BEST MODE FOR CARRYING OUT THE INVENTION

[0010] Hereinafter, with reference to the drawings, the setup station 10 and the machine tool 1 in the embodiment will be described.

In FIGS. 16 and 17, only the outline of the pallet PT is shown by a broken line. FIG. 18 is a schematic perspective view schematically showing a state where the attachment portion 20 to which the auxiliary tool 3 is attached is arranged on the pallet PT. FIG. 19 is a schematic side view schematically showing a state where the pallet PT is removed from the first table 23. FIGS. 20 and 21 are schematic perspective views schematically showing the setup station 10A in the first embodiment.

[0012] As illustrated in FIGS. 1 and 2, the setup station 10A includes a support 2 and an auxiliary tool 3. Additionally, the setup station 10A may include an opening OP.

[0013] As illustrated in FIGS. 1 and 2, the support 2 is disposed in a setup area RG1 where the workpiece W is set up. The support 2 supports the workpiece W.

[0014] The opening OP allows access to the setup area RG1. More specifically, the opening OP allows an operator to access the setup area RG1 from outside the setup area RG1 through the opening OP.

[0015] In the example described in FIGS. 1 and 2, the workpiece W can be carried into the setup area RG1 from outside the setup area RG1 through the opening OP.

[0016] In the example described in FIGS. 1 and 2, the opening OP is provided in the wall 18 that defines the setup area RG1.

[0017] The auxiliary tool 3 assists in manually turning the support 2. More specifically, the operator can turn the support 2 around the first axis AX1 by operating the auxiliary tool 3. In the example described in FIG. 2, the first axis AX1 is substantially parallel to the vertical direction.

[0018] As illustrated in FIG. 2, when manual turning of the support 2 is required, the auxiliary tool 3 is attached to the support 2. As illustrated in FIGS. 2 and 3, after the auxiliary tool 3 is attached to the support 2, the operator can turn the support 2 using the auxiliary tool 3. More specifically, after the auxiliary tool 3 is attached to the support 2, the operator can turn the support 2 around the first axis AX1 using the auxiliary tool 3.

[0019] As illustrated in FIG. 4, when manual turning of the support 2 is not required, the auxiliary tool 3 is separated from the support 2 (see the dashed arrow AR1).

[0020] In the examples shown in FIGS. 1 to 4, the auxiliary tool 3 is a detachable auxiliary tool that is attached to the support 2 during use and separated from the support 2 when not in use.

[0021] In the first embodiment, the operator can easily turn the support 2 that supports the workpiece W by using the auxiliary tool 3. Therefore, the work load on the operator is reduced as compared with the case of turning the support 2 without using the auxiliary tool 3. More specifically, the operator can turn the support 2 with a relatively small force.

[0022] In the first embodiment, the auxiliary tool 3 is separated from the support 2 when not in use. In this case, chips or coolant liquid do not adhere to the auxiliary tool 3 when it is not in use. Therefore, the labor or frequency of cleaning the auxiliary tool 3 is reduced.

[0023] (Optional additional configuration) Subsequently, with reference to FIGS. 1 to 21, an optional additional configuration that can be adopted in the setup station 10A in the first embodiment will be described.

[0024] (Auxiliary tool 3) In the example shown in FIG. 5, the auxiliary tool 3 can be attached to the support 2 in a state where the auxiliary tool 3 crosses the opening OP.

[0025] In the example shown in FIG. 5, when the auxiliary tool 3 is attached to the support 2, a part 32 of the auxiliary tool 3 (more specifically, a gripping part 321 gripped by the operator) protrudes outside the opening OP through the opening OP.

[0026] As illustrated in FIGS. 6 and 7, when a part 32 of the auxiliary tool 3 protrudes outside the opening OP, the operator can easily operate the part 32 of the auxiliary tool 3. For example, since the operator can operate the part 32 of the auxiliary tool 3 at a position close to his / her torso, the operating force can be suitably transmitted to the auxiliary tool 3.

