Description

Technical Field

[0001] The utility model relates to the technical field of cap conveying and sterilizing, in particular to a chain-type cap conveying device and a cap sterilizing device. Background Art

[0002] The dry sterilization process is a sterilization process that uses gasified disinfectants or radiation to sterilize packaging materials. It is a sterilization process for packaging materials with extremely low or no water content. It consumes very little water and disinfectants, is energy-efficient and highly efficient, and is therefore very popular in the market and has been widely used.

[0003] The cap is an important packaging material in aseptic filling. It has threads and anti-theft barb structures that are difficult to sterilize. Therefore, no matter what sterilization process is used, a longer sterilization time is required to ensure sterilization efficiency and ensure safe aseptic filling production. Longer sterilization time requires longer sterilization cap channels and sealing grooves to meet the requirements. Therefore, the dry sterilization cap channel of the cap is very long, which occupies a large layout space.

[0004] In order to prevent the gasified disinfectant or radiation from injuring the operator and polluting the environment, the dry sterilization process needs to sterilize the packaging material in a closed environment, and the sterilization gas or radiation needs to be separated from the external space. In addition, the dry sterilization process cannot provide power for the movement of the lid. Therefore, the existing dry lid sterilization device needs to adopt an inclined lid feeding mechanism or a star wheel to drive the lid at the front end. The inclined lid feeding mechanism has strict requirements on the slope, and the layout is more difficult. The solution of driving the lid by the star wheel at the front end requires extremely high processing accuracy of the lid groove. If the lid groove is too large or too small, it will cause the lid to be blocked, and when the lid has a small deformation, the lid will also be blocked. The chain drive lid sterilization has the advantages of compact structure and stable transportation. When the disinfection time is long, a combination of multiple chains is required, and the chain needs to be frequently adjusted and tightened to ensure reliable transmission. Since the chain guide and the lid track are fixed structures, after the chain is tightened and adjusted, the lengths of the chain, the chain guide and the lid track are not matched, which is easy to cause the lid blocking problem.

[0037] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0038] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0040] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0041] like Figure 1-Figure 6 The embodiment of the utility model provides a chain-type cover conveying device and a cover sterilizing device, the cover sterilizing device comprises a box body 100, the box body 100 is provided with a cover inlet and a cover outlet, and a sterilization chamber 101 is provided in the box body 100; the chain-type cover conveying device 1 is arranged in the box body 100 and is located in the sterilization chamber 101 between the cover inlet and the cover outlet.

[0042] like Figure 1-Figure 3The chain-type cover conveying device includes a driving mechanism 1, a chain transmission assembly 2 and a chain cover road 3. The driving mechanism 1 is configured to drive the chain transmission assembly 2 to convey the cover 200 on the chain cover road 3; the chain transmission assembly 2 includes a transmission chain 21, a driving sprocket 22, a driven sprocket 23, a paddle 24 and a chain guide 25. The transmission chain 21 is connected to the driving sprocket 22 and the driven sprocket 23 arranged at intervals. The driven sprocket 23 is combined with the driving sprocket 22, and the driven sprocket 23 is connected through a chain tensioning mechanism, so that the tightness of the transmission chain 21 can be adjusted; a plurality of paddles 24 are provided on the transmission chain 21, and the plurality of paddles 24 are arranged corresponding to the cover 200 on the chain cover road 3. When the cover 200 is transmitted, each paddle 24 can paddle a cover 200 to move on the chain cover road 3 to realize the conveyance of the cover 200. Each cover 200 is conveyed at an independent station, and no cover 200 remains in the device after production is stopped.

[0043] The chain guide 25 is arranged along the transmission chain 21 to guide the transmission chain 21. The paddle 24 is supported on the chain guide 25 to prevent the paddle 24 from sagging, skewing and other abnormal conditions. When the transmission chain 21 is adjusted to be loose, the spacing between the paddles 24 and the paddle state of the paddle 24 are affected, thereby affecting the transportation of the cover 200 to cause a cover blocking accident. In order to achieve a matching relationship between the transmission chain 21 and the chain guide 25, in the embodiment of the utility model, the chain guide 25 includes a first guide section 2511 and a second guide section 2512. The first guide section 2511 and the second guide section 2512 overlap each other along the length direction of the chain guide 25, and the length of the overlapping portion between the first guide section 2511 and the second guide section 2512 is adjustable.

