Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile conveying, and in particular to a conveying device and a conveying method for aluminum profile production. Background Art

[0002] In the production of aluminum profiles, the long aluminum profiles are usually placed on a conveying device composed of several rollers for transportation, so as to transport the aluminum profiles to other locations for processing;

[0003] According to a Chinese patent with application publication number CN111806955A, a transfer device for aluminum profile production is disclosed. When the aluminum profile is transferred, the aluminum profiles can be neatly transported when they are equidistantly arranged on the conveying roller, and the spacing between the first limit plate and the second limit plate is adjusted according to the actual width of the aluminum profile arrangement, so as to better meet the actual transfer work requirements of the aluminum profile. The anti-skid protrusions arranged at the middle side of the conveying roller prevent the aluminum profile from sliding during the transfer and conveying process, thereby causing the transfer and conveying phenomenon of the aluminum profile, thereby ensuring the normal transfer and conveying of the aluminum profile, ensuring work efficiency, and improving work economic benefits. However, when the device transports the aluminum profile from a low point to a high point, it is necessary to tilt the device, especially when the height difference between the upper and lower parts is large, it is necessary to set the device at a larger inclination angle. In this case, it is difficult to overcome the slipping problem of the aluminum profile by relying solely on the friction between the anti-skid protrusions and the aluminum profile.

[0012] As a preferred solution of the present invention, the front and rear parts of one side of the conveying pallet close to the positioning seat are penetrated by two straight grooves distributed on the left and right, and the bottom corners of the positioning seat are provided with bolt holes, and the positions of the bolt holes correspond to the positions of the straight grooves, and the interiors of the straight grooves and the bolt holes are jointly penetrated by studs, and the bottom of the studs is fixedly installed with a bottom cap, and the top of the bottom cap contacts the bottom of the conveying pallet, and the outer periphery of the studs is threadedly connected with a butterfly bolt, and the bottom of the butterfly bolt abuts against the top of the positioning seat.

[0013] As a preferred solution of the present invention, a dust cover is fixedly installed on the top of the rack outer frame, and the dust cover is located at the periphery of the opening of the square notch.

[0014] A conveying method of a conveying device for aluminum profile production, comprising the following steps:

[0015] S1. One of the conveying shafts is driven by a motor to rotate clockwise, and the conveying chain is further rotated with the cooperation of the left and right conveying shafts and the left and right conveying sprockets. The conveying chain rotates and drives the conveying pallet to move to the right through the mounting plate. The aluminum profile is placed on the top of the conveying pallet at the left end of the device and is transported by the conveying pallet moving to the right;

[0016] S2. The movement of the conveying pallet drives the two positioning seats to move together, thereby causing the two telescopic columns to move to the right together with the positioning blocks. At the same time, the movement of the positioning seat drives the spur rack and the counterweight component to move to the right together through the connection effect of the rack outer frame. Initially, the bottom of the counterweight ring of the counterweight component contacts the top of the guide plate at the left end, and as the counterweight component gradually moves to the right, the counterweight ring moves to the right along the top inclined surface of the guide plate at the left end. During this period, the gravity of the counterweight ring pulls the spur rack downward, and the downward movement of the spur rack drives the spur gear meshing with it to rotate. The rotation of the spur gear further drives the rotation of the lead screw, and the rotation of the lead screw produces a thread thrust effect with the inner thread hole, which then causes the telescopic column to slide from the inside of the telescopic slot to the outside. The telescopic column then drives the positioning block to move together. As the front and rear positioning blocks move, the front and rear directions of the aluminum profile are clamped.

[0017] S3. When the bottom of the counterweight ring contacts the left end of the top of the guide plate on the right end, as the counterweight ring continues to move to the right, the bottom of the counterweight ring gradually moves upward due to the thrust of the top of the guide plate on the right end. The counterweight ring moves upward, driving the spur rack upward through the counterweight rod. The upward movement of the spur rack drives the spur gear to rotate. The rotation of the spur gear drives the screw rod to rotate along the inside of the inner thread hole, so that the telescopic column drives the positioning block to move toward the telescopic slot, thereby releasing the clamping of the aluminum profile.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, the aluminum profile is conveyed to the right by the conveying component, and the gravity of the counterweight component pulls the spur rack downward. The downward movement of the spur rack drives the spur gear meshing therewith to rotate. The rotation of the spur gear further drives the screw rod to rotate. The rotation of the screw rod produces a thread thrust effect with the inner thread hole, and then the telescopic column slides along the inside of the telescopic groove to the outside. The telescopic column then drives the positioning block to move together. Since the front and rear positioning blocks move, the aluminum profile is clamped in the front and rear directions. Therefore, when there is a height difference in transportation, the aluminum profile will not slip, and the transportation effect is better.

