Description

Technical Field

[0001] This invention relates to the field of environmentally friendly conveying equipment technology, specifically a multi-point automatic dust removal environmentally friendly conveyor equipment. Background Technology

[0002] In mining operations, conveyors are typically used to transport ore. To ensure the conveying path is compatible with the site, multiple conveyors are usually used in combination to form an ore conveying line. (See attached instruction manual) Figure 14 As shown, this is a mining conveyor in the prior art. It has guide rollers 02 evenly distributed between the two side frames 03, and the conveyor belt 01 is wound around each guide roller 02. By driving the conveyor belt 01 to run around the guide rollers 02, the ore can be conveyed. The cross-section of the conveyor belt 01 is designed in a V shape, which can prevent the ore from falling off the side of the conveyor belt 01.

[0003] During the conveying of ore, especially at the transfer points between conveyor belts, dust is easily generated due to material falling and vibration during the conveying process. To prevent dust spillage, a cover is usually installed on the side frame 03 above the conveyor belt 01 to intercept and collect the dust. However, in the existing technology, the cover is usually fixed. When replacing or adjusting vulnerable parts in the conveying equipment, such as guide rollers 02, the cover needs to be removed and reinstalled to avoid obstructing operation. Removing and reinstalling the cover consumes a lot of time, is cumbersome, affects the maintenance efficiency of the ore conveying equipment, and leads to prolonged downtime for maintenance, affecting production progress. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-point automatic dust removal environmentally friendly conveyor equipment to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A multi-point automatic dust removal environmentally friendly conveyor equipment includes two side frames with guide rollers evenly distributed between them and a conveyor belt wound around the side frames. Several dust removal modules are arranged at intervals above the two side frames along the length of the conveyor belt. Each dust removal module consists of a first cover and a second cover in an inverted U-shape. One end of the second cover is slidably embedded in the first cover. A first suction pipe is connected to the first guide port on the top of each second cover. Each first suction pipe is connected to an external vacuum cleaner.

[0007] One of the side frames is equipped with an adjustment drive mechanism, which is used to drive the first cover and the second cover corresponding to each position to slide and adjust in opposite directions along the length of the conveyor belt. When each first cover and the corresponding second cover are adjusted to their extreme positions, each dust removal module is connected in sequence to form a dust collection hood with openings at both ends. A dust collection channel is formed between the dust collection hood and the top of the conveyor belt. When each first cover and the corresponding second cover are adjusted to be close to each other, a clearance space is formed between two adjacent dust removal modules.

[0008] Preferably, two supports are fixed to the side of the side frame away from the adjustment drive mechanism, and a guide rod is fixed between the two supports. A first slide is fixed to the side of each first cover via a connecting arm, and a second slide is fixed to the side of each second cover via a connecting arm. Each first slide and each second slide are slidably fitted onto the guide rod, and the bottom end face of each first cover and each second cover is slidably attached to the top surface of the side frame.

[0009] Preferably, each of the first covers is provided with a relief groove extending along the length of the conveyor belt at a position corresponding to the position of the first guide port, so that the first guide port can move within it. Each of the inner walls on both sides of the relief groove is provided with a receiving groove extending along the width of the conveyor belt. Each receiving groove is slidably installed with a sealing plate. The ends of the two sealing plates extending into the relief groove can be joined together completely to seal the relief groove.

[0010] Each of the two receiving slots has a first spring fixed on its inner end wall, which extends along the width of the conveyor belt. Each first spring is fixed to the side of the sealing plate. Both sealing plates have an arc-shaped notch that fits and conforms to the outer peripheral wall of the first guide port.

[0011] Preferably, a scraping dust removal mechanism is provided between the two side frames, located below the conveyor belt and near the downstream side of the conveyor belt. The scraping dust removal mechanism is used to clean and remove dust from the lower surface of the conveyor belt during the return trip. The scraping dust removal mechanism includes a U-shaped cover fixed between the two side frames, a box fixed inside the U-shaped cover with its opening facing upward, an airbag body installed on the box body, and a flexible scraper installed on the top of the airbag body.

[0012] The airbag is in an inflated state, and the shape of the flexible deformable surface at the top is adapted to the lower surface of the conveyor belt. The flexible scraper is detachably installed on the flexible deformable surface and slides against the lower surface of the conveyor belt. The second suction pipe is connected to the second guide port at the bottom of the U-shaped cover and is connected to an external vacuum cleaner.

