Description

Cleaning device with transfer automation applied {Apparatus for UV cleaning with transfer automation}

The present invention relates to a cleaning apparatus to which transport automation is applied, and more particularly, to perform cleaning by irradiating an ultraviolet ray to a material to be cleaned that passes through a cleaning area formed inside a chamber, and passes through a carry-in area, a cleaning area, and a take-out area in sequence. The present invention relates to a cleaning apparatus to which transport automation is applied in which an object to be cleaned passes through the cleaning area by opening and closing the opening and closing part when the object to be transported approaches the cleaning area and close to the carrying area.

In recent years, as interest in personal hygiene is increasing, research and development of ultraviolet (UV) sterilizers are being actively carried out. Personal belongings related to personal hygiene management include cell phones, toys, and portable medical devices. Among them, cell phones are the most contacted objects throughout the day and require sterilization due to their high degree of contamination. Moreover, in the case of mobile phones, it is necessary to periodically sterilize them in consideration of bacterial growth and infection.

As a personal belongings sterilizer according to the prior art, a storage-type UV sterilizer that emits UV light using a mercury lamp is widely used. Such a conventional ultraviolet sterilizer sterilizes items using ultraviolet rays emitted from a mercury lamp, which is a light source, in a box-type storage box.

In addition, other conventional UV sterilizers have weak sterilization power and thus have inefficiency problems such as sterilization for a long period of time, for example, for several tens of minutes to several hours.

Since other conventional UV sterilizers require a warm-up time of about 10 minutes to 1 hour to obtain light energy above a certain value, it is difficult to immediately sterilize the conveyed material being loaded onto the conveyor.

Recently, LED (Light Emitting Diode), LD (Laser Diode), etc. have been developed and are attracting attention as alternative light sources for mercury lamps. In particular, LED light sources are small in size and can be used without a warm-up time by selecting only a desired wavelength band, and have the advantage of having a lifespan of tens of thousands of hours and being eco-friendly.

However, there is a disadvantage in that the price of the LED emitting light in the ultraviolet band (250-280 nm) with excellent sterilization power is high. For example, the price of an LED that emits UV in the 405 nm band is considerably cheaper than that of a light source that emits UV in the 250-280 nm (UV-C) band, but the sterilization power is about 1,000 times weaker, so it mainly sterilizes things that can be sterilized for a long time. It is used as a light source for sterilizers.

As described above, the UV sterilizer using the LED light source according to the prior art has to emit UV light for several minutes to several hours due to insufficient light quantity, and it is difficult to uniformly sterilize it, so it is applied to a storage type sterilizer. In the case of a conventional UV sterilizer that uses an LED light source and is applied to a conveyor, it is implemented in a way that directly emits UV light to the object to be sterilized without going through an optical system, so there is a problem that the sterilization efficiency is lowered and UV rays harmful to the human body leak out.

Conversely, as shown in FIG. 5 , when the object P is not detected in the entrance area AR1 ′, the processor 160 controls the opening and closing unit 130 to close the first door unit 131 . can

Thereafter, when the object to be cleaned P is sensed in the cleaning area AR2 , the processor 160 may control the cleaning unit 140 to be irradiated with ultraviolet rays.

More specifically, when the object P is detected in the cleaning area AR2 , the processor 160 acquires surface area information of the object P facing the cleaning unit 140 , and the surface area information Based on the , target UV irradiation amount information corresponding to the object P may be calculated.

In this case, the processor 160 may set the target UV dose information as the target UV dose information indicated by the target UV dose information increases as the surface area indicated by the surface area information increases.

That is, the processor 160 may calculate the target UV dose information by using the target UV dose per unit surface area. Specifically, the processor 160 may calculate the target UV dose information by applying the target UV dose per unit surface area to the surface area indicated by the plane area information.

Meanwhile, according to another exemplary embodiment, the processor 160 may identify the target UV dose corresponding to the surface area information of the object to be cleaned P with reference to reference data to which the target UV dose for each surface area is mapped.

Thereafter, the processor 160 performs the cleaning unit such that the amount of UV irradiated to the object P is irradiated to the target object P while the object P passes through the cleaning area AR2 to reach the target UV dose indicated by the target UV dose information. At least one of the separation distance between 140 and the object P to be cleaned, the light intensity of ultraviolet rays irradiated from the cleaning unit 140 and the transport speed of the object P to be cleaned may be controlled.

