Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery, in particular to a barrel-shaped structure veneer paper process and a barrel-shaped structure box veneer paper production line. Background Art

[0002] The existing production process for barrel-shaped structures generally involves four main steps: gluing the face paper, aligning the three sides of the gluing face paper with three sides of the grayboard, and then gluing them together in a top-to-bottom relationship, keeping the V-grooves of the grayboard aligned with the long indentations of the face paper; pre-folding the exposed edges of the three corresponding sides, and then folding the box. After the box is formed, the unattached side of the face paper is scraped onto the remaining surface of the grayboard. In other words, the conventional setup is to first glue the face paper and grayboard together to form a bonded body, which is then folded to form a body with five folded sides, with the face paper covering the sides and bottom of the barrel.

[0003] While some barrel-shaped boxes share a barrel-shaped body, the tissue paper is not a single sheet. Instead, it is split into a short sheet for the barrel body and a long sheet connecting the box and the barrel body. Therefore, production equipment developed for traditional barrel-shaped boxes is no longer suitable. The new production process requires grayboard forming before the tissue paper is attached. Furthermore, the barrel-shaped structure itself has unconventional shapes, so specialized equipment development is required for these specialized barrel-shaped boxes. Summary of the Invention

[0004] The main purpose of the present invention is to propose a barrel-shaped structure veneer paper process, aiming to solve the demand for veneer paper on the outer surface of the barrel-shaped structure that has been formed by gray board.

[0005] Another object of the present invention is to provide a barrel-shaped structural box veneer paper production line, which aims to solve the demand for veneer paper on the outer surface of a barrel-shaped structural box having a barrel-shaped structural box.

[0006] The present invention provides a barrel-shaped box comprising a barrel lid, a barrel body, and a plurality of tissue papers. Due to the unique structural characteristics of this barrel-shaped structure, the barrel lid and barrel body must first be separately formed from grayboard, and then a single sheet of tissue paper, or a combination of tissue paper, must be attached to the corresponding sides of the barrel lid and barrel body. Corresponding to the barrel-shaped structure formed from grayboard, the barrel-shaped structure is composed of a surrounding grayboard and a cover. The tissue paper required for the barrel-shaped structure is divided into long and short tissue papers according to their functional surfaces and functions. The long tissue paper serves to connect the barrel body and the barrel lid.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0064] The production process for a barrel-shaped structure generally involves four main steps: gluing the face paper, aligning the three sides of the gluing face paper with three sides of the grayboard, and gluing them together in a top-to-bottom relationship, keeping the V-grooves of the grayboard aligned with the long indentations of the face paper; pre-folding the exposed edges of the three corresponding sides, and then folding the box. After the box is formed, the unattached side of the face paper is scraped onto the remaining surface of the grayboard. In other words, the conventional setup is to first glue the face paper and grayboard, then fold it. This is mainly applicable to the basic barrel body, which has a grayboard with five folded sides and a full sheet of face paper covering the sides and bottom of the barrel body.

[0065] Please refer to Figure 1 The present invention provides a barrel-shaped structure, which is composed of a barrel cover 202 and a barrel body 201. Due to its special structural characteristics, the barrel-shaped structure needs to be formed by forming the barrel cover and the barrel body gray board separately, and then the corresponding side surfaces of the barrel cover 202 and / or the barrel body 201 are pasted with surface paper. In view of this, the present invention provides a barrel-shaped structure veneer paper process and a barrel-shaped structure box veneer paper production line. Figures 2 to 4This is a flow chart of the barrel-shaped structure veneer paper process provided by the present invention. Figures 5 to 7 This is an embodiment of the barrel-shaped facial tissue laminating device provided by the present invention. Figures 8 to 14 This is another embodiment of the bucket-shaped facial tissue laminating device provided by the present invention.

[0066] Please refer to Figures 2 to 4 In the barrel-shaped veneer paper process, a feeding station 1a, a gluing station 1b, a folding station 1c, and a discharging station 1d are provided. At least one inner mold 22 is provided and circulated between the four stations. The process operation of each station is as follows:

[0067] At the feeding station 1a, the barrel-shaped incoming material is sleeved on the outer surface of the inner mold 22;

[0068] The glued facial tissue paper waits at the bonding station 1b, and the barrel-shaped structure carried by the inner mold 22 is bonded to the facial tissue paper to obtain a bonded body;

[0069] At the folding station 1c, the folding of the face paper in the adhesive body is completed;

[0070] At the discharging station 1d, the bonded body after folding is removed from the inner mold 22.

