Description

Technical Field

[0001] This utility model belongs to the field of automation equipment technology, specifically relating to a push mechanism for a stacker crane. Background Technology

[0002] In modern production and automated warehousing systems, stacker cranes, as important automated equipment, are widely used in the conveying, stacking, and handling of various products. Existing stacker cranes typically use fixed-position push plates to move materials. However, traditional pushing methods often suffer from problems such as difficulty in adjusting the pushing angle, insufficient pushing force, and an unstable pushing process, resulting in low production efficiency and easy damage to materials, failing to meet the demands for efficient and precise pushing.

[0003] In existing technologies, although some pushing mechanisms use drive mechanisms for pushing control, most structures have the following problems: First, they are not flexible enough when adjusting the pushing angle and pushing force, and require complex mechanical devices; second, the control of actuators such as cylinders is not precise enough, resulting in low adhesion between the push plate and the material, causing unstable pushing; third, there is significant friction and incoordination in the cooperation between the drive mechanism and the pushing mechanism, which affects the operating efficiency of the equipment. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a pushing mechanism for a stacker crane, which can effectively control the pushing angle, improve pushing accuracy, and ensure material stability during the pushing process.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A stacker crane pushing mechanism includes a support platform, a track symmetrically arranged on the upper end of the support platform, a first slide table slidably connected on the track, and a first driving mechanism arranged on one side of the support platform for driving the first slide table to move on the track.

[0007] A pushing mechanism is slidably connected to the top of the first slide, and a second driving mechanism is provided on one side of the first slide. The second driving mechanism is used to drive the pushing mechanism to move on the first slide.

[0008] The pushing mechanism includes a second slide that is slidably connected to the first slide. A cylinder and a deflector plate are rotatably connected to the upper end face of the second slide. The telescopic end of the cylinder is rotatably connected to the deflector plate, and a push plate is connected to one end of the deflector plate.

[0009] Furthermore, the push plate is shaped like a convex character, and both ends of the push plate are connected to protective heads.

[0010] Furthermore, the protective head is designed to be arc-shaped.

[0011] Furthermore, the upper end of the support platform is symmetrically connected to a sleeper plate, and the track is installed on the sleeper plate.

[0012] Furthermore, the first drive mechanism includes a first motor mounted on the lower end face of the support platform, a first pulley mounted on one side, and a first belt connecting the output end of the first motor and the first pulley;

[0013] One end of the first slide is clamped onto the first belt;

[0014] The first motor drives the first belt to rotate, which in turn drives the first slide connected to the first belt to slide on the track.

[0015] Furthermore, the second drive mechanism includes a second motor installed at the bottom of the first slide, a second pulley installed on one side of the first slide, and a second belt installed between the output end of the second motor and the second pulley;

[0016] One side of the driving mechanism is connected to the second belt;

[0017] The second motor drives the second belt to rotate, which in turn drives the push mechanism connected to the second belt to slide on the first slide.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Firstly, the combined design of the first and second drive mechanisms allows the pushing mechanism to slide smoothly on the track. This dual-drive approach effectively avoids the problems of unstable pushing and unbalanced movement inherent in traditional single-drive methods. The first drive mechanism moves the first slide table along the track, ensuring the pushing mechanism accurately reaches the position of the material to be pushed; the second drive mechanism controls the sliding of the pushing mechanism on the first slide table, allowing the pusher plate to smoothly contact and push the material. Compared to traditional solutions, this design significantly improves the equipment's operating efficiency and precision.

[0020] Secondly, the pushing mechanism employs a combination of cylinders and a deflector plate, enabling precise control of the pusher plate's elevation angle. The cylinder's extension and retraction directly affects the pusher plate's angle, resulting in a tighter fit between the pusher plate and the material, thus improving the stability and reliability of the pushing effect. Traditional pushing mechanisms often suffer from unstable material pushing due to inflexible pusher plate angle adjustments. This invention solves this problem through precise cylinder control, ensuring accurate angle adjustments during each pushing process and preventing unnecessary damage to the material.

[0021] Furthermore, the push plate is designed in a U-shape with protective heads at both ends, further enhancing the protection of materials during the pushing process. The protective heads feature an arc design, reducing the impact force when the push plate contacts the material, thus better ensuring the stability of the material during pushing. This design not only effectively reduces the risk of material breakage but also improves the smoothness of the pushing process, ensuring efficient material handling.

[0022] Finally, key components such as the support platform, tracks, and drive unit are all made of high-strength, wear-resistant materials, thereby improving the durability and reliability of the entire system. The high quality of these components ensures the stability of the equipment during long-term operation, preventing performance degradation due to wear or aging, and extending the service life and working efficiency of the stacker crane.

[0036] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0037] Example 1:

[0038] See Figure 1-4 A stacker crane push mechanism includes a support platform 1, a track 12 symmetrically arranged on the upper end of the support platform 1, a first slide 2 slidably connected on the track 12, and a first drive mechanism 3 arranged on one side of the support platform 1, the first drive mechanism 3 being used to drive the first slide 2 to move on the track 12.

