The moving member 40 is fixed to an operating portion 52 of an air cylinder 50 provided in the vertical direction, and is provided so as to be movable in the vertical direction, and the moving member 38 is also moved via the pinions 42, 44. Are provided so as to be movable in directions opposite to each other. Here, the moving distance of the moving members 38, 40 is 1: 2, which is the same as the radius ratio of the pinions 42, 44.
It is. This is the holding member 3 which opened the log 34 at 60 degrees.
This is because the center of the log is always located at the holding center 54 by the holding member 30 that presses the wood 2 vertically downward. That is, the line from the contact holding the log 34 on the holding member 32 opened at 60 degrees to the holding center 54 is inclined 60 degrees with respect to the vertical direction, and one apex angle is a right triangle with 60 degrees. Since the ratio of the length of the shorter side and the hypotenuse across the 60 ° apex angle is 1: 2, in order to keep the position of the clamping center 54 unchanged, the moving member 38,
This is because 40 must be moved at a ratio of 1: 2.

As shown in FIGS. 1 and 5, the drill device 14 is fixed to a holding member 22 and is movably provided in a horizontal direction. The drill device 14 is located at the center of a pair of positioning members 18 and 19. A centering device 20 having a pair of positioning members 18 and 19 is provided with a rack 6 on each side of a pinion (not shown).
The positioning members 18 and 19 are fixed to the racks 60 and 61, respectively. The pinion is mounted so as to be always positioned on the center axis of the drill 16 of the drill device 14, and the positioning members 18 and 19 are always fixed to the drill 16 by the pinion and the racks 60 and 61.
Are moved in the horizontal direction by the same distance in opposite directions about the center axis of the center. The positioning member 18 is attached to the operating part of the air cylinder 62, and is provided to be vertically movable in the vertical direction. Further, the positioning member 19 is attached to the operating portion of the air cylinder 64 and is driven in the horizontal direction, and the positioning member 18 is also equidistant in the opposite direction to the positioning member 19 by the rack 60 via the rack 61 and the pinions 42 and 44. Only be driven. Further, the drill device 14 is also attached to the operating portion of the air cylinder 74 and is provided so as to be vertically movable.

The holding member 22 is provided with a shiitake mushroom inoculation device 26 at a predetermined interval from the drill device 14, and the shiitake mushroom in the tank 24 is driven into a hole formed in the log. A driving device 66 and an air cylinder 68 for driving the driving device 66 are provided.

The operation of the automatic positioning apparatus according to this embodiment will be described below. First, the log 34 is placed on the holding member 32 of the mounting member 10, and the start button of the apparatus is pressed. Then, the holding member 32 moves up and the holding member 30 moves down. At this time, as described above, since the ratio of the moving distance between the holding member 30 and the holding member 32 is 1: 2, the thickness of the log 34 is reduced at the position where the log 34 is held between the holding member 30 and the holding member 32. Regardless, the center of the log 34 is located at a predetermined center of the mounting member 10. At this time, at the position where the moving member 40 to which the holding member 32 is attached is stopped, the thickness of the log 34 is detected by the position detecting device 48 such as the photoelectric sensor or the proximity sensor provided on the dog 46. This thickness is determined by the position or number of the position detecting devices 48 facing the moving member 40.
Is detected in a stepwise manner in accordance with the position on the dog 46 of. Thereafter, the log 34 is horizontally moved to the holding position of the clamp device 12, and the clamp device 12 is operated to hold both ends of the log 34 from both sides.

The clamp device 12 holding the log 34 is
It is horizontally moved below the drill device 14 by a driving device (not shown). Thereafter, the positioning member 18 descends, and the positioning members 18 and 19 approach each other in the horizontal direction by the air cylinder 64, and sandwich the log 34. Thereby, each drill 16 is positioned at the center of the predetermined position of the log 34. At this time, the log 34 is curved in the middle,
Since the holding member 22 can move in the horizontal direction, the drill 16 moves along the curve of the log 34 and is always positioned at an intermediate position between the positioning members 18 and 19 while being sandwiched between the positioning members 18 and 19. And the drill 16 descends,
A hole is made in a predetermined position of the log 34 by the number of the drills 16 and ascends.

Then, the clamp device 12 moves below the shiitake fungus implantation device 26 while holding the log 34. The implantation device 26 implants a predetermined amount of Shiitake fungi in the tank 24 into the hole formed in the log by the driving device 66. Thereafter, the clamping device 12 moves below the drill device 14 again.

Here, the clamp device 12 rotates by a predetermined angle, and the drill 1
The log 34 is moved in its axial direction by a distance of about half the spacing between the six. The rotation angle is an angle determined by the thickness of the log 34, and is an interval at which Shiitake fungi are planted. The thickness of the log 34 is, as described above, the position detection device 4.
8 and rotated by an angle corresponding to a predetermined detection position. The reason for moving the log 34 in the axial direction is to implant the Shiitake fungi on the surface of the log 34 in a staggered manner in order to increase the spacing between the Shiitake fungi to be implanted. Thereafter, similarly to the above, the positioning member 18 is lowered, and the positioning members 18 and 19 are brought closer to each other by the air cylinder 64 to sandwich the log 34. Then, a hole is made by the drill 16 and the log 34 is moved again below the implanting device 26 to implant Shiitake fungi.

The above operation is repeated, for example, 4 to 10 times in accordance with the thickness of the log 34, holes are formed at predetermined intervals on the surface of the log 34, Shiitake fungi are implanted, and then the clamping device 12
Is released, and the log 34 is released. Then, the log 34 rolls down the discharge path 70 and is stocked in the take-out unit 72.

According to the automatic positioning processing apparatus of this embodiment, the center of rotation in the axial direction is automatically set for the shiitake mushroom wood 34 having an unspecified thickness and shape, and the thickness is ranked. When drilling holes with the drill 16, the holes can be automatically drilled toward the center. Also, when the Shiitake fungus is implanted, the Shiitake fungus can be accurately driven into the drill hole.
