Description

Technical Field

[0001] This invention relates to the field of fireworks production and processing technology, specifically to a combined fireworks production device. Background Technology

[0002] The production process of fireworks involves processes such as propellant preparation, feeding, and loading; filling and punching holes in the base paper; assembling effect components (firework inner tubes); filling and punching holes in the face paper; and packaging. Among these, the assembly between the outer tube and the inner tube filled with gunpowder is a crucial step in the production technology. Traditionally, this was all done manually, resulting in low production efficiency, high labor intensity, and inability to guarantee quality requirements. With the development of the manufacturing industry, fully automated fireworks production equipment has emerged. However, in the current market, fireworks production equipment is prone to congestion during the movement and delivery of the inner tube during automated production, leading to instability in the automatic transfer process and affecting subsequent assembly. At the same time, the outer tubes are prone to misalignment, and there may be misalignment between the outer and inner tubes, preventing the inner tube from accurately falling into the outer tube and resulting in missing parts. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a combined fireworks production apparatus to solve the aforementioned technical problems.

[0004] This invention provides a combined fireworks production device, including an arranging assembly, a material feeding assembly, and a vibrating conveyor assembly. The arranging assembly includes a conveyor belt structure, a limiting structure, and a correction structure. The conveyor belt structure transports multiple outer cylinders. The limiting structure and the correction structure are mounted above the conveyor belt structure. The limiting structure restricts the multiple outer cylinders to preset positions on the conveyor belt structure, and the correction structure arranges the multiple outer cylinders neatly to form a combined cylinder. The vibrating conveyor assembly includes a vibrating structure and multiple first outlets located on the left side of the vibrating structure. Multiple inner cylinders are placed on the vibrating structure. The material feeding assembly includes a clamping feeding structure, a transferring structure, and a material feeding structure. The material feeding structure is located on the... Above the combined cylinder, the clamping and feeding structure is connected to multiple first outlets. The vibration structure is used to sequentially feed multiple inner cylinders from the first outlets into the dropping structure. The transfer structure is used to move to directly below the clamping and feeding structure. The clamping and feeding structure is used to feed multiple inner cylinders into the transfer structure and limit the inner cylinders on the vibration structure during the feeding process, so that the inner cylinders on the vibration structure cannot enter the clamping and feeding structure. The transfer structure is also used to carry multiple inner cylinders to directly above the combined cylinder. The transfer structure is also used to send the multiple inner cylinders it carries out into the dropping structure and the combined cylinder. The dropping structure is used to empty the multiple inner cylinders carried by the transfer structure and allow the multiple inner cylinders to enter the combined cylinder. In the entire combined fireworks production device, the vibrating conveyor assembly's vibrating structure continuously vibrates, causing multiple inner cylinders on it to move to the left. The vibrating structure also has channels for arranging the inner cylinders, each corresponding to a first outlet. This allows the inner cylinders to automatically arrange themselves during movement and sequentially exit the vibrating structure from the first outlet. Furthermore, a positioning feeding structure connects to the first outlet, allowing the inner cylinders to directly enter the positioning feeding structure. When the conveying structure moves directly below the positioning feeding structure, it begins feeding. Simultaneously, the positioning feeding structure limits the movement of the inner cylinders on the vibrating structure, preventing them from continuing to enter the vibrating structure. Within the clamping and feeding structure, not only can multiple points of neat feeding be achieved, improving feeding efficiency, but more importantly, it prevents the next batch of inner cylinders from continuously flowing into the clamping and feeding structure from the first outlet while one batch of inner cylinders moves out of the structure. This avoids congestion on the route between the first outlet and the transfer structure, ensuring an orderly and reliable feeding process. Furthermore, the entire transfer structure can use its own structure to neatly arrange the inner cylinders, thereby improving the neatness of the entire assembly process. At the same time, the limiting and correction structures in the arrangement components improve the neatness of the multiple outer cylinders forming the combined cylinder body. This ensures that after the material unloading structure empties the inner cylinders of the transfer structure, the multiple inner cylinders will neatly and reliably enter the multiple outer cylinders of the combined cylinder body, thus completing a stable assembly production process.

