Description

Technical Field

[0001] This invention relates to the field of logistics and transportation, and specifically to a lifting and output device for palletizing inside a container. Background Technology

[0002] In-container palletizing technology serves relatively enclosed and orderly work spaces, such as inside shipping containers or relatively orderly transshipment containers, allowing items to be neatly stacked in the work space to improve work efficiency and replace manual labor.

[0003] Existing technologies for in-box palletizing have evolved to fully automated palletizing capabilities, but this is limited by the requirement that the working space and the size of the in-box palletizing equipment correspond; otherwise, manual intervention is necessary. This correspondence includes ensuring that the width of the palletizing area corresponds to the width of the working space, thus guaranteeing that items can reach all parts of the working space. The in-box palletizing equipment has a lifting and output device at its gantry structure. After the items reach the lifting and output device, they are placed at the required working height through lifting or lowering operations. Simultaneously, the lifting and conveying device horizontally moves the items, aligning them with the placement area. Finally, the lifting and conveying device pushes the items into the placement area, facilitating the stacking of previously placed items.

[0004] When the lifting and output device is inside the compartment, if the working space inside the compartment is wide, then the lifting and output device needs to be extended laterally to increase the lateral dimension of the working area of ​​the lifting and output device in order to move items in the horizontal direction.

[0005] For example, the Chinese patent application CN202310364086.5, published on August 1, 2023, entitled "A Front-End Loading Device for an In-Box Palletizing Equipment," describes a lateral expansion component that obtains a portion of the lateral expansion by flipping and then obtains the remaining lateral expansion by hinge-type extension. The minimum and maximum values ​​of this lateral expansion are discontinuous because a portion of the lateral expansion comes from the flipping action of the lateral expansion component, resulting in a sudden increase and discontinuous change in the lateral expansion. This characteristic limits the applicability of the lifting and output device. Furthermore, since the lateral expansion component is located at both ends of the support body laterally, meaning that the lateral expansion support is suspended at one end after lateral extension, it can deform when transporting heavy objects. Summary of the Invention

[0006] The purpose of this invention is to provide a lifting and output device for palletizing inside a compartment, which can effectively solve the problem that existing lifting and output devices for palletizing inside a compartment are in a state of suspension at one end after being extended laterally, which causes deformation of the lateral extension component when transporting heavy objects.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0008] A palletizing lifting and output device for use in a compartment includes a main frame and a pushing component. The pushing component includes a pushing actuator, a fixed bearing assembly, and a movable bearing assembly. Both the fixed bearing assembly and the movable bearing assembly are provided with a plurality of parallel rotating rollers, the axes of which are arranged longitudinally. The fixed bearing assembly is fixed to the main frame, and the movable bearing assembly is slidably disposed on the main frame and located on both sides of the fixed bearing assembly. A first telescopic assembly is provided between the fixed bearing assembly and the movable bearing assembly. The moving range of the pushing actuator is located above the fixed bearing assembly and the movable bearing assembly.

[0009] Preferably, the fixed load-bearing assembly has two sets of movable load-bearing assemblies at each end along the lateral direction, namely a first movable load-bearing assembly and a second movable load-bearing assembly. The first movable load-bearing assembly is connected to the fixed load-bearing assembly through one set of first telescopic components, and the second movable load-bearing assembly is connected to the first movable load-bearing assembly through another set of first telescopic components. Each end has two sets of movable load-bearing assemblies, thereby further expanding the lateral adjustable range. Furthermore, the movable load-bearing assemblies are also connected to each other through first telescopic components. This facilitates adjustment of the adjustment range of adjacent movable load-bearing assemblies while reducing the number of different parts used in the device, thus reducing manufacturing costs.

[0010] Preferably, the main frame is further fixed with a transverse drive motor and a lead screw driven by the transverse drive motor. The lead screw has a first external thread corresponding to the position of the first movable bearing component, and the first movable bearing component is threadedly connected to the first external thread. The lead screw also has a second external thread corresponding to the position of the second movable bearing component, and the second movable bearing component is threadedly connected to the second external thread. The pitch of the first external thread is smaller than the pitch of the second external thread. The lead screw allows for synchronous adjustment of the transverse movement of all movable bearing components. Furthermore, since the first and second movable bearing components are at different distances from the fixed bearing component, by setting two external threads with different pitches corresponding to the two movable bearing components respectively, different extension and retraction speeds can be achieved for the two movable bearing components, resulting in a better transverse adjustment range.

