The video below shows a palletizing robot that stacks 50 pound paper valve bags onto a wooden shipping pallet located on the floor per the programmed bag placement design. This robot was added to an existing bag filling system to reduce labor costs and increase automation.

Frequently Asked Questions
How does this palletizing robot fit into a bagging operation?
The robot can be retrofitted into an existing bag filling system. In the video, it is centered between two bag palletizing stations, one on the right side and the other on the left side. Filled bags are placed on the left side until the pallet is filled. Then the robot switches to the right side until that pallet is filled. The fork truck operator enters the right side, and / or the left side as needed to remove the filled pallet and to place an empty pallet on the floor.
Automated palletizing systems yield the biggest return on investment.
How much floor space does a palletizing robot require?
Ballpark number is a 20 foot by 20 foot area.
What bag sizes or weights can be palletized with this robot?
Robotic palletizers can palletize bags weighing 20 pounds to 110 pounds. Tool change out is required, if you want to palletize different sized bags with the same bag filling system. The robot can also stack pails, boxes and drums on shipping pallets.
How does the robot pick up the bags without breaking them?
It uses an attachment or tool that reaches under the bag when it is on the feed roller conveyor, also known as the palletizing conveyor.
How does the robot know when to start and stop?
There are a series of electronic sensors along the infeed conveyors that send a signal to the robotic arm processing computer. These signals inform the robot arm of the location of the incoming filled bags on the conveyor.
Is it difficult to learn how to use the robot?
For the operator, there is no learning curve. The operator removes the filled pallet and replaces it with an empty pallet. There is nothing else to do once everything has been programmed.
How are updates made to the robot system software?
Updates maybe required if the bags change or if the pallet size changes, but usually no updates are required.
Do you have to make a lot of adjustments over time because things “get out of whack”?
Yes. Some of the sensors on the robotic arm and on the infeed conveyors may have to be replaced on an annual basis. In dusty and or dirty locations this sensor change out may be on a monthly schedule.
In house maintenance staff can replace the sensors and make adjustments.
Can the robot be moved easily if you want to use it in another location of the factory or at an entirely off-site location?
No. Moving the robot can be done but it will be a large project.
Will the palletizing robot work in very hot or very cold locations in Texas, Oklahoma, Arkansas, Louisiana, etc.?
Yes. Temperature does not affect performance.