The processor 160 may control the cleaning unit 140 so that the separation distance between the cleaning unit 140 and the object P becomes shorter as the target UV irradiation amount indicated by the target UV irradiation amount information increases.

In addition, the processor 160 may control the cleaning unit 140 so that the light intensity of the ultraviolet rays irradiated from the cleaning unit 140 increases as the target UV irradiation amount indicated by the target UV irradiation amount information increases.

In addition, the processor 160 may control the transfer unit 110 so that the transfer speed of the object P to be cleaned becomes slower as the target ultraviolet irradiation amount indicated by the target ultraviolet irradiation amount information increases.

Specifically, when the object to be cleaned (P) enters the cleaning area (AR2), the processor 160 controls the current transfer speed of the object to be cleaned (P) and the cleaning unit (140) to be cleaned with the object (P). While the object to be cleaned (P) passes through the cleaning area (AR2) based on the minimum separation distance that the cleaning unit 140 can maintain and the light intensity of the ultraviolet rays irradiated from the cleaning unit 140, the object to be cleaned ( It is possible to calculate the predicted UV irradiation amount of the UV to be irradiated to P).

For example, when the predicted UV irradiation amount is less than the target UV irradiation amount, the processor 160 determines that the transport speed of the object P is reduced and the light intensity of the UV irradiated from the cleaning unit 140 is increased. It is possible to calculate the predicted UV irradiation amount by assuming .

When the predicted UV irradiation amount is smaller than the target UV irradiation amount, the processor 160 predicts a situation in which the transport speed of the object P is reduced and a situation in which the light intensity of the UV irradiated from the cleaning unit 140 is increased. The amount of ultraviolet irradiation can be calculated.

The processor 160 controls the transfer unit 110 and the cleaning unit 140 so that, when the predicted ultraviolet irradiation amount is the same as the target ultraviolet irradiation amount, the transport speed of the object to be cleaned P and the light intensity of the ultraviolet rays are maintained in the assumed situation. can do.

For another example, when the predicted UV irradiation amount is greater than the target UV irradiation amount, the processor 160 determines that the transport speed of the object P is increased and the light intensity of the UV irradiated from the cleaning unit 140 is reduced. Assuming the situation, the predicted UV irradiation amount can be calculated.

The processor 160 controls the transfer unit 110 and the cleaning unit 140 so that, when the predicted ultraviolet irradiation amount is the same as the target ultraviolet irradiation amount, the transport speed of the object to be cleaned P and the light intensity of the ultraviolet rays are maintained in the assumed situation. can do.

On the other hand, as shown in FIG. 6 , the processor 160 detects the object P in the exit area AR3 ′ adjacent to the take-out area AR3 among the cleaning areas AR2, the second door unit ( The opening/closing unit 130 may be controlled so that the 132 is opened. Conversely, as shown in FIG. 7 , when the object P is not detected in the exit area AR3 ′, the processor 160 controls the opening and closing unit 130 to open the second door unit 132 . can

Through this, the processor 160 minimizes the leakage of ultraviolet rays, ozone, and other harmful gases into the chamber 120 and at the same time generates the maximum cleaning effect. ) can be controlled.

Meanwhile, the processor 160 according to another embodiment is configured to change the light intensity of the ultraviolet ray irradiated from the cleaning unit 140 based on the opening degree information of the first door unit 131 and the second door unit 132 . The government 140 can be controlled.

Here, the opening degree information may be information indicating an open state of each of the first door unit 131 and the second door unit 132 , and the opening degree may be expressed as any one of 0% to 100%. . For example, if the opening degree information of each of the first door part 131 and the second door part 132 is 0%, it means that the first door part 131 and the second door part 132 are closed. , when the opening degree information of each of the first door part 131 and the second door part 132 is 100%, the first door part 131 and the second door part 132 are opened in the maximum open state that can be opened It could mean a state of being.

The processor 160 according to another embodiment is configured to reduce the light intensity of ultraviolet rays irradiated from the cleaning unit 140 as the opening degree indicated by the opening degree information of the first door part 131 and the second door part 132 increases. The cleaning unit 140 may be controlled.

Through this, it is possible to minimize the phenomenon that the first door part 131 and the second door part 132 are opened and the ultraviolet rays are leaked to the outside.
