Description

Rubber packing width inspection device {Inspection Device for Rubber Packing Width}

The present invention relates to a rubber packing width inspection device. More specifically, it is possible to accurately determine whether a defect is defective by checking the width of each part of the rubber packing and checking if it is wider or narrower than the normal value, and to inspect a plurality of rubber packings. This relates to a rubber packing width inspection device that can be inspected quickly.

In thin-film endless belts used as intermediate transfer materials or transport belts in electrophotocopiers, printers, fax machines, and their multi-function devices, it is necessary to measure the film thickness and check the film thickness widely across the entire belt or object.

Means for measuring such film thickness include, for example, contact sensors (e.g. micrometer, dial gauge, linear gauge, ultrasonic film thickness meter, eddy current film thickness meter, etc.), non-contact sensors (e.g. laser displacement film thickness meter, etc.) etc.).

The conventional belt film thickness measurement as described above has the following problems.

1) It is necessary to stop the object being measured during measurement, and the measurement time increases in order to measure accurately in proportion to the measurement points.

2) With changes in temperature, etc., the characteristics of the measurer change, the frame of the measuring device deforms, the distance between the measurer and the measurement standard changes, and the measurement system deteriorates.

3) In order to maintain measurement precision, it is necessary to frequently calibrate the measurement precision.

Therefore, in order to improve the conventional problem, the technology described in Japanese Patent Application Publication No. 2007-057508 as shown in FIG. 1 was proposed, the technical feature of which is to measure the film thickness of the belt 12. A measuring device (100), comprising a plurality of shafts (14, 16) for rotating the belt (12) and an inner peripheral speed measuring means (20A) for measuring the moving speed of the inner peripheral surface of the rotating belt (12) and the rotating belt (12). The moving speed of the inner peripheral surface of the belt 12 obtained from the outer peripheral speed measuring means 20B and the inner peripheral speed means 20A for measuring the moving speed of the outer peripheral surface of the belt 12, and the moving speed of the inner peripheral surface of the belt 12 obtained from the outer peripheral speed measuring means 20B. It is characterized by providing film thickness calculation means (24) for calculating the film thickness of the belt (12) based on the moving speed of the outer peripheral surface of the belt (12).

However, the technology described in Japanese Patent Publication No. 2007-057508 has the advantage of stably measuring the average thickness of each belt 12, but there is no way to check if the thickness of each part is different. There is a problem in that it is difficult to measure the width of the belt.

Additionally, since the thickness of only one belt can be measured at a time, there is a problem in that it takes a considerable amount of time to inspect multiple belts.

Furthermore, rubber packing, which has a ring shape similar to a belt and is used for sealing purposes, is judged to be defective if the width measured along the circumferential direction is wider or narrower than the error range, so that leakage, etc. does not occur when used in precise places. There is a need to prevent this.

Therefore, the control unit 210 determines whether the rubber packing 400 is abnormal through the sensing distance between the upper or lower surface of the rubber packing 400 received from the upper main sensor 223 and the lower main sensor 224. can do.

That is, in the case of the rubber packing 400, which is used in precise areas rather than ordinary packing, uniformity of width is important, so if it falls outside the set error range, it is judged as defective, thereby preventing defective products from being shipped.

In addition, a seating groove 312 may be formed on the upper outer peripheral surface of the main rotating member 310 constituting the rotating member 300. The rubber packing 400 is placed in the seating groove 312, and the rubber packing 400 is placed in the seating groove 312. A support protrusion 313 is formed at the lower part of the seating groove 312 to prevent the mounted rubber packing 400 from moving downward.

Here, the thickness of the rubber packing 400 may be thicker than the depth of the seating groove 312, and the rubber packing 400 protrudes to the outside of the main rotating member 310, so that the lower main The distance to the protruding part can be detected by the sensor 224.

Since the distance information and the tolerance information are stored, if the detected distance is within the error range, it is judged as normal, and if it is protruding or concave enough to exceed the error range, it is judged as defective.

Therefore, in the present invention, rather than simply measuring the width of each rubber packing 400, if the width is wider or narrower than the error range at least in part, it is judged as defective to prevent errors from occurring when used in a precise location.

Of course, the control unit 210 stores refraction information that is refracted or delay information that delays time when the laser passes depending on the material forming the installation plate 340, so each rubber packing ( By calculating the distance between the upper and lower surfaces of 400), the distance can be calculated more accurately.

Of course, when the control unit 210 completes the inspection of the rubber packing 400 installed on one auxiliary rotating member 330, the main rotating member 310 is rotated at a predetermined angle and placed on the next auxiliary rotating member 330. By inspecting the rubber packing 400, multiple rubber packings 400 can be inspected more quickly.

Of course, as described above, the installation plate 340 is made of a transparent material that allows lasers and the like to pass through.
