DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a blow cylinder that constitutes a conveyance air path (passage) of a conveyance device H that conveys a conveyance target T such as feed, buckwheat, soybeans, azuki beans, and wheat. Yes, a blower (not shown) is connected to the end of the blow tube 1.
The blower is a well-known one, and is configured to rotate a fan (not shown) so as to suck air from one side of the blower and exhaust it to the other. One end of the blowing cylinder 1 is connected to the mouth (not shown), and a conveying air passage is formed in the blowing cylinder 1 through which a suction air or a compressed air conveying air flows.
In order to facilitate understanding, the configuration may be described using directions such as up and down, left and right, but the configuration of the present invention is not limited thereby.

The blower cylinder 1 conveys the conveyance object T by the conveyance air flowing from the upper side to the lower side in the conveyance direction, and a conveyance object separation unit 3 that separates the conveyance object T from the conveyance air at a predetermined intermediate position of the blower cylinder 1. Provide.
The conveyed product separating section 3 is provided with an opening 4 at a predetermined intermediate position of the blower cylinder 1 (FIG. 2), and the opening 4 is connected to the base of the wind branch pipe 5 so The cylinder 1 is a conveyance cylinder 6, and the blower cylinder 1 on the lower conveyance side of the opening 4 is a conveyance object reduction cylinder 7.
A derivative 8 for narrowing the inner diameter of the transfer cylinder 6 is provided in the transfer cylinder 6 facing the opening 4, and a guide pipe 9 for naturally dropping the transfer object T is connected to the end of the transfer object deceleration cylinder 7, A discharge mechanism 10 that discharges (feeds out) the object T to be conveyed while blocking the entry and exit of air is provided at the end of the guide tube 9, thereby configuring the conveyed object separation unit 3.

As shown in FIG. 2, the transported object separating unit 3 has a normal transport range in which the transport target T is transported at a constant speed to the base of the derivative 8 of the transport cylinder 6, and the tip of the derivative 8 from the base of the derivative 8. Up to the acceleration range in which the small diameter portion 11 in which the inner diameter of the conveyance cylinder 6 is narrowed and the flow velocity of the conveying air is accelerated from the small diameter portion 11 to accelerate the conveyance speed of the conveyance target T is conveyed in the acceleration range. By increasing the inertial force of the object T, the opening 4 is allowed to pass and the conveying air and the conveying object T are separated.
Next, the conveyed product deceleration cylinder 7 is set to a deceleration range from the tip of the derivative 8, and in the deceleration range, the lower side of the conveyed product deceleration cylinder 7 is closed by the discharge mechanism 10, and the conveyance wind returns to the opening 4 to return to the wind. Since it flows into the branch pipe 5, the conveyance target T that has passed through the opening 4 is moved to the lower side while being decelerated by the return air returning to the opening 4.

That is, as shown in FIG. 2, since the transported air that has passed through the derivative 8 is blocked by the discharge mechanism 10 in the transported object deceleration cylinder 7 and the guide tube 9, the derivative 8 is inserted into the transported object deceleration cylinder 7 in the deceleration range. The forward conveying air that flows under the tip and the return air that is blocked by the discharge mechanism 10 and loses the destination and returns toward the opening 4 in the opposite direction in the conveyed material decelerating cylinder 7 are two layers, upper and lower. And flows in directions opposite to each other, and imparts resistance to the transport speed of the transport object T by the viscous shearing force of air and decelerates.
For this reason, the transport air and the transport object T are separated by the transport object separation unit 3 and the moving speed of the transport object T is reduced.

In other words, the wind speed is faster than the conveyance speed up to an acceleration range where the derivative 8 is present, but in the deceleration range, the conveyance speed becomes faster than the wind speed in the wind branch pipe 5 and the conveyance object deceleration cylinder 7 due to the viscous shear force of the air. The moving speed of the transport target T is reduced while separating the air and the transport target T.
Therefore, the distance that the conveyance target T can move is determined by the relative relationship between the diameter of the small-diameter portion 11 and the air volume flowing through the small-diameter portion 11, and the internal diameter and the length of the conveyance-object deceleration cylinder 7 are determined by this relative relationship. What is necessary is just to set this to the predetermined length which the conveyance target T can move from the small diameter part 11 to the guide tube 9.

