Description

  The present invention relates to a sheet cutting method including a step of punching and cutting a sheet having an arbitrary shape from a sheet.

  As a method of punching and cutting a sheet-like material to be cut such as a plastic film, corrugated paper, and a liquid crystal substrate into a predetermined shape, punching with a rotary die cutter and punching with a Thomson blade are known. The rotary die cutter has a die cut roll and an anvil roll formed with a convex blade shape on the outer peripheral surface, and by pressing the tip of the blade die formed on the die cut roll against the outer peripheral surface of the anvil roll, The material to be cut interposed between the die cut roll and the anvil roll is cut. The rotary die cutter has high punching accuracy and is suitable for high-speed production. However, the rotary die cutter is expensive and has a drawback that maintenance work is not easy because it is complicated in apparatus. On the other hand, punching with a Thomson blade is widely adopted because it does not become complicated in terms of equipment and the equipment cost can be kept low.

  In the punching process using a Thomson blade, a cutting blade formed by bending a strip-shaped Thomson blade into a punching shape is used. As for the punching shape, the cutting edge is generally continuous in a ring shape, and can be a desired shape depending on the application, in addition to a rectangle and a circle. The cutting die for fixing the cutting blade is formed with a punched groove, and the Thomson blade is fitted into the groove and fixed. For punching with a Thomson blade, the cutting die is placed so that the cutting edge of the Thomson blade is in a straight line parallel to the surface of the workpiece, and the workpiece is placed on the receiving table. Is moved to a state where the Thomson blade touches the cradle, and the entire length of the blade tip of the Thomson blade is simultaneously pressed against the material to be cut to punch and cut the material to be cut.

  Punching with a Thomson blade has a lower punching accuracy than punching with a rotary die cutter, and if the cradle receiving the Thomson blade is a hard material such as metal, a punching defect occurs and There is a disadvantage in that a part of the blade tip hits the workpiece first, and the blade is damaged due to a phenomenon in which the entire length of the blade does not hit the workpiece simultaneously.

  Techniques have been proposed that take into account such drawbacks of punching with a Thomson blade. For example, Patent Document 1 describes that a material (spring, urethane resin, or the like) that absorbs an impact received from a cutting blade is provided behind the cradle of the cutting blade (the surface opposite to the surface that receives the cutting blade). Has been. Further, in paragraph [0002] of Patent Document 2, in molding trimming in which a heat-softened thermoplastic sheet is molded by differential pressure molding and trimmed, trimming of the thermoplastic sheet is performed using a trimming machine equipped with a Thomson blade. When performing, it describes that trimming is performed by pressing a Thomson blade against a receiving plate made of a resin such as polypropylene against a cutting portion of a thermoplastic sheet. In addition, when the Thomson blade is replaced due to wear or the like, it is necessary to press the Thomson blade evenly against the thermoplastic sheet, so that it is described that an uneven work for finely adjusting the height of the blade is performed. Yes.

  Further, in Patent Document 3, the Thomson blade is moved in the transfer direction of the sheet to be cut transferred by the conveying belt, and the Thomson blade is lowered so as to approach the cut surface of the cradle and transferred to the cut surface. A sheet cutting apparatus for cutting a sheet to be cut with a Thomson blade is described. The cutting apparatus described in Patent Document 3 enables cutting of the cut sheet with a Thomson blade without stopping the transfer of the cut sheet. According to this cutting apparatus, “the cut sheet is received. Tact time is shortened compared with a cutting device that transfers to the cutting surface of the table, stops the transfer, cuts the sheet to be cut with a Thomson blade, and then transfers the sheet to be cut next. It is said that cutting with high accuracy is possible. Further, in paragraph [0016] of Patent Document 3, a sheet to be cut is laminated through a conveying belt, and the cutting edge of the Thomson blade is moved until it slightly bites into the conveying belt to cut the sheet to be cut. The transport belt can prevent damage to the blade tip of the Thomson blade.

  Since the technique described in Patent Document 1 may cause cutting failure unless the pressing force of the cutting blade against the material to be cut is increased to some extent, it is necessary to apply a large pressing force to the cutting blade during cutting. Thomson blades do not last as long as expected. In addition, the technique described in Patent Document 2 is based on repeated trimming using a trimming machine equipped with a Thomson blade, and a resin-made backing plate such as polypropylene that receives the Thomson blade is damaged and deteriorated. Degradation may damage the Thomson blade, and will not substantially extend the life of the Thomson blade. Further, in the technique described in Patent Document 3, the Thomson blade bites into the conveying belt which is a constituent member of the cutting device every time the material to be cut is cut, so that the deterioration of the conveying belt is accelerated and the life of the device is shortened. There is a fear.

