Inline Shrink Wrapper Machine

After filling, capping and labeling, product containers are transported into the shrink wrapping equipment by means of inline conveyor which delivers the product in 2, 3 or 4 lanes onto collation table. Photo eyes mounted on the conveyor detect flow of the products, The pneumatically operated bottle outgate cylinder stops a set of bottles, after target products are achieved, the outgate cylinder withdraws itself and ingate cylinder closes. Products are transported to wrapping unit. Shrink wrapper machine commonly uses two reels of film which are joined to form a web. When the product intersects the film web, it passes through the seal frame and moves onto the collation table. As the product moves through the film the shrink wrap packaging machine detects film usage and starts the powered film unwind feeding film. After enough film is fed the powered film unwind system stops. As the product moves through the seal frame, the carriage moves the seal frame forward with the product and the seal bars close to form a film sleeve around the product. The seal bars cut and seal the film. After the seal dwell timer times out, the bars open and the carriage returns to its home position. The product now in a the film sleeve continues moving forward across the conveyor and transfers onto the shrink wrap tunnel conveyor. The medium-speed shrink wrap machine tunnel conveyor moves the product through the shrink tunnel chamber. The film shrinks evenly around the product as it travels through the tunnel. When the shrink wrapped product exits the tunnel the film is still somewhat tacky. A cooling section located at the exit of the tunnel blows ambient/cool air onto the film as the product passes. The air cools the film and allows for faster product handling. The fully shrink wrapped product then transfers onto the customer’s conveyor completing the shrink wrap packaging cycle.
