Description

The present invention relates to a notch forming apparatus for a thin film web that forms a notch in the thin film web, and a method for manufacturing a thin film web with a notch.

As a processing method for making it easier to cut a web such as a film, paper, or non-woven fabric by hand along a cutting line or a cutting line such as a pattern, a process called perforation processing for intermittently providing a through hole in the web has been conventionally known. Has been done. However, the web cut out using the perforations has irregularities at the cut end, and the cut out may not be beautiful.

As a processing method for making the cut end of the web cut by hand beautiful, a processing called half-cut processing is known in which a cut is made in a part of the thickness direction of the web so as not to penetrate the web. For example, the half-cut process disclosed in Patent Document 1 is a process in which the print sheet and the pressure-sensitive adhesive layer are cut into a predetermined shape, and the release mount is not completely cut.

Further, the half-cut processing is often used for processing a relatively thick sheet, and in this case, it is often used for a purpose other than making it easy to cut by hand along the cutting line. For example, it may be used to make it easier to bend into a box shape by processing a thick sheet of box material.

Japanese Unexamined Patent Publication No. 2000-254891

Half-cut processing makes it possible to easily cut by hand along the cutting line, but if the cutting depth is not constant, it will be cut off unintentionally or when you try to cut it off. There was a problem that it could not be easily cut.

To prevent these problems, it is necessary to keep the ratio of the depth of cut to the thickness of the web constant. That is, the thinner the thickness, the more accurate the cutting depth is required. For example, in a thin film web having a thickness of less than 100 μm, it is necessary to keep the accuracy of the cutting depth constant in micron units.

In addition, the thin film web is more flexible than the thick sheet and the web itself is easily deformed, and the web is easily shaken up and down (in the direction of the web thickness direction) during cutting, and the depth of cut can be adjusted simply by adjusting the cutter position. There was a problem that it was difficult to maintain high accuracy.

The present invention solves the above-mentioned conventional problems, and provides a notch forming apparatus for a thin film web and a method for manufacturing a thin film web with a notch, which can maintain the cutting depth of the thin film web with high accuracy. The purpose is to provide.

In order to achieve the above object, the thin film web notch forming apparatus of the present invention is a thin film web notch forming apparatus that cuts the transferred thin film web between the receiving material and the cutter, and is the receiving material. The thin film web is applied to the blade portion of the cutter while sliding the thin film web along a part of the outer peripheral surface of the receiving material, provided with an actuator that keeps the separation distance between the cutter and the cutter at a predetermined distance. This is characterized by cutting a part of the thin film web in the thickness direction of the thin film web.

The method for producing a thin film web with a notch of the present invention is a method for producing a thin film web with a notch by cutting the transferred thin film web between a receiving material and a cutter, and is an actuator. While keeping the separation distance between the receiving material and the cutter at a predetermined distance and sliding the thin film web along a part of the outer peripheral surface of the receiving material, the thin film web is attached to the blade portion of the cutter. It is characterized in that a part of the web is cut in the thickness direction of the thin film web by hitting.

According to the thin film web notch forming apparatus and the method for manufacturing a thin film web with a notch of the present invention, this separation distance can be easily adjusted by using an actuator for adjusting the separation distance between the receiving material and the cutter. And it can be kept accurate. Further, by sliding the thin film web along a part of the outer peripheral surface of the receiving material, the position of the thin film web is accurately determined, so that the accuracy of the cutting depth of the cutter is improved and the accuracy is stabilized.

In the notch forming apparatus for the thin film web and the method for producing the thin film web with the notch of the present invention, the following configurations are preferable. The base point of the predetermined distance is the detection information when the outer peripheral surface of the receiving material and the blade portion of the cutter are brought into contact with each other to detect the contact, or between the outer peripheral surface of the receiving material and the blade portion of the cutter. It is preferable to determine based on the detection information when the contact between the spacer having a known thickness and the cutter interposed therein is detected. According to this configuration, since the base point is determined by utilizing an existing object or an object having a known thickness, the base point can be calibrated reliably, in a short time, easily and accurately.

It is preferable that the receiving material is fixed and the cutter is separated from the receiving material by the actuator. According to this configuration, since the receiving material is fixed, the position of the receiving material is stabilized, so that the thin film web is less likely to wrinkle and the frictional state between the receiving material and the thin film web is less likely to change, and the cutter It is advantageous for stabilizing the accuracy of the depth of cut. Further, by fixing the receiving material, when a plurality of thin film webs are simultaneously processed by a plurality of cutters, the cutting depth can be arbitrarily changed by each cutter.

