BACKGROUND OF THE INVENTION
The present invention relates to a conveying and laminating apparatus and a conveying and laminating method for a wound strip.
[0002]
[Prior art]
When connecting and laminating a plurality of coils wound with a strip-shaped metal strip, the inner end of the coil is joined with the inner end, the outer end is joined with the outer end, and the metal strip on the inner end side is connected to the inner end portion. The metal strip on the outer end side needs to be wound around the outer end portion.
At this time, since the coil has no winding shaft at the inner end, it is difficult to wind the coil on the inner end portion. For this reason, in such a case, for example, the turntable on which the coil is placed is rotated, and the metal strip is manually wound around the inner end portion, or the metal strip is fed onto the turntable. A guide for determining the position is provided, and a drive feed roll for feeding the metal strip to the inner end portion of the coil in accordance with the rotation of the turntable is disposed in the vicinity.

Hereinafter, an embodiment according to the transport laminating apparatus and the transport laminating method of the present invention will be described in detail with reference to FIGS.
The conveying and laminating apparatus 1 sequentially conveys the coil C having a hollow portion at the winding center, in which a strip-shaped metal strip TM is wound in a predetermined direction, and the inner end and inner end or the outer end and outer end of the coil C are connected to each other. As shown in FIG. 1, it is provided with a conveyor 2, a reversing machine 3, a supply table 4, a welding machine 5, a take-up table 6, and a control device 7. A supplier 8 is formed.
[0008]
The transporter 2 transports the coil C while holding the inner and outer ends of the coil C, and is placed on a portal frame 9 arranged in parallel to the longitudinal direction. The transfer machine 2 includes a moving base 2a that moves in the left-right direction in FIG. 1 on a rail 9a provided on a frame 9, a power cylinder 2b that is controlled by an inverter, three ball bush guides 2c, and a vacuum pad that adsorbs a coil C. 2d. An inverter motor (not shown) is attached to the movable table 2a, and is driven by being engaged with a chain (not shown) that spans a sprocket attached to the rotating shaft of the motor over the upper portion of the frame 9. At this time, the moving position of the moving table 2a is controlled with an accuracy of ± 2 to 3 mm by a limit switch and a proximity switch (not shown). The vacuum pad 2d has a plurality of suction holes (not shown) opened on the lower surface, and is connected to a suction device (not shown) to attract the coil C by negative pressure. Further, as shown in FIG. 5, the vacuum pad 2d has four cylinders 2e and 2f for holding the inner end and the outer end of the coil C at positions corresponding to the inner end side and the outer end side of the coil C, respectively. Has been. Here, the four cylinders 2e arranged at the inner end of the coil C move in the diameter increasing direction, and the four cylinders 2f arranged at the outer end of the coil C move in the diameter reducing direction, respectively. Hold the edge and the outer edge.
[0009]
The reversing machine 3 reverses every other coil C that is conveyed to change the winding direction, and has a lift table 3a and a vacuum pad 3b for temporarily placing the coil C. The lift table 3a is supported by the base 3c so as to be lifted and lowered by the cylinder 3d. The vacuum pad 3b is attached to the table 3e. As shown in FIGS. 2 and 3, the vacuum pad 3b is rotated by 180 degrees about a shaft 3g connected to the rotating shaft of the inverter motor 3f. The rotation is stopped by a proximity switch and an end stopper (not shown). Moreover, the vacuum pad 3b is comprised similarly to the vacuum pad 2d, and adsorb | sucks the coil C with a negative pressure.
[0010]
The supply table 4 is a first placing means for placing the coil C rotatably in a horizontal plane, and includes a scale 4a, a turntable 4b, and a positioning device 40 as shown in FIG. The scale 4a is a platform scale for measuring the weight of the coil C. The turntable 4b is a non-driven table on which the coil C is placed, and rotates with a slight force when the metal strip TM is pulled out from the coil C. Therefore, the metal strip TM can be easily pulled out.
