  First, before describing the apparatus of the present invention, an impeller capable of aligning the posture of the apparatus of the present invention will be described with reference to the drawings.

As an example, the apparatus of the present invention can align the posture of the impeller 9 as shown in FIG. That is, the posture of the impeller 9 in which the protruding shaft 9b and the plurality of blades 9c are formed on one surface of the disk-shaped hub 9a can be made uniform.
When the surface of the hub 9a having the blades 9c is in an upward posture (hereinafter simply referred to as the blades 9c upward), the impeller 9 is opposite to the blades 9c of the hub 9a as shown in FIG. The surface is in contact with the plane S. When the surface of the hub 9a having the blades 9c is in a downward posture (hereinafter simply referred to as the blades 9c downward), the hub 9a is placed on the surface S as shown in FIG. The posture is inclined with respect to the shaft 9b, or the posture in which the shaft 9b stands with respect to the surface S as shown in FIG.
The apparatus of this invention is an apparatus which reverses the impeller with which the wing | blade became downward about the impeller as shown in FIG. 1, and aligns it upwards. That is, it is an apparatus that reverses the impeller 9 in the posture shown in FIGS. 2B and 2C and aligns it with the posture shown in FIG.

  Next, an embodiment of an impeller attitude alignment device of the present invention will be described with reference to the drawings.

  As shown in FIG. 3, the apparatus of this embodiment includes a conveyor 1 and reversing members 2 and 3. Hereinafter, the components will be described in detail.

(Conveyor)
As shown in FIG. 3, the conveyor 1 has a conveyor surface 1a and a motor 1b that drives the conveyor surface 1a to move in the direction of the thick arrow. The conveyor surface 1a moves with the impeller 9 mounted thereon, and can transfer the impeller 9 from the upstream side on the right side of the figure to the downstream side on the left side of the figure.

  Here, the conveyor surface 1a is preferably a surface on which the impeller 9 is difficult to slip. For example, the conveyor surface 1a is preferably a high friction belt such as the conveyor 1 being a belt conveyor. Thereby, as will be described later, the impeller 9 in contact with the reversing members 2 and 3 can be easily reversed and the posture can be easily aligned.

  Moreover, in the apparatus of this embodiment, although the conveyor surface 1a is leveled, the conveyor surface 1a can also be made into the surface of a climbing gradient. In other words, the conveyor surface 1a can be a surface on which the impeller 9 climbs. As a result, as will be described later, the impeller 9 with the blades 9c facing downward is reversed from the posture in which the direction of the shaft 9b is aligned, and the posture can be easily aligned.

(Reversing member)
As shown in FIG. 3, the reversing members 2 and 3 are plate-like members and are supported by fixing members 4 and 5 disposed above the conveyor surface 1 a, so that the lower end portions 2 a and 3 a are free. Suspended. And the space | interval of lower end part 2a, 3a and the conveyor surface 1a is made into the space | interval which the lower end part 2a, 3a contacts the impeller 9. FIG.

  Here, it is preferable that the reversing members 2 and 3 are flexible members that have a surface on which the impeller 9 is difficult to slide, such as rubber sheets. Thereby, when the impeller 9 contacts the lower end portions 2a and 3a, the lower end portions 2a and 3a are pushed downstream, and the reversing member is deformed like a bow. That is, if it sees as the lower end parts 2a and 3a, it will move to a downstream side by contact. Thereby, the impeller 9 can be transferred while being in contact with the lower end portions 2a and 3a, and the impeller 9 can be easily discharged to the downstream side and smoothly transferred without being retained.

  Further, the deformed reversing members 2 and 3 generate a restoring force that attempts to recover from the deformed state due to their own weight. By this restoring force, the reversing members 2 and 3 can give a tipping moment to the impeller 9, and the impeller 9 with the blades 9c turned downward can be reversed and aligned upward.

