Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field to which the Invention Pertains] The present invention relates to a billet conveying device for a billet heater that is capable of conveying a certain amount of billets at once.

[Prior art and its problems]

In billet unloading devices for billet heaters that transport a fixed amount of billets in bulk, a billet stopper is generally provided at the unloading port to control the unloading amount, and the shooter is connected so that it can be tilted forward and downward from the horizontal direction. The structure has a disadvantage in that the starting angle at which the billet begins to slide on the shooter is not constant, making it difficult to continuously transport a fixed amount of billet.

[Purpose of the invention]

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned drawbacks, it is an object of the present invention to provide a billet delivery device for a billet heater that can reliably transport a certain amount of billets in one go.

[Key points of the invention]

According to the present invention, such a purpose is achieved by providing a billet heater connected to a carrier at the billet outlet of the billet heater so as to be able to tilt forward and downward from the horizontal direction, and to collect a plurality of billets transferred from the carrier at the billet outlet. a first stopper which is provided at the tip of the shooter and is capable of entering and exiting the billet transfer path of the shooter; When a plurality of predetermined amount of billets are placed on the shooter in contact with the first stopper,
a second stopper that presses the billet on the conveyance table to stop the transfer of the billet; the billet comes into contact with the first stopper, and a plurality of predetermined amount of billets are placed on the shooter. At this time, the second stopper is actuated to stop the transfer of the billet on the conveyance table, and the shooter is tilted, and when the shooter is tilted by a predetermined angle, the first stopper is moved out of the billet transfer path of the shooter. This is achieved by transmitting the billet on the shooter and the shooter.

[Embodiments of the invention]

FIG. 1 shows an embodiment of the present invention, in which a shutter 4 is installed horizontally at the end (export port) of a conveyance table 3 for a metal billet 2 passing through the center of an induction heating coil 1 wound in a cylindrical shape. It is connected so that it can tilt from the front down. The high-temperature billet 2 heated by the electromagnetic induction effect of the coil 1 is continuously conveyed on the conveyor table 3, and when a certain amount of the billet 2 is transferred onto the shooter 4, the billet 2 at the outlet is pressed down to reduce the amount of conveyance. A piston-shaped stopper 5 that controls the transport platform 3
provided at the end of the The shooter 4 can be tilted by the action of the cylinder 6 to a position where it communicates with a fixed shooter 7 arranged at an angle as shown in FIG. It is provided so that the position in the direction can be adjusted. The shooter 4 has a U-shaped cross section, and is provided with a cover 9 on the top to prevent the billet 2 from falling off the shooter 4 or changing its posture when it slides down a slope. The cover 9 and shutter 4 may be integrally formed into a cylindrical shape.

According to the embodiment, the stopper 8 is first projected into the shooter 4 to transfer a certain amount of the billet 2 from the carrier 3 onto the shooter 4, and then the billet 2 at the end of the carrier 3 is held down by the stopper 5. Shooter 4
When the stopper 8 is released after tilting the billet so that it communicates with the fixed shooter 7, the billet 2 on the shooter 4 slides smoothly and continuously under its own weight, and is securely removed from the fixed shooter 7 as shown in FIG. It can be transported to

In the above embodiment, the case where the stopper 5 is provided at the end of the conveyance table 3 has been explained, but the stopper 5 is omitted in the case where a fixed amount of billet 2 is transferred from the conveyance table 3 onto the shooter 4 at a constant tact. You can also. In addition, the shooter 4 may be of a fixed type that is tilted forward and downward, as long as the billet 2 does not change its posture when it slides.

〔Effect of the invention〕

According to this invention, in the billet unloading device for a billet heater, a shutter is tiltably connected to the billet unloading port, and a billet stopper is provided at the tip of the shutter so as to be able to control the unloading, so that a fixed amount of billets can be reliably delivered. This has the advantage of being able to be carried out in bulk.

Claims (1)

[Scope of Claims] 1. A billet heater 1 connected to a carrier 3 at the billet outlet of the billet heater 1 and provided so as to be tiltable forward and downward from the horizontal direction, on which a plurality of billets transferred from the carrier 3 of the billet outlet are loaded. a first stopper 8 provided at the tip of the shooter and capable of entering and exiting the billet transfer path of the shooter; When a plurality of predetermined amount of billets are placed on the shooter in contact with the first stopper,
a second stopper 5 for pressing down the billets on the conveyance table 3 to stop the transfer of the billets; the billets abut against the first stopper and a plurality of predetermined amount of billets are placed on the shooter; When the shutter is tilted by a predetermined angle, the second stopper is operated to stop the transfer of the billet on the conveyance table 3, and the shutter is tilted, and when the shutter is tilted by a predetermined angle, the first stopper is moved to the billet transfer path of the shutter. A billet delivery device for a billet heater, characterized in that the billet on the shooter is sent out from the shooter.
