Description

Detailed Description of the Invention [Industrial Field of Application] The present invention is applicable to turning a steel sheet coil wound into a coil shape by 90 degrees from a so-called down-end state to an up-end state, and directly transferring it to a conveyor. This relates to equipment that can be transferred to the top.

[Conventional technology]

Conventionally, the work of turning a coil from the down end to the up end generally requires a lifting machine such as an overhead crane, a device to turn the coil 90 degrees, and a lifting device to mount the up end coil on a skid. This is done by operators.

Currently, it is not yet automated.

In recent years, studies have been actively conducted to automate various tasks in all kinds of factories, such as steel mills, to make them unmanned. In the packaging line that transports and packs FJ board co-coils at steel plants, the coils are transported by conveyors, etc., and various packaging tasks are performed by workers and machines, but there are various proposals for automation in this packaging line as well. being done.

As mentioned above, it has been difficult to perform the work of turning the steel plate coil 90 degrees from the down end to the up end and mounting it on the skid in this packaging line etc. as one continuous work.

For example, after a steel plate coil is rotated by a device that rotates 90 degrees, the coil is hung and mounted on a fixed skid using an overhead crane or the like.

In these conventional packaging lines, a lifting machine equipped with a dedicated lifting device to lift the down-end coil and the up-end coil, respectively. II plate coil turning device,
Automation of packaging lines in combination with skid supply devices, etc. is being considered.

However, the current situation is that it is difficult to predict the clear effects of capital investment, and the reality is that this line has not yet been automated.

Under these circumstances, the process of turning the 2w4 plate coil from the down end to the up end, and the process of mounting the up ended coil on the skid.

And by automatically accomplishing the process of transferring the coil to the conveyor, etc. with one device.

It is desirable to advance the automation of packaging lines.

This allows the two tasks to be carried out safely.

Wasteful processes such as rehanging steel plate coils can be reduced and equipment capacity can be increased. or.

By performing several types of work in one device, equipment costs can be reduced compared to conventional equipment or conventional equipment plans, and the equipment space can be reduced, which is advantageous in terms of equipment investment efficiency.

Many inventions and ideas have been made to equip such better devices. For example, Utility Model Publication No. 51-31792, Utility Model Number 51-29880, and Special Publication Number 61-25.
This is what is shown in Publication No. 64.

[Problem to be solved by the invention]

However, what these conventional techniques have in common is that in the devices for turning the coil, two pedestals are fixedly assembled in an L-shape at right angles. Therefore, for example, when loading a coil from a lifting machine onto a horizontally positioned pedestal, the other upright pedestal gets in the way, making the operation time-consuming. In particular, this is a serious problem when automatically mounting a coil.

In order to solve this problem, it is conceivable to lengthen the horizontal pedestal so that the upright pedestal does not get in the way when the coil is mounted. but.

Then, when turning the coil, it is necessary to slide the coil on the horizontal pedestal over a long distance.

In order to slide a long distance, the already well-known simple mechanism shown in the above-mentioned Japanese Utility Model Publication No. 51-31792, which uses springs to catch the natural slide, is insufficient, and therefore a dedicated mechanism is required. , the entire device becomes even larger, resulting in disadvantages such as a waste of equipment space.

The present invention was devised in view of these problems.

A process that makes it easy to install the coil and turns the steel plate coil from the down end to the up end.

By automatically accomplishing the process of loading the up-ended coil onto the skid and the process of transferring the coil to the conveyor with one device, we aim to achieve more advanced automation of packaging and other lines. purpose.

[Means to solve the problem]

As a means for this purpose, there is a first frame 1 which can be freely rotated between a horizontal position and an upright position, and which is slidably assembled onto the first frame 1, so that when the coil C is mounted in a down-end position, the first frame 1 can be freely rotated between a horizontal position and an upright position. a second frame 2 which is rotatable between a horizontal position and an upright position on the same rotation axis 7 as the first frame 1; It consists of a skid S that is detachably assembled and a roller table 4 that is continuous with the conveyor belt for conveying the coils.

Then, when the coil C is rotated, after the second frame 2 is placed in an upright position, the second frame 2 and the first frame 1 are
It was decided that they would rotate in the same direction in mutual postures.

Incidentally, the coil holder 3 can be attached to the first frame 1 so as to be movable up and down.

Moreover, the rotation of the first frame 1 and the second frame 2 can be achieved by a cylinder.

[Effect]

The operation of the present invention will be explained with reference to FIG.

First, as shown in Fig. 2, after the first frame 1 and the second frame 2 are placed in a horizontal position by the action of the cylinder, the rope plate coil C is received by a lifting machine (not shown) in a down-end state. At the same time as being mounted on the stand 3, the skid S is also mounted on the roller table 4. This skid S is positioned at a fixed position and is detachably mounted. When the coil C described above is installed, not only the first frame 1 but also the second frame 2 are in a horizontal position,
Since it is not upright unlike the prior art, it does not interfere with the mounting work, and therefore the coil C can be mounted extremely easily.

Next, as shown in FIG. 3, the second frame 2 is rotated by the action of the cylinder and assumes an upright position.

Accordingly, the roller table 4 and skid S also stand upright. After the second frame 2 is erected, the coil holder 3
The coil C is moved up and down according to the outer diameter of the steel plate coil C.
is set to be located at the center of the skid S.

Then, as shown in FIG. 4, the first frame 1 and the second frame 2, which are 90 degrees apart from each other, are simultaneously rotated 90 degrees in the same direction. by this.

