Claims (1)

[Claims for Utility Model Registration] A support 14 of a band saw frame 10 is erected at one corner of a material placement table 11 that is rectangular in plan view, and the support 14 points toward the center of the table 11. A driven pulley 15 is rotatably mounted on a shaft in a driven pulley storage chamber 13 which is supported and projecting diagonally, and is rotatably driven by a motor 18 into a drive unit storage chamber 12 corresponding to the driven pulley storage chamber 13. In the band saw machine for frozen foods, the driving pulley 16 is pivotally supported, and an endless band saw B is wound so as to circulate between the upper and lower sides of the driven pulley 15 and the driving pulley 16. In order for the saw teeth 17 of B to correctly face the material feeding direction M, a part of the band saw B as it advances downward P is twisted up from the band saw hanging surface of both pulleys 15 and 16 at an angle of about 45 degrees. In order to change the direction by a certain angle θ, a band saw B is installed inside the driven pulley storage chamber 13.
Upper and lower two stages of idle rollers 29 and 31 facing the traveling path S-S toward the lower P from the outside, and both rollers 2 that also face the traveling path S-S from the inside
9, 31 and the middle idling roller 30 that maintains a constant height interval H1, H2, a total of three rollers are installed in an array. The mutual gap W1 with the circumferential surface is similarly set wider than the mutual gap W2 between the circumferential surface of the middle stage idle roller 30 and the circumferential surface of the lower stage idle roller 31, and first, both the upper stage and the middle stage idle. Roller 29, 30
While holding the bandsaw B by the
6 from the bandsaw hanging rack surface by twisting it by a certain intermediate angle θ1, and while continuing to sandwich the band saw B between the middle and lower rollers 30 and 31, cut the band saw B from the band saw hanging rack surface to the target. The final angle θ2
1. An automatic band saw direction changing device for a band saw machine for frozen food, characterized in that the band saw direction is automatically changed stepwise as if twisting up to .
