Claims

[Claims for Utility Model Registration] (1) A belt reversing device for reversing the belt 180 degrees after the head pulley or the drive unit, which includes a carrier roller stand mechanism for holding the carrier side belt on the upper part of the stand. A belt reversing device having a structure in which a belt holding roller mechanism is disposed at a lower part of the belt so as to hold the return side belt at a height lower than the belt width at the reversing part. (2) In the belt holding roller mechanism, a roller support bracket whose position can be adjusted in a direction perpendicular to the bracket is installed on the bracket attached to the bottom of the stand so that the position can be adjusted, and a return side is attached to the roller support bracket. Claim (1) characterized in that a plurality of holding rollers for conveying and holding the belt are provided in an annular arrangement.
Belt reversal device as described. (3) In the belt holding roller mechanism, a roller support bracket whose position can be adjusted in a direction perpendicular to the bracket is installed on the bracket attached to the bottom of the stand so that the position can be adjusted, and a return side is attached to the roller support bracket. Claim (1) characterized in that the plurality of holding rollers for conveying and holding the belt are arranged in an elliptical arrangement.
Belt reversal device as described. (4) In the belt holding roller mechanism, a roller support bracket whose position can be adjusted in a direction perpendicular to the bracket is installed on the bracket attached to the bottom of the stand so that the position can be adjusted, and a return side is attached to the roller support bracket. A claim characterized in that a plurality of holding rollers for conveying and holding the belt are arranged in a horizontal U-shape.
The belt reversing device described in (1).
