Description

  The present invention relates to a cleaning device set.

  In recent years, the use of CFCs as a gas that destroys the ozone layer has been banned. Fluorocarbon is an artificial gas that does not exist in nature, and has been used in a wide range of fields such as refrigerant gas for air conditioners and refrigerators, foaming gas for heat insulating materials, spray propellants, and the like. In addition, since chlorofluorocarbon has a high detergency, it has also been used as a cleaning agent for cleaning fats and the like adhering to parts of industrial products such as machine products. However, since the use of chlorofluorocarbon is prohibited because it is a substance that destroys the ozone layer, alternative chlorofluorocarbons such as HFCs and HCFCs have been researched and developed as substitutes for chlorofluorocarbons.

  Alternative chlorofluorocarbons have inferior cleaning power compared to chlorofluorocarbons and may have different cleaning power depending on the type of fat, for example. In addition, since some alternative chlorofluorocarbons are said to cause global warming, new chlorofluorocarbons are being developed in place of alternative chlorofluorocarbons. This new chlorofluorocarbon also has poor detergency compared to chlorofluorocarbon, and for example, the detergency may differ depending on the type of fat.

  For this reason, for example, when a new chlorofluorocarbon was developed, the cleaning power according to the fat content was tested using a beaker or the like on a desk in the laboratory. However, solvent cleaning devices that clean fats and the like adhering to parts such as machine products include, for example, various cleaning tanks such as boiling cleaning tanks and ultrasonic cleaning tanks, and parts conveying devices for moving parts. There are known cleaning apparatuses that automatically immerse parts to be cleaned in these tanks in order and automatically clean them (see, for example, Patent Document 1 and Patent Document 2). Since the cleaning conditions differed from the cleaning performed in step 1, accurate cleaning evaluation could not be performed.

  Buffers 115 and 116 are affixed to the inside of the case body 111 and the inside of the lid 112 so that external forces from the outside and stored items do not collide with each other during transportation or storage. . The buffer bodies 115 and 116 may be anything as long as they can protect the solvent cleaning device 1 and the like housed in the case main body 111. For example, the buffer bodies 115 and 116 may have appropriate hardness such as synthetic rubber, natural rubber, and urethane resin. In addition, a material having elasticity is preferable, and urethane resin is particularly preferable.

  The buffer body 115 of the case body 111 is provided with a recess 117 corresponding to the outer shape of the solvent cleaning device 1, the container 102 and the accessory 103, so that the solvent cleaning device 1, the container 102 and the accessory 103 stored in the case body 111 It is preferable to prevent the positions from shifting, that is, to prevent the objects stored during transportation from colliding with each other.

  The container 102 can be filled with a liquid such as a chlorofluorocarbon solvent provided to the solvent cleaning apparatus 1 and may be any container that can be opened and closed with a lid or the like. The container 102 is formed in a cylindrical shape, for example, from a material that can store a fluorocarbon solvent for a long period of time.

  The number of containers 102 may be one, two or more, for example four.

  The container 102 is preferably formed so that a necessary amount of liquid, particularly a chlorofluorocarbon solvent, can be placed in the solvent cleaning apparatus 1. In this case, when there are a plurality of containers 102, the containers may be formed so that the necessary amount of the chlorofluorocarbon solvent is contained in the solvent cleaning apparatus with two or more containers, but preferably one container 102. Therefore, it is preferable to form the container so that a necessary amount of the chlorofluorocarbon solvent enters the solvent cleaning apparatus 1.

  The container 102 is, for example, a chlorofluorocarbon solvent container that stores the chlorofluorocarbon solvent and collects the chlorofluorocarbon solvent after contributing to cleaning of the object to be cleaned. When there are four containers 102, at least one is preferably a chlorofluorocarbon solvent container. In addition, when there are four containers 102, it is preferable to use two or more chlorofluorocarbon solvent containers, and each chlorofluorocarbon solvent container may contain different types of chlorofluorocarbon solvents. Examples of the fluorocarbon solvent include HFCs, HFEs, HCFCs, and the like.

  The accessory 103 can drive the solvent cleaning apparatus 1 to clean the object to be cleaned. Particularly, the accessory 103 is necessary when the solvent cleaning apparatus 1 is driven to clean the object to be cleaned, for example, the solvent cleaning apparatus. 1, a power source 121 for driving 1, a placing tool (not shown) such as a basket for placing the object to be cleaned and cleaning, a jig (not shown) for holding or hooking the object to be cleaned 1), an operation panel (not shown) such as a switch for operating the solvent cleaning apparatus 1, a tool (not shown), and the like. These mounting tools, jigs, operation panels such as switches, and tools are preferably stored in the case 101 in the parts box 122. Other accessories 103 include, for example, a funnel 123 for injecting a chlorofluorocarbon solvent into the solvent cleaning apparatus 1 and a syringe 124 for recovering the chlorofluorocarbon solvent from the solvent cleaning apparatus 1.

  The solvent cleaning device 1 may be any device as long as it can be stored in the case 101. 3 to 27 show the solvent cleaning apparatus of the present invention.

  As shown in FIGS. 3 to 27, as the solvent cleaning apparatus 1, specifically, for example, cleaning tanks 3 to 5 for cleaning (including degreasing) the component 2 to be cleaned using a fluorocarbon solvent, , A heater 7 for heating and evaporating the chlorofluorocarbon solvent, a cooler 8 for condensing and recovering the vapor of the chlorofluorocarbon solvent, and a component conveying device for holding the components 2 and immersing them in the cleaning tanks 3 to 5 9, a rotation driving device 10 that relatively rotates one of the component conveying device 9 and the cleaning tanks 3 to 5, and a lifting / lowering driving device 11 that raises and lowers the component conveying device 9. A distillation-integrated apparatus for evaporating and distilling a solvent to maintain the cleanliness of a cleaning chlorofluorocarbon solvent, wherein at least one of a rotation driving device 10 and a lifting / lowering driving device 11 is disposed above cleaning tanks 3 to 5. Along with these rotary drive devices 10 Those that are detachable with respect to the cleaning tank 3-5 those disposed above the cleaning tank 3-5 of finely lift drive unit 11.