[0011]
Further, the positioning device 40 centers the coil C on the turntable 4b. As shown in FIGS. 4 and 5, the positioning device 40 is provided with a centering roll 43 at the lower end of the arm 42 attached to each of the three columns 41 arranged in the vertical direction on the outer periphery of the turntable 4b. Yes. The three struts 41 are connected by three links 44 that extend radially around the rotation center of the turntable 4 b, and an air cylinder 45 is attached to the other end of the link 44. Therefore, when the positioning device 40 pushes the three columns 41 through the links 44 by the air cylinder 45, the three centering rolls 43 press the side surfaces of the coil C, and the position of the coil C on the turntable 4b is determined. Center.
[0012]
The welder 5 connects the inner end and the inner end of the coil C or the outer end and the outer end by welding. For example, a TIG welder is used. As shown in FIG. 5, the welding machine 5 has a net-clad guide table 5a. The guide table 5a smoothly guides the movement of the metal strip TM of each coil C during forward and reverse rotation of the winding table 6, and has a structure having a predetermined height and a friction surface. And the guide table 5a is arrange | positioned in the up-down direction substantially middle of the welding machine 5, and can be pushed in and stored in the arrow direction. Here, the welding machine 5 has a restriction arm 10. As shown in FIG. 5, the restriction arm 10 is provided on the support table 5 b of the welding machine 5 and includes a turning shaft 10 a and an arc-shaped restriction plate 10 b. When not in use, the regulation arm 10 is swung and accommodated on the support table 5b side so as not to interfere with the transporter 2, and the height of the coil C stacked on the pallet 6a of the take-up table 6 described later. It can be moved up and down in accordance with.
[0013]
The winding table 6 is a second mounting means on which the coil C is mounted, rotates in the horizontal plane, and can adjust the position in the two-dimensional direction in the horizontal plane. As shown in FIG. 4, the winding table 6 includes a pallet 6a on which the coils C are stacked, an XY table 6b that supports the pallet 6a in a two-dimensional direction in a horizontal plane, and a powder clutch. An inverter motor 6c for reverse rotation is provided, and the normal rotation angle and the reverse rotation angle are determined by controlling the normal rotation time of the pallet 6a with a timer of a sequencer. Here, the coil C is, for example, a copper strip having a thickness of 0.2 mm and a width of 20 mm wound around an inner diameter of 400 mm and an outer diameter of 1200 mm, and has a weight of about 160 kg. For this reason, if 10 stages of such coils are stacked, it becomes 1600 kg and the rotation angle control becomes difficult, so that the pallet 6a can control the rotation angle more appropriately with the coil C having a large weight placed thereon. The rotation angle may be controlled using an AC servo motor, controller, sequencer, or the like.
[0014]
The control device 7 is for automatically operating the transport laminating device 1, and for example, a sequencer or the like is used.
The supplier 8 is a place where the laminated coil C cut by a slitter is transported and stocked by a lift or the like. An XY table may be arranged in the supplied 8 so that the position of the X direction parallel to the transport direction and the Y direction perpendicular to the transport direction can be adjusted with respect to the vacuum pad 2d of the transport machine 2. Good.
[0015]
The transport laminating apparatus 1 of the present invention is configured as described above, and connects the inner end and the inner end of the coil C or the outer end and the outer end while sequentially transporting the plurality of coils C by the transport laminating method described below. And pile up.
Here, the plurality of coils C stacked on the supplier 8 are wound with the metal strip TM in the clockwise direction from the center toward the outside. In the following description, this winding direction is called right-handed and vice versa. The winding direction is called left-handed.
[0016]
In the transport lamination method of the present invention, first, the outermost ends of the metal strips TM are connected to the uppermost first coil C1 of the plurality of coils C previously stacked on the supplier 8 and the second coil C2 therebelow. Connect and stack.
That is, first, the moving platform 2a of the transporter 2 is moved along the rail 9a to the supplier 8.
[0017]
Then, the vacuum pad 2d is lowered by the power cylinder 2b and the uppermost first coil C1 is adsorbed from the plurality of coils C previously stacked on the supplier 8. Here, the outer ends of the coils C stacked on the supplier 8 are temporarily fixed with tape or the like.
