Description

The present invention relates to a winding device and a winding method for recovering masking tape stuck to a strip.

Generally, when performing partial plating treatment on a strip of material such as metal or resin, masking tape is pasted on the parts that do not require plating so that only the desired portions of the strip surface can be plated. There is a method of performing plating treatment in this state.

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

The masking tape attached to the strip is peeled off and collected after the plating process. Since the length of the strips to be plated is extremely long, masking tape winding devices that are linked to the running speed of the strips running on the plating line are generally used to collect the masking tape. .

As a conventional masking tape winding device, for example, the invention of Patent Document 1 has been disclosed by the present applicant. Patent Document 1 discloses that a photographing device photographs the position where masking tape starts to peel off from a running strip, and the rotation speed of a bobbin around which the masking tape is wound is automatically changed based on the photographed positional information of the peeling position. A winding device is disclosed.

Japanese Patent Application Publication No. 2015-124431

In such a winding device, when peeling off the masking tape, it is first necessary to manually peel off the masking tape from the strip and set it on the bobbin of the winding device. In recent years, the line speed of plating lines has been increased to improve productivity, and as the line speed increases, it becomes difficult to manually peel off and set masking tape in time, and to ensure work safety. There was a risk that it would become 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 masking tape in response to the increase in line speed.

In order to solve the above problems, the present invention provides a winding device for winding masking tape peeled off from a running strip, comprising a winding machine for winding the masking tape, and a winding machine for winding the masking tape; an accumulation drive section disposed on an upstream side that includes an accumulation mechanism that changes the running speed of the strip material, and that drives the accumulation mechanism to control the running speed of the strip material led out from the accumulation mechanism; At least one speed sensor that measures the running speed of a strip introduced into the mechanism or derived from the accumulation mechanism, and at least one of the set value of the running speed of the strip derived from the accumulation mechanism and the speed sensor. A masking tape winding device is provided in which the accumulation drive section is controlled based on the running speed of the strip measured at .

In this masking tape winding device , a strip winding device may be provided downstream of the masking tape winding device. Furthermore, a plating device may be provided upstream of the masking tape winding device. Furthermore, a strip unwinding device may be provided upstream of the plating device.

Further, according to the present invention, in the masking tape stripping step of winding up the masking tape peeled off from the strip, the front end of the masking tape is peeled off from the strip, and the masking tape comprising the accumulating mechanism and the winding machine is After wrapping the peeled masking tape around a take-up roll provided in the winding machine of the winding device, the running speed of the strip drawn out from the accumulation mechanism is increased , and the running speed of the strip drawn out from the accumulation mechanism is increased. A masking tape winding method comprising: a speed sensor for measuring running speed; and controlling the winding speed of the winding machine based on the running speed of the strip measured by the speed sensor. provided.

In this masking tape winding method , a plating process may be provided upstream of the masking tape peeling process. Furthermore, a strip unwinding device provided upstream of the plating process may include a strip feeding step for feeding the strip to which masking tape is attached to the plating process. Further, the method may include a strip winding step of winding the strip from which the masking tape has been peeled off, using a strip winding device provided downstream of the masking tape winding device. The material of the strip may be metal or resin.

In the masking tape winding device and the winding method of the present invention, when the masking tape is peeled off from the strip, the running speed of the strip can be changed by the accumulation mechanism. Therefore, even if the line speed increases, by setting the traveling speed of the strip to a speed at which the masking tape can be easily peeled off, it is possible to avoid being unable to complete the task of peeling off and setting the masking tape in time. As described above, according to the present invention, it is possible to facilitate the task of peeling off masking tape in response to increased line speeds.

1 is a plan view showing a schematic configuration of a masking tape winding device according to an embodiment of the present invention. FIG. 3 is an explanatory diagram of the accumulation mechanism, showing a state in which the speed of the strip material drawn out from the accumulation mechanism is controlled to be slow. FIG. 2 is an explanatory diagram of the accumulation mechanism, showing a state in which control is performed to increase the speed of the strip material drawn out from the accumulation mechanism.

