Description

Technical Field

[0001] This utility model relates to the field of defective product rejection technology, specifically a device for rejecting products fixed on a cylindrical eaves fixture. Background Technology

[0002] The term "cylindrical product with an eave" mainly refers to a lightweight cylindrical jig with an eave used to fix the shape of caps, bottles, etc., and is more closely related to a cylindrical object inserted into a production line to fix the product.

[0003] However, during the production and painting of cap-shaped products, the products are fixedly clamped onto fixtures, which are placed on the assembly line station. During production, due to differences in processes and other reasons, some defective products will appear on the production line. When removing these defective products, manual removal is required, which increases labor costs. Moreover, it is unsafe for workers to be located next to the production line, and it is impossible to efficiently remove the cylindrical fixtures and cap-shaped and bottle-shaped products that are inserted into the cylindrical station. Utility Model Content

[0004] The purpose of this invention is to provide a device for removing defective products fixed on a columnar eaves fixture, in order to solve the problem mentioned in the background art that manual removal is required when removing these defective products.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for removing products fixed on a columnar eaves fixture, comprising:

[0006] The frame has a photoelectric switch on its exterior and a material feeding groove on its back. Two electric cylinders are symmetrically arranged inside the frame. The output rod of each electric cylinder is connected to a pneumatic valve shaft. A first air nozzle is located above the end of the outer wall of the output rod of the electric cylinder away from the pneumatic valve shaft. A second air nozzle is located at the other end of the pipe below the first air nozzle. A pneumatic valve body is located at the input end of the pipe below the first air nozzle.

[0007] Preferably, the ray direction of the photoelectric switch is perpendicular to the plane of symmetry of the two electric cylinders.

[0008] Preferably, the material feeding groove is fixedly connected to the frame, and the electric cylinder is fixedly connected to the frame.

[0009] Preferably, the pneumatic valve shaft is fixedly connected to the output rod of the electric cylinder, and the second air nozzle is located on the outside of the frame.

[0010] Preferably, the first air nozzle is located on the horizontal plate on the outer wall of the electric cylinder output rod, and the horizontal plate is fixedly connected to the electric cylinder output rod.

[0011] Preferably, the pneumatic valve body is fixedly connected to the support legs of the frame.

[0012] Preferably, the output end of the pneumatic valve body is fixedly connected to the input end of the pipe below the first air nozzle.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When the defective product rejection device of this utility model is in use, the defective product follows the production line through the center line of the frame, triggering a photoelectric switch. At this time, the electric cylinder and the pneumatic valve body act simultaneously. The pneumatic valve shaft lifts instantly, pulling the defective product off the production line. Simultaneously, compressed air is sprayed out from three nozzles (two first nozzles and two second nozzles) as the solenoid valve opens, blowing the defective product diagonally upwards. It falls onto the cotton cushioning cloth inside the frame and is finally collected from the material discharge trough. There is no need for workers to stand by the production line to reject the defective product. Each time, the defective product is accurately rejected without affecting other products. The response speed is fast, reducing labor intensity, improving production efficiency, and ensuring product quality. Attached image description:

[0021] 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.

[0022] Please see Figure 1-5One embodiment of this utility model is a device for removing products fixed on a columnar eaves fixture. The photoelectric switch 02, electric cylinder 04 and pneumatic valve body 08 used in this application are all products that can be purchased directly on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here.

