DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of an impeller attitude alignment device of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following embodiments.
In the following embodiments, an apparatus having a preferable configuration such as a horizontal conveyor surface in addition to a plurality of conveyor surfaces and a plurality of guide surfaces is described. However, the apparatus of the present invention includes a conveyor having a conveyor surface on which an impeller is placed and moved, and a guide that is inclined and extended downstream from one end side to the other end side in the width direction of the conveyor surface. What is necessary is just to comprise the guide member which has a surface. That is, the apparatus of the present invention is basically composed of a single conveyor surface that conveys the impeller and a single guide surface that the impeller contacts.

[First Embodiment]
As shown in FIG. 3, the apparatus of the present embodiment includes a conveyor 1 and guide members 2, 3, and 4, and the conveyor 1 has conveyor surfaces 1 a and 1 b, and guides The members 2, 3, and 4 have guide surfaces 2a, 3a, and 4a, respectively.
Furthermore, the apparatus of this embodiment is equipped with the horizontal conveyors 5 and 6, the sensor unit 7, and the control part 8, and the horizontal conveyors 5 and 6 have the horizontal conveyor surfaces 5a and 6a, respectively. .
Hereafter, the component of the apparatus of this embodiment is demonstrated in detail.

(Conveyor)
As shown in FIG. 3, the conveyor 1 has a conveyor surface 1a and a conveyor surface 1b connected in series, and the conveyor surface 1a and the conveyor surface 1b are driven by a motor 1c and a motor 1d in the direction of the thick arrow in the figure. Like to move on. Thus, the conveyor surface 1a is the upstream conveyor surface, and the conveyor surface 1b is the downstream conveyor surface.
The impeller 9 placed on the upstream side of the conveyor surface 1a is moved to the downstream side of the conveyor surface 1a by the movement of the conveyor surface 1a and the conveyor surface 1b, and then transferred from the conveyor surface 1a to the conveyor surface 1b. Subsequently, the conveyor surface 1b is moved from the upstream side to the downstream side. A motor 1c that drives the conveyor surface 1a is connected to the control unit 8.

  Moreover, the guide members 2 and 3 and the guide member 4 are arranged on the conveyor surface 1a and the conveyor surface 1b, respectively. And in the position where the front-end | tips 2aa and 3aa of the guide surfaces 2a and 3a of the side edge 1aa of the conveyor surface 1a oppose, the horizontal conveyors 5 and 6 which have the horizontal conveyor surfaces 5a and 6a are arranged, and the conveyor surface 1a The sensor unit 7 is disposed on both sides of the connecting portion of the conveyor surface 1b.

The positional relationship between the conveyor surfaces 1a and 1b may be such that the impeller 9 can be transferred from the downstream side of the conveyor surface 1a to the upstream side of the conveyor surface 1b. That is, the moving direction of the conveyor surface 1a and the moving method of the conveyor surface 1b do not need to be parallel, and for example, the moving direction of the conveyor surface 1a and the moving direction of the conveyor surface 1b may be angled.
Moreover, the conveyor surfaces 1a and 1b do not necessarily need to be horizontal, and may have an upward slope in the moving direction of the conveyor surfaces 1a and 1b. The conveyor surfaces 1a and 1b are preferably surfaces on which the impeller 9 is difficult to slip. For example, the conveyor 1 is preferably a belt conveyor and the conveyor surfaces 1a and 1b are preferably rubber surfaces. By doing so, as will be described later, the posture of the impeller 9 in contact with the guide members 2, 3, 4 is likely to occur, and the impeller 9 can be easily reversed.

