Abstract
Description
Technical Field
[0001] The present invention relates to Glass parts cleaning device technology.
Background Art
[0002] In the manufacturing process of glass articles, as an example of a cleaning method for removing chips, dust, oil films, etc. adhering to the manufactured glass articles, for example, a method of spraying a cleaning liquid onto the glass articles by a cleaning device is known. When implementing such a cleaning method, since it is necessary to always maintain the cleaning liquid in a clean state, the used cleaning liquid is sent to a storage tank, and chips, etc. remaining in the cleaning liquid are filtered and removed, and then, a liquid supply device for supplying the cleaning liquid to the cleaning device again is generally used.
[0003] The above liquid supply device includes, for example, a liquid collection trough for collecting the cleaning liquid in which chips, etc. remain, a storage tank for temporarily storing the cleaning liquid collected by the liquid collection trough, and piping members that communicatively connect the liquid collection trough, the storage tank, and the cleaning device so that the cleaning liquid can circulate therebetween. The piping members include a first piping member that forms a flow path from the liquid collection trough to the storage tank, and a second piping member that forms a flow path from the storage tank to the cleaning device. Also, a suction pump and a filter are continuously arranged in the middle of the second piping member, and a mesh filter (see, for example, Patent Document 1) is provided at the connection portion between the storage tank and the second piping member. Then, the cleaning liquid in the storage tank is sucked by the suction pump, and first, chips, etc. of a relatively large size are removed by the mesh filter, and then, after fine chips, etc. are sufficiently removed by the filter, it is supplied to the cleaning device again.

Patent Document 1
[0005] In the liquid supply device having the configuration described above, depending on the suction force (flow rate) of the suction pump, the mesh filter provided at the connection point between the storage tank and the second piping member may be pulled towards the suction pump side and deformed into a convex shape (concave when viewed from the inside of the storage tank). In such cases, when the cleaning fluid in the storage tank flows into the second piping component via the mesh filter, residual debris in the cleaning fluid may agglomerate on the mesh filter, causing it to become clogged. As a result, poor suction of the cleaning solution by the suction pump occurred, making it difficult to adequately supply the filtered cleaning solution back to the cleaning device. This meant that the manufactured glass articles could not be thoroughly cleaned, potentially leading to a deterioration in the quality of those glass articles.
[0006] This invention has been made in view of the problems of the current situation described above, and aims to prevent clogging of the mesh filter installed in the storage tank. [Means for solving the problem]
[0007] The problems that this invention aims to solve are as described above, and the means for solving these problems will now be explained.
[0008] That is, the glass parts cleaning apparatus according to the present invention is a glass parts cleaning apparatus equipped with a liquid supply device, comprising: a storage tank for storing liquid; a suction pump for sucking the liquid stored in the storage tank; a piping member connecting the storage tank and the suction pump; a mesh filter provided at the connection portion between the storage tank and the piping member; and a holder for the mesh filter so as to prevent the mesh filter from deforming toward the suction pump side. Having multiple strip-shaped plates Equipped with a frame, The aforementioned plurality of strip-shaped plates areIn the aforementioned connection portion, extending toward the mesh filter side, Strip-shaped plate The tip of the mesh filter is spaced apart from the mesh filter. Furthermore, the frame has a fixing portion that fastens together with the mesh filter to secure itself to the storage tank. It is characterized by the following: With this configuration, even if the mesh filter installed at the connection point between the storage tank and the piping member is pulled towards the suction pump by the suction force (flow rate) of the suction pump and deformed into a convex shape (concave when viewed from the inside of the storage tank), the frame can maintain the shape of the mesh filter. Therefore, when the liquid in the storage tank (for example, a cleaning solution containing shavings, etc.) flows into the piping component through the mesh filter, it is possible to suppress the aggregation of shavings, etc. remaining in the cleaning solution onto the mesh filter, thereby preventing clogging of the mesh filter. As a result, it becomes possible to suppress the occurrence of insufficient flow rate in the suction pump, and for example, the cleaning solution filtered by the filtration filter can be sufficiently supplied back to the cleaning device, allowing the manufactured glass articles to be thoroughly cleaned and improving the quality of the glass articles. Furthermore, with this configuration, the frame can immediately maintain the shape of the mesh filter before the amount of deformation of the mesh filter increases, even when the mesh filter is pulled in by the suction force (flow rate) of the suction pump and attempts to deform toward the suction pump side. Furthermore, with this configuration, even if the cleaning fluid drawn in by the suction force (flow rate) of the suction pump and passing through the mesh filter unexpectedly pulsates, the shape of the mesh filter deforms slightly until it comes into contact with the tip of the frame, thereby absorbing the effects of the pulsation and preventing it from interfering with the suction force (flow rate) of the suction pump. Furthermore, with this configuration, when the mesh filter is pulled in by the suction force (flow rate) of the suction pump and attempts to deform toward the suction pump side, the frame can suppress this deformation from multiple directions, thereby more reliably maintaining the shape of the mesh filter.