The present invention is suitably applied to hoop plating (reel-to-reel plating) in which a strip of metal or the like to which a masking tape is attached is continuously subjected to full-surface plating or partial (striped) plating. Therefore, the embodiments of the present invention will be described based on a winding device (hereinafter simply referred to as "winding device") that winds up a masking tape provided in a hoop plating line. The specific process of the hoop plating line is as follows: metal strip feeding (uncoiler) process → plating process (plating process) → masking tape stripping process (masking tape winding device) → metal strip This is the process of winding up the material (reel (winding machine)). In addition, in this specification and the drawings, elements having substantially the same functional configuration are designated by the same reference numerals and redundant explanation will be omitted.

As shown in FIG. 1, a winding device 1 according to the present embodiment includes a winding machine 5 that winds up masking tape 3 peeled off from a traveling strip 2, and a winder 5 that changes the running speed of the strip 2. It is equipped with an accumulation mechanism 6. In FIG. 1, the strip 2 runs from right to left. In FIG. 1, the X direction is the running 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 accumulation mechanism 6 is located upstream (on the right side in FIG. 1) of the winding machine 5 (adjacent to it), and the strip material 2 led out from the accumulation mechanism is then introduced into the winding machine 5. be done. Although not shown, on the upstream side of the winding device 1 (upstream side of the accumulation mechanism 6), there is an uncoiler (strip material unwinding machine) that feeds out the strip material 2, and a plating device that performs plating processing on the strip material 2. are arranged, and the strip material 2 sent out from the uncoiler and plated by the plating device is continuously introduced into the winding device 1. Although not shown, a reel (strip material winding machine) for winding the strip material 2 is disposed downstream of the winding device 1 (downstream of the winding device 5). The strip material 2 from which the masking tape 3 has been peeled off is wound up by a winding reel (a strip winding machine).

In the embodiment illustrated in FIG. 1, the winding machine 5 includes two winding sections (a first winding section 5a and a second winding section 5b) on both sides of the strip 2. The first winding section 5a winds up the masking tape 3 on one side of the strip 2, and the second winding section 5b winds up the masking tape 3 on the other side. Since the first winding section 5a and the second winding section 5b have similar configurations, in the following explanation, the description of the second winding section 5b which overlaps with the first winding section 5a will be explained. is omitted.

As shown in FIG. 1, the winder 5 includes a support base 10 provided below the strip material 2 running in the X direction, and a support base 10 provided on the upper surface of the support base 10 so as to sandwich the running strip material 2. It is equipped with three rotatable fulcrum rolls 11 arranged alternately. Each of the fulcrum rolls 11 is arranged so as to be in contact with the running strip 2, and the second and third fulcrum rolls 11 from the upstream side are arranged so as to be in contact with the running strip 2, and the second and third fulcrum rolls 11 from the upstream side are This is a fulcrum roll (hereinafter referred to as "peeling fulcrum roll 11a") on which the peeled off masking tape 3 is hooked.

Furthermore, a heater 12 (panel heater, etc.) is provided on the upper surface of the support base 10 to heat the surface of the running strip 2. Thereby, the adhesive force of the masking tape can be weakened, and the masking tape can be easily peeled off from the strip 2.

A stand 15 having the same height as the support stand 10 is provided in the first winding section 5a. On the top surface of the stand 15, there is a take-up roll 16 for winding up the masking tape 3 peeled off from one side of the strip 2 by the peel-off fulcrum roll 11a, and the peel-off fulcrum roll 11a and the take-up roll 16. A relay roll 17 and a stripping bridle roll 18 are provided between which the masking tape 3 is relayed.

The relay roll 17 is configured to follow and rotate when the masking tape 3 is wound up. On the other hand, the take-up roll 16 and the stripping bridle roll 18 are equipped with a drive device, and the stripping bridle roll 18 is configured to change the rotational speed based on the running speed of the strip 2. drives are controlled. The drive device for the take-up roll 16 is controlled to change the rotational speed in accordance with the load applied to the take-up roll 16 by the masking tape 3 conveyed from the stripping bridle roll 18.

Note that the second winding section 5b that winds up the masking tape 3 peeled off from the other surface of the strip 2 also has a similar configuration. Therefore, by assigning the same reference numerals, duplicate explanations will be omitted.

The accumulation mechanism 6 has a configuration in which a pair of guide roll sets 22 and 23 are arranged between an introduction roll 20 and a lead-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 accumulation mechanism 6 (the introduction roll 20, the lead-out roll 21, and the guide rolls 24 and 25 are all driven rolls, but a pair of guide roll sets 22 and 23 (the guide roll 24 and the guide roll 25) are configured such that the distance between them can be changed by driving the accumulation drive unit 26. That is, as shown in FIG. ) and the other guide roll set 23 (guide rolls 25) can be moved away from each other, and as shown in FIG. 3, one guide roll set 22 ( The guide roll 24) and the other guide roll set 23 (guide roll 25) can be moved closer to each other.

