Sorting equipment for centering and aligning plates

Abstract

The sorting equipment for centering and aligning the plates comprises a longitudinal conveying belt and is further provided with a sorting warehouse, a warehouse outlet area and a suction cup, and a positioning block and a positioning block driving mechanism are arranged above the longitudinal conveying belt. The positioning block driving mechanism drives the positioning block to move front and back to sequentially block the multiple plates conveyed by the longitudinal conveying belt, so that the multiple plates are longitudinally positioned in sequence, and the multiple plates of the same order are sequentially fed into the sorting library in a centered and aligned state. Due to the fact that the multiple plates of the same order are sequentially fed into the sorting library in the centrally-aligned state, the short plates are located in the center, and when the suction cup centrally sucks up the aligned plates in the order in the sorting library, the suction cup can cover the short plates. As the sucker adsorbs the plate in a centered mode, the distance between the sucker and the front end and the rear end of the long plate is moderate, the long plate can be effectively prevented from drooping, and the situation that the rear end of the long plate droops due to the fact that the adsorption position is too front is avoided.

Description

Technical Field

[0001] This utility model relates to sheet material sorting equipment, specifically to a sorting equipment for center-aligning sheet materials. Background Technology

[0002] Sheet metal sorting equipment is used to sort sheets from different orders. It features a longitudinal conveyor belt running in both directions, a sorting bin, and an outbound area, and is equipped with suction cups. The longitudinal conveyor belt sequentially transports multiple sheets to its front end. The suction cups, based on the order to which each sheet belongs, sequentially deliver multiple sheets to the corresponding positions in the sorting bin, grouping sheets belonging to the same order together for sorting. Once a complete set of sheets for an order is collected (i.e., "complete set"), the suction cups remove the set from the sorting bin and deliver it to the outbound area. The longitudinal conveyor belt typically moves the front ends of each sheet to the same position during transport; that is, the suction cups deliver multiple sheets from the same order into the sorting bin sequentially with their front ends aligned. The boards in the same order may have different lengths, and for cost reasons, suction cups are generally made as short as possible. This leads to the following problems when the suction cups remove the complete set of boards: the short boards are positioned relatively far forward because their front ends are aligned. If the suction cup is centered, it may not be able to cover these short boards; if the suction cup is positioned far forward, it will be far from the back end of the long boards, and the back end of the long boards is prone to drooping. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a sorting device for centering and aligning sheet materials. When the suction cups take out the complete set of sheet materials, they can cover the short sheet materials and effectively prevent the long sheet materials from sagging.

[0004] The inventors discovered that by installing positioning blocks and a positioning block driving mechanism along the longitudinal conveyor belt, and using the positioning block driving mechanism to move the positioning blocks back and forth to block the boards conveyed by the longitudinal conveyor belt, multiple boards from the same order can be fed into the sorting warehouse in a centered, aligned state. In this case, the shorter boards will be in the center position. When the suction cup picks up the complete set of boards from the sorting warehouse, it can cover the shorter boards. Because the suction cup uses a centered suction method, the distance between it and the front and rear ends of the longer boards is moderate, effectively preventing the longer boards from sagging and avoiding the situation where the rear end of the longer board sags due to the suction position being too far forward.

[0005] Initially, the inventors chose a roller conveyor belt as the longitudinal conveyor belt. Because there were gaps between the rollers, they installed a positioning block drive mechanism and positioning blocks below the roller conveyor belt. The positioning block drive mechanism moved the positioning blocks back and forth to the corresponding positions, then extended upwards through the gaps between the rollers to block the sheet material, thus achieving the positioning of the sheet material. However, in practical applications, it was found that this design had limitations. Because the positioning blocks had to move to a specific gap between the rollers to extend upwards and block the sheet material, this meant that the positioning blocks had to be designed to rise from a fixed position, and their rising position could not be freely changed as needed.

