The hanger 100 includes a hook portion 101 at the top, a shoulder portion 102 at the bottom for hanging clothes, and a transition portion 103 between the hook portion 101 and the shoulder portion 102. The hook portion 101 has a hanging opening 101a, and the transition portion 103 is provided with a hanger identification code 1031. When the hanger 100 is hung in the storage hole 311, the inner top of the hook portion 101 just contacts the bottom of the storage hole 311.

[0047] Usually, the distance d1 between the center lines of two adjacent storage holes 311 is set to be slightly larger than the width formed by the front and rear sides when the clothes are hung on the hanger, so that each storage hole 311 can hang clothes. In this embodiment, d1 = 26.52mm. In addition, in this embodiment, the design load-bearing capacity of each storage hole 311 is about 2.5kg (the weight of the hanger + clothing). A plurality of storage codes 312 are also provided on the storage belt 31, which are used to uniquely identify the corresponding storage hole 311 in the current system. The storage code 312 corresponds to the storage hole 311 one by one and is set on the steel belt above the storage hole 311. The storage code 312 of this embodiment is a two-dimensional code.

[0048] Figure 4 It is a structural diagram of the warehousing equipment in an embodiment of the present invention.

[0049] like Figure 4 As shown, the warehousing equipment 20 includes an online device 21, a blocking device 22 and a warehouse entry device 23.

[0050] The clothing hanger 100 is put on the line by the device 21, and comprises a storage rail 211 for hanging the clothing hanger 100, a hoist 212 for lifting the clothing hanger 100, a lifting rail 213 and a sliding ramp 214. After the clothing hanger 100 is hung on the storage rail 211, it slides to the hoist 212 by gravity, enters the sliding ramp 214 after being lifted by the hoist 212, and slides down along the sliding ramp 214 by gravity. A stop device 22 is provided near the end of the sliding ramp 214.

[0051] The blocking device 22 releases the hangers 100 one by one. After being released, the hangers 100 arrive at the warehouse entering device 23 and are hooked by the warehouse entering device 23.

[0052] The storage device 23 hangs the hanger 100 into the corresponding predetermined storage hole. The storage device 23 has a hanging mechanism 231 for receiving the hanger 100 and hanging the hanger 100 on the storage belt 31 and a pushing mechanism 232 for pushing away the clothes on the storage belt 31.

[0053] The hanging mechanism 231 includes a receiving unit 2311, a moving unit 2312 and a rotating unit 2313. The receiving unit 2311 is provided with an RFID reader, so that the released hanger 100 can be received and made stationary, so that the rotating unit 2313 can hook the hanger 100, and at the same time, the receiving unit 2311 can read the carrier identification code of the hanger 100. The rotating unit 2313 includes a mechanical arm that can rotate in the horizontal direction and a movable hook installed at the end of the mechanical arm, so that the rotating unit 2313 can hook the hanger 100 and drive the hanger 100 to rotate so that the hanging opening 101a faces the storage hole 311. The moving unit 2312 can drive the rotating unit 2313 to move horizontally, so that the rotating unit 2313 moves to the blocking device 22 to receive the hanger 100, and can move the rotating unit 2313 to the storage belt 31 to hang the hanger 100.

[0054] The pushing mechanism 232 is used to push the clothes located on both sides of the storage hole 311 toward both sides, so that the hanging mechanism 231 can be hung on the hanger 100 smoothly.

[0055] After the storage device 20 stores the hanger 100 in the storage device 30, the storage device 30 stores and manages the hanger 100. The storage device 30 includes a pre-storage belt storage device 32, a first storage belt storage device 33, a second storage belt storage device 34 and a transfer device 35.

[0056] The pre-storage belt storage device 32 is used to store the reserved clothing to be taken in the near future. In this embodiment, the storage control device 50 stores the pre-recorded reservation information.

[0057] Figure 5 1 is a structural diagram of a tape storage device for reservation in an embodiment of the present invention. Figure 6 1 is a structural diagram of a tape storage device for reservation at different angles according to an embodiment of the present invention. Figure 7 It is an orthographic projection diagram of the tape storage device for reservation in the embodiment of the present invention.

[0058] like Figure 5-7 As shown, the reservation belt storage device 32 includes a reservation steel belt storage rail 321 and a reservation drive mechanism 322 .

[0059] The steel belt storage track 321 for reservation is a closed circular track, including a mounting track 3211 and a storage belt 31. The mounting track 3211 is fixedly installed at a predetermined position by a metal bracket, and the storage belt 31 is movably installed on the mounting track 3211. In this embodiment, the storage belt 31 of the pre-storage belt storage device 32 is recorded as the reservation storage belt 31a. The reservation storage belt 31a is a flat circular track. At the same time, the reservation storage belt 31a is set at a position convenient for taking clothes, 1.5m-1.6m from the ground, and there is no obstruction around. Therefore, in addition to taking out the hanger 100 on the reservation storage belt 31a through the outbound device 40 set on the pre-storage belt storage device 32, the staff or customers can also walk to the position of the reservation storage belt 31a and directly take the hanger 100 from the reservation storage belt 31a by hand.

