[0047] In modern industrial production and manufacturing, the feeding device is an indispensable part of the production line. Its main function is to automatically transport products from the storage area to the location where they need to be fed.

[0048] Existing feeding devices typically use a single transmission path to transfer products. While this method is simple, it has certain limitations. A single transmission path may cause product congestion during the transmission process, affecting the normal operation of the feeding device.

[0049] This utility model proposes a feeding device to improve the scheduling capability of the feeding device.

[0050] Please see 1 and Figure 2 In one embodiment, the feeding device includes a base 100, a feeding assembly, and a feeding return assembly. The feeding assembly is located on the base 100 and has a feeding channel. The width of the feeding channel is adapted to the product 510 so that the product 510 is sequentially conveyed from the feed end 211 of the feeding channel to the discharge end 221 of the feeding channel. The feeding and return assembly is located on the base 100. The feeding and return assembly includes a first conveyor belt 310 and a second conveyor belt 320 arranged side by side. The return end 312 of the first conveyor belt 310 and the feeding end 321 of the second conveyor belt 320 are connected. The receiving end 311 of the first conveyor belt 310 and the feeding end 211 of the conveying channel are respectively connected to the unloading end 322 of the second conveyor belt 320, so that part of the products 510 at the unloading end 322 of the second conveyor belt 320 are conveyed to the feeding end 211 of the conveying channel, and part of the products 510 are conveyed to the receiving end 311 of the first conveyor belt 310 and then conveyed by the return end 312 of the first conveyor belt 310 to the feeding end 321 of the second conveyor belt 320.

[0051] The base 100 provides support and a mounting foundation for the entire feeding device. The material transfer component is used to sequentially transfer the products 510 to the feeding position. The product 510 can be a bottle or cap, etc. The width of the material transfer channel can be flexibly set according to the size of the product 510; therefore, no limitations are placed on the width of the material transfer channel or the product 510. In one embodiment, the feeding device is applied to a spray painting production line. The feeding device is used to transfer the product 510 from the product box 500 to the tooling fixture 700 used for spray painting. At least one tooling fixture 700 corresponds to the feeding position. The tooling fixture 700 moves in a straight line. The material transfer direction of the material transfer component is the same as the movement direction of the tooling fixture 700, and the material transfer speed of the material transfer component is adapted to the movement speed of the tooling fixture 700 to ensure that each product 510 is placed into the tooling fixture 700 in a one-to-one correspondence. In one embodiment, the discharge end 221 of the material transfer channel is located above and close to the loading position, allowing the product 510 to fall directly from the discharge end 221 onto the tooling fixture 700, completing the loading process. In another embodiment, a pressure roller 600 is also provided above the tooling fixture 700. The pressure roller 600 is used to further press the product 510 onto the tooling fixture 700, preventing the product 510 from falling off. Of course, in other embodiments, the loading device can also be applied to other production lines such as welding, and the loading position can also be equipped with other structures such as an operating position; no limitations are imposed here. Thus, by adapting the width of the material transfer channel to the product 510, it can be ensured that the product 510 arrives at the loading position sequentially to correspond one-to-one with the tooling fixture 700 or other structures at the loading position, improving loading accuracy.

[0052] In one embodiment, the loading end 321 of the second conveyor belt 320 is located close to the product box 500. Products 510 are moved from the product box 500 to the loading end 321 of the second conveyor belt 320 manually or by a robotic arm. In one embodiment, the gap between the first conveyor belt 310 and the second conveyor belt 320 is small or even nonexistent to prevent products 510 from getting stuck in the gap and to ensure smooth reciprocating movement between the second conveyor belt 320 and the first conveyor belt 310. The specific size of the gap can be flexibly set according to actual needs and is not limited here. In one embodiment, the second conveyor belt 320 can accommodate multiple products 510 in both its width and length directions, meaning it can simultaneously transport multiple rows and columns of products 510. These multiple rows and columns of products 510 enter the material conveying channel sequentially from the unloading end 322 of the second conveyor belt 320 through the feeding end 211 of the material conveying channel. In one embodiment, the first conveyor belt 310 and the second conveyor belt 320 are of the same length to ensure that the receiving end 311 of the first conveyor belt 310 is connected to the unloading end 322 of the second conveyor belt 320, and the return end 312 of the first conveyor belt 310 is connected to the loading end 321 of the second conveyor belt 320. The length and width of the second conveyor belt 320 and the first conveyor belt 310 can be flexibly set according to actual conditions and are not limited here. In one embodiment, the loading and return assembly also includes two second power components 330, which are respectively driven and connected to the first conveyor belt 310 and the second conveyor belt 320. The second power components 330 can be motors, cylinders, or hydraulic cylinders, etc., and are not limited here. Of course, in other embodiments, only one second power component 330 may be provided, and the second power component 330 may be driven and connected to both the first conveyor belt 310 and the second conveyor belt 320 simultaneously through a gear rack or worm gear structure, and is not limited here.

