However, in the above-mentioned conventional structure, since the vertical swing range of the holder is constant, the shape and size of the crop to be packaged depends on the growth situation and the type of crop. If they are different from each other, they may be held too strongly, or the holding operation may be insufficient, resulting in damage to crops or loosening of the packaging sheet after the wrapping operation, and there is still room for improvement. there were. The present invention aims to eliminate the above-mentioned problems.

According to a characteristic configuration of the present invention, in the packaging apparatus described at the beginning, each of the holders is pivotally supported by three holding plates arranged side by side so as to be relatively swingable. A connecting means is provided, and the holding plates on both sides are provided with biasing means for biasing the central holding plate toward the outer side relative to the crop to be packaged, and A point is that a drive mechanism is provided for moving the holding plates on both sides of each of the left and right holders toward and away from the crop to be packaged.

After the packaged crop is placed on the pan in the open position, the left and right holders hold and hold the packaged crop from both left and right sides. When the holding plate is moved to the packaged crop side by the drive mechanism in the abutting state, first, the central holding plate comes into contact with the packaged crop, and when it is further driven, the left and right holding plates that are open-biased are the biasing means. Against the urging force of (1), it swings close to a posture along the outer peripheral surface of the packaged crop and switches to the action posture.
Then, each wrapping tool sequentially performs the wrapping operation of the wrapping sheet while maintaining the holding state.

As a result, even when the shapes of the packaged crops are different, in the working attitude, since the holding plates are always in the attitude along the outer peripheral surface of the packaged crop, the packaging sheet is loose. In the absence of the product, the product was in close contact with the packaged crop, and it was possible to obtain a product with a good packaging finish with little slack. Further, since the central holding plate that first comes into contact with the packaged crop is not directly driven and is held via the biasing force of the biasing means, a strong pressing force is not applied to the packaged crop, Less likely to cause damage. Moreover, since the urging force of the urging means always acts during the sheet covering guide operation by each of the wrapping devices, the sheet can be surely held and the sheet is not loosened.

The operation 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. At this time, the round bar member 33 protects the wrapping sheet 1 from tearing at the upper edge of the holder 30 due to the tension force due to the sliding contact resistance. Then, the left and right holders 30, 30 tighten the crop to be packaged. At this time, as shown in FIG. 3A, first, the central holding plate 20b elastically abuts, and the left and right holding plates 20a and 20c are gradually guided along the outer peripheral surface (see FIG. )reference). Then, the first wrapping tool 11
The side edge of the packaging sheet 1 is sequentially covered from a to cover and guide the crop C to be packaged. Then, after the last wrapping tool 11d is covered and guided, the wrapping sheet 1 is adhesively fixed by the adhesive tape t, and the work is completed.
