Description

TECHNICAL FIELD

[0002] With the rapid development of e-commerce, the transportation and sorting demand of packages has increased significantly, especially in the logistics distribution link, in order to improve efficiency, logistics enterprises have introduced automated loading equipment. The application of automated loading devices can significantly improve the processing efficiency of packages, reduce the tediousness of manual operation, and improve the operation speed of the overall logistics system. However, the existing automated cage loading device still has many technical bottlenecks in actual application, and needs to be improved.

[0003] At present, most cage loading devices adopt a turnover structure. This loading device automatically loads packages to the designated position by turning over the cage. Although this method has a certain degree of automation, in the actual operation process, the turnover loading device faces a series of safety hazards and operation instability problems. During the turnover process, due to the weight and structural characteristics of the cage itself, the center of gravity of the cage may be unstable, which increases the risk of the cage falling. This unstable condition not only may cause the packages in the cage to scatter and damage, but also may pose a safety threat to the operator and surrounding equipment.

DETAILED DESCRIPTION

[0028] In order to make the personnel in the technical field better understand the technical scheme in the utility model, the technical scheme in the embodiment of the utility model will be described clearly and completely below in combination with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the utility model.

[0029] Unless specifically stated otherwise, throughout the specification and claims, the term "comprising" or variations such as "comprise" or "comprises" will be understood to imply the inclusion of a stated element or group of elements but not the exclusion of any other element or group of elements.

[0030] With the rapid development of the logistics industry, especially e-commerce, the demand for package transportation and sorting is increasing year by year. How to efficiently and safely load and unload packages has become a technical problem to be solved. In the traditional cage loading and unloading method, a turnover structure is usually used to complete the loading. However, this method has certain safety hazards, especially when the center of gravity of the cage is unstable, which can easily cause the cage to tip over, and further cause the package to scatter, damage, or even harm the operator and surrounding equipment. Therefore, how to improve the loading and unloading efficiency while ensuring the safety of operation has become the driving force for technological innovation.

[0031] In view of the shortcomings of the existing technology, the utility model provides a cage loading and unloading device, which aims to avoid the turnover action in the traditional loading and unloading method by combining the translation and lifting mechanism, thereby solving the problems of unstable center of gravity and tipping over during the turnover of the cage. The core idea of the present invention is to use a translation mechanism to realize the horizontal movement of the cage, and to lift the cage smoothly by a lifting mechanism, so that the cage remains stable throughout the loading and unloading process. Through this design, the cage can not only effectively avoid the safety hazards caused by turnover, but also improve the loading and unloading efficiency, ensure the stability and reliability of the operation.

[0032] Specifically, the present invention moves the lifting trolley along the guide rail horizontally by the translation mechanism, and lifts the cage to the predetermined position by the lifting mechanism, completing the lifting and unloading process of the cage. The cooperation of the lifting platform and the lifting trolley can ensure the stability of the cage during the loading and unloading process, and the cooperative work of the translation mechanism and the lifting mechanism further improves the loading and unloading efficiency. In addition, the cage does not need to be turned over during the entire loading and unloading process, avoiding the problem of unstable center of gravity caused by turnover, thereby ensuring the safety of the package and the operator.

[0033] Please refer to Figure 1As shown, the cage loading and unloading device 100 in an embodiment of the utility model, including translation mechanism 1 and lifting mechanism 2.Translation mechanism 1 includes the first translation guide rail 11 and is arranged on the first translation guide rail 11 and can move along the first translation guide rail 11 lifting trolley 12, lifting trolley 12 includes the lifting platform 122 for lifting cage with liftable.Lifting mechanism 2 includes the lifting platform 21 for carrying cage with liftablely arranged in the rear end of the first translation guide rail 11, lifting platform 21 both sides are equipped with side support 211, tail is equipped with tail support 212, lifting platform 21 can be lifted to the height of the first translation guide rail 11 flush.Lifting platform 21 is lifted to the height of the first translation guide rail 11 flush, lifting trolley 12 can be moved to lifting platform 21, to lift the cage carried on lifting platform 21.

[0034] Translation mechanism 1 is one of the core components of the device, mainly by the first translation guide rail 11 and the lifting trolley 12 that can move along the first translation guide rail 11 are constituted.Lifting trolley 12 design ensures that cage can move smoothly along the first translation guide rail 11.Lifting platform 122 set on lifting trolley 12 has liftable function, can adjust lifting height according to the need.Through this lifting function, lifting trolley 12 can complete the loading and unloading work of cage with lifting mechanism 2.

