Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility for cutting a sent strip into a plurality of strips along a longitudinal direction to form a plurality of narrow slit strips and rewinding the slit strips. The present invention relates to a guide device for slit strips, which guides slit slit strips to a winding device in a state where they are separated from each other.

[0002]

2. Description of the Related Art Conventionally, strips that have been sequentially sent are
A plurality of slit strips formed by cutting with a slitter along the longitudinal direction is disclosed, for example, in Japanese Patent Laid-Open No. 51-10926.
As described in Japanese Patent Publication No. 3, a slit reel is wound around a tension reel while being separately guided by a facility having a free loop.

However, the slit strip guiding device as described above requires a large space for providing the free loop. In addition, it is necessary to apply rearward tension with a tension pad or bridle roll to remove slack when winding on a tension reel, but it is difficult to apply a large rearward tension, so the winding tension by the tension reel. I have no choice but to lower
There is a problem that the coil may be deformed.

Therefore, conventionally, the tension reel is guided without tensioning the free loop. At this time, the divided slit strips need to be guided so as not to overlap each other on the tension reel, but in the prior art, as shown in FIG. 5, for example, a slitter cuts the fed strips. Between the two slit strips 1 formed by forming the donut ring 30 with its axis oriented in the plate width direction.
The slit strip 1 is guided to the tension reel 2 while being controlled so that the gap between the two slit strips 1 becomes constant.

Further, as shown in FIG. 6, two or more slit strips 1 formed by cutting a strip with a slitter are provided with a pair of pinch rolls 31 and are sandwiched by the pinch rolls 31 to be tension reels. 2 so as to guide the respective pinch rolls 31 in the direction in which the slit strips 1 are separated from each other (outward in the plate width direction), as indicated by P1 and P2 in FIG. They are guided in the state of being separated by.

Further, as described in JP-A-1-205818, the slit strip is pressed by a pair of conical separator rolls each having a smaller diameter toward the adjoining direction of two slit strips. The slit strip is guided to the winding device.

[0007]

However, in the above-mentioned slit strip guide device, in the system using the donut ring 30, the winding speed of the slit strip 1 by the tension reel 2 is 100 mp.
When operating at a high speed of m or more, the friction coefficient of the contact portion between the not-shown roll and the slit strip 1 becomes small, and meandering occurs in the slit strip 1 in the direction of the board field.
There is a problem in that high-speed operation cannot be performed because problems such as getting up to zero and damaging the widthwise end of the slit strip 1 due to collision with the side surface of the donut ring 30 are likely to occur.

Further, even in the system in which the slit strip is pressed down and guided by the pinch roll 31, since the lubricating liquid such as oil adheres to the surface of the slit strip 1, a contact portion between the slit strip 1 and the pinch roll 31 is formed. Has a smaller friction coefficient, and the guided slit strip 1 tends to slip in the plate width direction. When the slip occurs, the widthwise inner ends of the slit strips 1 divided by the meandering by the slip are separated from each other. There is the problem of collisions and overlapping.

Also in the method disclosed in Japanese Patent Laid-Open No. 1-205818, slip in the slit strip 1 is apt to occur in the width direction, and in particular, the diameter of the two slit strips 1 becomes small in the opposing direction. Therefore, slips are likely to occur in the overlapping direction, and similarly to the pinch roll 31, there is a problem that the widthwise end portions of the divided slit strips 1 collide with each other or overlap each other.

The present invention has been made in view of the above-mentioned problems, and guides a slit strip which can be guided to a tension reel while a plurality of divided slit strips are separated from each other. The purpose is to provide a device.

[0011]

To achieve the above object, the slitted strip guiding device of the present invention comprises:
In a guide device in which continuous slits are sequentially cut into multiple strips along the longitudinal direction and each slit strip is guided by a separator roll and wound on a tension reel, the separator rolls are individually moved in the vertical direction. It is characterized in that it is provided with a roll up-and-down movement driving means for moving to

Further, in a guide device in which each slit strip formed by sequentially cutting a continuous strip into multiple strips along the longitudinal direction is guided by a separator roll and wound around a tension reel, From the gap measuring means, a roll shaft inclination driving means for rotating and inclining the axis line of up and down, a gap measuring means for measuring a gap in the plate width direction between each of the separated slit strips on the downstream side of the separator roll. And a controller for driving the roll shaft tilt drive means in response to a signal corresponding to the gap amount to tilt each separator roll by a predetermined angle.

