Description

Technical Field

[0001] The utility model relates to the technical field of bag-packing suction devices, in particular to a generator-type bag-packing suction device. Background Art

[0002] In the prior art, the handling and stacking of bagged materials (such as rice, flour, sugar, etc.) is an important process. Traditional handling methods mainly rely on manual or mechanical grippers, which are inefficient and easily cause damage or contamination of materials.

[0003] In recent years, with the development of automation technology, vacuum suction cup technology has been increasingly used in the handling of bagged materials. Vacuum suction cups generate negative pressure to absorb bagged materials, achieving automated handling, significantly improving production efficiency, reducing labor costs, and improving handling safety. However, most current vacuum suction cup handling systems use a design that separates the vacuum pump and suction cup. The vacuum pump is used to generate negative pressure, and the suction cup is used to absorb the material. The negative pressure is transmitted between the two through an air pipe. This traditional structure has some inherent drawbacks:

[0004] First, aging, damage, or poor connections in the air pipe can lead to vacuum leaks, preventing the suction cup from effectively sucking material, or even causing the material to fall, leading to safety accidents. Furthermore, leaks increase energy consumption and reduce the overall efficiency of the system.

[0005] Secondly, it takes a certain amount of time for the vacuum pump to generate negative pressure and for the suction cup to absorb the material. The existence of the air pipe will prolong this time, especially in situations where materials need to be absorbed and released quickly, such as high-speed assembly line operations. This delay will significantly affect production efficiency. Utility Model Content

[0006] In order to solve the above problems, the utility model provides a generator-type bag suction device with fast response, reliable adsorption and convenient operation.

[0007] In order to achieve the above-mentioned purpose, the generator-type bag suction cup designed in the present invention includes a suction cup body and a vacuum generator. A mounting plane is provided on the back of the suction cup body. At least four studs are provided on the mounting plane. The studs are arranged in a rectangular shape and define an installation space for accommodating the vacuum generator. The vacuum generator is fixedly installed on the mounting plane and is located in the installation space, and the vacuum end of the vacuum generator is connected to the suction cup body through an air pipe so that the gas in the suction cup body is sucked into the vacuum generator to generate negative pressure. The front of the suction cup body is open, and a sealing patch is provided around the edge of the opening.

[0008] Preferably, the contact surface of the sealing patch is a flat surface parallel to the mounting plane.

[0009] Preferably, a positioning groove adapted to the sealing patch is formed on the open edge of the suction device body, and the sealing patch is fixedly installed in the positioning groove.

[0010] Preferably, the sealing patch is made of rubber sponge.

[0011] Preferably, the gripper body is an elliptical disc structure, and each of the studs is a single-head hexagonal stud threadedly fastened on the mounting plane.

[0012] Preferably, a suction port is provided on the mounting plane, and the vacuum end of the vacuum generator is connected to the suction port through an air pipe.

[0013] Preferably, a digital pressure switch is further included, and a detection port is also provided on the installation plane. The pressure port of the digital pressure switch is directly threadedly connected to the detection port, or is connected to the detection port through an L-shaped adapter.

[0014] Preferably, the vacuum generator includes a generator body, and an air inlet and an exhaust port arranged on the generator body, the exhaust port is connected to a silencer, and the generator body is provided with a countersunk screw hole extending along the thickness direction of the generator body and passing through the generator body.

[0015] Preferably, a plurality of positioning holes are provided on a side of the generator body facing the gripper body, and a positioning column corresponding to each of the positioning holes is provided on the mounting plane.

[0016] The generator-type bag gripper designed in this utility model integrates the vacuum generator with the gripper body in a patch-type manner, forming a compact, one-piece structure. This integrated design greatly shortens the vacuum path, significantly improving the response speed from vacuum generation to vacuum action on the suction cup. This means that the gripper can absorb and release materials more quickly, significantly improving handling efficiency. This efficiency improvement is particularly prominent in high-speed automated production lines that require frequent material absorption and release. In addition, the rectangular arrangement of the studs defines the installation space for the vacuum generator. While facilitating the connection of external equipment, it also provides maximum protection for the vacuum generator, preventing unexpected collision damage and making it easier to operate and maintain.

