Description

Technical Field

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

[0002] Currently, a common method for cargo storage is to place goods in boxes, then sort the boxes into different categories and place them on different shelves. Conveyors are then used to transport the goods between the different storage facilities in the storage system. In this cargo storage system, the shelves are cumbersome to set up and occupy a large area. Sorting and moving the boxes requires a lot of manpower. The conveyor equipment is expensive and also requires a considerable amount of work space. Therefore, this cargo storage system suffers from the problems of cumbersome shelf setup, large space occupation, and high labor costs.

[0003] Furthermore, when applying this cargo storage system to industries where goods are in the form of soft sheets, such as the clothing industry, multiple garments are packed into the same container. This not only requires significant labor and packaging resources, but also creates wrinkles from the stacking and squeezing of garments within the container, necessitating additional steps such as flattening before shipment. Furthermore, clothing is typically sorted and stored by production batch and attributes, and clothing comes in a wide variety of materials, sizes, colors, and styles. Consequently, the classification requirements for warehousing clothing are complex, making traditional manual sorting and packaging a time-consuming process and prone to errors. Because multiple garments are stacked in the same container, misclassifications are difficult to detect.

[0004] Therefore, there is an urgent need for a non-fixed shelf storage system that does not require fixed shelves, keeps clothes flat, and is easy to classify and store. Accordingly, there is also an urgent need for a storage device for classifying and storing goods into a storage device in such a non-fixed shelf storage system. Summary of the Invention

DETAILED DESCRIPTION

[0048] To facilitate understanding of the technical means, creative features, objectives, and effects of the present invention, the following describes a storage device and a storage system without fixed shelves, using a flexible sheet storage system as an example, with reference to embodiments and accompanying drawings. The flexible sheet storage system is a clothing storage system that uses hanging racks (i.e., hangers) as cargo carriers.

[0049] <Example 1>

[0050] This embodiment provides a warehousing device and a storage system without fixed shelves.

[0051] Figure 1 It is a structural diagram of a storage system without fixed shelves in this embodiment.

[0052] like Figure 1 As shown, the non-fixed shelf storage system 100 of this embodiment is a non-fixed shelf storage system that uses rails to transport and store cargo carriers (hangers) carrying goods (clothing), including a warehousing device 110, a sorting and out-of-warehouse device 111 and multiple cargo storage lines 25i, 1≤i≤n, and in this embodiment, n=100.

[0053] The warehousing device 110 is used to store hangers carrying clothing into multiple cargo storage lines 25i, and multiple cargo storage lines 25i are used to store (or classify and store) the hangers. The sorting and unloading device 111 is used to classify and pick the hangers stored in the cargo storage lines 25i and unload (or further classify and unload). Figure 1 In the figure, each straight line segment or loop line represents a different track, and the arrows on these lines indicate the direction of movement of the cargo carrier on the corresponding track.

[0054] The warehousing device 110 comprises multiple loading lines 21, a warehousing circular track 22, a connecting line 35, and a storage and entry circular track 23. The loading lines 21 receive hangers carrying garments to be stored. The warehousing circular track 22 receives hangers from the loading lines 21 and transports them to the storage and entry circular track 23. The storage and entry circular track 23 receives hangers from the loading circular track 22 and distributes them to multiple storage lines 25i. These storage lines 25i are designated as storage line 251, storage line 252, ..., storage line 25i, ..., storage line 25n, in the order of transport along the storage and entry circular track 23. The connecting line 35 connects the warehousing circular track 22 and the storage and entry circular track 23.

[0055] from Figure 1 It can be directly seen from the figure that the circular track 22 for storage entry and the circular track 23 for storage entry in this embodiment are circular tracks, and the cargo storage line 25i is a linear track.

[0056] Figure 2 It is a structural block diagram of the warehousing device in the first embodiment of the present invention. Figure 3 It is a structural diagram of the warehousing device in Example 1 of the present invention.

[0057] like Figure 2 and Figure 3 As shown, the warehousing device 110 of this embodiment includes two cargo loading lines 21, a circular track 22 for warehousing, a circular track 23 for storage entry, a connecting line 35, a control unit 30, a reading unit 31, a sensing unit 32 and an information storage unit 34.

[0058] The control unit 30 is used to control the process of goods entering the warehouse. The control unit 30 includes a warehouse entry control unit 301, an online control unit 302 and a connection control unit 303.

[0059] The reading unit 31 is used to read the carrier identification code of the hanger passing through a predetermined position.

[0060] The reading unit 31 includes a vehicle identification code reader 311, a cargo information reader 312, and a diverter vehicle reading unit 313. The diverter vehicle reading unit 313 has n diverter vehicle readers 313i, where 1≤i≤n. In this embodiment, n=100.

[0061] The sensing portion 32 is used to sense a clothes hanger passing a predetermined position.

[0062] The sensing unit 32 includes a full load sensor 321, a line driving sensor 322, a full load sensor 323, and a line monitoring sensing unit 324. The line monitoring sensing unit 324 has a line monitoring sensor 3241 and a line monitoring sensor 3242, corresponding to the two cargo loading lines 21 respectively.

