Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] <Industrial Application Field> The present invention relates to a tooling tower equipped with a mold identification device.

(Prior art) Various machine tools that use molds, especially punch presses, require a tooling tower to store and manage the molds. Various types of devices are used, ranging from automatic devices that can automatically take out a predetermined mold by inputting a station number or mold number manually.

(Problem to be solved by the invention) However, in these conventional tooling towers, even if the tooling tower is automatic, the station number for mounting the mold corresponds to the number of the mounting mold and is managed using table data. However, the following problems remained:

(2) If the mold is replaced manually and the mold number is entered incorrectly, the table data will be stored incorrectly and the mold will be lost in the tower.

■ If the table data is incorrect, the robot, etc. may accidentally take out another mold, and the machine to which the mold is attached (for example, a ret punch press)
This will cause problems.

■ With conventional touring towers, if you want to check the mold installed at a given station, the mold number is displayed as is, corresponding to the station number.
Confirmation work is required to determine its authenticity.

Therefore, the object of this invention is to provide a tooling tower that improves these problems, improves the reliability of table data, allows easy confirmation of molds when installed, and allows reliable money management. .

The signal S1 is a voltage signal having potential changes between the end surface of the punch 27 and the mold holder and between the end surface and the edge of the die 29.

The mold management control device 5 has a mold management section 83 inside. The management section 83 is connected to the NC device 3, the key group 5a, and the signal processing circuit of the mold identification device 21. The control device 5 also includes a mold data storage section 85 connected to the mold management section 83, a tower control section 87, and a robot control section 89.

The mold management data storage unit 85 stores, as table data, a mold number Ti set at the station in correspondence with the station number TTSi of the tooling tower 9. Additionally, it also has shape data indicating the shape of each mold for all molds.

The processing performed by the mold management section 83 is as follows.

The table data is updated in response to the mold setting signal @5ETs from the key group 5a.

In response to a display command DS from the key group 5a, all or part of the table data is displayed on the CRT 5a according to the command. Further, the shape of the mold attached to a predetermined station TTSi can be imaged by the mold identification device 21 and then displayed.

In response to the die change command TC8 from the NC device 3, first, a predetermined station MTS of the turret punch press 1 is sent.
The robot controller 89 is instructed to take out a predetermined mold from i. The robot control unit 89 controls the robot 7 to take out a mold from a predetermined station MTSi of the turret punch press 1. The robot 7 transports the removed mold to a predetermined station T of the tooling tower 9.
Store in TSi. For this purpose, the tower control section 87 is activated at a predetermined timing, and the shaft 25 of the touring tower 9 is
The motor MI is driven so that the empty station TTSi signal comes to the take-out port.

On the other hand, in connection with these operations, the mold management device 83 searches for molds required by the turret punch press 1.
The table data in the mold management data storage section 85 is referred to to detect which station of the tower a predetermined mold is attached to.

Therefore, in this example, an identification command is output to the mold identification device 21 in order to confirm whether a desired mold is truly attached to the station position searched by the table data.

Based on the instruction, the mold identification bag e121 confirms the shape of the mold at the station position detected by the table data in the manner shown in FIGS. 8 and 9, and identifies this shape with the shape data. The mold is compared with the specified shape to identify whether it is a regular mold or not.

If the mold is a regular mold, the mold management section 83 attaches the mold attached to the station to a predetermined station of the turret punch press 1 via the tower control section 87 and the robot control section 89. . Further, if the mold is not a regular mold, an alarm is outputted via the CRT 5a indicating that the regular mold is not attached to a predetermined station TTSi of the tower. A buzzer may also sound at the same time.

As described above, in this example, since the mold identification is performed by the mold exchange command TC8, there is no possibility of automatically exchanging different types of molds by mistake.

In the above example, the mold identification device 21 is operated at the time of mold replacement, but a timer is provided and the device 21 is operated at predetermined time intervals, for example during the day and at night, for all stations of the tower 9. It is also possible to sequentially identify the molds, check whether the table data is correctly written, and notify the portions where there are errors. If an error is reported, it is sufficient to check only that station and operate the key group 5b to correct the table data to the correct one.

As described above, according to this embodiment, the shape of the mold can be recognized by scanning the optical fiber array arranged on a line in accordance with the end face of the mold, and the predetermined position of the tower 9 can be recognized from the recognized mold shape. Since the molds attached to the stations can be identified, the table data can always be adjusted to regular data, and the molds of the tooling tower 9 can be managed reliably.
