Description

Technical Field

[0001] This application relates to the field of specialized intelligent packaging equipment technology, and more specifically, to an intelligent transport and processing device for cosmetic packaging bottles. Background Technology

[0002] In the current cosmetic packaging bottle processing industry, most adopt a segmented processing mode, with each processing step relying on independent conveying equipment for connection. The conveying gaps are large, and the lateral (perpendicular to the conveying direction) positioning error is large, causing the packaging bottles to shift during the transfer process, which reduces the accuracy of subsequent processing.

[0003] The above problems urgently need to be addressed. Summary of the Invention

[0004] The purpose of this application is to provide an intelligent processing device for cosmetic packaging bottles, which has the advantages of reducing lateral positioning errors during transportation and preventing the packaging bottles from shifting during transfer, thereby solving the above-mentioned problems.

[0005] This application provides an intelligent processing device for cosmetic packaging bottles, the technical solution of which is as follows: It includes multiple conveying components and an injection molding mechanism, a bottle mouth grinding mechanism, a surface printing mechanism, and a vacuum coating mechanism arranged in sequence. The conveying components are all arranged at the lower station of the injection molding mechanism, the bottle mouth grinding mechanism, the surface printing mechanism, and the vacuum coating mechanism. Two adjacent conveying components are connected end to end. Each of the conveying components includes a bracket, a conveyor belt disposed on top of the bracket along its length, and a plurality of positioning clamps disposed on the conveyor belt along the conveying direction. The bracket is provided with a protrusion and a groove at both ends along its length. The groove has a U-shaped vertical cross-section, with its top opening facing upward and its side opening facing the length direction of the bracket. The shape of the protrusion is adapted to the shape of the groove. The protrusion has a first positioning hole in the vertical direction, and the bottom of the groove has a corresponding second positioning hole in the vertical direction. After the protrusion and the adjacent groove are fitted and engaged, they are connected and fixed by inserting the first positioning pin into the first positioning hole and the second positioning hole in sequence. The bracket is rotatably provided with a connecting plate near the end of the conveyor belt. When the connecting plate is rotated to a horizontal position, the top surface of the connecting plate is flush with the top surface of the conveyor belt. When the protrusion is fitted and engaged with the adjacent groove, the two adjacent connecting plates are seamlessly aligned and spliced. It also includes a control system, which consists of a PLC and a touch screen. Each of the conveying components is equipped with a corresponding conveying motor, and the conveying motor is electrically connected to the control system.

[0006] The intelligent processing device for cosmetic packaging bottles provided in this application includes multiple conveying components and an injection molding mechanism, a bottle mouth grinding mechanism, a surface printing mechanism, and a vacuum coating mechanism arranged sequentially. Each of the injection molding mechanism, the bottle mouth grinding mechanism, the surface printing mechanism, and the vacuum coating mechanism has a conveying component located below it. Adjacent conveying components are connected end-to-end. In this embodiment, the injection molding mechanism, the bottle mouth grinding mechanism, the surface printing mechanism, and the vacuum coating mechanism are all existing mature equipment. In traditional processing devices, injection molding, grinding, printing, and coating processes often use independent equipment, requiring manual material handling, which is not only time-consuming but also prone to errors due to manual operation. To address the issue of misaligned or damaged packaging bottles, multiple interconnected conveyor components are used as transport carriers, placed in corresponding processing stations to automate the entire process of raw material handling, molding, grinding, printing, and coating. This shortens material transport time. The materials refer to unprocessed packaging bottle blanks. Each processing mechanism is precisely aligned with the conveyor components. The conveyor components can adjust their speed according to the rhythm of different processing steps via a control system, preventing waiting or accumulation at any stage and improving the overall process flow. Each conveyor component includes a support frame, a conveyor belt positioned on top of the support frame along its length, and multiple positioning clamps positioned on the conveyor belt along its transport direction. The support frame serves as the mounting carrier for the conveyor belt and the positioning clamps. The bracket has protrusions and grooves at both ends along its length. The grooves have a U-shaped vertical cross-section, with the top opening facing upwards and the side openings facing the length of the bracket. This orientation of the groove openings facilitates precise docking between adjacent conveying components and effectively limits lateral displacement. The shape of the protrusions matches the shape of the grooves, ensuring effective positioning of adjacent conveying components after docking and preventing lateral displacement. The protrusions have a first positioning hole along the vertical direction, and the bottom of the grooves has a corresponding second positioning hole along the vertical direction. After the protrusions and adjacent grooves are fitted together, the first positioning hole... Positioning pins are sequentially inserted into the first positioning hole and the second positioning hole for connection and fixation. Traditional conveying components often use a planar docking method when connecting, which results in a large lateral positioning error and is prone to loosening due to vibration after long-term operation. This application restricts the lateral freedom of the conveying component by using the matching snap-fit ​​method of the protrusion and groove, combined with the lateral fixation of the first positioning pin, to prevent the conveying component from shifting laterally, directly reducing the lateral positioning error during the conveying process and preventing the packaging bottle from shifting during the transfer. In addition, the guide snap-fit ​​design of the protrusion and groove eliminates the need for repeated calibration when connecting adjacent conveying components. When a certain group of components needs to be maintained separately, the positioning pin can be pulled out to separate them, improving the convenience of maintenance.The bracket has a connecting plate rotatably mounted near the end of the conveyor belt. When the connecting plate is rotated to a horizontal position, its top surface is flush with the top surface of the conveyor belt. When the protrusion engages with the adjacent groove, the two adjacent connecting plates are seamlessly aligned. Traditional conveyor assembly joints are prone to bottle jamming or tilting due to height differences, affecting subsequent processing and easily resulting in defective products. In this application, the connecting plate, when rotated to a horizontal position, is flush with the top surface of the conveyor belt, and adjacent connecting plates are seamlessly joined, ensuring the bottle remains stable during transport and preventing jamming or tilting. Furthermore, when cleaning the conveyor assembly or maintaining the processing mechanism, the connecting plate can be flipped to create operating space, increasing its versatility. The system also includes a control system, which consists of a PLC and... The system comprises a touchscreen, and each conveying component is equipped with a corresponding conveyor motor, which is electrically connected to the control system. Traditional equipment often uses a single-unit control system; a failure in one conveying component requires a complete shutdown, leading to a drastic reduction in production. In this application, each conveying component is equipped with an independent conveyor motor, allowing the control system to individually control the start and stop of a specific group of components while maintaining normal operation of other conveying components. This significantly reduces production losses due to downtime. Simultaneously, it can coordinate the conveying speeds of each component, ensuring collaborative processing across multiple processes. For example, after injection molding, the corresponding conveying component automatically accelerates to transfer the semi-finished product to the polishing station. The semi-finished product refers to the unfinished packaging bottle. The touchscreen has a visual interface that displays the real-time operating status of each conveying component, such as speed, temperature, and fault information, facilitating adjustments to the parameters of the conveying components by staff based on actual processing needs.