[0060] The reservation driving mechanism 322 is used to drive the reservation storage belt 31a to move.

[0061] Figure 8 4 is a structural diagram of a storage tape in an embodiment of the present invention.

[0062] Fig. 9 1 is a structural diagram of storage bands at different angles in an embodiment of the present invention.

[0063] like Figure 5-9 As shown, the reservation driving mechanism 322 includes a driving motor 3221, a driving gear 3222, a plurality of drag reduction wheels 3223 and a plurality of limit wheels 3224. A plurality of driving holes 313 are provided on the storage belt 31, wherein the plurality of driving holes 313 located at the driving gear 3222 are respectively meshed with a plurality of teeth of the driving gear 3222, and the plurality of drag reduction wheels 3223 and the plurality of limit wheels 3224 are installed on the storage belt 31 at intervals and their wheel bodies are movably engaged in the mounting rail 3211. The driving motor 3221 drives the driving gear 3222 to rotate, and drives the storage belt 311 to move along the extension direction of the mounting rail 3211 through a meshing transmission mode, which is a prior art and will not be described in detail.

[0064] Fig.10 It is a structural diagram of a first belt storage device for warehousing in an embodiment of the present invention.

[0065] Fig.11 It is an orthographic projection diagram of the first belt storage device for warehousing in an embodiment of the present invention.

[0066] like Fig.10 and Fig.11As shown, the first storage belt storage device 33 is used to store hangers 100 carrying clothes, including a first storage belt 31b and a first storage driving mechanism 332 for driving the first storage belt 31b to move. Its structure is consistent with the pre-storage belt storage device 32, so it is not repeated here.

[0067] like Figure 2 and Fig.10 As shown, the first storage belt 31b is also a planar annular track, and the pre-storage belt storage device 32 and the first storage belt storage device 33 are stacked, with the pre-storage belt storage device 32 being arranged at the bottom and the first storage belt storage device 33 being arranged at the top.

[0068] like Figure 2 As shown, the second storage belt storage device 34 is a spiral belt storage device, which can be used to store clothes that are not used for a long time, or to store a variety of clothes in a mixed manner, etc. Although the storage belt 31 of the second storage belt storage device 34 is wound into a spiral shape, it is still a single closed track. Therefore, the structure of the second storage belt storage device 33 is substantially the same as that of the pre-storage belt storage device 32, and will not be repeated here.

[0069] The transfer device 35 is used to transfer the hangers 100 between different belt storage devices, and includes a transfer mechanism 351 for transferring the hangers 100 in a horizontal direction, and a deployment mechanism 352 for transferring the hangers 100 in a vertical direction.

[0070] Fig.12 1 is a structural diagram of a transfer mechanism in an embodiment of the present invention.

[0071] like Figure 2 and Fig.12 As shown, the transfer mechanism 351 is arranged between the pre-storage belt storage device 32 and the second storage belt storage device 34, and includes a transfer and placement unit 3511, a transfer rotation unit 3512 and a transfer translation unit 3513.

[0072] The transfer and placement unit 3511 has a movable gripper and a servo that drives the gripper to grasp and place. The movable gripper matches the hook portion 101 of the hanger 100, so that the movable gripper can grasp the hanger 100 and take the hanger 100 out of the storage hole 311, and can release the hanger 100 at a position corresponding to the storage hole 311, so that the hanger 100 is hooked into the storage hole 311.

[0073] The transfer rotation unit 3512 is used to drive the transfer pick-up and place unit 3511 to rotate in the horizontal direction, so that the hanging opening 101a of the hanger 100 faces the storage belt 31 on the other side, so as to facilitate hanging. The transfer rotation unit 3512 is fixedly installed at the end of the transfer rotation unit 3512, and its specific structure is consistent with the rotation unit 2313, so it is not repeated.

[0074] The transfer translation unit 3513 is used to drive the transfer pick-and-place unit 3511 to move in the horizontal direction, and includes a horizontal drive motor, a horizontal drive gear installed at the output end of the horizontal drive motor, a drive rack, a guide rail extending in the horizontal direction, etc. The specific structure is prior art and will not be described in detail. One end of the transfer translation unit 3513 is arranged near the pre-storage belt storage device 32, and the other end is arranged near the second storage belt storage device 34.

[0075] Fig.13 It is a structural diagram of the deployment mechanism in an embodiment of the present invention.

