Description

Technical Field

[0001] This invention relates to the field of new energy vehicle manufacturing technology, and in particular to a concealed ultra-thin lifting transplanter suitable for transmission mechanisms. Background Technology

[0002] With increasing global emphasis on environmental protection and sustainable development, the new energy vehicle industry has ushered in unprecedented development opportunities. New energy vehicles, especially electric vehicles, are gradually becoming the mainstream development direction of the automotive industry due to their advantages such as zero emissions, low noise, and high efficiency. In the manufacturing process of new energy vehicles, the efficiency, precision, and flexibility of automated production lines are crucial for improving production efficiency, ensuring product quality, and reducing production costs.

[0003] In both traditional automobile manufacturing and new energy vehicle production, the transfer and relocation of components are crucial aspects of the production line. However, traditional transfer mechanisms and equipment often suffer from the following problems: On the one hand, conventional conveying mechanisms struggle to accurately detect and adjust the center of gravity of objects during transport. When objects are placed with deviations or have irregular shapes, their center of gravity deviates from the ideal position. When the lifting mechanism lifts the object, the unstable center of gravity can easily cause the lifting platform to tilt, affecting the transfer accuracy of the object and potentially damaging it, thus reducing the yield rate.

[0004] On the other hand, existing lifting and transferring equipment often uses complex and costly detection devices to check the center of gravity and transfer status of objects. This not only increases the overall cost of the equipment, but also makes these detection devices difficult to maintain. If a malfunction occurs, the repair time is long, which will seriously affect the production schedule. At the same time, traditional equipment often requires additional complex sorting devices or manual intervention to separate qualified products from defective products, which is inefficient and prone to errors.

[0005] In addition, as industrial production demands higher equipment space utilization, the shortcomings of traditional lifting and transplanting equipment, such as large size and insufficient compact structure, are becoming increasingly apparent, making it difficult to meet the needs of some production scenarios with strict space constraints.

[0006] Therefore, a concealed ultra-thin lifting transplanter suitable for transmission mechanisms is proposed to solve the problems of low efficiency in detecting the center of gravity of objects, stable transmission and transplanting, and low space utilization of existing lifting machines. Summary of the Invention

[0007] The purpose of this invention is to solve the problems of low efficiency in detecting the center of gravity of objects, stable transmission and transplanting, and low space utilization of existing lifting machines, and to propose a hidden ultra-thin lifting transplanting machine suitable for the transmission mechanism.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A concealed ultra-thin lifting transplanter suitable for a transmission mechanism includes a transmission mechanism and a lifting mechanism. The transmission mechanism includes a base and a plurality of conveying rollers rotatably connected thereto. The lifting mechanism is disposed on the base and between the conveying rollers. The lifting mechanism includes several cylinders fixed to the inner walls of both sides of the base. The cylinders on both sides are alternately distributed and their output ends face the opposite side of the base and are fixed with sliding blocks. The top of the sliding blocks on the same side is fixed with a support plate. A shearing mechanism is provided between the two support plates. The top of the shearing mechanism is fixed with a lifting platform. The end face of the lifting platform is provided with several mounting grooves with a width greater than the outer diameter of the conveying roller. The lifting platform is located on the sliding path of the gap between the conveying rollers. The lifting platform is equipped with visual sensors for observing objects at both ends, and the outer wall array of the conveyor rollers adjacent to both ends of the lifting platform and the conveyor rollers in the mounting groove is provided with several sliding grooves. A pressure detection block is slidably connected inside the sliding groove. A detection groove is coaxially opened at the bottom of the sliding groove, and a high-sensitivity sensor is installed inside the detection groove. A second mounting groove is coaxially opened at the bottom of the detection groove. A spring is fixed at the bottom of the second mounting groove, and the other end of the spring is fixed to the pressure detection block. An annular ventilation channel communicating with the second mounting groove is opened on the inner wall between the second mounting grooves. When the pressure detection block is subjected to the weight of the object, the compression spring is subjected to force, thereby changing the pressure on the inner wall of the detection groove, and then the distance moved by the pressure detection block is detected by a high-sensitivity sensor.

