Description

Technical Field

[0001] This invention relates to the field of irradiation sterilization technology, and more particularly to an irradiation sterilization device. Background Technology

[0002] Irradiation sterilization is an effective method that uses electromagnetic waves generated by ionizing radiation to kill microorganisms on most materials. X-rays and gamma rays can oxidize other substances or generate free radicals that then act on biomolecules, or act directly on biomolecules, breaking hydrogen bonds, oxidizing double bonds, destroying ring structures, or polymerizing certain molecules, thereby damaging and altering the structure of biological macromolecules, thus inhibiting or killing microorganisms. After goods are conveyed to the electron beam for irradiation, according to process requirements, the dose of electron irradiation rays cannot penetrate large-volume goods. Therefore, this type of goods needs to be irradiated once, then flipped, and then irradiated again under the electron beam. Patent CN 115593885 B discloses an electron beam irradiation flipping device, including a conveying mechanism, a positioning mechanism, a flipping mechanism, and a shaping mechanism. The flipping method of this solution uses a robotic arm (flipping mechanism) to flip the goods. However, the cost of using a robotic arm in conjunction with a conveyor line is relatively high. The robotic arm also requires space in addition to the conveyor line, and the robotic arm is always located below the irradiation device during the flipping process, which occupies the irradiation range. This forces the conveyor line to stop transporting subsequent goods to wait for the flipping, which reduces the irradiation efficiency. Therefore, how to design an irradiation flipping sterilization mechanism that is highly compatible with the conveyor line and can continuously transport large-volume goods and irradiate the goods before and after flipping has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings mentioned above by providing an irradiation sterilization device that occupies a small area and can continuously irradiate and transport goods.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an irradiation sterilization device, comprising,

[0005] A conveyor rail A is raised in a ring shape, and a conveyor rail B is connected to the output end of the conveyor rail A. Goods enter the conveyor rail A at intervals.

[0006] Two retractable support devices are provided at the output end of the conveyor rail A. The gap between the two support devices is smaller than the width of the conveyed goods. Each support device includes a wedge-shaped support block. Goods input at the inlet of the conveyor rail A can compress the inclined surface of the support block to shrink it, allowing the goods to move normally on the conveyor rail A. Multiple rollers are provided on the top of the support block. Goods that move to the output end of the conveyor rail A fall on the top of the support block and enter the conveyor rail B under the drive of each roller. The conveyor rail B is located on top of the conveyor rail A. Goods on the conveyor rail A pass under the conveyor rail B when they pass the intersection of the conveyor rail A and the conveyor rail B.

[0007] An irradiation device is mounted above the two aforementioned support devices;

[0008] A flipping mechanism, installed on the conveyor rail A, is used to flip the goods after one irradiation.

[0009] Furthermore, the bearing device also includes two supports respectively disposed on the outer wall of the conveyor rail A and a gas spring installed on the supports. The bearing block is disposed on the gas spring. A constriction inlet larger than the bearing block is opened at the side wall of the conveyor rail A. The two bearing blocks are squeezed into the inner side of the constriction inlet by the cargo.

[0010] Furthermore, multiple conveying rollers A and B are respectively arranged at intervals on the inner sides of the conveying rail A and the conveying rail B, and the conveying roller B gradually rises from the input end to the output end.

[0011] Furthermore, the flipping mechanism includes a flipping rod disposed at the gap between the two conveying rollers A and a linear module that drives the flipping rod to rise and fall. The linear module is vertically disposed at the side wall of the conveying rail A, and the linear module drives the flipping rod to push the goods upward from the gap between the conveying rollers A to flip the goods.

[0012] Furthermore, the conveyor rollers A on both sides of the flipping mechanism are covered with an anti-slip and anti-collision layer.

[0013] Furthermore, a light sensor is provided at the top of the flipping rod, which is used to sense whether goods are passing above the flipping rod.

[0014] Furthermore, an anti-scratch layer is provided on the inclined surface of the bearing block.

