The controller 400 can easily confirm It is preferable that the worker is installed on one side of the support part 100 in which the operator is located.

The operation of the tire groove carving apparatus constructed as above will be described below.

14 to 18, a smooth tire T for engraving a groove is coupled to the support portion 100, and a conveying means 270 is provided to allow the carving machine 250 to engrave the groove along the pattern design, The transport body 240 is transported to one side of the smooth tire T with the tracing paper attached thereto and the angle of the carving machine 250 is adjusted through the angle adjusting means 290 after the transporting body 240 is transported. So that the carving blade 251 is perpendicular to the pattern to be carved.

Here, the tracing paper may be attached to the rotating tire 120 before the rotating tire 120 is joined to the rotating body 120, or may be attached after the rotating tire 120 is coupled to the rotating body 120.

In order to make the position of the conveying body 240 at this time coincide with the position of the groove conveyed through the numerical guide part 221 and the position of the numerical identification part 245 and the lower surface of the carving machine 250 It is preferable that the center portions of the combined carving edges 251 are aligned with each other.

When the conveying body 240 is completely conveyed to the position where the groove is to be formed, the conveying unit 200 is rotated until the carving machine 250 is brought into contact with the outer surface of the smooth tire T via the rotation force supplying means 320 When the carving machine 250 is brought into contact with the outer surface of the smooth tire T, the smooth tire T is rotated at a low speed and the transporting part 200 is further rotated to engage with the lower surface of the carving machine 250 Thereby allowing the carving blade 251 to be inserted into the smooth tire T.

This is to allow the carving blade 251 to be easily inserted into the smooth tire T and start carving with the carving blade 251 inserted to obtain a clean and accurate carving surface. The surface of the smooth tire T which is generated when the smooth tire T is brought into contact with the carving blade 251 when the smooth tire T rotates is torn and the accurate groove And the carving machine 250 and the carving blade 251 are damaged.

In the carving machine 250, heat is applied to the contact surface of the smooth tire T and the carving blade 251 during the carving operation. This is because the carving machine 250 is attached to the hard smooth tire T, So that the contact surface is changed smoothly so that the carving blade 251 can be easily moved. Thus, the formed portion of the groove can be easily and easily carved, and the carving blade 251 can be cleanly and accurately carved.

When the size of the wheel W is changed, it is difficult to insert the carving blade 251 into the smooth tire T even when the conveying unit 200 is rotated, or when the carving blade 251 is not smoothly inserted into the smooth tire T, The carving machine 250 may not touch the outer surface of the smooth tire T. At this time, the heat generated through the hot wire of the carving machine 250 may not be transmitted to the smooth tire T So that the outer surface of the smooth tire T is sculpted in a state of being hard, so that it is impossible to easily and precisely cut the groove.

Particularly, the carving blade 251, which is installed according to the depth of the groove, is formed so that the carving machine 250 is in contact with the outer surface of the smooth tire T When the carving operation is performed in a state where the carving machine 250 is separated from the smooth tire T, it is impossible to precisely cut the groove according to the pattern design. Therefore, in order to prevent the above problems, 243 to allow the distance between the carving machine 250 and the upper body 241 to be adjusted.

Accordingly, the transfer body 240 further includes a control valve 243 for controlling the distance that the carving machine 250 is separated from the transfer body 240, that is, the upper body 241, The carving machine 250 can be adjusted so as to be perpendicular to the smooth tire T so that the carving blade 251 can be easily inserted into the outer surface of the smooth tire T, And the generated heat is transferred to the engraved surface of the smooth tire T, which is advantageous in that a uniform and precise carving operation can be performed.

The carving machine 250 is brought into contact with the outer surface of the smooth tire T through the rotation of the feeder 200 and the carving blade 251 is rotated by the rotation of the feeder 200 and the rotating body 120 The fixing piece 312 is inserted into the protruding piece 311 formed on the outer surface of the connecting joint 211 so that the rotating state of the transporting unit 200 is maintained.

The protruding piece 311 is formed in such a manner that the carving machine 250 is brought into contact with the smooth tire T The conveying unit 200 that is rotated through the rotating force supplying unit 320 is smoothly rotated toward the smooth tire T so that the conveying unit 200 is fixed at the set position and is not rotated in the opposite direction So that the carving machine 250 and the smooth tire T can be kept in contact with each other.

When the carving machine 250 is brought into contact with the smooth tire T and the rotation of the feeder 200 is fixed by the fixing means 310, the rotation motor 110 is driven and the rotation motor 110 So that the recognition of the pattern design through the sensing means 280 and the movement of the transfer body 240 through the transfer means 270 can be performed at the same time while the smooth tire T is rotated, The groove can be uniformly sculptured.

At this time, in order to engrave the straight groove, the carving machine 250 is brought into contact with the smooth tire T according to the pattern design, and then the rotation of the carving machine 250 through the angle adjusting means 290 is stopped When the smooth tire T is rotated through the rotation motor 110, the carving operation of one linear groove is completed.
