Description

Automatic Control Device of Unloader Skirt Plate in Raw Material Transporting Facilities}

The present invention relates to a skirt plate subordinate to an in-flight chute under the unloader in an ironworks raw material processing facility. In particular, the cargo is unloaded at a point where the unloaded cargo is loaded into the belt conveyor through the belt. The present invention relates to an automatic control device of an unloader skirt plate for processing raw materials, which assists to properly stack the conveyor.

In general, the unloader equipment of the raw material processing equipment is a device that unloads the goods imported by sea and puts them on the belt conveyor. In one unloader, four quay-wall belt conveyors (1-1,1-) are shown. 2,1-3,1-4) are installed and the skirt plate (3) installed on the unloader equipment has a transport (5) such as iron ore, coal, which is poured over the belt conveyor through the chute, and falls out of the belt conveyor. The fall 8 is prevented from occurring.

On the other hand, the rubber plate 4 is attached to the skirt plate 3, but the rubber plate 4 of the skirt plate is unloaded by the belt conveyor other than the inner wall belt conveyor, which is in contact with the inner wall belt conveyor. Regardless of whether the belt conveyor is continuously conveyed in contact with the belt conveyor, the wear of the skirt rubber 4 and the belt conveyor may occur prematurely. 8) There was a problem causing. In addition, this shortens the life of the fallout process and the rubber and belt conveyor, resulting in excessive cost for replacement.

The present invention has been made to solve the problems of the prior art as described above, during the unloading operation of the unloader to raise the skirt plate to prevent friction with the belt conveyor to prevent premature wear and unloading of the transport unloaded from the other unloader It is an object of the present invention to provide an automatic control device for the unloader skirt plate for processing raw materials, which does not disturb the flow and eliminates the formation of the cargo.

The unloader skirt plate automatic adjustment device of the present invention for achieving the above object is to prevent the skirt plate from rubbing with the belt in order to improve the life of the skirt portion and the skirt plate and the conveyor belt to prevent falling of the goods on the belt. An up and down control unit for moving the skirt unit up and down, a left and right adjustment unit for adjusting the width by moving the skirt plate left and right, and controlling the up and down and left and right movement of the skirt plate and detecting the occurrence of a shipment of cargo It is provided with a control unit.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing preferred embodiments.

3 and 4, the unloader skirt plate automatic adjustment device of the present invention, the skirt portion for preventing falling of the transport object, the upper and lower adjustment portion for moving the entire skirt plate up and down, and adjusts the left and right width of the skirt plate Left and right control unit for controlling, and can be divided into an operation control unit consisting of a sensor and a computer to control the entire device.

This will be described in detail as follows.

As shown in FIGS. 3 and 4, the skirt plate 11 of the unloader has a suitable thickness to withstand the impact of the shipment 5 falling off the chute of the unloader, and has a longer length than the unloader chute 6. A plurality of bearings 12 are inserted at appropriate positions in the upper portion. In addition, the skirt rubber 13 is firmly attached to the lower portion of the skirt plate 11 to prevent falls.

And the upper and lower adjustment part constituting the present invention includes a support frame 21 consisting of four rigid pillars, the bottom of which is fixed to the unloader frame 25, the frame 21, the cylinder 22 for adjusting the up and down Is mounted, the other end of the cylinder rod portion is coupled to the connecting table 23, the upper surface of the both sides of the connecting table 23 is mounted '24' shaped support 24.

And in the present invention, the left and right adjustment part is connected to the left and right adjustment cylinder 31 and the rod portion 35 and vertically mounted downward in the center of the support 24, and the main body on both sides of the connector 35, respectively A link assembly composed of a link 32 and an auxiliary link 33 is coupled, and the other end of the auxiliary link 34 is coupled to a link bracket 34 attached to the upper end of the skirt plate 11. A long rod-shaped guide bar 36 extends through the skirt plate 11 horizontally with the support 24 so that both ends are fixed to the left and right connecting tables 23.

On the other hand, the operation control unit for controlling the up and down control unit and the left and right control unit of the present invention made as described above in the present invention support the hydraulic pump (42) and the cylinder (31) connected to each cylinder via a cable (43) ( 24) a computer 41 mounted at the bottom and installed to receive a signal from the sensor 44 via an electrical cable 45 and a detection sensor 44 for detecting a transport amount.

Hereinafter, the operation of the unloader skirt plate automatic adjustment device of the present invention made as described above with respect to FIG.

As shown in FIG. 5, when unloading is started at the unloader 2, the unloading information of the unloader and the amount of transportation detected by the amount detecting sensor 44 are applied to the computer 41 to determine the width at the CPU of the computer 41. By giving an operation command to the left and right adjustment cylinder 31 (S1).

Accordingly, when the left and right adjustment cylinder 31 is stretched and operated to a predetermined length, the main link 32 and the auxiliary link 33 move up and down, and the width of the skirt plate 11 is expanded or reduced. It moves horizontally along the guide bar 36 via the bearing 12 installed in (S2).

Subsequently, when the width adjustment of the skirt plate 11 is completed according to the program sequence of the computer 41, the operation command is given to the upper and lower adjustment cylinders 22 to lower the entire left and right adjustment unit including the skirt plate 11 to an appropriate height. (S3).

In addition, when the computer 41 detects that the transportation object 5 transported on the belt conveyor 1 is loaded by the transportation detection sensor 44, the computer 41 operates the left and right adjustment cylinder 31 to operate the width of the skirt plate 11. By appropriately adjusting the guide to eliminate the knitting (S4).

Then, when the unloading completion information is applied to the computer 41 in the unloader 2, the up and down adjustment cylinder 22 is operated to raise the skirt plate 11 and finish the operation (S5).

According to the present invention as described above, when the unloader does not work, the skirt plate 11 and the belt conveyor 1 and the belt conveyor 1 can be lifted up to prevent friction with the belt conveyor 1. It prevents premature wear and does not interfere with the flow of cargo unloaded from other unloaders located in the previous process, and it has a practical effect such as detecting the case when the cargo is stacked on the belt conveyor and automatically eliminating the knitting. .