It is preferable that the cutter is provided with a curved blade portion, and the thin film web is continuously applied to a predetermined portion of the curved blade portion while being warped by the receiving material. According to this configuration, it is possible to suppress the shake of the cutting edge as compared with the case of using a cutter with a sharp cutting edge, and since the cutter contacts the thin film web as if stroking it, the friction between the cutter and the thin film web is small. At the same time, the friction caused by friction is reduced, the blade is less likely to be frayed, and the life of the cutter is extended.

It is preferable that the contact state between the thin film web and the receiving material is adjusted by the angle adjusting roll. According to this configuration, the frictional resistance generated between the thin film web and the receiving material can be adjusted while maintaining the distance between the receiving material and the cutter. As a result, the wrinkles of the thin film web are stretched on the receiving material to prevent cutting defects due to the wrinkles, and when a plurality of thin film webs are processed at the same time, the accuracy of the processing intervals of the thin film webs can be improved. Further, the frictional resistance can be optimized according to the state, thickness and material of the thin film web.

The cut thin film web is preferably hand-cut. According to the present invention, as described above, the accuracy of the cutting depth of the cutter is increased and the accuracy is stable. Therefore, it is possible to cut while maintaining the cutting depth required for easy cutting by hand, and the cutting property is hand-cut. A thin film web having the above can be stably obtained.

The effects of the present invention are as described above, and by using an actuator for adjusting the separation distance between the receiving material and the cutter, this separation distance can be easily and accurately maintained. Further, by sliding the thin film web along a part of the outer peripheral surface of the receiving material, the position of the thin film web is accurately determined, so that the accuracy of the cutting depth of the cutter is improved and the accuracy is stabilized.

In one embodiment of the present invention, a schematic configuration diagram of a notch forming device at the end of position control of a cutter. FIG. 5 is a schematic configuration diagram of a cut forming device in a state where a thin film web is attached to the cut forming device from the state of FIG. In one embodiment of the present invention, a schematic configuration diagram of a cut forming device in a state where the cutter is raised to a position where a thin film web can be cut.

The present invention relates to a technique for forming a notch in a thin film web, and the thin film web refers to a flat film such as a film, paper, a non-woven fabric, or a metal thin film. In the present embodiment, forming a notch means cutting a part of the thin film web in the thickness direction of the thin film web. Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a schematic configuration diagram of a thin film web notch forming apparatus 1 according to an embodiment of the present invention. This figure shows a state in which the thin film web 10, which is the object of cutting, is attached. As will be described in detail later, in the thin film web 10, a cut is formed by the cutter 5 while being transferred inside the cut forming device 1 along the longitudinal direction thereof. In the present embodiment, the side to which the thin film web 10 is transferred is referred to as the downstream side, and the opposite side is referred to as the upstream side.

In FIG. 1, in the notch forming apparatus, an angle adjusting roll 2, a receiving roll 3 which is a receiving material, and a guide roll 4 are arranged in order from the upstream side along the longitudinal direction of the thin film web 10. The thin film web 10 is in contact with a part of the surface.

The role of the receiving roll 3 is to prevent the thin film web 10 from being pushed by the cutter 5 and moving when the cutter 5 is applied to the thin film web 10, and the contact portion between the outer peripheral surface of the receiving roll 3 and the thin film web 10. Has the role of causing friction in the thin film web 10 and appropriately applying tension to the thin film web 10 to smooth out wrinkles. In the present embodiment, the thin film web 10 is warped along the outer peripheral surface of the receiving roll 3 which is a cylindrical surface, and the thin film web 10 is warped, and friction is generated between the outer peripheral surface of the receiving roll 3 and the thin film web 10. , The thin film web 10 is slid.

Further, by sliding the thin film web 10 along a part of the outer peripheral surface of the receiving roll 3, the position of the thin film web 10 is accurately determined, so that the accuracy of the cutting depth of the cutter 5 is improved and the accuracy is stable. .. More specifically, the thin film web 10 is supported by the receiving roll 3 to suppress the vertical movement, and the vertical movement is also suppressed by applying an appropriate tension to the thin film web 10 due to the frictional resistance of the receiving roll 3. Therefore, the position of the thin film web 10 is accurately determined.