For example, when the air volume in the transfer cylinder 6 increases due to transfer conditions, the diameter of the small diameter portion 11 is reduced by increasing the cross-sectional area of the derivative 8 with respect to the inner diameter of the transfer cylinder 6 to increase the wind speed. At the same time, the inner diameter of the conveyed product deceleration cylinder 7 is increased or the length thereof is increased.
On the other hand, when the air volume in the transfer cylinder 6 decreases due to the transfer conditions, the diameter of the small diameter portion 11 is increased by reducing the cross-sectional area of the derivative 8 with respect to the inner diameter of the transfer cylinder 6 to increase the wind speed. The inner diameter of the conveyed product deceleration cylinder 7 is the same as that of the conveyance cylinder 6 or the length thereof is shortened.

Further, the length of the transported object speed reduction cylinder 7 between the opening 4 and the guide pipe 9 is relatively determined by the relationship between the sectional area of the derivative 8 relative to the inner diameter of the transport cylinder 6 and the air volume. Based on the moving distance of the object T, by setting the length of the conveyed object decelerating cylinder 7 slightly shorter than this moving distance, it is possible to prevent clogging while reducing the moving speed of the conveyed object T, which is preferable. It is.
A plurality of different derivatives 8 having different cross-sectional areas with respect to the inner diameter of the transfer cylinder 6 are prepared, and can be selectively attached according to the air volume in the transfer cylinder 6, and the derivative 8 is replaced. Accordingly, the transport target T is separated from the transport wind and can be reliably moved to the guide tube 9 to prevent clogging, which is preferable.

In addition, since the inertia force of the movement of the transport target T is lost in the guide tube 9, the guide tube 9 is arranged so as to tilt vertically or beyond the angle of repose in order to move the transport target T smoothly. .
Further, the discharge mechanism 10 may be a so-called rotary valve that can feed out the transport target T without leaking air, or alternatively, the transport target T can be fed out by alternately opening and closing two shutters. The discharge amount is set to be equal to or more than the transport amount of the transport target T.

Although a device for the next process is provided on the lower side of the discharge mechanism 10, it is not a requirement of the present application, and details thereof are omitted. For example, when brown rice is conveyed, a rice milling device is provided on the lower side of the discharge mechanism 10. When the white rice is conveyed, the rice cooker is arranged.
For the sake of easy understanding, FIG. 1 shows the derivative 8 with the opening 4 and the wind branch pipe 5 positioned on the upper side of the blower cylinder 1. The shape of the derivative 8 is shown in FIG. The upper and lower directions are shown and described below, but the configuration of the present invention is not limited thereby.

The shape of the derivative 8 is arbitrary as long as the inner diameter of the small diameter portion 11 provided with the derivative 8 is narrowed to the upper side in the conveyance direction of the derivative 8, and the shape is arbitrary. The upper surface (opening 4 side) is formed in a circular arc portion 14 aligned with the inner surface of the transfer cylinder 6 (FIG. 3), and the lower surface (opposite opening 4 side) is in front of the transfer cylinder 6 in the side view (transport direction). The upper surface is close to the upper inner surface of the transfer cylinder 6 and is formed on an inclined surface 15 that is inclined so as to approach the axial center of the transfer cylinder 6 as the opening 4 is approached.
That is, the inclined surface 15 is inclined in a direction away from the opening 4 as it approaches the opening 4.

Therefore, the derivative 8 narrows the inner diameter of the blow cylinder 1 and expects the transport object T to be guided so as to move on the opposite side of the wind branch pipe 5, so that the transport object T and the transport wind are separated. Make good.
Further, when the front end position of the derivative 8 faces the transporting object decelerating cylinder 7 side of the opening 4, the guiding of the transporting object T in the moving direction and the action of preventing the transporting object T from entering the wind branch pipe 5 are further enhanced. Can be improved.
The derivative 8 is attached to the conveying cylinder 6 by an attachment shaft 16. The mounting shaft 16 is inserted into a long hole 17 provided in the conveying cylinder 6 so as to be movable in the axial direction of the blower cylinder 1, and the positional relationship between the tip of the derivative 8 and the opening 4 can be adjusted.