[0044] like Figure 4 As shown, the overlapping parts of the first guide section 2511 and the second guide section 2512 are respectively provided with stepped assembly surfaces. In the initial state, after the first guide section 2511 and the second guide section 2512 are overlapped, the ends of the two respectively stop on the step surfaces to facilitate installation and limiting. When the transmission chain 21 is adjusted for tightness, in this embodiment, the transmission chain 21 is initially in a loose state, and the tensioning adjustment is performed through the tensioning mechanism. The conveying length of the transmission chain 21 changes, and then the spacing between the multiple paddles 24 on the transmission chain 21 changes. In order to ensure reliable support for the paddles 24, the overlapping length of the first guide section 2511 and the second guide section 2512 is adjusted, and then the length of the chain guide 25 is synchronously matched with the conveying length of the transmission chain 21, and the distance between the paddles 24 is fixed, so that the conveying of the cover 200 is more stable, and the cover blockage is effectively avoided.

[0045] The chain-type cap conveying device provided by the utility model makes the length of the chain guide rail 25 adjustable by arranging the chain guide rail 25 so that the first guide rail section 2511 and the second guide rail section 2512 overlap each other, and the overlapping length is adjustable. Therefore, after the transmission chain 21 is tightened, the length of the chain guide rail 25 can be adjusted accordingly, thereby ensuring that the paddle 24 on the transmission chain 21 is always stably supported on the chain guide rail 25, and ensuring the guiding effect of the chain guide rail 25 on the transmission chain 21, thereby solving the problem of the transmission chain 21 not matching the chain guide rail 25 after being tightened, and reducing the risk of cap blocking.

[0046] In some embodiments, the first guide rail segment 2511 or the second guide rail segment 2512 is connected to the driven sprocket 23. When the driven sprocket 23 moves to tighten the transmission chain 21, the first guide rail segment 2511 or the second guide rail segment 2512 is synchronously driven to move.

[0047] It should be noted that the driven sprocket 23 performs a rotational transmission motion, while the first guide rail segment 2511 and the second guide rail segment 2512 perform a relative movement. It can be understood that the first guide rail segment 2511 or the second guide rail segment 2512 needs to be connected to the rotating shaft of the driven sprocket 23 through a bearing; or the first guide rail segment 2511 or the second guide rail segment 2512 is connected to a tensioning mechanism, and the transmission chain 21 and the chain guide 25 are synchronously moved through the tensioning mechanism to ensure that the transmission is always matched and the movement distance is consistent, which is convenient for one-time adjustment and control.

[0048] In some embodiments, the chain guide 25 includes an outer guide 251 and an inner guide 252, and the inner guide 252 and the outer guide 251 are respectively arranged on both sides of the transmission chain 21. The inner guide 252 and the outer guide 251 are both composed of a first guide segment 2511 and a second guide segment 2512 overlapped with each other, and the paddle 24 is supported on the outer guide 251.

[0049] like Figure 2, an outer guide rail 251 and an inner guide rail 252 are respectively provided on both sides of the transmission chain 21 to guide and limit the transmission chain 21. The paddle 24 can be supported on the surface of the outer guide rail 251, and ensure the stable contact between the paddle 24 and the cover 200. The outer guide rail 251 is used to prevent the paddle 24 from sagging or tilting. The outer guide rail 251 and the inner guide rail 252 adopt the same combined structure, that is, both include at least a first guide rail section 2511 and a second guide rail section 2512, so that the outer guide rail 251 and the inner guide rail 252 can achieve synchronous extension changes to adapt to the tensioning operation of the transmission chain 21. In some embodiments, the outer guide rail 251 and the inner guide rail 252 share the first guide rail segment 2511 and the second guide rail segment 2512, that is, the first guide rail segment 2511 is a portion of the chain guide 25 around the driven sprocket 23, and the second guide rail segment 2512 is a portion of the chain guide 25 around the driving sprocket 22. Therefore, it is only necessary to respectively set the two ends of the first guide rail segment 2511 and the two ends of the second guide rail segment 2512 to the overlapping fitting surface, so that the overlapping fitting of the outer guide rail 251 and the inner guide rail 252 can be achieved, which is convenient for synchronous adjustment, has high adjustment accuracy, and good synchronization.

[0050] In some embodiments, the chain transmission assembly 2 further includes a guide rail support rod 26, and two guide rail support rods 26 are provided. The first guide rail section 2511 and the second guide rail section 2512 are respectively connected to the two guide rail support rods 26, and the first guide rail section 2511 or the second guide rail section 2512 is adjustably connected to the guide rail support rod 26, or,

[0051] The first guide rail segment 2511 and the second guide rail segment 2512 are both fixedly connected to the guide rail support rod 26 , and one guide rail support rod 26 is connected to the driven sprocket 23 .

