Description

Technical Field

[0001] This invention belongs to the field of stamping equipment technology, and more specifically, relates to an automatic positioning and execution device for stamp management. Background Technology

[0002] Seals, as important office and business tools, are widely used in the signing and confirmation process of various documents, contracts, and vouchers. Traditional automatic seal-stamping equipment typically uses a fixed installation structure, with a single seal head directly connected to or fixed to the drive mechanism to achieve automatic stamping. This type of equipment has significant limitations in applications requiring frequent switching of seal types, such as when multiple departments in a company use seals or banks switch between seals for different business functions. Operators must stop the equipment, manually disassemble and replace the seal head, a cumbersome and time-consuming process that impacts office efficiency. Furthermore, because the connection between the seal and the drive component is often rigid or a simple threaded fit, repeated replacements can easily cause mechanical wear, affecting the accuracy and stability of the stamping position.

[0003] In recent years, some replaceable stamp devices have appeared on the market. Most of them use mechanical snap-fit ​​or screw-on fixing methods, which still require manual alignment and locking during replacement, resulting in insufficient operational convenience. Moreover, after long-term use, the stamp head is prone to wobble due to wear, affecting the stamping quality. Therefore, how to achieve fast, stable, and easily automated stamp replacement has become a key issue in improving the applicability and work efficiency of stamping equipment. Summary of the Invention

[0004] This invention provides an automatic positioning and execution device for seal management, which solves the problems of cumbersome automatic seal replacement, inaccurate stamping due to easy wear and tear of mechanical connections, and difficulty in integrating automated management.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an automatic positioning and execution device for seal management is provided, including a chassis, a seal tray, and a first suction member. A first slide rail extending horizontally is provided at the upper part of the chassis, and a second slide rail extending vertically is slidably connected to the first slide rail. The seal tray is disposed at the lower part of the chassis and is used to support a number of seals. The first suction member is slidably connected to the second slide rail in the vertical direction, and the lower end of the first suction member can suction one of the seals on the seal tray.

[0006] In one possible implementation, the stamp tray is horizontally slidably connected to the chassis along a path perpendicular to the first slide rail. The chassis is provided with a first telescopic member extending downwards. The lower end of the first telescopic member is connected to a protective cover. The stamp tray can move to the bottom of the protective cover and, driven by the first telescopic member, the protective cover covers the top of the stamp tray.

[0007] In some embodiments, the stamp tray is slidably connected to the chassis via a base, the stamp tray is rotatably connected to the base, and several stamps are spaced apart in the circumferential direction of the stamp tray.

[0008] In one possible implementation, the top of the stamp tray is provided with several receiving cylinders for holding stamps, with each receiving cylinder corresponding to a specific stamp.

[0009] In one possible implementation, the chassis includes a paper placement tray located on one side of the stamp tray and a stamping tray located between the paper placement tray and the stamp tray. A third slide rail extending horizontally along a direction perpendicular to the first slide rail is slidably connected to a first slide rail. A second slide rail is slidably connected to the third slide rail. A fourth slide rail extending in a vertical direction is provided on the third slide rail. A second adsorption element for adsorbing paper is slidably connected to the fourth slide rail. The second adsorption element can adsorb paper onto the stamping tray and cause the stamp on the first adsorption element to be stamped.

[0010] In some embodiments, a flipping frame is rotatably connected inside the chassis and framed around the stamping tray. The flipping frame has clamping members on its two opposite inner sidewalls for holding paper. The flipping frame can rotate to flip the paper on the stamping tray.

[0011] In some embodiments, the bottom of the chassis is provided with an upwardly extending second telescopic member, and the stamping plate is connected to the upper end of the second telescopic member. The second telescopic member can drive the stamping plate to move upward to support the paper or to move downward to avoid the paper.

[0012] In some embodiments, two oppositely arranged fingers that can swing toward each other or backward are rotatably connected to the clamping member, and clamping rollers are rotatably connected to the adjacent sides of the two fingers.