[0071] In the technical solution of the present invention, initially, the inner mold 11 is in the feeding station 1a, and the incoming material of the barrel-shaped structure is sleeved on the inner mold 22. As the inner mold 22 moves, the barrel-shaped structure is driven to be transferred to the bonding station 1b. At this time, the gluing facial tissue is waiting at the bonding station 1b. The inner mold 22 is moved so that one side of the barrel-shaped structure is bonded to the pre-glued facial tissue to obtain a bonded body. At this time, the facial tissue has a partial residual edge exposed at the outer edge of the barrel-shaped structure. The inner mold 22 is continued to be moved to transfer the bonded body to the folding station 1c to fold the exposed residual edge of the facial tissue. Finally, it is moved to the discharging station 1d to separate the bonded body from the inner mold 22 to complete the facial tissue bonding process on the corresponding side of the barrel-shaped structure. The loading, veneering, folding and stripping of the barrel-shaped structure are completed in sequence through the turnover between multiple stations, thereby improving the convenience of production and processing and facilitating mass production.

[0072] Furthermore, at the bonding station, while the inner mold 22 drives the barrel-shaped structure to adhere to the corresponding facial tissue, two oppositely disposed exposed edges 300a of the facial tissue are folded to adhere to the sidewalls. At the folding station, the remaining exposed edges 300a of the facial tissue in the bonded body are folded. Specifically, the exposed edges 300a of the facial tissue are folded twice, one at the bonding station 1b and the other at the folding station 1c. The first folding is performed on the exposed edges 300a along the width of the barrel-shaped structure, and the second folding is performed on the exposed edges 300a along the barrel opening and bottom of the barrel. This facilitates the layout of the folding equipment and avoids problems such as crowded folding equipment layout, interference, and long pauses between equipment operations caused by single-station folding.

[0073] It should be noted that because the bottom and sides of the barrel structure are perpendicular to each other, the first folding can be completed in one step: the scraper or brush roller moves upward to directly scrape the exposed edge 300a of the facial tissue to a vertical position. The second folding, corresponding to the barrel opening, requires at least two steps: first scraping the exposed edge 300a of the facial tissue to a vertical position, and then scraping the exposed edge 300a to a horizontal position to align with the inner wall of the barrel opening.

[0074] To facilitate equipment layout at each workstation, each station is arranged in a cross-shaped configuration. The inner mold 22's trajectory forms a circular projection on the plane where the station resides, with one end of the inner mold 22 extending tangentially to this circular trajectory. This facilitates intelligent control of the inner mold 22's rotation angle, with each 90° rotation switching between workstations. Furthermore, this arrangement ensures ample space at each workstation, further concentrating equipment and conveyor components within a specific area.

[0075] The present invention also proposes a barrel-shaped structure box veneer paper production line for making Figure 1 The barrel-shaped structure box shown in the figure has two veneer paper segment production lines arranged as follows:

[0076] like Figure 2 First, a device provided by the present invention is arranged to process the barrel body 201, wherein the side where the tip of the barrel body 201 is facing downward, and the object facial tissue 300 to be pasted with it is a shorter facial tissue. After processing at four stations, the output barrel body 201 is turned over manually or by a flipping device to turn the side where the tip is facing upward, so that the other unpasted side faces downward, as the input material for the next process.

[0077] like Figure 3Another device provided by the present invention is then deployed to simultaneously process the barrel body 201 and lid 202. The tissue paper 300 to be attached is now a long sheet of tissue paper, used to connect the barrel body 201 and lid 202. The barrel body material and the lid 202 opening from the previous process are aligned and fed into the first station of this device. At the second station, both are attached to the long tissue paper material. All required folding is completed at the third station, and finally, they are demolded together at the fourth station. The product then enters the next production process for further processing.