[0052] like Figure 4 There are at least two guide rail support rods 26, which are used to support the first guide rail section 2511 and the second guide rail section 2512 respectively. When the first guide rail section 2511 and the second guide rail section 2512 are respectively fixedly connected to the two guide rail support rods 26, at least one guide rail support rod 26 is connected to the driven sprocket 23 through the bearing sleeve to achieve synchronous movement; or the guide rail support rod 26 and the driven sprocket 23 are simultaneously connected to the tensioning mechanism to achieve synchronous movement adjustment, reducing the installation of the bearing sleeve component. When at least one of the first guide rail section 2511 and the second guide rail section 2512 is movably connected to the guide rail support rod 26, the overlap length between the first guide rail section 2511 and the second guide rail section 2512 is adjusted by adjusting the relative position of the first guide rail section 2511 or the second guide rail section 2512 on the guide rail support rod 26. When multiple chain transmission assemblies 2 share the guide rail support rod 26, the tensioning movement of the transmission chains 21 and the adaptation movement of the chain guide rails 25 of the multiple chain transmission assemblies 2 can be simultaneously and synchronously controlled, which greatly improves the adjustment efficiency and accuracy, has better synchronization, and balances the forces between the multiple sections of the transmission chains 21, which is beneficial to increasing the service life.

[0053] In some embodiments, a cover inlet cover channel 4 and a cover outlet cover channel 5 are respectively provided at both ends of the chain cover channel 3 , and the cover inlet cover channel 4 is connected to the chain cover channel 3 via a cover inlet star wheel 6 .

[0054] like Figure 1 As shown, the cap inlet channel 4 is a cap channel for connecting the cap supply system. After the caps 200 first enter the cap inlet channel 4, they are transported downward and turn and separate under the action of the cap inlet star wheel 6, and then enter the chain cap channel 3. The paddle 24 on the transmission chain 21 transports and paddles the caps 200 at the outlet end of the cap inlet star wheel 6. The caps 200 successively enter the chain cap channel 3 for transportation, and turn to enter the next chain cap channel 3 after passing through the driven sprocket 23. The outlet end of the next chain cap channel 3 is connected to the cap outlet channel 5, which is used to transport the caps 200 to the filling machine. The cap outlet channel 5 transports the caps 200 downward through the inclined structure, and the caps 200 sterilized in the sterilization chamber 101 are transported to the next process.

[0055] In some embodiments, along the conveying direction of the transmission chain 21, the chain cover track 3 includes at least a first cover track 31 and a second cover track 32 overlapping each other, and the length of the overlapping portion between the first cover track 31 and the second cover track 32 is adjustable.

[0056] It can be understood that the chain cover channel 3 is used for the channel for conveying the cover 200. When the transmission chain 21 is tightened and adjusted, the conveying length changes, the distance between adjacent paddles 24 changes, and the chain guide rail 25 is extended accordingly to continuously support the paddles 24. At this time, the chain cover channel 3 needs to be adjusted accordingly, such as Figure 5 and Figure 6 As shown, the first cover channel 31 and the second cover channel 32 overlap each other, and the overlapping length is along the conveying direction of the cover 200. The overlapping method is conducive to adjusting the relative position between the first cover channel 31 and the second cover channel 32, so as to realize the overall length adjustment of the chain cover channel 3, and further helps to ensure the stable conveying of the cover 200 by the paddle 24 to avoid cover blockage.

[0057] In some embodiments, the first cover channel 31 and the second cover channel 32 are respectively connected to the first guide rail segment 2511 and the second guide rail segment 2512 of the outer guide rail 251 to move synchronously.

[0058] It can be understood that the outer guide rail 251 is arranged adjacent to the chain cover channel 3, the paddle 24 is supported on the outer guide rail 251, and the corresponding first cover channel 31 and the second cover channel 32 are respectively arranged corresponding to the first guide rail segment 2511 and the second guide rail segment 2512, which is conducive to simplifying the adjustment steps and processes, realizing one-time synchronous adjustment, and having good adjustment consistency, high precision and high efficiency.

[0059] The embodiment of the utility model further provides a cap sterilizing device, including the chain-type cap conveying device provided in the embodiment of the utility model, to achieve sterilization and conveyance of the cap 200 .

[0060] like Figure 1 The cap disinfection device comprises a box body 100 and a cleaning tank 300. The box body 100 is provided with a cap inlet and a cap outlet. A sterilization chamber 101 is provided in the box body 100. The outlet of the sterilizer generator is no more than 200 mm away from the cap 200 to ensure the sterilization effect of the sterilizer. The cap inlet is used to set a cap inlet channel 4 to connect the cap supply system, and the cap outlet is provided with a cap outlet channel 5 to connect the filling machine. The chain-type cap conveying device provided by the utility model is arranged in the box body 100 and is located in the sterilization chamber 101 between the cap inlet and the cap outlet. The cap 200 is moved and disinfected in the sterilization chamber 101 under the action of the chain-type cap conveying device. The cleaning tank 300 is arranged at the bottom of the box body 100 and is arranged corresponding to the chain-type cap conveying device. The cleaning tank 300 is filled with disinfectant, and at least part of the driving sprocket 22 of the chain-type cap conveying device can be immersed in the disinfectant. The disinfectant can also act as a lubricant for chain movement, reducing the wear of the transmission chain 21.

