[0003] [Patent Document 1] JP 2000-330615 A ​​(paragraph 0017, Figure 4) Summary of the Invention [Problem to be solved by the invention]

[0004] In the grinding machine described above, information about the left and right wheel heads is displayed on the HMI, and information about the left or right wheel head is displayed depending on the operation of the selection button labeled "L" or "R." However, if the left and right wheel heads have the same or similar configuration, the information screen for the left wheel head and the information screen for the right wheel head will have similar screen configurations. As a result, there is a risk that the user will mistakenly recognize that the information and operation buttons displayed on the display screen refer to one of the two wheel heads. This could lead to the user accidentally operating an unintended wheel head, for example, operating the right wheel head when they intended to operate the left wheel head.

[0005] The present disclosure has been made in consideration of the above-mentioned problems, and aims to provide a machine tool that can reduce the occurrence of erroneous operations on processing devices when operations on multiple processing devices are accepted by a display operation device. [Means for solving the problem]

[0006] In order to solve the above problems, the present disclosure provides a system including a first processing device that performs processing on a workpiece, a second processing device that performs processing on a workpiece and is arranged alongside the first processing device, a display operation device, and a control device that controls the first processing device and the second processing device and displays information relating to the first processing device and the second processing device on the display operation device, wherein the control device displays a first operation unit and a switching button on the display operation device, the first operation unit is an operation unit that accepts operation instructions for the first processing device, and the switching button is a button that switches from a state in which the first operation unit is displayed on the display operation device to a state in which a second operation unit that accepts operation instructions for the second processing device is displayed on the display operation device, and the control device displays the first operation unit and the switching button on the display operation device in the direction and order in which the first processing device and the second processing device are arranged. a first area displaying the first operation unit is displayed surrounded by a first color, a second area displaying the second operation unit is displayed surrounded by a second color different from the first color, and the switching button is displayed surrounded by the second color; a first status display unit displaying a status of the first processing device and a second status display unit displaying a status of the second processing device can be displayed on the display operation device; the first status display unit and the second status display unit are displayed in both a status displaying the first operation unit and a status displaying the second operation unit; and the first status display unit and the second status display unit are displayed on the display operation device in a direction and order in which the first processing device and the second processing device are arranged. Machine tools. [Effects of the Invention]

[0007] According to the machine tool of the present disclosure, the first operation unit that accepts operation instructions for the first processing device and the switch button that switches to a state where operation instructions for the second processing device are accepted are displayed in the same direction and order as the actual arrangement of the first and second processing devices on the machine tool. This allows a user looking at the display operation device to visually associate and recognize the first processing device with the first operation unit, and the second processing device with the switch button. This reduces the occurrence of erroneous operation using the first operation unit or the second operation unit. [Brief explanation of the drawings]

[0009] An embodiment of the machine tool of the present application will be described in detail below with reference to the drawings. FIG. 1 shows a perspective view of machine tool 1 of this embodiment as seen from the front. FIG. 2 shows a block diagram of machine tool 1. In the following description, the direction of machine tool 1 as seen from the front, as shown in FIG. 1, will be used as a reference, and the direction across the machine width that is parallel to the installation surface of the device will be referred to as the left-right direction, the direction parallel to the installation surface of the device and perpendicular to the left-right direction will be referred to as the front-rear direction, and the direction perpendicular to the left-right direction and the front-rear direction will be referred to as the up-down direction. In the following description, the letter "L" will generally be added to the reference numerals relating to devices located on the left side of machine tool 1, and the letter "R" will be added to the reference numerals relating to devices located on the right side.

[0010] (Configuration of machine tool 1) 1 and 2, the front of machine tool 1 is covered by equipment cover 2, and an operation panel 3 is provided in the center of the front of the machine. Equipment cover 2 has a left front door 5L and a right front door 5R on both the left and right sides of the operation panel 3. The left and right front doors 5L, 5R are, for example, sliding doors, and opening the doors allows access to the machining space behind the doors.

[0011] As shown in FIG. 2, in addition to the operation panel 3, the machine tool 1 includes a left-side machining device 11L, a right-side machining device 11R, a workpiece transport device 14, and a control device 15. A machining space for the left-side machining device 11L and the left-side machining device 11R is provided behind the left-side front door 5L. The left-side machining device 11L is, for example, a turret-type lathe and includes a left-side spindle unit 12L and a left-side turret 13L. The left-side spindle unit 12L includes, for example, multiple jaws (child jaws and master jaws) for chucking a workpiece, gripping the workpiece, and rotating it around its axis. The left-side turret 13L has a tool post to which multiple tools (rotary tools and cutting tools) can be attached and performs tool indexing. The left-side turret 13L performs machining (such as cutting or drilling) on ​​the workpiece gripped by the left-side spindle unit 12L using the indexed tools. A user can check the machining status of the workpiece or replace worn tools through the left-side front door 5L.

