[0058] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0059] The following is combined with Figures 1 to 5 The sheet metal conveying system of the present invention is described.

[0060] Combination Figures 1 to 3 The sheet metal conveying system of the present invention includes a first vertical storage unit 100, a first transfer device 200, and a detection device 300. The first vertical storage unit 100 is provided with a plurality of first storage positions 150; the first transfer device 200 is used to: send sheet metal stacks 600 from the entrance side of the first vertical storage unit 100 into the first storage positions 150, or to remove sheet metal stacks 600 from the first storage positions 150; the detection device 300 is provided on the entrance side of the first vertical storage unit 100 and is used to collect the specification information of the sheet metal stacks 600 sent into the first storage positions 150, the specification information being used to provide data support for the outgoing of the sheet metal stacks 600.

[0061] In this embodiment, when storing the board stacks 600 through the first vertical storage 100, each first storage position 150 is suitable for storing board stacks 600 of the same specification. Different first storage positions 150 can store board stacks 600 of the same or different specifications. The three-dimensional arrangement of multiple first storage positions 150 can change the original form of stacking board stacks 600 of different specifications in different locations on the site, so that board stacks 600 of different specifications can be arranged vertically and do not directly press against each other. On the one hand, it can ensure that the board stacks 600 of the required specifications are not affected by other board stacks 600 when they are taken out of the warehouse. On the other hand, it can avoid wasting space.

[0062] Combination Figure 2 In some embodiments of the present invention, the first vertical storage unit 100 includes a support frame 110, a circulation drive mechanism 120, and a support member 130.

[0063] The support frame 110 includes a first frame and a second frame arranged along a first horizontal direction X. The first frame and the second frame can be a vertical support structure formed by combining rod structures. The first frame and the second frame are respectively provided with annular slide rails, which are located on the adjacent sides of the first frame and the second frame and are arranged vertically. The gap formed between the first frame and the second frame can serve as the installation position for the support member 130.

[0064] All support members 130 are horizontally arranged, with their length direction along a first direction and their width direction along a second direction Y, where the second direction is a horizontal direction perpendicular to the first direction. One end of each support member 130 is slidably connected to an annular slide rail of the first frame, and the other end is slidably connected to an annular slide rail of the second frame, thereby allowing multiple support members 130 to slide along an annular track. Multiple support members 130 are provided, and the multiple support members 130 are evenly arranged circumferentially along the annular slide rails. The upper side of each support member 130 forms a first storage position 150, on which the stack of plates 600 can be placed and supported.

[0065] In this embodiment, the support member 130 can be, for example, plate-shaped or box-shaped. Both ends of the support member 130 can be directly slidably connected to the annular slide rail, or they can be slidably connected to the annular slide rail via a structure such as a hanging rod; no specific limitation is made here. Furthermore, both ends of the support member 130 serve as the inlet and outlet of the plate stack 600. When the support member 130 adopts a box structure, one end of the support member 130 forms a first opening, which serves as the inlet of the plate stack 600, and the other end forms a second opening, which serves as the outlet of the plate stack 600.

[0066] Optionally, the support frame 110 also includes a guide rail, which is arranged parallel to the annular rail and along the second direction. The corresponding ends of the support member 130 and the annular rail and the guide rail are slidably connected to the annular rail through a connecting node and to the guide rail through another connecting node. This ensures that the support surface of the support member 130 is always on its upper side and that the force on the support member 130 is balanced.

[0067] The cyclic drive mechanism 120 is adapted to drive each of the first storage positions 150 to alternately move to the bottom of the first vertical storage unit 100, so as to facilitate the entry and exit of the board stack 600 at the bottom of the first vertical storage unit 100. Specifically, it can drive the empty support 130 to move to the bottom to perform the board stack 600 storage operation, or move the support 130 containing the board stack 600 to the top to reserve space for the board stack 600 in the empty support 130 to be stored. This design can reduce the hoisting height of the board stack 600 when it is stored and improve safety.

