Description

Technical Field

[0001] This invention relates to the field of filter element seam coating technology, and particularly to a hydraulic filter element seam coating production line. Background Technology

[0002] Filter cartridges are mainly used to separate solid particles from liquids or gases to protect the normal operation of equipment. When fluid enters a filter cartridge containing a filter screen of a certain size, impurities are blocked, while clean fluid flows out through the filter cartridge.

[0003] During the production of hydraulic filter elements, a glue-filling process is typically performed at the seams to ensure the filter element's integrity and reliability. However, in practice, the glue used at the seams is often a room-temperature curing adhesive, which has a long curing period. Furthermore, before the glue-filling process, it is difficult to effectively fix the filter media (such as filter paper or filter cloth) at the seams, posing numerous challenges to the glue-filling operation.

[0004] Chinese patent application number 202010989949.4 discloses a hydraulic glue injection tooling for the seam of a filter element, including a base; a clamping mechanism comprising multiple clamping components arranged side by side, each clamping component including a first clamping plate and a second clamping plate, the first clamping plate and the second clamping plate being parallel to each other and opposite to each other; and a linear reciprocating movement mechanism including a drive component and a slide table, the slide table being slidable relative to the base, the first clamping plate being fixed to the base, the second clamping plate being fixed to the slide table, the output end of the drive component being able to apply a driving force to the second clamping plate, the driving force forcing the second clamping plate to move parallel to and close to the first clamping plate, after the filter screen is passed around the first clamping plate and the second clamping plate, the two free ends of the filter screen are placed between the first clamping plate and the second clamping plate, and the drive component drives the second clamping plate to move closer to the first clamping plate, thereby clamping and fixing the two free ends of the filter screen, reducing the gap of its connection seam, and making its connection tighter.

[0005] Although the aforementioned patented technology achieves the clamping and fixing effect on the free end of the filter screen through the coordinated operation of the first and second clamping plates, effectively reducing the gap at the joint, in practical applications, the gap between the two free ends of the filter element has a crucial impact on the final bonding strength of the filter element.

[0006] Specifically, when the gap width between the two free ends of the filter element exceeds a reasonable range, a series of adverse consequences will occur. On the one hand, due to the excessively wide gap, the amount of adhesive required during the bonding process will increase significantly. This not only leads to an increase in material costs, but also results in an unsightly adhesive seam, affecting the overall quality of the product. On the other hand, the excessively wide gap provides ample space for adhesive flow, making it easy for the adhesive to seep into the fixture along the adhesive seam, thus causing adhesion between the filter element and the fixture.

[0007] Conversely, if the gap between the two free ends of the filter element is too small, the adhesive will have difficulty entering the joint, resulting in insufficient bonding strength at the joint and a loose seal. This joint defect increases the risk of bypass, meaning the filtered medium may bypass the filtration effect of the filter media and bypass through the loose joint, thereby reducing the filtration effect and affecting the performance of the entire filtration system.

[0008] Therefore, given the current limitations of coating the seams of filter elements, developing a hydraulic coating line for the seams of filter elements is particularly urgent and important for promoting the development of related technologies. Summary of the Invention

[0009] The purpose of this invention is to provide a hydraulic filter element seam coating production line to solve the technical problems mentioned in the background art.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A hydraulic filter element seam adhesive coating production line includes a frame and a support component mounted on the frame. The frame has upper and lower layers. The upper layer of the frame is equipped with an adhesive coating device, and the lower layer of the frame is equipped with a heat curing device.

[0012] The frame is equipped with a load-bearing downlink device and a load-bearing uplink device at both ends;

[0013] The support member is provided with a clamping part. The lower half of the clamping part is used to fix and clamp the filter element, and the upper half of the clamping part is used to adjust the width of the center slit of the filter element.

[0014] An adjustment component is provided in the lower half of the clamping part. The adjustment component is used to adjust the state changes of the lower half of the clamping part in different areas of the frame, so as to adjust the width of the filter element seam.

[0015] When the support is moved to the adhesive application station, the upper part of the clamping part widens the gap in the filter element; when the support is moved to the heat curing station, the upper part of the clamping part narrows the gap in the filter element.

