New line fills personal care products
Marchesini supplied ICR with a complete shampoo line, from filling in bottles to packaging in cases, which is capable of processing 120 bottles per minute. The line consists of the following machines:
- a mechanical positioner that places the bottles in pucks
- a bottle filler ML661
- a Neri labeller RA800 2T
- a top loading casepacker MCV850
The product processed is a plastic bottle with two different sizes - 40 mL and 75 mL – with screw-on and flip top cap. The bottle is delivered by the mechanical feeder in pucks to the ML661 filling machine, which uses a special filling unit that adapts to the product’s viscosity. First and foremost, the product-feeding hopper is controlled by a thermostat so that the liquid is kept at the correct temperature should the machine stop. Because the filling process involves a rather tricky liquid to handle, in view of its high degree of viscosity, a number of special solutions have been integrated in order to guarantee high performance, such as: larger pipes, Ketron Peek valves rather than ceramic valves, and batching nozzles with air blowing cut-off valves to avoid soiling the bottle during filling.
As for the capping phase, the machine model ML661 initially screws the cap on to a preliminary 1 mm from the end of the full stroke. On the outlet, a unit with 3 screwing heads, each equipped with brushless motor, subsequently screws the cap on to the correct tightening torque. The use of brushless motors means that any anomalies in reaching the correct tightening torque can be controlled during the screwing phase.
Why did Marchesini devise a system with two capping stations? To be able to position the cap correctly because it has to be perfectly and exactly aligned with the lateral face of the bottle, and also to reach the end-of-stroke gently. Because these products are cosmetics, they have to be handled very carefully.
Downstream from the filling machine there is a Neri labelling machine RA800, on which the PharmaSpec product inspection system is installed. The PharmaSpec has 3 cameras: the first checks the arrival position and turns the bottle, if necessary, before the labels are applied; the second and third are positioned further forward and make sure the label has been printed and check the finished result of the labelled bottle. Furthermore, a de-ionization system eliminates any static electricity possibly generated during unwinding on the label reel.
The bottles are then packaged directly in cases by means of the Marchesini Top Loading Casepacker MCV850, equipped with robotic infeed, which is extremely flexible yet very reliable. The bottles reach a Robocombi system that picks them up and places them on a transfer plate: once the plate is full, it traverses towards the pick-up head that picks up the whole layer of bottles and places it directly in the case. During the traversing phase, a second empty plate moves towards the Robocombi system, thus guaranteeing the full output of 120 bottles per minute. The empty pucks are finally sent back towards the head of the machine. The supply is completed by an in-between sheet inserter. 3 dividing sheets are placed between the layers to protect the bottles inside the case.
All in all the new line is an impressively hi-tech solution capable of guaranteeing total protection and safeguard of the package throughout the whole process, step-by-step, in addition to precision and reliability in the filling, labelling and casepacking phases.
