Description

Technical Field

[0001] This invention relates to a conveying device, and more particularly to a strip material sorting system and sorting method. Background Technology

[0002] When storing materials, if the material volume is small, multiple materials are usually arranged in the front-to-back direction on each storage layer. For example, strip-shaped materials are also called strips. Currently, strips are generally stored in each storage layer from the inside out. However, when strips need to be taken out, they must be taken out starting from the outermost strip. They cannot be taken out directly from the innermost strip, which is not very flexible. Therefore, there is an urgent need for a system that can easily sort and retrieve strips in different positions. Summary of the Invention

[0003] The purpose of this invention is to provide a strip material sorting system and sorting method to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this invention is:

[0005] A strip material sorting system includes: a storage rack having a storage layer, wherein a plurality of first gaps are spaced apart along the left-right direction on the storage layer, and the plurality of first gaps extend downward to the rear side of the storage layer; a first conveyor line having a conveying surface extending along the left-right direction, wherein a plurality of second gaps are spaced apart along the left-right direction on the conveying surface, and the plurality of second gaps are respectively directly opposite the plurality of first gaps; and a sorting mechanism having a transfer frame and a tray that can move back and forth between the conveying surface and any of the storage layers, wherein the transfer frame has a transfer tray that can move up and down. The transfer trays are arranged in multiple directions along the left and right, and the multiple transfer trays are respectively directly opposite to the multiple second gaps. The bracket is located above the transfer frame, and the bracket is connected with multiple support rods at intervals along the left and right directions. The multiple support rods are respectively staggered from the multiple transfer trays. The lifting mechanism includes a stop bar and a lifting frame located below the conveying surface. The stop bar can protrude upward or retract downward from one of the second gaps into the conveying surface. The lifting frame has lifting ends directly opposite the multiple second gaps. The multiple lifting ends can protrude upward or retract downward from the multiple second gaps into the conveying surface.

[0006] This technical solution has at least the following beneficial effects: When the material to be stored is placed on the first conveyor line, the first conveyor line moves the material to the sorting mechanism. At this time, a baffle protrudes upward from a second gap onto the conveyor surface, blocking the material from continuing to move. Then, multiple lifting ends protrude upward from multiple second gaps onto the conveyor surface, causing the material to be lifted away from the conveyor surface. Next, the bracket approaches the conveyor surface, and multiple support rods on the bracket move below the material. The multiple lifting ends move downward, placing the material on multiple support rods. The multiple lifting ends continue to descend into the conveyor surface, while the bracket moves the material away from the first conveyor line, thus achieving material retrieval from the first conveyor line. When the material needs to be stored in the storage rack, the transfer frame and bracket move to the storage layer where the material needs to be placed. The transfer frame moves below the storage layer, and the bracket moves the material above the storage layer. At this time, multiple transfer trays pass through multiple first gaps in the storage layer, lifting the material on multiple brackets upward. The bracket moves multiple... The material is stored by placing the material on the storage layer after the support rods leave the storage layer. When the material needs to be removed from the storage layer, the transfer frame and support rods move to the storage layer where the material is located. The transfer frame moves below the storage layer, and multiple transfer trays on the transfer frame pass upward through multiple first gaps in the storage layer, lifting the material upward. Then the support rods move above the storage layer, causing multiple support rods on the support rods to move below the material. Next, multiple transfer trays move downward, placing the material on multiple support rods. The multiple transfer trays continue to move downward to the bottom of the storage layer, while the support rods move the material away from the storage layer, allowing the material to be removed from the storage layer. After the material is fed into the first conveyor line, it can be removed and placed at different positions on different storage layers. When the material needs to be removed, it can be directly removed from any position, greatly improving the flexibility and convenience of material sorting and storage, and making it more practical.

