Abstract

The present invention provides a fixed-shelf-free warehousing device and a fixed-shelf-free warehousing system, including a goods shelving line, an inbound circular track, a storage-in circular track, and an inbound-storage connection part connecting the two circular tracks. Since there is a goods shelving line, it can bear the goods carriers to be warehoused; since there is an inbound circular track composed of a random-conveyor-type conveying track, the goods carriers from the goods shelving line can randomly enter the inbound circular track. The goods carriers are manually hung on the goods shelving line, so the shelving is not uniform and may be intermittent, and this random-conveyor method meets the actual needs of shelving; since there is a storage-in circular track composed of a single-piece-conveyor-type conveying track, after the goods carriers enter the storage-in circular track, they are conveyed in the form of single pieces, which is more conducive to the goods carriers entering multiple goods storage lines connected to the storage-in circular track in sequence, and the conveying efficiency is high.

Description

Technical Field

[0001] The present invention belongs to the field of goods storage, and relates to a fixed-shelf-free warehousing device and a fixed-shelf-free warehousing system. Background Art

[0002] Currently, the commonly adopted method in goods storage is to place goods in containers and classify the containers on different shelves, and then use conveying equipment to convey goods between different storage areas in the warehousing system. In the above-mentioned goods warehousing system, the erection of shelves is cumbersome, the floor area is large, a large amount of manpower is required for container classification and handling, the conveying equipment requires operating space, and the conveying equipment and its maintenance are also relatively expensive.

[0003] Moreover, when applying such a goods warehousing system to industries where goods are in the form of soft sheets, such as the clothing industry, during the warehousing process, multiple pieces of clothing need to be packed in the same container first. This not only requires manpower and material resources for packing, but also causes the clothing to be stacked and squeezed, resulting in wrinkles. In addition, clothing usually needs to be classified and warehoused and stored according to production batches, attributes, etc. The attributes of clothing are relatively diverse, including materials, sizes, colors, styles, etc. Correspondingly, when classifying, warehousing, and storing clothing, the classification requirements are relatively complex. If manual classification and packing are used for warehousing, it will be very time-consuming and prone to classification errors. Since multiple pieces of clothing are packed in the same container, it is also difficult to detect classification errors. Once a classification error occurs, it is necessary to manually open the container for inspection and repack, which is very inconvenient.

[0004] Therefore, there is an urgent need for a fixed-shelf-free warehousing system that can achieve a fixed-shelf-free state, keep clothing flat, is easy to automate, and reduces warehousing classification errors. Correspondingly, there is also an urgent need for a fixed-shelf-free warehousing device in such a fixed-shelf-free warehousing system for classifying and warehousing goods into storage equipment according to certain warehousing rules.

[0041] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the fixed-shelf-free warehousing device and the fixed-shelf-free warehousing system of the present invention will be specifically described below in conjunction with embodiments and the accompanying drawings.

[0042] The present invention provides a flexible sheet material warehousing system, which can be a clothing warehousing system and uses a hanging rack (i.e., a hanger) as a goods carrier.

[0043] <Example>

[0044] Figure 1 It is a schematic structural diagram of a fixed - shelf - free warehousing system in an embodiment of the invention.

[0045] As Figure 1 shown, the fixed - shelf - free warehousing system 100 of this embodiment is a clothing warehousing system that uses tracks to convey and store a goods carrier (hanger) carrying goods (clothes). It includes an inbound device 101, a storage device 102, a sorting device 103, an outbound device 104, and a plurality of connecting parts 105.

[0046] The inbound device 101 is used to put the hanger carrying clothes into the warehouse. The storage device 102 is used to store (or classify and store) the hangers. The sorting device 103 is used to classify and pick the hangers output by the storage device 102. The outbound device 104 is used to take the hangers sorted by the sorting device 103 out of the warehouse (or further classify and take them out). Figure 1 In, each straight - line segment or loop represents a different track, and the arrows on these lines indicate the moving direction of the goods carrier on the corresponding track.

[0047] In this embodiment, the connecting part 105 is set to three, which are respectively denoted as the inbound - storage connecting part 105a, the storage - sorting connecting part 105b, and the sorting - outbound connecting part 105c. The inbound - storage connecting part 105a, the storage - sorting connecting part 105b, and the sorting - outbound connecting part 105c are respectively arranged between the inbound device 101 and the storage device 102, between the storage device 102 and the sorting device 103, and between the sorting device 103 and the outbound device 104, and are used to connect the tracks of these devices so that the hanger can move between different devices through the connecting part 105.

