Description
June 11, 1935. A. ANDREAS FILLING umcanm Filed Jan. 12, 1950 2 Sheets-Sheet 2 II n ' Inventor- Arno Andreas Patented June 11, 1935 Application January 10, 1930, Serial No. 419,986 In Germany September 23, 1929 38Clalms.
My invention relates to filling machines, particularly intended for automatically filling equal quantities of powdery or granulated material into automatically closing valve bags, or other containera.
For automatically filling such material into bags several methods are known and it is common, too, to use several sorts of arrangements for executing such methods, but they are not satisfactory, as they require excessive space,
while not being capable of compactly packing 1 required for slowly filling the weighing recepaccurate weights of material in the bags. Moreover, they have required too many motions on the part of the operator.
My invention is also concerned with weighing the material first and afterwards conveying it by suitable means into bags, while their bottoms are l ned, the bags being supported on a device gillzsted to be tilted when the bag is completely IIhe invention relates more particularly to machines for fillingvalve bags or other receptacles, including a feeding apparatus disposed above a receptacle suspended upon the balance arm of an. automatic weighing machine, and a conveyor, such as a propeller below the weighing receptacle, for accelerating the fiow of material leaving the receptacle, so that it is carried with high speed into the bag and becomes tightly packed therein, while the bag. is jogged up and down. When the bag is filled, the bag supporting device or rack is tilted by the weight of the bag about an appropriate axis.
Although there is disclosed means for automatically releasing the bag supporting rack after -a predetermined time, to effect discharge of a bag, and although this operation maybe accomplished invany suitable manner other than that shown, I prefer to construct the machine so that the bag is discharged only upon actuation of a manually operable handle.
In order to gain. on the one hand, the time tacle to obtain very accurate weight, and, on the other hand, the advantage of needing only one man for filling a greater number of bags in a given time, my invention concerns several units, of the character described, disposed side by side or in bank and connected in such a manner that the rack releasing means of one unit opens the outlet of the weighing receptacle of the next=unit from which a filled bag has just been removed and replaced by an empty bag.
By my invention, I am able to stir the materialas ,itis continuously fed-to the machine and as it passes therethrough, and regulate the feed as required in every part thereof, so that the machine cannot become clogged. Also the material can be weighed with utmost precision and packed so compactly that bags somewhat 5 smaller than usual may be used, the cost of packaging being thus decreased. The compact packaging thus achieved prevents the bagged material from sinking down in transportation so that the bags arrive only half filled. This 10 initial compact packaging is of great importance when bagg a material like cement which tends to settle for some time after 'it has been mingled with air to a dusty emulsion.
By constructing the whole apparatus to oper- 15 ate automatically, from the entering of the material to the throwing of! of the filled bags, I obtain a very large capacity because the operator has but to survey the operation and mount empty bags upon the filling nozzles, (if this is 20 not efiected automatically, too)' the machine thus requiring a minimum of manual labor.
However, as already indicated, it is preferable to operate the machine semiautomatically, that is to say, so that the attendant, in addition to putting empty bags in place, need only actuate a single lever for starting the filling operation in one unit and discharging a bag in another.
My invention thus aifords a great many advantages both technical and economic. preventing the escape of dust the whole arrangement may be hermetically enveloped and provided with devices which convey any escaped material to collectors whereby loss of material .and creation of a nuisance are prevented.
My invention has for another object the provision of such further improvements and novel devices as are shown, and described in the following specification.
\ The invention is illustrated in the accompany- 40 in: drawings, wherein- Fig. l is a side elevation, partly in section; Fig. 2 is a front elevation.
In order better to show the important fea- .tures of the mechanism, some parts lying on 5 are marked by like numbers distinguished by 5 Referring to the drawings, I secure to a casement 2 an inlet pipe I through which the material enters a screen drum 3, where heterogeneous pieces are separated to be carried off through the outlet 4, while the screened material is whirled up and removed by the spiral conveyor 5 to the discharge 6.
In the machine illustrated in the drawing, I provide three units each including a discharging device and a filling arrangement one of which I will describe in detail.
In the outlet 5 which is, in a well known manner, laterally inclined in order to discharge the material always equally and without any clogging, I provide a slide 1 which permits regu lation of the flow of the material.
At the bottom, the outlet 5 is shut by two cylindrical valves, in the upper one 5 of which I provide an opening that is closed by the lower valve 9.
Below the outlet 5, I support a receptacle I ll upon the scale-beam ll pivoted on the standard l2 and balanced by the weight l3. A lever l4 secured to the receptacle l5 stops the lever l5 pivoted on the shaft I8 near the outlet 3 and bearing the valve 8.
At the standard I 2, I provide on the ioumal l1 an arm it! which is stopped by the lever-l5 and connected by means of the rod 25 with the lever 2| likewise mounted on the shaft l5 and bearing the valve 9.
The bottom of the receptacle I0 is closed by a valve 22 fixed by an elbow link 24 pivoted at 23. Below the receptacle ill, the hopper 25 is secured to the standard l2 and a propeller. 25 is mounted in the mouth of the hopper which terminates in the nozzle or spout 21.
The inner walls of this hopper are preferablyof the standard I2, I dispose the double lever 32 the rear part of which bears with the roller 33 against the cam 35 fixed on the shaft 34, the fore-ends of said double lever supporting the bag bearing rack 31 by means of the verti-- cal regulating screws 36. 1
The top-of each screw 35 is joined by a rod 38 to the arm 39 fulcrumed likewise on the shaft 3| and fixed by a hook pivoted at" in the standard l2. By means of the rod 4|, the hook 42 is joined with the cam and withthe handle 44 fulcrumed on shaft 43 on the hopper 25.
