[0001] The utility model relates to the technical field of jewelry sorting, and more specifically to a three-axis double-feeding sorting device for round jewelry. Background Art

[0002] In the production process of round jewelry, the sorting of jewelry raw materials is crucial. Jewelry sorting equipment can classify gems according to color, size, glossiness and other characteristics. There are various types of existing jewelry sorting equipment, such as the dual-camera crawler sorting machine. The sorting method has problems such as low accuracy. The main reason is that there is a visual blind spot when taking static photos of the round sphere, which makes it impossible to identify the defects in the visual blind spot. Therefore, a new type of sorting device is needed to improve the sorting accuracy.

[0003] Another example is a blanking device for a jewelry color sorter disclosed in publication number CN 210995387 U, which uses a single screw structure, and the sorting accuracy is improved, but the single-side blanking efficiency is relatively low, and the transmission is only through the screw, and there is still a problem that the jewelry cannot be fully detected. At the same time, due to the complex mechanical structure, the existing technology does not add an abnormal detection sensor, which is easy to cause permanent damage to the machine when the material is blocked. Utility Model Content

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the sake of illustration and convenience of description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0026] like Figure 1-6 As shown, the technical solution of the utility model provides a three-axis double-feeding and sorting device for round jewelry, which is used to sort round jewelry materials according to parameters such as color and shape. The device includes a storage hopper 1, two sets of feeding mechanisms 2 arranged on both sides of the storage hopper 1, a conveying mechanism 4 located below the feeding mechanism, an optical detection mechanism 7 located above the conveying mechanism 4, and a sorting mechanism 8 located at a station behind the optical detection mechanism 7. Jewelry raw materials are placed in the storage hopper 1, and the feeding mechanism 2 conveys the raw materials one by one to the conveying mechanism 4, and then the conveying mechanism 4 conveys the raw materials forward, and after being detected by the optical detection mechanism 7, they arrive at the sorting place, and then the sorting mechanism 8 classifies and puts the raw materials according to the detection results.

[0027] The material discharging mechanism 2 includes a material discharging hopper 21 connected to the storage hopper 1, a stirring mechanism located on the material discharging hopper 21, a discharging pipe 25 connected to the material discharging hopper 21, and a material distributing mechanism located below the material discharging pipe 25 for allowing the materials to sequentially enter the conveying mechanism 4. The raw materials will enter the material discharging hopper 21 through the storage hopper 1, and the stirring mechanism provided in the material discharging hopper 21 will continuously stir in the material discharging hopper 21 to prevent the raw materials from accumulating in the material discharging hopper 21. After the raw materials enter the material discharging hopper 21, they will enter the material distributing mechanism through the discharging pipe 25. The material distributing mechanism will receive the raw materials and allow the raw materials to sequentially enter the conveying mechanism 4.

[0028] The stirring mechanism includes a stirring motor 22, a stirring rod 23 connected to the output end of the stirring motor 22, and a stirring plate 24 fixed to the end of the stirring rod 23, wherein the stirring plate 24 is located in the lower hopper 21 and close to the outlet of the lower hopper 21. The stirring motor 22 drives the stirring plate 24 on the stirring rod 23 to rotate, thereby stirring the raw materials for better feeding.

[0029] The material distribution mechanism includes a material distribution motor 26, a material distribution plate 27 connected to the output end of the material distribution motor 26, and a limit block 29 located on one side of the material distribution plate 27. The limit block 29 has an arc surface, and the arc surface is close to the outer surface of the material distribution plate 27. The outer circumference of the material distribution plate 27 is equidistantly provided with a plurality of storage holes 28. The raw materials fall into the storage holes 28 on the material distribution plate 27 through the discharge pipe 25. Each storage hole 28 stores a raw material. The material distribution motor 26 drives the material distribution plate 27 to rotate, and at the same time limits the position of the limit block 29 on one side to prevent the raw materials from falling from the side of the material distribution plate 27 during the rotation process. When the material distribution plate 27 rotates to be opposite to the conveying mechanism 4, the raw materials enter the conveying mechanism 4 from the storage holes 28. The setting of the material distribution plate 27 can ensure that the raw materials enter the conveying mechanism 4 in sequence, and avoid the stacking of raw materials and the influence of detection.

[0030] The discharge end of the discharge mechanism 2 is provided with a blockage detection module, and the blockage detection assembly includes a blockage detection sensor 3 located outside the discharge pipe 25. The blockage detection sensor 3 is used to detect whether the discharge pipe 25 is normally discharged to ensure normal feeding.

[0031] The conveying mechanism 4 includes a main screw 41 and two rotating rods 42 located on both sides of the main screw 41. Two feeding channels 44 are formed between the two rotating rods 42 and the main screw 41. The main screw 41 and the rotating rods 42 rotate simultaneously, and the two unloading mechanisms 2 correspond to the two feeding channels 44 respectively. The main screw 41 is driven by a driving motor 43. By setting two rotating rods 42 and one main screw 41, two feeding channels 44 can be formed, and the two feeding channels 44 feed materials at the same time, thereby improving the sorting efficiency. The end of the rotating rod 42 is connected to the main screw 41 through a transmission belt 45, and can rotate synchronously with the main screw 41, thereby ensuring that the raw material is in a rotating state when passing through the optical detection mechanism 7, thereby improving the detection accuracy. At the same time, a driving device can also be set separately to drive the rotating rod 42, so as to achieve flexible adjustment of the speed for the screening of jewelry with different glossiness.

[0032] A detection piece 5 is provided at one end of the main screw 41, and a main screw rotation detection sensor 6 corresponding to the position of the detection piece 5 is provided on one side of the main screw 41. The detection piece 5 rotates with the main screw 41, and the main screw rotation detection sensor 6 is used to detect the condition of the main screw 41. When it is detected that the main screw 41 is running abnormally or blocked, an alarm message is sent in time to avoid permanent damage to the machine and improve the safety of use.

[0033] The optical detection mechanism 7 includes a mounting bracket 71, a light source 72 and a visual camera 73 arranged on the mounting bracket 71. The visual camera 73 is a CCD camera, which takes pictures of the rolling jewelry for identification, and after identification and classification, it is transported to the sorting mechanism 8, and the channels of the corresponding types on the sorting mechanism 8 are opened to guide the raw materials into the corresponding channels.

[0034] The sorting mechanism 8 includes a plurality of solenoid valves 81, a sorting block 82 connected to the solenoid valves 81, and a return spring 83 between the solenoid valves 81 and the sorting block 82. A material guide tube 84 corresponding to the sorting block 82 is arranged below the sorting block 82. Each solenoid valve 81 corresponds to a type of raw material. When the discrimination is completed, the corresponding solenoid valve 81 drives the sorting block 82 on it to contract, and the raw material is transported to the corresponding position and enters the material guide tube 84 below from the material drop channel formed by the sorting block 82 and the main screw 41, and then is collected by the collecting device.

[0035] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