[0013] In some embodiments, a saddle-stamping disc is provided between the stamping disc and the stamping tray. One side of the saddle-stamping disc is provided with a pressing member for pressing the paper onto the saddle-stamping disc. The saddle-stamping disc is rotatably connected to the machine housing and can be rotated until the edge seam of the stacked paper on the saddle-stamping disc is in a horizontal state.

[0014] In some embodiments, the top of the pressing member is rotatably connected to a vertically swinging pressure claw, and the side of the pressure claw near the seam stamping plate is rotatably connected to a pressure roller for pressing the paper onto the seam stamping plate.

[0015] The automatic positioning and execution device for seal management provided in this embodiment, compared with the prior art, can automatically and accurately position and pick up any seal on the seal tray through the coordinated cooperation of the first slide rail, the second slide rail and the first suction component, without manual intervention and manual disassembly and replacement, which greatly improves the seal replacement efficiency in multi-seal scenarios.

[0016] The stamp is secured using an electromagnet, resulting in a rapid connection process without the need for repeated alignment and tightening of mechanical clips. This reduces positioning errors caused by human error or mechanical wear. The uniform electromagnet force ensures the stamp remains stable and secure during movement and stamping, guaranteeing accurate and consistent stamping position.

[0017] The overall structure is clear, and complex picking and placing is accomplished through simple sliding and adsorption actions, which reduces the complexity of operation and facilitates automated control and integrated management. Attached Figure Description

[0021] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0022] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on the other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the 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, and therefore should not be construed as a limitation of the invention. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a number" means two or more, unless otherwise explicitly specified.

[0023] Please see Figures 1 to 11The automatic positioning and execution device for seal management provided by the present invention will now be described. The automatic positioning and execution device for seal management includes a housing 10, a seal tray 20, and a first suction member 30. A first slide rail 11 extending horizontally is provided at the upper part of the housing 10, and a second slide rail 12 extending vertically is slidably connected to the first slide rail 11. The seal tray 20 is disposed at the lower part of the housing 10 and is used to support a plurality of seals 21. The first suction member 30 is slidably connected to the second slide rail 12 in the vertical direction, and the lower end of the first suction member 30 can suction one of the seals 21 on the seal tray 20.

[0024] Furthermore, the first adsorption element 30 is an electromagnet.

[0025] This application provides an automatic positioning and execution device for seal management. In actual use, the internal space of the chassis 10 is functionally partitioned, and a first slide rail 11 extending along the first horizontal direction (X-axis) is fixedly installed above the inner cavity. The slide rail is implemented using a precision linear module or guide rail.

[0026] A second slide rail 12 assembly extending vertically (Z-axis) is fixedly connected to the slider of the first slide rail 11, allowing the second slide rail 12 to slide smoothly along the first slide rail 11 with the slider. The first adsorption member 30 (electromagnet) is connected to the second slide rail 12 via the slider and can move up and down vertically along the second slide rail 12.

[0027] Below the inner cavity of the chassis 10, there is an independent stamp tray 20. Multiple stamps 21 with different imprints (such as company seals, financial seals, contract seals, etc.) are fixedly installed or embedded on the tray in an array or ring. The handle of each stamp 21 is usually made of ferromagnetic material or embedded with iron counterweights.

[0028] The device control system coordinates the movement of sliders on the first slide rail 11 and the second slide rail 12, causing the electromagnet to first move horizontally (in the X direction) to above the pre-stored coordinate position of the target stamp 21, and then descend vertically. When the lower end of the electromagnet approaches the top of the stamp 21, it is energized, generating a strong magnetic force to firmly attract the stamp 21. After the stamp is removed, the electromagnet carries the stamp 21 upward and then moves it to the working area via the slide rail system.

[0029] Compared with the prior art, the automatic positioning and execution device for seal management provided in this embodiment can automatically and accurately position and pick up any seal 21 on the seal tray 20 through the coordinated cooperation of the first slide rail 11, the second slide rail 12 and the first suction member 30, without manual intervention and manual disassembly and replacement, which greatly improves the seal replacement efficiency in scenarios with multiple seals 21.