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0023] like Figures 1 to 4 As shown, the generator-type bag-packing gripper described in this embodiment is mainly used for vacuum handling of bag-packing materials (such as rice, flour, sugar, etc.), and mainly includes a gripper body 10 and a vacuum generator 20. A mounting plane 11 is provided on the back of the gripper body 10. At least four studs 30 are provided on the mounting plane 11. The studs 30 are arranged in a rectangular shape and define an installation space 40 for accommodating the vacuum generator 20; the vacuum generator 20 is fixedly installed on the mounting plane 11 and is located in the installation space 40, and the vacuum end 21 of the vacuum generator 20 is connected to the gripper body 10 through an air pipe, so that the gas in the gripper body 10 is sucked into the vacuum generator 20 to generate negative pressure; the front of the gripper body 10 is open, and a sealing patch 50 is provided around the edge of the opening.

[0024] During operation, the vacuum generator 20 starts and generates negative pressure. The gas in the suction cup body 10 is sucked into the vacuum generator 20 through the air pipe, thereby forming a negative pressure area at the open part of the suction cup body 10. A sealing patch 50 is provided around the edge of the open part of the suction cup body 10. The sealing patch 50 fits tightly with the surface of the bagged material, enhancing the adsorption effect and preventing air leakage, thereby ensuring reliable adsorption force.

[0025] When bagged materials need to be transported, the operator or the automated system aligns the opening of the gripper 100 with the surface of the material to be transported and starts the vacuum generator 20. The negative pressure generated by the gripper 100 is quickly transmitted to the interior of the gripper body 10 through the connecting air pipe and acts on the sealing patch 50, so that the gripper 100 is firmly adsorbed on the bagged materials. After the transport is completed, the vacuum generator 20 is stopped and the gripper 100 can quickly release the materials.

[0026] In a specific implementation, at least four studs 30 on the mounting surface 11 on the back of the gripper body 10 can be used to secure the gripper 100 to a robotic arm, conveyor belt, or other moving parts on a production line to achieve automated handling. In this embodiment, the number and arrangement of the studs 30 can be adjusted according to actual needs. For example, four or more studs can be selected based on the size, weight, and force conditions of the gripper and arranged in a rectangular, square, or other geometric shape. The installation space 40 formed by the rectangular arrangement of multiple studs 30 provides a certain degree of protection for the vacuum generator 20 therein without the need for an additional protective housing, protecting it from unexpected external impacts. At the same time, because the vacuum end 21 of the vacuum generator 20 is connected to the gripper body 10 via a relatively short air tube, the response speed from vacuum generation to vacuum action on the gripper body 10 is greatly improved. This means that the gripper body 10 can absorb and release materials more quickly, thereby significantly improving handling efficiency. This efficiency improvement is particularly prominent in high-speed automated production lines that require frequent material absorption and release. In addition, shorter air tube connections also help reduce the possibility of vacuum leakage, further improving the reliability and stability of the gripper.

[0027] In some embodiments, as Figure 2 、 Figure 3 As shown, the contact surface 51 of the sealing patch 50 is a flat surface parallel to the mounting plane 11. This design allows the sealing patch 50 to fully contact the surfaces of bagged materials of various shapes. Even if the bagged material surface has slight wrinkles or unevenness, the flat contact surface 51 ensures sufficient contact area, thereby providing reliable adsorption. In this embodiment, the sealing patch 50 is made of rubber sponge.

[0028] In some embodiments, as Figure 4 As shown, the open edge of the suction device body 10 is provided with a positioning groove 12 adapted to the sealing patch 50, and the sealing patch 50 is fixedly installed in the positioning groove 12. Specifically, the shape and size of the positioning groove 12 match the edge shape and size of the sealing patch 50, ensuring that the sealing patch 50 can be firmly fixed to the suction device body 10. This can prevent the sealing patch 50 from shifting or falling off during transportation, thereby ensuring the reliability of adsorption. In addition, the design of the positioning groove 12 also simplifies the installation process of the sealing patch 50, eliminating the need for additional adhesives or fixings, reducing installation costs and maintenance difficulties.

