Description

Technical Field

[0001] The present invention generally relates to the technical field of container production, and more particularly to a container side wall storage and upper assembly system. Background Art

[0002] A container generally consists of a chassis, a roof, two side walls, a front end, and a door end. The usual processing method is that each component of the container is processed separately, and then the processed components are assembled to form the whole container. The problem in actual production is that there are differences in production efficiency between the various components of the container and between the various components and the overall assembly. It takes enough time to complete the processing of several sets of container components to assemble a container. Therefore, the pre-processed components need to be temporarily stored and transferred to the assembly platform for assembly and processing. For components with less deformability such as the chassis, they can be stored by stacking or other methods, but the area of ​​the container side wall is large and the sheet material of the side wall itself is relatively thin. If simple stacking or other methods are used for storage, it is very easy to cause the deformation of the side wall and thus affect the assembly quality of the container, and it will also take up a large production space. In addition, during assembly, the stacked side walls need to be transferred to the assembly platform. In actual production, they are usually transferred by manually operating a crane to lift. This production method is inefficient and occupies a lot of manpower. There are also certain safety hazards when the side walls are hoisted.

[0003] Therefore, it is necessary to provide a container side wall storage and upper assembly system to at least partially solve the above problems. Summary of the invention

[0025] Figure 1 A schematic structural diagram of a container side wall storage and upper assembly system according to a preferred embodiment of the present invention; and

[0026] Figure 2 for Figure 1 A schematic diagram of the container side wall storage and upper assembly system is shown. DETAILED DESCRIPTION

[0027] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0028] The container side wall storage and upper assembly system 1 shown in the present invention is used to store the processed container side walls 2 and transfer the container side walls 2 to the assembly platform when assembling the container.

[0029] A preferred embodiment of the container side wall storage and upper assembly system 1 shown in the present invention is described in detail below with reference to the accompanying drawings.

[0030] like Figure 1As shown, the container side wall storage and upper assembly system 1 includes a storage device 10, a conveying device 20, a pusher device 30, a discharge device 40, a receiving device 50, a lifting device 60 and an operating table 70. Since each container has two side walls of the same size, in order to facilitate the assembly of the container, the storage device 10, the conveying device 20, the pusher device 30, the discharge device 40 and the receiving device 50 are all two and symmetrically arranged, so that the lifting device 60 can simultaneously transfer the two side walls constituting the container to the assembly table for assembly, thereby improving production efficiency.

[0031] It should be pointed out that since the storage device 10, the conveying device 20, the pushing device 30, the discharging device 40 and the receiving device 50 are all symmetrically arranged, for the sake of brevity, only one side is described in detail here. It can be understood that the arrangement of the other side is symmetrical and the same as the arrangement of the one side described in detail.

[0032] like Figure 1 The storage device 10 includes a top side toothed chain 11, a bottom side toothed chain 12 and a support frame 13. The support frame 13 includes a horizontal base 131 and two vertical frames 132 fixedly connected to the base 131 and arranged at a predetermined distance. The top side toothed chain 11 and the bottom side toothed chain 12 of the same storage device 10 are fixedly connected to the same vertical frame 132 in the vertical direction. The top side toothed chain 11 and the bottom side toothed chain 12 are both toothed chain structures similar to the form of a conveyor belt and can rotate around their respective two axes. The outer surface of the toothed chain is provided with a series of teeth extending along the width direction of the toothed chain and arranged along the length direction of the toothed chain. The teeth have a predetermined height, and tooth grooves are formed between two adjacent teeth to clamp the bottom and / or top edges of the container side wall 2 for fixing. The distance between the top side tooth chain 11 and the bottom side tooth chain 12 in the vertical direction is adapted to the height of the container side wall 2, so that the top side and the bottom side of the container side wall 2 can be clamped in the corresponding tooth grooves in the vertical direction on the lower surface of the top side tooth chain 11 and the upper surface of the bottom side tooth chain 12, respectively. Storing in a vertically placed state can prevent the container side wall 2 from being subjected to forces other than the force related to its own gravity, thereby effectively preventing the container side wall 2 from being deformed during storage and thus affecting the assembly quality of the container. The top side tooth chain 11 and the bottom side tooth chain 12 can rotate around their respective axes respectively so that the lower surface of the top side tooth chain 11 and the upper surface of the bottom side tooth chain 12 can be synchronously moved from the outside to the inside of the storage device 10, so as to continuously clamp and fix the newly transferred container side wall 2 on the storage device 10, and separate the container side wall 2 located on the inside.

