This known delivery device includes a cart movable to a warp beam delivery position, and a cart that is attached to the cart in the front and back direction (in the present invention, the side that is the side of the device to be delivered at the delivery position is forward, and the opposite side is the rear). (The other horizontal direction intersecting the front-rear direction is called the left-right direction). It includes a delivery means supported by a moving table and equipped with a transfer arm, and a driving means for moving the moving table in the front-rear direction with respect to the cart so that the beam is delivered to the transfer arm.

Each transfer arm corresponds to a beam receiving section provided on the device to be transferred, and is supported by a moving table so as to be angularly rotatable by a pivot shaft.

During transfer, each transfer arm is rotated angularly about a pivot line by other drive means, such as a jack, so that the
Lower the number by two.

When the beam is supported by the transfer arm and moved toward the moving platform or the device to be delivered, that is, toward the front end, the center of charge acting on the platform (center) shifts toward the front end. ,
As a result, the delivery device is tilted so that the front end is below the rear end, making the delivery operation unstable. For this reason,
The known transfer device furthermore arranges a plurality of anti-tilt means with auxiliary width, such as casters, at the front end of the mobile platform.

During delivery, the auxiliary wheels are brought into contact with the floor to receive the load acting on the movable table, and in this state are moved in the front-back direction together with the movable table. As a result, the tilt prevention means prevents the delivery device from tilting as the transfer arm moves.

(Problem to be Solved) However, in the known transfer device, the auxiliary wheels are moved on the floor while receiving a large load, so if the floor is uneven, a large force is required to move the moving platform. Moreover, when the auxiliary width goes over unevenness, the entire device tilts, making the delivery operation unstable.

The present invention is a machine mechanism that allows the moving platform to be moved without requiring great force even if the floor is slightly uneven, since there is no need to move the auxiliary width, and the delivery work is stable. The purpose is to provide a delivery device for
