Description

Technical Field

[0001] The present invention relates to the technical field of riveting equipment, and in particular to an alternating feeding platform and a riveting device. Background Art

[0002] Traditional rotary riveting equipment relies on manual placement of workpieces before processing and manual replacement of workpieces after processing to maintain continuous riveting operation, which is inefficient. To address this shortcoming, there are mainly two solutions for existing rotary riveting equipment in terms of handling the loading structure. The first is to adopt a single-platform design. This design usually requires a round trip of processing to be completed before the workpiece can be replaced, resulting in a long standby time for the equipment, which in turn affects the processing efficiency. The second solution is to adopt a multi-platform design. Although it effectively solves the problem of long workpiece replacement time on a single platform, it also brings new challenges: the multi-platform structure is large in size and occupies a large amount of remaining space in the equipment, which limits the room for improvement of other structures of the equipment and makes further optimization difficult.

[0003] For example, the Chinese invention patent with publication number CN116460245A discloses a dual-platform riveting device, including: a three-axis riveting machine and a jig. The three-axis riveting machine includes a workbench, on which two parallel movable platforms are arranged. The guide sleeve is fixedly mounted on the jig base plate, and the position of the guide sleeve corresponds to the first push rod. The guide column is passed through the bearing sleeve, and the guide column is passed through the jig base plate. The product is placed on the stripper plate, and the module is fixedly mounted on the jig base plate. The top of the module contacts the product after passing through the stripper plate. The rivet pin is arranged in the module, and the rivet is placed in the positioning groove of the module. The bottom of the rivet contacts the top of the rivet pin. Compared with the existing technology, this application can complete the riveting work of multiple and various rivets on the product at one time. However, the arrangement of the two movable platforms takes up a lot of space, which to a certain extent limits the improvement of other equipment structures. Summary of the Invention

[0004] The present application aims to solve at least one of the above-mentioned technical defects. In view of this, the present application provides an alternating loading platform, which can reduce the standby time of the equipment and solve the technical defect in the prior art that the multi-platform loading structure occupies too much space.

[0005] The present invention provides an alternating loading platform, which includes a first platform assembly and a second platform assembly, wherein the first platform assembly includes a lifting cylinder and a first platform arranged on the top of the lifting cylinder, and a first guide sliding assembly is provided at the bottom of the lifting cylinder; the second platform assembly includes a sliding base, a second guide sliding assembly arranged on the sliding base, and a second platform arranged on the top of the second guide sliding assembly, the first guide sliding assembly is arranged below the sliding base, the lifting cylinder is located on the outside of the sliding base, and the first platform is located above the second guide sliding assembly.

[0006] The first guide assembly drives the lifting cylinder and the first platform for linear movement, while the lifting cylinder steadily raises the first platform. The second guide assembly enables the second platform to translate horizontally on a sliding base. The sliding base provides a mounting base for the second guide assembly, allowing the second platform to be aligned with the first platform, ensuring consistent riveting quality. The sliding base also increases the installation height of the second guide assembly, preventing collisions between the components of the first and second platform assemblies. Subsequently, after the first and second platform assemblies are combined, the first guide assembly slides beneath the sliding base, driving the first platform to translate horizontally above the first guide assembly. The lifting cylinder is located outside the sliding base, preventing collisions with the second platform. Simultaneously, the lifting cylinder raises the first platform, moving it above the second platform. The second platform then moves away from the first platform, allowing the two platforms to interchange positions. This allows for alternate loading of workpieces by installing workpiece fixtures on the first and second platforms. Through this design, the alternating loading platform not only overcomes the disadvantage of low loading efficiency of the traditional single-platform loading structure, but also effectively reduces the structural volume through a compact and reasonable structural design, successfully solving the pain points faced by the existing multi-platform loading structure.

[0007] In a preferred technical solution of the present invention, the first guide sliding assembly includes a sliding plate, the lifting cylinder is arranged on the top of the sliding plate, a first slider is provided at the bottom of the sliding plate, and the bottom of the first slider is slidably connected to a guide rail; the second guide sliding assembly includes a sliding rail arranged on the top of the sliding base, a second slider is provided on the sliding rail, and the second platform is arranged on the second slider.

