The passageways 6a, 6b are disposed in two substantially parallel rows, and are formed by grooves in opposite side surfaces of a plate 10, the grooves being covered by side plates 11, 12 secured to the plate 10. At approximately one third depth of the magazine 5, slot-like apertures 21 are formed, in order to provide access to the otherwise closed passageways 6a, 6b. The apertures in the plate 11 locate resilient fingers 13 and those in the plate 12 resilient fingers 14. The fingers 13, 14 are mounted on laterally-spaced bars 15 and 16 respectively, and reciprocatory movement of the fingers 13, 14 and bars 15, 16, causes the fingers 13, 14 in turn to arrest the falling columns of material moving down the passageways 6a, 6b. The apparatus may be used in the production of flaked breakfast cereals. <IMAGE>

Description

"Improvements in or relating to Apparatus for Feeding Granular Material to Processing Machines" BACICGROUMD TO THE I0,rVEEION This invention relates to apparatus for feeding granular material to processing machines and has particular application to the production of breakfast cereals from corn, wheat and rice bases, and especially cereals in flake form. The basic materials are first cooked, generally under pressure, then fed in granular form as grits (single grains), or pellets (balls of a number of grains), to the nip of a pair of closely spaced flaking rolls which, by a spreading action, form them into the individual flakes.
As used herein, the collective term "granular material" is intended to embrace grits, pellets, and like forms of granular material.
Similarly, the collective term "grain" is intended to embrace a pellet, i.e. a ball of a number of grains, as well as a single grain.
In the production of breakfast cereals, it is essential that the grains of the granular material are kept separate from one another as the pass through the flaking rolls. Otherwise, malformed flakes known as doubles, or strips thereof, result, which malformation is undesirable. In the case of known apparatus for the production of breakfast cereals, the granular material passes to the flaking rolls by way of a feed roll, the cylindrical surface of which may have flutes or pockets formed therein, the flutes being either straight or spiral and the pockets staggered.
Although the flutes and pockets assist to feed granular material to the nip of the flaking rolls, the formation of doubles and other undesired shapes still occurs.
SWS92.Y OF THE INVEfPTION According to the present invention, apparatus for feeding granular material to the nip of a pair of flaking rolls, comprises a hopper, disposed above the rolls, a magazine disposed between the hopper and the nip of the rolls, the magazine defining a plurality of passageways for conveying granular material from the hopper to said nip, and means for controlling the flow of granular material through the passageways.
The passageways are preferably divided into groups, and the means for controlling the flow of granular material through the passageways may be operable to interrupt flow through the passageways of one group while permitting free flow through the passageways of another group, and vice versa.
Such control means may comprise providing the magazine with two rows of passageways, and with two rows of apertures, one each side of the magazine, which apertures provide access to the passageways0 Each aperture locates a movable finger; the fingers being operable in such a way that the fingers on one side of the magazine are moved into their associated passageways in order to interrupt the flow of granular material therethrough, while the fingers on the opposite side of the magazine are withdraqn from their associated passageways, in order to permit free flow of granular material along the latter.
Alternatively, the magazine may be provided with a row of passageways for conveying granular material from the hopper to the nip, and a distribution control member perforated by a row of passageways operable to reciprocate along a path between the hopper and the magazine.
BRIEF DESCRIPTION OF TTIE DRATÇIN^GS An embodiment of the invention will now be described by way of example only, with reference to the accompanying drawings, wherein: Figure 1 is a fragmentary end view of apparatus for feeding granular material to a processing machine, Figure 2 is a fragmentary plan view of the apparatus, Figure 3 is a fragmentary front view of the apparatus, Figures 4 and 5 are side views of parts of the flow control fingers assembly, Figure 6 is a plan view of the flow control fingers assembly, Figure 7 is a sectional view, taken on the lines VII - VII of Figure 6, and Figure 8 is a view in perspective which illustrates a modification.
In the drawings, like reference numerals refer to like components.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT With reference first to Figures 1, 2 and 5, apparatus l,for feeding granular material to a processing machine (not shown) is illustrated. The apparatus 1 is for feeding granular material to the nip 2 of a pair of flaking rolls 3 and comprises a feed hopper 4, disposed above the rolls 3, a magazine 5 disposed between the hopper 4 and the nip 2, the magazine 5 defining a plurality of internal passageways 6a, 6b for conveying granular material from the hopper 4 to the nip 2, and means 7 for controlling the flow of granular material through the passageways 6a, 6b.
