The present invention relates to a scrim metal material dimension measuring machine capable of measuring the length, height, and width of a remaining metal after machining a metal plate or a plate material, and managing the dimension, thereby preventing waste of material.

Generally, metal sheets and sheets are manufactured to a certain size, and when they are cut and sold to meet the customer's demand, various sizes of scrap metal are left which are difficult to manage. Even though these metal materials can be used enough, it is difficult to manage them, and most of them are treated as scrap metal and sold on solid objects.

Of course, when the size of these scrap metal materials is more than a certain level, the dimensions may be measured and reused by various methods. A basic method for measuring the dimensions of such scrim metal materials is a method of manually measuring dimensions using a measuring device such as a tape measure. Recently, a three-dimensional image of a scrim metal material is measured, 3D measurement methods are often used to calculate the dimensions of a material.

However, it is advantageous to accurately measure the dimensions of the metal material in the case of the 3D measurement method. However, in the case of the 3D measurement method, it is advantageous to measure the dimensions of the metal material by hand, It is difficult to meet the demand of the field because the measurement speed is not fast as well as the cost is high.

On the other hand, various methods for measuring the dimension of the workpiece are presented, and a dimension measurement apparatus of various structures using the dimension measurement method of the workpiece is disclosed. For example, Patent Document 1 discloses a device for measuring a workpiece using a non-contact type sensor, Patent Document 2 discloses a device for measuring the dimensions of a rotating workpiece, and Patent Document 3 discloses a device for measuring the dimensions of a sloped workpiece &Quot;

However, the above-mentioned dimensional measurement devices are only devices for measuring the dimensions of various kinds of workpieces that are being prepared or processed, and they are applicable to a device for measuring the dimensions of the remaining metal material after machining the metal material to the machining dimensions However, most of them are made of expensive parts, resulting in a high production cost.

As shown in the drawing, the present invention includes a main frame 10 having two LM guides 11 spaced apart at regular intervals; A transfer plate (12) on which the measurement object (50) is placed and horizontally moved along the LM guide (11); An initial position sensing unit 13 provided at one side of the main frame 10 and having an alignment sensor 13 'for sensing an initial position of the measurement object 50 placed on the transfer plate 12; A horizontal conveying unit 14 installed on the main frame 10 to horizontally move the conveying plate 12; A width measuring unit 15 having a width detecting sensor 15 'installed to be movable along the width direction of the main frame 10 at a position spaced apart from the alignment sensor 13'; And a height detection sensor 17 'that moves up and down along the LM guide 16' of the vertical frame 16 installed perpendicular to the main frame 10 at a position corresponding to the width detection sensor 15 ' A height measuring unit 17; The horizontal conveying unit 14, the width measuring unit 15 and the height measuring unit 17 are respectively controlled according to signals of the alignment sensor 13 ', the width detecting sensor 15' and the height detecting sensor 17 ' And a controller 20 for calculating a length, a width, and a length of the measurement object 50, respectively.

Here, the transfer plate 12 has an aligning step 12 'protruding at a predetermined height so as to facilitate the alignment of the measurement object 50, and the initial position sensing unit 13 includes the alignment sensor 13' .

The horizontal conveying unit 14 includes a first motor 14a installed at one longitudinal end of the main frame 10 and a second motor 14b coupled to a bottom of the conveying plate 12 by a ball- And a main screw 14b for horizontally moving the conveying plate 12 while rotating in the forward or reverse direction by the conveying roller 14a.

The width measuring unit 15 is rotated by a horizontal support plate 15a installed on the main frame 10 and a second motor 15c installed on one side of the horizontal support plate 15a, And a fixed bar 15d provided with the width detecting sensor 15 'and a moving block 15e which is fixed to the screw 15b by a ball screw and moves back and forth, And a guide block 15f installed at one side of the horizontal support plate 15a so as to penetrate the fixing bar 15d and guide the fixing bar 15d to linearly move.

The height measuring unit 17 may be any structure as long as it can move the height detecting sensor 17 'up and down, but it is preferable to move the height detecting sensor up and down using the third motor 17' ' .

The control unit 20 controls the length and width of the measurement object 50 using a function of the movement speed and the movement time of the conveyance plate 12, the width detection sensor 15 'and the height detection sensor 17' And height, respectively.

