Article processing system
First Claim
1. 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.

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.