[0039] The top of the first slide 2 is slidably connected to a pushing mechanism 4, and a second driving mechanism 5 is provided on one side of the first slide 2. The second driving mechanism 5 is used to drive the pushing mechanism 4 to move on the first slide 2.

[0040] The pushing mechanism 4 includes a second slide 41 slidably connected to the first slide 2. The upper end face of the second slide 41 is rotatably connected to a cylinder 42 and a deflector plate 43. The telescopic end of the cylinder 42 is rotatably connected to the deflector plate 43, and one end of the deflector plate 43 is connected to a push plate 44.

[0041] Specifically, the support platform 1 is made of high-strength steel to ensure sufficient load-bearing capacity during long-term use. The track 12 is made of wear-resistant alloy material, which has high durability and corrosion resistance, ensuring smooth operation of the first slide 2 when sliding on it and reducing friction and wear.

[0042] See Figure 3 The push plate 44 is shaped like a convex character, and both ends of the push plate 44 are connected to protective heads 441. The protective heads 441 are made of rubber and polymer composite materials, which have good elasticity and cushioning, effectively preventing damage to the items being pushed during the pushing process. The push plate 44 itself is made of high-strength aluminum alloy, which has strong load-bearing capacity and lightweight characteristics, making it suitable for long-term, high-frequency operation.

[0043] See Figure 3 The protective head 441 is designed in an arc shape, which fully considers the protection of the item during the pushing process. The arc design helps the push plate 44 to make smoother contact with the item to be pushed, reducing contact impact and improving the smoothness and stability of the push.

[0044] See Figure 1The upper end face of the support platform 1 is symmetrically connected to the sleeper plate 11, and the track 12 is installed on the sleeper plate 11. The sleeper plate 11 is made of steel and has been surface treated to improve its wear resistance and enhance the stability of the track 12, ensuring that the track 12 can stably support the sliding movement of the first slide table 2 and the pushing mechanism 4.

[0045] See Figure 1-2 The first drive mechanism 3 includes a first motor 31 mounted on the lower end face of the support platform 1 and a first pulley 33 mounted on one side. A first belt 32 is connected between the output end of the first motor 31 and the first pulley 33. The first motor 31 drives the first belt 32 to rotate, thereby driving the first slide table 2 connected to the first belt 32 to slide on the track 12. The first motor 31 is a three-phase asynchronous motor of model "Y2-90L2-4", which has high efficiency and stability and can provide continuous and reliable power. The first belt 32 is made of polyurethane material, which has high strength and wear resistance, and can ensure smooth transmission during long-term operation.

[0046] One end of the first slide 2 is clamped onto the first belt 32, and a special clamping device is used to ensure a firm connection during transmission, preventing the slide from falling off or becoming unstable. The surface of the slide 2 is finely treated to reduce friction and ensure smooth sliding on the track 12.

[0047] See Figure 1-3 The second drive mechanism 5 includes a second motor 51 mounted on the bottom of the first slide 2 and a second pulley 53 mounted on one side of the first slide 2. A second belt 52 is installed between the output end of the second motor 51 and the second pulley 53. The second motor 51 is a high-efficiency servo motor of model "YZD-200L2-4", which has good response speed and precise control capability, and can accurately regulate the movement of the drive mechanism 4 on the first slide 2. The second belt 52 is made of wear-resistant polyurethane material, which can withstand large tensile and frictional forces, ensuring stable performance even after long-term operation.

[0048] The second motor 51 drives the second belt 52 to rotate, which in turn drives the push mechanism 4 connected to the second belt 52 to slide on the first slide table 2. The sliding design of the push mechanism 4 adopts a high-precision linear guide rail, which can ensure that its sliding on the first slide table 2 is more stable, reduce the loss caused by friction, and improve the overall operating accuracy.

[0049] Example 2: Achieving Precise Pushing with a Dual-Drive System for the Propulsion Mechanism

[0050] This embodiment optimizes the pushing accuracy and stability of the stacker crane by employing a combined design of a first drive mechanism and a second drive mechanism. The first drive mechanism uses a three-phase asynchronous motor of model "Y2-90L2-4" with a power of 1.5kW. The first belt 32, which is matched with it, is made of wear-resistant polyurethane material to ensure that there will be no excessive wear or slippage during transmission. The first slide table 2 slides on the track 12 via the first belt 32, achieving high positioning accuracy and stable pushing.

[0051] The second drive mechanism uses a servo motor of model "YZD-200L2-4" with a power of 2.2kW, and drives the push mechanism 4 to slide precisely via the second belt 52. The advantage of this drive system is that by precisely controlling the speed and direction of the second motor, the push plate 44 can be accurately docked with the material to be pushed, avoiding deviations and uneven sliding during the pushing process.

