       SUMMARY 
     Problem to be Solved 
       [0005]    In this manner, in a processing machine which is provided with an operation panel, an operator displays switching of a plurality of screens, and the operation advances while confirming each display screen. However, when it is necessary to switch the screen which is displayed on the operation panel every time of confirmation, it is necessary to frequently switch the operation panel screen display, work efficiency is bad, and the operator cannot view a plurality of screens at once, which is inconvenient. In this point, as a display technique, there is a multi-display function in which a plurality of screens are displayed so as to overlap, a split display function in which the screen is a split into two screens, and the like. However, the multi-display function cannot be said to be effective since a below overlapped screen cannot be viewed by the operator. In addition, with the split display function in which the screen is split into two, an aspect ratio changes since the screen is reduced without change, and the displayed screen is difficult for the operator to view. 
         [0006]    Therefore, in order to solve the problem, the present disclosure has an object of providing a processing machine and a processing machine line in which, even when performing switching between one screen and two screens, it is easy for the operator to view a screen display. 
       Means for Solving the Problem 
       [0007]    According to an aspect of the present disclosure, there is provided a processing machine including an operation panel with a free vertical and horizontal posture of a display in which a longitudinal dimension and a lateral dimension are different, in which a first display aspect which displays one screen that is displayed on the display and a second display aspect which is disposed lined up with two screens are switched, switch buttons are set in order to perform switching between the first display aspect screen and the second display aspect screen, and the first display aspect screen and the second display aspect screen are mutually switched by operating the switching button, and during the switching, are rotated 90° with respect to the display. 
         [0008]    According to another aspect of the present disclosure, there is provided a processing machine line including a plurality of processing machine bodies which are connected to each other via a line concentrator, and an operation panel with a free vertical and horizontal posture of a display in which a longitudinal dimension and a lateral dimension are different, in which in the operation panel, predetermined information which relates to one processing machine body is displayed on the display by selecting the one processing machine body out of the plurality of processing machine bodies, a display in which a longitudinal dimension and a lateral dimension are different is provided, a first display aspect which displays one screen which is displayed on the display and a second display aspect which is disposed lined up with the two screens are switched, switch buttons are set in order to perform switching between the first display aspect screen and the second display aspect screen, and the first display aspect screen and the second display aspect screen are mutually switched by operating the switching button, and during the switching are rotated 90° with respect to the display. 
       Effects 
       [0009]    According to the present disclosure, for example, a display of an operation panel is switched from one screen display to two screen display, and the screens are rotated 90° with respect to the display by an operator operating a switching button on a first display aspect screen display. For this reason, a horizontally longer screen is displayed along a vertical direction with respect to a display of a vertically longer posture when switched to two screens. Accordingly, since a screen which is displayed to be horizontally longer with respect to the display in a horizontally longer posture in the case of one screen is displayed so as to be horizontally longer without change also in the case of two screens, an aspect ratio of the screen is not largely changed, and it is easy for the operator to view a screen display.

The machine tool driving section  21  has a head stock, a Z-axis drive device, an X-axis drive device, or the like which are major structures of the machine tool  5 , the I/O unit  15  is connected to an auto loader  22  other than such a machine tool driving section  21 , and input and output of a control signal for controlling each driving section are performed. 
         [0028]    The auto loader  22  is provided with a loader driving section for driving a loader that grips and conveys the workpiece, an automatic door diving section for opening and closing an automatic door which is provided on the machine tool  5 , and a jig driving section for operating a jig on which the workpiece is fixed. Then, a LAN interface  17  is connected to the bus line  19 , and is able to wirelessly communicate with the operation panel  8  via the wireless communication device  7  from the hub  6 . In addition, an external interface  18  for connecting to an external personal computer or the like is also provided. 
         [0029]    In the present embodiment, four machine tools  5  are configured so as to be able to be operated using one operation panel  8 . The operation panel  8  is used as an operation panel of the machine tool  5 , and is provided with a display that is display means for performing screen display and input means as well on which an input device is integral and a touch operation is effective, and an antenna for wireless communication. Note that one operation panel  8  may be provided with respect to a plurality of processing machines in the manner of the present embodiment, but one operation panel  8  may be provided with respect to one processing machine. 
