Description

Technical Field

[0001] This invention belongs to the field of transfer machine technology, specifically an ultra-thin pallet transfer machine. Background Technology

[0002] The ultra-thin pallet transfer machine is used in pallet conveying systems at workstations that require lifting and transferring. It is a special equipment used in conjunction with a chain conveyor to lift the pallet to be transferred to a certain height and then transfer the pallet in a 90-degree direction, realizing the 90-degree transfer and reversal function in the pallet conveying system. It is widely used in high-cleanliness scenarios such as electronics, pharmaceuticals, and food.

[0003] A Chinese patent with publication number CN222743532U discloses a pallet transfer machine, including a transverse conveying mechanism and a longitudinal conveying mechanism. The transverse conveying mechanism includes a transverse conveying frame and multiple sets of rollers, and the longitudinal conveying mechanism includes a base frame and multiple machine bodies. The longitudinal conveying frame is fixedly mounted on the top of the base frame, and the machine bodies are fixed to the top of the longitudinal conveying frame. A conveyor belt is mounted on the machine bodies, and four sets of hydraulic cylinders are arranged between the base frame and the longitudinal conveying frame. This device, through its designed limiting components, facilitates the installation of side plates and ball bearings near the right side of the transfer machine to block palletized items during use. When palletized items tend to continue moving to the right due to their own inertia, they contact the ball bearings on the side plates, blocking and limiting the palletized items. This allows the longitudinal conveying mechanism to rise and transport the palletized items towards the back of the transfer machine, improving the transfer efficiency of the palletized items.

[0004] When existing ultra-thin pallet transfer machines are used for reversing pallet transport, it is difficult to accurately adjust the pallet angle. They can only achieve simple reversing transport. After the reversal is completed, the system has poor compatibility. When moving the pallet to the next workstation, manual intervention may be required, which affects work efficiency and production efficiency.

[0005] To address the above problems, the present invention provides an ultra-thin pallet transfer machine. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies and solve the problem of inconvenient pallet angle adjustment, this invention proposes an ultra-thin pallet transfer machine.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides an ultra-thin pallet transfer machine, including a frame, a conveying mechanism for conveying pallets is provided on the frame, a limiting mechanism is provided on the frame, a square frame is fixedly provided inside the frame, a load-bearing plate is provided inside the square frame, strip plates are arranged in an array on the load-bearing plate, and the top of the strip plates penetrates through the square frame, a concave frame is fixedly provided on the top of the strip plates, an electric telescopic rod is fixedly provided inside the square frame, and the telescopic end of the electric telescopic rod is fixedly connected to the bottom of the load-bearing plate, and a moving mechanism is provided on the concave frame;

[0008] The concave frame has a support block inside, and the support block has an annular groove inside. An annular block is rotatably mounted inside the annular groove. A rubber ring is mounted on the top of the annular block. An adjustment plate is fixedly connected to the bottom of the support block. A gear ring is embedded in the bottom of the annular block. The support block has a drive mechanism inside for driving the annular block to rotate.

[0009] By adopting the above scheme, when using an ultra-thin pallet transfer machine to transfer ultra-thin pallets, after the frame is fixed to the assembly line with bolts, the ultra-thin pallet moves onto the frame and is then conveyed by a conveyor mechanism. A limiting mechanism is used to limit the position of the ultra-thin pallet. Then, controlling the electric telescopic rod will push the load-bearing plate to move. The movement of the load-bearing plate, through the cooperation of the strip plate and the concave frame, will drive the moving mechanism. The movement of the moving mechanism can change the direction of pallet movement. When changing the direction of pallet movement and adjusting the angle of the pallet for transfer, the position of the concave frame is adjusted to lift the pallet, and then... The telescopic push rod moves to adjust the height of the adjusting plate, which in turn adjusts the height of the support block. When the support block moves, it causes the ring block to move upward. After the top of the ring block contacts the bottom of the pallet, it limits the position of the pallet. Then, the drive mechanism, in conjunction with the gear ring, drives the ring block to rotate. When the ring block rotates, it adjusts the angle of the pallet. After the pallet is adjusted to the predetermined angle, the support block returns to its original position and no longer limits the position of the pallet. Then, the moving mechanism is controlled to transfer the pallet, which improves the flexibility of the ultra-thin pallet transfer machine, not only increasing production efficiency but also reducing manual intervention and improving compatibility.

