Description

Machine tool control panel and its control method

[0001] The present invention relates to a control panel including a control panel of a machine tool and a method for controlling the control panel, and more specifically, to a structure of a control panel and a method for controlling the same that displays the operation details of a simple actuator connected to the control panel on the control panel.

[0002] Machine tools have a feed axis system that moves the table, column, tool holder, etc., in the left-right (X-axis), up-down (Z-axis), and forward-backward (Y-axis) directions, and a rotation axis system that rotates the spindle, rotary table, etc., at high speed or divides the angle around the rotation axis.

[0003] A machine tool is equipped with a control panel on one side of the machine tool body to allow an operator to manipulate each operating part of the machine tool. Generally, the control panel operates the feed axis system and the rotary axis system and consists of an input section comprising a touch screen, buttons, or a combination thereof, and a display section that displays the input results from the input section or information provided from the machine tool's control target parts, NC, etc.

[0004] Furthermore, these control panels are typically installed immovably on one side or at a specific location of the machine tool. As the control panel is fixed in one position in this manner, in the case of large machine tools, the distance between the control panel and the machining area is considerable, making it difficult for the operator to observe both the control panel and the workpiece or tool in the machining area from a single vantage point.

[0005] Therefore, when setting a workpiece in the machining area, the operator must move back and forth between the control panel and the machining area to operate the feed axis system, which causes inconvenience. In particular, when operating the feed axis system while observing the movement of the feed axis system in the machining area and the workpiece or tool, the operator cannot properly observe the machining area at a distance while operating the control panel from the front. Consequently, accidents involving collisions with tools or workpieces may occur due to the movement of the feed axis system caused by operational errors, and safety accidents may even occur that injure other workers performing setting work in the machining area.

[0006] To prevent such inconvenience and safety accidents, a simple operating device (generally called a Handle) connected to the control panel is additionally provided so that the operator can carry it and move within a certain range to operate the control panel of the machine tool.

[0007] These simple operating devices are typically connected to the control panel via wired or wireless means, transmitting operation commands to the control panel to control the target part of the machine tool.

[0008] In addition, these simplified controls are typically designed to be small and lightweight so that an operator can move near the machining area of ​​the machine tool to operate them, and are configured to include only some basic input functions of the control panel.

[0009] As such, since the functions of the simplified operator are simplified and it cannot be equipped with a screen display of the same size as the control panel, when an operator holds the simplified operator and approaches a machining area separated from the control panel to perform operations, the operator must move forward to the control panel to verify the details of the operation performed via the simplified operator, and furthermore, it becomes impossible to check various information, such as information provided by the NC, displayed on the control panel's screen display.

[0010] As a result, workers carrying a simplified control device may misoperate the axis to be transferred (X, Y, Z) or the direction of transfer (+, -) depending on their position or standing direction, which increases the risk of accidents.

[0011] Meanwhile, in the prior art of this field, Patent Document 1 (the numbers in parentheses below are drawing symbols of Patent Document 1) describes a device for manually inputting setting data for each axis of a machine tool and transmitting it to a numerical control unit, comprising a transmitting unit (30) that inputs the setting data through an axis selection switch (31), a feed ratio selection switch (32), and a manual pulse generator (35) and transmits it wirelessly through a high-frequency wireless module (45), and a receiving unit (50) that receives the wirelessly transmitted data through a high-frequency wireless module (55) and transmits it to a numerical control unit of the machine tool through a relay driving module (62) and a buffer (64). The transmitting unit (30) is equipped with an MPU (41) that generates data including unique code information for each device, and the receiving unit (50) is equipped with an MPU (51) that selects the received data and transmits the data to a device corresponding to each function.

[0012] In addition, Patent Document 2 discloses a machine tool control system configured to control a control panel that controls the operation of a machine tool, comprising: an actuator connected to the control panel and configured to exchange data with the control panel and convert specific data into a specific wireless signal to enable wireless transmission and reception; and a wireless handler that controls the control panel and displays the operating status of the machine tool by transmitting and receiving a specific wireless signal to the actuator, wherein the wireless handler and the actuator communicate bidirectionally wirelessly and the actuator and the control panel communicate bidirectionally.

[0013] In addition, Patent Document 3 relates to a wireless handler for a machine tool, comprising an operating unit installed on the outer surface of a case, a signal processing unit that receives and processes an operating signal from the operating unit, and a wireless transmission unit that transmits information processed by the signal processing unit to a receiver of the machine tool.

