Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention discloses that when a pump for pumping a viscous material such as liquid silicone rubber from a material container is used, it is housed in an inductor plate and The present invention relates to a residual material removing device for an inductor plate that does not allow a material to remain on the bottom.

[Conventional technology]

As a device for pumping the viscous material, there is a device for driving a plunger pump, and an inductor plate 1 is attached to a suction port of the pump as shown in FIG. The inductor plate 1 is covered with the material of the material container 2, and an annular wiper 3 attached to the outer peripheral end of the inductor plate 1 is in contact with the inner wall surface of the material container 2. A piston 4 connected to the plunger is arranged at approximately the center of the inductor plate 1, and this is moved up and down by an actuator so that the viscous material in the material container 2 is drawn to the suction port of the pump. It is fed to a predetermined device.

Then, when the material in the material container 2 decreases, the inductor plate 1 also gradually descends together with the material.

[Problems to be solved by the device]

However, as shown in FIG. 4, the above-described inductor plate 1 is inclined from the central portion where the piston 4 is located to the outer peripheral end portion where the wiper 3 is attached, and has a shape close to a conical shape. Are doing
Therefore, when the inductor plate 1 descends to the bottom of the material container 2, a large space 5 is formed between the bottom plate 2a of the material container 2 and the inductor plate 1 as shown in FIG. A part of the material in the space 5 is fed by driving the pump, but the whole material cannot be fed, and the material remains.

The material remaining at the bottom of the material container 2 cannot be used, and is therefore discarded and wasted. Moreover, the larger the material container 2 becomes, the larger the amount of remaining material becomes. In addition, in order to dispose, it is processed as industrial waste, and this processing work is troublesome and troublesome.

Therefore, the purpose of this invention is to reduce the amount of material that remains in the material container when feeding viscous material with a plunger pump that uses an inductor plate, to eliminate waste of material and to dispose of it. An object of the present invention is to provide a residual material removing device for an inductor plate that requires the least effort.

[Means for solving the problem]

For the above purpose, the residual material removing device according to the present invention is
In an inductor plate that is attached to the suction port of a material pressure-feeding plunger pump and covers the material in the material container to shield the material from the outside air, the inductor plate is accommodated in the inductor plate, and the side surface is part of the inner surface of the inductor plate. The bottom surface of the material container is formed in parallel with the bottom plate of the material container or an appropriate conical surface, and a suction hole through which the plunger of the plunger pump is inserted is formed in the center of the inductor plate. The outer shape of the portion facing the air vent hole is made smaller than the inner diameter of the portion of the inductor plate including the air vent hole to form a space portion between the inductor plate and the inner side surface, and the space portion communicates with the bottom side. It is characterized by doing.

[Action]

When the inductor plate descends until it comes into contact with the bottom plate of the material container, the space between the inductor plate and the bottom plate contains the residual material removing device, and therefore remains in the space. The material to try is
It is pushed away by this residual material removal tool. Therefore, the material does not remain in the space.

〔Example〕

Hereinafter, the residual material removing device according to the present invention will be specifically described with reference to the embodiment shown in FIGS. 1 to 3.

FIG. 2 is a perspective view showing a state in which the plunger pump 10 for pressure-feeding the material is lowered and is positioned on the bottom plate 11a of the material container 11. The inductor plate 12 is provided at the tip of the suction port 10a of the plunger pump 10. Is attached, and the inside of the inductor plate 12 communicates with the suction port 10a of the plunger pump 10. A piston 13 is connected to a tip end portion of a plunger 10b of the plunger pump 10, and the piston 13 is arranged at a substantially central portion of the inductor plate 12.

As shown in FIGS. 2 and 3, the inductor plate 12 has a second truncated cone portion 12b which is continuous with the lower end portion of the first truncated cone portion 12a which is continuous with the suction port 10a. Stand 1
The end of 2b is bent upward to form a substantially L-shape. An annular wiper 14 made of rubber or the like inside the L-shape is housed. When the inductor plate 12 is placed in the material container 11, the wiper 14
Contacts the inner wall surface of the material container 11. Further, an air vent hole 12c is formed at an appropriate position in the vicinity of the joint between the first truncated cone part 12a and the second truncated cone part 12b of the inductor plate 12, and the air vent hole 12c is formed by the air valve 15. It can be opened and closed.

