Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a quadruple sawing machine that forms four rear joints at once, and in particular, the arrangement of the sawing machines has a new configuration so that the material being sawed is always accurately cut. The dimensions are set accordingly.

For example, when sawing a square lumber AI from a log-shaped lumber A, the fifth
As shown in Figure (A), the back plate A and the side plate material A are sawed out, and in this case, four rear joints are carved on the cross section of the material A. It will be done.

However, when carrying out such work, it is preferable to carve four rear joints at once, and so-called quadruple saw bandsaws are used. However, conventional devices have the following configuration, and due to this configuration, there have been technical problems as described below.

That is, when sawing such raw wood logs, in most cases, the material A is held on the material transport vehicle 2' (material transport frame) as shown in Fig. 5 (b), and Front-saw band saw machines 1'Is 1'lV and back-saw band saw machines t'II and t'■ are arranged around 2 at the center. With this kind of configuration, the material itself is held and transported by the material transport vehicle and is subjected to sawing by the band saw blades of each band saw machine, so it appears that accurate sawing is possible, but in reality it is difficult to do so. Band saw blade 12 in front sawing band saw machine 1/I% 1'■
'l.

Saw the back plate A3 with rQ', then use back sawing band saw blade 1
2'l [, 12'l[ is used to saw the inner board material A2, so in reality, the thickness of the board material is not necessarily constant due to changes in the diameter of material A, etc. This often happened.

Herein, the present inventors have particularly focused on band saw machines where the band saw blades are closely spaced opposite each other.

Each blade complements the ruler action, resulting in always accurate sawing.
Focusing on the ability to do this, we developed a device that skillfully utilizes the action of and to enable highly accurate sawing. In other words, the gist of the configuration is that a pair of sawing machines are arranged in front and behind each other, and the sawing machines form four sawn cuts on material held on a material conveying vehicle and fed. The saw blades on the saw machines are arranged next to each other to form two sawn blades on one side of the material transport wheel, while the saw blades on the other set of saw machines are arranged next to each other to form two saw blades on one side of the material transport wheel. It is characterized in that it is arranged so as to form two rear joints that are aligned to one side of the material transport vehicle.

The present invention will be specifically described below based on illustrated embodiments. Reference numeral 1 indicates a band saw, which is an example of a saw, and there are four saws having the same configuration.To distinguish between them, from the left side of the figure, tl s 111% tnI,
It is marked IIV. The band saw machine has almost a conventionally known configuration, and its main components are upper and lower tires 11 arranged vertically opposite to each other and an endless band saw blade 12 stretched between them. . The band saw blades 12 are numbered 121 to 121V to distinguish them from each other, corresponding to the four band saw machines II to 1. For such a set of band saw machines, the band saw blade 12
Material transport car 2 that holds material A between Jl and band saw blade 12■
It is intended to provide For example, this material transport vehicle 2 has a pair of left and right wheels 3 moved forward in the sawing direction onto a rail 4,
The portion extending toward the front side is configured to run by rolling wheels 7 on a single rail 6 in the center. The material conveying car 2 is provided with a brace 8 which is driven into the front and rear end surfaces of the material A in order to hold the material A. Furthermore, the construction of the material transport vehicle 2 includes a support member that can be raised and lowered in order to support the material A downwardly in its intermediate portion, and other conventional constructions of materials transport vehicles may be used as appropriate. There is no problem in applying it. It is constructed so that the sawing and splitting action positions of the band saw blades 12 I to 121V of each of the band saw machines II to 1 can be moved with respect to such a material conveying car 2, and the sawing and splitting dimensions can be set appropriately. It is.

The present invention has the configuration as described above, and operates as follows to saw and split the material A. First, the material transport vehicle 2 is pulled to the frontmost side, material A is placed there, and the material A is fixed onto the material transport vehicle 2 using a gauge 8 or the like as appropriate. At the same time, band saws II to 1 are moved as appropriate to set and fix the sawing position for the material A to be sawed. Thereafter, the material is fed in the direction of band saw machines II to 1 by means of the feed wheel 2 in accordance with the usual method. In such a case, for example, as shown in Fig. 2.4, the two sets of band saw blades 1211[, 121V] on the right side of Fig. 4 receive the sawing and splitting of the back plate A3. The part and the board material A2 to be sawn inside the part are sawn. Then, following that, back plate A3 in the left side part of material A in the figure.
The parts and the plate material A2 undergo sawing by the bandsaw blades 12I, 12I[. By the way, at this time, the left and right plates A,
is always sawn by the group of band saw blades 121112 II or the group of band saw blades 12■, 12■ that are close to each other, so the band saw blades mutually complement each other's ruler action,
This allows for accurate sawing of board materials with a constant width. In order to further produce square timber, the lumber car is returned to the starting position, the drum-shaped sawn timber A is turned over 90 degrees, and the remaining backboard portion is sawn in the same manner.

As described above, according to the present invention, in the quadruple sawing bandsaw machine equipped with a material transport wheel metal fitting, the mutual band sawing machines that are combined in front of each other in front of each other are used to perform sawing and splitting in a state where each of the band sawing machines is placed next to each other on one side of the material. Since the band saw blades perform the sawing while performing a ruler action at the 9 o'clock cutting time, it is possible to saw and split the raw wood accurately.

In this embodiment, a band saw is shown as an example of the saw, but it is of course possible to use a circular saw.
