[0055] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings:

[0056] See also Figures 1 to 9 The jewelry color sorter of the present invention comprises a frame 1, a feeding device 2, a color sorting device 3 and a sorting device 4. Among them:

[0057] The frame 1 comprises a support frame 11 and a frame platform 12 arranged on the support frame. The feeding device 2, the color sorting device 3 and the sorting device 4 are all fixed on the frame platform 12 in sequence.

[0058] The feeding device 2 comprises a feeding bin 21 and a pushing mechanism 22 .

[0059] The loading bin 21 is fixed on the frame and is used to contain jewelry. The loading bin 21 includes a feeding bin 211 , a pushing bin 212 and a supporting platform 213 .

[0060] The feed bin 211 is fixedly connected to the frame. In this specific embodiment, the feed bin is supported on the frame platform by four support columns. A discharge port is provided below the feed bin 211. The jewelry in the feed bin enters the push bin through the discharge port.

[0061] The push bin 212 is arranged below the feed bin 211 and is fixedly connected to the frame. The push bin includes a front baffle 2121 at the front end, a rear baffle 2122 at the rear end, a left baffle 2123 at the left side, a right baffle 2124 at the right side, and a lower baffle 2125 at the bottom.

[0062] The front baffle plate 2121 is provided with a material pushing port 21211 located above the support platform, and the jewelry pushed out from the material pushing port enters the color sorting device.

[0063] The lower baffle plate 2125 is arranged below the material discharge port and is inclined toward the front and downward. The lower baffle plate is inclined to facilitate the jewelry to roll down from the material discharge port along the lower baffle plate to the material pushing mechanism.

[0064] In order to adjust the amount of jewelry entering the push bin from the feed bin, an adjustment plate 2111 is provided on the front end surface of the feed bin 211, which can be adjusted up and down along the front end surface of the feed bin to adjust the distance between the front end of the discharge port and the lower baffle. The adjustment of the adjustment plate 2111 can be achieved directly by slotting the adjustment plate or the front side wall of the feed bin and fixing it with screws.

[0065] The support platform 213 is arranged on the front side wall of the loading bin. In this specific embodiment, the support platform is fixed on the front baffle plate 2121 of the pushing bin.

[0066] The upper end of the support platform 213 is provided with a downward-sloping and downwardly concave sliding groove 2131 that slopes forward. The purpose of setting the sliding groove is to facilitate the jewelry to slide down from the upper end of the sliding groove to the lower end of the sliding groove. In this specific embodiment, the sliding groove is composed of two intersecting inclined planes.

[0067] The pushing mechanism 22 is connected to the feeding bin and pushes out one piece of jewelry each time. In this specific embodiment, the pushing mechanism 22 includes a pushing block 221, a pushing driving mechanism 222, a pushing rod 223, a pushing guide rail 224, and a connecting portion 225.

[0068] The pushing block 221 is arranged at the rear end of the support platform. The upper end of the pushing block is provided with a positioning portion 2211 that can accommodate one piece of jewelry. The positioning portion is disposed opposite to the sliding groove. In this specific embodiment, the positioning portion is a positioning groove that slopes forward and downward. Since the positioning groove slopes forward and downward and the support platform blocks the front of the positioning groove, the jewelry will not fall out of the positioning groove during pushing. The upper surface of the pushing block is an inclined plane that slopes backward and downward, so that except for the jewelry in the positioning groove, the rest of the jewelry will slide off the pushing block.

[0069] The pushing driving mechanism 222 is connected to the pushing block and drives the pushing block to reciprocate between the bottom surface of the feeding bin and the rear end of the sliding groove along the rear side surface of the support platform, so as to push one piece of jewelry into the sliding groove each time.

[0070] The pushing rod 223 is provided to further ensure that only one piece of jewelry is pushed out at a time. At this time, a pushing hole 2132 that penetrates the upper and lower end surfaces of the support platform and is adjacent to the front baffle is also provided on the support platform 213. The pushing hole is located at the lower end of the sliding groove so that the jewelry sliding down along the sliding groove falls on the pushing hole. The pushing rod 223 is inserted into the pushing hole. The pushing rod is connected to the pushing driving mechanism and moves up and down along the pushing hole under the push of the pushing mechanism. The pushing rod moves upward under the push of the pushing driving mechanism to push the jewelry falling on the pushing hole to the pushing port for ejection.

[0071] Of course, the pushing rod can also be not provided, and the jewelry directly falls into the color sorting device through the sliding groove.

[0072] To prevent the jewelry from not being able to be pushed into the color sorting device at the top end of the pushing rod, the upper end of the pushing rod 223 is provided with a push rod groove 2231 that slopes forward and downward and is downwardly concave.

[0073] The pushing guide rail 224 is fixed to the front baffle.

[0074] The connecting part 225 connects the lower ends of the pushing rod and the pushing block. The connecting part is connected to the pushing guide rail and the pushing driving mechanism, and the connecting part moves up and down along the pushing guide rail under the drive of the pushing driving mechanism, so as to drive the pushing rod and the pushing block to move synchronously.

[0075] The setting of the connecting part enables the pushing rod and the pushing block to move synchronously, so that each time a piece of jewelry is pushed into the lower chute and at the same time a piece of jewelry is pushed out to the color sorting device.

[0076] In this specific embodiment, the pushing driving mechanism 222 includes a pushing motor 2221, a pushing runner 2222 and a camshaft 2223.

[0077] The pushing motor 2221 has a pushing output rotating shaft.