[0010] Preferably, the strip plate has a storage groove inside, and a telescopic push rod is fixedly installed inside the storage groove. The telescopic end of the telescopic push rod is fixedly connected to the bottom end of the adjustment plate. The square frame has a limiting groove corresponding to the strip plate inside, and the strip plate passes through the limiting groove.

[0011] By adopting the above scheme, when adjusting the height of the support block, the telescopic push rod is controlled to adjust the height of the corresponding adjustment plate. When the adjustment plate moves, the height of the support block is adjusted. When the height of the support block is adjusted, the pallet can be lifted by the ring block. The operation of the electric telescopic rod will push the load-bearing plate to move. When the load-bearing plate moves, it will drive the strip plate to slide inside the limiting groove. The limiting groove will limit and guide the strip plate, so that the strip plate moves smoothly.

[0012] Preferably, the drive mechanism includes a support frame, a drive gear, and a second power motor. The support frame is fixedly installed inside the support block, the drive gear meshing with the gear ring is rotatably installed inside the support frame, and the second power motor that causes the drive gear to rotate is fixedly installed inside the support frame.

[0013] By adopting the above scheme, after the annular block lifts the tray, it controls the No. 2 power motor to work, driving the drive gear to rotate. The drive gear and the gear ring cooperate to make the annular block rotate, and the rotation of the annular block will adjust the angle of the tray.

[0014] Preferably, the conveying mechanism includes a protective cover, a conveying roller, a sprocket, a reducer, and a stepper motor. The protective cover is fixedly installed inside the frame, the conveying roller array is installed inside the frame, the sprocket is fixedly installed on the conveying roller, and adjacent sprockets are connected by chain drive. The reducer and the stepper motor are fixedly installed on the side of the frame, and the output end of the stepper motor is connected to the input end of the reducer. The output end of the reducer is connected to the corresponding sprocket drive.

[0015] By adopting the above scheme, when the stepper motor works, it will cause the reducer to move. The output end of the reducer is also connected to a sprocket. The sprocket is connected to the chain drive, so when the reducer moves, it will drive the sprocket to move. The sprocket will drive the conveyor roller to rotate, and the pallet can be conveyed through the conveyor roller.

[0016] Preferably, the limiting mechanism includes a mounting plate, an electric push rod, and a push plate. The mounting plate is fixedly installed inside the frame and is located on one side of the conveyor roller. The electric push rod is fixedly installed on the mounting plate, and the telescopic end of the electric push rod is fixedly connected to the push plate. A conveying pipe is provided on the square frame, and a diversion groove is embedded inside the push plate. Air jet holes are arrayed on the diversion groove.

[0017] By adopting the above scheme, the electric push rod will push the push plate to move. When the push plate moves, it will push the position of the pallet on the conveyor roller to move, thereby adjusting the position of the pallet. A silicone ring is set around the load-bearing plate and fits against the inner wall of the square frame. When the load-bearing plate moves up, it will compress the air above the square frame. The compressed air will flow into the conveying pipe and then into the diversion groove through the conveying pipe. Through the air jet hole, the air will flow to one side of the pallet surface, thereby cleaning the pallet surface and ensuring the cleanliness of the conveyed pallet.

[0018] Preferably, the moving mechanism includes a conveyor belt and a No. 1 motor. The conveyor belt is disposed inside the concave frame, and the No. 1 motor corresponding to the conveyor belt is fixedly disposed on the side of the concave frame, and the output end of the No. 1 motor is connected to the corresponding conveyor belt for transmission.

[0019] By adopting the above scheme, when the concave frame moves upward, the pallet is lifted by the conveyor belt, and the operation of motor number one will cause the conveyor belt to rotate. When the conveyor belt moves, the pallet will move, thereby changing the direction of the pallet's movement to transport materials, which improves flexibility.

[0020] Preferably, the annular block has a negative pressure groove inside, a connector is fixedly installed at the bottom center of the annular block and the connector is located at the center of the gear ring, the annular block has a circular hole inside and the two ends of the circular hole are respectively connected to the negative pressure groove and the connector, and sealing rings are symmetrically installed on the connector.

