2. Description of the Related Art Conventionally, as a sorting apparatus suitable for sorting articles having different external shapes and sizes, a large number of slats are moved in a predetermined direction to transport articles placed on the slats, and a moving shoe. Are moved along the slats so that the articles on the slats are pressed at predetermined positions of the articles and discharged to the side in the transport direction to sort them.

In the moving shoe 70 of such a sorting device, as shown in FIG. 6, a slat (not shown) is used.
A cap portion 72 is fixed via a bolt 73 to the upper surface of a slide portion 71 slidably supported so as to surround the cap portion 72.
Presses the article on the slat. A guide pin 74 is provided on the lower surface of the slide portion 71, and a guide roller 75 is rotatably supported on the guide pin 74 in a horizontal state.

When an article is conveyed by the movement of the slat, the moving shoe 70 moves the guide pin 74 and the guide roller 75 along a guide rail (not shown) provided along the article conveying direction (left-right direction in the figure). And move with the slats in the transport direction of the article. The moving shoe 70 moves the guide pin 74 and the guide roller 75 at a predetermined position for each article toward a side of the article in the conveying direction (a direction perpendicular to the plane of the drawing) (a guide rail (not shown)). To slide the slide portion 71 along the slat. As the slide portion 71 slides, the cap portion 72 presses the articles on the slats, discharges them to the side in the transport direction, and sorts them.

In the moving shoe 30, as shown in FIG. 2, a cap portion 32 is detachably provided on an upper surface of a slide portion 31 slidably supported so as to surround the slat 20 (FIG. 1). The cap part 32 presses the article 10 (FIG. 1) on the slat 20 as the slide part 31 slides. A guide pin 33 is provided on the lower surface of the slide portion 31, and a guide roller 34 is rotatably supported on the guide pin 33 in a horizontal state.

When the article 10 is conveyed by the movement of the slat 20, the moving shoe 30 moves the guide pin 33 and the guide roller 34 on a guide rail (not shown) provided along the conveying direction A (FIG. 1). It is guided and moves in the transport direction A together with the slat 20. The moving shoe 30 moves the path of the guide pin 33 and the guide roller 34 at a predetermined position for each article 10 by a divert unit 40 (FIG. 3) described later toward a guide rail ( (Not shown). Thereby, the moving shoe 30
Moves by sliding the slide portion 31 along the slat 20 in a direction perpendicular to the plane of the paper of FIG. Along with the movement, the cap portion 32 presses the articles 10 and discharges them to the side in the transport direction A to sort them.

The cap portion 32 slides by causing an iron plate 35 provided on the bottom surface to be attracted to an iron plate 36 provided at an opposing position on the upper surface of the slide portion 31 by the magnetic action of a flat permanent magnet 37. The unit 31 is provided so as to be separable. The permanent magnet 37 is mounted on the slide section 31.
