[0002] At present, the common method of cargo storage is to place the cargo in cargo boxes, then classify the cargo boxes and place them on the corresponding shelves through transportation equipment. Such cargo storage systems have many problems, such as cumbersome shelf construction, high cost of shelves and transportation equipment, and large floor space. In addition, when applied to industries where the cargo is in the form of soft sheets, such as the clothing industry, there are further problems such as multiple pieces of clothing stacked and placed in the cargo box, resulting in wrinkles, and the need to increase the flattening process, which is time-consuming and labor-intensive.

[0003] To solve the above problems, industries with soft sheet-like goods have begun to adopt hanging cargo storage systems, using tracks to transport and store hangers carrying clothing. However, existing hanging cargo storage systems have the following problems: First, it is difficult to adjust the relative positions of multiple hangers after they enter the track in sequence. When hangers are in the wrong position, it is usually necessary to manually remove the hangers from the track for adjustment; second, random conveyor tracks are usually used. After the hangers are stored and enter the track, they are randomly distributed on the track, making it difficult to locate a specific hanger and take it out. When a specific hanger needs to be taken out, it is often necessary to screen multiple hangers on the track, which is very inefficient.

[0004] Therefore, in order to improve the efficiency of warehousing and outbound storage and reduce errors, a cargo storage system that can perform more precise positioning and control is needed. Summary of the invention

[0075] Table 2 Position information table

[0076]

[0077] As shown in Table 2, the bin information table stores the bin number, bin code, and carrier identification code of each bin hole 31111, respectively. The bin number indicates the position of the bin hole 31111 on the storage belt 3111, and the bin numbers are arranged in sequence along the extension direction of the storage belt 3111. In addition, the bin hole 31111 may be hung with a hanger 100 or may be empty, as shown by bin number 2 in Table 2.

[0078] In addition, the information storage unit 52 also stores the position code of the position hole of the predetermined reference position, the number of reference intervals between the reference position and the predetermined insertion position, and the number of reference intervals between the reference position and the predetermined extraction position. The following will be described in detail in conjunction with the corresponding control unit.

[0079] The warehouse management unit 57 manages the information of the warehouse holes, including allocating corresponding warehouse holes 31111 to the hangers 100 according to the attribute information of the clothes when the hangers 100 carrying the clothes are put into storage. Before the hangers 100 carrying the clothes are put into storage, the operator uses a handheld barcode scanner to read the hanger identification code 103 on each hanger 100 to obtain the carrier identification code, and uses the barcode scanner to read the clothing label on the clothes on the hangers 100 to obtain the cargo identification code. The warehouse management unit 57 stores the read carrier identification code and cargo identification code in the cargo information table, thereby binding the hangers 100 and the clothes. Further, the warehouse management unit 57 allocates the corresponding warehouse holes 31111 in the storage device 30 to the hangers 100 according to the cargo attribute information in the cargo information table and the predetermined cargo storage rules, that is, the carrier identification code of the hanger 100 and the warehouse code 31112 of the allocated warehouse hole 31111 are stored in the warehouse information table. Subsequently, upon receiving a storage instruction or a storage-out instruction, the location management unit 57 sends the location code 31112 corresponding to the designated hanger 100 to the location positioning unit 54 .

[0080] In this embodiment, for the convenience of description, it is assumed that the storage location management unit 57 allocates a predetermined storage location hole 31111b to the hanger 100 when the hanger 100 is put into storage. Figure 5 For the location hole at the position shown by B4, the location code 31112 corresponding to the predetermined location hole 31111b is recorded as the predetermined location code 31112b.

[0081] The warehousing control unit 53 controls the process of goods warehousing, and controls the warehousing device 20 to hang the hanger 100 into the storage hole 31111 located at the predetermined hanging position.

[0082] The position positioning unit 54 is used to position the predetermined position hole 31111b when the hanger 100 is hung in or taken out of the predetermined position hole 31111b. The position positioning unit 54 includes a predetermined position code acquisition unit 541, a reference position code acquisition unit 542, a predetermined interval acquisition unit 543, a mobile position acquisition unit 544, and a predetermined position determination unit 545.

