Description

Technical Field

[0001] This invention relates to the technical field of expansion joint production, specifically to an intelligent transfer device for expansion joint production. Background Technology

[0002] As is generally known, an expansion joint is a flexible component used in piping systems. It is mainly used to absorb displacement caused by temperature changes, mechanical deformation, or other factors in the pipeline, while also reducing stress in the pipeline system and ensuring the safe operation of the pipeline system.

[0003] In the production of expansion joints, transfer is an indispensable link. The production of expansion joints usually involves multiple processes, such as cutting, welding, forming, heat treatment, and testing of raw materials. In order to ensure the continuity of the production process, raw materials, semi-finished products and finished products need to be transferred between various processes.

[0004] For example, the patent with announcement number CN119059414A, announcement date December 3, 2024, and titled "A Low-Temperature Expansion Joint Production Line," includes a conveying device one and a conveying device two. Two support frames are installed at the outer ends of the conveying devices one and two. A moving device is fixedly installed on the upper inner side of the support frames. The moving device includes a slide rail, a slider is slidably installed inside the slide rail, and a clamping block is installed at the bottom of the slider. Electric telescopic rods are fixedly installed at both ends of the clamping block. A clamping plate is fixedly installed at the inner end of the electric telescopic rod, and an insertion rod is fixedly installed on the lower inner side of the clamping plate. This invention installs a moving device between the conveying devices one and two. The slider in the moving device moves, causing the clamping plate at the bottom to move, thereby moving the insertion rod and clamping the low-temperature expansion joint. The working of the moving device and the extension and retraction of the electric telescopic rod two enable the transfer of the low-temperature expansion joint, avoiding collisions.

[0005] Since expansion joints are mostly thin-walled stainless steel structures and have critical functional parts such as flange sealing surfaces and corrugated sections, when transferring expansion joints to flaw detection equipment for inspection, the ultrasonic probe of the flaw detection equipment needs to emit high-frequency sound waves into the expansion joint. After the sound waves are reflected by the defects, they are transmitted back to the probe to form a defect signal. In this process, the axis of the expansion joint needs to be aligned with the flaw detection equipment to avoid the incident angle between the ultrasonic probe and the expansion joint deviating from the preset value, which would increase the detection error. However, the shortcoming of the existing technology is that the suspended conveyor mechanism is prone to shaking during operation, making it difficult to calibrate the position in time before the expansion joint arrives at the flaw detection equipment. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent transfer device for expansion joint production, solving the technical problems in related technologies. To achieve the above objective, this invention provides the following technical solution: An intelligent transfer device for producing expansion joints includes a suspended conveying mechanism, a clamping mechanism suspended from the suspended conveying mechanism, an upper base arranged on the suspended conveying mechanism, and a lower base arranged on the clamping mechanism. The upper base and the lower base are oscillatingly arranged, and an adjustment mechanism is provided between the upper base and the lower base. A position detection mechanism is arranged on the clamping mechanism. The adjustment mechanism adjusts the position of the expansion joint in real time based on the detection signal from the position detection mechanism.

[0007] The aforementioned adjustment mechanism includes a plurality of first electromagnets arranged circumferentially on the upper base and a plurality of second electromagnets arranged circumferentially on the lower base. The plurality of first electromagnets and the plurality of second electromagnets correspond one-to-one, and the position of the expansion joint is adjusted based on the change in magnetic force between the first electromagnets and the second electromagnets.

[0008] The aforementioned clamping mechanism includes a support connected to the lower base, and two clamping arms are arranged on the support. Each clamping arm has a fixed jaw and a movable jaw at the end away from the support, and each clamping arm is provided with a driving component. Based on the driving action of the driving component, the movable jaw approaches the fixed jaw to clamp the flange portion of the expansion joint. Both the fixed jaw and the movable jaw have an arc-shaped structure, and a rubber pad is arranged on the surface of the expansion joint.

[0009] As mentioned above, the clamping arm has an arc-shaped structure, and when the expansion joint is clamped, its center of gravity is offset from the position directly below the support.

[0010] As mentioned above, the support is provided with a distance adjustment mechanism for adjusting the distance between the two clamping arms.