[0009] Preferably, the base of the transmission mechanism has horizontally opened fixing grooves on both sides of the inner wall, and the two ends of the fixing grooves have longitudinally extended sliding grooves. A support plate is installed in both the fixed groove and the sliding groove. The fixed groove is fixedly connected to the support plate, and the sliding groove is slidably connected to the support plate. Mounting holes are correspondingly arrayed on both sides of the support plate. The conveying roller is rotatably mounted through the mounting holes, and the shaft of the conveying roller passes through the mounting holes and is fixed with pulleys at both ends. All pulleys on the same side are fitted with a belt. A motor is slidably connected to the inner wall of the base on the same side as the belt. A pulley is fixed to the output end of the motor. The axis of the pulley is lower than that of the pulley.

[0010] Preferably, a bearing is fixed between the pulley two and the inner wall of the base, and a telescopic rod is installed on the outer wall of the bearing one. The fixed end of the telescopic rod is fixed to the base, and the output end is fixed to the bearing one. The telescopic rod extends and retracts in the same direction as the belt tightens and loosens.

[0011] Preferably, a cylinder is provided at the bottom of the support plate in the sliding groove, the fixed end of the cylinder is fixed to the base, and the output end is fixed to the bottom of the support plate.

[0012] Preferably, a second motor is fixed to the inner wall of the base. The second motor is located on the side away from the first motor and corresponds to the longitudinal position of the lifting platform. A third pulley is fixed to the output end of the second motor. The third pulley is compatible with the model of the first pulley and its axis height is lower than that of the first pulley. The conveyor rollers at both ends of the lifting platform and in the mounting groove are fitted with belt 2 together with pulley 1 and pulley 3.

[0013] Preferably, the base has two mounting plates fixed to its bottom, the two mounting plates are located on both sides of the lifting mechanism, and are slidably connected to a connecting plate; The connecting plate has an arc-shaped groove adapted to the conveying roller, and the edge of the arc-shaped groove has a rounded chamfer; the connecting plate has several through holes adapted to the shearing mechanism, and the positions of the through holes correspond to the distribution of the connecting rods of the shearing mechanism.

[0014] Preferably, the two mounting plates have mounting grooves on their side walls, a cylinder is fixed in the mounting groove, a wedge is fixed at the output end of the cylinder, and the wedge is located below the connecting plate; the bottom of the connecting plate has a chamfer that matches the wedge.

[0015] Preferably, the high-sensitivity sensor probe faces the bottom end face of the pressure detection block, and the signal is connected to the control system. The control system is electrically connected to motor one, motor two, cylinder one, cylinder two, cylinder three and telescopic rod, and controls the start and stop of each component.

[0016] Preferably, the inner diameter of the detection groove is smaller than the inner diameter of the sliding groove, forming a stepped structure.

[0017] Preferably, the annular ventilation channel communicates with all mounting slots 2. The beneficial effects of this invention are: This equipment, by setting pressure detection blocks, high-sensitivity sensors, and a matching control system on the conveyor rollers, can detect the pressure distribution of various parts when an object is placed on the conveyor rollers in real time and accurately, thereby accurately determining the center of gravity position of the object. Furthermore, the drive system composed of motor 2, pulley 3, and belt 2 can automatically adjust objects with offset centers of gravity, ensuring that the object's center of gravity is accurately located at the center of the lifting platform. This effectively avoids the problem of the lifting platform tilting due to unstable centers of gravity, greatly improving the accuracy and stability of object transfer, reducing the risk of object damage, and increasing the production yield. In conveying mode, the motor drives all conveyor rollers to rotate synchronously via a belt, achieving horizontal conveying of objects. This transmission method has a simple structure and high transmission efficiency, ensuring that objects are transported smoothly and quickly to the designated position. In lifting mode, the cylinder drives the shearing mechanism to achieve synchronous, stable, and offset shearing action, precisely lifting the lifting platform and allowing the conveyor rollers to be precisely embedded into the mounting slots of the lifting platform. This avoids mechanical interference and achieves stable receiving and transfer of objects. The entire transmission and transfer process is efficient and smooth. The equipment features a concealed, ultra-thin design. The lifting mechanism is cleverly positioned on the base of the transmission mechanism and between the conveyor rollers, making full use of space. This results in a compact structure with a small footprint, making it suitable for production scenarios with strict space constraints and improving space utilization. Furthermore, the rational layout of the components facilitates installation and maintenance, reducing maintenance costs and ease of use. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figure 1 - Figure 10 A concealed ultra-thin lifting transplanter suitable for a transmission mechanism includes a transmission mechanism 1 and a lifting mechanism 2.

