Description

  The present invention relates to a portable color measurement device and a portable color measurement system.

  For various industrial products, the color of the surface is measured by measuring the color of the surface with a colorimeter, etc. at any stage from manufacture to shipment so that the surface color is kept the same between products. Color is managed. The colorimeter includes, for example, a light source that illuminates the surface of an object (also referred to as a colorimetric object) that is a colorimetric object, and a sensor that receives light such as reflected light emitted from the surface. A light receiving unit is provided.

  By the way, the size and shape of the color management target part of the surface of the color measurement object, that is, the color measurement target part (also referred to as color measurement target part) is the shape and size of the color measurement object. It can vary depending on various requirements such as customer requirements and manufacturing methods. However, preparing a different colorimeter for each condition is an economic burden for the manufacturer.

  For this reason, depending on conditions, an exchangeable nose cone is arranged between the color measurement object and the main body of the colorimeter, so that an area to be measured (also referred to as a color measurement target area) can be obtained. A portable color measurement device whose size and the like can be changed has been proposed (for example, Patent Document 1). This nose cone has a window that defines the size of the colorimetric object area, etc., and is mounted on the colorimeter so as to cover the illumination light receiving part, and when the colorimetric object is colorimetrically measured It can function as a member (also referred to as a mask member) that contacts an object.

  In such a configuration, when exchanging the mask member, it may be necessary to change an optical system and a calibration coefficient used for colorimetric calculation according to the type of the mask member. For this reason, in the apparatus of the above-mentioned patent document 1, one or more magnetic switches are provided in the lower half of the main body, and the magnetic field generated from the magnet arranged on the mask member according to the type of the mask member is monitored by the magnetic switch. Then, the type of the mask member is automatically recognized and displayed.

  By the way, for a colorimeter, an integrating sphere is used, so that a method for uniformly illuminating a colorimetric object from any direction (also called a diffuse illumination method) and a reflected light generated on the surface of a colorimetric object Some systems adopt light receiving direction (also called diffuse light receiving system). For this integrating sphere, for example, a white substance such as barium sulfate is often applied to the inner surface in order to diffusely reflect light (diffuse reflection) almost completely. For this reason, the integrating sphere is required to have strength against deformation so that the white substance is not damaged or peeled off by an impact such as dropping. In order to increase the strength of this integrating sphere, the surrounding area near the largest intersecting circle (also referred to as a great circle) that intersects the plane of the integrating sphere (also referred to as the split plane) is reinforced with a holding part such as a metal plate. Then, a configuration in which the integrating sphere is fixed to the casing by fixing the holding portion to the casing is conceivable.

  The illumination light receiving unit 23 includes an integrating sphere 230, a light source unit 231 (see FIG. 12), and a sensor unit 232 (see FIG. 12).

  The integrating sphere 230 is a sphere in which a white paint such as barium sulfate that diffuses and reflects light (diffuse reflection) almost completely is applied on the inner surface. As shown in FIG. 5, the integrating sphere 230 has a main body portion 230BD and a flange portion FL1. The integrating sphere 230 can be formed, for example, by connecting two bowl-shaped portions (also referred to as bowl-shaped portions) 230a and 230b each having a hemispherical inner surface and an outer surface. In the present embodiment, a flange portion FL1 extending outward from the end edge portion is provided at the circular end edge portion of the flange-shaped portion 230b.

In the present embodiment, the mask detection unit 25 detects the type of the mask member 3.

  The reinforcing member 2PL is a member for ensuring the rigidity at the distal end portion 2Tp of the color measuring device 2. Specifically, the reinforcing member 2PL is disposed on the window portion 2WD side of the flange portion FL1, and reinforces the integrating sphere 230. As the reinforcing member 2PL, for example, a plate-like member can be adopted. Further, as the material of the reinforcing member 2PL, for example, a material having high rigidity such as an iron-based material can be employed. Specifically, a sheet metal can be employed for the reinforcing member 2PL. The reinforcing member 2PL is attached to the flange portion FL1 by screws or the like, for example.

  Further, the flange portion FL1 is held by the reinforcing member 2PL so as to surround the great circle portion of the main body portion 230BD of the integrating sphere 230, for example. Thereby, the outer peripheral part of the integrating sphere 230 is protected, and the integrating sphere 230 can be prevented from being damaged. Further, protection and fixing of the mask detection unit 25 held by the flange portion FL1 can also be realized by the reinforcing member 2PL that reinforces the flange portion FL1.

  Further, in the color measuring device 2, a casing 2BD that forms an exterior part is disposed outside the reinforcing member 2PL.

  The mask member 3 is a member that is attached to the distal end portion 2Tp of the color measuring device 2.