[0007] Furthermore, in this application, a second cylinder is embedded downward at the bottom of each of the four corners of the bracket, and a caster wheel is connected downward at the output end of the second cylinder; The bracket is provided with a sleeve along the output direction of the second cylinder. The sleeve is sleeved around the circumferential outside of the second cylinder. The bottom surface of the sleeve is lower than the output surface of the second cylinder. The output surface refers to the end face of the second cylinder that extends out of the piston rod.

[0008] The intelligent processing device for cosmetic packaging bottles provided in this application features a second cylinder embedded downwards at each of the four corners of the support frame. The output end of each second cylinder is connected downwards to a caster wheel. Traditional conveying components are mostly fixed installations, requiring three to four people to move them, resulting in low efficiency. In contrast, this solution extends the caster wheel by activating the second cylinder, allowing one person to push the conveying component. After installation and positioning, the second cylinder is retracted, and the support frame is flush with the ground, preventing the conveying component from shifting due to vibration during material transport. Furthermore, cosmetic production workshops often need to adjust equipment layout according to order changes. Based on the above structure, the conveying component moves flexibly, and the processing layout can be adjusted promptly to meet actual processing needs. The support has a sleeve along the output direction of the second cylinder. The sleeve is fitted around the circumferential outside of the second cylinder, and the bottom surface of the sleeve is lower than the output surface of the second cylinder. The output surface refers to the end face of the piston rod extending from the second cylinder. When the piston rod of a traditional cylinder is in direct contact with the ground, it is easy for impurities on the ground to stick to the side wall of the piston rod, causing scratches or jamming. In this solution, the bottom surface of the sleeve is lower than the output surface of the second cylinder, which can prevent impurities from contacting the piston rod and at the same time guide the piston rod, preventing the piston rod from bending due to lateral forces. For example, the friction when pushing the conveying component causes the piston rod to be subjected to lateral forces, effectively preventing the movement of the conveying component from being obstructed due to the failure of the second cylinder.

[0009] Furthermore, in this application, a beryllium copper elastic sheet is provided between the protrusion and the adjacent groove.

[0010] The intelligent processing device for cosmetic packaging bottles provided in this application uses steel for the support of the conveying component, which has a coefficient of thermal expansion of 11.5×10-6 / ℃. Under the temperature variation of 0~40℃ in the workshop, the expansion and contraction of each meter of support is about 0.46mm. In long-term conveying applications, gaps are prone to appear at the connection points between the conveying components, leading to increased vibration. Therefore, a beryllium copper elastic sheet is placed between the protrusion and the adjacent groove. The coefficient of thermal expansion of beryllium copper is 16.6×10-6 / ℃, and the elastic modulus is 130GPa. The beryllium copper elastic sheet can achieve adaptive expansion and contraction with a compensation amount of 0~0.5mm, filling the gaps caused by temperature changes, ensuring that the protrusion and groove are always tightly fitted, preventing lateral displacement of the conveying component, and ensuring the positioning accuracy of the packaging bottle during the conveying process. In addition, the yield strength of beryllium copper is ≥1000Mpa. The beryllium copper elastic sheet can absorb the vibration energy generated by the operation of the conveying component, reducing the noise from the traditional 75dB to ≤65dB, thereby reducing vibration and improving the workshop working environment.

[0011] Furthermore, in this application, the positioning clamp is a pneumatic gripper, the bottom of the pneumatic gripper is connected to a slider, the conveyor belt is provided with a groove along the conveying direction, the slider is slidably engaged with the groove, and the slider is provided with a first cylinder for driving the pneumatic gripper to adjust the clamping size, and the first cylinder is electrically connected to the control system.

[0012] The intelligent processing device for cosmetic packaging bottles provided in this application addresses the issue that traditional clamps are often fixed to conveyor belts. However, conveyor belts are not rigid materials that are difficult to deform, and clamps are prone to movement and displacement due to conveyor belt deformation. Therefore, in this embodiment, the positioning clamp is a pneumatic gripper with a slider connected to its bottom. The conveyor belt has a groove along the conveying direction, and the slider slides into the groove. This sliding engagement structure facilitates the installation of the positioning clamp while limiting its lateral displacement, improving the movement accuracy of the clamp along the conveying direction, ensuring alignment between the packaging bottle and the processing mechanism, and facilitating the precision of subsequent processing. Pre-processing; the slider is internally equipped with a first cylinder for driving the pneumatic gripper to adjust the clamping size. The first cylinder is electrically connected to the control system. Traditional clamps require manual replacement of the gripper to adapt to different sized packaging bottles. This solution adjusts the clamping size of the pneumatic gripper through the first cylinder to adapt to different sized packaging bottles, meeting the processing needs of small batch and multi-variety orders. The control system can also automatically send instructions to the first cylinder to adjust the clamping size of the pneumatic gripper based on the bottle shape size collected by the vision recognition component, without manual intervention, thus improving automation. At the same time, it can store multiple sets of bottle shape parameters, which can be directly called in the next processing, shortening the parameter setting time.

[0013] Furthermore, in this application, a pressure sensor is provided at the working end of the pneumatic gripper, and the pressure sensor is electrically connected to the control system.

[0014] Furthermore, in this application, the working end of the pneumatic gripper is provided with an injection-molded hybrid layer, which is a composite material of nylon and glass fiber.

[0015] Furthermore, this application also includes a locking assembly, which includes a cross block, a screw, and a cross locking member. The cross block has a first threaded hole in its middle along its length. The screw is threaded through the first threaded hole. One end of the screw is provided with a limit nut, and the other end of the screw is threaded to the cross locking member. The length of the screw is greater than the length of the first threaded hole, and the radial dimension of the limit nut is greater than the diameter of the first threaded hole. The bracket has cross holes at both ends along its length. A limit baffle is provided on the side of the cross block near the limit nut. The radial dimension of the limit baffle is greater than the radial dimension of the cross hole. The projections of the cross hole, the cross block, and the cross lock are the same along the length. The cross block is inserted into the two cross holes of the adjacent brackets to form an aligned and fitted connection.

