Abstract
The known can seamer is improved so that replacement and adjustment of seaming rolls, a seaming chuck and a knock-out pad may be facilitated at the time of type-change work or the like in a can seamer. In the improved can seamer, after a control mode of a drive motor has been switched to a type-changing mode, if an action button is depressed, in response to signals issued from a rotational position sensor, the drive motor moves can seaming mechanisms one pitch by one pitch via a center shaft and makes them stop at predetermined positions. At the stopped position, an actuator is operated to depress the top end of a seaming roll shaft. By this operation, a gap clearance is formed between a rotary frame and a seaming lever, then seaming rolls and are mounted, also the seaming lever connected with a seaming chuck via a bracket is removed, and thereby a type-changing work can be carried out. In addition, in the type-changing work of a can seamer, it has been made possible to carry out vertical position adjustment in the fitting between a seaming lever and seaming rolls easily. Furthermore, in the type-changing work of a can seamer, it has been made possible to replace a knock-out pad by a one-touch operation.
