Roll accommodation unit, processing apparatus, and roll setting method

Abstract

A roll accommodation unit includes: a roll support shaft; a pair of side walls; and a pair of roll bearings that are attached to the pair of side walls, recessed portions are formed at upper ends of the pair of side walls, the pair of rolling bearings are attached to the side walls at positions corresponding to bottoms of the recessed portions such that the rolling bearings project upward beyond inclined surfaces of the recessed portions, the roll support shaft includes a support shaft main body, and a pair of small-diameter portions that are provided at both ends of the support shaft main body, and the roll support shaft is supported with the small-diameter portions abutting on outer circumferential surfaces of the pairs of rolling bearings in a state in which the support shaft main body is located at an interval from the recessed portions.

What is claimed is: 
     
         1 . A roll setting method of a processing apparatus that includes a roll accommodation unit that accommodates a roll of a continuous sheet such that the roll is rotatable about a horizontal axis and a main body that pulls out the continuous sheet from the roll accommodation unit and performs processing on the continuous sheet, the roll setting method comprising:
 a separation step of separating the roll accommodation unit attached to the main body from the main body and causing the roll accommodation unit to move;   a setting step of setting the roll in the roll accommodation unit separated from the main body in the separation step; and   an attachment step of attaching the roll accommodation unit with the roll set in the setting step to the main body.   
     
     
         2 . The roll setting method according to  claim 1 , wherein in the setting step, the roll is set by either a first setting method in which an operator sets the roll in the roll accommodation unit or a second setting method in which a lift that is able to move the roll upward and downward sets the roll in the roll accommodation unit. 
     
     
         3 . The roll setting method according to  claim 2 , wherein in the second setting method, an arm of the lift moves upward up to a position that is higher than the roll accommodation unit, the lift approaches the roll accommodation unit, and the arm of the lift moves downward to place the roll on the roll accommodation unit.
