Switzerland (CH) ( 19) 1975 in A ( 44) Complete Specification Published 16 Apr 1980 ( 51) INT CL 3 B 65 B 39/00 ( 52) Index at Acceptance B 8 C E 9 ( 54) METERING AND FILLING APPARATUS FOR PULVERULENT OR GRANULAR COMMODITIES ( 71) We, SIG SCHWEIZERISCHE INDUSTRIE-GESELLSCHAFT, a Swiss body corporate, of 8212 Neuhausen am Rheinfall, Switzerland, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:-
The invention relates to a metering and filling apparatus for pulverulent or granular commodities, having metering means disposed upstream, in respect of the direction of commodity flow, of a valve or shut-off means, through which containers are filled with commodity wherein the containers to be filled are brought automatically one after the other into a position below the shut-off means and each receives a quantity of the commodity during the opening time of the shut-off means.
Known apparatus of this type has the disadvantages that, during the filling of a container, the air displaced from the container by the commodity entrains a fairly large quantity of commodity, so that, despite the provision of an extractor bell, the entire filling station becomes dusty in a short period of time and frequently has to be cleaned Exhaustive investigation has shown that this is primarily attributable to the fact that the jet of commodity is directed perpendicularly downwardly and the air located in the contained is whirled away to all sides.
this turbulent motion is usually further increased by the form of shut-off means used, namely, two counterwise controlled sliders which open and close in a scissor-like manner above the container In practice, the working cycle of an apparatus of this type cannot be increased in excess of 100 fillings per minute since the turbulence prevents accurate filling of the container In order to avoid the said disadvantages, the metering and filling apparatus in accordance with the invention is formed so that the metering means is provided with a downwardly tapering mouthpiece formed with a lateral outlet opening and so that the shutoff means is provided to open and close the outlet opening, a control means for the shut-off means being provided so that the outlet opening is opened by the shut-off means only when lift means for raising a container located below the mouthpiece, has been raised to a predetermined extend to that with the container present on the lift means said container These measures provide excellent guidance of the air displaced from the container, thus resulting in a considerable reduction in the dust created, and permitting a significant increase in the rate of the working cycle.
An embodiment of the present invention is illustrated diagrammatically in the accompanying drawings, in which:Figure 1 is a vertical section through the metering and filling apparatus of the embodiment and Figure 2 is a section taken on the line II-II of Figure 1.
The illustrated apparatus serves to introduce metered quantities of granular or pulverulent commodity, such as flour, into containers 1, such as bags, cartons or the like The commodity flows intermittently downwardly in a vertical feed pipe 2 of circular cross section, by the action of a metering screw conveyor 3 accommodated in the pipe, when the screw conveyor is rotated through an angle of n 360 ‘, wherein n is a factor which may be a whole number or a fraction, the larger this number is, the larger the container 1 to be filled The bottom of the pipe 2 is provided with a concially tapering mouthpiece 4 having a lateral opening 5 which is closable by means of a flap 6 The flap 6 is secured at 7 to the bottom end of a sloping arm 8 whose top end is mounted on a horizontal spindle 9.
an \ 1 z tn I 1 565 087 The spindle 9 is mounted in a bracket 10 secured in a support 11 which is fixed relative to the frame.
One end of a rod 14 (not shown in Figure 2) is articulated at 13 to a crank arm 12 which is also secured to the spindle 9 The other end of the rod 14 is articulated at 15 to the top arm, 16, of a lever 16 ‘ whose hub 18 is pivotally mounted on a spindle 19 secured relative to the frame The bottom arm 17, of the lever 16 ‘ is biassed in the direction of the arrow 21 by means of a tension spring 20 A hub 22 of a bell-crank lever 23 ‘ is also pivotally mounted on the spindle 19 The l arm 23 ol the bell-crank lever, which is vertical when in the position shown in solid lines, has at its top end a locking lug 25 which overlaps the lever arm 16 and thus, when the arm 23 is in its aforementioned vertical position, prevents the lever 16 ‘ from being pivoted in a clockwise direction as viewed in Figure 1 by the tension of the spring 20.