  Below, about the solvent washing | cleaning apparatus 1 which arrange | positioned both the rotational drive apparatus 10 and the raising / lowering drive apparatus 11 above the washing tanks 3-5, and also made both these rotation drive apparatuses 10 and the raising / lowering drive apparatus 11 removable. explain. In the present embodiment, a compact structure in which the space occupied by the entire apparatus is reduced by adopting a distiller-integrated structure in which both the rotary drive device 10 and the lift drive device 11 are arranged above the cleaning tanks 3 to 5 in this way. The device is realized.

  The solvent cleaning apparatus 1 has three round-bottomed washing tanks 3 to 5 and a single round-bottomed or flat-bottomed drying tank 6 like test tubes. The component 2 immersed in 5 and washed stepwise is dried in a drying tank 6 (see FIG. 5). These four tanks 3 to 6 are arranged on the rotating disk 30 at equal intervals around the vertical rotating shafts 14 and 15 to form a rotating washing tank that rotates in the drain tank 17 in an integrated state. (See FIG. 4). In addition, a punching metal 16 that prevents the chlorofluorocarbon solvent in the drain tank 17 from splashing but allows the fluorocarbon solvent vapor to pass through is fixed to the bottom of the rotating disk 30 with screws 16b via spacers 16c. (See FIGS. 4 and 17). The punching metal 16 is provided with a recess 16a slightly larger than each of the tanks 3 to 6 into which the tanks 3 to 6 can be fitted (see FIG. 7). When ultrasonic waves are applied, the chlorofluorocarbon solvent containing oil in the drain tank 17 bubbles or mists and rises from the liquid surface. This punching metal 16 becomes a physical obstacle and the physics of the fluorocarbon solvent vapor. Energy is absorbed so that excess chlorofluorocarbon solvent vapor is not brought into each tank 3-6. If there is no small hole in the metal, it is possible to completely suppress the problem of excess chlorofluorocarbon solvent vapor being brought into each of the tanks 3 to 6, but this causes another problem that the chlorofluorocarbon solvent cannot be regenerated. It is desirable to determine the size, number, arrangement, etc. of the small holes in the punching metal 16 by comparing the defects. In addition, although one punching metal 16 is sufficient, when a plurality of punching metals 16 are used, it is possible to more reliably absorb the energy of the fluorocarbon solvent vapor.

  These tanks 3 to 6 are arranged in the order of processing performed on the component 2. For example, in the present embodiment, the first cleaning tank 3, the second cleaning tank 4, the third cleaning tank 5 and the drying tank 6 are arranged on the rotating disk 30 in this order clockwise (see FIG. 5). The rotating disk 30 (and the punching metal 16) is rotated counterclockwise. Each of the tanks 3 to 6 is installed at a height at which the bottom of the tanks 3 is immersed in the waste liquid in the drain tank 17, and is poured into the hot water through the heated waste liquid (see FIG. 4).

  Further, in the three cleaning tanks 3 to 5, the fluorocarbon solvent overflowed from the third cleaning tank 5 flows into the second cleaning tank 4, and the fluorocarbon solvent overflowed from the second cleaning tank 4 is the first. In order to flow into the cleaning tank 3, the liquid level is gradually lowered in the order of the third cleaning tank 5 → the second cleaning tank 4 → the first cleaning tank 3 (see FIG. 6). For this reason, the degree of cleanliness of the chlorofluorocarbon-based solvent after flowing into the third cleaning tank 5 gradually decreases as it flows from the second cleaning tank 4 to the first cleaning tank 3, and thus the cleaning tank. The degree of cleanliness of the chlorofluorocarbon solvent in the second cleaning tank 4 is higher than that of the first cleaning tank 3, and the third cleaning tank 5 is higher than the second cleaning tank 4. The third cleaning tank 5 and the second cleaning tank 4 are provided with flow paths 18 and 19 that guide the overflowing fluorocarbon solvent to the lower cleaning tank (the second cleaning tank 4 or the first cleaning tank 3). It has been. The first cleaning tank 3 is provided with a waste liquid port 20 for draining the chlorofluorocarbon solvent to the drain tank 17 (see FIG. 5).

  In the present embodiment, the component 2 is roughly cleaned in the first cleaning tank 3 in which the component 2 is first immersed, and the chlorofluorocarbon solvent in the cleaning tank 3 is heated to boil and distill (hereinafter referred to as the following). The first cleaning tank having the main function of “ultrasonic wave + boil cleaning” is also referred to as “boil cleaning tank”). The fluorocarbon solvent that has flowed into the boiling washing tank 3 is thereby vaporized or discharged into the drain tank 17 through the above-described waste liquid port 20. Further, in the second cleaning tank 4, the component 2 after the rough cleaning is ultrasonically cleaned (hereinafter, this second cleaning tank having a main function of “ultrasonic wave + rinse” is also referred to as “ultrasonic rinse tank”). ). An ultrasonic transducer 21 that generates ultrasonic waves is provided at the bottom of the drain tank 17 (see FIG. 3 and the like). Although not particularly shown in the present embodiment, a circulating path for circulating the fluorocarbon solvent and returning it to the original is provided at the bottom of the boiling washing tank 3 in some cases, and this circulating path includes a valve and a Y-type strainer. A pump, a pressure gauge, a filter case, etc. are provided. Further, in the third cleaning tank 5, final cleaning is performed with a fluorocarbon solvent having the highest cleanliness (hereinafter, this third cleaning tank having a main function of “ultrasonic wave + final rinse” is referred to as “final cleaning tank”. ”).