Therefore, the conveyance target T is prevented from entering the wind branch pipe 5.
Further, the blower cylinder 1 of the present example has the conveyance cylinder 6 and the conveyance object speed reduction cylinder 7 arranged in a straight line, so that the conveyance object T enters the conveyance object deceleration cylinder 7 from the conveyance cylinder 6 smoothly and reliably. Improves sex.
Therefore, when the transport target T is transported through the blower cylinder 1 by suction air, the intrusion of air cannot be completely blocked by the discharge mechanism 10, so that the intruded air is transported by the transport air in the transport object deceleration cylinder 7. May adversely affect flow.
Therefore, the bypass tube 20 is connected to the guide tube 9 so that air can escape.
Reference numeral 21 denotes a valve provided in the bypass cylinder 20.

Further, the conveyed product deceleration cylinder 7 may be formed with a diameter larger than a predetermined diameter without providing the bypass cylinder 20.
Moreover, since the wind branch pipe 5 should just be connected to the opening part 4 of the ventilation cylinder 1, the direction of the length direction of the wind branch pipe 5 is arbitrary, and as shown in FIG. In addition to providing the wind branch pipe 5 orthogonally to 7, it may be provided obliquely with respect to the transport cylinder 6 and the transported object reduction cylinder 7 as shown in FIGS. 4 and 5.
Moreover, the height of the front end side of the wind branch pipe 5 may be any direction up and down (high and low) with respect to the installation height of the base.

(Operation of the embodiment)
The present invention is configured as described above, and when the blower is started and the conveyance target T is supplied to the blower cylinder 1, the blower cylinder 1 conveys the conveyance target T by the conveyance wind flowing from the upper side to the lower side in the conveyance direction. .
Since the transport object separating unit 3 that separates the transport object T from the transport air is provided at an intermediate predetermined position of the blow cylinder 1, the transport object T that is transported by the blow cylinder 1 is transported by the transport object separating unit 3. It is separated from the conveyance wind and reaches the conveyance destination.

  The conveyed product separating unit 3 is provided with an opening 4 in which the base of the wind branch pipe 5 is connected at a predetermined intermediate position of the blower cylinder 1, and the blower cylinder 1 on the upper transfer side of the opening 4 is used as a transfer cylinder 6. 4 is formed on the conveyance speed reducing cylinder 7, and a derivative 8 for narrowing the inner diameter is provided in the conveyance cylinder 6 facing the opening 4, and on the lower side of the conveyance speed reduction cylinder 7. Since the discharge mechanism 10 that cuts off the air and discharges the conveyance target T is provided, the conveyance target T reaches the small-diameter portion 11 of the blower cylinder 1 provided with the derivative 8. , And the conveyance speed of the conveyance object T is accelerated by increasing the flow velocity of the conveyance air at the small diameter portion 11 whose inner diameter is narrowed by the derivative 8, and enters the conveyance object decelerating cylinder 7 to be conveyed. It moves further due to inertial force.

On the other hand, as shown in FIG. 2, since the conveyed product reduction cylinder 7 and the guide tube 9 are closed by the discharge mechanism 10, the conveyance air that has passed through the derivative 8 is temporarily conveyed directly below the derivative 8 from the lower part of the derivative 8. The air that flows through the lower layer in 7 but is blocked by the discharge mechanism 10 and has no destination becomes the return wind that returns to the wind branch pipe 5 through the upper layer in the conveyed product deceleration cylinder 7.
Therefore, since the lower layer conveying wind and the upper layer returning wind in the conveyed product decelerating cylinder 7 flow in opposite directions and the lower layer conveying wind gradually decelerates, the conveying object T is separated from the conveying wind. Thus, the conveyance wind and the conveyance object T are separated by moving in the conveyance object deceleration cylinder 7 by inertia.

Further, the conveying wind and the object to be conveyed T are separated by the upper return air in the object to be conveyed decelerating cylinder 7, and the moving speed of the object to be conveyed T is resisted by the viscous shear force of the air in the object to be decelerating cylinder 7. Give and slow down.
The conveyance object T decelerated in the conveyance object decelerating cylinder 7 enters the guide tube 9 and is discharged by the discharge mechanism 10.
Therefore, the conveyed product separating unit 3 is provided with the opening 4 in the middle of the blower cylinder 1, the base of the wind branch pipe 5 is connected to the opening 4, the derivative 8 is provided in the blower cylinder 1 of the opening 4, and the opening It is possible to configure simply by providing the discharge mechanism 10 on the lower side of the conveyed product deceleration cylinder 7 on the lower side of the part 4, and it can be configured simply.

