Description

[Detailed description of the invention] (Field of industrial application) The present invention is designed to turn the shaped steel smoothly, prevent scratches, etc., and increase the turning ability of the shaped steel.
The present invention relates to a section steel turning device in which a plurality of sets of turning devices are arranged in the direction of section steel transport so that the arrangement space can be made as narrow as possible.

(Prior art) As shown in Fig. 11, a conventional example of a device for turning shaped steel is a turning device for turning shaped steel 19, which is fed by a chain conveyor or the like.
A star wheel 23 fixed to a shaft 22 rotatably held on a pedestal 20 by a bearing 21 is rotated in the direction of the arrow in the figure by a drive source (not shown).
As shown by the imaginary lines, the section steel is turned from vertical to horizontal or from horizontal to vertical.

(Problems to be Solved by the Invention) Normally, when a roller table is used to convey shaped steel to the next process, processing efficiency is poor because the above-mentioned turning device usually sends out the shaped steel one by one after turning.

In addition, in the case of high-temperature materials, it is necessary to measure the temperature rise commensurate with processing efficiency, and materials with irregular cross-sectional shapes such as rails will bend when cooled, so the rails will Because the equipment would skid or fall over suddenly, it was difficult to secure the correct position after turning, and there were problems in terms of energy conservation, equipment configuration, and quality, such as damage.

In addition, if multiple sets of this conventional star wheel type turning device are installed on the supply floor a of the shaped steel in the conveying direction, they must be arranged so that the arm of the star wheel and the shaped steel do not interfere with each other. However, considering the bending of the shaped steel, etc., the star wheel arms had to be arranged at a pitch that would not interfere with each other. Therefore, a considerably large installation space was required.

(Means for solving the problem) In order to solve this problem, the present invention includes a push arm 4, a receiving arm 5, and a stopper arm 6 for preventing the section steel from slipping on the supply floor a. Each of the three arms is provided on the common shaft 3 so as to be tiltable individually, and the three arms constitute a set of turning devices that turn the shaped steel by 90 degrees, and the turning devices are arranged in plural sets in the direction of conveying the shaped steel.
The pusher arm is arranged on a supply floor a of the shaped steel, the tilting angle of the push arm is set to a tilting angle until the center of gravity of the shaped steel hangs on the receiving arm, and the length of the stopper arm is set so that the length of the stopper arm is the same as that of the shaped steel supplied. This is a shape steel turning device characterized by having a length that does not interfere with the neighboring shape steel when it is turned to a position where it does not slip on the floor.

(Function) The push arm 4, the receiving arm 5, and the stopper arm 6 for preventing the shaped steel from slipping on the supply floor a are each provided on the common shaft 3 so that they can each be tilted individually, so that the shaped steel can be kept at rest. This can prevent scratches.
In particular, when the center of gravity of the shaped steel moves from the push arm to the receiving arm, the push arm and the receiving arm can be tilted in synchronization, so the shaped steel can be rotated without shifting. The stopper arm 6 prevents the shape steel from shifting even when the push arm returns, so the accurate position after rotation can be ensured. Since it is reliably transferred to the table, troubles such as inability to transport are eliminated.

Furthermore, the tilting angle of the push arm is set to a tilting angle at which the center of gravity of the shaped steel is tilted to the receiving arm, and the length of the stopper arm is set such that the length of the stopper arm is adjusted to a position where the shaped steel does not slip on the supply bed. Since the length is set so that it does not interfere with the adjacent shaped steel, the pitch spacing between the turning devices is reduced to about 1/2, making it possible to reduce the installation space for multiple sets of turning devices to about 2/3.

Of course, since a plurality of sets of turning devices can be provided, the turning processing capacity can be greatly increased.

