Description

Technical Field

[0001] This invention relates to the field of cargo warehousing, specifically to a storage and sorting system without fixed shelves. Background Technology

[0002] In existing technologies, warehousing systems typically employ a combination of containers and fixed racks. This method requires placing goods in containers, then categorizing the containers and placing them on different fixed racks or different areas of those racks. Furthermore, stacker cranes, shuttle cars, and other conveying equipment are essential for the storage, retrieval, and transfer of containers. Therefore, these warehousing systems suffer from problems such as cumbersome racking setup and high costs for racks and conveying equipment.

[0003] Furthermore, when applying such a warehousing system to the apparel industry, multiple garments must be packaged in the same container during transportation and storage, and the garments can only be stacked together inside the container. Specifically, if garments are stacked haphazardly in the container, severe wrinkles will form, requiring smoothing before shipment. If garments are stacked neatly, the process of neatly stacking requires significant manpower and resources; even when neatly stacked, slight wrinkles are still unavoidable. Moreover, since individual storage and transportation are not possible, if garments need to be re-sorted or classified according to their properties, the containers must be opened, and manual inspection and sorting must be performed. Therefore, using such a warehousing system for apparel storage is particularly inconvenient and inefficient in terms of manpower and resources.

[0004] Therefore, rackless warehousing and sorting systems that eliminate the need for fixed shelving and prevent clothing from being stacked have become an urgent need in the apparel warehousing industry. However, rackless warehousing and sorting systems require the classification and storage of clothing. During classification, errors are inevitable, and sometimes it may be necessary to change the storage location of already stored clothing based on actual needs. This new storage location might be a different storage line within the same area as the original location, or it might be in a different area altogether. Solving these classification and storage challenges has become a key development difficulty for rackless warehousing and sorting systems. Summary of the Invention

[0005] This invention was made to solve the above-mentioned problems, and its purpose is to provide a storage and sorting system without fixed shelves.

[0006] This invention provides a shelfless storage and sorting system for sorting and storing goods on carriers. It comprises: m conveying and transfer devices arranged sequentially along the conveying direction of the goods carriers to transfer goods from an upper-level area to a lower-level area; m-1 sorting and storage devices arranged between adjacent conveying and transfer devices for classifying and storing the goods carriers; and at least one transfer return track arranged between two conveying and transfer devices to return goods carriers on the downstream conveying and transfer device to the upstream conveying and transfer device. Each conveying and transfer device includes: an upper-level conveying track composed of random conveying tracks; a lower-level conveying track composed of single-item conveying tracks; and a connecting track connected to both the upper-level and lower-level conveying tracks to guide goods carriers from the upper-level to the lower-level conveying track. m ≥ 2 and m is a positive integer. One end of the transfer return track is connected to the upper-level conveying track of one of the two conveying and transfer devices, and the other end is connected to the lower-level conveying track of the other conveying and transfer device.

[0008] The shelfless storage and sorting system provided by the present invention may also have the following features: the sorting and storage equipment includes at least a plurality of storage lines, each storage line having an upstream storage end and a downstream storage end. The upstream storage end is provided with a diversion component and is connected to the corresponding upstream next-level conveyor track through the diversion component. The downstream storage end is provided with a guide component and is connected to the corresponding downstream upper-level conveyor track through the guide component.

[0009] The shelfless storage and sorting system provided by the present invention may also have the following feature: a blocking component for controlling whether the cargo carrier on the storage line enters the upper-level conveyor track is provided at a position near the downstream storage end of the storage line.

[0010] The storage and sorting system without fixed shelves provided by the present invention may also have the following feature: wherein a first return movement drive mechanism for driving the cargo carrier to return is also provided on the transfer return track.

[0011] The shelfless storage and sorting system provided by this invention may also have the following features: the upper-level conveyor track is composed of a grid-type conveyor track, and the lower-level conveyor track is composed of a hook-type conveyor track. Both the upper-level and lower-level conveyor tracks are closed loop tracks, and the conveying direction of the upper-level conveyor track is opposite to that of the lower-level conveyor track. The cargo carrier contains a hook with an insertion opening. The insertion opening of the hook on the upper-level conveyor track faces inward toward the loop of the upper-level conveyor track, and the insertion opening of the hook on the lower-level conveyor track faces outward toward the loop of the lower-level conveyor track.

[0012] The storage and sorting system without fixed shelves provided by the present invention may also have the following features: the next-level conveying track has a carrying track for carrying goods, the connecting track has an upper-level end and a lower-level end, the upper-level end is provided with a derailment component and is connected to the upper-level conveying track through the derailment component, and the lower-level end is provided with a guide connecting member and is connected to the carrying track through the guide connecting member.

[0013] The storage and sorting system without fixed shelves provided by the present invention may also have the following features: wherein the upper-level conveying track has an upstream track segment portion that is upstream of the off-track component along the conveying direction of the cargo carrier and a downstream track segment portion that is downstream. The upstream track segment portion serves as the upper-level upstream track segment portion, and the downstream track segment portion serves as the upper-level downstream track segment portion. The upper-level upstream track segment portion is set higher than the upper-level downstream track segment portion.

[0014] The non-fixed shelf storage and sorting system provided by the present invention may also have the following features: wherein the next-level conveying track has an upstream track segment portion that is upstream of the guide connecting member along the conveying direction of the cargo carrier and a downstream track segment portion that is downstream. The upstream track segment portion serves as the next-level upstream track segment portion, and the downstream track segment portion serves as the next-level downstream track segment portion. The next-level upstream track segment portion is set higher than the next-level downstream track segment portion, and the position of the off-track component is set higher than the position of the guide connecting member.

[0015] The shelfless storage and sorting system provided by the present invention may also include: an inbound device for storing goods carriers, including at least one goods loading line connected to the upper-level conveyor track of the upstream conveyor transfer device; and an outbound device for discharging goods carriers, including at least one outbound line connected to the lower-level conveyor track of the downstream conveyor transfer device.

[0016] The role and effect of invention

[0017] According to the present invention, the shelfless storage and sorting system includes m conveying and transfer devices and m-1 sorting and storage devices. The conveying and transfer devices include an upper-level conveying track, a lower-level conveying track, and a connecting track. The upper-level conveying track is composed of a random conveying type conveying track, and the lower-level conveying track is composed of a single-item conveying type conveying track. Therefore, after the cargo carrier enters the lower-level conveying track, it can enter the sorting and storage device in the lower-level area for sorting and storage.

[0018] Furthermore, since m conveying and transfer devices are arranged sequentially along the conveying direction of the cargo carrier, and m-1 sorting and storage devices are respectively set between two adjacent conveying and transfer devices, the cargo carrier can be classified and stored at the first level (or stored without classification) after passing through each conveying and transfer device and its adjacent sorting and storage device along the conveying direction. Ultimately, the system can achieve multi-level classification and storage.

[0019] Furthermore, because the system also includes at least one transfer return track, which is located between the two conveying transfer devices, with one end of the transfer return track connected to the upper-level conveying track of one of the two conveying transfer devices and the other end connected to the lower-level conveying track of the other of the two conveying transfer devices, the cargo carrier on the downstream conveying transfer device along the conveying direction can be returned to the upstream conveying transfer device through the transfer return track. This allows the cargo carrier to be re-sorted and stored, improving the flexibility and accuracy of the entire system's sorting and storage.

[0020] Furthermore, the two conveying and transferring devices connected by the transfer return track can be either adjacent or non-adjacent. When the two conveying and transferring devices are arranged adjacently, cargo carriers located on a storage line between the two devices can be re-stored on another storage line in the same area via the transfer return track; when the two conveying and transferring devices are not arranged adjacently, cargo carriers can be re-stored between different storage areas via the transfer return track.

Detailed Implementation

[0040] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments, in conjunction with the accompanying drawings, provide a detailed description of the fixed-shelf storage and sorting system of the present invention.

[0041] <Example>

[0042] Figure 1 This is a schematic diagram of the structure of a warehouse sorting system without fixed shelves in an embodiment of the present invention.

