[0030] In the process of material handling, especially the parts of the vehicle, due to the requirement of certain production efficiency when the vehicle is produced, manual material handling not only needs to spend more time and cause low efficiency, but also wastes human resources, therefore, in the existing vehicle production process, a mechanical automatic feeding device is generally used to replace manual material handling, and the existing feeding device is continuous feeding, but since the material assembly in the vehicle needs a certain time, therefore, continuous feeding may not match the time of manual assembly of the material to the vehicle, which is easy to cause material stacking or manual assembly of the material to the vehicle, and the feeding effect is poor; and the continuous feeding of the feeding device also continuously consumes energy, which causes resource waste.

[0031] The utility model provides a kind of feeding device 100.

[0032] Please refer to Figures 1-3In the embodiment of the utility model, the feeding device 100 includes a feeding platform 1, a feeding mechanism 2 and a linkage limiting mechanism 3; the feeding platform 1 extends along a first direction, the feeding platform 1 is used for carrying material 200, one end of the feeding platform 1 is provided with a discharge port 134 for the material 200 to pass through, and the feeding platform 1 can move the material 200 along the first direction to the discharge port 134; the feeding mechanism 2 is arranged close to the discharge port 134, the feeding mechanism 2 includes a sliding rail 21 and a trolley 22 slidingly arranged on the sliding rail 21, the sliding rail 21 extends along a second direction, the first direction is perpendicular to the second direction, and the sliding rail 21 is provided with a feeding area 212 and a receiving area 211 along the second direction at intervals, wherein the receiving area 211 is arranged corresponding to the discharge port; the linkage limiting mechanism 3 includes a connecting rod mechanism 33, a first limiting plate 32 and a pressing plate 31 respectively arranged at both ends of the connecting rod mechanism 33, the first limiting plate 32 extends to the discharge port 134, and the pressing plate 31 is arranged at the receiving area 211; the trolley 22 can slide to the receiving area 211 along the sliding rail 21 and push the pressing plate 31, so as to drive the first limiting plate 32 to move and open the discharge port 134 through the connecting rod mechanism 33, so that the material 200 can be discharged to the trolley 22 through the discharge port 134, and the trolley 22 is used for conveying the material 200 along the second direction to the feeding area 212.

[0033] The feeding device 100 of this utility model provides material 200 through a feeding platform 1, and the material 200 can be transported on the feeding platform 1 to the discharge port 134 for discharge. A feeding mechanism 2 is provided near the discharge port 134. The feeding mechanism 2 consists of a slide rail 21 and a trolley 22. The trolley 22 can move on the slide rail 21 to catch the material 200 falling from the discharge port 134, and further move the material 200 to the feeding area 212 to complete the feeding process of the material 200. By setting a linkage limiting mechanism 3, when the trolley 22 moves on the slide rail 21 and reaches the receiving area 211, it will push the pressure plate 31, which will further drive the first limiting plate 32 located at the discharge port 134 to move through the linkage mechanism 33, thereby opening the discharge port 134 so that the material 200 located at the discharge port 134 can be accurately discharged into the trolley 22 located exactly in the receiving area 211. The linkage mechanism 33 ensures that the materials 200 on the feeding platform 1 can fall accurately into the trolley 22, and the trolley 22 completes the final feeding process. Compared with the feeding device 100 in the prior art, the feeding device 100 in this embodiment can only open the discharge port 134 after the trolley 22 reaches the receiving area 211 and pushes the pressure plate 31, so that the materials 200 can be discharged from the discharge port 134. This avoids the materials 200 piling up in the receiving area 211. After the materials 200 on the trolley 22 are taken away, the trolley 22 can move along the slide rail 21 to the receiving area 211 in time to receive the materials. This better matches the time for manually assembling the materials 200 to the vehicle, avoids wasting time waiting for the materials 200 and resulting in low production efficiency, and has a better feeding effect. In addition, the trolley 22 and the feeding platform 1 do not need to run continuously, reducing energy waste and achieving the purpose of energy saving.

[0034] It should be noted that as the trolley 22 moves toward the receiving area 211, it abuts against and pushes the push plate to move in the second direction, thereby driving the first limiting plate 32 to gradually open the discharge port 134 through the linkage structure. When the trolley 22 is precisely located in the receiving area 211, the first limiting plate 32 can just fully open the discharge port 134, so that the material 200 can just fall into the trolley 22.

[0035] Furthermore, the trolley 22 is also equipped with a receiving trough, into which the material 200 falls to prevent the material 200 from falling outside the trolley 22.

[0036] like Figure 1 As shown, the first direction is the front-to-back direction, the second direction is the left-to-right direction, and the vertical direction is the up-to-down direction.

