Still another object of the present invention is to show in detail a preferable configuration of the operation panel and the input system switching means in the machine tool.
Still another object of the present invention is to show in more detail a preferable configuration of the operation panel and the input system switching means in the machine tool.

A machine tool provided with an operation panel according to the present invention is a machine tool including a machine tool main body having at least two machining parts and an operation panel shared by each machining part, and the operation panel has a position and a posture. The position / posture state that is in either or both states can be changed freely, and a detection means for detecting the position / posture state is provided, and the operation is performed according to the position / posture state of the operation panel detected by the detection means. Input system switching means for switching an input destination by operating the panel to any one of the respective processing units is provided.
With this configuration, the position / posture state of the operation panel is detected by the detection means. According to the detection result, the input system switching means switches the input destination by operating the operation panel so as to be an appropriate machining part, thereby preventing erroneous input of machining conditions between the machining parts. it can.

In this invention, the machine tool main body has two processing parts arranged side by side, and the operation panel has a left and right central position of the two processing parts, and a left position positioned on the left side with respect to the left and right central position, The input system switching means can input to the right machining portion by operating the operation panel when the operation panel is positioned at the left position. When the operation panel is located at the right position, the input system can be switched to the input system that is input to the left machining unit by operation of the operation panel.
Set the control panel to the left and right center position when machining, set the control panel to the left position when performing input operations such as machining conditions for the right machining section, and move the control panel to the right when performing the above input operations for the left machining section. To position. When the operation panel is located at the left position by the input system switching means, the input system is input to the right machining section by operation of the operation panel. When the operation panel is located at the right position, Since the operation system is switched to the input system that is input to the left machining unit, it is possible to prevent erroneous input of machining conditions between the left and right machining units. Because it is possible to input to the machining part on the opposite side to the side where the operation panel is located, the machining part to be input is easier to see than the other machining part from the viewpoint of the worker who performs the input work. Input without any discomfort.

In the machine tool having the above-described configuration, the operation panel has a common manual operation unit and an automatic operation unit for each processing unit, and the input system switching unit is configured for the manual operation unit. When the operation panel is located at the center position on the left and right, input can be made to both the left and right machining parts.

Below the machine tool body 1 of the machine body cover 50 that extends to the left and right sides are a workpiece loading position and a workpiece unloading position. The workpiece loading table 66 is at the workpiece loading position, and the product is at the workpiece unloading position. Workpiece mounting tables (not shown) are respectively installed.

  6 to 11 show the operation panel 71 and the auxiliary operation panel 72. The operation panel 71 is positioned in front of the processing units 3A and 3B, and the auxiliary operation panel 72 is positioned behind the operation panel 71. As shown in FIG. 1, the installation height of the operation panel 71 and the auxiliary operation panel 72 is set to the eye level of the operator 61 that is easy to operate.

As shown in FIG. 6A, the operation panel 71 is provided with a manual operation unit 73, an automatic operation unit 74, and a display 75 such as a liquid crystal which are common to the left and right processing units 3A and 3B. Yes. Specifically, the manual operation unit 73 is a switch button, and the manual operation unit 74 is a key. The operation units 73 and 74 and the display 75 are arranged on a flat operation surface 76. In the case of this embodiment, the operation surface 76 is formed in an opening / closing door 70b that can be opened and closed with respect to the operation panel main body 70a, and is a surface slightly inclined so as to be closer to the operation panel main body 70a as the upper side. .
The manual operation operating unit 73 is, for example, a start switch and a stop switch. The automatic operation unit 74 is used for various settings for automatic operation. The various settings include setting of machining conditions for automatic operation and setting of the operation of the loader 2 in the left and right machining parts 3A and 3B. The display 75 displays an operation state of the machine tool main body 1 and input guidance for setting by the operation unit 74 for automatic operation. This is an example, and all operations may be performed on the touch panel type display 75.

  As shown in FIG. 6B, the auxiliary operation panel 72 is provided with auxiliary operation units 77A and 77B for the processing units 3A and 3B. The auxiliary operation portions 77A and 77B are of a push button type, for example, for opening / closing the spindle chuck 5a, for opening / closing the shutter 42, and the like. In addition to such an operation unit for manual operation, an operation unit for automatic operation for setting the machining conditions may be provided. Further, the auxiliary operation portions 77A and 77B may be for automatic operation. The auxiliary operation panel 72 has two operation surfaces 78A and 78B which are divided into left and right. The left operation surface 78A is provided with an auxiliary operation portion 77A for the left processing portion 3A, and the right operation surface 78B has a right operation surface. An auxiliary operation portion 77B for the processing portion 3B is provided.

