Dosing device for fine powder or powdery good.

LIl

The innovation concerns a dosing device for Finely powdered or powdery goods, in particular for finely powdered or powdery foodstuffs or luxury items * such as powder cocoa with a fixedly attachable one that extends downwards Emptying nozzles having frame and a relative to this frame rotatable, the removal from a da-

overlying powder container controlling the metering slide.

Such metering devices are numerous Embodiments already known.

In German patents 745 720 and 59065 as well as in the German utility model documents 6 904 294, 1 856 308 and 1 845 603 are each metering devices for a wide variety of powdery goods as well described in smaller as well as larger dimensions, which essentially a trough-like to a horizontal one Have axis rotatable cylindrical barrel or such a cylindrical slide, which in each case the powdery material from an overlying feed channel pick up and with a rotation of 180 ° while at the same time closing the inlet channel, the material is placed in an underlying one Hand in the drainage nozzle. There are also such metering devices are known which each have several metering chambers in a cylindrical metering body rotatable about a horizontal axis.

In the case of the one described in the utility model 6 904 294 Dosing device is such a device, in particular for dosing powdery or granular ones

Food or luxury foods, such as powder B

coffee. This known metering device has a: |

have a steep slope angle, it happens when filling the metering slide in the one above existing powder supply to a funnel formation, so that after several withdrawals have been made from the powder supply, the metering slide is completely filled is no longer guaranteed and this consequently fails to serve its purpose.

In the case of the German utility model 1 856 Dosing device described, in particular for the dosage of pickling and incrustation powder for Seed dressing machines are intended, means are already provided to address the difficulties just mentioned Avoid the same with such pickling and encrusting powders appear. This is done in the known arrangement in that above the cylindrical to a horizontal axis rotatable metering slide also revolving around a horizontal axis Wire stirrups formed stirring basket is arranged, and that also the removal funnel periodic impacts is exposed. Such an undoubtedly effective device, however, is suitable because of its large technical dimensions Effort and the requirement of a special drive device both for the stirring head as well for a shock vibrator only for large dosing devices, such as

they are used for pickling and encrusting powders, for example Application finder for seed dressing machines. PUr small dosing devices, such as those used in particular for dosing of powdered food and luxury items in the household and are used in the catering industry, the great technical and energy-related effort is well worth it mentioned known arrangement not.

The aim of the innovation is to solve the problem of avoiding the difficulties that arise from the steep angle of slope of fine-grained and strongly adhering types of powder, especially in household or restaurant metering devices for powder-like luxury items, and that the emptied metering slide is always completely refilled to ensure after completion of the removal process, in view of the intended use of the metering device according to the innovation, emphasis is placed on a cheap, simple and easy-to-clean construction.

In terms of solving this problem, the innovation includes a metering device for finely powdered or powdery goods, in particular for finely powdered or powdery foods or luxury foods, such as two

For example powder cocoa, with a stationary attachable, a downwardly extending emptying nozzle having frame and a relative to this frame rotatable, the removal from an overlying powder container controlling the metering slide, which is characterized according to the innovation in that
this has several metering slides arranged in a ring around its vertical slide axis of rotation and penetrating it in the vertical direction
is connected to the powder container that the latter takes part in the rotary movements of the former, and that between this powder container and the metering slide a horizontal cover plate is arranged, which in turn rotatably at the upper end of a detachable, but rotatably connected to the frame, the metering slide centrally penetrating pivot pin is arranged and is preferably shaped like a sector of a circle so that it closes off the dosing chamber located above the emptying nozzle from the powder container and at the same time releases at least one dosing chamber from the powder container.

The metering device according to the innovation has, in particular, compared to the metering device according to the German Utility model 6 904 294 the progressive effect,

that there is a funnel formation within the powder supply even with continued metered removal can not come because the powder material supply located in the powder material container always with almost his full weight on the metering chambers not covered by the cover plate, and that so to speak within the powder supply a number corresponding to the number of uncovered metering chambers formed by "powder columns" in the powder supply is, of which one when turning the metering slide by one division through the horizontal cover plate is "cut off".

A great advantage is the fact that the metering device according to the invention consists of only a few, simply shaped There is share and consequently can be designed in its practical implementation so that it is easy Can be dismantled and cleaned.

In the metering device according to the innovation, a solidification of the powder material in the metering chambers of the Metering slide excluded, as these metering chambers push through the slide continuously in the vertical direction and in this way a constant, intermittent "passage" of the powder material through the dosing chambers takes place.

