Description

Technical Field

[0001] The invention relates to alloy plating technology, in particular to an alloy plating device. Background Art

[0002] In order to ensure the corrosion resistance of alloy materials and extend the service life of alloy materials, the alloy surface is usually plated. The general coating materials are: zinc, nickel and chromium. Among them, hot-dip galvanizing is the most widely used and cost-effective alloy surface treatment method in the world today. Hot-dip galvanizing is a process technology that immerses parts made of alloy materials into molten liquid metal to obtain a coating. Hot-dip galvanizing technology usually includes the following steps: surface cleaning, pretreatment, melting of coating materials, hot-dip plating, cooling and cleaning.

[0003] For example, the invention patent with the authorization announcement number CN115323305B and the authorization announcement date January 20, 2023, entitled "A galvanizing production process for hot-dip galvanized steel pipes", includes the following steps: Step 1, pretreatment of steel pipes: clean the steel pipes to be hot-dip galvanized to remove impurities and grease on the surface; Step 2, pickling of steel pipes: pickling the cleaned steel pipes, and drying the steel pipes after pickling after removing the residual acid on the surface through water flow; Step 3, immersion in plating agent: immerse the pickled steel pipes in plating agent, and then dry and preheat again; Step 4, hot-dip galvanizing: immerse the steel pipes in the galvanizing device for galvanizing. This device is provided with a toggle plate, so that when the steel pipe passes through the galvanizing liquid surface during the lifting process, the solidified galvanizing liquid on the liquid surface is pushed away, which is conducive to avoiding the adhesion of solidified blocks of galvanizing liquid to the steel pipe surface when it passes through the galvanizing liquid surface, thereby avoiding the adhesion of solidified blocks of galvanizing liquid to the steel pipe surface and affecting the galvanizing quality of the steel pipe.

[0004] For example, the authorization announcement number is CN110804719B, the authorization announcement date is October 12, 2021, and the name is an invention patent for a hot-dip galvanizing hanger, including side panels, a first motor, a chain, a load-bearing plate, a square cover, a bar hole, a T-block, a clamping block, an adjusting screw, a rectangular block, a gear, a single groove wheel, a rotating shaft, a box cover, a second motor, a bar slide, a screw hole, a stud, a wire rope, a winding wheel and a hollow shaft magnetic powder brake. The present invention changes the traditional hanger structure used in the hot-dip galvanizing process, adopts the method of winding up the steel wire rope to drive the lifting of the plated parts, and can form a continuous operation of entering the plated part pool, immersing the plated parts and lifting the plated parts through the intermittent and staggered operation between multiple winding steel wire ropes, so as to achieve the effect of orderly hot-dip galvanizing of the workpieces, solve the problem of cumbersome, time-consuming and labor-intensive transportation, and improve the work efficiency of the workshop. The corresponding part of the plated part is located between the two clamping blocks and the corresponding adjusting screw is rotated to push the corresponding clamping block to clamp and fix the plated part, so that the plated part can be clamped with strong firmness, which is convenient for subsequent lifting and other process operations.

[0005] For long strip workpieces, in order to improve the galvanizing efficiency, multiple workpieces are generally hoisted together and then slowly immersed in a zinc bath in an inclined posture. However, when the plated workpieces leave the zinc bath in an inclined posture, some zinc liquid will flow on the workpieces and gather at the lowest point of the plated parts and then drip. In the prior art, since multiple workpieces are in contact with each other, in order to prevent the zinc liquid on the upper workpiece from dripping on the lower workpiece and quickly cooling to form joints or protrusions, it is necessary to manually clean the zinc liquid accumulation at the lowest point of the workpiece. Summary of the Invention

[0006] The purpose of the present invention is to provide a plating alloy device to solve the above deficiencies in the prior art.

[0007] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0008] A plating alloy device includes a moving top plate, on which a plurality of mounting brackets for mounting workpieces are slidably installed. Each mounting bracket is formed with a pressing block, and the lengths of the pressing blocks increase sequentially from top to bottom to form a stepped shape as a whole. It also includes an arc-shaped convex block rotatably installed in the middle of the moving top plate; when the arc-shaped convex block rotates, it sequentially presses the plurality of pressing blocks to stagger the plurality of mounting brackets.

