Description

TECHNICAL FIELD

[0001] The present application belongs to the field of goods storage, and particularly relates to a fixed-shelf-free sorting system. BACKGROUND

[0002] At present, a commonly used mode in goods storage is to erect large-area shelves, place goods in boxes, and then place the boxes on the shelves in a classified manner, and use conveying equipment to convey goods between different storage devices in the storage system. In the above-mentioned goods storage system, the shelves are complicated to erect, have a large floor area, and the classification and carrying of the boxes require a large amount of manpower, and the conveying equipment also requires operating space, so there are problems of complicated shelf erection and high cost of shelves and conveying equipment.

[0003] Moreover, when such a goods storage system is applied to some industries in which goods are in the form of soft sheet materials, such as the clothing industry, it is necessary to first pack multiple pieces of clothing in the same box during the warehousing process, which not only requires manpower and material resources for packing, but also causes the clothing to be stacked and pressed, resulting in wrinkles. In addition, the attributes of clothing are very diverse, including production batch, order information, size, color, style, material, etc., and usually need to go through multiple levels of classification and sorting before being packed and shipped. If manual sorting is used, it will be very time-consuming and labor-intensive, and because of the multiple sorting attributes and complex sorting requirements, it is easy to make classification errors. Since multiple pieces of clothing are packed into the same box, when a classification error occurs, it is necessary to manually open the box and check it, and then repack it, which is very time-consuming and inconvenient.

[0004] Therefore, a fixed-shelf-free sorting system that can realize fixed-shelf-free storage, keep clothing flat, and easily realize automation and reduce warehousing classification errors is an urgent need in the current clothing storage industry. At the same time, existing sorting systems often only have single-level sorting function and are difficult to meet the multi-level sorting needs of the clothing storage industry due to the diverse attributes of clothing.

[0067] Table 1 Goods Information Storage Table

[0068]

[0069] Figure 3 This is a structural diagram of the cargo loading line in an embodiment of the present invention.

[0070] like Figure 3 As shown, the cargo carrier in this embodiment is a clothes hanger 200, which includes a hook 201 and a support part for holding clothing (not shown in the figure). The specific structure adopts a conventional structure in the prior art. The hook 201 has a hook-in opening 201a, through which the hook 201 is hooked to each conveyor track.

[0071] The goods loading line 21 includes an loading section 211, a loading buffer section 212, an ascending section 213, a loading drive unit 333, and a loading stop unit 332.

[0072] The upper section 211 is used to receive the hangers 200 to be put into storage. The upper section 211 is located at a relatively low position, which makes it easy for the operator to hang the hangers 200 on the upper section 211. The upper section 211 extends downward at an incline along the conveying direction of the hangers 200. Therefore, after the hangers 200 are hung on one end of the upper section 211, they can slide to the connection between the upper section 211 and the rising section 213 by gravity.

[0073] The upper buffer section 212 is used to guide the hanger 200 received by the upper section 211 into the receiving ring track 22. The upper buffer section 212 is located at a relatively high position, and the end of the upper buffer section 212 near the receiving ring track 22 is at the same height as the receiving ring track 22. The upper buffer section 212 also extends downward along the conveying direction of the hanger 200. Therefore, after the hanger 200 reaches the upper buffer section 212, it can slide by gravity and enter the receiving ring track 22.

[0074] The rising section 213 is connected to the upper line section 211 and the upper line buffer section 212 respectively, and is used to make the hanger 200 on the upper line section 211 rise along the rising section 213 to the upper line buffer section 212. The rising section 213 extends upward at an angle along the conveying direction.

[0075] The upper drive unit 333 is used to drive the clothes hanger 200 that reaches the connection between the upper section 211 and the rising section 213 to move along the rising section 213 to the upper buffer section 212. In this embodiment, the upper drive unit 333 is a hoist installed on the rising section 213.

[0076] The vehicle identification code reader 311 is installed at the beginning of the upper segment 211 of the cargo loading line 21, that is... Figure 3 At position B1, the vehicle identification code reader 311 is used to read the vehicle identification code of the hanger 200 to obtain the vehicle identification code. In this embodiment, the hanger 200 is equipped with an RFID tag containing a vehicle identification code; the vehicle identification code reader 311 is a handheld RFID reader, which can be used by an operator to read the RFID tag and obtain the vehicle identification code.

[0077] The cargo identification information reader 312 is located at the beginning of the upper segment 211 of the cargo loading line 21, and is located at approximately the same position as the vehicle identification code reader 311. Figure 3 At position B1, the goods identification information reader 312 is used to read the identification information of the clothes on the clothes hanger 200 to obtain the goods identification information of the clothes. In this embodiment, the clothes are provided with a label containing a QR code, which corresponds one-to-one with the goods identification information (i.e., identification code) of the clothes; the goods identification information reader 312 is a handheld barcode scanner, which the operator can hold to read the clothing label to obtain the corresponding goods identification information.

[0078] After the vehicle identification code reader 311 reads the vehicle identification code and the cargo identification information reader 312 reads the cargo identification information, the operator inputs the vehicle identification code and cargo identification information one by one through the operation terminal. The warehouse control unit 301 then controls the information storage unit 34 to store the vehicle identification code of the hanger 200 and the cargo identification information of the clothing accordingly, so as to realize the binding of the clothing and the hanger 200.

[0079] Figure 4 This is a schematic diagram of the sorting transfer mechanism in the first-level sorting equipment of this invention.

[0080] like Figure 4 As shown, in the first-stage sorting equipment 102, the sorting transfer mechanism 106 includes a receiving ring track 22, a sorting ring track 23, and a sorting connecting line 35.

