CONFIGURATION
:- The
system will have
following
features :-
* It will have
number of
carriers
suspended
closely on a
pair of
heavy duty
endless chains
interconnected
through a common
shaft and driven
by reversing
electric motor
through a
suitable
reduction gear
box. Each
carrier will
accommodate
number of steel
/ plastic bins.
It will be
possible to
enter the codes
of different
components and
their address
and the quantity
when the storage
system is fed
and
to bring the
particular bin
for unloading
when the
component
number is fed
through a
keyboard.

A Computer or
microprocessor would be
controlling this
operation. A bulb will
get illuminated for the
items called for. The
drive part of the system
consists of a motor,
gear box, chains and
sprockets, brake, hand
cranking etc will be on
the right hand side and
will be fully accessible
to the maintenance
people without providing
access to the bins. It
will be possible to do
the hand cranking in
case of power failure of
any other defect in the
system for taking the
material out. The other
side will have the
controller, Sensors and
relays fuses etc.
The long shelves will be
sturdy enough to take
the specified load of
the components and the
bins. The carriers will
be designed with the
provision for partition
plates for creating
internal bins. Carriers
will have front
retainers of 150 mm.
The system will have
single window wherein
material shall go inside
and come outside from
the single window. The
window will be on the
front side.
CONTROLS / KEYBOARD
:- A membrane type
keyboard will be mounted
on the carousel which
will be used for carrier
no bin/no calling.
Manual UP / DN operation
of the carousel will be
through 2 push buttons
switches provides on the
control panel.
Interfacing with
computer will be
throughRS232 port
provided in the control
panel. The display unit
will have 7 segment type
6 digits display in 1
row only for computer
mode the display unit
will be the computer
monitor itself. The
software will provide a
facility to the operator
to create a database for
the components stored in
the carousel. Database
will have data for each
component like component
number, description,
carrier number, bin
number, present qty.,
max. level, min. level.
The present qty will be
updated as per the
transacted qty after the
transaction. A stock
report printing facility
will be provided from
the software.
SYSTEM OPERATION :
The carousel operation
will be by 4 types
:Component to calling
operation. List mode
operation./Carrier no
calling operation/
Manual up / down push
button operation.
Component no calling
operation : Operator can
select this made of
operation through
software proved by us.
In this mode of
operation, operator will
enter the called
component no Carousel
will rotate and the
called carrier no .will
be made available at the
operating window. While
carousel is rotating
details of called
components will be
displayed in the
monitor. This will
include the present
stock level, min. level
and max. level along
with the present carrier
no. called carrier no.
and bin no. Once called
carrier is at operator
window, operator will
enter the type of
transaction (issue
/receipt) and the
quantity to the
transacted. Operator
will complete the
transaction and the
software will be ready
for the next operation.
List mode : Software
will provide facility to
prepare a list of
components to be
transacted from
carousel. Operator will
select the list
operation mode after the
list is prepared. Once
the operator selects
List mode monitor will
show details of first
components to be
transacted. The details
will be as described
earlier. The computer
will ensure that the
minimum carousel
rotation will be done
while taking up the
