Description

The present invention relates to a winding device and a winding method for collecting masking tape attached to a strip material.

Generally, when partial plating is performed on a strip of material such as metal or resin, masking tape is attached to the portion that does not require plating so that only the desired portion of the strip surface can be plated. Then, there is a method of performing the plating process in that state.

For example, when plating is applied to only one surface of the strip surface, masking tape is attached to the entire other surface. When so-called stripe plating is applied to the strip material, masking tape is attached to a part of the strip material surface. When the plating process is performed with the masking tape attached in this way, plating is applied to the other portions of the surface of the strip material except the portion to which the masking tape is attached.

The masking tape attached to the strip is stripped off and collected after the plating process. Since the length of the strip to be plated is very long, a masking tape winding device linked to the traveling speed of the strip traveling on the plating line is generally used for collecting the masking tape. ..

As a conventional masking tape winding device, for example, the present applicant has disclosed the invention of Patent Document 1. In Patent Document 1, the position where the masking tape starts to peel off from the traveling strip is photographed by a photographing device, and the rotation speed of the bobbin around which the masking tape is wound is automatically changed based on the position information of the photographed peeling position. The winding device that is designed to do so is disclosed.

In such a winding device, when the masking tape is peeled off, it is necessary to first manually peel off the masking tape from the strip material and set it on the bobbin of the winding device. In recent years, the line speed of the plating line has been increased in order to improve productivity, and if the line speed is increased, the work of manually peeling off the masking tape and setting it will not be in time, and the safety of the work will be ensured. Could be difficult.

The present invention has been made in view of the above circumstances, and an object of the present invention is to facilitate the work of peeling off the masking tape in response to an increase in line speed.

Further, according to the present invention, in the process of stripping the masking tape for winding the masking tape stripped from the strip material, the front end portion of the masking tape is stripped from the strip material, and the masking tape including an accumulator mechanism and a winder is used. After winding the peeled masking tape around the winding roll provided in the winding machine of the winding device, the traveling speed of the strip material derived from the accumulator mechanism is increased. The method is provided.

Further, the strip winding device provided on the downstream side of the masking tape winding device may have a strip winding step for winding the strip from which the masking tape has been peeled off. The material of the strip may be metal or resin.

In the masking tape winding device and winding method of the present invention, when the masking tape is peeled off from the strip material, the traveling speed of the strip material can be changed by an accumulator mechanism. Therefore, even if the line speed is increased, by setting the traveling speed of the strip material to a speed at which the masking tape can be easily peeled off, it is possible to avoid the work of peeling off the masking tape and setting it in time. As described above, according to the present invention, it is possible to facilitate the work of peeling off the masking tape in response to the increase in line speed.

The present invention is suitably applied to hoop plating (reel-to-reel plating) in which a strip of metal or the like to which masking tape is attached is continuously plated on the entire surface or partially plated (striped). Therefore, the description of the embodiment of the present invention will be described based on a winding device (hereinafter, simply referred to as “winding device”) for winding the masking tape provided on the hoop plating line. The specific process of the hoop plating line is as follows: metal strip feeding (uncoiler (winding machine)) process → plating process (plating process) → masking tape stripping process (masking tape winding device) → metal strip.

Further, in the present specification and the drawings, elements having substantially the same functional configuration are designated by the same reference numerals to omit duplicate description.

As shown in FIG. 1, the winding device 1 in the present embodiment changes the traveling speed of the winding machine 5 for winding the masking tape 3 stripped from the traveling strip-shaped strip 2 and the strip 2. The accumulator mechanism 6 is provided. In FIG. 1, the strip 2 runs from right to left. In FIG. 1, the X direction is the traveling direction of the strip 2. Therefore, in FIG. 1, the right side is the upstream side and the left side is the downstream side. The accumulator mechanism 6 is arranged (adjacent) on the upstream side (right side in FIG. 1) of the winder 5, and the strip 2 derived from the accumulator mechanism is then introduced into the winder 5. Will be done. Although not shown, on the upstream side of the winding device 1 (upstream side of the accumulator mechanism 6), an uncoiler (strip material unwinding machine) that sends out the strip material 2 and a plating device that plating the strip material 2 are performed. Is arranged, and the strip 2 that has been sent out from the uncoiler and plated by the plating apparatus is continuously introduced into the winding apparatus 1. Further, although not shown, a reel (strip material winder) for winding the strip material 2 is arranged on the downstream side of the winding device 1 (downstream side of the winder 5), and the winding device 1 The strip 2 from which the masking tape 3 has been peeled off is wound by a reel (strip winder).

