The history of pallet inverter and the evolution of this pallet changer machine
Pallet inverter is also known as pile turner for the professional defination. It's the machine to turn over full pallet loads of products and package 90 degrees or 180 degrees. The reason for the up-ending is to have quick access to the bottom of loads without unloading the products on the pallet. Make the change of the damaged pallets and slip sheets, sometimes also for the damaged products.
For the subject of the history of pallet inverter, we might need to get back to 1956 first. In 1956, American Ohr first had the design of the idea of a pallet inverter. It was named as skid inverter and he applied to the United states patent office for his benefits.
This is the earlist document that we can track for the invention of pallet inverter. From this document, we are able to see that the machine was only a hand use equipment to turn over a wooden skid, there was even no such use of electric motor and this might because of the background of that age and time. But it in deed is the original idea of our modern pallet inverters we use today.
Later in 1981, there was another designer applied his patent to the United states Patent Office. This time the machine was named as "pallet inverter".
From this document, we are see that the designer started to apply hydraulic power system and tooth rack and sprocket to the machine to save man power.
At that time the main purpose of using this pallet inverter is for changing the damaged pallets or slip sheets, and sometimes, users need to transfer their goods from plastic pallets to wooden pallets for shipping.
Starting from the 1990s, life is becoming abundant. Different processed food and snacks were becoming popular, sea food is almost critical to everyone. So the cold chain business was growing up as these products need rapid freezing. The freezer spacer is necessary to seperate each cartons and boxes on the pallet, but they also need to removed prior to shipping. So, the pallet inverter again to developed as a pallet retriever which rotate 90 degrees to allow easy removal and reuse of the freezer spacers.
Today, as the development of new technology, our pallet inverter has great improvement to perform different jobs on one machine and there is also much more convenient operation and protection regarding the safety of the users.