[0009] Furthermore, according to the present invention Glass parts cleaning device In the above Strip-shaped plate It is formed in a strip shape, and the above Strip-shaped plate The width dimension is preferably larger than the mesh opening dimension of the mesh filter. With this configuration, the frame does not penetrate the mesh of the mesh filter, and the shape of the mesh filter can be more reliably maintained by the frame.
[0010] Furthermore, according to the present invention Glass parts cleaning device In the above Strip-shaped plate It is preferable that it be placed between the mesh filter and the suction pump. This configuration ensures that the frame reliably maintains the shape of the mesh filter, which is pulled in by the suction force (flow rate) of the suction pump and tends to deform towards the suction pump.
[0012] Furthermore, according to the present invention Glass parts cleaning device In this configuration, it is preferable that the mesh filter be formed in a convex dome shape on the side opposite to the suction pump. This configuration increases the rigidity of the mesh filter, thereby minimizing deformation of the mesh filter toward the suction pump due to the suction force (flow rate) of the suction pump. [Effects of the Invention]
[0013] The present invention provides the following effects: In other words, the liquid supply device according to the present invention can prevent clogging of the mesh filter installed in the storage tank. [Brief explanation of the drawing]
[0014] [Figure 1] This is a schematic cross-sectional view showing the overall configuration of a liquid supply device according to one embodiment of the present invention. [Figure 2] This is an enlarged cross-sectional view showing the mesh filter and its vicinity.
Mode for Carrying Out the Invention
[0015] Next, an embodiment of the present invention will be described with reference to FIGS. 1 and 2.
[0016] [Overall Configuration of Liquid Feeding Device 1] First, the overall configuration of the liquid feeding device 1 embodied according to this embodiment will be described with reference to FIG. 1. The liquid feeding device 1 circulates and filters the cleaning liquid W between a liquid collecting gutter 2, a storage tank 10, and a cleaning device 3, which will be described later, during the manufacturing process of a glass article (not shown), thereby removing chips, dust, oil films, etc. removed from the glass article and remaining in the cleaning liquid W used for cleaning, and supplying the cleaning liquid W in a clean state to the cleaning device 3 again.
[0017] Here, the configuration of the cleaning device 3 is not particularly limited. For example, as an example, a shower device can be mentioned. The cleaning device 3 can be provided in plurality, for example, and sprays the cleaning liquid W onto the glass article.
[0018] The liquid feeding device 1 mainly includes a liquid collecting gutter 2, a storage tank 10, a piping member 20, a suction pump 30, a filtration filter 40, a mesh filter 50, and a frame 60 (see FIG. 2), etc.
[0019] The liquid collecting gutter 2 is for collecting the cleaning liquid W in which chips, etc. used for cleaning the glass article remain. Above the liquid collecting gutter 2, the cleaning device 3 is arranged, and above the liquid collecting gutter 2 and below the cleaning device 3, a conveyance path (not shown) through which the glass article passes is provided.
[0020] As the glass article passes through the above conveyance path, the cleaning liquid W is sprayed from the cleaning device 3 toward the liquid collecting gutter 2, whereby the glass article is cleaned with the cleaning liquid W, and the cleaning liquid W used for cleaning is collected in the liquid collecting gutter 2.
[0021] The storage tank 10 temporarily stores the cleaning liquid W discharged from the liquid collection trough 2. A storage tank side inlet 10a is provided at the top of the storage tank 10 (in this embodiment, the top plate portion 10c). A storage tank side outlet 10b is provided at the bottom of the storage tank 10 (in this embodiment, the bottom surface portion 10d).
[0022] The cleaning liquid W discharged from the liquid collection trough 2 is then supplied to the storage tank 10 via the storage tank side inlet 10a. Furthermore, the cleaning fluid W temporarily stored in the storage tank 10 is discharged from the storage tank 10 via the storage tank side outlet 10b.