[0011] Preferably, the pushing component further includes a synchronous drive motor, and the pushing actuator includes a first push plate and a second push plate. The first push plate is located above the fixed support component, and the second push plate is distributed above the outermost movable support component. A synchronous drive motor for driving the second push plate to slide longitudinally is fixed on the movable support component below the second push plate. The first push plate and the second push plate are slidably connected to achieve lateral movement of the second push plate relative to the first push plate. Distributing the second push plate above the outermost movable support component ensures that items on the movable support component can be pushed away after the movable support component moves laterally outward. Fixing the synchronous drive motor on the movable support component below the second push plate can maximize the clearance of the middle area and avoid interference with the components below the fixed support component. When the synchronous drive motor pushes the second push plate, the second push plate will drive the first push plate to slide longitudinally, so that all goods on the fixed support component and the movable support component are pushed away.

[0012] Preferably, a first guide rod is fixed to the fixed support assembly below the first push plate, and the first push plate is slidably mounted on the corresponding first guide rod; a first guide rod is also fixed to the movable support assembly below the second push plate, and the second push plate is slidably mounted on the corresponding first guide rod. The synchronous drive motor drives the pushing actuator to slide along the first guide rod via a synchronous belt. By setting multiple longitudinally arranged first guide rods below the first and second push plates, the movement path of the first and second push plates is restricted, ensuring that the first and second push plates can move in a straight line to push the item away from the support assembly.

[0013] Preferably, the palletizing lifting and output device inside the compartment further includes a support assembly located below the rotating roller. The support assembly includes an outer spline rod, an inner spline tube, a support rod drive motor, and several support rods arranged parallel to each other in the transverse direction. Multiple support rods are fixed to a fixed plate to form a support rod assembly. A set of support rod assemblies is provided on both the fixed support assembly and each movable support assembly. The outer spline rod is sleeved with the inner spline tube and remains relatively stationary in the circumferential direction. The outer spline rod can slide laterally relative to the inner spline tube. Each set of support rod assemblies is connected to the outer spline rod or the inner spline tube through a transmission component. The support rod drive motor is fixed to the main frame or the fixed support assembly. The support rod drive motor drives the inner spline tube or the outer spline rod to rotate, thereby driving the support rod assembly to slide longitudinally out of the corresponding fixed support assembly or movable support assembly. The support component is used to reduce the height difference of the item falling from the support component, and plays a supporting role in the middle, thereby preventing damage when the item is pushed away. The support component drives the spline rod to rotate through the tow rod drive motor, which drives all the tow rods to move longitudinally. Since the movable support components on both sides can move laterally, the spline rod obtains a certain amount of movement space in the longitudinal direction through the cooperation of the outer spline rod and the inner spline tube, while ensuring that the two can transmit normally. After the movable support component moves laterally, all the tow rods can still be controlled to extend and retract longitudinally.

[0014] Preferably, each of the outermost movable load-bearing components is rotatably connected to the end of one of the outer spline rods. The outer spline rod and the outermost movable load-bearing component remain stationary in the longitudinal direction. The inner spline tube is rotatably connected to the fixed load-bearing component, and both remain stationary in the longitudinal direction. The outer spline rod moves laterally with the outermost movable load-bearing component, while the inner spline tube is rotatably connected to the fixed load-bearing component, ensuring that the outer spline rods on both sides can always be drivenly connected to the inner spline tube.

[0015] Preferably, each set of support rod assemblies has a second guide rod longitudinally provided on the corresponding fixed or movable support assembly. The fixed plate is movably connected to the second guide rod, and the transmission component is a synchronous belt. The support rod drive motor drives the fixed plate to slide along the second guide rod via the synchronous belt. The second guide rod limits the sliding direction of the support rod, preventing it from getting stuck with any support assembly or telescopic assembly it might pass through, and also ensuring that the support rod can extend sufficiently longitudinally to provide support.

