Speed and Reliability Are the Core of Pick and Place Automation

The focal point of all packaging industries is pick and place robotics. As part of standard automated packaging systems, the picking station and place solution ensures that all required packaging tasks are done in the right manner. The features of this system include:

–  Detecting products that are to be picked from various locations on a conveyor belt.

–  Identifying any defects or faults in the products.

–  Picking products and putting them in another machine for final wrapping.

The added sensory abilities of picking stations have increased; hence the demand for them is more. Now, a picking station may also have a built-in collision control system, which functions to immediately stop a motion when working simultaneously with other machines.  The movement sensing device of a pick and place station has the ability to identify any object that is in close proximity, according to its present movement.  This avoids any unwanted collision or damage.

A picking station also has the ability to see objects that it has to pick up. To build a successful picking station for the production line, it is essential to perform certain steps. These steps help achieve the best results, and at the same time, reduce costs while increasing production rates. You can gain optimum results for your station by following certain rules and steps. The initial step is to draft proper specifications for your work station. There are various scenarios in which work stations can be used effectively. It is imperative to define each scenario, with the shape and size of the product that has to be picked from a work station.

If you use all variations of product shapes and sizes in the right manner, you can expect optimum results from the process. The goal is to make the robot move as little as possible, while performing the required tasks.  It usually takes less than half a second to perform one pick and place operation.  The lesser time a robot takes to move and do the job, the shorter would be the cycle time. This would make the entire operation faster.

Best cycle time results can only be obtained when pick and place operations move without a halt, from one cycle to the other.  The robot should be placed in such a manner that no additional movements are required, when pick and place locations are different. The payload carried by the pick and place machine needs to be optimized correctly. The lighter the payload, the faster the robot moves.

At work stations, the picking and placing robots should be anchored down. This ensures that the forces created by starting and stopping do not lead to inadvertent release of the product that is being moved.  The two types of gripping devices used for transportation of products to their destination are vacuum devices and mechanical devices. Vacuum devices are more efficient and faster due to their lower weight. Also, their moving parts do not need much maintenance.
