2. Description of the Related Art Paper packaging containers for liquid foods such as milk, juice, green tea, oolong tea, mineral water and other beverages are, for example, packaging laminates with a fibrous base material (eg, paper) / plastic layer. The web-shaped packaging material (paper-based packaging material) with a fold line is formed into a tube by means of a longitudinal vertical line seal, and the tube-shaped packaging material is filled with liquid food, and then packaged in a tube. Apply a horizontal line seal in the transverse direction of the material, first form into a cushion-shaped or pillow-shaped primary shape, and if the packaging material is strip-shaped, cut it individually at regular intervals, fold along the fold line to the final shape Molded. Examples of the final shape include a brick (parallel hexahedron), a polygonal prism exceeding a square, a hexagonal prism, an octagonal prism, a ten-prism prism, and a tetrahedron shape having four triangular surfaces.

Further, in a gable-top (roof type) paper packaging container, a paper packaging material (paper-based packaging material) is cut into a predetermined shape, and blanks sealed in the vertical direction of the container are obtained.
It is obtained by sealing the bottom of the blanks in the filling machine and then filling the milk, juice or other beverage liquid food from the upper opening and sealing the upper part. The appearance design of the packaging container product is printed on the surface of these packaging materials.

[0004] In a production site where the above-mentioned beverage filling machine is used, the operation results of machines of the same type greatly differ depending on the machine use environment or conditions of each production site. Thus, due to the combination of the various elements, the result is not even predictable to the parties. Therefore, at the production site,
In order to grasp the actual situation, operators and managers on site are mobilized to collect and analyze data. This is because the filling machine
It occurs more frequently as it gets older. In addition, in order to accurately grasp the current status of the machine that should be the target of the survey,
It is also necessary to investigate the factors affecting the operation of other machines that follow, and the investigation time / labor may affect the original production operation time.

FIG. 1 is a schematic diagram of an example of a system including a monitoring apparatus that uses a method for monitoring a liquid food packaging and filling machine according to the present invention. FIG. 2 is a schematic view of another example of a system using the method for monitoring a liquid food packaging and filling machine according to the present invention.

A monitoring device 1 according to the embodiment shown in FIG.
Is a liquid food filling machine 2 at least comprising a paper-based packaging material forming station 2a, a liquid food filling station 2b, and a paper container sealing station 2c, and a predetermined monitoring point in the filling machine (in the figure, white points The present invention is directed to a filling machine having a control means 3 for controlling the operation of the filling machine based on a monitoring signal received from the filling machine shown in FIG. From the filling machine, paper packaging containers filled with liquid food, for example,
Tetrahedral containers, brick-shaped containers, roof-type containers, etc. are produced. A feature of the monitoring apparatus 1 according to this aspect is an operation status database 4 in which a monitoring signal is recorded together with a monitoring time, and the operation status database 4 is constructed by recording at least a factor of operation stop, a stop time, and a repair time. Analysis and display means 5 for searching and analyzing accumulated data in the operation status database 4 and display means 6 for displaying at least frequency and time-series sorted data according to the stop factor.

In this embodiment, there is provided a diagnostic means 8 for diagnosing the activated packing and filling machine by comparing the accumulated data with predetermined reference operation data 7 from a standard packaging and filling machine.

In this embodiment, the monitoring apparatus further comprises a prediction means 10 for comparing the accumulated data with predetermined reference schedule data 9 based on a standard packaging / filling schedule to predict future operation by the activated packaging / filling machine. It is. The diagnosis result and the prediction result are displayed on a display unit 6 (not shown).

Hereinafter, the operation will be described in more detail. In this embodiment, analysis / monitoring of the operation status of the filling machine 2 is automatically performed. Specifically, data is directly transmitted from the filling machine sequencer which is the control means 3, or
The monitoring signal is transmitted in parallel with the transmission to the control means. For example, SattBus interface board and Sattbu
s You can apply communication using the I / O driver, and in the case of a normal sequencer GE, you can select Ethernet or a serial port. .

The operation status database 4 can be constructed by, for example, a DDE application SoftLogger which is database generation software. With this software, you can manage all data and record the time and data in a file when the data changes. Timers and temperature monitors are constantly changing,
Always sampled. Note that floating point and the like need not be handled. It is desirable that the data be freely ported to, for example, a general text format or an Excel sheet format so that the data can be freely analyzed. In the analysis search, simply by designating the search period, the data is automatically output in a required format, and the efficiency can be greatly improved.

The number of recorded data is, for example, 40 tags
(1 tag is 16 bits, same as 16 points input / output 16X
40 = 640 points), one tag for both discrete (digital I / O) and analog (16 points)
Zero point panel errors can be covered. For data collection, the raw data of the filling machine sequencer can be captured in a form compatible with the network using a communication cable + PC + USB port + monitor.

FIG. 2 shows a second embodiment. In this embodiment, instead of receiving from only the monitoring signal from one packaging and filling machine 2, the same type of packaging and filling machine 2 ′, 2 ″ in parallel, and the outer packaging machine 2 ″ ′ on the downstream side of the packaging and filling machine. This is an example of a system that receives an external monitoring signal also from 2 ″ ″. Typically, as an external signal,
Up to 16 points can be captured.

In the technical field where the present invention is used, food must be handled and must be food-sanitary. In addition, since liquids are handled, special attention must be paid to leakage and the like.
According to the system of the present invention, the operation status of the packaging and filling machine can be easily grasped by the combination of various elements, even if the machine use environment or condition at each production site is different. In the past, a lot of time and labor was spent on grasping surveys. However, accurate information can be obtained by automatic 24-hour monitoring, so that it can be grasped quickly.

In one embodiment of the present invention, since the monitoring signal is directly obtained from the existing filling machine control means, there is no need to set a measuring device in the middle, and the device can be manufactured at low cost. In addition, since it is not necessary to add a module or change the program of the machine body for data sampling, there is no burden on the filling machine control (such as an increase in scan time).

Due to the features of the above embodiment, it can be applied to different types of filling machines. In addition, by making the data file of the operation status database sharable on a network, it can be seamlessly connected to a network such as a production factory or technical support.

In one embodiment of the present invention, it is possible to predict the future operation by the operating packing and filling machine by comparing the accumulated data with the predetermined reference schedule data based on the standard packaging and filling schedule. The production operation rate can be predicted from the output of the ratio and the countermeasure items, and the appropriate ordering timing of the production material can be made by combining the data with the production plan.
