Description

Technical Field

[0001] The utility model relates to an impregnation treatment device. Background Art

[0002] The impregnation treatment is carried out using an impregnation tank containing an impregnation liquid. During the impregnation treatment, an impregnation basket containing a product to be coated with the impregnation liquid is impregnated in the impregnation tank. The impregnation liquid is volatile. In addition, the impregnation liquid is coated on the impregnation basket or the product in the impregnation tank. As a result, the impregnation liquid in the impregnation tank decreases over time. Summary of the Utility Model

[0003] Problems to be Solved by the Utility Model

[0004] When the impregnation liquid decreases, it is necessary to manually replenish the impregnation liquid into the impregnation tank. Conventionally, the administrator of the impregnation tank has to replenish the impregnation liquid into the impregnation tank with a relatively large height using, for example, a bucket. In addition, when replenishing the impregnation liquid, the operation of the impregnation treatment device stops, so the efficiency of the impregnation treatment decreases.

[0022] Hereinafter, embodiments of the present utility model will be described with reference to the drawings. Figure 1 It is a perspective view schematically showing the structure of the impregnation treatment device 1 in an embodiment of the present utility model. Figure 2 Corresponding to Figure 1 It is a partial perspective view showing a part of the impregnation treatment device 1 in perspective. Refer to Figure 1 And Figure 2, the impregnation treatment apparatus 1 includes an impregnation tank 10 for performing impregnation treatment, a storage tank 20 fluidly connected to the impregnation tank 10, and a replenishment tank 30 fluidly connected to the storage tank 20. When performing impregnation treatment, the impregnation basket 40 is immersed in the impregnation tank 10. In this example, the impregnation basket 40 is disposed above the impregnation tank 10.

[0023] The impregnation basket 40 is, for example, integrally formed in a cylindrical shape. In one example, the impregnation basket 40 has: a cylindrical main body portion 41 centered on the axis; and a pair of disk-shaped side wall portions 42, 42 that close both ends of the main body portion 41 in the direction along the axis. The main body portion 41 is formed of a mesh material, for example. The cylindrical accommodation space of the impregnation basket 40 is defined by the main body portion 41 and the pair of side wall portions 42, 42. The accommodation space is opened and closed by a lid (not shown) that can be opened and closed formed in the main body portion 41, for example.

[0024] A plurality of openings 43 are formed in the side wall portion 42. The main body portion 41 and the side wall portion 42 are formed of a metal material, for example. One or more products (articles) to be impregnated with the impregnation liquid in the impregnation tank 10 are accommodated in the accommodation space of the impregnation basket 40. In this state, when the impregnation basket 40 is immersed in the impregnation liquid in the impregnation tank 10, the impregnation liquid impregnates the accommodation space from the holes of the mesh of the main body portion 41 and the plurality of openings 43 of the side wall portion 42. By rotating the impregnation basket 40 about the axis, the impregnation liquid is coated on the surface of the article in the impregnation basket 40.

[0025] The impregnation tank 10 has an impregnation bath 11, a frame body 12 that supports the impregnation bath 11, and an overflow portion 13 disposed adjacent to the impregnation bath 11. The impregnation bath 11 defines a substantially semi-cylindrical accommodation space. The upper end of the accommodation space of the impregnation bath 11 is open to receive the impregnation basket 40. A predetermined amount of impregnation liquid L is accommodated in this accommodation space. During impregnation treatment, the impregnation basket 40 is immersed in the impregnation liquid L by descending from above the impregnation bath 11 into the impregnation bath 11. The impregnation bath 11 has a volume capable of accommodating at least a part of the impregnation basket 40.

[0026] The overflow portion 13 is connected to the impregnation bath 11 and is configured to discharge the impregnation liquid L that overflows from the impregnation bath 11 from the impregnation bath 11. Details of the overflow portion 13 will be described later. When discharging the impregnation liquid L, a discharge pipe 14 connected to the overflow portion 13 is used. The downstream end of the discharge pipe 14 is connected to the storage tank 20. The discharge pipe 14 may also be configured to be inclined downward from the impregnation bath 11 toward the storage tank 20 so that the impregnation liquid L can be transported from the impregnation bath 11 to the storage tank 20 by the action of gravity, for example.

