Description

  The present invention relates to a drilling device, a recycled resin, and a resin product.

  In April 2001, the Home Appliance Recycling Law was enacted, and television receivers, refrigerators, air conditioners and washing machines were actively recycled. These devices are dismantled mainly at home appliance recycling factories. In general dismantling methods for these devices, first, members that are in the processing form of each recycling plant are separated and collected by manual disassembly. Next, the member that has not been collected by manual dismantling is crushed by a crusher until it reaches a size of about several tens of mm. By performing this crushing step, the volume of the member is reduced and the parts that have been joined are separated. Further, the crushed material is sorted into ferrous, non-ferrous or shredder dust using a sorting device such as a wind sorting device, a magnetic sorting device or an eddy current sorting device.

  Parts collected by manual dismantling are required by law and must be collected reliably, those that do not want to be shredded for sale, and those that pass through each device, such as a crusher or sorting device, will cause the device to malfunction. Or those that require frequent maintenance.

  Fluids such as liquids and gases are among those that are manually collected for the purpose of reducing the frequency of maintenance of each device. Some fluids cause a chemical reaction with members of a crusher or a sorting device, causing corrosion, and increasing the frequency of maintenance of each device. For example, in a washing machine, salt water enclosed in a balancer can be cited as a fluid that adversely affects each device such as a crusher and a sorting device.

  FIG. 33 shows a sectional view of a general structure of a washing machine. The washing machine includes a housing 1 and an upper lid 2. A water tank 6 is disposed inside the housing 1. The water tank 6 is a container having an open top. Water for washing is stored in the water tank 6. The water tank 6 is fixed to the upper lid 2 or the housing 1 by the hanging rod 3. A dewatering tank 7 is arranged inside the water tank 6. The dehydration tank 7 is a container having an open top. The dewatering tank 7 rotates to dehydrate clothes and the like. The housing 1 and the water tank 6 are often made of resin, and the dehydration tank 7 is often made of metal.

  On the bottom surface of the water tank 6, a motor 4 and a reduction gear unit 5 for rotating a dehydrating tank 7 and a rotating blade (pulsator) (not shown) arranged inside the dehydrating tank 7 are arranged. The dewatering tank 7 or a pulsator (not shown) is formed to rotate when the rotational movement of the motor 4 is transmitted to the reduction gear unit 5 and the shaft that penetrates the water tank 6 rotates.

  A balancer 8 is disposed above the dewatering tank 7 so that the dewatering tank 7 rotates smoothly. The balancer 8 is formed in an annular shape, and a liquid is sealed inside. The balancer 8 is often made of resin. By arranging the balancer 8 in the dewatering tank 7, eccentricity and vibration of the dewatering tank during dehydration are suppressed. In the liquid sealed in the balancer, a further effect can be obtained by using a liquid having a large specific gravity. As this liquid, a sodium chloride aqueous solution or a calcium chloride aqueous solution is used in most washing machines from the viewpoint of stability of the substance and economy. In the present invention, the liquid sealed in the balancer is referred to as “salt water”.

  FIG. 34 shows a perspective view of one embodiment of the balancer. A balancer 8 a is disposed on the top of the dehydration tank 7. The balancer 8 a is formed in an annular shape along the outer edge of the dewatering tank 7. Plate-shaped ribs 9 are arranged on the balancer 8a. A plurality of ribs 9 are arranged such that the main surface is parallel to the radial direction. Each cell partitioned by the ribs 9 is formed to communicate with each other. That is, the rib 9 is formed so as not to seal each cell. The formation of the ribs 9 increases the effect of preventing the fluid from moving in the circumferential direction and suppressing eccentricity during dehydration.

  FIG. 35 shows a perspective view of another form of the balancer. The balancer 8b includes a partition plate 10 disposed so that the main surface is substantially parallel to the circumferential direction. In the balancer 8b, two partition plates 10 are arranged, and three layers of cells extending in the circumferential direction are formed. Some balancers have a two-layer structure. In such a balancer in which multilayer cells are formed in the circumferential direction, the inside of each cell is sealed. That is, the partition plate 10 is disposed so that there is no movement of liquid between adjacent cells.

  Balancer salt water is collected by manual dismantling. For example, when the balancer is crushed by a crusher, the balancer is crushed and the salt water enclosed inside is scattered. The salt water adheres to each crushed member in addition to the crusher. As a result, corrosion by salt water is promoted everywhere such as a crusher, a transporter that connects each device, or a sorting device. Corrosion of each device causes many problems in operating each device, and is not preferable for safety. This requires frequent maintenance of the equipment. Furthermore, when salt water adheres to each crushed member, the sorting accuracy in the step of sorting the materials is reduced.

  Thus, it is not preferable to crush the balancer with salt water in it, and it is preferable to recover the salt water before crushing. For this reason, in many home appliance recycling plants, salt water is collected by manual dismantling before crushing.

  As a salt water recovery method performed in a recycling plant, it is common to drain the salt water enclosed by a mechanical method such as making a hole in the balancer or cutting the balancer. For example, a method of making a hole in the balancer with a tool such as an electric drill, or a method of cutting the balancer while attached to the washing machine main body with a cutter arranged in parallel on the disassembly work table (for example, JP-A-2001-2001). 1988858 publication).

Alternatively, there is a method of destroying the balancer by compressing (pressing) a washing machine or a water tank in a state where the salt water is sealed after allowing the salt water to scatter.
JP 2001-198858 A

  In the method of making a hole in the balancer with the above-described tool such as an electric drill, holes are made in a plurality of locations of the balancer with an air drill or an electric drill. In this method, drilling can be performed with a lightweight tool. However, depending on the balancer's internal structure, it is necessary to change the drilling position and the number of holes to be drilled. There was a problem of pouring out. As a result, there is a problem that the work may be completed while the salt water remains.

  For example, in the multilayer balancer having a plurality of cells in the circumferential direction shown in FIG. 35, since salt water is sealed in each cell, a hole for discharging the salt water is formed in each cell. There is a need. On the other hand, in the balancer in which many cells are formed in the radial direction shown in FIG. 34, since each cell communicates, it is not necessary to make holes in all the cells. As described above, the position and the number of holes to be drilled must be determined depending on the type of balancer, and there is a problem that an appropriate hole cannot be drilled unless experience is gained.

