Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a positioning unit that controls a machine tool such as a robot according to data from a programmable controller.

[Conventional technology]

A conventional positioning unit of this type is shown in FIG. 2 in the figure, 1 is a positioning unit and 1
It is connected to a programmable controller (not shown) (hereinafter referred to as PC) through a PC interface 11, and includes a data storage memory 12 configured by the PC for storing device determination data, etc., and a program content indicating processing steps within the positioning unit 1. Stored system program memory 1
3, and a CPU 14 that controls data writing and reading into and from the data storage memory 12 and system program memory 13.

2 is connected from the positioning unit 1 by a peripheral device interface 15.21 to a machine tool (not shown).
It is a peripheral device for monitoring the positioning operation contents of the CPU 22, which controls the data transmitted and received via the peripheral device interface 21, and the CPU 22 controls the positioning data, origin return data, and parameters from the positioning unit 1. It is composed of a CRT 23 that displays user data such as on a display, and a keyboard 29 that is connected to the CRT 23 and operated to read and write data. A servo amplifier 3 is connected to the external interface 16 of the positioning unit 1 and drives a motor 4 of, for example, a robot (not shown) according to the data of the positioning unit 1.

The conventional positioning unit 1 is constructed as described above, and is moved from point A to point C via point B as shown in FIG. 3, for example.

The operations of the positioning unit 1 and the peripheral device 2 that monitors the operation of the positioning unit 1 when performing work at each location will be described with reference to the flowchart shown in FIG.

First, user data such as positioning data, return-to-origin data, parameters, etc. related to movement from point A to point B is
The positioning unit 1 receives the user data from C, and the user data is written into the data storage memory 12 under the control of the CPU 14 (step 201). After such a user data storage operation, when the PC specifies movement from point A to point B [step 202] and the PC turns on the start signal (step 203), the CPU 1
4 is based on the user data written in the data storage memory 12 in step 201, the external interface 1
6 to drive the servo amplifier 3. The motor 4 is driven by this drive, and the current location, output speed, error information, etc. during this drive are displayed on the screen of the CRT 23 of the peripheral device 2 and monitored (step 20).

This display remains until the machine tool reaches point B.

When reaching point B, the machine tool performs work such as screw tightening and cutting (step 206), but the contents of this work are not displayed on the CRT 23. After completing the work, the PC designates the next number 101 as positioning unit 1 (step 20).
7) L, similarly to the above-mentioned operations, turns on the start signal (step 20B), is monitored by the peripheral device (step 209), and when it arrives at point C, performs the prescribed work (
Step 211), ends. Here, the peripheral device 2
As shown in step 204 in FIG. 4, the monitor contents are the current location, output speed, and error information, and the work contents (screw tightening, etc.) of the machine tool at point B, for example, are not displayed.

[Problem that the invention seeks to solve]

Since conventional positioning units are configured as described above, they can only monitor the current location, output speed, error information, etc., but cannot monitor comments indicating, for example, the direction of travel or the content of work at a certain point. was there. Furthermore, if a comment is to be displayed, the PC and the positioning unit must be synchronized and the comment must be displayed on a dedicated external terminal.

Another problem was that it required difficult programming.

This invention was made to solve the above-mentioned problems, and it is possible to store comments given to user data in the positioning unit, and also allows the user to read comments from a PC or peripheral device when necessary.
The purpose is to obtain a positioning unit that can be written and modified.

[Means for solving problems]

The positioning unit according to the present invention includes a comment memory for storing comments therein and a comment saving memory in a dedicated peripheral device connected to one positioning unit, and the positioning unit stores comments from an external PC in the comment memory. By storing comments in the peripheral device CRT or keyboard, comments indicating the work contents of the robot, robot, etc. driven by the positioning unit can be displayed and monitored at desired times.

[Effect]

The comment memory and the comment saving memory according to the third aspect of the present invention are designed to store comments that cannot be stored in the data storage memory of the positioning unit, so that the operation contents of the robot, etc. can be displayed as comments on peripheral devices, and the Comments can be read, written, and modified.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the WIJ1 diagram. In the figure, the same reference numerals as in FIG. 2 are the same, and the explanation thereof will be omitted here. In the figure, reference numeral 17 is a comment memory provided within the positioning unit, which can be written, read, modified, and accessed from an external PC or peripheral device. Reference numeral 25 denotes a comment saving memory provided in the peripheral device 2 installed at a position away from the positioning unit 1, and is a memory for reading and modifying comments in the peripheral device 2.

Next, the operation of the above embodiment will be explained. First, user data such as positioning data, return-to-origin data, and parameters are transmitted to the positioning unit from an external PC (not shown) connected to the PC interface 11 of the positioning unit 1 or from the peripheral device 2 connected to the peripheral device interface 15. 1, in the positioning unit 1, the CPTJ 14 stores the user data in the data storage memory 12 in accordance with the system program stored in the system program memory 13. Next, the comment given to the user data is similarly stored in the comment memory 1T from the PCl or the peripheral device 2. The comment contents stored in the comment memory 1T are also input into the comment 1 save memory 25 in the peripheral device 2. After that, when a startup command is received from the PC or peripheral device 1, the CP is activated according to the contents of the user data input earlier.
U14 sends a drive command signal to servo amplifier 3 via external interface 16 to drive motor 4 of a robot (not shown) or the like. After driving 1 For example, at step 2040 in FIG. 4 showing the operation flow of a conventional unit,
When the keyboard 24 in the peripheral device 2 is operated, the CRT 2
For example, a comment indicating that a screw is being tightened is displayed on the screen of step 3.

It is also possible to read comments written in the comment save memory 25, modify them, and then write them.

〔Effect of the invention〕

As described above, according to the present invention, since the comment memory and the comment saving memory are provided in the positioning unit and the peripheral device dedicated to this positioning unit, it is possible to store comments on user data. At the same time, comments can be displayed on the screen.1 For example, detailed robot work details (screw tightening,
Cutting, etc.) can be done just by looking at the comments on the screen.

Another advantage is that comment contents can be easily read, written, and modified from a PC or peripheral device.