[0033] The conveying device 20 is used to transfer the container side wall 2 from the production station to the storage device 10. Therefore, the end of the conveying device 20 is arranged outside the storage device 10, and the starting end is arranged between the downstream of the production station of the container side wall 2 and the storage device 10 according to the specific arrangement of the stations in the production workshop. The conveying device 20 includes a longitudinal chain conveying roller 21 and a vertically arranged conveying wall 22 extending from the starting end to the end and extending in parallel. The moving direction of the longitudinal chain conveying roller 21 is perpendicular to the top side tooth chain 11 and the bottom side tooth chain 12 of the storage device 10, so that the length direction of the container side wall 2 is parallel to the tooth groove direction of the top side tooth chain 11 and the bottom side tooth chain 12 when the container side wall 2 is transferred from the longitudinal chain conveying roller 21 to the storage position. In order to ensure that the container side wall 2 remains in a stable position during the transfer from the production station to the storage position, the container side wall 2 leans on the conveying wall 22 in a roughly inclined state. A conveying roller along the transfer direction is arranged at the position where the conveying wall 22 contacts the top edge of the container side wall 2, and the container side wall 2 is moved by rolling, so as to avoid deformation or damage of the container side wall 2 due to friction, and also reduce the wear of the conveying wall 22. Preferably, the height of the longitudinal chain conveying roller 21 close to the storage device 10 is slightly higher than the height of the longitudinal chain conveying roller 21 away from the storage device 10. Such an arrangement is conducive to keeping the container side wall 2 in a stable inclined state during the transfer process from the production station to the storage position, and preventing the container side wall 2 from sliding off the conveying device 20 under gravity or other effects, thereby causing a safety accident.

[0034] The container side wall 2 is transferred to the storage position in a roughly inclined state on the conveying device 20, but the container side wall 2 is placed in the storage device 10 in a vertically placed state. Therefore, a pushing device 30 is provided on the outer side of the end of the conveying device 20 to transfer the container side wall 2 from the conveying device 20 to the storage device 10, and also to adjust the placement state of the container side wall 2. The pushing device 30 includes an upper pushing cylinder 31 and a lower pushing cylinder 32. The upper pushing cylinder 31 is arranged at an upper position in the middle of the container side wall 2, and the lower pushing cylinder 32 is arranged at a position close to the bottom edge of the container side wall 2. When the container side wall 2 is transferred from the conveying device 20 to the storage device 10, the upper pushing cylinder 31 and the lower pushing cylinder 32 act simultaneously to apply a thrust to the container side wall 2 toward the storage device 10, so as to push the container side wall 2 from the conveying device 20 to the storage device 10. At the same time, the action stroke of the upper push cylinder 31 is set to be slightly larger than the action stroke of the lower push cylinder 32 to adjust the container side wall 2 from an inclined state to a vertical state. Preferably, multiple groups of push devices 30 are set along the length direction of the container side wall 2. The simultaneous operation of multiple groups of push devices 30 can make the container side wall 2 evenly stressed, avoiding tipping or other safety accidents caused by uneven stress.

[0035] When assembling a container, it is necessary to first separate the container side wall 2 from the storage device 10 and then transfer it to the final assembly platform, wherein the separation process requires the cooperation of the discharging device 40 and the receiving device 50. The discharging device 40 is a discharging cylinder arranged at a position close to the inner side of the toothed chain 11 at the top edge of the storage device 10, and is used to apply a force to the container side wall 2 at the inner edge of the storage device 10 that is about to be separated from the clamping and fixing of the toothed groove to make it move away from the storage device 10 so that the container side wall 2 is separated from the storage device 10. The force applied by the discharging device 40 to the container side wall 2 acts on the upper part of the container side wall 2 near the top edge. Similar to the pushing device 30, multiple groups of the discharging device 40 can also be arranged along the length direction of the container side wall 2 so that the container side wall 2 is subjected to uniform force.

[0036] A receiving device 50 is provided near the inner side of the storage device 10 to receive the container side wall 2 separated from the storage device 10. Figure 1 As shown, the receiving device 50 is composed of a side wall material taking frame 51 and a receiving portion 52. The side wall material taking frame 51 is a steel frame vertically arranged at a predetermined distance from the inner side of the storage device 10, and is used for the separated container side wall 2 to lean on it to be transferred. On the side of the side wall material taking frame 51 close to the storage device 10, a receiving portion 52 is horizontally arranged parallel to the upper surface of the bottom edge tooth chain 12 of the storage device 10, and under the premise of not affecting the rotation of the bottom edge tooth chain 12 around its own axis, the distance between the receiving portion 52 and the upper surface of the bottom edge tooth chain 12 in the direction perpendicular to the container side wall 2 is made as small as possible.

