Description

Technical Field

[0001] This invention relates to the field of filling equipment, and more specifically to a viscous liquid filling machine that utilizes reset time to achieve online cleaning. Background Technology

[0002] A filling machine is the core equipment of a packaging production line, used to accurately inject liquids, pastes, powders, and other materials into containers. It is a type of machinery used in the production of daily chemical products. During operation, an empty bottle is transported to the bottom of the filling mechanism by a conveyor belt. When the sensor detection and positioning structure detects that the empty bottle has reached the bottom of the filling mechanism's outlet, the controller controls the dispensing structure of the filling mechanism to move forward synchronously with the empty bottle and controls the opening of the filling mechanism's outlet. The filling is completed during the process of the dispensing structure moving forward synchronously with the empty bottle. Filling machines offer high filling efficiency.

[0003] However, existing filling mechanisms generally still have some problems. The main problem is that when dealing with viscous materials, insufficient filling volume is easily caused by pipe blockage. This blockage is often caused by the accumulation of viscous material adhering to the wall of the feeding pipe over the years. The main solution to this problem in the existing technology is to design a flushing head in the feeding pipe connected to the discharge structure. In this way, when not filling, the inner wall of the feeding pipe can be flushed by the flushing head, which solves the problem of viscous material sticking to the wall and reduces the probability of viscous material blocking the feeding pipe.

[0004] However, we can see that this structure still has certain drawbacks. It can only be flushed after filling has stopped. This means that if flushing is not timely, some stubborn viscous material may still adhere to the inside of the pipe. Secondly, sometimes we need to meet the deadline and there is no extra time for cleaning. Therefore, the existing viscous liquid filling machine needs to be improved.

[0005] To address this issue, a viscous liquid filling machine that utilizes reset time for online cleaning is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a viscous liquid filling machine that utilizes the reset time to achieve online cleaning, thereby solving the problems in the prior art that cannot clean the inner wall of the feeding pipe in a timely manner and cannot achieve online cleaning of the inner wall of the feeding pipe during the production process.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] A viscous liquid filling machine that utilizes reset time for online cleaning includes a linear conveyor belt, an annular electric slide rail, a slider, a filling mechanism, and a raw material hopper;

[0009] The linear conveyor belt is horizontally arranged, and the annular electric slide rail includes a linear following section and a reset section. The linear following section is horizontally arranged above the linear conveyor belt, and the two ends of the linear following section and the two ends of the reset section are connected by an arc-shaped connecting section.

[0010] The slider is slidably engaged with the annular electric slide rail.

[0011] The filling mechanism includes a metering cylinder, a lifting cylinder, and a hose. The metering cylinder is fixedly connected to the slider. The discharge nozzle of the metering cylinder is set downward. When the metering cylinder moves along the straight follower section, the discharge nozzle of the metering cylinder is directly facing the straight conveyor belt. The lifting cylinder is set at the top of the metering cylinder. The cylinder rod of the lifting cylinder passes downward through the top plate of the metering cylinder and is connected to the pusher plate that is slidably set inside the metering cylinder.

[0012] The top of the outer wall of the metering cylinder is provided with a feed inlet, which is connected to the discharge end of the hose. The feed end of the hose is rotatably engaged with the bottom plate of the raw material hopper. A scraper ring is provided inside the hose. The lower surface of the scraper ring is connected to the first electric winding mechanism on the outer wall of the metering cylinder via a cable. The upper surface of the scraper ring is connected to the second electric winding mechanism at the bottom of the raw material hopper via a cable. The outer wall of the hose has a cable opening for the cable to pass through, and the diameter of the cable opening is the same as the diameter of the cable.

