Automatic rotary labeling machine

AUTOMATIC ROTARY LABELING MACHINE

Automatic rotary 9-heads labeling machine suitable to handle cylindrical or shaped containers in glass, metal or plastic by SELF-ADHESIVE system with:

  • Body Label
  • Back Label
  • Regional mark.

Required output: 6.000 BPH on a cylindrical bottle format.

THE MACHINE CONSISTS OF:

Supporting structure or machine table, made out of sturdy metallic structure in electrically welded steel, grinded surface and also completely coated by sheet in GLAZED stainless steel  AISI 304 with lateral access doors for maintenance

Total safety guarding as per EC standard rules in one only stainless steel structure incorporated together with the machine table and with its access doors for the maintenance in Plexiglas controlled by micro-switches for security.

Machine complete with passing conveyor belt boxed structure with standard length of mm. 2500 without motorization.

Automatic speed variation by inverter depending on bottles flow.        

The main transmission of mechanical components by means of pinions made of steel and Zellamid to reduce wear and noise of contacting parts without the use of special lubricants, and maintenance.

Lower mid carrousel with container-holding and bottom self-centering platforms made out of steel and anti-slipping rubber for easy substitution and driven by programmed cam and tooth sectors with lubrication by grease.

Upper mid carrousel with cap push jacks in reloaded nylon with same self-centering shaped as the container cap, driven by programmed cam and container height compensation ± 10 mm.

Infeed locking lever with automatic devices of too empty at the infeed and too full at the outfeed with machine stop in case of containers jam-up.                                                                                                    

Manual adjustment of the height of the jacks-carrying upper carrousel by hand wheel on the top.

Principal controls panel board complete with jogger for format change-over operations and light indicator for the main failures.

Introduction worm-screw, infeed/outfeed starwheel s protected by safety microswitches which stop the machine in case of container jam-up.

Labeling stations with sensor of stop paper with self-remembering function.

Labeling station with control panel with digital potentiometer for delicate adjustment of the speed of paper output and delaying paper output.

Self-adhesive labeling stations of our own construction placed on articulated slide for vertical adjustment depending on the label application height and for horizontal adjustment depending on the container diameter to be handled with millimetric position indicators for the format position detection.    

Label wiping by means of nylon brushes or rollers in silicon rubber fitted on a support for fast uncoupling with other wiping for supplementary formats.

Machine provided with equipment to handle No. 1 cylindrical bottle format made out of infeed wormscrew, in-/outfeed starwheel and mid counterstarwheel.

The machine is equipped with a mechanism for labels smoothing consisting of brushes and sponge rollers for working with the basic format of self-adhesive labels.

Inclination adjustments of the self-adhesive head.

3 Table supports for the self-adhesive station with adjustment slide on two axles with numerical visualizers, plus the third one virtual.                                                                     

1 self-adhesive head

Paper transfer with stepmotor for paper outfeed and empty film recovery.

Self-adhesive labeling station speed variation automatically synchronized with the machine.

Photocell for paper stop automatic self-regulation for the read-out of the different label colors.

Photocell of presence of the container.

Controls panel board fitted on the head.

Adjustable articulated labels-detacher.

Max. height of the paper passage 200 mm.

Max. length of the label 250 mm.

Min/max. container’s diameter 40 – 120 mm

Min/max. container’s height 50 – 350 mm

Smoothing star for regional mark.

Set of 9 centering container-holding platforms for cylindrical container.
