Description of the Invention: [Technical Field of the Invention] [1] The present invention relates to a cutting device for a sheet, and more particularly to setting a cutting edge on a so-called through shaft. A device that lowers the knife and cuts the sheet. [Prior Art] In order to cut a sheet composed of a resin sheet or a metal foil or a composition of the resin sheet or the metal 4 into a narrower width, the upper edge of the round knife is often passed through The cutting blade group formed by the lower blade is cut. In the cutting using such a cutting blade group, two types of cutting methods are known as shown in Fig. 2 . The cutting method shown in Fig. 1(A) is to cut the sheet 3 through the upper blade 1 and the lower blade 2 (in the illustrated example, the active material 3b, 3c is held by the metal 3a) When the thickness of each surface side is about 100 / zm for the electrode sheet), the side surfaces of the upper blade 1 and the lower blade 2 are brought into contact with each other (that is, the axial clearance of the two blades is zero). It is called a so-called zero clearance cut. On the knife! A predetermined amount of overlap 4 (for example, an amount of overlap of about 100 to 200) is given between the top end and the top end of the lower blade 2. The cutting method shown in Fig. 1(b) is called so-called cutting with a predetermined gap 5 (for example, a gap of several tens of tens/zm) between the side faces of the upper blade 1 and the lower blade 2. The cutting method of the clearance cut. The amount of overlap 4 between the tip end of the upper blade 1 and the tip end of the lower blade 2 is often set to the same degree as in the case of the zero-gap cutting method. In any of the above-described cutting methods, one of the ones before cutting is required. 100140047 The position of the blade is set at the target position for the other blade, and the relationship between the two-knife bit form number A0101 page 3/24 pages 201223667 is set in the specified relationship. In particular, in the case where the gap between the side faces of the two blades is zero or the required gap is provided as described above, it is necessary to slightly adjust the position of one of the blades to the axial direction of the other blade. In order to position the cutting edge of one of the cutting edges at a predetermined position, a plurality of cutting edges may be arranged in the axial through-shaft mode for a substantially supported through-shaft, usually A spacer or the like that is fitted to the through-axis is used to determine the axial position of each blade and the interval between the blades (corresponding to the cutting width of the sheet). However, in this case, since the axial position of the blade is mechanically determined by the spacer or the like, the fine adjustment (fine adjustment of the gap amount) in the subtle axial position is particularly the case of the gap cutting method described above. In the case of the request, it is usually not possible to respond. On the other hand, in the case where an individual blade unit is provided in each individual tool unit and each unit is adjusted in the axial direction and the axial position of the blade is adjusted in the individual tool unit mode, the shaft can be rotated by each blade. The micro-adjustment of the position, but the individual cutter units have to take a certain size in the axial direction, so the spacing between adjacent blades (the width of the cut of the sheet) cannot be made too narrow, and the narrow width cannot be correspondingly required. The situation of the cut off. Further, since the support of the blade in the individual tool unit is often constituted by the cantilever support structure in the axial direction, the support portion of the blade is weak to vibration or disturbance, and the deflection accuracy of the blade edge is limited. In this case, the through-shaft method can be easily cut to a relatively narrow width by using a spacer having a narrow width or the like, and the through-shaft is configured by a simple support structure, so that the rigidity of the through-shaft and the support of the blade are supported. The rigidity is very high and the deflection accuracy of the blade is very high. In the gap cutting method, it is known that it can be set according to the object to be cut. 100140047 Form No. A0101 Page 4 of 24 1003463783-0 201223667

The basic 疋4 is the premise that the blades are in contact with each other by the pressing force. There is also the shortcoming of the shortness of the knife (4) poetry. Therefore, if the advantage of the through-axis method of the simple support can be maintained, if the cutting method is adopted, the device close to the rational state can be realized, but this has not been found yet. A cutting device for a sheet material. A conventional technique, for example, a technique suitable for a side trimmer (a side trimmer) is known as an axial position adjusting mechanism of a knife blade described in Patent Documents i and 2, but both The mechanism for directly or indirectly supporting the blade itself to be adjusted in the axial direction is far from the cutting device of the above-described preferred form. Since it is not a structure in which the blade is disposed on the penetrating shaft that is simply supported, But become a cantilever or The support shape of the cantilever is close to the limit of the deflection of the blade, and since it is not a structure in which a plurality of blades can be provided on one axis, there is no cut that cannot be cut into a plurality of columns or cannot correspond to a narrow width. [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. - 0 201223667 [0003] Therefore, in view of the above-described circumstances, it is an object of the present invention to provide an advantage that at least one of the blades can be slightly adjusted to the other blade while maintaining the advantage of the through-shaft method of the simple support. In the axial direction, the cutting device of the sheet which is cut from the zero gap to the desired gap cutting mode and which is close to the ideal form can be freely selected. In order to solve the above