[0023] The system includes: a frame 01, with a photoelectric switch 02 installed on its exterior; a feeding trough 03 on the back of the frame 01, where rejected defective products fall onto a cotton cushioning cloth inside the frame 01 and are collected from the feeding trough 03; and two symmetrically arranged electric cylinders 04 inside the frame 01, which provide power. When the electric cylinders 04 are activated, the pneumatic valve shaft 05 instantly lifts, pulling the defective products off the production line. The output rod of the electric cylinder 04 is connected to the pneumatic valve shaft 05, and the specific stroke of the pneumatic valve shaft 05 is set according to the height of the fixture, with the stroke determined by feedback signals from a magnetic switch. A first air nozzle 06 is provided above the end of the outer wall of the output rod of the electric cylinder 04 away from the pneumatic valve shaft 05. A second air nozzle 07 is provided at the other end of the pipe below the first air nozzle 06. The second air nozzle 07 cooperates with the two first air nozzles 06 to spray gas, blowing the defective products obliquely upwards and onto the cotton cushioning cloth inside the frame 01. Finally, the products fall and are collected from the material discharge trough 03. A pneumatic valve body 08 is provided at the input end of the pipe below the first air nozzle 06. The pneumatic valve 08 is controlled by an electrical signal to open and close the valve, thereby controlling the compressed air to be sprayed out through the second air nozzle 07 and the two first air nozzles 06, for a total of three air nozzles.

[0024] Furthermore, the ray direction of photoelectric switch 02 is perpendicular to the plane of symmetry of the two electric cylinders 04. When defective products follow the production line through the center line of frame 01, they will trigger photoelectric switch 02.

[0025] Furthermore, the feeding trough 03 is fixedly connected to the frame 01 to ensure the stability of the feeding trough 03. The rejected defective products fall onto the cotton cushioning cloth inside the frame 01 and are finally collected from the feeding trough 03. The electric cylinder 04 is fixedly connected to the frame 01 to ensure the stability of the electric cylinder 04. The electric cylinder 04 provides power. After the electric cylinder 04 is started, the pneumatic valve shaft 05 is lifted instantly, pulling the defective products off the production line.

[0026] Furthermore, the pneumatic valve shaft 05 is fixedly connected to the output rod of the electric cylinder 04. The electric cylinder 04 provides power. After the electric cylinder 04 is started, the pneumatic valve shaft 05 is lifted instantly, pulling the defective product out of the production line. The second air nozzle 07 is located on the outside of the frame 01. The second air nozzle 07 cooperates with the two first air nozzles 06 to spray gas, blowing the defective product obliquely upward and onto the cotton cushioning cloth inside the frame 01. Finally, it falls and is collected from the material discharge trough 03.

[0027] Furthermore, the first air nozzle 06 is located on the horizontal plate on the outer wall of the output rod of the electric cylinder 04, and the horizontal plate is fixedly connected to the output rod of the electric cylinder 04. The first air nozzle 06 sprays gas through the gas supplied by the lower pipe, and cooperates with the second air nozzle 07 to blow the defective products obliquely upwards, and they fall into the frame 01 covered with cotton cushioning cloth, and finally fall and be collected from the material discharge groove 03.

[0028] Furthermore, the pneumatic valve body 08 is fixedly connected to the support legs of the frame 01 to ensure the stability of the pneumatic valve body 08. The pneumatic valve 08 is controlled by an electrical signal to open and close, thereby controlling the compressed air to be ejected through the second air nozzle 07 and the two first air nozzles 06, for a total of three air nozzles.

[0029] Furthermore, the output end of the pneumatic valve body 08 is fixedly connected to the input end of the pipeline below the first air nozzle 06. The pneumatic valve 08 is controlled by an electrical signal to open and close, thereby controlling the compressed air to be ejected through the second air nozzle 07 and the two first air nozzles 06, for a total of three air nozzles.

[0030] Working principle: During use, defective products follow the production line through the center line of frame 01, triggering photoelectric switch 02. At this time, electric cylinder 04 and pneumatic valve body 08 act simultaneously, and pneumatic valve shaft 05 instantly lifts, pulling the defective product off the production line. Simultaneously, compressed air, along with the opening of the solenoid valve, is ejected from three nozzles (two first air nozzles 06 and two second air nozzles 07), blowing the defective product diagonally upwards. It then falls onto the cotton cushioning cloth inside frame 01 and is finally collected from the material discharge trough 03. The above is the complete working principle of this utility model.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