[0006] To solve the above-mentioned technical problems, this utility model provides a sorting device for centering and aligning sheet materials. The sorting device includes a longitudinal conveyor belt running in the front-to-back direction, a sorting bin, an outbound area, and suction cups for moving the sheet materials. The longitudinal conveyor belt sequentially transports multiple sheet materials from different orders to the front of the longitudinal conveyor belt. The suction cups sequentially feed the multiple sheet materials into the sorting bin for sorting, ensuring that sheet materials from the same order are arranged horizontally side-by-side. The complete sets of sheet materials from the sorting bin are then sent to the outbound area. Above the longitudinal conveyor belt, there is a positioning block and a positioning block driving mechanism. The positioning block driving mechanism drives the positioning block to move back and forth, successively blocking the multiple sheet materials transported by the longitudinal conveyor belt, thereby sequentially positioning the multiple sheet materials vertically. This ensures that multiple sheet materials from the same order are center-aligned and sequentially fed into the sorting bin. The suction cups centrally pick up the complete sets of sheet materials from the sorting bin and send them to the outbound area.

[0007] Furthermore, the longitudinal conveyor belt and the sorting bin are located on the same side of the suction cup, and / or the sorting bin and the outbound area are located on the same side of the suction cup; a lateral drive mechanism is provided, which drives the suction cup to move laterally to send multiple pieces of board conveyed by the longitudinal conveyor belt into the sorting bin for sorting, and / or drives the suction cup to move laterally to send the complete set of board pieces in the sorting bin to the outbound area.

[0008] Furthermore, the longitudinal conveyor belt and the sorting warehouse are arranged vertically side by side, and / or the sorting warehouse and the outbound area are arranged vertically side by side; a vertical drive mechanism is provided, which drives the suction cups to move vertically to send multiple pieces of board conveyed by the longitudinal conveyor belt into the sorting warehouse for sorting, and / or drives the suction cups to move vertically to send the board pieces in the sorting warehouse that have been ordered to the outbound area.

[0009] Furthermore, a transverse conveying mechanism is provided at the front of the longitudinal conveyor belt. The transverse conveying mechanism conveys the positioned boards laterally, so that the positioned boards are arranged side by side. The suction cups pick up these side by side boards from the transverse conveying mechanism and send them into the sorting warehouse for sorting.

[0010] Furthermore, the longitudinal conveyor belt is specifically a roller conveyor belt, and the transverse conveying mechanism is a transverse conveyor belt located between two adjacent rollers of the longitudinal conveyor belt.

[0011] Furthermore, a lifting mechanism is provided, which drives the transverse conveyor mechanism to move upward to lift the positioned sheet material away from the longitudinal conveyor belt. The transverse conveyor mechanism then transversely conveys the sheet material that has been lifted away from the longitudinal conveyor belt.

[0012] Furthermore, an obstacle avoidance mechanism is provided. When the lifting mechanism drives the lateral conveying mechanism to move upward, the obstacle avoidance mechanism drives the positioning block to move upward to avoid obstacles.

[0013] Furthermore, a lateral positioning element is provided to laterally block the sheet material conveyed by the lateral conveying mechanism, thereby laterally positioning it.

[0014] Furthermore, there are several transverse positioning components arranged side by side, which are normally in a retracted state; a transverse stop drive mechanism is provided, which drives the movement of several transverse positioning components to block the several plates conveyed by the transverse conveying mechanism.

[0015] Furthermore, it includes a conveyor belt drive mechanism that drives the longitudinal conveyor belt, a control switch that controls the suction cup to generate suction force, and a controller that controls the conveyor belt drive mechanism, the control switch, and the positioning block drive mechanism.

[0016] Because the positioning block drive mechanism moves the positioning block back and forth sequentially to position multiple boards, multiple boards from the same order are fed into the sorting warehouse in a centered, aligned state. The shorter boards are thus positioned in the center. When the suction cup picks up the complete set of boards from the sorting warehouse, it covers the shorter board. Since the suction cup uses a centered suction method, its distance from the front and rear ends of the longer boards is moderate, effectively preventing the longer boards from sagging. This avoids the rear end of the longer board sagging due to the suction position being too far forward. Because the positioning block is positioned above the board conveyor belt rather than passing underneath it, it does not interfere with the conveyor belt and can move freely back and forth.