In the above description, the reversing members 2 and 3 having flexibility have been described. However, the reversing members 2 and 3 may be members that can be moved by the movable fulcrums of the lower end portions 2a and 3a.
For example, as shown in FIG. 4A, the reversing members 2, 3 are fastened to the fixed members 4, 5 by a hinge 8 so that the reversing members 2, 3 can be swung with the hinge 8 as a movable fulcrum. May be a hard member. Further, as shown in FIG. 4 (b), a hard member may be connected by a movable fulcrum such as a hinge 8 to make the reversing members 2 and 3 swingable.
In any of the reversing members 2 and 3, when the impeller 9 comes into contact with the lower end portions 2a and 3a, the impeller 9 can be transferred while maintaining the contact. Thereby, the impeller 9 can be easily discharged to the downstream side and smoothly transferred without being retained.

  Further, the reversing members 2 and 3 that enable the lower ends 2a and 3a to be moved by the movable fulcrum generate a restoring force for returning to the original position due to their own weight when the lower ends 2a and 3a move. By this force, the reversing members 2 and 3 can give a tipping moment to the impeller 9, and can reverse the impeller 9 with the blades 9 c facing downward and align them upward.

The flexible reversing members 2 and 3 locally deform the lower end portions 2a and 3a that are the contact points with the impeller 9, and can reduce the impact when the impeller 9 comes into contact. Further, the reversing members 2 and 3 that allow the lower end portions 2a and 3a to be moved by the movable fulcrum limit the moving direction and the direction of the restoring force that accompanies them, and efficiently give the impeller 9 the overturning moment necessary for reversal. Can do.
In this way, the reversing members 2 and 3 can give the impeller 9 a falling moment necessary for reversal, with different effects depending on the material. Therefore, the materials for the reversing members 2 and 3 can be appropriately selected according to the material and shape of the impeller 9.

  Moreover, in the apparatus of this embodiment, the reversing members 2 and 3 are made into plate-shaped members that are wider than the impeller 9, and the reversing member surfaces 2b and 3b intersect with the moving direction of the conveyor surface 1a. Is preferred. And it is more preferable to make the angle which cross | intersects substantially perpendicular | vertical like the apparatus of this embodiment. Thereby, when the impeller 9 is transferred while being brought into contact with the lower end portions 2a and 3a, the contact between the impeller 9 and the lower end portions 2a and 3a is easily maintained, and the impeller 9 is easily given a falling moment. It becomes easy to reverse the impeller 9 in which the blades 9c face downward.

Moreover, as shown in FIG. 3, it is preferable to arrange a plurality of reversing members 2 and 3 in the moving direction of the conveyor surface 1a. As a result, as will be described later, the opportunity to give a falling moment to the impeller 9 with the blades 9c turned downward is increased, and the impeller 9 is easily reversed. In this embodiment, the two reversing members 2 and 3 are disposed, but three or more reversing members may be disposed depending on the space of the apparatus. Thereby, it becomes easier to reverse the impeller 9 with the blades 9c facing downward.
Further, the interval between the reversing members 2 and 3 is preferably set such that the impeller 9 comes into contact with the reversing member 3 after the impeller 9 is separated from the reversing member 2. Thereby, it becomes easier to reverse the impeller 9 with the blades 9c facing downward.

Moreover, it is preferable that the reversing members 2 and 3 have a sufficiently long suspension length with respect to the impeller 9. Accordingly, when the impeller 9 is transferred while being brought into contact with the lower end portions 2a and 3a, the deformation and deflection angle of the lower end portions 2a and 3a are reduced, and the direction of the restoring force of the lower end portions 2a and 3a is changed to that of the impeller 9. The direction can be opposite to the transfer direction. And it becomes easy to give a tipping moment to the impeller 9, and it becomes easy to reverse the impeller 9 in which the blade | wing 9c turned downward.
Further, the reversing members 2 and 3 can attenuate the vibration of the lower end portions 2a and 3a more quickly after being separated from the impeller 9 by making the suspension length sufficiently longer than the impeller 9. . Thereby, the attitude | position of the impeller 9 can be continuously arranged with a short space | interval.