[0078] Two veneer paper devices were designed in this production line using the same inventive concept, which successively completed the pasting of short and long veneer paper for this type of box. This not only met the process requirements, but also improved the degree of automation of the entire line for this type of box, reducing development costs and mechanical costs of the device.

[0079] The barrel-shaped structural box includes a partially connected barrel body 201 and a barrel cover 202, one side of the barrel body 201 is set at a sharp angle at the barrel mouth, and the corresponding side of the barrel cover 202 is provided with a V-shaped groove; the barrel-shaped structural box veneer paper production line uses the above-mentioned barrel-shaped structural veneer paper process to perform facial paper lamination, wherein the inner mold is a combined inner mold, including a first inner mold 221 and a second inner mold 222, and the two inner molds are synchronously transferred between four workstations, one of the inner molds matches the barrel body 201 after flipping, and the other inner mold matches the barrel cover 202; the two inner molds synchronously carry the barrel body 201 and the barrel cover 202 to laminate the long facial paper.

[0080] Specifically, in one embodiment, each inner mold 22 includes a first inner mold 221, a connecting plate 223, and a second inner mold 222, which are connected in sequence. The first inner mold 221 and the second inner mold 222 are located at opposite ends of the connecting plate 223. The first inner mold 221 is used to fit the inner wall surface of the barrel body 201, and the second inner mold 222 is used to fit the inner wall surface of the lid 202. The connecting plate 223 is connected to the first inner mold 221 and the second inner mold 222 to ensure synchronous transportation of the two, while not obstructing the installation of the lid 202 and the barrel body 201.

[0081] The following is a preferred implementation structure for realizing the process.

[0082] Please refer to Figure 5 、 Figure 8 、 Figure 9The barrel-type facial tissue laminating device 100 includes a machine base 1, a turntable mechanism 2, a folding assembly 4 and a sticker assembly 3. The machine base 1 has a feeding station 1a, a bonding station 1b, a folding station 1c and a discharging station 1d arranged at intervals along the circumferential direction; the turntable mechanism 2 has a movable seat 21 and at least one inner mold 22 located on the movable seat 21, and the movable seat 21 can be rotated along an axis extending in the up and down directions to drive the inner mold 22 to switch between the various stations; the sticker assembly 3 is located in the bonding station 1b, and is used to cooperate with the inner mold 22 to laminat the facial tissue to the surface of the barrel-type structure; the folding assembly 4 is used to cooperate with the inner mold 22 to laminat the exposed edge 300a of the facial tissue on the circumferential side to the barrel body 201. The movable seat 21 rotates to drive the inner mold 22 to rotate, so that the inner mold 22 passes through four stations in sequence to complete the facial tissue lamination. At the feeding station 1a, the inner mold 22 absorbs the barrel-shaped structure so that it is sleeved on the outer surface of the inner mold 22. It rotates to the bonding station 1b to attach the facial tissue, and continues to rotate to the folding station 1c. The exposed edge 300a of the facial tissue is trimmed by the folding assembly 4 so that the edge is attached to the barrel body 201. Finally, it moves to the discharging station 1d to complete the discharging of the barrel-shaped structure with the facial tissue attached. The feeding station 1a, the bonding station 1b, the folding station 1c, and the discharging station 1d are distributed along the circumference. The way the inner mold 22 and the barrel-shaped structure cooperate is highly flexible and has a wide range of applications, which is convenient for mass production and has high production efficiency.

[0083] The present invention does not limit the rotational driving method of the movable seat 21, which may be driven by a motor directly, with a motor belt, with a motor sprocket, etc., which will not be described in detail here.

[0084] In order to facilitate the loading of paper on the bonding station 1b, please refer to Figure 6 and Figure 11 In one embodiment of the present invention, the sticker assembly 3 includes a first conveyor belt 31, the side of which is positioned directly opposite the gluing station 1b. The first conveyor belt 31 is used to transport partially glued tissue paper to the gluing station 1b. The first conveyor belt 31 transports tissue paper from back to front. A positioning and pressure-maintaining structure 42 is provided at the front end of the first conveyor belt 31 to correct the tissue paper's position, ensuring it remains in the gluing station 1b. Upon entering the gluing station 1b, the inner mold 22 simply drops downward, eliminating the need for separate position adjustment of the inner mold 22.