[0008] The sliding plate connects the first slider and the lifting cylinder, driving the first platform to slide along the guide rail. Multiple lifting cylinders can be connected to the sliding plate to ensure balanced support for the first platform. The sliding plate is located below the sliding base, effectively saving space. The second platform is mounted on the second slider and achieves horizontal displacement through the sliding connection between the second slider and the guide rail.

[0009] In a preferred technical solution of the present invention, a synchronization mechanism is provided on the sliding base, and the synchronization mechanism connects the sliding plate and the second platform, and is used for simultaneously driving the sliding plate and the second platform to move relative to each other.

[0010] The synchronization mechanism connects the sliding plate and the second platform to achieve synchronous drive. This alternating loading platform uses a synchronization mechanism to replace the manual push-pull of the first and second platforms to achieve automated loading. This not only prevents accidental injuries and ensures personnel safety, but also improves the efficiency of alternating loading, facilitating production.

[0011] In a preferred technical solution of the present invention, the synchronization mechanism includes a synchronous motor and a rotating shaft, and the synchronous motor and the rotating shaft are both installed on the sliding base, and sleeves are provided on the driving end of the synchronous motor and the rotating shaft, and a synchronous belt is wound around the two sleeves, and the synchronous belt connects the sliding plate and the second platform.

[0012] Among them, the synchronous motor drives the synchronous belt to rotate. The rotating shaft is connected to one end of the synchronous belt to tension the synchronous belt and ensure that its other end is in close contact with the driving end of the synchronous motor, thereby effectively improving the transmission efficiency of the synchronous belt. In addition, the sleeve acts as a limiter to prevent the synchronous belt from falling off. At the same time, the sliding plate and the second platform are respectively connected to the two sides of the synchronous belt to obtain the function of counter-movement. Through this design, the sliding plate and the second platform can achieve relative movement under the drive of the synchronous belt. With this simple structural design, the synchronous mechanism can realize the automation of the loading process without significantly increasing the size of the equipment.

[0013] In a preferred technical solution of the present invention, a pressure plate is fixed on the top surface of the sliding plate, a gap is left between the pressure plate and the sliding plate, and the synchronous belt passes through the gap between the pressure plate and the sliding plate; a transmission part is fixed on the bottom of the second platform, and the synchronous belt is passed through the transmission part.

[0014] The gap between the pressure plate and the sliding plate is narrow, and the synchronous belt will be in close contact with the pressure plate after passing through the gap. Therefore, the displacement movement of the synchronous belt can be transmitted from the pressure plate to the sliding plate, and then from the sliding plate to the first platform, so that the first platform can achieve translation. In addition, the abutment effect of the pressure plate also helps to prevent the synchronous belt from deviating. Obviously, this design is not only simple and easy to install, but also uses very few consumables. The transmission member is used to connect the synchronous belt and the second platform, thereby realizing the transmission of the translational movement of one side of the synchronous belt. The close fit between the transmission member and the synchronous belt effectively reduces energy loss and significantly improves the transmission efficiency of the equipment.

[0015] In a preferred technical solution of the present invention, a lifting cylinder is further provided on the sliding base, and a driving end of the lifting cylinder abuts against the bottom of the second platform.

[0016] Among them, the lifting cylinder is located below the second platform, and its driving end abuts against the second platform upward. By lifting or supporting the second platform, it can be lifted and lowered vertically, which can provide support force for the workpiece during the processing, thereby pressing the workpiece and improving the strength and reliability of the riveting.

[0017] In a preferred technical solution of the present invention, a boss is provided on the driving end of the lifting cylinder, and a fitting hole matching the size of the boss is opened on the second platform.

[0018] Among them, the boss abuts the second platform, and the second platform is provided with an interlocking hole corresponding to the boss. Therefore, the lifting cylinder can be embedded in the interlocking hole through the boss to improve the connection stability, effectively preventing the shaking of the second platform caused by vibration during the riveting process, and further improving the quality and efficiency of the riveting of the workpiece.

[0019] In a preferred technical solution of the present invention, the alternating loading platform further includes a mounting base, the sliding base and the first guide sliding assembly are both detachably connected to the mounting base, and handles are provided on both sides of the mounting base.

[0020] The first platform assembly is connected to the mounting base via a first guide assembly, while the second platform assembly is connected to the mounting base via a sliding base. The mounting base thus serves as a common support platform for both the first and second platform assemblies, enabling the overall movement of the alternating loading platform, thereby promoting overall modularization. Furthermore, to enhance mobility, handles are provided on both sides of the base for easy gripping, making transport easier and more efficient.

