Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to pickling, heat treatment, cutting, molding, etc., before and after continuous unwinding from a coil, or
The present invention relates to a facility for changing the shape of a strip such as a short steel plate, for example, a roller table such as a looper facility or a sorting table facility.

[Prior Art] In a processing line for a coiled steel plate or the like, the shape before or after the unwinding process is changed, or the shape of a short strip is changed,
Alternatively, to change the flow direction, a swing table that raises and lowers a table having a constant shape is used.

FIG. 7 shows a looper facility equipped with a swing table.
Here is an example: The coiled strip is unwound and subjected to various treatments. At that time, a looper facility is attached for the purpose of releasing the tension of the strip and securing a length corresponding to welding time. Conventional looper equipment is No. 7
As shown in the figure, it is composed of entry-side tables 23a, 23b, threading table 21, and exit-side tables 23c, 23d. When passing the leading end of the strip 51a, the threading table 21 is raised by the drive cylinder 22, guided by the copying rollers 24a, 24b, and the entry / exit side table 23 is driven to form a horizontal table.
During steady running, the threading table 21 is lowered by the drive cylinder 22, guided by the copying rollers 24a and 24b, and the entry / exit side table 23 is driven to form a free loop 51b. When passing the trailing end of the strip, after pulling the strip up to the horizontal, raise the threading table 21 with the drive cylinder 22 as in the leading end, and guide it with the copying rollers 24a, 24b to follow the entry / exit side table 23. Form a horizontal table. Since there is a large difference between the shape of the table during operation and the shape of the free loop strip, these operations cannot be performed in the loop threaded state.

FIG. 8 shows a distribution table facility equipped with a swing table. In order to change the flow direction in order to change the flow direction in order to continuously or inductively guide a short plate in the distribution table facility, when the swing table 32a is raised by the drive cylinder 34, the strip can be removed. Is guided to the upper line and lowered (32
b), you will be guided to the lower line. At the time of switching to the lower side, since the swing table is a flat table, there is always a bending point at the connecting portion with the front table 31, which may affect the property of the strip or impair the smoothness of the threading. .

[Problems to be solved by the invention] With a swing table, there is an advantage in that the shape and flow can be changed only by a simple motion of swinging the table, but a continuous curved surface shape change during passage does not occur. It is possible. Also, in the looper equipment,
During steady operation, or from steady operation to the rear end threading,
It was impossible to carry the plate while holding the plate material on the table. Moreover, since the table is flat, there is a bending point at the connecting point of the table, which affects the properties of the strip material and hinders the smoothness of the strip.

Although there is a twin roll type strip caster rear surface table of Japanese Utility Model Laid-Open No. 63-111244 in the table of the continuous casting equipment, there is a problem that the shape of the table cannot be changed immediately with the configuration of only one fixed frame.

[Means for Solving the Problems] In order to solve the above problems, the present invention connects both sides of a plurality of table rolls with link plates, and installs table roll bearings on the outside or inside or both sides of the link plates. One or more lift frames for supporting the table roll bearings are provided, and one fixed frame for supporting the table roll bearings is provided below the lift frames. (EN) Provided is a freely-shaped roller table, each of which is formed in a shape corresponding to the shape of a passing plate, and one of which can be selected from a plurality of lifting frames.

A fixed frame or a lifting frame that supports the table roll bearing is installed below the lifting frame.
The configuration in which the table is provided means a state in which the elevating frame is raised as shown in FIG.

[Operation] Both sides of a plurality of table rolls are connected by link plates to form a flexible roller table such as a roller chain. By supporting this roller table with an elevating frame or a fixed frame, a roller table having a required shape can be formed. Furthermore, by providing multiple lifting frames and fixed frames,
A multi-shaped roller table can be arbitrarily selected according to the number. Similarly, by matching the table shape to the free loop strip shape, while holding the plate material,
It is possible to operate the table, and there is no bending point that occurs at the connecting portion of the table, and it is possible to smoothly pass the plate.

[Embodiment] Hereinafter, the features of the present invention will be specifically described with reference to the drawings. 1 to 6 show two examples of an embodiment in which a looper facility is constructed, and FIG. 9 shows an example in which a distribution table is constructed. First, an example in which the looper equipment is configured will be shown. The numbers in FIGS. 1 to 6 indicate the same numbers, and in the following description, the numbers in the same figure are used as appropriate. As shown in FIGS. 1 and 2, the embodiment of the looper equipment comprises an entrance side basket roll 13a, a central threading table 12 and an exit side basket roll 13b. The inlet and outlet basket rolls 13a, 13b are the freely-shaped table of the present invention. When passing the leading end of the strip 51a, the entry-side basket roll 13a, the central threading table 12, and the exit-side basket roll 13b are raised to form a horizontal table, and the table rolls smoothly thread without any bumps. The input / output basket rolls 13a, 13b extend the elevating cylinders 11a, 11b, hold the elevating frame 2, and hold the table rolls 3a-3g.
Bearings 4a to 4f fixed to the link plates 9a to 9c and 10a to 10c connecting the
It is supported by 6a-6f and forms a horizontal table. Bearing 4
Consists of a cylinder with a plurality of (two in FIG. 4) trapezoidal grooves that engage with a seat 5.6 to fix the position of the table roll and a link mounting flange.

