BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, in the present example, the powder and granular material quantitative supply / unloading device 1 is connected to, for example, a continuous mixer K that extrudes while kneading the additive into plasticized raw material rubber, and the additive is added to the continuous mixer K. It is used to continuously supply the granular material F which is a constant weight ratio.

The powdery / quantitative substance quantitative supply / unloading device 1 includes a supply device 2 for accommodating the powdery or granular material F, a carry-out device 3 for carrying out the powdery or granular material F from the supply device 2, and a supply device 2 of the supply device 2. A weighing device 5 for continuously weighing the total weight including the powder and granules F,
A control device 6 for controlling the carry-out capacity of the carry-out device 3 according to the amount of decrease in the powder or granular material F in the supply device 2 per unit time.

In the present embodiment, upstream of the supply device 2, there is a fixed amount distribution device 9 for intermittently supplying the powdery material F stored in the storage tank 7 to the supply device 2 at constant weight intervals. Will be placed.

The metering device 10 is connected to the metering device 10 for measuring the weight of the granules F charged from the feeder portion 7A at the lower end of the storage tank 7 and accumulated therein, and the granules F having a predetermined weight are connected. When is accumulated, the feeding from the feeder unit 7A is stopped via the control device 6. In the present example, the weighing device 10 measures the weight of the granular material F together with the quantitative distribution device 9 to calculate the input weight. Further, the quantitative distribution device 9 has an opening / closing tool 9A provided at the lower end thereof.
The predetermined weight (constant weight) of the stored powder or granular material F is supplied to the supply device 2 through the opening.

The supply device 2 has a downwardly tapered cone-shaped storage main portion 11 for storing a fixed weight of the granular material F supplied from the quantitative distribution device 9, and the stored granular material F is its own weight. Then, it is pushed forward by the stacking pressure and taken out downward from the take-out port 12A of the take-out side tubular portion 12 provided at the lower end of the main housing portion 11. A valve element 14 for temporarily stopping the supply of the granules F to the conveying device 3 can be provided at the upper end portion of the take-out side tubular portion 12 as required. Further, in order to prevent the contained powdery or granular material F from adhering to the inner wall surface and solidifying, the housing main portion 11 is provided with a solidification preventing tool 13 such as a so-called vibrator or knocker that vibrates the wall surface. Preferably, the storage tank 7 is also provided with the solidification preventing tool 13 for the same purpose.

Further, the carry-out device 3 is a so-called screw feeder in this example, and is a receiving side cylinder provided below the supply device 2 and having a receiving port 15A for receiving the powder or granular material F from the taking-out port 12A. It has a shape part 15 and a main transport part 16 which has a screw shaft 17 which is rotationally driven by the speed change motor M, which transfers the received granular material F and continuously carries it out from the carry-out port 3A. In the screw feeder, as well known, the carry-out capability is controlled by controlling the rotation of the screw shaft 17. In addition, various kinds of powder and granular material conveying devices such as a so-called electromagnetic feeder can be used as the conveying device 3. For example, in the case of an electromagnetic feeder, the conveying ability can be controlled by changing the amplitude by voltage.

The supply device 2 and the unloading device 3 are connected by a connecting means 19, and the takeout port 12 is connected.
The granular material F from A is introduced into the receiving port 15A without delay.

Here, what is required of the connecting means 19 is:
In order to accurately measure the weight of the supply device 2, the influence from the carry-out device 3 is eliminated as much as possible, and for that purpose, the take-out port 12A and the receiving port 15A are placed in a substantially non-contact state, and Even in the non-contact state, it is necessary to be able to continuously supply the granular material F corresponding to the carry-out amount from the carry-out device 3 sequentially from the receiving port 15A.

[0019] Therefore, for example, splicing means 19A, as shown enlarged in FIG. 2 (A), the output winding of the supply device 2
The side tubular portion 12 and the receiving side tubular portion 1 of the carry-out device 3
5 and. Note that [FIG. 2] to [FIG. 6], and
[FIG. 8] to [FIG. 9] are the same as those of the invention according to claim 1 of the present invention.
For the convenience of the order of explanation, the connecting method of things is used as a reference example.
(Hereinafter referred to as a reference example).

