Description

Technical Field

[0001] The invention belongs to the technical field of aerated building block transportation, and in particular relates to an environment-friendly aerated building block stacker. Background Art

[0002] Aerated blocks are a lightweight, porous new building material made of cement, lime, gypsum and other raw materials through processes such as gasification, pouring, static stopping, cutting, and steaming. They have excellent properties such as thermal insulation, sound insulation, and fire prevention, and are widely used in the construction field. In the production and transportation of aerated blocks, stacking and transportation are key links, which directly affect production efficiency and product quality.

[0003] Most of the existing aerated block stacking and conveying equipment are operated manually or semi-automatically. Manual stacking is not only labor-intensive, but also has low stacking efficiency, which is difficult to meet the needs of large-scale production. Although semi-automatic equipment has improved efficiency to a certain extent, it still has deficiencies in flexibility and automation. For example, when grabbing and placing aerated blocks, existing equipment can only operate in fixed directions and positions, and cannot adapt to the different directions of aerated blocks during the conveying process, resulting in a less smooth stacking process.

[0004] In addition, when packing the palletized aerated blocks, manual intervention is usually required to manually wrap the packaging film around the aerated blocks. This not only increases labor costs, but also poses safety hazards and affects the continuity and automation level of the production line. Summary of the invention

[0050] The positioning roller 572 on the film-laying assembly 57 is made of steel roller shaft, with a length of 600mm and a diameter of 50mm. The surface is treated with rust prevention, which is suitable for LLDPE stretch film with a width of 500mm and a thickness of 25μm. It has good tensile properties and self-adhesiveness, ensuring that the packaging film is not easy to break during the winding process and can be firmly adhered to the surface of the aerated block. The sliding frame 571 is made of high-strength aluminum alloy material, which is light in weight and has good fatigue resistance, ensuring stability during high-speed packaging; the top plate 573 is made of steel plate material with a thickness of 5mm, providing sufficient support to avoid deformation during rotation; the support bar 5731 is made of carbon fiber composite material, which has high strength and low weight, further enhancing the structural stability of the film-laying assembly 57.

[0051] In order to verify the packaging efficiency of the wrapping mechanism, a comparative experiment was conducted. The experiment was conducted at a constant temperature of 25°C and a relative humidity of 50%. The same model and specification of aerated blocks (the stacking height of each pallet does not exceed 2000mm) were used, and each group of experiments was repeated 6 times. The same type of packaging film (LLDPE stretch film, thickness 25μm) was used for both manual packaging and packaging by this equipment to ensure the fairness and comparability of the experiment. During the experiment, the rotation speed of the turntable 52, the height adjustment speed of the film assembly 57, and the tension of the packaging film were controlled to eliminate the interference of other variables and ensure the reliability of the data and the validity of the experimental results. The results are shown in Table 3 below.

[0052] Table 3: Comparative experimental data of packaging efficiency of winding mechanism

[0053] It can be seen from the data in Table 3 that the packaging time of this equipment is reduced by about 66% compared with manual packaging, which significantly improves the packaging efficiency; During the experiment, the time of manual packaging fluctuated greatly, averaging 8.5 minutes, while the packaging time of this equipment was stable at 3 minutes, showing the efficiency and consistency of the equipment in the automated packaging process. In addition, during the packaging process, the equipment accurately adjusts the height of the film assembly 57 through the electric telescopic rod 58 to ensure that the packaging film is evenly wrapped around the outside of the aerated block, further improving the packaging quality. In terms of formula, the tension of the wrapping film can be calculated by the following formula to ensure the uniformity and adhesion of the film: F = σ × A Where F is the force applied to the packaging film (N), σ is the tension of the packaging film (N / m²), and A is the contact area (m²).

[0054] Through the above design and experimental verification, the winding mechanism 5 in this embodiment effectively solves the problem of manually winding the packaging film in the prior art, reduces labor costs, eliminates safety hazards, and improves the continuity and automation level of the production line.