[0048] In this embodiment, the storage and conveyance of goods between and within each device both adopt the form of tracks. Among them, the inbound device 101 includes an inbound - use circular track 22 that outputs the inbound goods carrier to the next level (i.e., the storage device 102) and a plurality of goods - shelving lines 21 connected to the inbound - use circular track 22. The storage device 102 includes a storage - entry circular track 23 that receives the goods carrier from the inbound device 101 and a plurality of goods - storage lines 25 connected to the storage - entry circular track 23 and used to store the received goods carrier. It can be directly seen from Figure 1 that the inbound - use circular track 22 and the storage - entry circular track 23 of this embodiment are circular tracks, while the goods - storage line 25 is a straight - line track. In addition, the number of goods - storage lines 25 in this embodiment is 100. In the figure, an omission drawing method is adopted, and a part of them is shown.

[0049] Figure 2 Yes Figure 1 It is a structural diagram of the part inside the middle frame A.

[0050] As Figure 2 shown, the fixed-shelf-free warehousing device 110 includes two goods shelving lines 21, an in-warehouse circular track 22, a storage-in circular track 23, and an in-warehouse storage connection part 105a. The storage-in circular track 23 is respectively connected to multiple goods storage lines 25. In this embodiment, the number of goods storage lines 25 is 100.

[0051] Figure 3 It is a connection structural diagram of the goods shelving line and the in-warehouse circular track in the embodiment of the present invention. Figure 4 It is a structural diagram of the goods shelving line in the embodiment of the present invention.

[0052] As Figure 3 and Figure 4 shown, the goods carrier in this embodiment is a clothes hanger 200. The clothes hanger 200 includes a hook 201 and a support part for placing clothes (not shown in the figure). The specific structure can adopt a conventional structure in the prior art. The hook 200 has a hanging-in opening 201a, and the hook 200 is hung into each conveying track through the hanging-in opening 201a.

[0053] The goods shelving line 21 includes an upper line segment 211, an upper line buffer segment 212, a rising segment 213, and an upper line driving part 333. In this embodiment, the upper line segment 211 is located at a low position, which is convenient for operators to hang the clothes hanger 200 onto the upper line segment 211. The upper line buffer segment 212 is at a high position relative to the upper line segment 211 and is approximately at the same height as the in-warehouse circular track 22.

[0054] The upper line segment 211 is used to receive the clothes hanger 200 to be warehoused. The upper line buffer segment 212 is used to guide the clothes hanger 200 received by the upper line segment 211 into the in-warehouse circular track 22. The rising segment 213 is respectively connected to the upper line segment 211 and the upper line buffer segment 212, and is used to lift the clothes hanger 200 on the upper line segment 211 to the upper line buffer segment 212. The upper line segment 211 extends downward and obliquely along the conveying direction of the clothes hanger 200. Therefore, after the clothes hanger 200 is hung at one end of the upper line segment 211, it can slide to the connection part of the upper line segment 211 and the rising segment 213 by gravity. The rising segment 213 extends upward and obliquely along the conveying direction. The upper line buffer segment 212 also extends downward and obliquely along the conveying direction of the clothes hanger 200. Therefore, after the clothes hanger 200 rises to the upper line buffer segment 212, it can also slide to the end of the upper line buffer segment 212 by gravity and further enter the in-warehouse circular track 22 that is approximately at the same height as the upper line buffer segment 212.

[0055] In this embodiment, the online driving part 333 is an elevator arranged on the ascending section 213, and is used to drive the clothes hanger 200 to move from the online section 211 to the online buffer section 212 along the ascending section 213.

[0056] Figure 5 It is a structural diagram of the online blocking part in the embodiment of the present invention.

[0057] As Figure 4 and Figure 5 shown, the fixed-shelf-free warehousing device 110 further includes an online blocking part 332.

[0058] The online blocking part 332 is arranged at the end of the online buffer section 212 close to the warehousing circular track 22, that is, Figure 4 at the position B1 in , and is used to block or release the clothes hanger 200 on the online buffer section 212 that is about to enter the warehousing circular track 22. Specifically, the online blocking part 332 includes a movable stopper 3321 arranged in a groove on the online buffer section 212 and a driving cylinder 3322. The driving cylinder 3322 can drive the movable stopper 3321 to move up and down, so as to realize the blocking or release of the clothes hanger 200.

[0059] Figure 6 It is a structural diagram of the track section of the warehousing circular track in the embodiment of the present invention.

[0060] As Figure 3 and Figure 6 shown, the warehousing circular track 22 is a closed circular track and is composed of a random conveying type conveying track. In this embodiment, the random conveying type conveying track is a format type conveying track. The format type conveying track includes a first placement track 211 and a plurality of "G"-shaped format members 212 with the lower part matching the hooks 201 of the clothes hanger 200 for carrying and conveying the clothes hanger 200. The format members 212 move on the first placement track 211 through pulley groups embedded in the first placement track 211, and the specific installation method is the prior art and will not be elaborated here.