[0012] Additionally, a machining space for the right-side machining device 11R and the right-side machining device 11R is provided behind the right-side front door 5R. Therefore, when the machine tool 1 is viewed from the front (front), the left-side front door 5L (left-side machining device 11L), the control panel 3, and the right-side front door 5R (right-side machining device 11R) are arranged in this order from left to right. The right-side machining device 11R has the same configuration as the left-side machining device 11L. Therefore, in the description of the right-side machining device 11R, the description of the same components as the left-side machining device 11L will be omitted. The right-side machining device 11R is equipped with a right-side spindle unit 12R and a right-side turret 13R. The spindle of the right-side spindle unit 12R is opposed (faces) to the spindle of the left-side spindle unit 12L of the left-side machining device 11L, for example, in the left-right direction. Therefore, the left-side and right-side machining devices 11L, 11R are what is known as an opposed-two-spindle lathe. The right-side machining device 11R performs machining on a workpiece gripped by the right-side spindle device 12R using a tool on the right-side turret 13R. The right-side machining device 11R may perform machining on a workpiece different from that of the left-side machining device 11L, or may perform machining before or after the machining of the left-side machining device 11L.

[0013] In this disclosure, the term "same configuration" as described above refers to a configuration that allows the same type of device or tool to be attached, even if the orientation of the spindle or tool is different (even if they are symmetrical). Furthermore, the right-side machining device 11R does not have to have the same configuration as the left-side machining device 11L. For example, at least one of the left-side machining device 11L and the right-side machining device 11R may be another type of machining device, such as a machining center. Furthermore, the machine tool 1 may be equipped with a machining center in addition to the left-side machining device 11L and the right-side machining device 11R. In other words, the machine tool 1 may be equipped with three or more machining devices.

[0014] The workpiece transport device 14 is, for example, a gantry-type transport device, and transfers workpieces between the left and right processing devices 11L, 11R, and upstream and downstream machine tools. The workpiece transport device 14 is attached to the top of the machine tool 1, and is capable of moving a chuck (not shown) that grips the workpiece in the left-right and up-down directions. The operation panel 3 is provided in the center of the front of the device cover 2 and is equipped with a touch panel 3A and operation switches 3B (see FIG. 2). The operation panel 3 receives operation inputs from the user via the touch panel 3A and operation switches 3B and outputs signals corresponding to the received operation inputs to the control device 15. The operation panel 3 also changes the display content of the touch panel 3A under the control of the control device 15. Various types of touch panels, such as a capacitive touch panel and a resistive touch panel, can be used as the touch panel 3A. The touch panel 3A is an example of a display / operation device of the present application. The display and operation device of the present application is not limited to a touch panel, and may be configured to include a display screen such as a liquid crystal display or an organic EL display, and push buttons or hard keys for selecting items displayed on the display screen (first operation unit buttons and switching buttons of the present disclosure). In other words, the display and operation device may be configured so that the user operates hard keys or the like provided separately from the display screen while looking at the display screen.

[0015] 2, the control device 15 of the machine tool 1 is a processing device that includes a CPU 15A and a memory 15B and is primarily a computer. The memory 15B includes, for example, RAM, ROM, flash memory, etc. The control device 15 is electrically connected to each device (such as the left-side machining device 11L) and is capable of controlling each device. Various control programs PG are stored in the memory 15B. The control programs PG include, for example, an NC program that controls the operation of each of the left-side and right-side machining devices 11L, 11R when machining a workpiece, and a program that controls the operation of the workpiece transport device 14.

[0016] The control device 15 controls the operations of the left and right processing devices 11L, 11R, and displays information related to the left and right processing devices 11L, 11R on the touch panel 3A. Image data DT is stored in the memory 15B. The image data DT is data for an image to be displayed on the touch panel 3A, such as data for an operation screen that accepts operation inputs to the left spindle device 12L. The control device 15 reads out an image corresponding to an operation input to the touch panel 3A or the operation switch 3B from the image data DT and displays it on the touch panel 3A.

