Abstract

PROBLEM TO BE SOLVED: To simplify the granular substances discharge control operation by making a casing rotatable in the peripheral direction and controlling the discharge position and discharge quantity of granular substances by moving a discharge port in an optional direction. SOLUTION: In a screw conveyor 1, the granular substances supplied from a granular substance input port 5 are carried by a carrying screw, which is rotatively driven by a screw drive device 6. In the carrying process, the granular substances are discharged downward from a discharge port 4 opening toward a casing 2, filling a container 8 and being piled up in the container 8. The casing 2 and the discharge port 4 are slowly rotated by a casing driving device 7. The substances flow out from the discharge port 4 the most at the section facing downward and the quantity of granular substances flow out becomes smaller as advancing to both the right and left sides, and the granular substances are scarcely discharged from the upper section above the right and left sides. When the quantity of the granular substances piled up in the container 8 gradually becomes large enough to reach the position of a sensor 9, the detected value is sent to a personal computer.

As described above, providing a required number of shutters and shutter driving mechanisms for opening and closing the shutters at arbitrary positions on the conveyor casing increases the complexity of the mechanism and increases the cost. Also, there is a problem that the operation of the shutter drive mechanism is troublesome.

With the above arrangement, the apparatus for conveying and distributing particulate matter according to the present invention performs the following functions. . By enabling the casing to rotate in the circumferential direction and moving the discharge port in any direction to control the discharge position and discharge amount of the granular material, the discharge / fall position of the granular material can be arbitrarily moved.

[0011]

Embodiments of the present invention will be specifically described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a screw conveyor. The screw conveyor 1 is provided with a conveying screw 3 driven and rotated in a cylindrical casing 2, and is formed of a continuous spiral slit on the peripheral surface of the casing 2. In the process of forming the outlet 4 and transporting the granular material supplied from the granular material inlet 5 provided at one end of the transport screw 3 to the other end, the granular material is discharged from the outlet 4 and distributed. It is like that.

The conveying screw 3 is driven to rotate by a screw driving device 6 provided at one end of the casing 2.
The casing 2 and the discharge port 4 are driven to rotate in the circumferential direction by a casing driving device 7 provided on the other end side of the casing 2, and the discharge position and discharge of the particulate matter are caused by moving the discharge port 4 in an arbitrary direction. The amount is controlled. The discharge port 4 is formed by continuously forming a helical slit in the casing 2 so that the outer circumference from the start end to the end in the longitudinal direction makes substantially one rotation.

On the lower side of the screw conveyor 1,
As shown in FIG. 2, a container 8 for receiving the granular material discharged from the discharge port 4 and falling is disposed. A sensor 9 is provided for detecting the amount of the particulate matter discharged from the casing 9.
, The casing 2 is rotated to control the discharge position and discharge amount of the particulate matter. The rotation control command of the casing 2 based on the detection value of the sensor 9 is issued by a personal computer (not shown).

Next, the operation of the screw conveyor 1 configured as described above will be described. The granular material supplied from the granular material input port 5 is transported by the transport screw 3 that is rotated and driven by the screw driving device 6, and is discharged downward from the discharge port 4 opened in the casing 2 during the transport process. Is filled and deposited in the container 8. The casing 2 and the outlet 4 are slowly rotated in one direction by a casing driving device 7. Most of the particulate matter is discharged from the discharge port 4 at the portion where the discharge port 4 faces downward, and gradually decreases toward the left and right sides, and is hardly discharged from the left and right sides at the upper portion.

When the amount of the particulate matter charged and deposited in the container 8 gradually increases and reaches the position of the sensor 9, the detected value is sent to the personal computer, and a rotation control command is issued to the casing driving device 7. Then, no particulate matter is discharged to the sensor 9 part. Then, filling the container 8
The operation of the screw conveyor 1 is stopped when the amount of the accumulated particulate matter becomes constant as a whole. The operation stop command of the screw conveyor 1 is also automatically stopped by issuing an operation stop command of the screw conveyor 1 from the personal computer when all the sensors 9 detect the filling of the granular material.

FIG. 3 shows another embodiment of the present invention. In this embodiment, in place of the continuous spiral discharge port 4, an intermittent discharge port 10 is formed on the same spiral locus by changing the phase in the circumferential direction intermittently. A partition 8a is arranged in the container 8 at intervals to divide the container into a large number of containers, and the rest has the same configuration as in the above embodiment. The particulate matter discharged from each intermittent discharge port 10 is discharged into each of the containers 8 partitioned by the partition 8a, and is filled and deposited. Further, a sensor 9 is provided at an upper position of each container 8 partitioned by the partition 8a.

In the screw conveyor 1 of another embodiment configured as described above, the granular material transported by the transport screw 3 is discharged into each container 8 partitioned by the partition 8a. Filled and deposited. Therefore, a desired amount of granular material can be filled and deposited in each of the containers 8 partitioned by the partition 8a.

[0018]

As described above, according to the apparatus for transporting and distributing particulate matter of the present invention, the following effects can be obtained.

[0019] The casing can be rotated in the circumferential direction,
Since the discharge position and discharge amount of the particulate matter are controlled by moving the discharge port in an arbitrary direction, it is possible to arbitrarily move the discharge / fall position of the particulate matter.
In addition, the casing can be rotated in the circumferential direction with one power to move the discharge / drop position of the particulate matter arbitrarily.
The mechanism can be simplified and the device can be provided at low cost. Further, the operation of controlling the discharge of the particulate matter can be easily performed.

[0020] Since the discharge port is arranged continuously or intermittently in the circumferential direction with respect to the peripheral surface of the casing, the uniform phase is maintained in the transport direction of the transport screw. Can be discharged and dropped, and the container can be uniformly filled. Further, by providing a discontinuous intermittent discharge port, it becomes possible to distribute the granular materials to the individual containers, which is realized by the screw conveyor having the conventional shutter and the shutter driving mechanism. .

[0021] A sensor provided at the lower part of the transport / distribution device for detecting the amount of particulate matter in the container is attached, and the casing is rotated based on the detection value of this sensor to control the discharge position and amount of particulate matter. It is possible to automatically control the amount of the particulate matter discharged from the outlet to discharge an appropriate amount, and to fill each partitioned container with a desired amount. In addition, automatic control can be performed by using a personal computer.