[0009] In the above plating alloy device, the mounting bracket is C-shaped with the opening facing downwards, and the mounting bracket is composed of a horizontal section and two vertical sections. The horizontal section is slidably installed on the moving top plate.

[0010] In the above plating alloy device, a limiting and mounting component is installed at the lower end of the vertical section, and the limiting and mounting component is used for mounting the workpiece. The limiting and mounting component includes a mounting circular plate, and a plurality of elastic limiting shafts are fixed on the mounting circular plate.

[0011] In the above plating alloy device, a plurality of spring rods are fixed on the moving top plate, and the movable sections of the spring rods correspond to the mounting brackets one by one and are fixedly connected together.

[0012] In the above plating alloy device, the arc-shaped convex block is rotatably connected to the middle of the moving top plate through a rotating shaft.

[0013] In the above plating alloy device, a driving component is installed on the moving top plate, and the driving component is used to drive the rotating shaft to rotate.

[0014] In the above plating alloy device, the driving component includes a servo motor, and the output shaft of the servo motor is detachably fixedly connected to the top of the rotating shaft.

[0015] The above-mentioned alloy plating device also includes a liquid storage tank, which is filled with the liquid to be plated. The liquid storage tank is located below the movable top plate. The width of the liquid storage tank is smaller than the width of the movable top plate. The liquid storage tank is detachably fixed on the ground.

[0018] In the above technical scheme, the present invention provides an alloy plating device, including a mounting bracket for mounting a workpiece. When the workpiece is immersed in a zinc liquid pool for a period of time, the movable top plate is moved upward. At this time, the arc-shaped protrusion is driven to rotate, and the arc-shaped protrusion will press the extrusion block to move outward from bottom to top in sequence, so that the mounting bracket can move outward from top to bottom in sequence, so that there is a certain distance between adjacent workpieces, that is, multiple workpieces are staggered. In this way, even if zinc liquid drips on the upper workpiece, it will not drip on the lower workpiece, reducing the cleaning steps of the staff and improving work efficiency.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-10 As shown, an embodiment of the present invention provides an alloy plating device, including a movable top plate 1, on which a plurality of mounting brackets 2 for mounting workpieces are slidably mounted, and an extrusion block 21 is formed on each of the mounting brackets 2. The length of each of the extrusion blocks 21 increases sequentially from top to bottom to form a stepped shape as a whole, and also includes an arc-shaped protrusion 3 rotatably mounted in the middle of the movable top plate 1; when the arc-shaped protrusion 3 rotates, the plurality of extrusion blocks 21 are pressed in turn so that the plurality of mounting brackets 2 are staggered.

[0034] Specifically in this embodiment, it should be noted that the workpiece to be plated in this embodiment is a strip-shaped workpiece, which is also the most common workpiece, such as steel pipes or I-beams, etc.; the moving top plate 1 is a square plate, and an external driving device can drive the moving top plate 1 to move up and down in the vertical direction, thereby driving the mounting bracket 2 and the workpiece to move in the vertical direction. The mounting bracket 2 is used to mount the workpiece, and the mounting position of the workpiece is at the lower end of the mounting bracket 2. The mounting bracket 2 is preferably in a U-shape with the opening facing downwards. The shapes of multiple mounting brackets 2 are the same but their sizes (length and width) are different. Counting from top to bottom, the sizes of the mounting brackets 2 gradually decrease. Such a setting of multiple mounting brackets 2 is to avoid interference between the mounting brackets 2 during liquid discharge; the mounting bracket 2 has two working mode states. One is the plating solution mode (the workpiece is being plated with zinc solution), and at this time, multiple mounting brackets 2 can be stacked together in sequence from top to bottom and are in the same vertical plane. In this way, the central axes of the workpieces are also in the same vertical plane, reducing the space volume occupied by multiple workpieces and facilitating the plating solution. The other is the liquid discharge mode (the workpiece plating is completed), and at this time, the mounting brackets 2 are not in the same plane. In this way, the central axes of the workpieces are not in the same vertical plane either, and there is a certain distance between adjacent workpieces, so that the zinc solution on the upper workpiece will not drip onto the surface of the lower workpiece again. The extrusion block 21 is preferably a square block, and the lengths of the extrusion blocks 21 increase in sequence from top to bottom, and multiple extrusion blocks 21 are integrally in a stepped shape; the arc-shaped convex block 3 is preferably a block structure with one end face being an arc surface. In the liquid discharge mode, when the arc-shaped convex block 3 rotates, the arc surface end of the arc-shaped convex block 3 will first contact the lowermost extrusion block 21; the shortest distance between the extrusion block 21 and the arc-shaped convex block 3 decreases in sequence from top to bottom. When the arc-shaped convex block 3 rotates (defining this rotation direction as the positive direction), the arc surface section of the arc-shaped convex block 3 will first contact and extrude the lowermost extrusion block 21 to slide outwards. The arc-shaped convex block 3 continues to rotate to sequentially extrude multiple extrusion blocks 21 to move outwards. At this time, the mounting brackets 2 move outwards in sequence from top to bottom, and the moving distances of each mounting bracket 2 are inconsistent. In this way, the adjacent mounting brackets 2 are staggered.

