Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for inverting heavy objects such as slabs.

For descaling, inspection, etc. of the slab, it becomes necessary to turn it over during transportation.

Conventionally, this reversal has been commonly performed using a rotating arm, but this method requires strong rotational power and a large amount of planar space.

Therefore, the inventors of the present invention first developed a device that lifts both ends of a slab with a chino, sends this chino, and flips the slab in the air (Japanese Patent Application No. 50-70542, 146062) Patent application 1972-94230 (
JP 53-20260)).

This reversing device has an excellent effect that completely eliminates the drawbacks of the conventional device mentioned above, but when the slabs are fed in such a way that their lengths cross the conveyor line, sagging occurs. Since the lowered cheno gets in the way of moving the slab, the above-mentioned reversing device cannot be used as is, and many improvements are required.

In addition, slabs of considerably different lengths may randomly flow, and a reversing device that can handle this is also required.

The present invention has been made to solve the above problems.

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

As shown in FIGS. 1 to 3, the slab A is conveyed by the chain conveyor 10 so that its long side is perpendicular to the direction of movement.

At the stop position of the slab A, the reversing device of the present invention is installed.

As shown in the figure, a pair of frames 20 and 20' are fixed at a constant interval so as to cross above the conveyor chain conveyor 10, and the rails 20 and 20' on the upper surface of the frame
1 and 21', movable girders 22 and 22' are attached.

These girders 22, 22' are connected to motors 23, 23, respectively.
Run by '.

Approximately in the center of the girder 23 is provided a longitudinally extending opening 24, on both sides of which guide rails 25.25 are fixed.

Furthermore, a pair of wheels 26.26 each having a sprocket 27 attached to the axle is mounted on the guide rail 25.25, and each axle is connected to a piston shaft 29 of a cylinder 28 attached to the upper surface of the girder 22. 28
．． The movement of 28 causes the wheels 26, 26 and thus the sprockets 27.degree. 27 to move toward or away from each other.

Further, a support 30 is fixed to the girder 22 so as not to impede movement of the wheel 26.
Sprockets 32 are attached to both ends of the rod 31 supported by the
．． 32 is attached (Fig. 2).

These sprockets 32, 32 and said sprocket 1
-27. Endless chains 733, 33 are hung through the opening 24 and hang down from the opening 24 below the girder 22. The chess 7 which are received and hanging down are held at a constant interval, that is, at an interval wider than the width of the slab A.

The support material 34 is connected to the girder 22 using only the ropes 35, 35.
If necessary, the cylinder 36.
36, and by the action of the cylinder, the support member 34 may be raised so that the check 733 can be lifted.

The reason for this will be explained later.

The check 733 is adapted to be fed in one direction by a suitable drive means 37 (FIG. 1) that drives the sprocket 32.

Of course, the feeding direction can be either forward or reverse.

Further, a means for adjusting the feed amount may be provided.

The mechanism attached to one girder 22 is as described above, but the other girder 22' is also provided with a completely similar mechanism.

Next, the action will be explained.

Now, as shown by the chain line in Figure 1, the frame 20.20
′, when slab A stops at the intermediate portion of motor 23.
23' is rotated to move the girders 22 and 22' toward each other.

At this time, the bridge members 34 and 34' are connected to the chain conveyor 10.
By the operation of cylinder 36, 36', so as not to hit the
As shown by the chain line in FIG. 3, once the receiver lifts the material 34, 34', and while the girders 22, 22' are moving, an appropriate detector detects that it has approached the end of the slab A, and then the cylinder is moved again. 36. By operating 36', the receiver is material 34,
34' is lowered below the slab A, and when the girders 22, 22' are located a certain distance inward from the end thereof, the girders 22, 22' are stopped (see the solid line in FIG. 3).

Incidentally, if the size of the slab A is always constant and the positional relationship with respect to the chain conveyor 10 is always constant (the position does not shift laterally), the operation of the cylinders 36 and 36' can be performed without providing the above-mentioned detector. timing and girder 22,
The stop position of 22' can be controlled.

Further, the method of inserting the receiving members 34 and 34' under the slab A is not necessarily limited to the above method.

Other methods will be described later. Now, by the above operation, when the members 34, 34' of the chees 733, 33' are located below the end of the slab A, the loops of the chees 733, 33' hanging down as shown in FIG. The end of slab A is now inserted inside.

Therefore, as shown in Fig. 2, when the cylinders 28, 28 (and the cylinders on the girder 22I (not shown) are operated and the sprockets 27, 27 approach each other as shown by the chain lines in the figure), the sprockets move inward. Cheer as much as you do 7
33 has been rolled up, and slab A is lifted.

