A recently granted patent (Publication Number: US11772910B2) describes a linear conveyor system that is fixed to a base member. The conveyor system includes a transfer slider that moves along a rail on a frame. The frame is supported by a first support member on one end and a second support member on the other end. The frame is fixed to the base member through the first support member, while the second support member allows for relative movement between the frame and the base member to accommodate differences in thermal expansion and contraction.

The patent claims also describe a sliding mechanism that enables the relative movement between the second support member and the frame. The sliding mechanism includes a fitting portion that allows for sliding between the first support member and the second support member. Additionally, the sliding mechanism includes a tubular portion fixed to either the second support member or the frame, and an insertion portion fixed to the other component and inserted into the tubular portion for sliding.

The patent further describes variations of the sliding mechanism, including the use of an auxiliary rail and auxiliary slider that directly fix to either the base member or the frame and slide with respect to each other. The sliding mechanism allows for smooth and controlled movement of the frame and the transfer slider along the rail.

The patent also mentions the inclusion of a lifting and lowering device in the linear conveyor system. This device includes a lifting and lowering frame with a rail that is arranged linearly adjacent to the rail of the frame of the fixed module. The lifting and lowering device is designed to lift and lower the transfer slider, providing additional functionality to the conveyor system.

Overall, this granted patent presents a linear conveyor system with a unique sliding mechanism that allows for relative movement between the frame and the base member. The system provides smooth and controlled movement of the transfer slider along the rail, accommodating differences in thermal expansion and contraction. The inclusion of a lifting and lowering device further enhances the functionality of the conveyor system.
