38 Claims.

This invention relates to an apparatus for measuring and filling granular material into positioned containers moving in successive processional arrangement past filling stations and is particularly adapted to the handling of such material as peas, beans, cereals of various kinds, or any material of a globular shape or that is of a pulverulentnature that will flow easily through orifices and which may be handled en masse and measured quantities successively removed therefr'omby constantly operating mechanism.

While the invention is adapted to the handling of a varied assortment of materials, in order to make this description and the operation of the machine embodying the invention that is illustrated by the drawings accompanying this application, easily understood, the description will be substantially confined to the handling of such materials as green peas as handled in canning factories in the canning of food products, it being understood that the handling of any other granular product will be in substantially the same way and with substantially the same general results.

In all previous apparatus for handling and measuring such granular materials as green peas and delivering measured quantities to a succession of rapidly moving containers, such as the commercial open end tin can, the mechanism has included some kind of measuring chamber or device for segregating a given quantity of material from a mass and then depositing this measured charge of material into a container, always with a more or less consequent damage to the material through crushing and mutilation where the 183.18;-

n a tempt has been made to overcome this damaging of the material by'the interpositioning of clearance spaces and various arrangements of the edges of the measuring chambers and attending surfaces so that the actual cut off of the measured charge is effected without the metal edges coming together to crush some of the material, and this has been done with a measure of success, but even so, the successive handling of the mass of material and the segregated charges in the manner necessary to isolate measured quantities to satisfy the demands of the packing methods in commercial canning plants has still resulted in some damage tothe product'from excessive manipulation and handling. Measuring chambers,

plungers moving therein and the attendant mechanism for operating them adds additional cost to the apparatus and'extra expense for operation and maintenance and the consequent agitation of the material when handled in this manner results in a more or less degrading of the product in spite of the efforts made to prevent just such conditions.

Applicants device is designed to deliver meas- 5 ured quantities of granular material to a positioned container without the interpositioning of measuring chambers and their attending mechanism and to deliver a more accurately measured charge than has heretofore been possible or prac; ticable in commercial practice.

Generally considered applicants device comprises a rotating hopper set on an incline of substantially degrees, although this angle is not a fixed necessity since other angles of inclination 15 will operate efiiciently, applicant has found that this angle of inclination will handle such material as green peas in a very efficient and satisfactory manner. This inclined hopper is the depository for a mass of granular material. t is given con- 20 stant rotation by means of suitable mechanism and carries means for receiving open end cans in succession from a suitable source of supply and carry them through a circuitous path into and out of contact with a mass of granular material 25 deposited in the hopper, from which mass each can receives a charge of material as it passes. At this time the measure of material is not necessarily extremely accurate as it passes into the can, but as the can advances through its path, moving with the hopper, it is brought into a position where its axis is substantially horizontal. Before it reaches this position, however, the open end of the can, substantially full of peas, passes behind an adjustable shield which prevents the peas from falling out of the can into the mass from which they were taken. This shield will, according to its adjustment, prevent the peas from rolling out of the can when in the horizontal position, except to just the extent desired to leave in the can the required measured quantity, andby thus spilling the excess from the cans after filling in the manner to be more fully de- V scribed, applicant has succeeded in filling cans under commercial practice wherein the fill showed 45 a variation of less than one tenth of an ounce in successive cans, which is a more accurate result than has heretofore been obtained as far as applicant is aware.

In the design of an apparatus to embody the invention, simplicity of construction and operation were of dominant importance. An endless conveyor for delivering open end empty cans to the filling mechanism also acts as the conveyor 7 for carrying the filled cans from the machine. 5

There is really only two moving elements, that is operative elements in the machine. The rotating hopper and the endless conveyor, with the necessary connections in the way of gearing etc., to produce constant and synchronized operation. A curved chute delivers the open end cans by gravity to the conveyor. In the rotating hopper is positioned a division wall which extends substantially radially to one side of the hopper, this wall together with the hopper wall form the depository for the mass of peas which due to the inclination of the hopper, pyramid in the intersection of this fixed wall and the wall of the hopper adjacent thereto as will be more fully pointed out in the ensuing description.