[0053] Product 510 is conveyed from the loading end 321 of the second conveyor belt 320 to the unloading end 322 of the second conveyor belt 320, and then enters the conveying channel through the inlet end 211, and is then conveyed to the outlet end 221 of the conveying channel, reaching the loading position. During this process, since the conveying channel only allows products 510 to enter sequentially, after the loading device has been running for a period of time, multiple products 510 will accumulate at the unloading end 322 of the second conveyor belt 320. When the accumulated products 510 clog the unloading end 322 of the second conveyor belt 320, some products 510 are squeezed into the receiving end 311 of the first conveyor belt 310, and then conveyed back to the loading end 321 of the second conveyor belt 320 through the return end 312 of the first conveyor belt 310 to continue conveying. Thus, by setting up the second conveyor belt 320, the conveying efficiency of the feeding device can be improved; by setting up the first conveyor belt 310, the second conveyor belt 320 can be assisted, thereby realizing the return of product 510, ensuring the normal operation of the feeding device, and improving the reliability of the feeding device.

[0054] The technical solution of this utility model involves setting a base 100, a material transfer component, and a material return component in a feeding device. The material transfer component is located on the base 100 and has a material transfer channel. The width of the material transfer channel is adapted to the product 510 so that the product 510 is sequentially transferred from the inlet end 211 to the outlet end 221 of the material transfer channel. The material return component is located on the base 100 and includes a first conveyor belt 310 and a second conveyor belt 320 arranged side-by-side. The return end of the first conveyor belt 310... 312 is connected to the loading end 321 of the second conveyor belt 320, and the receiving end 311 of the first conveyor belt 310 and the feeding end 211 of the material conveying channel are respectively connected to the unloading end 322 of the second conveyor belt 320, so that part of the product 510 of the unloading end 322 of the second conveyor belt 320 is conveyed to the feeding end 211 of the material conveying channel, and part of the product 510 is conveyed to the receiving end 311 of the first conveyor belt 310 and then conveyed by the return end 312 of the first conveyor belt 310 to the loading end 321 of the second conveyor belt 320. Compared with the existing feeding devices that use a single conveying path, the technical solution of this utility model is equipped with a feeding return component. When the product 510 is blocked at the junction of the feeding end 211 of the conveying channel and the unloading end 322 of the second conveyor belt 320, the blocked product 510 will re-enter the second conveyor belt 320 through the first conveyor belt 310, realizing the return of the product 510 and improving the scheduling capability of the feeding device.

[0055] Please see Figure 1In one embodiment, the feeding device further includes a partition 410 disposed between the first conveyor belt 310 and the second conveyor belt 320. The partition 410 is provided with a connecting notch 411, and the receiving end 311 of the first conveyor belt 310 is connected to the unloading end 322 of the second conveyor belt 320 through the connecting notch 411.

[0056] In one embodiment, two partitions 410 are spaced apart, one between the first conveyor belt 310 and the second conveyor belt 320, and the other between the first conveyor belt 310 and the material conveying channel. A connecting notch 411 is formed between the two partitions 410. In one embodiment, the partition 410 between the first conveyor belt 310 and the second conveyor belt 320 has a connecting opening at the end away from the material conveying channel, so that the return end 312 of the first conveyor belt can connect with the loading end 321 of the second conveyor belt 320. Of course, in other embodiments, only one partition 410 may be provided, with a connecting notch 411 corresponding to the unloading end 322 of the second conveyor belt 320 and the infeed end 211 of the material conveying channel. Here, there is no limitation on the partition 410. In one embodiment, the size of the connecting notch 411 is larger than the size of the product 510 to ensure that at least one product 510 can pass through the connecting notch 411. The specific dimensions of the connecting gap 411 can be flexibly set according to actual needs, and no specific restrictions are imposed here.

