Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-layered structure formed by sticking on an adhesive surface, for example, a long band-shaped material such as a label material or a sealing material. The present invention relates to a debris peeling device for stripping and processing a strip-shaped residue (hereinafter simply referred to as a band-shaped residue) of a strip (hereinafter, simply referred to as a band-shaped material) in a state punched out by the method.

[0002]

2. Description of the Related Art FIG. 1 is a side view of an example of a conventional delamination apparatus.

The strip 1 conveyed from the left side of FIG. 1 reaches a peeling roller 3 via a guide roller 2, where the strip 1 is peeled off from the strip scrap 4 at the shading portion, and the strip body 1 a is passed through a guide roller 5 a. After being wound around and contacting the outer peripheral surface of the drive roller 7 that is rotationally driven by the drive motor 6 capable of adjusting the speed and preventing slippage, the next process on the right side of the drawing through the guide roller 5b,
For example, it is transported to a winding step or the like.

[0004] The transport speed of the strip 1 is adjusted by the motor 6.
It is indispensable to apply a tension to stably transport the paper. Referring to FIG. 1, an example of this tension application will be described. The rotation of the shaft body is adjusted by a powder brake 9 or the like, and by this adjustment, the tension of the band from the brake roller shaft 8 to the drive roller 7 is appropriately maintained, and the band residue 4 is formed. It is to be stably peeled.

After the strip-shaped waste 4 is peeled off by the peeling roller 3 provided in the vicinity where the tension in the belt state 1 is stable, for example, the wind-up winding mounted on the wind-up winding shaft 11 driven by the torque motor 10 The paper is wound around the paper tube 12 to form a roll-shaped bandage 13 (hereinafter, simply referred to as a ground roll).

[0006] From the problem of strength, it is not permissible to apply a strong tension to the strip-shaped debris 4 to be stably wound as in a general roll. Therefore, conventionally, for example, as in this example,
The structure is such that excessive winding driving tension is not generated in the band-shaped debris 4 after peeling, for example, the debris is wound by the torque motor 10 that stops when a load exceeding the set torque is applied.

[0007]

As shown in FIG. 2, the strip-shaped debris 4 which has been peeled off generally has a hole 4x structure in large part, and has a thin frame 4y (hereinafter simply referred to as a vertical bar) and a horizontal bar 4z. Are connected. Conventionally, the scrap winding shaft 11 is installed in parallel with the roller group such as the guide roller 2 and the drive roller 7 which support the strip 1, so that when stripping, only the tension in the direction of the arrow on the strip scrap 4, that is, the vertical bar 4 y is applied. Since the tension for peeling cannot be given and the horizontal rail 4z only peels off due to the indirect force affected by the tension of the vertical rail 4y, the vertical rail
The separation of the central part of the horizontal rail 4z, which has the least effect of the tension of 4y, is delayed, and it is impossible to peel the horizontal rail 4z uniformly at the same time.

[0008] The actual delamination is performed through a fixed object such as a peeling roller 3 or a release plate for the purpose of assisting the delamination as shown in FIG. 3. In particular, when the width of the vertical rail 4y is narrow and the width of the horizontal rail 4z is wide, the delamination of the horizontal rail 4z causes a twist to be generated, and the stress is concentrated on the portion A to easily cut.

Various efforts have been made to solve this problem. For example, the width of the vertical bar 4y is increased so that the cutting is not easily performed, and for example, a strip made of a fibrous material is used.
However, it is used only for a limited number of applications because of the large cost and labor. Therefore, the debris must be peeled off at such a speed that the debris is not cut, so the efficiency of the whole process is not improved. At present, strip-shaped waste 4 is removed, and a large amount of labor is required for the removal of the waste and the treatment of the large bulk after the removal.

Further, in the conventional peeling method, as shown in FIG. 4, there is a great possibility that the product 14 indicated by the hatched portion will be lifted up by the band-like waste 4 depending on the shape of the waste and the state of punching. In order to solve this problem, attempts have been made to make the peeling angle B acute, or to devise the shape of the peeling part of the peeling roller 3. In other words, the problem of so-called product rise and the problem of cutting off are contradictory, and have not yet reached a fundamental solution.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is limited under the condition that the debris is easily cut at the time of peeling or that the product is lifted up with the debris. Because the most inefficient debris stripping process in a series of operations can be dramatically accelerated, and it is impossible to peel off debris due to debris cutting and product rising problems with a conventional debris removal device The purpose is to provide a low-cost and stable swarf removing device that can remove swarf that has been removed by hand and contribute to significant productivity improvement. And Furthermore, the stabilization of the debris makes it unnecessary to reinforce the debris, so that it is intended to contribute to the saving of raw material resources and the reduction in the size of the debris.