[0027] When a part 32 of the assistive device 3 protrudes outside the opening OP, the distance between the part 32 of the assistive device 3 and the pivot axis of the support 2 (in other words, the first axis AX1) increases. Therefore, an operator who operates a part 32 of the assistive device 3 (more specifically, the gripping part 321) can apply a relatively large torque to the support 2 with a relatively small force. That is, the lever principle is preferably utilized.

[0028] Also, when a part 32 of the assistive device 3 protrudes outside the opening OP, the hand or arm of the operator who operates the assistive device 3 is less likely to be pinched between the edge of the opening OP and the assistive device 3.

[0029] In the example shown in FIG. 8, the assistive device 3 has a mounting end 34 attached to the support 2 and a gripping part 321 gripped by an operator.

[0030] As illustrated in FIG. 8, a state where the mounting end 34 is attached to the support 2 is defined as an attachment state. In the examples shown in FIGS. 8 and 9, the height position of the gripping part 321 in the attachment state can be adjusted.

[0031] As illustrated in FIG. 10, the height position of the gripping part 321 may be adjustable in the attachment state where the attachment end 34 is attached to the support 2. In the example shown in FIG. 10, the attachment end 34 extends along the second axis AX2. In the example shown in FIG. 10, in the attachment state where the attachment end 34 is attached to the support 2, when the assistive device 3 is rotated about the second axis AX2, the height position of the gripping part 321 is changed (see the dashed arrow AR2). Alternatively, the height position of the gripping part 321 may be adjustable only at the timing when the attachment end 34 is attached to the support 2.

[0032] When the height position of the gripping part 321 is adjustable, the gripping part 321 can be arranged at a height at which it is easy for the operator to apply an operating force. For example, when the operator's height is relatively high, the height of the gripping part 321 is adjusted to a relatively high position. On the other hand, when the operator's height is relatively low, the height of the gripping part 321 is adjusted to a relatively low position.

[0033] As illustrated in FIG. 11, the support 2 may have a hole 21h for receiving the mounting end portion 34. In the example shown in FIG. 11, the support 2 has a circular hole 21h for receiving the mounting end portion 34. In the example shown in FIG. 11, the mounting end portion 34 has a protrusion 34p received in the hole 21h of the support 2. As illustrated in FIG. 12, the mounting end portion 34 may have a columnar protrusion 34p (e.g., a cylindrical protrusion 34p) received in the hole 21h of the support 2.

[0034] In the example shown in FIG. 11, the hole 21h of the support 2 receives the mounting end portion 34 (more specifically, the protrusion 34p) such that the mounting end portion 34 is rotatable about the second axis AX2. In this case, with the mounting end portion 34 received in the hole 21h, the auxiliary tool 3 can be rotated about the second axis AX2 (see FIG. 10). Alternatively, as illustrated in FIG. 13, the support 2 may have a columnar protrusion 21p (e.g., a cylindrical protrusion 21p), and the mounting end portion 34 may have a hole 34h (e.g., a circular hole 34h) for receiving the columnar protrusion 21p (e.g., a cylindrical protrusion 21p).

[0035] In the example shown in FIG. 11, the central axis of the hole 21h may be substantially parallel to the horizontal plane. In the example shown in FIG. 13, the central axis of the protrusion 21p may be substantially parallel to the horizontal plane.

[0036] In the examples shown in FIGS. 10, 11, and 13, the engagement between the mounting end portion 34 and the support 2 is an engagement that allows rotation of the mounting end portion 34 about the second axis AX2. Alternatively, the engagement between the mounting end portion 34 and the support 2 may be an engagement that does not allow rotation of the mounting end portion 34 about the second axis AX2.

