Description

  The present invention relates to an apparatus used for installing a unit for filtering a molten metal such as aluminum in a can.

  As an apparatus for filtering a molten metal such as aluminum, for example, as shown in FIG. 21, a molten metal in which a plurality of porous filtration tubes 111 are supported between a pair of end plates 113 and 114 whose plate surfaces face each other. A filtration unit 110 is used. The filtration unit 110 is usually used by being installed in a ceramic container called a can body 120. A molten metal is stored in the can body 120, and the molten metal permeates into the inside from the outer surface of the filter tube 111. At that time, foreign matter in the molten metal is filtered.

  The filtration unit 110 is heavy because the end plates 113 and 114 and the filtration tube 111 constituting the filtration unit 110 are made of ceramics, and is easily broken by an impact. Since the can 120 is also made of ceramics, it can be easily broken by impact. Accordingly, as shown in FIG. 21, when the heavy filtration unit 110 is held by the jig 115 and lifted and the filtration unit 110 is installed in the can body 120, the positioning of the filtration unit 110 is not easy. During the lowering of the unit 110, the filtration unit 110 and the inner wall of the can 120 may come into contact with each other and be damaged.

  Even if the filtration unit 110 can be successfully installed in the can, the work for adjusting the position of the filtration unit 120 in the can 120 is also difficult. For example, a hydraulic setting jig described in Patent Document 1 is used to adjust the position of the filtration unit 110 in the can body 120. If this jig is used, the position adjustment of the filtration unit becomes easy to some extent, but the position adjustment may vary depending on the operator because the position adjustment is performed visually by the operator.

  The present invention will be described below based on preferred embodiments with reference to the drawings. FIG. 1 shows a molten metal filtration unit 10 to be installed in the present invention and a can body 20 in which the unit 10 is installed. A molten metal filtration unit (hereinafter, also simply referred to as “filtration unit”) 10 is an apparatus for filtering foreign substances contained in various metal melts including aluminum. The filtration unit includes a plurality of filtration tubes 11. The filtration tube 11 is made of a ceramic porous material, and a molten metal can flow between the inner and outer surfaces of the tube 11. Each filtration tube 11 has an opening 12 at one end in the longitudinal direction, and the other end is closed. Each filtration tube 11 is arranged in parallel to each other with its opening 12 directed in the same direction.

  In addition to the filtration tube 11, the filtration unit 10 includes a hot-water-side end plate 13 and a hot-water-side end plate 14 made of ceramics. The hot-water-side end plate 13 and the hot-water-side end plate 14 can be made of alumina ceramics, for example. The hot-water-side end plate 13 and the hot-water-side end plate 14 are arranged so that their plate surfaces face each other. Of the end portions in the longitudinal direction of each filtration tube 11 described above, the end portion having the opening 12 is supported by the tapping side end plate 14. At the same time, the closed end of each filtration tube 11 is supported by the hot-water-side end plate 13.

  The outlet side end panel 14 is provided with a plurality of openings penetrating in the thickness direction. The number of openings is the same as the number of filtration tubes 11 supported by the tapping side end plate 14. And the opening part 12 of each filtration tube 11 is exposed outside through the opening formed in the hot-water-side end plate 14.

  In the state in which the filtration unit 10 is installed in the can 20, the longitudinal direction of the filtration tube 11 faces the horizontal direction.

  The can body 20 in which the filtration unit 10 is installed is made of ceramics such as alumina ceramics, and has a substantially rectangular parallelepiped shape with an open top. The can body 20 has a space in which the filtration unit 10 can be installed. This space is defined by a bottom surface and four inner walls. Of the four inner walls, the pair of inner walls facing each other face the hot-water-side end plate 13 and the hot-water-side end plate 14 of the filtration unit 10 when the filtration unit 10 is installed. On the inner wall facing the hot water side end plate 14, at least a position corresponding to the opening formed in the hot water side end plate 14 is opened.

  In order to filter the foreign matter in the molten metal, the molten metal is supplied into the can with the filtration unit 10 installed in the can 20. The supplied molten metal permeates from the outer surface of the filtration tube 11 provided in the filtration unit 10 toward the inside. At this time, the foreign matter contained in the molten metal is removed. The molten metal that has permeated the inside of the filter tube 11 and has been filtered flows through the filter tube 11 and flows out through the opening 12. In FIG. 1, the direction of the two-dot chain line arrow indicates the flow direction of the molten metal.