[0027] The storage tank 20 has a storage tank 21 in the shape of a rectangular parallelepiped, for example. A predetermined amount of impregnating liquid L is stored in the storage tank 21. The downstream end of the discharge pipe 14 is connected to the storage tank 21. The impregnating tank 10 and the storage tank 20 are fluidly connected to each other through a circulation pipe 22 between the impregnating tank 11 and the storage tank 21 of the storage tank 20. The circulation pipe 22 can transport the impregnating liquid L from the storage tank 21 of the storage tank 20 to the impregnating tank 11 of the impregnating tank 10. A filter 23 can also be assembled in the circulation pipe 22. The filter 23 can filter out impurities and the like in the impregnating liquid L and remove them from the impregnating liquid L, for example.

[0028] When transporting the impregnating liquid L from the storage tank 21 to the impregnating tank 11, a circulation pump 50 assembled in the circulation pipe 22 is used. In this example, the circulation pump 50 is arranged on the upstream side of the filter 23 in the circulation pipe 22, that is, on the storage tank 20 side. The circulation pump 50 is, for example, a pneumatically driven diaphragm pump. Under the action of the circulation pump 50, the impregnating liquid L stored in the storage tank 21 of the storage tank 20 is transported to the impregnating tank 11 of the impregnating tank 10 via the circulation pipe 22.

[0029] The replenishing tank 30 has a replenishing tank 31 in the shape of a cylinder, for example. A predetermined amount of impregnating liquid L is stored in the replenishing tank 31. The storage tank 20 and the replenishing tank 30 are fluidly connected to each other through a replenishing pipe 32. The replenishing pipe 32 can transport the impregnating liquid L from the replenishing tank 31 of the replenishing tank 30 to the storage tank 21 of the storage tank 20. When replenishing the impregnating liquid L from the replenishing tank 31 to the storage tank 21, a replenishing pump 60 assembled in the replenishing pipe 32 is used. The replenishing pump 60 is, for example, a pneumatically driven diaphragm pump.

[0030] As Figure 2 shown, the downstream end of the discharge pipe 14 of the impregnating tank 10 can also be connected to a filter 24. In this example, the filter 24 is arranged, for example, in the storage tank 21 of the storage tank 20. However, the filter 24 can also be assembled between the upstream end and the downstream end of the discharge pipe 14. According to this filter 24, impurities and the like in the impregnating liquid L discharged from the impregnating tank 11 can be filtered out and removed from the impregnating liquid L.

[0031] Figure 3 is a side view schematically showing the structure of an impregnating tank 10 of a specific example. Figure 4 is along Figure 3 sectional view taken along line 4-4 of. Specifically, Figure 4 shows a sectional view of the impregnating tank 10 cut along a vertical plane. Referring also to Figures 1 to 4 , the overflow portion 13 has a flow path member 15 adjacent to the impregnating tank 11. In Figure 3 side view, the flow path member 15 is formed in a conical shape with the front end tapering as it goes from the upper end to the lower end. The flow path member 15 is formed in a funnel shape, for example. The upstream end of the discharge pipe 14 is connected to the lower end of the flow path member 15.

[0032] In particular, as Figure 4 shown, the dipping tank 11 has side walls 11a that are formed on the side walls of the flow path 16 of the flow path member 15. In this example, the side walls 11a extend along the axis of the semi-cylindrical shape of the dipping tank 11 over the entire length of the flow path member 15. The upper end of the side wall 11a is defined at a position P that is a predetermined distance from the bottom surface of the dipping tank 11. In a state where the dipping basket 40 is not dipped into the dipping tank 11, as Figure 4 shown, the position P1 of the liquid level LS of the dipping liquid L in the dipping tank 11 is defined at a position lower than the position P of the upper end of the side wall 11a.

[0033] Figure 5 And Figure 4 corresponding, is a cross-sectional view schematically showing a state where the dipping basket 40 is dipped in the dipping tank 11. As Figure 5 shown, when the dipping basket 40 containing an article is dipped into the dipping tank 11 in this accommodation space, due to the volume of the dipping basket 40 and the article, the liquid level LS of the dipping liquid L rises. When the liquid level LS exceeds the position P of the upper end of the side wall 11a, that is, reaches a position P2 higher than the position P, the dipping liquid L in an amount exceeding the position P flows over the upper end of the side wall 11a and into the flow path 16. In this way, the dipping liquid L is transported from the flow path member 15 to the storage tank 21 through the discharge pipe 14.

[0034] Figure 6 And Figure 7 are partial perspective plan views schematically showing the structure of the storage tank 20 according to a specific example. As Figure 6 shown, the accommodation space of the storage tank 21 is enclosed by a bottom plate 21a, a top plate 21b, and four side plates 21c. The storage tank 20 has a sensor 25 configured to detect the storage amount of the dipping liquid L stored in the storage tank 21. The sensor 25 is a float type sensor. The sensor 25 has: a float member 26 supported on the top plate 21b of the storage tank 21 and floating on the liquid level of the dipping liquid L; and a photoelectric sensor 27 provided on the top plate 21b of the storage tank 21.

