A support frame 12 is placed on the top of the box-like frame 5. This support frame 12 is formed in a U-shaped cross section with an open upper part, and is capable of supporting a box-shaped bucket 13 inside thereof. The support frame 12 also includes an end stopper 14 that abuts against the end surface of the bucket 13 on the side of the tank 3 to position it, a side stopper 15 that regulates the position of both sides of the bucket 13, and a support that can support the bottom of the bucket 13. It has a member 16. Brackets 17 inclined in the direction of the inclined frame 7 are provided on both sides of the support frame 12, and the brackets 17 have upper edge stops 18 that can abut on the upper edge of the bucket 13.
is provided at a distance from the bucket 13.

A first guide rail 8 is provided at the bottom of the support frame 12.
A first guide roller 19 is provided which is guided by. Further, at a position above the first guide roller 19 in the support frame 12 and close to the tank 3, a second guide roller guided by the second guide rail 9 is provided.
A guide roller 20 is provided.

21 is a drive device for raising and lowering the support frame 12 along the inclined frame 7. That is, sprockets 22 and 23 are provided at the upper and lower end positions of the inclined frame 7, respectively, and both sprockets 2
Both ends of the cable body 24 hung on the cables 2 and 23 are connected to the support frame 12 at the position of the first guide roller 19. Reference numeral 15 denotes a motor which transmits lifting power to the cable body 24 by rotating the sprocket 22.

In such a configuration, the bucket 13 containing objects to be transported such as powder or granules is carried onto the box-shaped frame 5 from the left side of the trolley 2 in FIG. Moved support frame 1
2 and is brought into contact with the end face stopper 14 and positioned. Further, both sides of the bucket 13 are positioned by side stoppers 14 of the support frame 12.

The truck 2 travels along the rail 1 while supporting the bucket cart 13 in this manner. At this time, since the inverted U-shaped truck 2 runs overlying the mushroom-shaped cross-section rail 1, the engagement between these rails 1 and the truck 2 is ensured.
A stable running condition can be obtained. The truck 2 stops at a position corresponding to the input port 4 of the tank 3. Then, the drive device 21 is operated to raise the support frame 12 along the inclined frame 7. Then, the first and second guide rollers 19 and 20 are first guided by the inclined portions 10 of the first guide rail 8 and the second guide rail 9, so that the support frame 12 is secured to the bucket 13 by the support member 16 or the like. While supporting the robot, it is lifted halfway up while maintaining its original posture.

When the support frame 12 is further raised, the second guide roller 20 moves to the horizontal part 1 of the second guide rail 9.

Since the first guide roller 19 continues to rise along the first guide rail 8, the support frame 12 turns around the second guide roller 20 together with the bucket 13 and tilts toward the input port 4. Start (position A in Figure 1).

From this state, the first guide roller 19 further rises, and when it reaches the upper end position of the first guide rail 8, the support frame 12 tilts toward the input port 4 side with respect to the vertical line at position B, and the inside of the bucket 13 The conveyed object 26 is dropped into the input port 4. Further, at this time, the bucket 13 falls toward the input port 4 due to its own weight, and its bottom part separates from the support member 16, and its upper edge is supported by the upper edge stopper 18. As a result, the bucket 13 is placed in a substantially downward position, so that the objects 26 to be transported are completely supplied into the input port 4 without remaining in the bucket 13.

Once the falling and supplying of the transported objects is completed, the support frame 12 is lowered. Then, the tilted support frame 12 returns to its original position, and the bucket 13, which was supported by the upper edge stopper 18, returns to the support member 16.
It will be accepted by Once the support frame 12 has returned to the box-shaped frame 5 position, or while lowering the support frame 12, the cart 2 is started and moved from the side of the tank 3 to another position.

Effects of the Invention As described above, according to the present invention, it is possible to easily and reliably raise and lower the bucket between the conveyance path and the upper side of the input port, and to topple the bucket over the input port with a simple structure. Not only is this possible, but the conveyance path is made up of rails with a mushroom-shaped cross section, and the cart is formed in a U-shape that overlaps the rail, so the rail and cart can be reliably engaged.