[0081] Figure 5 yes Figure 4 Enlarged view of the inner part of frame A.

[0082] like Figure 5As shown, the receiving ring track 22 is a closed ring track and is composed of a random conveying type conveying track. In this embodiment, the random conveying type conveying track is a formatted conveying track. This random conveying type conveying track in this embodiment is a formatted conveying track, containing multiple formatted components 222. The formatted components 222 are used to carry and convey the hangers 200. Their lower parts are "G"-shaped, cooperating with the hooks of the hangers 200, and their upper parts are pulleys (not shown) that can be accommodated within the track section of the carrying track 221 of the receiving ring track 22. The formatted components 222 move along the receiving ring track 22 via the pulley system embedded in the receiving ring track 22. Figure 5 Move in the direction indicated by the middle arrow D1. Figure 5 Only a portion of the format component 222 is shown; in reality, multiple format components 222 are displayed according to... Figure 5 The format components 222 shown in the image are arranged in the same manner on the entire closed loop mounting track 221.

[0083] The receiving ring track 22 also has a receiving drive unit (not shown in the figure) for driving the movement of the various format components 222. The receiving drive unit has a drive motor and multiple drive wheels, and its specific structure can adopt a conventional structure in the prior art.

[0084] The sorting ring track 23 is also a closed ring track, and it is composed of a single-piece conveying track. In this embodiment, the single-piece conveying track is a birdhook-type conveying track. The birdhook-type conveying track includes a plurality of birdhook-type conveying units 61, guide rails 62, and a support track 63. The support track 63 is used to support the hanger 200, and its portion near the sorting connecting line 35 is straight. The birdhook-type conveying unit 61 is used to hook the hook 201 of the hanger 200 and convey the hanger 200. The birdhook-type conveying unit 61 has a birdhook seat, and a birdhook that can hook the hook 201 and pull it is installed below the birdhook seat. A pulley assembly (not shown in the figure) is installed above the birdhook seat and housed in the guide rail 62 of the sorting ring track 23. The birdhook-type conveying unit 61 moves along the sorting ring track 23 via the pulley assembly. Figure 5 Move in the direction indicated by the middle arrow D3.

[0085] The sorting ring track 23 also has a sorting drive unit (not shown in the figure) for driving the movement of each hook-type conveyor unit 61. The sorting drive unit has a drive motor and multiple drive wheels, and the specific structure can adopt the conventional structure in the prior art.

[0086] The connection line 35 for sorting is arranged between the receiving circular track 22 and the sorting circular track 23, and is used to guide the hanger 200 to transfer from the receiving circular track 22 to the sorting circular track 23. The connection line 35 for sorting is a kind of connection part, which comprises a connection track 72, a guide transfer member 712 and a corner guide connection member 73.

[0087] The connection track 72 has an upper end 721 and a lower end 722, the upper end 721 is connected to the guide transfer member 712, and the lower end 722 is connected to the corner guide connection member 73. As shown in Figure 5 The upper end 721 is arranged higher than the lower end 722, so that the connection track 72 is inclined downward along the conveying direction, thus the hanger 200 can slide from the upper end 721 to the lower end 722 by gravity without additional driving force after entering the connection track 72. In this embodiment, the inclination angle of the connection track 72 is set to 20° according to the conveying requirement of 1.5 kg, so that the sliding speed of the hanger 200 is moderate, which will not be too slow to cause low conveying efficiency, nor too fast to cause unstable conveying of the hanger 200.

[0088] Figure 6 is Figure 5 An enlarged view of the inner part of the middle frame C.

[0089] As shown in Figure 5 and Figure 6 The upper end 721 of the connection track 72 is connected to the guide transfer member 712, and further connected to the off-track member 711 on the receiving circular track 22. The guide transfer member 712 has a gradually widened leading end 82 along the conveying direction, a first main guide section 81 with a certain curvature, and a trailing end 83 matched with the connection track. The off-track member 711 has an off-track part 85 with a slope connected to the leading end 82 of the guide transfer member 712. Therefore, the hanger 200 on the receiving circular track 22 can be guided to turn by the slope when moving to the off-track part 85 of the format conveying track, so as to leave the receiving circular track 22, and then the hanger 200 is guided to turn by the first main guide section 81 of the guide transfer member 712, and then transferred to the connection track 72 to move along Figure 7 The direction indicated by the arrow D2 in

[0090] The lower end 722 of the connection track 72 is connected to the bearing track 63 of the sorting circular track 23 through the corner guide connection member 73. The corner guide connection member 73 has two connection ends matched with the connection track 72, and a second main guide section with a certain curvature, and the bearing track 63 is consistent with the structure of the connection track 72, so the two connection ends are also matched with the bearing track 63.

[0091] After the hanger 200 slides to the next end 722, it is guided to the carrying track 63 through the curved guiding connecting member 73, and is further hooked by the bird hook type conveying unit 61 on the guide rail 62, and is moved along the sorting annular track 23 by the bird hook type conveying unit 61 in the direction indicated by an arrow D3. Figure 5

[0092] Figure 7 Fig. 7 is a structural view of a connection between a sorting transfer mechanism and a goods sorting line in a first stage sorting device in an embodiment of the present application.

