Description

[Detailed Description of the Invention] Technical Field The present invention relates to a dispersion device for dispersing a large number of substances introduced at once into a substantially uniform state.

BACKGROUND OF THE INVENTION Such dispersion devices are required in various technical fields. For example, in black-dying treatment where the surface of steel parts such as belts and nuts are coated with black iron oxide, treatment in which the treated object is immersed in a treatment solution containing metallic zinc and chromic acid, and surface treatment for painting, etc. After that, it is dried, and at this time, it is necessary to disperse the material to be treated as uniformly as possible to avoid uneven coating or drying.

For this reason, conventionally, a dispersing device is used which is equipped with dispersing claws that are moved forward, backward, and up and down by a drive device, and the dispersing claws collect the workpieces conveyed from the previous process by a net conveyor. They were being raked and dispersed.

Problems that the invention aims to solve: However, in such a dispersion device, it is difficult to perform good dispersion, so overlapping and unevenness of the objects to be treated cannot be completely eliminated, resulting in uneven coating and uneven drying. In addition, the objects to be processed sometimes got caught in the mesh of the net conveyor, and when this conveyor conveyed different types of objects, they were mixed together. Furthermore, since the material to be processed is forcibly agitated, the dispersion claws are likely to bend or the net conveyor may be damaged, making maintenance difficult and lacking in durability. It was hard to say.

Means for Solving the Problems In order to solve the above-mentioned problems, the dispersion device according to the present invention has a frame-shaped dispersion box body with an open top and bottom, which has parallel and almost horizontal axes at the bottom. A large number of rotatable plates are disposed around the dispersion box so that when they are in a horizontal position, they form a flat bottom plate and form a dispersion box together with the dispersion box main body. A large number of objects put into the dispersion box are dispersed by applying a swinging motion to the dispersion box using a swinging device, and a rotating plate is rotated around the axis using an opening/closing device to disperse the objects. The bottom of the box is opened so that a large number of objects can be discharged downward while maintaining substantially the above-mentioned dispersed state.

Function and Effect In the dispersion device configured as above,
Since many objects are dispersed by the rocking motion given to the dispersion box by the rocking device, they may not be dispersed as well as they would be if they were dispersed by the dispersion claws, or the dispersion claws may be bent. Since the particles do not clump together and are discharged while maintaining their dispersed state after being dispersed, a large number of particles can be evenly dried or subjected to other treatments in the next step. Furthermore, since the rotating plate forming the bottom of the dispersion box forms a flat bottom plate except when discharging a large number of objects, when a large number of objects are dispersed within the dispersion box, they may get caught on the rotating plate. Without a doubt,
Furthermore, since many objects move on a flat rotating plate during ejection, they are definitely ejected, and many objects remain in the dispersion box and get mixed in with the many different types of objects that are thrown in next. Not at all.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail based on the drawings.

In FIG. 1, reference numeral 10 denotes a frame-shaped dispersion box main body with an open top and bottom, and a large number of shafts 12 are arranged on the underside of this main body 10 in parallel with each other and at equal intervals. These shafts 12 are rotatably supported by the main body 10, and a rotary plate 14 is fixed to the upper side of each shaft 12 at the center in the width direction. When in a horizontal position, they are connected to each other to form a flat bottom plate, and together with the distribution box main body 10 constitute a distribution box 16.

A bracket 17 is fixed to the outer surface of the side wall located at one longitudinal end of the dispersion box main body 10, and one end of a connecting rod 18 is rotatably connected to this bracket 17. The portion is connected to a crank pin 21 provided on the disc 20 at a position offset from the center thereof. Disk 20
is fixed concentrically to one end of a shaft 24 rotatably supported by a pair of brackets 22,
A small diameter sprocket 26 is attached to the other end of the shaft 24. The sprocket 26 is connected by a chain 34 to a large diameter sprocket 32 fixed to the output shaft 30 of the motor 28.
The disk 20 is rotated by a motor 28. When the disk 20 is rotated, the distribution box 16 is caused to swing horizontally in its longitudinal direction via the connecting rod 18 which is connected eccentrically to its center.
That is, in this embodiment, the connecting rod 1
8, a disc 20, a crank pin 21, a sprocket 26, a motor 28, a sprocket 32, a chain 34, etc. constitute a rocking device that gives rocking motion to the dispersion box 16.