The receiving roll 3 may be rotated, but when it is rotated, it becomes difficult to slide the thin film web 10 on the receiving roll 3, so that the receiving roll 3 is not rotated in this embodiment. By preventing the receiving roll 3 from rotating, the position of the receiving roll 3 may be slightly due to distortion of the rotating shaft, uneven roundness of the rotating shaft, and shaking or vibration due to insufficient clearance or rigidity of the bearing used for rotation. It is possible to suppress the unevenness of the cutting depth caused by the change.

Here, if the frictional resistance between the thin film web 10 and the receiving roll 3 is too large, an excessive load is applied to the thin film web 10, and this load causes scratches on the surface of the thin film web 10 or physical properties of the thin film web 10. It can affect the value. On the contrary, if this frictional resistance is too small, an appropriate tension is not applied to the thin film web 10, and the thin film web 10 may be wrinkled.

Therefore, it is necessary to adjust the frictional resistance depending on the state of the thin film web 10 to be transferred, but in the present embodiment, by adjusting the arrangement position of the angle adjusting roll 2, the position between the receiving roll 3 and the cutter 5 is adjusted. While maintaining the distance, the frictional resistance generated between the thin film web 10 and the receiving roll 3 can be adjusted.

Further, since the wrinkles of the thin film web 10 can be prevented by providing the angle adjusting roll 2, when the thin film web 10 is run and the thin film web 10 is processed at a plurality of places at the same time, the accuracy of the processing interval of the thin film web 10 is improved. Can be done.

The positional relationship between the receiving roll 3 and the angle adjusting roll 2 may be adjusted by adjusting the arrangement position of the receiving roll 3, but it is preferable to adjust the arrangement position of the angle adjusting roll 2. This is because the positional relationship between the receiving roll 3 and the cutter 5 is required to be accurate in order to make a highly accurate cut, and the positional relationship should not be changed at the time of cutting.

In the configuration of the cut forming device 1 as described above, in order to form a cut in the thin film web 10, the cutter 5 is applied to the web 10 that slides along a part of the outer peripheral surface of the receiving roll 3. At this time, since the cutter 5 hits along the transfer direction of the thin film web 10, a cut is formed along the longitudinal direction of the thin film web 10.

The type and shape of the cutter 5 are not particularly limited, the material is not particularly limited, and the cutter 5 may be made of steel, and cemented carbide, ceramic, or the like is preferable in consideration of the life of the blade portion. The cutter 5 shown in FIG. 1 uses a circular blade having a blade portion along the circumference. The circular blade has an arcuate curved blade portion, and can suppress the shake of the cutting edge due to vibration as compared with a blade having a sharp cutting edge.

Further, when cutting with the curved blade portion, the contact range with the thin film web 10 becomes smaller than that with the linear blade portion, and the cutter 5 contacts the thin film web 10 as if stroking it, so that the friction between the cutter 5 and the thin film web 10 is generated. The size is reduced, and the cutter 5 is less likely to shake due to friction. As a result, the blade portion of the cutter 5 is less likely to be frayed, and the life of the cutter 5 is extended. In particular, in the present embodiment, since the thin film web 10 is slid while being warped by the receiving roll 3, the friction between the cutter 5 and the thin film web 10 is further suppressed, which is advantageous for extending the life of the cutter 5. become.

If the thin film web 10 is brought into contact with a flat surface and the thin film web 10 is applied to the cutter 5 without warping, the middle abdomen of the thin film web 10 is loosened in the middle, and the thin film web 10 does not easily float along the flat surface. As a result, the depth of cut may be uneven. In the present embodiment, since the thin film web 10 is received and warped by the roll 3, the floating of the thin film web 10 is suppressed, the thin film web 10 can be reliably aligned with the outer peripheral surface of the roll 3, and the depth of cut is uneven. Can be prevented.

On the other hand, when a circular blade is used and the circular blade is made rotatable, the circular blade or its shaft has uneven roundness, mounting error on the shaft of the circular blade, and shaking and vibration due to insufficient clearance and rigidity of the bearing used for rotation. Etc. will occur, and these will cause uneven cutting depth. For this reason, it is preferable that the circular blade is not rotated, and it is preferable to keep the thin film web continuously in contact with the fixed position of the curved blade portion.

