Abstract

PURPOSE:To make it possible to manufacture a composite plate material with small material cost and installation cost by producing a gap on the outer periphery side of the facing end face to a neighboring piece of each piece arranged laterally on a curved transferring path, sticking the outer periphery face of each piece to an adhesive tape to connecting these pieces together and fixing the inner periphery face of each piece on a plain face plate while the tape is straightly extended. CONSTITUTION:Rectangular wooden pieces 21 are laterally placed on the upper face of a guide rail 15 and each piece is transferred to the right hand side by means of a transferring roller 25. The neighboring piece 21 reaching the curved part 15a produces a gap (A) on the outer periphery side of its facing end face and the upper face of each piece is connected with an adhered adhesive tape 18 under this condition. Then, the tape 18 is cut by means of a cutter 290 and pieces 21b of the both left and right ends of the obtd. group 22 of the pieces are pulled to the left and right hand sides to extend straightly the tape 18. Under this condition, the lower face of each piece is fixed on a plain surface plate 23 and the upper and lower faces are finished by means of a sander 24 and the adhesive tape 18 is removed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for manufacturing a composite board material, in which a large number of rectangular pieces are fixed to a flat surface board to obtain a thick board material such as a floor board. It is.

(Prior Art) In general, this type of composite plate material is made to have a small bending rigidity and to be easily adapted to a mating member by fixing each piece to a surface plate with a small gap between them.

By the way, as a conventional technique, there is a manufacturing method shown in FIGS. 4 to 6.

First, as shown in FIG. 4, a large number of rectangular wooden pieces 3 are laid out side by side and placed on the guide rail 1.

This guide rail 1 has a horizontal inlet part (left part) la and an unloading part (right part) lc, and a curved part 1b that curves downward along the guide roller 2 in the middle. Each piece 3 is transferred to the right along.

Further, below the carrying-in portion 1a of the guide rail 1, a circular saw 4, a wire supply roll 5 wound with an aluminum wire 5a, and a disk-shaped press-fit disk 6 are arranged in order toward the right. In addition, a sump 7 is provided below the unloading section IC. These circular saw 4° wire rod supply roll 5, press-fit disk 6, and sump 7 are as follows:
They are provided in pairs in parallel at each longitudinal end of the nine pieces 3 placed on the guide rail 1.

Then, when each piece 3 is transferred to the right by the guide rail 1, a pair of grooves 3a are first formed at both ends of the lower part of the piece 3 using the circular saw 4 at the loading section 1a of the guide rail 1, Next, the wire rod 5a fed out from the wire rod supply roll 5 is press-fitted into each groove 3a by a press-fitting disk 6,
As a result, the pieces 3 are connected to each other in a state where they are spread side by side.

Next, the connected pieces 3 are compressed by the curved portion 1b of the guide rail 1 and the guide roller 2 to bend into an arc shape, thereby forming a predetermined gap (a) between the pieces 3.

Next, at the carry-out section 1c of the guide rail 1, the wire rod 5a is cut by a cutter every time a predetermined number of pieces 3 pass, thereby obtaining a piece group 8.

Next, as shown in FIG. 5, the lower surface of the piece group 8 is placed and fixed on a flat surface plate 9, and as shown in FIG. Finish to ensure thickness and surface accuracy.

(Problems to be Solved by the Invention) The above-mentioned conventional one forms a concave groove 3a on the back surface of the piece,
By embedding the wire rod 5a in the groove 3a, the pieces 3 are connected to each other, so that thin pieces cannot be used, and the wire rod 5a and the groove 3a are connected to each other.
This method requires a circular saw 4 and the like for forming, which has the drawback of increasing material and equipment costs.

An object of the present invention is to obtain a novel method for manufacturing a composite plate material that eliminates the above-mentioned drawbacks.

(Means for Solving the Problems) In order to achieve the above object, the present invention is configured as follows.

That is, a large number of rectangular pieces are spread side by side and transported laterally, a curved transfer path that curves in a direction perpendicular to the transport direction is provided in the middle of this transfer direction, and each piece arriving at the curved transfer path is Adhere adhesive tape to the outer circumferential surface of each piece in a continuous manner in the horizontal direction of each piece, extend the adhesive tape in a straight line, and fix the lower surface of each piece fixed to the adhesive tape to a flat surface plate. It is configured to do this.

(Function) Since the present invention has the above-mentioned configuration, the outer circumferential sides of the opposing end surfaces of the pieces arriving at the curved transfer path are separated from each other, and each piece is fixed to the outer circumferential surface in this separated state. They will be connected to each other by adhesive tape.

Then, by extending the adhesive tape in a straight line and fixing the inner circumferential surface of each piece fixed to it to a flat surface plate, each piece is fixed to the surface plate while maintaining a predetermined gap from each other. That will happen.

(Implementation A Embodiments of the present invention will be described below based on the drawings.

In the drawings, Fig. 1 is a schematic side view showing the state in which adhesive tape is attached to the pieces, Fig. 2 is a cross-sectional side view showing the state in which the pieces connected by the adhesive tape are fixed to the surface plate, and Fig. 3 The figure is a cross-sectional side view showing the finished state.

In FIG. 1, reference numeral 15 denotes a guide rail, and this guide rail 15 extends horizontally from the loading section (left section) 15a to the right, and curves upward along guide rollers 16 in the middle. Part + 5 feeding path) In order, the unloading part (right part) 15C should be connected to the above curved part! b
It is formed horizontally from the top to the right.

A tape roll 17 wrapped with adhesive tape 18 such as gummed tape and a pressure roller 19 are arranged radially outward of the curved portion 15b of the guide rail 15, and
A cutter 20 is placed above 5c.

These tape roll 17, pressure roller 19, cutter 20
are provided in pairs in parallel in the width direction of the guide rail 15.

A large number of rectangular wooden pieces 21 are placed side by side on the upper surface of the guide rail 15, and each piece 21 is guided by a transfer roller 25 arranged on the left side of the guide rail 15. Transfer it to the right along the rail 15.

Then, the adhesive tape 18 drawn out from the tape roll 17 is continuously supplied to the upper surface (outer peripheral surface) of each piece 21a that has arrived at the curved portion 15b of the guide rail 15, and the upper surface of the piece 21a is Adhere pressure to the

In this case, the adjacent pieces 21 that have arrived at the curved portion 15b have a predetermined gap (
A) occurs, and in this state each piece 21 is connected to each other by the adhesive tape 18 fixed to its upper surface.

Next, at the unloading section 15c of the guide rail 15.

Each time a predetermined number of pieces 21 pass, the cutter 20 cuts the adhesive tape 18 to obtain a piece group 22.

Next, as shown in FIG. 2, the pieces 21b at both left and right ends of the piece group 22 are pulled in the left-right direction to extend the adhesive tape 18 in a straight line, and in this state, each piece 2
After placing the lower surface (inner circumferential surface) of 1 on a flat surface plate 23 and fixing it, the upper and lower surfaces are finished with a sump 24, the adhesive tape 18 is removed, and a predetermined Make it thick.

(Effects of the Invention) As is clear from the above description, the present invention creates a predetermined gap on the outer periphery of the opposing end surfaces of adjacent pieces in a curved transfer path for each piece laid out side by side. Then, adhesive tape was fixed to the outer circumferential surface of each piece to connect them to each other, and this adhesive tape was extended in a straight line to fix the inner circumferential surface of each piece to a flat surface plate.

A predetermined piece can be used regardless of its thickness, and it can be manufactured at low cost.