[0076] like Figure 2 and Fig.13 As shown, the allocation mechanism 352 is arranged near the stacked pre-storage belt storage device 32 and the first warehousing belt storage device 33, and includes an allocation and placement unit 3521 and an allocation vertical movement unit 3522.

[0077] The deployment and retrieval unit 3521 has a movable gripper, which is arranged to face the pre-storage belt storage device 32 and the first storage belt storage device 33. The structure and function of the deployment and retrieval unit 3521 are consistent with those of the transfer and retrieval unit 3511, so they are not described again.

[0078] The vertical shift unit 3522 is used to drive the picking and placing unit 3521 to move in the vertical direction, including a vertical drive motor, a vertical synchronous pulley installed at the output end of the vertical drive motor, a synchronous belt extending in the vertical direction, and a guide rail extending in the vertical direction. Its specific structure is the existing technology and will not be described in detail.

[0079] Although the transfer mechanism 351 and the allocation mechanism 352 transfer the hanger 100 in different directions, their principles are the same, that is, the hanger 100 is taken out from the storage hole 311 of one storage belt 31, the hanger 100 is translated to another storage belt 31, and then the hanger 100 is hung in the storage hole 311 of another storage belt 31. Therefore, the following will only take the reservation belt storage device 32, the first storage belt storage device 33 and the allocation mechanism 352 as examples for description.

[0080] The allocation mechanism 352 is arranged beside the stacked reservation tape storage device 32 and the first storage tape storage device 33. The position of the reservation storage tape 31a corresponding to the allocation mechanism 352 is the predetermined reservation hanging position, that is, Figure 7 The position shown in B1 in the figure, the position corresponding to the first storage belt 31b and the allocation mechanism 352 is the predetermined storage and retrieval position, that is, Fig.11 The position shown by B4, that is, the appointment hanging position and the storage retrieval position are in the same vertical direction.

[0081] Under the control of the storage control device 50, the first storage belt storage device 33 rotates the storage hole 311 with the hanger 100 to be taken out to the storage retrieval position, and then makes the first storage storage belt 31b stationary. At the same time, the reservation belt storage device 32 rotates an empty storage hole 311 to the reservation hanging position, and then makes the reservation storage belt 31a stationary. Then, the allocation mechanism 352 takes out the hanger 100 from the storage hole 311 at the storage retrieval position, translates the hanger 100 to the reservation storage belt 31a in the vertical direction, and hangs the hanger 100 in the storage hole 311 at the reservation hanging position. The storage control device 50 and the control logic will be described in detail later.

[0082] The outbound device 40 is used to outbound the hangers 100 .

[0083] Fig.14 It is a structural diagram of the outbound device in an embodiment of the present invention.

[0084] like Fig.14 As shown, the outbound device 40 includes an outbound device 41 and an offline device 42. The outbound device 41 is used to move the hangers 100 on the storage belt 31 out of the bin hole 311, and the offline device 42 is used to offline or store the hangers 100 from the outbound device 41.

[0085] The offline device 42 has a lifting mechanism 421 and a storage ramp 422. The lifting mechanism 421 includes a lifting track 4211 connecting the storage device 41 and the storage ramp 422, and a storage lift 4212 for transporting the hanger 100 along the lifting track 4211 to the storage ramp 422.

[0086] Fig.15 It is a structural diagram of the warehouse discharge device in an embodiment of the present invention.

[0087] Fig.16 It is a partial structural diagram of the full-name warehouse discharge device implemented in the present invention.

[0088] like Fig.15 and Fig.16As shown, the outgoing device 41 includes a guide transfer mechanism 411 and a lever mechanism 412. The guide transfer mechanism 411 is used to guide and transfer the hangers 100 on the storage belt 31 to the lifting track 4211 of the offline device 42, and the lever mechanism 412 is used to push the hangers 100 guided out by the guide transfer mechanism 411.

[0089] The guide transfer mechanism 411 includes a curved rail member 4111, a guide member 4112, and a guide motor 4113. The guide member 4112 is used to transfer the hanger 100 located on the storage belt 31 to the curved rail member 4111, and the guide motor 4113 is used to drive the guide member 4112 to rotate. In addition, the position where the guide member 4112 is set is the predetermined removal position, that is, Figure 5 At the position shown in B2.

[0090] like Fig.16 As shown, the middle part of the guide member 4112 has a passage for the storage belt 31 to pass through, and the guide member 4112 also has an introduction end 4112a and an extraction end 4112b, the introduction end 4112a is used to introduce the hanger 100 from the storage belt 31 to the guide member 4112, and the extraction end 4112b is used to extract the hanger 100 from the guide member 4112 to the curved track member 4111. The position on the storage belt 31 corresponding to the guide member 411 is the predetermined out-of-warehouse extraction position.

