Description

Shape Steel Discharging Apparatus and Discharging Method {Shape Steel Discharging Apparatus and Discharging Method}

The present application relates to a beam discharge device and a discharge method, and more particularly to a beam discharge device and discharge method for efficiently loading the section steel cut to the length required to prepare the beam for use in offshore structures, such as ships.

In general, the shaped steel used in the production of offshore structures, such as ships, and auxiliary facilities of offshore structures, has various shapes and lengths. These sections should also be cut to the length required to carry the shaped steel from steel mills to form offshore structures.

Conventionally, the process of cutting various types of steel beams has been made manually, and the worker directly performs the process of aligning the cutting steels or cutting them with gas in the cutting process.

Recently, in order to improve the efficiency of the cutting operation, a cutting steel cutting system for automatically cutting the cutting steel by a robot has been developed. Typically, the section steel cutting system is required to load the sections in the order in which they are cut because the sections are sequentially cut into the sections required to form part of the offshore structure. In addition, the section steel may be divided into a star board member constituting the right side of the marine structure and a port member constituting the left side based on the bow direction of the marine structure.

Then, in order to reduce the member selection time in the fabrication of the offshore structure, the cut steel is required to be loaded separately from the starboard member and the port member.

Conventional section steel discharge systems consist of conveyors, pushers, loading stacks and sensors. One side of the section steel cut by the section cutting system is marked with a mark that distinguishes the starboard member from the port member before and after cutting. The cut section steel is transferred through the conveyor, and a port sensor is installed at a distance from the starboard sensor and the starboard sensor installed at one side of the conveyor.

If the section steel being transported is a starboard member, the conveyor is stopped by detecting the starboard sensor. Then, the pusher provided on one side of the conveyor discharges the section steel toward the storage base plate located on the other side of the conveyor. The loading table is divided into a region where the starboard member is loaded and a region where the port member is loaded. In addition, the loading table has a free space in consideration of the maximum length of the steel.

However, in the conventional section steel discharge system, since the discharge position of the cut section steel is determined by the installation position of the sensor, the phenomenon that the members are concentrated in a specific position occurs. In addition, the free space of the wide pile plate eventually becomes unused space, which is spatially inefficient, and there is a problem in that work efficiency decreases because the section steel loaded on the pile plate is moved to another place through a crane.

Loading unit 600 is located on one side of the transfer unit 200, the shape steel (M) may be loaded. As shown, the loading part 600 is disposed along the longitudinal direction of the transfer part 200. The loading unit 600 may have a loading area that is divided according to the type of the section steel. The loading area may be the port member area 610 and the starboard member area 620. In addition, the port member region 610 or the starboard member region 620 has a constant width and forms a loading line corresponding to the total length of the port member region 610 or the starboard member region 620. In addition, the loading unit 600 may include a body portion 630 and a guide portion 640 facing substantially perpendicular to the longitudinal direction of the body portion 630.

The material of the body portion 630 may be the same as the material of the shape steel (M) to prevent rust of the shape steel (M) as well as the body portion 630 itself.

The guide part 640 prevents damage of the shaped steel M due to surface contact with the upper portion of the body portion 630 when the shaped steel M is loaded from one side of the body portion 630. It may be installed to facilitate the movement of M). In addition, the guide part 640 may have the same height as the roller with respect to the bottom of the place where the section steel discharge device is installed. In addition, the guide part 640 may be disposed in the body part 630 to correspond to the arrangement of the plurality of rollers. In addition, the guide part 640 may be the same as the outer diameter of the roller. Accordingly, when the shape steel M is moved from the transfer part 200 to the loading part 600 by the pusher 300 to be described later, the shape steel M may be prevented from being shaken and discharged to a desired position. In addition, the material of the guide part 640 may also be the same as the material of the shape steel (M) to prevent rust of the body portion 630, the guide portion and the shape steel (M).

The pusher 300 is located at the other side of the transfer part 200, and may discharge the shaped steel M transferred by the transfer part 200 to the loading part 600. The pusher 300 may include a contact portion in which the shape steel M is in surface contact, and a cylinder capable of reciprocating the contact portion in the direction of the loading portion 600 from the transfer portion 200. The cylinder may be a hydraulic cylinder using a fluid or an electric cylinder using an electric, but the device is not limited to the cylinder and a device provided with a driving force capable of reciprocating a contact may be applied.

