I mscnnnome cnosunn roe MIXING MACHINES.
, Application filed July 8, 1926, Serial-No. 121,181, and in Germany November 13, 1924.-
This invention relates to an automatic discharging closure on mixers, stirring ma-v chines, mortar mills, slowly rotating cylinders and .the like for masses of any kind,
especially for ceramic masses, in which'in the bottom of the. mixing drum. an aperture is arranged in which a closing piece moved like a slide or aclosing piece moved like a slide and adapted to beraised and lowered is mounted. Stirring devices which move directly over the plate-like bottom push the material towards the aperture in the bottom through which it drops into a truck placed underneath.
The closing cover adapted to be raised and lowered may be arranged upon a carriage which, after the lowerlng, can be run out at the side, but'it'might be arranged to be oscillated from under the mixing drum in lateral direction.
hinged to a rod oseillatable around a pin and running by means of a roller upon an arc-shaped bar.
The closing cover together with a mechanism for adjusting in vertical directions might further be arranged in acasing suspended on a pivot pin underneath the mixing drum so that it can be oscillated in horizontal direction. The oscillatable arm has means and arrangements which permit of rapidly moving the closing cover upward and downward by one single manipulation and to bring the whole by a lateral pressure out of the area of the dischargin aperture.-
I The material resting upon' t 'e closing cover is, at the lateral movement, stripped off/by a projecting rim on the lower side of the mixing plate or by ,one or several ribs or the like mounted radially or obliquely upon the lower surface of the mixing plate. The discharging aperture ma be of any shape. It may, or. instance, be circular, oval or cornered.- v
The closing piece might further, instead of being in horizontal position, as in 'mixers, be inclined at any angle or arranged vertically, on other machines, if the conditions make this necessary. A
In mixers with rotary or stationary mixing trough the discharging aperture is arranged at the centre of the bottom plate and the closing cover is arranged'on a carriage adapted to .be pulled out in lateral direction from under the bottom late so that said s closing cover canbe raise and lowered.
The ascending and descending movement The closing cover is of the closing cover may be controlled by a lever-mechanism, rack or by means of screw spindles or the like.
The rotation of the crankshaft for raising and lowering the closing cover is effected. by hand. The reciprocating movement of.
the carriage for removing the cover in lateral direction may be effected by hand or mechanically, for instance from the driving shaft of the mixing plate by means of friction roller.
Several forms of construction of the machine are shown, by way of example,in
' the accompanying drawing, in which:
The Figs. 1 to 10 show various forms of construction of mixers with automatic emptying closure in the bottom of the mixing .plate.
Fig. 1 is a vertical section through the mixer with'closingcover in the emptying aperture and'friction driving gear of th'ecarriage.
Fig. 2 shows in plan view the friction gear for driving the carriage. 1
Fig. 3 shows the closing cover in the open positlon. y
Figs. 3 and 3" show in section and in side elevation respectively the closing cover adapted to be raised and lowered and on larger scale. Fi 4 shows in plan view seen from below t he mixing trough.
Fig. 5 is a section on line AA of Fig. 'Figs. (Sand 7 show diagrammatically the oscillatable closing cover in plan'vicw seen from below and in section respectively.
Fig. 8 shows the closing device on rotating cylinders o'r the like.
Fig. 9 is a vertical longitudinal section through the devic with oseillatable arm.
Fig. 10 shows in plan view seen from below the device shown in Fig. 9. f
The mixing trough a runs on rollers 0 and it is rotated b .a toothed wheel 12 meshing with a to'othe crown 6 At the center of the bottom plate aka discharging device d (see'Fig. 3) is arranged in which a closing cover 6 is mounted which is adapted. to 'be raised and lowered and to be shifted to the side. To better guide the closing cover 6 this cover and the aperture are fitted with rings 9 of angular cross section. In the i closing position the closing cover 0 bears by means of abutments f onto the ring 901? angular cross section of the aperture. On the lower surface of the closing cover further with a groove Z in the stud g and is o erated by a crank pin m on the crank sha t m which in its turn is rotated by the crank handle 2 A crank arm m rotates at this occasion in a cut-out portion 8, of a. sleeve i on the axle bushing 71,. By a halfrotation of the crank handle a, and of the crank shaft m the stud g, with the closin cover e are raised and lowered by the cran pin m and the slide block k in the rotating sleeve 2' which is adapted to execute a reciprocating movement in vertical direction. By an abutment 2 on and by two adjustable stops a (see Figs. 1 and 2) on the flange of the carriage the stroke of the carriage is limited. The bearings 0 and 0 of the crank shaft m are connected the one with the othei' by a tube 1). The bearing 0 forms one piece with the sleeve 11 of the-axle bushing The tube 2, which forms thefguide rod of the carriage, is enclosed at the other end by a stationary bearing z in which it slides to and fro if the carriage is pulled out in lateral direction, the closing cover'being lowered. V
The two carriage wheels 1' runs on flanges of U-irons 1', of the machine frame (see Fig. 5) and they are rigidly connected with their journals 5' rotating in the axle bushing z',. The "carriage is guided in lateral direction by the end faces of the journal axles 8 being guided on the webs 8 of the U-irons 13. In order to ensure accurate lateral adjusting of the closing cover e with regard to the discharging aperture Z,'the journals are shiftable in axial direction. They are held in the actual position by" means of spacing blocks is, clampedby means of pressure screws. The arrangement may be such that the carriage wheels rotate around the journals which are shiftably mounted on the axle bushing and so that they can be secured in the adjusted position. In the longitudinal direction the carriage wheels 1' butt against adjustable stops.