[0021] In a preferred technical solution of the present invention, a hinge is provided on the mounting base, one end of the hinge is fixed to the mounting base, and the other end of the hinge is fixed to the first guide slide assembly.

[0022] Wherein, because the first guide slide assembly is connected to the mounting base, it can slide smoothly on the mounting base. At this time, the mounting base and the first guide slide assembly are fixedly connected by a hinge, thereby effectively limiting the movement stroke of the first platform and helping the first platform to be parked and positioned.

[0023] The present application further provides a rotary riveting device, which includes a device body, in which the alternating feeding platform as described above is provided.

[0024] The machine loads materials onto the first and second platforms separately, and alternates them to achieve processing, thereby ensuring the continuity of the processing and effectively reducing standby time. Furthermore, the use of alternating loading platforms can fully free up space within the machine body, helping to further optimize the machine structure.

[0025] From the technical solutions introduced above, it can be seen that the alternating loading platform provided in the embodiment of the present application realizes the alternating loading function by installing workpiece fixtures on the first platform assembly and the second platform assembly. In addition, the first platform assembly and the second platform assembly adopt a stacking design, which significantly reduces the overall volume of the platform and effectively improves the space utilization. Specifically, the first platform assembly adopts a lifting cylinder to drive the first platform, and drives the first platform through the first guide sliding assembly to realize the vertical lifting and horizontal movement of the first platform; the second platform assembly fixes the second guide sliding assembly through a sliding base, and adopts a guide sliding structure to enable the second platform to move smoothly in the horizontal direction. Through the spatial coordination of the first platform assembly and the second platform assembly, the alternating loading platform can lift the first platform and perform relative displacement between the two platforms, thereby achieving the effect of alternating loading, while shortening the distance between the first platform and the second platform, significantly reducing the overall volume, and solving the problem of excessive space occupied by the multi-platform layout in the existing riveting equipment.

[0026] In addition, an embodiment of the present application also provides a rotary riveting device, which adopts the aforementioned alternating feeding platform as a feeding structure, effectively releasing the remaining space and creating more possibilities for further improvement.

[0045] Example 1

[0046] See also Figures 1 to 3As shown, the present invention provides an alternating loading platform, which includes a first platform component 1 and a second platform component 2, wherein the first platform component 1 includes a sliding plate 13, two lifting cylinders 11 arranged on both sides of the sliding plate 13 and a first platform 12 arranged on the top of the two lifting cylinders 11, a first slider 14 is provided at the bottom of the sliding plate 13, and the bottom of the first slider 14 is slidably connected to a guide rail 15; the second platform component 2 includes a sliding base 21, two slide rails 24 arranged on the sliding base 21, four second sliders 23 arranged on the two slide rails 24 and a second platform 22 arranged on the top of the four second sliders 23, a sliding plate 13 is provided below the sliding base 21, two lifting cylinders 11 are located on both sides of the sliding base 21, and the first platform 12 is located above the two slide rails 24.

[0047] See also Figure 5 As shown, a lifting cylinder 4 is further provided on the sliding base 21 , and a driving end of the lifting cylinder 4 abuts against the bottom of the second platform 22 .

[0048] See also Figure 5 As shown, a boss 5 is provided on the driving end of the lifting cylinder 4 , and a fitting hole 6 matching the size of the boss 5 is opened on the second platform 22 .

[0049] See also Figure 2 As shown, the alternating loading platform further includes a mounting base 7 , the sliding base 21 and the guide rail 15 can be detachably connected to the mounting base 7 , and handles 71 are provided on both sides of the mounting base 7 .

[0050] See also Figure 2 As shown, a hinge 72 is provided on the sliding plate 13 , one end of the hinge 72 is fixed to the mounting base 7 , and the other end is fixed to the sliding plate 13 .

[0051] As a further improvement of this embodiment, positioning pins are provided on both sides of the sliding base 21, and positioning holes are opened at the bottom of the first platform 12, and the positioning pins match the positioning holes.

