Further, the notch portion 44 (54) of the cover member 4 (5) provided so as to cover the conveyance groove 21 (31) is similarly twisted, and is conveyed by the notch portion 44 (54). The opening portion 21d (31d) of the conveyance groove 21 (31) is continuously formed at all positions in the direction, and a part of the conveyance groove 21 (31) can be confirmed at any position.

The mutual positional relationship between the respective transfer grooves 21A to 21E (31A to 31E) at the above A-A to E-E positions is schematically shown in Fig. 7. Hereinafter, the description will be made using FIG. 7 with reference to FIG. 4.

The conveyance groove 21A in the A-A position is formed on the flat upper surface 22 (32), and the curved surface portion 24 (34) is formed starting from the ridgeline at the upper left portion of the conveyance groove 21A in the drawing.

Further, the curved surface portion 24 (34) forms one portion of the cylindrical surface having the same rotation center O. However, according to the positional relationship between the curved surface portion 24 (34) and the upper surface 22 (32) and the side surface 23 (33) described above, the central angle of the curved surface portion 24 (34) is smaller than 90°.

As shown in Fig. 5, the inner surface shape of the covering member 4 (5) is formed in accordance with the outer shape of the guiding member 2 (3) formed as described above. As described above, the straight portion 21a (31a) near the start end of the conveyance groove 21 (31) is formed on the upper surface 22 (32) of the guide member 2 (3) as a flat portion, and the straight portion 21b near the terminal end ( 31b) is formed on the side surface 23 (33) of the guiding member 2 (3) as a flat portion. Therefore, the inner surface portions of the covering members 4 (5) which are formed by the straight portions 21a (31a) and 21b (31b) formed at the start end and the vicinity of the end of the conveyance groove 21 (31) are also formed as flat portions. The inner upper surface 41 (51) and the inner side surface 42 (52).

The dimensional relationship of the above portion is schematically shown in Fig. 8 by taking the case of the conveyance groove 21E (31E) in the vicinity of the terminal in Fig. 7 as an example. As can be understood from the figure, when the inner surface of the covering member 4 (5) covering the conveyance groove 21E (31E) is a curved surface, the conveyance groove 21E (31E) is caused between the conveyance groove 21E (31E) and the workpiece 8 conveyed therein. The gap becomes larger. On the other hand, when the inner surface of the covering member 4 (5) which covers the conveyance tank 21E (31E) is planar, the gap can be reduced by the amount of δ shown in the figure. Therefore, even in the case where the workpiece 8 which is easily unstable due to the shape, size, and weight and which is easily rotated inside the conveyance groove 21E (31E) is conveyed, the posture of the workpiece 8 can be appropriately maintained.

The workpiece posture changing device 1 configured as described above may be as follows The posture is changed while the workpiece 8 is being conveyed.

Therefore, even if the workpiece 8 is not pressed in order from the conveyance alignment means 9 toward the workpiece posture changing device 1, the workpiece 8 can be directly thrust in the workpiece posture changing device 1, so that the workpiece 8 can be smoothly conveyed.

Further, in the second embodiment, as shown in FIG. 2, the center position of the conveyance grooves 21 and 31 is only shifted toward the downward direction and is not formed in the upward direction. The brake force is not applied to the workpiece 8 conveyed inside the conveyance grooves 21 and 31, and the conveyance can be performed more smoothly.

The workpiece 8 can be finished by passing through the inside of the carrying grooves 21, 31 described above. Into the posture transformation. Specifically, by passing the starting end to the end of each of the transporting grooves 21, 31, the respective workpieces 8 can be rotated around the axis of the axis with the carrying direction to change the 90° posture, and by continuously passing By a conveyance path formed by connecting the two conveyance grooves 21 and 31 of the first guide member 2 and the second guide member 3, the total 180° posture can be changed. At this time, in each of the conveyance grooves 21 and 31, since the opening direction is only shifted from the upper side in the horizontal direction and does not turn downward, the workpiece 8 can be stably supported inside the conveyance grooves 21 and 31. Therefore, since the behavior of the workpiece 8 during transportation is stabilized and the inner surfaces of the covering members 4 and 5 are not excessively contacted, the conveyance of the workpiece 8 and the posture change can be smoothly performed without causing defects such as clogging. Further, even in the case where clogging occurs, in order to remove the workpiece 8 which is the cause of the clogging, the workpiece 8 can be stably supported inside the conveyance grooves 21 and 31 even when the cover members 4 and 5 are removed. Since the workpiece 8 does not fly out from the conveyance tanks 21 and 31, the maintenance work can be performed efficiently, the time for recovery can be shortened, and the man-hour can be reduced.

The portion does not create a force other than the direction of conveyance of the workpiece 8. Therefore, even in the above-described joint portion, a step caused by machining accuracy and mounting error occurs, and work is performed. When the piece 8 passes the step, the movement of the workpiece 8 does not cause instability, and the conveyance can be performed more smoothly. In addition, the inner surface is smoothly continuous between the end 21b of the conveyance groove 21 on the upstream side of the "connection portion between the guide members 2, 3" and the start end 31a of the conveyance groove 31 on the downstream side. Therefore, the clogging of the workpiece 8 occurs inside because the behavior of the workpiece 8 becomes unstable during the conveyance path.
