   B: Mechanical parts

   Transportation institution: B&M AC motor 370w (with deceleration by BBM), inverter speed control

   Conveyor: industrial nylon chain plate conveyor

   Mainframe transportation institution: B&M AC motor 1.5Kw (with deceleration by BBM)

   Sub bottle institution: industrial worm sub bottle institution

   Into bottle institution: with worm sub bottle institution and starwheel position feeding institution to ensure the accuracy and stability of loading

   Position institution: Mechanical pre-location, using the camwheel institution to planish the bottle for label positioning

   Labeling institution: Containers are picked up by rotary wheel, labeling during the rotation.

   Supply label institution: Sunswell high speed servo OPP label supply system (drive by servo-motor)

   Pressing label institution: Arc brush unit

   Guided bottle institution: adjust by double coordinate section guide rail

   Glue supply system: Sunswell hotmelt glue supply system (German SEIMEC control system) ensures the accuracy and uniformity of gluing

    

2. Safety part of the machine

   Safety protection: In order to keep the operator safety, when the machine is running please close the protective doors

   Lack of label alarm: Set an alarm to remind the operator to change the label when the label will be use out

   Lack of bottle alarm: When lack of the bottle the machine will stop and make an alarm .The machine will restart automatically as soon as the bottles have been put that will facilitate on-line production

   Leak of labeling alarm: To control the quality of labeling

   Pressure testing: When the pressure cannot meet the equipment requirement, the machine will stop to against bad products produce

   Vacuum testing: When the vacuum cannot meet the equipment requirement, the machine will stop to against bad products produce

   Temperature testing: When the temperature cannot meet the equipment requirement, the machine will stop to against bad products produce

    

3. Method of Operation

   The containers are picked up by the infeed starwheel and transferred to the container table. The container rotation begins when they are positioned between container plates and centering bells.

   The speed of the feed roller is adjusted to the required label length for continuous web tension. A standard threading unit ensures optimal film feed. In the cutting unit, the labels are precisely cut while a PLC commandand servo-motor provide an exact cut-off point.

   Two narrow strips of hotmelt glue the labels together, which are applied by a heated glue roller to the leading and trailing label edges. The label with the glue strip on its leading edge is transferred to the container. This glue strip ensures an exact label positioning and a positive bond. As the container is rotated during label transfer, labels are applied tightly. Gluing of the trailing edge ensures proper bonding.

    

   Process: Infeed bottle → pre-position →label cutting → gluing → labeling→label by press out → finish
