The lower end 3a of the flange of the H-shaped steel 3 placed in this position is held by the claw 2.
The conditions under which the H-shaped steel does not fall when it is pushed forward and transported while sliding are the overturning moment M1 and the stabilizing moment M.

Indicates the state in which In the following description, since the transfer and the claw 2a move together, the movement of the transfer will be described as the movement of the claw 2a.

ないからである。When the H-shaped steel to be transported arrives within the initial transport section L2 and transport is started, the claw 2a first moves from a stopped state (velocity v0 = 0) to the air transport section L1 with an acceleration α1.
Accelerate to the end point P2. Acceleration α1 in this case
is not the acceleration α expressed by equation (2), but is an acceleration that can be set arbitrarily. In other words, the claws 2a within the air-feeding section L1 are merely air-feeded and do not come into contact with the H-shaped steel of the material to be conveyed.

の実態に応じて経験的に定めて差し支えない。When reaching point P2, the claw 2a is maintained at a constant conveyance speed v1, and moves within the initial conveyance section L2 at this conveyance speed v1. During the movement, the claw 2a comes into contact with the lower end of the flange of the H-beam placed on the skid, and slides the H-beam at the conveyance speed v1 until the claw 2a reaches the end point P3 of the initial conveyance section L2. transport. The conveyance speed v1 in this initial conveyance section L2 is the speed determined by formula (■), which is less than the speed determined by the ratio B/A of web height and flange width, the coefficient K determined by equipment conditions and product conditions, and the acceleration/deceleration time t. If so, the initial transport section L

Here, the acceleration/deceleration time t is a minute time from when the H-section steel in a stationary state begins to move until it reaches a constant speed v1, but in practice it may be determined empirically depending on the actual condition of the equipment.

転倒することはない。Subsequently, when the claw 2a reaches the end point P3 of the initial conveyance section L2, that is, the start point of the latter conveyance section L3, it starts accelerating at an acceleration α2. Acceleration α2 is the acceleration determined by formula (2), and if the acceleration is less than this, the bicycle will not fall during acceleration.

The latter conveyance speed v2 is the speed at which the H-section steel is conveyed the longest distance within the latter conveyance section L3, and can be set, for example, to the maximum speed of the transfer equipment capacity.

The same conditions were used: the total distance from the point P1 to the conveyance end point P4 was 5.4 m, and the latter conveyance speed v2 was 1.0 m/s.

Depending on the arrival of steel, a speed command may be given to the transfer drive motor via the thyristor conversion device. Of course, it is also possible to give a speed instruction each time depending on the H-beam to be transported by manual operation.
