Robot-centered work cell

In industries, the working unit of a robot can be prepared in three different arrangements such as:

In this article, the first arrangement (Robot-centered cell) is described briefly below:

Design of Robot-centered cell:

Robot-centered cell is one of the commonly used layouts in the industrial applications. In this arrangement, a single robot will be incorporated at the center of the work cell for performing operations on several machines that are set in a semi-circle form. This type of work cell is shown in the below figure.

This arrangement was organized because in 1960s a single robot was used to perform only one function, either carrying out a production process or examining a production machine. Those times, the robots were mostly employed in several operations like die casting, loading and unloading of parts, etc. where the usage of robots was very low when compared with the machine usage times.

This inequity in performance was highly occurred in the metal machining operations. During this process, a robot remains inactive for a longer period. As a result, Robot-centered cell was introduced to maximize the usage of robots.

Application of Robot-centered cell:

Arc welding operation is an application of the Robot-centered cell. In this process, a robot is used to perform the production process, instead of examining the production machine.

Additionally, this operation requires pallets, conveyors, and other devices for providing the work parts to the cell. These devices will place the work parts in a preferred area for appropriate lifting. Human workers are also employed for performing the part loading and unloading tasks.