If "emptying of the mixing trough a has to take place the closing cover e is first, by
a half-rotation of the crank handle a, lowered invertical direction until its u per surface is flush with the lower surface 0 the mug 9' of angular cross section on the bottom of the plate. The carriage is then pulled out to such a distance that the carria e wheels butt against. a stop, the materia resting upon the closing' cover 6 being strip ed off an cleaned at this occasion by the ring 9 or by The discharging aperture d, is then quite free and the rotating mixing tools, WlllCh are not shown in the the crank handle 2,
drawing, push the material towards the discharging aperture (1,. After the emptying has been completed the carriage is ushed back and the crank handle a, is rought into the opposite position whereby the cover is ressed into the dischargingaperture d of the plate and closes the same. In the form of construction shown in Figs. 1 and 2 an arrangement for mechanical displacement of the carriage by a friction roller u is further illustrated, said friction roller being mounted on the driving shaft u, of'the, mixing trough a. Two bars '0 are fixed, one at each side of this roller u, on the tube p. A hand-levers operates an elbow' lever. At the end of each arm of this elbow lever a pressure 'roller '2), is. mounted, one or the other of these pressure rollers being pressed against the corresponding bar a if the hand lever '0 is inoved 1n the one or otherdirection, said roller '0 being thus brought into contact with the friction roller u. The carriage is consequently drawn along and shifted in the one or other direction. The crank, handle z, for lowering or raising the closing cover is operated by hand. 1
In the forms of construction shown in Figs. 6 an adapted td The closing cover e, together With'the mechanism for oscillating the same, is first lowered with the aid of a mechanism as hereinbefore described and subsequently oscillated in lateral direction. With this object in view the closing cover is hingedly connected by a bolt 1 to a rod 2. This rod is mounted in a bearing 4 adapted to be rotated around a stud 3, the other end of rod 1 carrying a roller 5, "which rests upon a curved bar6. After the closing cover has been lowered a crank handle 7 is rotated whereby the closing cover 6 is brought into the position 10 indicated in dash lines in Fig. 6.
This mechanism may be constructed so that no lowering of the closing cover is necessary. In this case the closing cover e consists of a smooth disk which closes tl1eaper-' tures in the bottom of the mixing plate.
Fig. 8 shows the closing cover e with carriage, mounted on a slowly rotating cylinder 8. In this arrangement the carriage 9', designed to make the closing cover e oscillate in lateral direction, rotates also. The mechanism comprising an oscillatable arm, as shown in Figs. 9 and 10, isconstructed as follows --The rotatable mixing drum 0 has at the center of its bottom plate I) a discharging aperture a In Fig. 9 the closing coverd is shown in the extreme lower position, from which it can be oscillated in lateral direction.
The closing cover at is mounted, by means of a stud e, in a bearing sleeve f which is arranged in a casing g. The casing g is oscillatably mounted on an axle h which is connected by a connecting element z to a 7 the closing cover 6 is shown as be oscillated in lateral direction.
U-iron k fixed underneath the mixing machine. The lowering and raisingof the closing cover (1 is effected through the inter mediary of an elbow lever pivotallyg, mounted in the casing g, theball-shaped end of the upper arm 1 of said elbow lever engaging with a cavity of the bearing f, a connecting rod nbeing hingedly connected to the end of the other arm m of said elbow lever. This connecting rod 1:. is mounted in a tube 0 which is fixed in a caslngin which the elbowleveris enclosed. The other end of the connecting rod 0 merges into a screw spindle p whichis screwed into an internally threaded sleeve 1-. This sleeve 7 is rotatably mounted on the flange 0 of tube 0 and it has a crank handle s. From this screw spindle 12 extends a rodp on the end of which two nuts t are screw ed which serve as stop for the crank handle, the other stop for said handle being formed by the end of the screw spindle 2. -If the crank handle 8 is turned in the one or other direction the rod n is either shifted to the left or right. The arm Z of the elbow lever is thus made to'raiscor lower the sleeve f with the closing cover (Z which is thus rapidly and in a simple manner brought into the desired position. If the closing cover clis in the extreme position the mechanism and the closing cover can be rotated around the stud k to liberate the aperture l, so that the material candrop out of the same.
