Description

Technical Field

[0001] This invention relates to the field of material conveying technology, and more particularly to a material conveying device. Background Technology

[0002] In current product manufacturing operations, material supply typically relies on manual operation, with material management personnel responsible for the actual distribution and delivery of materials according to the production schedule. However, this traditional approach has the following problems: On the one hand, due to the time difference between human judgment and execution, material supply is prone to being delivered too early or too late. The former may cause materials to occupy the work area, affecting on-site work efficiency and space utilization, while the latter will directly slow down the production cycle, thereby reducing the overall output efficiency.

[0003] On the other hand, to ensure an adequate supply of materials at workstations, some factories choose to store materials nearby within the workers' operating range. While this method can reduce waiting time for materials to some extent, it occupies a large area, making the already potentially cramped operating environment even more crowded and cluttered. Secondly, the frequent retrieval and organization of materials increases the workload of workstation workers and reduces production efficiency.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] In view of the problems pointed out in the background art, this application provides a material conveying device with a simple structure, in which material boxes can be vertically stacked for storage and conveyed individually.

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution: In some embodiments of this application, a material conveying device is provided, including a frame, a material box disposed on the frame, a material box stop component, a drive assembly, a foot pedal mechanism, and a conveying platform. Material boxes are used to load materials; multiple material boxes are stacked vertically on the frame. The material box stop component is installed on the frame and makes limiting contact with the bottom material box to prevent multiple material boxes from falling. The material platform moves up and down along the vertical direction of the frame and is located below the material box; A drive component is used to drive the material box stop component to move, so that the material box stop component disengages from the bottommost material box. A foot pedal mechanism is used to control the movement of the material platform and drive components by external force. When the foot pedal is pressed, the drive assembly drives the material box stop component to move and disengage from the material box, while the material platform moves upward to support multiple material boxes. When the foot pedal is released, the material platform moves downward, and the bottommost material box falls with the material platform. At the same time, the drive component drives the material box stop component to reset and make contact with the limit of the material box on the upper layer. A conveyor platform, located on one side of the material platform, is used to convey material boxes that fall with the material platform.

[0007] The material conveying device has a simple structure. By simply stepping on the foot pedal mechanism, a single material box can be separated from the three-dimensional storage area and conveyed to the front of the frame, which simplifies the operation process and improves work efficiency.

[0008] In some embodiments of this application, the foot pedal mechanism includes: A lever, the middle of which is rotatably connected to the frame, one end of which is the force-applying end and the other end is the connecting end; The connecting rod has its bottom end rotatably connected to the connecting end of the lever; A support frame is rotatably connected to the top of a connecting rod. The support frame is slidably mounted on the machine frame, and the material platform is mounted on the support frame.

[0009] The foot pedal mechanism has a simple structure, allowing operators to control it by simply stepping on it with their feet, freeing up their hands and making it easy to operate.

[0010] In some embodiments of this application, two material box stop components are provided, one on each side of the material box, and rotatably mounted on the frame. The driving component includes: The upper ejector component is fixedly connected to the support frame; Two horizontal rods, one end of which is connected to the material box stop components on both sides respectively, and the other end of the horizontal rods is located above the upper ejector component; When the foot pedal is pressed, the upper ejector component moves upward with the support frame, and drives the material box stop component to flip through the horizontal rod, so that the material box stop component disengages from the bottom material box.

[0011] The foot pedal mechanism simultaneously drives the drive assembly to move, and drives the material box stop component to move.

[0012] In some embodiments of this application, the drive assembly further includes a spring connected to the transverse rod for resetting the transverse rod.

[0013] In some embodiments of this application, a sliding assembly is provided on the frame, the sliding assembly slides up and down along the frame, and the support frame is fixedly connected to the sliding assembly. The sliding assembly is preferably a linear rolling bushing assembly.

[0014] In some embodiments of this application, the top edge of the material box has an extended flange, and the material box stop component is a plate-shaped structure that makes limiting contact with the bottom surface of the extended flange.

[0015] In some embodiments of this application, the conveying platform is inclined downwards; the side of the material platform near the conveying platform is rotatably connected to the support frame, and the side away from the conveying platform is supported on the support frame; a lower ejector component is provided below the material platform; when the material platform moves downwards and approaches the conveying platform, the side of the material platform away from the conveying platform is supported on the lower ejector component, causing the material platform to tilt downwards, so that the material box flows onto the conveying platform under the action of gravity.

[0016] In some embodiments of this application, the support frame is provided with a support component, and the bottom of the material platform on the side away from the conveying platform is supported on the support component, so that the material platform is set horizontally; the bottom of the material platform is provided with a support rod, which is used to abut against the lower ejection component to make the material platform tilt downward.

[0017] The material platform is tilted to allow the material box to slide down under its own weight.

