Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a so-called down-end at a time in a state where a plurality of coils are superimposed on a packing line for packing a coiled steel coil. The present invention relates to a device that turns 90 degrees from a state to an up-end state.

[Conventional technology]

Conventionally, the work of turning a steel sheet coil from the down end to the up end and stacking a plurality of coils is carried out by lifting with a lifting machine such as an overhead crane and mounting it on a turning device.
After turning, the operator repeatedly lifts it with a lifting machine and mounts it on a skid, etc., by repeating the process multiple times, and none of the processes was automated.

In recent years, various factories such as steelworks have been examining ways to realize an unmanned factory by automating various operations. However, in a packing line that transports and packs steel sheet coils in steelworks, various types of workers are required. It is the fact that the work is performed while operating the machine.

In such a situation, a single device automatically performs the work of turning the steel coil, the work of stacking multiple pieces on a skid, etc., and the work of transporting it to a transport conveyor, which were previously performed by the operator's mechanical operation. This will advance the automation of the packaging equipment line and eliminate the need for operators to perform mechanical operations, etc., thereby improving the safety of the work and reducing wasted time and labor such as hanging steel coil to increase the equipment capacity. There has been a strong demand for the appearance of a device that can be used. With the advent of such devices, multiple processes can be performed with one device.
It is evident that the equipment cost can be reduced as compared with the well-known equipment plan, and that it does not require a large amount of equipment space, which is advantageous in terms of the equipment investment effect.

Examples of the prior art relating to the present invention include, for example, Japanese Utility Model Publication No. Sho 51-31792, Japanese Utility Model Publication No. Sho 53-46322, and Japanese Utility Model Publication No. Sho 51-29880.
And the inventions and devices disclosed in JP-B-61-2564.

However, the inventions and devices described in these publications have a configuration in which individual coils are turned up-end and then superimposed by another device. Absent.

The present invention has been made in view of the above points, and has been conventionally performed by a worker, in which a step of turning a steel sheet coil from a down-end state to an up-end state, a step of stacking a plurality of coils on a ski, and further an up-step. It is an object of the present invention to provide an apparatus capable of automatically performing a step of carrying out a steel coil in an end state together with a skid.

[Means for solving the problem]

For this purpose, the cart 1, the first frame 2, the holder
The third and fourth frames 4 were the main constituent requirements.

The bogie 1 holds a coil C in a down-end posture with its inner diameter, and assembles a holding piece 6 that can move up and down, and travels freely in the front-rear direction. The first frame 2 is opposed to the carriage 1 and rotates 90 degrees to a horizontal posture and an upright posture. The holder 3 is mounted on the first frame 2 to support and receive the coil C from the holding piece 6 at its inner diameter, and is also capable of extending and contracting in the axial direction of the coil C and having a horizontal posture. At least 180 degrees in the horizontal plane.

The second frame 4 has the same rotating shaft 7 as the first frame 2.
When the coil C is turned to the up-end position, the coil C is turned to the upright position, and is positioned close to and opposed to the coil, and is rotated in the same direction in synchronization with the first frame 2 in the horizontal position. It is set to be horizontal.

In a horizontal position, the skid S on which the coil is mounted is removably mounted, and the roller table 5 connected to the coil conveyor can be mounted on the second frame 4.

[Action]

 The operation of the present invention will be described with reference to the drawings.

First, as shown in FIG. 2, the coil C in the down-end posture is transported by a carrier (not shown) or the like, and is held by the holding piece 6 of the carriage 1.

Next, as shown in FIG. 3, the carriage 1 travels toward the holder 3 and transfers the coil C of the holding piece 6 to the holder 3 in the down-end posture. At this time, since the holding piece 6 is set to be able to move up and down, the coil C can be easily transferred to the holder 3 by moving up and down. That is, the coil C is held in a state in which the inner diameter portion supported by the holder 3 is at a position higher than the holder 3, and the coil 3 travels until the holder 3 enters the support position within the inner diameter of the coil C. The coil C is transferred to the holder 3 by descending.

The carriage 1 returns to the original position after transferring the coil C to the holder 3, receives a new coil C again, travels, and transfers the coil C to the holder 3. By repeating this operation a plurality of times, a plurality of coils C are held by the holder 3 as shown in FIG.

Since the holder 3 can be extended and contracted in the front-rear direction, its length can be freely set in accordance with the number and width of the coils C and the spacers inserted between the coils C, so that the desired number of coils C Can be held.

When the plurality of coils C are transferred to the holder 3, the holder 3 turns 180 degrees in a horizontal plane as shown in FIG. Then, as shown in FIG. 5, the second frame 4 which has been in the horizontal posture is rotated 90 degrees to be in the upright posture. Thereafter, the upper surface of the second frame 4 is brought into contact with the end surface of the coil C by the expansion and contraction of the holder 3. This is because the upper surface of the second frame 4 and the coil C
And the coil C
This is because the coil C can be turned in a stable posture without being mounted on the second frame 4 in a falling state at the time of turning. When a roller table on which a skid is detachably mounted is assembled on the second frame 4, the upper surface of the skid S and the end surface of the coil C are brought into contact for the above-mentioned reason.

From this state, as shown in FIG.
The second frame 4 is rotated 90 degrees in the same direction in synchronization with the first frame 2 so as to be in the upright posture and the second frame 4 is in the horizontal posture. As a result, the coil C is turned to the up-end state. Then, as shown in FIG. 7, the holder 3 is contracted and detached from the coil C.

When the roller table 5 on which the skid is mounted is assembled to the second frame 4, the skid S is detached from the roller table 5, the roller table 5 is driven, and the coil C is transported together with the skid S to the conveyor. is there.

After the transfer of the coil C, as shown in FIG. 8, the first frame 2 is rotated 90 degrees in the reverse direction to return to the original horizontal posture. At this time, the first frame 2 is not rotated in synchronization with the second frame 4 and is kept in a horizontal posture. Then, the holder 3 is turned in the horizontal plane by 180 degrees, and as shown in FIG. 2, the holder 3 is returned to the initial state, and the above operation is repeated.