[0068] Optionally, each of the multiple first storage positions 150 is provided with a board trolley 140, which is used to carry the board stack 600. The shape of the board trolley 140 is adapted to the shape of the support member 130, and the board trolley 140 can slide into the support member 130. The first entry and exit drive mechanism 240 is adapted to drive the board trolley 140 to enter and exit the first storage position 150. When the board trolley 140 slides into the support member 130 under the drive of the first entry and exit drive mechanism 240, the board stack 600 can be stored in the first vertical warehouse 100. When the board trolley 140 slides out of the support member 130 under the drive of the first entry and exit drive mechanism 240, the board stack 600 in the first vertical warehouse 100 can be unloaded.

[0069] It is worth noting that the above embodiments are only illustrative descriptions of the structure of the first vertical storage 100. Other circulating vertical storage structures in the prior art that can realize the function of the first vertical storage 100 in the embodiments of the present invention should also be within the protection scope of the present invention.

[0070] See you later Figure 1 In some embodiments of the present invention, the first transfer device 200 includes a first infeed drive mechanism 240, which is used to: send the stack of boards 600 into the first storage position 150 located at the bottom of the first vertical warehouse 100, or to move the stack of boards 600 out of the first storage position 150 located at the bottom of the first vertical warehouse 100.

[0071] Optionally, the first entry / exit drive mechanism 240 includes a first movable slide rail, a second movable slide rail, a first push-pull assembly, and a second push-pull assembly. The first and second movable slide rails are disposed on the supporting ground and arranged along a first direction. The first movable slide rail is disposed on the entrance side of the first storage unit 100, and the second movable slide rail is disposed on the exit side of the first storage unit 100. The rollers of the sheet metal trolley 140 are adapted to roll in cooperation with the first and second movable slide rails. The first push-pull assembly is adapted to drive the sheet metal trolley 140 to slide along the first movable slide rail into the support member 130 located at the bottom of the first storage unit 100. The second push-pull assembly is adapted to drive the sheet metal trolley 140 to slide along the second movable slide rail out of the support member 130 located at the bottom of the first storage unit 100.

[0072] Optionally, the first push-pull assembly includes a first drive motor, a first lead screw and nut transmission structure, and a first clamp. The first drive motor is connected to the lead screw in the first lead screw and nut transmission structure, and the first clamp is disposed on the nut connected to the first lead screw and nut transmission structure. The first clamp can be an electric clamp or a hydraulic clamp, etc., and the first clamp is suitable for clamping the plate trolley 140.

[0073] Optionally, the second push-pull assembly includes a second drive motor, a second lead screw and nut transmission structure, and a second clamp. The second drive motor is connected to the lead screw in the second lead screw and nut transmission structure, and the second clamp is disposed on the nut connected to the second lead screw and nut transmission structure. The second clamp can be an electric clamp or a hydraulic clamp, etc., and the second clamp is suitable for clamping the plate trolley 140.

[0074] In some embodiments of the present invention, the first transfer device 200 further includes a sheet material conveying line 210, a sheet material stacking mechanism 220, and a first transfer mechanism 230.

[0075] The inlet of the sheet material conveyor line 210 can be connected to the product production line. After the product is produced, products of the same specification enter the sheet material conveyor line 210 in the form of stacks. The end of the sheet material conveyor line 210 is connected to the sheet material stacking mechanism 220.

[0076] The sheet metal stacking mechanism 220 and the sheet metal conveyor line 210 can be connected by a structure such as a conveyor belt or hoisting equipment to transfer sheet metal stacks 600 from the sheet metal conveyor line 210 to the sheet metal stacking mechanism 220. The sheet metal stacking mechanism 220 can be a frame structure used for temporary storage of sheet metal stacks 600, thereby realizing the stacking operation of sheet metal stacks 600. For example, when the sheet metal stack 600 conveyed by the sheet metal conveyor line 210 is short, two sheet metal stacks 600 can be arranged along the length of the sheet metal stack 600 at the sheet metal stacking mechanism 220, so that two sheet metal stacks 600 of the same specification can be stored simultaneously in the same first storage position 150.

[0077] The first transfer mechanism 230 is used to transfer the stack of plates 600 from the plate stacking mechanism 220 to the entrance side of the first vertical warehouse 100. In this embodiment, the first transfer mechanism 230 can be a conveyor belt, a robotic arm, or a hoisting device, etc. Preferably, the first transfer mechanism 230 in this embodiment adopts a hoisting device.

