Description

[Detailed Description of the Invention] The present invention relates to an improvement of a receiving device such as a pipe material.

Generally, the pipe material transferred on the skid rail is temporarily stopped at the transfer end by a protrusion provided at the tip of the skid rail, and then transferred to a roller conveyor or the like via a skid rail as is known in the art. At the time, the following pipe materials, etc., transferred on the skid rail collided with the above-mentioned protrusions, producing noise, and also caused dents on the surface of the pipe materials, etc., which were disadvantageous.

In order to eliminate such drawbacks, the present invention provides a receiving plate at the outlet end of the skid rail that is inclined upward with respect to the transfer direction of pipe materials, etc., so that the receiving plate is raised steeply when moving upward, and steeply when moving downward. The object of the present invention is to provide a receiving device for a pipe material, etc., which allows the pipe material to be gently lowered to prevent a subsequent pipe material, etc., from colliding with the projection.

The embodiments of the present invention will be explained with reference to the drawings.
is a receiving plate arranged parallel to the skid rail 2 at the open end of the skid rail 2, and is inclined upward with respect to the transfer direction of the pipe material, etc.

Reference numeral 3 denotes a leg body which is integrally vertically hung on the lower surface of the receiving plate 1, and one end of an upper lever 4 and a lower lever 5 are attached to the upper and lower ends of the leg body, respectively, and are rotatable by pivots 6 and 7. They are pivotally connected and together with the legs 3 constitute a pantograph mechanism 8. Reference numeral 9 denotes a pivot shaft fitted into the center of the upper lever 4, which is supported by a bearing 12 attached to the top surface of the pedestal 13 and connected to the deceleration motor 11 via a chain coupling spring 14.
Furthermore, a cam clutch 10 is interposed between the pivot shaft 9 and the upper lever 4. Cam clutch 10
As shown in FIG. 3, the boss part 4 of the upper lever 4
A gradual gap 17 is provided between the inner surface of the driven wheel 15 and the cam body 16 into which the driven wheel 15 is fitted and fixed to the pivot shaft 9, and the ball 18 is fitted into the gap 17.
A pusher 20 pressed by a weak spring 19 is inserted between the protrusion 16a of the cam body 16 and the upper lever 4 is freely rotated in the direction in which the receiving plate 1 moves upward. is configured to restrict rotation of the receiving plate 1 in the downward direction. 21 is an air cylinder connected to the other end of the upper lever 4;
It is attached to the pedestal 13 via a bracket 22. The other end of the upper lever 5 is made parallel to the upper lever 4 and pivoted to a bracket 23 attached to the pedestal 13 vertically below the pivot shaft 9. A pantograph mechanism 8 is configured.

To explain the operation of the above embodiment, at the conveying end of the skid rail 2, the skid car 24
is actuated to transport the pipe P received by the protrusion 2a of the skid rail 2 onto the roller conveyor 25. At this time, if the air cylinder 21 is driven downward, the upper part is moved around the pivot 9 as a fulcrum. The lever 4 rotates clockwise in the figure. At this time, the upper lever 4 is in the direction of rotation.
Since the boss portion 4a of the cam clutch 10 rotates without being restricted by the cam clutch 10, the leg 3 rapidly moves upward and the catch plate 1 protrudes above the upper surface of the skid rail 2, and the following pipe material P is held against the catch plate 1. It is received by the inclined surface of the

At the upper end of the receiving plate 1, the air cylinder 2
1 to upward movement, the upper lever 4 rotates counterclockwise and tries to move the catch plate 1 downward, but
A cam clutch 10 restricts rotation of the upper lever 4. On the other hand, the cam body 16 of the cam clutch 10 is fixed to the pivot shaft 9 by the deceleration motor 11.
If the receiving plate 1 is constantly driven in the direction shown by the arrow in FIG. As a result of the operation, the receiving plate 1 slowly rotates at the same speed via the driven wheel 15, and the receiving plate 1 gradually descends, and the pipe material P slowly rotates at the same speed.
It is fed out onto the skid rail 2 and abuts against the protrusion 2a at a slow speed.

As described above, the present invention provides a skid rail 2, which has a receiving protrusion 2a such as a pipe material protruding from its end, on the side of the outlet end thereof, parallel to the skid rail 2, and facing toward the protrusion 2a. An upwardly inclined receiving plate 1 is disposed, and one end of an upper lever 4 and a lower lever 5 are rotatably pivoted at the upper and lower ends of legs 3 hanging from the lower surface of the receiving plate 1, respectively. At the same time, the pivot shaft 9 is rotatably inserted into the central boss portion 4a of the upper lever 4, and the upper lever 4 is freely rotated in the direction of moving the receiving plate 1 upward between the pivot shaft 9 and the boss portion 4a. Cam clutch 10 that restricts rotation in the downward direction
Further, the pivot shaft 9 is always slowly rotated by a deceleration motor 11 in the direction in which the receiving plate 1 moves downward via the cam clutch 10, and the other end of the upper lever 4 is connected to the reciprocating direction of the upper lever 4. Since this is related to a receiving device such as a pipe made by connecting the rotating air cylinder 21, when the air cylinder 21 is operated in the direction in which the receiving plate 1 is raised, the upper lever 4 is regulated by the cam clutch 10. The receiving plate 1 can be rotated freely without any movement, and the receiving plate 1 can be raised rapidly to protrude from the upper surface of the skid rail 2. Therefore, the upwardly inclined surface of the receiving plate 1 allows the following pipes, etc. to be attached to the skid rail 2. It can be reliably received without delay before coming into contact with the protrusion 2a.

Furthermore, when the air cylinder 21 is operated in the direction in which the receiving plate 1 is lowered, the rotation of the upper lever 4 is regulated by the cam clutch 10 to prevent the receiving plate 1 from falling suddenly, and the deceleration that is constantly driven is controlled by the cam clutch 10. Since the shaft 9 is rotated by the motor 11 via the cam clutch 10 in a direction that loosens the restriction on rotation of the upper lever 4, the air cylinder 21 loosens the upper lever 4 in synchronization with the rotation of the shaft 9. Therefore, by gradually lowering the receiving plate 1, the pipe material, etc. can be fed slowly from the receiving plate 1 onto the skid rail 2, and it can be moved slowly without making noise or dents. It can be brought into contact with the protrusion 2a at a high speed.
