Description

TECHNICAL FIELD The present invention relates to an ultraviolet irradiation conveying roller conveyor for irradiating ultraviolet rays while conveying an object to be conveyed, and an ultraviolet sterilization apparatus using the same.

In recent years, there has been a worldwide epidemic of a new type of viral disease, and measures to prevent the spread of harmful viruses, bacteria, etc. along with the transportation of goods are being studied in the transportation and logistics industries as well. As a device for sterilizing the surface of an object to be conveyed, such as a load, there has been proposed a device that irradiates the object to be conveyed with ultraviolet rays while the object is being conveyed on a conveyor or the like. However, with conventional UV sterilizers, it is difficult to irradiate the lower surface of the cargo that comes into contact with the conveying surface with UV rays, and in order to sterilize the entire surface of the cargo, it is necessary to change the direction of the cargo and irradiate the UV rays multiple times. there were.

As a conventional technique for dealing with such a problem, a technique has been proposed in which an ultraviolet lamp is arranged in a gap between rotating rollers constituting a roller conveyor and below the upper common tangent line of the rollers (see Patent Document 1). . However, in conventional roller conveyors, there is a space between the UV lamp and the package, and the adjacent rollers block a considerable amount of UV light, so many people need to use a lot of UV light to ensure sufficient irradiation for disinfection. It was necessary to place an ultraviolet lamp. Another problem is that the gap between the adjacent rollers becomes large due to the placement of the ultraviolet lamp.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and provides an ultraviolet irradiation conveying roller conveyor and an ultraviolet disinfection apparatus capable of effectively irradiating the bottom surface of an object to be conveyed with ultraviolet rays.

The ultraviolet irradiation conveying roller conveyor according to the present invention forms a conveying surface by arranging a plurality of rotating rollers along a predetermined direction,
An ultraviolet irradiation conveying roller conveyor that irradiates the object to be conveyed with ultraviolet rays while the object to be conveyed moves in the predetermined direction on the conveying surface,
At least one of the plurality of rotating rollers is replaced with a rod-shaped body having an ultraviolet irradiation section that generates ultraviolet C waves.

In such an ultraviolet irradiation conveying roller conveyor, since a rod-shaped body having an ultraviolet irradiation part is arranged at the position of the rotating roller that supports the object to be conveyed, the surface of the object to be conveyed is irradiated with ultraviolet C waves from a close distance. , the bottom surface of the object to be conveyed can be effectively sterilized. In addition, since at least one of the rotating rollers is replaced with a rod-shaped body, the distance between the rotating roller and the rod-shaped body and between the rotating rollers can be made narrower than in the conventional technology in which an ultraviolet lamp is arranged between the rollers. It can be transported smoothly.

Further, for example, the upper ends of the rod-shaped bodies may be aligned at substantially the same height as the conveying surface.

As a result, it is possible to effectively irradiate ultraviolet rays from a close distance, and since the rod-shaped portion also plays a role of supporting the object to be conveyed, it contributes to the smooth conveyance of the object to be conveyed.

Further, for example, a rod-shaped body cross section, which is a first cross-section parallel to the predetermined direction and perpendicular to the conveying surface of the rod-shaped body, is circular, and the diameter of the rod-shaped body cross section is equal to the diameter of the rotating roller. It may be substantially equal to the diameter of the roller cross-section, which is a cross-section by one cross-section.

In such an ultraviolet irradiation conveying roller conveyor, since the outer shape of the rod-shaped body is substantially equal to the outer shape of the rotating roller, the rod-shaped body can appropriately support the bottom surface of the object to be conveyed, and the object to be conveyed can be smoothly conveyed. To contribute.

Further, for example, both ends of the rod-shaped body are connected to side frames that support both ends of the plurality of rotating rollers,
The ultraviolet irradiation section may be non-rotatably fixed to the side frame.

By fixing the ultraviolet irradiation section so as not to rotate, the wiring structure to the ultraviolet irradiation section can be simplified, and the strength of the rod-shaped portion can be improved.

