Description

The present invention relates to a method of manufacturing a flexible sheet with cuts that processes a flexible magnetic sheet such as a magnet sheet so that the display piece or the like can be easily cut , and to cut the flexible sheet with cuts. It is related with the manufacturing method of the flexible sheet piece taken out .

Conventionally, as a flexible sheet from which a split piece such as a display piece can be easily taken out, various cuts such as scissors are made by putting a cut called half cut or half cut from the surface of one side. Techniques that can be cut by hand without using a cutting tool are known.
For example, in Patent Document 1, a display surface made of synthetic paper or the like is formed on the surface of a flexible sheet magnet (hereinafter referred to as a magnet sheet), and from the display surface side to the middle of the thickness of the magnet sheet. A configuration for making a grid-like cutting line guide cut is disclosed.
On the other hand, as a matter of course, as shown in Patent Document 2, there is also a technique of using a processing equipment having upper and lower blades and cutting a display piece or the like directly from a flexible sheet with the upper and lower blades. Are known.

Japanese Utility Model Publication No. 3-10473 JP 2007-30097 A

However, in the flexible sheet disclosed in Patent Document 1, the final cutting of the divided pieces such as the display piece is performed so as to tear off the portion below the cut line guide line. Therefore, workability is unfavorable, and the cut end is beautifully finished where the blade enters, but the surface below it is exposed in a stripped state, the appearance is not good, and the dimensions are unstable. Thus, a large number of display pieces made by cutting have the disadvantage that they tend to become irregular when they are arranged.
In addition, when the flexible sheet is cut using the upper and lower blades as in Patent Document 2, the contact between the upper and lower blades does not occur from the viewpoint of ensuring work safety and preventing damage to the equipment. Therefore, there is a disadvantage in that high-precision processing equipment is required in production and inspection management must be sufficiently performed.

Therefore, the present invention can easily cut a split piece such as a display piece, and can form a cut surface neatly, and also has high convenience that processing equipment does not need to have high accuracy. It aims at providing the manufacturing method of the flexible sheet | seat with a notch, and the manufacturing method of a flexible sheet piece .

As a result of examining the above problems, the present invention can be achieved by focusing on utilizing the characteristics of the material rather than simply cutting the material by mechanical action. The blade tip of the upper rotary blade and the lower rotary blade so that a plurality of pairs of upper rotary blades and lower rotary blades are formed with acute angles at positions where the upper and lower surfaces of one flexible magnetic sheet face each other A step of bringing the blade tip into contact with the flexible magnetic sheet, a step of adjusting the vertical dimension of the upper rotary blade and the lower rotary blade to a predetermined position, and a plurality of continuous formed by the upper rotary blade a step of processing the flexible magnetic sheet so that each has a residual portion between the notch cut and successive plurality of formed by the lower rotary blade to a flexible magnetic sheet having the residual portion the containing a step of winding into a roll A notched flexible sheet manufacturing method of.

It should be noted that there are two or more cuts for producing the divided pieces, and it is preferable that the cuts for producing the divided pieces can be bent and cut.
In this case, since the width of the divided piece can be largely cut by the cutting unit for producing the divided piece, the convenience is improved as compared to using a plurality of divided pieces having a constant width.

In addition, a flexible magnetic sheet (hereinafter, mainly referred to as “flexible sheet”) is formed in a roll shape and is rotatably held by a support portion, and a tip portion is drawn out and attached to a winding portion. An incision producing device is interposed in the drawer portion of the flexible sheet, and an upper rotary blade capable of making an incision on the upper surface of the flexible sheet drawer portion and an incision in the lower surface In a state where the vertical dimension of the lower rotary blade capable of being adjusted is adjusted to a predetermined position, the winding portion may wind up the flexible sheet to form the cut for making the split pieces. . According to this configuration, since the cutting edge of the cutting blade is completely separated from the cutting edge of the upper rotating blade and the cutting edge of the lower rotating blade, the accuracy of the horizontal mounting position of each blade is particularly sensitive. Since it is not necessary to use, it is suitable in terms of productivity.

  In addition, you may use the sheet | seat formed in flat form as a flexible sheet, In that case, by carrying out press processing with the Thomson blade etc. on the surface and the back surface of a flexible sheet, A cut may be formed.

  As the flexible sheet used in the present invention, a magnetic sheet that is magnetized in a state where a hard magnetic material fine powder is kneaded into an organic polymer elastomer to form a sheet can be used.

