Various embodiments are directed to a guard apparatus for a conveyor system. The conveyor system comprises a plurality of rollers rotatably disposed between a pair of side frames of the conveyor system. The guard apparatus comprises a top cover and a first flange. The top cover is disposed in a first gap formed between a first roller and a second roller of the plurality of rollers. The first flange extends from a first end of the top cover into a second gap formed between a first end face of the first roller, a second end face of the second roller and a corresponding side frame of the conveyor system.

In one aspect, a transfer guard member having a body for being positioned in a gap intermediate conveying surfaces, an upper portion of the body for spanning the gap and outer portions of the upper body for slidingly engaging the conveying surfaces, and a pair of spaced, resilient legs having distal end portions for resiliently and slidingly engaging the conveying surfaces. In another aspect, a transfer guard member having a body and at least one attachment member of the body configured for being detachably fixed to a mounting bar. The body has at least one recess adjacent the attachment member for receiving at least one attachment member of another transfer guard member fixed to the mounting bar so that upper transfer surfaces of the attachment members are adjacent one another.

Apparatus for joining electronic components to an electronic substrate are disclosed, including a frame, a first conveyor section and a second conveyor section, and a support device. The first and second conveyor sections are supported by the frame and arranged spaced apart from each other along a conveying direction of the electronic substrate, and have first and second conveying surfaces, respectively. The support device is coupled to the frame and movable between a supporting position and a rest position relative to the first conveyor section and the second conveyor section. The support device has a supporting surface. In the supporting position, the support device is at least partially located and held in a receiving area between the first and second conveyor sections and the supporting surface is substantially flush with the first conveying surface and the second conveying surface. In the rest position, the support device exits the receiving area.

A roller transfer plate for moving product through a conveyor transition includes a plate and a center spindle extending through the plate. A plurality of axles are arranged radially in the plate relative to the center spindle and a plurality of balls or rollers are positioned on the axles and arranged concentrically.