[0017] (Changes to the configuration and display of the operation screen) Next, the configuration of the operation screen displayed on the touch panel 3A and the process of changing the display of the operation screen will be described. FIG. 3 is an example of a display screen displayed on the touch panel 3A, showing an operation screen 21 displaying an operation button 28L for receiving operation instructions for the left spindle unit 12L. As shown in FIG. 3, the operation screen 21 displays a main body status display section 23, status display sections 25L and 25R, an operation section display area 27L, a right switching button 29R, etc. The control device 15 displays the operation screen 21 on the touch panel 3A in response to a predetermined operation input to the touch panel 3A, etc. The predetermined operation input here refers to, for example, an operation input in accordance with an operation procedure for displaying the operation button 28L on the touch panel 3A. Note that the screen configurations shown in FIG. 3 and FIG. 4, which will be described later, are merely examples and can be changed as appropriate depending on the device configuration of the machine tool 1, etc.

[0018] The main body status display unit 23 is displayed at the top of the operation screen 21, and displays multiple pieces of information and operation buttons. The control device 15 accepts operation instructions to change the operation of the left-side processing device 11L, the right-side processing device 11R, the workpiece transport device 14, etc., via the touch panel 3A. For example, in any state in which the control device 15 displays a screen for accepting operation instructions for each device, such as the left-side processing device 11L, on the touch panel 3A, the control device 15 displays information that should always be notified to the user as information about the machine tool 1 and operation buttons for operations that should be accepted on the main body status display unit 23. In the example shown in FIG. 3, the main body status display unit 23 displays a workpiece number button 31 that displays a workpiece number indicating the type (product number) of the workpiece to be processed. The control device 15 accepts changes to the workpiece number in response to an operation input to the workpiece number button 31. The main body status display unit 23 also displays warning information 33 that indicates the occurrence of an error or malfunction, door information 34 that indicates whether the left and right front doors 5L, 5R are open or closed, etc. This allows information that is frequently checked by the user, such as workpiece numbers and warnings, and operation buttons that are frequently executed by the user to be constantly displayed on the main body status display unit 23. Note that the control device 15 does not need to constantly display the main body status display unit 23, and may change the display content of the main body status display unit 23 in accordance with the display of the operation screens of the left-side processing device 11L, the right-side processing device 11R, and the workpiece transport device 14.

[0019] The status display units 25L and 25R are displayed below the main body status display unit 23 and are arranged side by side in the left-right direction. Each of the status display units 25L and 25R has a rectangular shape that is elongated in the left-right direction and is the same size. The status display unit 25L is surrounded by, for example, red lines. The status display unit 25R is surrounded by blue lines. Therefore, the control device 15 displays the status display unit 25L of the left-side processing device 11L surrounded by a red line on the left side, and the status display unit 25R of the right-side processing device 11R surrounded by a blue line on the right side. In FIG. 3, for ease of explanation, the blue outer frame of the status display unit 25R is shown with a dashed line. The same applies to the right switching button 29R, which will be described later.

[0020] The status display section 25L displays information about the status of the left-side machining unit 11L. For example, the status display section 25L displays chuck status information 37L, which indicates whether the left-side spindle unit 12L is chucking (clamping) a workpiece or releasing the clamping. The status display section 25L also displays mode information 38L, which displays information about the NC mode (the currently selected NC mode) of the left-side machining unit 11L. The NC mode here refers to, for example, an NC control mode, such as an automatic operation mode in which an NC program is loaded and automatically executed in sequence, a manual operation mode in which a user manually operates the NC program, an MDI operation mode in which an NC program is executed line by line, or an edit mode in which the NC program can be edited. The status display section 25L also displays turret number information 39L, which indicates the holder number of the tool (used for machining) indexed by the left-side turret 13L.

[0021] The status display section 25R is displayed to the right of the status display section 25L. The status display section 25R displays information about the status of the right-side machining device 11R, and displays the same information items as the status display section 25L. Therefore, in explaining the status display section 25R, explanations of the same configuration as the status display section 25L will be omitted as appropriate. The status display section 25R displays chuck status information 37R of the right-side spindle device 12R, mode information 38R related to the NC mode of the right-side machining device 11R, and turret number information 39R of the right-side turret 13R.

[0022] Furthermore, the operation unit display area 27L and the right switching button 29R are displayed below the status display areas 25L and 25R. The operation unit display area 27L is a rectangular area surrounded by an area frame 26L. The area frame 26L is, for example, a straight-line frame that is red (an example of the first color of the present disclosure) and is a rectangular frame that is long in the left-right direction. A plurality of operation buttons 28L and the like are arranged within the operation unit display area 27L surrounded by the area frame 26L. The letter "L" 30L indicating the left side is displayed in the upper left corner of the area frame 26L and the operation unit display area 27L. The letter 30L is, for example, displayed as a white L on a red background.

