Hereinafter, the present invention will be described with reference to the drawings based on preferred embodiments thereof. In Fig. 1, a molten metal filter unit 10 to be installed in the present invention and a can body 20 in which the unit 10 is provided are shown. The molten metal filter unit (hereinafter also referred to simply as "filter unit") 10 is a device for filtering foreign matter contained in a molten metal of various metals typified by aluminum. The filter unit includes a plurality of filter tubes 11. The filter tube 11 is made of a ceramic porous material, and the molten metal can flow between the inner and outer surfaces of the tube 11. Each of the filter tubes 11 has an opening portion 12 at one end in the longitudinal direction thereof, and the other end is closed. Each of the filter tubes 11 has its opening portions 12 arranged in parallel with each other in the same direction.

The filter unit 10 includes, in addition to the filter tube 11, a ceramic inlet side end plate 13 and a liquid discharge side end plate 14. The liquid inlet side end plate 13 and the liquid discharge side end plate 14 may be made of, for example, alumina ceramic. The liquid inlet side end plate 13 and the liquid discharge side end plate 14 are disposed such that the plates thereof face each other. The end portion having the opening portion 12 in the longitudinal direction end portion of each of the filter tubes 11 described above is supported by the liquid discharge side end plate 14. At the same time, the closed end of each filter tube 11 is supported by the liquid-inlet side end plate 13.

The liquid discharge side end plate 14 is provided with a plurality of openings penetrating in the thickness direction thereof. The number of openings is the same as the number of the filter tubes 11 supported on the discharge side end plate 14. Further, the opening portion 12 of each of the filter tubes 11 is exposed to the outside through an opening formed in the liquid discharge side end plate 14.

The filter unit 10 is disposed in the can body 20, and the longitudinal direction of the filter tube 11 is oriented in the horizontal direction.

The can body 20 in which the filter unit 10 is provided is made of a ceramics such as alumina ceramics, and has a substantially rectangular parallelepiped shape with an upper opening. The can body 20 has a space in which the filter unit 10 can be disposed. The space is defined by the bottom surface and four inner walls. One of the four inner walls The inner wall is opposed to the liquid inlet side end plate 13 and the liquid discharge side end plate 14 of the filter unit 10 in a state in which the filter unit 10 is provided. The inner wall opposed to the liquid discharge side end plate 14 is opened at least at a position corresponding to the opening formed in the liquid discharge side end plate 14.

In order to filter the foreign matter in the molten metal, the molten metal is supplied to the can body in a state where the filter unit 10 is provided in the can body 20. The supplied molten metal penetrates into the inside from the outer surface of the filter tube 11 provided in the filter unit 10. At this time, the foreign matter contained in the molten metal is removed. The molten metal melts into the inside of the filter tube 11 and flows through the filter tube 11 and flows out through the opening portion 12 to the outside. In Fig. 1, the direction of the arrow of the two-dot chain line indicates the flow direction of the molten metal.

Fig. 2 is a schematic view showing an embodiment of an installation device for installing the filter unit 10 in the can body 20. The installation device 30 includes a cross frame member 32a that is spanned between the pillars 31a and 31a in the horizontal direction, a horizontal frame member 32b that is horizontally spanned between the pillars 31b and 31b, and a crane beam 33 that is horizontally mounted on the bridge member 31a. Between the cross members 32a, 32b.

The setting device 30 is roughly divided into four platforms. Specifically, the first stage 1 is located on the outer side of the two pillars 31a and 31a and on the far side of the paper surface in FIG. The fourth stage 4 is located on the outer side of the two pillars 31b and 31b and on the near side of the paper surface in Fig. 2 . Further, the second stage 2 and the third stage 3 are adjacent to each other in a region surrounded by the four pillars 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.

From the first platform 1 to the second platform 2, a pair of tracks 34 that are parallel to each other are laid. A transport shuttle 35 is provided on the rail 34, and the transport shuttle 35 is movable on the rail 34. The transport shuttle 35 is configured to be rotatable in a horizontal plane about a vertical line. The can body 20 is placed on the transport shuttle 35, and the can body 20 is movable between the first stage 1 and the second stage 2.

