Lanfranchi offers a variety of conveyor systems that allow us to meet every need and ensure gentle handling of containers.
Lanfranchi is able to transport PET or HDPE bottles at high speeds ensuring high efficiencies. All the components (curves, assemblies, dividers, etc.) have been designed with the aim of maximising the efficiency of the line. The Lanfranchi air conveyor belt is available in three versions:
Over time, Lanfranchi has developed optimised software for the management of flows dedicated to each single container and, more importantly, has created a system called ASC, Automatic Speed Control (patented), whereby the change in fan speed is controlled automatically and differentiated based on the area where the conveyor is operating (blow moulding machine room, connection tunnel, filling room, etc.).
We can confirm that with the ASC system we have succeeded in combining and therefore controlling various factors that affect conveyor speed, such as room temperature, level of ambient humidity and the blower process that can vary over time.
Lanfranchi is also able to precisely detect the positions that container jams can occur in, but especially with JRS (Jamming Resolution System (patented), it is possible to resolve the jam and make container feeding automatically start back up again to the filler.
Lanfranchi can provide various systems for body and neck guide format change:
The Lanfranchi air conveyor belt is characterised by its modern design while also being functional.
The electric conduit is available in various types and integrates perfectly into the main structure. There are numerous accessories that complete the air conveyor belt product. The levels of filtration that can be supplied are three:
Pivot sections make it possible to adjust the infeed height to the fillers or to the labelling machines if the height of the container being processed varies.
The automatic brake is a device used to regulate the flow of bottles along the conveyor. It can be either single or double.
The single brake is installed before the intermediate dump gate. By opening or closing the plates you give time to the dump gate to open or close as needed. The double brake is installed before the divider-combiner. By opening or closing the plates it prevents the containers from flowing towards the divider-combiner while the latter is still moving. Both systems form trains of containers to create a smoother flow of movement along the line. The motors are controlled through the use of frequency variators that can be installed directly on the fan motor or inside the electrical panel. Numerous container speed sonar sensors linked together with profibus network make it possible to monitor line operation in real time.
Lanfranchi pneumatic conveyor systems are robust and provide efficient results in handling empty plastic containers of different types: from PP to HDPE. Pneumatic conveyor systems are made of steel but the PVC tube version is also available which requires low maintenance.
The Lanfranchi range of products for the handling of empty plastic containers also includes conveyor belts with suction and without suction. The main advantages of Lanfranchi conveyor belts are:
The belt vacuum units are completed with a wide range of accessories with which it is possible, for example, to obtain divisions from one to several rows or to increase the cleanliness features of the conveyor. Also for this type of conveyor, automation has been greatly refined so that, for example, the vacuum levels can be set and checked according to the different sizes to be processed. Both the conveyor belt frame and the vacuum chamber underneath are made of stainless steel.
Various types of conveyor belt covering are available: from the upper dust cover to a complete casing.
The suction fan is housed inside soundproofed casing. By using the butterfly valves inserted in the connections between vacuum chamber and conveyor belt, zones with different vacuum levels can be defined, such as in the collection tracts, for example. All the components of the table-top conveyor belts (alongside conveyor sections, the bends and the separators) are also available for the vacuum conveyor belts.
The chains of the vacuum conveyor belt are perforated according to the type of container being handled.
Our bulk conveyors have been developed in order to reach the excellence in the handling of the containers and are destined to handling of the containers before the unscrambler.
The numerous customisations provide, for example, the possibility of using plastic nets or rubberised belts.
The hoppers can be increased and motorised to create micro accumulations of different sizes directly on the line. A dirt protection cover can be installed on request. Automation has also been optimised for this type of conveyor. For many people, a bulk conveyor belt is just a coarse conveyor. For Lanfranchi is a fundamental element of the lines of its Customers.
The structure of the conveyor belts and the possibility of combining covers, make Lanfranchi belts particularly “clean”. Even the hoppers, which are designed to optimise container handling, can be covered. The edges of the conveyor can be opened for easy access inside the conveyor belt and thereby simplify cleaning and special maintenance activities.
Thanks to the elevator or lowerator, the containers are conveyed with considerable changes in height, reducing the footprint to a minimum. According to the physical and morphological nature of the containers, Lanfranchi offers a broad range of elevators and lowerators:
For every type of application, thanks to their specialised multi-year experience the Lanfranchi team and offer the best solution.
