Description

Technical Field

[0001] This utility model relates to the field of mechanical tooling technology, specifically to a stacking mechanism for a pump assembly feeding tray. Background Technology

[0002] In existing technologies, the palletizing process of the material trays in the pump assembly production process has always been a key factor affecting production efficiency and product quality. Traditional palletizing methods rely heavily on manual operation, which is not only labor-intensive and inefficient, but also prone to problems such as tray tipping and misalignment during the palletizing process, leading to production interruptions or even product damage. In addition, manual palletizing makes it difficult to guarantee the positional accuracy of each tray, thus affecting the accuracy and stability of subsequent assembly processes. Summary of the Invention

[0003] In view of this, the present invention provides a stacking mechanism for a pump assembly feeding tray.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A stacking mechanism for a pump assembly feeding tray includes an empty tray unit and a full tray unit. A conveying device is provided between the empty tray unit and the full tray unit. Several stacked trays are placed on the empty tray unit. An empty tray locking component is provided on the empty tray unit to lock the empty trays. The trays on the empty tray unit are conveyed to the full tray unit for loading and the loaded trays are locked.

[0006] Preferably, the empty tray unit includes an empty tray bracket and an empty tray lifting device. The empty tray bracket is arranged in a ring structure. The empty tray locking component is disposed on the edge of the empty tray bracket and has a locking support end. The tray is disposed on the locking support end and the locking support end supports the tray. The empty tray lifting device is disposed at the bottom of the empty tray bracket. One end of the empty tray lifting device abuts against the tray and drives the tray to move from above the empty tray bracket toward the conveying device until it is placed on the conveying device.

[0007] Preferably, the empty tray locking assembly includes a locking block, a guide seat, a slider, and a slider power source. The empty tray bracket has a slider movable groove, and the slider is movably disposed in the slider movable groove. The slider power source is disposed at the bottom of the slider and connected to the slider. The slider power source drives the slider to move within the slider movable groove. The locking block is disposed on the slider, and the locking support end is formed on the side of the locking block near the tray.

[0008] Preferably, the guide seat is fixed to the top of the empty disc bracket, and a guide groove communicating with the movable groove is provided on the guide seat. The slider can move between the guide groove and the movable groove. A locking block moving groove is provided on the slider. A positioning pin is provided in the locking block moving groove. The positioning pin is connected to the locking block. During the movement of the slider, the positioning pin moves along the locking block moving groove, thereby driving the locking block to move.

[0009] Preferably, the full-load unit includes a tray support, a self-locking component mounted on the tray support, and a full-load lifting device mounted at the bottom of the tray support. The full-load lifting device lifts the tray on the conveying device so that the tray moves towards the upper part of the tray support. After the tray moves to the upper part of the tray support, the self-locking component on the tray support supports and limits the tray.

[0010] Preferably, the self-locking assembly includes a self-locking fixing block and a self-locking block. The self-locking fixing block has a rotating groove with an opening facing the center of the tray support. The self-locking block is rotatably disposed in the rotating groove. The self-locking block has a supporting surface and a guiding inclined surface. The supporting surface supports the tray. During the rising process of the tray, it contacts the inclined surface and drives the self-locking block to rotate towards the upper part of the tray support. Subsequently, the self-locking block returns to its original position and supports and limits the tray after it has been loaded by the supporting surface.

[0011] Preferably, the conveying device includes a lead screw, a motor, and a conveying tray. One end of the lead screw is connected to the motor, and the conveying tray is mounted on the lead screw. The material tray on the empty tray unit descends onto the conveying tray and is conveyed to the full tray unit via the conveying tray.

