JPH0539111A - Carried material feeder for pivoted conveyer - Google Patents

Abstract

PURPOSE:To prevent carried materials from being dropped at any other position than a bucket when they are dropped directly from just above the bucket without using a carried material chuter provided with a device for diverting the feed direction of the carried materials. CONSTITUTION:In a carried materials feed position of a pivoted bucket conveyer, a carried material chuter 6 is installed at the upper part of an upper-stage feed side route (a), and between the upper-stage feed side route (a) and a lower- stage return side route (b), a clearance stuffing member 11 which rotates in a circular form while stuffing a clearance between buckets 4 at the lower-stage return side route (b) is provided. Even if the carried materials charged from the carried material chuter 6 are made to run over a clearance between the buckets 4 at the upper-stage feed side route (a), the clearance stuffing member 11 maintains a position where the clearance between the buckets at the lower- stage return side route (b) is covered and moves synchronously with the bucket 4, so all the carried materials are received by the bucket 4 on the lower-stage return side (b).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor for supplying a conveyed material for a pipeted conveyor.

[0002]

2. Description of the Related Art In a conventional pivoted conveyor, when a conveyed product is put into a bucket, a flange provided on each bucket is used to prevent the conveyed product from spilling between the buckets. It was designed to close the gap. However, since the flanges are provided when the bucket changes its moving direction, the flanges are often overlapped with each other to impair smooth bucket movement. In order to solve this point, a method of moving an empty bucket downward has been used. That is,
Conventionally, if a gap is provided between the buckets, the transported object will be spilled at the time of loading, and if a flange is provided to prevent this, this time, the bucket cannot be smoothly moved, which is a contradictory problem.

As a solution to these problems, there is one disclosed in Japanese Patent Laid-Open No. 63-197228. This transported material input device uses a rotating drum that allows the transported material to be loaded into each bucket without spilling the transported material from the gap between the buckets. This apparatus guides a conveyed product to the inside of a drum, and inputs the conveyed product into a bucket through a plurality of opening slits provided on the side surface of the drum. The drum is located at the top of the bucket, and the opening slits on the side of the drum are slightly narrower than the width of each bucket. The rotating speed of the drum and the moving speed of the bucket are synchronized so that the opening slit on the side surface of the drum facing downward and the opening of the bucket always correspond to each other. A spiral rod rotates coaxially with the rotary shaft of the drum at the rotary shaft. By the rotation of the spiral rod, the amount of the conveyed material in the drum is made uniform in the drum.

The manner in which the conveyed product is sent to the bucket by the conveyed product feeding device is as follows. A conveyed product is dropped onto the end of the rotating drum from a hopper provided on the upper side of one bottom surface of the drum. The dropped conveyed product is uniformly sent into the drum by the rotation of the spiral rod.
Then, when a plurality of opening slits provided on the drum come directly above the bucket, a conveyed product is put into the bucket through the opening slits.

[0005]

The above-mentioned conventional article feeding device has the following problems. That is, since the rotating drum is located right above the bucket, it is not possible to position the conveyed material supply unit such as the hopper directly above the bucket. For this reason, it is necessary to dispose a conveyed material supply unit such as a hopper on the side surface in the moving direction of the bucket. Therefore, in order to send the conveyed product from the conveyed product supply unit such as a hopper into the rotating drum, a conveying device such as a spiral rod must be attached and the conveying device must convey the conveyed product into the drum. As described above, there is a problem in that the device for changing the supply direction of the conveyed product uses the device for introducing the conveyed product, which requires a large space and is expensive.

An object of the present invention is to drop a conveyed product directly from directly above a bucket without using a conveyed product feeding device provided with a device for changing the supply direction of the conveyed product, and the dropped conveyed product is other than the bucket. The object of the present invention is to provide a conveyed material supply device configured to prevent spillage.

