Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a down-ender used to convey strip coils produced in rolling mills of steel mills by rotating the coils 90 times around a horizontal axis.

□Generally, a down-ender is provided with a horizontal support surface and a vertical support surface in an L-shaped frame, and is provided near an intersecting chain line that is orthogonal to both sides, and about an axis parallel to the intersecting chain line. The conveyor device rotates the coil placed on the horizontal support surface to overturn it onto the vertical support surface, and transfers the coil onto a trolley disposed adjacent to the downender.

When transferring the coil from the conveyor to the downender, it is necessary to stop the conveyor at 1r + the transfer position, but since a stopping error occurs in the conveyor, the coil either stops just before the vertical support surface of the downender, or Either it collides with the vertical support surface and stops.

If it stops in front of the vertical support surface, the coil will fall onto the vertical support surface due to its own weight while the downender is turning, and will collide with the vertical support surface.

In this case, damage will occur at the collision location of the coil.

Similar damage can also occur if a vertical support surface is struck directly from a conveyor.

Therefore, the present invention aims to prevent such damage to the coil, and one embodiment of the present invention will be described below with reference to the drawings.

The present invention is a down ender 3 in which a horizontal support stand 1 and a vertical support stand 2 are provided in an L-shape. A movable table 5 is provided which rises while moving, and the movement of the movable table 5 is performed by a drive device 7 connected via a compressive shock absorbing means 6.

To further explain this embodiment in detail, the horizontal support 1.1 consists of a pair of left and right arm-shaped frames, as shown in FIG. do.

Conveyors 8, 8 are intricately laid between the horizontal supports 1, 1.

The vertical support base 2 is composed of a pair of columnar support bases 2.2, the end faces of which serve as support surfaces 2a, 2a, which are perpendicular to the support surfaces of the horizontal support base, and Support surface 2a.

2a forms a V-shape in a plan view (FIG. 2).

The inclined guide 4 (FIG. 2, FIG. 4, and FIG. 5) has horizontal surfaces at both ends and an inclined surface in the middle. The wheel 5a is held between the wheels 5a.

In this embodiment, the driving device 7 connected to the movable table 5 uses a hydraulic cylinder, and as shown in FIG. A piston rod 7 is attached to a mounting member 5b pivotally attached to the tip of the stand.
A compressive shock absorbing means 6 is loosely fitted into the piston rod 7b so as to be able to slide within a certain range, and between the piston rod 7b and the mounting member 5b.
A barrel compression spring is attached.

Further, on the opposite side of the conveyor 8 with the main downender 3 in between, a cart 9 is placed guided by rails 10, as shown in FIGS. 1 and 2.

Next, the operation of the down ender 3 of the present invention will be explained.

First, as shown in FIGS. 1 and 2, when the cylindrical split coil 11 is conveyed by the conveyor 8 to just before the vertical support surface 2a of the downender 3, the coil 11 is notified that it has reached that point. The conveyor 8 is stopped by the signal from the detected sensor.

At this time, the top surface level of the conveyor 8 is arranged approximately 50 mm higher than the top surface level of the movable table 5 of the downender 3 in this embodiment.

Next, by pulling in the piston rod of the hydraulic cylinder that is the driving device 7, the movable table 5 is guided to the inclined guide 4 and raised.

Thereby, in this embodiment, the cylindrical end surface 11a of the split coil 11 is placed about 30 mm higher than the upper surface of the movable table 5 or the conveyor 8.

At this time, the compression spring serving as the compression shock absorbing means 6 has a set length.

Next, the hydraulic cylinder 12 for rotation is activated, and both support stands 1,
2 around the pivot axis, in this example, approximately l~
After turning about 10 degrees, the weight of the split coil 11 placed on the movable base 5 causes the movable base 5 to compress the compression spring 6 and move toward the vertical support base 2, causing the cylindrical surface of the split coil 11 to move toward the vertical support base 2. 11b is the support surface 2 of the vertical support base 2
It comes into contact with a and stops.

In this state, both support stands 1 and 2 can be rotated for about 9 hours.
A detector (not shown) detects the rotation by δ and stops the rotation.

Then, the split coil 11 is transferred to the trolley 9, and after the split coil 11 is conveyed, the mounting tables 1 and 2 are rotated in the opposite direction to the rotation direction.

Then, the hydraulic cylinder is operated to return the horizontal support base 1 to its original position.

In the above embodiment, the split coil 11 is connected to the conveyor 8.
Although the conveyor 8 is temporarily stopped when transferring the split coil 11 from the coil to the downender 3, there is no need to be limited thereto. 11 may be transferred.

As is clear from the above description, the present invention, when transferring the flip coil from the conveyor to the horizontal support stand of the downender, lifts the strip coil from the conveyor and brings it into contact with the vertical support stand surface of the downender without any gaps. The end surface of the strip coil is transferred without sliding contact with the top surface of the conveyor, so the end surface of the strip coil is not abraded by the top surface of the conveyor, and the driving device 7 is connected to the movable table 5 via the compression shock absorbing means 6. Therefore, when the downender turns, the split coil 11 moves and contacts the vertical support base 2 in a cushioning manner, and does not collide with the vertical support base 2 as in the conventional case, thereby preventing damage to the split coil due to collision. This has the effect of preventing damage to the outer periphery of the coil and cutting of the binding wire that binds the coil.

Note that the present invention is not limited to the above embodiments,
For example, the compression shock absorbing means 6 may use a shock absorbing air cylinder or the like instead of a compression spring.
