Plate sorting equipment with high single-time carrying efficiency

Abstract

According to the plate sorting equipment with the high single-time carrying efficiency, the longitudinal conveying belt is arranged, the sorting library and the plate carrying mechanism are further arranged, the longitudinal conveying belt conveys a plurality of plates of different orders to the front portion of the longitudinal conveying belt in sequence, and the sequence adjusting mechanism is arranged on the longitudinal conveying belt; the plate carrying mechanism carries other order plates located among the same order plates away from the longitudinal conveying belt so that the same order plates can be adjacent in the front-back direction, and the plate carrying mechanism carries the same order plates adjacent in the front-back direction into the sorting library to be sorted at a time. Due to the fact that the multiple plates belong to the same order, the multiple plates can be put down at the same time when the plate carrying mechanism moves to the position, corresponding to the order, in the sorting library, the single-time carrying task can be completed only through one-time movement, and the single-time carrying efficiency is high.

Description

Technical Field

[0001] This utility model relates to sheet material sorting equipment, specifically to sheet material sorting equipment with high single-pass handling efficiency. 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 warehouse, an outbound area, and a sheet handling mechanism. The longitudinal conveyor belt sequentially transports multiple sheets to its front end. The sheet handling mechanism, based on the order to which each sheet belongs, moves the sheets sequentially to the corresponding positions in the sorting warehouse, 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 sheet handling mechanism removes the set from the sorting warehouse and moves it to the outbound area for shipment. Some sheet metal sorting equipment designs its sheet handling mechanism to move two or three adjacent sheets from the conveyor belt into the sorting warehouse at once to improve handling efficiency. However, because the sheet transport sequence on the longitudinal conveyor belt is disordered, the sheet handling mechanism suffers from low efficiency per transport. For example, a board handling mechanism can handle two boards at a time. If the board conveying order is "Order A - Order B - Order A", then the board handling mechanism will first handle one board for "Order A" and one board for "Order B". In this case, the board handling mechanism needs to move to the position corresponding to "Order A" in the sorting warehouse to put down the first board, and then move to the position corresponding to "Order B" in the sorting warehouse to put down the second board. In other words, the board handling mechanism needs to make two moves to complete a single handling task, which is inefficient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a plate sorting device with high single-pass handling efficiency.

[0004] To solve the above-mentioned technical problems, the present invention provides a high-efficiency board sorting equipment, which includes a longitudinal conveyor belt in the front-to-back direction, a sorting warehouse, and a board handling mechanism for handling boards. The longitudinal conveyor belt delivers multiple boards from different orders to the front of the longitudinal conveyor belt in sequence. The board handling mechanism moves the multiple boards into the sorting warehouse for sorting in sequence. An ordering mechanism is provided on the longitudinal conveyor belt, which moves other boards from orders located between multiple boards of the same order away from the longitudinal conveyor belt so that the multiple boards of the same order are adjacent to each other. The board handling mechanism moves multiple adjacent boards of the same order into the sorting warehouse for sorting in one go.

[0005] Furthermore, the longitudinal conveyor belt is a roller conveyor belt, and the sequencing mechanism includes a lifting frame and a lifting drive mechanism. The lifting frame is set between two adjacent rollers of the longitudinal conveyor belt. The longitudinal conveyor belt sends other order boards located among multiple identical order boards to the position corresponding to the lifting frame. The lifting drive mechanism drives the lifting frame to lift the other order boards to leave the longitudinal conveyor belt, thereby removing the board from the longitudinal conveyor belt.

[0006] Furthermore, the lifting frame is a multi-layered frame.

[0007] Furthermore, there are multiple lifting frames arranged longitudinally side by side, and the lifting drive mechanism drives the multiple lifting frames to move synchronously and lift the same board together.

[0008] Furthermore, when the lifting mechanism drives the lifting frame to move downwards and reset, the lifting frame places the plate that has been moved off the longitudinal conveyor belt back onto the longitudinal conveyor belt.

[0009] Furthermore, including the outbound area, the board handling mechanism delivers the boards with complete sets of orders from the sorting warehouse to the outbound area.

[0010] Furthermore, the sheet material handling mechanism is an adsorption-type handling mechanism. The longitudinal conveyor belt and the sorting warehouse are located on the same side of the sheet material handling mechanism. The sheet material handling mechanism sends multiple adjacent sheets of the same order from the front of the longitudinal conveyor belt to the sorting warehouse for sorting.

[0011] Furthermore, the longitudinal conveyor belt and the sorting warehouse are arranged side by side, and the sheet material handling mechanism vertically sends multiple adjacent sheets of the same order into the sorting warehouse for sorting from the front of the longitudinal conveyor belt.

