Definitions
- the present invention relates to a meandering straightening device for non-contact type conveyance of a belt-shaped base material in which a belt-shaped base material that continuously runs is floated by one or more floater groups and is conveyed in a state of non-contact with a transfer roll.
- roll transport is generally used for transporting the strip-shaped substrate while contacting and supporting the strip-shaped substrate.
- the conventional roll transfer method has a problem that defects such as scratches and peeling are likely to occur on the surface of the base material and the coated coating film due to the contact between the belt-shaped base material and the transfer roll. Therefore, as one of the methods to solve this problem, a non-contact transfer device was developed to transfer the band-shaped base material in a non-contact state with the transfer roll by using a floater that floats the band-shaped base material by the pressure of gas. Has been done.
- the belt-shaped base material floats, and the frictional force due to contact with the support does not work, so the belt-shaped base material slides sideways to cause meandering, or the belt-shaped base material is moved. It has been pointed out that there is a problem in strip passing stability, such as the strip-shaped base material flapping due to the airflow or the like jetted to float. Therefore, many studies have been made to prevent the meandering and fluttering of the floated strip-shaped substrate and to stably convey the strip-shaped substrate.

- a side plate whose height is higher than the normal level of conveyance of the strip-shaped substrate, it is possible to convey the strip-shaped substrate without any contact between the widthwise ends of the strip-shaped substrate.
- the floater of Patent Document 1 increases the height of only the outermost side plate in the width direction of the base material, the floater for returning the base material to the center unless the belt-shaped base material causes a large meandering.
- the driving force does not work. Therefore, when the meandering amount of the base material is relatively small, it is difficult to accurately convey the strip-shaped base material in the center in the width direction.
- Patent Document 2 As a method for correcting the shearing force applied to the strip-shaped substrate, in Patent Document 2, a gas jet nozzle that blows high-pressure gas from above or below the edge portion of the strip-shaped substrate is arranged above the floater to form a strip-shaped substrate. A method of operating the inclination of a material is disclosed.

- a meandering straightening device for a strip-shaped base material which can correct the meandering of the strip-shaped base material and stably convey it even if the generated meandering amount is small, without adversely affecting the surface of the strip-shaped base material. Especially.
- the inventors have made extensive studies to solve the above problems.
- the most upstream floater of the floater group and the conveyance roll immediately upstream of the floater are adjacent to each other.
- the widthwise height of the strip-shaped substrate is forcibly changed in any one or more sections between the two floaters and between the most downstream floater of the floater group and the transport roll immediately downstream of the floater. It was found that the inclination can be controlled with high precision even with a small amount of meandering, and the present invention has been developed.
- the present invention relates to the meandering straightening device in the non-contact type conveyance of a belt-shaped base material which floats, supports and conveys the belt-shaped base material continuously traveling by one or more floater groups arranged in series, Between the most upstream floater of the floater group and the transport roll immediately upstream of the floater, between two adjacent floaters, and the most downstream floater of the floater group and the transport roll immediately downstream of the floater.
- a gas nozzle that blows gas is installed below the strip-shaped base material as a mechanism for imparting an inclination to the strip-shaped base material and operating the inclination in the width direction of the strip-shaped base material on the floater in any one or more sections between
- a meandering straightening device for non-contact type conveyance of a strip-shaped substrate is provided.
- the gas nozzle in the meandering straightening device for the strip-shaped substrate of the present invention is characterized in that the center distance between the most upstream floater of the floater group and the transport roll immediately upstream of the floater, the center distance between two adjacent floaters.
- the center-to-center distance between the most downstream floater of the floater group and the transport roll immediately downstream of the floater is S, it is preferably installed within S / 2 of the floater.
- the gas nozzle when the average flying height of the strip-shaped substrate on the floater is H, the gas nozzle lowers by H or more based on the height of the strip-shaped substrate before gas injection. It is preferably installed.
- the pressure of the gas injected from the gas nozzle is preferably adjusted in proportion to the total tension of the strip-shaped substrate.
- a belt-shaped substrate is continuously floated by a floater and is conveyed in a non-contact state with a conveyance roll. Gas is injected from the gas nozzle installed below the material to forcibly incline the strip-shaped base material to correct the meandering of the strip-shaped base material. It can be returned to the center position, and the belt-shaped substrate can be stably transported.