[0013] Preferably, the airbag is fixed inside the box, and the box and the interior of the airbag together form an air chamber. The bottom of the box is connected to a cylinder, and a piston is slidably installed inside the cylinder. A vertically extending second spring is fixed on the bottom wall of the cylinder, and the top of the second spring is fixed to the lower surface of the piston.

[0014] Preferably, the adjustment drive mechanism includes a drive device and a transmission mechanism. The drive device is mounted on one of the side frames. The transmission mechanism includes a number of worm-type sleeves, shafts, and worm wheels that correspond one-to-one in number and position to each dust removal module. Each worm-type sleeve is mounted on the drive device. The drive device is used to drive each worm-type sleeve to rotate synchronously. The shafts are rotated one-to-one on the side of each first cover.

[0015] Each shaft is fixedly fitted with a worm gear and a gear. Each worm gear meshes with a corresponding worm-type sleeve. Each first cover has a second rack fixed to its side by a fixing block. Each second cover has a first rack fixed to its side by a fixing block. Both the first rack and the second rack mesh with their corresponding gears.

[0016] Preferably, the drive device includes a rotating shaft and a rocker plate. Mounting brackets are fixed on both sides of one side frame. The rotating shaft is rotatably mounted on the two mounting brackets. Each worm gear sleeve is respectively fitted on the rotating shaft. The rocker plate is mounted on one end of the rotating shaft.

[0017] Preferably, each worm gear sleeve is rotatably fitted with a support frame near both ends. A support plate is fixed between two support frames on the same worm gear sleeve. Each shaft passes through the corresponding support plate and is rotatably connected to the support plate. Each worm gear sleeve is slidably fitted on a rotating shaft. The outer wall of the rotating shaft has positioning ribs extending along its length. Each worm gear sleeve has a sliding groove on its inner edge wall. The positioning ribs are correspondingly matched and slidably engaged in each sliding groove.

[0018] Preferably, the outer wall of the second cover slides and fits into the inner wall of the first cover.

[0019] Preferably, the side end of the first cover is in contact with the side end of the second cover in the adjacent dust removal module.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0021] The dust collection hood is formed by connecting several dust removal modules, and the first cover and the second cover in each dust removal module can slide and adjust relative to each other. When the first cover and the corresponding second cover are adjusted closer to each other, a clearance space is formed between the two adjacent dust removal modules. Without dismantling and reinstalling the dust removal structure, the equipment parts can be easily replaced or maintained. The replacement and maintenance operation is efficient and the downtime is short, thereby improving production efficiency.

[0022] The worm gear sleeve can slide and adjust along the shaft, driving each dust removal module and corresponding transmission mechanism to slide as a whole. It can adjust the position and size of the clearance space and flexibly adapt to the maintenance needs of components in different positions.

[0023] As the first and second covers move further apart to their limits, the side end of the first cover engages with the side end of the second cover in the adjacent dust removal module. After adjustment, the dust removal module can adaptively reset to form a dust collection cover, eliminating the need for manual adjustment of each cover individually, saving operation time. Furthermore, the contact and fit ensure the sealing between adjacent dust removal modules, preventing dust leakage.

[0024] The flexible scraper strips are used to scrape and clean the dust adhering to the surface of the conveyor belt, peeling the dust off the surface of the conveyor belt. The peeled dust falls into the U-shaped cover and is sucked by the external vacuum cleaner through the second guide port and the second dust suction pipe. The dust collection cover and the first dust suction pipe above work together with the scraping dust removal mechanism below to achieve all-round collection of dust from the conveyor belt when transporting minerals, returning and transferring, thereby improving the environmental protection dust removal effect.

[0025] The airbag is in an inflated state, and the flexible deformable surface on top adapts to the surface under the conveyor belt. The flexible deformation of the airbag, combined with the buffer structure formed by the piston and the second spring, allows the flexible scraper to adapt and dynamically adjust to follow the shape fluctuations of the conveyor belt, continuously adhering to the surface under the conveyor belt and ensuring stable cleaning effect.