  FIG. 2 is a schematic view showing an embodiment of an installation apparatus for installing the filtration unit 10 described above in the can body 20. The installation device 30 includes a horizontal member 32a horizontally spanned between the columns 31a and 31a, a horizontal member 32b horizontally spanned between the columns 31b and 31b, and the horizontal members 32a and 32b. And a crane beam 33 suspended in the horizontal direction.

  The installation apparatus 30 is roughly divided into four stages. Specifically, the first stage 1 is located outside the two columns 31a, 31a and in the back side of the drawing in FIG. The fourth stage 4 is located outside the two columns 31b and 31b and in front of the paper surface in FIG. The second stage 2 and the third stage 3 are located adjacent to each other in an area surrounded by the four support columns 31a and 31b. The second stage 2 is located adjacent to the first stage 1. On the other hand, the third stage 3 is located adjacent to the fourth stage 4.

  A pair of rails 34 parallel to each other are laid from the first stage 1 to the second stage 2. A shuttle 35 is installed on the rail 34, and the shuttle 35 can move on the rail 34. The shuttle 35 is configured to be rotatable in a horizontal plane around a vertical line. The can body 20 is placed on the shuttle 35, and the can body 20 can move between the first stage 1 and the second stage 2.

  From the fourth stage 4 to the third stage, a transfer device 36 such as a conveyor is installed. The filtration unit 10 is placed on the transfer device 36 so that the filtration unit 10 can move between the fourth stage 4 and the third stage 3.

  A crane 37 is installed between the second stage 2 and the third stage 3. The crane 37 is movable in the Y direction in the horizontal plane along the crane beam 33. At the same time, it is also movable in the X direction in the horizontal plane. The crane 37 is further movable up and down along the vertical direction Z.

  At the lower end of the crane 37, the filtration unit 10 can be attached and detached, and a gripping device 38 for installing the filtration unit 10 in the can 20 is attached. Details of the gripping device 38 will be described later.

  The installation method of the filtration unit 10 using the installation apparatus 30 having the above configuration will be described. First, as shown in FIG. 3, the can body 20 in which the filtration unit 10 is installed is carried into the first stage 1 and the first stage. 1 is placed on the shuttle 35 waiting at 1. When the can body 20 is placed on the shuttle 35, the shuttle 35 moves along the rail 34 and conveys the can body 20 to the second stage 2.

  The can body 20 transported to the second stage 2 is measured for the XY coordinates of the inner wall of the can body 20 by the inspection camera 39 installed on the second stage 2, and the dimension and position information of the inner wall is stored in the storage means ( (Not shown). Based on the measurement result of the XY coordinates, when the four inner walls of the can 20 are tilted from the XY direction, the shuttle 35 is vertically moved using a drive means (not shown) such as a servo motor. It is rotated around the line in a plane, and correction is performed to match the direction of the inner wall with the XY direction, and the corrected position information is stored.

  When the can body 20 conveyed to the second stage 2 is imaged by the inspection camera 39, the crane 37 is moved to be positioned immediately above the can body 20 as shown in FIG. The gripping device 38 described above is attached to the tip of the crane 37. Further, a length measuring sensor B is attached to the tip of the crane 37. Therefore, in this state, the gripping device 38 is located on the upper portion of the can body 20, and the gripping device 38 can be moved up and down. The crane 37 is lowered from this state, and as shown in FIG. 5, the tip of the crane 37 is inserted into the can body 20 in a state before the filtration unit 10 is installed together with the length measurement sensor B. Then, the inside of the can body 20 is scanned by the inserted length measurement sensor B, and the dimensions of the inside of the can body 20 are measured. Moreover, the positional information inside the can 20 is memorize | stored. The scanning result of the inside of the can 20 by the length measuring sensor B is sent to an arithmetic device (not shown). In the arithmetic unit, the state in the can 20 obtained by scanning is compared with the state set in advance, and the state in the scanned can 20 is out of the state set in advance. If so, a command to discharge the can 20 as a defective product is transmitted. Based on this discharge command, the can 20 is discharged out of the second stage 2 by a predetermined device.

  The length measuring sensor B measures the amount of inclination of the inner wall of the can body 20 in the vertical direction by scanning the inside of the can body 20. And according to the measured inclination amount, the inclination amount in the vertical direction of the end plate of the filtration unit 10 installed in the can 20 is adjusted. In particular, the amount of inclination of the hot water end end plate 14 is made to coincide with the amount of inclination of the inner wall facing the hot water end end plate 14. By making both the inclination amounts coincide, it is possible to effectively prevent the leakage of the molten metal. In order to adjust the amount of tilt of the end plate in the vertical direction, for example, a thin plate 40 for tilt adjustment (see FIG. 6) may be attached to either the bottom surface of the hot water side end plate 13 or the hot water end side end plate 14.