[0016] Preferably, a second telescopic assembly is provided between adjacent fixed plates. Both the first and second telescopic assemblies are scissor-type structures. The second telescopic assembly has several support rods arranged parallel to each other in the transverse direction, with the front ends of the support rods passing through the first telescopic assembly. The second telescopic assembly maintains longitudinal rigidity between adjacent fixed plates while allowing lateral movement with the movable support assembly. Since the front ends of the support rods pass through the first telescopic assembly, the longitudinal movement of the support rods connected to the second telescopic assembly can be positioned by the first telescopic assembly.

[0017] Preferably, the second telescopic component is connected to the corresponding support rod tail via a ball joint. This ball joint connection allows the support rod tail and the second telescopic component to maintain a certain degree of mobility, automatically adjusting the support rod angle when there is a slight deviation in the movement of the first and second telescopic components.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] By installing laterally sliding movable load-bearing components on both sides of the main frame of the fixed load-bearing component, and connecting the fixed and movable load-bearing components through a first telescopic component, the problem of existing palletizing lifting and output devices in the compartment being suspended at one end after lateral extension, causing deformation of the lateral extension component when transporting heavy objects, is solved. Since the movable load-bearing component is slidably mounted on the main frame, it receives excellent support even when it is far from the fixed load-bearing component, ensuring that the movable and fixed load-bearing components remain on the same plane. This significantly improves its load-bearing capacity and allows it to adapt to wider lateral spatial variations. The connection between the movable and fixed load-bearing components via the first telescopic component maintains their continuity, preventing excessive gaps between them. Simultaneously, the pushing actuator moves above the fixed and movable load-bearing components, allowing goods to be pushed out even after the movable load-bearing component has moved laterally.

[0041] A palletizing lifting and output device for use in a box includes a main frame 100 and a pushing component 200. The pushing component 200 includes a pushing actuator, a fixed bearing assembly 300, and a movable bearing assembly 400. Both the fixed bearing assembly 300 and the movable bearing assembly 400 are provided with a plurality of parallel rotating rollers 500, the axes of which are all arranged longitudinally. The fixed bearing assembly 300 is fixed to the main frame 100. The movable bearing assembly 400 is slidably disposed on the main frame 100 and located on both sides of the fixed bearing assembly 300. A first telescopic assembly 600 is provided between the fixed bearing assembly 300 and the movable bearing assembly 400. The moving range of the pushing actuator is located above the fixed bearing assembly 300 and the movable bearing assembly 400.

[0042] By installing laterally sliding movable load-bearing components 400 on the main frame 100 on both sides of the fixed load-bearing component 300, and connecting the fixed load-bearing component 300 and the movable load-bearing component 400 through a first telescopic component 600, the problem of existing palletizing lifting and output devices in the compartment being suspended at one end after lateral extension, causing deformation of the lateral extension component when transporting heavier objects, is solved. Since the movable load-bearing component 400 is slidably mounted on the main frame 100, it also receives good support when it is far from the fixed load-bearing component 300, ensuring that the movable load-bearing component 400 and the fixed load-bearing component 300 are always on the same plane. This significantly improves its load-bearing capacity and allows it to adapt to wider lateral spatial variations. The movable support component 400 and the fixed support component 300 are connected by the first telescopic component 600, which maintains the continuity between the movable support component 400 and the fixed support component 300 and avoids excessive gaps between them. At the same time, the push actuator moves above the fixed support component 300 and the movable support component 400, so that even if the movable support component 400 moves laterally, the goods on the movable support component 400 can be pushed out.

[0043] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

Therefore, they should not be construed as limitations on this invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0047] See Figures 1 to 12 This embodiment of the palletizing lifting and output device for use in a compartment according to the present invention includes a main frame 100, a pushing component 200, a fixed bearing component 300, a movable bearing component 400, and a supporting component 700. The main frame 100 supports the entire lifting and output device and is connected to a robotic arm or other device. The fixed bearing component 300 and the movable bearing component 400 carry the stacked items and arrange the transported stacked items in a horizontal line. The pushing component 200 pushes the stacked items in a horizontal line off the fixed bearing component 300 and the movable bearing component 400. The supporting component 700 is used to support the items when the top surface of the fixed bearing component 300 and the movable bearing component 400 is too high from the bottom surface of the compartment, to prevent the goods from falling into the compartment and being damaged due to excessive height.

