BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to parts having the same reference shape parts assembled on an assembly line and the like, and parts other than the reference shape part having relatively different shape dimensions, and parts having the same reference shape part on the same surface. The present invention relates to a component shape selection device for selecting and displaying the shapes of a plurality of similar parts which are different in shape dimension other than the reference shape part and which are difficult to be visually discriminated from each other in a very simple and accurate manner.

[0002]

2. Description of the Related Art Conventionally, a reference shape stored in a device is optically compared with an actual part shape, or an identification mark is attached to a different position for each part, and a similar part is detected by detecting the identification mark. A sorting apparatus and a sorting method such as shape sorting are generally used.

[0003]

However, in the conventional example, since the shapes of the parts are selected as described above, the selection device is very expensive, and the identification mark is processed on the parts themselves. There was a problem because it took time and trouble.

The present invention has been made in order to solve the above-mentioned problems of the conventional example, and is extremely low-priced, extremely simple, and capable of selecting a plurality of similar parts and parts having different front and back relative shapes. The object of the present invention is to provide a component shape selection device capable of accurately selecting and identifying the front and back sides of.

[0005]

Therefore, in the component shape selecting apparatus according to the present invention, the reference shape part has the same front and back, and the relative shape other than the reference shape part has different front and back parts, and the reference surface on the same surface. A part shape selecting device for selecting and displaying the shapes of a plurality of similar parts having different shape dimensions other than the shape part, the position determining means for locating the reference shape part of the part to be selected on the device body, and the parts A plurality of pressure detecting means for detecting pressure, a shape detecting means for detecting a shape of a component by arbitrarily combining the pressure detecting means and connecting the circuits, and a display means for identifying and displaying the shape detection result of the shape detecting means. With the provision of (1) and (2), the above object is achieved.

[0006]

In the component shape selecting apparatus according to the present invention having the above-described structure, when the component is set on the positioning means adapted to the reference shape part of the component, a plurality of pressure sensing means provided on the apparatus main body are provided. The pressure sensing means of the component corresponding to the shape of the component detects the component, and the pressure sensing means, which is connected to the circuit in advance so that the shape of the component can be selected, detects the shape of the component. The result is identified and displayed by the display means.

As a result, the front and the back of similar parts which are difficult to be visually identified and the parts of which the relative shapes are different between the front and the back are easily and accurately selected and displayed for identification.

In FIGS. 1 to 5, 1 is a component shape selection device (hereinafter referred to as a checker), 2 is a positioning jig which constitutes a positioning means A for parts, and 3 is a pressure sensing means B 4 A shape detection table (hereinafter referred to as a detection table) provided with the individual pressure-sensitive detection sensors 4a, 4b, 4c, 4d, 5 is a power switch, 6 is a model display lamp, 7 is a model setting switch,
Reference numeral 8 is a green shape selection pass indication lamp (hereinafter referred to as OK indication lamp), 9 is a similar indication failure indication lamp (hereinafter referred to as NG indication lamp), 10 is a cam ring to be sorted, and 10a is a cam ring 10. Reference shape part,
Reference numeral 10b denotes a cam housing hole of the cam ring 10 having different front and back relative shapes, 11 is a belt conveyor (hereinafter, referred to as a conveyor), 12 is a work table, 13 is a component carrier box, and M is an assembly worker or an assembly robot.

(Operation) An operation will be described based on the above configuration. First, the pressure detection sensors 4a and 4c and 4b and 4
d are respectively connected by a wiring board (not shown), and the OK indicator lamp 8 is connected to the circuits of the pressure sensitive sensors 4a and 4c, and the NG display lamp 9 is connected to the circuits of the pressure sensitive sensors 4b and 4d. The shape detecting means C and the display means D for identifying and displaying the shape detection result are formed.

Next, the power switch 5 of the checker 1 is turned on. Then, the model selection switch 7 of the cam ring 10 on the panel is pressed to turn on the model display lamp 7a, and the turned-on model is confirmed.

The operator takes out the cam ring 10 from the transport box 12 carried from the previous process, and puts it on the reference shape portion 2a provided on the positioning jig 2 of the detection base 4 of the checker 1 on the reference shape portion 10a of the cam ring 10. Match cam ring 1
Insert 0 into the positioning jig 2 and check the green O of the checker 1.
Check the lighting of the K display lamp 8. If the red NG display lamp 9 lights up, the cam ring 10 is removed from the detection base 4, turned over, and then inserted again into the detection base 4. Then, after confirming that the green OK indicator lamp 8 is turned on, the cam ring 10 is removed from the detection base 4, and the conveyor 11 is left in the state of being in the normal state.
The assembling work of the cam ring 10 is performed on the pump body P on the work table 12. If the red NG indicator lamp 9 lights up again at this time, the model of the cam ring 10 may be different, so after checking the model indicator lamp 6 that is lit, remove the cam ring 10 and store it separately in a box or the like. To do. In this case, the model indications displayed on the panel surface are all similar parts and indicate similar parts having the same reference shape part 2a but different front and back relative shapes. Table 1 shows an example of turning on / off the pressure-sensitive detection sensors 4a, 4c and 4b, 4d for each type of sorting.
