Description

Raw material transportation identification system

The present invention is displayed on the monitoring screen installed in the central cab using various sensors and process computer to display the type of raw material transported by the belt conveyor using a variety of sensors and process computers so that the worker can easily identify the raw material generated in the transportation process The present invention relates to a raw material transport identification system that can prevent misfeeds, misfilling tanks, and mismixing.

In general, raw materials such as iron ore or raw materials stacked in the yard are transferred to the destination by a continuously moving belt conveyor, and each raw material is supplied in a post-process or in accordance with a work process performed at the destination. Since it affects the products produced, there is an urgent need for a system that can control them.

In the past, the dispatcher of the central cab informs the operator of the raw material dispenser installed in the yard in which different kinds of raw materials are stored by wire or wireless to inform the work order of discharging the type and supply of raw materials. If the driver incorrectly recognizes the voice, the raw materials with different ingredients may be dispensed. Even if the raw materials are misread, the operator of the central cab cannot check whether the raw materials are dispensed correctly.

In addition, because the raw material dispenser is to discharge the various raw materials deposited in the yard while moving the yard, it is difficult to continuously discharge the same raw material in the characteristics of the raw material dispenser, so the raw materials are discontinuously loaded and transported to the belt conveyor.

Therefore, the operator of the central cab is unable to distinguish between the same raw materials and different raw materials, so that the transport efficiency of the belt conveyor is reduced because the length of the transport for each type of raw material is long to prevent this.

In addition, only the operation and stop status of each belt conveyor can be identified on the monitoring screen of the central cab, so that the raw material transported by the belt conveyor is stored in each storage hopper for each type and then installed by the fixed quantity dispenser installed under the storage hopper. In addition, it was not possible to confirm that the proper ratio was dispensed and the formulation was made, and that the name of the raw material stored in the storage hopper, the order of arrival, and the storage state could not be confirmed. There was a problem that mis-combination is made.

The present invention has been invented to solve the above problems, so that the type of raw material transported in the yard and the transport location and the type of raw material stored in the storage hopper can be easily identified by the operator of the central cab using the sensor and the process computer. Automatically displayed on the monitoring screen to prevent the discharging of different raw materials in the process of work, and to prevent the misfiring, the mixing tank, and the mismixing in the process of mixing the raw materials and to improve the transportation efficiency of the belt conveyor. The aim is to provide a material transport identification system.

In order to achieve the above object, the present invention provides a raw material dispenser loaded in a yard with a raw material dispenser, and supplies the raw material to a destination using a belt conveyor, so as to grasp the type of raw material loaded on the bucket of the raw material dispenser. A weight detection sensor for generating a current value in the range of 4 to 20 mA, a first limit switch having a turning angle reference point of 0 ° to measure the rotation amount of the raw material dispenser, and a second checking point of 339 ° therefrom. The limit switch, the turning angle detection sensor for measuring the turning angle of the raw material dispenser, the yard switching switch for judging the yard where the raw material dispensing machine is located, and the recreational stop position, which is the end point of the traveling rail, are shown as 0M. At the central reference point, a distance detection sensor is installed to detect the travel distance of the raw material dispenser that moves the running rail with reference to 450M. It is a detector that can determine the type of starting material; The first detection sensor and the raw material discharged from the first storage hopper can be confirmed by comparing the raw material is discharged to the raw material dispenser and conveyed by the first belt conveyor and the raw material stored in the first storage hopper A second detection sensor capable of comparing and judging the raw material conveyed by the second belt conveyor for transferring the raw material and the raw material stored in the second storage hopper, and a second conveying raw material discharged from the crusher installed under the second storage hopper. A transfer unit which detects the type of raw material to be transferred by using a third detection sensor that can be compared with the raw material to be transferred by the three belt conveyor and the raw material of the third storage hopper; In order to control each signal detected by the detector and the transfer unit, a signal detector detects various data from a yard, a signal processor to process the signal, a first and a second storage unit to store the detected data, and stored data. It is operated by an information processing unit that controls the display data prepared in advance based on the data, and the type and location of various raw materials loaded in the yard are displayed on the monitoring screen installed in the central cab.
