Abstract:
An apparatus for changing and guiding a running direction of a conveyor belt, which is applied to a conveyor belt comprising a belt main body (1) wound between a main drive pulley (6) and a driven pulley (8) and structured such that, when the running direction of the conveyor belt is changed in the case that a changing portion (H) of the running direction (F) forms a concave portion on a transferring surface (G) of the conveyor belt, a zigzag motion when the belt main body (1) runs is prevented by engaging a guide body (3) linearly arranged in a back surface (2) of left and right side portions (25) and (26) of said belt main body (1) along a running direction (F) of the belt main body (1) with a guide groove (10) formed on a peripheral surface (7) of said main drive pulley (6) and a peripheral surface (9) of said driven pulley (8);wherein a running direction changing and guiding apparatus (11) for said conveyor belt comprises guide body supporting rollers (13) and (14) opposing to each other so as to form a pair and supporting an inner side surface (4) and an outer side surface (5) of the guide body (3) arranged on the back surface (2) of the left and right side portions (25) and (26) of the belt main body (1) by peripheral surfaces (15) and (16) thereof, a belt pressing roller (17) for pressing the left and right side portions (25) and (26) of the belt main body (1) from the transferring surface (G) side toward the guide body supporting rollers (13) and (14) opposing to each other so as to form a pair by a peripheral surface (18) thereof for positioning said guide body (3) between the guide body supporting rollers (13) and (14) opposing to each other so as to form a pair, and a running direction changing roller (19) arranged in parallel to said belt pressing roller (17), pressing the left and right side portions (25) and (26) of the belt main body (1) from the transferring surface (G) side by a peripheral surface (20) thereof and changing the running direction (F) of the belt main body (1) by moving the transferring surface (G) of the belt main body (1) along the peripheral surface (20).