[0083] The predetermined bin code acquisition unit 541 obtains the predetermined bin code 31112b of the predetermined bin hole 31111b by searching the bin information table of the information storage unit 52 according to the carrier identification code of the hanger 100. When the receiving unit 2311 receives the hanger 100, the carrier identification code of the hanger 100 is read, and then the predetermined bin code acquisition unit 541 can query and obtain the predetermined bin code 31112b according to the carrier identification code.

[0084] The reference position code acquisition unit 542 is used to acquire the position code 31112 of the position hole 31111 at the predetermined reference position, that is, to use the position hole 31111 as the reference reference. Figure 5 At the position shown by B3, for the convenience of description, the position hole at this position is recorded as the reference position hole 31111a, and the corresponding position code is recorded as the reference position code 31112a.

[0085] The reference position code acquisition unit 542 includes a two-dimensional code reading module 5421 and a two-dimensional code decoding module 5422. In this embodiment, the two-dimensional code reading module 5421 is set Figure 5 The camera at the position shown in B2 in the figure shoots the QR code to obtain an image containing the QR code; then the QR code decoding module 5422 processes and decodes the image to obtain the bin code information contained in the QR code. The reference bin code acquisition unit 542 shoots and reads the reference bin code 31112a at the position when the steel belt storage track 311 is started, that is, before the storage belt 3111 starts to move, so as to obtain the reference bin code 31112a, and stores the reference bin code 31112a in the information storage unit 321.

[0086] The predetermined interval acquisition unit 543 acquires the predetermined interval position d between the predetermined hanging position or the predetermined taking-out position and the predetermined position hole 31111b according to the reference position code 31112a and the predetermined position code 31112b.

[0087] Specifically, taking the scheduled hanging position as an example, the scheduled interval acquisition unit 543 queries the position information table according to the reference position code 31112a to obtain the corresponding position serial number, which is recorded as the reference position i. Similarly, the corresponding position serial number is queried according to the scheduled position code 31112b, which is recorded as the scheduled position x. At the same time, the information storage unit 52 also stores the reference hanging interval D between the scheduled reference position and the scheduled hanging position. The serial number of the position hole 31111 located at the scheduled hanging position is recorded as the hanging position a, and the total number of the position holes 31111 on the storage belt 3111 is recorded as the total number S. Then, the above-mentioned scheduled interval position d can be obtained according to the following formula:

[0088] The pending position a = the base position i + the base pending interval D;

[0089] The interval of the scheduled position d = the pending position a - the scheduled position x.

[0090] In the formula, the predetermined bin spacing d can be a positive number or a negative number. When it is a positive number, the storage belt 3111 moves toward the predetermined conveying direction, and when it is a negative number, the storage belt 3111 moves in the opposite direction.

[0091] Taking the predetermined hanging position as an example, in this embodiment, it is assumed that the hanging reference interval number is 60. At the same time, serial number 0 in Table 2 is used as the reference position hole 31111a, that is, the reference position i = 0, and serial number 20 is used as the predetermined position hole 31111b, that is, the predetermined position x = 20. Therefore, the predetermined position interval = 20 - 0 + 60 = 80. In other words, in order to make the predetermined position hole 31111b reach the predetermined hanging position, the storage belt 3111 needs to move a distance of 80 position holes 31111 in the predetermined conveying direction.

[0092] In addition, in the actual control procedure, in order to achieve a more accurate control effect, the predetermined position interval d is actually calculated according to the following formula:

[0093] The pending position a' = (base position i + base pending interval D + total number S) mod total number S;

[0094] The interval of the scheduled position d = the pending position a - the scheduled position x.

[0095] That is, add the calculated pending position a to the total number S, divide it by the total number S, and take the remainder as the actual pending position a', so as to avoid some edge cases.

[0096] In addition, since there are many bin holes 31111 on the storage belt 3111, it takes a long time to rotate one circle. Therefore, in order to save the conveying time, in the actual control program, the predetermined bin interval d is further processed and calculated:

[0097] When the predetermined position interval d>0:

[0098] It is further determined whether d>S / 2. If it is not, the predetermined bin spacing d remains unchanged. If it is yes, that is, along the predetermined conveying direction (forward direction), the predetermined bin hole 31111b is far from the predetermined hanging position or the predetermined taking-out position, and the reverse direction can reach it faster. Therefore:

[0099] Scheduled position interval d' = Scheduled position interval d – total number S.

