MSW is the series of PRASMATIC medium-speed automatic shrink film wrapping machines mainly dedicated to the food and beverage industries, where the primary requirement of high productivity is combined with the request for high reliability and flexibility.
The design of this new machine series has made use of the latest technology, using electrical axes with brushless motors for managing movements. The easy programming of the parameters and the simple user interface make the MSW series machines extremely versatile. Product separation and pack creation units were studied following the principle of optimising the processing cycle and format change times. Proper film feeding is guaranteed by controlling the unwinding and winding speeds with brushless motors and by using a cold film cutting system, through a rotating blade. The new concept and the ergonomic design of the MSW series are born from the experience of PRASMATIC, which allowed creating an extremely easy to use series of machines, at the same time guaranteeing minimum maintenance costs thanks to self-supporting structure entirely laser cut, with large sliding doors that allow a total vision of moving mechanical parts.
This device can be set up at the machine infeed to feed and distribute single products or product packages coming from a single-row belt into more than one row. The divider comes in various models and configurations based on line production speed and product type, it is particularly suitable for products with an irregular shape.
The press separation system is suitable for medium/low speed. The product used to create the format is separated by the combined action of the press and the bottom conveyor belt. This solution ensures the maximum simplicity in terms of function and adjustment during the format change operations.
Electronic product separation
Continuous separation system with electronic control for medium and high speed. Product separation is carried out through a double pair of teeth, with infeed between the products from the bottom. It is very easy to make adjustments during format changes to change the product size.
RETRACTABLE COLLATING PLATE
This solution offers high flexibility for the range of formats that can be produced, it also offers an excellent compromise when switching from tray packaging to packs with heat-shrink film only, and vice versa. The pneumatically-actuated surface offers the possibility of producing trays with high edges, it is particularly suited for the production of full height trays.
Various film reel positioning solutions are available, the ergonomics are particularly well-designed. Better access for format change operations and reel sealing means excellent man-machine interaction. The external reels option also offers automatic reel-change. AUTOMATIC REEL CHANGE The system seals and cuts the film in a fully-automated fashion without any operator intervention, this option makes it possible to continue without stopping film unwinding and the production cycle. The reel configuration is set up by the operator, through simple manual procedures.
REMOVABLE FILM UNIT
The system offers easy access the film unit, for quick and efficient maintenance. This application is particularly suited for liquid product sectors, such as dairy and beverage, where the primary packaging may break, possibly soiling the film
AUTOMATIC FORMAT CHANGE
For models with automatic format change, switching to the new format is carried out electronically through brushless motors, in most cases there is no need for tools or for the machine to be manned by the operator. Format change operations are carried out simply from the operator panel.
The role of the stacker unit is to stack two or more layers of product, the unit can be configured differently based on the type of product or the packaging solution. Thanks to its reduced dimensions or its mechanism, it can be installed without increasing the footprint of the base machine