Then, inside the inductor plate 12, a residual material removing device 20 having an outer shape matching a part of the inner surface of the inductor plate 12 is accommodated in a state of being locked by an appropriate locking means. That is, the residual material removing device 20 is appropriately attached to the lower end portion of the first truncated cone portion 21 having a shape substantially matching the inner side surface of the first truncated cone portion 12a of the inductor plate 12 than the outer diameter of the lower end portion. A neck portion 22 having a reduced diameter is continuously formed, and a second truncated cone portion 23 having a shape substantially conforming to the inner surface of the second truncated cone portion 12b of the inductor plate 12 is continuously formed at the lower end portion of the neck portion 22. ing. Therefore, the third
As shown in the figure, in a state where the residual material removing device 20 is accommodated in the inductor plate 12, the bottom surface of the first truncated cone portion 21, the outer peripheral surface of the neck portion 22, and the second portion are formed in the portion where the neck portion 22 is formed. A space 17 is formed by the upper surface of the truncated cone portion 23 and the inner side surface of the inductor plate 12. A suction hole 24 penetrating the first truncated cone portion 21, the neck portion 22, and the second truncated cone portion 23.
Is formed, and the inner diameter of the suction hole 24 is made to substantially coincide with the inner diameter of the suction port 10a of the plunger pump 10, so that the piston 13 can move in the suction hole 24. As shown in FIG. 3, the bottom surface of the second truncated cone portion 23 is formed into an appropriate conical surface 25. Further, an appropriate number of air holes 26 are formed so as to penetrate from the upper surface of the second truncated cone portion 23 to the conical surface 25, and the upper surface side of the second truncated cone portion 23 and the conical surface 25 side communicate with each other. Further, by locating the air vent hole 12c so as to face the neck portion 22, the air vent hole 12c communicates with the air hole 26 through the space portion 17, and further to the conical surface 25 side of the base 2 truncated cone portion 23. It is in communication. Further, the residual material removing device 20 is formed of aluminum, synthetic resin, or the like.

The plunger pump 10 is driven by an actuator (not shown), and the plunger 10b moves up and down to suck up the viscous material in the material container 11 and discharge the viscous material from the discharge port 10c to supply it to a predetermined device.

The operation of the residual material removing device 20 configured as described above will be described below.

After covering the material in the material container 11 with the inductor plate 12, the air valve 15 is opened to appropriately discharge the residual air below the inductor plate 12, and then the air valve 15 is closed. That is, when the air valve 15 is opened, the part sandwiched between the surface of the material and the conical surface 25 of the second truncated cone part 23 and the space part 17 are in communication with the atmosphere, so that the residual air in these parts remains in the air valve. Emitted from 15 into the atmosphere. When the air valve 15 is closed, these parts are cut off from the atmosphere. Next, when the plunger pump 10 is driven, the plunger 10b moves up and down and the piston 13 moves up and down. The piston 13 moves up and down so that the suction hole 24 of the residual material removing device 20 housed in the inductor plate 12
By moving up and down inside, the viscous material in the material container 11
Attract to. At this time, since the material flows along the conical surface 25, the material is smoothly drawn to the suction hole 24.
Then, the material drawn to the suction hole 24 is sucked into the suction port 10a.
Pumped into the plunger pump 10 from the discharge port 10
It is fed from c to the specified device.

When the material in the material container 11 is fed and the capacity is reduced, the inductor plate 12 is gradually lowered together with the plunger pump 10, and when the inductor plate 12 is lowered to the lowermost position, as shown in FIG. The bottom plate 11a is reached.
In this state, as shown in FIG. 3, since a slight gap is formed between the bottom plate 11a and the conical surface 25 of the residual material removing device 20, the material remains at the bottom of the material container 11. Almost never. Therefore, the material in the material container 11 can be fully utilized.

In this embodiment, the outer shape of the residual material removing device 20 is shown as a shape in which the first truncated cone portion 21, the neck portion 22 and the second truncated cone portion 23 are combined.
Any shape may be used as long as it matches the shape of the inner surface.

Further, although the bottom surface shape of the residual material removing device 20 is shown as the conical surface 25, if the smoothness of the flow of the material is not impaired, the residual material removing tool 20 should be formed in a shape corresponding to the shape of the bottom plate 11a. However, if formed in parallel with the shape of the bottom plate 11a, no gap is formed between the bottom plate 11a and the residual material removing device 20, so that the material in the material container 11 can be used almost completely.

Further, in this embodiment, the residual material removing device 20 is stored in advance inside the inductor plate 12, but the residual material removing device 20 is previously stored in the material container.
It can also be used by sinking into 11.

[Effect of device]

As described above, according to the residual material removing device of the present invention, when the remaining amount of the material is small and the inductor plate is lowered to the bottom of the material container, the gap between the bottom plate of the material container and the inductor plate is generated. Since the residual material removing device exists, the material hardly remains in the gap. Therefore, the material contained in the material container can be fully utilized without being left, and the material can be saved.

Further, since the amount of the material remaining in the material container can be reduced as much as possible, the disposal of the residual material does not take time. In particular, in the case of a large-sized material container, it is advantageous for handling the container after use that the disposal of the contents does not take time.

Furthermore, since it is formed in a shape that matches the inductor plate, it can be easily formed according to an arbitrary inductor plate with a simple structure, and can be provided at a low cost.