[0020] 2. In the present invention, when the bottom of the counterweight ring contacts the left end of the top of the guide plate at the right end, as the counterweight ring continues to move to the right, the bottom of the counterweight ring gradually moves upward due to the thrust of the top of the guide plate at the right end. The counterweight ring moves upward and drives the spur rack upward through the counterweight rod. The upward movement of the spur rack drives the spur gear to rotate. The rotation of the spur gear drives the screw rod to rotate along the inside of the inner thread hole, so that the telescopic column drives the positioning block to move in the direction close to the telescopic slot, thereby releasing the clamping of the aluminum profile, facilitating the separation of the aluminum profile from the device, and thus facilitating movement to the next process.

[0021] 3. In the present invention, the overall weight of the counterweight component is increased by increasing the number of counterweight rings. As the overall weight of the counterweight component increases, that is, the downward pulling force on the spur rack increases, the torsional force of the spur rack on the spur gear increases, which in turn causes the torsional force of the spur gear on the lead screw to increase. Therefore, the spiral thrust between the lead screw and the inner thread hole increases, resulting in an increase in the clamping force of the front and rear positioning blocks on the aluminum profile, that is, the friction between the positioning blocks and the aluminum profile becomes larger, thereby overcoming the slippage problem of the heavier aluminum profile.

[0022] 4. In the present invention, the pull ring is pulled up to drive the insertion rod and the spring fixing block to slide upward, so that the bottom of the insertion rod is separated from the anti-slip groove, and the counterweight ring can be removed from the outer wall of the counterweight rod. The disassembly is convenient, and the overall weight of the counterweight component is reduced, thereby reducing the load of the conveying component during operation, which is beneficial to saving electricity and reducing the cost of use.

[0023] 5. In the present invention, the locking effect between the positioning seat and the conveying support plate is released by loosening the butterfly bolt, and then the positioning seat is slid forward and backward to adjust the distance between the front and rear positioning seats. The distance adjustment between the front and rear positioning seats is to adjust the distance between the front and rear positioning blocks. When the distance between the front and rear positioning blocks is adjusted to be slightly larger than the front and rear width of the aluminum profile, each butterfly bolt is tightened to lock the positioning seat and the conveying support plate to prevent the positioning seat from moving again, thereby meeting the transportation of aluminum profiles of different widths and improving the transportation range of the device.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 9 The technical solution provided by the present invention specifically includes the following embodiments:

[0037] The conveying component 200 includes two conveying shafts 201 rotatably mounted at both ends of the two side panels 100, and two conveying sprockets 202 distributed front and back are fixedly mounted on the outer walls of the conveying shafts 201. A conveying chain 203 is commonly sleeved on the outer peripheries of the two conveying sprockets 202 in the left and right directions. There are two conveying chains 203, and a plurality of mounting pieces 204 distributed at equal distances are fixedly mounted on one side of the two conveying chains 203 that are close to each other, wherein a conveying support plate 205 is fixedly mounted on the top of the two mounting pieces 204 in the front and back positions, and two positioning seats 208 distributed front and back symmetrically are slidably provided on the top of the conveying support plate 205, and the two positioning seats 208 are mutually symmetrically ... A telescopic groove 209 is provided on the side close to each other, and a telescopic column 2010 is slidably installed inside the telescopic groove 209. A positioning block 2011 is fixedly installed on the end close to the two telescopic columns 2010. An inner thread hole 2012 is provided on the side far away from the two telescopic columns 2010. A screw rod 2013 is connected to the inner thread of the inner thread hole 2012. The outer wall of the screw rod 2013 is rotatably connected to the side wall of one end of the positioning seat 208. A spur gear 2014 is fixedly installed on the end of the screw rod 2013. A spur rack 2015 is meshed with the periphery of the spur gear 2014. The counterweight component 300 is fixedly installed on the bottom side of the spur rack 2015.

