Description

Technical fields:

[0001] This invention relates to the field of intelligent transmission system technology, and specifically to a magnetic levitation transmission system and its charging and discharging method. Background technology:

[0002] Conveying systems are essential in production lines and conveyor belts, but early systems like belt conveyors and screw conveyors are no longer sufficient for modern industrial needs. To address this, magnetic levitation conveying systems are being used in some industries. In a magnetic levitation conveying system, the moving module runs on a stator track, propelled by electromagnetic force for high-speed and precise operation. For example, Chinese Utility Model Patent No. 202322746727.1 discloses "A Planar Circular Magnetic Levitation Conveying Line." The applicant has been dedicated to the research and development of magnetic levitation conveying systems and has filed relevant patent applications. See Utility Model Patent No. 202323139809.6, entitled "A Circular Track Conveying System"; and Utility Model Patent No. 202323144537.9, entitled "A Conveying Track Structure."

[0003] In existing magnetic levitation or linear motor transmission systems, the moving module not only serves as a carrier for material transport, but in some industries, it also carries electric equipment to perform corresponding operations at designated workstations. In this case, the moving module needs its own power supply capability. To achieve this, it can only be achieved through an internal energy storage battery or a direct external power supply. However, considering the moving module's operating speed, accuracy, and distance, direct wire power supply is impractical. Using carbon brush sliding contact power supply presents the following problems: the moving module typically operates in an open environment, inevitably containing dust and other foreign objects. With carbon brush sliding contact power supply, due to direct contact, it may be affected by dust and other foreign objects in the working space, leading to poor contact or even sparking, seriously impacting safety. If the moving module is powered by its own energy storage battery, the battery has a limited capacity and needs charging. During charging, the electric equipment on the moving module cannot operate; leaving it on the track would affect the normal operation of other moving modules. Removing the entire moving part module for charging would be too inconvenient.

[0004] In response to the above problems, the inventors have made continuous improvements and proposed the following technical solutions. Summary of the Invention:

[0005] The first technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a magnetic levitation transmission system.

[0006] The second technical problem to be solved by the present invention is to propose a method for charging and discharging the energy storage unit in the moving vehicle in combination with the above-mentioned magnetic levitation transmission system.

[0007] To solve the first technical problem mentioned above, the present invention adopts the following technical solution: a magnetic levitation transmission system, comprising: a magnetic levitation transmission track, a magnetic levitation charging track, a left lifting device, a right lifting device, a sliding charging device, and a moving vehicle; the magnetic levitation transmission track is formed by splicing together an independent main track segment and left and right track segments located on both sides of the main track segment, and stator units for generating magnetic force are respectively arranged in the main track segment, the left track segment, and the right track segment; the magnetic levitation charging track is of the same length as the main track segment and is arranged parallel to it below the main track segment, and stator units for generating magnetic force are arranged in the magnetic levitation charging track; the left lifting device and the right lifting device are respectively vertically located at the left and right ends of the main track segment, and the left lifting device and the right lifting device are respectively equipped with Y-shaped... The system includes a left and right lifting platform that moves along the axial direction. The left and right track segments are fixedly mounted on the left and right lifting platforms, respectively. The left and right track segments are raised and lowered via left and right lifting devices, allowing them to connect with the main track segment and the magnetic levitation charging track, respectively. The moving vehicle includes a moving base, an energy storage unit mounted on the moving base, and a moving magnet. The magnetic force generated by the stator unit interacts with the moving magnet to propel the moving vehicle along the magnetic levitation transmission track or the magnetic levitation charging track along the X-axis. A sliding charging device is arranged parallel to the side of the magnetic levitation charging track and has a conductive strip that provides charging power. When the moving vehicle runs on the magnetic levitation charging track, the energy storage unit is slidably connected to the conductive strip via a current collector, thus charging the energy storage unit.

[0008] Furthermore, in the above technical solution, the magnetic levitation transmission track and the magnetic levitation charging track are equipped with guide tracks of the same specifications; the lower end of the moving base is equipped with a guide seat or guide wheel that matches the guide track.

[0009] The main track segment is installed on the transverse module, which includes: a transverse track perpendicular to the main track segment, a transverse seat cooperating with the transverse track, and a transverse drive motor that drives the transverse seat to run along the transverse track. The main track segment is fixed on the transverse seat to achieve movement in the Z-axis direction.