[0061] Figure 6 Only some of the format members 212 are shown in . Actually, a plurality of format members 212 are arranged on the entire closed circular first placement track 211 in the same manner as the format members 212 shown in the figure.

[0062] A warehousing driving part (not shown in the figure) for driving the format members 212 to move is also arranged on the warehousing circular track 22. In this embodiment, the conveying direction of the warehousing circular track 22 is clockwise.

[0063] Figure 7 It is a schematic connection diagram of the goods storage line and the storage entry circular track in the embodiment of the present invention.

[0064] As Figure 7 shown, multiple goods storage lines 25 are respectively connected to the storage-in track 23, and a plurality of shunt components 26 are provided at the connection positions.

[0065] The fixed-shelf-free loading device 110 further includes a connection blocking portion 331 and a storage receiving blocking portion 334.

[0066] The connection blocking portion 331 is embedded in the connection portion 105a between the storage-in rooms, that is, Figure 7 at the position B2 in the figure, and is used to block or release the clothes hangers 200 on the connection portion 105a between the storage-in rooms.

[0067] The storage receiving blocking portion 334 is embedded in the storage-in circular track 23, and is located at the upstream position of the connection between the storage-in circular track 23 and the connection portion 105a between the storage-in rooms, that is, Figure 7 at the position B3 in the figure, and is used to block or release the clothes hangers 200 passing through this position.

[0068] The structures and functions of the connection blocking portion 331 and the storage receiving blocking portion 334 are the same as those of the upstream blocking portion 332, that is, they have a stopper that can be movably installed in the above-mentioned track section and a driving cylinder for driving the stopper, which will not be elaborated here.

[0069] Figure 8 is a structural diagram of the track section of the storage-in circular track for goods in the embodiment of the present invention.

[0070] As Figure 7 and Figure 8 shown, the storage-in circular track 23 is a closed circular track and is composed of a single-piece conveying type conveying track. In this embodiment, the single-piece conveying type conveying track is a bird-hook type conveying track. The bird-hook type conveying track includes a plurality of bird-hook type conveying units 61, guide rails 62, and a carrying track 63. A plurality of bird-hook type conveying units 61 are arranged on the guide rails 62 and the carrying track 63. The guide rails 62 play a supporting role and are in a closed circular shape; the carrying track 63 is arranged on the guide rails 62 and is correspondingly arranged below the guide rails 62. The conveying direction of the storage-in circular track 23 is opposite to the conveying direction of the storage-in circular track 22, that is, counterclockwise.

[0071] Figure 9 is a structural diagram of the state where a plurality of bird-hook type conveying units are connected in sequence in the embodiment of the present invention.

[0072] Figure 10 is an exploded view of the structure of the bird-hook type conveying unit in the embodiment of the present invention.

[0073] As Figure 9 and Figure 10As 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.

[0074] The bird hook 11 has a bird hook body 111 and a pulling groove 111a provided at the rear of the bird hook body 111.

[0075] Among them, the length direction of the bird hook 111 is basically the same as the conveying direction. The lower edge of the front part of the bird hook body 111 is an inclined edge that gradually inclines backward from top to bottom. The pulling groove 111a is used to hook the hook of the clothes hanger 200, and its shape is adapted to the hook 201.

[0076] In this embodiment, the bird hook seat 12 is used to install the bird hook 11. The bird hook seat 12 has a strip-shaped seat body 121, a mounting portion, and two connecting ends 122.

[0077] Among them, the seat body 121 is strip-shaped, and its length direction is the same as the front-rear direction. The mounting portion includes two mounting plates 123 that extend downward from both sides of the bottom of the seat body 121. Four mounting holes 124 are provided on each mounting plate 123. At the same time, the mounting holes 124 on the two mounting plates 123 are arranged opposite to each other, that is, a total of four pairs of mounting holes 124 are provided on the two mounting plates 123.

[0078] The bird hook 11 is installed through two pairs of mounting holes 124 at the front, restricting the rotatable degree of the bird hook 11 within the positions corresponding to both ends of the long axis of the limiting hole 113.

[0079] The reset member 13 is a spring. One end of it is fixed at the position between the two mounting plates 123 on the bottom surface of the seat body 121, 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. Thus, when the bird hook 11 is not subject to external force, it abuts against the bearing track 63 located below it due to the spring force of the reset member 13.