[0030] The stamp 21 is fixed by electromagnet adsorption, which is quick and eliminates the need for repeated alignment and tightening operations with mechanical clips, reducing positioning errors caused by human error or mechanical wear. The uniform adsorption force of the electromagnet ensures that the stamp 21 is stable and does not wobble during movement and stamping, thus guaranteeing the accuracy and consistency of the stamping position.

[0031] The overall structure is clear, and complex picking and placing is accomplished through simple sliding and adsorption actions, which reduces the complexity of operation and facilitates automated control and integrated management.

[0032] In one possible implementation, the aforementioned stamp tray 20 adopts the following... Figure 2 , Figure 3 , Figure 6 and Figure 7 The structure shown is described in the following document. Figure 2 , Figure 3 , Figure 6 and Figure 7 The stamp tray 20 is horizontally slidably connected to the housing 10 along a direction perpendicular to the first slide rail 11. The housing 10 is provided with a downwardly extending first telescopic member 22. The lower end of the first telescopic member 22 is connected to a protective cover 23. The stamp tray 20 can move to the bottom of the protective cover 23 and, driven by the first telescopic member 22, the protective cover 23 covers the top of the stamp tray 20.

[0033] Specifically, the stamp tray 20 is not fixedly installed, but rather slides along a second horizontal direction (Y-axis) perpendicular to the first slide rail 11 via a set of linear guide rails. A vertically arranged first telescopic member 22, such as an electric push rod or servo electric cylinder, is installed on the inner wall or frame of the chassis 10. Its piston rod extends downwards, and its end is fixedly connected to a protective cover 23 made of an opaque, sturdy material (such as metal or engineering plastic). The opening of the protective cover 23 faces downwards and is slightly larger than the stamp tray 20. When the device is in standby mode or not in operation, the control system can drive the stamp tray 20 to slide along the Y-axis to a designated storage area within the chassis 10, which is located directly below the first telescopic member 22. Subsequently, the first telescopic member 22 activates, driving the protective cover 23 to descend smoothly until the entire stamp tray 20 and all the stamps 21 on it are completely enclosed inside the protective cover 23, achieving physical isolation.

[0034] The protective cover 23 can physically isolate the stored seal 21, effectively preventing unauthorized access or theft, and also preventing damage to the seal 21 caused by foreign objects falling in or accidental contact. It is especially suitable for occasions where the security of the seal 21 is highly required.

[0035] Covering the stamp 21 when not in use can reduce dust contamination, keep the stamp surface clean, extend the lifespan of the stamp 21, and make the inside of the device more tidy and organized.

[0036] In some embodiments, see Figure 2 , Figure 3 , Figure 6 and Figure 7 The stamp tray 20 is slidably connected to the chassis 10 via the base 24. The stamp tray 20 is rotatably connected to the base 24. Several stamps 21 are spaced apart around the circumference of the stamp tray 20.

[0037] Specifically, the stamp tray 20 is connected to the chassis 10 via an intermediate base 24. The bottom of the base 24 is horizontally slidably connected to the bottom plate of the chassis 10 in the Y-axis direction via a linear guide pair. At the center of the upper surface of the base 24, a turntable capable of 360-degree horizontal rotation is mounted via a slewing bearing or a large bearing; this turntable serves as the chassis of the stamp tray 20. Multiple stamp mounting seats 21 are evenly distributed along the circumference of the turntable. When a stamp 21 needs to be selected, the control system first drives the base 24 to move along the Y-axis, roughly placing the turntable in the working area, and then precisely controls the rotation of the turntable so that the target stamp 21 is rotated directly below the first adsorption element 30 (electromagnet) to await grasping.

[0038] By rotating the stamp tray 20, a greater number of stamps 21 can be accommodated within a limited planar space. The first suction member 30 only needs to move slightly in the horizontal direction in conjunction with the rotation of the stamp tray 20 to position all the stamps 21, simplifying the design of the lateral drive mechanism.

[0039] By combining rotation and linear sliding, the optimal path can be selected to quickly deliver the target stamp 21 to the area below the first adsorption component 30, thereby improving stamp replacement efficiency.