From the fourth platform 4 to the third platform, a conveying device 36 such as a conveyor is provided. The filter unit 10 is placed on the transport unit 36, and the filter unit 10 is movable between the fourth stage 4 and the third stage 3.

A crane 37 is provided between the second stage 2 and the third stage 3. Crane 37 can be along The crane beam 33 moves in the Y direction in the horizontal plane. At the same time, it is also possible to move in the X direction in the horizontal plane. The crane 37 can in turn be raised and lowered in the vertical direction Z.

At the lower end of the crane 37, a holding device 38 is mounted, which is capable of loading and unloading the filter unit 10 and for arranging the filter unit 10 in the can body 20. The details of the holding device 38 will be described below.

When the method of installing the filter unit 10 using the setting device 30 having the above configuration is described, first, as shown in FIG. 3, the can body 20 in which the filter unit 10 is provided is carried into the first stage 1 and placed in the The first platform 1 is placed on the transport shuttle 35. After the can body 20 is placed on the transport shuttle 35, the transport shuttle 35 moves along the rail 34 to transport the can body 20 to the second stage 2.

The can body 20 that has been transported to the second stage 2 measures the XY coordinates of the inner wall of the can body 20 by the inspection camera 39 provided on the second stage 2, and memorizes the size of the inner wall by a memory mechanism (not shown). And location information. Then, when the inner wall of the four faces of the can body 20 is inclined from the XY direction based on the measurement result of the XY coordinates, the drive shuttle 35 is rotated in a plane around the vertical line by a drive mechanism (not shown) such as a servo motor. The correction is made to make the direction of the inner wall coincide with the XY direction, and the corrected position information is memorized.

After the inspection camera 39 captures the can body 20 that has been transported to the second stage 2, the crane 37 is moved and placed directly above the can body 20 as shown in FIG. At the front end of the crane 37, the holding device 38 described above is mounted. Further, a length measuring sensor B is attached to the front end of the crane 37. Therefore, in this state, the holding device 38 is located above the can body 20, and the holding device 38 can be raised and lowered. From this state, the crane 37 is lowered, and as shown in Fig. 5, the front end of the crane 37 is inserted together with the length measuring sensor B into the can body 20 in a state before the filter unit 10 is disposed. Then, the inside of the can body 20 is scanned by the inserted length measuring sensor B, and the size of the inside of the can body 20 is measured. Further, the position information of the inside of the can body 20 is memorized. The scan result of the inside of the can body 20 obtained by the length measuring sensor B is sent to an arithmetic unit (not shown). In the arithmetic unit, the state in the can body 20 obtained by the scanning is compared with a preset state, and the state in the can body 20 scanned is in a predetermined state. In addition, an order to discharge the can body 20 as a defective product is transmitted. Based on the discharge command, the can body 20 is discharged to the outside of the second stage 2 by a specific device.

The length measuring sensor B also measures the amount of tilt in the vertical direction of the inner wall of the can body 20 by scanning the inside of the can body 20. Then, based on the amount of inclination obtained by the measurement, the amount of inclination in the vertical direction of the end plate of the filter unit 10 provided in the can body 20 is adjusted. In particular, the amount of inclination of the liquid discharge side end plate 14 is made to match the amount of inclination of the inner wall opposite to the liquid discharge side end plate 14. By making the inclination amounts of the two uniform, it is possible to effectively prevent the leakage of the melt. In order to adjust the amount of inclination of the end plate in the vertical direction, for example, the thin plate 40 for tilt adjustment (see FIG. 6) may be attached to the bottom surface of one of the liquid inlet side end plate 13 or the liquid discharge side end plate 14.

A washer 41 (see Fig. 6) is attached to the outer surface of the liquid discharge side end plate 14 of the filter unit 10 together with the mounting of the thin plate for tilt adjustment. The washer 41 is formed of a rectangular annular body and is attached so as to surround all the openings provided on the liquid discharge side end plate 14. The gasket 41 is made of, for example, alumina fiber.

After the measurement of the dimensions and the like in the can body 20 in the second stage 2 is completed, the filter unit 10 is lifted by the loading crane 42 provided on the fourth stage 4 as shown in FIG. The transport device 36 of the platform 4. The gasket 41 described above is attached to the outer surface of the liquid discharge side end plate 14 before being carried into the conveying device 36.

