Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coil wrapper suitable as a winding auxiliary device for a steel strip winding device in rolling equipment, finishing equipment, etc.

A tension reel, generally known as a winding device, is usually provided with a belt trapper next to it as a winding auxiliary device.

This belt trapper uses the winding force of the drum that is driven along the outer circumference of the drum to bend the end of the steel strip and press it against the drum, and uses the torque of the drum to wind it up. Since the belt has sharp edges due to shear cutting, the belt at the inlet port is seriously damaged during winding, and it often needs to be replaced, and replacement takes a considerable amount of time.

Therefore, plate-guided coil wrappers are used in some cases, which do not require belt replacement. However, when using this type of coil wrapper to change the diameter of the drum, a guide plate is used to hold the steel strip against the drum. There is a problem in that the belt and guide rollers do not freely follow the diameter of the drum, and therefore the tightening force of the steel strip is weak and cannot be used. The present invention has been made with the aim of improving the current state of the art.

Embodiments of the present invention will be described in detail below with reference to the drawings.

1 is the drum of the tension reel, 2 is the steel band, 3 is the wrapper stand, and 4 is the swing frame, which is suspended from the arm 3' of the wrapper stand 3 via the pin 5, and is connected to the cylinder via the lever 6. 7, and swings by its driving operation.

This swing frame 4 has a lapper frame which is arranged opposite to a movable frame 8 connected to its lower end via a pin 9 so as to sandwich the drum 1, and whose strip steel winding intake side is between the swing frame 4 and the drum 1. The pin 9, which is movably supported in the long hole a cut at the lower end of the swing frame 4, is moved into the long hole a by the worm adjustment device 11.
The wrapper frame can be freely expanded or contracted by moving an adjustment screw 12 inserted therein and by operating a cylinder 10 connected to a pin 9. The movable frame 8 is raised up to face the swing frame 4 by a cylinder 13 connected thereto, and arcuate surfaces B and c exist on the facing surfaces of the swing frame 4 and the movable frame 8 with a slight gap from the drum 1. is formed.

Also, the arc surface B of the swing frame 4 and the movable frame 8,
A presser guide roller 14a that is rotatably driven as described later is disposed between the upper ends of c, and high friction rollers are provided at the lower end of the arcuate surface b of the swing frame 4 and the upper and lower ends of the arcuate surface c of the movable frame 8, respectively. Drive presser guide roller 14a
, 14b, 14c, and 14d are attached. 1 of them
4a is swingably attached to the swing lever 15 supported on the swing frame 4, and rotates in conjunction with the prime mover 16 via transmission mechanisms 17 to 21, and is connected to the upper surface of the swing lever 15. The rolling action of the cylinder 22 presses the steel strip 2 wound around the drum 1 to apply a strong seaming force. These presser foot guide rollers 1
A large number of auxiliary guide rollers 29 connected to a cylinder-type pressing device are arranged between 4a and 14d. The auxiliary guide rollers 29 may be operated by one cylinder 23, for example, one or two in a set, and depending on the location, the link mechanism 26 may be attached to the bracket 28. Two sets of guide rollers connected via 27 may be operated by one cylinder 24 or 25. Adopting the latter method allows the required number of cylinders to be reduced. Also presser guide roller 14b,
When the wrapper frame is reduced, the auxiliary guide roller 29 disposed between the presser guide rollers 14b and 14c
4c from the outer peripheral surface of the drum 1 so as not to interfere with the rotation of the drum 1.
The support pins 30 of the presser guide rollers 14b and 14c are connected to the support pins 30 of the presser guide rollers 14b and 14c via link mechanisms 31 and 32 so as to press the wrapper frame, and are configured to operate in conjunction with the expansion and contraction of the wrapper frame. This configuration has the advantage of simplifying the mechanism and saving on pressing devices such as cylinders. However, this is not necessarily limited to this, and a pressing device such as a cylinder may also be used. Note 33
There is an entrance guide. The roll-type coil wrapper according to the present invention has the above-mentioned configuration, and when the winding is to be carried out to the minimum diameter of the drum, the cylinder 10 is set in a retracted state as shown in FIG. The presser guide roller 14b is brought into contact with the outer periphery of the drum 1, and then the swing lever 15 is tilted by the cylinder 22 to position the presser guide roller 14a so as to contact the outer periphery of the drum.

Next, the cylinder 13 is actuated to raise the movable frame 8 to bring the presser guide rollers 14c and 14d into contact with the outer periphery of the drum, and the cylinders 23, 24, and 25 are actuated to raise the auxiliary guide roller 29. After pressing the outer peripheral surface of the drum and preparing to receive it, the prime mover 16 is driven to pass the steel strip 2 along the entrance guide 33 and start winding it. When winding, as shown in FIG. 2, the adjustment screw 12 is pulled by the worm adjustment device 11, the support pin 9 of the movable frame 8 is moved by the cylinder 10, and after setting it at the tip position of the adjustment screw 12, the drum The steel strip is wound up by the same operation as in the case of the minimum diameter.As described above, the present invention includes a wrapper frame that can be expanded and contracted, a presser guide roller that is rotated along the outer periphery of the drum, and a high Since a friction-driven presser guide roller and a large number of auxiliary guide rollers with variable pressing strokes are arranged between the rollers, a single coil wrapper can suitably wind up a copper plate regardless of the drum diameter. In addition, the pressing force and pushing force are doubled by rotationally driving the presser guide roller 14a on the entry side, thereby promoting bending of the edge of the plate and making it possible to wind the steel strip while firmly tightening it.