[0040] In one possible implementation, the aforementioned stamp tray 20 adopts the following... Figure 2 , Figure 3 , Figure 6 and Figure 7 The structure shown is described in the following document. Figure 2 , Figure 3 , Figure 6 and Figure 7 The top of the stamp tray 20 is provided with several receiving cylinders 25 for holding stamps 21, and the several receiving cylinders 25 are set one-to-one with the several stamps 21.

[0041] Specifically, the structure of the stamp tray 20 is described in detail. The top plate of the stamp tray 20 is machined to have multiple circular or square through holes that precisely match the dimensions of the handles of the stamps 21. A vertical receiving cylinder 25 is fixedly installed in each through hole. The inner wall of the receiving cylinder 25 is smooth and can be made of stainless steel or wear-resistant plastic, with a depth less than the length of the handle of the stamp 21. Each stamp 21 is independently inserted into a receiving cylinder 25 and is kept upright by the constraint of the cylinder wall. The top of the stamp 21 (usually a flat top) is higher than the upper edge of the receiving cylinder 25 to facilitate electromagnet attraction.

[0042] The container 25 provides an independent and fixed storage position for each stamp 21, ensuring that the stamp 21 remains upright and stable during equipment movement or operation, and avoiding damage or displacement caused by mutual collision.

[0043] The fixed position of the receiving cylinder 25 provides a precise reference point for the positioning of the first adsorption element 30, allowing the electromagnet to be more accurately aligned with the top of the stamp 21 when it descends, thus improving the success rate and reliability of pickup.

[0044] In one possible implementation, the aforementioned chassis 10 adopts as follows: Figures 2 to 5 The structure shown is described in the following document. Figures 2 to 5 The machine housing 10 is provided with a paper placement tray 40 located on one side of the stamp tray 20 and a stamping tray 50 located between the paper placement tray 40 and the stamp tray 20. A third slide rail 13 extending horizontally along a direction perpendicular to the first slide rail 11 is slidably connected to the first slide rail 11. A second slide rail 12 is slidably connected to the third slide rail 13. A fourth slide rail 14 extending in the vertical direction is provided on the third slide rail 13. A second adsorption member 60 for adsorbing paper is slidably connected to the fourth slide rail 14. The second adsorption member 60 can adsorb paper onto the stamping tray 50 and cause the stamp 21 on the first adsorption member 30 to be stamped.

[0045] Specifically, the internal design of the chassis 10 incorporates multiple functions. The chassis 10 is divided into several functional compartments: a paper tray 40 (paper feeder) that can slide horizontally (along the Y-axis) on one side; a stamping station (with a stamping tray 50) in the middle; and a stamp placement tray 20 (stamp compartment 21) on the side of the stamping tray 50 away from the paper tray 40. The first slide rail 11 (X-axis) serves as the top-level shared motion axis, on which a third slide rail 13 (extending along the Y-axis) that moves along the X-axis is mounted. Two independent motion modules are installed on this third slide rail 13: one is a second slide rail 12 (Z-axis) slidably connected to the first suction element 30, used for stamping; the other is a fourth slide rail 14 (Z-axis), on which a negative pressure suction cup (serving as the second suction element 60) or a suction nozzle assembly driven by a vacuum generator is connected to the slider of the fourth slide rail 14. During operation, the second suction unit 60 first moves above the paper placement tray 40, suctions up the top sheet of paper, and then transfers and precisely places it in the predetermined center position of the stamping tray 50. Subsequently, the first suction unit 30, carrying the selected stamp 21, moves above the paper and performs a pressing stamping action, and this action is repeated.

[0046] It integrates automatic paper picking, paper shifting, positioning and stamping functions. Users only need to put the paper into the paper placement tray 40, and all subsequent steps are completed automatically by the device, achieving a high degree of automation.

[0047] By integrating the paper handling and stamp 21 actuators into the same chassis 10 and sharing some motion rails (such as the first rail 11), the structure is compact, reducing the equipment's footprint and overall complexity.

[0048] The paper handling and stamp 21 can be performed alternately, optimizing the workflow and increasing the processing speed of continuous stamping operations.

