Function
Raises by just over two inches to secure a carrier; lowers to allow for the
retrieval of a carrier. It is controlled by an actuated motor that is attached to
the bottom edge of the security door with a small bolted plate. Movement is
achieved by rotating a threaded rod that is connected to the plate.
While the door is being closed, if it encounters any interference (such as a
user's hand or carrier in its path), it automatically opens again and remains
open until a new transaction is initiated.
The security door slides up and down with the help of four stationary ball-
bearings that hold the door in line at the upper and lower edges of the rods at
the outer edges of the door.
Controls movement of the security door. Includes a motor attached to a
motor mount, which includes a rod with a plate that is bolted to the bottom
of the security door. When engaged, the motor raises or lowers the plate on
the rod to control the up and down movements of the security door.
The slide-plate cover both contains air within the slide plate assembly and
protects the slide plate from dust and debris. The slide plate cover is partially
transparent in this drawing to show the slide plate assembly.
The gear and arm (shown more clearly in the top assembly views) move the
slide plate to open and close it as necessary for carriers to enter and exit the
station. The arm swings in a 90-degree arc to move the slide plate back and
forth.
The slide-plate is controlled by two magnetic sensors and a gear motor that
moves a mechanical arm in a 90-degree arc to open and close the slide plate.
Control of the rotary valve is the same with two additional magnetic sensors
and a gear motor that controls the opening and closing of the rotary air valve.
Magnetic sensors track the open and closed positions of the rotary air valve.
Provides power to the slide plate.
Connects the existing pipe to the slide plate and the complete turnstile
assembly. The tube is made of flexible rubber that is bolted at the ends with
metal brackets, to which the brake actuator is attached.
Located above the slide plate on the rubber collar beneath the brake assembly,
the tube sensor detects carriers as they enter and exit the station. It also
determines timing for turning on the blower to provide air flow.
When this sensor fails to detect a carrier, a "missed sighting" alarm is posted
to the SCC.
The turnstile mechanism is a rotating cylinder that includes five separate
compartments for holding carriers being dispatched from and received into
the station. The turnstile moves to the left or right to accept and release carri-
ers in the front position and prepare carriers for dispatch at the back position
that aligns with the station pipe.