[0091] In the initial state, the guide member 4112 is in a horizontal position relative to the storage belt 31, that is, the length direction of the guide member 4112 is roughly parallel to the extension direction of the storage belt 31; when the hanger 100 is to be taken out, the guide member 4112 is driven by the guide motor 4113 to rotate upward to a position matching with the curved rail member 4111, that is, Fig.16 At this time, the hanger 100 is lifted up obliquely, leaves the storage hole 311, and then enters the curved track member 4111 along the guide member 4112, and is then pushed and moved by the lever mechanism 412.

[0092] The lever mechanism 412 includes a plurality of levers 4121, a turntable 4122, and a turntable motor 4123. The plurality of levers 4121 are evenly spaced and installed on the side of the turntable 4122. Driven by the turntable motor 4123, the turntable 4122 rotates, driving the levers 4121 to move along an arc, thereby pushing the hanger 100 on the curved track member 4111 to move along the extension direction of the curved track member 4111 to the offline device 42, and then the offline device 42 moves the hanger 100 to the end of the outgoing ramp 422 for temporary storage.

[0093] The storage control device 50 controls the operation of the above-mentioned storage device 20, storage device 30 and storage device 40. Figure 1As shown, the warehouse control device 50 includes a general control unit 501, a cargo information storage unit 502, a warehouse location information storage unit 503, a reservation information storage unit 504, a warehousing control unit 505, a first warehouse positioning control unit 506, a second warehouse positioning control unit 507, a reservation positioning control unit 508, a transfer control unit 509, a reservation control unit 510 and a warehouse outgoing control unit 511.

[0094] The cargo information storage unit 502 stores a cargo information table.

[0095] Table 1 Cargo Information

[0096]

[0097] As shown in Table 1, the cargo information table stores the carrier identification code of each hanger 100, the cargo identification code of the clothing on the hanger 100, and various attribute information of the clothing.

[0098] The location information storage unit 503 stores a location information table.

[0099] Table 2 Position information table

[0100]

[0101]

[0102] As shown in Table 2, the bin information table stores the bin serial number, bin code 312 of each bin 311 on each storage belt 31, and the carrier identification code of the hanger 100 hung in the bin hole 311. The bin serial number indicates the position of the bin hole 311 on the storage belt 31, and the bin serial numbers are arranged in sequence along the extension direction of the storage belt 31. In addition, the bin hole 311 can be hung with a hanger 100 or be empty, as shown by the bin code CW1002 in Table 2.

[0103] The reservation information storage unit 504 stores a reservation information table, which contains information on hangers 100 and clothing that are reserved by customers and need to be taken out in the near future.

[0104] Table 3 Reservation information table

[0105]

[0106] As shown in Table 3, the reservation information table stores the carrier identification code of each hanger 100 to be taken out at a specified time, the cargo identification code of the clothing on the hanger 100 and the scheduled taking-out time.

[0107] The warehouse management unit 512 allocates and manages the information of the warehouse holes 311, including allocating corresponding warehouse holes 311 to the hangers 100 according to the attributes 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 1031 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 512 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 512 allocates the corresponding warehouse holes 311 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 312 of the allocated warehouse hole 311 are stored in the warehouse information table. Subsequently, upon receiving a storage instruction, a storage-out instruction or a transfer instruction, the storage location management unit 512 sends the storage location code 312 corresponding to the designated hanger 100 to the corresponding storage location positioning unit.

[0108] In this embodiment, for the convenience of explanation, it is assumed that the storage location management unit 512 allocates a target storage location hole 311b on the first storage storage belt 31b to the hanger 100 when entering the warehouse, and the hanger 100 has been hung in the target storage location hole 311b, that is, Fig.11 For the location hole 311 at the position shown by B5, the location code corresponding to the target location hole 311b is recorded as the target location code 312b.

[0109] The storage control unit 505 controls the process of goods storage, and controls the storage device 20 to hang the hanger 100 into the storage hole 311 located at a predetermined position.

[0110] The first warehouse positioning control unit 506 is used to position and control the first warehouse storage belt 31b of the first warehouse belt storage device 33, and includes a target warehouse code acquisition unit 5061, a warehouse reference acquisition unit 5062, a warehouse interval acquisition unit 5063, a warehouse movement acquisition unit 5064, a target warehouse determination unit 5065 and a warehouse drive unit 5066.

[0111] The target location code acquisition unit 5061 obtains the corresponding target location code 312b from the location information table of the location information storage unit 503 according to the carrier identification code in the reservation information. The target location hole 311b corresponding to the target location code 312b is where the clothes hanger 100 reserved for removal is hung.