[0048] The following describes the various components of the lifting output device, including but not limited to the following structures.

[0049] like Figures 1 to 3As shown, the main frame 100 has a rectangular frame structure, with its length direction being horizontal and its width direction being vertical. This allows for full utilization of the horizontal space to accommodate as many stacked boxes as possible in a row at the same time. The main frame 100, the pushing component 200, the fixed bearing component 300, and the movable bearing component 400 are essential components of the lifting and output device.

[0050] like Figure 3 , Figure 4 As shown, the main structures of the fixed bearing assembly 300 and the movable bearing assembly 400 are basically the same, both including two parallel support plates 310. The length direction of the support plates 310 is arranged laterally. Between the two plates, there are multiple rotating rollers 500 arranged in parallel longitudinal direction. Some of the rotating rollers 500 are connected to the power component to drive their rotation, while others are passively rotating rollers 500. The actively rotating rollers 500 and the passively rotating rollers 500 can be alternately arranged to reduce the number of actively rotating rollers 500, thereby reducing production costs. However, this will not hinder the lateral movement of the box falling on the fixed bearing assembly 300 or the movable bearing assembly 400.

[0051] The fixed load-bearing component 300 has movable load-bearing components 400 on both sides along the lateral direction. The fixed load-bearing component 300 is fixed in the middle of the main frame 100. The movable load-bearing components 400 on both sides along the lateral direction can be slidably connected to the main frame 100 through slide rails. The movable load-bearing components 400 can slide relative to the fixed load-bearing component 300 along the lateral direction. A first telescopic component 600 is also provided between the movable load-bearing component 400 and the fixed load-bearing component 300. The first telescopic component 600 is used to fill the gap between the movable load-bearing component 400 and the fixed load-bearing component 300 to prevent the box from falling between the fixed load-bearing component 300 and the movable load-bearing component 400. At the same time, it can ensure that the box can move from the fixed load-bearing component 300 to the movable load-bearing component 400.

[0052] To further expand the lateral adjustment range of the lifting output device, two sets of movable bearing components 400 are provided at each end of the fixed bearing component 300, namely a first movable bearing component 410 and a second movable bearing component 420. The first movable bearing component 410 is connected to the fixed bearing component 300 through a set of first telescopic components 600, and the second movable bearing component 420 is connected to the first movable bearing component 410 through another set of first telescopic components 600. By using first telescopic components 600 for all connections, the number of parts in the entire device can be reduced, which is beneficial for cost control.

[0053] like Figure 5As shown, in order to simultaneously control all movable load-bearing components 400 to move closer to or away from the fixed load-bearing component 300, a transverse drive motor 430 and a lead screw 440 driven by the transverse drive motor 430 are also fixed on the main frame 100. In order to ensure that the movable load-bearing components 400 slide smoothly on the main frame 100 without jamming, there are two lead screws 440, which are respectively close to the two ends of the movable load-bearing components 400 along the longitudinal direction. The transverse drive motor 430 drives the two lead screws 440 to rotate synchronously through a synchronous belt.

[0054] Each lead screw 440 has a first external thread 441 corresponding to the position of the first movable bearing component 410, and a nut is fixed on the first movable bearing component 410 to be threadedly connected to the first external thread 441 on the lead screw 440. Each lead screw 440 has a second external thread 442 corresponding to the position of the second movable bearing component 420, and a nut is fixed on the second movable bearing component 420 to be threadedly connected to the second external thread 442 on the lead screw 440. Furthermore, the pitch of the first thread is smaller than the pitch of the second thread, resulting in different extension and retraction speeds for the first movable bearing component 410 and the second movable bearing component 420, better adapting to different lateral length requirements of the box body. In this embodiment, the lateral drive motor 430 is located in the middle position of the main frame 100, which also ensures that the force on the lead screw 440 is more balanced when driven by the synchronous belt.

[0055] like Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, the pushing component 200 primarily pushes the boxes away from the lifting and output device after the boxes are arranged laterally on the fixed support assembly 300 and the movable support assembly 400. Specifically, the pushing component 200 includes a pushing actuator. The entire range of motion of the pushing actuator is located above the fixed support assembly 300 and the movable support assembly 400; that is, the pushing actuator needs to cover the fixed support assembly 300 and the extended movable support assembly 400 to ensure that all boxes can be pushed away.