[0023] The piping member 20 connects the liquid collection trough 2, the storage tank 10, and the cleaning device 3 so that the cleaning liquid W can be circulated between these members 2, 3, and 10. The piping member 20 includes a first piping member 21 that forms a flow path from the liquid collection trough 2 to the storage tank 10, and a second piping member 22 that forms a flow path from the storage tank 10 to the cleaning device 3.
[0024] The first piping member 21 is connected at one end to the liquid collection trough side outlet 2a provided in the liquid collection trough 2, and at the other end to the storage tank side inlet 10a of the storage tank 10. Furthermore, the second piping member 22 is connected at one end to the storage tank side outlet 10b of the storage tank 10, and at the other end to the cleaning device 3.
[0025] The cleaning liquid W in the storage tank 10 is then forcibly discharged by the suction pump 30 (described later) and supplied to the cleaning device 3 through the second piping member 22.
[0026] The suction pump 30 sucks and discharges the cleaning liquid W stored in the storage tank 10, and also supplies the cleaning liquid W back to the cleaning device 3. The suction pump 30 is positioned in the middle of the second piping member 22. In other words, the second piping member 22 connects the storage tank 10 and the suction pump 30.
[0027] The suction pump 30 then sucks the cleaning liquid W from the storage tank 10 and supplies the cleaning liquid W to the cleaning device 3 through the second piping member 22.
[0028] The filtration filter 40 filters the cleaning solution W to remove any shavings or other debris removed from the glass article that remain in the cleaning solution W. The filtration filter 40 is positioned in the middle of the second piping member 22, on the downstream side in the flow direction of the cleaning liquid W relative to the suction pump 30.
[0029] The cleaning solution W, which is then sucked up by the suction pump 30 and discharged from the storage tank 10, is filtered as it passes through the filtration filter 40. As a result, any shavings or other debris removed from the glass article that remain in the cleaning solution W are thoroughly removed by the filtration filter 40, and the cleaning solution W becomes clean.
[0030] The mesh filter 50 removes relatively large shavings and other debris remaining in the cleaning solution W before filtering the cleaning solution W with the filtration filter 40. The mesh filter 50 is formed, for example, in a dome shape that is roughly hemispherical, and its mesh opening dimension is set to a range of 1 mm to 15 mm in this embodiment.
[0031] The mesh filter 50 is positioned on the bottom surface 10d of the storage tank 10 so as to cover the storage tank side outlet 10b at the connection point between the storage tank 10 and the piping member 20 (more specifically, the second piping member 22), i.e., the storage tank side outlet 10b. Specifically, the mesh filter 50 is positioned so as to be convex on the opposite side from the suction pump 30, i.e., upward, relative to the outlet 10b on the storage tank side, and is fixed to the bottom surface 10d of the storage tank 10 using fastening members 52 via mounting seats 51 (see Figure 2) provided on its periphery.
[0032] In this manner, when the mesh filter 50 is fixed to the storage tank 10, it is formed in a convex dome shape on the side opposite to the suction pump 30, thereby increasing the rigidity of the mesh filter 50 and minimizing deformation of the mesh filter 50 toward the suction pump 30 due to the suction force (flow rate) of the suction pump 30.
[0033] Then, the cleaning liquid W in the storage tank 10 is first sucked up by the suction pump 30 and discharged through the outlet 10b on the storage tank side, at which point it is filtered by the mesh filter 50 to remove any relatively large shavings or other debris remaining in the cleaning liquid W. Subsequently, the cleaning solution W discharged from the storage tank 10 is filtered again by the filtration filter 40 to remove any remaining fine debris or other impurities from the cleaning solution W. As a result, the cleaning solution W becomes sufficiently clean and is supplied again to the cleaning device 3.
[0034] In this embodiment, the suction force (flow rate) of the suction pump 30 is set to approximately 200 liters / minute, and the diameter of the second piping member 22 through which the cleaning liquid W sucked up by the suction pump 30 flows is set to within the range of 10 mm to 100 mm.
[0035] Consequently, the force of the cleaning solution W as it passes through the mesh filter 50 is relatively strong, and since the cleaning solution W contains shavings and other debris of various sizes, the mesh filter 50 was sometimes pulled towards the suction pump 30 and deformed into a convex shape (concave when viewed from the inside of the storage tank 10).
