Tatiara Seeds have developed a new seed processing facility in Bordertown, SA and commissioned Kockums Bulk System to supply an Okura Robotic Palletising system for bags.
Tatiara Seeds required a system to palletise their wide range of client sacks in a multitude of layer patterns, and at the desired rate onto three different types of pallet. It was necessary for Kockums to minimising the overall footprint allowing good forklift and operator access. Also, provision had to be made for a future fourth bagging line.
Bags are supplied to Tatiara Seeds by their clients, so the palletising system needed to be flexible enough to cater for this large variety. Okura's OXPA software provides a simple HMI for the operator to either call up a preset program or he is able to quickly input sack and pallet criteria allowing OXPA to determine all the possible layer options that are available.
Programming can be handled either locally at the robot, on a PC offline for later download, or remotely via modem link. The Modem link also provides system monitoring or troubleshooting capabilities from Kockums Bulk Systems head office in Melbourne should the need arise.
The system configuration is such that the A1600III Okura Palletiser has been installed in the centre of the building. From three corners of the building the processed seeds feed manual baggers which in turn feed the palletiser at 400 bags per hour. A fourth line is planned for the future increasing the system capacity up to 500 bph. Filled bags are kicked from the closing line conveyor to a bag flattener prior to palletising to promote a stable pallet stack. Okura's fully sealed drive mechanism was also an important consideration in this potentially dusty environment. The robot hand is arguably the hardest working component of the palletising systems. Okura's bag hand has been specially designed to provide excellent support to conditioned bags. This is especially important with bags containing free flowing material like seeds, as bag deformation can jeopardise the pallet stability. Okura's bag hand is well proven over many years and other Kockums installations have exceeded 10 million bags per hand, and still counting.
Pallets are introduced to the system by means of a drive in-drive out-type conveying system, dedicated to each bagging line. The pallet conveyor is designed to accommodate standard Chep type, export version, and a large custom type pallet.
Safety is paramount; the system has been designed in accordance with the requirements of AS4024 Safeguarding of Machinery.
The complete system was fully built and tested at Kockums Bulk System prior to dispatch minimising the final onsite installation time.
