[vc_row][vc_column][vc_column_text]A complex and specialised system, automatic sack palletising isn\u2019t as straightforward as it looks.<\/p>\n

<\/p>\n

Placing products onto pallets by hand is time consuming and physically demanding work. It\u2019s a natural progression to employ a robot palletiser for busy production lines. But how do automatic palletisers create the perfect stack? It seems simple, but there are a few key steps to loading a stable and consistent pallet. Each of the following steps is programmed into an automatic sack palletiser<\/a> for maximum efficiency.<\/p>\n

1. Bag preparation is critical. The bag or sack needs to be as consistent as possible, so using rumble rollers, flattening roller or tapered belt pressing \u2013 or even a combination of all three \u2013 will ensure the sack is flat, before being collected.
\n2. The sack palletising gripper then locates and picks up a bag from a layer table or conveyor \u2013 each can weigh hundreds of pounds. It holds the sack firmly, without puncturing the packaging, and doesn\u2019t allow the product inside to move during the pick and place cycle.[\/vc_column_text][vc_btn title=\u201dFind out more about PALpack\u2019s sack palletisers\u201d link=\u201durl:https%3A%2F%2Fwww.palpack.co.uk%2Fproducts%2Fsack-palletising%2F|target:_blank\u201d][vc_column_text]3. The pattern of sacks on the pallet has to be laid out in such a way that the shape remains consistent.
\n4. The speed of the robot will vary, slowing slightly when moving sacks and working at full speed when the gripper is empty.
\n5. Each layer is measured for height variation to avoid a cumulative error.<\/p>\n
