Description

Technical Field

[0001] The invention relates to the technical field of stacking devices, and in particular to a stacking device for aluminum plates. Background Art

[0002] The palletizer automatically stacks cartons that have been loaded into containers on pallets and pallets in a certain arrangement. It can stack multiple layers and then push them out to facilitate forklift transportation to the warehouse for storage. It realizes intelligent operation and management, is simple and easy to master, and can greatly reduce labor and labor intensity. The aluminum plate palletizing device works together through mechanical, electrical and control systems. The aluminum plate may be relatively thin and large in area, and the surface is easily scratched. Therefore, the aluminum plate is grabbed from the production line or conveyor belt and stacked into stacks according to preset modes such as stacking and staggered.

[0003] A linear stacking device is disclosed in a Chinese patent with announcement number CN110817460B, including a guide rail mechanism, a first swing arm mechanism, a second swing arm mechanism and a third swing arm mechanism; the first swing arm mechanism is arranged at the output end of the guide rail mechanism, the second swing arm mechanism is arranged at the output end of the first swing arm mechanism, the third swing arm mechanism is arranged at the output end of the second swing arm mechanism, the third swing arm mechanism is provided with a synchronization component to synchronize transmission with the first swing arm mechanism and the second swing arm mechanism, and the third swing arm mechanism always maintains a horizontal state. In this device, no matter how the first swing arm mechanism and the second swing arm mechanism swing, the third swing arm can always remain horizontal; the first swing arm mechanism, the second swing arm mechanism and the third swing arm mechanism can be folded into a "4" shape for storage, which can greatly reduce the space occupied by the entire device. This device can be freely spliced ​​and can be operated on multiple common rails and freely dispatched. It only needs to be hung on the side of the processing equipment to operate freely.

[0004] The above patent document is able to work on a common track by free and unlimited splicing. However, the stacking device generally stacks the plate by sucking the four corners of the plate through suction cups. However, when stacking thin aluminum plates, the thin aluminum plates are light and thin, and the rigidity may be insufficient. When the four corners are sucked by suction cups, the middle part may sag due to its own weight due to lack of support. The sagging will cause the plates to be unable to be accurately aligned during stacking, affecting the neatness of the stacking, and may even cause displacement or collapse, resulting in the need for four-corner positioning after the aluminum plates are stacked. However, the four-corner positioning after stacking is likely to cause friction between the contact surfaces of the two aluminum plates, affecting the production quality of the aluminum plates.

DETAILED DESCRIPTION

[0032] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1 to 12 As shown, an aluminum plate stacking device of the present invention comprises: a gantry and a sliding frame 20, the sliding frame 20 is slidably arranged on the gantry along the length direction, and also comprises: a correction component, a stretching component, a suction cup 40, a roller conveying platform 80, a top extension component and a placement platform 90, the correction component is lifted and arranged at the bottom of the sliding frame 20, the correction component can synchronously approach the two opposite side walls of the thin aluminum plate, the stretching component is slidably arranged below the correction component so that the stretching component can slide laterally along the correction component, and a A suction cup 40 is provided, which is used for negative pressure suction on the four corners of the upper surface of the aluminum plate, and the stretching component can stretch the thin aluminum plate in four corner directions. The roller conveyor platform 80 and the placement platform 90 are arranged side by side under the gantry. The roller conveyor platform 80 is used to convey the trimmed thin aluminum plate to the bottom of the gantry, and the placement platform 90 is used to place the stacked thin aluminum plates. The top extension component is arranged on the roller conveyor platform 80, and the top extension component can fill the gap between the rollers to ensure the adsorption effect of the suction cup on the thin aluminum plate.

[0034] When stacking thin aluminum plates, the thin aluminum plates are cut and transported to the bottom of the gantry through the roller conveyor 80, and then the extension component pushes upward to fill the gaps between the multiple rollers, so as to ensure that the suction cup 40 is better fitted with the top surface of the thin aluminum plate during negative pressure suction, avoiding the uneven fit of the suction cup 40 and the thin aluminum plate or the appearance of gaps due to insufficient support at the bottom of the thin aluminum plate. After the suction cup 40 absorbs the plate in the air, the stretching component pushes the suction cup 40 to move in four corner directions respectively, so as to stretch the thin aluminum plate. The top surfaces of the plates are at the same horizontal height, and then the correction assembly approaches the two opposite sides of the thin aluminum plate. When the plate deviates, the stretching assembly will slide under the correction assembly. When the correction assemblies touch the two opposite side walls of the plate, the correction is completed. Finally, the sliding frame 20 slides along the gantry, and then the thin aluminum plate is moved from above the roller conveyor table 80 to above the placement table 90, so as to achieve precise stacking, avoid sagging in the middle due to the dead weight when stacking the thin aluminum plates, improve the stacking accuracy, and avoid mutual friction when adjusting the position of the thin aluminum plates after stacking, thereby ensuring the production quality of the products.