  The main body portion 3BD is provided with a window portion 3WD as a second window portion that defines the size of a color measurement target region (also referred to as a color measurement target region) among the color measurement objects. As the window portion 3WD, for example, one having a substantially circular XY section can be adopted. The window 3WD may be, for example, a through hole or a transparent part that transmits light. The window 3WD optically communicates with the window 2WD of the integrating sphere 230 in a state where the mask member 3 is mounted on the tip 2Tp of the color measuring device 2. Here, the mode in which the window portion 3WD and the window portion 2WD communicate optically includes, for example, a mode in which the through hole physically communicates, a mode in which the through hole and the transparent portion face each other, and a transparent portion faces each other. And the like may be included. The mounting portion 3AT is a portion for mounting the mask member 3 to the color measuring device 2. The mask member 3 is also referred to as a target mask, for example.

  The mask member 3 has a configuration that can be attached to and detached from the distal end portion 2Tp of the color measuring device 2. 6 to 8 are views showing a state in which the mask member 3 can be attached to and detached from the colorimetric device 2.

  As shown in FIG. 6, the tip portion 2Tp of the color measuring device 2 is provided with a mounted portion 2AW for mounting the mask member 3 so as to optically communicate the window portion 3WD and the window portion 2WD. It has been. The mounted portion 2AW is a portion for mounting the mask member 3 so as to cover the illumination light receiving portion 23, for example. The attached portion 2AW constitutes a part of the housing portion 2BD, and the mask member 3 is attached to the colorimetric device 2 by attaching the attaching portion 3AT to the attached portion 2AW. .

  In the present embodiment, as a mechanism (also referred to as a mounting mechanism) configured by the mounted portion 2AW and the mounted portion 3AT, the mounting portion 3AT is rotated by rotating the mounting portion 3AT relative to the mounted portion 2AW. A mounting mechanism called a bayonet type or the like that is mounted on the vehicle is employed. In this mechanism, for example, with a plurality of claws provided on the attachment portion 3AT being hooked on a stopper provided on the attachment portion 2AW, the axis Ax1 passing through the centers of the window portions 2WD and 3WD is the center. By rotating the mask member 3, the mounting portion 3AT is fixed to the mounted portion 2AW. The number of claw portions may be three, for example.

  FIG. 7 shows a state where the mounting portion 3AT starts to be mounted on the mounted portion 2AW, and FIG. 8 shows a state where mounting of the mounting portion 3AT on the mounted portion 2AW is completed. In FIG. 7, an enlarged view of the area Ar1 surrounded by a round frame is also shown.

The 3AT is mounted on the mounted portion 2AW of the color measuring device 2. The clockwise direction mentioned here is a clockwise direction when the mask member 3 is viewed in plan in the + Z direction.

  At this time, for example, as shown in FIG. 8, the notch 3Mk is aligned with a circle 2Mk as a mark drawn on the front end 2Tp of the color measuring device 2. At this time, for example, by rotating the mounting portion 3AT clockwise with a certain amount of force, the mounted portion 2AW and the mounting portion 3AT may be fixed to each other in a manner in which they are fitted or locked. . Thereby, the mounting of the mask member 3 to the color measuring device 2 is completed.

  On the other hand, as shown in FIG. 8, the mask member 3 is rotated by a predetermined angle in the counterclockwise direction drawn by the black arrow opposite to that when the mask member 3 is mounted on the color measuring device 2. The mask member 3 is detached from the color measuring device 2. The counterclockwise direction mentioned here is a counterclockwise direction when the mask member 3 is viewed in plan in the + Z direction. At this time, for example, a mode is adopted in which the fitting or locking between the mounted portion 2AW and the mounting portion 3AT is released by rotating the mounting portion 3AT counterclockwise with a certain force or more. May be.

  FIG. 9 is a diagram illustrating a configuration example in the vicinity of the distal end portion 2Tp of the color measuring device 2. In FIG. 9, in order to show the configuration of the flange portion FL1 and the mask detection portion 25, the housing portion 2BD including the mounted portion 2AW and the −Z side portion of the reinforcing member 2PL are shown in a transparent state for convenience. ing.

  As shown in FIG. 9, the mask detection unit 25 includes a plurality of detection units 25 a to 25 d. The flange portion FL1 has portions (also referred to as disposed portions) D1a to D1d where the detecting portions 25a to 25d can be respectively disposed. In the present embodiment, the disposed portions D1a to D1d are portions (also referred to as recesses) in which the outer peripheral portion of the flange portion FL1 is recessed toward the internal space 230S. Here, the concave portion is a notch-like portion provided on the outer peripheral portion of the flange portion FL1.

  When the bowl-shaped portions 230a and 230b constituting the integrating sphere 230 are formed by resin molding, the placement portions D1a to D1d as the concave portions can be formed by molding or processing after molding, for example. .

