Description

Technical Field

[0001] This invention relates to an in-box stacking device. Background Technology

[0002] Palletizing operations inside shipping containers are unique due to space constraints, limiting the placement of goods. The most common method is manual operation, where workers stand inside the container and neatly stack items. While suitable for small, lightweight items, manual palletizing becomes inefficient or even impossible when handling large, heavy items packaged in standard cardboard boxes. Firstly, the weight is too great for manual palletizing of heavy items; even if handling is possible, it severely strains workers' physical abilities and could even lead to workplace injuries. Secondly, manual palletizing results in uneven stress distribution on the cardboard boxes, as the contact area between hands and boxes is limited. Damaged boxes reduce efficiency or even lead to leakage. Therefore, current technologies for palletizing heavy, cardboard-packaged items inside shipping containers suffer from inefficiency and damage issues. Summary of the Invention

[0003] The technical problem to be solved by the present invention is how to efficiently and without damage stack heavy items packaged in cartons inside a box, thereby obtaining a box-stacking device.

[0004] To solve the above-mentioned technical problems, the present invention employs the following technical solution: The in-cargo palletizing device includes an inlet unit and an outlet unit. The inlet unit is equipped with a fixed base and a conveying frame. The top of the conveying frame is equipped with a conveying part. The conveying frame is movably mounted on the fixed base in a horizontal linear sliding manner. The direction of movement of the conveying frame on the fixed base is parallel to the conveying direction of the conveying part of the conveying frame. The outlet unit includes a movable lifting component and a load-output component. The movable lifting component includes a frame, a lifting frame, and a lifting component. The bottom of the frame is equipped with a traveling component. The lifting frame is movably mounted on one side of the frame via the lifting component, and the lifting component drives the lifting frame to move vertically. The frame and the conveying frame are movably connected by a guide rail. The conveying frame is movably mounted on the other side of the frame in a vertical linear sliding manner. The load-output component... The output component includes a mounting frame, a primary translation component, a secondary translation component, and a load-bearing component. The mounting frame is mounted on a lifting frame. Both the primary and secondary translation components are mounted on the mounting frame. The mounting frame has two primary translation components, each with a load-bearing component. The secondary translation component has two synchronously moving power output parts and two guide rails, each distributed on one of the two load-bearing components. The load-bearing component is mounted on the load-bearing component via the guide rails of the secondary translation component. The load-bearing component is connected to the power output part of the secondary translation component, forming a material conveying channel between the load-bearing components. The direction in which the primary translation component drives the load-bearing component is perpendicular to the direction in which the secondary translation component drives the load-bearing component. The conveying direction of the conveying part of the conveying frame and the direction in which the secondary translation component drives the load-bearing component are both parallel to the extension direction of the material conveying channel.

[0005] Palletizing operations inside containers typically occur in warehouses, which may have platforms to facilitate the transfer of goods into the containers. In this technical solution, the fixed base of the import unit is fixedly installed on the platform or a similar foundation structure, thus obtaining a basic motion reference. That is, the fixed base is fixed to the foundation structure, and its spatial position and orientation remain unchanged. The conveyor frame and the import unit are movable, so that when the vehicle docks the container at the platform, the import unit can extend into the container; in this state, the goods are transported from the outside to the inside of the container by the conveyor frame, and after entering the container, the load output component lifts and translates the goods, causing them to enter the predetermined placement position. The mobile lifting component provides movement functionality to the load output component and the conveyor frame; it also provides lifting and translation functionality to the load output component. This lifting and translation functionality includes the vertical reciprocating motion of the mounting frame on the chassis, allowing the load-bearing component to change its spatial position (height) vertically. The load-bearing component can reciprocate vertically on the chassis. A first-level translation component drives the load-bearing component to reciprocate horizontally, allowing it to change its spatial position horizontally, but this position change is within the inner edge of the mounting frame. A second-level translation component drives the load-bearing component to reciprocate horizontally, allowing it to protrude beyond one side of the mounting frame (i.e., beyond its edge). Labeling the vertical movement of the load-bearing component on the chassis as Y, the horizontal movement of the load-bearing component driven by the first-level translation component as X, and the horizontal movement of the load-bearing component driven by the second-level translation component as Z, it is easy to see that the directions of movement X, Y, and Z are perpendicular to each other, thus establishing that the load-bearing component can move in a three-dimensional area. Therefore, the material conveying channel is positioned in different spatial locations along with the movement of the load-bearing components. Conveying frames for the conveying parts and load-bearing components capable of three-dimensional movement are arranged on both sides of the frame. Once the load-bearing components align with the conveying parts, items entering the compartment can enter the material conveying channel. Subsequently, the load-bearing components can move the items until they reach the target position, i.e., the stacking position. With this technical solution, items only need to be placed on the conveying parts; after entering the material conveying channel, they are lifted to the target position, i.e., the stacking position. Finally, workers push the items out of the conveying channel, completely eliminating manual handling and lifting of items. When handling cardboard boxes, it is necessary to ensure that the boxes are evenly stressed to avoid damage. In this technical solution, the material conveying channel is constructed using two load-bearing components. The conveying channel is a closed structure that provides significant support for the items and can accommodate longer dimensions of the items in practical applications. This results in a large and evenly distributed stress area, preventing surface damage to the items.

[0006] Two primary translational components each drive the movement of a load-bearing component; that is, each load-bearing component requires an independent primary translational component. The primary translational components are not directly connected to the load-bearing components, but rather connected through the power output section of the secondary translational components. In other words, the primary translational components moving the load-bearing components simultaneously drive the power output section of the secondary translational components. The secondary translational components can also drive the load-bearing components, but the direction of movement of the load-bearing components driven by the primary translational components intersects with the direction driven by the secondary translational components, and the direction of movement driven by the primary translational components is perpendicular to the direction of movement driven by the secondary translational components.

[0007] The primary translation component drives the load-bearing components to move in two ways: synchronous movement in the same direction and synchronous movement in opposite directions. Synchronous movement in the same direction occurs when the two load-bearing components move at a fixed distance, which can be in an unloaded or loaded state. Synchronous movement in opposite directions occurs when the load-bearing components open (increasing the distance between them) or close (decreasing the distance between them), thus changing the size of the material conveying channel. Since the primary translation component is integrated into the load output component, it is easy to understand that the width of the material conveying channel can be adjusted online according to the size of the item, making it suitable for handling items of various sizes.

[0008] The secondary translation component drives the load-bearing member's movement only through synchronous movement in the same direction. This provides an additional horizontal displacement to the load-bearing member on top of the displacement provided by the primary translation component, thus increasing the horizontal displacement range of the item. The translation operation provided by the secondary translation component plays a significant role in the stacking of items within the container. After the item reaches the perimeter of the predetermined area, it can be moved closer to or into the target position through the translation operation provided by the secondary translation component. The work that the secondary translation component can perform is extremely important in container stacking scenarios, which can greatly help workers complete their work, reduce labor intensity, and improve work efficiency.