         [0030]    The processing machine line  1  of the present embodiment is configured such that it is possible to mount the operation panel  8  with respect to each machine tool  5 . In each machine tool  5 , an attachment tool  501  is formed on a front surface portion, an attachable and detachable section which is not shown in the drawings is formed on a back surface side of the operation panel  8 , and it is possible to attach and detach the operation panel  8  with respect to the machine tool  5 . Accordingly, in the manner of the present embodiment, there is a case of one operation panel  8  with respect to the processing machine line  1 , or a dedicated operation panel  8  may be attached to all four machine, tools  5 . In addition, an attachment structure which is formed of the attachment tool  501  is a mechanism which is able to rotate the attached operation panel  8 . Consequently, the operation panel  8  of a rectangular form is attached by setting a horizontally longer state as a reference posture, but it is also possible to set a vertically longer posture by rotating the operation panel  8  of a rectangular form by 90°. 
         [0031]      FIG. 4  is a block diagram illustrating a control section of the operation panel  8 . The operation panel  8  is configured by a CPU  31  which is a center of the control section, a RAM  32  or a nonvolatile memory  33  which is a memory section, a touch panel  34  which is a display section and an input section, a wireless communication section  35  which performs wireless communication with the machine tool  5 , and the like. The CPU  31  is connected to each section via a bus line  37 , and carries out the overall control of the operation panel  8 . The RAM  32  temporarily stores various data which is generated during execution of various programs using the CPU  31 . The non-volatile memory  33  stores information which is necessary in a process which is performed by the CPU  31 , and a display control program or the like for executing screen display by the operation panel  8  which will be described later is stored. 
         [0032]    In the touch panel  34 , the input device is integral to the display device (display). In detail, a capacitive type or resistive type or the like is used, and it is specified what display element is designated by a detecting the position at which the finger touches using a sensor. The operation panel  8  may be provided with an operation button or the like as an input section other than a touch panel. Then, the wireless communication section  35  performs transmission and reception of a signal with the wireless communication device  7  of the machine tool  5 , for example, wireless LAN or Bluetooth (registered trademark) is used. A millimeter wave or the like may also be used. 
         [0033]    Next,  FIG. 5  is a diagram illustrating a processing machine selection screen which is displayed on the operation panel  8 . The processing machine selection screen  50  is displayed as an initial screen on a display  801  of the operation panel  8 . The selection button for selecting the processing machine which it is possible to communicate with is set on the screen. In the present embodiment, since the four machine tools  5 A,  5 B,  5 C, and  5 D, and the auto loader  22  correspond, five selection buttons  51 ,  52 ,  53 ,  54 , and  55  are disposed on the processing machine selection screen  50 . Then, transmission and reception of the signal is performed wirelessly with the corresponding machine tool  5  and the like by the operator touching one selection button. 
         [0034]    The information from the operation panel  8  accompanying selection has a unique address information which corresponds to the machine tools  5 A,  5 B,  5 C, and  5 D and the auto loader  22 . For this reason, an operation signal is sent from the operation panel  8  with respect to, for example, the selected machine tool  5  and the like, and the predetermined information is sent from the machine tool  5  and the like and displayed on the operation panel  8  by communication via the wireless communication section  35  of the operation panel  8  and the wireless communication device  7  of the processing machine line  1 . 
         [0035]    Here, the selection button  51  is pressed from the processing machine selection screen  50  and the machine tool  5 A is selected. The main menu screen of the machine tool  5 A which is illustrated in  FIG. 6  is displayed on the display  801  of the operation panel  8 . A selection button for selecting predetermined information and the like which relates to the machine tool  5  is disposed on the main menu screen  60 . The predetermined information which relates to the machine tool  5  is the ladder diagram, each individual piece of operation information, I/O monitor information, abnormality information, an instruction manual, or the like. In order to select such predetermined information, each selection button of a ladder diagram button  61 , an I/O monitor button  62 , each individual operation button  63 , an abnormality information button  64 , an instruction manual button  65 , and a processing adjustment button  66  are set on the main menu screen  60 . 
         [0036]    Here, in an NC machine tool such as a machining center, an operation check of the machine tool is performed while the operator views a sequence of a screen that is displayed on a display  801 . The same applies to the machine tool  5  of the present embodiment. As sequence display, the ladder diagram is used which expresses the sequence program using a coil and contact of the relay. In the operation check, the operator displays the predetermined information such as a ladder diagram of the corresponding machine tool  5  with respect to the display  801  of the operation panel  8 , while performing confirmation of the screen. 
