[0007] Title: Metering disc, filling device and method for
[0008] Dosing of material
[0009] Description
[0010] The invention relates to a metering disc for metering material according to the preamble of claim 1, a filling device for metering material with features of claim 8 and a method for metering material with features of claim 13.
[0011] To fill powdered material into a hard capsule, a method using a metering disc can be employed.
[0012] Such a method or metering disc is known, for example, from DE 10 2006 031 250 Al. In this process, the powdered material is pressed into a metering volume of the metering disc, thus generating a dose of the material within that volume. This then determines the metering quantity for filling the hard capsule.
[0013] The material to be filled can vary in particle size, moisture content, particle shape, true density, etc. This can lead to clumping and an uneven distribution of the material on the dosing disc.
[0014] It is therefore an object of the present invention to provide a metering disc for metering material, a filling device for metering material and a method for metering material, wherein the material to be metered or filled is distributed uniformly, in particular fluidized.
[0015] The above problem is solved by a metering disc for dispensing material, particularly powdered material, preferably in capsules, with the features of claim 1. The capsules can be designed as hard capsules or hard gelatin capsules. The hard capsules can consist, for example, of cellulose (HPMC) or other polymers.
[0016] The material in question may be a medicinal substance or a material with a medicinal effect. It may be a powder from the food industry (e.g., milk proteins, wheat, cornstarch, etc.) and / or a dietary supplement.
[0017] The metering disc comprises a top surface, the top surface of which is designed, at least in part, for depositing (or receiving) the material. The material can be arranged as a powder bed on the top surface of the metering disc. The top surface can be designed, at least in part, and in particular completely, as a flat or planar surface.
[0018] The metering disc includes a bottom surface. The bottom surface is positioned opposite the top surface. The bottom surface can be flat or planar, at least partially, and in particular completely.
[0019] The dosing disc comprises at least one dosing opening. The dosing disc may have multiple dosing openings. The dosing opening serves to dispense a dose of the material. In other words, a dose of the material, particularly to be filled into a capsule (e.g., a hard capsule or hard gelatin capsule), can be determined by the size or shape of the dosing opening and the associated dosing volume (before dispensing). The dosing opening may extend from the top to the bottom. The dosing opening may be sleeve-shaped. The dosing opening (especially its outer surface) may be surrounded by a wall. The dosing opening may be a bore. It is also conceivable that, for example, the depth of the dosing opening can be adjusted via a sliding base, thus allowing the dose to be preset (before the dosing process).
[0020] The top surface includes at least one blowing section. The blowing section is designed to blow gas, in particular air or compressed air, into the material (or material bed, powder bed) arranged on the top surface. The material can be arranged horizontally on the top surface.
[0021] The metering disc can be circular. It is also conceivable that the metering disc could have a different shape, e.g., polygonal, square, triangular, oval, etc. The gas can be an inert gas and / or noble gas (e.g., nitrogen, argon, etc.). The gas can be oil-free compressed air. The blowing section can be a perforated section or area of the top surface.
[0022] This allows for the fluidization or liquefaction of the material using simple means. The gas can surround the material particles (or powder particles), thereby eliminating or at least reducing the friction between them, and thus fluidizing or liquefying the material (or powder).
[0023] In this context, "fluidized" or "liquefied" means that the material (or powder) then behaves like a kind of liquid, resulting in a liquid-like material distribution on the metering disc.
[0024] The injected gas can directly influence the material properties and density. This allows the material to be made free-flowing for the moment of gassing or injection, which in particular enables a uniform distribution on the metering disc.
[0025] By using inert gases, such as nitrogen, the material can also be filled in a protective atmosphere, which increases the shelf life of the products. In particular, oxygen-sensitive materials can be dosed in this way.
[0026] According to a further development of the metering disc, the blowing section can comprise at least one fabric element. The fabric element can be gas-permeable. The fabric element can be configured for blowing gas, in particular air or compressed air, into the material arranged on the top surface. The fabric element can be impermeable to the material. The fabric element can be flat. The fabric element can be plate-like. The fabric element can extend over a plane. The fabric element can be designed as a fine mesh grid. The fabric element can have a shape corresponding to the top surface of the metering disc (e.g., circular). The fabric element can comprise or be made of fluidizing fabric. The fabric element can be made of textile, plastic, and / or metal.It is also conceivable that the fabric element could be designed as a sintered plate.
[0027] This allows the blowing section to be implemented using simple means. In particular, the penetration of material through the blowing section into the metering disc can be prevented using simple means.
[0028] According to a further development of the metering disc, the blowing section can comprise at least one blowing opening. The blowing opening can be configured for blowing gas, in particular air or compressed air, into the material arranged on the upper surface. The blowing opening can be gas-permeable. The blowing opening can be impermeable to the material. The blowing opening can be configured as a bore. The blowing section can comprise a plurality of such blowing openings. The blowing section can be perforated by a plurality of blowing openings.
[0029] This allows the blowing section to be implemented using simple means. In particular, the penetration of material from the blowing section into the metering disc can be prevented using simple means.
