Description

[Detailed description of the invention] [Industrial application field] The present invention is applicable to long I-shaped steel whose rolled cross section is I-shaped, long H-shaped steel whose rolled cross-section is H-shaped, etc. The present invention relates to a winding device capable of continuously winding up a long material having an irregular cross section.

[Conventional technology]

Long materials with irregular cross sections, such as I-type steel and H-type steel, are generally formed by continuous rolling with rolling rollers. When storing long materials with irregular cross-sections such as I-type steel and H-type steel, cut the long materials with irregular cross-sections one by one to a certain length using a cutter, and store the cut pieces in a warehouse, etc. was.

[Problem that the invention attempts to solve]

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a winding device for long materials with irregular cross sections, which can wind up long materials with irregular cross sections, such as I-type steel and H-type steel. .

[Means for solving problems]

A winding device for a long material with an irregular cross section according to the present invention includes a base, and an outer peripheral part provided on the base and having a shape that approximately corresponds to the shape of a part of the outer peripheral surface of the long material with an irregular cross section. a curling roller device which has a curling roller formed of a material and which continuously curves a long material having an irregular cross section in a spiral shape; and a winding drum device having an outer peripheral surface around which a long material having an irregular cross section is wound.

The base serves as a fixed part of the winding device for a long material with an irregular cross section according to the present invention, and is installed on a concrete floor or the like. Generally, a conveying device is installed on the base to convey a long material having an irregular cross section to a curling roller device. The conveyance device can be formed by arranging several pairs of conveyance rollers in parallel.

A curling roller device is used to continuously curve a long material with an irregular cross section in a spiral shape, and is generally composed of two driving guide rollers and one driven curling roller, and is made of I-shaped steel or H-shaped steel. It is possible to press and bend long materials with irregular cross-sections such as . The outer periphery of the guide roller and the outer periphery of the curling roller have a shape that approximately corresponds to the shape of a part of the outer peripheral surface of the long material with an irregular cross section. Therefore, if the long material with an irregular cross section is an I-type steel, The curling roller is formed with an outer peripheral portion having a shape corresponding to the shape of the curling roller. That is, since the cross section of the I-beam steel is formed by two short sides and one long side connecting the middle part of the short sides, the outer periphery of the guide roller and the outer periphery of the curling roller A protrusion is formed that contacts the short side and the long side.

In addition, several types of guide rollers and curling rollers with different shapes of the outer periphery are prepared, and depending on whether the long material with irregular cross section is I type steel or H type steel, etc., depending on the shape of the long material with irregular cross section. The guide roller and curling roller can also be replaced.

It is desirable that the curling roller device has a curvature adjustment mechanism that changes the curvature of the elongated material having an irregular cross section. The curvature adjustment mechanism can be formed, for example, by an adjustment member that adjusts the position of the curling roller (the central free roller shown in FIG. 1).

The winding drum device is a device that has the function of winding up a long material with an irregular cross section that is bent by a curling device. The take-up drum device has a take-up drum main body that is disk-shaped and rotatably supported on a base directly or via a speed reduction mechanism, a speed increase mechanism, etc., on the rotating shaft of a drive motor. As in the embodiments described below, a guide member such as a support roller can be provided on the outer circumference of the winding drum body.

Preferably, the base has a control device that controls the take-up drum device and the curling roller device so that the rotation speed of the take-up drum device corresponds to the rotation speed of the curling roller device.
The control device may be formed by a device controlled by a microcomputer or may be formed by a device controlled by a sequence. That is, by using a torque motor and controlling its torque using a microcomputer, both rotational speeds can be matched.

The control device can also be formed using a pulse generator and a CPU, for example. A pulse generator is installed on the rotating shaft of the curling roller, and the pulse generator generates pulses proportional to the rotational speed of the curling roller.Then, the pulses are input to the CPU via the input interface, and the pulses are input to the CPU through the input interface to change the rotational speed of the curling roller. The CPU outputs a control signal corresponding to the amount of curling to the drive circuit that rotationally drives the winding drum device, and the rotation speed of the winding drum device and the rotation speed of the curling roller of the curling roller device are can be controlled accordingly.

If a control device with such a pulse generator is installed, even if the rotational speed of the curling roller decreases and the amount of fed out long material with an irregular cross section decreases, the rotational speed of the winding drum device will also increase in synchronization with this. Since it is smaller, it is possible to prevent excessive force from being applied to the elongated material having an irregular cross section.

[Effect]

A typical method of using the winding device according to the present invention will be explained. That is, with the winding device according to the present invention placed adjacent to a rolling device or the like, a long material having an irregular cross section such as an I-shaped steel rolled by the rolling device is guided to a curling roller. Then, the long material having an irregular cross section is bent to a constant curvature using curling rollers. By engaging the tip of the long material with an irregular cross section that has been curved in this manner with the winding drum device, the long material with an irregular cross section that has been curved by the curling roller can be wound one after another onto the winding drum device. It will be done.

[Effect of idea]

As explained above, according to the winding device for a long material with an irregular cross section according to the present invention, a long material with an irregular cross section such as I-shaped steel or H-shaped steel formed by rolling etc. can be continuously bent in a spiral shape. It can be rolled up.
