Abstract

PROBLEM TO BE SOLVED: To provide a charging device for preventing powdered/granular materials from being damaged when the powdered/granular materials such as feed are to be housed in a storing bag. SOLUTION: A feed charging path 10 is provided with an extensible and retractable cylinder 6 which is provided with a center shaft 4 in its interior. The center shaft 4 is fixed to a lower part of a storage means and contracted in accordance with the upward movement of a storing bag. A plurality of baffles 2, each having a substantially half-round shape and a substantially the same diameter as the inner diameter of the cylinder 6, are spirally mounted to the center shaft 4 at positions around it. The buffles 2 are disposed at predetermined intervals in the axial direction of the center shaft 4 in such a manner than an end of a lower side of the baffle 2 is positioned above an upper portion of another baffle 2 disposed below the former one. Further, each buffle 2 has a smooth surface formed of a resin so as to allow the feed to slidingly drop, and an angle of twist of each buffle 2 assumes an angle at which the charging speed of the feed is sufficiently decelerated so that the feed is not damaged when it is dropped into the storing bag, without reducing the charging speed as much as possible. With this arrangement, when powdered/granular materials, which have slid down on the baffle 2, drop from the end thereof, they drop onto the upper part of the subsequent baffle 2 disposed beneath the former one and successively drop while reducing the dropping speed, whereby the powdered/granular materials can be prevented from being damaged at the time of their dropping.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeding device for packing granular material such as feedstuff into a storage bag or the like. The present invention relates to an apparatus for feeding a granular material which prevents and reduces generation of crushed powder.

[0002]

2. Description of the Related Art Granular semi-living or dried products are increasing in recent years as feeds for dock foods and livestock. Such feed is prepared by mixing and kneading raw materials such as meat and cereal at a predetermined ratio, shaping into a predetermined shape, drying to a predetermined water content, and adding additives and the like to the surface as necessary. Manufactured. And the manufactured feed is
It is conveyed to the bagging step by the conveyance path, stored in a predetermined container such as a storage bag, packaged, and conveyed.

[0003] When a large amount of feed is required, such as for livestock farmers, or when refilling is carried out to refill smaller bags for individuals, 500 kg per bag is required in a feed manufacturing plant. About 1 ton of feed was packed, and the bag was placed on a truck or the like and transported to a predetermined place to improve the efficiency of product transportation. When a large amount of feed is stored using the storage bag, the height and width are 1
m may be used.

[0004]

However, when storing the feed in the storage bag, the feed is usually once lifted upward by a transport device or the like and then dropped into the storage bag. Therefore, since the storage bag for storing a large amount has a high entrance height, when the powder is dropped from the storage device into the bag in the storage step, the drop speed is high, and the powder at the time of the drop causes the powder to drop. May be crushed.

[0005] Even if a part of the feed becomes powdery due to crushing due to impact or vibration, if it occurs before being stored in the storage bag, such powder can be removed by a sieve or the like. However, the powder that has entered the storage bag cannot be easily removed, resulting in a reduction in commercial value.

Further, in order to reduce the falling speed of the granular material when it is put into the storage bag, a falling passage is formed in a zigzag manner, and a baffle plate is obliquely arranged in the middle of the falling passage to obstruct the granular material. An example is known in which dropping is performed while successively hitting the plate.However, if the inclination angle of the baffle plate is reduced and the slope is lengthened to reduce the falling speed, a drop passage with a large cross-sectional area is required, while the fall passage is narrowed. As a result, an inclined surface having a sufficient length cannot be formed, or the inclination of the baffle plate becomes steep, so that the falling speed cannot be sufficiently reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a charging device in which the crushing of the granular material is small and the falling path is reduced in size during the bagging operation for storing the granular material in a large storage bag.

[0008]

According to the present invention, in order to solve the above-mentioned problems, the charging device is constituted as follows. That is, a plurality of baffle plates of a predetermined length spirally formed in a passage portion where powder or granular material such as feed falls are spaced at a predetermined interval, respectively, and below the falling end of the baffle plate, The baffles arranged on the lower side were sequentially arranged such that the upper ends thereof overlapped.

As a result, when the granular material such as feed falls through the charging device, the granular material is placed on the baffle plate provided in the charging device, and slides down spirally on the baffle plate. Fall into the air at the edge of the board. Then, the dropped particles fall onto the next baffle plate arranged below the baffle plate and spirally slide down on the baffle plate in the same manner as described above.

[0010] Since the powdery material such as the feed falls in this way while sliding on the baffle plate, the falling speed at the time of falling through the charging device is reduced, and the vertical drop distance of the powdery material is reduced. Is not more than the installation interval of the baffle plate,
It is possible to reduce crushing of the granular material when storing the granular material in the bag from the storage device. In addition, since the baffle plate is formed spirally in the charging device, the passage area of the charging device can be reduced, and the entire device can be reduced in size.

The installation interval between the baffle plates is suitably a length corresponding to one pitch of the spiral baffle plate, but is not limited to this, and may be about 0.5 to 2 times the pitch. . The pitch of the baffle is 0.5 to 2 times the diameter of the baffle.
It may be about twice. The baffle plate is preferably made of resin, but may be steel, stainless steel, or the like.

Further, the baffle plate may be continuous, a notch may be provided in a part of the continuous baffle plate, and the powder may fall from the notch. The notch may be formed so that a plurality of baffles are cut out in the falling direction and the plurality of baffles fall continuously.