[0078] The pushing runner 2222 is fixedly connected to the pushing output rotating shaft;

[0079] The upper end of the camshaft 2223 is hinged to the connecting part, and the lower end is eccentrically hinged to the pushing runner. The pushing motor drives the pushing output rotating shaft to rotate, driving the pushing runner to rotate. Since the camshaft is eccentrically hinged to the pushing runner, the connecting part can be pushed to move up and down, and the pushing block and the pushing rod follow to move up and down.

[0080] In this specific embodiment, the support table 213 includes a convex platform 2133 and a return material inclined surface 2134.

[0081] The convex platform 2133 is located in the center of the support table. The upper end of the convex platform is inclined forward and downward, and the lower chute 2131 is arranged on the upper end surface of the convex platform;

[0082] The return material inclined surface 2134 is located on both sides of the convex platform and is inclined backward and downward from the front end of the convex platform. The settings of the convex platform and the return material inclined surface can make the jewelry outside the lower chute flow back to the bottom of the pushing bin.

[0083] In the present invention, by providing a loading bin and a pushing mechanism, a support table is arranged on the front side wall of the loading bin, and a downwardly concave lower chute that is inclined forward is arranged at the upper end of the support table; a pushing block and a pushing driving mechanism are arranged on the pushing mechanism, and a positioning part capable of accommodating one piece of jewelry is arranged at the upper end of the pushing block. The pushing driving mechanism is used to push the pushing block to move, so as to push the jewelry in the loading bin up to slide down in the lower chute, so that the pushing mechanism only pushes out one piece of jewelry each time, the loading is in order, and there will be no jamming of materials.

[0084] The color sorting device 3 receives the jewelry pushed out by the pushing mechanism, detects the jewelry, pushes out one piece of detected jewelry each time, and issues a color sorting signal according to the detection result.

The color sorting discharge hole 312 is mainly used to allow the jewels to enter the sorting device from the color sorting device. The color sorting feed groove 313 is used to receive the jewels pushed out from the feeding device and allow the jewels to enter the color sorting groove. The color sorting groove has a color sorting position 314. The color sorting groove 311 is mainly used to accommodate the jewels so that the color sorting rotary pushing device can push the jewels to the color sorting position and the discharge hole.

[0087] In order to keep the jewels stationary at the color sorting position during detection, the frame is inclined downward toward the side of the color sorting position, so that the jewels can remain stationary at the color sorting position with the cooperation of the push plate.

[0088] There are multiple color sorting seat support columns 32. The color sorting support columns are fixed to the frame, and the color sorting seat is supported on the color sorting seat support columns. In this specific embodiment, the color sorting seat support columns 32 include four.

[0089] The color sorting rotary pushing device 33 is rotatably connected to the color sorting seat relatively. It mainly pushes the jewels entering the color sorting groove from the color sorting feed groove 313 to the color sorting position for color sorting and pushes the color-sorted jewels to the color sorting discharge hole, so that the jewels enter the sorting device from the color sorting discharge hole.

[0090] The color sorting rotary pushing device 33 includes a plurality of push plates 331 located on the color sorting groove and evenly distributed along the axis of the color sorting rotary pushing device. The push plates 331 are used to push the jewels.

[0091] In this specific embodiment, the push plates 331 are inclined forward and downward to facilitate pushing the jewels more conveniently.

[0092] In this specific embodiment, the color sorting rotary pushing device 33 further includes a color sorting shaft 332 connected to the color sorting driving motor 35 and a color sorting disk 333 fixedly connected to the color sorting shaft. The push plates 331 are fixedly connected to the color sorting disk 333. Color sorting disk support balls 334 are arranged between the color sorting disk and the color sorting seat, and the color sorting disk is supported on the color sorting seat by the color sorting disk support balls.

[0093] The setting of the color sorting disk support balls not only plays a supporting role, but also facilitates rotation and can prevent the color sorting disk from tilting during movement.

[0094] A shaft platform 3321 located below the color sorting disk is provided on the color sorting shaft 332, and shaft platform ball bearings 335 are arranged between the upper end surface of the shaft platform and the bottom surface of the color sorting seat. The arrangement of the shaft platform ball bearings can further prevent the color sorting disk from tilting during movement.

[0095] The color sorting lens 34 is arranged above the color sorting groove and faces the color sorting position. The color sorting lens detects the jewelry at the color sorting position and issues a color sorting signal according to the detection result.

[0096] The output shaft of the color sorting drive motor 35 is fixedly connected to the color sorting rotary pushing device. The color sorting drive motor drives the color sorting rotary pushing device to rotate and controls the push plate to push one piece of inspected jewelry to the color sorting discharge hole each time to discharge the jewelry.

[0097] In order to detect the color of the jewelry and the defects inside the jewelry on the color sorting device, a light-transmitting plate 3111 and a light-impermeable plate 3112 are arranged adjacent to each other at the color sorting position of the color sorting groove 311. The bottom light source 36 is arranged below the color sorting groove and faces the light-transmitting plate, so that the light emitted by the bottom light source can pass through the jewelry from the bottom, facilitating the detection of the defects inside the jewelry. The arrangement of the light-impermeable plate and the light-transmitting plate enables the color sorting lens to detect the color and internal defects of the jewelry in sequence, and the color and internal defects of the jewelry are detected at one time on the color sorting disk, improving the detection efficiency.

[0098] The top light source 37 is arranged below the color sorting lens, and a top light source through hole 371 is provided in the center of the top light source. The color sorting lens faces the top light source through hole. The top light source is mainly used to illuminate the jewelry to facilitate the color sorting lens 34 to detect the color of the jewelry.
