Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a transportation device used for transporting steel materials for inspection and cleaning of steel materials.

[0002]

[Prior art]

 Generally, steel materials are transported by horizontally arranging rollers in parallel and rotating the rollers, or by transporting steel materials on a conveyor belt.

[0003]

[Problems to be solved by the device]

 It is often necessary to position the steel material in order to perform surface inspection, dimension measurement, or steel material cleaning work on the steel material transfer line. The present inventor manufactured a device for rotating a roller 2 having a V-shaped constricted portion shown in FIG. 3 as a steel material conveying device capable of performing the above-described positioning on a conveying line. The apparatus shown in FIG. 3 can position the steel material by bringing the side surface of the steel material 1 into contact with the V-shaped constriction portion, and can carry the steel material into a predetermined position.

However, in a conveying device that rotationally drives a roller having a V-shaped constriction, the peripheral speed of the roller surface is different between the valley portion and the mountain portion. It was found to be one of the causes of scratches on the surface. In view of the above problems, it is an object of the present invention to provide a steel material conveying device that can carry a steel material into a predetermined position while preventing the steel material from being damaged.

[0005]

[Means for Solving the Problems]

 The inventor of the present invention moves the rotatable roller pair arranged in such a manner that their roller shafts are substantially V-shaped in the conveying direction, thereby preventing damage to the steel material loaded on the roller pair. They found that they can be transported and arrived at the present invention. That is, according to the present invention, a rotatable roller pair arranged such that the roller axes of the pair are substantially V-shaped, a rotation resistance imparting means for imparting rotation resistance to the roller pair, and the roller pair are provided. A steel material transporting device comprising: a supporting frame; a transporting band in which a plurality of the frames are fixed intermittently; and a drive device for driving the transporting band.

[0006]

[Action]

 The most characteristic feature of the present invention is the use of rotatable roller pairs in which the pair of roller axes are arranged in a substantially V shape. The rotatable roller pair rotates due to friction with the steel material when the steel material is loaded into the transportation device of the present invention, and can prevent scratches due to friction between the transportation device and the steel material during loading. To do. Further, by making the roller axis lines of each other substantially V-shaped, the steel materials are supported by the roller pairs from two directions, and the steel materials do not move to the left or right during transportation, and are passed on a predetermined transportation line. be able to.

In the present invention, the V shape means, in other words, the arrangement is such that the valley portion is formed by the roller pair. In particular, when the roller axes are set to approximately 90 degrees, the roller surfaces can support, for example, the lower surface and the two side surfaces of the steel material having a square cross section in parallel, and the arrangement is convenient for transporting the square steel cross section. Become.

In the present invention, another important feature is that a plurality of frames for supporting the roller pair are intermittently fixed to drive the transport belt. Since it cannot be conveyed only by the above-mentioned roller pair, means for moving the steel material on the roller pair is required. Therefore, in the present invention, the roller pair is not driven to rotate, but the frame supporting the rollers is moved. This is because it is difficult for a device that rotationally drives a pair of rollers to perfectly match the rotations of the rollers with each other, which may cause scratches. In the present invention, the conveyor belt is used as a means for moving the frame. Specifically, a chain or a belt can be used as the transport belt. A wheel, for example, is provided as a drive device in this transport belt.

As described above, the roller pair of the present invention needs to be rotatable due to friction when the steel material is carried in. However, the steel material moves on the roller due to the inertial force when moving the roller pair. Then, it becomes impossible to carry out a predetermined transport operation. Therefore, it is necessary to provide the roller pair with a rotational resistance that prevents the steel material from moving due to inertial force during the steel material transportation. Therefore, in the present invention, a rotation resistance applying means for applying rotation resistance to the roller pair is provided. As the rotation resistance imparting means, a brake may be provided on the roller, or the rolling friction of the roller itself may be adjusted.

【Example】

 An example of the steel material conveying device of the present invention is shown in FIG. The steel material 1 having a square cross section to be transported is carried onto a pair of rotatable rollers 2 mounted on a frame 3. At this time, the roller 2 is rotated by the steel material 1 that is carried in, and has a structure that prevents the occurrence of scratches during loading. The steel material 1 on the roller has the positional relationship shown in FIG. 2 when viewed from the conveying direction of the steel material 1. As shown in FIG. 2, in the apparatus shown in FIG. 1, the angle between the pair of roller shafts 6 is 90 so that the two surfaces of the steel material 1 having a square cross section come into contact with the respective roller surfaces of the pair of rollers. It was set to have a V-shaped degree. This angle can be changed as appropriate in consideration of the size of the steel material and the transportation resistance.

Next, the frame 3 is moved by the endless transfer chain 4 which is moved by rotating the wheel 5 of the transfer device, and the steel material 1 is moved in the arrow direction shown in FIG. At this time, the roller resistor 7 comes into contact with the roller surface and imparts a rotational resistance so that the steel material does not move on the roller 2 due to the inertial force, so that the steel material 1 is transported by the movement of the transport chain 4. According to the conveying apparatus of the present invention shown in FIGS. 1 and 2, the steel material 1 can be conveyed while being positioned by the pair of rollers 2. Moreover, since it is not moved by driving the roller, it is possible to prevent scratches due to sliding between the roller surface and the steel material surface.