  Moreover, since the diameter φ of the hole that can be opened with a lightweight tool is as small as about 10 mm or more and 15 mm or less, there is a problem that the discharge time of salt water becomes long. For this reason, it is common to shorten the time for discharging salt water by opening an air hole in addition to the discharge hole. That is, in a single-layer balancer in which cells communicate with each other as shown in FIG. 34, it is necessary to make two holes. For a three-layer balancer in which the cells are sealed as shown in FIG. 35, it is necessary to make six holes. In order to make many holes in this way while taking into account the positions where holes are to be drilled, there is a problem that it takes time and workability is poor.

  Moreover, when making a hole in the balancer, there has been a problem that the wrist of the operator is often damaged by the resistance (reaction force) received from the drill. In particular, when using an impact-type drill frequently used in hand dismantling, there is a problem that a large impact force is transmitted to the wrist and the wrist is damaged.

  In the method of cutting the balancer while attached to the washing machine main body with the cutter arranged side by side in the above disassembly work table, when all disassembly is performed with the washing machine placed on the work table Is effective. However, in order to place a large and heavy workpiece such as a washing machine on such a high work table, a moving device such as a table lift is provided at each work station, and an operator places it on the work table each time. It is necessary to place the washing machine directly on each work table by a large transport system. However, when the worker puts it every time, there is a problem that work efficiency deteriorates with movement. In addition, when loading by a large transport system, there is only a small part of the recycling plant provided with such a transport system, and there is a problem that smooth introduction to a general home appliance recycling plant is impossible.

  FIG. 36 is an explanatory diagram of a working method when dismantling the washing machine in the home appliance recycling plant. Referring to FIGS. 33 and 36, first, water tank 6 is taken out from casing 1 with surrounding parts such as reduction gear unit 5 attached. The water tank 6 is placed on the floor in an inverted state.

  On the lower side (bottom surface) when the water tank 6 is disposed in the washing machine, members having irregularities such as the motor 4 and the reduction gear unit 5 are disposed. On the other hand, on the upper side when the water tank 6 is arranged in the washing machine, the end of the water tank 6 or the end of the balancer 8 is included in one plane. Since the water tank 6 taken out from the housing 1 is stable when placed on the floor in an upside down state, it is generally placed on the floor in an upside down state.

  If you want to cut the balancer manually using a cutter, turn the tank upside down and hold it so that it is easy to cut, or lift the washing machine and place it sideways on the workbench. I need it. Further, after fixing by some means, it is necessary to find out the cutting portion of the balancer and align the cutter. Moreover, in order to improve the removal efficiency of salt water, after cutting is completed, it is necessary to turn the water tank upside down again or to lower it from the work table to the floor.

  The water tank including the dewatering tank and the reduction gear unit has a weight of about 10 kg to 20 kg, so that there is a problem that the burden on the operator is large when the water tank is lifted or turned upside down. Furthermore, when cutting with a cutter, there is a problem that it takes time to position the cutter and the work efficiency is poor.

  If the dewatering tank is taken out from the water tank in advance or only the balancer is taken out from the dewatering tank in advance, the workpiece to be cut becomes light, and the burden of lifting and flipping up and down is reduced. However, it is the same as described above that it is necessary to identify and fix the cutting portion of the balancer to be cut or to align the cutter, and there is a problem that workability is poor.

  In particular, the salt water recovery operation is often performed collectively in a specific waterproof area or rust prevention area created in an area where manual dismantling is performed in order to prevent the salt water from adhering to each member. . In such a case, it is preferable that the salt water recovery operation is continuously processed as one step of the flow operation. However, as described above, by placing a water tank or the like on the work table or turning it upside down as described above. However, there has been a problem that the processing speed of the recovery operation of the salt water becomes slow and the flow operation is difficult.

  In the method of destroying the balancer by compressing while the balancer is attached, the balancer can be destroyed over the entire circumferential direction, so that salt water remains inside the balancer compared to other methods. Few. However, in addition to the problem of corrosion due to the scattering of the salt water described above, there is a problem in that the water tank or the dehydration tank is deformed into a complicated shape by compression, and the component parts bite each other in many places. there were. For example, when the purpose is to collect plastics for recycling, there is a problem that it is extremely difficult to collect only plastic members such as water tanks from the state where the components are engaged with each other.

  In addition, since plastic and metal debris are scattered in large quantities together with salt water at the same time as the destruction due to compression, there is a problem that is dangerous for the surrounding people. Moreover, since the press machine which performs such a compression is intended for the main body of the washing machine, the water tank or the dewatering tank, there is a problem that a large press machine and a large place are required. In addition, there is a problem that a large amount of money is required.

  In addition to dismantling the washing machine, for example, a drum can in which a fluid waste is sealed or a housing portion in which a dangerous liquid is housed, a hole is made to flow out and the fluid can be collected to collect the fluid. It may be preferable.

  FIG. 5 is an explanatory diagram of the notch blade 15. Fig.5 (a) is a side view of the notch blade 15, (b) is a top view, (c) is arrow sectional drawing regarding the VC-VC line in (a).

  As shown in FIG.5 (c), the cross-sectional shape of the trunk | drum 33 and the front-end | tip part 34 of the notch blade 15 is formed so that it may become a mountain shape. The notch blade 15 is disposed such that the top of the mountain shape having a cross-sectional shape is on the upper side. In the present embodiment, the height h11 of the notch blade 15 is 32 mm, the blade edge angle θ11 is 30 °, the thickness t11 of the notch blade is 7 mm, the blade opening angle θ12 in the cross-sectional shape is 60 °, and the length l11 is It is formed so as to be sufficiently longer than the thickness of the balancer. The material of the notch blade 15 is formed using stainless steel SUS440 from the viewpoint of wear resistance and corrosion resistance.

  FIG. 6 shows an explanatory view of the position of the notch blade 15 in the present embodiment. The average thickness t21 of the balancer 8 employed in the washing machine is 40 mm. When the balancer 8 is disposed in contact with the mounting table 12 and the support portion 14, the position where the tip of the notch blade 15 contacts the balancer is in the direction perpendicular to the mounting surface of the mounting table 12. The distance d21 from the mounting surface is about 11 mm. The notch blade 15 is disposed so as to contact the lower part of the inner side surface of the balancer 8 when the balancer 8 having a thickness t21 of 40 mm is disposed.

  With reference to FIG. 1, in this Embodiment, the support structure is employ | adopted so that the force of directions other than a moving direction may not be added with respect to the shaft 21. FIG. Specifically, a guide rod fixed to the notch blade is disposed along the direction of the arrow 101 in which the notch blade 15 moves, and the guide rod is supported by a bearing (not shown). A bush may be arranged instead of the bearing for supporting the guide rod.

