In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 1 is a configuration diagram showing a state where a work shape measuring apparatus according to an embodiment of the present invention is installed on a conveying roller unit, FIG. 2 is a view showing a work shape measuring apparatus according to an embodiment of the present invention And FIG. 3 is a configuration diagram showing a cleaning apparatus in the work shape measuring apparatus according to an embodiment of the present invention.

1 to 3, a workpiece shape measuring apparatus 100 according to an embodiment of the present invention includes a housing 110, a guide rail 120, a shape measuring unit 130, and a cleaning device 140 .

 A through hole 111 is formed in the housing 110 to allow the material 20 to pass therethrough. The housing 110 is disposed between the conveying roller portions 10. The housing 110 is generally formed in a cylindrical shape. The material 20 may be a special steel formed in a predetermined shape.

The guide rail portion 120 is disposed along the circumferential direction of the housing 110. At this time, the guide rail 120 is formed in a ring shape.

The shape measuring unit 130 is installed in the housing 110 so as to surround the work 20 and measures the shape of the work 20 by irradiating the work 20 with light. Light is a laser with straightness.

The cleaning device 140 is movably installed in the housing 110 to remove foreign matter adhering to the shape measuring unit 130. When the work 20 is not transported, the cleaning apparatus 140 removes foreign matter adhering to the shape measuring unit 130 while being operated by the operator or periodically moved. The cleaning device 140 removes foreign substances adhering to the shape measuring unit 130, thereby preventing foreign matter from obstructing the progress of the light. Therefore, the shape of the work 20 can be accurately measured.

The shape measuring unit 130 includes a plurality of light irradiation units 131 disposed along the guide rail 120 in the housing 110 and a plurality of light irradiation units 131 disposed along the guide rail 120 to correspond one- And includes a plurality of light receiving portions 133. The light irradiating unit 131 and the light receiving unit 133 are disposed on the opposite sides so as to correspond one to one. The light irradiating unit 131 irradiates the laser 20 with a laser beam having a directivity and a part of light not blocked by the material 20 reaches the light receiving unit 133. The light irradiated from one light irradiating unit 131 reaches the opposite light receiving unit 133 because the light has a linearity. The control unit 150 calculates the shape of the material 20 by calculating the shape of the light reaching the plurality of light reception units 133.

The plurality of light irradiating portions 131 are disposed on one circumferential side of the housing 110 (one semicircular portion in the circumferential direction) and the plurality of light receiving portions 133 are disposed on the circumferential direction of the housing 110 (The other semicircular portion in the circumferential direction). The plurality of light receiving portions 133 are disposed on the opposite sides of the plurality of light irradiating portions 131 so that the light not blocked by the material 20 reaches the corresponding light receiving portion 133. Therefore, since the light irradiation unit 131 scans light in various directions of the work 20, the shape of the work 20 can be projected to the light reception unit 133 in various directions. That is, since the plurality of light irradiation units 131 and the plurality of light reception units 133 facing each other measure the shape of the work 20 at a plurality of angles, the shape of the work 20 can be measured in various directions .

A ring-shaped guide groove 113 is formed in the housing 110 along the guide rail 120 and a light irradiating unit 131 and a light receiving unit 133 are disposed in the guide groove 113. The light irradiating unit 131 and the light receiving unit 133 are disposed in the guide groove 113 so that foreign substances can be attached to the light irradiating unit 131 and the light receiving unit 133 less.

The cleaning device 140 includes a case 141, a driving wheel 142, a driving motor 143, and a dust collecting part 145. The cleaning apparatus 140 waits between the light irradiation unit 131 and the light reception unit 133 while the light irradiation unit 131 and the light reception unit 133 measure the shape of the work 20. [ Therefore, it is possible to prevent the cleaning device 140 from blocking the path of the light while the light is irradiated by the light irradiating unit 131.

The case 141 is disposed in the guide groove 113. A driving wheel 142 and a dust collecting part 145 are disposed in the case 141. The case 141 is formed to be smaller than the gap between the light irradiation unit 131 and the light reception unit 133 to prevent the light path of the light irradiated by the light irradiation unit 131 from being blocked.

The drive wheel 142 is disposed on one side of the case 141 and rotatably installed on the guide rail 120. The driving wheel 142 is moved along the guide rail portion 120. The drive motor 143 is installed to rotate the drive wheel 142.