[0009] To further expand the horizontal movement range of the load-bearing component, the movable lifting mechanism also includes a three-stage translation component. The mounting frame is movably mounted on the lifting frame via the three-stage translation component, and the three-stage translation component drives the mounting frame to move horizontally. The direction of the movement of the mounting frame driven by the three-stage translation component is parallel to the direction of the movement of the load-bearing component driven by the first-stage translation component. The three-stage translation component can drive the mounting frame to perform translational movement. Marking the horizontal movement of the load-bearing component driven by the three-stage translation component as X', it can be seen that movement X' is parallel to movement X. In this way, the load-bearing component achieves the maximum displacement of the overall structure.

[0010] The chassis can move on the platform, but considering the wear and tear on the ground after long-term use and the ground's own load-bearing capacity, in order to prevent ground deformation and cracking, this technical solution includes a structure to protect the ground and improve the ease of chassis movement. Specifically, the output unit also includes a guide support component, which has a working surface located directly below the walking assembly. The working surface includes a guide ramp and a horizontal support surface, which are distributed along the conveying direction parallel to the conveying section of the conveying frame. One end of the guide ramp is connected to the horizontal support surface, and the vertical height of one end of the guide ramp is higher than the vertical height of the other end of the guide ramp. The vertical height of the conveying section is higher than the vertical height of the horizontal support surface. The chassis is movably connected to the guide support component by supporting the walking assembly through the working surface.

[0011] The walking assembly receives guidance and support from the guiding support components. The guidance function stems from the highly visible working surface of the guiding support components relative to the ground. Whether operating under manual or automatic guidance, the walking assembly receives visual alert from this working surface, thereby regulating or limiting its movement range. For example, when manually guiding the walking assembly, if the operator notices that the assembly is about to cross the working surface or has already crossed it, immediate correction can be made to restore the assembly to a position above the working surface. During automatic guidance, corrections can be made based on the vision system. The support function is entirely achieved through the support process; that is, it is obtained on the premise that the guidance function is effective.

[0012] When the chassis moves on the working surface, the entire internal stacking device is in a telescopic state. In the initial state, the chassis is located on the horizontal support surface, and the stacking between the conveyor frame and the fixed base is the closest. In the working state, the chassis will move towards the location of the guide ramp and move towards the inside of the container in front of the platform, and finally detach from the guide support component after passing the guide ramp.

[0013] The horizontal support surface functions when the chassis returns to its initial state. The guide ramp, acting as a transition structure between the horizontal support surface and the interior floor, functions as the chassis moves inward, i.e., the conveyor frame extends outward. Since the guide ramp is inclined relative to both the horizontal plane and the horizontal support surface, the interior floor height must be lower than the horizontal support surface height. To prevent the guide support components from forming a cutting edge or shearing structure below the guide ramp that could affect safe production, the other end of the guide ramp extends vertically. This vertical extension of the guide ramp prevents vehicle components from extending below the guide ramp or the guide ramp portion of the guide support components from embedding into the vehicle interior, thereby eliminating potential safety hazards during production operations.

[0014] In this technical solution, the traveling assembly includes two sets of rollers distributed in a direction parallel to the conveying direction of the conveying section. The frame is movably connected to the guide support component by supporting the rollers through the working surface. The departure angle of the roller closest to the conveying frame on the frame is greater than the inclination angle of the guide ramp relative to the horizontal plane. The length of the horizontal support surface is greater than the center distance between the two sets of rollers. The rollers at the bottom of the frame can be selected from any rolling components or parts that facilitate the movement of the frame and reduce friction. In this technical solution, there are at least two sets of rollers, and the two sets of rollers are distributed one after the other in a direction parallel to the conveying direction of the conveying section, separated by a certain distance. The departure angle of the roller closest to the conveying frame on the frame has specific requirements. This design ensures that when the frame is supported by the horizontal support surface, the guide ramp, and the floor of the carriage, at least one roller is always supported, i.e., at least one roller is always in contact with the ground, thereby ensuring that the frame can maintain a flexible movement state during movement.

[0015] In this technical solution, the primary translation component also includes a guide rod and a power assembly I. The power assembly I has a power output section. The guide rod is fixedly mounted on the mounting frame, and the load is movably mounted on the guide rod in a sliding manner. The power output section of the power assembly I is connected to the load, and the power assembly I drives the load to move. Because the load-bearing function and the adjustment and driving function are divided into two structures, the guide rod is responsible for the load-bearing operation, and the power assembly I is responsible for the adjustment and driving operation. The load-bearing capacity of the guide rod can be relatively high based on existing industrial conditions. After the functional division, the structural scheme of the power assembly I can be selected from electric cylinders, pneumatic cylinders, hydraulic cylinders, and synchronous mechanisms. Therefore, the primary translation component under this structure has significant load-bearing capacity and compatibility.

[0016] Based on the normal operating conditions of the load-carrying output component, it can be observed that when an item detaches from the side of the component, its center of gravity shifts significantly. This severe shift alters the stress structure of critical connection points and increases the risk of mechanical fatigue. To maintain the center of gravity of the load-carrying output component within a reasonable range during operation, the power assembly I in this machine's technical solution includes a synchronous belt, pulleys, a drive shaft, a motor, and a reducer. The motor is connected to the reducer and mounted on the mounting frame via the reducer. The synchronous belt is mounted on the drive shaft via pulleys. The drive shaft is movably mounted on the mounting frame and connected to the reducer. The synchronous belt is fixedly connected to the load, and the extension direction of the drive shaft is parallel to the extension direction of the material conveying channel. The straight section of the synchronous belt, after unfolding, serves as the power output section of power assembly I and can be positioned for easy connection to the load. Other components that generate and transmit power, having significant weight, can be positioned on one side of the mounting frame. This ensures that the center of gravity shift of the load-carrying output component during operation does not exceed the upper limit and remains within a reasonable range. Furthermore, the connection between the drive shaft and the reducer can be based on a direct connection or an indirect connection, depending on the availability of space. If space is sufficient, the drive shaft is directly connected to the reducer; if space is limited, an auxiliary shaft can be added between the drive shaft and the reducer to establish a connection. Once the connection is established, the drive shaft will inevitably rotate under the drive of the motor. This technical solution includes two primary translation components, thus requiring two power components I. If each primary translation component uses an independent mechanical structure, it would necessitate two sets of identical parts, resulting in a significant weight for the entire load-bearing output component. To avoid excessive weight for the load-bearing output component, this technical solution employs a transmission structure with shared parts for the two primary translation components. Specifically, the drive shaft and pulley of power component I in any one primary translation component are fixedly connected, while the drive shaft of power component I in any one primary translation component is movably connected to the pulley of the other power component I.

