Description

Technical Field

[0001] The present invention belongs to the field of cargo warehousing, and in particular relates to a batch-type storage and sorting system without fixed shelves. Background Art

[0002] In the prior art, cargo storage typically involves manually placing goods into containers, sorting and labeling the containers, and then placing them on different shelves according to the labels. Conveyors are then used to transport goods between different storage facilities. In these cargo storage systems, the shelves are cumbersome to set up and require a large amount of floor space. Sorting and moving the containers requires significant manpower, and the conveyor equipment also requires operating space. Consequently, these systems present challenges such as cumbersome shelf setup, large floor space occupied by the shelves and conveyor equipment, and high costs.

[0003] Furthermore, when such a cargo storage system is applied to industries where goods are in the form of soft sheets, such as the clothing industry, multiple pieces of clothing need to be packed into the same container during the warehousing process. This not only requires manpower and material resources, but also causes the clothes to be stacked and squeezed, resulting in wrinkles. Furthermore, in the clothing industry, goods are often stored according to production batches and sorted, packed, and shipped out according to clothing attributes. Clothes from the same production batch are often large in number, and clothing has multiple attributes, such as size, color, style, etc., so the actual sorting and shipping requirements are relatively complex. Manual packaging and sorting for warehousing and shipping out will be very time-consuming, inefficient, and prone to classification errors. Because multiple pieces of clothing are packed into the same container, any classification error requires manual unpacking, inspection, and repacking, which is very inconvenient.

[0004] To this end, a batch-type non-fixed shelf storage and sorting system has become an urgent need in the current clothing warehousing industry. It does not require the construction of fixed shelves, can keep clothing flat, can quickly store large quantities of goods according to the production batches of the goods, and can automatically sort according to the sorting attributes of the goods.

[0063] The delivery transfer mechanism 108 includes a sorting and outputting circular track 28, a delivery circular track 30, and a delivery connecting line 37. A plurality of cargo delivery lines 31 are connected to the delivery circular track 30, and the delivery connecting line 37 connects the sorting and outputting circular track 28 and the delivery circular track 30.

[0064] Both ends of the cargo storage line 25i are connected to the storage entry circular track 23 and the storage output circular track 24 respectively; both ends of the cargo sorting line 29j are connected to the sorting entry circular track 27 and the sorting output circular track 28 respectively.

[0065] from Figure 1 It can be directly seen that the circular track 22 for warehousing, the circular track 23 for storage entry and the circular track 27 for sorting entry in this embodiment are all closed circular tracks, while the cargo storage line 25i and the cargo sorting line 29j are linear tracks.

[0066] In addition, in this embodiment, the number of cargo loading lines 21 is 2, the number of cargo storage lines 25i is 100, that is, m=100, and the number of cargo sorting lines 29j is 30, that is, n=30. The figure uses an abbreviated drawing method to show only part of them.

[0067] like Figure 2 As shown in , the batch-type non-fixed shelf storage and sorting system 100 of this embodiment further includes a control device 30 for controlling the process of goods entering, sorting and leaving the warehouse.

[0074] Table 1 Cargo information storage table

[0075]

[0076] Figure 3 2 is a schematic structural diagram of a cargo loading line in an embodiment of the present invention.

[0077] like Figure 3 As shown, the cargo carrier of this embodiment is a clothes hanger 200, which includes a hook 201 and a support portion (not shown) for carrying clothes. The specific structure adopts a conventional structure in the prior art. The hook 201 has a hanging opening 201a, through which the hook 201 is hung on each conveyor track.

[0078] The cargo loading line 21 includes an upper line segment 211 , an upper line buffer segment 212 , an ascending segment 213 , an upper line driving unit 333 and an upper line blocking unit 332 .

[0079] The upper line segment 211 is used to receive the hangers 200 to be stored. The upper line segment 211 is located at a relatively low position, which makes it convenient for the operator to hang the hangers 200 on the upper line segment 211. The upper line segment 211 extends downward along the conveying direction of the hangers 200. Therefore, after the hanger 200 is hung on one end of the upper line segment 211, it can rely on gravity to slide to the connection between the upper line segment 211 and the rising segment 213.

[0080] The upper line buffer section 212 is used to guide the hanger 200 received by the upper line section 211 into the circular track 22 for warehousing. The upper line buffer section 212 is located at a relatively high place, and the end of the upper line buffer section 212 close to the circular track 22 for warehousing is at the same height as the circular track 22 for warehousing. The upper line buffer section 212 also extends downward along the conveying direction of the hanger 200, so after the hanger 200 reaches the upper line buffer section 212, it can rely on gravity to slide and enter the circular track 22 for warehousing.

[0081] 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 to the upper line buffer section 212 along the rising section 213. The rising section 213 extends upwardly and obliquely along the conveying direction.

[0082] The upper line driving unit 333 is used to drive the hanger 200 that reaches the connection between the upper line segment 211 and the ascending segment 213 to move along the ascending segment 213 to the upper line buffer segment 212. In this embodiment, the upper line driving unit 333 is a hoist provided on the ascending segment 213.

[0083] The carrier identification code reader 311 is set at the starting position of the upper line segment 211 of the cargo loading line 21, that is, Figure 3 At position B1, a carrier identification code reader 311 is used to read the carrier identification code of the hanger 200 to obtain the carrier identification code. In this embodiment, the hanger 200 is provided with an RFID tag containing the carrier identification code; the carrier identification code reader 311 is a handheld RFID reader that an operator can hold to read the RFID tag and obtain the carrier identification code.

[0084] The cargo identification information reader 312 is set at the starting position of the upper line segment 211 of the cargo loading line 21, and is set at approximately the same position as the carrier identification code reader 311, that is, Figure 3At position B1, the cargo identification information reader 312 is used to read the identification information of the clothing on the hanger 200 to obtain the cargo identification information of the clothing. In this embodiment, the clothing is provided with a label containing a QR code that corresponds one-to-one with the cargo identification information (i.e., the identification code) of the clothing. The cargo identification information reader 312 is a handheld barcode scanner that an operator can use to read the clothing label to obtain the corresponding cargo identification information.

