Description

Technical Field

[0001] This invention belongs to the field of glass bottle conveying technology, and specifically relates to a glass bottle conveyor and a glass bottle protection method. Background Technology

[0002] In the glass bottle manufacturing process, during the coating and spraying stage, a chain conveyor belt is used to transport the glass bottles inverted to the spraying station for spraying. However, during the glass bottle transport process, the glass bottles may break when they resonate with the mechanical structure. Therefore, those skilled in the art need a glass bottle conveyor with stronger protective capabilities.

[0003] The existing patent application number 201810346037.8 discloses a vertical and stable glass bottle conveying device that is easy to pick up and put down, including a conveyor belt, a bottle placement attraction mechanism, a clamping mechanism, a bottle retrieval attraction mechanism, and a slide rail. The conveyor belt is evenly provided with a plurality of clamping mechanisms, and the left and right ends of the conveyor belt are respectively provided with a bottle placement attraction mechanism and a bottle retrieval attraction mechanism. The bottom of the bottle placement attraction mechanism and the bottle retrieval attraction mechanism are provided with a slide rail for adjusting the bottle placement attraction mechanism and the bottle retrieval attraction mechanism back and forth.

[0004] The existing technology has the following drawbacks:

[0005] The glass bottle is clamped by a clamping mechanism and placed in the groove on the top of the fixing plate. The clamping rod is in a vertical position by the action of the torsion spring. The glass bottle can be clamped by the clamping plate, and the rubber layer on the inner surface of the clamping plate can protect the glass bottle. This external clamping and positioning method will affect the coating on the outside of the glass bottle. Summary of the Invention

[0006] This invention provides a glass bottle conveyor and a glass bottle protection method, which can solve the technical problem that the external clamping and positioning methods in the prior art can affect the coating on the outside of the glass bottle.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0008] This application provides a glass bottle conveyor, including a power system and a chain conveyor belt, and further comprising:

[0009] A central tube is inserted into the bottle cavity, and the central tube has an air passage.

[0010] A positioning airbag is connected to the outer periphery of the central tube on the side facing the bottom of the bottle, and the positioning airbag is in communication with the airway.

[0011] A cylinder is connected to the end of the central tube opposite to the bottle body. The cylinder is connected to the air passage and is detachably connected to the chain conveyor belt.

[0012] The mandrel is slidably connected inside the central tube. One end of the mandrel abuts against the bottom of the bottle body, and the end of the mandrel away from the bottle body is connected to the piston inside the cylinder.

[0013] When the bottle body presses down on the mandrel, the mandrel compresses the piston downward, causing the cylinder to inflate the positioning airbag, and the inflated positioning airbag abuts against the inside of the bottle body.

[0014] The above technical solution uses gravity to inflate the positioning airbag, and the positioning airbag and mandrel provide internal positioning for the glass bottle simultaneously, which enhances the protection of the glass bottle without affecting the spraying process.

[0015] In this invention, the glass bottle conveyor further includes:

[0016] A sealing airbag is connected to the outer periphery of the central tube on the side facing the bottle opening, and the sealing airbag is in communication with the airway;

[0017] The aforementioned closed airbag is connected to the positioning airbag. When the closed airbag is inflated and compressed, the positioning airbag undergoes elastic deformation.

[0018] By employing the above technical solutions, a sealed airbag is used to increase the contact positioning points, while the sealed bottle opening prevents atomized paint from entering the bottle body, thus improving the yield rate of the glass bottle spraying process.

[0019] In this invention, the glass bottle conveyor further includes:

[0020] A buffer rubber head is connected to the end of the mandrel facing the bottom of the bottle, and the buffer rubber head has friction when it comes into contact with the bottom of the bottle.

[0021] The above technical solution, which uses a buffer rubber head, avoids hard contact between the mandrel and the bottom of the bottle, further improving the protection capability for glass bottle transportation.

[0022] In this invention, the cylinder has a negative pressure chamber and a positive pressure chamber. When the piston is pressed down, the negative pressure chamber becomes larger and the positive pressure chamber is compressed, and the gas in the positive pressure chamber enters the air passage.

[0023] By employing the above technical solution and setting up a negative pressure chamber inside the cylinder, the springback capability of the mandrel can be improved, and the operation steps for placing glass bottles can be simplified.

[0024] In this invention, the side wall of the positive pressure chamber is connected to an air valve.

[0025] The above technical solution uses a gas valve to adjust the pressure of the positive pressure chamber, thereby adapting to glass bottles with different wall thicknesses and structures, and improving the adaptability of the equipment.

[0026] In this invention, the glass bottle conveyor further includes:

[0027] An elastic flange is integrally formed with the positioning airbag, and the elastic flange is snapped into the air passage.

[0028] The above technical solution, which uses a flexible flange to assemble and position the airbag, makes it easy to replace airbags of different sizes, thereby adapting to glass bottles with different inner diameters and further improving the adaptability of the equipment.

