Move to. In this manner, by alternately rotating the body 62 by 180 degrees in different directions, the side panels M are successively and efficiently hung on the hanger 108 by the two holding members 30.

When the product holding member 30 rotates between the two positions S1 and S2, the holding member 30 is held in a backwardly inclined position, as shown by D in FIG. The radius of rotation when the product holding member 30 rotates around the center of the body 62 is
When the holding member 30 is in the attitude D shown by the solid line in FIG. 8, it is in the R2 shown in FIG. 12, and when the holding member 30 is in the attitude D shown in the chain line in FIG. 8, it is in the R1 shown in FIG. When R1<R2 and the product holding member 30 is held in the latter position, the rotation radius becomes smaller, and the entire device becomes more compact, and the side panel held by the holding member 30 becomes smaller. There is no risk that the side panel M will collide with surrounding obstacles, especially the side panel M already hung on the hanger 108, and the side panel M can be protected.

When hanging the left side panel M, the product holding member 30 rotates by 83 degrees about the horizontal axis. Therefore, the upper and lower edges of the side panel M that has reached the swing hanging position S2 are inclined by 7 degrees with respect to the vertical. In this state, the holding member 30 is rotated 90 degrees around the rotation axis 33c, so that the front and back surfaces of the side panel M are tilted 7 degrees with respect to the perpendicular line. Since the hanging rod 112 of the hanger 108 is inclined at 7 degrees with respect to the horizontal line as described above, the side panel M is hung on the hanging rod 112 with its surface perpendicular to the hanging rod 112.

When hanging the panel M on the right side, as shown in FIG. 21, the product holding member 30 is rotated by 97 degrees in the opposite direction to when hanging the panel M on the left side. Therefore, the right side panel M that has reached the hanging position S2 also has its upper and lower edges inclined by 7 degrees with respect to the perpendicular, similar to the left side panel.

By the way, when hanging the side panel M on the hanger 108, if the side panel M is hung in a vertical position on the hanger 108, as shown in FIG.
When the side panels M are hung on the hanging rod 112, the unevenness m of the two adjacent side panels M touch each other and do not fit into each other, and the distance between the side panels M increases, and the side panels M hung on the hanging rod 112
The number of will decrease. Further, the tip of the inclined hanging rod 112 is the highest. If the side panel M is horizontally translated in a vertical position and hung on the hanging rod 112, the highest end must be passed through, so the side panel M needs to be translated at its highest point, and then, When the side panel M is released and dropped, the hanging rod 1
There is a risk that the side panel M may be damaged due to the large drop up to 12.

However, as described above, when the side panel M is swung out by the product holding member 30, its surface is inclined with respect to the perpendicular line, so as shown in FIG. At that time, the unevenness m fit into each other, and then it assumes a vertical posture due to its own weight. Therefore, the distance between the side panels M can be narrowed, and a large number of side panels M can be hung from the hanging rod 112. Moreover, since the side panel M moves along the slope of the hanging rod 112, the drop of the side panel M when the holding is released is very small, and the side panel M will not be damaged.

A collar 143a is provided at one end of the coaxial shaft 143b, and a portion beyond the collar 143a is received by a bearing 153 attached to the lower end of the swing arm 140. At the other end of the coaxial portion 143b, a rectangular bar-shaped guide portion 143c having a width narrower than the outer diameter of the coaxial portion 143b is provided.
A movable cylinder 154 is fitted over the guide portion 143c from the coaxial portion 143b. Movable tube 1
54 has an end wall 154a, through which a guide portion 143c passes, and a compression coil spring 155 fitted in the guide portion 143c is interposed between the end wall 154a and the fitting shaft portion 143b. There is. An L-shaped pressing member 156 is attached to the tip of the guide portion 143c via a horizontal pin 157, and this pressing member 156 has a curved surface 156a and a handle 156b on both sides of the pin 157. .

With the curved surface 156a facing vertically downward, the curved surface 156a is in contact with the end surface of the movable tube 154, and the compression spring 155 is in a compressed state, and the spring force causes the tip of the movable tube 154 and the connecting member 143 to be compressed. Brim 1
43a clamps the stepped portion 152 of the short cylindrical body 144 from both sides, thereby achieving connection between the rotary plate 142 and the swing arm 140. As shown in FIG. 26, when the handle 156b is changed from the above-mentioned orientation to the sideways orientation, the movable barrel 154 is moved away from the short barrel 144 by the force of the spring 155, and the tip of the movable barrel 154 is moved away from the short barrel 144. Part Tsuba 1
It comes out of the short cylindrical body 144 together with 43a. In this state, if the fitting shaft portion 143b is pulled out from the short cylinder body 144 through the notch 151, the connection between the rotary plate 142 and the swing arm 140 is released.