[0022] The transmission mechanism 1 includes a base 101 and a plurality of transmission rollers 102 rotatably connected thereto. The lifting mechanism 2 is disposed on the base 101 and between the transmission rollers 102.

[0023] The base 101 has horizontally opened fixing grooves 1011 on both sides of its inner wall. The fixing grooves 1011 have longitudinally extended sliding grooves 1012 at both ends. Support plates 103 are installed in both the fixing grooves 1011 and the sliding grooves 1012. The fixing grooves 1011 are fixed to the support plates 103, and the sliding grooves 1012 are slidably connected to the support plates 103.

[0024] The support plates 103 on both sides are provided with a number of mounting holes 1031 in a corresponding array. The conveying rollers 102 are rotatably mounted through the mounting holes 1031. The shaft of the conveying roller 102 passes through the mounting holes 1031 on both sides of the support plates 103, and pulleys 1021 are fixed at both ends. All pulleys 1021 on the same side are of the same model and their axes are at the same height.

[0025] All pulleys 1021 on any side are fitted with belt 105, which drives all transmission rollers 102 to rotate.

[0026] A motor 106 is slidably connected to the inner wall of the base 101 on the same side as the belt 105. The output end of the motor 106 is coaxially fixed to a pulley 1061 through the side wall. The pulley 1061 is compatible with the pulley 1021, and the axis height of the pulley 1061 is lower than the axis height of the pulley 1021, so that the belt 105 forms a wrap angle ≥120°.

[0027] Conveying status: The motor 106 drives the pulley 1061 to rotate, which in turn drives all pulleys 1021 and conveyor rollers 102 to rotate synchronously via belt 105, thus realizing the horizontal conveying of objects.

[0028] A bearing 1062 is fixed between the pulley 1061 and the inner wall of the base 101. A telescopic rod 1063 is installed on the outer wall of the bearing 1062. The fixed end of the telescopic rod 1063 is fixed to the base 101, and the output end is fixed to the bearing 1062. The telescopic direction of the telescopic rod 1063 is consistent with the tensioning and slack direction of the belt 105.

[0029] A cylinder 104 is provided at the bottom of the support plate 103 inside the sliding groove 1012. The fixed end of the cylinder 104 is fixed to the base 101, and the output end is fixed to the bottom of the support plate 103 inside the sliding groove 1012.

[0030] Stop and Lifting State: When the object is transported to the designated position, the telescopic rod 1063 retracts, driving the motor 106 and pulley 1061 to move away from pulley 1021, causing the belt 105 to loosen initially; at the same time, the cylinder 104 extends, pushing the sliding side support plate to move longitudinally along the sliding groove 1012, driving all the conveyor rollers 102 and pulleys 1021 to move synchronously, causing the belt 105 to deviate from the meshing range of some pulleys 1021, so that all pulleys 1021 and conveyor rollers 102 within the lifting mechanism 2 range are completely disconnected from the transmission connection, and the conveyor rollers 102 stop rotating.

[0031] The lifting mechanism 2 includes several cylinders 201 fixed to the inner walls of both sides of the base 101. The cylinders 201 on both sides are alternately distributed and their output ends face the opposite side of the base 101 and are fixed with sliding blocks 202. The bottom of the sliding block 202 cooperates with the bottom inner wall of the base 101 through a linear guide rail to achieve smooth lateral sliding. The top of the sliding block 202 on the same side is fixed with a support plate 203. A shearing mechanism 3 is provided between the two support plates 203. The shearing mechanism 3 is a cross scissor structure. Its bottom ends are rotatably connected to the top hinge seats of the two support plates 203 on both sides. A synchronous guide shaft is provided at the intersection of the shearing mechanism 3 to ensure that the shearing action is synchronous, stable and without deviation.