Next, the vacuum pad 2d is raised to the position shown in FIG. 1 by the power cylinder 2b, and the sucked first coil C1 (see FIG. 7) is conveyed to the supply table 4 and weighed by the scale 4a. At this time, the transporter 2 transports the first coil C1 while holding the inner end and the outer end by the four cylinders 2e and 2f, respectively.
[0018]
Next, the weighed first coil C1 is lowered onto the pallet 6a of the winding table 6 by the conveyor 2 and the conveyor 2 is returned to the supplier 8. At this time, as shown in FIGS. 6 and 7, the first coil C1 is placed on the pallet 6a via the cardboard 6d, the guide plate PG, and the spacer 6e.
Here, the guide plate PG is, for example, a plate made of vinyl chloride, polypropylene or the like having a thickness of about 0.7 mm, and is formed in an arc shape as shown in FIG. 13, and the inner peripheral side is between the corrugated cardboard 6d and the spacer 6e. Placed in. If four guide plates PG are arranged under the first coil C1, the flange extends in the circumferential direction on the outer peripheral side of the first coil C1, and the edge of the metal strip TM of the coil falls when winding the outer periphery. Instead, it is slid so that it can be smoothly wound around the outer periphery of the first coil C1. Therefore, it is desirable to use a material with a small friction with the metal strip TM for the guide plate PG.
[0019]
Thereafter, the second coil C2 (see FIG. 7) is sucked by the vacuum pad 2d in the same manner by the transporting machine 2 returned to the supplier 8 and transported to the lift table 3a of the reversing machine 3 for mounting.
Next, the vacuum pad 3b is rotated 180 degrees from the state shown in FIG. 1, and the lift table 3a is raised to attract the second coil C2. When the lift table 3a is lowered, the vacuum pad 3b is rotated 180 degrees in the reverse direction and returned to the position shown in FIG. 1 again to release the suction of the second coil C2. As a result, the second coil C2 is left-handed, with the winding direction of the metal strip TM being different from the first coil C1.
[0020]
Here, the plurality of coils C of the supplier 8 are used in a left-handed manner with the even-numbered coils C being inverted, and the odd-numbered coils are used in a right-handed state without being inverted.
Next, the second coil C2 is transported to the supply table 4 by the transporter 2, and is weighed by the scale 4a. At this time, the transport machine 2 stands by above the supply table 4. The second coil C2 is centered on the turntable 4b by the three centering rolls 43 of the positioning device 40.
[0021]
Thereafter, the metal strips TM on the outer ends of the first coil C1 on the winding table 6 and the second coil C2 on the supply table 4 are respectively pulled out to the position of the welding machine 5 and connected by welding.
Next, the outer end side of the connected metal strip TM is placed on the guide table 5a, and the guide table 5a is pulled out to the near side as shown in FIG.
[0022]
Next, as a preparation for starting the outer end winding, the winding table 6 is manually turned to take up the slack of the metal strip TM pulled out to the position of the welding machine 5, and the metal strip TM is wound around the first coil C1.
Thereafter, the second coil C2 on the supply table 4 is adsorbed by the vacuum pad 2d, and the inner end and the outer end of the second coil C2 are pressed by the four cylinders 2e and 2f.
[0023]
Next, in this state, winding of the outer circumference of the metal strip TM to the outer end of the first coil C1 is started. This winding start is executed by pressing a start button (not shown) provided in the control device 7.
When the outer periphery winding is started, the vacuum pad 2d that adsorbs the second coil C2 of the transporter 2 rises, the moving table 2a moves to the winding table 6 side, and the winding table 6 is corrected by the inverter motor 6c. Start rolling.
[0024]
As a result, the welded metal strip TM slides on the guide table 5a, and the rotation of the winding table 6 causes the metal strip TM to move on the four guide plates PG disposed below the first coil C1. Winding around the outer periphery of the first coil C1 while sliding.