[0043] like Figure 1 As shown, the rackless warehousing and sorting system 100 in this embodiment is a clothing warehousing system that uses rails to transport and store goods (clothing) on ​​cargo carriers (clothing hangers). It includes inbound equipment 101, conveying and transfer equipment 102, sorting and storage equipment 103, transfer and return mechanism 104, and outbound equipment 105.

[0044] There are m conveying and transfer devices 102, and the m conveying and transfer devices 102 are arranged along the conveying direction of the cargo carrier. Figure 1 The solid arrows in the diagram indicate the conveying direction. The sorting and storage devices 103 are set up sequentially (m-1 in number, with each of the m-1 sorting and storage devices 103 positioned between two adjacent conveying and transfer devices 102). m ≥ 2 and m is a positive integer.

[0045] In this embodiment, m = 3. Along the transport direction of the cargo carrier, the three transport and transfer devices 102 are respectively referred to as the first transport and transfer device 102a, the second transport and transfer device 102b and the third transport and transfer device 102c, and the two sorting and storage devices 103 are respectively referred to as the first sorting and storage device 103a and the second sorting and storage device 103b.

[0046] The receiving device 101 is used to receive hangers containing clothing into the warehouse; the first conveying and transfer device 102a is used to transfer the hangers from the receiving device 101 to the first sorting and storage device 103a, which is used to classify and store the hangers; the second conveying and transfer device 102b is used to transfer the hangers from the first sorting and storage device 103a to the second sorting and storage device 103b, which is used to classify and store the hangers; the third conveying and transfer device 102c is used to transfer the hangers from the second sorting and storage device 103b to the outgoing device 105; the outgoing device 105 is used to outgoing the stored hangers.

[0047] The area where the inbound device 101 is located is the area above the area where the first sorting and storage device 103a is located, the area where the first sorting and storage device 103a is located is the area above the area where the second sorting and storage device 103b is located, and the area where the second sorting and storage device 103b is located is the area above the area where the outbound device 105 is located.

[0048] At least one transfer return mechanism 104 is provided and disposed between two conveying transfer devices 102 for returning a clothes hanger on the downstream conveying transfer device 102 to the upstream conveying transfer device 102. In this embodiment, three transfer return mechanisms 104 are provided. The three transfer return mechanisms 104 are respectively designated as the first transfer return mechanism 104a, the second transfer return mechanism 104b, and the third transfer return mechanism 104c. The first transfer return mechanism 104a is disposed between the first conveying and transfer device 102a and the second conveying and transfer device 102b, and is used to return the hangers on the second conveying and transfer device 102b to the first conveying and transfer device 102a; the second transfer return mechanism 104b is disposed between the third conveying and transfer device 102c and the second conveying and transfer device 102b, and is used to return the hangers on the third conveying and transfer device 102c to the second conveying and transfer device 102b; the third transfer return mechanism 104c is disposed between the third conveying and transfer device 102c and the first conveying and transfer device 102a, and is used to return the hangers on the third conveying and transfer device 102c to the first conveying and transfer device 102a. Figure 1 The direction indicated by the dashed arrow in the image is the return direction when the clothes hanger moves back.

[0049] The three conveying and transfer devices 102 have the same structure. The structure of the conveying and transfer device 102 will be described in detail below, taking the first conveying and transfer device 102a as an example.

[0050] Figure 2 This is a three-dimensional structural schematic diagram of the first conveying and transferring device in an embodiment of the present invention; Figure 3 yes Figure 2 Enlarged view of section A of the middle frame.

[0051] like Figures 1 to 3 The first conveying and transfer device 102a shown includes a first upper-level conveying track 21a, a first lower-level conveying track 23a, and a first connecting part 24a.

[0052] The receiving equipment 101 includes at least one goods loading line 22. In this embodiment, multiple goods loading lines 22 are provided. The goods loading line 22 is used to transport the hangers to the first upper-level conveyor track 21a. The specific structure of the goods loading line 22 is prior art and will not be described in detail here.

[0053] like Figure 3 As shown, the hanger 200 in this embodiment includes a hook 201 and a support portion (not shown) for holding clothing. The hook 200 has an insertion opening 201a through which it is hooked onto various conveyor tracks. Although Figure 3 Only the structure of hook 201 is shown in the image; however, those skilled in the art can determine the position of hanger 200 and the position of the garments hanging on hanger 200 based on the position of hook 201.

[0054] The first upper-level conveying track 21a is a closed loop track and is composed of random conveying type conveying tracks. In this embodiment, the random conveying type conveying track is a format type conveying track. The format type conveying track includes a first mounting track 211 and multiple format components 212 whose lower parts cooperate with the hooks 201 of the clothes hanger 200 for carrying and conveying the clothes hanger 200. The format components 212 move on the first mounting track 211 by a pulley system embedded in the first mounting track 211. The specific installation method is prior art and will not be described in detail here. Figure 3 and Figure 4 Only a portion of the formatting components 212 are shown in the figure. In reality, multiple partial formatting components 212 are arranged on the entire closed-loop first mounting track 211 in the same manner as those shown in the figure. A first driving unit (not shown in the figure) for driving the formatting components 212 to move is also provided on the first upper-level conveying track 21a. In this embodiment, the conveying direction of the first upper-level conveying track 21a is clockwise.

[0055] In this embodiment, the opening of the "G"-shaped format component 212 faces outward from the ring of the first upper-level conveyor track 21a. The hook 201, which enters the first upper-level conveyor track 21a via the goods loading line 22, is hooked onto the format component 212 and moves with it. The hook opening 201a of the hook 201 on the first upper-level conveyor track 21a faces inward from the ring of the first upper-level conveyor track 21a.

[0056] Figure 4 yes Figure 3 Enlarged view of section B of the middle frame; Figure 5 yes Figure 4 A schematic diagram of the structure from another viewpoint.

[0057] like Figures 3 to 5 As shown, the first lower-level conveying track 23a is composed of a single-piece conveying track, which in this embodiment is a birdhook-type conveying track. The birdhook-type conveying track includes a plurality of birdhook-type conveying units 61, a guide rail 62, and a support track 63. The guide rail 62 provides support and is a closed ring; the support track 63 is disposed on the guide rail 62 and correspondingly positioned below it, for supporting the clothes hanger 200; the plurality of birdhook-type conveying units 61 are disposed on the guide rail 62 and located above the support track 63. The conveying direction of the first lower-level conveying track 23a is opposite to the conveying direction of the first upper-level conveying track 21a, i.e., counterclockwise.

[0058] The first upper-level conveying track 21a has a first connecting track segment 213 that is adjacent to the first lower-level conveying track 23a and extends downward at an incline. The first connecting track segment 213 forms an angle of 30° to 60° with the horizontal direction; specifically, this angle can be selected based on the available space at the track installation site. In this embodiment, the first connecting track segment 213 forms a 30° angle with the horizontal. The conveying direction on this first connecting track segment 213 is... Figure 3 The direction indicated by the middle arrow D1 is hereinafter referred to as the conveying direction D1.

[0059] The first downstream conveying track 23a has a second connecting track segment 65 that is adjacent to the first connecting track segment 213 and extends downward at an incline. This second connecting track segment 65 is parallel to the first connecting track segment 213. The conveying direction on the second connecting track segment 65 is... Figure 3 The direction indicated by the middle arrow D4 is hereinafter referred to as the conveying direction D4.

[0060] The carrying track 63 is configured as a non-closed loop, having a first end 63a and a second end 63b. In this embodiment, both the first end 63a and the second end 63b are located at the lower part of the second connecting track segment 65. The first end 63a is connected to the first connecting part 24a, thereby allowing the hanger 200 to be received from the first upper-level conveying track 21a from the first connecting part 24a. The second end 63b is located above the first end 63a, with a small gap between them, making the entire carrying track 63 approximately loop-shaped. Furthermore, the portion of the second end 63b near the first end 63a is pointed, allowing the hanger 200 to move smoothly from the second end 63b to the first end 63a, thereby ensuring the loop movement of the hanger 200 on the first lower-level conveying track 23a.