[0035] The floating member 26 has a floating piece 26a floating on the liquid level of the dipping liquid L and a rod-shaped shaft 26b fixed to the upper end of the floating piece 26a. A part of the shaft 26b protrudes upward from the top plate 21b through an opening (not shown) formed in the top plate 21b. The float member 26 can move up and down in the vertical direction with respect to the top plate 21b according to the change in the level of the liquid level of the dipping liquid L, that is, according to the change in the storage amount of the dipping liquid L. In other words, according to the position of the float 26a floating on the liquid surface, the position of the upper end of the shaft 26b changes in the vertical direction.

[0036] The photoelectric sensor 27 can irradiate light B onto an irradiation path that intersects the movement path of the shaft 26b of the floating member 26. In Figure 6In the example shown, the light B irradiated from the photoelectric sensor 27 is reflected by the shaft 26b of the floating member 26 and received by the photoelectric sensor 27. When such reflected light B is detected, the sensor 25 can detect the presence of the shaft 26b on the irradiation path. In this example, by detecting the presence of the shaft 26b, it is detected that the impregnating liquid L is stored in the storage tank 21 in a storage amount exceeding the specified amount. The specified amount in this case is preset by adjusting the length of the shaft 26b or the like.

[0037] On the other hand, as Figure 7 shown, when the storage amount of the impregnating liquid L decreases and the floating member 26 moves downward in the vertical direction, the shaft 26b of the floating member 26 moves downward and out of the irradiation path of the light B irradiated from the photoelectric sensor 27. As a result, the sensor 25 can detect the absence of the shaft 26b on the irradiation path. In this example, by detecting the absence of the shaft 26b, it is detected that the impregnating liquid L is stored in the storage tank 21 in a storage amount not exceeding the specified amount. That is, it is detected that the storage amount of the impregnating liquid L in the storage tank 21 has decreased.

[0038] As Figure 6 and Figure 7 shown, a stirrer 28 is installed on the top plate 21b of the storage tank 21. The stirrer 28 has a motor 28a installed on the top plate 21b, a shaft 28b rotationally driven by the motor 28a, and a stirring body 28c installed at the front end of the shaft 28b. By driving the motor 28a to rotate the shaft 28b, that is, the stirring body 28c, the impregnating liquid L in the storage tank 21 is stirred.

[0039] Next, the usage method of the impregnating treatment device 1 will be described. Before the impregnating treatment, a plurality of articles to be impregnated in the impregnating liquid L are accommodated in the accommodation space of the impregnating basket 40. In the impregnating tank 10, the impregnating basket 40 is immersed in the impregnating liquid L by descending from above the impregnating tank 10 into the impregnating bath 11. The impregnating liquid L impregnates into the accommodation space of the impregnating basket 40 from the holes of the mesh of the main body portion 41 and the plurality of openings 43 of the side wall portion 42. In the impregnating bath 11, the position of the liquid level LS of the impregnating liquid L rises by the volume of the impregnating basket 40 and the plurality of articles.

[0040] When the position of the liquid level LS of the impregnating liquid L exceeds the position P of the side wall 11a of the impregnating bath 11, the impregnating liquid L overflows into the flow path 16 of the flow path member 15. The impregnating liquid L that has overflowed into the flow path 16 is transported from the flow path 16 to the storage tank 21 of the storage tank 20 through the discharge pipe 14. In this way, the storage amount of the impregnating liquid L in the storage tank 21 increases. Here, for example, due to the increase in the storage amount of the impregnating liquid L, the photoelectric sensor 27 of the sensor 25 detects the presence of the shaft 26b of the floating member 26. That is, it is detected that the storage amount of the impregnating liquid L in the storage tank 21 exceeds the specified amount.

[0041] In this case, in the storage tank 20, the circulation pump 50 operates to transport the immersion liquid L from inside the storage tank 21 toward the immersion tank 11 via the circulation pipe 22. As long as the presence of the shaft 26b in the irradiation path of the light B from the photoelectric sensor 27 is detected by the sensor 25, this transportation continues. In this way, the immersion liquid L transported from the immersion tank 11 to the storage tank 21 and stored in the storage tank 21 is transported in a manner that returns from the storage tank 21 to the immersion tank 11. That is, the immersion liquid L in the immersion tank 11 is transported from the immersion tank 11 to the storage tank 21 and then from the storage tank 21 to the immersion tank 11, thereby circulating between the immersion tank 11 and the storage tank 21.

