Description

Technical Field

[0001] This application belongs to the technical field of corner protector feeding equipment, specifically a corner protector feeding mechanism for an automatic packaging system for sheet rolls. Background Technology

[0002] Corner protectors are a common protective material used in packaging and construction, primarily to protect the edges and corners of products from damage during transportation and handling. In traditional sheet and roll packaging, each step of corner protector transportation and installation is largely done manually. This manual operation is not only inefficient but also prone to inconsistent packaging quality due to human error, increasing production costs and material waste. With technological advancements, manual loading is no longer sufficient for current automated production needs and is gradually moving towards automation. Existing automated corner protector loading equipment requires self-adaptive alignment devices to identify the corner protector's direction, resulting in complex structures and high operating costs. Furthermore, existing vibratory feeders struggle to properly arrange and transport corner protectors, and they are prone to tipping over during ascent, affecting loading efficiency. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of existing technologies by designing a corner protector feeding mechanism for an automatic plate and coil packaging system through a combination of a hopper, vibratory feeder, linear feeder, and mechanical gripper. This mechanism enables automatic feeding and transfer of corner protectors, significantly improving production efficiency and safety, reducing manual operation and labor intensity. Simultaneously, precise mechanical control minimizes damage to material edges and corners during the bundling process, protecting the integrity of the material. This makes operation simpler, more adaptable, and effectively enhances the overall performance of the automatic plate and coil packaging system.

[0015] Compared with the prior art, this application has the following beneficial effects:

[0016] 1. This application achieves automatic feeding and transfer of corner protectors by using a combination of hopper, vibratory feeder, linear feeder and mechanical gripper, which significantly improves production efficiency and safety, reduces manual operation and labor intensity.

A discharge port is located at the bottom of the side wall of the hopper 1, and a vibratory feeder 2 is located below the discharge port. The vibratory feeder 2 arranges the corner protectors 6 and transfers the arranged corner protectors 6 to a linear feeder 5 located at the discharge end of the vibratory feeder 2. The linear feeder 5 conveys the corner protectors 6 to a corner protector positioning groove 502. A mechanical gripper 4 is located at the end of the linear feeder 5, and the mechanical gripper 4 is used to grip the corner protectors 6 located in the corner protector positioning groove 502. The hopper 1, vibratory feeder 2, mounting platform 3, and mechanical gripper 4 are all mounted on the mounting platform 3, which is used to connect to the automatic plate and coil packaging system.

[0029] As a preferred method, such as Figure 3-4 As shown, the vibratory feeder 2 includes a base 204, inside which a pulse electromagnet is installed to make the hopper 203 vibrate vertically. A mounting plate 205 is fixedly installed at the bottom of the base 204, and the mounting plate 205 is fixed to the mounting platform 3 by bolts. The hopper 203 is installed at the top of the base 204, and the bottom center of the hopper 203 has an inverted conical structure to facilitate the corner protectors 6 falling to the bottom edge. The main components of the base 204, mounting plate 205, and hopper 203 are readily available commercial products, and their specific structures will not be described in detail here.

[0030] As a preferred embodiment, a spiral 202 and a trough 208 are arranged opposite each other at the bottom edge of the hopper 203. The spiral 202 is connected to the hopper 203, and the bottom end of the trough 208 is located above the bottom surface of the hopper 203, so that the corner protector 6 can move upward along the spiral 202. The end of the trough 208 is connected to the linear feeder 5. A guide block 201 is provided in the middle of the upper part of the trough 208. A gap is left between the guide block 201 and the side wall of the hopper 203 to match one side wall of the corner protector 6, so that the corner protector 6 can be locked between the guide block 201 and the side wall of the hopper 203 and move upward.

[0031] As a preferred method, the top of the spiral 202 is located directly above the bottom of the guide block 201, so that the corner protectors 6 can fall from the spiral 202 onto the guide block 201; the two ends of the side wall of the trough 208 near the center of the hopper 203 are provided with drop ports 207, which allow the corner protectors 6 that do not meet the requirements to fall back onto the hopper 203 for rearrangement.

[0032] As a preferred embodiment, a baffle 209 is provided at the end of the feed trough 208 and the guide block 201. The baffle 209 has a through hole that matches the corner protector 6. An elastic limiting plate 206 is provided on the outer side of the baffle 209.

[0033] As a preferred method, such as Figure 7-8 As shown, the linear feeder 5 includes a feeding track 501, which has an opening slot adapted to the corner protector 6. This not only facilitates the conveying of the corner protector 6 but also prevents it from popping out or flipping, ensuring the stability of the equipment operation. A vibrator 504 is installed at the bottom of the feeding track 501, and is fixedly mounted on a mounting frame 505. The mounting frame 505 is bolted to the mounting platform 3. The vibrator 504 vibrates the corner protector 6 located in the opening slot to vibrate. The feeding track 501 is equipped with a corner protection positioning groove 502 at its end. An electric push rod 503 is located behind the corner protection positioning groove 502. The output end of the electric push rod 503 is connected to the corner protection positioning groove 502. The corner protection positioning groove 502 is slidably mounted on the mounting frame 505, and the electric push rod 503 is fixedly mounted on the mounting frame 505. When the corner protection enters the corner protection positioning groove 502, the electric push rod 503 can push the corner protection positioning groove 502 to move, so that the mechanical gripper 4 can grasp it.

[0034] As a preferred method, such as Figure 5-6 As shown, the mechanical gripper 4 includes a mounting base 402, which is L-shaped and its bottom end is connected to the mounting platform 3 via a frame.
