Abstract
Description
Technical Field
[0001] This utility model relates to the field of logistics transportation technology, and in particular to a conveying device and conveying system. Background Technology
[0002] In the field of logistics and transportation technology, with the increasing use of containerized containers, the requirements for cross-floor conveying devices are also becoming more stringent. Existing technologies employ continuous elevators and reciprocating elevators for cross-floor container transport. However, for irregular containers (such as cage carts), only reciprocating elevators can be used. The limitations of the reciprocating elevator's structure and conveying method result in relatively low conveying efficiency for irregular containers. Utility Model Content
[0003] The main purpose of this utility model is to propose a conveying device and conveying system, which aims to solve the technical problem of low conveying efficiency of irregular containers.
[0004] To achieve the above objectives, a first aspect of this utility model provides a conveying device for vertically conveying a container, the container including a carrying plate and supporting legs, the supporting legs being connected to the carrying plate and protruding from the bottom side of the carrying plate, the conveying device comprising:
[0005] A base frame encloses a conveying space. The base frame includes an input port and an output port that communicate with the conveying space. The input port and the output port are arranged at intervals along the vertical direction. The input port is used for the container to enter the conveying space, and the output port is used for the container to exit the conveying space.
[0006] At least two chain plates are movably connected to the base frame. The chain plates are adapted to abut against the bottom side of the loading plate and are arranged laterally spaced from the legs to support the container.
[0007] A first driving unit is used to drive each of the chain plates to move along the vertical direction, so as to transport the container from the input port to the output port;
[0008] During the movement of one of the chain plates along the vertical direction from the input port to the output port, the other chain plate moves in the opposite direction along the vertical direction from the output port to the input port to continuously transport the container.
[0009] In some embodiments, the support legs include a first support and a second support arranged laterally at intervals, wherein the first support and the second support are located on opposite sides of the chain plate along the lateral direction during the process of the chain plate carrying the container.
[0010] In some embodiments, the chain plate includes a chain structure and a plurality of spaced-apart support blocks, the chain structure connecting each of the support blocks, the support blocks collectively defining a bearing surface adapted to abut against the bottom side of the carrier plate to support the container.
[0011] In some embodiments, the chain plate has a first axis perpendicular to its bearing surface, wherein during the movement of the first chain plate from the input port toward the output port along the vertical direction, the first axis of the first chain plate is parallel to the vertical direction; and during the movement of the second chain plate from the output port toward the input port in the opposite direction of the vertical direction, the first axis of the second chain plate is perpendicular to the vertical direction.
[0012] In some embodiments, the chain plate includes a limiting block connected to the chain structure. During the process of the support block abutting against the bottom side of the carrier plate, the limiting block is located on one side of the carrier plate in the lateral direction and protrudes from the top side of the carrier plate to restrict the container from moving in the lateral direction.
[0013] In some embodiments, the base frame is provided with a first guide rail extending vertically, and the chain plate is adapted to slide vertically on the first guide rail to transport the container from the input port to the output port.
[0014] A second aspect of this utility model provides a conveying system for conveying the container, the conveying system comprising:
[0015] The conveying device as described in the above embodiments;
[0016] An input segment, connected to the input port, for conveying the container on the input segment to the input port; and,
[0017] An output section, connected to the output port, is used to transport the container from the output port to the output section.
[0018] In some embodiments, the input segment includes a first guide portion and a second drive portion. The first guide portion is adapted to abut against the bottom side of the carrier plate and is arranged laterally with respect to the support leg to carry the container. The second drive portion is adapted to drive the container to move laterally to transport the container from the input segment to the input port.
[0019] In some embodiments, the output section includes a second guide portion and a third drive portion. The second guide portion is adapted to abut against the bottom side of the carrier plate and is arranged laterally with respect to the support leg to carry the container. The third drive portion is adapted to drive the container to move laterally to convey the container from the output port to the output section.
[0020] In some embodiments, the input segment is provided with a second guide rail, which extends laterally, and the legs are adapted to slide along the second guide rail as the container moves along the input segment toward the input port.
[0021] And / or,
[0022] The output section is provided with a third guide rail, which extends laterally. As the container moves away from the output port along the output section, the support leg is adapted to slide along the third guide rail.