[0093] As shown in Fig. 7, in the first stage sorting device 102, one end of each of the plurality of goods sorting lines 29i is connected to the sorting annular track 23 in sequence, and the goods sorting lines 29i are sequentially marked as a goods sorting line 291, a goods sorting line 292, …, a goods sorting line 29i, …, a goods sorting line 29m in the direction indicated by an arrow D5, i.e., the conveying direction of the hanger 200, where m = 30 in this embodiment. Figure 7 Figure 7

[0094] The goods sorting line 29i is also a bird hook type conveying track, and will not be described again. The hanger 200 moves along the goods sorting line 29i in the direction indicated by an arrow D6. Figure 7

[0095] Figure 8 Fig. 8 is an enlarged view of a part of the frame B. Figure 7

[0096] As shown in Fig. 8, the sorting transfer mechanism 106 further includes m sorting and splitting assemblies 26i, which are respectively arranged at the connection between the sorting annular track 23 and each of the goods sorting lines 29i, and can connect or disconnect the sorting annular track 23 and the corresponding goods sorting line 29i. Figure 8

[0097] The sorting and splitting assembly 26i includes a connecting track segment 341, an extension and retraction track segment 342, and an extension and retraction driving member (not shown in the figure).

[0098] ​​​​​​The telescopic rail section 342 is arranged on the rear end of the gap of the carrying rail 63, and can be driven by the telescopic drive to extend a section of the rail, and the extended section of the rail is in abutment with the connecting rail section 341, so that the corresponding gap 631 is in the closed state, at this time, the hanger 200 conveyed on the sorting annular rail 23 will continue to move forward when passing through the sorting and distributing assembly 26i, and will not enter the corresponding goods storage line 29i; in addition, the telescopic rail section 342 can also be driven by the telescopic drive to retract the extended section of the rail, so that the corresponding gap 631 is in the open state, at this time, the hanger 200 will directly enter the corresponding goods storage line 29i through the gap 631 when passing through the sorting and distributing assembly 26i.

[0099] Figure 9 is Figure 7 an enlarged view of the inner part of the middle frame D. In order to clearly show the structure of this part, the structure of the inner part of the middle frame D is enlarged and rotated to obtain Figure 7 . Figure 9 . Figure 10 is a structure diagram of the sorting line blocking part in the embodiment of the application.

[0100] As shown in Figure 1 , Figure 7 , Figure 9 and Figure 10 , one end of the goods sorting line 29i is connected to the sorting annular rail 23, and the other end is connected to the receiving annular rail 24 of the second-stage sorting equipment 103. The goods sorting line 29i is also provided with a sorting line blocking part 40 at the end close to the receiving annular rail 24, for blocking or releasing the hangers 200 at this position.

[0101] The sorting line blocking part 40 has a blocking rod 401 and a blocking rod drive cylinder 402 connected to the blocking rod 401, and the blocking rod 401 can be turned by the driving of the blocking rod drive cylinder 402. When the blocking rod 401 is turned to the position shown in Figure 9 and Figure 10 , the blocking rod 401 blocks the hangers 200 at one end of the goods sorting line 29i, and when the blocking rod 401 is turned in the direction indicated by the arrow D5 in Figure 10 , the blocking rod 401 releases the hangers 200 at one end of the goods sorting line 29i, and the hangers 200 move in the direction indicated by the arrow D6 in Figure 9 , enter the transfer rail 41 after being guided and turned by the curved guide transfer member 73, and move in the direction indicated by the arrow D7 in Figure 9 , the transfer rail 41 is connected to the receiving annular rail 24, and the transfer rail 41 is inclined downward in the conveying direction, so that the hangers 200 can slide down through the transfer rail 41 and be hooked by the format member 222 on the receiving annular rail 24, so as to enter the receiving annular rail 24.

[0102] Figure 11 is a connection structure diagram of the sorting transfer mechanism and the goods sorting line in the second level sorting equipment in the embodiment of the present application.

[0103] As shown in Figure 11 , in the second level sorting equipment 103, the sorting transfer mechanism 107 includes a receiving ring track 24 composed of a format type conveying track, a sorting ring track 27 composed of a bird hook type conveying track, and a sorting connecting line 36 connecting the two ring tracks, and n goods sorting lines 291 are connected to the sorting ring track 27 in sequence.

[0104] As shown in Figure 7 and Figure 11 , the structure of the sorting transfer mechanism 107 is consistent with that of the sorting transfer mechanism 106, and the connection structure of the sorting transfer mechanism 107 and the n goods sorting lines 291 is also consistent with that of the sorting transfer mechanism 106 and the m goods sorting lines 291, that is, a sorting and splitting assembly 261 is arranged at the connection, and a sorting line blocking part 40 is also arranged on the goods sorting line 291, which will not be repeated here.

[0105] One end of the goods sorting line 291 is connected to the sorting ring track 27, and the other end is connected to the warehouse-out ring track 30.

[0106] Figure 12 is a structure diagram of the sorting blocking part in the embodiment of the present application.

[0107] As shown in Figure 12 , the sorting ring track 27 also has a sorting entry blocking part 271, which is embedded and arranged at an upstream position of the connection between the sorting ring track 27 and the sorting connecting line 36, that is, at the position shown in B2 of Figure 12 , for blocking the hanger 200 that does not enter the goods sorting line 291, so that the hanger 200 is temporarily stored at this position. Specifically, the sorting entry blocking part 271 includes a movable blocking block 2711 arranged in a groove on the sorting ring track 27 and a driving cylinder 2712, which can drive the movable blocking block 2711 to move up and down, thereby realizing the blocking or release of the hanger 200.

[0108] The same position on the sorting ring track 23 is also provided with a sorting entry blocking part 271, that is, at the position shown in B3 of Figure 7 , which will not be repeated here.

[0109] Figure 13 is a distribution position diagram of the splitting carrier reader in the embodiment of the present application.

