Description

Technical Field

[0001] This utility model relates to the field of stacking machine technology, specifically a fully automatic stacking machine. Background Technology

[0002] In today's logistics, warehousing, transportation, and various manufacturing sectors, pallets serve as a crucial carrier for goods storage and handling, with massive and indispensable usage. Traditional manual pallet handling and stacking methods have many drawbacks: low efficiency, high labor intensity, and susceptibility to human error leading to pallet damage or uneven stacking, thus affecting the safety of goods storage and transportation. With the continuous development of automation technology, the market demand for equipment capable of efficiently, accurately, and stably completing pallet stacking tasks is becoming increasingly urgent, giving rise to fully automatic pallet stacking machines.

[0003] The function of an automatic pallet stacker is to stack individual pallets together into a whole, which facilitates storage and transportation, while making full use of storage space.

[0004] In the prior art, there is a Chinese patent with authorization announcement number CN219652213U entitled "A Fully Automatic Destacking and Stacking Machine". The patent discloses a fully automatic destacking and stacking machine, which includes a fixed frame. A connecting frame is fixedly connected to the bottom of the fixed frame. A caster wheel is installed on the bottom end face of the connecting frame. A first servo motor is fixedly installed on the side end face of the connecting frame. The output end of the first servo motor is connected to a bidirectional threaded rod. A sliding plate is threadedly connected to the bidirectional threaded rod.

[0005] The aforementioned patent utilizes a bidirectional threaded rod to rotate, enabling sliding plates connected by threads on both sides to move simultaneously towards the center or sides, increasing the versatility and convenience of the fully automatic pallet stacking machine. However, in existing technologies such as the aforementioned patent, the automation level of some devices is not high enough, still requiring manual intervention in some operational steps. For example, when it is necessary to lift the pallet, fasteners need to be used to fix the pallet before it can be driven upwards. This not only reduces overall work efficiency but may also affect the stacking quality due to the instability of manual operation. Utility Model Content

[0006] The purpose of this invention is to provide a fully automatic tray stacking machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic pallet stacking machine, comprising a conveyor frame and a first support mounted on the conveyor frame, wherein a pallet body is conveyed on the conveyor frame, a second support is slidably connected to the first support, a stacking mechanism is provided on the second support, a pallet hole is provided on the pallet body, and the stacking mechanism is intermittently engaged in the pallet hole; a lifting mechanism for driving the second support to slide vertically is provided on the first support.

[0008] Furthermore, the stacking mechanism includes rotating rods rotatably connected to both sides of the second support, each rotating rod being fixedly connected to a bearing rod, the bearing rod engaging with a tray hole; the second support is also provided with a rotary motor for driving the rotating rods to rotate, the rotary motor driving the rotating rods to rotate via a linkage.

[0009] Furthermore, the linkage includes a first sprocket mounted on a rotating rod, a second sprocket on the output end of the rotary motor, and a chain sleeved between the second sprocket and multiple first sprockets.

[0010] Furthermore, guide transmission components are also provided on both sides of the second bracket.

[0011] Furthermore, the lifting mechanism includes a rotating shaft rotatably connected to a first bracket, a protrusion provided on the rotating shaft, and a drive ring provided on the side of the protrusion away from the rotating shaft, the drive ring abutting against a second bracket; a lifting motor for driving the rotating shaft to rotate is provided on the first bracket.

[0012] Furthermore, there are two rotating shafts, which are rotatably connected to both sides of the second bracket, and the output end of the lifting motor is connected to the two rotating shafts through a linkage.

[0013] Furthermore, multiple limiting components are provided between the first bracket and the second bracket.

[0014] Furthermore, the limiting component includes a limiting post fixedly connected to the first bracket, and a limiting sleeve is provided on the second bracket, with the limiting post and the limiting sleeve being slidably connected.

[0015] Furthermore, a locking plate is fixedly connected to the second bracket, and the drive ring is locked onto the locking plate.

[0016] Furthermore, side plates are provided on both sides of the conveyor frame.

[0017] Compared with existing technologies, the advantages of this invention are as follows: This fully automatic pallet stacking machine, through the cooperation of a first support, a second support, a stacking mechanism, and a lifting mechanism, operates as follows: During use, the stacking mechanism engages with the pallet through the pallet hole.

The next pallet on the conveyor frame then moves directly beneath the first pallet. At this point, the stacking mechanism is rotated to move away from the pallet hole. The lifting mechanism then resets the second support. This process is repeated to achieve pallet stacking. In this process, automatic pallet positioning, engagement, and lifting / stacking are achieved without manual operation of fasteners or auxiliary positioning, significantly improving stacking efficiency, reducing labor intensity, greatly enhancing work efficiency and automation levels, and ensuring the consistency and reliability of the stacking process.

[0021] 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.

[0022] Please see Figures 1-7 This utility model provides a technical solution: a fully automatic pallet stacking machine, including a conveyor frame 14 and a first support 1 installed on the conveyor frame 14. The conveyor frame 14 conveys a pallet body 2. A second support 3 is slidably connected to the first support 1. A stacking mechanism is provided on the second support 3. The pallet body 2 has a pallet hole 21. The stacking mechanism is intermittently engaged in the pallet hole 21. A lifting mechanism 4 is provided on the first support 1 for driving the second support 3 to slide vertically.

