ABSTRACT:
An unloading apparatus for a briquette press, or the like, including a horizontally movable carriage with a plurality of vacuum cups on one end thereof for seizing articles from the press. The carriage is provided with rollers that roll on stationary frame tracks to permit reciprocation of the carriage with cranks being provided between the rollers and the carriage frame so that the carriage may be lifted and lowered at the article seizing station. A drive system is provided that reciprocates the unloading carriage by chains and sprockets, and through the provision of cams for operating the cranks, the entire carriage is pivoted downwardly or upwardly while maintaining it horizontal during article seizing. A control is provided having both automatic and manual modes effecting the proper interlocking between operation of the unloading apparatus and the associated press.
The control system senses the presence of briquettes in the article seizing vacuum cups and provides signals to a counter that, through appropriate circuitry, terminates operation of the associated press if all briquettes are not present in the unloader. Also provided is a control that inhibits operation of the unloader until the press is operating and ready to be unloaded.