  Further, in the connection between the notch blade 15 and the air cylinder 16, an edge cutting structure in which the connection is not completely fixed is employed (not shown). In this embodiment, connection by a floating joint is used, but this may be pin connection by a rod end. Moreover, it is good also as a surface pressure structure as another edge cutting method. For example, when the notch blade 15 is moved toward the balancer 8, the notch blade 15 is moved by being subjected to surface pressure by a cylinder rod not connected to the notch blade 15, and when retracted from the balancer 8, a spring is used. The cutout blade 15 may be formed so as to return to the original starting point by elastic means such as.

  The drilling device in the present embodiment includes automatic operation control means for automatically drilling holes. The automatic operation control means includes a foot pedal as a switch. In the present embodiment, an automatic return contact type switch is employed as the foot pedal. The automatic control operation means is formed so that the notch blade moves and part of the balancer is cut off while the operator continues to step on the foot pedal. The foot pedal in the present embodiment is disposed at a position about 1.5 meters away from the apparatus main body so that the operator is not damaged by the notch blade.

  With reference to FIG. 1, in the automatic operation, the facing portion 13 moves toward the support portion 14, and the workpiece is sandwiched between the support portion 14 and the facing portion 13. Next, the air cylinder 16 is driven, and the notch blade 15 advances toward the balancer 8 to cut off a part of the balancer 8. Next, when the air cylinder 16 is driven, the notch blade 15 is retracted from the balancer 8 and returned to the starting point. Further, the facing portion 13 is formed so as to retreat from the workpiece and return to the starting point.

  The drilling device in the present embodiment includes a safety control device as a safety device. Referring to FIG. 1, the safety control device in the present embodiment includes an optical sensor for detecting whether or not an object to be processed is arranged on mounting table 12. The safety control device is formed such that when a workpiece is not yet arranged on the mounting table 12 by the optical sensor, each member such as a notch blade is not moved by disabling the foot pedal.

  The safety control device includes a proximity sensor disposed at the end of the air cylinder so that the position of the notch blade can be determined. When the workpiece is removed from the fixing means during the automatic operation, the shaft 21 of the air cylinder 16 is completely extended and reaches the stroke end. At this time, the proximity sensor reacts to automatically return the notch blade to the starting point.

  In addition, the safety control device is configured to forcibly retract the notch blade 15 to return to the original starting point when detecting that the workpiece is detached from the mounting table 12 by the optical sensor during automatic operation. Yes. At this time, the opposing portion 13 is also formed so as to move away from the support portion 14 and return to the original starting position. Further, when the signal from the foot pedal disappears, the notch blade 15 and the facing portion 13 are retracted to return to the original starting point.

  In FIG. 15, the side view of the 2nd drilling apparatus in this Embodiment is shown. In the second drilling device, the mounting table 12 and the support portion 14 are integrally formed. The mounting surface of the mounting table 12 and the main surface of the support portion 14 are formed to be substantially vertical. The planar shape of the mounting table 12 is formed to be substantially rectangular. The support portion 14 is formed so that the main surface is curved, as in the first drilling device. Similar to the first drilling device, an opening is formed in the mounting table 12 and the support portion 14 so that the notch blade 15 can be inserted therethrough.

  The recycled resin in the present embodiment is recovered by removing the internal salt water from the balancer formed of the resin using the drilling device in the present embodiment. In addition, the resin product in the present embodiment is formed using the above recycled resin.

(Action / Effect)
The drilling device in the present embodiment is a device for making a hole in a balancer of a washing machine and taking out salt water inside. First, with reference to FIG. 7 and FIG. 8, an object to be processed of the drilling device in the present embodiment will be described.

  FIG. 7 is a perspective view of the dewatering tank unit 17. The dewatering tank unit 17 includes a dewatering tank 7 and a balancer 8. The dehydration tank 7 is formed in a bottomed cylindrical shape. The balancer 8 is formed in an annular shape. The balancer 8 is fixed to the dewatering tank 7 along the opening of the dewatering tank 7. In the dewatering tank unit 17, a flange or a pulsator (rotary blade) (not shown) may be disposed inside the dewatering tank 7.

  In the present invention, among the members separated and taken out from the water tub of the washing machine, a member in which at least the dewatering tank and the balancer are integrated is referred to as a “dewatering tank unit”. In the present invention, of the outer surfaces of the dewatering tank unit, the outer surface that becomes the upper end when attached to the washing machine is referred to as the “top surface of the dewatering tank unit”. The top surface of the dewatering tank unit may be a flat surface or a curved surface. In FIG. 7, the top surface 36 of the dewatering tank unit is one surface of the balancer 8 and is formed in a planar shape.

  FIG. 8 is a perspective view of the water tank unit 18. The water tank unit 18 includes a water tank 6 and a dewatering tank unit 17. In many cases, the bottom of the water tank 6 is provided with a reduction gear unit for rotating the internal dewatering tank 7, a motor (not shown), and the like. In the present invention, a member taken out from the casing of the washing machine and including at least a water tank and a dewatering tank unit is referred to as a “water tank unit”. Moreover, in this invention, the outer surface which becomes an upper end when it attaches to a washing machine among the outer surfaces of a dehydration tank unit is called "the top surface of a water tank unit." The top surface of the water tank unit may be a flat surface or a curved surface. In FIG. 8, the top surface 37 of the water tank unit is the end of the opening of the water tank 6, and is formed in a curved surface shape (not shown).

  As an object to be processed in the present embodiment, in addition to the above-described dehydration tank unit and water tank unit, a balancer alone in which only the balancer is removed from the dehydration tank unit can be cited.

  First, a case where the object to be processed is a dehydration tank unit will be described as an example. As shown in FIG. 7, parts are rarely arranged on the top surface of the dewatering tank unit 17 and are often included in one plane. On the other hand, a shaft for driving the internal pulsator is often disposed on the bottom surface of the dewatering tank unit 17. For this reason, when it is placed on the floor, the balancer is placed on the lower side. That is, the dewatering tank unit 17 is stored upside down by being inverted upside down so that the top surface of the dehydration tank unit 17 is on the lower side.

  In FIG. 9, the side view at the time of putting a to-be-processed object on a drilling apparatus, or taking it down is shown. The worker 91 lifts the dewatering tank unit 17 with the balancer 8 facing downward and places it on the mounting table 12 of the drilling device. The dewatering tank unit 17 is arranged in a region sandwiched between the support portion 14 and the facing portion 13 on the placement surface of the placement table 12. Since the mounting surface of the mounting table 12 is formed so as to be inclined, when the dehydrating tank unit 17 is placed on the mounting table 12, the dehydrating tank unit 17 comes into contact with the support portion 14.