  The suspension length (L) of the reversing members 2 and 3 is the difference between the height of the impeller 9 on the conveyor surface 1a and the suspension height of the reversing members 2 and 3, that is, the reversing members 2 and 3 are blades. It is preferable to set based on the contact length (x) that contacts the vehicle 9, and it is preferable to set L to be 10 times or more of x. Thereby, the said effect | action can be acquired more effectively.

Next, an operation in which the apparatus of this embodiment aligns the posture of the impeller 9 will be described.
As shown in FIG. 3, in the apparatus according to the present embodiment, when the impeller 9 is placed on the upstream side of the conveyor surface 1a and the motor 1b is driven, the impeller 9 is transferred by the conveyor surface 1a and the reversing member 2 is moved. To reach. At that time, the impeller 9
1) The blade 9c faces downward, and the shaft 9b faces the transfer direction.
2) The blade 9c faces downward and the shaft 9b faces in a direction other than the transfer direction.
3) The blade 9c faces downward and the shaft 9b stands upright with respect to the conveyor surface 1a.
4) The wing 9c faces upward.
There is a possibility of reaching the reversing member 2 in the four types of postures.
In the following description, the operation in which the apparatus of the present embodiment aligns the posture of the impeller 9 will be described separately for the above cases.

(When the wing 9c is directed downward and the shaft 9b is directed in the transfer direction)
As shown in FIG. 5 (a), when the impeller 9 reaches the reversing member 2 with the blades 9c facing downward and the shaft 9b facing in the transfer direction, the reversing is performed as shown in FIG. 5 (b). The member 2 is deformed like a bow and is transferred while the impeller 9 is in contact with the lower end 2a. And the inversion member 2 generate | occur | produces the restoring force F which tries to recover from a deformation | transformation state with the dead weight.

  Here, considering the balance of moments about the contact point O between the conveyor surface 1a and the hub 9a, the impeller 9 has a moment to rotate the impeller 9 clockwise by the restoring force F, that is, A tipping moment is given. The impeller 9 is given a moment to rotate the impeller 9 counterclockwise, that is, a stable moment, by its own weight mg acting on the center of gravity G of the impeller 9.

  Here, due to the shape shown in FIG. 1, the impeller 9 is in an unstable posture when the blades 9c are directed downward. Therefore, when a tipping moment exceeding the stability moment is applied to the impeller 9 from the lower end portion 2a, the impeller 9 rotates clockwise around the point O, and when the center of gravity G exceeds just above the point O, Flip in the direction of the thin arrow. Then, as shown in FIG. 5 (c), the impeller 9 is discharged from below the reversing member 2 deformed like a bow, with the blades 9c facing upward, and transferred by the conveyor surface 1a without staying there. .

  Then, the impeller 9 reaches the reversing member 3 by the conveyor surface 1a with the blades 9c facing upward, and the blades 9c, which will be described later, reach the reversing member 3 as described below. 9c is transported without staying upward and reaches the downstream end of the conveyor surface 1a.

(When the wing 9c faces downward and the shaft 9b reaches in a direction other than the transfer direction)
As shown in FIG. 6A, when the impeller 9 reaches the reversing member 2 with the blade 9c facing downward and the shaft 9b oriented in a direction other than the transfer direction, as shown in FIG. The reversing member 2 is deformed like a bow, and transports the impeller 9 while making contact with the lower end 2a. And the inversion member 2 generate | occur | produces the restoring force F which tries to recover from a deformation | transformation state with the dead weight.

  Also in this case, the impeller 9 is given a falling moment due to the restoring force F and a stable moment due to its own weight mg in opposite rotational directions. Here, due to the shape shown in FIG. 1, the impeller 9 is in an unstable posture when the blades 9c are directed downward. Therefore, when a tipping moment exceeding the stability moment is applied to the impeller 9 from the lower end portion 2a, the impeller 9 rotates around the contact point O between the conveyor surface 1a and the shaft 9b. At that time, the impeller 9 may rotate until the blades 9c face upward. However, in many cases, the impeller 9 does not rotate due to the positional relationship between the reversing member 2 and the disk-shaped hub 9a. ), The blade 9c is discharged downward and the shaft 9b is directed in the transfer direction from below the reversing member 2 deformed like a bow, and is transferred by the conveyor surface 1a without staying there.

