Description

Technical Field

[0001] This utility model relates to sheet material sorting equipment, specifically to sheet material sorting equipment with high sorting 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 bin, an outbound area, and a transport mechanism. The longitudinal conveyor belt sequentially transports multiple sheets to its front end. The transport mechanism, based on the order to which each sheet belongs, moves the sheets sequentially to the corresponding positions in the sorting bin, grouping sheets belonging to the same order together for sorting. Since the sheets may not be made of metal, a negative pressure transport mechanism with suction cups is more suitable. Traditional negative pressure suction cups can only process one sheet at a time, resulting in low sorting efficiency. To improve sorting efficiency, the negative pressure suction area of ​​the suction cups can be increased, designing them to pick up two or even three adjacent sheets from the longitudinal conveyor belt at once and transport them to the sorting bin for sorting. However, in this method, since the negative pressure needs to be distributed across multiple boards, the suction force of the negative pressure suction cup on each board is weakened. Also, since the longitudinal conveyor belt and the sorting bin are usually located on the left and right sides of the negative pressure handling mechanism, the negative pressure suction cup needs to rotate and move the boards picked up from the longitudinal conveyor belt to the sorting bin. During the entire rotation process, the boards will be subjected to centrifugal force and are prone to falling off the negative pressure suction cup. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a board sorting equipment with high sorting efficiency, in which the boards are not easy to fall off.

[0004] To solve the above-mentioned technical problems, the present invention provides a high-efficiency board sorting equipment, which is equipped with a longitudinal conveyor belt in the front and back direction. The longitudinal conveyor belt sends multiple boards from different orders forward to the front of the longitudinal conveyor belt. It is equipped with a sorting warehouse and a negative pressure conveying mechanism. The negative pressure conveying mechanism has several negative pressure adsorption parts. The several negative pressure adsorption parts pick up several adjacent boards from the front of the longitudinal conveyor belt and send them into the sorting warehouse for sorting. The longitudinal conveyor belt and the sorting warehouse are both located on the same side of the negative pressure conveying mechanism. The negative pressure conveying mechanism sends the boards picked up from the front of the longitudinal conveyor belt laterally into the sorting warehouse for sorting.

[0005] Furthermore, a negative pressure generator is provided to provide negative pressure for the negative pressure conveying mechanism. The several negative pressure adsorption parts of the negative pressure conveying mechanism are independent of each other and each has a negative pressure valve. When the negative pressure valve is opened, the corresponding negative pressure adsorption part is connected to the negative pressure generator to generate a negative pressure adsorption plate.

[0006] Furthermore, including the outbound area, the negative pressure handling mechanism delivers the pre-set boards from the sorting warehouse to the outbound area.

[0007] Furthermore, a transverse conveying mechanism is provided at the front of the longitudinal conveyor belt. The transverse conveying mechanism sends the plates that have been conveyed to the front of the longitudinal conveyor belt laterally out, so that several adjacent plates are arranged side by side. Several negative pressure adsorption parts of the negative pressure conveying mechanism are arranged side by side, and they lift these plates arranged side by side from the transverse conveying mechanism and send them into the sorting warehouse for sorting.

[0008] Furthermore, these horizontally arranged negative pressure adsorption parts form a row, while the negative pressure adsorption parts of the negative pressure conveying mechanism have multiple vertically arranged rows.

[0009] Furthermore, the longitudinal conveyor belt is specifically a roller conveyor belt, and the transverse conveying mechanism includes a transverse conveyor belt located between two adjacent rollers of the longitudinal conveyor belt.

[0010] Furthermore, a lifting mechanism is provided, which drives a transverse conveying mechanism to lift the sheet material that has been conveyed to the front of the longitudinal conveyor belt to leave the longitudinal conveyor belt. The transverse conveying mechanism then transversely delivers the sheet material that has been lifted to leave the longitudinal conveyor belt.

[0011] Furthermore, a lateral positioning element is provided to laterally block the sheet material conveyed by the lateral conveying mechanism, thereby laterally positioning it.

[0012] 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 several transverse positioning components to block several plates conveyed by the transverse conveying mechanism.

[0013] Furthermore, a conveyor belt drive mechanism is provided to drive the longitudinal conveyor belt, and a controller is provided to control the conveyor belt drive mechanism and the negative pressure conveying mechanism.

