[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for transporting a steel sheet.

[0002]

2. Description of the Related Art Conventionally, a heat-insulated steel sheet in which a heat insulating material is attached to a steel sheet is excellent in heat insulation, fire resistance, soundproofing, workability, and the like.
It is molded into an appropriate shape by a molding machine and used as a building material. An apparatus for attaching such a heat-insulating steel sheet, that is, an apparatus for cutting a steel sheet and a heat insulating material into a predetermined length after press-bonding the same, will be described with reference to FIG.

[0003] The heat insulating material attaching apparatus 1 includes a gantry 2, an uncoiler 3 provided on the gantry 2 and supporting a steel sheet (hereinafter, referred to as a coil C) wound into a roll.
A pair of pinch rolls 4, 4 before and after drawing the steel sheet P from the coil C supported by the uncoiler 3, a gauge roll 5 for measuring the length of the steel sheet P drawn through the pinch rolls 4, 4, An adhesive application roll 6 for applying an adhesive to the steel sheet P, and a heater 7 for heating and drying the adhesive applied to the steel sheet P or for preheating the steel sheet P
And a pair of pressure rolls 9 before and after pressing the heat insulating material T onto the steel plate P, and a Pefshire 8 for cutting the heat insulating material T to a predetermined length.
And a Pefslitter 10 for cutting out a protruding portion of the heat insulating material T of a steel plate (hereinafter referred to as a heat insulating steel plate) to which the heat insulating material T is crimped, and a steel plate shear 11 for cutting the heat insulating steel plate to a predetermined length.

[0004] The steel sheet P unwound from the coil C supported by the uncoiler 3 is drawn out by a pinch roll 4, measured in length via a gauge roll 5, and then conveyed downstream. Here, when the heat insulating material T of the adhesive application method is applied, the adhesive is applied to the steel sheet P via the adhesive application roll 6 and sent out to the heater 7.
When the heat-insulating type heat insulating material T is to be applied, the rotating roll 6b is lowered to apply the heat to the heater 7 without applying the adhesive.
To send out. The steel sheet P carried into the heater 7 dries the adhesive in the case of the adhesive bonding method, and preheats the steel sheet P in the case of the heat bonding method. After that, the heat insulating material T cut by the pefshire 8 is attached to the steel sheet P,
Further, the heat-insulating steel plate is formed by being pressed by the pressing roll 9. Next, the steel sheet P is passed through the pef slitter 10.
After cutting the protruding heat insulating material T, the heat insulating material T is cut into a predetermined length by the heat insulating steel plate shear 11 and supplied to a molding machine (not shown).

[0005]

In the heat insulating material attaching apparatus 1 described above, the pinch roll 4 serving as a transfer device for supplying the steel sheet P to the heater 7 is a drive roll rotatably supported on the gantry 2. 4a, and a press roll 4b positioned above the drive roll 4a and rotatably supported at an interval corresponding to the thickness of the steel sheet P. The drive roll 4a is rotated via a drive device (not shown), By feeding the steel sheet P between the holding roll 4b and the driving roll 4a, the steel sheet P is sandwiched and conveyed downstream.

At this time, the driving roll 4a and the holding roll 4
There is no problem if b and the steel plate P contact uniformly and rotate.
Due to the roundness of the driving roll 4a and the holding roll 4b, the parallelism of the axes of the two rolls 4a and 4b, the gap error between the two rolls 4a and 4b, and other various factors, the steel sheet P and the two rolls 4a and 4b become entangled. If they do not contact uniformly, the steel sheet P may meander. When such a meandering of the steel sheet P occurs, the pressing roll 4 with respect to the driving roll 4a is empirically determined.
The mounting position of b must be adjusted by taking many man-hours, and such adjustment work must be performed every time the thickness of the steel plate changes, which makes the work complicated. was there.

[0007] The present invention has been made in view of the above problems, and an object of the present invention is to provide a steel sheet conveying apparatus capable of conveying a steel sheet without meandering.

SUMMARY OF THE INVENTION The present invention comprises a driving roll rotatably supported and a holding roll rotatably supported above the driving roll, which is supported by a driving device. A steel sheet transporting device that rotates the drive roll and transports the steel sheet by sandwiching it between the drive roll and the holding roll.The gap between the holding roll and the drive roll can be adjusted via a gap regulating stopper. In addition to supporting the steel plate, the steel plate is pressed and urged between the steel plate and a driving roll via a spring.

[0009]

The gap regulating stopper is operated to adjust the pressing roll supported by the gap regulating stopper so as to form a set gap with the driving roll. Further, the urging force of the spring against the pressing roll supported by the gap regulating stopper is adjusted.

As a result, even if the thickness of the steel sheet changes, the holding roll is automatically adjusted by being lifted against the urging force of the spring, and the steel sheet is connected to the driving roll via the raised holding roll. Since the sheet is uniformly pressed and conveyed between them, the meandering of the steel sheet can be surely prevented.

By setting to mm, it became possible to convey a steel sheet having a thickness of 0.25 to 1.25 mm almost without meandering. Further, even when partial meandering occurs, the right and left tubular members 26 are individually rotated to adjust the urging force of the spring 28, so that it is possible to correct the meandering so as not to meander.

In the present embodiment, an example in which the conveying device for the steel sheet is adopted as the pinch roll of the heat insulating material attaching device is exemplified. However, the present invention is also applicable to a steel sheet winding machine and a steel sheet cutting machine. Can be.