In the embodiment illustrated in FIG. 1, the take-up machine 5 includes two take-up portions (first take-up portion 5a, second take-up portion 5b) on both sides of the strip 2 sandwiching the strip material 2. The first winding portion 5a winds up the masking tape 3 on one surface of the strip 2, and the second winding portion 5b winds up the masking tape 3 on the other surface. Since the first winding unit 5a and the second winding unit 5b have the same configuration, in the following description, the description of the second winding unit 5b having the content overlapping with the first winding unit 5a will be described. Is omitted.

As shown in FIG. 1, the winder 5 is provided on a support base 10 provided below the strip 2 traveling in the X direction and on the upper surface of the support base 10 so as to sandwich the traveling strip 2. It is provided with three rotatable fulcrum rolls 11 arranged in a staggered manner. Each fulcrum roll 11 is arranged so as to be in contact with the traveling strip 2, and the second and third fulcrum rolls 11 from the upstream side are from the strip 2 at the time of winding the masking tape described later. This is a fulcrum roll (hereinafter, referred to as “stripping fulcrum roll 11a”) on which the stripped masking tape 3 is hooked.

Further, a heater 12 (panel heater or the like) for heating the surface of the traveling strip 2 is provided on the upper surface of the support base 10. As a result, the adhesive force of the masking tape can be weakened, and the masking tape can be easily peeled off from the strip material 2.

The first winding portion 5a is provided with a base 15 having a height equivalent to that of the support base 10. On the upper surface of the base 15, a winding roll 16 for winding the masking tape 3 stripped from one surface of the strip 2 by the stripping fulcrum roll 11a, a stripping fulcrum roll 11a, and a winding roll 16 A relay roll 17 and a stripping bridle roll 18 for relaying the masking tape 3 are provided between the two.

On the other hand, the take-up roll 16 and the stripping bridle roll 18 are provided with a drive device, and the stripping bridle roll 18 is such that the rotation speed is changed based on the traveling speed of the strip 2. Drive device is controlled. The drive device of the take-up roll 16 is controlled so that the rotation speed is changed according to the load applied to the take-up roll 16 by the masking tape 3 conveyed from the stripping bridle roll 18.

The second winding portion 5b for winding the masking tape 3 peeled off from the other surface of the strip 2 also has the same configuration. Therefore, by assigning a common reference numeral, duplicate description will be omitted.

The accumulator mechanism 6 has a configuration in which a pair of guide roll sets 22 and 23 are arranged between the introduction roll 20 and the take-out roll 21. One guide roll set 22 includes a plurality of guide rolls 24, and similarly, the other guide roll set 23 also includes a plurality of guide rolls 25. Each roll provided in the accumulator mechanism 6 (introduction roll 20, derivation roll 21, guide roll 24, 25 are driven rolls, but a pair of guide roll sets 22, 23 (guide roll 24 and guide roll 25)). Is configured so that the distance between them can be changed by driving the accumulator drive unit 26. That is, as shown in FIG. 2, one of the guide roll sets 22 (guide roll 24) is driven by the accumulator drive unit 26. ) And the other guide roll set 23 (guide roll 25) can be moved so as to be separated from each other, and as shown in FIG. 3, one guide roll set 22 () is driven by the accumulator drive unit 26. The guide roll 24) and the other guide roll set 23 (guide roll 25) can be moved so as to be close to each other.

On the upstream side of the accumulator mechanism 6, an upstream speed sensor 30 of the accumulator mechanism 6 for measuring the speed of the strip 2 introduced into the accumulator mechanism 6 is provided. Further, on the downstream side of the accumulator mechanism 6, a speed sensor 32 on the downstream side of the accumulator mechanism 6 for measuring the speed of the strip 2 led out from the accumulator mechanism 6 is provided. In this embodiment, the downstream speed sensor 32 is arranged on the downstream side of the winder 5. As will be described later, the drive of the accumulator drive unit 26 can be controlled based on the speed of the strip 2 measured by the upstream speed sensor 30, the downstream speed sensor 32, or both of these sensors. .. That is, the distance between the pair of guide roll sets 22 and 23 (guide roll 24 and guide roll 25) is determined based on the speed of the strip 2 measured by at least one of the upstream speed sensor 30 and the downstream speed sensor 32. It is configured to be changeable.

