Technical Field
[0001] This invention relates to a cutting device. Background Technology
[0002] Patent Document 1 discloses a punching processing device in which bearings are provided at both ends of a die-cutting roller and a pressure roller, and bearings provided on at least one of the rollers are able to rotate freely relative to the rollers.
[0003] Patent Document 1: Japanese Patent Application Publication No. 2007-229832 Summary of the Invention
[0004] In Patent Document 1, in order to optimize the spacing between the die-cutting roller and the pressure roller (two rotating bodies), it is necessary to grind the outer periphery of the bearing into a concentric circle shape with the rotating body while the bearing is mounted on the rotating body.
[0005] To address this issue, the present invention provides a cutting device that optimizes the spacing between two rotating bodies without requiring large-scale processing.
[0006] The present invention provides a cutting device comprising: an upper rotating body having a cutting blade disposed on its outer surface; and a lower rotating body disposed below the upper rotating body and having a cutting blade disposed on its outer surface. The cutting device cuts sheet-like workpieces by meshing the cutting blades of the upper rotating body and the lower rotating body. Rotatable upper reference rollers are disposed on both outer sides of the upper rotating body in the direction of rotation axis, and rotatable lower reference rollers are disposed on both outer sides of the lower rotating body in the direction of rotation axis. A roller unit is disposed between the upper and lower reference rollers, the roller unit comprising an upper roller unit that abuts against and rotates with the upper reference roller and a lower roller unit that abuts against and rotates with the lower reference roller.
[0007] This structure optimizes the spacing between the two rotating bodies without requiring large-scale processing.
[0008] The roller unit has a support member that supports the upper roller unit and the lower roller unit. An opening is formed in the support member, which is a hole that extends through the workpiece along its width. This structure allows confirmation of the state in which the cutting blades of the upper and lower rotating bodies are engaged and the workpiece is being cut.
[0009] Upper support units are provided on both outer sides of the upper rotating body along its rotation axis, and lower support units are provided on both outer sides of the lower rotating body along its rotation axis. A column member extending vertically is provided on one side of each of the upper and lower support units along the workpiece conveying direction. An upper stretching mechanism for stretching the upper support unit along the column member and a lower stretching mechanism for stretching the lower support unit along the column member are provided on the column members. With this structure, the upper and lower support units contact the column members, enabling the upper and lower rotating bodies to be positioned along the workpiece conveying direction.

[0023] Implementation Method 1
[0024] use Figures 1-9 The cutting apparatus 1 according to Embodiment 1 will be described below. The cutting apparatus 1 is a device for cutting a sheet-shaped workpiece W using a pair of upper and lower cutting blades. The workpiece W is, for example, an electrode sheet that serves as a substrate for a lithium-ion battery. Figure 1 As shown by arrow C, the workpiece W moves from the front to the rear of the cutting device 1. Figure 1 The X-axis (negative direction) is conveyed and cut.
[0025] like Figures 1-3 As shown, the cutting device 1 has an upper unit 10, a lower unit 20, a roller unit 30, etc.
[0026] The upper unit 10 includes an upper rotating body 11, a retainer 13, a cutting blade 14, an upper reference roller 15, an upper support unit 16, and a drive motor 17.
[0027] like Figure 1 , Figure 2 As shown, the upper rotating body 11 is formed in the left and right directions ( Figure 1 It is roughly square-shaped (viewed along the Y-axis) and has a quadrangular prism shape along the left and right directions. Figure 1 Extending in the Y-axis direction. Shaft portions 16c (see reference) are respectively mounted on the outer sides of the upper rotating body 11 in the left and right directions via the upper reference roller 15. Figure 8 The upper rotating body 11 rotates about the axis center C1 of the shaft portion 16c. Figure 3 (The direction of arrow A).
[0028] like Figures 1-4 As shown, in the direction orthogonal to the rotation axis of the upper rotating body 11 ( Figure 1 Retainers 13 are respectively mounted on the four outer surfaces (in the XZ plane direction) via plate 11a. Additionally, in Figure 1 and Figure 2 The illustration of part of plate 11a and retainer 13 is omitted. Figure 3 The illustration of plate 11a is omitted in the text. (See example...) Figures 2-4 As shown, the retainer 13 has a first retainer 13a and a second retainer 13b. The first retainer 13a and the second retainer 13b are in the same rotation direction as the upper rotating body 11 ( Figure 3 Arranged in the direction of arrow A, and along the left and right directions of the upper rotating body 11 ( Figure 2 (Extends along the Y-axis direction).
[0029] like Figure 3 As shown, the first retainer 13a and the second retainer 13b hold the cutting blade 14 sandwiched between them. Additionally, in Figure 1 , Figure 2 , Figure 4 The cutting blade 14 is omitted from the illustration. The cutting blade 14 is formed in a left-right view ( Figure 3 It is roughly triangular in shape when viewed from the Y-axis direction, and along the length direction of the retainer 13 ( Figure 3 (Extends along the Y-axis direction).
[0030] like Figure 3 As shown, the first retainer 13a and the second retainer 13b, which are positioned opposite each other on their sides that clamp the cutting blade 14, narrow from the upper rotating body 11 toward the tip of the cutting blade 14, thus serving to position the cutting blade 14. The cutting blade 14 is respectively disposed on the four retainers 13, and in the rotation direction of the upper rotating body 11 ( Figure 3The arrows are arranged at 90-degree intervals in the direction of A.
[0031] like Figure 2 , Figure 8 As shown, in the direction of the rotation axis of the upper rotating body 11 ( Figure 2 Upper reference rollers 15 are respectively provided on the outer sides of the upper reference rollers 11 in the Y-axis direction. The upper reference rollers 15 are cylindrical and rotate together with the upper rotating body 11 around the axis center C1. Alternatively, the upper reference rollers 15 can also rotate independently of the upper rotating body 11. The radial outer circumferential surface of the upper reference rollers 15 is composed of an elastic body. As described later, the upper reference rollers 15 serve as the upper rotating body 11 in the vertical direction (Y-axis direction). Figure 2 It functions by positioning itself in the Z-axis direction.
[0032] like Figure 1 , Figure 4 , Figure 8 As shown, in the direction of the rotation axis of the upper rotating body 11 ( Figure 1 Upper support units 16 are respectively provided on the outer sides of both sides (in the Y-axis direction). Figure 8 As shown, the upper support unit 16 is positioned relative to the upper rotating body 11 in a direction closer to the rotation axis than the upper reference roller 15. Figure 8 The outer side (in the Y-axis direction). For example... Figure 1 , Figure 4 As shown, the upper support unit 16 is formed in a left-right direction view ( Figure 1 It is roughly square-shaped (viewed along the Y-axis).
[0033] like Figure 4 , Figure 8 As shown, the upper support unit 16 has a housing 16a, a bearing portion 16b, and a shaft portion 16c. The housing 16a forms the vertical axis of the upper support unit 16. Figure 4 (Z-axis direction) and front-back direction ( Figure 4 The outer frame portion extends along the X-axis direction. A portion extending along the left-right direction is formed in the central part of the housing 16a. Figure 4 A through hole (in the Y-axis direction) is provided, and the bearing portion 16b is fitted into the through hole. The bearing portion 16b is composed of an angular contact ball bearing assembled on the back side, and has an outer ring, an inner ring, multiple rolling elements disposed between the outer ring and the inner ring, and a retainer (not shown) that positions each rolling element in the circumferential direction. Figure 8 As shown, a shaft portion 16c is inserted through the inner circumference of the bearing portion 16b, and is fastened to the side opposite to the upper reference roller 15 of the bearing portion 16b. Figure 8 The nut 16d (on the positive Y-axis side) and the inner ring of the bearing portion 16b are fixed to the shaft portion 16c. Thus, the shaft portion 16c is rotatably supported by the bearing portion 16b, thereby rotating the upper rotating body 11.
[0034] like Figure 1 As shown, on the right side of the upper unit 10 ( Figure 1 A drive motor 17 is provided at the end of the Y-axis positive side. The drive motor 17 is connected to the right side ( Figure 1 The shaft portion 16c (on the positive Y-axis side) is connected to the shaft portion 16c, and together with the shaft portion 16c, the upper rotating body 11 rotates at a predetermined speed along... Figure 3 Rotate in the direction of arrow A.
[0035] like Figures 1-4 As shown, a lower unit 20 is provided below the upper unit 10. The lower unit 20 includes a lower rotating body 21 (including a plate 21a), a retainer 23 (including a first retainer 23a and a second retainer 23b), a cutting blade 24, a lower reference roller 25, a lower support unit 26 (including a housing 26a, a bearing portion 26b, and a shaft portion 26c), and a drive motor 27. These components of the lower unit 20 are substantially the same in shape, structure, or function as their corresponding components in the upper unit 10, and therefore descriptions are omitted. The difference between the lower unit 20 and the upper unit 10 is the direction of rotation of the rotating body. Figure 3 As shown, the upper rotating body 11 of the upper unit 10 rotates in the direction of arrow A, while the lower rotating body 21 of the lower unit 20 rotates in the direction of arrow B, which is opposite to the direction of arrow A. Moreover, the upper rotating body 11 and the lower rotating body 21 rotate so that they are oriented in the same direction as the conveying direction of the workpiece W (direction of arrow C).
[0036] like Figure 3 As shown, the rotation angles of the upper rotating body 11 and the lower rotating body 21 are adjusted so that the four cutting blades are aligned with each other and rotate at the same speed. That is, the rotation angles of the upper rotating body 11 and the lower rotating body 21 are adjusted so that the four cutting blades are in the same phase.
[0037] like Figure 3 As shown, workpiece W is conveyed between upper rotating body 11 and lower rotating body 21. If the cutting blade 14 of upper rotating body 11 engages with the cutting blade 24 of lower rotating body 21, workpiece W is cut. Specifically, the upper rotating body 11 is oriented downwards (…). Figure 3 The cutting blade 14 (in the negative Z-axis direction) cuts into the upper portion of the workpiece W in the thickness direction. Furthermore, the lower rotating body 21 faces upwards (…). Figure 3 The cutting blade 24 (in the positive Z-axis direction) cuts into the lower portion of the workpiece W in the thickness direction. If the upper and lower portions of the workpiece W in the thickness direction are cut by the cutting blade, a crack is generated between the upper and lower cut portions, and the workpiece W is cut.
[0038] like Figure 2As shown, a roller unit 30 is disposed between the upper reference roller 15 of the upper unit 10 and the lower reference roller 25 of the lower unit 20. The roller units 30 are respectively disposed in the left and right directions of the cutting device 1. Figure 2 (the two ends of the Y-axis direction).
[0039] like Figure 5 , Figure 6 As shown, the roller unit 30 has a support member 31 that supports the first upper roller unit 40a, etc. The support member 31 has: a pair of planar portions 32a and 32b; a first connecting portion 36a and 36b; and a second connecting portion 37a and 37b. The pair of planar portions 32a and 32b are respectively formed in a left-right direction view (…). Figure 5 Viewed along the Y-axis, it is roughly H-shaped and flat. A pair of planar portions 32a and 32b face each other along the left-right direction. Figure 5 (Arrangement along the Y-axis).
[0040] like Figure 5 As shown, on a pair of planar portions 32a and 32b, respectively, there are shaped portions arranged along the thickness direction ( Figure 5 The first upper shaft hole 33a, the second upper shaft hole 33b, the first lower shaft hole 34a, and the second lower shaft hole 34b are formed by through holes that pass through in the Y-axis direction.
[0041] The first upper shaft hole 33a and the second upper shaft hole 33b are respectively provided on the upper part of a pair of planar portions 32a and 32b. The first upper shaft hole 33a is provided on the front side of the pair of planar portions 32a and 32b. Figure 5 (On the positive X-axis side), the second upper shaft hole 33b is provided on the rear side of a pair of planar portions 32a, 32b. Figure 5 The negative X-axis side). The first upper shaft hole 33a and the second upper shaft hole 33b are provided in the left-right direction (view). Figure 5 The reference shaft 45a of the first upper roller unit 40a is inserted into the first upper roller unit 40a in the first upper roller hole 33a, and the reference shaft 45b of the second upper roller unit 40b is inserted into the second upper roller hole 33b. (Viewed from the Y-axis direction) The reference shaft 45a of the first upper roller unit 40a is inserted into the first upper roller hole 33a, and the reference shaft 45b of the second upper roller unit 40b is inserted into the second upper roller hole 33b.
[0042] The first lower shaft hole 34a and the second lower shaft hole 34b are respectively provided at the lower part of a pair of planar portions 32a and 32b. The first lower shaft hole 34a is provided on the front side of the pair of planar portions 32a and 32b. Figure 5 (On the positive X-axis side), the second lower shaft hole 34b is provided on the rear side of a pair of planar portions 32a and 32b. Figure 5 The negative X-axis side). The first lower shaft hole 34a and the second lower shaft hole 34b are provided in the left-right direction (view). Figure 5The reference shaft 55a of the first lower roller unit 50a is inserted into the first lower shaft hole 34a, and the reference shaft 55b of the second lower roller unit 50b is inserted into the second lower shaft hole 34b.
[0043] The first upper shaft hole 33a and the first lower shaft hole 34a are provided in the vertical direction of the roller unit 30. Figure 5 The middle of the Z-axis direction is sandwiched along the front-back direction. Figure 5 The reference line L2 extends in the X-axis direction and is symmetrically positioned. Furthermore, the second upper shaft hole 33b and the second lower shaft hole 34b are positioned symmetrically between the reference line L2.
[0044] like Figure 5 As shown, in the front and rear directions of a pair of planar portions 32a and 32b ( Figure 5 The central portion of the X-axis direction is respectively provided with elements along the thickness direction. Figure 5 An opening 35 is formed by a through hole (in the Y-axis direction). The opening 35 is formed as an ellipse that is longer in the front-to-back direction than in the vertical direction. Figure 1 , Figure 2 As shown, the through hole of the opening 35 is along the width direction of the workpiece W. Figure 1 The opening 35 extends through the Y-axis direction. By providing the opening 35, it is possible to confirm the state in which the cutting blade 14 of the upper rotating body 11 engages with the cutting blade 24 of the lower rotating body 21, and the workpiece W is being cut.
[0045] like Figure 5 , Figure 6 As shown, the support member 31 has a first connecting portion 36a, 36b and a second connecting portion 37a, 37b connecting a pair of planar portions 32a, 32b. The first connecting portion 36a is disposed above the opening 35, and the first connecting portion 36b is disposed below the opening 35. The second connecting portion 37a is disposed between the first upper shaft hole 33a and the first lower shaft hole 34a, and the second connecting portion 37b is disposed between the second upper shaft hole 33b and the second lower shaft hole 34b.
[0046] like Figure 5 , Figure 6 As shown, a first upper side roller unit 40a, a second upper side roller unit 40b, a first lower side roller unit 50a, and a second lower side roller unit 50b are arranged between a pair of planar portions 32a and 32b.
[0047] The first upper roller unit 40a and the second upper roller unit 40b are respectively disposed on the upper part of a pair of flat portions 32a and 32b. The first upper roller unit 40a is disposed further forward than the second upper roller unit 40b. Figure 5 (positive X-axis side).
[0048] The first lower side roller unit 50a and the second lower side roller unit 50b are respectively disposed below the pair of flat portions 32a and 32b. The first lower side roller unit 50a is disposed further forward than the second lower side roller unit 50b. Figure 5 (positive X-axis side).
[0049] like Figure 6 As shown, the first upper roller unit 40a includes a roller 41a, a pair of roller retaining parts 42a and 42b, a bearing part 43, a nut 44, a reference shaft 45a, and a ring 46. The bearing part 43 is composed of an angular contact ball bearing assembled on the back side, and has an outer ring 43a, an inner ring 43b, multiple rolling elements (not shown), and a retainer 43c.
[0050] Roller 41a is formed into a cylindrical shape by means of an elastic body. Roller 41a is disposed on the outer periphery of outer ring 43a, and roller 41a and outer ring 43a are clamped by a pair of annular roller holding members 42a, 42b. On the pair of roller holding members 42a, 42b and roller 41a, there is a axial direction along roller 41a ( Figure 6 Multiple through holes (through holes in the Y-axis direction) are formed at intervals in the circumferential direction of the roller 41a. The shaft portion of a bolt 47 is inserted into the through holes of the roller retaining member 42b and the roller 41a, with the head of the bolt 47 positioned on the side of the roller retaining member 42b facing away from the roller 41a. The front end of the shaft portion of the bolt 47 engages with the screw threads formed in the through hole of the roller retaining member 42a, thereby fixing the roller 41a to the outer ring 43a.
[0051] Rings 46 are respectively arranged on the outer sides of the inner ring 43b in the thrust direction, on the left side ( Figure 6 A nut 44 is disposed on the left side of the ring 46 (on the negative Y-axis side). The reference shaft 45a is constructed of a bolt consisting of a head and a shaft portion. The reference shaft 45a is located on the head side ( Figure 6 The shaft portion (on the positive Y-axis side) has screw threads, and the front end side ( Figure 6 The shaft portion (on the negative Y-axis side) is cylindrical. The head of the reference shaft 45a is positioned on the side of the flat portion 32b facing away from the flat portion 32a. The shaft portion on the head side is inserted into the first upper shaft hole 33a, two rings 46, and inner ring 43b of the flat portion 32b. The shaft portion on the head side of the reference shaft 45a is screwed into the nut 44, thereby fixing the inner ring 43b to the reference shaft 45a. The front end of the shaft portion of the reference shaft 45a is inserted into the first upper shaft hole 33a of the flat portion 32a, thereby supporting the first upper roller unit 40a by a pair of flat portions 32a and 32b, and the roller 41a rotates around the reference shaft 45a.
[0052] The shape, structure, or function of the second upper side roller unit 40b, the first lower side roller unit 50a, and the second lower side roller unit 50b are substantially the same as those of the first upper side roller unit 40a, so the description is omitted.
[0053] like Figure 2 As shown, the upper reference roller 15 of the upper unit 10 is positioned above the first upper roller unit 40a and the second upper roller unit 40b. Furthermore, the upper reference roller 15 abuts against the roller 41a of the first upper roller unit 40a and the roller 41b of the second upper roller unit 40b. Therefore, the two rollers 41a and 41b rotate by transmitting the rotational force of the upper reference roller 15.
[0054] like Figure 2 As shown, the lower reference roller 25 of the lower unit 20 is positioned below the first lower roller unit 50a and the second lower roller unit 50b. Furthermore, the lower reference roller 25 abuts against the roller 51a of the first lower roller unit 50a and the roller 51b of the second lower roller unit 50b. Therefore, the two rollers 51a and 51b rotate by transmitting the rotational force of the lower reference roller 25.
[0055] like Figure 2 As shown, the roller unit 30 is arranged between the upper reference roller 15 and the lower reference roller 25, and the upper rotating body 11 and the lower rotating body 21 are aligned vertically ( Figure 2 The interval (in the Z-axis direction) can be adjusted with the following interval of the roller unit 30.
[0056] • The spacing between the first upper side roller unit 40a and the first lower side roller unit 50a.
[0057] • The spacing between the second upper side roller unit 40b and the second lower side roller unit 50b.
[0058] • The spacing between the first upper side roller unit 40a and the second upper side roller unit 40b.
[0059] • The spacing between the first lower side roller unit 50a and the second lower side roller unit 50b.
[0060] Moreover, such as Figure 5 As shown, the positions of the first upper roller unit 40a, the second upper roller unit 40b, the first lower roller unit 50a, and the second lower roller unit 50b are determined by the positions of the first upper shaft hole 33a, the second upper shaft hole 33b, the first lower shaft hole 34a, and the second lower shaft hole 34b, respectively. Therefore, the adjustment of the vertical spacing between the upper rotating body 11 and the lower rotating body 21 is implemented by machining these first upper shaft holes 33a, etc.
[0061] like Figure 2As shown, a third upper roller unit 40c is disposed above the upper reference roller 15 of the upper unit 10, and a third lower roller unit 50c is disposed below the lower reference roller 25 of the lower unit 20. The shape, structure, or function of the third upper roller unit 40c and the third lower roller unit 50c are substantially the same as those of the first upper roller unit 40a, and therefore description is omitted. The reference shaft 45c of the third upper roller unit 40c is supported by the support member 38. The reference shaft 55c of the third lower roller unit 50c is supported by the support member 39. The support member 39 is fixed to the base portion 81 provided at the lowest part of the cutting device 1.
[0062] The upper reference roller 15 abuts against the roller 41c of the third upper roller unit 40c. Therefore, roller 41c rotates by transmitting the rotational force of the upper reference roller 15. Furthermore, the lower reference roller 25 abuts against the roller 51c of the third lower roller unit 50c. Therefore, roller 51c rotates by transmitting the rotational force of the lower reference roller 25.
[0063] like Figure 1 , Figure 8 As shown, the cutting device 1 has two front column components 60, two rear column components 70, and a ceiling component 80. The front column components 60 are respectively disposed at the front of the cutting device 1. Figure 1 (the positive X-axis side) and the left and right directions of the cutting device 1 ( Figure 1 The rear column components 70 are respectively located at the rear of the cutting device 1 (in the Y-axis direction). Figure 1 (the negative X-axis side) and the left and right directions of the cutting device 1 ( Figure 1 The two ends of the front pillar component 60 and the rear pillar component 70 are formed in a vertical direction (in the Y-axis direction). Figure 1 It is roughly rectangular in shape (viewed from the Z-axis) and extends in the vertical direction.
[0064] like Figure 1 , Figure 8 As shown, an upper support unit 16 and a lower support unit 26 are arranged between the front column component 60 and the rear column component 70. In other words, the workpiece W conveying direction of the upper support unit 16 and the lower support unit 26 ( Figure 1 A front pillar component 60 is provided on the upstream side (in the direction of arrow C), and a rear pillar component 70 is provided on the downstream side.
[0065] The ceiling component 80 is positioned at the top of the cutting device 1. The ceiling component 80 is configured to be viewed vertically (…). Figure 1 The ceiling component 80 is roughly H-shaped and flat when viewed from the Z-axis direction. It is placed on the upper surfaces of the two front column components 60 and the two rear column components 70 and is fixed by a fixing mechanism.
[0066] like Figure 4 , Figure 7 As shown, two upper through holes 61 and two lower through holes 62 are formed on the two front pillar components 60, respectively. Additionally, the right side (not shown) Figure 4 The upper through hole 61 and lower through hole 62 of the front column component 60 (on the positive Y-axis side). The two upper through holes 61 are located in front of the upper support unit 16 (on the positive Y-axis side). Figure 4 (in the positive X-axis direction), two lower through holes 62 are provided in front of the lower support unit 26. Two upper through holes 61 and two lower through holes 62 are located along the front-back direction (in the positive X-axis direction). Figure 4 It is constructed by a through hole (in the X-axis direction) and is visible in the front and back directions (in the X-axis direction). Figure 4 It forms a circular shape when viewed from the X-axis direction.
[0067] like Figure 4 , Figure 7 As shown, the two upper through holes 61 have a large-diameter portion 61a and a small-diameter portion 61b. The large-diameter portion 61a is formed in front of the small-diameter portion 61b. Figure 4 The lower through hole 62, like the upper through hole 61, has a large diameter portion 62a and a small diameter portion 62b.
[0068] like Figure 4 As shown, upper spring units 63 are respectively arranged in the two upper through holes 61. Figure 7 As shown, the upper spring unit 63 has a pair of spring supports 66, a helical spring 65, and a bolt 64.
[0069] A pair of spring support portions 66 are each formed in the shape of a circular plate, with a through hole formed in the center of each hole extending along the thickness direction. The pair of spring support portions 66 are arranged with their planar portions facing each other, and a helical spring 65 is disposed between them. The helical spring 65 is arranged with its axis centered along the front-rear direction (…). Figure 7 The coil spring 65 and a pair of spring supports 66 are disposed on the large diameter portion 61a.
[0070] Bolt 64 consists of a head and a shaft, with threads formed on the front end of the shaft. Bolt 64 is configured such that the shaft center is along the front-rear direction (…). Figure 7 (in the X-axis direction). The head of bolt 64 is positioned on the front side ( Figure 7 The side of the spring support 66 (on the positive X-axis side) opposite to the side of the coil spring 65. The shaft of the bolt 64 is inserted into a pair of spring supports 66, the coil spring 65 and the small diameter portion 61b.
[0071] If the shaft portion at the front end of bolt 64 is screwed into the screw hole 16e formed in the housing 16a of the upper support unit 16, the upper support unit 16 is stretched by the biasing force of the helical spring 65 along the direction of the front column member 60 and comes into contact with the front column member 60. Thus, the upper rotating body 11, through the upper spring unit 63, moves the workpiece W in the conveying direction ( Figure 7 The upper spring unit 63 is positioned in the X-axis direction. The upper spring unit 63 functions as an upper tensioning mechanism that stretches the upper support unit 16 in the direction of the front column member 60.
[0072] like Figure 4 As shown, lower spring units 68 are respectively arranged in the two lower through holes 62. The shape, structure, or function of the lower spring units 68 are substantially the same as those of the upper spring unit 63, so the description is omitted. The lower support unit 26 is also stretched by the lower spring units 68 along the direction of the front column member 60 and comes into contact with the front column member 60, thereby positioning the conveying direction of the workpiece W of the lower rotating body 21. The lower spring units 68 function as a lower stretching mechanism that stretches the lower support unit 26 along the direction of the front column member 60. Alternatively, the upper spring unit 63 and the lower spring unit 68 can be provided on the rear column member 70, and the rear column member 70 can be used to position the conveying direction of the workpiece W of the upper rotating body 11 and the lower rotating body 21.
[0073] like Figure 8 As shown, two upper reference pins 67 are disposed on the front pillar component 60 on the right side. The upper reference pins 67 are located in front of the upper support unit 16. Figure 8 (positive X-axis), and in the left and right directions ( Figure 8 The upper reference pins 67 are arranged in a generally rod-shaped configuration along the front-to-back direction (Y-axis direction). Figure 8 (in the X-axis direction). A rearward extension is formed at the front end of the upper support unit 16 side of the upper reference pin 67, which is further rearward than the front column member 60. Figure 8 The protrusion 67a protrudes from the negative X-axis side. The protrusions 67a formed in the two upper reference pins 67 respectively clamp the convex portion 16f formed on the housing 16a of the upper support unit 16. The convex portion 16f is provided on the side of the front pillar member 60 of the housing 16a and is formed by a flat plate-shaped protrusion protruding along the direction of the front pillar member 60. The convex portion 16f extends along the vertical direction (…). Figure 8 The protrusion 16f is positioned in the left-right direction (Z-axis direction). Figure 8 The upper reference pin 67 is clamped by the protrusion 67a of the upper reference pin 67 on both outer sides (in the Y-axis direction), so the upper rotating body 11 is clamped by the upper reference pin 67 in the width direction of the workpiece W (in the Y-axis direction). Figure 8 The Y-axis direction is used for positioning.
[0074] Although not shown, two lower reference pins are also disposed on the right-side front post component 60 in front of the lower support unit 26. The shape, structure, or function of these lower reference pins are substantially the same as those of the upper reference pin 67, so description is omitted.
[0075] like Figure 2 , Figure 9 As shown, a pressing unit 90 is provided on the upper part of the cutting device 1. The pressing units 90 are respectively positioned above the third upper side roller unit 40c located at both ends of the cutting device 1 in the left-right direction. Figure 9 As shown, the pressing unit 90 includes a crossbar component 91, a load sensor 92, a pressing structure 93, an adjusting screw 94, a guide 95, a vertical bar component 96, and a thrust bearing 97.
[0076] The crossbar component 91 is composed of components along the front-to-back direction ( Figure 9 A crossbar component with a rectangular cross-section extending in the X-axis direction is formed. The crossbar component 91 is fixed to the support component 38 disposed on the lower surface by a fixing mechanism 91a. A compression type load sensor 92 is mounted on the upper surface of the crossbar component 91. Screw holes 91b opening upwards are provided at both ends of the crossbar component 91 in the front-rear direction. Vertical bar components 96 extending in the vertical direction are screwed into the two screw holes 91b respectively.
[0077] A guide portion 95 provided on the ceiling component 80 is provided with a feature extending in the vertical direction ( Figure 9 A through hole (in the Z-axis direction) is formed, and an adjusting screw 94 is inserted into the through hole. The adjusting screw 94 is positioned along the up-down direction ( Figure 9 Extending along the Z-axis, a thrust bearing support 94a is formed in the central portion of the shaft in the vertical direction, and screw threads are formed in the lower end portion of the shaft. The thrust bearing support 94a extends radially outward from the shaft and then bends approximately at a right angle towards the ceiling component 80. An annular thrust bearing 97 is disposed between the thrust bearing support 94a and the ceiling component 80.
[0078] A pressing structure 93 is disposed between the ceiling component 80 and the load sensor 92. The pressing structure 93 has a first connecting component 93a, a second connecting component 93b, and a pressing component 93c. The first connecting component 93a is formed in a generally cuboid shape, and in the front-back direction ( Figure 9 A through hole 93d is formed in the center of the part (in the X-axis direction) by a hole that runs through the vertical direction.
[0079] The through hole 93d has a first through hole 93d1 and a second through hole 93d2. The first through hole 93d1 is located above the second through hole 93d2 and is formed into a circular cross-section. Screw threads are formed on the wall surface of the first through hole 93d1, and the first through hole 93d1 is screwed into an adjusting screw 94. The second through hole 93d2 is formed into a rectangular cross-section, with a front-to-back direction (…). Figure 9 The size of the hole (in the X-axis direction) is larger than that of the first through hole 93d1. A second connecting member 93b and a pressing member 93c are disposed in the second through hole 93d2.
[0080] The second connecting member 93b, which is generally rectangular, has through holes formed at both ends in the front-rear direction, which are formed by holes extending in the vertical direction. The second connecting member 93b is fixed to the first connecting member 93a by bolts 93e inserted into the through holes. A through hole formed in the center of the second connecting member 93b in the front-rear direction is formed, which is formed by holes extending in the vertical direction. A pressing member 93c is fitted into the through hole. The pressing member 93c is formed by a rod-shaped member extending in the vertical direction and is placed on the upper surface of the load sensor 92.
[0081] Two holes 80a are provided at both ends of the ceiling component 80 in the front-rear direction. A cylindrical cylinder 80b is fitted into each of the two holes 80a, and a longitudinal rod component 96 is inserted into each cylinder 80b. Two holes 93f are provided at both ends of the first connecting component 93a in the front-rear direction. The two holes 93f are located below the two holes 80a of the ceiling component 80. A cylindrical cylinder 93g is fitted into each of the two holes 93f, and a longitudinal rod component 96 is inserted into each cylinder 93g.
[0082] The pressing unit 90 can move the pressing structure 93 downward by rotating the adjusting screw 94. Specifically, when the adjusting screw 94 is rotated, the upward movement of the adjusting screw 94 is restricted by the thrust bearing 97, and the pressing structure 93 moves downward. When the pressing structure 93 moves downward, the third upper roller unit 40c is pressed downward via the load sensor 92, the crossbar member 91, and the support member 38. By pressing the third upper roller unit 40c downward, pressure is applied to the upper reference roller 15 and the lower reference roller 25 in the vertical direction. By applying this pressure, the vertical distance between the upper rotating body 11 and the lower rotating body 21 can be kept constant. The magnitude of the applied pressure can be confirmed and adjusted by the load sensor 92.
[0083] Next, the assembly method of the cutting device 1 will be described. Before assembly, the upper unit 10, the lower unit 20, the roller unit 30 and the ceiling component 80 are removed from the cutting device 1.
[0084] First, the lower support unit 26 of the lower unit 20 is inserted from above the cutting device 1 between the front column member 60 and the rear column member 70. Then, the lower reference roller 25 is placed on the roller 51c of the third lower roller unit 50c.
[0085] Next, the lower support unit 26 is brought into contact with the front column component 60 by the lower spring unit 68, thereby positioning the lower rotating body 21 in the front-rear direction.
[0086] Next, the roller 51a of the first lower roller unit 50a and the roller 51b of the second lower roller unit 50b of the roller unit 30 are placed on the lower reference roller 25.
[0087] Next, the upper support unit 16 of the upper unit 10 is inserted from above the cutting device 1 between the front column member 60 and the rear column member 70. Furthermore, the upper reference roller 15 is placed on the roller 41a of the first upper roller unit 40a and the roller 41b of the second upper roller unit 40b.
[0088] Next, the upper support unit 16 is brought into contact with the front column component 60 by the upper spring unit 63, and the upper rotating body 11 is positioned in the front-rear direction.
[0089] Next, the ceiling component 80 with the pressing unit 90 installed is placed on the upper part of the cutting device 1, and the roller 41c of the third upper roller unit 40c is placed on the upper reference roller 15.
[0090] Finally, the pressing unit 90 applies a specified pressure to the upper reference roller 15 and the lower reference roller 25 from the vertical direction to adjust the vertical spacing between the upper rotating body 11 and the lower rotating body 21.
[0091] In this embodiment, a roller unit 30 is disposed between the upper reference roller 15 and the lower reference roller 25. The roller unit 30 has a first upper roller unit 40a and a second upper roller unit 40b that abut against and rotate with the upper reference roller 15. Furthermore, the roller unit 30 has a first lower roller unit 50a and a second lower roller unit 50b that abut against and rotate with the lower reference roller 25. With this structure, the vertical direction ( Figure 2 The interval (in the Z-axis direction) can be adjusted by the following interval of the roller unit 30.
[0092] • The spacing between the first upper side roller unit 40a and the first lower side roller unit 50a.
[0093] • The spacing between the second upper side roller unit 40b and the second lower side roller unit 50b.
[0094] • The spacing between the first upper side roller unit 40a and the second upper side roller unit 40b.
[0095] • The spacing between the first lower side roller unit 50a and the second lower side roller unit 50b.
[0096] These interval adjustments do not require the roller unit 30 to be installed in the cutting device 1, thus optimizing the vertical interval between the upper rotating body 11 and the lower rotating body 21 without large-scale processing.
[0097] In this embodiment, an opening 35 is formed on the support member 31 of the roller unit 30, which is a hole extending through the width direction of the workpiece W. By providing the opening 35, it is possible to confirm the state in which the cutting blade 14 of the upper rotating body 11 is engaged with the cutting blade 24 of the lower rotating body 21 and the workpiece W is being cut.
[0098] In this embodiment, a front column member 60 extending in the vertical direction is provided upstream of the workpiece W conveying direction of the upper support unit 16 and the lower support unit 26. An upper spring unit 63 that stretches the upper support unit 16 along the direction of the front column member 60 and a lower spring unit 68 that stretches the lower support unit 26 along the direction of the front column member 60 are provided on the front column member 60. By providing the upper spring unit 63 and the lower spring unit 68, the upper support unit 16 and the lower support unit 26 contact the front column member 60, enabling positioning of the workpiece W conveying direction of the upper rotating body 11 and the lower rotating body 21.
[0099] Furthermore, the present invention is not limited to the above-described embodiments, and appropriate modifications can be made without departing from the spirit of the invention.