  The flexible sheet may be a ferromagnetic sheet formed by kneading a soft magnetic material fine powder into an organic polymer elastomer to form a sheet.

Further, one surface of the flexible sheet is covered with an adhesive, and the exposed surface of the adhesive is further covered with a release paper. It is preferable to implement with a configuration in which a notch is formed because convenience is improved.
Moreover, the manufacturing method of the flexible sheet piece which concerns on this invention folds and cuts out the flexible sheet | seat with a notch manufactured with the manufacturing method of the flexible sheet | seat with an incision concerning the said invention, and takes out. Is .

  According to the present invention, it is possible to easily cut and take out divided pieces such as display pieces and belt-like pieces simply by bending them.

  In addition, the side surfaces of the display piece and the strip-shaped piece that have been taken out are finely cut by cutting from the upper and lower surfaces toward the center, and the remaining portion between the cuts is cut by the notch effect, so there are few irregularities. There is an advantage that it becomes a cut surface, the appearance is beautiful, and the width dimension between the side surfaces does not vary greatly.

In addition, since the remaining portion is formed between the cuts for producing the divided pieces formed on the upper and lower surfaces of the flexible sheet, the tips of the blades for forming the cuts for producing the divided pieces are in contact with each other. There is no.
Therefore, safety during production can be ensured, and since there is no need to pay special attention to the blade and its mounting accuracy, there is no need for high-precision equipment, so there is an advantage in productivity and cost. Also, it has a secondary effect different from the viewpoint as an article.

  And the flexible sheet | seat with a notch | incision of this invention using said flexible sheet | seat fundamentally corresponds to the up-down direction from the surface and back surface of the flexible sheet | seat before a process, and external force is applied. It is configured to form a cut for making a split piece in a state that secures a remaining portion that will not be cut naturally without giving it, but since the manufacturing method and equipment are also involved, the following is also included This will be described in detail.

FIGS. 1-8 shows the figure and modified example for demonstrating the flexible sheet | seat with a notch of Example 1 of this invention.
Specifically, FIG. 1 is a front view of a schematic diagram illustrating the manufacturing method, FIG. 2 is a plan view of the schematic diagram illustrating the manufacturing method, and FIG. 3 is a diagram illustrating the schematic diagram of the manufacturing method from the side (a ) Is a YZ end view, and (b) is a partially enlarged end view of (a).

The state, (d) shows one split piece state, and FIG. 8 shows (a) an end view and (b) a partially enlarged end view when another rotating blade is used.

  Specifically, the unprocessed flexible sheet 1 that is finished into the cut flexible sheet of Example 1 is wound around a central tube 1a made of paper or the like, as shown in FIG. 4A. It has a thickness of about 1.5 mm, a width of about 100 mm, and a length of about 10 m to 15 m.

  And the processing apparatus 2 of this flexible sheet 1 is represented by the front view of FIG. 1 which is a schematic diagram explaining a manufacturing method, the top view of FIG. 2, and the end view which appears in the side surface direction of FIG. In general, a support portion 3 for rotatably attaching the flexible sheet 1, a winding portion 4 for attaching and winding the tip of the flexible sheet 1, and a notch manufacturing apparatus for making a later-described cut into the flexible sheet 1 5 is comprised.

The notch manufacturing device 5 includes an upper rotating device 6 and a lower rotating device 7 that can move in the vertical direction, and the upper rotating device 6 includes spacers 8a, 8b, 8c, 8d, 8e, and 8f. The upper rotary blades 9a, 9b, 9c, 9d, 9e made of a single-sided round knife are attached.
On the other hand, the lower rotating device 7 is attached with lower rotating blades 11a, 11b, 11c, 11d, 11e made of a single-sided round knife with spacers 10a, 10b, 10c, 10d, 10e, 10f interposed.

  Each upper rotary blade and each lower rotary blade includes a vertical surface 12a of the blade tip 12 of the upper rotary blade and a vertical surface 13a of the blade tip 13 of the lower rotary blade, as shown in the partial enlarged view of FIG. Are arranged to match.

  And the space | interval A between the blade edge | tips of the front-end | tip 12b of the blade edge | tip 12 of an upper rotary blade, and the front-end | tip 13b of the blade edge | tip 13 of a lower rotary blade is in the process of performing the cutting operation | work in the flexible sheet | seat 1 as mentioned later Alternatively, the dimensions are set such that a residual portion that is not naturally cut is formed in a state where the cutting operation is finished and no external force is applied in the shearing direction or the like.