[0041] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0042] Example 1

[0043] Please see Figures 1-14 The present invention provides a multi-point automatic dust removal environmentally friendly conveyor equipment, including two side frames 03 with guide rollers 02 evenly distributed between them and a conveyor belt 01 wound around the side frames 03. The ore falls on the conveyor belt 01, and the ore can be conveyed downstream by driving the conveyor belt 01 to run around the guide rollers 02.

[0044] Several dust removal modules 1 are arranged at intervals above the two side frames 03 along the length of the conveyor belt 01. Each dust removal module 1 consists of a first cover 2 and a second cover 3. Both the first cover 2 and the second cover 3 have an inverted U-shaped structure. One end of the second cover 3 is slidably embedded in the first cover 2. Each second cover 3 has a first suction pipe 32 connected to the first guide port 31 at its top. Each first suction pipe 32 is connected to an external vacuum cleaner. The vacuum cleaner uses existing technology and is not shown in the figure.

[0045] By using an external vacuum cleaner to generate negative pressure, dust scattered on the conveyor belt 01 and at both ends of the conveyor belt 01 can be drawn into the dust storage area inside the vacuum cleaner through each first guide port 31 and the first suction pipe 32, thus achieving environmentally friendly dust removal during the transportation of mineral materials.

[0046] Two brackets 04 are fixed to the side of one side frame 03, and a guide rod 05 is fixed between the two brackets 04. The side of each first cover 2 is fixed with a first slide 06 through a connecting arm 08, and the side of each second cover 3 is fixed with a second slide 07 through a connecting arm 08. Each first slide 06 and each second slide 07 is slidably fitted onto the guide rod 05. By utilizing the sliding cooperation between the first slide 06 and the second slide 07 and the guide rod 05, each first cover 2 and each second cover 3 has the ability to slide along the length of the conveyor belt 01. In addition, the bottom end face of each first cover 2 and each second cover 3 is slidably attached to the top surface of the side frame 03 to prevent dust leakage and ensure dust removal effect.

[0047] On the other side frame 03, there is an adjustment drive mechanism 4. The adjustment drive mechanism 4 can drive the first cover 2 and the second cover 3 corresponding to each position to slide in opposite directions or in the opposite direction along the length of the conveyor belt 01. Specifically, the first cover 2 and the second cover 3 in each dust removal module 1 slide in opposite directions or in the opposite direction.

[0048] Among them, such as Figure 12 As shown, when each of the first covers 2 and the corresponding second covers 3 are adjusted to their extreme positions, each dust removal module 1 is connected in sequence to form a dust collection cover 09 with openings at both ends. A dust collection channel 11 is formed between the dust collection cover 09 and the top of the conveyor belt 01. When the vacuum cleaner is working, a negative pressure is formed in the dust collection channel 11, which can draw the air mixed with dust at the transfer points on both sides of the conveyor belt 01 into the dust collection channel 11 and extract it together with the dust floating on the conveyor belt 01, thereby achieving dust removal.

[0049] In addition, such as Figure 13As shown, when each of the first covers 2 and the corresponding second covers 3 are adjusted to be close to each other, that is, the second cover 3 slides into the first cover 2, forming a clearance space 12 between two adjacent dust removal modules 1, that is, forming a gap between two adjacent dust removal modules 1, which facilitates the replacement or maintenance of the components, so that the dust removal components do not need to be completely disassembled and reinstalled.

[0050] In summary, the dust collection hood 09 in this application is formed by connecting several dust removal modules 1, and the first cover 2 and the second cover 3 in each dust removal module 1 can slide and adjust relative to each other. When each first cover 2 and the corresponding second cover 3 are adjusted closer to each other, a clearance space 12 is formed between two adjacent dust removal modules 1. Without dismantling and reinstalling the dust removal structure, the equipment parts can be easily replaced or maintained. The replacement and maintenance operation is highly efficient, the downtime is short, and thus the production efficiency is improved.

[0051] Furthermore, the outer wall of the second cover 3 is slidably attached to the inner wall of the first cover 2, that is, the three outer walls of the second cover 3 are slidably attached to the three inner walls of the first cover 2 one by one. After long-term dust removal work, dust adheres to the inner walls of both the first cover 2 and the second cover 3. By adjusting the first cover 2 and the second cover 3 to be closer to each other, a clearance space 12 is formed between the two adjacent dust removal modules 1. When the second cover 3 retracts into the first cover 2, the dust on the inner wall of the first cover 2 can be scraped off because the second cover 3 is slidably attached to the inner wall of the first cover 2. In addition, the clearance space 12 makes it easy to clean the dust on the inner wall of the second cover 3 and the rest of the first cover 2.

