面と密に接してシールできるように図られている。Conventionally, a branching device has been one in which a plate-shaped branching valve 2 as shown in FIG. 1 is rotated within an air slide to switch the direction of powder flow. As shown in the figure, the air slide 1 has a conduit held in the center by an air-permeable material, often a cloth 21, held on both sides by holding plates 22 smaller than the cloth.
This is configured so that it can be rotated around a shaft 23, so that the portion of the fabric protruding from the periphery of the clamping plate 22 is in close contact with the inner circumferential surface of the upper powder transfer conduit at the top of the air slide 1. It is designed so that it can be sealed.

以下、第２図に示す本発明の一実施例について説明する
。An embodiment of the present invention shown in FIG. 2 will be described below.
なお図中、第１図の従来装置と共通部分については、同

に移行している。Reference numeral 1 denotes an air slide, in which an inclined conduit is divided into upper and lower conduits by a cloth 3 stretched as an air-permeable partition plate approximately in the center. Powder to be transferred is supplied to the upper pipe line 11 from the left side, and compressed air is sent to the upper pipe line 12. The entire air slide is tilted slightly downward to the right, and the air passes through the fabric 3 into the upper pipe 1.
2, the powder is suspended, and the powder is moving to the right with extremely low resistance.

。The bottom of the upper conduit is open, and a branch pipe 4 is attached to the opening. A guide portion 5 is formed between the opening and the fabric 3 for slidingly and rotationally guiding the lower branch valve body. This guide portion 5 has an inner surface 54 forming an arc so as to be in contact with the semi-cylindrical outer circumferential surface of the downstream branch valve body 6. The cloth 3 is fixed to the side end portion of the guide portion 5 close to the cloth 3.

管路内部の空気が漏出しないようにシール７３．７４，
７５．７６によって密封されている。As shown in detail in FIG. 3, the branch valve body 6 has disk-shaped wall plates 62 attached to both ends of a semi-cylindrical body 61, and an air-permeable plane between the two wall plates 62, 62''. Cloth 65 as a side plate is stretched to form a semi-cylindrical closed chamber 68. Shafts 63 and 63'' are connected to the wall plates 62 and 62'', respectively, and one axis 63 is connected to the pipe. It is rotatably supported by a support plate 71 fixed to the side wall, and the other shaft 63'
is connected to a shaft 81 of a rotary air cylinder that is driven to rotate reciprocatingly by a key or the like. The shaft 63 is provided with a screw hole 66 for connecting a compressed air supply pipe (not shown),
From there, an air supply hole 64 extends into the interior of the branch valve body 6 (see FIG. 3). The rotating parts of both wall plates 62 and 62' are sealed with seals 73 and 74 to prevent the air inside the pipe from leaking.
Sealed by 75.76.

ある。そのために、それぞれの位置で分岐弁体６と掛止
するストッパー５１．５２が設けられている。The branch valve body 6 is capable of reciprocating rotation around its axis 62, 62', but the range is such that the surface of the fabric 65 is at the position of the surface of the fabric 3 of the air slide 1, as shown in FIG. Between the position of the two-dot chain line in the same figure, that is, the cloth 6
5 opens the upper pipe line 11 and closes the branch pipe 4;
This is between the position where the earthen pipe line 11 is closed and the branch pipe 4 is opened. For this purpose, stoppers 51, 52 are provided which engage the branch valve body 6 in the respective positions.
次に本実施例装置によってどのように粉体の流れが分岐
管に切り替わるかを説明する。Next, how the flow of powder is switched to the branch pipe by the apparatus of this embodiment will be explained.
先ず当初分岐弁体６の布地６５の面は水平状態ににあり

体６の内部から布地６５を通して空気が吹上げているの
で粉体は、分岐弁６の上を通過する際にも引続き浮遊状
態にあり上記粉体は滑らかに下流に向けて移送される。First, it is assumed that the surface of the fabric 65 of the branch valve body 6 is initially in a horizontal state, and the flow of powder is linear from the left to the right as shown in FIG. At this time, the surface of the fabric 65 of the branch valve body 6 is completely aligned with the surface of the fabric 3 of the air slide 1, so there is no resistance to the flow, and the fabric 65 is passed from the inside of the branch valve body 6. Since the air is blown up, the powder remains in a suspended state even when passing over the branch valve 6, and the powder is smoothly transferred downstream.

トルを分岐管４の方向に変向する。Next, when the flow of the powder is caused to flow into the branch pipe 4, the air cylinder 8 is operated. Then air cylinder 8
The branch valve 6 is connected to the shaft 81 of the branch valve 6 by the shaft 63'.
rotates as shown by the two-dot chain line in FIG. 2(1) and stops at the stopper 52. In this state, the earthen pipe 11 is completely closed and the branch pipe 4 is opened. Therefore, the powder flowing from the left side is diverted to the branch pipe 4. At this time, compressed air is still being fed into the closed chamber 68 of the branch pipe 4 through the air supply port 64.
Air is blown out from the fabric 65, and the powder does not adhere to the fabric 65 during the curved flow, and moreover, its vector is easily diverted in the direction of the branch pipe 4.

ができ、ひいては製品の性能の向上に貢献する。As described above, according to the air slide branching device of the present invention, (1) Regardless of whether the flow of powder in the air slide is in the above-mentioned direct current state or curved flow state, the guide chamber 5 and the branch valve body 6 can Since the seal between the two is reliable, there is no leakage between the two, and air is blown out from the branch valve at bends, so there is no adhesion or accumulation of powder, and as a result, powder transfer is prevented. The amount can be measured with extreme precision, which in turn contributes to improved product performance.