[0080] When the clothes hanger 200 enters the carrying track 63 from the connection part 105a of the storage room for incoming goods, once the bird hook 11 moves forward from the rear side of the clothes hanger 200, the hook 201 of the clothes 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 an inclined edge that gradually slopes backward from top to bottom, the bird hook body 111 will not drive the clothes hanger 200 to move forward, but will tilt upward around the shaft hole 112. When the bird hook 11 continues to move forward, when the pulling groove 111a reaches the clothes hanger 200 and there is no other clothes hanger 200 on the carrying 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 clothes hanger 200 is hooked by the pulling groove 111a, so that it can be pulled forward by the bird hook 11. In addition, since the size of the pulling groove 111a matches the hook of the clothes hanger 200, it can only hook one clothes hanger 200 at a time and pull it forward. The clothes hanger 200 that has not been pulled away will stay in place and be pulled away by the next bird hook 11.

[0081] The two connection ends 122 are respectively located at the front and rear ends of the seat body 121, and are respectively used to connect two bird hook seats 12 adjacent to the bird hook seat 12 in the conveying direction. For the convenience of description, they are denoted as the front connection end 122A and the rear connection end 122B.

[0082] When a plurality of 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, the moving assembly 15 is also arranged at the connecting member 62.

[0083] The moving member 15 is arranged at the front connection end 122A of the bird hook seat 12 and includes a roller frame 151 and a roller assembly installed on the roller frame 151.

[0084] When two adjacent bird hook conveying units 61 are connected, the front connection end 122A of the latter bird hook conveying unit 61 is connected to the rear connection end 122B of the former bird hook conveying unit 61 through the connecting member 14 and the central through shaft 152. The two adjacent bird hook seats 12 can rotate left and right and up and down at the same time, that is, the relative rotation between the two has two degrees of freedom.

[0086] As Figure 11 shown, the function of the moving member 15 is to move the bird hook seat 12, and the roller assembly therein includes a load-bearing roller 153, a moving wheel shaft 154, a guiding roller 155, and a guiding wheel mounting portion 156.

[0087] Among them, the moving wheel shaft 154 is arranged at the top of the roller frame 151 and extends in the left - right direction. The number of load - bearing rollers 153 is two, which are respectively installed on both sides of the moving wheel shaft 154, and the central axes of both are along the left - right direction.

[0088] The number of guide wheel mounting parts 156 is two, and the two guide wheel mounting parts 156 are arranged in the middle of the roller frame 151 and arranged in the front - back direction. The number of guide rollers 155 is also two, which are respectively installed on the guide wheel mounting parts 156, and the axes of both are along the up - down direction.

[0089] The lower part of the guide rail 62 has an opening, and there are load - bearing flanges 621 extending inwards on both sides of the opening. The two load - bearing flanges 621 are distributed on the guide rail 62 in the front - back direction, and the two load - bearing rollers 153 are respectively located on the two load - bearing flanges 621 and can slide in the front - back direction on the load - bearing flanges 621.

[0090] On the inner sides of the two load - bearing flanges 621, there are also guide flanges 622 extending downwards. The guide rollers 155 are located between the two guide flanges 622 and can contact the guide flanges 622, so that the moving member 15 is not likely to deviate when moving.

[0091] On the storage - entering annular track 23 of this embodiment, there is also an entering driving part 64 for driving the movement of each hook conveying unit 61. The entering driving part 64 includes a driving motor 641, a first driving wheel 642, and a second driving wheel 643.

[0092] The driving motor 641 is fixedly installed near the guide rail 62.

[0093] The first driving wheel 642 and the second driving wheel 643 are respectively installed on both sides of the guide rail 62, and the central axes of both are along the vertical direction; at the same time, the surfaces of the first driving wheel 642 and the second driving wheel 643 respectively abut against the two side surfaces of the hook seat 12, so that the hook seat 12 is "clamped" from both sides by the first driving wheel 642 and the second driving wheel 643. The first driving wheel 642 is connected to the output shaft of the driving motor 641 through a transmission mechanism and can rotate under the drive of the driving motor 641. When the first driving wheel 642 rotates, it drives the hook seat 12 in contact with it to move through friction. When the next hook seat 12 moves, it continues to abut against the first driving wheel 642 and is thus continuously driven by the first driving wheel 642 to move. During the movement, the second driving wheel 643 abuts against the hook seat 12 from the opposite side of the first driving wheel 642 and is driven to rotate together by the friction of the hook seat 12, playing a role in stabilizing the hook seat 12.