[0052] Comparative Cases:

[0053] Compared to traditional stacker cranes with a single drive system, the single drive mode often results in low pushing accuracy, especially when the material is heavy, the pusher plate may not be able to advance stably. Compared to traditional technology, this embodiment adopts a dual drive system, which allows the pushing mechanism to be precisely controlled in multiple directions, thus providing better stability and efficiency during pushing, especially in the material handling process.

[0054] Example 3: Adjusting the push plate angle by coordinating the cylinder and the steering plate

[0055] In this embodiment, the pushing mechanism adopts a design that combines a cylinder 42 and a deflector plate 43. The extension and retraction of the cylinder adjusts the elevation angle of the push plate 44, making its contact with the material closer. The cylinder 42 is an electric cylinder of model "SMCCY1B63-250", which has strong thrust and can withstand loads up to 500N, ensuring that the push plate angle can still be accurately adjusted under high loads.

[0056] The deflector plate 43 is connected by a rotating shaft structure, which allows the deflector plate to form the optimal angle with the pusher plate during the extension and retraction of the cylinder, adapting to the pushing requirements of different materials. The pusher plate 44 is made of high-strength aluminum alloy, which has excellent pressure resistance and lightweight characteristics, ensuring stability and durability during the pushing process.

[0057] Comparative Cases:

[0058] Traditional pushing mechanisms typically employ a fixed-angle pusher plate design, which cannot flexibly adjust the angle according to the shape of the material or the pushing situation, resulting in inaccurate material docking or unstable pushing. In contrast, this embodiment adjusts the pusher plate angle through the cooperation of a cylinder and a deflector plate, enabling the optimal pushing angle for each push, effectively improving the accuracy and stability during the pushing process, especially when pushing fragile materials.

[0059] Example 4: The convex design of the push plate and the application of the protective head

[0060] In this embodiment, the push plate 44 adopts a convex shape and has protective heads 441 at both ends, which are arc-shaped. The protective heads 441 are made of high-molecular composite materials, which have excellent elasticity and wear resistance, and can effectively prevent impact damage to materials during the pushing process. The push plate 44 is made of high-strength aluminum alloy, which has good compressive strength, and is lightweight and easy to operate, making it suitable for use in high-frequency production environments.

[0061] The curved design of the protective head 441 reduces the impact of contact with materials, improving the stability of materials during the pushing process. This is especially effective in reducing material damage caused by pushing when handling fragile materials or materials with special surface requirements.

[0062] Comparative Cases:

[0063] Traditional pusher designs typically employ right angles or flat surfaces. These designs can easily generate significant impact forces upon contact with materials, potentially causing surface damage or breakage, especially with fragile materials. In contrast, the convex pusher and curved protective head design of this embodiment better cushions impact forces during the pushing process, ensuring material integrity and making it particularly suitable for handling precision and fragile materials.

[0064] Example 5: Use of high-strength steel and high-wear-resistant alloy materials

[0065] In this embodiment, key components such as the support platform 1, track 12, and push plate 44 are made of high-strength steel and wear-resistant alloy materials to ensure the stability and durability of the stacker crane during long-term use. The support platform 1 is made of high-strength carbon steel of type "Q345B", which has good compressive and impact resistance and can withstand the high loads generated during long-term use. The track 12 is made of wear-resistant alloy material, which has high corrosion resistance and friction resistance, ensuring that excessive wear will not occur during long-term use.

[0066] The pusher plate 44 is made of high-strength aluminum alloy, which not only possesses excellent mechanical properties but also reduces overall weight, improving the equipment's flexibility and response speed. The use of these high-quality materials in key components gives the stacker crane a longer service life and greater operational stability.

[0067] Comparative Cases:

[0068] Traditional stacker cranes typically use ordinary steel or materials with low wear resistance, which can lead to wear or damage to critical components during long-term operation, affecting equipment operating efficiency and material handling quality. Compared to traditional solutions, this embodiment significantly improves the stability and durability of the stacker crane by using high-strength steel and wear-resistant alloy materials, reducing maintenance costs and increasing production efficiency.

[0069] The working principle of this utility model is as follows:

[0070] In use, the first drive mechanism 3 and the second drive mechanism 5 work together to control the movement position of the push mechanism 4. Then, by controlling the extension and retraction of the cylinder 42, the angle between the deflector plate 43 and the second slide table 41 is adjusted, thereby adjusting the angle of the push plate 44. In this way, the products on the conveyor belt can be pushed to the next process.

[0071] The specific steps are as follows: when the product on the conveyor belt moves to the predetermined area, the first drive mechanism 3 drives the first slide table 2 to move on the track 12. When the push plate 44 is aligned with the product to be pushed, the movement stops.

[0072] Then, the second drive mechanism 5 controls the push mechanism 4 to slide on the first slide table 2, thereby allowing the push plate 44 to move closer to the product to be pushed and push the product to the next process.

[0073] During the process of the pusher plate 44 pushing the product, the cylinder 42 controls the elevation angle of the pusher plate 44, thereby enabling the pusher plate 44 to fit more closely with the product to be pushed.

[0074] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