[0012]

The present invention employs the following means in order to achieve the above object. That is, the figure
As shown in FIG. 5, the strip 1 advances in a direction always perpendicular to the axis of the group of guide rollers 15 parallel to each other that supports the advance, but the strip-shaped residue 4 after peeling is aligned with the axis of the group of guide rollers 15. When it is advanced at a non-perpendicular angle, for example, in a direction parallel to the axis of the group of guide rollers 15 and peels off obliquely with respect to the traveling direction of the belt-like body 1, the horizontal rail 4z peels off the vertical rail 4y with little delay As a result, the possibility of cutting is greatly reduced, and the sharpness of the peeling angle can solve the problem of product rise at the same time.

[0013]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 6 is a top view of a peeling section using a peeling member of the debris peeling apparatus of the present invention. FIG. 7 is a perspective view thereof. The description of the common portions such as the belt-shaped body transport portion before and after the delamination is omitted.

A peeling member 16 is used to stabilize the peeled portion and peel off obliquely while applying an appropriate tension to the band-shaped waste 4. Assuming that the axial direction of the guide roller group of the belt-like body 1 installed in parallel with each other is the reference L1, the belt state 1 always advances in the direction L2 perpendicular to L1. In order to separate the band-shaped residue 4 at an angle that is not parallel to the reference L1 between the guide rollers in which the tension of the strip 1 is stable, for example, as the reference L3 is inclined at an angle C with respect to the reference L1, FIG. 1 shows the peeling member 16
In place of the normal peeling roller 3 in the above. That is, the normal peeling roller 3 has a band-like scum at an angle C of zero degree.
4 is peeled off, whereas the peeling member 16 is used in the present invention.
It is characterized in that it is peeled obliquely at an angle.

In this embodiment, the stripping member 16 has a linear axis shape as shown in the figure, but is not limited to this shape. For example, the stripping member 16 is peeled through a conical cone 17 shown in FIG. When making it to be the center axis reference of the conical cone 17
Even if L4 is set in parallel with the reference L1, it is included in the peeling member 16 according to the present invention because it is peeled off diagonally.

It is ideal that the surface of the peeling member 16 has zero friction. However, in practice, since friction always exists, low friction processing such as fluororesin processing is performed, or a rotating roller structure is used. Can be reduced, and the present invention is not limited to the fixed type.

For an application example in which the strip-shaped waste 4 is conveyed along the reference after the peeling, and finally wound up, etc., the guide roller 18 for the scum which determines the transport reference direction L5 installed after the peeling member 16 Must always be input at a right angle to the axis reference L6. Guide roller 18 for scraping swarf 4
In order that the transport reference direction L5 is fixed by always inputting at a right angle to the axis reference L6, the stripping member 16 must be in uniform contact with the entire width of the strip 1 at the time of peeling, and the strip 1 It is installed so as not to be twisted, that is, installed so as not to hinder the progress of the strip 1, and a straight line is formed at a place where the circumference of the peeling member 16 with respect to the axis reference L3 is in contact with the strip 1. The condition is that it is uniform like a shaft shape.

The axis reference L6 of the shading guide roller 18 is set at a position where the angles of the reference L6 and the reference L1 with respect to the reference L3 of the peeling member 16 are equal, that is, the angle C in FIGS. If it is necessary to further install the guide roller 18 for shaving, it is parallel to the axis reference L6, and the strip-shaped chip 4 is perpendicular to the axis reference L6 of the shaving guide roller 18 after the stripping member 16 is peeled off. Is transported along the proper traveling direction reference L5. In other words, the sheet is conveyed in a direction in which it advances and enters at a right angle to the guide roller shaft installed after the peeling member 16. When the adhesive surface of the band-shaped residue 4 comes into contact with the residue guide roller 18, it is necessary in actual operation to apply a fluorine resin process or a knurling process for preventing the surface of the roller from sticking.

In the present embodiment, the stripping member 16 is installed so that the angle C becomes 45 degrees in order to separate the band-shaped chip 4 at an oblique angle of 45 degrees with respect to the strip state 1. Guide roller 18 for moving in the direction perpendicular to
However, the peeling angle is not limited to 45 degrees as long as there is a certain effect for diagonally peeling the band-shaped residue 4.

