2. Description of the Prior Art To date, the preferred apparatus for aligning wooden plaques, which aligns the wooden plaques as described above, does not exist to the best of the applicant's knowledge.

[0003]

SUMMARY OF THE INVENTION According to the present invention, a wooden plate-like material sent one by one on a conveyor with its front or back face up is erected such that the side edge or edge is up. In addition, it is an object of the present invention to provide a new wooden plate-like body aligning device for aligning the respective wooden plate-like bodies so that the front surface or the back surface thereof is in contact with each other.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an apparatus for aligning a wooden plate as described below.

[0005] (1) An alignment plate extending forward from below a front end of a feed conveyor for feeding a wooden plate-like body one by one with its front surface or back surface facing upward is provided. The feed conveyor has an inclined portion extending obliquely upward from below a front end thereof, and a horizontal portion connected to the inclined portion. The alignment plate has a plurality of through grooves formed in the front-rear direction and vertically penetrating the alignment plate. Each through groove is formed continuously from the rear edge of the alignment plate or from the vicinity of the rear edge to a part of the horizontal portion, and an endless annular body such as a belt and a chain is provided between the plurality of conveyor wheels below the alignment plate. An endless annular body of the aligning conveyor is disposed so that the endless annular body of the aligning conveyor is substantially parallel to the inclined portion from near the trailing edge of the inclined portion of the alignment plate to near the boundary between the inclined portion and the horizontal portion. Ascending part close to the part The forward part near the boundary between the horizontal part and the horizontal part is a downward part that is inclined obliquely downward, and the endless annular body has a number of claws aligned in the horizontal direction corresponding to each through groove of the alignment plate and predetermined in the front-rear direction. When the alignment conveyor is rotated, the endless annular claws protrude above the respective through-grooves from the rear edge or near the rear edge of the alignment plate and protrude above the respective through-grooves when the alignment conveyor is rotated. In the aligned plate, move forward along the inclined portion of the alignment plate, gradually descend from the vicinity of the boundary between the inclined portion and the horizontal portion of the alignment plate, enter each through groove of the alignment plate, and reach below the alignment plate. An apparatus for arranging a wooden plate-shaped body (claim 1).

In this specification including the claims, "front" means the direction of feed of the conveyor, that is, the right side in FIGS. 1 and 2, and "rear" means the direction opposite to "front". That is, the left side in FIGS. 1 and 2 is referred to. Also,
The “lateral” refers to a horizontal direction perpendicular to the front-rear direction, that is, the vertical direction in FIG.

(2) A guide plate for guiding a wooden plate is disposed between the front end of the feed conveyor and the rear edge or near the rear edge of the alignment plate, and the guide plate is provided with the guide plate. The through grooves penetrating back and forth are formed corresponding to the through grooves of the alignment plate.

(3) A guide brush for guiding a wooden plate is disposed immediately before the front end of the feed conveyor and the guide plate (claim 3).

(4) An overturn prevention brush for preventing the wooden plate-like member from overturning is disposed above the vicinity of the boundary between the inclined portion and the horizontal portion of the alignment plate in a state of being close to the alignment plate.
(Claim 4).

(5) The wooden board is a kamaboko board, and the feed conveyor is a kamaboko board which is configured to select and remove only a kamaboko board having a defect such as a node, a tar, a mold from the kamaboko board. This is a conveyor for feeding only the defective tubs after sorting and removing in the automatic sorting apparatus (claim 5).

[0011]

According to a first aspect of the present invention, the woody plate-like bodies sent one by one on the feed conveyor with the front side or the back side facing upward are fed from the front end of the feed conveyor. With the side edge or edge of the wooden plate-shaped object facing upward, the wooden plate falls near the rear edge or near the rear edge of the alignment plate. Thus, since the claw of the endless annular body protrudes above each through groove in a state where the claw of the endless annular body is aligned in the lateral direction at or near the rear edge of the alignment plate, each claw dropped on the inclined portion of the alignment plate. The woody plate leans against a row of claws located immediately after each woody plate and is held upright with the side edges or edges up. Each wooden plate-like body is pushed by the nail while leaning on the immediately succeeding row of nails, and climbs the inclined portion of the alignment plate. When the wooden plate reaches the vicinity of the boundary between the inclined portion and the horizontal portion, the nail immediately after the wooden plate gradually starts to descend, and the nail gradually pushes the lower portion of the wooden plate.
Eventually, when the claws enter the through-grooves of the alignment plate and reach below the alignment plate, the wooden plate-shaped member is no longer pushed by the claw, and the horizontal portion of the alignment plate stands upright with the side edge or the edge up. Stop on. In this manner, the wooden plate-like bodies are successively carried on the horizontal portion of the alignment plate, and a large number of wooden plate-like bodies stand up with their side edges or edges up, and the front or back surface of each wooden plate-like body. Are aligned in contact with each other. The wooden boards aligned in this state are gradually pushed by the subsequent wooden boards and move forward.

[2] A device for aligning a wooden plate-like body according to a second aspect of the present invention, wherein the wooden plate-like body is guided by a guide plate from the front end of the feed conveyor to the rear edge or near the rear edge of the aligning plate when falling from the front end of the feed conveyor. The alignment plate is guided and reliably falls to the rear edge or near the rear edge of the alignment plate in a predetermined state with the side edge or the end edge facing upward. In addition,
When the alignment conveyor is rotated, the claw of the endless annular body penetrates through the through groove of the guide plate and the through groove of the alignment plate and protrudes above the rear edge or near the rear edge of the alignment plate.

According to a third aspect of the present invention, the wooden plate-like object dropped from the front end of the feed conveyor is guided by the guide brush and the guide plate, and has a predetermined side edge or edge. In this state, it will surely fall to the rear edge or near the rear edge of the alignment plate.

According to a fourth aspect of the present invention, the wooden plate-like body stands upright near the boundary between the inclined portion and the horizontal portion of the alignment plate. At this time, the wooden plate-like body is prevented from overturning. The brush is prevented from falling forward by contact with the brush.

[5] An apparatus for aligning a woody plate-like body. After the automatic screening apparatus for a kamaboko board sorts and removes a kamaboko board having defects such as knots, tar, mold, etc., a flawless kamaboko board becomes a side edge. Or, they are automatically aligned in a state of standing upright with their edges upside down and the front or back surface of each Kamaboko plate being in contact with each other. That is,
This alignment device automates the operation of aligning the kamaboko boards in a predetermined state, and greatly reduces the time, labor and labor required for the operation. It should be noted that, as an example, the Kamaboko boards arranged in a predetermined state are packaged and then shipped.
