Figure 2 The attached diagram serves as a reference for direction. Figure 2 In the diagram, the direction perpendicular to the view paper and facing outwards is the upward direction, the direction perpendicular to the view paper and facing inwards is the downward direction, the direction along the view paper and upwards is the backward direction, the direction along the view paper and downwards is the forward direction, the direction along the view paper and to the right is the right direction, and the direction along the view paper and to the left is the left direction.

[0062] like Figure 1 and Figure 2 As shown, this utility model provides a dual-cart sorting mechanism 1, which includes a first component, a second component, and a translation track 11.

[0063] The first component includes a first sorting trolley 121 and a first translation transmission unit. The first sorting trolley 121 is movably mounted on the translation track 11 via the first translation transmission unit. The second component includes a second sorting trolley 131 and a second translation transmission unit. The second sorting trolley 131 is movably mounted on the translation track 11 via the second translation transmission unit. Along the extending direction of the translation track 11, a picking station 6 is provided at a non-end position of the translation track 11 for the first sorting trolley 121 and the second sorting trolley 131 to pick up items. The picking station 6 is distributed along the travel distance of the first sorting trolley 121 and the second sorting trolley 131 along the translation track 11, such that the travel distances of the first sorting trolley 121 and the second sorting trolley 131 overlap at the picking station 6. Figure 5 and Figure 6 It is known that the picking station 6 is equipped with a feeding and packaging mechanism 3 and a lifting and conveying mechanism 4. During operation, the feeding and packaging mechanism 3 supplies materials to the lifting and conveying mechanism 4, which then moves up and down to distribute the materials to the first sorting trolley 121 and the second sorting trolley 131. The first translational transmission unit and the second translational transmission unit respectively drive the first sorting trolley 121 and the second sorting trolley 131 to move along the translational track 11, so that the materials can quickly reach any designated position located in the extension direction of the translational track 11. This arrangement helps to improve the sorting efficiency of the sorting mechanism.

[0064] The following are four embodiments of the sorting mechanism of this utility model:

[0065] Example 1

[0066] To ensure the smooth movement of the sorting trolley and prevent it from tilting or swaying during movement, the translation track 11 in Embodiment 1 is a horizontal track, and there are two of them: a first translation track 111 and a second translation track 112. The first translation track 111 and the second translation track 112 are parallel to each other and are arranged opposite each other along their horizontal width direction (i.e., the front-to-back direction). The first translation transmission unit and the second translation transmission unit are arranged between the two translation tracks 11. Those skilled in the art can choose different shapes of the translation tracks 11 as needed. The translation track 11 can be a straight track extending in the left-right direction or a curved track.

[0067] Along the horizontal width of the translation track 11, the front sides of the first sorting trolley 121 and the second sorting trolley 131 are movably mounted on the second translation track 112, while the rear sides of the first sorting trolley 121 and the second sorting trolley 131 are movably mounted on the first translation track 111. Because the rear sides of the first sorting trolley 121 and the second sorting trolley 131 are limited and supported by the first translation track 111, and the front sides of the first sorting trolley 121 and the second sorting trolley 131 are limited and supported by the second translation track 112, they will not tip over forward or backward during movement, maintaining stability during long-term operation. The first translation transmission component 122 and the second translation transmission component 132 are disposed between the two translation tracks 11, both located simultaneously on the front side of the first translation track 111 and the rear side of the second translation track 112.

[0068] Along the horizontal width direction of the translation track 11, the first translation transmission unit includes two first translation transmission components 122 that are symmetrically distributed relative to the first sorting trolley 121 and connected to the first sorting trolley 121, and the second translation transmission unit includes two second translation transmission components 132 that are symmetrically distributed relative to the second sorting trolley 131 and connected to the second sorting trolley 131.

[0069] The arrangement order of the second translation drive 132 and the two first translation drive 122 between the two translation tracks 11 can take several forms. One arrangement is that the two second translation drive 132 are positioned between the two first translation drive 122. Another arrangement is that the two first translation drive 122 and the two second translation drive 132 are staggered along the width direction of the translation track 11.

[0070] In this embodiment of the dual-cart sorting mechanism 1, the two translational transmission units will not interfere with each other during installation and use, and allow the two sorting carts to move simultaneously along the same translational track 11, which can effectively improve sorting efficiency; at the same time, it can also provide stable support for the sorting carts, avoiding the connection position between the translational transmission component and the sorting cart being too concentrated at the end of the sorting cart, which could cause the end of the sorting cart not connected to the translational transmission component to tilt downward.

[0071] Translational transmission units come in various forms.

[0072] The first type of translational transmission unit includes a translational driving wheel, a translational driven wheel, and a translational transmission component. The translational driven wheel and the lifting driving wheel can be pulleys, gears, or sprockets, while the translational transmission component can be a rack, rope, belt, or chain, or other transmission component that can convert the rotational motion of the wheel into translational motion.