[0094] In this embodiment, since the moving member 15 is coupled to the connecting member 14 through the central through-axis 152, and the connecting member 14 connects two adjacent hook seats 12, when each load-bearing roller 153 moves forward under the drive of the entering driving part 64, it drives each hook seat 12 to move forward, and the hook 11 moves forward, so as to be able to hook the clothes hanger 200 and pull it forward. In addition, the structure of the warehousing driving part is similar to that of the entering driving part 64. The warehousing driving part also drives the long chain-like structure formed by the sequential connection of the driving wheels in the front and back directions by the motor. The specific details are not described herein again.

[0095] Figure 12 is Figure 7 The structural diagram of the inner part of the middle frame C. To clearly illustrate the structure and function of the diversion component in the structure inside the frame C, the structure of the inner part of the frame C is enlarged and rotated to obtain Figure 12 .

[0096] As Figure 12 shown, a plurality of notches 631 are provided on the carrying track 63. The carrying track 63 has a notch front end and a notch rear end corresponding to each notch 631. Among them, the notch front end is located in front of the notch 631, and the notch rear end is located in front of the notch 631. The storage device 102 further includes a plurality of diversion components 26. The plurality of diversion components 26 are provided at the plurality of notches 631 one by one, and are also connected to the plurality of goods storage lines 25 one by one. That is, the entering annular track 31 is connected to the corresponding goods storage line 25 through the diversion component 26. The plurality of goods storage lines 25 are arranged substantially in parallel.

[0097] The diversion component 26 includes a connecting track section 341, a telescopic track section 342, and a telescopic driving part (not shown in the figure).

[0098] The connecting track section 341 is provided on the notch front end of the carrying track 63 and is connected to the corresponding goods storage line 25.

[0099] The telescopic track section 342 is provided on the notch rear end of the carrying track 63 and can extend a section of track under the drive of the telescopic driving part, and the extended section of track fits with the connecting track section 341, so that the corresponding notch 631 is in a closed state. At this time, when the clothes hanger 200 conveyed on the storage entering annular track 23 passes through the diversion component 26, it will still continue to move forward along the conveying direction and will not enter the corresponding goods storage line 25; in addition, the telescopic track section 342 can also retract the extended section of track under the drive of the telescopic driving part, so that the corresponding notch 631 is in an open state. At this time, when the clothes hanger 200 conveyed along the conveying direction passes through the diversion component 26, it will directly enter the corresponding goods storage line 25 through the notch 631.

[0100] In the above manner, through the goods loading line 21, the inbound circular track 22, the connection part 105a of the inbound storage room, the storage entry circular track 23, a plurality of shunt components 26, and a plurality of goods storage lines 25, the purpose of classified inbound storage can be achieved.

[0101] Figure 13 Yes Figure 2 It is an enlarged structure diagram of the inner part of the middle frame B. To clearly illustrate the structure of the connection part 105a of the inbound storage room, the structure in Figure 13 is rotated to obtain Figure 14 , Figure 14 Yes Figure 2 It is a structure diagram of different angles of the inner part of the middle frame B.

[0102] As Figure 13 and Figure 14 shown, the inbound circular track 22 has an inbound side connection track section 213 that is arranged adjacent to the storage device 102 and extends obliquely downward. The angle between the inbound side connection track section 213 and the horizontal direction is 29°. The conveying direction on the inbound side connection track section 213 is Figure 4 the direction indicated by the arrow D1 in

[0103] Hereinafter referred to as the conveying direction D1. The storage entry circular track 23 has a storage entry side connection track section 65 that is arranged adjacent to the inbound device 101 and extends obliquely downward. The storage entry side connection track section 65 is arranged in parallel with the inbound side connection track section 213. The conveying direction on the storage entry side connection track section 65 is Figure 4 the direction indicated by the arrow D4 in

[0104] The bearing track 63 is set to be non-circular and can receive the hanger 200 from the inbound device 101 at the connection part 105a of the inbound storage room.

[0105] The connection part 105a of the inbound storage room is arranged between the inbound device 101 and the storage device 102 and is used to guide the hanger 200 to naturally slide from the inbound circular track 22 to the storage entry circular track 23 without relying on any driving structure but only by gravity. It includes a rail separation component 71, a connection track 72, and a guiding connection member 73.

[0106] The connection track 72 has two ends, namely the upper-level end 721 and the lower-level end 722. The upper-level end 721 of the connection track 72 is connected to the guiding transfer member 712, and the lower-level end 722 of the connection track 72 is connected to the turning guiding connection member 73.

[0107] Figure 15It is a schematic structural diagram of the connecting track in the embodiment of the present invention. Figure 16 It is a schematic structural diagram of the track body of the connecting track in the embodiment of the present invention.