[0016] Furthermore, in this application, the bracket is provided with a plurality of infrared sensors along the conveying direction, the infrared sensors are highly aligned with the positioning fixture, and the infrared sensors are electrically connected to the control system.

[0017] Furthermore, in this application, the support frame is rotatably provided with a dust cover at the end near the connecting plate. When the dust cover rotates to above the connecting plate, it covers the connecting plate. The distance between the dust cover and the connecting plate is greater than the height of the positioning fixture. The dust cover is made of transparent material.

[0018] Furthermore, in this application, the support is provided with multiple visual recognition components along the conveying direction. The visual recognition components include an image processor, a laser contour sensor, and an industrial camera. The image processor, the laser contour sensor, and the industrial camera are all highly aligned with the positioning fixture, and the image processor, the laser contour sensor, and the industrial camera are all electrically connected to the control system.

[0019] Other features and advantages of this application will be set forth in the following description and will be apparent in part from the description or may be learned by practicing embodiments of this application. The objectives and other advantages of this application may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0020] Beneficial effects: This application achieves fully automated transfer by cooperating with multiple conveying components connected end to end and multiple processing mechanisms. Each conveying component can dynamically adjust its speed according to the process rhythm, avoiding process waiting. Among them, adjacent conveying components are connected and limited by the cooperation of protrusions, grooves and positioning pins, which restricts the lateral movement freedom of the conveying components. The seamless splicing of the connecting plates eliminates the jamming problem during the transfer process and improves the smoothness of the packaging bottles during transfer. In summary, the above structure reduces the lateral positioning error during the conveying process, prevents the packaging bottles from shifting during the transfer process, and improves the positioning accuracy of the packaging bottles during the transfer process.

[0024] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Please refer to Figures 1 to 15As shown, this application provides an intelligent processing device for cosmetic packaging bottles, including multiple conveying components 1 and sequentially arranged injection molding mechanism 2, bottle mouth grinding mechanism 3, surface printing mechanism 4, and vacuum coating mechanism 5. Conveying components 1 are all located below the injection molding mechanism 2, bottle mouth grinding mechanism 3, surface printing mechanism 4, and vacuum coating mechanism 5, with adjacent conveying components 1 connected end-to-end. Each conveying component 1 includes a support 6, a conveyor belt 7 arranged along its length on top of the support 6, and multiple positioning clamps 8 arranged along the conveying direction on the conveyor belt 7. The support 6 has protrusions 9 and grooves 10 at both ends along its length. The vertical cross-section of the groove 10 is U-shaped, with the top opening of the groove 10 facing upwards and the side openings of the groove 10 facing the length direction of the support 6. The shape of the protrusions 9 is similar to that of the grooves 10. The shape of the groove 10 is adapted; the protrusion 9 is provided with a first positioning hole 11 in the vertical direction, and the bottom of the groove 10 is provided with a second positioning hole 12 in the vertical direction. After the protrusion 9 is adapted and engaged with the adjacent groove 10, it is connected and fixed by inserting the first positioning pin 13 into the first positioning hole 11 and the second positioning hole 12 in sequence; the bracket 6 is rotatably provided with a connecting plate 14 near the end of the conveyor belt 7. When the connecting plate 14 is rotated to the horizontal position, the top surface of the connecting plate 14 is flush with the top surface of the conveyor belt 7. When the protrusion 9 is adapted and engaged with the adjacent groove 10, the two adjacent connecting plates 14 are seamlessly aligned and spliced; it also includes a control system 15, which consists of a PLC and a touch screen 16. Each conveying component 1 is provided with a corresponding conveying motor 17, and the conveying motor 17 is electrically connected to the control system 15.