  Along with the attachment of the thin plate for adjusting the inclination, a gasket 41 (see FIG. 6) is attached to the outer surface of the tapping plate 14 in the filtration unit 10. The gasket 41 is composed of a rectangular annular body, and is attached so as to surround all the openings provided in the hot water end panel 14. The gasket 41 is made of alumina fiber, for example.

  When the measurement of the dimensions and the like in the can 20 is completed in the second stage 2, the filtration unit 10 is lifted by the loading crane 42 installed in the fourth stage 4 as shown in FIG. Is carried into the transfer device 36. Prior to loading into the transfer device 36, the gasket 41 described above is attached to the outer surface of the tapping plate 14.

  As shown in FIG. 6, when the filtration unit 10 is carried into the fourth transfer device 36 of the fourth stage, the end plate of the filtration unit 10 according to the amount of inclination of the inner wall of the can body 20 in the second stage 2 described above. A thin plate 40 is attached to the bottom. Next, the transport device 36 is operated to transport the filtration unit 10 to the third stage 3.

  If the filtration unit 10 is conveyed to the 3rd stage 3, the crane 37 (refer FIG. 2) will be moved and the holding | grip apparatus 38 will be located in the upper part of the filtration unit 10 as shown in FIG. This positioning can be performed visually by an operator. Alternatively, as shown in the figure, the filtration unit 10 is imaged by the camera 43 attached to the length measurement sensor B, the position of the filtration unit 10 imaged by the camera 43 is recognized, and the filtration unit 10 can be gripped. The gripping device 38 may be automatically moved to a position immediately above.

  When the gripping device 38 is positioned immediately above the filtration unit 10, the crane 37 is lowered to bring the gripping device 38 close to the filtration unit 10. The lowering of the gripping device 38 can be performed visually by an operator. Alternatively, based on the distance measurement result using the length measurement sensor B attached to the gripping device 38 or the length measurement sensor C (not shown) attached separately from the length measurement sensor B, the gripping device 38 is automatically lifted and lowered. Can be lowered. In this case, the length measuring sensor B or the length measuring sensor C can measure the distance between the gripping device 38 and the filtration unit 10. The gripping device 38 is configured to move up and down based on the distance L between the gripping device 38 and the filtration unit 10 measured by the length measurement sensor B or the length measurement sensor C, and to automatically grip the filtration unit 10. ing. For example, as shown in FIG. 7, the distance L can be measured based on the upper surface of the hot-water-side end plate 13 or the hot-water-side end plate 14.

  When the gripping device 38 is lowered to a position where the filtration unit 10 can be gripped, the clamp cylinder provided in the gripping device 38 is projected as shown in FIG. The protruding clamp cylinder 44 is inserted into openings formed in the end plates 13 and 14 of the filtration unit 10. By this insertion, the filtration unit 10 is gripped by the gripping device 38. When gripping is completed, the wedge 45 is detachably attached to the gripping device 38. Accordingly, the wedge 45 is installed in the can body 20 together with the gripping device 38 in a state of gripping the filtration unit 10. The number of attached wedges 45 is one or more. The purpose of use of the wedge 45 will be described later. The means for attaching the wedge 45 to the gripping device 38 is not particularly limited, and for example, manual operation by an operator or automatic attachment by a robot on the third stage can be used.

  When the filtration unit 10 is gripped by the gripping device 38 in this way, the crane 37 is raised and the filtration unit 10 is lifted. Next, the crane 37 is moved along the Y direction (see FIG. 2) and is positioned on the upper part of the second stage 2. The can 20 has already been placed on the second stage 2 by the previous operation, and the filtration unit 10 is arranged immediately above the can 20 as shown in FIG. This arrangement can be made visually by an operator. Or it can carry out automatically based on the dimension and position information of the can 20 measured by the operation shown in FIG.

  When the filtration unit 10 is disposed immediately above the can body 20, the crane 37 is lowered and the filtration unit 10 is installed inside the can body 20. The lowering of the filtration unit 37 can be performed by visual inspection of the operator. Alternatively, as shown in FIG. 10, the inner wall of the can body 20 is scanned by the length measuring sensor B descending together with the filtration unit 10, and the fine adjustment of the position is automatically performed so that the filtration unit 10 does not contact the inner wall of the can body 20. You can also lower it while doing it.

  Confirmation that the filtration unit 10 has settled in the can 20 can be performed by visual observation of the operator. Alternatively, the load cell (not shown) attached to a part of the descending crane is continuously measured, and the load cell load value falls below a threshold value, so that it is automatically determined that the bottom has reached the bottom. You can also.