However, since the appropriate size of the remaining portion is affected by the material specifications of the flexible sheet 1 and the temperature during processing, it is necessary to set it appropriately according to those conditions.
In the case of a general-purpose magnet sheet having a thickness of 1.5 mm, a preferable value is about 0.5 mm.

  Thus, since the size of the remaining portion is important, the upper rotary blades 9a, 9b, 9c, 9d, 9e and the lower rotary blades 11a, 11b, 11c, 11d, 11e are basically the same. It is preferable to use one having an outer shape, that is, the same specification product.

However, if both side surfaces of the flexible sheet 1 are uneven in shape or have dirt or the like, both end portions cannot be used as a product, so it is necessary to cut them.
In such a case, the distance A between the cutting edges of the both sides 9a, 9e of the upper rotary blade and both sides 11a, 11e of the lower rotary blade may be made small enough not to contact.
Specifically, only the upper rotary blades 9a and 9e and / or the lower rotary blades 11a and 11e can be handled by using a rotary blade having a large outer shape.

  In addition, the arrangement intervals of the upper rotary blades 9a, 9b, 9c, 9d, and 9e and the lower rotary blades 11a, 11b, 11c, 11d, and 11e may be constant or appropriately changed according to the use. Can be selected and implemented.

  As explained so far, the manufacturing method in the present embodiment is safe because the tip 12b of the blade tip 12 of the upper rotary blade and the tip 13b of the blade tip 13 of the lower rotary blade do not come into contact with each other during the machining operation. Moreover, since uniform quality is ensured, it is suitable for production.

  Under the circumstances as described above, the method for producing the flexible sheet with cuts of Example 1 will now be described in detail.

  First, as a preparation stage, a gap in the vertical direction between the upper rotating device 6 and the lower rotating device 7 in the notch manufacturing device 5 of the processing device 2 is largely opened.

  Next, in a state where the central tube 1a of the flexible sheet 1 is rotatably attached to the support part 3 of the processing apparatus 2, the top end part 1b of the flexible sheet 1 is attached to the above-mentioned cutting production apparatus 5 with an upper rotation device. 6 is attached to a take-up cylinder 1c made of paper or the like, which is rotatably attached to the take-up unit 4 by an appropriate means such as a gum tape (not shown).

From this state, the flexible sheet 1 will be cut, but first, the upper rotation device 6 or the lower rotation device 7 is moved so as to narrow in the vertical direction, The upper rotary blades 9a, 9b, 9c, 9d, and 9e attached to the upper rotary device 6 and the lower rotary blades 11a, 11b, 11c, 11d, and 11e attached to the lower rotary device 7 are used as the flexible sheet 1. 3d, and further, the tip 12b of the blade tip 12 of the upper rotary blade and the tip 13b of the blade tip 13 of the lower rotary blade are bitten as shown in FIG. Adjust until the dimensions are reached.
By this operation, the starting point of the upper surface notch 14 and the lower surface notch 15 is formed in the flexible sheet 1, and between the tip 16 of the upper surface notch 14 and the tip 17 of the lower surface notch 15, A remaining portion 18 is formed.

  Next, as shown in FIG. 1, when the winding unit 4 in the processing device 2 is rotated in the direction of the arrow, the roll-shaped flexible sheet 1 that is rotatably attached to the support unit 3 is pulled out. As it is rotated, it is wound around the winding portion 4 of the processing device 2.

At this time, the lead-out portion 1d of the flexible sheet 1 passes through the incision making device 5, so that the upper rotary blades 9a, 9b, 9c, 9d, 9e and the lower rotary blades 11a, 11b, 11c, 11d , 11e while rotating the upper and lower surfaces by these blades.
Specifically, as shown in FIG. 2, upper cuts 14a, 14b, 14c, 14d, and 14e are formed in this order by the upper rotary blades 9a, 9b, 9c, 9d, and 9e.
Although not shown in FIG. 2, the lower rotary blades 11a, 11b, 11c, 11d, and 11e similarly form the cuts on the lower surface. (See Figure 4 (d) below)

  As described above, the flexible sheet 1 is formed with cuts. The flexible sheet 1 is pulled out and cut not only by the rotational force of the winding unit 4 but also by the upper rotating device. The rotation of 6, the rotation of the lower rotation device 7, and the rotation of the support unit 3 may be used together as being capable of rotating by itself.