As shown in Fig. 6, after the filter unit 10 is carried into the transport device 36 of the fourth stage 4, the tilting amount of the inner wall of the can body 20 in the second stage 2 described above is at the end of the filter unit 10. A thin plate 40 is mounted on the bottom of the board. Then, the conveying device 36 is actuated to transport the filter unit 10 to the third stage 3.

After the filter unit 10 is transported to the third stage 3, the crane 37 (see FIG. 2) is moved, and as shown in FIG. 7, the holding device 38 is placed above the filter unit 10. This positioning can be performed by visual inspection by an operator. Alternatively, as shown in the figure, the filter unit 10 is photographed by the camera 43 attached to the length measuring sensor B, and the position of the filtering unit 10 captured by the camera 43 is recognized, so that the holding device 38 automatically Move to directly above the retainable filter unit 10 The location.

After the holding device 38 is located directly above the filter unit 10, the crane 37 is lowered to bring the holding device 38 close to the filter unit 10. The lowering of the holding device 38 can be performed by visual inspection by an operator. Alternatively, the distance measurement result obtained by using the length measuring sensor B mounted on the holding device 38 or the length measuring sensor C (not shown) installed separately from the length measuring sensor B may be used. The automatic lifting causes the holding device 38 to descend. In this case, the length measuring sensor B or the length measuring sensor C can measure the distance between the holding device 38 and the filter unit 10. Moreover, the holding device 38 is configured to automatically hold the filter unit 10 based on the distance L between the holding device 38 and the filter unit 10 measured by the length measuring sensor B or the length measuring sensor C. . The measurement of the distance L can be, for example, as shown in Fig. 7, based on the upper surface of the liquid inlet side end plate 13 or the liquid discharge side end plate 14.

After the holding device 38 is lowered to a position where the filter unit 10 can be held, as shown in FIG. 8, the holding cylinder provided in the holding device 38 is protruded. The protruding clamping cylinders 44 are inserted into the openings formed in the respective end plates 13, 14 of the filter unit 10. By this insertion, the filter unit 10 is held by the holding device 38. After the holding is completed, the wedge 45 is detachably attached to the holding device 38. Thereby, the wedge 45 is provided in the can body 20 together with the holding device 38 in a state in which the filter unit 10 is held. The number of the wedges 45 is set to one or two or more. The purpose of use of the wedge 45 will be described below. The mechanism for attaching the wedge 45 to the holding device 38 is not particularly limited. For example, it can be manually mounted by an operator on a third platform, or automatically mounted by a robot.

After the filter unit 10 is held by the holding device 38 in this manner, the crane 37 is raised to lift the filter unit 10. Then, the crane 37 is moved in the Y direction (see FIG. 2) so as to be positioned above the second platform 2. In the second stage 2, the can body 20 is placed by the previous operation, and the filter unit 10 is disposed directly above the can body 20 as shown in FIG. This configuration can be performed by visual inspection by an operator. Alternatively, the size and position information of the can body 20 measured by the operation shown in FIG. 5 described above can be automatically performed.

After the filter unit 10 is placed directly above the can body 20, the crane 37 is lowered to set the filter unit 10 inside the can body 20. The drop of the filter unit 37 can be performed by visual inspection by an operator. Alternatively, as shown in FIG. 10, the inner wall of the can body 20 is scanned by the length measuring sensor B which is lowered together with the filter unit 10, so that the filter unit 10 does not contact the inner wall of the can body 20. The mode automatically adjusts the position and lowers it.

The confirmation that the filter unit 10 has been placed in the bottom of the can body 20 can be performed by visual inspection by an operator. Alternatively, the load of the load cell (not shown) attached to one of the descending cranes may be continuously measured, and the load value of the load cell is automatically below the threshold value to automatically determine that the load has been made.

After confirming that the filter unit 10 has been placed in the bottom of the can body 20, the holding cylinder 44 in the holding device 38 is retracted and released. Then, as shown in FIG. 11, a jack 46 is provided in the can body 20. The jack 46 is inserted between the liquid inlet side end plate 13 in the filter unit 10 and the inner wall 20a of the tank body opposed thereto. The jack 46 is for pressing the liquid discharge side end plate 14 of the filter unit 10 provided in the can body 20 against the inner wall of the can body 20. To achieve this, the jack 46 may include, for example, one or more hydraulic cylinders 47. The jack 46 is provided with a hook portion 48 at its upper portion, and the hook portion 48 is fixed to the liquid inlet side end plate 13 by engaging the hook portion 48 with the upper portion of the liquid inlet side end plate 13.