  In the final cleaning tank 5, the high purity of the chlorofluorocarbon solvent in the tank is maintained by the flow of distilled purified chlorofluorocarbon solvent. In the present embodiment, a liquid collection dish 22 is provided at the upper center of the rotating disk 30 so that the distilled chlorofluorocarbon-based solvent dripped on the dish flows into the final cleaning tank 5 (see FIGS. 4 and 5). In this case, in consideration of the fact that moisture may be mixed in the inflowing fluorocarbon solvent, a water separation mechanism 12 is provided for separating this water from the viewpoint of preventing the occurrence of rust on the surface of the component. Preferably it is. In the present embodiment, the partition plate 12a subjected to the water repellent treatment is provided in the upper layer portion including the liquid surface of the chlorofluorocarbon solvent, and the inside of the final cleaning tank 5 is divided into the cleaning area A1 and the external area A2 other than that, Thus, the water that has flowed into the external region A2 is prevented from flowing into the cleaning region A1 (see FIGS. 5 and 6). In this case, the cleaning area A1 has a size that allows at least the component 2 to be lowered together with the component holder 46 and immersed in the bath. In the present embodiment, since a liquid having a specific gravity greater than that of water is used as the chlorofluorocarbon solvent, the water flowing into the final cleaning tank 5 flows out of the tank in a state of floating on the surface layer of the chlorofluorocarbon solvent. Therefore, it is possible to prevent water from staying in the final cleaning tank 5 as much as possible. Further, since the water separation mechanism 12 is formed by a simple configuration in which the partition plate 12a is provided in the final cleaning tank 5, compared to the case where a device for water separation is provided separately from the solvent cleaning device 1. This is advantageous in terms of downsizing the apparatus.

  The drying tank 6 is a tank for drying the surface of the finally cleaned component 2 and is arranged as a fourth tank positioned next to the final cleaning tank 5 (see FIG. 5 and the like). The drying tank 6 has a main function of “vapor cleaning + drying” (that is, a function of performing vapor cleaning and a function of performing drying).

  Further, in the rotary cleaning tank as described above, it is also preferable to partition the space above the tank, which requires particularly cleanliness, from other parts. In such a case, it is possible to keep the atmosphere of the part 2 in the final stage of cleaning or the final process clean. In this embodiment, the partition walls 29 are provided so as to partition the upper space of the drying tank 6 and the final cleaning tank 5 from the upper space of the boiling cleaning tank 3 and the ultrasonic rinse tank 4 (see FIG. 5). The partition wall 29 is bent in a V shape near the center so as not to interfere with the shafts 14 and 15 and the liquid collection tray 22.

  The rotation driving device 10 for rotating the rotary cleaning tank composed of the cleaning tanks 3 to 5, the drying tank 6, the rotating disk 30 and the punching metal 16 includes a cleaning tank rotating motor 23, a timing belt 24, pulleys 25 and 26, and a shaft. 14 and 15 (see FIGS. 3 and 13 to 15). In the present embodiment, a vertically installed DC geared motor is used as a washing tank rotation motor 23, and power is transmitted to the shafts 14 and 15 by a timing belt 24. The rotation amount of the cleaning tank rotation motor 23 can be detected by a rotation sensor dog 27 which is attached to the rotation shaft of the cleaning tank rotation motor 23 and rotates by the same amount, and a rotation sensor 28 which reads the rotation amount of the dog (FIGS. 13 and 13). 15). From the viewpoint of avoiding the influence of the chlorofluorocarbon solvent vapor flowing out from the upper opening of the cooling pipe 61, the cleaning tank rotation motor 23, the rotation sensor dog 27, and the rotation sensor 28 are in front (or rear) of the upper opening and It is preferable that it is installed below.

  The shafts 14 and 15 are double shafts having a double structure for integrally rotating the washing tanks 3 to 5 and the drying tank 6 through the rotating disk 30 (see FIG. 4). Of these two shafts, the shaft 14 is a hollow shaft having a pulley 26 attached to the outer periphery, and the power is transmitted by a timing belt 24 wound around the pulley 26 to rotate. On the other hand, the shaft 15 is a solid axis longer than the hollow shaft 14, and can rotate in the hollow shaft 14 and move in the axial direction (that is, the vertical direction) (see FIG. 13). These shafts 14 and 15 have an engagement / disengagement mechanism 31 having the following structure, for example, which can be selected from a locked state in which both shafts 14 and 15 rotate integrally or a non-locked state in which they do not rotate integrally. (See FIGS. 4 and 8). That is, a cap member 32 that rotates integrally with the upper shaft end of the solid shaft 15 is attached, and a drive pin 33 that protrudes toward the center of rotation is provided at the cap portion. A crank-shaped engagement groove 34 is provided in the crank member 35 attached to a portion facing 33. The engagement groove 34 rotates the shafts 14 and 15 integrally with a position where a later-described locking pin 38 is not hooked on the joint block 36 (drive portion removal position) and the locking pin 38 is hooked on the joint block 36. It has a crank shape with a rotational position at a position opened approximately 90 degrees (see FIG. 8). Further, a step is provided between the rotation position and the removal position, and the rotation position is higher than the removal position by the level difference. Therefore, in order to move the drive pin 33 in the removal position to the rotation position, it is necessary to perform an operation of rotating 90 degrees while overcoming the step on the way. In the present embodiment, the height of the drive pin 33 at the rotational position is made higher than that at the removal position, and the solid shaft 15 is moved upward by the height during rotation. An engaging claw 35a for engaging the drive pin 33 with the crank member 35 is provided at the rotational position (see FIG. 8). When the driving pin 33 is engaged with the engaging claw 35a, the rotational driving force of the washing tank rotating motor 23 is motor 23 → pulley 25 → timing timing belt 24 → pulley 26 → shaft 14 → crank member 35 → driving pin. 33 → shade member 32 → shaft 15 is transmitted.

