Description

Technical Field

[0001] This application relates to the field of material packaging vehicle devices, and in particular to a tilting container automatic loading system. Background Technology

[0002] Material bags are typically used to contain materials (such as cement, chemical raw materials, and food crops). After production by the equipment, the material bags need to be arranged in an orderly manner in containers for easy transportation, and then transported to designated locations via containers.

[0003] Normally, when a freight truck carrying a container arrives at the loading point, the truck's tailgate will open, and the packages will be moved into the container in an orderly manner using manual or robotic arm handling. At this time, the packages are placed horizontally along the container. To facilitate handling, space needs to be reserved between the packages and the top and inner walls of the container. Tests have shown that, taking a 20-foot container as an example, using this method of stacking packages, the container can hold 430 packages without exceeding the effective load of the freight truck.

[0004] However, in practical applications, during the material packing process, because there is reserved handling space between the material pack and the container, the overall space utilization rate of the container is not high when the maximum load of the freight vehicle is not exceeded, which means there is room for improvement. Utility Model Content

[0005] The purpose of this utility model is to improve the space utilization rate of containers when loading material bags. This application provides a flip-type automatic container loading system.

[0006] To achieve the above objectives, the present application provides a tilting container automatic loading system using the following technical solution:

[0007] A tilting container automatic loading system includes a main frame and a feeding module and a robotic arm sequentially arranged on the main frame. The main frame has a through-hole along its thickness direction. A tilting mechanism is arranged below the main frame near the through-hole. The feeding module includes a support frame and a material bag spacing adjustment mechanism arranged on the support frame. The tilting mechanism includes a longitudinal support and a fixed platform rotatably supported on the longitudinal support. When the container is fixed to the fixed platform, the fixed platform carries the container and rotates along the longitudinal support until the rear door of the container is located at the through-hole. The robotic arm then transfers the material bags located on the material bag spacing adjustment mechanism into the container. At this time, the material bags are vertically placed along the container.

[0008] Preferably, the material bag spacing adjustment mechanism includes a transverse conveying component and a longitudinal lifting component. The transverse conveying component includes a first conveying roller group, a second conveying roller group, and a third conveying roller group that are rotatably supported on the support frame in sequence. The longitudinal lifting component is located on the support frame between the second conveying roller groups. When material bags are placed on the first conveying roller group, the second conveying roller group, and the third conveying roller group respectively, the first conveying roller group and the third conveying roller group carry the material bags and move towards the second conveying roller group.

[0009] Preferably, the longitudinal lifting assembly includes a driving member and a lifting part, the lifting part being slidably disposed on the support frame 32 along the height direction of the support frame, and the driving member being fixedly connected to the lifting part.

[0010] Preferably, a sliding assembly is provided on the main frame located between the support frame 32 and the passage, and the robotic arm is mounted on the sliding assembly.

[0011] Preferably, the flipping mechanism further includes a hydraulic push rod, one end of which is hinged to the longitudinal support, and the other end of which is rotatably connected to the fixed platform.

[0012] Preferably, a limiting block is provided at one end of the longitudinal support near the fixed platform, and an abutment block is provided on the fixed platform. When the fixed platform does not rotate along the longitudinal support, the limiting block abuts against the abutment block.

[0013] Preferably, the third conveying roller group includes several conveying rollers, and the external shape of the conveying rollers is polygonal.

[0014] Compared with the prior art, this utility model provides a tilting container automatic loading system, which has the following beneficial effects:

[0015] 1. The finished material packages are orderly delivered to the robotic arm via the feeding module. After the fixed platform is fixedly connected to the container, the fixed platform carries the container and rotates along the longitudinal support, causing the container to flip along the longitudinal support so that the rear door of the container is located at the passage and the rear door of the container is opened. The robotic arm then orderly places the material packages on the feeding module into the container, so that the material packages are placed vertically along the container. Compared with the horizontal placement of the material packages along the container, the vertical placement can accommodate 480 material packages, improving the space utilization of the container.

[0016] 2. Through the cooperation of the first conveying roller group, the second conveying roller group, the third conveying roller group and the longitudinal lifting component, the material bag on the carrier frame is shaped, so that the three material bags fit together to facilitate the transfer by the robotic arm. After the material bag is transferred to the container, there is no need to adjust the material bag again, thus improving the transfer efficiency.