In addition, the distribution box 16 is provided with 4
wheels 38 are attached and placed on the rails 40, which reduces the power required when the dispersion box 16 is rocked as described above, and also reduces the lateral position of the dispersion box 16. It is designed to prevent misalignment.

A large number of shafts 1 to which the rotating plates 14 are attached
One ends of the arms 42 are respectively projected to the outside of the distribution box main body 10, and one ends of the arms 42 are each fixed to these projections. The other end of each arm 42 is a single bar 4 arranged approximately horizontally.
4, and an L-shaped connecting member 46 is fixed to the upper surface of the bar 44 in a direction extending toward the opposite side from the distribution box 16. The vertically rising portion of the connecting member 46 includes a dispersion box main body 10.
A piston rod 52 of a cylinder 50 is connected to the outer surface of the cylinder 50 by a bracket 48 so as to be rotatable on a vertical plane.
The expansion and contraction of the bar 44 causes the bar 44 to reciprocate in its longitudinal direction, thereby causing the arm 42 to rotate and the rotating plate 14 to rotate around the axis of the shaft 12. As shown in FIG. 2, a stopper 54 is attached to the lower side of each rotary plate 14, and restricts the rotation of the rotary plate 14 in the counterclockwise direction in the same figure. It is made to support. Stoppa 54
are provided so as to come into contact with the rotating plates 14 when the rotating plates 14 are connected to each other to form the bottom of the dispersion box 16, and in this embodiment, each rotation when the piston rod 52 is contracted. While the moving plate 14 contacts the stopper 54 to constitute the bottom plate of the dispersing box 16, the rotating plate 4 is rotated clockwise in FIG. is becoming more open to the public. In this way, in this embodiment, the arm 42, the bar 44, the cylinder 50
An opening/closing device that rotates the rotating plate 14 to open the bottom of the dispersion box 16 is constructed.

In the dispersion device configured as above,
After a large number of coated bolts 56 are transported by appropriate means and placed into the dispersion box 16, the dispersion box 16 is swung by a swinging device to disperse the bolts 56. When the rotating plate 14 is rotated to a nearly vertical position by the opening/closing device, the bolts 56 will fall and the dispersion box 1 will fall as shown in FIG.
The liquid is discharged into a pallet 58 disposed below the pallet 6, and is received by a stainless steel mesh 60 attached around the inside of the pallet 58. At this time, a large number of rotating plates 14 are disposed, and the large number of objects move on the rotating plates on which they are placed, and are moved to the pallet 5.
Therefore, even if the rotating plate 14 is rotated and the bolts 56 are dropped into the pallet 58, the dispersed bolts 56 will not be gathered together, and the dispersed state will be maintained in this way and the bolts 56 will be dropped into the pallet 58. The bolts 56 discharged inside are conveyed to a drying process by a chain conveyor (not shown) or the like.

In this manner, according to the dispersion device of this embodiment, the bolts 56 are reliably dispersed by the swinging motion given to the dispersion box 16, and this state is maintained to ensure that the bolts 56 are dispersed.
Since the bolts 56 are discharged and transported to the drying process, there is no possibility that the bolts 56 overlap and cause uneven coating or drying. In addition, since each rotating plate 14 is connected in a plane when forming the bottom part of the distribution box 16, when the distribution box 16 is swung, the bolts 56
The bolts 56 do not get caught between the rotating plates 14, and even when being discharged onto the pallet 58, the bolts 56
Because they move on a flat rotating plate, they do not remain in the dispersion box 16, and even if a large number of different types of bolts, nuts, etc. are dispersed later, there is no risk that the bolts 56 will be mixed in with them.

In the above embodiment, the rotating plate 14 was fixed to the shaft 12 at the center in the width direction, but the rotating plate 14 was fixed to the shaft 12 at either end in the width direction. Good too.

Further, although the rocking device of the above embodiment was supposed to give only a rocking motion in the horizontal direction to the dispersion box 16, it gives a rocking motion in the vertical direction along with or in place of the rocking motion in the horizontal direction. In other words, it is sufficient to provide a swinging motion that can effectively disperse a large number of objects thrown into the dispersion box 16.

Further, the opening/closing device for opening and closing the bottom of the dispersion box 16 is not limited to the arm 42, bar 44, etc. as in the above embodiment, but may also be constructed using a chain or the like.

Although not illustrated in detail, the present invention can be implemented in various modifications and improvements based on the knowledge of those skilled in the art.