[0007] As a further improvement to the above technical solution, the sorting mechanism includes a column, a first lifting drive, a slide, a lower connecting frame, and a first translation drive. The column is located behind the storage rack. The first lifting drive is connected to the column, and the slide is connected to the first lifting drive. The first lifting drive can drive the slide to move up and down. The lower connecting frame is connected to the slide, and the first translation drive is connected to the slide. The transfer frame is connected to the first translation drive, and the first translation drive can drive the transfer frame to move back and forth. The first lifting drive and the first translation drive can provide driving forces for the transfer frame to move in the up-down and back-forward directions, respectively, so that the transfer frame can move to storage layers of different heights and to positions in the back-forward direction on each storage layer, realizing the storage and retrieval of materials.

[0008] As a further improvement to the above technical solution, the sorting mechanism further includes a scissor mechanism, a connecting rod, and a second translation drive. The second translation drive is connected to the lower connecting frame, and the connecting rod is connected to the second translation drive. The second translation drive can drive the connecting rod to move back and forth. One bottom end of the scissor mechanism is rotatably connected to the lower connecting frame, and the other bottom end of the scissor mechanism is rotatably connected to the connecting rod. Multiple scissor mechanisms are arranged in the left-right direction. One top end of each of the multiple scissor mechanisms is rotatably connected to the intermediate transfer plate, and the other top end of each of the multiple scissor mechanisms is rotatably connected to a sliding shaft. The multiple sliding shafts are slidably connected to the multiple intermediate transfer plates in the front-back direction. When multiple transfer pallets need to be lifted upwards, the second translation drive moves the connecting rod closer to the position where the scissor mechanism is connected to the lower connecting frame. At this time, the sliding shaft on the top side of the scissor mechanism also moves in the same direction on the transfer pallets. The entire scissor mechanism narrows in the front-back direction and lifts the transfer pallets upwards. In this way, the connecting rod lifts multiple transfer pallets upwards simultaneously through multiple scissor mechanisms. When multiple transfer pallets need to be lowered, the second translation drive moves the connecting rod away from the position where the scissor mechanism is connected to the lower connecting frame. Similarly, the sliding shaft on the top side of the scissor mechanism moves in the same direction on the transfer pallets. The entire scissor mechanism unfolds in the front-back direction, causing the transfer pallets to lower. In this way, the connecting rod drives multiple transfer pallets to lower through multiple scissor mechanisms.

[0009] As a further improvement to the above technical solution, the sorting mechanism further includes an upper connecting frame and a third translation drive. The upper connecting frame is connected to the slide block above the lower connecting frame. The third translation drive is connected to the upper connecting frame, and the bracket is connected to the third translation drive. The third translation drive can drive the upper connecting frame to move back and forth. The upper connecting frame is also connected to the slide block and moves up and down synchronously with the lower connecting frame. When the bracket is needed, the third translation drive provides a driving force to the upper connecting frame in the back-and-forth direction, allowing multiple brackets to move to different back and forth positions to store and retrieve materials.

[0010] As a further improvement to the above technical solution, the front and rear sides of the transfer pallet are bent upwards respectively. After the transfer pallet lifts the material upwards, the upward bending of its front and rear sides can restrict the material's movement in the front-to-back direction, making it less likely for the material to fall off the transfer pallet.

[0011] As a further improvement to the above technical solution, multiple lifting mechanisms are spaced apart along the left-right direction, and sorting mechanisms are respectively arranged behind each of the multiple lifting mechanisms. Multiple storage layers can be divided along the left-right direction to form multiple different storage zones. In this case, one lifting mechanism and one sorting mechanism correspond to one storage zone. Thus, after the first conveyor line transfers the material to the corresponding storage zone, the corresponding lifting mechanism and sorting mechanism transfer the material to the storage layer within that storage zone where it needs to be placed. This enables faster and more efficient zoned management of materials, making it more practical.

