SIPMA OS 7521 MIRA bale wrapper is fully automated selfloading machine, attached to the tractor. Full automation of the process is provided by an advanced control system which allows pre-programming a wrapping cycle.
- „Side-back” technological system allows working in a direction perpendicular or parallel to the direction of the press work (across a field), ensures fast loading of bales, wrapping with foil during the drive until the next bale and high efficiency.
- Universal foil film feeder allows the use of 0.50 and 0.75 m wide films.
- Aluminium milled foil film feeder rollers ensure the initial foil stretching, tightness and proper adhesion during the wrapping process.
- Bale elevator allows for putting bales on their bottom or rolling them on their side surface into the field and also protects the wrapped bale from possible damage during unloading.
- Hydraulic film catcher-cutter works automatically after each bale wrapping process. It provides a considerable acceleration of the wrapping process and its efficiency.
- Wide tyres provide the opportunity to work on wetlands and peat fields.
- Autonomous hydraulic power system (additional equipment):
- separates the hydraulic system of the wrapper from the hydraulic system of the cooperating tractor;
- ensures constant and optimal demand of oil supplying the hydraulic block of the wrapper;
- maintains a constant level of oil purity in the system.
- Advanced hydraulic block provides lower flow resistance in the hydraulic system and gives more control possibilities thanks to the option of setting the speed of all working elements of the wrapper.
- Hydraulic system with Load-Sensing function (additional equipment) contributes to the reduction of fuel consumption and extends the service life of the tractor’s hydraulic pump.
- Improvement the work culture of the hydraulic system through the double reduction of average work pressure and the reduction of power consumption.
- Sensor on the loading arm enables automatic initiation of the wrapping process.
- Drive motor brake makes impossible to move the table during the drive.
- Electronic control ensures fully automatic operation of the machine and control of all the parameters of its operation.
- Functions of the electronic controller:
- manual or fully automatic operation of the wrapper;
- graphic visualization of current wrapping process;
- counting the number of wrapped bales;
- programming the number of foil layers (depending on the kind of film used), when reached, the machine passages automatically to next work stage;
- displaying the status of sensors (evaluation of efficiency or inefficiency of their operation) allows to replace damaged sensor, without the need to call the service;
- displaying the sum of wrapped bales since the installation of the electronic control on the wrapper;
- automatic machine setting for work and transport;
- large LCD graphic display showing the actual work parameters;
- smooth adjustment of rotation speed and lifting and lowering of the wrapping table;
- smooth regulation of the speed of lifting and lowering of the loading arm;
- number of table turns can be corrected without interrupting the wrapping process;
- table rotation speed can be corrected without interrupting the wrapping process;
- possibility of pausing the automatic table wrapping mode and resuming it at the storage location;
- foil feeding control - an additional sensor of foil stops the bale wrapping process in case of foil breaks or finishes;
- controling the condition of the oil filter contamination;
- editing all parameters of the automatic mode;
- foreign language support.