[0049] In some embodiments, see Figure 2 , Figure 3 , Figure 10 and Figure 11 Inside the housing 10, there is a rotating frame 70 that is framed around the outer periphery of the stamping tray 50. The two inner side walls of the rotating frame 70 are provided with clamping parts 71 for holding paper. The rotating frame 70 can rotate to turn the paper on the stamping tray 50 over.

[0050] Specifically, a rectangular flip frame 70 is designed around the stamping tray 50. This flip frame 70 is rotatably connected to bearing seats on the side wall of the housing 10 via pivots on both sides, and is driven by a servo motor to rotate 180 degrees forward and backward. A set of clamping components 71 is installed on each of the two short sides inside the flip frame 70. After the paper is placed onto the stamping tray 50 by the second suction component 60 and the front side is stamped, the clamping components 71 actuate (such as pneumatic grippers) to clamp the paper from its two short sides. Then, the drive motor of the flip frame 70 starts, rotating the entire frame and the clamped paper 180 degrees. Afterward, the clamping components 71 release, and the paper, under gravity or auxiliary guidance, lies flat again on the stamping tray 50, with the reverse side facing up, allowing for reverse stamping.

[0051] The paper can be flipped without human intervention, meeting the business needs of stamping both sides of the paper and expanding the equipment's functionality.

[0052] By fixing the paper in place with clamp 71 before rotating, the paper is prevented from drifting, slipping, or wrinkling during the flipping process, ensuring that the paper remains in an accurate position after flipping, which is convenient for positioning the stamp on the reverse side.

[0053] In some embodiments, see Figure 2 , Figure 3 , Figure 10 and Figure 11 The bottom of the casing 10 is provided with an upwardly extending second telescopic member 51. The stamping plate 50 is connected to the upper end of the second telescopic member 51. The second telescopic member 51 can drive the stamping plate 50 to move upward to support the paper or move downward to avoid the paper.

[0054] Specifically, the stamping tray 50 is designed to be height-adjustable. A vertical second telescopic member 51 is connected to the center of the bottom of the stamping tray 50, and the second telescopic member 51 is fixed to the bottom frame of the machine housing 10. When performing single-sided or double-sided stamping on the front side, the second telescopic member 51 rises, lifting the stamping tray 50 to a working height slightly below the lower edge of the flipping frame 70, providing a solid rigid support platform for the paper and ensuring uniform force on the stamped surface. When a flipping operation is required, before or simultaneously with clamping the paper by the clamping member 71, the second telescopic member 51 drives the stamping tray 50 to quickly descend to a low position, providing ample, interference-free space for the rotation of the flipping frame 70 and the lifting and flipping of the clamped paper. After flipping, the stamping tray 50 rises again to support the paper for stamping on the back side.

[0055] The rising support provides stable back support when stamping, allowing the stamp 21 to be clearly and completely stamped on the paper, which is especially effective for soft or uneven paper.

[0056] The lifting design allows the 50-zone stamping tray to meet the support requirements of ordinary stamping while also providing the necessary space for the automatic flipping function, achieving multi-functional reuse of the structure and simplifying the design.

[0057] In some embodiments, see Figure 10 and Figure 11 The clamping member 71 has two oppositely arranged fingers 72 that can swing towards each other or away from each other. The adjacent sides of the two fingers 72 are rotatably connected to clamping rollers 73.

[0058] Specifically, each clamping element 71 has a main body that serves as a mounting base, on which two clamping fingers (bionic finger 72 structure) capable of swinging in opposite directions are mounted via two parallel hinge shafts. At the end of each clamping finger, instead of a flat clamping block, a freely rotating roller is mounted via a short shaft. The surface of this roller can be covered with a flexible friction-enhancing material such as rubber or silicone. When paper clamping is required, the drive mechanism causes the two clamping fingers to swing in opposite directions, and the two clamping rollers 73 contact and press the edges of the paper from both the top and bottom. During the flipping process, the clamping rollers 73 can passively roll along with the movement of the paper.

[0059] A rotatable clamping roller 73 is used to contact and hold the paper edge, replacing the traditional rigid clamping block. During clamping and flipping, the clamping roller 73 rolls against the paper, greatly reducing the risk of indentation, tearing or wrinkling of the paper edge, making it especially suitable for important documents or more fragile paper.