[0011] As described above, the fixed gripper is mounted on the clamping arm via a connecting block, and a support rod is slidably provided on the connecting block. The movable gripper is fixed to one end of the support rod, and the power output end of the driving component is connected to the movable gripper.

[0012] As mentioned above, both the fixed clamp and the movable clamp are provided with side clamps on the side of the flange sealing surface near the expansion joint, and guide slopes are provided on the side clamps.

[0013] As described above, a support mechanism for supporting the corrugated section of the expansion joint is arranged between the two fixed grippers.

[0014] As described above, the connecting block is oscillatingly arranged on the corresponding clamping arm, and the clamping arm is provided with a limiting mechanism to restrict the oscillation of the connecting block. The support mechanism is positioned at the middle of the fixed jaw. The expansion joint is fully clamped and supported with two strokes: In the first stroke, the driving member drives the movable jaw to approach the corresponding fixed jaw to clamp the flange part of the expansion joint, and during this process, the limiting mechanism restricts the oscillation of the connecting block; In the second stroke, the limiting mechanism removes the oscillation restriction on the connecting block, and the driving member drives the fixed jaw and the corresponding movable jaw to oscillate together. The fixed jaw forms a support for the flange part of the expansion joint, and the support mechanism forms a support for the corrugated section of the expansion joint.

[0015] The aforementioned support mechanism includes a push block slidably arranged on a fixed gripper, an adjustment block rotatably provided on the push block, an adjustment screw screwed onto the adjustment block, a support plate body installed between the two adjustment screws, and the adjustment screws and the support plate body are hinged together.

[0016] The beneficial effects of this invention are as follows: by setting a position detection mechanism, the position change of the expansion joint can be detected in real time. Then, the adjustment mechanism can adjust the position of the expansion joint in real time according to the signal of the position detection mechanism, so that its axial direction can remain basically unchanged, so as to smoothly align with the flaw detection equipment, improve flaw detection efficiency, and reduce flaw detection error.

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 To be continued Figure 6 The present invention will now be described in further detail.

[0021] In this embodiment of the invention, an intelligent transfer device for the production of expansion joints 3 is provided, including a suspended conveying mechanism 1, a clamping mechanism 2 suspended from the suspended conveying mechanism 1, the clamping mechanism 2 clamping the expansion joints 3, an upper base 10 arranged on the suspended conveying mechanism 1, a lower base 11 arranged on the clamping mechanism 2, the upper base 10 and the lower base 11 being oscillatingly arranged, and an adjustment mechanism being provided between the upper base 10 and the lower base 11; a position detection mechanism is arranged on the clamping mechanism 2; the adjustment mechanism adjusts the position of the expansion joints 3 in real time based on the detection signal of the position detection mechanism.

[0022] Specifically, the suspended conveying mechanism 1 achieves the transfer and conveying of the expansion joint 3 by erecting a track system in the air and then arranging several clamping mechanisms 2 on the track system for clamping the expansion joint 3. The suspended conveying mechanism 1 is existing technology and will not be described in detail here. The content of the suspended conveying mechanism 1 in the figure is not fully shown. The expansion joint 3 being transported generally consists of a corrugated section 31 and flanges 30 arranged at both ends of the axial direction of the corrugated section 31. After it is manufactured, it needs to undergo a flaw detection process to eliminate defective parts. However, when using flaw detection equipment to perform flaw detection on the expansion joint 3, the axial direction of the expansion joint 3 needs to be aligned with the flaw detection equipment to avoid the incident angle between the ultrasonic probe and the expansion joint 3 deviating from the preset value, which would increase the detection error. However, when the existing suspension conveying mechanism 1 transports the expansion joint 3, it is difficult to ensure that the expansion joint 3 remains in a certain position before reaching the flaw detection equipment. For example, wear of the connection structure between the suspension conveying mechanism 1 and the clamping mechanism 2, or wear of the suspension conveying mechanism 1 itself, can cause running sway problems, making it difficult for the expansion joint 3 to move axially toward the flaw detection equipment during the transport process.

