As shown in FIG. 11, in the blade material 100, one feather portion (feather valve) 104 spreads on one side of a half-turned blade shaft 102. As shown in FIG. 11 (b), the blade width of the blade shaft 102 of the blade material 100 gradually narrows from one end, which is the root side of the bird's blade F, to the other end side, which is the tip side, in a side view. It is like that. As shown in FIG. 12B, the blade shaft 102 is formed so as to protrude from the surface formed by the feather portion 104 to one side when viewed in the axial direction from the end portion side of the blade shaft 102. . Note that the protruding direction of the blade shaft 102 from the surface of the feather portion 104 varies depending on the difference between the right and left portions when the bird's blade F is vertically half-turned from the blade shaft, the difference between the left and right blades of the bird, and the like.

  As shown in FIGS. 1 and 2, the support device 12 is a support means for supporting the blade material 100. In the present embodiment, the two support devices 12 are arranged side by side symmetrically so that the two blade materials 100 can be supported simultaneously. The support device 12 supports, for example, the feather portion 104 portion of the blade material 100 and does not cover the blade shaft 102 portion to be molded. Specifically, the support device 12 includes a base portion 18 that is linked to a moving device 14 described later, and a clamping device 20 that is provided on the base portion 18. The base unit 18 has, for example, a base body formed in a deformed hexagonal shape in which two corners of a quadrangle are obliquely cut off in a plan view, and the slider of the moving device 14 disposed below the base body 18. 36 and the adjustment unit 37 are connected.

  As shown in FIGS. 3, 4, and 5, the clamping device 20 detachably holds the feather portion 104 of the blade material 100 and supports the blade shaft 102 portion close to the blade shaft forming machine 16 side. . In the present embodiment, the clamping device 20 includes, for example, two clamping members that are detachably clamped in a state where the blade material 100 is laid down and the longitudinal direction of the blade shaft 102 is made substantially horizontal. In the present embodiment, the direction along the blade axis 102 in a state where the blade material 100 is supported by the support device 12 is defined as the front-rear direction FR. That is, the vertical direction in FIG. 1 is the front-rear direction FR, the lower side of the figure is the front direction, the upper side of the figure is the rear side, and the left-right direction in the figure is the left-right direction. The two clamping members include, for example, a fixed clamping plate 24 fixed on the inclined portion 22 on the base portion 18, and the blade material 100 in close proximity to the fixed clamping plate 24 in cooperation with the fixed clamping plate 24. And a movable clamping plate 26 that is detachably mounted. The fixed clamping plate 24 and the movable clamping plate 26 are each made of a thin strip-like metal plate on one side (in the front-rear direction FR), and are attached on the inclined portion 22. The fixed clamping plate 24 and the movable clamping plate 26 are provided such that the length in the front-rear direction is longer than the length of the blade material 100 and the length in the left-right width direction is larger than the area of the feather portion 104 of the blade material 100. It supports so that the feather part 104 may be covered when it pinches | interposes with the plates 24 and 26. FIG. The fixed clamping plate 24 and the movable clamping plate 26 are connected to each other through the fixed portion 27 between the front end portions thereof, and the other end side of the movable clamping plate 26 is opened and closed like a leaf spring. The movable clamping plate 26 is provided so that the urging force always acts in the direction in which the movable end opens, that is, in the direction in which the movable end is separated from the fixed clamping plate 24, by the elastic restoring force of the plate spring-like metal plate. ing. As shown in FIG. 3, in the open state, the fixed clamping plate 24 and the movable clamping plate 26 have an elongated triangular shape in which the space between them is gradually narrowed toward the rear side. Thus, for example, a narrow portion between the sandwich plates 24 and 26 corresponding to the gradually narrowing shape of the blade shaft 102 of the blade material 100 (see FIG. 11B). Since the blade material 100 can be installed on the fixed clamping plate 24 while being inserted in the blade, the blade material 100 can be accurately and smoothly installed at a predetermined position of the clamping device.

  As shown in FIG. 12, for example, in the blade material 100, the blade shaft protrudes in one direction from the surface of the feather portion 104 when viewed in the direction of the blade shaft 102, and the feather portion 104 is predetermined when attached to the shaft of the arrow. Fixed at an angle of In the present embodiment, as shown in FIG. 5, the clamping device 20 on which the feather portion 104 is mounted is inclined by the inclined portion 22, and the clamping device 20 is a blade shaft forming device in consideration of the mounting angle to the shaft. 16 is supported in a state where the processing position of the blade shaft 102 with respect to 16 is suitably set. For example, in FIG. 5, the clamping device 20 is installed such that the blade shaft 102 protruding from the surface of the feather portion 104 faces downward and supports the feather portion 104 in an inclined state. The inclined portion 22 does not necessarily have to be provided, and an angle or the like may be appropriately set according to the type of blade, or may be provided with a reverse inclination. Moreover, it is good also as comprising so that the angle of the support apparatus 12 can be changed.

