JP 2004-216267 A

  However, since the brush is interposed between the sieve screen and the support net, the apparatus becomes complicated, for example, the support net must be provided. In addition, this brush does not provide a sufficient effect for preventing clogging of the sieve screen. Furthermore, there is a problem that the frame is severely damaged by the collision of the brush with the frame.

  The present invention has been made in view of the above-described facts, and an object thereof is to provide a powder sorter, a powder sorter, and a moving member that can improve the permeation efficiency of the permeation means.

  The above object is achieved by the present invention described below.

A moving member comprising a plurality of single members formed of an elastic material and having a circular cross section formed in an annular shape, and the plurality of single members are joined to each other .

According to the first aspect of the present invention, since at least one planar moving member that vibrates the transmission means is placed on the transmission means so as to be freely movable, there is no need for a net for supporting the brush as in the prior art. Thus, the configuration can be facilitated. Moreover, clogging of the transmission means can be prevented efficiently, and the sieving efficiency can be improved. Since the moving member is formed in an annular shape by a wire made of an elastic material, the shape of the moving member itself can be easily deformed, and when the moving member is restored from the deformation, the wire easily vibrates, and the transmission means There is an effect that it becomes easy to give vibration to the. In particular, when the cross-sectional shape of the wire is circular, this effect is further promoted. In addition, the effect of suppressing breakage of the transmission means is improved.

According to the second aspect of the present invention, since the acceleration imparting means for applying acceleration to the powder sorter is provided, the powder sorter can be vibrated automatically.

FIG. 1 shows a state in which each of the plurality of powder sorters 2A to 2D... Is separated. On the mesh 20, brushes 1A to 1C as moving members are placed. In addition, in order to show arbitrarily the powder sorter 2A-2D ..., it may be described as the powder sorter 2. The plurality of powder sorters 2 </ b> A to 2 </ b> D are stacked in close contact with each other in the vertical direction, and are held integrally in the storage body 31. The container 31 is rotationally driven by the rotary moving device 32 together with the plurality of powder sorters 2A to 2D.

  As shown in FIG. 2, the powder sorter 2 includes a large frame body 5 that is formed in a hollow quadrangular column shape and that is reinforced by a support column 10 that constitutes the outermost frame. In the large frame 5, an intermediate frame 6 is provided. That is, the middle frame 6 is formed in a hollow quadrangular prism shape in which one side plate is substituted for the side plate of the large frame 5. Further, the hollow square pillar-shaped middle frame 6 has one side plate instead of the side plate of the large frame 5, and the outer side of the three side plates of the middle frame 6 between the large frame 5 and the middle frame 6. It is located so that the hole 3 and the hole 8 are formed between the side plates of the large frame 5. The holes 3 are alternately positioned on the opposite side in the powder sorter adjacent to the top and bottom, and the holes 8 are provided at the same position.

  The middle frame 6 is provided with a housing frame 7 for housing a frame, which will be described later, on which a mesh 20 is stretched. The container 7 is formed in a hollow quadrangular prism shape in which one side plate is substituted for the side plate of the middle frame 6. Below the container 7, a recovery plate 9 is provided as recovery means.

As shown in FIG. 3, the frame 11 on which the mesh 20 is stretched is formed in a hollow quadrangular prism shape. The frame body 11 is spanned with two reinforcing bars in a predetermined direction (vertical direction) and one reinforcing bar in a direction (lateral direction) perpendicular to the predetermined direction.
The size of the frame 11 corresponds to the hollow size of the quadrangular column of the container 7 shown in FIG. That is, the size of the frame 11 is determined so that the end of the frame 11 abuts on each side plate of the container 7 and one side plate of the middle frame 6.

  In FIG. 4, as shown in the powder sorter 2 </ b> A arranged at the uppermost position, the frame 11 on which the mesh 20 is stretched is accommodated in the container 7, that is, the end of the frame 11 is the container 7. When contacting the side plate, the recovery plate 9 is positioned below the mesh 20. As shown in FIGS. 1 and 4, one end of the frame 11 is adjacent to the hole 3. That is, the one end side of the mesh 20 is adjacent to the hole 3. The collection plate 9 is inclined toward the hole 8 and is connected to the hole 8 through a slit-like discharge port 91. In the hole 8, a plurality of wire rods 81 are installed between the large frame body 5 and the middle frame body 61 (lower side).