The control unit 20 may further include a label printer 25 for automatically printing a label and a storage position and a control number together with the length, width, and height information of the measurement object 50 calculated by the controller 20 . In this case, information on each measurement object can be confirmed using the label attached to the measurement object 50, and the information can be loaded at a predetermined position. In addition, it becomes very easy to manage the measurement objects 50 by dimension by making the storage position, management number, and size information recorded on the label each a database.

The metal scantlings of the metal scantlings can accurately measure the scantlings of the metal scantlings after finishing the metal scantling or the metal scantlings and manage the scantlings of the metal scantlings according to the dimensions, Thereby preventing waste.

The measurement object 50 is positioned on the transfer plate 12 so that the measurement object 50 is detected by the alignment sensor 13 'of the initial position sensing unit 13. [ At this time, the measurement object 50 is seated in contact with the alignment jaw 12 'of the transfer plate 12, thereby preventing the measurement object 50 from moving and enhancing the accuracy of dimension measurement.

When the alignment sensor 13 'senses the measurement object 50 and transmits a signal to the control unit 20, the control unit 20 sends an operation signal to the first motor 14a of the horizontal transfer unit 14 . The conveying plate 12 starts to move horizontally according to the operation of the first motor 14a.

Thereafter, when the measurement object 50 is sensed by the height sensor 17 'of the height measuring unit 17, the control unit 20 stops the first motor 14a and the third motor 17' And stops the third motor 17 'when the height detection sensor 17' does not detect the measurement object 50 by moving the height detection sensor 17 'upward. The controller 20 calculates the height h of the measurement object 50 using the moving speed and the moving time of the height sensor 17 ' To return the height detection sensor 17 'to its initial position.

When the height detection sensor 17 'is returned to the initial position, the control unit 20 operates the second motor 15c of the width measuring unit 15, and when the second motor 15c is operated, The fixed bar 15d provided with the detection sensor 15 'moves along the width direction of the main frame 10. [ Then, the sensor 15 'is repeatedly measured when the transfer plate is conveyed after the sensor reaction. At this time, while measuring the minimum width value, the height detection sensor 17 'repeats up and down movement to calculate the measured minimum height value. The controller 20 calculates the width w of the measurement object 50 using the movement speed and the movement time of the width detection sensor 15 '. Then, the control unit 20 drives the second motor 15c in the reverse direction to return the width detection sensor 15 'to the initial position.

When the width detection sensor 15 'returns to the initial position, the control unit 20 operates the first motor 14a again to horizontally move the transfer plate 12. Thereafter, if the measurement object 50 is not detected by the height detection sensor 17 ', the control unit 20 stops the first motor 14a, and the control unit 20 determines the moving speed and the movement time of the transfer plate 12 The length 1 of the measurement object 50 is calculated. It goes without saying that after the calculation of the length of the measurement object 50 is completed, the first motor 14a is driven in the reverse direction to return the transfer plate 12 to the initial position.

When both the length l, the width w and the height h of the measurement object 50 are calculated through the above process, a storage position and a management number matching the dimensional information of the measurement object 50 are given, A label is attached to the measurement object 50 by outputting the label on which the information is recorded by using the label output device 25. [

Then, the measurement object 50 is loaded and stored in a predetermined storage position, and the control number, the storage position, and the dimension information recorded in the label are arranged in a database so that the required size of the metal strip can be retrieved and used.

Although the horizontal transfer part and the width measurement part are used to calculate the length and width of the measurement object as a function of the movement speed and the movement time, the length and width of the measurement object may be calculated from the image of the measurement object captured by the camera.

That is, as shown in FIGS. 6 and 7, a main frame 30 having a pedestal 31 on which a measurement object 50 is placed; A height detection sensor 33 that moves up and down along the LM guide 36 of the vertical frame 35 installed perpendicular to the main frame 30; A camera 37 installed at an end of the vertical frame 35 for photographing a measurement object 50 placed on the pedestal 31; A length measuring sensor 33 for controlling the movement of the height sensor 33 in accordance with a signal from the height sensor 33 and for measuring the length of the object 50 using the image taken by the camera 37, And a control unit 40 for calculating the height of the object to be measured 50 by calculating the width of the measurement object 18 and the height of the object 50 by using the signal of the height detection sensor 33.

In this case as well, it is possible to install the label output device 45 that automatically prints the storage position and the control number, together with the length, width, and height information of the measurement object 50 calculated by the control unit 40, Do.
