Description
Technical field
The present invention relates to a kind of apparatus and method that are used for dosage powdery product, especially food.
Background technology
Dosage loose, an important goal is during powdery product, as far as possible accurately dosage is treated the weight of hope of the product of dosage.Especially the deficiency that when food, must definitely avoid packing owing to legal provisions is filled.Therefore when dosage, adjust few overweightly usually, fill so that avoid not enough safely.Yet excessive filling means unnecessary loss for packaging company.By the known a kind of dosing mechanism that is used for powdery product of DE 197 43 057A1, wherein use flexible dosage adaptor union and deformation-sensor, deformation-sensor detects the expansion of dosage adaptor union.Control unit is controlled total angle of rotation of dosage worm screw then based on detected expansion, so that confirm weighting material quantity.Yet this device is relatively bothersome and have certain inexactness.
Summary of the invention
Has structure advantage very simple and with low cost according to the device that is used for the dosage powdery product of the present invention with respect to this.In addition by can very accurately confirming loading according to device of the present invention, thus not for another example the prior art that kind need excessive filling.This realizes according to the present invention in the following manner: this device comprises dosing mechanism, is used to control the control unit of said dosing mechanism and is used to detect electromagnetic at least one sensor that wherein, sensor is confirmed the density of powdery product.Control unit is controlled dosing mechanism based on the density value of preferably repeatedly being obtained by sensor, can realize point-device filling thus.
Dependent claims illustrates preferred development configuration of the present invention.
Particularly preferably, dosing mechanism comprises the Worm type dispenser.Can carry out point-device dosage by the Worm type dispenser.
Further preferably, sensor is ultra-wide band sensor or microwave remote sensor.Can realize thus that cost is cheap especially and the sensor of precise results is provided.
According to the preferred design plan of another kind of the present invention, this device comprises the first sensor and second sensor, and first sensor is arranged on the entry zone of dosing mechanism, and second sensor is arranged near the exit region of dosing mechanism.Redundant density measurement can be on dosing mechanism, realized thus, more accurate dosage can be realized thus.
This device also comprises hopper, and this hopper is arranged on the dosing mechanism front with storage powder shape product.First sensor is arranged on the transitional region between hopper and the dosing mechanism and second sensor is arranged on the end of dosing mechanism at this, promptly is arranged near the discharging area that powdery product discharges from dosing mechanism.
Also preferably, this device comprises the 3rd sensor, and the 3rd sensor is being arranged on the dosing mechanism between the first sensor and second sensor on the said device delivery direction.Can further improve the precision of dosage thus.
The invention still further relates to a kind of method that is used for the dosage powdery product, wherein, before the dosage process and/or during by the density that is used to detect electromagnetic sensor measurement powdery product.According to the density value of obtaining powdery product is carried out dosage then, can realize the dosage precision of improving thus.Preferably carry out dosage at this by the Worm type dispenser, wherein, can be before the Worm type dispenser and/or in the Worm type dispenser, obtain the density of powdery product.Control unit based on density value control dosing mechanism is preferably controlled rotating quantity and/or the revolution of Worm type dispenser and/or the time of run of Worm type dispenser of Worm type dispenser at this.Abnormal cost can use ultra-wide band sensor or microwave remote sensor as sensor at this cheaply.
The invention still further relates to the application that microwave is used for confirming the density of powdery product to be filled, so that can realize accurate dosage to powdery product.
The present invention particularly preferably uses at the pad device of the food that is used for scattering, for example coffee powder, milk powder, flour, sugar, salt etc. at this.
Description of drawings
Next with reference to accompanying drawing the preferred embodiment of the present invention will be described in detail.In the accompanying drawings:
Fig. 1 illustrates the schematic cross sectional views according to the dosing mechanism of the preferred embodiment of the present invention.
The specific embodiment
Fig. 1 illustrates the schematic cross sectional views of the device 1 that is used for dosage powdery product 2.Powdery product 2 is stored in the hopper 3, and wherein, hopper 3 is arranged on dosing mechanism 4 tops, and this dosing mechanism is constructed to the Worm type dispenser.Dosing mechanism 4 comprises conveying worm 5 at this, and this conveying worm is arranged in the tubular shell 6.Conveying worm 5 drives by actuating device 7 at this.
Device 1 also comprises first sensor 11, second sensor 12 and the 3rd sensor 13, and they are constructed to microwave remote sensor.Microwave remote sensor is at this launched microwave and detect the microwave through reflection again.Three sensors 11,12,13 are connected with control unit 8 at this, this control unit accessory drive 7.
As shown in Figure 1, first sensor 11 is arranged on the transitional region between hopper 3 and the dosing mechanism 4 at this.Second sensor 12 is arranged on the end of dosing mechanism 4 and the 3rd sensor 13 is being arranged between first and second sensors on the throughput direction of conveying worm 5. Sensor 11,12,13 is transmitted into microwave in the conveyor zones of conveying worm 5 at this, and the powdery product that these microwaves are positioned in the conveyor zones is reflected according to the density of powdery product.Look the density of powdery product and decide, for the value that the microwave through reflection obtains confirming, these values of confirming can be used as the yardstick of the density of powdery product and consider.Control unit 8 designs at this in this wise, makes control unit based on the actuating device 7 by sensor 11,12,13 detected values control dosing mechanisms 4.Density preferably repeatedly is determined during filling process at this, so that guarantee the accurate as far as possible dosage of powdery product 2.Arrow A representes that powdery product 2 for example is discharged in the packing in Fig. 1.
Because conveying worm 5 is processed by conductive material, especially corrosion-resistant steel usually, so conveying worm 5 has been contributed a signal numerical value equally during through the signal detection of sensor.Yet this signal numerical value is owing to it periodically can be come out by the calculated signals of reality simply.This for example can not carry out when worm screw is filled before dosage begins yet.
Therefore, the present invention can realize the more accurate dosage to powdery product 2.For example when the quantity of dosage is the 500g coffee powder, adjust for safety in the prior art+the excessive filling of 2g, by can be with overweight being adjusted to+0.5g according to the sensing device on dosing mechanism of the present invention.Obtain 75% overweight saving of every packing thus, obtain significant cost for packaging company thus and reduce.