problems, the cutting device for the sheet according to the present invention is The upper blade having a predetermined position in the axial direction of one of the shafts of the pair of shafts extending in parallel supported by the simple support, and the shaft disposed on the other side The cutting blade group formed by the lower blade in the axially defined position cuts through the sheet between the pair of shafts by the cooperation of the upper blade and the lower blade, and is characterized in that the differential screw mechanism is individually transmitted ( The differential serewmechanism can support the axial position of the upper blade and the lower blade slightly adjusted. The differential screw mechanism herein refers to two feed screw mechanisms in which the screw ax is in the same direction ( The screw pitch of the feed screw mechanism has a difference, and the two feed screw mechanisms can be operated at the same time, and only the difference of the pitch is used as a mechanism for the feed control amount of the moving object, and can be utilized. For a small amount of feed control or position control mechanism. In the cutting device for a sheet according to the present invention, since the cutting blade group is disposed at a predetermined position in each axial direction of the pair of shafts that are simply supported, the advantage of the through-shaft method of the first support is first. The deflection accuracy of the part is well maintained, and a plurality of cutters can be arranged on one through shaft, so that many columns are cut off (of course, it is possible to cut with a set of cutting blade sets), and it is not necessary to The axial space of the individual tool units is known, so that it can also be cut for a narrow width. Moreover, at least one of the cutting edges (example 100140047 form number A0101 page 6 / total 24 pages 1003463783-0 201223667 as the upper knife 10,000 blade (for example

(2) It is possible to precisely set one of the cutting edges (for example, the position of the gap cutting method between the zero targets of the side ir-edges of the fine gap cutting method). By the following, each of the sighs holds the blade (for example, ^(holder)^η刃) of the knife holder (the th-fusto seat extends into a ring-shaped sleeve (thimMe) between the first-level mechanism; Positioned on the above shaft and equipped with: slidably slidably set the above-mentioned knife holder (4) to the sleeve (4) e and the above-mentioned sleeve has a pitch pitch different from the upper pitch _ the screw mechanism of the sleeve - a screw mechanism. In this differential screw mechanism, the first screw mechanism and the second screw can be used as a differential screw mechanism to function, and the cutter holder can be used for the sleeve. The position (and thus the position of the knife in the axial direction. It is also possible to fix the other side of the knife: the following knife), the above knife (for example, up; to; fine adjustment in the pumping direction) It can be easily and freely set from zero to the specified inter-gap cutting mode. In addition, the above-mentioned bushing is a well-known adjustment member in a micrometer (5) cr〇meter as a measuring instrument (a), and is a form number Α0Ι01 page 7/24 pages 1003463783-0 In addition, as exemplified in the embodiment of the embodiment to be described later, a representative form of the sheet cutting device according to the present invention is a structure in which the lower blade is fixed to the axial direction of the lower blade axis. The predetermined position, the upper blade corresponds to the position of the lower blade and is disposed on the upper blade axis, and individually supports the axial position of the lower blade through the differential screw mechanism. Moreover, in connection with the present invention In the sheet cutting device, the differential screw mechanism is at least at a position of a zero gap where the side faces of the two blades are in contact with each other, and a position exceeding a gap cutting position in which a predetermined gap is formed between the side faces of the two blades in advance. (ie, to a position beyond a predetermined gap cutting position), the axial position of the upper blade and the lower blade can be slightly adjusted. Preferably, by having the differential screw mechanism have such a range of motion, any desired cutting condition can be selected from a range of cutting from a zero gap to a predetermined gap. Whether the sides of the two blades are in contact with each other The zero gap position is difficult to determine by visual observation or the like. Therefore, the sheet cutting device according to the present invention includes detecting one of the upper blade and the lower blade that are finely adjusted by the differential screw mechanism. The zero gap position detecting means of the zero gap position in which the sides of the two cutting edges are in contact with each other in the axial position is preferable. If the zero gap position detecting means is included, the zero gap position can be correctly detected, and not only the zero gap cutting is selected. In the case of the condition, even in the case of selecting the gap cutting condition, the micro-adjustment amount generated by the differential screw mechanism can be measured using the detected zero-gap position as a reference posit ion, so that the blade in the gap cutting condition is The adjustment of the spacing between the sides can also improve the accuracy and can be easily set to the optimum conditions. 100140047 Form No. A0101 Page 8 of 24 1003463783-0 201223667 The above-described zero gap position detecting means can be used, for example, by means of detecting electrical conduction between the two blades caused by the contact between the side faces of the two blades. For example, if a circuit that can flow a small current between the two blades is formed, and the current actually flows when the side faces of the two blades are in contact with each other, it is easy and sure to apply a large force to the side surface of the tip end portion of the two blades. The ground condition is detected to be zero.