[0029] In some embodiments, as Figure 1 、 Figure 2As shown, the gripper body 10 is an elliptical disc structure, and each stud 30 is a single-headed hexagonal stud 30 that is threadedly fastened to the mounting surface 11. Specifically, the long axis of the gripper body 10, which has an elliptical disc structure, aligns with the long side of the material to be handled, maximizing coverage of the material surface and providing stronger suction. The single-headed hexagonal stud 30 is a standardized fastener that is threadedly fastened to the mounting surface 11, allowing for manual disassembly and assembly when necessary without the need for special tools, making it convenient and quick.

[0030] In some embodiments, as Figure 1 、 Figure 3 As shown, a suction port 13 is formed on the mounting surface 11, and a vacuum end 21 of the vacuum generator 20 is connected to the suction port 13 via an air pipe. Thus, different models of vacuum generators 20 can be connected to the suction port 13 via an air pipe, making them compatible with different models of vacuum generators. This allows users to select vacuum generators of different specifications and brands according to actual needs without having to make any changes to the gripper body 10.

[0031] In another embodiment, the vacuum generator 20 can be arranged on a side of the vacuum generator 20 relative to the mounting plane, so that the vacuum end 21 is directly connected to the suction port 13 on the mounting plane 11. This design completely eliminates the need for connecting the air pipe, thereby avoiding possible leakage at the air pipe connection, further improving the reliability and adsorption efficiency of the system.

[0032] In some embodiments, as Figure 1 、 Figure 2 、 Figure 3 As shown, a digital pressure switch 60 is also included, and a detection port 14 is also provided on the installation plane 11. The pressure port of the digital pressure switch 60 is directly threadedly connected to the detection port 14, or is connected to the detection port 14 through an L-shaped adapter 61. Specifically, the detection port 14 is provided on the installation plane 11 and is connected to the internal space of the suction device body 10. The digital pressure switch 60 can display the real-time pressure value and can set the alarm threshold. In specific implementation, the digital pressure switch 60 can be configured to issue an alarm when the pressure value is lower than the preset threshold, reminding the operator or the control system to take corresponding measures. In addition, the use of the L-shaped adapter 61 can flexibly adjust the installation angle of the digital pressure switch 60 according to the requirements of the actual installation space, thereby improving the convenience of installation.

[0033] In some embodiments, as Figure 1 、 Figure 4As shown, the vacuum generator 20 includes a generator body 22, an air inlet 23 and an exhaust port 24 provided on the generator body 22. The exhaust port 24 is connected to a muffler 25. The generator body 22 is provided with a countersunk screw hole 26 extending along the thickness direction of the generator body 22 and penetrating the generator body 22. The design of the countersunk screw hole 26 facilitates the installation and fixation of the vacuum generator 20. The vacuum generator 20 can be firmly fixed to the suction device body 10 using a countersunk screw to prevent it from loosening or shifting during operation.

[0034] In some embodiments, as Figure 4 As shown, the generator body 22 has a plurality of positioning holes 27 formed on the side facing the gripper body 10, and the mounting surface 11 is provided with positioning posts 15 corresponding to each of the positioning holes 27. Specifically, the number and position of the positioning holes 27 and the positioning posts 15 correspond to each other, ensuring that the vacuum generator 20 can be installed in a single, correct position, thus preventing misalignment and improving installation efficiency.

[0035] The generator-type bag gripper provided in this embodiment integrates the vacuum generator with the gripper body in a patch-type manner, forming a compact, one-piece structure. This integrated design significantly shortens the vacuum path, significantly improving the response speed from vacuum generation to vacuum action on the suction cup. This means the gripper can absorb and release materials more quickly, significantly improving handling efficiency. This efficiency improvement is particularly prominent in high-speed automated production lines that require frequent material absorption and release. In addition, the rectangular arrangement of the studs defines the installation space for the vacuum generator. While facilitating the connection of external devices, it also provides maximum protection for the vacuum generator, preventing unexpected collision damage and making it easier to operate and maintain.