[0035] Lifting mechanism 2 is realized through a lifting platform 21 to the vertical lifting of cage.Lifting platform 21 is arranged in the rear end of the first translation guide rail 11, and the height of lifting platform 21 can be adjusted along the vertical direction through the lifting device.Lifting platform 21 both sides are equipped with side support 211, and tail is equipped with tail support 212, and the function of these supports is to stabilize lifting platform 21 and support the cage above, prevent its inclination or instability in the lifting process.The lifting process of lifting platform 21 can be accurately controlled, ensure that lifting platform 21 can be lifted to the height of the first translation guide rail 11 flush, thereby relative to lifting trolley 12.

[0036] When lifting platform 21 is lifted to the height of the first translation guide rail 11 flush, lifting trolley 12 can move along the first translation guide rail 11 to lifting platform 21, so that cage is accurately placed on lifting platform 21.Lifting function of lifting trolley 12 can ensure the lifting stability of cage, and after lifting is completed, cage is transported from lifting platform 21 to translation mechanism 1.

[0037] The second translation rail 22 is arranged on the lifting platform 21. The second translation rail 22 provides a moving path for the lifting trolley 12, so that the lifting trolley 12 can move smoothly to the lifting platform 21 along the second translation rail 22 when the lifting platform 21 is lifted to the same height as the first translation rail 11. At this time, the second translation rail 22 is connected with the first translation rail 11 to form a continuous guide rail system, ensuring that the lifting trolley 12 can seamlessly move from the translation mechanism 1 to the lifting platform 21. The lifting platform 21 can be accurately adjusted to the same height as the first translation rail 11 by vertical lifting, so that the second translation rail 22 and the first translation rail 11 form a horizontal transition. The lifting operation of the lifting platform 21 can be controlled by an electric lifting system, which has high stability and accuracy, ensuring that the cage is always in a controllable and consistent height position during the entire loading and unloading process.

[0038] When the lifting platform 21 is lifted to the same height as the first translation rail 11, the translation trolley can move to the lifting platform 21 along the second translation rail 22, and continue to move along the guide rail to the bottom of the cage carried on the lifting platform 21. At this time, the lifting trolley 12 functions to lift the cage, ensuring that the cage is stably moved from the lifting platform 21 to the translation mechanism 1 for subsequent transportation operation. The lifting trolley 12 can lift the bottom of the cage through the lifting platform 122 arranged thereon.

[0039] In an exemplary embodiment, referring to Figure 1 As shown in FIG. 1, the front end of the first translation rail 11 is pivotally connected with a laterally extending first transmission shaft 14, and the first transmission shaft 14 is provided with a first driving sprocket 15. The rear end of the first translation rail 11 is provided with a first driven sprocket assembly 16, and the first driving sprocket 15 and the first driven sprocket assembly 16 are connected through a first transmission chain 17. The first transmission shaft 14 is connected with a first driving member 18, and the first transmission chain 17 is connected with the lifting trolley 12.

[0040] The first translation rail 11 is one of the basic structures of the entire translation system, and the front end thereof is pivotally connected with a laterally extending first transmission shaft 14. The first transmission shaft 14 functions to transmit power from the driving member to the transmission chain. Through the pivotal connection with the first translation rail 11, the transmission shaft can maintain a stable installation position and allow the horizontal or vertical force balance of the first transmission shaft 14 to be maintained during movement. The lateral extension design of the first transmission shaft 14 allows it to be reasonably arranged at the front end of the first translation rail 11 and effectively bear the subsequent transmission part.

[0041] On the first transmission shaft 14, a first drive sprocket 15 is installed, which is connected with a first transmission chain 17. The function of the first drive sprocket 15 is to convert the rotational power from the drive into linear motion of the chain through the meshing of gears and chains. The design of the transmission sprocket needs to match the size and tooth shape of the transmission chain to ensure that it can still maintain stable transmission efficiency under high load.

[0042] At the rear end of the first translation guide rail 11, a first driven wheel assembly 16 is provided. The function of this driven wheel assembly is to cooperate with the first drive sprocket 15 to complete the traction and return function of the transmission chain. The first driven wheel assembly 16 realizes the effective guidance of the chain through the contact with the transmission chain, and reduces the friction in the chain transmission process through its own rolling, ensuring the smooth movement of the lifting trolley 12.

