How to Choose Between a Cobot Cell and an Industrial Robot Cell
The automation of case packing and palletizing has emerged as a strategic aspect whereby manufacturers strive to attain high efficiency, consistency, and labor utilization. These discussions are dominated by two prevalent traditions in the automation world: collaborative robot (cobot) cells and traditional industrial robot cells. They could both be valuable, though the right decision will be based on the needs of the production, risk, and long-term objectives of operations. The difference is marked by manufacturing managers, operations directors, and plant engineers to make sound decisions regarding automation.
Understanding the Two Approaches
Cobot cells can be used in the case of collaborative robots, and are kept under a restricted level of guard to ensure the safety of their operations in crowded areas around people. The systems are usually easy to install and recycle as well, which is appealing to low-volume or flexible processes.
On the other hand, the high-speed robots are required to drive the industrial robot cell thathandles 24-hour loads. These systems tend to need safety fencing, more extensive integration, and are much more throughput and life span rich.
They can also be interchangeably used in robot palletizing solutions and robot pick and place solutions, although they might require different operations.
Throughput and Payload Requirements.
Throughput is one of the most significant characteristics of a decision. Cobot palletizing systems are less fast, and are generally designed for mid-speed and lower weight. A cobot may be everything that you need when cases are smaller, changeovers, or variable SKUs.
The industrially applicable robot cells are excellent for high volume and speed. Their power is capable of operating on heavier loads, higher stack heights, and longer cycles without fatigue. Industrial robots are more apt where there is more than one shift or 24-hour production to address the needs of performance.
Key consideration: In some cases, an industrial robot may be the best option in the long run when your palletizing line already has the throughput capacity pushed to the limit, or you think it will soon.
Safety, Footprint, and Integration
Here, the cobots are made to possess inbuilt safety in the form of force control and speed control. This will enable them to work with less guarding, which will result in a low cost of installation and the avoidance of layout considerations. This can be one of the significant benefits of smaller floor-area facilities.
The industries need safety fencing, light curtains, and formal risk assessment in robots. This not only complicates the initial stages, but, on the other hand, enables the robot to work as quickly as possible without reducing the velocity. The extra footprint is never a problem in good plans.
Customized automation is an asset of both systems in terms of integration. The case infeed system, conveyors, pallet dispensers, and end-of-arm tooling are essential product- and process-specific and independent of the type of robot.
Changeovers and Flexibility.
Flexibility is another feature commonly linked to Cobots. They can be redeployed, reprogrammed, and modified more easily than product mix changes. This flexibility has the ability to shorten the downtime and design time of plants that have high SKUs or seasonal plants.
Practical insight: Flexibility is the most crucial one in the low to medium-volume environment. Large volumes are more important to stability and speed than reconfigurability frequency.
Lifecycle Cost and Reliability.
Cobots may be less expensive to purchase in the short term, but they may not be less costly over the course of the system. Working at full load or speed could promote wear and decrease reliability. This can result in an increased maintenance intervention in the strenuous environments.
Choosing the Right Solution
There is no universal answer. Cobot cell could be the solution to facilities that were embarking on automation, labor crunch, or single low-rate line automation. Manufacturers who would be interested in an industrial robot cell are those who already have strategies in place to automate, with a high throughput need, or long-term growth strategies. The manufacturers would work with a partner, an automation professional who will assist in maintaining the compatibility of the system with the production objectives, safety, and expansion. The type of robot does not pose as much of a problem, as the sound system design and proscenium requirements.
Conclusion
The decision to pack and palletize cases with a cobot cell or an industrial robot cell is a more strategic one, rather than a technical one. Through measurement of throughput, safety, flexibility, reliability, and lifecycle cost, manufacturers have an opportunity to choose a solution that can support both the operational goals of the present time and increase in the future. The correct decision is that which suits manufacturing processes, instead of the fad in robot palletizing and custom automation.
