Slat conveyor

A slat conveyor comprising:

• slats arranged adjacent to one another to constitute an article conveying surface along a conveying path defined by frames;
• slat supporting members supporting respective slats and movable in a travelling direction in said conveying path, each of said slats having a first open connection portion located in a first end thereof and a second open connection portion located in a second end thereof opposite from said first end in said conveying path;
• at least one coupling shaft having a first shaft portion and a second shaft portion eccentric with respect to said first shaft portion;
• and
• means for preventing relative motion between said first shaft portion and said first connection portion comprising a disk member fixed on an axial end of said first shaft portion and having a diameter larger than that of an opening of said first connection portion, and a fixing member for fixing said disk member to said first connection portion to prevent relative rotation between said first shaft portion and said first connection portion,
• wherein said first and second connection portions of an adjacent pair of said slat supporting members are respectively engaged with said first and second shaft portions to couple said adjacent pair, and wherein said first shaft portion is located in one of a first position wherein said first shaft portion is displaced relative to said second shaft portion in said travelling direction and a second position wherein said first shaft portion is displaced relative to said second shaft portion in a direction opposite to said travelling direction to selectively vary a distance between said adjacent pair.
