The present invention relates to a cleaning apparatus and method, and more particularly, to a cleaning apparatus and method configured to effectively remove contaminants present on the adhesive surface of the sole of a shoe during a shoe manufacturing process.

In general, the shoe manufacturing process can be roughly divided into two, one for making the upper skin of the shoe, or upper, and the other for making the sole of the shoe, i.e. the sole.

The upper and the sole thus made are finally assembled through an adhesive process to form the final shoe. In this bonding process, the cleanliness of the bonding surface is very important. That is, when a large amount of contaminants on the surface of the adhesive surface, the adhesive strength is lowered and desorption occurs eventually, which acts as a fatal defect in the durability, which is the most important characteristic of the shoe. To prevent this, a cleaning operation must be performed prior to the bonding process to remove contaminants present on the adhesive side of the sole.

In addition, in the manufacture of the sole, various forms of heterogeneous parts or dissimilar materials (for example, rubber, pylon, polyurethane, etc.) such as airbags are made by assembling through an adhesive process, wherein In order to achieve sufficient adhesive strength, the cleaning process on the part surface must be carried out before the bonding process.

In this way, in the bonding process, which is a key step in the shoe manufacturing process, the cleaning operation for effectively removing contaminants present on the bonding surface is a very important process for obtaining sufficient adhesive strength.

Conventionally, the chemical wet cleaning method was used as a method of washing a sole in a shoe manufacturing process. This chemical wet scrubbing method is usually performed by mixing a strong acid or a strong base solution with water and spraying with high pressure in the form of a spray. In addition, a strong organic solvent (eg, methyl ethyl ketone (methylethylketone) solvent) may be used to rub the worker directly. This conventional cleaning method generates a large amount of waste water by using toxic chemicals, costs a large amount of money due to continuous use of consumable chemicals and treatment of generated waste water, and exposes workers to harmful working environments. Since the chemical cleaning requires a rinsing and drying process, the cleaning time is long and the cleaning apparatus is very large.

Accordingly, the present invention is to solve the problems of the prior art, it is possible to effectively remove the contaminants on the sole surface of the shoe sole quickly and environmentally friendly at a low cost without generating any waste water in the shoe manufacturing process It is an object of the present invention to provide a cleaning apparatus and method capable of making the size small.

In order to achieve the above object, the cleaning device of the present invention is a cleaning device for removing contaminants of a cleaning work, and is equipped with a flash lamp for generating pulse wave flashing and flashes irradiating the pulsed work with the flashing light. It characterized in that it comprises a generator.

Moreover, the washing | cleaning method of this invention is characterized by irradiating a pulse wave flash to a cleaning workpiece, and removing the contaminant of a cleaning workpiece.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a schematic diagram of a cleaning apparatus according to an embodiment of the present invention. As shown, the cleaning apparatus according to this embodiment is a scintillation generator, a high voltage power supply, a cooler, a light monitor, a light shield, a conveyor, a workpiece detector, a high pressure gas injector as a cleaning apparatus for removing contaminants of a cleaning work. , Dust inhaler, controller.

The flash generator 10 is equipped with a flash lamp 11 for generating pulse wave flashes, and generates a strong pulse wave flash from the flash lamp 11 to irradiate the cleaning work W with pulse wave flashes for cleaning. The cleaning of the surface of the workpiece W is performed.

The flash generator 10 is connected to a high voltage power supply 20 to supply high voltage power to the flash generator 10.

The high voltage power supply 20 is a device for generating high voltage power to supply the flash lamp 11 to generate strong light from the flash lamp 11. This high voltage power supply 20 usually has a built-in simmer board and is designed to generate instantaneous high voltage. The intensity of the flash increases in proportion to the magnitude of the applied voltage, which in turn improves the cleaning performance. Therefore, as the high voltage power supply 20 used in the present invention, it is preferable to use the one designed to supply the voltage of 500 V or more per lamp, and more preferably the one designed to supply the voltage of 1000 V or more.

When the flash lamp 11 is turned on by receiving the high voltage power from the high voltage power supply 20, a strong flash is instantaneously generated, and the generated flash is irradiated onto the surface of the work W to perform cleaning. The flash lamp 11 usually generates light by applying a momentary high voltage of 500 V or more, and preferably a xenon (Ze) lamp is preferable. At this time, the generated light includes a lot of wavelength bands in the ultraviolet region, which triggers photochemical decomposition of organic pollutants by ultraviolet rays, thereby effectively performing cleaning.