[0061] The first connecting part 24a is disposed between the first upper-level conveyor track 21a and the first lower-level conveyor track 23a, and is used to guide the clothes hanger 200 to slide naturally from the first upper-level conveyor track 21a to the first lower-level conveyor track 23a without relying on any driving structure, solely by gravity. It includes a derailment component 71, a connecting track 72, and a guiding connecting member 73. The connecting track 72 serves as a connecting track for the warehousing storage room.

[0062] Figure 6 yes Figure 3 Enlarged view of section C of the middle frame; Figure 7 This is a three-dimensional structural diagram of the off-track component in an embodiment of the present invention;

[0063] like Figure 6 and Figure 7 As shown, the off-track assembly 71 has an off-track member 711 and a guide transfer member 712.

[0064] The derailment component 711 has an integrally formed mounting part 84 and a derailment part 85. The material of the derailment component 711 is Q235 steel with a white zinc coating, and the overall thickness is 4mm.

[0065] The mounting section 84 includes a fixing plate 841, a vertical connecting plate 842, and a horizontal connecting plate 843. One side of the fixing plate 841 is bent to form the vertical connecting plate 842, the bottom of the vertical connecting plate 842 is bent to form the horizontal connecting plate 843, and the side of the horizontal connecting plate 843 away from the vertical connecting plate 842 is bent to form the off-track section 85.

[0066] The fixing plate 841 is screwed onto the first connecting track section 213 and is mounted on top of the first mounting track 211. In this embodiment, the mounting part 84 is mounted at the middle position of the first connecting track section 213. The first connecting track section 213 is divided into an upstream track section 213a and an upstream downstream track section 213b along the conveying direction D1, based on the mounting position of the mounting part 84.

[0067] The structure formed by the fixing plate 841, the vertical connecting plate 842, and the horizontal connecting plate 843 matches the "G"-shaped format member 61, allowing the format member 61 to pass smoothly without loading the hanger 200. Furthermore, the opening of the mounting part 84 faces outwards from the first upper-level conveyor track 21a.

[0068] The derailment section 85 is located on the side of the first connecting track section 213 near the first next-level conveyor track 23a, that is, outside the loop of the first upper-level conveyor track 21a, and is used to detach the hanger 200 from the first connecting track section 213 to the guide transfer member 712. The side of the derailment section 85 is trapezoidal, and the two base corners of the trapezoid are rounded and extend outward respectively.

[0069] The off-track section 85 has an inclined section 851 that gradually deviates along the conveying direction D1. The inclined section 851 is located at the lower base of a trapezoidal shape, and its extending direction is... Figure 6 The direction shown is D2, which is the deviation from the transfer direction.

[0070] The inclined portion 851 has an inlet end 8511 and an outlet end 8512. The width of the inlet end 8511 is smaller than that of the outlet end 8512. The inlet end 8511 is inserted into the gap between the format member 212 and the hanger 200 hanging on the format member 212, thereby lifting the hanger 200 that has been moved to that position and moving it away from the first connecting track segment 213. The inclined portion 851 also has an offset edge 851a extending in an offset direction, the angle between the extension direction of the offset edge 851a and the extension direction of the transverse connecting plate 843 is α, α is 10° to 20°, and in this embodiment, α is 15°.

[0071] The guide transfer member 712 is used to guide and transfer the hanger 200, which has detached from the off-track section 85, to the connecting track 72. The guide transfer member 712 has a first main guide section 81, an introduction end 82, and an exit end 83.

[0072] The guide transfer member 712 has an introduction end 82, a first main guide section 81, and an exit end 83 that are integrally molded and are made of PA plastic and glass fiber.

[0073] The first main guide section 81 gradually bends along its length toward the first next-level conveyor track 23a, and also gradually bends downwards. Guide protrusions 811 are formed on both sides of the top of the first main guide section 81. The guide protrusions 811 extend along the length of the first main guide section 81 and can match the hanger 200, allowing the hanger 200 to slide smoothly on the first main guide section 81.

[0074] The lead-in end 82 is located at one end of the first main guide section 81, extending along the direction close to the derailment portion 85 and gradually decreasing in width. The lead-in end 82 has a groove 822 provided along the length direction of the first main guide section 81. The groove 822 matches the derailment member 711, and through holes 823 are respectively provided on both side walls. The through holes 823 correspond to the mounting holes of the lead-out end 8512. The lead-out end 8512 is embedded in the groove 822, and is fixed together with the derailment member 711 by bolts passing through the through holes 823 and the mounting holes. Under its own weight, the clothes hanger 200 slides naturally into the guide transfer member 712 after leaving the first connecting track section 213 via the derailment member 711.

[0075] The export end 83 includes an export tray 833, an export limiting plate 834, and an export positioning protrusion 835.

[0076] The export tray 833 is located at the other end of the first main guide section 81 and extends along the extension direction of the first main guide section 81. A fixing hole 833a is provided on the export tray 833. Two export limiting plates 834 are triangular in shape. The two export limiting plates 834 are respectively fixed to the two sides of the export tray 833 along its length.

[0077] One end of the connecting track 72 is connected to the guide transfer member 712 as the upper-level end 721, and the other end is connected to the first end 63a of the carrying track 63 via the turning guide connecting member 73 as the lower-level end 722. The upper-level end 721 is positioned higher than the lower-level end 722, allowing the hanger 200 to slide naturally along the length of the connecting track 72 towards the second connecting track segment 65 by gravity after leaving the guide transfer member 712, with the conveying direction as follows: Figure 3 As indicated by arrow D3 in the diagram, this is referred to as the conveying direction D3.

[0078] The tilt angle of the connecting track 72 is determined based on the total weight of the hanger 200 and the garment, generally between 10° and 60°. When the weight is heavy, this angle needs to be set smaller to avoid excessively fast transport speed; when the weight is light, this angle needs to be set larger to prevent the garment from getting stuck due to resistance during descent. In this embodiment, the total weight is calculated to be 1.5kg, and the angle between the connecting track 72 and the horizontal direction is 20°.

[0079] Figure 8 This is a schematic diagram of the connecting track in an embodiment of the present invention.

[0080] like Figure 8 As shown, the connecting track 72 includes a track body 55, a mounting part 51, and two bushings 52a and 52b. In this embodiment, the track body 55 and the mounting part 51 are integrally formed.

[0081] The track body 55 includes two opposing side support portions 53a and 53b, and a top support portion 54 that is combined with the top portions of the two side support portions 53a and 53b. The top support portion 54 has two inclined portions 501a and 501b that are symmetrically distributed along the length direction, and a planar portion 502 located between the two inclined portions 501a and 501b.

[0082] Mounting section 51 is provided on top support section 54 and has mounting grooves 503a and 503b extending along the length direction of the track body and a connecting positioning groove 504. Mounting grooves 503a and 503b are respectively provided on two inclined sections 501a and 501b. Connecting positioning groove 504 is provided on flat section 502.

[0083] Two bushings 52a and 52b are respectively installed in and fitted into two mounting slots 503a and 503b. The tops of the bushings 52a and 52b protrude upwards from the mounting slots 503a and 503b, respectively, allowing the clothes hanger 200 to be stably mounted on the two bushings 52a and 52b and to move smoothly along the length of the track body 55. The bushings have an inverted U-shaped cross-section and are made of plastic material.

[0084] The upper end 721 of the connecting track 72 is placed on the outlet end 83 of the guide transfer member 712 and bolted to the bottom of the connecting track 72 through the fixing hole 833a. Simultaneously, the two sides of the upper end 721 abut against two outlet limiting plates 834, and the connecting positioning groove 504 engages with the positioning protrusion 832. In this way, the upper end 721 can be securely connected to the guide transfer member 712.

[0085] Furthermore, the shapes of the two lining strips 52a and 52b are the same as the shapes of the guide protrusions 811 formed on both sides of the top of the first main guide section 81, and when the connecting track 72 is connected to the guide transfer member 712, the two lining strips 52a and 52b are aligned with the two guide protrusions 811 respectively, forming a continuous strip-shaped support structure.