[0112] The storage reference acquisition unit 5062 acquires the storage location code 312 of the storage location hole 311 at the predetermined storage location reference position when the system is started, that is, the storage location hole 311 is used as the reference. Fig.11 At the position shown by B6, for the convenience of description, the storage location hole at this position is recorded as the storage reference storage location hole 311d, and the corresponding storage location code is recorded as the storage reference storage location code 312d.

[0113] The storage reference acquisition unit 5062 includes a two-dimensional code reading module 50621 and a two-dimensional code decoding module 50622. In this embodiment, the two-dimensional code reading module 50621 is set Fig.11 The camera at the position indicated by B6 in the figure can take a picture of the QR code at that position, thereby obtaining an image containing the QR code, and then the QR code decoding module 50622 processes and decodes the image to obtain the storage location code information contained in the QR code. The storage reference acquisition unit 5062 reads the storage location code information when the reservation-type belt storage system 10 is started, that is, before the first storage storage belt 31b starts to move. Fig.11 The two-dimensional code at position B6 in the middle is used as the warehouse reference location code 312d.

[0114] The storage interval acquisition unit 5063 acquires the target storage interval d1 between the storage retrieval position and the target storage hole 311b according to the storage reference storage hole code 312d and the target storage hole code 312b, that is, the number of storage holes 311 between the two.

[0115] Specifically, the storage interval acquisition unit 5063 queries the storage location information table according to the storage reference location code 312d to obtain the corresponding location serial number, which is recorded as the storage reference location i. Similarly, the target location x is obtained according to the target location code 311b. At the same time, the location information storage unit 502 also stores the reference retrieval interval D between the storage reference position and the scheduled retrieval position. The location serial number of the location hole 311 located at the scheduled retrieval position is recorded as the scheduled retrieval location a1, and the total number of location holes on the storage belt 31 is recorded as the total number S. Then, the above-mentioned target location interval d1 can be obtained according to the following formula:

[0116] Reserved retrieval position a1 = storage base position i + base retrieval interval D;

[0117] Target position interval d1 = scheduled withdrawal position a1 – target position x.

[0118] In the formula, the target storage position interval d1 can be a positive number or a negative number. When it is a positive number, the first storage belt 31b moves toward the predetermined conveying direction, and when it is a negative number, the first storage belt 31b moves in the opposite direction.

[0119] In this embodiment, it is assumed that the reference retrieval interval D=60. At the same time, serial number 0 in Table 2 is used as the storage reference location hole 311d, that is, the storage reference location i=0, and serial number 20 is used as the target location hole 311b, that is, the target location x=20. Therefore, the target location interval b1=20-0+60=80, that is, in order to make the target location hole 311b reach the predetermined storage retrieval position, the first storage storage belt 31b needs to move a distance of 80 location holes 311 in the predetermined conveying direction.

[0120] In addition, in the actual control procedure, in order to achieve a more accurate control effect, the target position interval d1 is actually calculated according to the following formula:

[0121] Reserved withdrawal position a1' = (storage base position i + base withdrawal interval D + total number S) mod total number S;

[0122] Target position interval d1 = scheduled withdrawal position a1' - target position x.

[0123] That is, the calculated reserved withdrawal position a1 is added to the total number S, and then divided by the total number S, and the remainder is taken as the actual reserved withdrawal position a1', so as to avoid some boundary conditions.

[0124] In addition, since there are many bin holes 311 on the storage belt 31, it takes a long time to rotate one circle. Therefore, in order to save the conveying time, in the actual control program, the target bin interval d1 is further processed and calculated:

[0125] When the target position interval d1>0:

[0126] It is further determined whether d1>S / 2. If it is not, the target bin interval d1 remains unchanged; if it is yes, that is, along the predetermined conveying direction (forward direction), the target bin hole 311b is far away from the predetermined storage and retrieval position, and the reverse direction can reach it faster. Therefore:

[0127] Target bin interval d1′=target bin interval d1−total number S.

[0128] Similarly, when the target position interval d1<0:

[0129] It is further determined whether d1<-S / 2. If it is not, the target bin interval d1 remains unchanged. If it is yes, that is, in the opposite direction of the predetermined conveying direction (reverse direction), the target bin hole 311b is far away from the storage and retrieval position, and the forward rotation can reach it faster. Therefore:

[0130] Target bin interval d1′=target bin interval d1+total number S.

[0131] Through the above-mentioned further processing and calculation, the target storage hole 311b can reach the storage retrieval position more quickly, and some boundary conditions that may cause program errors can be avoided.

[0132] The storage movement acquisition unit 5064 is used to sense and count the storage holes 311 passing through the predetermined storage detection position, so as to obtain the target moving position number k1 of the target storage hole 311b, that is, the distance of the target storage hole 311b having moved by the number of storage holes 311. The storage movement acquisition unit 5064 includes a storage hole sensing module 50641 and a storage hole counting module 50642.