Further, in a guide device in which each of the slit strips formed by cutting a continuous strip into multiple strips along the longitudinal direction is guided by a separator roll and wound on a tension reel, each separator roll is Between the roll vertical movement drive means for individually moving in the vertical direction, the roll shaft tilt drive means for rotating and tilting the axis of each separator roll in the vertical direction, and between the separated slit strips on the downstream side of the separator roll. A gap measuring means for measuring the gap in the plate width direction, and the roll vertical movement driving means and the roll shaft inclination driving means are driven according to a signal corresponding to the gap amount from the gap measuring means to drive each separator roll by a predetermined amount. The controller is characterized in that it is provided with a controller that moves up and down only and tilts by a predetermined angle.

[0014]

The roll vertical movement driving means is driven to move each separator roll upward to press each slit strip from the lower side, and the height of each separator roll is made different. This prevents the pass lines of the slit strips from overlapping in the plate width direction,
Even if each slit strip slips on the separator roll and meanders in the plate width direction, it is prevented from colliding with or overlapping with the adjacent slit strips.

Further, when the axis of the separator roll is rotated and tilted, a force F in the plate width direction corresponding to the tilt angle θ is contacted with the separator roll in the tilt direction of the axis as shown in FIG. Is applied to the slit strip via.
As a result, if the gap between the adjacent slit strips becomes narrower than the target value, the slit rolls are inclined by a predetermined amount so that the slit strips are inclined to the opposite sides. Make the gap between them wide.

When the gap between the adjacent slit strips becomes wider than the target value, the separator rolls are inclined to the slit strips by a predetermined amount in the gap direction, and the slits are applied to the respective slit strips. The gap is reduced by a predetermined amount by reducing the force outward in the plate width direction or applying a force inward in the plate width direction. Further, the separator roll is moved up and down without changing the inclination angle to change the pressing force (P in FIG. 4) exerted on the slit strip by the separator roll, so that the slit strip is applied in the plate width direction. The external force may be changed to adjust the gap between the strips.

[0017]

Embodiments of the present invention will be described with reference to the drawings. First, the structure will be described. As shown in FIGS. 1 and 2, a strip 3 formed by a rolling operation or the like (not shown) is wound around a payoff reel 5. A slitter 4 is arranged on the downstream side of the payoff reel 5, and the strip 1 cut by the slitter 4 is transferred to the tension reel 2 by a pair of separator rolls 6 and a deroll 7 arranged on the downstream side of the slitter 4. You will be guided.

A gap measuring sensor (gap measuring means) for measuring the gap between the two slit strips 1 formed is provided in the middle of the pass line between the pair of separator rolls 6 and the deflour 7. Emitter 8 and receiver 9
Are arranged with their axes vertically opposed to each other. The gap measuring sensor consisting of the light projector 8 and the light receiver 9 is connected to the controller 10 and is connected to the two slit strips 1
A signal corresponding to the gap between them is supplied to the controller 10.

The pair of separator rolls 6 are respectively provided with roll vertical movement drive means and roll shaft tilt drive means. That is, as shown in FIG. 3, one end portion of the separator roll 6, that is, the outer end side in the plate width direction, is rotatably connected to the installation base 14 in the vertical direction. Further, on the other end of the separator roll 6, that is, on the inner end side in the plate width direction, there is arranged a tilting cylinder device 13 as a roll up-and-down motion driving device with the shaft up and down, and a rod of the cylinder device 13. 13a is the separator roll 6
The other end of the cylinder device 13 is swingably connected, and the lower end of the cylinder device 13 is swingably fixed to the installation table 14.

On the lower surface of the installation table 14, the installation table 14
Up-down movement actuators 15 that are roll up-and-down movement driving means for moving up and down are respectively installed, and the installation table 14 is driven by the actuators 15.
The separator roll 6 can be moved up and down via the. The tilt drive cylinder device 13 and the vertical movement actuator 15 are respectively connected to the controller 10 and can be driven by a drive command from the controller 10.