[0063] The information storage unit 34 has a cargo information storage table, which stores cargo identification information, attribute information, and corresponding carrier identification code of each cargo. These attribute information include the color, size, production batch, order information, etc. of the clothing. In this embodiment, the structure of the cargo information storage table and the stored information are shown in Table 1.

[0064] Table 1 Cargo information storage table

[0065]

[0066] Figure 4 2 is a structural diagram of a cargo loading line in an embodiment of the present invention.

[0067] like Figure 4 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.

[0068] 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 .

[0069] 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.

[0070] 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.

[0071] 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.

[0072] The upper line driving unit 333 is used to drive the hanger 200 that has reached 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 .

[0073] Figure 5 2 is a structural diagram of the upper line blocking portion in the first embodiment of the present invention.

[0074] like Figure 5 As shown, the upper line blocking portion 332 is embedded in the upper line buffer section 212 near the end of the storage circular track 22, that is, Figure 4 At position B1, the upper line blocking portion 332 is used to block or release the hanger 200 on the upper line buffer section 212 that is about to enter the storage circular track 22. Specifically, the upper line blocking portion 332 includes a movable block 3321 disposed in a groove on the upper line buffer section 212 and a driving cylinder 3322. The driving cylinder 3322 can drive the movable block 3321 to move up and down, thereby blocking or releasing the hanger 200.

[0075] like Figure 4 As shown, 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 4 At position B2, the 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.

[0076] 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 4 At position B2, 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.

[0077] 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, so as to realize the binding of the clothing and the hanger 200.

[0078] The upper line driving sensor 322 is arranged on the upper line segment 211 at a position close to the rising segment 213, that is, Figure 4 In this embodiment, the upper line drive sensor 322 is a photoelectric sensing unit embedded in the upper line segment 211 at the position shown in B3. Once the hanger 200 slides down from the upper line segment 211 and reaches the position of the upper line drive sensor 322, the upper line drive sensor 322 generates a corresponding signal.

[0079] The upper line full load sensor 323 is set at a position with a predetermined distance from the upper line blocking portion 332, that is, Figure 4 In this embodiment, the upper line full load sensor 323 is a photoelectric sensing unit embedded in the upper line buffer section 212 at the position indicated by B4. Once the upper line blocking portion 332 blocks an excessive number of hangers 200 and reaches the position of the upper line full load sensor 323, the upper line full load sensor 323 generates a corresponding full load signal.

[0080] Figure 6 yes Figure 3 In order to clearly illustrate the structure of the track segment of the storage ring track 22, the structure of the track segment of the storage entry ring track 23 and the structure of the connecting line 35, Figure 6 The structure in is rotated to obtain Figure 7 . Figure 7 yes Figure 3 Structural diagrams of the inner part of middle frame A at different angles.

[0081] like Figure 3 、 Figure 6 and Figure 7 As shown, the circular track 22 for storage 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, which includes a plurality of format components 222. The format component 222 is used to carry and convey 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 loading track 221 of the circular track 22 for storage. The format component 222 is moved along the circular track 22 for storage by a pulley group embedded in the circular track 22 for storage. Figure 7 Move in the direction indicated by the arrow D1.

[0082] The storage annular track 22 further includes a storage driving unit 334 for driving the movement of each format member 222. The storage driving unit 334 includes a drive motor and a plurality of drive wheels, and the specific structure can adopt a conventional structure in the prior art.

[0083] Figure 8 Schematic diagram of the distribution of online monitoring sensors in an embodiment of the present invention.

[0084] like Figure 8 As shown, the online monitoring sensor 3141 and the online monitoring sensor 3142 are respectively set at the upstream position of the connection between the storage circular track 22 and the two cargo racking lines 21, and the online monitoring sensor 3141 is set at Figure 8 At the position shown in B5, the online monitoring sensor 3142 is set Figure 8 The on-line monitoring sensor 3141 and the on-line monitoring sensor 3142 are photoelectric sensing units, respectively embedded in the storage circular track 22 at the positions indicated by B5 and B6. Once the hanger 200 reaches the position of the on-line monitoring sensor 3241 or the on-line monitoring sensor 3142, the on-line monitoring sensor 3241 or the on-line monitoring sensor 3142 generates a corresponding signal.

[0085] The storage entry circular track 23 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 straight. 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 7 Move in the direction indicated by the arrow D3.

[0086] The storage entry circular track 23 also has an entry drive unit 336 for driving the movement of each bird hook type conveying unit 61. The entry drive unit 336 has a drive motor and multiple drive wheels, and the specific structure can adopt the conventional structure in the prior art.

[0087] Figure 9 Schematic diagram of the distribution positions of the storage receiving blocking portion, the connection blocking portion and the entry full load sensor in an embodiment of the present invention.

[0088] like Figure 9 As shown, the storage entry annular track 23 further has a storage receiving blocking portion 335, which is arranged at an upstream position of the connection between the storage entry annular track 23 and the connecting line 35, that is, Figure 9 The position shown by B8 is used to block the hanger 200 that reaches this position, so that the hanger 200 can be temporarily stored at this position.

