Industrial Arm Robot Applications
Some industrial arm robot is more suitable for specific application whether is milling robots, assembly-line robots, a painting application, palletising robots, welding robots and other robot applications. A robot integrator can help you to choose the right industrial arm robot. Now is the time to invest in robotic because price had declined on the last years. Why is important to consult with an integrator?
Benefit of Robot Integrator
Some robot manufacturer just want to sell robots. New robotic users do not realise that by consulting with a robot integrator will save time and cost. Some of the benefit of robot integrator are:
- Integrator understand the market
- They can suggest more suitable automated robot equipment
- Robot integration experiences
- They work with all robot brand, it means they can help you to choose the robot that best fits the specification for the manufacturing process
Take advantages of their vast expertise and consult with an integrator before you decide to purchase a robotic systems or see ROI Robot System Value Calculator.
The amount of robot that a person can supervise really depends on tasks of the operator For example, if the robot cell has a turntable and the operator is loading one side whilst the robot is working on the other and the cycle time is quite fast the operator is busy loading and unloading that one robot.
Automated Robot Systems
Alternatively it could be an automatic loading from a conveyor in which case the operator is just supervising the machine and in this case it could be 20+ robots. In short, it all depends on the level of involvement of the operator and there is no specific number of relationship between the number of robots and the number of operators.
The return on investment is a calculation where the current operating costs of manual operation vs the initial and ongoing costs of replacing these manual operations with an automated sequence with a robot at its base.
Robotic Systems extra costs
The extra costs for putting in place the robotic systems against the yearly savings on salaries, reduced downtime, increased productivity, reduced scrap etc to arrive at the number of years before those savings have paid back the initial investment. By reaching that point, the savings become operating profit allowing the production at a lower unit cost. If this comes out at anything between 12 to months and 36 months then the decision to invest becomes an easy one.
Ideally, this should be a win-win situation. You know that there are jobs that no one really wants to do. These are those repetitive, tedious jobs that require a lot of monotonous action from the side of a worker. If it is always the same task you could use an automated solution tailored specifically for your needs.
The situation where a factory needs to be more and more flexible is becoming more and more common. In these cases, a re-programmable robot which can be used for different tasks is the right solution. In many cases like the ones mentioned, it is wiser and cheaper in the long term to use a robot than to hire a worker.
And of course, there are jobs that can’t be done by a human-like lifting very heavy weights or working in conditions unsuitable for human life.
When selecting a robot it is important to consider the number of the working envelope (reach) and carrying capacity (payload). It means the work area is the volume of working or reaching space.
Some factors of a robot’s design like configurations, axes or degrees of freedom, influence its working area. When considering the working envelope of the robot is necessary to consider how the parts to be worked or held. The robot may reach the part behind, for instance, it means that the wrist will be back on itself and it is going to require a bigger envelope than if the wrist was able to work without this requirement.
Robot Payload Maximum Payload is the weight mounted on of the robotic wrist, including the EOAT (End-of-arm-tooling) and work piece in the case where this is held in the EOAT in the case of a gripper for example. It varies with different robot applications and models.
Maximum Payload Chart
All robot manufacturers include a chart showing how the maximum payload value and most manufacturers have an application to allow entering the details of the end tooling and then calculating the payload capacity needed.
Typical costs outside of the main purchase include – spare parts, yearly service and maintenance, yearly replacement/wear items. Therefore, these costs are after the robot cell is up and running is mainly costs related to the maintenance of the robot or spare parts.
Low Robot Cost
Fortunately, robot cost is very low as the robots run for thousands of hours before any need for maintenance. Each manufacturer include his own maintenance schedule based on hours of running or months.
We can supply custom-built robotic cells equipped with new industrial robot or refurbished robot from any robot manufacturers such as ABB, FANUC, KUKA, MOTOMAN and others. These installations can range from a single robot cell to more complex multiple robotic systems processes.
Affordable refurbished robots
Alternatively, you may source the robot yourselves and we can carry out the robot integration. The industrial robot models vary in payload and envelope, giving you a large choice when it comes to finding the exact robot for your process. We have access to all the leading robot brands and offer highly reliable, effective, and affordable refurbished robot. Contact Us!
Robot Arm is the term used for manufacturing applications when refers to the industrial robots. Industrial robots are classified by the degrees of freedom (type of movement), and manufacturing application or process.
Automated robots have different type of movements. The most common are:
- Cartesian Robots – Robots have three linear movements based on the coordinate system (X,Y and Z).
- Articulated Robots – Robots with 6-axis or movement
- SCARA Robots – Robots have 4-axis (three movements and a vertical rotation axis)
- Collaborative Robots – new generations of robots made with high-safety standards because they can work alongside humans
For the majority of robot types these maintenance periods will be restricted to oil changes for the gearboxes for each axis and where applicable drive belt re-tensioning and examination. Oil seals will also need examining and possibly some re-greasing on the cable runs through the main axis.
Robot maintenance reduce downtime
The amount of downtime that the production can accept determine whether to buy spare parts or which spares to purchase. For critical applications it may be better to stock essential spares like drive modules, safety boards, teach pendants (in case of breakages) and possibly an exchange wrist unit.
Manufacturers take advantages of the robot applications using 6-axis robots for the robotic systems, example of the main type of automated robots are welding robots, assembly robots, painting robots, material handling robots, and milling robots. Industrial arm robot helps manufacturer to save time and costs.
A typical, single robot cell with a reconditioned robot is going to come out around £60,000. Obviously, this amount vary depending on the complexity of the process and particularly the EOAT (end-of-arm tool) used, but generally, most single-robot systems will fall into this cost range.
An example of Single Robot Cell will include:
- Industrial Arm Robot based on payload capacity and reach based on company’s needs
- Robot End-Of-Arm-Tooling or Gripper (*)
- Control panel including PLC or Operator Interface Screen (HMI), safety circuits, motor starters VSDs, etc.
- Cell guarding
- Customized engineering for your system to complete the desired process
- Safety equipment
- Some auxiliary equipment such as conveyors, deburring equipment, etc.
- Fabrication, assembly, setup, toolpath programming, tested before shipping
- Installation and commissioning of the cell
- Integration with your existing equipment
- System-specific operator training
- Programming or robot simulation based on customer’s requirements