  When the placement of the dewatering tank unit 17 is completed, the worker 91 steps on the foot pedal 19 to start the automatic operation by the automatic operation control device. The worker 91 keeps stepping on the foot pedal while the automatic operation is performed.

  First, the facing portion 13 moves toward the support portion 14 by an air cylinder (not shown). The dewatering tank unit 17 is sandwiched and fixed between the facing portion 13 and the support portion 14. As the fixing means, the support part and the facing part are formed so as to sandwich the object to be processed, or the fixing means is formed to press and fix the object to be processed from the outside. The structure of the fixing means can be simplified. Furthermore, the movable state of the facing portion can be directly observed, and safety is improved. Further, it is not necessary to arrange a fixing means around the notch blade 15, and the maintenance workability is improved.

  In the present embodiment, the support portion 14 and the facing portion 13 are formed in a circular arc shape at a portion in contact with the object to be processed. By adopting this configuration, the workpiece can be automatically positioned at the same time as the workpiece is sandwiched between the support portion and the facing portion. The operator only needs to perform rough alignment when placing the workpiece on the mounting table, and fine adjustment is not necessary. For this reason, work efficiency improves. The support part and the opposing part are not limited to a plate-like member having a circular cross-sectional shape. For example, the opposing part may have two flat plates arranged in a letter C shape.

  In the present embodiment, the support portion and the facing portion are formed in an arc shape having a curvature radius of 300 mm. By adopting this configuration, the punching device in the present embodiment can be used for almost all washing machines.

  In the present embodiment, the air cylinder that moves the opposing portion employs a thrust force of 5 kgf, but is not limited to this configuration, and the opposing portion is pressed by elastic means such as a spring. It doesn't matter. Further, it is not necessary to form the facing portion 13 in particular, and the object to be processed may be directly pressed by hand.

  Next, referring to FIG. 1 and FIG. 2, when the air cylinder 16 is driven, the shaft 21 moves and the notch blade 15 advances toward the balancer 8. The notch blade 15 is inserted through the opening 31 formed in the mounting table 12 and the opening 32 formed in the support part 14 while cutting the balancer 8.

  FIG. 10 is an explanatory diagram when a part of the balancer is removed. Since the mounting table is inclined, the dewatering tank unit 17 is also inclined. By adopting this configuration, the air cylinder 16 can be arranged on the lower side of the mounting table, and the notch blade can be brought into contact with the inner surface of the balancer 8. As a result, the apparatus can be reduced in size.

  Referring to FIG. 10, when the air cylinder 16 is driven, the shaft 21 moves in parallel, and the notch blade 15 advances toward the balancer 8. The notch blade 15 is inserted into the lower part of the inner surface of the balancer 8. Further, when the notch blade advances, a part of the balancer is removed and a hole is made in the balancer.

  FIG. 11 shows a perspective view of the dewatering tank unit 17 with a part of the balancer 8 cut out. The hole 41 is formed along the shape of the notch blade 15 when viewed from the front. The hole 41 is formed so as to penetrate from the inner surface to the outer surface of the balancer 8.

  In the present embodiment, part of the balancer 8 is removed so as to include the three surfaces of the balancer 8, that is, the inner surface, the top surface, and the outer surface. By forming this hole, the opening area of the hole can be increased, and the liquid in the container can be efficiently discharged. For example, a hole having a large opening area can be formed as compared with a case where a hole is made on one surface of the balancer by a hand drill. In this embodiment, excision is performed so as to include three surfaces of the outer surface of the accommodating portion. However, the present invention is not particularly limited to this shape, and includes two surfaces of the balancer inner surface and the top surface. It may be excised. By adopting this configuration, a hole having a large opening area can be formed.

  FIG. 12 shows a perspective view when a hole is drilled in the balancer 8a in which a partition plate is formed along the circumferential direction using the drilling device in the present embodiment. The hole 41 is formed so as to penetrate through the entire thickness direction of the balancer. By adopting this configuration, in the balancer, even if a plurality of layers in the circumferential direction are formed inside, the openings can be surely formed in each layer by one operation, and the internal fluid Can be discharged. Moreover, the hole which has a wide opening area can be made by forming a hole over the whole thickness direction of a balancer. Furthermore, salt water can be discharged reliably regardless of the skill level of the operator and the type of balancer.

  Referring to FIG. 1, internal salt water flows downward from the hole of balancer 8 formed by notch blade 15. The cut-off portion that has been cut off flows below the base member 11 together with the salt water that flows down. Since the mounting table 12 is inclined and a hole is formed in the lowest part of the balancer 8, the salt water inside the balancer 8 can be collected in the hole by gravity, and the salt water inside the balancer 8 can be efficiently collected. Can be discharged.

  The discharged salt water flows down to the base member 11, gathers on the side where the mesh member 28 is arranged along the gradient of the base member 11, and falls to the floor surface through the mesh member 28. By passing the salt water through the mesh member, notch scraps and cut-off portions can be collected by the mesh member, and fluid and solids such as notch scraps can be easily separated. In the present embodiment, the base member is disposed below the mounting table, and the mesh member is disposed in the salt water flow path. By adopting this configuration, it is possible to efficiently recover notched scraps and cut-off portions.

  The notch blade 15 advances in the direction in which the exposed portion of the shaft 21 extends even after the part of the balancer 8 is cut off, and the sensor operates when the stroke end of the air cylinder 16 is reached and the original starting position. Return to. Moreover, the opposing part 13 retracts | saves to the opposite side to the side which goes to the support part 14, returns to the position of a starting point, and an automatic driving | operation is complete | finished.

  Referring to FIG. 9, when drilling of balancer 8 is completed, dewatering tank unit 17 is lowered from the drilling device. When the dewatering tank unit 17 is lowered, the balancer 8 can be lowered on the floor or the like with the balancer 8 facing downward. Thus, the worker 91 lifts the dewatering tank unit 17 and performs payout.

  In the above description, the case where the dehydration tank unit is used as the object to be processed has been described. However, the same procedure can be performed when drilling a single balancer.

  The drilling device according to the present invention does not require complicated operations such as positioning and drilling of an object to be processed, and can be reliably performed by a simple operation of lifting the object to be processed and placing it on the drilling device and then stepping on the pedal. Drilling can be performed. For example, the conventional manual drilling of the balancer takes about 20 seconds, but using the drilling apparatus in the present embodiment, the drilling could be performed in about 4 seconds. Furthermore, the drilling apparatus based on this invention does not have a complicated mechanism, but can provide the drilling apparatus with a simple structure.

