Overhead hoist transfer system, overhead hoist transfer, moving kit

An overhead hoist transfer applicable for an overhead hoist transfer system, the overhead hoist transfer system including a plurality of lower straight rails and a plurality of upper rail sets, wherein the plurality of lower straight rails are installed in a position close to a ceiling in a factory, the plurality of lower straight rails are disposed side by side, a first lower straight rail and a second lower straight rail of the plurality of lower straight rails are on a same side, and an end of the first lower straight rail and an end of the second lower straight rail are disposed at an interval to form a branching gap, the end of the first lower straight rail and the end of the second lower straight rail forming the branching gap are respectively connected to a lower turn rail, the plurality of lower straight rails form one or more of the branching gaps, each of the upper rail sets includes an upper straight rail and an upper turn rail, each of the upper rail sets is adjacent to one of the branching gaps, and the upper turn rail is disposed above the lower turn rail connected to one of the lower straight rails that forms the branching gap;

• the overhead hoist transfer comprising:
• a frame for carrying a to-be-transferred object;
• and
• at least one moving kit disposed on the frame, and the moving kit including:
• a control module;
• at least one body;
• at least two drive wheel sets respectively disposed on two opposite sides of the body, wherein each of the drive wheel sets is adjacent to a lower end of the body, each of the drive wheel sets includes at least one drive wheel, and the control module controls each of the drive wheel sets to allow each of the drive wheels to move on the lower straight rail;
• two switching modules electrically connected to the control module;
• and
• at least two upper guide wheels, each of the upper guide wheels connected to one of the switching modules and disposed at an upper end of the body, wherein each of the upper guide wheels abuts against the upper turn rail or the upper straight rail, and the control module controls each of the switching modules to allow the corresponding upper guide wheel to move toward or away from the body along an inclined path relative to the body;
• and
• wherein the control module receives transfer information, and when the control module determines that the overhead hoist transfer is about to pass through the upper rail set according to the transfer information, the control module controls at least one of the switching modules to allow the corresponding upper guide wheel to move toward or away from the body along the inclined path;
• wherein a distance between a lower edge of the upper straight rail included in one of the upper rail sets and a plane where the lower straight rail is located is not equal to a distance between a lower edge of the upper turn rail included in the one of the upper rail sets and the plane.
