Reference numeral 1 denotes a blower cylinder that constitutes a transport passage of a transport device H that transports a transport target T such as feed, buckwheat, soybeans, azuki beans, and rice wheat. The blower 2 is connected to the end of 1.
The blower 2 is a well-known one, and is configured to rotate a fan (not shown) to suck air from one side of the blower 2 and exhaust it to the other. The suction unit 3 of the blower 2 is connected to the end of the blower cylinder 1 to form a suction conveyance air passage. Reference numeral 5 denotes an exhaust port of the blower 2, and an exhaust hose 6 is connected to the exhaust port 5.

Although not shown, a tension shutter that opens and closes the connection is provided between the blower cylinder 1 and the tension hopper 10.
The blower cylinder 1 between the blower 2 and the tension hopper 10 is provided with a conveyance object separation device 15 that separates the conveyance target T from the tension hopper 10 from the conveyance air. On the lower conveyance side of the conveyed product separating apparatus 15, a conveying apparatus 16 for separately conveying the separated conveyance target T is provided. Since the transfer device 16 is a transfer means to the next process and is not a requirement of the present application, details are omitted. The conveying device 16 is configured to convey to the rice milling process when, for example, brown rice is introduced into the tension hopper 10, and to the rice cooking process when white rice is introduced into the tension hopper 10.

  A transport cylinder 21 of the blower cylinder 1 that transports the transport object T from the tension hopper 10 is connected and fixed to the tank (receiver tank) 20 of the transport object separating device 15. An exhaust cylinder 23 of the blower cylinder 1 is connected to an exhaust port 22 provided in the tank 20. The tank 20 is formed to have a relatively large capacity (large volume) with respect to the transport cylinder 21 and attenuates the wind pressure and the wind speed, which are pressures applied to the object of the transport wind flowing in from the transport cylinder 21, so that the transport object T Is separated from the conveying air.

That is, the wind pressure / velocity becomes stronger (faster) when the passage area of the air passage becomes narrower and weaker (slower) when the passage area becomes wider, so that the tank 20 has a relatively large volume (capacity) relative to the diameter of the transport cylinder 21. In order to attenuate the wind pressure and speed of the conveying wind blown from the conveying cylinder 21 until the conveying object T is substantially separated from the conveying wind.
The transport cylinder 21 in front of the tank 20 is provided with a speed reduction unit 25 that slows the transport speed (wind speed) due to the transport wind. The speed reduction part 25 suppresses that the conveyance target T which enters into the tank 20 collides with the inner surface of the tank 20, and is damaged by making conveyance speed slow.
The speed reduction unit 25 is configured by connecting and connecting a transport cylinder 21 and an exhaust cylinder 23 at a predetermined position in front of the tank 20 by a communication cylinder 26.

One end 27 of the communication cylinder 26 is connected to the transport cylinder 21 in front (upper side) of the tank 20, and the transport cylinder 21 between the one end side connection port 28 between the communication cylinder 26 and the transport cylinder 21 and the tank 20 is connected. The portion is made a decelerating conveyance cylinder part 29, and the conveyance speed (wind speed) of the decelerating conveyance cylinder part 29 is made slower than the conveyance speed (wind speed) of the conveyance cylinder 21 up to the one end side connection port.
That is, by connecting the transport cylinder 21 to the exhaust cylinder 23 by the communication cylinder 26 without passing through the tank 20, the exhaust cylinder 23 sucks the inside of the transport cylinder 21 through the communication cylinder 26 and is connected to one end side. The communication tube 26 and the decelerating and conveying cylinder portion 29 are branched at the opening 28, and the conveying speed in the decelerating and conveying cylinder portion 29 is reduced as compared with the conveying cylinder 21.

30 is a connection port between the other end of the communication tube 26 and the exhaust tube 23, and 31 is an exhaust tube portion between the tank 20 and the connection port 30.
A communication opening / closing valve 35 is provided in the communication cylinder 26 on the upper side of the connection port 30. The communication opening / closing valve 35 is tightened when the conveyance object T enters the communication cylinder 26 from the one end side connection port 28, and the conveyance object T is discharged out of the apparatus by reducing the wind pressure / velocity in the communication cylinder 26. Is prevented.