[0085] Specifically, a push-angle positioning structure is provided on the first conveyor belt 31. It comprises four movable claws corresponding to the four right angles of the facial paper. These claws are movable so as not to obstruct the incoming facial paper. Once the facial paper is in place, the movable claws extend to push the top corners of the facial paper for positioning. Furthermore, the width of the first conveyor belt 31 should be smaller than the width of the facial paper. This configuration facilitates the pre-folding process. Of course, those skilled in the art, based on their experience, can also provide a push plate assembly to position the facial paper along its four edges, equivalent to the push-angle positioning structure.

[0086] Further, in one embodiment, please refer to Figures 6 and 7 as well as Figures 10 and 11 The hemming assembly 4 includes a first hemming group located at the gluing station 1b and a second hemming group located at the hemming station 1c. Each of the first and second hemming groups includes two opposing scrapers or brush rollers that can move vertically and sequentially hemming the exposed margins 300a on the circumference of the face paper. After the barrel-shaped structure at the gluing station 1a has completed the face paper lamination operation, the two scrapers or brush rollers located on either side of the inner mold 22 in the width direction move upward, scraping the exposed margins 300a on the corresponding sides until they align with the vertical sides of the barrel-shaped structure. The inner mold 22 then moves the face paper and barrel-shaped structure into the hemming station 1c, where the remaining exposed margins 300a are then hemmed. This splits the hemming operation between the two stations, facilitating the layout of the first and second hemming groups and preventing interference from occurring due to excessive equipment at a single station.

[0087] The present invention does not limit the driving method of the scraper or brush roller, which can be an electric push rod, a cylinder, etc., as long as it can achieve up and down movement, which will not be described in detail here.

[0088] In another embodiment, the scraper or brush roller is set to protrude from the first conveyor belt 31 in a natural state and remains stationary during the entire process. As the inner mold 22 is pressed downward, the exposed residual edge is set to contact the scraper or brush roller, and the folding action is naturally completed.

[0089] Furthermore, the feeding station 1a, the bonding station 1b, the hemming station 1c, and the discharging station 1d are arranged in a cross-shaped configuration; the projection of the inner mold 22's motion trajectory onto the plane where the stations are located is circular, with one end of the inner mold 22 extending tangentially to this circular motion trajectory. The circular motion trajectory of the inner mold 22 and the cross-shaped configuration of the four stations facilitate intelligent control of the single rotation angle of the inner mold 22, with each 90° rotation switching the stations. Different orientations of the inner mold 22 result in different layouts of the corresponding devices at each station. If the extension direction of the inner mold 22 is set to be radial along the circular trajectory, the production lines on each station need to be arranged along the corresponding direction, and the production lines will present a cross shape that diverges to the circumference with the turntable structure 2 as the center, which occupies a large space; and when the barrel-shaped structure is a structure in which the barrel body 201 and the barrel cover 202 are fastened together, the docking loading line at the loading station 1a is difficult to arrange, and interference problems will occur when the barrel body material and the barrel cover material are simultaneously inserted into the mold. Therefore, when the inner mold 22 is along the tangential direction, the corresponding devices on each station can be arranged in staggered directions, respectively, which provides more sufficient space for the layout of mechanical equipment and avoids interference.

[0090] When one of the side surfaces of the barrel-shaped structure is provided with a sharp angle at the barrel mouth, the facial tissue is provided with two exposed margins 300a located on the same side and provided at an angle; for this structure, in one embodiment, please refer to Figure 7 The folding assembly 4 includes a first scraping structure located at the folding station. The first scraping structure includes two first scraping plates 411. The two first scraping plates 411 are arranged at an angle to each other to scrape the corresponding two exposed edges 300a on the tissue paper until they are in contact with the wall surface at the barrel mouth. Specifically, the two first scraping plates 411 first move upward together to push the two exposed edges 300a to be vertical, and then the two first scraping plates 411 move toward the barrel mouth of the barrel structure simultaneously or successively, thereby scraping the corresponding two exposed edges 300a in sequence. After the two exposed edges 300a are partially overlapped after the bonding is completed. The translation and up and down movement of the corresponding two first scraping plates 411 can be driven by structures such as a cylinder, an electric push rod, and a ball screw.