[0005] Preferably, the positioning and feeding structure includes an arrangement cavity connected to multiple first outlets, a pushing and limiting part is provided at the top of the arrangement cavity, multiple second outlets are provided at the bottom of the arrangement cavity, and a first stop part that can move horizontally is provided at the bottom of the arrangement cavity; wherein, the vibration structure is used to feed multiple inner cylinders sequentially from the first outlets into the arrangement cavity; the pushing and limiting part includes multiple limiting buckets that can move up and down, and the limiting buckets can pass through the arrangement cavity and extend into the second outlets after moving downwards; the first stop part is located below the second outlet and is used to block or move out directly below the second outlet. The arranging cavity can arrange multiple inner cylinders, each facing a different second outlet. If the conveying structure is not directly below the arranging cavity, the first stop blocks the area directly below the second outlet, preventing the inner cylinders from falling out of the arranging cavity. When the conveying structure moves directly below the arranging cavity, the limiting bucket descends, and as it enters the arranging cavity, the first stop moves out from directly below the second outlet. At this point, the inner cylinders inside the arranging cavity begin to fall, and the limiting bucket begins to occupy the internal space of the arranging cavity. The inclined outer wall of the limiting bucket will contact and push out the inner cylinder closest to the arranging cavity in the horizontal direction, thus preventing the inner cylinders from continuously entering the entire arranging cavity from the first outlet, thereby avoiding congestion and improving the reliability of the entire assembly and production process. At the same time, the bottom of the limiting bucket can abut against the inner cylinder stuck at the second outlet, effectively emptying the inner cylinders inside the arranging cavity.

[0006] Preferably, the arrangement cavity is provided with multiple partitions, and an arrangement space is formed between adjacent partitions. The second outlet is opened at the bottom of the arrangement space, and multiple limiting hoppers are respectively located above the multiple arrangement spaces. The partitions and arrangement spaces can play a role in arranging the multiple inner cylinders neatly.

[0007] Preferably, the transfer structure includes a horizontally moving part, which includes two horizontally movable sliding bases. A storage part is provided between the two sliding bases. The storage part has multiple storage channels. The top end of each storage channel extends through the top surface of the storage part to form a first opening, and the bottom end of each storage channel extends through the bottom surface of the storage part to form a second opening. A second stop is provided at the bottom of the second opening. The sliding base is used to move the storage part to directly below the clamping and feeding structure after movement, so that multiple inner cylinders can enter the storage channels. The sliding base is used to move the storage part to directly above the combined cylinder after movement. The second stop is used to block or move out of the area directly below the second opening. The horizontal moving part can be driven by gears and racks to meet the requirements of precise position control, and the sliding base is fixed on the toothed belt; the size of the storage channel is slightly larger than the size of the inner cylinder; the inner cylinder falls into the storage channel from the first opening and is restricted in the storage channel by the second gear structure. When the storage part moves to the top of the combined cylinder, and the storage channel is directly opposite the multiple outer cylinders of the combined cylinder, or directly opposite the temporary storage structure of the material dropping structure, the second gear part can be moved out directly below the second opening. At this time, the inner cylinder can fall out of the temporary storage structure from the second opening by gravity.

[0008] Preferably, the first stop portion includes a first telescopic rod, the end of which is fixed with a first baffle, which is located below the second outlet; the second stop portion includes a second telescopic rod, the end of which is fixed with a second baffle, which is located below the second opening. After extension and retraction, the first and second telescopic rods can respectively move the first and second baffles to meet the requirements.

[0009] Preferably, at least two storage compartments are provided between the two sliding seats. At least two storage compartments can increase the number of inner cylinders assembled during a single cycle of the sliding seats, thereby improving production efficiency.

