When closing 2, the bottom plate of the annular transport pipe 4 is formed. A pin holding member 17 holding a pin 17a is attached to a tip end portion of a piston rod of the air cylinder 18, and the pin 17a is inserted into an elongated hole 16a provided in a crank 16 fixed to a rotating shaft 15. . Therefore, the air cylinder 18 is activated and the pin 17
a is pushed out and the crank 16 is moved from the position of the broken line to the position of the alternate long and short dash line, whereby the rotary shaft 15 is rotated,
The gate plate 13 is rotated from the solid line position to the alternate long and short dash line position to close the branch pipe 12. When the branch pipe 12 is opened and the annular transport pipe 4 is closed, the pin holding member 17 of the air cylinder 18 is pulled back. That is, as the pin holding member 17 reciprocates in the direction indicated by the arrow a, the gate plate 13 is rotated within the range indicated by the arrow b.

When the gate plate 13 is in a position to close the annular transportation pipe 4, the coffee beans Bm are fed from the annular transportation pipe 4 into the silo compartment 8 via the branch pipe 12. At this time, the coffee beans Bm are introduced. Some of B may collide with the gate plate 13 and may be broken by the impact at the time of collision. Therefore,
The gate plate 13 of the first embodiment is installed so that the incident angle θ of the coffee beans B with respect to the gate plate 13 is large so as to mitigate the impact of the coffee beans B, and therefore the upstream end of the gate plate 13 is arranged. To the downstream end, that is, the length from the upstream end to the downstream end of the opening of the branch pipe 12 is set to be relatively large. The incident angle θ is preferably 45 degrees or more. This can also be applied to the distribution of coffee roasted beans that are susceptible to breakage.

Further, the shielding plate 14 for shielding the rotating shaft 15 on the lower surface side of the gate plate 13 is formed into a gentle curved surface which is convex toward the gate plate 13 side, and the upper surface of the upstream end thereof is formed on the upper surface of the gate plate 13. The upper surface of the downstream end portion is fixed to the rotating shaft 15 on the lower surface. Further, an inclined end face 14a is formed by dropping the corner of the upstream end of the shield plate 14. The curved plate is used as the shield plate 14 of the rotating shaft 15 and the inclined end surface 14a is formed at the tip end of the shield plate 14 in order to reduce the impact of the coffee beans B.

Further, referring to FIG. 3, in order to prevent air from leaking into the branch pipe 12 when the gate plate 13 closes the branch pipe 12, the front end of the gate plate 13 is opposed to the annular transport pipe 4. A receiving plate 19 is provided so as to be fixed to the bottom plate of the above, and prevents the reduction of the wind force in the annular transport pipe 4.

The other branch pipes 12 ₂ , 12 ₃ ...
.., 12 ₁₂ and similar dampers 11 ₂ , 11 ₃ , ...
..., 11 ₁₂ is attached, and a damper integrated with any branch pipe corresponding to the type and grade of coffee beans B supplied by pneumatic transportation, for example, the damper 11 of the branch pipe 12 ₃ . _By actuating ₃ to close the annular transport pipe 4, the coffee beans B are distributed and stored in the compartment 8 _{3 of the} silo 8 via the branch pipe 12 ₃ .

Returning to FIG. 1, each section 8 ₁ , 8 of the silo 8 is
_2, 8 _3, ..., chute 22 having a built-in each of the lower opening and closing control board 8 _{12 1,} 22 _2, 22 _3, ...
..., 22 ₁₂ is attached. Further, a weighing hopper 23 fixed to the frame 26 is installed immediately below them, and a blender 24 is installed further below the weighing hopper 23. These configurations and operations are exactly the same as those of the first conventional example. Therefore, the description is omitted.