[0085] After the carrier identification code reader 311 reads the carrier identification code and the cargo identification information reader 312 reads the cargo identification information, the operator inputs the carrier identification code and the cargo identification information one by one through the operation terminal, and the warehousing control unit 301 controls the information storage unit 34 to store the carrier identification code of the hanger 200 and the cargo identification information of the clothing in correspondence to realize the binding of the clothing and the hanger 200.

[0086] Figure 4 It is a structural diagram of the transfer mechanism for warehousing in an embodiment of the present invention.

[0087] like Figure 4 As shown, the storage transfer mechanism 106 includes a storage circular track 22 , a cargo storage entry circular track 23 , and a storage connection line 35 .

[0088] Figure 5 yes Figure 4 Enlarged view of the portion within frame A.

[0089] like Figure 5 As shown, the circular track 22 for warehousing 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. In this embodiment, the random conveying type conveying track is a format type conveying track, which includes a plurality of format components 222. The format component 222 is used to carry and transport the hanger 200. The lower part thereof is in a "G" shape that matches the hook of the hanger 200, and the upper part thereof is a pulley (not shown in the figure) that can be accommodated in the track section of the carrying track 221 of the circular track 22 for warehousing. The format component 222 is moved along the circular track 22 for warehousing by a pulley group embedded in the circular track 22 for warehousing. Figure 5 Move in the direction indicated by the arrow D1.

[0090] The storage annular track 22 also has a storage driving unit (not shown) for driving the movement of each format member 222. The storage driving unit has a drive motor and a plurality of drive wheels, and the specific structure can adopt a conventional structure in the prior art. Figure 5 Only part of the format components 222 is shown in FIG. In fact, multiple format components 222 are arranged in accordance with Figure 5The format components 222 shown in FIG are arranged in the same manner on the entire closed ring-shaped carrying track 221.

[0091] The storage entry circular track 23 is also 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, a guide rail 62 and a carrying rail 63. Among them, the carrying rail 63 is used to carry the hanger 200, and its part close to the connecting line 35 is linear. The bird hook type conveying unit 61 is used to hook the hook 201 of the hanger 200 and transport the hanger 200. The bird hook type conveying unit 61 has a bird hook seat, and a bird hook that can hook the hook 201 is installed below the bird hook seat, and a pulley group (not shown in the figure) housed in the guide rail 62 of the storage entry circular track 23 is installed above the bird hook seat. The bird hook type conveying unit 61 is moved along the storage entry circular track 23 through the pulley group. Figure 5 Move in the direction indicated by the arrow D3.

[0092] The storage entry circular track 23 also has a storage entry drive unit (not shown in the figure), which is used to drive the movement of each bird hook type conveying unit 61. The entry drive unit has a drive motor and multiple drive wheels, and the specific structure can adopt the conventional structure in the existing technology.

[0093] The storage connection line 35 is provided between the storage circular track 22 and the storage entry circular track 23 to guide the hanger 200 to transfer from the storage circular track 22 to the storage entry circular track 23. The connection line 35 is a connecting portion including a connection track 72, a guide transfer member 712, and a turning guide connection member 73.

[0094] The connecting rail 72 has an upper end portion 721 and a lower end portion 722. The upper end portion 721 is connected to the guide transfer member 712, and the lower end portion 722 is connected to the turning guide connecting member 73. Figure 5 As shown in FIG, the upper end 721 is positioned higher than the lower end 722, causing the connecting track 72 to tilt downward in the conveying direction. Therefore, after the hanger 200 enters the connecting track 72, it can slide from the upper end 721 to the lower end 722 by gravity without the need for additional driving force. In this embodiment, based on the conveying requirement of 1.5 kg, the inclination angle of the connecting track 72 is set to 20°, ensuring a moderate sliding speed for the hanger 200, neither too slow to cause low conveying efficiency nor too fast to cause unstable conveying of the hanger 200.

[0095] Figure 6 yes Figure 5 Enlarged view of the portion inside frame C.

[0096] like Figure 5 and Figure 6 As shown, the upper end 721 of the connecting track 72 is connected to the guide transfer component 712, and is further connected to the derail component 711 on the circular track 22 for warehousing. The guide transfer component 712 has an introduction end 82 that gradually widens along the conveying direction, a first main guide section 81 with a certain curvature, and an output end 83 that matches the connecting track. The derail component 711 has a derail portion 85, and the derail portion 85 has an inclined surface, which is connected to the introduction end 82 of the guide transfer component 712. Therefore, when the hanger 200 on the circular track 22 for warehousing moves to the derail portion 85 along the format-type conveying track, it can be guided by the inclined surface to turn, thereby leaving the circular track 22 for warehousing. Subsequently, the hanger 200 is guided to turn via the first main guide section 81 of the guide transfer component 712, and then transferred to the connecting track 72, along Figure 7 The direction indicated by the middle arrow D2 moves on the connecting track 72 .

[0097] The lower end 722 of the connecting track 72 is connected to the supporting track 63 of the storage access circular track 23 via a turning guide connecting member 73. The turning guide connecting member 73 has two connecting ends and a second main guide section with a certain curvature. The two connecting ends match the connecting track 72. The supporting track 63 has the same structure as the connecting track 72, so the two connecting ends also match the supporting track 63.

[0098] After the hanger 200 slides to the next end 722, it is guided by the turning guide connecting member 73 and transferred to the carrying track 63. It is further hooked by the bird hook conveying unit 61 on the guide rail 62 and driven by the bird hook conveying unit 61 to move along the storage entry ring track 23. Figure 5 Move in the direction indicated by arrow D3.

[0099] Figure 7 1 is a diagram showing the connection structure between the warehousing transfer mechanism and the cargo storage line in an embodiment of the present invention.

