Abstract

PURPOSE: To enhance weighing accuracy by providing a magnetic system allowing the predetermined max. holding force to act on a rotor in the direction opposite to the rotary direction of the rotor. CONSTITUTION: The rotor 5 freely rotated around a horizontal rotary axis 4 is housed in a housing 1 and a plurality of holding means allowing the predetermined max. holding force to act on the rotor 5 in the direction reverse to the rotary direction of the rotor 5 are provided. This holding means are constituted of four permanent magnets 20 attached to the plate 19 fixed to the housing 1 at a right angle to the rotary axis of the rotor 5 and four permanent magnets 21 fixed to the disc 17 of the rotor 5. When a substance to be weighed is supplied into the small chambers 10 of an impeller 6 from a supply port 2, the rotor 5 is ready to rotate in the direction shown by an arrow 18 but this rotation is prevented by the holding forces of the magnets 20, 21. However, if the supply of the substance is continued, the wt. of the substance exceeds the holding forces acting on the rotor 5 at a certain point of time and the rotor 5 is rotated. As mentioned above, the rotor 5 is rotated only by the wt. of the substance in the small chambers 10 and weighing accuracy can be enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a flow metering device for free-flowing or dispersible solids, in particular granules or powders.

[Prior Art] Powder flow metering devices are well known, one type of which operates by equilibrium action. A pan on one counterbalancing arm attached to the device is tilted in a vertical plane, and the pan is divided into adjacent compartments by a partition. The position at which the pan tilts is below the center of gravity of the pan on the balance arm. A weight is attached to the other balance arm. During weighing, one of the small chambers is filled with the substance to be weighed. In order to prevent the pan from tilting due to the substance to be measured filled in the small chamber, a holding member is fixed to the top of the pan, thereby keeping the partition stationary during the filling. When the small chamber of the pan is filled with the substance to be weighed excessively, the balance arm on the pan side tilts, causing the pan to descend and not be held by the holding member.

As a result, the van tilts towards the filled side, the other chambers come to rest under the material being fed, and the filled chambers become empty. The balancing arm then rotates back under the influence of the weight of the other balancing arm, the pan rises again and the chamber is held still by the holding member, but towards the other side. At this time, other chambers are filled and the cycle repeats. The filling amount of each chamber can be set by a weight on the other balancing arm.

[Problem M to be solved by the invention] The drawbacks of the above conventional system are that there are many mechanical transmissions IaNIt, which requires precision in setting the weight weight, and that the moving parts are significantly contaminated in a dusty environment. etc. Also, although electronic weighing systems exist, they are very expensive. The object of the invention is, on the one hand, to obtain a high degree of accuracy and not to degrade said accuracy even in very dusty environments, and on the other hand to obtain a simple and relatively inexpensive free-flowing or dispersible solid material. In particular, the object of the present invention is to provide a flow metering device for granular or powdered materials. [Means for Solving the Problems] In order to solve the above problems, the present invention includes a rotor that is substantially freely rotatable around a horizontally fixed rotation axis, and at least one rotor that is adjacent to each other when viewed from the rotation direction. two chambers, means for supplying the object to be weighed into the chamber of the rotor, means for discharging the weighed object from the chamber of the rotor, and maintaining a preset maximum value; and a holding means for applying force to the rotor in a direction opposite to the rotation of the rotor. [Operation: Since the device of the present invention does not substantially include any movable parts other than the rotor, and the rotor only rotates around its axis, the measurement accuracy may be affected by contamination of these movable parts. There is no. According to the device of the present invention, the weight of the substance to be weighed that is introduced into the small chamber at one time is determined by the maximum holding force exerted by the holding means on the rotor, and the holding force is adjustable. Also, because it is stable over time, extremely high weighing accuracy can be obtained. moreover,
Since the structure of the device of the present invention is simple, it can be manufactured at low cost. The holding means fixes at least one permanent magnet at a position relative to the rotational axis of the rotor or on the rotor, and further maintains another magnetic or magnetizable member at a predetermined distance from the permanent magnet. It is preferable that the magnetic system is attached on the rotor or at a position relative to the rotation axis of the rotor to exert the holding force. The magnitude of this holding force is determined by the magnetic force exerted on other members on the side of the at least one permanent magnet. The maximum value of the holding force is determined by the maximum value of the magnetic force exerted on other members on the side of the at least one permanent magnet. Since there is no contact between the at least one permanent magnet and other magnetic or magnetizable members, no friction or wear occurs, and accuracy does not deteriorate.

