20 Claims. (Cl. 198-30) The present relates to conveying and arranging mechanism, and pertains more particularly to apparatus for the rearranging of containers or cans from an indiscriminate mass thereof into a single file.

In the packing of liquid and solid foods or other products into bottles, jars or cans, it is customary to receive the containers in shipping cases, such as cartons or boxes, with the open ends of the containers all directed toward one side of the case. Glass containers, such as bottles or jars, being comparatively heavy, may be dumped out of the cases easily by first removing the side of the case covering the bottoms of the containers, and then inverting the case onto a receiving or sorting table. The lighter weight metal containers or cans, however, tend to hang up in the cases when they are so inverted, with the result that some of the cans may tip over when the case in which they are packed is withdrawn. Since the machines for filling or otherwise processing the containers customarily are designed to receive the containers in single file, it usually is necessary to rearrange the containers into such single file for feeding them to the processing machines.

In the past, difiiculty has been experienced in devising a machine which would perform this rearranging operation rapidly, without damaging or tipping over containers, and without likelihood of jamming.

The present invention contemplates the provision of mechanism for rapidly and accurately rearranging a massed group of containers into a single file thereof. The invention also has as an object, the provision of mechanism for receiving the contents of a case of containers dumped promiscuously in upright position thereon, and for rapidly rearranging the containers into an advancing single file thereof, While at the same time removing excess containers from a zone wherein jamming is apt to occur.

A still further object of the invention is to withdraw in upright condition from a case in which they are packed, a plurality of empty cans of magnetically permeable material when said case with a side removed therefrom is inverted onto a receiving conveyor forming part of a mechanism for rearranging the containers into a single file thereof.

These and other objects and advantages of the invention will be apparent from the following description and the accompanying drawings, wherein:

Fig. 1 is a plan view of a mechanism embodying the invention, portions thereof being broken away.

Fig. 2 is a vertical longitudinal sectional view taken along line 22 of Fig. 1, portions thereof being broken away. i

Fig. 3 is an enlarged, fragmentary, sectional view taken along line 3--3 of Fig. 1.

Fig. 4 is an enlarged, fragmentary, perspective view of the discharge end of the apparatus shown in Figs. 1 and 2.

Fig. 5 is an enlarged, fragmentary, plan view of the portion of the apparatus shown in Fig. 4.

In general, the illustrated mechanism comprises a frame A of conventional, structural steel type. A belt-type receiving conveyor B (Figs. 1 and 2), of a width to re ceive cases X of the containers to be arranged, is mounted on the frame A. While machines embodying the present invention are capable of handling various types of containers, including glass jars and bottles, the accompanying illustrations show the machine as being used with metal containers. In the present description and claims, therefore, the word cans is intended to include all such type of containers.

The cans deposited on the receiving conveyor B are carried toward the left, as shown in Figs. 1 and 2, and are there transferred onto an arranging area X. From the arranging area X the cans are discharged in single file through a throat D into a usual can carrying chute E.

The receiving conveyor B comprises a belt 10 of a width to receive a case C of cans deposited thereon. A pair of side retaining walls 11 and 12 are mounted along opposite sides of the belt 10. The belt 10 is trained over rollers 13 and 14, and the roller 13 has driven connection, by a drive belt 15, with a pulley 17 mounted on the shaft 18 of a motor driven speed reducer 19.

A plurality of magnets 20, which may be either permanent or electro-magnets, are mounted closely to underlie the receiving belt 10. Then, when a case C of cans 21 is inverted to deposit the cans, bottoms down, on the receiving conveyor B with the magnets 20 energized, the magnetic attraction of the magnets upon the sheet steel of the cans will draw the cans tightly against the receiving belt 10. With the cans thus held, inverted case C may be raised free of the cans without danger of having any of the cans hang up in the case.

The side walls 11 and 12 converge, at 11a and 12a respectively, toward the discharge end of the receiving conveyor B to direct the case C of cans 21 dumped thereon onto three forwardly driven conveyor belts 22, 23 and 24. All three of the belts 22, 23 and 24 have the ends thereof toward the receiving belt 10 trained around similar pulleys 27, 28 and 29, respectively. These pulleys are mounted to rotate freely on a shaft 30 supported in brackets 31 secured to the main frame A.