[0037] In the example shown in FIG. 14, the auxiliary tool 3 has a first portion 33 including a mounting end portion 34 extending along the second axis AX2, and a second portion 31 extending from the first portion 33 in a direction different from the direction along the second axis AX2. In the example shown in FIG. 14, the second portion 31 is connected to the first portion 33 via a bent portion 35. In the example shown in FIG. 14, the second portion 31 includes a gripping portion 321.

[0038] The angle α formed between the first portion 33 and the second portion 31 is, for example, greater than 90 degrees and less than 180 degrees. The angle α formed between the first portion 33 and the second portion 31 may be 120 degrees or more and 150 degrees or less.

[0039] In the examples shown in FIGS. 11 and 13, the mounting end portion 34 can be attached to the support 2 in one action. More specifically, the mounting end portion 34 can be attached to the support 2 by simply inserting a protruding portion 34p or 21p provided on one of the mounting end portion 34 and the support 2 into a hole portion 21h or 34h provided on the other of the mounting end portion 34 and the support 2. When the mounting end portion 34 can be attached to the support 2 in one action, the auxiliary tool 3 can be quickly attached to the support 2.

[0040] The attachment end portion 34 and the support 2 may be connected to each other by a loose fit. More specifically, in a state where a protrusion provided on one of the attachment end portion 34 and the support 2 is inserted into a hole provided on the other of the attachment end portion 34 and the support 2, a slight gap may be formed between the protrusion and the hole. In this case, it is easy to insert the protrusion into the hole. In the examples described in FIGS. 11 and 13, the attachment end portion 34 and the support 2 are connected to each other by fitting, not screwing. In this case, the attachment end portion 34 can be quickly attached to the support 2. In the examples described in FIGS. 11 and 13, the attachment end portion 34 is directly attached to the support 2. In this case, the auxiliary tool 3 can be quickly attached to the support 2 as compared with the case where the attachment end portion 34 is attached to the support 2 via a fixing member. Note that in the embodiment, the connection between the attachment end portion 34 and the support 2 is not limited to the connection by fitting. Also, the attachment of the attachment end portion 34 to the support 2 is not limited to direct attachment.

[0041] The attachment end portion 34 may be removable from the support 2 in one action. In the examples described in FIGS. 11 and 13, the attachment end portion 34 can be removed from the support 2 simply by pulling out a protrusion 34p or a protrusion 21p provided on one of the attachment end portion 34 and the support 2 from a hole 21h or a hole 34h provided on the other of the attachment end portion 34 and the support 2. When the attachment end portion 34 can be removed from the support 2 in one action, the auxiliary tool 3 can be quickly removed from the support 2.

[0042] In the example described in FIG. 8, the gripping portion 321 is the free end portion 321a of the auxiliary tool 3. In the example described in FIG. 8, when the auxiliary tool 3 is attached to the support 2, the auxiliary tool 3 is cantilever-supported by the support 2.

[0043] In the example described in FIG. 8, in a state where the auxiliary tool 3 is attached to the support 2, the distance between the pivot axis of the support 2 (in other words, the first axis AX1) and the free end portion 321a is larger than the distance between the pivot axis of the support 2 (in other words, the first axis AX1) and the attachment end portion 34.

[0044] In the example shown in FIG. 5, in a state where the auxiliary tool 3 is attached to the support 2, the maximum value M1 of the distance between the pivot axis of the support 2 (in other words, the first axis AX1) and the free end 321a is greater than the minimum value M2 of the distance between the pivot axis of the support 2 (in other words, the first axis AX1) and the opening OP. The above-mentioned maximum value M1 may be 1.2 times or more, 1.5 times or more, or 1.8 times or more of the above-mentioned minimum value M2. Thereby, since the gripping portion 321 which is a part of the auxiliary tool 3 is always located outside the opening OP, the operator can operate the auxiliary tool 3 without putting a hand into the setup area RG1.