[0023] Compared with the prior art, the beneficial effects of this utility model include:
[0024] In the technical solution of this utility model, the conveying device is used to vertically convey containers. The container includes a carrying plate and supporting legs, with the supporting legs connected to the carrying plate and protruding from the bottom side of the carrying plate. The conveying device includes a base frame, at least two chain plates, and a first drive unit. The base frame encloses a conveying space and includes an inlet and an outlet communicating with the conveying space. The inlet and outlet are arranged vertically at intervals. The inlet is used for the container to enter the conveying space, and the outlet is used for the container to exit the conveying space. In the prior art, reciprocating elevators are used to convey irregular containers across floors. Due to the limitations of the structure and conveying method of the reciprocating elevator, the conveying efficiency of the containers is relatively low. In this solution, while one chain plate moves vertically from the inlet to the outlet, the other chain plate moves vertically in the opposite direction from the outlet to the inlet, thus enabling continuous conveying of containers and effectively improving the conveying efficiency of the containers. Furthermore, during the process of the chain plate carrying the container, the chain plate is adapted to abut against the bottom side of the carrying plate and is arranged laterally at intervals with the support legs. This increases the contact area between the container and the chain plate, preventing the container from swaying significantly relative to the chain plate due to the support legs abutting against it, thus preventing the container from tipping over and effectively improving the stability of container transport. In addition, the chain plate is movably connected to the base frame, and the first drive unit can drive the chain plate to move vertically to transport the container from the inlet to the outlet, ensuring convenient container transport.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0041] The first aspect of this utility model provides a conveying device 10 for vertically conveying a container 20, which can effectively improve the conveying efficiency of the container 20. It should be noted that the container 20 can be a regular container (such as a hopper) or an irregular container (such as a cage cart). This embodiment uses an irregular container 20 as an example for description. The irregular container 20 includes a carrying plate 201 and a support leg 202. The support leg 202 is connected to the carrying plate 201 and protrudes from the bottom side of the carrying plate 201. It can be understood that the support leg 202 can be a pillar or a wheel. This embodiment uses a wheel as an example for description. The following refers to... Figures 1 to 3 The conveying device 10 of the present application embodiment is described below. Specifically, the conveying device 10 includes a base frame 100, at least two chain plates 200 and a first drive unit 300.
[0042] Reference Figure 1 The base frame 100 encloses a conveying space 110, which is used to convey the container 20. It is understood that the base frame 100 can be a closed space or an open space; this embodiment uses an open space as an example. The base frame 100 includes an inlet 120 and an outlet 130, both of which are connected to the conveying space 110. The inlet 120 allows the container 20 to enter the conveying space 110, and the outlet 130 allows the container 20 to exit the conveying space 110.
[0043] Reference Figure 1 The input port 120 and the output port 130 are arranged vertically at intervals. In some embodiments, the input port 120 may be located on the lower side of the base frame 100, and the output port 130 may be located on the upper side of the base frame 100, that is, the conveying device 10 can realize the lifting operation of the container 20. In other embodiments, the input port 120 may be located on the upper side of the base frame 100, and the output port 130 may be located on the lower side of the base frame 100, that is, the conveying device 10 can realize the lowering operation of the container 20. It should be noted that in some embodiments, the input port 120 and the output port 130 may be located on the same side of the base frame 100 in the transverse direction. In other embodiments, the input port 120 and the output port 130 may be located on opposite sides of the base frame 100 in the transverse direction. This application embodiment is described using the example of the output port 130 being located on the upper side of the input port 120, and the output port 130 and the input port 120 being located on opposite sides of the base frame 100 in the transverse direction.
[0044] Reference Figure 1The chain plate 200 is used to support the container 20. It is understood that two, three, or five chain plates 200 can be provided; this embodiment uses three chain plates 200 as an example for explanation. The chain plate 200 is movably connected to the base frame 100. During the process of the chain plate 200 supporting the container 20, the chain plate 200 can abut against the bottom side of the carrying plate 201 of the container 20, and the chain plate 200 and the support legs 202 are arranged laterally at intervals, which can improve the stability of the chain plate 200 supporting the container 20.
