Description

Technical Field

[0001] This utility model relates to the field of stacking technology, and in particular to a stacking device. Background Technology

[0002] In the production process of plastic packaging boxes, the finished products need to be stacked into the boxes in an orderly and efficient manner for storage and transportation. Currently, there are several ways to achieve this process.

[0003] Traditional palletizing methods rely primarily on manual labor. Workers pick up plastic boxes transported from the conveyor belt one by one and place them into crates. This method is not only labor-intensive and inefficient, but the repetitive nature of the work can also lead to worker fatigue, increasing the risk of products slipping from their hands and making it difficult to maintain a stable production pace and palletizing quality. Furthermore, with the continuous rise in labor costs, this model also significantly increases production costs.

[0004] To overcome the drawbacks of manual operation, automation technology has been gradually introduced. Some equipment using robotic arms for grasping and palletizing has appeared on the market. However, such equipment is typically complex in structure, occupies a large area, and has high initial investment and maintenance costs, making it uneconomical for many small and medium-sized enterprises.

[0005] To address this, we propose a stacking device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stacking device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a stacking device, comprising two belt conveyors and an integrated industrial control computer, wherein an intermediate plate is fixedly connected to the outer surfaces of the two belt conveyors, and a synchronous drive assembly is installed on both belt conveyors.

[0008] Bearing seats are fixedly connected to adjacent sides of the outer surfaces of the two belt conveyors. A pneumatic rotating assembly is installed on both bearing seats. A dual-shaft cylinder is fixedly connected to the movable end of the pneumatic rotating assembly. A vacuum suction cup is fixedly connected to the movable end of the dual-shaft cylinder. A negative pressure assembly is installed on both the vacuum suction cup and the pneumatic rotating assembly.

[0009] A fixed frame is fixedly connected to the bottom of the vacuum suction cup, and a pneumatic lifting component is installed at the top of the fixed frame. The movable end of the pneumatic lifting component is fixedly connected to the packaging box positioning frame.

[0010] Furthermore, a diffuse reflection photoelectric sensor is fixedly connected to one side of the top of the belt conveyor. This sensor is used to detect the position of objects on the conveyor belt and realize automatic start / stop or positioning control.

[0011] Furthermore, the synchronous drive assembly includes a geared motor and a connecting shaft. The geared motor is fixedly connected to one side of the outer surface of the adjacent belt conveyor. The drive shaft of the geared motor passes through the adjacent belt conveyor and is fixedly connected to the main shaft of the adjacent belt conveyor. The two ends of the connecting shaft pass through the two belt conveyors respectively and are fixedly connected to the main shafts of the two belt conveyors. Through the linkage of the geared motor and the connecting shaft, the two belt conveyors are ensured to operate synchronously.

[0012] Furthermore, the pneumatic rotation assembly includes a rotary cylinder, which is fixedly connected to one side of the outer surface of a single bearing housing. The drive end of the rotary cylinder is fixedly connected to a mounting shaft, and the inner rings of the bearings built into the two bearing housings are fixedly sleeved on the outer surface of the mounting shaft. A dual-axis cylinder is fixedly connected to the top of the mounting shaft. The rotary cylinder drives the mounting shaft to rotate, thereby adjusting the direction of the vacuum suction cup, which facilitates the gripping and placement of objects and enables multi-angle operation.

[0013] Furthermore, the negative pressure assembly includes a vacuum pump, which is fixedly connected to the outer surface of the mounting shaft. A flexible hose is fixedly connected to the input end of the vacuum pump, and a three-way solenoid valve is fixedly connected to the top of the flexible hose. The three-way solenoid valve is fixedly connected to the bottom of the vacuum suction cup, and an air pipe is fixedly connected to the remaining port of the three-way solenoid valve. The vacuum pump controls the negative pressure of the vacuum suction cup through the flexible hose and the three-way solenoid valve to achieve reliable suction and rapid release of objects.

[0014] Furthermore, the pneumatic lifting assembly includes a single-axis cylinder, which is fixedly connected to the inner top of the fixed frame. The movable end of the single-axis cylinder passes through the fixed frame and is fixedly connected to a tray. The packaging box positioning frame is fixedly connected to the top of the tray. Two guide rods are symmetrically fixedly connected to the bottom of the tray, and the guide rods pass through the fixed frame and are slidably connected to the fixed frame. The single-axis cylinder drives the tray to rise and fall, and the guide rods work together to ensure smooth movement.

[0015] Furthermore, a support frame is fixedly connected to one side of the outer surface of each of the two belt conveyors, and the industrial control computer is fixedly connected to the outer surface of the support frame. The fixed frame is fixedly connected to the two support frames, and the support frame provides stable structural support.

It realizes full-process automation from conveying, accurate grasping, 180-degree flipping and stacking to adaptive descent of packaging boxes, which significantly improves production efficiency and stacking effect. At the same time, the compact structure effectively reduces equipment costs and product damage risks. Attached Figure Description

[0025] like Figures 1-3As shown, a stacking device is disclosed, comprising two belt conveyors 1 and an industrial control integrated computer 6.

Both ends of the connecting shaft 3 pass through the two belt conveyors 1 respectively and are fixedly connected to the main shafts of the two belt conveyors 1. When selecting belt conveyors 1, there is no need to match and install motors, thus facilitating the installation and use of the geared motor 4 and connecting shaft 3 in this application. The middle plate 2 not only serves as a structural connection but also enhances the overall rigidity and stability, preventing deformation or displacement after long-term operation. The connecting shaft 3 is made of 45# steel and undergoes heat treatment to enhance its torsional strength.

