Description

Technical Field

[0001] This invention belongs to the field of cargo warehousing, specifically relating to a warehousing equipment and a warehouse sorting system without fixed shelves. Background Technology

[0002] Currently, the typical warehousing system used in the cargo storage field involves placing goods in containers, and then categorizing the containers and placing them on different fixed racks. To save space, these fixed racks are often multi-tiered in height, requiring stacker cranes, shuttle cars, and other conveying equipment for container storage, retrieval, and transfer. In this type of warehousing system, fixed racks are cumbersome to set up, occupy a large area, require significant manpower for container categorization and handling, and the conveying equipment also needs corresponding operating space.

[0003] Furthermore, when such a warehousing system is applied to industries where goods are in the form of soft sheets, such as the clothing industry, multiple garments must be packaged in the same box during transportation and storage, and the garments can only be stacked together inside the box. This leads to the following problems: First, stacked garments are prone to wrinkles, affecting their appearance, and severe wrinkles require smoothing before shipment; second, after multiple garments are packaged and stored in the same box, they must be opened and inspected before sorting or shipment, wasting manpower and resources.

[0004] Therefore, rackless warehousing and sorting systems that eliminate the need for fixed shelving, prevent garment stacking, and enable automated sorting (classification) have become a pressing need in the apparel warehousing industry. Furthermore, such rackless systems require garment classification and storage, making the design of the corresponding storage equipment particularly crucial. Additionally, classification errors are inevitable during garment classification and storage; these issues must be corrected promptly to ensure the overall classification effectiveness of the system.

The entry ring track is composed of a single-piece conveying type for sequentially conveying cargo carriers carrying goods to the multiple storage lines. The output ring track is composed of a random conveying type for randomly outputting cargo carriers from the storage lines. The conveying directions of the entry ring track and the output ring track are opposite. The return track is located between the entry ring track and the output ring track for returning cargo carriers on the output ring track to the entry ring track.

[0007] The storage equipment provided by the present invention may also have the following features: the return track has a downstream return end and an upstream return end, the downstream return end is provided with a derailment component and is connected to the output ring track through the derailment component, and the upstream return end is provided with a guide connecting member and is connected to the entry ring track through the guide connecting member.

[0008] The storage equipment provided by the present invention may also have the following features: the entry ring track has a carrying track for carrying cargo carriers, and the storage equipment also has multiple diversion components corresponding to multiple storage lines.

[0016] The role and effect of invention

[0017] According to the warehousing equipment and the rackless warehousing and sorting system of the present invention, since the warehousing equipment includes an entry ring track composed of single-piece conveying type conveying tracks, an output ring track composed of random conveying type conveying tracks, and multiple storage lines, the cargo carriers carrying goods can be transported to multiple storage lines via the entry ring track, thereby achieving the purpose of sorting and storage (classification storage). This classification storage process can be automatically realized without human operation, and the entire equipment does not involve fixed racks at all.

[0018] Furthermore, because the conveying directions of the inbound and outbound circular tracks are opposite, and the storage equipment also includes a return track located between the inbound and outbound circular tracks, the goods carriers on the outbound circular track can return to the inbound circular track. Therefore, if sorting errors occur during the sorting and storage process on the aforementioned storage line, the goods carriers can be returned to the inbound circular track via the outbound and return tracks, and then re-enter the storage line for sorting and storage. This ensures the sorting accuracy of each storage device and improves the overall sorting and storage level of the rackless storage and sorting system. Attached Figure Description

Detailed Implementation

[0037] 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, will specifically illustrate the warehousing equipment and the rackless warehousing and sorting system of the present invention.

[0038] <Example>

[0039] 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.

[0040] like Figure 1 As shown, the rackless warehousing and sorting system 100 of this embodiment is a garment warehousing system that uses tracks to transport and store goods (clothing) on ​​carriers (clothing hangers). It includes an inbound device 101, at least one storage device 102, an outbound device 104, and multiple connecting parts 105. In this embodiment, two storage devices 102 are provided, respectively referred to as the first storage device 102a and the second storage device 102b. The first storage device 102a and the second storage device 102b are located between the inbound device 101 and the outbound device 104, and along the transport direction of the clothing hangers (…). Figure 1 (The direction indicated by the solid arrow in the image is the conveying direction) are set sequentially.