[0007]

In order to solve the above-mentioned problems, according to the present invention, a pair of return chains are individually attached to each other with a gap between adjacent buckets. At the conveyed product supply position where the upper feed side route and the lower return route route move in parallel in the vertical direction and in the opposite direction, the conveyed item feeder is provided above the upper feed side route, and the upper feed side route is connected to the upper feed side route. A feature is that a gap filling member that rotates in an annular shape is provided between the lower return paths and the gap between the buckets of the lower return paths is closed.

[0008]

Operation: The gap between the buckets on the lower return path is closed by the gap filling member. The gap filling member rotates in an annular shape while closing the gap between the buckets. As a result, even if a conveyed product dropped from the conveyed product feeder located directly above the upper feeding bucket falls over the gap between the upper feeding buckets, most of the conveyed goods are received by the lower return bucket and Even if there is a gap between the return-side buckets and a drop in the conveyed items, the lower-stage return-side buckets can catch the conveyed items. In this way, since all spills of the conveyed product from the upper-stage feeding side path are received by the lower-stage returning side, the conveyed product can be supplied without waste.

[0009]

1 and 2 show an embodiment of the present invention, showing the periphery of a conveyed material supply section on a horizontal movement path. A case 1 of the pipeted conveyor is provided with a pair of parallel sprockets 2. An annular chain 3 is hung on the pair of parallel sprockets 2 in parallel. In addition, a plurality of buckets 4 are pin 5 so as to be bridged between the chains 3.
Are mounted adjacent to each other in the moving direction of the chain 3. The bucket 4 has no flange and always moves upward. There is a gap between the individual buckets 4. The row of buckets 4 connected to each other is, in the horizontal movement path, an upper feed side path a and a lower return path b.
The two rows of are moving up and down in parallel. The upper feed path a and the lower return path b move in opposite directions.

A conveyed product input device 6 is installed above the upper feeding side route a of the bucket 4, and the conveyed product is dropped from the conveyed product inlet 7 into the bucket 4 of the upper feeding side route a. An enclosing member 8 is provided between the upper feeding side path a and the lower returning path b of the bucket 4. And this enclosure member 8
A gap filling device 9 is provided between the lower return path b and the lower return path b. The gap filling device 9 includes a unit cover 10, a plurality of rod-shaped gap filling members 11 each having a triangular cross section, sprockets 13 and 14, and a pair of annular chains 15.

The unit cover 10 is box-shaped and has openings on the upper feed side a and the lower return side b. A side portion 16 parallel to the bucket 4 is attached to the case 1 by a bolt (not shown). Further, the sprockets 13 and 14 and the chain 15 are combined in the same manner as the sprockets 2 and the chain 3 for moving the bucket 4,
It is provided in the unit cover 10. Then, one end of the shaft 12 of the sprocket 14 penetrates through the unit cover 10 and the case 1. A sprocket 17 is provided on a portion of the shaft 12 penetrating from the case 1. Also,
The plurality of gap filling members 11 are attached so as to bridge between the pair of chains 15. This pair of chains 15
The rotation of the above causes the gap filling member 11 to circulate like the bucket 4.

The power for driving the gap filling device 9 is obtained as follows. That is, sprocket 1
A shaft rod 18 that penetrates the side surface of the case 1 is provided under 7.
Sprockets 19 and 20 are provided on both sides of the shaft 18 with the case 1 in between. Case 1 of shaft 18
The sprocket 19 on the inner side of is engaged with the chain 3. The sprocket 20 on the outside of the case 1 is a chain.
The sprocket 17 is rotated via the engine 21. In other words, the driving force of the chain 3 is applied to the sprockets 19 and 20 and the chain.
It transmits to the sprocket 17 via the engine 21 and rotates the sprocket 14 coaxial with the sprocket 17 to drive the gap filling device 10. Since the gap filling device 10 receives power from the chain 3 in this way, the circulation speed of the gap filling device 10 and the moving speed of the chain 3 can be synchronized. A chain tensioner 22 keeps the tension of the chain 2 for driving the bucket 4 constant.