  Moreover, the lower end part of the hollow shaft 14 and the solid shaft 15 becomes a structure which can be attached or detached with respect to the rotation disc 30 (refer FIG. 4, FIG. 9). For example, in the present embodiment, a joint block 36 is provided on the liquid collection tray 22, and the lower ends of the shafts 14 and 15 can be attached to or detached from the joint block 36. The lower end of the hollow shaft 14 is provided with, for example, a quadrangular prism-shaped engagement block 37 having an engagement protrusion 37a, and the joint block 36 is provided with an engagement block 37 (and an engagement protrusion, for example, by protrusions at four corners as shown). A recess in which 37a) fits is formed. In a state where the engagement block 37 (and the engagement protrusion 37a) are fitted in the concave portion of the joint block 36, the rotating disk 30 (and each of the tanks 3 to 6) and the hollow shaft 14 are not integrally rotatable. Engage with.

  Further, a locking pin 38 that protrudes horizontally from the shaft 15 is provided near the lower end of the solid shaft 15, while a long hole 39 through which the locking pin 36 can pass is provided in the joint block 36. (See FIG. 9). After the lower end portion of the solid shaft 15 and the locking pin 38 are inserted into the long hole 39, when the locking pin 38 is rotated together with the solid shaft 15, the locking pin 38 is locked and the solid shaft 15 is locked. The joint block 36 cannot be removed. At this time, since the engagement block 37 is already fitted in the joint block 36, the hollow shaft 14 and the joint block 36 are integrated and rotate by the same amount. Further, when the locking pin 38 is rotated together with the solid shaft 15, the driving pin 33 is simultaneously locked with the locking pin 38 by the joint block 36 by rotating it 90 degrees while being lifted so as to exceed the step. Can be engaged with the rotational position of the crank member 35 (see FIG. 8). Thereby, the hollow shaft 14, the solid shaft 15, the joint block 36, the rotating disk 30 and the like are integrated and rotated by the same amount. In addition, as the drive pin 33 is lifted by the crank step of the engagement groove 34, the solid shaft 15, the locking pin 38, the joint block 36, the rotating disk 30, the punching metal 16, the tanks 3-6, etc. The same amount can be lifted. In this embodiment, until the rotary disk 30 is locked to the inner wall of the drain tank 17 until it is lifted in this way, the tanks 3 to 6 are kept in a non-rotatable state and the rotary disk 30 is lifted. Thus, the locked state is released so that the tanks 3 to 6 can be rotated.

  Subsequently, a structure for liquid replacement and liquid amount confirmation of the cleaning fluorocarbon solvent in the solvent cleaning apparatus 1 of the present embodiment will be described.

  In the present embodiment, a waste liquid drain pipe 40 for draining the chlorofluorocarbon solvent accumulated in the drain tank 17 is installed on the outer peripheral side of the drain tank 17 (see FIGS. 3 and 16 to 17). The waste liquid drain pipe 40 communicates with the lower part of the drain tank 17 through a communication pipe 40a at the lower part thereof, and has a structure capable of turning in a vertical plane around the horizontal communication pipe 40. A plug 40c is provided at the tip of the swivelable tube portion 40b (see FIG. 3). When this tip is always held at a position higher than the liquid level in the drain tank 17 except during waste liquid. It is also possible to omit the stopper 40c. On the outer periphery of the drain tank 17, a holding device 40d for keeping the pipe portion 40b vertical is provided (see FIG. 17). By depressing the tube portion 40b, the chlorofluorocarbon solvent in the drain tank 17 can be drained.

  Further, a drain tank liquid level pipe 41 is provided on the outer periphery of the drain tank 17 so that the amount of waste liquid in the tank can be visually recognized (see FIGS. 3 and 16 to 18). The drain tank liquid level pipe 41 is provided at the upper and lower portions of the drain tank 17 and communicates with the communication pipes 41a and 41b and the transparent or translucent tube 41c provided between the communication pipes 41a and 41b. It consists of and. According to the drain tank liquid level pipe 41, the height of the waste liquid at that time in the drain tank 17, that is, the amount of the waste liquid accumulated in the tank can be confirmed by visually checking the liquid level in the tube 41c. .

  Next, the component conveying device 9 will be described. The component conveying device 9 is a device that supplies the component 2 to the solvent cleaning device 1 or discharges the cleaned component 2 from the solvent cleaning device 1 (in this specification, the supply operation and the discharge operation are collectively referred to as “delivery”). Called). In the solvent cleaning apparatus 1 of the present embodiment, the cleaning process is sequentially advanced by moving the tanks 3 to 6 together with the rotating disk 30 while moving up and down a plurality of times at the position while holding the component 2. doing. Hereinafter, the configuration of the component conveying apparatus 9 will be described (see FIGS. 3, 10, 11, 19 to 23, etc.). The “intermediate position” shown in FIG. 11 is a stop position when the component 2 is stopped at the position where the chlorofluorocarbon solvent vapor exists when the part 2 is moved between the cleaning tanks 3 to 5. Further, “drying position” indicates a part position (height) in the drying tank 6.