[0110] As shown in Figure 13As shown in (a), in the first-level sorting equipment 102, m diversion carrier readers 313i are respectively located upstream of and close to the corresponding sorting and diversion components 26i, and are used to read the carrier identification codes of the hangers 200 passing through that location. Where 1≤i≤m, m=30.

[0111] like Figure 13 As shown in (b), in the second-level sorting equipment 103, n diversion carrier readers 313i are respectively located upstream of and close to the corresponding sorting and diversion components 26i, and are used to read the carrier identification codes of the hangers 200 passing through that location. Where m+1≤i≤m+n, m=30, n=20.

[0112] In this embodiment, the sorting carrier reader 313i is an RFID reader, which is fixedly installed on the side of the sorting ring track 23 or sorting ring track 27 by a bracket. Its height position corresponds to the position of the hanger 200 when it passes through the sorting ring track 23 or sorting ring track 27. Therefore, it can read the RFID tag on the hanger 200 when it passes through, and does not hinder the movement of the hanger 200 on the sorting ring track 23 or sorting ring track 27.

[0113] The sorting control unit 301 controls the operation of various components related to sorting in the control device 300, including: controlling the sorting transfer mechanism 106 to remove each hanger 200 from the goods sorting line 29 and transfer it to the sorting circular track 27 based on goods identification information and predetermined goods removal rules; assigning each hanger 200 to the goods sorting line 29 based on goods identification information and predetermined goods sorting rules; controlling the sorting diversion component 26i to connect the corresponding goods sorting line 29 to the sorting circular track 27 based on the carrier identification code; and controlling the sorting transfer mechanism 106 to transfer the hanger 200 to the corresponding goods sorting line 29.

[0114] The sorting control unit 301 also stores predetermined goods retrieval rules and goods sorting rules. In this embodiment, the goods retrieval rule is to retrieve all garments on one or more goods sorting lines 29i with the same first-level sorting attribute to the receiving circular track; the goods sorting rule is to sort garments with sorting attributes in the attribute information to the same goods sorting line 29i or several consecutive goods sorting lines 29i.

[0115] Specifically, the sorting control unit 301 includes a sorting and allocation unit 3011, an attribute acquisition unit 3012, a sorting determination unit 3013, and a diversion control unit 3014.

[0116] The sorting allocation unit 3011 is used to allocate a corresponding goods sorting line for each sorting attribute, and the sorting allocation unit 3011 comprises a quantity counting part 30111, a sorting line calculation part 30112 and a sorting line setting part 30113.

[0117] The quantity counting part 30111 is used to count the total quantity of goods corresponding to each sorting attribute in the same batch of goods, for example, the sorting attributes are the colors of the goods, “white” and “black”, and the quantity counting part 30111 counts that there are 10 pieces of white clothes and 40 pieces of black clothes.

[0118] The sorting line calculation part 30112 is used to calculate the number of goods sorting lines 29 required for each sorting attribute based on the total quantity corresponding to each attribute obtained by the quantity counting part, for example, there are 10 pieces of white clothes, and the calculation result of the sorting line calculation part 30112 shows that one goods sorting line 29i is required for the first-level sorting attribute “white”, and there are 40 pieces of black clothes, and the calculation result of the sorting line calculation part 30112 shows that four goods sorting lines 29i are required for the first-level sorting attribute “black”.

[0119] The sorting line setting part 30113 is used to set a corresponding number of goods sorting lines 29i for each sorting attribute based on the number of goods sorting lines 29i obtained by the sorting line calculation part, for example, based on the calculation result of the sorting line calculation part, one goods sorting line 29i is allocated for the first-level sorting attribute “white”, and goods sorting lines 292 to 295 are allocated for the first-level sorting attribute “black”.

[0120] The attribute acquisition unit 3012 acquires the attribute information of the clothes on the clothes hanger 200 by searching the information storage unit 302 according to the carrier identification code read by the carrier reader 313i.

[0121] The sorting control unit 3014 controls the sorting shunting assembly 26i to connect or disconnect the sorting ring track 27 and the goods sorting line 29i according to the determination result of the sorting determination unit 3013, so as to complete the sorting of the clothes hanger 200, for example, according to the determination result of the sorting determination unit 3013, the clothes hanger 200 hanging the white clothes should enter the current goods sorting line 29i, and the sorting control unit 3014 controls the corresponding sorting shunting assembly 26i to connect the sorting ring track 23 and the current goods sorting line 29i, so as to make the clothes hanger 200 enter the current goods sorting line 29i.

[0122] Figure 14 is the work flow chart of the two-level sorting of goods in the embodiment of the present application.

[0123] As Figure 14As shown, in the present embodiment, the work flow of two-stage sorting of the hangers 200 on which the garments to be sorted are placed includes the following steps:

[0124] Step S1-1:

[0125] The operator inputs the total number c of hangers 200 to be sorted and a first-stage sorting attribute via the terminal. Then, step S1-2 is entered.

[0126] Step S1-2:

[0127] The sorting control unit 301 sets a corresponding goods sorting line 29i for each first-stage sorting attribute based on the total number c. Then, step S1-3 is entered.

[0128] Step S1-3:

[0129] The operator starts the receiving loop 22 and the sorting loop 23 via the terminal, i.e., starts the corresponding receiving drive unit and the sorting drive unit via the sorting control unit 301. Then, step S1-3a is entered.

[0130] Step S1-3a:

[0131] k is set to 1, i.e., the first hanger 200 is designated. Then, step S1-4 is entered.

[0132] Step S1-4:

[0133] The operator hangs the kth hanger 200 on the upper line section 211 of the goods rack line 21, and the hanger 200 is then loaded onto the rack, and the first-stage sorting is started. Then, step S1-5 is entered.

