CONSTITUTION:When a supporting member 5 for an adhesive tape 4 is mounted on a frame 8 of a packing device, a supporting frame 25 on the side of a holding arm 33 reaches an end on the side of the tape 4 so that the end of the tape 4 is held between a holding member 32 of the frame 25 and a holding roller 33a. Under such conditions, a locking part 9a of an operation lever 9 engages the end of the member 5 so that a press plate 8 fixed to the frame 8 fixes the end of the member 5. When the tape 4 is replaced, if the lever 9 is turned upward, the part 9b of the lever 9 moves apart from the member 5 and the lever 9 makes contact with the end of the arm 33 and turns clockwise so that the tape 4 is applied to a holding part 37 and the member 32 is separated from the roller 33a, so that the member 5 can be drawn out.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing device for agricultural products in which a spherical object to be packed (for example, vegetables such as lettuce and cabbage, or fruits such as melon and apple) is wrapped in a packing sheet.

[0002]

2. Description of the Related Art As a packaging apparatus as described above, for example, there is one disclosed in Japanese Patent Application Laid-Open No. 3-133710. In other words, a packaging table for placing a packaging sheet and having an opening through which a spherical article to be packaged falls is provided, and the packaging sheet is placed on this packaging table and the article to be packaged is dropped into the opening from above. As a result, the packaging sheet is squeezed at the outer edge of the opening, and the object to be packaged is supported by the lower support base while being wrapped in the packaging sheet.

Next, as shown in FIG. 4 of the publication, the support table is lowered to a predetermined position in conjunction with the dropping of the article to be packaged, and as shown in FIGS. 2 and 5 of the publication,
A pair of sandwiching members (12 and 16 in FIGS. 2 and 5 of the above publications) (corresponding to a diaphragm mechanism) that are arranged so as to face each other on both sides advance toward the packaged object, and a pair of sandwiching members. Thus, the upper part of the packaging sheet in the article to be packaged is sandwiched and narrowed down. Next, the upper portion of the packaging sheet sandwiched by the pair of sandwiching members is heated by a heater (see FIG.
It is heated by 0) and melted. Then, by the heating by this cutting, the narrowed upper end portion of the packaging sheet is welded and sealed so that the packaging sheet is not opened, and one packaging is completed.

[0004]

In the above-mentioned packaging device, the packaging sheet is welded and sealed so as not to be opened by heating after cutting the upper portion of the packaging sheet. In this case, the heat during the welding process may be transferred to the packaged item side and damage the packaged item.In recent years, instead of this heat welding process, an adhesive tape has been attached to the upper end portion of the squeezed sheet. It has been proposed to seal the packaging sheet against opening. Such adhesive tape is often wound in a roll shape, and the end of the adhesive tape is pulled out from the roll body by a predetermined length and cut, and the adhesive tape cut to this predetermined length is narrowed down on the packaging sheet. An operation such as sticking to the upper end is performed.

Since the adhesive tape is a consumable item, when this adhesive tape is consumed, it is necessary to replace it with a new adhesive tape. In this case, remove the adhesive tape from the holding unit for temporary holding to which the tip of the adhesive tape is attached, move the cutter for the adhesive tape, and take out the worn adhesive tape from the packaging device, and then Since it is necessary to perform the work of mounting the adhesive tape in the packaging device while performing the reverse operation to the above-described taking-out, there is room for improvement in terms of improving workability in exchanging the adhesive tape. It is an object of the present invention to provide a packaging device that uses an adhesive tape for sealing a packaging sheet, to obtain a structure that facilitates replacement of the adhesive tape and setting of a new adhesive tape in a predetermined state.