A transfer shelf 32, over which the cans 21 are adapted to slide freely, is provided between the receiving conveyor B and the forwardly driven, can arranging belts 22, 23 and 24. The other ends of the belts 22, 23 and 24 are trained around three separate and independently driven pulleys 33, 34 and 35 (Figs. 1 and 2) mounted respectively on shafts 37, 38 and 39. The three pulley support shafts 37, 38 and 39 are journaled in conventional bearing supports, not shown, mounted on the frame A. The shafts 37, 38 and 39 are driven (Figs. 1 and 2) at different speeds by separate belts 37a, 38a and 39a, respectively, from a countershaft 46. The countershaft 46 in turn is driven by a usual drive belt 46a from the speed reducer shaft 18.

The inner belt 22 is driven to travel faster than the intermediate belt 23, which in turn is driven to travel faster than the outer belt 24. All three of the belts 22, 23 and 24 travel faster than the receiving belt 10, so as to remove the containers rapidly and to space them apart as they are pushed slidably across the transfer shelf 32. Two oppositely moving return belts 40 and 41 are mounted on the opposite side of the belt 22 from the belts 23 and 24. These two latter belts 40 and 41 have their ends adjacent the receiving belt 10 mounted on pulleys 42, 43 journaled to rotate freely on the same shaft 30 as the pulleys 27, 28 and 29.

The left hand ends of the return belts 40 and 41 are trained over drive pulleys 44 and 45, which are driven by conventional drive means, not shown, so as to drive the return belts 40 and 41 in the opposite direction from the 3 three first mentioned belts 22, 23 and 24. Preferably the outer return belt 41 is driven at a slower speed than the inner return belt 40.

All of the conveyor belts of the illustrated mechanism have their upper conveying surfaces disposed substantially in the same plane, so as to facilitate transfer of the containers from one belt to the other.

A side wall 47, forming a continuation of the side retaining wall 11 for the receiving conveyor B, prevents lateral displacement of the containers beyond the outermost forwardly driven belt 24.

An oscillating wall portion 48 is hingedly connected to the left hand end of the side wall 47, as shown in Figs. 1, 2, 4 and 5, and a resiliently flexible deflector plate 50 is hingedly connected to the side wall 47 at 51. The deflector plate 50 has slidable connection with the oscillating wall member 48 at 52. The left hand end portion 53 .of the oscillating wall member 48 is bent outwardly at 54. The bend 54 in the oscillating plate 48, which is the farthest projection of this oscillating plate, is in alignment, in one of its positions, with a side edge of the center high speed belt 22.

For oscillating the wall member 48, a downwardly extending post 55 (Fig, 3) is connected to the end of the outwardly bent portion 53 of the oscillating wall member 48, and a fitting 57, having a cam follower roller 58 mounted for free rotation therein, is mounted on the lower end of the post 55. The cam follower roller 58 rides against the tilted face 59 of a rotary cam plate 60 mounted on the shaft 37. A coil spring 56 (Figs. 1, 3, 4 and is connected in tension from the free end of the oscillating wall member 55 to a post 56a secured to the frame A to retain the roller 58 in contact with the cam plate 60.

A fixed guide wall 61 is mounted beyond the bend 54 in the oscillating wall member 48 to form one side of the throat -D which guides the cans 21 into the chute E, to be described later herein.

A second fixed guide wall 62 is mounted in laterally spaced relation to the first throat side wall 61 to define the other sideof the throat D through which the cans pass to the chute E. A rotary deflector post 63 is mounted at the upstream end of the wall 62 at the opposite side of the central high speed belt 22 from the bend 54 in the oscillating wall portion 48. A plurality of frictional bumper rings 64, which may be of resilient rubber, are

mounted at axially spaced intervals to encircle the portion of the rotary deflector post 63 above the level of the conveyor belts.

A pair of arcuately curved bars 65, 65 extend transversely across the two return belts 4t) and 41. The inner ends of the bars 65, 65 are connected to the end of the throat defining wall 62 adjacent the rotary deflector post 63, while their outer ends are connected to a side wall 67 which extends along the outer side of the outermost return belt 41. An angularlyinwardly directed wall portion 68 (Fig. 2), which is a continuation of the side wall .67 and of the wall portion 12a is mounted to extend obliquely across the return belts 40 and 41 to deflect inwardly onto the central, high speed belt 22 any cans which may be carried back by the return belts.

The discharge chute E is of a conventional type, having top and bottom guide rods 70 and 71, respectively (Figs. 4 and 5) adapted to engage opposite ends of the cans entering the chute E in upright position. A pair of side rods 72, 72 and 73, 73 are provided on opposite sides of the chute E to engage the sides of the cans entering the chute=E to guide the cans along through the chute. The chute illustrated is formed with a quarter twist at 74 therein to tilt the cans from upright to axially horizontal position. The side retaining rods 72, 72 which are on the bottom of the chute after the completion of the quarter twist .74 therein, are spread apart for a short distance as at 75 (Fig. 5) to allow any cans which may enter the chute E in a horizontal lengthwiseposition to drop out between the spreadapart portions of the rods.