The winding device 1 in the present embodiment is configured as described above. Next, a method of winding the masking tape 3 peeled off from the strip 2 will be described using the winding device 1 having the above configuration.

FIG. 1 shows a state in which the strip 2 is introduced into the winding device 1 and the masking tape 3 is automatically wound by the winder 5 according to the traveling speed of the strip 2.
When the strip 2 is introduced into the winding device 1 in this way, the dummy material is first sent out from the anchorer (not shown), introduced into the plating device (not shown) and the winding device 1, and the rear end of the dummy material is introduced. By connecting the tip of the strip 2 to the strip 2, the strip 2 sent out from the uncoiler following the dummy material can be introduced into the winding device 1. An uncoiler that sends out the dummy material and an uncoiler that sends out the strip material 2 may be provided separately.
Then, as a procedure for setting the masking tape 3 to be wound from the strip 2 in the winder 5, first, after the tip of the strip 2 reaches the first winding portion 5a following the dummy material. , The worker peels off the front end portion of the masking tape 3 attached to one surface of the strip material 2. Then, while pulling the front end portion of the masking tape 3, the subsequent masking tape 3 is peeled off.
When the peeled masking tape 3 reaches a certain length, the masking tape 3 is hooked in the order of the stripping fulcrum roll 11a, the relay roll 17, and the stripping bridle roll 18, and finally the first winding portion 5a is wound up. Wrap the masking tape 3 around the roll 16. In this way, the masking tape 3 is peeled off from the strip 2 running on the upper surface of the support base 10, and the masking tape 3 is set in the first winding portion 5a.

After that, the drive device is operated to rotate the stripping bridle roll 18 and the take-up roll 16. As a result, the masking tape 3 stripped from one surface of the strip 2 is automatically stripped according to the traveling speed of the traveling strip 2, and is wound around the take-up roll 16.

The same operation is performed in the second winding section 5b, and the masking tape 3 attached to the other surface of the strip 2 is set in the second winding section 5b. As a result, the masking tape 3 stripped from the other surface of the strip 2 is automatically stripped according to the traveling speed of the traveling strip 2, and is applied to the winding roll 16 of the second winding portion 5b. It is wound up in the same way.

By the way, in recent years, the line speed of the plating line has been increased, and if the line speed of the plating process is set high, the work of manually peeling and setting the masking tape 3 in the masking tape peeling process cannot be completed in time. In some cases. Therefore, when the line speed is set so high that it is difficult to manually remove the masking tape 3 from the strip material in the plating process, when the masking tape 3 is manually peeled off from the strip material, FIG. As shown, by driving the accumulator drive unit 26, one guide roll set 22 (guide roll 24) and the other guide roll set 23 (guide roll 25) are moved so as to be separated from each other. As a result, the speed of the strip 2 introduced into the accumulator mechanism 6 is absorbed between the pair of guide roll sets 22 and 23, and the strip 2 led out from the accumulator mechanism 6 travels through the lead roll 21. The speed is reduced.
As a result, the traveling speed of the strip 2 introduced into the winder 5 is reduced, and in the first winding portion 5a and the second winding portion 5b of the winder 5, the operator can perform the strip at a slow speed. The front end of the masking tape 3 attached to the material 2 is peeled off, and the peeled masking tape 3 is easily wound in the order of the peeling fulcrum roll 11a, the relay roll 17, the stripping bridle roll 18, and the winding roll 16. be able to. In this case, the set value of the traveling speed of the strip (on the downstream side of the accumulator mechanism 6) derived from the accumulator mechanism 6 suitable for the stripping and winding work, and the downstream speed sensor 32 or the upstream side of the accumulator mechanism 6. The strip material that controls the drive of the accumulator drive unit 26 based on the traveling speed of the strip material 2 measured by the speed sensor 30 or both speed sensors and travels on the upper surface of the support base 10 derived from the accumulator mechanism 6. It is preferable to appropriately control the traveling speed of 2 to be the set value. Then, the masking tape 3 stripped from the strip 2 by the rotational drive of the stripping bridle roll 18 and the take-up roll 16 is applied to the take-up rolls 16 of the first take-up portion 5a and the second take-up portion 5b, respectively. It will be rolled up.

