Abstract

PURPOSE:To shorten the preparation time by installing a discriminating means for memorizing the work No., tool No., and working program No., onto a workpiece installation jig and outputting the data into a reading device and automatically carrying out the installation of a workpiece, mounting of a tool, and calling-out of a program. CONSTITUTION:The work No., tool No., and working program No. which are memorized in a discriminating means 14 installed onto a workpiece installation jig 7 are read by a reading device 15. The work No. is outputted into an NC device 18 through a controller 16, and a workpiece W is installed onto the jig 7 by a robot 25. The tool No. is outputted into the NC device 18 from the controller 16 by an installation completion signal, and it is judged that a tool magazine 1 is equipped with the necessary tools or not, and a tool preparation signal is outputted. Further, the working program No. is outputted into the NC device 18, and the working preparation is completed. Through the above- described automatic operation, the preparation time can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a machining setup method for machining centers, FMS, etc.

Prior Art Conventionally, in machining setups for machines used in machining centers and FMS, workers check the type and number of workpieces using a process schedule, find jigs, and check the tool list to see if the machine is equipped with the necessary tools. In the past, tools were checked, tools were replenished, and a machining program was called or a new machining program was set.However, this was time-consuming and prone to errors, so automation was considered.

Known technologies related to this automation include
154658, a transport pallet on which a work is placed and transported to a predetermined processing position is attached with an LSI chip that stores information such as the work type and work number, and the information read by a reading means is sent to the NC. There are data reading and writing devices.

Also, as in Japanese Patent Application Laid-Open No. 60-85849, work is transferred from an automated warehouse by a transport robot using signals from a central controller.

There is an automatic setup device, etc. in which a pallet and jigs are transported to a setup adjustment section, a workpiece is fixed on the pallet via a jigs, the workpiece is transported to a machine tool by an automatic guided vehicle, processed, and then stored after the processing is completed.

Problems to be Solved by the Invention These devices, such as automatic attachment of workpieces to pallets or jigs, automatic transportation, etc., are part of the automation from the perspective of a series of setup work processes, but the entire process cannot be completely automated. It was hoped that a new machining setup method would emerge.

Means for Solving Problems Prior to machining, the workpiece number and tool number are stored in the identification means 14 provided on the workpiece mounting jig 7.

The reading device r1115 reads the machining program number, outputs the workpiece number to the NC device 18 via the controller 16, and the NC-controlled robot 25 transfers the workpiece W to the jig 7.
When the installation is completed, the controller 16 is installed again.
Outputs the tool number to the NC device 18, determines whether all the necessary tools are included in the tool magazine, and if so, outputs a tool complete signal, and if the necessary tools are not included, the tool is displayed as NGItJIill. The automatic replenishment device replenishes the necessary tools, and when replenishment is complete, outputs the machining program number to the controller or NC device Z18 with a tool complete signal. If the program with the machining program number is in the NC device, machining preparation is completed, otherwise, the host computer The machining program is supplied from No. 19 and machining preparations are completed.

Example Embodiments of the present invention will be described below based on the drawings.

Front and rear (
On the sliding guide surface in the Z-axis direction, a carriage 4 having a sliding guide surface in the left and right (X-axis direction) on the upper surface is placed so as to be movable and positionable in the Y-axis direction under NC control. A table 5 is provided on the sliding guide surface in the axial direction so as to be movable and positionable with N C? A workpiece W is attached to the top via a jig 7.Furthermore, a sliding guide in the vertical (Y-axis) direction is provided on the front side of a column 8 fixed to the rear side of the upper surface of the bed 3. A spindle head 9 is provided on the surface so that it can be moved and positioned in the Y-axis direction by a ball screw (not shown) rotated by a servo motor 10 of N C'@? is mounted horizontally.

As shown in FIG. 2, the jig 7 fixed on the revolving table 6 has a publicly known identification means 14 attached or embedded therein, in which information such as a workpiece number, tool number, machining program number, etc. can be freely written and changed. A controller 16 with a manually or robotically operated reader 15 for reading the jig 7 is installed near the jig 7. The controller 16 is of an interactive type that is connected to the NC device 18 and sequentially outputs the contents of read signals to the NC device 18 in response to inquiry signals from the NC device 1B. And NCvtilt! The machine 18 is capable of executing a plurality of machining programs, and is further supplied with a large number of machining programs by the host computer 19. On the other hand, a tool storage 21 in which a plurality of tools are stored in a line is provided near the tool magazine 1, and the tool magazine 1 and the tool storage 21 are provided near this.
A known automatic tool replenishment device 22 is installed that automatically replaces tools under NC control. Further, the workpieces W are arranged and placed on a workpiece stand 24 that is brought in from the workpiece storage area 26 by an unmanned carrier at a predetermined position provided around the jig 7 on the turning table 6. .

This workpiece W is attached to a jig by a robot 25 controlled by NCflJJ.

In FIG. 3 of the operation flowchart, in step S1, the controller 16 reads the data stored in the identification means 14 by applying the reading device E15 to the identification means 14 attached to the jig 7. In step S2, the work number is output from the controller 16 to the NG device 21?8. In step S3, the corresponding workpiece W is attached to the jig 7 by the robot 25, and an attachment completion signal is sent to the NC device 1.
8 to the controller 16. In step S4, the tool number is output from the controller 16 to the NC device 18. In step S5, it is determined whether all the necessary tools are included in the tool magazine 1, and if so, a tool complete signal is output to the controller 16. If the necessary tools are not provided, the NC-controlled automatic tool replenishment device 22 replenishes the necessary tools from the tool storage 21 in step S6, and when the replenishment is completed, a tool completion signal is output to the controller. Step S
7, the machining program is transferred from the controller 16 to the NC
It is output to the device 18. In step S8, the NG installation
If there is a corresponding machining program in 1118, it is called and preparation for machining is completed. If there is no corresponding machining program in the NCVT device 1, preparation is completed after the machining program is supplied from the host computer 19 in step S9.

Effects As detailed above, the present invention provides a workpiece mounting jig with an identification means in which the workpiece number, tool number, and machining program number are stored, and reads the data stored in this identification means with a reading device and then reads the data stored in the identification means into the NC device. The system automatically outputs the following information in sequence, attaches the workpiece to the jig, attaches the necessary tools to the tool magazine, and calls the machining program in sequence, making it possible to significantly shorten setup time.