[0023] The right switching button 29R is displayed on the right side of the operation unit display area 27L and has a substantially square shape. The right switching button 29R is, for example, surrounded by a blue line (an example of the second color in the present disclosure). The letter "R" 30R, indicating the right side, is displayed in the upper right corner of the right switching button 29R. The letter 30R is, for example, displayed as a white R on a blue background. The right switching button 29R is a button that switches from a state in which the operation buttons 28L are displayed on the touch panel 3A to a state in which the operation buttons 28L (operation unit display area 27L) that accept operation instructions for the right-side processing device 11R shown in FIG. 4 are displayed on the touch panel 3A. The control device 15 displays the operation buttons 28L (operation unit display area 27L) and the right switching button 29R in the direction (left-right direction in this embodiment) and order (left, right) in which the left and right processing devices 11L, 11R are arranged.

[0024] Therefore, the control device 15 displays the operation button 28L for operating the left-side processing device 11L on the left side and the right switching button 29R for switching to operation of the right-side processing device 11R on the right side, so as to be arranged in the same manner as the arrangement of the actual processing devices of the machine tool 1. Furthermore, the control device 15 displays the operation unit display area 27L and the right switching button 29R in the same way as the status display areas 25L and 25R: the operation unit display area 27L for receiving operation instructions for the left-side processing device 11L is surrounded by a red area frame 26L, and the right switching button 29R for switching to operation of the right-side processing device 11R is surrounded by a blue frame.

[0025] Further, below the operation unit display area 27L, a plurality of selection buttons 41 are displayed. Each of the plurality of selection buttons 41 is a button for changing the device that is the target of operation of the operation button 28L, that is, for changing the type of operation button 28L displayed in the operation unit display area 27L. For example, the characters "spindle," "jig," "slide turret," "door blow," "rotary tool," and "peripheral device" are displayed on each of the plurality of selection buttons 41, in order from left to right. The control device 15 displays, among the plurality of selection buttons 41, the operation button 28L related to the device or the like that has been touched (selected) by the user in the operation unit display area 27L.

[0026] The operation screen 21 in FIG. 3 shows a state in which the spindle selection button 41 is selected (see hatching in FIG. 3 ), and the operation button 28L for operating the left spindle unit 12L is displayed in the operation unit display area 27L. For example, when the operation button 28L labeled “Start” in the operation unit display area 27L is touched, the control device 15 rotates the left spindle unit 12L. The control device 15 rotates the left spindle unit 12L based on the rotation speed set in the setting field 43L in the operation unit display area 27L and displays the rotation speed actually measured by an encoder or the like in the display field 45L. When the operation button 28L labeled “Stop” is touched, the control device 15 stops the rotation of the left spindle unit 12L. This allows the user to control the operation of the left spindle unit 12L by operating the operation button 28L, and to cause the left spindle unit 12L to perform machining operations, maintenance operations, checking operations when an error occurs, and the like. The operation button 28L and the setting field 43L are an example of a first operation unit in the present disclosure. Therefore, the "first operation unit that accepts an operation instruction for the first processing device" in the present disclosure is not limited to a decision button that determines the operation content, such as the operation button 28L, but also includes the setting field 43L for inputting settings (parameters, etc.) that determine the operation of the left-side processing device 11L.

[0027] In addition, a plurality of page selection buttons 47 are displayed between the operation unit display area 27L and the right switching button 29R, and the status display unit 25R in the vertical direction. When the number of operation buttons 28L, etc. to be displayed for a device, etc. selected with the selection button 41 is large, the control device 15 displays the operation buttons 28L, etc., divided into multiple pages. The multiple page selection buttons 47 are buttons for selecting these multiple divided pages. In addition, a back button 49, etc. for returning to the display of the previous page is displayed between the operation unit display area 27L and the status display unit 25L in the vertical direction.

[0028] The control device 15 displays, in the operation unit display area 27L, operation buttons 28L, etc., of a device, etc. selected by the user from among the multiple selection buttons 41. For example, when the "jig" selection button 41 is touched, the control device 15 displays, in the operation unit display area 27L, operation buttons 28L for operating a sub-jaw, etc. Furthermore, when the "rotary tool" selection button 41 is touched, for example, the control device 15 displays, in the operation unit display area 27L, operation buttons 28L for operating a rotary tool of the left turret 13L. In this way, the control device 15 executes control of the left-side machining device 11L in response to the user's operation input on the operation screen 21.

[0029] Furthermore, for example, when the control device 15 detects a touch operation of the right switching button 29R in a state in which the operation screen 21 in Fig. 3 is displayed on the touch panel 3A, the control device 15 displays a screen for operating the right-side processing device 11R on the touch panel 3A. Fig. 4 shows an operation screen 22 in which an operation button 28R for accepting operation instructions for the right-side spindle device 12R is displayed in the operation unit display area 27R as an example of a screen for accepting operation instructions for the right-side processing device 11R.