[0060] The two opposing swinging fingers 72 structure can adapt to a stack or multiple sheets of paper of different thicknesses, and the clamping rollers 73 provide uniform clamping force to ensure that the paper does not slip during the flipping process.

[0061] In some embodiments, see Figure 2 , Figure 3 , Figure 8 and Figure 9 A stamping tray 80 is provided between the stamping tray 50 and the stamping tray 20. A pressing member 90 for pressing down paper on the stamping tray 80 is provided on one side of the stamping tray 80. The stamping tray 80 is rotatably connected to the machine housing 10. The stamping tray 80 can be rotated until the edge seam of the paper stacked on the stamping tray 80 is in a horizontal state.

[0062] Specifically, a dedicated stamping station with overlapping seams is created within the chassis 10, located between the stamping tray 50 and the stamp placement tray 20. This station is equipped with a stamping tray 80 with overlapping seams, which can slide horizontally along the Y-axis into and out of the work area via a sliding mechanism (facilitating stamping completion and output to the chassis 10). Simultaneously, the stamping tray 80 itself can rotate around a horizontal axis. A pressing component 90 is installed on one side of the stamping tray 80. When overlapping seams need to be stamped, the second suction component 60 stacks the papers from the stamping tray 50 onto the stamping tray 80 in a staggered manner, ensuring the seam side is close to the edge of the stamping tray 80. The pressing component 90 then actuates, firmly pressing and fixing the side area of ​​the document stack onto the stamping tray. Then, the stamping tray 80 is driven to rotate, controlled by an angle sensor, until the side seam of the document stack (i.e., the intersection of the edges of each page) is precisely adjusted to a horizontal state. At this point, the first adsorption element 30, carrying the special cross-seam stamp 21, moves to directly above the horizontal seam and presses down vertically to complete the cross-seam stamping across multiple pages.

[0063] A specially designed mechanism for fixing and multi-page documents along the sides, as well as an adjustable stamp plate, solves the problem that traditional automatic stamping equipment struggles to handle seals across the seams.

[0064] By pressing down to fix the seal and rotating to adjust it, the edge seams of multi-page documents can be tightly aligned and kept horizontal, thus ensuring that the seal across the seams can be clearly affixed to the side seams of each page, in compliance with legal and business requirements.

[0065] The device integrates both flat stamping and cross-stitch stamping functions, meeting complex and comprehensive stamping needs.

[0066] In some embodiments, see Figure 8 and Figure 9 The top of the pressing member 90 is rotatably connected to a pressing claw 91 that can swing vertically, and the side of the pressing claw 91 near the seam stamping plate 80 is rotatably connected to a pressing roller 92 for pressing the paper onto the seam stamping plate 80.

[0067] Specifically, the actuating end of the pressing component 90 (pneumatic gripper) is a pressure claw 91 that can swing vertically slightly via a hinge. The swing center of the pressure claw 91 is located at its upper part. On the side of the pressure claw 91 near the binding seal plate 80 (outer side), a freely rotating pressure roller 92 is installed, with the axis of the pressure roller 92 parallel to the side edge of the document. When the pressure claw 91 swings down (outward swings) under the action of the driving component, the pressure roller 92 first contacts the upper surface of the side edge of the document stack, and as it continues to press down, the pressure roller 92 rolls along the document surface, eventually pressing the document stack tightly onto the binding seal plate 80. The rotation axis of the pressure roller 92 can be designed to float slightly to accommodate unevenness of the document surface.

[0068] The pressure claw 91 is oscillating, and the pressure roller 92 is rolling, allowing downward pressure to be smoothly applied to the edges of the document stack and to accommodate small variations in the stack thickness. The rolling contact reduces friction, preventing scratches on the paper surface or paper shifting during clamping.

[0069] The pressure roller 92 can evenly distribute the pressure along a line, ensuring that the side of the document stack to be stamped is stably pressed against the seal plate 80, preventing the paper from springing back or moving at the moment of stamping, thereby ensuring the clarity and positional accuracy of the seal.

[0070] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