[0035] Specifically during operation, after the workpiece is immersed in the plating solution, an external driving device drives the moving top plate 1 to move upward. At the same time, the arc-shaped convex block 3 is synchronously driven to move. The arc-shaped convex block 3 sequentially presses multiple extrusion blocks 21 to move outward, causing the mounting brackets 2 to also move downward in sequence from top to bottom. Specifically for each mounting bracket 2, that is, the mounting bracket 2 that first leaves (the uppermost) the zinc solution moves outward. In this way, multiple mounting brackets 2 move outward by a certain distance in sequence from top to bottom, and multiple workpieces also move outward synchronously from top to bottom, so that there is a certain distance between adjacent workpieces, that is, the multiple workpieces are staggered. Even if there is zinc solution dripping on the upper workpiece, it will not drip on the lower workpiece, reducing the cleaning steps of the staff and improving the work efficiency.

[0036] In another embodiment provided by the present invention, the mounting bracket 2 is in a C shape with an opening facing downward. The mounting bracket 2 is composed of a horizontal section 22 and two vertical sections 23. The horizontal section 22 is slidably mounted on the moving top plate 1. In the plating solution mode, the horizontal sections 22 are stacked together in the vertical direction, and the lengths of multiple horizontal sections 22 decrease sequentially from top to bottom. This is to facilitate the movement of the vertical sections 23. In this embodiment, the higher the horizontal height of the horizontal section 22, the longer the length of the vertical section 23 mounted thereon, so that the workpieces can be at different horizontal heights, and the workpieces are three-dimensionally distributed, which can make full use of the space and at the same time protect the workpieces from contacting each other and avoid movement interference.

[0037] In another embodiment provided by the present invention, a limiting and mounting component 24 is connected to the lower end of the vertical section 23. The limiting and mounting component 24 is used for mounting workpieces. There are various technical solutions in the prior art for mounting workpieces. For strip-shaped workpieces with a certain length, this embodiment provides a preferred workpiece mounting structure. The limiting and mounting component 24 preferably includes a mounting circular plate 241, and multiple elastic limiting shafts 242 are fixed on the mounting circular plate 241. The elastic limiting shafts 242 can perform a certain degree of elastic expansion and contraction. When it is necessary to mount a strip-shaped workpiece with a specific length, the elastic limiting shafts 242 can be inwardly squeezed to cause a certain deformation, and then the strip-shaped workpiece is mounted, so that the strip-shaped workpiece is limited between the mounting circular plates 241. Of course, the limiting and mounting component 24 in this embodiment is not limited to this specific structure. For mounting workpieces with different structures, those skilled in the art have reasons to replace the above elastic limiting shafts 242 with other specific structures.

[0038] Preferably, in the prior art, the workpiece is generally installed by hoisting. In the present invention, it can also be directly hoisted at the lower end of the vertical section 23. Hoisting can reduce the volume of additional components entering the plating solution and avoid wasting the plating solution. To this end, the structure of the mounting bracket 2 can be further improved: the horizontal section 22 is a plate with a strip structure, and the vertical section 23 is a steel wire rope. The bottom of the steel wire rope is provided with multiple sections, which can be connected to the workpiece by winding or passing through the hole of the workpiece. In this way, the installation of the workpiece can also be achieved.