Further, for example, the ultraviolet irradiation section may extend inside the rod-shaped body along a direction parallel to the conveying surface and perpendicular to the predetermined direction.

By having such an ultraviolet irradiation section, it is possible to efficiently irradiate the entire bottom surface of the object to be conveyed, which faces the conveying surface, with ultraviolet rays.

Further, for example, the rod-shaped body includes an ultraviolet-transmitting protective portion that covers the conveying surface side of the ultraviolet irradiation portion, and an ultraviolet-impermeable lower portion that covers the opposite side of the ultraviolet irradiation portion from the conveying surface. and a cover portion.

By having such a protection part and a lower cover part, the rigidity of the rod-shaped body is improved, and external force can be prevented from acting on the ultraviolet irradiation part, thereby protecting the ultraviolet irradiation part from damage. In addition, the lower cover portion can prevent the ultraviolet rays from leaking to the installation surface side of the ultraviolet irradiation conveying roller conveyor.

Further, for example, the rod-shaped body may have an ultraviolet-transmitting rotary cover portion which is hollow cylindrical and is inserted by the ultraviolet irradiation portion and rotates relative to the ultraviolet irradiation portion.

By having such a rotating cover portion, the rigidity of the rod-shaped body is improved, and external force can be prevented from acting on the ultraviolet irradiation portion, thereby protecting the ultraviolet irradiation portion from damage. In addition, since the rotating cover rotates together with the transportation of the object to be transported, the object to be transported is prevented from being caught on the rod-shaped body, and external force is prevented from acting on the ultraviolet irradiating portion, and smoother transport is achieved. come true.

Further, for example, the ultraviolet irradiation conveying roller conveyor according to the present invention may have roller driving means for rotating the plurality of rotating rollers in a predetermined rotating direction.

The object to be conveyed can be automatically conveyed by rotating the rotating roller by the roller driving means. Examples of the roller driving means include those using a rotating motor and a chain or belt that transmits the driving force of the motor to the roller, those using a rotating motor, a drive shaft, a gear mechanism, and a motor built into the rotating roller. It is not particularly limited.

A second inner surface ultraviolet irradiation section for generating ultraviolet C waves is provided on a second inner surface of the second side wall portion, which is a surface on the conveying surface side.

Such an ultraviolet sterilization apparatus can efficiently irradiate the entire surface of the object to be conveyed with ultraviolet rays and effectively sterilize the surface of the object to be conveyed. In addition, although the bottom surface of the conveyed object is irradiated with ultraviolet light for a short time compared to the other surfaces, the bottom surface of the conveyed object is irradiated with the ultraviolet rays at a short distance from the rod-shaped ultraviolet irradiation part, so it can be exposed to the other surface in a short time. The same degree of sterilization as that of the surface can be performed. Moreover, such an ultraviolet sterilizer can prevent ultraviolet rays from leaking to the outside by the ultraviolet shielding portion.

Further, for example, a first connector may be provided on the entrance frame portion, which is one end of the ultraviolet shielding portion in the predetermined direction,
A second connector may be provided on the outlet frame portion, which is the other end portion in the predetermined direction of the ultraviolet shielding portion,
The first connector and the second connector may be connectable to each other.

Such an ultraviolet sterilization device can constitute an ultraviolet sterilization device with a long transport distance by connecting a plurality of ultraviolet shielding portions by connecting the first connection portion and the second connection portion.

Further, for example, the entrance frame portion may be detachably provided with an entrance shielding curtain for preventing leakage of ultraviolet rays from the entrance.

FIG. 5 is a cross-sectional view showing a roller section of a rotating roller and a rod-shaped body section of a rod-shaped body according to a modification.

FIG. 1 is an external view of an ultraviolet sterilization apparatus 10 having an ultraviolet irradiation conveying roller conveyor 20 (hereinafter simply referred to as conveying roller conveyor 20) according to one embodiment of the present invention. The ultraviolet sterilizer 10 includes a conveying roller conveyor 20, an ultraviolet shielding section 50, a ceiling ultraviolet irradiation section 41, a first inner ultraviolet irradiation section 62, a second inner ultraviolet irradiation section 63, and the like.