[0026] Specifically, in the current cosmetic packaging bottle processing industry, most adopt a segmented processing mode, with each processing step relying on independent conveying equipment for connection. This results in large conveying gaps and significant lateral positioning errors, causing the packaging bottles to shift during transport and reducing the accuracy of subsequent processing. To address these issues, the intelligent processing device for cosmetic packaging bottles provided in this application includes multiple conveying components 1 and sequentially arranged injection molding mechanism 2, bottle mouth grinding mechanism 3, surface printing mechanism 4, and vacuum coating mechanism 5. Conveying components 1 are located below each of the injection molding mechanism 2, bottle mouth grinding mechanism 3, surface printing mechanism 4, and vacuum coating mechanism 5, with adjacent conveying components 1 connected end-to-end. In this embodiment, the injection molding mechanism 2, bottle mouth grinding mechanism 3, surface printing mechanism 4, and vacuum coating mechanism 5 are all existing mature equipment. In traditional processing devices, injection molding, grinding, printing, and coating processes often use independent equipment, requiring manual material transfer, which is not only time-consuming but also prone to bottle shifting or damage due to manual operation. Therefore, multiple end-to-end connected conveying components 1 serve as the conveying carrier, placed at the corresponding processing stations. The area enables fully automated transfer of raw materials, forming, grinding, printing, and coating processes, shortening material transfer time. The materials refer to unprocessed packaging bottle blanks. Each processing mechanism is precisely aligned with the conveyor assembly 1. The conveyor assembly 1 can adjust its conveying speed according to the rhythm of different processing steps via the control system 15, avoiding waiting or accumulation at any step and improving the overall process smoothness. Each conveyor assembly 1 includes a support 6, a conveyor belt 7 positioned on top of the support 6 along its length, and multiple positioning clamps 8 positioned on the conveyor belt 7 along the conveying direction. The support 6 serves as the conveyor belt. The mounting carriers for 7 and positioning clamps 8, the bracket 6 is provided with protrusions 9 and grooves 10 at both ends along the length direction. The vertical cross section of the groove 10 is U-shaped. The top opening of the groove 10 faces upward and the side opening of the groove 10 faces the length direction of the bracket 6. The opening direction of the groove 10 not only facilitates the precise docking between adjacent conveying components 1, but also plays a good role in limiting the lateral displacement of the conveying components 1. The shape of the protrusion 9 matches the shape of the groove 10 to ensure the limiting effect of adjacent conveying components 1 after docking and prevent the conveying components 1 from shifting laterally.The protrusion 9 has a first positioning hole 11 vertically, and the bottom of the groove 10 has a corresponding second positioning hole 12 vertically. After the protrusion 9 and the adjacent groove 10 are fitted and engaged, they are connected and fixed by inserting the first positioning pin 13 into the first positioning hole 11 and the second positioning hole 12 in sequence. Traditionally, the conveying assembly 1 is connected by a planar butt joint, which results in a large lateral positioning error and is prone to loosening due to vibration after long-term operation. This application restricts the lateral freedom of the conveying assembly 1 by using the fitting and engaging method between the protrusion 9 and the groove 10, combined with the lateral fixation of the first positioning pin 13, thus preventing the lateral displacement of the conveying assembly 1 and directly reducing the lateral positioning error during the conveying process, preventing the packaging bottles from being misaligned during the transfer process. In addition, the guide-type snap-fit ​​design of the protrusion 9 and the groove 10 eliminates the need for repeated calibration when docking adjacent conveying components 1. When a component needs to be maintained individually, it can be separated by pulling out the positioning pin, improving maintenance convenience. The bracket 6 is rotatably equipped with a connecting plate 14 near the end of the conveyor belt 7. When the connecting plate 14 is rotated to the horizontal position, the top surface of the connecting plate 14 remains flush with the top surface of the conveyor belt 7. During actual conveying, the packaging bottles on the conveyor belt 7 slide across the upper surface of the connecting plate 14 according to the conveying direction under the action of conveying inertia and arrive at the next conveyor belt 7, achieving precise conveying without lateral offset. When the protrusion 9 and the adjacent groove 10 are fitted and snapped together, the two adjacent connecting plates 14 maintain seamless alignment and splicing. Traditional conveyor components 1 are prone to jamming or tilting of packaging bottles due to height differences at their joints, affecting subsequent processing and easily resulting in defective products. In this application, the connecting plate 14, when rotated to a horizontal position, is flush with the top surface of the conveyor belt 7, and adjacent connecting plates 14 are seamlessly joined, ensuring the packaging bottles maintain a stable posture during transport and preventing jamming or tilting. Furthermore, when cleaning the conveyor component 1 or maintaining the processing mechanism, the connecting plate 14 can be flipped to free up operating space, increasing its applicability. The system also includes a control system 15, composed of a PLC and a touch screen 16. Each conveyor component 1 is equipped with a corresponding conveyor motor 17, which is electrically connected to the control system 15. Traditional equipment is mostly integrated. In this application, a malfunction in one conveyor component 1 necessitates a complete shutdown, leading to a drastic reduction in production output. Each conveyor component 1 in this application is equipped with an independent conveyor motor 17. The control system 15 can individually control the start and stop of a specific group of components while maintaining normal operation of other conveyor components 1, significantly reducing production losses due to downtime. Simultaneously, it can coordinate the conveying speeds of each conveyor component 1 to ensure collaborative processing across multiple processes. For example, after injection molding, the corresponding conveyor component 1 automatically accelerates to transfer the semi-finished product to the polishing station. The semi-finished product refers to the unfinished packaging bottle. The touchscreen 16 has a visual interface that displays the real-time operating status of each conveyor component 1, such as speed, temperature, and fault information, allowing staff to adjust the parameters of each conveyor component 1 according to actual processing needs.

[0027] In some preferred embodiments, a second cylinder 18 is embedded and lowered at the bottom of the four corners of the bracket 6, and a caster wheel 19 is connected to the output end of the second cylinder 18 facing downward; a sleeve 20 is provided on the bracket 6 along the output direction of the second cylinder 18, and the sleeve 20 is sleeved on the circumferential outside of the second cylinder 18. The bottom surface of the sleeve 20 is lower than the output surface of the second cylinder 18, and the output surface refers to the end face of the second cylinder 18 that extends out of the piston rod.

[0028] Specifically, a second cylinder 18 is embedded downwards at the bottom of each of the four corners of the bracket 6. The output end of the second cylinder 18 is connected downwards to a caster wheel 19. Traditional conveying components 1 are mostly fixed installations, requiring three to four people to move them, resulting in low efficiency. In this solution, activating the second cylinder 18 extends the caster wheel 19, allowing one person to push the conveying component 1. After installation and positioning, the second cylinder 18 is retracted, and the bracket 6 is flush with the ground, preventing the conveying component 1 from shifting due to vibration during material transport. Furthermore, cosmetic production workshops often need to adjust equipment layout according to order changes. Based on the above structure, the conveying component 1 moves flexibly, and the processing layout can be adjusted promptly to meet actual processing needs. A sleeve 20 is provided along the output direction of the second cylinder 18. The sleeve 20 is sleeved around the circumference of the second cylinder 18. The bottom surface of the sleeve 20 is lower than the output surface of the second cylinder 18. The output surface refers to the end face of the piston rod of the second cylinder 18 that extends outward. When the piston rod of a traditional cylinder is in direct contact with the ground, it is easy for impurities on the ground to stick to the side wall of the piston rod, causing the piston rod to be scratched or stuck. In this solution, the bottom surface of the sleeve 20 is lower than the output surface of the second cylinder 18, which can prevent impurities from contacting the piston rod. At the same time, it plays a guiding role for the piston rod, preventing the piston rod from bending due to lateral force. For example, when pushing the conveying component 1, the friction causes the piston rod to be subjected to lateral force, effectively preventing the conveying component 1 from being obstructed due to the failure of the second cylinder 18.

[0029] In some preferred embodiments, a beryllium copper elastic sheet is provided between the protrusion 9 and the adjacent groove 10.

[0030] Specifically, the support 6 of the conveying assembly 1 is made of steel with a coefficient of thermal expansion of 11.5×10-6 / ℃. Under the temperature variation of 0~40℃ in the workshop, the expansion and contraction of each meter of support 6 is about 0.46mm. In long-term conveying applications, gaps are prone to appear at the joints between the conveying assemblies 1, leading to increased vibration. Therefore, a beryllium copper elastic sheet is placed between the protrusion 9 and the adjacent groove 10. The coefficient of thermal expansion of beryllium copper is 16.6×10-6 / ℃, and the elastic modulus is 130GPa. The beryllium copper elastic sheet can achieve adaptive expansion and contraction with a compensation amount of 0~0.5mm, filling the gaps caused by temperature changes and ensuring that the protrusion 9 and the groove 10 are always tightly fitted, preventing the conveying assembly 1 from shifting laterally and ensuring the positioning accuracy of the packaging bottle during the conveying process. In addition, the yield strength of beryllium copper is ≥1000Mpa. The beryllium copper elastic sheet can absorb the vibration energy generated by the operation of the conveying assembly 1, reducing the noise from the traditional 75dB to ≤65dB, thereby reducing vibration and improving the workshop working environment.