  When it is confirmed that the filtration unit 10 has settled in the can 20, the clamp cylinder 44 in the gripping device 38 is pulled back to release gripping. Next, as shown in FIG. 11, the jack 46 is installed in the can 20. The jack 46 is inserted between the hot-water-side end plate 13 in the filtration unit 10 and the inner wall 20a of the can body facing it. The jack 46 is used to press the outlet end panel 14 of the filtration unit 10 installed in the can body 20 against the inner wall of the can body 20. For this purpose, the jack 46 can comprise, for example, one or more hydraulic cylinders 47. A hook portion 48 is provided on the upper portion of the jack 46, and the jack 46 is fixed to the hot water end side end plate 13 by engaging the hook portion 48 with the upper portion of the hot end side end plate 13.

  The jack 46 is installed in the can body 20 and the length measuring sensor A is installed in the can body 20. The length measuring sensor A has a structure that can be attached to and detached from the filtration unit 10. Four length measuring sensors A are attached at positions in the vicinity of the tapping plate 14 of the filtration unit 10. Specifically, it is attached to the left and right upper portions and the left and right lower portions in the vicinity of the outer surface of the hot water side end panel 14. Each length measuring sensor A is capable of measuring the distance between the inner wall 20b of the can body 20 facing the tapping side end panel 14 and the outer surface of the tapping side end panel 14. In FIG. 11, the jack 46 and the length measurement sensor A are separated from each other. Instead, the jack 46 and the length measurement sensor A are integrated into a single body. You may install in 20. Further, in FIG. 11 and FIG. 12 described below, the gripping device 38 and the wedge 45 are not shown.

  When the jack 46 and the length measurement sensor A are attached at predetermined positions, the hydraulic cylinder 47 of the jack 46 is operated to move the filtration unit 10 as shown in FIG. Press against the inner wall 20b. The hydraulic cylinder 47 is operated by operating a hydraulic pump 48. When the jack 46 has two or more hydraulic cylinders 47, it is preferable that each hydraulic cylinder 47 can be individually controlled. Thereby, it becomes easy to equalize the force which presses the tapping plate 14 against the inner wall 20b of the can 20.

  The operation of the hydraulic pump 48 is controlled by a control device 49. By operating the hydraulic cylinder 47, the distance between the outer surface of the tapping plate 14 and the inner wall 20b of the can body 20 gradually decreases. That is, the pressing amount when the filtration unit 10 is pressed against the inner wall 20b of the can 20 by the jack 46 gradually changes. The pressing is performed while the pressing amount is monitored by the length measuring sensor A. The amount of pressing is monitored by the control device 49 to which a signal from the length measuring sensor A is connected. When the pressing of the filtration unit 10 by the jack 46 reaches a predetermined pressing amount, an operation stop signal is transmitted from the control device 49 to the hydraulic pump 48. The hydraulic pump 48 that has received the signal stops operating, and the jack 46 maintains the previous pressing.

  In this state, as shown in FIG. 13, the wedge 45 previously attached to the gripping device (not shown) is removed from the gripping device. The wedge 45 is used for maintaining the pressing state of the filtration unit 10 in a state where the wedge 45 is pressed against the inner wall 20b of the can body 20 to a predetermined pressing amount by the jack 46. The wedge 45 is made of ceramics such as alumina, for example.

  The wedge 45 falls by being detached from the gripping device, and is inserted between the outer surface of the hot-water-side end panel 13 and the inner wall 20 a of the can body 20. Since the wedge 45 is a heavy object, the wedge 45 is securely fitted between the outer surface of the hot-water-side end plate 13 and the inner wall 20a of the can body 20 by energy generated by the fall. By this fitting, the close contact state between the outer surface of the tapping plate 14 of the filtration unit 10 and the inner wall 20b of the can body 20 through the gasket 41 is reliably maintained, and the leakage of the molten metal is effectively performed. Is prevented. If necessary, the wedge 45 in the fitted state may be fitted deeper using a tool such as a hammer. In FIG. 13, the hydraulic pump is not shown for convenience of explanation.

  When removing the wedge 45 from the gripping device, the operator may perform it manually. Alternatively, for example, the gripping device receives a removal signal transmitted from the control device 49 and automatically removes the wedge 45 so that the wedge 45 is attached to the outer surface of the hot-water-side end plate 13 of the filtration unit 10 and the can 20. It may be configured to be automatically inserted between the inner wall 20a.

