Description

  The present invention relates to a packaging machine, a printing inspection method for a packaging bag, and a manufacturing method for a packaged product.

  When manufacturing a packaged product formed by filling the contents in the packaging bag, the production number, the expiration date, or the expiration date is printed on the packaging bag in the case of food. Printing is generally performed in a process separate from printing of the pattern or the like of the entire packaging bag. If the printing is not accurate, it becomes a defective product. Therefore, it is usually inspected before shipping whether the printing is performed accurately.

  Although the print inspection may be performed manually, the load on the worker becomes excessively large, and as a result, there are fears that many inspection errors such as oversight occur. Therefore, in order to perform the print inspection efficiently and accurately, a print inspection apparatus may be provided particularly in a packaging machine that continuously performs processes such as filling of contents and sealing (sealing) of packaging bags.

  For example, as a packaging machine, a feeding device that sequentially positions the packaging bags supplied from the bag feeding mechanism unit via the transport unit on the circumference, and a plurality of processing devices that are arranged corresponding to each positioning position of the feeding device, Are known. In this type of packaging machine, the area in which the above processing device is arranged is called a station, the printing device is arranged in one station, the printing inspection device is arranged in another station, and the other station is filled. A device or the like may be arranged.

  In the packaging machine having such a configuration, it is possible to continuously and automatically perform packaging bag supply, printing, printing inspection, filling, and sealing. In addition, by controlling so as not to perform the filling process according to the determination of the print inspection, it is possible to ensure that the printing of the manufactured packaged product is performed with quality exceeding a certain standard. Note that an inspection method using a camera (imaging device) is generally employed for the print inspection device (see, for example, Patent Document 1).

In the present embodiment, the pair of suction cups 31 adsorb both ends of the packaging bag 3 so that the print 5 of the packaging bag 3 is located between the suction holding positions shown in FIG. Then, as shown in FIG. 5, the turning mechanism unit 30 shifts the pair of suction cups 31 from the suction holding position to the turning-up position. As a result, a part of the packaging bag 3 is turned up obliquely with respect to the transport path 11. Here, the printed 5 is present between the pair of suction cups 31 in the portion of the packaging bag 3 that has been turned up.

  At this time, as shown in FIG. 6, the image of the turned up portion of the packaging bag 3 is imaged by the imaging device 41 of the print inspection device 40. That is, the print 5 of the packaging bag 3 is imaged. In addition, the turning mechanism part 30 is abbreviate | omitted in FIG. The captured image is sent to the determination device 45, and the determination device 45 determines the quality of the print 5. Here, in the present embodiment, if the printing 5 is determined to be good, a bag feeding process by the bag feeding mechanism unit 50 described later is performed, and if it is determined that the printing 5 is defective, The manufacturing process is cancelled. Specifically, the operation of the packaging machine 1 is stopped so that the bag feeding process by the bag feeding mechanism 50 is not performed. In this case, the manufacturing process is resumed after the packaging bag 3 that has been determined to be defective is removed.

  And in the bag supply process by the bag supply mechanism part 50 when it determines with the printing 5 being favorable, as shown in FIG. 7, the bag supply mechanism part 50 is a part of the packaging bag 3 by a pair of suction cups 51.
