5. The guide of claim 4, wherein the height of the guide hole increases as the upper and lower guide fingers extend laterally from the guide body.

6. The guide of claim 5, wherein the guide bore terminates at the guide body.

7. A guide as claimed in claim 6, wherein a bearing is located at the end of the guide hole, the bearing rotating in the direction of the path travelled by the belt to reduce friction of the belt against the guide.

10. The guide of claim 9, wherein the lower contact surface is at least partially circular.

Technical Field

The present invention relates to conveyor systems, and more particularly, to systems for guiding a belt in a conveyor system.

Background

Conveyor systems can transport goods, packages, cartons, and other objects in various types of environments and are often used in the manufacturing and transportation industries. Complex conveyor systems typically require multiple conveyor lines and lanes that cooperate to transport or sort objects, as well as various peripheral devices (e.g., sensors, solenoids, motors, etc.) associated with each conveyor lane.

Tracking of the conveyor belt may depend on the manufacturing accuracy of the conveyor belt. However, without a tracking mechanism, the conveyor belt would typically track to the left or right after use. The belt may rub against the conveyor belt system due to tracking to the left or right. Such friction often results in conveyor belt noise, belt wear, and belt failure.

Maintaining alignment of the conveyor web or belt material on the rollers or pulleys has been a common problem. The solution for improving the realignment rate of the tracking roller is not important. One way to solve this problem is to use some type of limiter to push the belt in a certain direction once it has moved to the extreme position. While this method helps to quickly correct a misaligned belt, the limiter may damage the edges of the belt or the material moving on the rollers. Another approach is to increase the angle at which the grooves or ribs are aligned relative to the circumference of the roll. By increasing the angle of inward movement of the helical groove or rib, the speed of inward movement of the belt can be increased.

Disclosure of Invention

The belt tracking guide of the present invention provides a fixture to a side rail of a conveyor system. In one embodiment, the conveyor system provides two side rails. A belt moves between two rails to carry objects through the conveyor system. The guide rails are fixed to the side rails so that the belt can travel near the guide rails.

Each guide provides an upper guide finger and a lower guide finger. The guide fingers form guide holes between the fingers. The belt passes through the guide holes between the guide fingers. The belt contacts at least one guide finger when the belt moves to the left or right. The guide fingers are inclined to move the belt away from contact with the guide. The guide plate contacts the belt, unseating the belt from the guide plate, and centering the belt. The belt contacts the guide fingers as the belt moves laterally. The guide fingers divert the belt from the guide, centering the belt.

The guide body of the guide is attached to the rail to secure the guide fingers to contact the belt. The guide fingers extend laterally from the guide body. The upper guide fingers are inclined upwardly as the guide fingers extend laterally from the guide body. When the next guide finger extends laterally from the guide body, the lower guide finger is inclined downward. Due to the inclination of the guide fingers, the height of the guide holes between the guide fingers increases when the guide fingers extend laterally from the guide body.

The guide bearing is also fixed on the guide body. The guide bearing is installed in the guide hole. If the belt runs too close to the guide body, the guide bearing will contact the belt. The movement of the bearing reduces wear on the belt. The belt does not contact the fixing but the bearing, thereby reducing friction.

Other objects, features and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.

It is an object of the present invention to retain the belt within the central portion of the conveyor assembly.

It is another object of the present invention to direct the belt toward the central portion of the conveyor assembly if the belt is off center.

It is another object of the present invention to reduce the downtime of the transport system.

It is another object of the present invention to allow fault-free operation of the conveyor assembly.

Another object of the invention is to simplify the mounting of the guide.

It is another object of the present invention to increase the life of the belt.