[0052] The first suction pipe 32 is a flexible hose with bending and deformation capabilities, and a certain length is reserved to accommodate the positional changes of the second cover 3 during sliding adjustment.

[0053] Example 2

[0054] Please see Figure 3 , Figure 5 and Figure 6 The difference between this embodiment and Embodiment 1 is that:

[0055] The adjustment drive mechanism 4 includes a drive device 5 and a transmission mechanism 6. The drive device 5 is mounted on one of the side frames 03. The transmission mechanism 6 includes a number of worm-type sleeves 61, shafts 62 and worm wheels 63 that correspond one-to-one with each dust removal module 1. Each worm-type sleeve 61 is mounted on the drive device 5.

[0056] The shafts 62 are rotatably mounted on the sides of each first cover 2. Each shaft 62 is fixedly fitted with a worm gear 63 and a gear 64. Each worm gear 63 meshes with the corresponding worm sleeve 61. Each side of each first cover 2 is fixed with a second rack 66 by a fixing block 67. Each side of each second cover 3 is fixed with a first rack 65 by a fixing block 67. Both the first rack 65 and the second rack 66 mesh with the corresponding gear 64.

[0057] Specifically, the drive device 5 includes a rotating shaft 52 and a rocker plate 53. Mounting brackets 51 are fixed on both sides of a side frame 03. The rotating shaft 52 is rotatably mounted on the two mounting brackets 51. Each worm gear sleeve 61 is respectively fitted onto the rotating shaft 52. The rocker plate 53 is mounted on one end of the rotating shaft 52.

[0058] By shaking the rocker 53, the rotating shaft 52 is driven to rotate. The rotating shaft 52 can simultaneously drive each worm-type sleeve 61 to rotate. The rotating worm-type sleeve 61 meshes with the worm wheel 63 and drives the shaft 62 and gear 64 to rotate. Under the meshing transmission action of the rotating gear 64 with the first rack 65 and the second rack 66, the first cover 2 and the corresponding second cover 3 can be driven to slide and adjust in opposite directions, thereby realizing the retraction or extension adjustment of the dust removal module 1.

[0059] In addition, the worm gear sleeve 61 and worm wheel 63 achieve a self-locking effect through unidirectional transmission. When the rotating shaft 52 is not rotating for adjustment, the shaft 62 is prevented from rotating arbitrarily, which helps to maintain the position of the first cover 2 and the second cover 3 and prevents the first cover 2 and the second cover 3 from sliding arbitrarily.

[0060] Example 3

[0061] like Figure 6 and Figure 7 As shown, the difference between this embodiment and Embodiment Two is that:

[0062] Each worm gear sleeve 61 is rotatably fitted with a support frame 7 near both ends. A support plate 71 is fixed between two support frames 7 on the same worm gear sleeve 61. Each shaft 62 passes through the corresponding support plate 71 and is rotatably connected to the support plate 71. Since the shaft 62 is rotatably connected to the first cover 2, and combined with the connection between the shaft 62 and the support plate 71, the connection between the support plate 71 and the support frame 7, and the connection between the support frame 7 and the worm gear sleeve 61, the relative position of the transmission mechanism 6 and the first cover 2 is fixed, and the first rack 65 and the gear 64 are continuously engaged.

[0063] In addition, each worm gear sleeve 61 is slidably mounted on the rotating shaft 52. The outer wall of the rotating shaft 52 has a positioning rib 521 extending along its length. Each worm gear sleeve 61 has a groove 611 on its inner edge wall. The positioning rib 521 is correspondingly and slidably engaged in the groove 611. Thus, the worm gear sleeve 61 can slide and adjust along the surface of the rotating shaft 52. When the rotating shaft 52 rotates, the positioning effect of the positioning rib 521 engaged in the groove 611 ensures that the rotating shaft 52 can drive each worm gear sleeve 61 to rotate synchronously.