The jack 46 is placed in the can body 20, and the length measuring sensor A is placed in the can body 20. The length measuring sensor A has a configuration that is detachable from the filter unit 10. The length measuring sensor A is installed at four positions in the vicinity of the liquid discharge side end plate 14 of the filter unit 10. Specifically, it is attached to the upper left and right upper and lower left and right portions in the vicinity of the outer surface of the liquid discharge side end plate 14. Each of the length measuring sensors A is configured to measure the distance from the outer surface of the inner wall 20b of the can body 20 opposite to the liquid discharging side end plate 14 and the outer surface of the liquid discharging side end plate 14. Furthermore, in Fig. 11, the jack 46 and the length measuring sensor A are independent individuals, but instead of this, the jack 46 and the length measuring sensor A are integrally formed, and both are integrated into the can. Within body 20. Further, in Fig. 11 and Fig. 12 described below, the illustration of the holding device 38 and the wedge 45 is omitted.

After the jack 46 and the length measuring sensor A are mounted at a specific position, as shown in FIG. 12, the hydraulic cylinder 47 of the jack 46 is actuated to move the filter unit 10, and the liquid discharge side end plate 14 is pressed against the can body 20. The inner wall 20b. The hydraulic cylinder 47 is actuated by actuating the hydraulic pump 48. In the case where the jack 46 includes two or more hydraulic cylinders 47, it is preferable that each of the hydraulic cylinders 47 can be individually controlled. Thereby, it is easy to make the force which presses the liquid discharge side end plate 14 against the inner wall 20b of the can body 20 equal.

The actuation of hydraulic pump 48 is controlled by control unit 49. The hydraulic cylinder 47 is actuated, and the distance between the outer surface of the liquid discharge side end plate 14 and the inner wall 20b of the can body 20 is gradually shortened. That is, the pressing amount when the filter unit 10 is pressed against the inner wall 20b of the can body 20 by the jack 46 gradually changes. The pressure is measured by monitoring the pressure amount by the length measuring sensor A. The monitoring of the amount of pressure is performed by a control device 49 to which a signal from the length measuring sensor A is connected. Further, after the pressure of the filter unit 10 by the jack 46 reaches a specific pressure difference, the self-control device 49 transmits a signal to the hydraulic pump 48 to stop the operation. The hydraulic pump 48 that receives the signal ceases to act, and the jack 46 maintains the pressure as of now.

In this state, as shown in FIG. 13, the wedge 45 previously attached to the holding device (not shown) is removed from the holding device. The wedge 45 is used to maintain the pressure-receiving state of the filter unit 10 in a state in which the jack 46 is pressed against the inner wall 20b of the can body 20 until a specific amount of pressure is applied. The wedge 45 is made of a ceramic such as alumina.

The wedge 45 is dropped by the self-retaining device and is inserted between the outer surface of the liquid-input side end plate 13 and the inner wall 20a of the can body 20. Since the weight of the wedge 45 is heavy, the wedge 45 is surely inserted between the outer surface of the liquid-input side end plate 13 and the inner wall 20a of the can body 20 by the energy generated by its falling. By this fitting, the state of adhesion between the outer surface of the liquid discharge side end plate 14 of the filter unit 10 via the gasket 41 and the inner wall 20b of the can body 20 is surely maintained, and the leakage of the molten metal is effectively prevented. It is also possible to use a hammer or the like to embed the wedge 45 of the embedded state deeper. In addition, in FIG. 13, the illustration of a hydraulic pump is abbreviate|omitted for convenience of description.

When the wedge 45 is removed from the holding device, it can be manually performed by an operator. Alternatively, for example, the holding device may receive the removal signal sent from the control device 49, and the wedge 45 is automatically removed, and the wedge 45 is automatically inserted into the outer surface of the liquid inlet side end plate 13 of the filter unit 10. Between the inner wall 20a of the can body 20.