[0073] Correspondingly, the first component includes a first sorting cart 121, a first translation drive source 123, and a first translation transmission unit. The first translation transmission unit includes two first translation drive wheels, two first translation driven wheels, and two first translation transmission members 122. The two translation drive wheels are arranged one after the other on the same first synchronous shaft 1231 extending horizontally along the translation track 11. Simultaneously, the two first translation driven wheels are arranged opposite each other, making the two first translation transmission members 122 parallel to each other. The first sorting cart 121 is connected between the two first translation transmission members 122, and the two first translation transmission members 122 are symmetrically distributed about the first sorting cart 121. One end of the first synchronous shaft 1231 is connected to the first translation drive source 123 and rotates under the drive of the first translation drive source 123, driving the first sorting cart 121 connected to the first translation transmission members 122 to move along the translation track 11. Similarly, the second translation transmission unit includes two second translation drive wheels, two second translation driven wheels, and two second translation transmission components 132. The two second translation drive wheels are arranged one after the other on the same second synchronous shaft 1331, while the two second translation driven wheels are arranged opposite each other, so that the two second translation transmission components 132 are arranged parallel to each other. The second sorting cart 131 is connected between the two second translation transmission components 132, and the two second translation transmission components 132 are symmetrically distributed about the second sorting cart 131. One end of the second synchronous shaft 1331 is connected to the second translation drive source 133 and rotates under the drive of the second translation drive source 133, driving the second sorting cart 131 connected to the second translation transmission component 132 to move along the translation track 11.

[0074] A picking station 6 is provided in the middle of the translation track 11 for the first sorting trolley 121 and the second sorting trolley 131 to pick up items. The two ends of the translation track 11 in its extension direction are the first track end and the second track end, respectively. The first synchronous shaft 1231 and the first translation drive wheel on it are located at the first track end (i.e., the left end) of the translation track 11, and the first translation driven wheel is located at the end of the picking station 6 away from the first track end (i.e., the right end of the picking station 6). The second synchronous shaft 1331 and the second translation drive wheel on it are arranged at the second track end (i.e., the right end) of the translation track 11, and the second translation driven wheel is located at the end of the picking station 6 away from the second track end (i.e., the left end of the picking station 6). That is, the movement strokes of the first sorting trolley 121 and the second sorting trolley 131 have an overlapping section at the picking station 6.

[0075] The second type of translation transmission unit is a ball screw. The translation transmission component is a screw extending parallel to the translation track 11. The screw is connected to the sorting trolley through a nut.

[0076] Correspondingly, the first component includes a first sorting cart 121, a first translation drive source 123, and a first translation transmission unit. The first translation drive source 123 drives the first translation transmission component to rotate, and drives the first sorting cart 121 to move along the translation track 11 via a first nut. The second component includes a second sorting cart, a second translation drive source, and a second translation transmission unit. The second translation drive source drives the second translation transmission component to rotate, and drives the second sorting cart to move along the translation track 11 via a second nut.

[0077] Example 2

[0078] The difference between Embodiment 2 and Embodiment 1 is that, along the horizontal width direction of the translation track 11, the first translation transmission unit includes two first translation transmission components 122 symmetrically distributed relative to and connected to the first sorting cart 121, and the second translation transmission unit includes a second translation transmission component 132 centrally distributed relative to and connected to the second sorting cart 131. The two first translation transmission components 122 and the second translation transmission component 132 are all located between the two translation tracks 11, and the second translation transmission component 132 is disposed between the two first translation transmission components 122.

[0079] Example 3

[0080] The difference between Embodiment 3 and Embodiment 1 is that the first translational transmission unit includes a first translational transmission component 122 connected to the first sorting trolley 121, and the second translational transmission unit includes a second translational transmission component 132 connected to the second sorting trolley 131. The first translational transmission component 122 and the second translational transmission component 132 are both located between two translational tracks 11, and the first translational transmission component 122 and the second translational transmission component 132 are spaced apart along the horizontal width direction of the translational track 11.

[0081] Example 4

[0082] like Figure 3 As shown, the difference between Embodiment 4 and Embodiment 1 is that Embodiment 4 only has one translation track 11, which is a horizontal track. The first sorting cart 121 and the second sorting cart 131 are movably mounted on the translation track 11. The first translation transmission unit includes a first translation transmission component 122 connected to the first sorting cart 121, and the second translation transmission unit includes a second translation transmission component connected to the second sorting cart. The first translation transmission component 122 and the second translation transmission component are arranged on the same side or different sides of the translation track 11 along the horizontal width direction. When the first translation transmission component 122 and the second translation transmission component are arranged on the same side of the translation track 11, they are spaced apart and do not interfere with each other.