The innovation will now be described in detail below with reference to the attached drawings For example, described on the basis of preferred spatial shapes. In the drawings show:

The illustrated in Figures 1 to 3 of the drawings The spatial shape of the metering device according to the invention has a preferably hot washable plastic or made of metal frame 1 on "which, for example, by means of two" each have a common piece with him forming angular pin 2 in a holding device each having a corresponding vertical insertion slot 3

recess 4 of a wall plate 5 can be fastened. the Wall plate 5 can, for example, be the wall of kitchen furniture or the wall of a dining car or aircraft kitchen area.

The frame 1 has a metering slide 7 which can be rotated relative to this and which controls the removal from an overlying powder container 6, and a metering slide 7 drainage port 8 extending downward from the frame 1.

The dosage slide 7 has a continuous cylindrical bore along its vertical axis of rotation on. A plurality of identical metering chambers 10 are arranged around this bore 9 in a ring-like manner, which enforce the metering slide in the vertical direction and each have at most the same clear width have, like the emptying nozzle 8. The selected clear width of the metering chambers determines next to the size of the dosage amount of the powder.

The metering slide 7 »which is firmly connected to the powder container 6 above so that it that the latter takes part in the rotary movements of the former, is around a vertical, the bore 9 of the dosing

Fixed pivot pin 11 passing through the slide, which the latter is releasably attached to the lower part of the frame 1 in a manner described in more detail below is rotatably arranged. Between the powder container and the metering slide 7 is on the upper face of the latter almost adjacent, a horizontal cover plate 12 is arranged. The one with a smaller diameter formed upper part 13 of the pivot pin 11 is on the I,

lower end provided with an external thread to which | a suitable nut 14, which is used to fasten the cover disk 12 to the pivot pin 11, is screwed on. The cover plate 12 is shaped in the shape of a sector of a circle in such a way that it is located above the emptying nozzle 8 ^{: the} dispenser chamber 10 closes off from the powder container 6 and at the same time closes off at least one other;

Releases dosing chamber opposite the powder container.

The part of the fixed pivot pin 11 provided with the smaller diameter is at its upper one End with a screwable ball 15 made of metal or Plastic. These last two parts together form a handle, softer in the bulk goods container from the metering slide protrudes upwards so far that it protrudes from one through the mouth of the powder container grasping hand can be grasped.

The pivot pin 11 is provided with a pin 16 at its lower end adjacent to the drainage port 8 provided, which latter has a smaller diameter than the pivot pin 11 and by a suitable Center hole 17 protrudes through the bottom of the frame 1. A cylinder pin 18 runs somewhat offset in the center and perpendicular to the axis of the pin 16 therethrough. According to the illustration in Fig. 3 is in the In the middle of the bottom of the frame 1, an elongated hole complementary to the position and cross-section of the cylindrical pin 18 appropriate. The underside of the bottom of the frame 1 is immediately adjacent to the bore 17 and around Rotary stop 20 offset by 90 ° with respect to the longitudinal axis of the elongated hole 19 is provided. The elongated hole 19 runs perpendicular to the common center line of the bore 17 and the drainage port 8 and the rotary stop 20 is attached in the direction of this common center line. The bore 17, the pin 16, the cylinder pin 18, the elongated hole 19 and the rotary stop 20 together form a plug-in thread that holds the pivot pin (11, 13, 16) always in the same position. That will described in more detail below.

The powder container β and the metering slide 7 form in this, as shown in FIG. 1

up to 3 three-dimensional shape described a common part, which is made by joining a separately manufactured powder container and metering slide or can be produced in a single operation, for example, as an injection molded part.

The K ¹ material container 6 is provided at its lower end, ie directly above the metering slide or directly above the cover disk 12, with two driver ribs 21 diametrically opposite one another and extending vertically in the radial direction. These driver ribs 21 form a common part of the powder container or are each produced separately and subsequently connected to the powder container. The greatest possible length of the driver ribs 21 results from the distance between the outermost edge of the fastening nut 14 and the inner edge of the powder container. The driver ribs 21 are attached to the powder container 6 as shown in FIG. 2 with respect to the metering chambers 10 in the metering slide 7 so that they each run between two of the metering chambers 10 and thus do not lie above the filling openings of the metering chambers.