[0012] As a further improvement to the above technical solution, the present invention also includes a second conveyor line located below the first conveyor line. The second conveyor line has third gaps respectively positioned opposite to the plurality of second gaps, and the conveying direction of the second conveyor line is opposite to that of the first conveyor line. The first conveyor line is used for loading and storing the sheet metal. When it is necessary to remove the sheet metal, the sheet metal removed from the storage area can be transferred to the second conveyor line, which will then convey the sheet metal outwards. This achieves separate conveying for storing and retrieving the sheet metal.

[0013] A sorting method using the above-described strip sorting system includes the following steps: the baffle protrudes upward from a second gap onto the conveying surface and blocks the material on the conveying surface; a plurality of lifting ends protrude upward from a plurality of second gaps onto the conveying surface and lift the material away from the conveying surface; the bracket moves above the conveying surface; the plurality of support rods move below the material; the plurality of lifting ends retract downward below the conveying surface; and the bracket drives the material away from the first conveying line.

[0014] This technical solution has at least the following beneficial effects: Through this sorting method, the first conveyor line can first transfer the boards to the corresponding storage positions on the storage rack, and then the lifting mechanism and the sorting mechanism can take out the boards for storage. Multiple boards can be operated at the same time, which greatly improves the sorting efficiency of the boards and thus improves production efficiency.

[0015] A sorting method using the above-described strip sorting system includes the following steps: in the same storage layer, the transfer frame moves to below the storage layer, the tray moves to above the storage layer, a plurality of transfer trays pass through a plurality of first gaps and lift the materials on the plurality of trays upwards, the trays move away from the storage layer, and the transfer frame moves downwards and places the materials on the storage layer.

[0016] This technical solution has at least the following beneficial effects: through this sorting method, materials can be moved to the storage layer where they need to be placed, and then placed in different positions of the storage layer in the front-back direction, thereby improving the flexibility of material placement.

[0017] A sorting method using the above-described strip sorting system includes the following steps: in the same storage layer, the transfer frame moves to below the storage layer, multiple transfer trays pass upward through multiple first gaps and lift the material on the storage layer upward, the tray moves to above the storage layer, multiple support rods move to below the material, multiple transfer trays move downward and place the material on the multiple support rods, and the tray moves the material away from the storage frame.

[0018] This technical solution has at least the following beneficial effects: through this sorting method, the material can be moved to the storage layer where the material to be taken out needs to be taken out, and then the material arranged in the front-back direction on the storage layer can be taken out as needed, which greatly improves the flexibility of material removal.

Detailed Implementation

[0028] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention. Furthermore, all connection relationships mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0029] Reference Figure 1 , Figure 2 and Figure 3A strip material sorting system includes: a storage rack 1, which has a storage layer 11, wherein a plurality of first gaps are spaced apart along the left-right direction on the storage layer 11, and the plurality of first gaps extend downward to the rear side of the storage layer 11; a first conveyor line 21, which has a conveying surface extending along the left-right direction, wherein a plurality of second gaps are spaced apart along the left-right direction on the conveying surface, and the plurality of second gaps are respectively directly opposite the plurality of first gaps; and a sorting mechanism 4, which has a transfer frame 426 and a bracket 431 that can move back and forth between the conveying surface and any one of the storage layers 11, wherein the transfer frame 426 has a transfer tray 428 that can move up and down. Multiple transfer trays 428 are arranged along the left-right direction, and the multiple transfer trays 428 are respectively directly opposite to the multiple second gaps. The bracket 431 is located above the transfer frame 426. Multiple support rods 432 are connected to the bracket 431 at intervals along the left-right direction. The multiple support rods 432 are respectively staggered from the multiple transfer trays 428. The lifting mechanism includes a stop rod 31 located below the conveying surface and a lifting frame. The stop rod 31 can protrude upward or retract downward from one of the second gaps into the conveying surface. The lifting frame has lifting ends directly opposite the multiple second gaps. The multiple lifting ends can respectively protrude upward or retract downward from the multiple second gaps into the conveying surface.