[0089] The full load sensor 321 is arranged upstream of the storage receiving barrier 335 and at a position at a predetermined distance from the storage receiving barrier 335, that is, Figure 9 The full load sensor 321 is used to sense the hangers 200. In this embodiment, the full load sensor 321 is a photoelectric sensing unit embedded in the storage entry circular track 23 at the position indicated by B9. If the number of hangers 200 blocked by the storage receiving blocking portion 335 becomes too large, and the upstream hangers 200 reach the position of the full load sensor 321, the full load sensor 321 generates a corresponding full load signal.

[0090] Figure 10 yes Figure 3 The enlarged view of the part inside the middle frame B. To clearly illustrate the structure of the diverter assembly 26i, Figure 3 The structure in frame B is enlarged and rotated to obtain Figure 10 .

[0091] like Figure 10 As shown, a plurality of diversion components 26i are respectively arranged at the connection positions with each cargo storage line 25i on the storage entry circular track 23, and are used to connect or disconnect the connection between the storage entry circular track 23 and each cargo storage line 25i, thereby realizing the release or blocking of the hanger 200, 1≤i≤n, in this embodiment, n=100.

[0092] The diverter assembly 26i includes a connecting track segment 341, a telescopic track segment 342 and a telescopic driving member (not shown in the figure).

[0093] 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 clothes hanger 200 transported on the storage entry circular track 23 will continue to move forward when passing through the diversion 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 clothes hanger 200 will directly enter the corresponding cargo storage line 25i through the gap 631 when passing through the diversion component 26i.

[0094] Figure 11 Schematic diagram of the distribution position of the vehicle reader for diversion in an embodiment of the present invention.

[0095] like Figure 11 As shown, n diversion vehicle readers 313i are respectively arranged at the upstream position of each diversion component 26i on the storage entry circular track 23, 1≤i≤n, in this embodiment, n=100, Figure 11 Only the four most upstream diverter components 26i are shown for illustration purposes.

[0096] like Figure 11 As shown in FIG, the diversion vehicle reader 3131 is set at the upstream position of the diversion component 261, that is, Figure 11 At the position shown in B10, the diversion vehicle reader 3132 is set at the upstream position of the diversion component 262, that is, Figure 11 At the position shown by B11, and so on.

[0097] The diversion vehicle reader 313i is used to read the vehicle identification code of a passing hanger 200. In this embodiment, the diversion vehicle reader 313i is an RFID reader, fixedly mounted on the side of the storage entry circular track 23 via a bracket. Its height corresponds to the position of the hangers 200 as they pass along the storage entry circular track 23. Therefore, it can read the RFID tags on the hangers 200 as they pass along the storage entry circular track 23 without hindering the movement of the hangers 200 along the storage entry circular track 23.

[0098] like Figure 7 As shown, the connecting 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 connecting line 35 is a connecting portion, including a connecting track 72, a guide transfer member 712 and a turning guide connecting member 73.

[0099] 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 7 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, once the hanger 200 enters the connecting track 72, it can slide from the upper end 721 to the lower end 722 by gravity without requiring 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 result in low conveying efficiency nor too fast to result in unstable conveying of the hanger 200.

[0100] Figure 12 yes Figure 7 Enlarged view of the portion within box C.

[0101] like Figure 7 and Figure 12As 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 the Figure 7 The direction indicated by the middle arrow D2 moves on the connecting track 72 .

[0102] 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.

[0103] 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 7 Move in the direction indicated by arrow D3.

[0104] like Figure 9 As shown, the connecting line 35 also has a connection blocking portion 337, which is provided on the connecting line 35. Figure 9 The position shown in B7 is used to block or release the hanger 200 that arrives at this position, so that the hanger 200 is temporarily stored at this position or passes through this position and enters the storage entry ring track 23.

[0105] The specific structure of the connection blocking portion 337 is consistent with that of the upper line blocking portion 332 and will not be repeated here.

[0106] As described above, the hanger 200 is put on the cargo loading line 21, lifted into the warehousing circular track 22 and moves on the warehousing circular track 22, transferred to the storage entry circular track 23 through the connecting line 35 and moves on the storage entry circular track 23, and finally moves to the cargo storage line 25i connected to the storage entry circular track 23, completing the warehousing process.

[0107] The up-line control unit 302 is used to control the operation of various components related to the up-line, including: controlling the up-line blocking unit 332 to allow the hanger 200 to pass when the up-line monitoring sensor unit 324 does not sense the hanger 200; controlling the elevator to lift the hanger 200 to the up-line buffer section 212 when the up-line drive sensor 322 senses the hanger 200; controlling the up-line drive unit 333 to suspend lifting when the up-line full load sensor 323 senses the hanger 200; and controlling the up-line blocking unit 332 to block the hanger 200 when the entry full load sensor 321 senses the hanger 200.