[0091] Correspondingly, at the folding station 1c, the facial tissue has two exposed edges 300a corresponding to the barrel mouth and the barrel bottom to be folded. The exposed edge 300a at the barrel mouth is folded by the first shoveling structure, and at the barrel bottom, the folding can be performed by a scraper or a brush roller, or the scraper or brush roller can be set to remain fixed, and the scraping action is completed due to the natural resistance as the adhesive falls, or the scraper or brush roller is set to have an upward and downward movable stroke. When the first shoveling structure is working, the scraper or brush roller moves upward and simultaneously performs the folding action of the exposed edge 300a at the barrel bottom.

[0092] When a V-shaped groove is provided on one side of the barrel structure corresponding to the barrel mouth, the facial tissue is provided with two exposed margins 300a located on the same side and arranged at an angle; for this structure, in one embodiment, please refer to Figure 10 The hemming assembly includes a second scraping structure located at the hemming station. The second scraping structure includes a second scraping plate 431. One end of the second scraping plate 431 is configured at a sharp angle corresponding to the V-shaped groove, and is used to simultaneously scrape the two corresponding exposed edges 300a on the tissue paper until they are in contact with the wall surface inside the barrel mouth. Specifically, the second scraping plate 431 first moves upward, pushing the two corresponding exposed edges 300a to a vertical position, and then stops moving horizontally toward the barrel mouth. The tip of the second scraping plate 431 can simultaneously scrape the two exposed edges 300a flat, thereby completing the contact. The corresponding translation and up and down movement of the second scraping plate 431 can be driven by a cylinder, an electric push rod, a ball screw, or other structures.

[0093] Correspondingly, at the folding station 1c, the facial tissue has two exposed edges 300a corresponding to the barrel mouth and the barrel bottom to be folded. The exposed edge 300a at the barrel mouth is folded by the second shoveling structure, and at the barrel bottom, it can be folded by a scraper or a brush roller. The scraper or brush roller can be set to remain fixed and complete the shoveling action due to the natural resistance as the adhesive falls, or the scraper or brush roller can be set to have an upward and downward movable stroke. When the second shoveling structure is working, the scraper or brush roller moves upward and simultaneously performs the folding action of the exposed edge 300a at the barrel bottom.

[0094] To achieve the up and down movement of the inner mold 22, the barrel-shaped tissue laminating device further includes a lifting structure 8. This lifting structure 8 is connected to the inner mold 22 and is mounted on the movable seat 21 to drive the inner mold 22 to move up and down relative to the turntable mechanism 2. The lifting structure 8 cooperates with the movable seat 21 to enable the inner mold 22 to switch between workstations. During the transition between workstations, the inner mold 22 is driven downward into the corresponding workstation and lifted upward to transfer to the next workstation. The provision of the lifting structure 8 allows the inner mold 22 to adapt in height during the transition between workstations, preventing interference with other mechanical structures during rotation.

[0095] It should be noted that the present invention does not limit the specific form of the lifting structure 8. The lifting structure 8 can be driven by a cylinder or a screw structure can be applied, which will not be described in detail here.

[0096] In this embodiment, four inner molds 22 are provided and distributed circumferentially on the movable seat 21; correspondingly, four lifting structures 8 are provided. The inner molds 22 at different workstations can be controlled to drive the barrel-shaped structure to perform different actions, thereby improving processing efficiency and facilitating mass production.

[0097] Please refer to Figure 11 In one embodiment, the inner mold 22 is a combined inner mold, including a first inner mold 221 and a second inner mold 222. The two inner molds are synchronously transferred between four workstations, one of which matches one barrel-shaped structure, and the other matches another barrel-shaped structure. The design of the combined inner mold allows the device to paste long tissue paper on a complex box consisting of two barrel-shaped structures. The first inner mold 221 and the second inner mold 222 move synchronously so that the corresponding surface of the long tissue paper is simultaneously attached to the two barrel-shaped structures. It should be noted that in the combined inner mold, the first inner mold 221 and the second inner mold 222 can be spaced apart and driven synchronously by a cylinder, or two cylinders can drive the first inner mold 221 and the second inner mold 222 separately. They can be assembled and spliced ​​to each other, and can be disassembled separately and used separately after disassembly. They can also be combined into an inseparable whole by direct or indirect means, and there is no limitation here.