[0010] Furthermore, in the above technical solution, the transverse module is equipped with two sets of parallel main track sections.

[0011] Furthermore, in the above technical solution, the left lifting device includes: a vertically erected lifting rail, a longitudinal shifting seat that cooperates with the lifting rail, and a longitudinal drive motor that drives the longitudinal shifting seat to run along the lifting rail, wherein the left lifting platform is horizontally fixed on the longitudinal shifting seat.

[0012] Furthermore, in the above technical solution, the right lifting device and the left lifting device have the same structure, and the right lifting device and the left lifting device are symmetrically distributed at the left and right ends of the main track section.

[0013] Furthermore, in the above technical solution, the current collector includes: a substrate and two sets of conductive sliding contact units mounted on the substrate. The substrate is connected to the mover base through a connecting plate. The conductive sliding contact unit has a conductive brush connected to the substrate through an elastic movable linkage mechanism. The energy storage unit is connected to the conductive brush through a wire.

[0014] Furthermore, in the above technical solution, the sliding contact charging device includes: two parallel conductive strips, a conductive groove, and a conductive groove fixing seat corresponding to the two sets of conductive sliding contact units. The conductive strips are fixed in the conductive grooves and are connected to an external power source. The conductive grooves are fixed to a fixing plate by the conductive groove fixing seat. The conductive brush is elastically pressed against the conductive grooves and makes conductive contact with the conductive strips.

[0015] Furthermore, in the above technical solution, the conductive sliding contact unit includes: a conductive brush, a connecting pin, a swing arm, and a connecting seat. The swing arm is elastically pivotally connected to the connecting seat, and the swing end of the swing arm is slidably connected to the connecting pin through a shaft hole. A compression spring is sleeved on the connecting pin. The conductive brush is pivotally connected to the end of the connecting pin.

[0016] To solve the second technical problem mentioned above, the present invention adopts the following technical solution: a charging and discharging method for a magnetic levitation transmission system, wherein the charging and discharging method is as follows: the moving vehicle generates magnetic force through the stator unit and interacts with the moving magnet, running along the magnetic levitation transmission track to realize the transmission of the moving vehicle, and during the passage, it discharges through the energy storage unit to supply power to the electrical equipment carried on the moving vehicle; during charging, firstly, the moving vehicle runs to the left track segment position and descends to a position level with the magnetic levitation charging track through the left lifting device; secondly, the energy storage unit on the moving vehicle is connected to the conductive strip through the current collector to realize the charging of the energy storage unit; then, while charging or after charging is completed, the moving vehicle runs towards the right track segment under the drive of the magnetic levitation charging track until it runs to the right track segment that has already descended with the right lifting device; finally, the energy storage unit is disconnected from the current collector, and the moving vehicle rises with the right track segment under the drive of the right lifting device, realizing the reconnection of the right track segment with the main track segment.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0018] 1. In the magnetic levitation transmission system of the present invention, a magnetic levitation charging track is arranged parallel below the magnetic levitation transmission track used for transmission. The moving vehicle realizes displacement transmission through the magnetic levitation transmission track. When the moving vehicle needs to be charged, it switches to the magnetic levitation charging track through the left and right lifting devices. In this way, the normal operation of the upper magnetic levitation transmission track is not affected, and the charging operation of the moving vehicle with insufficient power can be completed, further improving the working efficiency of the magnetic levitation transmission system.

[0019] 2. The magnetic levitation charging track of the present invention is located below the magnetic levitation transmission levitation track. In this way, during equipment installation, the magnetic levitation charging track can be installed in a relatively enclosed manner inside the equipment housing. The entire charging operation is in a relatively enclosed space, which avoids the sliding contact charging device from coming into contact with foreign objects such as dust in the open space during the charging operation, reduces charging interference, and improves charging safety.

[0020] 3. The moving vehicle in this invention has a built-in energy storage unit, which directly supplies power to the relevant electric equipment mounted on the moving vehicle, further enhancing the functionality of this invention and making it applicable to more work scenarios with a wider range of uses.

