However, in Patent Document 1, there is a possibility that the film (hereinafter referred to as a base material) may be misaligned. This is carried out in a state where little tension is applied for a certain distance in order to prevent the base material W softened by high temperature from being stretched by tension after the base material coated with the coating liquid is dried. Therefore, there is a possibility that the position of the base material may be displaced in the width direction. Then, there is a problem that the base material cannot be wound up cleanly due to this. There is also a problem that the base material deviates from the transport roll (hereinafter referred to as a transport roller).

The present invention has been made in view of the above problems, and an object of the present invention is to provide a base material position adjuster and a base material transfer system capable of adjusting the position of a strip-shaped base material to be transported in the width direction. It is supposed to be.

In order to solve the above problems, the base material position adjuster of the present invention is a base material position adjuster that adjusts the position of the band-shaped base material to be conveyed in the width direction, and is a position where the base material is sent from upstream to downstream. The adjustment transfer roller and the base material in the position adjustment transfer roller face the position adjustment transfer roller so as to overlap at least a part of the base material when they are in a predetermined position in the width direction, and during normal transfer.

Since they can be in contact with each other, the position of the base material can be adjusted more easily.

Further, the position adjusting transfer roller is characterized by being a suction roller.

According to this configuration, since the position adjusting transfer roller is a suction roller, even if the position adjusting roller is separated from the base material, it is based on the upstream side and the downstream side of the position adjusting transfer roller. Since the tension applied to the material can be adjusted independently, the base material can be wound up on the downstream side even if the tension applied to the base material on the upstream side of the position adjusting transfer roller is lowered to the extent that the base material hangs down. Is.

Further, a plurality of the position adjusting rollers are provided, and at least one set of the position adjusting rollers is tilted so that the rotation axes of the rotation axes form a substantially V shape, and the positions are independently attached to and separated from the position adjusting transfer rollers. It is characterized by doing.

According to this configuration, the base material is guided in the direction in which the position of the base material is desired to be adjusted by having at least a set of position adjusting rollers in which the axes of rotation of each other are tilted to form a substantially V shape. By sandwiching the base material with the position adjustment transfer roller, the position adjustment roller suitable for It becomes possible to easily adjust the position of the base material by guiding.

Further, at least a part of the position adjusting roller is arranged at a position overlapping with the end portion of the base material in the width direction when the base material is in the predetermined position.

According to this configuration, at least a part of the position adjusting roller is arranged at a position overlapping with the end portion of the base material in the width direction when the base material is in a predetermined position, so that the position adjusting roller is positioned. Even if there is a possibility that a problem may occur due to contact of a position adjusting roller such as a coating film with the base material when sandwiching the base material with the adjusting transfer roller, the position adjusting roller contacts the base material. It is possible to correct the misalignment of the base material without doing so.

In order to solve the above problems, the base material transport system of the present invention corrects the positional deviation in the width direction of the strip-shaped base material transported by roll-to-roll, and the base material is placed in an appropriate position.

Will be described later), and the base material W unwound from the unwinding roller 21 is transported by being wound up by the winding roller 22 via the transport roller 23. In this coating device 3, the coating liquid is applied by the coating unit 31 and the coating liquid is dried by the drying unit 35 until the base material W unwound from the unwinding roller 21 is wound up by the winding roller 22. .. This makes it possible to obtain the base material W to which the coating liquid is applied. The coating liquid in this embodiment is, for example, metal ink or the like.

Further, on the downstream side of the drying portion 35, a base material position adjusting machine 1 for adjusting the position of the base material W in the width direction is provided, and the position shift (hereinafter, position) of the base material W being transported in the width direction is provided. When the sensor 24 detects (referred to as displacement), the position of the base material W is adjusted to correct the displacement. The width direction referred to here is a direction orthogonal to the long direction of the base material W.

The coating unit 31 is located on the transport path of the base material W by the base material transfer system 2, and is for applying the coating liquid to the base material W. In the present embodiment, a predetermined pattern is formed on the upper surface of the base material W by ejecting droplets of the coating liquid onto the base material W according to the shape of a predetermined pattern (for example, the shape of a circuit pattern) by an inkjet method. do.