[0017] The secondary translation component consists of one unit, but has two power output points corresponding to the primary translation component. These power output points can be constructed using an electric cylinder, pneumatic cylinder, hydraulic cylinder, or a synchronization mechanism. In this technical solution, the power output points of the secondary translation component are constructed using a synchronization mechanism, primarily to maintain the center of gravity of the load-bearing component within a reasonable range during operation. The secondary translation component also includes a power assembly II, which comprises a synchronous belt, pulleys, a splined shaft, a motor, and a reducer. The motor is connected to the reducer and is mounted on a mounting frame via the reducer. The splined shaft is movably mounted on the mounting frame. The synchronous belt is mounted on the load-bearing component via pulleys, one of which is movably connected to the splined shaft. The synchronous belt is fixedly connected to the load-bearing component, and the splined shaft is connected to the reducer.

[0018] A smaller gap between the two load-bearing components expands the applicability of the in-box stacking device. The load-bearing components utilize a three-dimensional structure formed by bending sheet metal. Each component has an L-shaped bearing portion with a clamping surface and a loading surface. The clamping surfaces of the two load-bearing components face each other, while their loading surfaces are vertically separated. The two load-bearing components are arranged in opposite directions, allowing their loading surfaces to overlap when close together, thus achieving a smaller gap and reducing the width of the conveying channel. To facilitate the ejection of items from the side of the loading output component, the load-bearing components have a guide bevel at the loading surface. The angle between the extension direction of the guide bevel and the extension direction of the conveying channel is acute. This design ensures that items are not subjected to resistance from the forward direction during ejection, facilitating easy ejection.

[0019] The items are placed in the conveying channel and need to be removed from the channel after reaching the target position. The aforementioned method requires manual pushing to remove the items, which offers high flexibility and allows for ideal stacking results, especially when the items are not properly aligned with the target position; adjustments can be made manually. However, this method still imposes a certain level of labor intensity on workers. To further reduce this labor intensity, this invention provides a mechanical auxiliary structure for the item removal stage. Specifically, the load output component includes a one-way pushing component, which is installed on the load of one of the primary translation components. The one-way pushing component includes a power assembly III and a linear pushing unit. The linear pushing unit includes a guide plate, a slide table, and a push plate. The guide plate is fixedly installed on one of the loads. The slide table is movably installed on the load in a linear sliding manner. The movement direction of the slide table on the load is parallel to the extension direction of the material conveying channel. The push plate is movably installed on the slide table and can swing on the slide table. The guide plate is provided with a guide groove. One end of the push plate is embedded in the guide groove. The guide groove is provided with a pushing and holding part and a lifting and guiding part. The pushing and holding part and the lifting and guiding part are connected. The pushing and holding part is straight and its extension direction is parallel to the extension direction of the material conveying channel. The lifting and guiding part is offset from the extension direction of the pushing and holding part. The power assembly III is provided with a power output part. The power output part is connected to the slide table and the power assembly III drives the push plate to move. The movement range of the other end of the push plate intersects with the material conveying channel. The pusher plate of the unidirectional pushing component can maintain different spatial postures at different travel positions. Within the conveying channel, the pusher plate maintains a vertical posture, and after leaving the conveying channel, it maintains a horizontal posture. The posture change of the pusher plate relies on the design of a linear cam structure; that is, the entire linear pushing unit is a linear cam structure, and the movement of the pusher plate is synchronized with its posture change. The flexible characteristics of the pusher plate can be well coordinated with the operation stage of the product entering the conveying channel. When the product moves towards the target position and leaves the conveying channel, there is no need for manual pushing of the item. The pusher plate only needs to restrain the item, and at the same time, the load-bearing component moves away from the target position. In this way, the pusher plate moves relative to the load-bearing component within the conveying channel, and finally the item leaves the conveying channel. The structural scheme of the power component III can also be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0020] The telescopic feature of the in-box palletizing device is a specific manifestation of its working range. To expand the telescopic range of the in-box palletizing device, this technical solution includes an extension structure and a power component between the conveying frame and the fixed base. Specifically, the inlet unit also includes an auxiliary frame, power component IV, and power component V. The conveying frame and the auxiliary frame are movably connected via guide rails. The conveying frame is movably mounted on the auxiliary frame in a horizontal linear sliding manner. The auxiliary frame and the fixed base are movably connected via guide rails. The auxiliary frame is movably mounted on the fixed base in a horizontal linear sliding manner. Power component IV is mounted on the fixed base and has a power output part. The power output part of power component IV is connected to the auxiliary frame, and power component IV drives the auxiliary frame to move on the fixed base. Power component V is mounted on the auxiliary frame and has a power output part. The power output part of power component V is connected to the conveying frame, and power component V drives the conveying frame to move on the auxiliary frame. Thanks to the extension of the auxiliary frame, the range of motion of the output unit is increased, thus enabling the in-container stacking device to handle containers of greater length.

[0021] The present invention adopts the above-mentioned technical solution: the in-container stacking device can extend into the container and replace manual labor to complete the handling operations of transporting goods from the outside of the container to the inside of the container and the lifting operations of stacking goods inside the container. This not only reduces labor intensity and improves work efficiency, but also avoids damage to goods and keeps the surface of the goods intact. Attached Figure Description

Figure III . Detailed Implementation

[0033] like Figure 1 , 2 As shown in 3, 4, 5, 6, 7, 8, 9, and 10, this is the first embodiment of the present invention.

[0034] Warehouses are major transshipment points for goods, with frequent turnover. To facilitate loading and unloading, warehouses are generally equipped with platforms. In this embodiment, the in-cargo stacking device is installed on the warehouse platform.

[0035] The in-cargo palletizing device consists of two main units: an inlet unit 1 and an outlet unit 2. The inlet unit 1 is responsible for conveying items to the outlet unit 2 and maintaining the connection between the conveying path and the outlet unit 2. The outlet unit 2 is responsible for receiving items from the inlet unit 1 and placing the items at the target location.

[0036] The import unit 1 includes a fixed base 3, a conveying frame 4, an auxiliary frame 5, a power component IV 6, and a power component V 7.

[0037] The fixed base 3 is made of welded metal and is fixed to the platform, thus the fixed base 3 is firmly connected to the ground.