此情形上述兩刀刃間到達電性的導通狀態為止需將 兩刀刃間保持在絕緣狀態，因此可採用例如在刀刃支撑 部的規定部位被施以絕緣塗膜（insulating coating) 的構造。刀刃通常以超硬合金（sintered hard all0y)In this case, it is necessary to maintain the insulating state between the two blades until the electrical conduction between the two blades is reached.

The side surface of the blade is required to maintain the side precision required for the side precision. It is also required to have a high-hardness coating film (c〇ating iay_ er) which is not peeled off or deformed by abrasion or the like. Therefore, the insulating coating film is preferably a high-hardness coating film such as a DLC (Dam coating) or a ceramic coating. Further, the configuration of the sleeve for adjusting the amount of fine adjustment generated by the differential screw mechanism in accordance with the amount of rotation may be, for example, a configuration in which the degree of rotation of the sleeve is displayed on the outer circumferential surface of the sleeve. When the scale is set, the amount of rotation of the sleeve can be easily and correctly grasped, and the amount of fine adjustment generated by the differential agency of the shift example can be accurately controlled. Further, in order to achieve higher precision of the fine adjustment amount by the differential screw mechanism in the present invention, the spiral mechanism has no back iash, and in particular, the aforementioned first spiral mechanism and second spiral having a pitch difference. 100140047 Form No. A0101 Page 9 of 24 1003463783-0 201223667 The mechanism works better in the backless state of the spiral. In order to achieve this state, for example, it is preferable to arrange a pushing means for pushing the other side in the axial direction between the blade holder and the sleeve. In this configuration, the blade holder and the sleeve are urged by the pushing means, so that the first screw mechanism is disposed between the blade holder and the sleeve, and is disposed between the sleeve and the sleeve. The second screw mechanism is pressed in either direction and is held in a state where no backlash is generated. That is, the pushing means functions as a pressing means for the screw mechanism. Such a pushing means can be, for example, an elastic member such as a plunger or a coil spring or a 0 ring. Further, in the present invention, the upper blade or the lower blade of the cutting blade group may be formed by a blade edge which is called a so-called gang blade, and a blade having a right-angled face facing the side of the blade, but can also be used. A blade called a so-called shear blade is sharpened, and the side of the blade forms a rounded edge of a face having a right angle or an acute angle to the axis of rotation. [Effect of the Invention] According to the cutting device for a sheet according to the present invention, the deflection accuracy of the blade portion in the through-shaft method of the simple support can be favorably maintained, and it can be easily used. In accordance with the advantage of the cutting of the narrow width, the axial position of the blade can be finely adjusted by the differential screw mechanism, and the cutting method can be freely set in a wide range from the zero gap cutting to the predetermined gap cutting. Therefore, it is possible to easily and surely perform the optimum cutting for the object to be cut. [Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings, a 100140047, a form number A0101, a 10th page, a total of 24 pages, 1003463783-0 [0005] 201223667. Fig. 2 is a view showing a cutting device 1Q for a sheet relating to an embodiment of the present invention. In the cutting device (4), the lower blade shaft 12 (also shown in FIG. 3) is simply supported on the right and left fixed frames (four), and is disposed in the vertical direction with respect to the fixed frame 11 at a positive position. The left and right movable frames 13 are simply supported by the upper blade shaft 14 (also shown in Fig. 3) extending in parallel to the lower (four). As shown in FIG. 3, a plurality of lower cutting edges 15' are provided in the predetermined position at the predetermined position in the axial direction of the lower cutter shaft 12, and the upper cutter 77 shaft 14 corresponds to