CONSTITUTION:An easing down mechanism is provided with a resting part 4 which parallels a stopping part 3 supporting a round body 2 in the crossing direction and is supported movably in the vertical direction by means of a spring when the rollingly transferred round body 2 is stopped in the specific position or when it is stopped in the conversion of its transferring direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an easy-down mechanism in which a circular body such as a steel pipe to be transferred is quickly stopped when the circular body is stopped.

[0002]

2. Description of the Related Art When a cylindrical body such as a steel pipe is transferred, it may be stopped due to a change in the transfer direction, machining, testing, inspection, or the like. At that time, the circular body is supported in a V-shape in a direction traversing the circular body so that the circular body comes to rest quickly. If the V-shape is an acute angle and supports the side close to the lateral side portion of the circular body, the circular body quickly stands still. However, in the case of a thick circular body, the V shape becomes large and the mechanism becomes large. Further, when the V-shaped portion is worn and widened, the V-shaped portion does not stop immediately and the swing continues. In order to avoid making the mechanism large, there is a V shape having an obtuse angle so that the static force can be quickly obtained by the magnetic force of the magnet. In addition, Japanese Utility Model Publication No. 61-101529 discloses that
As shown in FIGS. 4 and 5, the pipes 2 rolling on the transport skid 1 are sent to the V-shaped stop portion 4 by the indexing device 3 one by one. At this time, the stopper 5 and the chair 6 regulate the swing of the tube body 1. Further, the U-shaped side 61 of the stopper 6 is elastically supported by the rubber 62 so as to absorb the kinetic energy of the tubular body 2 so as to stand still.

[0003]

However, the above-mentioned conventional mechanism which is designed to be stationary by the magnetic force of the magnet cannot handle products which are unfavorable to magnetization. In addition, there is a problem in that the one using rubber as the cushioning material for absorbing the kinetic energy cannot be applied to a line handling high temperature.

The present invention has been made in order to solve such a problem, and does not change the physical characteristics of the circular body to be transferred, and is an easy-down mechanism which does not cause any trouble even at high temperature. Aim to get.

[0005]

SUMMARY OF THE INVENTION An easy-down mechanism according to the present invention, when a circular body to be rolled and transferred is stopped at a specific position or stopped when the transfer direction is changed, the circle is moved. Parallel to the stop that supports the feature transversely,
In addition, a stationary member that is supported by a spring so as to be vertically movable is provided.

[0006]

In the present invention, since the stationary member which is parallel to the stop portion which supports the transferred circular body in the transverse direction and which is supported by the spring so as to be able to move up and down, the mechanism is simple. It is easy to apply, can be applied to those that do not like to be magnetized, and the circular body can be quickly stopped.

【Example】

Example 1. 1 is an elevational view showing the configuration of an easy-down mechanism according to an embodiment of the present invention, FIG. 2 is a view taken along the line AA of FIG. 1, and FIG. 3 is a partial cross-sectional view taken along the line BB of FIG. The transport skid 1, the circular body 2 such as a steel pipe, and the stop portion 3 are the same as the conventional ones. A stationary member 4 has a T-shaped cross section, is parallel to the conveyance skid 1, and has an upper surface which maintains a desired height in the middle of the stop 3. 5 is a mount, which has a columnar structure with an H-shaped cross section. 6 is a foundation on which the pedestal 5 is erected. One of the stationary members 4, which is the upstream side in the traveling direction of the circular body 2, is rotatably attached to a fulcrum shaft 7 fixed to an upper part of the pedestal 5. On the other side of the stationary member 4, which is the downstream side in the traveling direction of the circular body 2, a knuckle joint 9 for connecting the upper part of the rod 8 is provided, and a metal bush 11 is inserted into the knuckle pin 10. The lower portion of the rod 8 is connected to a trunnion structure 12 provided in the middle portion of the gantry 5 so as to be vertically slidable.
The trunnion 13 of the trunnion structure 12 is attached to the trunnion receiver 14 fixed to the middle portion of the pedestal 5 by the metal bush 1
It is attached through 5. A trunnion slide bush 16 is interposed in the sliding portion between the rod 8 and the trunnion 13. A coil-shaped spring 17 is externally inserted in the intermediate portion of the rod 8 so as to press the knuckle joint 9 and the trunnion structure 12 with a desired force.

The stationary function of the circular body 2 having the above structure is as follows. Circular body 2 rolling on the transport skid 1
Rolls on the stop 3 and rides on the stationary member 4. At this time, the kinetic energy of the circular body 2 is absorbed by the spring 16 pressing the stationary member 4, and the stationary body 4 immediately stops without swinging. As a result, it is possible to quickly move to the next step.

Although the stationary member 4 has a T-shaped cross-section in the above embodiment, it has an I-shaped cross section.
The present invention is not limited to the other structures as well, and it is a design change that those skilled in the art can appropriately use other structures having similar functions.

[0010]

As described above, according to the present invention, a circular body such as a steel pipe that rolls and conveys can be stopped immediately by absorbing the impact, so that the transition interval to the next step can be shortened. Can be done, and surface defects due to impact can be reduced, so quality improvement,
It can be expected to improve productivity.
