Supply roll stand with payout and roll changing

A method of loading first and second supply rolls each including a core and dispensing material from the first and second supply rolls, the method comprising steps of:

• receiving the first supply roll via a lift support;
• moving the lift support to raise the first supply roll;
• unwinding the first supply roll via an unwind assembly as the lift support raises the first supply roll;
• receiving the first supply roll via a transfer support so that the first supply roll is transferred from the lift support;
• receiving the second supply roll via the lift support;
• moving the core of the first supply roll when the first supply roll is depleted of material;
• and
• unwinding the second supply roll via the unwind assembly when the first supply roll is depleted of material.

A supply roll stand for loading first and second supply rolls each including a core and dispensing material from the first and second supply rolls, the supply roll stand comprising:

• a frame including:
• a diagonally oriented lift member including a first slot;
• and
• a horizontally oriented transfer member including a second slot;
• an L-shaped lift support in the first slot and configured to receive the first supply roll and move along the lift member to raise the first supply roll;
• a lift actuator configured to drive the first roll support along the lift member;
• an unwind assembly pivotably connected to the frame, and configured to unwind the first supply roll as the lift support raises the first supply roll, the unwind assembly including:
• a roller configured to engage the first and second supply rolls;
• and
• an unwind actuator configured to drive the roller;
• and
• a J-shaped transfer support suspended from the transfer member in the second slot and configured to receive the first supply roll so that the first supply roll is transferred from the lift support;
• a transfer actuator configured to drive the transfer support along the transfer member;
• the lift support being configured to receive the second supply roll after the first supply roll is transferred to the transfer support,
• the transfer support being further configured to move along the transfer member for dispatching the core of the first supply roll when the first supply roll is depleted of material,
• the unwind assembly being further configured to unwind the second supply roll when the first supply roll is depleted of material.
