The outbound conveying motor 323 is connected to one of the outbound conveying sprockets 322, and the outbound conveying motor 323 drives the outbound conveying chain 321 to transmit, thereby realizing the movement of the cloth roll pallet 4 on the outbound bearing base 31.

[0078] The following is an explanation of the steps for warehousing steel pipe rolls.

[0079] After the production of steel pipe rolls is completed, an identification label will be affixed to the steel pipe rolls. The identification label is provided with a roll QR code. The roll QR code points to the basic information of the roll. The roll basics can be obtained by scanning the roll QR code. The roll basic information includes but is not limited to product number, product name, specification, production batch number, batch number description, production machine number and production record personnel, etc. The roll basic information can be modified according to production needs.

[0080] All electrical equipment of the above-mentioned warehousing unit 1, three-dimensional storage unit 2 and outgoing warehouse unit 3 are electrically connected to the host computer and controlled by the host computer, wherein the host computer is connected to a handheld terminal for communication.

[0081] The forklift transports the steel pipe cloth roll to the cloth roll pallet 4 on the pallet storage rack 11. The staff opens the warehouse operating system of the handheld terminal. The handheld terminal scans the cloth roll QR code on the steel pipe cloth roll in the warehouse operating system to obtain the basic information of the cloth roll, and the basic information of the cloth roll is uploaded to the host computer.

[0082] To execute the steel pipe roll storage operation, the staff clicks on the corresponding layer position of the pallet storage rack 11 where the steel pipe roll is placed in the warehouse operating system of the handheld terminal. At this time, the upper computer will traverse the storage locations 22 on the three-dimensional storage rack 21, and can query all storage locations 22 in the order from left to right and from top to bottom of the three-dimensional storage rack 21. The first empty storage location 22 is selected as the storage location to generate storage information, and the basic information of the roll and the storage information are associated to generate storage instructions.

[0083] Based on the warehousing instruction, the pallet lifter 12 transfers the cloth roll pallet 4 carrying the steel pipe cloth roll on the corresponding layer of the pallet storage rack 11 to the warehousing docking base 13, and the warehousing docking trolley 14 transfers the cloth roll pallet 4 (with the steel pipe cloth roll) in the warehousing docking base 13 to the warehousing carrying base 15. The storage stacker 24 moves the cloth roll pallet 4 (with the steel pipe cloth roll) in the warehousing carrying base 15 to the corresponding storage position 22 on the three-dimensional storage rack 21 to complete the warehousing action.

[0084] The following is an explanation of the steps for shipping steel pipe rolls.

[0085] In subsequent production steps, when steel pipe fabric rolls are needed for production, they need to be shipped out of the warehouse. At this point, the staff generates a material order in the host computer. The order contains the product number, product name, and specifications of the required reflective fabric, and matches it to the corresponding steel pipe fabric roll in the storage location 22 of the three-dimensional storage rack 21. The host computer then generates a shipment instruction based on the order.

[0086] The storage stacker 24 transfers the cloth roll pallet 4 in the storage location 22 on the three-dimensional storage rack 21 to the outbound carrying base 31 based on the outbound instruction.

[0087] After the steel pipe cloth rolls on the cloth roll pallet 4 are transferred, the cloth roll pallet 4 (without the steel pipe cloth rolls) needs to be transferred to the three-dimensional storage rack 21. At this time, the upper computer will traverse the storage locations 22 on the three-dimensional warehouse, select the first empty storage location 22 as the return location to generate a return instruction, and the storage stacker 24 will transfer the current cloth roll pallet 4 (without the steel pipe cloth rolls) to the storage location 22 based on the return instruction.

[0088] The steps for returning the cloth roll tray 4 to the warehouse are described below.

[0089] Since the steel pipe cloth rolls are placed on the cloth roll pallet 4 when entering and leaving the warehouse, when the steel pipe cloth rolls are put into the warehouse, there will be a lack of an empty cloth roll pallet 4 on the pallet storage rack 11. Therefore, an empty cloth roll pallet 4 needs to be transferred to the pallet storage rack 11 for replenishment to ensure that each layer of the pallet storage rack 11 has a cloth roll pallet 4 without steel pipe cloth rolls.