Further, after the masking tape 3 peeled off from the strip 2 is set in the first winding portion 5a and the second winding portion 5b, as shown in FIG. 3, a pair is driven by the accumulator driving unit 26. The guide roll sets 22 and 23 can be brought close to each other. In this case, when the pair of guide roll sets 22 and 23 are brought close to each other, the speed of the strip 2 led out from the accumulator mechanism 6 via the lead roll 21 is temporarily increased. That is, the front end portion of the masking tape 3 is peeled off from the strip material 2, the stripped material 2 is drawn out from the accumulator mechanism 6 after the peeled masking tape 3 is wound around the winding roll 16 provided in the winder 5. The running speed is increased until it becomes the same as the line speed of the plating process. However, the masking tape 3 peeled off from the strip 2 has already been removed from the stripping fulcrum roll 11a, the relay roll 17, the stripping bridle roll 18, and the winding roll 16 in the first winding portion 5a and the second winding portion 5b. Since the masking tape 3 is wound and set in this order, the masking tape 3 stripped from the strip 2 can be smoothly wound around the winding roll 16 by the rotational drive of the stripping bridle roll 18 and the winding roll 16. .. In this case, the rotation speed of the stripping bridle roll 18 is changed based on the traveling speed of the strip 2 traveling on the upper surface of the support base 10 measured by the downstream speed sensor 32 of the accumulator mechanism 6, and the stripping is also performed. The masking tape 3 conveyed from the take-up bridle roll 18 can change the rotation speed of the take-up roll 16 according to the load applied to the take-up roll 16. Therefore, even if the speed of the strip 2 is temporarily increased, the masking tape 3 stripped from the strip 2 is wound around the winding roll 16 with a constant load. It is preferable that the rotation speed of the stripping bridle roll 18 or the take-up roll 16 is set to be larger than the traveling speed of the strip 2 measured by the downstream speed sensor 32 of the accumulator mechanism 6.
The increase in the traveling speed of the strip 2 derived from the accumulator 6 is the set value of the traveling speed of the strip in the plating process and the upstream speed sensor 30 or the downstream speed sensor 32 of the accumulator. Alternatively, it is preferable to control the drive of the accumulator drive unit 26 based on the traveling speed of the strip 2 measured by both of these speed sensors, and appropriately control the traveling speed of the strip 2 to be the set value.

As described above, according to the present embodiment, when the masking tape 3 is peeled off from the traveling strip 2 and set in the first winding portion 5a and the second winding portion 5b, the accumulator mechanism 6 is driven. Therefore, the traveling speed of the strip 2 can be changed. For example, when the traveling speed of the strip 2 derived from the accumulator mechanism 6 is increased due to the increase in the line speed of the plating line, the pair of guide roll sets 22 are driven by the accumulator drive unit 26. , 23 are separated from each other. As a result, the traveling speed of the strip 2 introduced into the accumulator mechanism 6 is absorbed between the pair of guide roll sets 22 and 23, and the strip 2 led out from the accumulator mechanism 6 travels via the lead roll 21. The speed is reduced. As a result, the traveling speed of the strip 2 introduced into the winding machine 5 decreases, and the operator at the first winding portion 5a and the second winding portion 5b of the winding machine 5 at a slow traveling speed. The front end of the masking tape 3 attached to the strip 2 is peeled off, and the peeled masking tape 3 can be easily removed in the order of the stripping fulcrum roll 11a, the relay roll 17, the stripping bridle roll 18, and the winding roll 16. Can be wrapped. As a result, the masking tape 3 stripped from the strip 2 can be easily set in the first winding portion 5a and the second winding portion 5b. Therefore, the masking tape 3 attached to the strip 2 is not peeled off, or the stripped masking tape 3 is not cut off in the middle, and the masking tape 3 is surely peeled off and wound up. Can be done. As a result, it is possible to prevent the product from causing plating defects due to the remaining masking tape 3 on the surface of the strip material.

Although preferred embodiments of the present invention have been described above, the present invention is not limited to such examples. It is clear that a person skilled in the art can come up with various modifications or modifications within the scope of the technical idea described in the claims, and of course, the technical scope of the present invention also includes them. It is understood that it belongs to.