  The impeller 9 reaches the reversing member 3 by the conveyor surface 1a with the blade 9c facing downward and the shaft 9b facing the transfer direction. In the reversing member 3, as shown in FIG. Is turned upside down and reaches the downstream end of the conveyor surface 1a.

(When the wing 9c faces downward and the shaft 9b reaches the conveyor surface 1a upright)
As shown in FIG. 7A, when the blade 9c faces downward and the shaft 9b stands upright with respect to the conveyor surface 1a and the impeller 9 reaches the reversing member 2, the blade 9c reaches the reversing member 2 as shown in FIG. In addition, the reversing member 2 is deformed like a bow, and transports the impeller 9 while making contact with the lower end 2a. And the inversion member 2 generate | occur | produces the restoring force F which tries to recover from a deformation | transformation state with the dead weight.

  Also in this case, the impeller 9 is given a falling moment due to the restoring force F and a stable moment due to its own weight mg in opposite rotational directions. Here, due to the shape shown in FIG. 1, the impeller 9 is in an unstable posture when the blades 9c are directed downward. Therefore, when a tipping moment exceeding the stability moment is applied to the impeller 9 from the lower end portion 2a, the impeller 9 rotates clockwise around the point O. At that time, the impeller 9 may rotate until the blades 9c face upward, but in many cases, the impeller 9 does not rotate so far, as shown in FIG. 7C, the reversing member 2 deformed into a bow shape. From the bottom, the blades 9c are directed downward and the shaft 9b is directed in the transfer direction, and are discharged by the conveyor surface 1a without staying.

  Then, the impeller 9 reaches the reversing member 3 by the conveyor surface 1a with the blades facing downward and the shaft 9b facing the transfer direction. In the reversing member 3, as shown in FIG. It is inverted so as to face upward and reaches the downstream end of the conveyor surface 1a.

(When the wing 9c reaches upward)
As shown in FIG. 8 (a), when the impeller 9 reaches the reversing member 2 with the blades 9c facing upward, the reversing member 2 is deformed into a bow as shown in FIG. The part 2 a is transferred while being in contact with the lower end part 2. And the inversion member 2 generate | occur | produces the restoring force F which tries to recover from a deformation | transformation state with the dead weight.

  Also in this case, the impeller 9 is given a falling moment due to the restoring force F and a stable moment due to its own weight mg in opposite rotational directions. Here, due to the shape shown in FIG. 1, the impeller 9 is in a stable posture when the blades 9c face upward. Therefore, even with the reversing member 2 described above, the stability moment can be made larger than the overturning moment. In this case, as shown in FIG. 8C, the impeller 9 is deformed into a bow shape. From below, the blades 9c are discharged upward and transferred by the conveyor surface 1a without staying.

  Then, the impeller 9 stays with the blade 9c facing in the same manner as when the blade 9c is directed upward, reaches the reversing member 3 by the conveyor surface 1a, and reaches the reversing member 2. Without being transferred, and reaches the downstream end by the conveyor surface 1a.

  As described above, the apparatus according to the present embodiment includes the reversing members 2 and 3 that give a tipping moment to the impeller 9 so that the impeller 9 placed on the conveyor surface 1a is aligned with the blades 9c upward. , And can be transferred to the downstream end of the conveyor surface 1a. And the impeller 9 is smoothly transferred without staying by transferring the lower end parts 2a and 3a of the reversing members 2 and 3 while being in contact with the impeller 9.

  As mentioned above, although the apparatus of this invention has been demonstrated based on embodiment, the apparatus of this invention is not limited to the apparatus of embodiment. In the technical scope described in the claims, the configuration can be freely changed.

  For example, with the apparatus of the present embodiment, the impeller 9 can be climbed up with the conveyor surface 1a as an upward slope. By doing in this way, about the impeller 9 in which the blades 9c are directed downward, the shaft 9b can be aligned in the transfer direction, and the reversing member 2 efficiently reverses the impeller 9 in which the blades 9c are directed downward. Thus, the posture of the impeller 9 can be made uniform.