The outlet 12A is the tubular portion 1 on the outlet side.
2 and the receiving port 15A is defined as the upper end surface of the receiving side tubular portion 15.
The take-out port 12A and the receiving port 15A have the same shape or a shape in which the taking-out port 12A can be fitted into the receiving port 15A, and moreover, the cross-sectional area S1 of the taking-out port 12A is defined as the receiving port 1A.
The range is 30 to 100% of the cross-sectional area S2 of 5 A, and the outlet 12A is located in a range of a height lower than the receiving port 15A from a position 5 mm above the receiving port 15A. is doing. In FIG. 2A, the take-out port 12A has a shape that can be fitted into the receiving port 15A, and the take-out port 12A is lower than the receiving port 15A, so that the tubular portions 12 and 15 overlap each other. The case of having 20 and being loosely inserted is shown.

Here, the "shape in which the take-out port 12A can be fitted into the receiving port 15A" means that a part of the taking-out port 12A is a receiving port when viewed from above, as shown in FIG. 2 (B). The outlet 12A without protruding from 15A
Means the size and shape that can be included in the receiving port 15A.

In this example, the take-out port 12A and the receiving port 15
A has, for example, a circular similar shape and are arranged concentrically with each other, but if included in the receiving port 15A, the respective center positions may deviate as shown by the alternate long and short dash line. As shown in FIGS. 3, 4, 5 (A) and (B) showing other examples of the “fittable shape”, the take-out port 12A and the receiving port 15A are
The shape may be a polygonal shape other than a circular shape, such as a rectangle, or may be a non-similar shape such as one having a circular shape and the other having a polygonal shape.

In the splicing means 19A of such a reference example , as shown in FIG. 2 (A), the fluidity of the granular material F is worse than that of liquid or the like. The granular material F does not rise above the lower end surface thereof and does not flow out, so that the radial gap G between the tubular portions 12 and 15 is provided.
Even when 1 occurs, it is prevented from overcoming the tubular portion 15 and leaking from the gap G1. Moreover, at the lower end surface of the tubular portion 12, the pressure of the powder particles on the supply device side acting downward is balanced with the upward reaction force of the powder particles F on the transport device side. Body F and tubular part 1
The granular material F in 5 can be continuously continuous, and as a result, the amount of decrease in the surface of the granular material in the receiving side tubular portion 15 corresponding to the carry-out amount from the carry-out port 3A is reduced. The granular material F is
It is always supplied automatically by extrusion from the tubular portion 12.

From the viewpoint of leakage of the powder or granules F, it is preferable to provide the overlapping portion 20. At this time, the ratio S1 / S2 of the cross-sectional areas can be freely set within the range of 0.3 to 1.0. Can be set.

Further, as shown in FIG. 6, the outlet 12A
Is separated from the receiving port 15A and there is no overlapping portion 20, that is, when a vertical gap G2 is formed between the takeout port 12A and the receiving port 15A, the ratio S1
By setting / S2 to a smaller side and making the radial gap G1 large, leakage from the gaps G1 and G2 can be suppressed. That is, the granular material F from the outlet 12A
However, due to its low fluidity, it is balanced in a divergent state, and therefore leakage from the lowest point P over the tubular portion 15 is prevented.

When the gap G2 is larger than 5 mm,
Preventing leakage is difficult. When the ratio S1 / S2 is less than 0.3, the cross-sectional area S1 becomes too small, which may cause the supply device 2 to be insufficiently supplied with the granular material F, and conversely due to external vibration or the like. Leakage is likely to occur, and foreign matter may enter, which is not preferable. When the gap G2 occurs, it is preferable to provide a protective piece 21 that covers the gaps G1 and G2 and suppresses the entry of foreign matter at the lower end of the outlet 12A, as shown by the chain line in FIG.

In the connecting means 19A, which is a reference example,
Yet another example is shown in FIGS. FIGS. 8 and 9 show the case where the tubular portions 12 and 15 have the overlapping portion 20 and are loosely inserted. In FIG. 8, the tubular portion 12 is in the shape of a tapered cone, the lower end surface of which forms the outlet 12A, and the tubular portion 15 is in the shape of a downwardly spread cone. May be formed in a right cylindrical shape as shown in FIG. Further, in FIG. 9, the cylindrical portion 12
Has a straight cylindrical shape, and its lower end surface forms the outlet 12A. Further, the tubular portion 15 has a downwardly thin cone-shaped portion 15b on which the tubular portion 12 is loosely inserted, on the upper portion of the straight tubular barrel portion 15a, and the barrel portion 15a has substantially the same shape as the outlet 12A. Is formed in a cross-sectional shape. Further, in FIG. 10, the outlet 12A
And the receiving port 15A have the same shape, that is, the ratio S1 / S2 is 1.0. At this time, a sealing material 22 such as a flexible bellows for preventing leakage of the granular material F may be provided between the cylindrical portions 12 and 15 within a range that does not impair the measuring accuracy of the supply device 2.

