14 Claims.

This invention relates to a machine for converting a single line of articles into. a plurality of lines.

An object of the invention is the provision of a machine which is adapted to receive. a single line of articles with means therein for moving alternately disposed articles intov one track of a double track and for moving the other articles into the second track sov that when the articles emerge. a. double line of articles will be discharged to facilitate rapid packing of the articles in boxes.

Another object of the invention is the provision of a machine having means therein for transferring cans from a single track to a double track with the double track continuing to a discharge. point so.- that a double line of cans will emerge. to facilitate. the rapid packing of the cans in containers for shipping purposes, means. being employed for moving the cans along the single path after the cans have entered the machine. and for moving the cans along the double path, the moving means being employedfor operating a plurality of shifting means for alternately placing the cans in the double track.

A further object of the invention is the provision of a machine for converting a single line of cans or other articles into a plurality of lines with means for moving the cans in the single line toward and through the plurality of lines or paths, said moving means being adapted to alternately operate a plurality of shiftable means for forcing the cans in alternation from the single line into a plurality of lines, the single line of cans being supported in a machine by a flexible strip which may be depressed by a can when'it has been engaged by an element of the moving means and when the can is forced directly downwardly instead of being carried along its definite path.

A further object of the invention is the provision of a machine for converting a single line of cans into a plurality of lines with means incorporated in the path of travel of the cans both in the single and plurality of lines, for stopping the operating parts of the machine when the cans are crowded along" the plurality of lines or when the cans fail to follow in successive order along the single line.

This invention will be best understoodfrom a consideration of the following detailed. description, in view of the accompanying drawings forming a part of the specification; nevertheless, it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes. and modifications as define no material departure from the salient-features. of the invention as expressed in the appended claims.

In the drawings:

Figure l is a plan View of the machine constructed according to the principles of my invention.

Figure. 2 is a vertical section ing parts in side view.

Figure 3 is a front view of the machine with parts removed and partly in section.

. Figure 4 is a transverse. vertical section taken along the. line 44. of Fig. 2.

Figure 5 is a. view in perspective of the can shifting means shown in detached relation.

Figure 6 is a view in elevation of the operating means for the can shifting elements shown partly in section.

Figure 7 is a fragmentary longitudinal section taken along the line 1-1 of Fig. 1.

Figure 8 is a transverse vertical section taken along; the. line 88. of Fig. 1.

Referring more particularly to Figs. 2, 3 and 4 it will be seen that a framework generally designated by the numeral [0 is formed of. angle irons secured together and forming a base for supporting the machine. The base includesv a pair of horizontally disposed bars H running longitudinally of the base and connected together by rods 1.2 and 13. Pairs of. diagonally disposed reinforcing bars l4 and. 15 are located at each side of the base member and these bars are connected intermediate; their ends to reinforcing bars I6. The upper ends of the bars are connected to the adj acently disposed horizontal bars I l and extend downwardly at an acute angle to each other. Legs I l and I8 extend downwardly at right angles from the ends of the bars [I for supporting the machine above the floor. While one particular form of support is illustrated and described many variations may be employed for the purpose.

A housing generally designated by the numeral 20 consists of a front plate 2|, rear plates 22,

side plates

23, 24 and a. cover plate 25. The front wall 2! is provided with a door 26 which is hingedly connected at 21 to a transverse bar 28 at the lower end of the housing.

A reinforcing framework is located Within the housing and secured to the various plates or walls thereof. This framework consists of pairs of front angle irons 30 and pairs of rear-angle irons M to which the front, rear and side walls are secured. At spaced

points bars

32, 33 and 34 are secured to the angle irons 30 and 3|. As will be presently explained other pairs of spaced angle showing the

workirons

35, 36, 31, 38 form part of the double tracks through which cans are carried to a discharge table 39 and these bars aid in reinforcing the framework. Biased bars I3a are located at each side of the housing 20 and are connected at their upper ends to the bars 33 while the lower ends are perforated to receive the transverse rod It will also be noted that transverse bars 40, 4i; 42, and 43 are secured in spaced relation to the framework whichis enclosed within the housing 20.

which roll out onto a table or platform 39 and are carried away by a pair of runways generally designated by the numerals 44 and 4411.