Generally, ultraviolet lamps require a lot of time for cleaning by continuously generating low power density light in the form of a continuous wave like a fluorescent lamp, but the light generated by the flash lamp as in the present invention is a pulse wave. In the form of pulse waves, it instantly emits very high power densities, enabling faster and more effective cleaning of contaminants.

Since the pulse wave flash generated by such a flash lamp is effective for oscillating a powerful laser beam having a strong and instantaneous power density characteristic, the flash lamp is also used for fabricating a laser oscillator.

On the other hand, when the light is emitted by the flash lamp, a very large amount of heat is generated together due to the characteristics of the flash lamp which instantaneously generate a strong power density. Accumulation of generated heat deteriorates the performance of the flash lamp and ultimately reduces the lifespan. Therefore, effective cooling of the flash lamp is very important. In the present invention, the cooling water flows around the flash lamp in order to effectively cool the heat of the flash lamp, thereby preventing the deterioration of the service life and performance due to the temperature increase of the lamp.

2 and 3 are shown in more detail with respect to the flash generator of the cleaning apparatus according to an embodiment of the present invention.

The flash lamp 11 is supported by the support 13. The support 13 is a hollow body having an open portion facing the cleaning workpiece W, and flashes in a shape corresponding to the shape of the flash lamp 11 so that the flash lamp 11 can be spaced apart therein. It is formed larger than the size of the lamp 11. In the present embodiment, the support 13 has a lower side, and is formed long in the longitudinal direction as the flash lamp 11 has a rod shape, and supports the flash lamp 11 by inserting and supporting the flash lamp 11 at both ends. It is illustrated that the hole 13a is formed. The support hole 13a is positioned so that the light emitting portion 11b of the flash lamp 11 does not touch the inner wall of the support 13 when the electrode portion 11a of the flash lamp 11 is inserted and supported therein. have.

In order to allow the cooling water to flow around the flash lamp 11, the pulse wave flash should be irradiated to the cleaning work W while sealingly surrounding the light emitting portion 11b of the flash lamp 11. In the present embodiment, the sealing portion 14 seals between the boundary portion of the electrode portion 11a and the light emitting portion 11b of the flash lamp 11 and the support hole 13a of the support 13, and the support 13. The transparent window 15 is provided in the part facing the washing | cleaning workpiece | work W of this, ie, the open lower part. The transparent window 15 and the support 13 are sealed with a sealing material 18.

As the sealing material, it is preferable to use O-ring, Teflon tape or epoxy and silicone resin.

The sealed support body 13 and the transparent window 15 form a sealed chamber around the flash lamp 11. Cooling water is supplied and circulated inside the sealing chamber, and inlets 13b and outlets 13c are formed at both ends of the support 13, respectively, and a cooler 30 is provided at the inlets 13b and the outlets 13c. It is connected.

Since the transparent window 15 should irradiate the workpiece | work W to the light which generate | occur | produces effectively from the flash lamp 11, it is preferable to use quartz which has a good transmittance at all wavelengths as a material. The transparent window 17 also serves to protect the interior of the flash generator 10 from contaminating dust.

The cooler 30 is preferably a water cooled circulation pump cooler for effective cooling. In addition, when using general water as the water used for cooling may cause problems such as leakage of current and contamination of the flash lamp, it is preferable to use distilled water or ultra pure water (Deionized water) to solve this problem. The temperature of cooling water is suitable if it is between 20-30 degrees.

As a material of the support body 13, it is preferable that it is a stainless-type material which does not produce rust.

In the flash generator 10, a light reflection plate 17 is provided inside the flash lamp 11. This light reflection plate 17 concentrates and directs the pulsed wave flashes generated by the flash lamp 11 to the cleaning work W. As shown in FIG. The shape of the light reflection plate 17 is made of a semi-elliptic shape, the elliptic curvature may be set to a value for effectively transmitting light in the direction of the workpiece in accordance with the installation conditions. In the present embodiment, the intermediate inner wall of the support 13 of the flash generator 10 is formed in a semi-elliptic shape, and the semi-elliptic light reflecting plate 17 is attached to the inner wall of the support 113.

As a material of a light reflection board, gold, silver, or a ceramic which has good reflectivity in all wavelength bands is preferable. On the other hand, this light reflector can also be manufactured by coating a reflective material inside the scintillation generator.

