Time and space are important factors when bringing together lines of product flow to one main operational conveyor. Of course these are aspects to efficiency in any operation, but especially when it comes to manipulating product in one coordinated line of flow for additional action. For example, products may need to be positioned and subsequently labeled after coming from different production lines. Sometimes the product lines may consist of different sizes of packages. When this situation exists, it is referred to as chaotic packaging flow, and requires system flexibility to adjust to the requirements.
Regardless of chaotic or consistent packaging operations, as things move along and lines are merged, various types of indexer methods may be employed to preclude traffic jams or collisions which could result in product damage or system down time. Neither of which is acceptable for efficient operations. Indexers are designed to momentarily interrupt movement on one conveyor to provide for smooth transitions, separation, and commingling of product lines.
Some indexing or singulation is sometimes accomplished by multiple side-by