The coil holder 3, which was in a horizontal position, is tilted, and due to the tilt, the coil C moves toward the roller table 4 by its own weight. At this time, since the coil pedestal 3 is slidable, the coil C moves together with the coil pedestal 3, and thus the movement is achieved smoothly. When the rotation of the first frame 1 and the second frame 2 is completed, the coil C is mounted on the skid S in a horizontal position in an up-end state. As a result, the coil C, which has been turned to the up-end position as in the past, is lifted up and the skid S
The process of mounting it on top can be omitted.

Next, after separating the coil C from the coil C by moving the coil pedestal 3 backward, the coil C is sent to the conveyor together with the skid S. At this time, since the roller table 4 is in a continuous position with the conveyor, the coil transfer car The coil C can be easily transferred onto the conveyor without the need for the following.

〔Example〕

An embodiment of the present invention is shown in FIGS. 1 to 5.

This device is installed in the middle of the packaging line, and a lifting machine for the down-end coil C is installed on the upstream side of the device, and a conveyor connected to the roller table 4 is installed on the downstream side to continuously process the packaging line. It has been made possible.

Of course, the device of the present invention is not limited to use on packaging lines.

It can also be adapted for use in other processes.

The first frame 1 has a substantially doglegged shape that is bent at approximately the middle thereof, and the middle portion thereof is fixed by a rotating shaft 7. The lower end of the first frame 1 is pivotally connected by a first cylinder 5, and when this first cylinder is driven, the 9
Rotate 0 degrees. An elevating cylinder 8 is attached to the upper part of the first frame l, and the elevating cylinder 8 is connected to a support stand 10 that supports the coil holder 3. Therefore, as the lifting cylinder 8 moves up and down, the coil pedestal 3 moves up and down. Further, in order to stabilize the vertical movement of the coil holder 3, two guide bars 9 are provided between the support 10 and the first frame l.

As shown in FIG. 5, the coil holder 3 has an upper end surface, which is the mounting portion, set in a V-shaped cross section, and the mounted coil C
In addition to being able to hold the coil C in a stable state, a mounting piece 14 made of a bullet material is provided on its upper end surface to prevent the coil C from slipping off and protect its surface. Also, a pair of wheels 12 are fixed to the front and rear of the coil holder 3, and the wheels 12 are run on the rails 13 of the support 10.

The coil holder 3 is slidable with respect to the support 10. Furthermore, the end face of the coil holder 3 and the support holder 1O are connected by a spring 11, and thereby the coil C
(Coil holder 3) is prevented from turning suddenly, and after coil C turns, it returns to its original position due to elasticity, providing a constant coil mounting position.

The second frame 2 has a substantially inverted dogleg shape that is bent at its lower part, and is provided in two ways sandwiching the first frame 1, and the lower part of each is rotated by the same rotation axis 7 as the first frame 1. It is freely pivoted. The lower end portion of each second frame 2 is pivoted by a separate second cylinder 6, and is rotated from a horizontal position to a vertical position by driving the second cylinder 6.

The second cylinder 6 is fixedly assembled to the first frame 1 via the cylinder holder 15, and therefore the second frame 2
The rotation from the vertical position to the horizontal position is.

This is achieved by the action of the first cylinder 5.

That is, the rotation of the second cylinder 2 from the horizontal position (FIG. 2) to the upright position (FIG. 3) is achieved by the rod of the second cylinder 2 extending.

When rotating from an upright position (Fig. 3) to a horizontal position (Fig. 4), the rod of the second cylinder 2 remains extended, and the rod of the first cylinder 1 contracts to move the first frame 1. They are rotated simultaneously in the same direction by transmitting the force of rotation. Of course, the present invention is not limited to this configuration.

For example, the horizontal posture of the second frame 2 may be obtained by another cylinder or another mechanism.

The roller table 4 attached to the upper end of the second frame 2 is composed of a plurality of rollers arranged in parallel.The skid S is attached to the upper surface of the table 4 with claws on both sides for easy attachment and detachment. are doing.

Note that the means for removably assembling the skid S is not particularly limited. Also, this skid S is automatically conveyed by a skid supply device and directly delivered to the roller table 4.
It may be assembled onto the top, or it may be pushed in with a pusher or the like so that it can be attached and detached.

〔Effect of the invention〕

In this way, in the coil turning device of the present invention, both frames are set in a horizontal position as much as possible when the coil is mounted.
This solves the problem of the conventional upright frame interfering with mounting work.

Work can be done more efficiently.

In addition, the skid was removably assembled on the roller table in advance, and the coil was turned and mounted on it in an up-end position, so unlike the conventional method, the coil that had been turned up-end was lifted up again and placed on the skid. This eliminates the process of mounting the device on top, which also improves work efficiency and safety.

Furthermore, since the roller table is set to be continuous with the conveyor in a horizontal position, it is possible to extremely easily move the coil that has been turned to the up-end onto the conveyor and convey it.

Therefore, there is no need for a conventional coil transfer vehicle, etc., and the efficiency of two operations is significantly improved.

The present invention not only allows the frame to not get in the way when mounting the coil, but also allows the process of turning the coil, mounting the turned coil onto the skid, and transferring the coil on the skid to the conveyor with great ease. This process can be accomplished with a single device, and it exhibits novel and excellent effects not found in conventional technology. the result.

For example, when packing ta-board cocoil and shipping it to a customer.

It becomes possible to automate the work of putting the product in an up-end state and placing it on a skid for packaging, which can bring great benefits such as improved processing capacity and safety.
