Automatically Orient, Group, and Shrink Wrap Products
Shanklin M-22 multi-packer L-sealers makes a single package of multiple products on the shrink machine.
This automatic shrink wrap machine offers an accumulating conveyor and specialized right-angle inserting unit for feeding groups of products into the sealing area. Once the seal is made, the conveyor moves the pack to the shrink tunnel for a neat, tight, fully overwrapped grouping of products.
The basic components of the infeed are a product feeding conveyor, an accumulating conveyor, and a specialized right-angle inserting arm that feeds the grouping of products into the sealing area.
Production Process
The Shanklin M-22 Multi-Packer makes a single package of multiple products - for example, six items oriented in two rows of three.
- Products are fed onto the infeed conveyor that delivers them to the accumulating section.
- When three products are in front of the insertion arm, the arm moves them part way to the sealing area and returns to the retracted position.
- After three additional products are moved into the accumulating section, the insertion arm moves all six into the sealing area where they are overwrapped and sealed.
- Sealing complete, the discharge conveyor moves the pack to the shrink tunnel.
When the package leaves the shrink tunnel, it is a neat, tight, fully-overwrapped grouping of products. - To create groupings of different quantities, adjust the machine and select the number of strokes desired.