[0108] As Figure 15 and Figure 16 shown, the connecting track 72 has a track body 55, a mounting portion 51, and two lining strips 52.

[0109] The track body 55 is a straight track section integrally formed by aluminum profiles. The track body 55 includes two side support portions 53 and a top support portion 54.

[0110] The two side support portions 53 are oppositely arranged, and their cross-sections are L-shaped, and the thicknesses of the two side support portions 53 gradually become thicker from top to bottom, that is, the two side walls of the track body 55 gradually become thicker from top to bottom, which makes the overall center of gravity of the track body 55 move downward and is more stable in use.

[0111] The two side support portions 53 respectively extend downward from the top support portion 54, and two flanges 553 are respectively arranged on the inner surfaces of the two side support portions 53 facing each other and protrude inward. Thus, a receiving cavity 552 extending in the length direction of the track body 55 and a through opening 551 communicating with the receiving cavity 552 are formed between the top support portion 54 and the two side support portions 53. The width of the receiving cavity 552 is greater than the width of the through opening 551. The receiving cavity 552 and the through opening 551 form a tubular cavity and a limiting structure inside the track body 55. The tubular cavity can be used to place a cylinder, and the limiting structure can be used to fixedly install other components through bolts and nuts whose shape and size are adapted thereto.

[0112] The top support portion 54 is respectively combined with the top end portions of the two side support portions 53. The top support portion 54 has two inclined surface portions 541 axially symmetrically distributed along the length direction of the track body 55, and a flat surface portion 542 located between the two inclined surface portions 541.

[0113] The mounting portion 51 is arranged on the top of the track body 55 and is integrally formed with the track body 55. The mounting portion 51 has two mounting grooves 503 and a positioning groove 504.

[0114] The two mounting grooves 503 are respectively arranged on the two inclined surface portions 541 and extend along the length direction of the track body 55. Therefore, the two mounting grooves 503 are also axially symmetrically distributed along the length direction of the track body 55.

[0115] The installation groove 503 has an abutting surface 5032, an opening 5033, and two inner ends 5031. The width of the opening 5033 is smaller than the width of the abutting surface 5032, thereby forming the two inner ends 5031. The two inner ends 5031 are respectively located on both sides of the installation groove 503.

[0116] The positioning groove 504 is provided on the planar portion 542 and extends along the length direction of the rail body 55.

[0117] The two lining strips 52 are respectively fitted and installed in the two installation grooves 503, and the top 521 of the lining strip 52 protrudes outward from the installation groove 503. Therefore, when the clothes hanger 200 slides on the connecting rail 72, the clothes hanger 200 only contacts the two lining strips 52. Since the two lining strips 52 support the clothes hanger 200 simultaneously, the clothes hanger 200 can move stably on the connecting rail 72 and is not prone to shaking. And because the material of the lining strip 52 is PA66 plastic, the friction coefficient of the outer surface of the lining strip 52 is small, making the movement of the clothes hanger 200 on it smoother.

[0118] One end of the connecting rail 72 serves as the upper-stage end 721 and is connected to the guiding transfer member 712, and the other end serves as the lower-stage end 722 and is connected to the carrying rail 63 through the turning guiding connecting member 73. The position of the upper-stage end 721 is higher than that of the lower-stage end 722, so that after the clothes hanger 200 leaves the guiding transfer member 712, it can naturally slide along the length direction of the connecting rail 72 towards the storage inlet side connecting rail section 65 only by gravity.

[0119] The inclination angle of the connecting rail 72 is determined according to the total mass of the clothes hanger 200 and the clothing. Generally, it is selected between 10° and 60°. When the weight is heavier, this angle needs to be set smaller to avoid too fast a cargo transfer speed; when the weight is lighter, this angle needs to be set larger to avoid being stuck due to resistance when the cargo descends and cannot be transferred normally. In this embodiment, calculated based on a total weight of 1.5 kg, the included angle between the connecting rail 72 and the horizontal direction is 20°.

[0120] Figure 17 Yes Figure 14 An enlarged view of the inner part of the middle frame D. Figure 18 It is a structural diagram of the off-rail assembly in the embodiment of the present invention. Figure 19 It is a structural diagram of the guiding transfer member in the embodiment of the present invention.

[0121] As Figure 17 - 19 Shown, the off-rail assembly 71 has an off-rail member 711 and a guiding transfer member 712.

[0122] The derailing member 711 has an integrally formed mounting portion 84 and a derailing portion 85. The material of the derailing member 711 is Q235 steel with white zinc plating on the surface, and the overall thickness is 4 mm.