Diagrammatic means are shown for stopping the operation of the machine in case a can is missed which will prevent loss and spilling of peas in case a filling opening is not covered by a can.

This stop mechanism as shown is electrical, but it is quite obvious that mechanical means can -be applied very easily if preferred, the object being to show a means rather than a distinct device.

It is a principal object of the invention to provide an apparatus for handling and measuring granular or like material wherein a moving container is charged with a measured quantity of material and the container itself acts as the measuring medium.

It is also an object of the invention to provide an apparatus for the purpose specified wherein open end containers are delivered to a rotating element which conveys them in succession into contact with a mass of granular material from which mass each container receives a measured charge of material without the interposition of any measuring device.

It is a further object of the invention to provide an apparatus for the purpose wherein a mass of granular material is pyramided in a rotating hopper so that it follows the rotation in only a limited extent, and has direct connection with open end containers as they are moved past the mass whereby each container is filled with material from the mass.

It is also an object of the invention to provide an apparatus for filling open end containers with 'material wherein the containers are moved from a vertical position to substantially a horizontal position and back to a vertical position during their passage through the machine and during said passage to receive a fill of material and to have the excess spilled therefrom to leave an accurately measured charge in each container.

It is a further object of the invention to provide a machine of the class described wherein a material container element also acts as a container moving element for moving single containers past a mass of material in said container element whereby said containers will receive a charge of material therefrom.

It is also an object of the invention to provide an apparatus for filling measured quantities of a granular material into open end containers wherein the containers are over filled and by a continued movement through the same path and by the same mechanism a portion of said material is controllably spilled therefrom to leave an accurately measured quantity in each container. 7

It is a further object of the invention to provide an apparatus for the purpose wherein a rotating hopper in conjunction with a fixed memher will act to pyramid a mass of granular material within a restricted zone in the hopper space whereby the said hopper may convey single containers past said mass and have deposited therein a charge of material.

It is also an object of the invention to provide an apparatus for the purpose wherein a rotating hopper in conjunction with a fixed member and. an adjustable member both within the hopper space will segregate a mass of material within a restricted zone within said hopper whereby a container moved past said fixed and adjustable members will receive an accurately measured charge of material.

t is also an object of the invention to provide an apparatus for the purpose wherein a rotating hopper adapted to hold a mass of material is positioned at an inclination and has a series of filling ports for admitting material to open end containers in contact therewith and is adapted to engage and move containers through an inclined circuitous path whereby each container will receive a charge of material from the mass within said hopper.

It is also an object of the invention to provide an apparatus for the purpose wherein a rotating circular hopper is set on an inclined axis with a circular inclined pathway adjacent and under said hopper to form a bottom support for containes, with means on said hopper for engaging and moving containers through said inclined pathway and with means in said hopper for segregating a mass of material at one side thereof whereby as containers are moved through said pathway they successively receive a charge of material therefrom.

It is also an object of the invention to provide means for stopping the machine in case the feed of cans or containers is interrupted to thereby preventrthe spilling and loss of material if a filling opening passed the mass of material without being covered by a container.

It is also an object of the invention to provide an apparatus for filling containers with a loose material wherein the containers are moved through an inclined circuitous path and are at the same time axially rotated to cause a rolling: of the material charged therein, the containers: moving from a vertical to a horizontal and back:

7 to a vertical position during said transit.

With such objects in view as well as other advantages inherent in the invention, the novel structural peculiarities, novel organization of elements, and the separate and collective operations involved in carrying out the recited objects of the invention, which will be made the subject matter of claims hereto appended, I wish it understood that the several necessary elements and combinations constituting the same may be varied in their proportions, general arrangement and operative relation without departing from the scope and nature of the invention. In carrying out the invention in a concrete form or machine, further objects, advantages and improvements have been evolved than have been recited, and in order to make the invention more clearly understood there are shown in the accompanying drawings means and mechanism embodying the preferred structural arrangement and disposition of the different parts and combinations in which I have only illustrated one way of embodying the invention. The described devices are simply embodiments of the invention which other structures might also employ and some of the parts or combinations may be used without the others in different types of such machines'without departure from the purview of my invention and I therefore regard myself as entitled to such variations from the shown and described devices as fall within the scope and meaning of the claims.

