DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for sucking a residual liquid of a liquid from a container containing a liquid material such as paint, petroleum, an adhesive and the like, and a residual liquid suction device used in the method. The present invention relates to a novel residual liquid suction method and apparatus capable of effectively suctioning residual liquid in a container by inclining the container without moving a suction port of a suction pipe inserted into the container, and particularly to a method for injecting an inlet. It is suitable when a drum with a top plate is used as a raw material container.

[0002]

2. Description of the Related Art Chemical plants and the like often require a step of supplying a liquid raw material from a raw material container containing a liquid raw material such as a paint or an adhesive to a processing container for performing preparation processing such as mixing and stirring. In the raw material supply step, a steel drum is often used as a raw material container, and a liquid material such as a paint or an adhesive is contained in the drum.

When a liquid material is supplied from a steel drum to a processing container, the liquid material is sucked up by a pump from a suction pipe inserted into an upper inlet of the drum and is supplied to the processing container via a feed pipe. At this time, since the liquid material is left at the bottom of the drum, the residual amount of the liquid material needs to be reduced as much as possible. In particular, when the liquid agent is an expensive raw material, the cost saving effect by reducing the residual liquid becomes remarkable.

[0004] Therefore, when the liquid material in the drum can is reduced and the weight of the entire drum becomes light, the drum can is tilted manually by using a part of the periphery of the bottom plate of the drum as a tilt fulcrum F. After the residual liquid in the drum can is collected at the inner corner of the inclined fulcrum F, the tip of the suction pipe is moved to the corner and the residual liquid is sucked by the pump, so that the pump unit is sandwiched from the drum. Thus, the liquid agent in the drum can was fed to the processing container with almost no residual through the connecting pipe connected to the processing container (see FIGS. 21 and 22).

However, in the drum canting mechanism of the above-mentioned bottom fulcrum type, when the drum can is tilted, the position of the inlet of the drum in which the suction pipe is inserted also moves as shown in FIG. The distance between the inlet and the suction port of the pump unit will change. Therefore, if the connecting pipe connecting the injection port of the drum can and the suction port of the pump unit is a steel pipe, the mounting portion of the connecting pipe may be detached or broken. When the connecting pipe is a flexible pipe, the connecting pipe can be bent and responded even if the distance changes, but the tip of the suction pipe is moved to the corner where the liquid agent in the drum can remains. In addition, it is necessary to perform a troublesome work of holding it there, and in addition, since the flexible tube is bent as shown in FIG. 22, the fluid friction at the time of sucking the liquid agent increases, and the discharge capability of the pump decreases. was there. Furthermore, since a normal drum can is very heavy, there is a problem that the work of inclining the drum can is a heavy labor for the on-site worker, and the work time is long.

[0006]

First, an apparatus according to a first embodiment of the present invention is shown in FIGS.
This will be described with reference to FIG. In the drawings, what is indicated by reference numeral 1 is a container for storing a liquid material E such as a paint or an adhesive. The container 1 is composed of a commercially available cylindrical metal drum that is widely used as a container for transporting and storing liquid raw materials. The drum is a JIS standard (a type M of JIS Z 1601) for a steel drum for liquid. Class). More specifically, a top plate 11 and a bottom plate 13 are fixed to the body 14 of the container 1, and an opening 12 and a vent 12 ′ are provided at predetermined positions of the top plate 11. The opening 12 serves as an inlet for injecting the liquid material and also serves as an insertion port for a suction pipe described later. In addition, the air port 12 'plays a role of allowing the air in the container 1 to communicate with the atmosphere so that the liquid material E can be smoothly injected and sucked. Further, chimes 11a and 13a having a predetermined height are protruded from the edges of the top plate 11 and the bottom plate 13. In the present embodiment, a polyester resin (viscosity at 25 ° C.) is used as the liquid agent E in the container 1.
It uses 700 cP (centipoise), solid content 40.0%) and polyisocyanate (viscosity at 25 ° C 20 cP (centipoise), solid content 52.5%).

Reference numeral 2 designates a suction pipe inserted into the container 1 from the opening 12 of the container 1 and is made of stainless steel (SUS304) having a diameter slightly smaller than the inner diameter of the opening 12. It has been produced. The tip of the suction pipe 2 is a suction port 21 from which the liquid E in the container 1 is sucked. A check valve 22 is provided near the suction port 21 to prevent the sucked liquid E from flowing back. At the other end of the suction pipe 2, a connection portion 23 of a substantially L-shaped pipe is provided.
Is connected to the suction port of the pump P. This pump P
Is disposed above the vicinity of the opening 12 of the container 1 in a state of being fixed to a support standing upright in the vicinity of the container 1 as shown in FIG. From the outlet, the liquid is fed to the processing vessel V (not shown) of the next process through the feed pipe T. As the pump P, an air-driven diaphragm pump is used. By using an air-driven pump, the pump P can be used safely even in an explosive atmosphere.

