DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. The conveyor belt 1 is used for the product 2 by the constant speed or the intermittent operation.
Is transported. Two pairs of rotating brushes 3 are provided facing each other on both sides of the conveyor belt 1. The direction of rotation of the pair of brushes 31, 32 located on the upstream side in the flow direction of the conveyor belt 1 rotates in the same direction as the conveyor belt 1 on the facing surface, and the pair of brushes 33, 34 located on the downstream side face the facing surface. Is configured to rotate the conveyor belt 1 in the upstream direction.

[0006] The brush 3 is formed by binding straight fiber fibers of nylon or the like of a predetermined length so as to envelop the circumference of the brush bracket 4. The brush bracket 4 is penetratingly supported by the rotating shaft 5 of the motor 7 standing upright, the brush bracket 4 is also standing upright, and the brush 3 is rotated by the rotation of the motor 7 fixed to the base 6. At this time, the height of the brush 3 can be arbitrarily selected. Side walls 8 are provided to surround the outside of the brush 3 at regular intervals. Further, a rod-shaped pin 9 is vertically provided on the base 3, and its position is inside the outer periphery of the brush 3 as shown in FIG. The mounting position of the pin 9 is arbitrary,
The angle at which the powder is scattered, which will be described later, is determined by the mounting position of the pin 9. The pin 9 is provided higher than the height of the brush 6.

A dusting device 10 is provided above the brush 3. A hopper 12 for accommodating the powder 11 is provided in the dusting apparatus 10, and a discharge port 13 is provided on the lower surface of the hopper 12.
There are several locations. A mesh-shaped wire mesh is attached to the discharge port 13. Further, inside the hopper 12, a brush 14 for feeding the powder 11 to the discharge port 13 and sweeping it further downward is attached around the rotary shaft 15. The discharge port 13 is positioned so that the falling powder 16 falls onto the brush 3, but the powder discharge port is added to a place other than above the brush 3 such as above the conveyor belt 1 through which the product passes. May be provided. Reference numeral 17 denotes powder scattered from the brush 3. The transport belt 1, the brush 3, and the dusting device 10 are surrounded by a box body 18, which is a sealed box body except the inlet 19 and the exit 20 of the transport belt 1. A suction fan 23 is provided in a hole 22 provided in the lower wall surface 21 of the conveyor belt 1. The suction fan 23 is for creating a flow of air in the box body and does not require high output. The slope plate 24 is provided behind the slope plate 24. An exhaust duct 25 is provided adjacent to the slope plate 24, and a filter 26 is provided on the exhaust duct 25. A powder receiving box 27 is provided on the bottom of the box 18.

The powder 11 in the hopper 12 is attached as the falling powder 16 onto the brush 3 located on the side of the conveyor belt 1 from the discharge port 13 provided on the lower surface. Two brushes 3 on the upstream side rotate in the downstream direction with respect to the flow direction of the conveyor belt 1, and on the contrary, two brushes on the downstream side rotate in the upstream direction. Further, since each of the brushes 3 is provided with a pin 9 as a locking member, the brush 3 is locked by the pin 9 and bends, and then is disengaged from the pin 9 and adheres to the brush 3 to collect the fallen powder 16. , Will be scattered in the direction of the arrow. Therefore, the scattered powder 17 scattered from the four brushes 3
Is a position where the intermediate positions of the four brushes 3 on the conveyor belt 1 are concentrated.

The product 2 to be conveyed is the scattered powder 17
The four side-scattered powders 17 are sprayed at the position where is concentrated, and are uniformly attached to the surface and conveyed. In the past, when powder was applied to the spherical product 2, it was difficult for the powder to adhere to the vicinity of the lower surface, but the side surface could be uniformly adhered regardless of the spherical shape. Since the powder can be uniformly attached to the surface of the product 2 without touching the brush 3, it is possible to operate for a long time without the brush 3 sticking. It does not damage the product shape. In this way, the excess of the scattered powder 17 in the box 18 falls below the conveyor belt 1 and is collected in the powder receiving box 27.

Further, in order to prevent the dust scattered and scattered in the box body 18 from flowing out from the inlet 19 and the outlet 20, the suction fan 23 operates to make the box body 18 into a negative pressure, and to the outside. Since it is possible to prevent the dust from flowing out, it is possible to reduce the dust that has hitherto hitherto the work site, thus improving the sanitary environment. By the suction fan 23,
The air mixed with the sucked powder hits the slope plate 24 and is collected in the powder receiving box 27 below. Then, the sucked air is discharged from the exhaust duct 25, but dust that cannot be collected by the slope plate 24 is also collected by the filter 26, and clean air is discharged to the outside.

In this embodiment, four brushes 3 are provided, but the number is not limited. For example, by changing the mounting position of the pin 9 that determines the angle at which the scattered powder 17 is scattered, the flying angle of the scattered powder 17 can be changed, and the number of brushes 3 and the mounting position of the arrangement can be changed accordingly. Therefore, even if the brushes do not face each other, the powder adhesion effect does not change. Further, the suction fan does not need to be so powerful because it only needs to create a negative pressure atmosphere in which air flows to the extent that dust does not flow out from the inlet and outlet of the box.

[0012]

As described above, according to the present invention, the rotating belts are installed on both sides of the conveyor belt for conveying products such as steamed buns with a space between them so that the products can pass without contacting each other.
A dusting device for powder is installed above the brush and comes into contact with the brush,
Since the locking member is provided, the powder that adheres to the brush because it rotates while locking with the locking member will be scattered, and the powder will be evenly distributed on the surface without touching products such as Daifuku rice cake. Can be attached to. These brushes can be applied to the product without touching it, so the viscoelasticity of the product can be operated for a long time without affecting the equipment, and it is extremely hygienic and there is no unevenness between products. Good product can be made. Since the mounting positions of the brushes are located on both sides of the upper surface of the conveyor belt and the distance between them is large enough for the product to pass without touching them, the brushes do not touch the product. Then, while the product is being conveyed, it is possible to scatter the powder from both sides of the surface and evenly adhere the powder. Further, when two pairs are provided facing each other on both sides of the conveyor, the powder is sprayed all at once from the four brushes toward the intermediate position of the brushes, so that the adhesion is further enhanced. Since the powder scattered from the brush concentrates on the intermediate position of the brush, the product passing through this position can adhere the powder evenly to the surface thereof. The present invention encloses the scattered powder in a box so as not to flow out to the outside, and further installs a suction fan in the box to make the inside of the box a negative pressure state, so that the dust from the entrance and the exit of the box is kept outside. Since the outflow can be prevented, the hygienic environment at the work site can be improved.