Referring now to the accompanying drawings which are more or less diagrammatic in character; are not necessarily drawn to scale and in which some parts may be more or less exaggerated in size and proportion to better show the structure and operation, a better and clearer understanding of the structureand operation will be understood.

Fig. 1 is a vertical sectional elevation of an apparatus embodying the invention and has been taken on substantially the line ll of Fig. 3. This view shows clearly the manner of inclining the rotating hopper; its positioning directly over the endless conveyor which serves to move the containers to and from the hopper element and the manner of feeding the empty containers to the endless conveyor.

Fig. 2 is a sectional elevation taken on the line 2-2 of Fig. 1 but with the inclined hopper set up into a vertical plane to avoid the confusion of a part perspective view. It was thought this manner of showing the device in this view would be preferable since the sections are all looked at from the same plane.

Fig. 3 is a sectional plan of the machine taken on approximately the line 33 of Fig. 1. This view clearly shows the endless conveyor; the deflector member that diverts the containers into the circular trackway and back onto the conveyor as well as the stopping mechanism whichoperates when a can is missed.

Fig. 4 is a plan of the hopper looking in direction of the arrows 4 of Fig. 1. This view clearly shows the division Wall in the hopper that acts to segregate the mass of material at one side of the hopper and also shows the spill gauge that controls the spill of the excess material to give an accurate fill to each container.

Fig. 5 is more or less of a diagrammatic view showing a portion of the rotary hopper; the inclined surfaces at the entry and exit of the circular path for the containers; the deflector for controlling the direction of movement of the containers and the conveyor.

The numeral l represents generally the frame work of the machine. 2 represents the endless conveyor, and 3 the inclined hopper and 4 the curved chute for directing the cans to the upper surface of the conveyor 2. At one side of the frame I will be seen the main drive shaft 5 on which is mounted the drive pulley 6 controlled by the clutch 1, the clutch members being operated by the combined manually and electrically controlled lever 8. The endless conveyor 2 is mounted on suitable sprockets 9 and If] in turn carried by the shafts I I and I2 and is driven by the chain l3.

The hopper 3 is mounted to rotate on the inclined shaft M and carries around its upper periphery the ring gear which is driven by the gears 16 and H through the shaft 18, bevel gears l9 and mitre gears 20 from the main shaft 5.

Fig. 4 shows a plan arrangement of the division wall in the hopper as at 2| where it will be seen that this wall has a radial section 22 which contacts with the inner wall of the rotating hopper. It is at the intersection of this division wall and the inner wall of the hopper that the granular material will tend to pyramid as the circular lines the manner in which the material will tend to climb up the inner wall of the hopper and then fall back on the mass. There can be no crushing or multilation of material here 5 because the hopper wall is always moving away from the wall 22.

This Fig. 4 also very clearly shows the spill gauge located within the hopper space and lying along the upper wall of the hopper as it rotates, the portion 23 acting to partially cover the filling openings in the hopper as it revolves and by its adjustment circumferentially controls the amount of material spilled from each container as it passes. The desired adjustment is held by the set screw 24, this will be further explained under operation.

A stop mechanism is shown in somewhat of a diagrammatic manner on Fig. 3. Arranged to contact with the passing cans as they start 20 up their incline is a detector lever 25 pivoted at 25 and carrying an electrical contact member 27 and held in the position shown by contact with the passing cans against the tension of the spring 28. A fixed contact 29 is located in oper- 25 ative relation with the contact 27 so that if a can is missing from a filling opening the spring 28 will tend to close the electrical circuit by bringing the contacts 2'! and 29 together when the solenoid magnet 39 will be energized, the 30 plunger 3i be pulled laterally and through its connection with the clutch lever 8 release the clutch and stop the machine and at the same time flash a signal through a colored light 32, or in place of a light an ordinary buzzer may be placed in the circuit, when an operator will place a can in the empty space to replace the lever 25 in its inoperative position and the machine started. Other features of structure will be referred to in the operative description to follow.

Operation In this operative description I will, for the purpose of simplicity refer to the material being handled as the ordinary green peas of commerce.