[0023] Based on the aforementioned technical problems, in this embodiment, a mechanism for calibrating the position of the expansion joint 3 is arranged between the suspension conveying mechanism 1 and the clamping mechanism 2. This means that the connection structure between the suspension conveying mechanism 1 and the clamping mechanism 2 is improved. Specifically, an upper base 10 is provided on the suspension conveying mechanism 1, and a lower base 11 is arranged on the clamping mechanism 2. The upper base 10 and the lower base 11 have essentially the same shape and are symmetrically arranged. Then, a spherical hinge is arranged between the upper base 10 and the lower base 11 to enable the lower base 11 to drive the clamping mechanism 2 to swing. The lower base 11 can drive the clamping mechanism 2 to swing. After mechanism 2 swings, its swing angle needs to be limited. That is, an adjustment mechanism is arranged between the upper base 10 and the lower base 11 to adjust the position of the lower base 11 relative to the upper base 10. A position detection mechanism (such as a displacement sensor, angle sensor, etc., which is existing technology and will not be described in detail) is also arranged on the clamping mechanism 2 to detect the position change of the clamping mechanism 2 in real time, thereby obtaining the position change of the expansion joint 3. Then, the adjustment mechanism adjusts the position of the lower base 11 according to the detection signal of the position detection mechanism. The adjustment mechanism can be adjusted by some cylinders or hydraulic cylinders.

[0024] The beneficial effect of this embodiment is that by setting a position detection mechanism, the position change of the expansion joint 3 can be detected in real time. Then, the adjustment mechanism can adjust the position of the expansion joint 3 in real time according to the signal of the position detection mechanism, so that its axial direction can remain basically unchanged, so as to smoothly align with the flaw detection equipment, improve flaw detection efficiency, and reduce flaw detection error.

[0025] Preferably, the adjustment mechanism includes a plurality of first electromagnets 12 arranged circumferentially on the upper base 10 and a plurality of second electromagnets 13 arranged circumferentially on the lower base 11, wherein the plurality of first electromagnets 12 and the plurality of second electromagnets 13 correspond one-to-one, and the position of the expansion joint 3 is adjusted based on the magnetic force change between the first electromagnets 12 and the second electromagnets 13.

[0026] Specifically, in this embodiment, the interaction between the first electromagnet 12 and the second electromagnet 13 after the change in magnetic force is used to adjust the position of the lower base 11 relative to the upper base 10, thereby realizing real-time adjustment of the position of the expansion joint 3.

[0027] Preferably, the clamping mechanism 2 includes a support 20 connected to the lower base 11. Two clamping arms 21 are arranged on the support 20. Each clamping arm 21 is provided with a fixed jaw 22 and a movable jaw 23 at the end away from the support 20. Each clamping arm 21 is provided with a driving member 24. Based on the driving action of the driving member 24, the movable jaw 23 approaches the fixed jaw 22 to clamp the flange 30 part of the expansion joint 3. Both the fixed jaw 22 and the movable jaw 23 have an arc-shaped structure, and a rubber pad 25 is arranged on the surface of the expansion joint 3.

[0028] Specifically, the support 20 has a cuboid structure and two clamping arms 21 are arranged on it. Depending on the length of the expansion joint 3, the distance between the two clamping arms 21 needs to be adjusted. Therefore, the support 20 is also equipped with a distance adjustment mechanism to adjust the distance between the two clamping arms 21. This mechanism includes a slide rail along the length of the support 20, with two sliders sliding within the slide rail. Each slider is connected to a corresponding clamping arm 21. The distance between the two sliders can be adjusted by a length adjustment mechanism (such as a screw drive mechanism or a linear cylinder). The fixed clamping jaw 22 remains stationary on its corresponding clamping arm 21, while the movable clamping jaw 23, driven by the driving component 24, can move closer to or further away from the corresponding fixed clamping jaw 22. This allows for clamping or releasing the flange 30 portion of the expansion joint 3. In other words, the fixed clamping jaw 22 is mounted on the clamping arm 21 via a connecting block 27 (here, the connecting block 27 can...). The movable gripper 23 is fixed to one end of the support rod 28 by bolts. The sliding direction of the support rod 28 is parallel to the moving direction of the movable gripper 23 when it approaches or moves away from the fixed gripper 22. The power output end of the drive member 24 is connected to the movable gripper 23. Thus, the drive member 24 can be a linear cylinder. Its extension and retraction change drives the movable gripper 23 to approach or move away from the fixed gripper 22. The support rod 28 plays a guiding and supporting role in the movement of the movable gripper 23. When the movable gripper 23 approaches or moves away from the fixed gripper 22, it moves in a straight line. Compared with using the swing of the gripper to clamp the target object, the clamping method in this embodiment can directly achieve surface contact between the gripper and the target object, rather than point contact. This can reduce or eliminate the concentrated clamping stress on the target object and prevent the flange 30 from deforming due to the concentrated clamping stress.

