Insertion Mount machines with internal BHS can work with external devices
to automate board flow and improve throughput. This section describes how
magazine unloaders and loaders work with the IM machine Board Handling
System.
Elevator/conveyor operation is controlled by the Advanced Magazine Loader
or Unloader.
• This device consists of an input conveyor on the bottom section, an
elevator, and an output conveyor on top. The unloader is located
upline of the insertion machine. It unloads a board from a magazine
and supplies it to the insertion machine to be processed.

A magazine containing boards to be processed by the insertion
machine enters the elevator from the lower conveyor. As each
board is transferred from the topmost slot of the magazine to the
insertion machine, the elevator lifts up the magazine a programmed
distance so the next board in the magazine is in position to be
supplied to the insertion machine. When the magazine is empty, it
moves out of the elevator and onto the upper conveyor.

Magazine Loader

• This device consists of an input conveyor on the top section, an

elevator, and an output conveyor on the bottom. The loader is

located downline of the insertion machine. It receives a processed

board from the insertion machine and loads it into a magazine.

An empty magazine enters the elevator from the upper conveyor.

As each board from the insertion machine is transferred into the

bottom usable slot of the magazine, the elevator moves down the

magazine a programmed distance so the next usable slot is in

position to receive the next board. This programmable distance

allows clearance for tall components on the processed board. When

the magazine is full, it moves out of the elevator and onto the lower

conveyor.