[0042] When the storage amount of the immersion liquid L in the storage tank 21 becomes lower than the specified amount by transporting the immersion liquid L to the immersion tank 11, the sensor 25 detects that the shaft 26b does not exist in the irradiation path of the light B from the photoelectric sensor 27. At this moment, the operation of the circulation pump 50 stops. As a result, the transportation of the immersion liquid L from the storage tank 21 to the immersion tank 11 stops. In such a circulation of the immersion liquid L, the immersion process of the immersion basket 40 continues in the immersion tank 11. During the immersion process, for example, when the immersion basket 40 is immersed in the immersion tank 11, the immersion basket 40 rotates around its axis. In this way, the application of the immersion liquid L to the articles inside the immersion basket 40 is performed.

[0043] In the storage tank 20, the time is counted starting from the stop of the operation of the circulation pump 50. For example, due to the volatilization of the immersion liquid L and the application of the immersion liquid L to the immersion basket 40 and the articles, in the immersion tank 11, the amount of the immersion liquid L decreases with the repetition of the immersion process, that is, with the passage of time. Similarly, since the transportation of the immersion liquid L from the immersion tank 11 to the storage tank 21 decreases, in the storage tank 21, the storage amount of the immersion liquid L decreases with the passage of time. As a result, in the sensor 25, it is continuously detected that the shaft 26b does not exist in the irradiation path of the light B. The operation of the circulation pump 50 continues to be stopped.

[0044] In this way, when the count of the time elapsed since the stop of the operation of the circulation pump 50 exceeds a preset specified time, that is, when the storage amount of the immersion liquid L in the storage tank 21 does not exceed the specified amount within the preset specified time, the replenishment pump 60 in the replenishment tank 30 operates. By the operation of the replenishment pump 60, the immersion liquid L in the replenishment tank 31 is transported to the storage tank 21 via the replenishment pipe 32. In this way, the storage amount of the immersion liquid L in the storage tank 21 increases. It should be noted that the replenishment of the immersion liquid L to the replenishment tank 31 can be carried out at any time. That is, the replenishment can also be carried out during the transportation of the immersion liquid L from the replenishment tank 31 to the storage tank 21.

[0045] The impregnating liquid L is continuously supplied to the storage tank 21 until the presence of the shaft 26b is detected by the sensor 25. That is, it continues until the storage amount of the impregnating liquid L in the storage tank 21 exceeds a specified amount. When the presence of the shaft 26b is detected by the sensor 25, the operation of the supply pump 60 is stopped. As a result, the conveyance of the impregnating liquid L from the supply tank 31 to the storage tank 21 stops. Thus, the supply of the impregnating liquid L to the storage tank 21 is completed. Thereafter, in the impregnating treatment apparatus 1, the circulation of the impregnating liquid L between the impregnating tank 11 and the storage tank 21 and the supply of the impregnating liquid L from the supply tank 31 to the storage tank 21 are repeated.

[0046] According to the impregnating treatment apparatus 1 described above, when the liquid level LS of the impregnating liquid L in the impregnating tank 11 exceeds the specified position P, the impregnating liquid L in an amount exceeding the specified position P is conveyed to the storage tank 21. When the storage amount of the impregnating liquid L in the storage tank 21 exceeds the specified amount, the impregnating liquid L is conveyed in a manner of returning from the storage tank 21 to the impregnating tank 11. And when the storage amount of the impregnating liquid L in the storage tank 21 does not exceed the specified amount within a specified time, the impregnating liquid L is supplied from the supply tank 31 to the storage tank 21.

[0047] In this impregnating treatment apparatus 1, when the impregnating liquid L decreases in the impregnating tank 11 and the storage tank 21, the impregnating liquid L is automatically supplied from the supply tank 31 to the storage tank 21. As a result, in the impregnating tank 11, the impregnating liquid L in an amount reduced due to volatilization, coating on an article, etc. is automatically supplied. Thus, the amount of the impregnating liquid L in the impregnating tank 11 is stabilized. In addition, since the supply of this impregnating liquid L can also be carried out during the impregnating treatment in the impregnating tank 11, it is not necessary to stop the operation of the impregnating treatment apparatus 1. A decrease in the efficiency of the impregnating treatment can be prevented. Further, assuming that the impregnating liquid L is replaced, only the impregnating liquid L in the impregnating tank 11 needs to be replaced, so that the amount of waste of the impregnating liquid L can be reduced.