[0013] This solution utilizes a reset time-based online cleaning viscous liquid filling machine, a new generation of equipment designed based on a follow-up filling machine. During operation, a linear conveyor belt carries empty bottles forward. When the bottle reaches below the metering cylinder, the control system controls a slider to move forward at the same speed as the conveyor belt. The slider's movement is driven by a circular electric slide rail. Simultaneously, the metering cylinder moves forward synchronously with the empty bottle, following the slider's movement. During this synchronous forward movement, the controller controls the material in the raw material hopper to be fed into the metering cylinder through a flexible tube. Then, a lifting cylinder pushes the material from the metering cylinder into the empty bottle to complete the metering filling. Because the material in the metering cylinder is pushed into the bottle by a pusher plate, it is less likely to remain inside the metering cylinder. However, viscous material can easily remain on the inner wall of the flexible tube. To address this issue, this solution incorporates a scraper ring inside the flexible tube. After filling is completed, when the filling mechanism moves to the reset section with the slider, the first electric winding mechanism winds up the cable. During winding, the scraper ring moves downward along the hose, scraping off the viscous material adhering to the inner wall of the hose. After scraping is completed, the second electric winding mechanism winds up the cable. During winding, the scraper ring moves upward to reset, thus achieving online cleaning of the hose. This cleaning is not only timely but also does not delay the filling operation, making the whole process more efficient. In addition, water is not used for rinsing, so there is no subsequent mixing of material and water. This scraping cleaning is more thorough than rinsing cleaning. The viscous material brought out when the cable is wound will not escape from the cable opening because there is a tight fit between the cable and the cable opening. A sealing structure can also be set to block the material.

[0014] As a further preferred embodiment of the present invention, the top surface of the linear conveyor belt is provided with an empty bottle clamping mechanism, and the front end of each empty bottle clamping mechanism is provided with a signal feedback element of a photoelectric positioning sensor. The side of the linear conveyor belt is provided with a signal transmitter of a photoelectric positioning sensor that works in conjunction with the signal feedback element of the photoelectric positioning sensor.

[0015] When the signal emitted by the photoelectric positioning sensor on one side of the linear conveyor belt is captured by the signal feedback component of the photoelectric positioning sensor, it proves that the empty bottle has arrived directly below the metering cylinder. At this time, the controller controls the slider to follow the empty bottle forward, and the metering cylinder performs the filling operation, sending the liquid to be filled into the empty bottle.

[0016] As a further preferred embodiment of the present invention, the outer end face of the scraper ring is a scraper surface, the scraper surface is in close contact with the inner wall of the hose, the inner end face of the scraper ring is an arc-shaped guide surface, and the included angle between the arc-shaped guide surface and the scraper surface is less than 30°.

[0017] The inner end face of the scraper ring is an arc-shaped guide surface, which ensures that the material is not obstructed when moving in the hose and slides more smoothly. The angle between the arc-shaped guide surface and the scraper surface is less than 30°. The smaller the angle, the smoother the material slides. Moreover, a small angle is more effective than a large angle when scraping because it experiences less resistance, similar to the effect of shoveling.

[0018] As a further preferred embodiment of the present invention, the scraper ring is provided with an annular metal support frame, and the outer end of the metal support frame is provided with a spring. The outer end of the spring is connected to a support ring provided close to the outer wall of the scraper ring, and the spring is always in a compressed state.

[0019] To ensure effective scraping, the scraping surface of the scraping ring must be tightly pressed against the inner wall of the hose. To maintain this tension and extend the service life of the scraping ring, a metal support frame is installed inside the scraping ring, and a compressed spring is designed at the outer end of the metal support frame. This spring provides continuous support for the support ring, which is positioned close to the outer end face of the scraping ring. Therefore, under the action of the support ring, the outer end face of the scraping ring can always be tightly pressed against the inner wall of the hose, resulting in good scraping performance.

[0020] As a further preferred embodiment of the present invention, there are two cables connected to the first electric winding mechanism and two cables connected to the second electric winding mechanism. The first electric winding mechanism has two lower take-up grooves on both sides of the outer wall of the winding drum. The two cables connected to the first electric winding mechanism are respectively connected to the two lower take-up grooves. The other ends of the two cables connected to the first electric winding mechanism are connected to the lower surface of the scraper ring. The connection points between the two cables and the lower surface of the scraper ring are the lower tension points. The two lower tension points are symmetrically arranged on the lower surface of the scraper ring. The second electric winding mechanism has two upper take-up grooves on both sides of the outer wall of the winding drum. The two cables connected to the second electric winding mechanism are respectively connected to the two upper take-up grooves. The other ends of the two cables connected to the second electric winding mechanism are connected to the upper surface of the scraper ring. The connection points between the two cables and the upper surface of the scraper ring are the upper tension points. The two upper tension points are directly opposite the two lower tension points.

