In certain types of conveyor systems, there is a need to accumulate product – i.e., to stop each individual product on the conveyor, whether to create a buffer, allow an external process such as labelling or filling, or create a FIFO queue.
Traditional accumulation methods are either low pressure or a full stop. Low pressure accumulation allows products to drive into each other at the end of the line until a saturation point is reached, in which case the conveyor switches off. This leads to the product being pushed into the product in front of it, and depending on weight, speed and the length of the saturation zone, this could lead to product damage. This is called ‘line pressure’, and causes damage to the product and/or packaging, as well as increased wear and tear on the conveyors.
This additional wear and tear reduces conveyor efficiencies, and increases the day-to-day cost of ownership from both a maintenance and input cost point of view.
Siyamuva zero-pressure accumulation (ZPA) conveyor modules are the answer.
Our ZPA modules utilise various types of drive mechanisms:
These mechanisms are used to create zones for individual product transportation. Each zone is controlled by a roller with an internal drive motor, control card and sensor. This means that each zone has its own motor and sensor and, depending on the type of system and the specific requirements, there may either be a control card per zone, or a card that controls multiple zones. These cards are also able to be set up in a closed network or operated by a PLC. All motors are 24V DC, replacing the commonly-used external motor / gearbox.
As each product is transferred from zone to zone, the cards communicate to let the zones know if there is a product in the next zone; if there is, that zone will not transfer the product into the next zone until it is clear.
Each zone length is calculated according to the following:
