Abstract

PURPOSE:To accurately and efficiently measure the diameter side under the lip of a glass bottle by forming a measuring element for a sensor so that it can abuts on the periphery of the part of the glass bottle under the lip. CONSTITUTION:The glass bottle 2 is positioned at a measurement position on a table 1. The sensor 10 has the measuring element 11 fitted previously to a column 7 so as to abut on the periphery of the part 12 under the lip 12 and when the glass bottle 2 is placed on the table 1, the measuring element 11 is directed to the periphery of the part 12 under the lip 12. When a measurement is taken, the measuring element 11 is extruded axially to abut on the periphery of the part 12 under the lip. Here the sensor 10 is suspended through an elastic member 13, so even if the measuring instrument 11 shifts up from the part 12 under the lip 12 to abut on the lip 2a, it moves down along the shape of the lip 2a with the perpendicular component force of a force pressing the lip 2a and abuts securely on the part 12 under the lip 12, thereby accurately measuring the diameter size of the part 12 under the lip.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for measuring the diameter under the lip of a glass bottle, which is capable of automatically measuring the diameter under the lip of a glass bottle using a sensor.

[Conventional technology]

Generally, during the manufacturing process of glass bottles, the glass bottles being manufactured are taken out from time to time, and one person manually applies a caliper or linear gauge under the lip of the glass bottle to measure the diameter under the lip, and the measurement result is If there are variations in the measurement results of the diameter dimension under the lip, resulting in non-standard data and an abnormality is recognized in the process, this will be fed back to the source of the process so that action can be taken early. We carry out high-quality quality control.

[Problem that the invention seeks to solve]

However, quality control in which one person manually applies a caliper under the lip of a glass bottle to measure the diameter under the lip has poor measurement accuracy and measurement efficiency.
There is a problem that high quality cannot be maintained.

Furthermore, when measuring with a measuring device such as a linear gauge equipped with a sensor, there are problems such as the need to adjust the height of the sensor for each measurement due to variations in bottle height.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the problems of the above-mentioned conventional techniques, and to make it possible to accurately and efficiently measure the diameter dimension under the lip of a glass bottle, and to perform high-quality quality control. An object of the present invention is to provide a device for measuring the diameter of the lower lip of a glass bottle.

[Means for solving problems]

In order to achieve the above object, the present invention supports a sensor vertically movably via a guide mechanism on a support provided on a table for placing a glass bottle, and supports the sensor from above via an elastic member. The measuring tip of the sensor is formed so that it can be suspended and abutted near the bottom of the lip of the glass bottle, and the measuring tip can be moved to a measurement position below the lip during measurement. .

[Function] According to the present invention, a glass bottle is placed on a table with the mouth opening facing upward, and the probe of the sensor is placed near the bottom of the lip of the glass bottle. At this time, since the sensor is suspended from above by an elastic member, its contact point moves up and down to follow the shape of the lip, and the contact point automatically and reliably contacts the bottom of the lip, ensuring accuracy. Good measurements can be taken.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the lip lower diameter dimension measuring device according to the present invention will be described with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 designates a table, on which a glass bottle 2 is placed with its mouth opening 3 facing upward. The glass bottle 2 is positioned at a measurement position on the table 1 via a vacuum device (not shown) or the like.

A support 7 is installed upright on the table 1, and a guide member 8 having a guide groove (not shown) in the longitudinal direction is provided in the second part of the support 7.
A movable plate 9 having a convex portion (not shown) that is slidable in the guide groove is supported on the guide member 8 so as to be vertically movable. Bearings (not shown) are interposed between the guide member 8 and the movable plate 9, and these constitute a guide mechanism. A sensor 10, such as an air micrometer, is horizontally attached to the movable plate 9, and a measuring element 1 that can be freely expanded and contracted in the axial direction is attached to the tip of the sensor 10.
1 is installed. The measuring tip 11 is formed so as to be able to come into contact with the lower lip 12 of the glass bottle 2, and the measuring tip 11 is a cylindrical body having a relatively small diameter, for example, a diameter that fits the curved portion of the lower lip 12. Preferably, the cylindrical body is mounted horizontally on the tip of the sensor so that its axis is orthogonal to the axis of the sensor. Usually, the bulge 2a at the upper end of the mouth of the glass bottle 2 is called a lip, and the constriction below this lip 2a is called a lower lip 12.

On the other hand, the sensor 10 is suspended from above via an elastic member 13 such as a coil spring, and the lower end of the elastic member 13 is fixed to the movable plate 9 and the upper end to the stop plate 15.

Further, the stop plate 15 is fixed at a position vertically above the movable plate 9 with screws or the like. The spring force of the elastic member 13 is appropriately selected, and this spring force is set so that the measuring element 11 can freely move up and down along the shape of the curved portion at the lower part of the lip 2a.

Next, the operation of this embodiment will be explained.

During manufacturing, the glass bottle 2 is taken out at any time, placed on the table 1, and positioned at a measurement position on the table 1 by a vacuum device (not shown). The sensor 10 is attached in advance to the support 7 so that the measuring tip 11 comes into contact with the vicinity of the lower lip 12, and when the glass bottle 2 is placed on the table 1, as shown in FIG. Then, the probe 11 is directed near the lower lip 12.

Next, the diameter dimension of the lower lip 12 is measured. Second
As shown in the figure, the probe 11 is pushed out in the axial direction and comes into contact near the lower lip 12. Here, the length of the glass bottle 2 varies by approximately ±1 mm, and the length of the glass bottle 2 varies by approximately ±1 mm.
1 is likely to come into contact with the lower lip 12 with a shift either upward or downward. According to the present invention, since the sensor 10 is suspended from above via the elastic member 13, even if the probe 11 is tilted upward from the lower lip 12 and comes into contact with the lip 2a (same as (shown as a solid line in the figure),
This measuring element 11 moves downward along the shape of the lip 2a due to the vertical component force of the force pressing the lip 2a,
The diameter dimension of the lower lip 12 can be accurately measured by reliably contacting the lower lip 12 (indicated by a broken line in the figure).

〔Effect of the invention〕

Since the present invention is configured as described above, it is possible to accurately and efficiently measure the diameter dimension under the lip of a glass bottle, and it is possible to perform quality control of high-quality glass bottles.
