Description

  The present invention relates to a taste inspection method and a bottle taste inspection system for liquid contents in bottles.

Conventionally, a method of measuring the actual weight with a weight checker is considered to have the highest accuracy for performing a taste inspection of a liquid container in a bottle filled with the liquid container.
However, in a facility for filling a bottle with liquid, as the speed increases, it is difficult to measure the actual weight.
Therefore, it has been adopted that an inspection device configured with a camera and a lighting device, etc., picks up a bottle's taste line, measures the height of the taste line, and performs a substitute inspection of the taste amount (for example, Patent Documents). 1).

In addition to glass bottles filled with a liquid container, a method for performing a taste inspection for inspecting the filling amount of the stored liquid container for a bottle 1 such as a resin bottle, and in particular, a polyester frequently used in recent years as the bottle 1 Plastic bottles (PET) made of resin tend to be thinned for weight reduction, and a slight difference in size may occur slightly at the molding stage. Therefore, even if the same amount of liquid container 3 is filled in the bottle 1, the height of the taste line may differ depending on the bottle 1.

  Therefore, in order to provide a product filled with a stable amount of the liquid container 3 even if the size of the bottle 1 slightly changes, it is necessary to perform a taste inspection. .

Correlation is measured in advance to obtain first correlation information. As shown in the measurement graph of FIG. 1, for example, when the cap top height is 310.5 mm, the full capacity varies depending on the change in the cap top height K, such as 2050 ml. The corresponding full capacity is measured in advance.

The minimum filling capacity (B) of the liquid container 3 with respect to the bottle 1 is set by a specified bottle capacity.
The difference T between the height of the taste line and the height of the top of the cap when the bottle 1 is filled with the liquid container 3 reduced by a predetermined amount (HS) from the full volume (A), and the predetermined amount (HS). Correlation is obtained and second correlation information is acquired. As shown in the measurement graph of FIG. 2, for example, when the full volume (A) obtained from the height of the top of the cap is 2050 ml, if the minimum filling volume (B) is 2020 ml, the full volume (A) The difference (HS = A−B) from the minimum filling volume (B) is 30 ml, and the height difference T from the cap top surface height to the taste line height is 36 mm.
Therefore, the allowable minimum taste line height L is 36 mm lower than the top height of the cap, that is, 310.5-36 = 274.5 mm.

  Next, the actual taste line height H of the liquid container 3 in the bottle 1 to be inspected is measured, and the allowable minimum taste line height L is compared with the actual taste line height H to obtain the actual taste line height H. If it is high, it is determined as a non-defective product, and if the actual taste line height H is low, it is determined as a defective product and excluded from the production line.
