System and method for storage and temporary installation of secondary flooring surface
Systems and methods of rolling and unrolling secondary flooring surfaces, such as tall pile polyethylene turf, are provided. The system includes a drive system that allows for the conversion of a primary surface into a secondary flooring surface in a relatively short period of time. The drive system includes core adjustable speed drive units for controlling the speed and torque of the motors that drive the core, as well as roller adjustable speed drive units for controlling the speed of the front roller. The core adjustable speed drive units control the torque of the core motors during roll up and control the speed of the core motors during roll out.
1. A conversion system for installing a secondary flooring surface over a primary flooring surface, comprising:
a core for storing the secondary flooring surface when not in use, wherein the core is driven by at least one core motor and the at least one core motor is controlled by a core drive unit;
a first roller for supporting the secondary flooring surface on the core and guiding the secondary flooring surface on and off the core, wherein the first roller is free spinning;
a second roller for supporting the secondary flooring surface on the core and guiding the secondary flooring surface on and off the core, wherein the second roller is driven by at least one roller motor and the at least one roller motor is controlled by a roller drive unit,
wherein the roller drive unit controls a speed of the at least one roller motor.
2. The conversion system of claim 1 , wherein the core motor drive unit controls a torque of the at least one core motor while the secondary flooring surface is rolling onto the core and the core motor drive unit controls a speed of the at least one core motor while the secondary flooring surface is rolling off of the core.
3. The system of claim 1 , further comprising a frame for supporting the core and the secondary flooring surface, wherein the frame moves vertically along a pair of end shafts as the secondary flooring surface rolls on or off the core.
4. The system of claim 3 , further comprising a transducer that determines the relative position of the core by determining the relative position of the frame.
5. The system of claim 3 , further comprising a hydraulic lift connected to the frame that assists with the vertical movement of the frame supporting the core.
6. The system of claim 1 , wherein at least part of the conversion system is located in a pit.
7. The system of claim 1 , wherein at least part of the conversion system is located in a partial pit.
8. The system of claim 1 , wherein at least part of the conversion system is a Mezzanine mounted system.
9. The system of claim 1 , wherein at least part of the conversion system is a surface mounted system.
10. The system of claim 1 , further comprising a winch and cable system that assists with the installation of the secondary flooring surface over the primary flooring surface.
11. The system of claim 1 , wherein the core is in a fixed location relative to the primary flooring surface.
12. A system for installing a secondary flooring surface, comprising:
a core for storing the secondary flooring surface when not in use, wherein the core is driven by at least one core motor and the at least one core motor is controlled by a core motor drive unit;
a first roller for supporting the secondary flooring surface and guiding the secondary flooring surface on and off the core, wherein the first roller is free spinning; and
a second roller for supporting the secondary flooring surface and guiding the secondary flooring surface on and off the core, wherein the second roller is driven by at least one roller motor and the at least one roller motor is controlled by a roller drive unit.
13. The system of claim 12 , wherein the core drive unit controls a torque of the at least one core motor while the secondary flooring surface is rolling onto the core and the core motor drive unit controls a speed of the at least one core motor while the secondary flooring surface is rolling off the core, and wherein the roller drive unit controls a speed of the at least one roller motor.
14. The system of claim 13 , further comprising a frame for supporting the core and the secondary flooring surface, wherein the frame moves vertically along a pair of end shafts as the secondary flooring surface rolls on or off the core.
15. The system of claim 12 , further comprising a transducer, which determines the relative position of the core.
16. The system of claim 12 , wherein the secondary flooring rolls through a front of the system and the second roller is located between the first roller and the front of the system.