[0035] It should be noted that even if a suction cup is added in the middle position of the existing palletizing device, a slight wave shape will still appear, which affects the accuracy of palletizing. At the same time, it is easy to cause the aluminum plate to fall off during the movement, causing damage to the aluminum plate. At the same time, the rigidity of the aluminum plate needs to be ensured when correcting and positioning the aluminum plate in the air.

[0036] like Figure 1 As shown, the gantry includes: a U-shaped bracket 10, a support frame 11 and a cross bar 12, the opening of the U-shaped bracket 10 faces downward, and the two end surfaces of the U-shaped bracket 10 are fixedly connected to the ground, the support frame 11 is arranged on the right side of the U-shaped bracket 10, and the top surface of the support frame 11 and the U-shaped bracket 10 are at the same horizontal height, the cross bar 12 is arranged on the top of the support frame 11 and the U-shaped bracket 10, and the support frame 11 and the U-shaped bracket 10 are respectively located near the two ends of the cross bar 12, the support frame 11 and the U-shaped bracket 10 are used to support the cross bar 12, the sliding frame 20 is slidably arranged on the cross bar 12, and the sliding frame 20 can slide along the length direction of the cross bar 12, and a driving assembly is arranged on the cross bar 12, and the driving assembly is used to drive the sliding frame 20 to slide along the length direction of the cross bar 12, so that the plate moves from above the roller conveyor table 80 to above the placement table 90.

[0037] like Figures 1 to 4As shown, the correction component includes: a correction frame 30, a dual-axis motor 32, a guide rod 34 and a positioning telescopic rod 36. A top extension rod 21 is arranged at the bottom of the sliding frame 20, and the top extension rod 21 has four. The correction frame 30 is fixedly assembled at the bottom end of the top extension rod 21, so that the top extension rod 21 pushes the correction frame 30 up and down, and then the thin aluminum plate is raised or lowered. The dual-axis motor 32 is arranged at the middle position of the top of the correction frame 30. It should be noted that in this embodiment, the shafts at both ends of the dual-axis motor 32 belong to the same rotor so that the two ends rotate synchronously. The output ends of the dual-axis motor 32 are both provided with screws 33, and the threads on the screws 33 are in opposite directions. A supporting fixed block 31 is arranged on the top of the correction frame 30, and the supporting fixed blocks 31 are symmetrically distributed on both sides of the dual-axis motor 32. At the same time, the two supporting fixed blocks 31 are arranged on the axis of the screw 33. The screw 33 rotates through the supporting fixed block 31, so that the supporting fixed block 31 supports the screw 33 to ensure the stability of the rotation of the screw 33.

[0038] A moving block 35 is provided on the outer circumference of the two screw rods 33, and the two moving blocks 35 can move closer to or away from each other. A guide rod 34 is provided on two side walls away from the two supporting and fixing blocks 31, and each supporting and fixing block 31 has two guide rods 34, and the guide rod 34 runs through the moving block 35 to ensure the stability of the movement of the moving block 35. A positioning telescopic rod 36 is provided at the bottom of each moving block 35, and the lower end of the positioning telescopic rod 36 is a positioning rod. A positioning plane 37 is provided on the outer circumference of the positioning rod, and the positioning planes 37 on the two positioning telescopic rods 36 are arranged relatively. It should be noted that pressure sensors are provided on the two positioning planes 37 so that the two pressure sensors can contact the side wall of the plate at the same time. When pressure information is generated, it indicates that the positioning correction is completed. At the same time, a controller is provided on the correction frame 30, and the controller is used to receive the pressure sensor signal and control the operation of the dual-axis motor 32.

[0039] When the aluminum plate is transported to the roller conveyor table 80 after cutting, an angle deviation will occur. Therefore, it is necessary to use a correction component to correct it to improve the accuracy of stacking. The double-axis motor 32 drives the screw rod 33 to rotate. The rotation of the screw rod 33 drives the two moving blocks 35 to move back to back. The movement of the moving block 35 drives the two positioning telescopic rods 36 to move away from each other, so that the positioning telescopic rods 36 are located on both sides of the thin aluminum plate. The positioning telescopic rods 36 move downward and extend so that the positioning planes 37 on the positioning telescopic rods 36 are located on the same horizontal plane of the thin aluminum plate. The double-axis motor 32 drives the moving block 35 and the positioning telescopic rod 36 to move relative to each other. The stretching assembly is slidably arranged below the correction assembly, and the plate moves so that the stretching assembly slides below the correction assembly until both pressure sensors are pressured and positioning is completed. This enables the aluminum plate to be positioned and adjusted in the air, thereby improving the accuracy of stacking and avoiding friction damage when adjusting the aluminum plate after stacking.