[0045] In the example shown in FIG. 14, the auxiliary tool 3 is a rod-shaped auxiliary tool. In the example shown in FIG. 14, the auxiliary tool 3 has a first portion 33 including a mounting end 34, a second portion 31 including a gripping portion 321, and a bending portion 35 connecting the first portion 33 and the second portion 31. The first portion 33 may have a linear shape or other shape. The second portion 31 may have a linear shape or other shape.

[0046] The first portion 33 of the auxiliary tool 3 may have a protrusion 34p received in the hole 21h of the support 2 and a flange 34f in contact with the side surface of the support 2. The flange 34f defines the insertion amount of the protrusion 34p with respect to the hole 21h.

[0047] The shape of the auxiliary tool 3 is not limited to the shape shown in FIG. 14. For example, as illustrated in FIG. 15, the auxiliary tool 3 may be a linear auxiliary tool without a bending portion.

[0048] In this specification, one rotation direction around the first axis AX1 is defined as the first rotation direction R1, and the rotation direction opposite to the first rotation direction R1 is defined as the second rotation direction R2.

[0049] In the example described in FIG. 16, the attachment end portion 34 can be attached to the support 2 such that the gripping portion 321 is positioned on the first rotation direction R1 side around the first axis AX1 rather than the bending portion 35. In this case, by operating the gripping portion 321, it is easy to rotate the support 2 in the first rotation direction R1. In the example described in FIG. 17, the attachment end portion 34 can be attached to the support 2 such that the gripping portion 321 is positioned on the second rotation direction R2 side around the first axis AX1 rather than the bending portion 35. In this case, by operating the gripping portion 321, it is easy to rotate the support 2 in the second rotation direction R2.

[0050] (support 2) In the examples described in FIGS. 2 and 3, the support 2 is rotatable around the first axis AX1.

[0051] In the examples described in FIGS. 2 and 3, the support 2 includes a pallet PT to which the work W is attached and a first table 23 that supports the pallet PT. The first table 23 is rotatable around the first axis AX1. In the examples described in FIGS. 2 and 3, each of the first table 23 and the pallet PT constitutes a part of the support 2.

[0052] In the examples described in FIGS. 11 and 13, the auxiliary tool 3 can be attached to the first table 23 (more specifically, the side surface 230 of the first table 23). Alternatively, as illustrated in FIG. 18, the auxiliary tool 3 may be attachable to the pallet PT (more specifically, the side surface Ps of the pallet PT).

[0053] In the examples described in FIGS. 11, 13, and 18, the support 2 has an attachment portion 20 to which the auxiliary tool 3 can be attached (for example, a hole portion 21h to which the auxiliary tool 3 can be attached, or a protruding portion 21p to which the auxiliary tool 3 can be attached).

[0054] As illustrated in FIGS. 16 and 17, the support 2 may have a plurality of attachment portions 20 including a first attachment portion 20a to which the auxiliary tool 3 can be attached and a second attachment portion 20b to which the auxiliary tool 3 can be attached. In the example shown in FIG. 16, the first table 23 has a plurality of attachment portions 20 including a first attachment portion 20a to which the auxiliary tool 3 can be attached and a second attachment portion 20b to which the auxiliary tool 3 can be attached. In the example shown in FIG. 18, the pallet PT has a plurality of attachment portions 20 including a first attachment portion 20a to which the auxiliary tool 3 can be attached and a second attachment portion 20b to which the auxiliary tool 3 can be attached.

[0055] In the examples shown in FIGS. 16 and 17, the auxiliary tool 3 (more specifically, the attachment end portion 34 of the auxiliary tool 3) can be selectively attached to any one of the plurality of attachment portions 20. More specifically, the auxiliary tool 3 can be attached to the first attachment portion 20a, and the auxiliary tool 3 can be attached to the second attachment portion 20b.

