Abstract

(57) [Abstract] [Purpose] It is an object of the present invention to provide a method for switching production modes in production equipment, which is capable of switching operation modes only when it is not dangerous for an operator. [Configuration] By having the operation mode, operation state management function, and operation mode switching determination means 21, it is possible to safely perform mode switching of production equipment.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production mode switching method in production equipment.

[0002]

2. Description of the Related Art In a production facility, the operation may be temporarily stopped and checked for each unit during a production test. 1
After the block operation, when the series of production operations are not completed, the operation mode can be switched to the maintenance mode.

However, in this state, the motor is rotating and it is dangerous for the operator to continue the maintenance thereafter.

[0004]

Therefore, according to the present invention, after confirming the operation of each unit at the production test in the production facility,
The purpose is to switch the operating mode only when it is not dangerous to the operator.

[0005]

In order to achieve this object, the mode switching method of the production equipment according to the present invention reads the production mode information input from the operation panel and the reading means and the reading means. The mode includes a mode switching determination unit that determines whether or not the mode can be switched, and a control unit that controls the operation of the production equipment.

Further, the mode switching method of the production facility according to the present invention is characterized in that the mode switching is performed by judging whether or not the mode can be switched by combining the production mode information input from the operation panel with the state of the production facility. To do.

[0007]

With this method, during the production test of the production equipment, it is not possible to switch to another mode until a series of production operations are completed after confirming the operation for each unit, and only when the operator is in a safe state. The mode is switched.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings showing the embodiments thereof. FIG. 1 is a block diagram of an apparatus used for implementing a mode switching method of a production facility. In FIG. 1, reference numeral 1 denotes an operation panel provided with a mode selection key of a production facility, which inputs input information to a mode switching device 2. The mode switching management device reads 20 input information input from the operation panel and 22 production equipment status management means for managing the operating status of the production equipment and information of the read means and information of the production equipment status management means. Also, it comprises 21 mode switching determining means for determining whether or not mode switching is possible. When it is determined that the mode should be switched, the information is input to the control unit of 3. The four production facilities operate according to the command signal from the control unit.

FIG. 2 shows the processing contents of the mode switching judging means. When the mode switching information is input to the reading means, the mode switching information is input to the control section only when the information of the production facility status managing means has completed the series of operations in the current mode.

As described above, according to this embodiment, during the production test of the production equipment, the operation mode cannot be switched until a series of production operations are completed.
At the time of maintenance by the worker, there is no danger that the production equipment is rotating the motor.

[0011]

As described above, according to the present invention, during the production test of the production equipment, the operation modes cannot be switched until a series of production operations are completed. Since there is no danger that the equipment is rotating, the safety of the production equipment is improved.