In addition, although not illustrated in the drawings, the flash generator may be equipped with a manual or automatic elevator capable of varying the height of the device, thereby minimizing the change in the cleaning performance according to the height change of the cleaning work.

In the flash generator 10, a pinhole 19 is formed inside the flash lamp 11. An optical monitor 40 is connected to the pinhole 19. The pinhole 19 is formed through the light reflection plate 15 and the support 13.

The optical monitor 40 performs the measurement of the intensity of light generated by the flash lamp 11 in real time. The flash lamp 11 has a specific lifetime due to the characteristics of the lamp, and the light intensity gradually decreases with time. Since the cleaning performance is proportional to the light intensity, measuring the light intensity in real time is very important for stable cleaning operation. In order to measure the intensity of light, a light sensor is mounted near the flash generator to measure the intensity of light in real time, and the amount of change over time is checked at a controller from time to time. If the measured value falls below the reference value for smooth cleaning, the controller automatically raises the level of the voltage supplied from the high voltage power supply, or sends a signal to the operator to automatically notify the abnormality. As a light sensor, a photodiode can be used, and an optical filter that can select light of a specific wavelength can be installed in front of the light sensor for accurate detection.

As shown, an optical monitor 40 for measuring the intensity of light generated by the flash lamp 11 is attached to the flash generator 10, and the pinhole 19 is drilled in the flash generator 10 to pinhole. By using the method of sensing the light emitted from the optical monitor 40 by 19, since the light emitted from the flash lamp 11 is measured directly, it is possible to minimize the change in the intensity of light due to the external environment Therefore, there is an advantage that optical monitoring can be precise and reliable.

In addition, an upper portion of the flash generator 10 is provided with a light shielding portion 50 for preventing the exposure of the pulse wave flash generated by the flash lamp 11 to the operator.

The light shield 50 is a device for maximally reducing the external emission of the strong flash generated in the flash generator 10 during the cleaning process. The intensity of the flash generated by the flash lamp 11 is very strong, and when the worker sees it directly, eye fatigue occurs. Therefore, the installation of the device to shield the flash is very important for ensuring a comfortable working environment. The light shield 50 may be manufactured in the form of a case using an opaque metal material and mounted on an upper portion of the flash generator 10, and may be manufactured by attaching a light absorbing material that effectively absorbs light to the inner surface of the case.

In addition, a conveyor 60 for continuously transporting the cleaning workpiece W may be installed at the lower portion of the flash generator 10.

Conveyor 60 is preferably to use a belt conveyor type, the shape of the belt may use a mesh (mesh) shape to prevent any slip of the workpiece may be. It is desirable to manufacture the belt so that the moving speed can be varied so that the cleaning speed can be changed according to the cleaning workpiece.

In addition, a job for detecting a workpiece introduced for cleaning on the path before cleaning of the cleaning workpiece W in the flash generator 10 in the transport path of the cleaning workpiece W conveyed by the conveyor 60. The water detector 70 is installed.

When the workpiece W detects the movement of the workpiece W to the flash generator through the workpiece detector 70, cleaning is performed by automatically starting the operation of the flash lamp 11 and the cooler 30. Such workpiece detector 70 can minimize the operating time of the flash lamp 11, through which there is an advantage that can maximize the life of the flash lamp (11). As the workpiece detector 70, a laser sensor or a proximity optical sensor can be used.

In addition, in the transfer path of the cleaning workpiece (W) conveyed by the conveyor 60, floating between the workpiece detector 70 and the flash generator 10 in the workpiece before cleaning by the flash generator 10 A high pressure gas injector 80 for removing contaminant particles is installed.

The high pressure gas injector 80 is used to remove suspended inorganic contaminant particles present on the cleaning surface when the workpiece W is introduced through the conveyor. The contaminants that can be effectively removed by the flash lamp 11 are organic contaminants, usually oily, and inorganic contaminants are difficult to remove. Accordingly, the floating inorganic material is sprayed by spraying the high-pressure gas supplied from the gas supply part 81 to the surface of the workpiece W through the gas injection nozzle 83 before the workpiece W approaches the flash lamp 11. It can effectively remove contaminants.

At this time, general compressed air may be used as the kind of gas, and an inert gas such as nitrogen may be used. The angle of the gas injection nozzle 83 is important in the precleaning of the workpiece W by the high pressure gas injection, preferably 30 to 70 °.