At this time, the check 733 is narrowed toward the center, so that the slab A can be lifted in a stable state.

Note that this aperture width is preferably smaller than the thickness of slab A.

Next, when the drive means 37 rotates the sprocket 32 and sends the chino 33 in one direction, the slab A is reversed.

At this time, if the aperture width of the cheno 33 is made smaller than the thickness of the slab A (see the two-dot chain line in Fig. 2), the slab A will not fall onto the chino 33 during reversal, and therefore the reversal impact will be reduced. It can be flipped smoothly without any problems.

After the reversal is completed, operate the cylinders 28 and 28 again,
When the sprockets 27, 27 are separated, the slab A is lowered and placed on the chain conveyor 10.

The chino 33 that has further descended is supported by the support member 34.

Thereupon, the girder 22 is moved and the receiver material 34 is removed from the end of the slab A to the outside.

Needless to say, the above operations are also performed synchronously in the girder 22'.

In addition, in the above example, sprockets 27 and 27
Although the approach and separation of the two is performed by the operation of the cylinder, it can also be performed by other means, such as rotation of the screw shaft.

It is also possible to add means for detecting whether the slab has been completely reversed.

Figures 4 to 6 show that the holder of the chino 33, 33' is made of material 34.
．． 34' is shown on the underside of the end of slab A.

As shown in FIG. 4, a cylinder 40 is disposed upward between the chain conveyors 10, and a support is mounted on the tip of the piston shaft.
1 is fixed and slab A stopped at a predetermined position is lifted as shown by the chain line by the action of the cylinder, and then the girder 2
2 and 22' are moved, and the receivers 34 and 34' are positioned on the lower surface of the end of slab A as shown by the chain line.

In this case, the cylinder 36, 36' is omitted and the wire 34, 34' is not required to move up and down.
5.35' can be directly connected to the girder.

As shown in FIGS. 5 and 6, the receiver may be adapted to pull down a portion of the chain conveyor 10 that impedes movement of the material 34, 34'.

As shown in the figure, the stand 42 of the chain conveyor at the stop position of the slab A is fixed to the tip of the piston shaft of the cylinder 43, and the movement of the cylinder 43 causes the stand 42 to move up and down, and the stand 42 moves up and down, and the chain conveyor moves up and down accordingly. A part of the conveyor 10 is pulled down as shown by the chain line in FIG.

However, in such a movable receiver, a fixed support base 44 whose level is slightly lower than the conveying surface is arranged between the bases 42, so that the slab A is supported at almost the original level.

Therefore, the chain conveyor 10 does not get in the way, and the chain conveyor 10
3 allows the material 34 to be inserted into the bottom surface of the end of the slab A.

FIG. 7 shows that the holding receiver of the chino 33 is attached to the slab A.
Detecting means is shown for stopping at a position a predetermined distance inside from the end of.

As shown in the figure, the bent part of the bending part 45 is pivoted on the outside of the support member 34, and a switch 46 operated by the lower end of this rod 45 is fixed to the support member 34.

Note that the rod 45 is deflected counterclockwise in the figure by a spring 47.

Now, as the girder 22 moves, the wire 35
When the material 34 approaches one end of slab A, the upper end of 845 hits the end of slab A, and as shown by the chain line in the figure, the material 34 moves inwards. When moved, rod 45 rotates about its pivot and presses switch 46 at its lower end.

When the girder 22 is stopped by this signal, the support member 34 is stopped at a position a predetermined distance inside from one end of the slab A.

This distance can be appropriately set depending on the bending angle of the bale 45, the length of the rod from the bending part, the position of the switch 46, etc.

In addition to the above, it is also possible to detect one end of the slab using a photocell, a proximity switch, etc., operate a counter using this signal, and stop the girder 22 when the count reaches a count corresponding to the distance. .

According to the reversing device of the present invention, as described above, since the weight of a heavy object is used to reverse it in the air, a large amount of power is not required, and there is no reversal impact, and the reversal can be smoothly performed. The work is safe and does not cause any damage to the
Since it can be reversed on the conveyance line, it has the advantage that it does not take up much planar space.

Furthermore, even if the dimensions of the heavy object are different, it can be turned over without any problem.

In addition, heavy objects can be lifted in a stable manner through the squeezing action of the cheno, and since the cheno is always aligned with at least one side of the heavy object even during inversion, the object can be inverted in a stable manner. It has great advantages.