[0012] Furthermore, a transverse conveying mechanism is provided in front of the longitudinal conveyor belt. The transverse conveying mechanism sends out multiple identical order boards conveyed by the longitudinal conveyor belt laterally, so that the multiple identical order boards are arranged side by side. The board handling mechanism picks up these multiple boards arranged side by side from the transverse conveying mechanism and sends them to the sorting warehouse for sorting.

[0013] Furthermore, a conveyor belt drive mechanism is provided to drive the longitudinal conveyor belt, and a controller is provided to control and connect the conveyor belt drive mechanism, the sheet material handling mechanism, and the sequencing mechanism.

[0014] This utility model's board sorting equipment utilizes a sequencing mechanism to move other order boards located between multiple identical order boards away from the longitudinal conveyor belt, thus making multiple identical order boards adjacent to each other. The board handling mechanism then moves multiple identical order boards that are transported adjacent to each other into the sorting warehouse for sorting in one go. For example, the board handling mechanism can move two adjacent boards at once. If the board conveying order is "Order A - Order B - Order A", then the sequencing mechanism will engage the order B board located between two order A boards, thus making the two order A boards transported adjacent to each other. The board handling mechanism then moves the two adjacent order A boards into the sorting warehouse for sorting in one go. Since both boards belong to order A, the board handling mechanism can move to the corresponding "Order A" position in the sorting warehouse and put both boards down together. Only one movement is needed to complete a single handling task, resulting in high single-handled efficiency. Attached Figure Description

[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 set of boards 9 for an order is collected (i.e., "complete set"), for example, the required set of boards 9 for order A is collected, the board handling mechanism takes the set of boards 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 boards 91 forward to the front 41 of the outbound conveyor belt 4, where staff will pack the set of boards 9 into boxes.

[0030] See Figure 2 A sensor (not shown in the figure) is installed at the front part 11 of the inbound conveyor belt 1. In this embodiment, the sensor is a vision sensor. The controller is connected to the vision sensor, which detects whether the board 9 has been conveyed to the front part 11 of the inbound conveyor belt 1. This is prior art. 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 that drive 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 part 612 extends horizontally to the right side of the front part 11 of the inbound conveyor belt 1. A first vertical electric push rod 62 is provided below the 11 horizontal conveyor belts 61, and a first mounting bracket is provided on the top of the first vertical electric push rod 62 (not shown in the figure due to the viewing angle). The 11 horizontal conveyor belts 61 are mounted on the first mounting bracket. Two horizontal positioning mechanisms 64 are arranged side-by-side on the right side of the horizontal conveyor belt 61. Normally, the horizontal positioning mechanisms 64 are flush with the horizontal conveyor belt 61. A controller controls the horizontal drive motor 601 and the first vertical electric push rod 62, and also controls the horizontal positioning mechanisms 64, ensuring their coordinated operation. When the first piece of 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 upwards by 10cm to lift the first piece of material 91 from the front 11 of the inbound conveyor belt 1, as shown below. 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] The sheet material handling mechanism 2 is a negative pressure adsorption type handling mechanism, see Figure 5 It 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 section 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. 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 horizontal drive mechanism, drives the suction cup 25 to move the two adsorbed boards 91 and 92 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 9; All negative pressure valves 255 are closed. The suction cup 25 then places the 5 sheets 9 of order A onto the outfeed conveyor belt 4. The outfeed drive motor 401 drives the outfeed conveyor belt 4 to convey the 5 sheets 9 of order A to the front part 41 of the outfeed conveyor belt 4. If one of the two sheets 91 and 92 after lateral positioning belongs to order A and the other belongs to order B, then the sheet handling mechanism 2 first places the sheet 91 of order A on the upper layer of the sorting warehouse 3, and then places the sheet 92 of order B on the middle layer of the sorting warehouse 3. The same principle applies to the rest and will not be elaborated here. In the prior art, the infeed conveyor belt 1 and the sorting warehouse 3 are respectively located on the left and right sides of the sheet handling mechanism 2. The sheet handling mechanism needs to use a rotational movement method to handle the sheet 9, and the sheet 9 will be affected by centrifugal force throughout the process. In contrast, for the sheet sorting equipment of the present application, its infeed conveyor belt 1 and the sorting warehouse 3 are both located on the left side of the sheet handling mechanism 2. The sheet handling mechanism 2 uses a lateral movement method to handle the sheet 9. During the lateral movement, the sheet 9 is only affected by the lateral inertial force during the acceleration and deceleration stages, and will not be affected by the lateral inertial force during the uniform motion stage. Thus, it can be seen that the present application can reduce the force time of the sheet 9 and thereby reduce the risk of the sheet 9 falling, and the sheet 9 is not likely to fall.

