductor' 62 back to the supply conductors 55. The can stop mechanism 2| consists of a laterally and horizontally shiftable rod 63 which, when solenoid coil 6| is deenergized,-

is withdrawn to the left as shown in Fig. 3 out of the path of the cans. When the coil is energized, however, its plunger lifts one arm of a bell crank lever 64 against the tension of a helical spring 65 and the other arm of the bell crank lever is yieldably connected through a second helical spring 66 and a collar 61 to shift the stop rod 63 to the right, or dotted position, into the path of the cans so as to prevent their passage.

In the operation of the can-distributing mechanism a continuous supply of cans is usually fed along the main feed line 42 to the distributing mechanism l1, and, assuming that for some reason the packing mechanism 2 is temporarily not operating, the cans descend through canswitching device 20 (which is in the full line position as shown in Fig. 2) onto the star wheel divider l8 by which one-half of the cans are directed or deflected into the uppermost runway section while the other half of the cans is delivered to the second star wheel divider or candefiecting device I9, and this half of the cans is thus again divided into two sections so that oneiourth of the cans delivered through the switching device are received upon the intermediate and lowermost runway sections 5.

As the upper runway section fills with cans as far as holding switch 44, the operating member of the switch will be closed. but this does not close the circuit of solenoid 36 because balance beam operated switch 49 is still open. As the cans further collect in the uppermost runway, however, this runway will be substantially filled so that there will be sufiicient cans on pivoted shown in Fig. 2. This cuts on the delivery of cans to the uppermost runway section and causes all of the canspassing through can switch 20 to be delivered to can-deflecting device l9 so that one-half of the cans is now being sent into the intermediate runway section and the other half into the lower runway section 5.

When the cans build up in the lower runway section 5 to the point where pivoted track section 5| is forced downwardly, switch 55 i closed and this energizes solenoid 6| and causes can stop 2| to prevent the further delivery of cans from the main feed line 48.

rise, and switch 55 will be opened, thereby deenergizing coil 5| of the can stop 2| and permitting resumption of the supply of cans to the intermediate and lowermost runway sections 5. This will continue until the cans on the uppermost runway section 5 recede below the operating lever 45 of holding switch 44, at which time this switch also will be opened and cause coil 35 to be deenergized, thus causing can switch 20 to be shifted back to the full line position. Coil 35 is not de-energized by the opening of switch 49 when the cans recede from the balanced pivoted track section 46 because of the closing of holding circuit contacts 68, shown diagrammatically in Fig. 3, which are moved to closed position by the lowering of plunger 31.

In this manner the flow of cans, one-half to the uppermost runway section 5, andone-quarter to each of the other two runway sections. will ,be resumed. Hence, during the normal operation of the machine, that is to say, with the can.- packing machine removing cans from the storage runway continuously, the supply of cans on the runway sections will build up until these sections are completely filled and then will be depleted until the cans in the uppermost runway recede Assuming now that the operator places the 4 packing mechanism 2 in operation, cans will begin to be removed from the storage runway 7 of switch 44 will descend to take their place. As

soon as the cans on the lowermost runway have receded from pivoted section 5|, this section will to the left of holding switch 44 when the building up operation of the can supply on the runway will begin again. Operation in this manner willcontinue so long as cans are supplied through the main feed line 42 and the cans can be removed from the three runway sections at the same rate as they are supplied by the main feed line. Thus an equal average distribution of cans from a single feed line to three separate lines is accomplished.

While my invention has been described in connection with apparatus for handling the ordinary sheet metal cans of commerce, it is capable of, or readily adaptable to the handling of other round articles and hence the term fcan will be understood to inchide not only sheet metal cans and the like, but other round articles or objects capable of being rolled on their sides.

It will be understood that changes can be made in the arrangement of the improved mechanism which I have disclosed without departing from the spirit of the invention, the scope of which is intended to be set forth in the appended claims. Thus, for example, by properly shifting the canswitching device 20, an unequal average distribution of the cans between the three lines can be obtained. For example, any desired proportion of the cans up to one-half may be sent into the uppermost line.
