Pouch roll replacement system
A pouch roll replacement system comprises a transport part, a replacement chucking part, an unwinder chucking part, a measuring part, and a control part. The transport part transports a replacement pouch roll and is capable of adjusting the central axis height of the replacement pouch roll The replacement chucking part is provided to chuck the replacement pouch roll transported through the transport part and has a predetermined chucking height The unwinder chucking part accommodates a traveling pouch roll and the measuring part measures the distance to the replacement pouch roll seated on the transport part before transporting the replacement pouch roll to the replacement chucking part. The control part controls the transport part so that the central axis height of the replacement pouch roll seated on the transport part is adjusted based on the measurement information of the measuring part and the chucking height of the replacement chucking part.