[0064] By utilizing the sliding adjustment feature of the worm gear sleeve 61 along the rotating shaft 52 and the sliding capability of the first cover 2 and the second cover 3, the entire assembly formed by each dust removal module 1 and the corresponding transmission mechanism 6 can be individually slidably adjusted along the length of the conveyor belt 01. This allows for adjustment of the position and size of the clearance space 12 formed between two adjacent dust removal modules 1, enabling replacement or maintenance of components at different positions with high flexibility.

[0065] Example 4

[0066] like Figure 12 As shown, the difference between this embodiment and Embodiment 3 is that:

[0067] The side end of the first cover 2 and the side end of the second cover 3 in the adjacent dust removal module 1 are in contact with each other, that is, the ends of the first cover 2 and the second cover 3 in the two adjacent dust removal modules 1 are in contact with each other, which plays a role in limiting and blocking.

[0068] After the components are replaced and maintained, and the first cover 2 and the second cover 3 are adjusted away from each other, the first cover 2 and the second cover 3 in the two adjacent dust removal modules 1 can naturally align and abut. The abutment at the corresponding points pushes each dust removal module 1 to move and adjust accordingly. There is no need to manually adjust the position of each dust removal module 1 one by one, so that the dust removal module 1 can self-adaptively reset to form the dust collection cover 09, saving operation time. In addition, by using the abutment and fit of the ends of the first cover 2 and the second cover 3 in the two adjacent dust removal modules 1, the sealing between the two adjacent dust removal modules 1 is ensured, and dust leakage is avoided.

[0069] Additionally, it is worth noting that when each dust removal module 1 resets to form the dust collection hood 09, that is, when the first cover 2 and the corresponding second cover 3 are moved away from each other to their extreme positions, such as Figure 2 As shown, the first slide 06 and the second slide 07 on the outermost side respectively abut against the second slide 07 on both sides to realize the automatic positioning of the dust collection hood 09 and ensure the accurate position of the dust collection hood 09.

[0070] Example 5

[0071] Please see Figure 4 , Figure 5 , Figure 8 and Figure 9 The difference between this embodiment and embodiment four is that:

[0072] Each of the first covers 2 is provided with a relief groove 21 extending along the length of the conveyor belt 01 at a position corresponding to the position of the first guide port 31, so that the first guide port 31 can move within it. That is, the relief groove 21 is used to make room for the movement of the first guide port 31, so as to avoid obstruction and interference to the first guide port 31 when the second cover 3 retracts into the first cover 2.

[0073] The inner walls on both sides of the relief groove 21 are provided with a collection groove 22 extending along the width of the conveyor belt 01. Each collection groove 22 is slidably installed with a sealing plate 23. The ends of the two sealing plates 23 extending into the relief groove 21 can be spliced ​​together to seal the relief groove 21 and prevent dust from leaking from the relief groove 21.

[0074] In addition, each of the two receiving slots 22 has a first spring 24 fixed on its opposite inner end wall, extending along the width direction of the conveyor belt 01. Each first spring 24 is fixed to the corresponding side of the sealing plate 23, such as... Figure 9 As shown, both sealing plates 23 have arc-shaped notches 231.

[0075] When the first cover 2 and the second cover 3 are far apart to their extreme positions, i.e., when the dust removal module 1 is fully extended, the elastic support force of the first spring 24 pushes the arc-shaped notches 231 on the two sealing plates 23 to match and fit against the outer peripheral wall of the first guide port 31, ensuring a high degree of fit between the sealing plate 23 and the first guide port 31, thus improving the dust leakage prevention effect. When the second cover 3 retracts into the first cover 2, the first guide port 31 moves into the relief groove 21, and the first guide port 31 pushes the sealing plate 23. The first spring 24 is compressed and stores force, and the sealing plate 23 retracts into the receiving groove 22, making room in the relief groove 21 so that the first guide port 31 can enter. When the first cover 2 and the second cover 3 are far apart to their extreme positions again, the elastic force of the first spring 24 pushes the sealing plate 23 to reset, so as to seal the relief groove 21 again.

[0076] In addition, the arc-shaped notch 231 has an arc-shaped structure design that can be guided and squeezed by the arc surface with the outer periphery of the first guide port 31, so that the first guide port 31 can push the two sealing plates 23 to the two sides respectively, avoiding jamming.

