Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timber processing system for performing predetermined processing on timber so that the timber can be assembled as a building, and more particularly to a climbing beam processing and a joint processing. The present invention relates to a processing system for architectural timber that can cope with the above.

[0002]

2. Description of the Related Art A conventional construction wood processing system processes wood into a state in which it can be assembled as a building. The prescribed processing was performed.
According to such a system, wood can be trimmed to a required length with a tool that can move in the vertical and horizontal directions with respect to the wood flowing on the conveying means, or the tip of the wood can be formed into a shape required when assembled as a building. It can perform machining or cutting.

In addition, the code | symbol T in a figure has shown the roof of a building.

[0004] However, the above-mentioned conventional processing system for architectural timber corresponds only to the processing of the cut edge of ordinary wood, that is, the cut edge that forms a plane perpendicular to the longitudinal direction of the timber. However, it does not correspond to the processing of wood that requires processing of a surface inclined at a predetermined angle with respect to the longitudinal direction of the wood.

[0005] Accordingly, the climbing beam and the joint palm are taken out of the processing line and processed by a single machine, or the kiguchi is cut by a separate dedicated processing line having a cutting means provided at a predetermined angle. Therefore, the workability deteriorates, and it is not possible to collectively input data including climbing beam processing and joint beam processing, so that there is a problem that data input errors are easily induced.

[0006] In recent years, a method of assembling a building with metal fittings (a method of connecting wood pieces with metal fittings) has been adopted in view of the strength of the building. Can not be processed, and only the bracket mounting part is processed by a single machine,
Alternatively, it is necessary to perform processing using a separate dedicated line, and the workability has deteriorated.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and a first object of the present invention is to process a kimono inclined at a predetermined angle with respect to the longitudinal direction of wood, such as climbing beam processing or joint palm processing.
And a processing system for architectural wood capable of improving both workability and work process by performing both processes in a collective system. A second object is to provide a processing system for architectural wood that is compatible with wood to which an assembly method using metal fittings is applied.

f, 23'a to 23'f are fixed to a rotating plate 24 or a rotating plate 24 'rotatable around C1 or C2. As shown, the rotating plate 24 and the rotating plate 24 'are disposed at right and left positions with respect to the wood W on the processing line, respectively, and are configured so that the blades can be processed by approaching the cutting tool from both left and right directions of the wood W. ing.

With this configuration, each rotating plate 2
By rotating each of 4 and 24 ', a cutting tool suitable for the processing data sent from the data creating section 1 can be brought closest to the wood W to be processed, and side processing can be performed from both left and right sides.

The wood W having been processed by the side processing section 6 is conveyed to the upper and lower processing sections 7 by a chuck hand, and drilling is required based on the processing data sent by the data creating section 1 ( For example, it is applied to the pin hole 18 formation location in FIG. 10). When it is not necessary to form a vertically extending hole in the wood W on the processing line, the wood W is carried out of the series of systems through the upper and lower surface processing portions 7.

According to the building wood processing system,
Wood with a skew angled at a predetermined angle and wood without skew (having a skew perpendicular to the longitudinal direction of the timber) can be mixed and flown on the processing line, eliminating the need to separate them. Therefore, workability can be improved. Further, since a shape for attaching a fitting (a pipe or a fitting) required when wood is assembled as a building can be processed, it is possible to collectively cope with a method of assembling with the fitting.

Although the present embodiment has been described above, the present invention is not limited to this. For example, the inclined processing portion is for cutting wood in a direction inclined at a predetermined angle with respect to the longitudinal direction thereof. If so, another device other than the ATC device may be used. Further, the processing data created by the data creation unit 1 may be directly transmitted from the data creation unit 1 to each processing unit online, or the processing data may be recorded on an information transmission medium such as a floppy disk once. The recording may be transmitted to each processing unit.
