Definitions

  • ABSTRACT A punch press includes a binmounted below adie and communicating with the latter by way of a passage which directs slugs punched from the workpiece into the bin.
  • a vacuum source is connected to a pipe leading from the bin and draws the slugs through the passage and into the bin.
  • Mounted beneath a door in the bottom of the bin is a power operated conveyor for transporting the slugs away from the bin. The door may be opened automatically during an interruption in the punching operation of the press whereby the slugs are dumped onto theconveyor after the latter is actuated to carry the slugs away from the bin.
  • a more detailed object is to provide, means in the system for detecting a faulty vacuum seal at the bin during the punching cycle and for shutting down the press to keep the press from operating without proper vacuum' in the bin.
  • a punch press having a vertically reciprocable punch adapted to coact with an underlying die to punch holes in an intervening workpiece, said press including a bin disposed below said die to collect the slugs punched from the workpiece, apassage communicating between the die and the bin, a vacuum source connected with said bin to draw the slugs through the passage and into the bin, 2. door mounted on the bin to move to an open position to enable the removal of the slugs from the bin, a conveyor disposed below the door to carry the slugs away from the bin, and means for automatically opening said door to dump the slugs onto the conveyor during an interruption in the punching operation of said press.