[0012] The beneficial effects of this invention are as follows: By setting up independent empty tray units and full tray units, combined with a precise conveying device, efficient flow of trays from empty to full states is achieved. The empty tray locking component on the empty tray unit can limit and support several stacked trays on the empty tray unit, preventing chaos or tipping when one tray is being conveyed and the other empty trays descend, thus ensuring the stability and safety of tray conveying. After receiving the tray from the empty tray unit, the full tray unit performs a loading operation, and after loading, a corresponding locking device is also set on the full tray to lock it again, preventing material spillage or tray displacement during subsequent handling or storage. This palletizing mechanism design not only improves the efficiency of tray palletizing but also greatly enhances the reliability and stability of the entire palletizing process, providing strong support for the automated handling of trays unloading from the pump assembly.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] This utility model provides the following technical solution:

[0021] As attached Figure 1-4As shown, this utility model discloses a stacking mechanism for a pump assembly unloading tray, including an empty tray unit 1 and a full tray unit 2. A conveying device 3 is provided between the empty tray unit 1 and the full tray unit 2. Several stacked trays 4 are placed on the empty tray unit 1. An empty tray locking component 5 is provided on the empty tray unit 1 to lock the empty trays 4. The trays 4 on the empty tray unit 1 are conveyed to the full tray unit 2 by the conveying device 3 for loading and locking the loaded trays 4. Specifically, in this design, by setting up independent empty tray units 1 and full tray units 2, and cooperating with a precise conveying device 3, efficient flow of trays 4 from empty to full is achieved. The empty tray locking component 5 on the empty tray unit 1 can limit and support the several stacked trays 4 on the empty tray unit 1, preventing the other empty trays 4 from descending and causing chaos or tipping when one tray 4 is being conveyed, thus ensuring the stability and safety of the tray 4 conveying. After receiving the material tray 4 from the empty tray unit 1, the full-loading unit 2 performs a loading operation. After loading, a locking device is installed on the full-loading unit 2 to re-lock the material tray 4, preventing spillage or displacement of the tray 4 during subsequent handling or storage. This palletizing mechanism design not only improves the efficiency of pallet 4 palletizing but also greatly enhances the reliability and stability of the entire palletizing process, providing strong support for the automated handling of the pump assembly's unloading tray 4.

[0022] Furthermore, the empty tray unit 1 includes an empty tray bracket 6 and an empty tray lifting device 7. The empty tray bracket 6 is arranged in a ring structure. The empty tray locking component 5 is disposed on the edge of the empty tray bracket 6. The empty tray locking component 5 has a locking support end 8. The tray 4 is disposed on the locking support end 8, which supports the tray 4. The empty tray lifting device 7 is disposed at the bottom of the empty tray bracket 6. One end of the empty tray lifting device 7 abuts against the tray 4 and drives the tray 4 to move from above the empty tray bracket 6 toward the conveying device 3 until it is placed on the conveying device 3. Specifically, in this embodiment, the empty tray bracket 6 adopts a ring structure design. The hollow part in the middle is used for lifting and lowering the tray 4 to avoid interference. The locking support end 8 on the empty tray locking component 5 extends toward the hollow part in the middle to provide stable support for the tray 4, ensuring that the tray 4 will not slide or deviate arbitrarily on the empty tray bracket 6. The empty tray lifting device 7 precisely controls the lifting height and speed of the tray 4 according to actual needs. When the tray 4 needs to be transported, the empty tray lifting device 7 lifts the tray 4 upward, causing the tray 4 to disengage from the locking support end 8, and moves towards the conveying device 3 under its push until it is stably placed on the conveying device 3, completing the transfer process of the empty tray from the empty tray unit 1 to the conveying device 3. This design enables the empty tray unit 1 to provide empty trays 4 to the conveying device 3 in an orderly and stable manner, preparing for subsequent full-load operations.

