Description

Technical Field

[0001] The invention relates to the technical field of mechanical assembly, and in particular to an open-type vibration plate feeding device with external circulation. Background Art

[0002] In modern automated production lines, vibrating plate feeding systems are widely used for the automatic distribution and arrangement of various bulk products. These systems mainly rely on vibration devices to arrange irregular bulk products and distribute the products to designated locations in order as needed. In the prior art, although there are certain automated feeding systems that can achieve product arrangement, they can usually only distribute materials at a single location and have the following problems: Single material distribution position, low efficiency: Traditional vibrating plate feeding system can only achieve the distribution of a single material distribution position. In the production line that requires multiple material distribution positions, it cannot meet the efficient production requirements. Multiple material distribution positions need to be completed by multiple separate devices or manual intervention, which is inefficient and prone to errors.

[0003] Precision issues in the distribution process: In the prior art, due to the inaccuracy of the mechanical structure and control system during the distribution process, the product may not fall accurately into the specified position, thereby affecting production efficiency and product quality.

[0004] The return system is imperfect and resources are wasted: The current return mechanism is usually simple, which may lead to waste of excess products or poor recycling process, and it is impossible to effectively recover and put back into use excess or misplaced products to the greatest extent.

[0005] Requires complex manual intervention: In some existing systems, due to the lack of accuracy and intelligence in product allocation, manual adjustment and intervention are still required, which reduces the degree of automation. Summary of the invention

[0006] The purpose of the present invention is to provide an open-type vibration plate feeding device with external circulation, so as to solve the problems of inaccurate material distribution, low efficiency and poor material return in the prior art.

[0007] The present invention is implemented by adopting the following technical scheme: an open-type vibration plate feeding device with external circulation, characterized in that it includes a material selection vibration plate for receiving bulk products and arranging them by vibration; a one-to-two straight vibration feeding plate, which is arranged below the material selection vibration plate and is used to distribute the arranged products to multiple material picking positions; a material guide trough, which is arranged on the one-to-two straight vibration feeding plate and is used to guide the products coming out of the material selection vibration plate; multiple material picking positions are arranged on the material guide trough, and each material picking position is provided with a lifting cylinder and a drop hole; a lifting cylinder, which is arranged at each material picking position, is used to drive a push rod to perform a lifting operation; a push rod, which is installed on the lifting cylinder and has a contoured structure on the top; a detection optical fiber, which is used to detect the state of the material picking position and feed back a signal to the control system.

[0008] Furthermore, the one-to-two direct-vibration material transfer plate realizes vibration conveying through a direct-vibration device, pushing the product to move forward along the material guide trough.

[0009] Furthermore, the contoured structure of the ejector rod is in close contact with the lower surface of the product. When the product passes through, the upper surface of the product is flush with the bottom surface of the guide trough, ensuring that subsequent products pass through smoothly.

[0010] Furthermore, the return material collecting bin is arranged at the end of the one-to-two straight vibration feeding plate, for collecting excess or mis-added products, and is connected to the material selection vibration plate through a return material pipeline.

[0011] Furthermore, a conveying type vacuum generator is provided on the return material pipeline for conveying the recovered product back to the material selection vibration plate.

[0012] Furthermore, the detection optical fiber is installed inside the push rod to detect whether a product has fallen onto the push rod and to control the action of the lifting cylinder according to a feedback signal.

[0013] Furthermore, the material selection vibration plate generates vibration through a vibrator, so that the products are arranged in an orderly manner and enter multiple material taking positions on the one-to-two direct vibration material transfer plate through a material guide trough.

[0014] The external circulation open vibration plate feeding device described in the present invention has the following beneficial effects: The present invention can achieve product distribution at multiple designated positions at one time through the design of multiple material collection positions, greatly improving the efficiency of material distribution. By accurately controlling the lifting cylinder and the contoured ejector rod at each material collection position, the product can be quickly and accurately distributed to the predetermined position, avoiding manual intervention, reducing distribution errors and production line downtime. Through the contoured structure of the ejector rod and the cylinder control technology, it can be ensured that each product falls accurately into the designated position, and the product surface is flush with the bottom surface of the guide trough, ensuring the smooth passage of subsequent products. This design significantly improves the distribution accuracy and realizes simultaneous material collection at multiple points. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1-3 As shown, an external circulation open vibration plate feeding device includes a material selection vibration plate 7, a one-to-two direct vibration feeding plate 1, a material guide trough 2, a return material receiving bin 8, a conveying type vacuum generator 5, etc. The material guide trough 2 is located on the one-to-two direct vibration feeding plate 1, and a plurality of material taking positions 3 are arranged on the material guide trough 2, and each material taking position 3 is provided with a lifting cylinder 9 and a material drop hole. The one-to-two direct vibration feeding plate 1 realizes vibration conveying through direct vibration 4.

[0020] The material selection vibration plate 7 is used to receive bulk products 12 and arrange the products in a row by means of vibration. The vibration plate is vibrated by an exciter to arrange the products in a certain direction and orderly feed them into the guide trough 2 on the one-to-two direct vibration feeding plate 1. The function of the guide trough 2 is to guide the arranged products into the designated material taking position 3.

[0021] A push rod 10 is provided on the lifting cylinder 9. The top of the push rod 10 is a contoured structure, which can be in close contact with the lower surface of the product 12, so that the product 12 can fall into the contoured structure when passing through. The upper surface of the product 12 is flush with the bottom surface of the guide trough 2, so that the subsequent product 12 can pass from the top of the product 12 that falls into the contoured structure. A detection optical fiber 11 is provided in the push rod 10.

[0022] When the blanking holes of the material taking position 3 are all filled, the detection optical fiber 11 will judge the material distribution state according to the feedback signal. Once all positions are filled, the optical fiber system will instruct the lifting cylinder 9 to perform the lifting action.

[0023] The lifting cylinder 9 will raise the push rod 10, and the excess product 12 will freely fall on the one-two straight vibration feeding plate 1 through the top of the profiling structure, and finally flow into the return material receiving bin 8. The return material receiving bin 8 is connected to the material selection vibration plate 7 through the return material pipeline 6, and a conveying vacuum generator 5 is arranged on the return material pipeline 6.

[0024] When one material taking position 3 is filled, the product 12 will continue to move along the material guide trough 2 until it reaches the next material taking position 3, and fill the remaining material taking positions 3 in sequence until all positions are occupied.

[0025] The above embodiments describe the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
