Description

Technical Field

[0001] The invention relates to the technical field of steel wire rope production equipment, in particular to a stainless steel wire rope end ring forming mechanism. Background Art

[0002] Wire rope is a spiral bundle of steel wires twisted together according to certain rules with steel wires that meet the requirements of mechanical properties and geometric dimensions. It is composed of steel wires, rope core and grease. The wire rope is first twisted into strands by multiple layers of steel wires, and then a certain number of strands are twisted into a spiral rope with the rope core as the center. It is used for lifting, traction, tensioning and carrying in material handling machinery. In addition, after the preparation of the wire rope, it is usually necessary to use a U-shaped bayonet to connect it to the end, or fold the wire rope in half and pass it through an aluminum alloy sleeve, and then compact the aluminum alloy sleeve.

[0003] When a thicker steel wire rope is looped, an aluminum alloy sleeve is generally used for compaction to fix the end of the steel wire rope. Before compaction, the steel wire is folded in half and passed through the aluminum alloy sleeve. During the compaction process, the two strands of steel wire rope will squeeze each other, which can easily deform the end of the steel wire rope. Since the geometric shape of each steel wire in the steel wire rope is equivalent to a spiral line around a cylinder, a repulsive force will be generated when the steel wire is twisted. The repulsive force in the steel wire rope strands makes the steel wire rope tend to loosen. Therefore, when the steel wire rope is processed, a pre-deformation is used to generate a stress, namely friction, inside the steel wire rope to eliminate the repulsive force generated during the twisting process. However, after the steel wire rope is squeezed and deformed, the structure of the steel wire rope changes, resulting in the imbalance of its internal stress and repulsive force, and the phenomenon of loose strands is likely to occur, thereby reducing the strength of the steel wire rope. In the prior art, the bent end of the steel wire rope is generally fixed firmly with a rope or steel wire. However, during the compaction process, the end of the steel wire rope will slide and deform between the rope or steel wire, and the phenomenon of loose strands cannot be solved well.

[0004] Therefore, a stainless steel wire rope end ring forming mechanism is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a stainless steel wire rope end ring-forming mechanism, which first fixes the wire rope through a fixing mechanism and has the same shape as the outer wall of the wire rope, so that the wire rope can maintain its own structural stability during the compaction process, thereby avoiding the phenomenon of loose strands caused by mutual squeezing of the wire ropes.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A stainless steel wire rope end ring-forming mechanism comprises a base, a support frame, a mold assembly, a fixing assembly, and a lower hydraulic press, wherein the support frame is mounted on the top of the base, a connecting hole is provided on the top of the base, a first inner cavity is provided inside the base, the first inner cavity is communicated with the connecting hole, the lower hydraulic press is mounted inside the first inner cavity, the mold assembly is mounted on the top of the lower hydraulic press, and the fixing assembly is mounted on the mold assembly, a fixing sleeve is first placed on the mold assembly, and then the end of the steel wire rope is passed through the fixing assembly and the fixing sleeve to form a circle, so that two strands of steel wire rope are placed side by side in the fixing sleeve, and then the mold assembly is driven upward by the lower hydraulic press to extrude the fixing sleeve, and during the extrusion process, the two strands of steel wire rope are fixed by the fixing assembly to reduce the deformation of the steel wire rope during extrusion, thereby reducing the internal stress change of the steel wire rope.

[0008] Preferably, the mold assembly includes a fixed seat, a lower mold, a fixed plate, an upper mold, and a fixed column. The fixed seat is installed on the top of the lower hydraulic press, the lower mold and the fixed assembly are both installed on the top of the fixed seat, and the fixed assembly is located at the top of the lower mold. The fixed seat is provided with a first slide groove on both sides, and a first slider is slidably connected inside the first slide groove. The fixed plate is connected to the first slider, the fixed column is installed on the top of the inner wall of the support frame, and the upper mold is installed at the bottom of the fixed column. A lower rectangular groove is provided on the top of the lower mold and the top of the upper mold, and the width of the rectangular groove is the same as that of the fixed sleeve.