[0010] Preferably, the material discharge structure includes a guide plate fixed directly above the combined cylinder and a material clearing push rod assembly located directly above the guide plate. The material clearing push rod assembly includes multiple lifting rods capable of moving up and down. The guide plate has multiple bucket-shaped guide channels, the bottom of which faces the outer cylinder. The lifting rods are used to pass through the guide channels and enter the outer cylinder after moving up and down. When the transfer structure moves directly above the combined cylinder, the lifting rods are also used to clear the multiple inner cylinders carried within the transfer structure after moving up and down. The bottom dimension of the guide channels on the guide plate is equal to or slightly larger than the outer diameter of the inner cylinder by 1mm, ensuring that the inner cylinder is slightly jammed by the guide channels during its descent, preventing excessive gravitational potential energy of the inner cylinder and facilitating interaction with the lifting rods. Furthermore, the fixed position of each guide channel ensures a more stable and reliable correspondence with the multiple outer cylinders of the combined cylinder. Therefore, when the guide channels are bucket-shaped (larger at the top and smaller at the bottom), the inner cylinder will continuously adjust its orientation during its descent, allowing it to fall more accurately into the outer cylinder.

[0011] Preferably, the limiting structure includes a limiting rod positioned above the conveyor belt structure. The limiting rod abuts against multiple outer cylinders, allowing the outer cylinders to be aligned while simultaneously stacking to meet the requirements for forming a combined cylinder.

[0012] Preferably, the correction structure includes a first correction part and a second correction part disposed on the left and right sides above the conveyor belt structure. The first correction part includes a correction claw capable of horizontal movement. The front, left, and right sides of the combined cylinder respectively abut against the first correction part, the limiting rod, and the second correction part. The first and second correction parts limit the width of the combined cylinder, while the correction claw of the first correction part pushes multiple outer cylinders, ensuring they are fully against the second correction part and arranged as neatly as possible, eliminating gaps between adjacent outer cylinders.

[0013] Preferably, the conveyor belt structure includes a conveyor belt plane, under which a lifting plate capable of being raised and lowered is disposed. The correction structure further includes multiple correction cones disposed directly above the combined cylinder. The lifting plate, upon rising, drives the conveyor belt plane upward, causing the multiple correction cones to respectively engage in multiple gaps at the top of the combined cylinder. The lifting plate moves the combined cylinder upward, allowing the multiple correction cones to engage in the gaps at the top of the combined cylinder. This achieves secondary correction, ensuring the neatness of the combined cylinder, and also reduces the distance the inner cylinder needs to travel into the outer cylinder, allowing the inner cylinder to fall precisely into the outer cylinder.

[0014] Compared with the prior art, the combined fireworks production apparatus of this application has at least the following beneficial effects:

[0015] In this invention, the vibrating structure of the vibrating conveying assembly continuously vibrates, causing multiple inner cylinders on it to move to the left. The vibrating structure also has channels for arranging the inner cylinders, each corresponding to a first outlet. This allows the inner cylinders to automatically arrange themselves during movement and sequentially exit the vibrating structure from the first outlet. Furthermore, a locking feeding structure connects to the first outlet, allowing the inner cylinders to directly enter the locking feeding structure from the first outlet. When the conveying structure moves directly below the locking feeding structure, the locking feeding structure begins feeding. Simultaneously, the locking feeding structure limits the movement of the inner cylinders on the vibrating structure, preventing further entry of inner cylinders from the vibrating structure into the locking position. Within the feeding structure, this not only enables neat multi-point feeding and improves feeding efficiency, but more importantly, it prevents the next batch of inner cylinders from continuously flowing into the feeding structure from the first outlet while one batch of inner cylinders moves out of the feeding structure. This avoids congestion on the route between the first outlet and the transfer structure, ensuring an orderly and reliable feeding process. Furthermore, the entire transfer structure can use its own structure to neatly arrange the inner cylinders, thereby improving the neatness of the entire assembly process. At the same time, the limiting and correction structures in the arrangement components improve the neatness of the multiple outer cylinders forming the combined cylinder body. This ensures that after the material unloading structure empties the inner cylinders of the transfer structure, the multiple inner cylinders will neatly and reliably enter the multiple outer cylinders of the combined cylinder body, thus completing a stable assembly production process.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] In the description of the embodiments of the present invention, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0029] like Figures 1 to 6 As shown, the present invention provides a combined fireworks production device, including an arrangement assembly 1, a material feeding assembly 2, and a vibrating conveyor assembly 3; wherein, the arrangement assembly 1 includes a conveyor belt structure 11, a limiting structure 12, and a correction structure 13, the conveyor belt structure 11 is used to convey multiple outer cylinders 41, the limiting structure 12 and the correction structure 13 are mounted above the conveyor belt structure 11, the limiting structure 12 is used to restrict the multiple outer cylinders 41 to a preset position on the conveyor belt structure 11, and the correction structure 13 is used to arrange the multiple outer cylinders 41 neatly to form a combined cylinder 4; the vibrating conveyor assembly 3 includes a vibrating structure 31 and multiple first outlets 32 located on the left side of the vibrating structure 31, multiple inner cylinders are placed on the vibrating structure 31, the material feeding assembly 2 includes a clamping feeding structure 21, a transferring structure 22, and a material feeding structure 23 ... Structure 23 is located directly above the combined cylinder 4. The clamping and feeding structure 21 is connected to multiple first outlets 32. The vibration structure 31 is used to sequentially feed multiple inner cylinders from the first outlets 32 into the discharge structure 23. The transfer structure 22 is used to move to directly below the clamping and feeding structure 21. The clamping and feeding structure 21 is used to feed multiple inner cylinders into the transfer structure 22 and limit the inner cylinders on the vibration structure 31 during the feeding process so that the inner cylinders on the vibration structure 31 cannot enter the clamping and feeding structure 21. The transfer structure 22 is also used to carry multiple inner cylinders to directly above the combined cylinder 4. The transfer structure 22 is also used to send the multiple inner cylinders it carries out to the discharge structure 23 and the combined cylinder 4. The discharge structure 23 is used to empty the multiple inner cylinders carried by the transfer structure 22 and allow the multiple inner cylinders to enter the combined cylinder 4.

[0030] In this embodiment, it should be noted that in the entire combined fireworks production device, such as Figure 1As shown, the vibration structure 31 of the vibration conveying assembly 3 continuously vibrates, causing multiple inner cylinders on it to move to the left. The vibration structure 31 also has arrangement channels for arranging the inner cylinders, each corresponding to a first outlet 32. This allows the inner cylinders to automatically arrange themselves during movement and sequentially exit the vibration structure 31 from the first outlet 32. Furthermore, by connecting the first outlet 32 ​​using the positioning feeding structure 21, the inner cylinders directly enter the positioning feeding structure 21 from the first outlet 32. When the transfer structure 22 moves directly below the positioning feeding structure 21, the positioning feeding structure 21 begins feeding. While feeding the arranged inner cylinders into the transfer structure 22, the positioning feeding structure 21 also limits the movement of the inner cylinders on the vibration structure 31, preventing them from continuing to enter the positioning feeding structure 21. This not only achieves neat multi-point feeding and improves feeding efficiency, but also... More importantly, it avoids congestion on the route between the first outlet 32 ​​and the transfer structure 22 while one batch of inner cylinders is being moved out of the clamping and feeding structure 21, ensuring that the feeding process proceeds in an orderly and reliable manner. Furthermore, the entire transfer structure 22 can use its own structure to neatly arrange the inner cylinders, thereby improving the neatness of the entire assembly process. At the same time, the limiting structure 12 and the correction structure 13 in the arrangement component 1 are used to improve the neatness of the multiple outer cylinders 41 forming the combined cylinder 4. This ensures that after the unloading structure 23 empties the inner cylinders of the transfer structure 22, the multiple inner cylinders will neatly and reliably enter the multiple outer cylinders 41 of the combined cylinder 4, thereby completing a stable assembly production process. Moreover, the assembly is completed by the sequentially linked automated operation of the arrangement component 1, the unloading component 2, and the vibrating conveying component 3, which reduces the risk factor, significantly improves safety, and ensures safe production.

