DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass bottle with an improved model number indicating code for a molding die attached to the bottom of a bottle, and more particularly to a glass in which display information is enriched by changing the shape of the code. About bottles.

[0002]

2. Description of the Related Art The demand for glass bottles used for supplying bottled foods and beverages is increasing as return containers in the future. On the bottle producer side, when providing glass bottles as new to the beverage supplier side, quality control is necessary in order to conform to standards such as safety and standards. In this case, the quality is greatly affected by the consumption of the molding die and the like. Therefore, conventionally, generally, a model number indicating code (bar code or the like) indicating the model number of the mold is attached to the bottom of the bottle,
The model number can be determined by photoelectric detection means or the like.

On the other hand, on the food supplier side, items such as durability are checked for a large number of bottles including the collected glass bottles produced each year. In this case, in particular, the production year is a reference item with a large useful life of the glass, and the discarding processing can be easily determined only by knowing this.

Heretofore, as means for detecting the production year of a glass bottle, the bottle producer has taken measures such as separately adding various other codes different from the above-mentioned model numbers.

[0005]

However, adding both a model number and another code different from this to each glass bottle imposes an extra burden on the bottle producer with extra molding members and steps. In addition, cost increases due to an increase in processing time and the like.

On the other hand, on the food supplier side, the actual situation is that durability tests and the like are performed by using a unique technology without necessarily cooperating with the bottle supplier side.
In that case, the model code formed on the glass bottle may be an obstacle, but it is also a fact that the food supplier also spends extra cost for introducing its own technology for durability testing etc. .

The present invention has been made in view of the above circumstances, and has as its object to include a model number and other control items in one common code, form the bottom of the bottle, and form the molding surface. To provide a glass bottle that can reduce the burden on both sides of the bottle supplier and the food supplier, and thus reduce the cost by making the same code available for both the model number inspection and the quality inspection, etc. It is in.

[0014]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a glass bottle forming machine.
The glass bottle forming machine includes an upper funnel 5, a gob deflector 7, and a gob deflector 7 for guiding a gob (glass lump) G supplied from the gob supply device 1 and cut by the shear 3 downward.
A lower funnel 9, a scoop 11, a trolley 13, a deflector 15, and the like are provided. A rough mold 17 is arranged below the deflector 15, and a gob G guided to the rough mold 17 is pressed by a plunger (not shown) to form a parison P.

The parison P formed by the rough mold 17 is
The mouth is gripped by the mouth mold 19, and the mouth mold 19 is rotated clockwise in the figure by the invert mechanism 21 to be inverted on the finishing mold 23. In the finishing die 23, a glass bottle 25 is formed by blow molding. The glass bottle 25 is rocked and conveyed via a take-out mechanism 27, and is transferred onto a cooling dead plate 29.

Then, the sheet is extruded from the dead plate 29, transferred onto a conveyor 31, and
Is sent to a cooling furnace (not shown).

FIG. 2 is a side view showing a cross section of the glass bottle 25 thus formed, and FIG. 3 is a schematic bottom view thereof. As shown in FIGS. 2 and 3, the bottle bottom 25 a of the glass bottle 25 has a spherical raised bottom structure, and a plurality of barcode-shaped symbols 32 are formed on the lower surface thereof in a convex shape. A plurality of these symbols 32 are arranged at substantially equal intervals along a virtual circular locus R having a constant radius from the center O of the bottle bottom, and each is an ellipse or an ellipse having a major axis in the radial direction.

FIG. 4 is a schematic sectional view showing the bottle bottom forming surface 23a in the finishing die 23. As shown in FIG. 4, a plurality of forming grooves 33 for forming a convex code 32 are provided on the bottle bottom forming surface 23 a of the finishing die 23.

FIGS. 5 to 8 are explanatory diagrams of the functions of the glass bottle 25 with reference numeral 32. In the present embodiment, the model number of the finishing mold 23 formed from the glass bottle 25 is identified by the presence or absence of each symbol 32 formed on the glass bottle 25, and the production year of the glass bottle 25 is determined by the shape change of each symbol 32. Identify.

FIG. 5 is an explanatory diagram of reference numerals for identifying the model numbers. The description will be made on the assumption that the shape of each reference numeral 32 is the same. This figure 5
As shown in the figure, for example, twelve symbols 32 are arranged at substantially equal intervals along a virtual circular locus R having a constant radius from the center O of the bottle bottom, and are roughly divided into first symbols 32a (stop codes). A second code 32b (start code) attached at a position at least about 1/4 turn away from the first code 32a
And a plurality of model number indicating codes 32c to 32l provided at substantially equal intervals during the remaining approximately ／ of the circumference from the second code 32b to the first code 32a.

The second code 32b (start code) is
It is used as an inspection start identification code at the time of inspection by a photoelectric detector (not shown), and the first code 32a (stop code) is used as an inspection end identification code. Each of the model number display codes 32c to 32l is sequentially turned counterclockwise from the second code 32b (start code) to 2 ⁰ (= model number 1),
2 ¹ (= model number 2), 2 ² (= model number 4), ... 2 ⁹ (= model number 5
As in 12), it represents a numerical value that progresses exponentially and is used as a model number code.

Specifically, in FIG. 5, among the reference numerals 32, the blackened reference numerals indicate those formed in a convex shape. On the other hand, the white symbols do not have any protrusions, and are flush with the bottle bottom (no symbols are formed). In the example of FIG.
Since c (2 ⁰ = model number 1) and 32 g (2 ⁴ = model number 16) are outlined, the total (1 + 16 = model number 17) is the model number, and the glass bottle is formed by the finishing mold 23 of the model number 17. It means that it was done. Therefore, the use model number can be determined by detecting the presence or absence of the model number display code by a photoelectric detection unit (not shown). That is, at the time of inspection, for example, while the glass bottle 25 makes one rotation, the second code 32b
Scan from the (start code) counterclockwise in FIG.
The presence or absence of the model number display codes 32c to 32l is detected, and the processing ends with the first code 32a (stop code). Thereby, the used model number can be determined.

Next, FIG. 6 is an explanatory diagram as an identification code including the year of production. As shown in FIG. 6, in the present embodiment, a virtual circular locus R
The length from the center to the radial direction is changed so that the model number display code 32 is also used as the production year display code.

That is, in FIG.
... 32l are second symbols 32 along the virtual circular locus R.
From the b side, it is divided into two skipping sections (A, B, C, D, E). These divisions (A... E) correspond to the second code 32
b (start code) 2
Exponentially progresses as ⁰ (= production year 1), 2 ¹ (= production year 2), 2 ² (= production year 4), 2 ³ (= production year 8), 2 ⁴ (= production year 16) Represents the numerical value to be used. The length of at least one of the two model numbers 32c... 32l provided in these sections (A... E) is increased in the radial direction. This is used as the production year code. Note that at least one of the meanings is because, in the case of eliminating the projection formation as the model number indicating code, it is necessary to perform the same using another code. Therefore, for a code having no model number display function, both codes of one section may be changed in length. In FIG. 6, such a display is made (see 32i and 32j).

Specifically, in FIG. 6, the model numbers 32d (2 ⁰ = production year 1), 32i, 32j of the sections A and D
(2 ³ = production year 8), and the length of the second code 32b is large, so that the total (1 + 18 + 1 = production year 20) is the production year, and the glass bottle is subjected to photoelectric detection means (not shown). For example, it is determined that it was produced in 2020.

In the example of FIG. 6, as in the case of FIG. 5, the reference numerals 32c (2 ⁰ = model number 1) and 32g (2 ⁴ = model number 16) are outlined, and their totals ( 1 + 16 = model number 17) becomes the model number, and it is simultaneously determined by the photoelectric detecting means that the glass bottle is formed by the finishing mold 23 of the model number 17.

FIG. 7 shows another example. In this case, the model number 17 and the production year 20 are set in the same manner as in FIG.
It is determined to be 10 years. 8 is also the same, and it is determined that the model number is 16 and the production year is 2000. As described above, it is possible to determine the model number and the production year based on the combination of the codes representing the even numbers and the odd numbers.

Therefore, according to the present embodiment, the model number and other management items are included in one common code 32 and are formed at the bottom of the bottle. There is no need to separately add a different code, and no extra molding member or process is imposed on the bottle producer, thereby reducing the processing labor and the cost.

Further, the food supplier does not need to carry out a durability test or the like by using a unique technique, and the model code 32 formed on the glass bottle 25 can be effectively used. There is no need to spend extra management costs on inspections and the like.

Accordingly, the molding surface can be rationalized, and the same reference numeral can be used for both the model number inspection and the quality inspection, so that the burden on both sides of the bottle supplier and the food supplier can be reduced, and the cost can be reduced. Can be achieved.

In the above-described embodiment, the change of the model number display code 32 is a change in the length from the center O of the virtual circular locus R in the radial direction. However, the change is not necessarily limited to this.
Although not shown, for example, the width may be changed along the direction of the circular locus.

Further, in the above-described embodiment, the model number display code 32 is divided into two from the second code 32b along the virtual circular locus R, but may be divided into three. In that case, a third type of display function can be further added.

The dies such as the finishing dies 23 shown in FIGS. 1 and 4 are not necessarily installed at the factory at the beginning of the year, and are replaced at regular intervals such that they are removed at the end of the year. Absent. It is usually used continuously over the year or replaced during the next year.

In view of the above, the production year display code shown in FIGS. 5 to 8 needs to be moved down by one year. It is desirable from the viewpoint of work efficiency and economy.

Therefore, in the present embodiment, the code that functions as the production year display is longer than the code that functions as a simple model number display code. The production year is formed in a convex shape protruding from the bottom of the glass bottle 25.
That is, the bottom surface of the finishing die 23 is formed as the forming groove 33. Therefore, a code corresponding to an increase of one year, for example, a code indicating 2 ⁰ = 1 in the section A, can be sufficiently dealt with by performing a cutting process only by enlarging the length of the forming groove 33 of the finishing die 23. And the advantage that workability and economy can be improved can be obtained.

Further, when a mold that has been passed over a year is used for the next year, the code of the section A is not sufficient.
Therefore, in the present embodiment, as shown in FIGS.
First and second codes 32a, 32 other than the model number display code
b can also be used as a production year code (2 ⁰ = production year 1) by changing the length.
As a result, the same mold can be used for a long period of time by simple processing by effectively utilizing all the codes. In this respect, the economic efficiency can be improved.

In the above embodiment, the production year can be managed by changing any one of the model number display codes and reading the change. However, as a management item other than the model number, Can of course be applied as a management item other than the production year.

[0039]

As described above, according to the present invention, the model number and other control items are included in one common code and formed at the bottom of the bottle, so that the molding surface can be streamlined, The same code can be used for both the model number inspection and the quality inspection, and the burden on both sides of the bottle supplier and the food supplier can be reduced, and the cost can be reduced.