[0134] Step S1-5:

[0135] It is determined whether k is equal to c, i.e., whether all hangers 200 have been loaded onto the rack. When the determination is negative, step S1-5a is entered; when the determination is positive, step S1-6 is entered.

[0136] Step S1-5a:

[0137] k is set to k+1, i.e., the next hanger 200 is designated. Then, step S1-4 is returned to.

[0138] Step S1-6:

[0139] It is determined whether the first-stage sorting is completed, i.e., whether all hangers 200 have entered the goods sorting line 29i or reached the sorting entry stop 271. When the determination is negative, step S1-6 is repeated; when the determination is positive, step S1-7 is entered.

[0140] Step S1-7:

[0141] The operator inputs the total number d of the hangers 200 to be sorted and the b second-level sorting attributes via the terminal. Then, the process proceeds to step S1-7a. The total number d is the total number c minus the number of hangers 200 that are not successfully sorted and are temporarily stored at the sorting entry block 271.

[0142] Step S1-8:

[0143] The sorting control section 301 sets the corresponding goods sorting line 29i for each second-level sorting attribute based on the total number d. Then, the process proceeds to step S1-9.

[0144] Step S1-9:

[0145] The operator starts the receiving loop 24 and the sorting loop 27 via the terminal, i.e., starts the corresponding receiving drive section and the sorting drive section via the sorting control section 301. Then, the process proceeds to step S1-9a.

[0146] Step S1-9a:

[0147] The value of k is set to 1, i.e., the first second-level sorting attribute is designated. Then, the process proceeds to step S1-10.

[0148] Step S1-10:

[0149] The sorting control section 301 controls the sorting transfer mechanism 107 to take out all the hangers 200 corresponding to the garments having the kth first-level sorting attribute from the goods sorting line 29i of the first-level sorting device 102. The hangers 200 are taken out and the second-level sorting is started. Then, the process proceeds to step S1-11.

[0150] Step S1-11:

[0151] It is determined whether the hangers 200 corresponding to the kth first-level sorting attribute have all completed the second-level sorting, i.e., whether all the taken-out hangers 200 have entered the goods sorting line 29i of the second-level sorting device 103 or reached the sorting entry block 271 of the sorting loop 27. Then, the process proceeds to step S1-12.

[0152] Step S1-12:

[0153] It is determined whether k is equal to a, i.e., whether the taking-out and the second-level sorting have been completed for all the first-level sorting attributes. When the determination is negative, the process proceeds to step S1-12a; when the determination is positive, the two-level sorting of all the hangers 200 is completed.

[0154] Step S1-12a:

[0155] The value of k is set to k+1, i.e., the next first-level sorting attribute is designated. Then, the process returns to step S1-8.

[0156] Figure 15 is a work flow chart of the first level sorting of the goods in the embodiment of the present application.

[0157] As shown in Figure 15 , after each hanger 200 is put on the hanger putting line 21, the work flow of the first level sorting of the hanger 200 includes the following steps:

[0158] Step S2-1:

[0159] The hanger 200 enters the receiving loop 22, and the receiving driving part drives the hanger 200 to move along the receiving loop 22. Then it enters step S2-2.

[0160] Step S2-2:

[0161] The hanger 200 reaches the connection between the receiving loop 22 and the sorting connecting line 35, leaves the receiving loop 22 through the off-track member 711, and enters the sorting loop 23 through the sorting connecting line 35. Then it enters step S2-3.

[0162] Step S2-3:

[0163] The sorting driving part drives the hanger 200 to move along the sorting loop 23. Then it enters step S2-3a.

[0164] Step S2-3a:

[0165] Set k = 1, i.e. designate the first sorting carrier reader 3131. Then it enters step S2-4.

[0166] Step S2-4:

[0167] The receiving driving part drives the hanger 200 to move to the position of the sorting carrier reader 313k. Then it enters step S2-5.

[0168] Step S2-5:

[0169] The sorting carrier reader 313k reads the carrier identification code of the hanger 200. Then it enters step S2-6.

[0170] Step S2-6:

[0171] The attribute acquisition unit 3012 searches the information storage part 302 to acquire the attribute information of the clothes corresponding to the hanger 200. Then it enters step S2-7.

[0172] Step S2-7:

[0173] The sorting determination unit 3013 determines whether the garment hanger 200 should enter the goods sorting line 29k according to the first-level sorting attribute and the obtained attribute information, and when the determination result is no, step S2-8 is entered; when the determination result is yes, step S2-10 is entered.

[0174] Step S2-8: Determine whether k is equal to m, i.e., whether the current shunting carrier reader 313k is the last shunting carrier reader 313m in the first-level sorting device 102, and when the determination result is no, step S2-8a is entered; when the determination result is yes, step S2-10 is entered.

[0175] Step S2-8a:

[0176] Set k=k+1, i.e., specify the next shunting carrier reader 313k. Then return to step S2-4.

[0177] Step S2-9:

[0178] The sorting driving part drives the garment hanger 200 to move to the sorting blocking part 271 for temporary storage.

[0179] Step S2-10:

[0180] The sorting shunting assembly 26k is controlled by the sorting control unit 3014 to communicate the goods sorting line 29k with the sorting ring track 23. Then step S2-11 is entered.

[0181] Step S2-11:

[0182] The sorting driving part drives the garment hanger 200 to move to the sorting shunting assembly 26k, and the garment hanger 200 enters the communicated goods sorting line 29k, and the first-level sorting is completed.

[0183] In the above process, if the garment hanger 200 does not enter any goods sorting line 29i, it will continue to move under the driving of the sorting driving part until it is blocked at the sorting entry blocking part 271. After the operator observes that the garment is stalled, the garment hangers 200 that have not successfully sorted on the sorting ring track 22 and the sorting ring track 27 can be collected and reprocessed.

