[0002]

2. Description of the Related Art A log cut into a certain length is carried in by a carry-in means, and the carried log is supported by a holding and rotating means. A piece hole into which a piece is driven is formed in a scattered point shape, and subsequently, a mushroom fungus piece is driven into each piece hole by a piece driving means,
After that, there is already an automatic mushroom fungus piece driving machine that releases the support of the raw wood by the gripping and rotating means, and carries out the processed raw wood to the outside by the carry-out means.

[0003]

The conventional automatic mushroom fungus piece driving machine described above is large-scale, complicated and expensive even if used alone. By using cheap machines,
In some cases, the whole work is desired efficiently and efficiently. The present invention is an apparatus developed to meet such a demand.

[0004]

In order to achieve the above object, according to the present invention, there is provided a carrying means for carrying a log cut to a certain length to a first specific position, and a log taken into the specific position. In the process of moving the log to the second specific position, rotating and holding the log at the second specific position, a hole into which mushroom fungus pieces are driven into the periphery of the log is scattered by a drilling device equipped with a plurality of drills. Frame hole forming means, and a carry-out means for carrying out the log having the frame hole formed by the piece hole forming means out of the machine. The guides are formed at appropriate intervals, and the guides are mounted on each guide so as to be vertically displaceable in a state where the guides are urged toward the support position of the raw wood. Attached to a swingable shaft and the blade is directed to the supporting position Along with the drill, a guide member having a triangular recess formed in the same part as the drill is attached so as to be displaceable in the direction of the cutting tool center line in a state in which the biasing force toward the support position is applied, and corresponds to each guided body. In addition to providing a spring attitude holding mechanism that holds the drill in a substantially vertical position with the elasticity of the spring, and a drill movement suppressing means that suppresses the movement of each drill to the second specific position side None, and the unloading means are a downward slope for supporting the log released at the second specific position, a feeder for moving the log supported on the downward slope in the downward direction, and the feeder. It is configured to be transported upward and diagonally upward and then discharged outside the machine after being automatically transported.

[0005] The triangular concave portion of the guide member is pressed against the peripheral surface of the raw wood held at the second specific position. At this time, the apex of the triangular concave places the drill tool at the center of the width of the peripheral surface of the raw wood. Since it acts so as to guide, the piece hole is formed at an optimum position on the peripheral surface of the log.

According to the present invention, when a log is supplied to the loading means, the loading means loads the unprocessed raw wood to a specific position, and subsequently, the piece hole forming means automatically forms a piece hole, and thereafter unloads. The means carries out the treated log outside the machine. Therefore, there is no need for a mechanism for performing the process of driving the mushroom pieces, and only the process of forming the piece holes in the raw wood is inexpensively and continuously performed.

The unloading means according to the present invention is configured such that the log is automatically conveyed obliquely upward and then discharged outside the machine. According to this, a large number of treated logs are piled up in large quantities at the discharge position.

[0008] In particular, the carrying-out means is a downward slope for supporting the log released at the second specific position, a feed device for moving the log supported on the downward slope in the downward direction, and the feeder. The apparatus is provided with an upwardly inclined conveying device that transports the log sent out by the device diagonally upward and then discharges the log outside the machine, so that the log released at the second specific position has a downward slope. And it is reliably and quickly carried out of the machine without being damaged through the inclined conveying device, and the quality and efficiency of the raw wood drilling process are improved.

Further, in the raw wood drilling device according to the present invention,
While forming a plurality of vertical guides at appropriate intervals,
The guided object is placed in each guide part at the support position of the log (second specific position)
It is installed so that it can be displaced up and down in a state biased toward, and
A base end portion of a drill is pivotally mounted on each guided body so that its cutting tool is directed to the specific position, and a guide member having a triangular recess formed in the same part as the drill is moved to a second specific position. In addition to being freely displaceable in the direction of the cutting tool center line in the state where the biasing force is applied, a spring attitude holding mechanism is provided for each guided body that holds the corresponding drill approximately vertically with the elasticity of the spring. Further, the movement of each drill to the second specific position side is controlled.

According to this, while the guided body is moving in the specific direction in the up and down direction, the triangular dent portion of each guide member is pressed by the appropriate pressure against the peripheral surface of the log which is horizontally held at the second specific position. At this time, since the apex of the triangular recess acts to guide the drill tool to the center of the width of the peripheral surface of the raw wood, the guide member is guided and displaced in the circumferential direction by the action of the spring attitude holding mechanism. The piece hole is formed at an optimum position on the peripheral surface of the log so as to be oriented appropriately.