[0030] In this strip sorting system, the materials to be stored are placed on the first conveyor line 21, which then moves the materials to the sorting mechanism 4. At this time, the baffle 31 protrudes upward from one of the second gaps onto the conveying surface, blocking the material from continuing to move. Then, multiple lifting ends protrude upward from multiple of the second gaps onto the conveying surface, causing the material to be lifted away from the conveying surface. Next, the bracket 431 approaches the conveying surface, and multiple support rods 432 on the bracket 431 move to below the material. The multiple lifting ends move downward, placing the material on the multiple support rods 432. The material continues to be fed downwards into the conveying surface, while the bracket 431 moves the material away from the first conveyor line 21, thus retrieving material from the first conveyor line 21. When the material needs to be stored in the storage rack 1, the transfer frame 426 and the bracket 431 move to the storage layer 11 where the material needs to be placed. The transfer frame 426 moves below the storage layer 11, and the bracket 431 moves the material above the storage layer 11. At this time, multiple transfer trays 428 pass through multiple first gaps in the storage layer 11, lifting the material on the multiple brackets 431 upwards. The brackets 431 then move multiple support rods 432 away from the storage layer 11. The material is placed on the storage layer 11 by the transfer frame 426, which moves downwards to store the material. When the material needs to be removed from the storage rack 1, the transfer frame 426 and the bracket 431 move to the storage layer 11 where the material is located. The transfer frame 426 moves below the storage layer 11, and the multiple transfer trays 428 on the transfer frame 426 pass upwards through the multiple first gaps in the storage layer 11, lifting the material on the storage layer 11 upwards. Then the bracket 431 moves above the storage layer 11, so that the multiple support rods 432 on the bracket 431... The material is moved below the material, and then multiple transfer trays 428 move downwards, placing the material on multiple support rods 432. The multiple transfer trays 428 continue to move downwards to below the storage layer 11, while the support 431 moves the material away from the storage rack 1, thus removing the material from the storage rack 1. After the material is sent into the first conveyor line 21, it can be taken out and placed in different front and back positions on different storage layers 11. When it is necessary to take out the material, it can be taken out directly from any position, which greatly improves the flexibility and convenience of material sorting and storage, and makes it more practical.

[0031] The sorting mechanism 4 has a drive structure that can drive the transfer frame 426 to move in the up-down and back-and-forth directions. Specifically, the sorting mechanism 4 includes a column 411, a first lifting drive 412, a slide 413, a lower connecting frame 421, and a first translation drive 422. The column 411 is located behind the storage rack 1. The first lifting drive 412 is connected to the column 411. The slide 413 is connected to the first lifting drive 412. The first lifting drive 412 can drive the slide 413 to move up and down. The lower connecting frame 421 is connected to the slide 413. The first translation drive 422 is connected to the slide 413. The transfer frame 426 is connected to the first translation drive 422. The first translation drive 422 can drive the transfer frame 426 to move back and forth. The first lifting drive 412 and the first translation drive 422 can respectively provide driving force to the transfer frame 426 in the up-down and back-forward directions, so that the transfer frame 426 can be moved to storage layers 11 at different heights and to the position in the back-forward direction on each storage layer 11, so as to realize the storage and retrieval of materials.

