Abstract
A star wheel H of a blow molding machine 13 constituting a blow molding line 2 as a master machine driven by a motor M is provided with an encoder E for generating a pulse depending on rotation of the star wheel H, and a filling line 3 as a slave machine driven by first to fifth servomotors SM1 to SM5 is controlled by second control means 5 based on a pulse from the encoder E. In the event of an abnormality in the blow molding line 2, the second control means 5 controls the filling line 3 based on a pulse from a pulse generator 5a instead of a pulse from an encoder E, and thus performs processing of a vessel retained by the filling line 3. Even in the event of an abnormality in the master machine, the slave machine can be continuously operated.
Claims4
An article processing system, comprising a master machine having a revolving body, a slave machine operating in synchronization with the master machine, an encoder for generating a pulse depending on rotation of the revolving body of the master machine, and control means for receiving a pulse from the encoder and synchronizing the slave machine with the master machine;
- wherein the control means is provided with a pulse generator for generating a predetermined pulse;
- wherein the control means controls the slave machine based on a pulse generated by the encoder during normal operating of the master machine;
- and
- wherein in the event of an abnormality in the master machine, the control means controls the slave machine with a pulse generated by the pulse generator.