An upstream speed sensor 30 of the accumulation mechanism 6 is provided on the upstream side of the accumulation mechanism 6 to measure the speed of the strip material 2 introduced into the accumulation mechanism 6. Further, on the downstream side of the accumulation mechanism 6, there is provided a downstream speed sensor 32 of the accumulation mechanism 6, which measures the speed of the strip 2 led out from the accumulation mechanism 6. Note that in this embodiment, the downstream speed sensor 32 is arranged downstream of the winder 5. As will be described later, the drive of the accumulation 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 calculated based on the speed of the strip material 2 measured by at least one of the upstream speed sensor 30 and the downstream speed sensor 32. It is configured so that it can be changed.

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

FIG. 1 shows a state in which a strip 2 is introduced into a winding device 1 and a masking tape 3 is automatically wound up in a winder 5 in accordance with the traveling speed of the strip 2.
When introducing the strip material 2 into the winding device 1 in this way, the dummy material is first sent out from the uncoiler (not shown), introduced into the plating device (not shown) and the winding device 1, and the rear end of the dummy material is By connecting the tip of the strip material 2 to the dummy material, the strip material 2 sent out from the uncoiler can be introduced into the winding device 1 following the dummy material. Note that the uncoiler for sending out the dummy material and the uncoiler for sending out the strip material 2 may be provided separately.
The procedure for winding up the masking tape 3 from the strip 2 in the winder 5 is as follows: First, after the tip of the strip 2 reaches the first winding section 5a following the dummy material, , an operator peels off the front end of the masking tape 3 stuck to one side of the strip 2. Then, while pulling the front end 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 on the peeling fulcrum roll 11a, the relay roll 17, and the peeling bridle roll 18 in this order, and finally the first winding portion 5a is wound. 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 stand 10, and the masking tape 3 is set on the first winding section 5a.

Thereafter, 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 peeled off from one side of the strip 2 is automatically peeled off in accordance with the running speed of the running strip 2 and wound onto the take-up roll 16.

Incidentally, the same operation is also performed in the second winding section 5b, and the masking tape 3 stuck to the other surface of the strip 2 is set in the second winding section 5b. As a result, the masking tape 3 that has been peeled off from the other side of the strip 2 is automatically peeled off in accordance with the running speed of the strip 2, and is transferred to the winding roll 16 of the second winding section 5b. It will be rolled up in the same way.

By the way, in recent years, the line speed of plating lines has been increasing, and if the line speed of the plating process is set high, it will not be possible to manually peel off and set the masking tape 3 in the masking tape stripping process. There are cases. Therefore, if the line speed is set so high in the plating process that it is difficult to manually peel off the masking tape 3 from the strip, the line speed shown in Figure 2 should be set when manually peeling off the masking tape 3 from the strip. As shown, the drive of the accumulation drive unit 26 moves one guide roll set 22 (guide roll 24) and the other guide roll set 23 (guide roll 25) away from each other. As a result, the speed of the strip 2 introduced into the accumulation mechanism 6 is absorbed between the pair of guide rolls 22 and 23, and the strip 2 guided out from the accumulation mechanism 6 via the delivery roll 21 runs. Speed is reduced.
As a result, the running speed of the strip 2 introduced into the winder 5 decreases, and the operator runs the strip at a slow speed in the first winding section 5a and the second winding section 5b of the winder 5. The front end of the masking tape 3 stuck to the material 2 is peeled off, and the peeled off masking tape 3 is easily wound around a peeling fulcrum roll 11a, a relay roll 17, a peeling bridle roll 18, and a winding roll 16 in this order. be able to. In this case, the setting value of the traveling speed of the strip (downstream side of the accumulation mechanism 6) derived from the accumulation mechanism 6 suitable for the above-mentioned stripping and wrapping work, and the downstream speed sensor 32 of the accumulation mechanism 6 or the upstream side The drive of the accumulation drive unit 26 is controlled based on the running speed of the strip 2 measured by the speed sensor 30 or both of these speed sensors, and the strip runs on the upper surface of the support base 10 led out from the accumulation mechanism 6. It is preferable to appropriately control the traveling speed of No. 2 to the set value. Then, by rotationally driving the stripping bridle roll 18 and the winding roll 16, the masking tape 3 stripped from the strip 2 is transferred to the winding roll 16 of the first winding section 5a and the second winding section 5b, respectively. It gets wound up.