[0057] The technical solution of this utility model embodiment, by setting a partition 410 and a connecting notch 411, ensures that the second conveyor belt 320 only connects with the first conveyor belt 310 at the unloading end 322 and the loading end 321, thereby ensuring the return of product 510 and preventing product 510 normally conveyed by the second conveyor belt 320 from accidentally entering the first conveyor belt 310. This improves the scheduling capability of the loading device and enhances its reliability.

[0058] Please see Figure 1 In one embodiment, the feeding device further includes a first guide plate 420 and a second guide plate 430. The first guide plate 420 is disposed at the return end 312 of the first conveyor belt 310, and the second guide plate 430 is disposed at the unloading end 322 of the second conveyor belt 320.

[0059] The first guide plate 420 guides the product 510 from the return end 312 of the first conveyor belt 310 to the loading end 321 of the second conveyor belt 320, and the second guide plate 430 guides the product 510 from the unloading end 322 of the second conveyor belt 320 to the feed end 211 of the material transfer channel. In one embodiment, the first guide plate 420 is inclined relative to the conveying direction of the first conveyor belt 310, with one end extending to the side of the first conveyor belt 310 away from the second conveyor belt 320, and the other end extending to the loading end 321 of the second conveyor belt 320. In one embodiment, the second guide plate 430 is inclined relative to the conveying direction of the second conveyor belt 320, with one end extending to the side of the second conveyor belt 320 away from the first conveyor belt 310, and the other end extending to the feed end 211 of the material transfer channel. In one embodiment, the first guide plate 420 and the second guide plate 430 are arranged parallel to each other. Of course, in other embodiments, the extending directions of the first guide plate 420 and the second guide plate 430 may also intersect, and this is not a limitation.

[0060] The technical solution of this utility model embodiment, by setting a first guide plate 420 and a second guide plate 430, restricts the conveying path of the product 510, guides the product 510 to be conveyed along the prescribed conveying path, ensures conveying efficiency, and further improves the reliability of the feeding device.

[0061] Please see Figures 1 to 3 In one embodiment, the material transfer assembly includes a third conveyor belt 210, the feed end 211 of the third conveyor belt 210 being connected to the discharge end 322 of the second conveyor belt 320.

[0062] In one embodiment, the third conveyor belt 210 is part of the material transfer channel, and the feed end 211 of the third conveyor belt 210 is the feed end 211 of the material transfer channel. The width of the third conveyor belt 210 is adapted to the size of the product 510. In one embodiment, a partition 410 is located on one side of the feed end 211 of the third conveyor belt 210, and a limiting plate connected to the second guide plate 430 is provided on the other side of the feed end 211. The partition 410 and the limiting plate are arranged parallel to each other, and the distance between the partition 410 and the limiting plate is adapted to the size of the product 510 to restrict the product 510 from entering the material transfer channel sequentially. In one embodiment, the feed end 211 of the third conveyor belt 210 is closely connected to the discharge end 322 of the second conveyor belt 320 and is located on the same horizontal plane to ensure that the product 510 is smoothly transferred from the second conveyor belt 320 to the third conveyor belt 210. In one embodiment, the material transfer assembly further includes a first power component 230, which is disposed on the base 100 and drivenly connected to the third conveyor belt 210. The first power component 230 drives the third conveyor belt 210 to move. The first power component 230 can be a cylinder, motor, or hydraulic cylinder, etc. The first power component 230 is directly driven to the third conveyor belt 210 or driven through a gear rack, worm gear, or other means; no limitation is imposed here.

[0063] Please see Figures 1 to 3 In one embodiment, the material transfer assembly further includes a guide structure 220, which connects the third conveyor belt 210 to the feeding position, and the guide structure 220 and the third conveyor belt 210 together form a material transfer channel.