The operation of the mechanism will be described briefly. Assuming that the mechanism is in operation, with the upper surface of the receiving belt 10 moving toward the left as shown in Figs. 1 and 2, the magnets 20, if of the electro-magnetic type, may be energized by closing a switch 76 in a conventional electrical circuit comprising conductors 77, 78 and 79, the switch 76 and a battery 80, or other suitable source of electrical energy. The switch 76 may be closed either continuously during the operation of the machine, or momentarily as each case C of cans 21, with a side thereof removed to expose the bottom of the cans, is dumped onto the receiving belt 10.

The three forwardly driven belts 22, 23 and 24 also will be driven at successively increased speeds, from the outermost, relatively slowly moving belt 24, to the central, relatively high speed belt 22. The two return belts 40 and 41 also will be driven in the opposite direction from the belts 22, 23 and 24, the outer return belt 41 preferably being driven at a slightly slower speed than the inner return belt 40. The deflector post 63 will be rotatively driven in the direction of the curved arrows adjacent thereto in Figs. 1, 4 and 5, and the oscillating wall 48 will be moved through successive cycles of oscillation by rotation of the cam plate 60.

As each case of cans 21 is dumped onto the receiving conveyor B the magnets 20 attract the cans to hold them on the receiving belt 10 while the case C is being removed. The receiving belt 10 then carries the cans 21 toward the left, as shown in Figs. 1 and 2, the rearward cans pushing those ahead of them across the transfer shelf 32, where the converging wall portions 11a and 12a guide the cans onto one or the other of the forwardly moving belts 22, 23 and 24. Any of the cans which rest partly on any two of the belts will tend to be deflected by impact with cans on the adjacent differentially moving belts onto a single one of the belts.

The cans passing onto the high speed center belt 22 are rapidly transported directly to and through the throat D and into the chute E. The position of the rotating deflector post 63 and the slight lateral curvature of the throat walls 61 and 62 slow down the movement of the cans 21 somewhat before entering the chute E to avoid damaging the cans. The cans which pass onto the two more slowly moving forwardly driven belts 23 and 24 are advanced thereby until the foremost container on each of said belts come into contact with the flexible deflector plate 50 or the oscillating wall portion 48.

The different rates of travel of the three belts 22, 23 and 24 tend to string the cans out into three echeloned columns, so that at least a portion of the cans on the fastest belt 22 will have passed therefrom before those on the adjacent, slower belts are transferred thereto.

The oscillations of the wall portion 48 and of the flexible plate 50 supported thereon, nudge the containers along these obliquely disposed members toward and onto the central belt 22, which thereupon carries them through the 'throatD into the chute E.

In the event that the cans should be fed to the three belts 22, 23 and 24 more rapidly than the belts could dispose of them in the manner described previously herein, the cans might tend to jam up at the entrance to the throat D. In such event, the rotating rubber ringed deflector post 63 will frictionally engage any cans which may be held against it, exerting a transverse deflecting force on such cans in the direction of the small curved arrow in Figs. 1, 4 and 5. This action by the rotating deflectorpost 63 urges any such cans which might have a tendency to jam against it onto the inner return belt 40, Where they are returned toward the receiving end of the machine. There the cans again are deflected, by the obliquely disposed side Wall portion 68 onto the central high speed forwardly driven belt 22.

In the event that a very great excess of cans should be fed into the machine, anyexcess cans tending to jam against the rotating deflecting post 63 would be diverted by the action of the rotating post 63 onto one or both of the return belts 40 and 41, both of which would then return the excess cans to the receiving end of the belt 22 for feeding back onto the belt 22 as described previously herein.

By driving the outer return belt 41 at a slower speed than the inner return belt 40, the cans on the inner return belt will engage the deflecting wall portion 68 and will be returned onto the central high speed belt 22 in advance of the cans on the outer return belt 41, thus tending to string the cans out into differentially moving single file columns, in the same manner as that described for the two outer forwardly moving belts 23 and 24.

By properly adjusting the relative speeds of the various belts of the machine in the manner described herein, the mechanism will tend to clear itself of any tendency to form a jam which might interfere with its operation.

While we have illustrated and described a preferred embodiment of the present invention, it will be understood, however, that various changes and modifications may be made in the details thereof without departing from the spirit and scope of the invention as set forth in the appended claims.