(Guide member)
As shown in FIG. 3, the guide members 2, 3, 4 are flat members having guide surfaces 2a, 3a, 4a, and the guide surfaces 2a, 3a are raised with respect to the conveyor surface 1a. The guide surface 4a is set up with respect to the conveyor surface 1b. And the guide members 2, 3, and 4 are supported by the fixing | fixed part 2b, 3b, 4b adjacent to the side ends 1aa and 1ba of the conveyor surfaces 1a and 1b.
The guide members 2, 3 and 4 have guide surfaces 2a, 3a and 4a substantially perpendicular to the conveyor surfaces 1a and 1b, and the guide surfaces 2a, 3a and 4a are the widths of the conveyor surfaces 1a and 1b. Extending from the direction to the moving direction, slopes that are alternately inclined at angles α, β, and γ are formed. And guide surface 2a, 3a, 4a forms a space | interval between front-end | tip 2aa, 3aa, 4aa and side edge 1aa, 1ba of conveyor surface 1a, 1b, and the impeller 9 moves the space | interval. I am doing so. Further, the guide members 2, 3, 4 have their surfaces facing the conveyor surfaces 1 a, 1 b approaching or sliding on the conveyor surfaces 1 a, 1 b, and the impeller 9 gets over the guide members 2, 3, 4. The height of the guide surfaces 2a, 3a, 4a with reference to the conveyor surfaces 1a, 1b is set sufficiently higher than the height of the impeller 9 with the blades 9c facing downward.

As will be described later, the impeller 9 with the blades 9c facing down moves and contacts the guide members 2, 3, and 4 together with the conveyors 1a and 1b. Thereafter, the impeller 9 is reversed while moving along the guide surfaces 2a, 3a, and 4a.
Here, the impeller 9 tends to stagnate on the guide surfaces 2a, 3a, and 4a when the inclination angles α, β, and γ of the guide surfaces 2a, 3a, and 4a are reduced, and contacts with the guide surfaces 2a, 3a, and 4a when it is increased. Even if it becomes difficult to reverse.
Therefore, the inclination angles α, β, and γ are preferably set to 30 degrees or more and 60 degrees or less so that the impeller 9 can be reversed without stagnation with the guide surfaces 2a, 3a, and 4a.

The guide surfaces 2a, 3a, and 4a are preferably set substantially perpendicular to the conveyor surfaces 1a and 1b, and more preferably lie at an angle of 5 degrees or less from the vertical to the traveling direction of the conveyor surfaces 1a and 1b. .
In this way, as will be described in detail later, the impeller 9 that has contacted the guide surfaces 2a, 3a, and 4a is likely to slide up on the guide surfaces 2a, 3a, and 4a and take a posture, and is reversed. It becomes easy to do.

  The guide surfaces 2a, 3a, and 4a are preferably surfaces on which the impeller 9 is easy to slip. By doing in this way, the attitude | position of the impeller 9 which contacted the guide surfaces 2a, 3a, 4a becomes easy to occur, and the impeller 9 becomes easy to reverse. The inversion of the impeller 9 will be described later in detail.

Further, the positions of the tips 2aa, 3aa, 4aa of the guide surfaces 2a, 3a, 4a are on the conveyor surfaces 1a, b separated from the side ends 1aa, 1ba. And by driving the conveyor 1, the impeller 9 passes through the tips 2aa, 3aa, 4aa and is discharged from the downstream side of the conveyor surface 1b.
However, depending on the ease of alignment of the impeller 9, the positions of the tips 2aa, 3aa, 4aa are extended to the outside of the conveyor surfaces 1a, 1b, and the impeller 9 is not discharged from the downstream side of the conveyor surface b. You may make it discharge | emit from the side of surface 1a, 1b. In addition, when discharging the impeller 9 from the front ends 2aa and 3aa of the guide surfaces 2a and 3a, the horizontal conveyors 5 and 6 do not disturb the discharge.

(Horizontal conveyor)
The apparatus of the present invention preferably includes a horizontal conveyor as shown in FIG. Hereinafter, the example of a horizontal conveyor is demonstrated.
As shown in FIG. 3, the horizontal conveyors 5 and 6 have horizontal conveyor surfaces 5a and 6a. The horizontal conveyor surfaces 5a and 6a stand up with respect to the conveyor surface 1a, and the guide surfaces 2a and 3a It is arranged on the extension direction side. And by driving the motors 5b and 6b, the horizontal conveyor surfaces 5a and 6a are moved in the direction opposite to the conveyor surface 1a (in the direction of the arrow in the figure).
Further, the horizontal conveyors 5 and 6 have the horizontal conveyor surfaces 5a and 6a with reference to the conveyor surfaces 1a and 1b with the blades 9c facing downward so that the impeller 9 does not get over the horizontal conveyors 5 and 6. It is sufficiently higher than the height of the impeller 9.