[0086] like Figures 3 to 5As shown, the off-track component 71 is positioned higher than the turning guide connecting member 73. The connecting track 72 connects the off-track component 71 and the turning guide connecting member 73. The portion of the connecting track 72 near the bearing track 63 is a straight section, and the portion of the bearing track 63 near the connecting track 72 is also a straight section. Since both the connecting track 72 and the bearing track 63 support the hanger 200, and the hanger 200 moves in different directions on both, the connecting track 72, the bearing track 63, and the connection between them form a turning path for the hanger 200. The turning guide connecting member 73, acting as a guide connecting member, is positioned at the bend between the connecting track 72 and the bearing track 63.

[0087] Figure 9 This is an embodiment of the present invention. Figure 5 Enlarged view of section D of the middle frame; Figure 10 This is a schematic diagram of the structure of the turning guide connecting member in an embodiment of the present invention.

[0088] like Figure 9 and Figure 10 As shown, the turning guide connecting member 73 includes a second main guide section 91 and two connecting ends 92. In this embodiment, the second main guide section 91 and the two connecting ends 91 are integrally formed, and their material is a mixture of polyamide 66 and glass fiber.

[0089] The second main guide section 91 is curved in the length direction. The second main guide section 91 has an upper part 911 and a lower part 912.

[0090] The upper part 911 has a trapezoidal cross-section that matches the shape of the hook on the clothes hanger 200. Protrusions 911a and 911b are formed on both sides of the top of the upper part 911, extending along the length of the second main guide section 91, and both have arc-shaped top surfaces. The lower part 912 is located below the upper part 911 and has a roughly rectangular cross-section.

[0091] The two connecting ends 92 are used to connect the next-level end 722 of the connecting track 72 and the first end 63a of the carrying track 63, respectively. For ease of description, the connecting end 92 that connects to the next-level end 722 will be referred to as the upstream connecting end 92A, and the connecting end 92 that connects to the first end 63a will be referred to as the downstream connecting end 92B.

[0092] The upstream connecting end 92A has a turning support plate 921A, a turning positioning protrusion 922A, and two turning limiting plates 923A. The turning support plate 921A is located on the lower part 912 and extends outward from the lower edge of the lower part 912, and has a turning mounting hole 924a on it; the turning positioning protrusion 922A is located on the upper part 911 and extends outward from the middle edge of the upper part 911.

[0093] The downstream connection end 92B has a corner support plate 921B, a corner positioning protrusion 922B, and two corner limiting plates 923B. The corner support plate 921B is located on the lower part 912 and extends outward from the lower edge of the lower part 912, and has a corner mounting hole 924b on it; the corner positioning protrusion 922B is located on the upper part 911 and extends outward from the middle edge of the upper part 911.

[0094] The track structure of the supporting track 63 is the same as that of the connecting track 72, the only difference being the arrangement of the tracks. Therefore, the supporting track 63 also has two top bushings 108a and 108b, as well as a positioning groove between the bushings 108a and 108b, which is referred to as the supporting positioning groove 108c.

[0095] The next-stage end 722 of the connecting track 72 is placed on the bend support plate 921A of the upstream connecting end 92A of the bend guide connecting member 73 and is bolted to the bottom of the connecting track 72 through the bend mounting hole 924a. At the same time, the two sides of the next-stage end 722 also abut against two bend limiting plates 923A, and the connecting positioning groove 504 is engaged with the bend positioning protrusion 922A.

[0096] The first end 63a of the bearing track 63 is placed on the bend support plate 921B of the downstream connecting end 92B of the bend guide connecting member 73, and its bottom is bolted to the bend mounting hole 924b of the bend guide connecting member 73. At the same time, the two sides of the first end 63a also abut against the two bend limiting plates 923B, and the bearing positioning groove 108c is engaged with the bend positioning protrusion 922B.

[0097] Furthermore, the two bushings 108a and 108b of the supporting track 63 have the same shape as the protrusions 911a and 911b of the second main guide section 91 and the two bushings 52a and 52b of the connecting track 72. When the supporting track 63 and the connecting track 72 are connected to the turning guide connecting member 73, the two bushings 108a and 108b are aligned with the two guide protrusions 811 respectively, and the two guide protrusions 811 are also aligned with the two bushings 52a and 52b respectively, thereby forming a continuous strip-shaped support structure.

[0098] like Figures 3 to 5As shown, the second connecting track segment 65 is divided into a next-level upstream track segment 651a and a next-level downstream track segment 651b along the conveying direction D4, based on the position of the turning guide connecting member 73. Correspondingly, the load-bearing track 63 corresponding to the first connecting track segment 213 is divided into an upstream load-bearing track segment 632a and a downstream load-bearing track segment 632b, wherein the upstream load-bearing track segment 632a corresponds to the next-level upstream track segment 651a, and the downstream load-bearing track segment 632b corresponds to the next-level downstream track segment 651b. The bottom end of the upstream load-bearing track segment 632a is the second end 63b, and the top end of the downstream load-bearing track segment 632b is the first end 63a, with the second end 63b located above the first end 63a.

[0099] As described above, since the upstream track section 213a is positioned higher than the off-track assembly 71, and the off-track assembly 71 is positioned higher than the turning guide connecting member 73, and the connecting track 72 is inclinedly connected to the off-track assembly 71 and the turning guide connecting member 73, and the turning guide connecting member 73 is positioned higher than the downstream bearing track section 632b, the hanger 200, after being led out by the off-track assembly 71, can still slide down along the connecting track 72 by gravity and be guided by the turning guide connecting member 73, entering the downstream bearing track section 632b of the first next-level conveying track 23a. This achieves the transfer of the hanger 200 from the first upper-level conveying track 21a to the first lower-level conveying track 23a, a process that relies solely on gravity and requires no additional driving force. When the hanger 200 is on the downstream bearing track section 632b, its hook-in opening 201a faces outwards from the first lower-level conveying track 23a.

[0100] The birdhook-type conveyor unit 61 is used to move the clothes hanger 200 on the support track 63. The guide rail 62 is arranged in a ring and is used to guide the movement direction of the birdhook-type conveyor unit 61. In this embodiment, multiple birdhook-type conveyor units 61 are continuously distributed on the guide rail 62, and the two together form a birdhook-type closed-loop installation track.

[0101] Therefore, the first-level conveyor track 23a can transport the clothes hanger 200 in the following direction: Figure 3 The direction indicated by the middle arrow D4. In the following description, front and back directions refer to the front and back directions on the conveying direction D4, left and right directions refer to the left and right directions when facing the conveying direction D4 (i.e., facing the direction indicated by D4), and up and down directions refer to the up and down directions during actual installation.

[0102] Figure 11 This is a schematic diagram of the structure of multiple bird hook conveying units connected together in an embodiment of the present invention; Figure 12This is an exploded view of the structure of the bird hook conveyor unit in an embodiment of the present invention;

[0103] like Figure 11 and Figure 12 As shown, the bird hook type conveying unit 61 includes a bird hook 11, a bird hook seat 12, a reset member 13, a connecting member 14, and a moving member 15.

[0104] The bird hook 11 has a bird hook body 111, a pull groove 111a provided at the rear of the bird hook body 111, and a shaft hole 112, a limiting hole 113, and a receiving hole 114 provided at the front of the bird hook body 111.

[0105] The length of the bird hook 111 is basically consistent with the conveying direction D1, and its length is 140mm. In addition, the lower front edge of the bird hook body 111 is a sloping edge that gradually slopes backward from top to bottom.

[0106] The pull groove 111a is used to hook the hook of the clothes hanger 200, and its shape is adapted to the hook.

[0107] The shaft hole 112 is a circular hole that penetrates the bird hook body 111 in the left-right direction, located closer to the end edge of the bird hook 11 than the limiting hole 113. The limiting hole 113 is an elliptical hole that penetrates the bird hook body 111 in the left-right direction, with the major axis of its ellipse roughly aligned with the vertical direction. The receiving hole 114 extends inward from the top surface of the bird hook body 111, with its extension direction aligned with the major axis of the limiting hole 113.