On shaft 43, too, a clip or bag clamp 41 is mounted provided with an elastic border 45. The handle 44 is connected with the pawl 43 which engages the ratchet 45 joined to the link 24.
The arm 39 is attached to spring 55, for purposes which will be apparent from the following description of the operation of the machine,
. and another braking spring 5| is opposed to it.
In front of the filling arrangements I provide a conveyor belt 52 running on rollers 53, a pedestal 54 and a balustrade or railing 55.
I will now describe the operation of my invention.
- The material. leaving the drum 3 enters the receptacle l0 and assembles there, shifting the scale beam so that the lever l4 releases the lever |5 which closes the valve 5 and nearly wholly interrupts the discharge stream so that only a little material can still pass down through the opening in the valve 5. The scale beam continues turning slowly till the projection on the weight l3 engages the lever I8 and releases the arm I3 which in turn revolves around its journal l1, bowing the elbow formed by the arm 13 and the rod 25. Thereby the lever 2| is quickly rotated down and the valve 9 interrupts suddenly the late stream of the material.
By known means which are not illustrated here the valve 22- is kept fixed till the weighing receptacle II is completely filled; only then is it possible for valve to be opened by the weight of material whereupon the material assembled in the receptacle I5 streams into the hopper 25 and is removed therefrom at higher speed bythe continuously revolving propeller 25, through the nozzle 21 into the valve bag 5.5. At the same time, the levers bearing the valves 3 and 5 are put back to the initial position by well known means .not illustrated in the drawings.
In orderv to prevent the material, as it is whirled by the rapidly revolving propeller from powdering out from the hopper, I have provided the oblique edges 53 and the transverse ledges 51, 53, 59 in several levels for making the material coming from above descend and for keeping back such as is rejected from below; The ledge 55 receiving the chief push of the material is preferably slack and elastically mounted so that it is able to oscfllate for pushing of! dust bottom of which is supported on the rack 31- while its back bears against a suitable bar secured to this rack. By the thickened lower part 35 of the nozzle 21 the valve of the bag is hermetically closed and the bag is further prevented friomngliding down by the border 45 of the c p v The dust formed within the bag by the filling operation retires, together with the air driven out, through the drain 25 and is caught in the discharge 25. The continuous rotation of the shaft 34 moves the rack 31 perpetually up and down and constantly jogs the bottom of the bag, during the filling operation in order to stow the material tightly in the bag.
The periphery of the cam 35 is partly circular, the lifting curve extending only along a part of it; so, the rack 31 suddenly falling down after being lifted by the cam, reposes for a certain time before next lifting, so that the material contained in the bag stows most tightly on the bottom.
When the bag is filled, the hook 42 is raised by the rotary cam 45, the arm 35 then being maintained only by the spring 53. The force of this spring is adjusted so that the arm 39 is in the illustrated position when the rack 31 is empty, but is tilted when released and when the bag 5'3 is filled ofcontains sufllcient mate rial to over-balance the spring, because the center-of gravity of the bag is forward of the pivot, the bag being on the forwardly extending support.
The levers 32 being constantly moved up and down by the cam 35, the jogging of the rack 31 is still continued during tilting of the rack.
The rack- 31 then rotating around the axis 3| and, at the same time, around the lower.
corner of the parallelogram constituted by the 54 upon the conveyor belt 52. As the clip 41' is lifted at the same time automatically or by the handle 44, to raise the elastic border 46 from the bag, the latter can slide off the nozzle 21. In tilting, the arm 32 meets the braking spring and is rejected by this as soon as the bag is thrown off, being drawn back'at the same time by the spring 50.
The rotation of the cam 45 is regulated so that the bag is tilted down only when wholly filled with the weighed quantity of material. But the lever 4| may also be released by means of the handle 44, independently of the cam 45. When the bag is thrown off, the operator mounts another bag on the nozzle 21. When doing so, he finds a stay for his feet on the pedestal 54 while he leans back against the balustrade or railing 55.
Now. the different filling arrangements of the machine are so stepped and coupled that one apparatus is weighing while the weighed material in the next is bagged and the filled bag is being replaced by another bag in the third. If there are more than three filling arrangements, they are coupled and stepped correspondingly. Thus stepping the parts of the filling machine, I obtain a very large capacity without diminishing the precision, having plenty of time for weighing as well as for filling and replacing the bag.
The cams 35', 35", and 35" may be placed on the common shaft 34 so that the individual frames 31, 31" and 31" are jogged rhythmically one after the other.
- Now I will describe howthe rods are coupled which open the discharge valves of the weighing containers in and tilt the bags.
When I operate the handle 44', (Fig. 2), the ratchet 49" is released so that the discharge valve of container I0 is opened while the arm 39" is freed and the bag mounted on the nozzle 21 is tilted. Now'the operator puts an empty bag on the nozzle 21" while the bag previously placed on the nozzle 21 is filled.
By next operation, the handle 44" is moved to release the ratchet 49" for'opening the weighing receptacle I0" and filling the bag placed on the nozzle 21" in the previous operation; at the same time, the arm '39 is freed for tilting the bag supported on the nozzle 21".
The handles 44' and 44". are preferably secured to sleeves mounted on the shaft 43 and the pawls 48 and 48" as well as the rods 4|." and 4i" and the clips 41" and 41', respectively, are joined with these sleeves, while the handle 44" is directly fixed to the shaft 45 with the two ends of which the pawl 48", rod 4| and clip '41 and joined;
The whole mechanism is operated by the shaft 6|, onlythe propellers 26 of all. arrangements being fixed on a common shaft directly revolved by the electric motor 62.
The terms and expressions which I have employed are used as terms of description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any,equivalents of the f atures shown and described or portions thereof, but recognize that various modifications are possible within the scope of the ,inve ion claimed.
