Description

  The present invention relates to a rolling coil management system capable of visually displaying on a screen a storage state of a rolling coil manufactured by hot rolling of a steel material.

  2. Description of the Related Art Conventionally, a rolling coil management system has been used in order to grasp the storage status of rolled coils manufactured by hot rolling of steel materials. The rolling coil management system will be described below with reference to FIG.

  FIG. 5 shows a rolling coil place L, and an overview viewed from above. The left end side of the yard L is an exit of the hot rolling line, and the left end side is a rolling coil shipping direction (white arrow). On the left end side of the parking space L, an overhead crane C that can move in the illustrated X-axis direction stands by. Although not shown, the overhead crane C is provided with a gripping device that can grip and lift or unroll the rolling coil. The gripping device is mounted on the overhead crane C on the Y axis. Can move in the direction.

  The overhead crane C and the gripping device are moved on the yard L in accordance with instructions from the terminal device in the rolling coil management system. For example, when carrying the rolling coil Rn, the rolling coil is installed at the exit of the hot rolling line. It is lifted and then transported to the target position of the storage space L, where it is lowered and stored in a predetermined position. Or when shipping the rolling coil already stored in the storage place L, it lifts in this storage position and conveys it to a shipping exit.

  In this way, by moving the gripping device in the X-axis and Y-axis directions on the placement site L, the rolling coil Rn can be freely carried into, removed from, or moved to the placement site L. The moving operation of the overhead crane C and the gripping device is performed when the operator inputs predetermined information to a terminal device that can communicate with the rolling coil management system.

  In this input, the operator inputs predetermined information on the rolling coil to be handled from now on, for example, coil product number, coil width, coil thickness, coil weight, classification, coil movement destination position, etc., using a keyboard, etc. The coil loading position, coil moving time, coil paying time, coil shipping time, etc. are automatically detected on the rolling coil management system side and stored together with predetermined information in a storage device provided in the management system.

  FIG. 5 shows a situation in which a plurality of rolling coils are arranged in the coil place L by the above moving operation. The solid line frame displayed in the figure indicates that the rolling coil Rn is placed at that position, and the broken line frame in the figure indicates an empty state in which the rolling coil Rn is not disposed. Since the rolling coil manufactured in the hot rolling line is cooled by being stored in the coil place L, the operator can perform rolling in the coil place L in consideration of the change in the temperature of each rolling coil. While observing the coil arrangement state, the arrangement of the rolling coils is managed.

  By the way, when the operator manages the arrangement of the rolling coils, not only the visual observation of the arrangement state but also the screen X0 shown in FIG. Can be displayed on a terminal device that can communicate with In this screen X0, only the character information stored as a database in the storage device of the rolling coil management system is displayed.

  On the other hand, it has been proposed to display the arrangement status of the merchandise storage location on the screen of the terminal device so that it can be intuitively grasped (see, for example, Patent Document 1). In this terminal device, location information such as the allowable capacity of the location where the product is placed and product information such as the product dimensions and the number of stackable stages are acquired from the distribution base server via a communication network, and the acquired information is Based on this, the remaining number of stacked products is judged, and the availability of the warehouse considering the number of stacked products is displayed graphically on the screen of the terminal device so that it can be grasped visually and intuitively. .

  Since the rolled coil manufactured in the hot rolling line is cooled by being stored in the coil storage L, when the operator manages the rolled coil, the operator must grasp the temperature status of each stored rolled coil. The storage management of the rolling coil cannot be performed properly. However, in the terminal device in the conventional rolling coil management system, the coil information is simply displayed in a character base, and the temperature information of the stored rolling coil is obtained directly from the displayed information. I can't. In order to properly manage rolling coil storage, it is necessary to grasp the cooling status with reference to this coil information. This grasping requires operator experience and intuition, and appropriate rolling coil storage management. In particular, this has hindered optimal coil placement.

  Further, Patent Document 1 proposes that the vacancy status of the warehouse can be displayed graphically on the screen of the terminal device so that it can be grasped visually and intuitively. However, the product stored in the warehouse does not change its state with time, so the idea of immediately displaying the free space in the warehouse is graphically displayed. It cannot be applied to storage management.

  Therefore, in the present invention, the rolling coil management system capable of visually and directly displaying the storage status of the rolling coil manufactured from the steel material by hot rolling on the screen including the thermal aging of the rolling coil. The purpose is to provide.

  In order to solve the above problems, in the rolling coil management system of the present invention, coil information including at least coil identification information, arrangement time information, and arrangement position information is stored corresponding to a plurality of rolling coils arranged in the coil place.

  As described above, in the rolling coil management system of the present invention, each arrangement elapsed time is obtained from the arrangement time information for each rolling coil stored in the coil information storage means, and the display varies depending on the length of the arrangement elapsed time. A figure corresponding to each rolling coil having a form is created, and a position on a map relating to the coil placement is specified based on the arrangement position information for each rolling coil, for each rolling coil in the coil placement. Since map information representing the arrangement is created and displayed on the terminal device screen, the operator can easily visually determine the length of the arrangement elapsed time for each rolling coil from the rolling coil map displayed on the screen. Can be read.

  For example, if the length of the arrangement elapsed time read is short, the temperature of the rolling coil is high, or if the arrangement elapsed time is long, the temperature of the rolling coil is low due to cooling during storage. According to the length of the elapsed time, it is possible to visually and directly grasp the temperature state of each rolling coil. Therefore, it becomes easy to store and manage stable rolling coils without depending on the experience and intuition of the operator, and efficient coil storage can be used.