[0055] Embodiment 5:

[0056] In this embodiment, the placement table 4 includes a roller 42, which is made of a seamless steel pipe with an outer diameter of 60 mm, a wall thickness of 3 mm, and a surface galvanized for rust prevention; the roller 42 is connected to a first drive motor 44 through a chain, and the first drive motor 44 adopts an AC reduction motor, model SEW R series, power 1.5 kW, reduction ratio 1:30, and output speed of about 47 rpm. The structural design of the placement table 4 ensures the stability and positioning accuracy of the pallet during the transportation process.

[0057] To verify the conveying efficiency of the placement table, a pallet conveying experiment was conducted. The experiment was conducted at a constant temperature of 25°C and a relative humidity of 50%. The same specifications of pallets (length 1200mm, width 800mm, thickness 150mm) were used, and each group of experiments was repeated 6 times. Both the traditional manual conveying and the automatic conveying of this equipment were tested under the same operating conditions to ensure the fairness and comparability of the experiment. The results are shown in Table 4 below.

[0058] Table 4: Pallet conveying efficiency experimental data

[0059] The experimental results show that the pallet conveying time of this equipment under the same experimental conditions is significantly lower than that of manual conveying. The average conveying time is shortened from 4.5 minutes to 1 minute, and the conveying efficiency is improved by about 77%. During the experiment, the pallet specifications, conveyor belt speed and environmental conditions were controlled, and the interference of other variables was eliminated to ensure the reliability of the data and the validity of the experimental results. This shows that the placement table design of this equipment can efficiently and stably complete the pallet conveying task, significantly improve production efficiency and reduce production costs.

[0060] Embodiment 6:

[0061] This embodiment integrates the above-mentioned mechanisms to construct a set of fully automatic aerated block stacking and conveying system. The system integrates the support 1, the moving mechanism 2, the grabbing mechanism 3, the placement table 4 and the winding mechanism 5, and realizes the full process automation operation from the conveying, grabbing, stacking, packaging to the pallet conveying of the aerated blocks.

[0062] In order to evaluate the overall performance of this system, a one-week production test was conducted and the results are shown in Table 5 below.

[0063] Table 5: System production performance comparison data

[0064] From the data in the table, we can see that the average daily production of this system has increased by 50%, the labor cost has decreased by 62.5%, and the equipment failure rate has decreased by 80%. Although the energy consumption per unit product has increased slightly, the overall production cost has been significantly reduced due to the improvement in production efficiency.

[0065] This embodiment effectively solves the problems of poor equipment flexibility, low degree of automation, and need for manual intervention in the prior art, realizes fully automatic stacking and packaging of aerated blocks, and improves the overall efficiency and automation level of the production line.

[0066] The working principle of the present invention is as follows: when in use, the aerated blocks to be stacked are transported to the interior of the support 1 by the conveyor belt 6, and the pallet is placed on the placement table 4; The grabbing mechanism 3 is controlled to move in the three-dimensional space inside the bracket 1 by means of the X-axis slide 22, the Y-axis slide 23 and the Z-axis guide column 24, and the clamping plate 33 is driven by the cylinder 32 to clamp the aerated building blocks transported on the conveyor belt 6 and place them on the tray on the placement table 4; Since the gripping mechanism 3 and the Z-axis guide column 24 can rotate, the gripping mechanism 3 can clamp the aerated blocks in different directions on the conveyor belt 6; When the pallet placed on the placement table 4 is fully stacked, the second drive motor 55 drives the turntable 52 to rotate, thereby driving the placement table 4 to rotate. Before the placement table 4 rotates, one end of the packaging film placed on the positioning roller 572 is wound around the stacked aerated blocks. In this way, during the rotation of the placement table 4, the packaging film can be wound around the aerated blocks, and the height of the film placing assembly 57 can be adjusted by the electric telescopic rod 58, so that the aerated blocks on the pallet can be completely wound. After packaging is completed, the first driving motor 44 drives the roller 42 to rotate, so that the packaged tray placed on the roller 42 can be transported to the next process.

[0067] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