[0021] 4. This invention adopts a modular design, which can be combined and spliced ​​as needed to adapt to different work requirements. Attached image description:

[0040] This invention relates to a magnetic levitation transmission system, see [link / reference]. Figures 1 to 3 As shown, the present invention includes: a magnetic levitation transmission track 1, a magnetic levitation charging track 2, a left lifting device 5, a right lifting device 6, a current collector 7, a sliding contact charging device 8, and a moving carrier 9.

[0041] The magnetic levitation transmission track 1 and magnetic levitation charging track 2 are arranged parallel to each other, with the transmission track 1 above and the charging track 2 below. A left lifting device 5 and a right lifting device 6 are located on the left and right sides of the magnetic levitation transmission track 1 and the charging track 2, respectively. The moving vehicle 9 runs on the magnetic levitation transmission track 1 and the charging track 2 to achieve transmission or charging. Simultaneously, the left lifting device 5 and the right lifting device 6 switch between the magnetic levitation transmission track 1 and the charging track 2. A sliding charging device 8 is located parallel to the side of the charging track 2. When the moving vehicle 9 runs on the charging track 2, it can achieve a conductive connection with the sliding charging device 8 through the current collector 7, thereby charging the moving vehicle 9.

[0042] In this invention, the drive between the moving vehicle 9 and the magnetic levitation transmission track 1 and the magnetic levitation charging track 2 is electromagnetically driven. Specifically, stator units that generate magnetic force are evenly distributed within the magnetic levitation transmission track 1 and the magnetic levitation charging track 2. Hall effect elements are installed beside each set of stator units to determine the running direction of the moving vehicle 9. Under the action of an external power source, the stator units generate electromagnetic force, which interacts with the magnets in the moving vehicle 9, propelling the moving vehicle 9 along the track, thus realizing the electromagnetic force driving the moving vehicle 9. This magnetic levitation drive principle and structure are the same as those in existing technologies; for example, existing patent documents in the background art can be referred to, and will not be repeated here.

[0043] Combination Figure 4 As shown, the magnetic levitation transmission track 1 is formed by splicing together an independent main track segment 10 and two side track segments 3 and 4 located on either side of the main track segment 10. That is, the main track segment 10, the left track segment 3, and the right track segment 4 are independently constructed stator tracks, each containing a stator unit for generating magnetic force and related Hall elements. In this way, the mover vehicle 9 can operate independently on the main track segment 10, the left track segment 3, and the right track segment 4.

[0044] Combination Figure 4 As shown, the moving vehicle 9 includes: a moving base 91, an energy storage unit 92 mounted on the moving base 91, an electric component 93, a control circuit 94, and a moving magnet (not shown) located below the base 91. The energy storage unit 92 is typically a rechargeable battery pack, which powers the electric component 93 and the control circuit 94. The electric component 93 is a working motor or similar component, and the control circuit 94 can be a control circuit with a built-in communication module, enabling remote control of the electric component 93. In this way, the moving vehicle 9 can function as a mobile workstation, moving to a designated location to perform relevant operations.

[0045] Combination Figure 2 As shown, the magnetic levitation charging track 2 is the same length as the main track segment 10 and is arranged parallel to the main track segment 10 below it. This is to facilitate the splicing and combination of the left track segment 3, the right track segment 4, the magnetic levitation charging track 2, and the main track segment 10.

[0046] Combination Figure 4 , Figure 13As shown, to ensure stable operation of the moving vehicle 9 on the magnetic levitation transmission track 1 and the magnetic levitation charging track 2, a track-type mating structure is adopted between the moving vehicle 9 and the magnetic levitation transmission track 1 and the magnetic levitation charging track 2. Slide rail sleeves 911 are symmetrically arranged on both sides of the base 91 of the moving vehicle 9. Both the magnetic levitation transmission track 1 and the magnetic levitation charging track 2 are equipped with two parallel guide rails 101 and 201 of the same specifications. The slide rail sleeves 911 are nested and fitted with the guide rails 101 and 201, allowing the slide rail sleeves 911 to slide along the guide rails 101 and 201. Of course, the slide rail sleeves 911 can also be guide wheels.

[0047] The left lifting device 5 and the right lifting device 6 have the same structure and are symmetrically distributed on the left and right sides of the main track 1 and the magnetic levitation charging track 2. The following description focuses on the left lifting device 5.