[0021] By adopting the above scheme, after the annular block lifts the tray, it fits against the bottom of the tray through the rubber ring. Through the cooperation of the connector and the round hole, the air inside the negative pressure groove is extracted, creating negative pressure inside the negative pressure groove, which can then limit the position of the tray.

[0022] Preferably, the annular block is surrounded by a circular groove, and a limiting ring is rotatably provided inside the circular groove, with the outer ring of the limiting ring being fixedly connected to the inner wall of the annular groove.

[0023] By adopting the above scheme, the rotation of the ring block will drive the rotation of the limiting ring. Through the cooperation of the circular groove and the limiting ring, the ring block will rotate smoothly.

[0024] Preferably, the support block has an insertion hole corresponding to the connector, and the connector is rotatably connected to the insertion hole.

[0025] By adopting the above solution, after the connector is inserted into the socket, the sealing ring will seal the gap between the socket and the connector.

[0026] Preferably, the adjusting plate has symmetrically arranged strip grooves inside, and a guide plate passes through the strip grooves. One end of the guide plate is fixedly connected to the bottom of the inner wall of the storage groove. An air extraction head is fixedly connected to the top of the strip grooves. The air extraction head is connected to the insertion hole through a pipe. A vacuum pump is fixedly connected to the bottom of the frame, and the input end of the vacuum pump is connected to the air extraction head through a pipe.

[0027] By adopting the above scheme, the vacuum pump works by extracting air from the inside of the negative pressure groove through the cooperation of the suction head, insertion hole, connector, and round hole, creating negative pressure inside the negative pressure groove, which in turn limits the position of the tray. Conversely, when the vacuum pump stops working, the negative pressure groove no longer creates negative pressure to limit the position of the tray. When adjusting the height of the adjusting plate, it will drive the strip groove to move. Through the cooperation of the strip groove and the guide plate, the adjusting plate will be guided, so that the adjusting plate moves smoothly.

[0028] The beneficial effects of this invention are as follows:

[0029] 1. The ultra-thin pallet transfer machine of the present invention facilitates pallet angle adjustment and transfer through the setting of annular block, rubber ring, and No. 2 power motor. After the position of the concave frame is adjusted and the pallet is lifted, the drive motor is controlled to work. The annular block lifts the pallet, and the No. 2 power motor drives the drive gear to rotate. The drive gear and gear ring cooperate to rotate the annular block. The rotation of the annular block adjusts the pallet angle. After the pallet is adjusted to a predetermined angle, the support block is reset, thus achieving the purpose of adjusting the angle of the ultra-thin pallet. This improves the flexibility of the ultra-thin pallet transfer machine, not only increasing production efficiency but also reducing manual intervention and improving compatibility.

[0030] 2. The ultra-thin pallet transfer machine of the present invention, through the setting of a negative pressure groove, can ensure the stability of the pallet when adjusting the pallet angle and avoid accidental slippage of the pallet. When adjusting the height of the adjusting plate, when the adjusting plate is raised, the vacuum pump works through the cooperation of the air extraction head, the insertion hole, the connector, and the round hole to extract the air inside the negative pressure groove, so as to generate negative pressure inside the negative pressure groove, thereby limiting the position of the pallet and ensuring stability when adjusting the pallet angle.

[0031] 3. The ultra-thin pallet transfer machine of the present invention facilitates pallet position adjustment through the set push plate and electric push rod, and the pallet can be conveyed by the conveyor roller. The control of the electric push rod will push one end of the push plate. When the push plate moves, it will push the position of the pallet on the conveyor roller to move, thereby adjusting the position of the pallet. This facilitates the adjustment and correction of the pallet position, and makes it easier for the next station to process the pallet, thus improving compatibility.

