TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal stamping apparatus for manufacturing a wide plate by bonding a surplus material having a random width in a horizontal direction in a plate manufacturing process.
[0002]
[Prior art]
In the existing horizontal stripping device, the veneer is transported in a direction perpendicular to the fiber direction, the end faces are butted, and the veneer is bonded by hot-melt adhesive yarn or an adhesive. , 2), and a composer system in which a horizontal strip is performed through a tunnel of a press. There is also a method that goes one step further to increase productivity by using high frequency in the same method (for example, see Patent Document 3). The production capacity of each press method is about 10 to 15 cubic meters per day. The biggest problem is that the recent glue has been changed to water-based isocyanate (water-based vinyl urethane) without formalin, and the bonding speed has increased. However, it reacts with iron and hardens, making cleaning inside the press very difficult. Will be difficult.
[0003]
In the lumbering process of the lumber (see Fig. 4), extra wood with a random width is generated. In order to make effective use of this material, it is necessary to bond it in the horizontal direction (horizontal strip) to produce a wide board. FIG. 3 shows a conventional side-to-side (width-to-side) press. The surplus wood a is conveyed to a side-to-side press by a conveyor chain conveyor (1), and is glued to a bonding surface by a sizing machine (3). Each time it is inserted into the horizontal press by the insertion press d 'using the hydraulic cylinder, and it takes about 20 minutes in the press.
[0004]
Furthermore, if the material is thin, it is unstable and broken when the material is put up. The maintenance of the press, which caused the glue to run out, took enormous time and labor.
[0005]
In the case of an existing press, the press length has a limit, and the average is about 5 to 6 m. For example, when the width is 70 mm, a constant pressure in the press is required for 20 minutes, and the press length is 6 m In the case of, about 85 pieces require 20 minutes. Therefore, the cycle time can be shortened by raising the temperature in the press to 60 to 70 ° C because only 4.25 bottles can be supplied per minute, but only 6 to 8 tubes can be supplied on average.

FIG. 1 shows the basic structure of a side-to-side (width-to-side) press, in which a pallet b for installing a side-to-side wood a is inserted into the inclined width-to-side press in a stable state of the wood a. The wood a placed on the pallet b is pressed laterally by the lateral pressure press c, and is pressed and bonded in the adjacent contact direction by the hydraulic press d. The width peeling press has a guide roller e on a surface for supporting and guiding the pallet b, and a driving roller h formed at right angles to the supporting and guiding surface and driving the pallet b in the press. Have.
The guide roller e and the drive roller h can be replaced by a pallet b guide / conveying means such as a chain conveyor means. Since it takes 3 to 3.5 minutes per cycle, 8 to 10 presses are arranged and inserted into the press in a cycle of about 30 minutes. The work is placed on a dedicated pallet and moved in consideration of maintenance due to sticking out of glue. If the pallets become very dirty, replace the spare pallets regularly and clean the collected pallets.