[0030] FIG. 4 is an example of a display screen displayed on the touch panel 3A, and shows an operation screen 22 displaying an operation button 28R for receiving operation instructions for the right spindle unit 12R of the right-side machining device 11R. The operation screen 22 has substantially the same configuration as the operation screen 21 of FIG. 3. Therefore, in describing the operation screen 22, descriptions of portions similar to those of the operation screen 21 will be omitted. As with the operation screen 21 of FIG. 3, the operation screen 22 displays a main body status display unit 23 and status display units 25L and 25R at the top of the screen. In addition, an operation unit display area 27R is displayed below the status display units 25L and 25R. As with the operation unit display area 27L, the operation unit display area 27R displays an operation button 28R for operating the right-side spindle unit 12R, a setting field 43R, and a display field 45R.

[0031] A left switching button 29L is displayed to the left of the operation unit display area 27R. The status display section 25L of the operation screen 22 is surrounded by a red line, and the status display section 25R is surrounded by a blue line. The left switching button 29L, which switches to the operation of the left-side processing device 11L, is surrounded by a red line, and the area frame 26R of the operation unit display area 27R is framed by a blue line (see the dashed line in FIG. 4). The letter "L" 30L is displayed in the upper left corner of the left switching button 29L, and the letter "R" 30R is displayed in the upper left corner of the operation unit display area 27R. The letters 30L and 30R in FIG. 3 and FIG. 4 are displayed in the same manner.

[0032] The colors of the area frame 26L and the right switching button 29R shown in FIG. 3, the left switching button 29L and the area frame 26R shown in FIG. 4, and the status display units 25L and 25R shown in FIGS. 3 and 4 are not limited to the red and blue described above. For example, the outer frame of the status display unit 25L and the area frame 26L may be different colors (e.g., red and yellow). The area frame 26L and the right switching button 29R may be the same color. The outer frames of the status display units 25L and 25R may be the same color. Furthermore, the characters 30L and 30R do not need to be displayed; that is, the left and right identification information does not need to be displayed as characters. Similarly to the character 30R of the right switching button 29R shown in FIG. 3, the character 30R may be displayed in the upper right corner of the area frame 26R in FIG. 4. That is, the display positions of the letter "L" 30L of the area frame 26L and the left switching button 29L may be the same, and the display positions of the letter "R" 30R of the right switching button 29R and the area frame 26R may be the same.

[0033] When the left switching button 29L is touched while the control device 15 is displaying the operation unit display area 27R (operation buttons 28R, etc.), the control device 15 displays a screen (such as the operation screen 21 in FIG. 3 ) for accepting operation instructions for the right-side machining device 11R on the touch panel 3A. As described above, the control device 15 displays the operation buttons 28L, etc., in accordance with the selection of the selection button 41 or the page selection button 47, in the operation unit display area 27L. For example, when the right switching button 29R or the left switching button 29L is operated, the control device 15 displays the screen selected by the selection button 41, etc., on the screen before switching. For example, even if the right switching button 29R is touched with the "spindle" selection button 41 shown in FIG. 3 selected and then the "rotary tool" selection button 41 is selected on the operation screen for the right-side machining device 11R shown in FIG. 4, when the left switching button 29L is touched, the control device 15 displays the operation screen 21 in which the "spindle" selection button 41 before switching was selected. That is, the control device 15 maintains and displays the previous display state.

[0034] Alternatively, the control device 15 may reflect the selection of the selection button 41 or page selection button 47 that was selected at the time of switching on the screen after switching. For example, when the right switching button 29R is operated from a state in which the operation screen 21 in Fig. 3 is displayed to display the operation screen 22 shown in Fig. 4 and the selection button 41 for "rotary tool" is selected, and then the left switching button 29L is operated, the control device 15 may change the selected item from the spindle to the rotary tool and display the operation button 28L for the rotary tool of the left turret 13L. In other words, the display items in the operation unit display areas 27L, 27R may be synchronized before and after switching.

[0035] As described above, in the machine tool 1, the left-side machining device 11L and the right-side machining device 11R have the same configuration, and when the same selection button 41 or page selection button 47 is selected, the same operation buttons 28L, 28R, etc. are displayed in the operation unit display areas 27L, 27R. Therefore, when a user performs an operation on the touch panel 3A, there is a possibility that the user will operate the wrong machining device. If an operation error occurs, there is a risk that the spindle device or other device will be stopped even though it did not need to be stopped, resulting in a decrease in productivity. Furthermore, even if the left-side and right-side machining devices 11L, 11R have similar configurations, even if they are not completely identical, the operation buttons 28L, 28R, etc. will have similar configurations, which may result in an operation error.

