Description

The present invention relates to a rewind payoff reel used when rewinding a loose coil.

When rewinding a loosely wound coil, a conventional rewinding payoff reel that rewinds the coil using a cantilever-shaped mandrel causes winding to occur at a loosened position when rewinding. A phenomenon (so-called telescoping phenomenon) that protrudes in the width direction and shifts to a telescope shape occurs, and rewinding becomes impossible. Therefore, a fixed face plate is attached to the base side of the mandrel, and a detachable face plate is attached to a predetermined position on the front side of the mandrel so as to rotate integrally with the coil, so that even if a telescopic deviation occurs in the coil during rewinding Discloses a payoff reel that enables coil rewinding (see, for example, Patent Document 1). Further, in order to hold the presser plate that contacts and presses the coil protruding during rewinding, a plurality of recesses into which the protrusions provided on the presser plate can be fitted are provided in the mandrel segment according to the coil width. (For example, refer to Patent Document 2).

The face plate attaching / detaching mechanism 15 is located behind the front side of the mandrel 13 via the support member 28 connected to the housing 22 of the rotation driving unit 11 (the direction in which the strip plate 55 is pulled out from the coil 12 inserted in the mandrel 13 is set to the front). A support column 29 that is erected, a rotation arm 30 that is pivotally attached to the support column 29 and moves in a horizontal plane, and a tip of the rotation arm 30 that is provided via a bearing 31 at the tip of the mandrel 13 A revolving part 34 that is connected via a clutch mechanism 33 and rotates integrally with the mandrel 13 is provided. The base side of the rotating arm 30 is connected to the piston 48 of the fluid pressure cylinder 47 attached to the support member 28.
In addition, when the turning arm 30 is turned by 90 ° around the support post 29, the central axis of the turning part 34 provided at the front part of the turning arm 30 and the central axis of the mandrel 13 are overlapped. The standby position of the turning unit 34 is adjusted.

Here, the swivel unit 34 is provided with a connecting member 36 including, for example, a plurality of mounting bases 35 (six in the embodiment divided into six in the circumferential direction) extending radially outward in the radial direction. The fluid pressure cylinders 18 are respectively attached to the mounting bases 35 arranged at positions facing each other across the center. The fluid pressure cylinder 18 is attached so that its central axis is parallel to the axial direction of the mandrel 13, and the tip of the piston 37 of the fluid pressure cylinder 18 is connected to the second boss portion 26. Further, bearings 38 are respectively attached to the remaining mounting bases 35, guide rods 39 are inserted into the respective bearings 38, and the tip portions of the respective guide rods 39 are connected to the second boss portion 26. The fluid for operating the fluid pressure cylinder 18 is supplied via a pipe (not shown) through a rotary joint 40 provided at the base of the swivel unit 34. With the above configuration, the second face plate 16 can be detachably attached to the front side of the mandrel 13 by the face plate attaching / detaching mechanism 15, and the fluid pressure cylinder 18 is attached to the attached second face plate 16. By operating, the second face plate 16 can be moved in the axial direction of the mandrel 13 while preventing rolling by the guide rod 39.

The first face plate moving means 17 has a rail (not shown) along the axial direction of the mandrel 13 on both sides of the lower surface side (a direction perpendicular to the axis of the mandrel 13 in plan view) on which the housing 22 is placed. Z)) is attached to the base 41. Further, the first face plate moving means 17 includes a wheel support base 43 provided with a plurality of wheels (not shown) that abut on each rail and movably supports the base 41 and is fixed to the reel mounting base 42. And a moving fluid pressure cylinder 45 having a piston 44 attached to the base of the wheel support base 43 and connected to the base side of the base 41. Here, a lateral wheel 49 and a longitudinal wheel 50 are provided on the outer surface and the lower surface of the front side region of the support member 28, respectively. The vertical wheel 50 abuts on a rail 52 provided on a first mounting base 51 fixed to the reel mounting base 42, and the horizontal wheel 49 is a second mounting standing on the first mounting base 51. It abuts on a rail 54 provided on the side of the base 53.