[0090] Therefore, when the upper computer does not perform the storage action and the outbound action on the storage stacker 24 and detects that there is a lack of empty cloth roll pallets 4 on the pallet storage rack 11, it will perform the return action.

[0091] In the return step, the upper computer will traverse all storage locations 22 on the three-dimensional storage rack 21 that serve as return locations. The return location is the storage location 22 where the cloth roll pallet 4 that does not have steel pipe cloth rolls is transferred back to the three-dimensional storage rack 21 is stored. The upper computer will sort all storage locations 22 marked as return locations, and select the cloth roll pallet 4 in the first storage location 22 for return. The storage stacker 24 will transfer the cloth roll pallet 4 (without steel pipe cloth rolls) in the selected storage location 22 to the storage load-bearing base 15, and transfer it to the pallet storage rack 11 via the storage docking trolley 14, the storage docking base 13, and the pallet elevator 12.

[0092] The reflective fabric in the steel pipe fabric roll in this application has a micro-bead surface and a base surface. The micro-bead surface is the reflective surface, wherein the micro-bead surface is the front side of the reflective fabric, and the base surface is the back side of the reflective fabric. After the reflective fabric is produced, the roll direction of the steel pipe fabric roll can be determined. However, during the process of the steel pipe fabric roll being transported by a forklift, until the steel pipe fabric roll is stored in the storage location 22, and until the steel pipe fabric roll is shipped out of the warehouse, the roll direction of the steel pipe fabric roll cannot be recorded.

[0093] In this embodiment, the steel pipe cloth roll is described by taking the micro-bead surface on the inner side as an example.

[0094] Reference Figure 14a and Figure 14b As shown, when the reflective fabric is subsequently slit, the slitter is designed to wind in a uniform clockwise direction. If the material order specifies that the reflective fabric to be slit has the microbead side facing outward, the steel pipe roll is rolled counterclockwise to accommodate the slitter's needs. However, if the material order specifies that the reflective fabric to be slit has the base side facing outward, the steel pipe roll will need to be rotated from a counterclockwise direction to a clockwise direction to accommodate the slitter's needs. Therefore, when the steel pipe roll is shipped out of the warehouse, the roll's direction must be adjusted to match the material order.

[0095] Reference Figure 15 As shown, each outbound carrying base 31 is provided with a pallet steering mechanism 5 .

[0096] The pallet steering mechanism 5 includes a steering base 51, a lifting hydraulic cylinder 52 and a steering base 53. The steering base 51 is arranged in the outbound load-bearing base 31, the lifting hydraulic cylinder 52 is arranged on the steering base 51, and the steering base 53 is slidably installed on the steering base 51 along the vertical direction. The output rod of the lifting hydraulic cylinder 52 is connected to the steering base 53, and the steering base 53 can move up and down under the action of the lifting hydraulic cylinder 52.

[0097] A steering platform 54 is rotatably mounted on the steering base 53, a steering gear 55 is mounted on the rotating shaft of the steering platform 54, a steering rack 56 meshing with the steering gear 55 is slidably mounted on the steering base 53, and a steering hydraulic cylinder 57 for driving the steering rack 56 to slide is provided on the steering base 53. The steering hydraulic cylinder 57 can drive the steering rack 56 to slide. Since the steering rack 56 is meshed with the steering gear 55, the steering platform 54 can rotate on the steering base 53.

[0098] The cloth roll pallet 4 is moved to the position of the pallet steering mechanism 5 under the transportation of the outbound carrying base 31. When the steel pipe cloth roll on the cloth roll pallet 4 needs to be turned, the jacking hydraulic cylinder 52 will drive the steering base 53 to move upward, so that the steering platform 54 is supported on the bottom of the cloth roll pallet 4, so that the cloth roll pallet 4 is separated from the outbound carrying base 31. At this time, the steering hydraulic cylinder 57 drives the steering rack 56 to control the steering platform 54 to complete a 180° turn.