[0015] The beneficial effects of this invention are reflected in:

[0016] This invention establishes a conveyor line that passes through an irradiation device twice, using conveyor rails A and B. Conveyor roller B, above conveyor roller A, is divided into two sections. When goods are conveyed on conveyor rail A and pass through the irradiation device, they undergo one irradiation. As conveying continues, the goods are transported above a turning mechanism, which pushes the goods upwards. The other end of the goods remains on conveyor roller A, causing the goods to gradually turn as they are conveyed by conveyor roller A. The direction of the turning is opposite to the conveying direction of conveyor roller A. As conveying continues, the goods continue to turn until they have turned 180 degrees. After turning, the turning mechanism is driven to rise further over the goods, thus releasing the goods from their limiting state and allowing them to continue being conveyed. The goods are transported to a support block, where rollers transport them to conveyor roller B. The goods above the support block undergo a second irradiation through the irradiation device. This allows for the continuous transport, turning, and irradiation of goods. This device is fully compatible with conveyor lines, does not occupy extra space beyond the conveyor line, and has low cost, making it easy to promote and use. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-4This invention discloses an irradiation sterilization device, comprising a gradually rising annular conveyor rail A1 and a conveyor rail B3 connected to the output end of conveyor rail A1. Goods enter conveyor rail A1 at intervals and are transported to the output end along the annular trajectory of conveyor rail A1. Two support devices 8 are retractably installed at the output end of conveyor rail A1, with the gap between the two support devices 8 being smaller than the width of the conveyed goods. The support device 8 includes a wedge-shaped support block 83. Goods input at the inlet of conveyor rail A1 can compress the inclined surface of the support block 83 to shrink it, allowing the goods to move normally on conveyor rail A1. Multiple rollers 84 are rotatably installed on the top of the support block 83. Goods that move to the output end of conveyor rail A1 fall on the top of the support block 83 and enter conveyor rail B3 under the drive of each roller 84. An irradiation device 7 is mounted above the two support devices 8, and a flipping mechanism 9 is provided on conveyor rail A1. The flipping mechanism 9 is used to flip the goods after one irradiation.

[0025] In practice, the goods to be irradiated are input from the entrance of conveyor rail A1. They pass between two support blocks 83 and are squeezed and compressed. The reaction force pushes the goods to the conveying center of conveyor rail A1. The goods then pass through the irradiation area of ​​irradiation device 7 for a first irradiation. As the conveying continues, the goods move along the circular direction of conveyor rail A1 and are conveyed upwards. When the head of the goods passes the flipping mechanism 9, the flipping mechanism 9 flips the goods in the opposite direction to the conveying direction of conveyor rail A1. After the flipping is completed, the goods continue to be conveyed to the support block 83 and then irradiated a second time by irradiation device 7. After the second irradiation is completed, the goods are transported forward into conveyor rail B3 with the assistance of multiple rollers 84. The goods are finally output as they follow the conveying trajectory of conveyor rail B3. This device can transport, flip, and irradiate goods while continuously conveying them. This device is fully compatible with conveyor lines and does not occupy extra space other than the conveyor line. Furthermore, this device has a low cost, making it easy to promote and use.

[0026] It should be noted that the multiple rollers 84 can be connected to a motor to rotate and actively drive the goods on them to move, or they can be unpowered. When the multiple rollers 84 are not externally connected and have no power, when the goods on the conveyor rail A1 pass the bearing block 83, the top of the goods can push the goods on the bearing block 83 forward until one end of the goods on the bearing block 83 contacts the conveyor rail B3 and is driven forward by the conveyor rail B3.

[0027] In one embodiment, the carrying device 8 further includes two supports 81 respectively installed on the outer wall of the conveying rail A1 and a gas spring 82 installed on the supports 81. The carrying block 83 is installed on the movable end of the gas spring 82. A constriction inlet 10 with a size larger than the carrying block 83 is opened on the side wall of the conveying rail A1. The two carrying blocks 83 are squeezed into the inside of the constriction inlet 10 by the extrusion of the goods.

[0028] In practice, when the two support blocks 83 are squeezed by the cargo, the gas spring 82 contracts, causing the support blocks 83 to retract into the inner side of the retraction inlet 10. Furthermore, the elastic force of the gas spring 82 is adapted to the weight of the cargo, so that when the cargo of a certain weight is squeezed, it can be squeezed into the retraction inlet 10, and the cargo can be squeezed by the two support blocks 83 to the middle conveying point of the conveying rail A1.