[0023] Specifically, this fully automatic pallet stacking machine includes a conveyor frame 14 and a first support 1 mounted on the conveyor frame 14. The conveyor frame 14 conveys pallet bodies 2. Specifically, the conveyor frame 14 is equipped with a conveying mechanism for conveying the pallet bodies 2. The conveying mechanism is existing technology, and its structure and working principle will not be described in detail here. A second support 3 is slidably connected to the first support 1. The second support 3 is equipped with a stacking mechanism. The pallet body 2 has a pallet hole 21. The stacking mechanism intermittently engages with the pallet hole 21. When the stacking mechanism is engaged with the pallet hole 21, driving the second support 3 to move upward will also drive the pallet body 2 to move upward. The first support 1 is equipped with a lifting mechanism 4 for driving the second support 3 to slide vertically, providing a power source for the upward movement of the second support 3, resulting in better performance. In use, the stacking mechanism engages with the pallet through the tray hole 21. Then, the lifting mechanism 4 drives the second support 3 to slide on the first support 1, moving it upwards a certain distance. Afterwards, the next pallet on the conveyor frame 14 moves directly beneath the first pallet. At this point, the stacking mechanism is rotated to move away from the tray hole 21. Then, the lifting mechanism 4 drives the second support 3 to reset. This process is repeated to stack the pallet body 2. This process achieves automatic pallet positioning, engagement, and lifting / stacking, eliminating the need for manual operation of fasteners or auxiliary positioning. It significantly improves stacking efficiency, reduces labor intensity, greatly enhances work efficiency and automation, and ensures the consistency and reliability of the stacking process.

[0024] In the embodiments provided by this utility model, the stacking mechanism includes rotating rods 8 rotatably connected to both sides of a second support 3. Each rotating rod 8 is fixedly connected to a bearing rod 9, which engages with a tray hole 21. A rotary motor 10 is also provided on the second support 3 to drive the rotating rods 8 to rotate. The rotary motor 10 drives the rotating rods 8 to rotate via a linkage 11. By driving the rotating rods 8 to rotate via the rotary motor 10, the movement of the bearing rods 9 into or out of the tray hole 21 can be precisely controlled, achieving automatic engagement and disengagement with the tray. The movement is precise and the power is sufficient. Motor-driven operation is more suitable for automated processes than purely mechanical or manual control.

[0025] In the embodiments provided by this utility model, the linkage 11 includes a first sprocket mounted on the rotating rod 8, a second sprocket is provided on the output end of the rotary motor 10, and a chain is sleeved between the second sprocket and multiple first sprockets. By adopting chain drive, it can ensure that one rotary motor 10 can simultaneously drive multiple rotating rods 8 on both sides to rotate synchronously, thereby ensuring that all bearing rods 9 can perform the locking or disengaging action simultaneously and synchronously.

[0026] In the embodiments provided by this utility model, guide transmission components 12 are also provided on both sides of the second bracket 3. Specifically, the guide transmission component 12 includes a mounting rod installed on the second bracket 3, and a third sprocket is provided on the mounting rod. The chain is sleeved between the first sprocket, the second sprocket and the third sprocket to achieve a guiding effect.

[0027] In the embodiments provided by this utility model, the lifting mechanism 4 includes a rotating shaft 42 rotatably connected to a first bracket. A protrusion 43 is provided on the rotating shaft 42, and a drive ring 44 is provided on the side of the protrusion 43 away from the rotating shaft 42. The drive ring 44 abuts against the second bracket 3. A lifting motor for driving the rotating shaft 42 is provided on the first bracket 1. There are two rotating shafts 42, rotatably connected to both sides of the second bracket 3 respectively. The output end of the lifting motor is connected to the two rotating shafts 42 via a linkage 45. The rotation of the lifting motor's rotating shaft is ensured by the linkage 45 to synchronously drive the rotating shafts 42 on both sides by one lifting motor. This symmetrical design makes the lifting force distribution more uniform, avoiding the jamming or tilting problems that may occur in the second bracket 3 due to unilateral force during the lifting process, significantly enhancing the stability and reliability of the lifting process.

[0028] In the embodiments provided by this utility model, a plurality of limiting components are also provided between the first support 1 and the second support. The limiting components include a limiting post 5 fixedly connected to the first support, and a limiting sleeve 6 provided on the second support. The limiting post 5 and the limiting sleeve 6 are slidably connected. The sliding cooperation between the limiting post 5 and the limiting sleeve 6 mainly restricts the sliding stroke of the second support 3 relative to the first support 1, prevents it from overtraveling or falling out, and ensures the safety of equipment operation. At the same time, it can also enhance the overall rigidity and stability of the connection between the first support 1 and the second support 3 to a certain extent.

[0029] In the embodiment provided by this utility model, a locking plate 7 is fixedly connected to the second bracket 3, and the drive ring 44 is locked onto the locking plate 7. By setting a special locking plate 7 for the drive ring 44 to lock onto, the pushing force of the lifting mechanism 4 is transmitted to the second bracket 3 more smoothly and more concentratedly, so as to better drive the second bracket 3 to slide on the first bracket 1.

[0030] In the embodiments provided by this utility model, side plates 13 are provided on both sides of the conveyor frame 14. The main function of the side plates 13 is to limit and guide the pallet body 2 on the conveyor frame 14 laterally, so as to prevent the pallet from running off course, misaligning, or falling off the conveyor frame 14 during the conveying process.

[0031] It should be noted that all electrical equipment involved in this application can be powered by batteries or external power sources, and this application is equipped with a control system for controlling the operation of the entire equipment.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