[0037] In an embodiment, the linkage mechanism 33 comprises a first linkage 331, a second linkage 332 and a third linkage 333 connected in sequence, one end of the first linkage 331 away from the second linkage 332 is connected with the pressing plate 31, one end of the third linkage 333 away from the second linkage 332 is connected with the first limiting plate 32 through a rotating shaft 334, the rotating shaft 334 is rotatably connected to the feeding platform 1, and the rotating shaft 334 extends along the first direction; the first linkage 331 has a connecting position between the two ends thereof, and the connecting position is rotatably connected to the feeding platform 1, when the trolley 22 slides along the slide rail 21 to the material receiving area 211 and pushes the pressing plate 31, the opposite two ends of the first linkage 331 can be rotated around the connecting position, and the third linkage 333 and the rotating shaft 334 are pulled to rotate through the second linkage 332, and the first limiting plate 32 rotates with the rotating shaft 334 to open the discharging port 134.

[0038] It can be understood that the linkage mechanism 33 comprises the first linkage 331, the second linkage 332 and the third linkage 333 connected in sequence, forming a stable mechanical transmission structure, wherein the first linkage 331 is connected with the feeding platform 1, the rotating shaft 334 is also rotatably connected to the feeding platform 1, and the position of the rotating shaft 334 along the vertical direction, the first direction and the second direction remains unchanged, and only the rotating shaft 334 can rotate, thereby ensuring the structural stability of the entire linkage mechanism 33, when the first linkage 331 rotates around the connecting position, the movement direction of one end of the first linkage 331 away from the pressing plate 31 is opposite to the movement direction of the pressing plate 31, thereby being able to pull the second linkage 332 to move, the second linkage 332 moves to pull the third linkage 333, and since one end of the third linkage 333 is connected with the rotating shaft 334, the end of the third linkage 333 connected with the second linkage 332 rotates around the rotating shaft 334, thereby causing the rotating shaft 334 to also rotate, and the first limiting plate 32 connected with the rotating shaft 334 rotates to open the discharging port 134; through the hinged connection mode, the included angle between the first linkage 331, the second linkage 332 and the third linkage 333 can be adaptively changed during the movement, the flexibility is better, the mechanism is compact, and the structural arrangement is reasonable.

[0039] Specifically, the second linkage 332 is located at the top of the first linkage 331 and the third linkage 333; the third linkage 333 and the first limiting plate 32 are respectively connected with the outer edge of the rotating shaft 334, and one end of the third linkage 333 and one end of the first limiting plate 32 can be further welded to the rotating shaft 334 through the welding mode in the prior art, thereby further ensuring the structural stability.

[0040] Further, the first limiting plate 32 is a rectangular limiting plate, one short side of which is connected with the rotating shaft 334. When the first limiting plate 32 closes the discharging opening 134, the rotating shaft 334 is located at the top of the first limiting plate 32. During the process of opening the discharging opening 134 by the first limiting plate 32, the rotating shaft 334 drives the first limiting plate 32 to rotate, so that finally the rotating shaft 334 is located at one side of the first limiting plate 32.

[0041] In an embodiment, the first connecting rod 331 includes two supporting rods 3311, one end of each of the two supporting rods 3311 is connected with the pressing plate 31 and the second connecting rod 332 respectively, and the other end of each of the two supporting rods 3311 is connected with the outer ring of a bearing 3312, and the bearing 3312 forms a connecting position. The feeding platform 1 is provided with a connecting rod 135 at a position close to the discharging opening 134, the connecting rod 135 extends in the first direction, and the inner ring of the bearing 3312 is sleeved on the connecting rod 135.

[0042] It can be understood that, by using the bearing 3312 as the connecting position, the two supporting rods 3311 can rotate smoothly around the connecting rod 135, and the low-friction characteristic of the bearing 3312 ensures smooth and accurate rotation, so that the first connecting rod 331 can respond quickly when being pushed by the trolley 22, reduces the motion error, and improves the motion accuracy of the whole connecting rod mechanism 33. In addition, the use of the bearing 3312 significantly reduces the direct friction between the supporting rods 3311 and the connecting rod 135, thereby reducing wear and making the connecting rod mechanism 33 more flexible. Furthermore, by providing the connecting rod 135, the stability of the connecting rod mechanism 33 is further enhanced, and the reliability is better.

[0043] Further, the lengths of the two supporting rods 3311 can be the same or different. When the lengths are the same, the movement distance of the second connecting rod 332 pulled by the first connecting rod 331 is the same as the distance of the pressing plate 31 pushed by the trolley 22, so that it is easier to control the timing of the material 200 falling from the discharging opening 134, to ensure that the material 200 can accurately fall into the trolley 22. When the lengths are different, the movement distance of the first connecting rod 331 pulled can be greater than the distance of the pressing plate 31 pushed by the trolley 22, so as to realize quick response and quickly open the discharging opening 134 by pushing the pressing plate 31.