[0041] The receiving device 101 is used to receive hangers carrying clothing into the warehouse. The first storage device 102a is used to classify and store (or store) the hangers. The second storage device 102b is used to classify and store the hangers output from the first storage device 102a. The outgoing device 104 is used to outgoing (or further classify and outgoing) the hangers output from the second storage device 102b.

[0042] Among them, the area where the inbound equipment 101 is located is the next level area above the area where the first storage equipment 102a is located, the area where the first storage equipment 102a is located is the next level area above the area where the second storage equipment 102b is located, and the area where the second storage equipment 102b is located is the next level area above the area where the outbound equipment 104 is located.

[0043] In this embodiment, three connecting parts 105 are provided, respectively referred to as the first connecting part 105a, the second connecting part 105b, and the third connecting part 105c. The first connecting part 105a, the second connecting part 105b, and the third connecting part 105c are respectively disposed between the inbound device 101 and the first storage device 102a, between the first storage device 102a and the second storage device 102b, and between the second storage device 102b and the outbound device 104, for connecting the tracks of these devices so that the clothes hanger can move between different devices through the connecting parts 105.

[0044] The receiving equipment 101 includes a circular track 21 for receiving goods and at least one goods loading line 22. The goods loading line 22 serves as the goods entry line of the receiving equipment 101, used to transport hangers onto the circular track 21 for receiving goods. In this embodiment, multiple goods loading lines 22 are provided.

[0045] The first storage facility 102a includes an entry ring track 23.

[0046] Figure 2 This is a three-dimensional structural diagram of the circular track for warehousing, the first connecting part, and the circular track for entry in an embodiment of the present invention; Figure 3 yes Figure 2 Enlarged view of section A of the middle frame.

[0047] 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 4 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 garments hanging on it based on the position of hook 201. Hanger 200 also has an identification code corresponding to the garment it carries, which is used to identify the garment's information for easy classification and storage.

[0048] The storage ring track 21 is a closed ring 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 hangers 200 for carrying and conveying the clothes hangers 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 existing technology and will not be described in detail here. Figure 2-4Only 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 loading track 211 in the same manner as those shown in the figure. The storage loop track 21 is also provided with a first driving unit (not shown in the figure) for driving the formatting components 212 to move. In this embodiment, the conveying direction of the storage loop track 21 is clockwise.

[0049] In this embodiment, the opening of the "G"-shaped format component 212 faces outward from the ring of the storage ring track 21. The hook 201, which enters the storage ring track 21 via the goods shelving line 22, is hooked onto the format component 212 and moves with it. The hooking opening 201a of the hook 201 on the storage ring track 21 faces inward from the ring of the storage ring track 21.

[0050] The circular track 21 for receiving goods has a connecting track section 213 for receiving goods, which is adjacent to the first storage equipment 102a and extends downward at an incline. The angle between the connecting track section 213 and the horizontal direction is 30° to 60°; specifically, it can be selected within this angle range according to the available space for the track installation. In this embodiment, the angle between the connecting track section 213 and the horizontal direction is 30°. The conveying direction on this connecting track section 213 is... Figure 4 The direction indicated by the middle arrow D1 is hereinafter referred to as the conveying direction D1.

[0051] 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.

[0052] like Figures 3 to 5 As shown, the circular track 23 for entering the warehouse 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 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 circular track 23 for entering the warehouse is opposite to the conveying direction of the circular track 21 for storing goods, i.e., counterclockwise.

[0053] The circular track 23 for entry has a storage entry-side connecting track section 65 that is adjacent to the storage equipment 101 and extends downward at an incline. This storage entry-side connecting track section 65 is arranged parallel to the storage entry-side connecting track section 213. The conveying direction on this storage entry-side connecting track section 65 is... Figure 4The direction indicated by the middle arrow D4 is hereinafter referred to as the conveying direction D4.