[0038] The auxiliary frame 5 is also welded from metal and has a flat rectangular shape. The auxiliary frame 5 is mounted on the fixed base 3, and the two are movably connected by a guide rail, which includes a linear slide rail and a guide sleeve. The linear slide rail is fixedly mounted horizontally inside the fixed base 3, and the guide sleeve is fixedly mounted on the outside of the auxiliary frame 5. The fixed base 3 and the auxiliary frame 5 are slidably connected by the linear slide rail embedded in the guide sleeve, allowing the auxiliary frame 5 to slide linearly horizontally on the fixed base 3. The fixed base 3 has an opening on one side to ensure that the auxiliary frame 5 extends outward from the side of the conveyor frame 4 when sliding on the fixed base 3.

[0039] Power assembly IV6 includes a motor, a reducer, a synchronous belt, and pulleys. The synchronous belt is mounted on the fixed base 3 via the pulleys. The motor is connected to the reducer and is also mounted on the fixed base 3 via the reducer. One of the pulleys is connected to the output shaft of the reducer. The synchronous belt unfolds on the pulley, forming an arc-shaped structure at both ends and a straight section in the middle. The motor drives the synchronous belt when started. The straight section in the middle of the unfolded synchronous belt serves as the power output section of power assembly IV6. The power output section of power assembly IV6 is connected to the auxiliary frame 5, and power assembly IV6 drives the auxiliary frame 5 to move on the fixed base 3.

[0040] The main body of the conveying frame 4 is welded from metal. The conveying frame 4 is mounted on the auxiliary frame 5, and the two parts are movably connected by a guide rail. The guide rail includes a linear slide rail and a guide sleeve. The linear slide rail is fixedly mounted horizontally on the top of the auxiliary frame 5, and the guide sleeve is fixedly mounted on the bottom of the conveying frame 4. The conveying frame 4 and the auxiliary frame 5 are slidably connected by the linear slide rail embedded in the guide sleeve. In this way, the conveying frame 4 can slide linearly in the horizontal direction on the auxiliary frame 5.

[0041] Power assembly V7 includes a motor, a reducer, a lead screw, and a lead screw sleeve. The lead screw is mounted on the auxiliary frame 5. The motor is connected to the reducer and is also mounted on the auxiliary frame 5 via the reducer. The output shaft of the reducer is connected to the lead screw. The lead screw sleeve, as the power output part of power assembly V7, is fixed to the conveyor frame 4. The lead screw sleeve meshes with the lead screw. When the motor starts, it can directly drive the conveyor frame 4 to move on the auxiliary frame 5 via the lead screw. Therefore, the power output part of power assembly V7 is connected to the conveyor frame 4, and power assembly V7 drives the conveyor frame 4 to move on the auxiliary frame 5.

[0042] The auxiliary frame 5 on the import unit 1 can slide on the fixed base 3, and the conveying frame 4 can slide on the auxiliary frame 5. The movement of the auxiliary frame 5 and the conveying frame 4 can be controlled by electrical components, and the movement directions of the two are the same, thus the import unit 1 has a telescopic feature.

[0043] The top of the conveyor frame 4 is equipped with a conveyor belt, a motor, and a reducer to drive the conveyor belt. The conveyor belt is mounted on the conveyor frame 4 via rollers, and the motor is mounted on the conveyor frame 4 via a reducer. The output shaft of the motor reducer is connected to one of the rollers. After the motor starts, it can drive the conveyor belt to run. The operation of the conveyor belt provides a conveying section 44 for conveying operations. The conveying direction of the conveying section 44 is parallel to the sliding direction of the conveyor frame on the auxiliary frame 5 and parallel to the sliding direction of the auxiliary frame 5 on the fixed base 3.

[0044] Output unit 2 consists of a movable lifting component 8, a loading output component 9, and a guide support component 10. The movable lifting component 8 is movably connected to the conveyor frame 4 and is located at one end of the inlet unit 1. After the inlet unit 1 performs a telescopic movement, the movable lifting component 8 is pushed or pulled and moves synchronously with the conveyor frame 4. The loading output component 9 is installed on the movable lifting component 8 and obtains changes in height position by using the movable lifting component 8 as a support base.

[0045] The mobile lifting component 8 includes a frame 11, a lifting frame 12, a lifting component 13, and a three-stage translation component 14.

[0046] The bottom of the frame 11 is equipped with a traveling assembly 15, which is a non-powered mechanism and includes two sets of rollers, with two rollers in each set. The number of sets and the quantity of rollers in each set can be set according to actual needs. In this embodiment, two sets of rollers with two rollers in each set are used as an example to illustrate this technical feature. The two sets of rollers are arranged separately in the direction of conveying perpendicular to the conveying part 44, and each set of rollers is distributed in the direction parallel to the conveying direction of the conveying part 44, that is, in the direction of linear reciprocating motion of the conveying frame 4 on the auxiliary frame 5. Two of these four rollers are farther away from the conveying frame 4, and the other two are closer to the conveying frame 4. The four rollers are arranged in a matrix at the bottom of the frame 11.

[0047] The frame 11 is a gantry frame structure. The frame 11 is positioned at one end of the conveyor frame 4 and is movably connected to the conveyor frame 4 via guide rails. The guide rails also include linear slide rails and guide sleeves. The linear slide rails are vertically mounted on the conveyor frame 4, and the guide sleeves are fixedly mounted on the frame 11. The frame 11 can perform linear reciprocating motion relative to the conveyor frame 4 in the vertical direction. The frame 11 has a smooth, hollow structure in the middle, which is located precisely in the conveying direction of the conveying section 44 of the conveyor frame 4.

[0048] The lifting frame 12 is a frame structure, movably mounted on one side of the chassis 11 via a lifting component 13, which drives the lifting frame 12 to move vertically. The lifting component 13 includes a guide rail, a lead screw, a lead screw sleeve, a motor, and a reducer. The motor and reducer are combined and mounted on the chassis 11. The lead screw is movably mounted vertically on the chassis 11, and the reducer is connected to the lead screw via a synchronous belt. The guide rail includes a linear slide rail and a sliding sleeve. The linear slide rail is fixedly mounted vertically on the chassis 11, and the sliding sleeve is fixedly mounted on the lifting frame 12. The lifting frame 12 is movably connected to the chassis 11 via the linear slide rail and the sliding sleeve. The lead screw sleeve is fixed to the lifting frame 12, and the lead screw and the lead screw sleeve are threaded together. The rotation of the lead screw causes the lifting frame 12 to move vertically on the chassis 11, thereby driving the lifting frame 12 to move vertically and achieve the lifting effect.

[0049] The lifting frame 12 and the conveying frame 4 are located on both sides of the frame 11, that is, the lifting frame 12 is located on one side of the frame 11 and the conveying frame 4 is located on the other side of the frame 11. The lifting frame 12 can make vertical linear movements on the frame 11, and the conveying frame 4 can also make vertical relative linear movements with the frame 11.