[0045] The first drive unit 300 is used to drive the chain plate 200 to move vertically, as shown in the reference. Figure 1 In terms of orientation, the first drive unit 300 can drive the chain plate 200 to move vertically to transport the container 20 from the input port 120 to the output port 130, thereby adjusting the height of the container 20. Specifically, while one chain plate 200 moves vertically from the input port 120 to the output port 130, the other chain plate 200 can move vertically in the opposite direction from the output port 130 to the input port 120, thus enabling continuous transport of the container 20.
[0046] In the technical solution of this utility model, the conveying device 10 is used to vertically convey a container 20. The container 20 includes a carrying plate 201 and a support leg 202. The support leg 202 is connected to the carrying plate 201 and protrudes from the bottom side of the carrying plate 201. The conveying device 10 includes a base frame 100, at least two chain plates 200, and a first drive unit 300. The base frame 100 encloses a conveying space 110 and includes an input port 120 and an output port 130 communicating with the conveying space 110. The input port 120 and the output port 130 are arranged vertically at intervals. The input port 120 is used for the container 20 to enter the conveying space 110, and the output port 130 is used for the container 20 to exit the conveying space 110. In the prior art, reciprocating hoists are used to convey irregular containers across floors. However, due to the limitations of the structure and conveying method of the reciprocating hoist, the conveying efficiency of the containers is relatively low. In this design, while one chain plate 200 moves vertically from the input port 120 to the output port 130, another chain plate 200 moves vertically in the opposite direction from the output port 130 to the input port 120. This allows for continuous transport of the container 20, effectively improving its transport efficiency. Furthermore, during the transport of the container 200, the chain plate 200 is adapted to abut against the bottom side of the carrying plate 201 and is laterally spaced from the support legs 202. This increases the contact area between the container 20 and the chain plate 200, preventing significant swaying of the container 20 relative to the chain plate 200 due to the support legs 202 contacting the chain plate 200, thus preventing the container 20 from tipping over and effectively improving the stability of the transport. Additionally, the chain plate 200 is movably connected to the base frame 100, and the first drive unit 300 can drive the chain plate 200 to move vertically to transport the container 20 from the input port 120 to the output port 130, ensuring convenient transport of the container 20.
[0047] Reference Figures 1 to 3 The following describes the specific load-bearing operation of the chain plate 200 on the container 20. In some embodiments, the support leg 202 includes a first support 2021 and a second support 2022, which are arranged laterally at intervals, as shown in the figure. Figure 3 In terms of orientation, the first branch 2021 and the second branch 2022 can be arranged at intervals in the left-right direction. During the process of the chain plate 200 carrying the container 20, the first branch 2021 and the second branch 2022 are located on opposite sides of the chain plate 200 in the lateral direction. That is, the first branch 2021 and the second branch 2022 can limit the container 20, effectively suppress the container 20 from moving too much in the lateral direction relative to the chain plate 200, improve the stability of the chain plate 200 carrying the container 20, and realize reliable transportation of the container 20.
[0048] Reference Figure 2 The specific structure of the chain plate 200 is described below. In some embodiments, the chain plate 200 includes a chain structure 210 and a plurality of spaced-apart support blocks 220, each support block 220 having the same structure. The chain structure 210 connects each support block 220. Each support block 220 can collectively define a bearing surface 230, which can abut against the bottom side of the carrying plate 201 to support the container 20. Compared to a solution where a single support plate supports the container, the chain structure 210 of this solution connects each support block 220, and multiple support blocks 220 jointly support the container 20, thus achieving flexible support for the container 20 and adapting to various bottom structures of the container 20, expanding the application range of the conveying device 10.
[0049] Reference Figure 1 and Figure 2 The specific conveying configuration of the chain plate 200 is described below. In some embodiments, to facilitate description and understanding of the different states of the chain plate 200 during vertical movement, the chain plate 200 is defined to have a first axis 231 perpendicular to its bearing surface 230. (Refer to...) Figure 1 In terms of orientation, as the first chain plate 200 moves vertically from the input port 120 towards the output port 130, the first axis 231 of the first chain plate 200 is parallel to the vertical direction. That is, the chain plate 200 is horizontally arranged as a whole under load, which ensures the stability of the container 20's transport. (Refer to...) Figure 1 In terms of orientation, during the process of the second chain plate 200 moving in the opposite direction from the output port 130 to the input port 120 in the vertical direction, the first axis 231 of the second chain plate 200 is perpendicular to the vertical direction. That is, the chain plate 200 is arranged in a side-mounted manner when unloaded. Compared with the scheme where the chain plate is arranged horizontally when unloaded, it can effectively reduce the space occupied by the conveying device 10 in the horizontal direction and expand the application range of the conveying device 10.