[0036] In such cases, when the cleaning liquid W in the storage tank 10 flows into the second piping member 22 via the mesh filter 50, shavings and other debris remaining in the cleaning liquid W can agglomerate on the mesh filter 50, causing the mesh filter 50 to easily become clogged, which can lead to insufficient flow rate from the suction pump 30.
[0037] Therefore, in the liquid supply device 1 of this embodiment, a frame 60 is provided to hold the mesh filter 50 so as to prevent the mesh filter 50 from deforming toward the suction pump 30, thereby preventing deformation of the mesh filter 50 as described above.
[0038] With this configuration, even if the mesh filter 50 provided at the connection point between the storage tank 10 and the second piping member 22 (more specifically, the storage tank side outlet 10b) is pulled towards the suction pump 30 by the suction force (flow rate) of the suction pump 30 and deforms into a convex shape (concave shape when viewed from the inside of the storage tank), the frame 60 can maintain the shape of the mesh filter 50.
[0039] Therefore, when the cleaning liquid W in the storage tank 10 flows into the second piping member 22 via the mesh filter 50, the shavings and other debris remaining in the cleaning liquid W only adhere slightly to the vicinity of the mounting seat 51 (see shavings Q in Figure 2), thereby suppressing the aggregation of the shavings in the mesh filter 50 and preventing clogging of the mesh filter 50.
[0040] As a result, it becomes possible to suppress the occurrence of insufficient flow rate in the suction pump 30, and for example, the cleaning solution W filtered by the filtration filter 40 can be sufficiently supplied back to the cleaning device 3, thereby thoroughly cleaning the manufactured glass articles and improving the quality of the glass articles.
[0041] Further details regarding the configuration of frame 60 will be described later.
[0042] [Frame 60 Configuration] Next, the configuration of frame 60 will be explained in detail using Figure 2. In this embodiment, for example, the frame 60 is formed from a SUS material for rust prevention. Furthermore, the frame 60 comprises a plurality of rectangular strip-shaped plates 61, 61, ... (four in this embodiment) extending to one side, and a mounting base 62, and these plurality of strip-shaped plates 61, 61, ... are connected to the mounting base 62.
[0043] Specifically, the mounting seat 62 is a plate-shaped member (for example, rectangular or disc-shaped) formed from a flat SUS member, and a through hole 62a, approximately the same size as the storage tank side outlet 10b, is provided in its center. Furthermore, the multiple strip-shaped plates 61, 61, ... are arranged at equal intervals from each other along the periphery of the through-hole 62a, and each strip-shaped plate 61 is integrally formed with the mounting seat 62 so as to extend diagonally toward the horizontal center of the through-hole 62a and toward the mesh filter 50 side.
[0044] These multiple strip-shaped plates 61, 61, ... are arranged inside the mesh filter 50 fixed to the storage tank 10, so as to extend toward the upper center of the mesh filter 50. Furthermore, these multiple strip-shaped plates 61, 61, ... are arranged such that their tip portions 61a, 61a, ... are spaced apart from each other.
[0045] These multiple strip-shaped plates 61, 61, ... are positioned so that the through-holes 62a of the mounting seats 62 are coaxial with the outlet 10b on the storage tank side, and are fastened together with the mounting seats 51 of the mesh filter 50 to the bottom surface 10d of the storage tank 10 using fastening members 52 via the mounting seats 62. In other words, the mounting base 62 functions as a fixing part that secures these multiple strip-shaped plates 61, 61, ... to the storage tank 10.
[0046] Thus, in this embodiment, since multiple strip-shaped plates 61, 61, ... are arranged at the storage tank side outlet 10b located between the mesh filter 50 and the suction pump 30 (see Figure 1), for example, when the mesh filter 50 is pulled in by the suction force (flow rate) of the suction pump 30 and deforms into a convex shape (concave shape when viewed from the inside of the storage tank) towards the suction pump 30, these multiple strip-shaped plates 61, 61, ... are positioned on the side where the mesh filter 50 is about to deform. Therefore, these multiple strip-shaped plates 61, 61, ... can immediately suppress deformation of the mesh filter 50 as described above, and reliably maintain the shape of the mesh filter 50.
