Description

Technical Field

[0001] This application belongs to the field of container manufacturing technology, specifically relating to a storage and conveying device. Background Technology

[0002] Container production requires high daily output and a fast production cycle, especially on the final assembly line, where the flow of complete containers affects the overall production efficiency. The bottleneck of the assembly line lies in the assembly fixtures, so solving the storage and transfer of components is crucial. Underframe storage typically involves stacking them on a storage platform, then using a crane to lift each underframe onto a traversing trolley, and finally transporting it to the assembly fixture for assembly with side panels, top covers, and other structural components. This method occupies a large amount of space. Summary of the Invention

[0003] To address the technical problem of large space occupation during container rack transfer, this application provides a storage and conveying device.

[0004] This application provides a storage and conveying device for storing and conveying multiple container racks stacked sequentially along their height. The top of each rack has notches on both sides along its width for mounting side panels of containers. These notches extend along the length of the rack. The storage and conveying device includes a storage and conveying unit, which comprises:

[0005] The support frame has a first space and a second space arranged sequentially from top to bottom;

[0006] A conveying mechanism for conveying the base frame, located in the second space;

[0007] The lifting mechanism includes a lifting platform that reciprocates along the height direction to support the base frame switching between a first space and a second space;

[0008] A telescopic mechanism is installed on the bracket. Multiple telescopic mechanisms are respectively provided on both sides of the base frame in the width direction. Multiple telescopic mechanisms located on the same side are arranged sequentially along the length direction of the base frame. The telescopic mechanism includes a telescopic member. The telescopic member has a telescopic end that reciprocates along the width direction of the base frame to extend into the first space and support multiple base frames.

[0009] In some embodiments, the telescopic mechanism further includes a support plate and a slide rail mounted on the bracket, the slide rail being located outside the first space, the support plate being slidably connected to the slide rail, and the telescopic end of the telescopic member being connected to the support plate so that the support plate extends into the first space.

[0010] In some embodiments, the slide rail is provided with a groove that extends through the width of the base frame and has its opening facing upwards. The width of the groove opening is smaller than the width of the groove bottom.

[0011] In some embodiments, when the telescopic end of the telescopic member leaves the first space, the projection of the telescopic mechanism along the height direction is located outside the lifting platform; or,

[0012] The lifting platform is provided with a clearance for avoiding the telescopic mechanism.

[0013] In some embodiments, the support includes connecting rods and columns of the same number as the telescopic mechanism, with each column corresponding to a telescopic mechanism. The fixed end of the telescopic component is installed on the corresponding column. Among the multiple columns located on the same side of the base frame, adjacent columns are connected by the connecting rods, and the portions of the multiple columns whose height is lower than that of the telescopic mechanism enclose the second space.

[0014] In some embodiments, the bracket further includes a plurality of stops, which are spaced apart and installed on the column and / or the connecting rod, and the plurality of stops together form the first space.

[0015] In some embodiments, the conveying direction of the conveying mechanism is parallel to the length direction of the base frame.

[0016] In some embodiments, the conveying mechanism is a chain conveying mechanism, wherein the upper layer of the chain is slidably disposed on the upper surface of the lifting platform, and the lower layer of the chain is located below the lifting platform.

[0017] In some embodiments, the lifting mechanism includes a scissor lift platform, the output end of which is connected to the lifting platform.

[0018] In some embodiments, there are multiple storage and conveying units, which are arranged sequentially along the length of the base frame.

[0019] According to the storage and conveying device provided in the embodiments of this application, multiple base frames stacked along the height direction are stored by relying on the first space of the bracket, the base frames are alternately supported by the lifting mechanism and the telescopic mechanism, and the base frames are output sequentially from bottom to top in cooperation with the conveying mechanism.

[0020] Because the storage and conveying device of this application integrates top-to-bottom storage and conveying functions, both functions can be completed in a single workstation. This results in a more compact structure, occupies less space, and solves the problem of limited storage space. Furthermore, it eliminates the need for crane lifting operations, and the automated mechanical conveying frame increases efficiency.

[0021] This application utilizes the notch in the mounting side plate of the base frame itself to provide clearance space for the telescopic component to extend to the bottom of the lower base frame among two adjacent base frames, avoiding interference between the lower base frame and the telescopic component. No additional clearance structure is required, making it more convenient. Attached Figure Description

Detailed Implementation

[0029] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] According to a first aspect of this application, a storage and conveying device is provided, which realizes the storage and conveying of multiple container racks, reduces space occupation, and is highly efficient.

