Description

Technical Field

[0001] The present invention relates to the technical field of logistics disinfection and sorting, and particularly to a roller, a channel-type conveying device and a control method. Background Art

[0002] In the logistics and express delivery industry, there are multiple links such as shipping, long-distance transportation, and delivery, which require manual transfer, sorting, and dispatching. In some environments, bacteria or germs are easily adhered to the surface of express items and spread to other places along with the express items. In order to prevent express delivery employees or recipients from coming into contact with bacteria or germs, the collected express items are usually sterilized and disinfected. The existing sterilization and disinfection methods usually use ultraviolet sterilization, for example, the Chinese utility model patent with the publication number CN217366616U discloses a light disinfection structure for material packages. The light disinfection structure for material packages installs a tunnel-type sterilization and disinfection box on the conveyor table. The tunnel-type sterilization and disinfection box has a passing cavity, and a light disinfection area is provided in the passing cavity. A number of ultraviolet lamps are arranged in the light disinfection area, and the ultraviolet lamps are installed on the wall of the light disinfection area of the tunnel-type sterilization and disinfection box.

[0003] However, the existing sterilization and disinfection method has low efficiency. The ultraviolet lamps are fixedly arranged on the top wall or side wall of the tunnel-type disinfection cavity. When the express item passes through the tunnel-type disinfection cavity, there is basically no irradiation light source on the bottom surface of the express item, and the irradiation blind area is large.

[0004] Therefore, there is an urgent need for a roller, a channel-type conveying device and a control method, which use the roller to carry and transport the express item, and a light source member is arranged on the circumferential part of the cylinder body, and the bottom surface of the express item is sterilized and disinfected by the disinfection light emitted by the light source member, so as to improve the sterilization and disinfection efficiency. Summary of the Invention

[0005] An object of the present invention is to provide a roller, a channel-type conveying device and a control method, which improve the sterilization and disinfection efficiency, ensure that the disinfection light emitted by the light source member can irradiate the bottom surface of the item, and reduce the irradiation blind area.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0013] As an alternative technical solution, the lamp is located on one side of the limiting platform. The side of the limiting platform facing the lamp is set as an inclined surface, and the inclined surface inclines radially outward.

[0014] As an alternative technical solution, a cover body is tightly sleeved on the outer circumference of the cylinder body. The light source component is located inside the cover body, and the cover body is made of a material transparent in the ultraviolet light region.

[0015] As an alternative technical solution, pattern lines are provided on the outer wall of the cover body or the outer surface of the cylinder body.

[0016] As an alternative technical solution, the switch control component includes a plurality of electrode plates. The plurality of electrode plates are spaced around the circumferential portion of the cylinder body. The electrode plates are arranged in one-to-one correspondence with the light source components, and the electrode plates are used to be electrically connected to the carbon brush at a preset position.

[0017] As an alternative technical solution, the switch control component includes a second sensor. The second sensor is fixed on the cylinder body, and the second sensor is used to detect or judge the position of the light source component.

[0018] In a second aspect, a channel-type conveying device is provided, which includes a transmission channel and the roller as described above. A plurality of the rollers are rotatably arranged at the bottom of the transmission channel.

[0020] Rotate the roller to convey the article towards the outlet of the box body;

[0021] Monitor the rotation state of the roller. If it is monitored that the light source component rotates to the first preset orientation range, the switch control component controls the light source component to be turned on; if it is monitored that the light source component rotates to the second preset orientation range, the switch control component controls the light source component to be turned off.

[0022] As an alternative technical solution, the control method further includes the following steps:

[0023] Detect the distance between the roller and the article.

[0048] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific embodiments.

[0049] Embodiment 1:

[0050] As Figures 1 to 5 described, this embodiment provides a roller 100, which includes a cylinder body 1, a light source member 2, and a switch control member 3; the light source member 2 is installed on the circumference of the cylinder body 1, and the light source member 2 includes a lamp 21 for emitting disinfection light, and the lamp 21 includes a UV lamp or a UV LED; at least one switch control member 3 is provided, and the switch control member 3 is electrically connected to the light source member 2, and the switch control member 3 is used to control the light source member 2 to turn on or off.