[0009] In the above scheme, the fixing sleeve is placed horizontally inside the rectangular slot, and then the lower hydraulic press is started to drive the fixing seat to move upward to squeeze the fixing sleeve. Because the width of the rectangular slot is the same as that of the fixing sleeve, the rectangular slot limits the fixing sleeve, thereby avoiding the fixing sleeve from moving forward and backward during the extrusion process, thereby affecting the firmness of the fixation.

[0010] Furthermore, a top block is connected to the bottom of the inner wall of the rectangular slot, the cross section of the top block is set to be a pentagon, and the two oblique sides of the top block are set to be arcs.

[0011] In the above scheme, when the two steel wires are fitted together, there is a gap between the fitting point between the two steel wire ropes and the inner wall of the fixed sleeve, and the gap is eliminated by the top block. The two oblique sides of the top block are set to be arc-shaped to squeeze the bottom and top of the inner wall of the fixed sleeve into an arc shape, so that the inner wall of the fixed sleeve can better fit the outer wall of the steel wire rope.

[0012] Furthermore, a fixed block is connected to the top of the fixed plate, a side hydraulic press is fixedly connected to the top of the fixed block, a pressing block is connected to the extended end of the side hydraulic press, and an arc-shaped groove is provided on the side of the pressing block close to the lower mold.

[0013] In the above scheme, when the upper mold and the lower mold squeeze the fixed sleeve, the side hydraulic presses on the left and right sides drive the pressing blocks to move and compact the sides of the fixed sleeve, so that the fixed sleeve and the wire rope are compacted and the wire ropes are fitted together.

[0014] Furthermore, the width of the pressing block is equal to the width of the rectangular slot, and the vertical length of the first straight side of the arc-shaped slot is equal to the second straight side of the top block.

[0015] In the above scheme, the width of the pressing block is equal to the width of the two rectangular slots, so that the pressing block fits inside the rectangular slots, thereby reducing the gap generated during the extrusion process. The vertical length of the first straight side of the rectangular slot is equal to the second straight side of the top block, so that the annular inner wall formed by the arc-shaped slot on one side of the pressing block and the top of the outer wall of the top block is smooth, thereby reducing the gap between the wire rope and the fixed sleeve during extrusion.

[0016] Preferably, the fixing assembly includes a moving block, a splint, and a baffle. A second slide groove is provided on the top of the lower mold, a second slide groove is connected to the inside of the second slide groove, the top of the second slide block is connected to the bottom of the moving block, a first groove is provided on the top of the moving block, a splint is connected to the inside of the first groove, a threaded hole is provided on the right side of the moving block, a threaded rod is connected to the inside of the threaded hole, the right end of the threaded rod is connected to the splint, the left end of the threaded rod is connected to a crank, and the baffle is installed on the top of the lower mold.

[0017] In the above scheme, after the steel wire passes through the fixing sleeve and is bent, it passes between the fixing plate and the left inner wall of the first groove, and then the handle is shaken to move the fixing plate toward the left inner wall of the first groove, thereby fixing the steel wire rope.

[0018] Furthermore, arc grooves are provided on opposite surfaces of the moving block and the clamping plate, and the inner wall of the arc groove is twisted and has the same shape as the outer wall of the wire rope.

[0019] In the above scheme, the arc-shaped groove is used to fit the outer wall texture of the steel wire rope, so as to maintain the stability of the structure of the steel wire rope itself, thereby reducing the occurrence of loose strands.

[0020] Preferably, a sliding hole is provided at the bottom of the fixed column, a first spring is connected to the top of the sliding hole, a sliding block is connected to the bottom of the first spring, a second groove is provided at the bottom of the sliding block and the top of the blocking block, the vertical center lines of the two second grooves are in the same straight line, and the inner wall of the second groove has the same shape as the outer wall of the wire rope.

[0021] In the above scheme, the steel wire rope first passes through the second groove and then passes through the fixed sleeve. When the upper mold moves upward, the bottom of the sliding block fits with the top of the fixed block, so that the two second grooves wrap the steel wire rope and fix it.

[0022] Preferably, a second through hole is provided on the front side of the baffle, a spiral groove is provided on the inner wall of the second through hole, and a third slider is connected to the inner wall of the spiral groove. A movable disk is connected to the inside of the second through hole, and the outer wall of the movable disk is connected to the third slider. A connecting groove is provided on the rear side of the movable disk, and a chuck is connected to the inside of the connecting groove through a bearing. A flower groove is provided on the rear side of the chuck, and the flower groove fits with the end of the wire rope.