[0032] 4. The ultra-thin pallet transfer machine of the present invention facilitates pallet cleaning through the set diversion groove. A silicone ring is set around the load-bearing plate and fits against the inner wall of the square frame. When the load-bearing plate moves up, it compresses the air above the square frame. The compressed air flows into the inside of the conveying pipe. Through the conveying pipe, the compressed air flows into the diversion groove. Through the air jet hole, the air flows to one side of the pallet surface, thereby cleaning the pallet surface and ensuring the cleanliness of the transported pallets. Attached Figure Description

[0049] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0050] like Figures 1 to 14 As shown in the figure, an ultra-thin pallet transfer machine according to an embodiment of the present invention includes a frame 1, a conveying mechanism for conveying pallets is provided on the frame 1, a limiting mechanism is provided on the frame 1, a square frame 10 is fixedly provided inside the frame 1, a load-bearing plate 12 is provided inside the square frame 10, strip plates 14 are arranged in an array on the load-bearing plate 12, and the top of the strip plates 14 penetrates through the square frame 10. A concave frame 15 is fixedly provided on the top of the strip plates 14. An electric telescopic rod 11 is fixedly provided inside the square frame 10, and the telescopic end of the electric telescopic rod 11 is fixedly connected to the bottom of the load-bearing plate 12. A moving mechanism is provided on the concave frame 15, a support block 18 is provided inside the concave frame 15, an annular groove 19 is provided inside the support block 18, an annular block 20 is rotatably provided inside the annular groove 19, a rubber ring 22 is provided on the top of the annular block 20, an adjusting plate 48 is fixedly connected to the bottom of the support block 18, a gear ring 25 is embedded in the bottom of the annular block 20, and a driving mechanism for driving the annular block 20 to rotate is provided inside the support block 18.

[0051] When using an ultra-thin pallet transfer machine to transfer ultra-thin pallets, after the frame 1 is fixed to the production line with bolts, the ultra-thin pallet moves onto the frame 1 and is then transferred by the conveyor mechanism. The position of the ultra-thin pallet is limited by the limiting mechanism. Then, the operation of the electric telescopic rod 11 will push the load-bearing plate 12 to move. The movement of the load-bearing plate 12 will push the moving mechanism to move through the cooperation of the strip plate 14 and the concave frame 15. The movement of the moving mechanism can change the direction of pallet movement.

[0052] When changing the direction of pallet movement and adjusting the angle of pallet for transfer, after adjusting the position of the concave frame 15 to lift the pallet, the height of the adjusting plate 48 is adjusted by the movement of the telescopic push rod 33, which in turn adjusts the height of the support block 18. When the support block 18 moves, it drives the annular block 20 to move upward. After the top of the annular block 20 contacts the bottom of the pallet, it can limit the position of the pallet. Then, the drive mechanism is controlled to move in cooperation with the gear ring 25 to drive the annular block 20 to rotate. When the annular block 20 rotates, it adjusts the angle of the pallet. After the pallet is adjusted to the predetermined angle, the support block 18 is reset and no longer limits the position of the pallet. Then, the movement mechanism is controlled to move to transfer the pallet, which improves the flexibility of the ultra-thin pallet transfer machine, not only improving production efficiency but also reducing manual intervention and improving compatibility.

[0053] Furthermore, the strip plate 14 is provided with a storage groove 32 inside, and a telescopic push rod 33 is fixedly installed inside the storage groove 32. The telescopic end of the telescopic push rod 33 is fixedly connected to the bottom end of the adjustment plate 48. The square frame 10 is provided with a limiting groove 13 corresponding to the strip plate 14 inside, and the strip plate 14 passes through the limiting groove 13.

[0054] The telescopic push rod 33 is electrically driven (existing technology). When the height of the support block 18 is adjusted, the telescopic push rod 33 is controlled to work, which will adjust the height of the corresponding adjustment plate 48. When the adjustment plate 48 moves, the height of the support block 18 will be adjusted. When the height of the support block 18 is adjusted, the tray can be lifted by the annular block 20.

[0055] When the electric telescopic rod 11 is working, it will push the load-bearing plate 12 to move. When the load-bearing plate 12 moves, it will cause the strip plate 14 to slide inside the limiting groove 13. The limiting groove 13 will limit and guide the strip plate 14, so that the strip plate 14 moves smoothly.

[0056] Furthermore, the drive mechanism includes a support frame 26, a drive gear 27, and a second power motor 28. The support frame 26 is fixedly installed inside the support block 18, and the drive gear 27, which meshes with the gear ring 25, is rotatably installed inside the support frame 26. The second power motor 28, which causes the drive gear 27 to rotate, is fixedly installed inside the support frame 26.