[0100] Similarly, when the predetermined position interval d<0:

[0101] It is further determined whether d<-S / 2. If it is not, the predetermined bin spacing d remains unchanged. If it is yes, that is, in the opposite direction (reverse direction) of the predetermined conveying direction, the predetermined bin hole 31111b is far away from the predetermined hanging position or the predetermined taking-out position, and the forward rotation can reach it faster. Therefore:

[0102] The scheduled position interval d' = the scheduled position interval d + the total number S.

[0103] Through the above-mentioned further processing and calculation, the predetermined storage hole 31111b can reach the predetermined hanging position or the predetermined taking-out position more quickly, and some boundary conditions that may cause program errors can be avoided.

[0104] The moving position acquisition unit 544 is used to sense and count the position holes 31111 passing through the predetermined detection position, so as to obtain the moving position number k of the predetermined position hole 31111b, that is, the distance of the predetermined position hole 31111b having moved by how many position holes. The moving position acquisition unit 544 includes a position hole sensing module 5441 and a position hole counting module 5442.

[0105] The storage hole sensing module 5441 is used to sense the storage hole 31111.

[0106] Fig.13 Schematic diagram of the position of the counting sensor in the embodiment of the present invention.

[0107] like Figure 5 and Fig.13 As shown, the bin hole sensing module 5441 includes two counting sensors, which are respectively referred to as a first counting sensor and a second counting sensor. The first counting sensor is arranged at a first detection position, that is, Fig.13 The second counting sensor is arranged at the second detection position, that is, Fig.13 The position shown in B6 in the figure is close to the first detection position and the second detection position, both of which are roughly located at Figure 5 The position shown in B4.

[0108] The first counting sensor and the second counting sensor are arranged at different heights on the storage belt 3111, that is, they have a predetermined distance along the width direction of the storage belt 3111. At the same time, the first counting sensor and the second counting sensor also have a predetermined distance along the extension direction of the storage belt 3111, which is recorded as the detection spacing p. In this embodiment, the detection spacing p = 13.5 mm.

[0109] In addition, the first counting sensor and the second counting sensor are both infrared photoelectric sensors with a sensing diameter of 0.5mm-2mm. The infrared photoelectric sensor generates different levels when sensing the steel belt portion and the storage hole 31111. Therefore, once a storage hole 31111 passes the detection position, the infrared photoelectric sensor undergoes a level jump and generates a corresponding electrical signal.

[0110] Specifically, the infrared photoelectric sensor generates a falling edge signal that jumps from a high level to a low level when sensing movement from the steel strip part to the storage hole part, and generates a rising edge signal that jumps from a low level to a high level when sensing movement from the storage hole part to the steel strip part.

[0111] The position hole counting module 5442 counts according to the sensing result of the position hole sensing module 5441, thereby obtaining the number of movable positions k. The position hole counting module 5442 counts once only when it receives the electrical signals generated by two counting sensors, and the electrical signals of the two counting sensors are different (i.e., one is a rising edge signal and the other is a falling edge signal).

[0112] Specifically, in this embodiment, the first counting sensor is mainly used, and the second counting sensor is auxiliary. The position hole counting module 5442 triggers the counting judgment when the first counting sensor senses a falling edge signal, and judges whether the second counting sensor senses a rising edge signal. When the judgment is yes, that is, when the two counting sensors sense different electrical signals, the position hole counting module 5442 performs a count and updates the number of moving positions k accordingly. When the storage belt 31 moves along the predetermined conveying direction, the number of moving positions k + 1 is moved, and when the storage belt 31 moves in the opposite direction, the number of moving positions k – 1 is moved.

[0113] In addition, in the actual program implementation, in order to prevent miscounting, further detection and judgment are performed:

[0114] Every 3ms, it is judged whether the received electrical signal is a falling edge signal and a rising edge signal, and the judgment is performed three times. Only when all three judgments are yes, a count is performed.

[0115] In addition, after one count, the time t required for the storage belt 3111 to move through the interval l between two adjacent storage holes 31111 is calculated according to the current moving speed v of the storage belt 31, that is:

[0116] Time t = interval between adjacent position holes l / current moving speed v.

