Arms are provided to face each other on the left and right, and a roller is provided at the rotating end of each arm so that it can contact the front surface of the upright and roll in the vertical direction when the bolster truck moves toward the bolster truck fixing part. , the connecting cable is passed between the rotating ends of the arms of adjacent bolster trucks, and these arms are laid along each other.

When the bolster cart moves to a position in front of the front of the upright, the roller at the rotating end of the arm moves away from the upright, causing the arm to protrude upwards and prevent the arm from interfering with columns in front of the press or blocking the passage. There is nothing to do. When the bolster truck moves from this position toward the bolster truck fixing part (to the rear), the rollers will eventually come into contact with the front of the upright, and as the bolster truck moves further backwards, the rollers will roll downward on the front of the upright. The arm gradually rotates downward and begins to protrude forward. Conversely, when the bolster truck moves forward from this position, the roller rolls upward on the front of the upright, causing the arm to gradually rotate upward until the roller separates from the upright and the arm projects upward. become. Therefore, the connecting cable does not interfere with the upright.

According to the bolster bogie coupling device of this invention, the power supply cable is connected to any one of the plurality of bolster bogies, and adjacent bolster bogies are interconnected by the coupling cable. Power can be supplied to multiple bolster trucks from one power supply cable. In addition, on the front part of the opposing part of the adjacent bolster truck, there is an arm that can rotate between a position protruding forward from the bolster truck and a position protruding upward, and is biased in the direction of upward rotation. A roller is provided at the rotating end of each arm so that it can contact the front surface of the upright and roll up and down when the bolster truck moves toward the bolster truck fixing part. is passed between the ends of the arms of adjacent bolster carts and along these arms, so that when the bolster cart moves, the arms and connecting cables are connected to uprights, columns in front of the press, etc. as mentioned above. There are no drying beds or blocking passages. Therefore, the space in front of the press can be used effectively.