[0029] Both the fixed clamp 22 and the movable clamp 23 have an arc-shaped structure, and the surface of the flange 30 part that is in contact with the expansion joint 3 is provided with a rubber pad 25. That is, the flange 30 of the expansion joint 3 is basically circular. When the fixed clamp 22 and the movable clamp 23 with arc-shaped structure cooperate to clamp, they can form a circular wrap around the flange 30 part. The rubber pad 25 can undergo elastic deformation after being squeezed, thereby adapting to the arc-shaped structure of the flange 30 part. In this way, the clamping of the flange 30 part is more close.

[0030] In an optional embodiment, the clamping arm 21 has an arc-shaped structure, and when the expansion joint 3 is clamped, its center of gravity is offset from the position directly below the support 20. Specifically, one end of the clamping arm 21 is connected to a slider, and the other end is connected to a connecting block 27, which has an arc-shaped structure. This can drive the position of the fixed claw 22 away from the position directly below the support 20. Thus, after clamping the expansion joint 3, the overall center of gravity of the clamping mechanism 2 is offset from the position directly below the support 20. Under the influence of gravity, it tends to swing downwards towards the support 20. Therefore, the first electromagnet 12 and the second electromagnet 13 need to always have an interacting magnetic force. In this way, the change in magnetic force can be used to determine whether the position of the expansion joint 3 has changed.

[0031] Preferably, both the fixed clamp 22 and the movable clamp 23 are provided with side clamps 26 on the side of the flange 30 sealing surface of the expansion joint 3, and the side clamps 26 are provided with guide slopes 260.

[0032] Specifically, before clamping the expansion joint 3, the distance between the two clamping arms 21 needs to be adjusted according to the overall axial length of the expansion joint 3 in its non-working state, so that each fixed jaw 22 and the corresponding movable jaw 23 can just clamp the flange 30 part of the expansion joint 3. Before the expansion joint 3 is clamped, its position will inevitably be slightly different from the corresponding positions of the fixed jaw 22 and the movable jaw 23. Therefore, side clamping plates 26 are arranged on both the fixed jaw 22 and the movable jaw 23. The side clamping plates 26 are also equipped with guide slopes 260. That is, when clamping the expansion joint 3, the guide slopes 260 first contact the flange 30 part, and the wedge-shaped clamping action can squeeze the expansion joint 3 towards the middle position of the two clamping arms 21. In this way, the clamping position of the flange 30 part is more accurate, and when the expansion joint 3 is clamped, the two side clamping plates 26 can also play a restrictive role at both ends of the axial direction of the expansion joint 3.

[0033] Furthermore, a support mechanism 4 for supporting the corrugated section 31 of the expansion joint 3 is arranged between the two fixed grippers 22.

[0034] Specifically, the corrugated section 31 in the middle of the expansion joint 3 is mostly a thin-walled stainless steel structure. Under the action of gravity, it may sag. During the transportation process, it is necessary to support the corrugated section 31 to reduce its sag and avoid plastic deformation, which would affect its performance. Therefore, in this embodiment, a support mechanism 4 is arranged between the two fixed jaws 22 to support the corrugated section 31 so that it does not sag when the expansion joint 3 is transported.

[0035] Furthermore, the connecting block 27 is oscillatingly arranged on the corresponding clamping arm 21, and the clamping arm 21 is provided with a limiting mechanism 5 to restrict the oscillation of the connecting block 27. The support mechanism 4 is positioned aligned with the middle position of the fixed jaw 22. The expansion joint 3 is fully clamped and supported with two strokes: In the first stroke, the driving member 24 drives the movable jaw 23 to approach the corresponding fixed jaw 22 to clamp the flange 30 part of the expansion joint 3, and during this process, the limiting mechanism 5 restricts the oscillation of the connecting block 27; In the second stroke, the limiting mechanism 5 removes the oscillation restriction on the connecting block 27, and the driving member 24 drives the fixed jaw 22 and the corresponding movable jaw 23 to oscillate together. The fixed jaw 22 forms a support for the flange 30 part of the expansion joint 3, and the support mechanism 4 forms a support for the corrugated section 31 of the expansion joint 3.

