Shanklin M-22 Multi-Packer L-Sealer Shrink Wrapper

Automatically Orient, Group, and Shrink Wrap Products

The M-22 Automatic Multi-Packer consists of a specially modified S-24C High Production L-Sealer on which an automatic right-angle accumulating infeed has been installed for orienting and grouping a series 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, which delivers them to the accumulating section. When three products are in front of the insertion arm, it 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.