[0043] The first drive sprocket 15 and the first driven wheel assembly 16 are connected through the first transmission chain 17 to form a complete chain drive transmission system. The advantage of chain transmission is its high efficiency of power transmission and strong load capacity, especially suitable for use in automated equipment that needs to operate for a long time and at high frequency. One end of the first transmission chain 17 is connected with the lifting trolley 12, which is ensured to move accurately and smoothly along the first translation guide rail 11 through the bracket or guide device on the trolley.

[0044] The power source of this transmission system comes from the first drive 18 connected with the first transmission shaft 14. The first drive 18 is usually a reduction motor, which functions to convert the high-speed low-torque power provided by the motor into low-speed high-torque output through a reduction device to drive the first transmission shaft 14 to rotate. The use of a reduction motor not only provides sufficient power as required, but also effectively avoids the vibration and noise caused by excessive speed, making the movement of the lifting trolley 12 more stable and accurate.

[0045] Specifically, please refer to Figure 2 The first driven wheel assembly 16 includes a first driven wheel 161, a tension seat 162, and a fixed seat 163. The first driven wheel 161 is pivoted to the tension seat 162, the tension seat 162 is fixed to the fixed seat 163, and the fixed seat 163 is fixed to the first translation guide rail 11.

[0046] The first driven wheel 161 is connected with the tensioning seat 162 through a pivoting structure, and can rotate freely when receiving the traction force of the first transmission chain 17, thereby driving the movement of the first transmission chain 17. The tensioning seat 162, through the pivoting structure with the first driven wheel 161, can keep the tension between the first driven wheel 161 and the first transmission chain 17 stable, preventing the transmission efficiency from being reduced or the slipping phenomenon from occurring due to the slack chain. In addition, the tensioning seat 162 can also adjust the tension of the first transmission chain 17, ensuring that the chain is always in an ideal tension state, thereby improving the stability of the entire system.

[0047] The fixed seat 163 is the basic support structure of the first driven wheel assembly 16, which is fixed on the first translation guide rail 11 and provides a stable support platform for the tensioning seat 162 and the first driven wheel 161. The function of the fixed seat 163 is not only to support the tensioning seat 162 and maintain the precise position of the first driven wheel 161, but also to withstand the torque and vibration generated during the transmission process of the driven wheel, ensuring the stability of the entire transmission system.

[0048] Further, as shown in Figure 2 , the tensioning seat 162 is provided with a waist-shaped hole 164 extending along the extension direction of the first translation guide rail 11, and the fixed seat 163 is provided with a screw hole 165 corresponding to the waist-shaped hole 164, and the screw bolt for fixedly connecting the tensioning seat 162 and the fixed seat 163 can pass through the waist-shaped hole 164 and be screwed into the screw hole 165.

[0049] During assembly, the screw bolt passes through the waist-shaped hole 164 and is screwed into the screw hole 165 on the fixed seat 163. Such a structure design can conveniently adjust the position of the tensioning seat 162, thereby accurately controlling the gap and alignment between the first driven wheel 161 and the first drive sprocket 15. Since the waist-shaped hole 164 allows a certain range of movement, the operator can adjust the position of the tensioning seat 162 to restore the ideal tension state when the chain tension is not appropriate or the chain is loose, ensuring the stable operation of the transmission system.

[0050] After a period of use, due to the wear of the chain or the change of the tensioning effect, it may be necessary to readjust the tension. At this time, by adjusting the position of the screw bolt and changing the distance between the tensioning seat 162 and the fixed seat 163, the service life and maintenance period of the system can be effectively prolonged without replacing parts.

[0051] In an exemplary embodiment, please refer to Figure 1 and Figure 3As shown, the lifting trolley 12 includes a chassis 121, a lifting platform 122, a lifter 123, and a connecting plate 124. The bottom of the chassis 121 is provided with guide rollers 125 matched with the first translation guide rail 11. The lifter 123 is arranged on the chassis 121. The lifting platform 122 is arranged on the lifter 123 and can be lifted relative to the chassis 121 under the action of the lifter 123. The connecting plate 124 is fixed on the chassis 121 and connected with the first transmission chain 17.

[0052] The chassis 121 of the lifting trolley 12 is the basis of its structure, and the chassis 121 is provided with guide rollers 125 matched with the first translation guide rail 11. The main function of these guide rollers 125 is to enable the lifting trolley 12 to move smoothly on the first translation guide rail 11. Through cooperation with the guide rail, the guide rollers 125 ensure the smooth operation of the lifting trolley 12 on the track, avoiding equipment wear or failure caused by friction or unstable operation, thereby improving the stability and operation efficiency of the entire system.