Further, in the present embodiment, the base material W is a long film formed in a band shape, and is made of, for example, a transparent PET.

The coating unit 31 has a coating head 32, an imaging unit 33, and a suction stage 34.

The coating head 32 has a substantially flat surface facing the base material W thereof, and has a plurality of nozzle openings (not shown) on the surface. This nozzle is connected to a tank (not shown) in which the coating liquid is stored via a pipe (not shown), and the nozzle is filled with the coating liquid.

Each nozzle is individually connected to a discharge mechanism (not shown) provided inside the coating head 32, and each discharge mechanism is controlled by a control unit (not shown) to discharge the coating liquid from each nozzle. , It is configured to be able to control the operation of not discharging. The discharge mechanism referred to here is a mechanism that discharges a coating liquid by changing the volume of a piezo valve or the like. Further, the control unit referred to here is a so-called computer (hereinafter, treated in the same manner).

Further, the coating head 32 is attached to a coating head moving means (not shown) that moves the coating head 32 in the X-axis direction and the Y-axis direction. The movement of the coating head 32 is controlled by the control unit, and the coating head 32 is moved so that the coating head 32 can discharge the coating liquid to a predetermined position.

The image pickup unit 33 is one or a plurality of CCD cameras in the present embodiment, and is attached to an image pickup unit moving means (not shown) that moves the image pickup unit 33 in the X-axis direction and the Y-axis direction.

The image pickup unit 33 captures a characteristic mark such as an alignment mark (not shown) formed on the base material W, the control unit analyzes the coordinates of the alignment mark, and the coating head 32 paints from the result. Control the position where the liquid is applied.

The suction stage 34 is for sucking and fixing the base material W, and the surface facing the base material W is substantially flat, and has a plurality of suction hole openings (not shown) on the surface. There is. The suction hole is connected to a decompression means (not shown) such as a vacuum pump, and when the decompression means operates, gas is sucked from the suction hole to adsorb and fix the base material W.

With the configuration of these coating units 31, the base material W transported by the base material transport system 2 is adsorbed and fixed to the stage 33, the alignment mark on the base material W is imaged by the image pickup unit 33, and the coordinates of the alignment mark are captured by the control unit. Is analyzed, and the position of the coating head 32 and the like are controlled from the result, and the coating liquid is applied to a predetermined position.

The drying unit 35 is located downstream of the coating unit 31 in the transport path of the base material W, and is for heating and drying the coating liquid on the base material W with hot air, and has a drying furnace 36 and a conveyor 37. are doing.

The drying furnace 36 is a box-shaped device having a space through which the base material W passes and openings serving as inlets and outlets for the base material W. A plurality of air holes (not shown) that blow out hot air on the surface that forms the internal space of the drying furnace 36 and that faces the surface of the base material W to which the coating liquid is applied (hereinafter referred to as the coating surface). Is provided, and hot air is blown to the coated surface. As a result, the volatilization of the solvent on the coated surface is promoted, and the coating liquid dries and hardens.

Here, in order to prevent the base material W from being deformed unevenly due to the drying by the drying oven 36 and the heat over the long direction of the base material W, the base material W is dried so as to make the time during which the hot air hits the entire base material W uniform. The base material W is transported in the furnace 36 at a constant speed.

At this time, the transfer of the base material W in the drying furnace 36 is performed in a state where the tension applied to the base material W is lowered by supporting the base material W by the conveyor 37.

Further, while the coating liquid is applied by the coating unit 31 by adsorbing the base material W by the adsorption stage 34 as described above, the drying unit 35 needs to convey the coating liquid at a constant speed, so that the coating unit W and the coating unit 31 are applied. A buffer made of the base material W is formed between the drying portion 35 and the drying portion 35.

In the drying furnace 36 of the present embodiment, hot air is applied to the base material W, but when the base material W is fluttered by the hot air, a drying means for irradiating the base material W with infrared rays instead of the hot air is provided. You may use it.

As described above, the base material transfer system 2 has a take-up roller 21, a take-up roller 22, a plurality of transfer rollers 23, and a sensor 24, and further includes a base material position adjuster 1.

The unwinding roller 21 is for supplying the base material W to the downstream side, and has a cylindrical shape. The rotation of the unwinding roller 21 is driven and controlled by a control unit (not shown) to unwind the base material W at a predetermined speed.