The dust collecting section 145 is disposed in the case 141 and collects foreign matter adhering to the guide groove section 113. When the drive wheel 142 is rotated as the drive motor 143 is driven, the dust collecting part 145 moves along the guide rail part 120 to collect foreign matter adhering to the guide groove part 113. The foreign matter is removed while the dust collecting part 145 moves along the guide groove 113 so that the foreign matter adhering to the light irradiating part 131 and the light receiving part 133 is removed. Therefore, it is possible to prevent the light irradiated from the light irradiating unit 131 from being disturbed by foreign matter, so that the shape of the work 20 can be accurately measured.

The dust collecting section 145 includes a brush section 146, a filter section 147, and a suction fan section 148.

The brush portion 146 is disposed inside the guide groove portion 113 to separate foreign matter from the guide groove portion 113. The foreign substance is separated from the light irradiating unit 131 and the light receiving unit 133 by moving the brush unit 146 along the guide groove 113. [

The filter unit 147 collects foreign matter separated from the brush unit 146. The filter unit 147 may be of various forms as long as it collects foreign matter.

The suction fan unit 148 forms a suction force in the filter unit 147 so as to collect foreign matter in the filter unit 147. [ The suction fan portion 148 is provided on the opposite side of the brush portion 146 with respect to the filter portion 147. A suction force is formed in the filter portion 147 by the suction fan portion 148 sucking air so that the foreign matter of the guide groove portion 113 flows into the filter portion 147. [

The operation of the work shape measuring apparatus according to one embodiment of the present invention will be described.

FIG. 4 is a view showing a state in which a light scanning unit and a light receiving unit measure the shape of a work in the work shape measuring apparatus according to an embodiment of the present invention.

Referring to Fig. 4, as the conveying roller portion 10 is rotated, the workpiece 20 is conveyed. Light is irradiated from the light irradiating unit 131 and a part of light not blocked by the material 20 reaches the light receiving unit 133. At this time, since the plurality of light irradiating portions 131 simultaneously irradiate the light having the linearity, the light emitted from the light irradiating portion 131 reaches the plurality of light receiving portions 133. The control unit 150 calculates the shape of the light 20 arriving at the plurality of light reception units 133 to determine the shape of the material 20.

The cleaning device 140 is disposed between the light irradiation part 131 and the light reception part 133 while the light irradiation part 131 and the light reception part 133 measure the shape of the work 20. [ Therefore, it is possible to prevent the cleaning device 140 from blocking the path of the light while the light is irradiated by the light irradiating unit 131.

5 is a view illustrating a state in which a cleaning device is moved along a guide rail portion in a work shape measuring apparatus according to an embodiment of the present invention to clean a light scanning portion and a light receiving portion.

5, a foreign matter adheres to the surface of the housing 110 while the material 20 passes through the through-hole 111 of the housing 110. Referring to FIG. When the operator operates the cleaning device 140 by wireless communication or the like, the drive wheel 142 is rotated by the drive motor 143. As the drive wheel 142 rotates, the cleaning device 140 is moved along the guide groove 113. Also, the controller 150 may be set in advance such that the cleaning device 140 is periodically driven.

At this time, the brush part 146 of the dust collecting part 145 moves along the guide groove part 113 to separate the foreign matter. Further, as the suction fan unit 148 is driven, foreign matter is collected in the filter unit 147. [ Foreign substances adhered to the light irradiation part 131 and the light reception part 133 are also removed as the foreign matter is removed from the guide groove part 113. [ Therefore, since the light irradiated from the light irradiating unit 131 can be prevented from being disturbed by the foreign substance, the shape of the work 20 can be accurately projected on the light receiving unit 133.

As described above, since the cleaning device 140 removes the foreign substances adhering to the shape measuring unit 130, foreign substances can be prevented from obstructing the progress of the light. Therefore, the shape of the work 20 can be accurately measured.

Since the plurality of light receiving portions 133 are disposed on the opposite sides of the plurality of light irradiating portions 131, light not blocked by the material 20 reaches the corresponding light receiving portions 133. [ Therefore, since the light irradiation unit 131 scans light in various directions of the work 20, the shape of the work 20 can be projected to the light reception unit 133 in various directions.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.