[0117] Subsequently, within the time t, even if the two counting sensors sense the rising edge signal and the falling edge signal, no counting is performed.

[0118] Through the counting method in this embodiment, it is possible to avoid miscounting in various interference situations, thereby obtaining an accurate counting result, that is, obtaining an accurate number k of mobile bins.

[0119] Interference situations generally include:

[0120] The bin holes 31111 on the storage belt 3111 vibrate due to external forces such as wind;

[0121] The garments stored on the storage belt 3111 have hats, and the hats cover part of the storage holes 31111 during the conveying process;

[0122] The passing of operators, conveying equipment, etc. causes the illumination of some locations on the storage belt 3111 to change.

[0123] The reserved position determination unit 545 determines whether the reserved position hole 31111b has reached the predetermined hanging position or the predetermined taking-out position according to the reserved position interval obtained by the reserved interval acquisition unit 543 and the number of moving positions obtained by the moving position acquisition unit 544, that is, determines whether the reserved position interval d = the number of moving positions k.

[0124] In the actual control program, in order to facilitate the program implementation, the base position i is actually updated in real time according to the number of moving positions k, that is:

[0125] Base position i' = base position i + number of moving positions k.

[0126] Then, the scheduled position interval d is updated in real time according to the updated reference position i', and the scheduled position determination unit 545 actually detects whether the scheduled position interval d is 0. If it is detected that the scheduled position interval d = 0, it is determined that the scheduled position hole 31111b has reached the scheduled hanging position or the scheduled taking-out position.

[0127] When the judgment is no, the scheduled position determination unit 545 further obtains the number of positions between the scheduled position hole 31111b and the scheduled hanging position or the scheduled taking-out position, that is, the number of positions that the scheduled position hole 31111b needs to move further, recorded as the current interval b, that is:

[0128] Current interval b = scheduled position interval d – number of moving positions k.

[0129] In the actual control procedure, since the reference position i' and the predetermined position interval d are updated in real time according to the number of moving positions k, the current interval b is the real-time predetermined position interval d.

[0130] The storage control unit 55 controls the storage belt driving mechanism 312 according to the positioning result of the storage position positioning unit 54. The storage belt driving mechanism 312 drives the storage belt 3111 to move, stop or decelerate, so as to accurately move the predetermined storage position hole 31111b to the predetermined hanging position or the predetermined removal position. Specifically, for the predetermined hanging position:

[0131] When the predetermined storage position determination unit 544 determines that the storage belt 3111 has not been reached and the insertion interval is ≥ 20 storage position holes 31111, the storage control unit 55 drives the storage belt 3111 to move at a predetermined high speed. In this embodiment, the predetermined high speed is 18m / min-28m / min;

[0132] When the predetermined position determination unit 544 determines that the position has not been reached, and 5 position holes 31111 ≤ the hanging interval < 20 position holes 31111, the storage control unit 55 drives the storage belt 3111 to move at a predetermined medium speed. In this embodiment, the predetermined medium speed is 12 m / min.

[0133] When the predetermined storage position determination unit 544 determines that the storage belt 3111 has not been reached and the insertion interval is less than 5 storage position holes 31111, the storage control unit 55 drives the storage belt 3111 to move at a predetermined low speed. In this embodiment, the predetermined low speed is 6 m / min.

[0134] When the predetermined storage position determination unit 544 determines that the predetermined hanging position has been reached, the storage control unit 55 controls the driving mechanism 312 to stop working, so that the storage belt 3111 is stationary. At this time, the hanging mechanism 231 can hang the hanger 100 into the storage position hole 31111 located at the predetermined hanging position.

[0135] Likewise, for the scheduled take-out location:

[0136] When the predetermined position determination unit 544 determines that the storage belt 3111 has not been reached and the removal interval is ≥ 20 position holes 31111, the storage control unit 55 drives the storage belt 3111 to move at a predetermined high speed. In this embodiment, the predetermined high speed is 18m / min-28m / min;

[0137] When the predetermined position determination unit 544 determines that the storage belt 3111 has not arrived and 5 position holes 31111 ≤ the removal interval < 20 position holes 31111, the storage control unit 55 drives the storage belt 3111 to move at a predetermined medium speed. In this embodiment, the predetermined medium speed is 12 m / min.

