Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slitter for cutting an object to be processed such as a sticker sheet (tack paper).
More specifically, the present invention relates to a slitter device capable of connecting an object to be processed, such as a seal base paper.

[0002]

2. Description of the Related Art In order to clearly indicate the product name, quality indication, expiration date, etc. on a product or a product packaging container, a sheet of paper such as a seal base paper which can be easily attached to the product or a product packaging container by peeling off one side. Paper or resin products having a layer structure are frequently used. This sticker base paper usually has a thin film-shaped surface layer (sealing material) on the surface of which characters, symbols, and patterns of predetermined contents are printed, and an adhesive applied to the surface layer and applied to the back surface of the surface layer. While protecting,
It is made of a backing material (sometimes referred to as a “separator”) that is easy to peel so that the back surface appears easily, and is finished in a roll shape wound by a predetermined length on a core having a predetermined width. However, there are also cases where the use is finished in a flat sheet shape.

[0003] Generally, a plurality of seals are printed on the roll-shaped seal base paper in the width direction so as to be attached to an adherend, and when used, slitting is performed by a slitter device so as to become individual seal base papers. And
In the next step, the separators are peeled off one by one in a flow operation, and a seal is attached to a product or a packaging container of the product. This sticking operation is performed mechanically and automatically, but there is almost no case where a single roll of sticker base paper is used up without excess or deficiency for sticking to all products. The seal base paper remains. These remaining rolls are stored on warehouse shelves or the like until the next similar operation is required.

[0004]

However, the stock amount of the remaining rolls having different lengths is increasing, and the roll width of the seal base paper is also increased due to the recent variety of the product group. Is not always used frequently, and as a result, the amount of roll-shaped seal base paper to be stored becomes enormous, and there are many cases where it is difficult to secure a storage place. When the storage amount increases, not only does the storage cost increase, but also there is a limit in securing a wide storage place, and as a result, waste is often discarded as waste, which is wasteful.

On the other hand, it is required that various forms be added to the form of the seal base paper itself in accordance with the diversification of the form of use or handling of the product. For example, slitting is performed by slitting the separator portion. Along with (so-called half-cut), there is also a great demand for a seal base paper that makes it easy to peel off the printed film surface from the separator. In the case of such a seal base paper, the separator is cut from the separator side of the seal base paper using a cutter, so the film surface is thinner than the thickness of the separator. And the commercial value is remarkably reduced or cannot be used, and the production yield is low.

Accordingly, an object of the present invention is to make it possible to effectively use the remaining roll-shaped seal base paper and the like, to reduce waste of unnecessary parts as much as possible, and to manufacture various seal base papers and the like. To provide a highly convenient slitting apparatus.

[0007]

The above object is achieved by the invention described in each claim. That is, the characteristic configuration of the slitter apparatus according to the present invention includes a sending device capable of sending out the workpiece, a worktable capable of connecting the different workpieces, and an adhesive material for connecting the different workpieces. An object of the present invention is to provide an adhesive feeding device that can be fed onto a worktable, a cutter device that performs a slitting process after a connection operation, and a winding device that can wind the slitted workpiece.

[0008] According to this configuration, on the workbench provided between the sending device and the winding device, the object to be processed is processed using the adhesive such as the adhesive tape wound from the adhesive feeding device. Since the connection work becomes possible, the connection work between the workpieces having different widths etc. becomes easy, and not only the workability is remarkably improved, but also the handling which may increase the stock amount or may be discarded. Difficult, non-standard-sized objects having different widths and lengths can be efficiently and long-handed. In addition, when the object to be processed is a seal base paper, the sheet and the separator are once peeled off when the sheet is sent out from the feeder, and only the separator is slitted. By winding, it is possible to produce a half-cut product in which the thin seal is completely free of scratches and cuts.

As a result, it is possible to effectively utilize the remaining roll-shaped seal base paper and the like, and to discard wasteful portions as much as possible, and to manufacture various seal base papers such as half cuts. As a result, a highly convenient slitter device can be provided.

A holding device is provided for fixing the different workpieces on the work table, and the holding device is mounted near the upper surface of the work table so as to be rotatable around one end thereof. Is preferred.

According to this configuration, when connecting the workpieces on the worktable, the workpieces do not move, so that the connection work is easy and the operator can easily handle the holding device. Therefore, the connection workability is high, which is convenient.

The holding device comprises a plurality of holding plates. At least one of the holding plates is capable of holding and fixing the object to be processed, and has a long hole extending over the entire width of the worktable. It is preferred that

According to this configuration, since two different types of objects to be processed can be individually fixed, the vicinity of the end of each of the objects to be processed is partially overlapped, and the length formed on one of the holding plates is reduced. By cutting each object to be processed in the width direction through the holes, opposing portions can be formed, and thereafter, both objects to be processed can be easily connected using an adhesive tape or the like.