[0054] 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 storage entry side connecting track segment 65. The first end 63a is connected to the first connecting part 105a, thereby allowing the hanger 200 from the storage device 101 to be received from the first connecting part 105a. 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 entry loop track 23.

[0055] The first connecting part 105a is disposed between the storage device 101 and the first storage device 102a, and is used to guide the clothes hanger 200 to slide naturally from the storage ring track 21 to the entry ring track 23 without relying on any driving structure, solely by gravity. It includes a movable off-track assembly 71, a connecting track 72, and a guiding connecting member 73.

[0056] The movable derailment assembly 71 is used to transfer the hanger 200 from the storage ring track 21 to the connecting track 72. The movable derailment assembly 71 has a prior art structure, featuring a movable swing head mounted on the connecting track 72 and a drive cylinder. The piston rod of the drive cylinder is movably connected to the swing head, and the swing head can extend towards or disengage from the storage ring track 21 under the drive of the drive cylinder. When the swing head extends towards the storage ring track 21, and the hanger 200 on the storage ring track 21 moves to the swing head, the hanger 200 can leave the storage ring track 21 under the guidance of the swing head; when disengaged from the swing head on the storage ring track 21, and the hanger 200 moves back to the swing head, the hanger 200 continues to move on the storage ring track 21.

[0057] In addition, a barcode reader is installed on the circular track 21 for receiving goods, and this barcode reader is located upstream of the part of the circular track 21 corresponding to the swing head. When the hanger 200 is conveyed to the barcode reader on the circular track 21, the barcode reader reads the identification code on the hanger 200, thereby controlling the position of the swing head based on the identified information, and thus controlling whether the hanger 200 leaves the circular track 21.

[0058] One end of the connecting track 72 is connected to the movable off-track assembly 71 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 hanger 200, guided by the swing head, can enter the connecting track 72 via the upper-level end 721 after leaving the storage ring track 21. 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 storage entry side connecting track section 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.

[0059] 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°.

[0060] Figure 6 This is a schematic diagram of the connecting track in an embodiment of the present invention.

[0061] like Figure 6 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] like Figures 3 to 5 As shown, the movable off-track assembly 71 is positioned higher than the turning guide connecting member 73. The connecting track 72 connects the movable off-track assembly 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.

[0068] Figure 7 This is an embodiment of the present invention. Figure 5 Enlarged view of section D of the middle frame; Figure 8 This is a schematic diagram of the structure of the turning guide connecting member in an embodiment of the present invention.

[0069] like Figure 7 and Figure 8 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] like Figures 3 to 5 As shown, the warehouse entry-side 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 warehouse entry-side 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.

[0080] As described above, since the upstream track section 213a is positioned higher than the movable off-track assembly 71, and the movable off-track assembly 71 is positioned higher than the turning guide connecting member 73, and the connecting track 72 is inclinedly connected to the movable 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 clothes hanger 200, after being led out by the movable off-track assembly 71, can still slide down along the connecting track 72 by gravity alone and be guided by the turning guide connecting member 73 before entering the downstream bearing track section 632b of the entry ring track 23. This achieves the transfer of the clothes hanger 200 from the storage ring track 21 to the entry ring track 23, a transfer process that relies solely on gravity and requires no additional driving force. When the clothes hanger 200 is on the downstream bearing track section 632b, its hanging opening 201a faces outwards from the ring of the entry ring track 23.

[0081] 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.

[0082] Therefore, the clothes hanger 200 can be conveyed by using the circular track 23, and the conveying direction is as follows: 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.

[0083] Figure 9 This is a schematic diagram of the structure of multiple bird hook conveying units connected together in an embodiment of the present invention; Figure 10 This is an exploded view of the structure of the bird hook conveyor unit in an embodiment of the present invention;

[0084] like Figure 9 and Figure 10 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.

[0085] 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.

[0086] 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.

[0087] The pull groove 111a is used to hook the hook of the clothes hanger 200, and its shape is adapted to the hook.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] Figure 11 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.