[0056] In the examples shown in FIGS. 1 to 4, the support 2 (more specifically, the side surface 230 of the first table 23) has a plurality of attachment portions 20 including the first attachment portion 20a and the second attachment portion 20b so that an operator can perform (1) a step of attaching the auxiliary tool 3 to the first attachment portion 20a (see FIG. 2), (2) a step of rotating the support 2 in a first rotation direction R1 about a first axis AX1 using the auxiliary tool 3 attached to the first attachment portion 20a (see FIGS. 2 and 3), (3) a step of removing the auxiliary tool 3 from the first attachment portion 20a (see FIG. 4), (4) a step of attaching the auxiliary tool 3 to the second attachment portion 20b, and (5) a step of further rotating the support 2 in the first rotation direction R1 about the first axis AX1.

[0057] As illustrated in FIG. 4, it is preferable that the operator can visually recognize both the first attachment portion 20a and the second attachment portion 20b through the opening OP so that it is easy to attach the auxiliary tool 3 removed from the first attachment portion 20a to the second attachment portion 20b.

[0058] As illustrated in FIG. 16, a straight line connecting the first attachment portion 20a and the first axis AX1 is defined as a first straight line LN1, and a straight line connecting the second attachment portion 20b and the first axis AX1 is defined as a second straight line LN2. When viewed in the direction along the first axis AX1 (more specifically, in plan view), the angle β formed between the first straight line LN1 and the second straight line LN2 is, for example, 120 degrees or less, 90 degrees or less, or 72 degrees or less. When the angle β is sufficiently small, the operator can visually recognize both the first attachment portion 20a and the second attachment portion 20b simultaneously through the opening OP.

[0059] The support 2 (for example, the first table 23) may have three or more attachment portions 20 to which the auxiliary tool 3 can be attached. In the example shown in FIG. 16, a plurality of attachment portions 20 including a first attachment portion 20a, a second attachment portion 20b, and a third attachment portion 20c are arranged on the side surface 230 of the first table 23.

[0060] Three or more attachment portions 20 to which the auxiliary tool 3 can be attached may be arranged at equal angular intervals around the first axis AX1. For example, when N is defined as any natural number of 3 or more, N attachment portions 20 including the first attachment portion 20a and the second attachment portion 20b may be arranged at intervals of (360 / N) degrees around the first axis AX1. N is, for example, 3, 4, 5, 6, 7, or 8. N may also be 9 or more.

[0061] In the example shown in FIG. 19, the pallet PT is removable from the first table 23. Further, the pallet PT can be attached to the first table 23.

[0062] As illustrated in FIG. 16, the first table 23 may include a first gripping member 24 (for example, the first chuck 24c) that grips the pallet PT, and a gripping member driving device 25 (for example, a hydraulic device) that drives the first gripping member 24. The gripping member driving device 25 moves the position of the gripping portion of the first gripping member 24 to a gripping position for gripping the pallet PT.

[0063] In the example shown in FIG. 19, the pallet PT is removed from the first table 23 by being lifted upward. More specifically, the pallet PT is removed from the first table 23 by being lifted upward by the pallet moving device 80 in a state where the gripping of the pallet PT by the first gripping member 24 is released.

[0064] (Door 11) As illustrated in FIG. 1, the setup station 10A may include a door 11 capable of opening and closing the opening OP. The door 11 is position-changeable between an open position Q1 (see FIG. 1) and a closed position Q2 (see FIG. 20). When the door 11 is in the open position Q1, the operator can access the setup area RG1 from the outside of the setup area RG1 through the opening OP. When the door 11 is in the open position Q1, the workpiece W may be carried into the setup area RG1 from the outside of the setup area RG1 through the opening OP.

[0065] In the example shown in FIG. 20, when the door 11 is in the closed position Q2, the jig 3 is removed from the support 2. In this case, the distance between the side surface of the support 2 and the door 11 can be made relatively smaller compared to the case where the handle for rotating the support 2 is constantly fixed to the side surface of the support 2. Therefore, the size of the door 11 can be reduced, or the setup station 10A can be made more compact.

