Abstract
The present invention provides the overhead crane operator in real time with steel location tracking and screening plan for all processes from goods receipt (steel unloading) to goods issue (pretreatment), replacing the role of the existing signal number and improving the accuracy of the screening. At the same time, it is possible to accumulate the plan by 100% system excluding the operator's thought in all sorting processes, and the present invention directly provides the crane engineer with the plan information of the steels to be sorted, thereby reducing the role of the number of signals and time difference of information. Eliminating the need for more efficient and real-time steel plan management.
Description
The present invention is a method of providing real-time steel loading information of the shipyard steel storage, more specifically, by providing the overhead crane worker of the steel storage in real time in the file storage information and screening plan information and absence information when lifting, The present invention relates to a steel loading information providing method that provides steel loading planning in real time to reduce the number of signals), increase the accuracy of the screening, dramatically reduce the steel screening time, and increase the crane operation rate.
Steel ships entering the steel loading dock at the shipyard where the ship is built are unloaded by the trailer, and the worker decides the bays in the stockyard by considering various conditions such as the stockyard situation for each bay and daily workload, The steel is deposited and managed. The worker divides the stockyards in the yard by file, and manages inventory such as steel stocking / selection at the designated file number. Steel is input into sorting, stacking, and pretreatment in consideration of the same block and assembly process date used, and the sorting operation takes a large weight. Conventionally, the file address of the destination to which the steel should move is written by using a paint brush for each steel that the worker (signal number) needs to sort, and the overhead crane worker recognizes and moves the written file number.
At this time, a dangerous situation may occur due to the crane magnet inadvertently caused by the inadvertent crane operator. And the number of signals should find the steel to be screened in the file, the member information is displayed next to the steel, if the member size is small, it is difficult to recognize the member information, there is a lot of difficulty in selecting the steel.
In addition, if the crane operator is visually restricted due to environmental influences such as weather (rain), night, or the steel number classification is carried out several times, or due to rain, the display status of the file number can not be properly confirmed. Is often happening. In this case, the file number must be checked by another operator and informed by a radio operator of the magnetic crane operator, which causes problems such as increased working time or manual steel classification.

The
As described above, in the conventional steel stock loading operation, the number of signals is checked by marking the steel marking information one by one, and the stacked steel information is checked on a sheet of paper and updated on the transcription management program of the management computer. Therefore, a lot of time and effort are spent in inputting steel goods receipt information.

The steel materials loaded into the daily file (7/1 process, ..) in the
As such, the received and updated steel information is managed by the first, second and third sorting work orders issued by the optimal planning system. Signals printed in this way will be printed to inform crane operators where to move the steel. The work completed by the sorting work order is then updated on the enterprise management program. The number of signals increases due to the number of signals printed on the work order, and the crane driver must always wait for the signal number because the crane operator cannot know the movement information of the steel. And after the work is completed, the status of the work is updated, so the status of the work cannot be known.

Re-arrangement by cutting date by reentry date The steel piled in the
The steels sorted up to the third are placed on the conveyor going to the pretreatment line by the steel dispensing instructions 33 and transported to the pretreatment workshop. After pretreatment, the steels are placed on the
The steel received in this way must be sorted and managed by ship's ship, block, and series for each file after sorting. In the existing case, the worker must grasp the loading status of each file by hand. In this case, not only the worker must check the steel loading status by file, but also need to re-correct each time the steel loading status is changed.
In addition, there is a considerable difficulty in confirming the stacking order of steel files desired by the worker. In order to inject steel into the pretreatment process, inventory management difficulties occur such as continuously checking and modifying the stacking status of files in real time.
Conventionally, after the steel stockpile plan is established, signalers print the plan information so that crane operators can move the steel according to the plan. However, there is a problem that not only too much work is assigned to the signal, but also the time difference of information occurs in the process of updating the work completion after the steel is moved as planned.
An object of the present invention is to manage the loading information and implementation of the plan of all steel from receipt to release on the computer, to manage the position and movement information of the steel from receipt to release, and to reduce the number of workers through paperless In other words, it is to provide a method for providing steel loading information that provides real-time loading of steel loading plans, which enables shortening of periods of future planning through real-time updating of plan execution information and real-time process monitoring anytime, anywhere.
The present invention provides the overhead crane worker of the steel stockpile in real time with the stock load information and sorting plan information and absence information at the time of lifting, reducing the number of workers (signal number), improve the accuracy of the sorting, and significantly improve the steel sorting time To reduce productivity and increase crane utilization.
