Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cargo loading device for a pivoted bucket conveyor having a large number of buckets that are installed at equal pitches between two endless conveyor chains so as to be able to fall over. .

The conventional technology pivoted bucket conveyor is horizontal, as shown in Figure 1.
It circulates endlessly in the direction of the arrow along a vertical or inclined path, throws the transported object into the bucket at position A on the lower horizontal path, raises it vertically or inclined to a higher place, shifts to horizontal again, and transfers it to the upper horizontal section. At an arbitrary position, the objects in the bucket are completely discharged to the discharge port by the bucket overturning means B, and the objects are transported both horizontally and vertically. When loading into the bucket, wrap parts LI+L2 are provided at the front and rear ends of the bucket to prevent the transported material from leaking from the gap between the leading bucket (V+) and the following bucket (V2), which overlap each other. 4
When the bucket transitions from horizontal operation to vertical operation as shown in figure (al), if the trailing end lap portion Ll of the preceding bucket is below the front end lap portion L2 of the following bucket V2, the wrapping of the preceding bucket Vl Since the ramp part cannot maintain a horizontal position due to interference from the lap part L2 of the succeeding bucket V2, it is necessary to install a lap changer Rc at the required location to reverse the weight of the ramp part, as shown in Figure 4 (bl). This complicates the structure of the bucket and conveyor.

Problems to be Solved by the Invention The present invention eliminates the need to provide wrap portions at the front and rear ends of the bucket.
This prevents the loaded items from leaking through the gaps between the buckets when the items are thrown into the buckets.

Means for Solving the Problems The present invention provides a pivoted bucket conveyor equipped with buckets without wraps, which is located at the load input position on the horizontal path of the conveyor, and which is fixed to a driven sprocket that meshes with the chain of the conveyor. a rotating supply drum provided therein; an input guide cylinder that is fixedly attached to a transport material input chute and is housed in the drum, and has a lower end opened toward an inner circumferential surface of the drum;
The drum has an outer circumferential speed that is the same as the moving speed of the chain, and the pivoted bucket conveyor is provided with transport discharge openings having the same pitch as the mounting pitch of the pivoted buckets on the circumferential surface of the drum. This is a transport loading device.

The sprocket that meshes with the conveyor chain to which the bucket is attached rotates the outer peripheral speed of the rotating supply drum equal to the running speed of the chain, so that the movement of the bucket and the rotation of the conveyance discharge opening of the rotating supply drum are the same. Therefore, if the arrangement pitch of the plurality of cargo discharge openings provided on the circumferential surface of the drum is the same as the pitch of the installation of a large number of buckets attached to the chain, the cargo discharge openings will always be arranged at the same pitch. It rotates in line with the bucket directly above it.

Therefore, the transported material flowing down through the transported material input chute is released onto the inner circumferential surface of the rotary 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 rotary supply drum, and is placed between the buckets. When the gap is located directly below the rotary supply drum, the peripheral surface of the drum that does not have an opening faces the gap between the buckets, so that the transported articles in the rotary supply drum are not discharged.

In other words, the cargo inside the rotating supply drum is It will be intermittently injected only into Kerat.

Embodiment FIG. 2 is a front view of essential parts of an embodiment of the present invention, and FIG.
FIG. 1 is a side view of the pivoted bucket conveyor, in which chain 1 of the pivoted bucket conveyor has a plurality of adjacent buckets) V I + V
2 + V 3...The bucket in which the front and rear ends of Vn do not overlap each other is the pivot pin P L + P
2 + P 3... It is attached so that it can be tipped over at Pn.

Note that rollers R1, R2...Rn are fitted onto the link plate connecting pins of the chain 1, and the rollers R1, R2...
2...Rn is meshed with the teeth of sprocket 2,
There is a cam pin C on the side of each bucket for tipping the bucket.
1, C2...Cn are provided protrudingly.

One end of the rotating shaft 3 of the sprocket 2 is connected to the chain roller R1+ at the conveyance input position on the horizontal path of the conveyor.
R2...Rn travel guide rail G is installed on frame F.
An example of the rotating supply drum 5 is rotatably supported by a cantilever bearing on a frame 4, which has a circumferential surface having the same radius as the pitch circle radius r of the sprocket 2, and is fixed to the sprocket 2 concentrically with the sprocket. A loading guide tube 7 with an open side and having a load chute 6 for conveyed material is inserted into the drum 5 .

The charging guide cylinder 7 rotatably bears the free end of the rotating shaft 3 of the sprocket in the drum 5, and the lower end of the guide cylinder 7 at the front in the direction of rotation of the drum 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 crush objects, and the opening 8 is close to the inner peripheral surface of the drum.

Further, on the entire circumferential surface of the rotary supply drum 5, a plurality of conveyance discharge openings 9 are provided with a pitch equal to the pitch of the buckets on the chain 1, and furthermore, on the side surface of the input guide cylinder 7, A scraper plate 10 whose tip is in sliding contact with the inner circumferential surface of the drum is fixed to prevent the objects to be transported on the inner circumferential surface between the plurality of openings 9 of the drum 5 from being dragged upward as the drum rotates. .

Due to this force, the bucket throats Vl+V2...Vn and the opening of the rotary supply drum 5 always move at opposite timings, and the transported goods discharged from the discharge opening 9 of the rotary supply drum 5 fill the gap between the buckets. The material is reliably thrown into the bucket without being dropped.

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 and the peripheral surface rotation speed of the rotating supply drum are equal, and the attachment of the bucket is Since the pitch and the conveyance discharge opening pitch of the rotating supply drum are the same length, the conveyance discharge opening of the rotary supply drum always rotates opposite to the bucket,
When the transported material is discharged from the lower end opening of the input guide cylinder into the rotating supply drum from the transported material input chute and is discharged from the transported material discharge opening, there is always a bucket directly below the transported material discharge opening of the drum. Since there is a gap between the buckets facing each other directly below the drum circumferential surface that does not have a drum circumferential surface, that is, a drum circumferential surface that exists between a transported material discharge opening and an adjacent transported material discharge opening, there is a gap between the buckets. There is no risk that the cargo inside will be released.

The objects to be transported on the inner circumferential surface of the drum that are not released pass through the discharge position as the drum rotates.
The transported materials are returned to the subsequent transported material discharge opening and thrown into the bucket from this opening, so the transported materials supplied into the drum from the input chute are intermittently moved from the inside of the drum into the bucket according to the pitch of the bucket. It is ensured that it is thrown into the bucket and is not dropped out of the bucket.

In addition, the front of the lower end opening of the input guide cylinder in the direction of drum rotation is
Distance δ between the inner circumferential surface of the drum and the object to be transported so as not to crush it
Because of this, there is no deterioration in the quality of the transported items, and since the scraper is provided, the entire amount of transported items in the drum is thrown into the bucket without adhering to the inner circumferential surface of the drum.

As described above, the present invention has the advantage that even if the bucket is an extremely simple wrapper that does not require a complicated structure and operation such as the front and rear end type interlocking buckets that require a wrap changer, it is possible to prevent objects to be transported in the gap between the buckets. It has excellent features such as being able to reliably feed the material into the bucket without spilling it, and since the rotating supply drum is rotated using the movement of the chain as the driving force, there is no need to install a separate power supply device. It is effective.
