2, in a state in which the shaft 10 is supported by the mounting groove 220 of the mounting portion 200, the transferring portion 100 is positioned below the mounting portion 200, and the shaft (not shown) 10).

In this state, the jig 300 is also held below the shaft 10.

In this case, each of the mounting grooves 220 and each of the conveying grooves 120 are arranged to coincide with each other in the vertical direction. For example, a first transport groove is disposed below the first mounting groove, and a second transport groove is disposed below the second mounting groove.

3, in order to move the shaft, when the conveying body portion 110 of the conveying portion 100 is raised, the conveying body portion 110 and the placing body portion 210 are at the same height And in this case, the shaft 10 is simultaneously supported by the feed groove 120 and the mounting groove 220.

2, although the transfer unit 100 is located at the lower portion of the mounting unit 200, the position of the transfer unit 100 is slightly inconsistent in the left and right direction than the mounting unit, ) Does not interfere with the mounting portion even if it moves upward.

3, the transfer unit 100 is arranged above the mounting unit 200 and the shaft 10 is rotated by the upward movement of the transfer unit 100. As a result, ).

5, when the conveying unit 100 advances in the direction of the arrow, the shaft 10 is lifted by the conveying unit 100 and is advanced in the moving direction of the conveying unit 100 Position.

6, when the feeding unit 100 is lowered in this state and the feeding unit 100 is further lowered below the mounting unit 200, the shaft 10 is moved downward from the mounting unit 200 And is placed in the mounting groove 220.

Then, the downward conveying unit 100 returns to the original place through the backward process.

Therefore, in the process of FIGS. 2 and 6, the shaft 10 is moved by one space by the transfer unit 100. 2, the shaft 10 in the first mounting groove is supported by the first mounting groove and the first conveying groove as shown in Fig. 3 by the upward movement of the conveying unit 100, and as shown in Fig. 4, Is supported only by the first conveying groove by the further rise of the first conveying groove (100).

5, the first conveying grooves are located in the upper area of the second embedding grooves that are ahead of the first embedding grooves. In this state, as shown in Fig. 6, the conveying section 100 Is lowered and the transfer unit 100 is positioned below the station 200, the lowered shaft 10 is supported in the second stationary groove.

Then, the transporting unit 100 moves backward to return to the original position, and then repeats this process, so that the shaft 10 can be continuously transported.

7, when the shaft 10 is supported by the mounting groove 220, the jig 300 located at the lower portion of the area where the inspection unit 400 is located rises, The shaft 100 is lifted.

In this case, the first jig 310 and the second jig 320 simultaneously ascend and the height of the shaft 10 is adjusted by the central groove inspection unit 410, the outer-diameter groove inspection unit 420, , And adjusts the same as the operation height of the outer diameter checking unit 430.

In this state, the central groove inspection portion 410 enters inward from both sides of the shaft 10, and the outer-diameter groove inspection portion 420 moves in the outer peripheral direction of the shaft end. The inner diameter and the existence of the center groove 10a are inspected and measured by the first inspection probe 411 of the central groove inspection unit 410 and the outer diameter of the center groove 10a is measured and measured by the second inspection probe 421 of the outer diameter groove inspection unit 420, The presence and the outer diameter and the depth of the outer surface 422 are measured.

Then, as shown in Fig. 8, the outer diameter checking portion 430 moves downward, and the outer diameter of the shaft 10 can be measured. The inspection results by the central groove inspection unit 410, the outer diameter groove inspection unit 420 and the outer diameter inspection unit 430 described in FIGS. 7 and 8 are all transmitted to the control unit 600.

The jig 300 supporting the shaft 10 is moved down so that the shaft 10 is mounted on the mounting groove 220 of the mounting portion 200 .

In this state, as shown in Figs. 2 to 6, the conveying section 100 performs the upward-forward-downward-backward movement to convey the shaft 10, and the shaft 10 following the shaft 10, The central groove 10a, the outer diameter groove 10b, and the outer diameter are measured and inspected by the inspection unit 300 after the upward movement of the jig 300.

However, when the shaft 10 is initially supplied, the right and left sides of the shaft 10 may be shifted.

In this case, the inspection result is transmitted from the inspection unit 400 to the control unit 600, and the control unit 600 determines whether the shaft 10 is in contact with the first jig 310 and the second jig 320, A second actuator 324 for driving the second jig 320 is provided with an additional command.

Therefore, as shown in Fig. 12, the second actuator 324 rises and the second jig 320 rises. Accordingly, the shaft 10 rises higher than the first jig 310. In this state, when the second actuator 324 rotates 180 degrees by the additional command of the controller 600, the second jig 320 also rotates, thereby changing both ends of the shaft 10.

When the second actuator 324 is lowered again, the second jig 320 and the shaft 10 are lowered and supported by the first jig 310. After returning to the height for inspection, The central groove 10a, the outer-diameter groove 10b, and the outer diameter can be measured and inspected by the sensor 400.

If it is determined that the product is good, it can be lowered at the inspection position and transported in the advancing direction by the transporting unit 100, as described above.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be appreciated that one embodiment is possible.

Accordingly, the true scope of the present invention should be determined by the technical idea of the claims.
