The pin extending directions Dp of the pins 21 of the plurality of support cylinders 20 are aligned with each other when the casing 25 is fixed to the cylinder base 11. That is, the pin extending direction Dp in each pin 21 is the same direction. In addition, the pin extending direction Dp in each pin 21 may not be the same direction. Further, the positions of the pins 21 of the plurality of support cylinders 20 in the pin extending direction Dp are the same as each other in a state where the pins 21 are located at the maximum projecting positions.

  The cylinder base 11 is formed with a flow path 12 that receives the fluid from the fluid line 42 of the fluid supplier 40 and guides the fluid to the inlet 28 of each casing 25 in the plurality of support cylinders 20. The flow path 12 is connected to a fluid line 42 of the fluid supplier 40, and a main flow path 13 that receives fluid from the fluid line 42, and a branch from the main flow path 13 to each of the plurality of support cylinders 20. And a branch flow path 14 connected to the inflow port 28. For this reason, it is not necessary to provide the fluid line 42 connected to the cylinder base 11 for each of the plurality of support cylinders 20, and the fluid line 42 can be integrated.

  The support device includes the support 10, the support moving mechanism 54, the work gripper 52, the gripper moving mechanism 53, and the base 51 among the components of the processing apparatus M described above.

  Next, a processing procedure for processing the blade material 1a into the blade 1 using the processing apparatus M described above will be described according to the flowchart shown in FIG.

  First, as shown in FIG. 1, the support tool 10 is arranged at a predetermined position on the base 51 (S1: initial preparation step). In the initial preparation step (S1), the support tool 10 is fixed to the support tool moving mechanism 54 of the processing machine 50. Next, when the support tool moving mechanism 54 is driven and the blade material 1a is processed in the processing step (S7) described later, all of the plurality of pins 21 in the support tool 10 can come into contact with the blade material 1a. This support 10 is arranged at the position. When the support tool 10 is disposed at a predetermined position, in this embodiment, the pin extending direction Dp of each pin 21 of the plurality of support cylinders 20 is the Z direction, that is, the vertical direction.

  Next, the blade material 1a is gripped by the workpiece gripper 52 of the processing machine 50 (S2: workpiece gripping step). In this work gripping step (S2), a blade root forming portion (blade fixing forming portion) 3a which is an end portion in the longitudinal direction Dw of the blade material 1a and becomes the blade root (blade fixing portion) 3 is gripped.

  Next, the gripping machine moving mechanism 53 is driven, and the blade material 1a gripped by the work gripping machine 52 is disposed at a predetermined position for processing in the processing step (S7) described later together with the work gripping machine 52 (S4: Work placement process). When the wing material 1a is arranged at a predetermined position, in the present embodiment, the longitudinal direction Dw of the wing material 1a becomes the Y direction. That is, the longitudinal direction Dw of the blade material 1a is a horizontal direction perpendicular to the Z direction, and is a direction perpendicular to the pin extending direction Dp of each pin 21 in the support 10 arranged at a predetermined position.

  In the process of the workpiece placement step (S4), the contact seats 24 of the plurality of pins 21 are sequentially brought into contact with the downward surface of the blade body forming portion 2a to be the blade body 2 in the blade material 1a. When the contact seat 24 of the pin 21 contacts the surface of the blade material 1a, the follower mechanism 31 of the support cylinder 20 moves the position of the surface of the blade material 1a in the pin extending direction Dp to move the pin 21 in the pin extending direction Dp. Follow the position (S5: pin following step). During the pin following step (S5), the contact seat 24 of the pin 21 continues to contact the surface of the blade material 1a.

  After the work placement step (S4) is completed, the fluid is supplied from the fluid supplier 40 to the support tool 10. This fluid flows into the fluid chambers 29 of the plurality of support cylinders 20 through the main flow path 13 and the branch flow path 14 of the cylinder base 11, and elastically deforms the collet 36 toward the inner peripheral side. As a result, the collet 36 holds the proximal end portion of the pin 21 and restrains the pin 21 so as not to move in the pin extending direction Dp (S6: pin restraining step).

  In the supporting step (S3) for supporting the blade material 1a, the workpiece placement step (S4), the pin following step (S5) and the pin restraining step (S6) described above are executed. In this support step (S3), the contact seats 24 of all the pins 21 in the support 10 are in contact with the downward surface of the wing body forming portion 2a, and the support 10 supports the wing material 1a from below.