[0030] According to a further development of the metering disc, the blast opening can be designed as a through-opening oriented perpendicular to the top of the metering disc. In this context, the orientation of the through-opening refers to the orientation of the central longitudinal axis of the blast opening. The blast opening can be sleeve-like, for example, in the form of a cylinder, whereby a lateral surface or a side wall of the blast opening can be oriented perpendicular to the top of the metering disc. The blast opening can be oriented parallel to the direction of gravity. In this context, the direction of gravity refers to the direction of gravitation (downwards towards the Earth).
[0031] This allows the blowing opening and thus the blowing section to be implemented using simple means.
[0032] According to a further development of the metering disc, the blowing opening can be designed as a through-opening oriented towards the top of the metering disc.
[0033] The central longitudinal axis of the blowing opening and the upper surface of the metering opening can form an angle of inclination less than 90°. The central longitudinal axis of the blowing opening and the direction of gravity can also form an angle of inclination less than 90°. With multiple blowing openings, it is conceivable that at least two blowing openings, in particular a predominant portion of the blowing openings, and furthermore, in particular all blowing openings, have a different orientation or a different angle of inclination.
[0034] This allows the gas injection to be precisely controlled. By varying the angle of the blow-off opening, the inlet direction can be influenced with simple means.
[0035] According to a further development of the metering disc, the blow opening can have a cross-section that tapers towards the material arranged on the top surface, e.g., a conical cross-section. The blow opening can have a cross-section that tapers against the direction of gravity, in particular a conical cross-section. The blow opening can, in particular, be designed as a nozzle.
[0036] This allows for a higher injection velocity of the injected gas using simple means.
[0037] According to a further development of the metering disc, at least one cavity, and in particular several cavities, can be arranged between the upper and lower surfaces. The cavity, the fabric element, and / or the blowing opening can be fluidically connected to each other. The metering disc can be configured such that gas, in particular air, or...
[0038] Compressed air is first passed through the cavity and then through the fabric element and / or through the blow opening. The cavity can be designed as a chamber within the metering disc. The cavity can be defined or limited, in particular, by the top and bottom surfaces of the metering disc.
[0039] The fabric element can be attached to the blowing section or the top of the metering disc by means of clamps, adhesive bonding, and / or screws. The fabric element can also be attached to the blowing section or the top of the metering disc in a reversibly detachable manner.
[0040] This makes it possible to blow in gas, especially air or compressed air, using simple means.
[0041] In this context, a fluidic connection means that a gas, in particular air or compressed air, can flow between two elements in fluidic connection.
[0042] The metering disc may have an opening, in particular a centrally arranged one. The opening may be designed to receive a shaft by means of which the metering disc can be rotated about an axis of rotation. The shaft may be a component of the metering disc or a component of a filling device described below.
[0043] The above problem is further solved by a filling device for dosing, in particular powdered, material, preferably in capsules (e.g. hard capsules or hard gelatin capsules), with the features of claim 8.
[0044] The filling device comprises at least one metering disc as described above. The filling device includes a cone, which is conically shaped and designed to distribute the material on the surface of the metering disc. The filling device includes a shaft. The metering disc and the cone are rotationally fixed to the shaft, in particular, connected to it. The metering disc and the cone are rotatably arranged or mounted about an axis of rotation in the filling device by means of the shaft.
[0045] The shaft, or rather its central longitudinal axis, can be oriented along the axis of rotation. The central longitudinal axis of the shaft and the axis of rotation can be identical. The metering disc and the cone can each be arranged on the shaft. The cone can be arranged above the top surface of the metering disc with respect to the direction of gravity. The metering disc can have an opening, particularly a centrally arranged one, for receiving the shaft. The cone can have a conical opening, particularly a centrally arranged one, for receiving the shaft.
[0046] Regarding the advantages achievable with the filling device, reference is made to the corresponding explanations concerning the metering disc. The measures described in connection with the metering disc and / or those explained below can be used to further develop the filling device. The homogenization of the material can be further optimized by using the cone. According to a further development of the filling device, the cone can include a conical top surface. The conical top surface can be designed, at least in part, for depositing and / or contacting the material. The cone can have a conical bottom surface opposite the conical top surface. The conical top surface can include at least one conical blowing section. The conical blowing section can be designed to blow gas, in particular air or compressed air, into the material arranged on the conical top surface.
[0047] This allows the homogenization of the material to be further optimized.
[0048] The upper and / or lower cone surface can each be designed according to the above specifications to form the upper and / or lower surface of the metering disc. The upper cone surface can be designed analogously, and in particular identically, to the upper surface of the metering disc. The lower cone surface can be designed analogously, and in particular identically, to the lower surface of the metering disc. The cone blowing section of the cone can be designed according to the above specifications to form the blowing section of the metering disc. The cone blowing section of the cone can be designed analogously, and in particular identically, to the blowing section of the metering disc.