[0032] The top of the shearing mechanism 3 is fixed with a lifting platform 301. The lifting platform 301 is a rectangular plate structure with several mounting grooves 3012 extending through its end face along the length direction. The number of mounting grooves 3012 corresponds one-to-one with the number of conveying rollers 102, and the width of the mounting grooves 3012 is greater than the outer diameter of the conveying rollers 102. The lifting platform 301 is located directly below the gap between the conveying rollers 102, and its lifting and sliding path corresponds perfectly with the distribution gap of the conveying rollers 102. This ensures that when the lifting platform 301 rises, the conveying rollers 102 can be accurately embedded in the mounting grooves 3012, avoiding mechanical interference and achieving stable support of objects.

[0033] The lifting platform 301 is equipped with vision sensors 3011 at both ends for observing objects. The lenses of the vision sensors 3011 are set upwards, and their detection range covers the top receiving surface of the lifting platform 301. When the object is transferred to the designated position, the vision sensors 3011 can collect the center offset of the object in real time and feed the data back to the control system to correct the lifting accuracy of the shear lifting mechanism 3 and the positioning reference of the subsequent transplanting action, so as to ensure the accurate transplanting position of the object.

[0034] The outer walls of the conveyor rollers 102 adjacent to both ends of the lifting platform 301 and the conveyor rollers 102 in the mounting groove 3012 are provided with a plurality of sliding grooves 302 arranged in a circular array. The inner wall of the sliding groove 302 is provided with a guide keyway. A pressure detection block 303 is slidably connected in the sliding groove 302. The outer wall of the pressure detection block 303 is provided with a guide protrusion adapted to the guide keyway, ensuring that the pressure detection block 303 can only move along the axial direction of the sliding groove 302 and does not rotate circumferentially. A limit block is provided at the bottom of the pressure detection block 303 to prevent the pressure detection block 303 from sliding out of the sliding groove 302 as a whole.

[0035] The bottom of the sliding groove 2 302 is coaxially provided with a detection groove 304. The inner diameter of the detection groove 304 is smaller than the inner diameter of the sliding groove 2 302, forming a stepped structure. A high-sensitivity sensor 305 is provided in the detection groove 304. The detection probe of the high-sensitivity sensor 305 faces the bottom end face of the pressure detection block 303 and is used to accurately detect the axial movement distance of the pressure detection block 303. The high-sensitivity sensor 305 is connected to a control system. The control system is electrically connected to the other motors 106, 107, 201, 1092, 1092, and 1063 to control the start and stop of the motors 106, 107, 201, 104, 1092, and 1063.

[0036] The bottom of the detection groove 304 is coaxially provided with a second mounting groove 306, and a spring 307 is fixed at the bottom of the second mounting groove 306. The other end of the spring 307 is fixed to the pressure detection block 303.

[0037] In its natural state, the spring 307 is in a slightly compressed state, pushing the top end face of the pressure detection block 303 to coincide with the outer wall of the conveyor roller 102 and be higher than the top end face of the lifting platform 301, ensuring that the object can directly contact the pressure detection block 303 when it is placed.

[0038] The inner wall of several of the mounting slots 306 is provided with annular ventilation channels 308 communicating with them; the annular ventilation channels 308 are used to balance the air pressure in the mounting slots 306: when the pressure detection block 303 moves downward, the overall pressure in the mounting slots 306 and the annular ventilation channels 308 increases and the pressure in the mounting slots 306 in the same conveyor roller 102 remains consistent.

[0039] When an object is placed on the conveyor roller 102 and transported to the top of the lifting platform 301, the object's weight acts on the top end face of the pressure detection block 303 on the outer wall of the conveyor roller 102. The pressure detection block 303, under the weight of the object, causes the compression spring 307 to move downward, thereby changing the pressure on the inner wall of the detection groove 304. At this time, the pressure detection block 303 in contact with the object is subjected to the pressure exerted by the object's weight, the spring force of the spring 307, and the pressure in the second mounting groove 306. Due to the resistance of the spring force of the spring 307 and the pressure exerted by the pressure in the second mounting groove 306 on the pressure detection block 303, the downward distance of the pressure detection block 303 under the weight of the object is relatively short. The overall deformation of the conveyor roller 102 is small, and the influence on the rotation of the conveyor roller 102 is not significant. However, the distance moved by the pressure detection block 303 can be detected by the high-sensitivity sensor 305. At this time, the high-sensitivity sensor 305 in the detection groove 304 will detect the displacement of the bottom end face of the pressure detection block 303 in real time, and convert the displacement data into an electrical signal and transmit it to the control system. The control system determines the center of gravity distribution of the object by comparing the displacement differences of the pressure detection blocks 303 on different conveyor rollers 102 that are in contact with the object.