The take-up roller 22 is for taking up the base material W unwound by the unwinding roller 21, and has a cylindrical shape. Like the unwinding roller 21, the take-up roller 22 is driven and controlled in rotation by a control unit, and winds up the base material W while applying a predetermined tension to the base material W.

The transport roller 23 passes through the base material W unwound by the unwinding roller 21 until it is wound up by the winding roller 22. It has a cylindrical shape or a cylindrical shape. A plurality of transfer rollers 23 are provided, and a part or all of the transfer rollers 23 are driven by a control unit in the same manner as the unwinding roller 21 and the winding roller 22. Controlled, the transfer roller 23 conveys the base material W while controlling the rotation so that a predetermined tension is applied to the base material W.

Further, a part or all of the transfer rollers 23 among the plurality of transfer rollers 23 may be suction rollers that can independently adjust the tension applied to the base material W on the upstream side and the downstream side of the transfer rollers 23. The suction roller referred to here is connected to a decompression means (not shown) such as a vacuum pump, has a large number of intake ports (not shown) on the outer peripheral surface of the roller, and is connected to the intake port by the operation of the decompression means. A suction force is generated, and when the base material W comes into contact with the outer peripheral surface of the roller, the base material W is sucked and held. The transport roller 13, which is a suction roller, has a cylindrical shape.

Here, there is a possibility that the base material W may be misaligned until the base material W unwound by the unwinding roller 21 is wound up by the winding roller 22 via the transport roller 23. In particular, this misalignment is more likely to occur immediately downstream of the dry portion 35. This is because the base material W coated with the coating liquid by the coating unit 31 is dried by the drying unit 35, and then the base material W softened at a high temperature is stretched and deformed by tension in FIG. 1. This is because it is necessary to transport the base material W with a low tension enough to form a droop for a certain distance as in the droop transport portion 25 shown in 1.

The sensor 24 is for detecting the positional deviation of the base material W in the width direction. Specifically, the sensor 24 is for observing the position of the end portion of the base material W in the width direction, and the base material W deviates from the position during normal transport (details will be described later) and is out of the allowable range. At that time, the measurement result of the end position of the base material W by the sensor 24 is out of the permissible range, and the control unit determines that the base material W is misaligned in response to the measurement result. In the present embodiment, the base material W is arranged in the vicinity of both ends in the width direction in the base material W during normal transfer so as to be located in the vicinity of the transfer roller 23. When the sensor 24 detects the displacement of the base material W, the sensor 24 transmits the detected result to the control unit (not shown). Further, the sensor 24 is, for example, an optical sensor. The sensor 24 may be arranged in the vicinity of the end portion in the width direction of the base material W during normal transfer so as to be located in the vicinity of the transfer roller 23.

The base material position adjuster will be described with reference to FIGS. 1 and 2.

FIG. 2 shows an enlarged plan view of the chain line portion a of FIG. 1, and also shows the base material position adjusting machine 1 included in the base material transport system 2 in the present embodiment.

The base material position adjusting machine 1 is for adjusting the position of the base material W, and has a position adjusting roller 11 and a position adjusting transfer roller 13.

Further, in the present embodiment, the base material position adjuster 1 is preferably located immediately downstream of the drying portion 35 in which the above-mentioned base material W is likely to be displaced, and particularly, as shown in FIG. 1, the drying portion. It is preferable that the position is immediately downstream of the hanging transport portion 25 formed on the downstream side of the 35.

The position adjusting transfer roller 13 is one of a plurality of transfer rollers 23, and as described above, the tension applied to the base material W on the upstream side and the downstream side of the position adjustment transfer roller 13 can be independently adjusted. It is good to have a good suction roller.

The position adjusting roller 11 is for guiding the base material W having a misalignment to an appropriate position T, and the rotating surface is made of an elastic body such as rubber. Further, it has a rotating shaft 12 which is a shaft for rotating the position adjusting roller 11.