[0108] The warehousing control unit 301 is used to control the work of various components related to warehousing, including: allocating cargo storage lines 25i to each hanger 200 based on cargo identification information and predetermined cargo warehousing rules; controlling the diversion component 26i to connect the corresponding cargo storage line 25i with the storage entry circular track 23 based on the carrier identification code; controlling the warehousing circular track 22, the storage entry circular track 23 and the connecting line 35 to transfer the hanger 200 to the corresponding cargo storage line 25i.

[0109] The warehousing control unit 301 also stores predetermined rules for goods warehousing. These rules require that cargo carriers carrying goods with specific attribute information be warehousing-bound to the same cargo storage line or to several consecutive cargo storage lines. In this embodiment, the rules require that clothing produced in the same batch be warehousing-bound to the same cargo storage line 25i or to several consecutive cargo storage lines 25i.

[0110] The connection control unit 303 is used to control the operation of various components related to the connection, including: when the full-load sensor 321 senses the hanger 200, controlling the connection blocking part 331 to block the hanger 200.

[0111] When the operator starts to put a batch of clothes on the shelves and put them into storage, the operator starts the storage drive unit 334 and the entry drive unit 336 through the operation terminal, so that the format component 222 on the storage circular track 22 and the bird hook conveying unit 61 on the storage entry circular track 23 start to move.

[0112] Figure 13 This is a workflow diagram of the goods online process in an embodiment of the present invention.

[0113] like Figure 13 As shown, for each hanger 200, the online process includes the following steps:

[0114] Step S1-1:

[0115] The operator reads the carrier identification code of the hanger 200 and the cargo identification information of the clothes on the hanger 200 through a handheld scanner, and enters the carrier identification code and the cargo identification information one by one through the operation terminal, and then enters step S1-2.

[0116] Step S1-2:

[0117] The warehousing control unit 301 controls the information storage unit 34 to store the carrier identification code and the goods identification information in correspondence, thereby binding the clothing and the hanger 200, and then proceeds to step S1-3.

[0118] Steps S1-3:

[0119] The warehousing control unit 301 allocates a cargo storage line 25i to the hanger 200 according to the attribute information of the clothing, that is, obtains the value of i, and stores i in correspondence with the carrier identification code of the hanger 200, and then enters step S1-4.

[0120] Steps S1-4:

[0121] The operator hangs the hanger 200 on the upper line segment 211 of the goods loading line 21, and the hanger 200 slides to the connection between the upper line segment 211 and the rising segment 213 by gravity, and then enters step S1-5.

[0122] Steps S1-5:

[0123] The upper line control unit 302 determines whether the upper line driving sensor 322 senses the hanger 200 . If the determination is no, step S1 - 5 is repeated; if the determination is yes, step S1 - 6 is entered.

[0124] Steps S1-6:

[0125] The upper line control unit 302 determines whether the upper line full load sensor 323 senses the hanger 200, that is, whether the upper line buffer section 212 is fully loaded. If so, the process proceeds to step S1-7; otherwise, the process proceeds to step S1-8.

[0126] Steps S1-7:

[0127] The online control unit 302 controls the hoist to suspend lifting.

[0128] Steps S1-8:

[0129] The upper line control unit 302 controls the elevator to lift the hanger 200 to the upper line buffer section 212, and then enters step S1-9.

[0130] Steps S1-9:

[0131] The online control unit 302 determines whether the online monitoring sensor 3241 senses the hanger 200. When it is judged as yes, there is no corresponding idle position on the circular track 22 for storage, and the process goes to step S1-10. When it is judged as no, there is a corresponding idle position on the circular track 22 for storage for the hanger 200 to go online, and the process goes to step S1-11.

[0132] Steps S1-10:

[0133] The upper line control unit 302 controls the upper line blocking portion 332 to block the hanger 200 so that the hanger 200 is temporarily stored in the upper line buffer section 212 , and then returns to step S1 - 9 .

[0134] Steps S1-11:

[0135] The upper line control unit 302 controls the upper line blocking portion 332 to release the hanger 200 , and the hanger 200 moves from the upper line buffer section 212 to the storage circular track 22 .

[0136] During the above process, when too many hangers 200 are stranded on the online buffer section 212, the newly-loaded hangers 200 reach the online full-load sensor 323, so that the online full-load sensor 323 senses the hangers 200 and generates a corresponding full-load signal. The online control unit 302 controls the elevator to suspend lifting. After the operator observes the stranded phenomenon and the elevator stops working, he can recycle the hangers 200 stranded on the online buffer section 212, or manually start the elevator after the online buffer section 212 is no longer full.

[0137] Figure 14 It is a flow chart of the goods warehousing process in an embodiment of the present invention.

[0138] like Figure 14 As shown, after the clothes hanger 200 enters the storage circular track 22, the process of storing the clothes hanger 200 includes the following steps:

[0139] Step S2-1:

[0140] The storage control unit 301 controls the storage driving unit 334 to drive, and the storage driving unit 334 drives the hanger 200 to move on the storage circular track 22, and then enters step S2-2.