In this case, it is more preferable that the elongated hole is formed in a direction slightly inclined from a direction perpendicular to the traveling direction of the workpiece. This is because the opposing portion becomes longer, the connecting portion becomes longer, and the connection strength of the connecting portion can be increased. Of course, in order to lengthen the connection point, a long hole that can be formed into a complicated cut shape with irregularities may be formed in the holding plate, but the cut point is as straight as possible for the sake of performing the connection work using an adhesive tape or the like. It is preferably formed in a shape.

The object to be processed is a two-layered seal base paper composed of a seal material and a backing material, and further includes a peeling and sending mechanism for peeling and sending the object to be processed before slitting. It is preferable to have a winding mechanism for slitting only the backing material out of the two-layered seal base paper, and then superimposing the two again to form a two-layered seal base paper and winding it up.

According to this configuration, of the two-layer seal base paper, only the backing material is slit and cut, and the seal is attached again, so that the thin seal may be damaged, The occurrence of a cutting point is completely eliminated. Therefore, the productivity of half-cut products, which have conventionally caused a large number of defective products, which has significantly reduced the commercial value and reduced the yield, can be significantly improved.

[0017] It is preferable that a sticking mechanism capable of sticking another film layer is provided on one surface of the sealing material peeled and fed by the peeling / sending mechanism.

According to this configuration, another film layer can be adhered to the back surface of the sealed article coated with the adhesive,
The location of the adhesive can be limited, and the heat shrinkage of the adhesive applied to the back of the seal can be reduced as much as possible in the heating process such as the molding process after the seal is attached, and the surface can be wrinkled. This makes it difficult to enter the market, and the product value can be maintained high.

[0019]

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a front structure of the slitter device according to the present embodiment, and FIG. 2 shows a planar structure.
The slitter device 1 includes an unwinding roll 2 as a delivery device and a winding roll 3 as a winding device, and a seal base paper, which is a kind of a processing object having a different width wound around these rolls. After connecting the table 4 as a work table for connecting P and P 'and the sticker base paper P and P',

The seal base paper P wound on the unwinding roll 2 passes through the first tension roller 7 and the pressing roller 8, and is rotatable around the support roller 9, the second tension roller 10, and the support shaft 10a. It is configured to be wound around a take-up roll 3 via a roller device 11. It should be noted that FIG. 13 shows a holding roller 8, a supporting roller 9, a second tension roller 10, and an adjusting roller device 1.
No. 1 is a support cover body for supporting one end.
Is a housing that surrounds the motor M and a transmission mechanism that transmits the power of the motor M, and that cantileverly supports the unwind roll 2 and the take-up roll 3. The slitter device 1 has a caster 15 attached to the lower portion, and is easy to move.

Of course, the slitter 1 can also be used as a normal slitter, in which case,
Simply pull out the seal base paper P from the unwinding roll 2,
It can be wound by the winding roll 3 while slitting to a predetermined width by the cutter device 5.

When slitting is performed by connecting sticker sheets P and P 'having different widths, a pressing device 6 described later is used. That is, since the seal base paper P wound around the unwinding roll 2 and the seal base paper P ′ wound around the take-up roll 3 are connected on the table 4, the pressing device 6 and the two seal base papers P, An adhesive tape feeding device 12 for connection, which is an adhesive feeding device for connecting P ′, is attached above the table 4 respectively. Although not shown, the adhesive tape feeding device 12 is configured by winding a long adhesive tape around an axis, and a predetermined length of the adhesive tape can be pulled out from one end of the adhesive tape to the table 4 side. ing.

The holding device 6 is made up of holding plates 6a, 6b, 6c made of three thin and elongated iron plates, and one end on the short side is provided with a hinge 6e provided on the upper surface of the table 4. As a rotation axis, it is rotatable upward. FIG. 2 shows a state in which the holding plates 6a, 6b, 6c lie down on the table 4, and FIG. 1 shows a state in which the other end is opened upward by about 90 ° around the hinge 6e.

Of the pressing plates 6a, 6b, 6c, the pressing plates 6a, 6 located on the entrance side and the exit side in the traveling direction of the seal base paper.
A magnet is attached to the back surface of c, and when these press plates 6a and 6c fall down to fix the seal base paper on the table 4, it can be firmly sandwiched and fixed between the table and the iron table 4. The central holding plate 6b is formed with a long hole 6d penetrating in a direction crossing the entire width of the table in a direction slightly inclined from a direction perpendicular to the running direction of the seal base paper, and the seal base papers P and P '. Can be cut by inserting a cutter knife or the like into the elongated hole and moving it.

Next, a method of connecting and slitting sticker papers having different widths using the slitter apparatus 1 will be described. A wide roll base paper P is wound around the unwind roll 2, and a narrow roll base paper P ′ is wound around the take-up roll 3. Both roll base papers P,
Pull out each end of P 'onto table 4. And
For example, the end of the wide roll base paper P is first drawn out onto the table 4. The end portions of the rolled base paper P pulled out are rotated by pressing the holding plates 6a and 6b which are arranged in advance in the open position.
Lie down and fix. Next, the end portion of the roll base paper P ′ is disposed on the roll base paper P fixed on the table 4 so as to overlap at least at the position of the holding plate 6b where the long hole 6d is formed. The roll base papers P and P 'are cut at the position where the long holes are formed by using a cutter knife or the like at the overlapping portion of the two roll base papers P and P'. Pressing plates 6a, 6
When b and 6c are opened and the cut margin is removed, the two roll base papers P and P 'are opposed to each other with their ends in contact with each other.