[0034] See Figure 1 , if it is possible to ensure as much as possible that two adjacent sheets 9 on the infeed conveyor belt 1 belong to the same order (for example, both belong to order A), then after these two sheets 9 are laterally conveyed by the lateral conveyor belt 61 for lateral positioning, the sheet handling mechanism 2 picks up these two sheets 9 at one time and only needs to move to the position in the sorting warehouse 3 belonging to order A to put down these two sheets 9 together to complete the sorting of these two sheets 9, and the single handling efficiency is relatively high. For this reason, the present sheet sorting equipment has a sequencing mechanism 7 provided in the middle part 12 of the infeed conveyor belt 1. When there is a sheet 93 of another order mixed between two sheets 91 and 92 of the same order, the sequencing mechanism 7 can move the sheet 93 of the other order away from the infeed conveyor belt 1, so that the two sheets 91 and 92 of the same order are adjacent to each other. The sequencing mechanism 7 See Figure 10 , including a third vertical electric push rod 71. A lifting plate frame mounting plate 72 is installed on the top of the third vertical electric push rod 71, and a plurality of lifting plate frames 73 arranged side by side in the front and back are installed on the lifting plate frame mounting plate 72. The lifting plate frame 73 is a three-layer frame in the shape of a Chinese character "mu", and the height of each layer is 10 cm. Its top 730 (that is, the uppermost "door" part) extends upward from between two adjacent rollers 10 in the middle part 12 of the infeed conveyor belt 1 to the upper side of the infeed conveyor belt 1, and its top layer 731 is located below the infeed conveyor belt 1 and usually does not affect the conveyance of the sheet 9 by the infeed conveyor belt 1. The controller is controlled to connect the third vertical electric push rod 71. See Figure 1 And Figure 10When there are other orders' boards 93 between two boards 91 and 92 of the same order being conveyed on the inbound conveyor belt 1, for example: the board conveying order is order A - order B - order A, when the inbound conveyor belt 1 conveys the first board 91 (order A) to the front 11, the middle board 93 (order B) is exactly in the middle 12 of the inbound conveyor belt 1 and reaches the top 731 of the lifting rack 73, and the last board 92 (order A) is in the rear 13 of the inbound conveyor belt 1; see Figure 11 The third vertical electric push rod 71 acts as a lifting mechanism. The controller controls the third vertical electric push rod 71 to drive multiple lifting frames 73 to move upwards synchronously by 10cm. The top layer 731 of the multiple lifting frames 73 then collectively lifts the centrally located board 93 away from the inbound conveyor belt 1, thus removing board 93 from the inbound conveyor belt 1 and interrupting the sorting process of board 93. After board 93 is removed from the inbound conveyor belt 1, the two boards 91 and 92 belonging to order A will become adjacent to each other on the inbound conveyor belt 1. The middle layer 732 of the lifting frame 73 is located on the outer periphery of the conveying path of the inbound conveyor belt 1, and does not affect the conveying of board 9 by the inbound conveyor belt 1. See [link / description]. Figure 1 and Figure 4 Then, the horizontal conveyor belt 61 transports the first piece 91 from the front to the right side of the inbound conveyor belt 1. The inbound conveyor belt 1 continues to transport the boards forward, transporting the next piece 92 from the back to the front 11 of the inbound conveyor belt 1. The horizontal conveyor belt 61 then transports the piece 92 to the right. (See...) Figure 6 and Figure 7 The board handling mechanism 2 lifts both boards 91 and 92 at once. It only needs to move them to the location in the sorting warehouse 3 corresponding to order A to place both boards 91 and 92 together, thus completing the sorting of these two boards 9. The single-transfer efficiency is high. However, the workers do not continuously add boards 9; they occasionally stop (e.g., to use the restroom or to move the next batch of boards). During these stops, empty spaces appear on the inbound conveyor belt 1. See [link / details]. Figure 1 If the barcode scanner 131 at the front of the inbound conveyor belt 11 scans a piece of board 9, and fails to scan the next piece of board 9 before that piece of board 9 is delivered to the front of the inbound conveyor belt 11, then the controller determines that there is an empty space on the inbound conveyor belt 1. Therefore, it controls the third vertical electric push rod 71 to drive the lifting frame 73 to descend and reset, placing the board 93 that has been removed from the inbound conveyor belt 1 back onto the inbound conveyor belt 1. Figure 10 As shown, resume the sorting process for board 93. See Figure 12Since the lifting frame 73 is a three-layer frame, if the conveying order of the board 9 is order A - order B - order C - order A, then the lifting frame 73 will lift the board 96 of order B with the top layer 731 and lift the board 97 of order C with the middle layer 732, so that the two boards 9 of order A are adjacent to each other. This will not be elaborated here.