[0141] Step S2-2:

[0142] The hanger 200 moves to the off-track member 711, leaves the storage circular track 22 and enters the connecting line 35, and moves to the storage entry circular track 23 through the connecting line 35, and then enters step S2-3.

[0143] Step S2-3:

[0144] The entry driving unit 336 drives the hanger 200 to move along the storage entry circular track 23, and then proceeds to step S2-3a.

[0145] Step S2-3a:

[0146] Set k=1, that is, specify the first diversion vehicle reader 3131, and then enter step S2-4.

[0147] Step S2-4:

[0148] The driving unit 336 drives the hanger 200 to move to the diversion carrier reader 314k, and then enters step S2-5.

[0149] Step S2-5:

[0150] The carrier reader 314k reads the carrier identification code of the hanger 200, and then enters step S2-6.

[0151] Step S2-6:

[0152] The warehousing control unit 301 obtains the value of i according to the carrier identification code of the hanger 200 , that is, the cargo storage line 25i to be entered, and then proceeds to step S2 - 7 .

[0153] Step S2-7:

[0154] The warehousing control unit 301 determines whether k is equal to i, that is, whether the cargo storage line 25k corresponding to the current diversion carrier reader 314k is the cargo storage line 25i that the hanger 200 should enter. When the judgment is yes, it enters step S2-8; when the judgment is no, it enters step S2-10.

[0155] Step S2-8:

[0156] The warehousing control unit 301 controls the corresponding diversion component 26k to connect the cargo storage line 25k with the storage entry circular track 23, and then enters step S2-9.

[0157] Step S2-9:

[0158] The entry driving unit 336 drives the hanger 200 to move to the position of the diverter assembly 26k, and the hanger 200 enters the corresponding cargo storage line 25k.

[0159] Step S2-10:

[0160] The warehousing control unit 301 determines whether k is equal to n, that is, whether the cargo storage line 25k corresponding to the current diversion vehicle reader 314k is the last cargo storage line 25n along the conveying direction. If the judgment is yes, the process proceeds to step S2-10; if the judgment is no, the process proceeds to step S2-9a.

[0161] Step S2-10a:

[0162] k=k+1, that is, the next diversion vehicle reader 314k is designated, and then the process returns to step S2-4.

[0163] Step S2-11:

[0164] The entry driving unit 336 drives the hanger 200 to move to the storage receiving blocking unit 335, where the hanger 200 is temporarily stored.

[0165] During the above process, if the number of hangers 200 blocked by the storage and reception blocking portion 335 is excessive, newly arriving hangers 200 will be held up at the entry full load sensor 321, causing the entry full load sensor 321 to sense the hangers 200 and generate a corresponding full load signal. Upon receiving this full load signal, the connection control unit 303 controls the connection blocking portion 331 to block the hangers 200. At this point, no more hangers 200 enter the storage entry circular track 23, and hangers 200 on the connection line 35 are held up. This phenomenon indicates a full load condition and allows the operator to collect and re-enter the hangers 200 at the storage and reception blocking portion 335.

[0166] <Example 2>

[0167] This embodiment provides a warehousing device and a storage system without fixed shelves.

[0168] For the convenience of expression, in the following embodiments, the same symbols are given to the same structures as in the first embodiment, and the same descriptions are omitted.

[0169] In the first embodiment, the diverter vehicle reading unit 313 includes a plurality of diverter vehicle readers 313 i , which are respectively disposed at upstream positions of the storage entry circular track 23 and the respective diverter components 26 i .

[0170] Figure 15 It is a structural block diagram of the warehousing device in an embodiment of the present invention. Figure 16 Schematic diagram of the distribution positions of the vehicle reader and the moving speed acquirer for diversion in an embodiment of the present invention.

[0171] like Figure 15 and Figure 16As shown, compared with the first embodiment, in this embodiment, the diversion vehicle reading unit 313 has only one diversion vehicle reader 3131, which is set at the upstream position of the most upstream diversion component 261, that is, Figure 16 at the same time, in this embodiment, the diversion carrier reading unit 313 also has a moving speed acquirer 314 for acquiring the moving speed of the hanger 200 on the storage entry ring track 23.

[0172] The moving speed acquisition unit 314 includes a photoelectric sensing part and a speed calculation part. The photoelectric sensing part is embedded in the track segment of the storage entry circular track 23, that is, Figure 16 The position indicated by B10 is used to sense the passing bird hook conveyor unit 61. The speed calculation unit calculates the moving speed based on the number of bird hook conveyor units 61 passing per unit time and the spacing between adjacent bird hook conveyor units 61. In this embodiment, since the bird hook conveyor units 61 are closely adjacent to each other, the spacing between adjacent bird hook conveyor units 61 is equal to the length of the bird hook conveyor unit 61.

[0173] The warehousing control unit 301 obtains the corresponding cargo identification information based on the read carrier identification code, determines the cargo storage line 25i that the hanger 200 should enter according to the predetermined cargo warehousing rules, and determines the arrival time of the hanger 200 at the cargo storage line 25i to be entered according to the moving speed, and further controls the diversion component 26i according to the arrival time to connect the corresponding cargo storage line 25i with the storage entry circular track 23, thereby guiding the hanger 200 into the cargo storage line 25i.

