Description

In the present invention, when the subsequent foil material is connected to the preceding foil material and continuously processed, the preceding foil material stored when the sending of the preceding foil material with the connection of the subsequent foil material is stopped is sent out, The present invention relates to a vertical looper for storing a preceding foil material sent out when processing of the preceding foil material is delayed, and an operation method thereof.

When a long and strip-shaped metal article (strip material) is processed continuously (for example, heat treatment), in order to absorb the difference in processing speed between the processing step and the preceding process, the strip material is disposed between the preceding process and the processing step. A strip material retaining device (looper) is provided in which a certain amount of strip material is retained by zigzag running. The strip material retaining device is provided with a plurality of fixed rolls and a plurality of movable rolls arranged so as to be able to approach and separate from the fixed rolls in order to hang the strip material and make the zigzag travel. In order to adjust, a staying distance adjusting mechanism for moving the movable roll close to and away from the fixed roll is provided. Further, the strip retaining device is provided with a swiveling roll, and a strip shift prevention mechanism for correcting a shift (meandering) in the width direction of the strip generated when the strip is zigzag-running. Here, the strip material deviation prevention mechanism not only controls the turning speed of the swiveling roll based on the deviation amount detected by the width direction position detection mechanism of the strip material, but also turns the movable roll according to the raising / lowering amount of the lifting frame. By controlling the angle, the shift of the strip is corrected without applying an excessive twisting force to the strip (see, for example, Patent Document 1).

JP 2003-53414 A

In the strip material retention device described in Patent Document 1, when the distance between the fixed roll and the movable roll becomes long and the path length in the vertical direction becomes long, the load applied to the strip due to the weight of the strip becomes large and the strip width. Compressive force works in the direction. For this reason, the risk of squeezing deformation due to this compressive force increases as the strip thickness decreases. On the other hand, when the strip material retention device is used for the strip material in a wide range of plate thickness, each roll constituting the strip material retention device needs to have a configuration capable of passing a thick strip material. is there. However, since the roll has rigidity more than necessary for a strip having a thin plate thickness, there arises a problem that the roll inertia increases. For this reason, when a thin strip is passed through the strip retaining device, the roll inertia is large at the time of acceleration / deceleration of the strip, and there is a risk that the strip will slip on each roll and cause scratches. Therefore, when processing strips in a wide range of plate thickness (for example, from a very thin metal foil having a thickness of less than 100 μm to a non-ultra thin metal foil having a plate thickness of 100 μm or more and 300 μm or less) in one processing facility, the strip material is used. It becomes difficult to carry out stable passage with a staying device. In recent years, foil materials such as stainless steel and copper are often used in electronic devices, and the thickness of foil materials for electronic devices tends to be reduced as electronic devices become smaller and lighter. For this reason, when processing the foil material of the board | plate thickness of a wide range with one processing equipment, the strip material retention apparatus applicable to each board thickness is calculated | required.

Further, in the strip material retaining device described in Patent Document 1, when the lifting roll is brought close to the fixed roll, the lifting roll interferes with the frame supporting the fixed roll and the width direction position detection mechanism of the strip. Therefore, it is impossible to make the height position of the movable roll below the height position of the fixed roll. Therefore, when the strip material is first passed through the strip material retaining device, it is necessary to pass the strip material in a zigzag manner while being hooked on the fixed roll and the movable roll. For this reason, there exists a problem that work efficiency falls.

The present invention has been made in view of such circumstances, and a vertical looper capable of easily changing the plate configuration according to the thickness of the metal foil in a wide range of thickness, and capable of correcting meandering, and the same The purpose is to provide a driving method.

A plurality of elevating rolls arranged on a support member, and in a state A in which each elevating roll passes through a gap between each fixed roll, the gap between the plurality of fixed rolls and the plurality of elevating rolls In a state B in which the metal foil can run and each of the elevating rolls is not inserted between each of the fixed rolls and the mount is separated from the fixed roll, the zigzag is formed between the fixed rolls and the elevating rolls. In the vertical looper where the metal foil is hooked in a shape,
A meandering correction mechanism is provided that draws the metal foil from between the adjacent lifting rolls and adjusts the meandering of the metal foil at a position that does not contact the lifting rolls inserted between the fixed rolls.

In the vertical looper according to the present invention, it is preferable to change the mounting height of some or all of the plurality of fixed rolls.

