[0013]
A pair of centering devices 44 are provided so as to hold the log 1 at two locations, and each centering device 44 has substantially the same configuration. Each centering device 44 includes a lever 56 as a stopper member, and the lever 56 is located on the back side of the log 1 with respect to the clamp devices 40 and 41. One end of each lever 56 can contact the side surface of the log 1, and the other end is pivotally supported by a swing pin 59 via a connecting member 58 with respect to the log holding member 46 and is swingably attached. Yes. A connecting portion 62 that protrudes from the side surface is provided at a substantially intermediate position of each lever 56, and a pair of wires 60 that are ascending restriction members that stop the lever 56 that rises as the log holding member 46 rises at a fixed position. One end of each is connected to the connecting portion 62. Each lever 56 is pulled by a tension spring 61 in a direction away from the log 1. The other end of the tension spring 61 is locked by a locking member 63 fixed to the connecting member 58, and elastically biases the lever 56 so that the lever 56 comes into contact with the contact member 65 and stops.
[0014]
The pair of wires 60 are arranged substantially symmetrically, and the other ends thereof are turned in the horizontal direction by rollers 64 at the bottom of the main body 20 and are respectively connected to the sides of the main body 20. The other end of each wire 60 is connected to the main body 20 via a tension spring 68 provided on the attachment member 66. Further, a stopper piece 70 is fixed in the vicinity of the connecting portion of each wire 60 to the main body 20, and a stopper plate 72 is provided in the vicinity of the roller 64 in contact with the stopper piece 70 to stop the advancement of the wire 60. ing. The position of the stopper piece 70 with respect to the wire 60 is attached to be adjustable. The position of the stopper piece 70 is such that the tip of the lever 56 abuts against the log 1 in a state where the lever 56 is raised together with the log holding member 46, and the longitudinal center axis of the log 1 is the rotation center of the clamp devices 40 and 41. This is a position where the stopper plate 72 comes into contact with the substantially matched state.
[0015]
The log holding member 46 includes a pair of holding portions 75 opened in a V shape, and an attachment member 76 to which the holding portion 75 is fixed and the rod 82 of the air cylinder 76 is fixed. An upper end of a guide post 78 provided in the vertical direction is fixed. The guide post 78 is fitted into a guide cylinder 80 that guides and holds the sliding, and the guide cylinder 80 is fixed to the main body 20. The lifting device 48 that raises the log holding member 46 includes an air cylinder 74 that is arranged in the vertical direction, and the tip of the rod 82 of the air cylinder 74 is fixed to the connecting member 58 of the log holding member 46.
[0016]
In the operation of the shiitake log automatic inoculation apparatus of this embodiment, first, the log 1 is placed on the pair of holding portions 75 of the log holding member 46, and the start button of this apparatus is pushed. Then, the log holding member 46 is raised by the air cylinder 74 and the wire 60 is pulled. When the stopper piece 70 of the wire 60 comes into contact with the stopper plate 72, the wire 60 does not move any further, so that the position of the connecting portion 62 of the lever 56 is fixed at that position, as shown in FIG. Even in this state, the rod 82 of the air cylinder 74 tends to rise, so that the holding portion 75 and the connecting member 58 of the log holding member 46 rise, and the lever 56 swings clockwise in FIG. When the tip of the lever 56 comes into contact with the side surface of the log 1, the lever 56 does not swing any further, and the ascent of the log holding member 46 is restricted and stopped by the wire 60.
[0017]
As shown in FIG. 3, the centering by this mechanism is such that in the state where the raising of the lever 56 is regulated, the rising end of the raw wood holding member 46 becomes lower as the diameter of the raw wood 1 increases. Since the position of the connecting portion 62 of the 56 is the central portion of the lever 56, the log holding member 46 is interposed via the swing pin 59 with a negative value substantially equal to the value at which the tip of the lever 56 varies depending on the thickness of the log 1. Regulate the ascending position. Therefore, regardless of the thickness of the log 1, the center in the longitudinal direction can be brought almost to the center of rotation of the clamping devices 40 and 41.
[0018]
Thereafter, the log 1 is clamped by the clamping devices 40 and 41, and the log holding member 46 is lowered. In this state, the movable frame 16 is moved along the drive rails 18 and 19 by the driving device 17, and the drilling machine 10, the inoculating machine 12, and the wax sealing machine 14 puncture and inoculate the log 1 with a predetermined pitch. , Seal. At this time, the log 1 is rotated at a predetermined angle by the clamping devices 40 and 41 and is inoculated over the entire circumference of the log 1.
[0019]
When the inoculation work is completed for the whole circumference of the log 1, the clamp devices 40 and 41 are moved forward in the horizontal direction by the holding and moving device 42, and the clamp is released. The inoculated log 1 is dropped on the log holder 84 of the main body 20 and temporarily held. A guide plate 86 for guiding the raw wood 1 dropped from the clamping devices 40 and 41 is provided above the raw wood placing portion 84 so that the raw wood 1 is securely placed on the raw wood placing portion 84.
[0020]
In the automatic inoculation apparatus for shiitake log of this embodiment, the centering device 44 is located on the back side of the log holding member 46, and the apparatus can be downsized without obstructing the removal of the log 1 after inoculation. Further, the log 1 is rotated around the longitudinal axis, and each drilling machine 10, the inoculator 12, and the wax sealer 14 are moved along the log 1 while moving the movable frame 16 with respect to the main body 20. Therefore, the main body 20 can be reduced in size, and the range of the movable part as the whole apparatus can also be reduced.
[0021]
The centering device of the present invention is not limited to the above embodiment, and the wire may be any member that restricts the intermediate portion of the lever, which is a stopper member, to a predetermined position, and may be a member fixed to the main body. .
[0022]
【The invention's effect】
The shiitake log automatic inoculation device of the present invention can accurately center the shiitake log which is curved or of different thickness, has a simple structure, and can be downsized. In particular, by configuring the stopper member with a lever and interlocking with the lifting device, the mechanism can be simplified and highly reliable. Further, since the centering device is positioned on the back side of the raw wood with respect to the clamp device, it is easy to install and take out the raw wood, and further contributes to downsizing of the device.
