Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The inspection apparatus according to the present embodiment can inspect whether or not the ring-shaped part to be inspected is a regular ring-shaped part having an inner diameter of a predetermined dimension. As shown in FIGS. It is mainly composed of a main body 1, a light projecting means 3, a light receiving means 4, and a sequencer 5 (see FIG. 8) as a judging means constituting a detection device.

  There are two ring-shaped parts to be inspected: a ring-shaped part R1 (see FIG. 4) with an inner diameter dimension α and a ring-shaped part R2 (see FIG. 5) with an inner diameter dimension β. The inner diameter dimension β of the ring-shaped part R2 is set larger than the inner diameter dimension α of the ring-shaped part R1. These ring-shaped parts (R1, R2) are all made of an annular member having elasticity, and are used as a sealing material such as packing by being assembled in a desired apparatus or equipment, for example.

  The inspection apparatus main body 1 is capable of inserting ring-shaped components (R1, R2) to be inspected, and a plurality of insertion portions (1a, 1b, 1c) having different outer diameters are formed, and the insertion portion ( 1a, 1b, and 1c) are formed so that the outer diameter dimension gradually increases from the tip end a toward the base end b. The inspection apparatus main body 1 according to the present embodiment is composed of a rod-shaped member fixed with the tip a facing upward, and can be dropped by its own weight while inserting the ring-shaped components (R1, R2) to be inspected. .

  More specifically, the inspection apparatus main body 1 has a base end b side fixed to a base 2 made of a plate-like member, and extends substantially vertically upward with respect to the base 2. Further, the inspection apparatus main body 1 has a flat portion c on the base end b side, and the base of the inspection device main body 1 is brought into contact with the flat portion c by abutting the tip of a screw n screwed to the base 2. 2 while being positioned. Note that the tip end a of the inspection apparatus main body 1 is formed in an upwardly convex arc shape, and has a shape that allows easy insertion of ring-shaped parts (R1, R2).

  Further, in the present embodiment, the insertion portion 1a has an outer diameter dimension that is substantially the same as the inner diameter (dimension α) of the ring-shaped component R1 (however, strictly speaking, the inner diameter dimension α so that the ring-shaped component R1 can be inserted). The outer diameter dimension is slightly smaller, and the insertion portion 1b has an outer diameter dimension substantially equal to the inner diameter (dimension β) of the ring-shaped component R2 (however, strictly speaking, the ring-shaped component R2 can be inserted). The outer diameter is slightly smaller than the inner diameter β.

  Here, in the present embodiment, the ring-shaped components R1 and R2 that can be assembled to a desired apparatus or device are set as a ring-shaped component R2 for convenience, and this is designated as “regular ring-shaped component R2” (predetermined dimensions). It shall be called a regular ring-shaped part R2) having an inner diameter of β. The insertion portion 1b among the plurality of insertion portions (1a, 1b, 1c) is referred to as a “normal insertion portion 1b” in which the outer diameter dimension is substantially the same as the inner diameter of the normal ring-shaped component R2.

  Furthermore, the inspection apparatus main body 1 according to the present embodiment is formed in a tapered shape between adjacent insertion portions (between the insertion portion 1a and the insertion portion 1b and between the insertion portion 1b and the insertion portion 1c). Yes. That is, the outer peripheral surface of the insertion portion 1a and the outer peripheral surface of the insertion portion 1b are formed to be connected substantially linearly, and the connected portion is a tapered portion t1, and the outer peripheral surface of the insertion portion 1b. And the outer peripheral surface of the insertion part 1c are connected in a substantially straight line, and the connected part is a tapered part t2.

  Accordingly, when the ring-shaped component R1 is dropped by its own weight while being inserted from the tip end a of the inspection apparatus main body 1, the ring-shaped component R1 passes through the insertion portion 1a, and thereafter, as shown in FIG. It is caught at t1, and further falling is restricted and stops at that position (tapered portion t1). On the other hand, when the normal ring-shaped component R2 is dropped by its own weight while being inserted from the tip a of the inspection apparatus main body 1, the normal ring-shaped component R2 passes through the insertion portion 1a and the taper portion t1, and further passes through the insertion portion 1b. After passing, as shown in FIG. 7, it catches at the taper part t2, and further fall is controlled and stops at that position (taper part t2).

  Furthermore, the inspection apparatus main body 1 according to the present embodiment transmits light to a position that can be caught according to the inner diameter of the ring-shaped parts (R1, R2) (the positions of the tapered portions t1, t2 in the present embodiment). Possible transmission holes (h1, h2) are formed, respectively, and inspection is performed by the detection device using these transmission holes (h1, h2). Such a detection device detects at which position the ring-shaped component (R1, R2) to be inspected inserted into the inspection device main body 1 is caught, and is a photoelectric sensor having a light projecting means 3 and a light receiving means 4. And a sequencer 5 (determination means) (see FIG. 8) electrically connected to the light projecting means 3 and the light receiving means 4 via the wiring cords C1 and C2.

  The light projecting unit 3 and the light receiving unit 4 are capable of detecting transmitted light by irradiating light to the transmission holes h1 and h2 formed in the inspection apparatus main body 1. In the present embodiment, the light projecting unit 3 and the light receiving unit 4 are fixed to the base 2. Two frames are fixed to each of the frames f1 and f2. More specifically, the pair of light projecting means 3 are fixed at positions facing the transmission holes h1 and h2 in the frame f1, and the pair of light receiving means 4 are positioned at positions facing the transmission holes h1 and h2 in the frame f2. The light emitted from the light projecting means 3 is received by the light receiving means 4.

