Description

The present invention relates to a system for collecting interleaving paper.

In the manufacturing process of a metal plate such as a steel plate, a metal strip rolled into a strip shape is wound into a coil shape, or a metal strip wound into a coil shape is discharged. When winding the metal band into a coil or transporting the wound metal band, flaws are likely to occur on the surface of the metal band. Therefore, conventionally, in order to prevent scratches from occurring on the surface of the metal strip, when the metal strip is wound into a coil, an interleaving paper is sandwiched between the metal strips.

For example, in the temper rolling equipment disclosed in Patent Document 1, a metal strip is discharged (rewound) from the coil by a rewinding machine. The discharged metal strip is coiled by a winder after being subjected to a predetermined treatment. When the metal strip is unwound by the rewinding machine, the interleaving paper wound together with the metal strip is wound by the interleaving paper winder. Further, when the metal strip is made into a coil, the interleaving paper supplied from the interleaving paper feeder is wound together with the metal strip by the winder.

Japanese Unexamined Patent Publication No. 7-316669

By the way, from the viewpoint of reducing the manufacturing cost, the above-mentioned interleaving paper may be inserted only in the region of the coil where flaws are particularly likely to occur. Specifically, for example, after the winding of the metal strip is started, the interleaving paper may be inserted only in the area of several tens of meters.

When the interleaving paper is partially inserted in this way, in the equipment disclosed in Patent Document 1, when the metal band is ejected from the coil, it is necessary to start collecting the interleaving paper in the middle of the ejection. In this case, it is necessary to stop the equipment once and attach the tip of the interleaving paper to the interleaving paper winder. However, from the viewpoint of reducing the burden on workers, it is desirable to avoid such work as much as possible.

Therefore, an object of the present invention is to provide an interleaving paper collection system that can reduce the burden on the operator.

With reference to FIGS. 1 and 2, the interleaving paper collecting system 10 is a system for collecting the interleaving paper 50 inserted in the coil 40 when the metal band 42 is paid out from the coil 40 in the payoff reel 30. .. The metal strip 42 is, for example, a steel strip. The metal strip 42 paid out from the coil 40 on the payoff reel 30 is conveyed to the next step (for example, a cleaning step) via the pinch roller 32. In the following, in a plan view (see FIG. 2), the direction in which the metal band 42 paid out in the payoff reel 30 travels is defined as the first direction, and the opposite direction is defined as the second direction, with the payoff reel 30 as a reference.

The interleaving paper 50 is usually attached to the surface of the metal band 42 (the outer surface of the metal band 42 in the radial direction of the coil 40) in the coil 40. When the adhesive force between the metal strip 42 and the interleaving paper 50 is weak, the interleaving paper 50 is peeled off from the metal strip 42 by its own weight in the vicinity below the payoff reel 30. On the other hand, when the adhesive force between the metal strip 42 and the interleaving paper 50 is strong, the interleaving paper 50 does not peel off from the metal strip 42 depending on its own weight. In this case, the interleaving paper 50 is peeled off from the metal band 42 in the vicinity of the upper side of the payoff reel 30 by, for example, the air flow generated by the upper blower 141 described later.

In the present embodiment, the interleaving paper winding member 12a has a cylindrical shape, but the interleaving paper winding member 12a may have a prismatic shape.

The drive device 12b rotationally drives the interleaving sheet winding member 12a by being controlled by the control device 16. In the present embodiment, the interlocking sheet winding member 12a is rotationally driven by the driving device 12b when the operator operates the control device 16. That is, in the present embodiment, the interleaving sheet winding member 12a is rotationally driven by remote control by the operator. Various motors can be used as the drive device 12b.

Both ends of the string-shaped member 12c are attached to the interleaving paper winding member 12a. In the present embodiment, the string-shaped member 12c is wound around the interleaving sheet winding member 12a by rotationally driving the interleaving sheet winding member 12a.

The support member 12d is provided so as to extend in a direction orthogonal to the second direction between the interleaving paper winding member 12a and the payoff reel 30 in a plan view. In the present embodiment, the string-shaped member 12c is supported from below by the support member 12d in the state before the collection of the interleaving paper 50 is started. More specifically, when the string-shaped member 12c and the support member 12d are viewed from the payoff reel 30 side in the second direction, the ring 80 (see FIG. 3 described later) is formed by the string-shaped member 12c and the support member 12d.

The airflow generating unit 14a generates an airflow flowing in the second direction from the payoff reel 30 side. In addition, in FIG. 1 and FIG. 2, the air flow is indicated by the arrow of the alternate long and short dash line. However, the examples shown in FIGS. 1 and 2 are shown for easy understanding of the airflow, and do not accurately show the airflow.

The airflow generating unit 14a includes a plurality of feeders. In the present embodiment, the airflow generating unit 14a includes upper blowers 140, 141, lower blowers 142, 143, and auxiliary blowers 144, 145, 146. In the present embodiment, the upper blowers 140 and 141 are arranged above the payoff reel 30, and the lower blowers 142 and 143 and the auxiliary blowers 144, 145 and 146 are arranged below the payoff reel 30.

It is arranged on the second direction side.