The magnetic field of modern permanent magnets is highly stabilized, and with such magnets the magnetic force is also extremely stable over time.

[Embodiment] The apparatus according to the embodiment of the present invention shown in FIGS. 1 to 4 includes a housing 1 having a supply port 2 for the substance to be measured at the top and a discharge port 3 for the substance to be measured at the bottom. The housing 1 is closed all around, except for the supply port 2 and the discharge port 3 for the substance to be measured. A rotor 5 that freely rotates around a substantially horizontal axis of rotation 4 is housed inside the housing 1 . The rotor 5 includes an impeller 6 that extends substantially diametrically from the rotating shaft 4 and has four blades 7 parallel to the rotating shaft 4. The blades 7 are connected to end plates 8 and 9 perpendicular to the rotation axis 4 that are in contact with both ends of the impeller 6, and are connected to the four small rooms 1.
Form 0. The vanes 7 are positioned at an angle of 90° to each other such that each of the small portions M10 covers a sector of 90°. The impeller 6 is mounted in the housing 1 via a shaft 11, which is connected to the front and rear walls l of the housing 1.
It is supported by bearings 4 and 15, l2 and l3. The shaft 11 projects from the front wall l4 of the housing l via a bearing 13.

A disk 1 is attached to the shaft end 6 of the shaft l1 protruding from the housing 1.
7 is installed. As will be described later, the disk 17 is used for positioning the rotor 5, particularly for positioning the impeller 6 of the rotor 5 in the rotational direction.

The above device is equipped with a plurality of holding means that apply a predetermined maximum holding force to the rotor 5 in a direction opposite to the rotation of the rotor 5. The direction of rotation of the rotor 5 is indicated by an arrow 18. The plurality of holding means are the housing 1
four first permanent magnets 20 mounted perpendicularly to the rotational axis of the rotor 5 on a plate 19 fixed to the rotor 5; and four second permanent magnets 21 fixed on the disk 17 of the rotor 5. It is equipped with The first permanent magnet 20 and the second permanent magnet 21 are respectively located on concentric circles having different diameters with respect to the rotation axis of the rotor 5.

The diameter of each concentric circle in which the first permanent magnet 20 and the second permanent magnet 21 are located is such that the second permanent magnet 21 is the same as the first permanent magnet 21.
It is set so that it can move closely along. Each first permanent magnet 20, like the second permanent magnet 21, is placed at a distance of 90' from each other. The rotation of the rotor 5 is stopped by the holding force between the respective permanent magnets. The magnitude of the holding force is determined by the interaction force between each first permanent magnet 20 and second permanent magnet 21. The interaction force described above depends on various factors such as the strength of magnetization of each permanent magnet and the spacing between the first and second permanent magnets.

The position of the disk 17 with the second permanent magnet 21 in relation to the position of the impeller 6 in the direction of rotation of the rotor 5 is as follows. As shown in FIG. 2, in the four fixed positions of the rotor 5 determined by the permanent magnets 20 and 21, one of the chambers 10 of the impeller 6 is located below the supply port 2;
A guide plate 2 in which one outer edge of an upwardly extending blade 7 of an impeller 6 in the rotational direction of the rotor 5 is attached to the supply port 2
Comes to the front of 2. The first and second permanent magnets are preferably attached so that they repel each other. However, it is also possible to attach the first and second permanent magnets so that they attract each other. Furthermore, one of the first and second permanent magnets can be replaced with iron or other materials that are attracted to the permanent magnet. As shown in FIG. 3, as the rotor 5 rotates, a fixed electric switch 24 is actuated by four cams 23 attached to the disc 17.
Four revolutions are detected and recorded. The device of the present invention described above is equipped with means for locking the rotation of the rotor 5 at a specific position. These locking means include a pin 25 that is movable back and forth in the direction of the rotational axis of the rotor 5, and the pin 25 engages with four holes 26 on the disc 17 in the locked position. The pin 25 is moved back and forth by an electromagnet attached to the plate 19. Disk 17, plate 19, permanent magnets 20 and 2↓, electric switch 24, and electromagnet 27
is housed in a cabinet 28 outside the housing 1 to protect it from dust. In order to prevent dust from the bearings 12 and 13 of the housing 1, particularly the bearing 13, from entering the housing 1, the bearings 12 and 13 are of a dust-proof type.