(Example) Embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 and 2, three advancing/retracting devices 9, 9A, and 9B are provided at both ends of the lower portion of the pedestal 1. Although this advancing/retracting device is illustrated as a cylinder in this example, it may be constituted by a motor or the like. A bearing 11 is provided on the pedestal 1.
A long drive shaft 10 is fitted therein. In the present invention, three connecting links 7, 7A, and 7B are arranged for one of the frames 1 as illustrated in FIG. In this example, three receiving arms 5 are installed on the connecting link 7 at predetermined intervals in the length direction, three push arms 4 are installed on the connecting arm 7A, and three stopper arms 6 are installed on the connecting arm 7B. Each piece is attached to a shaft. Of course, this number shows an example in which three units are installed, but it goes without saying that this number can be increased or decreased depending on the scale of the equipment. Connecting links 7, 7A, 7B with each arm 4, 5, 6 attached as a shaft
As shown in FIGS. 3 to 5, they are connected to the advancing and retracting devices 9, 9A, and 9B via links and arms, respectively. In other words, the connecting link 7A illustrated in FIG. 3, in which the push arm 4 is mounted via the common shaft 3 with a pin 12A, is connected to the advancing/retracting device 9A. The connecting link 7A is connected to the advancing/retracting device 9A via pins 13A and 16A via the link 14A and the end fitting 17A as an intermediary to the arm 8A. Further, the receiving arm 5 shown in FIG. 4 is connected to the pin 12 via the common shaft 3.
The connection link 7 and the advancing/retracting device 9 are connected together,
The connection between the connecting link 7B, in which the stopper arm 6 shown in FIG. 5 is axially mounted at 12B via the common shaft 3, and the advancing/retracting device 9B is the same as that of the above-mentioned connecting link 7A, so a description thereof will be omitted.

That is, in the present invention, as shown in FIGS. 1 and 2, a push arm 4 is rotatably held on a common shaft 3 held by a bearing 2 on a pedestal 1 and rotates a shaped steel rail 18 in this example, Rail 18 in the middle of turning
A receiving arm 5 that supports and receives the rail 18, and a stopper arm 6 that prevents the rail 18 from sliding sideways are arranged, and the connecting links 7, 7A, 7B and the arms 8, 8A, 8B are arranged.
They are respectively driven by advancing and retracting devices 9, 9A, and 9B via.

Next, the operation will be explained with reference to FIGS. 6 to 10 regarding the rotation of the curved rail 18 (the rail 18 in each figure shows a longitudinal section and also shows the curved portion). As shown in FIG. 6, the push arm 4,
The receiving arm 5 and the stopper arm 6 are waiting below the supply level a of the rail 18.
Now, when the rail 18 reaches a predetermined position, the receiving arm 5 rises, and then the push arm 4 rises, and the rail starts turning.

As shown in FIG. 7, when the push arm 4 reaches a predetermined position, the rail 18 continues to rotate while keeping the intersecting angle θ between the push arm 4 and the receiving arm 5 constant.

Next, as shown in Figure 8, the rail 18 stops at a position where the center of gravity is completely on the receiving arm 5, the stopper arm 6 rises, and the pusher arm 4 waits so as not to interfere with the rail that is in the middle of turning. retreat to position. When the push arm 4 retreats, as shown in FIG. 9, the rail 18 continues to rotate while preventing the rail from sliding sideways with the stopper arm 6, and after the rail 18 reaches a position where it does not slip, the stopper arm 6 also retreats. and the rail 18 as shown in FIG.
complete the rotation.

In this way, the stopper arm 6 works effectively against the curved material to be rotated.

In the device of the present invention, a proximity switch using magnetism can be used as an example of a position detection device for the linked operation of the receiving arm 5, push arm 4, and stopper arm 6, and this proximity switch can be implemented using a known means. It's fine.

(Effects of the invention) According to the invention, it is possible to have multiple arm configurations, so not only can multiple rows of rails be turned at the same time, but since the stopper arm is provided, even curved rails can be turned. Since there is no sideways sliding of the rail during rotation, scratches can be prevented. Furthermore, since the rail spacing after turning can be accurately ensured, excellent effects are brought about in terms of equipment configuration, work efficiency, economy, and quality. Furthermore, the pitch interval of the turning devices is reduced to about 1/2, and the installation space for multiple sets of turning devices can be reduced to about 2/3.