[0044] Specifically, the two supporting rods 3311 are located on the same straight line, and one end of each of the two supporting rods 3311 is welded to the outer ring of a bearing 3312 by using the welding technology in the prior art, so as to keep the structure stable and more reliable.

[0045] In an embodiment, the pressing plate 31 is connected with the first connecting rod 331 through a supporting rod 336, and the supporting rod 336 is further provided with a reinforcing rib 335, two ends of the reinforcing rib 335 are connected with the supporting rod 336 and the first connecting rod 331 respectively.

[0046] It can be understood that, by connecting the pressing plate 31 through the support rod 336, when the pressing plate 31 is pushed, the force can be quickly transmitted to the first connecting rod 331 through the support rod 336, and at the same time, when the first connecting rod 331 rotates around the rotating shaft 334, the pressing plate 31 is always located on one side of the trolley 22 and abuts against the trolley 22. The arrangement of the reinforcing rib 335 significantly enhances the structural strength of the support rod 336, so that the support rod 336 can be more stable when pushed by the trolley 22 and is not easy to deform or break.

[0047] Specifically, the support rod 336 and the reinforcing rib 335 are connected to the same support rod 3311, and the support rod 336, the reinforcing rib 335 and the support rod 3311 form a triangular stable structure; the reinforcing rib 335 is a reinforcing rod, and the two ends thereof are connected to the support rod 336 and the support rod 3311 by welding, thereby enhancing the structural strength of the connecting mechanism.

[0048] In an embodiment, the feeding platform 1 is provided with a support frame 13, the support frame 13 surrounds a discharging opening 134, and the support frame 13 includes a top plate 131, a bottom plate 133 and two side plates 132. The top plate 131 is located at the top of the discharging opening 134, the top portions of the two side plates 132 are respectively connected to the two sides of the top plate 131 along the second direction, and the bottom portions of the two side plates 132 are connected through the bottom plate 133, and the bottom plate 133 is installed at the bottom of the feeding platform 1. The rotating shaft 334 is rotationally connected to the bottom of the top plate 131, and the connecting rod 135 is arranged on the bottom plate 133.

[0049] It can be understood that, by arranging the support frame 13 and surrounding the discharging opening 134 with the support frame 13, and the support frame 13 being a frame structure composed of the top plate 131, the bottom plate 133 and the two side plates 132, the discharging opening 134 formed is more stable. By arranging the rotating shaft 334 and the connecting rod 135 of the connecting rod structure on the support frame 13, the structural stability of the connecting rod mechanism 33 is significantly improved, so that the first limiting plate 32 can effectively abut against the material 200 to prevent the material 200 from directly falling into the material receiving area 211. Moreover, the combination of the top plate 131, the bottom plate 133 and the two side plates 132 makes the structure of the support frame 13 simpler and facilitates installation and arrangement.

[0050] It should be noted that the closing of the discharging opening 134 by the first limiting plate 32 does not mean that the first limiting plate 32 can close the discharging opening 134, but only ensures that the first limiting plate 32 can abut against the material 200 to avoid the material 200 from directly falling from the discharging opening 134.

[0051] In an embodiment, the support frame 13 encloses a discharging channel extending in the first direction, the discharging channel is the discharging opening 134 close to the opening of the feeding mechanism 2, and the discharging channel is the feeding opening away from the opening of the feeding mechanism 2; the linkage limiting mechanism 3 further comprises a second limiting plate 34 connected to the rotating shaft 334 and extending to the feeding opening; when the first limiting plate 32 rotates with the rotating shaft 334 to open the discharging opening 134, the second limiting plate 34 rotates with the rotating shaft 334 to close the feeding opening.

[0052] It can be understood that the first limiting plate 32 and the second limiting plate 34 are both connected to the rotating shaft 334, so that the first limiting plate 32 and the second limiting plate 34 can act in concert, when the first limiting plate 32 opens the discharging opening 134, the second limiting plate 34 closes the feeding opening, so that the remaining materials 200 cannot enter the discharging channel, only the materials 200 in the limiting channel can fall into the trolley 22, thereby accurately controlling the number of materials 200 discharged, avoiding the disorderly flow and accumulation of materials 200, and facilitating management.

[0053] Specifically, in the present embodiment, the discharging channel is configured to allow only one material 200 to exist, so that only one material 200 falls from the discharging opening 134 to the trolley 22 each time. It should be noted that according to actual work requirements, the discharging channel can be appropriately extended in length, so as to be configured to run multiple materials 200, and directly make a specified number of materials 200 fall from the discharging opening 134 to the trolley 22 when discharging.

