(Constitution)
FIG. 1 is a schematic configuration diagram illustrating the arrangement of belt wrappers in the present embodiment.
In FIG. 1, a steel strip 1 which is a belt-like body sent from the right side is changed from a right upper side to a left lower side and conveyed toward a tension reel 2, and along the tension reel 2 by a belt wrapper. This is an example of winding.

  The belt wrapper is configured by a plurality of guide rolls 3 (in the case of four guide rolls 3 illustrated in FIG. 1) arranged on the outer peripheral side of the tension reel 2, and an endless annular belt 4 is stretched over the steel belt. When winding 1 around the tension reel 2, the entry side guide roll 3a at the winding start position example and the exit side guide roll 3b at the winding end position are brought close to the tension reel 2 so that the entry side guide roll 3a. The belt 4 between the outlet guide roll 3b and the outer guide surface 3b is pressed against the outer diameter surface 2a of the tension reel 2 with a predetermined tension.

Here, in this embodiment, two sets of the belt 4 and the guide roll 3 are arranged along the width direction of the tension reel 2 as shown in FIGS. 4 and 5 to be described later. A belt 4 and a guide liner described later are provided.
Further, a tip guide frame 5 is provided so as to be rotatable around the axis coaxially with the axis of the exit guide roll 3b. The tip guide frame 5 is rotatable around the axis by driving the cylinder device.

  As shown in FIG. 2, which is a schematic diagram, the distal end guide frame 5 is directed toward the left and right wall plate portions 6 respectively disposed on both sides in the axial direction of the output side guide roll 3b and the winding start position S of the tension reel 2. There is provided a top plate guide portion 7 facing the lower surface (surface on the tension reel side) of the steel strip 1 to be sent. The left and right wall plate portions 6 and the top plate guide portion 7 extend toward the winding start position S, and a first guide liner 8 is provided at the front end portion of the top plate guide portion 7 in the extending direction.

  As shown in FIGS. 3 to 6, the first guide liner 8 is disposed so as to be bridged between the left and right wall plate parts 6, thereby having a width equivalent to that of the output side guide roll 3 b and a tension reel. A liner surface 8 a facing 2 is a cylindrical surface having an arcuate cross section that follows the outer diameter surface 2 a of the tension reel 2. The curvature of the arc is set to the same or substantially the same curvature as the outer diameter surface 2a of the tension reel 2.

  Further, in the present embodiment, as shown in FIGS. 3 to 5, the second guide liners 9 are also provided in the portions of the left and right wall members facing the outer diameter surface 2 a of the tension reel 2. Each of the second guide liners 9 extends from the side surface position of the exit side guide roll 3b toward the winding start position S and faces the outer diameter surface 2a of the tension reel 2 in the second guide liner 9. The surface 9a is a cylindrical surface having an arc cross section that follows the outer diameter surface 2a of the tension reel 2. The curvature of the arc is set to the same or substantially the same curvature as the outer diameter surface 2a of the tension reel 2. In the case where the diameter of the tension reel 2 changes in accordance with winding, the curvature is based on the outer diameter surface 2a of the tension reel 2 at the start of winding.

  Here, in this embodiment, the width | variety of the 1st guide liner 8 is set to the same or substantially the same dimension as the width | variety of the said output side guide roll 3b. The left and right second guide liners 9 are positioned outward in the width direction with respect to the outlet guide roll 3b, so that the first guide liner 8 and the second guide liner 9 are viewed from the radial direction of the tension reel 2. No interference. However, the first guide liner 8 and the second guide liner 9 are arranged so as to partially overlap each other when viewed from the axial direction of the tension reel 2.

Furthermore, in the present embodiment, as shown in FIG. 6, at least in the overlap portion of the first guide liner 8 and the second guide liner 9, each of the first guide liner 8 and the second guide liner 9 from the central axis of the tension reel 2 is used. The distances to the liner surfaces 8a and 9a are set to be the same or substantially the same.
Here, the material of the first guide liner 8 and the second guide liner 9 is, for example, a copper alloy SAE430B having wear resistance.

(Function and effect)
Next, the effect of the winding device will be described.
When starting the winding of the steel strip 1 on the tension reel 2, the entry-side guide roll 3a and the exit-side guide roll 3b are moved to the vicinity of the winding start position S by moving the entry-side guide roll 3a and the exit-side guide roll 3b. The belt 4 is pressed with a predetermined tension.
In this state, the leading end portion of the steel strip 1 that has been sent passes between the top plate guide portion 7 and the entry side guide roll 3a, and at the winding start position S, the outer diameter surface 2a of the tension reel 2 is reached. The steel strip 1 is wound around the outer diameter surface 2 a of the tension reel 2 as it is pressed by the belt 4.