[0021] At least two cables are needed to achieve stable movement of the scraper ring. The take-up roller of the No. 1 electric take-up mechanism is driven by the No. 1 rotary motor, and the take-up roller of the No. 2 electric take-up mechanism is driven by the No. 2 rotary motor.

[0022] As a further preferred embodiment of the present invention, the cable connected to the first electric winding mechanism and the winding drum of the first electric winding mechanism are detachably connected by a threaded connection structure, and the cable connected to the second electric winding mechanism and the winding drum of the second electric winding mechanism are also detachably connected by a threaded connection structure. The cable is rotatably connected to the scraper ring. The top of the hose is threadedly connected to the first hose connector fixed to the bottom surface of the raw material hopper by a rotating threaded sleeve structure, and the bottom of the hose is threadedly connected to the second hose connector fixed to the side wall of the metering cylinder by a rotating threaded sleeve structure.

[0023] This design incorporates a scraper ring, which is connected to the No. 1 and No. 2 electric winding mechanisms via cables. While this facilitates cleaning the material inside the hose, it hinders subsequent hose replacement. To address this, threaded connections are used between the cable and the winding drums of both mechanisms. When hose replacement is needed, the cable is simply removed from the surfaces of the winding drums of both mechanisms. Then, a rotating threaded connection is used to detach the hose from the No. 2 hose connector on the side wall of the metering cylinder and the No. 1 hose connector on the bottom of the raw material hopper. This allows for complete replacement of the hose and the scraper ring. This detachable design reduces future maintenance costs.

[0024] As a further preferred embodiment of the present invention, a wear-resistant clamping sleeve is provided at the cable port.

[0025] Wear-resistant coupling sleeves can prevent cables from causing wear and damage to hoses.

[0026] As a further preferred embodiment of the present invention, a flushing port is provided above the outer wall of the hose, and a flushing pipe is connected to the flushing port. The flushing pipe is connected to a flushing pump in the flushing water tank. A material guide trough is provided below the reset section. The material guide trough is inclined, and a material collection bin is provided at the discharge end of the material guide trough.

[0027] A flushing mechanism has been added, which can be used to flush the hose during subsequent comprehensive cleaning. The material or water flowing out during cleaning enters the guide trough and then flows into the receiving collection bin for collection and reuse.

[0028] As a further preferred embodiment of the present invention, the bottom surface of the pusher plate is provided with a downwardly protruding pusher that is adapted to the metering cylinder outlet at the position opposite to the metering cylinder outlet.

[0029] The metering cylinder outlet is also one of the causes of blockage. Therefore, this solution sets a pushing protrusion on the bottom surface of the pushing plate. When the pushing plate reaches the bottom of the metering cylinder, the pushing protrusion enters the metering cylinder outlet to clean the metering cylinder outlet.

[0030] As a further preferred embodiment of the present invention, the raw material silo is provided with a plurality of metering pumps, the number of metering pumps being the same as the number of metering cylinders, the outlet of the metering pumps being connected to the feed inlet of the hose, and the silo wall of the raw material silo being provided with an electric heating plate.

[0031] In this solution, solenoid valves are installed at each key node, such as the discharge port of the raw material silo and the discharge nozzle of the metering cylinder. The specific configuration location can refer to the conventional design in this field. The silo wall is equipped with an electric heating plate to maintain the temperature of the raw material silo, maintain the fluidity of viscous materials in cold environments, and reduce the problem of wall adhesion.