[0016] Preferably, the clamping part includes:

[0017] A fixed clamping member includes a fixing block disposed on a support member, wherein a first deflecting block is hinged to the top of the fixing block;

[0018] The movable clamping member includes a sliding block disposed on a support member, the top of which is hinged to a second yaw block.

[0019] Preferably, the fixed block is fixedly connected to the support member, and the sliding block is slidably connected to the support member; an array of elastic members are provided between the fixed block and the sliding block.

[0020] Preferably, the adjusting component includes:

[0021] The jacking component is located inside the fixed block and the sliding block;

[0022] The pusher is located inside the fixed block and the sliding block and contacts the bottom of the pusher.

[0023] When the pushing member moves axially, it pushes against the jacking member, so that the jacking member pushes against the first sway block and the second sway block, and forces the first sway block and the second sway block to deflect.

[0024] Preferably, the pushing member includes:

[0025] The first movable block is located inside the fixed block and is slidably connected to the fixed block for limiting.

[0026] The second movable block is located inside the sliding block and is slidably connected to the sliding block for limiting.

[0027] The stepped groove is provided on both the first and second movable blocks, and the pushing member is in contact with the stepped groove.

[0028] Preferably, the pushing member includes a mounting groove formed on the fixed block and the sliding block, a pushing rod is provided in the mounting groove, an elastic part is provided between the pushing rod and the mounting groove, and the end of the pushing rod away from the elastic part contacts the stepped groove.

[0029] Preferably, the smooth portion of the stepped groove is provided with a groove.

[0030] Preferably, the outer side of the support member is provided with a pressure block, the pressure block is fixedly connected to the first movable block, and the pressure block is limited and slidably connected to the second movable block.

[0031] Preferably, the frame is provided with a guide member, which is used to compress the pressure block.

[0032] Preferably, the support member is provided with a pushing part, the pushing part including a crank handle rotatably connected to the support member, and a pushing block is provided at the connection end of the crank handle and the support member. When the crank handle is turned, the pushing block pushes the movable clamping member to move towards the fixed clamping member.

[0033] The technical effects and advantages of this invention are as follows:

[0034] This invention utilizes fixed and movable clamping components, along with push and push structures, and guide components to compress the pressure block, causing the swaying block to deflect and achieve a V-shaped area change. During adhesive application, the first and second swaying blocks are spaced far apart to expand the V-shaped area between them, facilitating adhesive penetration into the gaps at the free end of the filter element, avoiding application problems, ensuring adhesive quality and effectiveness, and preventing adhesive from sticking to the clamps. During curing, the first and second swaying blocks move closer together to shrink the V-shaped area between them, compressing the adhesive, reducing the adhesive gap, improving aesthetics, increasing the bonding area, reducing bypass phenomena, and also bonding excess bending parts, thus reducing the scrap rate.

[0064] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] Example 1

[0066] Reference Figures 1 to 14 As shown, the present invention provides a hydraulic filter element seam adhesive coating production line, including a frame 1, which is configured as a two-layer frame 1. The upper layer of the frame 1 is provided with an adhesive coating device 14, and the lower layer of the frame 1 is provided with a heating and curing device 13.

[0067] When applying adhesive to the center seam of the filter element, the adhesive application device 14 applies adhesive to the center seam formed by the joining of the two free ends of the filter element, and then the heating and curing device 13 heats and cures the adhesive applied to the center seam of the filter element.

[0068] It should be noted that the adhesive applied to the seam of the filter element in this application is a heat-curing adhesive. The principle of heat-curing adhesive curing by heat is existing technology and will not be elaborated further here.

[0069] Reference Figures 1 to 6 As shown, the frame 1 is provided with a carrying down device 11 and a carrying up device 12 at both ends.

[0070] The carrying downstream device 11 is used to transport the coated filter element from the upper layer to the lower layer of the frame 1.

[0071] The carrying upward device 12 is used to transport the filter element after the adhesive has been cured from the lower layer to the upper layer of the frame 1.

[0072] Reference Figures 1 to 7 As shown, a support member 2 is mounted on the frame 1; the support member 2 is provided with a clamping part, the lower half of which is used to fix and clamp the filter element, and the upper half of which is used to adjust the width of the center slit of the filter element.

