METHOD AND DEVICE FOR MONITORING GOB ARRIVAL TIMING IN I.S. MOLDING MACHINE
In order to accurately detect the timing at which a gob arrives at a rough mold and to reliably reject defective products produced as a result of deviation in arrival timing, a laser sensor is arranged in a manner such that the optical axis passes through the passage of the gob between the exit of a deflector and a rough mold in each section of an I.S. molding machine. A processing means that processes the light blockage signal of the laser sensor detects the gob arrival timing in each section on the basis of the light blockage signal of the laser sensor, and actuates a rejection means to reject the molded product made from said gob if said arrival timing is outside a predetermined range.
Provided is a cylindrical bottle opener with which a crown cap can be safely and easily opened. The cylindrical bottle opener comprises: a crown cap engagement portion formed by cutting off a portion of a cylindrical body; a fulcrum portion formed on an upper side of the crown cap engagement portion; and an engagement claw portion formed on a lower side of the crown cap engagement portion. At least a part of the cylindrical body has a super oval portion having a super oval shape in a horizontal section, and the crown cap engagement portion is formed by cutting off a portion of the super oval portion. The fulcrum portion and the engagement claw portion are formed at portions of the super oval portion having the maximum radius of curvature. Since the fulcrum portion and the engagement claw portion have a very large radius of curvature, when opening a crown cap with the bottle opener, the bottle opener may not be easily shaken and thus glass at the bottle mouth can be protected.
The present invention is capable of performing the operation of removing a crown cap by a cylindrical cap opener stably and easily. A cylindrical cap opener wherein a cylindrical main body is notched to open a crown cap engagement portion, fulcrum points are formed on the upper side of the crown cap engagement portion, and an engagement claw is formed on the lower side of the crown cap engagement portion, so that the two fulcrum points projecting downward are provided on the upper side of the crown cap engagement portion and the lower side is deformed inward. Because of the two fulcrum points, the cap opener is stable and does not easily move during the cap opening operation. Because the lower side is deformed inward to increase the curvature radius in the planar view of the engagement claw, when the crown cap engagement portion engages a crown cap, the portion of the engagement claw engaging the crown cap becomes wider, and thus, the engagement claw (15) is not easily disengaged from the crown cap (7) during the cap opening operation.
This glass bottle forming method reduces the occurrence of defective products by facilitating the removal of air from inside a cavity of a blank mold when a gob has been introduced such that air does not remain in the cavity when settle blowing has been performed.

The present invention addresses the problem of providing a method for manufacturing bottles with a narrow mouth without creating a bead, easily and at low cost, when manufacturing a plurality of types of bottles having the same body shape with different mouth diameters. A plurality of types of mouth molds corresponding to the shapes of the mouth of the glass bottles to be formed are prepared. Also prepared are a plurality of types of neck moldings having a neck molding face corresponding to the shapes of the neck of the glass bottles to be formed in a rough mold and a finish mold which have a two-part cylindrical shape on which a half-doughnut-shaped notch is formed on the upper edge of each half. The half-doughnut-plate-shaped neck moldings, the inner peripheral surfaces of which are the neck molding face, are removably attached to the notches. The present invention solves the above problem by forming glass bottles using a mouth mold selected corresponding to the shape of the mouth and neck of the glass bottle to be formed as well as a rough mold and a finish mold to which the neck molding is attached.
By means of the present invention, it is possible to highly precisely detect so-called defects and so-called top waves where a portion of the top surface of a bottle mouth section dimples in a wavy shape. Two points (A, B) on the top surface of the bottle mouth section are detected from an image of the mouth section captured by an imaging means, the line segment (c) having points A and B at both ends is determined, the point (D) of intersection between the top surface of the mouth section and a vertical line (d) passing through any given intermediate point (C) of the line segment (c) is determined, the difference (T) between the point (D) of intersection and the intermediate point (C) is calculated, and whether the glass bottle is satisfactory or not is determined on the basis of the value of T. If there is a top wave at the top surface of the bottle mouth section, the difference between the intermediate point (C) of the line segment (c) and the point (D) of intersection of the vertical line (d) passing through C and the top surface of the bottle mouth section increases, and so by calculating the difference (T) between C and D, it is possible to determine if T is within a predetermined range that the product is satisfactory, and otherwise that the product is defective having the defect of a top wave.
By means of the present invention, it is possible to accurately inspect for obliquity of the top surface of the mouth section of a bottle even if the bottle is tilted or wobbles while being rotated on an inspection platform. Two points (G, H) on the top surface of the bottle mouth are detected from an image of the mouth section captured by a bottle mouth section imaging means, and at the same time two points (M, N) of the bottom end of the bottle are detected from an image of the foot section captured by a foot section imaging means. The tilt of the two foot section points (M, N) is cancelled from the tilt of the two mouth section points (G, H), and thus the top obliquity in the vertical state of the bottle is calculated, resulting in an accurate inspection of the obliquity of the top surface of the bottle mouth section even when the bottle is tilted or wobbles.

The amount of an alkali eluted from the inner face of a glass container can be largely reduced compared with the existing cases. Under heating, the inner face of a glass container is treated with one or more kinds of gases selected from among sulfurous acid gas, sulfur trioxide gas, chlorine gas and Freon gas. After gradually cooling, a polysilazane solution is applied to the inner face of the glass container, dried and then sintered to thereby form a silicon dioxide coating film on the inner face of the glass container. Owing to the synergistic effects of the treatment with, for example, the sulfurous acid gas and the treatment with polysilazane, the amount of an alkali eluted from the inner face of the glass container is largely reduced compared with the existing cases.
The amount of alkali that elutes from the inside surface of a glass container to liquid inside the container is reduced by preventing foaming, which occurs during sintering, of polysilazane that is applied to the inside surface of the glass container. It is possible to prevent foaming of polysilazane during sintering and to reduce the amount of alkali that elutes from the inside surface of the glass container by treating the inside surface of a glass container by means of: a step for coating the inside surface of a glass container with a polysilazane solution; a step for drying the polysilazane while rotating the glass container that has been inverted and inclined at a 50º to 70º angle; and a step for sintering the polysilazane.

METHOD AND DEVICE FOR INSPECTING DEFECT OF SIDE FACE AT MOUTH OF CONTAINER
[PROBLEMS] A method and a device for automating inspection of the side face at the mouth of a container with high precision. [MEANS FOR SOLVING PROBLEMS] Light is projected to the side face at the mouth of a rotating container, and the transmitted light is received by means of a line sensor directing toward the longitudinal direction. If the data A taken in by each line of the line sensor has a part larger than the crease/streak judgment value (TAL), that data A and the data B taken in by a line ahead of that line by a predetermined difference interval (FP) are subjected to differential processing in an inspection gate, and the number of elements of data where the difference data is larger than a predetermined difference threshold (TH1) is determined. This operation is repeated by a predetermined number of times (VS1) of difference processing and when the total number of elements of difference, i.e. the total sum of the number of elements at the end of the number of times (VS1) of difference processing, is larger than a predetermined threshold (PXL1) of the number of difference elements, a decision is made that there is a defect of crease/streak.

MODULE HAVING LIGHT-EMITTING ELEMENT AND OPTICAL FIBER COUPLED THEREIN, AND COMPONENT FOR MODULE HAVING LIGHT-EMITTING ELEMENT AND OPTICAL FIBER COUPLED THEREIN
A module having a light-emitting element and an optical fiber coupled therein, in which alignment from the light-emitting element to the optical fiber is facilitated to simplify assembly work of the module and which is reduced in size. A through-hole is formed in an end face of a tubular casing having inside the light-emitting element installed. An optical fiber component is formed by fusing a second GRIN lens to the head of the optical fiber and then further fusing a first GRIN lens having a larger numeral aperture to that head. Then the optical fiber component is inserted into the casing from the through-hole such that the optical fiber head faces the light-emitting element in the casing, and the component is fixed by fixing means. After that the through-hole is sealed.