[0057] After the annular block 20 lifts the tray, the second power motor 28 is controlled to work, driving the drive gear 27 to rotate. The drive gear 27 and the gear ring 25 cooperate to make the annular block 20 rotate. When the annular block 20 rotates, it will adjust the angle of the tray.

[0058] Furthermore, the conveying mechanism includes a protective cover 2, a conveying roller 3, a sprocket 4, a reducer 5, and a stepper motor 6. The protective cover 2 is fixedly installed inside the frame 1, the conveying roller 3 is arrayed inside the frame 1, the sprocket 4 is fixedly installed on the conveying roller 3, and adjacent sprockets 4 are connected by chain drive. The reducer 5 and the stepper motor 6 are fixedly installed on the side of the frame 1, and the output end of the stepper motor 6 is connected to the input end of the reducer 5. The output end of the reducer 5 is connected to the corresponding sprocket 4 through drive.

[0059] The protective cover 2 is used to protect the sprocket 4 and prevent external factors from affecting the movement of the sprocket 4. The stepper motor 6 is controlled to work, which will cause the reducer 5 to move. The output end of the reducer 5 is also connected to the sprocket 4. The sprocket 4 is connected to the reducer 5 through a chain. When the reducer 5 moves, it will drive the sprocket 4 to move. The sprocket 4 will drive the conveyor roller 3 to rotate, and the pallet can be conveyed through the conveyor roller 3.

[0060] Furthermore, the limiting mechanism includes a mounting plate 7, an electric push rod 8, and a push plate 9. The mounting plate 7 is fixedly installed inside the frame 1 and is located on one side of the conveyor roller 3. The electric push rod 8 is fixedly installed on the mounting plate 7, and the telescopic end of the electric push rod 8 is fixedly connected to the push plate 9. A conveying pipe 53 is provided on the square frame 10. A diversion groove 51 is embedded inside the push plate 9, and an air jet hole 52 is arrayed on the diversion groove 51.

[0061] The operation of the electric push rod 8 will push the push plate 9 to move. When the push plate 9 moves, it will push the position of the tray on the conveyor roller 3 to move, thereby adjusting the position of the tray.

[0062] A silicone ring is provided around the load-bearing plate 12 and fits against the inner wall of the square frame 10. When the load-bearing plate 12 moves upward, it will compress the air above the square frame 10. The compressed air will flow into the conveying pipe 53. Through the conveying pipe 53, the compressed air will flow into the diversion groove 51. Through the air jet hole 52, the air will flow to one side of the pallet surface, thereby cleaning the pallet surface and ensuring the cleanliness of the conveyed pallet.

[0063] Furthermore, the moving mechanism includes a conveyor belt 16 and a first motor 17. The conveyor belt 16 is disposed inside the concave frame 15, and the first motor 17 corresponding to the conveyor belt 16 is fixedly disposed on the side of the concave frame 15, and the output end of the first motor 17 is connected to the corresponding conveyor belt 16 for transmission.

[0064] When the concave frame 15 moves upward, the pallet is lifted by the conveyor belt 16. Controlling the first motor 17 will cause the conveyor belt 16 to rotate. When the conveyor belt 16 moves, the pallet will move, thereby changing the direction of the pallet's movement to transport materials, which improves flexibility.

[0065] Furthermore, the annular block 20 is provided with a negative pressure groove 21 inside, and a connector 29 is fixedly provided at the bottom center of the annular block 20. The connector 29 is located at the center of the gear ring 25. The annular block 20 is provided with a circular hole 49 inside, and the two ends of the circular hole 49 are respectively connected to the negative pressure groove 21 and the connector 29. A sealing ring 30 is symmetrically provided on the connector 29.

[0066] After the annular block 20 lifts the tray, the rubber ring 22 fits against the bottom of the tray. Through the cooperation of the connector 29 and the round hole 49, the air inside the negative pressure groove 21 is extracted, creating negative pressure inside the negative pressure groove 21, which in turn limits the position of the tray.

[0067] Furthermore, the annular block 20 is surrounded by a circular groove 23, and a limiting ring 24 is rotatably provided inside the circular groove 23, and the outer ring of the limiting ring 24 is fixedly connected to the inner wall of the annular groove 19.

[0068] When the ring block 20 rotates, it will drive the limit ring 24 to rotate. Through the cooperation of the circular groove 23 and the limit ring 24, the ring block 20 will rotate smoothly.