  An exhaust adjustment valve 36 is provided at a predetermined position of the exhaust cylinder portion 31 on the upper side of the connection port 30. The wind pressure and wind speed in the communication cylinder 26 vary depending on conditions such as the diameter and length of the transport cylinder 21, the exhaust cylinder 23, and the communication cylinder 26, and the communication depends on the shape and specific gravity of the transport object T. Even when the opening / closing valve 35 is fully opened, when the conveyance speed in the deceleration conveyance cylinder portion 29 is not sufficiently reduced, the exhaust adjustment valve 36 is throttled to increase the wind speed in the communication cylinder 26, thereby reducing the deceleration conveyance cylinder. The conveyance speed (wind speed) in the unit 29 is reduced.

Configuration of communication on-off valve 35 and the exhaust control valve 36 is optional, configuration der Re Bayoku that can change adjust the wind velocity by varying the cylinder inner diameter, for example, attaching a pivotal plate 37 in the regulation shaft 38, adjustment shaft 38 may be rotatably attached to the communication cylinder 26 and the exhaust cylinder portion 31. Reference numeral 39 denotes an adjustment dial.
An intrusion prevention body 40 that prevents the conveyance target T from entering the communication cylinder 26 is provided in the conveyance cylinder 21 on the upper side of the one end side connection port 28.

It forms in the inclined surface 42 inclined so that it might approach the axial center of the conveyance cylinder 21 as it approaches the side connection port 28.

That is, the inclined surface 42 is inclined in a direction away from the opening of the one end side connection port 28 as it approaches the one end side connection port 28.
Therefore, the conveyance target T in the conveyance cylinder 21 is guided in a direction away from the one end side connection port 28 by the inclined surface 42 of the intrusion prevention body 40, passes through the one end side connection port 28, and passes through the deceleration conveyance cylinder unit 29. Through the tank 20.
The tip of the intrusion prevention body 40 is positioned so as to face the tank 20 side of the one end side connection port 28.

Therefore, in the conveyance cylinder 21 on the upper side of the one end side connection port 28, the passage area of the air passage is narrowed by the intrusion prevention body 40, so that the wind pressure and the wind speed are strong (fast), and the position where the one end side connection port 28 faces. Then, once the conveyance target T moves quickly, it is prevented from being discharged out of the apparatus.
Then, after passing through the one end side connection port 28, the conveyance target T is decelerated by the deceleration conveyance cylinder portion 29 and enters the tank 20.
Therefore, by causing the tip of the intrusion prevention body 40 to face the tank 20 side of the one end side connection port 28, the action of guiding the moving object T in the moving direction and preventing the discharge from outside the apparatus are exhibited.

Reference numeral 43 denotes an attachment shaft for attaching the intrusion prevention body 40 to the transport cylinder 21. The intrusion prevention body 40 is attached to the long hole 44 provided in the transport cylinder 21 so as to be movable in the axial direction of the transport cylinder 21.
Therefore, the positional relationship between the tip of the intrusion prevention body 40 and the one end side connection port 28 is adjusted to suppress the discharge of the conveyance target T from the apparatus.
In addition, a transparent see-through window 47 is provided in predetermined portions of the transport cylinder 21, the exhaust cylinder 23, and the communication cylinder 26 including the deceleration transport cylinder portion 29.
Therefore, the movement state of the conveyance target T can be grasped by the see-through window 47, and the adjustment of the communication opening / closing valve 35 and the exhaust adjustment valve 36 can be performed more easily and accurately.

When the see-through window 47 is provided at least in the communication cylinder 26, the communication opening / closing valve 35 and the exhaust adjustment valve 36 for preventing the conveyance target T from being discharged out of the apparatus are easily adjusted.
Further, if the see-through window 47 is provided in the deceleration conveying cylinder portion 29, the communication opening / closing valve 35 and the exhaust adjustment valve 36 for adjusting the deceleration of the wind speed in the deceleration conveying cylinder portion 29 can be easily adjusted.
In addition, it is preferable to provide the see-through window 47 near the tip of the intrusion prevention body 40 because the position of the intrusion prevention body 40 can be easily adjusted.

If each of the transport cylinder 21, the exhaust cylinder 23, and the communication cylinder 26 including the transport cylinder 29 and the exhaust cylinder 31 is arranged in a horizontal state, the height of the entire transport device can be reduced, and It is preferable because the number of constraints can be reduced.

Further, since the communication cylinder 26 only needs to communicate the transport cylinder 21 on the upper side of the tank 20 and the exhaust cylinder 23 on the lower side of the tank 20, the shape of the communication cylinder 26 in the length direction is arbitrary. As shown in FIGS. 6 and 7, they may be arranged obliquely with respect to the transport cylinder 21 and the exhaust cylinder 23.

