Product dispenser for a vending machine

In a vending machine having a cabinet including a transparent panel and a discharge chute for dispensing products from the machine, a number of product dispensers mounted in horizontal arrangement on shelves within the cabinet, each of the product dispensers having a discharge end being in communication with the discharge chute and being disposed adjacent the transparent panel, and a drive operably attached to each product dispenser, at least one of the product dispensers comprising:

• a conveyor including a drive pulley operably attached to the drive, a continuous belt disposed about and driven by the drive pulley, and dividers attached to and extending out from the belt and spaced along the belt at predetermined intervals forming a number of product cavities;
• wherein the drive pulley includes a horizontally disposed axis and the belt is disposed such that the dividers extend up from the belt, wherein the belt has an underside including timing projections, and the drive pulley has an outer surface including timing grooves disposed to matingly receive the timing projections and wherein the conveyor further includes a U-shaped frame having spaced upstanding legs and a horizontal floor, the frame being secured to the shelf and disposed to rotatably receive the drive pulley at one end and an idler pulley at the opposite end, and wherein the floor includes longitudinal ridges disposed to engage the underside of the belt, whereby the contact area between the belt and the floor is minimized to reduce friction;
• and
• each of the dividers comprising a sheet of flexible transparent material, whereby a product disposed within the product cavity adjacent the transparent panel can be seen by the user through the transparent divider.

A method of modifying a vending machine having a cabinet including a transparent panel and a discharge chute for dispensing products from the machine, a number of helical product dispensers mounted in horizontal arrangement on shelves within the cabinet, each of the helical product dispensers having a discharge end being in communication with the discharge chute and being disposed adjacent the transparent panel, and a drive operably attached to each helical product dispenser, the method comprising the steps of:

• removing at least one of the helical product dispensers from the machine;
• attaching an adapter to the drive of the removed helical product dispenser;
• replacing the removed helical product dispenser with a replacement product dispenser comprising:
• a conveyor including a drive pulley operably attached to the drive, a continuous belt disposed about and driven by the drive pulley, and dividers attached to and extending out from the belt and spaced along the belt at predetermined intervals forming a number of product cavities;
• and
• each of the dividers comprising a sheet of flexible material whereby a product disposed within the product cavity adjacent the transparent panel can be seen by the user through the transparent divider.
