Description

Technical Field

[0001] This utility model relates to the field of material transport equipment, specifically to a plate conveyor. Background Technology

[0002] Plate conveyors are used to transport stacked sheets of sheet metal one by one. Existing plate conveyor mechanisms include support roller sets, and suction cup distribution mechanisms and suction cup conveying mechanisms located on both sides above the support roller sets. The conveyor's workflow is as follows: First, multiple stacked sheets of sheet metal are placed on the support roller sets. Then, the suction cup distribution mechanism picks up the rear of the top sheet and rises, separating the rear of the sheet from the lower layers. Next, the suction cup conveying mechanism picks up the front of the sheet and conveys it forward to the next process. During this process, the suction cup distribution mechanism releases the rear of the sheet, and this cycle is repeated to achieve orderly sheet-by-sheet transport. However, in actual operation, when the suction cup distribution mechanism picks up the rear of the top sheet and rises, it is easy to accidentally pick up multiple sheets below it as well, which can adversely affect subsequent production. Utility Model Content

[0003] Based on this, and in view of the above-mentioned technical problems, the purpose of this utility model is to provide a plate conveyor.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A plate conveyor includes a frame, a support roller assembly mounted on the frame for carrying multiple stacked plates, and a transfer device located above the support roller assembly for conveying the plates. The transfer device includes a suction cup separating mechanism for first holding the rear of the plate to separate it from the next plate, and a suction cup conveying mechanism for holding the front of the plate and conveying it forward. It also includes a pressing mechanism located at the rear of the frame and cooperating with the suction cup separating mechanism to prevent multiple plates from being sucked up together.

[0006] Using the above technical solution, the pressing mechanism at the rear of the frame works in conjunction with the suction cup distribution mechanism. When the suction cup distribution mechanism picks up the rear part of the top layer of sheet material, the pressing mechanism simultaneously applies pressure to the rear edge of the sheet material to prevent multiple sheets from being picked up together, ensuring that only one sheet material is picked up at a time. Immediately afterwards, the suction cup conveying mechanism picks up the front part of the sheet material and conveys it forward; during this process, the suction cup distribution mechanism releases the rear part of the sheet material. This cycle repeats, thereby achieving the orderly conveying of sheets one by one.

[0007] In a specific embodiment of this utility model: the pressing mechanism includes a fixed rod fixed on the frame and located above the rear side of the support roller group, a pressing cylinder mounted on the fixed rod, and a pressing plate driven by the pressing cylinder to press down.

[0008] In a specific embodiment of this utility model: the pressure plate is an inclined plate. With this structure, the contact surface between the pressure plate and the sheet material is inclined. When the pressure plate descends under the drive of the downward-pressing cylinder and applies pressure to the rear edge of the sucked-up sheet material, the pressure plate and the rear edge of the sheet material are in line contact. Compared to surface contact, line contact effectively prevents the sheet material below the top layer from being sucked up along with it by applying pressure, and can press the edge of the second layer of sheet material below the top layer. It also reduces the constraint of the pressure plate on the rear of the top layer of sheet material, making it easier for the sheet material to separate from the sheet material below under the action of the suction cup separating mechanism.

[0009] In a specific embodiment of this utility model: the fixed rod is also provided with a rotatable baffle.

[0010] In a specific embodiment of this utility model: an air blowing mechanism is provided at the rear of the frame and near the sheet metal. The air blowing mechanism includes a high-pressure air nozzle connected to a high-pressure air source via an air pipe, and the high-pressure air nozzle faces the sheet metal.

[0011] In a specific embodiment of this utility model: the suction cup dispensing mechanism includes a first suction cup cylinder installed on both sides of the rear of the frame, and a first suction cup driven to rise and fall by the corresponding first suction cup cylinder.

[0012] In a specific embodiment of this utility model: the suction cup conveying mechanism includes a swing motor installed at the front of the frame, a longitudinally extending rotating shaft driven by the swing motor, second suction cup cylinders installed on both sides of the rotating shaft, and a second suction cup driven to rise and fall by the corresponding second suction cup cylinder.

[0013] In a specific embodiment of this utility model: a pressure roller is provided at the top of the frame between the suction cup dispensing mechanism and the suction cup conveying mechanism. With this structure, when the suction cup dispensing mechanism picks up the rear part of the uppermost sheet material, the pressure roller contacts and presses down on the sheet material to prevent the rear part of the sheet material from warping.

[0014] In a specific embodiment of this utility model: side plates are also provided on both sides of the support roller group on the frame. This structure can prevent the material plate from slipping off from both sides of the support roller group.

[0015] In summary, this invention utilizes a pressing mechanism and a suction cup dispensing mechanism in coordinated operation. When the suction cup dispensing mechanism picks up the rear part of the topmost sheet material, the pressing mechanism simultaneously applies pressure to the rear edge of the sheet material to prevent multiple sheets from being picked up together. Subsequently, the suction cup conveying mechanism picks up the front part of the sheet material and conveys it forward, thereby achieving orderly sheet material conveying one by one.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 and Figure 2 As shown, this utility model is a plate conveyor, including a frame 10, a support roller group 11 mounted on the frame 10 for carrying multiple stacked plates 9, and a transfer device for conveying the plates. In this embodiment, the plate 9 can be a thin aluminum plate or a thin stainless steel plate.

[0026] The transfer device includes a suction cup separating mechanism 21 for first holding the rear of the topmost sheet material so that the rear of the sheet material is separated from the next sheet material, and a suction cup conveying mechanism 22 for then holding the front of the sheet material and conveying it forward.

