1 is a block diagram for explaining an unmanned machine tool operating system capable of coping with a malfunction according to a preferred embodiment of the present invention.

1, the unmanned machine tool operating system according to the present invention collects signals output from a plurality of machine tools 100 and various sensors 110 to 150 installed on the machine tools 100 And a main server 300 capable of storing and processing data. At this time, the machine tools 100 and the main server 300 are connected to each other through a wired / wireless communication network 200 to exchange various signals and data. The wired / wireless communication network 200 includes a data collection device 160 mounted on the machine tool 100 and collecting signals from various sensors 110 to 150 of the machine tool 100, DAQ: Date Acquisition, 160) and the main server 300 through a wireless link. The set-top box may be used as the data collection device 160. Such an ultra high-speed network line plays an important role in transmitting a signal generated by the sensors 110 to 150 to the personal mobile device 500 as a final destination through the main server 300 at a high speed while minimizing time lag .

On the other hand, the machine tools 100 are provided with an alarm digital input / output sensor 110 therein. The digital input / output sensor 110 is an important means for achieving the object of the present invention. For example, when an alarm signal is generated due to an abnormality in the machine tool 100, even if an alarm signal is transmitted to an alarm lamp that can transmit an alarm signal to the outside, the light bulb in the alarm lamp fails, An unfortunate event that an administrator can not detect can occur. However, according to the present invention, the alarm signal can be transmitted to a separate digital input / output sensor 110 to reliably and repeatedly transmit the alarm signal to the personal mobile device 500 of the task manager. Therefore, even if the alarm lamp of the machine tool is malfunctioned, the operator can surely confirm the abnormality of the machine tool 100 through the digital input / output sensor 110 and solve the problem. This will be described later in detail with reference to FIG.

In addition, the machine tool 100 may further include a vibration sensor 120, a current sensor 130, a temperature sensor 140, and an IP camera 150 for relaying.

The vibration sensor 120 is also called an acceleration sensor, and is attached to a machine tool, specifically, a position adjacent to a cutting tool inside the CNC machine. Accordingly, the vibration sensor 120 collects the vibration data generated during the cutting process, and can process the collected Big Data in the main server 300 and transmit the Big Data to the personal mobile device 500. Therefore, when the vibration standard area for each machine tool and the machining conditions is selected and managed by the main server 300, the idling of the cutting tool, the breakage of the cutting tool, the stopping state of the cutting tool, the chattering phenomenon A phenomenon that is getting bigger and bigger) can be detected in real time. As a result, it is possible to improve the utilization rate of the machine tool and improve the machining accuracy.

The current sensor 130 is provided with a separate sensor for communicating with an external device in the power supply system of the CNC machine, thereby detecting an accurate state of power supplied to the driving unit of the machine tool. The data collected by the current sensor 130 can be transmitted to the personal mobile device 500 through the main server 300, like the vibration sensor. Through the big data collected by the current sensor 130, it is possible to predict or sense sudden machine stoppage and power cutoff that may occur during unmanned operation due to the overvoltage. Also, although power is supplied, it is possible to predict and confirm when machining stops, idling, and machining loads occur due to unstable power supply during machining.

The temperature sensor 140 is a sensor that is attached adjacent to a rotary tool and a workpiece to be actually machined, and is capable of collecting data by sensing a machining temperature of an ultra-high temperature occurring during cutting. In the CNC machine, when cutting is performed, the metal, which is the object to be cut, is thermally deformed. Failure to control the cutting temperature within an appropriate range in a CNC machine can result in warping and deformation of the workpiece, and may also result in the formation of a denatured layer that reduces the life of the workpiece while causing corrosion on the machined surface. Accordingly, an appropriate temperature management area is designated and monitored according to the combination of the cutting tool and the workpiece, and the result is transmitted to the personal mobile device 500 through the main server 300. The operator can check the overheating of the machining temperature, supply the cutting oil at the required time, cool the machining area to stabilize the machining quality, and prevent the machine stop of the CNC machine due to the instantaneous temperature rise.

The relay network camera (IP Camara) 150 allows a job manager to visually check the sealed space inside the CNC machine, which can not be confirmed by the signal sent from the above-mentioned sensor. That is, when the sensors 110 to 140 detect an abnormal signal, it is possible to check the state of the closed space in which the cutting process is performed through the relay network camera 150 in real time.

Meanwhile, the unmanned machine tool operating system according to the present invention further includes a personal mobile device 500 capable of transmitting and receiving data with the main server 300. Such a personal mobile device 500 may be a selected one of a smart phone, a tablet computer, and a notebook. At this time, the main server 300 and the personal mobile device 500 are preferably connected to each other wirelessly. Specifically, the main server 300 and the personal mobile device 500 can be interconnected using a TCP / IP (Transmission Control Protocol / Internet Protocol) have. To this end, the main server 300 and the personal mobile device 500 should be set up with a condition that TCP / IP is installed in advance and information can be exchanged with each other.

Referring to FIG. 2, when an abnormality is detected inside the machine tool, an alarm signal is generated 112 inside. At this time, even if the alarm signal is transmitted to the alarm lamp 114, if the light bulb in the alarm lamp 114 fails, the operator may not be able to detect the alarm signal. However, according to the present invention, when the alarm signal is generated, the alarm signal is transmitted to the alarm lamp 114 while the digital input / output sensor 110 separately installed on the line to which the alarm signal is transmitted detects the alarm signal. The signal transmitted to the digital input / output sensor 110 can reliably and repeatedly transmit the alarm signal to the personal mobile device of the worker via the main server by the operation of the machine tool operating system described in FIG. Therefore, even if the alarm lamp of the machine tool is malfunctioned, the operator can reliably check the presence or absence of the machine tool through the digital input / output sensor 110 and calibrate it.