  While the auxiliary operation panel 72 is fixed to the front cover 62, the operation panel 71 has a position / posture state of the first state P1 (shown by a solid line) and the second state as shown in FIG. The state can be changed freely (indicated by a two-dot chain line). The second state includes a leftward second state P2A and a rightward second state P2B. The first state P1 is a state of a front-facing posture in which the surface direction of the operation surface 76 is parallel to the left and right direction when viewed from the front side of the machine, at the left and right center positions of the left and right processing parts 3A and 3B. The second left-facing state P2A is a left-side position that is located on the left side of the left-right center position and that the operation surface 76 faces to the left as compared to the front-facing position. The second right-facing state P2B is a state in which the right-hand side position is located on the right side with respect to the left-right center position, and the right-side posture is such that the operation surface 76 faces the right side compared to the front-side posture.

  In the first state P1, when viewed from the front side of the machine, at least a part of the left and right auxiliary operation portions 77A and 77B of the auxiliary operation panel 72 is hidden by the operation panel 71. In the case of this embodiment, the entire auxiliary operation panel 72 is hidden by the operation panel 71. Therefore, it is difficult to operate the left and right auxiliary operation portions 77A and 77B of the auxiliary operation panel 72 from the front side of the machine. In this machine tool, the auxiliary operation units 77A and 77B are not only physically difficult to operate from the front side of the machine, but even if the auxiliary operation units 77A and 77B are operated by the input system switching means 97 described later. It is not functioning.

  In the left-facing second state P2A, the left auxiliary operation portion 77A of the auxiliary operation panel 72 can be seen from the first state P1 when viewed from the front side of the machine. In the case of this embodiment, the entire auxiliary operation unit 77A can be seen. For this reason, the auxiliary operation portion 77A for the left processing portion 3A can be operated from the front side of the machine. The auxiliary operation portion 77B for the right processing portion 3B remains difficult to operate. Similarly, in the second state P2B facing right, the auxiliary operation unit 77B on the right side of the auxiliary operation panel 72 can be seen from the first state P1 when viewed from the front side of the machine. In the case of this embodiment, the entire auxiliary operation unit 77B can be seen. For this reason, the auxiliary operation portion 77B for the right processing portion 3B can be operated from the front side of the machine. The auxiliary operation portion 77A for the left processing portion 3A remains difficult to operate. In the case of these second states P2A and P2B as well, the auxiliary operation portions 77A and 77B that cannot be seen from the front side of the machine do not function even if operated.

  In the second state P2A (P2B), the operation surface 78A (78B) of the auxiliary operation panel 72 is positioned substantially on the operation surface 76 of the operation panel 71, and the operation surfaces 76 and 78A (78B) are substantially parallel. It is. The left / right visible width b of the operation panel 71 in the second state P2A (P2B) is narrower than the left / right visible width a of the operation panel 71 in the first state P1. Here, the left and right visible widths are the maximum width in the left-right direction of the operation panel 71 projected in the front-rear direction, and change according to the change in the attitude of the operation panel 71.

A switching mechanism for switching the operation panel 71 between the first state P1 and the second states P2A and P2B will be described. 8, 9, and 10 are a plan view, a partially broken front view, and a partially broken side view, respectively, in which a part of the switching mechanism is omitted.
The switching mechanism 80 has a box-shaped support arm 82 interposed between the operation panel 71 and the fixed base 81 below the operation panel 71. The operation panel 71 is supported on the support arm 82 by a ring-shaped swivel bearing 83 so as to be turnable about a turning center axis O1 facing in the vertical direction. The support arm 82 is provided on the fixed base 81 so as to be rotatable around a rotation center axis O2 that is parallel to the rotation center axis O1 and has a different plane position by a rotating seat bearing 84. The fixed base 81 is attached to the front cover 62 by a pair of left and right legs 81a. The machine tool body 1 and the operation panel 71 are electrically connected by a cable (not shown) that passes through the support arm 82 and the upper and lower swivel seat bearings 83 and 84.

