Description

Technical Field

[0001] The utility model relates to the field of conveying, in particular to a belt rejection conveyor. Background Art

[0002] In the actual production process, it is often necessary to classify the products on the conveyor line according to weight, metal content or size. At present, after the inspection is completed, different categories of products are mainly grabbed by robots to different conveyor lines or different placement areas, which has certain requirements for the space height. In addition, different robots need to be configured for products of different shapes and sizes, resulting in excessively high equipment costs. Furthermore, when there are many categories, the robot needs to have sufficient travel, resulting in a relatively large space.

[0003] Therefore, it is urgent to design a device that does not rely on a robot and can perform classification and removal. Summary of the invention

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a belt rejection conveyor, which can complete the classification and rejection of products without relying on a robot, has strong versatility, and is not restricted by space height and area.

[0005] In order to solve the above technical problems, the technical solution of the utility model is a belt rejection conveyor, comprising:

[0006] At least two roller conveyors are arranged in parallel along the X-axis direction and are used to convey the product along the Y-axis direction;

[0007] A belt conveyor having a plurality of conveyor belts arranged in parallel and spaced apart in the Y-axis direction, for conveying products in the X-axis direction, each conveyor belt passing through all roller conveyors in the X-direction and being located in the gap between adjacent conveyor rollers of the roller conveyors;

[0008] The lifting drive mechanism is connected to the belt conveyor and is used to drive the belt conveyor to rise until the conveying belt is higher than the conveying roller or to descend until the conveying belt is lower than the conveying roller.

[0009] In order to further prevent the conveyed product from slipping on the conveying roller, the outer peripheral wall of the conveying roller is provided with a plurality of convex ribs extending along the X-axis direction along the circumferential direction.

[0010] In order to further facilitate the spatial coordination between the conveyor belt and the roller conveyor, the two sides of the frame of the roller conveyor are comb-shaped, the conveyor rollers are rotatably supported on the comb teeth of the frame, and the conveyor belt is located in a comb groove formed by adjacent comb teeth.

[0011] In order to further improve the carrying capacity of the belt conveyor and prevent the conveyor belt from deviating, the belt conveyor has a nylon guide rail corresponding to the conveyor belt one by one, and the upper part of the conveyor belt is slidably fitted in the nylon guide rail.

[0012] In order to further improve the strength of the entire nylon guide rail, all sections of the nylon guide rail that do not overlap with the roller conveyor are fixedly connected by a reinforcing beam extending along the Y axis.

[0013] Furthermore, both ends of the belt conveyor extend outward beyond the outermost roller conveyor.

[0014] Furthermore, the lifting drive mechanism includes four cylinders, each of which supports a corner of the belt conveyor.

[0015] In order to keep the conveyor belt taut at all times, the belt conveyor also has a plurality of unpowered pressure rollers pressed on the lower half of the conveyor belt, and the unpowered pressure rollers can slide up and down driven by the conveyor belt.

[0016] After adopting the above technical scheme, after the product is transported to one of the roller conveyors by the external conveying mechanism, the belt conveyor rises under the action of the lifting drive mechanism, holds up the product, and transports the product to other roller conveyors along the X-axis direction, and then descends under the action of the lifting drive mechanism, so that the product falls on other roller conveyors. The belt conveyor can also directly transport the product to fall from its end or enter other external conveying mechanisms. In this way, the classification or rejection of the products can be realized without the need for a robot, which is convenient and trouble-free, has strong versatility, and is not limited by space height and area.

[0021] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0022] like Figure 1 , 2 , 3, a belt rejection conveyor, comprising:

[0023] At least two roller conveyors 1 are arranged in parallel along the X-axis direction and are used to convey products along the Y-axis direction;

[0024] The belt conveyor 2 has a plurality of conveyor belts arranged in parallel and at intervals in the Y-axis direction, and is used to convey products along the X-axis direction, each conveyor belt passes through all roller conveyors 1 in the X-direction, and is located in the gap between adjacent conveyor rollers 11 of the roller conveyor 1;

[0025] The lifting drive mechanism 3 is connected to the belt conveyor 2 and is used to drive the belt conveyor 2 to rise until the conveying belt is higher than the conveying roller 11 or to descend until the conveying belt is lower than the conveying roller 11.