[0108] The bird hook holder 12 in this embodiment is used to install the bird hook 11, and has a strip-shaped seat body 121, a mounting part and two connecting ends 122.

[0109] The base 121 is strip-shaped, with its length consistent with the front-to-back direction, and a specific length of 200mm. The mounting part includes two mounting plates 123 extending downward from both sides of the bottom of the base 121. Each mounting plate 123 is provided with four mounting holes 124, and the mounting holes 124 on both mounting plates 123 are arranged opposite each other, that is, a total of four pairs of mounting holes 124 are provided on the two mounting plates 123.

[0110] The bird hook 11 is installed through two pairs of mounting holes 124 at the front. Specifically, when the bird hook 11 is installed with the bird hook seat 12, the shaft hole 112 is hinged to the more forward pair of the two pairs of mounting holes 124 via a pivot 125, allowing the body 111 to rotate around the shaft hole 112. Simultaneously, two limiting posts (not shown in the figure) are fixedly installed on the more rearward pair of the two pairs of mounting holes 124, with the ends of the limiting posts extending inward into the limiting holes 113, thereby restricting the degree of rotation of the bird hook body 111. That is, the rotatable range of the bird hook 11 is limited to the positions corresponding to both ends of the long axis of the limiting holes 113.

[0111] The reset member 13 is a spring, one end of which is fixed to the bottom surface of the base 121 between the two mounting plates 123, and the other end abuts against the bottom of the receiving hole 114. The reset member 13 provides a downward force to the bird hook body 11 through its spring force, so that when the bird hook 11 is not subjected to external force, it abuts against the bearing rail 63 located below it due to the spring force of the reset member 13.

[0112] When the hanger 200 enters the support track 63 from the connecting track 105, once the bird hook 11 moves forward from the rear side of the hanger 200, the hook of the hanger 200 will abut against the lower front edge of the bird hook body 111. Since the lower front edge of the bird hook body 111 is a sloping edge that gradually slopes backward from top to bottom, the bird hook body 111 will not drive the hanger 200 forward, but will tilt upward around the shaft hole 112 (i.e., the end where the pull groove 111a is located tilts upward). The bird hook 11 continues to move forward, and when the pull groove 111a reaches the hanger 200 and there are no other hangers 200 on the support track 63 below the bird hook body 111, the spring force of the reset member 13 causes the bird hook 11 to rotate downward, so that the hook of the hanger 200 is hooked by the pull groove 111a, and thus can be pulled forward by the bird hook 11. In addition, since the size of the pull groove 111a matches the hook of the hanger 200, it can only hook one hanger 200 at a time and pull it forward. The hangers 200 that are not pulled away will remain in place and be pulled away by the next hook 11.

[0113] Two connecting ends 122 are located at the front and rear ends of the base 121, respectively, and are used to connect two bird hook seats 12 that are adjacent to the bird hook seat 12 in the conveying direction. The connecting end 122 located at the front end of the base 121 is referred to as the front connecting end 122A, and the connecting end 122 located at the rear end of the base 121 is referred to as the rear connecting end 122B.

[0114] The front connecting end 122A has two front connecting plates 1221A, which are arranged side by side in the vertical direction, and both are provided with a front connecting hole 1222A that runs through in the vertical direction.

[0115] The rear connection end 122B has two rear connection plates 1221B, which are arranged side by side in the left and right direction, and both are provided with a rear connection hole 1222B that runs through in the left and right direction.

[0116] When multiple bird hook conveying units 61 are connected in sequence, the bird hook seats 12 in two adjacent bird hook conveying units 61 are connected by a connecting member 14. At the same time, a moving component 15 is also provided at the connecting member 62.

[0117] The connecting member 14 is provided at the front connecting end 122A, and includes a front connecting plate 141 and a rear connecting plate 142. The front connecting plate 141 is provided with a front connecting hole 143, and the rear connecting plate 142 is provided with a rear connecting hole 144. The center lines of the front connecting hole 143 and the rear connecting hole 144 are perpendicular to each other.

[0118] The movable component 15 is located at the front connecting end 12A of the bird hook seat 12, and includes a roller frame 151 and a roller assembly mounted on the roller frame 151. The roller frame 151 has a downwardly extending central through shaft 152 at its bottom end, and the bottom end of the central through shaft 152 has an external thread.

[0119] When two adjacent bird hook conveying units 61 are connected, the front connecting end 122A of the latter bird hook conveying unit 61 is connected to the rear connecting end 122B of the former bird hook conveying unit 61 via the connecting member 14 and the central through shaft 152.

[0120] Specifically, the rear connecting plate 142 extends between the two rear connecting plates 1221B of the preceding bird hook seat 12. A bolt or other connecting component passes through the rear connecting hole 144 and the rear connecting hole 1222B, and is fixedly connected to a nut, thus achieving a rotatable connection between the rear connecting plate 142 and the rear connecting end 122B. Simultaneously, the front connecting plate 141 extends between the two front connecting plates 1221A of the following bird hook seat 12. The central through shaft 152 passes sequentially through the upper front connecting hole 1222A, the front connecting hole 143, and the lower front connecting hole 1222B, and is threadedly connected to a nut, thereby achieving a rotatable connection between the front connecting plate 141 and the front connecting end 122A.

[0121] Since the front connecting holes 1222A all penetrate the front connecting plate 1221A in the vertical direction, the front connecting plate 141 and the front connecting end 122A are rotatably connected via the central through shaft 152, allowing adjacent bird hook seats 12 to rotate left and right. Since the rear connecting holes 1222B all penetrate the rear connecting plate 1221B in the horizontal direction, the rear connecting plate 142 and the rear connecting end 122B are rotatably connected, allowing adjacent bird hook seats 12 to rotate up and down. Therefore, adjacent bird hook seats 12 can rotate both left and right and up and down simultaneously, meaning their relative rotation has two degrees of freedom.

[0122] Figure 13 This is a schematic diagram of the structure of the second drive unit when the moving component and the guide rail are in the engagement state in an embodiment of the present invention.

[0123] like Figure 13As shown, the function of the movable component 15 is to move the bird hook seat 12. The roller assembly therein includes a load-bearing roller 153, a movable wheel axle 154, a guide roller 155, and a guide wheel mounting part 156.

[0124] The movable axle 154 is located on the top of the roller frame 151 and extends in the left-right direction. There are two load-bearing rollers 153, which are installed on both sides of the movable axle 154, and their central axes are both in the left-right direction.

[0125] There are two guide wheel mounting parts 156, which are located in the middle of the roller frame 151 and arranged in the front-to-back direction. There are also two guide rollers 155, which are mounted on the guide wheel mounting parts 156 respectively, and the axes of both are in the vertical direction.

[0126] The lower part of the guide rail 62 has an opening, and there are two inwardly extending bearing flanges 621 on both sides of the opening. The two bearing flanges 621 are distributed on the guide rail 62 in the front-back direction, and two load-bearing rollers 153 are respectively located on the two bearing flanges 621 and can slide on the bearing flanges 621 in the front-back direction.

[0127] The inner sides of the two bearing flanges 621 are also provided with downwardly extending guide flanges 622. The guide roller 155 is located between the two guide flanges 622 and can contact the guide flanges 622, so that the moving member 15 is not prone to deviation when it moves.

[0128] The first next-level conveying track 23a in this embodiment is also provided with a second driving unit 64 for driving the movement of each bird hook conveying unit 61. The second driving unit 64 includes a drive motor 641, a first driving wheel 642 and a second driving wheel 643.

[0129] The drive motor 641 is fixedly mounted near the guide rail 62. Figure 13 (In order to clearly show the structure, the mounting bracket and other structures have been omitted).