The guide rod 62 guides the transport target T separated by the transported object separation device 15 to the transport device 16 that transports the transport target T separately. The lower part of the discharge port 61 is made to face a predetermined position above the conveying device 16.
The discharge / feeding mechanism 50 is arranged vertically in the axial direction of the case 51 and the rotary blade 53, and the vertical height of the tank 20 and the discharge / feeding mechanism 50 is lowered. It is important that the restriction of the installation location is reduced by lowering the specific location, and the specific configuration of the case 51 and the rotary blade 53 is arbitrary, but the specific configuration of the discharge feeding mechanism 50 in this embodiment will be described.
It is preferable to provide 5 to 8 rotary blades 53 on the vertical rotary shaft 52 without deteriorating the confidentiality in the case 51.

Further, not only the distance between the upper edge of each rotor blade 53 and the lower surface of the top plate 55 of the case 51, but also the distance between the lower edge of each rotor blade 53 and the upper surface of the bottom plate 60 of the case 51 is determined. It is narrower than the size of, improving confidentiality.
The base of each rotary blade 53 is fixed to the vertical rotary shaft 52, the tip of each rotary blade 53 is fixed to the inner peripheral surface of the inner cylinder 64 whose upper and lower ends are open, and the inner circumference of the adjacent rotary blade 53 and inner cylinder 64 is fixed. The feeding chamber 65 formed by the surface is formed, the rotary blade 53 and the inner cylinder 64 are rotated together, and the conveyance target T that has entered the feeding chamber 65 from the supply port 56 is moved to the discharge port 61. To let it out.

Therefore, the conveyance target T in the feeding chamber 65 does not slide on the inner peripheral surface of the case 51 of the discharge feeding mechanism 50, and the conveyance target T in the feeding chamber 65 contacts the top surface of the bottom plate 60 of the case 51. It becomes only, and the damage of the conveyance target T is suppressed.
The discharge port 61 of the discharge / feeding mechanism 50 has a fan shape in plan view in accordance with the feeding chamber 65 and is opened larger than the feeding chamber 65 to ensure the discharge and dropping of the transport object T and prevent clogging.
In addition, the top plate 55 and the bottom plate 60 are detachably attached to the cylindrical case portion 66 of the case 51, and can be disassembled to facilitate maintenance.
Reference numeral 67 denotes an inspection window provided on the top board 55.

Further, in FIG. 8, the motor 70 for rotating the rotary blade 53 is disposed on the top plate 55 of the case 51. However, when the motor 70 is disposed on the lower surface of the bottom plate 60 of the case 51 as shown in FIG. 8, the connecting member 57 in FIG. 8 is omitted and the lower part of the tank 20 is connected to the supply port 56 of the case 51. Alternatively, the vertical length of the connecting member 57 can be shortened, and the height of the conveyed product separating device 15 can be reduced. It can be lowered, which is preferable.
70 </ b> A is a transmission unit that decelerates and transmits the rotation of the motor 70.
Accordingly, a dust cyclone 71 is provided on the exhaust cylinder 23 on the lower side in the blowing direction of the conveyed product separating apparatus 15. The dust cyclone 71 is a well-known one, and may be any device that separates and removes dust mixed in the conveying air (suction air), and details thereof are omitted. The exhaust cylinder 23 on the lower side of the dust cyclone is connected to the intake section 3 of the blower 2 via an air cleaner 72.

(Operation of the embodiment)
When the conveying object T is stuck on the sticking hopper 10 and then the air passage opening / closing valve (not shown) is closed and the blower 2 is energized, the air in the blower cylinder 1 is sucked by the blower 2 and this As a result, the inside of the tank 20 of the conveyed product separating apparatus 15 becomes negative pressure, and the object T to be conveyed in the tension hopper 10 is sucked into the blowing cylinder 1 and the conveying cylinder of the blowing cylinder 1 by the suction air flowing in the blowing cylinder 1. 21 to the tank 20 of the conveyed product separating apparatus 15.

  The conveyed product separation device 15 forms a tank 20 having an arbitrary shape with a relatively large capacity relative to the conveying cylinder 21 so as to attenuate the wind pressure / velocity that is the pressure applied to the object of the conveying wind blown from the conveying cylinder 21. Therefore, when the transport target T enters the tank 20, the transport wind is attenuated in the tank 20 more than when the transport target 21 blows, and the transport wind and the transport target T are separated. Then, the air T in the tank 20 is exhausted from the exhaust port 22, separated from the transport wind and released from the influence of the wind, the transport target T is discharged from the tank 20 through the supply port 56 of the discharge feeding mechanism 50. Fall in between.