[0050] The guide support component 10 is a rigid metal part, fixed to the platform, and like the fixed base 3, it is firmly connected to the ground. The guide support component 10 is located below the chassis 11 and is in direct contact with the running gear 15; its function is to support the chassis 11. The guide support component 10 has a working surface 16 for contacting the rollers, which includes a guide ramp 17 and a horizontal support surface 18. The horizontal support surface 18 is a horizontal surface structure with a length greater than the center distance between the two sets of rollers. The guide ramp 17 is a planar structure with a tilted spatial orientation. The vertical height of the conveying part 44 is higher than the vertical height of the horizontal support surface 18. The horizontal support surface 18 and the guide ramp 17 are distributed sequentially along a direction parallel to the conveying direction of the conveying part 44. One end of the horizontal support surface 18 is connected to one end of the guide ramp 17. The vertical height of the end of the guide ramp 17 connected to the horizontal support surface 18 is higher than the vertical height of the other end of the guide ramp 17. The other end of the guide ramp 17 has an extension, which is a vertical planar structure and is the lowest point on the guide ramp 17.

[0051] The frame 11 is unrestrained in the vertical direction, so under its own weight, one or two rollers in each group always remain in contact with the working surface 16. The guide support component 10 provides support to the frame 11, so the frame 11 is movably connected to the guide support component 10 by supporting the rollers through the working surface 16. To ensure a smooth transition of the rollers between the guide ramp 17 and the horizontal support surface 18, the departure angle of the roller closest to the conveyor frame 4 on the frame 11 is greater than the inclination angle of the guide ramp 17 relative to the horizontal plane. This avoids interference between the frame 11 and the guide support component 10 at the guide ramp 17. In the initial state, the conveyor frame 4 is located above the auxiliary frame 5, the auxiliary frame 5 is located inside the fixed base 3, and the guide unit 1 is in a retracted state; the frame 11 is linked with the conveyor frame 4, so the entire frame 11 is placed above the horizontal support surface 18, and all four rollers are connected to the horizontal support surface 18. When the conveying frame 4 translates relative to the auxiliary frame 5 and the auxiliary frame 5 translates relative to the fixed base 3, the guide unit 1 is in an extended state. Then the frame 11 is pushed by the conveying frame 4, and the rollers move along the working surface 16. Therefore, the frame 11 is movably connected to the guide support component 10 by supporting the rollers, i.e., the traveling component 15, through the working surface 16.

[0052] The cargo output component 9 includes a mounting frame 19, a primary translation component 21, a secondary translation component 22, a one-way pushing component 23, and a load-bearing component 20. The mounting frame 19 serves as the mounting base for the cargo output component 9, and the primary translation component 21, the secondary translation component 22, the one-way pushing component 23, and the load-bearing component 20 are all mounted on the mounting frame 19.

[0053] Mounting frame 19 is movably mounted on lifting frame 12 via a three-stage translation component 14, which drives mounting frame 19 to move horizontally. The three-stage translation component 14 includes a guide rail, a timing belt, pulleys, a motor, and a reducer. The motor and reducer are mounted together on lifting frame 12. The timing belt is mounted on lifting frame 12 via pulleys, with one pulley mounted on the reducer. After installation, the timing belt unfolds to form a structure with arc-shaped ends and a straight middle section. The guide rail includes a linear slide rail and a sliding sleeve. The linear slide rail is fixedly mounted horizontally on lifting frame 12, and the sliding sleeve is fixedly mounted on mounting frame 19. Mounting frame 19 is movably connected to lifting frame 12 via the linear slide rail and the sliding sleeve. The straight section of the timing belt serves as the power output section of the three-stage translation component 14 and is fixedly connected to mounting frame 19. The motor drives the timing belt to rotate, causing mounting frame 19 to move, which in turn drives mounting frame 19 to move horizontally via the three-stage translation component 14. Mounting frame 19 achieves left-right translation along the entire frame 11.

[0054] The mounting frame 19 is provided with two primary translation components 21. Each primary translation component 21 includes a load-bearing component 24, a guide rod 25, and a power assembly I 26.

[0055] Power assembly I 26 provides the power to drive the movement of the load 24. Power assembly I 26 includes a synchronous belt, pulleys, drive shaft 27, auxiliary shaft 28, motor, and reducer. The motor is connected to the reducer and is mounted on the mounting frame 19 via the reducer. Both the motor and the reducer are located on the mounting frame 19, and the end connected to the lifting frame 12 is located on one side of the mounting frame 19. The auxiliary shaft 28 is longer than the drive shaft 27. They are both movably mounted on the mounting frame 19 and are parallel to each other. One end of the auxiliary shaft 28 is fixedly connected to the output shaft of the reducer via a drive belt. The auxiliary shaft 28 has a pulley, and the drive shaft 27 has a pulley. The auxiliary shaft 28 and the drive shaft 27 are connected by a drive belt mounted on the pulleys. When the auxiliary shaft 28 rotates, the drive shaft 27 rotates synchronously. Thus, the drive shaft 27 is indirectly connected to the reducer. The load output component 9 has two primary translation components 21, which means there are two power assemblies I 26, and therefore two drive shafts 27. The synchronous belt is mounted on the drive shaft 27 via pulleys. Two pulleys are required for the synchronous belt to unfold, forming a structure with arc-shaped ends and a straight middle section. The two drive shafts 27 are located on both sides of the mounting frame 19. The drive shaft 27 of any one of the power components I 26 of the first-stage translation component 21 is fixedly connected to the pulley via a key. The drive shaft 27 of any one of the power components I 26 is movably connected to the pulley of the other power component I 26 via bearings. This allows the pulleys to share the drive shaft 27 of the other power component I 26, thus reasonably reducing the number of components in the entire load-carrying output component 9. The two power components I 26 can operate independently; starting the motor of either power component I 26 and driving the synchronous belt will not affect the movement of the synchronous belt in the other power component I 26.

[0056] The guide rod 25 is fixedly mounted on the mounting frame 19, and is perpendicular to the drive shaft 27. The load 24 is slidably mounted on the guide rod 25, and can slide freely on the guide rod 25 in a direction perpendicular to the center line of the drive shaft 27. The straight section of the synchronous belt on the power assembly I 26 is fixedly connected to the load 24, and the straight section of the synchronous belt on the power assembly I 26 serves as the power output section of the power assembly I 26 to provide power to the load 24. When the synchronous belt rotates, it drives the load 24 to move along the guide rod 25. Since the power assemblies I 26 on the two primary translation components 21 can move independently, the loads 24 on the two primary translation components 21 can move synchronously towards each other, move synchronously in opposite directions, move synchronously in the same direction, move asynchronously towards each other, move asynchronously in opposite directions, or move asynchronously in the same direction. The load 24 has a very high degree of freedom of movement.