  A link 85 integral with the operation panel 71 is provided in the support arm 82, and the link 85 is rotatably supported by a link support shaft 86 fixed to the support arm 82. The link support shaft 86 is located coaxially with the turning center axis O1. The link 85 is extended to the operation surface 76 side of the operation panel 71 in a plan view, and a cam support shaft 87 is provided at the tip thereof. The cam support shaft 87 passes through an arc-shaped hole 88 formed in the bottom plate 82 a of the support arm 82 and extends below the support arm 82. The arc-shaped hole 88 is an arc-shaped hole centered on the link support shaft 86, and the cam support shaft 87 is movable within the arc-shaped hole 88 when the link 85 rotates around the link support shaft 86. Yes. A sub cam 89 and a main cam follower 90 made of a roller are attached to the lower portion of the cam support shaft 87 positioned below the support arm 82. The angle of the link 85 and the sub cam 89 is freely changeable, and the main cam follower 90 is rotatable with respect to the cam support shaft 87.

As shown in FIG. 8, the secondary cam 89 has a plane shape that is line symmetric along a center line L that passes through the cam support shaft 87. The sub cam 89 has a long hole 89a on the center line L, and a pin 91 provided on the support arm 82 is engaged with the long hole 89a. As a result, the sub cam 89 is swingable about the pin 91 in a swinging manner, and is movable in the direction of the center line L within the effective length of the long hole 89a. At least when the operation panel 71 is in the first state, the secondary cam follower 92 made of a roller is in contact with the cam surface 89b of the secondary cam 89. The sub cam follower 92 is rotatably supported on the fixed base 81.
On the fixed base 81, a main cam 93 having a cam groove 93a with which the main cam follower 90 is engaged is fixed. As shown in FIG. 8, the cam groove 93a of the main cam 93 has a curved shape surrounding the rotation center axis O2 except for the front portion.

  The main cam 93 and the main cam follower 90 constitute a main cam mechanism C1, and the sub cam 89 and the sub cam follower 92 constitute a sub cam mechanism C2. The main cam mechanism C1 and the sub cam mechanism C2 constitute a composite cam mechanism C. The main cam mechanism C1 gives a predetermined limit to the turning of the operation panel 71 with respect to the support arm 82, whereby the operation panel 71 is switched when the operation panel 71 is switched between the first state P1 and the second states P2A and P2B. Acts to regulate the posture. In the case of this embodiment, the attitude of the operation panel 71 is the direction of the operation panel 71 around the turning center axis O1. The sub cam mechanism C2 assists in smoothing and ensuring the operation of the main cam mechanism C1.

FIG. 11 is a diagram illustrating the operation of the operation panel 71. When a force is applied to the operation panel 71 in the right direction from the first state P1 in (A), the operation panel 71 goes through the steps (B) to (E) in order, and then the second leftward operation in (F). To state P2A. At that time, the center position of the operation panel 71 in the plan view moves in the left-right direction while the center position in the plan view moves forward. Precisely, it moves by drawing an arcuate movement locus K centering on the rotation center axis O2. In this embodiment, the plan view center position of the operation panel 71 coincides with the position of the turning center axis O1. During movement, the operation panel 71 changes its posture from the posture in which the surface direction of the operation surface 76 is parallel to the left and right directions when viewed from the front side of the machine to the posture in which the operation surface 76 faces the left side by the action of the main cam mechanism C1. Let
The sub cam mechanism C2 operates as follows. In the first state (A), the support arm 82 is in a neutral state in which the support arm 82 can be rotated clockwise and counterclockwise about the rotation center axis O2, and an external force is applied to the operation panel 71. The operation of the support arm 82 is unstable. Therefore, the auxiliary cam mechanism C2 applies a force in a predetermined direction around the rotation center axis O2 to the support arm 82 to smooth and ensure the operation of the support arm 82. When the operation panel 71 switches from the first state P1 to the second leftward state P2A (FIG. 11), a clockwise force is applied to the support arm 82 about the rotation center axis O2. In addition, as the sub cam 92 moves along the cam surface 89 b of the sub cam 89, the pin 91 moves in the long hole 89 a of the sub cam 89.
As described above, when the operation panel 71 moves while changing its posture, the rearmost part of the operation panel 71 is always at the same position in the front-rear direction. For this reason, when in the first state P1, the operation panel 71 and the auxiliary operation panel 72 can be disposed close to each other in the front-rear direction, and the operation panel 71 can be provided in a compact manner. That is, when the operation panel 71 is simply turned, if the distance between the operation panel 71 and the auxiliary operation panel 72 is narrow, the corner on the rear side of the operation panel 71 may interfere with the auxiliary operation panel 72 during the turn. Such interference can be prevented by moving left and right while moving to the right. The same applies to the case of switching from the first state P1 to the second state P2B facing right. Since the structure of the switching mechanism 80 is relatively simple, the operation is reliable and the adjustment of the operation is easy.