[0099] Reference Figure 16 As shown, to achieve automated steering of the steel pipe rolls, the outbound carrying base 31 is provided with a roll direction detection mechanism 6 at the location of the pallet steering mechanism 5 for detecting the roll direction of the steel pipe rolls on the roll pallet 4. The roll direction detection mechanism 6 includes an identification camera 61 disposed above the pallet steering mechanism 5 and a rotary docking assembly 62 disposed on one side of the pallet steering mechanism 5.

[0100] An identification label is attached to the surface of the steel pipe roll. The label contains not only a QR code but also an identification pattern indicating the roll's roll direction. In one embodiment, the identification pattern can be an arrow. After the steel pipe roll is produced, the label is attached to the surface of the roll by a staff member, with the arrow indicating the roll's roll direction.

[0101] Both ends of the steel pipe cloth roll are suspended and supported on the cloth roll tray 4. Both ends of the steel pipe cloth roll are provided with docking holes 63. The docking holes 63 are provided along the axial direction of the steel pipe cloth roll and are hexagonal holes.

[0102] The rotary docking assembly 62 includes a support frame 621 and a docking seat 622 slidably mounted on the support frame 621. A rotary motor 623 is fixed to the docking seat 622. A docking shaft 624 is mounted on the output shaft of the rotary motor 623. The docking shaft 624 is adapted to fit within the docking hole 63. A docking cylinder 625 is provided on the support frame 621 for driving the docking seat 622 to move so as to insert the docking shaft 624 into the docking hole 63. In one embodiment, the docking shaft 624 includes a first shaft and a second shaft. The second shaft is coaxially fixed to the output shaft of the rotary motor 623. A mounting cavity is defined in the axial direction of the second shaft. The first shaft is slidably inserted into the mounting cavity. An elastic spring is disposed in the mounting cavity. The first shaft is hexagonal in shape, and its shape matches that of the docking hole 63.

[0103] The rotary docking assembly 62 controls the steel pipe cloth roll to rotate on the cloth roll tray 4, and the identification camera 61 is used to identify the identification label on the steel pipe cloth roll to determine the cloth roll of the steel pipe cloth roll according to the identification pattern to control the steering action of the tray steering mechanism 5 backward.

[0104] Specifically, after the production of the steel pipe cloth roll is completed, an identification label is affixed to the steel pipe cloth roll. The identification label contains not only a cloth roll QR code but also an identification pattern. The cloth roll QR code is configured with basic information of the cloth roll. The basic information of the cloth roll records the orientation of the microbead surface of the reflective fabric, that is, whether the microbead surface is on the inside or outside of the steel pipe cloth roll. The identification pattern records the rolling direction of the steel pipe cloth roll.

[0105] Reference Figure 17a and Figure 17b As shown, the rotary docking assembly 62 controls the steel pipe cloth roll to rotate clockwise on the cloth roll tray 4. During one rotation of the steel pipe cloth roll, the identification camera 61 can identify the identification pattern on the identification label. If the arrow direction of the identification pattern is left, it means that the steel pipe cloth roll is rolled clockwise. If the arrow direction of the identification pattern is right, it means that the steel pipe cloth roll is rolled counterclockwise.

[0106] When the steel pipe cloth roll is shipped out of the warehouse, the upper computer will retrieve the orientation of the micro-bead surface of the reflective fabric of the steel pipe cloth roll. This implementation is explained by taking the micro-bead surface of the steel pipe cloth roll on the inside, and the reflective fabric after cutting with the micro-bead surface inside and the base surface outside as an example.

[0107] 1. The micro-bead surface of the steel pipe cloth roll is inside and the base surface is outside. It is identified that the roll direction is counterclockwise. The slitting requirement is that the micro-bead surface is inside and the base surface is outside. Therefore, the direction of the steel pipe cloth roll is controlled.