[0051] Specifically, when an article is conveyed above the cylinder body 1, the switch control member 3 controls the light source member 2 to turn on, and the disinfection light emitted by the light source member 2 can irradiate the bottom surface of the article to irradiate and disinfect the bottom surface of the article, reducing the irradiation blind area; the switch control member 3 is electrically connected to the light source member 2 to control the turning on and off of the light source member 2. When the light source member 2 faces the article, the light source member 2 is controlled to turn on to achieve irradiation disinfection. When the light source member 2 does not face the article, the light source member 2 is controlled to turn off, thereby saving energy consumption and extending the service life of the light source member 2.

[0052] Both the UV lamp and the UV LED are existing products and can emit ultraviolet light.

[0053] In some cases, the switch control member 3 can control the light source member 2 to turn on in advance, so that the light source member 2 irradiates the front end surface of the article, or the switch control member 3 can control the light source member 2 to turn off with a delay, so that the light source member 2 irradiates the rear end surface of the article, thereby reducing the irradiation blind area and increasing the sterilization and disinfection efficiency.

[0054] Optionally, a plurality of light source components 2 are circumferentially arranged around the outer periphery of the cylinder body 1 at intervals. The specific number of the light source components 2 can be set according to actual needs. The light source components 2 facing the article are electrically connected to the switch control component 3, and the light source components 2 not facing the article are open-circuited with the switch control component 3.

[0055] Optionally, an installation groove 11 is formed in the circumferential portion of the cylinder body 1, and the light source component 2 is embedded in the installation groove 11. The roller 100 is used to carry and transport the article. When the article is directly above the roller 100, the cylinder body 1 is in direct contact with the article. In order to prevent the lamp 21 in the light source component 2 from being crushed by the article, in this embodiment, the light source component 2 is embedded in the installation groove 11, and the cylinder body 1 protects the light source component 2.

[0056] Optionally, at least one side of the installation groove 11 is provided with a limiting platform 12. A clamping groove 13 is formed at an interval between the limiting platform 12 and the bottom of the installation groove 11. The light source component 2 further includes an installation plate 22. The installation plate 22 is inserted into the clamping groove 13, and the lamp 21 is fixedly installed on the installation plate 22. In actual use of the roller 100 in this embodiment, the roller 100 rotates around a horizontal line, and the light source component 2 rotates with the cylinder body 1. The limiting platform 12 can limit the light source component 2 in the installation groove 11 and prevent the light source component 2 from radially disengaging from the cylinder body 1. Especially when the light source component 2 rotates to the bottom of the cylinder body 1, the light source component 2 is affected by gravity and centrifugal force, and the force for the light source component 2 to radially disengage from the cylinder body 1 is the sum of gravity and centrifugal force. In some embodiments, a limiting platform 12 is provided on one side of the installation groove 11, and in other embodiments, limiting platforms 12 are provided on both sides of the installation groove 11. When assembling the roller 100, the installation plate 22 is axially inserted into the clamping groove 13.

[0057] Optionally, the lamp 21 is located on one side of the limiting platform 12. The side of the limiting platform 12 facing the lamp 21 is set as an inclined surface 121, and the inclined surface 121 is inclined outward along the radial direction. A part of the disinfection light emitted by the lamp 21 directly irradiates the article, and the other part irradiates the inclined surface 121 and then refracts to the article. Therefore, setting the side of the limiting platform 12 facing the lamp 21 as the inclined surface 121 can improve the disinfection efficiency.

[0058] Optionally, a cover 4 is tightly sleeved on the outer periphery of the cylinder body 1. The light source member 2 is located inside the cover 4, and the cover 4 is made of a material transparent in the ultraviolet light region. The cover 4 can increase the distance between the light source member 2 and the item to be irradiated, so that there is a better irradiation distance between the light source member 2 and the item to be irradiated, thereby expanding the irradiation area of the light cone generated by the light source member 2, avoiding the bottom blind area, and further reducing the number of UV LEDs used, thus reducing costs and power consumption. The cover 4 can further isolate and protect the light source member 2 and the cylinder body 1. When the item has an irregular shape, such as having spikes, it can prevent the spikes of the item from piercing the lamp 21 of the light source member 2, or when the humidity of the item is relatively high, it can prevent the water droplets on the item from leaking into the installation groove 11, avoiding causing a short circuit or contamination of the light source member 2. The cover 4 can be made of quartz material or acrylic plate.