[0077] Example 6

[0078] Please see Figure 10 and Figure 11 The difference between this embodiment and Embodiment 5 is as follows:

[0079] A scraping dust removal mechanism 8 is installed between the two side frames 03, located below the conveyor belt 01 and near the downstream side of the conveyor belt 01. The scraping dust removal mechanism 8 is used to clean and remove dust from the lower surface of the conveyor belt 01 during its return journey. The scraping dust removal mechanism 8 includes a U-shaped cover 81 fixed between the two side frames 03, a box 82 fixed inside the U-shaped cover 81 with its opening facing upward, an airbag 83 installed on the box 82, and a flexible scraper 84 installed on the top of the airbag 83. The airbag 83 is in an inflated state, and the shape of the flexible deformable surface 831 on the top is adapted to the lower surface of the conveyor belt 01. The flexible scraper 84 is installed on the flexible deformable surface 831 and slides against the lower surface of the conveyor belt 01. A second suction pipe 812 is connected to the second guide port 811 at the bottom of the U-shaped cover 81, and the second suction pipe 812 is connected to an external vacuum cleaner.

[0080] The flexible scraper 84 is made of rubber and is detachably installed on the flexible deformable surface 831 (the specific detachable installation method uses existing technology and will not be described in detail) so that the flexible scraper 84 can be replaced when it is severely worn.

[0081] In addition, the airbag body 83 is fixed inside the box body 82, and the box body 82 and the airbag body 83 together form an air chamber 85. The bottom of the box body 82 is connected to a cylinder body 86, and a piston 87 is slidably installed inside the cylinder body 86. A vertically extending second spring 88 is fixed on the bottom wall of the inner cylinder body 86, and the top of the second spring 88 is fixed to the lower surface of the piston 87.

[0082] like Figure 12 As shown in the figure, the arrows indicate the airflow direction at each point during dust removal, and the dashed arrows indicate the running direction of the conveyor belt 01. When the conveyor belt 01 returns to the top of the scraping dust removal mechanism 8, the flexible scraper 84, supported by the expansion of the airbag 83, closely adheres to the lower surface of the conveyor belt 01. As the conveyor belt 01 moves, it scrapes the dust adhering to its surface, peeling the dust off the surface of the conveyor belt 01. The peeled dust falls into the U-shaped cover 81 and is sucked by the external vacuum cleaner through the second guide port 811 and the second suction pipe 812. The U-shaped cover 81 has openings on both sides for air intake, which eventually converges into the second guide port 811, improving the dust capture effect and preventing some dust from remaining in the U-shaped cover 81 and causing incomplete dust removal.

[0083] In addition, the dust collection hood 09 above and the first dust suction pipe 32 work together with the scraping dust removal mechanism 8 below to achieve all-round collection of dust from the conveyor belt 01 during the conveying of ore, return trip and transfer point, with significant environmental protection effect.

[0084] The flexible deformable surface 831 of the airbag body 83 adapts to slight vibrations or shape changes of the conveyor belt 01, ensuring that the flexible scraper 84 always adheres to the lower surface of the conveyor belt 01, thus avoiding adhesion and cleaning failure.

[0085] When the conveyor belt 01 presses down on the airbag 83, the airbag 83 is compressed, the volume of the air chamber 85 decreases, and the internal air, after being compressed, flows downward into the cylinder 86, pushing the piston 87 to slide downward against the elastic force of the second spring 88. The second spring 88 is compressed. When the conveyor belt 01 moves upward, the airbag 83 expands under the action of its own elasticity and the second spring 88 returning to its original position and pushing the piston 87 upward to replenish the gas. The volume of the air chamber 85 recovers, pushing the flexible scraper 84 to fit against the lower surface of the conveyor belt 01, realizing the adaptive dynamic adjustment of the flexible scraper 84.

[0086] The flexible deformation of the airbag body 83, combined with the buffer structure formed by the piston 87 and the second spring 88, allows the flexible scraper 84 to adaptively and dynamically adjust to follow the fluctuations in the shape of the conveyor belt 01, thereby ensuring that the flexible scraper 84 can continuously adhere to the lower surface of the conveyor belt 01 and ensure stable cleaning effect.

[0087] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