[0017] 3. Because the outer contour of the conveying roller is polygonal, the material inside the bag is evenly dispersed during the conveying process, so that the material inside the bag is evenly distributed. This reduces the probability of uneven bag surface caused by uneven material distribution, thus preventing the bag from being misplaced after the robotic arm transfers the bag into the container.

[0026] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0027] This application discloses a tilting-type automated container loading system. (Refer to...) Figure 1 , Figure 2 as well as Figure 3 A tilting container automatic loading system includes a main frame 1 and a feeding module 2 and a robotic arm 3 arranged sequentially on the main frame 1. The main frame 1 has a through-hole 11 extending along its thickness direction. A tilting mechanism 4 is arranged below the main frame 1 near the through-hole 11. The feeding module 2 includes a support frame 21 and a material bag spacing adjustment mechanism 22 arranged on the support frame 21. The tilting mechanism 4 includes a longitudinal support 41 and a fixed platform 42 rotatably supported on the longitudinal support 41. When the container is fixed to the fixed platform 42, the fixed platform 42 carries the container and rotates along the longitudinal support 41 until the rear door of the container is located at the through-hole 11. The robotic arm 3 then transfers the material bags located on the material bag spacing adjustment mechanism 22 into the container. At this time, the material bags are placed vertically along the container.

[0028] In this embodiment, the robotic arm 3 is a four-axis robot, model M-410iC / 315, with a working radius of 3143 mm and a load capacity of 315 kg.

[0029] Specifically, the feeding module 2 also includes a main conveying mechanism 23 and a reversing mechanism 24. The two ends of the reversing mechanism 24 are connected to the main conveying mechanism 23 and the support frame 21, respectively. The main conveying mechanism 23 is connected to the production equipment and is used to convey the finished material package to the reversing mechanism 24. The reversing mechanism 24 is used to change the conveying direction and conveying path of the material package and convey it to the material package spacing adjustment mechanism 22.

[0030] Furthermore, the main conveying mechanism 23 includes a main conveying frame 231 and a conveyor belt 232 rotatably supported on the main conveying frame 231, thereby achieving the purpose of conveying the material package produced by the production equipment to the reversing mechanism 24.

[0031] Correspondingly, the reversing mechanism 24 includes a first reversing component 241 and a second reversing component 242. The first reversing component 241 includes a guide frame 2411 and a guide belt 2412 rotatably supported on the guide frame 2411. The guide frame 2411 is installed at the end of the main conveyor frame 231 away from the production equipment, and the guide frame 2411 is inclined along the width direction of the main conveyor frame 231, so that the guide frame 2411 is inclined towards the side wall of the main conveyor frame 231 along the width direction. When the material bag comes into contact with the guide belt 2412, the guide belt 2412 is in a rotating state along the guide frame 2411, thereby driving the material bag to be transported in the rotation direction of the guide belt 2412, so as to achieve the purpose of transporting the material bag to the second reversing component 242.

[0032] Meanwhile, the second reversing assembly 242 includes a discharge slide 2421 and a turning roller assembly 2422. One end of the discharge slide 2421 is fixedly connected to the main conveyor frame 231 and is connected to the discharge end of the guide belt 2412. The other end of the discharge slide 2421 is connected to the turning roller assembly 2422, and the turning roller assembly 2422 is connected to the material bag spacing adjustment mechanism 22.

[0033] Therefore, after the material bag is guided by the guide belt 2412 and falls off the main conveyor frame 231, it will fall onto the discharge chute 2421. The material bag will slide along the discharge chute 2421 to the turning roller group 2422 by its own weight, so as to realize the purpose of changing the direction of the material bag. At the same time, the impact force generated during the falling process of the material bag helps to loosen the material in the material bag and reduce the agglomeration of the material in the material bag.

[0034] It should be noted that in this embodiment, the conveyor belt 232 and the guide belt 2412 are driven by independent motor drive modules (conventional drive components in the mechanical field), and their specific composition and working principle will not be described in detail here.