[0040] A second motor 107 is fixed to the inner wall of the base 101. The second motor 107 is located on the side away from the first motor 106 and corresponds to the longitudinal position of the lifting platform 301. The second motor 107 passes through the side wall and is coaxially fixed to a third pulley 1071. The third pulley 1071 is compatible with the model of the first pulley 1021, and the axial height of the third pulley 1071 is lower than that of the first pulley 1021. The first pulley 1021 and the third pulley 1071 of the conveyor roller 102 at both ends of the lifting platform 301 and in the mounting groove 3012 are all fitted with a second belt 108, which is used to drive the local conveyor roller to rotate after the lifting is completed, in coordination with the transplanting action.

[0041] When an object is placed on the conveyor roller 102 and transported to the top of the lifting platform 301, and a shift in the center of gravity is detected, the engagement between pulley 1021, located in the mounting groove 3012 and the conveyor roller 102 adjacent to the lifting platform 301, and belt 108 is disengaged. Motor 107 is started, driving pulley 1071 to rotate, which in turn drives pulley 1021 of the conveyor roller 102 located at both ends of the lifting platform 301 and in the mounting groove 3012 via belt 108. This adjusts the position of the object's center of gravity, ensuring it is centered on the lifting platform 301, preventing the platform from tilting due to instability when carrying the object upwards.

[0042] Two mounting plates 109 are fixed to the bottom of the base 101. The two mounting plates 109 are located on both sides of the lifting mechanism 2. A connecting plate 110 is slidably connected between the two mounting plates 109. The connecting plate 110 has an arc-shaped groove 1103 adapted to the conveyor roller 102. In the conveying state, part of the connecting plate 110 on the conveyor roller 102 abuts against the inner wall of the arc-shaped groove 1103, restricting the sliding of the connecting plate 110. The edge of the arc-shaped groove 1103 is provided with a rounded chamfer to prevent the pressure detection block 303 from protruding and jamming the connecting plate 110 during the rotation of the conveyor roller 102. The interior of the shaped groove 1103 has several mounting slots 1104, and each mounting slot 1104 is equipped with a roller 1105. In the conveying state, the roller 105 is in contact with the outer wall of the conveying roller 102 to reduce the friction between the conveying roller 102 and the shaped groove 1103 when rolling. The end face of the connecting plate 110 has several through holes 1101. The through holes 1101 are adapted to the shearing mechanism 3. The position of the through holes 1101 corresponds to the distribution of the connecting rods of the shearing mechanism 3 to ensure that the shearing mechanism 3 can pass through the through holes 1101 when lifting and lowering without interfering with the connecting plate 110.

[0043] When the pressure inside the second mounting groove 306 increases, the pressure detection block 303, which is not in contact with the object, bulges outward under the pressure. Due to the resistance of the inner wall of the arc groove 1103, part of the pressure detection block 303 cannot slide, thereby stabilizing the internal pressure of the second mounting groove 306.

[0044] The two mounting plates 109 have mounting grooves 1091 on their side walls. A cylinder 1092 is fixed in the mounting groove 1091. The output end of the cylinder 1092 faces the connecting plate 110 and is fixed with a wedge block 1093. The wedge block 1093 is located below the connecting plate 110.

[0045] The bottom of the connecting plate 110 is provided with a chamfer 1102 that matches the wedge block 1093. The direction of the force of the cylinder 1092 is changed by the contact of the inclined surface: the horizontal thrust is converted into a vertical positioning force to achieve stable positioning of the connecting plate 110.

[0046] When cylinder 3 1092 extends, the inclined surface of wedge block 1093 fits against the chamfer 1102 of connecting plate 110. The inclined surface contact restricts the sliding of connecting plate 110, and at the same time converts the horizontal thrust of cylinder 3 1092 into a vertical preload on connecting plate 110, ensuring that connecting plate 110 does not shift during the support of conveyor roller 102.