[0130] The first drive wheel 642 and the second drive wheel 643 are respectively mounted on both sides of the guide rail 62, and their central axes are both vertical. Simultaneously, the surfaces of the first drive wheel 642 and the second drive wheel 643 abut against the two side surfaces of the bird hook seat 12, thus "clamping" the bird hook seat 12 between the two sides. The first drive wheel 642 is connected to the output shaft of the drive motor 641 through a transmission mechanism, and can rotate under the drive of the drive motor 641. When the first drive wheel 642 rotates, it drives the bird hook seat 12 in contact with it to move through friction. The next bird hook seat 12 continues to abut against the first drive wheel 642, thus continuing to be driven by the first drive wheel 642. During the movement, the second drive wheel 643 abuts against the bird hook seat 12 from the opposite side of the first drive wheel 642, and is driven to rotate together by the friction of the bird hook seat 12, thus stabilizing the bird hook seat 12.

[0131] In this embodiment, since the moving member 15 is connected to the connecting member 14 via the central through shaft 152, and the connecting member 14 connects two adjacent bird hook seats 12, when each load-bearing roller 153 moves forward under the drive of the second drive unit 64, it drives each bird hook seat 12 to move forward, causing the bird hook 11 to move forward, thereby hooking the clothes hanger 200 and pulling it forward. Furthermore, the structure of the first drive unit is the same as the structure of the second drive unit 64.

[0132] Figure 14 This is a schematic diagram of the connection structure of the first conveying and transfer device, the first sorting and storage device, and the second conveying and transfer device in an embodiment of the present invention.

[0133] like Figure 14 As shown, the first sorting and storage device 103a is disposed between the first conveying and transfer device 102a and the second conveying and transfer device 102b, and is connected to both the first conveying and transfer device 102a and the second conveying and transfer device 102b. The second conveying and transfer device 102b has a second upper-level conveying track 21b, a second connecting part 24b, and a second lower-level conveying track 23b. The second upper-level conveying track 21b has the same structure as the first upper-level conveying track 21a, the second connecting part 24b has the same structure as the first connecting part 24a, and the second lower-level conveying track 23b has the same structure as the first lower-level conveying track 23a, which will not be described in detail here.

[0134] Figure 15 This is a schematic diagram of the connection structure between the first conveying and transferring device and the first sorting and storage device in an embodiment of the present invention;

[0135] Figure 16 yes Figure 15 Enlarged view of section E of the middle frame; Figure 17 yes Figure 14 Enlarged view of section F of the middle frame; Figure 18 yes Figure 14 Enlarged view of the middle frame G section.

[0136] like Figures 15 to 18 As shown, multiple notches 631 are provided on the carrying track 63 of the first downstream conveying track 23a. The multiple notches 631 are evenly distributed along the conveying direction D4'. The carrying track 63 has a notch front end 6311 and a notch rear end 6312 corresponding to each notch 631, wherein the notch front end 6311 is located in front of the notch 631, and the notch rear end 6312 is located behind the notch 631.

[0137] The first sorting and storage device 103a includes a storage line 25, a diversion component 26, a guide component 27, and a blocking component 28.

[0138] The number of storage lines 25 is the same as the number of diversion components 26 and the number of notches 631, and the three are arranged in a one-to-one correspondence. Multiple storage lines 25 are arranged approximately parallel to each other. Each storage line 25 has a strip guide rail and is constructed as another type of bird-hook-shaped conveyor track, referred to as the second bird-hook-shaped conveyor track. The second bird-hook-shaped conveyor track is a prior art bird-hook-shaped conveyor track, including a second bird-hook 251 and a hanger rail 252 disposed below the second bird-hook 251 for supporting the hanger 200. The working principle of the second bird-hook 251 is the same as that of the bird-hook 11, and the second bird-hook-shaped conveyor track also has a bird-hook drive unit (not shown in the figure), which is a prior art motor-driven, chain-driven structure. The structure of the hanger rail 252 is the same as that of the connecting rail 72, disposed on one side of the strip guide rail, and has an upstream storage end 2521 and a downstream storage end 2522.

[0139] Diverting component 26 is located at the corresponding notch 631 and includes connecting track section 341, telescopic track section 342 and telescopic drive component (not shown in the figure).

[0140] The connecting track segment 341 is disposed on the front end 6311 of the notch of the carrying track 63 and is connected to the upstream storage end 2521 of the corresponding storage line 25. The telescopic track segment 342 is disposed on the rear end 6312 of the notch of the carrying track 63 and can extend a section of track under the drive of the telescopic drive member. The extended section of track fits against the connecting track segment 341, thereby closing the corresponding notch 631. At this time, along the conveying direction D4' ( Figure 16As the hanger 200, conveyed in the direction indicated by arrow D4', passes the diversion assembly 26, it continues to move forward along the conveying direction D4 without entering the corresponding storage line 25. Furthermore, the telescopic track section 342 can retract its extended section under the drive of the telescopic drive, thus opening the corresponding notch 631. At this time, the hanger 200, conveyed along the conveying direction D4', passes the diversion assembly 26 and directly enters the corresponding storage line 25 through the notch 631, continuing along the conveying direction D5 (…). Figure 16 The material is transported in the direction indicated by arrow D5 in the diagram. Following this method, the purpose of classified storage (sorting storage) can be achieved through the first next-level conveyor track 23a, multiple diversion components 26, and multiple storage lines 25.

[0141] The hanger 200 is also equipped with an identification code corresponding to the garment it carries. This identification code is used to identify the information of the garment, thereby facilitating its classification and storage. Multiple barcode readers (not shown in the figure) are also installed on the carrying rail 63 of the first downstream conveyor rail 23a. These barcode readers are configured one-to-one with multiple diversion components 26 and are positioned upstream of the notch front end 6311 of the corresponding notch 631. They are used to read the codes of passing hangers 200, thereby instructing the corresponding diversion component 26 to switch between a closed and open state, allowing the hanger 200 to enter the corresponding storage line 25.

[0142] like Figure 14 and Figure 17 As shown, the guide assembly 27 includes a storage guide connecting member 271 and a storage connecting rail 272. The storage guide connecting member 271 has the same structure as the turning guide connecting member 73, and the storage connecting rail 272 has the same structure as the hanger rail 252. One end of the storage guide connecting member 271 is connected to the downstream storage end 2522 of the hanger rail 252, and the other end is connected to one end of the storage connecting rail 272. The other end of the connecting rail 272 is pointed, and its pointed edge is positioned above the "G"-shaped format member 212' of the second upper-level conveying rail 21b, for guiding the hanger 200 onto the format member 212'. Furthermore, the hanger rail 252 is positioned higher than the format member 212', and the entire guide assembly 27 is tilted vertically, allowing the hanger 200 to slide freely along the guide assembly 27 onto the second upper-level conveying rail 21b under its own weight.

[0143] like Figure 14 and Figure 18As shown, the number of blocking components 28 is the same as the number of storage lines 25, and multiple blocking components 28 are arranged one-to-one on multiple storage lines 25. Specifically, the blocking components 28 are arranged on the storage line 25 near the downstream storage end 2522. The blocking component 28 has a motor-driven lever 281. When the lever 281 is in the position... Figure 17 When the blocking position is shown, the stop bar 281 is placed horizontally on the hanger rail 252. When the second hook 251 hooks the hanger 200 and passes the stop bar 281, the front part of the second hook 251 is blocked by the stop bar 281 and lifted upward. The hanger 200 is no longer dragged by the rear part of the second hook 251 and remains on the hanger rail 252. When the stop bar 281 leaves the above blocking position, the hanger 200 can smoothly enter the second upper-level conveyor rail 21b via the guide assembly 27.

[0144] The first transfer and return mechanism 104a includes a transfer and return track 106, a return diversion component 1041, a return guide component 1042, and a first return movement drive mechanism (not shown in the figure).

[0145] The transfer return track 106 is disposed between the second lower-level conveyor track 23b and the first upper-level conveyor track 21a, and is used to return the hangers 200 on the second lower-level conveyor track 23b to the first upper-level conveyor track 21a. The structure of the transfer return track 106 is the same as that of the storage line 25, that is, it is a chain-driven second bird-hook type conveyor track. The hanger rail transfer return track 106 has a first downstream return end 1061 and a first upstream return end 1062. The first downstream return end 1061 is close to the second lower-level conveyor track 23b, and the first upstream return end 1062 is close to the first upper-level conveyor track 21a.