[0023] In the above scheme, after the steel wire rope is bent and passes through the fixing sleeve, one end of the bent steel wire rope is fitted into the rectangular slot to fix the end of the steel wire rope to avoid loose strands during the extrusion process. When the steel wire rope pushes the clamping plate to move, the moving disk drives the clamping disk to rotate, so that the clamping disk generates torque on the steel wire rope, increases the stress inside the steel wire rope, and further reduces the occurrence of loose strands.

[0024] Furthermore, the inner wall of the connecting groove is provided with ratchet teeth, and the outer wall of the chuck is connected to a plurality of elastic paddles, and the elastic paddles cooperate with the ratchet teeth.

[0025] In the above scheme, the movable plate drives the chuck to rotate through the cooperation of the ratchet teeth and the paddle. When the torque between the chuck and the wire rope is large, the elastic paddle bends, causing the chuck to rotate unidirectionally in the movable plate, thereby preventing the wire rope from being damaged by excessive torque.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The fixing sleeve is extruded by the upper and lower dies, and the outside of the wire rope is fixed by the fixing assembly. When the wire rope is extruded, its own structure is kept stable, and its internal stress remains unchanged, so as to avoid the reduction of the strength of the wire rope due to the phenomenon of loose strands of the wire rope during extrusion.

[0028] 2. By setting a top block, during the extrusion process, when the two steel wires are fitted together, the deformation of the steel wire rope is reduced, so that there is a certain gap between the fitting part of the two steel wire ropes and the inner wall of the fixed sleeve. The top block is used to extrude the middle part of the outer wall of the fixed sleeve to make the middle part of the fixed sleeve shrink inward, thereby eliminating the gap between the fitting part of the two steel wire ropes and the inner wall of the fixed sleeve, making the fixed sleeve and the steel wire rope more tightly combined.

[0029] 3. By setting a baffle, when the wire rope is bent and passes through the fixed sleeve, the bent end of the wire rope is fitted into the rectangular slot to fix the wire rope end to avoid loose strands during the extrusion process. When the wire rope pushes the card plate to move, the movable plate drives the card plate to rotate inside the baffle to generate torque on the wire rope, further preventing the stress inside the wire rope from being reduced. When the torque of the wire rope is large, the card plate rotates inside the movable plate to avoid damage to the wire rope due to excessive torque. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] A stainless steel wire rope end looping mechanism, referring to Figure 1 and Figure 2 , including a base 1, a support frame 2, a mold assembly 3, a fixing assembly 4, and a lower hydraulic press 5. The support frame 2 is installed on the top of the base 1. A connecting hole 11 is opened on the top of the base 1. The connecting hole 11 is located in the middle of the base 1. A first inner cavity 12 is opened inside the base 1. The first inner cavity 12 is connected with the connecting hole 11. The lower hydraulic press 5 is installed in the first inner cavity 12, the mold assembly 3 is installed on the top of the lower hydraulic press 5, and the fixing assembly 4 is installed on the mold assembly 3. First, the fixing sleeve 13 is placed on the mold assembly 3, and then the end of the wire rope passes through the fixing assembly 4 and the fixing sleeve 13 to form a circle, so that the two strands of wire rope are placed side by side in the fixing sleeve 13, and then the mold assembly 3 is driven by the lower hydraulic press 5 to move upward to squeeze the fixing sleeve 13. During the extrusion process, the two strands of wire rope are fixed by the fixing assembly 4 to reduce the deformation of the wire rope during extrusion, thereby reducing the stress change in the temporal part of the wire rope.