[0083] like Figure 4 As shown, the first sorting trolley 121 in embodiments one to four above includes a trolley support 1211, two rollers on the trolley support 1211, and a trolley conveyor belt 1212 between the two rollers. The rollers rotate under the drive of a rotary drive source, or the rollers are electric rollers. When the rollers rotate, they can drive the trolley conveyor belt 1212 to move forward or backward.

[0084] Furthermore, in the above embodiments one to three, along the horizontal width direction of the translation track 11, a plurality of translation wheels 1213 are provided on both the front and rear sides of the first sorting trolley 121. The translation wheels 1213 are set in the grooves on the translation track 11 and can travel along the translation track 11, so that the first sorting trolley 121 can be movably installed on the two translation tracks 11.

[0085] The structure of the second sorting cart 131 is exactly the same as that of the first sorting cart 121, and will not be described again here.

[0086] like Figure 5 and Figure 6As shown, this utility model also provides an automatic sorting device, which includes a feeding and packaging mechanism 3, a lifting and conveying mechanism 4, and a frame 2. Multiple aforementioned double-cart sorting mechanisms 1 are spaced apart along the vertical direction in the frame 2, and a material discharge chute 5 is installed on each of the front and rear sides of the frame 2. The feeding and packaging mechanism 3 is located at the picking station 6, near the middle of the translation track 11 and in front of the frame 2. The lifting and conveying mechanism 4 is located between the feeding and packaging mechanism 3 and the frame 2.

[0087] Specifically, such as Figure 7 As shown, the feeding and packaging mechanism 3 includes a packaging platform support 32 and a packaging platform 31 installed on the packaging platform support 32. The packaging platform 31 includes two packaging rollers and a packaging conveyor belt 311 disposed between the two packaging rollers. The packaging conveyor belt 311 rotates continuously under the drive of the motor and can transport materials in the direction of the lifting and conveying mechanism 4.

[0088] like Figure 8 As shown, the lifting and conveying mechanism 4 includes a fixed frame 42, which is rectangular in shape. A lifting drive source 43 is located at the top of the fixed frame 42, driving a lifting synchronous shaft 431 to rotate. Two lifting drive wheels are mounted on the lifting synchronous shaft 431, and two lifting driven wheels are located at the bottom of the fixed frame 42. A lifting transmission component 44 is located between the lifting drive wheels and the lifting driven wheels on the same side. The lifting frame 41 is connected between the two lifting transmission components 44, and a lifting trolley 45 is fixedly connected within the lifting frame 41. The lifting trolley 45 has a structure similar to a sorting trolley, including a trolley support, two rollers mounted on the trolley support, and a trolley conveyor belt positioned between the two rollers. When the lifting drive source 43 drives the lifting synchronous shaft 431 to rotate, it simultaneously drives the lifting frame 41 and the lifting trolley 45 positioned between the two lifting transmission components 44 to perform lifting movements.

[0089] To improve work efficiency, two side-by-side feeding platforms 31 are provided on the feeding platform support 32 of the feeding mechanism 3. A lifting conveyor mechanism 4 is correspondingly provided on the rear side of each feeding platform 31, with the two lifting conveyor mechanisms 4 arranged side-by-side. The feeding platform 31 on the left supplies materials to the first sorting cart 121 in the dual-cart sorting mechanism 1 via the lifting conveyor mechanism 4, while the feeding platform 31 on the right supplies materials to the second sorting cart 131 in the dual-cart sorting mechanism 1 via the lifting conveyor mechanism 4. With this arrangement, the feeding mechanism 3 can simultaneously supply materials to both sorting carts in each dual-cart sorting mechanism 1, facilitating simultaneous operation of the two sorting carts and significantly reducing the sorting time.

[0090] When the automatic sorting device is working, the feeding and packaging mechanism 3 supplies materials to the lifting and conveying mechanism 4. The lifting and conveying mechanism 4 moves up and down to distribute the materials to the first sorting trolley 121 and the second sorting trolley 131 in the double trolley sorting mechanism 1 located at different heights. The first translation transmission unit and the second translation transmission unit respectively drive the first sorting trolley 121 and the second sorting trolley 131 to move left and right along the translation track 11, so that the materials can quickly reach any designated position in the extension direction of the translation track 11. Then the sorting conveyor belt of the sorting trolley moves forward or backward, so that the materials enter the unloading chute 5 to complete the unloading.

[0091] The structural forms of the aforementioned translational drive source, lifting drive source, and rotary drive source are not limited and can be stepper motors or servo motors. The aforementioned lifting drive wheel and lifting driven wheel can be pulleys, gears, or sprockets, while the lifting transmission components can be racks, ropes, belts, or chains, etc., that can convert the rotational motion of the wheels into translational motion.

[0092] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