The metering slide 7 is on the outer circumference of its upper edge, i.e. at the transition from the metering slide 7

to the powder container 6, provided with a collar 22 in which the same number of indentations are incorporated, how dosing chambers are present and which with a holding pin 23 firmly connected to a frame hinged spring 24 cooperate in such a way that this spring 24 engages in the relevant recess, and holds the metering slide in place when one of its metering chambers is aligned with the emptying nozzle.

The mode of operation of the above with reference to FIG. 1 The three-dimensional shape of the metering device according to the innovation described to 3 of the drawings is as follows:

The powder container 6 is filled with powder, for example powder cocoa, and then the frame 1 is fastened to this retaining wall in the position of use by inserting the two angular pins 2 into the respective slot 3 of the retaining wall 5. Since the spring 24 always holds the metering slide J in the position in which a metering chamber is connected to the emptying nozzle 8 and in which the remaining metering chambers are closed off from the frame towards the bottom and open towards the powder container at the top, the one in the powder container now falls 6 powder cocoa filling so far

- 14 -

down, that its lower part with the exception of the momentarily located above the drainage port 8, of the metering chamber covered by the circular sector-like cover disk 12, fills all the metering chambers 10.

The desired size of the powder cocoa quantity to be removed from the powder container 6 has already been achieved determined beforehand by selecting a metering slide provided with correspondingly large metering chambers. For example, a metering slide can be used which has metering chambers with otherwise identical dimensions with a smaller clear width than the drainage port 8.

If the removal of powder cocoa is to be started, the relevant removal vessel is, for example So a jug or a cup, placed under the drainage port 8 of the device. Then will the metering slide from the position shown in FIGS. 1 to 3 against the compressive force of the spring 24, which had previously been locked in one of the recesses 25 (in the three-dimensional shape shown in the drawings with four dosing chambers) rotated by an angle of 90 °. As a result, the dosing chamber previously located above the emptying nozzle 8 is removed from the bottom of the frame

- 15 -

tightly closed and released from the cover plate 12 towards the top. Fills by gravity this dosing chamber immediately with powder again. At the same time, the one in front of it, seen in the direction of rotation Dosing cannula located over the drainage port 8 rotated, whereby its lower opening is released through the frame base, while the previously free upper one Opening is tightly closed by the cover plate 12. This dosing chamber empties the contained in it Powder material into the container located under the emptying nozzle. Each metering chamber which has been emptied via the emptying port 8 only returns after a path from 360 back into this emptying position, thereby ensuring that the metering chambers are always filled correctly. The powder material and the powder material container as well as the metering slide show no relative movement when rotated against each other.

The powder material only slides into the dosing chambers in an area outside the sector-shaped cover disk after. With the help of the driver ribs 21, which are firmly connected to the powder container 6, is prevents powder material from collecting over the cover plate 12. After one revolution of the powder container or the metering slide clear these each time by 18 ©

- 16 -

Driving ribs the space above the cover plate, respectively once off. This prevents powder material that has not been moved from sticking together over the cover plate and a complete emptying of the powder container is guaranteed.

If the metering device according to the innovation is to be cleaned, it is removed from the retaining wall and the handle formed from the ball 15 and the upper part 13 of the pivot 11 is rotated against the stop 20 shown in FIG. 3 until the with the pin end l6 connected cylinder pin l8 covers the elongated hole 19 in the frame base. In addition, the metering slide or the powder container are rotated so that none of the driver ribs 21 is located above the cover plate 12. If this is the wall, the common component formed from the ball 15, the upper pivot part 13, the nut 14, the pivot 11, the cover plate 12, the lower pivot part l € and the cylindrical pin l8 can be axially upwards out of the frame or pulled out of the powder container. The powder container can now be removed from the frame 1 upwards together with the metering slide after the spring 24 has been pulled out of the recess 23. Now all parts can be rinsed thoroughly with hot water and individually

- 17 -

be reassembled accordingly after appropriate drying.

Since the device according to the innovation consists of only a few parts, which in terms of their shape are simple, the device takes little time to disassemble and all parts can be cleaned thoroughly so that there are no white ticks are left over and so the hygienic requirements are taken into account to a large extent. Because losing weight the device according to the innovation of the retaining wall or the reattachment of the same to the retaining wall is very simple, claims the respective use or putting the device according to the innovation out of operation takes little time and effort.