Although the frame body 11 is not accommodated in FIG. 2, the upper surface of the mesh 20 is connected to the hole 3 when the frame body 11 is accommodated in the accommodation body 7. Moreover, when the powder sorters 2A to 2D... Are stacked one above the other, the upper end surface and the lower end surface of the inner frame 6 are in close contact, and the upper surface of the mesh 20 is connected only to the hole 3 and from the hole 8. Be isolated.
The hole 8 is provided at the same position in each of the powder sorters 2A to 2D..., And in the state where the powder sorters 2A to 2D. A collection box is provided at the lower end of the fall path.

  By the way, the powder sorting apparatus of this Embodiment is mounted in the state which piled up several powder sorter 2A-2D ... on the rotational movement apparatus 32. As shown in FIG. As shown in FIG. 4, in a state where the powder sorters 2 </ b> A to 2 </ b> D are overlapped, the holes 3 of the respective powder sorters 2 </ b> A to 2 </ b> D are alternately opposite in the order in which they are overlapped. So that it is arranged. That is, the powder dropped from the hole 3 falls on the mesh 20 of the next powder sorter.

  And brush 1A-1C as a moving member is mounted on the mesh 20 of each powder sorter 2A-2D .... The brushes 1A to 1C come into contact with the upper surface of the mesh 20 in a freely movable state. At least one brush 1A-1C is mounted. A plurality of brushes may be placed on each mesh 20, brushes having the same configuration may be placed, or brushes having different configurations may be placed. Each of the brushes 1A to 1C has a hole. More specifically, the brushes 1A to 1C are made of a wire made of an elastic material. And the minimum width of brush 1A-1C is longer than the width | variety of the hole 3, More preferably, when the distance from the gravity center position of the brush 1A-1C to the minimum width end is longer than the width | variety of the hole 3. Good. This is because the brushes 1 </ b> A to 1 </ b> C are prevented from falling into the hole 3.

  Next, the operation of the present embodiment will be described. The powder is placed on the mesh 20 of the powder sorter 2A arranged at the uppermost position. The rotation moving device 32 rotates and moves the powder sorters 2A to 2D. This rotation is to move the circular trajectory with the orientation (posture) of the powder sorters 2A to 2D... Fixed around a predetermined rotation center. By applying such rotation to the powder sorters 2A to 2D..., Acceleration (centrifugal force) whose direction always changes is applied to the powder sorters 2A to 2D.

  The powder placed on the mesh 20 of the powder sorter 2A is shaken in the plane direction including the top of the mesh 20 on the mesh 20 by the action of the rotary moving device 32, and the powder is less than a predetermined size. Is partially permeable through the mesh 20. Further, the powder having a predetermined size or larger does not pass through the mesh 20 and is guided (dropped) to the lower powder sorter 2B through the hole 3.

  The powder that has passed through the mesh 20 (powder of less than a predetermined size) is placed (recovered) on the recovery plate 9. Since the collection plate 9 is inclined toward the hole 8 and connected to the hole 8 as described above, the powder having a size less than a predetermined size placed on the collection plate 9 drops through the hole 8. Then, it is collected in a collection box (not shown) provided in the rotary moving device 32.

  Not all powders of a predetermined size or more guided (dropped) through the holes 3 of the uppermost powder sorter 2A are necessarily powders of a predetermined size or more. That is, even if the powder is smaller than a predetermined size, it may not be sieved out in the initial selection, and may be discharged together with the powder having a predetermined size or larger. In particular, the powder located on the upper part of the powder accumulated on the mesh 20 may be discharged into the hole 3 without contacting the mesh 20.

  Thus, the powder of a predetermined size or more guided (dropped) downward through the hole 3 in this way is guided onto the mesh 20 of the powder sorter 2B superimposed under the powder sorter 2A. Is done. The powder falling on the mesh 20 of the powder sorter 2B from the hole 3 of the powder sorter 2A falls to a position farthest from the hole 3 of the powder sorter 2B. And when moving to the hole 3 by the vibration of the powder sorter 2B, it is sieved by the mesh 20.

