[0003] To improve the efficiency and flow rate of sorting units, existing automated sorting and distribution equipment is designed with a three-dimensional orientation. One existing technology provides a sorting device comprising a circular track and a sorting mechanism mounted on the circular track. The sorting mechanism includes a lifting frame that can move along the sorting track and a loading platform that can be lifted and lowered on the lifting frame. Through its movement along the sorting track and the lifting and lowering of the loading platform on the lifting frame, the sorting mechanism enables the lifting platform to sort and distribute any box from a multi-layer shelf.

[0004] To improve the operational reliability of automated sorting and distribution equipment, some existing track-type sorting systems have a frame surrounding the sorting track to prevent workers from entering the working area of ​​the sorting mechanism. The frame is equipped with a loading window for workers to place goods onto the loading platform. However, because the sorting mechanism is in motion during the loading process, the operation of the sorting mechanism may cause scrapes to workers' hands, resulting in lower loading safety.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0040] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0043] This embodiment provides a sorting device that can automatically sort and distribute items, improve sorting efficiency and flexibility, and enhance sorting reliability.

[0044] like Figure 1 and Figure 2 As shown, the sorting equipment provided in this embodiment includes a track sorting module, a shelf 400, and a control system. The track sorting module includes a sorting track 200 and a sorting mechanism 100 running along the sorting track 200. A shelf 400 is provided on the outer side of the sorting track 200, and multiple rows of sorting containers 401 are spaced apart along the height direction on the shelf 400. Each row of sorting containers 401 includes multiple sorting containers 401 arranged horizontally side-by-side. The sorting mechanism 100 can sort goods into any sorting container 401. The control system is communicatively connected to the sorting mechanism 100 to control the sorting mechanism 100 to move the goods it carries along the sorting track 200 to the target sorting position and then unload them into the target sorting container 401, based on the goods sorting information.

[0045] In this embodiment, the sorting track 200 is a racetrack-shaped track, with its length direction along a first direction and its width direction along a second direction. That is, the sorting track 200 includes two straight track segments arranged opposite each other and spaced apart in the second direction, and two arc-shaped track segments connecting the two ends of the two straight track segments. The straight track segments extend along the first direction. The sorting mechanism 100 reciprocates along the sorting track 200. In other embodiments, the sorting track 200 may also be a circular track of other shapes.

[0046] like Figure 2 and Figure 5 As shown, the sorting mechanism 100 includes a mounting column 101, a loading platform 102, and a lifting drive assembly 103. The loading platform 102 is slidably mounted on the mounting column 101 in a vertical direction. The lifting drive assembly 103 drives the loading platform 102 to move up and down along the mounting column 101 to achieve sorting of the loading platform 102 to any level of the sorting container 401. A translation drive assembly 104 is provided on the sorting mechanism 100, which drives the sorting mechanism 100 to move along the sorting track 200.

[0047] It is worth noting that in this embodiment, the specific structures of the sorting track 200, the shelf 400 and the sorting mechanism 100 can all be set with reference to the structures in existing sorting equipment. This is not the focus of the improvement of this utility model, and this utility model does not limit or elaborate on it.

[0048] like Figure 2 and Figure 3 As shown, in this embodiment, the main frame includes two end frames 302 that are opposite to each other and spaced apart in the first direction and a side frame 301 connected between the two end frames 302. There are two side frames 301 spaced apart in the second direction. The two side frames 301 are arranged corresponding to the straight track section of the sorting track 200. The two end frames 302 are respectively arranged around the two ends of the arc track section of the sorting track 200. The sorting area is arranged corresponding to the side frame 301.

[0049] The side frame 301 includes multiple grid components 3011 spaced apart in the height direction. Each grid component 3011 has multiple discharge troughs 30111 arranged side by side along a first direction. The multiple discharge troughs 30111 are correspondingly arranged with multiple sorting containers 401, and the discharge troughs 30111 face the sorting containers 401 from top to bottom. The upper opening of the discharge trough 30111 forms a sorting grid, and the lower opening of the discharge trough 30111 faces the opening of the corresponding sorting container 401. Items unloaded from the sorting mechanism 100 fall into the discharge troughs 30111 through the sorting grids, and then into the target sorting container 401 through the discharge troughs 30111, thereby simplifying the docking between the sorting container 401 and the sorting mechanism 100.