[0123] The derailing portion 85 is located on the side of the incoming-side connecting rail section 213 close to the storage entry ring rail 23, that is, outside the ring of the incoming-ring rail 22, and is used to disengage the hanger 200 from the incoming-side connecting rail section 213 to the guiding and transferring member 712. The side surface of the derailing portion 85 is trapezoid-like, and the two bottom angles of this trapezoid-like shape are rounded and extend outwards respectively.

[0124] The derailing portion 85 has an inclined portion 851 that gradually deviates along the conveying direction D1. The inclined portion 851 is located at the lower bottom of the trapezoid-like shape, and its extending direction is Figure 14 the D2 direction shown, that is, the deviation transfer direction.

[0125] The guiding and transferring member 712 is used to guide and transfer the hanger 200 disengaged from the derailing portion 85 to the connecting rail 72. The guiding and transferring member 712 has a first main guiding section 81, an introducing end portion 82, and a discharging end portion 83.

[0126] The introducing end portion 82, the first main guiding section 81, and the discharging end portion 83 of the guiding and transferring member 712 are integrally formed and are made of a material composed of PA plastic and glass fiber.

[0127] The first main guiding section 81 gradually bends towards the storage entry ring rail 23 in the length direction and also gradually bends downwards. Guiding protrusions are respectively formed on both sides of the top of the first main guiding section 81. The guiding protrusions extend along the length direction of the first main guiding section 81 and can match the hanger 200, enabling the hanger 200 to slide smoothly on the first main guiding section 81.

[0128] The introducing end portion 82 is arranged at one end of the first main guiding section 81 and extends along the direction close to the derailing portion 85 with a gradually decreasing width. Under the action of its own gravity, the hanger 200 naturally slides into the guiding and transferring member 712 after leaving the incoming-side connecting rail section 213 through the derailing member 711.

[0129] In addition, the shapes of the two protrusions 813 of the first main guiding section 81 and the two lining strips 52 of the connecting rail 72 are the same, and when the connecting rail 72 is connected to the guiding and transferring member 712, the two protrusions 813 are respectively aligned with the two lining strips 52 of the connecting rail 72, thereby forming a continuous strip-shaped supporting structure.

[0130] Figure 20 It is the connection structure diagram of the downstream part of the connection part between the incoming storage rooms in the embodiment of the present invention. Figure 21 It is the structural schematic diagram of the turning guiding and connecting member in the embodiment of the present invention.

[0131] As Figure 20 and Figure 21 shown, the turning guide connection member 73 includes a second main guide section 91 and two connection end portions 92. In this embodiment, the second main guide section 91 and the two connection end portions 92 are integrally formed, and the material thereof is a mixture of polyamide 66 and glass fiber. The second main guide section 91 is curved in the length direction.

[0132] The two connection end portions 92 are respectively used to connect the next-stage end portion 722 of the connection track 72 and the load-bearing track 63.

[0133] The track structure of the load-bearing track 63 is the same as that of the connection track 72, and the difference between the two is only the track arrangement. Therefore, the load-bearing track 63 also has two lining strips provided at the top and a positioning groove provided between the two lining strips.

[0134] In addition, the two lining strips of the load-bearing track 63 are the same in shape as the two protrusions 911 of the second main guide section 91 and the two lining strips 52 of the connection track 72. When the load-bearing track 63 and the connection track 72 are connected to the turning guide connection member 73, the two lining strips of the load-bearing track 63 are respectively aligned with the two guiding protrusions, and the two guiding protrusions are also respectively aligned with the two lining strips 52 of the connection track 72, thereby forming a continuous strip-shaped supporting structure.

[0135] The structure of the track section of the goods storage line 25 and the storage entry circular track 23 is the same, which is a bird-hook type conveying track, and will not be described in detail here.

[0136] Functions and effects of the embodiment

[0137] According to the rackless warehousing entry device 110 and the rackless warehousing system 100 provided in this embodiment, it includes a goods loading line 21, an entry circular track 22, a storage entry circular track 23, and an entry-storage connection part 105a connecting the two circular tracks. Since there are multiple goods loading lines 21, multiple hangers 200 to be warehoused can be received simultaneously; since the entry circular track 22 is composed of a random-type conveying track, the hangers 200 from the goods loading line 21 can randomly enter the entry circular track 22. The hangers 200 are hung on the goods loading line 21 manually, so the loading is not uniform and may be intermittent. This random conveying method meets the actual needs of loading; since the storage entry circular track 23 is composed of a single-piece conveying track, after the hangers 200 enter the storage entry circular track 23, they are conveyed in the form of single pieces. The single-piece form is more conducive to the hangers 200 entering the multiple goods storage lines 25 connected to the storage entry circular track 23 in sequence, and the conveying efficiency is high. Therefore, the rackless warehousing entry device 110 of this embodiment can receive multiple hangers 200 to be warehoused simultaneously and warehouse them into multiple goods storage lines 25, and the conveying efficiency is high. In addition, since the rackless warehousing system 100 of the present invention uses a track form for conveying and storage, there is no need to set up fixed racks, nor is it necessary to additionally equip conveying equipment, which is easy to build and has a low cost.