  In the present embodiment, the component conveying device 9 includes a pair of left and right upper and lower guide shafts 42 and 43, a bridge 44 connecting the upper ends of the upper and lower guide shafts 42 and 43, a component holding component 45 provided in the middle of the bridge 44, and the like. The component 2 held on the component holder 46 at the lower end of the component holding component 45 is moved up and down together with the upper and lower guide shafts 42, 43, etc. (see FIG. 3). The upper and lower guide shafts 42 and 43 are guided in the vertical direction by the upper and lower guide bearing portions 50 provided in the upper portions of the tanks 3 to 6 and the drain tank 17. The up / down amount of the upper and lower guide shafts 42 and 43 is detected by an upper / lower sensor dog 51 attached to one upper / lower guide shaft (for example, the upper / lower guide shaft 43) and moving up / down by the same amount, and an up / down sensor 52 that reads the up / down amount of the upper / lower sensor dog 51. (See FIG. 3).

  A component holding component 45 for holding the component 2 is suspended substantially at the center of the bridge 44 (see FIG. 10 and the like). An attachment member 48 is provided at the upper end of the component holding component 45 so that the component holding component 45 itself can be attached to and detached from the bridge 44. The material for connecting the mounting member 48 and the component holder 46 is not particularly limited in material, thickness, shape, etc., but it has as little surface area as possible in contact with the fluorocarbon solvent when the component 2 is immersed. Preferably, when the surface area is reduced in this way, the amount of the fluorocarbon solvent adhering to the connecting member can be reduced each time the component 2 is moved up and down, and the evaporation amount of the fluorocarbon solvent can be suppressed. Become. For example, in this embodiment, two steel wires 47 are suspended in parallel, and the component holder 46 is supported at the lower end thereof. Here, the steel wire 47 includes high carbon steel such as a so-called piano wire. When strength is required as the connecting member, a sheet metal or the like can be used instead of the steel wire 47. Further, the component holder 46 is made of resin and is formed according to the bottom shape of the component 2 to be transported, but the material, shape, size, etc. can be appropriately changed according to the component type, for example, In addition to such a trapezoidal holder, a holder that can be moved up and down while the component 2 is housed in a cage, or a holder that can be moved up and down while hooked with a wire, etc. it can. Furthermore, in the present embodiment, a component discharge port lid 49 is provided in the middle of the two steel wires 47 (see FIG. 3 and the like). The component discharge port lid 49 is provided for each of the tanks 3 to 6 when the component 2 is immersed in the chlorofluorocarbon solvent in the cleaning tanks 3 to 5 or positioned in the drying tank 6 (that is, the component discharge port). It is for covering the tanks 3 to 6 and is installed at a size and height. For example, when the cleaning tanks 3 to 5 are covered with the component discharge port lid 49 during cleaning, the recovery efficiency of the fluorocarbon solvent can be improved. As described above, in the component conveying device 9 of the present embodiment, the component holding component 45 can be attached to and detached from the bridge 44 by the mounting member 48, so that the type of the component 2 or the depth of each of the tanks 3 to 6 is determined. It can be replaced with a component holding component 45 having different specifications such as a holder shape and height according to conditions.

  The raising / lowering driving device 11 is a device for raising and lowering the component conveying device 9 composed of the upper and lower guide shafts 42, 43 and the like, and includes a component vertical motor 53, a timing belt 54, and the like (see FIG. 21 and the like). In the present embodiment, a geared motor placed horizontally on the vertical guide bearing portion 50 is used as the component vertical motor 53. The timing belt 54 is stretched in the vertical direction by attaching belt ends to upper and lower brackets 55 and 56 provided in the vicinity of the upper and lower ends of the upper and lower guide shafts 42 and 43, and part of the timing belt 54 is part vertical motor 53. It is in the state wound around the pulley 57 of the rotating shaft (see FIG. 20 etc.). Further, auxiliary pulleys 58 and 59 are provided above and below the pulley 57 to stretch the timing belt 54 in a V shape and increase the amount of winding around the pulley 57. According to the elevating drive device 11 described above, the rotational driving force of the component vertical motor 53 is transmitted in the order of the motor 53 → the pulley 57 → the timing belt 54, whereby the timing belt 54, the brackets 55 and 56, the bridge 44, and the vertical guide. The shafts 42 and 43, the component holding component 45, etc. move up and down integrally.

  In addition, it is also preferable to position the horizontal position of the component discharge port lid 49 by the positioning member 60 only when the component is at the rising end (see FIG. 10 and the like). In such a case, the horizontal positioning reproducibility at the rising end of the component 2 is ensured, and the component holding component 45 is fixed when the component 2 is attached or detached, so that the operation is facilitated. In this embodiment, a positioning pin 49 a is provided on the upper part of the component discharge port lid 49, and the horizontal position of the positioning pin 49 a and thus the component discharge port lid 49 is positioned using a through hole provided in the positioning member 60. (See FIG. 24 and the like).

  Next, the cooler 8 will be described. The cooler 8 is a device that condenses and collects the vapor of the chlorofluorocarbon solvent, and includes a cooling pipe 61, a collecting plate 62, a Peltier element 64, and the like (see FIG. 4 and the like).

  The cooling pipe 61 is a pipe provided above the tanks 3 to 6 for cooling and condensing the fluorocarbon solvent vapor. The cooling pipe 61 desirably has a long pipe length in terms of a normally open pipe that cools the steam, but when the cooling pipe 61 also serves as an introduction pipe for the part 2, it is desirable that the pipe length is short from the viewpoint of shortening the component moving distance. Therefore, in this embodiment, a pipe is constituted by the large-diameter and short-axis vertical circular holes 61a and the small-diameter and long-axis vertical holes 61b, and the fluorocarbon solvent vapor is condensed on the inner walls of these pipes (see FIG. 25). . The vertical circular hole 61a is formed in a size that allows the above-described component holder 46 to pass while holding the component 2. The cooling pipe 61 of the present embodiment includes a bearing hole 61c at the center thereof, and functions as a radial bearing of the hollow shaft 14 (see FIG. 4). In the present embodiment, the cooling device for cooling the cooling pipe 61 is constituted by a Peltier element 64, a heat sink 65, and a fan motor 66 (see FIG. 25).