- FIG. 6 is a cross-sectional view of the floater 2 used for non-contact conveyance of the strip-shaped substrate 1, taken along line A-A ′. It is a figure explaining the meandering correction principle in the floater 2 of a prior art. It is a figure explaining the meandering straightening device 20 using the gas nozzle 7 concerning one embodiment of the present invention. It is a figure explaining installation distance K and nozzle distance L of gas nozzle 7 concerning one embodiment of the present invention, and average flying height H of beltlike substrate 1.
- FIG. 1 shows, as an example, a side view of a floater 2 which can be used in the present invention and which floats and conveys a continuously running strip-shaped substrate 1.
- the floater 2 is intended to float and convey the strip-shaped substrate 1 by injecting gas from below the strip-shaped substrate 1 toward the lower surface of the strip-shaped substrate 1.
- a floater 2 is installed below the running strip-shaped substrate 1, and the inside of the floater 2 is supplied with gas from a fan, a blower, or the like (not shown), so that the atmospheric pressure is higher than the atmospheric pressure. The pressure is high.
- the high-pressure gas inside the floater 2 is jetted toward the lower surface of the strip-shaped substrate from a slit-shaped gas jet port (slit nozzle) 5 provided in the strip-shaped substrate width direction 11 on the upper part of the floater 2.
- the slit nozzles 5 are installed at two locations in the traveling direction 10 of the belt-shaped substrate, and the respective gas ejection directions 51 face each other. Therefore, the gas ejected from the slit nozzle 5 is trapped between the strip-shaped base material 1 and the top plate 6 on the upper part of the floater to generate a static pressure, and the static pressure supports the strip-shaped base material 1 in a floating state.
- FIG. 2 shows a cross section taken along line A-A ′ of the floater 2 shown in FIG.
- a plurality of rib plates 4 are provided upright on the top plate 6 above the floater 2 in the widthwise direction 11 of the strip-shaped substrate, and the rib plates 4 allow the gas ejected from the slit nozzles 5 to rise. Is suppressed from flowing out in the width direction 11 of the strip-shaped substrate, and a static pressure is stably generated between the strip-shaped substrate 1 and the top plate 6, so that the strip-shaped substrate 1 can be stably floated. ..
- a plurality of rib plates are provided upright in the strip-shaped substrate advancing direction 10 from the viewpoint of suppressing the flow of the gas jetted from the slit nozzle 5 in the strip-shaped substrate advancing direction 10. Good. Further, at both outer sides of the rib plate 4, that is, at both width ends of the top plate 6 in the width direction 11 of the belt-shaped substrate, a height higher than that of the rib plate 4 for preventing the belt-shaped substrate from meandering. A tall side plate 3 is erected.
- the meandering correction ability of the strip-shaped substrate 1 included in the float 2 shown in FIGS. 1 and 2 will be described with reference to FIG.
- the gas flow path between the side plate 3 on the meandering side and the strip-shaped base material 1 becomes narrow, so that it is generated on the lower surface of the strip-shaped base material 1.
- the static pressure F0 becomes high. Therefore, the floating amount of the strip-shaped base material 1 on the meandering side becomes large, and the strip-shaped base material 1 is inclined as shown in FIG.
- the static pressure F0 acting on the lower surface of the strip-shaped substrate 1 acts as a force in the direction perpendicular to the substrate surface.
- This force can be divided into a vector of vertical force and a vector of horizontal force.
- the vertical force becomes the levitation force Fu that supports the weight of the strip-shaped substrate 1, and the horizontal force corrects the meandering of the strip-shaped substrate 1.
- the end portion of the strip-shaped base material 1 needs to be sufficiently close to the side plate 3, and for that reason, a certain amount of meandering must occur.
- the conventional floater 2 described above is effective for large meandering, but can hardly expect the meandering correction force Fc for small meandering.
- the inventors examined a meandering correction method that is effective even for small meanders.
- the meandering correction force Fc can be generated even with a small amount of meandering by forcibly inclining the strip-shaped substrate 1 with the meandering correction ability of the floater as a hint, and the present invention is realized. Came to develop.
- a nozzle for injecting gas is installed below the base material on the upstream side or the downstream side of the floater 2, and by adjusting the position of the nozzle and the gas pressure, the center of the width direction of the base material 11 in the width direction of the strip base material 11 A tilt is imparted to the base material by making a difference in the rotational moment around the center of the floater, and the meandering correction force Fc due to the fluid force (static pressure) of the floater is applied to operate the base material tilt on the floater. It is a method of straightening.