[0047] Once the center of gravity of the object has been adjusted to the center of the lifting platform 301, the wedge block 1093 is moved toward the direction of the cylinder 1092 by controlling the cylinder. The connecting plate 110 moves downward under the action of gravity and can no longer restrict the pressure detection block 303, causing the pressure detection block 303 to slide and thus lower the pressure in the pressure mounting groove 306. As the pressure on the pressure detection block 303, which is in direct contact with the object, decreases, the pressure detection block 303 moves downward under the action of the object's gravity, causing the object to directly contact the sliding groove 302, changing from the original line contact to surface contact, preventing the conveyor roller 102 from rotating relative to each other and thus changing the center of gravity position of the object.

[0048] Working principle: When an object is placed on the conveyor roller 102, it is in the conveying state: The motor 106 drives the pulley 1061 to rotate, which in turn drives all the pulleys 1021 and the conveyor roller 102 to rotate synchronously via the belt 105, thus realizing the horizontal transport of the object.

[0049] In position detection mode: When the object is transferred to the shearing mechanism 3, the vision sensor 3011 can collect the center offset of the object on both sides relative to the lifting platform 301 in real time and feed the data back to the control system to correct the lifting accuracy of the shearing mechanism 3 and the positioning reference of the subsequent transplanting action, so as to ensure the accurate transplanting position of the object.

[0050] In the pressure detection state: After the position detection is completed, the gravity of the object will act on the top end face of the pressure detection block 303 on the outer wall of the conveyor roller 102. The pressure detection block 303 is subjected to the gravity of the object, causing the compression spring 307 to move downward, thereby changing the pressure on the inner wall of the detection groove 304. At this time, the pressure detection block 303 in contact with the object is subjected to the pressure exerted by the gravity of the object, the elastic force of the spring 307, and the pressure in the second mounting groove 306. Due to the resistance of the elastic force of the spring 307 and the pressure exerted by the pressure in the second mounting groove 306 on the pressure detection block 303, the downward distance of the pressure detection block 303 under the gravity of the object is relatively short. The overall deformation of the conveyor roller 102 is small, and the influence on the rotation of the conveyor roller 102 is not significant. However, the distance moved by the pressure detection block 303 can be detected by the high-sensitivity sensor 305.

[0051] The high-sensitivity sensor 305 inside the detection groove 304 detects the displacement of the bottom end face of the pressure detection block 303 in real time and converts the displacement data into an electrical signal, which is then transmitted to the control system. The control system determines the center of gravity distribution of the object by comparing the displacement differences of the pressure detection blocks 303 on different conveyor rollers 102 that are in contact with the object.

[0052] Under normal circumstances, when the object is located at the set center offset position, its center of gravity is located at the center of the lifting platform 301. If the center is detected to be outside the center of the lifting platform 301, it indicates that the object is defective.

[0053] In the state of center of gravity adjustment: When the object is conveyed to the top of the lifting platform 301 and a shift in the center of gravity is detected, the engagement between pulley 1021, which is located in the mounting groove 3012 and the conveyor roller 102 adjacent to the lifting platform 301, and belt 108 is disconnected. Motor 107 is started, which drives pulley 1071 to rotate and, through belt 108, drives pulley 1021 of the conveyor roller 102 located at both ends of the lifting platform 301 and in the mounting groove 3012 to rotate, thereby adjusting the position of the object's center of gravity so that the object's center of gravity is located in the center of the lifting platform 301, preventing the lifting platform 301 from tilting due to instability when it carries the object upwards.

[0054] In the lifting state: Cylinder 201 retracts, pushing sliding block 202 to slide smoothly laterally along the linear guide rail, thereby moving support plate 203. Since the bottom ends of shearing mechanism 3 are rotatably connected to the top hinge seats of support plate 203 on both sides, the shearing mechanism 3 achieves synchronous, stable, and offset shearing action during the movement of support plate 203, lifting platform 301. When platform 301 rises, conveyor roller 102 is located within mounting groove 3012, avoiding mechanical interference and ensuring stable material reception. The shearing height differs between qualified and defective items to separate qualified and defective products.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