[0039] In another embodiment provided by the present invention, a plurality of spring rods 25 are fixed on the movable top plate 1, and the movable sections of the spring rods 25 correspond to the mounting bracket 2 one by one and are fixedly connected together. The spring rods 25 are used to maintain the position of the mounting bracket 2 on the movable top plate 1, so that the mounting bracket 2 can be reset after moving, which is convenient for the reuse of the mounting bracket 2. When the arc-shaped protrusion 3 rotates and sequentially presses the plurality of extrusion blocks 21 to move outward from bottom to top, the mounting bracket 2 will also move accordingly and squeeze the spring rods 25. When the arc-shaped protrusion 3 is reset, the mounting bracket 2 is also reset in time under the elastic action of the spring rods 25.

[0040] In another embodiment provided by the present invention, the arc-shaped protrusion 3 is rotatably connected to the middle part of the movable top plate 1 via a rotating shaft 31 , and the rotating shaft 31 provides an installation position for the arc-shaped protrusion 3 .

[0041] In another embodiment provided by the present invention, a driving assembly 32 is installed on the movable top plate 1, and the driving assembly 32 is used to drive the rotating shaft 31 to rotate.

[0042] In another embodiment provided by the present invention, see Figure 1 The driving assembly 32 includes a servo motor 321, and the output shaft of the servo motor 321 is detachably fixed to the top of the rotating shaft 31. In this embodiment, the rotation of the rotating shaft 31 is controlled by starting and shutting down the servo motor 321, thereby controlling the rotation of the arc-shaped protrusion 3 and the movement of the mounting bracket 2.

[0043] In another embodiment provided by the present invention, it also includes a liquid reservoir 4, the liquid reservoir 4 is filled with the liquid to be plated, and the liquid to be plated is preferably zinc liquid. The liquid reservoir 4 is located below the movable top plate 1, and the width of the liquid reservoir 4 is smaller than the width of the movable top plate 1. The liquid reservoir 4 is detachably fixed on the ground, and the movable top plate 1 is controlled to move downward so that the movable top plate 1 drives the workpiece into the liquid reservoir 4, and the movable top plate 1 is controlled to move upward so that the movable top plate 1 drives the workpiece out of the liquid reservoir 4. The main function of the liquid reservoir 4 is to store high-temperature liquid to be plated, which is convenient for alloy plating.

[0044] In another embodiment provided by the present invention, see Figure 3 and Figure 4 The driving assembly 32 includes a first bevel gear 322 fixed to the top of the rotating shaft 31, and a first driving shaft 323 is rotatably installed on the movable top plate 1, one end of the first driving shaft 323 is fixedly connected to a second bevel gear 324, the second bevel gear 324 and the first bevel gear 322 are meshed with each other, and the other end of the first driving shaft 323 is fixedly connected to a driving gear 325, and a rack 326 is fixedly provided on the side wall of the liquid reservoir 4, and the driving gear 325 and the rack 326 are meshed with each other; specifically, when the movable top plate 1 moves upward to drive the workpiece to leave the liquid reservoir 4, the driving gear 325 also moves upward, and because the driving gear 325 and the rack 326 are meshed with each other and the rack 326 is in a fixed state, the driving gear 325 moves upward. Rotation also occurs during the movement, and the rotation of the driving gear 325 drives the first driving shaft 323 to rotate synchronously, and the second bevel gear 324 rotates accordingly and drives the first bevel gear 322 and the rotating shaft 31 to rotate forwardly, so that the mounting bracket 2 can move outward from top to bottom in sequence; similarly, when the movable top plate 1 moves downward and drives the workpiece to enter the liquid storage tank 4, the driving component 32 can make the mounting bracket 2 retract inward from bottom to top in sequence and drive the workpiece to be arranged in a vertical direction; in this way, through the driving component 32, when the workpiece enters the liquid storage tank 4, the workpieces can be retracted one by one and arranged vertically, and when the workpiece leaves the liquid storage tank 4, the workpieces can move outward one by one and staggered, and the movement of the rotating shaft 31 has no active power, and there is no need to set up a separate power source. It is completely passive and meets the working requirements.