[0057] The secondary translation component 22 includes a guide rail and a power assembly II 29.

[0058] The power assembly II 29 includes a synchronous belt, pulleys, a splined shaft 30, a motor, and a reducer. The motor is connected to the reducer and is mounted on the mounting frame 19 via the reducer. The splined shaft 30 is movably mounted on the mounting frame 19, and is parallel to the guide rod 25 of the first-stage translation component 21. The splined shaft 30 is connected to the reducer via a transmission belt. The power assembly II 29 has two synchronous belts, which are respectively arranged on two carriers 24. Pulleys are mounted on the carriers 24, and the synchronous belts are mounted on the pulleys. Each synchronous belt is unfolded to form an arc-shaped structure at both ends and a straight section in the middle. One pulley of the synchronous belt on each carrier 24, used for mounting the power assembly II 29, is movably connected to the splined shaft 30. This pulley has a transmission key inside, corresponding to the transmission key on the splined shaft 30. The pulley meshes with the splined shaft 30, allowing it to translate along the centerline of the splined shaft 30 and move synchronously with the splined shaft 30 in a circumferential direction around the centerline. The straight section formed by the unfolded synchronous belt is perpendicular to the guide rod 25 of the first-stage translation component 21. The straight section of each synchronous belt serves as the load output component 9 of the power assembly II 29. Since the power assembly II 29 has two synchronous belts, and both synchronous belts transmit power based on the same spline shaft 30 and operate synchronously with each other, the power assembly II 29 has two power output components that move synchronously in the same direction.

[0059] The secondary translation component 22 includes two guide rails, each consisting of a linear slide rail and a sliding sleeve. The linear slide rails are respectively mounted on two load members 24, and are perpendicular to the guide rod 25 of the primary translation component 21. A load member 20 is mounted on each load member 24, and a sliding sleeve is installed on the load member 20. The load member 20 is attached to the linear slide rail via the sliding sleeve and thus mounted on the load member 24. After installation, the load member 20 can slide on the load member 24, and the direction of this sliding motion is perpendicular to the center line of the guide rod 25 of the primary translation component 21. The straight section of the synchronous belt of the power assembly II 29, i.e., the load output component 9, is fixedly connected to the load member 20, so that the two load members 20 can perform linear motion under the drive of the secondary translation component 22. The load-bearing component 20 is mounted on the load-bearing component 24, which is part of the first-level translation component 21. Therefore, the load-bearing component 20 is also driven by the first-level translation component 21 and moves in a straight line after being driven. The direction in which the first-level translation component 21 drives the load-bearing component 20 is perpendicular to the direction in which the second-level translation component 22 drives the load-bearing component 20.

[0060] The load-bearing component 20 is formed by bending a sheet metal plate. It has an L-shaped load-bearing portion 31. The inner side of the load-bearing portion 31 has a clamping surface 32 and a loading surface 33. Both the clamping surface 32 and the loading surface 33 are planar structures. In the working state, the clamping surface 32 is in a vertical plane and the loading surface 33 is in a horizontal plane. One load-bearing component 20 is installed on one loading component 24, and another load-bearing component 20 is installed on another loading component 24. The clamping surfaces 32 of the load-bearing portions 31 of the two load-bearing components 20 face each other and are parallel to each other. The loading surfaces 33 of the load-bearing portions 31 of the two load-bearing components 20 are separated in the vertical direction and are parallel to each other. A material conveying channel that is open at both ends and closed in the middle is naturally formed between the two load-bearing components 20. The degree of closure of the middle part of the material conveying channel is related to the degree of overlap of the load-bearing portions 31 of the two load-bearing components 20. The greater the overlap, the higher the degree of closure, and vice versa. The extension direction of the material conveying channel is parallel to the extension direction of the drive shaft 27, which is also parallel to the direction in which the secondary translation component 22 drives the load-bearing component 20 to move, and the conveying direction of the conveying part 44 of the conveying frame 4 is also parallel to the extension direction of the material conveying channel. The load-bearing component 20 is linked with the load-bearing component 24. Therefore, only when the primary translation component 21 drives the load-bearing component 24 to move, the load-bearing components 20 will exhibit an open state with increased spacing, a closed state with decreased spacing, and a lateral translation state in which the spacing between the two load-bearing components 20 remains unchanged and moves to one side. Only when the secondary translation component 22 drives the load-bearing component 20 to move, the load-bearing components 20 will exhibit a longitudinal translation state in which the spacing between the two load-bearing components 20 remains unchanged and moves to one side. Therefore, the distance between the load-bearing components 20 is adjustable, and the initial position of the load-bearing components 20 on the mounting frame 19 is adjustable, which makes the load-bearing output component 9 highly flexible and applicable.

[0061] The load-bearing component 20 has a guide slope 34 at the location of the loading surface 33, and the extension directions of the guide slopes 34 of the two load-bearing components 20 intersect at opposite angles. The extension direction of any one of the guide slopes 34 intersects the extension direction of the conveying channel at an acute angle. In the conveying direction of the conveying part 44 of the conveying frame 4, the guide slope 34 gradually approaches the clamping surface 32 of the load-bearing part 31. This design helps to reduce the resistance encountered when the item leaves the conveying channel.

[0062] The directions in which the first-level translation component 21 drives the load-bearing component 20, the second-level translation component 22 drives the load-bearing component 20, the third-level translation component 14 drives the mounting frame 19, the extension direction of the material conveying channel, and the conveying direction of the conveying part 44 of the conveying frame 4 are all horizontal. The direction in which the first-level translation component 21 drives the load-bearing component 20 is parallel to the direction in which the third-level translation component 14 drives the mounting frame 19. The direction in which the second-level translation component 22 drives the load-bearing component 20 is parallel to the extension direction of the material conveying channel and the conveying direction of the conveying part 44 of the conveying frame 4. The direction in which the first-level translation component 21 drives the load-bearing component 20 is perpendicular to the extension direction of the material conveying channel. The lifting component 13 drives the lifting frame 12 to move in a vertical direction, which is perpendicular to the direction in which the first-level translation component 21 drives the load-bearing component 20, the second-level translation component 22 drives the load-bearing component 20, the third-level translation component 14 drives the mounting frame 19, the extension direction of the material conveying channel, and the conveying direction of the conveying part 44 of the conveying frame 4.