[0031] In some preferred embodiments, the positioning clamp 8 is a pneumatic gripper, the bottom of which is connected to a slider 21. The conveyor belt 7 has a groove 22 along the conveying direction. The slider 21 is slidably engaged with the groove 22. The slider 21 is equipped with a first cylinder 29 for driving the pneumatic gripper to adjust the clamping size. The first cylinder 29 is electrically connected to the control system 15.

[0032] Specifically, traditional clamps are mostly fixed to the conveyor belt 7. However, the conveyor belt 7 is not a rigid material that is difficult to deform, and the clamps are prone to movement and displacement due to deformation of the conveyor belt 7. Therefore, in this embodiment, the positioning clamp 8 is a pneumatic gripper. The bottom of the pneumatic gripper is connected to a slider 21. The conveyor belt 7 has a groove 22 along the conveying direction. The slider 21 and the groove 22 are slidably engaged. Through the sliding engagement structure between the slider 21 and the groove 22, the positioning clamp 8 is easy to install while limiting the lateral displacement of the positioning clamp 8, improving the movement accuracy of the clamp along the conveying direction, ensuring that the packaging bottle is aligned with the processing mechanism, and facilitating the precise processing of the subsequent processing mechanism; slider 21 The internal structure includes a first cylinder 29 for driving the pneumatic grippers to adjust the clamping size. The first cylinder 29 is electrically connected to the control system 15. Traditional clamps require manual replacement of the grippers to adapt to different sizes of packaging bottles. This solution adjusts the clamping size of the pneumatic grippers using the first cylinder 29 to adapt to different sizes of packaging bottles, meeting the processing needs of small-batch, multi-variety orders. The control system 15 can also automatically send instructions to the first cylinder 29 to adjust the clamping size of the pneumatic grippers based on the bottle shape dimensions collected by the vision recognition component 28, without manual intervention, thus improving automation. It can also store multiple sets of bottle shape parameters for direct recall during subsequent processing, shortening parameter setting time. In practical applications, the upper surface of the connecting plate 14 can be set to be flush with the sliding surface of the chute 22. Based on this structure, the packaging bottles located in the chute 22 slide across the upper surface of the connecting plate 14 under the action of conveying inertia and arrive at the chute 22 of the next conveyor belt 7, achieving precise conveying without lateral offset. The sliding surface refers to the upper surface of the groove 22 that contacts the bottom surface of the slider 21.

[0033] In some preferred embodiments, a pressure sensor 23 is provided at the working end of the pneumatic gripper, and the pressure sensor 23 is electrically connected to the control system 15.

[0034] Specifically, traditional clamps have a fixed clamping force, which can easily lead to deformation due to excessive tightness or displacement due to differences in bottle material or size. Therefore, in this embodiment, a pressure sensor 23 is provided at the working end of the pneumatic gripper. The pressure sensor 23 is electrically connected to the control system 15. The pressure sensor 23 monitors the clamping force of the pneumatic gripper in real time and feeds it back to the control system 15 to adjust the output pressure of the first cylinder 29, ensuring that the clamping force is stable within the force range suitable for the cosmetic bottle. This prevents the packaging bottle from deforming and being damaged, while ensuring the correct posture of the packaging bottle and avoiding displacement. The data from the pressure sensor 23 can be stored in the control system 15 in real time, making it convenient to trace the clamping force parameters of each packaging bottle. If a quality problem occurs, such as bottle deformation, it can be quickly located and investigated whether it is caused by abnormal clamping force, thus improving the efficiency of quality traceability.

[0035] In some preferred embodiments, the working end of the pneumatic gripper is provided with an injection-molded hybrid layer 24, which is a composite material of nylon and glass fiber.

[0036] Specifically, traditional grippers are mostly made of pure nylon, which has poor wear resistance and is prone to decreased clamping accuracy due to wear from debris during the grinding process. Therefore, in this embodiment, the working end of the pneumatic gripper is provided with an injection-molded hybrid layer 24. The injection-molded hybrid layer 24 is a composite material of nylon and glass fiber. The tensile strength of the injection-molded hybrid layer 24 is ≥80MPa, which greatly improves wear resistance while maintaining toughness to prevent the pneumatic gripper from breaking upon impact. In addition, processes such as bottle mouth grinding and vacuum coating are prone to generating dust and high temperatures. The high temperature resistance and corrosion resistance of the injection-molded hybrid layer 24 are better than those of pure nylon, allowing it to work stably in harsh environments and ensuring the accurate clamping of the positioning fixture 8 during long-term processing, preventing the packaging bottle from shifting during transportation.

[0037] In some preferred embodiments, the pneumatic gripper is provided with a silicone pad 25 on the outside of the injection-molded mixing layer 24.

[0038] Specifically, traditional metal or hard plastic grippers can easily scratch the surface of packaging bottles, especially the surface of finished packaging bottles after coating, which is more fragile. Therefore, in this embodiment, a silicone pad 25 is provided on the outside of the injection-molded mixing layer 24 of the pneumatic gripper. The silicone pad 25 is soft and has a high coefficient of friction, which can not only enhance the clamping stability and prevent the packaging bottle from rotating, but also buffer the clamping force and prevent scratches on the surface of the packaging bottle. In addition, the silicone pad 25 has good chemical stability and does not react with the commonly used materials of cosmetic packaging bottles, such as PET, PP, and glass, nor will it cause contamination due to contact with inks or coating agents, ensuring that the packaging bottle meets cosmetic hygiene standards, such as heavy metal content ≤10mg / kg.