The operation method of the vertical looper according to the present invention that meets the above-described object includes a plurality of fixed rolls arranged with gaps along the traveling direction of the strip-shaped metal foil, and a platform that moves up and down with respect to the fixed roll A plurality of elevating rolls disposed on the projecting support members, and in a state A in which each elevating roll is inserted through a gap between each fixed roll, the plurality of fixed rolls and the plurality of elevating rolls In the state B in which the ultrathin metal foil is inserted therebetween, and the lifting rolls are not inserted between the fixing rolls and the mount is separated from the fixing rolls, the fixing rolls and the respective fixing rolls In the operation method of the vertical looper that hooks and inserts the non-thin metal foil in a zigzag manner on the lifting roll ,
Provided with a meandering correction mechanism for pulling out the metal foil from between the adjacent lifting rolls at the central position and adjusting the meandering of the metal foil at a position where it does not come into contact with the lifting roll inserted between the fixed rolls. The meandering of the metal foil is adjusted .

In the vertical looper according to claims 1 and 2, for a metal foil having a wide plate thickness range with one vertical looper, the plate configuration can be easily selected according to the plate thickness and the plate configuration is easy. In addition, it is possible to correct the meandering that occurs during passage. As a result, it is possible to process metal foils in a wide range of plate thicknesses with one processing facility, and the facility cost can be suppressed. And, the state in which the metal foil is alternately hung on the fixed roll and the lifting roll and the metal foil is run in a zigzag shape, the metal foil is passed between the plurality of fixed rolls on the entry side and the plurality of lifting rolls. In a state where the metal foil taken out from the meandering correction mechanism and taken out from the meandering correction mechanism is passed between the plurality of fixing rolls on the exit side and the plurality of lifting rolls and discharged, each lifting roll is set to each fixing roll. This can be easily achieved by separating them. For this reason, the operation | work which latches metal foil on a fixed roll and a raising / lowering roll alternately, and arrange | positions in zigzag form can be performed efficiently in a short time.

In particular, in the vertical looper according to claim 2, by changing the mounting height of a part or all of the plurality of fixed rolls, in a state A in which each lifting roll is inserted through the gap between the fixed rolls, When the metal foil travels between the fixed roll and the plurality of elevating rolls, the number of contact between the upper surface of the fixed roll and the metal foil can be reduced to reduce scratches on the metal foil.

In the operating method of the vertical looper according to claim 3 , a plurality of fixed rolls and a plurality of lift rolls are provided in a state A in which each lift roll is inserted through a gap between each fixed roll for an extremely thin metal foil. The path length in the vertical direction of the ultrathin metal foil can be shortened by passing it between and the squeezing deformation by suppressing the compressive force acting on the ultrathin metal foil in the width direction due to its own weight. Can be prevented. In addition, it is possible to prevent the ultrathin metal foil from coming into contact with all the fixing and elevating rolls, reducing the occurrence of scratches due to slipping of the ultrathin metal foil on each roll during acceleration / deceleration of the ultrathin metal foil. it can.

In addition , since the metal foil can be adjusted, it is possible to prevent the occurrence of meandering even if the thin metal foil is passed through with low tension in order to prevent the occurrence of squeezing deformation. Can be prevented. As a result, the processing yield of ultrathin metal foil can be improved.

A vertical looper 10 according to an embodiment of the present invention has a strip-like metal foil (for example, a stainless steel foil or a copper foil having a thickness of 5 to 300 μm) 11 as shown in FIGS. A plurality of fixed rolls 12 arranged with gaps along the traveling direction, and a plurality of lifting rolls 15 arranged on a support member 14 that protrudes from a gantry 13 that moves up and down with respect to the fixed roll 12. For example, the metal foil 11 is drawn out from between the adjacent lifting rolls 15 at the center position at a position where it does not come into contact with the lifting rolls 15 inserted through the gaps between the fixed rolls 12 to adjust the meandering of the metal foil 11. A meandering correction mechanism 16 is provided. Details will be described below.

The fixed rolls 12 are arranged on a frame-shaped fixed mount 17 via a support member (not shown) so as to be parallel to each other and horizontal, and a wide gap is provided between the adjacent fixed rolls 12 at the center position. However, a gap having a width through which the elevating roll 15 can be inserted is formed between the other adjacent fixed rolls 12. The fixed base 17 constitutes a part of the frame 18 of the vertical looper 10 and is attached to a plurality of column members 20 erected on the installation base 19. Here, by adjusting the length of the support member, among the plurality of fixed rolls 12, the remaining fixed except for the fixed roll 12 disposed on one end side (for example, the metal foil entrance side) of the fixed mount 17. All the mounting height positions of the rolls 12 are held at the same height position, and are mounted lower than the mounting height position of the fixed roll 12 disposed on one end side.