[0184] Figure 16 is a work flow chart for taking out the goods to be sorted from the first-level sorting device in the embodiment of the application.

[0185] As shown in Figure 16 , for each first-level sorting attribute, the work flow for taking out all garment hangers 200 includes the following steps:

[0186] Step S3-1:

[0187] The storage control unit 301 acquires the goods sorting line 29a to the goods sorting line 29b corresponding to a first sorting attribute, that is, all the hangers 200 on the goods sorting line 29a to the goods sorting line 29b are to be taken out. Then, step S3-1a is entered.

[0188] Step S3-1a:

[0189] Set k=a, that is, the goods sorting line 29a is designated. Then, step S3-2 is entered.

[0190] Step S3-2:

[0191] The storage control unit 301 controls the sorting line blocking unit 40 on the goods sorting line 29k to release the hangers 200. Then, step S3-3 is entered.

[0192] Step S3-3:

[0193] It is judged whether the hangers 200 on the goods sorting line 29k have all left the goods sorting line 29k, which can be specifically that the storage control unit 301 waits for a predetermined time according to previous data. Then, step S3-4 is entered.

[0194] Step S3-4:

[0195] It is judged whether k is equal to b, that is, whether the current goods sorting line 29k is the last goods sorting line 29b to be taken out. When the judgment is no, step S3-4a is entered, and when the judgment is yes, the taking out of the first sorting attribute is completed.

[0196] Step S3-4a:

[0197] Set k=k+1, that is, the next goods sorting line 29k is designated. Then, step S3-2 is returned.

[0198] The hangers 200 are taken out from the first sorting device 102 and then start the second sorting. The work flow of the second sorting is the same as that of the first sorting, and will not be repeated.

[0199] <Embodiment Two>

[0200] The embodiment provides a fixed-shelf-free sorting system 100.

[0201] In the embodiment one, the hangers 200 that are not successfully sorted are blocked by the blocking unit 271 and stay on the sorting ring track 22 or the sorting ring track 27. After the operators observe this phenomenon, the hangers 200 can be collected and re-shelved.

[0202] Figure 17 is a structural schematic diagram of a fixed-shelf-free sorting system in the embodiment of the application.

[0203] As Figure 1 and Figure 17 In this embodiment, compared with the first embodiment, the sorting transfer mechanism 107 further has a sorting return track 1071, and the delivery transfer mechanism 108 further has a first return track 1081 and a second return track 1082.

[0204] The sorting return track 1071 is connected between the sorting ring track 27 and the receiving ring track 22, and is used to transport the hangers 200 that are not successfully sorted on the sorting ring track 27 back to the receiving ring track 22, i.e., transport the hangers 200 back to the previous level of equipment, so that the hangers 200 can be re-sorted, or re-sorted after setting different sorting attributes.

[0205] The sorting return track 1071 has the same structure as the sorting ring track 23, i.e., a bird hook type conveying track. The load track 63 at the end of the sorting return track 1071 close to the receiving ring track 22 is connected with a bending guide connecting member 73, so that the hangers 200 reaching this position can be guided to turn and fall onto the format member 222 of the receiving ring track 22, which will not be described in detail here.

[0206] The first return track 1081 is connected between the delivery ring track 30 and the sorting ring track 28, and the second return track 1082 is connected between the delivery ring track 30 and the receiving ring track 22, and has the same structure and working principle as the sorting return track 1071, which will not be described in detail here.

[0207] <Embodiment Three>

[0208] This embodiment provides a fixed-shelf-free sorting system 100.

[0209] In the first embodiment, the reading unit 310 has m+n sorting flow carrier readers 313i, which are respectively arranged at the upstream positions of each sorting flow assembly 26i of the sorting ring track 23 and the sorting ring track 27, and are used to read the carrier identification code of the passing hangers 200.

[0210] Figure 18 is a structural block diagram of the fixed-shelf-free sorting system in the embodiment of the application.

[0211] Figure 19 is a distribution position diagram of the sorting flow carrier reader and the moving speed obtainer in the embodiment of the application.

[0212] As Figure 18 and Figure 19As shown, compared with the first embodiment, in the present embodiment, the reading unit 310 has two split carriers readers 3131, 3132, which are respectively arranged at the upstream position of the sorting split assembly 261, 26m+1 at the most upstream of the sorting ring track 23 and the sorting ring track 27; at the same time, in the present embodiment, the control device 300 also has two moving speed acquirers 3141, 3142, which are respectively used to acquire the moving speed of the hanger 200 on the sorting ring track 23 and the sorting ring track 27.

[0213] The structures of the moving speed acquirers 3141 and 3142 are consistent, and the moving speed acquirer 3141 is taken as an example for specific description.

[0214] The moving speed acquirer 3141 comprises a photoelectric sensing part and a speed calculation part. The photoelectric sensing part is arranged on the sorting ring track 23 and is used to sense the passing bird hook conveying unit 61. The speed calculation part calculates the moving speed according to the number of the passing bird hook conveying units 61 in a unit time and the interval of the adjacent bird hook conveying units 61. In the present embodiment, since the bird hook conveying units 61 are adjacent to each other, the interval of the adjacent bird hook conveying units 61 is equal to the length of the bird hook conveying unit 61.

