Description

Technical Field

[0001] The present invention relates to the technical field of material conveying, and in particular to a material conveying device. Background Art

[0002] In the current production operation model, material supply is usually completed manually, and the material management personnel are 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 differences in human judgment and execution, material supply is prone to being delivered too early or provided 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 rhythm, thereby reducing overall output efficiency.

[0003] On the other hand, to ensure an adequate supply of materials at workstations, some factories choose to store materials within the workers' operating range. While this approach can reduce waiting time for materials to a certain extent, it occupies a larger area, making the already cramped working environment even more crowded and cluttered. Furthermore, the frequent need to retrieve and organize materials increases the workload of workers at the workstations, reducing production efficiency.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application.

In addition, the present invention provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

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

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

[0032] The frame 100 is composed of a plurality of pipes connected together.

[0033] The pipes can be made of different types of lean pipes. The rack 100 composed of lean pipes has the characteristics of being light, wear-resistant and flexible in assembly.

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

[0035] The top of the front frame 110 is a three-dimensional storage area, in which a plurality of material boxes 200 are vertically stacked. The top of the material box 200 is open, and materials can be loaded therein.

[0036] The material box stopper 300 is provided on the front frame 110 and contacts the bottommost material box 200 to prevent the plurality of material boxes 200 from falling. That is, the plurality of material boxes 200 are supported on the top of the front frame 110 by the material box stopper 300.

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

[0038] In the blocking position, the material box stopping component 300 is in limiting contact with the lowermost material box 200 to prevent the material box 200 from falling; in the releasing position, the material box stopping component 300 is disengaged from the lowermost material box 200 to release the blocking of the lowermost material box 200.

[0039] The driving assembly 600 is used to drive the material box stopping component 300 to move. When the driving assembly 600 drives the material box stopping component 300 to move from the blocking position to the releasing position, the material box stopping component 300 can release the falling blockage of the lowermost material box 200.

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

[0041] The pedal mechanism 700 is connected to the material platform 400 and the driving assembly 600. The pedal mechanism 700 is controlled by an external force to enable the material platform 400 and the driving assembly 600 to move.

[0042] In the initial state, such as Figure 2 and Figure 5 As shown, the material box stopping component 300 is located at the blocking position, and a plurality of material boxes 200 are stacked on the front frame 110 .

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

[0044] A conveying platform 500 is provided on the rear frame 120 . The conveying platform 500 is located on one side of the material platform 400 and is used to convey the material box 200 that falls along with the material platform 400 .

[0045] The above-mentioned material conveying device realizes the three-dimensional stacking storage of material boxes 200 in a limited and compact working area, makes full use of the three-dimensional vertical space resources, and greatly increases the material holding capacity per unit area; the operator can separate a single material box 200 from the three-dimensional storage area and convey it to the front side of the rack 100 by simply stepping on the foot pedal mechanism 700, which simplifies the operation process of the staff to take the materials, not only reduces the workload of the workers at the workstations who frequently carry materials, but also effectively avoids production delays caused by untimely material supply or misoperation, and significantly improves work efficiency.

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

[0047] The middle portion of the lever 710 is rotatably connected to the frame 100 , one end of the lever 710 is a force-applying end, and the other end is a 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 supporting frame 730 .

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

[0051] The support frame 730 is composed of a plurality of rods to form a support structure.

[0052] When the force-applying end of the lever 710 is stepped on, the lever 710 drives the support frame 730 to move upward through the connecting rod; when the 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 the present application, the lever 710 may be connected to the frame 100 via a first linear rotation sleeve assembly 910 .

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

[0055] Both ends of the first sliding rod 911 are fixedly connected to the two side vertical rods on the rear side of the rack 100 .

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

[0057] The first linear rotation sliding sleeve assembly 910 further includes a first sliding sleeve positioning ring 913 . Both ends of the first sliding sleeve 912 are positioned by the first sliding sleeve positioning ring 913 to restrict the linear movement of the first sliding sleeve 912 along the first sliding rod 911 .

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

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

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

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

[0062] The force-applying ends of the two levers 710 are connected via a transversely arranged pedal rod 740 . By stepping on the pedal rod 740 , the two pedal mechanisms 700 can be driven to move simultaneously.

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

[0064] In some embodiments of the present application, the material box 200 is a substantially rectangular parallelepiped structure with an open top, and the bottom of the material box 200 is slightly narrower than the top opening to facilitate stacking of the material boxes 200 .

[0065] The top edge of the material box 200 has an extended protrusion 210 to facilitate hand-held placement, and can also serve as a limit portion to cooperate with the material box stop component 300.