The arm 24 of the bell-crank lever which is horizontal when in its locked position, is connected at 26 to the top end of a rod 27 whose bottom end is articulated at 28 to a lever 29 The lever 29 is pivotally mounted on a spindle 30 secured relative to the frame and carries a follower roller 31 which is maintained in contact with the periphery of a cam 33 by means of a tension spring 32 attached to the lever 29 When the follower roller 31 moves from the small portion of the periphery having the greater radius r, to the large portion having a smaller radium r 2 upon rotation of the cam plate 33, the lever 29 follows the tension of the spring 32, so that the rod 27 pivots the ball-crank lever 23 ‘ to move the arms thereof into the position 23 “, 24 ” shown in dash-dot lines, in which the lug 25 moves away from lever 16 ‘.
The lever 16 ‘ can now follow the tension of the spring 20, so that the arms 12, 8 mounted on the spindle 9 are pivoted in an anti-clockwise direction and thus move the flap 6 into the open position 6 ‘ These movements are indicated by respective arrows in Figure 1.
The commodity delivered by the rotating screw conveyor 3 now flows laterally in the direction of the arrow 34 from the mouthpiece 4 into the container 1 thereby to displace the air in the container 1 so that the air escapes from the container on the other side of the moutpiece 4, i e in the direction of the arrow 35 The metering screw conveyor 3 is controlled in synchronism with the cam plate 33, such that the screw conveyor rotates for as long as the follower roller 31 is located on the portion having the smaler radius r, (flap 6 open), and the screw conveyor stops when the follower roller 31 comes into contact with the portion having the greater radius r, (flap closed).
The container 1 rests on a lift means constituted by a plunger 36 which raises the container into the illustrated filling position in which the mouthpiece 4 is positioned within the container When the plunger 36 is positioned in its bottommost position 36 ‘, the containers 1 ‘ to be filled are pushed in turn from an input path 37 onto the plunger 36 by means of drivers (not illustrated) secured to, for example, a chain which is moved intermittently After the container 1 has been raised and filled, the plunger 36 is lowered again and the filled containers 1 are further conveyed along an output path 38.
In order to prevent the flap 6 from opening before the container 1 has reached the filling position in which the mouth-piece 4 extends into the container to assume the filling position, a latch 39 also cooperating with the lever 16 ‘ is provided in addition to the locking lug 25 controlled by the cam plate 33 The latch 39 is located at the free end of a lever 41 which is pivotally mounted at 40 and which is articulated at 42 to the armature of a solenoid 43 secured relative to the frame When the plunger 36 is raised to its position during filling of a container, a contact 44 mounted thereon closes the electrical circuit 45 of the solenoid 43 which, by retracting its armature, pivots the lever 41 into its unlocking position 41 ‘ Alternatively, the plunger 36 can switch the electrical circuit 45 in some other manner, for example, by means of a magnetic proximity switch.
The flap 6 can be opened by the spring 20 only when both the locking lug 25 and the latch 39 are in their release positions 25 ‘ and 39 ‘ The spring 20 is tensioned and the flap 6 is closed when the follower roller 31 again moves into its illustrated position on the cam plate 33, the top end of the lever arm 16 returning to its initial position below the lever 41.
The illustrated apparatus also operates satisfactorily with a higher working cycle than 100 fillings per minute, for example, a working cycle of 150 fillings per minute, and only a very small quantity of flour, or the like, is entrained by the air flowing out of the container 1.
Advantageously, this flow of air can be received by an extractor bell (not illustrated).
By way of example, instead of using the screw conveyor 3 for metering the commodity, a drum of any other type of know metering device may be provided which charges the feed pipe 2 with metered portions of the commodity.
The control device 7-33 for actuating the flap 6 operates substantially more accurately than the solenoid-valve controlled pneumatic cylinders which hitherto have been conventionally used for actuating the shut-off 1 565 087 means and which operate too inaccurately in the case of a working cycle rate of more than containers per minute.