         [0037]    During the operation check, other than the ladder diagram, each individual piece of operation information, an I/O monitor, and the like are utilized. For this reason, the operator displays a ladder diagram screen, and an I/O monitor screen on the display  801 . In detail, the operator performs driving of the machine tool  5  by operating an operation switch manually while confirming the ladder diagram screen. Then, the I/O monitor screen is displayed on the display  801 , and the operator confirms in what manner the ON/OFF state of the signal is in each operation from the I/O monitor screen. 
         [0038]    In a case where the operation check and the like is performed on the machine tool  5 , the operator has to confirm a plurality of pieces of information, and it is inconvenient to switch the screen of the operation panel  8  and to display the corresponding information each time. For this reason, in a case were information confirmation is necessary using two screens, the screen of the operation panel  8  is switched by the operator. Here,  FIGS. 7 to 11  are diagrams illustrating screens which are displayed on the display  801  of the operation panel  8 .  FIG. 7  is a diagram illustrating one screen display which is standard, and  FIG. 8  is a diagram illustrating a menu switching state on one screen.  FIG. 9  is a diagram illustrating a case of switching to two screen display, and  FIGS. 10 and 11  are diagrams illustrating a menu switching state on two screens. Here, the screens which are displayed in  FIGS. 7 and 8  are ladder diagram screens, and the screens which are displayed in  FIGS. 9 to 11  are ladder diagram screens and I/O monitor screens. 
         [0039]    In a case where switching of the screen is performed by the operator selecting the machine tool  5 A, first, the main menu screen of the machine tool  5 A which is illustrated in  FIG. 6  is displayed on the display  801  by pressing the selection button  51  from the processing machine selection screen  50  which is illustrated in  FIG. 5 . Then, the screen switches to a ladder diagram screen  71  which is illustrated in  FIG. 7  by the operator pressing the ladder diagram button  61 . At this time, the operation panel  8  is in a state of a horizontally longer reference posture, and the ladder diagram screen  71  such as illustrated in  FIG. 7  is displayed on a horizontally longer display  801 . The display screen which relates to the predetermined information of the machine tool  5 A is not only the ladder diagram screen  71 , but may also be an I/O monitor screen, each individual operation screen, an abnormality information screen, an instruction manual screen, a processing adjustment screen, and the like, and horizontally longer display is a standard for all. 
         [0040]    Next, when a fingertip which touches the left end of the display  801  is slid to the right, as shown in  FIG. 8 , a menu bar  75  appears. Selection buttons  751  to  755  for displaying other screens (screens 1 to 5) than the ladder diagram screen  71  and a two screen switching button  756  are set on the menu bar  75 . When one of the selection buttons  751  to  755  is pressed, display of the display  801  is switched from the ladder diagram screen  71  to a corresponding information screen such as the I/O monitor screen. 
         [0041]    Meanwhile, when the two screen switching button  756  is pressed, as shown in  FIG. 9 , display of the display  801  is switched to two screens. At that time, in a case where the screen is rotated 90° and the display  801  is set to a vertically longer posture, the two screens are disposed one above the other. In  FIG. 9 , display of the display  801  is split into two, the ladder diagram screen  71  and the I/O monitor screen  72  are displayed one above the other. In a case where the two screen switching button  756  is selected, for example, a screen which is displayed during selection and a past screen which is displayed immediately before are displayed. Then, the screen which is displayed during selection is disposed on an upper side, and the past screen is disposed on a lower side. 
         [0042]    In a case where, concerning the respective two screens, the screens are to be modified, in the same manner as the case of one screen, each screen up and down is able to be switched. For example, in a case where the ladder diagram screen  71  on the upper side is to be modified, the fingertip which touches the left end of the display  801  that is a portion on which the ladder diagram screen  71  is displayed, and is in the vertically longer posture, is slid to the right. As shown in  FIG. 10 , by doing this, a menu bar  76  appears on the display  801 . Selection buttons  761  to  765  for displaying other screens than the ladder diagram screen  71  and a one screen switching button  766  are set on the menu bar  76 . Therefore, when one of the selection buttons  761  to  765  are pressed, the screen on the upper side is switched to another information screen from the ladder diagram screen  71 . 
         [0043]    Then, in the same manner as the case in which the I/O monitor screen  72  on the lower side is to be modified, the fingertip which touches the left end of the display  801  that is a portion on which the I/O monitor screen  72  is displayed, and is in the vertically longer posture, is slid to the right. As shown in  FIG. 11 , by doing this, a menu bar  77  appears on the display  801 . Selection buttons  771  to  775  for displaying other screens than the I/O monitor screen  72  and a one screen switching button  776  are set on the menu bar  77 . Therefore, when one of the selection buttons  771  to  775  is pressed, display on the lower side is switched from the I/O monitor screen  72  to another information screen. 