[0035] See Figure 1 and Figure 11 In other embodiments, the rear section 13 and the front middle section 11, 12 of the inbound conveyor belt 1 can be divided into two segments. The original inbound drive motor 101 (hereinafter referred to as the "first inbound drive motor") is replaced to drive the front middle section 11, 12 of the inbound conveyor belt 1, and a second inbound drive motor is added to drive the rear section 13 of the inbound conveyor belt 1. When there is order B material on the lifting frame 73 (e.g., Figure 11 When board 93 is being processed, if the board barcode scanner 131 at the rear 13 of the inbound conveyor belt 1 scans a board that also belongs to order B, the controller controls the first inbound drive motor 101 to drive the inbound conveyor belt 1 to move the board currently in the middle 12 of the inbound conveyor belt 1 forward, and at the same time controls the second inbound drive motor 102 to stop conveying the order B board on it, thus leaving an empty space in the middle 12 of the inbound conveyor belt 1. When the board that was originally in the middle 12 of the inbound conveyor belt 1 has been sent to the front 11 of the inbound conveyor belt 1, the controller controls the third vertical electric push rod 71 to drive the lifting frame 73 to move downwards to reset and put the order B board that has been removed from the inbound conveyor belt 1 back onto the inbound conveyor belt 1, restoring the board sorting process, thereby making the two boards belonging to order B adjacent to each other.

[0036] 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. The board processing equipment does not continuously transport boards to the rear of the inbound conveyor belt for extended periods; it occasionally stops (e.g., when there are many board processing projects or the process is time-consuming). At this time, empty spaces appear on the inbound conveyor belt. If the controller determines that there are empty spaces on the inbound conveyor belt, it controls the third vertical electric push rod to drive the lifting frame to descend and reset, placing the boards that have been removed from the inbound conveyor belt back onto it, resuming the sorting process for those boards.

[0037] 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 will still fall within the scope of patent protection.

The lifting drive mechanism drives the lifting frame to lift the other order boards to leave the longitudinal conveyor belt, thereby removing the boards from the longitudinal conveyor belt.

3. The sheet metal sorting equipment according to claim 2, characterized in that: The lifting frame is a multi-layer frame.

4. The sheet metal sorting equipment according to claim 2, characterized in that: There are multiple lifting frames arranged longitudinally side by side. The lifting drive mechanism drives the multiple lifting frames to move synchronously and lift the same piece of board together.

5. The sheet metal sorting equipment according to claim 2, characterized in that: When the lifting mechanism drives the lifting frame to move downwards and resets, the lifting frame puts the plate that has been moved off the longitudinal conveyor belt back onto the longitudinal conveyor belt.

6. The sheet metal sorting equipment according to claim 1, characterized in that: Including the outbound area, the board handling mechanism delivers the boards with complete sets of orders from the sorting warehouse to the outbound area.

7. The sheet metal sorting equipment according to claim 1, characterized in that: The sheet material handling mechanism is an adsorption-type handling mechanism. The longitudinal conveyor belt and the sorting warehouse are located on the same side of the sheet material handling mechanism. The sheet material handling mechanism sends multiple adjacent sheets of the same order from the front of the longitudinal conveyor belt to the sorting warehouse for sorting.

8. The sheet metal sorting equipment according to claim 7, characterized in that: The longitudinal conveyor belt and the sorting warehouse are arranged side by side. The board handling mechanism vertically sends multiple identical order boards that are adjacent to each other from the front of the longitudinal conveyor belt into the sorting warehouse for sorting.

9. The sheet metal sorting equipment according to claim 1, characterized in that: A transverse conveyor mechanism is provided in front of the longitudinal conveyor belt. The transverse conveyor mechanism sends out multiple identical order boards conveyed by the longitudinal conveyor belt laterally, so that the multiple identical order boards are arranged side by side. The board handling mechanism picks up these multiple boards arranged side by side from the transverse conveyor mechanism and sends them to the sorting warehouse for sorting.

10. The sheet metal sorting equipment according to any one of claims 1 to 9, characterized in that: It is equipped with a conveyor belt drive mechanism that drives the longitudinal conveyor belt, and a controller that controls and connects the conveyor belt drive mechanism, the sheet material handling mechanism, and the sequencing mechanism.
