[0002] In recent years, with the rapid development of the express logistics industry, the number of express parcels has increased sharply year by year, among which the number of small parcels has increased significantly. Due to the large number, small size and light weight of small parcels, the use of traditional belt conveyors has the problem of large equipment docking gap and easy clamping. Utility Model Content

[0003] The technical problem to be solved by the embodiments of the utility model is to provide a single-piece flow high-speed conveying fine roller belt machine, which solves the problems of low efficiency, clamping and belt deviation of existing single-piece flow packages.

[0004] To achieve the above-mentioned purpose, the utility model discloses a single-piece flow high-speed conveying fine roller belt conveyor, comprising a machine body, a conveying mechanism, a pallet assembly, a tensioning mechanism, a photoelectric detection module, and a PCL unit. The conveying mechanism is rotatably arranged on the machine body, the pallet assembly is arranged on the machine body, and the height of the pallet assembly is higher than the top of the machine body. The tensioning mechanism is arranged inside the machine body and is used to adjust the tightness of the conveying mechanism. The photoelectric detection module is arranged on the head end of the machine body, and the PCL unit is electrically connected to the photoelectric detection module. After the photoelectric detection module detects that a package enters the conveying mechanism, it feeds back to the PCL unit, so that the PCL unit adjusts the conveying speed of the conveying mechanism according to the position between the packages. By adopting the photoelectric detection method, the single-piece conveying efficiency and the package sorting efficiency are improved;

[0005] Among them, the conveying mechanism includes a belt, a redirecting roller, a tensioning roller, and a driving roller. The redirecting roller is a pair and is rotatably arranged at the head and tail ends of the fuselage respectively. The driving roller is rotatably arranged in the fuselage. The tensioning roller is slidably arranged between the redirecting roller and the driving roller. The belt is tensioned on the redirecting roller, the tensioning roller, and the driving roller. The driving roller is driven by a rotating driving device to drive the belt to rotate, thereby realizing automatic transportation of the package. The tensioning roller adjusts the tensioning force of the belt under the drive of the tensioning mechanism to ensure the stability of the belt during the transmission process.

[0006] Furthermore, the belt includes a first splicing surface and a second splicing surface that are spliced ​​with each other, and the first splicing surface and the second splicing surface of the belt are arranged in an inclined plane. By adopting oblique splicing, the belt can reduce the contact area between the splicing and the roller, which can reduce the force on the roller compared to a right-angle transition, and at the same time reduce the noise of the equipment.

[0007] Furthermore, the redirecting roller includes a fixed shaft and a round tube, the round tube is sleeved on the fixed shaft, and the end of the fixed shaft is rotatably connected to the round tube through a bearing, the middle part of the round tube is cylindrical, and the end of the round tube is cone-shaped, thereby preventing the belt from deviating.

[0008] Furthermore, the inclination angles of the two ends of the circular tube are respectively 0.2°-1°.

[0009] Furthermore, the tensioning mechanism includes a tensioning seat, an adjusting rod, a movable seat, and a positioning seat. The tensioning seat is fixedly arranged on the inner wall of the fuselage, and the positioning seat is a pair and fixedly arranged on the front and rear inner walls of the tensioning seat. The adjusting rod is rotatably arranged between the positioning seats, and the end of the adjusting rod extends outward and is fixedly connected to the tensioning seat through a nut. The movable seat is slidably arranged on the tensioning seat and is threadedly connected to the adjusting rod, and the end of the tensioning roller is rotatably connected to the movable seat. The nut is loosened to rotate the adjusting rod to drive the movable seat to slide along the tensioning seat, so as to adjust the tightness of the belt and make the transmission of the belt more reliable.

[0010] Furthermore, the pallet assembly includes a pallet and a plurality of rollers. The pallet is fixedly arranged on the upper part of the fuselage. Support seats are fixedly arranged at the head and tail ends of the pallet. The support seat is provided with a plurality of roller seats along the width direction. The plurality of rollers are rotatably arranged on the roller seats respectively. The belt is tensioned on the rollers, and the pallet supports the upper surface of the belt, so that the transmission of the belt is more stable and the belt is prevented from sinking due to heavy packages.

[0011] Furthermore, the fuselage includes a first side panel, a second side panel, and a front side panel and a rear side panel respectively arranged at the front and rear ends of the first side panel and the second side panel, the two sides of the support plate are respectively fixedly connected to the first side panel and the second side panel, baffles are respectively fixedly arranged on the top of the first side panel and the second side panel, and supporting legs are arranged between the lower parts of the two ends of the first side panel and the second side panel.

