When thicker or sidewall has pit at long materials, can not obtain accurate measurement result, therefore, in each side of transfer path additional sensor is housed all.
In addition, also can use in the present invention a plurality of hard-wired sensors.These sensors are positioned at the horizontal transverse direction of transfer path top, need not movable sensor, just can be at measuring distance under the rigid condition, thus obtain more accurate measurement result.
Because method of the present invention can be measured the weight of any long materials that transmits continuously on conveyer, so this method can be as a kind of method of control product quantity and quality in the large-scale production process.
Fig. 1 and 2 has represented the motion of mobile one (or several) sensor, this sensor measurement from sensor to this long materials surface on the distance of a plurality of differences.
Fig. 3 and Fig. 4 are planimetric maps, have shown the transducer transversely track above long materials.
Fig. 5 is the side view of explanation another embodiment of the present invention, in this embodiment, above the long materials that transmits continuously a plurality of sensors that arrange is installed.
Fig. 6 is the planimetric map of the embodiment of Fig. 5, has shown that spatial separation is 1 two row measurement points, and at these some places, sensor measurement is by they distances to long materials.
Referring now to accompanying drawing a kind of embodiment of the present invention is described.
In Fig. 1, in the transmission of conveyer belt dough/pasta 2 is arranged, 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 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 ".
The light of being launched by sensor 3 and the reflected light that comes from the dough/pasta surface represent 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 consisted of 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 the return sectional area of the dough/pasta that stroke covers of sensor 3, 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, namely 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 X1, X
2... then their available following formulas represent:
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 l both sides moves back and forth vertically, measures from the sensor 4 and 5 distances to the lip-deep point of dough/pasta that are moving 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, the measurement result that is then obtained by top sensor 3 may be not enough accurate.Sensor 4 and 5 this moving back and forth by the 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, along horizontal transverse direction a plurality of sensors 6 that are arranged in rows be housed, each sensor 6 with adjacent sensor 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.Show a plurality of measurement points of this embodiment at Fig. 6 as seeing in the figure, measurement is carried out when the every displacement 1 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 more short, and measurement viscosity of the present invention is just more high.
As mentioned above, the present invention does not use any mechanical measurement, so, can avoid the various chance failures that caused by outside cause.When utilizing mechanical measuring means, for example, if scale is placed on below the conveyer belt, in order to measure the weight of the dough/pasta 2 that is transmitted 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 the dough/pasta weight of a given length with the method for quadraturing.According to the present invention, special device that need to be such as X ray protector or X ray knot sensitive element.
The measurement of the volume or weight of dough/pasta although 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.