[0048] The left lifting device 5 includes: a vertically erected lifting rail 51, a longitudinal sliding seat 52 cooperating with the lifting rail 51, and a longitudinal driving motor 53 driving the longitudinal sliding seat 52 to run along the lifting rail 51. The lifting rail 51 and the longitudinal driving motor 53 are fixedly installed on the upright plate 510 or column. The left lifting platform 50 is horizontally fixed on the longitudinal sliding seat 52. The lifting rail 51 and the longitudinal sliding seat 52 adopt a sliding rail and sliding sleeve cooperation structure. The longitudinal driving motor 53 can use a lead screw drive mechanism, belt drive mechanism, chain drive mechanism, etc. to drive the longitudinal sliding seat 52 to run vertically. The left track segment 3 is fixedly installed on the horizontal left lifting platform 50. The left track segment 3 is spliced ​​with the main track segment 10 and the magnetic levitation charging track 2 by the up and down movement of the left lifting platform 50.

[0049] In addition, to achieve vertical positioning of the longitudinal sliding seat 52, a sensing element 54 or a positioning element can be added to ensure accurate alignment of the left track segment 3 with the main track segment 10 and the magnetic levitation charging track 2. The left track segment 3 and right track segment 4 are respectively fixedly installed on the left lifting platform 50 and the right lifting platform 60. The left lifting device 5 and the right lifting device 6 drive the left track segment 3 and right track segment 4 to rise and fall, thereby connecting the left track segment 3 and right track segment 4 with the main track segment 10 and the magnetic levitation charging track 2 respectively. The right lifting device 6 has the same structure as the left lifting device 5, and will not be described further here.

[0050] As can be seen from the above description, in this invention, the magnetic levitation charging track 2 is located below the magnetic levitation transmission track 1. This ensures the normal operation of the upper magnetic levitation transmission track 1 while simultaneously enabling the charging of the powered carrier 9, further improving the working efficiency of the magnetic levitation transmission system. For example, when it is found that a carrier 9 operating on the magnetic levitation transmission track 1 is low on power and needs charging, the carrier 9 is moved to the left track segment 3. Then, the left lifting device 5 lowers the left track segment 3 to separate it from the main track segment 10 and connect it with the magnetic levitation charging track 2. The carrier 9 is then pushed onto the magnetic levitation charging track 2 for charging. After charging is complete, it is raised again by the right lifting device 4 and returns to the magnetic levitation transmission track 1 to continue operation. Simultaneously, the magnetic levitation charging track 2 is located below the magnetic levitation transmission track 1, allowing it to be relatively enclosed within the equipment housing during installation. The entire charging operation is conducted in a relatively enclosed space, reducing charging interference and improving charging safety.

[0051] The structure described above enables the normal operation and charging of the moving vehicle 9 in this invention. However, at certain times, a section of the main track 10 may malfunction and require maintenance, necessitating the shutdown of the entire system and rendering it inoperable. Furthermore, in some operational scenarios, the moving vehicle 9 may need to stop at a certain location for operation. In this case, the stopped moving vehicle 9 would affect the normal operation of other moving vehicles 9, requiring avoidance maneuvers. Therefore, this invention includes a lateral movement module 11.

[0052] See Figure 5 , Figure 6 , Figure 7 As shown, a section of the main track 10 in this invention can be installed on a transverse module 11. The transverse module 11 includes: a transverse track 111 that is vertically distributed along the horizontal plane with the main track 10, a transverse seat 112 that cooperates with the transverse track 111, and a transverse drive motor 113 that drives the transverse seat 112 to run along the transverse track 111.

[0053] The transverse track 111 is fixedly mounted on the transverse fixing plate 110, which enables the entire transverse module 11 to be positioned within the system. The main track segment 10 is fixed on the transverse seat 112, enabling overall horizontal movement. In this embodiment, the main track segment 10 is mounted on two parallel transverse tracks 111. The transverse seat 112 and the transverse track 111 are typically connected by a slide rail and a sliding sleeve. The transverse drive motor 113 can use a screw drive mechanism, belt drive mechanism, chain drive mechanism, etc., to drive the transverse seat 112 to move horizontally, thereby separating the main track segment 10 from the original magnetic levitation transmission track 1.