Two

inner pairs

45 and 46 of tracks are located in spaced relation with the tracks 35 to 38 inclusive and the inner tracks are in line with'the' last mentioned tracks. The outer tracks 35 to 38 inclusive have the respective flanges 35a, 36a and 31a, 38a extending above the upper termini 41 of the tracks 35 to 38 inclusive. The upper termini 41 of the last mentioned tracks are in alinement with the platform 39 and the discharge tracks 44 and 4441 as shown more particularly in Figs. '2 and 4. The reason the tracks 35 to 38 inclusive are cut away is to permit the cans gen erally designated by the numeral C to roll.out over the table 41 and ontothe tracks 44 and 44a in pairs while the, side flanges 35a to 38a inclusive maintain the cans in the proper upward position so that when'they are discharged they will roll onto the respective tracks 44 and 44a. The lower ends of the

inner tracks

45 and 46 which are located within the machine are cut away along one flange at a point indicated by the numeral 49 (Fig. 4), thus leaving a single side flange on the outer members of the

tracks

45 and 46 as shown at 50 for engagement with the end closures of the cans C.

The cans are fed through an opening. (Fig. 2)

' atthe front of the machine and below a lip from a-single inlet track generally designated by the numeral 52 which is hingedly mounted upon cars 53 secured to a U-shaped bar 54 located transversely of the machine and secured to the side bars IL:

A pair of spaced plates 55 are securedto angle irons .56 and 51. These angle irons are secured in any well known manner to the frame and housing of the machine. The angle irons extend inwardly and terminate at a point adjacent a vertical plane passing through the longitudinal axis of a shaft 59.

A curved metal member 60 is secured to a transversely disposed angle iron 6| at itsupper rear end. This curved member has a base portion 62 upon which the cans are adapted to ride and a pair of vertically disposed side flanges 63 The space between the bars 40 and 4l is left open to provide openings 48 for the cans as shown in Figs. 2 and 4. The ends of the cans asingle path in alternation to the double path which leads from the machine.

. A As shown more particularly in Fig. 2, a flexible supporting member is hingedly mounted at ibl e ,member extends downwardly beneath the lower edge of the angle irons 51 and is carried beneath the undersurface of the curved member 60. A pair of coil springs 61 are secured to the inner end of the flexible member and eye bolts 88 connect the outer ends of the springs with the transverse rod l3. These bolts are threaded after passing through perforations in the bar l3 and a nut 69 on each bolt is adapted to increase or decrease the tension on the springs and likewise on the flexible member when the nuts are adjusted. The flexible member 65 serves a particular purpose and acts as a single track to receive the incoming cans before they are moved to the double tracks as will be presently explained.

Shifting elements for moving the cans in alternation from the single track on the flexible member .65 to th double discharge tracks is illustrated in Figs. 2, 4 and 6. A fixed cylinder generally designated by the numeral 10 is provided with a pair of cam tracks II and 12 at the surface thereof. These tracks extend around the cylinder in opposite directions with the portions of the respective cam tracks which are indicated by the numerals l3 and 14 being located close together at the rear portion of the cylinder and where the cans C are positioned at their outermost limits either to the right or to the left of the machine as shown in Fig. 4, and where the cans are in a positionto be carried either to one their ends to a pair of disks 11 which have their hubs 18 rotatably mounted on the stationary shaft 59.

Each member 15 has a longitudinal central slot which is adapted to receive a dependingrib 8| located at the underface of a pusher element 82. Since the rib 8| has greater depth than the depth of the slot 89 there will be a space between the bottom 83 of the member 82 and the upper face 84 of the member 15; This space is sufficient to slidably receive the bight portion 85 of a U-shaped bar 16. It will also be noted that the big'ht portion is provided with a slot 86 of restricted width so that the portionsof the bight 85 of the member 16 will be neatly engaged between the bottom 83 of the member 82 and the'upper surface 84 of the member 15. A rod 98' passes through perforations 9| in the member 82 and through an alined perforation 92 in the member 15. A roller 93 is mounted on the inner end of the rod 30 and is adapted to ride in one of the cam tracks 'H' or 12 depending upon whether the pusher element is located to the right or to the left of a plane passing centrally and transversely of the cylinder 10 as shown in Fig. 6.