As shown in FIG. 1, the position adjusting roller 11 faces the position adjusting transport roller 13 and is provided apart from the base material W during normal transport. Here, the base material W is within a predetermined margin of error centering on an ideal transport state in which the base material W is transported without any displacement of the base material W during normal transport. It means when it is being transported. The position of the end portion of the base material W in the ideal transport state is the proper position T of the base material W shown by the chain line in FIG. 2 (hereinafter, treated in the same manner). Further, the position adjusting roller 11 in a separated state is represented by a two-dot chain line in FIG.

Further, as shown in FIG. 2, the position adjusting roller 11 in the present embodiment is positioned in the plane when the base material W in the position adjusting transport roller 13 is at an appropriate position T in the width direction. There is.

In this embodiment, a plurality of position adjusting rollers 11 are provided. Here, at least one set of the position adjusting roller 11a and the position adjusting roller 11b are tilted so that the rotating shaft 12a and the rotating shaft 12b form a substantially V shape as shown in FIG. Here, the inclinations of the position adjusting rollers 11a and the position adjusting rollers 11b are the respective rotation axes 12 at the positions when the base material W is sandwiched between the position adjusting transport rollers 13 and the position adjusting transfer rollers 13 as described later. Each of the rotary shaft 12a and the rotary shaft 12b is tilted in the transport direction from the width direction of the base material W, and is also tilted with respect to the shaft core G which is the shaft core of the position adjusting transport roller 13. The shaft core here refers to a shaft when it is assumed that the shaft exists at the center of the roll as in the shaft core G shown in FIG.

Further, each of the plurality of position adjusting rollers 11 is connected to the position adjusting roller control means (not shown). The position adjusting roller control means is controlled by a control unit, and a plurality of position adjusting rollers 11 are independently brought close to the base material W, and the base material W is sandwiched between the position adjusting transport rollers 13. Further, the operation of separating the position adjusting roller 11 from the base material W is also performed by controlling the position adjusting roller control means by the control unit. The position adjusting roller control means is composed of, for example, a linear guide, a motor, or the like. The position adjusting roller control means is controlled by the control unit when the sensor 24 described above detects the positional deviation of the base material W and the information is transmitted to the control unit. Further, the sensor 24 is arranged so as to be located in the vicinity of the position adjusting transfer roller 13. Further, the position adjusting roller 11 in contact with the base material W is represented by a solid line in FIG.

Here, when the position adjusting roller 11 comes into contact with the conveyed base material W, it rotates due to a frictional force, and at that time, a force in a direction orthogonal to the direction of the rotation axis 12 is applied to the base material W. Specifically, when the position adjusting roller 11a is brought close to the base material W and the base material W is sandwiched between the position adjusting transport roller 13 as shown in FIG. 2, the position adjusting roller 11a exerts on the base material W. Since the force direction B has components of the direction A to the right of the paper surface and the direction C to the top of the paper surface, the base material W is conveyed while moving in the direction C on the paper surface. On the other hand, when the position adjusting roller 11b is brought close to the base material W and the base material W is sandwiched between the position adjusting transport rollers 13, the base material W is transported while moving downward on the paper surface.

At this time, the position adjusting roller 11 that is brought close to the base material W and sandwiches the base material W with the position adjusting transport roller 13 is selected to be suitable for correcting the positional deviation of the base material W. For example, when the base material W is displaced downward from the paper surface as shown in FIG. 2, the position adjusting roller 11 corrects the position of the base material W to the proper position T. It is necessary to guide the base material W in the direction C, which is the direction on the paper surface. Therefore, the position adjusting roller 11a is selected as the position adjusting roller 11 that is brought close to the base material W. Then, this is brought close to the base material W, and the base material W is sandwiched between the position adjusting transfer roller 13. The selection of the position adjusting roller 11 here is performed by the control unit.

Further, the position adjusting roller 11 may be located at an end portion in the width direction in the plane of the base material W during normal transportation.

The effect of the base material transfer system 2 having the above-described configuration in the present embodiment will be described as follows.

In the base material transfer system 2 of the present embodiment, as described above, the base material position adjuster 1 is provided on the immediately downstream side of the sag transfer unit 25, which is on the downstream side of the drying unit 35.

