DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing a throated finger joint material used as a longitudinal joining material for wood.

[0002]

2. Description of the Related Art A longitudinal joint material for joining two pieces of wood in the longitudinal direction includes a scarf joint material formed by forming a step surface that complements each other at a kiguchi, and a glue cut at a right angle to a lumber joint. There is a finger joint material formed by forming and joining a so-called uneven surface having a sawtooth shape, that is, a finger.

As a modified example of the finger joint material, as shown in FIG.
9b are formed with inclined surfaces 100a, 100b at the respective kerfs, and fingers 101 are formed along the inclined surfaces 100a, 100b.
a and 101b are formed, and there is a thrust finger joint material in which these are joined by butt. The thrust finger joint material has a feature that the bending strength, particularly the impact bending strength, can be increased as compared with the above-described joint materials.

[0004] Conventionally, the processing of the finger of the slope finger joint material is performed in the following procedure. The finger cutting cutter is the same as that used for manufacturing a normal finger joint material, and a rotary blade having a finger-shaped longitudinal section is used. The installation angle of the wood having the inclined surface formed at the tip is fixed on the table of the cutting device so that the inclined surface is parallel to the feed direction of the finger cutting cutter. Next, the axial position of the wood is fixed so that the cutting depth of the finger cutting cutter is appropriate, and the cutting device is driven to form a finger on the inclined surface of the wood opening.

[0005] The other wood to be joined to the wood is processed in the same procedure, but in order to make the unevenness of both fingers complement each other, the other wood is placed on the table of the cutting device. When placed on the wood, a liner or the like having a thickness corresponding to a half pitch of the fingers is inserted under the wood.

[0006]

As described above, in the conventional processing of fingers of a slope finger joint material, two pieces of wood to be joined are processed at different timings. In many cases, the installation angle and the axial position of the wood on the table of the cutting device are shifted.

[0007] If the installation angle of either one of the two woods on the table of the cutting device is shifted, the slope of the finger formed on the joint surface of the two woods is different, so that the sloped finger joint material is not used. There is a problem that it is slightly bent at the joint surface and cannot be straightened.

If the axial position of the wood on the table is displaced and the cutting depth of the finger cutting cutter is insufficient, the complementation at the joining surface of the two woods is incomplete.
There is a problem that the joining strength is greatly reduced. Also, when the cutting depth is excessive, there is a problem that the load on the cutting device increases and the yield of wood decreases.

Further, in the above-mentioned conventional processing method, since it is necessary to adjust the installation angle and the axial position on the table of the cutting device for each piece of wood, there is a problem that this setting requires a great deal of trouble. .

It is an object of the present invention to provide an apparatus for manufacturing a thrust finger joint material capable of processing and joining a joining surface with high precision and efficiency.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, an apparatus for manufacturing a throat finger joint material according to the present invention fixes two pieces of wood on a single axis at a required interval, and After the fingers have been cut, two wood fixing mechanisms for bringing the two woods closer together and pressing them together, and between the two wood fixing mechanisms, advance and retreat at a predetermined inclination angle to the axis on which the wood is fixed. A moving finger cutting cutter, wherein the finger cutting cutter cuts a sloping finger at the tip of one piece of wood during forward movement, and cuts at a tip of the other piece of wood at the time of backward movement. To cut a slump finger that is half a pitch shifted from the slump finger
Means for moving the finger cutting cutter relative to the opening was provided.

That is, in the apparatus for manufacturing a throat finger joint material according to the present invention, two pieces of wood, each of which has an inclined surface formed beforehand, are fixed on one axis, and are parallel to the inclined surface of the edge crossing this axis. The finger cutting cutter is moved forward and backward along the same axis, and the finger is cut at the tip of one piece of wood when moving forward, and at the tip of the other piece of wood when retreating. Of fingers can be formed.

Further, the fingers to be cut are shifted from each other by half a pitch when the finger cutting cutter is advanced and retracted, so that the two woods are simply clamped as they are, and the joint surface between the two is completely complemented. You can make them compete with each other. Therefore, by applying an adhesive to one of the joining surfaces, bringing both woods close together and pressing them,
It is possible to manufacture a straightened finger joint material with high joint strength.

[0014] The moving axis of the cutter may be inclined in two directions with respect to the fixed axis of the wood.
A thrust finger joint material whose joint surface is inclined in two axial directions can be manufactured.

[0015] When pressing the two wood pieces, the apparatus having the two wood fixing mechanisms is attached to a pedestal mounted on a base, a timber pedestal provided on the pedestal, and a pressing and pressing means for pressing and fixing the wood. And a method in which at least one of the wood placing tables is slidable along a fixed axis of the wood.

[0016] In order to cut a finger at a different opening at the time of forward and backward movement of the finger cutting cutter,
A finger cutting cutter is attached to an arm formed to be rotatable in a plane including a fixed axis of the wood and a moving axis of the cutter, and when the finger cutting cutter moves forward and backward to cut the wood opening of each piece of wood. Alternatively, the finger cutting cutter can be formed so as to enter from the obtuse angle side with respect to the inclined surface of each edge. The reason why the finger cutting cutter is made to enter from the obtuse angle side of the sloping edge is to prevent the processing surface of the wood from being crushed during the cutting.

The arm is mounted on a support so that the fingers to be cut are shifted by half a pitch when the finger cutting cutter is advanced and retracted, and the support is mounted on the support with the fixed shaft of the wood. A method of providing a slide surface perpendicular to a plane including the moving axis of the cutter, and moving the arm in parallel along the slide surface;
A method can be adopted in which at least one of the wood placing tables of the two wood fixing devices is translated in a direction perpendicular to the plane.

By attaching a gluing roller whose rotation axis is parallel to the rotation axis of the finger cutting cutter to the arm and whose longitudinal sectional shape is equal to the shape of the finger to be machined, the joint surface machined simultaneously with the cutting work The adhesive can be applied to the substrate, and labor for applying the adhesive manually can be saved.

Further, by moving on the same axis as the cutter moving axis and attaching two rotary saws having a rotation axis perpendicular to both the axis and the rotation axis of the finger cutting cutter, the cutting was made at a right angle. The slope finger joint material can be manufactured using the wood of the tip as it is, and the step of forming an inclined surface on the tip in advance can be omitted.

In this case, the finger cutting cutter and the two rotary saws move on the same axis, so that the inclination of the inclined surface of the tip and the inclination of the finger to be machined can be accurately matched, and Since the cutting depth of the finger along the cutting edge can be made uniform, the load of the finger cutting cutter during cutting can be stabilized, and a more accurate joint surface can be formed.

[0021] A stopper for determining the positions of the tips of the two pieces of wood is detachably attached to the tip of the wood table of the two wood fixing devices so that the axial position of each piece of wood can be easily and accurately determined. After setting the axial position of the wood, the stopper can be opened to process the wood opening. The stopper can be attached to the two rotary saws.