[0018] In some embodiments of this application, the conveying platform and the material platform are respectively provided with roller tracks.

[0019] In some embodiments of this application, the frame is composed of several connected tubing. The frame is preferably constructed using lean tubing, which results in a simple structure and low cost.

[0020] This application also provides a material conveying device, including: Compared with the prior art, the advantages and positive effects of the present invention are: The material conveying device in the above embodiments realizes three-dimensional stacked storage of material boxes within a limited and compact working area, making full use of three-dimensional vertical space resources and significantly increasing the material capacity per unit area. Its structure is simple, and operators can easily separate individual material boxes from the three-dimensional storage area and convey them to the front of the frame by simply stepping on the foot pedal mechanism. This simplifies the operation process for workers to retrieve materials, not only reducing the workload of workers who frequently move materials, but also effectively avoiding production delays caused by untimely material supply or misoperation, and significantly improving work efficiency.

[0030] like Figures 1-10 As shown, some embodiments of this application provide a material conveying device. This material conveying device can be applied to various product manufacturing industries, is suitable for relatively narrow spaces, can store a certain amount of material, and transport the material in single containers to the workers.

[0031] like Figure 1 As shown, the material conveying device includes a frame 100, a material box 200, a material box stop component 300, a material platform 400, a conveying platform 500, a drive assembly 600, and a foot pedal mechanism 700.

[0032] The frame 100 is composed of several tubular connections.

[0033] Different types of lean pipes can be used for the pipes. The frame 100, which is composed of lean pipes, is lightweight, wear-resistant, and flexible in assembly.

[0034] The frame 100 is divided into two parts: the front frame 110 and the rear frame 120. For ease of description, the side closer to the operator is called the front direction, and the side farther away from the operator is called the rear direction.

[0035] The top of the front rack 110 is a three-dimensional storage area, where multiple material boxes 200 are stacked vertically. The top of each material box 200 is open, and materials can be loaded inside.

[0036] The material box stop component 300 is installed on the front frame 110 and makes limiting contact with the bottom material box 200 to prevent multiple material boxes 200 from falling. That is, multiple material boxes 200 are supported on the top of the front frame 110 by the material box stop component 300.

[0037] The material box stop component 300 is movable, and it has a blocking position and a releasing position.

[0038] In the blocking position, the material box stop component 300 makes limiting contact with the bottom material box 200 to prevent the material box 200 from falling; in the releasing position, the material box stop component 300 disengages from the bottom material box 200, releasing the obstruction to the falling of the bottom material box 200.

[0039] The drive assembly 600 is used to drive the material box stop component 300 to move. When the drive assembly 600 drives the material box stop component 300 from the blocking position to the release position, the material box stop component 300 can release the obstruction of the falling of the bottom material box 200.

[0040] The material platform 400 is located below the material box 200 and is used to receive the material box 200 falling from above. The material platform 400 can move up and down vertically along the front frame 110.

[0041] The foot pedal mechanism 700 is connected to the material platform 400 and the drive component 600. The foot pedal mechanism 700 is controlled by external force, which can make the material platform 400 and the drive component 600 move.

[0042] In the initial state, such as Figure 2 and Figure 5 As shown, the material box stop component 300 is in the blocking position, and multiple material boxes 200 are stacked on the front frame 110.

[0043] When the foot pedal 700 is pressed, as Figure 3 and Figure 6 As shown, the foot pedal mechanism 700 drives the material platform 400 to move upward. When the foot pedal is in place, the drive component 600 drives the material box stop component 300 to move to the release position, so that it is disengaged from the bottom material box 200. At the same time, the material platform 400 supports multiple material boxes 200 upward. When the foot pedal is released at 700, as Figure 4 As shown, under the action of gravity, the material platform 400 moves downward, and the bottom material box 200 falls with the material platform 400. At the same time, the drive component 600 drives the material box stop component 300 to reset to the blocking position and make contact with the upper material box 200. That is, the other material boxes 200 remain in their original positions on the front frame 110.

[0044] On the rear frame 120, there is a conveying platform 500, which is located on one side of the material platform 400 and is used to convey the material box 200 that falls with the material platform 400.

[0045] The aforementioned material conveying device enables the three-dimensional stacking and storage of material boxes 200 within a limited and compact working area, making full use of three-dimensional vertical space resources and significantly increasing the material capacity per unit area. Operators can easily separate individual material boxes 200 from the three-dimensional storage area and convey them to the front of the frame 100 by simply stepping on the foot pedal mechanism 700, simplifying the material handling process for workers. This not only reduces the workload of workers frequently moving materials but also effectively avoids production delays caused by untimely material supply or misoperation, significantly improving work efficiency.