[0029] This application also provides a method for protecting glass bottles, which uses the aforementioned glass bottle conveyor and further includes the following steps:

[0030] Step S10: Insert the batch sample of glass bottle into the central tube, and adjust the pressure of the positive pressure chamber through the air valve until the glass bottle will not resonate and break due to the vibration of the chain conveyor belt.

[0031] Step S20: Set all cylinders on the chain conveyor belt to the air pressure values ​​obtained in step S10;

[0032] Step S30: Insert the spray-coated glass bottles one by one into the central tube. When the positioning airbag expands as the bottle presses down on the mandrel, continue to press down on the bottle until the expanded sealing airbag is inserted into the bottle opening.

[0033] Step S40: Slightly press down on the bottle until it rebounds upwards after losing external pressure.

[0034] The above technical solution uses an experimental approach to obtain the optimal air pressure. Then, by utilizing the elastic deformation of the airbag and the damping effect of the cylinder, the vibration filtering effect of the glass bottle is improved in a synergistic manner, further enhancing the protection capability of the glass bottle.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] Example:

[0048] Please refer to Figures 1 to 6 , Figures 1 to 6 The image shown is an embodiment of this application.

[0049] This embodiment provides a glass bottle conveyor, including a power system and a chain conveyor belt. It should be noted that this conveyor is a commonly used equipment for glass bottle spraying, such as... Figure 1 As shown, the rotating base 3 is mounted on a chain conveyor belt. Then, at the spraying station, a fixed chain causes the gears on the rotating base 3 to rotate the entire bottle 4 through the interaction of the chain. In existing technologies, tooling is generally used to directly and loosely insert the glass bottle onto the rotating base 3. However, in this embodiment... Figure 2 and Figure 3 As shown, it also includes features different from existing technologies:

[0050] The central tube 103 is inserted into the four cavities of the bottle body and has an air passage.

[0051] The positioning airbag 101 is an annular elastic airbag connected to the outer periphery of the central tube 103 facing the bottom of the bottle body 4. The positioning airbag 101 is connected to the air passage through two channels. It should be noted that the positioning airbag 101 has a certain degree of elasticity and friction. However, after inflation, the bottle body 4 can still move up and down slightly relative to the central tube 103 when the positioning annular elastic airbag is compressed and deformed or rolled. The up and down rolling of the positioning airbag 101 is limited by the air passage, but it will not cause the positioning airbag 101 to detach from the central tube 103. Simply put, the positioning airbag 101 only acts on circumferential positioning and vibration filtering and does not participate in axial limiting.

[0052] like Figure 5 As shown, cylinder 201 is threadedly connected to the end of central tube 103 away from bottle body 4. Cylinder 201 is connected to air passage. Cylinder 201 is connected to rotating seat 3 through adapter 203. Then, it is detachably connected to chain conveyor belt through rotating seat 3.

[0053] like Figure 3 As shown, the mandrel 104 is slidably connected to the through hole in the middle of the central tube 103. One end of the mandrel 104 abuts against the bottom of the inner side of the bottle body 4, and the end of the mandrel 104 away from the bottle body 4 is connected to the piston in the cylinder 201.

[0054] When the bottle body 4 presses down the core rod 104, the core rod 104 compresses the piston downward, causing the cylinder 201 to inflate the positioning airbag 101. After the positioning airbag 101 is inflated, it comes into contact with the inside of the bottle body 4.

[0055] It should be emphasized that, although the patent "An Automatic Bottle Loading Device for Hot Ends of Glass Bottles and Jars" with application number 202422811172.9 also uses an airbag for positioning inside the bottle, the elastic airbag used there is fixedly connected to the bottom center of the rotating block. It is connected to the inflation pipe on the top of the fixed block through the inflation hole set in the center of the rotating block. The inflation pipe can be connected to an external air pump to inflate the elastic airbag. Therefore, if it is simply applied to the conveyor with a chain conveyor belt as in this embodiment, it is impossible to do so without creative work to set up an inflation pipe that flows with the conveyor belt. This embodiment is a collaborative technical solution of setting the airbag inside and using the weight of the bottle 4 for inflation and deflation, which is more in line with the technical optimization of traditional chain conveyor belt conveyors.

[0056] The above technical solution uses gravity to inflate the positioning airbag 101, and the positioning airbag 101 and the mandrel 104 provide internal positioning for the glass bottle simultaneously, which enhances the protection of the glass bottle without affecting the spraying process.

[0057] In a preferred embodiment, the glass bottle conveyor described above further includes:

[0058] like Figure 3 As shown, the sealing airbag 102 is connected to the outer periphery of the central tube 103 on the side facing the bottle opening 4. The sealing airbag 102 is connected to the airway. Except for its size, the sealing airbag 102 is basically the same as the positioning airbag 101.

[0059] The aforementioned closed airbag 102 is connected to the positioning airbag 101. When the closed airbag 102 is inflated and squeezed, the positioning airbag 101 undergoes elastic deformation. In use, the two airbags enter the bottle body 4 through mutual air transfer between the two airbags.

