Reference numeral 1 is a lumbering apparatus to which the present invention is applied, which is configured by combining a band saw machine 2 and a material feeding apparatus 3. First, the band saw machine 2 comprises a main body 10 and a support base 11 for supporting the main body 10. The feature of the present invention is that the main body 10 is constructed so that it can move sufficiently on the support base 11. There is a point. First, the machine 10 is basically applicable to a conventional band saw machine configuration, in which a lower wheel 14 and an upper wheel 15 are vertically arranged with respect to a frame 13, and a band saw blade 16 is provided between them. It has a basic structure that is formed by suspending. First, the lower wheel 14 has a lower bearing 18 below the frame 13.
Is attached to one end of a drive shaft 19 which is supported against. A pulley 20 is attached to the other end of the drive shaft 19, and the rotation is transmitted from a motor M mounted on the rear portion of the frame 13 via a belt 21. On the other hand, the upper wheel 15 is attached to one end of an upper wheel shaft 24 supported by an upper bearing 23 which is attached above the frame 13 so as to be vertically slidable. And the upper bearing 23 is an airbag 25
Which is buffered by the airbag,
The lower part of 25 is supported by a supporting part 26 from which a part of the frame 13 projects. In this embodiment, the lower wheel 14 and the upper wheel 15 are both cantilever types, and the band saw blade 16
When removing from the lower wheel 14 and the upper wheel 15, the upper wheel 15 can be replaced without pulling down the upper wheel 15, so the upper bearing 23 has a structure in which the airbag 25 directly supports the frame 13 side. However, like the conventional method, the band saw blade is supported on both sides and the frame 13 and the upper bearing are
The present invention can be applied even to a device of a type in which a ball is interposed between the device and 23. And such a machine 10
Is configured to be able to retreat with respect to the ground L on the support base 11, and the machine 10 is installed on the support base 11 extending sufficiently outward in the direction perpendicular to the ground L. That is, the base receiving portion 28 is formed in a slightly depressed shape on the machine 10 side, the base pressing plates 29 are further provided at both ends thereof, and the bearing rails 30 of the support base 11 are fitted into the space formed by this. In this way, a slidable fitting structure of the both is formed. And the ground L in the support base 11
As an example, a shifter 31 to which a hydraulic cylinder is applied is provided between the end portion on the opposite side to the main unit 10. Of course, it is needless to say that the shifter 31 can be applied to any member that can be moved in a predetermined manner such as a screw shaft or a chain appropriately driven by a motor or the like without being limited to the hydraulic cylinder. Further, as an example of the material feeding device 3, a device mainly including a material feeding wheel 33 is applied to the band saw machine 2. This is a wheel 35 provided below the material feeding frame 34.
Is rolling on the rail 36 and moves, and above the feeding vehicle frame 34, there is provided a scraping device 37 which supports the material A and takes an appropriate step. Of course, the material feeding device 3 is not limited to such a material feeding vehicle type, but may be an appropriate combination such as a roller type, a slat conveyor type, or a flat table and a spike roller.

製材工場の自動化がより図り得る。The lumbering apparatus 1 according to the present invention has the specific mechanism as described above and is used as follows. First, as an example, when the band saw blades 16 that can be used together are suspended from the two band saw blades 2, one of the band saw blades 2 is sufficiently retracted from the grinding path L, The sawing operation is performed by one of the band sawing machines 2A (hereinafter, in the case of distinguishing the band sawing machines, the band sawing machine on the cutting start side is shown as 2A and the rear side thereof is shown as 2B). Continuing such work, when the band saw blade 16 reaches the time of replacement, the band saw machine 2B, which has been waiting in the rear until now before the material A starts to grind, is moved forward to the grinding path L, while the usage limit is reached. For Kita Saw Blade 2A, move it to the rear. This is performed by appropriately contracting the hydraulic cylinder that is the shifter 31. Then, the sawing work itself is appropriately continued by the newly prepared band saw machine 2B. On the other hand, in the meantime, for the band saw machine 2A that has sufficiently withdrawn from the grinding path L, the work of replacing the band saw blade 16 is performed manually behind it. Specifically, the air in the airbag 25 is evacuated, the upper wheel 15 is pulled downward, the tension of the band saw blade 16 is released, and the band saw blade 16 is removed. Then, the usable band saw blade 16 that has already been separately prepared is further suspended, and the airbag 25 is extended again to keep the upper bearing 23 pushed up until the band saw blade 16 is given a predetermined tension. . In this state, it is waiting until the usage limit of the currently operating band saw machine 2B is reached. In addition, among the above operations, regarding the judgment of the replacement time of the band saw blade 16, in addition to the empirical visual judgment, the sensor detects the bending of the band saw blade 16 and the rough surface of the material. Determine the replacement time. When the replacement timing of the band saw blade 16 is automatically determined, the sawmill factory can be more automated.

の帯鋸盤であっても適用できることは言うまでもない。In this embodiment, as an example, a type in which two band saw machines 2 are provided has been described. For example, as shown in FIG. 5A, three band saw machines 2 are provided on one side, and two band saw machines 2 are provided. Heavy grind, or 5th
It can be applied to an appropriate type such as a double grind type in which four groups are opposed to each other as shown in FIG. Further, although the most common vertical saw band saw machine has been illustrated in the present embodiment, it goes without saying that the present invention can be applied to other types of saw band machines such as inclined saw and horizontal saw.

った。<< Effects of the Invention >> The present invention has a configuration as described above, and when performing a material cutting operation, a band saw blade 16 is always in a good cutting state.
Since the band saw machine 2 on which the band is suspended is on standby, even when the use limit of the band saw blade 16 is reached, the work can be performed by replacing the band saw machine 2 with almost no interruption of the cutting operation. Therefore, according to the conventional method, it took about 10 to 15 minutes to replace the band saw blade 16, but the processing can be continuously performed.