Next, the operation of the apparatus of the present invention will be explained.

In the position of the impeller 6 shown in FIG.
supplied within. The above substance comes to rest on the wing extending to the left in FIG. Due to the weight of the above material, the rotor 5
attempts to rotate counterclockwise, that is, in the direction of arrow 18. However, since this rotation is prevented by the holding force between the first and second permanent magnets, the impeller 6 remains at the position shown in FIG. 2. As the supply of the substance continues, at a certain point, the torque acting on the rotor 5 due to the weight of the substance in the small chamber 10 at the bottom of the supply port 2 exceeds the holding force by the permanent magnets. Permanent magnets 20 and 21 can no longer hold rotor 5 and rotate in the direction of arrow 18. It is clear that the weight of the material present in the chamber 10 at this time is closely related to the holding power of the permanent magnet. When the rotor 5 begins to rotate, the pin 25 is placed in the lock position by the electromagnet 27, and after the rotor 5 has rotated 90'', the pin 25 falls into the hole 26 of the disk 17, stopping the rotor 5. During rotation, one of the cams 23 passes through the electrical switch 24 and actuates it.As a result, the electrical switch 24 generates a recordable pulsed signal.

When the impeller 6 rotates 90'', the substance filled in the small chamber passes through the discharge port 3 in the direction shown by the arrow 30 and falls.At the same time, the next small chamber 10 stops at the bottom of the supply port 2. , where the next substance to be weighed can be filled.

At the same time that the rotor 5 is stopped at the position shown in FIG. 2 by the pin 25, the pin 25 is removed by the electromagnet 27, and the rotor 5 is
That is, the blades 6 can again freely rotate. The device thus enters the next weighing cycle.

Since the rotational force of the rotor 5 is generated solely by the weight of the substance within the chamber 10, the accuracy of the weighing is extremely accurate. Since the rotor 5 is balanced in principle, the rotor 5 does not affect the above measurement. Only the net weight of the material is measured, and there is no extra weight as in conventional devices. Even if the balance of the rotor 5 is slightly lost due to the adhesion of substances, the effect will be completely removed after the rotor 5 rotates once.

In addition, if the permanent magnets 20 and 21 are installed so that they repel each other, when the inside of the small room 10 is filled to the maximum and the permanent magnet 21 on the disk 17 passes through the small room 17, the permanent magnet 21 Since the repulsive force between the two angles is added, the rotor 5 receives the extra force and rotates very quickly. This fast rotation of the rotor 5 is advantageous for the accuracy of weighing. When the rotor 5 rotates forward, the blades projecting upward accurately oppose the guide plate 22 of the supply port 2, so that the measurement accuracy is further improved.

A curved partition plate 31 is provided inside the housing 1 . When the impeller 6 tries to rotate first due to the weight of the substance in the small chamber filled, the center of gravity of the substance in the small chamber does not change due to the partition plate 31, so the torque exerted by the substance on the rotor 5 is also reduced. It also stops changing. The partition plate 31 extends parallel to the rotating shaft 4 and is connected to the housing 1 by a pivot shaft 32 near the supply port 2. A pin 33 with play protruding from the housing 1 is provided at the bottom of the partition plate 31. , a stopper 34 is provided on the outside of the housing 1. Due to its own weight, the partition plate 3l tends to move in the direction of the rotation axis 4 of the rotor 5. This movement is limited by the stopper 34 and rests against the wall 35 of the housing 1. The partition plate 31 can freely move in the direction of the rotation axis 4 of the rotor 5 to a position where it stops against the wall 35 in the housing 1. At the position where the stopper 34 stops against the wall 35 of the housing 1, the surface of the partition plate 31 is just outside the cylindrical surface formed by the outermost periphery 36 of the blade 7. This prevents the blades 7 from hitting the partition plate 31. Since the substance in the small room 10 hits the partition plate 3l and comes to rest,
The shape of the outer boundary surface of the substance in the small chamber 10 is substantially constant, and the center of gravity of the substance in the housing 10 corresponding to the rotation of the rotor 5 is always located at the same distance from the rotor 5.