[0036] Specifically, in the aforementioned embodiment, when the support mechanism 4 supports the corrugated section 31, the support mechanism 4 needs to extend under the corrugated section 31 when clamping the expansion joint 3. By pressing from the side or lifting upwards, the drooping part of the corrugated section 31 is supported and restored. Although this achieves support for the corrugated section 31, it also brings problems. That is, the drooping part of the corrugated section 31 is supported and restored passively, rather than by its own position change. As a result, the support mechanism 4 may cause plastic deformation of the corrugated section 31, affecting the use effect of the corrugated section 31.

[0037] Therefore, in this embodiment, the connecting block 27 is oscillating on the corresponding clamping arm 21, and its oscillation angle is limited by the limiting mechanism 5. The position of the support mechanism 4 needs to be changed, placing it in the middle of the fixed clamp 22. That is, when clamping the expansion joint 3, the support mechanism 4 is positioned on the side of the corrugated section 31. This allows the clamping of the expansion joint 3 to be divided into two strokes. In the first stroke, the driving member 24 drives the movable clamp 23 closer to the fixed clamp 22, gradually clamping the flange 30 portion of the expansion joint 3. At this time, the limiting mechanism 5 needs to limit the oscillation of the connecting block 27 until the fixed clamp 22, in conjunction with the corresponding movable clamp 23, completely clamps the flange 30 portion. Then, the second stroke begins. When the driving member 24 can no longer drive the movable clamp 23 closer to the corresponding fixed clamp 22, the limiting mechanism 5 removes the oscillation restriction on the connecting block 27. When the driving member 24 continues to drive the movable clamp 23 closer to the fixed clamp 22, the expansion joint 3, connecting block 27, and fixed clamp are clamped together. When the fixed gripper 22 and the movable gripper 23 are flipped together, the position of the support mechanism 4 relative to the corrugated section 31 will also change. That is, the support mechanism 4 will change from the side of the corrugated section 31 to the bottom of the corrugated section 31. During this process, the corrugated section 31 is subjected to gravity, and its drooping part is equivalent to gradually rolling and changing to contact the support mechanism 4 (equivalent to flipping 90 degrees) and being passively squeezed or lifted. The probability of plastic deformation of the corrugated section 31 will be greatly reduced. After flipping 90 degrees, the limiting mechanism 5 will again limit the swing of the connecting block 27 to ensure the stability during the transfer process. After flipping 90 degrees, the fixed gripper 22 will support the flange 30 part of the expansion joint 3. The limiting mechanism 5 will limit the swing of the connecting block 27. Then the drive component 24 can drive the movable gripper 23 away from the fixed gripper 22 by a certain distance (such as half the deformation of the rubber pad 25 set on the movable gripper 23). This can reduce the clamping force acting on the flange 30 part.

[0038] In one of the optional embodiments, the support mechanism 4 includes a push block 40 slidably arranged on a fixed gripper 22, an adjustment block 41 rotatably provided on the push block 40, an adjustment screw 42 screwed onto the adjustment block 41, a support plate 43 installed between the two adjustment screws 42, and the adjustment screws 42 and the support plate 43 are hinged together.

[0039] Specifically, when adjusting the distance between the two clamping arms 21, the support plate 43 should be positioned closer to the middle of the corrugated section 31 (because the sag of the corrugated section 31 is mainly concentrated in the middle). Therefore, when the distance between the two clamping arms 21 changes, the adjusting screw 42 needs to be adjusted first to change the position of the support plate 43. When clamping the flange 30, the position of the support plate 43 should also change so that it can abut against the outer surface of the corrugated section 31 during subsequent use. Therefore, a push block 40 is radially slidably arranged in the middle of the fixed jaw 22. The push block 40 is connected to the rubber pad 25, and an adjusting block 41 is rotatably arranged on the push block 40. Adjusting screw 42 is screwed onto 41, and adjusting screw 42 is hinged to support plate 43. As a result, the distance between the two clamping arms 21 changes, the distance between support plate 43 and corrugated section 31 also changes. Therefore, when adjusting the position of support plate 43, it is necessary to make corresponding adjustments according to the distance between the two clamping arms 21. When rubber pad 25 is partially squeezed by flange 30 and undergoes elastic deformation, it will drive push block 40 to move. The movement of push block 40 will drive support plate 43 to move away from corrugated section 31. In this way, when expansion joint 3 is fully clamped again, support plate 43 can just support corrugated section 31 to prevent it from sagging due to gravity.