  In this Embodiment, the destruction part is arrange | positioned under the mounting base, and the destruction part is formed so that it may contact an accommodating part through the opening part formed in the mounting base. By adopting this configuration, the workpiece can be placed on or lowered from the drilling device while the container is in the lower state with respect to the workpiece to be stored with the container in the lower state. Can be reduced. In addition, the drilling time is shortened and the working efficiency is improved.

  The drilling device in the present embodiment is formed so that the moving direction of the destruction part by the moving means and the mounting surface of the mounting table are inclined. By adopting this configuration, it is possible to form the breaking portion and the moving means for moving the breaking portion on the lower side of the mounting table, and it is possible to reduce the size of the apparatus.

  In the present embodiment, the destruction portion is disposed below the placement surface of the mounting table, and at least a part of the destruction portion is exposed above the placement table when the destruction portion is operated. In the drilling device in the present embodiment, the destruction part, the moving means, and the mounting table are three-dimensionally arranged. Although the destruction part and the moving means can be arranged in a plane on the upper surface of the mounting table, the hole punching apparatus can be reduced in size by providing a three-dimensional arrangement as in this embodiment. It is also possible to place workpieces of various sizes on the mounting table.

  Further, in the present embodiment, a destruction part for excising a part of the accommodation part is included, and the destruction part and the accommodation part are in contact with each other so that a part of the accommodation part including the outer peripheral surface is removed from the accommodation part. Is formed. By adopting this configuration, a hole having a large opening area can be formed in the accommodating portion, and the fluid can be efficiently taken out from the accommodating portion.

  Further, in the present embodiment, the mounting table is disposed so as to be inclined, the support unit is disposed so as to face the lower end of the mounting table, and the notch blade advances toward the support unit. Is formed. By adopting this configuration, the inside of the region supported by the mounting table and the support portion can be excised and stable drilling can be performed. That is, since a hole is formed at a position close to the part where the workpiece is supported, stable drilling can be performed.

  The air cylinder 16 in the present embodiment is formed so that the notch blade 15 can be pushed out with a thrust of 300 kgf. The drive part of the notch blade as the moving means is not particularly limited to the air cylinder, and may be, for example, an electric motor or a hydraulic cylinder.

  It is preferable that the moving means in the balancer drilling device has a thrust of at least 200 kgf or more, preferably 300 kgf or more and 900 kgf or less. A small and inexpensive air cylinder is preferable for this level of thrust. Further, since a general factory is equipped with a compressed air pipe, it is not necessary to prepare an air compressor separately, and the drilling device can be reduced in size, weight, and cost.

  In addition to the balancer drilling device, for example, when the object to be processed is made of metal and the notch blade requires a larger thrust, the drive unit of the moving means is preferably a hydraulic cylinder. By adopting this configuration, a large thrust of the notch blade can be easily generated.

  In the present embodiment, the accommodating portion is fixed, and the breaking portion is moved as the moving means toward the accommodating portion. However, the present invention is not limited to this mode. For example, the breaking portion is fixed and broken. The housing part may be formed so as to move toward the part.

  Moreover, although the destruction part in this Embodiment is formed so that a part of accommodating part may be excised, it is not restricted to this form in particular, You may be formed so that a part of accommodating part may be perforated. Absent.

  In the present embodiment, a cutting means for cutting out a part of the housing part is formed. However, the cutting means is not particularly limited to this form. It may be a cutting means for cutting a part or a punching means for punching a part of the housing part. Specifically, the destruction part may be a rod or needle, a cone rotating in the axial direction, a bar-shaped file rotating in the axial direction, or the like. Alternatively, the breaking portion may be a cutter that is driven by hydraulic pressure so as to cut a part including the outer peripheral surface of the housing portion from the housing portion. That is, the cutter is not limited to only cutting, but is limited to cutting the accommodating portion so as to have a width.

  In the present embodiment, when the cutout blade 15 is retracted (starting position of the cutout blade 15), the cutout blade 15 is formed so as to be disposed below the mounting table 12. The present invention is not limited, and even when the cutout blade 15 is retracted, the cutout blade 15 may be formed so as to be partially exposed from the upper surface of the mounting table 12. That is, at least a part of the notch blade 15 may always protrude from the mounting table. By adopting this configuration, the stroke of the air cylinder 16 can be reduced, and the apparatus can be downsized.

  In the present embodiment, the notch blade is formed in contact with the lower portion of the fixed housing portion. By adopting this configuration, a stable excision can be performed while forming a large hole including an end surface in the lower part of the container.

  In the present embodiment, one hole is formed in the balancer as the accommodating portion. However, the present invention is not limited to this configuration, and a hole may be formed at another position of the accommodating portion. For example, a plurality of fracture portions may be arranged so that two holes are formed in parallel.

  Alternatively, in order to reduce the discharge time of the fluid from the hole, for example, an air hole forming unit that forms an air hole on the opposite side of the formed hole in the radial direction may be formed. For example, a drill that forms an air hole may be disposed in the facing portion for fixing the object to be processed. By adopting this configuration, the fluid in the stored item can be discharged more quickly. As a result of investigating the saltwater discharge time in the balancer of the washing machine, the amount of saltwater discharged immediately after the notch blade was retracted was increased by forming an air hole on the side opposite to the hole for draining the saltwater. By forming the air hole, it was possible to shorten the time required from the withdrawal of the notch blade until the salt water was completely discharged by about 5 seconds.

  Many balancers of washing machines have a complicated internal structure as shown in FIGS. 34 and 35. For a balancer having a structure in which it is difficult to completely discharge salt water by simply drilling a hole in the balancer using the drilling device according to the present invention, after drilling a hole using this device, another work place It is preferable to drain the water by inclining at. Alternatively, it is preferable that the fluid remaining inside the housing portion is completely discharged by an operator tilting or moving the workpiece.

  Referring to FIGS. 4 and 5, the notch blade in the present embodiment is formed so that the tip is sharp. If the cutting edge angle θ11 of the tip end portion 34 is small, the cutting edge has a sharp cutting edge, so that the thrust of the cylinder for driving the cutting edge can be reduced, and the size of the cylinder can be reduced. However, by reducing the cutting edge angle θ11, the length in the longitudinal direction of the tip end portion 34 is increased and the stroke of the cylinder is also increased, so that the cylinder is enlarged in the longitudinal direction.