Further, after the masking tape 3 peeled off from the strip 2 is set in the first winding part 5a and the second winding part 5b, as shown in FIG. 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 accumulation mechanism 6 via the lead-out roll 21 increases temporarily. That is, after the front end of the masking tape 3 is peeled off from the strip 2 and the peeled masking tape 3 is wound around a winding roll 16 provided in the winder 5, the strip 2 is led out from the accumulation mechanism 6. 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 is already in the first winding section 5a and the second winding section 5b, including the stripping fulcrum roll 11a, the relay roll 17, the stripping bridle roll 18, and the winding roll 16. Since the stripping bridle roll 18 and the take-up roll 16 are rotated, the masking tape 3 peeled off from the strip 2 can be smoothly wound onto the take-up roll 16. . In this case, the rotational speed of the stripping bridle roll 18 is changed based on the running speed of the strip 2 running on the upper surface of the support base 10, which is measured by the downstream speed sensor 32 of the accumulation mechanism 6. The rotation speed of the take-up roll 16 is changed according to the load applied to the take-up roll 16 by the masking tape 3 conveyed from the take-up bridle roll 18. Therefore, even if the speed of the strip 2 temporarily increases, the masking tape 3 peeled off from the strip 2 is wound onto the take-up roll 16 with a constant load. The rotational speed of the stripping bridle roll 18 or the take-up roll 16 is preferably set to be higher than the traveling speed of the strip 2 measured by the downstream speed sensor 32 of the accumulation mechanism 6.
Note that the increase in the running speed of the strip 2 derived from the accumulation mechanism 6 depends on the set value of the running speed of the strip in the plating process, the upstream speed sensor 30 or the downstream speed sensor 32 of the accumulation mechanism, Alternatively, it is preferable to control the drive of the accumulation drive unit 26 based on the running speed of the strip 2 measured by both of these speed sensors, and appropriately control the running speed of the strip 2 to the set value.