[0031] This application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Please see Figure 1The container's underframe 100 provides a supporting base for the container's side panels and top cover. Notches 110 are provided on both sides of the top of the underframe 100 along its width direction, and these notches 110 extend through the underframe 100 along its length direction. These notches 110 can be used to install the side panels. Therefore, when multiple underframes 100 are stacked sequentially along their height direction, a through groove 101 extending along the length direction is formed between two adjacent side panels.

[0033] Please see Figure 2 , Figure 3 as well as Figure 4 The storage and conveying device provided in this application embodiment includes a storage and conveying unit 200, which includes a support 210, a conveying mechanism 240, a lifting mechanism 230, and a telescopic mechanism 220. Wherein:

[0034] Please see Figure 4 The support frame 210 has a first space 214 and a second space 215 arranged sequentially from top to bottom. That is, the first space 214 is on top and the second space 215 is on the bottom. Under storage conditions, multiple base frames 100 can be stored in the second space 215.

[0035] The conveying mechanism 240 is used to provide power for the lowermost base frame 100 to move from the second space 215 to the assembly position, thereby moving the base frame 100 from the second space 215 to the assembly position and realizing the position transfer of the base frame 100.

[0036] The lifting mechanism 230 includes a lifting platform 231 that reciprocates along the height direction to support the base frame 100 to switch between the first space 214 and the second space 215. That is, the base frame 100 can move downward from the first space 214 to the second space 215, or it can move upward from the second space 215 to the first space 214.

[0037] Telescopic mechanisms 220 are mounted on brackets 210. Multiple telescopic mechanisms 220 are provided on both sides of the base frame 100 in the width direction. These mechanisms, located on the same side, are arranged sequentially along the length of the base frame 100. Each telescopic mechanism 220 includes a telescopic member 221, which has a telescopic end that reciprocates along the width direction of the base frame 100, extending into the first space 214 to support multiple base frames 100. Thus, the multiple telescopic members 221 can temporarily support all the upper base frames 100 except the lowest one, allowing the lowest base frame 100 to move down from the first space 214 to the second space 215 with the lifting platform 231 and be conveyed out by the conveying mechanism 240. The multiple telescopic mechanisms 220 on both sides of the base frame 100 in the width direction improve the stability and safety of the telescopic members 221 supporting the multiple base frames 100.

[0038] When the storage and conveying device is in operation, the lifting platform 231 of the lifting mechanism 230 provides support for multiple base frames 100 stacked sequentially along the height direction. Upon receiving a conveying signal, the lifting platform 231 rises, driving all the base frames 100 to rise until the height of the notch 110 of the first base frame 100 is level with the height of the telescopic member 221. The telescopic end of the telescopic member 221 extends into the first space 214 and enters the notch 110 of the first base frame 100 from bottom to top, fitting against the bottom of the second base frame 100. The notch 110 of the mounting side plate of the base frame 100 avoids the telescopic end of the telescopic member 221, so that the bottommost base frame 100 and the telescopic member 221 will not interfere with each other. After the telescopic end of the telescopic component 221 extends into the bottom of the second base frame 100, the lifting mechanism 230 lowers the lifting platform 231 and the first base frame 100 into the second space 215. Then, the descent stops, and the conveying mechanism 240 moves the first base frame 100 along its length to the assembly position. The lifting mechanism 230 then raises the lifting platform 231 to the first space 214, supporting all the remaining base frames 100. The telescopic component 221 retracts, switching the support of the base frame 100 from the telescopic component 221 to the lifting platform 231. The lifting platform 231 descends, lowering all the remaining base frames 100, completing the transport of one base frame 100. Repeating the above steps allows for the transport of the remaining base frames 100.

[0039] In some embodiments, please refer to Figure 3 The support frame 210 includes connecting rods 212 and the same number of uprights 211 as the telescopic mechanisms 220. Each upright 211 corresponds to one telescopic mechanism 220. The fixed end of the telescopic component 221 is installed on the corresponding upright 211. Among the multiple uprights 211 located on the same side of the base frame 100, adjacent uprights 211 are connected by connecting rods 212. The portions of the multiple uprights 211 whose height is lower than that of the telescopic mechanisms 220 enclose a second space 215. The design of the uprights 211 makes the structure of the support frame 210 simpler and provides an installation foundation for each telescopic mechanism 220. The connecting rods 212 improve the stability of each upright 211 and reduce the risk of swaying. The connection between the connecting rods 212 and the uprights 211 can be welded or screwed, depending on the strength of the connection between the connecting rods 212 and the uprights 211. In other embodiments, the support 210 may also be a frame structure, with the lower part of the frame structure enclosing a second space 215 and the upper part of the frame structure enclosing a first space 214.

