Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is used for a high-viscosity pump for supplying a high-viscosity material such as grease, putty, sealing material, adhesive, and printing ink by pressure. It relates to a high viscosity material container.

(Prior Art) JP-B-58-23985 and JP-B-63-10
Japanese Unexamined Patent Publication No. 16 discloses a high-viscosity pump suitable for pressure-feeding high-viscosity materials such as grease, putty, sealing materials, adhesives, and printing inks.

As shown in FIG. 6, the basic structure of this high-viscosity pump is such that when the pump body 12 is press-fitted into the container 13 by the elevating mechanism 11 such as a fluid pressure cylinder erected on the base 10, The high-viscosity material in the container 13 is collected in the lower end opening of the pump body 12 by the inductor plate 14 provided in the lower part, and is further reciprocated by the pump drive section 15 provided in the upper part of the pump body 12. The high-viscosity material is sucked up by the inner pump mechanism and discharged from the high-viscosity material discharging section 16.

As shown in FIG. 7, the inductor plate 14
Is a plate in which a rubber plate 14b placed on the outer periphery of the plate body 14a is sandwiched between pressing plates 14c and fixed by bolts 14d. As shown in FIG. 8, the inductor plate 14 is inserted into the container 13. Then, the outer peripheral edge of the rubber plate 14b bends upward.

(Problems to be Solved by the Invention) As shown in FIG. 9, when the inductor plate 14 is pulled up inside the container 13, the inductor plate 14 adheres to the inner wall of the container 13 (the rubber plate 14b is wiped down when it is lowered). The high-viscosity material (which could not be cut off) was scraped off by the outer peripheral edge of the rubber plate 14b bent upward and accumulated on the upper surface of the inductor plate 14, and when the inductor plate 14 was pulled out from the container 13, the high-viscosity material
17a is dirty around the container and workers.

Further, the inductor plate 14 has a conical portion 14e for collecting the high-viscosity material in the central portion thereof, so that the container 13
A high-viscosity material 17b having a shape corresponding to the conical portion 14e remains at the bottom of the, and waste occurs with the high-viscosity material 17a on the inductor plate 14.

Furthermore, the empty container 13 is disposed of, but since this container 13 is made of metal because it requires pressure resistance and is relatively large, it is time-consuming to dispose of and the economic loss is ignored. Can not.

The present invention has been made in view of the above circumstances, and it is possible to solve the problems of dirt due to a high-viscosity material, waste due to residual high-viscosity material, time and waste associated with the disposal of a container, and economical loss all at once. The purpose is.

[Structure of the Invention] (Means for Solving the Problems) The present invention relates to a pump main body 12 while pressurizing a high-viscosity material in a container.
A high-viscosity material container for a high-viscosity pump to be supplied to the inside of the outer box 22 that can withstand the pressurization, and an easily deformable inner bag provided with a high-viscosity material outlet 28 connected to the pump body 12. twenty three
Is inserted from the upper surface opening of the outer box 22, and is interposed between the pressing plate 33 integrally attached to the pump body 12 and the upper surface portion 27 of the inner bag 23 at the upper surface opening edge of the outer box 22. A high-viscosity material container for a high-viscosity pump having a plurality of flexible plates 26 fixed thereto.

(Operation) In the present invention, by pressing the upper surface portion 27 of the inner bag 23 via the flexible plate 26 by the pressing plate 33 integrated with the pump body 12,
The high-viscosity material inside the inner bag 23 is extruded from the high-viscosity material outlet 28 into the pump body 12. When the upper surface portion 27 of the inner bag 23 descends due to the decrease of the high viscosity material in the container, the side surface portion 34 of the inner bag 23 is folded back. The side surface portion 34 of the folded inner bag 23 is pulled upward by the flexible plate 26 that is relatively pulled out from the pressing plate 33, and an appropriate tension is generated in the inner bag 23.
The excess portion due to the contraction of the inner bag 23 does not become rounded or wrinkled under the pressing plate 33. The used inner bag 23 is
Discard as it is.

(Example) Hereinafter, the present invention will be described in detail with reference to the examples shown in FIGS. 1 to 5. In the high viscosity material pump, the same parts as those in the conventional example (Fig. 6) are designated by the same reference numerals as those in Fig. 6 and their description is omitted.