[0215] The sorting control unit 301 acquires the corresponding goods identification information based on the read carrier identification code, determines the goods sorting line 29i that the hanger 200 should enter according to the predetermined goods sorting rule, judges the arrival time of the hanger 200 to the goods sorting line 29i that should be entered according to the above-mentioned moving speed, and further controls the sorting split assembly 26i to communicate the corresponding goods sorting line 29i with the sorting ring track 27 based on the arrival time, so as to guide the hanger 200 into the goods sorting line 29i.

[0216] Figure 20 is the working flow chart of the goods in the first level sorting in the embodiment of the present application.

[0217] As shown in the present embodiment, the working flow of the hanger 200 in the first level sorting includes steps S4-1 to S4-11, which basically correspond to the steps S2-1 to S2-10 in the first embodiment except for the above-mentioned description, and thus the description is not repeated. Figure 20

[0225] In the first-stage sorting device 102, one of the storage location readers is arranged at the flow-off carrier reader 313i as a binding storage location reader 3151, and m storage location readers are arranged at the upstream position of the m sorting flow-off assemblies 26i as m flow-off storage location readers 316i.

[0226] When the hanger 200 passes the binding storage location reader 3151, the binding storage location reader 3151 reads the storage location identification code of the bird-hook conveying unit 61 corresponding to the hanger 200, and the sorting control part 301 controls the information storage part 302 to store the storage location identification code of the bird-hook conveying unit 61, the carrier identification code of the hanger 200 and the goods identification information of the clothes correspondingly, so as to realize the binding of the three.

[0227] Subsequently, the sorting control part 301 determines the goods sorting line 29i that the hanger 200 should enter based on the predetermined goods sorting rule, and controls the sorting flow-off assembly 26i to communicate the corresponding goods sorting line 29i with the sorting ring track 23 based on the storage location identification code read by the flow-off storage location reader 316i, so as to guide the hanger 200 into the corresponding goods sorting line 29i.

[0228] In the second-stage sorting device 103, the flow-off carrier reader and the storage location reader are arranged in the same way as in the first-stage sorting device 102, and will not be repeated.

[0229] Figure 23 is a work flow chart of the first level sorting of goods in the embodiment of the present application.

[0230] As shown in Figure 23 , the work flow of the first level sorting of the hanger 200 in the embodiment includes: from the starting state step S5-1, S5-2 to step S5-14, to the ending state, the sorting action flow is the same as Figure 15 the sorting action flow in the first embodiment in the embodiment one, that is, the steps S5-1 to S5-3 in the embodiment are the same as the steps S2-1 to S2-3 in the embodiment one, the steps S5-4 to S5-6 in the embodiment are the binding steps of the hanger 200, the clothes and the bird hook seat as described above, the steps S5-7 to S5-14 in the embodiment are the same as the steps S2-4 to S2-11 in the embodiment one, therefore the same steps are not repeated.

[0231] The work flow of the second level sorting of the hanger 200 is the same as the work flow of the first level sorting, and is not repeated.

[0232] <Embodiment Five>

[0233] The embodiment provides a fixed goods rack sorting system 100.

[0235] Figure 25 is a distribution position schematic diagram of the sorting line full load sensor in the embodiment of the present application.

[0236] As shown in Figure 2 , Figure 24 and Figure 25 , compared with the embodiment one, in the embodiment, the control device 300 further has a sensing part 320, the sensing part 320 has m+n sorting line full load sensors 325i, wherein 1≤i≤m+n.

[0237] In the first level sorting device 102, the m sorting line full load sensors 325i are respectively arranged at the end of the m goods sorting lines 29i close to the sorting annular track 23.

[0238] In the second level sorting device 103, the n sorting line full load sensors 325i are respectively arranged at the end of the n goods sorting lines 29i close to the sorting annular track 27.

[0239] The sorting line full load sensor 325i is used to sense the hangers 200. In this embodiment, the sorting line full load sensor 325i is a photoelectric sensing unit, which is embedded in the track section of the goods sorting line 29i. Once the number of hangers 200 carried on the goods sorting line 29i is too large, the upstream hangers 200 reach the position where the sorting line full load sensor 325i is located, and the sorting line full load sensor 325i generates a corresponding full load signal.

[0240] When the sorting control unit 301 senses the hangers 200 through the sorting line full load sensor 323, it controls the corresponding sorting flow assembly 26i to disconnect the corresponding goods sorting line 29i from the sorting ring track 23 or the sorting ring track 27, so that the hangers 200 no longer enter the goods sorting line 29i.

[0241] Figure 26 is the work flow chart of the first level sorting of the goods in this embodiment of the application.

[0242] As shown in Figure 26 , the work flow of the first level sorting of the hangers 200 in this embodiment includes steps S6-1, S6-2 to S6-13 from the start state to the end state, and the sorting action flow is the same as that of Figure 15 some steps in the sorting action flow of the first embodiment in . The steps S6-1 to S6-9 in this embodiment are the same as the steps S2-1 to S2-9 in the first embodiment, the steps S6-11 and S6-12 in this embodiment are the same as the steps S2-10 and S2-11 in the first embodiment, and the step S6-10 in this embodiment is the judgment step of whether the sorting line full load sensor 325i senses the hangers 200 or not, so the same steps will not be repeated.

[0243] The work flow of the second level sorting of the hangers 200 is the same as that of the first level sorting, and will not be repeated.

