Mini Vertical Buffer Conveyor
Mini Vertical Buffer Conveyor for PCB – Vanstron
This vertical buffer is designed to have the function as LIFO, Loader, Unloader, Pass through, NG OK functions, which can be located between SMT machines to improve the working efficiency by buffering.
The Mini buffer consists of a vertical buffer and a 500mm conveyor, and is placed in the line to balance board flow in LIFO buffer mode, act as a line splitter in Loader or Unloader mode, or good/bad board separator in Triggered mode. Width adjustment, work mode, and other functions, are all accessed from the hand control unit, which makes the unit easily managed.
Application
Mini Vertical Buffer Conveyor In LIFO mode, boards are received from a preceding machine and are buffered when the subsequent machine is occupied. A board is lowered from the buffer and transported to the subsequent machine as soon as it becomes ready.
In Loader mode, a maximum of 10 boards can be manually loaded in the buffer to provide the subsequent machine with a constant board flow In Unloader mode, a maximum of 10 boards received from the preceding machine, are stored in the buffer for manual removal. In Triggered mode, boards signaled as bad (NG) from the preceding machine are stored in the buffer for manual removal, while good boards continue down the line to the subsequent machine.