It should be noted in order to further smooth the flow of the particulate material F in adoptive means 19A of the reference example, the tubular portion 15,
It is preferable to form a straight tube shape or a cone shape that spreads downward from the receiving port 15A without reducing the cross-sectional area, and when the tube-shaped portion 15 has a tapered cone portion 15b or a narrowed portion. It is preferable that the minimum sectional area is equal to or larger than the sectional area S1 of the outlet 12A.

As mentioned above, the connecting means 19 of the above-mentioned reference example.
By using (A), the cylindrical portions 12 and 15 are substantially in non-contact with each other, and the decrease amount of the powder or granules F corresponding to the carry-out amount from the carry-out port 3A is always continuously received. By being automatically supplied from 15A, it is possible to grasp the carry-out amount of the granular material F from the carry-out device 3 by the weight change of the supply device 2.

More specifically, the weighing device 5 is a weighing scale for continuously weighing the total weight of the supply device 2 held in a state of being floated from the unloading device 3 including the powdery or granular material F to be stored. As the rate of change of the measured value (measured weight) with respect to time, the reduction amount ΔW of the granular material F per unit time, that is, the carry-out amount can be grasped.

When the screw feeder or the like is operated with a constant discharge capacity (constant number of rotations), the discharge weight varies as shown in FIG. 7 (A) due to the influence of the bulk specific gravity of the granular material F. Becomes

Therefore, in the present invention, the controller 6 obtains the decrease amount ΔW of the powder or granular material F, and this decrease amount ΔW per unit time is calculated in advance per unit time ΔT of the powder or granular material F. The carry-out capacity of the carry-out device 3 is controlled so as to match the desired carry-out amount ΔW1 (shown by the broken line in FIG. 7A). That is, as shown in FIGS. 7A and 7B, when the actual decrease amount ΔW is larger than the desired carry-out amount ΔW1, the rotation speed of the screw shaft 17 is reduced in this example according to the ratio. The unloading capacity of the unloading device 3 is reduced, and conversely, when the desired unloading amount ΔW1 is smaller, the unloading capacity is increased. As a result, it is possible to greatly improve the accuracy of the transported weight.

Further, the control device 6 obtains the decrease amount ΔW from the measured value by the measuring device 5 as described above, and the decrease amount ΔW.
In addition to controlling the carry-out capacity of the carry-out device 3 in accordance with the above, in this example, when the total weight of the supply device 2 becomes less than or equal to the lower limit reference value,
The opening / closing tool 9A of the quantitative distribution device 9 is operated to supply the powdery material F having a constant weight to the supply device 2 and the feeder portion 7A is operated to store a constant weight from the storage tank 7 to the quantitative distribution device 9. To perform.

Here, since the total weight of the supply device 2 continuously changes, in order to correct the weight change due to the replenishment in the measured value, the constant amount distribution device 9 is used as in the present example, and the constant weight is fixed. Needs to be replenished. Also, the decrease amount Δ
In order to accurately measure W, it is necessary to transfer the powdery or granular material F using the splicing means 19 in a state where the feeding device 2 and the unloading device 3 are substantially in non-contact with each other. When the portions 12 and 15 are fixedly connected to each other, accurate measurement becomes difficult. In addition, the decrease amount Δ
Since W is measured, its accuracy can be greatly improved as compared with the measurement for each transport device 3 having a movable part such as a prime mover.

On the other hand, when the splicing means 19 of the above-mentioned reference example is used, depending on the type of the granular material F and the operating state of the apparatus, the granular material F is solidified on the inner wall surface of the receiving side tubular portion 15. It may turn into At this time, the cylindrical portion 1 is solidified.
Since the substantial cross-sectional area of 5 gradually decreases, the control device 6
In order to keep the carry-out amount from the carry-out device 3 constant, the driving amount of the carry device 3 is gradually increased, and the burden on the carry device 3 is greatly increased, which causes a failure such as overheating. When peeled off, a large amount of powder or granules may be carried out.

Therefore, in order to prevent the powdery or granular material F from solidifying in the receiving side tubular portion 15, it is desirable to provide the tubular portion 15 with a vibrator 25 (shown in FIG. 1). However, depending on the conditions such as the strength and direction of vibration by the vibrator 25, this vibration is transmitted to the take-out side tubular portion 12 via the powder or granular material F and interferes with accurate weight measurement of the supply device 2. Occurs.

