Tosa 150 Rotating Ring Stretch Wrapping Machine
The Tosa 150 Rotating Ring Stretch Wrapping Machine is a high-performance solution designed for maximum capacity and efficiency in pallet wrapping. With a ring rotation speed of 65 rpm, it can handle up to 150 pallets per hour and uses film rolls up to 750mm wide.
Features include a motorised pantograph top presser, automatic vertical corner post application, and a double brushless motor pre-stretch system, offering pre-stretch ratios from 0 to 400%. The machine is built to reduce maintenance costs with lubrication-free bearings and a film consumption-reducing film roping system.
Optional features include an automatic stretch film roll change system, top sheet dispensing units, and a Smart Wrapping Technology system for optimising film distribution and tracking data.
The Pallet Stretch Wrapper Model TOSA 150 with rotating ring is positioned in the top segment of the market, being able to respond to the highest capacity demands thanks to the ring rotation speed of 65 rpm and the possibility to use film rolls 500 mm or 750 mm wide. The machine has been designed specifically to minimize the maintenance costs and the film consumption.
Automatic powered pre-stretch with ratio up to 400%.
• Sealing unit with contrast-bar for welding the film without any
contact with the product.
• Inverters and Encoders for maximum precision for movement
control.
• Operator panel 10” colour with graphical interface for easy
use and understanding:
– manual movement operations;
– production data in real time (cycle times, film consumption);
– graphic visualization of machine faults and trouble-shooting
designed to make it easier and quicker for the operator’s
intervention.
• It is possible to prepare wrapping programs, dedicated
to each product format with variable parameters such as
film tension, wrapping cycle type, spiral pitch overlap, film
pre-stretch and position of film roping (option).
The use of a film roll 750 mm wide allows not only to reduce
the number of film wraps needed for completing the wrapping
cycle, but also to cover a wider surface of the product with each
wrap, increasing the stability of the load.
• Film roping system functions by reducing the film width
from the bottom and the top by means of two independent
compression wheels, driven by brushless motors with an
encoder, which allows the setting of the film band width, in
any position on the pallet with precision.
• The pallet lifter allows to also wrap the base of the pallet with
the film rope.
• Up-down movement of the ring by means of toothed belts,
completely maintenance and lubrication free, and designed in
a Fail Safe configuration, with double belts for each machine
column.
• Gearless direct motorization of the ring lifting system, with no
need for maintenance.
• Use of lubrication free guiding wheels and of special guide
ways for the ring carriage, requiring lubrication only on a
greatly reduced frequency and only in case of operating in
highly dusty environments.
• Lubrication free bearings are used on the machine.
Optional TOSA 150
PRE-STRETCH WITH DOUBLE
BRUSHLESS MOTORIZATION
The two pre-stretch rollers are independently driven by two state-of-the- art brushless motors. Allowing the possibility to program wrapping cycles with a pre stretch ratio variable from 0 to 400%. Optimizing film distribution on the pallet during all wrapping phases
AUTOMATIC STRETCH FILM ROLL
CHANGE SYSTEM
The automatic stretch film roll change
system, model TOSA 801, allows the
replacement of the exhausted film-roll in
30 seconds with no operator intervention.
Patented in Europe and America.
TOP SHEET DISPENSING UNITS
FOR DUST PROOF PROTECTION
The systems for the application of a plastic top sheet to protect the pallet load can be supplied also with two film-roll positions, which can be automatically selected to increase the film autonomy reducing the machine stops for film-roll changeover. Available also with an automatic top sheet film roll changing system, eliminating machine stops required to replace the exhausted film-rolls.
MOTORIZED PANTOGRAPH
TYPE TOP PRESSER
This motorized device ensures maximum flexibility of use, reduction of overall height of the equipment and optimization of energy consumptions where a top presser is required. Thanks to the use of lubrication free bearings, this unit does not need any maintenance.
