Abstract: A manufacturing system including a container manufacturing line for manufacturing a container, and a filling line for filling the container with a filler is provided. The container manufacturing line is coupled to the filling line, and the container manufactured in the container manufacturing line is supplied to the filling line. The container manufacturing line may include a first speed control unit for controlling a manufacturing line speed depending on a filling line speed of the filling line. The first speed control unit may change the manufacturing line speed of the container manufacturing line depending on a change in a number of containers in a predetermined process of the filling line.

Abstract: It is configured such that, for performing variable engravement for each formed object on a coil material to be fed to a press machine for molding a part of a can, a formed object with an engravement can be molded at a high productivity. A laser engraving device is a device for performing laser engraving on a coil material to be fed to a press machine for molding a part of a can, and includes a feeding mechanism for deeding a coil material at a predetermined speed, a laser head for irradiating the coil material fed at the predetermined speed with a laser beam, and performing engravement for each formed object, and a data communication unit for switching engraving data of the laser head. The data communication unit collectively switches a plurality of engraving data to be subjected to engravement on a plurality of formed objects, and the laser head continuously performs engravement of the plurality of engraving data on predetermined positions of the coil material.