[0053] The lifter 123 of the lifting trolley 12 is arranged on the chassis 121, and the function of the lifter 123 is to realize the lifting of the lifting platform 122 relative to the chassis 121. The lifter 123 can be selected according to actual needs by using pneumatic, hydraulic or mechanical methods. Its main function is to provide sufficient power to enable the lifting platform 122 to be lifted in the vertical direction, thereby lifting the cage. When the lifting trolley 12 is driven by the first transmission chain 17 to move along the track to the lifting platform 21, the lifter 123 can ensure that the lifting platform 122 is lifted to the appropriate height, so that the lifting platform 122 contacts the bottom of the cage, thereby completing the lifting of the cage.

[0054] The lifting platform 122 can be customized according to the size and weight of the cage to ensure compatibility with different types of cages. The lifting platform 122 can be lifted relative to the chassis 121 under the action of the lifter 123, thereby moving the cage from the lifting platform 21 to the translation mechanism 1, or vice versa.

[0055] The connecting plate 124 is fixed on the chassis 121 and connected with the first transmission chain 17, so that the lifting trolley 12 can be driven by the first transmission chain 17 to move along the translation guide rail. The design of the connecting plate 124 can withstand the torque and tension during transmission to prevent loosening or breaking. Through the cooperation of the connecting plate 124 and the transmission chain, the lifting trolley 12 can accurately complete the movement task and accurately move the cage to the required position, ensuring the smooth progress of the entire loading and unloading process.

[0056] Specifically, please refer to Figure 3 and Figure 4As shown, the lifter 123 includes a scissor lifting assembly 31 and a driving motor 32 connected with the scissor lifting assembly 31 to drive the scissor lifting assembly 31 to lift. The scissor lifting assembly 31 is the core part of the lifter 123, mainly composed of a plurality of cross-connected support arms, which realizes lifting through the principle of scissor structure. Each support arm is composed of an upper support arm and a lower support arm, which form a scissor structure through an adjustable connecting rod.

[0057] When the driving motor 32 provides power, the scissor structure realizes stable lifting in the vertical direction through the staggered sliding principle of the support. The scissor lifting structure is widely used in equipment that needs large load and stable lifting due to its simple, stable and strong load-bearing characteristics. The scissor structure not only effectively disperses the load and reduces the pressure of a single support point, but also ensures the stability during lifting to avoid tilting or deviation caused by uneven stress.

[0058] In an exemplary embodiment, please refer to Figure 4 As shown, the scissor lifting assembly 31 includes a first scissor support arm 311, a second scissor support arm 312, and a lead screw 313 connected with the driving motor 32. The upper end and the lower end of the first scissor support arm 311 and the second scissor support arm 312 are engaged through a toothed structure. The first scissor support arm 311 and the second scissor support arm 312 are connected through the lead screw 313. The driving motor 32 drives the lead screw 313 to rotate to lift the first scissor support arm 311 and the second scissor support arm 312.

[0059] The first scissor support arm 311 and the second scissor support arm 312 are the core support parts of the scissor lifting assembly 31. Their upper ends and lower ends are engaged with each other through a toothed structure. The toothed structure design makes the connection between the two support arms more stable, can bear larger vertical load, and at the same time avoids the relative sliding or tilting between the support arms during lifting. The gear engagement structure can maintain high transmission accuracy and stability during lifting, ensure smooth transition of lifting action, and prevent lifting instability caused by uneven load or mechanical wear.

[0060] The connection mode of the first scissor support arm 311 and the second scissor support arm 312 is realized through the lead screw 313. The lead screw 313 is a kind of element that transmits through helical line form, which has high transmission accuracy and carrying capacity. In this device, the connection design of the lead screw 313 and the two support arms converts the rotary motion of the lead screw 313 into the translational motion of the support arm. During the rotation of the lead screw 313, the rotation of the lead screw 313 interacts with the support arm through the screw thread, pushes the support arm to staggered slide, thereby realizing the lifting of the lifting platform 122.

[0061] The driving motor 32 plays a role of power transmission in the system. The driving motor 32 transmits power to the screw rod 313 through a transmission device, drives the rotation of the screw rod 313, and thus drives the first and second scissor supporting arms 311 and 312 to ascend and descend. In order to ensure the stability and safety of the ascending and descending process, the driving motor 32 can be selected as an electric speed reducer, which can convert the high-speed rotation of the motor into a low-speed high-torque output suitable for the transmission of the screw rod 313, and ensure the stable operation in the ascending and descending process.