  After the support step (S3) is completed, the tool driving mechanism 55 having the machining tool 59 mounted on the spindle 55s is driven to rotate the machining tool 59 and the tool moving mechanism 56 to drive the blade material 1a. The upper part of the wing body forming part 2a is processed (S7: processing step (S7)).

  During the processing step (S7), the blade material 1a is supported by the support 10 while being gripped by the workpiece gripper 52. During the processing step (S7), the support 10 need not be moved at all, but may be moved. For example, when the processing tool 59 and the support tool 10 do not face each other in the pin extending direction Dp during the process of moving the processing tool 59 during processing, the support tool 10 may be moved so that both face each other. At this time, the movement of the processing tool 59 is stopped, the processing is once stopped, and the pin 21 restraint of the support tool 10 is released, and then the support tool 10 is moved so as to face the processing tool 59. Then, after restraining the pin 21 of the support tool 10, the processing with the processing tool 59 is started again.

  Upon completion of this processing step (S7), the upper part of the blade body forming portion 2a in the blade material 1a is processed. The blade material 1a in which the upper part is processed becomes the blade intermediate product 1b (see FIG. 2).

  Next, an intermediate preparation step (S9) is performed in order to process the lower part of the blade body forming portion 2a in the blade intermediate product 1b. In this intermediate preparation step (S9), the gripper moving mechanism 53 is driven to move the blade intermediate product 1b gripped by the workpiece gripper 52 together with the workpiece gripper 52 upward, so that the support 10 and the blade Release the intermediate product 1b. When the support tool 10 and the wing intermediate product 1b are separated from each other, the pin 21 restraint of the support tool 10 is released. Next, the gripper moving mechanism 53 is further driven, and the blade intermediate product 1b gripped by the workpiece gripper 52 together with the workpiece gripper 52 is reversed about the gripping axis Ag of the workpiece gripper 52. As a result, the lower part in the blade intermediate product 1b becomes the upper part, and the upper part becomes the lower part. Next, when the support tool moving mechanism 54 is driven and the blade intermediate product 1b is positioned at a predetermined position suitable for processing the unprocessed portion that is the upper portion of the blade intermediate product 1b, a plurality of the support tool 10 are provided. The support tool 10 is moved to a position where the pin 21 can come into contact with the lower surface of the blade intermediate product 1b. Thus, the intermediate preparation process (S9) is completed.

  When the intermediate preparation step (S9) is completed, the above-described support step (S3) is performed as shown in FIG. That is, the gripper moving mechanism 53 is driven, and the blade intermediate product 1b gripped by the workpiece gripper 52 together with the workpiece gripper 52 is disposed at a predetermined position for processing in the subsequent processing step (S7) (S4). : Work placement process). Also in this work arrangement step (S4), in the present embodiment, the longitudinal direction Dw of the blade intermediate product 1b is the Y direction.

  In the process of the workpiece placement step (S4), the contact seats 24 of the plurality of pins 21 are sequentially brought into contact with the downward surface of the blade body forming portion 2a to be the blade body 2 in the blade intermediate product 1b. Even in the work placement step (S4), when the contact seat 24 of the pin 21 contacts the surface of the blade material 1a, the follower mechanism 31 of the support cylinder 20 determines the position of the surface of the blade material 1a in the pin extending direction Dp. The position of the pin 21 in the pin extending direction Dp follows the movement (S5: pin following step). Since the downward surface in the blade body forming portion 2a in the blade intermediate product 1b is a surface that has already been processed, a three-dimensional curved surface is formed. However, in the execution of the pin following step (S5), all of the contact seats 24 of the plurality of pins 21 come into contact with the downward surface of the blade intermediate product 1b. After the work placement step (S4) is completed, a fluid is supplied from the fluid supply device 40 to the support tool 10, and all of the plurality of pins 21 in the support tool 10 are restrained so as not to move in the pin extending direction Dp (S6: pin). Restraint process).

  After the support step (S3) is completed, the tool driving mechanism 55 is driven to rotate the machining tool 59 and the tool moving mechanism 56 is driven to move the upper portion of the blade body forming portion 2a in the blade material 1a. Processing (S7: processing step (S7)).

  If the processing of the wing body 2 is completed at the completion of this processing step (S7) (YES in S8), a series of processing ends. In addition, when the above processing is rough processing and further finishing processing is performed, the support step (S3) and the processing step (S7) are executed again through the intermediate preparation step (S9). In the intermediate preparation step (S9), the processing tool 59 is replaced as necessary.