[0036] Therefore, the control device 15 displays the letters "L" and "R" 30L and 30R to clearly indicate which of the left and right processing devices 11L and 11R the operation buttons 28L and 28R are intended for. The control device 15 also displays the operation buttons 28L and the right switching button 29R in the order and direction in which the left and right processing devices 11L and 11R are arranged. As shown in FIG. 1 , the touch panel 3A is provided in the center of the front surface of the device cover 2. Therefore, a user standing in front of the touch panel 3A can associate the arrangement of the left and right processing devices 11L and 11R with the arrangement of the operation buttons 28L and the right switching button 29R. The user can intuitively recognize that the operation button 28L displayed to the left of the right switching button 29R is the operation button for the left processing device 11L. As a result, the occurrence of erroneous operation can be reduced.

[0037] Furthermore, the control device 15 displays the operation unit display area 27L in FIG. 3 surrounded by a red area frame 26L (an example of a first color in the present disclosure), and displays the operation unit display area 27R in FIG. 4 surrounded by a blue area frame 26R (an example of a second color in the present disclosure). The control device 15 then displays the right switching button 29R, which switches the operation to the right-side processing device 11R, surrounded by the same blue color as the area frame 26R. This allows the user to recognize the right switching button 29R and the area frame 26R as being associated with each other by the same color before and after operating the right switching button 29R to switch. Therefore, the occurrence of erroneous operations can be reduced by recognizing the colors as well as the arrangement direction and order of the operation button 28L and the right switching button 29R.

[0038] Furthermore, the control device 15 displays the status display units 25L, 25R on the touch panel 3A in the order in which the left- and right-side processing devices 11L, 11R are arranged, i.e., from left to right. The control device 15 displays the status display units 25L, 25R in the same position and with the same items, regardless of whether the control device 15 displays the operation button 28L for operating the left-side processing device 11L or the operation button 28R for operating the right-side processing device 11R. This allows the display of information (such as the NC control mode) that the user should always be notified of, whether maintenance is being performed on either the left-side processing device 11L or the right-side processing device 11R. In other words, regardless of whether the processing device is being operated, the status display units 25L, 25R can display the information the user wants to know.

[0039] Furthermore, the control device 15 displays the area displaying the status display unit 25L (an example of a third area in the present disclosure) surrounded by the same red color as the area frame 26L, and displays the area displaying the status display unit 25R (an example of a fourth area in the present disclosure) surrounded by the same blue color as the right switching button 29R. In this way, the left status display unit 25L, area frame 26L, and left switching button 29L are associated with each other in red, allowing the user to recognize them. Similarly, the right status display unit 25R, area frame 26R, and right switching button 29R are associated with each other in blue, allowing the user to recognize them. For example, when operating the operation button 28L, the color allows the user to recognize that it is necessary to check the status display unit 25L surrounded by the same red color. This reduces the occurrence of misreading the status display units 25L and 25R.

[0040] 3, the right switching button 29R is smaller than the size of the operation unit display area 27L displayed on the same screen (operation screen 21). The same applies to the size relationship between the left switching button 29L and the operation unit display area 27R shown in FIG. 4. An image simulating the shape and arrangement of the multiple operation buttons 28R, etc. shown in FIG. 4 is displayed on the right switching button 29R in FIG. 3. Specifically, an image in which the operation buttons 28R, setting fields 43R, display fields 45R, etc. lined up in the left-right direction are arranged in multiple rows in the up-down direction is displayed on the right switching button 29R. Similarly, an image simulating the multiple operation buttons 28L, etc. shown in FIG. 3 is displayed on the left switching button 29L in FIG. 4.

[0041] The control device 15 then displays the right switching button 29R at the right end of the operation screen 21 in the left-right direction, which is the direction in which the left-side and right-side processing devices 11L, 11R are lined up. The control device 15 also displays the left switching button 29L at the left end of the operation screen 22. This allows the right switching button 29R to be made as small as possible and displayed at the edge of the screen, thereby making it possible to further increase the display area of ​​the operation unit display area 27L. Furthermore, by displaying an image simulating the operation buttons 28R, etc. on the right switching button 29R, even a user operating the button for the first time can intuitively recognize that the right switching button 29R is a button that displays the operation buttons 28R, etc.

