Abstract
Two destacking tables and two can body forming stations are provided, the latter forming cylindrical can bodies from the metal sheets stacked on the destacking tables. These can bodies are subsequently conveyed along the feed axis to the welding station, which welds the longitudinal seam of the can bodies. The provision of two destacking tables and two can body forming stations enables these elements to operate at the cycle rate of the welding station. This permits welding to be effected with an increased cycle rate, with reliable feeding of the can bodies despite this.
Claims16
A process for forming metal sheets into can bodies and feeding the can bodies into a single can welding station, comprising the steps of:
- destacking individual metal sheets from two separate stacks of metal sheets using two destacking stations, each destacking station being associated with a respective stack;
- feeding the destacked metal sheets from the destacking stations to respective ones of two can body forming stations, each destacking station having an associated can body forming station;
- forming individual metal sheets into can bodies at the can body forming stations;
- and
- sequentially transporting the can bodies in two arcuate paths from respective can body forming stations to a single feed path for a welding station using two arcuate conveyors.
An apparatus for forming metal sheets into can bodies and feeding the can bodies into a single can welding station comprising:
- destacking stations for destacking individual metal sheets from two separate stacks of metal sheets, each destacking station being associated with a respective stack;
- can body forming stations for forming individual metal sheets into can bodies, each can body forming station being associated with a respective destacking station;
- means for feeding the destacked metal sheets from a destacking station to a respective one of two can body forming stations;
- and
- arcuate conveyors for sequentially transporting can bodies in two arcuate paths from the can body forming stations to a single feed path for a welding station.