[0040] In some embodiments, please refer to Figure 4The bracket 210 also includes multiple stop bars 213, which are spaced apart and installed on the column 211 and / or connecting rod 212, forming a first space 214. The stop bars 213 prevent the base frame 100 from moving along the width direction. The stop bars 213 can be welded to the column 211 or screwed together. Of course, when the stop bars 213 are connected to the connecting rod 212, they can be either welded or screwed together.

[0041] In some embodiments, the telescopic mechanism 220 further includes a support plate 222, and the telescopic end of the telescopic member 221 is connected to the support plate 222 so that the support plate 222 extends into the first space 214. By temporarily supporting the base frame 100 with the support plate 222, the effective area between the telescopic mechanism 220 and the base frame 100 is increased, thereby ensuring the storage stability and safety of multiple base frames 100. In other embodiments, the telescopic end of the telescopic member 221 can also directly support the base frame 100 after extending into the first space 214.

[0042] When the telescopic mechanism 220 includes a support plate 222, the support plate 222 can be horizontally arranged, and the entire upper surface of the support plate 222 forms a surface contact with the base frame 100, thus increasing the effective area. In other embodiments, the support plate 222 can also be replaced by a support block, which can also support multiple base frames 100, thus providing temporary support for the base frames 100.

[0043] In some embodiments, the telescopic mechanism 220 further includes a slide rail 223 mounted on the bracket 210. The slide rail 223 is located outside the first space 214, and the support plate 222 is slidably connected to the slide rail 223 to improve the stability of the support plate 222 reciprocating along the width direction of the base frame 100.

[0044] In some embodiments, the slide rail 223 is provided with a groove that extends through the width of the base frame 100, with the groove opening facing upwards. The support plate 222 is slidably disposed within the groove, and the telescopic end of the telescopic member 221 is located above the groove. When the slide rail 223 is provided with a groove, the width of the groove opening is smaller than the width of the bottom of the groove, to further improve the stability of the support plate 222 reciprocating along the width of the base frame 100. In other embodiments, the support plate 222 is provided with a groove, and the slide rail 223 is slidably disposed within the groove.

[0045] In some embodiments, the base frame 100 is provided with two telescopic mechanisms 220 on each side along the width direction, which can ensure the stability and safety of temporary support for multiple base frames 100, while also ensuring low cost. In other embodiments, three or four telescopic mechanisms 220 may also be provided on each side along the width direction of the base frame 100, which can also achieve temporary support for multiple base frames 100.

[0046] In some embodiments, please refer to Figure 3 When the telescopic end of the telescopic member 221 leaves the first space 214, the projection of the telescopic mechanism 220 along the height direction is located outside the lifting platform 231 to avoid interference between the telescopic mechanism 220 and the lifting platform 231. In other embodiments, the lifting platform 231 is provided with a clearance notch 110 to avoid the telescopic mechanism 220. During the lifting process of the lifting platform 231, the telescopic mechanism 220 can pass through the clearance notch 110 to avoid friction between the lifting platform 231 and the lifting mechanism 230.

[0047] In some embodiments, the telescopic component 221 can be a hydraulic cylinder, providing stable telescopic force and better support stability. The telescopic end of the telescopic component 221 can be welded to the support plate 222, resulting in high connection strength and good stability.

[0048] The lifting mechanism 230 serves as the structure for lowering the base frame 100. The lifting platform 231 can be a lifting plate or a lifting frame. For example, the lifting frame includes two longitudinal beams 2312 and multiple transverse beams 2311. The multiple transverse beams 2311 are arranged sequentially along the axial direction of the longitudinal beams 2312, and both ends of each transverse beam 2311 are connected to the two longitudinal beams 2312 respectively, forming a lifting platform 231 of the lifting frame type. The lifting frame can be a frame structure welded from profiles. The transverse beams 2311 serve to strengthen the fixing function and can also be fixed with bolts.

