A valve rod 34 for vertically moving a valve body 33 joined to an inner peripheral surface of a filling port 32 opened at a lower end of the device body 31 via an annular seal member 35 by an air cylinder (not shown) or the like.
It is provided at the lower end of. The valve element 33 is formed in a dish shape with the lower end opened, and is attached to the lower end of the valve rod 34 by an upward bolt 36 penetrating the central portion thereof. Incidentally, reference numeral 37 in the figure is an inlet of the liquid material.

た。[Problems to be Solved by the Invention] In the above-described filling device B, the opening portion (recess) 33a of the valve body 33 is shallow, and the tapered surface 33b forming the inner peripheral surface of the opening portion 33a.
The inclination angle α of is gentle (about 45 °)
A head portion 36a of 36 projects into the opening 33a. For this reason,
For example, when continuously filling a container with a high-viscosity liquid sealant by a fixed amount, when the valve body 33 is lowered to close the filling port 32, the sealing agent remaining on the inner peripheral surface of the filling port 32 is Disc
As it adheres to the vicinity of the lower end of 33 and the opening / closing operation of the valve element 33 is repeated, the adhered sealing agent gradually accumulates in the opening 33a (the inner peripheral surface 33b and the periphery of the head 36a of the bolt 36). . On the other hand, the container arranged below the filling port 32 is usually placed on a conveying device such as a belt conveyor or a rotary table, and when the sealing agent is filled, the container is conveyed from below the filling port 32 to another place. After that, the empty container is conveyed below the filling port 32. Then, the sealing agent accumulated in the opening 33a of the valve body 33 suddenly drops from the opening 33a of the valve body 33 when it grows to a certain size (amount). May fall and stain the periphery of the opening of a can-made container or the like, or may drop onto the open sealing surface of a paper-made container or the like to cause a sealing failure.

Liquids cannot adhere. In addition, even in the case of a highly viscous liquid, almost no liquid adheres to the valve body, but even if it adheres, the amount is extremely small, and the inclination of the lower end of the inner peripheral surface is steep and the valve body Since the opening has a large depth, the liquid material does not further adhere to the adhered liquid material to grow (agglomerate). Therefore, the liquid material does not unexpectedly drop while the container is being carried out below the filling port.

作業開始用のスイッチである。The filling device A is used, for example, as shown in FIG. 3, to fill a small amount of the liquid material L stored in a large storage tank 21 into a small container S by a predetermined amount. In this case, the storage tank
An outlet 21a provided at the bottom of 21 is connected to a suction port 22a of a positive displacement pump, for example, a uniaxial eccentric pump 22 via a supply pipe 23, and a discharge port 22b of the pump 22 is a separate supply pipe 2
It is connected via 4 to the inlet 17 of the filling device A. Also,
One end of the circulation pipe 25 is connected to the outlet 16 of the filling device A, and the other end is inserted into the storage tank 21. Further, at the air port 10a of the air cylinder 10 on the filling device A, the solenoid valve 28
One end of a hose 27 which is interposed is connected, and the other end of the hose 27 is connected to a compressed air source 26. Solenoid valve 28 is a control device
The electromagnetic valve 28 is connected to the control device 29, and the electromagnetic valve 28 is closed by a command from the control device 29. In the illustrated example, the rotation speed of the pump 22 is detected by the controller 29,
When the predetermined number of revolutions is reached, the solenoid valve 28 is closed. In addition,
Instead of detecting the rotation speed of the pump 22, a timer may control the opening time of the solenoid valve 28. Reference numeral 30 in the figure is a switch for starting the filling operation.
前記一軸偏心ポンプ22は常時一定の速度で回転してお
り、常態(弁体4の閉鎖状態)では、貯留タンク21内の
液状物Lは充填装置A内を通過して貯留タンク21内に循
環される。The uniaxial eccentric pump 22 always rotates at a constant speed, and in the normal state (closed state of the valve body 4), the liquid material L in the storage tank 21 passes through the filling device A and circulates in the storage tank 21. To be done.
小型の容器Sに一定量ずつ液状物Lを連続的に充填する

