Capsule application

With the right equilibrium between innovation and tradition, Fimer develops bottling machines for the food and beverage industry. Its technical team is keen on study and whole bottling line projects satisfying any production requirements, from the small winery to the large-scale beverage producers

The company proposes an optimized capping system which consists of three different types of treatment: the distribution of capsules, the rolling, and the thermo-smoothing.

The capsules are contained in an inclined storage, with a capacity of up to 700/800 pieces, and they are distributed onto the infeed screw feeder, via a single-head distributor activated by a “no cap/no capsule” photocell. A plc system synchronizes the functioning of the distributor through the movement of the capper.

The neck of the bottle is centred by a pneumatic piston and the cap is pushed inside the rotating distributor by a direct jet of compressed air; subsequently, the rotation of the distributor places the cap onto the neck of the bottle and a small pneumatic piston perfectly arranges the cap, preparing the upper part for smoothing. The distributor must be changed for caps with different diameters and lengths.

The smoothing of tin or polyaminate caps takes place by means of a roller with hard plastic wear-resistant rolls featuring self-lubricating bushes which minimize the resistance to rolling on the capsules. The rotation speed is set between 1000 and 1500 rpm, the smoothing tension can be comfortably adjusted and the direction of rotation can be clockwise or anti-clockwise. Therefore, the smoothing of shrink capsules is performed by means of a thermal head which is electronically controlled assuring a homogeneous and completely adjustable heat distribution.

Another main feature is the connection of the head to the circuit of compressed air which allows the double ventilation of the capsule during the smoothing phase thus optimizing the process.
