る。 Therefore, each tool is given a unique identification number, the identification number is read by some kind of reading means, and the current storage position of each tool is stored in memory.
A method is also used in which each tool can be stored randomly in each storage means, but in this case,
Although tools can be stored in all the storage means of each magazine, that is, the tool holding pocket, there are many problems such as installing a means to read the identification number and physically attaching the identification number to the tool by means such as a bar code. Not only does this have the drawbacks of requiring time and money, but it also requires a display means to show which magazine and which pocket each tool is currently stored in.
It also has the disadvantage of being structurally large-scale.
Furthermore, when an operator is setting up a tool, the operator must use the display to confirm which magazine and which pocket the tool he or she needs to attach or detach is stored in each pocket before proceeding with the operation, which is extremely tedious. The disadvantage is that there is a high possibility of mistakes occurring.

The tool 13 to be transferred from the tool magazine 7 to the replenishment tool magazine 20 in exchange for the tool 13 to be transferred from the replenishment tool magazine 20 to the tool magazine 7 is determined. As shown in FIG. 1a, the tool magazine 7 and the replenishment tool magazine 20 have six tool holding pockets 12.
A as a pocket symbol PK to distinguish between the two.
B, D, E, F, G and a, b, d, e, f, g
The tools 13 stored in each tool holding pocket 12 are set in a one-to-one correspondence. That is, tool holding pocket 1 with pocket symbols PK of A and a
Only the tools 13 with tool numbers TNO (the number written in the circle indicating the tool holding pocket 12 indicates the tool number TNO) 1 and 7 are stored in B.
and b, the tool holding pocket 12 has the tool number
Only tools 13 with TNO of 2 and 8 are stored. Similarly, tools 13 with tool numbers TNO 3 and 9 are stored in the tool holding pockets 12 of D and d, and
The tool holding pocket 12 of e and
Tools 13 with TNOs of 4 and 10 are stored. Also,
The tool holding pockets 12 of F and f are marked with tool numbers.
Tools 13 with TNOs 5 and 11 are stored, G and g
The tools 13 with tool numbers TNO 6 and 12 are stored in the tool holding pocket 12. Therefore, when the tool 13 to be replenished in the tool magazine 7 is specified by the machining program PRO, the tool 13 is returned from the tool magazine 7 to the replenishment tool magazine 20.
is immediately obvious from the one-to-one correspondence.

る。(g) Effects of the Invention As explained above, according to the present invention, the tools 13 stored in the replenishment tool magazine 20 and the tools 13 stored in the tool magazine 7 are arranged in a one-to-one correspondence. Make a combination and replace the tool 13 between the magazines 7 and 20 with the tool 1.
Since the exchange is performed only between the tools based on the combination of 3, it is possible to perform tool exchange work with the tools 13 stored in the tool storage means such as all the tool holding pockets 12 of each magazine 7 and 20. , each magazine 7, 20 can be used effectively. Furthermore, since tools are always replaced in a fixed combination, the number of tool holding pockets 12 in each magazine 7, 20 in which the combination of tools is stored is always constant, which not only facilitates the management of the tools 13, but also When an operator sets up the tools 13, if one of the pair of tools 13 is stored in the tool magazine 7, the other tool 13 is always stored in the corresponding tool holding pocket 12 of the replenishment tool magazine 20. Therefore, as long as the combination of tools 13 is known, the storage location of tools 13 can be immediately recognized, which has the advantage that work errors are less likely to occur. Furthermore, since there is no need to attach an identification number to each tool 13 or to provide means for reading the identification number or displaying the storage position of the tool, the configuration and structure of the numerically controlled machine tool are simplified and economical. This makes it possible to provide a method for exchanging tools.