[0050] like Figure 4 and Figure 5 As shown, the end frame 302 includes an end enclosure 3021 and a shield 3022 mounted on the end enclosure 3021. The end enclosure 3021 is generally U-shaped with flared ends and connected to two side frames 301 at both ends, which facilitates the wrapping of the end of the sorting track 200 by the end frame 302 while reducing the footprint of the end frame 302. The shield 3022 is connected to the end enclosure 3021 to protect the end of the sorting track 200. Furthermore, the end enclosure 3021 includes a door frame with an inspection door 3026 installed thereon. The inspection door 3026 can be opened or closed, allowing personnel to enter the interior of the rack 300 through the inspection door 3026 to inspect the goods track sorting module and clean up items that have fallen inside the rack 300.

[0051] like Figures 5 to 8 As shown, to improve the safety and reliability of the sorting equipment, the sorting equipment also includes a frame 300. The frame 300 includes a main enclosure that encloses a sorting work area. The track sorting modules are all located within the sorting work area to shield and protect them, preventing workers from entering the working area of ​​the sorting mechanism 100 and causing collisions. At least one side of the frame 300 has a sorting area, and a shelf 400 is located at the sorting area.

[0052] Sorting areas are provided on both sides of the frame 300 along the second direction, and shelves 400 are provided one-to-one with the sorting areas to increase the number of sorting containers 401, thereby improving the sorting capacity and efficiency of the sorting equipment. Furthermore, two or more shelves 400 are arranged side by side on both sides of the sorting track 200 along the corresponding extension direction to reduce the length of a single shelf 400 and reduce the processing difficulty and processing cost of a single shelf 400.

[0053] To facilitate the loading of items into the sorting mechanism 100, a loading window 3023 is provided on the main frame. The sorting mechanism 100 can be positioned to correspond with the loading window 3023, allowing workers to place items to be sorted onto the loading platform 102 through the loading window 3023. To improve loading safety, in this embodiment, a protective member 303 protrudes from the inner side of the main frame, preventing the loading platform 102 of the sorting mechanism 100 from being positioned horizontally and directly opposite the loading window 3023.

[0054] The rack 300 and sorting equipment provided in this embodiment, by setting a protective component 303 on the inner side of the main frame, the protective component 303 stops the loading platform 102 of the sorting mechanism from running to be horizontally aligned with the loading window 3023, which can prevent the workers' hands from being scratched or injured by the loading platform 102 during the loading process, thus improving the safety of loading operations.

[0055] Specifically, before the sorting mechanism 100 moves along the preset travel direction to the loading window 3023, the loading platform 102 is controlled to descend to the lower side of the loading window 3023, so as to satisfy the user's ability to place the items to be sorted on the loading platform 102 while avoiding the loading platform 102 from scratching the staff's hands when it moves.

[0056] A loading platform 308 is located near the loading window 3023 on the main frame. The loading platform 308 is used to place items to be sorted. In one embodiment, a handling robot can be used to transport the items to be sorted to the loading platform 308 and unload them onto the loading platform 308. In another embodiment, a sorting conveyor line can be provided, which is connected to the loading platform 308 or the loading platform 308 forms part of the sorting conveyor line. The sorting conveyor transports the items to be sorted onto the loading platform 308.

[0057] A barcode scanner 310 is installed on the loading platform 308. The barcode scanner 310 is used to scan the label code on the items to be sorted in order to identify the sorting information of the items. The barcode scanner 310 is communicatively connected to the control system. The control system identifies the target sorting container 401 based on the sorting information obtained by the barcode scanner 310, and controls the running trajectory of the sorting mechanism 100 that receives the items to be sorted, so that the sorting mechanism 100 carries the items to the target sorting container 401.

[0058] The control system includes a control cabinet 600 located outside the rack 300 and a display screen 500 located at the end frame 302. The display screen 500 is communicatively connected to the control cabinet 600 and can display sorting information for staff to verify. It is worth noting that the display screen 500 can also display the operating status of the sorting equipment. The display settings of the display screen 500 can refer to existing displays; this is not the focus of this utility model and will not be elaborated upon here.