[0052] Specifically, the first platform assembly 1 can be provided with two guide rails 15 arranged in parallel, and the two guide rails 15 can be installed on any working plane through a bolt structure, and two first sliders 14 are used on each guide rail 15 to be slidably connected thereto. At the same time, the two ends of the sliding plate 13 are respectively fixed to the two first sliders 14, so that it is mounted on the four first sliders 14 for a horizontal arrangement. Secondly, two lifting cylinders 11 are provided on the top surface of the sliding plate 13, respectively located at the two ends of the sliding plate 13, and the first platform 12 is fixed to the driving ends of the tops of the two lifting cylinders 11, so that the first platform 12 is mounted on the lifting cylinders 11 to form a square frame structure. The second platform assembly 2 can set the sliding base 21 between the two guide rails 15, and the sliding base 21 can be composed of two vertically parallel metal plates, and two positioning grooves are respectively provided on the left and right sides of the top surface of the sliding base 21 to facilitate the positioning and installation of the slide rail 24. Two slide rails 24 are mounted on both sides of the sliding base 21 corresponding to the positioning slots. Two second sliders 23 are slidably connected to each slide rail 24, and then the second platform 22 is placed on the four second sliders 23. Based on the above structure, the sliding plate 13 drives the first platform 12 to slide along the guide rail 15 by connecting the first slider 14 and the lifting cylinder 11. The two lifting cylinders 11 are respectively connected to the two ends of the bottom of the first platform 12, which can smoothly lift the first platform 12 and achieve balanced support for the first platform 12. The second platform 22 is set on the four second sliders 23 and achieves horizontal displacement through the sliding connection between the second sliders 23 and the slide rails 24. The sliding base 21 not only provides the installation foundation of the slide rails 24, but also uses its own height to ensure that the second platform 22 is on the same horizontal plane as the first platform 12. This height also increases the installation height of the slide rails 24, avoiding collisions between the sliding plate 13 and the various components of the second platform assembly 2 during sliding, thereby maintaining structural safety.

[0053] In addition, a notch is provided at the bottom of the sliding base 21, which allows the sliding plate 13 to pass through, thereby setting the sliding plate 13 below the sliding base 21. At the same time, the notch also allows the sliding plate 13 to move horizontally. At the same time, the square frame structure formed by the first platform assembly 1 enables the sliding base 21, slide rail 24, second slider 23 and second platform 22 of the second platform assembly 2 to pass through it, so the first platform 12 can move above the slide rail 24, and then with the help of the lifting of the lifting cylinder 11 and the movement of the second platform 22, it can further cross the second platform 22 to realize the position interchange of the two platforms.

[0054] Furthermore, a lifting cylinder 4 is fixed to the sliding base 21 through a fixed block. The fixed block is fixed between the two sides of the sliding base 21. The lifting cylinder 4 is inserted into the fixed block, and its driving end is exposed on the top surface of the fixed block so as to abut against the bottom surface of the second platform 22. The lifting cylinder 4 lifts the second platform 22 and supports the second platform 22 when it is lowered, so that it can provide support for the workpiece during the processing, thereby pressing the workpiece and improving the strength and reliability of the riveting. Obviously, the first platform 12 can achieve the same workpiece pressing effect through the lifting cylinder 11, so that the riveting quality of the workpieces produced after the first platform 12 and the second platform 22 are loaded is consistent. In addition, to ensure the stability of the second platform 22 during vertical lifting, a boss 5 can be installed on the driving end of the lifting cylinder 4, and a corresponding interlocking hole 6 can be opened at the bottom of the second platform 22, wherein the boss 5 can be a part connected by cylinders with different diameters, and the interlocking hole 6 can be a through hole or a blind hole. By embedding the boss 5 into the fitting hole 6 , the connection stability can be improved, and shaking of the second platform 22 due to vibration during the riveting process can be effectively prevented, thereby further improving the quality and efficiency of the workpiece riveting.

[0055] Furthermore, the first platform assembly 1 and the second platform assembly 2 can be conveniently assembled and moved as a whole via the mounting base 7. A handle 71 can also be used during movement to enhance mobility, making the handling process easier and more efficient. Furthermore, a hinge 72 is fixed to the top surface of the mounting base 7. One end of the hinge 72 is fixed to one side of the middle portion of the guide rail 15, and the other end is fixed to the edge of the sliding plate 13. When the sliding plate 13 slides toward both ends of the guide rail 15, the hinge 72 effectively limits the sliding travel of the sliding plate 13, thereby preventing the first slider 14 at the bottom of the sliding plate 13 from separating from the guide rail 15, thereby improving the reliability of the overall structure.