[0027] The present invention will be further described in detail below with reference to specific embodiments.

[0028] See sheet metal sorting equipment Figure 1 The system includes a frame 100. An inbound conveyor belt 1 is installed at the bottom of the frame 100; an outbound conveyor belt 4 is installed in the middle; and the top serves as a sorting warehouse 3, on which multiple board placement plates 31 are installed side-by-side. In this embodiment, the sorting warehouse 3 is a three-layer warehouse, so only three board placement plates 31 are shown in the figure. Both the inbound conveyor belt 1 and the outbound conveyor belt 4 are roller conveyors and are longitudinal conveyors in the front-to-back direction. The front part 11 of the inbound conveyor belt 1, the rear part 43 of the outbound conveyor belt 4, and the sorting warehouse 3 are vertically aligned. The board sorting equipment includes an inbound drive motor 101 and an outbound drive motor 401, both of which serve as conveyor belt drive mechanisms. The inbound drive motor 101 drives the inbound conveyor belt 1, and the outbound drive motor 401 drives the outbound conveyor belt 4. A board handling mechanism 2 is located on the right side of the front part 11 of the inbound conveyor belt 1. A board barcode scanner 131 is located at the rear part 13 of the inbound conveyor belt 1. The board sorting equipment includes a controller (not shown in the figure), which controls the inbound drive motor 101, the outbound drive motor 401, the board handling mechanism 2, and the board barcode scanner 131, and controls the above four to work together to complete the sorting operation. The specific workflow is as follows:

[0029] See Figure 1Workers place multiple pieces of board 9 with identification codes from different orders (taking orders A, B, and C as examples below) sequentially onto the rear 13 of the inbound conveyor belt 1 of the board sorting equipment. The inbound drive motor 101 drives the inbound conveyor belt 1 to move the multiple pieces of board 9 forward to the front 11 of the inbound conveyor belt 1. During this process, the board barcode scanner 131 scans the identification codes of multiple pieces of board 9 to identify the length of the board 9 and the order to which the board 9 belongs. The board handling mechanism 2 moves the multiple pieces of board 9 from the front 11 of the inbound conveyor belt 1 to the sorting warehouse 3 for sorting. Specifically, the board 9 required for order A is placed in the upper layer of the sorting warehouse 3, the board 9 required for order B is placed in the middle layer of the sorting warehouse 3, and the board 9 required for order C is placed in the lower layer of the sorting warehouse 3, with the boards 9 of the same order arranged horizontally side by side. Once the required sheet material 9 for an order is collected in a complete set (i.e., "complete set"), for example, the required sheet material 9 for order A is collected in a complete set, the sheet material handling mechanism 2 takes the set of sheet material 9 out of the sorting warehouse 3 and sends it to the outbound conveyor belt 4. The outbound conveyor belt 4 serves as the outbound area. The outbound drive motor 401 drives the outbound conveyor belt 4 to send the set of sheet material 91 forward to the front 41 of the outbound conveyor belt 4, where the staff packs the set of sheet material 9 into boxes.

