A system for performing sequential operations on a can body, such as necking the open end of the can body, in which two or more machines, such as die necking machines are, are coupled by a transfer module. The transfer module comprises a multi-pocket wheel that receives can bodies from a multi-pocket discharge wheel of the first necking machine and discharges them to a multi-pocket input wheel of the second die necking machine. The drive motor of one of the necking machines is eliminated, while the drive motor on the other machine is enlarged. A gear on the transfer module couples the gear trains on the first and second necking machines into a common gear train. Thus, the transfer module gear train transfers power from the necking machine having the enlarged drive motor to the necking machine for which the drive motor was eliminated. This enables a single drive motor to entire drive train for both machines.
A necking system for successively reducing the diameter of the end of a can in a plurality of discrete steps, comprising:
A method for directly coupling first and second necking machines for successively reducing the diameter of the end of a can in a plurality of discrete operations, said first necking machine comprising (i) at least a first necking module for partially reducing said diameter of said can end, (ii) a discharge wheel for discharging said partially necked can, and (iii) a first Rear train, said first gear train comprising a first gear driving said discharge wheel, said second necking machine comprising (i) an input feed wheel for receiving said partially necked can, (ii) at least a second necking module for further reducing said diameter of said can end, and (iii) a second gear train, said second gear train comprising a second gear driving said input feed wheel, wherein said first and second necking machines each have a motor, said motor of said first necking machine driving said first gear train, said motor of said second necking machine driving said second gear train, said coupling method comprising the steps of:
A method for directly coupling first and second machines for successively performing operations on a can in a plurality of discrete operations,. said first machine comprising (i) at least a first module for performing at least a first operation on said can so as to produce a partially operated upon can, (ii) a discharge wheel for discharging said partially operated upon can, and (iii) a first gear train, said first gear train comprising a first gear driving said discharge wheel, said second machine comprising (i) an input feed wheel for receiving said partially operated upon can, (ii) at least a second module for performing at least a second operation on said can, and (iii) a second gear train, said second gear train comprising a second gear driving said input feed wheel, wherein said first and second machines each have a motor, said motor of said first machine driving said first gear train, said motor of said second machine driving said second gear train, said coupling method comprising the steps of:
A method for directly coupling a first necking module to a necking machine, said necking machine comprising (i) at least a second necking module, said necking module having means for partially reducing the diameter of a can end, (ii) a discharge wheel for discharging said partially necked can, (iii) a first gear train. said first gear train comprising a first gear driving said discharge wheel, and (iv) a motor, said motor driving said first gear train, said first necking module comprising (i) an input feed wheel for receiving said partially necked can, (ii) means for further reducing said diameter of said can end, and (iii) a second gear driving said input feed wheel, said coupling method comprising the steps of:
