Description

  This aspect relates to a holder for holding a rotary blade that is used in a cutting device that cuts a sheet-like member into a predetermined width. As a sheet-like member, members, such as metal foil, paper, and a resin film, are mentioned, for example.

  As a cutting device for cutting a sheet-like member, for example, a slitter device described in JP 2010-188464 A (Patent Document 1) is known. The slitter device described in Patent Document 1 includes a cylindrical holder to which a round blade is attached. The holder has a connecting portion capable of elastic deformation and a female screw hole formed so as to intersect the connecting portion, and a bolt is attached to the hole. By tightening the bolt, the inner diameter of the holder decreases, and the holder is fixed to the rotating shaft.

  The holder according to one aspect has a cylindrical shape, a slit having a first inner surface and a second inner surface facing the first inner surface from the inner peripheral surface to the outer peripheral surface, and a first cut located on the outer peripheral surface. A main body having a notch, a first hole extending from the first inner surface to the outer peripheral surface, and a second hole extending from the second inner surface to the first notch; Moreover, it comprises a rod-shaped guide member that is held in the first hole and is located in the first hole and the second hole. And a clamp member that is positioned in the first cutout portion, engages the guide member, and has a shaft portion movable in the circumferential direction of the outer peripheral surface.

It is the schematic which shows the cutting device of one Embodiment.

  When the holder is fixed to the rotating shaft by tightening the bolt to reduce the inner diameter of the holder, the connecting portion is slightly in the direction along the center axis of the holder due to the force applied when the bolt is tightened. It can be elastically deformed. Therefore, a slight distortion occurs in the direction of the central axis in the holder. Thereby, the round blade attached to the holder is distorted, and the accuracy of cutting the sheet-like member is lowered. In recent years, since high accuracy is required for cutting the sheet-like member, the influence of the above-described distortion of the holder cannot be ignored.

<Rotating blade holder>
Hereinafter, a rotary blade holder 1 (hereinafter also simply referred to as a holder 1) according to an embodiment will be described in detail with reference to the drawings. However, each drawing referred to below shows only the main members necessary for explaining the present embodiment in a simplified manner for convenience of explanation. Accordingly, any component not shown in the drawings referred to in this specification may be provided. Moreover, the dimension of the member in each figure does not represent the dimension of an actual structural member, the dimension ratio of each member, etc. faithfully.

  As shown in FIGS. 2 to 4, the holder 1 of this embodiment is a cylindrical member that extends along the central axis X <b> 1 as a whole, and is a member to which an annular rotary blade is attached. As shown in FIGS. 5 and 8, the holder 1 of this embodiment includes a main body 3, a guide member 5, and a clamp member 7.

  The main body 3 is a cylindrical member having a slit 9, a first hole 11, and a second hole 13, for example, as shown in FIGS. 11 and 12. The slit 9 has a first inner side surface 9a and a second inner side surface 9b facing the first inner side surface 9a. The first inner side surface 9 a and the second inner side surface 9 b are located from the inner peripheral surface 3 a to the outer peripheral surface 3 b of the main body 3, respectively.

  The main body 3 has such a slit 9, and the inner diameter of the main body 3 having a cylindrical shape can be changed by elastically deforming the main body 3 to change the width of the slit. Therefore, in a cutting device unit (hereinafter also simply referred to as a unit) to which the holder 1 is attached, the holder 1 can be detachably attached to a rod-shaped shaft member.

  The first hole portion 11 extends from the first inner side surface 9 a of the slit 9 to the outer peripheral surface 3 b of the main body portion 3. The second hole 13 extends from the second inner surface 9 b of the slit 9 to the outer peripheral surface 3 b of the main body 3. The first hole portion 11 and the second hole portion 13 are portions into which the guide member 5 is inserted.

  The guide member 5 is a rod-shaped member located in the first hole portion 11 and the second hole portion 13. One end of the guide member 5 is held by the main body 3 in the first hole 11. The other end of the guide member 5 is locked to the clamp member 7.

  Moreover, the main-body part 3 in this embodiment has the 1st notch part 15 in the outer peripheral surface 3b. The clamp member 7 is located in the first cutout portion 15, and the guide member 5 is locked in the first cutout portion 15. The second hole 13 extends from the second inner side surface 9 b to the first notch 15. The clamp member 7 is used to fix the holder 1 to a rod-shaped shaft member in the unit by reducing the inner diameter of the holder 1.

  The clamp member 7 has a shaft portion 8 that is movable in the circumferential direction of the outer peripheral surface 3 b of the main body portion 3. And the clamp member 7 has a part from which the distance from the central axis X2 of the axial part 8 in the clamp member 7 differs in the 2nd inner surface 9b side. The axial direction of the central axis X <b> 2 of the shaft portion 8 of the guide member 5 is the same as the axial direction of the central axis X <b> 1 of the holder 1.

  As shown in FIG. 6, the clamp member 7 has a head portion 17 that locks the guide member 5, and has portions having different distances from the central axis X <b> 2 of the shaft portion 8 of the guide member 5. “Has” means that the head 17 has different thickness portions. In the present embodiment, the head 17 has a cam shape. The head 17 has a first region 17a and a second region 17b so as to be eccentric from the central axis X2 of the shaft portion 8. A thickness R1 from the central axis X2 of the shaft portion 8 to the outer surface in the first region 17a is smaller than a thickness R2 from the central axis X2 of the shaft portion 8 to the outer surface in the second region 17b.

  Specifically, the head 17 of the clamp member 7 in this embodiment has an elliptical shape in contact with the main body 3 when viewed in the direction along the central axis X2. Thus, since the head 17 has an elliptical shape, when the clamp member 7 is moved, the clamp member 7 causes the main body 3 (the surface on the opposite side of the second inner side surface 9b. Hereinafter, simply referred to as the opposite surface 10 to be described. .) Is pushed, and the interval between the slits 9 is reduced.

  When the state shown in FIG. 6 is a state in which the clamp member 7 is tilted, the state in which the clamp member 7 is raised will be described with reference to FIG. In the state where the clamp member 7 is erected as shown in FIG. 7, the first region 17 a approaches or gently contacts the opposite surface 10. As described above, the thickness R1 in the first region 17a is relatively small. Therefore, when the clamp member 7 is erected, the width of the slit 9 can be secured widely. Thereby, since the internal diameter of the main-body part 3 becomes large, the holder 1 can be penetrated to the rod-shaped shaft member in a unit. In this way, the holder 1 can be inserted into the shaft member in the state of FIG. 7, and the holder 1 can be fixed to the shaft member in the state of FIG. That is, it becomes detachable.

  The dashed line shown in FIG. 7 is the position of the opposite surface 10 in the state of FIG. As is apparent from the one-dot chain line, the opposite surface 10 changes by the difference δ, that is, the interval between the slits 9 changes by the difference δ.

  In the holder 1 of the present embodiment, the inner diameter of the main body 3 is changed by moving the clamp member 7 without using a screw member such as a bolt. That is, the inner diameter of the main body 3 can be reduced by the guide member 5 and the clamp member 7 without using a screw member. Therefore, it is possible to avoid a force in the direction along the central axis X <b> 1 generated when the screw member is tightened from being applied to the main body 3. Thereby, since the distortion of the holder 1 in the direction along the central axis X1 can be reduced, the distortion of the rotary blade due to this distortion is reduced, so that the cutting accuracy by the cutting apparatus using the holder 1 of the present embodiment is increased.

  In addition, although the central axis X2 of the shaft portion 8 of the clamp member 7 in this embodiment is parallel to the central axis X1, it is not limited to such a form, and may be inclined with respect to the central axis X1. However, when the central axis X2 is parallel to the central axis X1 as in the present embodiment, the clamp member 7 can be easily attached even if the thickness of the main body 3 is thin. Can be easily moved.

  As the material of the main body 3, the guide member 5, and the clamp member 7 in the present embodiment, for example, steel or stainless steel can be used, respectively.

  In the present embodiment, the first hole portion 11 and the second hole portion 13 of the main body portion 3 each extend in a direction orthogonal to the central axis X1. Therefore, the axial direction of the guide member 5 is orthogonal to the central axis X1. By pulling down (falling down) the portion of the clamp member 7 opposite to the head 17, the inner diameter of the holder 1 is reduced. At this time, the width of the slit 9 is reduced along the direction in which the guide member 5 extends. Therefore, when the guide member 5 is positioned as described above, the distortion of the holder 1 in the direction along the central axis X1 can be further reduced.

  In the holder 1 of the present embodiment, the first rotary blade 25 can be held on the first end surface 3 c side of the main body 3. The clamp member 7 is located on the second end face 3d side opposite to the first end face 3c from the first end face 3c side facing the first rotary blade 25 in the main body 3.

  Specifically, as shown in FIG. 8, the clamp member 7 is biased and located below the main body portion 3. In FIG. 8, the main body 3 is illustrated so that the first end surface 3c side is upward and the second end surface 3d side is downward. When the clamp member 7 is positioned as described above, it is easy to secure a space between the clamp member 7 and the first rotary blade 25. For this reason, the first rotary blade 25 is unlikely to get in the way when the clamp member 7 is operated, so that the clamp member 7 can be easily moved. Therefore, the attaching / detaching work of the holder 1 to the shaft member of the unit is facilitated. Further, since the attaching / detaching work becomes easy, the possibility that the operator who performs the attaching / detaching work touches the first rotary blade 25 and is injured is reduced, and thus the safety of the attaching / detaching work is improved.

  The clamp member 7 in the present embodiment is provided with two holes 7a. When such a hole 7a is provided, an operation for opening and closing the clamp member 7 is facilitated. Specifically, the clamp member 7 can be operated by inserting a rod-shaped member into the hole 7a and operating this member. When the clamp member 7 is small, such as when the holder 1 is downsized, the operation of opening and closing the clamp member 7 is particularly easy.

  In addition to the first notch 15, the main body 3 in the present embodiment further includes a second notch 19 on the opposite side of the first notch 15 with respect to the central axis X <b> 1. .

  When the main body 3 has the second notch 19 described above, the center of gravity of the holder 1 and the central axis X1 are less likely to be separated from each other. Therefore, the vibration of the holder 1 when using the cutting device 201 can be suppressed to a low level.

  The main body 3 in the present embodiment has a groove 21 extending in the direction along the central axis X1 on the inner peripheral surface 3a in addition to the slit 9 formed from the inner peripheral surface 3a to the outer peripheral surface 3b. . Although it is possible to reduce the inner diameter of the holder 1 by moving the clamp member 7, at this time, when the main body 3 has the groove 21, the main body 3 is easily elastically deformed. Become. Therefore, it becomes easy to reduce the inner diameter of the holder 1.

  At this time, it is desirable that the groove 21 is located on the opposite side of the slit 9 with respect to the central axis X1. This is because the bias of elastic deformation of the main body 3 can be reduced when the groove 21 exists at the above position. In the present embodiment, the fact that the groove 21 is located on the opposite side of the slit 9 with respect to the central axis X1 refers to the groove 21 and the center when viewed from the side along the central axis X1 of the holder 1. It means that the axis X1 and the slit 9 are located on a straight line.

  In addition, although the groove part 21 in this embodiment is located in the inner peripheral surface 3a of the main-body part 3, you may be located in the outer peripheral surface 3b of the main-body part 3. FIG. In the present embodiment, one groove portion 21 is provided, but the number of groove portions 21 may be plural. In the case where a plurality of groove portions 21 are provided, the shift between the center of gravity of the holder 1 and the central axis X1 can be suppressed by arranging the groove portions 21 of the same size at equal intervals in the circumferential direction.

<Unit for cutting device>
The holder 1 of the present embodiment is used for a cutting device unit 101 (hereinafter also simply referred to as a unit 101). As shown in FIG. 1, the unit 101 in this embodiment includes a shaft member (first shaft member 23), a holder 1 typified by the above embodiment, and a rotary blade 25 (first rotary blade 25). One cutting blade member 27 and a rotation mechanism 29 are provided.

  The holder 1 is attached and held on the outer periphery of the first shaft member 23. In other words, the first cutting blade member 27 is inserted through the first shaft member 23. By cutting the relatively wide sheet-like member fed to the unit 101 using the first cutting blade member 27, a sheet work having a relatively small width is produced.

  In the first cutting blade member 27 in the present embodiment, the first rotary blade 25 has an annular shape. The first rotary blade 25 can suppress distortion of the first shaft member 23 in the axial direction by being held by the holder 1.

  The first rotary blade 25 is detachably attached to the holder 1 and is fixed to the first shaft member 23 via the holder 1. When the first shaft member 23 rotates, the first rotary blade 25 also rotates in accordance with the rotation of the first shaft member 23.

  As the material of the first rotary blade 25, cemented carbide, cermet, steel, stainless steel, or the like can be used.

  In addition, a first cylindrical member 31 may be attached to the outer periphery of the first shaft member 23 between the plurality of first cutting blade members 27. The first cylindrical member 31 is a member for adjusting the interval between the plurality of first cutting blade members 27. If the width of the first cylindrical member 31 is set to a width corresponding to a desired cutting width while considering the width of the first cutting blade member 27, the first cutting blade member 27 can be easily positioned. can do. In addition, although the unit 101 of this embodiment is provided with the 1st cylindrical member 31, this 1st cylindrical member 31 is not an essential structure.

  Further, the unit 101 of the present embodiment further includes a second shaft member 35, a plurality of second rotary blades 37, and a plurality of second cylindrical members 39. The plurality of second rotary blades 37 each have an annular shape centered on the central axis of the second shaft member 35, and are positioned on the outer periphery of the second shaft member 35.

  The second rotary blade 37 is attached to the rotation mechanism 29 so that the side surface thereof is in contact with the side surface of the first rotary blade 25. Since the side surface of the first rotary blade 25 and the side surface of the second rotary blade 37 are in contact with each other, a shearing force is generated between the first rotary blade 25 and the second rotary blade 37. Can be cut.

  As the material of the second rotary blade 37, similarly to the first rotary blade 25, cemented carbide, cermet, steel, stainless steel and the like can be used.

  The second shaft member 35 has a shaft parallel to the first shaft member 23 and is a rod-shaped member provided below the first shaft member 23. Therefore, the second shaft member 35 is positioned so as to overlap the first shaft member 23 when the unit 101 is viewed from above.

  The plurality of second cylindrical members 39 are located on the outer periphery of the second shaft member 35 and between the plurality of second rotary blades 37. The second cylindrical member 39 has a cylindrical shape with the axis of the second shaft member 35 as the central axis. The second cylindrical member 39 is a member for adjusting the interval between the plurality of second rotary blades 37. If the width of the second cylindrical member 39 is set to a width corresponding to a desired cutting width of the sheet-like member, the positioning of the second rotary blade 37 can be facilitated.

  The rotation mechanism 29 includes a lower plate portion 41 and a pair of side wall portions 43 fixed to the lower plate portion 41 with their main surfaces facing each other. As dimensions of the lower plate portion 41, for example, the width in the x-axis direction in FIG. 1 can be set to 400 to 2000 mm, the width in the y-axis direction can be set to 100 to 500 mm, and the width in the z-axis direction can be set to about 200 to 500 mm.

