2. Description of the Related Art Heretofore, in the case of body roll packaging of a roll to be wrapped, the raw material roll is rewound in the width direction of the roll to be wrapped, developed and cut into a length suitable for the width dimension of the roll to be wrapped. It is formed into a packaging material piece, and the packaging material piece is transported to the center in the width direction of the roll to be wrapped, and subsequently sent out toward the roll to be wrapped in a direction orthogonal to the transfer method. Is involved. When stronger protection of the roll is required, two types of packaging materials having different characteristics, such as foamed polyurethane laminated paper as the inner packaging material and polyethylene laminated kraft paper as the outer packaging material, are used. Heavily wraps the roll to be wrapped.

FIG. 4 shows an outline of a conventional apparatus used for such double-roll packaging, and a rewinding apparatus for different types of raw material rolls 2 and 2 'on the left and right sides with a packaging material transporting conveyor 1 at the center. 3, 3 ', the feeding devices 4, 4' and the cutters 5, 5 'are arranged. First, the raw material roll 2 used on one side is rewound, unfolded and cut by the cutter 5. The roll is sent to the left in the figure, transported to the center position (C-C) in the width direction of the roll to be wrapped, sent out toward the roll to be wrapped R in a direction perpendicular to the arrow, and wrapped. Next, the outer packaging material roll 2 'is continuously unwound and unrolled, and cut in the same manner with the cutter 5' to cut the packaging material piece to the right in the drawing, at the center position (C in the width direction of the roll R to be packaged). -C) and roll R to be wrapped in the right angle direction
, And the double-wrapped packaging was achieved by further packaging the upper part which had been previously packaged.

[0004]

However, the conventional double-roll packaging as described above is performed in two steps of first wrapping with an inner wrapping material and then wrapping with an outer wrapping material, so that the required packaging time is doubled. In addition, there is a problem that the area required for installation is increased due to the provision of a device for rewinding and feeding the raw material roll on the left and right.

SUMMARY OF THE INVENTION The present invention addresses the above-mentioned situation and reduces the area required for installation of the apparatus by considering the arrangement of the raw material rolls, thereby facilitating the installation of the apparatus and shortening the time required for packaging. It is an object of the present invention to achieve simplification of double-wrap packaging.

[0006]

That is, a feature of the present invention that achieves the above object is that two types of packaging materials are used for inner and outer packaging.
An inner wrapping material roll as an wrapping material feeding device for wrapping the rolls to be wrapped and an inner wrapping material piece feeding mechanism that feeds out the wrapping material from the raw material roll, cuts it to a required length, and sends it out. A packing material raw roll and an outer packing material sending mechanism for feeding the packing material from the material roll, cutting the cut material to a required length, and sending the cut material to a required length; On the other hand, the outer packaging material delivery mechanism is arranged so as to be able to deliver the outer packaging material piece downwardly and to bias the upper inner packaging material piece toward the lower outer packaging piece toward one side in the traveling direction of the transfer conveyor. The packaging material transporting conveyor comprises an upper belt and a lower belt having a length that is longer than the upper belt and having an extending portion at the front, and the outer packaging material delivery mechanism is provided at the front end of the lower belt. While facing the side,
The delivery side of the inner packaging material delivery mechanism is located at the front end of the upper belt so that the inner packaging material piece is superimposed on the upper surface of the outer packaging material piece on the lower belt and transported.

According to a second aspect of the present invention, the above structure is developed to make it more practical. The outer wrapping material is made larger than the inner wrapping material, and the inner wrapping material piece is placed on the upper surface of the outer wrapping material piece. The present invention is characterized in that the inner packaging material pieces are superposed so that there is a margin on both front and rear sides and one side edge side.

The device according to claim 3 is a device for simultaneously applying an adhesive tape for fixing the end of the packaging, wherein the packaging material is unwound from the outer packaging material roll and cut before being cut as an outer packaging material piece. It is characterized in that an adhesive tape is fed out from an adhesive tape roll to one side edge of the outer packaging material piece and is attached thereto.

[0009]

According to the apparatus of the present invention, first, an outer packaging material such as polyethylene laminated kraft paper is unwound from the outer material roll and cut into packaging material pieces having a length corresponding to the width of the roll to be wrapped. Transfer on a belt.

Next, when the above-mentioned wrapping material piece reaches the position where it merges with the upper belt, an inner wrapping material piece such as a foamed polyurethane laminated paper cut out to a required size is fed out from the upper material roll to the position. Then, the outer packaging material pieces, which are transported on the lower belt, are superimposed on the upper surface of the outer packaging material pieces while being biased toward one side in the traveling direction, and the two packaging material pieces are transported while being sandwiched between the upper and lower belts. When it reaches the wrapping position, it stops and is fed toward the roll to be wrapped in a direction orthogonal to the transport direction, and double-wrapping is performed by known means.

The outer packaging piece is made slightly larger than the inner packaging piece, and when both packaging pieces are superimposed, there is a margin on both front and rear sides and one side of the inner packaging piece. Then, the joining portion of the double body-wrapping is shifted, and a wrap margin is formed on both sides in the width direction of the roll to be wrapped, so that the packaging becomes easier and a beautiful package is obtained.

Further, if an adhesive tape is attached to one side of the outer packaging material in advance, the double-wrapped package is also fixed at the same time, and the packaging operation is easy and efficient.