In the discharge feeding mechanism 50, the conveyance target T that has dropped between the plurality of rotary blades 53 from the supply port 56 is moved onto the discharge port 61 by the rotary blades 53 that rotate in the vertical axis, and dropped from the discharge port 61. Supplied to the transport device 16 and transported to the next process.
The transported article separating device 15 connects and fixes the transport cylinder 21 of the blower cylinder 1 that forms the suction transport air passage 4 to the tank 20, and the exhaust cylinder of the blower cylinder 1 to the exhaust port 22 provided in the tank 20. 23 is connected, and the transport cylinder 21 in front of the tank 20 (on the upper side in the transport direction) is provided with a speed reduction unit 25 that slows the transport speed by the transport air, so the speed reduction unit 25 enters the tank 20. The transport speed of the transport target T in the foreground is slowed down, and the collision with the inner surface of the tank 20 is prevented from being damaged.

Since the speed reduction unit 25 connects the transport cylinder 21 and the exhaust cylinder 23 at a predetermined position in front of the tank 20 (upper side) with the communication cylinder 26, the connection between the communication cylinder 26 and the transport cylinder 21 is established. At this portion, the air path to the tank 20 and the air path to the exhaust cylinder 23 are branched, and the transfer speed of the transfer object T in the transfer cylinder 21 on the tank 20 side is decelerated from the communication cylinder 26. To do.
One end 27 of the communication cylinder 26 is connected to the conveyance cylinder 21 in front of the tank 20, and the part of the conveyance cylinder 21 between the one end side connection port 28 between the communication cylinder 26 and the conveyance cylinder 21 and the tank 20 is decelerated and conveyed. As the cylinder portion 29, the communication cylinder 26 allows the conveyance cylinder 21 to communicate with the exhaust cylinder 23 without the tank 20, so that the exhaust cylinder 23 sucks the inside of the conveyance cylinder 21 through the communication cylinder 26. Then, the communication tube 26 and the decelerating and conveying cylinder portion 29 are branched at the one end side connection port 28, and the conveying speed of the conveyance object T in the decelerating and conveying cylinder portion 29 can be reduced as compared with the conveying cylinder 21.

Further, since the communication cylinder 26 communicates the transport cylinder 21 at a predetermined position in front of the tank 20 (upper side) and the exhaust cylinder 23, the connecting portion with the communication cylinder 26 is connected to the exhaust cylinder 23 side. Therefore, the transport speed of the transport target T in the transport cylinder 21 on the tank 20 side can be reduced.
Since the communication cylinder 26 on the upper side of the connection port 30 is provided with the communication opening / closing valve 35, the air pressure / velocity in the communication cylinder 26 can be adjusted by the communication opening / closing valve 35, and the conveyance object T is communicated. This prevents accidental suction by the common cylinder 26 and discharge to the outside of the machine.
For example, when the conveyance object T enters the communication cylinder 26 from the one end side connection port 28, the communication opening / closing valve 35 is tightened to reduce the wind speed in the communication cylinder 26, and the conveyance object T is discharged outside the apparatus. To prevent.

Since the exhaust adjustment valve 36 is provided at a predetermined position of the exhaust cylinder portion 31 on the upper side of the connection port 30, the suction pressure is adjusted from the exhaust cylinder 23 to the communication cylinder 26 by the exhaust adjustment valve 36. The speed reduction efficiency of the conveyance speed of the conveyance target T in the deceleration conveyance cylinder part 29 can be improved.
That is, the communication open / close valve 35 can reduce the wind speed in the communication cylinder 26, but cannot increase the wind speed. Therefore, even if the communication open / close valve 35 is fully opened, When the wind speed is not sufficiently slowed down, the exhaust speed adjustment valve 36 is throttled to increase the wind speed in the communication cylinder 26, thereby decelerating the wind speed in the deceleration transport cylinder portion 29.

Since an intrusion prevention body 40 for preventing the conveyance target T from entering the communication cylinder 26 is provided in the conveyance cylinder 21 on the upper side of the one end side connection port 28, the conveyance target T is connected to the communication cylinder 26. This prevents the exhaust tube 23 from flowing in the direction and being discharged outside the machine.
The intrusion prevention body 40 has an arc portion 41 that is aligned with the inner surface of the conveyance cylinder 21, and the opposite surface of the arc portion 41 is close to the inner surface of the conveyance cylinder 21 on the opposite side of the one end side connection port 28. Since it forms in the inclined surface 42 inclined in the direction away from the one end side connection port 28 as it approaches, the conveyance target T in the conveyance cylinder 21 leaves | separates from the one end side connection port 28 by the inclined surface 42 of the intrusion prevention body 40. It is guided in the direction, passes through the one end side connection port 28, enters the decelerating conveyance cylinder portion 29, and is conveyed to the tank 20.