[0138] Specifically, since the goods loading line 21 has a lower loading section 211, a higher loading buffer section 212, and an ascending section 213 connecting the two, it is convenient for the operator to hang the hanger 200 on one end of the loading section 211, and the loading section 211 extends downward obliquely along the conveying direction of the hanger 200. Therefore, the hanger 200 hung on the loading section 211 can slide to the connection between the loading section 211 and the ascending section 213 by gravity. The ascending section 213 extends upward obliquely along the conveying direction of the hanger 200 and is provided with a hoist, so the hanger 200 can be lifted to the loading buffer section 212. The loading buffer section 212 is approximately at the same height as the entry circular track 22 and extends downward obliquely along the conveying direction of the hanger 200. Therefore, the hanger 200 can slide to the entry circular track 22 connected to the loading buffer section 212 by gravity. In addition, since a loading blocking part 331 is embedded on the loading buffer section 212, the hanger 200 passing through here can be blocked or released according to actual needs.

[0139] Furthermore, the annular track 22 for warehousing is a closed annular track and is composed of a format-type conveying track, and has a driving part for warehousing. Therefore, it can drive the hanger 200 to move on the annular track 22 for warehousing, and can well achieve the purpose of random conveying; the annular track 23 for storage entry is a closed annular track and is composed of a bird-hook type conveying track, and has an entry driving part 64. Therefore, it can also drive the hanger 200 to move on the annular track 23 for storage entry, and can well achieve the purpose of single-piece conveying. The annular track 23 for storage entry is also embedded with a storage receiving blocking part 334, specifically located at the upstream position of the connection between the annular track 23 for storage entry and the connection part 105a between the warehousing and storage. Therefore, the hanger 200 passing through this position can be blocked or released according to actual needs.

[0140] Furthermore, since the warehousing device 110 without a fixed shelf also has a plurality of shunt components 26, which are respectively arranged at the connections between the annular track 23 for storage entry and the respective goods storage lines 25. The shunt component 26 has a connecting track section 341 fixedly connected to the annular track 23 for storage entry and a telescopic track section 342 telescopically installed on the connecting track section. Therefore, it can connect or disconnect the annular track 23 for storage entry and the goods storage line 25, so that the hanger 200 can enter the corresponding goods storage line 25 or be blocked. When the hanger 200 is blocked by a shunt component 26, it will continue to move along the annular track 23 for storage entry until it reaches the position of the next shunt component 26. Therefore, by connecting or disconnecting the shunt component 26, the hanger 200 can enter the goods storage line 25 where it should be stored.

[0141] Furthermore, the connection part 105a between the warehousing and storage has a connecting track 72, a derailing component 71 and a turning guiding connecting member 73. The connecting track 72 has an upper-stage end 721 and a lower-stage end 722. Since the connecting track 72 has an inclination angle, that is, there is a height difference between the two ends of the connecting track 72, and the upper-stage end 721 is higher than the lower-stage end 722. Therefore, the hanger 200 can slide from the upper-stage end 721 to the lower-stage end 722 by relying on gravity. The upper-stage end 721 is connected to the guiding transfer member 712 and is connected to the annular track 22 for warehousing through the derailing component 71. The lower-stage end 722 is connected to the turning guiding connecting member 73 and is connected to the carrying track 63 through the turning guiding connecting member 73. Therefore, the hanger 200 can be transferred from the annular track 22 for warehousing to the annular track 23 for storage entry through the connection part 105a between the warehousing and storage by relying on gravity without additional driving force. In addition, a connection blocking part 331 is also embedded on the connection part 105a between the warehousing and storage. Therefore, the hanger 200 passing through this position can be blocked or released according to actual needs.

[0142] The above embodiments are only used to illustrate the specific implementation manners of the present invention, and the present invention is not limited to the description scope of the above embodiments.

[0143] In the above embodiment, the number of the goods loading lines 21 is two. In other solutions of the present invention, the number of the goods loading lines 21 may also be one or more, and the technical effects of the present invention can also be achieved.

[0144] In the above embodiment, the number of the goods storage lines 25 is one hundred. In other solutions of the present invention, the number of the goods storage lines 25 may also be less or more, and the technical effects of the present invention can also be achieved.
