That is, the vertical cylinder 141 and the horizontal cylinder (with the sensors 133 and 136 for detecting whether the crawler roller 20 is present in the inlet 140 on the bottom end of the rear end of the inlet 140). The operating state of the 142 can be controlled.

As described above, since the push rod 145 or the push member 146 of the inlet portion 140 moves up and down, the feed roller 20 is moved by the push rod 145 or the push member 146. This can be prevented and can move forward and backward so that the crawler roller 20 can be supplied into the heating unit 160.

On the other hand, as shown in Figure 9, the push member 146 fixed to one end of the push rod 145, the departure prevention portion 146b for preventing the crawler roller 20 from escaping from the push member 146 ) May be formed. Here, the departure preventing part 146b may be formed in contact with at least two locations with the outer diameter of the crawler roller 20. Thus, the push member 146 may supply or push the crawler roller 20 to the heating unit 160 while the push member 146 surrounds the crawler roller 20. For example, the departure preventing part 146b is formed in a triangular shape and the crawler roller 20 is positioned between the sides of the triangle, so that the crawler roller 20 leaves the push member 146. Can be prevented.

In addition, an elastic member 146a may be formed at the tip of the release preventing part 146b to prevent contact impact with the crawler roller 20. By providing the elastic member 146a, a constant friction force is generated between the push member 146 and the outer surface of the crawler roller 20, so that the crawler roller 20 is moved during the transport of the crawler roller 20. Slip in the push member 146 can be prevented.

10 and 11 are perspective views showing the operation of the lead portion of the manufacturing apparatus according to FIG. 10 and 11, the lead-out unit 180 is connected to the frame 190, a cylinder 181 vertically installed on the frame 190, a cylinder 181 connected to the cylinder 181, and a piston 182.