Next, what is indicated by reference numeral 3 is a mounting base, what is indicated by reference numeral 4 is an inclined plate, and what is indicated by reference numeral 5 is an inclination operating portion. A container tilting mechanism (3, 4, 5) is constituted by the mounting base 3, the tilting plate 4, and the tilting operation unit 5, and the container 1 containing the liquid E is tilted by the container tilting mechanism. Thereby, the residual liquid e of the liquid agent E remaining in the container 1 is collected at the inner bottom corner of the container 1. The remaining liquid e is sucked up by the pump P from the suction port 21 of the suction pipe 2 so that the liquid agent E hardly remains in the container 1. Hereinafter, each component of the container tilting mechanism will be described in detail.

The mounting base 3 of the container tilting mechanism (3, 4, 5) is a base for mounting the container 1 made of a heavy steel drum. As shown in FIG. 4, the mounting base 3 is formed in a substantially U-shape by processing a metal plate into a sheet metal.
The upper surface is provided with six rollers 31, 31... And two stoppers 32, 32. These rollers 31
With the stoppers 32, the heavy container 1 is placed on the mounting base 3 and moved until it hits each stopper 32, and the container 1 is rotated around the axis to open the opening 12 of the container 1. The operation of adjusting to the insertion position of the suction pipe 2 can be performed easily and accurately. Also,
At a predetermined position on the upper surface of the mounting base 3, a columnar pipe elevating unit described later is erected, and the above-mentioned diaphragm pump P is attached to this pipe elevating unit.

The inclined plate 4 is a plate for inclining the container 1 by contacting the back surface of the bottom plate 13 of the container 1 and the inner peripheral surface of the chime 13a at the edge thereof. 5 and 6 are views of the inclined plate 4 viewed from the back side,
As shown in these drawings, the inclined plate 4 is formed by processing a metal plate into a substantially rectangular lid shape by sheet metal working, and has four follower rollers 41, 41,.
.. Are provided. These follower rollers 41
.. Comes into contact with a linear motion cam of the tilt operating section 5 described later, and the motion of the tilt operating section 5 is transmitted to the tilt plate 4. On the side surface of the inclined plate 4, substantially L-shaped guide grooves 43 are formed symmetrically, respectively (see FIG. 6). Guide pins, which will be described later, are inserted into these guide grooves 43 to regulate the operation of the inclined plate 4. In addition, four roller shafts 42
The two rear roller shafts 42 are formed to be long, and the long roller shaft 42 is hooked with a pivoting hook of the tilting operation unit 5 described later to push out and tilt the inclined plate 4. Can be reliably returned to the original position.

The tilt operating section 5 is a member for operating the tilt plate 4 to tilt the container 1 at a predetermined angle. As shown in FIG. 7, the tilting operation section 5 includes a cylinder body 51 (in this embodiment, an air cylinder is employed) for performing a reciprocating operation, a reciprocating rod 52 mounted on the cylinder body 51, and a reciprocating rod 52. A connecting rod 53 connected to the end of the connecting rod 53, two linear motion cams 54 connected to both ends of the connecting rod 53, and rollers 54a pivotally supported at both ends of the linear cams 54. The two rails 55, 55 on which the linear motion cams 54, 54 run by rolling, and two inclined portions 56, having a 25-degree inclination angle, disposed in front of these rails 55, 55.
56 and two hooks 57 for pulling back the inclined plate 4 pivotally supported by the rear end rollers 54a of the linear motion cams 54.
・ 57 and a roller 57 provided at one end of the hooks 57
a.57a are mounted on and rolled with two pedestals 58.58.

Using the mounting base 3, the inclined plate 4, and the inclined operating portion 5 configured as described above, the inclined plate 4 is placed inside the U-shaped portion of the U-shaped mounting base 3, as shown in FIG. After being fitted from above, the rod-shaped guide pins 6 are inserted into the respective pin holes 33 on the side surface of the mounting base 3, and the ends of the respective guide pins 6 are inserted into the respective guide grooves 43 on the side surface of the inclined plate 4. When combined, the container tilting mechanism of the first embodiment is obtained. Note that FIG.
In addition, a part of the mounting base 3 is omitted from the drawing.

FIGS. 9 and 10 show the interior of the container tilting mechanism thus obtained. Each follower roller 41 pivotally supported on the inner side surface of the inclined plate 4 rests on the upper end surface of each linear motion cam 54 of the inclined operation unit 5, and when the linear motion cam 54 moves forward and backward in the cylinder body 51, Accordingly, the follower roller 41 slides on the translation cam 54. In this case, as shown in FIG. 10, since the outer shape of the translation cam 54 is formed in a curved shape (for example, the concave portion 54b, the slope portion 54c, the flat portion).
54d, stop portion 54e), the motion of the linear motion cam 54 is controlled by the inclined plate 4 via the follower roller 41 in accordance with the displacement of the curved shape.
Will be transmitted.

