Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to a transfer equipment for changing the transfer direction of a strip steel winding coil.

[0002]

[Prior art]

  As a technique for suspending and transporting the steel strip winding coil, coil transfer type and ceiling The lane type has been used conventionally, but each had the following problems.

[0003]   (1) Coil transfer type   The frame equipped with the hook device is a four-wheeled truck with a wide rail span. Therefore straight line Transfer is possible, but application to curved transfer is extremely difficult due to the large rail radius. It   (2) Overhead crane type   L-shaped transfer (transfer at right angles to the transfer direction) is possible because it has the functions of running and traversing However, since the coil is suspended on the rope, it can be used for positioning and steadying the rope. Special technology is required, and the structure and mechanism are complicated and expensive.

[0004]

[Problems to be solved by the device]

  In this plan, the curved strip winding coil is transferred in a small area in a small facility, and The purpose is to facilitate positioning and operation.

[0005]

[Means for Solving the Problems]

  To achieve the above objectives   A horizontal guide rail along the circumference is supported above the floor by a gantry, and the guide rail is The base end of the horizontally rotating arm is pivotally supported by the upright shaft at the core, and the tip end is guided by a guide roller. Is supported by the guide rails and is supported by the upright guide device at its tip end to move up and down. Coil transfer equipment provided with an elevator and an elevator hook with an insertion hook in the coil   The driving devices for the horizontal rotation arm and the lifting platform are the horizontal cylinder and the upright cylinder. Coil transfer equipment described above   Composed by.

[0006]

[Action]

  In the present proposal, the lift 9 is moved upright by the upright guide device 8 (upright cylinder 12). -12 ') to lower it and insert the insertion hook 10 into the coil 13 The elevator 12 is raised by the moving device 12.

[0007]   Then, the horizontal driving arm 11 (horizontal cylinder 11 ') is used to directly move the horizontal rotation arm 5. When the arm 5 is rotated about the vertical shaft 6 by a certain angle, the tip 5 ″ of the arm 5 is guided by the guide roller 7. Then, the coil 1 is supported by the horizontal guide rail 2 and moved by a predetermined angle along the circumference. The transfer direction a of 3 is converted to the b direction by a certain angle, and the upright drive device 12 (upright cylinder 12 ') lowers the platform 9 and suspends the coil 13 from the hook 10. Can be dropped onto the floor 1.

[0008]

【Example】

  A pillar 14 is erected on the floor surface 1, a horizontal mount 3 is installed on the pillar 14, and a circle is attached to the mount 3. Supports a horizontal guide rail 2 along the circumference. The rail 2 has an arc shape or a partially cutout circular shape Can be a perfect circle.

[0009]   The center of curvature 4 of the rail 2 is an oblique horizontal mount 3 that connects the orthogonal horizontal mounts 3 and 3. Of the horizontal pivot arm 5 at the center of the curvature 4 by means of the upright shaft 6. Is pivotally supported. The tip portion 5 ″ of the rotating arm 5 is guided by the guide rollers 7, 7 It is supported by the guide rail 2 and along the rail 2 with the upright shaft 6 as the center. Can be rotated 90 degrees by the horizontal cylinder 11 'from It The rotation angle is not limited to 90 degrees.

[0010]   As shown in FIG. 2, the tip portion 5 "is provided with a pair of upright guide holes 8'and 8'ascending / descending table 9 '. The upright rods 8 ", 8" provided on the above are slidably fitted to form the upright guide devices 8, 8. The elevators 9 are lifted and lowered by being restrained by the devices 8 and 8, and the steel strip winding coil is attached to the elevators 9. Opposite hooks 10 and 10 to be inserted into the sleeve 13 are provided so as to be reciprocally slidable in opposite directions. .

[0011]   As shown in FIG. 5, the opposing hooks 10 and 10 are mutually opposed along the lower surface of the lifting table 9. Opposing spirals 15 and 15 are provided symmetrically, and female screws 16 are respectively attached to the spirals 15 and 15. , 16 are screwed together, and the above-mentioned hooks are attached to the lower ends of the legs 17, 17 which are hung on the female screws 16, 16. 10 and 10 are provided. However, it is limited to the opposite hooks 10 and 10. Instead, it may be a one-way hook.

[0012]   The horizontal rotating arm 5 is erected by a horizontal cylinder 11 'connecting the arm 5 and the gantry 3. The horizontal cylinder 1 can be reciprocally rotated about a shaft 6 in the horizontal direction. The horizontal driving device 11 is formed by 1'or a rotary actuator. The lifting platform 9 is connected to an upright cylinder 12 'provided at the tip 5 ", The upright cylinder 1 can be lifted up and down by being restrained by the units 8 and 8. The vertical driving device is formed by 2 '.

[0013]   The horizontal guide rail 2 is made of I-shaped steel as shown in FIG. The guide rollers 7, 7 are supported on both sides.

[0014]   Reference numeral 18 in the figure denotes a stopper of the horizontal rotation arm 5, 19 denotes a coil swing prevention arm, 20 is a cylinder for raising and lowering the prevention arm 19, 21 is the spiral 1 provided at the tip 5 ". 5 and 15 rotating hydraulic motors, and 22 a rotating sprocket for rotating the spirals 15 and 15. , 23 are turning chains.

[0015]

[Effect of device]

  Since the present invention is configured as described above, the transfer direction of the coil 13 is changed or the curve is transferred. Can be performed with one actuator, and the area for direction change is small, and the structure and mechanism are simple. Not only is the entire equipment compact, but positioning control and operation are simple. It can be carried out.