[0104] like Figure 11 As 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] The circular track 23 for entry in this embodiment is also provided with a second drive unit 64 for driving the movement of each bird hook conveying unit 61. The second drive unit 64 includes a drive motor 641, a first drive wheel 642 and a second drive wheel 643.

[0110] The drive motor 641 is fixedly mounted near the guide rail 62. Figure 11 (In order to clearly show the structure, the mounting bracket and other structures have been omitted).

[0111] 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.

[0112] 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.

[0113] Figure 12 This is a schematic diagram of the structure of the first storage equipment in an embodiment of the present invention; Figure 13 This is a schematic diagram of the connection structure of the circular track for warehousing, the first connecting part, and the first storage equipment in an embodiment of the present invention; Figure 14 yes Figure 13 Enlarged view of section E of the middle frame; Figure 15 This is a schematic diagram of the shunt component when the gap is closed; Figure 16 yes Figure 12 Enlarged view of section F of the middle frame; Figure 17 yes Figure 12 Enlarged view of the middle frame G section.

[0114] like Figures 12 to 17 As shown, the first storage device 102a also includes an output circular track 24, a storage line 25, a diversion component 26, a guide component 27, a blocking component 28, and a return track 29.

[0115] The structure of the output circular track 24 is the same as that of the inbound circular track 21, and it is also a standard type conveyor track, so it will not be described in detail. The storage line 25 and the return track 29 are located between the inbound circular track 23 and the output circular track 24.

[0116] like Figure 13 As shown, multiple notches 631 are provided on the carrying track 63 of the circular track 23. 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.

[0117] 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 between the inlet circular track 23 and the outlet circular track 24. Each storage line 25 has a strip guide rail and is constructed as a different type of bird-hook conveyor track, referred to as the second bird-hook conveyor track. The second bird-hook conveyor track is a prior art bird-hook conveyor track, including a second bird-hook 251 and a hanger rail 252 located 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 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 track 72, located on one side of the strip guide rail, and has an upstream storage end 2521 and a downstream storage end 2522.

[0118] 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).

[0119] The connecting track segment 341 is disposed on the notch front end 6311 of the bearing 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 notch rear end 6312 of the bearing track 63. In this embodiment, the telescopic track segment 342 is movably sleeved on the notch rear end 6312 and can move from its original position under the drive of the telescopic drive member. Figure 14 The position shown is moved forward a certain distance (extended) to fit against the connecting track segment 341, so that the corresponding gap 631 is in a closed state (as shown). Figure 15 As shown), at this time, along the conveying direction D4' ( Figure 14 As 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, driven by the telescopic drive, can retract to its original position, 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 14 The goods are transported in the direction indicated by arrow D5 in the diagram. Following this method, the purpose of classified storage (sorting storage) can be achieved by using a circular track 23, multiple diversion components 26, and multiple storage lines 25.

[0120] Multiple barcode readers (not shown in the figure) are also installed on the carrying track 63 of the circular track 23. Each barcode reader is corresponding to a different diversion component 26 and is positioned upstream of the notch 631 of the corresponding notch 631. These readers are used to read the codes of passing hangers 200, thereby instructing the corresponding diversion component 26 to switch between a closed and an open state, allowing the hangers 200 to enter the corresponding storage line 25.

[0121] like Figure 12 and Figure 16 As shown, the guide assembly 27 includes a storage guide connecting member 271 and a storage connecting track 272. The storage guide connecting member 271 has the same structure as the turning guide connecting member 73, and the storage connecting track 272 has the same structure as the hanger track 252. One end of the storage guide connecting member 271 is connected to the downstream storage end 2522 of the hanger track 252, and the other end is connected to one end of the storage connecting track 272. The other end of the connecting track 272 is pointed, and its pointed edge is positioned above the "G"-shaped format member 212' of the output annular track 24, for guiding the hanger 200 onto the format member 212'. Furthermore, the hanger track 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 output annular track 24 under its own weight.

[0122] like Figure 12 and Figure 16 As 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 stop lever 281. When the stop lever 281 is located at... Figure 15 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 output annular track 24 via the guide assembly 27.