[0042] Furthermore, as described above, the left-side and right-side machining devices 11L, 11R have the same configuration, and the configuration of the operation buttons 28L and the like in the operation unit display area 27L is the same as that in the operation unit display area 27R. In such a machine tool 1, the left-side and right-side machining devices 11L, 11R can each perform the same machining on the same type of workpiece, thereby improving productivity. On the other hand, having the left and right devices have the same configuration makes the above-mentioned operation errors more likely to occur. For this reason, in a machine tool 1 in which the left-side and right-side machining devices 11L, 11R have the same configuration, a display method in which the operation buttons 28L and the right switching button 29R are arranged in accordance with the arrangement direction and order of the machining devices is particularly effective.

[0043] Furthermore, the control device 15 changes the content of the display screen in response to operation inputs to the selection button 41, the page selection button 47, or the operation buttons 28L, 28R, etc. The control device 15 determines the operation input procedure, etc. of the touch panel 3A based on the control program PG, for example, and reads out an image corresponding to the determination result from the image data DT and displays it on the touch panel 3A. For example, as shown in FIG. 3, when the size of the operation unit display area 27L displaying the operation buttons 28L, etc. is larger than half the display screen of the touch panel 3A, the control device 15 displays the operation unit display area 27L and the right switching button 29R.

[0044] Therefore, for an image in the image data DT in which the operation unit display area 27L occupies more than half of the display screen, an image of the right switching button 29R is set to the right of the operation unit display area 27L. Note that the control device 15 may determine whether the size of the operation unit display area 27L occupies more than half of the display screen and then determine the screen configuration of the display screen. For example, when the control device 15 reads out multiple images from the image data DT in response to an operation input on the touch panel 3A and combines and displays the read-out images, the control device 15 may determine the size of the operation unit display area 27L and then determine whether or not to display the right switching button 29R.

[0045] On the other hand, depending on the amount of information to be displayed, the size of the operation unit display area 27L may be smaller than half the display screen. Also, when the operation unit display area 27R displays the same operation buttons 28R and the like as those in the operation unit display area 27L, the size of the operation unit display area 27R may also be smaller than half the display screen. When the operation unit display areas 27L and 27R are smaller than half the display screen, it is more efficient to display the two operation unit display areas 27L and 27R on the same screen and receive operation instructions for both the left-side and right-side processing devices 11L and 11R, rather than displaying the right switching button 29R and the like.

[0046] FIG. 5 shows an example of an operation screen displaying both operation buttons 28L and 28R in the operation unit display areas 27L and 27R simultaneously. The operation screen 51 in FIG. 5 is a screen for inputting the correction values ​​(coordinates) of each tool. The horizontal width W of the operation unit display area 27L in FIG. 5 is less than half the width of the operation screen 51. From left to right, the operation unit display area 27L displays the tool number (tool number), the X-axis correction value, the Z-axis correction value, and the tool number (holder number) of the left turret 13L. The user inputs X-axis and Z-axis correction values ​​in the setting field 43L according to tool wear. The control device 15 corrects the X-axis and Z-axis coordinates of the target tool based on the input correction values, thereby correcting the tool position relative to the workpiece. Furthermore, the control device 15 displays the setting field 43L for other tools that could not be displayed in the operation unit display area 27L in response to the operation of the two operation buttons 28L (buttons indicating the up and down directions) in the operation unit display area 27L.

[0047] Furthermore, the operation unit display area 27R is displayed to the right of the operation unit display area 27L, is the same size as the operation unit display area 27L, and displays setting fields 43R and the like for the same items. Furthermore, the operation unit display area 27L is surrounded by a red area frame 26L, and the operation unit display area 27R is surrounded by a blue area frame 26R. For example, the image data DT has an operation screen 51 shown in Fig. 5 stored in advance. That is, the operation screen 51 and the like having a screen configuration corresponding to the size of the operation unit display area 27L and the like are set in advance in the image data DT.

[0048] When the control device 15 receives an operation to display the operation screen 51 via the touch panel 3A, it reads out the operation screen 51 from the image data DT and displays it. As a result, when the size of the operation unit display area 27L is equal to or smaller than half the size of the display screen of the touch panel 3A, the control device 15 can display the operation button 28R and the setting field 43R in addition to the operation button 28L and the setting field 43L. The control device 15 also displays the operation buttons 28L and 28R in the same order and direction as the left and right processing devices 11L and 11R. Furthermore, the control device 15 displays the area frames 26L and 26R shown in FIG. 5 in the same red and blue colors as the area frames 26L and 26R, left switching button 29L, and right switching button 29R shown in FIGS. 3 and 4.

