Abstract

PURPOSE:To prevent a mountainous pile of articles from occurring by connecting a buffer plate, being rockable in using the dropping direction of articles from a transferor as a fulcrum, to a guide rod being liftable in setting this fulcrum to the lower end, and installing a resilient device restricting any rocking angle of this buffer plate. CONSTITUTION:An article 9 slides into a chute 7 to be inclined from a belt conveyor 1. This chute 7 is changed of its angle by a cylinder 12 attached to the lower part, and it lessens any impact in time of transferring to a buffer plate 2 according to the size and weight of the article 9. In this connection, this buffer plate 2 is connected to an interval between two guide rods 5 and 5 via a fulcrum 3, and a coil spring 6 is connected to an end of the buffer plate 2 ant the guide rod 5. When the article 9 drops on the buffer plate 2, this plate 2 is rocked. At this time, since a dropping position of the article 9 is varied in border to the fulcrum 3 of the buffer plate 2, it is dispersedly housed in a bucket 13 between the buffer plate 2 and the belt conveyor 1, or another bucket 13 more frontage than the buffer plate 2, therefore such a possibility that the articles might be mountainously stacked in one spot in the buscket 13 becomes lessened in this way.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock absorber for use in transferring an article transferred by an article transfer apparatus such as a belt conveyor or an apron conveyor to a storage container such as a bucket.

[0002]

2. Description of the Related Art Conventionally, in order to transfer an article transferred by a transfer device to a bucket, the article is simply dropped into a bucket placed below the front end of a belt conveyor. In this case, if the bucket does not contain a considerable amount of goods, the efficiency of transportation is poor, so it is common to enlarge the bucket, and therefore the height at which the goods fall from the belt conveyor also increases, resulting in a large drop impact. There is a problem that the articles collide with each other to cause scratches such as dents, generate a large amount of noise, and damage the bucket. For this reason, a chute is provided below the front end of the belt conveyor to reduce the drop height to mitigate the impact of the fall, thereby coping with the above problem. However, since the bucket interferes with the chute when the bucket for accommodating articles is taken in and out of the conveyor, the chute cannot be lowered below the height of the bucket.

[0003] In order to solve this problem
In Japanese Patent Publication No. 8, a swing plate that swings around a position near the transfer device is provided in front of the transfer device, and
An article transfer shock absorber that non-fixedly connects the rod side chamber with a hydraulic cylinder that communicates via a check valve, and connects the rod of this hydraulic cylinder and the front end side of the fulcrum of the oscillating plate, When riding on the rocking plate, the front end of the rocking plate gently rocks and tilts downward, and the article slides on it and drops into the bucket from a low position, causing the article to be violently put on another article or bucket. Without damaging the article,
There are disclosures that reduce problems such as noise.

[0004]

[Problems to be Solved by the Invention]
The device of Japanese Patent No. 4228 has a cushioning effect, but since the position where the articles fall is determined, the articles are piled up in a part of the bucket, and it is necessary to level the articles in the bucket. The present invention, when transferring articles, prevents the articles from being piled up in a bucket, and also mitigates impact to prevent the articles from being scratched such as dents, and causes problems such as noise. Also aims to reduce.

SUMMARY OF THE INVENTION To achieve the above object, a shock absorbing device for transferring goods according to the present invention is a shock absorbing device for transferring goods which is arranged in front of a transferring device for goods and above a container for storing goods. A device, which is capable of swinging about the falling direction of an article from the transfer device as a fulcrum, a guide rod that can be moved up and down with the fulcrum as a lower end, and the buffer plate and the guide rod are connected to each other. It is characterized by comprising an ammunition for limiting the swinging angle of the buffer plate. Then, a chute that is inclined toward the upper surface of the buffer plate from a position close to the front end of the upper surface of the transfer device is provided.

[0006]

When the article falls from the front end of the transfer device to the buffer plate, the buffer plate swings. At this time, with the fulcrum of the buffer plate as a boundary, depending on the fall position of the article, it falls between the buffer plate and the transfer device or before the buffer plate and is scattered and stored in the storage container. The buffer plate that can be raised and lowered changes the height of the buffer plate according to the volume of articles in the storage container, and changes the drop position of the articles. After the article hits the buffer plate and drops by an ammunition that connects the buffer plate and the guide rod and limits the swing angle of the buffer plate, the article is returned to the original substantially horizontal state. Furthermore, the chute reduces the impact of articles when transferring from the transfer device to the buffer plate.

[0007]

The present invention will be described in detail below. FIG. 1 shows that the transfer device according to one embodiment of the present invention has a drop of 1100 between the container and the container.
It is a perspective view of the shock-absorbing device for article transfer used where mm. In FIG. 1, in front of the belt conveyor 1 (on the left side in the drawing), two guide rods 5 are hung up and down via a rod 10 by a lifting cylinder 4 attached to a machine frame (not shown). I have set up. A fulcrum 3 is provided at the lower end of the guide rod 5. The fulcrum 3 is substantially in the falling direction of the article 9 from the belt conveyor 1. Two
A buffer plate 2 is connected between the guide rods 5 of the book via a fulcrum 3, and a coil spring 6 is connected to the end portion of the buffer plate 2 and the guide rod 5.

Further, there is provided a chute 7 which is inclined from the front end of the upper surface of the belt conveyor 1 toward the upper surface of the buffer plate 2. The article 9 slides from the belt conveyor 1 onto the chute 7. The angle of the chute 7 is changed by the cylinder 12 attached below the chute 7 to reduce the impact at the time of connecting to the cushion plate 2 according to the size and weight of the article 9. When the article 9 falls on the buffer plate 2, the buffer plate 2 swings. At this time, since the falling position of the article 9 is different with the fulcrum 3 of the buffer plate 2 as a boundary, the bucket 9 in the bucket 13 between the buffer plate 2 and the belt conveyor 1 or in front of the buffer plate 2 (left in the figure). Stored scattered in 13 and 1 in bucket 13
It rarely piles up in places.

The buffer plate 2 is moved to the lower position by the elevating cylinder 4 when the volume of articles 9 in the bucket 13 is small, and is increased as the volume of articles 9 increases, whereby the belt conveyor 1 or The drop between the chute 7 and the bucket 13 is divided into two, and the impact at the time of falling is reduced.

As described above, the articles 9 rarely pile up in the bucket 13, and the articles 9 are piled in the bucket 1.
It violently collides with another article 9 previously dropped and stored in 3 or the bucket 13, and prevents scratches such as dents from being made on each other. Furthermore, it is possible to reduce noise generation and bucket damage. After the article 9 hits the buffer plate 2 and drops, the buffer plate 2 returns to the original substantially horizontal state by the coil spring 6 and waits for the transfer of the next article 9.

After the articles 9 are stored in the bucket 13 by a predetermined amount, the elevating cylinder 4 can raise the interference plate 2 to easily replace the bucket 13.

[0012]

As described above in detail, the cushioning device for article transfer according to the present invention is capable of swinging about the falling direction of articles from the transfer device as a fulcrum, and ascending and descending with the fulcrum as the lower end. Since it is composed of a guide rod and an ammunition that connects the buffer plate and the guide rod, articles are stored in a container such as a bucket without being piled up in one place.
Then, the height of the buffer plate is changed according to the volume of the articles in the bucket, to reduce the collision of the articles with other articles previously dropped and stored in the bucket or to collide with the bucket violently. Prevent from getting stuck. Furthermore, the generation of noise can be reduced.