[0037] The stored container side wall 2 gradually moves to the inner edge of the storage device 10 as the top edge tooth chain 11 and the bottom edge tooth chain 12 rotate. When separation is required, the discharging device 40 applies a force toward the receiving device 50 to the upper part of the container side wall 2 near the top edge, so that the container side wall 2 falls toward the receiving device 50 and leans on the side wall material taking rack 51 of the receiving device 50. At the bottom edge of the container side wall 2, since the distance between the receiving part 52 of the receiving device 50 and the bottom edge tooth chain 12 is less than the thickness of the bottom edge of the container side wall 2, the bottom edge of the container side wall 2 moves to the receiving part 52 of the receiving device 50 as the bottom edge tooth chain 12 rotates. In this way, the container side wall 2 is completed from the storage state to the state to be transferred to the assembly platform. Preferably, the height of the side wall material picking rack 51 is set lower than the height of the lower surface of the top edge tooth chain 11 of the storage device 10, that is, lower than the top edge of the container side wall 2 in the storage device 10. Such a setting enables the top edge of the container side wall 2 to be in a free state when the container side wall 2 leans on the side wall material picking rack 51, which can facilitate the subsequent grabbing of the lifting device 60.

[0038] The lifting device 60 is disposed directly above the receiving device 50 and is used to lift the container side wall 2 located on the receiving device 50 to the final assembly platform for container assembly. Figure 2 The figure shows a schematic diagram of the structure of the lifting device 60 of the present invention. The main structure of the lifting device 60 is a rectangular hanger 61. Two grab hooks 62 are respectively arranged on both sides of the hanger 61 in the length direction, and the two grab hooks 62 on the same side are used to grab and fix the same container side wall 2. For convenience, the grab hooks 62 are arranged at both ends of the hanger 61 in the length direction.

[0039] In particular, each grab hook 62 is connected to the hanger 61 through its own retractable grab arm 63, and the grab arm 63 is controlled by a hydraulic station 64 disposed on the hanger 61 so that the length of the grab arm 63 can be retracted. In this way, the distance between the two grab hooks 62 located at the same end is adjustable, that is, the distance between the two container side walls 2 hoisted by the hoisting device 60 is adjustable. Due to various reasons, each time the two separated container side walls 2 lean on the receiving device 50, the distance between their two top edges is different and cannot be completely consistent. Therefore, by providing a grab hook 62 with an adjustable distance, the distance between the grab hooks 62 can be adjusted according to the actual distance between the top edges of the two container side walls 2, so as to achieve rapid grabbing of the container side walls 2 and improve the hoisting efficiency. On the other hand, when the lifting device 60 lifts the container side wall 2 to the assembly platform, the hydraulic station 64 can be controlled to adjust the distance between the grab hooks 62 through the grab arm 63 according to the width of the container to be assembled, that is, to adjust the width between the two container side walls 2 to adapt to the width of the container to be assembled, thereby saving the time of adjusting the position of the container side wall 2 after lifting it to the right place, and it is highly adaptable to non-standard containers, such as extra-wide containers or narrow containers, thereby improving the assembly efficiency of the container. Preferably, a locking cylinder 65 is also provided on each grab hook 62, so that the grab hook 62 remains locked when it grabs the container side wall 2, to prevent the grab hook 62 from loosening during the lifting process, causing the container side wall 2 to fall and cause safety problems.

[0040] Preferably, an operating platform 70 is further provided between the two receiving devices 50 to facilitate manual operation or maintenance of the container side wall storage and upper assembly system 1 .

[0041] It can be understood that for automation considerations, in the container side wall storage and upper assembly system shown in the present invention, the container side wall is transferred from the conveying device to the storage device and the container side wall is separated from the storage device by a pushing device and a discharging device respectively. In application, according to actual conditions, these two steps can also be completed manually or by other means.

[0042] The working process of the container side wall storage and upper assembly system 1 according to the present invention is introduced in detail below.