[0012] Furthermore, the PCL unit is electrically connected to the rotary drive device so that when the package passes through the photoelectric detection module, the visual detection module obtains the size and position of the package, so that the PCL unit can quickly and dynamically adjust the package speed and spacing. At the same time, the visual detection module can make up for the shortcomings of the photoelectric detection module and realize package position tracking.

[0013] Furthermore, it also includes a visual inspection module, which is arranged above the conveying mechanism and electrically connected to the PCL unit. The visual inspection module is used to obtain image information on the conveying mechanism and feed the image information back to the PCL unit, so that the PCL unit adjusts the conveying speed of the conveying mechanism according to the image information. In this way, by adopting the visual inspection method, the shortcomings of radio and television inspection can be compensated, sorting errors can be avoided, and the single-piece conveying efficiency and package sorting efficiency can be improved.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) In this embodiment, the rollers and baffles are lower than the belt surface, so that the belt conveyors are arranged side by side, reducing the clamping of single-piece flow packages and improving the efficiency of package sorting. (2) The integrated support plate design is adopted to improve the parallelism of the rollers at the head and tail ends. (3) In this embodiment, the end of the redirection roller is cone-shaped, and the belt adopts an oblique splicing design to prevent the belt from running off track. (4) In addition, this embodiment uses photoelectric + visual control to quickly and dynamically adjust the package speed and spacing.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 , 3 , Figure 7As shown, a single-piece flow high-speed conveying fine roller belt machine includes a fuselage 1, a conveying mechanism 2, a pallet assembly 3, a tensioning mechanism 4, a photoelectric detection module 5, and a visual detection module 6. The conveying mechanism 2 is rotatably arranged on the fuselage 1, the pallet assembly 3 is arranged on the fuselage 1, and the height of the pallet assembly 3 is higher than the top of the fuselage, the tensioning mechanism 4 is arranged inside the fuselage 1, the photoelectric detection module 5 is arranged on the head and tail ends of the fuselage 1, and the visual detection module 6 is arranged above the conveying mechanism 2.

[0025] The fuselage 1 includes a first side panel 11, a second side panel 12, and a front side panel and a rear side panel respectively arranged at the front and rear ends of the first side panel 11 and the second side panel 12, and a support leg 14 is arranged between the lower parts of the two ends of the first side panel 11 and the second side panel 12. In this embodiment, the conveying mechanism 2, the pallet assembly 3, and the tensioning mechanism 4 are respectively arranged between the first side panel 11 and the second side panel 12.

[0026] Among them, the transmission mechanism 2 includes a belt 21, a redirecting roller 22, a tensioning roller 23, and a driving roller 24. The redirecting rollers 22 are a pair and are rotatably arranged at the head and tail ends of the fuselage 1 respectively. The driving roller 24 is rotatably arranged in the fuselage 1, and the tensioning roller 23 is slidably arranged between the redirecting roller 22 and the driving roller 24. In this embodiment, the belt is made of PVC material. The belt 21 is tensioned on the redirecting roller 22, the tensioning roller 23, and the driving roller 24. A rotating driving device 25 is fixedly installed on one side of the fuselage 1. In this embodiment, the rotating driving device 25 preferably adopts a reduction motor, and its output shaft is fixedly connected to the driving roller 24. The driving roller 24 is driven by the rotating driving device 25 to drive the belt 21 to rotate.

[0027] More preferably, the belt 21 in this embodiment includes a first splicing surface and a second splicing surface that are spliced ​​together. The first splicing surface and the second splicing surface of the belt 21 are arranged at an inclined surface, so that the splicing between the belts adopts an oblique splicing design, thereby reducing the contact area between the splicing and the roller. Compared with the traditional right-angle transition, it can reduce the force on the roller and reduce the noise of the equipment.

[0028] In addition, in this embodiment, the redirecting roller 22 includes a fixed shaft 221 and a circular tube 222. The circular tube 222 is sleeved on the fixed shaft 221, and the end of the fixed shaft 221 is rotatably connected to the circular tube 222 through a bearing 223, so that the circular tube can roll along with the belt. In this embodiment, the middle part of the circular tube 222 is cylindrical, and the end of the circular tube 222 is cone-shaped. The inclination angles of the ends of the circular tube 222 are 0.2°-1°, respectively, to prevent the belt from running off track.