The roller table of the present invention can be driven by a roll, and the driving sprocket for each table roll 3 is shown in FIG.
Indicates 7,8.

When the threading of the tip end is completed, the entrance side basket roll 13a, the central threading table 12, and the exit side basket roll 13b are lowered while passing the thread to form a loop 51b.
The operation of the inlet and outlet basket rolls 13a and 13b is shown. When the lifting cylinders 11a and 11b are contracted, the lifting frame 2 is lowered and the entire table rolls 3a to 3g are lowered.
First, the bearing 4 fixed to the link plate 10a connecting the table rolls 3a to 3b is fixed from the receiving seat 6a fixed to the elevating frame 2 to the receiving seat 5a fixed to the fixed frame 1.
Transfer to. Only the table roll 3g is fixed, and only a part is formed in an arc shape, and the rest is a flat table. In the same manner, as shown in FIG. 6, the next table rolls 3b to 3f successively descend while changing their shapes to finally form an arc table.

In addition, in FIG. 6, the central threading table is also included.
It descends according to the exit basket roll to form a multi-shaped continuous table. In addition, as shown in FIG. 5, the central threaded table 12 swings the table 12a, descends, and retreats from the loop-shaped strip.

During steady operation, the strip is controlled by front and rear equipment so as to form a constant loop, but it is not described because it is not relevant to the present invention.

When the steady threading is completed, the loop is pulled up to gradually raise the entrance-side basket roll 13a, the central threading table 12, and the exit-side basket roll 13b to form a curved table while holding the strip, and the trailing end Wait for the board. Contrary to the above, the operation of the input and output basket rolls 13a and 13b is reversed.When the elevating cylinders 11a and 11b are extended, the elevating frame rises, and the link plate 9c that first connects the table rolls 3f to 3g is first. The bearing 4f, which is fixed to, moves from the receiving seat 5f fixed to the fixed frame to the receiving seat 6f fixed to the lifting frame.

Only table roll 3g goes up and down, and only a part is flat shape,
An arcuate table is formed on the remaining portion. In the same manner, as shown in FIG. 6, the next table rolls 3b to 3f continuously rise while changing their shapes to finally form a horizontal table. That is, the inlet and outlet basket rolls continuously change their shapes according to the frame shape into two shapes, a plane and an arc, to form a roller table.

Next, FIG. 9 shows an embodiment in which a distribution table is constructed. To change the flow direction in order to guide a continuous or short plate in the distribution table equipment, the full table 31
When the strip arrives, the drive cylinder 34 raises the free-form table 33a of the present invention so that the strip is guided to the upper line, and when it is lowered (33b), the strip is guided to the lower line. When switching between the upper and lower lines, the table of the lifting / fixing frame is formed into a required curved surface so that the influence on the strip can be reduced and the transfer between the tables can be smoothly performed.

In addition, in FIG. 9, although one lifting frame has been described,
It is also possible to increase the number of distribution positions by using two or more lifting frames.

For example, FIGS. 10 and 11 show an example of a table in which two lifting frames are provided and can be sorted in three directions. As shown in the figure, the lower fixed frame 1 is the same as that shown in FIG. 9, and the two lifting frames 2A and 2B can be housed inside the frame 1, and the predetermined strips are respectively driven by the drive cylinders 34A and 34B. It is possible to climb to the running line. One elevating frame 2A has a curved surface symmetrical to the lower line for the upper line, and the other elevating frame 2B has a linear shape for the intermediate line. The strip is distributed to a desired line by appropriately switching the line.
Of course, it is also possible to add three lifting frames or more to the inside of the fixed frame and further increase the number of distributions.

FIG. 11 shows a table roll bearing part when two lifting frames are adopted, and three trapezoidal grooves are formed in the bearing 4, and the receiving seat 5 of the fixed frame 1 is formed in these grooves.
The receiving seats 6A and 6B on the elevating frame side are adapted to mesh with each other. The receiving seats 6A and 6B on the lifting frame side are attached to the lifting frames 2A and 2B, respectively, and vertically move independently. Therefore, when actually moving up and down each lifting frame, the lifting frame does not interfere with the fixed frame, and
It is necessary to have a structure in which the two lifting frames do not interfere with each other.

[Effects of the Invention] As described above, according to the present invention, it is possible to continuously form a multi-shaped table in a threaded state, the table shape is raised and lowered, and the shape of the fixed frame is determined. , It can be arbitrarily selected by selecting the shape in the middle of change. As a result, it is possible to operate the table during operation and hold the strip on the table not only at the leading edge but also at the trailing edge. Also, select appropriate lifting and fixing frame shapes,
By selecting the shape in the middle of change, it is possible to smoothly pass the plate without bending points at the connecting portion of the table, with little influence on the property of the strip. In addition, with the conventional looper equipment, it is difficult to drive the table roll due to its structure, and there is a problem that the strip is scratched or the like. In the table of the present invention, the fixed roll portion is connected to the front and rear drives,
By connecting each roll with a chain, it is possible to drive the roll in synchronization with the line.