[0038] A rack outer frame 2016 is fixedly installed on one side of the positioning seat 208 away from the telescopic column 2010, the outer wall of the spur rack 2015 is slidably connected to the inner wall of one side of the rack outer frame 2016, the spur gear 2014 is located inside the rack outer frame 2016, and a square notch 2017 is opened through the top of the rack outer frame 2016, and the specifications of the square notch 2017 are larger than those of the spur rack 2015.

[0039] Specifically, the present embodiment drives one of the conveying shafts 201 to rotate clockwise through an externally arranged motor. The motor in the present device drives the conveying shaft 201 to rotate by existing methods such as belt drive, chain drive, and direct coupling connection. Further, with the cooperation of the left and right conveying shafts 201 and the left and right conveying sprockets 202, the conveying chain 203 is rotated. The rotation of the conveying chain 203 drives the conveying pallet 205 to move to the right through the mounting plate 204. The aluminum profile is placed on the top of the conveying pallet 205 at the left end of the device and is transported by the conveying pallet 205 moving to the right. The movement of the conveying pallet 205 drives the two positioning seats 208 to move together, thereby causing the two telescopic columns 2010 to move to the right together with the positioning block 2011. At the same time, the positioning seats The movement of 208 drives the spur rack 2015 and the counterweight component 300 to move to the right together through the connection action of the rack outer frame 2016. The gravity of the counterweight component 300 pulls the spur rack 2015 downward. The downward movement of the spur rack 2015 drives the spur gear 2014 meshing therewith to rotate. The rotation of the spur gear 2014 further drives the screw rod 2013 to rotate. The rotation of the screw rod 2013 produces a thread thrust effect with the inner thread hole 2012, and then makes the telescopic column 2010 slide along the inside of the telescopic slot 209 to the outside. The telescopic column 2010 then drives the positioning block 2011 to move together. Due to the movement of the front and rear positioning blocks 2011, the front and rear directions of the aluminum profile are clamped. When there is a height difference during transportation, the aluminum profile will not slip.

[0040] Furthermore, a clearance groove 207 is provided through one side of the conveying pallet 205 near the positioning seat 208, and the width of the clearance groove 207 is greater than the width of the spur rack 2015. The spur rack 2015 movably passes through the clearance groove 207; by providing the clearance groove 207, the spur rack 2015 can make way, and at the same time, because the width of the clearance groove 207 is greater than the width of the spur rack 2015, the spur rack 2015 will not interfere with the conveying pallet 205 when moving forward and backward, thereby ensuring that the spur rack 2015 can move smoothly forward and backward.

[0041] Furthermore, a dust cover 700 is fixedly installed on the top of the rack outer frame 2016, and the dust cover 700 is located outside the opening of the square notch 2017; by installing the dust cover 700 to protect the spur rack 2015, the service life of the spur rack 2015 is improved.

[0042] Embodiment 2: The counterweight component 300 includes a counterweight rod 301 fixedly mounted on one side of the bottom of the spur rack 2015, the outer wall of the counterweight rod 301 is provided with a plurality of equally spaced anti-skid grooves 302, the outer periphery of the counterweight rod 301 is provided with a counterweight ring 303, the outer wall of the counterweight ring 303 is provided with a primary circular groove 304, the inner wall of the counterweight ring 303 is provided with a secondary circular groove 306, the secondary circular groove 306 is connected to the primary circular groove 304, and the secondary circular groove 306 is concentric with the primary circular groove 304, and the inner diameter of the secondary circular groove 306 is smaller than the inner diameter of the primary circular groove 304. The secondary circular groove 306 has an insert rod 305 slidably installed inside, a pull ring 309 is fixedly installed on the top of the insert rod 305, the bottom of the insert rod 305 is inserted into the anti-slip groove 302, a spring fixing block 307 is fixedly installed on the outer wall of the insert rod 305, the outer wall of the spring fixing block 307 is slidably connected with the inner wall of the primary circular groove 304, and a reset spring 308 is sleeved on the periphery of the insert rod 305, the reset spring 308 is located inside the primary circular groove 304, and the reset spring 308 is fixedly installed between the bottom of the spring fixing block 307 and the bottom wall of the primary circular groove 304;

[0043] Two guide plates 400 distributed left and right are fixedly installed between the two side panels 100, and two fixed longitudinal tubes 500 distributed left and right are fixedly installed between the two side panels 100. The guide plates 400 are fixedly installed on the outer walls of the fixed longitudinal tubes 500, and the left and right guide plates 400 are symmetrically distributed about the central axis of the side panels 100.