FIG. 9 is a diagram of a scrap winding device using the peeling member 16 of the present invention. The transport of the strip-like waste 4 after peeling is interlocked with the belt-like state 1, and since it must always maintain a certain level of appropriate tension, the belt-like waste roller 4 is tuned to the transport state of the belt-like state 1 so that the belt-like waste 4 is stable. Is transported. It is easiest to always tune the shaft of the feed roller 19 mechanically with the drive system that transports the belt state 1 to always synchronize with the transport state of the belt-like body 1, but further fine-tune the tension of the belt-like grounds 4 When it is necessary to use the feed motor 20 that is independent of the drive system that transports the band 1, finely adjust the rotation speed of the feed roller 19 to the transport speed in the belt state 1. By doing so, the tension can be adjusted. Alternatively, there is a method in which the tension is adjusted by a device such as a torque motor that stops when a load exceeding the set torque is applied to the scrap feed motor 20. The scrap feed roller 19 is for keeping the strip-shaped chip 4 after peeling and maintaining a certain degree of tension at all times, and the driving method is not particularly limited, and may be installed immediately after peeling.

In order to finally make the band-shaped waste 4 compact, it is wound around a waste paper tube 23 mounted on a waste winding shaft 22 driven by a waste winding motor 21 such as a torque motor, and the waste is wound. The roll 24 is formed. In this example, the scrap feed roller 19 and the scrap winding shaft 22 are independent, but they may be shared.For example, in the case where the scrap feed roller 19 is driven and rotated by a torque motor, it may be directly wound as a winding shaft. Can be.

The winding system shown in FIG. 9 is a so-called center shaft winding system in which the shaving winding motor 22 directly drives the shaving winding shaft 22 to form the shaving roll 24. As shown in FIG. The outer peripheral surface of the scum roll 24 is brought into pressure contact with the outer peripheral surface of the
The so-called surface-driven winding system in which the belt-shaped residue is continuously formed into a roll by rotating the 24 freely on its support shaft 25 to rotate it, and in this system, the center shaft winding is used. Dust roll compared to the removal method
Since there is no influence of the change in the winding diameter of 24, the interlocking with the strip 1 can be made more accurate, and the feed roller 19 can be installed on the guide roller immediately after peeling, so that the distance from peeling to winding can be shortened and peeling There is an advantage that the tension of is stable.

The above is an example in which the strip-shaped waste 4 is peeled off by the peeling member 16 and then conveyed along the reference L5 and finally wound up. However, the present invention is provided immediately after the peeling member 16 as shown in FIG. It is also conceivable to apply the present invention to a system in which a stripping tension is generated by suctioning with a blower 26 or the like, and the strip cake 4 is stably stripped by the stripping member 16 and then applied to a crushing device 27.

[0024]

As is clear from the above description, the peeling member 16 is installed so as to be peeled off at an angle with respect to the traveling direction of the belt-like body 1 so that the vertical bar 4y of the band-like waste 4 having the hole structure can be removed. Since the horizontal rails 4z can be peeled evenly with almost no delay, the possibility of cutting that occurs easily with the conventional peeling method is significantly reduced. In addition, since the problem that the product rises as the product is scraped because the peeling can be performed at an acute angle can be solved at the same time, it is possible to produce a product having a shape that cannot be peeled in the past. Therefore, in the past, by limiting the speed to the extent that cutting of the band-shaped debris 4 does not occur in the debris peeling apparatus, the current situation where extremely inefficient production is performed without utilizing the original processing capacity of the entire process, The descaling apparatus according to the present invention can provide, at low cost, a high speed by stabilizing the descaling operation and a great improvement in productivity by a high speed of the belt-like body conveyance accompanying the stabilizing operation.

Further, the present invention also provides a stable and high-speed peeling device for a residue which has been peeled off by a human hand due to a shape which cannot be peeled off by a chip peeling device. It is possible to reduce a great deal of labor and cost because it is possible, and furthermore, if a scraping winding device is added, the scrap after peeling can be made into a compact roll shape,
The size of the large bulk after the peeling by the hand patch, which is conventionally serious, can be remarkably reduced, and the waste disposal can be made easier.

Further, conventionally, the use of the peeling apparatus of the present invention eliminates the need for reinforcement such as increasing the width of the swarf portion or inserting fibers only to prevent swarf cutting. Lower costs, that is to say resource savings can easily be achieved, and the absolute amount of dregs can be further reduced, thus greatly contributing to waste disposal problems.