[0056] Furthermore, brackets are mounted on both sides of the sliding base 21, each with a longitudinal locating pin at its top. At the same time, locating holes are provided at both ends of the bottom surface of the first platform 12. The locating pins can be inserted into the holes to help staff determine the accuracy of the parking position of the first platform 12. For the second platform 22, the accuracy of the parking position of the second platform 22 can be determined by inserting the boss 5 into the fitting hole 6.

[0057] The specific implementation process is as follows: First, a workpiece fixture is installed on the first platform 12 and the second platform 22. Then, a workpiece to be processed is pre-placed on the first platform 12, and the first platform 12 is lifted using the lifting cylinder 11. Simultaneously, the first platform 12 is manually advanced to move above the second platform 22. Next, the second platform 22 is pulled to the initial parking position of the first platform 12, ultimately swapping the positions of the first and second platforms 12 and 22.

[0058] The workpiece on the first platform 12 can then be processed. During the riveting process, the lifting cylinders 11 on either side of the first platform 12 rise to provide support and, in conjunction with the riveting head, press the workpiece against the riveting head. At this point, the worker can pre-position the workpiece to be processed on the second platform 22. After the previous workpiece is processed, the lifting cylinders 11 descend, moving the workpiece on the first platform 12 away from the riveting head. The first platform 12 is then pulled back above the second platform 22, which then pushes the second platform 22 back to its initial position, completing a secondary positional swap between the two platforms.

[0059] Next, the lifting cylinder 4 cooperates with the riveting head to carry out the collaborative processing, and at the same time, the workpiece can be pre-set on the first platform 12 again. After the workpiece on the second platform 22 is processed, the second platform 22 is lowered to the initial height, so that the first platform 12 can be moved above it. This operation is repeated to achieve continuous material loading for riveting.

[0060] Example 2

[0061] See also Figure 4 As shown, based on the improvement of Example 1, this embodiment provides an alternating loading platform. A synchronization mechanism 3 is provided on the sliding base 21. The synchronization mechanism 3 connects the sliding plate 13 and the second platform 22 and is used to simultaneously drive the sliding plate 13 and the second platform 22 to move relative to each other. The synchronization mechanism 3 includes a synchronous motor 31 and a rotating shaft 32. The synchronous motor 31 and the rotating shaft 32 are both mounted on the sliding base 21. Sleeves 33 are provided on the driving end of the synchronous motor 31 and the rotating shaft 32. A synchronous belt 34 is wound around the two sleeves 33. The synchronous belt 34 connects the sliding plate 13 and the second platform 22.

[0062] See also Figure 4 As shown, a pressing plate 35 is fixed to the top surface of the sliding plate 13 , a gap is left between the pressing plate 35 and the sliding plate 13 , and the synchronous belt 34 passes through the gap between the pressing plate 35 and the sliding plate 13 .

[0063] See also Figure 4 As shown, a transmission member 36 is fixed to the bottom of the second platform 22 , and the synchronous belt 34 is passed through the transmission member 36 .

[0064] Specifically, the synchronous motor 31 drives the synchronous belt 34 to rotate, thereby driving the first platform 12 and the second platform 22 to move synchronously, achieving counter-movement. This embodiment uses a servo motor, which features precise speed control and positioning capabilities. This ensures that the synchronous belt 34 drives the sliding plate 13 and the second platform 22 to achieve precise synchronous movement, thereby improving loading accuracy. Furthermore, the servo motor has an overload protection function that automatically shuts down in the event of an abnormality, preventing equipment damage and further ensuring production safety.

[0065] The sliding base 21 has a through-hole through which the drive end of the synchronous motor 31 passes from the outside of the sliding base 21 and is connected to the sliding base 21 via a metal plate. The rotating shaft 32 and the synchronous motor 31 are mounted on the same side of the sliding base 21, with the rotating shaft 32 positioned between the two sides of the sliding base 21. A toothed sleeve 33 is used on the rotating shaft 32 and the drive end of the synchronous motor 31 to ensure close contact with the toothed synchronous belt 34, effectively improving the transmission efficiency of the synchronous belt 34. The sleeve 33 also serves as a limiter, preventing the synchronous belt 34 from falling off.

