Petty Patent Specification for the invention entitled 0 "CAN FILLING MACHINE" S

S e The following statement is a full description of this

invention, including the best method of performing it

known to us:

I~it

"I

The present invention relates to a machine adapted

to facilitate filling of cans. More particularly, this machine

is of particular utility in filling cans with meat products.

In the food industry the canning of solid or partic-

ulate portions of meat has been very labour intensive.

Basically the machines used comprise a circular table having

a number pf peripheral pockets provid d therein which extend

downwardly from the table. These pockets are manually filled

by workers who use scoops to scoop up the requisite amount of

solid or particulate meat. Thie aforementioned table is rotat-

able and a mechanism for discharging the meat in the pockets

is positioned on the periphery of the table so that by rotation

thereof those pockets may come into registry with the discharg-

ing mechanism. Such mechanism comprises a plunger having an

axial aperture therein. Initially the plunger is at rest inside

the container against the bottom thereof. As the measured quant-

ity of particulate material is displaced from the pocket through

th'e apertured plunger into the area between the bottom face of

the plunger and upper face of the base of the container the

material imparts an upward moment to the plunger. The weight of

the plunger applies a constant pressure on the particulate mater

ial as it is being introduced to the can. This is clearly to

compact the material and eliminate unwanted air from the can.

Generally machines operating on the above outlined

principle are very large, complex and expensive. Further, 0nere

one is considering such a machine in the context of the food

industry, there must be considered the stringent health regulat-

ions relating to materials from which those machines are to

be fabricated. In this respect stainless steel is the most

common fabricating material used, and where the machines are

7-1

very large such necessarily means a high cost of apparatus.

Another consideration of conventional machines is their inabil-

ity to be easily cleaned at regular intervals. Because of the

number of pockets and mechanisms utilized, it is particularly

time-consuming cleaning such. Further, where reliance is made

on manual labour in the transfer of meat, there is also a risk

of infection occurring no matter how diligent the worker may

be. Thus the presently utilized machines for filling cans with

meat product suffer from being too large, too costly and labour

0 intensive, and it is an object of the present invention to 0

Sr alleviate these disadvantages. 0000

With this object in mind it became readily apparent 0 0 that the bulk of the machine had to be reduced as well as its *0 S labour intensive aspect, as in doing so a significant cost 0 0 0 0 *r 5*0 0 0 saving would be achieved. lhere is therefore provided a machine

Lor filling containers with liquid and/or particulate material

comprising a container receiving station adapted to support

a container, a first member having at least one passageway loc- 0

ated therein which communicates between a first face and a

second face of said member, said member being adapted to be

moved into and out of said container, and a conduit having an 2e

inlet and an outlet, through which liquid and/or particulate 0 material can pass, said outlet being positioned with respect

to said passageway to permit liquid and/or particulate material

emerging from the outlet to enter at least one passageway, so

that in operation an open ended container having a base portion

is located at the container receiving station, the first member

is lowered into the container whereafter liquid and/or partic-

ulate material is caused to be transported through said conduit

and subsequently at Ieast one of the passageways into an area

If 7v defined between the base of the container and the member, the whilst the liquid and/or particulate material filling said area

member retreats from the container until said container is

filled to a predetermined weight at which time introduction of

said liquid and/or particulate material into the conduit is dis-

Scontinued, and said member if necessary removed from the Scontainer. E In a preferred embodiment there are regulating means

re- integrally associated with the machine to interrupt and into the conduit and initiate the flow of particulate material

consequently inte the can.

A machine manufactured according to the invention

successfully eliminates the conventional rotary table and need

for persons to scoop the material by directly feeding from the a a a 9 source of the product to the filling station. The reduction a. 4,. a, in size of machinery resulting from using the concept of the a. a a a invention decreases the costs of fabrication and permits an a. a qo ,a a overall saving. Further, duie to this simplification, cleaning U. WI S Ih a a 0 of the machine can be carried out quickly and efficiently.

In one particular embodiment of the present invention a

the first member is a plunger which is vertically orientated a9 qe 9a a a a for use with an upright container. This plunger is also part- aS a *0 ially encased by the conduit into which liquid and/or partic- o a. eq 0 ulate material can be introduced. The upper end of the plunger

shaft extends from the conduit and is connected to a hydraulic a 9 9. 9 a cylinder which regulates the raising and lowering motion of a A. the plunger face in response to the introduction of material

between it and the bottom of the container. In this way by the

choice of an appropriate predetermined rate of raising the

plunger face, material being introduced is compacted to the

desired extent and avoids the presence of unnecessary air. It

container base to ensure regular compacting occurs, however

the face may be a separate member or members or be an integral

form of the plunger.

Regulation of the flow of the material and introduct-

ion of the can into and from the filling station may be carried

out using a valve arrangement. In a typical possible sequence

initially the machine is in a state where the pump is stopped.

In this respect the flow valve is closed and a can may be pushed

into the machine which activates the valve causing the plunger

face to be lowered into the container. Once the plunger head

is in its initial position neat begins to be pumped through the

conduit and consequently through the

to that shown in Figure 1.

ion with the machines depicted in Figure 1 or Figure 2.

In Figures 1 and 2 there is provided a stand 1 which

is constructed of four stainless steel bars positioned in a

rectangular arrangement. A hydraulic cylinder 2 is attached

of the cylinder 2 there is provided a plunger shaft 4 which is connected to nuzzle 5 through material flow enclosure 3.

Accordingly nuzzle 5 may be lowered or raised by the action

of the hydraulic cylinder. In Figure 2 in particular there *0*0I 00 0: is shown two types of filling nuzzles 5 and 5' which are conven- 0 mOOS iently interchangeable depending upon the shape of the can to

be filled. At the base of stand 1 there is provided a horiz-

ontally orientated ejector ram 6 which once a can has been

filled to the desired level and nuzzle 5 removed therefrom, eig. may move the can out of the filling station and allow replace-

ment thereof with an empty can. *e 0

Referring to Figure 3 there is shown a schematic

0 diagram of a valve arrangement to operate the machine according

to Figures 1 or 2. Basically when valve 5 is closed a can is

pushed into the filling station of the machine, which movement e operates valve 1 and starts the cycle. The filling head travels

to the bottom of the can and operates a switch A and starts *0rr the meat pump, also valve 2 is closed and reverses the filling

head. The meat pump is timed to stop when the correct weight 9* 0* of meat is received. Valves B regulate the pressure on the

meat to obtain a compact fill. Thereafter the can is ejected

by a ram when valves 3 and 4 are activated. The piston on the 0i ejector ram is returned by valve 6. Regulator C is incorporated

and determines the amount of pressure required by the can to

operate valve i.

The machine made in accordance with the present invent-

ion is both compact and not labour intensive. It therefore

reduces costs both relating to space and manpower as well as

the required stoppage time to permit proper cleaning.