[0138] When the predetermined position determination unit 544 determines that the storage belt 3111 has not been reached and the removal interval is less than 5 position holes 31111, the storage control unit 55 drives the storage belt 3111 to move at a predetermined low speed. In this embodiment, the predetermined low speed is 6 m / min.

[0139] When the predetermined bin position determination unit 544 determines that the predetermined removal position has been reached, the storage control unit 55 drives the storage belt 3111 to maintain a predetermined low-speed movement. At this time, the bin removal device 41 can remove the hanger 100 from the bin hole 31111 located at the predetermined removal position.

[0140] The outbound control unit 56 controls the process of goods outbound, and controls the outbound equipment 40 to take out the hanger 100 from the storage hole 31111 located at a predetermined taking-out position.

[0141] In addition, in this embodiment, the above-mentioned information storage unit 52 and warehouse management unit 57 are arranged in a management end device (such as a local server or a cloud server), and the warehousing control unit 53, the warehouse positioning unit 54, the storage control unit 55 and the outbound control unit 56 are arranged in a control end device (such as an industrial computer).

[0142] Fig.14 It is a workflow diagram for positioning a predetermined bin hole in an embodiment of the present invention.

[0143] like Fig.14 As shown, in this embodiment, the workflow for positioning the predetermined position hole 31111b specifically includes the following steps:

[0144] Step S1-1, the reserved storage location acquisition unit 541 queries the storage location information table according to the vehicle identification code, obtains the corresponding reserved storage location code 31112b, and then proceeds to step S1-2;

[0145] Step S1-2, the scheduled interval acquisition unit 543 acquires the scheduled location interval d according to the reference location code 31112a and the scheduled location code 31112b, and then proceeds to step S1-3;

[0146] Step S1-3, the storage control unit 55 controls the storage belt driving mechanism 312 according to the predetermined bin spacing d, drives the storage belt 3111 to move at a predetermined speed, and then enters step S1-4;

[0147] Step S1-4, the mobile position acquisition unit 544 acquires the number k of mobile positions of the predetermined position hole 31111b, and then proceeds to step S1-5;

[0148] Step S1-5, the predetermined position determination unit 545 determines whether the predetermined position hole 31111b has reached the predetermined insertion position or the predetermined removal position, and returns to step S1-4 when it is determined that it has not reached the predetermined insertion position, and enters step S1-6 when it is determined that it has reached the predetermined insertion position, and enters step S1-7 when it is determined that it has reached the predetermined removal position;

[0149] Step S1-6, the storage control unit 55 controls the storage belt driving mechanism 312 to stop working, so that the storage belt 31 is stationary, and then enters the end state;

[0150] In step S1-7, the storage control unit 55 controls the storage belt driving mechanism 312 to drive the storage belt 31 to move at a predetermined low speed, and then enters the end state.

[0151] Prior to the above steps, when the system is started, the reference location code acquisition unit 542 has acquired the location code 31112 at the predetermined reference position as the reference location code 31112a.

[0152] In the above steps, the storage belt 3111 moves at the above-mentioned predetermined high speed, medium speed or low speed.

[0153] Fig.15 1 is a flowchart of the process of hanging a clothes hanger into a storage belt in an embodiment of the present invention.

[0154] like Fig.15 As shown, in this embodiment, the workflow of hanging the hanger 100 on the storage belt 3111 specifically includes the following steps:

[0155] Step S2-1, the staff holds a barcode scanner to read the carrier identification code of the hanger 100 to be stored and the cargo identification code of the clothing, and then proceeds to step S2-2;

[0156] Step S2-2, the staff hangs the hanger 100 on the upper shelf storage track 211, and the hanger 100 slides to the blocking device 22, and then enters step S2-3;

[0157] Step S2-3, the storage location management unit 57 allocates a predetermined storage location hole 31111b to the hanger 100 according to the attribute information of the clothing and the predetermined storage rules, that is, sets a corresponding predetermined storage location code 31112b for the hanger 100, and sends the predetermined storage location code 31112b to the storage location positioning unit 54, and then enters step S2-4;

[0158] Step S2-4, the storage control unit 55 moves the predetermined storage hole 31111b to the predetermined hanging position according to the positioning result of the storage position positioning unit 54, and makes the storage belt 3111 still, and then enters step S2-5;

[0159] Step S2-5, the storage control unit 53 controls the blocking device 22 to release the hanger 100, and the hanger 100 slides to the hanging mechanism 231 and is hooked by the hanging mechanism 231, and then enters step S2-6;

[0160] Step S2-6, the storage control unit 53 controls the hanging mechanism 231 to move the hanger 100 to a predetermined hanging position, and then enters step S2-7;

[0161] Step S2-7, the warehousing control unit 53 controls the hanging mechanism 231 to hang the hanger 100 into the predetermined storage hole 31111b, and then enters the end state.