[0031] Specifically, the positioning and feeding structure 21 includes an arrangement cavity 211 connected to multiple first outlets 32. A push limiting part 212 is provided at the top of the arrangement cavity 211, and multiple second outlets 2111 are opened at the bottom of the arrangement cavity 211. A first stop part 213 that can move horizontally is provided at the bottom of the arrangement cavity 211. The vibration structure 31 is used to feed multiple inner cylinders from the first outlets 32 into the arrangement cavity 211 in sequence. The push limiting part 212 includes multiple limiting buckets 2121 that can move up and down. After the limiting buckets 2121 move downward, they can pass through the arrangement cavity 211 and extend into the second outlets 2111. The first stop part 213 is located below the second outlets 2111 and is used to block or move out directly below the second outlets 2111.

[0032] In this embodiment, it should be noted that the arranging cavity 211 can arrange multiple inner cylinders so that each inner cylinder is directly opposite a multiple second outlet 2111. If the conveying structure 22 is not located directly below the arranging cavity 211, the first stop portion blocks the area directly below the second outlet 2111, preventing the inner cylinders from falling out of the arranging cavity 211 from the second outlet 2111. If the conveying structure 22 moves to the area directly below the arranging cavity 211, the limiting bucket 2121 descends, and as the limiting bucket 2121 enters the arranging cavity 211, the first stop portion 213 moves out of the first outlet 2111. Directly below the second outlet 2111, the inner cylinder inside the arrangement cavity 211 begins to fall, and the limiting bucket 2121 begins to occupy the internal space of the arrangement cavity 211. The inclined outer wall of the limiting bucket 2121 will contact and push out the inner cylinder closest to the arrangement cavity 211 in the horizontal direction, thereby preventing the inner cylinder from continuously entering the entire arrangement cavity 211 from the first outlet 32, thus avoiding congestion and improving the reliability of the entire assembly and production process. At the same time, the bottom end of the limiting bucket 2121 can abut against the inner cylinder stuck at the second outlet 2111, which plays the role of emptying the inner cylinder inside the arrangement cavity 211.

[0033] Specifically, the arrangement cavity 211 is provided with multiple partitions 2112, and an arrangement space 2113 is formed between adjacent partitions 2112. A second outlet 2111 is opened at the bottom of the arrangement space 2113, and multiple limiting buckets 2121 are located above the multiple arrangement spaces 2113 respectively.

[0034] In this embodiment, it should be noted that the partition 2112 and the arrangement space 2113 can serve to arrange multiple inner cylinders neatly.

[0035] Specifically, the transfer structure 22 includes a horizontal moving part 221, which includes two horizontally movable sliding bases 2211. A storage part 222 is provided between the two sliding bases 2211. The storage part 222 has multiple storage channels 2221. The top end of the storage channel 2221 extends out of the top surface of the storage part 222 and forms a first opening. The bottom end of the storage channel 2221 extends out of the bottom surface of the storage part 222 and forms a second opening. A second stop part 223 is provided at the bottom of the second opening. The sliding base 2211 is used to move the storage part 222 to directly below the clamping and feeding structure 21 after movement, so that multiple inner cylinders can enter the storage channel 2221. The sliding base 2211 is used to move the storage part 222 to directly above the combined cylinder body 4 after movement. The second stop part 223 is used to block or move out of the area directly below the second opening.

[0036] In this embodiment, it should be noted that the horizontal moving part 221 can be driven by gears and racks to meet the requirements of precise position control, and the sliding base 2211 is fixed on the toothed belt; the size of the storage channel 2221 is slightly larger than the size of the inner cylinder; the inner cylinder falls into the storage channel 2221 from the first opening and is restricted in the storage channel 2221 by the second gear structure. When the storage part 222 moves to the top of the combined cylinder 4, and the storage channel 2221 is directly opposite the multiple outer cylinders 41 of the combined cylinder 4, or directly opposite the temporary storage structure of the material dropping structure 23, the second gear part can be moved out directly below the second opening. At this time, the inner cylinder can fall out of the temporary storage structure from the second opening by gravity.

[0037] Specifically, the first gear position 213 includes a first telescopic rod 2131, and a first baffle 2132 is fixed to the end of the first telescopic rod 2131. The first baffle 2132 is located below the second outlet 2111. The second gear position 223 includes a second telescopic rod 2231, and a second baffle 2232 is fixed to the end of the second telescopic rod 2231. The second baffle 2232 is located below the second opening.

