The radio handler according to the embodiments shown in FIGS. 4 and 5 has the same basic configuration as that of the radio handler used in the machine tool control system shown in FIG. I will focus on the parts.

As shown in FIG. 4, it is preferable to further include a sensor unit 141 in the wireless handler 100, and the sensor unit 141 detects that the direction of the wireless handler 100 is changed and xy coordinates on the screen. It is a component to change the direction of.

That is, when the user operates the wireless handler 100 while viewing the workpiece 10 loaded in the machine tool, as shown in FIG. 6, the screen display unit 140 of the workpiece 10 and the wireless handler 100 is first displayed. The coordinate system of) is set in the same way.

The user performs the machining operation on the workpiece 10 in a state as shown in FIG. 6, that is, while the machining operation is performed on one side of the workpiece 10 and the workpiece 10 is shown in FIG. 7. When the machining operation for the workpiece 10 is performed by moving to the other side of the xy coordinate system for the workpiece 10 and the xy coordinate system on the screen display unit 140 of the wireless handler 100 as shown in FIG. 7. Since the directions of the do not match each other, the operation of the user's wireless handler 100 becomes very inconvenient.

Therefore, in this case, the sensor unit 141 senses that the direction of the wireless handler 100 is changed, and as shown in FIG. 8, the xy coordinate system with respect to the workpiece 10 is determined in the direction of the xy coordinate system on the screen display unit 141. Switch the screen to match the direction of.

Therefore, the user can perform the machining operation very effectively and easily while alternating between the workpiece 10 and the screen display unit 140 on the wireless handler 100.

On the other hand, as shown in Figure 5 wireless handler 100 according to another embodiment of the present invention is configured to include a screen switching unit 142 instead of the sensor unit.

The direction of the xy coordinate system on the screen display unit 140 may be switched to a state as shown in FIG.

That is, the screen switching unit 142 functions to allow the user to manually switch the screen on the screen display unit 140.

Therefore, when the user performs the machining operation on the workpiece 10 in the state shown in FIG. 6, the user moves to the other side of the workpiece 10 to perform the machining operation on the workpiece 10. By operating the screen switching unit 142 in the state as shown in Figure 7 in the state shown in Figure 8 the direction of the xy coordinate system on the display unit 140 and the direction of the xy coordinate system with respect to the workpiece 10 The same can be reset manually.

On the other hand, with reference to Figures 9 and 10 will be described in more detail with respect to the control method of the machine tool control system according to an embodiment of the present invention.

9 is a control flowchart of a radio handler, and FIG. 10 is a diagram illustrating a control flowchart of an actuator, respectively.

As shown in FIG. 9, in the standby state (S100), the handler controller M (see FIG. 1) inputs an operation value by a user, that is, a reference value for setting a reference point of a workpiece, or a control value for controlling a machine tool. It is determined whether the input (S110).

When there is an input of a reference value or a control value, the handler control unit M (see Fig. 1) converts the input value into communication data (S111).

The communication data is converted into a specific radio signal, preferably a Bluetooth radio signal, by the first radio transceiver 130 (see FIG. 1) and transmitted to the actuator 200 (see FIG. 1) (S112).

Meanwhile, it is determined whether a specific radio signal (Bluetooth radio signal) is received from the actuator 200 (see FIG. 1) (S130).

When there is a reception of a specific radio signal from the actuator 200 (see FIG. 1), the handler control unit M (see FIG. 1) transmits an image corresponding to the received signal to the screen display unit 140 (see FIG. 1) and outputs an image. (S131).

If there is no reception of a specific radio signal from the actuator 200 (see FIG. 1), it is determined whether the operating range is out of operation (S140).

If it is determined that the moving out of range, it informs the user that the moving out of range (S141). In this case, the display may be displayed, a predetermined notification sound may be output, or both may be used.