In view of the fact that a number of the U- shaped bars 16 are located around the cylinder 10, a similar number of pusher elements will be carried around the cylinder and will be alternately reciprocated back and forth by the pair of cam grooves H and 12.

The disks 11 due to the plurality of spaced teeth at their peripheries are in effect sprockets which receive chains 95 and these chains are extended upwardly and trained on sprockets 96 which are located in spaced relation at the upper end of the machine and are secured to a shaft 91 which has bearings in the side walls of the housing.

A motor 98 is hingedly mounted at 99 on the front wall .21 of the housing or the motor if desired may be hingedly mounted on the top 25 of the housing. The position of the motor however is immaterial since either position mentioned above will give satisfactory results. This motor drives a belt I34 which in turn revolves a pulley I3I secured to a shaft I02. A gear I03 is secured to the outer end of the shaft I02 and meshes with a gear Iii-I which is secured to the shaft 91. Since the shaft 9'! revolves the sprockets 96, the chains 95 will be driven as will be the sprockets TI.

The gears I03 and IE4 are housed within a casing Hi5 secured to a side wall of the machine.

Referring more particularly to Figs, 2 and 4 it will be seen that a plurality of spaced rods H are connected to the chains 95 and these rods are adapted to be carried downwardly at the front portion of the machine as indicated by the arrow in Fig. 2. If the cans are being normally fed these rods will move downwardly and neatly engage between a pair of the cams and contact substantially a mid portion of the side wall of the cans when they are fed into the machine from the single track 52. ity of delivery may be disturbed in some manner so that a can may fall directly below the conveyor rod H3 whence the rod will press directly downwardly on the can along points which are in a plane passing vertically and ,diametrically of the longitudinal axis of the can. In that event the can will be forced downwardly on the flexibly supported section 65 of the incoming track and since the member 55 is resiliently supported by the springs '1, the member 55 will give sufficiently until the conveyor rod slips over the top of the can whence the next oncoming conveyor rod will be engaged between a pair of cans so that the cans will be moved forwardly and up wardly to the discharge point at the table 39.

The inner pairs of

tracks

45 and 45 are secured to transverse bars H2 and I53. These bars have their ends secured to the

side walls

23 and 24 at points where the

respective bars

33 and 34 are secured to said side walls. The tracks are riveted to the supporting bars H2 and H3 as shown at I'M. A pair of guards H5 which are 'u-shaped in cross section embrace the chains at points adjacent the outlet of the cans at the rear of the machine. These guards are supported in any approved manner by the side walls of l the housing.

It will be noted that the upper ends of one of the flanges as indicated at I It in Fig, 2 are curved outwardly toward the discharge openings at the rear of the machine in order to aid in guiding the cans to the conveyors 44 and 44a A curved lip II! which depends from the upper edge of the discharge openings 38 cooperates with the curved portions IIB of the

tracks

45 and 46 for aiding in discharging the cans onto the conveyors 44 and 44a.

As shown more particularly in Figs. 1, '7 and 8, the discharge conveyors 44 and 440. are provided at points with a device for stopping the motor 98 when the cans are held on the conveyors due to some disturbance in the uniform delivery of the cans to the packing machine. When this happens the weight of a can or cans will be sufficient to depress a lever which will open the switch to the motor.

However the uniform- The specific embodiment of such a device includes a pair of rlevers I20 and I2I which are hingedly connected at I 22 to the respective tracks 44 or 44a. In view of the fact that each device is a counterpart of the other only one of the devices Will be described and the same reference numerals will be employed in each case. It will be noted that the angle irons I23 which form the bottoms and the side walls of the tracks 44 and 44a are cutaway so that the levers I20 and I2I will span the space between the side flanges I24 of the angle irons I23 whereby the depressible levers may be freely moved between the side flanges.

A red I25 extends transversely of the tracks 44 and 44a adjacent the forward end of each lever I20 and I2! and in spaced relation with the free ends of said levers. The rod is connected by depending bolts I26 which are rigidly secured at their upper ends to the levers I20 and I2! and at their lower ends to the rod.