[0174] Figure 17 It is a workflow diagram of the goods warehousing process in an embodiment of the present invention.

[0175] like Figure 17 As shown, the workflow of this embodiment includes steps from S3-1 to S3-9, wherein steps S3-1 to S3-3 are consistent with steps S2-1 to S2-3 in embodiment 1, and steps S3-8 to S3-9 are consistent with steps S2-8 to S2-9 in embodiment 1. The consistent steps will not be repeated.

[0176] The workflow of the warehousing process in this embodiment also includes:

[0177] Step S3-4:

[0178] The driving unit 336 drives the hanger 200 to move to the position of the diversion vehicle reader 3131 and the moving speed acquirer 315, and then enters step S3-5.

[0179] Steps S3-5:

[0180] The carrier reader 3131 for diversion reads the carrier identification code of the hanger 200 , and the moving speed acquirer 315 acquires the moving speed of the hanger 200 , and then enters step S3 - 6 .

[0181] Steps S3-6:

[0182] The warehousing control unit 301 obtains the cargo storage line 25i to be entered according to the carrier identification code, and calculates the arrival time of the hanger 200 at the cargo storage line 25i according to the moving speed, and then enters step S3-7.

[0183] Steps S3-7:

[0184] Determine whether the current time is equal to the arrival time. If so, proceed to step S3-8; if not, repeat step S3-7.

[0185] <Example 3>

[0186] This embodiment provides a warehousing device and a storage system without fixed shelves.

[0187] In the first embodiment, the diversion vehicle reading unit 313 has a plurality of diversion vehicle readers 313i, which are respectively arranged at upstream positions of the storage entry circular track 23 and the diversion vehicle readers 313i are used to read the vehicle identification codes of the passing hangers 200.

[0188] Figure 18 It is a structural block diagram of the warehousing device in an embodiment of the present invention. Figure 19 Schematic diagram of the distribution of the diversion vehicle reader and the cargo location reader in an embodiment of the present invention.

[0189] like Figure 18 and Figure 19 As shown, compared with the first embodiment, in this embodiment, the diversion vehicle reading unit 313 has a diversion vehicle reader 3131, which is set at the downstream position of the connection between the storage entry circular track 23 and the connecting line 35, that is, Figure 19 At the position shown in B14, the diversion carrier reading unit 313 also has n+1 cargo location readers for reading the cargo location identification code of the passing bird hook type conveyor unit 61. One of the cargo location readers is set as the binding cargo location reader 315 at the same position as the diversion carrier reader 3131, that is, Figure 19 At the position shown by B14, the remaining n cargo location readers are used as diversion cargo location readers 316i and are respectively set at the upstream positions of the n diversion components 26i.

[0190] Figure 19Only part of the diversion cargo position reader 316i is shown for illustration. According to the conveying direction of the hanger 200, the diversion cargo position reader 3161 is set at the upstream position of the diversion component 261, that is, Figure 19 At the position shown in B10, the diversion cargo position reader 3162 is set at the upstream position of the diversion component 262, that is, Figure 19 At the position shown by B11, and so on.

[0191] 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 warehousing control unit 301 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 clothing in correspondence to realize the binding of the three.

[0192] Subsequently, the warehousing control unit 301 determines the cargo storage line 25i that the hanger 200 should enter based on the carrier identification code of the hanger 200 and the predetermined cargo warehousing rules, and controls the diversion component 26i to connect the corresponding cargo storage line 25i with the storage entry circular track 23 based on the cargo location identification code read by the diversion cargo location reader 316i, thereby guiding the hanger 200 into the corresponding cargo storage line 25i.

[0193] Figure 20 It is a workflow diagram of the goods warehousing process in an embodiment of the present invention.

[0194] like Figure 20 As shown, the goods warehousing process of this embodiment includes steps S4-1 to S4-11 and S4-1 to S4-13, wherein steps S4-1 to S4-11 are basically the same as steps S2-1 to S2-9 in Example 1, and steps S4-1 to S4-13 are basically the same as steps S2-1 to S2-11 in Example 1, so they are not repeated.

[0195] <Example 4>

[0196] This embodiment provides a warehousing device and a storage system without fixed shelves.

[0197] In the first embodiment, the online monitoring sensing unit 324 has two online monitoring sensors 3241 and 3142, which are respectively arranged at the upstream position of the connection between the circular track 22 for warehousing and the two cargo racking lines 21. When the online monitoring sensors 3241 and 3242 do not sense the hanger 200, it means that for the corresponding cargo racking line 21, there is an empty position on the storage entry circular track 23 for the hanger 200 to go online, and the online control unit 302 controls the online blocking part 332 to release the hanger 200.

[0198] Figure 21 It is a structural block diagram of the warehousing device in an embodiment of the present invention. Figure 22 Schematic diagram of the position of the online monitoring sensor in an embodiment of the present invention.

