In an effort to become more competitive, increase
profitability, improve quality and meet or exceed
customer's schedules, companies are turning to automated
manufacturing processes. These processes are based
on increasing production throughput, improving quality,
work consistency and increasing profitability. By
focusing on automation, companies have experienced
profit increases of 50 percent or more while shortening
lead times, improving quality and customer satisfaction.
Most
companies do not have the time, in-house expertise
or experience to evaluate the needs for the automated
processing of their products. This could have significant
drawback on the potential to increase the financial
status of the business. By focusing on this area,
huge paybacks can be obtained in many areas of manufacturing
such as, labor requirements, inventory requirements,
profitability, SPC analysis, data collection, reduction
of rejects, decrease in rework, etc.
All
businesses have the opportunity to automate many of
their processes to provide increased throughput and
better financial performance of the business. The
automation of a process can be as simple as providing
pneumatic tools verses hand tools for the assembly
of the product or can be changed from manually controlled
equipment to fully automated PLC (Program Logic Controlled)
systems by the modification of existing equipment
to add automation. Careful consideration must be given
to the evaluation of the best methods to provide this
change to the process when analyzing the production
capability.
The Process-
In
an effort to start to evaluate the needs of a manufacturing
business, CEO's executives will be involved in the
day-to-day business of manufacturing your products.
This is done initially to obtain a full understanding
of the manufacturing process that is presently in
place and the costs associated with the present process.
This in-depth study is performed with your manufacturing
employees and leads to a full and complete understanding
of the process as well as, the employee view of how
improvements can be accomplished. Once this has been
completed, an analysis is performed as to where the
best opportunities for automation exist in the manufacturing
process.
Upon
completion of the analysis, a proposal is rendered
to management with a suggested course to take for
the automation process. Once the review is completed
and accepted by management a full cost and capital
payback analysis is performed. Since the process automation
could include some capital investment on the part
of the company the payback analysis will help to guide
management on the best course to follow for this project.
Approval
to proceed-
Once
we have the approval of management to proceed CEO
will evaluate both the hardware and software needs
to implement the planned automation.
Let's
use the example of a piece of machinery that is producing
plastic labels that are individually bar coded.
-The
existing process provides for operators who need to
feed raw plastic pellets into the machine, wait until
it is molten and then start the process of making
the plastic labels. Each step of the existing process
is labor intensive and requires constant monitoring.
At the end of the process a quality inspector samples
the output of the system and makes a decision whether
the batch can be sent to the customer.
The
recommended automated changes to this exact process
that was developed by the CEO executive provides the
customer with many advantages to reduce the labor
intensity and provide automated quality inspection
as well.
-The
existing system is fitted with PLC hardware, which
is programmed to control the entire process. The raw
plastic pellets are staged and inserted by a robotic
arm with ample time to melt to the correct temperature
(which is monitored by the PLC device) to allow the
process to flow unimpeded. The entire process of the
plate manufacturing is controlled and orchestrated
by the automated control system. The plastic plates
are inspected to a specific criterion that has been
agreed to between the company and the customer. This
inspection is performed by a Vision System that is
programmed to view each piece that is completed (not
just a sample) and open gates to allow for acceptable
product to ship to the customer and other gates are
for rejects that can be classified by defect type.
Some that can be repaired will flow to a repair section
while other non-repairable rejects are sent to have
the material recycled if the process allows this to
occur. The gates are automatic controlled by the PLC
and Vision system software. The Vision System will
also interrogate the bar code labeling of the plastic
pieces and guarantee the quality of the code. If each
piece has a unique bar code label, the Vision System
will not allow duplicates to flow through. The system
can also package the product, provide outer box delivery
labeling and inventory control.
The
example is just for the purpose of describing the
process that could be controlled. The equipment exists
and CEO has actual hands on experience with this type
of automation.
-Other
processes can be as simple as the mixing of various
chemicals in the manufacturing process such as, paint
manufacturing where certain chemicals need to be precisely
mixed to develop the correct consistency for the paint
and its color. This is accomplished with solenoids
controlled by liquid level detection devices that
turn the flow of material on and off at specific process
levels. Once again automation taking the guesswork
and errors out of the manufacturing process.
The
investment and pay back-
Once
the process is in place the value of these steps can
be immediately captured. The payback comes in to the
formula not only from a monetary point of view but
more importantly from a process control point of view.
The system collects the process data, SPC information
and provides reports for analysis that will allow
further improvements in margin and profitability when
the rework and reject rates have been properly dealt
with by the manufacturing engineering team. The speed
of the manufacture of the product can also be tuned
to meet the ultimate efficiency needed to process
the material.
The
Automated Manufacturing process is not new but it
is a tool that needs to be used by business more often
to help to increase profitability and reduce all costs.