[0014] Because the negative pressure suction units of the negative pressure conveying mechanism can pick up several adjacent boards from the front of the longitudinal conveyor belt and send them into the sorting bin for sorting, the sorting efficiency is high. Since the longitudinal conveyor belt and the sorting bin are both located on the same side of the negative pressure conveying mechanism, the board conveying mechanism uses a lateral movement method to transport the boards. The boards are only subjected to lateral inertial forces during the acceleration and deceleration phases, and are not subjected to lateral inertial forces during the uniform motion phase. Therefore, compared with the prior art (where the boards are subjected to centrifugal force throughout the entire rotational movement process), this application can reduce the time the boards are subjected to force, thereby reducing the risk of the boards falling off, and the boards are less likely to fall off.

[0024] The present invention will be further described in detail below with reference to specific embodiments.

[0025] 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:

[0026] 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.

[0027] 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 left the warehouse conveyor belt 1, to the right side of the warehouse conveyor belt 1. At the same time, the right-side horizontal positioning mechanism 64 rises above the horizontal conveyor belt 61 and horizontally blocks the first board 91 that has been conveyed to the right side of the warehouse conveyor belt 1, thereby horizontally positioning the first board 91. After the horizontal conveyor belt 61 completes the conveying of the first board 91, the first vertical electric push rod 62 drives the horizontal conveyor belt 61 to descend and reset, so as to prevent the horizontal conveyor belt 61 from affecting the conveying of the second board 92 adjacent to the first board 91 by the warehouse conveyor belt 1. When the second sheet material 92 is conveyed to the front 11 of the inbound conveyor belt 1, the first vertical electric push rod 62 also drives the horizontal conveyor belt 61 to lift the sheet material 92. The 11 horizontal drive motors 601 also drive the 11 horizontal conveyor belts 61 to jointly convey the sheet material 92 laterally to the right side of the inbound 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.

[0028] 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 second board 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 second board 92, the transverse positioning column 643 of the left-hand transverse positioning mechanism 64 transversely blocks the board 92 transported by the transverse conveyor belt 61, thereby performing transverse positioning on the board 92. After completing the transverse positioning of the two boards 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 board transport mechanism 2 in transporting the board 9.

[0029] The sheet material handling mechanism 2 is a negative pressure handling mechanism, see Figure 5 The system includes a vertical module mounting frame 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 board sorting equipment 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 sections 250 arranged side-by-side. Each negative pressure adsorption section 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 for sorting. The specific control process is as follows:

[0030] 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 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 9With all negative pressure valves 255 closed, 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 one of the two boards 91 and 92 after horizontal positioning 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. Since the two negative pressure suction parts 251 and 252 of the board handling mechanism 2 can pick up two horizontally parallel boards 91 and 92 (these two boards 91 and 92 were originally adjacent to each other on the longitudinal conveyor belt 1) from the right side of the front 11 of the longitudinal conveyor belt 1 and send them into the sorting warehouse 3 for sorting, the sorting efficiency is high. In the prior art, the inbound conveyor belt 1 and sorting bin 3 are located on the left and right sides of the sheet material handling mechanism 2, respectively. The sheet material handling mechanism uses a rotating motion to transport the sheet material 9, and the sheet material 9 is subjected to centrifugal force throughout the process. In contrast, the sheet material sorting equipment of this application has both the inbound conveyor belt 1 and the sorting bin 3 located on the left side of the sheet material handling mechanism 2. The sheet material handling mechanism 2 uses a lateral movement to transport the sheet material 9. During the lateral movement, the sheet material 9 is only subjected to lateral inertial force during acceleration and deceleration, and is not subjected to lateral inertial force during uniform motion. Therefore, this application can reduce the stress time on the sheet material 9, thereby reducing the risk of the sheet material 9 falling off, making it less likely to fall.

[0031] In other embodiments, the rear of the inbound conveyor belt of the board sorting equipment is connected to the existing board processing equipment. The staff puts the boards to be processed onto the board processing equipment, and after processing the boards, the board processing equipment sends the boards to the rear of the inbound conveyor belt of the board sorting equipment, where the board sorting equipment sorts the processed boards. This will not be described in detail.

[0032] 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.
