DETAILED DESCRIPTION

[0051] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0052] Please refer to Figures 1-3 , the present application provides the following technical solutions:

[0053] A circulating feeding device, comprising a feeding unit 1, a first conveying unit 2, a second conveying unit 3 and a return material unit 4. The feeding unit 1 is used for containing and conveying materials, and the feeding unit 1 takes the vibrating disc 11 as the basis of the material output structure. The feeding end of the first conveying unit 2 is arranged corresponding to the discharging end of the feeding unit 1, the feeding end of the second conveying unit 3 is arranged corresponding to the discharging end of the first conveying unit 2, and the feeding end of the return material unit 4 is arranged corresponding to the discharging end of the second conveying unit 3. The return material unit 4 returns the materials to the vibrating disc 11 of the feeding unit 1.

[0054] The cycle feeding device works. The vibration disc 11 outputs the material to the first conveying unit 2, which conveys the material, and workers can take the material for processing on its conveying path. The first conveying unit 2 conveys the material to the second conveying belt unit 3, which receives the material conveyed by the first conveying unit 2 and transmits it to the return material unit 4. The return material unit 4 returns the material to the vibration disc 11, forming a circulating material conveying line.

[0055] The advantage of this mode is that the entire material conveying line is a circulating material line, and the vibration disc for feeding only needs to be provided with a small amount on the feeding side of the first conveying unit 2. In the drawings of the present scheme, one is shown, which can be increased according to actual conditions. Because the present scheme is a circulating conveying line, the worker's taking speed does not need to be considered, and a relatively high material feeding speed can be maintained. Even if the worker cannot take it in time, the material will return to the feeding unit 1, and the conveying line will not be blocked. Because the feeding unit 1 of the present scheme only needs to be provided at the feeding end of the first conveying unit 2, the subsequent material replenishment is also simpler, which can be completed by manual or other equipment at a fixed position.

[0056] On the basis of the above-mentioned embodiment, the feeding unit 1 comprises a feeding rack 12, which is a vertical rack body comprising a rectangular rack body and a right-angled triangular rack body. The rectangular rack body is fixedly provided with the vibration disc 11 above, and the right-angled triangular rack body is provided on one side of the rectangular rack body. The triangular rack body is used to connect the return material conveying belt 41 of the return material unit 4.

[0057] The feeding unit 1 further comprises a distance separating mechanism 13, which is arranged between the discharge end of the vibration disc 11 and the first conveying unit 2. The distance separating mechanism 13 can periodically convey the material output by the vibration disc 11 to the first conveying unit 2. By periodically outputting the material of the vibration disc 11, the material transferred to the first conveying unit 2 is left with a distance, which is convenient for workers to take.

[0058] On the basis of the above-mentioned embodiment, referring to Figure 4The scheme gives a specific implementation of the distance separating mechanism 13, which includes a distance separating groove 131, a distance separating disc 132 and a distance separating chute 133. The distance separating groove 131 is a semicircular arc-shaped groove body as a whole, and one side of the groove body is communicated with the discharge end of the vibrating disc 11, and the connection serves as the feeding side of the distance separating groove 131. The distance separating disc 132 is rotatably connected in the distance separating groove 131, and the central axis of the distance separating disc 132 is connected with a servo motor, which drives the distance separating disc 132 to rotate periodically. The edge of the distance separating disc 132 is provided with a plurality of notches, which are arranged in a circumferential array and are uniformly distributed. The shape of the notches corresponds to the material to be conveyed, and the notches form a nearly wavy structure. Each notch can correspond to a material to be pushed. The distance separating chute 133 is connected to the side of the distance separating groove 131 away from the vibrating disc 11, one end of the distance separating chute 133 is communicated with the distance separating groove 131, and the other end is arranged towards the first conveying unit 2. The distance separating chute 133 can be arranged at the diameter position of the circular arc formed by the distance separating groove 131.

[0059] Through the structure of the scheme, the material output by the vibrating disc 11 is accumulated on the feeding side of the distance separating groove 131. With the rotation of the distance separating disc 132, the material enters the notch above it one by one, and rotates synchronously with the distance separating disc 132. After the material rotates to the position of the distance separating chute 133, it is separated from the distance separating disc 132 and falls from the distance separating chute 133 into the first conveying unit 2.

[0060] As a further optimization of the scheme, a waste chute is arranged on one side of the distance separating chute 133, that is, the side away from the arc-shaped part of the distance separating groove 131, and a distance is left between the distance separating disc 132 and the waste chute. Some materials may not be able to normally slide off the distance separating chute 133 due to the problem of being difficult to determine. Such materials will rotate to above the waste chute with the distance separating disc 132. Because of the distance between the upper surface of the waste chute and the distance separating disc 132, the bottom surface of the material loses support and can fall off the distance separating disc 132 and enter the waste chute. A basket is placed on the discharge side of the waste chute for collection.