  The collection plate 62 is a device that collects and collects a part of the fluorocarbon solvent cooled and condensed by the cooling pipe 61. For example, a funnel-shaped (inverted conical shape) that can be collected in the center is adopted, and a recovery hole in the center is used. The fluorocarbon solvent is provided from 62c to the liquid collection tray 22 disposed below (see FIG. 4). Through holes 62a and 62b having substantially the same diameter are provided at positions where the recovery plate 62 overlaps the vertical circular holes 61a and 61b described above. Around the through holes 62a and 62b, there are provided bank-like edges 62d for preventing the fluorocarbon solvent flowing along the inclined surface of the recovery plate 62 from flowing through the through holes 62a and 62b. . The recovery plate 62 is preferably formed of a material such as a resin so that heat transfer between the cooling pipe 61 and the cooling pipe 61 is prevented as much as possible, thereby further improving the heat insulation of the cooling pipe 61. Thus, the cooling efficiency can be increased. It is also preferable to interpose a heat insulating material 63 between the cooling pipe 61 and the recovery plate 62 in order to further improve the heat insulating property. In the present embodiment, the heat insulating material 63 is attached to the upper edge of the peripheral wall 67 of each of the tanks 3 to 6, the recovery plate 62 is attached to the lower portion of the heat insulating material 63, and the cooling pipe 61 is attached to the upper portion of the heat insulating material 63. Therefore, the loss of heat (cold heat) is reduced (see FIG. 4). As the heat insulating material 63, a plastic material having heat insulating properties and having a fluorocarbon solvent resistance, such as PTFE resin (polytetrafluoroethylene), epoxy resin, POM resin (polyoxymethylene), or polyacetal resin is suitable.

  According to the cooler 8 having the above-described configuration, the chlorofluorocarbon solvent cooled and condensed on the inner wall of the cooling pipe 61 flows along the inner wall, drops onto the collecting plate 62, and further flows along the slope to collect the collecting hole. Drop from 62c down below. The fluorocarbon solvent further flows along the surfaces of the hollow shaft 14, the engagement block 37, the joint block 36, etc., and is returned to the final cleaning tank 5 by the liquid recovery dish 22 (see FIG. 4).

  Furthermore, the control apparatus 13 in the solvent cleaning apparatus 1 of this embodiment is demonstrated. The control device 13 is provided to detect the evaporation amount of the chlorofluorocarbon solvent based on the surface temperature of the cooler 8 and adjust the temperature of the heater 7 based on the detected amount. In the present embodiment, a liquefier temperature sensor 70 is provided on or near the surface of the cooling pipe 61 (see FIG. 12), and the temperature near the surface of the cooling pipe 61 is detected by this sensor 70. That is, when the amount of chlorofluorocarbon solvent evaporation is large, the amount of heat exchange and liquefaction increases and the surface temperature rises. On the other hand, when the amount of chlorofluorocarbon solvent evaporation is not large, the amount of heat exchange and Since the liquefaction amount does not increase so much and the surface temperature remains low, the evaporation amount of the chlorofluorocarbon solvent in the cooler 8 is detected based on the measured surface temperature value and its change. Further, the temperature of the Peltier element 64 is detected by a cooler heat radiation part temperature sensor 71 provided in the Peltier element 64 (see FIG. 12). The cooler heat radiating portion temperature sensor 71 functions as a sensor that can detect malfunctions and failures of the cooler 8 based on the detected temperature. The liquefaction part temperature sensor 70 and the cooler heat radiation part temperature sensor 71 are both connected to the CPU 72 (see FIG. 12). The CPU 72 controls the temperature of the heater 7 through a heater temperature controller 73 and an SSR (solid state relay) 74 based on information detected by the sensors 70 and 71. That is, when the evaporation amount of the fluorocarbon solvent is too large, the temperature of the heater 7 is lowered to suppress the evaporation amount. On the other hand, when the evaporation amount is small, the temperature of the heater 7 is increased as necessary to reduce the evaporation amount. increase. As a result of the temperature control as described above, the solvent cleaning apparatus 1 has evaporated the amount of the chlorofluorocarbon-based solvent that exceeds the condensing capacity of the cooler 8, or the condition in which only a very small amount of the chlorofluorocarbon solvent has evaporated compared to the condensing capacity Therefore, it is possible to achieve a situation in which an appropriate amount of the chlorofluorocarbon solvent is always distilled and refined by balancing the evaporation amount and the condensation amount. Moreover, according to this, since the amount of CFC-based solvent corresponding to the cooling capacity of the cooler 8 can be stably purified, it contributes to energy saving of the entire solvent cleaning device 1. Furthermore, the solvent cleaning apparatus of this embodiment that detects the evaporation amount based on the surface temperature of the heater 7 even when the evaporation amount of the chlorofluorocarbon solvent increases due to the heat generated by the ultrasonic vibrator 21 or the outside air temperature. According to 1, since the detection sensitivity is high and the time until the response of stopping the heater 7 is short, the outflow of the fluorocarbon solvent to the outside can be prevented.