the axial direction of each lower cutting edge 15. The location is equipped with a plurality of 7777丨6. The upper system 16 and the lower system 15 are constituted by a combination cutting blade in the present embodiment, and the group structure of the corresponding upper blade 16 and lower blade 15 is transmitted through the upper blade (4) lower knife (10) m of the present invention. The cutting blade set of the sheet. In the example of the figure, although a cutting tool set of a complex array is arranged, only one set may be arranged. In the present embodiment, the upper cutters 16 can individually support the axial position through the differential screw mechanism π, but can also be on the side of the τ blade 15 or Q on the upper blade 16 and the lower blade force 15 A differential screw mechanism is arranged on both sides. The upper blade 7716 is threaded through the screw as shown in Figs. 3 to 5 (the bolts 19 are held by the blade holders 18a, 18, and the sleeves 20a and 18b are passed through the sleeve 20 and the spiral attached to the upper blade axis). The portion is mounted so as to be supported in the axial direction in a slidable state. The outer peripheral surface is engraved with a sleeve 22 extending in a circular shape of the scale 21 indicating the amount of rotation, and is interposed between the blade holder 18a and the sleeve. Between the cymbal holder 18a and the sleeve 22, a first screw mechanism 23 is formed, and between the sleeve 20 and the sleeve 22, a second screw mechanism 24 is formed, the first screw mechanism 23 and the first The screw mechanism 24 is configured such that the pitches are different from each other. The first-stage mechanism 23 and the second screw mechanism 24 constitute a differential screw machine 1003463783-0 100140047 Form No. A0101 Page 11 / 24 pages 201223667 Structure 17, by means of The sleeve 22 is rotated such that the blade holders 18a, 8 are further held by the upper cutters 16 of the blade holders 18a, 18b, and the sleeves 20 fixed to the upper cutter shafts 14 are finely adjusted to correspond to the above pitches. The position of the poor portion is in the axial direction. In other words, the axial position of the upper knife 16 can be borrowed from the corresponding lower cutting edge 15 * The differential touch (four) 17 is configured by fine adjustment with high precision. For example, if the pitch of one of the first screw mechanism 23 and the second screw mechanism 24 is 1 mm, and the pitch of the other is 〇. 9 mm, the sleeve can be made The 22 rotation-circle's the upper knife is set to be only 0.1 mm in the axial direction corresponding to the S-difference of the pitch. If the outer circumferential surface of the sleeve 22 is engraved, the scale 1 is equally divided. Therefore, since the scale is 1/1 〇〇 of the rotation amount, the position of the upper blade 16 can be slightly adjusted by 0·〇〇1ππη in the axial direction. By precisely adjusting the position of the upper blade 16 in this manner As shown in FIG. 1, the side of the upper blade 16 contacts the side zero gap position of the lower blade 15 to a predetermined position; t is a gap cutting position between the sides of the two blades to form a regular gap. 'The required cutting conditions can be selected and set arbitrarily accurately. Moreover, in the present embodiment, the knife holder 18a and the sleeve are disposed between the cutter holders 18a and the sleeves. a plug 25 for pushing means, the first screw mechanism 23 and the second screw mechanism 24 are passed through the plunger 25 Pressurized in the axial direction so that no backlash is generated in both the first screw mechanism 23 and the second screw mechanism 24. Accordingly, the axial position of the upper blade 16 by the above-described differential: the rotary mechanism 17 is microscopically Further, the adjustment is performed with higher precision. Further, although the illustration is omitted, the zero gap formed by the means for detecting the electrical conduction between the two blades due to the contact between the two blades 15 and 16 is provided as described above. Position detection means, because the correct form end (No. A0101 Page 12 / Total 24 pages 1〇〇3463783~ 201223667