[0039] In some preferred embodiments, a locking assembly 30 is also included. The locking assembly 30 includes a cross block 31, a screw 32, and a cross locking member 33. A first threaded hole 34 is formed in the middle of the cross block 31 along the length direction. The screw 32 is threaded through and connected to the first threaded hole 34. A limit nut 35 is provided at one end of the screw 32, and the other end of the screw 32 is threadedly connected to the cross locking member 33. The length of the screw 32 is greater than the length of the first threaded hole 34, and the radial dimension of the limit nut 35 is greater than the diameter of the first threaded hole 34. Cross holes 36 are formed at both ends of the bracket 6 along the length direction. A limit baffle 37 is provided on the side of the cross block 31 near the limit nut 35. The radial dimension of the limit baffle 37 is greater than the radial dimension of the cross hole 36. The projections of the cross holes 36, the cross block 31, and the cross locking member 33 along the length direction are the same. The cross block 31 is inserted into and connected to the two aligned and fitted cross holes 36 of the adjacent bracket 6.

[0040] Specifically, it also includes a locking assembly 30, which includes a cross block 31, a screw 32, and a cross locking member 33. A first threaded hole 34 is formed in the middle of the cross block 31 along its length. The screw 32 is threaded through and connected to the first threaded hole 34. A limit nut 35 is provided at one end of the screw 32, and the other end of the screw 32 is threaded to the cross locking member 33. The length of the screw 32 is greater than the length of the first threaded hole 34. In this case, the screw 32 is longer than the first threaded hole 34 of the cross block 31, so that both ends of the screw 32 can extend out of the cross block 31. A limit nut 35 is provided at one end of the screw 32, and the other end of the screw 32 is connected to the cross locking member 33. This allows for adjustment margin, ensuring that the distance between the cross block 31 and the cross locking member 33 can be adjusted by rotating the screw 32 to accommodate bracket mating surfaces of different thicknesses. The radial dimension of the limiting nut 35 is larger than the diameter of the first threaded hole 34. Since the limiting nut 35 is larger than the first threaded hole 34, when the screw 32 moves to one side, the limiting nut 35 will abut against the end face of the cross block 31, forming a limiting effect and preventing the cross block 31 from coming off the screw 32. The limiting nut 35 at one end of the screw 32 is used to limit the maximum movement position of the cross block 31 on the screw 32 to prevent it from falling off. The other end of the screw 32 is threaded with a cross... The locking element 33 is used to move closer to or further away from the cross block 31 as the screw 32 rotates, thereby clamping or releasing the bracket 6. This forms a rotational locking structure for the locking assembly 30. Specifically, rotating the screw 32 adjusts the relative position between the locking element 33 and the cross block 31 along its length, keeping them aligned or staggered, thus achieving the connection or locking state of the locking assembly 30. The bracket 6 has cross holes 36 at both ends along its length for inserting the cross block 31 and the locking element 33, achieving alignment and connection between adjacent brackets 6. A limiting baffle 37 is provided on the side of the cross block 31 near the limiting nut 35. The radial dimension of the limiting baffle 37 is larger than the radial dimension of the cross hole 36. After the cross block 31 is inserted into the cross hole 36 from one side, the cross block 31 will not come off from this side, thus playing an axial limiting role for the cross block 31. The projections of the cross hole 36, the cross block 31, and the cross lock 33 along the length direction are all the same, ensuring that the cross block 31 and the cross lock 33 can be accurately inserted into the cross hole 36 without gaps, achieving high-precision fit and eliminating positioning errors caused by fit gaps. The cross block 31 is inserted into the two aligned and fitted cross holes 36 of the adjacent bracket 6.

[0041] In practical applications, after the two cross holes 36 of adjacent brackets 6 are aligned and fitted, the screw 32 of the locking assembly 30 is rotated to align the cross locking member 33 with the cross block 31, that is, the projections of the cross locking member 33 and the cross block 31 in the length direction coincide. Then, with the cross locking member 33 of the locking assembly 30 as the leading structure, it is preferentially inserted into the cross hole 36 until the cross locking member 33 extends out of the cross hole 36. At this time, the screw 32 is rotated to move the cross locking member 33 to abut against the bracket 6, and at the same time, the cross locking member 33 and the cross block 31 are aligned. The positions of the locking components 30 and 31 are kept in an interleaved state, meaning that the projections of the cross locking element 33 and the cross block 31 in the length direction are not coincident, which can also be called the locking state. This achieves the locking function of the locking component 30 and realizes the connection and fixation between adjacent brackets 6. When it is necessary to separate adjacent brackets 6, rotate the screw 32 to move the cross locking element 33 away from the bracket 6 until the position of the cross locking element 33 and the cross block 31 are aligned, so that the locking component 30 changes to the unlocked state. This allows the locking component 30 to be pulled away from the bracket 6, realizing the convenient separation of adjacent brackets 6. It should be noted that the locking component 30, together with the protrusion 9 and the groove 10, forms a multi-level positioning and limiting structure, which directly restricts the lateral displacement of the conveying component 1. Among them, the protrusion 9 and the groove 10 are responsible for the main positioning, while the locking component 30 and the cross hole 36 are responsible for auxiliary positioning and anti-torsion. By rotating the screw 32 in the locking assembly 30, the preload can be adjusted, axial and radial clearances can be eliminated, overall rigidity can be improved, and lateral offset of the conveying assembly 1 can be avoided. The threaded preload connection structure and the cross-shaped anti-torsion limiting structure together ensure the positioning and conveying accuracy of the conveying assembly 1 in a high-frequency vibration environment. Compared with the welding or interference fit connection structure, the connection between the locking assembly 30 and the bracket 6 is more convenient to disassemble and assemble, which is suitable for flexible production lines that require frequent module replacement. At the same time, it reduces the lateral positioning error during the conveying process and prevents the packaging bottles from shifting during the transfer.

[0042] In some preferred embodiments, the support 6 is provided with a plurality of infrared sensors 27 along the conveying direction, the infrared sensors 27 are aligned with the positioning fixture 8 at a certain height, and the infrared sensors 27 are electrically connected to the control system 15.

[0043] Specifically, traditional equipment relies on manual inspection of the fixture position. Packaging bottles are prone to fixture displacement due to conveyor vibration. If this is not detected in time, it will affect subsequent processing. Therefore, in this embodiment, the support 6 is equipped with multiple infrared sensors 27 along the conveying direction. The infrared sensors 27 are highly aligned with the positioning fixture 8 and are electrically connected to the control system 15. Through the above structure, the infrared sensors 27 monitor the position of the positioning fixture 8 in real time. When the positioning fixture 8 deviates, the infrared sensors 27 immediately send a signal to the control system 15. The control system 15 adjusts the speed of the conveyor motor 17 to facilitate correction. If the infrared sensors 27 in a certain area frequently detect deviation, it can provide an early warning of whether the conveyor belt 7 is deformed or jammed, and troubleshoot in advance. If the tension of the conveyor belt 7 is insufficient, it can improve the fault prevention rate and avoid sudden shutdown.

