How does it work the Automatic Stretch Hooder MH3.
Our automatic stretch Hooder machine MH3, which represents a new concept of goods protection, has an operation as simple as safe, the equivalent to performance and strength tipical of all Messersì Packaging products.
The machine receives the products to be wrapped by the entering conveyor, the pack must be centered crosswise to the direction fo the motion; the product, on the dedicated conveyor of the machine, must be stopped centered under the hooding machine.
An electronic control is provided to avoid collisions of the hooding arc with the product in the event that it presents protrusions or in case it turns out accedentally out of shape.
Basically, the machine cycle can be divided into two main phases. These cycle phases are normally carried out during the phase of introduction into the stretch hooder machine MH3 of the new product to be wrapped or parallelly to the phases of the common cycles, therefore they not influence the machine cycle time.
First phase – Preparation of the hood
The preparation of the hoods take place in the upper part of the stretch hooder machine by using a particular system of special rollers that unwind the film. The reel begins the unwinding and, to optimize the film consumption, the sizes of the hood are automatically established by an external reading system of the machine itself (Optional).
The welding and cutting unit prepares the hood by welding and subsequently cutting the film. Once prepared, the hood is transported by the mechanical gripping system; the opening of the hood in tubular happens by the transversal and longitudinal movement of the four clamps, synchronized and electronically controlled.
Second phase – Application of the hood
Once the required mechanical opening has been reached, the clamps model the correct inlet rectangle of the hood on the product and apply it on the pack by descending the arch, positioning it up to the base of the pallet.
The mechanical transmissions of the vertical movements of the hooding machine are by chain, with anti-fall control system of the moving group. The dedicated converyor made for the stretch hooder machine is normally specific for it, it can be equipped with a lifting