[0042] As an embodiment of the present invention, refer to Figure 3 and Figure 4The mold assembly 3 includes a fixed seat 31, a lower mold 32, a fixed plate 33, an upper mold 34, and a fixed column 35. The fixed seat 31 is installed on the top of the lower hydraulic press 5, and is movably connected to the connecting hole 11, and extends through the connecting hole 11 to the outside of the connecting hole 11. The fixed seat 31 is installed on the top of the lower hydraulic press 5, and the lower mold 32 and the fixed assembly 4 are both installed on the top of the fixed seat 31, and the fixed assembly 4 is located on the top of the lower mold 32. The left and right sides of the fixed seat 31 are provided with a first slide groove 311, and the first slide block 312 is slidably connected inside the first slide groove 311. The fixed plate 33 is connected to the first slide block 312, and the bottom of the first slide block 312 is connected to a second spring 313. When the extrusion starts, the fixed plate 33 moves downward, thereby driving the fixed sleeve 13 to move downward so that the fixed sleeve 13 contacts the lower mold 32. When the extrusion is completed, the first slide block 312 is pushed to move by the second spring 313, so that the fixed plate 33 is reset. The fixing column 35 is installed on the top of the inner wall of the support frame 2, and the upper mold 34 is installed on the bottom of the fixing column 35. The top of the lower mold 32 and the top of the upper mold 34 are both provided with a lower rectangular slot 36. The width of the rectangular slot 36 is the same as that of the fixing sleeve 13, so that the fixing sleeve 13 can be horizontally placed inside the rectangular slot 36, avoiding the phenomenon that the fixing sleeve 13 moves forward and backward during the extrusion process, thereby affecting the firmness of the fixation;

[0043] A top block 37 is connected to the bottom of the inner wall of the rectangular slot 36. When the two steel wires are attached, there is a gap between the attachment point and the inner wall of the fixed sleeve 13. The top block 37 is used to squeeze the middle between the top and bottom of the fixed sleeve 13 to eliminate the gap. The cross-section of the top block 37 is set to a pentagon, and the two oblique sides 372 of the top block 37 are set to an arc. The top block 37 squeezes the bottom and top of the inner wall of the fixed sleeve 13 into an arc, so that the inner wall of the fixed sleeve 13 can better fit the outer wall of the wire rope. A fixing block 331 is connected to the top of the fixing plate 33, and a side hydraulic press 332 is fixedly connected to the top of the fixing block 331. A pressing block 333 is connected to the extended end of the side hydraulic press 332. An arc-shaped slot 334 is provided on the pressing block 333 near the side of the lower mold 32. When the upper mold 34 and the lower mold 32 squeeze the fixing sleeve 13, the side hydraulic presses 332 on the left and right sides drive the pressing block 333 to move and compact the side of the fixing sleeve 13, so that the fixing sleeve 13 and the steel wire rope are compacted and the steel wire ropes are fitted together.

[0044] As an embodiment of the present invention, refer to Figure 4A fixing block 331 is connected to the top of the fixing plate 33, and a side hydraulic press 332 is fixedly connected to the top of the fixing block 331. The side hydraulic press 332 is fixedly connected to the top of the fixing block 331, and a pressing block 333 is connected to the extended end of the side hydraulic press 332. An arc-shaped groove 334 is opened on the side of the pressing block 333 close to the lower mold 32, and the arc-shaped groove 334 fits with the left and right outer walls of the fixing sleeve 13, so that the inner wall of the fixing sleeve 13 maintains an arc shape when the fixing sleeve 13 is squeezed, so that the inner walls of the left and right sides of the fixing sleeve 13 are better fitted with the outer wall of the wire rope, and the side hydraulic presses 332 on the left and right sides drive the pressing block 333 to move to compact the side of the fixing sleeve 13, so that the fixing sleeve 13 fits with the wire rope while also fitting the wire ropes together. The width of the pressing block 333 is equal to that of the rectangular slot 36, so that the pressing block 333 fits the inner wall of the rectangular slot 36, thereby reducing the gap generated during the extrusion process, and the vertical length of the first straight side 3341 of the arc-shaped slot 334 is equal to the second straight side 371 of the top block 37, and the annular inner wall formed by the arc-shaped slot 334 on one side of the pressing block 333 and the outer wall top of the top block 37 is smooth, thereby reducing the gap between the wire rope and the fixed sleeve 13 during extrusion.