When the cutting operation is completed, as shown in FIG. 4B, the flexible sheet 19 with cutting immediately after processing is completed in a roll state.
In addition, on the external surface, cuts 14a, 14b, 14c, 14d, and 14e on the upper surface are formed, and divided pieces 20a, 20b, 20c, 20d, 20e, and 20f are formed by these cuts.

Even in this state, it can be said that the flexible sheet with cuts is completed.
However, the split pieces 20a and 20f at both ends of the roll have a large variation in the width dimension and tend to be contaminated. Therefore, in this explanation, the following processing is added as a reference form of the manufacturing process. The material is treated as the flexible sheet 21 with notches in Example 1.

Specifically, the flexible sheet 21 with notches of Example 1 is divided into pieces 20a and 20f at both ends of the roll-like flexible sheet 19 with cuts immediately after processing, and the winding located at the center thereof. The cylinder 1c is cut off at the same end face, and as shown in FIG. 4 (c), the cuts 14b, 14c, 14d on the upper surface are inserted at predetermined positions, and divided pieces 20b, 20c, 20d, 20e having a predetermined width are formed. It has become.
As shown in FIG. 4D, the lower surface cuts 15b, 15c, and 15c are formed at positions corresponding to the upper surface cuts 14b, 14c, and 14d so that the leading end of the cut flexible sheet 21 is pulled out. 15d is also formed.

Next, the cutting of a plurality of divided pieces formed on the cut flexible sheet 21 will be described.
FIG. 5 is a partially enlarged side view for explaining the cutting of the divided pieces. Before the work (a), the flexible sheet 21 with the cut has a tip 16 of the cut 14 on the upper surface and a cut on the lower surface. It is in the state which the front-end | tip 17 of 15 opposes.
Here, as shown by the arrow in FIG. 5A, when a force is applied to bend around the upper cut 14, the tip 16 of the upper cut 14 and the tip 17 of the lower cut 15 are respectively Is formed at an acute angle, a notch effect is generated in the portion of the remaining portion 18 formed in the meantime, and it can be easily done with a light force at a cut surface 22 with less unevenness as shown in FIG. Can be cut.

As described above, the flexible sheet 21 with notches according to the present invention can be used in the maximum width state where all the divided pieces are connected as shown in FIG. It has the feature that it can be easily cut.
Therefore, it becomes possible to cut out a divided piece having a desired width according to the application.

FIG. 6 shows a state where a relatively long divided piece is cut out. FIG. 6A shows one divided piece 20e , FIG. 6B shows two divided pieces 20d, 20e , and FIG. c) shows the state of cutting out in the state of the width of the three divided pieces 20c, 20d, and 20e. Each piece is cut to a desired length and then used after being cut from a roll.

  On the other hand, when the length to be used has been determined and the width is to be changed in that state, as shown in FIG. 7, using a flexible sheet 23 with a notch of a predetermined length cut from the roll, In addition to the full width state composed of the four divided pieces 23b, 23c, 23d, and 23e in FIG. 7A, for example, the three divided pieces 23c, 23d, and 23e in FIG. Like the two divided pieces 23d and 23e and the one divided piece 23e in FIG. 7D, a desired continuous divided piece or one divided piece can be cut out and used.

As described above, in the flexible sheet with notches in the present invention, a plurality of divided pieces are formed, and can be easily cut out to a desired width with a clean cut.
Therefore, when this flexible sheet with cuts is actually used as a construction member for a wall or the like, only a thin flexible sheet is used, or a plurality of flexible sheets are arranged side by side, or a wide flexible sheet is used. Therefore, the workability is remarkably improved as compared with the work such as cutting and using a knife with a predetermined width.

In addition, although the upper rotary blade and the lower rotary blade used in the manufacturing method for producing a present Example were demonstrated with the single-sided round knife, it is not necessary to restrict to this.
For example, similar to the end view of FIG. 3A and the partially enlarged view of FIG. 3B, the end view of FIG. 8A and the partially enlarged end view of FIG. The upper rotary blades 24a, 24b, 24c, 24d, 24e and the lower rotary blades 25a, 25b, 25c, 25d, 25e use double-sided round knives, and the blade tip 26 of the upper rotary blade and the blade tip of the lower rotary blade The positional relationship of 27 may be arranged similarly.
Thus, if an upper rotary blade and a lower rotary blade have a sharp blade edge | tip, it can select and employ | adopt suitably.