Since the intrusion prevention body 40 is attached so that the mounting shaft 43 is inserted into the long hole 44 and is movable in the axial direction of the transport cylinder 21, the positional relationship between the tip of the intrusion prevention body 40 and the one end side connection port 28 is adjusted. Thus, the conveyance target T is prevented from being discharged out of the apparatus.
In addition, since transparent see-through windows 47 are provided in predetermined portions of the transport cylinder 21, the exhaust cylinder 23, and the communication cylinder 26 including the deceleration transport cylinder portion 29, the transport object T is moved by each see-through window 47. By grasping the state, the communication opening / closing valve 35 and the exhaust adjustment valve 36 can be adjusted.
If the conveyance cylinder 21, the exhaust cylinder 23, and the communication cylinder 26 are arranged in a substantially horizontal state, the height of the entire conveyance apparatus can be reduced, and restrictions on the installation location can be reduced.

  Further, since the communication cylinder 26 only needs to communicate the transport cylinder 21 on the upper side of the tank 20 and the exhaust cylinder 23 on the lower side of the tank 20, the shape of the communication cylinder 26 in the length direction is arbitrary. 6 and FIG. 7, when the slant is arranged with respect to the transport cylinder 21 and the exhaust cylinder 23, the distance between the transport cylinder 21 and the exhaust cylinder 23 is reduced, and the length of the communication cylinder 26 is increased. It is possible to secure the length to a predetermined length, and it is possible to install the communication opening / closing valve 35 easily.

Since a plurality of rotor blades 53 projecting radially from the longitudinal rotating shaft 52 are provided at predetermined intervals in the rotational direction of the longitudinal rotating shaft 52, the discharge feeding mechanism 50 provided with the rotor shaft 53 rotating in the horizontal axis is provided. Compared to this, the vertical height can be lowered.
Since the case 51 has a supply port 56 formed at a predetermined position above the top plate 55 and a discharge port 61 is formed in the bottom plate 60 of the case 51, the transport object T in the tank 20 is adjacent to the supply port 56. The conveyance object T that has fallen into the feeding chamber 65 between the rotary blades 53 and dropped between the plurality of rotary blades 53 is moved on the bottom plate 60 to the discharge port 61 by the rotary blades 53 rotating in the vertical axis. Then, it falls from the discharge port 61 and is supplied to the transport device 16 to be transported to the next process.

Since 5 to 8 rotary blades 53 are provided on the vertical rotary shaft 52, a distance (space volume) between the supply port 56 and the discharge port 61 can be secured, and without reducing the confidentiality of each delivery chamber 65, The conveyance target T can be paid out.

Since the feeding chamber 65 formed by the surface is formed and the rotary blade 53 and the inner cylinder 64 are rotated together and moved, the transfer object T in the feeding chamber 65 is contained in the case 51 of the discharge feeding mechanism 50. Only the upper surface of the bottom plate 60 of the case 51 is in sliding contact with the conveyance target T in the feeding chamber 65 without sliding against the peripheral surface, and damage to the conveyance target T is suppressed.

In FIG. 8, the motor 70 for rotating the rotor blades 53 is disposed on the top plate 55 of the case 51. However, the motor 70 is disposed on the lower surface of the bottom plate 60 of the case 51 as shown in FIG. Therefore, the connection member 57 in FIG. 8 is omitted and the lower part of the tank 20 is connected to the supply port 56 of the case 51, or the vertical length of the connection member 57 can be shortened. The height can be lowered.
Accordingly, the exhaust cylinder 23 on the lower side in the blowing direction of the conveyed product separating device 15 is provided with the dust cyclone 71, so that dust mixed in the transport air (suction air) is separated and removed by the dust cyclone 71. Further, the air is sucked into the air intake portion 3 of the blower 2 through the air cleaner 72 to prevent the blower 2 from being damaged.

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 intrusion prevention body 40 varies depending on the axial direction of the communication cylinder 26, and the arc portion 41 is not necessarily formed on the upper surface of the intrusion prevention body 40 and may be formed on the side surface.
