[0002]

In the molded product take-out machine, the moving position, moving distance, and purpose of the chuck are determined in accordance with the mold data regarding the size of the mold mounted on the molding machine and the type of the molded product. Various control data such as speed and acceleration data up to the position and time data are set, and the chuck is moved and controlled based on these various data to take out the molded product.

When the die to be mounted or the molded product to be taken out is changed, it is necessary to change the above-mentioned die data and control data, but it is necessary to change these data carelessly. To prevent this, only the specific operator who has the qualification (ability) to change the control data is allowed to change the control data. Then, in order to identify that the operator is a specific operator who is qualified to change the control data, it is obligatory to enter the password during the change work, and only when the correct password is entered, the control data can be changed. Is enabled.

However, the management of change of the control data by the password is promptly performed when the data can be changed by another operator who is informed of the password or when the password is forgotten even by a specific operator. The data could not be changed, and the work efficiency of changing the data was poor.
Furthermore, when the password is changed, it is necessary to inform the changed password that the password management becomes complicated.

The present invention has been invented in order to solve the above-mentioned conventional drawbacks, and its problem is to reliably recognize only a specific operator who can change control data. It is an object of the present invention to provide a method for changing control data of a molded product take-out machine, which can efficiently change control data.

[0006]

According to the present invention, a chuck for holding a molded product is moved between a mold of a molding machine and a release position of the molded product based on control data to take out the molded product. The machine is characterized in that the control data can be changed only when the operator is recognized as a specific operator registered in advance when the control data is changed.

The above-mentioned traveling unit 9 and front-rear unit 1
1 and the upper and lower sliders 15 are servo motors 19 and 21 such as AC servo motors and DC servo motors that can be numerically controlled.
・ Movement is controlled in each direction by 23.

Various control data such as control data relating to the moving direction, distance, speed and position of the chuck 13 and molding data relating to data of a mold mounted on the molding machine are set and input by the operation box 25. Operation box 2
5, a mode changeover switch 25a for inputting various control data, a numerical key 25b, and a display member 25c such as an LCD for displaying the input data are arranged.

Further, in the operation box 25, an operator recognition device 27 such as a fingerprint reading device, a retina reading device, a voice print input device, or the like.
Is provided. When the operator recognition device 27 is a fingerprint reading device, the operator's fingerprint is read as binary data by an optical scanning device, a digital video camera, a digital camera, or the like.

A fingerprint recognition device will be described as an example of the operator recognition device 27. In FIG. 3, a CPU 29 of the operator recognition device 27 is connected to a program memory 31 such as ROM, HDD, DVD and a working memory 33 such as RAM. Is
The program memory 31 has a fingerprint recognition program data, and the working memory 33 has a specific person registration area 33a for storing verification fingerprint parameters of specific persons registered as persons who are qualified to change control data. There is.
The collation fingerprint parameter stored in the specific person registration area 33a is registered together with the data regarding the control data change qualification (a plurality of levels) possessed by the specific person.

That is, as the collation fingerprint parameter stored in the specific person registration area 33a, for example, in the case of an operator who is qualified to change all the control data including the mold data, it is set to level 1, and the mold is also set. In the case of an operator who is qualified to change the control data excluding the data, it is stored for each level according to the importance of the control data, such as level 2.

The working memory 33 is a read buffer area 33b.
have. The reading buffer area 33b stores parameter data in which the fingerprint of the operator read by the fingerprint reading device 35 is parameterized. A fingerprint reader 35 is connected to the CPU 29 via an I / O 37. The fingerprint reading device 35 is embodied by a digital imaging device such as a scanner, a digital video camera, a digital camera, which is an optical scanning device that optically reads a fingerprint.

The CPU 29 outputs the fingerprint data of the operator read by the fingerprint reading device 35 to the parameter circuit 36, samples a specific portion (a plurality of points) in the fingerprint data, parameterizes it, and then stores it in the reading buffer area 33b. .

The CPU 29 specifies the operator by comparing and collating the collation fingerprint parameter stored in the specific person registration area 33a with the fingerprint parameter data of the operator stored in the reading buffer area 33b, and determines the operator according to the level of the operator. The change permission signal of the control data is output to the control device 38 of the molded product unloading machine 1 to enable the data change of the control data of the level.

Next, the operation of changing the control data will be described.
First, the fingerprint registration process of the operator will be described with reference to FIGS.
At step 41, it is determined whether or not the changeover switch 25a of the operation box 25 is switched to the fingerprint registration mode. Since the operator is now switching the operator recognition device 27 to the registration mode with the changeover switch 25a in order to register his / her fingerprint, step 41 is YES.
Then, in step 42, the operator's fingerprint is read and the binarized data is output to the CPU 29, and then step 4
The collated fingerprint parameter data is created by sampling and parameterizing a specific portion in the binarized fingerprint data according to 3.

Next, in step 44, the collation fingerprint parameter data is stored in the specific person registration area 33a together with the operator level. As a method of registering the collation fingerprint parameter together with the identification data indicating the level, the specific person registration area 3
3A, areas for each level are provided, and collation fingerprint parameter data is stored in each area, or a level discrimination flag is set in each collation fingerprint parameter data.

With the above processing, the operator's fingerprint registration processing ends. Next, an operator recognition process when changing various control data such as mold data and control data will be described.

Now, after registering the fingerprint of the operator, the operation box 2
Assuming that the changeover switch 25a of No. 5 is switched to the operator recognition mode, step 41 becomes NO, and then the operator's fingerprint is read by the operator recognition device 27 in step 45 and the binarized fingerprint data is read. Output to the CPU 29.

Next, the binary fingerprint data input at step 46 is output to the parameter circuit 36, and the parameter circuit 36 samples and parameterizes a specific portion in the binary fingerprint data to read the read fingerprint. The parameter data is created and stored in the read buffer area 33b.

Next, in step 47, the read fingerprint parameter data stored in the read buffer area 33b is compared with the collated fingerprint parameter data registered in the specific person registration area 33a, and in step 48, the data in the read buffer area 33b is stored. It is determined whether any of the data registered in the specific person registration area 33a matches. If they do not match, an alarm signal is output in step 49 to inform the operator that the control data cannot be changed.

On the other hand, if the data in the read buffer area 33b matches the data registered in the specific person registration area 33a and step 48 is YES, the collation fingerprint parameter data registered in the specific person registration area 33a in step 50 is used. The control data change permission signal of the specified level is output to the control device 38 of the molded product unloading machine 1 together with the collation fingerprint parameter data based on the attached identification data.

That is, when the level identification data attached to the collation fingerprint parameter data is level 1, the specific person who is going to change the control data is qualified to change all the control data including the mold data. Therefore, since it has the qualification to change the permission signal for changing all control data, and in the case of level 2, it has the qualification to change other control data except mold data. Output a permission signal to permit the change of the control data.

Embodiment 2 In this embodiment, whether or not an operator who intends to change control data is a pre-registered specific operator is determined by the retina pattern of the operator. That is, the retina pattern of the specific operator is registered in advance, and when the control data is changed, the retina pattern of the operator is compared and collated with the retina pattern of the specific operator registered in advance, and the control is performed only when they match. Enables data modification operations.

Embodiment 3 In this embodiment, whether or not the operator who intends to change the control data is a pre-registered specific operator is determined by the voice pattern of the operator. That is, the voice pattern of the specific operator is registered in advance, and when the control data is changed, the voice pattern of the operator is compared with the voice pattern of the specific operator registered in advance, and the control is performed only when they match. Enables data modification operations.