When the lifting roll 15 is attached to the gantry 13, the adjacent lifting rolls 15 that are parallel to the fixed roll 12 and that are located at the center position of the pedestal 13 have a wide width formed between the adjacent fixed rolls 12 at the center position. The positions of the other lifting rolls 15 are adjusted so that the gaps formed between the adjacent fixed rolls 12 other than the center position can be inserted. Further, the gantry 13 is attached to the column member 20 via a lifting mechanism (not shown). Here, the elevating mechanism is, for example, a pair of sprockets provided at the upper and lower ends of each column member 20, an endless chain wound around the sprocket, and rotational power connected to one of the sprockets via a speed reducer. And a source. The gantry 13 is connected to one side chain of the endless chain wound around the pair of sprockets via an attachment member, and the balance weight is connected to the other side of the endless chain via the attachment member.

With such a configuration, as shown in FIG. 1A, the base 13 is brought close to the fixed base 17 to form a state A in which each lifting roll 15 is inserted through the gap between the fixed rolls 12. The metal foil 11 can be passed (running) between the plurality of fixed rolls 12 and the plurality of lifting rolls 15. In addition, as shown in FIG. 1B, in a state B in which the gantry 13 is lowered and separated from the fixed roll 12, the state is hooked on each fixed roll 12 and each lifting roll 15 in a zigzag manner. The metal foil 11 can be passed through.

Meandering correction mechanism 16 is above the fixed frame 17, is arranged to be supported by the column member 20 in a position not in contact with the lifting roller 15 inserted through the respective fixed rolls 12, the mounting base in which the opening 21 is formed in the center 22 and a frame-shaped installation base 24 held on the installation base 22 via a support member 23. Further, the meandering correction mechanism 16 is arranged in parallel with the swivel base 25 supported by a rotating shaft (not shown) provided on the installation base 24 and the fixed roll 12 (lifting roll 15) on both sides of the swivel base 25. The rotating rolls 26 and 26a are a pair, and a rotation driving source (not shown) that applies a rotation driving force to the rotating shaft. Furthermore, the meandering correction mechanism 16 includes an entrance guide roll 27 and an exit guide arranged in the opening 21 so as to be parallel to the fixed roll 12 (elevating roll 15) via a support member (not shown). An entry side deflection roll 29 provided downstream of the entry side guide roll 27 at a position below the roll 28 and the installation table 24, and an exit provided upstream of the exit side guide roll 28 at a position below the installation table 24. A side deflection roll 30 and a foil position detection sensor 31 that detects the end position of the metal foil 11 that has passed through the swirl roll 26a on the downstream side of the swirl rolls 26 and 26a provided as a pair without contact. Yes.

With the above-described configuration, in a state A in which each lifting roll 15 is inserted through the gap between each fixed roll 12, the plurality of fixed rolls 12 and the plurality of lifting rolls 15 disposed on the entry side of the metal foil 11. And the metal foil 11 taken out from the meandering correction mechanism 16 is passed between the plurality of fixed rolls 12 and the plurality of lifting rolls 15 arranged on the outlet side. The metal foil 11 is hooked on each fixed roll 12 and each lift roll 15 in the state B in which the gantry 13 on which the plurality of lift rolls 15 are arranged is separated from the fixed roll 12. The metal foil 11 taken out from the meandering correction mechanism 16 can be similarly passed in a zigzag manner and discharged by passing the foil 11 in a zigzag manner and flowing into the meandering correction mechanism 16.

In the meandering correction mechanism 16, the metal foil 11 passes through the entry side guide roll 27, is changed in direction by the entry side deflection roll 29, and is guided to the pair of turning rolls 26 and 26 a, and the turning rolls 26 and 26 a. The metal foil 11 that has passed through is changed in direction by the exit side deflection roll 30 and is discharged via the exit side guide roll 28. Here, when meandering occurs in the metal foil 11, the end position of the metal foil 11 detected by the foil position detection sensor 31 is a preset reference position (for example, when no meandering occurs) Of the metal foil 11), and the amount of deviation corresponds to the meandering distance.

Therefore, if the metal foil 11 meanders to the left (right) side with respect to the traveling direction, the left (right) side end position of the metal foil 11 is displaced to the left (right) side from the reference position. When the rotation shaft is rotated clockwise (counterclockwise) by a proportional angle, the swivel rolls 26 and 26a are swung clockwise (counterclockwise) via the swivel base 25 . As a result, the traveling direction of the metal foil 11 also changes in a clockwise direction (counterclockwise) in plan view, and the meandering of the metal foil 11 is corrected.