[0073] The clamping part includes a fixed clamping member 3 fixedly installed on the support member 2, and a movable clamping member 4 slidably connected to the support member 2 is provided on the outside of the fixed clamping member 3.

[0074] The frame 1 is equipped with a flow channel system, and the support component 2 is located inside the flow channel. During use, the flow channel system drives the support component 2 to move on the frame 1. The design of the flow channel system is prior art and will not be described in detail here.

[0075] The fixed clamping part 3 and the movable clamping part 4 are used to fix the two free ends of the filter element to facilitate subsequent glue application.

[0076] Reference Figure 7 As shown, the support member 2 is provided with a pushing part 6. The pushing part 6 includes a crank 601 that is rotatably connected to the support member 2. The connection end of the crank 601 and the support member 2 is provided with a pushing block 602. When the crank 601 is rotated, the pushing block 602 pushes the movable clamping member 4 to move towards the fixed clamping member 3.

[0077] The push block 602 includes an eccentric cylinder, and the crank handle 601 is connected to the eccentric position of the eccentric cylinder. After the crank handle 601 is turned, the eccentric cylinder pushes against the movable clamping member 4 so that the fixed clamping member 3 and the movable clamping member 4 complete the clamping operation of the filter element.

[0078] Reference Figures 11 to 13 As shown, an elastic element 5 is provided between the fixed clamping member 3 and the movable clamping member 4; specifically, the elastic element 5 can be a spring or a rubber block.

[0079] When the filter element returns from the lower layer of the frame 1 to the upper layer of the frame 1, the rocker handle 601 is turned in the opposite direction so that the push block 602 loses its pushing force on the movable clamping member 4. At this time, under the elastic recovery capability of the elastic member 5, the movable clamping member 4 moves away from the fixed clamping member 3 to contact the clamping of the filter element.

[0080] In use, first place the two free ends of the filter element between the fixed clamping member 3 and the movable clamping member 4, and then turn the handle 601 to make the fixed clamping member 3 and the movable clamping member 4 clamp and fix the free ends of the filter element.

[0081] After being clamped, the filter element moves towards the area of ​​the adhesive applicator 14 under the action of the flow channel system. After the support 2 moves to the area below the adhesive applicator 14, the adhesive applicator 14 applies adhesive to the filter element. Applying adhesive to the center seam through the adhesive applicator 14 is prior art and will not be described in detail here.

[0082] After the adhesive application is completed, the filter element is moved to the lower layer of the frame 1 by the carrying and descending device 11, and the filter element is transported to the heating and curing device 13 by the flow channel system of the lower layer of the frame 1. The heating and curing device 13 uses a combination of oven and fan to heat the adhesive so that it can be fully cured.

[0083] After heating and curing, it is moved to the upper layer of the frame 1 via the carrying and ascending device 12.

[0084] Finally, by reversing the rotation of the pusher 6, the movable clamping member 4 and the fixed clamping member 3 release the clamping of the filter element, and the filter element can be removed from the support member 2.

[0085] It should be noted that the frame 1 in this application is equipped with a blocking cylinder, a lifting cylinder and a sensor at a specific position to ensure the smooth operation of the filter element coating process. The installation positions of these three components can be set according to actual needs.

[0086] Example 2

[0087] While the above embodiments ensure the smooth operation of the adhesive application process at the filter element seam, in practical applications, the gap between the two free ends of the filter element significantly affects the bonding strength. When the gap width exceeds a reasonable range, several adverse effects occur: an excessively wide gap significantly increases the amount of adhesive required for bonding, not only raising material costs but also resulting in an unsightly adhesive seam and affecting product quality; simultaneously, an excessively wide gap provides space for adhesive flow, easily causing adhesive to seep into the clamp, leading to adhesion between the filter element and the clamp. Conversely, an excessively narrow gap makes it difficult for adhesive to smoothly enter the joint, resulting in insufficient bonding strength at the joint, a weak joint, increased bypass risk, reduced filtration efficiency, and impact on the overall performance of the filtration system. Therefore, a technical improvement is made based on Embodiment 1, and the improved technical solution is shown below:

[0088] Reference Figures 1 to 14 As shown, the present invention also provides a hydraulic filter element seam coating production line, including a frame 1 and a support member 2 placed on the frame. The support member 2 is provided with a clamping part. The lower half of the clamping part is used to fix and clamp the filter element, and the upper half of the clamping part is used to adjust the width of the filter element seam.