[0056] In addition to the pushing actuator, the pushing component 200 also includes a synchronous drive motor 210. The pushing actuator includes a first push plate 220 and a second push plate 230. The first push plate 220 is located above the fixed support assembly 300. The height of the first push plate 220 from the top surface of the fixed support assembly 300 cannot be too high. When the housing enters the fixed support assembly 300, it needs to slide over the first push plate 220 first and then fall onto the fixed support assembly 300. The second push plate 230 is located above the outermost movable support assembly 400, meaning that the second push plate 230 moves laterally together with the outermost movable support assembly 400. A sliding plate 250 is provided between the first push plate 220 and the second push plate 230. The sliding plate 250 can be fixedly connected to one of the first push plate 220 or the second push plate 230 and slidably connected to the other, so that the second push plate 230 can slide relative to the first push plate 220 in the lateral direction, while the first push plate 220 and the second push plate 230 move synchronously in the longitudinal direction.

[0057] Since the first push plate 220 and the second push plate 230 need to push down the boxes arranged on the fixed support component 300 and the movable support component 400, the required driving force is relatively large. Therefore, a synchronous drive motor 210 is provided below each second push plate 230. That is, the synchronous drive motors 210 on both sides drive the push actuator at the same time, which can also ensure that the push actuator will not twist when pushing the box.

[0058] like Figure 6 , Figure 7 As shown, a first guide rod 240 is provided on the fixed bearing assembly 300 below the first push plate 220 or on the main frame 100, and the first push plate 220 is slidably mounted on the first guide rod 240. A first guide rod 240 is also provided on the outermost movable bearing assembly 400, and the synchronous drive motor 210 is also fixed on the movable bearing assembly 400. The second push plate 230 is slidably connected to the corresponding first guide rod 240 through a slider, and the synchronous drive motor 210 is connected to the second push plate 230 through a synchronous belt, thereby driving the second push plate 230 to slide longitudinally.

[0059] like Figures 8 to 10 The palletizing lifting and output device also includes a support component 700 located below the rotating roller 500, so that the box pushed away by the pushed component can fall on the support component 700. The support component 700 acts as a buffer to prevent the box from falling directly into the box and being damaged.

[0060] The support assembly 700 includes an external spline rod 710, an internal spline tube 720, a support rod drive motor 730, and several support rods 740 arranged parallel to each other in the transverse direction. Multiple support rods 740 are fixed together on the fixed plate 750 to form a support rod assembly 760. A set of support rod assemblies 760 is provided on the fixed support assembly 300 and each movable support assembly 400. This makes it much easier to control the extension of the support rods 740, as it mainly controls the extension of the support rod assembly 760, reducing the difficulty of controlling all the support rods 740 to move longitudinally.

[0061] Since the support assembly 700 does not need to overcome much resistance when moving longitudinally, it only requires one support rod drive motor 730 to drive it. However, since the movable support assembly 700 can move laterally, the drive component needs to be designed to ensure that after the support rod assembly 760 corresponding to the movable support assembly 700 moves laterally, it can also move longitudinally along with all the support rod assemblies 760. To this end, we adopt the design of an external spline rod 710 and an internal spline tube 720. The internal spline tube 720 is tubular and has an axially arranged internal spline groove on its inner wall; the spline rod is rod-shaped and has an external spline on its outer wall along the axial direction, and the external spline is adapted to the internal spline groove. Therefore, one end of the outer spline rod 710 is rotatably connected to the outermost movable load-bearing component 400, ensuring that the outer spline rod 710 can rotate along its own axis. The other end of the outer spline rod 710 is inserted into the inner spline tube 720, which is rotatably connected to the fixed load-bearing component 300 or the main frame 100, ensuring that the inner spline tube 720 can rotate along its own axis. In this way, when the movable load-bearing component 400 slides laterally, the outer spline rod 710 will move axially relative to the inner spline tube 720, but rotational transmission can still be maintained between the two.