As shown in FIG. 1, the ultraviolet sterilization apparatus 10 can irradiate an object to be conveyed on the conveying surface 22 of the conveying roller conveyor 20 with ultraviolet rays to sterilize or sterilize the object to be conveyed. The object to be conveyed by the conveying roller conveyor 20 is not particularly limited, but examples thereof include packages packed with cardboard, suitcases, bags, industrial products before shipment, agricultural products, and the like.

FIG. 3 is a conceptual diagram of part of the transport roller conveyor 20 viewed from above. As shown in FIG. 3, the conveying roller conveyor 20 has a plurality of rotating rollers 24, 25, 26, . (see FIG. 4). In the description of the transport roller conveyor 20 and the ultraviolet sterilization device 10, the vertical direction is the Z direction, and among the horizontal directions, the arrangement direction of the plurality of rotating rollers 24, 25, 26 . The direction perpendicular to is defined as the Y direction.

The plurality of rotating rollers 24 , 25 , 26 are driven by roller driving means (not shown) to rotate in a predetermined rotating direction (see arrow 88 in FIG. 4 ), and the object to be conveyed on the conveying surface 22 is rotated by the rotating rollers 24 . , 25 and 26 (X direction). As the roller drive means, a rotating motor, a chain or belt for transmitting the driving force of the motor to the rotating rollers 24, 25, 26, a rotating motor, a drive shaft, or a gear mechanism, rotating rollers 24, 25, 26, but is not particularly limited.

1 and 3, at least one of the plurality of rotating rollers 24, 25, 26, . . Therefore, the transport roller conveyor 20 can irradiate the bottom surface of the object to be transported with ultraviolet rays while the object to be transported is moving on the transport surface 22 .

In the conveying roller conveyor 20 shown in FIGS. 1 and 3, 1/7 of the rotating rollers are replaced with the rod-shaped bodies 30, but the conveying roller conveyor 20 is not limited to this. In the conveying roller conveyor 20, for example, 1/2 to 1/10 rotating rollers may be replaced with rod-shaped bodies 30, or only one rotating roller may be replaced with rod-shaped bodies 30. However, as shown in FIGS. 1 and 3, the transport roller conveyor 20 preferably has at least two rod-shaped bodies 30 from the viewpoint of efficiently irradiating the object to be transported with ultraviolet rays. In addition, rotating rollers 24, 25, and 26 are provided on both sides of the rod-shaped body 30 in the transportation direction, except for the case where the rod-shaped body 30 is not arranged continuously in the transportation direction (X direction) and is at the end of the transportation roller conveyor 20. is preferably arranged in order to smoothly convey the object to be conveyed.

As shown in FIG. 3, both ends of the rod-shaped body 30 are connected to side frames 42 that support both ends of the plurality of rotating rollers 24, 25, and 26. As shown in FIG. The rod-shaped body 30 shown in FIG. 3 and the ultraviolet irradiation section 32 of the rod-shaped body 30 are fixed to the side frame 42 so as not to rotate. By fixing the rod-shaped body 30 to the side frame 42, the strength of the rod-shaped body 30 can be improved. Further, since the ultraviolet irradiation section 32 is fixed to the side frame 42, the wiring route to the ultraviolet irradiation section 32 that generates the ultraviolet C wave can be simplified.

However, the rod-shaped body 30 is not limited to one that is fixed to the side frame 42. For example, the rod-shaped body 30, like the rotating rollers 24, 25, and 26, is rotated by a roller driving means. A part of the rod-shaped body 130 may be rotatable like a rod-shaped body 130 (see FIG. 5) according to a modified example described later.

FIG. 4 is a cross-sectional view of the rod-shaped body 30 and the rollers 24, 25, 26 according to the first cross-section 22a shown in FIG. As shown in FIG. 4, a rod-shaped body cross section 30a, which is a cross section of the rod-shaped body 30 along the first cross section 22a (see FIG. 3), is circular, and the diameter of the rod-shaped body cross section 30a is equal to the first cross section of the rotating roller 24. Approximately equal to the diameter of the roller cross-section 24a, which is the cross-section through 22a. Therefore, as shown in FIGS. 3 and 4, the rod-shaped body 30 has a substantially cylindrical outer shape, which is similar to the rotary rollers 24, 25, and 26. As shown in FIG. However, the protective portion 34 and the lower cover portion 36, which will be described later, may be separated from the ultraviolet irradiation portion 32, and the bar-shaped portion 40 may have a shape other than a cylindrical shape.