[0044] In some preferred embodiments, a dust cover 26 is rotatably provided at the end of the support frame near the connecting plate 14. When the dust cover 26 rotates above the connecting plate 14, it covers the connecting plate 14. The distance between the dust cover 26 and the connecting plate 14 is greater than the height of the positioning clamp 8. The dust cover 26 is made of transparent material.

[0045] Specifically, in conventional cosmetic packaging bottle processing scenarios, plastic shavings from injection molding and ink droplets from surface printing can easily enter the connection of the conveying component 1, causing blockage of the chute 22 or jamming of the positioning clamp 8. Therefore, in this embodiment, a dust cover 26 is rotatably installed on the end of the support frame near the connecting plate 14. When the dust cover 26 rotates above the connecting plate 14, it acts as a cover over the connecting plate 14, effectively shielding contaminants and preventing plastic shavings, ink droplets, and other debris from entering the connecting plate 14. The distance between the dust cover 26 and the connecting plate 14 is greater than the height of the positioning clamp 8, ensuring that the positioning clamp 8 passes smoothly through the connecting plate 14, achieving smooth and unobstructed accurate conveying. The dust cover 26 is made of transparent material, facilitating detection by the visual recognition component 28 and manual observation.

[0046] In some preferred embodiments, the support 6 is provided with a plurality of visual recognition components 28 along the conveying direction. The visual recognition components 28 include an image processor, a laser profile sensor and an industrial camera. The image processor, laser profile sensor and industrial camera are all highly aligned with the positioning fixture 8. The image processor, laser profile sensor and industrial camera are all electrically connected to the control system 15.

[0047] Specifically, the support 6 is equipped with multiple vision recognition components 28 along the conveying direction. Each vision recognition component 28 includes an image processor, a laser contour sensor, and an industrial camera. The image processor, laser contour sensor, and industrial camera are all highly aligned with the positioning fixture 8. The image processor, laser contour sensor, and industrial camera are all electrically connected to the control system 15. Traditional equipment requires manual measurement of bottle size and setting of fixture parameters. The industrial camera captures bottle image, the laser contour sensor scans bottle size, and the image processor automatically recognizes bottle shape and size. The data is transmitted to the control system 15 to adjust the clamping parameters of the positioning fixture 8, significantly reducing recognition and adaptation time and improving automation. In addition, traditional manual inspection of packaging bottle appearance defects is inefficient and has a high rate of missed detection. The vision recognition components 28 can simultaneously detect dimensional accuracy and appearance defects, which not only helps reduce lateral positioning errors during conveying and prevents packaging bottles from shifting during transfer, but also reduces the rate of missed detection and improves inspection efficiency.