[0032] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0033] This solution utilizes a reset time-based online cleaning viscous liquid filling machine, a new generation of equipment designed based on a follow-up filling machine. During operation, a linear conveyor belt carries empty bottles forward. When the bottle reaches below the metering cylinder, the control system controls a slider to move forward at the same speed as the conveyor belt. The slider's movement is driven by a circular electric slide rail. Simultaneously, the metering cylinder moves forward synchronously with the empty bottle, following the slider's movement. During this synchronous forward movement, the controller controls the material in the raw material hopper to be fed into the metering cylinder through a flexible tube. Then, a lifting cylinder pushes the material from the metering cylinder into the empty bottle to complete the metering filling. Because the material in the metering cylinder is pushed into the bottle by a pusher plate, material is less likely to remain inside the metering cylinder; however, residue can easily remain on the inner wall of the flexible tube. To address the issue of viscous materials, this solution incorporates a scraper ring inside the hose. After filling, as the filling mechanism moves to the reset section with the slider, the first electric winding mechanism rewinds the cable. During this winding, the scraper ring moves downwards along the hose, scraping off the viscous material adhering to the inner wall. Once scraping is complete, the second electric winding mechanism rewinds the cable, causing the scraper ring to move upwards and reset. This allows for online cleaning of the hose, which is timely and doesn't interrupt the filling process, making the entire process more efficient. Furthermore, since water is not used for rinsing, there is no risk of material mixing with water. This scraping cleaning method is more thorough than rinsing. Attached Figure Description

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, so as to provide a better understanding of the concept of the present invention, the technical problem solved, the technical features constituting the technical solution, and the technical effects brought about. Specific Implementation Example 1:

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a viscous liquid filling machine that utilizes reset time to achieve online cleaning includes a linear conveyor belt 1, an annular electric slide rail 2, a slider 3, a filling mechanism, and a raw material bin 4.

[0043] The linear conveyor belt 1 is horizontally arranged, and the annular electric slide rail 2 includes a linear following section 21 and a reset section 22. The linear following section 21 is horizontally arranged above the linear conveyor belt 1, and the two ends of the linear following section 21 and the two ends of the reset section 22 are connected by an arc-shaped connecting section.

[0044] The slider 3 is slidably engaged with the annular electric slide rail 2;

[0045] The filling mechanism includes a metering cylinder 5, a lifting cylinder 6, and a hose 7. The metering cylinder 5 is fixedly connected to the slider 3. The discharge nozzle of the metering cylinder 5 is set downward. When the metering cylinder 5 moves along the straight following section 21, the discharge nozzle of the metering cylinder 5 is directly facing the straight conveyor belt 1. The lifting cylinder 6 is set at the top of the metering cylinder 5. The cylinder rod of the lifting cylinder 6 passes downward through the top plate of the metering cylinder 5 and is connected to the push plate 8 that is slidably set inside the metering cylinder 5.

[0046] The top of the outer wall of the metering cylinder 5 is provided with a feed inlet, which is connected to the discharge end of the hose 7. The feed end of the hose 7 is rotatably engaged with the bottom plate of the raw material silo 4. The hose 7 is provided with a scraper ring 9. The lower surface of the scraper ring 9 is connected to the first electric winding mechanism 11 on the outer wall of the metering cylinder 5 via a cable 10. The upper surface of the scraper ring 9 is connected to the second electric winding mechanism 12 at the bottom of the raw material silo 4 via a cable 10. The outer wall of the hose 7 is provided with a cable opening for the cable 10 to pass through. The diameter of the cable opening is the same as the diameter of the cable 10.

[0047] This solution utilizes a reset time-based online cleaning system for viscous liquid filling machines, a new generation of equipment designed based on follow-up filling machines. During operation, a linear conveyor belt carries empty bottles forward. When the bottle reaches below the metering cylinder, the control system controls a slider to move forward at the same speed as the linear conveyor belt. The slider's movement is driven by a circular electric slide rail. Simultaneously, the metering cylinder moves forward synchronously with the empty bottle, following the slider's movement. During this synchronous forward movement, the controller controls the material in the raw material hopper to be fed into the metering cylinder through a flexible tube. Then, a lifting cylinder pushes the material from the metering cylinder into the empty bottle to complete the metering filling. Because the material in the metering cylinder is pushed into the empty bottle by a pusher plate, it is less likely to remain inside the metering cylinder. However, viscous material easily remains on the inner wall of the flexible tube. To address this issue, this solution incorporates a scraper ring inside the flexible tube. After filling, when the filling mechanism moves to the reset section with the slider, a first-stage electric winding mechanism winds up the cable. During cable winding, the scraper ring moves downwards along the flexible tube, removing any viscous material adhering to the inner wall of the flexible tube. The material is scraped off, and after scraping is complete, the second electric winding mechanism is controlled to wind up the cable. When the second electric winding mechanism winds up the cable, the scraping ring moves upward to reset, thus achieving online cleaning of the hose. This cleaning is not only timely but also does not delay the filling operation, making the whole process more efficient. In addition, water is not used for rinsing, so there is no subsequent mixing of material and water. This scraping cleaning is more thorough than rinsing cleaning. By setting a sealing structure, the viscous material carried on the surface of the cable will not escape from the cable opening when it is wound up. The specific sealing structure can be a rubber wire guide ring or a stuffing box wire seal set at the cable opening. The hose will bend during movement, but its total length remains unchanged. The scraping ring is in tight contact with the inner wall of the hose. Relying on the friction between the scraping ring and the inner wall of the hose, the position of the scraping ring hardly changes. Therefore, when not scraping, the bending of the hose will only cause the cable to bend, without the problem of the cable being taut. In addition, in order to accommodate the cable tautness caused by the bending of the hose during the scraping process, high tensile strength cable can be used here. Specific Implementation Example 2:

[0049] This embodiment further describes the linear conveyor belt 1 based on specific embodiment 1. The top surface of the linear conveyor belt 1 is provided with an empty bottle clamping mechanism 13. Each empty bottle clamping mechanism 13 has a signal feedback element of a photoelectric positioning sensor at its front end. The side of the linear conveyor belt 1 is provided with a signal transmitter of a photoelectric positioning sensor that works in conjunction with the signal feedback element of the photoelectric positioning sensor.

[0050] When the signal emitted by the photoelectric positioning sensor on one side of the linear conveyor belt is captured by the signal feedback component of the photoelectric positioning sensor, it proves that the empty bottle has arrived directly below the metering cylinder. At this time, the controller controls the slider to follow the empty bottle forward, and the metering cylinder performs the filling operation, sending the liquid to be filled into the empty bottle. Specific Implementation Example 3:

[0052] This embodiment further describes the scraper ring 9 based on specific embodiment 1. The outer end face of the scraper ring 9 is the scraping surface, which is in close contact with the inner wall of the hose 7. The inner end face of the scraper ring 9 is an arc-shaped guiding surface, and the included angle between the arc-shaped guiding surface and the scraping surface is less than 30°.

[0053] The inner end face of the scraper ring is an arc-shaped guide surface, which ensures that the material is not obstructed when moving in the hose and slides more smoothly. The angle between the arc-shaped guide surface and the scraper surface is less than 30°. The smaller the angle, the smoother the material slides. Moreover, a small angle is more effective than a large angle when scraping because it experiences less resistance, similar to the effect of shoveling. Specific Implementation Example 4:

[0055] This embodiment further describes the scraper ring 9 based on specific embodiment 3. The scraper ring 9 is provided with an annular metal support frame 14. The outer end of the metal support frame 14 is provided with a spring 15. The outer end of the spring 15 is connected to a support ring 16 provided close to the outer wall of the scraper ring 9. The spring 15 is always in a compressed state.

[0056] To ensure effective scraping, the scraping surface of the scraping ring must be tightly pressed against the inner wall of the hose. To maintain this tension and extend the service life of the scraping ring, a metal support frame is installed inside the scraping ring, and a compressed spring is designed at the outer end of the metal support frame. This spring provides continuous support for the support ring, which is positioned close to the outer end face of the scraping ring. Therefore, under the action of the support ring, the outer end face of the scraping ring can always be tightly pressed against the inner wall of the hose, resulting in good scraping performance. Specific Implementation Example 5:

[0058] This embodiment further describes the cables 10 based on specific embodiment 1. There are two cables 10 connected to the first electric winding mechanism 11 and two cables 10 connected to the second electric winding mechanism 12. The outer wall of the winding drum of the first electric winding mechanism 11 has two lower winding grooves on both sides. The two cables 10 connected to the first electric winding mechanism 11 are respectively connected to the two lower winding grooves. The other ends of the two cables 10 connected to the first electric winding mechanism 11 are connected to the lower surface of the scraper ring 9. The connection point between 10 and the lower surface of the scraper ring 9 is the lower tension point, and the two lower tension points are symmetrically arranged on the lower surface of the scraper ring 9; the outer wall of the winding drum of the second electric winding mechanism 12 is provided with two upper winding grooves on both sides, and two cables 10 connected to the second electric winding mechanism 12 are respectively connected to the two upper winding grooves. The other end of the two cables 10 connected to the second electric winding mechanism 12 is connected to the upper surface of the scraper ring 9, and the connection point between the two cables 10 and the upper surface of the scraper ring 9 is the upper tension point, and the two upper tension points are set opposite to the two lower tension points.

