CM 500 R ERGON - Combined machines up to 50 ppm
The combined packers from the CM R range group in a single system the functions of a wrap-around case packer, a tray packer and a shrink wrapper. Therefore, they are the ideal solution to pack a wide range of containers in various types of packs (film only; cardboard pad+film; tray+film; tray only and wrap-around boxes) and to make frequent switches from one product to another and from one format to another.
This series of packers is capable of reaching production speeds up to 80 packs per minute, depending on the machine model, the product type and the selected formats. The pack collations can vary according to the container shape and size; in general, the most requested collations are: 2x3, 3x4 and 4x6 for wrap-around cases and 4x3 and 6x4 for tray + film packs.
The combined machines from the CM R range are equipped with the innovative revolving quick-format changeover system which consists of two rotary modules: the first positioned in the cardboard/loose product advance area and the second positioned in the area of box/tray formation and loose product flow.
The two rotary modules are supplied with double equipment: that required for working in film only and that for the packaging in tray or wrap-around cases.

1At the infeed conveyor of the machine, a motorized system of oscillating guides correctly channels the loose containers towards the pack formation area.
2The Easy-Load system automatically loads the cardboard blanks into the machine cardboard magazine. A corrugated cardboard blank is picked from the cardboard magazine through a cam-controlled picker with new-generation suction cups, moves along the cardboard climb and is positioned below the incoming group of products with short side leading (wrap-around box) or long side leading (tray). The cardboard/ tray packer operates continuously with wrap-around system.
3In the pack formation area, containers are grouped continuously in the selected format through electronically synchronized pins.
4The module for the advance of the cardboard blanks or loose product is supplied with double equipment (MODULE 1):
- SIDE (A): motorized belt equipped with fingers and side guides for the case formation
- SIDE (B): motorized belt for the transport of loose products or products in pad/tray
5The module of the former is supplied with double equipment (MODULE 2):
- SIDE (A): motorized conveyor equipped with fingers and side guides that fold and wrap the cardboard blank around the products. The flap-folding devices fold first the side flaps and then the lower/upper flaps, both of the front and rear side. A gun sprays a thin layer of hot melt glue on the flaps to ensure excellent pack resistance. At the machine outfeed, specific fixed guides press the walls of the box that has just been realized.
- SIDE (B): motorized belt for the transport of loose products or products on pad.
The rotation of the two modules by 180 degrees enables to obtain the pack combinations shown in the picture.
6In case of packaging in case/tray with shrink film, the unwinding of the film reels, positioned in the lower part of the machine, is controlled by a brushless motor, that ensures the precise and constant film tensioning. Before the pack enters the shrink tunnel, the film is cut by a knife equipped with motorized blade, wrapped around the group of containers and overlapped on the pack bottom.