[0064] In one embodiment, the guiding structure 220 includes an inclined platform 223 and a guide groove 222. One end of the inclined platform 223 is connected to the base 100, and the other end extends to the loading position. The guide groove 222 is disposed on the inclined platform 223 and is connected to the third conveyor belt 210. In one embodiment, the discharge end 221 of the inclined platform 223 is also the discharge end 221 of the material transfer channel. The inclined platform 223 is inclined at a certain angle relative to the base 100, so that the product 510 can slide along the guide groove 222 under the action of gravity. The inclination angle of the inclined platform 223 can be flexibly set according to the actual situation, as long as it ensures that the product 510 can slide along the guide groove 222. There is no limitation here. In one embodiment, the width of the guide groove 222 is adapted to the size of the product 510 to ensure that the product 510 is sequentially conveyed from the third conveyor belt 210 to the discharge end 221 of the inclined platform 223. In one embodiment, the guide structure 220 further includes a limiting baffle 224, which is rotatably disposed at the end of the inclined platform 223 away from the base 100, and is located on opposite sides of the guide groove 222. Specifically, in one embodiment, two limiting baffles 224 are provided, located on both sides of the discharge end 221 of the inclined platform 223. Each limiting baffle 224 includes a fixed part and a movable part. The fixed part is rotatably mounted on the inclined platform 223, and the movable part can rotate around the fixed part. In one embodiment, the movable part of the limiting baffle 224 is arranged parallel to the loading position to guide the product 510 to smoothly reach the loading position. When no product 510 arrives at the discharge end 221, the movable parts of the two limit baffles 224 move closer to each other; when a product 510 arrives at the discharge end 221, under the push of the product 510, the movable parts of the two limit baffles 224 move away from each other and contact the two sides of the product 510 respectively, so that the product 510 is parallel to the tooling fixture 700 at the loading position.

[0065] Thus, product 510 enters the feed end 211 of the third conveyor belt 210 from the unloading end 322 of the second conveyor belt 320. The third conveyor belt 210 conveys product 510 to the guide chute 222. Due to the tilting platform 223 being tilted at a certain angle, product 510 will slide along the guide chute 222 to the discharge end 221 under the action of gravity. Product 510 pushes the limiting baffles 224 away from each other. The limiting baffles 224 restrict and guide product 510, so that product 510 falls smoothly onto the tooling fixture 700, completing the loading.

[0066] The technical solution of this utility model embodiment, by setting up a third conveyor belt 210, an inclined platform 223, and a guide trough 222, ensures that the product 510 arrives at the loading position sequentially. By setting up a limiting baffle 224, the position and movement of the product 510 can be restricted, guiding the product 510 to complete the loading accurately and smoothly, thereby improving the reliability of the loading device.

[0067] Please see Figure 1 and Figure 2 In one embodiment, the base 100 includes a base 110 and a side plate 120. The material transfer assembly and the material feeding return assembly are both disposed on the base 110, and the side plate 120 is movably disposed on the side of the base 110.

[0068] The base 110 provides an installation foundation for the feeding device. In one embodiment, the base 110 is used to fix or place the device in a designated position, and the side plate 120 is parallel to the conveying direction of the feeding device and abuts against the base 110. In one embodiment, a lifting slide 130 is connected to the side of the side plate 120 away from the base 100, and the lifting slide 130 drives the side plate 120 to rise and fall relative to the base 110. In one embodiment, the slider of the lifting slide 130 is fixedly connected to the side plate 120 to facilitate the lifting and lowering of the side plate 120. Of course, in other embodiments, the side plate 120 may also be movably connected to the base 110, or the side plate 120 may be directly connected to a motor, cylinder, or hydraulic cylinder, etc., without limitation. Thus, by providing a liftable side plate 120, it is possible to accommodate products 510 of different heights, thereby preventing the products 510 from falling during conveying and improving the reliability of the feeding device.

[0069] In one embodiment, the feeding device further includes a posture recognition element, which is disposed near the discharge end 221 of the material transfer channel.

[0070] In one embodiment, the attitude detection element is configured as a through-beam sensor, with the receiver and transmitter located on opposite sides of the tilting platform 223 to ensure the light beam passes through the guide groove 222. The through-beam sensor determines the attitude of the product 510 based on the order or position of the light beam being blocked. The attitude detection of the product 510 can be forward / backward, tilt angle, or overlap detection; no specific limitation is made here. Of course, in other embodiments, the attitude recognition element can also be configured as a reflective photoelectric sensor, a laser sensor, or an infrared through-beam sensor, etc.; no limitation is made here. In one embodiment, the feeding device also includes an air blowing device electrically connected to the attitude detection element. Please refer to [link to relevant documentation]. Figure 3 In one embodiment, the tilting platform 223 is provided with a mounting position 225, and an air blowing device (not shown) is provided at the mounting position 225. When the posture recognition element detects a product 510 with an incorrect posture, the air blowing device is activated to blow the product 510 out of the guide groove 222. Of course, in other embodiments, a pushing device or a clamping device may also be provided to discharge the product 510 with an incorrect posture from the guide groove 222; this is not a limitation. Thus, by setting a posture detection element, intelligent correction of the feeding device is achieved, thereby improving the reliability of the feeding device.