Also, a plurality of baffle plates may be provided in parallel, and the helix of the baffle plate may be a plurality of spirals. If the baffle is made up of multiple strips,
The granules can be dispersed on each baffle plate, the amount of the granules sliding down on the baffle plate can be reduced and the granules can be dropped smoothly, and the mounting strength of the baffle plate can be reduced.

Further, the periphery of the baffle plate may be covered by a telescopic tubular portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a charging device according to the present invention will be described.

FIG. 3 shows a step of packing the feed. In the bag filling process, the conveyor 30 is passed upward, and the conveyor 30
The storage device 32 is provided below the left end of the storage device.
A lifting device 34 for installing a storage bag 36 is arranged below the storage bag 36.

The charging passage 10 is connected to the lower end of the storage device 32 via an opening / closing device 33. Storage device 32
Is open at the top, and when the feed conveyed by the conveyor 30 is introduced from above and stored in a certain amount inside, a sensor detects the feed and stops carrying in from the conveyor 30. .

As shown in FIG. 2, the lifting device 34 has a mounting portion 38 for mounting the storage bag 36, and a hydraulic device (not shown) for raising and lowering the mounting portion 38. When attached to the section 38, the upper end of the storage bag 36 is gradually raised in accordance with the feed amount.

The storage bag 36 is a cloth bag having a diameter of 1 to 2 m and a rubber or synthetic resin material applied to the surface thereof.
Also, apertures may be provided on the upper and lower sides, respectively.

FIG. 1 shows a charging passage 10.

As shown in FIG. 1, the charging passage 10 has a tubular portion 6 which can be extended and contracted, and a central shaft 4 inside the tubular portion 6. The central shaft 4 is fixed to a lower part of the storage device 32, and the cylindrical portion 6 covers the periphery of the central shaft 4 and contracts as the storage bag 36 rises. As shown in FIG. 1, a plurality of baffle plates 2 are spirally attached to the center shaft 4 around the shaft.
The baffle plate 2 is substantially semicircular and has a diameter substantially the same as the inner diameter of the cylindrical portion 6 so that an excessive gap is not formed between the baffle plate 2 and the inner surface of the cylindrical portion 6.

The baffle plate 2 is fixed at a predetermined interval in the axial direction of the central shaft 4, and the lower end of the baffle plate 2 is placed on an upper portion of the baffle plate 2 disposed thereunder. It is arranged as follows. That is, when the granular material sliding down on the baffle plate 2 falls from the end of the baffle plate 2, it always falls on the upper portion of the next baffle plate 2 disposed immediately below it.

Further, the baffle plate 2 is formed of a resin having a smooth surface so that the feed slides down, and the twist angle is:
Feeding speed is not reduced as much as possible, and
The angle is such that when it falls into 6, it is sufficiently decelerated so as not to be crushed. Specifically, it is appropriately set in consideration of the coefficient of friction between the feed and the baffle plate 2, the falling distance, the strength of the feed, and the like.

Next, the operation of the charging passage 10 will be described.

The feed which has been conveyed from the manufacturing apparatus (not shown) through the conveyor 30 is sequentially carried into the storage device 32 and stored therein. Further, a storage bag 36 is disposed below the storage device 32, and the input port of the storage bag 36 is
Attached to. The storage bag 36 is folded, and the input port is still located below. Further, the cylindrical portion 6 of the charging passage 10 is lowered and connected to the opening of the storage bag 36.

Then, the opening / closing device 33 of the storage device 32 is opened, and the feed is dropped. Then, the feed is supplied to the input passage 10
Draw down a spiral with the baffle plate 2 installed inside and slide down,
When it comes to the end of the baffle 2, it falls from the end and rests on the next baffle 2 attached below the baffle 2.
Then, it falls while drawing a spiral again by the baffle plate 2.

Therefore, the feed speed of the feed is suppressed by the baffle plate 2 so that the feed speed does not become excessively high, and the feed may be clogged during the fall due to the provision of the baffle plate 2 at intervals. Therefore, the powder is stored in the storage bag 36 smoothly without causing crushing, and crushed powder can be prevented from being generated as much as possible.

Next, another example of the baffle will be described with reference to FIG.

In the above example, the baffle plate 2 is attached to the center shaft 4 at a predetermined interval. However, as shown in FIG. 4, the baffle plate 2 is formed continuously in a spiral shape, and a part thereof is notched. 12 may be provided. If the notch 12 is formed in the baffle plate 2 in this manner, the feed can be spirally rotated and dropped, and at the same time, can be dropped vertically from the notch 12 appropriately, and the same effect as described above can be obtained. . The notch 12 is formed not by cutting out one baffle plate 2 but by cutting out the same portion in the vertical direction over a plurality of baffle plates 2 when the pitch is small, for example, so that feed or the like can be cut out by a plurality of baffle plates. 2 and may fall.

FIG. 5 shows another example of the baffle plate. For this, two baffle plates 2 were attached to the central axis 4 in parallel. That is, the baffle plate 2 is made up of a large number of strips. In this way, two fall passages are formed corresponding to the number of the baffle plates 2. When the feed is dropped, the feed is divided into the respective passages. The mounting strength of the plate 2 can be reduced.

[0031]

According to the charging device of the present invention, the spirally formed baffle plate is partially disposed, and the powder is dropped vertically and spirally. Even when a large amount of powder is dropped, it can be dropped smoothly, the drop speed can be sufficiently suppressed, and the vertical drop distance can be shortened. In addition, generation and mixing of crushed powder can be reduced.

Further, since the falling speed of the granular material is reduced by spiral movement, the cross-sectional area of the charging device can be reduced, and effective speed adjustment can be realized.
