[0001] The present invention relates to a traveling planer.

[0002]

2. Description of the Related Art When processing large lumber such as pillars and beams, a workpiece is placed on a surface plate and cut by a planer held on a traveling frame reciprocating along the surface plate. A so-called traveling planer for processing is known. As described above, in the case where the workpiece is fixed on the surface plate and the planer is moved to perform planer shaving, a large workpiece is not moved as compared with the processing using a normal fixed planer. Therefore, workability is good and processing can be performed more accurately. In addition, since the cutting process is performed on the workpiece fixed on the surface plate, uniform horizontality without twisting of the processing surface is realized, and the squareness and thickness become accurate. Has great advantages.

On the other hand, in the construction of shrines, temples and temples, various curved processing of large timber is required. For example, the beam at the front of the shrine has a cross section of 300 mm in length and width of 6000 to 80 mm.
2. Description of the Related Art Conventionally, cloud processing with a length of 00 mm has been cut by a skilled worker. Such a curve is a complicated curve containing various curve elements, and requires a high level of programming and a lot of time if appropriate equipment and current electronic control technology are used. It is not easy to get closer to a handwritten curve. However, in many cases, such a curve processing is only one or two special and the same, and therefore, it is not cost-effective to use expensive electronic devices and create a program. Also, there are not many electronic engineers and programmers for this purpose in this kind of industry.

On the other hand, in the field of timber processing generally including buildings such as shrines and temples, when large-sized timber is processed into a specific curve, a model shape of the same size (generally called a template) is previously formed by a thin plate material such as a plywood plate. ) Is created to perform actual matching or shape correction. Therefore, if processing can be performed using this template as it is, it is possible to work economically and efficiently without creating any special program.

As shown in the figure, the lower limit position of the planer board 30 by the elevating device 40 is set so as to be sequentially lower. Then, the cutting can be performed by dividing the traveling planer into a plurality of runs. That is, in FIG. 9, the planer board 30 first travels at the level Ll, rises at the front end, returns to the original position, and then advances at the level L2. The cutting process is performed by repeatedly traveling the levels L3 and L4 sequentially.

FIG. 10 shows each of the cutting steps in the order of the drawings. In (10A) of FIG. 10, as described above, the lower limit position of the planer board is set to the level of L1, so the portion Cl of the workpiece Ml that is above this L1 level is cut. . Next, as shown in FIG. 10B, the portion C2 above the lower limit position L2 level of the next planing board set for the workpiece M2 processed in the step (10A) is cut. You. Thereafter, the portion C3 of the workpiece M3 is sequentially cut at the next lower limit position L3 of the planer board, and the portion C4 of the workpiece M4 is sequentially cut at the lower limit position L4 of the next planer board. A copy N is manufactured.

The maximum thickness of the workpiece which can be cut at a time by the planer block of the planer board of the embodiment is about 7 m.
m, it is set so as to descend sequentially based on this thickness. In the embodiment, if the lowermost lower limit position is set in advance, the lower limit positions are sequentially set downward by the reference thickness, and processing is automatically repeated.