[0133] The bin hole sensing module 50641 is an infrared sensor, which is arranged at a predetermined storage detection position beside the first storage belt 31, and is used to sense the bin hole 311 passing through the position. The infrared sensor generates different levels when sensing the steel belt part and the bin hole 311, that is, once a bin hole 311 passes through the storage detection position, the bin hole sensing module 50641 undergoes a level jump and generates a corresponding electrical signal.

[0134] The bin hole counting module 50642 counts once when receiving the electrical signal generated by the bin hole sensing module 50641, thereby obtaining the above-mentioned target number of moving bins k1. When the system is started and the first storage belt 311b starts to move, the bin hole counting module 50642 starts to count; and after the first storage belt 311b moves a predetermined number of bin intervals, when the storage reference bin hole 311d reaches the storage reference position again, that is, after the first storage belt 311b rotates a full circle, the bin hole counting module 50642 resets the count.

[0135] The target location determination unit 5065 determines whether the target location hole 311b has reached the predetermined storage retrieval position based on the target location interval obtained by the storage interval acquisition unit 5063 and the target number of mobile locations obtained by the storage movement acquisition unit 5064, that is, determines whether the target location interval d1 = target number of mobile locations k1.

[0136] In the actual control program, in order to facilitate the program implementation, the storage base position i is actually updated in real time according to the target mobile position k1, that is:

[0137] Storage base location i'=storage base location i+target number of moving locations k1.

[0138] Then, the target location interval d1 is updated in real time according to the updated storage reference location i', and the target location determination unit 5065 actually detects whether the target location interval d1 is 0. If it is detected to be 0, it is determined that the target location hole 311b has reached the storage retrieval position.

[0139] When the judgment is no, the target location determination unit 5065 further obtains the number of locations between the target location hole 311b and the storage and retrieval position, that is, the number of locations that the target location hole 311b needs to move further, and records it as the target current interval, that is:

[0140] Target current interval b1 = target position interval d1 – target number of moving positions k1.

[0141] In the actual control program, since the storage reference position i' and the target position interval d1 are updated in real time according to the target number of moving positions k1, the target current interval b1 is the real-time target position interval d1.

[0142] The storage driving unit 5066 controls the first storage driving mechanism 332 according to the determination result of the target storage position determination unit 5065, so that the first storage driving mechanism 332 drives the first storage storage belt 31b to move or stop, specifically including:

[0143] When the target storage position determination unit 5065 determines that the target position has not been reached and the target current interval b1 ≥ 20 storage holes 311, the storage drive unit 5066 drives the first storage storage belt 31b to move at a predetermined high speed. In this embodiment, the predetermined high speed is 18m / min-28m / min.

[0144] When the target storage position determination unit 5065 determines that the target storage position has not been reached, and 5 storage positions 311 ≤ the target current interval b1 < 20 storage positions 311, the storage drive unit 5066 drives the first storage storage belt 31b to move at a predetermined medium speed. In this embodiment, the predetermined medium speed is 12 m / min.

[0145] When the target storage position determination unit 5065 determines that the target position has not been reached and the target current interval b1 is less than 5 storage holes 311, the storage drive unit 5066 drives the first storage storage belt 31b to move at a predetermined low speed. In this embodiment, the predetermined low speed is 6 m / min.

[0146] When the target warehouse position determination unit 5065 determines that the reserved retrieval position has been reached, the storage drive unit 5066 controls the first storage drive mechanism 332 to stop working, so that the first storage storage belt 31b is stationary. At this time, the transfer device 35 can take the hanger 100 out of the warehouse position hole 311 located at the storage retrieval position.

[0147] The second storage positioning control unit 507 is used to position and control the second storage belt 31c of the second storage belt storage device 34. Its structure and function are consistent with those of the first storage positioning control unit 506, so they are not described again.

[0148] The reservation positioning control unit 508 is used to position and control the reservation storage belt 31a of the reservation belt storage device 32, and includes a reservation location code acquisition unit 5081, a reservation reference acquisition unit 5082, a reservation interval acquisition unit 5083, a reservation movement acquisition unit 5084, a reservation location determination unit 5085 and a reservation drive unit 5086.

[0149] The reserved position code acquisition unit 5081 selects one of the plurality of vacant position holes 311 on the reserved storage belt 31a as a reserved position hole 311a according to the predetermined reservation storage rule, and acquires the corresponding position code 312, recorded as the reserved position code 312a. The reserved position hole 311a is used to hang the hanger 100. For the convenience of description, in this embodiment, it is assumed that the reserved position hole 311a is located at Figure 7 At the position shown in B2.

