What distinguishes us
SIPMA OS 7521 Bale wrapping machine
The SIPMA OS 7521 Bale wrapping machine is fully automated self-loading machine, attached to the tractor. Full automation of the process is provided by an advanced control system which allows pre-programming a wrapping cycle.
Capabilities of the control panel:
- manual, semi-automatic or fully automatic operation of the machine,
- monitoring of the ongoing process of winding (number of wraps counter),
- counting the number of wrapped bales,
- measuring the time of operation [h] with the accuracy of 1 minute,
- counting the achieved performance [ha/h],
- measuring the volume of work on three independent programs (fields). Independent calculation of the number of wrapped bales, working time, achieved performance (this enables us to compare the performance achieved on three different fields),
- programming the number of film layers (depending on the kind of film used, we can program the number of layers, beyond which an alarm sounds),
- setting the machine automatically for transport,
- checking the status of reed sensors (because they are vulnerable to mechanical damage, we are able to rapidly assess their operation efficiency and possibly change a defective sensor without calling for the service)
- checking the sum of wrapped bales since the installation on the wrapper.
The in-line process enables the operation of the machine in the same direction as the round balers (cross the field), ensures fast bale loading and bale wrapping while approaching the next bale thus performing high efficiency.
The damper system allows bales to be gently lowered to the ground and tipped on their end or rolled on their side onto the field, protects them from potential damage during discharge.
Hydraulic film catcher-cutter works automatically after each bale wrapping process, provides a considerable acceleration of the wrapping process and its efficiency.
Universal film dispenser allows the use of 750 and 500 mm wide films. The 750 mm wide film requires only 16 revolutions of the wrapping table to wrap a bale and greatly reduces the wrapping time.
Aluminum, milled film dispenser rollers provide the initial film stretching and appropriate adhesion during the wrapping process.
Adjustable drawbar facilitates bales loading and the machine transport on access roads to the field.
Wide tires provide the opportunity to work in wetlands and peat.