[0045] As an embodiment of the present invention, refer to Figure 5 The fixing assembly 4 includes a moving block 41, a clamping plate 42, and a baffle 43. A second slide groove 321 is provided at the top of the lower mold 32. A second slider 322 is connected inside the second slide groove 321. The top of the second slider 322 is connected to the bottom of the moving block 41. The second slider 322 drives the moving block 41 to move in the second slide groove 321, so that the moving block 41 moves to a desired position, so that the arc groove 421 on the moving block 41 better fits the outer wall of the wire rope. The top of the moving block 41 is provided with a first Groove 411, a clamping plate 42 is connected inside the first groove 411, a threaded hole 412 is opened on the right side of the moving block 41, a threaded rod 413 is connected inside the threaded hole 412, the right end of the threaded rod 413 is connected to the clamping plate 42, and the left end of the threaded rod 413 is connected to the crank 414. When the steel wire passes through the fixing sleeve 13 and is bent, it passes between the clamping plate 42 and the left inner wall of the first groove 411, and then the crank 414 is shaken to move the clamping plate 42 toward the left inner wall of the first groove 411, thereby fixing the steel wire rope. The opposite surfaces of the moving block 41 and the clamping plate 42 are both opened with an arc groove 421. The inner wall of the arc groove 421 is twisted and has the same shape as the outer wall of the steel wire rope. The arc groove 421 is used to fit the outer wall of the steel wire rope, thereby maintaining the structural stability of the steel wire rope itself, thereby reducing the appearance of loose strands. The baffle 43 is installed on the top of the lower mold 32.

[0046] As an embodiment of the present invention, refer to Figure 6 and Figure 7A sliding hole 351 is provided at the bottom of the fixed column 35, and a first spring 352 is connected to the top of the sliding hole 351. A sliding block 353 is connected to the bottom of the first spring 352. The sliding block 353 slides inside the sliding hole 351, and the bottom of the initial position extends to the outside of the sliding hole 351. A second groove 354 is provided at the bottom of the sliding block 353 and the top of the clamping block 355. The vertical center lines of the two second grooves 354 are on the same straight line, and the inner wall of the second groove 354 has the same shape as the outer wall of the wire rope. The wire rope first passes through the second groove 354 and then passes through the fixed sleeve 13. When the upper mold 34 moves upward, the bottom of the sliding block 353 fits with the top of the clamping block 355, so that the two second grooves 354 wrap the wire rope and fix the wire rope.

[0047] As an embodiment of the present invention, refer to Figure 7 and Figure 8 A second through hole 431 is provided on the front side of the baffle plate 43, a spiral groove 432 is provided on the inner wall of the second through hole 431, and a third slider 433 is connected to the inner wall of the spiral groove 432. A moving disk 44 is connected to the inside of the second through hole 431, and the outer wall of the moving disk 44 is connected to the third slider 433. A connecting groove 441 is provided on the rear side of the moving disk 44, and a chuck 45 is connected to the inside of the connecting groove 441 through a bearing. When the torsion of the wire rope is large, the chuck 45 is moved on the moving disk 4 4 to avoid excessive torque on the wire rope and thus causing damage. A flower groove 451 is provided on the rear side of the chuck 45, and the flower groove 451 fits with the end of the wire rope. After the wire rope is bent and passes through the fixing sleeve 13, the bent end of the wire rope is fitted with the rectangular clamping groove 36, thereby fixing the end of the wire rope to avoid loose strands during the extrusion process. When the wire rope pushes the chuck 45 to drive the movable plate 44 to move, the movable plate 44 follows the third slider 433 to rotate in the second through hole 431. Ratchet teeth 442 are provided on the inner wall of the connecting groove 441, and a plurality of elastic paddles 452 are connected to the outer wall of the chuck 45. The elastic paddles 452 cooperate with the ratchet teeth 442. Through the cooperation between the ratchet teeth 442 and the elastic paddles 452, the movable disk 44 drives the chuck 45 to rotate, so that the chuck 45 generates torque on the wire rope, increases the stress inside the wire rope, and further reduces the occurrence of loose strands. When the torque between the chuck 45 and the wire rope is large, the elastic paddles 452 are bent, so that the chuck 45 rotates unidirectionally in the movable disk 44, thereby avoiding damage to the wire rope due to excessive torque.