[0054] Of course, to avoid affecting normal operation, the transverse module 11 is equipped with two sets of parallel main track sections 10. These two sets of parallel main track sections 10 can be switched through the transverse module 11 to dock with the magnetic levitation transmission track 1. In this way, when the current main track section 10 malfunctions, or when the moving vehicle 9 needs to operate at that position, the other main track section 10 can be switched through the transverse module 11, thereby ensuring that the entire system can continue to operate.

[0055] For ease of explanation, combined with Figure 1 , Figure 2 As shown in this specific embodiment, Figure 1 The horizontal direction in the diagram is the X-axis, and the vertical direction is the Y-axis. Figure 2 The transverse direction is the Z-axis. The moving vehicle 9 moves along the magnetic levitation transmission track 1 or the magnetic levitation charging track 2 in the X-axis direction. The left lifting device 5 and the right lifting device 6 can drive the moving vehicle 9 to move along the Y-axis. The main track section 10 is fixed on the transverse sliding seat 112, realizing movement of the entire main track section 10 in the Z-axis direction.

[0056] See Figures 8 to 13 As shown, the sliding charging device 8 is arranged parallel to the side of the magnetic levitation charging track 2. It has a conductive strip 80 that provides charging power. When the moving vehicle 9 runs on the magnetic levitation charging track 2, the energy storage unit 92 is slidably connected to the conductive strip 80 through the current collector 7, thus charging the energy storage unit 92. Specifically, the sliding charging device 8 includes: a conductive strip 80, a conductive groove 81, a conductive groove fixing seat 82, and a fixing plate 83. The fixing plate 83 is a fixed bearing component, which is arranged vertically parallel to the side of the magnetic levitation charging track 2. Two parallel conductive grooves 81 are fixed to the inner side of the fixing plate 83 by the conductive groove fixing seat 82. The conductive groove fixing seat 82 adopts a clamping and fixing structure, and the entire conductive groove 81 is fixed to the fixing plate 83 by a number of conductive groove fixing seats 82. The conductive groove 81 is usually made of ceramic or other insulating materials, and it has a V-shaped or similar groove. The conductive strip 80 is fixed in the conductive groove 81. The conductive strip 80 is usually made of copper. The conductive strips 80 in the two conductive grooves 81 serve as the positive and negative terminals of the power supply, respectively, and are connected to the external power supply through the wires 84, thereby forming charging electrodes.

[0057] See Figures 13 to 17As shown, the current collector 7 includes a base plate 71 and two sets of conductive sliding contact units 70 mounted on the base plate 71. The base plate 71 is connected to the mover base 91 via a connecting plate 72, which can be fixed with screws. Of course, for quick assembly, the connecting plate 72 can be connected by snap-fit, strong magnetic adsorption, or other methods. When the mover carrier 9 is transported to the magnetic levitation charging track 2, the mover carrier 9 is connected to the current collector 7 via the connecting plate 72, and the charging connection line of the energy storage unit 92 in the mover carrier 9 is connected to the conductive brushes of the two conductive sliding contact units 70 via wires, awaiting charging operation.

[0058] The conductive sliding contact unit 70 has a conductive brush 73 connected to the base plate 71 via an elastic movable linkage mechanism, and the energy storage unit 92 is connected to the conductive brush 73 via a wire. The elastic movable linkage mechanism can overcome adverse conditions such as jumping and displacement deviation during operation, ensuring stable connection between the conductive brush 73 and the conductive strip 80 in the sliding contact charging device 8.

[0059] Specifically, two conductive sliding contact units 70 are horizontally parallel to each other on the outer surface of the substrate 71. Each conductive sliding contact unit 70 includes a conductive brush 73, a connecting pin 74, a swing arm 75, and a connecting seat 76. The connecting seat 76 is fixed to the outer surface of the substrate 71 by a connecting bolt 77. At the same time, the connecting bolt 77 also serves as a component for connecting to the connecting plate 72. The connecting plate 72 is fixed to the substrate 71 by the cooperation of the nut and the connecting bolt 77.

[0060] The connecting seat 76 has a pair of ear plates formed on one side. The swing arm 75 is elastically pivotally connected between the two ear plates of the connecting seat 76, realizing swinging along the pivot position 750. One end of the swing arm 75 is provided with a limiting plate 752, and the other end is used to connect with the connecting pin 74. The limiting plate 752 is used to limit the swing amplitude of the swing arm 75. At the same time, a wire positioning ring 753 is provided on the outside of the limiting plate 752. The charging connection wire connecting the energy storage unit 92 and the conductive brush 73 passes through the wire positioning ring 753 to realize the positioning of the charging connection wire.