[0044] Specifically, the counterweight rod 301 is driven to move rightward by the spur rack 2015, and the counterweight rod 301 drives the counterweight ring 303 to move together. Initially, the bottom of the counterweight ring 303 contacts the top of the guide plate 400 at the left end, and as the counterweight ring 303 gradually moves to the right, the counterweight ring 303 moves to the right along the top inclined surface of the guide plate 400 at the left end. During this period, the gravity of the counterweight ring 303 pulls the spur rack 2015 downward, and the downward movement of the spur rack 2015 drives the spur gear 2014 meshing with it to rotate. The rotation of the spur gear 2014 further drives the screw rod 2013 to rotate. The rotation of the screw rod 2013 produces a threaded thrust effect with the inner thread hole 2012, and then the telescopic column 2010 slides from the inside of the telescopic slot 209 to the outside. The telescopic column 2010 then drives the positioning block 211 to move together. The positioning block 2011 moves to clamp the aluminum profile in the front and rear directions. When there is a height difference during transportation, the aluminum profile will not slip. When the bottom of the counterweight ring 303 contacts the left end of the top of the guide plate 400 at the right end, as the counterweight ring 303 continues to move to the right, the bottom of the counterweight ring 303 is thrust by the top of the right end guide plate 400 and gradually moves upward. The counterweight ring 303 moves upward and drives the spur rack 2015 to move upward through the counterweight rod 301. The spur rack 2015 moves upward and drives the spur gear 2014 to rotate. The rotation of the spur gear 2014 drives the screw rod 2013 to rotate along the inside of the inner thread hole 2012, so that the telescopic column 2010 drives the positioning block 2011 to move toward the telescopic slot 209, thereby releasing the clamping of the aluminum profile and facilitating the separation of the aluminum profile from the device, thereby facilitating movement to the next process.

[0045] It should be noted that when conveying some heavier aluminum profiles, if it is necessary to convey them up and down, the inclined aluminum profiles are easy to slide to the left between the front and rear positioning blocks 2011 during the conveying process. At this time, the overall weight of the counterweight component 300 can be increased by increasing the number of counterweight rings 303. Since the overall weight of the counterweight component 300 increases, that is, the downward pulling force on the spur rack 2015 increases, the torsional force of the spur rack 2015 on the spur gear 2014 increases, which in turn causes the torsional force of the spur gear 2014 on the screw rod 2013 to increase. Therefore, the spiral thrust between the screw rod 2013 and the inner thread hole 2012 increases, causing the front and rear positioning blocks 2011 to press the aluminum profiles to the left. The clamping force of the profile is increased, that is, the friction between the positioning block 2011 and the aluminum profile becomes larger, thereby overcoming the problem of aluminum profile slipping. In addition, the counterweight ring 303 and the counterweight rod 301 in the device are connected by the insertion rod 305 and the anti-slip groove 302, which is extremely convenient to install. When transporting light aluminum profiles, the insertion rod 305 and the spring fixing block 307 can be driven to slide upward by pulling the pull ring 309, so that the bottom of the insertion rod 305 is disengaged from the anti-slip groove 302, and the counterweight ring 303 can be removed from the outer wall of the counterweight rod 301. The disassembly is convenient, reducing the overall weight of the counterweight component 300, thereby reducing the load on the operation of the conveying component 200, which is beneficial to saving electricity and reducing the cost of use.

[0046] Embodiment 3: The front and rear parts of one side of the conveying pallet 205 close to the positioning seat 208 are penetrated by two straight grooves 206 distributed on the left and right, and the bottom corners of the positioning seat 208 are provided with bolt holes 2008, and the positions of the bolt holes 2008 correspond to the positions of the straight grooves 206. The interiors of the straight grooves 206 and the bolt holes 2008 are jointly penetrated by studs 600, and the bottom of the studs 600 is fixedly installed with a bottom cap 601, and the top of the bottom cap 601 is in contact with the bottom of the conveying pallet 205, and the outer periphery of the studs 600 is threadedly connected with butterfly bolts 602, and the bottom of the butterfly bolts 602 is in contact with the top of the positioning seat 208.