[0048] Through the above technical solutions, the intelligent processing device for cosmetic packaging bottles provided in this application includes multiple conveying components 1 and sequentially arranged injection molding mechanism 2, bottle mouth grinding mechanism 3, surface printing mechanism 4, and vacuum coating mechanism 5. Conveying components 1 are provided at the lower stations of the injection molding mechanism 2, bottle mouth grinding mechanism 3, surface printing mechanism 4, and vacuum coating mechanism 5. Adjacent conveying components 1 are connected end-to-end. In this embodiment, the injection molding mechanism 2, bottle mouth grinding mechanism 3, surface printing mechanism 4, and vacuum coating mechanism 5 are all existing mature equipment. In traditional processing devices, injection molding, grinding, printing, and coating processes often use independent equipment, requiring manual material transfer, which is not only time-consuming but also prone to errors due to manual operation. To prevent packaging bottles from shifting or getting damaged, multiple interconnected conveyor components 1 are used as conveying carriers, placed in corresponding processing station areas to achieve fully automated transfer of raw materials, forming, grinding, printing, and coating processes, shortening material transfer time. The material refers to unprocessed packaging bottle blanks. Each processing mechanism is precisely aligned with the conveyor component 1. The conveyor component 1 can adjust its conveying speed according to the rhythm of different processing steps through the control system 15, avoiding waiting or accumulation at any step and improving the overall process smoothness. Each conveyor component 1 includes a support 6, a conveyor belt 7 set at the top of the support 6 along its length, and multiple positioning clamps 8 set on the conveyor belt 7 along the conveying direction. The support 6 serves as the mounting carrier for the conveyor belt 7 and the positioning clamps 8. The bracket 6 has a protrusion 9 and a groove 10 at both ends along its length. The vertical cross-section of the groove 10 is U-shaped, with the top opening facing upwards and the side opening facing the length of the bracket 6. The opening direction of the groove 10 facilitates precise docking between adjacent conveying components 1 and effectively limits the lateral displacement of the conveying components 1. The shape of the protrusion 9 matches the shape of the groove 10, ensuring the limiting effect of adjacent conveying components 1 after docking and preventing lateral displacement of the conveying components 1. The protrusion 9 has a first positioning hole 11 in the vertical direction, and the bottom of the groove 10 has a corresponding second positioning hole 12 in the vertical direction. After the protrusion 9 and the adjacent groove 10 are fitted and engaged, they are secured by a first positioning pin 1. 3. Insert the first positioning hole 11 and the second positioning hole 12 in sequence to connect and fix them. Traditionally, when connecting the conveying components 1, they mostly adopt the planar docking method, which leads to a large lateral positioning error. After long-term operation, they are prone to loosening due to vibration. This application restricts the lateral freedom of the conveying components 1 by using the matching snap-fit ​​method of the protrusion 9 and the groove 10, and with the lateral fixation of the first positioning pin 13, so as to prevent the conveying components 1 from shifting laterally. This directly reduces the lateral positioning error in the conveying process and prevents the packaging bottle from shifting during the transfer. In addition, the guide snap-fit ​​design of the protrusion 9 and the groove 10 makes it unnecessary to repeatedly calibrate when connecting adjacent conveying components 1. When a certain group of components needs to be maintained separately, the positioning pin can be pulled out to separate them, which improves the convenience of maintenance.A connecting plate 14 is rotatably mounted on the support 6 near the end of the conveyor belt 7. When the connecting plate 14 is rotated to a horizontal position, its top surface is flush with the top surface of the conveyor belt 7. When the protrusion 9 is fitted and engaged with the adjacent groove 10, the two adjacent connecting plates 14 are seamlessly aligned. In traditional conveyor components 1, the connection points are very prone to jamming or tilting of the packaging bottles due to height differences, affecting subsequent processing and easily resulting in defective products. In this application, when the connecting plate 14 is rotated to a horizontal position, it is flush with the top surface of the conveyor belt 7, and the adjacent connecting plates 14 are seamlessly joined, ensuring that the packaging bottles move smoothly during transport. The system maintains a stable posture, preventing packaging bottles from jamming or tilting. Furthermore, when cleaning the conveyor assembly 1 or maintaining the processing mechanism, the connecting plate 14 can be flipped to free up operating space, increasing its applicability. It also includes a control system 15, composed of a PLC and a touchscreen 16. Each conveyor assembly 1 is equipped with a corresponding conveyor motor 17, which is electrically connected to the control system 15. Traditional equipment often uses integrated control; a failure in one conveyor assembly 1 requires a complete shutdown, leading to a drastic reduction in production. In this application, each conveyor assembly 1 is equipped with an independent conveyor motor 17, allowing the control system 15 to control them individually. When one group of components starts or stops, other conveyor components 1 operate normally, significantly reducing output loss due to downtime. Simultaneously, the conveying speeds of each conveyor component 1 can be coordinated to ensure multi-process collaborative processing. For example, after injection molding, the corresponding conveyor component 1 automatically accelerates to transfer the semi-finished product to the polishing station. The semi-finished product refers to the unfinished packaging bottle. The touchscreen 16 has a visual interface that displays the real-time operating status of each conveyor component 1, such as speed, temperature, and fault information, allowing staff to adjust various parameters of the conveyor component 1 according to actual processing needs. Second cylinders 18 are embedded downwards at the four corners of the support 6. The output end of the second cylinder 18 is connected to a caster wheel 19 facing downwards. Traditional conveying components 1 are mostly fixed installations, requiring three to four people to move them, resulting in low mobility. However, in this solution, the caster wheel 19 extends when the second cylinder 18 is activated, allowing one person to push the conveying component 1 to move. After installation and positioning, the second cylinder 18 is retracted, and the bracket 6 is flush with the ground to prevent the conveying component 1 from shifting due to vibration during material transport. In addition, cosmetic production workshops often need to adjust the equipment layout according to changes in orders. Based on the above structure, the conveying component 1 can move flexibly, and the processing layout can be adjusted in a timely manner to meet actual processing needs.A sleeve 20 is provided on the bracket 6 along the output direction of the second cylinder 18. The sleeve 20 is fitted around the circumferential outside of the second cylinder 18, and the bottom surface of the sleeve 20 is lower than the output surface of the second cylinder 18. The output surface refers to the end face of the piston rod of the second cylinder 18 that extends outward. When the piston rod of a traditional cylinder is in direct contact with the ground, it is easy for impurities on the ground to stick to the side wall of the piston rod, causing scratches or jamming. In this solution, the bottom surface of the sleeve 20 is lower than the output surface of the second cylinder 18, which can prevent impurities from contacting the piston rod and also guide the piston rod, preventing the piston rod from bending due to lateral forces. For example, the friction when pushing the conveying assembly 1 causes the piston rod to be subjected to lateral forces, effectively preventing the movement of the conveying assembly 1 from being obstructed due to a malfunction of the second cylinder 18. The bracket 6 of the conveying assembly 1 is made of steel. Its coefficient of thermal expansion is 11.5×10⁻⁶ / ℃. Under temperature variations of 0~40℃ in the workshop, the expansion and contraction of each meter of support 6 is approximately 0.46mm. In long-term conveying applications, gaps are prone to appear at the joints between the conveying components 1, leading to increased vibration. Therefore, a beryllium copper elastic sheet is placed between the protrusion 9 and the adjacent groove 10. The coefficient of thermal expansion of beryllium copper is 16.6×10⁻⁶ / ℃, and its elastic modulus is 130GPa. The beryllium copper elastic sheet can achieve adaptive expansion and contraction with a compensation amount of 0~0.5mm, filling the gaps caused by temperature changes and ensuring that the protrusion 9 and the groove 10 are always tightly fitted, preventing lateral displacement of the conveying component 1 and ensuring the positioning accuracy of the packaging bottle during the conveying process. In addition, the yield strength of beryllium copper is ≥1000 Nm. The beryllium copper elastic sheet absorbs the vibration energy generated during the operation of the conveyor assembly 1, reducing noise from the traditional 75dB to ≤65dB, thus improving the workshop working environment while reducing vibration. Traditional clamps are mostly fixed to the conveyor belt 7, but the conveyor belt 7 is not a rigid material that is difficult to deform, and the clamps are prone to movement and displacement due to deformation of the conveyor belt 7. Therefore, in this embodiment, the positioning clamp 8 is a pneumatic gripper, with a slider 21 connected to the bottom of the pneumatic gripper. The conveyor belt 7 has a groove 22 along the conveying direction, and the slider 21 and the groove 22 are slidably engaged. This slidable engagement structure facilitates the installation of the positioning clamp 8 while limiting its lateral displacement, improving the movement accuracy of the clamp along the conveying direction. The alignment of the packaging bottle with the processing mechanism facilitates precise processing by subsequent processing mechanisms. The slider 21 houses a first cylinder 29 for driving the pneumatic gripper to adjust its clamping size. The first cylinder 29 is electrically connected to the control system 15. Traditional clamping requires manual replacement of the gripper to accommodate different bottle sizes. This solution adjusts the clamping size of the pneumatic gripper using the first cylinder 29 to accommodate bottles of various sizes, meeting the processing needs of small-batch, multi-variety orders. The control system 15 can also automatically send commands to the first cylinder 29 based on the bottle shape dimensions collected by the vision recognition component 28 to adjust the clamping size of the pneumatic gripper, eliminating the need for manual intervention and improving automation. Furthermore, it can store multiple sets of bottle shape parameters for direct recall during subsequent processing, shortening parameter setting time.

[0049] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