[0059] The loading window 3023 includes side edges spaced circumferentially along the main frame. Protective members 303 include side guards 303 located at two of the side edges. Each guard 303 includes a vertically extending side guard beam 3031, which is located at least one of the two side edges upstream of the sorting mechanism 100 in a preset travel direction. This arrangement allows the loading platform 102 to be moved laterally along the preset travel direction to face the loading window 3023, at least by stopping it with the side guard beam 3031, thus ensuring loading safety and reliability.

[0060] In this embodiment, two side protection beams 3031 are provided, and the two side protection beams 3031 are respectively provided at the two side edges. By providing two side protection components 303, the loading platform 102 of the sorting mechanism 100 located downstream of the loading window 3023 can be prevented from retreating to face the loading window 3023 due to accident or other circumstances, thereby further improving the safety of the sorting equipment.

[0061] The protective component 303 also includes a lower protective beam 3032 located below the upper loading window 3023, and / or an upper protective beam 3033 located above the upper loading window 3023. By providing the lower protective beam 3032, the loading platform 102 located below the upper loading window 3023 can be prevented from rising upwards to be directly opposite the upper loading window 3023; by providing the upper protective beam 3033, the loading platform 102 located above the upper loading window 3023 can be prevented from descending to be directly opposite the upper loading window 3023.

[0062] Both the upper protective beam 3033 and the lower protective beam 3032 extend laterally. The extension length of the upper protective beam 3033, the lower protective beam 3032, and the side protective beam 3031 is greater than or equal to the length of the corresponding side to effectively ensure the protective effect. The upper and lower ends of the side protective beam 3031 are connected to the upper protective beam 3033 and the lower protective beam 3032 respectively to enhance the overall protective effect.

[0063] To further enhance loading safety, a grating detection component 305 is installed at the loading window 3023. This component detects whether a worker is performing a loading operation, thus assisting in determining whether there are items to be sorted on the loading platform 102. Specifically, the grating detection structure includes a grating emitter 3051 and a grating receiver 3052, which are respectively positioned on opposite sides of the loading window 3023. The grating emitter 3051 emits a detection beam towards the grating receiver 3052. Based on the received detection beam, the receiver determines whether the beam is partially blocked, thereby determining whether the worker's hand has entered the loading window 3023 to load an item. This grating detection component 305 offers high detection accuracy, and by detecting light obstruction, it can detect both the start and end of loading operations, improving detection reliability.

[0064] Specifically, when a worker's hand passes through the detection grating, the grating detection component 305 switches from an initial signal to a trigger signal; when the worker puts down an item and exits the loading window 3023, the grating detection component 305 switches from a trigger signal back to an initial signal. By changing the signal of the grating detection component 305, it is determined whether loading has started and ended, thus enabling the sorting device 100 to move to the loading window 3023 at a relatively slow speed when there is a supply, and to pass through the supply area at a relatively fast speed when there is no supply.

[0065] In this embodiment, the grating receiver 3052 and the grating emitter 3051 are respectively disposed at two side protective beams 3031. Further, each side protective beam 3031 is a U-shaped beam, comprising a vertical beam and a horizontal beam connecting both ends of the vertical beam. The horizontal beam is connected to the end frame 302. The side protective beams 3031 and the end frame 302 together form an installation space. The grating receiver 3052 and the grating emitter 3051 are both installed on the side of the corresponding vertical beam facing the end frame 302. This arrangement protects the grating emitter 3051 and the grating receiver 3052, effectively preventing them from being bumped by the sorting mechanism 100, thus improving the safety of the grating detection assembly 305. Specifically, the horizontal beam is connected to the end frame 3021 to improve the connection stability and reliability of the side protective beams 3031.

[0066] In other embodiments, the grating receiver 3052 and the grating emitter 3051 may be respectively disposed at the upper protective beam 3033 and the lower protective beam 3032.