[0060] It should be noted that attention should be paid to the friction between the two airbags and the inside of the bottle 4. The modified rubber is used to prevent the friction from causing the two airbags to detach from the central tube 103 when the bottle 4 is removed. This application does not protect the specific composition of the modified rubber, so it will not be further explained or specifically limited here. Those skilled in the art can purchase it through custom or public channels and screen suitable modified rubber as the material of the airbag through a limited number of tests.

[0061] By using the above technical solution, the use of a sealed airbag 102 increases the contact positioning points, while sealing the bottle mouth to prevent atomized paint from entering the bottle body 4, thereby improving the yield rate of the glass bottle spraying process.

[0062] In a preferred embodiment, the glass bottle conveyor described above further includes:

[0063] like Figure 4As shown, the buffer head 105 is connected to the end of the core rod 104 facing the bottom of the bottle, and the buffer head 105 has friction when it comes into contact with the bottom of the bottle.

[0064] It should be noted that the contact surface between the buffer rubber head 105 and the bottom of the bottle needs to be arc-shaped to minimize the contact area. This is because the main function of the buffer rubber head 105 is to provide axial positioning, but it is also necessary to avoid excessive friction with the bottom of the bottle, which could cause the contact point to shift off-center from the bottom of the bottle when the positioning airbag 101 is not inflated, ultimately resulting in uneven force distribution inside the glass bottle.

[0065] By employing the above technical solution and using the buffer rubber head 105, the core rod 104 is prevented from making hard contact with the bottom of the bottle, thus further improving the protection capability for glass bottle transportation.

[0066] In a preferred embodiment, the cylinder 201 has a negative pressure chamber 2011 and a positive pressure chamber 2012. When the piston is pressed down, the negative pressure chamber 2011 becomes larger and the positive pressure chamber 2012 is compressed, and the gas in the positive pressure chamber 2012 enters the air passage.

[0067] In use, the pressure difference between the negative pressure chamber 2011 and the positive pressure chamber 2012 counteracts the weight of the bottle body 4. If necessary, [further details are needed]. Figure 4 As shown, a reset spring 106 can also be connected between the buffer rubber head 105 and the central tube 103. That is, the core rod 104 is quickly reset and the gas in the air bag is extracted when the bottle body 4 is taken out upward by the reset spring 106 and the pressure difference, thereby reducing the friction of the positioning air bag 101 on the bottle mouth.

[0068] By adopting the above technical solution and setting the negative pressure chamber 2011 inside the cylinder 201, the rebound ability of the mandrel 104 can be improved and the operation steps of placing the glass bottle can be simplified.

[0069] like Figure 5 As shown, in a preferred embodiment, the side wall of the positive pressure chamber 2012 is connected to a gas valve 2013.

[0070] The 2013 air valve uses a traditional air filling device, such as a tire valve, to perform inflation and deflation operations.

[0071] It should be noted that because the positioning and vibration filtering method is based on internal pressure contact, and the physical properties of the glass bottle itself determine that it has strong pressure resistance but weak tensile strength, the air pressure, such as in step S10, needs to be determined in advance through sample testing to determine the safe air pressure and the optimal air pressure.

[0072] The above technical solution uses a gas valve 2013 to adjust the pressure of the positive pressure chamber 2012, thereby adapting to glass bottles with different wall thicknesses and structures, and improving the adaptability of the equipment.

[0073] like Figure 6As shown, in a preferred embodiment, the glass bottle conveyor further includes:

[0074] The flexible flange 1011 is integrally formed with the positioning airbag 101, and the flexible flange 1011 is snapped into the airway.

[0075] When in use, the appropriate size airbag can be quickly replaced according to the size and diameter of different glass bottles to avoid damage to the airbag and failure to make full contact due to excessive size difference.

[0076] By using the above technical solution, the positioning airbag 101 is assembled with the elastic flange 1011, which makes it easy to replace airbags of different sizes, thereby adapting to glass bottles with different inner diameters and further improving the adaptability of the equipment.

[0077] This embodiment also provides a method for protecting glass bottles, which uses the glass bottle conveyor described above and further includes the following steps:

[0078] Step S10: Insert the batch sample of glass bottle into the central tube 103, and adjust the pressure of the positive pressure chamber 2012 through the air valve 2013 until the glass bottle will not resonate and break due to the vibration of the chain conveyor belt.

[0079] Step S20: Set all cylinders 201 on the chain conveyor belt to the air pressure value obtained in step S10;

[0080] Step S30: Insert the spray-coated glass bottles one by one into the central tube 103. When the positioning airbag 101 expands as the bottle body 4 presses down on the core rod 104 by its own weight, continue to press down on the bottle body 4 until the expanded sealing airbag 102 is inserted into the bottle mouth.

[0081] Step S40: Slightly press down on bottle 4 until bottle 4 can rebound upwards after losing external pressure.

[0082] The above technical solution uses an experimental approach to obtain the optimal air pressure. Then, by utilizing the elastic deformation of the airbag and the damping effect of the cylinder 201, the vibration filtering effect of the glass bottle is improved in a coordinated manner, thereby further enhancing the protection capability of the glass bottle.

[0083] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