While maintaining the state in which the end of one roll base paper is clamped and fixed by any of the press plates 6a, 6b, 6c, the press plate fixing the end of the other roll base paper is opened, and the roll is released. A part of the base paper is turned upside down, and the adhesive tape wound around the adhesive tape device for connection 12 is pulled out and arranged below it. In this case, the adhesive tape is arranged such that the end of the other roll base paper is adhered to a substantially central position in the width direction of the adhesive tape. Then, an adhesive tape is stuck on the back side of the roll base paper by returning the end of the other roll base paper to its original position, and the same manner is applied to a half part in the width direction of the unbonded adhesive tape. If the ends of one of the roll base papers are once inverted and then returned to the original state, the ends of the two roll base papers P and P 'are opposed to each other and are closely connected. Further, the adhesive tape is re-applied from above the positions facing the ends of the two roll base papers P and P ', and the excess adhesive tape portion at the end positions is cut and removed with a cutter knife or the like to complete the connection operation. I do.

The two base paper sheets connected to each other are slit into a predetermined width by a cutter device 5 while being wound up by a winding roll 3.
Is wound up. In this way, a part of the wide roll base paper is cut and removed, but a long roll base paper that matches the narrow roll base paper is generated, and the removed portion is minimized. It is possible to change the surplus roll base paper which may only be discarded eventually to a high-value roll base paper that can be reused, by simply increasing the stock amount.

[Another Embodiment] (1) FIG. 3 shows a slitter apparatus 100 capable of easily forming a half-cut product without causing a cutting trouble.
The front structure of is shown. In the slitter device 100 shown in FIG. 3, members having the same functions as those of the slitter device 1 of the above embodiment are given the same reference numerals.

This slitting apparatus 100 includes a table 4
The roller group 16a, 16b that guides only the seal material S out of the seal base paper is provided at a position below the seal base paper, the seal material S and the separator are separated from the seal base paper, and the separator portion is slit by the cutter device 5. At the same time, the separator which has completed the slitting and the sealing material S which has been separately advanced without passing through the cutter device 5 are bonded again and wound around the winding device 3. That is, the seal base paper P is mounted on the unwinding roll 2 in a direction opposite to that of the above-described embodiment, and the separator and the seal S are peeled off at the inner roller 16a of the roller group, and the separator is separated from the first tension roller. 7 and at the same time, the seal object S is sent to a roller 16b arranged opposite to the adjustment roller 11. The separator passes through the pressing roller 8, is cut at a predetermined location by the cutter device 5, and is sent to the second tension roller 10 and the adjusting roller 11. Here, the sealing object S and the slitted separator are again superimposed and wound by the winding roll 3. Here, among the roller groups 16a and 16b,
The roller 16a constitutes a separation sending mechanism.

In this manner, unlike the case of manufacturing a conventional half-cut product, there is no possibility that the thin seal is scratched or cut. Therefore, according to the present embodiment, the productivity of a half-cut product, which conventionally has a relatively high probability of occurrence of defective products and significantly lowers the commercial value and lowers the yield, can be significantly improved. Good.

(2) When the sealing material is stuck to a predetermined article, the adhesive is applied to the entire back surface, so that if a heating process such as a molding process is performed thereafter, heat shrinkage may occur. There are many cases where the commercial value is significantly impaired, such as wrinkling on the surface of the seal. For this reason, it may be desirable to limit the applied portion as much as possible while maintaining the adhesive function of the adhesive. In such an application, FIG.
It is preferable to use an apparatus as shown in FIG.

That is, the slitter device 100 shown in the above (1) is further provided with a feeding roll 17 around which the film F is wound, and the sealing material S is conveyed through several tension rollers while the sealing material S is being conveyed. The film F is attached to the pressure-sensitive adhesive applied surface of the product S. In this case, by setting the width of the film F to be slightly smaller than the width of the sealing material S, the film F can be stuck while leaving a part of the pressure-sensitive adhesive applied surface of the sealing material S. Without impairing the adhesion between S and the separator, the commercial value can be prevented from deteriorating even in a heat process. Here, the feeding roll 17 and the roller attached thereto constitute a mechanism for attaching the film layer to the sealing object.

(3) In the above embodiment, the holding device capable of temporarily fixing the object to be processed on the work table has been described as an example including three pressing plates. The shape and number of sheets are not particularly limited as long as they can be temporarily fixed. The whole may be composed of a single holding plate, or may be formed of a larger number of holding plates.

(4) In the above embodiment, an example was shown in which the base material for sticker was used as the object to be processed. However, the object to be used in the slitter of the present invention is not limited to this, and may differ in width and the like. It can also be used for various paper products, resin products, and composite products obtained by laminating them.