  And it arrange | positions so that the detection parts 25a-25d may enter in the to-be-arranged part D1a-D1d. Thereby, it is hard to produce the malfunction which the colorimetry apparatus 2 enlarges by arrangement | positioning of the detection parts 25a-25d. Here, the placement parts D1a to D1d have a function of holding the detection parts 25a to 25d. At this time, the flange part FL1 has both a function of fixing the integrating sphere 230 to the housing part 2BD and a function of holding the detection parts 25a to 25d. Thereby, the miniaturization in the color measuring device 2 can be maintained. Further, in the present embodiment, the detectors 25a to 25d are arranged on a substantially concentric circle around the axis Ax1 passing through the center of the window 2WD of the integrating sphere 230 and near the great circle of the integrating sphere 230. ing. The positions where the detectors 25a to 25d are disposed may be slightly deviated from the substantially concentric circle centered on the axis Ax1, but if the position is on a substantially concentric circle centered on the axis Ax1, measurement is possible. Miniaturization of the color device 2 can be easily realized.

  As shown in FIG. 9, in the present embodiment, when the front end portion 2Tp of the color measurement device 2 is seen through in the + Z direction, the plurality of detection units 25a to 25d are not provided with the reinforcing member 2PL. Placed in the part. In the present embodiment, through holes H1a to H1d that penetrate the reinforcing member 2PL are provided. In FIG. 9, the outer edges of the through holes H1a to H1d are indicated by broken lines. In other words, when the mask member 3 is mounted on the mounted portion 2AW, the reinforcing member 2PL has a through-hole in a portion positioned between the space where the mask member 3 is positioned and the detection portions 25a to 25d. H1a to H1d are provided. With such a configuration, it is possible to further improve the impact resistance while maintaining the downsizing of the colorimetric device 2.

  Each detection part 25a-25d can detect to-be-detected part 32a-32d (refer FIG. 12) distribute | arranged to the mask member 3. FIG. Here, in the present embodiment, when the mask member 3 is attached to the attachment portion 2AW, a part of the housing portion 2BD is located in a region between the space where the mask member 3 is located and the detection portions 25a to 25d. Is arranged. In such a case, as the detection units 25a to 25d, for example, a detection unit that can detect the detection units 32a to 32d without being in contact with the detection units 32a to 32d may be employed. Thereby, the exposure to the exterior of the detection parts 25a-25d is reduced by the housing | casing part 2BD. As a result, durability in the color measuring device 2 and robustness in detection of the mask member 3 can be improved.

  Here, in the present embodiment, Hall elements are employed as the detection units 25a to 25d, and magnets as members that generate a magnetic field are employed as the detection units 32a to 32d. According to the Hall element, the magnet can be detected by detecting the magnetic field emitted from the magnet. Thereby, the detection according to the kind of mask member 3 can be implement | achieved easily.

  As shown in FIG. 9, in the present embodiment, when the front end portion 2Tp of the color measurement device 2 is seen through in a plane in the + Z direction, the plurality of detection portions 25a to 25d include the flange portion FL1 and the reinforcing member 2PL. It is arranged in the part which is not arranged. Thereby, detection of the mask member 3 by the mask detection part 25 is hard to be inhibited by the flange part FL1 and the reinforcement member 2PL.

  Here, if the flange portion FL1 is a non-magnetic material, the magnetic field emitted from the magnet can be easily detected by the detection portions 25a to 25d. If the integrating sphere 230 is made of resin, for example, the flange portion FL1 is a non-magnetic material.

  Moreover, if the reinforcing member 2PL is a non-magnetic material, the magnetic field emitted from the magnet can be easily detected by the detection units 25a to 25d. In this case, since the degree of freedom in the arrangement of the reinforcing member 2PL is improved, the impact resistance in the color measuring device 2 can be further improved. As a non-magnetic material and a highly rigid material employed for the reinforcing member 2PL, for example, austenitic stainless steel that is excellent in workability and hardly rusts can be considered. However, some austenitic stainless steels are easily magnetized by various processes for forming the reinforcing member 2PL.

  FIG. 10 is a diagram showing the relationship between the workability and the magnetic permeability for five types of austenitic stainless steel. FIG. 10 shows SUS304 in accordance with JIS standard, SUS304 with increased Ni concentration, SUS304N2, SUS316, and those whose component system is 18% Cr-6% Ni-9% Mn-0.3% N The relationship between the degree of processing and the magnetic permeability is shown.

  Specifically, the relationship between the degree of processing and magnetic permeability according to SUS304 is shown by a curve Cv1 drawn by a one-dot chain line, and the Ni concentration of SUS304 is increased by a curve Cv2 drawn by a solid line The relationship between the degree of processing and magnetic permeability is shown. Further, the relationship between the degree of processing and magnetic permeability related to SUS304N2 is shown by a curve Cv3 drawn by a thick broken line, and the degree of processing and magnetic permeability related to SUS316 are shown by a curve Cv4 drawn by a thick dashed line. The relationship is shown. Further, according to the curve Cv5 drawn with a thick solid line, the component system is 18% Cr-6% Ni-9% Mn-0.3% N (low Ni-Mn, N-added austenitic stainless steel) The relationship between the degree of processing and the magnetic permeability is shown.

  As shown in FIG. 10, SUS316 and the low Ni—Mn, N-added austenitic stainless steel are hardly magnetized by processing. For this reason, as the material of the reinforcing member 2PL, for example, a material that is equal to or more than SUS316 and hardly magnetized by processing may be employed.