Therefore, in order to prevent solidification of the powder and granules F and to measure the weight of the feeding device 2 with higher accuracy, the joining means 19 (B) of the second embodiment described below may be adopted. it can.

That is, the connecting means 19 according to the present invention.
11 (B), as shown in FIGS. 11 and 12, the receiving side tubular portion 15 is provided with the take-out port 1 below the take-out port 12A.
A swash plate 30 which is arranged apart from 2A and receives substantially the entire amount of the granular material F flowing down from the outlet 12A, and a back plate which forms a feeding gap 31 between a lower end 30E of the swash plate 30. 32 and 32.

The swash plate 30 is inclined so that the shortest distance L1 from the outlet 12A is 2 to 15 mm and has an angle α of 20 to 75 ° with respect to the vertical line. The case where 12A and the swash plate 30 are substantially parallel is illustrated.
In the case of non-parallel, the outlet 12A and the swash plate 30 are
It is preferable that the maximum distance between and is less than or equal to 2.0 times the shortest distance L1.

In the sending gap 31,
Distance L2 between the lower end 30E of the swash plate 30 and the back plate 32
Is 5 to 15 mm, and the gap 31 guides the granular material F to the root portion 17A of the screw shaft 17.

The connecting means 19 (B) of the second embodiment has an output portion 34 of a vibrator 34 on the side wall 33 of the receiving side tubular portion 15, in this example, the side wall 33 facing the back plate 32.
A is connected, so that at least the swash plate 30 is vibrated.

[0042] With this configuration, adoptive means 19 (B)
Since the swash plate 30 to which the powder F is fixed from the outlet 12A temporarily receives the powder F, the powder F can be continuously supplied at a constant pressure, and the pressure due to the rotation of the screw shaft 17 can be reduced. It is possible to reliably prevent the pulsation from being transmitted to the supply device 2 through the granular material F. Moreover, the reaction force acting from the swash plate 30 side to the supply device 2 side is suppressed as small as possible by the swash plate 30 having the angle α and the distance L1, and as a result, the weight measurement of the supply device 2 is adversely affected. Can be minimized.

Further, the vibrator 34 vibrates at least the swash plate 30, and in this example, the entire tubular portion 15, so that
The solidification of the powder F in the tubular portion 15 is surely prevented, while the swash plate 30 is adopted, whereby the vibration supply device 2 is provided.
The influence on can be largely eliminated. Further, since the swash plate 30 constantly guides the granular material F to the root portion 17A of the screw shaft 17, the flow of the granular material F is extremely stabilized, which is useful for improving the accuracy of conveying the granular material.

If the angle α exceeds 75 degrees, the swash plate 30 takes a long time to guide the granular material F received into the carry-out device 3, and the reaction force in the direction of pushing up the supply device 2 becomes strong. . Further, when the angle is less than 20 degrees and approaches the vertical direction, it becomes almost the same as in the case of the joining means 19A of the first embodiment, and it becomes difficult to prevent solidification of the granular material F and to measure the weight with high accuracy.

Further, when the distance L1 is less than 2 mm and the distance L2 is less than 5 mm, powdery granules F such as powdered sulfur which are easily solidified.
In the above, there is a possibility that a smooth flow may not be performed, such as clogging the outlet 12A and the gap 31. If the distance L1 and the distance L2 exceed 15 mm, the swash plate 30 does not function sufficiently, and the carry-out device 3 strongly influences the weight measurement with high accuracy.

FIG. 13 shows another form of the connecting means 19B of the present invention . In the figure, the splicing means 19B has upper and lower swash plates 30U and 30L having different inclination directions, and the upper swash plate 30U supports substantially the entire amount of the granular material F flowing down from the take-out port 12A and takes it out. Shortest distance L to mouth 12A
1 is set in the range of 2 to 15 mm. Also the swash plate 30 below
L has a distance L2 of 5 to 15 mm and is separated from the back plate 32, and forms a sending gap 31 for guiding the powdery or granular material F to the root portion 17A of the screw shaft 17. Upper and lower swash plate 3
The distance L3 between 0U and 30L is preferably in the range of 2 to 15 mm, which is equal to the shortest distance L1, and the inclination angle α of each swash plate 30U and 30L may be different in the range of 20 to 75 degrees. good.