  On the contrary, when the blade edge angle θ11 is increased, the thrust required for the cylinder is increased, so that the diameter of the cylinder is increased. When the cylinder for driving the notch blade is arranged on the lower side of the mounting table as in the drilling device in the present embodiment, the gradient of the mounting table increases as the diameter of the cylinder increases, and the notch blade Proper drilling is difficult without contacting the balancer at the proper angle.

  As a result of considering the thrust of the notch blade and the configuration of the apparatus, in the balancer drilling device of the washing machine, the blade edge angle θ11 is 30 ° and the blade thickness t11 is 7 mm, as in the notch blade in the present embodiment. By setting the opening angle θ12 to 60 ° and the blade height h11 to 32 mm, the cylinder diameter φ can be set to about 120 mm, and an optimum apparatus configuration can be obtained.

  In the present embodiment, the notch blade is made of stainless steel, but is not limited to this form. In addition to stainless steel, in consideration of wear resistance and corrosion resistance, resistance to resistance such as Hastelloy (registered trademark) is used. It is preferable to use a Ni—Mo alloy having corrosive properties.

  Or as a material of a notch blade, you may employ | adopt spring steel with high hardness. By adopting this configuration, an inexpensive notch blade can be provided. Since spring steel is inferior in corrosion resistance compared to stainless steel and the like, rust is generated on the surface of the notch blade. However, it can be used while being polished by friction with a resin or the like at the time of the notch. When the notch blade is formed of spring steel, it is preferable to perform inspection and replacement at an appropriate frequency in order to prevent the notch performance of the notch blade from being deteriorated.

  Further, in the present embodiment, since salt water flows out as the fluid of the contained material, the mounting table, the base member, and the support columns that support these are also formed of a material having corrosion resistance such as stainless steel. It is preferable.

  The drilling device in the present embodiment includes an air blow nozzle that injects air along the direction in which the fluid flows. By adopting this configuration, salt water, notch scraps, and the like that have fallen on the base member can be washed away along the gradient of the base member, and salt water, notch scraps, and the like can be effectively recovered. Moreover, in this Embodiment, since air is injected also with respect to a notch blade, the salt water adhering to a notch blade can be removed, and the rust etc. of a notch blade can be suppressed.

  When air blowing is performed, it is preferable to use the exhaust of an opposing cylinder for driving the opposing part or an air cylinder for driving a notch blade. By adopting this configuration, the configuration for performing the air blow can be simplified.

  Next, the case where a to-be-processed object is a water tank unit is demonstrated. FIG. 13: is a side view when a water tank unit is arrange | positioned to a drilling apparatus as a to-be-processed object. In the water tank unit 18, the water tank 6 is disposed around the dehydration tank unit 17. The opening on the top surface of the water tank 6 is formed to be larger than the opening on the top surface of the dewatering tank unit 17. Further, the top surface of the dewatering tank unit 17 is often formed so as to be inside (lower) than the top surface of the water tank 6.

  In the present embodiment, the width w1 (see FIG. 2) of the mounting table 12 is 350 mm, and is formed so as to be smaller than the inner diameter of the water tub 6 of almost all washing machines. The side of the mounting table 12 that faces the support portion 14 is formed in a semicircular shape. The mounting table 12 and the support part 14 are arranged apart from each other. When the water tank unit 18 is disposed on the mounting table 12, the side of the mounting table 12 facing the support portion 14 is disposed inside the water tank 6 and abuts against the balancer 8. That is, a part of the water tank 6 can be dropped between the mounting table 12 and the support part 14. The mounting table 12 can be brought into direct contact with the balancer serving as the accommodating portion, and stable drilling of the balancer can be performed.

  In drilling the balancer 8, the notch blade 15 is moved toward the balancer 8 as indicated by an arrow 103. It is the same as in the case of the aquarium unit that the notch blade 15 pierces the inner surface of the balancer 8 and a part of the balancer 8 is cut out so as to include the top surface of the balancer 8. Thus, in the drilling apparatus in the present embodiment, the workpiece can be drilled not only in the dewatering tank unit and the balancer alone but also in the water tank unit.

  In the second drilling device shown in FIG. 15, the mounting table 12 and the support portion 14 are integrally formed. By adopting this configuration, the configuration of the drilling device can be simplified. In the second drilling device, the operation and effect when the dewatering tank unit and the balancer are drilled are the same as those of the first drilling device in the present embodiment.

  When the object to be processed is a water tank unit, as shown in FIG. 15, the top surface of the water tank 6 and the mounting surface of the mounting table 12 come into contact with each other. The top surface of the balancer 8 of the dewatering tank unit 17 is separated from the mounting table 12.

  FIG. 16 shows an enlarged view when the notch blade 15 is moved in the direction indicated by the arrow 102. Since the height of the notch blade 15 is arranged so as to contact the lower side of the inner surface of the balancer when the dewatering tank unit is arranged as the object to be treated, the water tank unit 18 is arranged as the object to be treated. In this case, the notch blade 15 may come into contact with the top surface of the balancer 8. In this case, a hole that penetrates the balancer 8 in the thickness direction cannot be formed, or the balancer escapes upward and cannot be drilled. For this reason, when the mounting table 12 and the support part 14 are formed integrally, it is preferable to determine the height of the notch blade 15 by determining the workpiece to be processed.

  For example, when the object to be treated is a water tank unit, it is preferable to arrange the notch blade 15 at a higher position so that the notch blade 15 contacts the lower part of the inner surface of the balancer 8. Or it is preferable that the position adjustment means of the notch blade which can adjust the height of a notch blade is arrange | positioned.

  Next, a preferred positional relationship between the notch blade and the balancer, a preferred contact angle, and a preferred stroke of the notch blade will be described.

  The drilling device in the present embodiment includes the top surface of the balancer, and is drilled so as to penetrate in the thickness direction of the balancer. In order to perform such excision, the height of the lower end of the notch blade (in this embodiment, the end of the mountain-shaped skirt in the cross-sectional shape) is preferably arranged lower than the lower end of the balancer. The stroke of the notch blade is preferably long enough to cut off the lowermost part of the balancer.

  FIG. 17 is a side view for explaining the positional relationship between the notch blade and the balancer, and FIG. 18 is a perspective view after the drilling device is driven. In FIG. 17, the lower end of the notch blade 15 is arranged to be higher than the lower end of the balancer 8. In such an arrangement, although the notch blade 15 penetrates the balancer 8, as shown in FIG. 18, only a through hole 44 is formed in the balancer 8, and a part of the balancer 8 cannot be excised. In this state, the opening area is small and the discharge efficiency of salt water is deteriorated. Moreover, the salt water remaining inside the balancer increases.