[0066] The material box stopping component 300 is a plate-shaped structure, and the material box stopping component 300 is rotatably disposed on the cross bars on both sides of the top of the frame 100 .

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

[0068] like Figure 5As shown, when the material box stopping component 300 is horizontal, the material box stopping component 300 is in the stopping position, and contacts the bottom surfaces of the extended protrusions 210 on the left and right sides of the material box 200 to support the material box 200 on the frame 100.

[0069] like Figure 6 As shown, when the material box stopping component 300 is flipped upward at a certain angle, the material box stopping component 300 is in the released position, and the material box stopping component 300 is located outside the extended protrusion 210 of the material box 200 in the vertical direction. At this time, the lowermost material box 200 can fall downward.

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

[0071] See also 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 further 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 to limit the linear displacement between the two.

[0074] The material box stopping component 300 is fixedly connected to the second slide bar 921. When the second slide bar 921 rotates, the material box stopping component 300 can be driven to flip.

[0075] In some embodiments of the present application, Figure 1 、 5 and Figure 6 As shown, the drive assembly 600 includes an upper ejection component 610 .

[0076] The upper ejection member 610 is fixedly connected to the support frame 730. When the support frame 730 moves upward, the upper ejection member 610 can move upward synchronously, pushing the material box stop member 300 upward to flip it to the release position, so that the material box stop member 300 releases the falling block of the lowermost material box 200.

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

[0078] In some embodiments of the present 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 disposed on the front side of the frame 100 .

[0080] One end of the two transverse rods 620 that is away from each other is fixedly connected to the material box stop components 300 on both sides (fixedly connected to the second slide bar 921 ), and the other ends of the transverse rods 620 are arranged close to each other and located above the upper ejection component 610 .

[0081] See also Figure 6 When the upper ejection component 610 moves upward, the ends of the transverse rods 620 that are close to each other can be pushed upward, and the transverse rods 620 flip and drive the material box stopping component 300 to rotate to the release position.

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

[0083] Two springs 630 are each secured to the frame 100 at one end and connected to the transverse rod 620 at the other end. When the upper ejection member 610 moves downward, the transverse rod 620 is reset under the action of the springs 630, driving the material box stop member 300 back to its blocking position. Although the transverse rod 620 can move downward under its own weight after the upper ejection member 610 moves downward, to prevent the transverse rod 620 from resetting in time or becoming stuck, thereby preventing the material box stop member 300 from being able to stop the material box 200 from falling, the springs 630 are provided to ensure that the transverse rod 620 and the material box stop member 300 are reset in a timely manner.

[0084] In some other embodiments of the present application, the upper ejection component 610 may be disposed below the material box stopping component 300 to directly drive the material box stopping component 300 to move.

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

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

[0087] The sliding assembly 750 includes a plurality of rollers 751 , and the sliding of the rollers 751 is used to improve the sliding smoothness.

[0088] In some embodiments of the present application, the conveying platform 500 is arranged to be tilted downward from the back to the front, so that the material box 200 can slide smoothly to the front side along the conveying platform 500 under its own gravity.

[0089] The conveying platform 500 is provided with a roller slideway, that is, the conveying platform 500 is a smooth strip structure, which is convenient for conveying the material box 200.

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

[0091] In some embodiments of the present application, the side of the material platform 400 close to the conveying platform 500 is rotatably connected to the support frame 730, and the side away 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, if Figure 9 and Figure 11 As shown, the front bottom of the material platform 400 is rotatably connected to the support frame 730 through a third linear rotation sleeve assembly 930 .

[0093] A support component 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 component 731, the material platform 400 remains in a horizontal state.

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

[0095] A support rod 410 is provided at the bottom of the material platform 400 , and the support rod 410 is used to abut against the lower ejection component 800 to tilt the material platform 400 downward.

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

[0097] When the pedal is stepped on and the material platform 400 moves upward, the material platform 400 separates from the lower ejection component 800 and falls to abut against the support component 731, and is in a horizontal state.

[0098] The material platform 400 also remains horizontal in the first part of the process of receiving the falling material box 200 , and begins to tilt after contacting the support component 731 in the second part so that the material box 200 can finally slide onto the conveying platform 500 .

[0099] The material platform 400 remains horizontal when receiving the falling material box 200 to prevent the material box 200 from sliding down prematurely. When the logistics platform falls into place, it remains tilted to facilitate the material box 200 to slide out along the tilted surface.

[0100] In order to facilitate the material box 200 to slide out along the material platform 400 , a roller slide is provided on the material platform 400 .

[0101] The inclination angle of the material platform 400 is substantially the same as that of the conveying platform 500 , so that the material boxes thereon can slide downwards smoothly for conveyance.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