         [0044]    Meanwhile, on one of the menu bars  76  and  77  which appear on the screen up and down, when the one screen switching button  766  or  776  is pressed, as shown in  FIG. 7 , display of the display  801  is switched to one screen. At that time, the screen is rotated 90° and a horizontally longer screen is displayed on the display  801  with a horizontally longer posture. At this time, if the one screen switching button  766  of the menu bar  76  is pressed, the ladder diagram screen  71  is displayed on the display  801 , and if the one screen switching button  776  of the menu bar  77  is pressed, the I/O monitor screen  72  is displayed on the display  801 . 
         [0045]    In addition, in a case where the operator confirms the predetermined information and the like of the other machine tools  5 B,  5 C, and  5 D or the auto loader  22 , the screen returns to the processing machine selection screen  50  which is indicated in  FIG. 5 , and the corresponding button is pressed from selection buttons  52 ,  53 ,  54 , and  55 . Then, in a similar manner to the case of the machine tool  5 A described above, and the operation of the operation panel  8  is performed. Here, in the present embodiment, it is possible to display the predetermined information of a plurality of processing machines in one operation panel  8 . For this reason, it is conceivable that the operator forgets the machine tool  5  of which the predetermined information is displayed. Therefore, it is preferable to set such that it is possible to confirm which target machine tool is displayed on the display  801 . 
         [0046]    For example, each machine tool  5  and the auto loader  22  are divided into each color and the like, and some identification mark is displayed on the screen. In the case of color division, the respective color of each machine tool  5  or the auto loader  22  is determined, and a background and the like is color divided. For example, the machine tool  5 A is set as “red,” the machine tool  5 B is set as “blue,” the machine tool  5 C is set as “yellow,” the machine, tool  59  is set as “green,” and the auto loader  22  is set as “pink.” Consequently, the selection buttons  51  to  55  that are indicated in  FIG. 5  are displayed with the corresponding colors, and on the screen which is indicated in  FIGS. 6 to 11 , the background becomes the corresponding color. Thereby, the operator is able to simply determine the processing machine to which the predetermined information and the like that is displayed relates to. 
         [0047]    Consequently, in the present embodiment as above, the operation panel  8  which displays the predetermined information of the machine tool  5  is switchable between one screen and two screens, and during the switching, the screen is rotated 90°. For this reason, either if there is one screen or if there are two screens, the screen of the predetermined information or the like which relates to the machine tool  5  is displayed so as to be horizontally longer, the posture of the operation panel  8  may be rotated 90° in accordance with the number of screens, and it is easy for the operator to view a screen display. 
         [0048]    In addition, in the present embodiment, rotation of the screen which is performed on the display  801  is displayed only when the number of screens is switched according to the operation of switching buttons  756 ,  766 , and  776 . That is, since there is no automatic rotation due Lo posture change of the operation panel  8 , from a point that a state in which the display is easy to view by the operator is maintained, it is easy to handle. 
         [0049]    In addition, in the present embodiment, since the control device  10  of the machine tool  5  or the conveyance control device of the auto loader  22  is connected to the wireless communication device  7  via the hub  6 , it is possible to communicate with four machine tools  5  and the auto loader  22  using one operation panel  8 . Consequently, since the plurality of processing machines are able to be operated by the operation panel  8  in one location, it is possible to reduce a load on the operator or the number of people. Then, it is also possible to operate the operation panel  8  at an arbitrary location for wireless communication. 
         [0050]    An embodiment of the present disclosure is described above, but the present disclosure is not limited, thereto, and various modifications are possible within a range which does not depart from the gist of the present disclosure. 
         [0051]    In the embodiment, communication between the operation panel  8  and the machine tool  5  is wireless, and the operation panel  8  is described as being attachable and detachable with respect to the machine tool  5 , but if the operation panel  8  is rotatable with respect to the machine tool  5 , the operation panel  8  may not able to be removed and may be connected with respect to the control device  10  using a communication cable. 
         [0052]    In addition, in the embodiment, an example is given of the processing machine line  1  which is formed of the plurality of machine tools  5 , but the processing machine is not necessarily limited to machine tool, or there may be one processing machine which is provided with the operation panel, not a plurality.
