And a moving mechanism 5 for moving the block 4 in the vertical direction, and a block 4 sliding in the opening 3 extending in the lower part of the hopper 1 in the vertical direction. Each device is mounted on a base 6. .

A frame 21 of the belt conveyor 2 is erected on the base 6, and a hopper 1 supported by a support member 7 on the base 6 is attached to a lower portion of the frame 21. Further, the base 6 is provided with legs 8 whose length can be adjusted. As shown in FIG. 7, the cap W is in the shape of a crown or a cylinder with a bottom, is made of a magnetic material such as metal, and has a flat surface and a back surface having a peripheral edge portion that is capped on the head of a bottle or the like. Have.

The belt conveyor 2 includes rollers 22 and 23 attached to the upper and lower ends of the frame 21, a belt 24 wound around the rollers 22 and 23, a motor 25 for rotating the roller 23 to rotate and move the belt 24, A magnet 27 is provided on the back side of the belt 24 on the hopper side with a carrier plate 26 interposed, and a protective frame 29 is provided on both sides of the belt conveyor 2 above the hopper 1 and on the return path 28. The driving force of the motor 25 is transmitted by a pulley belt 32 that is wound around a pulley 30 on the motor 25 side and a pulley 31 on the roller 23 side, and the motor 25 is explosion proof.

A sorting mechanism for sorting the front and back of the cap W is provided above the belt conveyor 2. This sorting mechanism moves from the passage 35 to the next step only when the front surface of the cap W located on the sorting path 34 by the guide 33 is on the conveying plate 26 side, and when the back surface is on the conveying plate 26 side. Since the surface side of the cap W is heavier, it falls from the sorting path 34 and is returned to the inside of the hopper 1 through the return path 28.

As shown in FIGS. 3 and 4, the bottom surface of the hopper 1 is inclined toward the belt 24 so that the cap W gathers on the belt 24, and the belt 24 is located on the side surface of the hopper 1. Has become. The opening 3 is extended so as to project downward from the bottom of the hopper 1 which is close to the belt 24, and the block 4 is formed so that the block 4 can slide in the vertical direction. The upper surface of the block 4 is inclined toward the belt 24 side, and the block 41 has a V-shaped inclination as shown in FIG. 5 and the block 42 has a simple inclination as shown in FIG.