As described above, the distribution of the coffee beans B is carried out immediately above the silo 8 on the annular transport pipe 4 and the branch pipes 12 ₁ , 12 ₂ , 12 ₃ , ...
..., 12 _12, integral damper 11 ₁ to each of these, 11 _2, 11 _3, ..., because depending on the 11 _12, dispensing device constituted by these is the height 1m about Yes, it is extremely compact compared to the distributor of the first conventional example. As a result, the capacity of the silo 8 of the first embodiment is about 50 as compared with the silo 108 of the first conventional example, with the total height of the machining apparatus 10 of the first embodiment and the machining feed 100 of the first conventional example being the same. % Will be increased.

(Second Prior Art) FIG. 5 is a plan view of the coffee bean processing apparatus 20 of the second embodiment and corresponds to FIG. 3 of the first embodiment. Further, FIG. 6 shows an annular transport pipe 4'and a damper 1 which constitute a distributor used in the processing apparatus 20.

In FIG. 5, the coffee bean supply pipe 1'is connected to the annular transport pipe 4'without branching,
Branch pipes 12 ₁ ′, 12 ₂ ′, 12 are provided in the annular transport pipe 4 ′.
₃ ', ..., 12 ₁₂ ' are each damper 11
It is installed with ₁ ', 11 ₂ ', 11 ₃ ', ..., 11 ₁₂ '. Since other than that is the same as the case of the first embodiment, the same reference numerals are given to the respective components and the description thereof will be omitted, and the points different from the first embodiment will be described below.

As described above, the coffee bean supply pipe 1'is connected to the annular transport pipe 4'without branching, and the coffee bean is pneumatically transported in the direction shown by the arrow. Depending on the type and grade of coffee beans, it may go around the annular transport pipe 4'approximately once, but since the branch valve 2 and its switching control system in the first embodiment are not required, the cost is reduced accordingly.

FIG. 6 is a sectional view taken along the line [6]-[6] in FIG. 5, showing an annular transport pipe 4 ', a damper 11',
The branch pipe 12 'is basically configured in substantially the same manner as the annular transport pipe 4, the damper 11, and the branch pipe 12 in the first embodiment. In addition, in FIG. 6, the subscripts are omitted and the frame 26 is omitted. The gate plate 13 'of the damper 11' is formed so as to form a part of the bottom plate of the rectangular annular transport pipe 4'when the branch pipe 12 'is closed. The gate plate 1 of the first embodiment has a length from the upstream end to the downstream end in the transport direction of
The length is shorter than that of No. 3 and therefore the length from the upstream end to the downstream end of the opening of the branch pipe 12 'is also short. The gate plate 13 'has the lower surface of the downstream side edge portion fixed to the rotating shaft 15,
The pin 17a 'of the pin holding member 17' attached to the tip of the piston rod of the air cylinder 18 'is fixed to the rotating shaft 15', and the slot 16 of the crank 16 'is fixed.

That is, as the pin holding member 17 reciprocates as shown by the arrow a ', the gate plate 13 rotates between the position for closing the branch pipe 12' and the position for closing the annular transport pipe 4'as shown by the arrow b '. To be done.

As described above, since the length from the upstream end to the downstream end of the gate plate 13 'is short, the gate plate 13' of coffee beans B is located at the position where the gate plate 13 'closes the annular transport pipe 4'. The incident angle θ ′ with respect to is smaller than the incident angle θ in the first embodiment. Therefore coffee beans B is the gate board 1
The impact received when colliding with the 3'is so great.
Further, a flat plate is used for the shield plate 14 'that shields the rotating shaft 15', and the corner of the tip of the shield plate 14 'is not dropped. The impact of the coffee beans B upon colliding with the flat shield plate 14 'is further increased. Therefore, it can be applied to the distribution of green beans of coffee which are not easily broken. Further, there is air leakage because the gate plate 13 'creates a gap between the tip of the gate plate 13' and the bottom plate of the annular transport pipe 4'facing it when the branch pipe 12 'is closed. As described above, the annular transport pipe 4 ′ and the damper 1 in the processing apparatus 20 of the second embodiment.