[0162] In the above steps, for the sake of clarity and convenience, steps S2-5 and S2-6 are executed to release and transfer the hanger 100 only after the predetermined storage hole 31111b reaches the predetermined hanging position in step S2-4. In fact, step S2-4 and steps S2-5 to S2-6 can be performed simultaneously, thereby saving the time for warehousing the hanger 100.

[0163] Fig.16 1 is a flowchart of taking out a hanger from a storage belt in an embodiment of the present invention.

[0164] like Fig.16 As shown, based on the above-mentioned outbound device 40, storage device 30 and warehouse control device 50, in this embodiment, the workflow of taking out the hanger 100 from the storage belt 3111 specifically includes the following steps:

[0165] Step S3-1, the staff inputs the cargo identification code of the clothing to be taken out through the operation terminal, and then proceeds to step S3-2;

[0166] Step S3-2, the storage location management unit 57 obtains the corresponding carrier identification code of the hanger 100 according to the cargo identification code, and then obtains the corresponding reserved storage location code 31112b of the reserved storage location hole 31111b according to the carrier identification code, and sends the reserved storage location code 31112b to the storage location positioning unit 54, and then enters step S3-3;

[0167] Step 3-3, the storage control unit 55 moves the predetermined position hole 31111b to the predetermined removal position according to the positioning result of the position positioning unit 54, and makes the storage belt 3111 keep moving at a predetermined low speed, and then enters step S3-4;

[0168] Step S3-4, the outbound control unit 56 controls the outbound device 41 to pick out the hanger 100 from the predetermined storage hole 31111b, and then enters step S3-5;

[0169] Step S3-5, the outbound control unit 56 controls the offline device 42 to transfer the hanger 100 to the outbound inclined rail 422, and the hanger 100 is temporarily stored at the end of the outbound inclined rail 422, and then enters the end state.

[0170] As described above, through the storage control device 50 and the belt storage system 10 of this embodiment, the predetermined storage hole 31111b can be accurately positioned to the predetermined hanging position or the predetermined removal position, and then the warehousing equipment 20 can accurately hang the hanger 100 into the predetermined storage hole 31111b, or the out-of-warehouse equipment 40 can accurately remove the hanger 100 from the predetermined storage hole 31111b.

[0171] Example Function and Effect

[0172] According to the storage control device 50 and the belt storage system 10 provided in this embodiment, the storage control device 50 includes a storage location positioning unit 54 and a storage control unit 55. Since the storage location positioning unit 54 has a predetermined storage location code acquisition unit 541, it is possible to acquire the storage location code of the predetermined predetermined storage location hole 31111b, recorded as the predetermined storage location code 31112b; since it has a reference storage location code acquisition unit 542, it is possible to acquire the storage location code at the predetermined reference position as the reference storage location code 31112a; since it has a predetermined interval acquisition unit 543, it is possible to acquire the predetermined storage location interval between the predetermined hanging position or the predetermined taking-out position and the predetermined storage location hole 31111b according to the reference storage location code 31112a and the predetermined storage location code 31112b; since it has a mobile storage location acquisition unit 544, it is possible It is capable of sensing and counting the position holes 31111 passing through the predetermined detection position, and obtaining the number of moving positions that the predetermined position hole 31111b has moved; since it has a predetermined position determination unit 545, it is capable of judging whether the predetermined position hole 31111b has reached the predetermined hanging position or the predetermined taking-out position according to the obtained predetermined position interval and the number of moving positions; and since it has a storage control unit 55, it is capable of driving the storage belt driving mechanism 312 according to the positioning result of the position positioning unit 54, driving the storage belt 311 to move, stop or decelerate, and driving the predetermined position hole 31111b to accurately reach the predetermined hanging position or the predetermined taking-out position, so that the hanger 100 can be accurately hung in the predetermined position hole 31111b or taken out from the predetermined position hole 31111b, with accurate positioning and a high degree of automation.

