Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a deburring device for plywood.

[Background technology]

Decorative plywood is usually manufactured by pasting boards onto a base plate. At that time, the burrs on the mounting plate that protruded from both sides of the base plate were removed by sanding or the like.

However, as shown in FIGS. 1A and B, the burrs 3 on both sides of the plate 2 attached to the base plate 1 are either upward or downward, so the conventional sanding method does not It was difficult to completely remove 3.

[Purpose of invention]

The object of this invention is to provide a deburring device that can completely and automatically remove burrs from both sides of a plywood sheet without any manual effort.

[Disclosure of invention]

The deburring device of this invention includes a plywood conveyance guide in which burr holders are provided on both sides at intervals equal to the width of the plywood, and burr holders are provided in front of the burr holders and below the plywood conveyance path to the guide. a first air outlet that blows upward the downward burrs on both sides of the plywood and places them on the burr holder; The second part that holds the burr on the burr cradle
This includes an air outlet, and a cutting blade provided behind the air outlet to cut off the burr.

According to this invention, a first air outlet is provided in front of the burr holder to blow the burrs upward, so downward burrs that do not rest on the burr holder are removed from the first air outlet.
The air can be blown upward by the air outlet and placed securely on the burr holder. Therefore, there is no problem in conveying the plywood to the burr receiving stand.

Further, since a second air outlet for blowing air downward is provided above the burr holder, upward burrs floating from the burr holder can be pressed against the burr holder. Therefore, the burrs can be reliably removed by the cutting blade on the burr holder without any manual effort.

An embodiment of this invention will be described with reference to FIGS. 2 to 5. In FIG. 2, reference numeral 4 denotes a guide made of monomer casting nylon or the like, and burr holders 5 are integrally provided on both sides of the plate-like body 4a. The height of each burr holder 5 from the plate-like body 4a is equal to the thickness of the plywood base plate, and the interval between the burr holders 5 is equal to the width of the plywood. Place the burrs protruding from both sides of the plate onto the burr holder.

A first air outlet 6 is provided in front of each burr holder 5. This air outlet 6 is located below the guide 4 and blows air upward.
Further, a second air outlet 7 and a circular saw 8 for removing burrs are arranged on the burr holder 5 along the plywood transport direction. Furthermore, behind the guide,
Finishing belt sanders 9 are provided which obliquely abut on both sides of the plywood being transferred via the guide 4.

Next, the operation of this embodiment will be explained in Figures 3 to 5.
This will be explained with reference to the figures. As shown in FIG.
When the plywood 10 is continuously transferred, air is blown upward from the first air outlet 6 provided in front of the burr receiver 5 on both sides of the guide 4 to lift the downward burrs 11 on both sides of the plywood 10 upward. In this state, the burr 11 is placed on the burr holder 5 as shown in FIG. Further, as shown in FIG. 5, the second air outlet 7 provided above the burr holder 5 blows air downward to press the upward burr 11 onto the burr holder 5. Then, the burr 11 is cut by about 1 to 2 mm using a circular saw 8 provided behind the second air outlet 7.
Cut out leaving the width. The circular saw 8 rotates at a rotation speed that is 1.1 to 1.2 times faster than the conveyance speed of the plywood 10. The plywood 10 that has left the guide 4 is finished by removing the remaining burrs 11 with a width of 1 to 2 mm using the abrasive paper (or abrasive cloth) of the belt sander 9 disposed on both sides.

[Effect of idea]

According to this invention, upward or downward burrs can be automatically removed without any manual effort.
Continuous processing of plywood becomes possible.
