[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer device for changing the transfer direction of a coil for winding a steel strip.

[0002]

2. Description of the Related Art Conventionally, a coil transfer type and an overhead crane type have been used as techniques for suspending and transferring a strip winding coil, but have the following problems.

(1) A frame mounted with a coil transfer type hook device is a four-wheel truck having a wide rail span. For this reason, linear transfer is possible, but application to curved transfer is extremely difficult due to a large rail radius. (2) Overhead crane type L-shaped transfer (transportation at right angle in the transfer direction) is possible because of the function of traveling and traversing, but the coil is suspended on the rope, so it is special for positioning and preventing the rope from swaying. It requires technology, and its structure and mechanism are complicated and expensive.

SUMMARY OF THE INVENTION An object of the present invention is to carry out curved transfer of a strip winding coil with a small facility in a small area, and to easily perform positioning and operation.

[0005]

In order to achieve the above object, the present invention provides an arcuate horizontal guide rail along the circumference above the floor.
The center of curvature of the oblique horizontal mount supported on the lower surface of the orthogonal horizontal mount and the center of curvature of the guide rail connects both ends of the mount.
At the center, the base end of the horizontal rotating arm is pivotally supported by an upright shaft, the tip is supported by the guide rail via a guide roller, and the tip is restrained by an upright guide device. A vertically movable lifting platform that vertically moves without rotating, is provided with a coil insertion hook on the lifting platform so as to be reciprocally slidable in a direction perpendicular to the horizontal rotating arm. The driving device is constituted by the coil transfer equipment according to the above invention, wherein the driving device is a horizontal cylinder and an upright cylinder.

It is lowered by the upright driving device 12 (the upright cylinder 12 ′) without rotating in the horizontal direction, and after inserting the insertion hook 10 into the coil 13, the lifting table 9 is raised by the driving device 12.

When the horizontal driving device 11 (horizontal cylinder 11 ′) rotates the horizontal turning arm 5 at a fixed angle about the upright shaft 6, the tip 5 ″ of the arm 5 becomes a guide roller 7.
Is supported by the horizontal guide rails 2 via the shaft and moves at a constant angle along the circumference to convert the transfer direction a of the coil 13 into the b direction by a fixed angle, and the upright drive device 12 (the upright cylinder 1
By 2 '), the elevator 9 can be lowered and the coil 13 suspended from the hook 10 can be lowered to the floor surface 1.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Three pillars 14 are erected on the floor 1 and
An orthogonal horizontal base 3 is mounted on the base 4, and the horizontal guide rail 2 along the circumference is supported on the lower surface of the base 3. The rail 2 can be arcuate, partially notched or perfect circular.

The center of curvature 4 of the rail 2 is located at the center of the oblique horizontal base 3 'connecting the orthogonal horizontal bases 3, 3, and at the center of curvature 4, the base end 5' of the horizontal rotating arm 5 is provided. Upright shaft 6
Pivoted by. The tip 5 ″ of the rotating arm 5 is supported by the guide rail 2 via guide rollers 7, 7.
It can be turned 90 degrees by the horizontal cylinder 11 ′ from the solid line position to the virtual line position in FIG. The rotation angle is not limited to 90 degrees.

As shown in FIG. 2, upright rods 8 ", 8" provided on an elevating platform 9 are slidably fitted in a pair of upright guide holes 8 ', 8' at the tip 5 ". an upright guide device 8, 8 are formed, vertically and by elevating the elevation frame 9 without rotation in the horizontal direction is restrained in the device 8, 8, and the lifting platform 9
Has an opposite hook 10 inserted into the steel strip winding coil 13,
10 are provided so as to be reciprocally slidable in the facing direction.

As shown in FIG. 5, the opposing hooks 10 and 10 extend along the lower surface of the elevator 9 to form mutually opposite opposing spirals 15 and 15.
Are provided symmetrically, female screws 16, 16 are screwed into the spirals 15, 15, respectively, and the hooks 10, 10 are provided at the lower ends of legs 17, 17, which are suspended from the female screws 16, 16, respectively. It is. However, the present invention is not limited to the opposed hooks 10 and 10, and may be a single one-way hook.

The horizontal rotating arm 5 can be reciprocated in the horizontal direction about the upright shaft 6 by a horizontal cylinder 11 'connecting the arm 5 and the gantry 3, and can be rotated by the horizontal cylinder 11' or a rotary actuator or the like. The horizontal driving device 11 is formed. The elevator 9 is at the tip 5 ″.
Is connected to the upright cylinder 12 'provided in the above, and can be moved up and down by being restrained by the guide devices 8, 8;
The upright cylinder 12 'forms a vertical drive.

As shown in FIG. 4, the horizontal guide rail 2 is formed of an I-shaped steel, and guide rollers 7, 7 are supported on both sides of the rail 2.

Reference numeral 18 in the drawing denotes a stopper for the horizontal rotating arm 5, 19 is a coil swing preventing arm, and 20 is the preventing arm 19
, A rotary hydraulic motor for the above-mentioned spirals 15, 15 provided at the tip 5 ″, and 22 a spiral hydraulic motor.
Reference numerals 5 and 15 denote rotation sprockets, and reference numeral 23 denotes a rotation chain.

[0015]

Since the present invention is constructed as described above, the transfer direction conversion or the curve transfer of the coil 13 can be performed by one actuator, the area for the direction change is small, the structure and mechanism are simple, and the whole equipment is compact. Not only become
Positioning control and operation can be easily performed.