[0049] At least one conical cavity, and in particular several conical cavities, can be arranged between the upper and lower surfaces of the cone. The conical cavity can be designed according to the above descriptions to correspond to the cavity of the metering disc. The conical cavity of the cone can be designed analogously, and in particular identically, to the cavity of the metering disc. According to a further development of the filling device, the
[0050] The filling device may be configured to direct gas, in particular air or compressed air, through the shaft to the metering disc, in particular the blowing section. Alternatively or additionally, the filling device may be configured to direct gas, in particular air or compressed air, through the shaft to the cone, in particular the cone blowing section. For this purpose, the shaft may be at least partially hollow internally. The shaft may be designed as a hollow shaft. The shaft may have at least one channel for directing gas, in particular air or compressed air. Gas, in particular air or compressed air, may be introduced through the shaft from above with respect to gravity. Alternatively or additionally, it is conceivable that gas, in particular air or compressed air, may be introduced through the shaft from below with respect to gravity.
[0051] This allows for the simple implementation of gas routing through the shaft. In particular, it enables easy access to a gas or compressed air connection (using simple means). For example, a simple compressed air connection can be attached to the shaft.
[0052] According to a further development of the filling device, the filling device can comprise at least one, and in particular several, tamping plungers. The tamping plunger can be designed such that the material, which is arranged in particular on the upper side of the metering disc, can be metered into the metering opening by means of the tamping plunger. For this purpose, the tamping plunger can be designed to be movable along a direction of extension of the metering opening and / or along the direction of gravity.
[0053] This allows the material to be dosed into the dosing opening using simple means, thus providing a dose of the material.
[0054] According to a further development, the filling device can have at least one capsule holder for receiving at least one capsule half, and in particular several capsule holders for receiving capsule halves. The capsule holder can be arranged below the metering opening with respect to the direction of gravity. Alternatively or additionally, the metering opening can be arranged above the capsule holder with respect to the direction of gravity. For this purpose, the capsule holder and / or the metering disc (and thus the metering opening) can be movable or rotatable.
[0055] This allows the dose of material arranged in the dosing opening to be transferred to the capsule half located below the dosing opening using simple means. The dose of material arranged in the dosing opening can be ejected from the dosing opening by means of the tamping plunger and / or by means of an ejection plunger. The ejection plunger can be designed analogously to the tamping plunger.
[0056] The above problem is further solved by a method for dispensing, in particular powdered, material, preferably in capsules (e.g., hard capsules or hard gelatin capsules), by means of a dispensing disc according to the above embodiments or by means of a filling device according to the above embodiments with the features of claim 13. The method comprises the steps:
[0057] Arrange the material on the top of the metering disc and / or the top of the cone.
[0058] Injecting gas, in particular air or compressed air, into the material located on the top of the metering disc and / or on the cone's upper surface. The gas, in particular air or compressed air, is injected through the blowing section and / or the cone blowing section.
[0059] Regarding the advantages achievable with this method, reference is made to the relevant explanations concerning the metering disc or the filling device. The measures described in connection with the metering disc or the filling device and / or those explained below can be used to further develop the method.
[0060] According to a further development of the procedure, the procedure can include the following step:
[0061] Varying and / or adjusting the pressure, volume flow, humidity and / or temperature of the injected gas, especially air or compressed air.
[0062] This allows the fluidization level of the material to be adjusted or varied as desired using simple means. In particular, the residual moisture of the material to be dosed can be varied by adjusting the humidity level of the injected gas (e.g., by using a drying unit upstream). The material to be dosed can be cooled by adjusting the temperature of the injected gas, especially air or compressed air. This can be desirable if heat is generated by friction during the filling process. This heat can negatively affect the product (e.g., melting of particles) or filling accuracy (e.g., increased adhesion of material to surfaces). In these cases, the filling process often needs to be stopped and the filling equipment cleaned.
[0063] In this context, "adjusting" can refer to, for example, a one-time or repeated change (of pressure, volume flow, humidity, and / or temperature) before or after gassing or filling. "Variing" in this context can refer to, for example, a continuous or incremental change (of pressure, volume flow, humidity, and / or temperature) during gassing or filling.
[0064] According to a further development of the procedure, the procedure can include the following step:
[0065] Continuous injection of gas, especially air or compressed air, into the material that is located on the top of the metering disc and / or on the top of the cone.
[0066] Alternatively, gas, especially air or compressed air, can be injected into the material located on the top of the metering disc and / or on the cone's upper surface at time intervals. These time intervals can be varied and / or adjusted. This allows the fluidization level of the material to be easily adjusted or varied as desired.

The metering disc 10 can be configured such that gas, in particular air or compressed air, is first passed through the cavity 30 and then through the fabric element 22 and / or the blowing section 20. Thus, by introducing a gas or by applying overpressure to the cavity 30, gas, in particular air or compressed air, can be blown into the material 12 arranged on the upper surface 14.

[0091] It is also conceivable that the blowing opening 24 or blowing openings 24 can each be designed as a through-opening inclined towards the upper surface 14 of the metering disc 10. The blowing opening 24 or blowing openings 24 can each be inclined towards the direction of gravity 46 and / or towards the metering openings 18. The blowing opening 24 or blowing openings 24 can each have a cross-section that tapers towards the material 12 arranged on the upper surface 14.