As shown in FIG. 1, the high-viscosity material container 21 has a metal outer box 22 having sufficient durability and an easily deformable inner bag 23 such as a thin film resin contained therein.

As shown in FIG. 4, a bottom plate 25 is integrally fitted to the lower portions of the outer box 22 and the outer plate 24, and a plurality of flexible plates 26 are formed, for example, in a radial pattern at the opening edge of the upper surface of the side plate 24. Is fixed. The flexible plate 26 is made deformable by being formed of a resin plate or the like having a large number of V grooves at regular intervals.

As shown in FIG. 5, the inner bag 23 is provided with a high-viscosity material outlet 28 on the upper surface portion 27, and a threaded portion 29 is formed around the high-viscosity material outlet 28. A lid (not shown) is screwed onto the screwing portion 29 during the distribution process. This screw part 29
Is projected upward through a notch 30 formed in the central portion of the plurality of flexible plates 26.

Then, as shown in FIG. 1, the outer box 22 capable of withstanding the pressurization of the high-viscosity pump is set on the base 10 of the high-viscosity pump, and the upper surface portion 27 of the inner bag 23 in the outer box 22 is set. Flexible plate
26 is placed, and the lower end of the pump body 12 is fitted into the high-viscosity material outlet 28 until the flange portion 31 formed integrally around the pump body 12 is engaged with the upper end of the screwing portion 29. And the connection union 32 engaged with the upper side of the flange 31 is screwed into the threaded portion 29.
32, the screw body 29 of the pump body 12 and the inner bag 23 and the pressing plate 33.
And are integrated. The pressing plate 33 presses the upper surface portion 27 of the inner bag 23 from above the flexible plate 26.

In this way, the flexible plate 26 is interposed between the pressing plate 33 integrally attached to the pump body 12 and the upper surface portion 27 of the inner bag 23.

Next, the operation of this embodiment will be described with reference to FIGS.

As shown in FIG. 1, an elevating mechanism 11 such as a fluid pressure cylinder erected on a base 10 is driven downward to press-fit a pump body 12 into an outer box 22 and integrate it with the pump body 12. By pressing the upper surface portion 27 of the inner bag 23 through the flexible plate 26 by the effective pressing plate 33, the high-viscosity material in this inner bag is transferred from the high-viscosity material outlet 28 of the inner bag 23 to the inside of the pump body 12. Is extruded into. The high-viscosity material is lifted by the pump mechanism in the pump body that is reciprocally moved by the pump driving unit 15, and is discharged from the high-viscosity material discharging unit 16.

As shown in FIG. 2, when the upper surface portion 27 of the inner bag 23 descends as the high-viscosity material in the container decreases, the side surface portion of the inner bag 23
34 is folded back down. The side of the folded inner bag 23
34 is pulled upward by the flexible plate 26 that is relatively pulled out from the pressing plate 33, and an appropriate amount of tension is generated. Never be.

FIG. 3 shows a state immediately before the upper surface portion 27 of the inner bag 23 comes into close contact with the lower surface portion 35, and finally, when the upper surface portion 27 and the lower surface portion 35 of the inner bag 23 descend until they come into close contact, almost all High viscosity material is discharged. At this time, since the lower surface portion 35 of the inner bag 23 facing the pump body 12 can be deformed upward by the negative pressure generated by the pump suction action, there is no waste of the high-viscosity material remaining in the container. Then, the used inner bag 23 is taken out from the outer box 22 and discarded as it is.

[Advantages of the Invention] According to the present invention, since the high-viscosity material does not leak to the outside of the inner bag, it is possible to prevent contamination by the high-viscosity material, and
Since the highly viscous material does not remain so much at the bottom of the easily deformable inner bag, waste of the highly viscous material can be prevented, and further, the inner bag can be easily disposed of and the economical loss is small. When the upper surface of the inner bag, which is easily deformable in the outer box, is pressed down by the pressing plate integral with the pump body and descends, the side surface of the inner bag is folded back. Since the flexible plate provided on the outer box gives an appropriate tension to the bag, the inner bag does not shrink due to the excess part of the inner bag shrinking that does not curl or wrinkle under the pressing plate. Smoothly, the high-viscosity material is reliably supplied from the inner bag to the pump body.