[0146] A return diversion assembly 1041 is disposed on the first downstream return end 1061. The first downstream return end 1061 is connected to the second next-stage conveyor track 23b via the return diversion assembly 1041. The structure of the return diversion assembly 1041 is the same as that of the diversion assembly 26. In addition, the second next-stage conveyor track 23b is provided with a notch corresponding to the return diversion assembly 1041 and a barcode reader. The structure of the notch is the same as that of the notch 631, and the return diversion assembly 1041 is disposed at the notch. The barcode reader is disposed upstream of the notch and close to the notch, and is used to read the code of the passing hanger 200, thereby instructing the return diversion assembly 1041 whether to allow the hanger 200 to enter the transfer return track 106.

[0147] A return guide assembly 1042 is disposed on the first upstream return end 1062. The structure of the return guide assembly 1042 is the same as that of the guide assembly 27. The first upstream return end 1062 is connected to the first upstream conveyor track 21a through the return guide assembly 1042, thereby guiding the clothes hanger 200 on the transfer return track 106 to be smoothly transferred from the transfer return track 106 to the first upstream conveyor track 21a by its own gravity.

[0148] In this embodiment, the part of the second lower-level conveying track 23b that connects to the first downstream return end 1061 is located downstream of the part where the diversion component is installed, and the part of the first upper-level conveying track 21a that connects to the first upstream return end 1062 is located upstream of the part where the off-track component 71 is connected.

[0149] The first return movement drive mechanism is mounted on the transfer return track 106, and is used to drive the chain on the transfer return track 106 to rotate, thereby causing the second bird hook to hook the clothes hanger 200 and move it back along the transfer return track 106. The structure of the first return movement drive mechanism is the same as that of the bird hook drive unit, and both are existing technologies, so they will not be described in detail here.

[0150] The third conveying and transfer device 102c has the same structure as the first conveying and transfer device 102a, and includes a third upper-level conveying track 21c, a third connecting part 24c, and a third lower-level conveying track 23c. The third upper-level conveying track 21c has the same structure as the first upper-level conveying track 21a, the third connecting part 24c has the same structure as the first connecting part 24a, and the third lower-level conveying track 23c has the same structure as the first lower-level conveying track 23a; these details will not be elaborated further here.

[0151] The third upper-level conveyor track 21c is connected to the second lower-level conveyor track 23b via the second sorting and storage device 103b. The connection method between the second sorting and storage device 103b and the third upper-level conveyor track 21c is the same as the connection method between the first sorting and storage device 103a and the second upper-level conveyor track 21b, and the connection method between the second sorting and storage device 103b and the second lower-level conveyor track 23b is the same as the connection method between the first sorting and storage device 103a and the first lower-level conveyor track 23a. The structure of the second sorting and storage device 103b can be exactly the same as the structure of the first sorting and storage device 103a, or it can have some differences from the structure of the first sorting and storage device 103a, for example, the number of storage lines 25 is different.

[0152] The second transfer and return mechanism 104b is disposed between the third lower-level conveyor track 23c and the second upper-level conveyor track 21b, and is used to return the hangers 200 on the third lower-level conveyor track 23c to the second upper-level conveyor track 21b. The third transfer and return mechanism 104c is disposed between the third lower-level conveyor track 23c and the first upper-level conveyor track 21a, and is used to return the hangers 200 on the third lower-level conveyor track 23c to the first upper-level conveyor track 21a. The structures of the second transfer and return mechanism 104b and the third transfer and return mechanism 104c are the same as those of the first transfer and return mechanism 104a.

[0153] In this embodiment, the portions of the third lower-level conveying track 23c that connect to both the second transfer and return mechanism 104b and the third transfer and return mechanism 104c are located downstream of the portion connecting the third lower-level conveying track 23c and the third connecting part 24c, and the portion connecting the third lower-level conveying track 23c to the third transfer and return mechanism 104c is located further downstream of the latter two. The portion of the first upper-level conveying track 21a that connects to the third transfer and return mechanism 104c is located downstream of the portion connecting the first upper-level conveying track 21a and the first connecting part 24a. The portion of the second upper-level conveying track 21b that connects to the second transfer and return mechanism 104b is located downstream of the portion connecting the second upper-level conveying track 21b and the second connecting part 24b.

[0154] The outbound device 105 includes at least one outbound line 30. The structure of the outbound line 30 is similar to that of the storage line 25, and the outbound line 31 is also connected to the third downstream conveyor track 23c via the same structure as the diversion assembly 26. The outbound line 31 is used to output the hangers 200 from the third downstream conveyor track 23c. In this embodiment, there are three outbound lines 31, which achieve the purpose of sorting and outputting the garments.

[0155] The working principle of the rackless warehouse sorting system 100 is as follows:

[0156] Multiple garment hangers 200 are sequentially stored using the storage device 101.

[0157] These hangers 200 are then conveyed to the first conveying and transfer device 102a, and then enter the corresponding storage lines 25 of the first sorting and storage device 103a through multiple diversion components 26 set on the first next-level conveying track 23a.

[0158] When it is necessary to store the hanger 200 on the first sorting storage device 103a, the stop bar 281 of the blocking assembly 28 on the storage line 25 is in the blocking position, thereby keeping the hanger 200 on the storage line 25.

[0159] When the hanger 200 does not need to be stored on the first sorting and storage device 103a, the stop bar 281 of the blocking component 28 leaves the blocking position, so that the hanger 200 on the storage line 25 can be smoothly transported to the second conveying and transfer device 102b, and then enter the corresponding storage line 25 of the second sorting and storage device 103b through multiple diversion components 26 set on the second next-level conveying track 23b respectively.

[0160] The process of sorting and storing hangers 200 on the second sorting and storage device 103b and the process of sorting and storing hangers 200 on the first sorting and storage device 103a are the same.

[0161] When the hanger 200 in the second sorting and storage device 103b enters the outbound device 105 through the third conveying and transfer device 102, it enters the corresponding outbound line 30 for sorting and output (categorized outbound) through multiple diversion components set on the third next-level conveying track 23c.

[0162] During the above process, there may be a situation where the hanger 200 enters the wrong storage line 25 when it enters the first sorting and storage device 103a. In this case, the hanger 200 can be returned to the first conveying and transfer device 102a by the first transfer return mechanism 104a set on the second conveying and transfer device 102b, so as to re-enter the first sorting and storage device 103a.

[0163] Furthermore, during the above process, there may be a situation where the hanger 200 enters the wrong storage line 25 when it enters the second sorting and storage device 103a. In this case, the hanger 200 can be returned to the second conveying and storage device 102b via the second transfer return mechanism 104b provided on the third conveying and transfer device 102c, thereby re-entering the second sorting and storage device 103b. Alternatively, the hanger 200 can be returned to the first conveying and transfer device 102a via the third transfer return mechanism 104c provided on the third conveying and transfer device 102c, thereby re-transferring.

[0164] In addition, during the above process, if the hanger 200 is being transported on the next level conveying track 23 of the conveying transfer device 102 without leaving the next level conveying track 23 through any gap 631, and instead continues to move on the next level conveying track 23, the hanger 200 can also return to the upstream conveying transfer device 102 through the transfer return mechanism 104 set on the next level conveying track 23, and then be transported again.

[0165] The role and effect of the embodiments

[0166] According to the fixed shelf-less storage and sorting system 100 involved in this embodiment, it includes m conveying and transfer devices 102 and m-1 sorting and storage devices 103. The conveying and transfer devices 102 include an upper-level conveying track 21, a lower-level conveying track 23, and a connecting part 24. The upper-level conveying track 21 is composed of a random conveying type conveying track, so that the hangers 200 carrying clothing output from the upper-level area can randomly enter the connecting track 71 and be transferred to the lower-level conveying track. This random conveying method not only meets the actual output needs of the upper-level area, but also improves the conveying efficiency. In addition, since the lower-level conveying track 23 is composed of a single-item conveying type conveying track, the hangers 200 can be conveyed as single items after entering the lower-level conveying track 23, which facilitates the classification and storage of the hangers 200 on the sorting and storage devices 103 in the lower-level area, thereby achieving the purpose of sorting and storage.

