Aluminum Profile Wrapping Line

ALUMINUM PROFILE WRAPPING LINE

GENERAL DESCRIPTION

1. HYDRAULIC LIFTERS

These are positioned under the skip unloading positions and are designed to automatically maintain the height of the top layer of profiles being lifted out of or into a skip. Standard lifting capacity is 400 kg per unit. It includes photocells, electrical part and all hydraulics.

Max. Lifting stroke: 800 mm

Lifting time: approximately 40 secs

2. SET OF INFEED CONVEYORS TO PROTETIVE MACHINE

Motorized roller conveyor is for loading the profiles into the adhesive application machine, which includes a set of vertical rollers for centering the profiles as they are loaded into the machine.

3. ADHESIVE FILM MACHINE

Newly designed machine designed to attach an adhesive film to top and bottom faces of the profiles smoothly and without creating blisters in the film itself .The machine includes a blade unit for cutting the adhesive tape between one profile and the next profile, without stopping the machine for each cutting cycle. The newly designed blade unit ensures a clean cut with the elimination of any overhanging tape.

4. OUTFEED BELT CONVEYOR

This belt conveyor is designed to automatically transfer profiles out of the adhesive film application machine.Belt material: Anti-wear PVC

5. SET OF 4 CROSS TRANSFER BELTS

These belt conveyors are designed to automatically transfer profiles across from the adhesive film line to the wrapping machine line.

Belt material: Anti-wear PVC

6. LARGE SPIRAL WRAPPING MACHINE

Machine is designed with a compact steel frame. Replacement of wrapping material is carried out quickly and easily (under one minute) using bayonet type quick change holders for rolls of wrapping materials. Profiles are drawn through the machine by a series of rollers which open and close automatically, allowing bundles with different dimensions to pass through automatically without stopping the machine. The wrapping device is composed of a rotor which rotates and holds the roll of wrapping film which is supported by a mandrel with specially designed clutch designed to maintain the tension constant until the roll is finished. Theses rolls are easily and quickly replace in less than one minute. The speed is regulated by means of an electronic inverter controlled through a potentiometer situated on the main control panel.

7. Taping machine

This machine tapes the front and back of the profiles as they are moving through it and does not need to stop. It tapes several spirals (binding coils) to the front and back end of each bundles to prevent the wrapping material from unravelling. It is programmed to tape the profiles according to the speed of the wrapping machine lying before it ,Used mainly when wrapping with paper or nylon which is particularly prone to tearing and unraveling.When wrapping with stretch film ,the machine can be paused and switched to idle mode .

8. OUTFEED ROLLER CONVEYOR WITH AUTOMATIC BUNDLE STACKER

This machine is fitted with a pinch-roller device which is accelerated by an inverter. It carries out the detachment of the finished bundle and then stops in the right position, aligned for the formation of the bundle layers. Automatic device with lifters is for the formation of the bundles. A special pneumatically operated device automatically interlaces a nylon cord between each layer of profile bundles while it is in production to prevent these from sliding over when moved .This machine is continuously fed by the bundles coming from the wrapping machine; it superimposes them layer on the layer producing in this way a bundle of the size chosen by the operated on the main control panel.

9. CROSS TRANSDER CHAIN CONVEYORS

These chain conveyors are designed to cross transfer the stacked bundles onto the next machine after the automatic bundle stacker.

10. SECOND EXIT ROLLER CONVEYOR

When the profiles /sub-bundles need to be stacked and packed manually, the second exit is used to transfer the profiles to the manual packing line; the machine includes a pneumatically operated pantograph used to push the profiles across onto the accumulation belts.

11. BELT CONVEYORS FOR PROFILES CROSS THRANSFER

These conveyors are used to transfer the profiles / sub-bundles across to the manual packing line.They are fitted with sensors at the end of the belts to prevent the profiles from falling off.

12. SET OF LOADING/UNLOADING CHAIN CONVEYORS FOR BUNDLES

These conveyors are used to either load or unload the bundles onto the main chain conveyors leading to the strapping line .

13. BUNDLE STRAPPING

This machine is designed to strap the completed bundles with the wood blocks ( upper, lower and side wood block ) before the shipping. The strapper itself is equipped with a wood blocking device for clamping the upper ,lower and side wood blocks during the strapping operation .

14. MASTER BUNDLE WRAPPER

Sturdy machine ensures the rapid and uniform bundle wrapping. The master packs of profiles are fed into the machine by the intermediate chain conveyor. The bundles is wrapped by means of a single roll of polythene mounted onto a mandrel which rotates on a rotor and guide by special clutches to control the wrapping tension. The rolls of wrapping material can be replaced quickly and easily. The machine is fitted with an electric device which controls if the material has run out or has torn and automatically stops the machine. The wrapping cycle is completely automatic. A specially designed clamp is used to hold the first part of the stretch film for a consecutive wrapping cycle meaning that the re-starting of the machine for each new bundle to be wrapped is completely automatic.

15. SET OF 5 CHAIN CONVEYOR FOR BUNDLE ACCUMLATION