The passageways 6a, 6b are disposed in two substantially parallel rolls, (Figure 2). The passageways 6a, 6b are juxtaposed, a passageway 6a being disposed between a pair of adjacent passageways 6b. The passageways 6a form one group of passageways. The passageways 6b form another group.
The passageways 6a, 6b extend from top to bottom through the magazine 5, in a divergent manner. (See Figure 3). This arrangement ensures that granular material discharged from the magazine 5 is distributed over the full extent of the roll nip 2.
The passageways 6a, 6b are formed by grooves formed in opposite side surfaces of a plate 10, the grooves being covered by side plates 11, 12 secured to the side surfaces of the plate 10. At approximately one third depth of the magazine 5, (see Figure 3), oppositely-disposed slot-like apertures 21 are formed, to provide access to the otherwise closed passageways 6a, 6b. Only one set of apertures 21 is shown as Figure 3 is a view from one side only.
The apertures in the plate 11 locate resilient 'fingers 13. The apertures in the plate 12 locate resilient fingers 14.
Figure 2 shows the grooves defining the passageways 6a, 6b from above, as well as the fingers 13, 14 which are spaced to cooperate with the passageways. The passageways 6a, 6b diverge (Figure 3). In Figure 2 the fingers 13, 14 are shown in dotted lines.
The fingers 13, 14 are mounted on laterally-spaced bars 15 and 16 respectively. (See Figure 2). As shown in Figures 4 to 6, the fingers 13, 14 curve down towards each other. The ends of the bars 15 and 16 are interconnected by plates 17 which have grooved rollers 25 mounted on their outer sides. The grooved rollers 25 are supported for reciprocatory movement on linear bearings 26, which in turn are mounted by brackets 27 to the side frame of the apparatus 1.
As best shown in Figure 2, reciprocatory movement of the means 7, i.e. the assembly comprising fingers 13, 14, bars 15, 16 and plates 17 and rollers 25, is brought about by an actuating linkage 30 comprising rods 31 carrying bearings 32 which are located by journals 37 carried by the end plates 17. The rods 31 also carry bearings 33 which are eccentrically mounted on a rotatable shaft 34 journalled in bearing blocks 35, 36.
The shaft 34 is driven by an electrically powered motor. (Not shown).
Operation of the feeding apparatus 1 takes place as follows : The hopper 4 is filled with a supply of granular material in pellet form. The pellets enter the magazine 5 to pass, under the influence of gravity, down through the passageways 6a, 6b of the magazine to the nip 2 of the flaking rolls 3. Thie to the divergence of the passageways 6a, 6b towards the nip 2, the pellets leaving the passageways are distributed along the full length of the nip, thereby fully utilizing the output capacity of the rolls 3.
In order to control the rate at which the pellets reach the nip 2, with a view ro ensuring that no doubles occur, the control means 7 assembly is reciprocated whereby the fingers 13, 14 operate in turn to arrest the falling columns of pellets moving downwardly along the passageways 6a, 6b, and release pellets in passageways 6a so as to permit free flow therein as the reciprocatory assembly is moved in one direction, and then to release pellets in passageways 6b when the assembly is moved in the opposite direction.
The fingers 13, 14, being resilient, do not damage the pellets as they move in the slot-like apertures formed in the plates 11, 12, towards and away from the passageways 6a, 6b.
Figure 8 is an "exploded" view in perspective illustrating a modification, wherein apparatus la makes use of a magazine 5a, the upper end of which is closed by a plate 40 fixed to the upper end, the plate being perforated by a row of equi-spaced inlet apertures 41.
The apertures 41 comprise passageways for conveying granular material from the hopper 4 to the nip of the flaking rolls (not shown) disposed below the magazine 5a.
The apparatus la is provided with means 7a for controlling the flow of granular material through the apertures 41. The means 7a comprise a distribution control plate 42 perforated by a row of equi-spaced apertures 43 and actuator means 44 for causing the plate 42 to reciprocate along a substantially horizontal path, between the hopper 4 and magazine Sa.
The top plate 40 fixed to the magazine 5 5 is perforated by ten apertures 41 and the movable distribution control plate 42 by five apertures 43. Apertures 41 and 43 are of substantially the same size. The pitch of apertures 43 differs from those of the apertures 41. In this example, the pitch of the apertures 43 is spaced at twice the pitch of the apertures 41. The arrangement is such that as the distribution control plate 42 is reciprocated, the granular material falling from the hopper 4 passes through all the apertures in the distribution control plate, but then only through alternate apertures 41 of the magazine 5a, in a shuttlelike manner.
