The support part 121 is connected to one end of the contact part 111 to support the contact part 111. In this embodiment, the support 121 is formed in a cylindrical shape. The first stopper 121a and the second stopper 121b are provided around the support 121.

The first stopper 121a is provided at one side of the support part 121 and is disposed in the first space 122b of the housing 122 partitioned by the partition wall 122a. Since the outer diameter of the first stopper 121a coincides with the inner diameter of the housing 122 constituting the first space 122b, the support 121 is made without moving in the housing 122.

3 to 6, the first stopper 121a is excessively moved when the support 121 moved to the housing 122 is restored by the elastic member 123 (FIG. 6). To prevent the housing 122 from leaving. That is, the support 121 returned by the elastic member 123 is stopped when the first stopper 121a comes into contact with one surface of the first space 122b.

The second stopper 121b is provided at the tee side of the support part 121 and is disposed in the second space 122c of the housing 122 partitioned by the partition wall 122a. The outer diameter of the second stopper 121b coincides with the inner diameter of the housing 122 constituting the second space 122c. Therefore, the support part 121 is made to move in the housing 122 without shaking by the first stopper 121a and the second stopper 121b.

As described above, the inner diameter of the housing 122 constituting the first space 122b is the same as the outer diameter of the first stopper 121a, and the inner diameter of the housing 122 constituting the second space 122c is also the second stopper ( Since it is the same as 121b), the support part 121 can move up and down without shaking in the housing 122.

One end of the elastic member 123 is connected to the first stopper 121a, and the other end is connected to the partition wall 122a. Therefore, when the contact part 111 is in contact with the material S, the support part 121 moved in a direction away from the material S is released by the elastic member 123 when contact between the contact part 111 and the material S is released. It returns to its original position.

That is, the elastic member 123 provides a restoring force to win position the support 121 when the contact between the contact portion 111 and the material S is released and the external force for pressing the contact portion 111 and the support 121 disappears. . In the present embodiment, the elastic member 123 is a spring coil, and is illustrated as a shape surrounding the circumference of the support 121.

The metal body 124 is provided at one end of the support part 121 and is located closer to the temperature measuring part 110 than the sensor part 125 provided in the housing 122. The sensor unit 125 detects when the metal body 124 reaches the same horizontal position as the sensor unit 125 when the support unit 121 moves.

The controller (not shown) starts the temperature measurement by operating the temperature measuring unit 110 based on the signal received from the sensor unit 125. The temperature measurement ends after the user specified time, for example 5 seconds if the user specifies 5 seconds.

The sensor unit 125 is provided in the second space 122c of the housing 122 to sense the movement of the support unit 121. The sensor unit 125 includes a limit sensor. When the metal body 124 moves to the same horizontal position as the sensor unit 125, the sensor unit 125 detects this and transmits an arrival signal to the control unit.

With reference to the drawings will be described the operation principle of the side guide device according to an embodiment of the present invention.

After the raw material S is extracted from the heating furnace, the raw material S is transferred by the feed roller part 10 to reach the parallel guide part 21. The feed roller unit 10 temporarily stops the transfer operation when the raw material S reaches the parallel guide portion 21. At this time, the parallel guide portion 21 adjusts the material S to the center C by reflecting the degree of departure of the material S from the center C.