[0062] In this way, the inner spline tube 720 is rotated by the support rod drive motor 730. The inner spline tube 720 drives the support rod assembly 760 corresponding to the fixed bearing assembly 300 to move longitudinally via the synchronous belt. At the same time, the inner spline tube 720 transmits power to the outer spline rod 710. The outer spline rod 710 then drives the support rod assembly 760 corresponding to the movable bearing assembly 400 to move longitudinally via the synchronous belt, thereby realizing the longitudinal movement of all support rod assemblies 760.

[0063] With the addition of the support component 700, the pushing component can also increase its stroke, pushing the box that falls on the support component 700 away from the support component 700, so that the box falls into the compartment.

[0064] To ensure that each set of support rod assemblies 760 can slide smoothly along the longitudinal direction, each set of support rod assemblies 760 is provided with a second guide rod 770 along the longitudinal direction on the corresponding fixed support assembly 300 or movable support assembly 400. The fixed plate 750 is slidably connected to the second guide rod 770, and the support rod drive motor drives the fixed plate 750 to slide along the second guide rod 770 through a synchronous belt.

[0065] As the movable support component 400 slides laterally away from the fixed support component 300, the first telescopic component 600 will extend to a relatively long length. To support the box located at the corresponding position of the first telescopic component 600, a second telescopic component 800 is provided between adjacent fixed plates 750. The second telescopic component 800 has the same structure as the first telescopic component 600, both being scissor-type structures. A scissor-type structure is a structure like scissors, consisting of two connecting rods rotatably connected by a pin in the middle. The two connecting rods form an X shape, and multiple sets of such connecting rods are connected in series to form a telescopic component. The second telescopic component 800 has several horizontally parallel support rods 740. The front end of the support rod 740 passes through the first telescopic component 600. Through holes can be made on the first telescopic component 600 at the positions corresponding to the support rods 740 to allow the ends of the support rods 740 to pass through. Furthermore, since there may be a certain deviation in the extension and retraction of the first telescopic component 600 and the second telescopic component 800, the second telescopic component 800 is connected to the tail of the corresponding support rod 740 via a ball head, allowing the support rod 740 at that position to have a certain degree of mobility. This prevents the support rod 740 from getting stuck in the through hole of the first telescopic component 600.

[0066] like Figure 1 , Figure 2 The initial state of the lifting and output device is as follows: after extending into the designated position inside the compartment, the horizontal drive motor 430 drives the lead screw 440 to rotate. The lead screw 440 drives the movable bearing components 400 at both ends to move, achieving a size suitable for the width inside the compartment. Boxes to be stacked are input from the middle, slide past the first push plate 220, and land on the fixed bearing component 300. The rotating roller 500 on the fixed bearing component 300 begins to rotate, conveying the boxes laterally to both sides. Finally, the boxes are arranged in a row on the fixed bearing component 300 and the movable bearing component 400. Subsequently, the synchronous drive motors 210 on both sides start, driving the second push plates 230 on both sides to move longitudinally. Simultaneously, the second push plates 230 also drive the first push plate 220 to move longitudinally. The pushing actuator pushes the rows of boxes on the fixed bearing component 300 and the movable bearing component 400 into the compartment, completing one stacking operation. Then, the lifting and output device raises the height of one box for the second layer of stacking, thus completing all stacking operations.

[0067] When the items inside the container are fragile or easily deformed, a lifting and output device with a support component 700 can be used. When the movable support component 700 moves, it synchronously drives the outer spline rod 710 relative to the inner spline tube 720. After the containers are arranged in a row on the fixed support component 300 and the movable support component 400, the synchronous drive motor 210 starts, driving the first push plate 220 and the second push plate 230 to move longitudinally. Simultaneously, the support rod drive motor 730 also starts, driving all the support rods 740 to move longitudinally and extend forward from the fixed support component 300 and the movable support component 400. The pushing component pushes the containers from the fixed support component 300 and the movable support component 400 onto the support component 700. Afterward, the pushing component can continue to push forward, pushing the containers away from the support component 700 and into the container, or the support component 700 can retract, allowing the containers on the support component to fall, completing the stacking operation.

[0068] With the above-mentioned lifting and output device, the movable support component 700, supported by the main frame 100, can support heavier boxes. Furthermore, the lateral distance adjustment of the movable support component 700 can be steplessly adjusted, with a wider range of lateral length adjustment and more applicable scenarios.

[0069] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