Accordingly, when the fluid pressure cylinder 45 for movement of the first face plate moving means 17 is operated, the base 41 can be moved along the axial direction of the mandrel 13, and the first face plate 14 is moved to the rotation drive unit 11. At the same time, the mandrel 13 can be moved in the axial direction. At this time, the front side region of the support member 28 moves with the rotation drive unit 11 while being supported by the horizontal wheels 49 and the vertical wheels 50, so that the face plate attached to the support member 28 can be attached and detached even if the rotation drive unit 11 moves. The positional relationship between the mechanism 15 and the rotation drive unit 11 is kept constant. As a result, the positional relationship between the mandrel 13 and the face plate attaching / detaching mechanism 15 is also kept constant, and the second face plate 16 can be detachably attached to the front side of the mandrel 13 by the face plate attaching / detaching mechanism 15.

Here, the fluid pressure cylinders 18 provided in the first face plate moving means 17 and the face plate attaching / detaching mechanism 15 can be driven independently. Therefore, the first face plate 14 can be pressed against the proximal end face of the coil 12, and the second face plate 16 can be pressed against the distal end face of the coil 12. As a result, the installation positions of the first and second face plates 14 and 16 can be adjusted according to the width of the coil 12, respectively.

Next, the rewinding operation of the coil 12 by the rewind payoff reel 10 according to the embodiment of the present invention will be described.
First, the first face plate moving means 17 of the rewind payoff reel 10 is operated to move the position of the rotation drive unit 11, and the installation position of the first face plate 14 is adjusted to a predetermined reference position. Here, the reference position means that when the coil with the maximum width is inserted into the mandrel 13 so that the center in the width direction of the coil coincides with the line center of the transport path (not shown) of the strip rewound from the coil. The position where one face plate 14 abuts on the proximal end face of the maximum width coil is indicated.
Next, the coil 12 is placed on a coil car (not shown), conveyed to the rewind payoff reel 10, and inserted into the mandrel 13. Then, the coil car is operated to adjust the position of the coil 12 so that the center line in the width direction of the coil 12 coincides with the line center line of the transport path of the wound coil 12.

When it is confirmed that the center in the width direction of the coil 12 placed on the coil car coincides with the line center of the transport path, the first face plate moving means 17 is operated to move the position of the rotation driving unit 11 to the first. The face plate 14 is pressed against the proximal end face of the coil 12 inserted into the mandrel 13. And the diameter of the mandrel 13 is expanded, the coil 12 is fixed to the mandrel 13, and the coil car is retracted. When the coil with the maximum width is inserted into the mandrel 13, the base side end face of the coil and the first face plate 14 come into contact with each other, so that the operation of the first face plate moving means 17 can be omitted.

When the coil 12 is fixed to the mandrel 13, the face plate attaching / detaching mechanism 15 is driven to turn the rotating arm 30 by 90 ° from the standby position (shown by a two-dot chain line in FIG. 1), and is provided on the second face plate 16. The front side of the mandrel 13 is inserted through the hole. As a result, the tip portion of the mandrel 13 and the turning portion 34 are connected via the clutch mechanism 33, and the second face plate 16 is attached to the front side of the mandrel 13. Then, by operating the fluid pressure cylinder 18 and extending the piston 37 and pressing the second face plate 16 against the front end face of the coil 12, the attachment of the coil 12 to the rewinding payoff reel 10 is completed.

Subsequently, as shown in FIG. 3, the strip plate 55 forming the coil 12 is discharged to the conveyance path and pulled out by a bridle roll (not shown). The belt plate 55 is rewound in a state where a tensile force is applied in the drawing direction by adjusting the rotation speed of the rotation driving unit 11 rotated by the electric motor 21 by the speed reducer 20. At this time, winding tightening occurs at a loose part of the coil 12, but since both end faces of the coil 12 are pressed by the first and second face plates 14 and 16, the end face of the coil 12 protrudes in the width direction. It is possible to prevent the phenomenon of shifting to the shape. Thereby, when unwinding the strip 55 from the coil 12, it can prevent that the edge part of the strip 15 is pressed and damaged by the 1st, 2nd face plates 14 and 16, and a product yield improves.

Here, the first face plate 14 is attached to the mandrel 13 and can rotate integrally with the mandrel 13. Further, the turning portion 34 of the face plate attaching / detaching mechanism 15 to which the second face plate 16 is attached is connected to the tip end portion of the mandrel 13 and rotates integrally with the mandrel 13. For this reason, when the coil 12 is rewound, each end face of the coil 12 and the first and second face plates 14 and 16 are not rubbed, so that damage caused to the end of the coil can be avoided.

As described above, the present invention has been described with reference to the embodiment. However, the present invention is not limited to the configuration described in the above-described embodiment, and the matters described in the scope of claims. Other embodiments and modifications conceivable within the scope are also included.