Generally, for a certain distance on the downstream side of the drying portion 35, the base material W is conveyed with low tension in order to prevent the base material W softened by high temperature from being stretched and deformed by tension. ing. Here, since the base material W is conveyed in a state where almost no tension is applied to the base material W, the base material W is displaced. If the transfer of the base material W is continued while this misalignment is left unattended, not only the base material W cannot be wound up neatly on the take-up roller 22, but also the base material W deviates from the transfer roller 23 and the transfer itself becomes. There is a risk that it will not be possible.

Therefore, the base material W is conveyed at an appropriate position T by correcting the positional deviation caused in the base material W by the base material position adjusting machine 1 provided on the downstream side of the drying portion 35 as in the present embodiment. It becomes possible.

Specifically, as shown in FIG. 2, the sensor 24 detects that the position of the base material W is displaced from the appropriate position T. At this time, as shown in FIG. 1, it is suitable for correcting the misalignment of the base material W among the plurality of position adjustment rollers 11 which face the position adjustment transfer roller 13 and are provided apart from the base material W. The position adjusting roller 11 (in the case of FIG. 2, the position adjusting roller 11a) is brought close to the base material W, and the base material W is sandwiched between the position adjusting transport roller 13. As a result, the base material W is conveyed while moving in the direction C on the paper surface, so that the base material W can be corrected to an appropriate position T. The position adjusting roller 11 sandwiching the base material W with the position adjusting transport roller 13 is separated from the base material W when the correction of the positional deviation of the base material W is completed (hereinafter, treated in the same manner). ).

Here, among the plurality of position adjusting rollers 11 provided as in the present embodiment, at least one set of position adjusting rollers 11 is tilted so that the rotating shafts 12 of each other form a substantially V shape. Therefore, a position adjusting roller 11 suitable for correcting the misalignment of the base material W is selected and approached, and the base material W is sandwiched between the position adjusting transport roller 13 to correct the misalignment of the base material W. Therefore, it is possible to correct the positional deviation of the base material W without the need for a mechanism for adjusting the inclination of the rotating shaft 12.

Specifically, the base material W is not the method of misalignment shown in FIG. 2, but the position adjusting roller 11b is used as the base material instead of the position adjusting roller 11a even when the base material W is misaligned toward the paper surface. By sandwiching the base material W with the position adjusting transfer roller 13 in close proximity to W, the base material W can be moved downward on the paper surface, so that the positional deviation of the base material W can be corrected.

Further, it is preferable that at least the rotating surface of the position adjusting roller 11 is made of an elastic body.

As a result, when the base material W is sandwiched between the position adjusting transfer rollers 13, the rotating surface of the position adjusting roller 11 is crushed, and the rotating surface and the base material W can be in contact with each other by at least a line. Since the position of the material W can be easily guided by the appropriate position T, it becomes possible to more easily correct the positional deviation of the base material W.

Further, it is preferable that the position adjusting roller 11 is located at the end portion in the width direction in the plane of the base material W during normal transportation.

As a result, as shown in FIG. 2, the position adjusting roller 11 is located at the end of the base material W, so that the position adjusting roller 11 comes into contact with the coating portion where the coating liquid is applied on the base material W. It is possible to correct the misalignment of the base material W. Therefore, it is possible to correct the positional deviation of the base material W without damaging the coated portion.

Here, like the position adjusting roller 11a shown in FIG. 2, the rotating shaft 12 having an inclination capable of exerting a force for moving the base material W in the direction opposite to the direction in which the base material W is displaced is applied to the base material W. The position adjusting roller 11 to be held may be provided at the end of the base material W located in the direction opposite to the direction in which the base material W is displaced. Specifically, the position adjusting roller 11a located at the end of the base material W on the upper side of the paper surface in FIG. 2 may have an inclination so as to exert a force for moving the base material W on the lower side of the paper surface.

As a result, when correcting the positional deviation of the base material W, a force for moving the base material W so as to pull the base material W from the end portion in the width direction of the base material W can be applied to the base material W. It is possible to avoid wrinkling of the base material W when correcting the positional deviation of the material W.

Further, it is preferable that at least the position adjusting transport roller 13 of the transport rollers 13 is a suction roller.