[0066] As illustrated in FIG. 20, the setup station 10A may include a door moving device 14 for moving the door 11. The door moving device 14 moves the position of the door 11 between the open position Q1 and the closed position Q2.

[0067] (Setup station 10A) The setup station 10A constitutes a part of the machine tool. In other words, the setup station 10A is a setup station for the machine tool.

[0068] (Workpiece setup) The workpiece setup may include attaching the workpiece W to the support 2. More specifically, the workpiece setup may include attaching the workpiece W to the pallet PT supported by the first table 23. The workpiece setup may include rotating the support 2 about the first axis AX1 using the auxiliary tool 3 after the workpiece W is attached to the support 2.

[0069] In this specification, the processed workpiece (more specifically, the workpiece processed by the tool T held by the processing head 71 described later) is defined as the processed workpiece Wp. An example of the processed workpiece Wp is shown in FIG. 21.

[0070] The workpiece setup may include removing the processed workpiece Wp from the support 2. More specifically, the workpiece setup may include removing the processed workpiece Wp from the pallet PT supported by the first table 23. The workpiece setup may include rotating the support 2 that supports the processed workpiece Wp about the first axis AX1 using the auxiliary tool 3. In this case, the operator can perform the removal operation of the processed workpiece Wp at a position close to the opening OP.

[0071] The workpiece setup may include inspecting the processed workpiece Wp supported by the support 2.

The input device 96 is not limited to the display 962 with a touch panel. For example, the control device 9 may include an input device 96 such as a button, a switch, a lever, a pointing device, a keyboard, etc., and a display for displaying data input to the input device 96 or other information. The memory 92 stores a machining program 921 and data necessary for machining the workpiece W (for example, workpiece data 926 including the shape data of the workpiece W and the machining position data of the workpiece W). The control device 9 generates control commands (for example, the first movement command SA1, the first gripping command SA2, the second gripping command SA3, etc., described later) by executing the machining program 921 stored in the memory 92.

[0103] The control device 9 controls the moving device 72 (more specifically, the machining head moving device 72a). More specifically, the control device 9 transmits the first movement command SA1 to the moving device 72, and the moving device 72 that receives the first movement command SA1 relatively moves the machining head 71 with respect to the workpiece W.

[0104] The control device 9 may control the gripping member driving device 25. More specifically, the control device 9 transmits the first gripping command SA2 to the gripping member driving device 25, and the first gripping member 24 that receives the first gripping command SA2 grips the pallet PT (or the second pallet PT2). Further, the control device 9 transmits a first release command to the gripping member driving device 25, and the first gripping member 24 that receives the first release command releases the gripping of the pallet PT (or the second pallet PT2).

[0105] The control device 9 may control the second gripping member driving device 75. More specifically, the control device 9 transmits a second gripping command SA3 to the second gripping member driving device 75, and the second gripping member 74 that receives the second gripping command SA3 grips the second pallet PT2 (or the pallet PT). Further, the control device 9 transmits a second release command to the second gripping member driving device 75, and the second gripping member 74 that receives the second release command releases the gripping of the second pallet PT2 (or the pallet PT).

[0106] The control device 9 may control the pallet moving device 80. More specifically, the control device 9 transmits a group of control commands SA4 to the pallet moving device 80, and the pallet moving device 80 that receives the group of control commands SA4 moves the pallet PT from one of the setup area RG1 and the machining area RG2 to the other of the setup area RG1 and the machining area RG2. The pallet moving device 80 that receives the group of control commands SA4 may move one of the pallet PT and the second pallet PT2 from the setup area RG1 to the machining area RG2, and move the other of the pallet PT and the second pallet PT2 from the machining area RG2 to the setup area RG1.

[0107] The control device 9 may control a coolant supply device 77 that supplies coolant liquid to the workpiece W and / or a table rotating device 78 that rotates the second table 73.