[0049] In some embodiments, the lifting mechanism 230 includes a scissor lift platform 232, the output end of which is connected to the lifting platform 231, thereby improving the stability of the lifting platform 231 during the lifting process. The scissor lift platform 232 is chosen as the lifting drive structure for the lifting platform 231 because it offers good lifting stability and is readily available. The output end of the scissor lift platform 232 can be an output plate, which is welded to the crossbeam 2311 of the lifting frame. The scissor lift platform 232 can be constructed using profiles and steel plates welded together, with the lifting action hydraulically performed.

[0050] In other embodiments, the lifting mechanism 230 can also be implemented using hydraulic cylinders. For example, multiple hydraulic cylinders can be provided, arranged at intervals, and reciprocating in the height direction. The extension and retraction ends of the hydraulic cylinders are all connected to the lifting platform 231, which can also realize the lifting of the lifting platform 231.

[0051] In some embodiments, the conveying direction of the conveying mechanism 240 is parallel to the length direction of the base frame 100, causing the base frame 100 to move along its own length. It should be noted that parallelism between the conveying direction and the length direction of the base frame 100 means that the two directions are approximately the same, but there may also be a small angular deviation.

[0052] In some embodiments, please refer to Figure 3The conveying mechanism 240 is a chain conveying mechanism 240. The upper layer of the chain is slidably disposed on the upper surface of the lifting platform 231, and the lower layer of the chain is located below the lifting platform 231. That is to say, the lifting platform 231 will lift and lower together with the conveying mechanism 240 during the lifting process. Of course, in some other embodiments, the chain conveying mechanism 240 and the lifting platform 231 can also be set separately. There are two chain conveying mechanisms 240, located on both sides of the width direction of the lifting platform 231 respectively. After the lifting platform 231 lowers with the base frame 100, the base frame 100 is changed from being supported by the lifting platform 231 to being supported by the chain, and then is conveyed to the assembly position by the chain conveying mechanism 240.

[0053] Please see Figure 3 The chain conveyor mechanism 240 includes a drive motor 243, a first chain, a second chain 244, a first sprocket 241, and a second sprocket 242. Two first sprockets 241 and two second sprockets 242 are provided and rotatably mounted on the longitudinal beam 2312. One first sprocket 241 is coaxially connected to one second sprocket 242, and the other first sprocket 241 is coaxially connected to the other second sprocket 242. Both the first chain and the second chain 244 are annular. The first chain meshes with the two first sprockets 241, and the second chain 244 meshes with the two second sprockets 242. The drive motor 243 is connected to either the first sprocket 241 or the second sprocket 242 for transmission. The chain conveyor mechanism 240 is prior art; further details can be found in existing art disclosures, and will not be elaborated upon here.

[0054] In some embodiments, the longitudinal beam 2312 is further provided with a tensioning structure for adjusting the tension of the first chain and the second chain 244, and the tensioning mechanism and the drive motor 243 are located at both ends of the longitudinal beam 2312 respectively.

[0055] In some embodiments, please refer to Figure 3 Multiple storage and conveying units 200 are provided, and these units are arranged sequentially along the length of the base frame 100. In other words, by providing multiple base frames 100 storage structures, the storage capacity of the base frame 100 is increased. Since the multiple storage and conveying units 200 are arranged sequentially along the length of the base frame 100, the base frame 100 of the most end storage and conveying unit 200 can be conveyed sequentially by the conveying mechanism 240 of the multiple storage and conveying units 200.

[0056] The storage and conveying device provided in this application allows the stacking height of the base frames 100 to not exceed the maximum load of the lifting platform 231. Generally, it is advisable to stack five base frames 100. When the five base frames 100 are in storage, they are supported by the lifting platform 231. The process of conveying the base frames 100 from bottom to top is as follows: The lifting platform 231 descends so that the notch 110 of the first base frame 100 from the bottom is level with the height of the support plate 222. The telescopic component 221 is activated, and the support plate 222 extends into the notch 110 of the first base frame 100 and presses against the four base frames 100 on the upper layer to stably support the four base frames 100. Then the lifting platform 231 descends, and the drive motor 243 is activated. The chain drives the first base frame 100 to be transported into the assembly position. The lifting platform 231 rises to support the second base frame 100, the support plate 222 retracts to the outside of the first space 214 along with the telescopic component 221, and the lifting platform 231 descends with the remaining four base frames 100 to complete the conveying operation of one base frame 100.

It ensures a continuous production process, integrates storage and conveying, and greatly improves production efficiency and solves the problem of storage space.