[0040] It should be noted that during this positioning process, it is necessary to ensure that the top surface of the thin aluminum plate is flat to avoid pushing and deforming the aluminum plate during correction positioning, thereby ensuring positioning accuracy. Therefore, the stretching assembly can stretch the thin aluminum plate while ensuring positioning accuracy.

[0041] like Figures 5 to 8 As shown, the stretching assembly includes: a fixed plate 50, a guide plate 52, a guide groove 53, a stretching sleeve 54, a translation block 63 and a motor 61. The fixed plate 50 is arranged directly below the correction frame 30. The top surface of the fixed plate 50 is provided with a motor 51. The guide plate 52 is rotatably arranged at the bottom of the fixed plate 50, and the output end of the motor 51 is transmission-connected with the top of the guide plate 52. The guide plate 52 is in the shape of a four-pointed star, and the four corners on the guide plate 52 are arranged along the circumferential direction at ninety degrees, and each corner has a A guide groove 53 is provided, and the guide grooves 53 on the symmetrical angles are on the same straight line. A fixed guide block 56 is provided at the bottom of the fixed plate 50, and there are four fixed guide blocks 56. The stretching sleeve 54 is slidably set on the fixed guide block 56, and the stretching sleeve 54 corresponds to the fixed guide block 56 one by one, and a sliding groove 57 is provided below the fixed guide block 56, and a sliding strip 58 is provided on the opposite side wall of the stretching sleeve 54, so that the stretching sleeve 54 can slide and cooperate with the fixed guide block 56.

[0042] A guide rod 2 55 is fixedly provided on the top of one end of the stretching sleeve 54 close to the guide groove 1 53, and the guide rod 2 55 is located inside the guide groove 1 53, so that the rotation of the guide plate 52 can drive the stretching sleeve 54 to slide in the fixed guide block 56, and the suction cup 1 40 is movably arranged at the bottom of the stretching sleeve 54, and the suction cup 1 40 corresponds to the stretching sleeve 54 one by one, and the suction cup 1 40 and the stretching sleeve 54 are vertically arranged. It should be noted that each suction cup 1 40 is connected to a pipeline and finally connected to the negative pressure suction device.

[0043] When the aluminum plate is stretched, multiple suction cups 40 respectively perform negative pressure suction on the four corners of the plate to adsorb the plate, and then the motor 51 drives the guide plate 52 to rotate. The rotation of the guide plate 52 makes the guide groove 53 and the guide rod 55 slide together, so that the guide plate 52 rotates to push the guide rod 55 to drive the stretching sleeve 54 to move toward the four corners, so that the suction cup 40 moves toward the four corners, so as to stretch the thin aluminum plate, so that the entire thin aluminum plate is in a taut state, ensuring the accuracy of correction positioning and the accuracy of stacking.

[0044] like Figures 5 to 8 As shown, the second support frame 59 is fixedly arranged at the bottom of the fixed plate 50, and a second suction cup 60 is arranged at the bottom of the second support frame 59, and the second suction cup 60 is located in the middle position, so that the plate can be sucked as a whole when the plate is sucked, and the four support legs of the second support frame 59 are respectively located between two adjacent corners of the guide plate 52 as shown in FIG. Figure 6 As shown, the support frame 2 59 does not interfere with the guide plate 52.

[0045] In order to enable the stacking device to adapt to plates of different sizes, the suction cup 40 can be adjusted at the same time, thereby improving the applicable scenarios of the device and ensuring the accuracy of stacking.

[0046] like Figure 6 As shown, each stretching sleeve 54 is provided with a groove along the length direction, and the groove opening faces downward, a lead screw 62 is arranged in the groove along the length direction, and a motor 61 is installed at one end of each stretching sleeve 54, the output end of the motor 61 is connected to the lead screw 62, and a translation block 63 is arranged on the outer peripheral surface of the lead screw 62, and a suction cup 40 is arranged at the bottom of the translation block 63, so that when it is necessary to stack plates of different sizes, it is necessary to adjust the suction cup 40 in time, so that the motor 61 drives the lead screw 62 to rotate, the rotation of the lead screw 62 drives the translation block 63 to move, and the movement of the translation block 63 drives the suction cup 40 to move, so that the suction cup 40 can be away from or close to the guide plate 52, so that the suction cup 40 can be quickly adjusted, and plates of different sizes can be automatically adjusted to reduce the manual workload.