[0032] For the vertical movement of the transfer pallets 428, a lifting drive source can be directly installed on the transfer frame 426 to drive its movement. For example, a cylinder can be installed on the transfer frame 426, and the cylinder is connected to a transmission rod. Multiple transfer pallets 428 are connected to the transmission rod. In this case, the cylinder can drive the multiple transfer pallets 428 to move up and down through the transmission rod. In order to improve the stability of the multiple transfer pallets 428 during movement, in this embodiment, the sorting mechanism 4 also includes a scissor mechanism 423, a connecting rod 425, and a second translation drive 427. The second translation drive 427 is connected to the lower connecting frame 421, and the connecting rod 425 is connected to the second translation drive 427. The second translation drive 427 can drive the connecting rod 425 to move back and forth. One end of the bottom side of the scissor mechanism 423 is rotatably connected to the lower connecting frame 421, and the other end of the bottom side of the scissor mechanism 423 is rotatably connected to... On the connecting rod 425, multiple scissor mechanisms 423 are arranged in the left-right direction. One top end of each scissor mechanism 423 is rotatably connected to the transfer plate 428, and the other top end of each scissor mechanism 423 is rotatably connected to a sliding shaft 424. The sliding shafts 424 are slidably connected to the transfer plates 428 in the front-back direction. In practical applications, the scissor mechanism 423 is formed by multiple intersecting two-links 425 that are rotatably connected to each other. At this time, the two bottom ends of the bottom two-links 425 are the two bottom ends of the scissor mechanism 423, and the two top ends of the top two-links 425 are the two top ends of the scissor mechanism 423. A sliding frame can be slidably connected to the transfer frame 426 in the front-back direction, and the connecting rod 425 is rotatably connected to the sliding frame. The second translation drive 427 drives the sliding frame, thereby improving the stability of the sliding of the connecting rod 425. When multiple transfer pallets 428 need to be lifted upwards, the second translation drive 427 drives the connecting rod 425 to rotate towards the position of the scissor mechanism 423 connected to the lower connecting frame 421. At this time, the sliding shaft 424 on the top side of the scissor mechanism 423 also moves in the same direction on the transfer pallets 428. The entire scissor mechanism 423 narrows in the front-back direction and lifts the transfer pallets 428 upwards. In this way, the connecting rod 425, through multiple scissor mechanisms 423, simultaneously lifts multiple transfer pallets 428 upwards. When the multiple transfer pallets 428 need to be lowered, the second translation drive 427 drives the connecting rod 425 to rotate towards the scissor mechanism 423 and move away from the position connected to the lower connecting frame 421. Similarly, the sliding shaft 424 on the top side of the scissor mechanism 423 also moves in the same direction on the transfer pallets 428. The entire scissor mechanism 423 unfolds in the front-back direction, causing the transfer pallets 428 to lower. In this way, the connecting rod 425 drives the multiple transfer pallets 428 to lower through the multiple scissor mechanisms 423.

[0033] The sorting mechanism 4 has a drive structure that can move the tray 431 in the up-down and back-forward directions. To reduce the number of drive sources, the tray 431 and the transfer frame 426 can share a single drive source in the up-down direction. Specifically, the sorting mechanism 4 also includes an upper connecting frame 433 and a third translation drive 434. The upper connecting frame 433 is connected to the slide 413 above the lower connecting frame 421. The third translation drive 434 is connected to the upper connecting frame 433, and the tray 431 is connected to the third translation drive 434. The third translation drive 434 can drive the upper connecting frame 433 to move back and forth. The upper connecting frame 433 is also connected to the slide 413 and moves up and down synchronously with the lower connecting frame 421. When the tray 431 needs to be used, the third translation drive 434 provides a driving force to the upper connecting frame 433 in the back-forward direction, so that multiple support rods 432 can be moved to different back and forth positions to store and retrieve materials.

[0034] In practical applications, the first lifting drive 412 can adopt a drive structure such as an electric guide rail, a cylinder, or a hydraulic cylinder, or it can use a motor with synchronous belt drive to drive the lifting frame to slide vertically on the column 411. Similarly, the first translation drive 422, the second translation drive 427, and the third translation drive 434 can adopt a drive structure such as an electric guide rail, a cylinder, or a hydraulic cylinder.

[0035] In some embodiments, the front and rear sides of the transfer pallet 428 are bent upwards respectively. After the transfer pallet 428 lifts the material upwards, the upward bending of its front and rear sides can restrict the material from moving in the front-back direction, making it less likely for the material to fall off the transfer pallet 428.