FIG. 4 shows a state change when the container 1 is tilted by the container tilting mechanism which skillfully utilizes the cam mechanism as described above.
This will be briefly described with reference to FIGS. First, FIG. 11 shows a state where the container 1 containing the liquid agent E is mounted on the mounting base 3. In this state, the reciprocating rod 52 of the tilt operating section 5 is retracted, and the follower roller of the tilt plate 4
41 is located in the concave portion 54b of the linear motion cam 54, and the upper end position of the inclined plate 4 is substantially flush with the lower end position of the bottom plate chime 13a of the container 1.

Next, when the reciprocating rod 52 is advanced (leftward in the drawing) from this state, as shown in FIG. 12, the follower roller 41 of the inclined plate 4 causes the inclined portion 54c of the linear motion cam 54 to move.
And the upper end surface of the inclined plate 4 comes into contact with the back surface of the bottom plate 13 of the container 1 exactly. Thereby, the container 1 can be stably inclined.

Next, when the reciprocating rod 52 is further advanced to move the front end roller 54a of the linear motion cam 54 near the lower end of the inclined portion 56, as shown in FIG. The inclined plate 4 hits the stopper 54e
Begins to tilt slightly.

Further, from this state, when the forward / backward rod 52 is advanced to move the front end roller 54a of the linear motion cam 54 near the upper end of the inclined portion 56, as shown in FIG. The position of the insertion port of the pipe 2 is hardly displaced, and the inclined plate 4 is inclined by about 4.5 to 5.0 degrees with respect to the horizontal plane, so that the bottom corner inside the container 1 is positioned almost directly below the opening 12 of the container 1. The level of the bottom corner is relatively lower than the level of other bottom corner portions. The residual liquid e of the liquid agent E in the container 1 flows down and gathers at the bottom corner where the relative level is low.
As a result, the suction pipe 2 inserted straight from the opening 12 of the container 1 does not cause a problem (positional displacement of the opening 12 of the container 1) due to the inclination of the container of the conventional bottom edge fulcrum type as shown in FIG. The relative level of the bottom corner of the container 1 close to the suction port 21 is reduced to a low level, and the liquid medicine remaining in the container 1 is collected around the suction port 21 and the residual liquid e
Can be effectively sucked from the suction port 21. In addition, when the liquid E of the container 1 was completely sucked by the suction pipe 2 while the container 1 was kept horizontal without using the container tilting mechanism of the present embodiment, about 2000 to 3000 cc of the liquid E was placed in the container 1. When the liquid E was suctioned using the container tilting mechanism of the present embodiment, the residual liquid E was approximately 200 to 300 cc (1
(1/0), a remarkable residual liquid suction effect was obtained, and it was possible to greatly reduce raw material costs.

In this embodiment, the container 1 is JI
A cylindrical steel drum that conforms to the S standard (class M of JIS Z 1601) is used.
The optimum angle of inclination for positioning the bottom corner where the relative level is low is approximately 4.5 to 5.0 degrees just below. This optimum tilt angle can be obtained by adjusting the mounting position of the tilt portion 56 of the tilt operating portion 5 and its tilt angle.
If the size of the container 1 or the position of the opening 12 changes, the optimum tilt angle naturally changes accordingly.

FIG. 15 shows an example in which a residual liquid suction device using such a container tilting mechanism is applied to a processing liquid supply system.
Description will be made with reference to FIG. In FIG. 15, a supply pipe T connects a processing vessel V provided in a liquid mixing stirrer M and a discharge port of a pump P, and one end of a suction pipe 2 is connected to a suction port of the pump P. A suction pipe 2 is inserted into the container 1. The container 1 is mounted on a mounting base 3 having a built-in container tilting mechanism. On the mounting base 3, a columnar pipe elevating unit 7 is erected near the container 1. The part 7 enables the suction pipe 2 and the pump P to move up and down. The pipe lifting / lowering unit 7 includes a cylinder body 71 (in this embodiment, an air cylinder is employed) for performing a lifting / lowering operation,
The container 1 is replaced with the lifting rod 72 attached to the container 71 while the lifting rod 72 is raised as shown in FIG. A control panel (not shown) is provided on the mounting base 3 with a support, and a changeover switch on the control panel automatically controls the raising / lowering operation of the pipe lifting / lowering unit 7 and the tilting operation of the container tilting mechanism. It is appropriately performed. In this embodiment, since all of the driving sources of the pump P, the container tilting mechanism, and the like have an explosion-proof structure using compressed air, the safety is high even in an explosive atmosphere in which flammable gas or the like exists.

