[Detailed explanation of the idea] Industrial applications The present invention relates to a pipe conveying device.

BACKGROUND ART Conventionally, as a tube conveying device for conveying a horizontal tube in a horizontal direction perpendicular to its axis, one having a movable rail capable of supporting a plurality of tubes has been used. This movable rail is configured to be able to swing up and down about a fulcrum provided on the downstream side in the pipe conveyance direction, and has a horizontal position where a plurality of pipes can be supported stationary;
The swinging end is displaced upward and the plurality of tubes are controlled to be in a tilted position where the plurality of tubes can be urged to roll in the horizontal direction.

Problems that the invention aims to solve However, in conventional systems like this, adjacent pipes come into contact with each other, so movable rails are usually not used.
The problem is that the tube will not roll unless it is tilted at a large angle of about 15 to 20 degrees. Therefore, there are problems in that the working environment is dangerous, the noise generated when the tubes roll is large, and the tubes are easily damaged.

Therefore, the present invention aims to solve these problems and to enable the tube to roll without increasing the inclination angle of the entire movable rail.

Means for Solving the Problems In order to solve the above problems, the present invention is capable of supporting a plurality of pipes, and is also capable of vertically swinging around a first fulcrum provided on the downstream side in the pipe transport direction. a first movable rail, the first movable rail has a horizontal position and an inclination in which the swinging end portion thereof is displaced upward to urge the plurality of tubes to roll toward the downstream side in the conveyance direction. a first swing drive device that swings between positions, and a second swing drive device that swings between positions, and a second swing drive device that swings between positions, and a second swing drive device that swings the swing drive device around a second support point provided on a first movable rail portion on the upstream side in the pipe conveying direction in the vicinity of the first support point. a second movable rail that is vertically swingable at a position downstream of the second fulcrum in the pipe conveying direction; and a second movable rail that is interlocked with the first swing drive device and that is
When the movable rail reaches the inclined position, the second
A second movable rail is tilted at a steep angle, and a pipe at a position corresponding to the second movable rail is transferred.
The swing drive device has the following configuration.

With this structure, even if the first movable rail is gradually tilted, in the initial stage, the adjacent tubes on this first movable rail will come into contact with each other and will not roll. When the first movable rail reaches the inclined position and the second movable rail inclines at a steep angle, the pipe at the position corresponding to the second movable rail is given a large drop and rolls out. Then, due to the impact during this transfer operation, a small gap is created between the tubes, and the frictional force that was pressing against each other is released, so the tubes remaining on the first movable rail are subsequently carried out. It turns out.

Further, the swinging end portion 12 of the second movable rail 10 is disposed on the downstream side of the second support shaft 11 in the tube conveyance direction.

13 is a second swing drive device that swings the second movable rail 10 up and down. Here 14,15
are a pair of links constituting a toggle mechanism, and one ends of both links 14 and 15 are connected to each other. The other end of the link 14 is connected to the base plate 9 via a bracket 16, and the other end of the link 15 is connected to the swinging end 8 of the first movable rail 3 via a bracket 17. A suspension link 18 is connected to the swinging end 12 of the second movable rail 10, and the lower end of this suspension link 18 and the connecting portion between the two links 14 and 15 are connected to a tension link 19. are connected.

A frame 20 is provided at a portion of the first movable rail 3 corresponding to the second movable rail 10, and a tilting table 21 is attached to this frame 20.
At the lower end of the hanging link 18, there is a slope 21
A roller 22 is provided on which it can roll. Further, the suspension link 18 is provided with a pin 23, and the tension link 19 is formed with an elongated hole 24 in the longitudinal direction of the link that engages with the pin 23.

When the first movable rail 3 is in the horizontal position shown in FIG. 1, its upper surface position is aligned with the upper surface position of the wheel platform 1, or is configured to be slightly below it. In addition, the second movable rail 10
A slope portion 25 that slopes downward in the tube conveyance direction is formed in a portion of the first movable rail 3 corresponding to the tube transport direction. Reference numeral 26 denotes an unloading section provided on the downstream side of the wheel platform 1 in the pipe transport direction, and is constituted by a traverse truck or the like. Reference numeral 27 denotes a stopper for preventing the tube 2 from rolling, and is provided on the upper surface of the wheel stand 1 corresponding to the second movable rail 10.

Next, the operation based on the above configuration will be explained. First, when the first movable rail 3 is in the horizontal position as shown in FIGS. 1 and 3a, the second
The roller 2 of the suspension link 18 of the swing drive device 13 of
2 is supported on the upper surface of the inclined table 21. At this time, since the first and second movable rails 3 and 10 are aligned with the upper surface position of the wheel stand 1, the first tube 2 of the plurality of tubes 2 that have been conveyed on the wheel stand 1 hits the stopper 27. By being stopped by the two-wheel stand 1, it is stopped.

When transferring the pipe 2, the first swing drive device 7 is operated to tilt the first movable rail 3 and lift the pipe 2 from the ring platform 1. Figure 3b is the first
This shows a state when the movable rail 3 is slightly inclined. In this state, the tubes 2 are in contact with each other, so no rolling occurs.

In conjunction with this, the second swing drive device 13 is operated. That is, as the swinging end 8 of the first movable rail 3 is raised, the links 14 and 15 are opened, and the tension link 19 is displaced upstream in the pipe conveyance direction. At this time, the elongated hole 24 of the tension link 19 slides along the pin 23 of the hanging link 18, and during this sliding, the first movable rail 3 begins to tilt, so the second movable rail 10 does not operate. . When the elongated hole 24 of the tension link 19 engages the pin 23, the roller 22 begins to move the top surface of the ramp 21 toward the ramp. FIG. 8c shows the state at this time.

As shown in FIG. 8d, the roller 22 is connected to the inclined table 21
When the second movable rail 10 hits the slope part 25 of the first movable rail 3, the second movable rail 10 suddenly slopes at a steep angle due to its own weight, and is retracted below the slope part 25 of the first movable rail 3. At this time, the inclined part 25 protrudes above the stopper 27, and the leading pipe 2 supported by the second movable rail 10 passes the stopper 27 along the inclined part 25 and reaches the wheel platform 1. It is carried out to the carrying out part 26 from the tip. At this time, the tube 2 on the first movable rail 3
The frictional force of the above-mentioned collision is released due to the impact when the leading pipe 2 moves out, so that
It is rolled and carried out in the same way. In addition, at this time, the first
An inclination angle of about 3 to 5 degrees is sufficient for the movable rail 3.

Once all the tubes 2 on the first movable rail 3 have been carried out, the first swing drive device 7 is returned to its original position, both movable rails 3 and 10 are returned to the horizontal state, and the next tube 2
Waiting for the delivery.

Effects of the Invention As described above, according to the present invention, by simply inclining the first movable rail gradually until it reaches a predetermined inclination position, the second movable rail inclines at a steep angle. The pipe at the position corresponding to the first movable rail can be rolled out with a large drop, and the impact at this time can release the frictional force of the pipes remaining on the first movable rail, These pipes can also be carried out in succession, and the pipes can be rolled by simply tilting the first movable rail at a relatively small angle of inclination. It also makes less noise and prevents damage to the pipes.