Then, the operating method of the vertical looper 10 which concerns on one embodiment of this invention is demonstrated. As shown in FIG. 2A, on the upstream side of the vertical looper 10, either one of the first and second unwinding reels 32 and 33 provided along the metal foil feeding direction is provided. A metal foil feeding device 35 provided with a welding machine 34 for welding the leading end portion of the succeeding metal foil fed from the other unwinding reel is arranged at the rear end portion of the preceding metal foil fed from the unwinding reel. .
First, a method of first passing the ultrathin metal foil 36 through the vertical looper 10 will be described.
The frame 13 of the vertical looper 10 is moved to the closest position to the fixed frame 17, and each lifting roll 15 is in a state A inserted through the gap between the fixed rolls 12. Next, for example, the ultrathin metal foil coil 37 formed by winding the ultrathin metal foil 36 on the first unwinding reel 32 is mounted. Then, while unwinding the ultrathin metal foil 36 from the ultrathin metal foil coil 37, the operator passes the ultrathin metal foil 36 over the second unwinding reel 33 and inside the welder 34, 18 is introduced into the vertical looper 10 from an inlet (not shown) via a looper entry-side guide roll 38 provided via a support member (not shown).

As shown in FIG. 2B, the ultrathin metal foil 36 introduced into the vertical looper 10 is inserted between the plurality of fixed rolls 12 and the plurality of lifting rolls 15 and reaches the center position. The ultrathin metal foil 36 is hooked on the lifting roll 15 provided on the inlet side of the meandering correction mechanism 16 at the center position of the gantry 13 to change the traveling direction, and the entrance guide roll provided in the meandering correction mechanism 16. 27. The swirl rolls 26 and 26a provided as a pair via the entrance-side deflection roll 29 are hooked on the swirl roll 26 on the upstream side.
Here, since the fixed roll 12 arranged on the most entrance side of the metal foil 36 of the fixed base 17 is attached so as to be higher than the other fixed rolls 12, the installation position of the looper entry side guide roll 38 is adjusted. Accordingly, when the ultrathin metal foil 36 is inserted between the plurality of fixed rolls 12 and the plurality of lifting rolls 15, the metal foil 36 comes into contact with the fixed roll 12 disposed on the most entrance side of the metal foil 36. In the state of being hooked on the lifting roll 15 provided on the entrance side of the meandering correction mechanism 16 at the center position of 13, so as not to contact any roll other than the lifting roll 15 provided on the entrance side at the center position of the gantry 13. it can.

The ultrathin metal foil 36 that has passed through the swirl roll 26 on the upstream side of the swirl rolls 26, 26a provided as a pair passes through the swirl roll 26a on the downstream side of the swirl rolls 26, 26a provided as a pair, A plurality of fixed rolls are passed through an exit side deflection roll 30 and an exit side guide roll 28 and are hooked by an elevating roll 15 provided on the exit side of the meandering correction mechanism 16 at the center position of the gantry 13 to change the traveling direction. 12 and a plurality of elevating rolls 15 are inserted and discharged out of the vertical looper 10 from an outlet (not shown). Here, by adjusting the installation position of the looper exit side guide roll 39 provided on the frame 18 via a support member (not shown), the ultrathin metal foil 36 and the plurality of fixed rolls 12 and the plurality of lifts When it is inserted between the rolls 15 and discharged from the outlet to the vertical looper 10, it can be prevented from contacting any roll other than the lifting roll 15 provided on the outlet side at the center position of the gantry 13.

And the ultra-thin metal foil 36 discharged | emitted out of the vertical looper 10 is the winding machine (not shown) provided in the process equipment delivery side via the looper exit side guide roll 39 and the discharge guide roll 40. , The ultrathin metal foil 36 unwound from the ultrathin metal foil coil 37 can be processed.
At this time, if the ultrathin metal foil 36 meanders to the left (right) side in the traveling direction, the left (right) end position of the ultrathin metal foil 36 is displaced from the reference position to the left (right) side. This is detected by the foil position detection sensor 31, and the turning rolls 26 and 26a turn clockwise (counterclockwise) by an angle proportional to the amount of displacement. As a result, the traveling direction of the ultrathin metal foil 36 also changes in a clockwise direction (counterclockwise) in plan view, and the meandering of the ultrathin metal foil 36 is corrected.

As shown in FIG. 3A, following the processing of the ultrathin metal foil 36, the non-thin metal unrolled from the non-thin metal foil coil 41 mounted on the second unwinding reel 33. When processing the foil 42, the operation of the first unwinding reel 32 and the processing equipment is stopped. Then, the ultrathin metal foil 36 is cut immediately upstream of the welding machine 34, and the end portion of the ultrathin metal foil 36 that has been pre-processed and the non-thin metal mounted on the second unwinding reel 33. The tip of the non-ultra thin metal foil 42 unwound from the metal foil coil 41 is welded by a welding machine 34.