[0047] like Figures 8 to 9As shown, in order to ensure that the stretching assembly and the plate can slide under the correction assembly when the plate is corrected, the stretching assembly and the correction assembly are connected by setting a sliding assembly, which includes: a slide bar 70, an elastic member 72 and a support bar 71. The bottom end of the slide bar 70 is fixedly set on the top of the fixed plate 50, and the slide bar 70 is T-shaped as a whole. A T-shaped slide groove 74 is opened at the bottom of the correction frame 30 along the length direction, and the top end of the slide bar 70 is slidably matched with the T-shaped slide groove 74, so that the correction assembly can correct the aluminum plate. When positioning and adjusting, the slide bar 70 can slide in the T-shaped slide groove 74. The support rod 71 is arranged at both ends of the T-shaped slide groove 74, and the outer peripheral surface of the support rod 71 is provided with an elastic member 72, and the two ends of the elastic member 72 are respectively connected to the slide bar 70 and the side wall of the T-shaped slide groove 74. The elastic member 72 is used to reset the slide bar 70. A bottom plate 73 is provided at the bottom of the correction frame 30, and the bottom plate 73 is located below the elastic member 72, so as to support the elastic member 72 and prevent the elastic member 72 from detaching from the T-shaped slide groove 74.

[0048] When the positioning telescopic rod 36 pushes the plate to position, the slide bar 70 on the top of the stretching assembly slides inside the T-shaped slide groove 74, and the elastic member 72 is driven to expand and contract according to the sliding direction of the slide bar 70. When the plate stacking is completed, the elastic member 72 can reset the slide bar 70 to keep it in the initial position. It should be noted that a ball bearing can be installed inside the T-shaped slide groove 74 to ensure the sliding cooperation effect of the entire slide bar 70 and the T-shaped slide groove 74.

[0049] like Figure 10 to Figure 11 As shown, the driving assembly includes: a second motor 26 and a threaded rod 24, the second motor 26 is arranged on the side wall of one end of the cross bar 12, a plurality of guide grooves are provided on the top of the cross bar 12, and the plurality of guide grooves are arranged along the width direction of the cross bar 12, the threaded rod 24 is arranged in the middle guide groove along the length direction of the cross bar 12, and the threaded rod 24 is transmission-connected with the second motor 26, a guide block 22 is arranged on the bottom wall of the sliding frame 20, and the guide block 22 is threadedly matched with the threaded rod 24, a guide bar 23 is arranged at the bottom of the sliding frame 20, and the guide bar 23 is symmetrically arranged on the left and right sides of the sliding frame 20, and the guide bar 23 is slidably matched with the guide grooves on both sides.

[0050] When stacking the plates, it is necessary to move the plates from above the roller conveyor platform 80 to the placement platform 90, and the motor 26 drives the threaded rod 24 to rotate, and the rotation of the threaded rod 24 drives the guide block 22 to move along the length direction of the cross bar 12, and at the same time the guide bar 23 slides inside the guide groove, so that the sliding frame 20 can drive the stable movement of the plates.

[0051] like Fig.12As shown, the extension assembly includes: a telescopic rod 81, a support plate 84, an extension frame 82 and an extension plate 83. A plurality of rollers are arranged on the roller conveyor platform 80, and there are gaps between the rollers. The support plate 84 is arranged on the roller conveyor platform 80, the telescopic rod 81 is arranged on the top of the support plate 84, and the extension frame 82 is arranged on the top of the telescopic rod 81. A plurality of extension plates 83 are arranged on the top of the extension frame 82, and the arrangement direction of the extension plates 83 is consistent with the arrangement direction of the rollers, and each extension plate 83 corresponds to a gap between adjacent rollers.

[0052] When the aluminum plate reaches above the roller conveyor platform 80, the telescopic rod 81 pushes the extension frame 82 to move upward, and the extension frame 82 moves upward to drive the extension plate 83 to move, so that the gap between the multiple extension plates 83 is aligned with the roller, so that the extension plate 83 stops against the lower surface of the aluminum plate, ensuring that the suction cup 40 and the suction cup 60 are more stable when negatively sucking the aluminum plate, thereby improving the stacking accuracy.

[0053] like Fig.12 As shown, the placement table 90 is a lifting table, which can be raised and lowered according to the height of the stacking, and the lifting placement table 90 is a prior art, which will not be described in detail here.