  In FIG. 1, the direction parallel to the first shaft member 23 and the second shaft member 35 is the x-axis direction, the direction orthogonal to the x-axis direction and parallel to the upper surface of the lower plate portion 41 is the y-axis direction, A direction perpendicular to the x-axis direction and the y-axis direction in FIG. 1 is the z-axis direction.

  The rotation mechanism 29 should just be the structure which has sufficient intensity | strength to hold | maintain the 1st cutting blade member 27 and the 2nd rotation blade 37 stably. Therefore, the rotation mechanism 29 is not limited to the configuration formed by the lower plate portion 41 and the pair of side wall portions 43 as in the present embodiment. For example, the rotation mechanism 29 may have a concave configuration in which the lower plate portion 41 and the pair of side wall portions 43 in the present embodiment are integrally formed.

  The pair of side wall portions 43 have a first support portion 45 and a second support portion 47 that are independent of each other. The first support portion 45 has a configuration in which a part of the pair of side wall portions 43 is cut out, and is open to one of both side surfaces and the upper surface of the pair of side wall portions 43. Similarly to the first support portion 45, the second support portion 47 has a configuration in which a part of the pair of side wall portions 43 is notched, and is formed on one of both side surfaces and the upper surface of the pair of side wall portions 43. It is open.

  The second support part 47 is located below the first support part 45. The first cutting blade member 27 is attached to the first support portion 45 in each of the pair of side wall portions 43. Further, the second shaft member 35 is attached to the second support portion 47 in each of the pair of side wall portions 43.

  When the first support portion 45 and the second support portion 47 are configured by notching the pair of side wall portions 43, the first cutting blade member 27 and the second rotary blade 37 can be easily taken in and out. Mounting of the blade member 27 and the second rotary blade 37 is facilitated.

  As dimensions of the pair of side wall portions 43, the width in the x-axis direction can be set to 10 to 60 mm, the width in the y-axis direction can be set to 100 to 500 mm, and the width in the z-axis direction can be set to about 200 to 500 mm. As the material of the lower plate portion 41 and the pair of side wall portions 43, steel, stainless steel, or the like can be used.

  The first shaft member 23 is a rod-shaped member having an axis in a direction parallel to the x-axis direction. Therefore, the first shaft member 23 is positioned so as to be parallel to the upper surface of the lower plate portion 41. The first shaft member 23 has a circular cross section perpendicular to the axial direction.

  Both ends of the first shaft member 23 are attached to the first support portions 45 of the pair of side wall portions 43. At this time, the first shaft member 23 is attached to the first support portion 45 so as to be rotatable around the axis. As dimensions of the first shaft member 23, for example, the length in the axial direction (x-axis direction) can be set to 450 to 2400 mm, and the diameter can be set to about 30 to 95 mm. As the material of the first shaft member 23, steel, stainless steel, or the like can be used.

  At both ends of the first shaft member 23, annular bearings are attached as first bearing members 49, respectively. The first shaft member 23 is held by the first support portion 45 by holding the first bearing member 49 by the first support portion 45. By providing such a first bearing member 49, the first shaft member 23 can be easily rotated while the first shaft member 23 is stably held by the first support portion 45. As a dimension of a bearing, an outer diameter can be set to about 30-95 mm.

  At both ends of the second shaft member 35, annular bearings are attached as the second bearing members 51, respectively. By holding the second bearing member 51 by the second support portion 47, the second shaft member 35 is held by the second support portion 47. By providing such a second bearing member 51, the second shaft member 35 can be easily rotated while the second shaft member 35 is stably held by the second support portion 47.

  As a dimension of a bearing, an outer diameter can be set to about 30-95 mm. The cross section perpendicular to the axial direction of the second shaft member 35 is circular like the first shaft member 23. The dimension of the second shaft member 35 may be approximately the same as that of the first shaft member 23.