[0059] At least two cables are needed to achieve stable movement of the scraper ring. The take-up roller of the No. 1 electric take-up mechanism is driven by the No. 1 rotary motor, and the take-up roller of the No. 2 electric take-up mechanism is driven by the No. 2 rotary motor. Specific Implementation Example 6:

[0061] This embodiment further describes the cable 10 based on specific embodiment 5. The cable 10 connected to the first electric winding mechanism 11 and the winding drum of the first electric winding mechanism 11 are detachably connected by a threaded connection structure. The cable 10 connected to the second electric winding mechanism 12 and the winding drum of the second electric winding mechanism 12 are also detachably connected by a threaded connection structure. The cable 10 is rotatably connected to the scraper ring 9. The top of the hose 7 is threadedly connected to the first hose connector fixed on the bottom surface of the raw material hopper 4 through a rotating threaded sleeve structure 71. The bottom of the hose 7 is threadedly connected to the second hose connector fixed on the side wall of the metering cylinder 5 through a rotating threaded sleeve structure 71.

[0062] This design incorporates a scraper ring, which is connected to the No. 1 and No. 2 electric winding mechanisms via cables. While this facilitates cleaning the material inside the hose, it hinders subsequent hose replacement. To address this, threaded connections are used between the cable and the winding drums of both mechanisms. When hose replacement is needed, the cable is simply removed from the surfaces of the winding drums of both mechanisms. Then, a rotating threaded connection is used to detach the hose from the No. 2 hose connector on the side wall of the metering cylinder and the No. 1 hose connector on the bottom of the raw material hopper. This allows for complete replacement of the hose and the scraper ring. This detachable design reduces future maintenance costs. Specific Implementation Example 7:

[0064] This embodiment further describes the cable port based on specific embodiment 1, wherein the cable port is provided with a wear-resistant clip 18.

[0065] Wear-resistant coupling sleeves can prevent cables from causing wear and damage to hoses. Specific Implementation Example 8:

[0067] This embodiment further describes the hose 7 based on specific embodiment 1. The hose 7 is also provided with a flushing port on the upper part of its outer wall. The flushing port is connected to a flushing pipe, which is connected to a flushing pump in the flushing water tank. A guide trough 17 is provided below the reset section 22. The guide trough 17 is inclined and a material collection bin is provided at the discharge end of the guide trough 17.

[0068] A flushing mechanism has been added, which can be used to flush the hose during subsequent comprehensive cleaning. The material or water flowing out during cleaning enters the guide trough and then flows into the receiving collection bin for collection and reuse. Specific Implementation Example 9:

[0070] This embodiment further describes the pusher plate 8 based on specific embodiment 1. The bottom surface of the pusher plate 8 is provided with a downward protruding pusher 81 that is adapted to the discharge nozzle of the metering cylinder 5.

[0071] The metering cylinder outlet is also one of the causes of blockage. Therefore, this solution sets a pushing protrusion on the bottom surface of the pushing plate. When the pushing plate reaches the bottom of the metering cylinder, the pushing protrusion enters the metering cylinder outlet to clean the metering cylinder outlet. Specific Implementation Example 10:

[0073] This embodiment further describes the raw material silo 4 based on specific embodiment 1. The raw material silo 4 is equipped with several metering pumps, the number of which is the same as the number of metering cylinders 5. The outlet of the metering pump is connected to the inlet end of the hose 7. The silo wall of the raw material silo 4 is equipped with an electric heating plate.

[0074] The metering pump is installed in the raw material silo, and its outlet is connected to a rigid connector on the top surface of the silo bottom plate via a pipe. This rigid connector is connected to the discharge port at the bottom of the raw material silo, and the bottom surface of the discharge port is connected to the No. 1 flexible hose connector. In this solution, solenoid valves are installed at each key node, such as the discharge port of the raw material silo and the discharge nozzle of the metering cylinder. The specific configuration positions can refer to the conventional design in this field.