[0059] Optionally, at least one surface of the inner wall or outer wall of the cover 4 and the outer surface of the cylinder body 1 is provided with a pattern texture to improve the transmission efficiency, prevent the item from slipping on the cover 4 or the cylinder body 1, and the pattern texture can roughen the light-emitting characteristics of the surface of the cover 4, thereby increasing light scattering and light-emitting efficiency.

[0060] Optionally, the inner wall of the cover 4 is provided with a convex portion that extends radially inward and matches the installation groove 11, and can abut against the UV lamp or UV LED, improving the transmission efficiency between the cover 4 and the cylinder body 1, and at the same time reducing the multi-interface light loss during the process of UV light entering the cover 4 from the UV lamp or UV LED.

[0061] As Figures 1 to 3 described, in some embodiments, the switch control member 3 includes a plurality of electrode plates 31. The plurality of electrode plates 31 are spaced apart and surround the circumference of the cylinder body 1. The electrode plates 31 are arranged in one-to-one correspondence with the light source members 2, and the electrode plates 31 are used to be electrically connected to the brush 300 at a preset position. The installation position of the brush 300 in the channel-type conveying device is a fixed position, and the electrode plates 31 rotate with the cylinder body 1. When the electrode plate 31 comes into contact with the brush 300 and is electrically conducted, the light source member 2 corresponding to the electrode plate 31 is turned on, and the light source member 2 emits disinfection light. The electrode plate 31 is a ring structure, and the contact duration between the electrode plate 31 and the brush 300 is determined by the arc length of the electrode plate 31. The arc length of the electrode plate 31 can be set according to actual needs. After the electrode plate 31 completely disengages from the brush 300, the light source member 2 corresponding to the electrode plate 31 is turned off. Electrode plates 31 are arranged around both ends of the cylinder body 1. The electrode plate 31 at one end of the cylinder body 1 serves as the current input end, and the electrode plate 31 at the other end of the cylinder body 1 serves as the current output end. Or, two sets of electrode plates 31 are arranged around one end of the cylinder body 1. One set of electrode plates 31 serves as the current input end, and the other set of electrode plates 31 serves as the current output end. Arranging the two sets of electrode plates 31 at the same end of the cylinder body 1 is beneficial to improving the installation convenience of the roller 100 and facilitating the circuit layout.

[0062] As Figure 4 shown, in some other parallel embodiments, the switch control member 3 includes a second sensor 32 fixed to the circumferential portion of the cylinder 1. The second sensor 32 is used to detect or determine the position or orientation of each light source member 2 on the roller 100. The second sensor 32 can be selected as a gyroscope or a gravity sensor. The second sensor 32 monitors the position or orientation of the light source member 2 relative to the central axis of the cylinder 1 or the article to determine whether one or more light source members 2 are turned on. Optionally, the switch control member 3 includes a circuit board electrically connected to the second sensor 32 and the light source member 2. The second sensor 32 can feedback the position information of each light source member 2 on each roller 100 to the circuit board or the control module. The circuit board or the control module analyzes and determines whether the light source member 2 meets the turning-on condition, and the circuit board can control the light source member 2 to turn on or off. The specific structure of the circuit board is not the object of improvement in this embodiment, and the circuit board or the control module in this embodiment is an existing product.

[0063] Embodiment 2:

[0064] As Figure 6 and Figure 7 shown, this embodiment provides a channel-type conveying device, which includes a transmission channel 200 and rollers 100 as in Embodiment 1. A plurality of rollers 100 are rotatably arranged at the bottom of the transmission channel 200.

[0065] In some embodiments, the channel-type conveying device includes a plurality of electric brushes 300, and the switch control member 3 includes a plurality of electrode plates 31. An electric brush 300 is arranged on one side of each roller 100 where the electrode plate 31 is provided. When the roller 100 conveys an article, the electric brush 300 selectively abuts against the electrode plate 31. The position where the electrode plate 31 abuts against the electric brush 300 is the trigger position, and the trigger position is above the central axis of the cylinder 1.

[0066] In some other embodiments, the switch control member 3 includes a plurality of second sensors 32 and a circuit board, and each roller 100 is matched with a second sensor 32.