[0199] like Figure 21 and Figure 22 As shown, compared with the first embodiment, in this embodiment, the online monitoring sensing unit 324 has only one online monitoring sensor 3241, which is set at the upstream position of the upstream connection between the circular track 22 for storage and the cargo loading line 21, that is, Figure 22 When the upper line monitoring sensor 3241 does not sense the hanger 200, the upper line control unit 302 sequentially controls each upper line blocking portion 332 to release the hanger 200 according to a predetermined release rule.

[0200] For example, when the online monitoring sensor 324 does not sense the hanger 200, the online control unit 302 controls the hanger 200 to be released one by one onto the circular track 22 for warehousing, starting from the upstream cargo loading line 21. At the same time, the release times of multiple cargo loading lines 21 are all at a certain interval, so that the released hangers are more evenly distributed on the circular track 22 for warehousing.

[0201] <Example 5>

[0202] This embodiment provides a warehousing device and a storage system without fixed shelves.

[0203] In embodiment one, once the full load sensor 321 provided on the storage entry circular track 23 senses the hanger 200, the connection control unit 303 controls the connection blocking part 331 provided on the connection line 35 to block the hanger 200, thereby causing the hanger 200 to stop entering the storage entry circular track 23.

[0204] Figure 23 It is a structural block diagram of the warehousing device in an embodiment of the present invention.

[0205] like Figure 23 As shown, compared to the first embodiment, this embodiment does not include a connecting block on the connecting line 35. Instead, once the full-load sensor 321 detects a hanger 200, the storage control unit 301 controls the storage drive unit 334 to suspend operation, thereby pausing the movement of the format member 222 on the storage circular track 22 and halting the movement of the hanger 200 on the format member 222. In other words, when the storage entry circular track 23 is full, the hangers 200 on the storage circular track 22 pause and are temporarily stored in their original positions.

[0206] Example Function and Effect

[0207] According to an embodiment of the present invention, the warehousing device 110 and the non-fixed shelf storage system 100 include a goods loading line 21, a warehousing circular track 22, a storage entry circular track 23, a connecting line 35, a reading unit 31, a sensing unit 32, an information storage unit 34, and a control unit 30. The reading unit 31 has a carrier identification code reader 311 and a goods identification information reader 312. The control unit 30 has a warehousing control unit 301, an online control unit 302, and a connection control unit 303. Therefore, it can receive a hanger 200 carrying clothes to be loaded into the warehouse, and read the carrier identification code of the hanger 200 and the goods identification information of the clothes. Attribute information, the warehousing control unit 301 can control the information storage unit 34 to store the carrier identification code and the cargo identification information in correspondence, thereby achieving the binding of clothing and hangers 200. Furthermore, the warehousing control unit 301 can assign a cargo storage line 25i to each hanger 200 based on the attribute information and the predetermined cargo warehousing rules, and control the cargo loading line 21, the warehousing circular track 22, the storage entry circular track 23, and the connecting line 35 based on the carrier identification code to transfer the hanger 200 to the assigned cargo storage line 25i. Therefore, the warehousing device 110 of the embodiment of the present invention can automatically classify and warehousing based on the attribute information of the clothing and the predetermined cargo warehousing rules. Because the non-fixed shelf storage system 100 of the embodiment of the present invention adopts a track form for transportation and storage, there is no need to set up fixed shelves or additional transportation equipment, which is easy to build and low cost.

[0208] Furthermore, since an online driving sensor 322 is provided at the connection between the upper line segment 211 and the rising segment 213 of the cargo loading line 21, the online control unit 302 can receive a corresponding signal after the hanger 200 is online and reaches the position, thereby automatically starting the elevator to lift the hanger 200 to the high online buffer segment 212, and the hanger 200 is further put into storage using the circular track 22; since an online full load sensor 323 is provided at the connection between the online buffer segment 212 and the rising segment 213, when the online buffer segment 212 is full and the hanger 200 reaches the position of the online full load sensor 323, the online control unit 302 can receive a corresponding full load signal, thereby pausing the elevator.

[0209] Furthermore, since the upstream connection between the storage circular track 22 and the two cargo loading lines 21 is provided with loading line monitoring sensors 3241 and 3242, respectively, and the loading line buffer sections 212 of the two cargo loading lines 21 are provided with loading line blocking portions 332, when the loading line monitoring sensors 3241 and 3142 do not sense the hanger 200, the loading line control unit 302 controls the corresponding loading line blocking portion 332 to release the hanger 200, allowing the hanger 200 to enter the storage circular track 22. When the loading line monitoring sensors 3241 and 3242 sense the hanger 200, the loading line control unit 302 controls the corresponding loading line blocking portion 332 to block the hanger 200. Therefore, the loading line control unit 302 can automatically adjust the loading speed of the hanger 200 based on the conveying conditions of the storage circular track 22.