[0150] In this embodiment, according to the thickness of the clothing, the reservation storage rule is set to store a hanger 100 every other slot 311 on the reservation storage belt 31a. That is, the reservation slot code acquisition unit 5081 first needs to find all the vacant slots 311, and then determine one by one whether the two slots 311 on both sides of the slot 311 are also vacant. If it is determined to be yes, the slot 311 is used as the reserved slot 311a, and if it is determined to be no, the next vacant slot 311 is determined.

[0151] The reservation reference acquisition unit 5082 acquires the position code 312 of the position hole 311 at the predetermined reservation reference position as the reservation reference position code 312c when the system is started. The reservation reference acquisition unit 5082 includes a camera set at the reservation reference position, that is, Figure 7 The function of the reference acquisition unit 5082 is the same as that of the storage reference acquisition unit 5062, and will not be described again.

[0152] The reservation interval acquisition unit 5083 acquires the reserved storage interval d2 between the reservation hanging position and the reserved storage hole 311a according to the reservation reference storage code 312c and the reserved storage code 312a. Its function and specific implementation method are basically the same as those of the storage interval acquisition unit 5063, and will not be repeated.

[0153] The reservation movement acquisition unit 5084 senses and counts the storage slots 311 passing through the predetermined reservation detection position, thereby acquiring the predetermined movement slot number k2 of the predetermined storage slot 311a. Its structure and function are consistent with those of the storage movement acquisition unit 5064 and will not be repeated.

[0154] The reserved storage position determination unit 5085 determines whether the reserved storage position hole 311a has reached the scheduled reservation hanging position based on the reserved storage position interval d2 obtained by the reservation interval acquisition unit 5083 and the scheduled movement storage position number k2 obtained by the reservation movement acquisition unit 5084, that is, determines whether the reserved storage position interval d2 = the scheduled movement storage position number k2.

[0155] The reservation drive unit 5086 controls the reservation drive mechanism 322 according to the determination result of the reserved storage position determination unit 5085, so that the reservation drive mechanism 322 drives the reservation storage belt 31a to move or stop. Its function and specific configuration are consistent with those of the storage drive unit 5066, and will not be described again.

[0156] The transfer control unit 509 controls the operation of the transfer device 35. Specifically, the transfer control unit 509 controls the transfer device 35 to move to the predetermined storage retrieval position and take out the hanger 100 from the target storage hole 311b; then, the transfer device 35 is controlled to move the hanger 100 to the predetermined reserved hanging position and hang the hanger 100 into the predetermined storage hole 311a.

[0157] The reservation control unit 510 controls the transfer of the hanger 100 according to the reservation retrieval time in the reservation information. Specifically, the reservation control unit 510 traverses the reservation information table, finds all hangers 100 whose time intervals between the reservation retrieval time and the current time are less than the predetermined interval threshold, and obtains the carrier identification codes of these hangers 100; then, for each of these hangers 100, the reservation control unit 510 controls the first storage positioning control unit 506 to locate and move the target storage hole 311b where the hanger 100 is hung to the storage retrieval position, and controls the reservation positioning control unit 508 to locate and move the reserved storage hole 311a to the reserved hanging position, and then controls the transfer control unit 509 to take the hanger 100 out of the target storage hole 311b, transfer it and hang it in the reserved storage hole 311a.

[0158] In this embodiment, the predetermined interval threshold is set to 7 days, that is, the reserved clothing to be taken is transferred to the reservation belt storage device 32 at most one week in advance. Assuming that the current time is October 1, according to the reservation information in Table 3, the hangers 100 with carrier identification codes ZJ0001, ZJ0004, and ZJ0012 should be transferred to the reservation belt storage device 32.

[0159] The outgoing control unit 511 controls the operation of the outgoing equipment 40 to thereby outgoing the hanger 100 .

[0160] In addition, in this embodiment, the cargo information storage unit 502, the warehouse information storage unit 503 and the reservation information storage unit 504 are set in the management end device (such as a local server or a cloud server), and the warehousing control unit 505, the transfer control unit 509, the outbound control unit 511, etc. are set in the control end device (such as an industrial computer).

[0161] Fig.17 It is a workflow diagram for positioning the target bin hole in an embodiment of the present invention.

[0162] like Fig.17 As shown, based on the above-mentioned appointment-based belt storage system 10, in this embodiment, the workflow for positioning the target storage hole 311b includes the following steps:

[0163] Step S1-1, the target location code acquisition unit 5061 acquires the target location code 312b of the target location hole 311b, and then proceeds to step S1-2;

[0164] Step S1-2, the storage interval obtaining unit 5063 obtains the target storage interval d1 between the target storage hole 311b and the storage reference storage hole 311d, and then proceeds to step S1-3;

[0165] Step S1-3, the storage movement acquisition unit 5064 acquires the target movement position k1 of the target position hole 311b, and then proceeds to step S1-4;

[0166] Step S1-4, the target position determination unit 5065 determines whether the target moving position d1 is equal to the target position interval k1, that is, whether the target position hole 311b reaches the predetermined storage and retrieval position. If it is determined to be negative, the process proceeds to step S1-4a, and if it is determined to be positive, the process proceeds to step S1-5;

[0167] Step S1-4a, waiting for a predetermined time, and then returning to step S1-4;

[0168] Step S1-5, the storage drive unit 5066 controls the first storage drive mechanism 332 to stop working, the first storage storage belt 31b is stationary, and then enters the end state.