[0050] The specific reversing motion configuration of the chain plate 200 is described below. In some embodiments, when the chain plate 200 switches from vertical to vertical reverse motion, the chain structure 210 can be bent relative to the base frame 100 to drive each support block 220 to move along a loop, thereby realizing the reversing motion of the chain plate 200. In other embodiments, when the chain plate 200 switches from vertical reverse motion to vertical motion, the chain structure 210 can also be bent relative to the base frame 100 to drive each support block 220 to move along a loop, thereby realizing the reversing motion of the chain plate 200. The chain plate 200 of this solution, with the above configuration, can improve the conveying efficiency of the container 20 and reduce the space occupied by the conveying device 10 in the lateral direction.
[0051] The specific limiting settings of the chain plate 200 for the container 20 are described below. In some embodiments, the chain plate 200 includes a limiting block connected to the chain structure 210. During the process of the support block 220 abutting against the bottom side of the carrying plate 201, the limiting block can be located on one side of the carrying plate 201 along the lateral direction and protrude from the top side of the carrying plate 201 to restrict the lateral movement of the container 20. In other embodiments, there can be two limiting blocks, which can be arranged laterally at intervals. During the process of the chain plate 200 carrying the container 20, the two limiting blocks, together with the support block 220, can form a U-shaped structure to carry and limit the container 20. The limiting blocks in this solution can limit the container 20, effectively improving the stability and reliability of the chain plate 200 carrying the container 20.
[0052] Reference Figure 1 The specific cooperation arrangement between the chain plate 200 and the base frame 100 is described below. In some embodiments, the base frame 100 is provided with a first guide rail 140, which is used for the chain plate 200 to move vertically. The first guide rail 140 can extend vertically. It can be understood that the base frame 100 can be provided with multiple first guide rails 140, and adjacent first guide rails 140 can be arranged at intervals. This embodiment of the application uses four first guide rails 140 as an example for explanation. The chain plate 200 can slide vertically on the first guide rail 140 to transport the container 20 from the input port 120 to the output port 130, realizing the vertical transport of the container 20. The first guide rail 140 can ensure the stability and reliability of the movement of the chain plate 200.
[0053] Reference Figure 1The second aspect of this utility model provides a conveying system 1 for conveying a container 20. The conveying system 1 includes a conveying device 10, an input section 30, and an output section 40 as described in the previous embodiment. The input section 30 is connected to an input port 120 to convey the container 20 on the input section 30 to the input port 120. Referring to orientation 1, the input section 30 can be located on the lower left side of the conveying device 10. The output section 40 is connected to an output port 130 to convey the container 20 from the output port 130 to the output section 40. Referring to orientation 1, the output section 40 can be located on the upper right side of the conveying device 10. The specific layout and relative position of the input section 30 and the output section 40 relative to the conveying device 10 can be determined according to actual conditions.
[0054] The conveying system 1 of this solution can continuously convey the container 20, effectively improving the conveying efficiency of the container 20. Furthermore, during the process of the chain plate 200 carrying the container 20, the chain plate 200 is adapted to abut against the bottom side of the carrying plate 201 and is arranged laterally spaced from the support legs 202. This increases the contact area between the container 20 and the chain plate 200, preventing the support legs 202 from abutting against the chain plate 200 and causing the container 20 to sway significantly relative to the chain plate 200, thus preventing the container 20 from tipping over and effectively improving the stability of the container 20's conveying. In addition, the chain plate 200 is movably connected to the base frame 100, and the first drive unit 300 can drive the chain plate 200 to move vertically to convey the container 20 from the input port 120 to the output port 130, ensuring convenient conveying of the container 20.