After welding is completed, the non-ultra thin metal foil 42 is fed into the vertical looper 10, and the ultra thin metal foil 36 in the vertical looper 10 is gradually replaced with the non-ultra thin metal foil 42. Then, as shown in FIG. 3B, when it is confirmed that the connecting portion 43 of the ultrathin metal foil 36 and the non-ultra thin metal foil 42 has been discharged out of the vertical looper 10, FIG. As shown in C), the base 13 is lowered and separated from the fixed roll 12, that is, the lift rolls 15 are arranged below the fixed base 17, and the non-thin metal After the foil 42 has been zigzag-engaged with the fixed rolls 12 and the lifting rolls 15, the sheet passing is started. Thereby, the non-ultra thin metal foil 42 can be stored in the vertical looper 10. At this time, if meandering occurs in the non-ultra-thin metal foil 42, it is detected by the foil position detection sensor 31, and the revolving rolls 26 and 26a are swung in the same manner as in the case of the ultra-thin metal foil 36. The meandering of the foil 42 is corrected.

As shown in FIG. 4A, following the processing of the non-ultra thin metal foil 42, the non-ultra thin metal coil 44 unwound from the non-ultra thin metal foil coil 44 attached to the first unwinding reel 32 is used. When processing the metal foil 45, the operation of the second unwinding reel 33 is stopped, and at the same time, the gantry 13 is gradually raised, and the non-ultra-thin metal foil 42 stored in the vertical looper 10 is Sends out according to the processing speed of the processing equipment (winding speed of the winder). On the other hand, the non-ultra-thin metal foil 42 is cut immediately upstream of the welding machine 34, and the non-ultra-thin is attached to the end portion of the non-ultra-thin metal foil 42 and the first unwinding reel 32 that have been previously processed. A welding machine 34 welds the tip of the non-thin metal foil 45 unwound from the metal foil coil 44 and passed over the second unwinding reel 33. Then, after the welding is completed, the operation of the first unwinding reel 32 is started.

Next, as shown in FIG. 4 (B), the gantry 13 is lowered and separated from the fixed roll 12, that is, each lifting roll 15 is placed below the fixed gantry 17. A non-ultra thin metal foil 45 is passed through each fixed roll 12 and each lifting roll 15 in a zigzag manner. Thereby, the non-ultra thin metal foil 45 can be stored in the vertical looper 10. At this time, if meandering occurs in the non-ultra-thin metal foil 45, the swirling rolls 26 and 26a are swirled as in the case of the ultra-thin metal foil 36, and the meandering of the non-thin metal foil 45 is corrected. .

When the processing of the ultrathin metal foil 47 unwound from the ultrathin metal foil coil 46 attached to the second unwinding reel 33 is performed following the processing of the non-thin metal foil 45, the first At the same time as the operation of the unwinding reel 32 is stopped, the gantry 13 is gradually raised, and the non-thin metal foil 45 stored in the vertical looper 10 is sent out in accordance with the processing speed of the processing equipment. On the other hand, the non-thin metal foil 45 is cut immediately upstream of the welding machine 34 and the ultra-thin metal attached to the end portion of the non-thin metal foil 45 and the second unwinding reel 33 that have been processed in advance. The tip of the ultrathin metal foil 47 unwound from the foil coil 46 is welded by a welding machine 34. And as shown to FIG. 5 (A), when the raising / lowering roll 15 latches the non-ultra-thin metal foil 45 on each fixed roll 12 and each raising / lowering roll 15, and passes through in a zigzag state, it is set. The operation of the processing equipment is stopped when it moves to the upper end position.

Next, as shown in FIG. 5 (B), the lift 13 is inserted into the gap B between the fixed rolls 12, that is, the mount 13 is moved until the mount 13 reaches the closest position to the fixed mount 17. Move (rise). At this time, sagging of the non-ultra-thin metal foil 45 occurs in the vertical looper 10, so that it is non-ultra thin by a bridle roll (not shown) installed on the upstream side of the winder provided in the processing facility. The metal foil 45 is advanced and wound by a winder. Then, the ultrathin metal foil 47 is fed into the vertical looper 10 by repeating the forward movement of the non-thin metal foil 45 by the bridle roll and the winding of the non-thin metal foil 45 by the winder. It is.
Then, when it is confirmed that the slack of the non-ultra thin metal foil 45 has disappeared, the operation of the processing equipment and the second unwinding reel 33 is started. Thereby, as shown in FIG.5 (C), the process of the ultra-thin metal foil 47 is started.