[0173] Furthermore, the position code 31112 is a two-dimensional code. Accordingly, the reference position code acquisition unit 541 includes a camera and a two-dimensional code decoding module 5412 arranged at a predetermined reference position next to the storage belt 311. Therefore, the two-dimensional code at the position can be photographed to obtain an image containing the two-dimensional code, and then decoded to obtain the position code information contained in the two-dimensional code. The mobile position acquisition unit 543 includes a position hole sensing module 5431 and a position hole counting module 5432 arranged at a predetermined detection position next to the storage belt 311. The position hole sensing module 5431 is an infrared photoelectric sensor, so it can sense and count the position holes 31111 passing through the position. The reference position code acquisition unit 541 and the mobile position acquisition unit 543 of this embodiment both adopt non-contact reading and sensing methods, so they do not affect the movement of the storage belt 3111 and the transportation of the hanger 100. The non-contact method also increases the service life of related equipment. At the same time, the reference location code acquisition unit 541 and the mobile location acquisition unit 543 of this embodiment are both arranged outside the warehousing equipment 20 and the outbound equipment 40, so they do not affect the operation of the warehousing equipment 20 and the outbound equipment 40, and are also more convenient for inspection and maintenance.

[0174] Furthermore, the storage control unit 55 can control the storage belt driving mechanism 312 to stop working and make the storage belt 311 stationary when the predetermined position determination unit 545 determines that the predetermined position hole 31111b has reached the predetermined hanging position. At this time, the warehousing equipment 20 can accurately hang the hanger 100 into the predetermined position hole 31111b under the control of the warehousing control unit 53; similarly, the storage control unit 55 can control the storage belt driving mechanism 312 to slow down when the predetermined position determination unit 544 determines that the predetermined position hole 31111b has reached the predetermined removal position. The storage belt 311 is decelerated to a predetermined out-of-warehouse speed. At this time, the out-of-warehouse device 41 can accurately pick out the hanger 100 from the predetermined position hole 31111b under the control of the out-of-warehouse control unit 56. In addition, the storage control unit 55 can also control the driving mechanism 312 according to the hanging interval or the taking-out interval obtained by the predetermined position determination unit 544, and drive the storage belt 3111 to move at a corresponding conveying speed, so that when the predetermined position hole 31111b gradually approaches the predetermined hanging position or the predetermined taking-out position, the storage belt 3111 can gradually slow down, so that the positioning of the position hole 31111 is more accurate.

[0175] The above embodiments are only used to illustrate specific implementation modes of the present invention, and the present invention is not limited to the description scope of the above embodiments.

[0176] In the above embodiment, the distance between two adjacent storage holes 31111 is 26.52 mm. In other embodiments of the present invention, the distance between two adjacent storage holes 31111 can also be set to 15 mm-30 mm according to the style and size of the clothes to be hung.

[0177] In the above embodiment, the warehouse code 31112 is a two-dimensional code. Accordingly, the reference warehouse code acquisition unit 542 includes a camera for photographing the two-dimensional code. In other schemes of the present invention, the warehouse code 31112 may also be other types of identification codes, and the reference warehouse code acquisition unit 542 adopts other corresponding contactless readers.

[0178] In the above embodiment, the location code 31112 corresponds to the location hole 31111 one to one. In other schemes of the present invention, the location code 31112 and the location hole 31111 may also correspond to each other at intervals. For example, every 10 location holes 31111 correspond to one location code 31112. When the system starts, the staff manually adjusts and moves one of the location codes 31112 to the reference position, which can also achieve the technical effect of the present invention.

[0179] In the above embodiment, the warehouse information table stores the warehouse serial number and warehouse code 31112 of each warehouse hole 31111. In other schemes of the present invention, the warehouse code 31112 can also be directly the warehouse serial number, that is, there is no warehouse number column in the warehouse information table.

[0180] In the above embodiment, the information storage unit 52 stores the number of hanging reference intervals between the reference position and the predetermined hanging position, and stores the number of retrieval reference intervals between the reference position and the predetermined retrieval position.
