が残っていない。Next, the operation will be explained. The rolled steel plate 5 is conveyed on the table roller 1. In this case, in order to improve both the conveyance speed of the steel plate and the running stability, it is generally better to reduce the pitch of the table rollers as much as possible, but there is a limit to how small the pitch of the table rollers can be. Therefore, there is a demand for adding a linear motor to apply electromagnetic force such as propulsive force, suction force, tension, etc. to the steel plate, further improving the running stability of the steel plate, and realizing further improvement in conveyance speed. However, in the current table rollers, there is no space left between which a linear motor can be installed.

。Since the conventional device for conveying steel plates in a strip mill is configured as described above, improvement in the conveyance speed is limited by the pitch of the table rollers that can be implemented. Therefore, in order to add a linear motor and improve running stability using its electromagnetic force, it is necessary to increase the pitch of the table rollers in order to secure the installation space for the linear motor. When the size of the vehicle was enlarged, there were problems such as a decrease in driving stability.

モータを得ることを目的とする。This invention was made to solve the above-mentioned problem, and the table roller itself that conveys the steel plate is configured as a part of a linear motor, and it applies electromagnetic force such as propulsive force, suction force, tension, etc. to the steel plate. The object of the present invention is to obtain a linear motor that can improve the running stability of steel plates and also improve the limit on the increase in conveying speed.

機器の磁気ヨークと同様に、絶縁された薄鋼板を積層し
た構造とする。The table roller 2, which functions as the teeth of the linear motor, has a structure in which insulated thin steel discs are laminated in order to facilitate the passage of magnetic flux and reduce the loss generated therein. Three-phase alternating current is applied to the coil 3 to generate a traveling magnetic field. The magnetic yoke 4 has a structure in which insulated thin steel plates are laminated, similar to magnetic yokes of general electrical equipment.

The magnetic yoke 4 constitutes the primary side of a three-phase linear motor, and the steel plate 5, which is the material to be conveyed, becomes the secondary conductor of the linear motor, and thrust force is applied to the steel plate 5.

量が小さくても上記実施例と同様の効果を奏する。In addition, in the above embodiment, the coil is installed at a position lower than the table roller, but as shown in Figure 3, if the coil is installed between the table rollers, it is a little difficult to connect the coil end. On the other hand, since the generation of leakage magnetic flux can be reduced, even if the capacity of the linear motor is smaller than that of the above embodiment, the same effect as that of the above embodiment can be achieved.

がある。As described above, according to the present invention, the cable roller itself for conveying steel plates in a strip mill is constructed as a part of the linear motor, so there is no need to enlarge the pitch of the table roller to install the linear motor. Since the electromagnetic force such as the thrust, suction force, and tension of a linear motor can be added, it has the effect of reliably achieving better running stability than that obtained with the pitch of conventional table rollers.