[0061] On the basis of the above-mentioned embodiment, the first conveying unit 2 and the second conveying unit 3 are both conveying belt type conveying structures; the present circulating feeding device further comprises a conveying frame 5, which is a vertically arranged frame body including a base frame and a plurality of columns. The base frame only needs to be stably placed on the ground. The first conveying unit 2 and the second conveying unit 3 are fixedly connected with the conveying frame 5 through the columns, and the feeding frame 12 is arranged on one side of the conveying frame 5. The first conveying unit 2 and the second conveying unit 3 are arranged in a vertical direction. The first conveying unit 2 is located directly above the second conveying unit 3.

[0062] The drawings of the present scheme are given in an implementation form for the convenience of display. The volume of the conveying frame 5 can be changed in consideration of the actual production operation environment. In the case of sufficient space, the workstations of the workers can be arranged on the side of the first conveying unit 2 and the side of the second conveying unit 3.

[0063] On the basis of the above-mentioned embodiment, the first conveying unit 2 comprises a first conveying belt 21, which is a straight conveying belt in the form of a chain plate. First conveying side plates 22 are arranged on both sides of the first conveying belt 21, and the first conveying side plates 22 are fixedly connected to the upper part of the conveying frame 5. The first conveying side plates 22 on both sides can adopt the same structure or different structures. For example, one side adopts a straight plate body, and the upper edge of the plate body is slightly higher than the upper surface of the first conveying belt 21. The other side adopts a folded plate structure to form a bent protective plate body above the first conveying belt 21.

[0064] In addition, referring to Figure 5 , the first conveying unit 2 is further provided with a conveying adjusting piece 23, one side of the conveying adjusting piece 23 is fixedly connected to the first conveying side plate 22, and the conveying adjusting piece 23 extends towards the upper side of the first conveying belt 21; the conveying adjusting piece 23 can adjust the position of the material on the first conveying belt 21. The present scheme gives a specific structure form of the conveying adjusting piece 23, which comprises a receiving part 231 and a guide part 232. The receiving part 231 is a "L"-shaped plate body, and the opening thereof corresponds to one end of the distance slide 133 towards the first conveying belt 21. The two folded plates of the "L"-shaped plate body block the material falling from the distance slide 133, preventing it from separating from the first conveying belt 21 due to inertia. One side of the "L"-shaped plate body structure is detachably connected to the first conveying side plate 22 through a connecting structure. The guide part 232 is arranged on the side of the receiving part 231 corresponding to the conveying direction of the first conveying belt 21, and the guide part 232 is an inclined plate. The material moves along the inclined plate of the guide part 232 under the drive of the first conveying belt 21, so that the material is arranged in order on the first conveying belt 21. On the one hand, it is convenient for workers to take, and on the other hand, if an automatic picking device such as a mechanical arm is introduced, it is also convenient for it to position and grasp.

[0065] A first transition piece 24 is arranged at the discharge end of the first conveying unit 2, which is a chute structure arranged obliquely, with the high horizontal end located at the discharge end of the first conveying belt 21 and the low horizontal end located above the second conveying belt 31 of the second conveying unit 3.

[0066] On the basis of the above-mentioned embodiment, referring to Figure 6The second conveying belt 31 of the second conveying unit 3 is also a straight chain plate conveying belt. Similar to the first conveying unit 2, the second conveying side plates 32 are arranged on both sides of the second conveying belt 31, and the second conveying side plates 32 are fixedly connected with the conveying frame 5. The return adjusting piece 33 is arranged at the position of the first transition piece 24 close to the second conveying belt 31, the return adjusting piece 33 is fixedly connected with the second conveying side plate 32, and the return adjusting piece 33 extends towards the upper side of the second conveying belt 31, so that the return adjusting piece 33 can prevent the material falling from the first transition piece 24 from separating from the second conveying belt 31. The return transition piece 33 includes a door-shaped cover body which is arranged above the second conveying belt 31, and the cover body does not need to be too long, and is greater than two to three lengths of the conveyed material. A baffle is arranged on the side of the cover body close to the first transition piece 24, the baffle is an inclined plate which is parallel to the first transition piece 24, and the lower edge of the baffle is fixedly connected with the first transition piece 24. Through the return adjusting piece 33, the material falling from the first transition piece 24 can be effectively buffered and limited, so that the material is prevented from separating from the second conveying belt 31 due to inertia.

[0067] On the basis of the above-mentioned embodiments, the return material unit 4 includes an inclined return conveying belt 41, the return conveying belt 41 adopts a structure form of a flexible conveying belt combined with a conveying plate, the conveying plate is perpendicular to the belt body of the conveying belt, the feeding end of the return conveying belt 41 is located below the discharging end of the second conveying belt 31, and the discharging end is located above the vibration disc 11. The return material receiving piece 42 is arranged below the discharging end of the second conveying belt 31, and the return material receiving piece 42 is a hopper.

[0068] The second conveying unit 3 further includes a return material transition piece 34 arranged between the second conveying belt 31 and the return material receiving piece 34, the return material transition piece 34 adopts a chute structure of a horn mouth structure, and the material in the second conveying belt 31 is guided into the return material receiving piece 34.

[0069] After the material falls into the return material receiving piece 42, the material is driven to a high position along with the movement of the return conveying belt 41, and then falls into the vibration disc 11 and is continuously output by the vibration disc 11.