Example 1 demonstrated the method of making it pass between an upper rotary blade and a lower rotary blade roughly using a roll-shaped flexible sheet | seat, in order to cut | inscribe a flexible sheet.
However, it goes without saying that the method of cutting the flexible sheet is not limited to this.

Example 2 shows a configuration in which a flat sheet is used as the flexible sheet, and the cut is made by a press method.
FIG. 9 shows an example of the manufacturing method. First, as shown in the process explanatory diagram of FIG. 9A, a Thomson machine (not shown) is applied to one surface of the flat flexible sheet 31. The Thomson blade 33 embedded in the Thomson die 32 is pressed so as to ensure a predetermined depth.
Then, if the Thomson die 32 is released, a cut 34a is formed on one surface of the flat flexible sheet 31 as shown in FIG. 9B.
Next, if the flat flexible sheet 31 is turned over and the cut 34b is formed at the same position as the cut 34a by forming the cut 34b, the flat flexible sheet 31 is formed as shown in FIG. Cuts 34a and 34b are formed on both surfaces of 31, and the same operational effects as in the first embodiment can be obtained.

  However, in Example 2, it is possible to make a cut in the entire length direction as in the flexible sheet 23 with a cut having a predetermined length shown in FIG. You can also make cuts at various positions.

FIGS. 10A and 10B show two examples. First, FIG. 10A shows a perspective view with a grid-like cut, and more specifically, with respect to a flat flexible sheet 31. Four horizontal cuts 36a, 36b, 36c, 36d and three vertical cuts 36e, 36f, 36g are formed, and six subdivided pieces 37a, 37b, which can be used for display pieces, etc. 37c, 37d, 37e, 37f and an outer frame 37g are formed.
These six subdivided pieces 37a, 37b, 37c, 37d, 37e, 37f and the outer frame 37g can be freely separated as desired. For example, as shown in FIG. The outer frame 37g and the joined body of the six small divided pieces can be separated from each other, and one small divided piece 37c can be further separated from the joined body of the six small divided pieces.

Further, as shown in the perspective view of FIG. 10 (c) in which an arbitrarily-shaped divided piece is cut, the flat flexible sheet 31 has a free shape, for example, a cut 38a having a circular outer shape, a triangle. A shape cut 38b and a square cut 38c are formed.
Then, the circular segment 39a, the triangular segment 39b, and the quadrangular segment 39c formed by the cuts are used separately from the outer frame 39d as shown in FIG. 10 (d). can do.

It should be noted that the present invention can be implemented with various modifications without departing from the spirit of the present invention.
The flexible sheet to be used can be any material as long as the notch can be easily cut, and when a force is applied in the direction of bending with respect to the notch, a notch effect occurs and the sheet can be easily separated. Also good.

  Further, the front and back surfaces of the flexible sheet may be printed or displayed, or another material may be laminated, and the cut may be cut in that state.

FIG. 11 shows an example thereof. Various decorative surface covering materials 42 are attached to the surface of the flexible sheet 41, the adhesive layer 43 is provided on the back surface, and the upper surface is a release paper. The flexible decorative material 45 is configured to be covered with 44.
Then, from the front surface, cuts 46a and 46b on the upper surface reaching the central portion of the flexible sheet 41 through the cover material 42 are made, and from the back surface through the release paper 44 and the adhesive layer 43, When the notches 46c and 46d are inserted, the divided pieces 47a, 47b and 47c are formed.

The flexible sheet with notches according to the present invention can be used by easily separating one flexible sheet into a plurality of pieces.
And it can also be set as the elongate articles | goods which reach several meters, and it can apply also to the articles | goods of the width | variety of several centimeters.
In addition, because the material is made of magnet, it can be attached to ferromagnetic articles such as iron by magnetic adsorption, and if an adhesive layer is provided, it can be attached to many articles other than special materials. Can do.
Therefore, in terms of shape, it can be used in various forms ranging from long width structures and articles such as building walls to small articles such as bulletin board display pieces, and ferromagnetic articles made of magnets. Can be used for mounting, or conversely, when used as a base material for mounting a magnet member made of a ferromagnetic material, the material width can be selected, so that it can be economically superior in proper quality, To a wide range of industrial fields.
