Then, as shown in the third section, the packaged object B, which has been weighed by the weighing mechanism 3 and pushed up to the packaging station S by the lifter mechanism 4, is wrapped by the folding mechanism 6 at the packaging station S. However, since two labeling mechanisms 10 and 10 are arranged in parallel directly above the packaging station S, one labeling mechanism 10 prints the product name, price, weight, etc. of the packaged item. It is possible to affix a label C, and then affix a label C with a barcode or the like printed thereon using the other label affixing mechanism 10. In this way, two labels with different contents can be affixed by one weighing, packaging and pricing device. C can be attached to the packaged object B.

Furthermore, each labeling machine [10, 10 is located at the labeling position directly above the packaging station S! In this case, the mode is automatically switched to the automatic pasting mode, and as shown by the chain line in FIG. By simply moving the label pasting position 1 and the front position, the label C can be pasted on the packaged item B by switching between manual and automatic mode using the weighing and packaging labeling device W1. The versatility of the weighing, packaging and pricing apparatus 1 is further improved.

Note that the label C attachment position can be adjusted by moving each label attachment mechanism 10 in the front-rear direction shown by the arrow X in FIG. 3 and adjusting its front-rear position 1.

<Effects of the Invention> As described above, according to the first invention, since the labeling means is movable between the labeling position directly above the packaging position and the retracted position 1 by the support means, the labeling means can be moved between the labeling position directly above the packaging position and the retracted position. In this case, labels are automatically pasted by the label pasting means, and by moving the label pasting means to a retracted position, replenishment and replacement of label sheets, maintenance and inspection of the pasting means, etc. can be carried out extremely easily. This will improve their workability.

Further, according to the second invention, as in the first invention, the label pasting means is movable between the label pasting position and the retracted position, so maintenance and inspection work of the label pasting means, etc. This can be done extremely easily, improving work efficiency, and also making it possible to affix two types of labels with different contents to a packaged item using one weighing, packaging, and pricing apparatus.

Furthermore, according to the third invention, the pasting mode switching means
When the label pasting means is in the pasting position, the pasting mode is switched to automatic pasting mode, and when the label pasting means is in the front position, the pasting mode is switched to manual pasting mode, so that manual pasting is possible. If this is required, the label can be pasted manually by simply moving the label pasting means to the front position, or the label can be pasted automatically when moved to the label pasting position. This means that a single weighing, packaging and pricing device can switch between manual and automatic methods to attach labels to packaged items, further improving the functionality and versatility of the device. .