[0069] Furthermore, the support block 18 is provided with a socket 31 corresponding to the connector 29, and the connector 29 is rotatably connected to the socket 31.

[0070] After the connector 29 is inserted into the socket 31, the sealing ring 30 will seal the gap between the socket 31 and the connector 29.

[0071] Furthermore, the adjustment plate 48 is symmetrically provided with strip grooves 36 inside, and a guide plate 37 is provided inside the strip grooves 36. One end of the guide plate 37 is fixedly connected to the bottom of the inner wall of the storage groove 32. A vacuum head 39 is fixedly connected to the top of the strip grooves 36. The vacuum head 39 is connected to the insertion hole 31 through a pipe. A vacuum pump 38 is fixedly connected to the bottom of the frame 1, and the input end of the vacuum pump 38 is connected to the vacuum head 39 through a pipe.

[0072] The vacuum pump 38 works by engaging the suction head 39, the insertion hole 31, the connector 29, and the round hole 49 to extract air from the inside of the negative pressure groove 21, creating a negative pressure inside the negative pressure groove 21, which in turn limits the position of the tray. Conversely, when the vacuum pump 38 stops working, the negative pressure groove 21 no longer generates negative pressure to limit the position of the tray.

[0073] When the height of the adjusting plate 48 is adjusted, the strip groove 36 will move. Through the cooperation of the strip groove 36 and the guide plate 37, the adjusting plate 48 will be guided, so that the adjusting plate 48 moves smoothly.

[0074] Working principle: First, when using the ultra-thin pallet transfer machine to transfer ultra-thin pallets, after the frame 1 is fixed to the assembly line with bolts, the ultra-thin pallet moves onto the frame 1. Then, the stepper motor 6 is activated, causing the reducer 5 to move. The output end of the reducer 5 is also connected to a sprocket 4, which is driven by a chain. Therefore, when the reducer 5 moves, it drives the sprocket 4, which in turn drives the conveyor roller 3 to rotate. The conveyor roller 3 then transfers the pallet. The electric push rod 8 pushes one end of the push plate 9, and as the push plate 9 moves, it moves the position of the pallet on the conveyor roller 3. The position of the pallet can be adjusted. Then, controlling the electric telescopic rod 11 will push the load-bearing plate 12 to move. The movement of the load-bearing plate 12, in conjunction with the strip plate 14 and the concave frame 15, will drive the moving mechanism. After the pallet is lifted by the conveyor belt 16, controlling the first motor 17 will cause the conveyor belt 16 to rotate. The movement of the conveyor belt 16 will move the pallet, thus changing the pallet's direction of movement for material transport, improving flexibility. When changing the pallet's direction of movement, adjusting the pallet's angle for transfer, after adjusting the position of the concave frame 15 and lifting the pallet, the telescopic push rod 33 will rotate... The height of the adjustment plate 48 is adjusted. When the adjustment plate 48 moves, the height of the support block 18 is also adjusted. When the height of the support block 18 is adjusted, the tray can be lifted by the annular block 20. When the height of the adjustment plate 48 is adjusted, the upward movement of the adjustment plate 48 will drive the strip groove 36 to move synchronously. When the strip groove 36 moves, the vacuum pump 38 works by cooperating with the suction head 39, the insertion hole 31, the connector 29, and the round hole 49 to extract the air inside the negative pressure groove 21, creating a negative pressure inside the negative pressure groove 21, which can limit the position of the tray. Conversely, when the vacuum pump 38 stops working, the tray can be moved upward. The negative pressure groove 21 no longer generates negative pressure to limit the position of the pallet. After the annular block 20 lifts the pallet to its limit position, the second power motor 28 is controlled to work, driving the drive gear 27 to rotate. The drive gear 27 and the gear ring 25 cooperate to make the annular block 20 rotate. When the annular block 20 rotates, it will adjust the angle of the pallet. After the pallet is adjusted to the predetermined angle, the support block 18 is reset and no longer limits the pallet. Then, the moving mechanism is controlled to move, and the pallet can be transferred. This improves the flexibility of the ultra-thin pallet transfer machine, not only improving production efficiency but also reducing manual intervention and improving compatibility.

[0075] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