[0014] In addition, Patent Document 4 describes a wireless manual pulse generation control device and method for simultaneous multi-axis control of a machine tool, wherein the manual pulse generation device is configured with a transmitting unit capable of wireless communication and a receiving unit, and the transmitting unit is configured with an axis selection switch, a feed ratio selection switch, and a manual pulse generator as an operating module to enable simultaneous multi-axis control, and multiple of these are provided in the transmitting unit to transmit control signals for multiple axes so that multiple axes of the machine tool can be operated simultaneously.

[0015] However, the aforementioned patent documents all relate to the simple operating device itself, and as previously pointed out, they overlook the problems that may arise due to the distance between the simple operating device and the control panel.

[0050] Hereinafter, preferred embodiments of the present invention will be described with reference to FIGS. 1 to 5.

[0053] In the following embodiments, unless specifically limited otherwise, the term "shaft system" includes feed shaft systems and rotation shaft systems.

[0054] The control panel (20) is fixed integrally to the body of the machine tool (10) or installed so as to be pivotable.

[0055] In addition, on one side of the control panel (20), a simple operating device (generally also called a Handle Controller) (30) is installed, which is connected to the control panel (20) by a wire of a certain length so that a worker can carry it and move it within a certain distance range, and is equipped with an input means that can issue some of the commands for controlling the machine tool (10) from the control panel (20).

[0056] Meanwhile, in another embodiment, the control panel (20) and the simple control device (30) may be connected via wireless communication by installing a wireless communication module in each.

[0064] Additionally, on one side of the front of the control panel (20), a display module (21) is installed to indicate the activation state of the simple operator (30) when the enable button (25) selects the use of the simple operator (30), and to display the signal or information so that the operator can recognize it when at least one operation signal or information is provided from the axis selection switch (31), magnification selection switch (32), or transfer dial (33) of the simple operator (30).

[0065] Additionally, the control panel (20) includes a screen display unit (22) on another side of the front that displays detailed information provided from the simple operating device (30), information input from the input unit (24), and information received from the numerical control device of the machine tool (10).

[0066] Additionally, the control panel (20) determines the type and method of displaying information to be displayed on the display module (21) based on signals or information provided by the simple operating device (30), drives the display module (21), and controls the output of the information provided by the simple operating device (30), input information provided by the input unit (24), information provided by the numerical control device of the machine tool (10), or results processed through internal calculations to the screen display unit (22).

[0067] Meanwhile, a cable (35) is installed between the above-mentioned simple operator (30) and the control panel (20) to transmit a signal or information selected from the axis selection switch (31), magnification selection switch (32), transfer dial (33), safety switch (34), etc. of the simple operator (30) to the control unit (23) of the control panel (20).

[0068] FIG. 3 is a configuration diagram showing another embodiment of the present invention in which a simple operating device is placed on one side of the front of the control panel.

[0069] Meanwhile, as shown in FIG. 3 in another embodiment, a simple operating device (30) including the axis selection switch (31), magnification selection switch (32), transfer dial (33), safety switch (34), etc. may be placed on one side of the front of the control panel (20).

[0070] At this time, the cable (35) connecting the simple operating device (30) and the control panel (20) can be replaced with the internal circuit of the control panel (20), the safety switch (34) for preventing misoperation is removed, and the transfer dial (33) connected in series with the safety switch (34) is provided independently to the control panel (20).

In this case, the cable (35) connecting the simple operating device (30) and the control panel (20) can also be replaced with the internal circuit of the control panel (20).

[0072] Meanwhile, in another embodiment, the control panel (20) may have a screen display unit (22) installed on the front, which may display detailed information provided from the simple operating device (30), information input from the input unit (24), and information received from the numerical control device of the machine tool (10) by mounting a transparent display panel on the glass window of the door (not shown) of the machine tool. Such a transparent display can be implemented using a known transparent organic light-emitting diode (OLED), a transparent LCD display, or a transparent LED panel.

[0073]

[0074] Meanwhile, FIG. 4 is an example diagram showing an operation example of a control panel (20) display module (21) as an embodiment of the present invention.

[0075] Referring to FIG. 4, the display module (21) placed on the control panel (20) is positioned on one side of the upper front of the control panel (20) and is configured in a roughly rectangular shape such that when the enable button (25) of the input section (24) is selected, the brightness is activated and visibility is increased.
