2. Description of the Related Art For example, when conveying powdered or granular food such as sugar, a vibrating conveying device is used from the viewpoint of hygiene. The reason will be explained. A belt forming a normal belt transport device is divided into an upper transport unit on the upper side and a lower transport unit on the lower side. Then, after the object to be conveyed is conveyed by the upper conveying section, the circular traveling is repeated such that the upper conveying section enters the lower conveying section. As a result, when food is conveyed by a normal belt conveyor, it is necessary to cover the entire upper and lower conveyors in order to prevent foreign matter from entering. However, in the case of a vibrating transfer device, the transfer section (trough) travels around.
There is no concept of. As a result, in order to prevent foreign matter from entering, it is only necessary to cover the portion of the trough, which simplifies the structure. Further, in the vibrating transfer device, since the transferred object is vibrated and transferred, the degree of adhesion of the transferred object to the trough can be reduced as compared with a normal belt transfer device, and cleaning is easy. is there.

As shown in FIG. 6, the trough 51 in the conventional vibration transfer device has a substantially rectangular shape. For this reason,
When the powdery granular material S having high hygroscopicity like sugar is vibrated and conveyed, the sugar existing in the trough 51 adheres to the bottom of the trough 51, particularly the corners 52 on both sides thereof. In this case, since the transfer capacity of the vibration transfer device is lowered, it is necessary to perform cleaning regularly. Also,
Even when the type of the transported object S is changed, cleaning is necessary in order to prevent mixing.

For this purpose, it is necessary to remove the cover 53 of the trough 51. Although this work is carried out manually, the cover 53 is a long object and a heavy object, so that the work becomes large. Also, it is necessary to re-assemble after the work is completed. Also, trough 51
Since the inside is washed by spraying water, it takes time to drain and dry it after the work.

As a result, the trough 1 is reciprocally vibrated substantially along the vibration direction P.

A water supply pipe 35 is arranged in the inner space of the trough 1. The water supply pipe 35 is arranged substantially at the center in the width direction of the trough 1 in a cross-sectional view, and at the height position of the connecting portion between the trough 1 and the cover 4 along the longitudinal direction of the trough 1. ing. The water supply pipe 35 supplies a cleaning liquid for cleaning the inner wall surface of the trough 1. The cleaning liquid of this embodiment has a temperature of 5

5 is installed. The operator is
By removing the, the inside of the trough 1 can be inspected through the windows 44. In other words, it is not necessary to disassemble parts of the trough 1 in order to perform an inspection inside the trough 1.

The operation of the vibrating and conveying apparatus A _{1 according to} the present invention will be described when the conveyed object S is sugar.
Here, when the conveyed object S to be vibrated and conveyed is a small part, a method is adopted in which the small part is flipped up and conveyed by vibration. Therefore, the transported object S is transported at the same height position or from a low place to a high place. However, in the case where the transported object S is a fine powdery substance such as sugar, it is difficult to jump up the transported object S because they are housed in close contact with each other. In other words, when the transported object S is a granular material, there is no limitation in the transport direction, and the trough 1 of the vibration transport device A ₁ is tilted forward to transport the transported object S from a high place to a low place. It is desirable to let By doing so, the conveyed object S is conveyed in a state where the action of gravity is added to the action of vibration, so that it is possible to convey a large amount and at high speed.
For the above-mentioned reason, the trough 1 of the vibrating transfer apparatus A ₁ of this embodiment is installed in a state of being inclined forward with respect to the installation surface F at the installation angle α.

As shown in FIG. 1, when the drive motor 22 is operated to rotate the crankshaft 23, the trough 1
Are reciprocally vibrated along the vibration direction P. Therefore, the transported object S (sugar) contained in the trough 1 is vibrated and transported. In FIG. 1, the transport direction of the transported object S is indicated by an arrow Q. Moreover, since the trough 1 of the vibrating and conveying apparatus A ₁ of the present embodiment is installed in a state of being inclined forward with respect to the installation surface F at the mounting angle α, the object S to be conveyed is subjected to the action of gravity. It is transported in the state where it was processed. Therefore, the transportation efficiency is good. Since the outer peripheral portion 2 of the trough 1 has a substantially semi-elliptical cross-sectional shape, the transported object S accommodated in the trough 1 is always brought close to the bottom portion 2a (the lowest portion of the outer peripheral portion 2). It is transported in the state where it was kept. In other words, the transported object S is transported toward the bottom portion 2a in a state of falling, and is less likely to stay on both sides of the outer peripheral portion 2 in the width direction. As a result, even if the transported object S has a hygroscopic property, it is difficult to adhere to the inner wall surface of the trough 1 (in particular, both side portions in the width direction).

Next, the operation of cleaning the inside of the trough 1 will be described. The vibration transfer device A ₁ is stopped, the hot water W is supplied to the water supply pipe 35, and jetted from each nozzle 37. The warm water W ejected in a diffused state from each nozzle 37 is
The transported object S that has adhered to the inner wall surfaces of the trough 1 and the cover 4 is removed. Since no human labor is required for this work, hot water W of high temperature can be used. Further, since it is not necessary to separate the trough 1 and the cover 4 when cleaning the inside of the trough 1,
The cleaning operation is extremely simple. Further, since the trough 1 is attached to the installation surface F in a forwardly inclined state at the attachment angle α, the warm water W after washing flows out as it is, and the receiving portion 41 provided at the front end portion of the trough 1. After being collected by the drain pipe 42, it is discharged through the drain pipe 42. In particular,
When the transported object S is sugar, the sugar peeled off from the inner wall surface of the trough 1 by the warm water W is directly dissolved in the warm water W and discharged. And the recovered warm water W
From, sugar can be refined. In this way, the hot water W after cleaning and the adhered object S to be conveyed need only be discharged once, and the efficiency of the cleaning operation can be improved.

High-pressure steam may be used.

Alternatively, a switching valve (not shown) may be provided at the supply source of the outer water supply pipe 38 (see FIG. 1), and the cleaning liquid and the air may be alternately supplied by the switching valve.
In this case, the water supply pipe 35 in the trough 1 also has a function as an air supply device. Then, after cleaning the inside of the trough 1 with a cleaning liquid such as warm water W, the switching valve can be switched to supply air and eject air into the trough 1. By doing so, the inner wall surfaces of the trough 1 and the cover 4 after cleaning can be quickly dried.

Trough 1 of the vibrating and conveying apparatus A ₁ of this embodiment
Are attached to the installation surface F in a state of being inclined forward at the attachment angle α. However, the trough 1 may be attached in a state of being tilted backward.