  The sequencer 5 (determination unit) constitutes a determination unit that detects that the transmitted light between the light projecting unit 3 and the light receiving unit 4 is blocked, and the ring-shaped components (R1, R2) are pulled by the determination. The hung position can be specified. That is, when the ring-shaped component R1 is caught by the taper portion t1, the transmission hole h1 is blocked by the ring-shaped component R1, so that the transmitted light passing through the transmission hole h1 is shielded, and the taper portion t1 is blocked. It is possible to detect that the ring-shaped component R1 has been caught, and when the regular ring-shaped component R2 is caught by the tapered portion t2, the transmission hole h2 is blocked by the regular ring-shaped component R2, so that the transmission hole h2 It is possible to detect that the transmitted light passing through is blocked and the normal ring-shaped component R2 is caught by the tapered portion t2.

  Therefore, when it is detected that the ring-shaped member to be inspected is caught on the tapered portion t1, it can be determined that the ring-shaped member R1 is not the regular ring-shaped component R2, and the ring-shaped member to be inspected is the tapered portion t2. When it is detected that it has been caught, it can be determined that it is a regular ring-shaped component R2. Based on the above determination, it is inspected whether or not the ring-shaped part to be inspected is a regular ring-shaped part R2 having an inner diameter of a predetermined dimension β, and the result is displayed on the display means 6 as shown in FIGS. Displayed.

  As shown in FIGS. 8 and 9, the display means 6 is electrically connected to the sequencer 5 and has a frame f3 fixed at a desired position as a casing. A reset button 6c including lamps 6a and 6b and a push button is provided. When it is determined that the ring-shaped component to be inspected is the regular ring-shaped component R2 having the inner diameter of the predetermined dimension β, the indicator lamp 6b is turned on and the ring-shaped component to be inspected is the regular ring-shaped component R2. If it is determined that it is not, the indicator lamp 6a is turned on.

  When the indicator light 6b is turned on, it is grasped that the inspection object is the normal ring-shaped part R2, and therefore the normal ring-shaped part R2 is removed from the inspection apparatus main body 1 by the operator and is an assembly object. When the indicator lamp 6a is turned on while being assembled in the apparatus or device, a predetermined warning (an output from a separate warning lamp or alarm device, etc.) is made. The warning is stopped on condition that the reset button 6c is pressed.

  According to the embodiment, the ring-shaped parts (R1, R2) to be inspected can be inserted, and a plurality of insertion portions (1a, 1b, 1c) having different outer diameters are formed, and the insertion portion (1a, 1b, 1c) comprising an inspection apparatus main body 1 formed so that the outer diameter dimension is gradually increased from the distal end a toward the proximal end b, and at least of the plurality of insertion portions (1a, 1b, 1c) One is a normal insertion portion (in this embodiment, the insertion portion 1b) having an outer diameter that is substantially the same as the inner diameter of the normal ring-shaped component R2, and thus is a normal ring-shaped component R2 having an inner diameter of a predetermined dimension β. It is possible to inspect whether or not accurately.

  Further, the inspection apparatus body 1 is composed of a rod-like member fixed with the tip a facing upward, and can be dropped by its own weight while inserting the ring-shaped parts (R1, R2) to be inspected. The ring-shaped parts (R1, R2) can be inspected by using them, and a simpler apparatus configuration can be obtained. Furthermore, since the inspection apparatus main body 1 is formed in a tapered shape between adjacent insertion portions (between 1a and 1b and between 1b and 1c), a ring-shaped component ( R1 and R2) can be inserted more smoothly and workability can be improved.

  Furthermore, since the ring-shaped parts (R1, R2) to be inspected are made of an annular member having elasticity, it can be easily applied to an inspected object whose internal diameter is difficult to measure using a general-purpose measuring means. Inspection can be performed with high accuracy. In the present embodiment, the regular ring-shaped part is the ring-shaped part R2 having the inner diameter dimension β, but may be the ring-shaped part R1 having the inner diameter dimension α. The insertion portion is the insertion portion 1a, and when the inspection target is caught by the taper portion t1, it is determined to be a normal ring-shaped component.

  Further, according to the present embodiment, since the detection device for detecting at which position the ring-shaped component (R1, R2) to be inspected inserted through the inspection device main body 1 is caught is provided with higher accuracy and easier. Inspection is possible. In particular, in the present embodiment, transmission holes (h1, h2) that can transmit light are respectively formed at positions that can be caught according to the inner diameter dimensions of the ring-shaped parts (R1, R2), and the detection device includes: A light projecting means 3 and a light receiving means 4 capable of detecting the transmitted light by irradiating the transmitting holes (h1, h2) with light, and a sequencer 5 (determining means) for detecting that the transmitted light is shielded. In addition, since the position where the ring-shaped parts (R1, R2) are hooked can be specified by the determination by the determination means, it is possible to perform a further highly accurate and easy inspection.

  Although the present embodiment has been described above, the present embodiment is not limited to this. For example, the inspection apparatus main body may be fixed sideways, and the ring-shaped component to be inspected may be inserted from the tip. . The inspection apparatus main body 1 according to the present embodiment has three insertion portions and two types of inspection objects (ring-shaped components R1 and R2). However, there are two or more insertion portions. It is possible to form three or more types of inspection objects.

  Furthermore, in this embodiment, the space between adjacent insertion portions is formed in a taper shape, but may be formed in a step shape instead of the taper shape. Moreover, although the ring-shaped components (R1, R2) as inspection targets according to the present embodiment are made of an annular member having elasticity, they may be an annular member having no elasticity. Furthermore, in the present embodiment, a detection device for detecting at which position the ring-shaped component (R1, R2) to be inspected inserted into the inspection device main body 1 is caught is provided. It is good also as what inspects visually and in which position it caught. Note that the detection device may have another form (however, a non-contact type is preferable).
