Rotary machine hot glue 6000-30000 bph
Paper or pre-cut OPP
Labelling machine type MEGA HOT is fully automatic and has been designed for the application of wrap-around paper and plastic pre-cut labels on cylindrical container and/or shaped.
Model MEGA HOT features platforms that may be driven by pulleys, toothed belts, cams, electronic cams or brushless motors. MEGA HOT installs a hot melt applicator to deliver adhesive to patented controlled fiberization guns onto the container first and then a slot gun integrated in the labelling magazine applies a vertical strip of adhesive on the trailing edge of the label for all its height sealing the label end. Hot glue unit with nozzles aggregate has several advantages respect to the glue roll hot melt type, such as the absence of adhesive carbonisation, a minimum down time for cleaning and maintenance, minimization of adhesive waste.

The automatic mechanical orientation is applicable to containers with a cylindrical cross section. The first orientation device is the simplest and the cheapest. The orientation takes place on the labeller infeed star.
A mechanical arrangement (a spring loaded lever) hunts and catches the container (which can be only cylindrical), by a spotting notch or bar moulded into the lower side wall area.
The bottle held in the required position is transferred on to the carousel plates. The degree of accuracy which is possible to have using this mechanical device is good but not the best possible.
The same device is used to orientate a cylindrical container according to its handle where the handle subsitute the spotting notch for feature. A second type of orientation takes place on each carousel plates. In this case the bottle centring platform is made up of two sections: an inner rotating section and a fixed outer section. The container, always cylindrical, needs to have a spotting bar on its bottom. The bottle goes onto the plate (which at this stage, has the two sections at the same level) and, once that it is clamped firmly against the fixed auter plate section by means of pressure from the descending centring bell, the rotating inner plate section is held down via cam operated stirrup, enabling the spring loaded hunting lever to touch the bottle bottom. Then, by spinning the bottle around 360°, the lever catches the spotting bar. When the lever is into the spotting bar il will drag the bottle in the required position, ready to receive its labels.
In few cases the cylindrical container have letters, scales, figures in relief but no spotting bar or notch. NUOVA BRB has an orientation device solutions also for these special packages.
Through a mechanical sensor and a system of levers which increases the sensor sensitivity the device is able to detect a 3/10 of millimetre relief.
Moreover by positioning the lever on the machine carousel dish and by installing another very simple mechanical device, this system is not sensitive to containers eccentricity.
Opto electronic orientation
This type of orientation device is more sophisticated than the mechanical one and it is designed for medium and high output rate and orientation feature different from that previously exposed. The orientation through luminescence sensors can sense marks which can be a color dot (like on champagne capsules with product name printed vertically) or the seam of a can or any other significative color texture. These marks are detected by a fiber optic sensor which can “see” the mark from the type of light which, shooted by the fiber optic, hit by the container, goes back to the photo cell. The orientation takes place on each carousel plates.The plates, which can be driven by clutch brakes system, stepper motors, or brushless, rotate until the photocell detect the mark and interrupt container rotation. At that point plates are ready to handle the container in the position required for the label applications.
By using another type of luminescence photo cell or camera it is possible to detect also ribs on plastic containers (ribs are made especially on containers for aesthetic purposes or for increasing the grip of the surface which has to be grab by the consumers).
BRB Globus is able to offer to its customers a long and successful experience in self-adhesive labelling onto unstable containers.For unstable container we mean these containers which, due to a very small bottom base or due to a very conical shape, need a puck or godet in order to be able to be handled into different machines of a bottling line.The container is put into the puck at the beginning of the streaming line and de-puck at the end.The use of those pucks is quite common in the cosmetic and pharmaceutical industry,sometimes also in food sector.
The container arrives into the labelling machine in one of those pucks and here at BRB Globus we have a long experience in the handling of pucks in the labeller and also in designing them according to the label the customer wants to apply.
Excise stamp application (tax label L, U shape)
BRB Globus rotary labelling machines can apply excise stamp U and L shaped with cold glue and tamper evident or guarantee L shaped self-adhesive labels.
By means of an original and highly reliable outfeed star, the excise stamp, previously applied on the bottle neck in vertical position,is taken down to the cap (in case of excise stamp or security L, or to the cap and the other side of the neck (in case of excise stamp U shaped).