[0063] The conveying direction of the conveying section 44 of the conveying frame 4 is used as a reference. The load-bearing component 20 only performs left-right translational movement when the first-level translation component 21 drives the load-bearing component 20 to move synchronously and in the same direction. The load-bearing component 20 also performs left-right translational movement only when the third-level translation component 14 drives the mounting frame 19. The load-bearing component 20 only performs forward-backward translational movement when the second-level translation component 22 drives the load-bearing component 20. The load-bearing component 20 only performs lifting and lowering movements when the lifting component 13 drives the lifting frame 12.

[0064] The unidirectional pushing component 23 includes a power assembly Ⅲ 42 and a linear pushing unit, wherein the linear pushing unit includes a guide plate 35, a slide table 36, and a push plate 37. The guide plate 35 is fixedly mounted on the load 24 of one of the primary translation components 21. The slide table 36 is slidably mounted on the load 24 and can perform linear sliding motion on the load 24. The direction of movement of the slide table 36 on the load 24 is parallel to the extension direction of the conveying channel. The push plate 37 is movably mounted on the slide table 36 and can swing on the slide table 36. The joint between the push plate 37 and the slide table 36 is biased towards one end of the push plate 37, which makes the length of the push plate 37 on the two sides of the fulcrum obtained based on the slide table 36 different, that is, one side is longer and the other side is shorter. The guide plate 35 is provided with a guide groove 38, which consists of a push-holding part 39 and a lifting guide part 40. The push-holding part 39 is straight and its extension direction is parallel to the extension direction of the material conveying channel. The push-holding part 39 and the lifting guide part 40 are connected, and the lifting guide part 40 is located at one end of the push-holding part 39. Because the lifting guide part 40 is arc-shaped, it deviates from the extension direction of the push-holding part 39. The shorter end of the push plate 37 located on the fulcrum side is provided with a bearing 41. The center line of the bearing 41 is perpendicular to the extension direction of the push plate 37, and the bearing 41 is embedded in the guide groove 38. After the push plate 37 moves on the guide plate 35, when one end of the push plate 37 is in the push-holding part 39, the other end of the push plate 37 remains in a vertical position. After one end of the push plate 37 enters the lifting guide part 40, the other end of the push plate 37, which is the longer end on the other side of the fulcrum, changes from a vertical position to an inclined position and finally to a horizontal position.

[0065] The power assembly III 42 includes a synchronous belt, pulleys, a splined shaft 43, a motor, and a reducer. The motor and reducer are combined and mounted on the mounting frame 19. The motor is mounted on the mounting frame 19 via the reducer, and both the motor and reducer are located on one side of the mounting frame 19. A pulley is mounted on the output shaft of the reducer. The splined shaft 43 is movably mounted on the mounting frame 19, and its centerline is parallel to the guide rod 25 of the first-stage translation component 21. The splined shaft 43 can rotate on the mounting frame 19. A pulley is also mounted on the splined shaft 43. The splined shaft 43 is connected to the reducer via a transmission belt mounted on the pulley. A synchronous belt is mounted on the carrier 24 via pulleys. One of the pulleys is movably connected to the splined shaft 43. A drive key is located on the inner side of the pulley, and the pulley connects to the splined shaft 43 via this key. The pulley can translate along the centerline of the splined shaft 43. When the splined shaft 43 rotates, it drives the synchronous belt. The synchronous belt, mounted on the pulleys, unfolds on the carrier 24 to form a straight section. This straight section serves as the power output section and is fixedly connected to the slide table 36. When the power assembly Ⅲ 42 drives the slide table 36, the push plate 37 is also driven.

[0066] The linear push unit is a linear cam structure. The push plate 37 is constrained by the slide table 36 and the guide plate 35 at the guide groove 38, causing the push plate 37 to change its spatial orientation according to the structure of the guide groove 38. The range of motion of the push plate 37 intersects with the material conveying channel. The end of the push plate 37 that can extend into the material conveying channel is the longer end of the push plate 37 on the other side of the fulcrum. After being driven, the push plate 37 moves along the guide plate 35, and the orientation of the end that can extend into the material conveying channel includes vertical, inclined, and horizontal orientations. When the end of the push plate 37 extends into the material conveying channel, it only presents a vertical orientation; when it is out of the material conveying channel, it presents an inclined and horizontal orientation.

[0067] In the initial state, the inlet unit 1 is in a retracted state, so that all the rollers of the frame 11 in the output unit 2 are on the horizontal support surface 18; the push plate 37 is detached from the material conveying channel and is in a horizontal position, and is located close to the conveying frame 4.

[0068] In use, a truck tows the container into the warehouse area and places it in front of the platform. The bottom of the container door contacts the vertical part of the guide ramp 17, and the floor inside the container is at the same height as the vertical part and lower than the height of the horizontal support surface 18. The conveyor line for transporting goods in the warehouse is connected to the conveyor section 44 on the conveyor frame 4 so that items on the conveyor line in the warehouse can directly enter the conveyor section 44 of the conveyor frame 4.

[0069] The inlet unit 1 activates power components IV6 and V7, driving the sub-main frame and conveyor frame 4 to move away from the fixed base 3, and the entire inlet unit 1 changes from a retracted state to an extended state. At the same time, the frame 11 is pushed by the conveyor frame 4 and moves, with the rollers continuously rolling on the horizontal support surface 18, pushing the output unit 2 into the container. Initially, all rollers are in contact with the horizontal support surface 18. Then, the roller furthest from the conveyor frame 4 extends above the guide ramp 17 and is suspended in the air. At this time, the weight of the output unit 2 is borne by the roller closest to the conveyor frame 4. Next, the roller closest to the conveyor frame 4 leaves the horizontal support surface 18 and begins to contact the guide ramp 17. The roller furthest from the conveyor frame 4 is still suspended in the air, and the weight of the output unit 2 is borne by the roller closest to the conveyor frame 4. Then, the roller furthest from the conveyor frame 4 contacts the floor inside the container. The roller closest to the conveyor frame 4 begins to tend to leave the guide ramp 17, and the responsibility for bearing the weight of the output unit 2 begins to transfer from the roller closest to the conveyor frame 4 to the roller furthest from the conveyor frame 4. Finally, all rollers are in contact with the floor inside the container, and all rollers bear the weight of the output unit 2.

[0070] During the process of the output unit 2 entering the container, there is relative movement between the frame 11 and the conveyor frame 4. The conveyor frame 4 changes position in the horizontal direction but does not change position in the vertical direction. The frame 11 moves closely following the working surface 16 or the ground inside the container due to gravity, so that the frame 11 changes position in the horizontal direction while changing position in the vertical direction.

[0071] When the output unit 2 extends into the container and reaches the predetermined position, the output unit 2 is located at the center of the width direction of the container's internal space. The position of the conveying channel needs to be adjusted to ensure that the load-bearing component 20 is in the initial position and close to the conveying frame 4, so that the conveying channel is connected to the conveying part 44 of the conveying frame 4, and the items conveyed by the conveying part 44 can be directly fed into the conveying channel.

