Abstract
A differential impulse conveyor includes a conveyor base,and a tray,movable in a forward direction to move goods with the tray and in a backward direction to slide goods along the tray. A pair of tray support members,interconnect the conveyor base in the tray. Each tray support member may be pivotally connected at a lower end of the conveyor base and pivotally connected at an upper end of the tray. An electrically powered linear motor,moves the tray forward and rearward. A connector support,for interconnecting the base and the tray, or for interconnecting any stationary member and a movable member, may include a linear bearing having an end surface with a radius for rolling engagement with a contact surface having a radius twice of that of the end surface to achieve the desired linear motion of the tray or movable member.