The contact portion of the pusher 300 may be moved to one end of the loading portion. In addition, the contact portion of the pusher 300 may have a shape corresponding to the upper portion of the roller and the upper portion of the guide portion 640. Accordingly, the contact portion moves along the upper portion of the roller and the upper portion of the guide portion, thereby preventing the contact portion from shaking.

As shown in FIG. 3, the pushers 300 may be formed in pairs at positions corresponding to the starboard member region 610 and the port member region 620. The total length of the contacts of each pair of pushers 300 may be similar to the length of port member region 610 or starboard member region 620. On the other hand, unlike shown, the pusher 300 is not made of a pair, it may be made of one corresponding to the length of the port member region 610 or the starboard member region 620.

The sensor unit 400 is located at the other side of the transfer unit 200, and may sense the type of the steel or the presence of the steel. The sensor unit 400 may be formed of a plurality of sensors corresponding to the type of section steel. In addition, the sensor unit 400 may determine the length of the shaped steel M by sensing the presence or absence of the shaped steel M, and calculating the total lengths of the plurality of sensors sensing the shaped steel M. As shown, the sensor unit 400 includes a port member sensor 410 for sensing the port member P and a starboard member sensor 420 for sensing the starboard member S.

The port member sensor 410 may be disposed at a position corresponding to the port member region 610 based on the transfer part 200. In addition, the port member sensor 410 may be disposed at a predetermined interval between the plurality of rollers of the transfer unit 200. The port member sensor 410 may determine whether the shaped steel M is the port member P by sensing a mark attached to one side of the shaped steel M.

Similarly, the starboard member sensor 420 may be disposed at a position corresponding to the starboard member region 620 with respect to the transfer part 200. In addition, the star board member sensor 420 may be disposed at a predetermined interval between the plurality of rollers of the transfer unit 200. The starboard member sensor 420 may determine whether the shaped steel M is the starboard member S by sensing a mark attached to one side of the shaped steel M.

The control unit 500 may control the pusher 300 to compare the length of the section steel M sensed by the sensor unit 400 with the loading line of the loading section so that the section steel can be loaded to the loading line as much as possible. A detailed description of the control unit 500 will be described later with reference to the drawings.

Accordingly, the shaped steel discharge device 100 according to an embodiment of the present invention compares the length of the shaped steel sensed by the sensor unit 300 with the loading line of the loading part 600 so that the shaped steel can be loaded on the loading line as much as possible. By making it possible, the space of the mounting part 600 can be utilized efficiently compared with the prior art.

Referring to FIG. 2, the control unit 500 may exchange signals with the sensor 400, the transfer unit 200, the pusher 300, and the storage unit 600. When the section steel is cut by the section steel cutting system and seated on the section 200, the controller 500 operates the section 200 to convey the section steel. In addition, the controller 500 receives a signal in which the type and presence of the steel beams are sensed by the sensor 400. Next, the control unit 500 compares the length of the section steel and the loading line of the loading unit. The controller 500 determines a loading line for loading the shaped steel on the loading line as much as possible, and then transfers a signal to the transfer part 200 when the sheet steel is transferred to a position corresponding to the determined loading line to operate the transfer part 200. Stop it. In addition, the control unit 500 may operate the pusher 300 to discharge the section steel from the transfer unit 200 to the loading unit 600.

On the other hand, the section steel discharge device 100 according to an embodiment of the present invention may further include a storage unit 700 for storing the placement information of the stacked section of the stacking portion calculated by the control unit 500. A detailed description of the storage unit 700 will be described later with reference to the accompanying drawings.

As such, the space of the loading unit 600 may be efficiently utilized through the control unit 500 applied to the shape steel discharge device according to the exemplary embodiment of the present invention.

Figure 3 is a flow chart showing a method for discharging the section steel according to an embodiment of the present invention. Referring to FIG. 3, a method of discharging a section steel according to an embodiment of the present invention includes a transfer step of transferring the cut section steel by a transfer unit, a sensing step of sensing a section steel transferred through a plurality of sensors, and a sensing step of sensing the section steel. Determining step of determining the length of the section steel, comparing the length of the sensing section and the loading line of the loading section and the determining step of determining the loading line so that the section steel is loaded to the loading line as maximum and the discharge step of discharging the section steel to the determined loading line can do.