[0072] During operation, items are first conveyed into the material conveying channel by the conveying part 44 of the conveying frame 4. After the load-bearing component 20 loads the items, its spatial position changes according to the target position, i.e., the stacking position. If the target position is lower, the load-bearing component 20 is placed in the corresponding lower position until the material conveying channel can be placed within the target position. If the target position is higher, the load-bearing component 20 is placed in the corresponding higher position until the material conveying channel can be placed within the target position. The item stacking operation is carried out in a layered manner. Depending on the spatial orientation of the target position, the load-bearing component 20 may undergo forward and backward translation / descending / forward and backward translation, forward and backward translation / descending / left and right translation / forward and backward translation, forward and backward translation only, forward and backward translation / rising / forward and backward translation, and forward and backward translation / rising / left and right translation / forward and backward translation. The initial position of the load-bearing component 20 is not located at the bottom of the entire output unit 2, so the load-bearing component 20 can perform a descending action after carrying the items.

[0073] To illustrate the operation of the load-carrying output component 9, this embodiment specifically describes the process of placing items in the middle or upper layers, i.e., the process of the load-bearing component 20 performing forward / backward translation, upward movement, left / right translation, and forward / backward translation. Initially, the items are fed into the conveying channel via the conveying frame 4. Next, the secondary translation component 22 drives the load-bearing component 20 towards the conveying section 44 that is detached from the conveying frame 4, until one end of the load-bearing component 20 is no longer directly above the bottom of the frame 11. This action ensures that the load-bearing component 20 will not be obstructed by the frame 11 during subsequent lifting movements. The lifting component 13 drives the lifting frame 12 upward, causing the load-bearing component 20 to rise. Once the predetermined height is reached, if a long-distance left-right translation of the load-bearing component 20 is required, the third-level translation component 14 is activated to drive the mounting frame 19 to move. This will result in a significant left-right translation of the load-bearing component 20. Then, the first-level translation component 21 drives the load-bearing component 20 to translate left and right, causing it to reach the predetermined position after a small amount of left-right translation. Of course, if a long-distance left-right translation of the load-bearing component 20 is not required when the predetermined height is reached, the first-level translation component 21 directly drives the load-bearing component 20 to perform left-right translation. Next, the second-level translation component 22 drives the load-bearing component 20 to perform forward and backward translation, and the load-bearing component 20 moves further away from the conveying frame 4, causing it to protrude from the other side of the mounting frame 19, i.e., in front of the entire output unit 2. Finally, the push plate 37 on the unidirectional pushing component 23 is driven, moving away from the conveying frame 4 and towards the location of the conveying channel. The push plate 37 then enters the conveying channel vertically. When the push plate 37 presses against the item and applies a pushing force away from the conveying frame 4, the secondary translation component 22 drives the load-bearing component 20 in the opposite direction. The load-bearing component 20 begins to move towards the conveying frame 4, causing the item to detach from the conveying channel. After all components are reset, the next item is stacked.

[0074] After the items are stacked in a row, the power unit V7 drives the conveyor frame 4 to move outward from the container. The movement between the conveyor frame 4 and the auxiliary frame 5 tends towards a contraction state, moving the output unit 2 away from the just-stacked items to leave enough space for the next row of items to be stacked. The power unit V7 is based on a lead screw transmission structure, thus possessing precise motion control characteristics. The small-range movement of the output unit 2 is driven and controlled by the power unit V7.

[0075] After implementing this technical solution, it can replace manual labor, complete handling and lifting operations, and achieve the technical goal of mechanized, non-destructive, and efficient palletizing and packing.

[0076] The second embodiment of the present invention differs from the first embodiment in that it does not include a three-stage translation component, and the lifting frame of the movable lifting component is directly connected to the mounting frame of the load output component.

[0077] In the third embodiment of the present invention, the difference between this embodiment and the first embodiment is that no one-way pushing component is set. After the load-bearing component carries the item to the target position, the worker only needs to use the workpiece to hold the item, and the load-bearing component moves towards the direction of the conveying frame, so that the load-bearing component and the item will generate relative movement, so that the item will be separated from the conveying channel and fall directly into the stacking position.

[0078] The fourth embodiment of the present invention differs from the first embodiment in that the conveying frame is directly mounted on the fixed base via a guide rail. The guide rail includes a linear slide rail and a sliding sleeve. The linear slide rail is fixed horizontally to the inner side of the fixed base, and the guide sleeve is fixed to the outer side of the conveying frame.

[0079] The fifth embodiment of the present invention differs from the third embodiment in that it does not include a three-stage translation component, and the lifting frame of the movable lifting component is directly connected to the mounting frame of the load output component.

[0080] The sixth embodiment of the present invention differs from the fourth embodiment in that it does not include a three-stage translation component, and the lifting frame of the movable lifting component is directly connected to the mounting frame of the load output component.

[0081] The seventh embodiment of the present invention differs from the second embodiment in that it does not include a one-way pushing component. After the load-bearing component carries the item to the target position, the worker only needs to use the workpiece to hold the item in place. The load-bearing component moves towards the direction of the conveying frame, causing relative movement between the load-bearing component and the item. In this way, the item is detached from the conveying channel and falls directly into the stacking position.

[0082] The eighth embodiment of the present invention differs from the fourth embodiment in that it does not include a one-way pushing component. After the load-bearing component carries the item to the target position, the worker only needs to use the workpiece to hold the item in place. The load-bearing component moves towards the direction of the conveying frame, causing relative movement between the load-bearing component and the item. In this way, the item is detached from the conveying channel and falls directly into the stacking position.

[0083] The ninth embodiment of the present invention differs from the second embodiment in that the conveying frame is directly mounted on the fixed base via a guide rail. The guide rail includes a linear slide rail and a sliding sleeve. The linear slide rail is fixed horizontally to the inner side of the fixed base, and the guide sleeve is fixed to the outer side of the conveying frame.

[0084] The tenth embodiment of the present invention differs from the third embodiment in that the conveying frame is directly mounted on the fixed base via a guide rail. The guide rail includes a linear slide rail and a sliding sleeve. The linear slide rail is fixed horizontally to the inner side of the fixed base, and the guide sleeve is fixed to the outer side of the conveying frame.

[0085] In the eleventh embodiment of the present invention, this embodiment differs from the fourth embodiment in that a power assembly V is provided between the conveying frame and the fixed base. The power assembly V includes a motor, a reducer, a lead screw, and a lead screw sleeve. The lead screw is mounted on the fixed base. The motor is connected to the reducer and is also mounted on the fixed base via the reducer. The output shaft of the reducer is connected to the lead screw.