  Accordingly, an object of the present invention is to provide a sheet processing method that is highly reliable in punching and can extend the life of the apparatus.

  The present invention is a sheet processing method comprising a step of unwinding a sheet to be cut wound in a roll shape, and punching and cutting a sheet from the sheet to be cut, which is wound in a roll shape A backing sheet is unwound, and the backing sheet is superposed on one side of the sheet to be cut which has been separately unwound to obtain a laminated sheet, and the laminated sheet is received by a cutting blade fixedly installed on a cutting die and the cutting blade When the portion to be punched of the cut sheet in the laminated sheet being conveyed reaches between the cutting blade and the cradle, the conveyance of the laminated sheet is stopped. In the stationary laminated sheet, the cutting die is moved toward the other surface side of the cut sheet, and the laminated sheet is pressed with the cutting blade, thereby punching and cutting a planned punching portion of the cut sheet The stand In, subjected to half-cut which does not cut completely 該台 paper by providing a method of processing sheet is obtained by solving the above problems.

  Moreover, this invention is a processing apparatus used for the processing method of the said sheet | seat, Comprising: The cutting blade fixedly installed in the cutting die, The receiving stand which receives the said cutting blade, The mount wound in roll shape, and roll shape Each of the wound mounts is unwound in one direction and transported between the cutting blade and the cradle while superposing them into a laminated sheet, and the transporting means comprises the laminated sheet When the scheduled punching portion of the cut sheet reaches between the cutting blade and the cradle, the conveyance of the laminated sheet is stopped, and the laminated sheet can be stopped on the cradle. The above-described problems are solved by providing a processing apparatus.

  According to the present invention, it is possible to perform punching with high accuracy and extend the life of the apparatus.

  Hereinafter, the sheet processing method of the present invention will be described with reference to the drawings based on preferred embodiments thereof. FIG. 1 shows a processing method according to the first embodiment of the present invention. The processing method of the first embodiment includes a step of unwinding the cut sheet 1 wound in a roll shape and punching and cutting the sheet 1a from the cut sheet 1, more specifically, The following steps A to D are provided.

Sheet laminating step A: A base sheet 2 wound in a roll shape is unwound, and the base sheet 2 is superposed on one surface side of the sheet 1 to be cut which is separately unwound to obtain a laminated sheet 3.
Punching process B: The sheet 1a is punched and cut from the cut sheet 1 in the laminated sheet 3 obtained in the sheet laminating process A.
Collection process C: The punching waste 1b generated by the punching and cutting of the cut sheet 1 in the punching process B is wound up and collected.
Commercialization process D: The sheet 1a obtained by punching and cutting the cut sheet 1 in the punching process B and the mount 2 'that has been half-cut in the punching process B are combined after the recovery process C, and both 1a , 2 ′ as a material.

  The apparatus configuration for carrying out the processing method of the first embodiment will be described with reference to FIG. 1. The cutting apparatus 10 receives a Thomson blade 12 as a cutting blade fixedly installed on the cutting die 11 and a Thomson blade 12. A cradle 13 is provided. The cutting die 11 is provided above the cradle 13 so as to face the cradle 13 and can be moved up and down toward the cradle 13 by a drive mechanism (not shown) such as a hydraulic cylinder. The Thomson blade 12 is formed by bending a band-shaped blade into a predetermined punching shape, and is fitted into a groove (not shown) provided on the surface facing the cradle 13 of the cutting die 11 and fixed. Has been. The basic configuration of the cutting device 10 itself is the same as a known one. Examples of the material for forming the cradle 13 include hard materials such as metals and ceramics; soft materials such as resins.

  Further, the cutting device 10 includes a cutting depth adjusting mechanism (not shown) that finely adjusts the lifting distance of the cutting die 11 by the driving mechanism. By operating the cutting depth adjusting mechanism, the Thomson The cutting depth in the material to be cut formed by the blade 12 can be adjusted. For example, when a packaging material is used as the mount 2, the incision depth of the half cut applied to the packaging material is preferably in the range up to 30 μm of low density polyethylene (LDPE) which is a seal layer. What can adjust 30 micrometers by one rotation is preferable. The cutting die 11 is provided with a Thomson blade inclination adjusting mechanism (not shown) that finely adjusts the inclination of the Thomson blade 12, and the cutting depth is also adjusted by operating the Thomson blade inclination adjusting mechanism. can do.

