Abstract
The invention includes a delivery conveyor to receive freshly baked products from baking pans of an automatic baking oven. The baking pans containing freshly baked products follow an arculate path at the discharge end of the oven for releasing freshly baked goods. The delivery conveyor positions at the discharge end of the oven and follows a curved path which is parallel to and closely spaced from the baking pans to prevent the newly baked goods from falling through a distance that is sufficient to cause breakage. The belt rotates about three rollers which are equipped with end sprockets and assumes a curved configuration by taking advantage of the natural sag in the upper belt path. Contoured guides which are affixed to the oven frame shape the slack side of the belt to the correct curved path.
Claims14
In a curved path delivery conveyor for function with a conveyor system the combination of
- A. an endless belt defining an upper path and a lower path,
- 1. said belt rotating about an upper positioned roller and a lower positioned roller,
- a. the said lower positioned roller lying in a first horizontal plane that is spaced from and below a second horizontal plane drawn through the upper positioned roller;
- B. means including a middle positioned roller to tension the lower belt path between the lower positioned roller and the upper positioned roller,
- 1. at least a portion of the said upper path of the belt being untensioned to form a curved configuration portion,
- 2. the said lower path being tensioned for belt rotation purposes,
- 3. the said conveyor system conveying containers through an arcuate path, the said curved configuration of the upper path being spaced from and parallel with at least a portion of the arcuate path followed by the containers;
- and
- C. the middle positioned roller being positioned intermediate the upper positioned roller and the lower positioned roller wherein the belt moves relative to the middle positioned roller,
- 1. the middle positioned roller being located in the spaces defined by the said first or second horizontal planes.