[0045] It should be noted that in a complete galvanizing process, the workpiece has three working states. The first is the preparatory state. At this time, the mounting bracket 2 is completely outside the liquid reservoir 4, and the workpiece can be installed on the mounting bracket 2; the second is the plating state. The mounting bracket 2 drives the workpiece to be located in the liquid reservoir 4, and the plating liquid is coating the workpiece; the third is the subsequent processing state. At this time, the workpieces that have been plated are staggered one by one and leave the liquid reservoir 4; in the preparatory state, the mounting bracket 2 is also in a staggered state. At this time, it is also helpful to install the workpiece to avoid collision between the workpieces during the installation process.

[0046] In another embodiment provided by the present invention, it also includes a set of lifting equipment (not shown in the figure), which is lifted together with the movable top plate 1. The lifting equipment is used to control the up and down movement of the movable top plate 1. There are many devices in the prior art that can drive the movable top plate 1 to move in the vertical direction, which will not be elaborated here.

[0047] More preferably, in the actual working process, since the length of the liquid storage tank 4 is generally greater than the length of the workpiece, it is possible to drive the movable top plate 1 to move even through a lifting device. This is because the requirement for the movement accuracy of the workpiece is relatively low. However, in the above embodiment, the driving gear 325 and the rack 326 need to cooperate with each other. Therefore, the more preferred installation position of the rack 326 is to install it on a lifting device, such as a crane, so as to ensure that the driving gear 325 and the rack 326 can be used stably.

[0048] In the prior art, the workpiece is usually allowed to gradually enter the liquid reservoir 4 in an inclined state. This is to prevent the workpiece from directly and quickly contacting the zinc liquid as a whole and causing the zinc liquid to boil. In order to make the workpiece tilt, the prior art generally uses steel wire ropes of different lengths to suspend the workpiece. However, after the workpiece tilts into the liquid reservoir 4, it still maintains its original inclined state to leave the liquid reservoir 4, which results in the downwardly inclined end of the workpiece contacting the plating liquid first and then leaving the liquid reservoir 4. In this way, the downwardly inclined end of the workpiece will be in the liquid reservoir 4 for a longer time than the upwardly inclined end of the workpiece, resulting in inconsistent coating thickness on the workpiece. In the prior art, the lifting steel wire is directly connected to the crane and can be freely controlled to be retracted and released. However, in the present application, the workpiece is installed or hoisted on the mounting bracket 2, which cannot be freely retracted and released. This results in the inability to achieve the above-mentioned tilt change of the workpiece that can be controlled in the prior art. Therefore, based on the above-mentioned technical problem, an improvement plan is proposed: further improve the movable top plate 1 so that the workpiece can smoothly enter the liquid reservoir 4 in an inclined state. See FIG. Figure 6 and Figure 7, including a square mounting member 11, the square mounting member 11 is located above the movable top plate 1, a first through hole is opened on the side of the middle of the movable top plate 1 close to the driving gear 325, and a second through hole is opened on the side of the middle of the movable top plate 1 away from the driving gear 325, a first connecting rope 14 is slidably penetrated in the first through hole, and a second connecting rope 15 is slidably penetrated in the second through hole, the lower end of the first connecting rope 14 is detachably fixed to one end of the movable top plate 1, and the lower end of the second connecting rope 15 is detachably fixed to the other end of the movable top plate 1, a winding assembly (not shown in the figure) is installed on the upper end of the square mounting member 11, the first connecting rope 14 and the second connecting rope 15 are both connected to the winding assembly, and the winding assembly can respectively control the first connecting rope 14 and the second connecting rope 15 to be wound separately Winding or unwinding, it is particularly important to explain that, in the present embodiment, the lifting equipment no longer lifts the movable top plate 1, but lifts the square mounting piece 11, so that the inclination of the movable top plate 1 can be controlled; specifically, taking the winding of the first connecting rope 14 as an example, when the workpiece is mounted on the mounting bracket 2, the winding assembly controls the winding of the first connecting rope 14 and simultaneously controls the unwinding of the second connecting rope 15. At this time, the end of the movable top plate 1 close to the driving gear 325 moves upward, and the end of the movable top plate 1 away from the driving gear 325 moves downward, so that the movable top plate 1 is inclined, and then the square mounting piece 11 is driven downward by the lifting equipment, so that the workpiece enters the liquid storage tank 4 in an inclined state; similarly, the second connecting rope 15 can be wound up and the first connecting rope 14 can be unwound, and the workpiece will be in an inclined state opposite to the above.