After the embedding of the wedge 45 is completed, the pressure of the hydraulic pump 48 is released according to an instruction from the control device 49, and the pressing by the jack 46 is released. Then, the jack 46 and the length measuring sensor A are taken out from the can body 20, and the holding device (not shown) is lifted and retracted above the can body 20. The removal of the jack 46 and the length measuring sensor A can be performed by an operator using a crane or the like, or can be automatically taken out. In this manner, the setting of the filter unit 10 into the can body 20 is completed. Then, the transport shuttle 35 (see FIG. 2) is actuated to move the can body 20 from the second stage 2 to the first stage 1. The can body 20 that has moved to the first stage 1 is lifted by a carry-out crane (not shown) and carried out. Thereafter, the operations described up to now are repeated.

In addition, in FIG. 11 , the jack 46 and the length measuring sensor A are disposed separately from the holding device 38 in the can body 20 , but instead of this, the jack 46 can be detachably mounted on the holding device 38 . The jack 46 is disposed in the can body 20 together with the filter unit 10 held by the holding device 38. Thereby, the setting of the filter unit 10 can be further automated. Alternatively, the length measuring sensor A may be attached to the holding device 38, and when the holding unit 38 holds the filter unit 10, the length measuring sensor A may be attached to the filter unit 10. Thereby, the setting of the filter unit 10 can be further automated.

The insertion of the wedge 45 shown in Fig. 13 utilizes the weight of the wedge 45, but instead of this, an external force is applied to the wedge 45 to actively insert it. For example, as shown in FIG. 14, a winch 51 is provided in advance directly above the wedge 45, and the weight 51 is lifted and lowered by the winch 51. When the weight 50 is raised, the wire attached to the weight 50 is wound around the winch 51 and rolled up. When the weight 50 is lowered, the rotating shaft of the winch 51 is placed in a state of no load, 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 liquid-input side end plate 13 and the inner wall 20a of the can body 20 by the energy of the free-falling weight 50 colliding with the wedge 45.

The degree of insertion of the wedge 45 can be monitored, for example, as shown in FIG. 15, by the length measuring sensor 52 disposed below the winch 51. The length measuring sensor 52 can emit laser light and measure the distance from the upper surface of the weight 50. If the signal from the length measuring sensor 52 is wound up and the free fall 50 is processed, a graph such as that shown in Fig. 16 can be obtained. In the graph shown in the figure, when the difference between the value of the position of the vertical axis and the value of the previous position is smaller than the set value, it can be judged that the wedge 45 has been inserted to a specific depth.

The degree of insertion of the wedge 45 can also be measured by using the length measuring sensor 52 shown in Fig. 15 by using the vibration sensor 53 shown in Fig. 17. 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 the vibration generated when the weight 50 falls freely and collides with the wedge 45. If the signal from the vibration sensor 53 is wound up and the free fall 50 is processed, a graph such as that shown in Fig. 18 can be obtained. In the graph shown in the figure, when the value of the amplitude of the vibration of the vertical axis satisfies the set value or the duration of the vibration of the horizontal axis satisfies the set value, it can be judged that the wedge 45 has been inserted to a specific depth.

The insertion of the wedge 45 can also be performed by the pressing device 54 as shown in Fig. 19 instead of using the free fall of the weight 50 shown in Fig. 14. As the pressing 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 pressing device 54 such that the forward and backward directions of the piston 56 coincide with the vertical direction. The piston 56 is disposed in such a manner that its lower end is aligned with the upper end of the wedge 45. Further, by driving the pressing device 54, the piston 56 is lowered toward the wedge 45, thereby pressing the wedge 45. The self-pressing device 54 transmits a signal corresponding to the press-in pressure (load) and/or the press-in position when the piston 56 presses the wedge 45 to a control device (not shown). A graph such as that shown in Fig. 20 is obtained by processing the signal in a control device that receives the signals. In the graph shown in the figure, when the value of the press-in position on the vertical axis satisfies the set value, for example, it can be judged that the wedge 45 has been inserted to a specific depth. Alternatively, when the value of the pressing pressure (load) on the vertical axis satisfies the set value, it can be judged that the wedge 45 has been inserted to a specific depth.
