Abstract

PURPOSE:To execute the management of work and production unifically at a real time by displaying a command signal outputted from a computer on an operator's terminal such as an NC machine and supplying data such as the change of the contents of the command from the input means of the terminal. CONSTITUTION:Direct NC machines 4-6, general machines 7-11, etc. are connected to a computer 1 in a working line which is provided with a terminal through a bus line and these units are controlled by the computer 1. The operator's terminal 12 is provided with a display part D consisting of a display board 13a or the like and an input means I consisting of a keyboard 14a or the like to execute the display of data and the exchange of information between said computer 1 and the operator. Consequently, the operator can exchange the information for the working status of FA, and when delay is generated due to the inconsistency of working status or the like with the contents of a program at the exchange of the information or after the passage of an optional period, can supply data to correct the succeeding program from the terminal 12 to the computer 1 through an input means I.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to 11th FA, etc., when performing work such as machining or automatic assembly under the aid of a computer. , or an operator terminal for recording the results thereof.

[Prior Art] Recently, in the field of metal processing, workpieces are often processed on a line or in a job shop.

The machines used in this case are a mixture of automatic machines such as NC machines and robots that are wired to a computer, and manual or semi-automatic general-purpose machines that are not wired to a computer and are operated by an operator. Operators of machines that require manual operation need to receive information about the working status of NC machines and robots from a computer online or offline while proceeding with work using manually operated machines or the entire line. That is, for example, if a trouble occurs, including work interruption circumstances occurring on the NC machine side of the line, manual machine side, or the operator himself, the operation of the machine on the line is stopped, This is because the problem must be resolved before restarting.

[Problems to be solved by the invention] However, in the above case, for example, the number of processed items per day on the line is pre-programmed in the computer, so if the line operation is interrupted midway, the program Processing of the planned quantity will not be completed within the specified operating time.

Traditionally, when the above-mentioned production control problem occurred, it was dealt with by, for example, modifying the program for the next day's scheduled quantity after the operating hours, but this is not rational. There is a side.

In other words, the number of unfinished machining in the above example is an error in production management, so if such error is not recovered or eliminated at the time it occurs, it would be impossible to prevent such error from occurring many times during the operation time. If this happens, these errors will accumulate as processing errors for production control on the line after one day of operation, and there is a high possibility that it will be difficult to modify the program.

[Means and effects for solving the problem] The present invention was made in view of the current state of work in FA as described above, and its configuration is based on automatic or NC machines whose operation is controlled by a computer. The contents of the command signal supplied from the computer to the machine side are visually or audibly displayed on the operator terminal in the appropriate processing line or job shop formed by the manual or semi-automatic machine operated by the operator of the semi-automatic machine. It is characterized in that, while displaying the information in a form that is possible, data for changing the contents of the command, establishing a new one, or creating a work record is supplied to the computer from an input means formed on the terminal by touch or voice. That is.

[Example] Next, embodiments of the present invention will be described with reference to the drawings.

Fig. 1 shows an example of a processing line in which the terminal of the present invention is installed, in which 1 is a computer in an FA or job shop, and two FMS lines 2 are connected to the pass line.
, 3.3 direct NC machines 4 to 6.5 general-purpose machines 7 to 11 are connected, and these 1 to 11 form an FA line or job shop whose operation is controlled by the computer 1.

Although not shown, the computer 1 is also connected to a main computer.

Since the operator terminal 12 of the present invention is provided for the general-purpose machines 7 to 11 described in Section 2, this point will be explained below.

Operator terminal 12, display panel 13 with liquid crystal, etc.
Sound generating means 1 consisting of a2 indicator light 13b, speaker, etc.
It is equipped with a display section 3c and an input means I using a keyboard +4a or a microphone 14b.The display section displays command signals such as voice or digital signals, and the input means R is an operator's input means inputted from the microphone 14b. It is configured such that various data can be supplied from the operator side to the computer 1 through voice or keyboard operations, and between the computer 1 and the operator,
For example, the following information can be exchanged via the terminal of the present invention and the above-mentioned display section and input means (2).

FIG. 3 is a time chart showing an example of the operating state of information exchange between the display section and the input means I in the terminal 12.

Thus, the content A of the command signal from the computer 1 is first displayed on the display panel 13a. After a short pause tl, the content A is outputted as a sound by the sound generating means 1 such as a speaker.
3c and the display enters 2 after the next pause.

When the operator views and confirms the display content A on the display section from the time 11 to the expiration of time L2, the operator sends a signal B indicating confirmation via the keyboard 14a or the microphone 14.
Give from b. This signal B is supplied to the computer.

Here, it is assumed that the FA shown in FIG. 1 is programmed to start operating after the above-described information exchange between the computer and the operator.

In this way, after the FA shown in FIG. 1 starts operating, for example, every time an appropriate iB operating time ut elapses
A means for operators to input information about work progress, etc.■
By operating the FA and supplying the data C, D, . . . to the computer 1, the computer 1 and the operator can exchange information regarding the working status of the FA.

Therefore, when the above information is exchanged or after an arbitrary period of time has passed, the current work status or cumulative work status of the FA does not match the program content, for example, the work has not been carried out, or the work has been carried out but is interrupted. If there is a delay in the implementation time due to the above, input the data for modifying the next program to the input means I from the terminal 12 in the same way as the above data C, D, etc. It can be operated and supplied to the computer 1.

In addition to the periodic supply of data to the computer l from the operator as in the example above,
Of course, this can be done at any time. This is because, in an emergency, it is necessary to be able to stop the operation of the entire FA line at any time.

Furthermore, the types of information that can be exchanged between the computer and the operator terminal 12 are of course not limited to those in the example above, and furthermore, both 1 and 12 can exchange information not only online but also offline. can.

Therefore, the terminal 12, which is not always connected to the computer 1, can be made portable.

[Effect] The present invention is as described above, and the F
Work or production management on the A line, etc. can be performed in a unified manner in real time from the perspective of the entire line. Therefore, even if a problem such as a stoppage of operation occurs at any time during operation, it will be possible to Since work delays caused by such problems can be resolved or recovered, extremely rational work or production can be carried out, and the industry can improve.
1- Extremely useful.