[0030] See Figure 2 Between each pair of adjacent rollers 10 at the front part 11 of the inbound conveyor belt 1, there are 11 horizontal conveyor belts 61 and 11 horizontal drive motors 601 driving the horizontal conveyor belts 61. The horizontal conveyor belts 61 are 1 cm lower than the rollers 10 of the inbound conveyor belt 1, and their right side 612 extends horizontally to the right side of the front part 11 of the inbound conveyor belt 1. Below the 11 horizontal conveyor belts 61, there is a first vertical electric push rod 62, and a first mounting bracket (not shown in the figure due to the perspective) is provided on the top of the first vertical electric push rod 62. The 11 horizontal conveyor belts 61 are mounted on the first mounting bracket. On the right side of the horizontal conveyor belts 61, there are two horizontal positioning mechanisms 64 arranged side by side. The horizontal positioning mechanisms 64 are normally flush with the horizontal conveyor belts 61. The controller controls the horizontal drive motors 601 and the first vertical electric push rods 62, and also controls the horizontal positioning mechanisms 64, controlling the coordination of the above three. When the first sheet material 91 is conveyed to the front 11 of the inbound conveyor belt 1: the first vertical electric push rod 62 acts as a lifting mechanism, driving the horizontal conveyor belt 61 to move upwards by 10cm, lifting the first sheet material 91 that has been conveyed to the front 11 of the inbound conveyor belt 1 until it leaves the inbound conveyor belt 1, as shown. Figure 3Eleven horizontal conveyor belts 61, acting as a horizontal conveying mechanism, are driven by eleven horizontal drive motors 601 to jointly convey the first board 91, which has been raised and moved away from the receiving conveyor belt 1, to the right side of the receiving conveyor belt 1 for 5 seconds. Simultaneously, the right-side horizontal positioning mechanism 64 rises above the horizontal conveyor belts 61, horizontally blocking the first board 91 being conveyed to the right side of the receiving conveyor belt 1, thus horizontally positioning the first board 91. After the horizontal conveyor belts 61 have completed the conveying of the first board 91, the first vertical electric push rod 62 drives the horizontal conveyor belts 61 to descend and reset, preventing the horizontal conveyor belts 61 from interfering with the conveying of the next board 92. When the next board 92 is conveyed to the front 11 of the receiving conveyor belt 1, the first vertical electric push rod 62 again drives the horizontal conveyor belts 61 to raise the board 92, and the eleven horizontal drive motors 601 again drive the eleven horizontal conveyor belts 61 to jointly convey this board 92 horizontally to the right side of the receiving conveyor belt 1. Figure 4 The left-hand lateral positioning mechanism 64 performs lateral positioning on the sheet metal 92, which will not be elaborated here. After lateral positioning, the sheet metal 92 is placed side by side with the first sheet metal 91 on the lateral conveyor belt 61. When the sheet metal handling mechanism 2 moves the sheet metal 9 from the front 11 of the inbound conveyor belt 1, see... Figure 6 The two side-by-side boards 91 and 92 are lifted from the transverse conveyor belt 61 and sent to the sorting warehouse 3 (see Figure 7 Sorting in the middle.

[0031] See Figure 2 The two lateral positioning mechanisms 64 have identical structures; the following description uses one as an example. The lateral positioning mechanism 64 includes a second vertical electric push rod 641. A second mounting bracket 642 is mounted on the top of the second vertical electric push rod 641. Eleven lateral positioning posts 643 are mounted on the second mounting bracket 642. The eleven lateral positioning posts 643 are located behind the eleven lateral conveyor belts 61, flush with the eleven lateral conveyor belts 61, and are in a retracted state. The controller controls the connection to the second vertical electric push rod 641. See... Figure 3 When the first vertical electric push rod 62 drives the transverse conveyor belt 61 to move upward by 10cm, lifting the first plate 91, the second vertical electric push rod 641 acts as a horizontal stop drive mechanism. The controller controls the second vertical electric push rod 641 of the right-hand transverse positioning mechanism 64 to drive the transverse positioning post 643 to move upward by 15cm, thereby raising the transverse positioning post 643 above the transverse conveyor belt 61. When the transverse conveyor belt 61 transversely transports the first plate 91 to the right side of the inbound conveyor belt 1, the transverse positioning post 643 of the right-hand transverse positioning mechanism 64 acts as a transverse positioning element, transversely blocking the first plate 91, thereby transversely positioning the plate 91. See Figure 4Similarly, when the transverse conveyor belt 61 lifts the next sheet 92, the controller controls the second vertical electric push rod 641 of the left-hand transverse positioning mechanism 64 to drive the transverse positioning column 643 to rise 15cm, thus making the transverse positioning column 643 higher than the transverse conveyor belt 61. When the transverse conveyor belt 61 transversely transports the next sheet 92, the transverse positioning column 643 of the left-hand transverse positioning mechanism 64 transversely blocks the sheet 92 transported by the transverse conveyor belt 61, thereby performing transverse positioning of the sheet 92. After completing the transverse positioning of the two sheets 91 and 92, the controller controls the second vertical electric push rod 641 of the two transverse positioning mechanisms 64 to drive the transverse positioning column 643 to reset, so as to prevent the transverse positioning column 643 from affecting the sheet transporting mechanism 2 in transporting sheet 9.