[0078] According to an embodiment of the present invention, in the sheet material conveying system, the detection device 300 is disposed on the bottom entrance side of the first vertical storage 100, and is adapted to collect the specification information of the sheet material stack 600 when it is stored in the first vertical storage 100.

[0079] Combination Figure 3 In some embodiments, the detection device 300 includes a side detection unit 310 and a length detection unit 320. The side detection unit 310 is used to collect side profile information of the stack of boards 600. The length detection unit 320 is used to detect the length value of the boards.

[0080] Optionally, the side detection unit 310 includes a laser profile sensor, which is adapted to face the side wall of the stack of plates 600 when the stack of plates 600 is fed into the first vertical storage 100, so as to collect the side profile information of the stack of plates 600.

[0081] Optionally, two side detection units 310 are provided. The two side detection units 310 respectively collect the contour information of both sides of the board stack 600, so that when the board stack 600 contains two stacks of boards side by side, the side contour information of the two stacks of boards in the board stack 600 can be collected respectively.

[0082] In some embodiments of the present invention, the detection device 300 further includes a support 330, which may be a portal frame structure. The support 330 is provided with a passageway, and the first transfer device 200 is adapted to drive the stack of plates 600 through the passageway. The side detection unit 310 is connected to the support 330 and is located on both sides of the passageway. The length detection unit 320 is connected to the support 330 and is located on the upper side of the passageway.

[0083] Combination Figure 4 and Figure 5 In some embodiments of the present invention, the length detection unit 320 includes an elastic support structure, a pressure roller 321, and an encoder 322. The pressure roller 321 is disposed at the movable end of the elastic support structure and is adapted to roll into contact with the stack of boards 600 as it passes by. The encoder 322 is connected to the pressure roller 321 and is used to detect the number of rotations of the pressure roller 321. It should be noted that the stack of boards 600 slides along its length direction as it passes by. The pressure roller 321 begins to roll into contact with the stack of boards 600 when it arrives and rolls on the outer wall of the stack of boards 600 as it moves, stopping rolling when the stack of boards 600 leaves. The encoder 322 collects the number of rotations of the pressure roller 321 as it rolls, and the length of the stack of boards 600 can be determined by the number of rotations collected by the encoder 322.

[0084] In some embodiments of the present invention, the elastic support structure includes a guide rod 323, a limiting nut 324, a compression spring 325, and a wheel seat 326. The guide rod 323 slidably passes through the upper rod of the bracket 330. The portion of the guide rod 323 above the upper rod is threadedly connected to the limiting nut 324. The lower end of the guide rod 323 is fixedly connected to the wheel seat 326. The compression spring 325 is sleeved on the guide rod 323, with its upper end abutting against the upper rod and its lower end abutting against the wheel seat 326. A pressure roller 321 is rotatably mounted on the wheel seat 326, and an encoder 322 is mounted on the wheel seat 326 and connected to the axle of the pressure roller 321.

[0085] It should be noted that the above embodiments are merely illustrative descriptions of the side detection unit 310 and the length detection unit 320. Other structures of the side detection unit 310 and the length detection unit 320 should also be within the scope of protection of this invention.

[0086] For example, the length detection unit 320 includes a vision sensor on the upper or both sides of the passageway, which acquires image information of the upper side of the stack of boards 600 passing through the passageway and performs length processing on the image information to obtain the length value of the board.

[0087] For example, the length detection unit 320 includes a laser rangefinder on the upper or both sides of the passageway, which obtains the length information of the stack of boards 600 by performing laser scanning on the stack of boards 600.

[0088] For example, the side detection unit 310 includes ultrasonic detectors disposed on both sides of the passageway. When the stack of plates 600 passes by, the ultrasonic detectors can collect the side profile information of the stack of plates 600 by detecting the reflected signal of the stack of plates 600.

[0089] In some embodiments of the present invention, the sheet material conveying system further includes a control device, which is electrically connected to the detection device 300.