[0023] Furthermore, the empty tray locking assembly 5 includes a locking block 9, a guide seat 10, a slider 11, and a slider power source 12. The empty tray bracket 6 has a slider movement groove 13. The slider 11 is movably disposed within the slider movement groove 13. The slider power source 12 is located at the bottom of the slider 11 and connected to it. The slider power source 12 drives the slider 11 to move within the slider movement groove 13. The locking block 9 is disposed on the slider 11, and the locking support end 8 is formed on the side of the locking block 9 near the tray 4. The slider power source drives the slider to move, and the locking block's position fixed in the slider movement groove changes accordingly based on the slider's movement. Specifically, in this embodiment, after the slider power source 12 is activated, it drives the slider 11 to move precisely within the slider movement groove 13. Since the locking block 9 is disposed on the slider 11, it moves along with the slider 11. When it is necessary to lock the tray 4, the slider power source 12 drives the slider 11 to move, so that the locking support end 8 on the locking block 9 approaches and contacts the tray 4, forming a stable support and lock for the tray 4, preventing the tray 4 from sliding or shifting on the empty tray bracket 6. When it is necessary to transport the tray 4, the slider power source 12 moves again, driving the slider 11 to move in the opposite direction, so that the locking support end 8 on the locking block 9 moves away from the tray 4, releasing the lock on the tray 4. At this time, the empty tray lifting device 7 can smoothly lift the tray 4 and transport it to the conveying device 3. This design is not only compact and easy to operate, but also ensures the stability and safety of the tray 4 on the empty tray unit 1, providing a reliable guarantee for subsequent palletizing operations. Furthermore, in this design, the actions between the slider power source and the empty tray lifting device 7 are synchronized. Through preset program control, when the slider power source drives the slider 11 to move and release the lock on the tray 4, the empty tray lifting device 7 will start immediately, lifting the tray 4 onto the conveying device 3 with precise synchronous action. This synchronous control mechanism effectively avoids tray jamming or damage caused by asynchronous actions, further improving the smoothness and reliability of the entire palletizing process. At the same time, the design also considers the stability and durability of the equipment; all components are manufactured using high-quality materials to ensure stable performance even during long-term continuous operation. The sliding block is powered by a cylinder.

[0024] Furthermore, the guide seat 10 is fixed to the top of the empty tray bracket 6. A guide groove 15 is formed on the guide seat 10, connecting to the slider movable groove 13. The slider 11 can move between the guide groove 15 and the slider movable groove 13. A locking block moving groove 16 is formed on the slider 11, and a positioning pin is provided within the locking block moving groove 16. The positioning pin is connected to the locking block 9. During the movement of the slider 11, the positioning pin moves along the locking block moving groove 16, thereby driving the locking block 9 to move. Specifically, in this embodiment, the guide seat 10, through the guide groove 15, provides a clear movement path for the slider 11, ensuring the stability and accuracy of the slider 11 during movement. Simultaneously, the locking block moving groove 16 on the slider 11 and the positioning pin inside form a tight linkage mechanism with the locking block 9. When the slider 11 moves between the guide groove 15 and the slider movable groove 13, the positioning pin moves accordingly along the locking block moving groove 16, thereby driving the locking block 9 to move precisely.

[0025] Furthermore, the full-load unit 2 includes a tray support 17, a self-locking component 18 mounted on the tray support 17, and a full-load lifting device 19 located at the lower part of the tray support 17. The full-load lifting device 19 lifts the tray 4 on the conveying device 3, causing the tray 4 to move upwards towards the tray support 17. After the tray 4 moves to the upper part of the tray support 17, the self-locking component 18 on the tray support 17 supports and limits the tray 4. Specifically, in this embodiment, the tray support 17 is also arranged in a ring structure, with a hollow area in the middle providing sufficient space for the lifting and lowering of the tray 4, avoiding interference between components. When the conveying device 3 transports the tray 4 filled with material to the lower part of the full-load unit 2, the full-load lifting device 19 is activated, lifting the tray 4 upwards and gradually moving it towards the upper part of the tray support 17. During the ascent of pallet 4, the self-locking component 18 remains in standby mode. Once pallet 4 reaches the designated position on the upper part of pallet holder 17, the self-locking component 18 immediately activates, providing stable support and limiting the pallet 4 to prevent it from sliding, shifting, or tipping over during subsequent handling or storage, thus ensuring the stability and safety of pallet 4 after it is full. This design of the full-load unit 2, working in conjunction with the empty pallet unit 1, completes the entire pallet 4 palletization process from empty to full. The seamless integration and smooth operation of each step significantly improves palletizing efficiency.

