Claims

[Scope of utility model registration request]

A frame 11 , a main roll 14 rotatably supported at both ends by the frame 11 , a support shaft 23 supported by the frame 11 with its axis parallel to the axis of the main roll 14 , and the support shaft 23 and a pair of sub roll arms 24, 24 rotatably supported at both ends thereof, and both ends of the main roll arms 24, 24 are rotatably supported by the pair of sub roll arms 24, 24, respectively.
Sub-roll 2 that intermittently conveys the plate materials in cooperation with
6, a set spring 28 that urges the sub roll 26 toward the main roll 14 side, and a set spring 28 that is rotatably provided on the frame 11 and is driven to rotate when the main roll 14 and the sub roll 26 stop conveying the plate material. , the sub-roll arms 24, 24 are rotated about the support shaft 23, and the sub-roll 26 is rotated around the set spring 28.
In the roll feed including a cam shaft 30 that moves in a direction away from the main roll 14 against the urging force of An auxiliary spring 31 is provided to bias the shaft 30 toward the shaft 30, and the support pieces 18, 18 rotatably support both ends of the support shaft 23 on the frame 11 in a direction in which the sub roll 26 approaches and moves away from the main roll 14. Set up so that it can be moved freely,
Fixing members 20, 20 are provided between the support pieces 18, 18 and the frame 11 to prevent and fix the support pieces 18, 18 from moving toward and away from each other. The axis of the fixed shaft 21 is parallel to the support shaft 23, and has both ends that penetrate through the fixing shaft 18 and are threaded into the reverse threaded portions screwed onto each of the fixed members 20, 20. A mantle member 39 that is loosely fitted is provided, and a handle 22 that can rotate the fixed shaft 21 in forward and reverse directions is provided at one protruding end of the fixed shaft 21 protruding from the one fixed member 20. A roll feed characterized in that the support pieces 18, 18 are brought into contact with and separated from each end of the mantle member 39 as it rotates.
