[0002] Flange, also known as flange flange or flange, is one of the indispensable parts in mechanical equipment. The cylindrical steel column is cut into flange blanks of similar size by cutting equipment. Due to the inevitable errors in cutting, the weight of each flange blank is different, either heavier than the standard weight or lighter than the standard weight. In this case, before the flange blank is finely processed, it is necessary to screen and classify the flange blanks by weight, and screen out the flange blanks that do not meet the required weight. In the current existing technology, the screening of flange blanks is basically done manually by weighing the flange blanks one by one through weighing equipment and manually screening. Due to the heavy weight of the flange, there is a certain labor intensity for manual labor. At the same time, manual weighing is not efficient, and it is easy to make mistakes during screening.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 and Figure 2 As shown, a preferred embodiment of the utility model proposes an automatic weighing and screening system for flanges, which mainly includes modules such as a post-shearing conveyor line 7, an elevator 6, a guide conveyor line 1, a limit conveyor line 2, a weighing conveyor line 3, and a screening conveyor line 4, wherein the post-shearing conveyor line 7 adopts a roller conveyor line for conveying flange blanks formed after cutting. The post-shearing conveyor line 7 is perpendicular to the elevator 6, and one side of the post-shearing conveyor line 7 has a discharge port, which is connected to the feed port of the elevator 6. The front end (i.e., the feed end) of the post-shearing conveyor line 7 is usually connected to the cutting equipment, and the cut flange blanks will be conveyed from the post-shearing conveyor line 7 to the elevator 6.

[0025] refer to Figure 4 A guide plate 12 is installed opposite to the discharge port of the post-shear conveyor line 7. The guide plate 12 is arranged to intercept the conveying direction of the post-shear conveyor line 7 and forms a certain angle with the conveying direction, so as to guide the flange blank to enter the elevator 6 from the discharge port of the post-shear conveyor line 7 on the side. The guide plate 12 is rotatable, so the angle between the guide plate 12 and the conveying direction of the post-shear conveyor line 7 is adjustable.

[0026] The discharge end of the elevator 6 is connected to the guide conveyor line 1. The elevator 6 will lift the scattered flange blanks layer by layer, and lift the flange blanks in an orderly manner to the linear conveyor belt at the top of the elevator 6. The flange blanks will be arranged linearly on the linear conveyor belt, and finally conveyed to the guide conveyor line 1 one by one.

[0027] like Figure 2As shown, the guide conveyor line 1 adopts a chain conveyor line, which drives the chain to rotate through a motor to drive the flange blank to be conveyed backward. Limiting blocks are set on both sides of the guide conveyor line 1, and there is a channel for the flange blank to pass through between the two limiting plates. The front ends of the two limiting plates are bent to the opposite side to form an "eight"-shaped structure, which is used to guide the flange blank into the guide conveyor line 1. At the same time, the two limiting plates will limit the flange blank to ensure that the flange blank is located in the middle of the guide conveyor line 1. The spacing between the two limiting plates is adjustable to meet the limitation of flange blanks of different diameters.

[0028] refer to Figure 5 A driving base 8 is provided between the guide conveyor line 1 and the screening conveyor line 4, for installing the limit conveyor line 2 and the weighing conveyor line 3. There are two limit conveyor lines 2 and two weighing conveyor lines 3, one limit conveyor line 2 and one weighing conveyor line 3 form a group, and the two groups of conveyor lines are parallel to each other. The head and tail ends of the limit conveyor line 2 are respectively docked with the guide conveyor line 1 and the weighing conveyor line 3. Two slides are installed on the driving base 8, and each slide is installed with a limit conveyor line 2 and a weighing conveyor line 3. The slide is connected to the driving base 8 in a horizontal sliding manner, and the driving base 8 is connected to the slide drive by a screw rod. The screw rod is driven to rotate by a motor to drive the two slides to move, thereby switching the two groups of conveyor lines.

[0029] The specifications of the two position limiting transmission lines 2 are different, one is used for position limiting transmission of large-sized flange blanks, and the other is used for position limiting transmission of small-sized flange blanks. The specifications of the two weighing transmission lines 3 are also different, one is used for weighing large-sized flange blanks, and the other is used for weighing small-sized flange blanks.

[0030] Baffles are provided on both sides of the position-limiting conveyor line 2 for precise position limiting of the flange blank. The distance between the two baffles is slightly larger than the diameter of the flange blank, and the distance between the two baffles can be fine-tuned. The length of the position-limiting conveyor line 2 is greater than the length of the weighing conveyor line 3. The weighing conveyor line 3 weighs only one flange blank at a time, while the position-limiting conveyor line 2 can temporarily store multiple flange blanks.

[0031] The weighing conveyor line 3 is composed of a conveyor line body and a weighing device (not shown in the figure). The weighing device is located at the bottom of the conveyor line body, and the conveyor line body is fixed on the weighing device. The weighing device can weigh the conveyor line body and the products on the conveyor line body as a whole. The weighing device can use a pressure sensor 9 or an electronic scale, and the weighing data will be uploaded to the system.

[0032] The screening conveyor line 4 is connected to the weighing conveyor line 3. Each time the weighing conveyor line 3 weighs a flange blank, it will convey the flange blank to the screening conveyor line 4. At the same time, the limiting conveyor line 2 will convey a flange blank to the weighing conveyor line 3.

[0033] Sensors 9 for detecting the moving position of the flange blank are installed on the sides of the position limiting conveying line 2, the weighing conveying line 3 and the screening conveying line 4.

[0034] like Figure 2 As shown, the screening conveyor line 4 adopts a chain conveyor line, baffles are also provided on both sides of the screening conveyor line 4, and two discharge ports are provided on both sides of the screening conveyor line 4, and the discharge ports on both sides are arranged in a left-right staggered manner, and a pushing mechanism 11 is provided opposite to each discharge port, which is used to push the flange blank out of the screening conveyor line 4 from the side. A discharge port is provided at the end of the screening conveyor line 4, and the pushing mechanism 11 is not provided at the discharge port.

[0035] A guide plate 10 is installed at each of the five material outlets, and the guide plate 10 is tilted downward. A material box 5 is placed below the guide plate 10, and there are five material boxes 5 in total. Two of the five material boxes 5 are used to store flange blanks with qualified weight (i.e., standard weight), two of the material boxes 5 are used to store flange blanks heavier than the standard weight and lighter than the standard weight, respectively, and the other material box 5 is used to store waste materials.

[0036] A sensor 9 is installed near the discharge port on the screening conveyor line 4 to detect whether the flange blank has reached the discharge port. Once the flange waste is detected to have reached the corresponding discharge port, the pushing mechanism 11 will push the flange blank onto the guide plate 10 and flow into the material box 5 along the guide plate 10.

[0037] refer to Figure 3 The pushing mechanism 11 is composed of a pushing cylinder 111 and a pushing plate 112. The pushing cylinder 111 is horizontally fixed opposite to the discharge port. The pushing plate 112 is fixedly connected to the output end of the pushing cylinder 111. The pushing cylinder 111 controls the movement of the pushing plate 112 to push the flange blank onto the guide plate 10.

[0038] The system will cooperate with the sensor 9 on the screening conveyor line 4 according to the uploaded weighing information to control the flange blank to move to the corresponding discharge port position to complete the screening and unloading of the flange blank.

[0039] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