I prefer to deal with this material because the highest grade of product is very delicate and. very easily crushed and mutilated in the ordinary automatic machinery for filling the product into the commercial cans, and when so crushed and mutilated is quickly reduced to a lower grade material resulting ina financial loss to the packer and offering to the consuming public an inferior grade of food.

In the canning of green peas they require more or less of handling in several different kinds of apparatus beforethey reach the filling machine. They must firstbe separated from the pods in a pea threshing machine which beats them about more or less and has a tendency to cause some mutilation. They must then be washed, graded for size, separated from refuse materials and finally blanched or at least subjected to the action of steam or hot water to give them a preliminary cook before being placed in the cans for final disposition. When the peas reach the ordinary filling machine they are more or less soft and tender and much more easily bruised than at any other time in the process before going into the cans, and this is the time 7 that the most careful handling and eflicient apparatus will produce the highest grade product that Will bring the most money to the packer. My improved filling machine will now take the tender peas and fill them into cans with prac-..75

tically no bruising or mutilation and will give to the packer the highest grade product he has ever had as far as filling practices go.

In Fig. 1, I have shown a simple source of supply in the shape of a conveyor belt which brings the previously treated peas to a chute which deposits them into the hopper 3 as shown. When the -machine is operating continuously there is a uniform decrease of the quantity of material in the hopper and the supply should provide sufficient additional material to maintain a substantially uniform mass in the hopper so that the filling operation will be carried on under uniform conditions. The supply of open end cans will come down the gravity chute 33 in uniform succession and will pass onto the conveyor belt 2 to be in turn presented to the feeding elements or spacing members 34 carried by the hopper 3 and by means of the deflecting member 35 resting directly over the conveyor 2 at the point of passing into the zone of the members 34 will be deflected away from the conveyor 2 and will begin their passage through the circuitous path 36 which is provided by the member 31 located adjacent the bottom of the hopper 3. The fixed path provided by the member 31 is substantially circular and in the same inclined plane throughout its extent except at the point where the cans enter.

By referring now to Fig. 5 it Will be seen that the entrance and exit of the member 37 is somewhat tapered where it adjoins the conveyor 2 .so that as the cans are swept off the conveyor 2 by means of the can feeders and spacers 34 they will slide up the incline 38 which will gradually raise them up into the tapered mouth of the orifice 39 which will roughly center them with the orifice. The cans are now held in this position by sliding on the bottom of the trackway 35 .and the spacers and feeders 34. Likewise as the cans return to the conveyor 2 to be carried away from the filling hopper 3 they slide down the incline 40 out of alignment with the orifice 39 and by means of the deflector are swept onto the conveyor 2 to be carried away.

In operating machines of this type it is supposed that the cans will always feed in uniform succession without miss and that a can will always be present to cover a filling orifice, but

fiow of cans and a filling orifice will pass the conveyor 2 .without getting a can, in which case, if the machine is permitted to continue its operation this open orifice, when it reached the mass of peas in the hopper would permit them to run out, and if no means were provided to catch them they would go on the floor and be lost.

In order to obviate such a condition I have shown diagrammatically in Fig. 3 one Way of preventing such a condition to develop. Along the trackway 36, just as the cans enter from the conveyor 2 there is a pivoted lever 25 which is normally held in the position shown by the presence \of cans in proper spaced succession. This lever, or the portion in contact with the cans is of such a length that a can must be in the position A, to contact with the lever 25 before the can at position 13 passes out of contact, in which case the lever will be continuously held in the position shown, if, however, a can is missing from the position A and the can B passes out of contact with the lever the spring 28 will immediately pull the lever into the space that. should be oc- 30 thus pulling the clutch lever 8 and stopping the machine, which cannot be again started until the lever 25 is pulled out toits normal position by inserting a can in the. empty space. The signal 32 indicating that the machine has stopped may 5 be a colored light or a buzzer, anything that will attract the attention of an operator to come and. right conditions.

Refer to Fig. 4 now and we will see how the cans are filled direct from the hopper with uniform 10 charges of material without the interposition of any kind of measuring device other than the can itself.