[0123] like Figure 12 As shown, the return track 29 is used to return the clothes hanger 200 on the output circular track 24 to the input circular track 23, and has a downstream return end 291 and an upstream return end 292. The downstream return end 291 is close to the output circular track 24, and the upstream return end 292 is close to the input circular track 23.

[0124] A return derailment assembly 293 is provided on the downstream return end 291, and is connected to the output annular track 24 through the return derailment assembly 293. The return derailment assembly has the same structure as the movable derailment assembly 71. In addition, a barcode reader corresponding to the return derailment assembly 293 is provided on the output annular track 24, and the barcode reader is located upstream of the corresponding part of the output annular track 24. The barcode reader is used to read the code of the passing hanger 200, thereby instructing the return derailment assembly 293 whether to allow the hanger 200 to enter the return track 29.

[0125] The upstream return end 292 is provided with a return turning guide connecting member 294, and is connected to the entry circular track 23 through the return turning guide connecting member 294. The return turning guide connecting member has the same structure as the turning guide connecting member 73.

[0126] In this embodiment, the return track 29 is substantially parallel to the storage line 25, and the part of the output circular track 24 that connects to the downstream return end 291 is located upstream of the part of the output circular track 24 that connects to the storage line 25, and the part of the entry circular track 23 that connects to the upstream return end 292 is located upstream of the gap 631.

[0127] A return drive unit (not shown in the figure) is also provided on the return track 29. The return drive unit is used to drive the clothes hanger 200 to move back along the return track 29 (the direction of the return movement is...). Figure 12 (The direction indicated by the dashed arrow). The structure of the return drive unit 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.

[0128] The output circular track 24 is used to guide the hangers 200 on the storage line 25 out of the first storage device 102a. The output circular track 24 can also guide the hangers 200 on the storage line 25 back to the entry circular track 23 via the return track 29, so as to be re-transported to other storage lines 25 of the first storage device 102a.

[0129] like Figure 1 As shown, the structure of the second storage device 102b is basically the same as that of the first storage device 102a, the only difference being the number of storage lines 25. The first storage device 102a, being the upstream storage device 102 in the conveying direction of the hangers 200, has 50-80 storage lines 25, preferably 60. The second storage device 102b has 15-30 storage lines 25, preferably 20. The second storage device 102b is used to classify and store the hangers 200 from the first storage device 102a.

[0130] The entry ring track 23 of the second storage device 102b is connected to the output ring track 24 of the first storage device 102a via a second connecting part 105b. The structure of the second connecting part 105b is the same as that of the first connecting part 105a, and the connection method between the second connecting part 105b and the entry ring track 23 of the second storage device 102b is the same as the connection method between the first connecting part 105a and the entry ring track 23 of the first storage device 102b. The connection method between the second connecting part 105b and the output ring track 24 of the first storage device 102a is the same as the connection method between the first connecting part 105a and the storage ring track 21. The function of the second connecting part 105b is to guide the clothes hanger 200 on the output ring track 24 of the first storage device 102a to move freely onto the entry ring track 23 of the second storage device 102b under its own weight.

[0131] The outbound equipment 104 includes an outbound circular track 30 and an outbound line 31.

[0132] The outbound circular track 30 has the same structure as the inbound circular track 23, and is a hook-shaped conveyor track. The outbound circular track 30 is connected to the output circular track 24 of the second storage equipment 102b via a third connecting part 105c. The structure of the third connecting part 105c is the same as that of the inbound storage room connecting part 105b, and the connection method between the third connecting part 105c and the output circular track 23 is the same as the connection method between the first connecting part 105a and the inbound circular track 23 of the first storage equipment 102b. The connection method between the third connecting part 105c and the output circular track 24 of the second storage equipment 102b is the same as the connection method between the first connecting part 105a and the inbound circular track 21. The function of the third connecting part 105c is to guide the clothes hangers 200 on the output circular track 24 of the second storage equipment 102b to move freely onto the outbound circular track 30 under their own weight.

[0133] The structure of the outbound line 31 is similar to that of the storage line 25, and the outbound line 31 is also connected to the circular track 30 for goods outbound via the same structure as the diversion component 26. The outbound line 31 is used to output the hangers 200 from the circular track 30 for goods outbound. There is at least one outbound line 31. In this embodiment, there are three outbound lines 31, which can achieve the purpose of sorting and output.