[0046] In some embodiments of this application, the foot pedal mechanism 700 includes a lever 710, a connecting rod 720, and a support frame 730.

[0047] The middle part of lever 710 is rotatably connected to frame 100. One end of lever 710 is the force-applying end, and the other end is the connecting end.

[0048] The bottom end of the connecting rod 720 is rotatably connected to the connecting end of the lever 710.

[0049] The top end of the connecting rod 720 is rotatably connected to the support frame 730.

[0050] The support frame 730 is slidably mounted on the frame 100, and the material platform 400 is mounted on the support frame 730.

[0051] The support frame 730 is a support structure composed of multiple rods.

[0052] When the foot pedal is pressed, the lever 710 drives the support frame 730 to move upward through the connecting rod; when the foot pedal is released, the support frame 730 slides downward under the action of gravity, and the lever 710 returns to its original position.

[0053] In some embodiments of this application, the lever 710 can be connected to the frame 100 via the first linear rotation sliding sleeve assembly 910.

[0054] See Figure 7The first linear rotation sliding sleeve assembly 910 includes a first sliding rod 911 and a first sliding sleeve 912.

[0055] The first slide bar 911 is fixedly connected at both ends to the two uprights on the rear side of the frame 100.

[0056] The first sliding sleeve 912 is rotatably mounted on the sliding rod.

[0057] The first linear rotation sliding sleeve assembly 910 also includes a first sliding sleeve positioning ring 913. The two ends of the first sliding sleeve 912 are positioned by the first sliding sleeve positioning ring 913, which restricts its linear movement along the first sliding rod 911.

[0058] The middle part of lever 710 is fixedly connected to the first sliding sleeve 912.

[0059] The connecting end of lever 710 is rotatably connected to the bottom end of connecting rod 720 via a hinge.

[0060] The top end of the connecting rod 720 is rotatably connected to the support frame 730 via a rotatable joint.

[0061] In some embodiments of this application, two foot pedal mechanisms 700 are provided.

[0062] The two levers 710 are connected by a horizontally arranged foot pedal 740. By stepping on the foot pedal 740, the two foot pedal mechanisms 700 can be driven to move simultaneously.

[0063] By setting two foot pedal mechanisms 700, the structural strength of the foot pedal mechanism 700 can be improved, ensuring that the support frame 730 moves smoothly up and down, thereby ensuring that the material platform 400 and material box 200 on the support frame 730 move smoothly.

[0064] In some embodiments of this application, the material box 200 is generally a cuboid structure with an open top, and the bottom of the material box 200 is slightly narrower than the top opening, so as to facilitate the stacking of the material boxes 200.

[0065] The top edge of the material box 200 has an extended flange 210 for easy hand placement, and can also be used as a limiting part to cooperate with the material box stop component 300.

[0066] The material box stop component 300 has a plate-like structure and is rotatably mounted on the crossbars on both sides of the top of the frame 100.

[0067] There are two stop components 300 for the material box, one on the left and one on the right side of the material box 200.

[0068] like Figure 5As shown, when the material box stop component 300 is horizontal, the material box stop component 300 is in the stop position and makes limited contact with the bottom surface of the extended protrusions 210 on the left and right sides of the material box 200, so that the material box 200 is supported on the frame 100.

[0069] like Figure 6 As shown, when the material box stop component 300 is flipped upward at a certain angle, the material box stop component 300 is in the released position. The material box stop component 300 is located on the outside of the extension flange 210 of the material box 200 in the vertical direction, and the bottom material box 200 can fall downward at this time.

[0070] The material box stop component 300 is connected to the frame 100 via the second linear rotation sliding sleeve assembly 920.

[0071] See Figure 8 The second linear rotation sliding sleeve assembly 920 includes a second sliding rod 921 and a second sliding sleeve 922 sleeved on the second sliding rod 921.

[0072] The second sliding sleeve 922 is fixedly connected to the frame 100, and the second sliding rod 921 can rotate circumferentially within the second sliding sleeve 922.

[0073] The second linear rotation sliding sleeve assembly 920 also includes a second sliding sleeve 922 positioning ring. The second sliding rod 921 and the second sliding sleeve 922 are positioned by the second sliding sleeve 922 positioning ring, which restricts the linear displacement between them.

[0074] The material box stop component 300 is fixedly connected to the second slide rod 921. When the second slide rod 921 rotates, it can cause the material box stop component 300 to flip.

[0075] In some embodiments of this application, such as Figure 1 , 5 and Figure 6 As shown, the drive assembly 600 includes an upper ejector component 610.

[0076] The upper ejector component 610 is fixedly connected to the support frame 730. When the support frame 730 moves upward, the upper ejector component 610 can move upward synchronously, lifting the material box stop component 300 upward and flipping it to the release position, so that the material box stop component 300 releases its obstruction of the falling of the bottom material box 200.

