Description

DETAILED DESCRIPTION OF THE INVENTION [Objective] It is an object of the present invention to provide an apparatus for manufacturing dyed veneers in a labor-saving manner for use in manufacturing laminated decorative veneers.

[Background Art] The manufacturing process of a conventional laminated decorative Il board was roughly as follows.

■ Process low-grade logs into veneers of desired thickness using rotary lace. Wind up the veneer into a roll.

■1 Cut the small plates of rotary lace material according to the product dimensions.

■ Color the cut veneer material to the desired brand color by immersing it in a dye or other dye solution. Next, dry as necessary.

■ Colored veneers are laminated with an adhesive interposed between them, and are then sandwiched between molds with uneven surfaces and pressed together to form a flitch.

(2) Next, the flitch is sliced using a slicing device to form a laminated decorative veneer.

In the above process, steps 1 to 2 involve the installation and removal of parts in each process, resulting in time loss due to work in progress at each stage and yield loss due to damage to materials that occurs during the installation and removal of parts. A decrease was observed.

Regarding the processing speed during the process, (p and ■ could be processed at approximately the same speed, but for It took several hours (1 to 4 hours) to complete the process, making it difficult to carry out a series of continuous steps.

This invention was made in view of the above circumstances.

"Disclosure of the Invention" The present invention provides a dyed veneer manufacturing apparatus capable of processing the above-mentioned steps 1 to 2 as a series of steps. An explanation will be given below based on drawings shown as examples.

The figure is a schematic diagram of the device according to the invention. Here, 1 is raw wood, 2 is a cutter for rotary lace, 3 is a coloring liquid tank, 4 is a roll for applying coloring liquid, 5 is a roll for transporting veneer, 6
is a veneer cutting device, 7 is a liter for loading medium plates, 8 is a stopper when loading veneers, 9 is a veneer cutting table, 10 is a colored and cut veneer, 11 is a microwave generator (magnetron) ), 12 is a microwave irradiation tank.

Next, the operation of the device will be explained. First, log l is attached to the device. Log 1 is supported by its end face,
And it is rotationally driven by a predetermined driving means. Then, a cutter 2 for rotary lace is applied to this log 1 to perform rotary lace.

Regarding this point, the conventional law applies. The rotary-laced veneer is sent in its long form to a coloring liquid coating roll 4, and is coated with a coloring liquid. The coloring liquid application roll 4 at this time is not intended to be limited (any other means may be used as long as it can be applied. The coloring liquid application roll 4 is supplied with the coloring liquid from the coloring liquid tank 3. The veneer coated with the liquid is sent to the microwave irradiation tank I2, and while being sent by the conveying roll 5, the colored liquid penetrates into the veneer using microwaves generated by the microwave generator 11. When the molecular motion of I & becomes intense due to microwave irradiation, the middle plate reaches a temperature due to the moisture in the veneer, and when it leaves the microwave irradiation tank 12, it has an approximately appropriate moisture content.Microwave Irradiation tank 12
The exiting veneer is cut into a desired width using a cutting knife 6 on a cutting table 9F. By performing microwave irradiation in this manner, the coloring process, which conventionally required 1 to 4 hours, can be performed in several tens of minutes.

The cut veneer is loaded on a loading lifter 7. Here, the loaded 1m10 is aligned by the stopper 8. The loading lifter 7 descends as the veneers are loaded, so that the cutting table 9 and the upper position of the loaded veneers 10 are aligned with each other.The device described above is an example of the invention. In short, the apparatus according to the present invention includes means for continuously cutting out veneers from raw wood, means for continuously applying a colored liquid to the cut out veneers, next means for irradiating this with microwaves, and then It is only necessary to have a means for cutting the f+. In addition to the above, known means may be applied to mechanical elements necessary to realize the device according to the present invention.

[Effects] Since this invention has the above-mentioned welfare, it has the effect of eliminating the work-in-progress that occurs in each of the conventional rotary lace, cutting, and coloring processes, and further reducing damage to the veneer between processes. . Microwave irradiation shortened the coloring process.