[0108] 2. The micro-bead surface of the steel pipe cloth roll is inside and the base surface is outside. It is identified that the rolling direction is counterclockwise. The slitting requirement is that the micro-bead surface is outside and the base surface is inside. Therefore, the steel pipe cloth roll is controlled not to turn.

[0109] 3. The micro-bead surface of the steel pipe cloth roll is inside and the base surface is outside. It is identified that the rolling direction is clockwise. The slitting requirement is that the micro-bead surface is inside and the base surface is outside. Therefore, the steel pipe cloth roll is controlled not to turn.

[0110] 4. The micro-bead surface of the steel pipe cloth roll is inside and the base surface is outside. It is identified that the roll direction is clockwise. The slitting requirement is that the micro-bead surface is outside and the base surface is inside. Therefore, the direction of the steel pipe cloth roll is controlled.

[0111] The above four situations are explained with examples, and other situations are not listed one by one.

[0112] Therefore, the pallet steering mechanism 5 and the roll direction detection mechanism 6 can effectively make the steel pipe rolls adapt to the subsequent slitting process when leaving the warehouse, thereby improving the degree of automation of the entire equipment.

[0117] Step A100: Transfer the steel pipe fabric roll to the fabric roll tray 4 on the tray storage rack 11, wherein an identification label is attached to the steel pipe fabric roll, and the identification label is provided with a fabric roll QR code;

[0118] Step A200: Scan the QR code on the steel pipe fabric roll to obtain basic fabric roll information indicated by the QR code, traverse the storage locations 22 on the three-dimensional storage rack 21, select an empty storage location 22 as the storage location to generate storage information, and associate the basic fabric roll information with the storage information to generate a storage instruction;

[0119] In step A300, the pallet elevator 12 transfers the cloth roll pallet 4 carrying the steel pipe cloth roll on the corresponding layer of the pallet storage rack 11 to the storage docking base 13 based on the storage instruction.

The storage stacker 24 moves the cloth roll pallet 4 in the storage carrying base 15 to the corresponding storage location 22 on the three-dimensional storage rack 21.

[0120] The steps of outbound delivery include:

[0121] Step B100: Based on the outbound instruction, the storage stacker 24 transfers the cloth roll pallet 4 in the storage location 22 on the three-dimensional storage rack 21 to the outbound carrying base 31;

[0122] Step B200, after the steel pipe cloth roll on the cloth roll pallet 4 is transferred, traverse the storage locations 22 on the three-dimensional storage rack 21, select an empty storage location 22 as the return location to generate a return instruction, and the storage stacker 24 transfers the current cloth roll pallet 4 to the storage location 22 based on the return instruction.

[0123] When the storage stacker 24 does not execute the storage step and the storage step, the storage return step is executed. The storage return step includes:

[0124] Step C100, traversing all storage locations 22 on the three-dimensional storage rack 21 that are used as return storage locations;

[0125] In step C200 , the storage stacker 24 transfers the cloth roll pallet 4 in the selected storage location 22 to the storage carrying base 15 , and transfers it to the pallet storage rack 11 via the storage docking trolley 14 , the storage docking base 13 , and the pallet elevator 12 .

[0126] Therefore, the present application transfers the cloth roll pallet 4 carrying the steel pipe cloth roll to the storage docking base 13, and then transfers it to the storage carrying base 15 through the storage docking trolley 14. The storage stacker 24 can transfer the cloth roll pallet 4 loaded with the steel pipe cloth roll to the storage location 22 of the three-dimensional storage rack 21 for storage. The storage stacker 24 also transfers the cloth roll pallet 4 in the storage location 22 in the three-dimensional storage rack 21 for outbound delivery. The entire process is uniformly carried out through the storage stacker 24 for storage and outbound delivery of the steel pipe cloth rolls, with a high degree of automation, thereby effectively improving the efficiency of storage and outbound delivery of the steel pipe cloth rolls.

[0127] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