The actual removal process only consists of

a simple rotation of the metering slide 7 by hand

ο around 90 and is therefore extraordinarily simple and short. The dosing device according to the innovation is in It is very easy to use and also time-saving, since every removal process simultaneously does Filling at least one other metering chamber means.

Because of its simple structure, the manufacturing costs of the metering device according to the invention are very high

- 18 -

low, so that these brought to the market cheaply can be. The hygienic requirements, in addition to the already mentioned simple structure, is the innovation according to Device also taken into account that its individual parts are either made of metal or of hot water resistant Plastic can be made.

Some modified spatial forms of the modern ones Dosing devices will now be described in detail, for example, with reference to FIGS. 4 to 8 of the drawings described. 4 to 8 only the parts of the metering device according to the invention are shown which compared to FIGS. 1 to 3 are modified. In FIGS. To 8, the same parts are given the same numerals Mistake.

Fig. 4 of the drawings shows one in principle Structure similar to the three-dimensional shape shown in FIGS. 1 to 3 of the metering device according to the invention Device which, however, instead of the powder container firmly connected to the metering slide, has a screw-in, Commercially available powder container 26 has. In this modified three-dimensional shape, the metering slide has a mouth rim 27 that extends up to above the driver ribs 21.

- 19 -

If the powder container 26 in question is a glass, ceramic or plastic vessel with a screw thread or plug-in thread opening, the connecting piece 27 is provided with a corresponding internal thread 28 into which the
Muzzle thread of the powder container concerned can be screwed in or pushed in. The mouth thread ends at an inner collar of the cylindrical connection piece 27. A sealing ring 29, made of elastic, hot-washable, is expediently on this collar
Material applied to which the mouth edge of the powder container concerned is pressed when screwing in or pushing it in.

The mode of action of this three-dimensional shape described in FIG. 4 corresponds essentially to that in the Pig. I to 3 described spatial shape. It differs from this only in the way in which the dosing device is filled with powder: the dosing device is removed from the retaining wall and held freely in the hand. After unscrewing the cap from the commercially available one
Powder container 26 is the meanwhile with its upper side turned downwards frame 1 with your internal thread of its powder container connecting piece 27 instead of the closure cover on the external thread of the mouth

- 20 -

Powder container 26 screwed on until the edge of the mouth is close to the ring seal 29 of the powder container connector 27 creates. Then the frame 1 together with the screwed to it, completely with, for example Powdered cocoa filled powder container 26 is rotated back into its normal position and the frame 1 through Reintroduction of the angle pin 2 into the insertion slots 3 of the extension 4 of the retaining wall 5 again attached to this retaining wall in the position of use.

FIGS. 5 to 8 show two further modified three-dimensional shapes compared to the metering device according to the invention shown in FIG. 4. *, \ these three-dimensional shapes, the connecting piece 27 is designed only so high in the axial direction that it receives the mouth thread 28 for fastening a commercially available powder container 26. Since these two three-dimensional shapes are no longer provided with the driver ribs 21 described in FIGS. 1 to 4, so that clearing of the cover plate is no longer guaranteed as a result, according to the modified three-dimensional shapes of the innovation, this cover plate has such a spatial design, that an immovable accumulation of powder is avoided on the cover plate.

- 21 -

As shown in FIGS. 5 and 6, the Cover plate 12a spatially designed so that the upper cover surface of the cover plate with respect to the lower Top surface rises like a ramp in Itafangsriehtung. This particular type of construction of the cover plate 12a is shown in perspective in FIG.

When the powder container and metering slide 7 rotate together, the cover disc 12a acts like a plow on the powder material and thereby prevents each other above her a "column" of powder accumulates, the one would prevent complete emptying of the dosing device.

In the modified three-dimensional shape shown in FIGS. 7 and 8, the cover plate 12 is provided with a conical attachment 30, which also has a Accumulation of powder over the cover plate 12 is prevented.

The use and cleaning of the in the Flg. 4th to 8 shown modified spatial shapes of the metering device according to the innovation is designed analogously as that of the spatial forms described above.

The dosing device according to the innovation was above

- 22 -

consistently described in connection with manually operated metering slides. Needless to say, the innovation also extends to three-dimensional shapes in which the metering slide is motorized or in a manner known per se are moved electromagnetically. But as far as such motorized or electromagnetically operated metering slides in Combination with one or more of the above-described features that characterize the innovation are used, they are to be regarded as falling under the innovation.
