Claims

[Scope of utility model registration request]

(1) In a roll feed in which the material is fed by the rotation of the rolls while being sandwiched between a pair of rolls, there is a first cylinder in which the piston moves reciprocatingly in synchronization with the vertical movement of the slide, and the reciprocating movement of the piston in this first cylinder. a second cylinder whose piston is reciprocated in accordance with the movement; and means operated by the reciprocating movement of the piston of the second cylinder to separate one of the rolls from the other roll. A roll feed release device characterized by:

(2) Utility model registration Claim 1, wherein each of the first cylinder and the second cylinder has a structure in which incompressible fluid chambers are provided on both sides of a piston, and each incompressible fluid in the first cylinder is A roll feed release device characterized in that the chamber and each compressed fluid chamber of the second cylinder are connected to each other by piping.

(3) Utility Model Registration Scope of Claim 1 In claim 1, the first cylinder has a structure in which a non-compressible fluid chamber is provided on one side of the piston, and the non-compressible fluid chamber and the piston of the second cylinder 1. A roll feed release device characterized in that one partitioned chamber is connected to the other chamber by piping, and a constant pressure is applied to the other chamber of the second cylinder.

(4) Utility model registration Claims In any one of claims 1 to 3, the spacing means rotatably supports one of the rolls at one end and rotatably supports substantially the center thereof. It is characterized by comprising an arm that is rotationally displaced as the piston of the second shilling moves forward and backward, and a spring that constantly biases the other end of this arm toward the piston of the second shilling. Roll feed release device.

(5) Utility model registration Claims In any one of claims 1 to 3, the separating means includes a cylinder that moves one of the rollers toward and away from the other roller;
A release device under a roll feed, comprising a fluid source and a switching valve that is switched in accordance with the movement of the piston of the second cylinder to supply fluid pressure from the fluid source to the cylinder.
