D′と垂直なＦ−F′線と一致する。 The operation explanatory diagram in Fig. 6a shows the state before the upper saw wheel 4 of the band saw machine tensions the band saw a, and the operation explanatory diagram in Fig. 1a and 2
The upper saw wheel 4 is located at the lower position as shown in FIGS. When the second pressure cylinder 12 is inserted and the second pressure cylinder 12 is operated, the sliding frame 15 moves along the sliding line of the bracket 9 along the line E-E' parallel to the saw line D-D'. The movable rod 8 is slid so that the band saw a is aligned with the line F-F' which is orthogonal to the saw line D-D'. That is, the sliding frame 1
Stopper (stop valve) so that 5 remains stationary.
22 is installed, the sliding frame 15 is guided by the sliding rod 8 of the bracket 9 through the knuckle 13 and the pin 14, and moves up along the E-E' line parallel to the saw line D-D'. 1b and 2b, it comes to rest against the stopper 22 as shown in FIGS. Therefore,
The band saw a on the protection plate 18 of the saw mounting base 19 has a saw line D-
It coincides with the F-F' line perpendicular to D'.

D′と平行なＥ−E′線上で静止する。 Then, when the first pressure cylinder 26 is operated as shown by the arrow in FIG. 6c, the setting box 23 slides on the guide rod 28, as mentioned earlier.
And when it moves from the saw line D-D' and comes to the line E-E', it stops, and the setting box 23 slides on the guide rod 28 via the bracket 25 and the connecting rod 24, and moves to the saw line D-
It comes to rest on the E-E' line parallel to D'.

上に存在する。すなわち、第２図ｂに示すように
帯鋸ａの頭上に前記揺動アーム３５，３６の電磁
石３７，３８が位置するものである。 Therefore, since the swing arms 35 and 36, which are provided symmetrically to the C-C' line, are also built into the setting box 23, they move together with the setting box 23 and are located on the E-E' line. . That is, as shown in FIG. 2b, the electromagnets 37 and 38 of the swing arms 35 and 36 are positioned above the head of the band saw a.
ここで、第３図ｂおよび第６図ｄに示すように

静止する。 Here, when the pressure cylinders 47, 49 are operated as shown in FIG. 3b and FIG. Since the swinging arms 35 and 36 move and descend to the protection plate 18 of the saw mounting base 19, the swinging arms 35 and 3
6 descends using the pins 43 and 44 as fulcrums, and the electromagnet 3
7 and 38 come into pressure contact with the bandsaw a on the protection plate 18 and come to rest.

静止する。 Then, when the coils of the electromagnets 37, 38 are energized, an attractive force is generated in the electromagnets 37, 38, so when the electromagnets 37, 38 attract the bandsaw a and operate the pressure cylinders 47, 49 again, the third
As shown in Figure a and Figure 6e, the swinging arm 3
The electromagnets 37 and 38 of 5 and 36 leave the protection plate 18 while adsorbing the bandsaw a, move up along the line E-E', and remain stationary in the state before operating the pressure cylinders 47 and 49.

車４に掛る。 Subsequently, when the first pressure cylinder 26 is operated again, the setting box 23 is moved to E- as shown by the arrow in the figure while holding the band saw a, as shown in FIG. 6f.
Move from line E' to saw line D-D'. That is, since the band saw a moves onto the upper saw wheel 4 together with the electromagnets 37 and 38 of the swing arms 35 and 36, after lowering the swing arms and the electromagnets 37 and 38 as shown in FIG. 6g, When the coils of the electromagnets 37 and 38 are de-energized, the adsorption force is lost, so the bandsaw a moves to the electromagnet 3.
7, 38 and hangs on the upper saw wheel 4 as shown in FIG. 6h.
この後、上部鋸車４を上昇させて帯鋸ａを重錘
Ｗの質量を増して緊張させることで製材が可能に
なる。 Thereafter, the upper saw wheel 4 is raised and the band saw a is tensioned by increasing the mass of the weight W, thereby making it possible to saw lumber.

る。 The sawing operation of the bandsaw machine of this invention follows the above-mentioned process, but the sawing operation is the reverse operation. In other words, band saw a is F-
The first pressure cylinder 26 is activated after it coincides with line F', and when the setting box 23 is on line E-E', the pressure cylinders 47 and 49 are activated. is configured to operate again, so by simply controlling the current flowing through the coils of the electromagnets 37 and 38 of the swinging arms 35 and 36, the bandsaw a moves from the E-E' line to the sawing line D-D'. After that, it is set between the upper saw wheel 4 and the lower saw wheel 17.

As described above, this invention provides a setting box that engages a swinging arm having an electromagnet on the sawing line between the upper saw wheel and the lower saw wheel, and connects the connecting rod to which the setting box is attached at right angles to the sawing line. A band saw hung on a saw mount that can be moved in the vertical direction by the second pressure cylinder is attracted to the electromagnet from the saw mount to the upper and lower saw wheels. Since the band saw hooked or hung on the saw wheel can be removed by moving the setting box, it is possible to hang the band saw between the upper saw wheel and the lower saw wheel, and to remove the band saw from both saw wheels without the need for manpower. Since it can be done safely and quickly, it has the advantage of not damaging the saw wheel.
