6. Basic Layouts
6.2.2 Vertical Conveyor Arrangement Install a brake or anti-reverse clutch on the driver in case the machine stops while conveying objects. This is shown in Figure 6.7. The chain may vibrate considerably due to the characteristic frequency of the chain, impact period of the driven shaft, or the polygonal action of the chain and sprocket. Therefore, install a guide shoe to prevent vibration.
6.2.3 Inclined Conveyor Arrangement An inclined conveyor is set up the same way as a horizontal conveyor.
6.2.4 Horizontal Circulating Conveyor Arrangement If the shafts are vertical (Figure 6.8), install a guide roller or guide shoe to the chain to keep the chain from hanging down. This method is covered in more detail in the Applications Section of this book. NOTE: For all conveyors, the use of a take-up is suggested. Take care not to overtension the chain, or the result will be increased wear between the pin and bushing. Also, if there is a corner roller guide, bushing/roller wear will occur. There must be adequate take-up allowance.

6.3 SUPPORTING THE ROLLER OF A CONVEYOR CHAIN Support both the conveying side and the return side of the chain vertically and restrain them horizontally. Figure 6.9 shows examples of supporting each type of roller and attachment.