[0036] Within the lifting mechanism, multiple drive sources can be provided on each lifting frame, each providing a driving force to multiple lifting ends for vertical movement. In this embodiment, however, a drive source is provided within the lifting mechanism to drive the entire lifting frame to move vertically, thereby causing multiple lifting ends to move vertically simultaneously. Specifically, multiple lifting mechanisms are spaced apart along the left-right direction, and the sorting mechanism 4 is provided on the rear side of each of the multiple lifting mechanisms. Multiple storage layers 11 can be divided along the left-right direction to form multiple different storage partitions. In this case, one lifting mechanism and one sorting mechanism 4 correspond to one storage partition. Thus, after the first conveyor line 21 transfers the material to the corresponding storage partition, the corresponding lifting mechanism and sorting mechanism 4 transfer the material to the storage layer 11 within that storage partition, enabling faster and more efficient partitioned management of materials and enhancing practicality.

[0037] The lifting mechanism includes a drive source that moves the stop rod 31 up and down. Specifically, the lifting mechanism includes a second lifting drive 32, which is connected to the storage rack 1. The stop rod 31 is connected to the second lifting drive 32, which can move the stop rod 31 up and down. In practical applications, to improve the stability of the stop rod 31, a first guide rod can be connected to the storage rack 1, and a first guide sleeve can be connected to the stop rod 31. The first guide rod and the first guide sleeve cooperate to form a sliding constraint in the up and down direction, which makes the movement of the stop rod 31 more stable. The second lifting drive 32 provides a driving force for the stop rod 31 to move up and down. When the plate moves on the first conveyor line 21 and is moved into place, the second lifting drive 32 drives the stop rod 31 to move upward so that it protrudes from the conveying surface, thereby blocking the continued movement of the plate. After the plate is moved out, the second lifting drive 32 drives the stop rod 31 to move downward so that it is retracted below the conveying surface, without interfering with the continued movement of the next plate.

[0038] Within the lifting mechanism, multiple drive sources can be installed on each lifting frame, each providing a driving force to multiple lifting ends for vertical movement. In this embodiment, however, a single drive source is installed within the lifting mechanism to move the entire lifting frame vertically, thereby causing multiple lifting ends to move vertically simultaneously. Specifically, for example… Figure 4 and Figure 5 As shown, the lifting mechanism includes a third lifting drive 331, which is connected to the storage rack 1 at a position behind the first conveyor line 21. The lifting rack includes a first connecting rod 341 and lifting rods 342. The first connecting rod 341 is connected to the third lifting drive 331, which can drive the first connecting rod 341 to move up and down. Multiple lifting rods 342 are connected to the first connecting rod 341, and each lifting rod 342 extends forward into multiple clearance gaps to form multiple lifting ends. The third lifting drive 331 is located at a position behind the first conveyor line 21 on the storage rack 1. The first connecting rod 341 connects multiple lifting rods 342 into a single unit, using the multiple lifting rods 342 as lifting ends. In use, the third lifting drive 331 provides a driving force to the multiple lifting rods 342 in the up-down direction through the first connecting rod 341.

[0039] To enhance the structural stability of the lifting frame, such as Figure 6 and Figure 7As shown, in this embodiment, the lifting mechanism further includes a fourth lifting drive 332, which is connected to the storage rack 1 at a position in front of the first conveyor line 21. The lifting frame also includes a second connecting rod 343. Multiple lifting rods 342 protrude forward from the first conveyor line 21 and are connected to the second connecting rod 343. At least one lifting rod 342 protruding forward from the first conveyor line 21 is connected to the fourth lifting drive 332. The fourth lifting drive 332 is positioned in front of the storage rack 1 at the position in front of the first conveyor line 21, and the second connecting rod 343 is also connected to the front of the multiple lifting rods 342. Thus, the first connecting rod 341 and the second connecting rod 343 connect the multiple lifting rods 342 into a lifting frame with higher structural strength. The fourth lifting drive 332 and the third lifting drive 331 provide driving force for the lifting frame to move vertically from the front and rear sides respectively, making the lifting frame more stable during movement.