The first-level sorting device 102 is provided with a sorting transfer mechanism 106 and m goods sorting lines 29i. The second-level sorting device 103 is provided with a sorting transfer mechanism 107 and n goods sorting lines 29i. Therefore, the garment rack 200 loaded with garments can be shelved, and the garment rack 200 can be classified and sorted according to the first-level sorting attribute, the second-level sorting attribute and the predetermined goods sorting rule, and then be transferred to the corresponding goods sorting line 29i. Further, the control device 300 is provided with a sorting control part 301 and an information storage part 302. The information storage part 302 stores the goods identification information, the attribute information of the garments and the carrier identification code of the corresponding garment rack 200. Therefore, the sorting control part 301 can assign the corresponding goods sorting line 29i to each garment rack 200 based on the sorting attribute and the attribute information, and control the sorting transfer mechanism 106, 107 to distribute the garment rack 200 to each goods sorting line 29i according to the sorting attribute of each level, so as to realize the rapid two-level sorting of the garments. The whole sorting process is efficient and highly automated. Further, the fixed-shelf-free sorting system 100 of the present application adopts a track form for conveying and storing, so that it is not necessary to set up fixed shelves, nor to be equipped with conveying equipment such as stacker cranes and shuttles, and it is easy to build and low in cost.

[0246] Specifically, the transfer mechanism 106 for sorting has the receiving ring track 22, the sorting ring track 23, the sorting connecting line 35, and m sorting shunting assemblies 26i capable of connecting or disconnecting each goods sorting line 29i with the sorting ring track 23; meanwhile, the control device 300 also has the reading part 310 with m shunting carrier readers 313i respectively arranged at the upstream position of the corresponding sorting shunting assembly 26i, the sorting control part 301 has the sorting distribution unit 3011, the attribute acquisition unit 3012, the sorting determination unit 3013, and the shunting control unit 3014, so that when the garment hanger 200 moves to the position of the shunting carrier reader 313i on the sorting ring track 23, the shunting carrier reader 313i can read the carrier identification code of the garment hanger 200, the attribute acquisition unit 3012 can acquire the attribute information of the corresponding garment according to the read carrier identification code, the sorting determination unit 3013 can determine the goods sorting line 29i that the garment hanger 200 should enter according to the acquired attribute information, and the shunting control unit 3014 can control the corresponding sorting shunting assembly 26i to connect the goods sorting line 29i that should be entered with the sorting ring track 23, so as to make the garment hanger 200 enter the goods sorting line 29i that should be entered. Therefore, the control device 300 and the first-level sorting equipment 102 of the first embodiment can automatically classify and sort the garment hangers 200 based on the attribute information of the garments and the carrier identification codes of the corresponding garment hangers 200. Since there is also the second-level sorting equipment 103 which has the same structure as the first-level sorting equipment 102, the garment hangers 200 can be automatically classified and sorted in two levels.

[0247] In the second embodiment, the transfer mechanism 107 for sorting also has the sorting return track 1071, and the transfer mechanism 108 for delivery also has the first-level return track 1081 and the second-level return track 1082, so that the garment hangers 200 that are not successfully sorted in the second-level sorting equipment 103 can return to the first-level sorting equipment 102 through the sorting return track 1071, the garment hangers 200 that are sorted incorrectly in the delivery equipment 104 can return to the second-level sorting equipment 103 through the first-level return track 1081, and can return to the first-level sorting equipment 102 through the second-level return track 1082, so as to make the garment hangers 200 that are not successfully sorted or incorrectly sorted automatically return to the upper-level equipment for re-classification and sorting, or re-classification and sorting after setting different sorting attributes, further reducing the need for manual intervention and improving the degree of automation.

[0248] In the third embodiment, the reading unit 310 has two shunting carriers readers 3131, 3132 and two moving speed acquirers 3141, 3142, which are respectively arranged in the two sorting devices 102, 103, so that the moving speed of the clothes hanger 200 on the sorting ring track 23, 27 can be acquired respectively, the arrival time of the clothes hanger 200 to the goods sorting line 29i that should be entered is calculated according to the moving speed, and the sorting shunting assembly 26i is further controlled to be connected to the corresponding goods sorting line 29i according to the arrival time. The second embodiment realizes the same function, and the reading unit 310 only has four readers, so that the structure is simpler and the cost is lower, and the control mode based on the moving speed also makes the sorting process very smooth.

[0249] In the fourth embodiment, the reading unit 310 has two shunting carriers readers 3131, 3132 and m+n+2 position readers, two of which are binding position readers 3151, 3152, and the rest are shunting position readers 316i, which are respectively arranged at the upstream position of the corresponding sorting shunting assembly 26i, so that the position identification code of the passing bird hook seat can be read, the corresponding bird hook seat, clothes hanger 200 and clothes are bound, and the sorting process is controlled based on the position identification code. During the movement of the clothes hanger 200 on the track, the movement speed, environmental factors and other factors may cause the clothes hanger 200 to shake, which has a certain influence on the reading of the carrier identification code. The bird hook seat moves through the pulley set embedded in the track, which is relatively more stable, so that the control mode based on the position identification code has higher accuracy and smaller probability of sorting error, and accordingly the need for manual intervention is reduced.

[0250] In the fifth embodiment, the control device 300 further has a sensing unit 320, which has m+n sorting line full load sensors 325, which are respectively arranged at the end of each goods sorting line 29i close to the next level device, so that the sorting control unit 301 can receive the corresponding full load signal when the goods sorting line 29i is full, and control the corresponding sorting shunting assembly 26i to disconnect the connection between the goods sorting line 29i and the sorting ring track, so as to avoid too many clothes hangers 200 stacked on the goods sorting line 29i, which affects the subsequent further sorting or warehouse out. Therefore, the reliability of the system is further improved.

[0251] The above embodiments are only used to illustrate the specific embodiments of the present application, and the present application is not limited to the description range of the above embodiments.

[0252] In the above embodiments, the number of sorting devices is two, and in actual application, one or more sorting devices can be arranged according to actual needs to realize single-stage or multi-stage classification and sorting.