[0049] For further information, see Figure 6 and Figure 7In this embodiment, the first drive shaft 323 is fixed on the square mounting member 11, and the first bevel gear 322 and the second bevel gear 324 are also located above the square mounting member 11. This is another embodiment different from the aforementioned embodiment. Such design is also for the purpose of facilitating the tilting of the workpiece. The winding assembly includes an elastic telescopic rod 51 fixedly connected to the rotating shaft 31, and a universal joint 52 is fixedly connected to the upper end of the elastic telescopic rod 51. The universal joint 52 is used to change the direction of power transmission. The universal joint 52 is the prior art and is not described here. A connecting shaft 53 is rotatably penetrated in the middle part of the square mounting member 11, and the universal joint 52 is connected to the lower end of the connecting shaft 53. It should also be noted that in this embodiment, the first bevel gear 322 is fixedly connected to the upper end of the connecting shaft 53 instead of the upper end of the rotating shaft 31. The universal joint 52 and the elastic telescopic rod 51 are designed to make the movable top plate 1 and the square mounting member 1 rotate. When relative displacement occurs between the mounting parts 11, the connecting shaft 53 can still drive the rotating shaft 31 to rotate, and the second driving shaft 54 ​​is also rotatably installed on the upper end of the square mounting part 11, and the axis of the second driving shaft 54 ​​coincides with the axis of the first driving shaft 323, and one end of the second driving shaft 54 ​​is fixedly connected to the third bevel gear 55, and the third bevel gear 55 and the first bevel gear 322 are meshed with each other. In this way, when the first bevel gear 322 rotates, since the second bevel gear 324 and the third bevel gear 55 are respectively located on the two sides opposite to the first bevel gear 322, the rotation directions of the second bevel gear 324 and the third bevel gear 55 are opposite; a first winding wheel 56 is fixedly connected to the first driving shaft 323, and the upper end of the first connecting rope 14 is wound on the first winding wheel 56, and a second winding wheel 57 is fixedly connected to the second driving shaft 54, and the second connecting rope 15 is wound on the second winding wheel 57.

[0050] Specifically, taking the winding of the first connecting rope 14 as an example, when the square mounting member 11 moves downward, the driving gear 325 is driven and rotated by the rack 326. At this time, the first driving shaft 323 rotates accordingly, and the first winding wheel 56 rotates synchronously and drives the first connecting rope 14 to be wound on the first winding wheel 56. At the same time, the rotation of the first driving shaft 323 also drives the second bevel gear 324 to drive the first bevel gear 322 to rotate. At this time, the first bevel gear 322 also drives the third bevel gear 55 to rotate synchronously, and the second winding wheel 57 is driven by the third bevel gear 55 to rotate in the opposite direction and unwind the second connecting rope 15. In this way, The square mounting member 11 is in a tilted state, during which the elastic telescopic rod 51 is compressed and the universal joint 52 also undergoes certain changes, but this does not affect the power transmission from the first bevel gear 322 to the rotating shaft 31; in this way, when the square mounting member 11 moves downward, the workpiece can automatically complete the tilt and enter the liquid reservoir 4 for plating, and at this time, the end of the workpiece away from the driving gear 325 tilts downward and first enters the liquid reservoir 4 for plating. It can be seen from the above-mentioned multiple embodiments that the movement of the workpiece is a combination of multiple movements, including the movement of the workpiece as a whole in the vertical direction, the overall tilting of the workpiece, and the staggering or retraction of the workpieces one by one.

[0051] Similarly, when the square mounting member 11 moves upward, the driving gear 325 will rotate in the opposite direction, that is, the mounting bracket 2 will tilt in the opposite direction, and the workpiece in the liquid reservoir 4 will also gradually tilt in the opposite direction at this time, so that the end of the workpiece away from the driving gear 325 tilts upward and leaves the liquid reservoir 4 first, so that the end of the workpiece away from the driving gear 325 enters and leaves first, and the end of the workpiece close to the driving gear 325 enters and leaves last, so that the plating time of the entire workpiece in the liquid reservoir 4 is roughly the same, thus improving the uniformity of the thickness of the film plated on the workpiece. Moreover, this function is naturally realized based on the need for the workpiece to tilt into the liquid reservoir 4, which has an unexpected effect.

[0052] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