[0100] like Figure 7 As shown, one end of a plurality of cargo storage lines 25i is sequentially connected to the storage entry circular track 23, and the storage Figure 7 The direction indicated by the middle arrow D5, i.e., the conveying direction of the hanger 200, is used to sequentially record the plurality of cargo storage lines 25i as cargo storage line 251, cargo storage line 252, ..., cargo storage line 25i, ..., cargo storage line 25m. In this embodiment, m=100.

[0101] Figure 8 yes Figure 7 Enlarged view of the portion within frame B.

[0102] like Figure 8As shown, the warehousing transfer mechanism 106 also includes m distribution components 26i, which are respectively arranged at the connection between the storage entry circular track 23 and each cargo storage line 25i, and can connect or disconnect the storage entry circular track 23 and the corresponding cargo storage line 25i.

[0103] The distribution assembly 26i includes a connecting track segment 341, a telescopic track segment 342 and a telescopic drive member (not shown in the figure).

[0104] The telescopic track section 342 is arranged on the rear end of the gap of the supporting track 63, and can extend a section of the track under the drive of the telescopic driving member, and the extended section of the track is fitted with the connecting track section 341, so that the corresponding gap 631 is in a closed state. At this time, the hanger 200 transported on the storage entry circular track 23 will continue to move forward when passing through the distribution component 26i, and will not enter the corresponding cargo storage line 25i; in addition, the telescopic track section 342 can also retract the extended section of the track under the drive of the telescopic driving member, so that the corresponding gap 631 is in an open state. At this time, the hanger 200 will directly enter the corresponding cargo storage line 25i through the gap 631 when passing through the distribution component 26i.

[0105] Figure 9 yes Figure 7 An enlarged view of the inner part of the middle frame D. In order to clearly illustrate the structure of this part, Figure 7 The structure in the middle frame D is rotated and enlarged to obtain Figure 9 . Figure 10 4 is a structural diagram of a storage line blocking portion in an embodiment of the present invention.

[0106] like Figure 1 、 Figure 7 、 Figure 9 and Figure 10 As shown, one end of the cargo storage line 25i is connected to the storage entry circular track 23, and the other end is connected to the sorting entry circular track 24. The cargo storage line 25i is further provided with a storage line blocking portion 40 at one end close to the sorting entry circular track 24, for blocking or releasing the hangers 200 at that position.

[0107] The storage line blocking portion 40 has a blocking rod 401 and a blocking rod driving cylinder 402 connected to the blocking rod 401. The blocking rod 401 can be turned under the drive of the blocking rod driving cylinder 402. Figure 9 and Figure 10 When the position shown in FIG. 1 is reached, the gear lever 401 blocks the hanger 200 at one end of the cargo storage line 25i. Figure 10 When the direction indicated by the middle arrow turns, the lever 401 releases the hanger 200 at one end of the cargo storage line 25i, and the hanger 200 moves along the Figure 9 Move in the direction indicated by the middle arrow D5, enter the transfer track 41 after being guided by the turning guide transfer member 73, and follow Figure 9 Move in the direction indicated by the middle arrow D6, the transfer track 41 is connected to the sorting entry circular track 24, and the transfer track 41 is inclined downward along the conveying direction, so that the hanger 200 can slide down through the transfer track 41 and be hooked by the format component 222 on the sorting entry circular track 24, thereby entering the sorting entry circular track 24.

[0108] Figure 11 Schematic diagram of the distribution position of the distribution carrier reader in an embodiment of the present invention.

[0109] like Figure 11 As shown, m dispensing carrier readers 313i are respectively arranged on the storage entry circular track 22 at upstream positions of the corresponding dispensing components 26i for reading the carrier identification codes of the passing hangers 200.

[0110] In this embodiment, the distribution carrier reader 313i is an RFID reader, which is fixedly installed on the side of the storage entry circular track 23 by a bracket. Its height position corresponds to the position of the hanger 200 when it passes on the storage entry circular track 23. Therefore, it can read the RFID tag on the hanger 200 when it passes, and does not hinder the movement of the hanger 200 on the storage entry circular track 23.

[0111] Figure 12 This is a structural diagram of the connection between the sorting transfer mechanism and the cargo sorting line in an embodiment of the present invention.

[0112] like Figure 12 As shown, the sorting transfer mechanism 107 includes a storage output circular track 24 composed of a format-type conveying track, a sorting entry circular track 27 composed of a bird hook-type conveying track, and a sorting connecting line 36 connecting the two circular tracks. The n cargo sorting lines 29j are connected to the sorting entry circular track 27 in sequence.

[0113] like Figure 7 and Figure 12 As shown, the structure of the transfer mechanism 107 for sorting is consistent with the structure of the transfer mechanism 106 for warehousing, and the connection structure between the transfer mechanism 107 for sorting and the n cargo sorting lines 29j is also consistent with the connection structure between the transfer mechanism 106 for warehousing and the m cargo storage lines 25i, which will not be repeated here.

[0114] A sorting line blocking portion 42 is provided at one end of the goods sorting line 29j close to the sorting output circular track 28. Its structure and working principle are consistent with those of the storage line blocking portion 40, and will not be repeated here.

[0115] The sorting entry circular track 27 is further provided with a sorting entry blocking portion 271 for temporarily storing the unsuccessfully sorted hangers 200 on the sorting entry circular track 27 .

[0116] Figure 13 It is a structural diagram of the sorting entry blocking part in an embodiment of the present invention.

[0117] like Figure 12 and Figure 13 As shown, the sorting entry blocking portion 271 is embedded in the upstream position of the connection between the sorting entry circular track 27 and the sorting connection line 36, that is, Figure 12 The position indicated by B2 is used to block hangers 200 that have not entered the goods sorting line 29j, temporarily storing them there. Specifically, the sorting entry blocking member 271 comprises a movable block 2711 disposed within a groove on the sorting entry circular track 27 and a driving cylinder 2712. The driving cylinder 2712 can move the movable block 2711 up and down, thereby blocking or allowing the hangers 200 to pass.

[0118] Figure 14 Schematic diagram of the installation of a diversion vehicle reader in an embodiment of the present invention.