[0049] This makes it possible to receive operation instructions for two processing devices on one screen, for example, when there are only a few display items. Also, by using the same color coding when displaying operation button 28L and right switching button 29R as in Fig. 3 and when displaying two operation unit display areas 27L and 27R as in Fig. 5, the user can distinguish the target processing device by color even when switching between the display as in Fig. 3 and the display as in Fig. 4. This helps prevent erroneous operation.

[0050] Incidentally, the touch panel 3A is an example of a display operation device. The left-side processing device 11L is an example of a first processing device. The right-side processing device 11R is an example of a second processing device. The status display unit 25L is an example of a first status display unit. The status display unit 25R is an example of a second status display unit. The operation button 28L and the setting field 43L are an example of a first operation unit. The operation button 28R and the setting field 43R are an example of a second operation unit. The operation unit display area 27L is an example of a first area. The operation unit display area 27R is an example of a second area.

[0051] Conversely, if the right-side processing device 11R is considered the first processing device and the left-side processing device 11L is considered the second processing device, the order in which the first and second processing devices of the present disclosure are arranged is right, left. In this case, the operation button 28R and the setting field 43R are an example of a first operation unit. The operation button 28L and the setting field 43L are an example of a second operation unit.

[0052] As described above, the present embodiment provides the following effects. In one aspect of this embodiment, the control device 15 displays the operation buttons 28L and the right switching button 29R in the order and direction in which the left and right machining devices 11L, 11R are arranged (see FIG. 3 ). This allows a user viewing the display on the touch panel 3A to intuitively recognize whether the screen displayed is for operating the left machining device 11L or the right machining device 11R, based on the arrangement of the operation buttons 28L and the right switching button 29R. As a result, the occurrence of erroneous operations can be reduced. In particular, in the machine tool 1 of this embodiment, as shown in FIG. 1 , the operation panel 3 (touch panel 3A) is disposed between the left and right machining devices 11L, 11R in the left-right direction. Therefore, a user standing in front of the touch panel 3A can more intuitively recognize that the left operation button 28L relates to the left machining device 11L located to the user's left, and that the right switching button 29R relates to the right machining device 11R located to the user's right.

[0053] It goes without saying that the present disclosure is not limited to the above-described embodiments, and various improvements and modifications are possible within the scope of the present disclosure. For example, in the above embodiment, the operation panel 3 is provided between the left front door 5L (left-side processing device 11L) and the right front door 5R (right-side processing device 11R) in the left-right direction as shown in Fig. 1, but this is not limited to this. For example, as shown in Fig. 6, the left front door 5L (left-side processing device 11L), the right front door 5R (right-side processing device 11R), and the operation panel 3 may be provided in this order from left to right. In this case, too, the occurrence of erroneous operations can be prevented by displaying the information as shown in Fig. 3 or 4 in accordance with the arrangement of the left and right processing devices 11L and 11R. The operation panel 3 may also be provided on the side or top surface of the device cover 2. Furthermore, the direction in which the left and right processing devices 11L, 11R are arranged is not limited to the left-right direction, but may be the front-rear direction or the up-down direction of the machine tool 1. In this case, too, the direction, order, color, etc. of the operation button 28L and the right switching button 29R displayed on the touch panel 3A may be set according to the direction and order in which the left and right processing devices 11L, 11R are arranged. Furthermore, in the above embodiment, the area frames 26L and the like are color coded, but they do not have to be color coded. Furthermore, instead of coloring the frames such as the area frame 26L, the background of the operation unit display area 27L or the status display area 25L may be colored.

[0054] The status display units 25L, 25R do not have to be aligned in the direction of the left and right processing devices 11L, 11R (left-right direction). For example, the status display units 25L, 25R may be aligned in the vertical direction. The size of the right switching button 29R may be made larger than the operation unit display area 27L. Also, an image simulating the operation button 28R does not have to be displayed on the right switching button 29R. Also, text such as "R system switching" may be displayed on the right switching button 29R. The right-side processing device 11R may have a different configuration from the left-side processing device 11L, for example, it may be a machining center. Therefore, when the configurations of the processing devices are different, the operation buttons 28L, 28R, etc. may have different configurations (different items or buttons for the left and right processing devices). The configurations of the operation screens 21, 22, 51 shown in Figures 3 to 5 are merely examples. For example, the status display sections 25L, 25R may be displayed below the operation section display area 27L.

[0055] The control device 15 may be large enough to display the operation unit display areas 27L and 27R on the same screen as shown in FIG. 5, or may display them on separate screens. Furthermore, various configurations can be adopted as the left and right processing devices 11L, 11R, such as a horizontal lathe, a face lathe, a vertical lathe, a milling machine, a drilling machine, and the like.