  The sealing device 20 is a reciprocating sealing device including a processing portion 21 and a receiving portion 22 that can move relative to each other in a direction approaching and separating from each other (vertical direction in FIG. 1). By feeding the workpiece between the processing portion 21 and the receiving portion 22 while reciprocating in the direction, a part or all of the workpiece can be welded. As the sealing device 20, a known device such as a heat seal or an ultrasonic seal can be used without particular limitation.

  The processing method of the first embodiment is performed as follows using the apparatus configuration described above. First, in the sheet stacking step A, a conveying means (not shown) is operated to unwind the cut sheet 1 wound in a roll shape, and conveys the sheet to the cutting device 10 in a direction (MD) indicated by a symbol X in the drawing. To do. Separately, a conveying means (not shown) is operated to unwind the mount 2 wound in a roll shape, and the mount 2 is stacked on the one surface (lower surface) side of the sheet to be cut 1 being conveyed before the cutting device 10. Together, the laminated sheet 3 is obtained. In the laminated sheet 3, the cut sheet 1 and the mount 2 are simply overlapped, and the two 1 and 2 are not joined. However, the cut sheet 1 and the mount 2 may be joined.

  The laminated sheet 3 thus obtained is conveyed between the Thomson blade 12 and the cradle 13 in the cutting device 10. When the laminated sheet 3 is conveyed, the sheet to be cut 1 and the mount 2 constituting the laminated sheet 3 have the same conveying speed. When the part to be cut of the cut sheet 1 in the laminated sheet 3 being conveyed reaches between the Thomson blade 12 and the cradle 13, the operation of the conveying means (not shown) is stopped to convey the laminated sheet 3. Stop.

  Next, in the punching process B, the drive mechanism (not shown) is operated to move the cutting die 11 to the other surface (upper surface) side of the cut sheet 1 in the laminated sheet 3 in which the conveyance is stopped and is stationary. The laminated sheet 3 is pressed by the Thomson blade 12 fixedly installed on the cutting die 11. With this pressing, the Thomson blade 12 punches and cuts a portion to be punched of the sheet 1 to be cut, and a half cut that does not completely cut the mount 2 is applied to the mount 2. In the figure, a board that has been half-cut (hereinafter also referred to as a half-cut board) is indicated by reference numeral 2 '. In the first embodiment, the cutting die 11 is moved downward (one cutting operation by the Thomson blade 12) B1 (see FIG. 1 (b)) from the cut sheet 1 in a substantially L shape in plan view. Two sheet bodies 1a having a shape are obtained. After the punching and cutting, the cutting die 11 is lifted by the drive mechanism together with the Thomson blade 12 and returned to a predetermined standby position, waits until the next planned punching site arrives, and thereafter repeats the above-described operation.

  As described above, in the punching process B, the cut sheet 1 is completely cut (full cut) by the Thomson blade 12, whereas the mount 2 overlapped below the cut sheet 1 is not completely cut but is half cut. A notch that is shallower than the thickness of the mount 2 is only cut into one surface of the mount 2 (the surface facing the cut sheet 1). Accordingly, a cutting groove corresponding to the shape of the cutting edge of the Thomson blade 12 is formed on the surface of the half-cut mount 2 ′ facing the cut sheet 1. By performing such a half-cut of the mount 2, the punching process of the cut sheet 1 is stabilized. The half-cut of the mount 2 means that a cut is formed over the entire circumference of the cut portion of the cut sheet 1 on the mount 2, and further, the Thomson blade 12 is cut by cutting the mount 2. This reduces the load at the time of cutting with respect to the cutting edge of the blade and extends the life of the blade itself. Moreover, it becomes difficult to generate | occur | produce the position shift of the lamination sheet 3 (sheet 1 to be cut, mount 2) resulting from cutting, and the stability of the processing after the punching process B (product manufacturing process) or the next punching and cutting is increased. . Here, the positional deviation is less likely to occur because the cut sheet 1 to be cut is conveyed together with the half-cut mount 2 ′ by performing the half-cut on the mount 2, and thus the positioning is not shifted. is there. If the mount 2 is fully cut together with the cut sheet 1, there is a problem that the cut sheet 1 that has been fully cut is detached from the mount 2 when the cut sheet 1 and the mount 2 are not joined. May occur. In addition, since the mount 2 subjected to the half cut is not a component of the processing apparatus, even if the mount 2 is half cut, the processing apparatus does not deteriorate. On the other hand, since the technique described in Patent Document 3 causes the Thomson blade to bite into the conveying belt that is a constituent member of the cutting device, there is a risk of causing deterioration of the device.