[0027] In addition, it also includes a pressing mechanism 30 located at the rear end of the frame 10 and cooperating with the suction cup dispensing mechanism 21, which is used to prevent multiple sheets of board 9 from being sucked up together.

[0028] In this way, the pressing mechanism at the rear of the frame works in conjunction with the suction cup distribution mechanism. When the suction cup distribution mechanism picks up the rear part of the top layer of sheet material, the pressing mechanism simultaneously applies pressure to the rear edge of the sheet material to prevent multiple sheets from being picked up together, ensuring that only one sheet material is picked up at a time. Immediately afterwards, the suction cup conveying mechanism picks up the front part of the sheet material and conveys it forward; during this process, the suction cup distribution mechanism releases the rear part of the sheet material. This cycle is repeated to achieve orderly sheet material conveying. Furthermore, a lifting plate is installed below the sheet material stack between adjacent support rollers of the support roller group, and a lifting mechanism is connected below the lifting plate. The lifting mechanism drives the lifting plate to raise the sheet material stack, ensuring that the top layer of sheet material is always at a suitable working height. Here, the lifting mechanism can be driven by a motor, hydraulically, or pneumatically.

[0029] In this embodiment, the suction cup dispensing mechanism 21 includes a first suction cup cylinder 211 installed on both sides of the rear of the frame 10, and a first suction cup 212 driven to rise and fall by the corresponding first suction cup cylinder 211.

[0030] In this embodiment, the suction cup conveying mechanism 22 includes a swing motor 221 installed at the front of the frame, a longitudinally extending rotating shaft 222 driven by the swing motor 221, second suction cup cylinders 223 installed on both sides of the rotating shaft 222, and a second suction cup 224 driven to rise and fall by the corresponding second suction cup cylinder 223.

[0031] In this embodiment, the pressing mechanism 30 includes a fixed rod 31 fixed on the frame 10 above the rear side of the support roller group 11, a pressing cylinder 32 mounted on the fixed rod, and a pressing plate 33 driven by the pressing cylinder 32 to press down.

[0032] Among them, the pressure plate 33 is an inclined plate. Thus, the contact surface between the pressure plate and the sheet material is inclined. When the pressure plate descends under the drive of the downward pressure cylinder and applies pressure to the rear edge of the sucked-up sheet material, the pressure plate and the rear edge of the sheet material are in line contact. Compared to surface contact, line contact effectively prevents the sheet material below the top layer from being sucked up along with it by applying pressure, and can press the edge of the second layer of sheet material below the top layer. It also reduces the constraint of the pressure plate on the rear of the top layer of sheet material, making it easier for the sheet material to separate from the sheet material below under the action of the suction cup separating mechanism.

[0033] In this embodiment, a pressure roller 23 is provided at the top of the frame 10 between the suction cup dispensing mechanism 21 and the suction cup conveying mechanism 22. With this structure, when the suction cup dispensing mechanism picks up the rear part of the uppermost sheet material, the pressure roller contacts the sheet material and presses it down to prevent the rear part of the sheet material from lifting up.

[0034] In this embodiment, a rotatable baffle 12 is also provided on the fixing rod 31. This structure can prevent the sheet metal from slipping off the rear side of the frame.

[0035] In this embodiment, side plates 13 are also provided on both sides of the support roller group 11 on the frame 10. This structure can prevent the material plate from slipping off the sides of the support roller group.

[0036] In this embodiment, an air blowing mechanism 40 is provided behind the frame 10 and near the sheet metal. This air blowing mechanism 40 includes a high-pressure nozzle 42 connected to a high-pressure air source via an air pipe 41. The high-pressure nozzle 42 faces the sheet metal 9. With this structure, high-pressure gas is injected through the high-pressure nozzle into the gaps between the sheet metal layers, using the impact force of the airflow to break the adhesion between the sheets, further preventing the suction cup from picking up multiple sheets along with the sheet metal.

[0037] Combination Figures 3-7 As shown, the above describes a plate conveyor of this utility model. During operation, firstly, multiple stacked plates 9 are placed on a pallet 8. A forklift can then lift the pallet 8 and plates 9 and place them on the support roller assembly 11. Subsequently, two first suction cup cylinders 211 are activated, driving two first suction cups 212 to descend and lift the rear of the topmost plate 9. Then, the two first suction cup cylinders 211 drive the two first suction cups 212 to rise, causing the rear of the plate 9 to rise and separate it from the next plate. During this process, a pressing cylinder 32 is activated, driving a pressure plate 33 to descend and apply pressure to the rear edge of the plate, preventing the next plate below from being lifted along with it, thus ensuring that only one plate is lifted at a time. High-pressure air nozzles at the rear inject airflow to assist in separating the plates. Immediately afterwards, the two second suction cups 224 are activated, driving them to pick up the front part of the sheet material. The two second suction cup cylinders 224 then drive the two second suction cups 224 upwards, lifting the front part of the sheet material 9. Simultaneously, the two first suction cups 212 release the rear part of the sheet material 9, and the pressure plate is driven back to its initial position. Then, the swing motor 221 is activated, driving the rotating shaft 222 to rotate, causing the two second suction cups 224 to swing forward, moving the front part of the sheet material 9 forward and upward. During this process, the two second suction cups 224 release the front part of the sheet material, which is then conveyed forward to the next process under inertia. The second suction cups 224 are then driven back to their initial state to await the next sheet material. Through this cyclical operation, the sheets are conveyed sequentially and orderly.

[0038] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
