Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is directed to wrapping a cylindrical packaged object and folding paper, nylon, vinyl, cloth, or any of these materials into the inner periphery of the packaged object. This invention relates to a device for taping sheet-like packaging such as composite materials.

(Prior Art) Conventionally, as a method for wrapping a cylindrical packaged object and folding the edge of a packaging material folded into the inner periphery of the packaged object, for example, Japanese Patent Laid-Open No. 58
The method described in Japanese Patent No. 134825 is known, and it is presumed that the packaging material folded by this method is folded into the inner periphery of the packaged object and taped, but the specific means for doing so is disclosed. There isn't.

The present applicant previously filed a patent application No. 83-63092.
A paper folding device with outer paper attached was proposed.

In this Japanese Patent Application No. Sho [i3-83092], a coil covered with inner wrapping paper is carried onto a cradle roll R,
As shown in FIG. 5, in the process of supplying the outer wrapping paper R to the coil, it is shaped to match the outer circumferential shape of the coil, and is fed onto the coil while being sucked by a paper feeding device until it reaches the coil C. By adhering the tip of the paper P to the coil with a taping device and rotating the coil C with a cradle roll R, the outer wrapping paper P formed into an inverted U shape is wound around the coil.

At this time, due to the difference between the inner circumferential speed and outer circumferential speed of the coil C, paper folds Po occur on the side surface of the coil C. In this state, the coil C is sent to an inner circumferential folding device, and in this inner circumferential folding device, the folds of the outer wrapping paper P formed on the center side of the coil side portion are gradually It is designed to be folded into the inner circumference.

(Problems to be Solved by the Invention) The present invention aims to fold the packaging material, which has been folded at the sides of the packaged object as described above and further folded into the inner periphery of the packaged object (coil), into the packaged object. This paper proposes a taping device for securely attaching the device to the circumference.

(Means for Solving the Problems) The present invention provides a taping device for a packaging material which is folded at the end face of a cylindrical object and folded into the inner periphery. A support is provided on the side of the object to be packaged, and the tape coiler is provided on this support, and a pinch roller and a driven roller are provided below the support to feed the tape. A mechanism is formed, and a cutter is provided in succession after the tape feeding mechanism, and the tape fed from the tape feeding mechanism is sucked and held along the tape conveying path, and is folded into the inner periphery of the packaged object. This is an inner periphery taping device for packaging materials, which is provided with a presser roller that can be moved up and down and is movable up and down, and which is attached to the edge folded portion of the wrapped packaging material and the inner periphery packaging material.

Embodiments of the present invention will be described based on FIGS. 1 to 4.

In FIG. 1, R is a cradle roll, and on this cradle roll R, a coil C whose outer periphery is wrapped with outer wrapping paper P is carried in and placed.

Inner periphery taping devices 1 and 1o for outer periphery wrapping paper P are disposed on both end sides of this cradle roll R, respectively.

A support body 2 is attached to the cono taping apparatuses 1 and 1o and is movable back and forth with respect to a coil C on a cradle roll R by a drive device MO, and a tape supplying and pasting section is configured on this support body 2. That is, this support body 2 is provided with a tape coiler 3 and a rolled tape 4 is attached thereto.

Further, a tape guide roller 5 is installed below the position where the tape 4 is pulled out from the tape coiler 3, and a pinch roller 6 equipped with a drive motor M for pulling out the tape 4 is installed below the tape guide roller 5, and a pinch roller 6 is installed opposite to this. A tape feeding mechanism consisting of a driven roller 7 is provided.

For example, protrusions are formed on the surface of the driven roller 7 to prevent the adhesive surface of the tape 4 from adhering.

Below this feeding mechanism, there is a folded edge portion P of the outer wrapping paper folded around the inner periphery of the coil C, which attracts and holds the tape 4 fed out from the feeding mechanism. A presser roll 8 equipped with a drive motor M2 is disposed to contact and adhere to the inner wrapping paper P1.

This presser roll 8 has a large number of suction ports 8° on its surface to which suction force is applied by the suction device V, is rotatable, and can be raised and lowered and its position adjusted in the circumferential direction of the coil C.

That is, this presser roll 8 has one end supported by the support 2 via a piston rod 1O operated by an air cylinder 9 and a pin 11, and an intermediate portion supported by the support as shown in FIG. It is attached to the other end side of a support arm 14 which is supported via a piston wood 13 operated by an air cylinder 12 and is movable up and down and whose position can be adjusted within a rotation locus about a pin 11 .

Further, this support arm is provided with a guide 8 for guiding the tape 4 from the feeding mechanism to the presser roll 8. A tape cutter 17 attached to a piston rod 16 operated by a cylinder 15 is disposed on the tape 4 conveyance path connecting the feed mechanism and the presser roll 8.

Next, the operation of the wrapping paper inner periphery taping apparatus of the present invention will be explained.

After attaching the inner wrapping paper P1 with the inner wrapping paper attaching device, the outer wrapping paper P1 was wrapped with the outer wrapping paper attaching edge folding device, and the edge folded portion of the outer circumferential paper was folded into the inner circumference. Coil C,
As shown in FIG. 1, the drive device M is carried in and placed on the cradle roll R, and in this state. is operated to move the support 2 of the wrapping paper inner circumference taping device 1゜1 (hereinafter, only 10 will be explained for convenience) in the direction of the coil C, and as shown in FIGS. The supply and adhesion device section is stopped at a predetermined position within the inner periphery of the coil C, and at the same time, the cradle roll is rotated to rotate the coil C.

The tip of the rolled tape 4 mounted on the tape coiler 3 has passed through the guide roller 5 and reached the pinch roller 6 in advance. From this state, the drive motor Ml operates the pinch roller 6, and the pinch roller
The leading end of the tape is drawn between the roller 7 and the driven roller 7, and fed through the guide 18 to the presser roll.

At this time, the suction device v of the presser roll 8 is activated to suction the tape 4 through the suction port 80 of the presser roll 8, and at the same time the presser roll 8 is rotated by the drive motor M2, and the air cylinder 9 is activated. Operates and presser roll 8
, and move this presser roll 8 along the imaginary line (
As shown by the two-dot chain line), the coil C is brought into contact with the inner peripheral surface of the rotating coil C, and this state is maintained until the coil rotates one or two times.

That is, the edge folded portion Po of the outer wrapping paper P folded into the inner periphery of the coil C is sequentially fed into the presser roll 8 by the rotation of the coil C, and as shown by the imaginary line (two-dot chain line) in FIG. As shown in FIG. 4, the tape is stuck and fixed to the inner wrapping paper P attached to the inner circumferential surface of the coil, as shown in FIG.

During this time, when the tape 4 reaches a preset length, it is cut by the cutter 17 operated by the cylinder 15, and the operation of the pinch roller 6 is stopped.

Then, the coil made one rotation to finish pasting and fixing the edge folded part to the inner wrapping paper using the tape, and then made one more rotation to finish, and then the presser roll stopped rotating and was pulled up at the same time. Afterwards, the support is moved back and the taped coil is sent to the next process.

By repeating such operations, the outer wrapping paper folded on the inner periphery is pasted and fixed to the inner wrapping paper for the required number of inner wrapped and outer wrapped coils.

Note that since taping is usually performed at two locations as shown in Figure 4, the taping devices are installed opposite each other across the coil C placed on the cradle roll R as shown in Figure 1, and are usually synchronized. However, since these taping devices operate in almost the same way, one taping device will be explained here for the sake of convenience, and a description of the other taping device will be omitted.

The number of taping locations may be one, and in that case, the taping device may operate one of the locations.

Further, in this taping device, it is preferable that the movement of the rotary support 2 of the coil C, the rotation of the pinch roller 6, the rotation of the presser roll 8, the raising and lowering, and the operation of the cutter are performed synchronously, but they may be changed as necessary. Manual elements such as button operations may be added.

Furthermore, each of these mechanisms, drive mechanisms, etc. are not limited to those in this embodiment, but may be selected as appropriate.

(Effects of the Invention) As explained above, since the device of the present invention is composed of a pinch roller, a driven roller, a presser roll, a cutter, and a guide, the following effects can be obtained.

(+) By using the present invention in a device that folds the edge of the packaging material while rotating the coil, it is possible to perform the taping at the same time as folding the edge, thereby further shortening the cycle time of coil packaging.

(2) Since the tape is taped while being pulled out, there is no need to measure the tape length etc. in advance.

Additionally, unnecessary mechanical controls are reduced, making the device simple. Furthermore, equipment costs can be reduced.

(3) Since the entire inner circumference of the coil is taped, it is easy to reliably isolate the coil from the outside air.
It is also easy to suppress quality deterioration such as oxidation of the coil.
