Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for transporting plate materials, particularly plate materials continuously produced in a continuous casting machine (hereinafter referred to as a continuous casting machine) to the next process (rolling, etc.). The present invention relates to a device for winding a plate material into a coil shape.

[Conventional technology]

After casting the plate material, the method of winding the slab into a coil to utilize sensible heat, and then supplying it to the next process of hot rolling, has been developed from the viewpoint of energy saving, as seen in Japanese Patent Application Laid-Open No. 133803/1983. This is something that is highly desired in the industry.

The specifications for such slab plate materials are plate thickness 20 to 40 mm,
The board width is 700 to 1,600 mm, and the temperature of the board is approximately 950 to 1,100°C. The inner diameter of the coil is
It is necessary to wind it to 600 to 700 mm and an outer diameter of 2000 to 2500 mm. In the example of the above-mentioned application, in order to prevent the inner diameter part of the coil from cooling too much during winding of the coil, a winding method without a mandle for supporting the inner diameter part (Utility Model Publication No. 47 -
34762) is used.

[Problem that the invention seeks to solve]

However, with this method, as the outer diameter of the formed coil increases, the support of the coil becomes unstable and it is difficult to wind it to a very large outer diameter.For a coil with an inner diameter of 600 to 700 mm, it is difficult to wind it to an outer diameter of about 1500 mm. was the limit.

SUMMARY OF THE INVENTION An object of the present invention is to provide a winding device capable of winding continuously cast slab material into a large-diameter coil using an up-coiler method.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention includes a bending roller that bends the continuously supplied plate material upward, and a bending roller that is provided above the bending roller while winding the curved plate material. In a plate material winding device equipped with a plurality of support rollers that support the coil at multiple points in contact with the lower side of the outer circumferential surface of the produced coil, the rear end side of the plurality of support rollers in the direction in which the plate material enters the coil. The supported roller is formed so that the position of its support point can be moved in the direction of increasing diameter of the coil as the diameter of the coil increases as the coil is wound.

[Effect]

In the present invention, the continuously supplied plate material is bent upward by bending rollers to form a coil.As the coil diameter increases, the position of the coil support mechanism consisting of support rollers is changed. Among the support rollers, the support roller located on the rear end side in the direction in which the plate material enters is made to have a different supporting position for the coil when the diameter is small and a position when the coil is large. While moving from the position to the large-diameter coil supporting position, the plate material is wound into a large-diameter coil.

〔Example〕

Next, a preferred embodiment of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 1 shows a principle diagram of winding a large diameter coil according to the present invention.

The plate material 1 is conveyed by guide rollers 23, 24, 25, and three bending rollers 11, 12,
It is bent by a bending mechanism consisting of 13,
It is bent as shown by the semicircular solid line 2 and hits the coil support roller 15. Thereafter, when the plate bent by the bending rollers 11 to 13 is further pushed in, the plate material 1 is pushed through the position shown by the one-dot chain line 3, and the coil 4 is formed. The center of this initial coil 4 is indicated by B. This initial coil 4 is supported by small diameter coil support rollers 14 and 15. The coil becomes even larger, and a coil 6 is formed by pushing the plate material 1 as indicated by a two-dot chain line 5. The inner diameter of this coil 6 is indicated by a two-dot chain line 7, and the center of the coil is indicated by C, but in this embodiment, this center C is located on the center of the coil support roller 15,
If the coil diameter becomes larger than this, the coil will fall to the left side in this figure and cannot be wound stably.

Therefore, in the present invention, one additional coil support roller 16 is provided. This support roller 16
Initially, the cylinder 21 supported by the base 22 is pushed up via the pin 20 with its center at the position Y' and kept on standby. If the coil 6 becomes even larger, the cylinder 21 is successively lowered to the position of the center Y of the support roller 16, and the plate material indicated by the three-dot chain line 8 is pushed in to create a larger diameter coil 9. . The center of this large diameter coil 9 is indicated by D, and the inner diameter is indicated by a three-dot chain line 10.

As described above, from the initial small diameter coil 4 to the large diameter coil 9, the three coil support rollers 14, 15, 1
A large diameter coil 9 is created by sequentially moving the support position in step 6.

That is, when the coil is small, it is supported by two coil support rollers 14 and 15, and when it becomes a large diameter coil, it is supported by two coil support rollers 15 and 16. Of these, the support roller 15 is commonly used to support both the small diameter coil and the large diameter coil.

Note that the guide 18 has the role of guiding the tip A of the plate when creating the initial coil 4 from the curved plate 2 having a semicircular diameter.

Further, the coil support roller 16 is connected to the support roller 1
attached to an arm 17 that rotates around 5,
The arm 17 is reinforced with a guide plate 19.

Adjustment of the amount of rolling of the bending rollers 11 and 12 with respect to the roller 13 is performed by raising and lowering the screw 33 by rotating a worm 32 and a worm wheel 34 contained in the box 31. For this reason, bending rollers 11 and 12
is attached to arm 28 which is supported by bracket 36. This arm 28 is operated by a cylinder 29 supported by a bracket 30 applying force to the connection point of the arm 28 via a pin 26 so that it can be opened and closed quickly when the plate material 1 is caught in or when the plate material 1 slips out. In addition, in FIG. 1, the rotation direction of each roller is indicated with an arrow.

FIG. 2 shows an example in which the system shown in FIG. 1 is actually implemented.
The main bending roller 13 and the coil support rollers 14 and 15 are supported by a common bearing box 51. The pedestal 42 supports the bearing box 51, an arm support bracket 36 that supports the two bending rollers, a worm mechanism that slightly raises and lowers the arm, the box 31, and the like. base 43
supports the cylinders 21, 29, etc.

Further, the wound large-diameter coil 9 is transported to another location by a hanger mechanism running on a separately provided pedestal 45, and then the next coil is wound.

The hanger mechanism lifts the large-diameter coil 9 by a hanger 44 that moves up and down in the direction of arrow E using a cylinder 48, and transports the large-diameter coil 9 by moving a cart 46, wheels 47, and a pedestal on which the hanger mechanism is loaded in the direction of arrow F. leave.

FIG. 3 shows a plan view of the coil support portion of FIG. 2. The coil support roller 16 is configured to be vertically movable around the coil support roller 15 by an arm 17. Each roller has 6 bearings on the arm
1,60. Further, each bending roller, each coil support roller, etc. are driven by spindles 67, 68, 69, and 70. Illustrations of the distribution gear box, motor, etc. that drive these spindles 67 to 70 are omitted.

The worm 32 that slightly raises and lowers the arm 28 is
A motor 66 in FIG. 3 drives the coupling 65, and the other worm is also driven by the coupling spindle 63.

As described above, according to this embodiment, in the conventional up-coiler winding method, in the case of a coil having an inner diameter of 600 to 700 mm, due to the stability of the coil support, the coil can only be wound up to about 1500 mm, resulting in poor productivity. That is, with a coil of this size, a coil weight of only about 5 to 10 tons could be secured, which was unsatisfactory for modern production equipment.

However, in this example, it is possible to stably wind a large coil of 1500 mm or more, and it is also possible to wind a coil of any diameter up to the actually required 10 to 40 tons. Summer.

〔Effect of the invention〕

As described above, according to the present invention, the position of the support roller located on the rear end side in the direction in which the plate material enters is made variable, and the support roller is supported as the coil diameter increases as the coil winding progresses. By supporting the point using a support mechanism that moves the position of the point in the direction of increasing diameter of the coil, a coil having a sufficiently large diameter can be wound stably.
