We are delighted to have been selected as the supplier of choice for a new Automatic Roll Storage System.
Rolls of raw materials are currently stored in bundles adjacent to the customer’s existing splicer machines. They are individuality removed and then manually loaded onto the splicer mandrel by an operator. Our brief was to automate the storage and retrieval of raw material bundles in this process.
Our system will accept roll bundles from the customer’s existing Automatic Guided Vehicles (AGVs). Product data will be sent via host network to the our PLC giving the width and diameter of the rolls. We will verify this data from the host network by scanning the roll diameters with an ultrasonic sensor mounted to the underside of the guarding. If the diameter does not correspond to the information sent by the host network the system will stop and an error message will be sent to the Host and displayed on the HMI, indicating that manual intervention or inspection is required.
Our tried and tested automatic Cartesian crane system is comprised of a free standing steel framework incorporating a powered servo belt driven down shop rail system. The rigid Z-Axis passes through a central linear axis and is servo driven for raise and lower.
The storage area will be a racking system with 6 raw material storage positions angled slightly back for roll stability. Each pocket will incorporate individual “V” conveyor sections on which the individual rolls will be placed by the automatic crane system. When an individual roll is deposited it will be cradled for support and indexed back to create space for the next roll to be positioned. This process will be repeated until a full bundle of 6 rolls is present. The crane will then traverse to a predetermined position where it will transfer the raw material roll to the raw material loading robot.
Our expertise in this area coupled with its strong track record in designing and delivering such solutions was a deciding factor in the customer awarding us this exciting new project.