For example, when the strip 2 is sent out from the strip unwinder and plated in the plating process (device), a similar accumulator mechanism is installed between the lead-out side of the strip unwinder and the plating device, and the plating process is performed. It is also possible to adjust the traveling speed of the strip 2 when performing the above. Further, when an accumulator mechanism is installed between the lead-out side of the masking tape winding device 1 and the strip winding device to perform the winding (reel (winding machine)) process of the metal strip, the strip 2 You can also adjust the running speed. These accumulator mechanisms (different from the accumulator mechanism 6 provided in the masking tape winding device 1) connect and disconnect the dummy material and the strip material (material to be plated) in the plating process and the strip material winding process. It can be done efficiently without reducing the line speed of. The heater 12, the relay roll 17, and the stripping bridle roll 18 may be omitted, and the downstream speed sensor 32 of the accumulator mechanism 6 may be provided between the accumulator mechanism 6 and the winding device 1.
Further, the accumulator mechanism 6 is not limited to the above-mentioned one as long as the speed of the strip 2 can be controlled, and for example, one of the guide rolls may be fixed and only the other guide roll may move. Further, a strip winding device may be provided on the downstream side of the masking tape winding device 1. In that case, the strip winding machine may have a winding step of the metal strip that winds the strip from which the masking tape has been peeled off. Further, a plating processing device may be provided on the upstream side of the masking tape winding device 1. In that case, a strip unwinding device may be provided on the upstream side of the plating processing device.
Further, a drive roll provided with a drive device for transporting the strip material between the strip material unwinding device and the masking tape winding device 1 and at least one between the masking tape winding device 1 and the strip material winding device 1. (Bridle roll) is preferably provided. In this case, the accumulator drive unit is based on the set value of the traveling speed of the strip (on the downstream side of the accumulator mechanism 6) derived from the accumulator mechanism 6 suitable for the stripping and winding work and the rotation speed of the drive roll. The drive of 26 can be controlled, and the traveling speed of the strip 2 traveling on the upper surface of the support base 10 derived from the accumulator mechanism 6 can be appropriately controlled to be the set value. That is, the running speed of the strip 2 can be controlled by the drive roll without the upstream speed sensor 30 and the downstream speed sensor 32, but in order to control the running speed of the strip 2 more accurately, the speed sensor is used. It is desirable to prepare.
The set value of the traveling speed of the strip (on the downstream side of the accumulator mechanism 6) derived from the accumulator mechanism 6 suitable for the stripping and winding work, and the downstream speed sensor 32 or the upstream speed sensor 30 of the accumulator mechanism 6. Or, the drive of the accumulator drive unit 26 is controlled based on the traveling speed of the strip 2 measured by both of these speed sensors, and the strip 2 traveling on the upper surface of the support base 10 derived from the accumulator mechanism 6 travels. It is preferable to appropriately control the speed so as to have the set value.
Further, the set value of the traveling speed of the strip material (on the downstream side of the accumulator mechanism 6) derived from the accumulator mechanism 6 suitable for the stripping and winding work, and the strip material unwinding roll and the strip of the strip material unwinding device. The traveling speed of the strip 2 traveling on the upper surface of the support base 10 derived from the accumulator mechanism 6 by controlling the drive of the accumulator drive unit 26 based on the rotation speed of at least one of the strip winding rolls of the material winding device. Can also be controlled to be the set value. However, since the strip material is unwound or wound on the strip material unwinding roll and the strip material winding roll, respectively, the diameters of the unwinding roll and the winding roll including the thickness of the strip material change. It becomes difficult to control. Therefore, it is preferable to control the traveling speed of the strip based on the rotation speed of the drive roll.
Further, an uncoiler for sending out the dummy material and an uncoiler for sending out the strip material 2 may be provided separately. Similarly, a reel for winding the strip material 2 on the downstream side of the winding device 1 (downstream side of the winding machine 5). (Straw material winder) and a reel (dummy material winder) for winding the dummy material may be provided separately.

In the winding device according to the embodiment of the present invention, a test for peeling off the masking tape was carried out under the following conditions.
-Test material (strip material): Copper strip material with a thickness of 0.64 mm x width of 97 mm-Masking tape for plating: Hitarex K-2165B (manufactured by Hitachi Kasei Co., Ltd.)