[0089] An adjustment component is provided in the lower half of the clamping part. The adjustment component is used to adjust the state changes of the lower half of the clamping part in different areas of the frame so as to adjust the width of the filter element seam.

[0090] When the support 2 moves to the glue application station, the upper half of the clamping part widens the gap in the filter element; when the support 2 moves to the heat curing station, the upper half of the clamping part narrows the gap in the filter element.

[0091] Reference Figures 7 to 13 As shown, the clamping part includes a fixed clamping member 3, which includes a fixed block 301 disposed on the support member 2, and a first sway block 302 is hinged to the top of the fixed block 301.

[0092] The movable clamping member 4 includes a sliding block 401 disposed on the support member 2, and a second deflecting block 402 is hinged to the top of the sliding block 401.

[0093] The fixed block 301 is hinged to the first sway block 302 via a torsion spring, and the hinge method between the two is preferably a hinge-type hinge method.

[0094] The sliding block 401 is hinged to the second sway block 402 via a torsion spring. The hinge is preferably a hinge-type hinge.

[0095] Reference Figures 7 to 13 As shown, the adjusting component includes a pusher 7, which is disposed inside the fixed block 301 and the sliding block 401;

[0096] The pusher 8 is disposed inside the fixed block 301 and the sliding block 401 and contacts the bottom of the pusher 7;

[0097] When the pushing member 8 moves axially, it pushes against the jacking member 7, so that the jacking member 7 pushes against the first sway block 302 and the second sway block 402 and forces them to deflect.

[0098] Reference Figures 8 to 14 As shown, the pusher 8 includes a first movable block 801, which is disposed inside the fixed block 301 and is slidably connected to the fixed block 301.

[0099] The second movable block 802 is disposed inside the sliding block 401 and is slidably connected to the sliding block 401.

[0100] The stepped groove 803 is provided on both the first movable block 801 and the second movable block 802, and the pusher 7 is in contact with the stepped groove 803.

[0101] The stepped groove 803 includes three sections: A, B, and C. When the pusher 7 is in section A, the angle between the fixed block 301 and the first sway block 302 is the largest; when the pusher 7 is in section C, the angle between the fixed block 301 and the first sway block 302 is the smallest.

[0102] It should be noted that the fixed block 301 has a first limiting groove inside for the first movable block 801 to move. The length of the first limiting groove is greater than the length of the first movable block 801, and the first limiting groove is connected to the outside.

[0103] The sliding block 401 has a second limiting groove inside for the second movable block 802 to move. The length of the second limiting groove is greater than the length of the second movable block 802. The second limiting groove is connected to the outside.

[0104] Reference Figures 9 to 13 As shown, the pusher 7 includes a mounting groove formed on the fixed block 301 and the sliding block 401. A pusher rod is provided in the mounting groove. An elastic part is provided between the pusher rod and the mounting groove. The end of the pusher rod away from the elastic part contacts the stepped groove 803.

[0105] Reference Figure 9 As shown, grooves 804 are provided on the smooth part of the stepped groove 803.

[0106] The groove 804 is used to engage with the bottom of the pusher 7, like a pin, so as to realize the position positioning of the first movable block 801 and the second movable block 802 and prevent the movement distance of the first movable block 801 and the second movable block 802 from exceeding the set value.

[0107] Reference Figures 8 to 10 As shown, the outer side of the support member 2 is provided with a pressure block 9, which is fixedly connected to the first movable block 801 and is limited and slidably connected to the second movable block 802.

[0108] The pressure block 9 is provided with a limiting groove, and a limiting slider connected to the second movable block 802 is provided in the limiting groove (see details). Figure 8 (As shown).

[0109] Reference Figure 10 As shown, the frame 1 is provided with a guide 10, which is used to squeeze the pressure block 9.

[0110] The guide member 10 presses the two sides of the pressure block 9 to different degrees, so that the first movable block 801 moves inside the fixed block 301, and the second movable block 802 moves inside the sliding block 401.