These horizontal conveyors 5 and 6 prevent the impeller 9 from falling from the conveyor surface 1a, and, as will be described later, dissociate a plurality of interfering impellers 9 and move them individually. ing.
Here, the interfering impellers 9 are less likely to dissociate when the shortest distance between the horizontal conveyor surfaces 5a and 6a and the leading ends 2aa and 3aa of the opposing guide surfaces 2a and 3a is increased, and when the distance is reduced, the intervals are increased. It becomes easy to close.
Therefore, the shortest distance between the horizontal conveyor surfaces 5a and 6a and the leading ends 2aa and 3aa in the extending direction of the guide surfaces 2a and 3a is such that the impellers 9 move separately and dissociate the impellers 9 that have interfered. The outer diameter is preferably exceeded and less than twice the outer diameter of the impeller 9.

Moreover, if the moving speed of the horizontal conveyor surfaces 5a and 6a is made faster than the moving speed of the conveyor surface 1a, the interfering impeller 9 can be more reliably dissociated, but the impeller 9 moves upstream against the movement of the conveyor surface 1a. It may move and fall from the side edge 1aa of the conveyor surface 1a over the horizontal conveyor surfaces 5a and 6a.
In such a case, it is preferable to arrange a gathering portion 10 as shown in FIG. The gathering portion 10 has a gathering surface 10a substantially perpendicular to the conveyor surface 1a, and the gathering surface 10a is inclined with respect to the moving direction of the conveyor surface 1a. Thereby, the impeller 9 can be moved to the center direction of the conveyor surface 1a, and the impeller 9 can be prevented from falling.

  The horizontal conveyor surfaces 5a and 6a are preferably surfaces on which the impeller 9 is difficult to slip. For example, the conveyor surfaces 1a and 1b are preferably rubber surfaces. By doing in this way, the several impeller 9 which interfered can be made easy to dissociate. The dissociation of the interfering impellers 9 will be described in detail later.

  Moreover, since the fall of the impeller 9 from the conveyor surface 1a can be prevented even if the horizontal conveyors 5 and 6 are simple plates along the side edges 1aa of the conveyor surface 1a, the horizontal conveyors 5 and 6 May be replaced. However, the horizontal conveyors 5 and 6 are preferable because they have an action of dissociating the impellers 9 that interfere with each other.

(Sensor unit)
The apparatus of the present invention preferably has a sensor unit 7 as shown in FIG. The sensor unit 7 is disposed at a position where the impeller 9 is transferred from the conveyor 1a to the conveyor 1b, the photoelectric sensor 7a is disposed at the side end 1aa at the downstream end of the conveyor surface 1a, and the upstream end side of the conveyor surface 1b. A photoelectric sensor 7b is arranged at the end 1ba. And the photoelectric sensor 7a detects the impeller 9 just before the conveyor 1a delivers to the conveyor 1b, and the photoelectric sensor 7b detects the impeller 9 just after the conveyor 1a delivers to the conveyor 1b. The sensor unit 7 is connected to the control unit 8.

(Control part)
The apparatus of the present invention preferably has a control unit 8 as shown in FIG. The control unit 8 is connected to the motor 1 c that drives the conveyor surface 1 a and the sensor unit 7. And the control part 8 judges the presence or absence of the impeller 9 in the downstream end of the conveyor surface 1a, and the upstream end of the conveyor surface 1b from the detection signal of the sensor unit 7, and according to the judgment, the motor 1c The drive is controlled to enable intermittent movement of the conveyor 1a.

Next, the operation in which the apparatus of the present embodiment aligns the posture of the impeller 9 will be described according to the posture of the impeller 9 while separating the cases.
First, when the plurality of impellers 9 are placed upstream of the conveyor surface 1a in a state where the conveyor is driven, the plurality of impellers 9 reach the guide member 2 after moving together with the conveyor surface 1a. And the form of the impeller 9 in that case has the case where it reaches | attains the guide member 2 in the state which reaches | attains the guide member 2 separately, and a plurality interferes.