[0119] like Figure 14 As shown, n diverter assemblies 39j are respectively disposed at the junction of the sorting entry circular track 27 and each cargo sorting line 29j, and are used to connect or disconnect the sorting entry circular track 27 from the corresponding cargo sorting line 29j. The structure and operating principle of the diverter assemblies 39j are consistent with those of the distribution assembly 26i and will not be repeated here.

[0120] N diverter carrier readers 317j are positioned upstream of and adjacent to the corresponding diverter assemblies 39j, and are used to read the carrier identification codes of passing hangers 200. In this embodiment, the diverter carrier readers 317j are RFID readers, fixedly mounted on the side of the sorting entry circular track 27 via brackets. Their height corresponds to the position of hangers 200 as they pass along the sorting entry circular track 27. Therefore, they can read the RFID tags on the passing hangers 200 without hindering the movement of the hangers 200 along the sorting entry circular track 27.

[0121] The warehousing control unit 301 is used to control the operation of various components related to warehousing in the control device 30, including: allocating cargo storage lines 25i to each hanger 200 based on production batches and predetermined cargo warehousing rules; controlling the allocation component 26i to connect the corresponding cargo storage line 25i with the storage entry circular track 23 based on the carrier identification code; and controlling the warehousing transfer mechanism 106 to transfer the hanger 200 to the corresponding cargo storage line 25i.

[0122] The warehousing control unit 301 also stores predetermined rules for goods entry. In this embodiment, these rules assign clothing from the same production batch to the same or several consecutive goods storage lines 25i, and set a storage limit for each of these lines. For example, if a storage line 25i can hold a maximum of 10 hangers 200, the warehousing control unit 301 will assign hangers 200 1-10 to storage line 251, hangers 200 11-20 to storage line 252, and so on.

[0123] The sorting control unit 304 is used to control the work of various components related to classification and picking in the control device 30, including: based on the cargo identification information and the predetermined cargo retrieval rules, controlling the sorting transfer mechanism 107 to take out each hanger 200 from the cargo storage line 25i and transport the hanger 200 to the sorting entry circular track 27; based on the cargo identification information and the predetermined cargo sorting rules, allocating the cargo sorting line 29j to each hanger 200; based on the carrier identification code, controlling the diversion component 39j to connect the corresponding cargo sorting line 29j with the sorting entry circular track 27; controlling the sorting transfer mechanism 107 to transport the hanger 200 to the corresponding cargo sorting line 29j.

[0124] The sorting control unit 304 also stores predetermined rules for removing goods and sorting goods. In this embodiment, the rules for removing goods are to sequentially remove garments from the same production batch on multiple cargo storage lines 25i; the rules for sorting goods are to sort garments whose attribute information includes sorting attributes to the same cargo sorting line 29j or to several consecutive cargo sorting lines 29j.

[0125] like Figure 2 As shown, specifically, the sorting control unit 304 includes an attribute acquisition unit 3041 , a sorting allocation unit 3042 , a sorting determination unit 3043 and a diversion control unit 3044 .

[0126] The attribute acquisition unit 3041 searches the information storage unit 34 based on the carrier identification code read by the diversion carrier reader 317 j to acquire the attribute information of the clothing on the hanger 200.

[0127] The sorting allocation unit 3042 is used to allocate and set a corresponding cargo sorting line 29j for each sorting attribute. The sorting allocation unit 3042 includes a quantity counting part 30421, a sorting line calculating part 30422 and a sorting line setting part 30423.

[0128] The quantity statistics part 30421 is used to count the total quantity of goods corresponding to the sorting attributes in the same batch of goods.

[0129] In this embodiment, the sorting attribute is set to color, which includes white and black. The quantity counting part 30421 traverses the goods information storage table and finds that there are 10 pieces of clothing corresponding to the sorting attribute "white" and 40 pieces of clothing corresponding to the sorting attribute "black".

[0130] The sorting line calculation part 30422 is used to calculate the required number of cargo sorting lines 29j for each sorting attribute based on the total quantity corresponding to each attribute obtained by the quantity statistics part 30421.

[0131] In this embodiment, there are 10 white garments in total, and it is calculated that one cargo sorting line 29j is required for the sorting attribute "white". There are 40 black garments in total, and it is calculated that four cargo sorting lines 29j are required for the sorting attribute "black".

[0132] The sorting line setting part 30423 is used to set a corresponding number of cargo sorting lines 29j for each sorting attribute based on the number of cargo sorting lines 29j obtained by the sorting line calculation part 30422.

[0133] In this embodiment, based on the calculation results of the sorting line calculation part 30422, with the rule that each cargo sorting line 29j can store a maximum of 10 pieces of clothing, cargo sorting line 291 is assigned to the sorting attribute "white", and cargo sorting lines 292 to 295 are assigned to the sorting attribute "black".

[0134] The sorting determination unit 3043 determines the goods sorting line 29j to which the hanger 200 should enter based on the attribute information and the sorting attribute.

[0135] In this embodiment, according to the setting of the sorting line setting part 30423, white clothing should enter the current cargo sorting line 291. The clothing corresponding to the hanger 200 has attributes such as "white, size L, summer style, pure cotton material", and the attributes of the clothing include the sorting attribute "white". Therefore, the sorting determination unit 3043 determines that the hanger 200 should enter the current cargo sorting line 291.

[0136] The diversion control unit 3044 controls the diversion component 26b to connect or disconnect the sorting entry circular track 27 with the goods sorting line 29 according to the determination result of the sorting determination unit 3213, thereby completing the classification and sorting of the hangers 200.

[0137] In this embodiment, according to the determination result of the sorting determination unit 3043, the hanger 200 with white clothing should enter the current cargo sorting line 291. The diversion control unit 3044 controls the corresponding diversion component 391 to connect the sorting entry circular track 27 with the current cargo sorting line 291, so that the hanger 200 enters the current cargo sorting line 291.

[0138] Figure 15 4 is a workflow diagram of the goods shelving process in an embodiment of the present invention.