The upper blowers 140 and 141 generate an air flow that flows in the second direction through the upper part of the payoff reel 30. In the present embodiment, the upper blower 140 is, for example, an axial fan, and the upper blower 141 is, for example, an air nozzle. In the present embodiment, for example, the airflow pressure generated by the axial fan is smaller than the airflow pressure generated by the air nozzle, and the amount of airflow generated by the axial fan (air volume per unit time). Is greater than the amount of airflow generated by the air nozzle. The number of upper blowers is not limited to the above example, and may be one or three or more. Further, in the present embodiment, at least one upper blower may generate an air flow for peeling the interleaving paper 50 inserted in the coil 40 from the metal band 42. For example, when the adhesive force between the metal band 42 and the interleaving paper 50 is strong and the interleaving paper 50 cannot be peeled off from the metal band 42 due to its own weight, the metal band 42 and the interleaving paper 50 can be used by using an air nozzle as the upper blower 141. A high pressure air flow can be blown from the air nozzle (upper blower 141) between the air nozzle and the air nozzle (upper blower 141). As a result, the interleaving paper 50 can be peeled off from the metal strip 42.

The lower blowers 142 and 143, the airflow flowing in the second direction through the lower part of the payoff reel is generated. In the present embodiment, the lower blowers 142 and 143 are, for example, axial fans, respectively. The number of lower blowers is not limited to the above example, and may be one or three or more. Further, the lower blower may be an air nozzle.

Auxiliary blowers 144 to 146 are provided between the payoff reel 30 and the recovery device 12 in a plan view. The auxiliary blowers 144 to 146 generate an air flow that flows diagonally upward in the second direction from a position below the payoff reel 30. In this embodiment, the auxiliary blowers 144 to 146 are, for example, air nozzles, respectively. The number of auxiliary blowers is not limited to the above example, and may be one or three or more. Further, the auxiliary blower may be an axial fan.

The guide portion 14b is provided between the payoff reel 30 and the collection device 12 in a plan view. In the present embodiment, the guide portion 14b includes a bottom portion 147 and a pair of side wall portions 148, 149 provided so as to rise from the bottom portion 147. In this embodiment, the auxiliary blowers 144 to 146 are provided on the bottom 147.

In the present embodiment, the side wall portions 148 and 149 extend in the second direction so as to pass under the safety fence 60, respectively. In the present embodiment, the space between the side wall portions 148 and 149 serves as a passage for passing the interleaving paper 50 from the coil 40 toward the recovery device 12. In the present embodiment, the side wall portions 148 and 149 are provided so that the distance between the side wall portions 148 and 149 becomes narrower as they approach the collection device 12 from the payoff reel 30 side.

Hereinafter, a method of collecting the interleaving paper 50 by the interleaving paper collecting system 10 will be described with reference to FIG. FIG. 3 is a diagram for explaining the operation of the recovery device 12.

With reference to FIG. 3A, in the state before collecting the interleaving paper 50, the ring 80 is formed by the string-shaped member 12c and the support member 12d. With reference to FIGS. 1 and 2, the interleaving paper 50 peeled off from the metal strip 42 by its own weight or the upper blower 141 is sent to the recovery device 12 side by the air flow generated by the air flow generating unit 14a. Specifically, as shown in FIG. 3B, the interleaving sheet 50 is sent to the interleaving sheet winding member 12a side so as to pass under the regulating member 12e and in the ring 80.

After confirming that the tip of the interleaving paper 50 has passed through the ring 80, the operator operates the control device 16 (see FIG. 1) to rotate the interleaving sheet winding member 12a. As a result, the portion of the string-shaped member 12c forming the ring 80 is pulled upward, and the interleaving paper 50 is hooked on the string-shaped member 12c. Further, by rotating the interleaving paper winding member 12a, the interleaving paper 50 is wound around the interleaving paper winding member 12a. In the present embodiment, since an appropriate tension can be applied to the interleaving paper 50 by the regulating member 12e, the interleaving paper 50 can be smoothly wound around the interleaving paper winding member 12a. As described above, the interleaving paper 50 is collected.

As described above, in the present embodiment, the interleaving paper 50 can be guided to the recovery device 12 by the air flow generated by the air flow generation unit 14a. Therefore, for example, even when the interleaving paper 50 is partially inserted into the coil 40, the equipment (payoff reel 30 or the like) is temporarily stopped in order to collect the interleaving paper 50 when the metal strip 42 is discharged from the coil 40. You don't have to. As a result, the burden on the operator can be reduced.

Further, since the operator does not need to approach the equipment in order to guide the interleaving paper 50 to the collection device 12, the safety of the operator is improved.

Further, in the present embodiment, when the interleaving paper 50 is peeled off from the metal strip 42 by its own weight, the interleaving paper 50 can be appropriately sent to the recovery device 12 side by the air flow generated by 142 and 143. On the other hand, when the adhesive force between the metal strip 42 and the interleaving paper 50 is strong, for example, the interleaving paper 50 can be peeled off from the metal strip 42 by the upper blower 141, and the interleaving paper 50 is generated by the airflow generated by the upper blower 140. Can be appropriately sent to the recovery device 12 side.

Further, in the present embodiment, the interleaving paper 50 peeled off from the metal band 42 can be smoothly sent to the recovery device 12 side by the air flow generated by the auxiliary blowers 144 to 146.

Further, in the present embodiment, the interleaving paper 50 passes between the side wall portions 148 and 149. Thereby, when the interleaving paper 50 is sent from the coil 40 to the collection device 12, the side wall portions 148 and 149 can prevent the interleaving paper 50 from coming into contact with other structures. Therefore, the interleaving paper 50 can be sent to the collection device 12 more smoothly.

Further, in the present embodiment, the interleaving paper 50 can be wound around the interleaving paper winding member 12a in a state where the interleaving paper 50 is hooked by the string-shaped member 12c. As a result, the slip of the interleaving paper 50 with respect to the interleaving paper winding member 12a can be sufficiently suppressed, so that the interleaving paper 50 can be efficiently collected.

According to the present invention, it is possible to reduce the burden on the operator when collecting the interleaving paper.