[0077] Specifically, the upper ejector component 610 is a vertical pole, which is fixedly connected to the rear side of the support frame 730.

[0078] In some embodiments of this application, the drive assembly 600 includes two transverse rods 620.

[0079] The two transverse bars 620 are arranged in a straight line and are horizontally positioned on the front side of the frame 100.

[0080] The two horizontal rods 620 have their far ends fixedly connected to the material box stop components 300 on both sides (and fixedly connected to the second slide rod 921), while the other ends of the horizontal rods 620 are set close to each other and located above the upper ejector component 610.

[0081] See Figure 6 When the upper ejector component 610 moves upward, it can lift the two ends of the horizontal rod 620 that are close to each other upward. The horizontal rod 620 flips and drives the material box stop component 300 to rotate to the release position.

[0082] In some embodiments of this application, the drive assembly 600 includes two springs 630.

[0083] Two springs 630 are fixed at one end to the frame 100 and at the other end to the transverse rod 620. When the upper ejector 610 moves downward, the transverse rod 620 can be reset by the action of the springs 630, causing the material box stop component 300 to reset to the blocking position. Although the transverse rod 620 can move downward under its own weight after the upper ejector 610 moves downward, in order to prevent the transverse rod 620 from not resetting in time or getting stuck, causing the material box stop component 300 to fail to stop the material box 200 above from falling in time, the springs 630 are set to ensure that the transverse rod 620 and the material box stop component 300 reset in time.

[0084] In some other embodiments of this application, the upper ejector 610 may be disposed below the material box stop component 300, directly driving the material box stop component 300 to move.

[0085] To ensure that the support frame 730 can be raised and lowered smoothly, a sliding component 750 is provided on the frame 100. The sliding component 750 slides up and down along the frame 100, and the support frame 730 is fixedly connected to the sliding component 750.

[0086] Specifically, see Figure 10 Two sliding components 750 are mounted on the rear upright of the front frame 110, and the two sliding components 750 are fixed together by two upper and lower transverse connecting rods. The upper transverse connecting rod is fixedly connected to the rear of the support frame 730.

[0087] The sliding component 750 includes multiple rollers 751, which are used to slide to improve the smoothness of the sliding.

[0088] In some embodiments of this application, the conveyor platform 500 is tilted downwards from back to front, which allows the material box 200 to slide smoothly along the conveyor platform 500 to the front under its own weight.

[0089] The conveyor platform 500 is equipped with roller slides, that is, the conveyor platform 500 has a smooth strip structure, which facilitates the conveying of material boxes 200.

[0090] In some other embodiments of this application, the conveying platform 500 may also be equipped with a conveyor belt, etc.

[0091] In some embodiments of this application, the side of the material platform 400 closest to the conveying platform 500 is rotatably connected to the support frame 730, and the side furthest from the conveying platform 500 is supported on the support frame 730. That is, the front side of the material platform 400 is rotatably connected to the support frame 730, and the rear side of the material platform 400 is supported on the support frame 730.

[0092] Specifically, such as Figure 9 and Figure 11 As shown, the bottom front side of the material platform 400 is rotatably connected to the support frame 730 via the third linear rotating sliding sleeve assembly 930.

[0093] A support member 731 is provided on the rear side of the support frame 730 for supporting the rear bottom of the material platform 400. When the material platform 400 is supported on the support member 731, the material platform 400 remains in a horizontal state.

[0094] A lower ejector component 800 is provided below the material platform 400, and the lower ejector component 800 is fixedly connected to the bracket.

[0095] The bottom of the material platform 400 is provided with a support rod 410, which is used to abut against the lower ejector component 800 to tilt the material platform 400 downward.

[0096] In the initial state, the rear of the material platform 400 is supported on the lower ejector component 800, and the material platform 400 remains tilted downward.

[0097] When the foot pedal is pressed, as the material platform 400 moves upward, it disengages from the lower ejector component 800 and falls to contact with the support component 731, reaching a horizontal position.

[0098] During the process of receiving the falling material box 200, the material platform 400 remains horizontal for the first part, and after the second part comes into contact with the support component 731, it begins to tilt so that the material box 200 can finally slide onto the conveyor platform 500.

[0099] The material platform 400 keeps the material box 200 horizontal when receiving the falling material box 200 to prevent the material box 200 from slipping off prematurely. When the logistics platform falls into place, it keeps the material box 200 in an inclined state so that it can slide out along the inclined surface.

[0100] To facilitate the sliding of the material box 200 along the material platform 400, a roller track is provided on the material platform 400.

[0101] The tilt angle of the material platform 400 is approximately the same as that of the conveyor platform 500, so that the material boxes on it can slide smoothly downwards and be conveyed.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