First, the case where the impeller 9 reaches the guide member 2 individually will be described.
When the impeller 9 that has reached individually has a posture in which the blade 9c faces upward as shown in FIG. 2A, the impeller 9 that has reached the guide member 2 has a blade as shown in FIG. It moves while rotating along the guide surface 2a with 9c facing upward. The impeller 9 moves away from the guide surface 2a at the tip 2aa and moves together with the conveyor surface 1a with the blades 9c facing upward.
Thereafter, the impeller 9 reaches the guide member 3 and moves along the guide surface 3a with the blades 9c facing upward as in the case of reaching the guide member 2. The impeller 9 moves away from the guide surface 3a at the tip 3aa and moves to the downstream end of the conveyor surface 1a with the blades 9c facing upward.

  When the impeller 9 reaches the downstream end of the conveyor surface 1a, the impeller 9 is transferred to the conveyor surface 1b by intermittent movement of the conveyor surface 1a as shown in FIG.

  As shown in FIG. 5A, when the conveyor 1a delivers the preceding impeller 9 'to the conveyor 1b, the photoelectric sensors 7a and 7b detect the delivery, and the control unit 8 outputs the detection signal. receive. As shown in FIG. 5B, when the trailing impeller 9 reaches the downstream end of the conveyor 1a, the control unit 8 receives a detection signal from the photoelectric sensor 7a and drives the conveyor surface 1a. 1c is stopped, and as shown in FIG. 5C, the impeller 9 is made to stand by at the position of the photoelectric sensor 7a, that is, at the downstream end of the conveyor surface 1a. And after making the following impeller 9 wait for the time which does not contact preceding impeller 9 ', the control part 8 drives the motor 1c again, moves the conveyor surface 1a, FIG.5 (d). As shown, the impeller 9 is transferred to the upstream end of the conveyor 1b.

  As described above, the control unit 8 controls the driving of the motor 1c and intermittently moves the conveyor surface 1a, so that the impeller 9 reaches the guide member 4 with a front-rear interval. Then, the impeller 9 that has reached the guide member 4 moves along the guide surface 4a with the blades 9c facing upward, away from the guide surface 4a at the tip 4aa, and with the blades 9c facing upward, the conveyor 1a It is discharged at the downstream end.

Next, the case where the posture of the impeller 9 that individually reaches the guide member 2 is a posture in which the blades 9c face downward as shown in FIG. 2B will be described.
In this case, as shown in FIG. 6, the impeller 9 that has reached the guide member 2 rotates along the guide surface 2a and reverses the blades 9c from downward to upward. FIG. 7 is a view of the reversal of the impeller 9 in FIG. 6 as seen from the width direction of the conveyor surface 1a. The posture of the impeller 9 from FIG. 7 (a) to FIG. This corresponds to the postures (a) to (e) in FIG.

First, as shown in FIG. 7A, the impeller 9 moves in the moving direction of the conveyor surface 1a together with the conveyor surface 1a with the blades 9c facing downward, and reaches the guide member 2 to reach the guide surface 2a. Contact. Then, as shown in FIG. 7B, when the conveyor 1a further moves, the contact point P1 between the impeller 9 and the conveyor surface 1a moves in the direction of the guide surface 2a, and the contact point P between the blade 9c and the guide surface 2a. Becomes higher. The impeller 9 is raised in a direction in which the shaft 9b is horizontal with the conveyor surface 1a, and rotates in the direction of the dotted arrow while moving along the guide surface 2a.
If the conveyor surface 1a has an upward slope with respect to the moving direction, the impeller 9 is not slippery, or the guide surface 2a is slippery, the impeller 9 can move smoothly. Thus, the impeller 9 is likely to take a posture.

Then, as shown in FIG. 7C, when the impeller 9 is in a posture in which the shaft 9b is horizontal with the conveyor surface 1a, as shown in FIG. The blade 9c is turned upward as shown in FIG. 7 (e).
The impeller 9 with the blades 9c facing upward moves while rotating along the guide surface 2a. At the tip 2aa, the impeller 9 moves away from the guide surface 2a, and with the blades 9c facing upward, in the moving direction of the conveyor 1 together with the conveyor 1a. Moving.
Thereafter, the impeller 9 moves in the same manner as when reaching the guide member 2 with the blades 9c facing upward, and is discharged to the downstream end of the conveyor 1a.