[0047] Furthermore, as described above, the multiple strip-shaped plates 61, 61, ... are arranged at the storage tank side outlet 10b, which is the connection point between the storage tank 10 and the second piping member 22, so that they extend toward the opposite side from the suction pump 30, i.e., toward the upper center of the mesh filter 50. Therefore, even if the suction force (flow rate) of the suction pump 30 causes the mesh filter 50 to deform into a convex shape toward the suction pump 30 (concave when viewed from the inside of the storage tank), the tips 61a, 61a, ... of these multiple strip-shaped plates 61, 61, ... immediately come into contact with the mesh filter 50 before the amount of deformation of the mesh filter 50 increases, thus ensuring that the shape of the mesh filter 50 is reliably maintained.
[0048] Furthermore, as described above, the multiple strip-shaped plates 61, 61, ... are fastened together with the mounting seat 51 of the mesh filter 50 via the mounting seat 62 and fixed to the bottom surface 10d of the storage tank 10, so even in a space-saving location, the mounting seat 62 Through this, these multiple strip-shaped plates 61, 61, ... can be securely fixed at a predetermined position (the outlet 10b on the storage tank side of the bottom surface 10d). Furthermore, when fixing these multiple strip-shaped plates 61, 61, ... between the mesh filter 50 and the suction pump 30, the multiple strip-shaped plates 61, 61, ... can be securely fixed via the mounting base 62 without being affected by the suction force (flow rate) of the suction pump 30.
[0049] In this embodiment, the width dimension of each rectangular strip-shaped plate 61 is set to be larger than the mesh opening dimension of the mesh filter 50. With this configuration, for example, even when the tip 61a of the strip-shaped plate 61 comes into contact with the mesh filter 50 which has begun to deform due to the suction force (flow rate) of the suction pump 30, the strip-shaped plate 61 will not penetrate the mesh of the mesh filter 50, and the shape of the mesh filter 50 can be more reliably maintained by the strip-shaped plate 61.
[0050] Furthermore, within the mesh filter 50 fixed to the storage tank 10, the length of each frame 60 is set such that the tip 60a of the frame 60 is slightly separated from the mesh filter 50. With this configuration, for example, even if the cleaning fluid W drawn in by the suction force (flow rate) of the suction pump 30 and passing through the mesh filter 50 suddenly pulsates, the shape of the mesh filter 50 deforms slightly until it comes into contact with the tip 61a of each strip-shaped plate 61, thereby absorbing the effect of the pulsation, and thus not hindering the suction force (flow rate) of the suction pump 30.
[0051] These multiple strip-shaped plates 61, 61, ... are arranged inside the mesh filter 50 fixed to the storage tank 10, extending toward the upper center of the mesh filter 50. Furthermore, as described above, these multiple strip-shaped plates 61, 61, ... are arranged so that their respective tip portions 61a are spaced apart from each other. Since shavings and glass powder tend to settle at the bottom 10d of the storage tank 10, and the cleaning solution W is sucked up by the suction pump 30, the sides of the mesh filter 50 are particularly prone to clogging. With this configuration, a space is secured above the through hole 62a where the tips 61a are spaced apart from each other, so even if the sides of the mesh filter 50 become clogged, the cleaning solution W can continue to be sucked up by the suction pump 30 from the top of the mesh filter 50 through the aforementioned space.
[0052] Furthermore, the number of strip-shaped plates 61 is not limited to multiple plates as in this embodiment; a single strip-shaped plate 61 may be provided. However, as in this embodiment, by providing a configuration in which multiple strip-shaped plates 61, 61, ... are provided, for example, when the mesh filter 50 is pulled in by the suction force (flow rate) of the suction pump 30 and attempts to deform toward the suction pump 30, these multiple strip-shaped plates 61, 61, ... can suppress the deformation from multiple directions, thereby more reliably maintaining the shape of the mesh filter 50.
[0053] Furthermore, the number of strip-shaped plates 61 is not limited to four. For example, if there are between three and eight strip-shaped plates, multiple strip-shaped plates 61, 61, ... can effectively suppress the mesh filter 50 from being pulled in by the suction force (flow rate) of the suction pump 30 and deforming towards the suction pump 30 without obstructing the flow of the cleaning fluid W.
[0054] Although embodiments of the present invention have been described above, the present invention is not limited in any way to these embodiments, but is merely illustrative. It can be implemented in various other forms without departing from the spirit of the invention, and the scope of the present invention is indicated by the claims, and further includes all modifications within the meaning and scope of equivalents as described in the claims.