[0067] Since there may be a problem that the items to be sorted may fall off the loading platform 102 during the loading process, in this embodiment, a recycling window 3024 is provided on the main frame, and a drop-off support frame 304 is provided on the inner side of the main frame. The drop-off support frame 304 is located below the loading window 3023, and the drop-off support frame 304 has a recycling guide surface that is inclined from top to bottom toward the recycling window 3024, and the lower end of the recycling guide surface extends to the recycling window 3024.

[0068] By providing a drop support frame 304, items falling from the loading platform 102 at the loading position can be supported. By providing a recovery guide surface and a recovery window 3024, items falling onto the recovery guide surface can slide down to the recovery window 3024 and then slide out of the rack 300, facilitating the recovery of fallen items and preventing workers from entering the rack 300 to retrieve them, thus improving the operational safety and item recovery efficiency of the sorting equipment. In this embodiment, the recovery window 3024 is located below the loading window 3023 to facilitate easy retrieval of fallen items by workers.

[0069] To simplify the structure of the drop-off support frame 304, the drop-off support frame 304 includes a drop-off guide ramp 3041 and a connecting frame portion 3042 connected to the lower side of the drop-off guide ramp 3041. The drop-off guide ramp 3041 extends from top to bottom toward the end frame 302. The lower end of the connecting frame portion 3042 is supported on the ground or connected to the bottom frame structure of the frame 300. The upper side of the drop-off guide ramp 3041 forms a recovery guide surface. The left and right sides of the drop-off guide ramp 3041 are folded upward to form side baffle portions 3043 to prevent items from falling from the sides of the drop-off support frame 304 into the frame 300.

[0070] Furthermore, the rack 300 includes a bottom frame 309 connected to the inner side of the lower end of the end frame 3021. Multiple support legs are connected to the lower end of the bottom frame 309 to increase the stability and reliability of the rack 300. The lower end of the connecting frame portion 3042 is connected to the bottom frame 309. The extension direction of the drop-off support member in the first direction is greater than the length of the loading window 3023 to increase the load-bearing area and ensure that items falling from the loading platform 102 land on the drop-off support frame 304 as much as possible. Furthermore, in the first direction, the drop-off support frame 304 extends from one end of the end frame 302 to the other end.

[0071] Because the end frame 302 has a flared U-shaped structure, a bottom frame 309 is provided on three sides of the U-shaped structure. The drop guide ramp 3041 includes a first guide plate portion and a second guide plate portion connected along a first direction, wherein the second guide plate portion is located on the side of the first guide plate portion away from the side frame 301, that is, at the end of the second guide plate portion near the main frame. The width of the first guide plate portion in the second direction is smaller than the width of the second guide plate portion in the second direction, thereby making the drop guide ramp 3041 relatively narrow in the part near the sorting track 200 to avoid the sorting track 200 and the sorting mechanism 100, and wider in the part away from the sorting track 200 to increase the bearing area.

[0072] Furthermore, the width of the first guide plate portion in the second direction gradually increases along the direction toward the second guide plate portion, and the side of the first guide plate portion facing the sorting track 200 is an arc-shaped edge, so as to better avoid the sorting track 200 and the sorting mechanism 100 while increasing the bearing area of ​​the first guide plate portion.

[0073] Furthermore, the end frame 302 is also provided with an abnormality slot 3025, and a unloading plate extends outward from the lower edge of the abnormality slot 3025. If the items on the loading platform 102 of the sorting mechanism 100 are not sorted normally due to the sorting container 401 being full, the items on the loading platform 102 not being scanned and identified, or other reasons, the sorting mechanism 100 can unload the items through the abnormality slot 3025 to avoid abnormal items remaining on the loading platform 102 and occupying the sorting mechanism 100, thus better ensuring the sorting efficiency of the sorting mechanism 100. A recycling bin 700 is provided on the outside of the end frame 302 below the unloading plate for temporary storage and recycling of abnormally sorted items.

[0074] The loading window 3023 is located outside the sorting area to avoid interference with the shelf 400. Specifically, the loading window 3023 is located on the end shelf 302, and the loading platform 308 is connected to the outside of the end shelf 302. Preferably, both end shelves 302 are provided with loading platforms 308, and the two loading platforms 308 are located on opposite sides of the sorting track 200. By providing two loading platforms 308, the loading positions can be increased, loading efficiency can be improved, and thus sorting efficiency can be improved.