  When the fitting of the wedge 45 is completed, the pressure of the hydraulic pump 48 is released according to a command from the control device 49, and the pressing by the jack 46 is released. Next, the jack 46 and the length measuring sensor A are taken out from the can body 20, and a gripping device (not shown) is lifted and retracted above the can body 20. The jack 46 and the length measuring sensor A may be taken out by an operator using a crane or the like, or may be taken out automatically. In this way, the installation of the filtration unit 10 in the can 20 is completed. Next, the shuttle 35 (see FIG. 2) is operated to move the can 20 from the second stage 2 to the first stage 1. The can 20 moved to the first stage 1 is lifted and carried out by a carrying-out crane (not shown). Thereafter, the operations described so far are repeated.

  In FIG. 11, the jack 46 and the length measurement sensor A are installed in the can body 20 separately from the gripping device 38, but instead the jack 46 is detachable from the gripping device 38. The jack 46 may be installed in the can 20 together with the filtration unit 10 held by the holding device 38. By doing so, the installation of the filtration unit 10 can be further automated. Alternatively, the length measuring sensor A may be attached to the gripping device 38, and the length measuring sensor A may be attached to the filtration unit 10 when the gripping device 38 grips the filtration unit 10. By doing so, the installation of the filtration unit 10 can be further automated.

  The wedge 45 shown in FIG. 13 is inserted using the dead weight of the wedge 45, but instead, the wedge 45 may be actively inserted by applying an external force. For example, as shown in FIG. 14, a winch 51 is installed immediately above the wedge 45, and the weight 50 is moved up and down by the winch 51. When the weight 50 is raised, the wire attached to the weight 50 is wound around the winch 51 and wound up. When the weight 50 is lowered, the rotating shaft of the winch 51 is placed in an unloaded state, and the weight 50 is freely dropped toward the upper end surface of the wedge 45. Then, the wedge 45 is inserted between the outer surface of the hot-water-side end plate 13 and the inner wall 20 a of the can body 20 by the energy when the free-falling weight 50 collides with the wedge 45.

  The degree of insertion of the wedge 45 can be monitored by a length measuring sensor 52 installed below the winch 51, for example, as shown in FIG. The length measuring sensor 52 can measure the distance to the upper surface of the weight 50 by emitting laser light. When the signal from the length measuring sensor 52 when the winding of the weight 50 and the free fall are repeated is processed, for example, a graph shown in FIG. In the graph shown in the figure, for example, when the difference between the value of the position on the vertical axis and the value of the previous position becomes smaller than the set value, it is determined that the wedge 45 has been inserted to a predetermined depth. be able to.

  The degree of insertion of the wedge 45 can also be measured by using the vibration sensor 53 shown in FIG. 17 instead of using the length measuring sensor 52 shown in FIG. The vibration sensor 53 is disposed in the vicinity of the upper end surface of the can body 20 and in the vicinity of the position where the weight 50 falls. The vibration sensor 53 measures vibration generated when the weight 50 falls freely and collides with the wedge 45. When the signal from the vibration sensor 53 when the winding of the weight 50 and the free fall are repeated is processed, for example, a graph shown in FIG. 18 is obtained. In the graph shown in the figure, for example, when the value of the amplitude of vibration on the vertical axis satisfies the set value, or when the duration of vibration on the horizontal axis satisfies the set value, the wedge 45 reaches a predetermined depth. It can be determined that it has been inserted.

  The wedge 45 can be inserted using a caulking device 54 as shown in FIG. 19 instead of using the free fall of the weight 50 shown in FIG. As the crimping device 54, for example, a hydraulic device including a cylinder 55 and a piston 56 can be used. The cylinder 55 and the piston 56 are attached to the caulking device 54 so that the forward / backward direction of the piston 56 coincides with the vertical direction. The piston 56 is positioned so that its lower end is in contact with the upper end of the wedge 45. Then, by driving the crimping device 54, the piston 56 is lowered toward the wedge 45 and the wedge 45 is pushed in. From the crimping device 54, a signal corresponding to the pushing pressure (load) and / or pushing position when the piston 56 pushes the wedge 45 is transmitted to a control device (not shown). By processing these signals in the control device that has received these signals, for example, a graph shown in FIG. 20 is obtained. In the graph shown in the figure, it can be determined that the wedge 45 has been inserted to a predetermined depth when, for example, the value of the pushing position on the vertical axis satisfies the set value. Alternatively, it can be determined that the wedge 45 has been inserted to a predetermined depth when the value of the indentation pressure (load) on the vertical axis satisfies the set value.

  As mentioned above, although this invention was demonstrated based on the preferable embodiment, this invention is not restrict | limited to the said embodiment.