  In the first embodiment, the half-cut mount 2 ′ is transported in a state where the sheet body 1 a is placed in the processes after the punching process B (collection process C, product manufacturing process D), and finally the sheet It is used as a packaging material for packaging the leaf body 1a. Therefore, the degree of half-cutting (degree of cutting) can withstand such use in each step after the punching step B is performed by the half-cut mount 2 '. It is desirable to adjust to the range. From such a viewpoint, the ratio (T1 / T) between the cut depth T1 formed by the half cut and the thickness T of the mount 2 before the half cut in the half cut mount 2 ′ is preferably 10 to 30 μm. It is. The cutting depth T1 is adjusted by operating the cutting depth adjusting mechanism, the Thomson blade inclination adjusting mechanism (none of which are shown), and the like in consideration of the type and thickness of the sheet 1 and the mount 2 to be cut. be able to. Note that, when the dedicated half-cut mount 2 is used, the cutting depth is set in accordance with the characteristics of the mount.

  Next, in the collecting step C, as shown in FIG. 1A, the punching waste 1b generated by the punching and cutting of the cut sheet 1 in the punching step B is taken up and collected. When the punched residue 1b is wound up and collected from the laminated sheet 3, the punched sheet 1a and the half-cut mount 2 'that supports the sheet 1a from below remain in the processing line.

  Next, in the product production step D, the sheet 6a and the half-cut mount 2 'are combined to produce a product 6 made of both. The product production process D includes a sealing process D1 using the sealing device 20, and a cutting process D2 that cuts the belt-like sheet into a predetermined length. Specifically, as shown in FIG. 1 (a), first, the conveying means (not shown) is operated to unwind the product raw material sheet 4 wound in a roll shape, and in the half-cut mount 2 'being conveyed. The product raw material sheet 4 is superposed on the placement surface side of the single wafer 1a to obtain a laminated sheet 5. The laminated sheet 5 is a belt-like sheet in which a plurality of sheets 1 a are interposed between the half-cut mount 2 ′ and the product raw material sheet 4, and each component 2 ′, 1 a, 4 of the laminated sheet 5. Are superimposed on each other, not joined.

  Next, using the sealing device 20, a predetermined portion of the belt-shaped laminated sheet 5 (the overlapping portion of the half-cut mount 2 'and the product raw material sheet 4) is welded to form the seal portion 23 (sealing step D1). As shown in FIG. 1B, the seal portion 23 has a quadrangular shape in plan view, and surrounds the two sheets 1a. By the sealing process of the laminated sheet 5, a sealed space for accommodating the two sheets 1 a is formed between the half-cut mount 2 ′ and the product raw material sheet 4. The half-cut mount 2 ′ and the sheet 1a is integrated.

  Next, the belt-like laminated sheet 5 is cut using a cutter 30 in a direction (CD) orthogonal to the longitudinal direction (conveying direction, MD) to obtain a sheet laminated sheet 6 (cutting step D2). The cutter 30 is a normal push-off type cutter or the like. The single wafer laminated sheet 6 obtained in this way is a product 6 that can be marketed as it is.

  The product 6 is an individual package of the sheet 1a formed by packaging the sheet 1a with a half-cut mount. Specifically, the product 6 is a flat product in which two sheets 1a are arranged in the plane direction between one half-cut mount 2 'and one product material sheet 4. The space between the two sheets 2 'and 4 is a sealed space in which the two sheets 1a are accommodated. Thus, in this embodiment, since the mount 2 for increasing the reliability of the punching process and extending the life of the processing apparatus is the material of the final product, it is a useless mount that is only half-cut and discarded. The production cost can be kept low.

  As a specific example of the product 6, an individual package of a heat generating sheet capable of generating heat by contact with air is given. The heat generating sheet is preferably used for promoting blood circulation throughout the body by being worn on the waist or shoulders of a human body. In the individual package, the sheet 1a corresponds to the heat generating sheet, and the half-cut mount 2 'and the product raw material sheet 4 correspond to packaging materials for packaging the heat generating sheet, respectively. As this heat_generation | fever sheet | seat, the thing as described in Unexamined-Japanese-Patent No. 2003-102761 which concerns on an earlier application of this applicant can be used, for example.

  When the product 6 is an individual package of the heat generating sheet, a non-breathable sheet that does not allow oxygen and water vapor to pass through is preferably used as the half-cut mount 2 'and the product raw material sheet 4 (packaging material), respectively. Examples of such a sheet material having oxygen / water vapor barrier properties include metal thin films such as aluminum foil, silica-deposited films, aluminum-deposited films, polyvinylidene chloride, etc., and particularly those having at least an aluminum foil layer. (Including aluminum foil itself) is preferable in terms of oxygen / water vapor barrier properties. Moreover, the thickness of the half-cut mount 2 'as the packaging material is preferably 10 to 30 µm from the viewpoint of more reliably performing the above-described half-cut.

