Abstract
A linear drive apparatus for moving a canon in a packaging machine from a first position to a second position is set forth. The apparatus includes first and second spaced apart guide rods and an engagement assembly that is disposed between and slidably engages the first and second guide rods. The engagement assembly is adapted to engage one or more cartons for movement between the first and second positions. The apparatus further includes a drive shall onto which a drive roller is disposed for co-rotation. A first drive belt is connected to the drive roller and disposed about the drive roller in a clockwise direction at a first end thereof while a second end of the first drive belt is connected to a first portion of the engagement assembly. A second drive belt is connected to the drive roller and disposed about the drive roller in a counter-clockwise direction at a first end thereof while a second end of the second drive belt is connected to a second portion of the engagement assembly opposite the first portion of the engagement assembly. The rotation of the drive shaft in a clockwise direction causes linear movement of the engagement assembly in a first direction along the guide rods and the rotation of the drive shaft in a counter-clockwise direction causes linear movement of the engagement assembly in a second direction opposite the first direction.