First, the section steel is cut to the desired length by the section steel cutting system. In the transfer step, the cut section steel is seated on the transfer unit and transferred. The sensing step senses the type and presence of the section steel through the sensor unit installed spaced apart at regular intervals along the longitudinal direction. The determining step may include a calculating step of calculating the length of the steel beam through the distances of the plurality of sensors in order to determine the sensed length of the steel beam. That is, the control unit can know the length of the steel beam by receiving the signal of the sensor unit and calculating the distance of the sensor simultaneously sensed among the plurality of sensors. On the other hand, the determination step may include a calculation step of calculating the sensing time of the section steel and the feed rate of the section steel sensed through the sensing step to calculate the length of the section steel. That is, if a sensor is installed at a position corresponding to the starting point of the starboard member region and the port member region of the section steel conveyed by the conveying section, the sensor calculates the time for sensing the section steel and the moving speed of the conveying section. The length of the section steel can be known.

Accordingly, the section steel discharge device according to the calculation step is one sensor in the position corresponding to the starting point of the star board member region and the port member region of the section steel conveyed by the transfer unit without installing a plurality of sensors shown in FIG. There is an advantage to install it.

In the determining step, the loading position of the loading line is determined by comparing the length of the section steel with the loading line of the loading section through the controller to determine the loading position of the loading line so that the section steel is loaded to the loading line as much as possible, thereby determining the discharge position of the section steel transferred by the transfer section. Detailed description of the determination step will be described later with reference to the accompanying drawings.

The discharging step may include a stopping step of stopping the operation of the transfer unit through the control unit. In addition, in the discharge step, the control unit operates the pusher to discharge the section steel to the determined loading line.

As described above, in the method for discharging the section steel according to an embodiment of the present invention, the section steel is loaded to the loading unit as much as possible, and then the section steel loaded in the loading unit can be collectively moved through a crane, thereby cutting not only the entire section steel discharge device but also the section steel. The working efficiency of the system itself can be increased.

It is a figure which shows a mode that a shape steel loads on a loading part. As described above, the loading unit 600 may have a port member region 610 and a starboard member region 620. The port member region 610 or the starboard member region 620 may be divided into a unit region having a predetermined length and width.

Six loading lines are shown in each of the port member region 610 and the starboard member region 620, but the present invention is not limited thereto and may vary depending on the size of the loading unit 600. In addition, the illustrated loading line shows a case where the width of the section steel is constant. As described above, the loading line may not coincide with the unit area according to the width and length of the various section steels. Afterwards, a method of determining a position in which the port member is loaded in the loading part will be described.

If the section steel does not exist in the first loading line (L1) or the length of the first loading line (L1) is greater than the length of the section steel to be loaded, minus the length of the section steel loaded in the first loading line (L1), The steel is loaded on the first loading line L1 so that one side marked with the mark coincides with one end of the loading line L1 adjacent to the steel cutting system 11. If the length of the first loading line L1 minus the length of the section steel loaded on the first loading line L1 is smaller than the length of the section steel to be loaded, the section steel is loaded on one side of the second loading line L2.

Next, when the section steel to be loaded is smaller than the empty space of the first loading line L1 and the second loading line L2, the section steel is loaded on the first loading line L1. On the other hand, when the shaped steel is larger than the empty space of the first loading line L1 and smaller than the empty space of the second loading line L2, the shaped steel is loaded in the second loading line L2. By comparing the length of the beam being transported in this manner with the loading line, the steel can be loaded on the loading line as much as possible, thereby increasing the space efficiency of the loading part.

Referring to Figure 5 will be described how the form steel stored in the storage portion stored in the loading portion. 5 (a) is a diagram illustrating an example in which the loading unit and the transfer unit are arranged in opposite directions, unlike in the exemplary embodiment of the present invention.

As described above, the loading area may be divided into a unit area having a predetermined length and width. Each unit area may be set to a virtual address.

As shown in (b) of FIG. 5, the virtual addresses may be represented by a matrix. The number 0 in the matrix indicates that there is no section steel in the unit region, the number 1 indicates that the section steel exists, and the number 2 indicates that there is a section steel in which the marked mark is present in the section steel. The controller determines the loading position of the above-described shaped steel and stores the loading position in a storage unit in a matrix. That is, the storage unit may store the numbers 0, 1, and 2 in the unit area of the loading unit to determine the loading state of the loading unit. In addition, the control unit may then be used to determine the discharge position of the steel using a matrix stored in the storage before determining the loading position of the steel. In addition, by using the loading position information stored in the storage unit, the crane can be automatically operated without the operator manually.

It will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention as defined by the appended claims, It is obvious.
