Description

CONTINUOUS FEEDER STEEL SHEET OF STEEL MANUFACTURING APPARATUS FOR BUILDING

Technical Field

[1] The present invention relates to an apparatus for continuously feeding a steel plate material in a shape steel manufacturing apparatus for architecture in which it makes it possible to a tape type steel plate material can be continuously and in series supplied to a roll forming machine of a shape steel manufacturing apparatus which manufactures a shape steel for architecture having a channel shaped cross section by supplying a tape type steel plate material to a roll forming machine.

[2]

Background Art

[3] Generally, a shape steel manufacturing apparatus is able to manufacture a shape steel having a channel shaped cross section with the help of a forming roller through multip Ie processes by supplying a tape type steel plate material having a certain length to a roll forming machine. Since a conventional manufacturing apparatus is designed to manufacture a shape steel having a certain length while supplying a prepared steel plate material having a certain length, once the prepared steel plate material is all consumed, a forming work should be stopped until a new material is prepared and supplied, which leads to a non-efficient work. So as to overcome the above problem, a tape shaped steel plate material is rolled in a roll shape for manufacturing a coil steel plate. Namely, a forming work is performed in a supply apparatus which is able to directly input a steel plate material into a forming machine by unwinding a steel plate material from the coil steel plate as a coil steel plate is disposed in an input unit of a roll forming machine.

[4] However, once the coil shape steel plate is all consumed, it is needed to supply a new coil shape steel plate. Since it is impossible to continuously supply a steel plate material, once one steel plate is all consumed, a material supply preparation step is needed for brining and supplying another steel plate material, which needs lots of workers and time. So, a roll forming machine should be stopped. Namely, a continuous forming work cannot be performed, which leads to a low productivity.

[5]

Disclosure of Invention Technical Problem

[6] Accordingly, it is an object of the present invention to provide an apparatus for continuously feeding a steel plate material in a shape steel manufacturing apparatus for ar-

chitecture in which a steel plate material storing unit is provided for continuously supplying a steel plate material, and a steel plate material stored in a storing unit is continuously unwound and supplied to an input unit of a roll forming machine.

[7]

Technical Solution

[8] To achieve the above objects, a steel plate material is continuously supplied into an input unit of a roll forming machine E through a supply apparatus which comprises a steel plate material apparatus unit A which engages a coil steel plate to a steel plate material apparatus unit, with the coil steel plate being commercially sold in a coil shape, and unwinds the stored steel plate material; a steel plate material transfer connection unit B which transfers a steel plate material unwound from a coil shape steel plate and is formed of a welding machine and a polishing machine for connecting a steel plate material on a transfer path, and a steel plate material storing supply unit D for storing by winding a certain amount of the steel plate material on a winding drum, and unwinding the stored steel plate material from its inner side and supplying to a roll forming machine.

[9]

Advantageous Effects

[10] In the present invention, as a supply apparatus is used in combination with a known automation apparatus, so a coil steel plate is loaded in an apparatus unit A and is unwound from the same, and the coil spring plate is stored in a steel plate material storing supply unit through a transfer connection unit B, and a forming work is performed while unwinding the stored steel plate at a certain speed needed for the forming work, so a continuous forming work can be performed without stopping the supply of a material, which leads to a continuous forming work. The shape steel so manufactured is cut with a certain length, and is heated by an electric heater G, and a surface of the same is painted by a painting unit H, and is dried while being transferred, and is transferred to a size surface by means of a water mill-shaped rotation transfer unit I, and is collected in a product packing unit L through a conveyor transfer unit J and a rotation transfer unit K, and is packed by a certain amount. The above whole processes might be performed in an automated system for thereby significantly enhancing productivity.

[46] Since an electric circuit used in the present invention is known art, its detailed description will be omitted.

[47] In the present invention, an upper body of the steel plate material apparatus unit A is overlapped on an upper plate of the fixing unit and is engaged with a spherical bearing, and a rotation gear formed in a rotary shaft of the upper body is engaged with a driving gear of the hydraulic motor, so it rotates 180 degrees in a clockwise or counterclockwise direction as the hydraulic motor is driven. A flexible support shaft 160 is formed in both sides of the upper body, and when a coil steel plate is engaged to a flexible support shaft, the upper body is rotated, and the flexible support shaft is

rotated while facing outward, and the coil steel plate is inserted into the flexible support shaft from the outer side. So, the coil steel plate can be easily engaged, and a flexible support shaft is expanded after the coil steel plate is engaged. A support shaft is tightly supported in the center unit of the coil steel plate for thereby reliably supporting the same. A flexible support shaft is formed in both sides of the upper body, and two coil steel plates can be engaged in the upper body. The work for engaging the coil steel plate is easy. When the coil steel plate is engaged in the steel plate apparatus unit, the upper body is returned to its original position, and the outer end of the coil steel plate is released, and is inputted into the steel plate material transfer connection unit.