As a result, even when the position adjusting roller 11 is separated from the base material, the tension applied to the base material W on the upstream side and the downstream side of the position adjusting transport roller 13 can be independently adjusted. Therefore, even if the tension applied to the base material W on the upstream side of the position adjusting transfer roller 13 is lowered so that the base material W hangs down, the base material W can be wound on the downstream side.

[Second Embodiment]
Next, the base material transfer system 2 according to the second embodiment of the present invention will be described with reference to the drawings. The same reference numerals are given to the same configurations as those of the first embodiment, and detailed description thereof will be omitted. In the present embodiment, the configuration is the same as that in the first embodiment except that the position adjusting roller 11 is one.

FIG. 3 shows an enlarged plan view of the chain line portion a of FIG. 1 of the base material transfer system 2 according to the second embodiment of the present invention, and is a base material included in the base material transfer system 2 according to the present embodiment. It also shows an enlarged plan view of the position adjuster 1.

FIG. 4 is a diagram showing one variation of the base material transfer system 2 according to the second embodiment of the present invention.

The base material position adjusting machine 1 included in the base material transport system 2 in the present embodiment has one position adjusting roller 11 as shown in FIG. 3, and adjusts the inclination of the rotation shaft 12 of the position adjusting roller 11. It also has a tilt adjustment function (not shown).

When the sensor 24 detects the displacement of the base material W, the tilt adjusting function adjusts the tilt of the rotating shaft 12 according to the detected displacement. Specifically, the inclination of the rotating shaft 12 is adjusted so that a force for moving the base material W in the direction opposite to the direction of the displacement of the base material W detected by the sensor 24 can be applied to the base material W.

More specifically, when the misalignment of the base material W detected by the sensor 24 occurs in the downward direction on the paper surface as shown in FIG. 3, the base material W is moved upward on the paper surface as in the position adjusting roller 11 shown in FIG. The inclination of the rotating shaft 12 is adjusted so that the force moving to can be applied to the base material W. Then, the position adjusting roller 11 whose inclination of the rotating shaft 12 is adjusted is brought close to the base material W, and the base material W is sandwiched between the position adjusting transport roller 13 to move the base material W upward on the paper surface. Correct the misalignment of the base material W.

On the other hand, when the misalignment of the base material W detected by the sensor 24 occurs in the upward direction on the paper surface as shown in FIG. 4, the force for moving the base material W downward on the paper surface as shown in the position adjusting roller 11 shown in FIG. The inclination of the rotating shaft 12 is adjusted so that the above can be exerted on the base material W. Then, the position adjusting roller 11 having adjusted the inclination of the rotating shaft 12 is brought close to the base material W, and the base material W is sandwiched between the position adjusting transport roller 13 to move the base material W downward on the paper surface. Correct the misalignment of the base material W.

As a result, the tilt of the rotating shaft 12 can be adjusted by the tilt adjusting function so that the tilt is suitable for correcting the positional deviation of the base material W as shown in FIGS. 3 and 4, so that the position can be adjusted. Even with a simple configuration in which there is only one roller 11, it is possible to correct the positional deviation of the base material W.

Although the embodiments of the present invention have been described in detail with reference to the drawings, the configurations and combinations thereof in each embodiment are examples, and the configurations may be added or omitted within a range not deviating from the gist of the present invention. Replacements and other changes are possible. For example, the arrangement positions and the quantities of various rolls including the coating portion 31, the drying portion 35, the transport roll 23, etc. provided on the transport path of the base material W are not limited to those shown in the figure, and are suitable for the intended use. You may change it. Further, the position where the base material position adjuster 1 is provided is not limited to the downstream side of the drying portion 10, and may be provided at a place where the position of the base material may be displaced. Further, the arrangement of the position adjusting roller 11 is not limited to the plane of the base material W, and at least a part of the position adjusting roller 11 is based on the position adjusting roller 11 when the base material W is sandwiched between the position adjusting roller 11 and the position adjusting transport roller 13. It does not matter if it is in a position where it can come into contact with the material W. Further, the arrangement of the position adjusting roller 11 is not limited to the end portion in the width direction of the base material W, and may be any position as long as it does not come into contact with the coating portion when approaching the base material W. Further, the method of shifting the position of the base material W is not limited to that shown in the figure. Also, the invention is not limited by embodiments, but only by the claims.