[0054] Further, the first limiting plate 32 and the second limiting plate 34 are arranged at intervals on the rotating shaft 334, and the first limiting plate 32 and the second limiting plate 34 are respectively located on opposite sides of the top plate 131 in the first direction, so that at least one material 200 can be accommodated between the first limiting plate 32 and the second limiting plate 34.

[0055] As shown in Figure 2 and Figure 3 In an embodiment, the top of the top plate 131 is further connected with a return spring 14, the rotating shaft 334 is provided with a connecting lug, and the end of the return spring 14 away from the top plate 131 is connected with the connecting lug; when the first limiting plate 32 rotates with the rotating shaft 334 to open the discharging opening 134, the connecting lug rotates with the rotating shaft 334 and stretches the return spring 14, when the trolley 22 is separated from the pressing plate 31, the return spring 14 can pull the connecting lug and drive the rotating shaft 334 to rotate under the action of elastic restoring force, so that the first limiting plate 32 rotates with the rotating shaft 334 to close the discharging opening 134, and the second limiting plate 34 rotates with the rotating shaft 334 to open the feeding opening.

[0056] Understandably, the design of the return spring 14 enables the first limiting plate 32 and the second limiting plate 34 to automatically reset. When the trolley 22 disengages from the pressure plate 31, the return spring 14 pulls the connecting ear under the action of elastic restoring force, driving the rotating shaft 334 to rotate, thereby causing the first limiting plate 32 to close the discharge port 134 and the second limiting plate 34 to open the feed port. This automatic reset function simplifies the operation and ensures the continuous action of the linkage mechanism 33, so that after the trolley 22 leaves the receiving area 211, the discharge port 134 can be closed in time and the feed port can be opened in time, so that there is material 200 in the discharge channel, and it is also ready for the next material 200 to be discharged into the trolley 22, ensuring the timeliness of the discharge and making it more reliable.

[0057] It should be noted that the return spring 14 can be a tension spring as used in the prior art.

[0058] like Figure 2 As shown, Figure 2 This is also the state diagram when the first limiting plate 32 opens the discharge port 134. At this time, the reset spring 14 is stretched, and the connecting ear is blocked behind the third connecting rod 333. When the trolley 22 disengages from the pressure plate 31, the reset spring 14 pulls the connecting ear to reset the first limiting plate 32 and the second limiting plate 34. That is, the second limiting plate 34 opens the feed port, and the first limiting plate 32 closes the discharge port 134.

[0059] In another embodiment, the end of the return spring 14 away from the top plate 131 can also be connected to the end of the third link 333 connected to the second link 332, so that the elastic restoring force of the return spring 14 can directly pull the third link 333 to rotate, thereby causing the rotating shaft 334 to rotate and reset the first limiting plate 32 and the second limiting plate 34.

[0060] In one embodiment, the support frame 13 is also provided with a sensor for sensing the material 200 located on the feeding platform 1.

[0061] Understandably, the sensor can monitor the material 200 on the feeding platform 1 in real time, including the quantity of material 200, so as to obtain material 200 information in a timely manner and ensure the continuity and accuracy of material 200 supply.

[0062] Furthermore, when the sensor detects that the quantity of material 200 is below a certain level, it will alert the user to add material 200 via other alarm devices.

[0063] In one embodiment, the feeding platform 1 has a bearing surface 11 for bearing material 200. The two ends of the bearing surface 11 along the first direction are a feeding end 112 and a discharging end 111, respectively. The discharging port 134 is located at the discharging end 111. The bearing surface 11 is inclined, and the height of the feeding end 112 is higher than the height of the discharging end 111.

[0064] It can be understood that the carrier surface 11 arranged obliquely makes the material 200 slide naturally downward the discharge port 134 under the action of gravity, reducing the dependence on mechanical driving, and such design not only simplifies the structure of the feeding platform 1, but also reduces energy consumption.

[0065] In an embodiment, the feeding platform 1 comprises a plurality of rollers 12 arranged in sequence and at intervals along the first direction, and the roller shafts of the rollers 12 extend along the second direction, and the tops of the plurality of rollers 12 are located in the same plane to form the carrier surface 11.

[0066] It can be understood that using the rollers 12 as part of the carrier surface 11 can significantly reduce the frictional resistance between the material 200 and the carrier surface 11, and the friction is greatly reduced when the material 200 slides on the rollers 12, so that the material 200 can move more smoothly, improving the conveying efficiency; the use of the rollers 12 reduces the kinetic energy loss when the material 200 slides, reducing the demand for power.

[0067] The above only describes exemplary embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
