[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a measuring section, a testing section, a sorting machine, etc. using a belt conveyor in order to measure or test lumpy solids such as coke. This invention relates to a device for feeding the above-mentioned lumps into a conveying means so as to maintain constant intervals while conveying them.

[Prior Art] Conventionally, in a device for feeding lumps onto a belt conveyor, in order to convey the thrown objects at a constant interval, the lumps thrown into the belt conveyor are temporarily held at an IF,
A method has been used in which the above-mentioned restraining means is released when a predetermined distance is reached between the block and the previously thrown lump on the belt conveyor.

[Problem to be Solved by the Invention 1] In the conventional method as described above, in the case of lumps that easily roll, such as coke, acceleration is applied by the belt conveyor after the restraining means is released. transferred,
The distance from the previously immersed mass often changes,
In addition, a device is required to measure the distance between the previously loaded lumps, which makes the device complicated and expensive, and there are problems in that the accuracy of the distance is poor.

This invention has been made to solve this problem, and has a simple configuration, and is a device that can feed the conveyed lumps onto a belt conveyor so that they are accurately lined up and conveyed at regular intervals. The purpose is to obtain.

[Means for Solving the Problems] The apparatus for sorting out lumps according to the present invention comprises a waterwheel-shaped sorting train in which 11 partition plates are fixedly fixed at equal intervals radially from a rotating shaft, and the sorting train. A guide plate that covers the bottom and the opening on one side upstream of the rotation of the bottom is installed at the conveyance start end of the belt conveyor, and the lowest part of the guide plate described in 1-1 is lower than the conveyance surface of the belt conveyor, and the circumference of the above-mentioned alignment train is The rotation speed is configured to be slower than the progressive speed of the above-mentioned l\rut conveyor,
The solids placed one by one in each section of the sorting train are pushed through the partition plates of the sorting train and then transferred to the belt conveyor.

[Function] In the apparatus for arranging lumps of the present invention, the IT cutting plates provided at equal intervals inside the sorting train push the lumps at a speed slower than the conveyance speed of the belt conveyor, and move the lumps to a position slightly lower than the belt conveyor. Since the mass is transferred onto the belt conveyor through the guide plate located at the top, there is almost no acceleration applied to the transferred mass and there is no possibility of it rolling. Therefore, the above-mentioned lumps are conveyed on the heald conveyor in a line with high precision at equal intervals.

There is a cylinder 25 concentric with the rotating shaft 23 and a plurality of partition plates 21 radially spaced from the rotating shaft 23 at equal intervals, fixed to the side plates 24 and 24, and shaped like a waterwheel. A guide plate 22 is provided to cover the bottom of the sorting train 2 and an opening on the rotational upstream side of the bottom. Side plate 2
4 and the walls of the cylinder 25 move to the bottom of the lowest part as the sorting train 2 rotates, they move along this guide plate 22 and move outside. The inner position of the bottom of the guide plate 22 is located at the belt conveyor l indicated by L.
The train 2 is arranged so that it has a step slightly lower than the conveyance surface of the train 2.
A guide plate 22 is installed at the conveyance start end of the belt conveyor I. 3 is a suction type feeder, and a vacuum hose 32.3 is connected to a vacuum pump. The suction cup 31 is provided with a suction cup 31, and as it rotates in the direction of the arrow shown in FIG. 2, the suction cup 31 is moved up and down by a plate cam, a cam roller, etc. (not shown).

4 is a rotating cone feeder with a high central part;
5 is a trough-shaped vibration feeder equipped with a vibrator, 6 is a hopper for storing the lumps 8, and 61 is an opening/closing opening thereof.

Next, the operation of the apparatus for arranging lumps, which is an embodiment of the present invention shown in FIGS. 1 and 2, will be explained.

The lumps 8 stored in the hopper 6 fall onto the vibrating feeder 5 when the opening 61 of the hopper 60 is opened, and are sent to the rotating cone feeder 4 by the vibrating feeder 5. The lumps 8 gathered at the peripheral edge of the rotary cone feeder 4 come to F of the suction type feeder 3 as the rotary cone feeder 4 rotates. Among the suction cups 31 of the suction type feeder 3, the suction cup 31 that has rotated to -L of the rotary cone feeder 4 descends and approaches the -E part of the lump 8 below, and starts vacuum suction. After adsorbing the lumps 8, it moves upward and transports the lumps 8 toward the sorting train 2.

When the suction cup 31 that is sucking the lumps 8 rotates over the center of the sorting train 2, the vacuum suction is cut off, so the lumps 8 are separated from the suction cup 31. Fall into the section at the top of the tidying train 2. The fallen lumps 8 roll along the guide plate 22 as the sorting train 2 rotates? to move to the bottom. The lump 8 that has reached the lowermost part (bottom) is pushed by the partition plate 21, moves the guide plate 22'' by IH, and is transferred to the conveyance surface of the belt conveyor 1. At this time, the driving mechanism of the belt conveyor I, the sorting train 2, and the suction feeder 3 is set so that the speed of the lumps 8, that is, the circumferential speed M of the peripheral edge of the sorting train 2 is slightly slower than the conveyance speed 1 of the belt conveyor I. are configured to interlock, so that no sudden force is applied to the lumps 8, and the distance between the partition plates 21 of the sorting train 2 and the belt conveyor l
The material is transported while correctly maintaining a predetermined constant interval d determined by the transport speed .

In this case, as a result of various experiments, the relationship between V and ■ is as follows:
It has been found that the lumps 8 can be stably conveyed when the distance is in the range of (0,5 to 1).

Further, the difference in level between the inside position of the bottom of the guide plate 22 and the position of the conveyance surface of the belt conveyor l is equal to the diameter of the sorting train 2.
It varies depending on the situation, but the diameter of the marshalling train 2 is 440 m.
In the case of m, the value of [l was approximately 30 mm, and stable conveyance was performed.
