Description

  In the present invention, after drying and cutting a single plate obtained by cutting a log with a rotary lace, the single plate is stacked and bonded through a thermosetting adhesive, and the number of stacked layers is repeated by shifting the bonding stepwise. The present invention relates to a laminate material manufacturing method and a laminate material manufacturing apparatus for manufacturing a continuous laminate material.

In order to manufacture the laminated material, an LVL (Laminated Veneer Lumber) manufacturing apparatus as schematically shown in FIG. 1 has been proposed.
The apparatus is provided with a first hot press X, a second hot press Y, and a third hot press Z, each of which is provided with a single plate feeding device (not shown), and each hot press is moved up and down. It consists of a pair of movable hot plates X1, Y1, and Z1.
When bonding the single plates, first, apply the adhesive to the single plate A on one side of the two single plates A shown by drawing the diagonal lines supplied by the single plate feeder, and match the fiber directions. The stacked single plates A are conveyed between the first hot presses X, and heated and pressed by the first hot press X to bond the two single plates A together. Next, after the pressing of the first hot press X is released, the two bonded single plates A (hereinafter referred to as the bonded single plate A) are conveyed between the second hot press Y. During this conveyance, two single plates B, which are supplied by a single plate feeder on both the front and back sides of the bonded veneer A and are applied with an adhesive on the surface of the bonded veneer A, are indicated by a single line. The plate A and the fiber direction are aligned and overlapped. In this state, the sheet A is conveyed between the second hot presses Y, and heated and pressed to bond the single plate B to both the front and back sides of the bonded single plate A.
Next, after releasing the pressure of the second hot press Y, the four bonded single plates A and B (hereinafter referred to as an adhesive single plate AB) are conveyed between the third hot presses Z. In the middle of this conveyance, two single plates C supplied by a single plate feeding device on both the front and back sides of the bonded single plate AB, and drawn with diagonal lines with an adhesive applied to the surface of the bonded single plate AB are shown as a single plate. A and fiber directions are made to coincide with each other, and in this state, they are conveyed between the third hot presses Z, and heated and pressed to bond the single plates C to both the front and back sides of the bonded single plate AB.
By repeating these operations, the single plates are sequentially bonded and transported so that there are six layers in the thickness direction, and the LVL is manufactured. As shown in FIG. 1, each single plate is orthogonal to the thickness direction of the LVL. The veneers A, B, and C that are adjacent to each other in the direction are in a state where the ends of the fiber direction are in close contact with each other, and the seam between the close end and the end of the close is in the thickness direction. It is supplied and bonded by a single plate feeding device so as to form a shape. The reason for bonding in a stepped manner is that when the seam is bonded as a position aligned in a straight line in the thickness direction, when the obtained LVL is subjected to bending force so as to bend in the fiber direction, the seam This is because the stress concentrates on this point and is easily broken.
Plywood Industry 70 Published November 1972 Editor Japan Wood Processing Technology Association Plywood Section

However, in the apparatus, in order to form the stepped shape, in each of the two single plates to which the adhesive to be bonded in each hot press is applied, the single plate positioned at least on the lower side in the thickness direction is transferred to the hot press. The pressure from the hot press does not act in the vicinity of the upper end in the conveying direction, that is, the portion surrounded by the circle R. On the other hand, heat from the hot press is transmitted to the enclosed portion. Usually, in order to bond the veneer well with an adhesive, it is necessary to simultaneously apply an appropriate temperature and pressure to the entire surface of the veneer to which the adhesive has been applied. The veneer does not adhere well, resulting in poor adhesion, and the obtained LVL becomes a defective product.
In this case, if the width of the enclosed portion R in the left-right direction in FIG. 1 is reduced, the portion that causes poor adhesion is reduced, but the seam is arranged in a straight line in the thickness direction. Thus, the obtained LVL was easy to break, and as a result, the above-mentioned adhesion failure could not be avoided.

  The present invention has been invented in order to solve the above-described conventional problems, and the problem is that the entire surface of the single plate with adhesive is directly or indirectly by a heated hot plate. An object of the present invention is to provide a method for manufacturing a laminated material that is bonded by pressure welding and an apparatus for manufacturing the laminated material.