[0026] Specifically, after the product is transported to one of the roller conveyors 1 by the external conveying mechanism, the belt conveyor 2 rises under the action of the lifting drive mechanism 3, lifts the product, and transports the product to other roller conveyors 1 along the X-axis direction, and then descends under the action of the lifting drive mechanism 3, so that the product falls on other roller conveyors 1. The belt conveyor 2 can also directly transport the product to fall from its end or enter other external conveying mechanisms. In this way, the classification or rejection of the product can be achieved. The standard for classification or rejection can be product weight, size, or metal content, which is not limited here. The belt rejection conveyor in this embodiment mainly classifies or rejects the product to the corresponding position based on the detection and classification results of the previous process, and then enters the subsequent equipment. No robot is required, which is convenient and trouble-free, has strong versatility, and is not limited by spatial height and area.

[0027] In this embodiment, two roller conveyors 1 are provided, and the entire belt rejection conveyor can divide the products into four categories: Figure 1 For example, if the product enters the roller conveyor 1 on the left, the product can continue to be conveyed along the roller conveyor 1 on the left, or the product can be conveyed to the roller conveyor 1 on the right through the belt conveyor 2, or the product can be conveyed through the belt conveyor 2 to drop from the left end of the belt conveyor 2, or the product can be conveyed through the belt conveyor 2 to drop from the right end of the belt conveyor 2.

[0028] In one embodiment, Figure 1 , 2 As shown in FIG. 3 , the outer peripheral wall of the conveying roller 11 is provided with a plurality of convex ribs 111 extending along the X-axis direction along the circumferential direction.

[0029] Specifically, the convex ribs 111 are provided to effectively prevent the product from slipping on the conveying rollers 11 of the roller conveyor 1, thereby ensuring that the product is effectively conveyed.

[0030] In one embodiment, Figure 1 , 2 As shown in FIG. 3 , both sides of the frame 12 of the roller conveyor 1 are in a comb shape, the conveying rollers 11 are rotatably supported on the comb teeth 121 of the frame 12 , and the conveying belt is located in a comb groove formed by adjacent comb teeth 121 .

[0031] Specifically, such an arrangement facilitates the spatial coordination of the belt conveyor 2 and the roller conveyor 1 and prevents interference with each other.

[0032] In one embodiment, Figure 1 , 2 As shown in FIG. 3 , the belt conveyor 2 has a nylon guide rail 21 corresponding to the conveying belt one by one, and the upper part of the conveying belt is slidably fitted in the nylon guide rail 21 .

[0033] Specifically, the nylon guide rail 21 can support and restrain the conveyor belt, thereby improving the carrying capacity of the conveyor belt and effectively preventing the conveyor belt from deviating.

[0034] In one embodiment, Figure 1 , 2 As shown in Figures 3 and 4, the sections of all nylon guide rails 21 that do not overlap with the roller conveyor 1 are fixedly connected by reinforcing beams 22 extending along the Y-axis.

[0035] Specifically, the reinforcing beam 22 connects the multiple nylon guide rails 21 as a whole, plays a restraining role, and prevents a single nylon guide rail 21 from deflecting. At the same time, it also enhances the strength of the nylon guide rail 21 and improves the bearing capacity of the nylon guide rail 21.

[0036] In one embodiment, Figure 1 , 2 As shown in 3, both ends of the belt conveyor 2 extend outward beyond the outermost roller conveyor 1.

[0037] Such an arrangement ensures that the belt conveyor 2 can effectively convey the product to prevent it from falling from its end or entering other external conveying mechanisms, preventing the product from accidentally falling on the edge of the roller conveyor 1, thereby improving the stability and reliability of the entire belt rejection conveyor.

[0038] In one embodiment, Figure 1 , 2 As shown in Figure 3, the lifting drive mechanism 3 includes four cylinders, each of which supports a corner of the belt conveyor 2.

[0039] The structure of the lifting drive mechanism 3 is arranged in this way, which can ensure that each part of the belt conveyor 2 can be lifted and lowered evenly to avoid tilting.

[0040] In one embodiment, Figure 1 , 2 As shown in FIG. 3 , the belt conveyor 2 also has a plurality of unpowered pressure rollers 23 pressed on the lower half of the conveying belt. The unpowered pressure rollers 23 can slide up and down driven by the conveying belt.

[0041] Specifically, the unpowered pressure roller 23 presses on the lower half of the conveyor belt and adjusts the tension of the conveyor belt by its own gravity to ensure that the conveyor belt is in a tensioned state for a long time, thereby effectively conveying the product along the X-axis direction.

[0042] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