[0029] In one embodiment, multiple spaced conveyor rollers A2 and B4 are rotatably mounted on the inner sides of conveyor rails A1 and B3, respectively. The conveyor rollers B4 gradually rise from the input end to the output end. An assembly frame 11 is mounted on the inner side of conveyor rail B3. The assembly frame 11 is rotatably connected to the multiple conveyor rollers B4, so that the multiple conveyor rollers B4 maintain stability when rotating.

[0030] In specific implementation, sprocket boxes 5 are installed on the outer walls of both conveyor rails A1 and B3. A servo motor 6, serving as a power source, is installed on the outer side of the sprocket box 5. The sprocket box 5 includes multiple sprockets rotatably mounted in the box body. Two sprockets form a group, with one sprocket in each group overlapping each other. A chain is connected to the outer side of each group of sprockets. Each sprocket is simultaneously connected to each conveyor roller A2 and conveyor roller B4 in both conveyor rails A1 and B3. Therefore, when the servo motor 6 drives one of the sprockets in the sprocket box 5 to rotate, the other sprockets can be driven simultaneously through the chain. The above-mentioned sprocket installation method, combined with the ring-shaped distributed rollers, enables ring-shaped conveying. The above-mentioned roller driving method is a well-known technology in the field of conveyor lines, so it will not be described in detail here.

[0031] In one embodiment, the flipping mechanism 9 includes a flipping rod 92 disposed at the gap between the two conveying rollers A2 and a linear module 91 that drives the flipping rod 92 to rise and fall. The linear module 91 is vertically mounted on the side wall of the conveying rail A1. The linear module 91 drives the flipping rod 92 to push the goods upward from the gap between the conveying rollers A2 and flip them.

[0032] In practice, the linear module 91 drives the flipping rod 92 to rise from below the two conveyor rollers A2 on its left and right sides. The flipping rod 92 passes through the gap between the two conveyor rollers A2 and rises above them. Initially, the flipping rod 92 is located below the two conveyor rollers A2. When the goods move above the flipping rod 92, the linear module 91 drives the flipping rod 92 to rise and push the goods, causing them to tilt. As the conveyor rollers A2 continue to transport the goods, the other end of the goods is carried forward by the conveyor rollers A2, causing the goods to rotate in the opposite direction of the conveyor rollers A2 until the end of the goods that is in contact with the conveyor rollers A2 is in front and the end that is resting on the flipping rod 92 is behind. The rear end of the goods will fall directly onto the conveyor rollers A2, thus completing the flipping. After the goods have flipped and moved forward, the linear module 91 drives the flipping rod 92 to fall below the two conveyor rollers A2, so that subsequent goods can be flipped repeatedly. This method is efficient, reliable, and easy to use in practice.

[0033] In one embodiment, the conveying rollers A2 on both sides of the flipping mechanism 9 are covered with an anti-slip and anti-collision layer.

[0034] In practice, the anti-slip and anti-collision layer can be a silicone layer. When the goods are flipped on the conveyor roller A2 near the flipping mechanism 9, the silicone layer can prevent the goods from slipping and affecting the efficiency of the transport flipping. Furthermore, when the goods are flipped by the flipping mechanism 9, the silicone layer can prevent the goods from directly colliding with the conveyor roller A2, thus effectively protecting the safety of the goods and the conveyor roller A2.

[0035] In one embodiment, a light sensor is mounted on the top of the flip bar 92, and a controller electrically connected to it is mounted on the linear module 91. The light sensor is signal-connected to the controller. The light sensor is used to sense whether goods are passing above the flip bar 92.

[0036] In practice, when the goods pass over the flipping rod 92, the light sensor detects that the light has dimmed and sends a signal to the controller. The controller then controls the linear module 91 to start, thereby driving the flipping rod 92 to move upward and flip the goods.

[0037] In one embodiment, a scratch-resistant layer is installed on the inclined surface of the support block 83. The scratch-resistant layer can be a soft silicone rubber layer with a smooth surface. When the goods squeeze the two support blocks 83 and move forward, the scratch-resistant layer can prevent the goods from being scratched.

[0038] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0039] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0040] Additionally, "multiple" refers to two or more.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