[0210] Furthermore, since n diversion components 26i are respectively provided at the connection points between the storage entry circular track 23 and the n cargo storage lines 25i, and corresponding diversion vehicle readers 313i are also provided at the upstream positions of the diversion components 26i, the warehousing control unit 301 can control the diversion components 26i to connect or disconnect the storage entry circular track 23 and the cargo storage line 25i based on the read vehicle identification code and the predetermined cargo warehousing rules, so that the hangers 200 enter the cargo storage line 25i that they should enter, thereby realizing the automatic classification and warehousing of the hangers 200 carrying clothes.

[0211] Since a storage receiving blocking part 335 is also provided on the storage entry circular track 23, an entry full load sensor 321 is provided at the upstream position of the storage receiving blocking part 335, and a connection blocking part 337 is also provided on the connecting line 35, when the entry full load sensor 321 senses the hanger 200, the connection control unit 303 can control the connection blocking part 331 to block the hanger 200 on the connecting line 35, so that the hanger 200 no longer enters the storage entry circular track 23, thereby avoiding too many hangers 200 from being piled on the storage entry circular track 23, affecting the subsequent online storage of hangers 200.

[0212] As described above, the warehousing device 110 of the first embodiment of the present invention can control the process of classifying and warehousing the hangers 200 according to the real-time sensing results of multiple sensors in the sensing unit 32. The entire warehousing process has a high degree of automation, which greatly improves production efficiency and saves manpower.

[0213] In the second embodiment, since the diversion vehicle reading unit 313 has a diversion vehicle reader 3131 and a moving speed acquirer 314, it can obtain the moving speed of the bird hook conveyor unit 61, and calculate the arrival time of the hanger 200 at the cargo storage line 25i that it should enter based on the moving speed. Further, based on the arrival time, the warehousing control unit 301 can control the diversion component 26i to connect to the corresponding cargo storage line 25i, so that the hanger 200 and the clothes on the hanger 200 can be automatically classified and put into storage based on the above-mentioned moving speed, and the warehousing process is smoother.

[0214] In the third embodiment, since the diverter carrier reading unit 313 includes a diverter carrier reader 3131 and n storage location readers, it can read the storage location identification code of the passing bird hook conveyor unit 61, thereby binding the bird hook conveyor unit 61, the garments, and the hangers 200. Furthermore, the storage location identification code is used to automatically control the classified storage of the hangers 200. Hangers 200 hooked on the bird hook conveyor unit 61 may shake during transportation, which may affect the reading of the carrier identification code. In contrast, the bird hook conveyor unit 61 is stably mounted on the storage entry circular track 23. Therefore, the control method based on the storage location identification code is more accurate, reducing malfunctions of the storage device 110 due to misidentification and the need for manual intervention.

[0215] In the fourth embodiment, since the online monitoring sensing unit 324 has an online monitoring sensor 3241 arranged at the upstream position of all cargo racking lines 21, the online control unit 302 releases the hangers 200 on the multiple cargo racking lines 21 in sequence based on the sensing results of the online monitoring sensor 3241 and the predetermined release rules. Therefore, each hanger 200 can be more evenly arranged on the circular track 22 for warehousing, which is more conducive to the subsequent classification and warehousing process of the hangers 200.

[0216] In the fifth embodiment, no connection blocking part 331 is provided on the connecting line 35. Instead, when the storage entry circular track 23 is fully loaded, the warehousing control unit 301 controls the warehousing drive part 334 to suspend operation, so that the hangers 200 on the warehousing circular track 22 no longer enter the storage entry circular track 23. Therefore, the subsequent hangers 200 will not be stacked on the connecting line 35, but will still be relatively evenly distributed on the warehousing circular track 22. Therefore, when the full load condition is released and the transportation continues, the subsequent hangers 200 can pass through the connecting line 35 more evenly and enter the storage entry circular track 23, which can reduce the misoperation caused by the stacking of hangers 200 and also reduce the need for manual intervention.

[0217] 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.

[0218] In the above embodiment, the number of cargo loading lines 21 is two. In actual applications, the number of cargo loading lines 21 may also be one or more.

[0219] In the above embodiment, the number of the cargo storage lines 25 is 100. In actual applications, the number of the cargo storage lines 25 may be less or more.

[0220] In the above embodiment, the upper line drive unit 333 is a hoist installed on the ascending section 213 of the cargo loading line 21. Under the control of the upper line control unit 302, the hoist automatically lifts the hanger 200 to the upper line buffer section 212. In actual applications, the upper line drive unit 333 can also be a manual type. For example, a manual start button is provided on the upper line section 211, allowing the operator to manually activate the hoist by pressing the start button after placing the hanger 200 on the upper line section 211, thereby lifting the hanger 200 to the upper line buffer section 212. In this manual embodiment, a display can also be provided on the upper line section 211 to display the carrier identification code and cargo identification information for the operator to check and confirm.

[0221] In the above embodiment, the operator obtains the carrier identification code and cargo information by using a handheld barcode scanner. In other schemes of the present invention, the carrier identification code and cargo information can also be obtained automatically. For example, the carrier identification code reader and the cargo identification information reader are fixedly installed at the starting position of the upper line segment 211 of the cargo putting line 21 through a bracket, so that the carrier identification code and cargo identification information can be read simultaneously when the hanger 200 is put on the line.