[0062] The connection mode of the screw rod 313 and the driving motor 32 can be driven through a shaft coupling or a direct connection bearing, which ensures high transmission efficiency and no significant gap, and reduces the instability caused by movement errors. The material and precision of the screw rod 313 can be selected according to the load requirements of the lifting platform 122, and high-strength steel and precision machining process are usually used to ensure its wear resistance and stability in long-term use.

[0063] Specifically, the upper end of the first and second scissor supporting arms 311 and 312 is connected with the support plate 126, and the lower end is connected to the chassis 121, and the support plate 126 is fixedly connected to the lifting platform 122.

[0064] The first and second scissor supporting arms 311 and 312 are connected through a toothed structure and form a support frame for scissor lifting together. Their upper ends are connected to the support plate 126, and their lower ends are fixed to the chassis 121. This structural relationship realizes that the supporting arms can generate a suitable motion trajectory in the lifting process, and ensures that the lifting platform 122 can keep vertical lifting without lateral deviation or instability. The design of the support plate 126 provides a stable support surface for the lifting process, avoiding the bending or deformation of the supporting arms in the lifting process.

[0065] The support plate 126 is not only the connection point of the supporting arms, but also the fixed base of the lifting platform 122. The connection mode between the support plate 126 and the lifting platform 122 needs to ensure that the lifting platform 122 can bear the load and keep stable in the lifting process. The support plate 126 is usually made of high-strength material to ensure that it will not deform or be damaged in the environment of high load or frequent lifting.

[0066] In an exemplary embodiment, please refer to Figure 1 and Figure 5As shown, the lifting mechanism 2 further includes a lifting rail 23, a connecting piece 24, and a second driving piece 25. The lower end of the lifting rail 23 is pivotally connected with a laterally extending second transmission shaft 26, and the second transmission shaft 26 is provided with a second driving sprocket 27. The upper end of the lifting rail 23 is provided with a second driven wheel assembly 28, and the second driving sprocket 27 and the second driven wheel assembly 28 are connected through a second transmission chain 29. The second transmission shaft 26 is in transmission connection with the second driving piece 25, the second transmission chain 29 is connected with the connecting piece 24, and the connecting piece 24 is connected with the lifting platform 21.

[0067] Specifically, the lifting rail 23 provides a vertical moving track for the lifting platform 21, and the connecting piece 24 transmits power from the second driving piece 25 to the lifting platform 21 through a transmission system, thereby driving the lifting platform 21 to lift. The lower end of the lifting rail 23 is pivotally connected with a laterally extending second transmission shaft 26, and the second transmission shaft 26 is provided with a second driving sprocket 27. The design of the second transmission shaft 26 can effectively transmit driving power from the second driving piece 25 to the second driving sprocket 27, providing power support for the lifting of the lifting platform 21. The upper end of the lifting rail 23 is provided with a second driven wheel assembly 28, and the driven wheels play a role in guiding and fixing the second transmission chain 29, so that the transmission chain can run stably without deviation or friction loss.

[0068] The second driving sprocket 27 and the second driven wheel assembly 28 are connected through the second transmission chain 29 to form a complete transmission loop. The second transmission chain 29 transmits the rotating power from the second driving piece 25 to the connecting piece 24, thereby driving the connecting piece 24 to lift along the lifting rail 23. The connecting piece 24 can move more smoothly on the lifting rail 23 through the pulley matched with the lifting rail 23. The pulley not only reduces friction but also improves the overall efficiency of the system, making the lifting process more smooth and stable.

[0069] The transmission connection between the second transmission shaft 26 and the second driving piece 25 is the power source of the entire lifting system, and the second driving piece 25 is usually a motor or other type of driving device. The output power of the motor is transmitted to the lifting system through the second transmission shaft 26 and the second driving sprocket 27, so that the lifting platform 21 lifts in the vertical direction.

[0070] The connection between the connecting piece 24 and the lifting platform 21 enables the lifting platform 21 to closely cooperate with the lifting mechanism 2. The design of the connecting piece 24 ensures that its structural strength can withstand the weight and load of the lifting platform 21, thereby improving the lifting efficiency and stability. The pulley of the connecting piece 24 cooperates with the lifting rail 23 to enable the lifting platform 21 to lift smoothly in the vertical direction, avoiding the problems of jamming or damage that may occur during lifting.
