SH-1 Stretch Hood Wrapping Machine

The stretch hood machine packs palletized products.

Operation Procedure

1. Palletized products are transferred to the machine via transfer conveyors. The system automatically detects the height of the products with a sensor and determines the necessary length of film to pack the products.
2. The draw rollers pull one screenful of the film to the lower end of the vacuum pickup.
3. Gusset sections of the film tube are pulled apart by vacuum suction, then, opening arms which are individually equipped with a clamp unit firmly grip the film tube at its four corners.
4. Each clamp unit, keeping a firm hold of the film, moves outwards in order to spread the film evenly over the contour.
5. Four winder fingers, mounted on the extender, move horizontally to the position where they can enter the opened film and ascend up to the specified position. The winder expands again to the size of the opening to receive the film.
6. The winder rollers move toward the fingers to hold the film between the rollers and the fingers.
7. The draw rollers draw the film by the length additionally required. The winder rollers haul in the film and wind it around the fingers in the accordion form.
8. When the film is sufficiently drawn, the rollers stop and the film end is impulse-sealed and cut. Temperature is controlled by the controller of the high reply.
9. When a series of operations have been successfully completed, the extender stretches to accommodate the products with a good margin.
10. The extender descends, and the tucked film is unfolded to cover the products. The winder rollers return to the origin when the timer counts down from the start of descending. (Please refer to the operation process illustrated at the far right)
11. On reaching the pre-set position, the winder rollers move to the fingers and hold the film to prevent it from slipping off from fingers. Keeping this state, the extender further descends to below the products and releases the film, which is shrunk to smaller than the product size. By this, the leading edge of the film is securely pushed into the space below the pallet to stabilize the products on the pallet.
12. The extender expands to clear the products and ascends to the origin.
13. The packed products are discharged by the transfer conveyor while the next products to be packed arrive at the set position on the machine (return to step 1)