[0098] To facilitate the pressure holding in folding station 1c, please refer to Figure 7 or Figure 13 The hemming assembly 4 also includes multiple positioning and pressure-maintaining structures 42, spaced apart from the corresponding hemming structures. Each positioning and pressure-maintaining structure 42 comprises a first base 421 and two first push plates 422. The first base 421 is mounted on the base 1. The two first push plates 422 are movably mounted on the first base 421. The opposing sides of the two first push plates 422 are used to clamp and secure the corresponding side walls of the barrel structure. This ensures the stability of the bottom and opening hemming, ensuring the hemming effect. When laminating long tissue paper to the barrel body 201 and lid 202, positioning and pressure-maintaining structures 42 are required at the corresponding locations on the barrel body 201 and lid 202. This prevents wrinkles in the section of tissue paper located between the barrel body 201 and lid 202. It should be noted that the first push plates 422 can be driven by a cylinder or a screw, which will not be explained in detail here.

[0099] After the paper is pasted and folded, in order to realize the separation action at the discharge station 1d, please refer to Figure 12The barrel-shaped structure tissue laminating device 100 further includes at least one demolding assembly 5, which includes a fixed seat and two clamping plates 51 located on the fixed seat. The two clamping plates 51 have a movable stroke that approaches each other. The opposite sides of the two clamping plates 51 are used to jointly clamp the corresponding sides of the barrel-shaped structure. The fixed seat can be movably mounted to the machine base 1 to drive the barrel-shaped structure to separate from the inner mold 22. Specifically, the two clamping plates 51 on the left clamp together to ensure stability. As the movable seat 21 moves to the right, the two clamping plates 51 drive the bonded body and the inner mold 22 to move relative to each other, gradually completing the separation action. After separation, the inner mold 22 continues to be lifted and rotated to the loading station for processing the next barrel-shaped structure.

[0100] It should be noted that the clamping plate 51 can be driven by a cylinder or a screw, which will not be described in detail here.

[0101] In order to facilitate the connection of the subsequent process, please refer to Figure 14 The barrel-type tissue laminating device 100 further includes a suction cup transfer mechanism 6, located on the side of the discharge station 1d away from the turntable mechanism 2. The suction cup transfer mechanism 6 includes suction cups for adsorbing the barrel body 201 and lid 202 located at the discharge station 1d and moving them out. This facilitates the transfer of the bonded body to subsequent processing steps. In this structure, the suction cups are located above the machine base 1, creating a compact layout and facilitating transfer.

[0102] It should be noted that when the barrel body 201 and the barrel cover 202 are affixed with a long tissue, the tissue section located between the barrel body 201 and the barrel cover 202 is not temporarily folded in this process step.

[0103] Based on the above examples, please refer to Figure 13The barrel-type structure facial tissue laminating device 100 also includes a movable loading structure located at the feeding station 1a, and the movable loading structure includes a loading platform 71 and two movable push plates 72. The loading platform 71 is located below the inner mold 22, and the loading platform 71 has two feeding ports 71a spaced apart along the left and right directions, for respectively allowing the barrel body 201 and the barrel cover 202 to enter; the two movable push plates 72 are arranged corresponding to the two feeding ports 71a, and the two movable push plates 72 are spaced apart on the loading platform 71, and the two movable push plates 72 have a movable stroke close to each other, and the two movable push plates 72 are respectively used to contact the bottom of the barrel body 201 and the top of the barrel cover 202, so as to drive the two to be correspondingly sleeved on the first inner mold 221 and the second inner mold 222. The barrel body 201 and barrel cover 202 can be loaded into the two feed ports 71a via two forward and backward conveyor belts. The two movable push plates 72 can be driven synchronously or separately to complete the left-right sleeve arrangement of the barrel body 201 and barrel cover 202. After the sleeve arrangement is completed, the barrel body 201 and barrel cover 202 are reset to facilitate the subsequent loading of incoming materials. It should be noted that the movable push plates 72 can be driven by a cylinder or a screw. Specifically, the two movable push plates 72 slide along a slide rail to ensure guidance.

[0104] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