[0047] Specifically, in this embodiment, when it is necessary to convey aluminum profiles with different front and rear widths, it is necessary to adjust the distance between the two front and rear positioning seats 208. Specifically, the butterfly bolt 602 can be loosened to release the locking effect between the positioning seat 208 and the conveying pallet 205, and then the positioning seat 208 is slid forward and backward to adjust the distance between the front and rear positioning seats 208. The distance adjustment between the front and rear positioning seats 208 is to adjust the distance between the front and rear positioning blocks 2011. After the distance between the front and rear positioning blocks 2011 is adjusted to be slightly larger than the front and rear width of the aluminum profile, each butterfly bolt 602 is tightened to lock the positioning seat 208 with the conveying pallet 205 to prevent the positioning seat 208 from moving again, thereby meeting the transportation of aluminum profiles of different widths and improving the conveying range of the present device.

[0048] A conveying method of a conveying device for aluminum profile production, comprising the following steps:

[0049] S1. One of the conveying shafts 201 is driven by a motor to rotate clockwise, and the conveying chain 203 is further rotated with the cooperation of the left and right conveying shafts 201 and the left and right conveying sprockets 202. The conveying chain 203 rotates and drives the conveying pallet 205 to move to the right through the mounting plate 204. The aluminum profile is placed on the top of the conveying pallet 205 at the left end of the device and is transported by the conveying pallet 205 moving to the right;

[0050] S2, the movement of the conveying pallet 205 drives the two positioning seats 208 to move together, thereby making the two telescopic columns 2010 together with the positioning block 2011 move to the right, and at the same time, the movement of the positioning seat 208 drives the spur rack 2015 and the counterweight component 300 to move to the right together through the connection effect of the rack outer frame 2016. At first, the bottom of the counterweight ring 303 of the counterweight component 300 contacts the top of the left guide plate 400, and as the counterweight component 300 gradually moves to the right, the counterweight ring 303 moves to the right along the top inclined surface of the left guide plate 400. The gravity of the heavy ring 303 pulls the spur rack 2015 downward, and the spur rack 2015 moves downward to drive the spur gear 2014 meshing therewith to rotate. The rotation of the spur gear 2014 further drives the screw rod 2013 to rotate. The rotation of the screw rod 2013 produces a thread thrust effect with the inner thread hole 2012, and then the telescopic column 2010 slides from the inside of the telescopic slot 209 to the outside. The telescopic column 2010 then drives the positioning block 2011 to move together. As the front and rear positioning blocks 2011 move, the aluminum profile is clamped in the front and rear directions.

[0051] S3. When the bottom of the counterweight ring 303 contacts the left end of the top of the guide plate 400 at the right end, as the counterweight ring 303 continues to move to the right, the bottom of the counterweight ring 303 gradually moves upward due to the thrust of the top of the guide plate 400 at the right end. The counterweight ring 303 moves upward and drives the spur rack 2015 to move upward through the counterweight rod 301. The spur rack 2015 moves upward and drives the spur gear 2014 to rotate. The rotation of the spur gear 2014 drives the screw rod 2013 to rotate along the inside of the inner thread hole 2012, so that the telescopic column 2010 drives the positioning block 2011 to move toward the direction close to the telescopic slot 209, thereby releasing the clamping of the aluminum profile.

