Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coil rewinding device.

[0002]

[Prior art]

 Various devices have been proposed as a device for guiding the tip of a coil without causing clogging of the tip of the strip. The plate guide or plate table is a drive conveyor system. The plate guide or plate table is a magnet conveyor type. Before inserting the coil into the rewinding device, the outer circumference of the coil is corrected by a shape correcting device before starting rewinding.

[0003]

[Problems to be solved by the device]

 However, the conventional device that guides the tip of the coil without hitting it has an extremely large weight, requires a large amount of power, and has a complicated driving method.

The present invention has been made under these circumstances, and its purpose is to provide a coil rewinding device that is light in weight, does not require large power, has a simple operation plan, and is resistant to failure. In offer.

[0005]

[Means for Solving the Problems]

 The present invention is a coil rewinding device comprising a rewinding reel, a plate passing table having rollers arranged on the surface thereof, and a pinch roll which can be raised and lowered.

Further, in order to enable more stable coil rewinding, the shaft cores of the rollers arranged on the threading table are arranged at acute angles with respect to the line center in the coil rewinding direction. It is a coil rewinding device characterized by the above.

[0007]

[Action]

 After inserting the coil into the rewind reel, rewind it along the threading table with rollers arranged on the surface, lower pinch roll placed on the line, and rewind to the rising pinch roll, upper pinch roll This is a device that lowers and applies tension to the coil with both pinchels, leading to full-fledged threading work.

The coil is rewound along the roller while leaving a curl, so that the friction is reduced and the coil is smoothly threaded.

Further, by arranging the shaft cores of the rollers arranged on the threading table so as to form an acute angle with respect to the line center in the coil rewinding direction, the centering of the coil being rewound while contacting is performed. (Aligning action) The force works, and it is possible to rewind even more smoothly.

【Example】

 An embodiment of the coil rewinding device of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a diagram showing an entire coil rewinding device to which the present invention is applied. The coil 8 is inserted into the rewind reel 14, and the press roll 13 is applied to the coil to prevent the coil from loosening and rotate the reel. The tip of the coil is opened by the threading table 10, and is rewound to the pinch roll 11 along the roller 1 on the surface of the threading table. When the tip of the coil reaches the pinch roll, the upper pinch roll descends, rewinds while applying tension, passes through the feed roll 12, and completes rewinding.

In this embodiment, the roller 1 is also arranged on the surface of the upper threading guide 9 so that the coil 8 having a curling habit can be smoothly fed to the pinch roll without causing scratches due to the guide. I am taking into consideration that

When the threading table 10 and the threading guide 9 on the upper side are preferably arcuate shapes larger than the minimum outer diameter of the rewinding coil, the reaction force of catching at the tip of the rewinding coil is small and the threading plate is It's smooth.

Further, the elevating and lowering of the upper strip guide 9 is carried out at the same time as the elevating and lowering of the pressing roll 13 by a driving device (not shown), descends in preparation for rewinding and rises upon completion of striping. The threading table 10 also moves up and down and expands and contracts by the cylinders 6 and 7 around the fulcrum 3 concentric with the lower pinch roll in accordance with the outer diameter of the rewinding coil, as instructed by an automatic calculator (not shown). Similarly, it descends when the threading is completed.

FIG. 2 is an enlarged perspective view of an embodiment of the roller 1 of the plate passing table 10 which is an essential part of the present invention. In this embodiment, the number of rollers is small and the rollers are staggered in order to cover a large area. This also facilitates the work for attaching the roller 1 to the roller fitting 4 with the bolt 2.

FIG. 3 is a sectional view taken along line BB of FIG. FIG. 4 is a plan view of FIG. FIG. 5 is a plan view of a portion similar to the portion shown in FIG. Attach the roller 1 to the mounting bracket 4 at the same angle so that the direction of rotation of the roller 1 is centered from the left and right with respect to the line center of the coil rewinding direction, and center the coil rewound in contact with the roller ( (Centering action) Considering that the force works.

FIG. 6 is a plan view of another embodiment of the same portion as the portion shown in FIG. This is an example in which the mounting bracket 4 of the roller 1 is mounted on the plate table 10 at an angle of 90 degrees or less so as to face the line center in the coil rewinding direction. The rollers of the upper thread guide may also be arranged in a zigzag manner and at an angle so that a centering (centering) force works.

[0018]

EFFECTS OF THE INVENTION The coil rewinding device of the present invention is light in weight, does not require a large amount of power, and has a simple operating method. Moreover, the coil rewinding device does not get caught or pinched in the pinch roll. It can be done.