As described above, according to the present embodiment, the accumulation mechanism 6 is driven when the masking tape 3 is peeled off from the traveling strip 2 and set in the first winding section 5a and the second winding section 5b. With this, the running speed of the strip 2 can be changed. For example, when the running speed of the strip material 2 led out from the accumulation mechanism 6 is increasing due to an increase in the line speed of the plating line, the pair of guide roll sets 22 are driven by the accumulation drive section 26. , 23 are spaced apart from each other. As a result, the running speed of the strip 2 introduced into the accumulation mechanism 6 is absorbed between the pair of guide rolls 22 and 23, and the running speed of the strip 2 led out from the accumulation mechanism 6 via the lead-out roll 21 is Speed is reduced. As a result, the traveling speed of the strip 2 introduced into the winder 5 decreases, and the operator is forced to move at a slow traveling speed in the first winding section 5a and the second winding section 5b of the winding machine 5. The front end of the masking tape 3 pasted on the strip 2 is peeled off, and the peeled masking tape 3 is easily transferred to the peeling fulcrum roll 11a, the relay roll 17, the peeling bridle roll 18, and the take-up roll 16 in this order. Can be wrapped. Thereby, the masking tape 3 peeled off from the strip 2 can be easily set in the first winding section 5a and the second winding section 5b. Therefore, the masking tape 3 attached to the strip 2 will not peel off, or the masking tape 3 that has been peeled off will not break in the middle, and the masking tape 3 can be reliably peeled off and rolled up. Can be done. Thereby, it is possible to prevent plating defects from occurring in the product due to the masking tape 3 remaining on the surface of the strip.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to such examples. It is clear that those skilled in the art can come up with various changes or modifications within the scope of the technical idea described in the claims, and these naturally fall within the technical scope of the present invention. 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 (equipment), a similar accumulation mechanism is installed between the outlet side of the strip unwinder and the plating device, and the plating process It is also possible to adjust the running speed of the strip material 2 when carrying out this process. In addition, an accumulation mechanism is installed between the output side of the masking tape winding device 1 and the strip winding device, so that the strip material 2 is You can also adjust the running speed. These accumulation mechanisms (different from the accumulation mechanism 6 provided in the masking tape winding device 1) connect and disconnect the dummy material and the strip material (material to be plated) during the plating process and the strip winding process. This can be done efficiently without reducing the line speed. The heater 12, the intermediate roll 17, and the stripping bridle roll 18 may be omitted, and the downstream speed sensor 32 of the accumulation mechanism 6 may be provided between the accumulation mechanism 6 and the winding device 1.
Further, the accumulation mechanism 6 only needs to be able to control the speed of the strip material 2, and is not limited to the above-mentioned mechanism. For example, one of the guide rolls may be fixed and only the other guide roll may be moved. Furthermore, a strip winding device may be provided downstream of the masking tape winding device 1. In that case, the strip winding machine may include a step of winding up the metal strip from which the masking tape has been removed. Further, a plating device may be provided upstream of the masking tape winding device 1. In that case, a strip unwinding device may be provided upstream of the plating device.
Further, a drive roll is provided with a drive device for conveying the strip between the strip unwinding device and the masking tape winding device 1, or between the masking tape winding device 1 and the strip winding device. (bridle roll) is preferably provided. In this case, the accumulating drive section is based on the set value of the running speed of the strip (on the downstream side of the accumulating mechanism 6) derived from the accumulating mechanism 6 suitable for the stripping and winding work, and the rotational speed of the driving roll. 26, the running speed of the strip 2 that runs on the upper surface of the support stand 10, which is led out from the accumulation mechanism 6, can be appropriately controlled to 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 or the downstream speed sensor 32, but in order to control the running speed of the strip 2 more accurately, it is necessary to use a speed sensor. It is desirable to be prepared.
The set value of the traveling speed of the strip (downstream side of the accumulation mechanism 6) derived from the accumulation mechanism 6 suitable for the stripping and wrapping work, and the downstream speed sensor 32 or the upstream speed sensor 30 of the accumulation mechanism 6. , or control the driving of the accumulation drive unit 26 based on the running speed of the strip 2 measured by both of these speed sensors, and run the strip 2 on the upper surface of the support base 10 led out from the accumulation mechanism 6. It is preferable to appropriately control the speed to the set value.
In addition, the setting value of the traveling speed of the strip drawn out from the accumulation mechanism 6 (on the downstream side of the accumulation mechanism 6) suitable for the stripping and wrapping work, the strip unwinding roll of the strip unwinding device, the The drive of the accumulation drive unit 26 is controlled based on the rotational speed of at least one of the strip winding rolls of the material winding device, and the running speed of the strip 2 traveling on the upper surface of the support base 10 led out from the accumulation mechanism 6 is controlled. It is also possible to control so that the value is the set value. However, since the strip is unwound or wound up on a strip unwinding roll and a strip take-up roll, the diameter of the unwinding roll and take-up roll, including the thickness of the strip, changes. Control becomes difficult. Therefore, it is preferable to control the running speed of the strip based on the rotational 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, and similarly, a reel for winding the strip material 2 is installed downstream of the winding device 1 (downstream of the winding machine 5). (a strip winder) and a reel for winding up a dummy material (a dummy material winder) may be provided separately.

In the winding device according to the embodiment of the present invention, a masking tape peeling test was conducted under the following conditions.
・Test material (strip material): Copper strip material of plate thickness 0.64 mm x width 97 mm ・Masking tape for plating: Hitalex K-2165B (manufactured by Hitachi Chemical Co., Ltd.)
Size: 2 striped tapes of 4.6 mm and 50 mm. Paste 2 stripes on one side of the copper strip at a distance. Running speed of the strip: 15 m/min.
- Stripping bridle speed: 15.6m/min.

In the example, even if the line speed of the plating line (process) is increased (15 m/min), by driving the accumulation mechanism, the traveling speed of the strip drawn out from the accumulation mechanism is reduced to 0 m/min. It was confirmed that the masking tape could be easily removed from the strip by hand. In addition, after the masking tape that has been peeled off as described above is wound around the peeling fulcrum roll, relay roll, peeling bridle roll, and take-up roll of the winding machine, the accumulating mechanism is driven to lead out the masking tape from the accumulating mechanism. It was possible to increase the running speed of the strip material to the line speed of the plating line (process).
