Abstract

A module builder includes a wrap floor system including a wrap floor belt wrapped around a front belt sheave and a first drive system coupled to the wrap floor system. The first drive system includes a main drive belt coupled to a rear belt sheave and the front belt sheave, wherein in an engagement mode of operation the main drive belt is tensioned to rotate the rear belt sheave, and in a disengagement mode of operation the main drive belt loses tension to cease rotation of the rear belt sheave. The builder includes a second drive system coupled to a baler belt to drive the baler belt into a module forming chamber. The first drive system further includes one or more of a rear lower gate roller, friction wheel, wrap box roller, electric clutch, or motor to engage and drive the main drive belt.

First claim

The invention claimed is:

1. A module builder, comprising:
a baler belt operable in a module forming chamber;
a first drive system coupled to the baler belt, wherein the first drive system includes a rear lower gate roller configured to rotationally drive the baler belt into the module forming chamber;
a wrap floor system includes a wrap floor belt wrapped around a front belt sheave, wherein rotation of the front belt sheave moves the wrap floor belt; and
a second drive system configured to engage the front belt sheave to drive the wrap floor system and to rotationally move the wrap floor belt, the second drive system coupled to the rear lower gate roller, wherein in an engagement mode of operation the rear lower gate roller engages the second drive system to rotate the front belt sheave, and in a disengagement mode of operation the rear lower gate roller disengages from the second drive system to cease rotation of the front belt sheave.

2. The module builder of claim 1 , wherein the first drive system further includes a friction wheel coupled to the rear lower gate roller to rotationally drive the rear lower gate roller.

3. The module builder of claim 1 , further comprising:
a wrap assembly that stores a wrap roll of wrapping material, wherein the wrap assembly is configured to dispense the wrapping material from the wrap roll between the baler belt and the wrap floor belt; and
wherein the engagement of the wrap floor belt to the baler belt drives the wrap material into the module forming chamber.

4. The module builder of claim 1 , wherein the second drive system includes a plurality of interoperable gears to engage and drive the front belt sheave.

5. The module builder of claim 1 , wherein the second drive system includes a motor operably attached to engage and drive the front belt sheave.

6. The module builder of claim 1 , wherein the second drive system includes a main drive belt coupled to a rear belt sheave and the front belt sheave, wherein in an engagement mode of operation the main drive belt is tensioned to rotate the rear belt sheave, and in a disengagement mode of operation the main drive belt loses tension to cease rotation of the rear belt sheave.

7. The module builder of claim 6 , wherein the second drive system includes a drive sprocket coupled to a driven sprocket wherein the driven sprocket is rotationally coupled to the lower rear gate roller.

8. The module builder of claim 7 , further comprising:
a tensioner configured to engage the main drive belt to tension the main drive belt in the engagement mode of operation.

9. The module builder of claim 8 , wherein the tensioner is positioned partially between the drive sprocket and the driven sprocket.

10. The module builder of claim 1 , wherein the wrap floor system pivots to engage the baler belt during the engagement mode of operation.

11. The module builder of claim 1 , wherein the second drive system includes an electric clutch configured to operationally engage the rear lower gate roller.

12. The module builder of claim 1 , wherein the wrap floor belt includes a plurality of wrap floor belts that are operated by the first drive system.
