View A Video on Automation Equipment- A Quick Introduction
Many manufacturing functions such as material handling, product forming, welding, milling, grinding, cleaning, assembly, and packaging are accomplished through the use of computer controlled, automated, and robotic machinery. Automated systems sort mail, packaged goods, and food products.
These systems may be partially manned, supervised by a production manager, or totally automated, operating without any human guidance or intervention beyond the initial programming and necessary maintenance.
Automated equipment systems are purpose designed and built to perform a specific series of tasks. These machines use systems of servos and pneumatics to operate synchronized processes on a production line or rotation. Computer control of the system assures impeccably timed delivery of materials to each station in the manufacturing process.
The item being made is conveyed through the steps as progressive operations work toward creating a finished product. Conveyor systems may consist of beltways, bucket lifts, rolling conveyors, hanging clips or hooks, or pneumatically driven tubes.
Steps along the assembly line can include extrusion, forming, welding, brazing, soldering, cutting, perforating, punching, bolting, screwing, gluing, or coating.
In a food processing plant, farm fresh products are cleaned, sorted, and separated for packaging or further processing. Ingredients are prepared, measured, mixed, portioned, cooked, and packaged by machines to provide consistent food products for distribution.
Glass and plastic components can be mixed, melted, blown, injection molded, hardened, cooled, cleaned, and packaged in a synchronous factory automation process. Massive industrial mining and forging operations rely on automated systems to move tonnage, handle material, and process molten metals into parts and components for structural, mechanical, and household items.

The Emergence of Automation
Since the dawn of the Industrial Age and the advent of Henry Ford's assembly line, great strides have been taken toward product automation. New technology has made the unmanned assembly line a reality that Mr. Ford probably could not even imagine.
Henry Ford is known as the Father of the Assembly Line, but Ransom Olds actually received the first patent for it, in 1901. Olds' line required workers to manually move the vehicles from station to station, but productivity was still increased by 500 percent over previous assembly methods.
The first successful automated bottle blowing machine was introduced in 1905. A total of four men were able to produce 17,280 bottles in twenty four hours - versus - six men producing 2,880 bottles in a twelve hour shift. The cost plummeted from $1.80 per gross to about 11 cents per gross.
Henry Ford's famed assembly line began in 1913. His cars were placed on a conveyor rail, bringing the project to the workers, instead of the workers going to the project or dragging it to its next destination. He was able to boost production from one car every twelve hours to a car every hour and a half.
Expansion to the West caused a demand for printed media, which created the need for quality paper manufacturing on a huge scale. As paper dries, the drying rate must be slowed to keep the paper from wrinkling. A sectional electric drive control was first developed in 1919 to facilitate the progressively slower drying times, providing consistently smooth paper.
In Japan, in 1930, an accurate electrical timer with micro-switches and protective relays was invented. This development was the basis of synchronized automation as it allowed machines to interact without human intervention.
Following World War II, the rebuilding of occupied Japan gave rise to new factories with cutting edge technology and allied support. The finest state-of-the-art equipment was installed, and by 1952, Japan was the world leader in automated manufacturing, particularly production of automobiles.
The 1960s ushered in the use of robotic arms that could perform simple tasks such as lifting, clamping, and turning.
In 1969, Victor Scheinman introduced a 6 axis robotic arm, known as the Stanford Arm, which could move and assemble parts repeatedly and continuously, allowing multiple functions to be performed by a single unit. Prior to this, each function had to be performed by a single unit at a separate station.
The 1980s saw the dawn of the Computer Age. Computer Integrated Manufacturing (CIM) and Computer Numerical Control (CNC) manufacturing became indispensable to industrial design of every faction.
By Y2K, everything, from the tiniest pill to missions to Mars, were being calculated to present the best product in the most efficient manner. Automated assembly machinery had to be designed to faithfully reproduce these designs in the same efficient manner.
The 2010s ushered in 3-D printing or additive manufacturing (AM) which used computer controlled designs from an AM file to create three dimensional objects. The "printers" deposited sequential layers of binder materials onto a bed of powder in pre-programmed patterns, via inkjets.
What Automation Means For Industry
The goals of factory automation are safety, cost effectiveness, production quality, speed, consistency, and convenience. By removing the human element, these goals are more likely to be achieved.
Manufacturing facilities can be dangerous to humans. Heat, cold, toxic fumes, corrosive liquids, caustic materials, and sharp or abrasive items, can cause injuries to workers on a production line. Repetitive motion injuries, lifting injuries, slips, trips, and falls also put workers at risk, raise insurance rates, and lower productivity.