  According to the processing method of the first embodiment, the laminated sheet 3 in which the mount 2 is arranged under the cut sheet 1 is pressed with the Thomson blade 12 from the cut sheet 1 side. The punching part is punched and cut and the mount 2 is half-cut, so the punching operation is stable, the punching process is performed with high precision, and the position of each material after punching is not likely to shift. In the integration process by the sealing device 20 after the process, the inconvenience that the sheet body 1a overlaps the sealed portion and a sealing failure occurs is prevented. Further, damage to the Thomson blade 12 can be suppressed, and its life can be extended.

  Moreover, since the processing method of the first embodiment performs cutting (punching and half-cutting) of the laminated sheet 3 with the Thomson blade 12 in a state where the laminated sheet 3 is stationary, it is described in Patent Document 3. In addition, the cutting device has a simple mechanism compared with the case of cutting the cut sheet with a Thomson blade without stopping the transfer of the cut sheet. This is advantageous.

  Further, according to the processing method of the first embodiment, by recovering the punched debris 1b generated by the cutting with the Thomson blade 12, the conveyance stability of the workpiece in the subsequent process is increased, and the position deviation of the workpiece is increased. Is difficult to occur, and high-precision machining can be performed. In addition, since the mount 2 is a material of the product 6 finally obtained by this processing method, there is no useless mount that is half-cut and discarded, and the manufacturing cost of the product 6 is kept low. Can do. The processing method of the first embodiment is a processing method that fully utilizes the features of punching with a Thomson blade, and is particularly effective in the manufacture of a small variety of products.

  Next, another embodiment of the present invention will be described. Regarding other embodiments described later, components different from those of the first embodiment described in detail above are mainly described, and the same components are denoted by the same reference numerals and description thereof is omitted. The description of the first embodiment is applied as appropriate to components that are not particularly described.

  FIG. 2 shows a processing method according to the second embodiment of the present invention. The processing method of the second embodiment is different from the first embodiment in the product production step D. That is, in the product production process D of the second embodiment, first, in the sealing process D1, a plurality of circular sheets 1a are interposed between the half-cut mount 2 'and the product raw material sheet 4 in plan view. For the belt-like laminated sheet 5 formed as above, the sealing device 20 is used to form a circular seal portion 24 that surrounds each sheet body 1a individually in plan view.

  Next, in the cutting step D2, using the cutting device 10 provided with the Thomson blade 12, the central portion of the belt-like laminated sheet 5 is punched and cut into an elliptical shape so as to surround the two sheets 1a (FIG. 2 (b)). The punching process in the cutting step D2 is to completely cut the entire laminated sheet 5 in the thickness direction, and the half cut performed in the punching step B is not performed in the cutting step D2. Therefore, by the punching process in the cutting step D2, the product raw material sheet 4 is separated into the elliptical sheet body 4a and the punched residue 4b in a plan view, and the half-cut mount 2 ′ has an elliptical shape in the plan view. It isolate | separates into sheet | seat body 2a 'and punching dregs 2b'.

  Next, in the collecting step D3, as shown in FIG. 2A, the punched waste 4b of the product raw material sheet 4 is wound up and collected from the laminated sheet 5, and the punched waste 2b 'of the half-cut mount 2' is wound up. to recover. Thereby, only the product 7 remains on the processing line.

  In the product 7, the two sheets 1 a of the cut sheet 1 are arranged in the plane direction between the sheet 2 a ′ of the half-cut mount 2 ′ and the sheet 4 a of the product raw material sheet 4. The product is substantially the same as the product 6 obtained in the first embodiment, except that the seal portion 24 is formed so as to individually surround the two sheets 1a. is there. According to the second embodiment, the same effect as that of the first embodiment is achieved.

  In addition, in the cutting process D2 in the second embodiment, half-cutting was not performed, but half-cutting can also be performed. The principal part of an example of the processing apparatus which can be used when performing a half cut by the cutting process D2 in a 2nd embodiment is shown by FIG. When half-cutting is performed in the cutting step D2 in the second embodiment, as shown in FIG. 3, a conveying means (not shown) is operated to unwind the mount 15 wound in a roll shape and before the cutting device 10. After the backing sheet 15 is superimposed on the lower surface side of the laminated sheet 5 being conveyed, the entire laminated sheet 5 is completely cut in the thickness direction by the Thomson blade 12 in the cutting device 10 and half-cut is applied to the backing sheet 15. Apply. After the cutting with the Thomson blade 12, the mount 15 'subjected to the half cut is wound and collected.