  Further, the notch blade 15 may come into contact with the dewatering tank 7. At this time, if the dewatering tank 7 is made of resin, it is only necessary to form a hole in the dewatering tank 7 like the balancer. However, if the dewatering tank 7 is made of stainless steel, the notch blade 15 is deformed or damaged. .

  On the other hand, if the position of the notch blade is too low with respect to the balancer, the notch blade comes into contact with the top surface of the balancer and cutting cannot be performed so as to penetrate in the thickness direction of the balancer. In some cases, the balancer escapes and cannot be excised. In particular, when a notch blade having an arc shape in cross section is used, there arises a problem that it cannot be excised.

  The position in the height direction at which the notch blade contacts the balancer is preferably a position that is 10 mm or more and 12 mm or less away from the mounting surface in a direction perpendicular to the mounting surface. Referring to FIG. 6, when the drilling device is a device for drilling holes in the balancer, it is preferable that the distance d21 is 10 mm or more and 12 mm or less when the balancer thickness t21 is 40 mm. That is, the notch allowance from the top surface on the inner surface of the balancer is preferably 10 mm or more and 12 mm or less. By adopting this configuration, it is possible to reliably pierce the notch blade into the inner surface of the balancer, and to make a hole over the entire thickness direction of the balancer.

  As shown in FIG. 14, in the first drilling device in the present embodiment, when a water tank unit 18 is disposed as an object to be processed, there is a gap between the dewatering tank unit 17 and the water tank 6, so The distance d22 which is the cost becomes small. However, the decrease of the notch allowance is slight, and as shown in FIG. 6, when a balancer having a thickness t21 of 40 mm is arranged, the distance d21 as the notch allowance is not less than 10 mm and not more than 12 mm. Even when the object to be treated is a water tank unit, it is possible to make a good hole in the balancer.

  Referring to FIG. 1, in the present embodiment, the mounting table is inclined by 15 ° with respect to the moving direction of notch blade 15. Since the air cylinder 16 can be brought closer to the balancer 8 by increasing the inclination angle of the mounting table 12 with respect to the moving direction of the notch blade 15, the length in the depth direction of the device is shortened, and the size of the device is reduced. Can be achieved.

  On the other hand, if the angle of the moving direction of the notch blade 15 with respect to the inner surface of the balancer 8 becomes too large (if the angle formed by the mounting surface of the mounting table and the moving direction of the notch blade becomes too large), the notch blade becomes a balancer. When the inner surface of 8 is contacted, a force in a direction other than the moving direction is applied to the notch blade 15, so that the notch blade is difficult to pierce the balancer or a component such as the air cylinder 16 breaks down. Therefore, in consideration of the stability of excision, the approach angle of the notch blade 15 with respect to the inner surface of the balancer 8 is preferably 90 °. In consideration of the miniaturization of these devices and the stability of excision, the angle formed by the moving direction of the notch blade 15 and the mounting surface of the mounting table is preferably 10 ° or more and 20 ° or less.

  FIG. 19 shows a side view for explaining the stroke of the notch blade, and FIG. 20 shows a perspective view after driving the drilling device and an enlarged perspective view of the formed hole portion. In FIG. 19, the notch blade 15 is disposed so that the lower end thereof is lower than the lower end of the balancer 8, but the stroke of the notch blade is insufficient, and the lowermost portion 45 of the balancer is not cut off. . In this case, as shown in FIG. 20, the hole 41 is formed, but the cut-out portion 43 remains attached to the main body of the balancer 8. As a result, the cut-off portion 43 obstructs the saltwater discharge path, and the saltwater discharge efficiency is reduced.

  In particular, when the cutting edge of the notch blade 15 is sharp, if the stroke of the notch blade is insufficient, the cutting edge penetrates the balancer 8, but the lowermost portion 45 of the balancer 8 does not leave the balancer 8 body. May remain. Therefore, it is preferable that the balancer has a sufficient stroke so that the lowermost portion 45 of the balancer 8 is cut off.

  The drilling device in the present embodiment includes an automatic driving device and a safety control device. By providing the automatic driving device, the burden on the operator can be reduced. In addition, the occurrence of trouble or disaster can be suppressed by providing the safety control device. Furthermore, the automatic operation of the present apparatus can be stopped in the event of an emergency evacuation of the worker accompanying the occurrence of a trouble, ensuring the safety of the worker and preventing secondary disasters.

  In the drilling device of the present embodiment, a support structure that restricts movement of the notch blade in a direction other than the moving direction and an edge cutting structure in which the connection between the notch blade and the air cylinder is not completely fixed are employed. Of these structures, preferably, by adopting at least one of both, a load other than the moving direction applied to the notch blade can be canceled, so that deformation or breakage of the air cylinder or the guide rod can be prevented.

  In the present embodiment, a description has been given of a drilling device for an object to be stored in an upside down state. However, the present invention is not particularly limited to this configuration. For example, according to the form of an object to be processed, It is also possible to apply to a device that performs processing in a state of being placed (turned down). In this apparatus, the configuration of the apparatus in the present embodiment may be used as it is, and a drilling apparatus arranged so that the notch blade moves from the upper side to the lower side may be used. By adopting this configuration, it is possible to use the mounting table as a support part, and it is possible to easily and efficiently drill a hole to be processed that is placed sideways.

  In the present embodiment, a drilling device that drills holes in the balancer of the washing machine has been described. However, the present invention is not limited to this mode, and can be applied as a drilling device that drills holes in arbitrary members. For example, it can be used as a drilling device for making a hole in a drum can containing a fluid waste or a fluid dangerous material and collecting the fluid inside.

  The fluid inside the housing part is not limited to a liquid, and may be a gas, for example. When the fluid accommodated in the interior of the accommodating portion is a gas, it is suitable for a drilling device for the accommodating portion in which a gas having a higher specific gravity than air is accommodated. In the case of a gas having a specific gravity greater than that of air, the gas can be easily recovered from the lower side of the apparatus as in the present embodiment.

  The recycled resin in the present embodiment is recovered by removing the fluid from the housing portion formed of the resin using the drilling device based on the present invention. The drilling device according to the present invention can greatly reduce the fluid remaining in the accommodating portion, and can provide a high-quality recycled resin. In addition, since the working efficiency is improved, an inexpensive recycled resin can be provided.

  Moreover, the resin product based on this invention is formed using the recycled resin collect | recovered using the drilling apparatus based on this invention. By adopting this configuration, it is possible to provide a high-quality and inexpensive resin product.