Next, the case where the posture of the impeller 9 that individually reaches the guide member 2 is a posture in which the blades 9c face downward as shown in FIG. 2 (c) will be described.
In this case, as shown in FIG. 8A, when the impeller 9 reaches the guide member 2 by the movement of the conveyor 1a, the contact point P1 between the impeller 9 and the conveyor surface 1a moves in the direction of the guide surface 2a. Then, the impeller 9 falls and the hub 9a is inclined with respect to the conveyor surface 1a as shown in FIG. 8 (b). If the conveyor surface 1a is a non-slip surface and the guide surface 2a is a non-slip surface, the impeller 9 is more likely to fall.

Thereafter, as shown in FIGS. 6 and 7, the impeller 9 rotates along the guide surface 2a, reverses the blade 9c from downward to upward, and then moves while rotating along the guide surface 2a. . The impeller 9 moves away from the guide surface 2a at the tip 2aa, and moves in the moving direction of the conveyor 1 together with the conveyor 1a, with the blades 9c facing upward.
Thereafter, the impeller 9 moves in the same manner as when it reaches the guide member 2 with the blades 9c facing upward, and is discharged to the downstream end of the conveyor 1a.

Next, a case where a plurality of impellers 9 interfere and reach the guide member 2 will be described.
In this case, movement of the interfering impellers 9 is restricted, and the impellers 9 to be reversed may not be reversed even if they contact the guide surface. In that case, the plurality of impellers 9 move along the guide surface 2a while interfering with each other and reach the tip 2aa.

In the plurality of impellers 9 that have reached the tip 2aa, the shortest distance between the horizontal conveyor surface 5a and the tip 2aa is set to exceed the outer diameter of the impeller 9 and less than twice the outer diameter of the impeller 9. As a result, as shown in FIG. 9A, a part of the impeller 9 that has interfered contacts the horizontal conveyor surface 5a. And since the moving direction of the horizontal conveyor surface 5a is opposite to the moving direction of the conveyor surface 1a, as shown in FIG.9 (b), the impeller 9 which contacted the horizontal conveyor surface 5a moved the conveyor surface 1a. The impeller 9 that moves in the direction opposite to the direction and does not contact the horizontal conveyor surface 5a moves in the moving direction of the conveyor surface 1a, and the plurality of impellers 9 that have interfered with each other are dissociated.
The impeller 9 dissociated and separated passes between the horizontal conveyor surface 5a and the tip 2aa and moves with the conveyor surface 1a, or is in contact with the horizontal conveyor surface 5a and in the opposite direction to the conveyor surface 1a. Move to. The impeller 9 moved together with the conveyor surface 1a individually reaches the guide member 3, and contacts the guide surface 3c in the same manner as when individually reaching the guide member 2, with the blades 9c facing upward, It reaches the downstream end of 1a. And the impeller 9 which moved to the reverse direction to the conveyor surface 1a moves to the center side of the conveyor surface 1a by destroying an attitude | position in the case of a movement. Moreover, when arranging the approach part 10, it contacts the approach surface 10a and moves to the center side of the conveyor surface 1a. And the impeller 9 which moved to the center side of the conveyor surface 1a moves with the conveyor surface 1a, and obtains the opportunity to contact the guide surface 2a again.

  On the other hand, even if it passes between the front-end | tip 2aa and the conveyor surface 5a, the some impeller 9 with insufficient dissociation moves along the guide surface 3a, interfering. And when reaching the tip 3aa of the guide surface 3a, the setting of the interval between the horizontal conveyor surface 6a and the tip 3aa, that is, the interval exceeding the outer diameter of the impeller 9 and less than twice the outer diameter of the impeller 9 A part of the impeller 9 that has interfered contacts the horizontal conveyor surface 6a. And since the moving direction of the horizontal conveyor surface 6a is reverse to the moving direction of the conveyor surface 1a, the impeller 9 which contacted the horizontal conveyor surface 6a is moved in the direction opposite to the moving direction of the conveyor surface 1a, and the horizontal conveyor surface The impeller 9 which does not contact 6a is moved in the moving direction of the conveyor 1a, and the plurality of impellers 9 that have been insufficiently dissociated are completely dissociated. And the impeller 9 which became individual by dissociation moves with the conveyor surface 1a, and reaches the downstream end of the conveyor 1a.

