Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging material feeding device for body-wrapping a cylindrical object (hereinafter referred to as a packaged roll), and more specifically, it stacks two types of packaging materials having different characteristics. The present invention relates to a packaging material feeding device for body-wrapping.

[0002]

2. Description of the Related Art Conventionally, in the case of roll-wrapping of a packaged roll, an original packaging material roll is rewound in the width direction of the packaged roll, unfolded and cut into a length suitable for the width dimension of the packaged roll. It is formed into a packaging material piece, the packaging material piece is transferred to the center of the width direction of the packaged roll, and then sent out toward the packaged roll in a direction orthogonal to the transfer method, and the packaged roll is wound by a body winding device in the next step. I'm trying to get involved. When more powerful protection of the roll to be wrapped is required, two types of packaging materials having different characteristics, for example, foamed polyurethane laminated paper as the inner packaging material and polyethylene laminated kraft paper as the outer packaging material are used. The packaged rolls are heavily wrapped around the body.

FIG. 4 shows an outline of a conventional apparatus used for such double-wrapping packaging, and a rewinding apparatus for different types of original packaging material rolls 2 and 2'on the left and right with the packaging material developing and conveying conveyor 1 as the center. 3, 3 ', the feeding devices 4, 4', and the cutters 5, 5'are arranged. First, the original packaging material roll 2 used on the inner side of one side is rewound, developed, and cut by the cutter 5. It is sent to the left in the figure, transferred to the widthwise center position (CC) of the roll to be wrapped R, sent out in the direction perpendicular to the arrow toward the roll to be wrapped R, and wrapped in a roll. Then, subsequently, the outer packaging material roll 2'is rewound and unfolded, and similarly cut by a cutter 5'to the packaging material piece on the right side of the drawing, at the center position (C in the width direction of the roll R to be packaged). -C) and roll to be wrapped R at right angles
A double-wrapping package was achieved by sending it to the package and further packing it over the previously wrapped body.

[0004]

However, since the conventional double-wrapping packaging as described above is carried out in two steps of first wrapping with the inner packaging material and then with the outer packaging material, the packaging time is doubled. In addition, since the rewinding and unwinding device of the packaging material roll is arranged on the left and right, there is a problem that the required installation area becomes large.

The present invention copes with the above-mentioned situation, reduces the required area for equipment installation by considering the arrangement of the packaging material original roll, facilitates equipment installation, and shortens the time required for packaging. It is intended to achieve simplification of double-wrapping.

[0006]

That is, the feature of the present invention that achieves the above-mentioned object is that two types of packaging materials are provided inside and outside.
An inner packaging material original roll as a packaging material feeding device for stacking sheets to be wrapped and an inner packaging material piece feeding mechanism for feeding the packaging material from the original fabric roll, cutting it to a required length, and feeding it. An original packaging material roll and an outer packaging material delivery mechanism for feeding and cutting the packaging material from the original fabric roll to a required length, and an inner packaging material delivery mechanism with the packaging material development transfer conveyor as the center. On the other hand, on the other hand, the outer packaging material piece delivery mechanism is arranged on the lower side, and the upper inner packaging material piece is arranged so as to be biased toward the lower outer packaging material piece to one side in the transfer conveyor advancing direction and can be delivered. The packaging material spreading and transporting conveyor is composed of an upper belt and a lower belt that is longer than the upper belt and has an extending portion at the front portion, and the outer packaging material piece feeding mechanism is fed to the front end portion of the lower belt. While facing the side,
The delivery side of the inner packaging material delivery mechanism is faced to the front end of the upper belt, and the inner packaging material piece is superposed and transferred on the upper surface of the outer packaging material piece on the lower belt.

A device according to claim 2 is a device in which the above structure is developed to make it more practical. The outer wrapping material is larger than the inner wrapping material, and the inner wrapping material piece is on the upper surface of the outer wrapping material piece. The inner packaging material piece is characterized in that the inner packaging material is superposed on both front and rear sides and one side edge so that there is a margin.