  As shown in FIGS. 4 and 5, the clamping device 20 is provided with an operation unit 28 for operating attachment / detachment of the feather portion 104 of the blade material 100 to / from the clamping device 20. For example, the operation unit 28 is engaged with the upper surface side of the movable clamping plate 26 to press the movable clamping plate 26, and the first link body 32 is linked between the pressing member 30 and the inclined portion 22. And a handle 34 that links the link body 32 and operates the pressing member 30 in a substantially vertical direction, and a second link body 35 that links the handle 34 and the inclined portion 22. The pressing member 30 is formed, for example, with a length slightly shorter than the movable clamping plate 26, and is supported on the clamping plate 26 in a state where the longitudinal direction coincides with the longitudinal direction of the movable clamping plate 26 and is supported by the first link body 32. Has been placed. The first link body 32 is connected to two positions at which the two link bodies are separated from each other in the longitudinal direction of the pressing member 30 and is rotatably connected to the inclined portion 22 via a pivot. Each of the two handles 34 has one end thereof connected to the first link body 32 via a pivot, and is rotatably connected to the second link body 35 via a pivot. The second link body 35 is connected to the inclined portion 22 by a pivot.

  As shown in FIG. 5 and FIG. 6, the operation unit 28 of the clamping device 20 operates the two handles 34 in the vertical direction by hand, respectively, via the first link body 32 and the second link body 35. The pressing member 30 is moved up and down and is held at the upper and lower positions. When the pressing member 30 is lowered by the operation of the handle 34, the movable clamping plate 26 is pushed down to approach the fixed clamping plate 24 side, and the clamping plates are closed to clamp the feather portion 104 of the blade material 100. And the sandwiched state is maintained. In the sandwiched state, while supporting the feather portion 104 of the blade material 100, the blade shaft 102 is exposed to the outside and supported so as to be close to the blade shaft forming device side 16. Since the first link body 32 acts on the pressing member 30 at two positions along the longitudinal direction of the pressing member 30, the blade member 100 held between the holding plates 24 and 26 can be stably and reliably supported. . On the other hand, when the pressing member 30 is moved upward by the operation of the operation unit 28, the movable clamping plate 26 opens the movable end side by its own restoring force, and the blade material 100 can be easily attached and detached. Note that the clamping device 20 may have a configuration in which, for example, two blade members are closely spaced apart from each other in a parallel state so that the blade material can be attached and detached. The operation unit 28 is not limited to one operated by hand, and may be configured to open and close the two clamping members by electricity, hydraulic pressure, air pressure, or the like.

  As shown in FIGS. 1 and 2, the moving device 14 is a moving unit that moves a predetermined moving path in a state where the blade material 100 is supported. In the present embodiment, the moving device 14 includes, for example, a linear reciprocating mechanism that linearly moves the support device 12. The moving device 14 is provided long so as to form a linear moving path RT toward the front-rear direction FR, which is a direction substantially along the length of the blade shaft 102 of the blade material when the blade material 100 is supported by the support device 12. ing. For example, the moving device 14 is arranged below the two support devices 12 and moves each support device 12 straight along the linear movement route RT. The moving device 14 includes, for example, a known linear reciprocating mechanism that linearly moves the slider 36 with an actuator or the like. The moving device 14 includes a slider 36 that is slidable in the longitudinal direction and a driving device (not shown) that linearly moves the slider 36. The supporting device 12 connected to the slider 36 under the control of the unit is linearly moved integrally in the longitudinal direction. In the initial state, for example, the moving device 14 supports the support device 12 at the front end position P1 of the linear movement route RT by the control unit, and turns on the operation switch 38 electrically connected to the control unit. The support device 12 is controlled to reciprocate once along the longitudinal direction to the other end side (the rear end position P2 in FIG. 1). The moving device 14 may be configured to be moved by any other driving source such as an electric type, a mechanical type, a hydraulic type, a pneumatic type, or the like. Preferably, since a load is generated from the blade shaft forming device when the blade shaft is processed, it is preferable to generate a driving force that can reliably support and move the blade material against the load.

  The blade shaft forming device 16 is a processing means that is disposed in the movement path of the support device 12 of the moving device 14 and performs a forming process so that the blade shaft 102 portion is in close contact with the shaft surface of the arrow.

The first and second rotating grindstone portions 44 and 46 are made of a thick disc-shaped grinding wheel that rotates around the vertical rotation shafts 44 a and 46 a, and the outer periphery faces the linear movement path RT of the support device 12. As the supporting device 12 supporting the blade material 100 moves, the blade shaft 102 is shaved at the outer peripheral portion. The first and second rotating grindstone portions 44 and 46 are rotationally driven by a rotational driving device 48 including a motor and gears that drive and transmit rotational force to the rotational shafts 44a and 46a, respectively. When the support device 12 moves along the linear movement path RT, the first and second rotating grindstone portions 44 and 46 have outer peripheral portions that come into contact with the blade shafts 102 of the rotating grindstone portions 44 and 46 with respect to the moving direction. Rotate in the opposite direction. Only a part of the first and second rotating grindstone parts 44 and 46 including the part that contacts the blade shaft 102 of the blade member 100 supported by the support device 12 is exposed to the outside, and the other part is accommodated inside the cover 50.