  In FIG. 22, the perspective view of the notch blade in this Embodiment is shown. The cutout blade 25 in the present embodiment has a circular cross section. The notch blade 25 is formed so that the tip is sharp. In the drilling device, the notch blade 25 is arranged so that the top of the arcuate cross section faces upward.

  The mounting table 22 is formed in a flat plate shape and includes an opening formed so that the notch blade 25 can move. The notch blade 25 is disposed so that a part thereof protrudes from the opening of the mounting table 22 onto the mounting surface. The support portion 24 is formed in a plate shape and is disposed so that the main surface is parallel to the vertical direction. The portion of the support portion 24 that comes into contact with the object to be processed has a main surface formed in an arc shape. An opening is formed in the support portion 24 so that the notch blade 25 can move.

  FIG. 23 is an explanatory diagram of the fixing means in the present embodiment. In the present embodiment, two fixing means are formed on both sides of the notch blade. The fixing means includes a support portion 24 and a facing portion 23. The facing portion 23 includes a contact portion 46 that protrudes toward the support portion 24. The facing portion 23 is formed to move as indicated by an arrow 109 with the support portion 35 as a fulcrum.

  In the facing portion 23, the side opposite to the side where the contact portion 46 is formed is supported by the shaft 30. The shaft 30 is connected to the facing portion air cylinder 27. When the opposed portion air cylinder 27 is driven, the shaft 30 is formed to move in the direction indicated by the arrow 108. Thus, in the present embodiment, the abutting portion 46 of the facing portion 23 is formed so as to move toward or away from the support portion 24 by driving the facing portion air cylinder 27.

  Since other configurations are similar to those of the first embodiment, description thereof will not be repeated here.

  With respect to the height at which the notch blade 25 protrudes from the mounting surface of the mounting table 22, a large hole can be formed in the balancer 8 by increasing the height of the notch blade 25 to be protruded from the mounting surface. However, the driving force of the notch blade 25 increases, and the air cylinder 26 increases in size. The height at which the notch blade 25 protrudes from the mounting surface is preferably determined in consideration of the size of the cross section of the notch blade 25 and the size of the air cylinder 26 for driving the notch blade 25.

  Further, in the present embodiment, the height of the notch blade 25 with respect to the mounting surface is formed to be constant. However, the height of the notch blade 25 is not particularly limited, and the height of the notch blade 25 can be adjusted. It is preferable to be formed. For example, the position of the top of the balancer differs depending on whether the object to be processed is a water tank unit or a dehydration tank unit. Thus, the height of the notch blade can be adjusted, and the balancer can be cut at an optimum position.

  Since other operations and effects are the same as those in the first embodiment, description thereof will not be repeated here.

(Action / Effect)
Referring to FIG. 28, worker 91 works while standing on the front side of the dismantling apparatus. First, the water tank unit 18 as an object to be processed is disposed on the mounting surface of the mounting table 61. The aquarium unit 18 is arranged so that the balancer faces the mounting table 61 by turning upside down.

  FIG. 31 shows a front view when the mounting table is raised. Referring to FIG. 31, next, the elevating unit 75 is extended and the mounting table 61 is moved upward as indicated by an arrow 123. At this time, the operator holds the presser bar 71 by hand, and adjusts the position so that the presser plate 72 contacts the bottom surface of the water tank unit 18. The mounting table 61 is raised with the opening / closing claw 80 opened in advance.

  Referring to FIG. 30, next, the claw driving unit 82 is driven to move the opening / closing claw 80 in the closing direction. In this way, the reduction gear unit 5 disposed on the bottom surface of the water tank 6 is hooked by the opening / closing claw 80.

  Next, referring to FIG. 31, the hydraulic cylinder 90 is driven to raise the opening / closing claw 80 upward as indicated by an arrow 123. By pulling up the opening / closing claw 80, the presser plate 72 comes into contact with the bottom surface of the water tank unit 18. The water tank unit 18 is fixed by the pressing plate 72 coming into contact with the bottom surface of the water tank unit 18. When the presser plate 72 comes into contact with the bottom surface of the water tank unit 18, the raising of the opening / closing claw 80 is temporarily stopped. In this state, the water tank unit 18 is slightly lifted by the opening / closing claw 80, and the mounting table 61 and the water tank unit 18 are separated from each other.

  Next, the elevating unit 75 is driven again to raise the mounting table 61, and the mounting table 61 and the water tank unit 18 are brought into contact with each other. Referring to FIG. 30, by driving air cylinder 52 in this state, needle 53 is raised and a hole is made in balancer 8 arranged inside water tank unit 18. When the drilling is completed, the needle 53 is retracted and returned to the original starting position.

  FIG. 32 is a partial cross-sectional view when the reduction gear unit and the dewatering tank unit are disconnected. When the drilling of the balancer is completed, the lifting of the opening / closing claw 80 is resumed. As shown in FIG. 32, when a force that causes the reduction gear unit 5 indicated by the arrow 123 to move away from the water tank 6 is applied, the dehydration tank 7 and the rotor blade (pulsator) 63 are driven inside the reduction gear unit 5. The rotating shaft 66 is detached from the reduction gear unit 5. Thus, the reduction gear unit 5, the water tank 6, and the dewatering tank unit 17 can be easily separated. As a result, it is possible to recover the water tank 6 without damaging it, and it is possible to recover a good quality water tank resin.

  Thus, the dismantling apparatus in this Embodiment can collect | recover the resin of a water tank from a water tank unit easily, and can remove the salt water inside a balancer.

  The mounting table moving unit and the driving unit moving unit in the present embodiment are formed to move in a direction substantially perpendicular to the mounting surface. By adopting this configuration, it is possible to more reliably separate the water tank from the water tank unit and more reliably make a hole in the balancer.

  In the present embodiment, the opening / closing claw and the mounting table are formed independently and independently so as to move in the vertical direction. However, the mounting table moving means is not limited to this mode. It may be configured to move in synchronization with the means. By adopting this configuration, the working time can be shortened and the working efficiency can be improved. For example, after the drive unit is sandwiched between the opening and closing claws, the water tank unit may be pulled up and the mounting table raised to bring the bottom surface of the water tank into contact with the pressing means.

  Since other operations and effects are the same as those of the third embodiment, description thereof will not be repeated here.

  In addition, the said embodiment disclosed this time is an illustration in all the points, Comprising: It is not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and includes all modifications within the scope and meaning equivalent to the terms of the claims.