[0032] See sheet material handling mechanism 2 Figure 5 The system includes a vertical module mounting bracket 20, on which a vertical conveying linear module 21 is mounted. A horizontal module mounting plate 22 is mounted on the vertical conveying linear module 21. A horizontal conveying linear module 23 is mounted on the horizontal module mounting plate 22. A suction cup mounting plate 24 is mounted on the horizontal conveying linear module 23. Two negative pressure suction cups 25 are mounted below the suction cup mounting plate 24, one in front and one behind. The sheet material conveying mechanism 2 also includes a negative pressure generator (not shown in the figure) that provides negative pressure to the suction cups 25. Each suction cup 25 has five independent negative pressure adsorption parts 250 arranged side-by-side. Each negative pressure adsorption part 250 is equipped with a negative pressure valve 255 (see figure). Figure 6 The negative pressure valve 255 acts as a control switch. The controller controls the connection to the negative pressure valve 255, keeping it closed under normal conditions. In this state, the negative pressure adsorption unit 250 is not connected to the negative pressure generator, and therefore no suction is generated. See Figure 6 The suction cup 25 is located on the right side of the front part 11 of the inbound conveyor belt 1. The first and second negative pressure adsorption parts 251 and 252 of the suction cup 25 from left to right are respectively aligned with the left side area of ​​the horizontal positioning posts 643 of the two horizontal positioning mechanisms 64. The plates 91 and 92, which are laterally positioned by the horizontal positioning posts 643, are exactly located in the above-mentioned area. That is to say, the first and second negative pressure adsorption parts 251 and 252 of the suction cup 25 are respectively aligned with the two plates 92 and 91 after horizontal positioning. The controller controls the vertical conveying linear module 21 and the horizontal conveying linear module 23, and controls the vertical conveying linear module 21, the horizontal conveying linear module 23 and the negative pressure valve 252 to work together to move the two plates 91 and 92 after horizontal positioning into the sorting warehouse 3 for sorting. The specific control process is as follows:

