  First, for example, a hopper chute of the conveying means 5 is opened to cut a slag A that has been cut to a certain size and has a coating process of two or more layers on the surface from the guide pipe 51 into the accommodation hole 61a from above the rotary rotor 61. Transport. Next, the rotary rotor 61 is rotationally driven intermittently in accordance with the forging timing of the forging machine, thereby being sequentially accommodated in the accommodating holes 61a as shown in FIG. The posture is changed to the state. The slag A whose posture has been changed to the horizontal state is pushed into the material introduction port 4 one by one by the push rod 71 of the pushing means 7 from the rear of the rotary rotor 61. When the preceding A slag is pushed out from the forging station S side discharge port 8 by the following slag A pushed by the pushing means 7, the preceding A slag is brought into contact with the stopper 9 and stopped and simultaneously held by the slag chucker 12. The

At the moment when the preceding slag A hits the stopper 9, the lock cam 16 of the guide block retracting means 15 is swung to lock the succeeding slag A by the lock cam 16 and the guide block 13 and at the same time against the spring 14, the guide block. 13 is retracted several millimeters (for example, 1 mm) together with the following slags A ... A, and a gap is provided between the preceding slag A and the following slag A. Then, at the timing when the guide block 13 retracts the subsequent slag A by several mm, the slag chucker 12 is moved laterally to transfer the preceding slag A to the forging part. Thus, when the slag A supplied from the material introduction port 4 side to the discharge port 8 on the forging station side is sandwiched by the slag chucker 12 and transferred to the forging part side, a large frictional resistance is applied to both end surfaces of the slag A. In addition, it is possible to reliably prevent peeling of the film on both end surfaces of the slag subjected to the film treatment and to perform smooth transfer.
In addition, the slag A transferred to the forging part side is forged into a predetermined shape by a die and a punch at each forging station S as usual at the transfer position.

  In the above-described embodiment, a rotary rotor type having the rotary rotor 61 that receives the slag A conveyed in the vertical posture by the conveying means 5 and changes the posture in the horizontal direction between the material introduction port 4 and the pushing means 7. Since the posture changing means 6 is provided, the slag A transported in the vertical posture can be easily and smoothly transported by the conveying means 5 in the vertical posture, while the slag A transported in the vertical posture is rotated by the rotary rotor type posture changing means 6. This is preferable because the posture can be changed in the horizontal direction and only one slag can be supplied to the material inlet 4 in an orderly manner.

  In forming a slag A made of titanium alloy that has been cut to a certain size and has two or more layers coated on the surface, the slag A has burrs that occur during cutting and particle peeling of the cut surface. As shown in FIG. 4, the end face processing of both ends of the cutting slag is performed by the end face correction punch 21 and the die 22, and the weight of the slag is also set by the guardner 23 on the fracture surface of the cutting slag as shown in FIG. This is best done with a grinding finish.

  Moreover, although the above embodiment demonstrated what applied the slag supply apparatus 1 of this invention to the forging machine, it is not limited only to a forging machine, It is to the apparatus similar to a forging machine, etc. It can be widely applied as a slag supply device.