When the movable table 2a stops just above the winding table 6, the forward rotation of the winding table 6 stops, and the outer periphery winding of the metal strip TM to the outer end of the first coil C1 ends.
[0025]
Next, the vacuum pad 2d of the transfer device 2 is lowered, and the descent stops with a gap of 1 to 5 mm between the second coil C2 and the first coil C1. At this time, since the metal strip TM is slackened as the vacuum pad 2d is lowered, the winding table 6 is rotated little by little by hand to wind the metal strip TM on the outer end side of the first coil C1.
Thereafter, four spacer plates PS are inserted at 90 ° intervals in the radial direction between the first coil C1 and the second coil C2 using the gap, and the metal strip TM is disposed outside the first coil C1. The position of the turn part that moves to the second coil C2 is determined. The spacer plate PS is a plate made of vinyl chloride, polypropylene, or the like having a long predetermined thickness (for example, 1 mm) protruding about 50 mm from the inner diameter side and the outer diameter side of the first coil C1.
[0026]
Next, in the turn portion, the step of the metal strip TM caused by a slight difference in the outer diameter between the first coil C1 and the second coil C2 or a misalignment of the center between the two coils cannot be made. The winding table 6 is moved in the XY directions to adjust the position of the first coil C1 with respect to the second coil C2.
In this state, a sponge belt (not shown) is disposed inside the turn portion where the metal strip TM moves to the second coil C2 outside the first coil C1, and the winding table 6 is again connected to the inverter having the powder clutch. Driven by the motor 6c, the metal strip TM is wound up. In parallel with this tightening, the vacuum pad 2d of the conveyor 2 is lowered, the second coil C2 is superimposed on the first coil C1, and the rotation of the winding table 6 is stopped.
[0027]
At this time, the first coil C1 and the second coil C2 whose outer ends of the metal strip TM are welded to each other are moved and stacked as shown in FIGS. 8 (a) to 8 (d). Here, the symbol PW in the figure indicates a welded portion.
Thereafter, the press of the inner end and the outer end of the second coil C2 by the four cylinders 2e and 2f of the transport device 2 is released, the vacuum pad 2d is raised, and then the transport device 2 is moved to the supplier 8. .
[0028]
As described above, the first coil C1 and the second coil C2 are laminated by connecting the outer ends of the metal strip TM, and the first coil C1 and the second coil C2 are connected as a long coil. At this time, the winding direction of the metal strip TM is clockwise in the first coil C1, and the winding direction of the second coil C2 is different from that in the left winding. For this reason, when the metal strip TM is pulled out from the inner end of the second coil C2, the metal strip TM can be continuously fed out to the inner end of the first coil C1 through the outer end of the second coil C2.
[0029]
The outer ends of the metal strips TM of the first coil C1 and the second coil C2 are connected to each other, and the guide plate PG is removed when the lamination is completed.
When the outer ends of the first coil C1 and the second coil C2 are connected as described above, the inner ends of the second coil C2 and the third coil C3 are connected to each other as follows. A third coil C3 is laminated on C2.
[0030]
First, the third coil C3 (see FIG. 7) is sucked by the vacuum pad 2d and transported to the supply table 4 in the same manner as described above by the transporter 2 returned to the supplier 8 and weighed by the scale 4a. At this time, the transport machine 2 stands by above the supply table 4. The position of the third coil C3 on the turntable 4b is centered by the positioning device 40.
[0031]
Next, the metal strip TM on the inner end side of the second coil C2 on the winding table 6 and the third coil C3 on the supply table 4 is pulled out to the position of the welding machine 5 and connected by welding.
Next, the inner end side of the connected metal strip TM is placed on the guide table 5a.
After that, as shown in FIG. 5, as a preparation for starting the inner end winding, a frustoconical winding guide 6f is disposed in the hollow portion that becomes the winding center of the second coil C2, and the regulating arm 10 is turned. It is made to project above the second coil C2. Further, in order to remove the slack of the metal strip TM drawn to the position of the welding machine 5, the winding table 6 is turned by hand to wind the metal strip TM around the second coil C2. Since this winding operation is only for removing the slack of the metal strip TM, a delicate adjustment of the winding length is unnecessary.