[0139] like Figure 15 As shown, in the implementation of the present invention, the process of putting 100 hangers 200 of the same production batch on the shelves includes the following steps:

[0140] Step S1-1:

[0141] The operator starts the storage circular track 22 and the storage entry circular track 23 through the operation terminal, that is, starts the corresponding storage driving unit and storage entry driving unit through the storage control unit 301, and then enters step S1-1a.

[0142] Step S1-1a:

[0143] Set k=1, that is, specify the first hanger 200. Then go to step S1-2.

[0144] Step S1-2:

[0145] The operator uses a handheld scanner to read the carrier identification code of the k-th hanger 200 and the cargo identification information of the clothing on the hanger 200. Then, the process proceeds to step S1-3.

[0146] Steps S1-3:

[0147] The warehousing control unit 301 controls the information storage unit 34 to store the read carrier identification code and the cargo identification information in correspondence, thereby binding the garments to the corresponding hangers 200. Then, the process proceeds to step S1-4.

[0148] Steps S1-4:

[0149] The warehousing control unit 301 allocates the goods storage line 25i to the k-th hanger 200. Then, the process proceeds to step S1-5.

[0150] Steps S1-5:

[0151] The operator hangs the hanger 200 on the upper line segment 211 of the goods loading line 21. Then proceed to step S1-6.

[0152] Steps S1-6:

[0153] It is determined whether k is equal to 100, that is, whether all the hangers 200 of this batch have been put on the shelves. If it is determined to be yes, the clothes of this batch have been put on the shelves. If it is determined to be no, the process proceeds to step S1-6a.

[0154] Step S1-6a:

[0155] Set k=k+1, that is, designate the next hanger 200. Then return to step S1-2.

[0156] Figure 16 It is a workflow diagram of the goods warehousing process in an embodiment of the present invention.

[0157] like Figure 16 As shown, in the above-mentioned steps of the goods shelving process, after a hanger 200 is hung on the upper line segment 211 of the goods shelving line 21, the warehousing process of the hanger 200 includes the following steps:

[0158] Step S2-1:

[0159] The hanger 200 slides on the upper segment 211 by gravity to the connection between the upper segment 211 and the rising segment 213. Then, the process proceeds to step S2-2.

[0160] Step S2-2:

[0161] The hoist lifts the hanger 200 along the ascending section 213 to the upper line buffer section 212. Then enter step S2-3.

[0162] Step S2-3:

[0163] The hanger 200 slides from the upper line buffer section 212 to the storage ring track 22 by gravity. Then, the process proceeds to step S2-4.

[0164] Step S2-4:

[0165] The storage driving unit drives the structural member 222 to move the hanger 200 on the storage circular track 22. Then, the process proceeds to step S2-4a.

[0166] Step S2-4a:

[0167] Set k=1, that is, designate the first dispensing carrier reader 261. Then proceed to step S2-5.

[0168] Step S2-5:

[0169] The storage drive unit drives the structural member 222 to move the hanger 200 to the distribution carrier reader 26k, and then proceeds to step S2-6.

[0170] Step S2-6:

[0171] The distribution carrier reader 26k reads the carrier identification code of the hanger 200. Then, the process proceeds to step S2-7.

[0172] Step S2-7:

[0173] The storage control unit 301 searches the cargo storage line 25i that the hanger 200 should enter based on the read carrier identification code, and then proceeds to step S2-8.

[0174] Step S2-8:

[0175] Determine whether k is equal to i, that is, whether the cargo storage line 25k corresponding to the current assigned carrier reader 26k is the cargo storage line 25i that the hanger 200 should enter. If the judgment is yes, go to step S2-9; if the judgment is no, go to step S2-8a.

[0176] Step S2-8a:

[0177] Set k=k+1, that is, designate a dispensing carrier reader 26k, and then return to step S2-5.

[0178] Step S2-9:

[0179] The storage control unit 301 controls the distribution unit 26k to connect the corresponding goods storage line 25k and the storage entry circular track 23. Then, the process proceeds to step S2-10.

[0180] Step S2-10:

[0181] The hanger 200 moves to the distribution assembly 26k and enters the corresponding cargo storage line 25k to complete the storage.

[0182] Figure 17 This is a workflow diagram for taking out goods to be sorted from the same production batch in an embodiment of the present invention.

[0183] like Figure 17 As shown, the process of taking out a batch of goods to be sorted includes the following steps:

[0184] Step S3-1:

[0185] The operator inputs the production batch, total quantity and sorting attributes of the garments to be sorted through the operation terminal, and then enters step S3-2.

[0186] Step S3-2:

[0187] The operator activates the storage output circular track 24 and the sorting entry circular track 27 through the operation terminal, that is, the sorting control unit 304 activates the corresponding storage output drive unit and sorting entry drive unit. Then, the process proceeds to step S3-3.

[0188] Step S3-3:

[0189] The sorting allocation unit 3042 allocates corresponding goods sorting lines 29j to 29j+a for each sorting attribute, and then proceeds to step S3-4.

[0190] Step S3-4:

[0191] The sorting control unit 304 obtains the storage lines 25i to 25i+b of the goods to be taken out based on the production batch query, and then enters step S3-4a.

[0192] Step S3-4a:

[0193] Set k=i, that is, specify the first cargo storage line 25i from which the hanger 200 is to be taken out. Then enter step S3-5.

[0194] Steps S3-5:

[0195] The sorting control unit 304 controls the storage line blocking unit 40 of the goods storage line 25k to release the hanger 200. Then, the process proceeds to step S3-6.

[0196] Steps S3-6:

[0197] The sorting control unit 304 waits for a predetermined time, that is, waits for all the hangers 200 on the cargo storage line 25k to be taken out, and then enters step S3-7.

[0198] Steps S3-7:

[0199] Determine whether k is equal to i+b, that is, whether the last cargo storage line 25i+b from which the hangers 200 are to be taken out has been designated. If not, proceed to step S3-7a; if yes, complete the removal of the batch of clothes to be sorted.