As shown in FIG. 4, the upper end of the bar 30 is preferably flush with the conveying surface 22 (the upper common tangent line of the rotating rollers 25, 26 and 27). Such a rod-shaped body 30 can bring the ultraviolet irradiation section 32 close to the bottom surface of the object to be conveyed while supporting smooth conveyance of the object to be conveyed.

As shown in FIGS. 3 and 4, the ultraviolet irradiation section 32 extends inside the rod-shaped body 30 along the Y direction parallel to the conveying surface 22 and perpendicular to the conveying direction (X direction). . Since the ultraviolet irradiation section 32 extends in the Y-axis direction, the conveying roller conveyor 20 can irradiate the entire bottom surface of the object to be conveyed with ultraviolet rays. The ultraviolet irradiation unit 32 is not particularly limited as long as it irradiates electromagnetic waves containing ultraviolet C waves (wavelength 100 to 280 nm) that have a strong bactericidal effect, but examples include a special high-pressure mercury lamp and a UV-LED light source. .

As shown in FIG. 4, the rod-shaped body 30 includes a protective portion 34 covering the transport surface 22 side of the ultraviolet irradiation portion 32 and a lower cover portion covering the lower surface side of the ultraviolet irradiation portion 32 opposite to the transport surface 22. 36. The protective portion 34 is made of an ultraviolet-transmissive material such as transparent glass or transparent resin. On the other hand, the lower cover portion 36 is made of an ultraviolet-impermeable material such as metal.

The protective portion 34 and the lower cover portion 36 of the rod-shaped body 30 shown in FIG. 4 are fixed to the side frames 42, and the strength of the rod-shaped body 30 can be increased. Furthermore, if the lower cover portion 36 is made of metal, the effect of reinforcing the rod-shaped body 30 can be enhanced. Further, by forming the inner surface of the lower cover portion 36 as a reflective surface, it is possible to reflect the ultraviolet rays emitted from the ultraviolet irradiation portion 32 and collect the ultraviolet rays on the conveying surface 22 side. Note that the protective portion 34 and the lower cover portion 36 cannot rotate relative to the ultraviolet irradiation portion 32 .

FIG. 5 is a cross-sectional view showing a rod-shaped body 130 and rotating rollers 24, 25, and 26 around the rod-shaped body 130 according to a modification. The rod-shaped body 130 differs from the rod-shaped body 30 shown in FIG. 4 in that it has a rotating cover portion 138 . The rotating cover portion 138 shown in FIG. 5 has a hollow cylindrical shape through which the ultraviolet irradiation portion 32 is inserted, and rotates relative to the ultraviolet irradiation portion 32 . Rotating cover portion 138 is made of an ultraviolet-transmitting material, such as transparent glass or transparent resin, similar to protective portion 34 shown in FIG. In this manner, the rotating cover portion 138 rotates while sliding around the ultraviolet irradiation portion 32, so that the rod-like body 130 can function like a free roller.

In the conveying roller conveyor 20 shown in FIGS. 1 and 3, it is also possible to use a rod-shaped body 130 instead of the rod-shaped body 30. As shown in FIG.

Further, the length of the ultraviolet shielding portion 50 in the conveying direction (X direction) is substantially equal to the length of the conveying roller conveyor 20 in the conveying direction (X direction). As a result, the upper, lower, left, and right sides of the transport roller conveyor 20 are surrounded by the ultraviolet shielding portion 50, and leakage of ultraviolet rays is prevented. The ultraviolet shielding portion 50 is made of an ultraviolet-impermeable metal material, resin material, wood, or the like, and can be made of, for example, an aluminum plate or an opaque resin board.
