Lanfranchi has introduced a new update available for all its unscrambler models to respond to the continuous lightening of PET bottles. Lightweight PET bottles bounce around more and are harder to control.
But now, thanks to the Vacuum Sliding Plate system, the Lanfranchi Unscrambler is ready to compensate for this instability by drastically reducing bottle jumps and keeping the speed of the unscrambler high.
The vacuum sliding plate quickly stabilizes a bottle inside the cradle and keeps the bottle in the ideal position for the following step of controlled drop through the funnel ending with the bottle standing up and ready to exit the unscrambler.
So, among the positive aspects of this upgrade is the increase in efficiency in the reordering process with more bottles correctly positioned within the funnels during rotation.
Our customers require a solution for stocking lightweight bottles, such as PET, PE, PP or HDPE, so Lanfranchi has designed a new system to reduce the load inside the silo. This new system can also be installed on existing silos such as FAST silo, Ultra-Clean, etc. and purchased as an upgrade.
The main concept of this application is to distribute and reduce the pressure of the bottles placed in the upper part of the silo compared to those in the lower part. It consists of a continuous series of inclined panels that are inserted inside the silo, dividing it into areas, the first effect of which is a uniform distribution of loads over the entire length of the silos (horizontal loads during the emptying operation).
Another important result is that these continuous baffles also reduce vertical loads. Thanks to their inclination, the load of bottles placed at the top does not have an impact on the load of bottles placed at the bottom.
With the Aspirated Star-wheel your bottles will not suffer a single scratch and you will no longer have to replace stars at every format change and have excessive encumbrance. If the range of bottles to be processed is very wide, the Vacuum Star-wheel is equipped with interchangeable and removable inserts. In most cases, two sets are more than sufficient to cover the entire range of bottles. The inserts are easily and manually applied. The vacuum itself and a mechanical interface, calculated at the design stage, keep these inserts in their positions.
How the Vacuum Star-wheel is being installed:
The upgrade consists of a pre-assembled unit that will allow easy installation on site. The old machine substructure will be dismantled on site (except for the lexan guards, which will be reused) and then the new pre-assembled unit will be installed, which will consist of the new substructure, the vacuum chamber, the vacuum star-wheel and then the fan complete with motor.
Thanks to Click Clack the Lanfranchi Unscrambler becomes even more flexible, practical and user-friendly. You can change the format of your bottles with a simple click!
MAIN ADVANTAGES:
It is not necessary to dismount parts: thanks to a hidden spring, you just need to raise or lower the lifter’s block with a click.
Thanks to the removal of the polyethylene blocks to be dismounted and reassembled, with a simple click-clack on the lifters it is possible to significantly reduce the operational process needed for each changeover.
By using Click Clack Lifters, it is possible to eliminate stock of pieces needed for the changeover.
The parts needed for the changeover leave the facility already installed on the machine and tested, reducing the possibility of errors due to the mixing of the parts.
System for reduction of compressed air consumption in unscramblers.
The new BFS system has the function of removing bottles in excess and misplaced inside the puckets.
The system is composed of fans ( from 2 to 8, depending on the model of the machine), which have an installed power of 0.85 Kw.
The main advantages of the BFS are:
The system can be used, on request, with the integration of filters, to create a slight overpressure of clean air, inside the machine.
The system is available to upgrade existing lines, even those not supplied by Lanfranchi.
This Upgrade can be installed on both table-top and air conveyor systems.
The micromotor used to move the side guides consists of a compact unit that includes:
The motor powers a threaded rod that is connected to the side guide.
The length of the rod can be varied according to need, so this system is truly ‘infinity’.
These motors were tested at Lanfranchi for months, having them changed thousands of times a day to check their reliability, and the component worked flawlessly.
The micromotor that controls the vertical movement is attached to the C-channel and to the bracket on which the other micromotor is mounted.
Since the lower micromotor must move up and down, the bracket is connected to a linear guide fixed to the side of the C-channel.
The system is available to upgrade existing lines, even those not supplied by Lanfranchi.
With LACO, the changeover is quick.
The LACO concept is based on the very simple ‘release, slide and lock-in’ formula in which the operator moves the lower part of the funnel into mechanical positions that are clearly marked; the cradle requires only a tool-free replacement of a separator according to bottle size. In the faster models of unscramblers with separators, the standard use of the vacuum star-wheel and the LACO design may eliminate the need to replace separators.
The format change operation is easily taken care of by a single unskilled operator and according to the machine model and bottle characteristics can range from 5 minutes up to a maximum of 30 minutes.
Laco funnels, with predetermined manual adjustment, process all sizes of bottles and do not require changing parts. Adjustment of the new Laco funnel is done simply by moving the knob to the position indicated for the bottle format to be processed, thus avoiding operator errors.
