Abstract

(57) [Abstract] [Purpose] To facilitate the inspection of polymer material extruded products having notches along the longitudinal direction. [Structure] A groove 20 or a ridge 30 or a pair of ridges 41, 42 or a ridge 51, 5 showing a dimensional error allowable range of a transverse notch end A of a longitudinal notch 15 of an extruded product 10.
2 is provided along the longitudinal direction.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a polymer material extruded product having a notch along a longitudinal direction in a weather strip for automobiles and the like.

[0002]

[Prior art]

 Description will be made with reference to FIGS. Conventionally, when a notch 15 along the longitudinal direction is provided in the extrusion molded product 10, whether or not the notch end A is within a dimensional error allowable range is inspected using an inspection tool. As shown in Fig. 1 and Fig. 2, it is difficult to determine the reference coordinates X-X and Y-Y, and it is difficult to measure the distance Z from the reference coordinates, which causes a problem that a large number of man-hours are required for the inspection. is there. Further, there is a problem that it is difficult to judge whether or not the displacement is in the allowable range at all the positions when the displacement is generated in the longitudinal direction of the extrusion molded product.

[0003]

[Problems to be solved by the device]

 The problem to be solved is that when the notch 15 is provided along the longitudinal direction of the extruded product 10, it is difficult to measure whether or not the transverse notch end A is within the dimensional error allowable range. Therefore, the inspection requires a lot of man-hours.

[0004]

[Means for Solving the Problems]

 Description will be made with reference to FIGS. 3 to 8. A groove 20 or a ridge 30 or a pair of ridges 41, 42 or a pair of ridges 51, 52 indicating a dimensional error allowable range of the transverse cutout A of the longitudinal cutout 15 of the extruded product 10 is provided along the longitudinal direction. It is provided.

[0005]

【Example】

 Explaining the embodiments, 10 is an extruded product such as a weather strip, which is made of a high molecular material, that is, rubber or synthetic resin. Reference numeral 15 denotes a cutout portion which is cut out by cutting a part of the extruded product 10 in the longitudinal direction, and 20 and 30 allow for dimensional error of the transverse cutout end A of the cutout portion 15 provided along the longitudinal direction of the extruded product 10. Grooves and ridges indicating the range, 21 and 31 are allowable upper limits, 22 and 32 are lower limits, and the cross-sectional shape can be changed as necessary. For example, as shown in FIGS. A pair of ridges 41 and 42 indicating the upper limit and the lower limit allowed in the above may be provided, or a pair of recessed ridges 51 and 52 may be provided as shown in FIG.

[0006] Explaining the operation, when the notch A is misaligned, it is out of the dimensional error permissible range due to the groove 20, the ridge 30, the ridges 41 and 42, and the ridges 51 and 52. You can tell them instantly.

[0007]

[Effect of device]

 Since the present invention is configured as described above, when the extruded product 10 is provided with the notch 15 along the longitudinal direction, it is possible to inspect whether the transverse notch end A is within the dimensional error allowable range. It becomes extremely easy, and the number of inspection steps can be significantly reduced.
