Abstract
An encapsulation machine utilizes servo-driven components and a control system to control the encapsulation machine. Servomotors drive the fill supply mechanism, the die rollers and the casting drums. The control system uses a programmable controller to establish relationships between the servo and non-servo-driven components of the machine and a virtual gear to facilitate and automate the operation of the encapsulation machine.
Claims39
A soft gel encapsulation machine comprising:
- a fill mechanism operable to deliver a fill material;
- at least a pair of dies;
- and
- a control device operable to control operation of said fill mechanism and said dies,
- wherein said control device is a programmable controller that uses a first movement relationship between said fill mechanism and a programmed reference, uses a second movement relationship between said dies and said programmed reference, and controls operation of said fill mechanism and said dies based on said first and second movement relationships to said programmed reference.
A capsule machine comprising:
- a fill mechanism operable to deliver a fill material;
- a first servomotor operable to mechanically independently drive said fill mechanism;
- at least first and second dies, said first die being driven by a servomotor and said second die being mechanically linked to said first die with movement of said first die causing movement of said second die;
- a second servomotor operable to mechanically independently drive said first die;
- and
- a control device operable to control operation of said first and second servomotors.
A capsule machine comprising:
- a fill mechanism operable to deliver a fill material;
- dies operable to form soft capsules from at least two sheets of material;
- a pressure device operable to apply pressure between said dies independently of operable of said fill mechanism;
- and
- a controller operable to control said dies and said pressure device,
- wherein said controller monitors a pressure between said dies during operation of said dies.
A capsule machine comprising:
- a first moveable member;
- a first servomotor operable to mechanically independently drive said first moveable member;
- and
- a control device operable to control operation of said first servomotor, said control device having a virtual gear,
- wherein said first servomotor has a first relationship with said virtual gear and said controller operates said first servomotor based on said first relationship.
A soft gel encapsulation machine comprising:
- a fill mechanism operable to deliver a fill material;
- at least a pair of dies;
- a virtual relationship between said fill mechanism and said dies;
- a control device operable to control operation of said fill mechanism and said dies based on said virtual relationship;
- and
- a serial communication ring linking said fill mechanism and said dies to said control device.