The orifice at position C is where the orifice and empty can come into alignment as shown in elevation in Fig. 5. In the space of the hopper defined by the circular wall of the member 2|, the radial wall 22 and the outer Wall of the hopper 3 is always empty so that there are no peas to fall through the orifices while changing cans. The '20 peas are fed into the space indicated by the circular dotted lines above the radial wall 22. This wall being fixed and the wall of the hopper always moving upward in the direction of the arrow tends to roll the mass of peas in contact with 25 the hopper wall upward away from the wall 22, but the quantity assembled at one time is sufficient to form a pyramid at this point and since the movement of the hopper wall is sharply inclined the peas will fall back onto the mass as they are carried up from the bottom of the mass. This slight easy agitation is sufficient to prevent bridging of the mass and thus effecting a uniform fill. As the cans begin their travel along the inclined path 36 and the orifice D with a can underneath just passes under the division wall 22 the edge of the orifice will pass under and in direct contact with the mass of peas resting against the wall 22 and they Will immediately roll into the can and will so 40 continue as the can and orifice move upward under the mass until the can is completely filled. As the can and orifice continue their movement through the upwardly inclined pathway they will gradually pass from under the mass and the charge in the can will be separated from the mass without any other out off than the simple moving of the filled can from the mass. There can be no crushing here because there is nothing present but the peas themselves.

As the filled can passes from under the mass its axis is being gradually converted from a vertical position at the point C to a horizontal position at the top of the inclined path as at F I Fig. 1. If some means were not provided at these upper positions to keep the peas in the cans the most of them would roll out and fall back onto the mass below. To prevent this and to regulate the amount of peas retained in each can there is provided a spill gauge in the member 23. With the cans completely full when they rise up the incline from the filling position the peas will begin to roll out as soon as the tilting of the cans are sufiicient to begin the spill. In no instance is it desirable to have the cans completely full of peas so that a certain amount must be spilled. The beginning of the spill may be unrestricted but as soon as a certain amount have rolled out the spill gauge 23 should be adjusted circumferentially to begin .to partially cover the orifice "O and restrict further spilling. If the gauge member 23 is placed'in a position to the left of that shown in Fig. 4 so the orifices are covered sooner the cans will retain a larger quantity of peas, while if a less quantity is desired in each can the 7 5 normal spill occasioned by the increased inclination toward the horizontal position of the cans is permitted to continue for a longer period before the spill gauge acts to restrict the spill. The adjustment to produce this eifect is setting the spill gauge to the right of the position of Fig. 4. It is to be understood that this description of the adjustment of the spill gauge is only illustrative and is not intended to represent accurate adjustments, neither is the position of this gauge in Fig. 4 necessarily correct for any condition of operation. It may be necessary to have the gauge portion shorter or longer than shown and it may be adjusted on either side of that shown for normal operation. After the cans pass the top horizontal position they gradually begin to tiltback until they reach the position of the can at the right of Fig. 5 when they have almost reached the vertical position, and do reach this position as they again rest on the conveyor 2 to be carried away from the machine.

By reference to Fig. 3 it will be seen that the cans leave and return to the conveyor 2 at substantially the same point, the two arrows here show the direction the cans take. The movement of the conveyor 2 should be slightly faster than the movement of the hopper so that the line of cans approaching the trackway 36 will push one another against the outer edges of the spacing members 34 so that no time will be lost in getting each can into the space between two members 34 as the cans move from the conveyor into the pathway 36 and start their inclined travel. The frictional effect of the conveyor on the bottoms of the cans when they first contact with the edges of the spacing members 3 1 will help to quickly push them into the spaces as soon as they are permitted to enter by the rotation of the hopper and the spacing elements.

The member 2| is shown as positioned and held in adjustment by a set screw 4! Fig. 2. Fig. 4 shows that this member is mounted on the shaft [4 so that it may swing circumferentially to any adjustment desired, by which means the division Wall 22 may be placed lower or higher than that shown.

It is believed that a new method has been evolved in the art of filling granular material into moving containers by the development of this invention and that this method comprises the steps of passing empty cans under a mass of granular material whereby the material will flow directly into the cans which act as their own measuring devices, cutting oil the filled charges in the cans from the mass by simply moving them out of-contact with the mass then standardizing the fill by spilling a controlled amount from each can as the cans pass through a continuously changing axial position.