[0026] Furthermore, the self-locking assembly 18 includes a self-locking fixing block 20 and a self-locking block 21. The self-locking fixing block 20 has a rotating groove 22 with its opening facing the center of the tray support 17. The self-locking block 21 is rotatably disposed within the rotating groove 22. The self-locking block 21 has a supporting surface 23 and a guiding inclined surface 24. The supporting surface 23 supports the tray 4. During the upward movement of the tray 4, it contacts the inclined surface and drives the self-locking block 21 to rotate towards the upper part of the tray support 17. Subsequently, the self-locking block 21 returns to its original position and supports and limits the loaded tray 4 through the supporting surface 23. Specifically, in this embodiment, the self-locking fixing block 20 serves as the basic part of the self-locking assembly 18, and the rotating groove 22 on it provides a stable rotation space for the self-locking block 21. The opening of the rotating groove 22 is positioned facing the center of the tray support 17. This design allows the self-locking block 21 to smoothly contact and rotate with the tray 4 during the upward movement of the tray 4. The self-locking block 21, as the core component of the self-locking assembly 18, has two key parts: a support surface 23 and a guide inclined surface 24. The support surface 23 provides stable support and limits the loaded tray 4 after the self-locking block 21 returns to its original position, ensuring the stability and safety of the tray 4 when it is full. The guide inclined surface 24 guides the tray 4 upwards and drives the self-locking block 21 to rotate. As the tray 4 gradually rises under the support of the full-load lifting device 19, its bottom will first contact the guide inclined surface 24 of the self-locking block 21. As the tray 4 continues to rise, the guide inclined surface 24 guides the self-locking block 21 to rotate towards the upper part of the tray support 17, making room for the tray 4 to rise smoothly. When the tray 4 rises to the designated position, the self-locking block 21 returns to its original position under the action of gravity or a spring-like reset mechanism. At this time, its support surface 23 will be aligned with the bottom of the tray 4, providing stable support and limiting for the tray 4.

[0027] Furthermore, the conveying device 3 includes a lead screw 25, a motor 26, and a conveying tray 27. One end of the lead screw 25 is connected to the motor 26, and the conveying tray 27 is mounted on the lead screw 25. The material tray 4 on the empty tray unit 1 descends onto the conveying tray 27 and is conveyed to the full material unit 2 via the conveying tray 27. Specifically, in this embodiment, the motor 26 serves as the power source for the conveying device 3, and its operation drives the lead screw 25 to rotate. The rotational motion of the lead screw 25 is converted into the linear motion of the conveying tray 27, enabling the conveying tray 27 to move smoothly along a predetermined path. When the material tray 4 on the empty tray unit 1 descends onto the conveying tray 27 under the action of the empty tray lifting device 7, the motor 26 starts, and the lead screw 25 drives the conveying tray 27 to slowly move towards the full material unit 2. During the movement, the conveying tray 27 remains horizontal, ensuring that the material tray 4 will not spill material or shift due to shaking or tilting. The size and shape of the conveyor tray 27 are customized according to the dimensions of the material tray 4 to ensure that the material tray 4 can be stably placed on the conveyor tray 27. The motor 26 is a reversible motor. By controlling the forward and reverse rotation, the motor 26 can flexibly adjust the moving direction of the conveyor tray 27. When an empty tray needs to be conveyed from the empty tray unit 1 to the full material unit 2, the motor 26 rotates forward, driving the lead screw 25 to move the conveyor tray 27 towards the full material unit 2; when the full material unit 2 has completed the loading operation and the full material tray 4 needs to be conveyed to the next process or storage area, the motor 26 reverses, causing the conveyor tray 27 to return along the original path or move to the designated position. This reversible design greatly improves the flexibility and versatility of the conveyor device 3, enabling it to adapt to the conveying needs in different scenarios.

[0028] Both the empty pallet lifting device 7 and the full material lifting device 19 can be common hydraulic lifting devices or electric push rod lifting devices in the prior art, so they will not be described in detail here.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