According to a third aspect of the present invention, an apparatus for simultaneously adhering an adhesive tape for fixing the end of the package is provided, and before the packaging material is fed from the outer packaging material roll and cut into outer packaging material pieces. It is characterized in that an adhesive tape is fed from a pressure-sensitive adhesive tape roll and attached to one side edge of the outer packaging material piece.

[0009]

According to the apparatus of the present invention, first, the outer packaging material such as polyethylene laminated kraft paper is fed from the outer material roll and cut into packaging material pieces having a length corresponding to the width dimension of the packaged roll, Place on a belt and transfer.

Next, when the wrapping material piece reaches the position where it joins the upper belt, the inner wrapping material piece such as foamed polyurethane laminate paper cut out to the required size is fed out from the upper raw roll and is fed to that position. Then, the outer packaging material pieces placed on the lower belt are superposed on the upper surface of the outer packaging material piece while being biased to one side in the traveling direction, and the two packaging material pieces are transferred while being sandwiched between the upper and lower belts. When it reaches the wrapping position, it stops and is sent out toward the packaged roll in the direction orthogonal to the transfer direction, and the double wrapped packaging is performed by the known means.

It should be noted that the outer wrapping material piece is made larger than the inner wrapping material piece, and when both the wrapping material pieces are polymerized, a margin portion is provided on both front and rear sides and one side of the inner wrapping material piece. Then, the joint portion of the double body packaging is displaced and the wrap margins are formed on both sides in the width direction of the packaged roll, so that the packaging becomes easier and a beautiful package is obtained.

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

In this case, the outer wrapping material and the inner wrapping material which are wound on each of the material rolls are usually the cutters 5 and 5 ', and the inner wrapping material has such a length that fits the width dimension of the roll R to be wrapped. On the other hand, while the outer packaging material is cut into the packaging material pieces 2a, the outer packaging material is cut as a packaging material piece 2a 'having a width dimension in which appropriate margin portions 6a and 6b are added to both ends of the width of the roll R to be wrapped as a folding margin. . At this time, needless to say, when the outer material roll is made wider than the inner material roll from the beginning, the margin portion 6c is also formed as a lapping margin on one side edge side of the inner packaging material piece 2a. However, it is not absolutely necessary for the outer wrapping material to be particularly wide.

In the figure, numeral 7 is an adhesive tape roll, which is provided on the way of feeding the packaging material from the outer packaging material original roll 2 ', appropriately feeding it and feeding it to the feeding device 4'. It is arranged so that the tape 8 is drawn out and the adhesive tape 8 is fixed to one side edge of the outer packaging material.

In the apparatus of the present invention, however, in the apparatus of the present invention, the packaging material developing / conveying conveyor 1 is composed of the upper belt 1a and the lower belt 1b which rotate in opposite directions, and the upper and lower belts 1a. , 1b, the lower belt 1b is longer than the upper belt 1a as shown in the drawing, and is formed to have a portion extending in the front direction from the upper belt 1a, and the outer wrapping material is formed at the front end of the lower belt 1a. The delivery side of the one-side delivery mechanism B is configured such that the outer packaging material piece 2'a, which is cut off, is fixed to one side edge with an adhesive tape and is transferred by the lower belt 1b in cooperation with the auxiliary belt 1c.

At the position where the upper belt 1a starts to cooperate with the lower belt 1b, the delivery side of the inner packaging material piece delivery mechanism A provided above the belt conveyor 1 has the delivery direction in the width direction of the lower belt 1b. The inner wrapping material piece 2a, which is biased toward one side and is placed on the lower belt 1b and transferred, is merged and overlapped with the inner wrapping material piece 2a while being biased toward one side in the traveling direction. , Upper and lower belts 1
It is configured to be sandwiched between a and 1b and transferred as a packaging material piece that is polymerized inside and outside to a packaging position which is the next step.

The wrapping device, that is, the body wrapping device, is located at approximately the middle position of the circulation system path of the packaging material developing and conveying conveyor 1 composed of the upper and lower belts 1a and 1b, with respect to the belt conveying direction.
On the side of the conveyor 1 and at this position, the transfer conveyor 1 is stopped to discharge the polymerized packaging material in a direction orthogonal to the transfer direction, and the known double-wrapping package disposed at that position. The wrapped roll R is wrapped by the device.
