DESCRIPTION OF ROLL-FED LABELLING MACHINE
► Machine Stardard Features
The standard infeed and discharge conveyor configuration is in-line.
► Base Frame and General Structure
The support frame is made of welded strong iron steel profiles and is equipped with height adjustable feet. Anti-vibration and noise absorption principles have been applied everywhere.
The top surface is a heavy-machined carbon steel plate, covered with Aisi 304 stainless steel metal sheet.
Inspection is possible through side doors and frame side skirting clad with Aisi 304 stainless steel plate.
Castings and carbon steel parts are treated against corrosion. The treatment operations are: sanding, chemical cleaning process and epoxy painting (multi-layer process).
Machine standard colour is RAL 7038. Other colours are on request.
Our strength: The general structure of the machine has been designed to work 24 hours a day even in a wet environment; a large use of corrosion resistant materials, such as stainless steel, non-ferrous alloys, plastic, etc. is made.
► Main carousel
The machine head height can be electronically regulated from the operator panel.
Container head gripper jacks, controlled by a mechanical cam, have a triple parallel stem structure, with mechanical stroke compensation in the standard version, but a pneumatic compensation system for a fine regulation can be provided on request.
Self-centring type container platforms to allow a perfect positioning of the bottle; their surface is coated with friction improving material, to avoid container slippage during machine operation. Spoked type design container table, for easy debris removal.
Platforms rotation transmitted by belt (R version to handle round container).
► Safety guards
Safety guards are present along the whole base frame perimeter.
Guards are made with transparent material windows. Also the guards on the lower part of the base frame can be transparent on request) to allow a complete visibility of the machine parts (Visual Maintenance).
Openable doors are fitted with safety type micro-switches.
► Roll-fed labelling station
The standard labelling aggregate is equipped with two reel stand supports. A film tension control system operates on each reel stand.
During working process, the film vertical position is controlled and continuously adjusted by an automatic web tracking system before arriving to the feeding roller and the cutting drum.
The film feeding roller is driven by an independent servo motor that corrects the feeding speed according to the actual detection of a spotting mark or a reference on the film and according to the machine production speed via encoder.
The label is cut by the mechanical interference between the static blade and the rotary blade; regulation and fine tuning is very easy. Exact tuning is necessary to have long life blades.
Cut labels are transferred by an aluminium vacuum drum.
NO GRIPPERS ARE USED!
Hot Melt glue is distributed on leading and trailing edges by a high precision stainless steel cylindrical glue roller; thin gravures are machined on the roller to have a very low glue consumption.
Vertical and horizontal labelling aggregate positioning is adjustable to allow different container diameters and different label heights.
Drive is given to label station by linear gear to gear transmission and an overload protection system (electrically interlocked synchronous clutch) protects mechanical parts from label jams.
Our strength:
· No grippers to transfer cut labels: this implies a higher speed, less mechanical parts, less wearing, a simple and easy cleaning and thus less costs for maintenance.
· No slippage between label and transfer vacuum drum: the different label material parameters and the transfer vacuum drum surface quality do not affect the machine efficiency. The labelling process is thus less critical.
► Machine drive
Main gear box is of crown-screw worm type and oil bath lubricated.
Machine speed follows the container infeed and discharge flow; the main electric motor is controlled through inverter.
In order to improve precision and to reduce noise the machine is equipped with linear gear system transmission, with gear wheels made of C40 steel and Zellamid, with alternate disposition.
Grease lubrication is centralised, with grouped and easy to reach feeding nipples.
Feed screw and starwheels transmission systems are complete with safety electro-mechanical clutch devices to shut the machine down in case of container jamming.
► Infeed and discharge conveyors
Open section conveyor channel complete with drip pan, made in Aisi 304 stainless steel, with wear-proof plastic rollers and sliding profiles.
Tabletop type conveyor belt, Aisi 304 stainless steel (or Delrin) made.
Bottles are guided by stainless steel plus plastic contact profiles side guard-rails, adjustable both side-wise and vertically.
The infeed gate lock device can be manually or automatically operated.
► Machine control system
The machine is delivered with complete electric and pneumatic plants, ready to be connected to the main factory plants.
Pneumatic plant is complete with pressure regulation unit and air filter.
The stainless steel main electrical cabinet, waterproof type, is integrated in the machine structure.
All machine controls and status/signal lights are centralised together with a multi-function operator interface display screen on a single operator panel, complete with removable push-button station (emergency stop + pulse motion buttons).
Push buttons (mushroom head type) for emergency machine shut down are available at strategic locations, easily accessible to the operator.
A PLC unit, supervises the machine automatic operations.
Machine main motor controlled through inverter, plus set of sensors mounted on the conveyor, for an automatic-continuous speed variation, according to containers flow.
Machine infeed automatic closure starwheel, in case of containers build-back at discharge side.
All electric and pneumatic power and control circuits are built in accordance with the latest applicable international standards (CE Standard).
► Something more
-Easy and quick maintenance and lubrication thanks to the high quality of components and materials used.
-Machine designed in order to have the maximum accessibility for cleaning and debris removal purposes.
-Quick bottle/label size changeovers.
-Colour or customized coded changeover parts and accessories for an easy and quick identification.