[0055] Reference Figure 1 The specific configuration of the input segment 30 is described below. In some embodiments, the input segment 30 includes a first guide portion 301, which is used to guide the container 20. It is understood that multiple first guide portions 301 can be provided. This embodiment of the application takes the provision of two first guide portions 301 as an example for explanation. The two first guide portions 301 can be arranged laterally at a distance perpendicular to the conveying direction of the input segment 30. Specifically, during the process of conveying the container 20 by the input segment 30, the first guide portion 301 can abut against the bottom side of the carrying plate 201 and be arranged laterally at a distance from the support leg 202. This can increase the contact area between the container 20 and the input segment 30, avoiding the situation where the support leg 202 directly abuts against the input segment 30, causing the container 20 to shake significantly relative to the input segment 30, and effectively improving the stability of the container 20's conveying. In addition, the input segment 30 is also provided with a second drive portion 302, which is used to drive the container 20 to move laterally, so as to convey the container 20 from the input segment 30 to the input port 120, ensuring the conveying efficiency and conveying stability of the container 20. Specifically, the second drive unit 302 can be a conveyor belt, etc.
[0056] Reference Figure 1The specific configuration of the output section 40 is described below. In some embodiments, the output section 40 includes a second guide portion 401, which is used to guide the container 20. It is understood that multiple second guide portions 401 can be provided; this embodiment uses two second guide portions 401 as an example for explanation. The two second guide portions 401 can be arranged laterally at a distance perpendicular to the conveying direction of the output section 40. Specifically, during the process of conveying the container 20 by the output section 40, the second guide portion 401 can abut against the bottom side of the carrier plate 201 and be arranged laterally at a distance from the support leg 202. This increases the contact area between the container 20 and the output section 40, avoiding the situation where the support leg 202 directly abuts against the output section 40, causing the container 20 to shake significantly relative to the output section 40, thus effectively improving the stability of the container 20 during conveying. In addition, the output section 40 is also provided with a third drive unit 402, which is used to drive the container 20 to move laterally, so as to transport the container 20 from the output port 130 to the output section 40, thereby ensuring the conveying efficiency and stability of the container 20. Specifically, the second drive unit 302 can be a conveyor belt, etc.
[0057] In some embodiments, the input segment 30 is provided with a second guide rail for sliding the support leg 202. Multiple second guide rails can be provided. Specifically, the second guide rail can extend laterally, and its extension direction can be the same as the input direction of the input segment 30. During the movement of the container 20 along the input segment 30 toward the input port 120, the support leg 202 can slide along the second guide rail. Furthermore, when the support leg 202 is a wheel, and the container 20 is driven by the second drive unit 302, the wheel can roll directly along the second guide rail. This solution, by providing a second guide rail, can further improve the stability of the input segment 30 in conveying the container 20, effectively preventing the container 20 from tipping over.
[0058] In some embodiments, the output section 40 is provided with a third guide rail for sliding the support leg 202. Multiple third guide rails can be provided. Specifically, the third guide rail can extend laterally. It is understood that the extension direction of the third guide rail can be the same as the output direction of the output section 40. During the movement of the container 20 along the output section 40 away from the output port 130, the support leg 202 can slide along the third guide rail. Furthermore, when the support leg 202 is a wheel, and the container 20 is driven by the third drive unit 402, the wheel can roll directly along the third guide rail. This solution, by providing a third guide rail, can further improve the stability of the output section 40 in conveying the container 20, effectively preventing the container 20 from tipping over.
[0059] The following describes the specific conveying process of the conveying system 1 according to a specific embodiment of this application. First, the container 20 is conveyed to the input section 30. After the photoelectric sensor of the input section 30 detects the container 20, the second drive unit 302 drives the container 20 to move towards the input port 120. Next, the container 20 enters the conveying space 110 through the input port 120 and is conveyed in conjunction with the chain plate 200 of the conveying device 10. Then, the container 20 exits the conveying space 110 through the output port 130 and moves to the output section 40. The third drive unit 402 drives the container 20 to move in a direction away from the output port 130, thereby adjusting the height of the container 20. It should be noted that multiple containers 20 can be vertically conveyed on the conveying device 10 at the same time, and the specific number can be determined according to the actual situation. The conveying system 1 of this embodiment can convey containers 20 weighing 300kg-500kg, and the conveying efficiency can reach 240pph (processing 240 containers 20 per hour).
[0060] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.
[0061] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