[0033] See Figure 6The vertical transport linear module 21 acts as a vertical drive mechanism, driving the suction cup 25 downwards to its lower end. In this state, the first and second negative pressure adsorption parts 251 and 252 of the suction cup 25 are precisely attached to the surfaces of the two plates 92 and 91. The negative pressure valves 255 corresponding to these two negative pressure adsorption parts 251 and 252 open, allowing the negative pressure adsorption parts 251 and 252 to connect to the negative pressure generator and generate negative pressure to adsorb plates 92 and 91. If these two plates 91 and 92 both belong to order A, and order A contains a total of 5 plates 9, then... Figure 1 Of these, three have already entered the upper level of sorting warehouse 3, leaving only the two storage locations on the right side of the upper level of sorting warehouse 3. See Figure 7 The vertical transport linear module 21 drives the suction cup 25 to lift the two adsorbed boards 91 and 92 upwards to the corresponding height on the upper layer of the sorting warehouse 3. The horizontal transport linear module 23, acting as a lateral drive mechanism, drives the suction cup 25 to move the two adsorbed boards 91 and 92 laterally to the left into the remaining two storage positions on the upper layer of the sorting warehouse 3. The negative pressure valves 255 corresponding to the first and second negative pressure adsorption parts 251 and 252 close, and the suction cup 25 places the two boards 91 and 92 on the upper layer of the sorting warehouse 3, completing the sorting of these two boards 91 and 92. Since the five boards 9 required for order A are complete, the board transport mechanism 2 begins to remove the boards 9 from order A: see... Figure 8 The horizontal transport linear module 23 drives the suction cup 25 to move laterally to the left end of the horizontal transport linear module 23, so that the five negative pressure adsorption parts 250 of the suction cup 25 are respectively aligned with the five pieces of board 9 of order A. The negative pressure valves 255 corresponding to the five negative pressure adsorption parts 250 are all opened, so that the five negative pressure adsorption parts 250 generate negative pressure and adsorb the five pieces of board 9 respectively. The horizontal transport linear module 23 drives the suction cup 25 to move the five adsorbed pieces of board 9 laterally to the right end of the horizontal transport linear module 23. The vertical transport linear module 21 drives the suction cup 25 to move the pieces of board 9 downward to the height corresponding to the outbound conveyor belt 4. The horizontal transport linear module 23 drives the suction cup 25 to move the five adsorbed pieces of board 9 laterally to the left to above the outbound conveyor belt 4. Figure 9All negative pressure valves 255 are closed, and suction cups 25 place the five boards 9 of order A onto the outbound conveyor belt 4. The outbound drive motor 401 drives the outbound conveyor belt 4 to transport the five boards 9 of order A to the front 41 of the outbound conveyor belt 4. If, after lateral positioning, one of the two boards 91 and 92 belongs to order A and the other to order B, then the board handling mechanism 2 first places board 91 of order A on the upper layer of the sorting warehouse 3, and then places board 92 of order B on the middle layer of the sorting warehouse 3. The rest is the same and will not be elaborated further. In the prior art, the inbound conveyor belt 1 and the sorting warehouse 3 are located on the left and right sides of the board handling mechanism 2, respectively. The board handling mechanism needs to use a rotational movement method to handle the boards 9, and the boards 9 will be subjected to centrifugal force throughout the process. In contrast, in the board sorting equipment of this application, the inbound conveyor belt 1 and the sorting bin 3 are both located to the left of the board handling mechanism 2. The board handling mechanism 2 uses a lateral movement to handle the board 9. During the lateral movement, the board 9 is only subjected to lateral inertial force during the acceleration and deceleration phases, and is not subjected to lateral inertial force during the uniform motion phase. It can be seen that this application can reduce the time that the board 9 is subjected to force, thereby reducing the risk of the board 9 falling off, and the board 9 is not easy to fall off.