  In addition, if the horizontal conveyor surfaces 5a and 6a are surfaces on which the impeller 9 is difficult to slip, the impeller 9 in contact with the horizontal conveyor surfaces 5a and 6a easily moves in the direction opposite to the moving direction of the conveyor 1a. The plurality of impellers 9 are easily dissociated.

The impellers 9 that individually reach the downstream end of the conveyor surface 1a are transferred to the conveyor surface 1b. And the impeller 9 which moved the conveyor surface 1b and reached | attained the guide member 4 is discharged | emitted from the downstream of the conveyor surface 1b, with the blade | wing 9c facing upward similarly to the case where it reaches | attains the guide member 2 separately. The
In addition, when delivering the impeller 9 from the conveyor surface 1a to the conveyor surface 1b, the sensor unit 7 and the control unit 8 can intermittently move the conveyor 1a to deliver the impeller 9 at intervals. it can. Thereby, the impeller 9 reaches the guide member 4 reliably and individually, and the impeller 9 with the blades 9c facing downward is reliably reversed and discharged from the downstream side of the conveyor surface 1b.

As described above, the apparatus according to the present embodiment has the blade 9c regardless of whether the impellers 9 individually reach the guide member 2 or a plurality of impellers 9 interfere with each other. Can be discharged from the downstream side of the conveyor surface 1b.
And the apparatus of this embodiment can align the attitude | position of the impeller 9 easily, without requiring the fine adjustment of an apparatus like the above description.

[Second Embodiment]
Next, a second embodiment of the impeller attitude alignment device of the present invention will be described. The apparatus of the second embodiment is obtained by adding a protrusion to the apparatus of the first embodiment, and a description of the entire apparatus is omitted. And in drawing of description, the same code | symbol is attached | subjected about the same structure as 1st Embodiment.

  In the apparatus of the first embodiment, if the shaft 9b of the impeller 9 is long, it may be difficult to reverse. As shown in FIG. 10 (a), the impeller 9 having a long shaft 9b moves with the conveyor 1a to reach the guide member 2, and attempts to take a posture as shown in FIG. 10 (b). This is because the center of gravity is shifted to the shaft 9b side, so that the contact point P does not slide more than a certain height, and a rotational moment about the contact point P1 cannot be obtained sufficiently. The impeller 9 that cannot be reversed rotates in the direction of the dotted arrow in the posture as shown in FIG. 10C, and is rotated by the action of the conveyor surface 1a that attempts to move in the downstream direction along the guide surface 2a. The action of the user trying to move in the upstream direction of the conveyor surface 1a becomes dominant, and moves along the guide surface 2a in the direction opposite to the moving direction of the conveyor surface 1a. When the impeller 9 moves in this way, the impeller 9 is not transported in the moving direction of the conveyor surface 1a and is stagnated in the vicinity of the guide surface 2a.

Therefore, in the apparatus according to the present embodiment, as shown in FIG. 11, a protrusion 2c having a return surface 2d is provided on the guide surface 2a. Although not shown in the drawings, similar protrusions are provided on the guide surfaces 3a and 4a.
The protrusion 2c makes the return surface 2d substantially perpendicular to the guide surface 2a and the conveyor surface 1a. The vertical length of the return surface 2d with respect to the guide surface 2a is longer than the length sufficient to guide the sliding up of the shaft 9b when the impeller 9 is reversed, and the blade 9c contacts the protrusion 2c. The length is set to be less than the length to prevent the impeller 9 from being reversed. And the protrusion part 2c is made to provide in the base end side of the guide member 2, ie, the side end 1aa of a conveyor surface, so that the movement of the other impeller 9 may not be prevented.

  As shown in FIG. 11, when the protrusion 2c is provided, even if the impeller 9 moves along the guide surface 2a in the direction opposite to the moving direction of the conveyor surface 1a, the shaft 9b contacts the protrusion 2c. The movement is blocked. Then, the impeller 9 can slide the shaft 9b along the return surface 2d, and can reverse the blade 9c upward by the rotational moment about the contact P1.

  As described above, by using the apparatus of the present embodiment, even if the impeller 9 has a long shaft 9b, the posture can be easily aligned without adjusting the apparatus.