[0067] The channel-type conveying device includes a box body 500 and a motor. Using the motor as the transmission power is an existing technology, and the specific transmission method is not described in detail in this embodiment. The motor drives the roller 100 to rotate around the horizontal line, so that the article enters the transmission channel 200 from the entrance of the box body 500. A plurality of rollers 100 are arranged in sequence at the bottom of the transmission channel 200. The roller 100 conveys the article to the exit of the box body 500. The bottom surface, the front end surface, and the rear end surface of the article can all be irradiated and disinfected by the light source member 2 of the roller 100. And it is an existing technology that ultraviolet lamps 21 are arranged on the side wall or the top wall of the transmission channel 200, which is not described in detail in this embodiment.

[0068] When an article passes through the in-line conveyor device of this embodiment, the roller 100 is located at the bottom of the article, ensuring that the disinfection light emitted by the light source member 2 can irradiate the bottom surface of the article and reducing the irradiation blind area.

[0069] Embodiment Three:

[0070] As Figure 8 shown, this embodiment provides a control method for controlling the in-line conveyor device as in Embodiment Two. The control method includes the following steps:

[0071] Rotate the roller 100 to convey the article towards the outlet of the box body 500;

[0072] Monitor the rotation state of the roller 100. If it is detected that the light source member 2 rotates to the first preset orientation range, the switch control member 3 controls the light source member 2 to turn on. If it is detected that the light source member 2 rotates to the second preset orientation range, the switch control member 3 controls the light source member 2 to turn off.

[0073] In some embodiments, the electrode plate 31 and the brush 300 are used in cooperation to monitor the rotation state of the roller 100. In other embodiments, the second sensor 32 and the circuit board are used in cooperation to monitor the rotation state of the roller 100. When the light source member 2 rotates to the first preset orientation range, the electrode plate 31 is electrically connected to the brush 300, and the light source member 2 is turned on. Alternatively, the second sensor 32 controls the light source member 2 to turn on. The first preset orientation range of the light source member 2 refers to the orientation range from when the light source member 2 starts to face the bottom surface of the article to when it partially or completely deviates from the bottom surface of the article. The second preset orientation range of the light source member 2 refers to the orientation range from when the light source member 2 partially or completely deviates from the bottom surface of the article to when it starts to face the bottom surface of the article. In another embodiment, the specific angle range can be set according to actual needs, or according to the height of the article monitored by the first sensor 400, and dynamically set by the control module according to preset parameters to achieve better irradiation of the front and back surfaces of the article.

[0074] Adopting the control method of this embodiment can ensure that the disinfection light emitted by the light source member 2 can irradiate the bottom surface of the article and reduce the irradiation blind area.

[0075] Optionally, the control method further includes the following steps:

[0076] Detect the distance between the roller 100 and the object. If the distance between the roller 100 and the object is less than a preset value, the roller 100 is determined to be a working roller 101, and the light source part 2 in the working roller 101 that rotates to a first preset orientation range is turned on, and the light source parts 2 in other orientations of the working roller 101 are turned off. If the distance between the roller 100 and the object is greater than a preset value, the roller 100 is determined to be a non-working roller 102, and all light source parts 2 in the non-working roller 102 are turned off.

[0077] The channel conveying device also includes a first sensor 400, which is used to detect the distance between the roller 100 and the object or the height of the object, and divide the roller 100 into a working roller 101 and a non-working roller 102. All non-working rollers 102 cannot emit disinfection light, thereby reducing energy consumption; the light source 2 in the working roller 101 that rotates to the first preset direction range is turned on, and the light source 2 in the working roller 101 that rotates to the second preset direction range is turned off. The control method of this embodiment can ensure that the disinfection light emitted by the light source 2 can irradiate the bottom surface of the object or the front and rear surfaces along the forward direction of the object, reducing the irradiation blind area; at the same time, it ensures that the light source 2 is in a closed state when it is facing the ground or away from the object, etc., which does not need to be illuminated, saving energy consumption and extending the use and replacement cycle of the light source by at least one time, greatly meeting the disinfection requirements and achieving carbon reduction goals.

[0078] like Figure 7 As shown, if the horizontal distance between the roller 100 and the object is less than L, the roller 100 is judged as a working roller 101, and if the horizontal distance between the roller 100 and the object is greater than L, the roller 100 is judged as a non-working roller 102. It can be understood that the horizontal distance between the roller 100 directly below the object and the object is also less than L, and the roller 100 can effectively disinfect the side and bottom surfaces of the object.

[0079] In addition, the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