[0134] The working principle of the rackless warehouse sorting system 100 is as follows:

[0135] Multiple garment hangers 200 are sequentially stored using the storage device 101.

[0136] These hangers 200 are then conveyed to the first connecting part 105a, and then enter the corresponding storage lines 25 of the first storage equipment 102a through multiple diversion components 26 set on the entry ring track 23.

[0137] When it is necessary to store the hanger 200 on the first storage device 102a, 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.

[0138] When the hanger 200 does not need to be stored on the first storage device 102a, 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 storage device 102b via the second connecting part 105b, and then enter the corresponding storage line 25 of the second storage device 102b through the multiple diversion components 26 set on the entry ring track 23 of the second storage device 102b respectively.

[0139] The process of sorting and storing hangers 200 in the second storage device 102b and the process of sorting and storing hangers 200 in the first storage device 102a are the same.

[0140] When the clothes hanger 200 in the second storage equipment 102b enters the outbound equipment 104 through the third connecting part 105c, it enters the corresponding outbound line 31 for sorting and output (categorized outbound) through multiple diversion components set on the outbound circular track 24.

[0141] During the above process, there may be a situation where the hanger 200 enters the wrong storage line 25 when it enters the storage equipment 102. In this case, the hanger 200 can be returned to the entry circular track 23 via the return track 29 from the output circular track 24, thereby re-entering the storage line 25.

[0142] The role and effect of the embodiments

[0143] According to the storage equipment 102 and the rackless storage and sorting system 100 involved in this embodiment, the storage equipment 102 includes an inlet circular track 23, an outlet circular track 24, and multiple storage lines 25. The inlet circular track 23 is composed of a single-item conveying type, allowing hangers 200 carrying goods to be sequentially conveyed to multiple storage lines 25, thereby achieving the purpose of sorting and storage (categorized storage). The outlet circular track 24 is composed of a random conveying type, allowing hangers 200 from the storage lines 25 to be randomly output. This random conveying method not only meets the actual output needs of the multiple storage lines 25 but also improves conveying efficiency. Therefore, the storage equipment 102 can not only achieve sorting and storage functions but also quickly transfer stored hangers 200 to the next storage equipment 102 or outbound equipment 108. This categorized storage process can be automatically implemented without human operation, and the entire equipment does not involve fixed racks.

[0144] Furthermore, because the conveying direction of the inbound circular track 23 is opposite to that of the outbound circular track 24, and the storage equipment 102 also includes a return track 29 located between the inbound circular track 23 and the outbound circular track 24, the hangers 200 on the outbound circular track 24 can return to the inbound circular track 23. Therefore, if sorting errors occur during the sorting and storage process via the aforementioned storage line, the hangers 200 can be returned to the inbound circular track 23 via the outbound circular track 24 and the return track 29, and then re-enter the storage line 25 for sorting and storage. This ensures the sorting accuracy of each storage device 102 and improves the overall sorting and storage level of the entire shelfless storage and sorting system 100.

[0145] 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.

[0146] Furthermore, because the return track 29 has a downstream return end 291 and an upstream return end 292, the downstream return end 291 is provided with a return derailment component 293, which is connected to the output ring track 24 through the return derailment component 293, and the upstream return end 292 is provided with a return turning guide connecting member 294, which is connected to the entry ring track 23 through the return track 29. Therefore, the hangers 200 on the output ring track 24 can be returned to the entry ring track 23 through the return track 29. Furthermore, because the entry ring track 23 has a carrying track 63 for carrying the hangers 200, and the storage equipment 102 also has multiple diversion components 26 corresponding one-to-one with multiple storage lines 25, the diversion components 26 are arranged on the corresponding storage lines 25 and the entry ring track 23. Therefore, the hangers 200 on the entry ring track 23 can be guided to different storage lines 25 through the multiple diversion components 26 for classified storage.