Thus, the container 1 is tilted while the suction port 21 of the suction pipe 2 is stably held by moving the suction pipe 2 up and down in the vertical direction by the pipe lifting / lowering section 7 so as to be close to the suction port 21. In addition, the relative level of the bottom corner of the container 1 can be reduced to a low level, the residual liquid e in the container 1 can be effectively sucked, and the container 1 can be replaced easily and quickly. In addition, since the operation of tilting the container 1 made of a heavy drum can is mechanized by the container tilting mechanism of the present embodiment, the container can be released from the heavy labor of the conventional manual container tilting operation, and the container can be replaced by the conventional manual operation. Even if you do not tilt the container after confirming that the liquid in the container is low to reduce the overall weight of the container even a little, first tilt the heavy container full of liquid, then Until the liquid in the container is exhausted, it is possible to concentrate on other on-site work, and it is possible to greatly improve work efficiency. Further, since the pump P is disposed above the vicinity of the opening 12 (the insertion port of the suction pipe 2) of the container 1, the connection distance between the suction pipe 2 and the suction port of the pump P can be shortened, and the pump P The discharge capacity can be increased, and the installation space for the pump unit Pu required in the conventional processing liquid supply system shown in FIG. 21 can be saved.

Next, an apparatus according to a second embodiment of the present invention will be described with reference to FIG.
Description will be made with reference to FIG. The second embodiment differs from the first embodiment in that a container tilting mechanism having a simple structure without using a cam mechanism is employed. In the container tilting mechanism of the second embodiment, a front roller 44 and a rear roller 45 project downward from predetermined portions of the tilt plate 4, and these rollers 44, 45 have legs of different lengths. (The front roller 44 has a short leg and the rear roller 45 has a long leg). A connecting portion is provided on the rear side surface of the inclined plate 4.
46 is provided, and the distal end of the advance / retreat rod 52 of the cylinder body 51 is connected to the connecting portion 46. At a predetermined position of the pipe elevating section 7 (in a horizontal plane having substantially the same height as the top plate 11 of the container 1), a contact plate 8 is fixed, and the top plate 11 of the container 1 is fixed to the contact plate 8.
A part of the periphery is in contact, and the contact point becomes a fulcrum when the container is tilted.

Using such a container tilting mechanism, as shown in FIG.
When the front roller 44 is moved forward (to the left in the drawing), as shown in FIG. 18, the front roller 44 and the rear roller 45 with legs roll on a slope 56 having a predetermined curved surface, and the front roller 44
The container 1 is inclined about a portion which reaches the vicinity of the upper end of 56 and where a part of the periphery of the top plate 11 of the container 1 is in contact with the contact plate 8 as a fulcrum.
In this case, the inclination angle of the inclined plate 4 on which the container 1 is placed is about 4.5 to 5.0 degrees with respect to the horizontal plane as in the first embodiment, and the inclination angle of the opening 12 (the insertion port of the suction pipe 2) of the container 1 is set. The bottom corner where the relative level is low is positioned almost directly below the opening 12 of the container 1 with almost no displacement, and the suction port 21 of the suction pipe 2 is located near this bottom corner. Therefore, similarly to the first embodiment, the liquid agent E remaining in the container 1 can be effectively sucked, and the cost of raw materials can be significantly reduced.

Finally, the third embodiment of the present invention is shown in FIG.
Description will be made with reference to FIG. The third embodiment differs from the first embodiment in that an open drum can without the top plate 11 is used as the container 1. In the third embodiment, a cover 9 corresponding to the top plate 11 of the container 1 of the first embodiment is provided.
Is fixed to the upper part of the suction pipe 2. FIG. 19 shows the cover 9
FIG. 20 shows a state in which the suction pipe 2 is lowered, and FIG. 20 shows a state in which the suction pipe 2 is raised. This cover 9 prevents dust and the like from entering the container 1 even in an open drum can. As in the first embodiment, the liquid agent E in the container 1 is effectively sucked using the container tilting mechanism. Can be.

Although the embodiments of the present invention are generally as described above, the present invention is by no means limited to the above-described embodiments, and various modifications are possible within the scope of the claims. For example, a small-capacity gallon can can be used as the container 1 of the present embodiment other than the drum can, and the mounting base 3 on which the container 1 is placed is configured to be movable to further improve the work efficiency. It is possible to improve, and it is needless to say that any of these modified forms belongs to the technical scope of the present invention.

[0031]

As described above with reference to the embodiments,
According to the present invention, since the container tilting mechanism capable of holding the position of the suction pipe insertion port of the container is adopted instead of the conventional container tilting method using the bottom edge of the raw material container as a fulcrum, the raw material container is inserted into the raw material container. By simply moving the suction pipe up and down, the container can be inclined to effectively suction the residual liquid in the container, and the container can be replaced easily and quickly. Therefore, the practical value is extremely large in a work site using a drum or the like containing a liquid agent.