[0029] In order to make the transmission of the belt more stable, the present embodiment uses a pallet assembly to hold the upper surface of the transmission mechanism. Specifically, the pallet assembly 3 includes a pallet 31 and a plurality of rollers 32. The pallet 31 is fixedly arranged on the upper part of the fuselage 1, that is, the two sides of the pallet 31 are respectively fixedly connected to the first side plate 11 and the second side plate 12. The front and rear ends of the pallet 31 are fixedly provided with a support seat 33. The support seat 33 is provided with a plurality of roller seats 34 along the width direction. The plurality of rollers 32 are respectively rotatably arranged on the roller seats 34. The belt 21 is tensioned on the rollers 32 so that the pallet 31 holds the upper surface of the belt 21, thereby preventing the belt from sinking due to the heavy package, and making the transmission of the package more stable.

[0030] Baffles 13 are fixedly provided on the top of the first side plate 11 and the second side plate 12 respectively to prevent the packages from slipping out of the two sides of the belt during the conveying process, thereby affecting the sorting of the packages.

[0031] And because the height of the pallet in this embodiment is higher than the height of the top surface of the fuselage, the belt or package is prevented from getting stuck in the gap between the first side panel / second side panel and the baffle, ensuring the normal transportation of the package and facilitating the installation and maintenance of the pallet.

[0032] The tensioning mechanism 4 includes a tensioning seat 41, an adjusting rod 42, a moving seat 43, and a positioning seat 44. The tensioning seat 41 is fixedly arranged on the inner wall of the fuselage 1. The positioning seat 44 is a pair and is fixedly arranged on the front and rear inner walls of the tensioning seat 41. In this embodiment, the positioning seat 44 is fixed to the tensioning seat 41 by a fixing bolt 46. The middle of the positioning seat 44 has a through hole. The ends of the adjusting rod 42 are respectively inserted into the positioning seat 44, and the ends of the adjusting rod 42 extend outward and are fixedly connected to the tensioning seat 41 through a nut 45. The moving seat 43 is slidably arranged on the tensioning seat 41 and is threadedly connected to the adjusting rod 42. In this embodiment, the end of the tensioning roller 23 is rotatably connected to the moving seat.

[0033] When the belt 21 becomes loose, the nut 45 on the adjusting rod 42 is loosened and then the adjusting rod 42 is rotated to drive the movable seat 43 to slide along the tensioning seat 41, so as to adjust the tension of the belt through the tensioning roller. When the tension of the belt 21 is adjusted appropriately, the nut 45 on the adjusting rod 42 needs to be tightened to fix the adjusting rod 42 and prevent the tensioning roller 23 from moving.

[0034] The front end of the baffle 13 is fixedly connected to a connecting plate 131, and a photoelectric hole 132 is opened on the connecting plate 131. The photoelectric detection module 5 is fixedly arranged at the photoelectric hole 132 of the connecting plate 131. In this embodiment, the photoelectric detection module 5 preferably adopts a photoelectric sensor, and the photoelectric hole 132 on the connecting plate 131 in this embodiment is consistent with the height of the belt 21, thereby ensuring that the photoelectric detection module 5 can detect ultra-thin small items on the belt 21, thereby greatly improving the detection accuracy of the belt conveyor.

[0035] A frame 7 is provided above the fuselage 1, and a visual inspection module 6 is fixedly mounted on the frame 7. In this embodiment, the visual inspection module 6 preferably adopts an industrial camera, and the size and position of the package on the belt 21 are obtained through the visual inspection module 6, and the visual inspection module 6 can make up for the insufficient detection of the photoelectric inspection module 5. Due to the presence of ultra-thin small items, the photoelectric inspection module 5 cannot be directly set in the middle of the fuselage 1, but can only be designed at the joint of the two belt machines to improve the detection accuracy of the photoelectric inspection module 5. At the same time, the visual inspection module 6 is used to track the position of the package, which effectively improves the detection stability of the equipment and avoids incorrect sorting.

[0036] The present embodiment also includes a PCL unit, which is electrically connected to the photoelectric detection module 5, the visual detection module 6, and the rotation drive device 25, respectively. When the photoelectric detection module 5 detects that a package enters the conveying mechanism 2, the visual detection module 6 then obtains the image information of the package on the conveying mechanism 2, identifies the size and position information of the package based on the image information, and feeds back the information to the PCL unit, so that the PCL unit adjusts the conveying speed of the belt 21 based on the size and position information of the package, thereby quickly and dynamically adjusting the speed and spacing of the packages.

[0037] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical scheme of the utility model should be included in the protection scope of the utility model.