- a meandering correction gas nozzle 7 for imparting an inclination to the strip-shaped base material 1 is installed below the base material in the vicinity of the floater 2 to form a meandering correction device 20.
- the present invention has an advantage that the belt-shaped base material 1 is not damaged because it is non-contact. It is preferable to install two or more meandering correction gas nozzles 7 on both sides in the width direction 11 of the belt-shaped base material so that the base material can be inclined regardless of which side the base material meanders.
- the rotational pressure about the center of the strip-shaped substrate in the width direction is set by making a difference in the gas pressure injected from the meandering correction gas nozzle 7 on both sides in the strip-shaped substrate width direction 11. Can be operated. At that time, the meandering can be corrected by increasing the pressure on the side where the base material meanders.
- the installation position of the meandering correction gas nozzle 7 is preferably closer to the floater 2 so that the inclination of the steel plate on the floater 2 can be changed by the gas injection with good responsiveness. .. As shown in FIG. 5, the center-to-center distance between the most upstream floater 2 in the group of floaters 2 and the transport roll 9 immediately upstream of the floater 2, the center-to-center distance between two adjacent floaters 2, and the floater 2 described above.
- the installation position of the meandering correction gas nozzle 7 (installation distance K of the meandering correction gas nozzle 7 from the center of the floater K ) Is preferably installed within S / 2 in the longitudinal direction of the substrate. That is, the meandering correction gas nozzle 7 is installed so that the gas can be jetted to the base material within the range up to the lowest point of the suspension curve (catenary) formed by the base material between the floater and the upstream or downstream floater or the transfer roll. Preferably.
- the position at which the gas is jetted to the strip-shaped substrate is farther from the floater than the above position, the effect of tilting the substrate on the floater and the responsiveness are insufficient.
- the gas flow from the floater nozzle changes due to the gas injection of the additional meandering correction gas nozzle, which affects the static pressure for the substrate to float stably on the floater. Therefore, it is preferable to separate from the end of the floater in the longitudinal direction of the belt-shaped substrate. More preferably, the position is 100 mm or more away from the end of the floater.
- An example in which the center distance between the most downstream floater and the transport roll immediately downstream of the floater is S is shown in FIG.
- the gas pressure of the meandering correction gas nozzle 8 is preferably adjusted to 0 (gas stopped) or 0.1 P or more and 10 P or less. This is because if the pressure is too high, the behavior of the base material changes abruptly, causing instability of the strip running. Also, the floater 2 is tilted with a force higher than its floating force (static pressure), This is because there is a high possibility that contact between the strip 2 and the strip-shaped substrate 1 will occur. Further, if the pressure is too low, it is necessary to increase the opening area of the meandering correction gas nozzle in order to impart an inclination to the base material, which deteriorates the responsiveness.
- the gas pressure of the meandering correction gas nozzle is preferably adjusted in proportion to the total tension of the strip-shaped substrate.
- the distance L between the position 12 of the strip-shaped substrate when the meandering straightening gas nozzle is not used and the upper end of the meandering straightening gas nozzle is preferably H or more downward when the average floating amount of the strip-shaped substrate on the floater is H. Since the belt-like base material vertically vibrates due to the floating of the gas, if the meandering correction nozzle position is higher than the position 12, the risk of contact between the nozzle and the belt-like base material increases. Regarding the upper limit of the distance L for separating the meandering straightening nozzle from the strip-shaped substrate, it is preferable to install the meandering straightening gas nozzle tip within 20D when the nozzle diameter or the slit width is D for a slit nozzle.
- the distance L for separating the meandering correction nozzle from the strip-shaped substrate is preferably in the range of H to 20D, more preferably 1.5H to 15D.
- the average flying height H is the average value of the total width of the strip-shaped substrate from the top of the rib plate when the rib plate is present, and when the rib plate is not present, as shown in FIG. , Is defined as the average value of the distance from the top plate of the floater over the width of the strip-shaped substrate.
- the meandering correction gas nozzle opening is formed in the base material width direction of the strip-shaped base material. It is preferable to make the slit shape long.
- the slit shape also includes a shape in which a plurality of nozzles are densely arranged in the width direction of the base material.