[0032]
Here, the winding guide 6f is formed by winding up sheet-shaped plastic such as vinyl chloride or polypropylene into a truncated cone shape. The upper and lower portions are opened, and the lower diameter is set smaller than the inner diameter of the coil C. Has been.
Next, the third coil C3 on the supply table 4 is attracted by the vacuum pad 2d of the transporter 2, and the inner end and the outer end of the third coil C3 are pressed by the four cylinders 2e and 2f.
[0033]
In this state, winding of the inner circumference of the metal strip TM to the inner end of the second coil C2 is started. This winding start is executed by pressing a start button (not shown) provided in the control device 7.
When the inner circumference winding is started, the vacuum pad 2d of the transporter 2 that has attracted the third coil C3 is raised, the moving table 2a moves to the winding table 6 side, and the winding table 6 has a powder clutch. The forward / reverse rotation is repeated several times while performing forward rotation about 360 degrees and reverse rotation about 90 degrees by the inverter motor 6c (see FIGS. 9 and 10).
[0034]
At this time, although the guide table 5a is pulled out, it is located below, so that the attracted third coil C3 and the guide table 5a do not interfere even if the transporter 2 moves.
In addition, as shown in FIG. 11A, the second coil C2 has a metal strip TM extending toward the supply table 4 before winding. In this state, as shown in FIG. 11B, when the winding table 6 is rotated approximately 360 degrees in the counterclockwise direction indicated by the arrow, the edge of the metal strip TM slides on the guide table 5a, It will be in the state wound up by the winding guide 6f. At this time, since the winding guide 6f has a truncated cone shape, the metal strip TM to be wound later is wound inward. In particular, this action is conspicuous when the take-up table 6 is intended to increase the take-up speed by, for example, normal rotation by 720 degrees and reverse rotation by 90 to 180 degrees.
[0035]
Thereafter, as shown in FIG. 11C, when the winding table 6 is rotated approximately 90 degrees in the clockwise direction indicated by the arrow, the metal strip TM is prevented from protruding outward in the radial direction due to the reverse rotation. It is rewound to the inner end side of the second coil C2 while being regulated by 10b.
As a result of the reversal of the winding table 6 by about 90 degrees, the metal strip TM corresponding to a length corresponding to about 3/4 rotations is struck between the winding guide 6f and the hollow portion of the second coil C2.
[0036]
At this time, the winding guide 6f has a truncated cone shape, and the metal strip TM wound later is wound more inside. For this reason, all of the metal strip TM to be rewound is rewound inside the second coil C2 in the same order as when it was wound around the winding guide 6f, and the order does not move back and forth. Can be wound or rewound by rotating at a high speed.
[0037]
On the other hand, when the winding guide 6f has a cylindrical shape with the same upper and lower diameters, when the winding guide 6f tries to wind up 360 degrees or more, the order of the metal strips TM is changed when the winding guide 6f is wound. When rewinding to the second coil C2 due to reverse rotation, the winding order may be reversed. In such a state, when the inner ends and inner ends of the plurality of coils C and the outer ends and the outer ends are connected to form a long coil, the metal strip TM cannot be continuously fed out.
[0038]
When the movable table 2a stops immediately above the winding table 6, the forward / reverse rotation of the winding table 6 stops, and the inner circumference winding of the metal strip TM to the inner end of the second coil C2 ends.
Next, the regulating arm 10 is swung to the support table 5b side and stored so as not to interfere with the transporting device 2.
[0039]
Next, after the vacuum pad 2d of the transfer device 2 is lowered and the lowering is stopped with a gap of 1 to 5 mm between the third coil C3 and the second coil C2, the winding guide 6f is moved from the second coil C2. Take out. At this time, since the metal strip TM is loosened as the vacuum pad 2d is lowered, the winding table 6 is rotated little by little by hand to wind the metal strip TM on the inner end side of the second coil C2.