An angularly shaped arm I21 has its lower portion I 28 secured to the rod I25 and then has a vertical portion I25 extending through an opening I39 in a longitudinally disposed spacing bar I3I which is located between the pairs of tracks 44 and 44a. and secured thereto in any approved manner. A pin I32 is secured to the free end of a horizontal portion I33 of the member I21 and this pin is adapted to be moved through an opening I34 formed in the bar I3I to engage a spring contact member I35 carried by a casing I36 secured to the underface of the bar I3I. A stationary contact member I36 is located above the member I35 and is normally in engagement with the member I35 for closing the circuit to the motor 98. A coil spring I31 located between the bar HI and the horizontal member I33 of the arm I21 tends to maintain the member H1 in its uppermost position and also tends to maintain the levers I20 and I2I in a horizontal plane which passes through the bottom flanges of the angle irons I23.

The operation of my device is as follows: Th cans are fed through the single track 52 into the front end of the machine and the cans as shown at 0 roll downwardly on the inclined flexible member towards the rigid curved membe 65. The motor 93 at this time is in operation for driving the sprockets 96 on the shaft 91 and the chains 95 are likewise driven so that the sprocket wheels TI are likewise revolved. In view of this the transverse conveyor bars i I3 are moved downwardly in the direction indicated by the arrow in Fig. 2 and these bars will normally move between a pair of cans so that the oncoming bar will always engage the rear portion of the can and move it along the single track leading into the machine and below the revolving U-shaped bars 15.

Since the U-shaped bars are revolved around the stationary cylinder I0 and since the rollers 53 on the lower ends of the bolts are moving through the cam grooves II or I2 as the case may be, the members 82 will be shifted back and forth as they revolve around the cylinder 10 by the U-shaped bars I6.

It will be seen that the cam grooves II and I2 are so constructed that each one of the pusher members 82 in alternation at each side of a vertical plane passing transversely through the center of the cylinder I0 will engage the cans in the track and continuously shift these cans gradually towards the side walls 63 of the member 60 which extends from the rear of the machine at the bottom in a curved manner and then downwardly and beneath the cylinder 10. Each pusher element 82 when it engages an end of the cam moves the can completely to one side of the transverse plane so that the can will be in a position to be moved by the conveyor bars H into one of the pairs of

tracks

45 and 46, and since these conveyor bars move around the cylinder I0 and then upwardly at the rear of the machine the cans shown in Fig. 2 are carried upwardly until they reach the platform 39 whence they will roll out onto one of the respectivetracks 44 or 44a.

The continued discharge of cans in double rows will be maintained until for some reason the cans are held against movement on the tracks 44 and 44a whence the weight of a can will depress the levers I20 and I2I.

' As has been stated, the stoppage of the travel of the cans along the tracks 44 and 44a will cause the free ends of the levers to be depressed whereby the member I2! will be carried downwardly causing the pin I32 to engage the con tact I35 and move it away'from the contact I36 and since. these contacts are included in the circuit (not shown) which controls the opera- 'in their normal rate of travel into the machine,

a lever will be depressed causing the breaking of a circuit to the motor 98. Such mechanism, however, has not been shown because the same is similar in construction to that illustrated in Figs. 'land 8, as described above.

As has been previously described, when the cans are passing through the entrance to the I machine and over the flexible member 65 in an orderly manner, the conveyor bars III) should move down between a pair of cans as shown in Fig. 2 so that the bars will engage the longitudinal side Wall of the can and carry them through the single track at the entrance and thence into the double tracks, after which they are discharged. However, a delayed action on the part of some of the cans may cause one of the cans to fall directly beneath a conveyor bar III! as shown at C in Fig. 2. When this occurs the bar will press downwardly on the can and since the ends of this track 65 are supported by the spring 61. at the inner end, said flexible member will be moved to the dotted line position as indicated at 65.

Since the bar IIO continues its movement a can may be forced forwardly or rearwardly, depending upon the exactpoint of contact between the can and the conveyor bar. However, the downward bend or flexing of the track 65 will take care of any strain imposed on the can or on the machine and the can will be freed from the pressure and will move in its normal manner thereafter through the tracks.

Each bolt 90 has a threaded portion I25 which after passing through the vertical passage 9| in the pusher element 82 is screwed into the threaded passage 92 in the block or base member I5. The unthreaded portion I26 of the bolt acts as an axle for the roller 93. A head I21 and a nut I28 hold the bolt and the roller in place,