  Sensor mounting members 94 are fixed to the left and right legs 81a of the fixed base 81, and sensors 95A and 95B as detection means for detecting the position / posture state of the operation panel 71 are mounted on the sensor mounting members 94, respectively. Yes. The sensors 95A and 95B are proximity switches, for example, and the detection bodies 96 of the sensors 95A and 95B are attached downward to the bottom surface of the swivel seat bearing 84. The detected body 96 has two detected portions 96aA and 96aB. When the operation panel 71 enters the second state P2A facing left, the sensor 95A detects the detected portion 96aA and the sensor 95A is turned on. When 71 enters the second state P2B facing right, the sensor 95B detects the detected portion 96aB and the sensor 95B is turned on. The sensors 95A and 95B may be photoelectric switches.

As shown in FIG. 6, the outputs of the sensors 95 </ b> A and 95 </ b> B that are detection means are transmitted to the input system switching means 97. The input system switching means 97 receives operation signals from the operation units 73, 74, 77A, and 77B, and outputs to the processing units 3A and 3B whether the operation signals are input to the processing units 3A and 3B. Switch accordingly. Due to the action of the input system switching means 97, the input system from the operation units 73, 74, 77A, 77B to the processing units 3A, 3B is as follows. The input system to the processing units 3A and 3B is specifically an input system to the processing unit control devices 3Ab and 3Bb.
When the operation panel 71 is in the first state P1, the operation signal of the manual driving operation unit 73 is input to both the left and right processing units 3A and 3B, and the operation panel 71 is in the second state P2A facing left. In some cases, it is input only to the left processing unit 3A, and when the operation panel 71 is in the second state P2B facing right, it is input only to the right processing unit 3B.
When the operation panel 71 is in the first state P1, the operation signal for the automatic operation unit 74 is not input to any of the left and right processing units 3A and 3B, and the operation panel 71 is in the second state P2A facing left. In some cases, it is input only to the left processing unit 3A, and when the operation panel 71 is in the second state P2B facing right, it is input only to the right processing unit 3B.
Regarding the auxiliary operation units 77A and 77B, when the operation panel 71 is in the first state P1, the operation signals of the left and right auxiliary operation units 77A and 77B are not input to the processing units 3A and 3B, and the operation panel 71 When the second state P2A is leftward, only the operation signal of the left auxiliary operation unit 77A is input to the left processing unit 3A, and when the operation panel 71 is in the second state P2B rightward, the right auxiliary operation is performed. Only the operation signal of the unit 77B is input to the right processing unit 3B.

  A display switching means 98 is connected to the input system switching means 97 or the sensors 95A and 95B. The display switching means 98 switches the display content of the display 75 according to the input system switched by the input system switching means 97 or according to the position / posture state of the operation panel 71 detected by the sensors 95A and 95B. It is. For example, when the input system is input to the left processing unit 3A, information about the left processing unit 3A is displayed, and when the input system is input to the right processing unit 3B, the right processing unit is displayed. Information about the part 3B is displayed. As in the example of FIG. 6, the input is not input to the display switching means 98 via the input system switching means 97, but is directly input to the display switching means 98 from the operation units 73, 74, 77A, 77B. Also good.