[0200] Step S3-7a:

[0201] Set k=k+1, that is, specify the next cargo storage line 25k, and then return to step S3-5.

[0202] In the above process, after the clothes hanger 200 is released and leaves the cargo storage line 25i, it enters the sorting entry circular track 27 through the turning guide connecting member 73 and the transfer track 41.

[0203] Figure 184 is a workflow diagram of the cargo sorting process in an embodiment of the present invention.

[0204] like Figure 18 As shown, when a clothes hanger 200 to be sorted is taken out from the goods storage line 25i, the sorting and sorting process of the clothes hanger 200 includes the following steps:

[0205] Step S4-1:

[0206] The hanger 200 moves into the sorting entry circular track 27. Then, the process proceeds to step S4-2.

[0207] Step S4-2:

[0208] The sorting entry drive unit drives the structural member 222 to drive the hanger 200 to move on the sorting entry circular track 27. Then, step S4-2a is entered.

[0209] Step S4-2a:

[0210] Set k=1, that is, specify the first diversion carrier reader 3171 along the conveying direction, and then proceed to step S4-3.

[0211] Step S4-3:

[0212] The sorting entry drive unit drives the structural member 222 to move the hanger 200 to the diversion carrier reader 317k, and then enters step S4-4.

[0213] Step S4-4:

[0214] The carrier reader 317k reads the carrier identification code of the hanger 200. Then, the process proceeds to step S4-5.

[0215] Step S4-5:

[0216] The attribute acquisition unit 3041 acquires attribute information of the clothing on the hanger 200 according to the read carrier identification code, and then proceeds to step S4-6.

[0217] Steps S4-6:

[0218] The sorting line determination unit 3042 determines whether the hanger 200 should enter the corresponding goods sorting line 29k based on the acquired attribute information. If the determination is yes, the process proceeds to step S4-7; if the determination is no, the process proceeds to step S4-9.

[0219] Steps S4-7:

[0220] The sorting control unit 304 controls the diverter assembly 39k to connect the goods sorting line 29k with the sorting entry circular track 27. Then, the process proceeds to step S4-8.

[0221] Steps S4-8:

[0222] The hanger 200 moves to the diversion component 39k and enters the connected goods sorting line 29k to complete the sorting of the hanger 200.

[0223] Steps S4-9:

[0224] Determine whether k is equal to n, that is, whether the current diversion vehicle reader 317k is the last diversion vehicle reader 317n along the conveying direction. If so, proceed to step S4-10; if not, proceed to step S4-9a.

[0225] Step S4-9a:

[0226] Set k=k+1, that is, designate the next diversion carrier reader 317k, and then return to step S4-3.

[0227] Steps S4-10:

[0228] The sorting entry driving unit driving structural component 222 drives the hanger 200 to move to the sorting entry blocking portion 271 for temporary storage.

[0229] During the above process, if the hanger 200 does not enter any of the cargo sorting lines 29j, it will continue to move forward under the drive of the sorting entry drive unit until it is blocked at the sorting entry blocking member 271. After the operator observes the phenomenon of clothing retention, the hangers 200 that have not been successfully sorted on the sorting entry circular track 27 can be collected and put back online for processing.

[0230] <Example 2>

[0231] This embodiment provides a batch-type storage and sorting system 100 without fixed shelves.

[0236] like Figure 19 and Figure 20 As shown, compared with the first embodiment, in this embodiment, the reading unit 31 has only one diversion vehicle reader 3171, which is arranged at the upstream position of the most upstream diversion component 391; at the same time, in this embodiment, the reading unit 31 also has a moving speed acquirer 314 for acquiring the moving speed of the hanger 200 on the sorting entry circular track 27, and the moving speed acquirer 314 is arranged at approximately the same position as the diversion vehicle reader 3171.

[0237] The moving speed acquirer 314 includes a photoelectric sensor and a speed calculation unit. The photoelectric sensor is embedded in the cargo storage entry circular track 23 and senses the presence of passing birdhook conveyor units 61. The speed calculation unit calculates the moving speed based on the number of birdhook conveyor units 61 passing per unit time and the spacing between adjacent birdhook conveyor units 61. In this embodiment, since the birdhook conveyor units 61 are closely adjacent to each other, the spacing between adjacent birdhook conveyor units 61 is equal to the length of the birdhook conveyor units 61.

[0238] In this embodiment, the sorting allocation unit 3042 allocates the cargo sorting line 29j to the hanger 200 in the same manner. The sorting determination unit 3043 calculates the arrival time of the hanger 200 at the cargo sorting line 29j to be entered based on the above-mentioned moving speed, and determines whether the hanger 200 should enter the current cargo sorting line 29k based on the arrival time.

[0239] Figure 21 1 is a workflow diagram of the cargo sorting process in an embodiment of the present invention.

[0240] like Figure 21 As shown, the cargo sorting process in this embodiment includes steps S5-1 to S5-10. Except for the above description, they basically correspond to steps S4-1 to S4-10 of the cargo sorting process in the first embodiment, and therefore will not be repeated.

[0241] <Example 3>

[0242] This embodiment provides a batch-type storage and sorting system 100 without fixed shelves.

[0243] In the first embodiment, the reading unit 31 has n diverter carrier readers 317j, which are respectively arranged at upstream positions of the n diverter components 39j on the sorting entry circular track 27 to read the carrier identification code of the passing hanger 200.

[0244] Figure 22 This is a structural block diagram of a batch-type non-fixed shelf storage and sorting system in an embodiment of the present invention.

[0245] Figure 23Schematic diagram of the distribution of the diversion vehicle reader and the cargo location reader in an embodiment of the present invention.

[0246] like Figure 22 and Figure 23 As shown, compared to the first embodiment, in this embodiment, the reading unit 31 includes a diverting carrier reader 3171, located downstream of the connection between the sorting entry circular track 27 and the sorting connection line 36. Furthermore, the reading unit 31 includes n+1 cargo location readers for reading the cargo location identification codes of passing bird hook conveyor units 61. One cargo location reader, serving as a binding cargo location reader 315, is located at the diverting carrier reader 320. The remaining n cargo location readers, serving as diverting cargo location readers 316j, are located upstream of the n diverting components 39j.