[0040] The limiting mechanism 5 includes a limiting groove 50 formed on the clamping arm 21, a limiting rod 51 slidably disposed within the limiting groove 50, a limiting block 52 slidably disposed on the connecting block 27, and the limiting rod 51 slidably disposed on the limiting block 52, with a spring connecting the two. Based on the elastic force of the spring, the limiting rod 51 always tends to insert into the limiting groove 50. The limiting groove 50 includes a first limiting point 500, a second limiting point 502, a first segment 501 connecting the first limiting point 500 and the second limiting point 502, and a second segment 503 connecting the second limiting point 502 and the first limiting point 500. The axial depth of the first segment 501 along the limiting rod 51 is less than the depth of the first limiting point 500 and also less than the depth of the second limiting point 502. The depth of the end of segment 503 near the second limiting point 502 is greater than the depth of the second limiting point 502, and the depth of the end of segment 503 near the first limiting point 500 is less than the depth of the first limiting point 500. The first limiting point 500, the first segment 501, the second limiting point 502, and the second segment 503 form a closed channel. That is, during the swing stroke of the connecting block 27 (that is, the support mechanism 4 changes from the side of the corrugated segment 31 to the bottom of the corrugated segment 31), the limiting rod 51 will first be pulled away from the first limiting point 500, then enter the first segment 501, and slide from the first segment 501 into the second limiting point 502. At this time, the connecting block 27 rotates 90 degrees in the forward direction. When the connecting block 27 needs to rotate 90 degrees in the reverse direction, the driving component 24 drives the movable clamp. Claw 23 continues to move forward and backward at a certain angle, such as 5 degrees. Then, the limiting rod 51 will enter the second segment 503 from the second limiting point 502. Subsequently, during the process of the connecting block 27 being driven to rotate 90 degrees in the opposite direction, the limiting rod 51 slides into the first limiting point 500 from the second segment 503. During this process, the limiting block 52 can slide on the connecting block 27, allowing the limiting rod 51 to move smoothly within the limiting groove 50. A first pressing block 53 is arranged on the support rod 28. The position of the first pressing block 53 on the support rod 28 can be adjusted according to the diameter of the flange 30. A second pressing block 54 is slidably arranged within the connecting block 27. An elastic element is provided between the second pressing block 54 and the connecting block 27. The first pressing block 53 and the second pressing block 54... The wedge-shaped fit between blocks 54 achieves the extrusion action. A pressure-receiving surface 510 is provided on the limiting rod 51. When the second extrusion block 54 extrudes the pressure-receiving surface 510 (the two blocks also achieve the extrusion action through a wedge-shaped fit), it drives the limiting rod 51 to insert into the first limiting point 500, preventing the limiting rod 51 from entering the first segment 501. At this time, the position of the connecting block 27 is restricted. When the first extrusion block 53 extrudes the second extrusion block 54, causing the second extrusion block 54 to release its pressure on the pressure-receiving surface 510, the limiting rod 51, under the action of the spring, will pull away from the first limiting segment by a certain distance. The swing restriction of the connecting block 27 disappears, and the limiting rod 51 can be driven into the first segment 501 by the swing of the connecting block 27. Conversely, when the first extrusion block 53 does not extrude the second extrusion block 54...Under the elastic force of the spring, the limiting rod 51 tends to extend out of the limiting block 52. When it aligns with the first limiting point 500, the limiting rod 51 will insert into the deepest part of the first limiting point 500, preventing the limiting rod 51 from moving into the first segment 501. This ensures that the position of the connecting block 27 does not change when clamping the expansion joint 3, allowing for smooth clamping of the expansion joint 3. Furthermore, after a 90-degree forward rotation, it prevents the position of the expansion joint 3 from changing during transport. Even if the driving component 24 fails, it will not affect the position of the expansion joint 3.

[0041] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
