Automation for pallet-strapping operations has been made possible with the invention of machines designed to fully perform a task. An automatic pallet-strapping machine is the scaled up version of a box-strapping machine, as it is used to secure an entire pallet rather than small-sized boxes. It is equipped with a bigger arch, which may be as high as 200 cm and with a width of up to 150 cm, and these dimensions are in accordance with the standard pallet size used in the shipping industry. Additionally, machines are built sturdily using aluminium alloy, which only serves to increase the
longevity of the equipment.
An automatic pallet-strapping machine has many features that assist in the complete automation of the machine. It has a PLC control panel which processes all the digital input and helps with the customization of the operation. This feature is essential for the convenience and flexibility of the equipment. It also has an auto reset button which comes in handy for reprogramming the settings. The possibility of adjusting tension up to 90 kilograms for each pallet is another feature that helps with securely tying the straps. One can use straps of width 9, 12 or 15 mm with this equipment. The strapping efficiency is largely dependent on the number of pallets that can be strapped per minute. One pallet can be fully wrapped in 5 to 15 seconds, depending upon the model. High-efficiency models may even strap up to 27 pallets per minute. The machine has an auto-loop ejector which can operate through the pallet-void strapping of a pallet vertically. For side strapping, the machine also has loop ejectors on the sides which can operate at various heights to allow strapping at different points on the pallet.
The advanced features of an automatic pallet strapping machine consist of a roller conveyor to deliver the pallet to the strapping site and a turntable to allow the sealing from every side. The straps are easy to change, so that the operation is not halted for a long time. Some models are also equipped with a power-saving feature, which shuts down the machine once no pallet is sensed for a pre-set time period. All in all, the machine has full control of the strapping task and is of great use for shipping operations.