[0167] Furthermore, since m conveying and transfer devices 102 are arranged sequentially along the conveying direction of the clothes hanger 200, and m-1 sorting and storage devices 103 are respectively arranged between two adjacent conveying and transfer devices 102, the goods carrier can be classified and stored in a first-level manner (or stored without classification) after passing through a conveying and transfer device 102 and an adjacent sorting and storage device 103 along the conveying direction. Ultimately, the system can achieve multi-level classification and storage.

[0168] Furthermore, since the system also includes at least one transfer return track 106, which is disposed between the two conveying transfer devices 102, and one end of the transfer return track 106 is connected to the upper-level conveying track 21 of one of the two conveying transfer devices 102, and the other end is connected to the lower-level conveying track 23 of the other of the two conveying transfer devices 102, the clothes hanger 200 on the downstream conveying transfer device 102 along the conveying direction can be returned to the upstream conveying transfer device 102 through the transfer return track 106, so that the clothes hanger 200 can be re-sorted and stored, thereby improving the flexibility and accuracy of the sorting and storage of the entire system.

[0169] Furthermore, the two conveying and transferring devices 102 connected to the transfer return track 106 can be either adjacent or non-adjacent. When the two conveying and transferring devices 102 are arranged adjacently, the hanger 200 located on a storage line 25 between the two conveying and transferring devices 102 can be re-stored on another storage line 25 in that area via the transfer return track 106; when the two conveying and transferring devices 102 are not arranged adjacently, the hanger 200 can be re-stored between different storage areas via the transfer return track 106.

[0170] Furthermore, since the rackless warehousing and sorting system 100 of this embodiment uses a track for transportation and storage, it does not require the construction of fixed racks or the installation of stacker cranes, shuttle cars, or other conveying equipment, making it easy to build and cost-effective.

[0171] Furthermore, because the transfer return track 106 has a first downstream return end 1061 and a first upstream return end 1062, the first downstream return end 1061 is provided with a return diversion component and is connected to the corresponding next-level conveying track 23 through the return diversion component, and the first upstream return end 1062 is provided with a return guide component and is connected to the corresponding previous-level conveying track 21 through the return guide component, the clothes hanger 200 on the next-level conveying track 23 can be smoothly transferred to the transfer return track 106, and then transferred from the transfer return track 106 to the previous-level conveying track 21.

[0172] Furthermore, since the sorting and storage device 103 includes a plurality of storage lines 25, each storage line 25 having an upstream storage end 2521 and a downstream storage end 2522, the upstream storage end 2521 is provided with a diversion component 26, which is connected to the corresponding upstream next-level conveyor track 23. The downstream storage end 2522 is provided with a guide component 27, which is connected to the corresponding downstream upper-level conveyor track 21. Therefore, the diversion component 26 can guide the hangers 200 on the corresponding upstream next-level conveyor track 23 to different storage lines 25 for sorting and storage, and the guide component 27 can smoothly guide the hangers 200 stored on the storage line 25 to the corresponding downstream upper-level conveyor track 21. Furthermore, since a blocking component 28 is also provided near the downstream storage end 2522 of the storage line 25, the blocking component 28 can control whether the hangers 200 on the storage line 25 enter the corresponding upper-level conveyor track 21.

[0173] Furthermore, a first return movement drive mechanism is also provided on the transfer return track 106, which can drive the clothes hanger 200 to return on the transfer return track 106.

[0174] Furthermore, because the upper-level conveyor track 21 is composed of a grid-type conveyor track, it can effectively achieve the purpose of random conveying; because the lower-level conveyor track 23 is composed of a hook-type conveyor track, it can effectively achieve the purpose of single-item conveying. Since the conveying directions of the upper-level conveyor track 21 and the lower-level conveyor track 23 are opposite, the hook-in opening 201a of the hook 201 on the upper-level conveyor track 21 faces inwards from the ring of the upper-level conveyor track 21, and the hook-in opening 201a of the hook 201 on the lower-level conveyor track 23 faces outwards from the ring of the lower-level conveyor track 23, so the clothes hanger 200 can be smoothly transferred from the upper-level conveyor track 21 to the lower-level conveyor track 23 for conveying.

[0175] Furthermore, since the next-level conveying track 23 has a carrying track 63 for carrying the hanger 200, and the connecting track 72 has an upper end 721 and a lower end 722, the upper end 721 is connected to the corresponding upper-level conveying track 21 through the off-track component 71, and the lower end 722 is connected to the carrying track 63 through the turning guide connecting member 73, the hanger 200 on the upper-level conveying track 21 can be easily transferred to the carrying track 63 of the next-level conveying track 23 through the off-track component 71, the connecting track 72, and the turning guide connecting member 73.

[0176] Furthermore, since the upper-level conveying track 21 has an upper-level upstream track segment 213a that is upstream of the corresponding derailment component 71 along the conveying direction D1 of the hanger 200 and an upper-level downstream track segment 213b that is downstream, and the upper-level upstream track segment 213a is higher than the upper-level downstream track segment 213b, the hanger 200 conveyed along the conveying direction D1 to the upper-level upstream track segment 213a can be guided by the derailment component 71 by its own gravity and thus leave the upper-level upstream track segment 213a.

[0177] Furthermore, because the next-level conveying track 23 has an upstream track segment 651a and a downstream track segment 651b that are upstream of the hanger 200 along the conveying direction D4 compared to the turning guide connecting member 73, and the upstream track segment 651a is higher than the downstream track segment 651b, and the off-track component 71 is higher than the turning guide connecting member 73, the hanger 200 guided by the off-track component 71 can still slide down along the connecting track 72 by gravity alone and, after being guided by the turning guide connecting member 73, enter the downstream track segment 651b of the first next-level conveying track 23a. This achieves the transfer of the hanger 200 from the first upper-level conveying track 21a to the first lower-level conveying track 23a. This transfer process relies solely on gravity and does not require additional driving force.

[0178] The above embodiments are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.

[0179] For example, in this embodiment, m = 3. In actual use, the value of m can also be 2 or other integers greater than 3.

[0180] Furthermore, in this embodiment, a transfer return mechanism 104 is provided between any two of the three transfer devices 102. In actual use, only one or two transfer return mechanisms 104 need to be provided as needed.

[0181] Furthermore, in this embodiment, the third transfer return mechanism 104c is a transfer return mechanism set at intervals of one transfer device 102 (second transfer device 102b). In actual use, when there are many transfer devices, a transfer return track can be set at intervals of 2 to 4 transfer devices as needed.

[0182] In addition, in this embodiment, although the carrying track 63 is set as a non-closed loop, its first end 63a and second end 63b are both located at the lower part of the second connecting track segment 65. The second end 63b is located above the first end 63a, and there is a small gap between them, so that the entire carrying track 63 is approximately looped. The part of the second end 63b near the first end 63a is pointed, which allows the hanger 200 to move smoothly from the second end 63b to the first end 63a, thereby ensuring the loop movement of the hanger 200 on the first next-level conveying track 23a. However, in actual use, the carrying track can also be set to other non-closed shapes. For example, the first end of the carrying track can be set to the same structure and position as the first end 63a in the embodiment, while the second end of the carrying track can be set at a position downstream of the last gap 631 set along the conveying direction D4' (this position is downstream of the position of the second end 63b in the embodiment). As long as it can be ensured that the hanger 200 can enter the carrying track 63 from the first end and be conveyed along the carrying track 63 to each gap 631 to enter the corresponding storage line 25, and the setting of the transfer return mechanism 104 is not affected.

[0183] Furthermore, in this embodiment, the first downstream return end 1061 is connected to the second next-level conveying track 23b through the return diversion component 1041. In actual use, the return diversion component 1041 may not be provided, so that the first downstream return end 1061 is directly connected to the carrying track 63 of the second next-level conveying track 23b. In this way, any hanger 200 that passes through this connection part will enter the transfer return track 106.
