Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for transferring long steel materials, and more particularly, to transfer a plurality of long steel materials traveling in parallel on a conveyor to an adjacent mounting portion. At this time, the present invention relates to a transfer device capable of stably transferring the long steel materials without breaking the parallel posture.

[0002]

2. Description of the Related Art For example, in a long steel rolling mill for producing equilateral angle irons, channel steels and the like, a plurality of long steel materials after rolling and straightening are run on a conveyor in a parallel state to a constant size. After cutting and transferring these long steel materials of a fixed size to an inspection site downstream for inspection and sorting, the required number of steel plates are stacked and carried out of the system.

[0003] In order to inspect a plurality of long steel materials cut in a fixed length in this manner, inspection is performed by setting a first conveyor downstream of a rolling, straightening and cutting line from a first conveyor so as to intersect with the first conveyor. It is necessary to transfer the whole parallel to the second conveyor located in the yard. These long steel materials are
Generally, a traverser is used as a means for transferring from a conveyor to a second conveyor while maintaining a parallel posture. The traverser includes a push-up member that pushes the long steel material upward from the roller transfer surface, and the push-up member rises from a standby position below the roller transfer surface on the first conveyor while maintaining a horizontal posture. Then, after placing a plurality of long steel materials arriving on the rollers of the first conveyor, the steel materials are horizontally extended toward the second conveyor, and the long steel materials are positioned above the second conveyor, Next, the long member is transferred to the second conveyor by lowering the push-up member below the roller conveying surface of the second conveyor, and the push-up member retreats horizontally and returns to the standby position below the first conveyor. It is configured to repeat a so-called block motion.

[0004]

The above-described apparatus for transferring a plurality of long steel materials from a first conveyor to an adjacent second conveyor is sufficiently practical when the running speed of the long steel materials is not so high. Can be offered. However, recently, there is a demand for supplying a large amount of long steel materials over a large number of items, so that the production speed of a steel rolling mill tends to increase.
For example, the length of these long steel materials ranges from 5 m to 24 m, and the number of steel materials arranged in parallel on the conveyor may be 10 or more. Therefore, when the production speed increases, the kinetic inertia during running of the steel materials increases. It will be very large.

[0005] As described above, when the inertia of the long steel material when traveling on the conveyor becomes large, when a plurality of long steel materials are collectively transferred from the production line to the inspection line by the conventional traverser, the plurality of long steel materials are transferred in parallel. There is a drawback that the held posture collapses. That is, when a plurality of long steel materials cut at a fixed length and traveling on the first conveyor at a high speed are pushed up from the first conveyor by the above-mentioned traverser push-up member and placed, these long steel materials are put on the long steel materials. Due to the large inertia that is acting, the individual steels move by inertia on the push-up members, which results in a disturbed parallel attitude of the plurality of long steels. In this way, if the parallel posture of the long steel material collapses, it will not only hinder the inspection on the inspection line, but also because the steel material itself is heavy, it will not be possible to form an orderly stack, and the inspection line will not operate. This leads to serious harm such as forced to stop.

[0006]

SUMMARY OF THE INVENTION The present invention has been proposed in order to preferably solve the above-mentioned drawbacks inherent in the prior art transfer apparatus for long steel materials, and is intended to solve the above problem. When transferring a plurality of long steel materials traveling at a loading section adjacent to the conveyor, even if the running speed increases with an increase in the production speed of these long steel materials, the parallel posture is not changed. An object of the present invention is to provide a long-length steel material transfer device capable of performing orderly transfer without collapse.

[0007]

[0018]

Next, the operation of the transfer device according to the present invention will be described. As described above, a large number of the long steel materials 10 running in parallel on the first conveyor 12 are conveyed on the first conveyor 12 at a certain high speed. This long steel material 12 is placed in an inspection yard 14 at an appropriate
As shown in FIG. 7, when the line shaft 24 of the corresponding transfer device 22 rotates, each of the first transfer members 58 located below the roller conveying surface of the first conveyor 12 is driven by the driven gear. The steel material 10 is raised in parallel while maintaining the horizontal posture through the row, and the protection member 58, 6
0 and picked up from the first conveyor 12. At this time, since the long steel material 10 is braked by the magnetic attraction force of the permanent magnet 62 built in the first transfer member 58, the long steel material 10 is picked up by the first transfer member 58 in the parallel state.