  Thereafter, the same action as described above is repeated while the powder moves to the lower powder sorter 2 step by step. That is, by repeating the sieving with the mesh 20, powder of a desired size can be sieved with high efficiency. The powder having a predetermined size or more is finally collected in another collection box (not shown) provided in the rotary movement device 32.

  As described above, the brushes 1A to 1C that are freely movable and are in contact with the mesh 20 are placed on the mesh 20 of each of the powder sorters 2A to 2D. That is, the brushes 1A to 1C relatively move freely on the mesh 20 by the movement of the powder sorters 2A to 2D. The brushes 1 </ b> A to 1 </ b> C move on the mesh 20 to locally vibrate on the mesh 20 in a plane direction including the upper surface of the mesh 20, and stir the powder on the mesh 20. Further, when the brushes 1 </ b> A to 1 </ b> C freely move, they repeatedly collide with the inner wall surface of the middle frame 6. Due to this collision, the mesh 20 is vibrated via the middle frame 6. Furthermore, although the brushes 1A to 1C themselves are deformed at the time of a collision, the brushes 1A to 1C are easily restored because they are made of an elastic material. Since the brushes 1 </ b> A to 1 </ b> C also vibrate at the time of restoration, this vibration is transmitted to the mesh 20, and there is an effect of vibrating the mesh 20. Due to the vibration of the mesh 20, clogging of the powder is suppressed.

  Further, since the brushes 1A to 1C are made of an elastic material, they have an impact absorbing action, and the brushes 1A to 1C damage the middle frame body 6 due to collision with the middle frame body 6, or the mesh 20 The inconvenience of breaking is suppressed. Furthermore, since the brushes 1A to 1C have an action of placing the powder on the powder and pressing the powder in the direction of the mesh 20, the brush 1A to 1C also has an action of promoting the powder passing through the mesh 20. Since the powder is agitated by the movement of the brushes 1A to 1C, the powder located at the upper part of the powder reservoir on the mesh 20 also easily comes into contact with the mesh 20, and passes through the mesh 20 without being discharged from the hole 3. It is configured to be easy to do.

  Since powder falls on the brushes 1A to 1C from above, it is considered that the brushes 1A to 1C accumulate on the brushes 1A to 1C. However, in the present embodiment, each of the brushes 1A to 1C is formed with a hole, that is, made of an elastic material, so that the accumulation on the brushes 1A to 1C can be reduced.

  As described above, in the present embodiment, since the brush that vibrates the mesh is placed so as to be freely movable on the mesh, the range in which the brush can move on the mesh is not limited, and clogging is prevented. The range of possible meshes can be expanded, and mesh clogging can be efficiently prevented.

  Further, as shown in FIG. 5, in the present embodiment, the hole BH is formed in the brush, that is, the wire BL is configured, so that the powder can reach the mesh through the hole BH, and the brush It is possible to reduce the fact that it interferes with powder selection.

Furthermore, since the brush is made of an elastic material, the brush can be prevented from breaking the mesh or the frame.
And since the minimum width | variety of the brush is made longer than the hole which guides powder below, it can suppress that a brush enters a hole.

  Since the brush of this embodiment is formed in an annular shape by a wire made of an elastic material, the shape of the brush itself can be easily deformed, and the wire can easily vibrate when restored from the deformation. There is an effect that vibration is easily applied to the mesh. In particular, when the cross-sectional shape of the wire is circular, this effect is further promoted. In addition, the effect of suppressing breakage of the mesh is improved. In addition, the brushes 1A to 1C are configured by joining a plurality of annular single elements formed of the wire rod BL, but are not limited to this shape, and the brush is formed by one annular single element. It may be configured.

Furthermore, in addition to an annular shape, a polygonal ring may be used. Furthermore, it is good also as the shape which woven several wire rod BL in mesh shape. Further, it may be a brush in which one or two or more through holes are formed in the thickness direction with respect to the plate-like elastic material without being constituted by the wire BL. In this case, the entire plate material may not be formed of the elastic material, but only the peripheral end portion of the plate material may be formed of the elastic material.
