Referring now to accompanying drawing a kind of embodiment of the present invention is described.
In Fig. 1, transmitting on the conveyer belt has dough/pasta 2, and sensor 3 is positioned at its top.Sensor 3 moves around along horizontal transverse direction above dough/pasta 2, and its moving direction is by arrow m and m ' expression.Sensor 3 emission bright dippings also detect its reflected light from the body surface part of each measurement point, and adjacent two measurement points are determined apart from m at a distance of one ".
Light of being launched by sensor 3 and the reflected light that comes from the dough/pasta surface are represented with vertical curve H.Sensor 3 is made up of a light-emitting component and a reflected light sensitive element, and these two elements have constituted the sensor as an overall work.
The light that is sent by light-emitting component has been subjected to reflection on the dough/pasta surface, by the reflected light detecting element this reflected light is detected.This reflected light comprises corresponding to the range information of sensor 3 to the distance on dough/pasta surface, and is converted into electric signal.
When sensor 3 moves around, the electric signal in each measurement point is sent to computing machine above the dough/pasta 2 that just is being transported.Computing machine calculates the dough/pasta height of each measurement point according to the signal of receiving, and " the dough/pasta height value multiplies each other therewith, and obtains getting very thin dough/pasta sectional area with distance value m.When sensor 3 has been finished it and crossed over transverse movement by scope shown in the arrow m, this area is carried out integration.Thereby obtain a sectional area, this sectional area is called as " sectional area A ".Computing machine multiplies each other with the value of a predetermined length l and sectional area A, and length l is corresponding to the transmitting range of dough/pasta in the unit interval, thereby obtain the volume of this dough/pasta relative section, multiply each other with the proportion P of dough/pasta and its volume then, thereby obtain the weight of the dough/pasta of unit length l.Then, sensor 3 moves to shown in arrow m ' on the original position, measures distance with method same as described above simultaneously.Therefore, just obtain by sensor 3 return stroke the sectional area of topped dough/pasta, this sectional area is called " sectional area B ".Multiply each other with l and cross-sectional area B then, multiply each other with P again, promptly obtain the weight of the dough/pasta part of next length l.If the weight of the each several part dough/pasta that records is expressed as X
1, X
2... then their available following formulas are represented:
X
1＝A×l×P，X
2＝B×l×P
If dough/pasta is thicker, the sensor 4 and 5 that is contained in conveyer 1 both sides moves back and forth vertically, measures sensor 4 and 5 distances of seeing from moving to the lip-deep point of dough/pasta from horizontal direction, replenishes range information with the information of each side of dough/pasta thus.So need this method, be because if dough/pasta is very high, then the measurement result that is obtained by top sensor 3 may be accurate inadequately. Sensor 4 and 5 this moving back and forth by arrow n among Fig. 2 and n ' expression.
The transverse movement of the sensor 3 above in Fig. 3 and 4, further specifying.In these figure, dough/pasta 2 is transmitted by conveyer belt 1, and the track of sensor 3 is represented by line segment J and K.In Fig. 3, sensor 3 is more faster than the situation of Fig. 4 with respect to the translational speed of dough/pasta, and is longer in the residence time of each side of dough/pasta.Therefore, this residence time is basically corresponding to distance l.The track of sensor 3 is to be formed by moving back and forth of it, and it is from an a, continuously by some b, c, d, e ..., the point on line segment J and the K is the point that sensor is measured.Track may be as shown in Figure 4 very in short-term lower and residence time when the relative velocity of sensor 3.In this case, must adjust accordingly measurement.
In Fig. 5, shown another embodiment of the present invention, wherein above conveyer belt 1, a plurality of sensors 6 that are arranged in rows be housed along horizontal transverse direction, each sensor 6 with adjacent sensor all at a distance of a short distance m " '.These a plurality of sensors are measuring distance simultaneously, and therefore, this device can obtain more accurate measurement result.The a plurality of measurement points that show this embodiment at Fig. 6 are as seeing in the figure, and measurement is carried out when the every displacement l of dough/pasta, and computing machine calculates the weight of dough/pasta with the similar approach described in the embodiment of front then.In two embodiments, length l is short more, and measurement viscosity of the present invention is just high more.
As mentioned above, the present invention does not use any mechanical measurement.So, can avoid the various chance failures that cause by outside cause.When utilizing mechanical measuring means, for example, if scale is placed on below the conveyer belt, so that measure the weight of the dough/pasta 2 that transmits by belt with mechanical means, the stretching of belt tends to disturb the weight measurement of dough/pasta 2 so, so just can not obtain accurate weight measurement.According to the present invention, the cross-sectional area of the dough/pasta that can continuous coverage transmitting continuously with sensor, thereby can continuous coverage each volume and weight of fraction dough/pasta very, therefore be easy to calculate a dough/pasta weight of giving specified length with the method for quadraturing.According to the present invention, need be such as the special device X ray protector or the X ray sensitive element.
The measurement of the volume or weight of dough/pasta though embodiment of the present invention are mainly touched upon, the present invention never are only limited to dough/pasta measures, and it also can be used for measuring plastic material, viscoelastic material and long rigid material.