[48] In addition, a steel plate material transfer roller 200 is disposed in both sides of a transfer path of the steel plate material transfer connection unit, and a side guide 201 is disposed in both sides of a transfer path along which a steel plate material is transferred, so a tape steel plate passing along a transfer unit is stably transferred while being not escaped. An electric welding machine B4 and an electric polishing machine B 5 are disposed on the transfer path, so the tape steel plates are connected with other, and the connection unit is welded, so a reliable transfer work is obtained. The steel plate material storing supply unit is constituted as a winding drum Dl is disposed in a fixing frame and rotates left and right by means of a left and right rotation motor or is temporarily stopped. A winding unit is formed on an outer surface of the winding drum for overlapping steel plate materials, and a steel plate material formed of three or four coil steel plates can be wound and stored. The steel plate material wound on an outer surface of the winding drum is released through a first roller conveyor D2 disposed in a center of the winding drum and a spiral roller conveyor D3 to the outside from the inner end through the discharge unit DlOO formed in an inner surface of the winding unit, so a steel plate material might be released from the inner center to the outside while winding a steel plate material on a winding unit of the winding drum. Therefore, a continuous supply work can be performed as a steel plate material can be continuously supplied while the steel plate material being consumed.

[49] When storing the steel plate material in the winding drum of the present invention, a winding drum is rotated in a clockwise direction, and an outer end of the steel plate material wound on the outer surface is slightly unwound, and is moved to a welding position of the transfer connection unit B, and an outer end of the steel plate material disposed in the coil steel plate apparatus unit A is unwound and moved to a welding position of the steel plate material transfer connection unit B, and both ends are welded using an electric welding machine, and the welded portions are polished by using a polishing machine, and the winding drum is rotated in a counterclockwise direction, and the coil steel plate disposed in the coil steel plate apparatus unit is moved to an

outer surface of the winding drum and is wound thereon. When using the steel plate material wound on an outer surface of the winding drum, the operation of an outer transfer roller of the steel plate material connection unit is stopped, and the steel plate material is discharged through a roller conveyor formed in an inner side of the winding drum, and is supplied to a roll forming unit for thereby performing a forming work. At this time, a winding drum is slowly rotated in a clockwise direction depending on a discharging speed, so the steel plate material can be efficiently discharged. During the above operation, as the winding drum rotates in a clockwise direction, even when a tensional force of the steel plate material wound on its outer surface is loosened, the steel plate wound on a winding unit is not escaped from a guide groove by means of a vertical roller formed in a roller surface, and since it is rotated depending on the speed that it is supplied to the roll forming unit, it is possible to safely discharge, and a new steel plate material can be connected and stored before the steel plate material wound on the winding drum is all consumed, and the newly stored steel plate material can be continuously. As the above operation is continuously repeated, a steel plate material can be continuously supplied to the roll forming machine for thereby implementing a non-stop forming work along with an efficient shape steel forming work.

[50] In particular, a roller surface is formed in a winding portion of the winding drum Dl of the present invention, and a roller groove is formed as well. As a steel plate material wound on the winding unit is closely contacted with a drum surface, and is unwound while being released from the same, a smooth transfer of the steel plate material is obtained, and a steel plate material might be wound or unwound from the winding drum by means of a center portion of the winding drum Dl, the first roller conveyor D2 formed in an outer side of the center, and the spiral roller conveyor D3. So, it is possible to wind a material on a winding drum surface or to unwind from the same, so the objects of the present invention can be obtained without any problems. The guide groove might have a certain area corresponding to the width of the steel plate material by widening or narrowing the distance of the transfer unit by rotating the left and right screw rod. So, even when a dimension of the steel plate material is changed, it can be adjusted. The height or interval of the flat plate B34 of the apparatus unit can be adjusted. An enough work space can be obtained when performing a welding work or a polishing work, so a convenient work can be advantageously obtained.