[0048] Working principle: Preparation stage: Refer to Figure 4 and Figure 5, first fit the fixing sleeve 13 with the arc-shaped groove 334 on one side of the pressure block 333, and then start the two side hydraulic presses 332 to push the two pressure blocks 333 close to each other to fix the fixing sleeve 13, then pass one end of the steel wire through the second groove 354 and the fixing sleeve 13 in turn, and bend the steel wire after passing through the fixing sleeve 13, and then pass it between the clamping plate 42 and the left inner wall of the first groove 411 after bending, and then shake the crank 414 to move the clamping plate 42 toward the left inner wall of the first groove 411, so that the arc groove 421 on the left side of the clamping plate 42 and the arc groove 421 on the moving block 41 are close to the steel wire rope. Because the interior of the arc groove 421 is twisted, the outer wall of the steel wire rope and the inner wall of the arc groove 421 can fit tightly when they are close to each other, thereby fixing the steel wire rope, and then pass the steel wire rope through the fixing sleeve 13, refer to Figure 7 Finally, the bent end of the wire rope is pressed against the chuck 45, so that the end of the wire rope is inserted into the flower groove 451 on the front side of the chuck 45, thereby fixing the end of the wire rope to prevent the end of the wire rope from being scattered during the extrusion process. Because the initial height of the fixing sleeve 13 is higher than the height of the chuck 45, the height of the wire rope at the fixing sleeve 13 is higher than the height of the end of the wire rope, so the wire rope is bent;

[0049] Working stage: Reference Figure 2 and Figure 4 , start the lower hydraulic press 5 to drive the lower mold 32 to move upward, so that the fixed sleeve 13 contacts the top block 37 at the bottom of the upper mold 34, and the lower hydraulic press 5 continues to rise. The top block 37 at the bottom of the upper mold 34 produces a downward thrust on the fixed sleeve 13, thereby pushing the fixed sleeve 13 to move downward, so that the bottom of the fixed sleeve 13 fits with the inner wall of the rectangular slot 36 at the top of the lower mold 32, and also drives the fixed plate 33 to move downward, and then start the two side hydraulic presses 332 again to push the pressing block 333 to squeeze the left and right sides of the fixed sleeve 13. At the same time, the lower mold 32, under the push of the lower hydraulic press 5, squeezes the fixed sleeve 13 up and down together with the upper mold 34. During the extrusion process, there is a certain gap between the fitting part of the two steel wire ropes and the top and bottom of the inner wall of the fixed sleeve 13. Figure 3 and Figure 4 The middle part of the fixing sleeve 13 is squeezed by the top block 37 inside the rectangular slot 36 in the lower mold 32 and the upper mold 34, thereby eliminating the gap between the two strands of steel wire ropes and the top and bottom of the inner wall of the fixing sleeve 13, and increasing the tightness between the steel wire rope and the fixing sleeve 13. When the first straight edge 3341 contacts the second straight edge 371, the extrusion is completed. Because the first straight edge 3341 and the second straight edge 371 have the same vertical length, the arc-shaped slot 334 on one side of the pressing block 333 and the top of the outer wall of the top block 37 form a ring with a smooth inner wall, thereby reducing the gap between the steel wire rope and the fixing sleeve 13 during extrusion. During the extrusion process, the steel wire rope changes from a curved state to a vertical state, and the end portion will extend forward at this time. Figure 7 and Figure 8Because the inner wall of the second through hole 431 opened on the front side of the baffle 43 is provided with a spiral groove 432, when the steel wire pushes the chuck 45 to drive the movable plate 44 to move, the movable plate 44 follows the third slider 433 to rotate in the second through hole 431, and through the cooperation of the ratchet teeth 442 and the elastic paddle 452, the movable plate 44 drives the chuck 45 to rotate, so that the chuck 45 generates a torque on the end of the steel wire rope, increases the stress inside the steel wire rope, and further reduces the occurrence of loose strands. When the torque between the chuck 45 and the end of the steel wire rope is large, the elastic paddle 452 is bent, and the chuck 45 rotates in the movable plate 44 to avoid the steel wire rope being damaged by excessive torque.

[0050] Ending stage: When the extrusion is completed, the lower hydraulic press 5 is started to retract, and the fixed plate 33 moves upward and returns to its original position under the push of the second spring 313. Figure 5 and Figure 7 Then, the crank 414 is turned to separate the clamping plate 42 from the wire rope, thereby releasing the fixation of the wire rope. Then, the side hydraulic press 332 is started to contract, thereby releasing the fixation of the fixing sleeve 13. Finally, the end of the wire rope is pulled out of the flower groove 451 to remove the pressed wire rope ring.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