  The machine tool provided with this operation panel is operated with the fence portions 51A and 51B closed and in the state Q1. During operation, the loader 2 supplies and discharges workpieces (not shown) to the processing units 3A and 3B of the machine tool main body 1. Specifically, when the traveling body 31 moves left and right, the front and rear moving base 32 moves back and forth, and the telescopic support body 33 expands and contracts, the loader head 34 moves between the work carry-in position and the processing parts 3A and 3B. The loader chuck 35 in the downward position at the position grips the workpiece on the material workpiece mounting table 66, and the loader chuck 35 in the horizontal position supplies the workpiece to the spindle 5 at the processing portions 3 </ b> A and 3 </ b> B. Further, the loader head 34 moves between the processing units 3A and 3B and the workpiece unloading position, and the loader chuck 35 in the horizontal position at the processing units 3A and 3B receives the processed product workpiece from the main shaft 5 and moves to the workpiece unloading position. The loader chuck 35 in the downward position places the product workpiece on the product workpiece mounting table. When the loader head 34 descends into the processing areas S1A and S1B, the shutters 42 of the partition plates 40A and 40B are opened in a fully opened state in conjunction with the elevation of the loader head 34.

  In the processing parts 3A and 3B, turning is performed on the workpiece supported by the main shaft 5. Specifically, the workpiece is moved in the feed direction of the tool 10 by the back-and-forth movement of the headstock 6, and the tool 10 is moved in the cutting direction by the left / right slide of the tool rest 7. When machining on both sides of the workpiece in the axial direction, the workpiece reversing machine 38 reverses the direction of the workpiece. During the turning process, the shutters 42 of the partition plates 40A and 40B are closed, so that the chips do not scatter outside the processing areas S1A and S1B. Chips generated in the turning process fall on the chip conveyor 22 through the chip discharge space 8 and are carried by the chip conveyor 22 and discharged to the outside.

  In accordance with changes in the type of workpiece to be machined, machining content, etc., machining condition setting change work and machining part setup work are performed. The processing condition setting is changed by the automatic operation unit 74 of the operation panel 71. In the case of the setup work for exchanging the tool 10, as shown in FIG. 12, the fence 51A (51B) on the side of the processing section S1A (S1B) is stopped in a state where the processing of the corresponding processing section S1A (S1B) is stopped. Is set to the first open state Q2, and the shutter 42 of the partition plate 40A (40B) is set to the half open state, and the processing region S1A is formed from the opening 60 formed between the processing region S1A (S1B) and the worker space S2. (S1B) Put your hand in. In the case of a setup operation for exchanging the spindle chuck 5a, as shown in FIG. 13, after the operation of the entire machine tool is stopped, the fence portion 51A (51B) on the side of the corresponding machining portion S1A (S1B) is set to the second. And the partition plate 40A (40B) is opened, and the operation is performed over the loader travel area S1L.

  At the time of processing, the operation panel 71 is in the first state P1 in which the surface direction of the operation surface 76 is parallel to the left and right directions when viewed from the front side of the machine. In this state, the auxiliary operation panel 72 cannot be seen behind the operation panel 71 from the front side of the machine, and it is difficult to operate the left and right auxiliary operation units 77A and 77B of the auxiliary operation panel 72. For this reason, it can prevent operating the process part 3A, 3B accidentally during a process. When the operation panel 71 is in the first state P1, a part of the operation panel 71 overlaps the fence parts 51A and 51B in the front and rear, but since the amount of overlap is small, the window 53 of the fence parts 51A and 51B is passed through. This is not an obstacle to visually confirming the processed parts 3A and 3B.

  When an input operation is performed when changing the setting of the processing conditions, the position / posture state of the operation panel 71 is switched so that the operation surface 76 of the operation panel 71 faces the input processing portion. That is, when inputting to the processing unit 3A, the second state facing left is P2A, and when inputting to the processing unit 3B, the second state facing right is P2B. In the second state P2A (P2B), the input system switching means 97 can input only to the processing part 3A (3B) on the side to be input, so that it is possible to prevent the left and right from being input incorrectly. It is. Further, since the input processing unit 3A (3B) is easier to see than the other processing unit 3B (3A), the input operation can be performed psychologically without any sense of incongruity.

