However, in the above conventional structure, for example, when the outer peripheral surface of the packaged crop is a nearly spherical smooth surface, the adhesive tape is surely applied to the outer peripheral surface of the packaged crop. It can be pressed and pasted, but if there is unevenness on the outer peripheral surface of the packaged crop and the adhesive tape application location is concave, the center part of the guide roller rises from the outer peripheral surface of the packaged crop. Since the adhesive tape may not be pressed and fixed, there is a drawback that the adhesive tape cannot be fixed, and there is room for improvement. The present invention aims to eliminate the above-mentioned problems.

The work procedure of the packaging device having the above-mentioned configuration will be described. First, the sheet feeding mechanism 5 sucks one sheet 1 for packaging and moves and feeds it to the working unit 4. Then, when the sheet supply is completed, each of the sheet pressing members 6, 7, 8, 9 simultaneously presses and holds the sheet end portion.
Next, the packaged crop C is placed on the crop holding device 10 in the central portion from above the packaging sheet 1 thus pressed and held.
Artificially insert. At this time, when the packaged crop C is guided by being dropped into the above-described drop space, the sheet 1 is wrapped by the sliding contact resistance between the packaging sheet 1 whose corners are held by the rollers 22 and the packaged crop C. Wraps the lower part of the crop C to be packaged in a state of being strained. Then, the side end portions of the packaging sheet 1 are sequentially covered from the first wrapping tool 11a and guided by the crop C to be packaged. Then, when the guide roller 11c of the third wrapping tool guides the sheet to the vicinity of the upper end, the pressing device 12 operates to hold down, and the holding operation is maintained until the operation of the last wrapping tool 11d ends. After the last wrapping tool 11d covers and guides,
The packaging sheet 1 is adhesively fixed with the adhesive tape t, and the operation is completed. At the time of applying the adhesive tape t, as shown in FIG. 7, even if there is a dent on the outer peripheral surface of the packaged crop C, the central large-diameter portion of the guide roller 16 in the fourth wrapping tool 11d follows the dent portion. The tape pressing operation can be reliably performed.