[0026] Two belt conveyors 1 are each fixedly connected to a bearing housing 16 on one adjacent side of their outer surfaces. The two bearing housings 16 are jointly equipped with a pneumatic rotating assembly. The movable end of the pneumatic rotating assembly is fixedly connected to a dual-axis cylinder 14. The pneumatic rotating assembly includes a rotating cylinder 17, which is fixedly connected to one side of the outer surface of a single bearing housing 16. The drive end of the rotating cylinder 17 is fixedly connected to a mounting shaft 13. The inner rings of the bearings built into the two bearing housings 16 are fixedly fitted onto the outer surface of the mounting shaft 13. The dual-axis cylinder 14 is fixedly connected to the top of the mounting shaft 13. The rotating cylinder 17 can be selected from the SMC CRB2 series, and the dual-axis cylinder 14 can be selected from the Airtac TCL series.

[0027] The movable end of the dual-axis cylinder 14 is fixedly connected to a vacuum suction cup 9. The vacuum suction cup 9 and the pneumatic rotation assembly are jointly equipped with a negative pressure assembly. The negative pressure assembly includes a vacuum pump 15, which is fixedly connected to the outer surface of the mounting shaft 13. The input end of the vacuum pump 15 is fixedly connected to a hose 21. The top of the hose 21 is fixedly connected to a three-way solenoid valve 19, which is fixedly connected to the bottom of the vacuum suction cup 9. The remaining port of the three-way solenoid valve 19 is fixedly connected to an air pipe 20. The vacuum pump 15 is a small electric vacuum pump, and the three-way solenoid valve 19 is a two-position three-way pilot-operated solenoid valve.

[0028] A fixed frame 7 is fixedly connected to the bottom of the vacuum suction cup 9. A pneumatic lifting assembly is installed at the top of the fixed frame 7. The movable end of the pneumatic lifting assembly is fixedly connected to the packaging box positioning frame 8. The pneumatic lifting assembly includes a single-axis cylinder 11, which is fixedly connected to the inner top of the fixed frame 7. The movable end of the single-axis cylinder 11 passes through the fixed frame 7 and is fixedly connected to a tray 12. The packaging box positioning frame 8 is fixedly connected to the top of the tray 12. Two guide rods 18 are symmetrically fixedly connected to the bottom of the tray 12. The guide rods 18 pass through the fixed frame 7 and are slidably connected to the fixed frame 7. The single-axis cylinder 11 is an SMC CXS series thin cylinder.

[0029] A diffuse reflection photoelectric sensor 10 is fixedly connected to one side of the top of the belt conveyor 1. The diffuse reflection photoelectric sensor 10 can be selected from Omron's E3Z series.

[0030] Each of the two belt conveyors 1 has a support frame 5 fixedly connected to one side of its outer surface, and the industrial control computer 6 is fixedly connected to the outer surface of the support frame 5, and the fixing frame 7 is fixedly connected to the two support frames 5.

[0031] The industrial control all-in-one computer 6 is electrically connected to the geared motor 4, diffuse reflection photoelectric sensor 10, single-axis cylinder 11, dual-axis cylinder 14, vacuum pump 15, rotary cylinder 17, and three-way solenoid valve 19, which facilitates the control of the overall operation.

[0032] Working principle: First, place the packaging box inside the packaging box positioning frame 8.

[0033] The completed plastic packaging boxes are fed from upstream equipment onto two synchronously operating belt conveyors 1. The geared motor 4 drives the main shafts of the two conveyors to rotate synchronously through the connecting shaft 3, ensuring smooth and straight transport of the packaging boxes and preventing deviation.

[0034] When the plastic packaging box reaches the predetermined position above the vacuum suction cup 9, the diffuse reflection photoelectric sensor 10, fixed to one side of the belt conveyor 1, detects the plastic packaging box and sends a signal to the industrial control computer 6. The industrial control computer 6 then controls the reduction motor 4 to stop running, so that the plastic packaging box stops at the gripping position.

[0035] After the plastic packaging box is positioned, the dual-axis cylinder 14 extends, pushing the vacuum suction cup 9 upward to adhere to the surface of the plastic packaging box. At the same time, the negative pressure component is activated. The vacuum pump 15 operates, generating negative pressure within the vacuum suction cup 9 through the hose 21 and the three-way solenoid valve 19, thereby firmly adhering the plastic packaging box.

[0036] Next, the pneumatic rotating assembly begins to operate. The rotating cylinder 17 drives the mounting shaft 13 to rotate within the bearing housing 16, thereby causing the dual-axis cylinder 14 and vacuum suction cup 9, which are fixed to the top of the mounting shaft 13, to rotate 180 degrees as a whole, so that the plastic packaging box is positioned directly above the packaging box.

[0037] Next, the dual-axis cylinder 14 extends and pushes the vacuum suction cup 9 down to send the plastic packaging box into the packaging box. At this time, the industrial control all-in-one computer 6 controls the three-way solenoid valve 19 to switch the passage, cut off the vacuum passage and connect the air pipe 20 to release air into the vacuum suction cup 9, eliminate the negative pressure, and make the plastic packaging box be placed stably in the packaging box.

[0038] When the pneumatic lifting assembly is activated, the movable end of the single-axis cylinder 11 extends downward, pushing the pallet 12 and the packaging box positioning frame 8 fixed thereon to descend, reducing the height of the packaging box and making room for the next plastic packaging box to be placed.

[0039] Then, the dual-axis cylinder 14 and the rotary cylinder 17 are reset in sequence, ready for the next work cycle.