The combination of the gap filling member 11 and the chain 15 has the shape of an annular ladder. The rod-shaped gap-filling members 11 having a triangular cross section, which are mounted so as to span the pair of chains 15, are provided at equal intervals. At this time, the gap filling members 11 are opposed to each other with the pointed portion having a triangular cross section inside. Also,
The space between the gap filling members 11 is a space. The gap between the gap filling members 11 is equal from the gap of the bucket 4 on the lower return path b to the next gap. That is, the gap filling members 11 are arranged at intervals such that they are always positioned above the gap between the buckets 4 on the lower return path b. Further, since the gap between the gap filling member 11 and the bucket 4 on the lower return side b is moving in synchronization, the conveyed product spilled from the gap between the buckets 4 on the upper feed side route a is on the lower return route b. The gap filling member 11 on the bucket 4 is distributed and received by the buckets 4 on both sides below. Therefore, the conveyed product does not spill from the gap of the bucket 4 on the lower return path b. Then, when the sprocket 14 changes the rotation direction of the chain 15, the conveyed product that falls from the gap between the buckets 4 on the upper feed side a and rides on the upper gap filling member 11 is received by the buckets on the lower return side b. ..

The gap filling member 11 may have a plate shape or a semicylindrical cross section. When the gap filling member 11 having these shapes is used, first, the plate-like member returns to the lower stage when the sprocket wheels 13 and 14 change the rotation direction of the chain 15 respectively. It is received by the bucket on the side b. In the case of a semi-cylindrical section, the hemispherical portions are opposed to each other. By doing so, the transported articles dropped on the lower gap filling member 11 are not transferred to the bucket 4 on the lower return side b.
It is distributed to and accepted.

The operation of supplying a conveyed product by the above-described gap filling device 9 is as follows. That is, the conveyed product is introduced from the conveyed product introduction port 7 of the conveyed product introduction unit 6 into the bucket 4 on the upper-stage feeding-side path a immediately below the conveyed product introduction port 7. The buckets 4 on the upper feed path a that are continuously moving are always facing upward, and there is a gap between the buckets 4. Then, the conveyed product spills from the gap between the buckets 4.
The spilled transported material is stored in the bucket 4 of the upper feed path a.
And to the gap filling member 11 between the buckets 4 on the lower return path b. The gap filling member 11 is the lower return path b.
Since it is a member only attached to the chain 15 at an interval equal to the gap between the buckets 4 of No. 1, most of the spilled articles fall to the bucket 4 of the lower return path b. Then, the transported article that has fallen into the gap filling member 11 on the upper side is
The gap filling member 11 moves in the same direction as the bucket 4 on the upper feed side path a, passes through the sprocket 14, and is simultaneously dropped into the bucket 4 on the lower return path b. Further, the conveyed articles falling on the lower gap filling member 11 are sorted by the triangular pointed portions and received by the buckets 4 on both sides below. In other words, all the spilled products spilled from the gap between the buckets 4 on the upper-stage feed side path a fall on the bucket 4 on the lower-stage return side path b, and do not spill other than on the bucket 4.

[0016]

[Effect] The buckets used for this pivoted conveyor do not overlap adjacent buckets. Therefore, when a conveyed product is dropped on the sending-side path bucket, a part of the conveyed product spills from the gap between the buckets. However, most of the spilled conveyed products are received by the return path bucket from the space between the gap filling members. Then, the conveyed product dropped on the gap filling member is received by the lower return bucket when the movement direction of the gap filling member is changed by the sprocket. Further, the conveyed articles falling on the lower gap filling member are distributed and received by the buckets on both sides of the lower portion at the triangular pointed portions. In this way, since the transported objects other than the bucket do not spill, there is no waste in transporting the transported objects.

Further, a simple structure is possible in which the conveyed product feeder is placed right above the upper stage feeding side bucket and the conveyed product is dropped directly into the bucket. Therefore, for example, neither a device for changing the supply direction of the conveyed object nor an extra space for it is required, and it does not cost much. In addition, since there is a gap between adjacent buckets, for example, attaching special accessories to the chain or moving the return side bucket downwards, the buckets with flanges overlap each other. There is no need to prevent it, and the bucket can be kept facing upward at all times, and the bucket can be moved stably.