In the apparatus having the above structure, the strip 3 is unwound from the payoff reel 5, and the unwound strip 3 is sequentially sent to the slitter 4 and cut into two strips along the longitudinal direction. The two slit strips 1 formed by cutting are guided while being pressed by the separator rolls 6 from the lower side, and wound around the tension reel 2 via the deflour 7 to form slit coils. In addition, the deflor 7 is the tension reel 2
The slit strips 1 are pressed from below with a predetermined force in order to apply a predetermined tension to each slit strip 1 before being wound up.

By driving the actuators 15 for vertical movement, the installation bases 14 on which the separator rolls 6 are installed are individually moved upward by a predetermined amount h _{1 or} h ₂ . At this time, the one installation base 14 is moved so as to be higher than the other installation base 14 by a predetermined height (h ₂ −h ₁ ), and the heights of the two separator rolls 6 are made different.

As a result, the slitter 2 cut the 2
Since the heights of the pass lines of the slit strips 1 of the strips are different and each of the divided slip strips 1 slips in the width direction and meanders, it does not overlap with the pass line of another adjacent slip strip 1. Even if the two strips of slip strip 1 slip and meander, they do not collide or overlap.

When the slit strip 6 is guided to the tension reel 2 by the separator roll 6 as described above, the slit strip 1 is divided into two strips.
The gap between them is measured by a gap measuring sensor composed of a light emitter 8 and a light receiver 9 facing each other vertically, and a gap signal corresponding to the gap is supplied to the controller 10 at any time. If the gap between the slit strips 1 is smaller than the target value based on the gap signal, that is, the controller 10 determines that the distances Cd and Cw from the central portion of each slit strip 1 in the widthwise inner end direction are individual targets. If it is smaller than the value, the tilting drive cylinders 13 connected to the respective installation tables 15 are respectively driven to extend the rods 13a by a predetermined amount and rotate the axis of each separator roll 6 toward the plate width direction outer side. Tilt at a specified angle.

Then, as shown in FIG. 4, the external force F outward in the width direction of the portion of the slip strip 1 in contact with the separator roll 6 increases by an amount corresponding to the inclination angle θ of the separator roll 6. The slit strip 1 is likely to be displaced outward in the width direction, and the gap is widened. Also,
When the controller 10 recognizes that the gap between the slit strips 1 is wider than the target value, the controller 10 drives the tilt drive cylinder 13 to return the rods 13a by a predetermined amount to move the axis of each separator roll 6. The inclination angle θ from the horizontal direction is reduced to reduce the external force F, so that the slit strip 1 is easily displaced inward in the width direction and the gap is narrowed.

As described above, the controller 10 performs the above-described processing as needed to perform feedback control so that the gap between the two slit strips 1 is maintained at a predetermined target value. Note that, as can be seen from FIG. 4, the external force F changes even if the pressing force P applied to the slit split 1 by the separator roll 6 is changed. Therefore, by driving the actuator 15 for vertical movement, each separator roll 6 is moved up and down. Alternatively, the external force F may be controlled by performing a feedback control of the pressing force P applied to each slit split 1 to control the external force F.

Actually, the height of one separator roll 6 is set higher than the pass line of the strip 4 before being cut by the slitter 4 by (h ₁ =) 10 to 100 mm, and the other separator roll 6 is set to the above. One separator roll 6
(H ₂ −h ₁ =) 20 to 50 mm higher than the above, and the axes of the two separator rolls 6 are
The inclination angles θ _{1 and} θ ₂ with respect to the horizontal can be changed within the range of 0.5 to 5 °, and the two slit strips 1 are guided to the tension reel 2 to be wound up under the high speed operation of 300 mpm or more. However, it was confirmed that the formed slit coils were wound on the tension reel 2 with a predetermined tension without overlapping each other.

In the above embodiment, an example in which a slit coil having two strips is formed has been described, but the present invention can also be applied when winding a plurality of strips having three strips or more. Further, in the above embodiment, the axis of each separator roll 6 is inclined only outward in the plate width direction,
The tilt may be made in the opposite direction, that is, inward in the plate width direction.

[0029]

As described above, in the slit strip guide device of the present invention, the gap between the slit strips formed by division is maintained at the target value even under the high speed operation of 300 mpm or more. The tension coil can be guided to the tension reel as it is, so that it is possible to obtain a slit coil which has a predetermined tension on the tension reel and does not overlap.