In order to prevent the impeller 6 from rotating in the direction opposite to the arrow 18 when the impeller 6 rotates forward and is released from the pin 25, the outer end of the blade 7 forms a cylinder. A flexible reverse prevention piece 37 that protrudes upward from the housing 1
located within. Reverse blocking piece 37 when rotor 5 rotates forward.
Although the force acting on the impeller 6 is small, when the impeller 6 rotates in the opposite direction, the blades 7 hit the free end of the reverse blocking piece 37 and stop, so the impeller 6 is stopped by the reverse blocking piece 37.

FIG. 5 is a diagram showing a magnetic system that holds the rotor 5, and includes four permanent magnets 20 fixed to the rotor 5 and four permanent magnets 21 attached to the rotor 5. The holding force is always generated by the four pairs of permanent magnets. By this method, the holding force is extremely stable, and furthermore, the holding force can be easily and precisely set by adjusting the position of one of the permanent magnets 20.

FIG. 6 is a diagram explaining the action of the two mutually repelling magnets 20 and 21 of the magnetic system shown in FIG. When the rotor 5 is rotating in the direction of the arrow 18, the rotor 5 is held at the position shown by the solid line by the repulsive force of the magnets 20 and 21. This is where the maximum repulsive force acts. When the weight of the substance in the small chamber of the rotor 5 exceeds this repulsive force, the rotor 5 further rotates in the direction of arrow l8.

The magnet 21 moves to the other end of the magnet 20 indicated by the dotted line. At this time, as a result of the repulsive force between the magnets 20 and 21 being applied in the direction of arrow l8, the rotor 5 is accelerated and further rotates.

Calibration of the metering device described above is extremely simple. During the above calibration,
All parts are set in the same way. After rotating the rotor 5 at a predetermined number of revolutions (for example, 10 revolutions), the user supplies and weighs the substance to be measured. As a result, the rotor 5
When rotates first, the weight value of the above substance in one of the chambers is obtained. This weight value is input into, for example, a computer and processed.

FIG. 7 is a diagram illustrating another embodiment of the present invention. Here the rotor can be tilted about an axis 41 and the partition 4
It has a receiving part 42 with 3. In this way, two small rooms 44 and 45 are formed. A supply port 46 is provided at the top of the receiving portion. Outlets 47 and 48 are provided at the bottom of the small rooms 44 and 45. The receiving part 42 can in principle assume two positions, namely a position tilted to the right and a position tilted to the left. When the receptacle 42 is tilted to the left, the chamber 44 can be filled with metered substance.

On the bottom side, the outlet 47 is closed by a plate 49 which is hinged to the receptacle 42 . The weight of the substance within the chamber 44 tends to cause the receiving portion 42 to tilt to the right. This tilting force is lth
A magnet substantially similar to the embodiment of the invention shown in FIGS. Small room 4 of receiving part 42
When a torque is generated by the substance in 4, the receptacle 42 tilts to the right, so that the outlet 47 opens and the chamber 45 comes to rest under the supply opening 46. Further, the discharge port 48 is closed by a plate 50. During the filling period of the chamber 45 in this position, tilting to the left is likewise prevented by the holding force of the magnet.

[Effects of the Invention] The above-described measuring device for flowing granular material or powder according to the present invention has the features summarized below. Extremely high weighing accuracy can be obtained for the following reasons. a) Since there is no transmission mechanism, the measurement accuracy is not affected by the frictional force of such a transmission mechanism.

b) Since the device of the invention does not contain parts that slide relative to each other, there is only rotation of a rotating rotor supported on a rotating shaft;
The effect of frictional force (bearing friction) can be ignored. c) In principle, the rotor is in a well-balanced state, so only the product can be weighed and is not affected by the weight of the rotor (there is no tare weight in conventional devices). Any unbalance effects, such as the effects of substances adhering to the rotor, are completely eliminated after 360° rotation of the rotor. d) A holding force can be applied to the rotor without contact by using a magnetic system.

e) Using mutually repelling magnets (N-N or S-S), after the filling amount in one small chamber reaches its maximum value due to the repulsive force, quickly rotate the rotor beyond that point. be able to. f) When the filling amount in one small room reaches the maximum value, the center of gravity of the filling material can be accurately set (based on the adoption of partition plates). The value of the measurement error achieved by the present invention is approximately 0.1%. The above-mentioned error of the conventional device using a balance arm is approximately 2%.

The device of the present invention measures! Because the I-structure is housed in a dust-tight or water-proof enclosure, it can be used in extremely dusty environments. Weighing accuracy is not affected by dust.

The device of the present invention has a simple structure and is inexpensive.
