Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cargo input device for a pivoted bucket conveyor having a plurality of buckets installed at regular intervals between two endless conveyor chains so as to be able to fall over. It is.

PRIOR ART As shown in Fig. 1, a pivoted bucket conveyor endlessly circulates in the direction of the arrow along a horizontal, vertical or inclined path, and loads the transported goods into the bucket at position A on the lower horizontal path, then vertically or Raise it to a higher place on an incline,
The object is transferred horizontally again, and at any position on the upper horizontal part, the object to be transported in the bucket is completely discharged to the discharge port D by the bucket overturning means B, and is transported both horizontally and vertically. When loading cargo into the bucket in succession on the lower horizontal path, there is a mutual gap between the front and rear ends of the bucket to prevent the cargo from leaking through the gap between the leading bucket V ₁ and the next succeeding bucket V ₂ . However, when the bucket cart shifts from horizontal operation to vertical operation as shown in Fig. _4a , if the trailing end lap portion _L1 of the leading bucket truck overlaps with that of the following bucket truck _{V2 .} If the front end falls below the lap _L2 , the lap _L1 of the leading bucket _V1 will be interfered with by the lap _L2 of the trailing bucket _V2 and will not be able to maintain its horizontal position. As shown in b.
Since Rc must be installed at the required locations and the weight of the lap section must be reversed, the structure of the bucket and conveyor becomes complicated.

Problems to be Solved by the Invention The present invention does not provide wrap portions at the front and rear ends of the bucket, and prevents the loaded items from leaking from the gaps between the buckets when loading the items into the bucket. .

Means for Solving the Problems The present invention provides a driven sprocket which is disposed at the load input position on the horizontal path of a pivoted bucket conveyor equipped with a bucket without a lap part and meshes with the chain of the conveyor. a rotary supply drum fixedly attached to the transport material inputting chute, and an inputting guide cylinder fixedly attached to the transport material inputting chute and housed in the drum, the lower end of which is opened toward the inner circumferential surface of the drum; has the same peripheral speed as the moving speed of the chain, and the peripheral surface of the drum has:
This is a cargo input device for a pivoted bucket conveyor, in which drum peripheral walls and cargo discharge openings of the same pitch as the pivoted bucket openings are provided alternately.

Function The sprocket that meshes with the conveyor chain to which the bucket belt is attached rotates the outer peripheral speed of the rotating supply drum equal to the running speed of the chain, so the movement of the bucket belt and the rotation of the conveyance discharge opening of the rotating supply drum are the same. Because you can speed it up,
If the arrangement pitch of the plurality of cargo discharge openings provided on the circumferential surface of the drum is made the same as the opening pitch of the numerous buckets attached to the chain, the cargo discharge openings will always rotate so as to be directly above the buckets. do.

Therefore, the transported material flowing down by the transported material inputting chute is dropped onto the inner circumferential surface of the rotating supply drum from the lower end opening of the input guide cylinder, and is thrown into the bucket from the transported material discharge opening of the rotating supply drum. When the gap between the buckets is directly below the rotating supply drum, the peripheral wall of the drum that does not have an opening faces the gap between the buckets, so the transported material in the rotating supply drum is not discharged.

In other words, the objects to be transported in the rotating supply drum are only intermittently introduced into the bucket.

Embodiment FIG. 2 is a front view of essential parts of an embodiment of the present invention, and FIG.
The figure is a side view of Figure 2, and the chain 1 of the pivoted bucket conveyor has a plurality of adjacent buckets V ₁ , V ₂ , V ₃ . . . Bucket is pivoted pin P ₁ , P ₂ ,
P ₃ ...It is attached with Pn so that it can be tipped over.

Note that rollers R 1 , R ₂ ...Rn are fitted onto the link plate connecting pins of the chain 1, and the rollers R ₁ , R 2 .
Teeth of the sprocket 2 mesh with R ₁ , R _{2 . . . Rn, and cam pins C 1 ,} C ₂ .

One end of the rotating shaft 3 of the sprocket 2 is rotatably attached to a mount 4 provided on the mounting frame F of the traveling guide rail G of the chain rollers R ₁ , R ₂ . One side of the rotating supply drum 5 has a circumferential surface with the same radius as the pitch radius r of the sprocket 2, and is fixed to the sprocket 2 concentrically with the sprocket, while the other side is open and can be used to input the transported goods. Shoot 6
A charging guide cylinder 7 having a diameter is inserted into the drum 5 and housed therein.

The charging guide cylinder 7 rotatably bears the free end of the rotating shaft 3 of the sprocket within the drum 5, and the lower end of the guide cylinder 7 at the front in the drum rotation direction is connected to the inner circumferential surface of the drum 5 for transportation. An opening 8 is formed at the rear end of the drum in the rotational direction with an interval δ that does not damage the material, and the opening 8 is close to the inner circumferential surface of the drum.

Furthermore, the entire circumferential surface of the rotating supply drum 5 is alternately provided with conveyance discharge openings 9 having a pitch equal to the bucket opening pitch on the chain 1 and a peripheral wall of the drum having no openings. On the side surface of the guide cylinder 7, there is a scraper whose tip is slidably contacted with the inner circumferential surface of the drum so that the objects to be transported on the inner circumferential surface between the plurality of openings 9 of the drum 5 are not dragged upward with the rotation of the drum. 10 are fixedly installed.

Therefore, the buckets V ₁ , V ₂ . . . Vn and the opening of the rotating supply drum 5 always move at opposite timings, and the transported material discharged from the discharge opening 9 of the rotating supply drum 5 is transported through the gap between the buckets. It is ensured that it is thrown into the bucket without being released into the bucket.

Effects of the Invention In the present invention, since the pitch circle radius of the sprocket and the radius of the rotating supply drum are the same length, the horizontal running speed of the bucket belt and the peripheral surface rotation speed of the rotating supply drum are equal, and the opening of the bucket belt is the same. Since the pitch and the conveyance discharge opening pitch of the rotary supply drum are the same length, the conveyance discharge opening of the rotary supply drum always rotates in opposition to the bucket, and the conveyance discharge opening of the rotary supply drum always rotates in opposition to the conveyance feed chute and the lower end opening of the input guide cylinder. When the transported material discharged into the rotating supply drum is discharged from the transported material discharge opening, there is always a bucket directly below the opening, and the drum peripheral surface that does not have the transported material discharge opening, that is, the transported material discharge Since the gap between the buckets faces each other directly below the drum circumferential wall between the opening and the adjacent cargo discharge opening, there is no possibility that the cargo in the drum will be dropped into the gap.

The transported objects on the inner circumferential surface of the drum that are not released pass through the discharge position as the drum rotates, but are returned to the subsequent transported object discharge opening by the scraper plate 10 and enter the bucket from the opening. Therefore, the transported material supplied into the drum from the charging chute is intermittently thrown into the bucket from inside the drum in accordance with the opening pitch of the bucket, and is not dropped outside the bucket.

In addition, the lower end opening of the input guide tube has a distance δ from the inner circumferential surface of the drum at the front in the direction of rotation of the drum, so that the quality of the transported materials does not deteriorate. Since the scraper is provided, the entire amount of the transported material in the drum is thrown into the bucket without adhering to the inner peripheral surface of the drum.

As described above, the present invention prevents cargo from spilling into the gap between the buckets, even if the bucket is very simple and does not require a complicated structure and operation, such as a bucket with overlapping front and rear ends that requires a wrapper. Moreover, since the rotating supply drum is rotated using the movement of the chain as the driving force, it has excellent effects such as not requiring a separate power supply device. It is something.
