Abstract

PURPOSE:To execute the changeover of operation by one-man/multi-operation without impairing functionality and operability, with high reliability, easily and inexpensively by composing of a one-man/multi-operation device with which the function of a desk is switched based on the job of operator. CONSTITUTION:At the time of operation, right and left operators 5, 6 select operating supplies corresponding to respective jobs with operation function selecting switch 4. Ordinarily, Y is selected by the left operator and X is selected by the right operator. The result of operating supplies selection is sent to a one-man/multi-operation switching device 10 as a right and left operating supplies selection number 9 and, after passing through the interlock condition check of right and left switchable condition signal 12 in the device 10, the process recognition of the right and left operating supplies is formally executed. Then the operation of (a), (b), (c) of the switch 8 for setting screw-down of the operating supplies 2 on the left desk is validated. On the other hand, the operation of A, B, C of the switch 7 for setting speed of the operating supplies 3 on the right desk is validated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating device used for operating a rolling mill for thick plates and the like.

[0002]

2. Description of the Related Art Conventionally, for example, an operating device for a plate rolling mill has been designed on the premise of two-person operation. Therefore, the operation desk also has operation supplies arranged in front of each operator according to the role of each operator, and even when the roles of the operators are changed, the operation is performed by changing seats.

[0003]

By the way, when considering the correspondence to the one-person driving era in which the control technology of recent years has become more accurate, the above-mentioned driving operation device smoothly shifts from the two-person driving to the one-person driving as it is. It is difficult. That is, even after the automation level of the rolling control is improved, if there is some operation intervention, some intervention becomes impossible due to the layout of the operation article, and there is a problem in terms of productivity and cost.

Further, conventionally, when a part of the operating article fails, it is essential to stop the production and restore it. The present invention has been made in view of the above points, and an object of the present invention is to provide a rolling mill operation device having a degree of freedom.

[0005]

A rolling mill operation device according to the present invention is based on an operation desk in which one or a plurality of people can operate and operation products are arranged at the driver's position, respectively, and a role of the driver. And a one-man / multi-operation switching device for switching the function of the desk. With such a configuration, one-man / multi-operation can be realized easily, at low cost, with high reliability without impairing the conventional functions and operability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An operation device for thick plate rolling according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing one embodiment of the configuration of the present invention. Operation desk 1 has 2
In order to allow operation by one person or one person, a speed setting switch 7 and a pressure reduction setting switch 8 are provided as the same operation article in front of the left and right operators 5, 6, and the speed setting switch 7 is provided in the center thereof. The operation function selection switch 4 for the reduction setting switch 8 is arranged. There is a one-man / multi-operation switching device 10 for identifying and controlling the operation article of the operation desk 1, and finally an electric control device (sequencer) 11 for controlling the process / drive system based on the information is included. It is a composition.

At the time of operation, the left and right operators 5, 6 select the operation article according to their respective roles with the operation function selection switch 4. Normally, the left operator selects Y and the right operator selects X. The operation product selection result is sent to the one-man / multi-operation switching device 10 as the left / right operation product selection signal 9, and after the device 10 obtains the interlock condition check of the left / right switchable condition signal 12, the left and right operation products are officially selected. Processing recognition is performed. With this, in the operation article 2 on the left desk, the operation of the pressure reduction setting switches 8 for a, b, and c becomes effective. On the other hand, in the operation article 3 on the right desk, the speed setting switches 7 for A, B, and C become effective.

The operation signals 14 of the speed setting switch 7 and the pressure reduction setting switch 8 of the left and right desks are input to the switching device 10, respectively, but only the operation signals recognized by the above-mentioned left and right switching processing have the same function. It is transmitted to the electric control device 11 as an operation article unifying signal, and is output to the process controller (not shown) as the control signal 16.

In addition, the operation signal 15 is used for signals requiring quickness in signal processing, such as intervention in the rolling reduction value of the rolling mill.
The electric control device 11
To the right and left switching processing signal 13 in the electric control device 11.
Therefore, the valid one is the output target.

In order to process the result display lamps on the operation supplies 2 and 3, the switching device 10 receives the result signal 18 output from the electric control device 11 based on the result information 17 and the like, and the same result lamp is applied to the same operation product on both the left and right sides. Output a display signal. As a result, the operating supplies 2 and 3 on both the left and right desks all display the same results regardless of the selection result of the operation function selection switch 4.

The shift from the two-person operation to the one-person operation by the operator 6 is performed by selecting both the right desk function selection of the operation function selection switch 4 in the X and Y directions, and thereafter all the driving operations are performed by the right desk operation article 3. It will be possible.

[0012]

As described above, according to the present invention, it is possible to easily realize one-person / two-person operation switching using the same operation desk. Not only can the shift to single-person operation be done quickly without the need to modify the desk, etc., but even if one side of the desk malfunctions on one side (such as a component failure), the desk function on the other side can be used for production, etc. The system is also useful in terms of reliability. In addition, it has excellent effects in terms of operator training at the mounting equipment, such as the fact that new employees can be trained using a vacant desk when driving alone.