  Similarly to the above, when the setup operation is performed on the processing units 3A and 3B, the position / posture of the operation panel 71 is set so that the operation surface 76 of the operation panel 71 faces the processing unit performing the setup operation. Switch the state. That is, when the setup operation is performed on the processing unit 3A, the second state is set to P2A, and when the setup operation is performed on the processing unit 3B, the second state P2B is set to the right. By setting the second state P2A (P2B), the auxiliary operation portion 77A (77B) on the side where the setup work is performed can be seen from the front side of the machine. The auxiliary operation unit 77A (77B) is operated to open / close the spindle chuck 5a, open / close the shutter 42, and the like. The auxiliary operation portion 77B (77A) on the opposite side is difficult to operate from the front side of the machine, and does not function even if there is an erroneous operation, so there is no risk of manually operating the opposite processing portion by mistake. In the second state P2A (P2B), the operation panel 71 is moved to the left and right from the front position of the fence portion 51A (51B), and the visible width of the left and right of the operation panel 71 is narrower than that in the first state P1. Therefore, the space in front of the fence part 51A (51B) is widened, and the opening / closing operation of the fence part 51A (51B) and the work on the processing parts 3A and 3B performed by putting the body into the processing part space S1 are easy to perform.

In the above embodiment, both the position and the posture are changed when the operation panel 71 is switched from the first state P1 to the second state P2A (P2B), but only the position or the posture of the operation panel 71 is changed. The structure to change may be sufficient.
FIG. 14 shows an example in which only the position of the operation panel 71 is changed. This machine tool includes an operation panel 71 and an auxiliary operation panel 72 arranged on the rear side. The auxiliary operation panel 72 is located between the left and right fence parts 51A and 51B in front view. The operation panel 71 is movable in the left-right direction, and a left-right center position P ₁ 1 located at the left-right center of the two processing parts 3A, 3B, and a right-side position P ₁ located on the right side with respect to the left-right center position P ₁ 1. 2A and the left side position P ₁ 2B located on the left side with respect to the left and right center position P ₁₁ . When viewed from the front side of the machine, in a state where the operation panel 71 is in the left and right center position P ₁₁ , both the left and right auxiliary operation portions 77A and 77B of the auxiliary operation panel 72 are hidden by the operation panel 71 and the operation panel 71 is in the right position P in the state in ₁ 2A, only the right side of the operating section 3B of the auxiliary operation panel 72 is concealed in the operation panel 71, in a state where the operation panel 71 is to the left position P ₁ 2B, only the left side of the operation portion 77A of the auxiliary operation panel 72 Is hidden on the operation panel 71.

The input system is changed to the following input system by an input system switching means (not shown). The operation unit 73 for manual operation of the operation panel 71 can be input to both the left and right machining units 3A and 3B when the operation panel 71 is positioned at the left and right center position P ₁₁ , and the operation panel 71 is positioned at the right position P _1. when located 2A, a possible only entered for the left processing unit 3A, when the operation panel 71 is positioned on the left side position P ₁ 2B, it is only possible input to the right of the machining unit 3B. When the operation panel 71 is positioned at the left and right center position P ₁₁ , the operation unit 74 for automatic operation of the operation panel 71 cannot be input to both the left and right machining sections 3A and 3B, and the operation panel 71 is positioned at the right position P _1. when located 2A, a possible only entered for the left processing unit 3A, when the operation panel 71 is positioned on the left side position P ₁ 2B, it is only possible input to the right of the machining unit 3B. As for the auxiliary operation sections 77A and 77B of the auxiliary operation panel 72, only the operation section visible from the machine front side can be input. That is, when the operation panel 71 is to the right position P ₁ 2A, the left auxiliary operation unit 77A becomes possible input, when the operation panel 71 is positioned on the left side position P ₁ 2B, the right auxiliary operating unit 77B Input becomes possible.
Also according to the configuration of this machine tool, the same effect as that of the above embodiment can be obtained.

FIG. 15 shows an example in which only the attitude of the operation panel 71 is changed. This machine tool includes an operation panel 71 and a pair of left and right auxiliary operation panels 72A and 77B arranged on the rear side thereof. The auxiliary operation panels 72A and 77B are located between the left and right fence portions 51A and 51B in a front view. Operation panel 71 is pivotable in the pivot axis O1 around the vertical direction, parallel to the front facing posture P _{2 1} to the direction of lateral surface direction of the operation surface 76 is viewed from the machine front, the operating surface 76 There switched to the left position _P 2 2A facing to the left compared to the frontal orientation _{P 2} 1, and the right attitude _P 2 2B the operation surface 76 is directed to the right compared to the frontal orientation _{P 2} 1.
