In these figures, 1 is a base, 2 is a hanger holding table provided at one end, and 3 is a horizontal transfer conveyor provided at the other end.

As shown in FIG. 3, the hanger 4 used in the present invention has a function of moving the movable arm 5 up and down in conjunction with opening and closing operations. The hanger 4 has a pair of opening and closing members 7 and 8 pivotally attached by pins 6, and the movable arm 5 is supported inside one of the opening and closing members 8 so as to be movable up and down. A lever 10 is pivotally attached to the protrusion 9 on the upper portion of the opening / closing body 8, and a roller 11 that is in contact with the opening / closing body 7 is provided at the tip of the lever 10. An elongated hole 12 is formed in the lever 10, and the upper end of the movable arm 5 is fitted in the elongated hole 12.

For this reason, as shown in FIG. 3A, when no external force is applied, the pair of opening / closing members 7 and 8 are closed by the force of the spring 13, and the upper end of the plate-like work W is clamped between the clamps 14 and 15. When the opening and closing members 7 and 8 are opened by an external force as shown in FIG. 3B, the roller 11 is pushed by the side surface of the opening and closing member 7 and the lever 10 rotates in the counterclockwise direction. Raised upward. Thereby, it becomes possible to insert and remove the plate-shaped work W from the lateral direction. Reference numeral 16 denotes a receiving groove provided at a lower portion of the hanger 4 and is a portion for holding a lower end of the plate-shaped work W. The receiving groove 16 is connected to the opening / closing body 7 by a side frame (not shown).

The hanger holder 2 can vertically support the hanger 4 described above. Further, the opening / closing body 8 of the hanger 4 is pushed on the upper portion of the hanger
An opening / closing mechanism 17 for opening the opening is provided. In this example, the opening and closing mechanism 17 is a cylinder, but any mechanism such as a rotating arm type can be used. The horizontal transfer conveyor 3 is a roller conveyor, and can transfer the plate-shaped work W in a horizontal posture as shown in FIG.

A carriage 18 is provided between the hanger holder 2 and the horizontal transfer conveyor 3. Trolley 1
An elevating frame 20 that is raised and lowered by an elevating cylinder 19 is provided on the top 8, and a horizontal shaft 22 is supported between bearings 21 at the upper end of the elevating frame 20. A bracket 24, which can be rotated 90 ° by a cylinder 23, is attached to the horizontal shaft 22. A work comprising a side support 25 for the plate-shaped work W and an end clamp 26 for the plate-shaped work W is mounted on the bracket 24. A clamp is provided.

As shown in FIG. 7, the bracket 24 is provided with a cylinder 27 for moving the side support 25 forward and backward. A rack gear is formed on the shaft of the side support 25 and the end clamp 26, and a pinion 28 is provided between them. Therefore, when the side support 25 is pushed out by the cylinder 27, the pinion 28 rotates clockwise to draw the end clamp 26.