[0066] On the first platform 12, a pressure plate 35 is bolted to the top surface of the sliding plate 13. This pressure plate 35 is secured to the sliding plate 13 by a narrow gap, passing through the underside of the synchronous belt 34. This gap allows the pressure plate 35 to transmit the displacement of the synchronous belt 34 to the sliding plate 13, and then to the first platform 12, enabling translation of the first platform 12. Furthermore, the abutment of the pressure plate 35 helps prevent the synchronous belt 34 from deviating. Furthermore, the pressure plate 35 can have a toothed surface in the gap, meshing with the toothed synchronous belt 34 to increase friction and enhance transmission efficiency. The second platform 22 is connected to the synchronous belt 34 via a transmission member 36 at its bottom. Specifically, a narrow gap is defined in the transmission member 36, through which the upper side of the synchronous belt 34 passes. Furthermore, the transmission member 36 is provided with an anti-slip material in this gap to enhance friction with the synchronous belt 34. As a more preferred option, a toothed structural surface that meshes with the toothed synchronous belt 34 can be provided in the gap of the transmission member 36 to effectively reduce energy loss and improve the transmission efficiency of the equipment.

[0067] Through the above design, the alternating loading platform utilizes the synchronization mechanism 3, replacing manual pushing and pulling of the first platform 12 and the second platform 22. Driven by the synchronous belt 34, the sliding plate 13 and the second platform 22 can achieve relative movement. With this simple structural design, the synchronization mechanism 3 automates the loading process without significantly increasing the size of the equipment. This not only prevents accidental injuries and ensures personnel safety, but also improves the efficiency of alternating loading, facilitating production.

[0068] Example 3

[0069] See also Figure 6 As shown, this embodiment provides a rotary riveting device, which includes a device body 8, in which the alternating feeding platform as described above and a riveting mechanism are provided. The riveting mechanism is provided with a lifting slide and a riveting assembly arranged on the lifting slide, and the riveting assembly is located above the alternating feeding platform.

[0070] Specifically, the device loads materials on the first platform 12 and the second platform 22 respectively, and realizes alternating processing by interchanging the positions of the first platform 12 and the second platform 22, thereby ensuring the continuity of the processing process and effectively reducing the standby time. Among them, the riveting assembly includes a high-precision servo motor, a planetary reducer and a detachable rivet head. The high-precision servo motor is connected to the input shaft of the planetary reducer through a coupling, and the output shaft of the planetary reducer is rigidly connected to the detachable rivet head, providing stable torque and speed for the detachable rivet head. In the vertical direction, the riveting assembly is mounted on a lifting slide. At the same time, two vertical linear rails are installed on the main body 8 of the device. The lifting slide is slidably connected to the rails by setting a slider on one side, so that the riveting assembly can be vertically lifted and lowered with the lifting slide. The lifting slide can use a servo electric cylinder as a drive device. The servo electric cylinder is mounted on the top of the main body of the device 8, and its output end is connected to the top of the lifting slide. Driven by the servo electric cylinder, the lifting slide can move precisely on the Z axis.

[0071] To facilitate precise control, the equipment is also equipped with a sophisticated control system. This system precisely controls the movement of the servo motor and servo cylinder, as well as the movement of the synchronous motor 31, ensuring precise vertical and horizontal positioning of the riveting assembly and the first and second platforms 12 and 22. Through a pre-set program, the control system automatically adjusts the operating parameters of the riveting assembly to accommodate workpieces of varying specifications and materials, thereby improving processing efficiency and quality. The equipment also features fault diagnosis and alarm functions. In the event of a fault or abnormality, the system immediately issues an alarm and displays fault information, facilitating timely action by the operator and ensuring stable operation.

[0072] The equipment also features an automatic feeding mechanism equipped with a conveyor belt and a six-axis industrial robotic arm. The conveyor belt is driven by a variable-frequency motor, allowing it to adjust its speed according to the processing rhythm. A six-axis industrial robot is mounted on one side of the machine, and its end effector is equipped with a hydraulic gripper to adapt to workpieces of varying shapes. The conveyor belt transports workpieces, combined with the robotic arm's retrieval function, replacing manual workpiece placement. The robotic arm can also remove finished workpieces, further optimizing the manual unloading process and achieving full automation of both loading and unloading.