[0075] Furthermore, each loading station 308 is positioned close to a sorting area upstream of the sorting mechanism 100 in the preset travel direction. This means that the sorting mechanism 100 reaches the loading position after passing through one sorting area, and then travels a certain distance to reach another sorting area. This arrangement facilitates the detection of the loading status using the distance between the loading position and the downstream sorting area, improving loading reliability and control accuracy. Specifically, the loading position corresponds to the connection point between the straight track section and the curved track section.

[0076] A load detection device 306 is installed inside the end frame 302, and the load detection device 306 is communicatively connected to the control system. The load detection device 306 is located downstream of the loading window 3023 along the preset travel direction. The load detection device 306 is used to detect whether there are items on the loading platform 102, so as to determine whether the items are stably loaded on the loading platform 102, thereby improving control accuracy.

[0077] The sorting equipment is also equipped with a positioning detection component 307, which is used to detect whether the sorting mechanism 100 has moved to the loading detection position. The positioning detection component 307 is connected to the control system. After the positioning detection component 307 detects that the sorting mechanism 100 has moved to the loading detection position, the control system controls the loading detection device 306 to perform detection, thereby eliminating the need for the loading detection device 306 to be in a detection state at all times, reducing detection costs, and improving detection reliability.

[0078] The positioning detection component 307 is preferably configured as a non-contact detection device such as a photoelectric sensor to avoid frictional wear. The loading detection device 306 preferably uses a camera. The camera takes pictures of the loading platform 102 and transmits the pictures to the control system. The control system compares the pictures taken by the camera with pictures of the loading platform 102 without loading to determine whether the loading platform 102 is carrying any items.

[0079] In another embodiment, the positioning detection component 307 may be omitted, and the sorting mechanism 100 may be judged by the stroke of its travel from the initial starting point to determine whether it has reached the loading detection position. In yet another embodiment, the loading detection device 306 may be in a real-time detection state. In yet another embodiment, a pressure detection element or other detection structure may be provided on the loading platform 102 to determine whether there are items on the loading platform 102.

[0080] Specifically, the positioning detection component 307 includes a positioning detection element 3071 and a positioning sensor 3072 that are configured to cooperate. One of the positioning detection element 3071 and the positioning sensor 3072 is configured on the frame 300 and the other is configured on the loading platform 102. When the relative position of the positioning detection element 3071 and the positioning sensor 3072 reaches the point where the positioning sensor 3072 triggers the positioning detection element 3071, it indicates that the loading platform 102 has reached the positioning position.

[0081] In this embodiment, the arrival detection element 3071 is disposed on the loading platform 102, that is, each sorting mechanism 100 is provided with an arrival detection element 3071, thereby enabling the identification of the sorting mechanism 100 that has reached the loading detection position by detecting the signal emitted by the arrival detection element 3071. Specifically, the arrival sensing element 3072 is mounted on the side protective beam 3031. In other embodiments, the arrival sensing element 3072 is disposed on the loading platform 102, and the arrival detection element 3071 is disposed on the frame 300, thereby allowing multiple sorting mechanisms 100 to share the same arrival detection element 3071, resulting in lower costs.

[0082] The arrival detection element 3071 is preferably disposed on the side of the loading platform 102 to avoid interfering with the placement of the items to be sorted on the loading platform 102, and also to prevent the items on the loading platform 102 from obstructing the arrival detection element 3072. The arrival detection element 3072 is preferably a sensor sheet.

[0083] This embodiment also provides a control method for a sorting device, the control method including: before the sorting mechanism 100 runs to the loading window 3023, controlling the loading platform 102 to descend below the lower edge of the loading window 3023.

[0084] The control method provided in this embodiment can prevent the loading platform 102 from being directly opposite the loading window 3023 when the sorting mechanism 100 passes through the loading window 3023, thereby avoiding the loading platform 102 from scratching or injuring the hands of the workers and improving the safety and reliability of the sorting equipment.