Furthermore, when the tip end of the steel strip 1 moves to the position of the exit side guide roll 3b as the tension reel 2 rotates, the belt 4 is not restrained to the outer diameter surface 2a of the tension reel 2, but the second guide liner 9, the tension reel 2 is guided toward the first guide liner 8 in a state where the lift from the outer diameter surface 2 a is restricted.
Subsequently, the leading end portion of the steel strip 1 is guided toward the winding start position S in a state where the lifting from the outer diameter surface 2a of the tension reel 2 is regulated by the second guide liner 9 to the first guide liner 8. Then, it is advanced below the subsequent steel strip 1.

  With the above operation, even if the front end portion of the steel strip 1 is not pressed against the outer diameter surface 2a of the tension reel 2 by the belt 4 at the position of the exit guide roll 3b, the second guide liner 9 causes the tension reel 2 to Is lifted from the outer diameter surface 2a, and is guided toward the first guide liner 8 along the outer diameter surface 2a. This prevents the tip of the steel strip 1 from floating from the tension reel 2, thereby preventing the tension reel 2 from shifting in the width direction.

Further, since the second guide liner 9 and the first guide liner 8 are partially overlapped, the steel strip 1 is attached to the tension reel 2 even during the transition of the guide from the second guide liner 9 to the first guide liner 8. From being lifted more than allowable.
And as a result of being guided by the 1st guide liner 8 as it is, the front-end | tip part of the steel strip 1 is inserted into the lower side of the following steel strip 1 along the outer-diameter surface 2a of the tension reel 2, As a result Is prevented from sticking to the subsequent steel strip 1. This suppresses the occurrence of loose winding due to bending of the tip of the steel strip 1, and prevents the coil from being telescopically (developed) due to the tip of the steel strip 1 being displaced in the width direction.
As a result, the winding property is improved.

  In the present embodiment, the liner surfaces 8a and 9a of the first guide liner 8 and the second guide liner 9 are circular cylindrical surfaces that follow the outer diameter surface 2a of the opposing tension reel 2. Since guidance is possible over the entire surface of 8a and 9a, the surface pressure on the liner surfaces 8a and 9a can be suppressed, and the wear of the liner can be reduced. For this reason, in this embodiment, a comparatively soft copper alloy etc. can be employ | adopted as a material of the guide liners 8 and 9, and this has the effect which suppresses the flaw generation | occurrence | production on the steel strip 1 surface further.

  Here, the liner surface 8a of the first guide liner 8 has a width equivalent to the width of the exit guide roll 3b, whereas the liner surface 9a of the second guide liner 9 is narrow, so the first guide liner The second guide liner 9 tends to have a higher surface pressure than 8. For this reason, it is preferable to extend the 1st guide liner 8 to the said output side guide roll 3b side so that it may approach the output side guide roll 3b as much as possible.

  Further, in the overlapping portion of the first guide liner 8 and the second guide liner 9, it is preferable that both liner surfaces 8a and 9a are set to be flush with each other so that there is no step between the liner surface 8a and the liner surface 9a. However, when a design error is taken into consideration, the end surface of the liner surface 8a of the first guide liner 8 is closer to the center side of the tension reel 2 than the liner surface 9a of the second guide liner 9 at the end position on the exit guide roll 3b side. It is better to set the distance slightly larger (see FIG. 6) so as to prevent it from being caught when shifting from the guidance by the second guide liner 9 to the state of being mainly guided by the first guide liner 8.

  Here, in the present embodiment, in consideration of ease of operation, the tip guide frame 5 provided with the first guide liner 8 and the second guide liner 9 is pivotally supported on the shaft of the exit guide roll 3b. However, it may be supported by a portion different from the shaft of the outlet guide roll 3b. In the present embodiment, the tip guide frame 5 is illustrated as being rotatable about the axis, but the present invention is not limited to this. For example, the front end guide frame 5 may be provided so as to be able to advance and retract in the radial direction toward the outer diameter surface 2a of the tension reel 2.

  Here, in the above description, the case where two sets of the belt 4 and the guide roll 3 are arranged along the width direction of the tension reel 2 is illustrated, but one set may be used, or three or more sets may be arranged. May be. Moreover, the 2nd guide liner 9 arrange | positioned between the exit side guide rolls 3b arranged in a width direction may be one guide liner shared by two sets.