[0169] Prior to the above steps, when the reservation-type belt storage system 10 is started, the storage reference acquisition unit 5062 has already acquired the storage reference location code 312d. After the system is started, the first storage storage belt 31b moves at a predetermined conveying speed.

[0170] Fig.18 It is a workflow diagram for positioning a predetermined bin hole in an embodiment of the present invention.

[0171] like Fig.18As shown, based on the above-mentioned appointment-based belt storage system 10, in this embodiment, the workflow for positioning the predetermined storage hole 311a includes the following steps:

[0172] Step S2-1, the reserved position code acquisition unit 5081 queries the position information table, obtains the position codes 312 of all n vacant position slots 311, and then enters step S2-1a;

[0173] Step S2-1a, setting k=1, that is, specifying the first vacant bin slot 311, and then proceeding to step S2-2;

[0174] Step S2-2, the reserved position code acquisition unit 5081 queries the position information table and determines whether the position slots 311 on both sides of the k-th vacant position slot 311 are also vacant. If the determination is no, the process proceeds to step S2-2a, and if the determination is yes, the process proceeds to step S2-3;

[0175] Step S2-2a, judging whether k is equal to n, that is, whether it is the last vacant slot 311, if it is judged as no, entering step S2-2b, if it is judged as yes, entering the end state;

[0176] Step S2-2b, setting k=k+1, i.e. specifying the next vacant storage slot 311, and then returning to step S2-2;

[0177] Step S2-3, the reserved position code acquisition unit 5081 takes the position hole 311 as the reserved position hole 311a, and acquires the corresponding position code 312 as the reserved position code 312a, and then proceeds to step S2-4;

[0199] Specifically, the first storage positioning control unit 506 has a target location code acquisition unit 5061, so it can acquire the target location code 312b of the target location hole 311b where the hanger 100 is hung according to the carrier identification code of the hanger 100 to be taken out in the reservation information; because it has a storage reference acquisition unit 5062, it can acquire the location code at the predetermined reference position as the storage reference location code 312d when the system is started; because it has a storage interval acquisition unit 5063, it can acquire the target location interval between the target location hole 311b and the predetermined storage retrieval position; because it has a storage movement acquisition unit 5064, It is capable of sensing and counting the storage holes 311 passing through the predetermined detection position, thereby obtaining the target moving storage position number of the target storage hole 311b; since it has a target storage determination unit 5065, it is capable of determining whether the target storage hole 311b has reached the predetermined storage retrieval position based on the obtained target storage interval and the target moving storage position number; and since it has a storage drive unit 5066, it is capable of controlling the first storage drive mechanism 332 based on the determination result of the target storage determination unit 5065, driving the first storage storage belt 31b to move or stop, thereby accurately positioning the target storage hole 311b to the storage retrieval position.

[0200] Similarly, since the second storage positioning control unit 507 is provided, the storage hole 311 of the second storage storage device 34 in which the hanger 100 in the reservation information is hung can be accurately positioned at the predetermined take-out position.

[0201] Furthermore, the reservation positioning control unit 508 has a reservation position code acquisition unit 5081, which can query the position information table to obtain all the vacant position holes 311 on the reservation storage belt 31a, and then judge whether the vacant position holes 311 meet the requirements in turn according to the predetermined reservation storage rules, and use the first position hole 311 that meets the requirements as the reserved position hole 311a for receiving the transferred hanger 100. Furthermore, similarly, the reservation positioning control unit 508 can accurately locate the reserved position hole 311a to the predetermined reservation hanging position.

[0202] Furthermore, since there is a reservation control unit 510, the hangers 100 to be transferred can be determined according to the scheduled retrieval time in the reservation information, and the carrier identification codes of these hangers 100 can be obtained. Then, for each hanger 100 to be transferred, the reservation control unit 510 controls the first storage positioning control unit 506 and the second storage positioning control unit 507 to locate the target storage hole 311b, and controls the reservation positioning control unit 508 to determine and locate the predetermined storage hole 311a, and then controls the transfer device 35 to transfer the hanger 100. Therefore, the hanger 100 can be transferred from the storage belt storage device to the reservation belt storage device 32 in advance according to the scheduled retrieval time, so as to facilitate the staff or customers to take it.