[0111] When the guide 10 presses the side of the pressure block 9 away from the support 2, the first movable block 801 moves away from the connection between the fixed block 301 and the support 2.

[0112] When the guide 10 presses the pressure block 9 toward the support 2, the first movable block 801 moves toward the connection between the fixed block 301 and the support 2.

[0113] It should be noted that the guide 10 in this application is located at the top of the flow channel. Its arrangement does not obstruct the operation of the support 2 in the flow channel, but only achieves the squeezing of the pressure block 9.

[0114] In this application, the number of guide components 10 is set to three, which are located at the glue application station, the inlet of the heat curing device 13, and the outlet of the heat curing device 13, respectively.

[0115] It should be noted that the specific shape and size of the guide 10 in this application can be set by the user to meet the movement distance requirements of the pressure block 9 at different positions.

[0116] Reference Figures 11 to 13 As shown, the fixed block 301 is fixedly connected to the support member 2, and the sliding block 401 is limited to the sliding connection with the support member 2; an array of elastic members 5 are provided between the fixed block 301 and the sliding block 401.

[0117] Reference Figure 14 As shown, the filter element has multiple triangular bending areas. One side of the triangular bending area is designated as area S1, and the other side is designated as area S2. When the filter element is not coated with adhesive in the middle seam, the two free ends are in a separated state.

[0118] In the initial state, the pusher 7 is located in region B of the stepped groove 803. At this time, the opposite sides of the first deflector block 302 and the second deflector block 402 form a V-shape (see details). Figure 9 and Figure 11 (As shown).

[0119] During operation, the operator places the two free ends of the filter element into the space defined by the fixed clamping member 3 and the movable clamping member 4. Given that the first deflecting block 302 and the second deflecting block 402 are in a V-shape at this point, this configuration allows the two free ends of the filter element to enter the gap between the fixed block 301 and the sliding block 401 more smoothly. This design effectively avoids the problem of excessive obstruction encountered by the two free ends of the filter element when entering the clamping mechanism due to an insufficient gap between the fixed block 301 and the sliding block 401.

[0120] After the filter element is installed, rotate the pushing part 6 to push against the sliding block 401, so that the fixing block 301 and the sliding block 401 clamp and fix the two free ends of the filter element, so that the bottoms of the two free ends of the filter element are in contact, preventing the filter element from falling off the clamping parts in subsequent processes.

[0121] After clamping the free end of the filter element, the flow channel system configured on the frame 1 drives the support 2 to move towards the working area where the adhesive applicator 14 is located. During this movement, the guide 10 pre-set on the frame 1 applies a compressive force to the side of the pressure block 9 facing the support 2. This force causes the pressure block 9 to move the first movable block 801 and the second movable block 802 towards the connection between the fixed block 301 and the support 2 (to... Figure 9 For example, at this time, the first active block 801 should be shifted from right to left.

[0122] As the first movable block 801 and the second movable block 802 move, the jacking member 7, originally located in region B of the stepped groove 803, gradually migrates towards region C. Since region C of the stepped groove 803 is lower than region B, under the action of the elastic potential energy of the elastic part, the end of the jacking member 7 that contacts the stepped groove 803 gradually displaces downward. Simultaneously, the pushing force exerted by the other end of the jacking member 7 on the sway block also gradually weakens.

[0123] In this situation, under the action of the elastic restoring force of the torsion spring, the first deflector block 302 deflects towards the direction of the fixed block 301, while the second deflector block 402 deflects towards the direction of the sliding block 401. During the deflection process of the first deflector block 302 and the second deflector block 402, their opposing sides continuously exert a pushing force on the S1 region of the filter element. This pushing force causes the V-shaped region between the first deflector block 302 and the second deflector block 402 to gradually expand (specifically as follows). Figure 12 (As shown).

[0124] When the adhesive applicator 14 applies adhesive to the gap between the two free ends of the filter element, the expansion of the V-shaped area facilitates smoother penetration of the adhesive into the gap. This effectively avoids adhesive application problems caused by slight deviations in the position of the support 2, such as the adhesive failing to enter the gap or not entering completely, thus ensuring the quality and effectiveness of the adhesive application. Simultaneously, because the fixing block 301 and the sliding block 401 fix the bottom of the two free ends of the filter element, the expansion of the V-shaped area prevents the adhesive from seeping through the gap and sticking to the clamp.