- the angle ⁇ for inclining the strip-shaped substrate 1 on the floater 2 by the gas injection from the meandering correction gas nozzle 7 should be within ⁇ 0.3 to 6 ° with respect to the horizontal plane, depending on the substrate width and the flying height. Is preferred. If the absolute value of the inclination angle ⁇ is less than 0.3 °, the amount of inclination of the strip-shaped substrate is too small to generate a sufficient meandering correction force. On the other hand, when the absolute value of the inclination angle ⁇ is more than 6 °, the base material needs to be floated higher on the floater, which deteriorates the stability of the strip. More preferably, the angle ⁇ for inclining the strip-shaped base material on the floater is in the range of ⁇ 0.5 to 5 °.
- the meandering correction gas nozzle 7 is preferably provided with a mechanism for separating and retracting from the belt-shaped base material 1 in case of not using the meandering correction function.
- a cylinder such as an electric or hydraulic cylinder can be used as a method of adjusting the distance of the meandering correction gas nozzle 7 from the strip-shaped substrate 1.
- the meandering speed in the transfer device that floats the strip-shaped substrate with a floater is very fast because the frictional force (restraining force in the width direction) does not act on the strip-shaped substrate. It is necessary to control it well. Therefore, it is preferable to measure the meandering amount on the exit side of the conveying device (floater group) and feed back the measured value to control the pressure of the meandering correction gas nozzle. It is also effective to measure the shape of the strip-shaped base material before the conveying device, predict the meandering amount tendency, and feed forward the result to control the gas pressure of the meandering correction gas nozzle 7.
- the material for the meandering straightening gas nozzle is not particularly limited, but is preferably a material that can withstand a high temperature environment and a corrosive environment in an annealing furnace or a drying furnace. Ceramics, steel, stainless steel (SUS) and the like are preferably used. Further, it is preferable that a tip of the meandering correction gas nozzle is provided with a guard so that damage to the nozzle can be suppressed when the gas nozzle comes into contact with the base material.
- the material of the guard is preferably a material that can withstand high temperatures and corrosive environments, ceramics, steel, stainless steel (SUS), or the like.
- the number of blowers that supply gas to the meandering correction gas nozzle may be one or more.
- gas is repeatedly supplied to and stopped from a plurality of meandering correction gas nozzles, so it is preferable to have a switching valve so that which nozzle is supplied with gas or stopped can be switched. Since it is difficult to instantaneously inject and stop the gas in a large capacity blower, it is preferable that one system of the switching valve be provided with an escape port capable of injecting the gas to a place that does not affect the strip-shaped substrate. By letting the gas escape without stopping the blower, it becomes possible to repeat the gas injection from the meandering correction gas nozzle and the stop with good response by the switching valve.
- the time required for returning (meandering response time (meandering correction ability)) and occurrence of scratches were evaluated.
- the center-to-center distance between the most upstream floater and the transport rolls immediately upstream thereof and the center-to-center distance between the most downstream floater and the transport rolls immediately downstream thereof were all 10 m in the above-mentioned transport device.
- the meandering correction gas nozzle was arranged on the exit side of the fifth floater from the entrance side of the substrate.
- the meandering correction gas nozzle was provided with two slit-shaped openings of 10 mm ⁇ 600 mm on both sides in the width direction of the substrate.
- the end portion of the opening 600 mm was installed so as to project to the edge side of 50 mm from the widthwise center of the base material and to the outside of the base material edge portion by 50 mm under the condition that the base material did not meander.
- the gas pressure of the meandering correction gas nozzle was adjusted to a range of 0 to 10 kPa in gauge pressure.
- floater side plates are installed in the floater at a widthwise interval of 1500 mm and a side plate height of 50 mm.
- the floater shape has a nozzle spacing of 1100 mm in the longitudinal direction of the strip-shaped substrate, a length in the steel sheet traveling direction of 1500 mm, and a length in the steel sheet width direction of 1500 mm.
- the nozzle opening slit width was 20 mm.
- the substrate tension during transportation was 0.6 kg / mm 2 , and the substrate transportation speed was 100 m / min.
- the flying height is the distance from the top of the rib plate (from the top plate when there is no rib plate) to the average height position in the steel plate width direction.
- the above meandering amount was measured by detecting the steel plate edge using a two-dimensional laser sensor in the vicinity of the first conveyor roll that passed through the drying furnace.
- the scratches were visually inspected on the outlet side of the drying furnace under a sufficiently bright fluorescent lamp.
- the technology of the present invention is not limited to the strip steel plate described in the above embodiments, but can be applied to strip metal plates such as aluminum plates and copper plates, and strip substrates such as plastic films and paper.