[0040] The second lifting drive 32, the third lifting drive 331 and the fourth lifting drive 332 are all used to provide driving force for movement in the up and down direction. They have various structural forms, such as cylinders, hydraulic cylinders or electric lead screws.

[0041] The storage layer 11 on the storage rack 1 can be a plate connected to the storage rack 1, with slots made in the plate to form a first gap, or it can be multiple fixed rods connected to the storage rack 1 in the left-right direction, with a first gap between two adjacent fixed rods, and multiple fixed rods located on the same plane form the storage layer 11.

[0042] The present invention also includes a second conveyor line 22, which is located below the first conveyor line 21. The second conveyor line 22 has third gaps respectively positioned opposite to the plurality of second gaps. The conveying direction of the second conveyor line 22 is opposite to that of the first conveyor line 21. The first conveyor line 21 is used for loading and storing the sheet metal. When the sheet metal needs to be removed, it can be transferred from the storage area to the second conveyor line 22, which then conveys the sheet metal outwards. This achieves separate conveying for storing and retrieving the sheet metal.

[0043] The first conveyor line 21 can be two belt conveyors spaced apart in the front-to-back direction, with the required second gap formed by the gap between the two belt conveyors. In this embodiment, the first conveyor line 21 is a first roller conveyor, and the second gap is formed by two adjacent conveying rollers within the first roller conveyor. The first roller conveyor has multiple rotatable conveying rollers, and the second gap is formed in the space between two conveying rollers, allowing the stop bar 31 or lifting end to protrude upwards or retract downwards from the conveying surface between the two conveying rollers. Similarly, the second conveyor line 22 can also be a second roller conveyor, with the third gap formed by two adjacent conveying rollers within the second roller conveyor.

[0044] A sorting method using the above-described strip sorting system includes the following steps: the baffle 31 protrudes upward from a second gap onto the conveying surface and blocks the material on the conveying surface; a plurality of lifting ends protrude upward from a plurality of second gaps onto the conveying surface and lift the material away from the conveying surface; the bracket 431 moves above the conveying surface; a plurality of support rods 432 move below the material; the plurality of lifting ends retract downward below the conveying surface; and the bracket 431 drives the material away from the first conveying line 21.

[0045] This sorting method is used to remove materials from the first conveyor line 21. Specifically, the first conveyor line 21 can first transfer the plates to the corresponding storage positions on the storage rack 1, and then the lifting mechanism and the sorting mechanism can remove the plates for storage. Multiple plates can be operated at the same time, which greatly improves the sorting efficiency of the plates and thus improves production efficiency.

[0046] A sorting method using the above-described strip sorting system includes the following steps: on the same storage layer 11, the transfer frame 426 moves below the storage layer 11, the tray 431 moves above the storage layer 11, a plurality of transfer trays 428 pass through a plurality of first gaps and lift the materials on the plurality of trays 431 upwards, the trays 431 move away from the storage layer 11, and the transfer frame 426 moves downwards and places the materials on the storage layer 11.

[0047] This sorting method is used to store materials at the required height and depth on the storage rack 1. Specifically, the materials can be moved to the storage layer 11 where they need to be placed first, and then placed in different positions of the storage layer 11 in the front-back direction, thereby improving the flexibility of material placement.

[0048] A sorting method using the above-described strip sorting system includes the following steps: In the same storage layer 11, the transfer frame 426 moves to below the storage layer 11, multiple transfer trays 428 pass upward through multiple first gaps and lift the material on the storage layer 11 upward, the bracket 431 moves to above the storage layer 11, multiple support rods 432 move to below the material, the multiple transfer trays 428 move downward and place the material on the multiple support rods 432, and the bracket 431 moves the material away from the storage frame 1.

[0049] This sorting method is used to remove materials from storage racks 1 at different heights and depths. Specifically, it can move to the storage layer 11 where the material to be removed is located, and then remove the materials arranged in the front-back direction on the storage layer 11 as needed, which greatly improves the flexibility of material removal.