[0052] In the present scheme, when a conveying device for aluminum profile production is working, one of the conveying shafts 201 is driven to rotate clockwise by an externally arranged motor, and further, with the cooperation of the left and right conveying shafts 201 and the left and right conveying sprockets 202, the conveying chain 203 is rotated, and the conveying chain 203 rotates and drives the conveying pallet 205 to move to the right through the mounting plate 204. The aluminum profile is placed on the top of the conveying pallet 205 at the left end of the device and is transported by the conveying pallet 205 moving to the right. The movement of the conveying pallet 205 drives the two positioning seats 208 to move together, and then the two telescopic columns 2010 together with the positioning block 2011 move to the right. At the same time, the movement of the positioning seat 208 drives the spur rack 2015 and the counterweight component 300 to move to the right together through the connection effect of the rack outer frame 2016. Initially, the counterweight component 300 is The bottom of the weight ring 303 contacts the top of the guide plate 400 at the left end, and as the counterweight component 300 gradually moves to the right, the counterweight ring 303 moves to the right along the top inclined surface of the guide plate 400 at the left end. During this period, the gravity of the counterweight ring 303 pulls the spur rack 2015 downward, and the spur rack 2015 moves downward to drive the spur gear 2014 meshing with it to rotate. The rotation of the spur gear 2014 further drives the screw rod 2013 to rotate. The rotation of the screw rod 2013 produces a thread thrust effect with the inner thread hole 2012, and then the telescopic column 2010 slides from the inside of the telescopic slot 209 to the outside. The telescopic column 2010 then drives the positioning block 2011 to move together. As the front and rear positioning blocks 2011 move, the aluminum profile is clamped in the front and rear directions. When there is a height difference during transportation, the aluminum profile will not slip.

[0053] When the bottom of the counterweight ring 303 contacts the left end of the top of the guide plate 400 at the right end, as the counterweight ring 303 continues to move to the right, the bottom of the counterweight ring 303 is gradually moved upward by the thrust of the top of the right guide plate 400, and the counterweight ring 303 moves upward through the counterweight rod 301 to drive the spur rack 2015 to move upward, and the spur rack 2015 moves upward to drive the spur gear 2014 to rotate, and the rotation of the spur gear 2014 drives the screw rod 2013 to rotate along the inside of the inner thread hole 2012, so that the telescopic column 2010 drives the positioning block 2011 to move in the direction close to the telescopic slot 209, thereby releasing the clamping of the aluminum profile, making it convenient for the aluminum profile to be separated from the device, so as to facilitate movement to the next process;

[0054] In the present device, when it is necessary to transport aluminum profiles with different front and rear widths, it is necessary to adjust the distance between the two front and rear positioning seats 208. Specifically, the butterfly bolts 602 can be loosened to release the locking effect between the positioning seat 208 and the conveying support plate 205, and then the positioning seat 208 is slid forward and backward to adjust the distance between the front and rear positioning seats 208. The distance adjustment between the front and rear positioning seats 208 is to adjust the distance between the front and rear positioning blocks 2011. After the distance between the front and rear positioning blocks 2011 is adjusted to be slightly larger than the front and rear width of the aluminum profile, each butterfly bolt 602 is tightened to lock the positioning seat 208 with the conveying support plate 205 to prevent the positioning seat 208 from moving again, thereby meeting the transportation of aluminum profiles of different widths and improving the transportation range of the present device.

[0055] When conveying some heavier aluminum profiles, if it is necessary to convey them up and down, the inclined aluminum profiles are easy to slide to the left between the front and rear positioning blocks 2011 during the conveying process. At this time, the overall weight of the counterweight component 300 can be increased by increasing the number of counterweight rings 303. Since the overall weight of the counterweight component 300 increases, that is, the downward pulling force on the spur rack 2015 increases, the torsional force of the spur rack 2015 on the spur gear 2014 increases, which in turn causes the torsional force of the spur gear 2014 on the screw rod 2013 to increase. Therefore, the spiral thrust between the screw rod 2013 and the inner thread hole 2012 increases, causing the front and rear positioning blocks 2011 to clamp the aluminum profile. The force increases, that is, the friction between the positioning block 2011 and the aluminum profile becomes larger, thereby overcoming the problem of aluminum profile slipping. In addition, the counterweight ring 303 and the counterweight rod 301 in the device are connected by the insertion rod 305 and the anti-skid groove 302, which is extremely convenient to install. When transporting light aluminum profiles, the insertion rod 305 and the spring fixing block 307 can be driven to slide upward by pulling the pull ring 309, so that the bottom of the insertion rod 305 is separated from the anti-skid groove 302, and the counterweight ring 303 can be removed from the outer wall of the counterweight rod 301. The disassembly is convenient, which reduces the overall weight of the counterweight component 300, thereby reducing the load on the operation of the conveying component 200, which is beneficial to saving electricity and reducing the cost of use.

[0056] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