Replacing human workers with automated systems greatly reduces accidents and injury in the workplace, as well as eliminating the direct impact of paying wages. Machines can work continually, eliminating downtime for employee breaks and shift changes. Automated equipment is fast, providing consistent quantity and quality of work, at rates faster than humans can perform.
Less overhead, fewer errors, and faster manufacturing with minimal waste equate to cost effective production.
Consideration must be given to the possibility of machine malfunction, which could result in catastrophic repetition. In a dark system, one which is completely automated with no supervisor on hand, a single glitch in the system, such as a defective part, breakdown of equipment, or power disruption, can create a domino effect that topples the entire line.
Safety has been designed into these systems with the use of electronic monitoring devices that detect malfunctions, whether they are mechanical or environmental, and react accordingly. Remote visual monitors allow video surveillance of the equipment to reassure management of proper function of the operation, keeping man hours to a minimum and production at its maximum.
What Automation Does For Industry
Computer aided design (CAD) is the programmed design of equipment, through the use of computers, to create a design on paper that can then be replicated in a three dimensional fashion. These designs include plans for production procedures and processes to be performed by machines, rather than humans.
Computer aided manufacturing (CAM) is the method of using computer controlled mechanisms to perform some or all of the steps on an assembly line, with human supervision or intervention.
Computer integrated manufacturing (CIM) is a manufacturing method where the machinery is entirely computer controlled, operated, and monitored.
Computer numerical control (CNC), or simply numerical control, is the method of programming automated equipment to function according to encoded commands without being manned by workers to flip switches, turn knobs, or place parts.
Additive manufacturing (AM) is also known as 3-D or lenticular printing. The additive material is deposited by inkjets onto a bed of powder in layers. The positioning of the deposits is computer controlled to replicate a three dimensional object from a 3-D model or electronic data file. The deposits can joined together and solidified in any shape or geometry. This is ideal for rapid prototyping of parts to be manufactured on an assembly line.
An automatic assembly line uses integrated equipment with precision timing. The bulk feeders must material handle products along the line so that each step in the process is accurately aligned for work to be accomplished at the next station. These steps are controlled by actuators that translate control signals from a pre-programmed design and activate the machinery, which, in turn performs a precision task as per the controllers.
Robotic automation allows for multi-axial functions to take place at one production station. The robotic arms load and turn screws and bolts to precision torque specifications, position and insert parts, provide pre-measured quantities of adhesives to precise locations, or perform other complex manufacturing tasks, such as sorting, folding, sealing, and crating.
Production of metals for manufacturing is facilitated through the use of huge bucket conveyors that carry raw materials that are dumped into crucibles that are conveyed through smelting furnaces into forming processes that may include molding, casting, or extrusion. Welding equipment can be integrated into automation production. Automated stations may spot weld metal or plastic parts together. Robotic arms may produce lengthy bead welds or perform varied cutting operations.
Automated Manufacturing And You
Because every function of automated manufacturing is product specific, it is important to find a company that can design custom automation equipment that meets your needs. A good designer can help you create an automation system based on the size of your facility, the number and complexity of steps required to produce your product, and the quantity or range of production you need to achieve.
Your system should be integrated for maximum production levels, custom manufacturing capabilities, and systematic changes that may take place with growth and development of your business.
Scheduled maintenance of your automation system is imperative for continuous operation. Breakdowns in the system should be addressed before they happen, to minimize damages. Making sure your system is appropriately cleaned, lubricated, and all fasteners and electronic connections are firmly attached, on a regular basis, is key to successful operation. Checking controls and alignments will keep the assembly line moving forward.
Industrial safety and cleanliness standards for automated manufacturing are set forth by several governing entities and committees to ensure safe environments for workers, materials, and products.
Current Good Manufacturing Practices (CGMP) or Good Automated Manufacturing Practice (GAMP)is a set of processing guidelines, as well as a committee to ensure adherence to those guidelines, for the International Society for Pharmaceutical Engineering (ISPE). Their purpose is to regulate quality and consistency standards of pharmaceutical drug processing to assure proper, safe, and effective medications are being produced.
U.S. Department of Labor standards are outlined for operator safety, equipment safety, food safety, and consumer safety.
OSHA provides Federal Register notices, which are rules or proposed rules with regard to occupational safety, directives, official interpretations of standards, and national consensus standards (average national performance of tasks)for mandatory and non-mandatory compliance.
American National Standards Institute (ANSI) and American Society for Testing and Materials (ASTM) address machine and tool safety standards for manufacturing equipment and materials.
The Food and Drug Administration (FDA) maintains standards for food and drug processing to regulate the cleanliness, quality, and safety of food production equipment, products, packaging, and distribution.
Your equipment provider should be able to offer information and services that keeps your operation in compliance with these guidelines.