In FIG. 1, the cutter 5 is connected to the actuator 6. The actuator 6 in FIG. 1 is a feed screw type linear acting actuator, and can be fed back from the actuator main body 7 and the actuator main body 7 which are tubular and have a guide (not shown) inside, and a cutter 5 is attached to the tip thereof. It includes a possible actuator movable part 8 and a stepping motor 9. In this configuration, the position of the cutter 5 attached to the tip of the actuator movable portion 8 is displaced by sending back the actuator movable portion 8 from the actuator main body 7 in response to the rotational operation of the stepping motor 9. As a result, the separation distance between the receiving roll 3 and the cutter 5 can be adjusted. In the example of FIG. 1, a stepping motor 9 is used as a drive source for position control, but the present invention is not limited to this, and any electric motor capable of position control may be used. The feed-back method of the actuator 6 is not limited to the feed screw method, and other methods may be used.

By using the actuator 6 for adjusting the separation distance between the receiving roll 3 and the cutter 5 as in the present embodiment, this separation distance can be easily and accurately maintained. More specifically, in the cut formation of the thin film web 10, it is required that the separation distance between the receiving roll 3 and the cutter 5 is constant in micron units. For that purpose, it is necessary that the cutter 5 operates accurately at the target position and is arranged, and keeps the arrangement as it is. Further, when the separation distance between the receiving roll 3 and the cutter 5 changes slightly due to wear or minute displacement of each part during operation, it is preferable to correct this. It is difficult to manually perform this accurate operation and correction, and by using the actuator 6, the separation distance between the receiving roll 3 and the cutter 5 can be easily and accurately maintained.

The position control of the cutter 5 is not particularly limited, but once the cutter 5 is brought into contact with the outer peripheral surface of the receiving roll 3, the contact is detected to determine the base point, and then the cutter 5 is separated from the receiving roll 3 to separate the cutter 5. It is preferable to control the position so that 5 can be arranged at a position separated from the base point by a target distance. Hereinafter, the position control of the cutter 5 will be specifically described with reference to FIGS. 2 to 5.

FIG. 2 shows a flowchart showing an example of position control including base point calibration of the cutter 5. FIG. 3 shows a schematic configuration diagram of the notch forming device 1 at the start of position control of the cutter 5. FIG. 4 shows a schematic configuration diagram of the cut forming device 1 at the time of base point correction of the cutter 5, and FIG. 5 shows a schematic configuration diagram of the cut forming device 1 at the end of position control of the cutter 5. There is. When the control by the control means 20 (computer) is started in the state where the cutter 5 is separated from the receiving roll 3 as shown in FIG. 3 (step 100 in FIG. 2), the actuator movable portion 8 is sent out from the holder 7. The cutter 5 rises (step 101 in FIG. 2). After this ascent, the cutter 5 comes into contact with the outer peripheral surface of the receiving roll 3 as shown in FIG. 4 (step 102 in FIG. 2).

Although not shown, a metal wire is connected to the receiving roll 3 and the cutter 5 so that the electric resistance between the receiving roll 3 and the cutter 5 can be detected. Contact can be detected. When the contact between the receiving roll 3 and the cutter 5 is detected, the control means 20 stops sending out the actuator movable portion 8 by the actuator 6, corrects the base point (step 103 in FIG. 2), and sets the distance to zero as the base point. Calibrate to. After that, when the operator inputs the target distance (step 104 in FIG. 2), the actuator movable portion 8 returns to the actuator main body 7 and the cutter 5 is lowered (step 105 in FIG. 2), and the cutter 5 is in the target position. The position control of the cutter 5 is stopped (step 106 in FIG. 2).

When moving the cutter 5, if the base point information from where to move is not accurate, it cannot be moved accurately to the target position. On the other hand, manually adjusting and setting the base point requires precise work, and particularly when a plurality of cutters 5 are used, the amount of work becomes enormous. In the present embodiment, as described above, since the calibration of the base point of the cutter 5 is based on the contact position with the existing receiving roll 3, the calibration of the base point can be performed reliably, in a short time, easily and accurately. If the base point is accurately calibrated, when the cutter 5 is received and separated from the roll 3, the separation position of the cutter 5 may be set with reference to the calibrated base point, and the separation position of the cutter 5 may be adjusted and set. It will be reliable, short time, easy and accurate.

In the present embodiment, the cutter 5 is moved to perform the base point calibration, but the receiving roll 3 may be moved to perform the base point calibration. However, if the position of the receiving roll 3 is moved, the frictional state between the thin film web 10 and the receiving roll 3 changes. Therefore, it is preferable not to move the position of the receiving roll 3 as much as possible. More specifically, since the receiving roll 3 is fixed, the position of the receiving roll 3 is stabilized, so that the thin film web 10 is less likely to wrinkle, and the frictional state between the receiving roll 3 and the thin film web 10 changes. It becomes difficult to do so, which is advantageous for stabilizing the accuracy of the cutting depth of the cutter 5.