[0061] like Figure 2 As shown, the width of the cleaning tank 300 should ensure the normal operation of the driving sprocket 22 and the paddle 24 to avoid position interference. The bottom teeth of the driving sprocket 22 can be immersed in the disinfectant, and the transmission chain 21 connected to the driving sprocket 22 can also be disinfected by the disinfectant. The paddle 24 is also disinfected. The immersion disinfection flushing can effectively remove the dust generated by the friction movement of the driving sprocket 22 and the transmission chain 21, ensuring the complete disinfection effect. Figure 3 The cleaning tank 300 is provided with a liquid inlet pipe 301 and an overflow pipe 302. The liquid inlet pipe 301 is used to fill or replenish the disinfectant in the cleaning tank 300, and the overflow pipe 302 is used to control the height of the disinfectant in the cleaning tank 300, and can realize the circulation and renewal of the disinfectant to ensure the disinfection concentration of the disinfectant.

[0062] In some embodiments, a plurality of sterilization chambers 101 are provided in the box body 100 between the cap inlet and the cap outlet, each sterilization chamber 101 is provided with a chain-type cap conveying device, and two adjacent chain-type cap conveying devices are connected via a transition star wheel 7 .

[0063] by Figure 1Taking the illustrated embodiment as an example, six chain-type cover conveying devices are provided in the box body 100 and are separately arranged in six sterilization chambers 101. The transmission chain 21 adopts a standing layout, which occupies a high space, effectively reducing the overall plant area occupied by the equipment, and facilitating the placement and maintenance of the equipment. After passing through each driven sprocket 23, the cover 200 turns to enter the next chain cover channel 3. After passing through each transition star wheel 7, the cover 200 is again divided into covers and turned to enter the next chain cover channel 3, and is turned and conveyed multiple times in this way. According to the time requirements of the sterilization process, any number of chain-type cover conveying devices can be set in the box body 100, and they can be matched according to the conveying length and conveying speed of each chain-type cover conveying device to meet the disinfection and conveying requirements.

[0064] In some embodiments, an isolation chamber 400 is provided on the outside of the box body 100, a cover inlet channel 4 of the chain-type cover conveying device is provided in the isolation chamber 400, and an exhaust port 401 is provided on the isolation chamber 400 to connect to an exhaust assembly.

[0065] like Figure 1 and Figure 2 By connecting an exhaust component, such as an exhaust fan, to the exhaust port 401 of the isolation chamber 400, the air in the isolation chamber 400 can be extracted, thereby reducing the gas pressure in the isolation chamber 400, so that the gas pressure in the isolation chamber 400 is less than the gas pressure in the sterilization chamber 101. The gas can only flow from the sterilization chamber 101 to the isolation chamber 400 in one direction, thereby preventing the air in the sterilization chamber 101 from mixing with the external air, thereby achieving air isolation in the sterilization chamber 101, and helping to improve the sterilization effect. In this embodiment, in order to meet the requirement of directional flow of airflow in each working section during the production process, turbulence of gas in different working positions is prevented, which may cause gas mixing and affect the safety of aseptic production, or leakage of sterilized gas and threaten the life safety of production personnel, the box 100 is provided with an isolation chamber 400 and a sterilization chamber 101, and the air pressure relationship is as follows: the air pressure in the isolation chamber 400 is the lowest, which is lower than the external air pressure and the air pressure in the sterilization chamber 101, so that both the external air and the air in the sterilization chamber 101 flow to the isolation chamber 400, and the air in the sterilization chamber 101 is prevented from passing through the isolation chamber 400 and overflowing to the outside. The pressure in the sterilization chamber 101 is lower than the pressure in the filling machine, so that the air flows from the filling machine to the sterilization chamber 101, and the air in the sterilization chamber 101 is prevented from entering the filling machine and affecting the safety of product production.

[0066] In some embodiments, the cover disinfection device further comprises an air blowing device 8, which is disposed above the cleaning tank 300 and located on the exit side of the transmission chain 21 on the driving sprocket 22 and is disposed directly opposite to the transmission chain 21. Thus, the driving sprocket 22, the transmission chain 21 and the paddle 24 just exiting the cleaning tank 300 can be blown dry, mainly to eliminate the contact between the disinfectant and the cover 200.

[0067] In some embodiments, a COP / SOP nozzle 102 is provided on the side wall of the box 100, the nozzle of the COP / SOP nozzle 102 is arranged toward the inside of the box 100, and a COP / SOP drain pipe 103 is provided at the bottom of the box 100. The COP / SOP nozzle 102 and the COP / SOP drain pipe 103 are used to automatically clean or disinfect the inside of the box 100 and eliminate dust and other pollutants generated in the box 100. COP / SOP is a conventional aseptic cleaning and disinfection solution in the filling field.