[0061] A compression spring 751 is provided between the swing arm 75 and the connecting seat 76. The compression spring 751 applies a certain elastic force to the swing arm 75, thereby causing the end connected to the connecting pin 74 to tend to move towards the sliding charging device 8. The compression spring 751 is installed by providing receiving grooves that can cooperate with both ends of the compression spring 751 on the inner side of the connecting seat 76 and in the middle of the swing arm 75, thereby limiting both ends of the compression spring 751.

[0062] The swing arm 75 is slidably connected to the connecting pin 74 at one end, which is formed with a pin hole 754. The upper end of the pin hole 754 is a wedge-shaped groove 755.

[0063] A compression spring 741 is fitted onto the connecting pin 74. One end of the connecting pin 74 is formed with a limiting cap 742, and the other end is provided with a pivot portion 743 for connection with the conductive brush 73. The limiting cap 742 is wedge-shaped and mates with the groove 755. The connecting pin 74 and the pin hole 754 are in a sliding fit. Under the elastic force of the compression spring 741, the limiting cap 742 is pressed tightly into the groove 755. At the same time, because the limiting cap 742 and the groove 755 adopt a wedge-shaped nested fit, the connecting pin 74 can be quickly reset even if it rotates along its axis.

[0064] The conductive brush 73 is typically a carbon brush, fixed to a brush holder 731. The brush holder 731 has a pivot position 730 for pivotally engaging with the pivot portion 743, and a wiring slot 732 for connecting the charging cable. The charging cable connecting the energy storage unit 92 and the conductive brush 73 is ultimately connected to the wiring slot 732, thus enabling the entire charging circuit to conduct.

[0065] The present invention achieves stable conductive contact through the current collector 7, thereby enabling the energy storage unit 92 to be connected to the conductive brush 73 through the wire, and can overcome adverse situations such as jumping and displacement deviation during operation, ensuring stable connection between the conductive brush 73 and the conductive strip 80 in the sliding charging device 8.

[0066] Based on the above description, the charging and discharging method of the magnetic levitation transmission system adopted in this invention is as follows: the moving vehicle generates magnetic force through the stator unit and interacts with the moving magnet to run along the magnetic levitation transmission track, thereby realizing the transmission of the moving vehicle. During the passage, the energy storage unit discharges to supply power to the electrical equipment carried on the moving vehicle. During charging, firstly, the moving vehicle 9 runs to the position of the left track segment 3 and descends to the position flush with the magnetic levitation charging track 2 through the left lifting device 5.

[0067] Secondly, the moving vehicle 9 is connected to the current collector 7 to achieve synchronous operation of the moving vehicle 9 and the current collector 7. The energy storage unit 92 is connected to the conductive brush 73 of the current collector 7 through the charging wire to achieve sliding contact with the conductive strip 80, thereby charging the energy storage unit 92.

[0068] Then, while charging or after charging is completed, the moving vehicle 9 moves towards the right track section 4 under the drive of the magnetic levitation charging track 2 until it reaches the right track section 4, which has already descended with the right lifting device 6.

[0069] Finally, the current collector 7 is separated from the moving vehicle 9, thus disconnecting the circuit between the energy storage unit 92 and the current collector 7. The moving vehicle 9 rises with the right track section 4 under the drive of the right lifting device 6, so that the right track section 4 can be spliced ​​with the main track section 10 again. The moving vehicle 9, which has completed charging, returns to the magnetic levitation transmission track 1 to carry out the corresponding transmission operation.

[0070] See Figure 18 The diagram shown is a perspective view of the invention in use. In practical applications, the invention is mounted on a base 11a. The magnetic levitation transmission track 1, the magnetic levitation charging track 2, the left lifting device 5, the right lifting device 6, and the sliding charging device 8 are assembled using profiles to form a magnetic levitation transmission unit 1a. Several magnetic levitation transmission units 1a can be combined to form a magnetic levitation transmission line.

[0071] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present invention should be included in the scope of the claims of the present invention.
