Description

Technical Field

[0001] This invention relates to the field of packaging machinery technology, specifically to an automated packaging and stacking production line for rubber-sealed product boxes. Background Technology

[0002] Rubber rings are indispensable sealing elements in the industrial field, and their packaging and transportation requirements directly affect product quality and performance. Proper packaging and transportation not only protect the rings from physical damage but also prevent chemical corrosion, ensuring they maintain optimal performance upon arrival. Currently, for small or precision rubber rings, individual packaging is recommended, meaning each ring is packaged independently to reduce friction and collision, protecting the integrity of the sealing surface. For large-sized or large quantities of the same specifications, batch packaging can be used. Multiple rings are neatly arranged, secured with plastic straps or ropes, and then placed in an outer box. However, it is important to ensure sufficient cushioning space between the rings during batch packaging to prevent deformation during transportation. For specially shaped or easily deformable rings, such as O-rings and V-rings, custom-made packaging boxes or molds should be used for fixation to ensure they maintain their original shape during transportation.

[0003] However, most existing packaging box packing operations use semi-automated or manual assistance methods: 1. Packaging process: Mostly stand-alone packing machines are used. Manual labor is required to move the packaging boxes to the packing station, complete the single box bundling, and then manually transfer and stack them. 2. Conveying process: Mostly ordinary roller conveyor lines are used, which only have basic conveying functions and lack centering, positioning, and connecting buffer structures; 3. Stacking process: It relies heavily on manual stacking or simple lifting equipment, resulting in low stacking efficiency, poor positioning accuracy, and easy damage to packaging boxes and stacking tilt.

[0004] 4. Existing production lines are mostly decentralized single-machine combinations, with no coordinated control system between the equipment. A large amount of manual intervention is required to connect the processes, making it impossible to achieve fully automated continuous operation.

[0005] 5. Packaging, conveying, and stacking processes all require manual coordination, resulting in high labor costs, low work efficiency, and limited single-shift capacity. 6. The lack of a centering and positioning structure during the conveying process leads to large deviations in the packaging position, making it prone to tilting and collapse during stacking, resulting in a high packaging loss rate. 7. Each machine operates independently without linkage control, which can easily lead to problems such as workstation blockage and idling, resulting in low production line utilization. 8. Each box of rubber products weighs tens of kilograms (ranging from 30 to 40 kilograms) after packaging, and the number of stacking layers varies from 4 to 7 (with a height of about 1.5 meters). The packaging process involves multiple manual operations, and there is a high risk of workplace injury during handling and stacking, which does not meet the requirements for safe production. 9. Existing equipment is mostly designed for single-size packaging boxes and cannot accommodate the packaging needs of boxes of different sizes and weights. It has weak flexible production capabilities. Therefore, there is an urgent need for an automated packaging and stacking production line for rubber-sealed product packaging boxes to solve the above-mentioned technical problems. Summary of the Invention

[0020] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention. It should also be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings. In the embodiments of the present invention, the different types of cross-sectional lines are not labeled according to national standards, nor do they specify material requirements for the components; they are used to distinguish the cross-sectional views of the components.

[0021] Please see Figure 1-7 An automated packaging and stacking production line for rubber-sealed product boxes includes a hoist 1, a pusher 2, a receiving platform 3, a pushing and centering platform 4, a packing machine 5, a conveyor 6, and a stacker 7 connected in sequence. The hoist 1 and pusher 2 form a hoist frame assembly unit, which includes a vertical frame 8, a hoisting drive mechanism 9, a pushing mechanism 10, load-bearing forks 11, and guide columns 12. The receiving platform 3 consists of a roller conveyor frame 13 and a receiving platform 14. The packing machine 5... The stacker crane 7 consists of a main frame 15, a strapping head 16, a conveyor roller 17, a positioning block 18, and a control system 19. The conveyor table 6 consists of a frame 20, power rollers 21 and 22, and a transmission chain 23. The stacker crane 7 consists of a lifting column 24, a chain drive system 25, a gripping frame 26, and a gripping pallet 27. The chain drive system 25 is installed on the lifting column 24, and the gripping frame 26 is installed on one side of the chain drive system 25. The gripping pallet 27 is installed on the gripping frame 26.