れにより、ポンプ22の吐出口22bから搬送されてきた液
状物Lが容器S内に充填される。なお、充填中には、液
状物Lは充填装置Aから貯留タンク21へ循環されない。When a small amount of the container S is continuously filled with the liquid L by a fixed amount, when the container S is sequentially conveyed below the filling port 2 and stopped, the solenoid valve 28 is opened via the control device 29. As a result, in the air cylinder 11, the valve body 4 rises together with the valve rod 3 against the spring 12, the filling port 2 is opened, and the flow port (valve seat) 18 in the apparatus body 1 is closed. As a result, the liquid material L conveyed from the discharge port 22b of the pump 22 is filled in the container S. The liquid material L is not circulated from the filling device A to the storage tank 21 during filling.
そして、ポンプ22が所定回数回転した後(あるいは、一

充填装置A内を通過して貯留タンク21に循環される。こ
のあとすぐに、液状物Lが充填された容器Sが搬送さ
れ、空の容器Sが充填口2の下方に送られてくる。Then, when the electromagnetic valve 28 is closed via the control device 29 after the pump 22 has rotated a predetermined number of times (or after a certain period of time has elapsed), the supply of compressed air to the air cylinder 10 is cut off, and the valve body is closed. 4 is lowered together with the valve rod 3 by the urging force of the spring 12, the filling port 2 is closed, and at the same time, the flow port 18 in the apparatus main body 1 is opened. As a result, the filling of the liquid material L into the container S is stopped, and the liquid material L in the storage tank 21 passes through the filling device A again and is circulated to the storage tank 21. Immediately after this, the container S filled with the liquid material L is conveyed, and the empty container S is sent below the filling port 2.
上記のような作業が繰り返されることにより、一定量の
液状物Lが容器Sに連続して充填される。By repeating the above-described operation, the container S is continuously filled with a fixed amount of the liquid material L.
ところで、弁体4の閉鎖時あるいは開放時に、充填口2
内の液状物Lが弁体4の下端に付着しようとするが、上

容器Sの搬送中に液状物Lが落下することがなく、容器
Sの開口部周縁や容器Sの周辺を液状物Lで汚すことが
ない。By the way, when the valve body 4 is closed or opened, the filling port 2
The liquid material L therein tends to adhere to the lower end of the valve body 4, but as described in the section of the above action, the liquid material L does not usually adhere. Therefore, the liquid material L does not drop during the transportation of the container S below the filling port 2, and the periphery of the opening of the container S and the periphery of the container S are not contaminated with the liquid material L.

る。FIG. 4 shows a main part of a filling device according to another embodiment of the present invention. The main difference between the filling apparatus A'of the present embodiment and the above-mentioned embodiment is that the apparatus main body 1 does not have the carry-out port 16 (FIG. 1) for the liquid material L, and therefore the liquid body is closed when the filling port 2 is closed. This is the point where the object L does not circulate. Therefore, neither the valve seat 18 nor the annular valve body 19 is provided. However, since it is basically the same as the filling device A of the above-mentioned embodiment, the members common to the above-mentioned embodiment are indicated by the reference numerals used in FIG. 1, and the description thereof will be omitted.
[考案の効果] 以上説明したことから明らかなように、この考案の充填

付着し易い高粘性や高濃度の液状物の充填に、好適であ
る。Since the depth of the opening in the valve body is deep and the inner peripheral surface of the opening is formed into a steeply tapered surface, liquid matter does not easily adhere to the valve body, and even if it adheres, liquid matter Since the liquid substance does not grow due to the adherence of the liquid substance, the liquid substance does not accumulate on the valve body as in the conventional case, and so-called unintended liquid sagging does not occur. Therefore, unlike the conventional filling device, when the liquid material is continuously filled in a large number of containers, the liquid material does not drop around the opening seal part of the container or around the container, and the opening seal part is sealed. It does not cause defects or require cleaning of liquids that fall around the container. In particular, it is suitable for filling a high-viscosity or high-concentration liquid substance that easily adheres to the valve body.