[0035] After the above process, the purpose of changing the transport path and direction of the material package is achieved, improving the space utilization of the main frame 1, and also facilitating the transfer of the material package by the robotic arm 3.

[0036] Reference Figure 1 and Figure 5 A sliding assembly 5 is provided on the main frame 1 located between the support frame 32 and the passage 11, and the robotic arm 3 is slidably mounted on the sliding assembly 5.

[0037] Specifically, the sliding assembly 5 includes a slide rail 51, a slide table 52, a servo motor 53, and a guide wheel (not shown in the figure). The slide table 52 slides and cooperates with the slide rail 51. The robotic arm 3 is mounted on the slide table 52, and the servo motor 53 is mounted on the slide table 52 on one side of the robotic arm 3. The guide wheel is coaxially fixed with the output shaft of the servo motor 53, and the guide wheel abuts against the side wall of the slide rail 51.

[0038] Therefore, when the output shaft of the servo motor 53 rotates, it will drive the guide wheel, which is fixed coaxially with the output shaft of the servo motor 53, to rotate synchronously. Since the guide wheel abuts against the side wall of the slide rail 51, the guide wheel rotates along the side wall of the slide rail 51, so as to realize the purpose of the slide table 52 carrying the robotic arm 3 to move along the slide rail 51, so as to facilitate the transfer of the material bag by the robotic arm 3.

[0039] Reference Figure 1 , Figure 3 as well as Figure 4 The material bag spacing adjustment mechanism 22 includes a transverse conveying component 221 and a longitudinal lifting component 222. The transverse conveying component 221 includes a first conveying roller group 2211, a second conveying roller group 2212, and a third conveying roller group 2213 that are rotatably supported on a support frame 21 in sequence. The longitudinal lifting component 222 is located on the support frame 21 between the second conveying roller groups 2212. When material bags are placed on the first conveying roller group 2211, the second conveying roller group 2212, and the third conveying roller group 2213 respectively, the first conveying roller group 2211 and the third conveying roller group 2213 respectively carry the material bags and convey them to the second conveying roller group 2212.

[0040] First, it should be noted that the first conveying roller group 2211, the second conveying roller group 2212 and the third conveying roller group 2213 are each driven by an independent drive device (such as a motor belt drive module or a motor gear drive module, which are conventional drive components in the mechanical field, and their specific composition and working principle will not be described in detail here).

[0041] Specifically, since the components and shapes of the first conveying roller group 2211, the second conveying roller group 2212 and the third conveying roller group 2213 are the same, for ease of explanation, the third conveying roller group 2213 will be described in detail below.

[0042] The third conveying roller group 2213 includes several conveying rollers 8. The external shape of the conveying rollers 8 is polygonal, such as pentagonal or hexagonal. In this embodiment, preferably, the cross-sectional shape of the conveying rollers 8 is cubic. The specific number of conveying rollers 8 can be increased or decreased according to the usage requirements or the length of the support frame 21. The specific number is not limited here.

[0043] Therefore, after the material bag reaches the third conveying roller group 2213, the material bag will come into contact with the surface of the conveying roller 8. Since the cross-section of the conveying roller 8 is set in a cubic shape, the material bag is in a non-linear state (with up and down fluctuations) when moving along the path of the third conveying roller group 2213, so as to achieve the purpose of shaking the material bag, so as to loosen the material in the material bag, make the material distribution in the material bag relatively uniform, and make the surface of the material bag relatively flat, so as to facilitate the transfer of the material bag by the robotic arm 3. At the same time, it can also make the surface of the material bag relatively flat after the material bag is transferred into the container, without the need for secondary trimming of the material bag.

[0044] Reference Figure 4 The longitudinal lifting assembly 222 includes a driving member 2221 and a lifting part 2222. The lifting part 2222 is slidably disposed on the support frame 32 along the height direction of the support frame 32, and the driving member 2221 is fixedly connected to the lifting part 2222.

[0045] Specifically, the driving component 2221 can be a motor lead screw drive structure. In this embodiment, preferably, the driving component 2221 is a driving cylinder. The lifting part 2222 includes a lifting plate 22221 and support legs 22222. The lifting plate 22221 is located below the second conveying roller group 2212. The piston rod of the driving cylinder is fixedly connected to the lifting plate 22221. Several support legs 22222 are provided, and the several support legs 22222 are evenly distributed on the lifting plate 22221.