If the deviation of the operating range is not received a specific signal from the actuator for a certain time is due to another error and proceeds to the subsequent step according to the error situation (S150). The control method for determining whether the operating range is out of the range will be described later.

Such a subsequent step may be, for example, to notify the user with a warning sound or to display an error situation on the screen display so as to induce the user to correct the error.

On the other hand, when the emergency signal is input by the user (S120), the information on the emergency signal is converted into a specific wireless signal and transmitted to the actuator (S121), and proceeds to the subsequent step according to the emergency signal generation (S122).

Such a subsequent step may be performed by, for example, notifying a user with a warning sound or displaying an emergency signal on the screen display, and receiving an information signal about the operating state of the machine tool from the actuator to receive the information of the current machine tool. It checks the operation status and the like, and if it is determined that the emergency situation may be released or not, it is displayed or notified.

Meanwhile, as shown in FIG. 10, in the standby state (S200), the actuator controller A (see FIG. 1) determines whether there is a reception of a specific radio signal, that is, a Bluetooth radio signal from the radio handler (S210).

If a specific radio signal is received from the radio handler, the received signal is analyzed and transmitted to the operation panel through the pulse generator (S220), whether to transmit to the operation panel through the control signal generator (S230), through the emergency signal generator It is determined whether to transmit to the operation panel (S240).

If the signal is transmitted to the operator panel through the pulse generator, the pulse generator transmits the pulse signal to the operator panel (S221).

If the signal is transmitted to the operation panel through the control signal generator, the control signal generator transmits the control signal to the operation panel (S231).

If the signal is transmitted to the operation panel through the emergency signal generator, the emergency signal generator transmits an emergency signal to the operation panel, and a subsequent step according to the emergency signal is generated (S241).

On the other hand, it is determined whether a signal relating to the operation or state of the machine tool is received from the operating panel of the machine tool (S250), and if the signal relating to the operation or state of the machine tool is received from the operating panel, the signal is converted into communication data. The conversion is made (S260).

The converted communication data is converted into a specific radio signal (Bluetooth radio signal) and transmitted to the radio handler (S261).

On the other hand, with reference to Figures 11 and 12 will be described a flow related to the communication range between the radio handler and the actuator, that is, the operation range determination and control in the machine tool control system according to an embodiment of the present invention.

11 and 12 are different from each other. First, the embodiment illustrated in FIG. 5 will be described.

11 is basically a method in which the actuator periodically sends a specific signal to the wireless handler and the wireless handler receiving the signal detects the strength of the signal and the like to determine whether the operating range is out of range.

As shown in FIG. 11, in a standby state (S10), a specific signal is periodically received from an actuator (S20), and the intensity of the received signal is compared with a preset setting value to determine whether the set value is smaller than the predetermined value. (S30).

If the strength of the received signal is greater than the set value, it is possible to display / notify that the normal operating range (S32).

If the intensity of the received signal is less than the set value to display / inform that the deviation of the operating range (S31), the user can be induced to move within the operating range.

On the other hand, the embodiment shown in Figure 12 is basically a method in which the radio handler periodically transmits a specific signal to the actuator and again detects the strength of the response signal from the actuator to the radio handler to determine whether the operating range is out of range.

As shown in FIG. 12, in a standby state (S40), the wireless handler transmits a specific signal periodically from the wireless handler to the actuator (S50), and determines whether the response signal from the actuator has been received by the wireless handler with respect to the transmitted signal. (S60).

If a response signal is received, it is determined whether the received signal is smaller than the preset value by comparing the strength of the received signal with a preset value (S61).

If the response signal is not received by indicating / notifying that the deviation of the operating range (S63), the user can be induced to move within the operating range.

On the other hand, when receiving a response signal, if the intensity of the received signal is more than the set value it is possible to display / notify that the normal operating range (S64).

If the intensity of the received signal is less than the set value to display / inform that the deviation of the operating range (S63), the user can be induced to move within the operating range.