[0090] Optionally, the control device includes a calculation unit electrically connected to the side detection unit 310. The calculation unit is used to determine the thickness value of the sheet material based on the side profile information. Specifically, the calculation unit is used to determine the number of sheet materials based on the number of high points in the side profile information, and to determine the thickness of the sheet materials based on the number of sheet materials and the height of the sheet material stack 600 in the side profile information. The number of high points refers to the number of protruding ridges on the side wall of the sheet material stack 600, with one protruding ridge on one side of each sheet material.

[0091] For example, when the number of high points N in the side profile of the stack of boards 600 is 3 and the height L of the stack of boards 600 is 600mm, then the thickness of the board is L / N = 600mm / 3 = 200mm.

[0092] In some embodiments of the present invention, the control device is also electrically connected to the first vertical storage unit 100, and the control device is also used to establish board storage information based on specification information and the identifier of the first storage location 150.

[0093] Optionally, the identifier of the first storage location 150 can be the number of the first storage location 150, and the board storage information includes the correspondence between the identifier of the first storage location 150 and the specification information of the stored board stack 600.

[0094] Optionally, the control device is also electrically connected to the first transfer device 200. The control device is also used to determine the required first storage location 150 based on the specification information and board storage information in the outbound information, and to control the first transfer device 200 to remove the board stack 600 from the required first storage location 150.

[0095] In some embodiments of the present invention, the sheet material conveying system further includes a second vertical storage unit 500 and a second transfer device 400. The second vertical storage unit 500 is provided with a plurality of second storage positions; the second transfer device 400 is disposed between the first vertical storage unit 100 and the second vertical storage unit 500, and is used to send the sheet material stacks 600 removed from the first vertical storage unit 100 into the second storage positions, and to remove the sheet material stacks 600 in the second storage positions from the second vertical storage unit 500.

[0096] Optionally, the second vertical storage unit 500 has the same structure as the first vertical storage unit 100.

[0097] Optionally, the second transfer device 400 includes a second transfer mechanism and a second infeed / outfeed drive mechanism. The second infeed / outfeed drive mechanism is disposed at the bottom of the second vertical storage unit 500 and is used to: deliver the stack of boards 600 into a second storage position located at the bottom of the second vertical storage unit 500, or to remove the stack of boards 600 located in the second storage position at the bottom of the second vertical storage unit 500. The second transfer mechanism may employ a hoisting device and is adapted to move the stack of boards 600 removed from the first vertical storage unit 100 to the second infeed / outfeed drive mechanism.

[0098] Optionally, the second entry / exit drive mechanism has the same structure as the first entry / exit drive mechanism 240.

[0099] In some embodiments of the present invention, the control device is also electrically connected to the second vertical storage 500 and the second transfer device 400. The control device is also used to control the operation of the second vertical storage 500 and the second transfer device 400 when the first transfer device 200 removes the stack of boards 600 from the desired first storage position 150, so as to send the stack of boards 600 removed from the first vertical storage 100 into the second storage position.

[0100] Optionally, the control device is also used to control the second transfer device 400 to move the stack of boards 600 in the second storage position out of the second vertical warehouse 500 when a signal of arrival of the transport vehicle 700 is received.

[0101] In this embodiment, the second vertical storage unit 500 can serve as a buffer, thereby pre-storing the required specifications of the board stacks 600 into the second vertical storage unit 500 before the transport vehicle 700 arrives, thus shortening the screening time of the board stacks 600.

[0102] The following is combined with Figure 6 The control method of the sheet material conveying system provided by the present invention is described below. The control method described below can be referred to in correspondence with the sheet material conveying system described above.

[0103] The control methods for the sheet metal conveying system include:

[0104] S100, control the first transfer device 200 to send the stack of plates 600 into the first storage position 150.

[0105] Specifically, the control device controls the operation of the first vertical warehouse 100 based on the storage situation in the first vertical warehouse 100, circulates the first storage position 150 where no stack of board material 600 is stored to the bottom of the first vertical warehouse 100, and controls the operation of the first transfer device 200 to send the stack of board material 600 into the first storage position 150 where no stack of board material 600 is stored at the bottom of the first vertical warehouse 100.

[0110] In some embodiments of the present invention, the control method for the plate conveying system further includes:
