Description

Technical Field

[0001] This utility model relates to the field of stamping parts production technology, specifically, it demonstrates an automatic sorting line for stamping parts. Background Technology

[0002] Stamped parts are workpieces produced by stamping with a stamping machine. During the stamping process, stamped parts may vary in size and weight, requiring sorting to select qualified products. The traditional method is manual weighing and sorting, which wastes a lot of labor and is inefficient. Therefore, it is necessary to use an automatic sorting device to sort them. Utility Model Content

[0003] The purpose of this invention is to provide an automatic sorting line for stamped parts, which has a simple and reliable structure and improves efficiency.

[0004] The technical solution is as follows:

[0005] An automatic sorting line for stamped parts includes a feeding roller conveyor line arranged in a T-shape on a frame, a first weighing screw conveyor, a second weighing screw conveyor, a good product unloading roller conveyor line, a defective product unloading roller conveyor line, and a pushing assembly. The first and second weighing screw conveyors are arranged sequentially between the feeding roller conveyor line and the good product unloading roller conveyor line. The defective product unloading roller conveyor line is arranged vertically on one side of the front of the good product unloading roller conveyor line. The pushing assembly is arranged on the other side of the front of the good product unloading roller conveyor line and can move towards the inlet direction of the defective product unloading roller conveyor line.

[0006] Optionally, a stop assembly located below the end of the feeding roller conveyor line is also included to stop the next stamping part when the previous stamping part flows out of the feeding roller conveyor line. The flow speed of the stamping parts can be adjusted according to production line requirements and capacity. If the No. 1 and No. 2 weighing screw conveyors require a longer time to weigh the stamping parts, the stop assembly can temporarily stop or slow down the flow of stamping parts on the feeding roller conveyor line, thereby ensuring the working balance of the slitting line.

[0007] The stop assembly includes a stop cylinder vertically mounted on the frame and a stop rod vertically connected to the stroke end of the stop cylinder. The stop rod can pass upward through the feeding roller conveyor line. The stop cylinder drives the stop rod to move up and down relative to the feeding roller conveyor line to block the stamped parts on the feeding roller conveyor line or allow them to pass.

[0008] Optionally, the pushing assembly includes a pushing cylinder horizontally disposed on the good product unloading roller conveyor line, and a pushing plate vertically connected to the stroke end of the pushing cylinder. The pushing plate can extend and retract forward and backward toward the entrance direction of the defective product unloading roller conveyor line. The pushing cylinder drives the pushing plate to move back and forth relative to the entrance direction of the defective product unloading roller conveyor line, so as to push the defective stamped parts from the good product unloading roller conveyor line to the defective product unloading roller conveyor line.

[0009] The pusher plate has a recessed contact groove in the middle of its front part. This allows for better contact with the wall surface of the stamped part, increasing the contact area and ensuring that there is no accidental slippage between the pusher plate and the stamped part during the pushing process.

[0010] Optionally, each of the frames is equipped with a first material sensor and a second material sensor, respectively, facing the No. 1 and No. 2 weighing screw conveyors, via two sets of uprights. The first / second material sensors automatically detect whether stamped parts are being conveyed onto the No. 1 / No. 2 weighing screw conveyor, thus activating the No. 1 / No. 2 weighing screw conveyor.

[0011] Optionally, the bottom of the frame is equipped with several wheels to improve the mobility and flexibility of the sorting line, enabling it to move easily in different working environments and adapt to the needs of various work scenarios.

[0012] Compared with existing technologies, the advantages of this invention are as follows: It utilizes a feeding roller conveyor line to achieve orderly feeding of batch stamped parts. The stamped parts are weighed twice using a first-stage weighing screw conveyor and a second-stage weighing screw conveyor, and the average of the two weighings is taken. The weighed stamped parts are then sequentially fed to the good-product unloading roller conveyor line. If the measured average value meets the requirements, the stamped parts continue to flow on the good-product unloading roller conveyor line to complete unloading. Conversely, if the measured average value does not meet the requirements, the pushing component pushes the stamped parts from the good-product unloading roller conveyor line to the defective-product unloading roller conveyor line for unloading. Compared with traditional manual weighing and sorting methods, this invention has high working efficiency, a simple and reliable structure, a more complete design, avoids human error, and improves sorting efficiency.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides an automatic sorting line for stamped parts, which solves the technical problems mentioned in the background art. For example... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, specifically, it mainly includes a frame 1, on which a feeding roller conveyor line 2, a first weighing screw conveyor 3, a second weighing screw conveyor 4, a good product unloading roller conveyor line 5, a defective product unloading roller conveyor line 6, and a pushing assembly 7 are arranged in a T-shape. The first weighing screw conveyor 3 and the second weighing screw conveyor 4 are arranged sequentially between the feeding roller conveyor line 2 and the good product unloading roller conveyor line 5, while the defective product unloading roller conveyor line 6 is arranged vertically. On one side of the front of the good product unloading roller conveyor line 5, the pushing assembly 7 is located on the other side of the front of the good product unloading roller conveyor line 2, and can move towards the entrance of the defective product unloading roller conveyor line 6; in specific implementation, the conveying trajectory surfaces of the feeding roller conveyor line 2, the first weighing screw conveyor 3, the second weighing screw conveyor 4, the good product unloading roller conveyor line 5, and the defective product unloading roller conveyor line 6 are almost on the same plane, ensuring that the stamped parts can flow stably between them.

[0020] It should be noted that the feeding roller conveyor line 2, the good product unloading roller conveyor line 5, and the defective product unloading roller conveyor line 6 are all based on existing technology and mainly consist of drive rollers, frame, drive unit, etc.; the No. 1 weighing screw conveyor 3 and the No. 2 weighing screw conveyor 4 are also based on existing technology and mainly consist of a steady flow feeding screw, weighing bridge, geared motor, weighing sensor, speed sensor, weighing control instrument and electrical control system, etc., used for material conveying and weight detection through the weighing bridge.

[0021] When the automatic sorting line is in use: the feeding roller conveyor line 2 realizes the orderly feeding of batch stamped parts, and then the first weighing screw conveyor 3 and the second weighing screw conveyor 4 are used to weigh the stamped parts twice, and the average value of the two is taken. The stamped parts after weighing are sent to the good product unloading roller conveyor line 5 in sequence. If the measured average value data meets the requirements, the stamped parts continue to flow on the good product unloading roller conveyor line 5 and the unloading is completed. Otherwise, if the measured average value data does not meet the requirements, the pushing component 7 pushes the stamped parts from the good product unloading roller conveyor line 5 to the defective product unloading roller conveyor line 6 for unloading.

[0022] In this embodiment, a stop assembly 8 is also included below the end of the feeding roller conveyor line 2, used to stop the next stamped part when the previous stamped part flows out of the feeding roller conveyor line 2. The flow speed of the stamped parts is adjusted according to the production line requirements and capacity. If the No. 1 weighing screw conveyor and the No. 2 weighing screw conveyor need a long time to weigh the stamped parts, the stop assembly can temporarily stop or slow down the flow of stamped parts on the feeding roller conveyor line, thereby ensuring the working balance of the slitting line.

[0023] The stop assembly 8 includes a stop cylinder 81 vertically mounted on the frame 1 and a stop rod 82 vertically connected to the stroke end of the stop cylinder 81. The stop cylinder 81 is located below the feeding roller conveyor line 2, and the stop rod 82 can pass upward through the feeding roller conveyor line 2. The stop cylinder drives the stop rod to move up and down relative to the feeding roller conveyor line to block the stamped parts on the feeding roller conveyor line or allow them to pass.

[0024] In this embodiment, the pushing assembly 7 includes a pushing cylinder 71 horizontally mounted on the good product unloading roller conveyor line 5, and a pushing plate 72 vertically connected to the stroke end of the pushing cylinder 71. The pushing plate 72 can extend and retract forward and backward toward the entrance direction of the defective product unloading roller conveyor line 6. The pushing cylinder drives the pushing plate to move back and forth relative to the entrance direction of the defective product unloading roller conveyor line, so as to push the defective stamped parts from the good product unloading roller conveyor line to the defective product unloading roller conveyor line.

[0025] The pusher plate 72 has a recessed contact groove 73 in the middle of its front part. The contact groove allows for better contact with the wall surface of the stamped part, increasing the contact area and ensuring that there is no accidental slippage between the pusher plate and the stamped part during the pushing process.

[0026] In this embodiment, each of the frame 1 has a first material sensor 13 and a second material sensor 14 mounted on two sets of uprights 12, respectively facing the No. 1 weighing screw conveyor 3 and the No. 2 weighing screw conveyor 4. The first and second material sensors can be laser sensors. The first and second material sensors can automatically detect whether there are stamped parts being conveyed to the No. 1 and No. 2 weighing screw conveyors, so that the No. 1 and No. 2 weighing screw conveyors can start working.

[0027] In this embodiment, several wheels 11 are distributed at the bottom of the frame 1. These wheels improve the mobility and flexibility of the sorting line, allowing it to move easily in different working environments and adapt to various work scenarios.

[0028] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