[0247] When the hanger 200 passes through the binding cargo location reader 315, the binding cargo location reader 315 reads the cargo location identification code of the bird hook type conveyor unit 61 corresponding to the hanger 200, and the sorting control unit 304 controls the information storage unit 34 to store the cargo location identification code of the bird hook type conveyor unit 61, the carrier identification code of the hanger 200 and the cargo identification information of the clothes in correspondence to achieve binding of the three.

[0248] Subsequently, when the clothes hanger 200 reaches the position of the diversion cargo location reader 316j, the diversion cargo location reader 316j reads the cargo location identification code of the corresponding bird hook seat, the attribute acquisition unit 3041 obtains the attribute information of the clothing according to the cargo location identification code, and the sorting determination unit 3043 determines whether the clothes hanger 200 should enter the current cargo sorting line 29k according to the attribute information.

[0249] Figure 24 1 is a workflow diagram of the cargo sorting process in an embodiment of the present invention.

[0250] like Figure 24 As shown, the cargo sorting process of this embodiment includes steps S6-1 to S6-12, which, except for the above description, correspond to steps S4-1 to S4-10 in the first embodiment, and thus will not be repeated.

[0251] <Example 4>

[0252] The present invention provides a batch-type storage and sorting system 100 without fixed shelves.

[0254] Figure 26 Schematic diagram of the distribution position of full-load sensors on the sorting line in an embodiment of the present invention.

[0255] like Figure 25 and Figure 26 As shown, compared to the first embodiment, the control device 30 in this embodiment further includes a sensing unit 32 comprising n sorting line full load sensors 325j, each positioned at one end of each of the n sorting lines 29j near the sorting entry circular track 27, for sensing the arrival of hangers 200 at that location. In this embodiment, the sorting line full load sensors 325j are photoelectric sensing units embedded in the sorting lines 29j near one end of the sorting entry circular track 27. If an excessive number of hangers 200 are carried on a sorting line 29j and an upstream hanger 200 reaches the location of the sorting line full load sensor 325j, the sorting line full load sensor 325j generates a corresponding full load signal.

[0256] When the sorting line full load sensor 325j senses the hanger 200 and generates a full load signal, the sorting control unit 304 controls the corresponding diversion component 39j to disconnect the corresponding cargo sorting line 29j from the sorting entry circular track 27, so that the hanger 200 no longer enters the fully loaded cargo sorting line 29j.

[0257] Figure 27 1 is a workflow diagram of the cargo sorting process in an embodiment of the present invention.

[0258] like Figure 27 As shown, in this embodiment, the cargo sorting process includes steps S7-1 to S7-11, which, except for the above description, correspond to steps S4-1 to S4-10 in the first embodiment, and thus will not be repeated.

[0259] <Example 5>

[0260] This embodiment provides a batch-type storage and sorting system 100 without fixed shelves.

[0261] In the first embodiment, the clothes hangers 200 that have not been successfully sorted are stranded on the sorting entry circular track 27. After observing this phenomenon, the operator can collect and re-shelf these clothes hangers 200.

[0262] Figure 28 It is a structural diagram of a batch-type non-fixed shelf storage and sorting system in an embodiment of the present invention.

[0263] like Figure 1 and Figure 28As shown, compared with the first embodiment, in this embodiment, the sorting transfer mechanism 107 further has a sorting return conveying track 272, which is connected between the sorting entry circular track 27 and the warehousing circular track 22, and is used to convey the hangers 200 on the sorting entry circular track 27 that have passed through all the goods sorting lines 29j and have not entered any of the goods sorting lines 29j back to the warehousing circular track 22, so that these hangers 200 can be re-warehoused for storage.

[0264] The structure of the sorting return conveying track 272 is consistent with that of the , which is a bird hook type conveying track. A return blocking part is provided at one end close to the circular track 22 for storage. The structure of the return blocking part is consistent with the structure of the storage line blocking part 40, and the description is not repeated here. The supporting track 63 at one end of the sorting return conveying track 272 close to the circular track 22 for storage is connected with a turning guide connecting component 72, which can release the hanger 200 from the bird hook type conveying unit 61 and transfer it to the format component 222 of the circular track 22 for storage when it reaches this position. It will not be repeated here.

[0265] Example Function and Effect

[0266] According to the batch-type non-fixed shelf storage and sorting system 100 provided in the first embodiment, it includes a storage device 101, a storage device 102, a sorting device 103, a storage device 104, and a control device 30. The storage device 101 has a cargo loading line 21 and a storage transfer mechanism 106. The storage device 102 has m cargo storage lines 25i for storing hangers 200 according to different batches. The sorting device 103 includes n cargo sorting lines 29j and a sorting transfer mechanism 107. The control device 30 has an information storage unit 34, a reading unit 31, and a storage control unit 301. , sorting control unit 304, and outbound control unit 305. The information storage unit 34 stores the cargo identification information, attribute information, and corresponding carrier identification code of the cargo carrier. Therefore, the sorting control unit 304 can control the sorting transfer mechanism 107 to receive the batched warehoused hangers 200 from the storage device 102 based on the carrier identification code of the hanger 200, the cargo identification information, and attribute information of the clothing, according to the sorting attributes when sorting the clothing. It then transfers each hanger 200 to the cargo sorting line 29j corresponding to its attribute, thereby achieving automated classification and picking based on the clothing attribute information. In addition, because the batch-type non-fixed shelf storage and sorting system 100 of this embodiment uses rails for transportation and storage, it does not require the construction of fixed shelves, nor does it require the use of stackers, shuttles, and other transportation equipment. It is easy to build and low-cost.

