Description

[Detailed description of the invention] The present invention relates to a machine that obtains a board of a constant width by cutting both the left and right edges of a raw wood cut to a predetermined thickness. This method is characterized in that the plate material is obtained by cutting both ears to the minimum width of the material.

Therefore, in the present invention, a pair of fluid cylinders 13 and 13' are provided on a long machine board table 15, and a bent portion is attached to the table 15 via a connecting piece 28 at the tip of the piston rod 14 of each cylinder. A pair of centering arms 16, 16' and 16" each having an abutment rod 43 erected at the tip thereof,
1611/ are connected in series to form a pair of centering mechanisms A and A'
, one centering mechanism A' is located near the open end of the table 15, the other centering mechanism A is located on the cutting mechanism B side, and a fluid cylinder 17 is disposed at the bottom of the table 15, and the piston rod 18 of the centering mechanism A' is located at the cutting mechanism B side. A single-shaped lever 2 whose respective bent portions are pivotally connected to the table side via a pair of intermediate pieces 29 at the tip.
Lock it at one end of 0.20', and use a single-shaped lever 20.20
The other end has a connecting piece 30.30' and is connected to a pair of slider panels 31.31'. Circular saws 19 and 1 arranged opposite to each other and each connected to a prime mover.
In the machine for cutting both side edges of a wooden board, in which the cutting mechanism B is constructed by providing the cutting mechanism B, a pinion 32 and a rotary ring 33 are pivotally connected to a shaft 42 that stands up from the machine stand C. 33 is provided with gear-shaped recesses 33' at regular intervals on the circumferential surface, and a limit switch 34 with an operating piece 34' in contact with the concave part 33' is disposed on the machine base C.
A pair of centering arms 16j on the side of the cutting mechanism B, with a rank 40 that engages with the cutting mechanism B, is fixed to one of the slider panels 31 to form a cutting allowance mechanism.

A connecting rod 35 is connected to one side of the table 16, and an actuator 37 with another limit switch 36 attached to its tip is locked so that it can slide on a guide rod 38 extending from one side of the table 15. This is a wooden board edge cutting machine in which a contact piece 39 that contacts the limit switch 36 of the actuator 37 is installed on the sliding machine board 31 on the side where the actuator 37 is installed.

In the figure, reference numeral 8 indicates a plate material, and 41 indicates an automatic feeding mechanism for the plate material a.

Since the present invention has the above structure, by placing the plate material a on the table 15 with the narrow part facing the cutting mechanism B,
By means of the plate a, the starting switch is actuated to operate the fluid cylinder 13, 13', and the centering arm 16. By moving the provided contact rod 43 toward the center of the plate material a at a constant speed and compressing the plate material,
Centering is performed by placing it at the center of the table 15.

At this time, as the contact rod moves, the actuator 3 disposed at the tip of the centering arm 16' is moved through the connecting rod 35 connected to the centering arm 16'.
7 slides on the guide rod 38 and advances toward the center of the plate material, and the limit switch 36 provided on the actuator comes into contact with the contact piece 39 provided on the slide machine panel 31, and the fluid cylinder 1
7 is actuated, a pair of single-shaped levers connected to the piston rod 18 are rotated, and a sliding panel disposed opposite to the machine stand C is moved toward the center of the machine body.

Further, at the position where each abutment rod 43 of the centering arm abuts against the plate material, the movement of the actuator 37 also stops, and as a result, the abutment piece 39 of the sliding machine which was cooperating with the plate material is released from the limit switch 36. However, at this time, the distance between the circular saws 19 and 19' provided opposite to each of the sliding machine panels and the width of the narrow part of the plate material are
The pieces are the same and the cutting allowance is not enough, so the above-mentioned piece 3
9 is removed from the limit switch 36, that is, before the electric circuit is opened, the rotating wheel 33 is rotated via the pinion 32 by a rack 40 to which the sliding panel 31 is fixed, and the operating protrusion 34 of the limit switch 34 is rotated. The cutting distance is obtained by advancing the sliding machine until the point ' is brought into contact with a recess 33' provided in the rotary wheel 33 and the limit switch is turned off.

After that, the limit switch 36 is removed from the contact piece 39.

After centering the plate material under the cover and positioning the circular saw inside the narrow width of the plate material by the cutting distance, release the clamping pressure only on the centering arm, feed the plate material with the feed roller, and use the circular saw to cut the material. After cutting both ears to obtain a plate, the circular saw is returned to its original position using a pass limit switch (not shown).

By repeating the above operations, a plate material is obtained.

Therefore, according to the present invention, the centering of the material and the interval adjustment between the circular saws are automatically performed, and the contact rod 43 comes into contact with the material so as to sandwich the material, and then the circular saw 19.19' Since the cutter enters toward the center, the plate material can be reliably cut by an amount greater than the width of the material, and unnecessary cutting of the material due to excess cutting allowance can be minimized.