The first transfer member 58 includes a plurality of long steel materials 1.
After having risen to the top dead center in FIG. 8 with 0 being placed, it descends toward the roller transport surface of the second conveyor 16 in a horizontal posture. The fluid pressure cylinder 86 of the stripping device 20 includes:
Immediately before the first transfer member 58 approaches the roller conveying surface of the second conveyor 16, the peeling plate 79 is moved to an operating position where the peeling plate 79 projects in an inclined posture above the roller conveying surface. When the mounting surface of the first transfer member 58 is lowered to a position intersecting with the upper surface of the peeling plate 79, as shown in FIG. 9, first, the long steel material 10 on the inclined upper side (right end side in the figure) is peeled off.
9 is peeled off from the first transfer member 58 in contact with the upper surface of the transfer member 9.
Then, with the lowering of the first transfer member 58, the long steel 10
Are peeled off one by one and transferred to the upper surface of the peeling plate 79.

After the mounting surface of the first transfer member 58 moves below the roller conveying surface of the second conveyor 16, the fluid pressure cylinder 86 is reversely urged, and the peeling plate 79 moves to the retracted position. Thus, as shown in FIG. 10, the plurality of long steel materials 10 transferred to the peeling plate 79 are transferred to the second conveyor 16. With this, the long steel 10
Are sequentially transported to the downstream side of the transfer device 22 via the second conveyor 16. At this point, the second transfer member 6
0, as shown in FIG. 10, faces the roller below the roller conveyor surface of the first conveyor 12 in a horizontal posture, and waits for the next transfer of the long steel material 10.

That is, in the embodiment, the transfer members 58, 60
Since the long steel material 10 is magnetically attracted by the permanent magnet 62 incorporated in the second conveyor, the long steel material 10 traveling on the first conveyor 12 at high speed is transferred to the second conveyor 16 while maintaining the parallel posture. be able to. In addition, since all of the magnetically attracted long steel materials 10 are not peeled at one time, but are peeled one by one by the peeling plate 79 in the inclined posture, each long steel material 10 can be easily peeled off.
A large force can be prevented from being applied to the drive source or the like when peeling. Moreover, the transfer member 58,
Since it is gradually peeled from one end in the short direction to the other end without being peeled off at once from 60, it is easier to peel off and stable transfer is possible, and the posture at the time of this transfer Can be suitably prevented.

In the embodiment, a permanent magnet is used as a magnetic attraction means for applying braking to the long steel material. However, the long steel material having the maximum length and weight required by the specifications of the transfer device is used. An electromagnet that can adsorb and release the steel material by the destruction of the magnetic force can also be used. In the case of an electromagnet, the magnetic force can be adjusted according to the specifications of the long steel material. Further, in the embodiment, the transfer device is configured by the delivery device and the stripping device, but the stripping device can be omitted.

As a mechanism for moving the transfer member while maintaining the horizontal posture in the delivery device, a sprocket is provided for each of the driving gear and the operating gear without using a driven gear train as in the embodiment. However, even in a configuration in which an endless chain is wound between both sprockets, the same movement can be imparted to the transfer member. Further, a block motion may be applied to the transfer member using a parallel link mechanism. Further, the mechanism for swinging the peeling plates is not limited to the mechanism of the embodiment, and each peeling plate can be swung directly by the fluid pressure cylinder. Furthermore, a configuration in which a peeling plate having an inclined upper surface is vertically moved up and down by a fluid pressure cylinder can be adopted.

[0024]

As described above, according to the long steel material transfer apparatus according to the present invention, a large number of long steel materials traveling in parallel on a conveyor at high speed can be placed on adjacent mounting portions. In order to reduce the kinetic inertia by applying a magnetic attraction force to these many long steel materials traveling at high speed when transferring them to the high speed, stable transfer without breaking the parallel posture of the long steel materials Can be done. Further, since the plurality of long steel materials magnetically attracted to the transfer member are configured to be sequentially peeled one by one by the peeling member, resistance at the time of peeling the steel material is reduced, and more stable transfer can be achieved. .