[0040]
Thereafter, as shown in FIG. 6, four spacer plates PS are inserted between the second coil C2 and the third computer C3 at intervals of 90 degrees in the radial direction, so that the spacer plate is placed on the second coil C2. Place PS. Further, when the outer ends of the metal strips TM in the third coil C3 and the fourth coil C4 are connected and stacked, the guide plate PG is supported so that the metal strip TM is smoothly wound around the outer periphery of the third coil C3. Is inserted in advance between the second coil C2 and the third coil C3.
[0041]
Next, the position of the turn portion at which the metal strip TM moves from the second coil C2 to the third coil C3 is determined.
Next, in the turn portion, winding is performed so that there is no level difference in the metal strip TM due to a slight difference in inner diameter between the second coil C2 and the third coil C3, a center position shift between the two coils, or the like. The table 6 is moved in the X and Y directions to adjust the position of the second coil C2 with respect to the third coil C3.
[0042]
In this state, the winding table 6 is again rotated by hand to remove the slack of the metal strip TM on the inner end side.
Thereafter, the vacuum pad 2d of the transfer machine 2 is lowered, and the third coil C3 is overlaid on the second coil C2. At this time, the second coil C2 and the third coil C3, whose inner ends of the metal strip TM are welded to each other, are moved and stacked as shown in FIGS. 12 (a) to 12 (d). Here, the symbol PW in the figure indicates a welded portion.
[0043]
Next, after pressing the inner and outer ends of the third coil C3 by the four cylinders 2e and 2f of the transport machine 2 and lifting the vacuum pad 2d, the transport machine 2 is moved to the supplier 8 .
As described above, the second coil C2 and the third coil C3 are laminated with the inner ends of the metal strips TM connected to each other, and the first coil C1 to the third coil C3 are connected as a long coil. At this time, the first coil C1 and the third coil C3 are wound clockwise in the winding direction of the metal strip TM, and the second coil C2 is different in winding direction from the left-handed winding. Therefore, when the metal strip TM is pulled out from the outer end of the third coil C3, the inner end of the second coil C2, the outer end and outer end of the second coil C2, and the inner end of the first coil C1 and the metal strip TM are continuously connected. Can be paid out.
[0044]
Similarly, as shown in FIG. 14, a long coil that can be continuously drawn out is obtained by connecting and stacking the third coil C3 and the coil C that is equal to or lower than the fourth coil C4. At this time, the metal strip TM is connected at the outer periphery when the even-numbered coil is laminated on the odd-numbered coil as in the case where the fourth coil C4 is laminated on the third coil C3, and the even-numbered coil is odd-numbered. When the coils are stacked, they are connected on the inner circumference. Therefore, the guide plate PG is disposed under the odd numbered coils as shown in FIG.
[0045]
Further, as shown in FIG. 14, when the first coil C1 and the second coil C2 are connected at the outer periphery, the multi-layered coil has the metal strip TM drawn upward from the uppermost stage. As for 1 coil C1, metal strip TM is pulled out from the outside. For this reason, in the first coil C1, the inner metal strip TM is subjected to stress pushed inward by the outer metal strip TM pulled upward, and the last remaining inner metal strip TM is prevented from being blown out. This makes it possible to safely perform the pull-out operation without taking any special measures.
[0046]
Here, in the above-described embodiment, the case of a coil in which a metal strip is wound as a wound strip has been described. However, the transport laminating apparatus and the transport laminating method of the present invention use an adhesive device instead of a welding machine. For example, it can be used to make a long tape by connecting and stacking the inner end and inner end, and the outer end and outer end of a wound strip of paper tape or plastic tape. Needless to say.
[0047]
【The invention's effect】
According to invention of Claim 1, 3, it is used when connecting the inner end and inner end of a plurality of wound strips, and connecting the outer end and outer end, respectively, into a long body, and is safe and inexpensive. A laminating apparatus and a transport laminating method can be provided. In particular, according to the first and third aspects of the invention, when connecting or laminating a plurality of wound strips, the operator does not have to put his hand between the wound strips, which is extremely safe.