[0046] Furthermore, when the piston rod of the drive cylinder moves, the lifting plate 22221 and the supporting leg 22222 move synchronously with the piston rod of the drive cylinder.

[0047] Meanwhile, in order to improve the stability of the lifting plate 22221 and the supporting legs 22222 when they are transported along the support frame 21, two sets of driving cylinders can be used for driving. The two sets of driving cylinders are symmetrically installed on the support frame 21 about the center line of the length direction of the lifting plate 22221.

[0048] Therefore, when material bags are placed on the first conveying roller group 2211, the second conveying roller group 2212, and the third conveying roller group 2213 respectively, the piston rod of the drive cylinder extends to drive the lifting plate 22221 on which the material bag is placed to rise along the support frame 21, so that the material bag is separated from the second conveying roller group 2212. Then, the first conveying roller group 2211 and the third conveying roller group 2213 move in opposite directions along the support frame 21, so that the material bags on the first conveying roller group 2211 and the third conveying roller group 2213 move towards the material bag on the second conveying roller group 2212. Then, the piston rod of the drive cylinder retracts to drive the material bag on the support leg 22222 to abut against the second conveying roller group 2212 again. At this time, the two ends of the material bag on the second conveying roller group 2212 abut against the material bags on the first conveying roller group 2211 and the third conveying roller group 2213 respectively, thus completing the shaping operation of the material bag.

[0049] The purpose is to effectively reduce the gap between the material packages after shaping them, and to make the connection between the material packages relatively compact after the material packages are transferred into the container by the robotic arm 3, which plays a positive role in improving the utilization rate of the container's internal space.

[0050] Reference Figure 1 and Figure 6 The flipping mechanism 4 also includes a hydraulic push rod 43. One end of the hydraulic push rod 43 is hinged to the longitudinal support 41, and the other end of the hydraulic push rod 43 is rotatably connected to the fixed platform 42. A limit block 6 is provided at one end of the longitudinal support 41 near the fixed platform 42, and an abutment block 7 is provided on the fixed platform 42. When the fixed platform 42 does not rotate along the longitudinal support 41, the limit block 6 abuts against the abutment block 7.

[0051] Specifically, a lifting column 411 is slidably mounted on the longitudinal support 41 along the height direction. The lifting column 411 is fixed to the fixed platform 42 by a pin, so that the fixed platform 42 can rotate along the lifting column 411. The lifting column 411 is driven by a hydraulic drive device, so that the lifting column 411 can rise or fall along the height direction of the longitudinal support 41.

[0052] Furthermore, the base of the hydraulic push rod 43 is hinged to the lifting column 411 via a hinge seat, and the output shaft of the hydraulic push rod 43 is rotatably connected to the fixed platform 42.

[0053] Correspondingly, a locking element 421 is installed on the fixing platform 42. The locking element 421 is locked with the locking pin of the container. The locking element 421 can be a stud, which is fixed by thread or a locking structure to lock with the container.

[0054] The limiting block 6 is located on the side wall of the lifting column 411 near the fixed platform 42. When the hydraulic push rod 43 drives the fixed platform 42 to rotate, the limiting block 6 and the abutment block 7 cooperate to limit the extreme angle of rotation of the fixed platform 42 along the lifting column 411.

[0055] Therefore, when it is necessary to flip the container, the container is first locked with the locking device 421. Then, the hydraulic push rod 43 drives the fixed platform 42, which is fixed with the container, to rotate along the lifting column 411 until the rear door of the container faces the passage 11. When the rear door of the container faces the passage 11, the hydraulic drive device starts to work, so that the lifting column 411 carries the container to move towards the passage 11, so that the rear door of the container faces the side of the robotic arm 3. When the rear door of the container is opened, the material bag can be transferred into the container through the robotic arm 3. After the material bag is transferred into the container, the container is hooked up and the rear door of the container is closed. Then, the lifting column 411 carries the container away from the main frame 1. After the container is away from the main frame 1, the hydraulic push rod 43 drives the fixed frame to rotate again, so that the container returns to a horizontal state and the container can be placed on the freight truck.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