Further, when a plurality of thin film webs 10 are processed at the same time, it is necessary to individually adjust the distance between the receiving roll 3 and the corresponding cutter 5, but in this case, moving the receiving roll 3 makes the adjustment difficult. Therefore, it is preferable that the position of the receiving roll 3 is not moved as much as possible, and it is preferable that a plurality of cutters 5 correspond to one receiving roll 3. As a result, the cutting depth can be arbitrarily changed for each cutter 5.

Further, FIGS. 3 to 5 are illustrations in the case where the base point calibration is performed in the state where the thin film web 10 is not attached to the cut forming device 1, but the thin film web 10 is attached to the incision forming device 1. Base point calibration may be performed. For example, the cutter 5 is raised while the receiving roll 3 is receiving the thin film web 10, the cutter 5 cuts the thin film web 10, and the cutter 5 is in contact with the outer peripheral surface of the receiving roll 3 to perform base point calibration. You can also.

Further, the base point calibration may be performed based on the detection information when the contact between the cutter 5 and the spacer having a known thickness interposed between the outer peripheral surface of the receiving roll 3 and the blade portion of the cutter 5 is detected. .. At this time, the thin film web 10 may be used as a known spacer or as a part of the known spacer as long as the detection is possible and the thickness is clearly known.

When the base point correction is completed, the process proceeds to the cut forming step of the thin film web 10. FIG. 6 shows a state in which the thin film web 10 is attached to the cut forming device 1 from the state of FIG. In the state of FIG. 6, the separation distance between the receiving roll 3 and the cutter 5 is large, and the cutter 5 is not in contact with the thin film web 10, but in the cutting forming step, it is between the receiving roll 3 and the cutter 5. The separation distance is maintained at a predetermined distance at which the thin film web 10 can be cut by the cutter 5.

The base point of the predetermined distance is the calibration point determined by the base point calibration described above, and is a reference point to be set to zero. The control means 20 moves the actuator movable portion 8 by the actuator 6 so that the separation distance between the receiving roll 3 and the cutter 5 becomes a predetermined distance with respect to the calibration point. FIG. 7 shows a state in which the cutter 5 is raised to a position where the thin film web 10 can be cut. By transferring the thin film web 10 to the downstream side in the state of this figure, the cutter 5 cuts into the thin film web 10. Is formed.

As described above, in the present embodiment, the friction generated between the thin film web 10 and the receiving roll 3 while maintaining the distance between the receiving roll 3 and the cutter 5 by adjusting the arrangement position of the angle adjusting roll 2. The resistance can be adjusted. FIG. 7 shows a state in which the arrangement position of the angle adjusting roll 2 is adjusted to adjust the contact state between the thin film web 10 and the receiving roll 3. The arrangement position of the angle adjusting roll 2 in FIG. 7 has moved upward as compared with FIG. 6, and the inclination angle of the thin film web 10 has also increased between the angle adjusting roll 2 and the receiving roll 3.

According to the present embodiment, as described above, the accuracy of the cutting depth of the cutter 5 is increased and the accuracy is stable. Therefore, it is possible to cut while maintaining the cutting depth required for easy cutting by hand. A thin film web 10 having breakability can be stably obtained.

The inventors of the present application operated the notch forming apparatus 1 having the configuration shown in FIG. 1, continuously cut a 30 μm polypropylene at a notch depth of 25 μm, and wound it up to 30,000 m. Even if it continued to be cut, it could be cut stably, and the cut was too deep to make holes in the film. The wound film could be torn by hand along the notch, and the cut surface was straight and beautiful.

Although the present invention has been described above, the present invention is particularly useful as a technique for imparting a cut line to a packaging film such as a packaging bag or a bottle label. The cutting mechanism according to the present invention may be incorporated into a part of equipment having a mechanism for transferring a thin film web, such as a rewinding machine, a film forming machine, a printing machine, and a slitter.

Moreover, the said embodiment is an example, and may be changed as appropriate. For example, in FIG. 1, the actuator 6 is located at the lower part of the receiving roll 3, but the position is not limited to this, and even if the vertical position is replaced, the actuator 6 is laterally and obliquely to the receiving roll 3. It does not matter if it is located in the direction. Further, the position of the angle adjusting roll 2 is not limited to the position shown in the drawing, and may be replaced with the position of the guide roll 4 or the guide roll 4 may be replaced with the angle adjusting roll 2 and arranged at two places.