[0022] The vertical frame 8 is equipped with a lifting drive mechanism 9 on one side, a pushing mechanism 10 on one side, a bearing fork 11 on one side, and a guide column 12 on one side of the bearing fork 11 to receive the packaging box. The lifting drive mechanism 9 drives the bearing fork 11 to rise and fall vertically along the guide column 12, raising the packaging box to the height of the receiving platform 3. The pushing mechanism then smoothly pushes the packaging box onto the receiving platform 3.

[0023] One side of the roller conveyor frame 13 is equipped with a receiving platform 14 to receive the packaging boxes conveyed by the elevator. The packaging boxes are automatically pushed to complete the centering and positioning through the roller conveyor frame and the pushing centering mechanism, so as to ensure the positional accuracy of subsequent packaging and stacking and avoid stacking skew.

[0024] The frame 20 is equipped with a power roller 21, and a drive motor 22 is installed at one end of the power roller 21. A transmission chain 23 is installed on the output shaft of the drive motor 22 via a sprocket. The packing machine 5 receives the packaging boxes conveyed by the previous process and automatically completes the binding operation through the binding head. After binding, it is automatically released to the conveyor table 6. It can adapt to the adjustment requirements of different binding numbers and binding force. The conveyor table 6 receives the packaged items output by the packing machine 5 and realizes continuous conveying through the conveyor belt to ensure smooth conveying and avoid the packaging boxes from slipping or shifting.

[0025] The lifting column 24 is equipped with a chain drive system 25, and a gripping frame 26 is installed on one side of the chain drive system 25. A gripping pallet 27 is installed on the gripping frame 26. The stacker 7 receives the packaging boxes conveyed by the lifting frame, and completes the gripping of the packaging boxes through the gripping mechanism. The lifting column 24 adjusts the stacking height and finally accurately stacks the packaging boxes onto the pallet, realizing multi-layer automatic stacking, which can adapt to the needs of different stacking layers and stacking methods.

[0026] The control system 19 uses a PLC as the main controller, is equipped with a touch screen, and is equipped with position sensors, photoelectric sensors, and limit switches to realize real-time detection of the status of each workstation.

[0027] The working principle and usage process of this invention are as follows: First, parameters such as the size of different packaging boxes and the number of packing layers are set in the control system 19. During use, the box number and stacking layers are selected in advance on the touchscreen. The lifting machine 1 determines the lifting distance based on the input box number, and is executed by the lifting motor and encoder, with a control accuracy between 3 and 5 millimeters. The centering machine is controlled by the receiving platform 3 and the pushing centering platform 4, with a control accuracy between 10 and 15 millimeters. When the receiving platform 3 receives a material signal, it descends to the designated position, determined by the input box number. This is then executed by two cylinders on the pushing centering platform 4. Corresponding sensors are installed on the cylinders, and the sensor positions match the box size.

[0028] After the carton is aligned, the receiving platform 3 lowers so that the carton is at the same height as the conveyor platform 6. Upon receiving a signal, the conveyor platform 6 sends the carton to the worktable of the packing machine 5. The packing machine 5 is equipped with two sensors at the front and rear, which execute the packaging instructions at the front and rear respectively. The packed carton is then sent by the conveyor platform 6 to the stacker crane robot arm, where it is stacked sequentially according to the set number of layers. Finally, the stacker crane 7 achieves automatic stacking.

[0029] The elevator 1, pusher 2, receiving platform 3, pusher centering platform 4, packing machine 5, conveyor 6, and stacker 7 achieve coordinated operation through signal interaction. The completion of the preceding station triggers the start of the following station, ensuring continuous and efficient operation of the production line. All equipment in the entire packaging production line are coordinated and linked through the control system, requiring no manual intervention and operating in full automation. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