[0267] Specifically, the warehousing transfer mechanism 106 has a circular track 22 for warehousing, a circular track 23 for storage entry, a connecting line 35 for warehousing and m distribution components 26i. The reading unit 31 has m distribution carrier readers 313i, which are arranged at the upstream position of the corresponding distribution components 26i. The warehousing control unit 301 also stores predetermined goods warehousing rules, so that warehousing is carried out according to production batches. Therefore, the control device 30 can control the hangers 200 according to the production batch information and the carrier identification code read by the distribution carrier reader 313i to be stored in the goods storage line 25i in sequence according to the batch information, so that the warehousing efficiency is high and the degree of automation is high.

[0268] Furthermore, the sorting transfer mechanism 107 has a storage output circular track 24, a sorting entry circular track 27, a sorting connecting line 36 and n diversion components 39j. The reading unit 31 has n diversion carrier readers 317j, which are arranged at the upstream position of the corresponding diversion components 39j. The sorting control unit 304 also stores predetermined cargo sorting rules for classification and picking according to sorting attributes. Therefore, the control device 30 can control the hangers 200 according to the attribute information of the clothing and the carrier identification code read by the diversion carrier reader 317j to be stored in each cargo sorting line 29j according to the sorting attributes. The sorting efficiency is high, the degree of automation is high and the error probability is low.

[0269] Specifically, the sorting control unit 304 has an attribute acquisition unit 3041, so it can obtain the attribute information of the clothing corresponding to the hanger 200. Since it has a sorting allocation unit 3042, it can set the corresponding cargo sorting line 29j for each sorting attribute allocation. Since it has a sorting determination unit 3043, it can determine the cargo sorting line 29j that the hanger 200 should enter based on the attribute information and sorting attributes of the clothing. Also, since it has a diversion control unit 3044, it can control the diversion component 39j to connect the sorting entry circular track 27 with the cargo sorting line 29j that should be entered, so that the hanger 200 can enter the cargo sorting line 29j allocated according to the sorting attributes.

[0270] In the second embodiment, the reading unit 31 includes a diverter reader 3171 and a movement speed detector 314. This allows the reader to detect the movement speed of the hanger 200 on the sorting entry circular track 27. Based on the movement speed, the arrival time of the hanger 200 at the intended goods sorting line 29j is calculated. Based on this arrival time, the reader 31 controls the diverter assembly 39j to connect the sorting entry circular track 27 with the intended goods sorting line 29j, thereby allowing the hanger 200 to enter the intended goods sorting line 29j. This embodiment's reading unit 31 comprises only two readers, resulting in a relatively simple structure and lower cost. Furthermore, the speed-based control method also ensures a smooth sorting process.

[0271] In Example 3, the reading unit includes a diversion carrier reader 3171 and n+1 cargo location readers, one of which serves as a binding cargo location reader 315, and the remaining n cargo location readers 316j are located upstream of the corresponding diversion component 39j. The distribution and control method of the readers in Example 3 are very similar to those in Example 1. The difference is that Example 1 controls by reading the carrier identification code of the hanger 200, while Example 3 controls by reading the cargo location identification code of the corresponding bird hook seat. As the hanger 200 moves on the track, it may shake due to movement speed, environmental factors, and other factors, which may slightly affect the reading of the carrier identification code. The bird hook seat, on the other hand, moves via a pulley system embedded in the track, which is relatively stable. Therefore, the control method based on the cargo location identification code is more accurate, the probability of sorting errors is reduced, and the need for manual intervention is correspondingly reduced.

[0272] In the fourth embodiment, the control device 30 further includes a sensing unit 32, which includes n sorting line full-load sensors 325j. These sensors are located on the corresponding goods sorting line 29j, near one end of the sorting entry circular track 27. When the goods sorting line 29j is full, they generate a corresponding full-load signal. Therefore, the sorting control unit 304 can control the corresponding diversion component 39j to disconnect the goods sorting line 29j from the sorting entry circular track 27 when the goods sorting line 29j is full. This prevents excessive hangers 200 from being stacked on the goods sorting line 29j and affecting subsequent sorting and warehousing. This further improves the reliability of the system.

[0273] In the fifth embodiment, since the sorting transfer mechanism 107 also has a sorting return conveying track 272, the hangers 200 that have not been successfully sorted and are stranded on the sorting entry circular track 27 can be transported back to the warehousing circular track 22 through the sorting return conveying track 272, so that these hangers 200 can be automatically re-warehoused for storage without the need for manual intervention, further reducing manpower.

[0274] The above embodiments are only used to illustrate specific implementations of the present invention, and the present invention is not limited to the description scope of the above embodiments.

[0275] In the above embodiment, the number of cargo storage lines 25i is 100 and the number of cargo sorting lines 29j is 30. In other embodiments of the present invention, fewer or more cargo storage lines 25i and cargo sorting lines 29j may be configured according to actual needs.

[0276] In the above embodiment, the batch-type non-fixed shelf storage and sorting system 100 includes a sorting device 103. After the clothes are sorted once, they are directly transported to the corresponding operation table for packaging and shipment. In other solutions of the present invention, multiple sorting devices 103 connected in series can also be set according to actual needs, and can further automatically sort by attributes. For example, the first level of sorting is to sort by the color of the clothes, and the second level of sorting is to sort by the size of the clothes. After the two levels of sorting, the clothes are transported to the corresponding operation table for packaging and shipment.

[0277] In the above embodiment, the operator inputs the total quantity of a batch of clothing through the operation terminal, and the control device 30 allocates the required cargo storage line 25 based on this total quantity. In other embodiments of the present invention, other methods can also be used to obtain the total quantity of a batch of clothing. For example, a corresponding reading unit is provided at the upstream position where the storage circular track 22 connects to the cargo loading line 21. The control device 30 counts based on the reading results of the reading unit, thereby automatically obtaining the total quantity of the batch of clothing. These two methods can also be used in combination, and the total quantity of the batch of clothing obtained by both methods can serve as a reference for each other, reducing the possibility of error.

[0278] In the above embodiment, the information storage unit 34 stores attribute information of the clothing, which is pre-entered by the operator through the operation terminal. In other schemes of the present invention, the control device 30 can also be connected to the production system to automatically obtain the cargo information.