[0125] After the adhesive application is completed, the flow channel system transfers the support component 2 to the carrying descending device 11, which then transfers it to the lower layer of the frame 1. The flow channel system on the lower layer of the frame 1 transports the support component 2 to the heat curing device 13. During this process, the guide component 10, which is pre-installed at the inlet of the heat curing device 13, applies a compressive force to the side of the pressure block 9 away from the support component 2. This compressive force causes the pressure block 9 to move the first movable block 801 and the second movable block 802 away from the connection between the fixed block 301 and the support component 2 (to...). Figure 9 For example, at this time, the first active block 801 should be shifted from left to right.

[0126] As the first movable block 801 and the second movable block 802 move, the jacking member 7, located in region C of the stepped groove 803, gradually migrates towards region A. Since region A of the stepped groove 803 is higher than region C, the end of the jacking member 7 that contacts the stepped groove 803 gradually experiences upward displacement. Simultaneously, the jacking force applied to the sway block by the other end of the jacking member 7 also gradually increases.

[0127] As the pusher 7 pushes against the deflecting blocks, the first deflecting block 302 gradually deflects towards the second deflecting block 402, and the second deflecting block 402 also gradually deflects towards the first deflecting block 302. During the deflection process of the first deflecting block 302 and the second deflecting block 402, their opposing sides continuously exert a pushing force on the S2 region of the filter element. This pushing force causes the V-shaped region between the first deflecting block 302 and the second deflecting block 402 to gradually shrink.

[0128] The reduction in the V-shaped area compresses the adhesive that was originally located in the slit. This compression causes the adhesive level within the slit to gradually rise, reducing the final adhesive gap and improving the aesthetics of the finished filter cartridge. Furthermore, the reduced V-shaped area significantly increases the depth of the adhesive within the slit, thus increasing the bonding area between the two free ends of the filter cartridge and reducing bypass phenomena (specifically as follows...). Figure 13 (As shown).

[0129] Meanwhile, when excess bent portions enter between the fixed clamp 3 and the movable clamp 4, as the V-shaped area shrinks, some adhesive will enter above the bent portions, so that multiple bent portions can form an adhesive, reducing the scrap rate.

[0130] It should be noted that when the adhesive applicator 14 of this application applies adhesive to the middle seam of the filter element, the areas at both ends of the filter element do not need to be coated with adhesive, so as to avoid the adhesive from flowing out from both ends of the middle seam when the adhesive is squeezed. Furthermore, the subsequent process requires adhesive to be applied to both ends of the filter element for sealing. In other words, it is not necessary to apply adhesive to the areas at both ends of the filter element at this time.

[0131] After the heat curing process is completed, the flow channel system transfers the support component 2 to the carrying upward device 12, which then transfers it to the upper layer of the frame 1. As the support component 2 flows out of the heat curing device 13, the guide component 10, pre-installed at the outlet of the heat curing device 13, applies a compressive force to the pressure block 9 on the side facing the support component 2. This force causes the pressure block 9 to move the first movable block 801 and the second movable block 802 towards the connection between the fixed block 301 and the support component 2 (to...). Figure 9 For example, at this time, the first active block 801 should be shifted from right to left.

[0132] As the first movable block 801 and the second movable block 802 move, the jacking member 7, located in region A of the stepped groove 803, gradually migrates towards region B. Since region B of the stepped groove 803 is lower than region A, under the action of the elastic potential energy of the elastic part, the end of the jacking member 7 that contacts the stepped groove 803 gradually displaces downward. Simultaneously, the resisting force exerted by the other end of the jacking member 7 on the sway block also gradually weakens.

[0133] In this situation, under the action of the elastic restoring force of the torsion spring, the first deflector block 302 deflects in the direction of the fixed block 301, while the second deflector block 402 deflects in the direction of the sliding block 401. During the deflection process of the first deflector block 302 and the second deflector block 402, their opposing sides gradually form a V-shaped area to facilitate the subsequent placement of the filter element to be coated with adhesive.

[0134] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