  Furthermore, the other structure of the control apparatus 13 and its circuit structure are demonstrated below (refer FIG. 3, FIG. 12). The CPU 72 is connected to motor drivers 75 and 76 of the cleaning tank rotating motor 23 and the component up / down motor 53, respectively. Further, the origin sensor 28a and the index sensor 28b constituting the rotation sensor 28, and the rising end sensor 52a, the intermediate position sensor 52b and the falling end sensor 52c constituting the vertical sensor 52 are connected to the CPU 72. The Peltier element 64 and the fan motor 66 are driven by a pulse width modulated signal. A temperature sensor 77 that detects the temperature of the liquid in the drain tank 17 and further prevents emptying in the tank is connected to the heater temperature controller 73 described above. The temperature sensor 77 and the ultrasonic oscillator 78 that oscillates ultrasonic waves to the ultrasonic transducer 21 are connected to the power supply device 79 and the CPU 72, respectively. In addition, a communication interface 80, a communication HMI (Human Machine Interface) 81, a display device 82 such as an LED or an LCD, and a nonvolatile memory 83 are connected to the CPU 72. The nonvolatile memory 83 stores an operation program, a temperature control value, and the like.

  Further, in this embodiment, a gantry 84 is provided by combining a bracket-like frame or plate material, the solvent cleaning device 1 is provided thereon, and the above-described various control devices are arranged in the gantry 84 ( (See FIG. 3). Specifically, a heater temperature controller 73, an ultrasonic oscillator 78, a switch box (reference numeral 85a is a switch) 85, and the like are arranged on the top or bottom of the base plate 84. The gantry 84 is provided with a detachable connector 86 for connecting various devices of the solvent cleaning device 1. The connector 86 is detached when the upper side of the solvent cleaning device 1 is removed from the lower control device 13 side or attached to the control device 13 side.

  Subsequently, a structure in which a part of the inside of the solvent cleaning apparatus 1 is visible will be described below. In the solvent cleaning apparatus 1 of the present embodiment, a visual recognition window 69 is provided on the peripheral wall 67, and it is possible to confirm by looking inside the apparatus 1 through the visual recognition window 69. As a result, in this solvent cleaning apparatus 1, the operator or the administrator confirms that the component 2 is held at a predetermined position on the component holder 46, and that each tank 3-6 rotates 90 degrees at a predetermined timing. That the parts 2 are immersed in each of the tanks 3 to 5 and that the amount of the chlorofluorocarbon solvent circulated is within an appropriate range. . Moreover, since the visual recognition window 69 is provided on the peripheral wall 67, it is easier to grasp the situation in the rotary cleaning tank or the like than when looking through the upper opening of the cooling pipe 61, for example. In the present embodiment, a glass plate is used as the visual recognition window 69, but an acrylic plate or the like can also be adopted.

  Further, in the solvent cleaning device 1, at least one of the rotation driving device 10 and the lifting / lowering driving device 11 is disposed above the cleaning tanks 3 to 5, and the cleaning tank 3 to the rotation driving device 10 and the lifting / lowering driving device 11 are arranged. The thing arrange | positioned above 5 can be attached or detached with respect to the washing tanks 3-5. Hereinafter, the attachment / detachment structure of the solvent cleaning apparatus 1 of the present embodiment that is detachable as described above will be described.

  In the present embodiment, both the rotary drive device 10 and the lift drive device 11 are arranged above the cleaning tanks 3 to 5 (and the drying tank 6) (see FIG. 3). Here, “arranged upward” includes not only the case of being arranged right above the tank but also the case of being arranged at a position higher than the washing tanks 3 to 5. In this embodiment, the peripheral wall surrounding each of the tanks 3 to 6 and the drain tank 17 is separated into the upper peripheral wall 67 and the lower peripheral wall 87 described above, and the upper portion can be removed from the peripheral wall 67 for rotation. The drive device 10 and the lift drive device 11 can be attached to and detached from the cleaning tanks 3 to 5 (and the drying tank 6 and the drain tank 17) (see FIG. 4). Specifically, the peripheral wall 67 and the peripheral wall 87 have the same diameter, the upper edge of the drain tank 17 has a flange shape that can be sandwiched between the peripheral walls 67, 87, and a plurality of attachments / detachments provided around the peripheral walls. These peripheral walls 67 and 87 can be integrated using the member 88 (refer FIG. 16 etc.). The detachable member 88 is preferably one that can reliably integrate the peripheral walls 67 and 87 and can be easily attached and detached. In this embodiment, a buckle device with a spring as shown in the figure is used as the attaching / detaching member 88, but other devices such as a clasp (hasp), a latch lock, a hose band, etc. may be used. Furthermore, in addition to these mechanical devices, a magnet type that can be attached and detached using magnetic force may be used. As an example of the magnet type, a magnet 89 is provided opposite to the lower end of the shaft 14 (or 15) and the center of the rotating disk 30, and the upper and lower portions of the solvent cleaning device 1 are attracted by attracting the two magnets 89 to each other. (See FIGS. 26 and 27).

  Note that the cleaning chlorofluorocarbon solvent has a small surface area and tends to swell or deteriorate the rubber sealing material. In order to attach and detach the peripheral walls 67 and 87, it is necessary to have a sealing effect that does not allow the fluorocarbon solvent to leak to the outside. The sealing material is preferably an O-ring, a rubber plate, a PTFE sealing material, etc. using fluorocarbon, EPDM (ethylene / propylene rubber), etc., which are highly resistant to fluorocarbon solvents. Further, the attachment / detachment position of the sealing material is preferably the upper part so as not to be directly exposed to the chlorofluorocarbon solvent in order to obtain a high sealing effect. In addition, it is preferable that a shaping | molding surface like an O-ring exists in the whole surface periphery. In the case of an elastomer such as PTFE, it is preferable that the pores on the porous surface are closed by coating on the side in contact with the liquid.