[0034] See Figure 8 Because the lengths of the boards 9 vary and the coverage area of ​​the suction cup 25 is limited, if all the boards 9 are aligned front-end as in existing technology, the suction cup 25 may not be able to pick up the shorter boards 9 when it is centered during removal, and if the suction cup 25 is positioned too far forward during removal, the rear end of the longer boards 9 may sag due to its greater distance from the rear end. Therefore, see... Figure 10 This sheet metal sorting equipment has an installation plate 50 above the front part 11 of the inbound conveyor belt 1. The installation plate 50 is mounted on the frame 100. A centering linear module 52 in the front-rear direction is installed on the installation plate 50. An electric push rod mounting plate 521 is mounted on the centering linear module 52. A downward-facing third electric push rod 53 is mounted on the electric push rod mounting plate 521. A positioning block 51 is installed at the lower end of the third electric push rod 53. The controller controls the connection between the centering linear module 52 and the third electric push rod 53. During the process of the inbound conveyor belt 1 conveying the first sheet metal 91 to the front part 11 of the inbound conveyor belt 1, the sheet metal scanner 131 (see...) Figure 1The system scans the identification code of the first sheet material 91 to obtain its length information. The centering linear module 52 acts as the positioning block drive mechanism. The controller first controls the centering linear module 52 to drive the third electric push rod 53 and the positioning block 51 to move back and forth to a suitable position based on the length of the first sheet material 91. Then, the controller controls the third electric push rod 53 to drive the positioning block 51 to extend downwards and longitudinally block the first sheet material 91 on the top surface of the inbound conveyor belt 1, thus longitudinally positioning the first sheet material 91 and stopping it in the center of the front part 11 of the inbound conveyor belt 1. For example, if the longitudinal length of the front part 11 of the inbound conveyor belt 1 is 200cm, and the length of the first sheet material 91 is 100cm, and the positioning block 51 is exactly in the middle of the front part 11 of the inbound conveyor belt 1, then the controller controls the centering linear module 52 to drive the third electric push rod 53 and the positioning block 51 to move forward 50cm, so that the positioning block 51 can precisely block the first sheet material 91 in the center of the front part 11 of the inbound conveyor belt 1. A pressure sensor (not shown in the figure) is installed on the rear wall of the positioning block 51. The controller is connected to the pressure sensor. When the positioning block 51 blocks the first plate 91, the first plate 91 will impact the pressure sensor forward. At this time, the controller determines that the positioning block 51 has blocked the first plate 91, and then controls the storage drive motor 101 to stop working, waiting for the transverse conveyor belt 61 to transport the longitudinally positioned first plate 91 laterally to the right side of the storage conveyor belt 1. The third vertical electric push rod 53 acts as a clearance mechanism. Before the transverse conveyor belt 61 transports the first plate 91, the controller controls the first vertical electric push rod 62 (see Figure 3 The controller drives the horizontal conveyor belt 61 to move upwards, lifting the first sheet material 91. To prevent the positioning block 51 from interfering with the upward movement of the horizontal conveyor belt 61, the controller simultaneously controls the third vertical electric push rod 53 to drive the positioning block 51 upwards to avoid obstruction. After the horizontal conveyor belt 61 completes the horizontal transport of the first sheet material 91, the controller controls the inbound drive motor 101 to continue working, driving the inbound conveyor belt 1 to transport the next sheet material 92 (see...). Figure 1 The material is sent to the front 11 of the inbound conveyor belt 1, and the centering linear module 52 continues to drive the positioning block 51 to longitudinally block the next piece of material 92, positioning the material 92 longitudinally so that it stops at the center position of the front 11 of the inbound conveyor belt 1. Then, the transverse conveyor belt 61 transversely conveys the longitudinally positioned material 92 to the right side of the inbound conveyor belt 1, so that the two longitudinally positioned materials 91 and 92 are laterally side by side. This process is repeated, with the positioning block 51 longitudinally positioning all the materials 9 of all orders, so that all the materials 9 of all orders are sent into the sorting warehouse 3 in a centered and aligned state. Figure 4 and Figure 7Therefore, the short board (i.e., the first board 91) is positioned in the center. When the board handling mechanism 2 is outgoing, the two suction cups 25 centrally pick up the complete set of boards 9 from the sorting warehouse 3 and send them to the outgoing conveyor belt 4. The two suction cups 25 can cover the short board. Because the two suction cups 25 adsorb the board 9 in a centrally positioned manner, the distance between the suction cups 25 and the front and rear ends of the long board (i.e., board 92) is relatively moderate, effectively preventing the long board from sagging and avoiding the situation where the rear end of the long board sags due to the suction position being too far forward. See... Figure 10 Since the positioning block 51 is located above the inbound conveyor belt 1 rather than passing through the inbound conveyor belt 1 from below, it does not interfere with the inbound conveyor belt 1 and can move freely back and forth.

[0035] In other embodiments, the rear of the inbound conveyor belt of the board sorting equipment is connected to the existing board processing equipment. Workers place the boards to be processed onto the board processing equipment, which then processes the boards and sends them to the rear of the inbound conveyor belt of the board sorting equipment. The board sorting equipment then sorts the processed boards. Further details are omitted. The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention still fall within the scope of patent protection.