[0043] If the produced container side wall 2 does not need to be immediately involved in the container assembly, it should be stored first and then transferred to the final assembly platform when it is needed to participate in the assembly. At this time, the container side wall 2 needs to be transferred from the production station to the conveying device 20 by a crane or other tools and transferred to the storage device 10 by the conveying device 20. During this transfer process, the container side wall 2 leans on the conveying wall 22 of the conveying device 20 in a roughly inclined state. When the container side wall 2 reaches the end of the conveying device 20, the conveying device 20 remains stopped, and the pushing device 30 and the storage device 10 act simultaneously. The upper pushing cylinder 31 acts on the upper middle part of the container side wall 2 to apply a force toward the storage device 10, and the lower pushing cylinder 32 acts on the position near the bottom of the container side wall 2 to apply a force toward the storage device 10, so that the container side wall 2 is transferred from the conveying device 20 to the storage device 10 and the container side wall 2 is adjusted from the roughly inclined state to the vertical state for storage. When the container side wall 2 is pushed to the storage device 10 by the pushing device 30 , the top and bottom edges of the container side wall 2 abut against the side surfaces of the teeth of the lower surface of the top toothed chain 11 and the upper surface of the bottom toothed chain 12 , respectively. At this time, the top toothed chain 11 and the bottom toothed chain 12 rotate around their respective axes, so that the lower surface of the top toothed chain 11 and the upper surface of the bottom toothed chain 12 move toward the inner side of the storage device 10, and the container side wall 2 also moves toward the inner side of the storage device 10 under the thrust of the pushing device 30. After moving a predetermined distance, the top and bottom sides of the container side wall 2 facing the conveying device 20 also abut against the side surfaces of the teeth of the lower surface of the top toothed chain 11 and the upper surface of the bottom toothed chain 12. At this time, the top and bottom sides of the container side wall 2 are respectively clamped and fixed by the tooth grooves of the lower surface of the top toothed chain 11 and the upper surface of the bottom toothed chain 12, and the pushing device 30 stops moving and retracts, thereby completing the storage of the container side wall 2 in a vertical state on the storage device 10.

[0044] When the stored container side wall 2 needs to be transported to the final assembly platform for container assembly, the stored container side wall 2 should first be separated from the storage device 10 to the receiving device 50, and then lifted by the lifting device 60 to the final assembly platform for assembly.

[0045] Specifically, the stored container side wall 2 moves to the inner edge of the storage device 10 as the top edge tooth chain 11 and the bottom edge tooth chain 12 rotate around their respective axes. At this time, the cylinder of the unloading device 40 is activated, and a force toward the receiving device 50 is applied to the upper part of the container side wall 2 near the top edge. The top edge of the container side wall 2 is separated from the top edge tooth chain 11 and finally leans on the side wall material rack 51 of the receiving device 50. At this time, the cylinder of the unloading device 40 can stop moving and retract. The bottom edge of the container side wall 2 moves to the receiving portion 52 of the receiving device 50 as the bottom edge tooth chain 12 rotates. In this way, the container side wall 2 is separated from the storage device 10 and leans on the receiving device 50 in an inclined state. Then the lifting device 60 is activated. First, the lifting device 60 is lowered to a position where the grab hook 62 can grab the top edge of the container side wall 2. The hydraulic station 64 is controlled to adjust the length of the grab arm 63 according to the distance between the top edges of the two container side walls 2 so that the grab hook 62 can grab the top edges of the two container side walls 2 respectively, and the grab hook 62 is controlled to grab the top edge of the container side wall 2. At this time, the locking cylinder 65 is activated to keep the grab hook 62 in a gripping state to prevent it from loosening. Then the lifting device 60 is controlled to lift the two container side walls 2 to the final assembly platform to participate in the assembly of the container. During the lifting process, the distance between the two container side walls 2 can also be adjusted to adapt to the width of the container to be assembled. In this way, the final assembly process on the container side wall is completed.

[0046] The container side wall storage and assembly system according to the present invention can realize automatic storage and automatic assembly of container side walls, has a very high degree of automation, greatly saves the use of manpower, and improves safety. Storing the container side walls in a vertical position can effectively avoid deformation of the container side walls and other factors that are not conducive to assembly, thereby ensuring the production quality of container products. The container side walls are transported using an adjustable sling, so that the distance between the two container side walls can be adjusted during the lifting process, saving adjustment time during assembly and improving production efficiency.

[0047] The present invention has been described by the above embodiments, but it should be understood that the above embodiments are only for the purpose of example and illustration, and are not intended to limit the present invention to the described embodiments. It can be understood by those skilled in the art that more variations and modifications can be made according to the teachings of the present invention, and these variations and modifications all fall within the scope of the protection claimed by the present invention.