[0038] In this embodiment, it should be noted that after the first telescopic rod 2131 and the second telescopic rod 2231 extend or retract, they can respectively drive the first baffle 2132 and the second baffle 2232 to move, thereby meeting the requirements.

[0039] Specifically, at least two storage sections 222 are provided between the two sliding seats.

[0040] In this embodiment, it should be noted that at least two storage sections 222 can increase the number of inner cylinders assembled in a single cycle of the sliding seat, thereby improving production efficiency.

[0041] Specifically, the material discharge structure 23 includes a guide plate 232 fixed directly above the combined cylinder 4 and a material clearing push rod assembly 231 located directly above the guide plate 232. The material clearing push rod assembly 231 includes multiple lifting rods 2311 that can move up and down. The guide plate 232 has multiple bucket-shaped guide channels 2321, with the bottom of the guide channels 2321 facing the outer cylinder 41. The lifting rods 2311 are used to pass through the guide channels 2321 and enter the outer cylinder 41 after moving up and down. When the transfer structure 22 moves to directly above the combined cylinder 4, the lifting rods 2311 are also used to clear the multiple inner cylinders carried in the transfer structure 22 after moving up and down.

[0042] In this embodiment, it should be noted that the bottom dimension of the guide channel 2321 on the guide plate 232 is equal to or slightly larger than the outer diameter of the inner cylinder by 1mm. This ensures that the inner cylinder is slightly stuck by the guide channel 2321 during the descent, preventing excessive gravitational potential energy of the inner cylinder and facilitating interaction with the lifting rod 2311. Furthermore, the positions of each guide channel 2321 are fixed, making the correspondence between them and the multiple outer cylinders 41 of the combined cylinder 4 more stable and reliable. Therefore, when the guide channel 2321 is in the shape of a bucket with a larger top and a smaller bottom, the inner cylinder will continuously adjust its orientation during the descent, thereby allowing the inner cylinder to fall more accurately into the inner cylinder 41.

[0043] Specifically, the limiting structure 12 includes a limiting rod 121 that is positioned above the conveyor belt structure 11.

[0044] In this embodiment, it should be noted that the limiting rod 121 abuts against the multiple outer cylinders 41, so that the outer cylinders 41 are aligned and the multiple outer cylinders 41 are continuously stacked to meet the need to form the combined cylinder 4.

[0045] Specifically, the correction structure 13 includes a first correction part 131 and a second correction part 132 disposed on the left and right sides above the conveyor belt structure 11. The first correction part 131 includes a correction claw 1311 that can move horizontally. The front, left and right sides of the combined cylinder 4 respectively abut against the first correction part 131, the limiting rod 121 and the second correction part 132.

[0046] In this embodiment, it should be noted that the first correction part 131 and the second correction part 132 limit the width of the combined cylinder 4. At the same time, the correction claw 1311 of the first correction part 131 can push multiple outer cylinders 41 so that the outer cylinders 41 and the second correction part 132 can fully abut against each other and be arranged as neatly as possible to eliminate the gaps between adjacent outer cylinders 41.

[0047] Specifically, the conveyor belt structure 11 includes a conveyor belt plane 111, and a lifting plate 112 that can be raised and lowered is provided under the conveyor belt plane 111. The correction structure 13 also includes a plurality of correction cones 133 arranged directly above the combined cylinder 4. The lifting plate 112 is used to drive the conveyor belt plane 111 to rise after it rises, so that the plurality of correction cones 133 are respectively inserted into a plurality of gaps at the top of the combined cylinder 4.

[0048] In this embodiment, it should be noted that the lifting plate 112 drives the combined cylinder 4 to move upward, so that multiple correction cones 133 are inserted into the gap at the top of the combined cylinder 4. On the one hand, secondary correction is achieved to fully ensure the neatness of the combined cylinder 4. On the other hand, it can also reduce the distance of the inner cylinder into the outer cylinder 41, so that the inner cylinder can fall accurately into the outer cylinder 41.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