In other words, the conveying cylinder 6, the conveyed product deceleration cylinder 7, and the wind branch pipe 5 as the blower cylinder 1 have existed conventionally, and the discharge mechanism 10 provided on the lower side of the conveyed article deceleration cylinder 7 has a special configuration. Although it is unnecessary, the transported object separating unit 3 can be configured only by providing the derivative 8 in the opening 4 of the blower cylinder 1 and appropriately arranging the wind branch pipe 5 and the transported object decelerating cylinder 7. It can be installed in the middle of the blow tube 1 and the degree of freedom in selecting the installation location can be improved.
Moreover, since the moving distance of the conveyance target T that has passed through the tip of the derivative 8 is determined by the relationship between the sectional area of the derivative 8 with respect to the inner diameter of the conveyance cylinder 6 and the air volume, the conveyance assumed thereby Setting the length of the transport object decelerating cylinder 7 slightly shorter than the travel distance based on the travel distance of the object T is preferable because it can prevent clogging while reducing the travel speed of the transport object T. is there.

Since the derivative 8 has a structure in which a plurality of different cross-sectional areas occupying the inner diameter of the transfer cylinder 6 are prepared and can be selectively attached depending on the air volume in the transfer cylinder 6, the derivative 8 is By exchanging, it is preferable because the moving distance of the conveyance target T can be secured and clogging can be prevented.
In addition, since the guide tube 9 is arranged vertically or tilted beyond the angle of repose, even if the inertia force for moving the object T to be transported by the transport object deceleration cylinder 7 is attenuated, the guide tube 9 reaches the guide tube 9. If it falls, it will be reliably supplied to the discharge mechanism 10 by the guide tube 9, and clogging can be prevented.

Further, since the transport object T is separated from the transport air by the transport object separation unit 3 and reaches the guide pipe 9 due to inertia, the transport speed of the transport object T is reduced, and the transport object deceleration cylinder 7 and the guide pipe 9 are reduced. It is prevented from colliding with the inner surface of the connecting portion with the, and the damage to the transport object T is suppressed.
Further, since the discharge mechanism 10 is set so that the discharge amount is equal to or greater than the transport amount of the transport target T by the transport cylinder 6, it is possible to prevent clogging.

  Thus, the shape of the derivative 8 is arbitrary, but in this embodiment, the upper surface (opening 4 side) of the derivative 8 is formed in an arc portion 14 that matches the inner surface of the transfer cylinder 6 and the lower surface (anti-opening portion). 4 side) is inclined so that the front side (upper side in the transport direction) of the transfer cylinder 6 is close to the upper inner surface of the transfer cylinder 6 in a side view and approaches the axis of the transfer cylinder 6 as the opening 4 is approached. Since it forms in the inclined surface 15, the internal diameter of the cylinder 6 for conveyance can be made narrow as it approaches the opening part 4, and the conveyance speed of the conveyance target T is accelerated, and also the conveyance target T by the inclined surface 15 of the derivative | guide_body 8. Is guided so as to move on the opposite side of the wind branch pipe 5, and the separation of the transport object T and the transport wind is improved.

Further, since the tip position of the derivative 8 faces the side of the transported object decelerating cylinder 7 of the opening 4, further guidance of the moving direction of the transported object T and entry of the transported object T into the wind branch pipe 5 are achieved. Improve the prevention effect.
Further, the blower cylinder 1 of the present example has the conveyance cylinder 6 and the conveyance object speed reduction cylinder 7 arranged in a straight line, so that the conveyance object T enters the conveyance object deceleration cylinder 7 from the conveyance cylinder 6 smoothly and reliably. Improves sex.

In the description of the above-described embodiment, directions such as up, down, left, and right are described for easy understanding, but this is for convenience and the configuration is not limited by these descriptions.
For example, the installation direction of the derivative 8 varies depending on the axial direction of the wind branch pipe 5, and the arc portion 14 is not necessarily formed on the upper surface of the derivative 8 and may be formed on the side surface or the lower surface.