[0147] Furthermore, a return movement drive unit is also provided on the return track 29 to drive the hanger 200 to return. The return movement drive unit can drive the hanger 200 to return on the track 29. A blocking component 28 is also provided on the storage line 25, which can control whether the hanger 200 on the storage line 25 enters the output circular track 24.

[0148] Because the output ring track 24 is composed of a grid-type conveyor track, it can effectively achieve the purpose of random conveying; because the input ring track 23 is composed of a hook-type conveyor track, it can effectively achieve the purpose of single-item conveying. Because the conveying direction of the output ring track 24 is opposite to that of the input ring track 23, the hook opening 201a of the hook 201 on the output ring track 24 faces the inside of the ring of the output ring track 24, and the hook opening 201a of the hook 201 on the input ring track 23 faces the outside of the ring of the input ring track 23, so the clothes hanger 200 can be smoothly transferred from the output ring track 24 of the upper-level storage equipment 102 to the input ring track 23 of the lower-level storage equipment 102 for conveying.

[0149] Furthermore, since the warehouse sorting system 100 without fixed shelves also includes an inbound device 101, an outbound device 104, and multiple connecting parts 105, the inbound device 101 and the first storage device 102a, the first storage device 102a and the second storage device 102b, and the second storage device 102b and the outbound device 104 are all connected through the connecting parts 105. Therefore, the clothes hanger 200 can be moved smoothly between the corresponding two devices through the connecting parts 105.

[0150] Furthermore, since the single-piece conveying track (entry ring track 23, output ring track 30) 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 random conveying track (inbound ring track 21, output ring track 24) through a movable off-track assembly 71, and the lower end 722 is connected to the carrying track 63 through a turning guide connecting member 73, the hanger 200 on the random conveying track can be easily transferred to the carrying track 63 of the lower-level conveying track (e.g., ) through the movable off-track assembly 71, the connecting track 72, and the turning guide connecting member 73.

[0151] Furthermore, since the output ring track 24 has an upstream track section 213a that is upstream of the corresponding movable derailment component 71 along the conveying direction D1 of the hanger 200 and an upstream downstream track section 213b that is downstream, and the upstream track section 213a is higher than the upstream downstream track section 213b, the hanger 200 conveyed along the conveying direction D1 to the upstream track section 213a can be guided by its own gravity by the movable derailment component 71 to leave the upstream track section 213a.

[0152] Furthermore, because the entry ring track 23 has an upstream track section 651a and a downstream track section 651b that are upstream of the hanger 200 in the conveying direction D4 compared to the turning guide connecting member 73, and the upstream track section 651a is higher than the downstream track section 651b, and the movable derailment component 71 is higher than the turning guide connecting member 73, the hanger 200 guided by the movable derailment component 71 can still slide down the connecting track 72 by gravity alone and, after being guided by the turning guide connecting member 73, enter the downstream track section 651b of the first entry ring track 23a. This achieves the transfer of the hanger 200 from the first output ring track 24a to the first entry ring track 23a, and this transfer process relies solely on gravity and does not require additional driving force.

[0153] The above embodiments are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.

[0154] For example, in this embodiment, the number of storage devices 102 is set to two. In actual use, the number of storage devices 102 can also be set to one, that is, only the first storage device 102a is set. In this case, the output of the first storage device 102a is directly connected to the outbound device 104 via the ring track 24 and the connecting part 105. In addition, in actual use, the number of storage devices 102 can be set to more than two. The storage line 25 of the upstream storage device 102 is set to 50 to 80, and the number of each of the remaining storage devices 102 is set to 15 to 30. The number of each of the remaining storage devices 102 can be the same or different.

[0155] In this embodiment, although the carrying track 63 is configured 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 positioned above the first end 63a, with a small gap between them, making the entire carrying track 63 approximately looped. 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 entry loop track 23. However, in actual use, the carrying track can also be configured in other non-closed shapes. For example, the first end of the carrying track can be configured with the same structure and position as the first end 63a in this embodiment, while the second end of the carrying track can be positioned downstream of the last gap 631 set along the conveying direction D4', as long as it ensures 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 does not affect the setting of the return track 29.
