Description

[Detailed description of the invention] The present invention is a method of supplying a plurality of types of granular articles onto a conveying line in a manner that they are stacked on top of each other, and transporting the plurality of granular articles to a predetermined position while mixing them. This invention relates to a mixing conveyance device.

Conventionally, when two or more types of granular articles are supplied at a fixed ratio and mixed, a means for supplying the granular articles,
The mixed granular articles are conveyed to a predetermined position via the mixing means and the conveying means, or the granular articles conveyed to the predetermined position are mixed in a desired manner by the mixing means. This method therefore requires both mixing means and conveying means.

The present invention uses a conveying means to simultaneously perform mixing during conveyance.

The present invention will be explained below based on examples.

The conveying means used for conveying and mixing of the present invention is as follows:
A horizontal flight conveyor in which all flights move on the same plane is used, and a plurality of horizontal flight conveyors are used so that their supply and discharge positions are located above and below each other.

At a predetermined position above the first stage horizontal flight conveyor 1, hoppers H1, H2, H3, etc. for supplying articles are provided at required intervals according to the number of types of granular articles to be mixed. The opening area or opening time of the hopper shall be set in advance in accordance with the supply rate of the articles.

The hoppers H1, H2, H3, . . . are installed along the direction of movement of the horizontal flight conveyor 1. In addition, a discharge hole 1a is located at a predetermined position in the trough of the first stage horizontal flight conveyor 1.
A hole is made in advance, and a supply position of the second-stage horizontal flight conveyor 2 is provided below the discharge hole 1a. The main goal of this second stage horizontal flight conveyor 2 is to mix and convey multiple types of granular articles supplied from the first stage without providing a hopper, and the articles conveyed to a predetermined position are A discharge hole 2a is provided at a predetermined position in the trough of the conveyor 2 for supply to the third stage horizontal flight conveyor. Further, a third horizontal flight conveyor 3 is provided below the second horizontal flight conveyor. In this way, two or more horizontal flight conveyors are installed with their supply and discharge positions facing each other vertically and with a predetermined height difference. be horizontal and provide steps, or the horizontal flight conveyor in each stage may be inclined so that the supply side is low and the discharge side is high; furthermore, the number of stages of this horizontal flight conveyor may be mixed. It shall be determined based on the rate and transportation distance, etc. Further, the horizontal flight conveyors of each stage are assumed to be in a straight line as shown in FIG. 2, or connected to each other at a certain angle as shown in FIG.

When the predetermined amount of granular articles currently fed onto the horizontal flight conveyor 1 by the hopper H1 comes below the hopper H2 due to the drive of the conveyor, a predetermined amount of the next different type of article is supplied from the hopper H2. In this case, it is piled up on the previously supplied granular article. In this way, articles of different types or of the same type are sequentially supplied from the hopper in a stacked manner onto the horizontal flight conveyor, and are transported on the trough by the horizontal flight 1b by the drive of the conveyor. During this horizontal flight, the layers of the stacked articles are broken down and rough mixing is performed. When the article reaches the discharge hole 1a, it falls through the hole 1a onto the second horizontal flight conveyor. During this falling, the different types of articles are stirred and mixed together. Further rough mixing is performed when the mixture is transferred on the second horizontal flight conveyor in the horizontal flight 2b. In this way, various articles are mixed and conveyed to a predetermined position when they are sequentially transferred on the horizontal flight conveyor and when they are dropped onto the next horizontal flight conveyor for transfer.

In addition, when transferring from the first stage to the second stage and from the second stage to the third stage, the discharge hole of the upper stage is not limited to one location, but can be performed from any location (two or more locations). Furthermore, one end side of the horizontal flight conveyor can be left open, and the transfer can be made from this open position to the horizontal flight conveyor at a lower level.

Therefore, according to the present invention, since the conveyed objects are transferred between horizontal flight conveyors that are arranged horizontally so that all flights move on the same horizontal plane, mixing and crushing on the horizontal flight conveyor is possible. The centrifugal force at the circumference of the flight increases the discharging effect, and the flight is horizontal, so
Even if there is some leftover material, it will not fall to the bottom of the conveyor, and the leftover material will be mixed and crushed during circulation and can be taken out the next time.
Unlike a belt conveyor, multiple discharge ports can be provided as appropriate, and even if the next conveyor is full, the discharge port will automatically close without installing a control device and switch to mixing-only operation. ,
When two or more types of articles are conveyed, mixing and agitation are automatically performed at the same time without using a mixing means, making it suitable for conveying articles that are mixed and conveyed at the same time. It has the advantage of being able to be transported.