  As described above, according to the cleaning device 1 in which the rotation driving device 10 and the elevation driving device 11 are detachable, there is an advantage that maintenance of each component is facilitated. That is, since the rotary drive device 10 or the lift drive device 11 can be subjected to maintenance work such as inspection / maintenance after being removed from the apparatus main body, disassembly and the like are easy to perform and the degree of freedom of work is high. Further, if the upper part is removed from the peripheral wall 67, the cleaning tanks 3 to 5, the drying tank 6, and the drain tank 17 can be easily cleaned or removed from the gantry 84. .

  The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention. For example, in this embodiment, both the rotary drive device 10 and the lift drive device 11 are arranged above the cleaning tanks 3 to 5 and the both apparatuses 10 and 11 are detachable from the cleaning tanks 3 to 5 so-called tank rotation type. Although the upper-bottom-type rotation transmission type solvent cleaning apparatus 1 has been described, the present invention is not particularly limited to such a structure. At least one of the both apparatuses 10 and 11 is disposed above the cleaning tanks 3 to 5 and the apparatus. If 10 (or the apparatus 11) has a structure that can be attached to and detached from the cleaning tanks 3 to 5, work such as maintenance can be facilitated. Below, only the raising / lowering drive device 11 is arrange | positioned above the washing tanks 3-5 (and drying tank 6), and the rotation drive apparatus 10 is the tank rotation type lower part rotation transmission arrange | positioned below the washing tanks 3-5 etc. The solvent cleaning apparatus 1 of the formula will be described (see FIG. 28).

  The solvent cleaning apparatus 1 shown in FIG. 28 rotates the cleaning tanks 3 to 5 by a cleaning tank rotating motor 23 disposed below the cleaning tanks 3 to 5. The cleaning tank rotating motor 23 has a rotating shaft 23 a. It is placed vertically so as to coincide with the rotation center of the rotary washing tank. Although not specifically shown in FIG. 28, the configuration of each device such as the lifting drive device 11, each of the tanks 3 to 6, the heater 7, the cooler 8, and the component transfer device 9 is particularly different from that of the solvent cleaning device 1 described above. There is no place. In the solvent cleaning apparatus 1, since the upper side including the lifting drive device 11 can be removed, maintenance of each device including the lifting drive device 11 can be easily performed.

  Here, if the structure of each type of the solvent washing | cleaning apparatus 1 mentioned above is shown with a schematic diagram, it will become like FIG. 29, FIG. Each of these solvent cleaning apparatuses 1 moves the component 2 up and down only on one vertical track, and advances the cleaning process by sequentially rotating the rotary cleaning tank in accordance with the lifting operation. In order to sequentially immerse in the cleaning tanks 3 to 5 (and the drying tank 6), it is only necessary to relatively rotate one of the component conveying device 9 and the cleaning tanks 3 to 5 (and the drying tank 6). Therefore, it is good also as a structure opposite to the solvent washing | cleaning apparatus 1 of this embodiment, ie, the structure which rotates the component holder 46 etc. of the component conveyance apparatus 9 instead of rotating each tank 3-6. For example, the solvent cleaning apparatus 1 whose outline is shown in FIG. 31 sequentially advances the cleaning process of each component 2 by rotating a single or a plurality of component holders 46 in the component conveying device 9 with a rotary motor 23 ′. As shown in the example here, it is eventually possible to perform automatic cleaning by relatively rotating any one of the component conveying device 9 and the cleaning tanks 3 to 5 (and the drying tank 6). is there. In FIGS. 29 to 31, the cleaning tanks are indicated by reference numerals 3 and 4, but this is only for convenience and does not mean that other cleaning tanks or drying tanks are excluded.

  As shown in FIG. 1, the solvent cleaning apparatus 1 is accommodated in a predetermined portion of the case main body 111, and the container 102, for example, four Freon solvent containers, and a power supply 121, a parts box 122, a funnel 123, a dropper 124 and the like are attached. The product 103 is accommodated in a predetermined location of the case main body 111. After the storage, the lid 112 is closed. Thus, since the solvent cleaning apparatus 1, the container 102, and the accessory 103 are accommodated in the portable case 101, the solvent cleaning apparatus 1 can be easily carried to any place.

  Therefore, since the cleaning apparatus set 100 of the present invention can be lent to, for example, a laboratory in a university, a laboratory in a company, or the like, accurate cleaning evaluation can be easily performed at an arbitrary location.

  Further, since the container 102 and the accessory 103 are housed in the portable case 100 in addition to the solvent cleaning device 1, a cleaning test can be performed without preparing the container 102 and the accessory separately. Easy cleaning evaluation.

  At this time, the container 102 is a chlorofluorocarbon solvent container, and it is not necessary to prepare a chlorofluorocarbon solvent separately. That is, if only the article to be cleaned is prepared, a cleaning test can be performed. Easy cleaning evaluation. In particular, chlorofluorocarbon solvents are usually not sold in small quantities that can perform cleaning tests, that is, they are not sold unless they are high in quantity. Can be done easily.

  Also, by storing two or more chlorofluorocarbon solvent containers containing different types of chlorofluorocarbon solvents in the case 101, it is compared which cleaning agent is suitable for cleaning the target object to be cleaned. Therefore, it is possible to easily grasp the fluorocarbon solvent suitable for the target object to be cleaned.

  In addition, the fluorocarbon solvent that contributed to the cleaning of parts and the like to be cleaned is collected in a fluorocarbon solvent container, and the borrower of the cleaning device set 100 of the present invention performs post-treatment of the fluorocarbon cleaning agent. Since it is not necessary to do so, cleaning evaluation can be easily performed.
